The air path forming body 13 can be used with the floor brush 23 removed, for example, or the floor brush 23 and the extension pipe 22 can be removed.

  The hose body 21 includes a long cylindrical hose body 25, a connecting pipe portion 26 formed in communication with the base end side (downstream end side) which is one end side of the hose body 25, For example, a hand operating part 27 for gripping operation of the air passage forming body 13 is formed integrally with the front end side (upstream end side) which is the end side.

  The hose body 25 is formed in a cylindrical bellows shape using a flexible synthetic resin or the like, and a wiring (not shown) that electrically connects the hand operating section 27 side and the cleaner body 12 side is provided inside and the air passage. It is attached to the outside of W in a spiral shape.

  The connecting pipe portion 26 is a portion that is inserted and connected to the main body suction port 19 and is formed in a cylindrical shape from a synthetic resin harder than the hose main body 25. In addition, a terminal (not shown) that is electrically connected to the wiring disposed in the hose body 25 is disposed in the connecting pipe part 26, and these terminals insert the connecting pipe part 26 into the main body suction port 19. By connecting, it is electrically connected to the cleaner body 12 side. An optical sensor 33 as a dust amount detecting means for detecting the amount of dust passing through the air passage W is disposed inside the main body suction port 19 to which the connecting pipe portion 26 is connected, as shown in FIG. Has been.

  Here, as shown in FIGS. 1 and 2, the optical sensor 33 includes, for example, a light emitting unit 35 as a light emitting unit that emits infrared light, and a light receiving unit that receives the infrared light emitted by the light emitting unit 35. The light receiving unit 36 is provided at a position facing each other, and a signal corresponding to the amount of dust passing through the air passage W is controlled by the amount of infrared light received by the light receiving unit 36 from the light emitting unit 35. Output to 37 is possible.

  The light emitting unit 35 includes a light emitting element 35a such as an LED that outputs light such as infrared light, and one and the other light emitting side as a light emitting side light guide member that guides light emitted from the light emitting element 35a into the air path W. Lenses 35b and 35c.

  The light emitting element 35a is disposed, for example, at the upper part of the main body suction port 19 of the cleaner body 12, and is configured to output infrared light downward. The light emitting element 35a has an anode side electrically connected to the power supply unit 38 via a resistor R1 such as a variable resistor, and a cathode side grounded.

  One light-emitting side lens 35b is disposed on the inner surface of the main body suction port 19 below the infrared light output side of the light-emitting element 35a.

  The other light-emitting side lens 35c is arranged at a position facing the lower side of the light-emitting element 35a (light-emitting side lens 35b) in a state where the connecting pipe portion 26 of the air passage forming body 13 is connected to the main body suction port 19. . The other light-emitting side lens 35c is fitted in a light-emitting side hole 35d formed in the connecting pipe portion 26 along the radial direction so as to air-tightly close the light-emitting side hole 35d. One end side faces the light emitting element 35a side (light emitting side lens 35b side), and the other end side faces the inside of the air passage W. That is, the air in the air passage W does not flow out of the air passage W from the light emitting side hole 35d.

  Similarly, the light receiving unit 36 includes a light receiving element 36a such as a phototransistor that detects infrared light output from the light emitting unit 35, and a light receiving side light guide member that guides the light output from the light emitting unit 35 to the light receiving element 36a. And the other light receiving side lenses 36b and 36c.

  The light receiving element 36a is arranged, for example, below the main body inlet 19 of the cleaner body 12 and upward, that is, toward the light emitting element 35a, and is configured to receive infrared light output from the light emitting element 35a. Has been. The light receiving element 36a constitutes a so-called emitter grounding circuit in which the collector side is electrically connected to the resistor R2 connected in parallel to the resistor R1 to the power supply unit 38, and the emitter side is grounded. The connection point between the resistor R2 that is the output unit and the collector side is electrically connected to the amplifying unit 39 and the control means 37, which are constituted by, for example, an OP amplifier.

  One light-receiving side lens 36b is disposed on the inner surface of the main body suction port 19 above the infrared light input side with respect to the light-receiving element 36a.

  Further, the other light receiving side lens 36c is disposed at a position facing the upper side of the light receiving element 36a (light receiving side lens 36b) in a state where the connecting pipe portion 26 of the air passage forming body 13 is connected to the main body suction port 19. . The other light receiving side lens 36c is fitted in a light receiving side hole 36d formed in the connecting pipe portion 26 along the radial direction so as to airtightly close the light receiving side hole 36d. One end faces the light receiving element 36a side (light receiving side lens 36b side), and the other end faces the inside of the air passage W. That is, the air in the air passage W does not flow out of the air passage W from the light receiving side hole 36d.

  The control means 37 controls the phase of the operation of the electric blower 18 through, for example, a triac Tr1 as an electric blower control element, and is disposed in, for example, the exhaust air passage of the electric blower 18. The control means 37 is supplied with power from a commercial AC power source e via a power cord (not shown), for example.

  The power supply unit 38 is connected to the commercial AC power source e when the power cord is electrically connected, that is, when power (voltage) is applied (turned on), in other words, when plugged in. This is a constant voltage source that generates a predetermined constant voltage, for example, a voltage of 5 V, by feeding from e.

  The amplifying unit 39 is electrically connected to the control means 37 via the pulse shaper 40.

