By arranging the clean water tank 1 with the clean water tank, the sewage tank 2 is arranged to recycle sewage and garbage, and the intelligent floor washing machine can continuously and effectively clean the floor.
According to the conception of one embodiment of the invention, the intelligent floor washing machine can execute a self-cleaning and self-cleaning-air drying logic scheme of the rolling brush 4 under the control of the central control system, so that the self-cleaning and self-cleaning-air drying of the rolling brush 4 are realized.
According to the intelligent floor washing machine, after floor cleaning operation is finished, the rolling brush can be cleaned and air-dried automatically at regular or irregular intervals according to the setting of the central control system, so that the cleaning and sanitation of the rolling brush of the floor washing machine can be maintained, and dirt, bacteria breeding, peculiar smell generation and the like of the rolling brush are prevented. Accordingly, the user does not have to manually wash and air-dry or replace the roll brush elements or roll brush material, such as sponge, cloth, etc., on the roll brush/brush tray, thereby freeing up the user's hands and reducing the user's time and material costs.
The self-cleaning, through taking water supply system and sewage recovery system from, the water supply system of intelligent scrubber evenly spouts the clear water in the clear water tank 1 on the round brush component or the round brush material of round brush 4, for example sponge, cloth etc. simultaneously round brush 4 is rotatory with certain rotational speed under the drive of round brush actuating mechanism 5, and rotatory rotational speed and time are enough to utilize centrifugal force to throw away from the round brush material for example most especially most sewage, and suction mechanism 3 synchronous operation forms the negative pressure in sewage recovery passageway, pumps the sewage that is on the round brush 4 in fact most especially has the centrifugal effect to the sewage that throws away into sewage tank 2, accomplishes the cleanness to round brush component or the round brush material of round brush 4.

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 self-cleaning-air drying of rolling brush
According to an exemplary embodiment of the present invention, a roll brush self-cleaning and self-cleaning-air drying control logic scheme of the intelligent floor scrubber is shown in fig. 2.
The rolling brush self-cleaning and self-cleaning-air drying operation of the intelligent floor washing machine comprises a rolling brush cleaning process (or rolling brush self-cleaning process) and a rolling brush air drying process (or rolling brush self-cleaning-air drying process).
More specifically, in the self-cleaning process of the roll brush, water is uniformly sprayed to the roll brush element of the roll brush, such as cloth, by the water supply system to soften and clean the roll brush cloth and dissolve/entrain dirt contained therein, the roll brush is rotated by the drive of the roll brush driving mechanism 5, and the sewage therein is thrown out by centrifugal force to partially enter the sewage recovery passage and is sucked to the sewage tank by the suction mechanism substantially simultaneously, so as to achieve the purpose of cleaning the roll brush cloth. When self-cleaning is completed, 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 throw out water by centrifugal force, and suction can be synchronously carried out through the suction mechanism, so that not only is sewage recovered by suction, but also suction wind force (air flow formed by suction) can be provided by the suction mechanism itself to help evaporation of water in the rolling brush, and self-cleaning-air drying of the rolling brush is promoted under the double action.
The clean water in the clean water tank 1 is uniformly sprayed on the roll brush element, such as cloth, of the roll brush 4 by the water supply system. At the same time, the rolling brush 4 is driven by the rolling brush driving mechanism 5 to rotate at a first rotating speed and a rotating time which are enough to throw out a substantial majority of sewage from 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, and sucking sewage on the roller brush 4, on the floor, and/or centrifugally thrown into the sewage tank 2.
Then, the water supply system of the intelligent floor washing machine can be closed, and the next process can be carried out according to the control logic set by the central control system of the intelligent floor washing machine: the rolling brush 4 is controlled by the central control system and driven by the rolling brush driving mechanism 5 to rotate at a second rotating speed for centrifugal water throwing; in substantial synchronism therewith, the suction means 3 operates in a second gear to suck the sewage on the roller brush 4 and centrifuged out into the sewage tank 2. In order to achieve a better centrifugal water-throwing effect, the second rotational speed may be greater than the first rotational speed described above. 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 rotation at the second rotational speed, a substantial majority of the water on the roller brush 4 has been spun. Subsequently, the water supply system can be kept closed, and the rolling brush 4 can be selectively driven by the central control system and the rolling brush driving mechanism 5 to rotate at a third rotating speed; the suction mechanism 3 continues to suction in the third gear substantially in synchronization with the operation, and after a set period of operation, the roll brush driving mechanism 5 and the suction mechanism 3 are turned off, completing the roll brush self-cleaning-air drying. At this time, the intelligent floor washer may enter a standby state or a floor washing mode.
After the above-described procedure in which the brush 4 is rotated at the first rotational speed or the second rotational speed, since most of the water has been spin-dried, the weight of the brush 4 is smaller, and thus the load at the time of centrifugal rotation operation is smaller, so that the rotation of the brush at a higher rotational speed becomes possible. In order to achieve a better centrifugal water-throwing and air-drying effect, the third rotational speed may be greater than the above-mentioned second rotational speed. At this time, the suction power of the suction mechanism 3, such as a blower, in the third gear operation may be greater than that of the second gear, so that the suction wind speed of the blower is higher, further enhancing the air-drying effect.
In this self-cleaning procedure of the roller brush and self-cleaning-air-drying procedure of the roller brush, the operating parameters in the first to third gear, such as the rotational speed and the operating time, etc., may be parameters preset in the central control system.
Of course, it is well 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 conditions of the self-cleaning and self-cleaning-air-drying of the roller brush, for example, the data of the self-cleaning and self-cleaning-air-drying are detected by the sensor. For example, a roll brush self-cleaning status detection is also included. Whether self-cleaning is completed can be evaluated and judged by providing, for example, a conductive pen in the sewage recovery passage 6, by measuring the conductivity of water (in general, the more dirty water is higher in conductivity), and comparing with the set water conductivity.
The operation flow of the first to third gear may be adjusted or changed according to the setting of the intelligent floor washing machine. For example, after the roll brush cleaning process is completed for a first time, the water supply system may be turned off and the roll brush air drying process may be directly entered.
After the air drying process of the rolling brush is finished for the second time, the floor washing machine can enter a standby state or a floor washing mode immediately.
The roll brush self-cleaning and self-cleaning-air-drying logic scheme according to an exemplary embodiment of the present invention may further include roll brush air-drying status detection. Whether air drying is completed can be evaluated and judged by providing a gravity sensor or other type of weighing 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 roll brush air drying process after the second time may further include: the instant weight of the roller brush 4 is detected. When the weight is lower than a second preset standard, the rolling brush air drying process is finished; when the weight is not lower than the second preset standard, the rolling brush air drying process continues for a fifth time, and the step of detecting the instant weight of the rolling brush 4 is returned.
The roll brush air drying process after continuously lasting the second time and the third time can further comprise: the instant weight of the roller 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, the rolling brush air drying process continues for a sixth time, and the step of detecting the instant weight of the rolling brush 4 is returned.
The invention also discloses a self-cleaning air drying device for the rolling brush, which is used for realizing the self-cleaning and self-cleaning-air drying logic scheme of the rolling brush in any embodiment.
