DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dishwasher used by supplying water from a pipe through a water supply hose connected to a dishwasher body.

[0002]

2. Description of the Related Art Conventionally, this type of dishwasher has been configured as shown in FIG. Hereinafter, the configuration will be described.

As shown in FIG. 1, a dishwasher main body 1 includes a water supply hose 2 for supplying tap water or the like into the dishwasher main body 1.
And a drain hose 3 for draining washing water or the like that has washed the dishes in the dishwasher body 1 is connected to the back. The dishwasher main body 1 is installed on a table 4, and a water supply pipe 5 connected to the water supply hose 2 and the drainage hose 3 and a water supply pipe 5 from the indoor, and a drain pipe 6 are provided at a substantially central portion below the table 4. Provided.

As shown in FIG. 7, a water supply pipe 5 and a drain pipe 6 are provided so as to rise from the floor, respectively.
Is provided with a water supply hose connection screw portion 7 connected from the rising portion to the water supply hose 2 and a water stop cock 8 for stopping water supply. The water supply hose 2 and the water supply pipe 5 are connected to each other by tap water pressure. It is connected with a screw system to add to the part.

As another indoor piping method, there is a method in which an indoor piping member is placed on the floor surface and connected to a water supply / drainage hose similar to the above at a substantially central portion below the table 4.

[0006] In the above configuration, the order of the water supply / drainage work will be described. The installer installs the table 4 in the space where the dishwasher main body 1 is installed. At this time, the indoor water supply pipe 5 and the drain pipe 6 have already been set up substantially in the center below the table 4 as shown in FIG.

[0007]

In such a conventional structure, a water supply hose 2 and a drain hose 3
An indoor water supply pipe 5 and a drain pipe 6 connected to the
Is provided in the approximate center of the lower part of the table, so that the work of connecting water supply and drainage from the front of the table 4 is performed by sunk into the table 4, resulting in poor workability and work in a narrow space. However, there has been a problem that the connection of the connecting portion is unreliable and water leakage occurs. In particular, the connection part on the water supply side receives tap water pressure and connects with a screw system, so a tool such as a wrench is required, making connection work in a narrow space difficult, and factors that cause water leakage Had become.

Further, even if some abnormality occurs in the dishwasher main body 1 and the user disconnects the water supply hose 2, since the water stop cock 8 is located substantially at the center of the lower part of the placing table 4, the work is performed by squatting. However, there is a problem that the work of removing the screw cannot be easily performed.

The present invention solves the above-mentioned problems, improves the workability of connecting a water supply hose, reliably connects and connects a connection portion in a narrow space, and causes a problem in the dishwasher body when any abnormality occurs. Even if the person disconnects the water supply hose,
It is intended to be easy to work.

[0010]

According to the present invention, in order to achieve the above object, when a water supply hose connected to a dishwasher body is connected to a pipe, a convex plug is connected to one of the water supply hose and the pipe. And a concave coupler is provided on the other side, and the plug and the coupler are connected to each other, so that the water supply hose and the pipe can be detachably connected in a concealed space that can be released from the outside.

As a result, the workability of connecting the water supply hose can be improved, the work using a tool in a narrow space can be eliminated, and the connection portion can be reliably connected and constructed. Even when a certain abnormality occurs in the main body of the washing machine and the user disconnects the water supply hose, the operation can be easily performed without using a tool.

[0012]

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

(Embodiment 1) As shown in FIG. 1, a dishwasher main body 9 is constructed so as to be installed in a system kitchen 10 in a built-in manner. A water supply hose 11 for supplying tap water or the like to the inside 9 and a drainage hose 12 for draining washing water or the like for washing dishes in the dishwasher body 9 are connected. The dishwasher body 9 is installed on a table (cabinet) 13.

An indoor water supply pipe (pipe) 14 protrudes from the wall and protrudes to the vicinity near the front inside the pedestal 13, and the water supply hose 11 enables connection work with the water supply pipe 14 near the front of the pedestal 13. ing. Similarly to the water supply pipe 14, the indoor drain pipe 15 is protruded from the wall to the front of the pedestal 13 so that the drainage hose 12 and the drain pipe 15 can be connected near the front inside the pedestal 13. I have.

A water stop cock 16 is provided in front of the water supply pipe 14 so that water supply to the dishwasher body 9 can be opened and closed. A convex plug 17 is provided at the tip of the water supply hose 11, and a concave coupler 18 is provided at the water supply pipe 14. The plug 17 and the coupler 18 can be connected by simply inserting them. Further, the plug 17 and the coupler 18 are each provided with a claw 19 as a locking mechanism for retaining.
Is provided. Attach the door 20 to the front of the table 13,
By opening the door 20, the inside of the table 13 is made a concealed space that can be released from the outside.

FIG. 2 shows the details of the configuration of the plug 17 and the coupler 18. The plug 17 is convex and has a strainer 21 inside.
Is provided. The plug 17 itself is screwed to the water supply hose 11 of the dishwasher body 9. The plug 17 side is configured with a male thread, and the water supply hose 11 side is configured with a female thread. The coupler 18 has a sleeve 22 at the tip of the coupler 18. The sleeve 22 is urged in the distal direction by an urging spring 23.

When the sleeve 22 is pushed in the root direction, the ball 24 is movable in the radial direction and the packing 2 for sealing is used.
Five. The coupler 18 is screwed to the water supply pipe 14. The coupler 18 side is configured with a female screw, and the water supply pipe side 14 is configured with a male screw. The female screw of the water supply hose 11 and the male screw of the water supply pipe 14 can be screwed together with the same screw diameter.

When the tip of the plug 17 is inserted into the coupler 18 while pushing down the sleeve 22 of the coupler 18, the ball 24 moves outward, the plug 17 is mounted in the coupler 18, and the connection portion can be sealed by the packing 25.
When the sleeve 22 is returned to its original position, the ball 24 returns in the inner diameter direction, and the plug 17 does not come off from the coupler 18. However, in this embodiment, a claw portion 19 is further provided as a lock mechanism for retaining the plug. Claw 19 is plug 17
Can be securely caught by the flange portion 26 and can be prevented from coming off.
