Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technical field of a floor cleaning machine (scrubber) for cleaning a floor surface by rotating a rotating brush while traveling, and more specifically, it relates to a rotating brush. The present invention relates to a squeegee that absorbs sewage remaining on the floor after being washed and collects it in a sewage tank.

[0002]

2. Description of the Related Art A conventional general squeegee for a floor cleaning machine is shown in FIG. 7 (A), or Japanese Utility Model Laid-Open No. 6-38848, No. 6-79454, No. 6-58853. , Two flexible blades are attached in parallel and linearly with a space between them, and a suction action of a blower is exerted between these two flexible blades.
With this suction force, the flexible blade is configured to suck up the dirty water collected from the floor surface.

On the other hand, the squeegee (parabolic squeegee) in which the whole is bent and formed into a substantially bow shape as shown in FIG. 7B or Japanese Unexamined Patent Publication No. 52-75064, or As shown in FIG. 7 (C), the whole is approximately V
The squeegee formed in a V shape collects the sewage collected by the rotating brush while collecting it in the center, so that the squeegee is more straight than the conventional general squeegee described above. It has the advantage of being able to suck up the oil reliably and efficiently.

[0004]

However, in the squeegee which is formed as a whole in a substantially bow shape or a substantially V shape as described above, the frame or the like for supporting the squeegee must also be made in the bow shape or the V shape. Therefore, there is a problem in that the structure is more complicated than the conventional general squeegee in which the whole is formed linearly, and the manufacturing cost is increased.

Therefore, a technical object of the present invention is to make it possible to produce an excellent water collecting function similar to that of the bow-shaped squeegee or the V-shaped squeegee in a simple method without increasing the cost. .

[0006]

[Means for Solving the Problems] Means taken in the present invention for solving the above technical problems are as follows.

On the floor after cleaning with a rotating brush
A squeegee for a floor washer configured to suck up the remaining dirty water from the floor with a suction force of a blower while scraping it with a flexible blade,

(1) While forming the whole of the flexible blade flat, the shape of the ground surface side of the flexible blade in contact with the floor surface is made into a substantially arc shape with the central part swelling downward. To configure.

[0009] (2) while forming the whole of the flexible blade flat, the shape of the contact <br/> ground surface side of the flexible blade in contact with the floor surface, the central portion is projected to the lowermost substantially Configure in a V shape.

(3) The flexible blade is made of a rubber material having a hardness of 40 to 70.

According to the means described in (1) above, when the flexible blade is grounded on the floor surface and the squeegee is moved, the flexible blade is formed in a substantially arc shape on the ground surface side. Since the tangent part to the floor surface is deformed into an arc shape that curves backward with respect to the traveling direction, as a result, the entire flexible blade can be shaped like an arc squeegee. Thus, it is possible to create an excellent water collecting function similar to that of an arched squeegee by a very simple method of replacing the flexible blade.

According to the means described in (2) above, since the ground contact side of the flexible blade is formed in a substantially V shape,
As in the case of the flexible blade formed in the substantially arc shape, when the squeegee is moved, the tangent portion with the floor surface is deformed into a substantially V-shaped curve rearward with respect to the traveling direction. The entire flexible blade can be made to have a shape corresponding to a V-shaped squeegee, and therefore, by exchanging the flexible blade, the same excellent water collecting function as that of the V-shaped squeegee is exhibited. To be able to do.

When a flexible blade is made of a rubber material having high rigidity, the flexible blade bends linearly to make the tangent line to the floor surface linear. According to the means described in (1), since the flexible blade is made of a rubber material having a relatively low hardness of 40 to 70, the tangent shape to the floor surface is formed into a substantially bow shape or a substantially V shape. Definitely transform,
It is possible to exert an excellent water collecting function.

As described above, the above (1)-
The technical problems described above can be solved by the means described in (3), and the problems of the conventional technology can be solved.
