[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a detergent supply device for dissolving a predetermined amount of detergent or the like and supplying it to a washing tub.

[0002]

2. Description of the Related Art Conventionally, the following is known as this kind of detergent supply device. That is, a box having an opening on the front side and connected to the washing tub side by a supply path, and a container for putting a detergent in the box can be stored, and the detergent in the container is dissolved in water and supplied to the washing tub. A detergent supply device is disclosed in Japanese Utility Model Laid-Open No. 60-64784.

In this conventional example, the supply path and the outside are not sealed. For this reason, odors generated when performing a special cleaning process for business use (for example, removal of excess chemicals such as pigments and dyes) and steam generated by washing with hot water flow backward from the washing tub side through the supply path. Introduced in the box,
After that, the detergent is leaked from the opening through which the detergent container is put in and out.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve the above-mentioned problems, and it is necessary to prevent a bad smell or vapor from flowing backward from the washing tub side and flowing out to the washing processing work room. The purpose is to prevent the working environment from deteriorating.

[0005]

A solution according to the present invention comprises a container for storing a detergent and a container for storing the container.
Having a surface opening, and lowering from the front opening toward the back side.
A box-shaped box having an inclined bottom surface, and the box
Water to the container stored in the container to dissolve the detergent,
Detergent water in which the detergent is dissolved from the container is placed in the box.
A water supply device that overflows with the water supply device,
In order to supply the detergent water overflowing from the container to the washing tub,
Communicate with the washing tub provided at the lowest position on the bottom of the box
A supply port that normally closes the supply opening by its own weight, the
Floats by overflowing the detergent water from the container is obtained with a float valve which opens the supply port.

[0006]

When the detergent in the container is dissolved in water and overflows into the box, the float valve at the supply port rises and opens, and the detergent water flows out from the supply port to the washing tub side. When the water supply to the container is completed and the detergent water in the box is exhausted, the float valve is lowered, the supply port is closed by the float valve, and the box and the washing tub side are shut off by the float valve.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. The present invention is not limited by the following embodiments.

[0008] P is a detergent supply device, which is incorporated in a drum type washing machine and is disposed above a washing tub (not shown). Reference numeral 1 denotes a box-shaped box, the bottom surface of which is high on the near side and the bottom side is a stepped shape with a low depth, and forms a bottom surface 1c inclined toward the rear side. 1b is a supply port provided at the lowest position of the box 1, and 1a is an opening provided on the front surface of the box 1. Numeral 6 is a hinge mounted on the front side and upper side of the box 1. The hinge 6 has an inverted L-shaped cross section, and an outer lid 7 for covering the opening 1a is rotatable upward. Mounted on

2 is a cup-shaped container for storing detergents and the like.
A main body 2a having a high peripheral wall on the front side and a low peripheral wall on the rear side, and a handle 2 attached to the outer surface of the front peripheral wall of the main body 2a.
b, is removably housed in the box 1 through the opening 1a, and is placed on the bottom surface 1c. Reference numeral 3 denotes a water supply device attached to a location near the upper wall of the box 1 near the front side. Numeral 4 denotes a positioning plate hanging from the upper wall of the box 1, which positions the container 2 by bringing the inside of the edge of the container 2 on the handle portion 2b side into contact. Reference numeral 5 denotes a float valve housed in the box 1, which normally closes the supply port 1b by its own weight, but is configured to have the weight and size to float up by the overflow water and open the supply port 1b.

On the upper right side of the drum type washing machine W, a detergent supply device P is incorporated with its outer lid 7 facing forward.
Reference numeral 8 denotes a control panel disposed on the left side of the detergent supply device P, and reference numeral 9 denotes a door for taking in and out laundry. 10 is an outer tub for storing laundry and covering the outer periphery of the rotating washing tub and storing water, 11
Is a drive motor arranged below the outer tub 10, 12 is a belt,
13 is a pulley. Reference numeral 14 denotes a supply path composed of a pipe connected from the supply port 1b to the washing tub.

As described above, in the detergent supply device P, when the container 2 is set at a predetermined position (the middle portion on the bottom surface) of the box 1 and water is supplied from the water supply device 3, the detergent in the container 2 is dissolved and the detergent water in the container 2 is dissolved. Flows out into the box 1 and accumulates on the supply port 1b side. Then, the float valve 5 rises and the supply port 1 rises.
Open b. Detergent water is supplied from the supply port 1b to the outer tub 10 (wash tub) of the drum type washing machine W via the supply path 14. The detergent water overflowing from the container 2
When the outflow ends, the float valve 5 descends by its own weight and closes the supply port 1b.

Therefore, odors such as pigments, dyes and finishing agents from the inside of the washing tub when performing a special cleaning process, and steam and the like when performing hot water washing flow back from the supply path 14 into the box 1 for cleaning. It can be prevented from flowing into the processing work chamber.

The positioning plate 4 prevents splashes overflowing from the container 2 from flying toward the inside of the box 1.

FIG. 4 shows another embodiment, in which three sets are prepared by setting the container 2 and the water supply device 3 as a set. The inside of the box 1 is divided into a plurality of chambers by a partition plate 15, and the containers 2 in each of the chambers include, for example, a detergent (mainly powdery), a cleaning aid (sodium metasilicate, powdery) for improving the cleaning effect, And bleaching. A finishing agent (sodium hypochlorite, liquid) or the like for sterilization is added.

Water is supplied from each water supply device 3 to the container 2 at the time of charging at a timing in accordance with the control of the washing process, and the detergent and the like in the container 2 are dissolved and flow out to the box 1 to be supplied. It accumulates on the mouth 1b side. Then, the float valve 5 rises to open the supply port 1b, and is supplied to the outer tank 10 via the supply path 14. When the outflow from the box 1 is completed, the float valve 5 descends by its own weight and closes the supply port 1b, and closes the supply port 1b until the next stroke. As described above, when the detergent or the like is supplied at each timing, the supply port 1b is automatically opened and closed by the float valve 5 depending on the presence or absence of the detergent water or the like in the box 1, and the detergent or the like is not supplied. In this case, odor, steam, and the like are prevented from flowing backward from the supply path 14 to the inside of the box 1 from the outer tank 10 side, and are prevented from flowing out of the opening 1a into the cleaning processing work chamber.

[0016]

According to the detergent supply device of the present invention, the supply path connecting the box connected to the outside of the washing tub and the outside can be shut off, so that the odor and steam flowing backward from the washing tub to the washing processing work room. Can be sealed off, and the environment of the washing work room does not deteriorate.
