Wherein the clean water stored in the clean water tank 1 flows through the pump body and is sprayed on the rolling brush element such as cloth of the floor washing rolling brush 4, the rolling brush element such as cloth wetted by the clean water cleans the floor in a manner of mopping or scrubbing for example during the rolling cleaning process of the intelligent floor washing machine, the sewage formed after cleaning the floor is thrown out due to the rotary centrifugal effect of the rolling brush, and is recycled into the sewage tank 2 under the suction effect of the suction mechanism 3 such as a fan together with the other sewage on the floor and on the rolling brush 4, the gas in the mixed air flow entering the sewage tank 2 is discharged through the suction mechanism 3, and the sucked and entrained sewage exists in the sewage tank 2 under the obstruction of the water baffle 8 so as not to cause the fault or damage of the suction mechanism 3 when the water enters the suction mechanism 3.
Self-cleaning and drying roller brush
According to an exemplary embodiment of the present invention, a roll brush self-cleaning-drying control scheme of the intelligent floor washer is shown in fig. 2.
The rolling brush self-cleaning-drying operation of the intelligent floor washing machine comprises a rolling brush cleaning process (or rolling brush self-cleaning process) and a rolling brush drying process (or rolling brush self-drying process).
More specifically, in the self-cleaning process of the rolling brush, water can be uniformly sprayed to the rolling brush element of the rolling brush such as cloth by a water supply system (of course, the intelligent floor washer can just complete the floor washing operation and can also be set without water supply), so as to soften and clean the rolling brush cloth and dissolve/entrain dirt contained therein, the rolling brush rotates under the drive of the rolling brush driving mechanism 5, the sewage is thrown out by centrifugal force and partially enters the sewage recovery channel, and the sewage is pumped to the sewage tank by a pumping mechanism in a substantially synchronous manner, so that the aim of cleaning the rolling brush cloth is achieved. After the self-cleaning is finished, the water supply system can be closed, the rolling brush is driven by the rolling brush driving mechanism 5 to rotate so as to further centrifugally throw out water, and the water can be synchronously sucked through the suction mechanism to help suck and recycle sewage.
During self-cleaning, as shown in fig. 2 and 7, the central control system controls the intelligent floor washer to run back to the recharging seat 40, to climb up the platform 44 via the ramp 41 to park, and to rest with its rollers in the pockets 46, thereby keeping the intelligent floor washer parked, with the roller brush drying heating element 42 aligned with the roller brush 4 directly above it, as shown in fig. 7; and, the central control system controls the rolling brush driving mechanism 5 to drive the rolling brush 4 to rotate at a first rotating speed and a rotating time which are enough to throw a substantial majority of sewage out of the cloth by utilizing centrifugal force; in substantial synchronization therewith, the suction means 3 (e.g. fan, etc.) operates in a first gear, creating a negative pressure in the sewage recovery channel, sucking sewage into the sewage tank 2 for self-cleaning.
Fig. 3 schematically shows a schematic view of a roll brush self-cleaning assembly according to an exemplary embodiment of the invention. Fig. 4 schematically shows a cross-section of a roll brush self-cleaning assembly.
According to an embodiment, the roll brush self-cleaning assembly may comprise: clear water tank 1, sewage case 2, round brush 4, round brush actuating mechanism 5, suction mechanism 3 and well accuse system. The clean water tank 1 is configured to supply clean water to the roll brush 4 via a water supply passage. The suction mechanism 3 may be configured to suck the sewage of the roll brush 4 and the ground to the sewage tank 2 via the sewage recovery passage 6. The central control system may be configured to execute a roll brush self-cleaning logic scheme to control the intelligent floor washer to achieve self-cleaning of the roll brush 4.
The suction means 3 may be in communication with the sewage tank 2 via a suction means airflow channel 7 and may be provided with a water deflector 8 within the sewage tank 2 near or at the inlet of the suction means airflow channel 7.
