In this case, the locking pin 410 passes through a hole (not shown) formed in the front case (not shown) of the locking part 400 to limit the movement path of the locking slider 320 when power is applied. Will rise. When the power is not applied or when the door 50 is required to be opened according to the driving state, the locking slider 320 may be interlocked while descending to the inside of the lock part 400 again.

At this time, the locking unit 400 may further include a position adjusting device for controlling the lifting and lowering movement of the locking pin 410. Here, the position adjusting device may include a configuration such as a bimetal or a solenoid to control the position of the locking pin 410 by electrical control.

In this embodiment, the position adjusting device may be provided with a lifter 420 using bimetal. Bimetal has the property of bending in a specific direction when the temperature is increased by using two metals having different coefficients of thermal expansion and returning to a circular shape when the temperature is decreased.

Thus, as shown in FIG. 7, the lifter 420 is connected to the terminals 421 installed adjacent to the locking pin 410 and to which power is applied. Therefore, when the power is applied, the temperature of the lifter 420 may increase in an upward direction, and when the power is not supplied, the lifter 420 may be installed to return to its original shape while decreasing the temperature of the lifter 420. have. Therefore, the locking pin 410 may be raised and lowered in response to the lift and return of the lifter 420.

However, the lifter 420 is a bimetal due to the nature of the power is applied when the supply is no longer, the temperature is gradually reduced, it takes a predetermined time for the raised locking pin to return to its original shape. Therefore, a problem may occur in that the door 50 cannot be opened for a predetermined time even after the driving is completed.

Therefore, in the present embodiment, a configuration capable of immediately lowering the locking pin 410 by a signal transmitted from the main controller may be separately provided.

One side of the locking pin 410 may be provided with a solenoid 423 for receiving a signal from the main control unit of the clothes processing apparatus to selectively flow a current. In addition, a conductor 424 is provided inside the solenoid 423 to move upward when a current flows. When the conductor 424 is raised, the upper cam 425 is rotated by a predetermined interval by an interlocking structure. You can. In this case, the cam 425 is provided with a tooth (not shown) which slopes downward in the rotational direction, and when the cam 425 rotates, one protrusion of the locking pin 410 is lowered while being caught by the tooth.

Therefore, when the above configuration is provided, the lock state can be released immediately by the signal of the main controller without waiting for a time for the temperature of the lifter 420 to fall.

On the other hand, the clothing treatment apparatus may occur when the door 50 is abnormally opened by an external shock or the like. As such, when the door 50 is abnormally opened, it is preferable to stop the driving of the clothes treating apparatus.

Therefore, the present invention may further include an opening and closing detection unit 500 for detecting the opening and closing of the door 50. In addition, when the opening / closing detection unit 500 detects that the door 50 is abnormally opened, the main control unit preferably controls to forcibly terminate the driving state of the clothes treating apparatus.

In the present embodiment, as shown in Figures 2 to 4, it may be provided with an opening and closing detecting unit 500 is formed so that one end is exposed to the insertion port 610.

Specifically, one end of the opening and closing detection unit 500 may be formed to be exposed to the insertion hole 610 and the other end may be connected to the second elastic member 510 fixed to the inside of the case 600.

Therefore, when the door 50 is not inserted, one end of the opening / closing detection unit 500 is exposed toward the insertion hole 610, and the latch 51 moves to the insertion hole 610 while the door 50 is closed. When inserted, the latch 51 is pressed by the latch 51 so as to slide in the direction perpendicular to the direction in which the door 50 is inserted, that is, the case 600.

Therefore, according to the present embodiment, whether the door 50 is opened or closed may be detected depending on whether the opening / closing detection unit 500 is sliding.

At this time, it is preferable that the inside of the case 600 forms a path through which the opening / closing detection unit 500 slides using a configuration such as a rib.

One end exposed in the direction of the insertion hole 610 is slid in cross section in contact with the latch 51 to be slid inward while being pushed by the latch 51 when the door 50 is inserted. More preferably, it is made to incline in the direction.

When it is detected that the door 50 is abnormally opened by the opening / closing detection unit 500 as in the present embodiment, it is preferable that the clothes treating apparatus controls the driving to be forcibly terminated.

Thus, the open / close detection unit 500 may be electrically connected to the main controller to directly transmit a driving stop signal to the main controller.

