Description

Washing control method of drum washing machine

The present invention relates to a washing machine, and more particularly, to a dehydration control method of a drum washing machine.

In general, a washing machine is a machine for washing laundry by performing washing, rinsing, and dehydrating strokes according to a set algorithm. The washing machine is classified into a pulsator type, a stirring type, a drum type, and the like according to a washing method.

At this time, the drum washing machine has been widely used, with the advantage of lowering the damage rate of laundry and the lowest use quantity, compared to other types of washing machines. As shown in FIG. 1, a damper (not shown) inside the main body 1 and the main body 1 is shown. Tub (2) fixed by the (2), laundry is put into the tub (2), the drum (3), the drum (3), which is rotated by receiving the driving force of the motor (10) through the belt (11) and rotating. 3) The thermistor (4) for measuring the temperature of the washing water supplied to the detergent, the detergent container (5) for the input of the detergent, connected to the detergent container (5) to supply the wash water or the washing water mixed with the detergent of the detergent container (5) Water supply pipe (6) for drainage, a drain pipe (7) for discharging the washing water used in the washing stroke to the outside, a pump (8) and a drain hose (9) for forcibly pumping the washing water connected to the end of the drain pipe (7) It is configured to include.

And when looking at the operation of the drum washing machine configured as described above, first, the user opens the door (not shown) attached to the front of the main body 1, put the laundry and then input the washing command, the wash water through the water supply pipe (5) Guided by (6), it is filled in the drum (7).

Subsequently, the water level sensor (not shown) detects that the washing water is filled by the set water level corresponding to the loaded laundry, and outputs the detected value to the controller.

The control unit recognizes the completion of water supply according to the detected value and drives the motor 10 to rotate the drum 3 to proceed with washing.

On the other hand, when the washing is completed, the pump 8 is operated so that the washing water is drained to the outside via the drain pipe 7 and the drain hose 9, and when the draining is completed, the rinsing and dehydrating stroke are continuously performed, and the washing administration is finished. do.

At this time, the drum washing machine is optimally washed when the laundry in the drum 3 falls from the upper side due to the rotation of the drum 3, and the washing proceeds by the friction force that hits the floor.

Drum washing machine according to the prior art proceeds the washing at a specific rpm irrespective of the amount and condition of the laundry, so if the laundry is small, the laundry adheres to the wall, the frictional force due to the falling motion of the laundry is reduced, if there is a lot of laundry rotational movement There is a problem that the washing is not made properly because it does not fall smoothly to the bottom of the drum (3) do not fall.

Accordingly, the present invention has been made in order to solve the above problems, and provides a washing control method of the drum washing machine to prevent the washing performance decrease by washing at a certain rpm irrespective of the amount and condition of the laundry. Has its purpose.

In the laundry control method of a drum washing machine having a control unit, the control unit receives a washing instruction and starts washing to sense a quantity of washing, and the control unit performs washing by varying the motor rotation speed to correspond to the quantity of washing. It is characterized by including the.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the washing control method of the drum washing machine in the present invention.

3 is a flowchart illustrating a washing control method of a drum washing machine according to the present invention.

In the washing control method of the drum washing machine according to the present invention, first, a user opens a door of a drum washing machine, inputs laundry, and inputs a washing instruction through a control panel.

At this time, the controller determines whether a washing instruction is input (S11), and if a washing instruction is input, performs a quantity detection operation (S12).

TABLE 1

Subsequently, the rpm and the motor on / off time corresponding to the quantity detection value are selected from the ROM table shown in Table 1 (S13), and washing is performed (S14).

At this time, the ROM table is set by an experiment and the detailed operation of washing by selecting the rpm and the motor on / off time is as follows.

First, it is determined whether the quantity detected in the quantity detecting operation S12 is 1 kg.

If it is determined that the quantity is 1 kg, the motor on 15 seconds / at a rpm corresponding to the 1 kg and the motor on / off time, i.e., the rotational speed of 48 rpm, among the rpm per quantity stored in the form of a ROM table and the motor on / off time. Washing is performed by applying 3 seconds of motor off.

On the other hand, if the quantity is not 1 kg in the determination step, it is determined whether the quantity is 2 kg, and if it is determined that the quantity is 2 kg, washing is performed by applying motor on 8 seconds / motor off 3 seconds at a rotation speed of 50 rpm. do.

Subsequently, washing is performed by applying the rpm and the motor on / off time correspondingly to the value of the quantity determined by the drum washing machine.

When the washing is completed, the next administration, that is, rinsing or dehydration is performed (S15).

As a result, the present invention detects the amount of laundry and applies a predetermined rpm value and a value corresponding to the amount during the motor on / off time to the washing administration.

The washing control method of the drum washing machine according to the present invention has the effect of maximizing the washing performance by setting the rpm and the motor on / off time to satisfy the optimal washing conditions according to the amount of the laundry and proceeding with the application. have.
