Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a dishwasher in which a leftover box for collecting leftover dishes washed out from the dishes housed in a washing chamber can be put in and taken out from the front surface of a main body casing.

[0002]

2. Description of the Related Art In the case of a dishwasher having a conventional front opening structure, when a dish box is taken out after a washing operation for disposal / washing, it is usually done through an open door of a washing room. Putting in and out is quite troublesome.

As a prior art capable of solving this problem, there is one disclosed in Japanese Patent Application Laid-Open No. 1-23132, which has a structure as shown in FIG.
A cleaning chamber B having an open front surface is provided at the upper part of the table, and a kitchen room C having an open front part is provided at the lower part, like the cleaning room B. further,
The upper part supports a rack E for storing dishes D, and
An upper drawer F for opening and closing the front opening of the cleaning chamber B
Is provided in the cleaning chamber B so as to be freely drawn out.

At the lower part, a lower drawer H for supporting a leftover container G for receiving leftovers falling from the rack E and for opening and closing the front opening of the leftover compartment C is pulled out to the leftover compartment C. Provide freely. The tableware D is placed on the rack E with both drawers F and H pulled out. At this time, the leftover food remaining on the tableware D is transferred from the rack E to the leftover food container G.
Drop it on. By pushing the lower drawer H into the leftover compartment C, the leftovers are stored in the leftover compartment C before the dishes D are washed. In this way, it is possible to omit the work of discarding the leftover dishes in a separate leftover dishes container or the like. The tableware D on which the leftovers are dropped is washed by the cleaning liquid jetting body J being sprayed with the cleaning liquid pumped from the cleaning liquid pump K.

[0005]

In the dishwasher shown in FIG. 10, the upper and lower drawers F and H are attached to the washing chamber B.
Further, the tableware D is placed on the rack E in a state where the tableware D is pulled out from the leftover room C, and the leftover food is dropped from the rack E into the leftover food container G. For this reason, it is necessary to pull out the upper and lower drawers F and H each time washing is performed to drop the residual food from the tableware D into the residual food container G, resulting in poor work efficiency.

[0006] In the residual food container G, only the liquid and the naturally falling objects that fall from the rack E are present. The long residual food caught on the rack E is hard to be removed by natural falling, and the efficiency of collecting the residual food is low. The treatment of residual food using liquid injection is not possible because it is an open type.

Further, during the cleaning operation, since the residual foods flow into the cleaning liquid tank, there is a problem that the cleaning liquid is heavily contaminated.

The object of the present invention is to solve the above-mentioned conventional problems and to enable the treatment of residual food by liquid injection.
It is an object of the present invention to provide a dishwasher that enhances the efficiency of collecting leftover foods, and at the same time, improves the operability for processing leftover foods by making the removal of the leftover food box simple.

[0009]

[0010]

According to the present invention, the damper 14 is closed and the washing chamber 2 is used during the preswer operation which is performed prior to the washing operation.
By spraying the cleaning liquid inside, the residual food adhering to the dishes and the like is swiftly and reliably washed away by the liquid spray, and passes through the damper 14 to the residual food container 15 in the residual food container storage unit 6. It flows down and is collected. During that time, the residual food does not flow into the cleaning liquid tank 5.

In the subsequent cleaning operation, the damper 14 is opened to store the cleaning liquid in which the dishes have been cleaned by spraying in the cleaning liquid tank 5, and is circulated again to be used for cleaning.

It is preferable that a lid is provided on the storage box 6 for the leftover food box and the lid is closed during the cleaning operation.

After the cleaning operation is finished, the flange 19 is unfixed, and the leftover food box 15 is pulled out from the opening 16 toward the front,
It can be taken out easily.

After discarding the leftover dishes and washing the boxes, the leftover boxes 15 are inserted through the openings 16 and the openings 19 are liquid-tightly sealed by the flanges 19, and at the same time, the leftover boxes 15 are fixed at a predetermined position. You can do it.
