The water level sensing unit 9 may be provided in any shape as long as the water level sensing unit 9 can detect the water level in the tub body 31. FIG. And a pressure sensor 93 that seals the free end of the communicating tube and senses a change in the pressure of the air stored in the communicating tube 91. As shown in FIG.

The communicating tube 91 is connected to the first drain pipe 81 so as to communicate with the tub body 31. In this case, the water level inside the communicating tube 91 will be linked to the water level inside the tub body 31.

When water is supplied to the tub body 31 to increase the water level in the communicating tube 91, the air inside the communicating tube 91 will be compressed and the water in the tub body 31 is drained to the communicating tube 91 The pressure sensor 93 senses the level of the inside of the tub body 31 based on the pressure inside the communicating tube 91. As a result, .

The drum 5 includes a drum body 51 rotatably installed in the tub body 31 and a drum inlet 53 communicating with the inlet 11 and the tub inlet 33, .

The drum body 51 may have any shape as long as clothes can be stored. FIG. 1 shows an example in which the drum body 51 is provided in a cylindrical shape.

The drum body 51 may be provided with a through hole 55 for communicating the inside of the drum body with the inside of the tub body. The through hole 55 may include a hole penetrating the circumferential surface of the drum body 51, And a hole penetrating the bottom surface of the drum body 51. Therefore, the water inside the tub body 31 can be supplied to the clothes placed in the drum body 51 through the through holes 55, and water contained in the clothes when the drum body 51 rotates And can be discharged to the tub body 31 through the through-hole 55.

In this case, the bottom surface of the tub body 31 may further include a bearing for rotatably supporting the rotary shaft 65.

The clothes processing apparatus having the above-described structure can prevent foreign matter from remaining in the drum 5 and the tub 3 through the control method shown in Fig. That is, the control method of the clothes processing apparatus of the present invention can prevent foreign matter from remaining on the drum 5 and the tub 3 through the foreign substance removing step S50 proceeding with the drainage step S40.

The foreign matter removal step may be provided in a first rotation step S51 and a second rotation step S53.

3, the first rotating step S51 rotates the drum 5 in either the clockwise or counterclockwise direction F2 through the driving unit 6 to rotate the tub 3 in the clockwise or counterclockwise direction F2, Thereby forming a water flow F1 inside.

4, the second rotating step S53 rotates the drum 5 in the other one of the clockwise direction and the counterclockwise direction (the direction F3 opposite to the direction of the water flow F1) To separate the foreign matter on the outer circumferential surface of the drum 5 from the drum.

The water flow formed inside the tub 3 during the execution of the first rotation step S51 and the second rotation step S53 will separate the foreign matter remaining on the inner peripheral surface of the tub 3 from the tub 3. [

If the first rotation step S51 and the second rotation step S53 are repeated, the functions of the first rotation step S51 and the second rotation step S53 will be the same. That is, when the first rotation step S51 and the second rotation step S53 are repeated, both the first rotation step S51 and the second rotation step S53 form a water flow inside the tub 3 Effect and the effect of separating the foreign substance from the surfaces of the drum and the tub.

The repetition of the first rotation step S51 and the second rotation step S53 may be performed until the end of the drainage step S40. So that foreign matter separated from the tub 3 and the drum 5 is prevented from remaining on the tub 3 or the drum 5. [

The completion (S60) of the drainage step may be performed by a controller (not shown) by determining whether the water level sensed by the water level sensing unit 9 is lower than a preset reference water level.

The reference water level is preferably set to a water level lower than the bottom surface of the drum 5 in the tub 3. This is because the drum 5 and the water can be rubbed only when the water level inside the tub 3 is higher than the bottom surface of the drum.

However, the reference water level may be set to a water level that can be determined that the water inside the tub 3 has been discharged to the outside of the tub. The first rotating step S51 and the second rotating step S53 are repeated even if the water level inside the tub 3 is lower than the bottom surface of the drum. If the water level in the tub 3 is lower than the bottom surface of the drum 3, It can be separated from the drum 5.

It is preferable that the first rotation step S51 and the second rotation step S53 start together when the drainage step S40 starts. However, after the drainage step S40 is started or after the drainage step S40, Lt; / RTI >

In the latter case, the function of the first rotating step S51, which is firstly performed, is to form a water flow inside the tub 3, and the separation of foreign matter from the tub or drum is accelerated by the second rotating step S53, . That is, the first rotation step S51 is started before the start of the drainage step S40, and the second rotation step S53 is started at the same time as the start of the drainage step S40 or at the start of the drainage step S40 Lt; / RTI >

On the other hand, when switching from the first rotation step S51 to the second rotation step S53 and switching from the second rotation step S53 to the first rotation step S51, rotation of the drum 5 Considering the object of the foreign substance removal step (S50) composed of the first rotating step and the second rotating step, the state in which the rotation of the drum is stopped is advantageous as it is short.

When clothes are not stored in the drum 5, the greater the rotation angle of the drum 5 in the first rotation step S51 and the rotation angle of the drum 5 in the second rotation step S53 It will be advantageous.