The roll brush self-cleaning assembly may further comprise a water pump 9, the fresh water being supplied to the roll brush 4 via the water supply path by the water pump 9. The roll brush self-cleaning assembly may further comprise a sprinkling part 10, to which sprinkling part 10 the fresh water may be connected via a water pump 9 and a hose, the sprinkling part 10 sprinkling the water towards the roll brush 4. The roll brush self-cleaning assembly may also comprise a shield 11, for example transparent, provided in the upper half of the roll brush 4.
When the intelligent floor washing machine is used for washing the floor, the water outlet of the clean water tank 1 is connected with the water inlet of the water pump 9 through the hose, and then the water outlet of the water pump 9 is connected with the sprinkling part 10 through the hose. The rolling brush 4 can be composed of soft fur and hard glue and rotate clockwise, the upper periphery of the rolling brush 4 can be covered by a protective cover 11, such as a transparent protective cover, wherein a slightly larger gap can be arranged at the area A of the lower side of the rolling brush 4 corresponding to the inlet of the sewage recovery channel 6, so that air flow can conveniently flow into sewage to be brought in, and the gap is smaller than the gap at the area B of the lower side of the rolling brush 4 opposite to the air flow, so that the area A can be guaranteed to have enough wind force to absorb sewage, and the sewage is sucked into the sewage recovery channel 6.
When the rolling brush 4 performs self-cleaning work, the rolling brush 4 is subjected to sprinkling wetting, softening and cleaning of cloth on the surface of the rolling brush, the rolling brush 4 is driven by the rolling brush driving mechanism 5 to rotate at a higher rotating speed under the control of the central control system, centrifugal water throwing is performed, meanwhile, the fan can perform suction at different gears, negative pressure and suction airflow are generated, and self-cleaning is performed.
After the intelligent floor sweeper is self-cleaned for a period of time, a water supply system of the intelligent floor washer can be closed, and a rolling brush drying process can be started according to control logic set by a central control system of the intelligent floor washer.
Before describing the roller brush drying process in detail, an exemplary recharging seat for an intelligent floor washer and a roller brush heating and drying arrangement thereof according to the present invention will be described with reference to fig. 5 to 7.
As shown in fig. 5-6, a schematic diagram of a recharging station (or "charging station", "charging dock", "base station") 40 for an intelligent floor washer according to an exemplary embodiment of the present invention is shown, which is provided with a design for a drying roller brush 4, including a heating mechanism for roller brush drying. Thus, the recharging stand 40 not only has the function of recharging the intelligent floor washing machine in the conventional art, but also has the function of drying the rolling brush by additionally providing the heating mechanism 42 for drying the rolling brush.
The recharging stand 40 includes a base 48, and a stand 47 mounted on the base 48 to extend vertically upward. The stand 47 may be a separate member from the base 48 or may be integral therewith. In one aspect, the stand 47 may serve the role of a "control cabinet" providing power supply arrangement and circuit configuration for the intelligent floor scrubber, as well as other ancillary features, such as a charging port 49. On the other hand, according to this example, it is also possible to design the storage chamber 45 optionally in the upper part of the stand 47, for example for storing parts and spare parts for maintenance of the intelligent floor scrubber, for example roll brush parts, etc.
The base 48 is designed to facilitate parking the intelligent floor washer for charging and roller brush drying. For example, as shown, the base 48 is designed with a ramp 41 to facilitate the intelligent floor washer climbing up, and a landing 44 for the intelligent floor washer to park in that smooth transition with the ramp 41. To facilitate accurate alignment and position fixing during charging and roller brush drying, the platform 44 is also provided with pockets 46 (typically 2 or 3, and adapted to the number of rollers) adapted to the number and shape of the rollers of the intelligent floor washer, to facilitate parking and holding the rollers during charging and roller brush drying.
Furthermore, it is important that a recess 43 for arranging a heating element 42 for the roll brush drying, for example PTC heating ceramic, is provided on the base 48 at a position corresponding to the roll brush position when the intelligent floor scrubber is parked. In general, the recess 43 is designed such that the position of the roller brush when the intelligent floor scrubber is parked is located directly above the recess 43 and its shape and size also substantially match the shape of the roller brush, e.g. the roller brush is generally elongate, then the recess 43 is also shaped as a substantially corresponding elongate channel. The recess 43 may in another alternative be configured with the additional function of storing and collecting the roll brush sewage.
