In order to achieve the above object, the washing machine for combined use of dehydration of the present invention comprises a tub having a dehydration hole only in the upper portion, and water is stored in the tub for washing. In the one that is dehydrated from the dehydration hole by rotating the tank, the tank is press-formed by a metal plate in an inclined shape in which only the groove extending from the lower portion to each dehydration hole portion gradually increases the depth. The other part of the peripheral side portion is formed in a straight shape.

In this case, the groove may be formed up to the dehydration hole portion of the tank, and the portion above the tank may be formed in a circular shape.

Further, the portions on both sides of the groove may be formed so as to be inclined toward the groove.

[0009]

According to the above means, only the groove extending from the lower portion to each of the dehydration hole portions in the upper portion of the tank is press-formed into an inclined shape with the depth gradually increasing, and the other portions of the peripheral side portion are formed in the straight shape. Therefore, it is a water-saving type that stores water only inside the tub for washing, and it can be drained well through the groove with good pumpability, but its material plate shape can be rectangular. It is possible to improve the material collection of.

Further, in this case, if the groove is formed up to the dehydration hole portion of the tank and the portion above the tank is formed in a circular shape, the strength against external force from inside and outside in the radial direction of the tank can be maintained high. .

Further, in the case where the portions on both sides of the groove are formed in a slanted shape so as to drop toward the groove, water to be dehydrated can easily enter the groove, and the dehydration rate can be further increased.
