Description

  The present invention relates to a drawer type dishwasher, and more particularly to a technique for housing a water supply hose and a drainage hose so that the water supply hose and the drainage hose can follow the slide of a washing tank without difficulty.

In the drawer type dishwasher, it is necessary to connect between the dishwasher main body and the washing tank with a water supply hose and a drain hose. In the drawer type dishwasher, the washing tank is pulled out from the opening provided in the front of the dishwasher body to store the dishes, and the washing tank is pushed back to a predetermined position in the dishwasher body for cleaning operation. Do. It is necessary to connect the water supply hose and the drain hose connected to the cleaning tank so as not to disturb the smooth sliding of the cleaning tank.
For this purpose, a technique is adopted in which the rear surface of the washing tub and the rear plate of the dishwasher main body are connected by a bendable water supply hose and a drainage hose. When the washing tub is housed in the dishwasher body, the water supply hose and drainage hose are folded so that they are housed in a small space between the rear plate of the dishwasher body and the back of the washing tub. To do.
The water supply hose and the drainage hose are extended or folded in accordance with the operation of pulling out or pushing back the cleaning tank. At this time, the water supply hose and the drainage hose may be forcibly extended, or may be crushed or twisted when folded. If the movement of the water supply hose and the drainage hose is not smooth, the drawer operation of the washing tank cannot be performed smoothly. Moreover, the durability of the water supply hose and the drainage hose is lowered by the stress applied to the water supply hose and the drainage hose.

  In order to solve the above problem, the dishwasher of Patent Document 1 includes a hose holder that holds a water supply hose and a drain hose. One end of the hose holder is swingably attached to the rear plate of the dishwasher body or the back surface of the washing tub. The hose holder rotates according to the operation of the washing tank being pulled out from the dishwasher body, and guides the water supply hose and the drainage hose to extend in a straight line. In addition, the hose holder is rotated according to the operation of pushing the washing tank back into the dishwasher body, and the water supply hose and the drainage hose are smoothly folded and guided. Since the hose holder guides how the water supply hose and the drainage hose are folded, the water supply hose and the drainage hose smoothly bend following the drawing operation of the cleaning tank, and the stress applied to the hose is reduced.

JP 2001-46308 A

In a conventional drawer type dishwasher, when the washing tub is pushed back to a predetermined position in the dishwasher body, the water supply hose and the drainage are placed in a narrow space between the rear plate of the dishwasher body and the back of the washing tank. The hose is accommodated. This space is narrow, and it is necessary to bend the water supply hose and the drainage hose sharply with a small radius of curvature in order to accommodate the space.
The space between the back plate of the dishwasher main body and the back of the washing tub is short, especially in the sliding direction of the washing tub. It is necessary to bend the hose sharply with an extremely small radius of curvature. If the hose is bent sharply with an extremely small radius of curvature, the durability of the hose is shortened. Therefore, a structure in which the water supply hose and the drainage hose are bent not only upward but also laterally is often employed. If the water supply hose and the drainage hose are bent upward and laterally, even if the water supply hose and the drainage hose are gently bent with a relatively large radius of curvature, Can be accommodated in a narrow space between.
However, in the system in which the water supply hose and the drainage hose are bent upward and laterally, the water supply hose and the drainage hose must be bent three-dimensionally, and the guide mechanism becomes difficult. In the method of bending the water supply hose and the drainage hose only upward, the water supply hose and the drainage hose are maintained in the same plane, so the guide mechanism is simplified. In order to accommodate in the narrow space between the back surfaces, it is necessary to bend the water supply hose and the drainage hose sharply with an extremely small radius of curvature, and the durability of the hose is shortened.

  In the present invention, the water supply hose and the drainage hose do not need to be bent three-dimensionally, and the guide mechanism is simplified because the water supply hose and the drainage hose need only be bent in the same plane. An object of the present invention is to provide a housing mechanism that eliminates the need for sharp bending at a radius.

