12, the apparatus control unit 246 rotates the motor 114 in the second rotation direction Q2_1 to rotate the first path I_2 so that the lock member 112 moves in the second direction Q2, .

That is, the first path I_2 applies the second control signal SC_2 to the second switch element SH2 to switch on and the second drive voltage V2 of the second power supply VCC_2 is applied to the motor M, .

At this time, the first path I_1 is not formed in the switched-off state by the first control signal SC_1.

Here, when the second path I_2 is formed, the locking member 112 is moved in the second direction Q2 to unlock the lid assembly 30 and the top cover 30.

The signal waveform diagram shown in Fig. 13 shows the initial detection signal S1 and the detection signal S2 detected by the position detection section 244_2.

That is, when the initial contact point SW1, which is in contact with the lower side 116_2 of the lead 116, is electrically connected to the common contact point U where the upper side 116_1 of the lead 116 is contacted And the detection signal S2 is outputted when the common contact U whose upper side 116_1 of the lead 116 is in contact with the lock contact SW2 whose lower side 116_2 of the lead 116 is in contact is electrically connected to each other .

Here, the first section T1 is a section in which the lock member 112 is held at the unlock point SP1, and the initial detection signal S1 is output.

The second section T2 is a section in which the lock member 112 moves from the unlock point SP1 to the lock point SP2 and the initial detection signal S1 and the detection signal S2 are not outputted.

The third section T3 is a section in which the lock member 112 is held at the lock point SP2 and the detection signal S2 is output.

That is, the device controller 246 included in the device driver 240 controls the motor driver 242 to prevent the motor 114 from rotating when the lead assembly 30 and the top cover 20 are not fastened, And receives the initial detection signal S1 detected by the first detector 244_2.

15, the position of the locking member 112 of the locking device 110 in the second section T2 shown in Fig. 13 is shown.

That is, Fig. 15 shows that the lock member 112 is located between the unlocking point SP1 and the lock point SP2.

The apparatus control unit 246 determines whether the lead assembly 30 is in contact with the magnets formed on the lid assembly 30 and the top cover 20 when the lid assembly 20 is tightened, When the cover 20 is determined to be engaged, the lock member 112 is moved.

The device control unit 246 transfers the first control signal SC_1 to the motor driving unit 242 to move the locking member 112 to the lock point SP2 when the locking member 112 is moved to the locking point SP2 .

At this time, the motor driving unit 242 rotates the motor 114 in the first rotation direction Q1_1 according to the first control signal SC_1 to move the locking member 112 in the first direction Q1.

Here, since the lock member 112 is being moved to the lock point SP2, the device control unit 246 does not receive the initial detection signal S1 and the detection signal S2 from the position detection unit 244_2.

If the detection signal S2 is not transmitted from the position detection unit 244_2 after the lock member 112 has been moved and the first set time has elapsed, the device control unit 246 controls the rotation of the motor 114 to be stopped , It is determined that the laundry is pinched between the lid assembly 30 and the top cover 20, and the lock error information is generated and displayed to the outside so that the user can recognize the lock error information.

That is, in the second section T2, the upper side 116_1 of the lead 116 contacts the common contact U but the lower side 116_2 does not contact the initial contact SW1 and the lock contact SW2. If this state continues for the first set time, the device control unit 246 controls the motor driving unit 242.

Referring to Fig. 16, the position of the locking member 112 of the locking device 110 in the third section T3 shown in Fig. 13 is shown.

16 shows that the lock member 112 is located at the lock point SP2.

When the lock member 112 is moved in the first direction Q1 and is located at the lock point SP2, the upper side 116_1 of the lead 116 contacts the common contact U, The contact detection unit 116_2 is brought into contact with the lock contact SW2 and receives the detection signal S2 from the position detection unit 244_2.

At this time, the device control unit 246 determines that the lock member 112 locks the lid assembly 30 and the top cover 20.

Referring to Fig. 17, the position of the locking member 112 of the locking device 110 in the fourth section T4 shown in Fig. 13 is shown.

That is, Fig. 17 shows that the lock member 112 passes the lock point SP2 and is located at the maximum point SP3.

If the detection signal S2 is not delivered after the elapse of the second set time after the detection signal S2 is received from the position detection unit 244_2, the device control unit 246 controls the locking member 112 to move to the maximum point SP3 It is determined that the lid assembly 30 and the top cover 20 are engaged and disengaged, so that the engagement release information is generated and displayed as an external.

Here, the detachment information may indicate a state in which the laundry is inserted or the lid assembly 30 and the top cover 20 are opened, but the present invention is not limited thereto.

In the fourth section T4, the upper side 116_1 of the lead 116 contacts the common contact U but the lower side 116_2 does not contact the initial contact SW1 and the lock contact SW2.

18 is a flowchart showing a control method of the laundry processing apparatus according to the first embodiment of the present invention.

18 shows a control method for judging whether or not the motor is faulty.

Referring to FIG. 18, when the lead assembly and the top cover are fastened, the motor is rotated in the first rotation direction so that the lock member is moved from the unlock point to the lock point based on the input command (S100).

