Abstract
The present invention relates a washing machine having a floatage clutch for performing the conversion of a cleansing step and a dehydrating step. This floatage clutch can be actuated only by using floatage and gravity to be generated during the feeding/draining of water without a separate driving part. Accordingly, the construction of clutch part can be simplified, and consequently the cost of manufacturing of the washing machine can be reduced.
Claims12
A washing machine comprising:
- a water tub;
- a cleansing basket rotatably contained within the water tub;
- a pulsator rotatably mounted on the bottom surface of the cleansing basket, having a wing part for forming a water stream, a hub part disposed in the center of the wing part, and a hollow shaft part protruded from the bottom of the hub part exceeding the cleansing basket downwardly;
- a driving motor for generating a driving force required to rotate the cleansing basket and the pulsator;
- a transmission for transmitting the driving force of the driving motor to the cleansing basket and the pulsator, having a hollow dryer shaft integrated to the cleansing basket;
- and a washing shaft penetrating the hollow dryer shaft, of which the upper end passes the hollow shaft part of the pulsator and then is fixed to the hub part, and of which the lower end is connected with the driving motor;
- and
- a floatage clutch for allowing the cleansing basket to selectively cooperate with the pulsator by being intermittently actuated depending on the existence and nonexistence of water, having a float engaged with the washing shaft to be capable of moving up and down due to floatage, and a fixed member fixed to the upper end of the hollow dryer shaft to be separated from and coupled with the float at the lower side thereof.
