Description

Washing method of washing machine

The present invention relates to a washing administration method of a washing machine, and more particularly, to a washing administration method of a washing machine providing an optimal washing algorithm since the driving operation is performed by setting an optimal washing driving pattern according to the conditions under which the washing operation is performed.

In general, a washing machine is a machine for quickly and cleanly washing contaminants attached to clothes and bedding by using emulsification of detergents, friction of washing water due to rotational movements, and impact with laundry. 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 washing water flow, the detergent and the total washing time according to the quantity, and then reverses rotation of the pulsator with the whole washing time. Vortex the water through the laundry to perform the laundry administration to separate the stains on the laundry by friction with the laundry.

Next, when the washing administration is completed, the turbid wash water is discharged and the new washing water is supplied from the washing tank to rinse for a predetermined 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.

The washing machine has a basic structure including a washing tank into which laundry is put in the outer case, a driving unit for rotating the washing tank, and a valve for supplying water when the entire washing process is performed. In the same washing machine, after washing, rinsing, etc. of the laundry, dehydration is performed to improve the efficiency of washing and rinsing, and finally, in the operation of the overall washing machine, a complete dehydration is performed. If the washing water flow, detergent and total washing time are set according to the quantity during the administration, the washing water is not wetted in the washing water because the washing machine is driven immediately after the washing water is supplied to the set washing water level. In this case, the laundry floats, rubbing the laundry with the laundry or the tub. It is difficult to wash by, and when the detergent is not completely dissolved, there is a problem that not only the washing efficiency due to the emulsification of the detergent is lower than the input amount of the detergent, but the detergent may directly contact the laundry and damage the laundry.

The present invention has been made in order to solve the above problems of the prior art, washing machine that can improve the washing performance by performing a full-fledged washing after fully dissolving the detergent in the washing water and washing the laundry fully in the washing administration. To provide a laundry administration method.

Step 3; A fourth step of stopping the washing tank and the pulsator and supplying the washing water to the washing set water level when the third step is completed; In the fourth step, when the wash water is supplied to the washing water level, the washing machine comprises a fifth step of performing washing by alternately driving the pulsator to the left and right for a predetermined time.

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

1a and 1b, 1c, 1d is a view showing a washing mode according to the present invention, Figure 2 is a graph showing the water level according to the washing mode of the washing machine according to the present invention.

In general, the washing machine has a washing tank 12 rotatably installed inside the water tank 11 in the main body 10, and a pulsator 13 that rotates during washing is installed in the lower center of the washing tank 12.

In addition, the washing tank 12 and the pulsator 13 penetrate through the dehydration shaft 15 and the washing shaft 16 of the clutch 14 installed in the center of the bottom surface of the water storage tank 11, respectively, and the water storage tank ( A motor pulley 18 and a clutch pulley 19 are installed in the motor 17 and the clutch 14 which are mounted on one side of the bottom of the 11 and driven by a control signal of a microcomputer (not shown), respectively. The V-belt 20 is wound between 18 and the clutch pulley 19 so as to transmit power.

In the washing operation control of the washing machine as described above, when the quantity of laundry or the like put into the washing tank 12 is determined, the washing water flow and the detergent and the total washing time are set according to the quantity, and then the pulsator is accompanied by the total washing time. The washing stroke is performed by vortexing water through the reverse rotation of (13) to separate the stains on the laundry by friction with the laundry.

Next, when the washing stroke is completed, the turbid washing water in the washing tank 12 is discharged, and new water is supplied to the washing tank 12 to perform a rinsing cycle for rinsing for a predetermined number of times. When the rinsing stroke is completed, the water in the washing tank 12 is discharged, and the motor is rotated at a high speed to remove the laundry by centrifugal separation.

FIG. 1A illustrates a first mode for determining a washing set water level according to the present invention. The laundry to be washed is put into the washing tank 12 and the washing tank and the pulsator 12 and 13 are in a state in which no washing water is available. And when rotating the laundry integrally, by measuring the time it takes for the motor to rotate one by one to sense the amount of laundry put into the washing tank (12). At this time, when the amount of the laundry is large, the time required for one revolution becomes long.

Figure 1b shows a second mode of performing the core in accordance with the present invention, while the washing tank and the pulsator 12 and 13 integrally with the laundry while slowly rotating at the same direction / the same rotational speed of the water supply valve 21 The water is supplied to drive the washing water so as to quickly and uniformly penetrate the laundry. At this time, the rotational speed of the wash water and the pulsator 12 and 13 is rotated at a low speed so that the centrifugal force does not occur in the laundry, and can be reversed side to side, but there is no wash water circulated through the pumping channel (not shown).

Figure 1c shows a third mode for performing a detergent dissolution process according to the present invention, the washing tank and the pulsator (12 and 13) by inverting the left and right integrally driving the inner wall of the washing tank and the pulsator 13, the protrusions and the laundry Washing by friction and the laundry between the washing tank and the laundry by the rotational flow of the pulsator (12 and 13) to remove the dirt of the clothing. At this time, since the third mode has a faster reversal speed than the second mode, the washing water is separated from the washing tank and the pulsator 12 and 13, and the frictional force of the pulsator 13 is difficult to transfer. The frictional force is transmitted to the laundry so that uniform washing is possible.