The drawer type dishwasher of the present invention includes a dishwasher main body, a washing tub accommodated in the main body of the dishwasher, a water supply hose for supplying water to the washing tub, and a drain for the washing tub. A drain hose is provided. The drawer type dishwasher of the present invention is accommodated in a flat space between the inner surface of the dishwasher main body and the outer surface of the washing tank in a state where the water supply hose and the drainage hose are bent in the flat surface. Although the bent portion of the hose moves following the drawing operation of the cleaning tank, the radius of curvature of the bent portion is maintained at a certain radius or more.
If the water supply hose and the drainage hose are bent upward and laterally, even if the water supply hose and the drainage hose are gently bent with a relatively large radius of curvature, Can be accommodated in a narrow space between. However, it is difficult to create a guide mechanism for bending the water supply hose and the drainage hose three-dimensionally. In the method of bending the water supply hose and the drainage hose only upward, the water supply hose and the drainage hose are maintained in the same plane, so the guide mechanism is simplified. In order to accommodate in the narrow space between the back surfaces, it is necessary to bend the water supply hose and the drainage hose sharply with an extremely small radius of curvature, and the durability of the hose is shortened.
In the drawer-type dishwasher of this invention, a water supply hose and a drainage hose are accommodated in the flat space between the inner surface of a dishwasher main body, and the outer surface of a washing tank. The flat space between the inner surface of the dishwasher body and the outer surface of the washing tank is widely secured in the sliding direction of the washing tank even when the washing tank is housed in the dishwasher body. Yes. For this reason, in this flat space, a water supply hose and a drainage hose can be bent with a moderate curvature radius.
In the drawer type dishwasher of the present invention, the water supply hose and the drainage hose move the bent portion while keeping the curvature radius of the bent portion at a certain radius or more as the washing tank is pulled out. This can improve the durability without applying stress to specific portions of the water supply hose and the drainage hose.

In the drawer-type dishwasher of this invention, it is preferable that the water supply hose is accommodated in one flat space of the side of a washing tank, and the drainage hose is accommodated in the other flat space.
In this way, by distributing the water supply hose and the drainage hose to the flat spaces on the left and right sides of the cleaning tank, the flat spaces can be used effectively to the maximum. The degree of freedom of arrangement of the water supply hose and the drainage hose increases, and the radius of curvature of the bent portion can be increased.

In the flat space of the drawer type dishwasher of the present invention, the guide member for maintaining the radius of curvature of the hose bent portion at a certain radius or more is disposed so as to be movable in both the dishwasher body and the washing tank. preferable.

FIG. 7 is a schematic longitudinal sectional view of the drawer type dishwasher of the present embodiment, and is a view seen from the right side toward the front of the dishwasher. FIG. 7 shows a state where the washing tub is accommodated in the dishwasher body.
The structure of the drawer type dishwasher of a present Example is demonstrated. In addition, the dishwasher of a present Example is a modification of 3rd Example. Accordingly, the same parts as those of the third embodiment will be briefly described by omitting illustration, or the description thereof will be omitted. Moreover, the same code | symbol is used about the part similar to the dishwasher of 1st Example or 2nd Example.

As shown in FIG. 7, a washing tank 12 is accommodated inside the dishwasher main body 10. A door 14 is attached to the front portion (left side in FIG. 7) of the cleaning tank 12. The end portion 56a of the water supply pipe 56 is connected to the connection portion 12a on the side surface of the cleaning tank 12 (the right side surface facing the front of the dishwasher). A water supply valve 18 is provided in the middle of the water supply pipe 56. The water supply valve 18 is fixed behind the washing tank 12 in the dishwasher body 10. An end 56b of the water supply pipe 56 is connected to a water supply source. In addition, between the end part 56a of the water supply pipe 56 and the water supply valve 18 is a water supply hose 56c that can be bent and extended.
A guide member 50 for guiding the water supply hose 56 c is attached to the outer surface of the cleaning tank 12. The guide member 50 includes a support portion 50a, a slide portion 50b, a guide portion 50c, and a spring 50d. The guide member 50 is covered with a cover, but the illustration of the cover is omitted here for the sake of clarity. The support part 50a is attached to the side surface of the cleaning tank 12, and is a rectangular plate-like member. The upper side and the lower side of the support part 50a are folded back (referred to as a folded part). The slide part 50b is a plate-like member, and the upper edge and the lower edge are slidably held in the front-rear direction by the folded part of the support part 50a. A guide portion 50c is attached to the slide portion 50b. The guide portion 50c is composed of two plate members bent in an arc shape, and an interval is provided between the two plate members so that the water supply hose 56c can go back and forth without great resistance. In addition, a flange is formed at the front end of the slide portion 50b, and two springs 50d are attached vertically between the rear surface of the door 14 and the flange. The two springs 50d urge the slide portion 50b forward.

