Thus, the bridge piece 39 does not deform due to the weight of the tableware basket 29 passing over the bridge piece 39.

In the guide body 36L, a front end portion formed between the front end surface and the inner side surface (an end portion facing the left rib 33L).
The inner corner 36a is provided with a radius, and the rear end face 36b has an acute angle (eg, 30 degrees) from the outer face.
It is formed on the slope so that The left rib 33L
In the above, R is provided at a corner 33a inside a lower end (an end facing the guide body 36L) formed by the lower end surface and the inner side surface. In the present invention, the corners 36a of the guide body 36L and the corners 33a of the left rib 33L may be chamfered, instead of providing R, as long as the corners are reduced.

The right auxiliary part 37R detachably attached to the front end of the right mounting table 31R is symmetrical in shape with the left auxiliary part 37L, and the right guide body 36 is provided.
R also has a left-right symmetric shape with the left guide body 36L. Therefore, a detailed description of the right auxiliary part 37R and the right guide body 36R is omitted here.

As shown in FIGS. 2 and 5, the inner surface of the guide body 36 is substantially flush with the inner surface of the guide rib 33 when the guide body 36 is mounted on the mounting table 31. In addition, as shown in FIG.
Is stored at an appropriate position in the washing room 3, the front roller 30 </ b> F of the tableware basket 29 is placed at a position guided by the guide body 36, and the tableware basket 29 is completely placed on the back surface of the door 7. In the pulled-out state, the rear roller 30R of the tableware basket 29 is brought to a position where it is guided by the guide body 36.

Thus, in the above configuration, since the inner surface of the guide body 36 is substantially flush with the inner surface of the guide rib 33, when the tableware basket 29 is pulled out of the washing room 3 to the back surface of the door 7, The front roller 30F is the guide rib 33
Can be prevented from being caught on the lower end of the cover. Further, when the front roller 30F moves on the back surface of the door 7, the tableware basket 29 is moved.
If the rear roller 30R deviates slightly from the predetermined trajectory without being pulled out straight, the rear roller 30R may move forward toward the side wall of the cleaning chamber 3, that is, outside the inner surface of the guide body 36. . In this case, finally, as shown in FIG. 5, the rear roller 30R hits the rear end face 36b of the guide body 36, but the rear end face 36b guides the rear roller 30R inward by the slope to guide the rear body 30R. It is moved inside the body 36. Therefore, the rear roller 3
It is also possible to prevent 0R from being caught on the guide body 36. Therefore, the tableware basket 29 can be pulled out smoothly.

Further, the inner corner 3 of the front end of the guide body 36
Since R is provided in 6a, even when the front roller 30F slightly hits the corner 36a when the tableware basket 29 is placed in the washing room 3, the tableware basket 29 is not caught. Further, since the corner 33a at the lower end of the guide rib 33 is also provided with an R, even when the front roller 30F slightly hits the corner 33a when the tableware basket 29 is pulled out from the washing chamber 3, the tableware basket 29 is not caught. . Accordingly, the tableware basket 29 can be more smoothly pulled out, and the tableware basket 29 can be smoothly accommodated in the washing room 3.

Further, since the guide member 36 is detachably fixed in the form of a part of the auxiliary component 37, even if the guide member 36 is worn out while repeatedly hitting the roller 30, it can be easily replaced. it can.

Note that the present invention is not limited to the above configuration. For example, when the tableware basket is placed at an appropriate position in the washing room, the front roller is positioned farther than the guide body. Is also good. Also, the rear roller may come out to the back surface of the door when the tableware basket is completely pulled out to the back surface of the door. In this case, by pulling out the tableware basket in a state where the front roller is out of the predetermined track in the cleaning chamber, even if the front roller hits the rear end surface of the guide body, it is guided by the slope and moves inside the guide body, Further, it is guided by the guide body and moves to the back surface of the door. Therefore, even with such a configuration, the tableware basket can be pulled out smoothly.

However, considering that the roller does not hit the guide member as much as possible, it is desirable that the front roller is placed at a position where the front roller is guided by the guide member in a state in which the dish basket is stored in an appropriate position in the washing room. In addition, we want to pull out the tableware as far as possible, but if the rear roller comes to the back of the door, the whole weight of the tableware and the tableware basket will be applied to the door, and there is a risk of damage to the shaft of the door. When the tableware basket is completely pulled out to the back of the door, it is desirable that the rear roller be brought to a position where it is guided by the guide body.

[0039]

According to the structure of the present invention, the inner surface of the guide body is substantially flush with the inner surface of the guide rib.
When the tableware basket is pulled out from the washing room to the back side of the door, the roller can be prevented from being caught on the lower end of the guide rib. In addition, even if the roller comes into contact with the rear end face of the guide body by moving the mounting table in a state where the roller is out of the predetermined track, the rear end face guides the roller inward by the slope, and the inside of the guide body is inclined. Move to. Therefore,
The roller can be prevented from being caught on the guide body. Therefore, the tableware basket can be pulled out smoothly.

Furthermore, since the inside corner of the end of the guide body facing the guide rib is angled, even when the roller slightly hits the corner when the dish basket is placed in the washing room, the dish basket will not be caught. Therefore, the tableware basket can be smoothly accommodated in the washing room.

Further, since the corners inside the ends of the guide ribs facing the guide body are angled, even when the roller slightly hits the corners when the tableware basket is pulled out of the washing room, the tableware basket is not caught. Therefore, the tableware basket can be more smoothly pulled out.

Further, since the guide member is formed separately and is detachably fixed to the mounting table, the guide member can be easily replaced even if the guide member is worn out while repeatedly hitting the roller.