  Further, as shown in FIG. 3, the hand operating section 27 is formed in a substantially cylindrical shape by a synthetic resin harder than the hose body 25 and is gripped by the user from the upstream end side to the downstream end side. A gripping portion 41 is formed so as to protrude. A plurality of setting buttons 42 as setting means for setting the operation of the electric blower 18 and the like in the control means 37 (FIG. 1) are arranged in the grip portion 41. These setting buttons 42 are electrically connected to the control means 37 (FIG. 1) in the cleaner body 12 through the wiring in the hose body 25. Further, an operation detection unit 45 for detecting the operation of the hand operation unit 27 is disposed inside the grip unit 41. This motion detection means 45 is a known one such as an inclination sensor, and whether or not the hand operation unit 27 is operating (still), in other words, the user operates (uses) the hand operation unit 27. It is possible to detect whether or not. The operation detecting means 45 is electrically connected to the control means 37 as shown in FIG.

  Further, the floor brush 23 shown in FIG. 3 can constitute a part (upstream end) of the air passage W, and a connecting pipe 47 whose one end side is connected to the distal end side (upstream end side) of the extension pipe 22. And a laterally long case body 48 connected to the other end side of the connecting pipe 47 so as to be rotatable in the vertical direction or the circumferential direction, and can run on the surface to be cleaned. Further, a suction port communicating with the other end side of the connection pipe 47 is formed in the lower portion of the case body 48 facing the floor surface.

  Next, the operation of the first embodiment will be described with reference to the matrix shown in FIG. 4 and the flowchart shown in FIG.

  When the user attaches (plugs in) the power cord to a wall outlet or the like with the dust collecting unit mounted in the vacuum cleaner body 12, the commercial AC power source e is supplied to the control means 37 and the power source unit 38. Power (voltage) is supplied (applied) from

  The control means 37 waits for an operation input of the setting button 42 and drives the electric blower 18 in the operation mode set by the user by operating the setting button 42 or stops the electric blower 18 being driven. Hereinafter, the operation of each part when the electric blower 18 is driven in the automatic mode, that is, the mode in which the input is automatically controlled by the control means 37 will be described.

  After the electric blower 18 is driven, the user moves the floor brush 23 back and forth on the surface to be cleaned through the gripping portion 41, and the dust on the surface to be cleaned is blown by the negative pressure of the driven electric blower 18. The air is sucked together with the air through the path W and collected in the dust collecting part.

  In this cleaning state, the control means 37, for example, amplifies the output signal output from the optical sensor 33 by the amplifying unit 39 and performs pulse shaping by the pulse shaper 40 to input the inside of the air path W. The amount of dust passing through is monitored. In other words, the vacuum cleaner 11 detects the amount of dust by the optical sensor 33 (step 1).

  That is, when dust passes through the air path W, the dust blocks light emission from the light emitting element 35a of the light emitting unit 35. Therefore, the amount of light received by the light receiving element 36a of the light receiving unit 36 decreases, so that The passage of dust can be detected by the optical sensor 33. Therefore, as the amount of dust passing through the air path W increases, the amount of light received by the light receiving element 36a of the light receiving unit 36 decreases, so that the output signal from the optical sensor 33 is amplified by the amplification unit 39 and is amplified by the pulse shaper 40. Since the input signal that is pulse-shaped and input to the control means 37 becomes relatively small, the control means 37 can control the amount of dust that passes through the air passage W (at the position of the surface to be cleaned). A large number can be determined by the magnitude of the input signal.

  Then, the control means 37 determines whether or not the dust amount detected by the optical sensor 33 is equal to or greater than a predetermined amount by comparing the input signal with a preset threshold value (step S40). 2) When it is determined that the amount is not equal to or greater than the predetermined amount (less than the predetermined amount), the control unit 37 determines whether or not the hand operating unit 27 is operating by the operation detecting unit 45 (step 3).

  In step 3, when the control means 37 determines that the hand operation unit 27 is not operating (the hand operation unit 27 is stationary), for example, the user does not hold the hand operation unit 27, Assuming that the vacuum cleaner 11 (the electric blower 18) is driven, for example, a cleaning state in which the air passage forming body 13 is left unattended, the control means 37 is configured as a triac Tr1. The phase angle of the input of the electric blower 18 set by the above is set to a predetermined first value for the electric blower that is the smallest predetermined minimum value, and the electric blower 18 is set to a predetermined first electric blower input (power 1) that is the lowest input. Operate (step 4).

  In step 3, when the control means 37 determines that the hand operation unit 27 is operating (the hand operation unit 27 is not stationary), for example, the user reciprocates the floor brush 23 back and forth as usual. This control means 37 assumes that the phase angle of the input of the electric blower 18 set by the triac Tr1 is the first value for the electric blower. The electric blower 18 is operated with a predetermined second electric blower input (power 2) larger than the first electric blower input as the second value for the predetermined electric blower larger than the first electric blower (step 5).

  On the other hand, when it is determined in step 2 that the amount of dust detected by the optical sensor 33 is greater than or equal to a predetermined amount, the control means 37 determines whether or not the hand operating section 27 is operating by the operation detecting means 45 (step 6).

  In this step 6, when the control means 37 determines that the hand operation section 27 is not operating (the hand operation section 27 is stationary), for example, a cleaning state of a place where dust is partially accumulated near the wall or the like Assuming that, the control means 37 sets the electric blower 18 to the second value by setting the phase angle of the input of the electric blower 18 set by the triac Tr1 as a predetermined third value for the electric blower larger than the second value for the electric blower. Operation is performed with a predetermined third electric blower input (power 3) larger than the electric blower input (step 7).

  In Step 6, when the control means 37 determines that the hand operation unit 27 is operating (the hand operation unit 27 is not stationary), for example, the amount of dust on the surface to be cleaned is large, and the user Assuming that the floor brush 23 is reciprocated back and forth as usual for cleaning, the control means 37 determines the phase angle of the input of the electric blower 18 set by the triac Tr1 for the third electric blower. The electric blower 18 is operated with a predetermined fourth electric blower input (power 4) larger than the third input as a predetermined fourth value for electric blower larger than the value (step 8).

