TECHNICAL FIELD OF THE INVENTION
The present invention relates to a floor cleaning machine capable of cleaning a floor by rotating a roll-shaped cleaning brush, and more specifically, to a floor in a narrow place such as under a desk. However, the present invention relates to a floor cleaning / cleaning machine devised so that it can be easily and reliably cleaned.
[0002]
[Prior art]
Conventionally used upright floor cleaning machines include a washing water tank provided on the upper side of a brush case, as disclosed in, for example, Japanese Patent Application Laid-Open No. 62-253020. For example, as disclosed in Japanese Patent Application Laid-Open No. 58-209329 and Japanese Patent No. 2650851, a tank in which a washing water tank is attached to an operation handle exists, and is described in the first publication. The `` floor cleaner '' brushes the floor while dropping the washing water contained in the tank on the lower brush side, collects the washing sewage generated by brushing in the above tank, and passes it through the net The refuse is separated and used again as washing water.
[0003]
Further, the "cleaning apparatus for carpets" described in the second publication is devised so that the cleaning liquid does not flow out from the tank attached to the operation handle even if the cleaning apparatus is knocked down during use. Further, the above-mentioned third publication describes a vacuum cleaner having an operation handle provided with two tanks, a washing water tank and a recovery sewage tank.
[0004]
[Problems to be solved by the invention]
However, in the "floor cleaner" described in the above-mentioned first publication, since the tank for storing the cleaning water is provided on the brush case, the height of the entire brush portion from the floor surface is increased. In the case of cleaning a place with a low vertical height such as under a desk or a work table, there is a disadvantage that a brush does not enter and cleaning cannot be performed. The `` cleaning device for carpets '' is a device that cleans the carpet surface by spraying the cleaning liquid from the nozzle with a vigorous nozzle. It is not like a floor cleaning machine that cleans the floor while rotating the cleaning brush. On the other hand, when this is used as it is as a floor cleaning machine, there is a problem that the floor cannot be sufficiently cleaned.
[0005]
Further, the "vacuum cleaner" described in the third publication has a heater, a steam generator, or water in addition to two tanks of a washing water storage tank and a contaminated water storage tank on an operation handle. Since a large number of various devices such as a supply device are attached, the whole becomes large and heavy, and there is a problem that cleaning in a narrow place such as under a desk becomes extremely difficult. .
[0006]
Therefore, a technical problem of the present invention is to make a brush case containing a cleaning brush as low as possible so as to easily perform cleaning on a floor surface where there is not enough space on an upper surface side such as under a desk or a shelf. And the cleaning water can be supplied uniformly over the entire length of the cleaning brush without leaking out of the brush case, and the structure of the cleaning and water absorbing portion can be made relatively simply and at low cost. It is an object of the present invention to provide a floor cleaning and cleaning machine that is devised so as to be able to perform the cleaning.

Since excess air is smoothly sucked into the washing water tank 3 side without sucking through the chamber 30, the generation of bubbles can be reduced, and the washing sewage can be efficiently sucked.
[0053]
Further, in the present invention, since the front squeegee blade 15 is configured to be detachable from the squeegee holder 24 provided on the front surface of the brush case 11, replacement and maintenance of the squeegee blade 15 can be easily performed. At the same time, since the squeegee holder 24 itself functions as a bumper, there is no fear that the brush case 11 may be damaged or damaged even if the brush case 11 collides with a wall or the like at the time of cleaning. Further, since the squeegee blade 15 held by the squeegee holder 24 is prevented from laterally moving (displaced) by the engagement of the engagement projection 24T and the engagement hole 15B, the cleaning operation can proceed without any trouble. .
