Self-cleaning and self-drying of rolling brush

According to an exemplary embodiment of the present invention, a logic scheme of the roll brush self-cleaning and self-drying control of the intelligent floor washing machine is shown in fig. 2.

The rolling brush self-cleaning and self-air-drying operation of the intelligent floor washing machine comprises a rolling brush cleaning process (or called rolling brush self-cleaning program) and a rolling brush air-drying process (or called rolling brush self-air-drying program).

More specifically, in the roll brush self-cleaning process, water is uniformly sprayed to a roll brush element of the roll brush, such as a cloth, through a water supply system to soften and clean the cloth of the roll brush and dissolve/entrain dirt contained therein, the roll brush is driven by a roll brush driving mechanism 5 to rotate, sewage is thrown out of the roll brush driving mechanism by centrifugal force to partially enter a sewage recovery channel, and is substantially synchronously sucked to a sewage tank through a suction mechanism, so that the aim of cleaning the cloth of the roll brush is fulfilled. After the self-cleaning is completed, the water supply system can be closed, the rolling brush can rotate under the drive of the rolling brush driving mechanism 5 to further throw out water by centrifugal force, and can synchronously suck through the suction mechanism, so that sewage is sucked and recovered, and the suction mechanism can provide suction wind force (air flow formed by suction) to help the evaporation of water in the rolling brush, thereby promoting the self-drying of the rolling brush under the double actions.

The clean water in the clean water tank 1 is uniformly sprayed on the roll brush elements, such as cloth, of the roll brush 4 by a water supply system. Substantially simultaneously with the fresh water spraying operation, the roller brush 4 is rotated by the roller brush drive mechanism 5 at a first rotational speed and for a time sufficient to throw a substantial majority of the contaminated water from the cloth by centrifugal force; substantially simultaneously therewith, the suction means 3 (e.g. fan, etc.) is operated in the first gear, creating a negative pressure in the waste-water recovery channel, while the waste water on the roller brush 4, on the floor and/or thrown off centrifugally is sucked into the waste-water tank 2.

And then, the water supply system of the intelligent floor washing machine can be closed, and the next flow can be entered according to the control logic set by the central control system of the intelligent floor washing machine: the rolling brush 4 rotates at a second rotating speed under the control of the central control system and the driving of the rolling brush driving mechanism 5 to carry out centrifugal water throwing; substantially synchronously therewith, the suction mechanism 3 operates in the second gear for suction to suck the sewage on the roll brush 4 and centrifugally thrown out into the sewage tank 2. In order to achieve a better centrifugal water throwing effect, the second rotating speed can be larger than the first rotating speed. The rotation operation time at the second rotation speed may be longer than the rotation time at the first rotation speed.

After a set period of time of the rotational operation at the second rotational speed, a substantial majority of the water of the drum brush 4 has been dried. Subsequently, the water supply system can be kept closed, and the rolling brush 4 can be selectively rotated at a third rotating speed under the control of the central control system and the driving of the rolling brush driving mechanism 5; the suction mechanism 3 works at a third gear to continue sucking in a mode of being approximately synchronous with the first gear, and the rolling brush driving mechanism 5 and the suction mechanism 3 are closed after the rolling brush driving mechanism operates for a set period of time, so that the self-drying of the rolling brush is completed. At this time, the intelligent floor washing machine can enter a standby state or enter a floor washing mode.

After the above-described procedure in which the drum brush 4 is rotated at the first rotation speed or the second rotation speed, since most of the water has been dried, the weight of the drum brush 4 is smaller, and thus the load at the time of the centrifugal rotation operation is smaller, so that the rotation of the drum brush at the higher rotation speed becomes possible. In order to achieve a better centrifugal water-slinging and air-drying effect, the third rotation speed can be greater than the second rotation speed. At this time, the suction power of the suction mechanism 3, for example, a fan, operating at the third gear may be greater than the suction power of the second gear, so that the suction wind speed of the fan is higher, and the air drying effect is further enhanced.

In this rolling brush self-cleaning routine and rolling brush self-drying routine, the operating parameters in the first to third gears, such as the rotational speed and the operating time, 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 be performed by the central control system according to the detected self-cleaning and self-drying conditions of the rolling brush, for example, the self-cleaning and self-drying data detected by the sensor. For example, rolling brush self-cleaning state detection is also included. It is possible to evaluate and judge whether or not self-cleaning is completed by providing, for example, a conductive pen in the sewage recovery channel 6, by measuring the conductivity of water (in general, the more dirty water has higher conductivity) and comparing it with the set water conductivity.

The operation flow of the first gear, the second gear and the third gear can be adjusted or changed according to the setting of the intelligent floor washing machine. For example, after the rolling brush cleaning process is continued for the first time, the water supply system can be closed, and the rolling brush air drying process can be directly started.

After the rolling brush air drying process is finished for the second time, the floor washing machine can enter a standby state or a floor washing mode immediately.

According to the utility model discloses a round brush automatically cleaning and from air-dry logic scheme of an exemplary embodiment can still include the round brush air-dry state and detect. Whether the air-drying is completed or not can be evaluated and judged by providing a gravity sensor or other type of weight measuring device on the roll brush 4 to monitor the weight of the roll brush 4 and comparing with the set weight of the roll brush 4.

Of course, it is also possible to detect whether the air-drying is completed in other alternative ways.

For example, the tumbling air-drying process may further include, after the second time: the instant weight of the roll brush 4 is detected. When the weight is lower than a second preset standard, the rolling brush air drying process is finished; and when the weight is not lower than a second preset standard, the rolling brush air drying process continues for a fifth time, and then the step of detecting the instant weight of the rolling brush 4 is returned.

The rolling brushing air drying process may further include, after continuing for the second time plus the third time: the instant weight of the roll brush 4 is detected. When the weight is lower than a third preset standard, the rolling brush air drying process is finished; and when the weight is not lower than a third preset standard, continuing the rolling brush air drying process for the sixth time, and returning to the step of detecting the instant weight of the rolling brush 4.

The utility model also discloses a device is air-dried to round brush automatically cleaning for realize the round brush automatically cleaning and from the air-dried logic scheme in aforementioned arbitrary embodiment.
