Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to general box-shaped appliances around a kitchen such as a dishwasher and a dish dryer, and more particularly to external dimensions thereof.

[0002]

2. Description of the Related Art Recently, dishwashers are gradually becoming popular in Japan. As a place for arranging such a dishwasher, it is common to incorporate a dishwasher under the top plate near the sink, and in order to set dishes in such a dishwasher, it is impossible to bend over. However, in order to wash the dishes with the dishwasher, the dirty dishes are washed away before being set in the dishwasher, which causes a problem of water dripping on the floor. Therefore, as a measure for solving the above problems, it is considered to use the dishwasher by arranging it as close as possible to the sink of the system kitchen of the kitchen.

However, the conventional dishwasher has the following problems when it is arranged as close as possible to the sink of the system kitchen. In conventional dishwashers, the installation direction and position are almost uniquely determined, and there is little freedom to adopt a convenient installation method. In the conventional dishwasher, the required installation surface is approximately W450 x D
In many cases, it cannot be placed near the sink of the system kitchen because 500 is required. When the conventional dishwasher is placed near the sink of the system kitchen, there is no extra space around the installation area and the cooking space is pressed. Even if the conventional dishwasher is arranged near the sink, when the actual dishwashing work is performed, it is difficult to perform the work in the direction of the flow line of the work, and there is a large amount of water dripping on the floor.

By the way, the BL standard (the product standard relating to the "dishwasher and dryer" that makes Better Living Foundation) is applied to the dishwasher. According to the BL standard, the tableware shown in FIG. , A standard type dishwasher for a family of 4 is required to have the capacity to store this for 4 people. Based on the contents of the BL standard shown in FIG. 8, the platter is φ230 ± 10 m.
m, middle plate φ is 180 ± 10 mm, such heavy dishes will be stored in the lower part of the dishwasher, and the widthwise (W direction) dimension of the dishwasher can be reduced. As shown in FIG. 9, a plate 21 is attached to the lower part 20 of the dishwasher.
Also, the inner plate 22 is stored in an upright state. Therefore, the dimension of the dishwasher shown in the drawing in the depth direction (L direction) must be at least 230 mm + 180 mm = 410 mm.
In that case, in the conventional dishwasher shown in FIG. 10 and FIG. 11, since the storage part 23 such as the water pipe 6 for the nozzle 4 is provided at the innermost portion in the L direction, as a result, the depth direction of the dishwasher ( There was a problem that the dimension in the L direction) was excessive.

Further, as shown in FIGS. 10 and 11, a housing portion 24 is provided at the bottom of the dishwasher main body,
As shown in FIGS. 12 and 13, the accommodating portion 24 accommodates a storage tank 25 for storing the cleaning water sprayed from the nozzles and a circulation pump 26 for circulating the storage water stored in the storage tank 25 to the nozzles. To be done. In order to secure the injection flow rate (circulation flow rate) ejected from the nozzle 4 to the extent necessary for cleaning, the circulation pump 26 arranged in the accommodating portion 24 needs to have a sufficient capacity. Two
6 is large enough to satisfy the capacity. Conventionally, the arrangement of the circulation pump 26 and the storage tank 25 in the storage section 24 described above is as shown in FIG.
It is common to arrange a storage tank 25 for storing the cleaning water on the top, and by doing so, the water supply pipe 25a from the storage tank 25 to the circulation pump 26 and the cleaning water stored in the storage tank 25. The distance X from the water surface is sufficiently secured to prevent the air from being entrapped in the pump. But,
In that case, there is a problem in that the height h of the accommodating portion shown in the figure becomes excessively large, but on the other hand, a lot of useless space is generated in the dishwasher.

Further, as shown in FIG. 12, a pump housing portion 24
There is also proposed an example of arranging so as to project upward from the storage tank 25 that stores the cleaning water. However, even in this case, the problem that a large amount of useless space is generated in the dishwasher described above cannot be solved, and there is a risk that air will be trapped. That is, in the case of each of the above conventional techniques, the dishwasher is made compact, and at the same time, the amount of water required for washing (3 to 5 l) is secured, and a sufficient water depth for preventing air suction from the pump is secured. It was difficult.

[0007]
