Description

Washing machine control method {Washer controlling method}

The present invention relates to a control method of a washing machine, and more particularly, to a control method of a washing machine that can implement permeation washing using a Vesu motor and a drain valve operated in two stages.

In general, a washing machine is a machine that removes stains on clothing. When it is put on clothing, it is removed from the fibers by the chemical action of detergent when put in the washing liquid, but it takes a long time by the action of detergent alone. Applying a mechanical action increases the speed at which the time is missing, it is the role of the washing machine to provide such a mechanical action.

In the permeation washing process, the washing tank is rotated at a high speed as in the dehydration mode to make the 'V' shaped water inside the washing tank to proceed with washing. The water moved to the outside of the washing tank by centrifugal force penetrates the laundry and washes. Next, after passing through the washing tank is moved to the storage tank, the wall of the storage tank rises upwards to repeat the flow of the fluid flowing into the washing tank again.

In the conventional washing machine, as shown in FIGS. 1 and 3, a water storage tank 2 is installed inside the case 1, and laundry and washing water are supplied into the water storage tank 2 to drive the driving force of the motor 10. Washing tank (3) in which washing and rinsing is performed by the washing blade (4) which is transmitted and rotated.

In the washing and rinsing mode, in the state in which the drain valve 33 is closed while the drain motor 30 is turned off, and the washing water is not drained, a connection link for transferring the operation of the drain motor 30 to the drain valve 33 ( 31, the brake lever 32 is interlocked so that the brake band 15 is in a position to fix the dehydration shaft 14 according to the position of the link link 32, and the front end of the clutch lever 12 is clutch By pulling the end of the spring 16, the clutch spring 16 is larger than its original diameter, that is, the clutch 20 is released, so that the washing shaft 5 connected to the washing blade 4 is connected to the washing tank 3. It is in a state of being free from the deshrink 14 connected with. Therefore, the rotational force of the motor 10 is transmitted to the washing shaft 5 through the pulleys 7 and 9 and the belt 8 and the planetary gear 6, and the washing blade 4 according to the rotation direction of the motor 10. By rotating the washing and rinsing of the laundry is made.

In the dehydration mode, the drain motor 30 is operated to retract the connecting link 31 to the rear, and the drain valve 33 is opened to be in a state in which the wash water can be drained. Retraction moves the brake lever 32 so that the brake band 15 holding the dehydration shaft 14 is released from the dehydration shaft 14, and the coupling screw 16 moves while the brake band 15 is moved backward. The clutch lever 12 to which the coupling screw 16 is fastened is released to restore the clutch spring 16 to its original state, and the washing shaft 5 and the dewatering shaft 14 are engaged to rotate together. Therefore, the rotational force of the motor 10 is transmitted to both the washing shaft 5 and the dehydration shaft 14 to be dehydrated.

In addition, there is also a washing machine in which the drain motor and the drain valve are operated in two stages according to their respective purposes.

Reference numeral 11 denotes a spring case, and 13 denotes a spring block.

However, the conventional washing machine has to rotate at a high speed in a state in which the washing shaft 5 and the dehydration shaft 14 are engaged with each other when the washing machine 3 is to be rotated at a high speed in the washing and rinsing mode. When the dehydration shaft 14 is engaged with the dehydration mode (5), the drain valve 33 interlocked with the clutch 20 is opened in the same manner as the dehydration mode, so that the wash water flows out.

The present invention has been made to solve the above problems of the prior art, the object of the present invention is to provide a control method of a washing machine that can implement permeation washing using a drain valve and a drain motor operated in two stages.

Washing tank 52 which is supplied with water and the washing proceeds, washing wing 54 to form a water flow so that washing is carried out inside the lower portion of the washing tank 52, and washing shaft 55 connected to the washing wing 54 And a planetary gear 56 connected to the washing shaft 55 to increase and decrease the rotation speed of the washing shaft 55, and pulleys 57, 59 and a belt 58 on the washing shaft 55. A driving motor 60 for transmitting a driving force, a dehydration shaft 61 connected to the washing tank 52, and transmitting a driving force to the washing tank 52, the washing shaft 55 and the dewatering shaft 61. The clutch 70 is connected to each other to control the interconnection, and is provided on the outside of the dehydration shaft 61 to brake the drive of the dehydration shaft 61 A brake band 62, a drain valve 90 that opens and closes to drain the wash water in the reservoir 53, a drain motor 80 for controlling the operation of the drain valve 90, and the drain motor 80 The connection link 81 is installed between the drain valve 90 and the drain motor 80 and the connection link 81 so that the operation of the brake band 62 and the clutch 70 is interlocked with the operation. It is composed of a brake lever 63 for transmitting to the brake band 62.