However, in the present embodiment, when the open / close detection unit 500 detects that the forcibly opened, it may be configured to control this by using the locking unit 400 electrically connected to the main control unit.

As shown in Figures 2 to 4, the opening and closing detection unit 500 may further include an unlocking rib 520 extending in the vertical direction and the sliding direction. Here, the unlocking rib 520 is slid along with whether the door 50 is opened or closed together with the open / close detection unit 500.

In this case, the unlocking rib 520 is located in a state spaced apart from the point where the locking pin 410 is raised in the state in which the door 50 is closed, and the locking pin 410 when the door 50 is opened. It is preferably made to slide to the point where it rises.

FIG. 8 is a cross-sectional view taken along line AA ′ of FIG. 2. 2 illustrates a state in which the locking part 400 is separated, but in FIG. 8, a cross section of the locking part 400 is illustrated to indicate a positional relationship with the locking pin 410. .

2 illustrates a state in which the door 50 is closed, and when the clothes treating apparatus is driven, the locking pin 410 of the locking part 400 is raised as shown in FIG. 8.

In this case, the door 50 is closed and the opening and closing detection unit 500 is slid into the case 600, and the unlocking rib 520 is fixed in a state spaced apart from the position of the locking pin 410. It is. In addition, the locking slider 320 is limited in moving up and down by the locking pin 410.

At this time, when the door 50 is abnormally opened, as the opening and closing detection unit 500 is slid in the direction of the insertion hole, the unlocking rib 520 is also sliding to press the locking pin 410, the The locking pin 410 is lowered into the locking part 400. That is, when the door 50 is abnormally opened and the locking pin 410 is not lowered by the position adjusting device, the locking part (4) is forcibly locked by the unlocking rib 520 of the opening / closing detection part 500. 400 is to unlock the state.

Here, it is preferable that the unlocking rib 520 forms an inclined surface in the direction of the locking pin 410 so that the locking pin 410 is easily lowered while pressing. In this case, the pressure is gradually made from the upper end of the locking pin 410, the locking pin 410 can be lowered without a hooking phenomenon.

As such, when the door 50 is abnormally opened, the opening / closing detecting part 500 forcibly releases the locking state by the locking pin 410 and locks the fact that the door 50 is opened. It can be delivered to the unit 400.

In this case, the locking unit 400 is electrically connected to transmit and receive a signal with the main control unit. When the lock state is forcibly released, the locking unit 400 transmits a driving stop signal to the main control unit to stop the driving of the clothes processing apparatus. can do.

Alternatively, the locking unit 400 may include a blocking unit (not shown) that may cut off power supplied to the driving unit of the clothes treating apparatus. In this case, when the locked state is forcibly released by the opening / closing detection unit 500, the blocking unit may be configured to cut off the power supplied to the driving unit.

However, this is only an example, and the open / close detection unit 500 includes a sensor (not shown) installed adjacent to the door, and the door 50 is abnormally opened by the open / close detection unit 500. Of course, it is also possible to configure the signal to be sent directly to the main control unit.

Hereinafter, a brief description of the relationship between the locking portion and the opening and closing detection unit according to whether the door is opened or closed.

First, when the door is closed, the opening and closing detection unit is made to slide into the case.

When the operation of the laundry treatment apparatus starts, the locking pin is raised while the power is applied to the locking unit to limit the movement path of the locking slide. Therefore, while the clothing treatment apparatus is in operation, the locking unit maintains a lock state in which the switch unit cannot be interlocked.

Then, when the operation is completed, the locking pin is lowered again by using a configuration such as a solenoid of the locking unit. In this case, when the locking pin is lowered, the locking slide is movable, and it is possible to press the button to open the door. At this time, when opening the door, the opening and closing detection unit is slid in the direction of the insertion hole by the return force of the second elastic member. However, the locking pin is already in the lowered state, the unlocking rib does not press the locking pin.

On the other hand, when the door is abnormally opened during operation, the locking portion may be made so as not to lower the locking pin. Therefore, according to the present embodiment, while the opening and closing detection unit slides in the direction of the insertion hole by abnormally opening the door, the unlocking rib presses the locking pin to force the lowering. In addition, when the locking pin is forcibly lowered, the sensing unit may transmit a driving stop signal to the main control unit or cut off the power supplied to the driving unit of the clothes treating apparatus using the blocking unit.
