Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a floor cleaning machine that cleans a floor surface with a rotating brush while running.

[Conventional technology]

Conventional floor cleaning machines have a configuration in which a cleaning brush rotated by a motor is attached to the bottom of the machine body, and a squeegee for suctioning dirty water is installed at the rear of this brush. The floor surface is cleaned by supplying cleaning liquid to the area, and the squeegee absorbs the dirty water generated by the cleaning using the suction power of the blower motor.

When cleaning the floor using the floor cleaning machine configured as described above, the cleaning brush is installed at the center of the bottom of the cleaning machine, with wheels for movement placed at the front and rear of the cleaning brush. When cleaning a floor near a wall, the front part of the cleaning machine hits the wall first, making it impossible to clean the floor, and it is also impossible to suction the sewage with a squeegee.

Therefore, as seen in, for example, Japanese Utility Model Publication No. 39-2718 and Japanese Utility Model Publication No. 40-8506, cleaning brushes are placed near the front of the aircraft body, rather than at the center of the bottom of the aircraft body, so that it is close to the wall surface. A cleaning machine has been developed that can clean floors without any problems.

[The problem that the idea aims to solve]

However, the floor cleaning machine configured as above,
Since the squeegee is still installed at the rear of the machine, even if the cleaning brush installed near the front of the machine can clean the floor near the wall, the squeegee cannot suck up the dirty water that has accumulated during this cleaning. There is a problem that cleaning waste water remains near the wall surface.Additionally, since the cleaning brush and squeegee are installed at a distance from each other at the front and rear of the aircraft, it is difficult to clean the cleaning brush. There were cases where the squeegee at the rear could not reliably suck up the generated sewage, resulting in the problem of sewage stains remaining on the floor.

In addition, since there are many uneven surfaces on the floor, it is necessary to move the cleaning brush up and down to follow these unevenness when cleaning. It is necessary to keep the cleaning brush away from the floor to protect the surface, but the conventional floor cleaning machines mentioned above have a structure in which the cleaning brush moves up and down independently, and a separate mechanism is required to move the squeegee up and down. Since it is necessary to provide the above-mentioned device, the entire device becomes complicated, resulting in an increase in size and cost.

In addition, when replacing the brush and squeegee or performing repairs, the entire cleaning machine must be tilted on its back or lifted.
There were also problems that the work was dangerous and difficult to do.

Therefore, the technical problem of the present invention is to make it possible to clean the floor near the wall, and also to suction the sewage, so that the cleaning sewage is sucked out without leaving it on the floor, and at the same time, with an extremely simple mechanism. A floor in which the cleaning brush and squeegee can be moved up and down together to follow the unevenness of the floor surface, can be held tilted away from the floor surface, and can be maintained safely and easily by replacing the brush or squeegee. Our objective is to provide surface cleaning machines.

[Means to solve the problem]

The measures taken in the present invention to solve the above technical problems are as follows.

(1) A cleaning brush body rotated by a motor is attached to the front part of a cleaning machine configured to be freely movable so as to be movable up and down via a link.

(2) A squeegee for suctioning waste water shall be installed between the cleaning brush body and the cleaning machine body.

(3) Connecting the squeegee to the rear of the cleaning brush body using a leaf spring so that the squeegee can move up and down integrally with the cleaning brush body and can move in the left and right directions with respect to the cleaning brush body. .

(4) A one-touch stay should be installed between the cleaning brush body and the cleaning machine body to hold the cleaning brush body and squeegee in place when lifted from the floor.

However, here, the squeegee refers to a suction port that applies the suction force of the blower motor to the floor surface to suck up waste water accumulated on the floor surface, and the one-touch stay refers to a suction port that can be slid freely into the cylinder. A retainer that is configured so that when the arm is pulled out to a certain length, the stopper engages and holds the arm in its extended state.

[Effect]

The above means works as follows.

The factor (1) above is that since the cleaning brush body is installed on the front part of the cleaning machine body, it is possible to clean even floors close to walls without being obstructed by the cleaning machine body. It moves up and down to follow the unevenness of the floor, making it possible to thoroughly clean even the uneven parts of the floor.

The element (2) above is that the squeegee for suctioning sewage is installed at the front of the cleaning machine in the same way as the cleaning brush body.
Moreover, since it is installed directly behind the cleaning brush body, it is possible to cleanly suck up the sewage remaining on the floor near the wall, and it also allows the sewage to be left on the floor after cleaning with the cleaning brush body. This allows for immediate suction without causing any damage or scattering to the surrounding area.

The element (3) above is such that the squeegee, which is connected to the immediate rear part of the cleaning brush body via a leaf spring, moves up and down together with the cleaning brush body, and also in the horizontal direction with respect to the cleaning brush body. Since it rotates freely, it is possible to follow the movement of the cleaning brush body to reliably suction cleaning waste water, and it also makes it possible to lift and rotate the cleaning brush body and squeegee together.

The factor (4) above is that the one-touch stay holds the cleaning brush and squeegee in place when they are lifted upwards, so when the washer is stored or moved, the cleaning brush and squeegee are held in an inclined position. In addition to protecting the floor by holding it in place, you can also replace or repair the cleaning brush and squeegee.
This enables safe and convenient operation in this inclined state.

As described above, the above-mentioned technical problem can be solved by the above-mentioned means, and the problems of the conventional technology can be solved.