The heating element 42 may be, for example, a heating tube, a heating fuse, an infrared heating lamp, an ultraviolet lamp, a PTC heating element such as PTC ceramic, a constant temperature heating PTC thermistor. The PTC heating element is preferable because it has the characteristics of constant temperature heating, no open flame, power saving and safety, and the situation that the roller brush is roasted due to the too high heating temperature does not occur.
The following describes the roll brush drying process in detail.
After the roll brush completes the self-cleaning process, the intelligent floor washer is now located at the recharging station 40, as shown in fig. 7. During the roll brush drying procedure, the roll brush driving mechanism 5 is controlled by the central control system to drive the roll brush 4 to rotate at the second rotating speed.
The suction means 3, for example a fan, can be operated in the second gear to suction substantially synchronously with the rotation of the roller brush 4. The second rotational speed is generally greater than the first rotational speed, preferably substantially greater than the first rotational speed, e.g. approaching or reaching full speed of the roll brush.
Thereafter, the heating element 42 for roller brush drying is energized to heat and dry the roller brush 4. As shown in fig. 2, during drying, the blower 3 and the roller brush 4 are turned off and are not operated.
However, as an alternative, in order to facilitate uniform heating and drying of the roller brush 4 by the heating element 42, the central control system may control the roller brush 4 to rotate at a third rotational speed during heating and drying, which is typically set to be much smaller than the first and second rotational speeds, for example, in the range of 10-60 revolutions per minute.
In addition, it is further optional that, in order to accelerate the drying, the blower 3 operates in a third gear for suction, substantially in synchronism with the rotation of the third rotational speed of the roller brush 4. The power of the third gear is typically set to be less than the power of the first gear and the second position.
In order to achieve a faster drying effect, the suction power of the third gear can be set to be larger than that of the first gear, so that the suction wind speed of the fan is higher, and the effect of taking away water vapor and assisting in drying by wind power evaporation is better.
After the heating element 42 heats the roller brush 4 rotated at the third rotation speed for a set period of time, or after sensing that the roller brush 4 has been substantially dried by the sensing means, the roller brush driving mechanism 5 and the suction mechanism 3 are turned off, and the self-drying of the roller brush is completed. At this time, the intelligent floor washer can enter a standby state or enter a floor washing mode or enter a charging mode.
According to a specific setting, the central control system can control the intelligent floor washing machine to perform charging operation during, before and after the intelligent floor washing machine performs the drying program.
In the drying process, the first, second and third rotational speeds and the running time, and the running parameters in the first, second and third gear, for example, rotational speeds and running times, etc., may be parameters preset in the central control system. Of course, it is fully understood by those skilled in the art that the real-time adjustment/setting can also be performed by the central control system based on the detected condition of the roller brush drying, for example, the data of the drying detected by the sensor.
The roll brush self-cleaning-drying logic scheme according to an exemplary embodiment of the present invention may further include roll brush drying status detection. The weight of the roller brush 4 may be monitored by providing a gravity sensor or other type of weight measuring device on the roller brush 4 and compared with a set weight of the roller brush 4 to evaluate and determine whether drying is completed. Of course, it is possible to detect whether the drying is completed in other alternative ways.
Through the self-cleaning-stoving of round brush, can reduce artificial operation, real liberation user's both hands can reduce user's time cost and material cost simultaneously to reach the purpose that prevents the round brush and smell, breeds bacterium and gathering worm such as cockroach, liberation user's both hands simultaneously, reduce user's time cost and material cost.
The foregoing description of several embodiments of the invention has been presented for the purposes of illustration. The foregoing description is not intended to be exhaustive or to limit the invention to the precise features and/or forms disclosed.
Obviously many modifications and variations are possible in light of the above teachings, and are within the scope of the invention. The scope of the invention is limited only by the appended claims.
