When the door is inserted, the hook is rotated while being engaged with the latch, When the rotation position is restrained and the restraint by the shaft is released, the door can be opened to the outside by rotating to the original position by the restoring force of the torsion spring.

The locking unit may further include a position adjusting device that adjusts a position of the locking pin using a power source applied when the clothes processing apparatus is driven.

The position adjusting device may be a bimetal or a solenoid.

The portable terminal may further include an opening / closing detector for detecting whether the door is open or closed.

Here, the opening / closing detection unit may be configured to transmit a signal to the main control unit so as to stop driving the clothes processing apparatus when the door is abnormally opened.

Alternatively, the locking unit may be configured to transmit and receive an electrical signal to and from the main control unit of the clothes processing apparatus, and when the door is detected to be abnormal by the opening / closing detection unit, It may be configured to transmit a drive stop signal.

At this time, it is preferable that the opening / closing sensing unit forcibly releases the locked state of the lock portion when the door is opened abnormally.

According to the present invention, there is provided a door switch assembly for mechanically interlocking with a door using a force by a user to press a button, thereby improving the durability of the door switch assembly.

Furthermore, the present invention provides a door switch assembly that combines mechanical control and electrical control, which further includes a locking portion that can control whether the door is opened or closed in consideration of the driving state of the clothes processing apparatus, And the safety can be achieved.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

However, the present invention is not limited thereto, and the present invention can be applied to any clothes processing apparatus having a door. Furthermore, the present invention can be applied not only to the clothes processing apparatus but also to all the apparatuses provided with the doors that can be opened and closed.

1 is a perspective view showing an outer appearance of a clothes processing apparatus according to a preferred embodiment of the present invention.

The garment treating apparatus shown in Fig. 1 comprises a cabinet 20 forming an outer appearance; A control panel 30 may be provided on the outside of the cabinet 20 to allow a user to operate the operation of the clothes processing apparatus. Here, it is preferable that the control panel 30 is located above the cabinet 20 so that the control panel 30 can be easily operated while the user stands.

Meanwhile, a drum 40 may be provided inside the cabinet 20 to accommodate clothes. The drum 40 is preferably rotatably installed so that the clothes accommodated in washing or drying can be treated evenly.

A door 50 for storing and collecting clothes may be provided in front of the drum 40. In general, the door 50 is provided on one side of the cabinet 20 so as to be openable and closable, and one side thereof may be fixed by a hinge 53 or the like so as to be rotatable. At this time, it is preferable that the door 50 is opened and closed while a side opposite to the portion fixed by the hinge 53 is selectively attached to and detached from the cabinet 20. [

As shown in FIG. 1, a latch 51 may be provided on the rear wall of the door 50 so as to protrude rearward. The door 50 can be opened and closed while the latch 51 is selectively coupled to the cabinet 20 while the door 50 is pivoted about a portion fixed by the hinge 53 or the like .

The door switch assembly 10 may be provided at one side of the cabinet 20 to control opening and closing of the door 50. That is, when the door 50 is closed, the door switch assembly 10 is locked with the latch 51 to fix the door 50. When the door 50 is to be opened, It is possible to release the engagement state with the latch 51 by operating the button 110 provided at one side.

The door switch assembly 10 according to the present invention includes a button unit 100 installed to be operable by a user, a switch unit 50 mechanically interlocked with the input of the button unit 100 to open the door 50 to the outside, And a locking part 400 for maintaining the locking state of the door 50 by restricting the mechanical interlocking of the switch part 300 according to the driving state of the clothes processing device.

Here, the mechanical interlocking is achieved because the respective components of the button unit 100 and the switch unit 300 are coupled to each other so that they can interlock with each other using a force that is pressed through the button unit 100, Quot; That is, in opening the door 50, an additional force such as an electromagnetic force is not used, but only the force that is applied to the button unit 100 is used.

Accordingly, by controlling the opening and closing of the door 50 using a mechanical structure, durability is improved and a more accurate fastening state can be maintained compared with opening and closing the door 50 by using the conventional electromagnetic force.

Hereinafter, the construction of the door switch assembly 10 for the garment disposal apparatus will be described in detail with reference to FIGS. 2 and 4. FIG.

FIG. 2 is a sectional view showing the internal configuration of the door switch assembly in a closed state of the door, and FIG. 3 is a sectional view showing the internal configuration of the door switch assembly in a pressed state. 4 is a cross-sectional view showing the internal configuration of the door switch assembly in which the force applied to the button portion is released when the door is opened.

As described above, the door switch assembly 10 according to the present invention includes a button unit 100 installed to be operable by a user, a door unit 50 mechanically interlocked with an input of the button unit 100, A switch unit 300 for opening the switch unit 300; And a locking part 400 for limiting the mechanical interlocking of the switch part 300 to maintain the locked state of the door 50.

2 and 4 illustrate a configuration in which the lock portion 400 is removed so that the configuration of the switch portion 300 is specifically revealed, and the configuration of the lock portion 400 will be separately described below .

The button unit 100 is a part to be pressed by a user when the door 50 is to be opened and is connected to the switch unit 300 by a member transmitting a force to transmit the pressurized force to the switch unit 300 300). In the present embodiment, it is preferable that the transmission member is connected by a cable 200 as an example of the transmission member.

