EXAMPLE III

The present embodiment is based on the first and second embodiments, and further has the following distinguishing technical features: the inner cylinder 1 of the washing machine is not provided with a normally open through hole, so that the inner cylinder 1 forms a sealed water container when the washing machine is in a washing state, washing water only flows in the inner cylinder 1, the washing machine forms a hole-free inner cylinder washing machine, and the phenomenon that the washing water flows between the inner cylinder and the outer cylinder in a cross mode is thoroughly avoided when the washing machine washes.

In addition, the washing machine in this embodiment may be any one of the prior art that has a door to close the opening 101 of the inner tub and then the inner tub 1 forms a sealed container, so that when the washing machine performs a dehydration process, the inner tub 1 is controlled to rotate at a high speed to smoothly discharge the water flow in the inner tub 1, which is separated from the clothes, out of the inner tub 1, thereby achieving the purpose of normally performing the dehydration process on the washing machine with a non-porous inner tub. Therefore, the washing machine in the embodiment of the present invention is not limited to the structure shown in the drawings, for example: the existing common washing machine is adopted, and only the washing machine inner barrel 1 is required to be set to be a washing machine which does not have a dehydration hole and forms a sealed container after the inner barrel opening is closed by the door cover 4. Meanwhile, a sealed container is formed after the inner barrel 1 is buckled with the door cover 4 and when the washing machine washes clothes, so that the clothes only contact with washing water in the sealed inner barrel 1 in the washing process, the phenomenon that the washing water between the inner barrel and the outer barrel flows into the inner barrel to pollute the clothes is avoided, the washing cleanliness of the washing machine is greatly improved, and the phenomenon that the clothes are not thoroughly washed by the washing machine due to the pollution of the washing water between the inner barrel and the outer barrel is avoided.

In the embodiment, in order to discharge the water flow after the clothes in the inner barrel 1 of the washing machine are separated and realize the normal washing of the inner barrel 1 sealed with water in the working process of the washing machine, the following settings are carried out:

the inner cylinder 1 is provided with a washing normally closed hole, so that in the normal washing and rinsing processes of the inner cylinder 1, when the rotating speed of the inner cylinder 1 is lower than a set value, the washing normally closed hole is closed, the inner cylinder directly forms a water containing cylinder for containing washing and rinsing water, and the washing and rinsing water heavily retained by the inner cylinder is used for washing or rinsing clothes; when the rotation speed of the inner cylinder is higher than a set value in the process of performing dehydration and drainage by the inner cylinder, the normally closed washing hole is opened, so that water in the inner cylinder directly flows out through the normally closed washing hole.

In this embodiment, the washing normally closed hole includes: the hole is arranged on the inner cylinder 1 and is arranged in a penetrating way so as to allow water flow to pass through; the centrifugal valve is arranged on the inner barrel 1 and correspondingly arranged at the hole, the valve core of the centrifugal valve is used for plugging the hole, and the valve core of the centrifugal valve is opened under the action of centrifugal force after the rotating speed of the inner barrel reaches a set value. Preferably, the centrifugal valve further comprises an elastic member, and the elastic member is clamped between the valve core and the inner cylinder to provide a reset acting force for the valve core so as to push the valve core to block the hole. The centrifugal valve can be any valve body structure which can open the hole under the action of centrifugal force in the prior art.

Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
