  Preferably, the vacuum cleaner further includes an operation unit connected to the first and second engagement units, and the operation unit operates the lid unit and the dust collecting container in the first and second engagement units. The engagement is released.

  In the vacuum cleaner configured as described above, the dust compressed by the compression unit can be easily discharged out of the dust collecting container by opening the lid. In addition, since the first and second engaging portions are arranged on both sides of the line connecting the rotation mechanism and the center of the lid portion, the lid portion can be reliably pressed against the dust collecting container by the engaging portion. .

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an external view of a vacuum cleaner according to an embodiment of the present invention. First, a schematic configuration of a vacuum cleaner 400 according to an embodiment of the present invention will be described with reference to FIG. As shown in FIG. 1, the vacuum cleaner 400 includes a cleaner main body 410, an air inlet 420, a connection pipe 430, a connection hose 440, an operation handle 450, and the like. The vacuum cleaner main body 410 includes an electric blower, a cyclone dust collector, a control device, and the like that are not shown in FIG.

  The electric blower has a blower fan for performing intake air and a blower drive motor that rotationally drives the blower fan. The control device includes control devices such as a CPU (Central Processing Unit), a RAM (Random Access Memory), and a ROM (Read Only Memory), and comprehensively controls the vacuum cleaner 400. Specifically, in the control device, the CPU executes various processes according to a control program stored in the ROM.

  The operation handle 450 is provided with operation switches for the user to perform operations such as whether or not the vacuum cleaner 400 is operated and an operation mode selection operation. A display unit such as an LED (Light Emitting Diodes) that displays the current state of the vacuum cleaner 400 is also provided in the vicinity of the operation switch.

  The vacuum cleaner main body 410 is connected to the air inlet 420 via a connection hose 440 connected to the front end of the vacuum cleaner main body 410 and a connection pipe 430 connected to the connection hose 440. Therefore, in the electric vacuum cleaner 400, the electric blower incorporated in the cleaner main body 410 is operated, whereby intake from the intake port 420 is performed. Then, the air sucked from the intake port 420 flows into the cyclone dust collector through the connection pipe 430 and the connection hose 440. In the cyclone dust collector, dust is centrifuged from the sucked air. The air after the dust is separated by the cyclone dust collector is exhausted from an exhaust port provided at the rear end of the cleaner body 410.

  Hereinafter, the cyclone dust collector which is an example of the cyclone dust collector which concerns on this invention is demonstrated.

  FIG. 2 is a bottom view of the cyclone dust collector used in the vacuum cleaner according to the embodiment of the present invention. FIG. 3 is a cross-sectional view for explaining the internal structure of the cyclone dust collector along the line III-III in FIG. FIG. 4 is a cross-sectional view for explaining the internal structure of the cyclone dust collector along the line IV-IV in FIG.

  As shown in FIG. 2 to FIG. 4, the cyclone dust collecting apparatus 300 is a dust collecting container 11 (an example of a collecting container) that has a casing 10 and an inner peripheral surface that is substantially cylindrical and is detachable from the casing 10. ), An inner cylinder 12, an upper filter unit 13, a dust receiving portion 14, a dust removal drive mechanism, and the like.

  In the cyclone dust collecting apparatus 300, the dust collecting container 11, the inner cylinder 12, the upper filter unit 13, and the dust receiving unit 14 are coaxially arranged with the vertical central axis P as the center. Moreover, the cyclone dust collector 300 is configured to be detachable from the cleaner body 410.

  The housing 10, which is an example of the upper lid, includes an inner cylinder 12 that includes an inner cylinder filter 122.

  In the cyclone dust collecting apparatus 300, the air in the dust collecting container 11 is exhausted from the inner cylinder 12 provided in the central part of the substantially cylindrical dust collecting container 11, thereby being provided in the inner peripheral part of the dust collecting container 11. After the air sucked from the air inlet 111a is swung along the inner peripheral surface of the dust collecting container 11, it is exhausted through the inner cylinder 12 through the upper filter unit 13 which is an example of the filter means, The relatively large collection target contained is collected at the bottom of the dust collecting container 11, and the relatively small collection target is collected by the upper filter unit 13 or the like.

  The dust collecting container 11 is a container having a cylindrical inner peripheral surface for accommodating dust separated from the sucked air and a cylindrical outer shape. The dust collecting container 11 is configured to be detachable from the casing 10 of the cyclone dust collecting apparatus 300.

  A bottom lid 310 is attached to the bottom of the dust collecting container 11 so as to be openable and closable. FIG. 2 shows a state where the bottom cover 310 is closed. The user removes the dust in the dust collecting container 11 by opening the bottom cover 310 after taking out the cyclone dust collecting device 300 from the cleaner body 410.

