SUMMARY OF THE INVENTION It is an object of the present invention to provide a dishwasher provided with a support structure for an upper basket that makes it easier to put dishes in a lower basket.

[0008]

Means for Solving the Problems According to the first aspect of the invention, there is provided an upper basket and a lower basket for accommodating tableware which are arranged in two stages in the washing room. The lower basket is a dishwasher integrally movable with respect to the washing chamber, the nozzle shaft being attached to the lower cage and guiding washing water upward, and mounted on the nozzle shaft. And an upper nozzle for ejecting the guided washing water to the upper cage, wherein the nozzle shaft supports the upper cage.

In this device, the upper cage is supported by a nozzle shaft attached to the lower cage. Further, the washing water guided upward by the nozzle shaft is jetted from the upper nozzle to the upper basket. Thereby, the dishes of the upper basket are washed. In addition, as long as the nozzle shaft is attached to the lower cage, the nozzle shaft may be located at substantially the center of the lower cage in plan view or may be biased to one side. The nozzle shaft may have a vertical posture or a posture inclined with respect to the vertical posture as long as the nozzle shaft is supported.

Here, as in the second aspect of the invention, "the upper cage is supported by the nozzle shaft and a piece extending upward from the lower cage at a position away from the nozzle shaft, and Can be freely moved toward and away from the nozzle axis. " And like the invention of claim 3,
"The piece part is fixed to an end of the lower basket on the direction of entry into the cleaning chamber, and the upper cage is connected to the piece part of the end on the side of entry and connected to the piece. That can be pivoted upward about the part ".

In this case, since the upper cage is rotatable upward around the connecting portion, the upper cage can freely move toward and away from the nozzle shaft. Further, when the upper car is rotated upward, the upper car moves in a direction away from the lower car. Further, as in the invention of claim 4,
In the case of "the upper end of the nozzle shaft and the bottom of the upper cage are fitted in the positioning state in the support state of the upper cage", an external force acts on the nozzle shaft and the upper cage in the support state. Also, these two do not shift.

As described above, according to the first aspect of the present invention, since the upper basket is supported by the nozzle shaft attached to the lower basket, the upper basket and the lower basket are pulled out of the washing chamber and lowered. When accommodating tableware in the basket, tableware can be put into the lower basket from the side as well, compared to conventional ones in which tableware cannot be put in from the side.
Tableware is easy to put in the lower basket.

Further, since the upper basket is supported by the nozzle shaft for guiding the washing water to the upper nozzle, a member for guiding the washing water and a member for supporting the upper basket are separately provided as in the related art. The configuration of the dishwasher is simplified as compared with the conventional one. According to the second aspect of the present invention, since the upper cage is supported by the nozzle shaft and the piece, the support state of the upper cage is more stable than that supported by only the nozzle shaft.

According to the third aspect of the present invention, when the upper basket is turned upward, the upper basket is separated from the lower basket. It is difficult to hit the upper basket, making it easier to put dishes in the lower basket. According to the fourth aspect of the present invention, even when an external force acts on the upper cage and the nozzle shaft, the two are not displaced from each other, so that the supporting state of the upper cage is further stabilized.
