Conventionally, in a dishwasher of this type which is relatively small, the washing nozzle is provided at the bottom of the washing chamber, and the dishes supported by the basket are used for washing water jetted from below. Washed by. Further, since the dishwashing apparatus is relatively small, the washing room is small, and the limited space is effectively used by efficiently disposing the dishes in a basket. Specifically, the basket supports a relatively large tableware such as a large plate in a part (for example, a first half) and a relatively small tableware such as a small plate or a cup in another part (for example, a second half). At this time, the small plates, cups, and the like were efficiently arranged in a relatively narrow place by being supported in two stages.

However, when the dishes supported by the basket are washed by the washing nozzle provided at the bottom of the washing chamber, a relatively small tableware such as a small dish or a cup is supported in two vertical stages. In this case, there is a disadvantage that the tableware supported on the lower stage hinders the washing water from the washing nozzle from reaching the tableware supported on the upper stage, and the tableware supported on the upper stage is insufficiently washed.

Accordingly, as disclosed in Japanese Patent Application Laid-Open No. Hei 3-237793, in addition to the cleaning nozzle provided at the bottom of the cleaning chamber, another rod-shaped cleaning nozzle extending inward from one side wall of the cleaning chamber. May be provided. In this case, the basket supporting the tableware is prepared for supporting a large tableware and for supporting a small tableware, and the basket supporting the small tableware is placed above the other washing nozzle. A basket supporting a large dish is located in the washing chamber so as to be located between a washing nozzle provided at the bottom of the washing chamber and another washing nozzle. Thereby, large dishes are washed by the washing nozzle at the bottom of the washing chamber, and small dishes are washed by other washing nozzles, so that a sufficient washing effect can be obtained.

[0006]

However, in a relatively large dishwashing apparatus, a sufficient space for accommodating tableware is obtained in the washing chamber. However, if the small dishwasher as described above is provided with another washing nozzle extending into the washing chamber as described above, the washing chamber becomes extremely narrow, and a large dish There is a disadvantage that relatively large tableware such as the above cannot be stored or the number of tableware that can be stored is reduced.

The present invention has been made to solve the above-mentioned inconvenience, and an object of the present invention is to provide a relatively small dishwashing apparatus which can surely wash tableware supported in upper and lower stages without making the washing room narrow. Aim.
