ことになる。2. Description of the Related Art A conventional floor cleaning robot will be described. As shown in FIG. 2 and FIG. 3, a pair of left and right drive wheels 2, a front driven wheel 3 and a rear driven wheel 4 are provided at the center of the lower surface of the trolley 1, and the inside of the water tank placed on the trolley 1 is divided into left and right partition plates. 5 is divided into a fresh water tank 6 and a dirty water tank 7, and a sprinkling pipe (not shown) is led out from the fresh water tank 6 to the vicinity of the brush 8 on the lower surface of the carriage 1, and a suction device 9 for sucking the dirty water on the floor is used as the dirty water. It is connected to the tank 7. A lid body 11 provided with a sealing packing 10 in the opening 7a of only the dirty water tank 7 above the fresh water tank 6 and the dirty water tank 7.
Is covered. When the floor cleaning robot with this configuration is operated, water is sprinkled from the fresh water tank 6 to the floor surface with a sprinkling pipe, the brush 8 is rotated to polish the floor surface, and the dirty water remaining on the floor surface is sucked into the dirty water tank 7 by the suction device. Suction and self-run while cleaning.
Therefore, the fresh water tank 6 is initially full and the dirty water tank 7 is empty, and finally the fresh water tank 6 is empty and the dirty water tank 7 is filled with dirty water. In this case, the center of gravity of the trolley 1 greatly changes with time, and the left and right drive wheels 2 and front driven wheels 3 are moved.
Since the load applied to the rear driven wheel 4 changes, it becomes difficult to maintain the straightness of the floor cleaning robot. There is also a method of arranging the fresh water tank 6 and the dirty water tank 7 in the front and rear, but this increases the front-back movement of the center of gravity and complicates the suspension mechanism corresponding to the change in the load applied to the front and rear driven wheels 3 and 4. It will be.
