Description

Water saving type washing machine

The present invention relates to a washing machine, and more particularly, to a water-saving washing machine that can save the wash water used during washing.

In general, a washing machine is mainly for washing clothes by a mechanical operation through an electric motor. The washing machine includes a washing part performing a washing operation and a driving part driving a washing part. The washing method includes an agitator type and a washing method. It is divided into drum type and pulsator type.

Among them, the washing unit of the spiral wound washing machine, as shown in FIG. 1, has a reservoir 12 installed in the case 10, a washing tank 14 rotatably embedded in the reservoir 12, and a pulse forming water flow at the bottom of the washing tank. It comprises a data 16 and a supply drain valve 17, 18, the washing tank 14 is a form in which a plurality of dehydration holes (14a) is provided on the wall by the drive motor (20) It is mounted in a rotatable structure.

The drive unit 20 includes a drive motor 20, a transmission device 30, a clutch mechanism, and brake means for rotating the pulsator 16, the washing tank 14 by receiving the driving force of the drive motor 20. consist of.

The washing process by the spiral winding washing machine configured as described above is a water supply stroke in which the washing water is supplied into the washing tank 14 by the water supply valve 17, and the rotation of the pulsator 16 after the water supply stroke is finished. Washing cycle that rotates for a certain time, and after the wash stroke drains the wash water through the drain valve 18, and then rinsing stroke to rinse the laundry for a predetermined number of times by supplying clear water, that is, rinsing water containing no detergent, and rinsing After the stroke is completed, the washing tank 14 is rotated at a high speed to dehydrate the laundry.

In the water supply stroke, the water flowing through the water supply valve 17 passes through the detergent container, and the washing water mixed with the detergent is supplied. In the washing stroke, the physical action of the pulsator 16 is accompanied by the chemical reaction of the detergent contained in the wash water. The washing process proceeds by removing the contaminants on the clothes by the action. At this time, the pulsator 16 repeats the normal and reverse rotation in which the rotation direction is intermittently reversed by the transmission 30, and then the left and right water flow and the vertical direction. The water flow combines to form a bidirectional water flow to achieve a cleaning action.

Subsequently, in the ongoing rinsing stroke, the detergent component in the laundry is removed by bidirectional water flow generated by the rotational operation of the pulsator 16 as in the washing stroke in the state where the rinsing water is not mixed with the detergent. In the stroke, after the rinsing water is drained, the washing tub 14 is rapidly rotated in one direction, so that the water of the laundry is centrifugal by the centrifugal force while the laundry is in close contact with the inner wall of the washing tub 14.

In the dehydration stroke, the washing tank 14 and the pulsator 16 are rotated in the same direction at the same time to prevent the clothes from being damaged by the pulsator 16, and the drain valve 18 is opened to dehydrate the washing tank 14. The water discharged through the ball 14a is drained to the outside of the washing machine.

On the other hand, according to the prior art as described above, the amount of wash water supplied in the washing process is changed in proportion to the amount of washing, the wash water supplied to the washing tank 14 in the water supply stroke of the washing tank 14 in which the dehydration hole (14a) is formed. The structure does not stay only in the washing tank 14, but is discharged to the outside of the washing tank 14.

Therefore, in order to ensure that the wash water level in the washing tank 14 reaches a predetermined value, the washing water must be supplied based on the storage tank 12 rather than the washing tank 14, so that the washing operation in the actual washing tank 14 is performed. It requires much more wash water than is needed to do.

That is, the washing machine according to the prior art as described above has a problem in that the economic efficiency is reduced by the consumption of a larger amount of washing water than actually needed during the washing process.

The present invention has been made to solve the above-mentioned conventional problems, the structure is provided with a basket-type pulsator that can store a small amount of wash water, when the feeling of washing is less, so that the laundry water can be stored only in the basket-type pulsator It is an object of the present invention to provide a water-saving washing machine that can save washing water.

At this time, the clutch 56 is in a detached state in which the hollow dewatering shaft 52 and the washing shaft 54 are not connected, and the washing tank 40 is the washing shaft 54 and the hollow dewatering shaft 52 by the reduction gear means. ) Rotates in the opposite direction to the basket-type pulsator 42, but does not affect the washing action.

In the small amount of washing mode, only the washing water required for washing is consumed due to the structure of the basket type pulsator 42, and the basket part 421 and the pulsator part 422 rotate together so as to be relatively soft by the washing method. Since the water flow is formed, it is possible to efficiently wash the light and soft texture of the laundry.

After the washing stroke is finished, the washing water is drained through the drain valve provided on the bottom surface of the basket 422, and the rinsing stroke and the dehydrating stroke are performed. In the dehydrating stroke, the basket-type pulsator 42 moves in one direction. In a state in which the clothes are quickly rotated so as to be in close contact with the inner wall of the basket 421, the water of the clothes goes up the inner wall of the basket 421 by the centrifugal force and is discharged to the washing tank 40.
