Description

Method for Controlling Washing Course of Washing Machine

The present invention relates to a washing machine, and more particularly, to a washing stroke control method of a washing machine for performing the washing stroke effectively.

In general, a washing machine is a device that removes contaminants from contaminated laundry through washing, rinsing, and dehydration according to a predetermined algorithm. The washing machine or drum uses a horizontal washing of a pulsator, an outer tub, or a washing tub. It can be divided into drum washing machine using vertical rotation.

Such a washing machine has been developed in various washing courses, functions, etc. in order to respond to various needs of the user and is applied to actual products.

The washing machine includes a key input unit for a user to input various washing-related operation commands, a motor for directly or indirectly rotating an inner tank or an outer tank, a pulsator rotating directly or indirectly by the motor, A pumping channel formed between the outer tank and the inner tank, other loads such as a water supply valve and a drain valve, and a microcomputer for controlling the motor and the load to perform a washing operation corresponding to an operation command input through the key input unit. It is composed.

At this time, the outer tank and the inner tank forms a washing tank and rotates directly or indirectly by the motor with the pulsator. In addition, a pumping channel may be formed to circulate and pump the wash water between the outer tub and the inner tub during the washing stroke.

1 is a view showing a washing stroke control method of a washing machine configured as described above, when the washing stroke control method of a washing machine according to the prior art will be described.

First, a user inputs an administrative command through the key input unit, and the microcomputer controls the motor and various loads so as to perform washing, rinsing, and dehydration strokes according to the input administrative command.

At this time. Referring to the control method of the 'laundry administration' according to the prior art as follows.

When the washing stroke is started under the control of the microcomputer, the washing stroke is controlled by the first mode of rotating the washing tank for a first preset time at a preset first rotation speed V1 and a first rotation angle A1. Control (S10).

Subsequently, when the first set time elapses, the washing stroke is controlled by a second mode in which the washing tank is rotated for a second preset time at the preset second rotation speed V2 and the second rotation angle A2. (S11).

Then, when the second set time elapses, the washing operation is controlled by a third mode in which the washing tank is rotated for a third set time set at the preset third rotation speed V3 and the third rotation angle A3. (S12).

When the third set time elapses, the washing operation is repeatedly controlled by the first mode for a preset first 'set time (S13). When the first set time has elapsed, the second during the second set time. The washing operation is repeatedly controlled by the mode (S14).

In this case, the first, first ', second, second', the third set time is the first set time is the longest, and then the first 'set time, the second' set time, the second set time, The third set time is shortest in the order of the third set time.

2, in the first, second and third modes, the first (V1), the second (V2), and the third (V3) rotational speed are the third rotational speed. (V3)> the first rotational speed (V1)> the second rotational speed (V2) is satisfied, the first (A1), the second (A2), the third (A3) rotation angle of the third The conditions of the rotation angle A3> the first rotation angle A1> the second rotation angle A2 are satisfied.

Accordingly, in the first, second and third modes, as shown in FIG. 2, the washing tank is rotated by rotating the washing tank at a constant rotation speed and rotation angle.

As described above, the washing administration control method of the washing machine according to the prior art, since each mode for controlling the washing administration controls the washing stroke at a constant speed and at an angle for a predetermined time, the washing cloth is not smoothly replaced by the upper and lower sides of the washing cloth. There was a problem of degrading performance.

The present invention has been made to solve the above problems, an object of the present invention is to provide a washing administration control method of the washing machine to improve the washing performance.

Figure 2 is a graph showing the conditions of each control mode for controlling the washing administration according to the prior art

Figure 3 is a graph showing the conditions of each control mode for controlling the washing administration according to the present invention

Washing stroke control method of the washing machine according to the present invention for achieving the above object is the first pattern and the first 'rotating speed and the first' A first mode in which the washing tub is rotated for a first set time in a second pattern controlled at a rotation angle, a second mode in which the washing tub is rotated for a second set time at a second rotation speed and a second rotation angle; And controlling the washing operation by the third mode rotating at the third rotational speed and the third rotational angle for a third set time.

Hereinafter, a washing stroke control method of a washing machine according to the present invention with reference to the accompanying drawings.

Since the configuration of the washing machine according to the present invention is the same as described above, a description thereof will be omitted.

First, a user inputs an administrative command through the key input unit, and the microcomputer controls the motor and various loads so as to perform washing, rinsing, and dehydration strokes according to the input administrative command.

At this time. Referring to the control method of the 'laundry administration' according to the present invention.

When the washing stroke is started, the washing stroke is controlled by the first mode in which the washing tub is rotated for the first preset time (S10).

In the present invention, the first mode according to the present invention is the first 'rotation speed (in the first conventional mode described above) to rotate the washing tank at the first rotational speed V1 and the first rotational angle A1. V1 ') and the first rotation angle A1' combine the patterns for rotating the washing tank at a predetermined ratio to control the washing operation during the first set time.

In other words, the washing stroke control during the first set time may include the first rotation speed V1 'and the first' in a first pattern having the first rotation speed V1 and the first rotation angle A1. Control is performed by the first mode in which the second pattern having the rotation angle A1 'is combined at a predetermined ratio. Since the rotation angle A1 ′ of the second pattern is relatively larger than the rotation angle A1 of the first pattern, the washing tank is rotated greatly and a large amount of rotation is applied to the washing cloth.

The washing administration control by the second and third modes is the same as the conventional washing administration control method described above.

Subsequently, when the first set time elapses, the washing operation is controlled by a second mode in which the washing tank is rotated for a second preset time at the preset second rotation speed V2 and the second rotation angle A2. (S11).

Then, when the second set time elapses, the washing operation is controlled by a third mode in which the washing tank is rotated for a third set time set at the preset third rotation speed V3 and the third rotation angle A3. (S12).

After the third set time has elapsed, the washing operation is repeatedly controlled in the first mode for the first set time (S13). If the first set time has elapsed, the washing process is performed during the second set time. The washing operation is repeatedly controlled in two modes (S14).

In this case, the first, first ', second, second', the third set time is the same as described above.

In the present invention, as shown in Fig. 3, in the first, second and third modes, the first (V1), the first '(V1'), the second (V2), the third ( V3) The rotational speed satisfies the condition of the third rotational speed V3> first rotational speed V1> second rotational speed V2> first 'rotational speed V1', and each of the first ( A1), the first (A1 '), the second (A2), the third (A3) rotation angle is the third rotation angle (A3)> the first rotation angle (A1')> the first rotation angle (A1) > Satisfies the condition of the second rotation angle A2.

Accordingly, the second and third modes perform the washing stroke by rotating the washing tank at a constant rotation speed and rotation angle, respectively, while the first mode performs the washing stroke by appropriately combining different rotation speeds and rotation angles. As a result, a second pattern having a large rotation amount is applied to the laundry cloth every predetermined cycle to perform washing with even washing.

The washing stroke control method of the washing machine according to the present invention described above has the effect of improving the washing performance by applying the washing degree evenly to the washing cloth by controlling the washing stroke at different rotation speeds and rotation angles for a predetermined time. .

Those skilled in the art will appreciate that various changes and modifications can be made without departing from the spirit of the present invention.

Therefore, the technical scope of the present invention should not be limited to the contents described in the embodiments, but should be defined by the claims.
