Description

Rinsing control method of washing machine

The present invention relates to a rinsing control method of a washing machine, and more particularly, when a large rinsed laundry such as a blanket or a blanket is washed after rinsing after a second rinsing stroke, the water is rinsed during the rinsing stroke. The present invention relates to a rinsing control method of a washing machine capable of overflowing to discharge dust, lint, and the like out of a tank.

The washing machine transmits the rotational force of the motor to a rotary blade (also called a pearl shader) to rotate the rotary blades to form a water flow, and the water flow formed by the rotation of the rotary blades impacts the laundry so as to wash the laundry.

Referring to Figure 1 describes the control operation of the blanket / blanket course of the conventional washing machine as follows.

First, the user sets the futon / blanket course through the function setting unit to wash the blanket or blanket (S1). The function setting unit inputs a futon / blanket signal to the control unit according to the contents set by the user.

The control unit drives the washing machine according to the signal output from the function setting unit. First, the water supply valve driving unit is driven to open the water supply valve to supply water to the water tank of the washing machine (S2).

When water supply starts and water starts to fill the tank, the controller detects the water level in the tank. The controller detects the water level using the water level detector. The controller detects the water level of the current water supply and then compares the detected water level of the water tank with the set water level to determine the water supply completion.

If it is determined that the water supply is completed, the control unit ends the water supply and drives the washing machine driving unit to operate the washing machine and performs the washing administration (S3).

At the end of the washing administration time, the control unit completes the washing administration and controls the drain valve driver to open the drain valve to drain water (S4).

While draining, the controller senses the level of water drained through the water level detector to determine whether draining is completed. If the drainage is not completed, the controller continuously drives the drain valve driver to keep the drain valve open. If it is determined that drainage is completed, the control unit performs dehydration and performs a rinsing stroke.

The control unit is to supply the water to rinse, by controlling the water supply valve driver to open the water supply valve to supply water (S6). At this time, too, the control unit determines the water level of the tank. If it is determined that the water supply is completed by judging the level of the water tank, the controller controls the water supply valve driver to lock the water supply valve and complete the water supply.

After the water supply is completed, the control unit performs a rinsing stroke (S7).

When the rinsing stroke is completed, the control unit controls the drain valve driver to open the drain valve to drain the water (S8).

After the drain S8, the controller determines whether the set number of rinses is completed (S9).

If it is determined that the number of rinses set in the determination (S9) is not completed, the control unit supplies water for rinsing (S6). After the water supply is completed, the control unit performs a rinsing stroke (S7).

However, if it is determined that the number of rinses set in the determination (S9) is completed, the control unit performs dehydration administration (S13). When the dehydration stroke is performed, the controller determines whether the dehydration time set in the setting S1 has ended. If it is determined that the dehydration time is finished, the controller completes the dehydration administration and ends.

However, after each rinsing cycle, drain the water as it is. Therefore, in the case of large laundry such as blankets or blankets, which almost occupy the washing tank, lint or dust is stuck to the laundry without being discharged during drainage. Therefore, after washing and drying, there was an inconvenience of brushing dust or lint on the laundry with a brush.

The present invention has been made to solve the above problems, its purpose is to rinse administration of large laundry such as duvets or blankets, overflow rinsing overflowing the water supplied during the rinsing time in the rinsing from the second By doing so, it is to provide a washing machine to provide a rinsing control method of the washing machine to discharge dust or lint, etc. to the outside of the tank and do not need to clean after drying.

It is provided.

In addition, the drain valve driving unit 71 is driven by the control of the control unit 40 at the time of drainage, and the drain valve 72 is opened and closed in accordance with the drive of the drain valve driver 71.

Hereinafter, the rinsing control method of the blanket / blanket course of the washing machine according to the present invention.

First, the user sets the blanket / blanket course through the function setting unit 11 to wash the blanket or blanket (S110). At this time, if the user selects a futon / blanket course, the water level, rinsing time, etc. are set accordingly. When the futon / blanket course is set, the control unit 40 controls the water supply valve driver 61 to open the water supply valve 62 to start water supply (S120).

When the water supply valve 62 is opened and water supply is started, the control unit 40 detects the water level of the water supplied through the water level detection unit 20. The controller 40 detects the water level of the current water supply and then determines the water supply completion by comparing the detected water level with the set water level (S130).

If it is determined in the determination (S130) that the water level detected through the water level detection unit 20 reaches the water level set in the setting (S110), it is determined that the water supply is completed, and the controller 40 controls the water supply valve driver 61 to supply water. Close the valve 62 and stop the water supply (S140). However, if it is determined in the determination (S130) that the water level detected through the water level detection unit 20 did not reach the water level set in the setting (S110), the control unit 40 determines that the water level of the water supply does not reach the setting water level, and is presently operated. Continue to open the water supply valve to the water supply (S130).

When water is completed and the water is filled in the tank, the controller 40 controls the washing machine driving unit 50 to drive the motor. When the motor is driven, the rotational force of the motor is transmitted to the clutch mechanism through the belt, whereby the pulsator is operated to perform the washing stroke (S150).

When the washing administration is carried out (S150), the control unit 40 checks the time when the washing administration is performed through the timer 30, and when the set washing administration time is completed, the control unit 40 controls the washing machine driving unit 50 to control the motor. Stop the washing operation.

