Abstract

PURPOSE:To decrease the returning of waste water which remains in a squeegee hose to the cleaning surface and to obtain the squeegee hose which can collect its small quantity of waste water by forming annularly a middle part of the squeegee for connecting a squeegee for water absorption and a waste water tank. CONSTITUTION:Waste water on the floor is sucked by the squeegee by using vacuum pressure generated by a water absorption motor and sucked into the waste water tank 2 through a squeegee hose 5. In this case, since an annular part 6 is formed in the middle part of the squeegee hose 5, what is called a trap effect is obtained and even if a water absorption motor 3 is stopped, the greater part of waste water which is being sucked is received in the annular part 6, only a very small quantity of waste water being lower than the annular part 6 returns to the floor surface. Subsequently, the squeegee 4 is detached from the squeegee hose 5 and waste water which returns directly to the floor surface from the squeegee hose 5 is sucked. In such a manner, the waste water quantity of suction residue can be decreased and the waste water which returns to the cleaning surface is cleaned locally.

Description

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 waste water tank in a floor cleaning machine.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 5, a squeegee hose 8 of this type of floor cleaning machine has a squeegee 9 for absorbing water which is located at a lower portion of a rear portion of a main body and a sewage tank which is located at an upper portion of the main body. Was connected by a squeegee hose 8 arranged substantially vertically.

That is, the communication from the squeegee 9 to the dirty water tank is connected to the squeegee hose 8 so that the ventilation resistance by the squeegee hose 8 is as small as possible, and the length of the squeegee hose 8 is also short from the intention.

[0004]

However, in the above squeegee hose 8, when sewage suction is stopped midway,
Since sewage remains in the squeegee hose 8, this sewage returns to the squeegee 9 side, and the cleaning surface is contaminated with sewage. Therefore, it has been a subject to reduce the returned sewage as much as possible and to be able to clean the sewage returned to the cleaning surface.

Further, since the length of the squeegee hose 8 is short, the squeegee 9 is pulled to impair the ability of the squeegee 9 to follow the cleaning surface during cleaning and use, for example, when the machine body rotates.
There was also the problem of solving the poor usability, such as leaving the dirty water absorbed.

An object of the present invention is to solve these problems and to provide a squeegee hose for a floor cleaning machine which is excellent in usability.

[0007]

The first means of the present invention for achieving the above object is to provide a squeegee tank and a water absorption motor in the main body, and connect a squeegee for water absorption and the sewage tank with a squeegee hose. In the washing machine, the middle part of the hose is formed in an annular shape.

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

A third means is to construct a squeegee hose for a floor cleaning machine by forming an intermediate portion in an annular shape and locking an annular crossing portion with a hose clip.

[0010]

In the first means of the present invention described above, since the squeegee hose is formed in an approximately middle portion in an annular shape, even if sewage remains in the squeegee hose, the squeegee hose is trapped in the intermediate annular portion and only the sewage at the lower portion of the squeegee hose is trapped. Without returning to the cleaning surface, the amount of unsucked residue is extremely small. Further, by appropriately setting the annular length, the squeegee hose can be removed from the squeegee and used for collecting wastewater, and the wastewater returned to the cleaning surface can be locally cleaned. Moreover, the length of the squeegee hose can be made sufficiently long without impairing the followability of the squeegee.

In the second means, the annular portion acts as a spring body by locking the annular crossing portion with the hose clip, and the squeegee is prevented from being unnecessarily pulled, and the squeegee on the cleaning surface is prevented. 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 is a main body of a floor cleaning machine, 2 is a waste water tank provided in an upper portion inside the main body 1, and 3 is a water absorption motor also provided in the main body 1. The squeegee 4 for absorbing water and the dirty water tank 2 are connected by a squeegee hose 5. The squeegee hose 5 has an annular portion 6 formed in the middle thereof. Reference numeral 7 in the drawing is a hose clip.

Next, the operation of the above configuration will be described. Due to the vacuum pressure generated by the water absorption motor 3, the squeegee hose 5 cleans the dirty water on the floor that is the cleaning surface from the squeegee 4.
Suck into the dirty water tank 2 via.

In this process, since the annular portion 6 is formed in the middle portion of the squeegee hose 5, a so-called trap effect is obtained, and even if the water absorption motor 3 is suddenly stopped, most of the waste water being sucked is the annular portion 6. It is received inside and only a small amount of dirty water from the annular part 6 returns to the floor as the cleaning surface and falls. Moreover, since the squeegee hose 5 has a marginal length in the annular portion 6, if the squeegee hose 5 is detached from the squeegee 4 and extended as shown in FIG. Since the degree of vacuum is concentrated, a small amount of sewage returned to the floor can be easily collected. Moreover, the length of the squeegee hose 5 can be made sufficiently long, and the squeegee 4 can be rotated when the main body 1 is rotated.
It does not impair the ability to follow the floor surface.

FIG. 4 shows an embodiment of the second means, in which the hose clip 7 locks the intersecting portion of the annular portion 6 so that the portion of the annular portion 6 functions as a spring body and the squeegee 4 is unnecessarily pulled. It prevents the squeegee 4 from floating on the cleaning surface and does not impair the followability of the squeegee 4 to the cleaning surface.

[0017]

As is apparent from the above description of the embodiments, in the first means of the present invention, the annular portion is formed substantially in the middle of the squeegee hose. Are trapped and only the dirty water in the lower part of the annulus returns to the cleaning surface, and the amount of unsucked residue is extremely small. Further, by appropriately setting the length of the annular portion, the squeegee hose is removed from the squeegee, and the dirty water returned to the floor is directly sucked from the squeegee hose without passing through the squeegee, so that cleaning can be locally effective. Moreover, the length of the squeegee hose can be made sufficiently long, and the followability of the squeegee is not impaired.

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

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