Description

Washing machine {A washing machine}

The present invention relates to a washing machine, and more particularly, to a washing machine capable of supplying water to the edge of the rotary tub in a shower method during a rinsing dehydration stroke.

In general, a washing machine is pre-programmed with washing, rinsing, draining and dehydrating strokes in the microcomputer of the control unit, and is configured so that the user can control the program, and the laundry is automatically washed through a series of programmed processes. do.

A conventional washing machine having such a function includes a water tank for storing a certain amount of water in a housing forming an external form, a conventional water tank rotatably mounted in the water tank, and a dewatering hole is drilled over the entire wall surface, and the normal and reverse rotation at the bottom of the water tank. It has a pulsator installed wherever possible.

And the upper cover is coupled to the upper cover consisting of a plurality of operation buttons to control the drive of the washing machine. The upper cover is coupled to cover the open upper part of the housing, which includes an inlet formed to put or take out laundry, and a detergent supply for supplying detergent to the rotating tub together with water supplied to the inlet and supplied through the water supply valve. The device is provided.

In addition, the detergent supply device is fixed to the inside of the upper cover and the water supply casing associated with the water supply valve side, the water supply casing drawer type access to the detergent box into which detergent is introduced. The detergent box is opened at the top, and water supplied from the water supply valve is introduced, and a discharge port is formed at the bottom of the detergent box so that water and detergent are discharged.

Therefore, if the laundry is put in the rotating tank and the detergent is put into the detergent box and the washing machine is operated, the water supplied through the water supply valve is discharged to the rotating tank together with the detergent. And when an appropriate amount of water is stored in the bath, further water supply is stopped and the pulsator is rotated forward and backward to perform washing by the dissolved detergent and frictional force. Then, after the washing stroke is performed by the user's selection control, the rinsing and the dehydrating stroke are continuously performed.

During these various administrations, the washing administration proceeds with water supply, washing, draining and dehydration, and the rinsing administration proceeds with water supply, rinsing, draining and dehydration. At this time, since the rinsing stroke is performed by pulsator rotation in the state of filling the rotary tank with water, a large amount of water is required. Moreover, since two or more rinsing cycles are usually performed to ensure laundry rinsing, a significant amount of water is required.

Therefore, in recent years, the so-called "rinse dehydration method" that can increase the rinsing effect while reducing the water consumption has been proposed. This "rinse dehydration method" is to perform the primary rinsing by supplying water while slowly rotating the rotary tank during the rinsing stroke. That is, since water is supplied along with the rotational movement of the rotating tub, the washing is primarily rinsed at the same time as the water supply proceeds. Therefore, a small amount of water can be used to efficiently rinse the laundry.

However, in such a conventional washing machine, when the "rinse dehydration method" proceeds, water falls like a waterfall into a specific part through the detergent supply device, so that the laundry cannot be rinsed uniformly.

In particular, the laundry is driven to the edge of the rotary tub by the rotary motion of the rotary tub, water is dropped to the center of the rotary tub through the outlet of the detergent supply device. Therefore, the laundry position and the water supply direction are shifted from each other, and thus there is a limit to improving the laundry rinsing effect.

The present invention is to solve such a problem, an object of the present invention is to improve the detergent supply device for supplying the detergent to the rotating tank side with water flowing from the outside, in the rinsing dehydration stroke to shower the water in the rotary tank edge region It is to provide a washing machine that can further improve the laundry rinsing power by uniformly distributed supply in a manner.
