The drainage level of the mixed solution through the siphon mechanism 58 corresponds to the projected height of the siphon tube 60 protruding from the bottom surface of the third detergent container 56C.

When the mixed liquid level of the softener and the water reaches the drainage level as described above and the drainage of the mixed liquid proceeds through the siphon mechanism 58, the water supply valve 30 is shielded to supply water to the water by the water supply device 22. Is blocked (see S3, S4).

At this time, the water supply valve 30 is shielded for a second set time, the second set time is the liquid mixture of the softener and water stored in the third detergent receiving portion 56C is completely drained through the siphon mechanism 58 It's time to finish.

When the mixed solution of the softener and the water is completely drained through the siphon mechanism 58, the drum washing machine 1 compares the number of times of water supply and the set number of times of the water supply device 22 to determine the softener through the siphon mechanism 58. It is determined whether the draining operation is repeatedly performed (see S5).

That is, when the number of times water is supplied to the third detergent storage unit 56C by the water supply device 22 is less than the set number of times, the water supply valve 30 of the water supply device 22 is opened again for the first set time. After the water is supplied to the third detergent receiver 56C, the water is shielded again for a second set time.

The first set time, the second set time and the set number of times are variously set according to the design conditions of the detergent box 50, as compared to the conventional water supply valve 30 is opened for 20 seconds, and the present invention and Likewise, if the water supply valve 30 is opened for 5 seconds and then shielded for 5 seconds is repeated four times, the drainage performance of the softener is greatly improved.

On the other hand, if the number of times water is supplied to the third detergent storage unit 56C by the water supply device 22 is more than a predetermined number of times, the water supply to the third detergent storage unit 56C is stopped, and the Water is supplied to the first detergent accommodating part 56A or the second detergent accommodating part 56B so that water is supplied to the inside of the tub 4 up to the rinsing level. (See S6)

Of course, even if the number of times the water is supplied to the third detergent storage unit 56C by the water supply device 22 is less than the set number of times, the first detergent storage unit 56A or the second detergent storage unit 56A or the second water supply unit 22 is set by the water supply device 22. It is also possible that water is supplied to the detergent container 56B and water is supplied to the tub 4 up to the rinsing level.

As described above, when the softener is supplied to the inside of the tub 4 and water is supplied to the rinsing water level, the drum 6 is inverted left and right by the motor 10 to rinse the laundry.

For reference, the same reference numerals are given to the same or similar constituent elements, and a detailed description thereof will be omitted.

In the washing method of the drum washing machine according to another embodiment of the present invention, as shown in Figure 5, the water supply in the process of water is supplied to the third detergent receiving portion (56C) for the first set time by the water supply device 22 The water supply valve 30 of the device 22 is intermittently opened and closed at short time intervals (see S1, S1 ', S2), and other washing methods proceed in the same manner as in one embodiment of the present invention.

That is, since water is intermittently injected through the injection hole 48B of the dispenser cover 44 by the water supply device 22, the softener of the third detergent accommodating part 56C is cohesive by water intermittently injected. This crushing improves the solubility of the softening agent.

Therefore, this embodiment has the effect that the first set time and the set number of times of the water supply valve 30 is reduced compared to the embodiment.

Thus, with reference to the drawings illustrating a washing method of the washing machine according to the present invention, powder detergent is put into the first detergent receiver 56A and the second detergent receiver 56B and the third detergent receiver 56C. Although a softening agent in a liquid state has been described as input, the present invention is not limited to the above embodiments and drawings, and various modifications are possible by those skilled in the art within the scope of the technical idea of the present invention.

That is, the present invention is not limited to the liquid softener supplied during rinsing, but also for all detergents supplied through the siphon mechanism during the washing process, that is, the liquid bleach or the liquid detergent used for the main washing and the priming washing. Of course, it is applicable.

In the washing method of the washing machine according to the present invention configured as described above, since the water is repeatedly supplied and stopped by the water supply apparatus and the detergent is drained at least twice through the siphon mechanism formed in the detergent receiving portion of the detergent box, the siphon mechanism Through the drainage performance of the detergent is securely secured there is an advantage that the washing performance of the washing machine is stabilized.

In addition, if the drainage performance of the detergent is secured through the siphon mechanism, since the detergent contained in the detergent accommodating portion is completely drained through the siphon mechanism, the phenomenon that the detergent remains or adheres to the detergent accommodating portion is prevented. There is this.

In addition, there is an advantage that the deterioration of aesthetics of the detergent box and clogging of the siphon mechanism, which may be caused by the remaining or fixed detergent in the detergent accommodating part, is prevented.

In addition, the water supply device intermittently sprays water into the detergent receiving portion during water supply, so that the detergent in the detergent receiving portion is finely crushed by the water sprayed from the water supplying apparatus so that the solubility of the detergent is improved, thereby The drainage time of the detergent through the phone mechanism is also advantageous.
