Description

Soak washing method of washing machine}

The present invention relates to a soak washing method of a washing machine, and more particularly, to a soak washing method of a washing machine in which washing performance is improved and soaking time is reduced by optimizing the concentration of detergent during soaking.

In general, when a washing machine puts soiled clothing into a washing solution, the detergent separates the fibers from the fibers by the chemical action of the detergent, but the action of the detergent alone takes a long time, so that the speed of time of removal is increased by applying mechanical action such as friction or vibration. Will perform the action.

The washing operation control of the washing machine first detects the quantity of clothes and the like put into the washing tank, and when the quantity is determined, sets the water flow, the detergent, and the total washing time according to the quantity of the washing machine. The washing stroke is performed by vortexing water through the reverse rotation to separate the stains on the laundry by friction with the laundry.

Next, when the washing administration is completed, the turbid water is discharged and the fresh water is supplied from the washing tank to perform a rinsing cycle for rinsing for the number of times already set in the system. When the rinsing stroke is completed, the water in the washing tank is discharged and the induction motor is rotated at a high speed at a predetermined speed to remove the laundry water by centrifugal separation to perform dehydration stroke.

Meanwhile, the washing method includes a method of washing by a series of washing operations described above, and a method of performing a series of washing operations described above after performing a soaking washing in the case of heavily contaminated laundry. The washing is to be soaked while the water is supplied to the contaminated laundry at the same time and the detergent is added and soaked as it is for a predetermined time, or the pulsator or the washing tank is intermittently driven.

In the washing method of the conventional washing machine according to the prior art, the washing water is first supplied in the first step until the washing water level (H) is reached in the washing tank into which the laundry and the detergent are added. (See S1 and S2)

In the second step, the washing water at the washing water level (H) is stirred in the first step after supplying water to the pulsator or the washing tank for a predetermined time (T1) to dissolve the detergent and to simultaneously infiltrate the detergent into the laundry. Isolate light contamination while allowing to increase (see S3 and S4).

In the third step, the pulsator or the washing tank is stopped or intermittently driven after the set time T1 has elapsed, and the laundry is called during the set time T2 (see S5 and S6).

Finally, when the soaking is completed during the set time T2 in the third step, the washing stroke, rinsing stroke and dehydration stroke described above are performed (see S7).

However, in the conventional soaking method, since the soaking proceeds while leaving the contaminant separated from the laundry while the soaking washing is performed, the laundry is recontaminated by the contaminant separated from the laundry, thereby impairing washing performance. There is a problem.

In addition, there is a problem that the soaking time is increased because the soaking is continuously performed during the set time even though the soaking is not necessary anymore.

The present invention has been made to solve the above problems of the prior art, the object is to divide the number of wash water supplied to the washing tank during the soaking washing to reach the washing water level in a plurality of stages and at each stage pulsator or washing tank By dissolving the detergent through agitation to optimize the concentration of the detergent and soaking washing is to provide a soaking washing method of the washing machine not only to improve the washing performance, but also to reduce the soaking time.
