Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a so-called built-in type dishwasher.

[0002]

2. Description of the Related Art Conventionally, as a dishwasher of this type,
There is one disclosed in Japanese Utility Model Publication No. 1-91461. As shown in FIG. 20 and FIG. 21, this is to connect the water supply pipe 4 and the drainage pipe 5 inside the machine to the existing water supply pipe 2 and drainage pipe 3, respectively, which are incorporated in the system kitchen 1. An existing pipe introduction port 7 is formed at the back of the machine (back of the main body 6), and a pipe duct 8 is provided inside the machine (inside the main body 6) from the introduction port 7 to incorporate the main body 6 into the system kitchen 1 described above. As a result, the existing pipes 2 and 3 are introduced into the pipe duct 8 through the introduction port 7, and the in-machine pipes 4 and 5 are connected to them from the front of the machine.

[0003]

In the case of the above, the inlet 7 is used for passing the swelling water stopcock 9 of the existing water supply pipe 2 at the tip thereof, and the pipe position of the existing pipes 2, 3. It is made large enough considering the error of
After introducing the existing pipes 2 and 3, a large gap C is generated between these and the peripheral portion of the introduction port 7. However, since there is a risk that a mouse will enter through this gap C and bite and damage the in-machine pipes 4, 5 and other in-machine parts, a shielding plate 10 is attached to the in-machine end of the pipe duct 8. There is.

However, as described above, the piping duct 8
However, in the case where the shielding plate 10 is attached to the end portion inside the machine one by one, there is a problem that the installation work cost is high due to the installation work cost and the component cost of the shield plate 10. Moreover, when the existing pipes 2 and 3 are largely displaced in the pipe duct 8 when mounting,
There is also a problem that the shield plate 10 cannot be attached.

Further, even if the attached shield plate 10 can prevent the mouse from entering, it is inside the aircraft ahead of the pipe duct 8 and cannot prevent the mouse from entering the pipe duct 8. There was a possibility that the existing pipes 2 and 3 in the pipe duct 8 might be bitten by the rat and damaged.

The present invention has been made in view of the above circumstances, and therefore an object thereof is to provide a dishwasher capable of preventing the entry of mice into the machine and the piping duct without the need for a shield plate. is there.

In order to achieve the above object, in the dishwasher of the present invention, there is a dishwasher which is incorporated in a system kitchen or the like to connect an in-machine pipe to an existing pipe. It is characterized in that it is provided with a piping duct which is surrounded and has one end attached to a floor or a wall and which is introduced into the machine from the other end.

[0008] In this case, it is preferable that the inside of the machine is provided with a locking portion for locking the other end of the introduced pipe duct. Further, it is preferable that the pipe duct has a bellows shape that can be expanded and contracted and bent. .

Further, the pipe duct may be formed in a shape in which one end is wide and the width is gradually narrowed from the one end to the other end. Then, it is preferable to provide a mounting plate which is provided so as to project from the floor or wall and to which one end of the pipe duct is attached instead of them.

[0010]

According to the above-mentioned means, it is sufficient to form an inlet which is slightly larger than the piping duct surrounding the existing piping in the machine body, and the outside end of the piping duct is on the floor or wall. Since the mouse is attached to and blocked, the mouse can be intruded from the inlet and the mouse can be intruded into the pipe duct without using a shielding plate.

In this case, particularly in the case where the machine is provided with a locking portion for locking the other end of the introduced piping duct, the other end of the piping duct can be easily fixed. Also, with the bellows-shaped pipe duct that can be expanded and contracted and bent, even if the position of the attached piping duct is slightly displaced from the position of the incorporated machine body, the bellows of the piping duct can expand and contract and bend and expand easily. Can respond.

Moreover, in this case, the bellows of the pipe duct is
In the case where the slope of the inboard side of each crest is longer than that of the slope of the outboard side, when the bellows are contracted, each crest tilts to the outside of the machine and the existing pipe is installed. It does not interfere with.

On the other hand, in the case where the pipe duct is formed in a shape in which one end is wide and the width is gradually narrowed from the one end to the other end, when the protruding position of the existing pipe is deviated in the lateral direction, Even if the existing pipes are deformed in the middle, they can be easily received and surrounded.

When the existing pipe is a floor rolling pipe, the one end of the pipe duct is attached in the case where the existing pipe is a floor rolling pipe. Can be done without problems.