  That is, a cleaning state is assumed based on the amount of dust detected by the optical sensor 33 and the operation state of the hand operation unit 27 detected by the operation detection unit 45, and the control unit 37 corresponds to the assumed cleaning state. By controlling the driving (input) of the electric blower 18, it is possible to accurately assume the user's cleaning state based on two pieces of information, the information from the optical sensor 33 and the information from the motion detection means 45, and to the cleaning state. It can be cleaned with suitable power.

  Next, a second embodiment will be described with reference to FIGS. In addition, about the structure and effect | action similar to the said 1st Embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  In the second embodiment, the floor brush 23 is provided with a rotating brush 51 as a rotating cleaning body in the first embodiment.

  That is, as shown in FIG. 7, the floor brush 23 has a rotary brush 51 rotatably attached to a horizontally long suction port formed in the lower surface facing the surface to be cleaned of the case body 48. The rotating brush 51 is connected to an electric motor 52 accommodated in the case body 48 via a transmission means 53 such as a belt, and is rotated by the electric motor 52.

  The rotating brush 51 scrapes off dust that has entered or entangled with the surface to be cleaned by rotation. The rotating brush 51 can have an arbitrary configuration, but preferably includes a cleaning member such as a bristle brush or a blade.

  As shown in FIG. 6, the phase of the electric motor 52 is controlled by the control means 37 via a triac Tr2 as an electric motor control element. The electric motor 52 is turned on / off simultaneously with the on / off of the electric vacuum cleaner 11 (electric blower 18) (corresponding to the on / off). The control means 37 and the electric motor 52 (triac Tr2) are electrically connected by a wiring (not shown) that passes through the inside of the air passage forming body 13.

  Next, the operation of the second embodiment will be described with reference to the matrix shown in FIG. 8 and the flowchart shown in FIG.

  In step 3 of the first embodiment, when the control unit 37 determines that the hand operation unit 27 is not operating (the hand operation unit 27 is stationary), for example, the user holds the hand operation unit 27. Control, assuming that the vacuum cleaner 11 (electric blower 18) is driven and the air path forming body 13 is left unattended, such as a cleaning state in which the air path forming body 13 is left unattended. The means 37 sets the phase angle of the input of the electric blower 18 set by the triac Tr1 as the first value for the electric blower, operates the electric blower 18 with the first electric blower input (power 1), and sets it with the triac Tr2. By setting the phase angle of the input of the motor 52 to be the first predetermined value for the predetermined motor, which is the smallest predetermined minimum value, by operating the motor 52 with the predetermined first motor input that is the lowest input, the rotary brush 51 is minimized. In revolutions That is rotated at a predetermined first revolution speed (rpm 1) (step 11).

  In step 3, when the control means 37 determines that the hand operation unit 27 is operating (the hand operation unit 27 is not stationary), for example, the user reciprocates the floor brush 23 back and forth as usual. However, the control means 37 sets the phase angle of the input of the electric blower 18 set by the triac Tr1 as the second electric blower for the electric blower. As a value, the electric blower 18 is operated by the second electric blower input (power 2) and the phase angle of the input of the electric motor 52 set by the triac Tr2 is a predetermined second value for the motor that is larger than the first value for the motor. As described above, by operating the motor 52 with a predetermined second motor input larger than the first motor input, the rotary brush 51 is rotated at a predetermined second rotation speed (rotation speed 2) larger than the first rotation speed ( Ste Flop 12).

  Furthermore, when the control unit 37 determines in step 6 that the hand operation unit 27 is not operating (the hand operation unit 27 is stationary), a large amount of dust is accumulated, for example, near the wall of the carpet. Assuming a clean state of the place, the control means 37 uses the phase angle of the input of the electric blower 18 set by the triac Tr1 as the third value for the electric blower, and sets the electric blower 18 to the third electric blower input (power 3), the phase angle of the input of the motor 52 set by the triac Tr2 is set to a predetermined third value for the motor larger than the second value for the motor, and the motor 52 is set to a predetermined first value larger than the second motor input. By operating with three electric motor inputs, the rotating brush 51 is rotated at a predetermined third rotational speed (rotational speed 3) larger than the second rotational speed (step 13).

  In step 6, when the control means 37 determines that the hand operation unit 27 is operating (the hand operation unit 27 is not stationary), for example, the amount of dust on the surface to be cleaned is large, and the user Assuming that the floor brush 23 is reciprocated back and forth as usual for cleaning, the control means 37 determines the phase angle of the input of the electric blower 18 set by the triac Tr1 for the electric blower As the four values, the electric blower 18 is operated with the fourth electric blower input (power 4), and the phase angle of the input of the electric motor 52 set by the triac Tr2 is larger than the third value for the electric motor. As a value, by operating the motor 52 with a predetermined fourth motor input larger than the third motor input, the rotary brush 51 is rotated at a predetermined fourth rotation speed (rotation speed 4) larger than the third rotation speed. (Stay Flop 14).

  Thus, the control means 37 assumes a cleaning state based on the amount of dust detected by the optical sensor 33 and the operation of the hand operation unit 27 detected by the operation detection means 45, and corresponds to the assumed cleaning state. By controlling the driving of the electric blower 18 and the electric motor 52 (the rotating brush 51), not only the electric blower 18, but also the electric motor 52 (the rotating brush 51) can be driven in a state suitable for the cleaning state. Further, cleaning can be performed with electric power suitable for the cleaning state, energy saving can be achieved, and dust on the surface to be cleaned can be scraped off by the electric motor 52 (the rotating brush 51), so that the cleaning performance can be further improved.

  Next, a third embodiment will be described with reference to FIGS. In addition, about the structure and effect | action similar to said each embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  In the third embodiment, in the first embodiment, the floor brush 23 is provided with a grounding detection means 55 for detecting the grounding state of the floor brush 23.