FIG. 1D illustrates a fourth mode according to the present invention, wherein the pulsator 13 is inverted from side to side to drive the pulsator 13 to the projection of the upper end of the pulsator 13 and the vortex flow in which the pulsator 13 generates friction. Due to the friction between the laundry, the dirt of the laundry is removed.

The washing administration method of the washing machine according to the present invention will be described with reference to the graphs and flowcharts shown in FIGS. 2 and 3 as follows.

First, the first step is to initialize the washing machine by applying power to the washing machine and to put the laundry in the washing tub 12 of the washing machine, and then input the washing conditions desired by the user through the key input unit (not shown) and turn on the operation button Step 1 is performed (see S1).

Next, using the first mode in which the washing tank, the pulsator (12 and 13) and the laundry is rotated in the absence of the wash water, the amount of time is detected by measuring the time required for the motor to rotate one by one, and according to the detection result A second process of determining the washing set water level H2 is performed. In this case, the quantity of gas is sensed by driving the pulsator 13 inverted left and right, and when the amount of the laundry is large, the time required for one rotation of the motor becomes long (see S2).

In the second step, the washing tank and the pulsator 12 and 13 are driven by driving the water supply valve 21 using the second mode to supply the washing water to the detergent dissolution water level H1 lower than the washing set water level H2. Rotates at low speed in the same direction / same rotational speed as the laundry. At this time, when the washing water is supplied, the detergent is set in the washing tank 12 according to the quantity of water in the second step S2 of the first step. The washing tank and the pulsator 12 and 13 are rotated slowly so that the laundry is not compressed to the inner wall of the washing tank 12 by centrifugal force, so that the washing water is quickly and uniformly washed without passing through the laundry by the centrifugal force. It is possible to infiltrate by infiltrating it quickly (see S3).

In the third step, when the second step S3 is completed using the third mode, that is, when the washing water is supplied to the detergent dissolution water level H1, the driving of the water supply valve 21 is stopped to stop the water supply. At the same time, the washing tank 12 and the pulsator 13 are driven to the left and right inverted together in the same direction and at the same rotational speed for a predetermined detergent dissolution time T1. At this time, washing by the washing tank 12 and the pulsator 13 Since the vortex is formed in the water, the detergent is dissolved in the wash water, so that the detergent can be completely dissolved quickly. As the washing tank 12 is rotated together, the rotational force of the pulsator 13 is reduced in the washing tank 12. Even if it is not sufficiently delivered to the upper portion, the vortex is sufficiently formed in the upper portion of the washing tank 12 so that the detergent can be evenly dissolved. (See S4, S5, and S6.)

The fourth step determines whether the predetermined detergent dissolution time T1 has elapsed, and if the determination result of the seventh step is negative, the sixth step S6 is continued until the detergent dissolution time T1 has elapsed. When the time T1 elapses, the washing tank and the pulsator 12 and 13 are stopped, and the water supply valve 21 is driven to wash the washing water to the washing set water level H2 determined in the second step S2 of the first step. On the other hand, in the fourth step, since the washing water is supplied to the detergent-dissolving water level H1, the washing tank 12 or the pulsator 13 is supplied while the washing water is supplied to the washing setting water level H2. The driving process may be further included to improve cleaning power.

In the fifth step, it is determined whether the washing water reaches the washing set water level H2. If the determination result is negative, the water is supplied until the washing water level reaches the washing set water level H2. The water supply is stopped by determining that the water is supplied to the washing set water level H2 (see S9 and S10).

Then, the water supply is interrupted and the pulsator 13 is left and right reversed and alternately driven during the preset washing setting time T2 to emulsify the vortex and the detergent formed in the wash water, and the friction between the washing tank 12 and the laundry. After washing the laundry by the main washing process as described above, it is determined whether or not the predetermined washing preset time T2 has elapsed. If the result of the determination is affirmative, it is determined that the washing operation is completed and the driving of the pulsator 13 is stopped. End the laundry administration (see S11, S12 and S13).

When the washing cycle is finished, the user performs a rinsing stroke and a dehydration stroke after a set or preset series.

In the washing administration method of the washing machine according to the present invention configured as described above, the washing set water level is set according to the quantity of water, and the washing tank and the pulsator are integrally formed at the same direction and at the same speed as the washing water is supplied to the detergent dissolving level after detecting the amount of water. When the washing is carried out by the spinning, and the washing water is supplied to the detergent dissolution level, the pulsator is stirred and driven to completely dissolve the detergent, and thus the washing performance is improved, thereby not only improving washing performance but also minimizing damage to the laundry. In particular, when the detergent is dissolved, since the washing tank is rotated integrally with the pulsator at the same direction and at the same rotational speed, sufficient vortex is formed to the upper part of the washing tank, so that the degree of dissolution of the detergent can be improved. There is an advantage to that.
