DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a squeegee hose for connecting a squeegee and a sewage tank in a floor washer.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 5, a squeegee hose 8 of this type of floor washer has a squeegee 9 located at a lower portion at a rear portion of a body and a sewage tank located at an upper portion in the body. Were connected by a squeegee hose 8 arranged almost linearly up and down.

That is, the communication from the squeegee 9 to the sewage tank is connected to the squeegee hose 8 so that the ventilation resistance is as small as possible.

[0004]

However, in the squeegee hose 8 described above, when suction of sewage is stopped halfway,
Since sewage remains in the squeegee hose 8, the sewage returns to the squeegee 9 side, and there is a disadvantage that the cleaning surface is soiled with sewage. Therefore, it has been a problem to reduce the amount of returned sewage as much as possible and to be able to clean the sewage returned to the cleaning surface.

In addition, since the length of the squeegee hose 8 is short, the squeegee 9 is pulled, thereby impairing the followability of the squeegee 9 to the cleaning surface during cleaning use, for example, when the body rotates.
There was also a problem of solving poor usability such as sucking and leaving sewage.

[0006] It is an object of the present invention to solve these problems and to provide a squeegee hose for a floor washer excellent in usability.

[0007]

According to a first aspect of the present invention, there is provided a floor in which a sewage tank and a water absorption motor are provided on a main body, and a squeegee for water absorption and a sewage tank are connected by a squeegee hose. In the cleaning machine, an intermediate portion of the hose is formed in an annular shape.

The second means has a squeegee hose having a length such that the squeegee hose is detached from the squeegee and the suction port of the hose can be directly applied to the floor surface without passing through the squeegee.

A third means is to form a squeegee hose of a floor washer by forming an intermediate portion in an annular shape and locking an annular intersection with a hose clip.

[0010]

In the first means of the present invention, since the substantially middle portion of the squeegee hose is formed in a ring shape, even if sewage remains in the squeegee hose, the sewage is trapped in the middle portion of the squeegee hose, and only the sewage in the lower portion of the ring is trapped. It does not return to the cleaning surface, and the amount of unsucked residue is extremely small. By appropriately setting the length of the ring, the squeegee hose is detached from the squeegee and used for collecting sewage, and the sewage returned to the cleaning surface can be locally cleaned. Moreover, the length of the squeegee hose can be made sufficiently long, and the squeegee followability is not impaired.

In the second means, the annular cross portion is locked by a hose clip, so that the annular portion functions as a spring body, preventing the squeegee from being unnecessarily pulled, and moving the squeegee to the cleaning surface. There is no loss of followability.

[0012]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

1 to 4, reference numeral 1 denotes a main body of the floor washer, 2 denotes a sewage tank provided at an upper portion inside the main body 1, and 3 denotes a water absorption motor also provided in the main body 1. The squeegee 4 for absorbing water and the sewage tank 2 are connected with a squeegee hose 5. The squeegee hose 5 has an annular portion 6 formed at an intermediate portion thereof. 7 in the figure is a hose clip.

Next, the operation of the above configuration will be described. The vacuum pressure generated by the water absorption motor 3 causes the squeegee hose 5 to remove sewage on the floor, which is a cleaning surface, from the squeegee 4.
And then into the sewage tank 2.

In this process, since the annular portion 6 is formed in the middle portion of the squeegee hose 5, a so-called trapping effect is obtained. And only a small amount of sewage water below the annulus 6 returns to the cleaning floor. Moreover, since the squeegee hose 5 has a marginal portion at the annular portion 6, the squeegee hose 5 is detached from the squeegee 4 and extended as shown in FIG. Because the degree of vacuum is concentrated, even a small amount of wastewater that has returned to the floor can be easily collected. Moreover, the length of the squeegee hose 5 can be made sufficiently long.
Does not impair the ability to follow the floor.

FIG. 4 shows an embodiment of the second means, in which the intersection of the annular portion 6 is locked by the hose clip 7 so that the portion of the annular portion 6 functions as a spring body, and the squeegee 4 is unnecessarily pulled. This prevents the squeegee 4 from floating from the cleaning surface and does not impair the ability of the squeegee 4 to follow the cleaning surface.

[0017]

As is apparent from the above description of the embodiment, in the first means of the present invention, since the annular portion is formed almost in the middle of the squeegee hose, even if squeeze water remains in the squeegee hose, the annular portion will not be used. Is trapped, only the wastewater at the bottom of the annulus returns to the cleaning surface, and the amount of unsucked water is extremely small. In addition, by appropriately setting the length of the annular portion, the squeegee hose is detached from the squeegee, and the sewage returned to the floor surface is sucked directly from the squeegee hose without passing through the squeegee, so that the cleaning can be locally and effectively performed. In addition, the length of the squeegee hose can be made sufficiently long, and the squeegee followability is not impaired.

In the second means, the intersection of the annular portions is locked by the hose clip, so that the annular portion functions as a spring body, preventing the squeegee from being pulled unnecessarily, and following the squeegee to the cleaning surface. There is no loss of sex.

Thus, the present invention provides an excellent floor cleaning machine squeegee hose.