  An annular seal member 161 is provided between the casing 10 of the cyclone dust collector 300 and the dust container 11. The seal member 161 can prevent air leakage between the housing 10 and the dust collecting container 11.

  In addition, the bottom cover 310 of the dust collecting container 11 is provided with a fitting portion 11 a that fits into the rotating shaft portion 123 b provided on the inner cylinder 12. An annular seal member 11b for filling a gap with the rotation shaft portion 123b of the inner cylinder 12 is provided on the outer peripheral portion of the fitting portion 11a. The seal member 11b can prevent air leakage between the rotary shaft portion 123b and the dust collecting container 11.

  Furthermore, the dust collection container 11 is provided with a connection portion 111 to which the connection hose 440 is connected. Air sucked from the inlet port 420 through the connecting pipe 430 and the connecting hose 440 flows into the dust collecting container 11 from the connecting part 111.

  The air inlet 111 a of the connecting portion 111 to the dust collecting container 11 is formed so that air from the connection hose 440 swirls within the dust collecting container 11. Specifically, the air inlet 111 a is formed so as to face the tangential direction of the dust collecting container 11, so that the air sucked from the air inlet 111 a swirls along the inner periphery of the dust collecting container 11. To do. Accordingly, the dust contained in the swirling air is pressed against the inner peripheral surface of the dust collecting container 11 by centrifugal force due to the swirling, and therefore, the swirling speed is lost and falls to the bottom of the dust collecting container 11 and separated from the swirling air. (Centrifugation). The dust centrifuged in the dust collection container 11 is accommodated in the bottom of the dust collection container 11.

  On the other hand, the air after the dust is separated is exhausted from the dust collecting container 11 to the outside through the exhaust port provided in the cleaner body 410 along the exhaust path indicated by the arrow 112a. Here, on the exhaust path 112 from the dust collecting container 11 to the exhaust port, the inner cylinder 12, the dust receiving part 14 and the upper filter unit 13 are arranged in order, and relatively fine dust in the airflow is collected in the inner cylinder. 12 and the filter provided in the upper filter unit 13.

  The inner cylinder 12 is a cylindrical member disposed in the dust collection container 11. Here, the inner cylinder 12 is rotatably supported by the dust receiver 14. Specifically, the inner cylinder 12 is configured such that the annular recess 12a provided at the upper end of the inner cylinder 12 is supported by the annular support part 14c provided at the lower end of the dust receiver 14, thereby It is suspended so that it can rotate together. In addition, the structure which supports the inner cylinder 12 rotatably is not restricted to this. For example, it is conceivable as an example to support the upper and lower ends of the inner cylinder 12.

  The inner cylinder 12 is coupled to the inclined dust removing member 134 so as to be integrally rotatable. As a result, the inner cylinder 12 rotates in conjunction with the inclined dust removing member 134. In addition, the connection structure of the inner cylinder 12 and the inclination dust removal member 134 is not restricted to this. For example, the structure connected so that integral rotation is possible by fitting the fitting part provided in each of the inner cylinder 12 and the inclination dust removal member 134 is considered.

  In addition, an inner cylinder exhaust port 121 for exhausting the air after the dust is separated in the dust collecting container 11 toward the upper filter unit 13 is formed in the upper part of the inner cylinder 12. The inner cylinder exhaust port 121 is provided with an inner cylinder filter 122 having an inner cylinder shape that covers the entire inner cylinder exhaust port 121. The inner cylinder filter 122 filters air passing through the inner cylinder exhaust port 121.

  For example, the inner cylinder filter 122 is a mesh-shaped air filter or the like. The inner cylinder filter 122 may be provided either inside or outside the inner cylinder exhaust port 121. Further, instead of the inner cylinder exhaust port 121 and the inner cylinder filter 122, a configuration in which a mesh-like hole is formed in the inner cylinder 12 is also conceivable. In that case, the mesh holes function as the inner cylinder exhaust port 121 and the inner cylinder filter 122.

  In the bottom view shown in FIG. 2, a first engagement portion 520 and a second engagement portion 530 are provided on both sides of a line connecting the rotation mechanism 510 and the bottom lid 310. With such an arrangement, the bottom lid 310 can be reliably fixed to the dust collecting container 11 by the rotation mechanism 510, the first engagement portion 520, and the second engagement portion 530.

  FIG. 5 is a perspective view showing the structure of the cyclone dust collecting apparatus 300 as seen from a certain direction. FIG. 6 is a perspective view showing the structure of the cyclone dust collector 300 viewed from another direction. With reference to FIGS. 5 and 6, the bottom lid 310 is rotatably attached to the dust collecting container 11 by a rotation mechanism 510. The bottom lid 310 seals the opening 330 to prevent dust from leaking from the opening. The bottom lid 310 is held in the dust collecting container 11 by the rotation mechanism 510, the first engagement portion 520, and the second engagement portion 530. By operating the operation unit 540, the first engagement unit 520 and the second engagement unit 530 are disengaged, and the bottom cover 310 rotates about the rotation mechanism 510. Thereby, the opening 330 is exposed and dust can be discharged from the dust collecting container 11.

