Description

How to rinse the drum washing machine

The present invention relates to a washing machine, and more particularly, to a rinsing 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 up to a predetermined level corresponding to the laundry which has been introduced 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 conventional drum washing machine supplies water when the washing operation is finished and rotates the motor forward and reverse for a predetermined time so that the detergent residue and foam contained in the laundry in the drum 3 are diluted by the water supplied in the washing water and then drained. Rinsing was performed by the method.

The rinsing method of the drum washing machine according to the prior art has a problem in that it does not completely separate the detergent residues and bubbles contained in the laundry, thereby lowering the rinsing performance.

Accordingly, an object of the present invention is to provide a rinsing method of a drum washing machine, which is designed to solve the above-mentioned problems and improves rinsing performance.

The present invention relates to a method of rinsing a drum washing machine having a shower water supply unit, the method comprising: performing a washing according to an input washing instruction, rotating the drum at a constant speed when the washing operation is finished, and showering water while the drum is rotating And performing a shower water supply and drainage through the unit, and performing a rinsing stroke after completion of the shower water supply and drainage.

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

2 is a flowchart illustrating a rinsing method of a drum washing machine according to the present invention, and FIG. 3 is a view illustrating an initial rinsing water supply state of the drum washing machine according to the present invention.

In the rinsing method of the drum washing machine according to the present invention, as shown in FIG. 2, a user first opens a door 21 of the drum washing machine and inputs laundry, and then inputs a washing instruction through the control panel. Therefore, the control unit applies a control signal to each unit to correspond to the washing instruction. Subsequently, the washing motor, various valves, etc. are driven by receiving the control signal of the controller to perform washing.

Then, the controller determines whether the washing stroke is finished (S11), and when the washing stroke is finished, before the rinsing stroke is performed, the motor 10 is driven to rotate the drum 3 at a speed of about 100 rpm for a predetermined time. (S12).

At this time, when the drum 3 is rotated at the speed of 100 rpm, the laundry in the drum 3 is rotated together with the drum 3 without falling off the inner wall of the drum 3 by centrifugal force.

Subsequently, shower water supply and drainage are performed simultaneously (S13).

At this time, as shown in Figure 3, the drum washing machine of the present invention, in addition to the water supply pipe 6 for supplying the washing water via the existing detergent container (5) to perform the shower water supply, the second water supply pipe 22 is added, the door (21) The glass part that allows the user to check the progress of the washing administration among the components is changed as in 'A', and the shower water supply operation is as follows.

When the washing water is sprayed from the second water supply pipe 22, the washing water is hit by the 'A' portion of the upper side of the door 21 and reflected by the spraying force of the washing water to perform shower water supply.

Therefore, the washing water is sprayed through the shower water supply to the laundry rotating on the inner wall of the drum (3), the detergent residues and bubbles contained in the laundry are separated and discharged to the outside by the drainage operation.

Subsequently, a rinsing stroke is performed (S14), and when the rinsing stroke is finished, the next stroke, that is, dehydration or drying is performed (S15), and the pre-washing stroke is terminated.

In this case, the shower water uses a small amount of washing water compared to a normal rinsing stroke.

Therefore, the subsequent rinsing stroke can be simplified compared to the conventional rinsing stroke.

The rinsing method of the drum washing machine according to the present invention reduces the amount of washing water used in the rinsing stroke because rinsing is performed by removing detergent residues and bubbles contained in the laundry through the shower water using a small amount of washing water compared to the rinsing stroke. At the same time there is an effect to improve the rinsing performance.
