Hereinafter, as an embodiment of a laundry treatment machine according to the present invention, a washing machine will be described in detail with reference to the accompanying drawings.

1 is a front view showing a washing machine according to an embodiment of the present invention. 2 is a block diagram showing a control configuration of a washing machine according to an embodiment of the present invention.

Referring to FIG. 1, a washing machine 10 according to an exemplary embodiment of the present invention includes a cabinet 2 forming an exterior, a control panel 4 disposed above the front surface of the cabinet 2, and the cabinet ( 2) a door 8 for opening and closing the fabric access hole 6 formed on the front surface of the door 2, a tub 21 disposed inside the cabinet 2 and storing wash water, and an inside of the tub (not shown). A drum 20 arranged to be rotatable, a driving device such as a motor 22 for driving the drum 20, a water supply device 12 for supplying washing water into the tub 21, A drainage device (not shown) for draining the wash water in the tub 21 and a circulation connected to the drainage device (not shown) to circulate the wash water in the tub 21 to the upper side of the drum 20. Device 30, 32.

The control panel 4 is provided with an input unit 5 for the user to input the laundry driving conditions, the washing course, and the like, and a display unit 7 for displaying the input state or the driving state. One side of the control panel 4 is provided with a detergent supply unit 9 for temporarily supplying detergent and supplying the tub 21 to the tub 21 together with the wash water being supplied.

The input unit 5 may include a dial, a plurality of buttons, and the like, and the plurality of buttons may include a rack use course button (button) for selecting a washing course using the rack 50 described later.

The drainage device (not shown) includes a drain hose 24 connected to the lower side of the tub 21 to guide the wash water in the tub 21.

The circulator is connected to the drain hose 24 to pump the wash water, and is connected to the circulation pump 30 to guide the wash water to the upper side of the drum 20. The circulation hose 32 is included.

The end of the circulation hose 32 is provided with a spray device 34 for injecting the circulated washing water. The injector 34 comprises a nozzle. Here, the injector 34 is described as being limited to only the circulation hose 32, but is not limited thereto, and the injector 34 is also connected to a water supply hose (not shown) into which washing water is introduced from the outside. Of course it is possible.

In addition, the washing machine 10 further includes a rack 50 mounted inside the drum 20 to which the laundry 60 is placed. The laundry 60 mounted on the rack 50 may include laundry, knit, and coat made of wool. The rack 50 may be fixedly installed in the horizontal direction inside the drum 20. At least one of the rack 50 and the drum 20 may be provided with a coupling part (not shown) for mutual coupling.

In addition, the washing machine 10 includes a sensor unit 14 that detects the water level or the temperature of the washing water in the tub 21. The sensor unit 14 may include a water level sensor, a temperature sensor, and the like.

In addition, the sensor unit 14 may further include a rack sensor (not shown) for detecting whether the rack 50 is attached or detached. When the rack sensor (not shown) detects whether the rack 50 is installed, washing may be performed in the rack use course even if the rack use course is not input to the input unit 5 due to a mistake of the user.

In addition, the washing machine 10 further includes a controller 40 for controlling the operation of the water supply device 12, the circulation pump 30, the motor 22, and the like according to the signal of the input unit 5. .

Referring to the control method of the washing machine according to an embodiment of the present invention configured as described above are as follows.

3 is a flowchart illustrating a control flow of a washing machine according to an embodiment of the present invention.

Referring to FIG. 3, the controller 40 determines whether a washing course using the rack 50 is selected.

When a user inputs a rack use course through the input unit 5, the controller 40 may determine whether to select a rack use course according to a signal input to the input unit 5. However, the present invention is not limited thereto, and the rack sensor (not shown) of the sensor unit 14 detects the installation of the rack 50, and the controller 40 detects a signal detected by the rack sensor (not shown). Of course, it is also possible to determine whether the course is a rack use.

When it is determined that the rack use course is selected, the controller 40 supplies the wash water including detergent to the tub 21 using the water supply device 12 to a predetermined level. The set water level may be set to a level such that the rack 50 is locked or the laundry 60 placed on the rack 50 is locked. (S11)

When water supply is completed, the controller 40 drives the motor 22 to rotate the drum 20. At this time, the controller 40 controls the drum 20 to rotate below a preset setting angle. The setting angle is 90 degrees, for example. That is, the drum 20 is rotated at an angle of less than 90 degrees. In addition, the drum 20 is rotated alternately in the forward and reverse directions. (S12)

When the drum 20 is rotated at an angle of less than 90 degrees, the laundry 60 mounted on the rack 50 may be prevented from falling from the rack 50. Since the laundry 60 is kept on the rack 50, the damage or deformation of the laundry 60 may be minimized. Since the laundry 60 does not fall, the decoration or the attachment generated during excessive flow or friction of the laundry 60 is prevented from being separated.

While the drum 20 is rotated at an angle of less than 90 degrees, the laundry 60 is repeatedly submerged in the wash water, and thus washing may be performed.

Rotation of the drum 20 as described above may be carried out for a first predetermined time. The first preset time may be set differently according to the type or amount of the laundry 60. (S13)

When the set time elapses, the controller 40 drives the circulation pump 30 to circulate the wash water in the tub 21. When the circulation pump 30 is driven, the washing water in the tub 21 passes through the drain hose 24, the circulation pump 30, and the circulation hose 32 in order, and passes the injection device 34. It is sprayed to the upper side of the drum 20 through. (S14)

While washing water is sprayed through the injection device 34, the control unit 40 stops the drum 20 or rotates it at an angle of less than 10 degrees. At this time, the drum 20 may be stopped and then rotated again at an angle of less than 10 degrees. In addition, when the drum 20 is rotated at an angle of less than 10 degrees can be rotated alternately in the forward and reverse directions. (S15)

While the circulated washing water is sprayed through the injector 34, the drum 20 is rotated at an angle of less than 10 degrees and then stopped again, thereby causing the laundry 60 to be placed on the rack 50. You can soak evenly.

 The spraying of the washing water as described above may be performed for a second preset time. The second preset time may be set differently according to the type or amount of the laundry 60. The second set time may be set smaller than or equal to the first set time.

In addition, the above process may be repeated for a predetermined number of times. The set number of times may be set differently according to the type or amount of the laundry 60.

On the other hand, the embodiment was described as limited to supplying the wash water containing the detergent using only the detergent supply unit 9 when the initial water supply of the wash water, but is not limited to this, it is introduced through the water supply device 12 It is also possible to guide the washing water to the injection device 34 side, to spray water to the upper side of the drum 20 by using the injection device (34). When sprayed water is supplied through the injector 34, it is of course possible to control the drum 20 to rotate at an angle of less than 10 degrees.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.