In the case where the foreign substance removing step S50 is performed in a state where the clothes are not stored in the drum 5, the user inputs a control command (for example, selection of a foreign matter removing course) for cleaning the tub and the drum to the clothes processing apparatus 100 ). ≪ / RTI >

The foreign matter removing path may include a water supplying step (S10) for supplying water to the tub, a drainage step (S40), and a foreign matter removing step (S50). The water supply step S10 is a step of supplying water to the tub 3, and a control unit (not shown) controls the valve 73 to proceed.

Meanwhile, the foreign substance removing step S50 is performed so as to proceed during the control process in which the water supply step S10, the cleaning step S20, the dispersion step S30, the drainage step S40 and the dehydration step S70 are sequentially performed. In this case, it is preferable that the rotation angle of the drum is set to be less than one in the first rotation step S51 and the second rotation step S53. The foreign substance removal step (S50) may weaken the effect of the dispersion step (S30).

The washing step S20 is a step of rubbing the clothes and water supplied in the water supply step S10 to remove foreign substances from the clothes, and the washing step and the rinsing step may be an example. The washing step separates the foreign matter from the clothes through the detergent, and the rinsing step separates the detergent or foreign matter from the clothes after the washing step.

The washing step S20 is a step in which the control unit rotates the drum 5 through the driving unit 6 and the drum 5 is controlled to be rotated 360 degrees or more in the washing step S20. The larger the number of revolutions and the rotation angle of the drum 5, the easier it will be to separate foreign matter from the clothes.

The dispersing step S30 is a step of uniformly dispersing the clothes in the drum 5 after the completion of the washing step S20. In the dehydrating step S70 started after the completion of the draining step S40, Is minimized.

The dewatering step S70 is a step of separating water from the clothes by rotating the drum 5 only in a clockwise or counterclockwise direction with a rotational speed at which the clothes are closely attached to the drum 5. [

Therefore, when the garment is concentrated in a part of the drum 5, a phenomenon in which the rotation center of the drum 5 does not coincide with the rotation axis 65 (eccentricity of the rotation center) occurs during the dehydration step S70 In this case, the drum may vibrate greatly.

The dispersion step S30 is a means for preventing such a problem. The dispersing step S30 should proceed before the start of the drainage step S40 and may be carried out by alternately rotating the drum 5 clockwise and counterclockwise at an angle of less than 360 degrees.

When the dispersion step S30 is completed, the drainage step S40 and the foreign matter removal step S50 are performed.

If the number of revolutions or rotation angle of the drum 5 is excessively large after the completion of the dispersion step S30 and before the start of the dehydration step S70, The clothes uniformly arranged inside the drum may be concentrated in a part of the drum, and the drum 5 may vibrate greatly in the dewatering step S70.

In order to prevent such a problem, the first rotation step (S51) rotates the drum at an angle of 90 degrees or more and less than 360 degrees along the direction of either the clockwise direction or the counterclockwise direction, (S53) may be provided to rotate the drum 90 degrees or more and less than 360 degrees along the other one of the clockwise and counterclockwise directions.

If the drum is rotated at an angle of less than 90 degrees, there is a high possibility that water flow is not formed in the tub 3, and if the drum is rotated by one rotation (360 degrees) or more, The drum 5 can be concentrated in a part of the area.

That is, if each of the rotation stages S51 and S53 is provided to rotate the drum 5 at an angle of 90 degrees or more and less than 360 degrees, water flow is easily formed inside the tub 3 and dispersion step S30 is performed Thereby minimizing the risk that the dispersed garment will be concentrated in some area of the drum.

According to the experimental results, the above-mentioned effect is obtained in that the first rotation step S51 rotates the drum at an angle of 90 degrees or more and 270 degrees or less along one of the clockwise direction and the counterclockwise direction, The second rotation step (S53) was found to be more effective when the drum was rotated at an angle of 90 degrees or more and 270 degrees or less along the other one of the clockwise direction and the counterclockwise direction.

The above-described control method may be applied to a clothes processing apparatus provided in the drum 5 and provided with a stirring unit for stirring clothes.

As shown in FIG. 1, the agitating part 57 is rotatably provided in the drum 5 so as to form a water flow inside the drum 5.

The agitating part 57 may be provided to rotate by the driving part 6 that rotates the drum 5 or may be provided to rotate by a second driving part (not shown) provided separately from the driving part 6 It is possible.

In the former case, the driving unit 6 should further include a sun gear, a planetary gear, and a clutch for rotating only the agitating unit or for rotating the drum and the agitating unit together.

If the agitating part 57 is provided in the drum 5, the washing step S20 may include rotating at least one of the drum 5 and the agitating part 57 to separate foreign matter from the clothes And the dispersing step S30 may include a step of alternately rotating the drum 5 or the stirring part 57 clockwise and counterclockwise at an angle of less than 360 degrees .

However, in the control method of the clothes processing apparatus of the present invention, the rotation axis of the drum is parallel to the ground, or the rotation axis of the drum is perpendicular to the ground, Or more and less than 90 degrees.

The present invention may be embodied in various forms without departing from the scope of the invention. Accordingly, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
