In this case, however, the dishwasher is provided with a guide section in the shape of a rectangular tunnel having a substantially rectangular cross section, and a separate support body attached to the dishwasher. The drainage pipe is guided by the guide portion and is supported by the support body.

[0003]

In the case of the above-mentioned conventional apparatus, the guide portion only guides the in-machine drainage pipe in a straight line, and the in-machine drainage pipe may be bent when coming out of the guide portion. If the in-machine drainage pipe is bent in this way, the drainage performance is impaired. To prevent this, a wire is wound around the outer periphery of the in-machine drainage pipe. But,
The in-machine drainage pipe around which this wire is wound is expensive, leading to an increase in product cost. Further, the attachment of the separate support is performed by screwing or the like, which is troublesome.

The present invention has been made in view of the above-mentioned circumstances, and therefore an object thereof is mainly to provide a dishwasher in which the guide and support of the in-machine drainage pipe is inexpensive and can be constructed without a trouble such as screwing. There is.

In order to achieve the above object, in the dishwasher of the present invention, an in-machine drainage pipe is connected to an existing outboard drainage pipe at the installation location, and is used. A guide part for guiding the in-machine drainage pipe having a curved portion and a support part for supporting the in-machine drainage pipe are integrally formed on the base plate.

In this case, both the guide part and the support part are preferably opened upward, and the guide part is preferably arranged to guide the in-machine drainage pipe to the middle position of the bent part.
Further, the guide part may have a rising slope toward the tip part, and the center position of the hole through which the in-machine drainage pipe at the base end part of the guide part is passed,
It may be higher than the center position of the connection port for connecting the in-flight drain pipe of the drain trap.

[0007]

According to the above means, the in-machine drainage pipe is bent while being guided by the curved portion of the guide portion, so that the bending can be prevented without winding the wire around the outer periphery. In addition, the guide portion and the support portion formed integrally with the base plate can be eliminated if the trouble of separately attaching them to the base plate by screwing or the like is unnecessary.

Further, in this case, particularly in the case where both the guide portion and the support portion are opened upward, it is possible to assemble them by simply fitting or mounting the in-machine drainage pipe from above, and Molding can also be easily performed by punching out upward. Further, in the case where the guide portion guides the in-machine drainage pipe to the middle position of the bent portion, the guide portion can be configured with the minimum necessary configuration.

When the guide portion has an ascending slope toward the tip, it is possible to avoid the formation of an extra water pool in the in-machine drainage pipe within the range guided by the guide portion. In addition, in that case, if the center position of the hole for passing the in-flight drain pipe at the base end of the guide part is set higher than the center position of the connection port connecting the in-flight drain pipe of the drain trap, from the drain trap to the guide part. Even in the range, it is possible to avoid the formation of an extra water pool in the in-flight drain pipe.