That is, the device controller 246 judges whether the lead assembly 30 and the top cover 20 are fastened together. When it is judged that the lead assembly 30 and the top cover 20 are fastened, The first control signal SC_1 is transmitted to the motor driving unit 242 so as to move from the unlocking point SP1 to the lock point SP2 located in the first direction Q1 to move the motor 114 in the first rotation direction Q1_1. .

When the motor rotates in the first rotation direction, the driving voltage supplied to the motor is detected (S102), and the detected driving voltage is compared with the set reference voltage to determine whether the motor is faulty (S104).

That is, the voltage detecting unit 244_1 detects the first driving voltage V1 supplied during rotation in the first rotation direction Q1_1 among the first and second driving voltages V1 and V2 supplied to the motor 114. [

At this time, the device controller 246 compares the first driving voltage V1 with the set reference voltage to determine whether the motor 114 is faulty.

That is, when the first driving voltage V1 is lower than the reference voltage, the device controller 246 determines that the motor 114 is faulty. If the first driving voltage V1 is higher than the reference voltage, It is judged that it has operated normally.

If the motor is determined to be faulty, fault information is displayed externally (S106).

That is, when it is determined that the motor 114 has failed, the device control unit 246 displays failure information to the outside to notify the user of the failure of the motor 114.

19 is a flowchart showing a control method of the laundry processing apparatus according to the second embodiment of the present invention.

19 is a control method for judging whether the lid assembly 30 and the top cover 20 are locked or unlocked and whether the laundry is jammed by judging the position of the lock member 112. [

Referring to FIG. 19, it is sensed whether or not the lead assembly and the top cover are fastened (S200).

That is, the device controller 246 senses whether or not the magnets mounted on the lid assembly 30 and the top cover 20 are in contact with each other to determine whether the lid assembly 30 and the top cover 20 are engaged.

The device control unit 246 senses a voltage change due to the change of the magnetic field of the magnet when the lead assembly 30 and the top cover 20 are fastened.

Upon engaging the lead assembly and the top cover, the lock member moves from the unlock position to the lock position on the basis of an input command (S202).

That is, when the lead assembly 30 and the top cover 20 are fastened, the device controller 246 controls the motor driver (not shown) to move the lock member 112 in the first direction Q1 242 to rotate the motor 114 in the first rotation direction Q1_1.

At this time, the lock member 112 moves from the unlocking point SP1 to the first direction Q1 of the lock point SP2.

It is determined whether the lock member is located at the lock point (S204).

That is, the device control unit 246 determines whether the lock member 112 has been moved from the unlock point SP1 to the lock point SP2.

In other words, the position detection unit 244_2 detects the upper side 116_1 and the lower side 116_2 of the lead 116 interlocked with the lock member 112. [

That is, the device control unit 246 can determine the moving position of the lock member 112 through the lead 116 as the lock member 112 and the lead 116 have the same moving distance.

Here, when the locking member 112 is positioned at the unlocking point SP1 before the movement, the position detecting unit 244_2 contacts the upper side 116_1 of the lead 116 to the common contact U, The controller 116_2 contacts the initial contact SW1 to detect the initial detection signal S1 and transmits the initial detection signal S1 to the device controller 246. [

Then, when the unlocking point SP1 is moved to the lock point SP2, the upper side 116_1 of the lead 116 contacts the common contact U and the lead 116 116 contact the lock contact SW2 to detect the detection signal S2 and transmit the detection signal S2 to the device control unit 246. [

As a result of the determination, when the lock member is located at the lock point, it is determined that the lead assembly and the top cover are locked to generate lock information (S206). As a result of the determination, , The controller determines that the lead assembly and the top cover are unlocked and generates lock error information (S208).

That is, when the detection signal S2 is input from the position detection unit 244_2, the device control unit 246 determines that the lead assembly 30 and the top cover 20 are locked, generates lock information, .

When the detection signal S2 is not inputted after the first set time has elapsed at the time of movement of the lock member 112 after the initial detection signal S1 is inputted, the device control unit 246 controls the lead assembly 30 and the top cover The controller 20 determines that the laundry is the laundry bag between the washing machine 20 and the washing machine 20, and generates the lock error information so that the user can recognize it.

At this time, after the lock information generation step (S206), it is confirmed whether or not the lead assembly and the top cover are detached (S210).

That is, after generating the lock information, the device control unit 246 determines whether the lock member 112 is moved from the lock point SP2 to the maximum point SP3.

In other words, after generating the lock information, the device control unit 246 controls the motor driving unit 242 to rotate the motor 114 to move the lock member 112 from the lock point SP2 to the maximum point SP3 .

At this time, when the lock member 112 is moved, the position detecting unit 244_2 does not detect the detection signal S2 because the lower side 116_2 of the lead 116 is separated from the lock contact SW2.

That is, if the detection signal S2 is not inputted after the elapse of the second set time after the detection signal S2 is inputted, the device control unit 246 determines that the lead assembly 30 and the top cover 20 are engaged and disengaged And outputs the engagement release information to the outside.

At this time, the device controller 246 controls the motor 112 to rotate in the second rotational direction (the second rotational direction) when the lock error information or the lock-release information due to the inclusion of the laundry is generated between the lid assembly 30 and the top cover 20 Q2_1 to move the lock member 112 in the second direction Q2 to move to the unlock point SP1.