  As shown in FIG. 11, the ground detection means 55 is movably attached to an opening 56 formed on the lower surface of the case body 48 facing the surface to be cleaned. The grounding detection means 55 has a wheel 57 as a grounding part and a change-over switch (not shown) that is switched on / off by the grounding / non-grounding of the wheel 57. The wheel 57 rotates to the support member 59. The support member 59 is pivotally supported by the case body 48 so as to be rotatable. Then, when the floor brush 23 is brought into contact with the surface to be cleaned (grounded), the wheel 57 contacts the surface to be cleaned so that the wheel 57 rotates together with the support member 59 and is stored in the opening 56. When the support member 59 turns on the changeover switch, the grounding of the floor brush 23 is detected, and when the floor brush 23 is separated from the surface to be cleaned (ungrounded), the wheel 57 opens together with the support member 59. The support member 59 protrudes from the portion 56 and is separated from the changeover switch. When the changeover switch is turned off, the non-grounding of the floor brush 23 is detected.

  Further, as shown in FIG. 10, the ground detection means 55 is electrically connected to the control means 37, and the control means 37 is connected to the ground brush 23 by means of an on / off switch of the ground detection means 55. It is configured to recognize non-grounding. The ground contact detection means 55 and the control means 37 are electrically connected by a wiring (not shown) that passes through the inside of the air passage forming body 13. Therefore, for example, when the floor brush 23 is removed from the extension pipe 22, or when the extension pipe 22 and the floor brush 23 are removed from the hand operation section 27, another suction port, such as a vine mouth, is attached to the hand operation section 27. Are connected to each other, the electrical connection between the ground detection means 55 and the control means 37 is cut off, so that the control means 37 is configured to determine that the floor brush 23 is not grounded. . That is, the grounding detection means 55 indirectly detects whether the floor brush 23 is used by detecting the grounding / non-grounding of the floor brush 23 or whether the floor brush 23 is removed and another suction port is used. It has a function of a connection detecting means for judging. For this reason, hereinafter, the ground / non-ground detected by the ground detecting means 55 by the control means 37 includes the connection / non-connection of the floor brush 23.

  Next, the operation of the third embodiment will be described with reference to the matrix shown in FIG. 12 and the flowchart shown in FIG.

  First, in step 3, when the control means 37 determines that the hand operation section 27 is not operating (the hand operation section 27 is stationary), the control means 37 is detected by the ground detection means 55 by the floor brush 23. It is determined whether or not is grounded (step 21).

  In step 21, when it is determined that the floor brush 23 is not grounded, the control means 37 has a small amount of dust on the surface to be cleaned, for example, and the user removes the floor brush 23 (and the extension pipe 22). For example, a state in which another suction port body such as a vine mouth is connected and the user does not hold the hand operating unit 27 and is not cleaned as usual, for example, the vacuum cleaner 11 (electric blower 18) Assuming a cleaning state in which the air passage forming body 13 is left with the air passage driven, the control means 37 sets the input phase angle of the electric blower 18 set by the triac Tr1 as the first value for the electric blower. Then, the electric blower 18 is operated by the first electric blower input (power 1) (step 22).

  Further, when it is determined in step 21 that the floor brush 23 is grounded, the control means 37, for example, has a small amount of dust on the surface to be cleaned. The control means 37 assumes that the phase angle of the input of the electric blower 18 set by the triac Tr1 is the second value for the electric blower, and assumes the electric blower 18 as described above. It operates with the second electric blower input (power 2) (step 23).

  In step 3, when the control unit 37 determines that the hand operation unit 27 is operating (the hand operation unit 27 is not stationary), the control unit 37 is connected to the ground detection unit 55 as in step 21. Thus, it is determined whether or not the floor brush 23 is grounded (step 24).

  In step 24, when it is determined that the floor brush 23 is not grounded, the control means 37 suspends the floor brush 23 (and the extension pipe 22), for example, although the amount of dust on the surface to be cleaned is small. Assuming a cleaning state in which another suction port body such as a mouth is connected for cleaning, the control means 37 sets the phase angle of the input of the electric blower 18 set by the triac Tr1 to the second value for the electric blower. Then, the electric blower 18 is operated with the second electric blower input (power 2) (step 25).

  Further, when it is determined in step 24 that the floor brush 23 is grounded, the control means 37 performs cleaning by grounding the floor brush 23 on the surface to be cleaned although the amount of dust on the surface to be cleaned is small, for example. Assuming a cleaning state, the control means 37 sets the phase angle of the input of the electric blower 18 set by the triac Tr1 as the third value for the electric blower, and makes the electric blower 18 the third electric blower input (power 3). (Step 26).

  On the other hand, in step 6, when the control means 37 determines that the hand operation section 27 is not operating (the hand operation section 27 is stationary), the control means 37 detects the ground contact in the same manner as steps 21 and 24. It is determined by means 55 whether the floor brush 23 is grounded (step 27).

  In step 27, when it is determined that the floor brush 23 is not grounded, the control means 37, for example, removes the floor brush 23 in a narrow space such as a gap between the furniture and the wall. The control means 37 is set by the TRIAC Tr1, assuming that the suction port body is stationary and cleaned for a predetermined time in order to connect the suction port body and suck in the dust accumulated by the suction air volume. The electric blower 18 is operated with the third electric blower input (power 3) by setting the phase angle of the input of the electric blower 18 to be the third value for the electric blower (step 28).

  Further, when it is determined in step 27 that the floor brush 23 is grounded, the control means 37 assumes a cleaning state in which, for example, the corner of the surface to be cleaned or the wall is cleaned with the floor brush 23. The control means 37 operates the electric blower 18 with the fourth electric blower input (power 4) with the phase angle of the input of the electric blower 18 set by the triac Tr1 as the fourth value for the electric blower (step 29). .

