As shown in the drawings, a squeegee is provided behind the cleaning brush to suck up dirty detergent liquid or water after cleaning (hereinafter simply referred to as sewage) by a suction action of a suction blower. Both of them clean the floor and absorb and wipe off sewage.

[0003] Further, in the floor cleaning machine having the above configuration,
When the suction blower of the washing machine is performing the suction operation, the squeegee is sucking up the sewage on the floor, but when the operation of the suction blower is stopped by turning off a switch or the like on the washing machine side,
There has been a problem that a drop phenomenon occurs in which water droplets attached to the hose drop from the squeegee to the floor from the squeegee, and the floor that has been cleaned neatly is again contaminated with the dropped wastewater.

Therefore, conventionally, for example, Japanese Utility Model Application No. 63-99
No. 07 (Japanese Utility Model Laid-Open No. 1-115454), a trap is provided in the middle of a hose connecting a squeegee and a blower, or a suction blower and a squeegee S are used as shown in FIG.
A bent portion Hb wound round with a cord B is formed at the lower end portion of the hose H connecting between the traps and the trapped water or the above-mentioned sewage dripped when the operation of the suction blower is stopped in the bent portion Hb. This prevented recontamination of the floor surface. In FIG. 4, Ha is a connection cuff attached to the lower end of the hose H, Sa is a connection port of a squeegee S for fitting the cuff Ha, M is a cleaning brush, and Ma is a leaf spring for attaching the squeegee S. It is.

[0005]

However, if a trap or a bent portion Hb is provided on the hose as described above, dust sucked up together with the sewage accumulates in this portion, and once the trap or the bent portion Hb is formed. There is a problem that the garbage collected on the inner wall adheres to the inner wall surface and cannot be easily taken out.

Accordingly, a technical problem of the present invention is to prevent sewage from dripping from a squeegee when the suction blower is stopped, and to remove sewage from a squeegee in a floor washer which can easily remove accumulated dust. It is to provide a drip prevention device.

[0007]

Means taken by the present invention to solve the above technical problems are as follows.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the apparatus for preventing sewage dripping in a floor washer according to the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a perspective view of a floor washing machine in which a device for preventing sewage dripping according to the present invention is implemented. In the drawing, reference numeral 1 denotes wheels 1b and 1c and an operating handle 2;
The washing machine 1 is provided with a front cover 1a so as to be openable and closable. Inside the washing machine 1 is a collection tank 5 for storing the sewage after washing, and a suction which exerts a suction action on the collection tank 5 through a hose 6M. A blower M and a water supply tank T containing a detergent liquid or water for cleaning are stored.

Reference numeral 3 denotes a brush case body on which a cleaning brush 3a rotated by a motor (not shown) is mounted on the bottom surface side. The entire brush case body 3 is operated by operating a pedal or lever as shown in the figure. An arm (not shown) is provided on the front of the washing machine 1 so that the washing brush 3a can be contacted on the floor by being raised upward or downward.
The cleaning brush 3a in the brush case body 3 is connected to the water supply tank T during cleaning.
Is supplied with a detergent solution or water through a hose (not shown). Reference numeral 4 denotes a squeegee provided between the washing machine 1 and the brush case body 3. The squeegee 4 is operably connected to the rear of the brush case body 3 by a leaf spring 3b.

FIGS. 2 and 3 are an exploded perspective view showing a main part of the present invention and an enlarged side sectional view showing the main part.
In the figure, reference numeral 4a denotes a connection port protruding from the upper surface of the central portion of the squeegee 4, 4b denotes a bolt for mounting a leaf spring similarly provided on the upper surface of the squeegee 4, and 4c denotes a tightening nut for mounting the leaf spring.
Further, 4d and 4e are rubber plates attached to the bottom surface of the squeegee 4, and 4f are rubber plates 4e and 4 attached inside the squeegee 4.

The apparatus for preventing sewage dripping according to the present invention is used by being applied to the washing machine 1 having the above-described configuration, and the detailed configuration thereof is shown in FIGS. 2 and 3. That is, in each of the drawings, reference numeral 6 denotes a hose for sucking sewage having an upper end connected to the sewage tank 5 described above. The suction operation of the suction blower M is performed through the hose 6M and the collection tank 5. It is a mechanism that extends to the side.

In the figure, reference numeral 7 denotes a lower end 6a of the hose 6.
And a cuff connecting between the connection port 4a of the squeegee 4 and upper and lower connection ports 7b and 7c, respectively.
In addition, the entire cuff 7 is bent substantially in the shape of a letter as shown in FIG. Reference numeral 7a denotes a water reservoir formed on the inner wall portion of the inner bent portion of the cuff 7 so as to bulge downward and outward. The portion of the cuff 7 having the water reservoir 7a is formed by the other hose 6. The cross section is formed in a substantially oval elliptical shape so that the flow velocity does not decrease due to an extremely large cross section. Reference numeral 7a1 denotes an internal water reservoir chamber of the water reservoir 7a.

Further, the cuff 7 is entirely or at least provided with a water reservoir 7a so as to push the water reservoir 7a from the outside with a finger or the like to discharge the dust accumulated inside.
Is formed using a rubber material that can be freely pressed and restored by itself, a soft plastic material, or the like.

Since the apparatus for preventing sewage dripping in the floor washer according to the present invention has the above-described configuration, when the operation of the suction blower M is stopped to stop the suction action on the squeegee 4, the collection tank 5 is stopped. The sewage flowing along the inner wall of the hose 6 and flowing down in the direction of the squeegee 4 without being completely collected enters the sump chamber 7a1 of the sump 7a at the cuff 7 and is stored there. This solves the problem of soiling the floor surface by dripping on the surface.

The entire cuff 7 is bent substantially in the shape of a letter, and since the water reservoir 7a is formed at the inside bent portion of the cuff 7, the cuff 7 extends along the inner wall of the cuff 7. Most of the sewage flowing down is dropped into the sump chamber 7a1 of the sump section 7a, and can be prevented from flowing down to the squeegee 4.

Further, since the water reservoir 7a is configured to be able to be pushed from outside by a finger or the like, the water reservoir 7a
When dust accumulates in a1, it is possible to push the dust and discharge the dust. When discharging the dust, if the water reservoir 7a is pushed while the suction blower M is being suctioned, the discharged dust can be kept as it is without soiling the inside of the squeegee 4 or the floor surface. The collection processing can be performed on the collection tank 5 side.

[0019]

According to the present invention, the apparatus for preventing sewage dripping in the floor washer according to the present invention can solve the problem of sewage dripping from the squeegee to the floor when the suction blower is stopped.
