[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing machine for washing laundry put in a washing and dewatering tub.

[0002]

2. Description of the Related Art Conventionally, a washing machine is constructed as shown in FIG. Hereinafter, the configuration will be described.

[0003] As shown in FIG.
A stirring blade 2 is rotatably arranged on the bottom surface, and a water receiving tank 3 is provided outside the washing and dewatering tank 1. A motor 4 for driving the washing / dewatering tub 1 and the stirring blade 2 is attached to the bottom surface of the water receiving tub 3, and the washing / dewatering tub 1 or the stirring blade 2 is driven via a clutch device 5 for switching the driving unit. It is configured to do. The water receiving tank 3 is supported on the outer frame 6 via a suspension 7 in a vibration-proof manner. A fluid balancer 8 containing a liquid is fixed to an upper portion of the washing and dewatering tub 1. The upper surface of the water receiving tank 1 is covered with a water receiving tank cover 9.

In the above construction, in the washing process, the washing liquid is put into the water receiving tub 3 and the laundry (clothes) put into the washing and dewatering tub 1 is stirred by the stirring blades 2 so that the washing liquid penetrates the laundry. Remove dirt by letting through and rubbing laundry.
In the rinsing process, water is poured into the water receiving tub 3 and stirred by the stirring blades 2 to rinse the laundry. In the dehydration step, the clutch device 5 is switched to transmit the rotation of the motor 5 to the washing and dewatering tub 1, and the washing and dewatering tub 1 is rotated to centrifugally dehydrate the laundry.

[0005] Each of these steps is sequentially controlled so that washing, rinsing, and dehydrating steps are automatically performed.

[0006]

In such a conventional construction, the washing capacity has recently been increased, and the washing capacity has been increased to 8%.
Some are over kg. For this reason,
In order to make the washing liquid permeate the entire laundry in the washing and spin-drying tub 1 and transmit the rotation of the stirring blade 2 to the entire laundry, the rotation force of the stirring blade 2 is increased or the stirring force is increased. As a result, as a result,
There is a problem that the laundry (clothing) is also damaged and the laundry is entangled.

The present invention solves the above-mentioned conventional problems, and circulates the washing liquid without applying mechanical force such as a stirring blade to the laundry in the washing and dewatering tub, thereby damaging the laundry, The purpose is to be able to wash without getting entangled.

[0008]

According to the present invention, in order to achieve the above object, a washing and dewatering tub is rotatably disposed in a water receiving tub, and the upper portion of the water receiving tub is covered with a water receiving cover, and the washing and dewatering is performed. By the pumping action of rotating the spin-drying tub by the driving means, the washing liquid between the spin-drying tub and the water receiving tub is moved from between the spin-drying tub and the water-receiving tub cover to substantially the center of the spin-drying tub. And water is stopped by a packing member such as a sponge material or a rubber material between the water receiving tank and the water receiving tank cover.

[0009] Thus, by circulating the washing liquid without applying mechanical force such as stirring blades to the laundry in the washing and dewatering tub, washing can be performed without damaging or tangling the laundry. Washing can be performed without worrying about spouting of water, splashing of water, and the like.