  Further, when the control unit 37 determines in step 6 that the hand operation unit 27 is operating (the hand operation unit 27 is not stationary), as in steps 21, 24 and 27, the control unit 37 The ground detection means 55 determines whether or not the floor brush 23 is grounded (step 30).

  When it is determined in step 30 that the floor brush 23 is not grounded, the control means 37 applies, for example, the floor brush 23 (and extension) to a wide range of surfaces to be cleaned, such as on a shelf with a large amount of dust. Assuming that the pipe 22) is removed and cleaning is performed using another suction port such as a furniture brush, the control means 37 sets the input phase angle of the electric blower 18 set by the triac Tr1 as described above. As the fourth value for the electric blower, the electric blower 18 is operated with the fourth electric blower input (power 4) (step 31).

  Further, when it is determined in step 30 that the floor brush 23 is grounded, the control means 37, for example, has a large amount of dust on the surface to be cleaned, and the user grounds the floor brush 23 and moves back and forth as usual. Assuming that the floor brush 23 is reciprocated for cleaning, the control means 37 sets the maximum phase angle of the input of the electric blower 18 set by the triac Tr1 to be larger than the fourth value for the electric blower. The electric blower 18 is operated with a predetermined fifth electric blower input (power 5) which is a maximum input larger than the fourth electric blower input as the predetermined fifth value for electric blower (step 32).

  In this way, the grounding state (connection state) of the suction inlet body such as the floor brush 23 or the sill mouth is detected by the grounding detection means 55, and the control unit 37 detects the amount of dust detected by the optical sensor 33 and the motion detection means 45. Assuming the cleaning state based on the operation of the hand operating unit 27 detected by the above and the grounding state (connection state) of the suction port body detected by the grounding detection means 55, the electric blower 18 corresponding to the assumed cleaning state By controlling the drive, the user's cleaning state is assumed more accurately based on the three types of information: the information from the optical sensor 33, the information from the motion detection means 45, and the information from the ground detection means 55. It is possible to perform cleaning with electric power more suitable for the cleaning state, and further energy saving is possible. That is, for example, when the floor brush 23 is grounded (connected), the input (power (suction force) of the electric blower 18 is higher than when the floor brush 23 is not grounded (not connected). )) Is increased, for example, when the surface to be cleaned such as the floor surface is cleaned using the floor brush 23 that requires power, the opening area is smaller than the floor brush 23 and the power of the electric blower 18 is reduced. The control means 37 can discriminate from the time of cleaning using a suction port body such as a vine port, and the input of the electric blower 18 can be set more appropriately.

  In the first embodiment and the third embodiment, the floor brush 23 may include the rotary brush 51 and the electric motor 52 of the second embodiment, but the electric motor 52 (the rotary brush 51) It is assumed that the electric blower 18 is controlled independently.

  Next, a fourth embodiment will be described with reference to FIGS. In addition, about the structure and effect | action similar to said each embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  As shown in FIG. 14, the fourth embodiment includes the ground detection means 55 of the third embodiment in the second embodiment.

  Then, with reference to the matrix shown in FIG. 15 and the flowchart shown in FIG. 16, when it is determined in step 21 that the floor brush 23 is not grounded, for example, the amount of dust on the surface to be cleaned is small and used. The control means 37 assumes the phase of the input of the electric blower 18 set by the TRIAC Tr1, assuming that the person is leaving the air passage forming body 13 while the floor brush 23 is floating above the surface to be cleaned. When the angle is set to the first value for the electric blower, the electric blower 18 is operated with the first electric blower input (power 1), and the phase angle of the input of the electric motor 52 set by the triac Tr2 is set to 0. The brush 51 is stopped (step 41).

  Further, when it is determined in step 21 that the floor brush 23 is grounded, the control means 37 is, for example, a cleaning state where the floor brush 23 is grounded to the surface to be cleaned and pressed against the wall with a small amount of dust, etc. Assuming that, the control means 37 operates the electric blower 18 with the second electric blower input (power 2) with the phase angle of the input of the electric blower 18 set by the triac Tr1 as the second value for the electric blower. At the same time, by setting the phase angle of the input of the motor 52 set by the triac Tr2 as the second value for the motor, and operating the motor 52 with the second motor input, the rotary brush 51 is moved to the second rotational speed (the rotational speed 2). ) (Step 42).

  Similarly, when it is determined in step 24 that the floor brush 23 is not grounded, the control means 37 suspends the floor brush 23 (and the extension tube 22), for example, although the amount of dust on the surface to be cleaned is small. Assuming a cleaning state in which another suction port body such as a mouth is used for cleaning, the control means 37 sets the input phase angle of the electric blower 18 set by the triac Tr1 as the second value for the electric blower. Then, the electric blower 18 is operated with the second electric blower input (power 2), and the phase angle of the input of the electric motor 52 set by the triac Tr2 is set to 0, and the electric motor 52, that is, the rotating brush 51 is stopped (step 43).

  Further, when it is determined in step 24 that the floor brush 23 is grounded, the control means 37 performs cleaning by grounding the floor brush 23 on the surface to be cleaned although the amount of dust on the surface to be cleaned is small, for example. Assuming a cleaning state, the control means 37 sets the phase angle of the input of the electric blower 18 set by the triac Tr1 as the third value for the electric blower, and makes the electric blower 18 the third electric blower input (power 3). And the phase angle of the input of the motor 52 set by the triac Tr2 is set to the third value for the motor, and the motor 52 is operated with the third motor input, whereby the rotary brush 51 is moved to the third rotational speed ( It is rotated at a rotation speed 3) (step 44).

