Referring to the example of a commercial floor scrubber 100 shown in fig. 1-4, it is designed to be self-moving and self-steering during movement, thereby enabling autonomous cleaning of the floor during movement. The commercial floor scrubber 100, after finishing cleaning, returns to a docking station (not shown) for power replenishment, cleaning fluid (e.g., fresh water) replenishment, sewage removal, etc. The type of commercial floor washer claimed in the present application is not limited to self-moving but may be a manually operated floor washer.
In the present application, the commercial floor washer 100 can be supported above the floor, and the commercial floor washer 100 is designed to move in a main rear-to-front movement direction during operation. All directions mentioned in the examples below are hereby referred to.
In the present application, the machine body 10 of the commercial floor scrubber 100 is designed in three sections, namely, a lower section 101, a middle section 102 and an upper section 103, respectively, and in some embodiments, the heights of the lower section 101, the middle section 102 and the upper section 103 are each approximately 1/3 of the overall height of the commercial floor scrubber 100, and in some embodiments, the height of the middle section 102 is highest, the upper section 103 is next lowest, and the lower section 101 is lowest.
At the lower section 101 there are arranged a moving chassis 2, a wiping device 4 with a wiping tool 41 and a suction shoe 5 with a suction shoe 51. The mobile chassis 2 is intended to be moved over the ground. To control operation, commercial floor washer 100 includes electric cabinet 92 (FIG. 4). The moving chassis 2 includes a chassis frame 20, a pair of front wheels 21, rear wheels 22, and a pair of driving motors 23 mounted at the lower portion of the chassis frame 20. In some embodiments, the pair of front wheels 21 are driving wheels and are driven in rotation by a pair of motors 23, and the rear wheels 22 are driven wheels. In this example, the pair of front wheels 21 has a universal wheel structure, and the drive motor 23 has a hub motor.
The wiping device 4 and the suction rake device 5 can clean the ground, and the wiping device 4 is positioned at the front side of the suction rake device 5. In some embodiments of the application, the wiping tool 41 is a disc brush that can be driven in rotation. In some embodiments, the suction shoe 51 has a circular arc-shaped configuration designed to be able to rest against the ground and to be lifted from the ground. In this example, the water absorbing rake device 5 includes a water absorbing rake bracket 50, a water absorbing rake 51 is supported on the lower part of the water absorbing rake bracket 50, and a supporting wheel 53 is also mounted on the water absorbing rake bracket 50. In operation of the suction rake 5, the support wheel 53 will fall onto the floor to be cleaned and be able to move. When the suction rake 5 is not in operation, the support wheel 53 will be turned back to leave the floor to be cleaned.
At the middle section 102 there is arranged a clean water tank 6 for supplying cleaning liquid (such as water, or an aqueous solution to which a cleaning agent or the like is added) to the wiping tool 41. The middle section 102 also defines an interior cavity 1021. In some embodiments, the internal cavity 1021 is defined by the tank outer wall of the clean water tank 6. The interior cavity 1021 has a rear opening 1022. The middle section 102 is provided with a rear cover 3 at the rear opening 1022.
The rechargeable battery module 9 and the electric cabinet 92 are installed in the inner cavity 1021. The various energy consuming components of the commercial floor washer 100 are electrically connected to the rechargeable battery module 9, and the electric cabinet 92 is capable of transmitting control information to the various controlled components of the floor washer 100. To supplement the rechargeable battery module 9 with electric power, the commercial floor washing machine 100 is also provided with an automatic charging port 91 that can be electrically connected to an external docking station or charger device (not shown). The external docking station or charger device is capable of charging the rechargeable battery module 9 after being electrically connected to the automatic charging port 91.
The rechargeable battery module 9 can be removed from the internal cavity 1021 via the rear opening 1022 when the rear cover 3 is in the open position. The rechargeable battery module 9 is moved out of the machine body, and the rechargeable battery module 9 can be overhauled conveniently.
The commercial floor washing machine 100 is further provided with a sewage tank 7 capable of temporarily storing sewage therein and a suction motor 8 for providing suction of fluid from the suction shoe 51 into the sewage tank 7. The cleaning liquid supplied from the cleaning tank 6 can wet the floor by the wiping tool 41, and the wiping tool 41 can wet-wipe the floor by the cleaning liquid and remove dirt from the floor. The fluid composed of the used cleaning liquid and dirt on the floor is sucked up by the suction rake 51 by means of the suction motor 8 and transferred into the sewage tank 7.
Thus, the commercial floor scrubber 100 is a floor scrubber capable of recovering used cleaning liquid. However, the application is not limited to this type of floor cleaning machine.
For positioning and/or navigating within the surrounding environment, the commercial floor scrubber 100 comprises a navigation device in signal connection with the electric cabinet 92.
