2. Description of the Related Art As shown in Japanese Utility Model Laid-Open Publication No. Sho 63-18966, for example, a conventional general floor cleaning machine has a cleaning water tank for storing cleaning water (clear water or detergent liquid) at the upper part of the body. Since two tanks, a sewage tank for collecting squeegee water and collecting the squeegee, are installed, these tanks cannot be made so large in terms of space. The drainage of sewage had to be repeated frequently at relatively short intervals, which was very inconvenient in operation.

Accordingly, the applicant of the present invention has disclosed in Japanese Patent Application Laid-Open No. Hei 2-17792.
As can be seen in Japanese Patent Publication No. 9-209, the tank of the floor washer has a double inner / outer structure in which a flexible and waterproof bag for washing water is accommodated inside the sewage tank. The capacity was substantially doubled, and the washing operation time was extended.

[0004]

However, in the above-mentioned conventional floor washer in which the tank has a double inner / outer structure, the washing water is injected since the inlet (inlet) of the washing water bag is made narrow. For example, it is not possible to put it in a container with a large mouth such as a bucket, and it must be put in using a pump or a hose, etc., so it takes time to inject water and the work efficiency is greatly reduced There is also a problem that the inside of the bag is difficult to clean due to the narrow water inlet.

Further, in the above-mentioned conventional floor washer, since a hose (pipe) of a water supply pump for sending cleaning water to the rotating brush is attached to the bottom of the bag, it is very difficult to process the bag.
In addition, the bottom of the bag to which these hoses or pipes are attached is very susceptible to pain due to repeated bending movements, and if used for a long period of time, this bottom will break and the washing water will leak to the dirty water tank side, In addition, there is a problem that the outside sewage mixes into the inside of the bag and contaminates the washing water, and if the sewage tank water level is rising, if the top lid of the aircraft is carelessly opened, There was also a problem that sewage bubbles or sewage itself adhering to the upper lid scattered outside the tank and soiled the surroundings, and also stained the clothes of the driver.

Therefore, the technical problem of the present invention is that the injection of the washing water can be completed easily and in a short time, the inside can be easily cleaned, the processing of the bag is easy, and the whole bag is durable. It is an object of the present invention to provide a tank device for a floor washer which is constructed so that there is no possibility of leakage due to breakage or contamination of sewage, and that the sewage can be used in a sanitary manner without being scattered around.

[0007]

Means taken by the present invention to solve the above technical problems are as follows. A flexible and waterproof bag for washing water is installed inside the sewage tank for collecting the squeegee-sucked sewage, and the washing water contained in the bag is supplied to the rotating brush to wash the floor. In the floor cleaning machine configured in