  Further, when it is determined in step 27 that the floor brush 23 is not grounded, the control means 37 can remove the floor brush 23 in a narrow place such as a gap between the furniture and the wall, for example. The control means 37 is set by the triac Tr1, assuming a cleaning state in which the suction port body is stationary and cleaned for a predetermined time in order to connect the suction port body and suck in the dust accumulated by the suction air volume. The phase angle of the input of the electric blower 18 is set as the third value for the electric blower, and the electric blower 18 is operated by the third electric blower input (power 3), and the phase angle of the input of the electric motor 52 set by the triac Tr2 is set. As 0, the electric motor 52, that is, the rotating brush 51 is stopped (step 45).

  Further, when it is determined in step 27 that the floor brush 23 is grounded, the control means 37 assumes that the floor brush 23 is cleaning the corner of the surface to be cleaned or near the wall, for example. The control means 37 operates the electric blower 18 with the fourth electric blower input (power 4) with the phase angle of the input of the electric blower 18 set by the triac Tr1 as the fourth value for the electric blower, and the triac Tr2 The rotational phase of the rotary brush 51 is rotated at the fourth rotational speed (revolution speed 4) by setting the phase angle of the input of the motor 52 to the fourth value for the motor and operating the motor 52 with the fourth motor input. (Step 46).

  When it is determined in step 30 that the floor brush 23 is not grounded, the control means 37 applies, for example, the floor brush 23 (and the extension pipe) to a wide range of surfaces to be cleaned such as a shelf with a large amount of dust. 22) and the control means 37 sets the phase angle of the input of the electric blower 18 set by the triac Tr1 to the above-mentioned electric motor. As the fourth value for the blower, the electric blower 18 is operated by the fourth electric blower input (power 4) and the phase angle of the input of the electric motor 52 set by the triac Tr2 is set to 0, and the electric motor 52, that is, the rotating brush 51 is stopped. (Step 47).

  Further, when it is determined in step 30 that the floor brush 23 is grounded, the control means 37, for example, has a large amount of dust on the surface to be cleaned, and the user grounds the floor brush 23 and moves back and forth as usual. Assuming a cleaning state in which the floor brush 23 is reciprocated, the control means 37 sets the phase angle of the input of the electric blower 18 set by the triac Tr1 as the fifth value for the electric blower. The blower 18 is operated with the fifth electric blower input (power 5), and the phase angle of the input of the motor 52 set by the triac Tr2 is a predetermined fifth value for the motor which is a maximum value larger than the fourth value for the motor. As described above, by operating the motor 52 with a predetermined fifth motor input which is a maximum input larger than the fourth motor input, the rotary brush 51 is operated with a predetermined fifth rotation which is a maximum rotation speed larger than the fourth rotation speed. Rotating at (rotation speed 5) (step 48).

  In this way, the grounding state (connection state) of the suction inlet body such as the floor brush 23 or the sill mouth is detected by the grounding detection means 55, and the control unit 37 detects the amount of dust detected by the optical sensor 33 and the motion detection means 45. The operation of the electric blower 18 and the electric motor 52 (the rotating brush 51) is controlled in accordance with the operation of the hand operating unit 27 detected by the above and the grounding state (connection state) of the suction port body detected by the grounding detection means 55. Therefore, it becomes possible to assume the cleaning state of the user with higher accuracy, and the cleaning can be performed with electric power more suitable for the cleaning state, and further energy saving can be achieved. That is, for example, when the floor brush 23 is grounded (connected), the input (power) of the electric blower 18 is increased more than when the floor brush 23 is not grounded (not connected). For example, when cleaning the surface to be cleaned such as the floor surface using the floor brush 23 that requires power, the suction mouth body such as a vine mouth, etc., which requires less power than the floor brush 23. The control means 37 can discriminate from the time of cleaning using the, and the input of the electric blower 18 can be set more appropriately. Moreover, since the electric motor 52 (the rotating brush 51) is stopped when the grounding detecting means 55 detects that the floor brush 23 is not grounded (not connected), unnecessary power consumption is suppressed, and further energy saving is achieved. It becomes possible.

  Next, a fifth embodiment will be described with reference to FIGS. In addition, about the structure and effect | action similar to said each embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  The fifth embodiment basically has the same configuration as that of the fourth embodiment, but the control by the control means 37 is different from that of the fourth embodiment.

  Specifically, in the fifth embodiment, the following controls in steps 51 to 54 are performed instead of the controls in steps 45 to 48 in the fourth embodiment.

  That is, with reference to the matrix shown in FIG. 17 and the flowchart shown in FIG. 18, when it is determined in step 27 that the floor brush 23 is not grounded, the control means 37, for example, the gap between the furniture and the wall, etc. For example, remove the floor brush 23 and connect another suction port body, such as a sill mouth, in a narrow space, and clean the suction port body for a predetermined period of time in order to suck in dust that has accumulated due to the amount of suction air. Assuming a cleaning state, the control means 37 sets the phase angle of the input of the electric blower 18 set by the triac Tr1 as the fifth value for the electric blower, and sets the electric blower 18 to the fifth electric blower input (power 4). And the phase angle of the input of the electric motor 52 set by the triac Tr2 is set to 0, and the electric motor 52, that is, the rotating brush 51 is stopped (step 51).

  Further, when it is determined in step 27 that the floor brush 23 is grounded, the control means 37 causes the floor brush 23 to be grounded, for example, at a corner of the surface to be cleaned where the amount of dust is large or a position near the wall. The control means 37 assumes that the phase angle of the input of the electric blower 18 set by the triac Tr1 is the fifth value for the electric blower and sets the electric blower 18 to the first value. The rotary brush is operated by operating with the electric motor 5 input (power 5) and operating the electric motor 52 with the fifth electric motor input by setting the phase angle of the electric motor 52 set by the triac Tr2 as the fifth value for the electric motor. 51 is rotated at the fifth rotation speed (rotation speed 5) (step 52).

