It is connected to a water supply (not shown) and a drain (not shown).

The water supply pipe 46 for floor rising and the drain pipe 47 for floor rising shown in FIG. 6 are connected to the water supply hose 39 and the drainage hose 40 held by the hose holding arm 41 while maintaining proper lengths. To be done. Since the system kitchen built-in device main body has a structure in which the hoses on the device main body side are already connected internally, only the floor rising water supply pipe 46 and the floor rising drain pipe 47 are connected.

FIG. 4 shows a state in which the device body 42 is stored in the system kitchen. Water supply hose 39, drain hose 4
0 is the back wall 50, floor 51, and ceiling 5 of the system kitchen
2. The hose is housed in the fixed space (gap) formed by the rear surface of the device body 42 without being crushed.

FIG. 5 shows a state in which the device body 42 is slightly pulled out to the front. By pulling out the device main body 42, the water supply hose 39 and the drain hose 40 receive tension, and the hose holding arm 41 having the least resistance against a horizontal force rotates about the shaft 44 of the arm base 43. . Next, tension is applied to the water supply hose 39 and the drain hose 40 at a position rotated to an appropriate angle, and each hose is pulled out forward.

FIG. 2 shows a state in which the device body 42 is pulled out to the front of the system kitchen. When the device body 42 is installed in the system kitchen for the first time, the water supply hose 39 and the drainage hose 40 previously attached to the device body 42 are connected to the floor rising water supply pipe 46 and the floor rising drainage pipe 47, respectively. It can be used by opening the water shutoff valve. Further, when performing maintenance or repair, the device body 42 is pulled out and the direction is changed as shown in FIG. After each work is completed, the device body 42 is inserted into the system kitchen as shown in FIG.

In this manner, the lower end of the hose holding arm 41 is rotatably supported on the lower portion of the rear side of the device body 42, and the water supply hose 39 and the drain hose 4 are attached to the hose holding arm 41.
Since 0 is held, when the device main body 42 is housed inside the system kitchen, the hose holding arm 41 moves the device main body 4
It is placed along the back of 2. As a result, the hose is folded with the bent portion facing upward. A long hose fits compactly in a narrow space. Since the hose is held along the longitudinal direction of the hose holding arm 41, the hose is folded without buckling,
The hose is stored without being crushed.

Further, when the device body 42 is pulled out from the system kitchen, the hose holding arm 41 falls down lightly so that the end of the hose holding arm 41 is separated from the device body 42, so that the device body 42 can be easily moved to the system kitchen. You can put it outside. The hose is long enough that it can be pulled out of the system kitchen,
It is possible to easily attach and detach the floor rising water supply pipe 46 and the floor rising drainage pipe 47.

FIG. 7 shows another embodiment of the hose holding arm. The hose holding arm 53 is set to be sufficiently longer than the hose holding arm 41 of the previous embodiment, and the arm base 4
3 is attached so as to be rotatable around a shaft 44. Still another hose holding arm 54 (auxiliary hose arm)
The hose holding arm 53 and the auxiliary hose holding arm 54 are rotatably connected to each other by a shaft 55 that interlocks with each other.

The length of the auxiliary hose holding arm 54 is not more than half the length of the hose holding arm 53. In this embodiment, since the hose holding arm 53 is sufficiently long, the water supply hose 39 and the drain hose 40 are held up to the bending point at the highest point. Therefore, when the water supply hose 39 and the drain hose 40 are folded, the hose is not seated. Bending is less likely to occur, and the hose folding and stretching operations are performed more smoothly. A stable movement of the water supply hose 39 and the drainage hose 40 can be configured. Since the auxiliary hose holding arm 54 is short, a place where the hose is not held is sufficiently secured, and when the device main body 42 is taken out of the system kit, the hose flexibility can easily change the direction of the device main body. In this way, the water supply hose 3
9. The drain hose 40, the water supply pipe 46 for floor rising, and the drain 47 for floor rising are connected by pulling out the device main body 42.
It is extremely workable and easy to perform, and does not need to have a tunnel section for hose crawling at the bottom of a conventional dishwasher, so that it is possible to provide a system kitchen built-in device main body with an extremely high space utilization rate.

FIG. 8 shows another embodiment of the water supply pipe for wall discharge and the drain pipe for wall discharge. Water supply pipe for wall 4 protruding from the wall
8. A drain pipe 49 for wall discharge is provided. The hose can be easily attached and detached without changing from the previous embodiment. In the above-mentioned embodiment, two hoses are put together in the hose holding arm, but each hose may be provided with a hose holding arm. Further, the hose arm is a member having a rectangular cross section, but it can be formed in other shapes.

The hose holding arm may be provided on the inner wall side of the system kitchen. The above is the description of the rotation structure of the water supply hose / drainage hose when the device body is stored / pulled out. Next, another element of the present invention will be described.

In the conventional configuration, when the water supply hose 100 is connected to the water supply pipe 101, the water supply pipe 101 is fixed. Therefore, when the nut 103 is screwed, the rotation friction between the packing 102 and the receiving seat 104 inside the water supply hose 100. A force is generated, and the water supply hose 100 on the main device side, which is the free end, is twisted and tightened and fixed.

When the water supply hose on the main body device side is twisted and tightened and fixed, the hose is looped in a state where the device main body is housed in the space as in the present invention and the back (wall) of the system kitchen unit and the main body of the device. When the device main body is pulled out from the system kitchen unit and fits in the remaining space provided between the hose holding arm and the hose holding arm, the hose smoothly moves in the process of being pulled out and extended with the device main body. It had the drawback of not being able to move in a loop.

Therefore, the structure of the water supply hose and the intermediate joint of the present invention is shown in FIGS.
An intermediate joint 108 composed of 06 and a freely rotating nut portion 107 is connected between the water supply hose 100 and the water pipe 101.