Here, the clutch 70 is connected to the clutch case 72 and the clutch case 72 so that the clutch 70 is restrained or released according to a change in diameter, and the washing shaft 55 and the dewatering shaft 61 are connected. Change in the diameter of the clutch spring (71) by being installed to interlock with the clutch spring (71) and the coupling screw (64) connected with the brake lever (63), and by disengaging the distal end of the clutch case (72). It consists of a clutch lever 73 to bring.

In particular, as shown in FIG. 6, the drain valve 90 has a first rod 91 connected to the connection link 81 and a step 91a formed therein, and a step 91a of the first rod 91. Step (92a) is formed so as to be caught, and the second rod 92 is connected to the front end of the drain valve (90). That is, when the connection link 81 is pulled by the drainage motor 80, the drainage until the step 92a of the second rod 92 is caught by the step 91a of the first rod 91. The drainage motor 80 is operated again while the valve 90 is closed and the step 92a of the second rod 92 is caught by the step 91a of the first rod 91. Thus, when the connection link 81 is pulled, the drain valve 90 is opened. Of course, the drain motor 80 is also operated in two stages so that the drain valve 90 can operate in two stages.

Referring to the operation of the washing machine according to the present invention configured as described above in detail.

First, in the stirring washing mode, as shown in FIGS. 6 and 7, since the drain motor 80 is maintained in an off state, the step between the first rod 91 and the second rod 92 is maintained. 91a and 92a are not in contact with each other, and the drain valve 90 is closed. Since the brake band 62 is held such that the dehydration shaft 61 cannot be rotated, and the front end of the clutch lever 73 is pulling the clutch spring 71, the diameter of the clutch spring 71 is increased. The clutch 70 is in a state of being larger than the original diameter. That is, when the driving motor 60 is operated in the state in which the washing shaft 55 and the dehydration shaft 61 are released and the drain valve 90 is closed as described above, the driving force of the driving motor 60 is determined. The washing blade 54 is transferred to the washing blade 54 via a pulley 59, a belt 58, a pulley 57, a planetary gear 56, and a washing shaft 55, so that the washing blade 54 is driven by the driving motor 60. Rotate left and right according to the driving of). In addition, since the washing tank 52 maintains a fixed state because the dehydration shaft 61 is restrained by the brake band 62, stirring washing and stirring rinsing are performed.

And, in the case of the transmission washing mode, as shown in Figure 8, the drainage motor 80 is operated by one stage, the connection link 81 is pulled a certain distance, accordingly the second rod 92 is The step 92a is pulled to a position that is caught by the step 91a of the first rod 91. Therefore, the drain valve 90 is maintained in a closed state, and since the connection link 81 is pulled a predetermined distance, the brake lever 63 is also moved so that the brake band 62 is dehydrated. 61, the dehydration shaft 61 is free, and the front end of the clutch lever 73 interlocked with the brake lever 63 is placed in a position where the clutch spring 71 returns to its original state. The coupling shaft 55 and the dehydration shaft 61 is coupled. In this state, when the driving motor 60 rotates at a high speed, the rotational power of the driving motor 60 is transmitted to the washing blade 54 and the washing tank 52, and the washing blade 54 and the washing tank 52. Since the high-speed rotation in the same direction to proceed with permeation washing and permeation rinsing.

In addition, in the dehydration mode, as shown in Figure 9, the drainage motor 80 is operated in two stages to pull the connection link 81 farther than when the first stage operation, the second rod 92 The second rod 92 is pulled in a state where the step 92a of the rod is caught on the step 91a of the first rod 91, so that the first rod 91 and the second rod 92 are Pulled together, the drain valve 90 is opened. In addition, the brake lever 63 is also pulled out, but the brake band 62 maintains the restrained state of the dehydration shaft 61 and the clutch 70 also remains restrained. That is, there is a difference in that the drain valve 90 is opened from the permeation washing mode. In this state, the drive motor 60 is rotated at a high speed, so that dehydration proceeds.

Of course, the stirring washing mode, the permeation washing mode, and the dehydration mode may be sequentially performed, and a combination thereof may be controlled to be operated according to a user's input.

As described above, the control method of the washing machine according to the present invention can improve the cleaning power by implementing the permeation washing which cannot be executed conventionally by simply installing the drain valve 90 and the drain motor 80 operating in two stages. Provide effect.
