Washing method of washing machine {Washing method of a washer}

The present invention relates to a washing method of a washing machine in which washing is performed while an appropriate amount of washing water is supplied into an inner tank and an outer tank, and a pulsator is rotated. Particularly, a pulsator and It relates to a washing method of the washing machine so that the inner tank is rotated to perform the centrifugal washing.

In general, a washing machine is a machine that removes stains on clothing by providing a mechanical action using electricity.When it is put on clothing, it is removed from the fibers by the chemical action of detergent when put in the washing liquid, Because it takes time, if the water flow is forcibly generated and mechanical action such as friction or vibration can be removed quickly and easily.

1 is a side cross-sectional view showing a general washing machine.

In general, the washing machine is installed to hang inside the cabinet (2) forming the exterior as shown in Figure 1, the outer tank (4) in which the wash water is contained, and rotatably installed inside the outer tank (4) and wash water and An inner tub 6 in which laundry is contained and washed, a pulsator 8 rotatably installed on a bottom surface of the inner tub 6 to form a rotational flow in the inner tub 6, and a lower portion of the outer tub 4. It is installed to be connected to the inner tank 6 and the pulsator (8) is configured to include a motor (10) for rotating the inner tank (6) or pulsator (8).

Of course, the water supply valve assembly 12 and the detergent box assembly 14 including a water supply valve (not shown) for supplying the washing water together with the detergent to the outer tank 4 and the inner tank 6 on the cabinet 2. Is built-in, the lower one side of the outer tank 4 is installed so that the drain valve assembly 16 for draining the outer tank 4 and the washing water of the inner tank is connected.

Here, the motor 10 transmits power only to the washing shaft 8a connected to the lower center of the pulsator 8, or the dehydration shaft 6a connected to the lower center of the inner tub 6 is A clutch (not shown) is configured to be engaged with the washing shaft 8a so as to simultaneously transmit power to the washing shaft 8a and the dewatering shaft 6a.

Then, an upper side of the inner tank 6 is provided with a ring-shaped auto balance mechanism 6a for balancing the inner tank 6 so as not to hit the outer tank 4 due to the bias of the laundry, and the outer tank 4 On the upper side of the inner tub (6) by the centrifugal force of the washing water rising along the inner wall surface of the outer tank (4) is provided with a ring-shaped tub cover (4a) to be sprayed to the upper side of the inner tank (6).

Looking at the conventional washing method of the washing machine configured as described above, while the pulsator (8) is stirred while the laundry is put into the inner tank (6), the amount of water is sensed, the water valve assembly (12) and detergent box assembly ( Through 14), the washing water is supplied with the detergent up to the washing level set according to the quantity.

Here, the detergent is dissolved in the wash water while only the pulsator 8 is rotated while the wash water is supplied to a level lower than the wash level while the wash water is supplied to the wash water level set in the inner tank 6 and the outer tank 4. In addition to this, the packing of laundry is carried out.

Then, when the wash water is supplied to the washing water level in the inner tank 6, the washing is stopped while the water supply of the washing water is stopped and the pulsator 8 is rotated.

At this time, the inner tub 6 is rotated in the opposite direction to the pulsator 8 while the pulsator 8 is rotated, or the pulsator 8 and the inner tub 6 are rotated at the same time so that the outer tub (4) Centrifugal washing to cause washing water rising along the inner wall surface to hit the tub cover 4a and to be sprayed onto the inner tank 6 again, thereby improving washing performance.

However, the washing method of the washing machine according to the prior art is a lot of time for the detergent dissolution and weeping because the detergent dissolving and weaving is made while only the pulsator (8) is rotated in a state where a relatively small amount of washing water is watered In this case, when laundry is introduced to spread on the upper side of the pulsator 8, the washing performance is deteriorated because it is not rubbed by the inner tank 6 as it is rotated at the same time as the pulsator 8.

The present invention has been made to solve the above-mentioned problems of the prior art, it is only to make the detergent dissolution and packing in the state in which the washing water is supplied to the minimum water level lower than the washing water level set according to the amount in the inner tank and the outer tank. It is not an object of the present invention to provide a washing method of a washing machine to smoothly circulate laundry.

In the washing method of the washing machine according to the present invention for solving the above problems, laundry is contained in the inner tank and the outer tank, and the washing water level is set according to the amount of water while the pulsator installed on the bottom surface of the inner tank is stirred and the amount of water is sensed. And a second step of washing the water to the minimum level inside the inner tank and the outer tank after sensing the quantity of the first step, and the laundry after the water supply of the second step is uniformly distributed above the pulsator. The pulsator and the inner tank are rotated to form a third step of performing centrifugal washing, and a fourth step of washing as the pulsator is rotated while the washing water is supplied to the washing level after the centrifugal washing of the third step. do.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a side cross-sectional view showing a general washing machine, Figure 2 is a flow chart illustrating a washing method of a washing machine according to the present invention.

The washing method of the washing machine according to the present invention will be described with reference to FIG. 2, in the first step, the amount of washing is sensed, and the washing level is set according to the amount of washing, and the washing water is supplied (see S1 and S2).

