The present invention relates to a washing machine, and more particularly, to a washing machine having an auxiliary basket that can be detachably installed in the rotating tank in the state where laundry is put.

In general, a washing machine is pre-programmed with washing, rinsing, drainage, and dehydration strokes in the microcomputer of the control unit, and is configured to allow the user to selectively control the washing machine. do.

The conventional washing machine having such a function includes a water tank in which water necessary for washing is stored in a housing forming an exterior, a rotating tank rotatably installed in the water tank and having a pulsator at a bottom thereof, a driving unit for driving the rotating tank and the pulsator, and the like. It consists of.

The tank is installed by hanging the suspension inside the housing, the lower part of which is equipped with a drive with a motor and a clutch. That is, the motor is mounted on the lower side of the tank, the clutch is fixed to the lower center of the tank and its shaft is coupled to the center of the rotary tank and the pulsator. Accordingly, power is transmitted only to the pulsator side by the clutch during the washing and rinsing stroke, and the pulsator and the rotating tub are simultaneously rotated during the dehydration stroke.

And the rotating tank disposed rotatably in the tank is made of a cylindrical shape with the upper portion is opened and the dehydration holes are perforated throughout the entire wall surface, the laundry is contained so that washing and dehydration is performed.

In the conventional washing machine configured as described above, a washing stroke, a draining stroke, and a dehydrating stroke are performed according to a command of a programmed control unit (not shown).

That is, when laundry and detergent are put into the rotating tank and the washing machine is operated by operating the control unit, the washing water is supplied and stored in the tank and power is applied to the motor.

Accordingly, during the washing and rinsing stroke, the pulsator rotates forward and backward by receiving the motor power through the clutch, so that the washing water flow is formed in the rotary tub, and the washing and rinsing stroke is performed.

After this stroke, the wash water stored in the tank is discharged out of the housing through the drain hose. Then, the rotating tank and the pulsator rotate at high speed in one direction, so that the dewatering stroke is performed.

However, in such a conventional washing machine, when the dehydration operation is completed, the laundry adheres to the inner wall of the rotating tub by centrifugal force, so that it is inconvenient to take out the laundry. In particular, this drawback is further revealed under the recent situation in which a large washing machine is preferred, and when a small amount of laundry is washed through the large washing machine, the rotating tub is deep and it is not easy to take out the laundry.

In addition, since the laundry proceeds while rubbing against the pulsator rotating forward and backward at a high speed, when the laundry is made of a soft material such as lingerie or a towel, it is frequently damaged by friction with the pulsator.

The present invention is to solve this problem, the object of the present invention is to install a detachable basket basket trap attached to the rotating tub to perform both washing and rinsing stroke and dehydration stroke in the state directly put the laundry, laundry It is to provide a washing machine with an auxiliary basket to prevent damage and at the same time easier to take out laundry.
