DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor cleaning machine for cleaning a floor with a cleaning brush or pad (hereinafter simply referred to as a cleaning brush) rotated at a high speed by a motor. The present invention relates to a structure of tanks for washing water and sewage mounted on a floor washing machine.

[0002]

2. Description of the Related Art Conventional floor cleaning machines include, for example,
As shown in Japanese Utility Model Laid-Open Publication No. Sho 62-23663, etc., a washing water tank for storing washing water at the upper portion of a vehicle body and a sewage tank for storing sewage suctioned and collected by a squeegee are provided side by side or front and rear. On the lower part of the carriage, a motor for rotating the cleaning brush and a battery serving as a power source of the motor are mounted.

[0003]

According to the conventional floor washer constructed as described above, the tank for washing water is provided on the upper part of the body, so that the washing water can be easily supplied. Although it has the advantage that it can be provided, on the other hand, more than half of the space in the upper part of the aircraft is occupied by sewage collection devices such as sewage tanks and suction blowers, and it is not possible to obtain sufficient tank capacity for washing water. Cycle becomes short and the operation becomes complicated.
Further, as described in FIG. 1 of the above publication, since the distance between the washing water tank and the washing brush is vertically different, facilities such as a water supply pipe for surely supplying the washing water to the washing brush are provided. However, there is a problem of complicating the structure.

Further, since a cleaning brush motor and a battery are housed in a narrow space on the lower side of the machine body, it is not possible to secure a working space for these devices, so that maintenance is extremely difficult and the volume of the tank is reduced. However, because there is a lot of wasted space as a whole, the whole body becomes unnecessarily large and tall, making operability and water handling difficult and increasing production costs And so on.

Accordingly, the technical problem of the present invention is to minimize the useless space inside the machine body, to secure the capacity of the washing water tank and the sewage tank as much as possible, and to maintain the cleaning brush and the battery for maintenance. An object of the present invention is to provide a tank device for a floor washer which is devised so that a work space can be ensured and these components can be assembled neatly to make the whole compact and at a relatively low cost. .