Here, the amount of laundry is sensed while the pulsator 8 is stirred in the state in which the laundry is put in the inner tank 6, and the washing level is determined in proportion to the amount of laundry.

In detail, the motor 10 rotates only the washing shaft 8a in the forward / reverse direction while the washing shaft 8a and the dehydrating shaft 6a are released from each other, so that the pulsator 8 is rotated. By agitating, the amount of power is sensed according to the number of pulses generated by the power of the motor 10 when the power of the motor 10 is turned off.

After the detection of the quantity of water, the motor 10 is stopped, and the water supply valve is opened to wash water and the detergent together through the water supply valve assembly 12 and the detergent box assembly 14. 4) is supplied, the washing water level of the inner tank (6) and the outer tank (4) is sensed by a water level sensor (not shown) attached to one side of the outer tank (4).

In the second step, as the washing water is supplied in the first step, the water supply of the washing water is stopped when the water level is higher than the minimum water level (see S3 and S4).

Of course, the water supply level of the outer tank (4) and the inner tank (6) is detected by the water supply sensor, so that the wash water is supplied only up to a minimum input water level in advance, so that the water supply valve is closed to stop the water supply of the wash water do.

At this time, the minimum water level is set lower than the washing water level determined according to the amount of water, but is set differently according to the amount of laundry so that the laundry is not locked.

In the third step, after the water supply of the wash water is stopped in the second step, the pulsator 8 is stirred, and detergent dissolution and packing are performed (see S5).

Specifically, the motor 10 rotates only the washing shaft 8a in the forward / reverse direction while the washing shaft 8a and the dewatering shaft 6a are released, thereby stirring the pulsator 8. By doing so, as the washing water flows into the inner tank 6 by the pulsator 8, detergent is dissolved in the washing water and laundry is filled in the washing water.

In the fourth step, after the pulsator 8 is stirred in the third step, the pulsator 8 and the inner tank 6 are rotated in one direction, and centrifugal permeation washing is performed during the set time t. )

In detail, the motor 10 rotates the laundry shaft 8a in one of the forward and reverse directions while the laundry shaft 8a and the dehydration shaft 6a are bitten, thereby causing the washing machine 8 and the inner tank to be rotated. 6 is rotated in one direction at the same time, and after the motor 10 is paused, the motor 10 causes the pulsator 8 and the inner tub 6 to rotate in the opposite direction at the same time.

Accordingly, as the pulsator 8 and the inner tub 6 are rotated at the same time, the washing water rises along the inner wall surface of the outer tub 4 by the centrifugal force to hit the tub cover 4a, and then the inner tub 6 Sprayed onto the inner wall surface of the inner tank 6 and attached to the inner wall surface of the inner tank 6.

Of course, when the motor 10 is paused, the laundry attached to the inner wall surface of the inner tank 6 falls to the upper side of the pulsator 8, and thus, the centrifugal washing according to the operation of the motor 10. The laundry is attached to the inner wall surface of the inner tank 6, and then the process of falling to the pulsator 8 side is repeated.

As the inner tank 6 and the pulsator 8 are rotated at the same time in the state in which only the minimum level of washing water is supplied into the inner tank 6 and the outer tank 4 as described above, the washing water is smoothly circulated to dissolve and wash the detergent. Soaking is made quickly, and even if the laundry is introduced to spread above the pulsator 8, the laundry is directed to the inner wall side of the inner tank (6).

In the fifth step, if the wash water is supplied again after the set time (t) of the fourth step, and the water supply level is higher than the washing water level, the water supply of the washing water is stopped, and the washing is performed while the pulsator 8 is rotated. This is done (see S7, S8 and S9).

Here, the water supply valve is opened so that the wash water is supplied into the inner tank 6 and the outer tank 4 through the water supply valve assembly 12 and the detergent box assembly 14, and the water supply level is washed by the water level sensor. The wash water is supplied until the water level is reached, and then the water supply valve is closed to stop the water supply of the wash water.

In addition, the motor 10 rotates only the washing shaft 8a in the forward or reverse direction while the washing shaft 8a and the dehydrating shaft 6a are released, so that only the pulsator 8 is rotated in one direction. The inner tub 6 is rotated in the opposite direction to the pulsator 8 on the principle of action-reaction.

At this time, the laundry that is directed to the inner wall surface side of the inner tank (6) as the pulsator (8) is rotated in one direction can hit the inner tank (6) and the pulsator (8) as well as the effect of rubbing and washing As the water is circulated, the laundry flows smoothly, thereby improving laundry performance.

Washing method of the washing machine according to the present invention constituted as described above centrifugal permeation washing so that the pulsator and the inner tank rotates in one direction at the same time in the state in which the washing water is supplied to the minimum water level lower than the washing level set in accordance with the quantity in the inner tank and outer tank Because it is made so that not only the detergent dissolving and bubbling is made quickly, there is an advantage that can improve the laundry performance by smoothly circulating the laundry.