  Further, when it is determined in step 30 that the floor brush 23 is not grounded, the control means 37 applies, for example, the floor brush 23 (and the extension pipe) to a wide range of surfaces to be cleaned such as a shelf with a large amount of dust. 22) and the control means 37 sets the phase angle of the input of the electric blower 18 set by the triac Tr1 to the above-mentioned electric motor. As the third value for the blower, the electric blower 18 is operated with the third electric blower input (power 3) and the phase angle of the input of the electric motor 52 set by the triac Tr2 is set to 0, and the electric motor 52, that is, the rotating brush 51 is stopped. (Step 53).

  When it is determined in step 30 that the floor brush 23 is grounded, the control means 37, for example, has a large amount of dust on the surface to be cleaned, and the user grounds the floor brush 23 and moves back and forth as usual. Assuming a cleaning state in which the floor brush 23 is reciprocated, the control means 37 sets the phase angle of the input of the electric blower 18 set by the triac Tr1 as the fourth value for the electric blower. The blower 18 is operated with the fourth electric blower input (power 4), and the phase angle of the input of the electric motor 52 set by the triac Tr2 is set to the fourth value for the electric motor, and the electric motor 52 is operated with the fourth electric motor input. As a result, the rotary brush 51 is rotated at the fourth rotation speed (rotation speed 4) (step 54).

  As described above, when the dust amount detected by the optical sensor 33 is equal to or larger than the predetermined amount and the operation detecting unit 45 detects that the hand operating unit 27 is not operating, for example, the user detects the surface to be cleaned. The control means 37 assumes that the floor or the position such as the corner or the wall is in a cleaning state where the floor brush 23 or a suction mouth such as a vine mouth is used for cleaning. , At least the input of the electric blower 18 is relatively increased, specifically by driving at the maximum input preset according to the type of the vacuum cleaner 11, etc., corresponding to the cleaning state of the user It becomes possible to effectively clean the dust, and usability is improved.

  In addition, the amount of dust detected by the optical sensor 33 is equal to or larger than a predetermined amount, and the operation detecting unit 45 detects that the hand operating unit 27 is not operating, and the ground detecting unit 55 detects that the floor brush 23 is grounded. For example, in a cleaning state in which the user is intensively cleaning the floor brush 23 against the surface to be cleaned, for example, at the corner of the surface to be cleaned or near the wall. The control means 37 assumes that there is a relative increase in the input of the electric motor 52 together with the electric blower 18, specifically, the maximum preset in accordance with the type of the vacuum cleaner 11, etc. By driving each by input, it becomes possible to more effectively clean the dust corresponding to the user's cleaning state, and the usability is further improved.

  That is, in the case where only the operation detection unit 45 is provided, the control unit 37 may reduce the input when it is detected that the hand operation unit 27 is not operating. By providing both 33 and motion detection means 45, the user uses the floor brush 23 or a suction mouth such as a vine mouth for the position of the corner of the surface to be cleaned or near the wall as described above. It can cope even when it is in a cleaning state where it is cleaning intensively. Therefore, the electric blower 18 and / or the electric motor 52 (the rotating brush 51) can be driven with electric power more suitable for the cleaning state, and can be reliably cleaned. In other words, by providing both the optical sensor 33 and the motion detection means 45, the cleaning state can be detected in a complementary manner, and cleaning can be performed effectively.

  Next, a sixth embodiment will be described with reference to FIGS. 19 and 20. In addition, about the structure and effect | action similar to said each embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  The sixth embodiment basically has the same configuration as that of the fourth embodiment, but the control by the control means 37 is different from that of the fourth embodiment.

  Specifically, in the sixth embodiment, the following control in steps 61 through 66 is performed instead of the control in steps 43 through 48 in the fourth embodiment.

  That is, with reference to the matrix shown in FIG. 19 and the flowchart shown in FIG. 20, when it is determined in step 24 that the floor brush 23 is not grounded, for example, dust stuck to the back of the surface to be cleaned such as a sash. For example, when removing the floor brush 23 and connecting another suction port body such as a hanging mouth for cleaning, etc. Then, the phase angle of the input of the electric blower 18 set by the triac Tr1 is set to the fifth value for the electric blower, and the electric blower 18 is operated by the fifth electric blower input (power 4) and the electric motor 52 set by the triac Tr2 Is set to 0, and the electric motor 52, that is, the rotating brush 51 is stopped (step 61).

  Further, when it is determined in step 24 that the floor brush 23 is grounded, the control means 37 moves the floor brush 23 in small increments, for example, dust such as lint entangled on the surface to be cleaned such as a carpet. Assuming the cleaning state to be cleaned, the control means 37 sets the phase angle of the input of the electric blower 18 set by the triac Tr1 as the fifth value for the electric blower, and sets the electric blower 18 to the fifth electric blower input. The power brush 52 is operated at (power 5), and the phase angle of the input of the motor 52 set by the triac Tr2 is set to the fifth value for the motor. Rotate at 5 revolutions (5 revolutions) (step 62).

  Further, when it is determined in step 27 that the floor brush 23 is not grounded, the control means 37 can remove the floor brush 23 in a narrow place such as a gap between the furniture and the wall, for example. The control means 37 is set by the triac Tr1, assuming a cleaning state in which the suction port body is stationary and cleaned for a predetermined time in order to connect the suction port body and suck in the dust accumulated by the suction air volume. The phase angle of the input of the electric blower 18 is set as the second value for the electric blower, and the electric blower 18 is operated by the second electric blower input (power 2), and the phase angle of the input of the electric motor 52 set by the triac Tr2 is set. As 0, the electric motor 52, that is, the rotating brush 51 is stopped (step 63).