When the washing operation is finished, the control unit 40 drives the drain valve driver 71 to open the drain valve 72 to drain the water in the tank (S160). During the drainage, the water level detection unit 20 detects the water level and outputs the signal to the control unit 40. The control unit 40 receives the signal output from the water level detection unit 20 to detect the water level and the drainage is completed. Determine if

After the drainage, the control unit 40 controls the washing machine driving unit 50 to perform a dehydration operation (S170).

After the dehydration is completed, the control unit 40 performs a rinsing stroke. First, the control unit 40 determines whether it is the first rinsing stroke (S180).

If it is determined in the determination (S180) that the first rinsing stroke, the control unit 40 performs a general rinsing stroke. Here, the general rinsing stroke is as follows. In general, the rinsing operation is to supply water first, and when the water level reaches a predetermined level, the water supply is stopped and then rinsed.

If it is determined in the determination (S180) that the first rinsing stroke, first watering (S190). In order to supply water, the controller 40 controls the water supply valve driver 61 to open the water supply valve 62 to supply water.

When the water supply S190 starts, the water level detecting unit 20 outputs a signal corresponding to the water level of the water tank to the controller 40. The controller 40 receives a signal output from the water level detector 20 as an input and detects the water level.

The control unit 40 detects the water level of the water to be supplied, and then determines whether the detected water level reaches the water level set in the setting (S110) (S200).

If it is determined in the determination (S200) that the water level detected through the water level detection unit 20 reaches the water level set in the setting (S110), it is determined that the water supply is completed, and the controller 40 controls the water supply valve driver 61 to supply water. Closing the valve 62 stops the water supply and completes the water supply (S210).

However, if it is determined in the determination (S200) that the water level detected through the water level detection unit 20 does not reach the water level set in the setting (S110), the control unit 40 determines that the water level of the water supplied does not reach the setting water level. Watering (S190).

When water is completed and the water is filled in the tank, the controller 40 drives the washing machine driving unit 50 to perform a rinsing stroke (S220). When the rinsing stroke is performed, the controller 40 integrates the time through the timer 30. The controller 40 ends the rinsing and rinsing when the accumulated time reaches the set rinsing time through the timer 30.

When the rinsing stroke is completed, the control unit 40 controls the drain valve driving unit 71 to open the drain valve 72 and drains the water through the drain pipe (S240).

After the drainage, the control unit 40 determines whether the number of rinses set in the setting (S110) is completed (S250). In other words, it is determined whether the rinsing stroke is advanced by the number of rinses set in setting S110.

If it is determined that the rinsing stroke has not progressed by the number of rinses set in the determination S250, the controller 40 repeats the rinsing stroke. In order to repeat the rinsing cycle, the controller 40 first determines whether it is the first rinse (S180).

If it is determined in the determination (S180) that it is not the first rinsing, the control unit 40 performs an overflow rinsing to discharge dust, lint and dust which are not easily discharged during drainage.

The control unit 40 controls the water supply valve driver 61 to open the overflow rinse to open the water supply valve 62 and start water supply (S181). When the water supply starts, the control unit 40 detects the water level through the water level detection unit 20 and determines whether the detected water level reaches the set water level (S182).

If it is determined in the determination (S182) that the detected water level does not reach the set water level, the controller 40 continuously opens the water supply valve 62 and controls the water supply valve driver 61 so that water supply is continued (S181).

However, if it is determined in the determination (S182) that the detected water level reaches the set water level, the controller 40 controls the washing machine driving unit 50 to rinse (S183). At this time, the control unit 40 maintains the water supply valve 62 open by controlling the water supply valve driver 61 so that the water supply can be continued for the overflow rinsing.

Since the water supply valve 62 is kept open during the rinsing, the water to be supplied is passed over the washing tank and the water beyond the washing tank is drained to the drain pipe through the main water pipe. Thus, dust, lint, and dust floating on the water are discharged to the outside.

While the rinsing is performed, the controller 40 adds time through the timer 30 to determine the rinsing completion (S184). The controller 40 controls the washing machine driver 50 to complete the rinsing when the accumulated time reaches the set rinsing time through the timer. The control unit 40 controls the water supply valve driver 61 to close the water supply valve 62 so that water supply is stopped.

Then, the control unit 40 controls the drain valve driver 71 to open the drain valve 72 to perform drainage (S240).

After the drainage, the control unit 40 determines whether the number of rinses set in the setting (S110) is completed (S250). If it is determined in the determination S250 that the rinsing frequency set in the setting S110 has not yet been completed, the above-described rinsing cycle according to the rinsing frequency is repeated.

However, if it is determined that the number of rinses set in the determination (S250) is finished, the control unit 40 performs dehydration stroke (S260).

When the dehydration administration is performed, the controller 40 determines whether the dehydration time set in the setting (S110) is terminated through the timer 30, and when it is determined that the dehydration time is finished, the control unit 40 completes the dehydration administration and ends.

According to the rinsing control method of the washing machine according to the present invention, when rinsing in the futon / blanket course of the washing machine, in the second rinse, the overflow rinsing to overflow the water that is continuously supplied during the rinsing time drainage By discharging dust or lint, etc., which are not easily discharged to the outside, it is not necessary to clean laundry after drying, thereby providing convenience and reliability to the user.