  FIG. 7 is a perspective view showing a state in which the bottom cover 310 is opened. As shown in FIG. 7, when the engagement between the first engagement portion 520 and the second engagement portion 530 and the bottom lid 310 is released, the bottom lid 310 rotates about the rotation mechanism 510 to open. 330 is exposed. As a result, the dust compressed by the spiral rotary compression unit 123 is discharged from the opening 330.

  FIG. 8 is a perspective view for explaining the configuration of the operation unit 540 provided in the dust collecting container 11 in detail. FIG. 9 is a perspective view showing a state where the operation portion 540 is operated and the engagement by the first engagement portion 520 and the second engagement portion 530 is released. With reference to FIG. 8 and FIG. 9, the operation portion 540 is connected to an arm portion 541 that extends along the outer peripheral surface of the dust collecting container 11. The arm side tip portions 542 and 543 of the arm portion 541 are in contact with the engagement portion side tip portions 521 and 531 provided in the first engagement portion 520 and the second engagement portion 530, and the contact surfaces are tapered. It is considered as a surface. As a result, the arm portion 541 slides in the circumferential direction, so that the engagement portion side tip portions 521 and 531 move in the radial direction. As a result, the first engagement portion 520 and the second engagement portion 530 rotate and the engagement between the first engagement portion 520 and the second engagement portion 530 and the bottom cover 310 is released. The first engagement portion 520 and the second engagement portion 530 are biased by springs 522 and 532.

  FIG. 10 is an enlarged perspective view showing the housing 10 and the helical rotation compression unit 123 attached to the housing 10. FIG. 11 is an exploded perspective view for explaining the internal configuration of the housing 10.

  At the lower part of the inner cylinder 12, there is provided a spiral rotary compression unit 123 that can rotate around a vertical central axis for compressing the dust in the dust collecting container 11. The helical rotation compression unit 123 will be described with reference to FIG. 4 which is a perspective view of the helical rotation compression unit.

  As shown in FIGS. 2 and 3, the spiral rotary compression portion 123 is provided with a spiral portion 123 a having a spiral curved surface, a rotation shaft portion 123 b, and a disk-shaped shielding member 123 c. .

  The rotating shaft portion 123 b is a hollow cylinder that is fitted into a fitting portion 11 a provided at the bottom of the dust collecting container 11. As described above, the seal member 11b is interposed between the rotating shaft portion 123b and the fitting portion 11a.

  The disc-shaped shielding member 123c includes, in the dust collecting container 11, an upper space portion (separation portion 104) that separates dust by a centrifugal centrifugal force and a lower space portion (dust collection portion 105) that accumulates dust. Serves as a partition. Thereby, the collected dust is prevented from rolling up and clogging the inner cylinder filter 122. Moreover, since it is disk shape, the dust contained in a cyclone air current is not caught, and dust can be efficiently guide | induced to the bottom part of the dust collecting container 11. FIG.

  The rotary shaft portion 123b extends in a spiral shape toward the bottom surface of the dust collecting portion 105 with the rotary shaft portion 123b as the center, and the upper and lower surfaces thereof are curved with a spiral curved surface centered on the vertical central axis P. A plate-shaped spiral portion 123a (a part of the compression member) is provided. As will be described later, the spiral portion 123a is a screw that collects dust collected in the dust collecting container 11 when the inner cylinder 12 rotates and has resistance to rotating in contact with the inner peripheral surface of the dust collecting container 11. It is moved toward the bottom of the dust collecting container 11 by the carrying action. At this time, when the spiral curved surface of the compression member is assumed to be a screw, the screw is retracted by rotation of the compression member, so that dust can be compressed by the spiral curved surface.

  At this time, the spiral curved surface of the spiral portion 123a is preferably formed with the same inclination direction as the swirling airflow. By rotating the spiral portion 123a in the direction opposite to the turning, the dust in the dust collecting container 11 moves to the bottom of the dust collecting container 11 due to friction with the inner surface of the dust collecting container 11.

  However, it is also possible to incline the spiral curved surface of the spiral portion 123a in a direction opposite to the inclination of the airflow swirling along the inner peripheral surface of the dust collecting container 11. At this time, the rotation direction of the spiral portion 123a is the same direction as the rotation direction of the swirling airflow, that is, when the spiral portion 123a is assumed to be a screw, the screw is retracted by the rotation of the spiral portion 123a.