The configuration of the guide member 50 is very similar to the guide member 40 of the third embodiment. In the guide member 40 of the third embodiment, the water supply hose 46c is guided by the peripheral surface of the roller 40c, but in the guide member 50 of the fourth embodiment, the water supply hose 56c is formed in two arcuate shapes constituting the guide portion 50c. Are guided between the plate members. Although not shown, the dishwasher of this embodiment includes a guide member that guides the drainage hose on the outer surface opposite to the outer surface of the cleaning tank 12 in which the guide member 50 is disposed. Yes. The structure of the guide member that guides the drainage hose is the same member as the guide member 50 that guides the water supply hose 46c, and is very similar to the guide member 48 of the third embodiment. The guide member of the drainage hose of the fourth embodiment is replaced with two rollers constituting the guide portion in place of the roller 48c of the guide member 48 of the third embodiment, similarly to the guide portion 50c of the guide member 50 of the water supply hose 56c. It is guided by being sandwiched between arc-shaped plate members.
From the above, also in this embodiment, the same effect as the dishwasher of the third embodiment can be obtained. That is, also in the present embodiment, the guide member 50 of the water supply hose 56c is arranged on either the left or right outer surface of the washing tub 12, and the water supply hose 56c It is guided so as to be bent two-dimensionally in a flat space between the side surfaces. The drain hose guide member is disposed on the other outer surface of the washing tub 12, and the drain hose is disposed in the other flat space between the inner surface of the dishwasher body 10 and the outer surface of the washing tub 12. Guided to be bent in two dimensions. By these things, the water supply hose 56c and the drainage hose are guided without loosening while moving the position guided by the guide member in accordance with the drawing operation of the cleaning tank 12. Without bending the hose three-dimensionally, the bent portion can be moved in the flat plane while keeping the radius of curvature of the bent portion of the hose at a certain radius or more.

If the water supply hose and the drainage hose are bent upward and laterally, even if the water supply hose and the drainage hose are gently bent with a relatively large radius of curvature, Can be accommodated in a narrow space between. However, it is difficult to create a guide mechanism for bending the water supply hose and the drainage hose three-dimensionally. In the method of bending the water supply hose and the drainage hose only upward, the water supply hose and the drainage hose are maintained in the same plane, so the guide mechanism is simplified. In order to accommodate in the narrow space between the back surfaces, it is necessary to bend the water supply hose and the drainage hose sharply with an extremely small radius of curvature, and the durability of the hose is shortened.
In the drawer-type dishwasher of this invention, a water supply hose and a drainage hose are accommodated in the flat space between the inner surface of a dishwasher main body, and the outer surface of a washing tank. The flat space between the inner surface of the dishwasher body and the outer surface of the washing tank is widely secured in the sliding direction of the washing tank even when the washing tank is housed in the dishwasher body. Yes. For this reason, in this flat space, a water supply hose and a drainage hose can be bent with a moderate curvature radius. In the drawer type dishwasher of the present invention, the water supply hose and the drainage hose move the bent portion while keeping the curvature radius of the bent portion at a certain radius or more as the washing tank is pulled out. Therefore, without bending the hose three-dimensionally, it is bent with a radius of curvature of a certain radius or more, and further, the bent portion is moved, so that a large stress is not applied to a specific portion of the water supply hose and the drainage hose, Durability can be improved.

  Further, in any of the drawer type dishwashers of the first to fourth embodiments, the water supply hose and the drainage hose are distributed in the left and right flat spaces of the cleaning tank. Accordingly, the flat spaces on the left and right sides between the inner side surface of the dishwasher main body and the outer side surface of the washing tub on the left and right sides can be utilized to the maximum extent possible. The freedom degree of arrangement | positioning of a water supply hose and a drainage hose increases, and the curvature radius of a bending part can be taken more largely.

Further, a guide member that maintains the radius of curvature of the hose bent portion at a certain radius or more in the flat space of any drawer type dishwasher of the first to fourth embodiments also cleans the dishwasher body. The tank is also movably arranged. From this, the movement of the bent portion of the hose following the drawing operation of the cleaning tank can be performed more smoothly, and further, the drawing operation of the cleaning tank can be performed more smoothly.
Furthermore, in any of the drawer type dishwashers according to the first to fourth embodiments, the water supply hose is provided in the flat space on both the left and right sides between the inner surface of the dishwasher body and the outer surface of the washing tub. Guide members for guiding the drainage hoses are provided. By guiding the movement of the water supply hose and the drainage hose accompanying the drawing operation of the washing tank by the guide member, while maintaining a certain gentle bending angle of the water supply hose and the drainage hose,
In addition, although four types of guide members were described in the first to fourth embodiments, these are merely examples of guide members, and are not limited to these shapes and configurations.

Specific examples of the present invention have been described in detail above, but these are merely examples and do not limit the scope of the claims. The technology described in the claims includes various modifications and changes of the specific examples illustrated above.