  Further, when it is determined in step 27 that the floor brush 23 is grounded, the control means 37 assumes that the floor brush 23 is cleaning the corner of the surface to be cleaned or the wall side, for example. The control means 37 sets the phase angle of the input of the electric blower 18 set by the triac Tr1 as the third value for the electric blower, operates the electric blower 18 with the third electric blower input (power 3), and also operates the triac Tr2. The rotation angle of the rotary brush 51 is rotated at the third rotation speed (rotation speed 3) by setting the phase angle of the input of the motor 52 set in step S3 as the third value for the motor and operating the motor 52 with the third motor input. (Step 64).

  Further, when it is determined in step 30 that the floor brush 23 is not grounded, the control means 37 applies, for example, the floor brush 23 (and the extension pipe) to a wide range of surfaces to be cleaned such as a shelf with a large amount of dust. 22) and the control means 37 sets the phase angle of the input of the electric blower 18 set by the triac Tr1 to the above-mentioned electric motor. As the third value for the blower, the electric blower 18 is operated with the third electric blower input (power 3) and the phase angle of the input of the electric motor 52 set by the triac Tr2 is set to 0, and the electric motor 52, that is, the rotating brush 51 is stopped. (Step 65).

  Further, when it is determined in step 30 that the floor brush 23 is grounded, the control means 37, for example, has a large amount of dust on the surface to be cleaned, and the user grounds the floor brush 23 and moves back and forth as usual. Assuming a cleaning state in which the floor brush 23 is reciprocated, the control means 37 sets the phase angle of the input of the electric blower 18 set by the triac Tr1 as the fourth value for the electric blower. The blower 18 is operated with the fourth electric blower input (power 4), and the phase angle of the input of the electric motor 52 set by the triac Tr2 is set to the fourth value for the electric motor, and the electric motor 52 is operated with the fourth electric motor input. As a result, the rotating brush 51 is rotated at the fourth rotation speed (rotation speed 4) (step 66).

  Thus, when the control unit 37 detects that the amount of dust detected by the optical sensor 33 is equal to or less than a predetermined amount and the operation detecting unit 45 operates the hand operating unit 27, for example, the user The control means 37 assumes that the dust is entangled with the surface to be cleaned, such as carpets, and the dust, such as thread dust, is being cleaned using the floor brush 23 or the suction port such as the hanging mouth, This control means 37 relatively increases at least the input of the electric blower 18, specifically, by driving the maximum input preset according to the type of the vacuum cleaner 11, etc. The dust can be effectively cleaned in accordance with the state, and the usability is improved.

  In addition, the amount of dust detected by the optical sensor 33 is less than a predetermined amount, and the operation detecting means 45 detects that the hand operating section 27 is operating, and the ground detecting means 55 is connected to the ground of the floor brush 23. For example, the control means 37 indicates that the user is in a cleaning state using the floor brush 23 to clean dust such as lint that is tangled on the surface to be cleaned such as a carpet. Assuming that this control means 37 also relatively increases the input of the electric motor 52 as well as the electric blower 18, specifically, each of them is driven with the maximum input preset according to the type of the vacuum cleaner 11, etc. Thus, it becomes possible to more effectively clean the dust corresponding to the user's cleaning state, and the usability is further improved.

  That is, when only the optical sensor 33 is provided, for example, when cleaning a surface to be cleaned such as a carpet entwined with yarn dust, the amount of dust is determined to be greater than or equal to a predetermined amount because dust is sucked in at an initial stage. In the present embodiment, the optical sensor 33 and the motion detection means 45 may reduce the input because the dust amount is erroneously determined to be equal to or less than a predetermined amount if only the thread waste remains on the surface to be cleaned. By using both of the above, dust such as dust that is difficult for the user to get entangled with the surface to be cleaned, such as carpet, is cleaned using the floor brush 23 or a suction port such as a vine mouth. Even when it is in a cleaning state. Therefore, the electric blower 18 and / or the electric motor 52 (the rotating brush 51) can be driven with electric power more suitable for the cleaning state, and can be reliably cleaned. In other words, by providing both the optical sensor 33 and the motion detection means 45, the cleaning state can be detected in a complementary manner, and cleaning can be performed effectively.

  Note that the control in step 51 of the fifth embodiment and the control in step 61 of the sixth embodiment can be applied even in the case of a configuration that does not include the ground detection means 55 or the floor brush 23, respectively. That is, instead of step 7 of the first embodiment or step 13 of the second embodiment, the control of step 51 of the fifth embodiment may be performed, or the first embodiment may be performed. Instead of step 5 of step 2 or step 12 of the second embodiment, step 61 of the sixth embodiment may be controlled to increase at least the input of the electric blower 18. Further, the control of the fifth embodiment and the control of the sixth embodiment may be combined.

  Then, according to each embodiment described above, the control unit 37 drives at least the electric blower 18 based on the amount of dust detected by the optical sensor 33 and the operation of the hand operation unit 27 detected by the operation detection unit 45. By controlling at least the information from the optical sensor 33 and the information from the motion detection means 45, it is possible to accurately assume the user's cleaning state, and can be cleaned with electric power suitable for the cleaning state, Energy saving is possible.

  In each of the embodiments described above, the hand operating unit 27 is configured to grip and operate the air passage forming body 13, but for example, a so-called upright type electric cleaning in which a floor brush 23 is connected to the lower part of the cleaner body 12. In the case of a machine or the like, the cleaner body 12 may be used for gripping operation.

  In addition, each electric blower input and each electric motor input have been described using common inputs in each embodiment, but different inputs may be used for each embodiment as long as the mutual magnitude relationship is maintained.

  And although some embodiment of this invention was described, these embodiment is shown as an example and is not intending limiting the range of invention.
