4 illustrates an example of a control method of the laundry treatment apparatus having the above structure.

The control method of FIG. 4 includes a water supply step of supplying only water to the tub 2 (S10), a detergent supply step of supplying both detergent and water to the tub 2 after completion of the water supply step (S40), and a washing step (S80) of separating foreign substances from the washing object by rotating the drum 7 after the detergent supply step is completed.

The water supply step (S10) is a step of supplying water without detergent to the tub 2, and the controller (not shown) controls the tub water supply pipe valve 331 to open the tub water supply pipe 33. can proceed by doing

Meanwhile, the water supply step (S10) is a step of supplying water to the tub 2 through a chamber in which no detergent is stored among the three

chambers

511, 512, and 513 provided in the detergent storage unit 5. It may be provided as

That is, the water supply step (S10) is performed through a chamber in which detergent is not stored among the first chamber 511, the second chamber 512, and the third chamber 513 provided in the drawer 51. A step of controlling the first valve 341 and the second valve 342 so that water is supplied to the tub 2 may be provided.

For example, when detergent is stored in the first chamber 511, the water supply step (S10) is provided to supply water only to the second flow path 544 by operating the second valve 342. Alternatively, both the first valve 341 and the second valve 342 may be operated to supply water only to the third passage 545 .

If detergent is stored in the second chamber 512, the water supply step (S10) may be provided to supply water only to the first flow path 543 by operating the first valve 341, Both the first valve 341 and the second valve 342 may be operated to supply water only to the third passage 545 .

Similarly, if detergent is stored in the third chamber 513, the water supply step (S10) may be provided to supply water only to the first flow path 543 by operating the first valve 341, , It may be provided to supply water only to the second flow path 544 by operating the second valve 342 .

Which chamber contains detergent and which chamber is empty can be determined by information input by the user through the input unit 151, and is provided in the detergent storage unit 5 to determine whether or not each

chamber

511, 512, 513) may proceed through a sensor that detects whether or not detergent is stored.

The water supply step (S10) proceeds until the water level inside the tub 2 reaches a preset first water level (S20).

The water supply step (S10) is a process for minimizing the discharge of the detergent supplied through the detergent supply step (S40) to the first drain pipe 41 through the drain hole 213 (forming a water barrier in the drain hole). process), it is preferable that the first water level is set to a water level that prevents the drain hole 213 from being exposed.

5 (a) shows a case where the first water level is set to a water level (L2) higher than the outlet 213 and lower than the lowest point of the drum 7 as an example. If the heater 25 is provided inside the tub body 21, the first water level may be set to a water level L1 at which the heater 25 is submerged. This is because the step of heating the water by operating the heater 25 may be started after the completion of the water supply step ( S10 ) in order to accelerate the dissolution of the detergent.

FIG. 5 (a) shows a case where the water supply step (S10) proceeds through the tub water supply pipe 33, but as described above, the water supply step (S10) of the detergent storage unit 5 Water may be supplied to the tub through the

empty chambers

511, 512, and 513.

Whether or not the water level inside the tub body 21 has reached the first water level (S20) is performed through the sensing unit 8, and the sensing unit 8 determines the even water level inside the tub body 21. When it is detected that the first water level has been reached, the water supply step is terminated (S30).

As shown in FIG. 4, the detergent supply step (S40) may be provided to be started when the water supply step is finished (S30).

The detergent supply step (S40) is a step of supplying the detergent stored in the detergent storage unit 5 together with water to the tub body 21, and is performed by controlling the opening and closing of the storage

water supply pipes

311 and 312. .

That is, in the detergent supply step (S40), water is supplied to the chambers in which the detergent is stored among the first chamber 511, the second chamber 512, and the third chamber 513 provided in the drawer 51. It may be provided as a step of controlling the first valve 341 and the second valve 342 as much as possible.

For example, if detergent is stored in the first chamber 511, the detergent supply step (S40) is a process of supplying water only to the first flow path 543 by operating the first valve 341. When the detergent is stored in the second chamber 512, the second valve 342 is operated to supply water only to the second flow path 544, and the third chamber 513 If the detergent is stored in , both the first valve 341 and the second valve 342 are operated to supply water only to the third passage 545 .

As shown in FIG. 5 (b), the detergent supply step (S40) may proceed until reaching the second water level (L3) set higher than the lowest point of the drum body (71) (S50). This is to allow water inside the tub body 21 to be supplied to the clothes inside the drum body 71 .

The second water level may be determined according to the amount of clothes put into the drum body 71 (the amount of laundry objects and the amount of clothes). In this case, as shown in FIG. 4 , the control method may proceed before starting the detergent supplying step (S40) and proceed to the laundry quantity determination step (S15) of detecting the amount of clothes stored in the drum 7. .

The laundry amount determination step (S15) may be performed in various ways. A method of determining the amount of laundry based on the amount of current supplied to the stator 741 while rotating the drum 7 to a predetermined reference angle, or supplying a predetermined amount of power to the stator 741 and then A method of determining the amount of laundry by measuring the rotation angle of the drum will be an example. However, it is preferable that the second water level (L2) is set to increase in proportion to the amount of laundry objects stored in the drum (7).

When the water level of the tub body 21 reaches the second water level L3 (S50), the detergent supplying step (S40) of supplying detergent and water to the tub is finished (S60).

The washing step (S80) may be provided to be started when the detergent supplying step (S40) is completed. The washing step (S80) may be set to a step of separating foreign substances from clothes by performing clockwise rotation and counterclockwise rotation of the drum 7 alternately by controlling the driving unit 74. Unlike the above, in the washing step (S80), the rotation direction of the drum may be set only clockwise or counterclockwise.

To facilitate the separation of foreign substances from clothes, a dissolving step (S70) of dissolving the detergent in water may be further provided before the start of the washing step (S80). The melting step (S70) may be provided as a step of rotating the drum 7 at a lower rotational speed than the rotational speed set in the washing step.

In the melting step (S70), the drum may be set to rotate clockwise and counterclockwise alternately, or may be set to rotate in only one of the two directions. In addition, the melting step (S70) may be provided to heat the water by operating the heater 25 together with the rotation of the drum.

The above-described control method minimizes the possibility that the detergent supplied in the detergent supply step (S40) is discharged to the first drain pipe 41 through the drain hole 213 through the water supply step (S10), so that the detergent is insufficient. It is possible to prevent the deterioration of washing performance due to

Since the above-described structure and control method of the laundry treatment apparatus are related to embodiments, the scope of rights of the present application is not limited to the above-described embodiments.