  Further, when the inner cylinder 12 rotates, the spiral portion 123a rotates with respect to the dust moving to the bottom of the dust collecting container 11 by rotating the dust with the bottom surface by friction with the bottom of the dust collecting container 11. It will be extruded and compressed from the outside to the outside. With such a configuration, since the dust is firmly compressed by the rotation, the amount of dust that can be accumulated in the dust collecting container 11 can be increased. Therefore, it is possible to reduce the size of the dust collecting container 11. Also, since the hardly compressed dust cannot be easily dissolved, there is no problem of scattering in the air even when it is taken out, and it can be discarded as it is.

  In addition, as described above, a part of the dust compressed by the spiral portion 123a by the rotation of the spiral rotation compression portion 123 of the spiral rotation compression portion 123 includes long hair and the like, and thus entangles with the spiral portion 123a. Therefore, even if the bottom lid 310 is opened as described above and dust is released from the opening 330 formed in the bottom of the dust collecting container 11, it is not easily released to the outside. Further, when dust is released vigorously, fine dust contained in the dust is scattered in the air, and the room is soiled. Therefore, there is a need for a mechanism for slowly releasing dust to the outside by a simple operation by some method. A mechanism for slowly releasing dust provided for that purpose to the outside by a simple operation will be described below.

  A handle 314 is provided on the upper surface of the housing 10 provided with the upper filter unit 13 therein. The handle 314 is an example of an operation member that can be operated from the outside.

  The handle 314 is rotatable around the vertical axis independently of the housing 10. Inside the handle 314, an upper handle built-in gear 316 constituting an inclined surface is integrally built, and a lower handle built-in gear 318 constituting an inclined surface is meshed with the upper handle built-in gear 316. When the upper handle built-in gear 316 rotates, the lower handle built-in gear 318 is pushed downward and moves downward. Therefore, by rotating the handle 314, the upper handle built-in gear 316 meshes with the lower handle built-in gear 318, and the rotation of the handle 314 is transmitted to the lower handle built-in gear 318.

  The lower handle built-in gear 318 is formed on the upper surface of the intermediate body 320, and a clutch gear is formed on the lower surface of the intermediate body 320, so that the intermediate body 320 is moved by the downward movement of the lower handle built-in gear 318. At the same time, the clutch gear moves downward.

  A clutch receiving portion that is integrally fixed to the filter dust removing member 132 through a gap is provided below the intermediate body 320, and the clutch gear and the clutch receiving portion are moved along with the downward movement of the intermediate body 320. And the rotation of the handle 314 is transmitted to the filter dust removing member 132 via the clutch mechanism including the clutch gear and the clutch receiving portion, and the inner cylinder 12 connected to the filter dust removing member 132 and the inner cylinder 12 integrally therewith. The connected spiral rotation compression unit 123 rotates, and the spiral portion 132a rotates. Accordingly, the dust entangled with the spiral portion 123a is slowly conveyed toward the distal end of the spiral portion 123a by the carrying action of the screw of the spiral portion 123a, and from the bottom opening of the dust collecting container 11 opened by opening the bottom lid 310. Released to the outside.

  As the handle 314 is rotated by the operator in this manner, dust is slowly discharged to the outside, so that fine dust contained in the dust is prevented from flying up, and the interior of the room can be prevented without being scattered. It is not contaminated by dust.

  When the hand is released from the handle 314, the intermediate body 320 is pushed up by the spring built in the spring accommodating portion, and the clutch mechanism including the clutch gear and the clutch receiving portion is released. Thus, since the clutch mechanism is in an open state unless the handle 314 is operated, even if the filter dust removing member 132 is rotated by the dust removing drive motor 151, the handle 314 is not rotated, which is safe.

  With reference to these drawings, the second engagement portion 530 has a shaft portion 535 serving as a rotation shaft. The shaft portion 535 has a cylindrical shape and is formed so as to extend along the circumferential direction of the dust collecting container 11. A shaft portion 535 is rotatably held by the dust collecting container 11.

  The engaging portion side end portion 531 protrudes in the extending direction of the shaft portion 535, and a force is applied from the arm portion. In this embodiment, the arm portion 541 is provided to release the engagement between the first engagement portion 520 and the second engagement portion 530 by operating one operation portion 540. If the configuration in which the engagement of the first engagement portion 520 is released and the second operation portion releases the engagement of the second engagement portion 530 is employed, the arm portion 541 is not necessary.

  An engagement end portion 533 is provided at the lower end of the second engagement portion 530. The engagement end portion 533 is shaped to receive the outer peripheral portion of the bottom lid 310, and the second engagement portion 530 rotates about the shaft portion 535, whereby the engagement end portion 533 and the bottom lid 310 are engaged.