Specifically, the button unit 100 may include a button 110 provided outside the case 600 so that the user can directly press the button unit 100 from the outside. The slider 130 has one end fixed to the cable 200 and a lever 120 capable of switching the direction of the force applied by the button 110 and transmitting the force to the slider 130. [ have.

Therefore, when the user presses the button 110, the button unit 100 guides the displacement of the cable 200 while the slider 130 is lifted upward, and the switch unit (not shown) connected to the other end of the cable 200 300 are interlocked by the displacement.

The switch unit 300 corresponds to the body of the door switch assembly 10 and is formed adjacent to an insertion port 610 into which the latch 51 of the door 50 is inserted. And may include a cable lever 310, a locking slider 320, a shaft 330, and a rotation cam 340 as shown.

Specifically, the cable lever 310 is connected to the cable 200, and receives the force applied by the user to the button portion by the cable 200. At this time, one end of the cable lever 310 is fixed by the first torsion spring 311, and when the user pushes the button part 100, when the cable 200 is displaced upward, . However, after the user presses the button unit 100, the user can return to the initial position by the restoring force of the first torsion spring 311. [

The locking slider 320 may be connected to the cable lever 310 so that the locking slider 320 can move up and down according to the rotation of the cable lever 310. In the present embodiment, protrusions (not shown) are formed at one side of the cable lever 310, and the locking slider 320 has a long hole (not shown) formed therein. The protrusion is inserted into the long hole Can be connected. Accordingly, when the cable lever 310 rotates upward, the locking slider 320 also moves upward. When the cable lever 310 returns to the initial position, the locking slider 320 also moves downward And return to the initial position.

The shaft 330 is connected to the locking slider 320 in a state where one end of the shaft 330 is fixed, and is rotatable according to the rotation of the locking slider 320. (Not shown) is formed on one side of the shaft to which the shaft is pivoted, a single hole (not shown) is formed inside the locking slider 320, and the projection of the shaft 330 Can be inserted and connected. Therefore, when the locking slider 320 moves upward, the shaft 330 also rotates upward, and when the locking slider 320 returns to the initial position, the shaft 330 can be rotated downward to the shaft 330 have.

Meanwhile, the rotation cam 340 may be rotatably installed adjacent to the insertion port 610. At this time, the rotation shaft 341 may be installed in a direction parallel to the insertion port 610, and a second torsion spring 342 may be provided at one end of the rotation cam 340. Accordingly, when the rotation cam 340 is rotated by an external force, a restoring force can be generated so as to return to the initial position.

On the other hand, the rotation cam 340 preferably includes a cam body 343 having a sector shape in the radial direction of the rotation shaft 341. The rotation shaft 341 may include hooks 344 and 345 protruding in the radial direction of the cam body 343. The hooks 344 and 345 are formed to be exposed to the insertion port 610 according to the rotational position of the rotation cam 340. The hooks 344 and 345 are inserted into the insertion port 610, The cam can be rotated.

The rotation cam 340 according to the present embodiment preferably includes a first hook 344 and a second hook 345. The first hook 344 may rotate the rotation cam 340 while being pushed by the front end of the latch 51 when the latch 51 of the door is inserted. The second hook 345 rotates together with the first hook 344 and is engaged with the fastening hole 52 formed in the inside of the latch 51 to be rotated while being engaged with the latch 51.

2, the latch 51 of the door 50 is inserted into the insertion port 610. As shown in FIG.

The first hook 344 of the rotation cam 340 is pushed rearward by the front end of the latch 51 and the second hook 345 is pushed to the rear by the rotation of the latch 51. As described above, The rotation cam 340 is rotated in the direction of the insertion port 610 while being engaged with the fastening hole 52 of the cam 340.

At this time, a restoring force for returning to the initial position is generated by the second torsion spring 342 formed at one end of the rotation shaft 341. However, when the door 50 is inserted, the cam body 343 is rotated, and one side of the cam body 343 is fixed by one end of the shaft 330 to restrict the rotation position.

At this time, it is preferable that the cam body 343 has a fan shape. The shaft 330 and the cam body 343 are spaced apart from each other at all rotational positions of the rotation cam 340 when the shaft 330 is formed around the rotation shaft 341, This is because the rotation position can not be fixed only by supporting one side of the cam body 343. However, in this embodiment, a cam body 343 having a fan shape is provided, and the shaft 330 supports one side of the cam body 343, so that the rotation position of the rotation cam 340 is restricted .

Therefore, the rotary cam 340 is fixed in its rotational position despite the restitution force to return to the initial position, and the door 50 is rotated in a state in which the latch 51 is engaged with the second hook 345, Is fixed to the assembly (10).

However, the present invention is not limited to the shape of the cam body 343, but may be modified into other shapes so that the rotational position can be constrained by the shaft 330 according to the rotational position. For example, the cam body 343 may have an elliptical shape or a circular shape eccentrically centered on the rotation axis, or may have a stepped portion having a different height depending on the rotation position.

3, the button unit 100 is pressed to open the door 50 by the user.

When the user presses the button unit 100, the cable 200 is pulled upward, and the switch unit 300 connected to the cable 200 is interlocked.

First, the cable lever 310 connected to the cable 200 rotates upward. As the cable lever 310 rotates upward, the locking slider 320 connected to the cable lever 310 is moved upward. The shaft 330 connected to the locking slider 320 also rotates upward.

When the shaft 330 is rotated upward, the rotation cam 340 is released from the state where one side of the cam body 343 is restrained by the one end of the shaft 330. Therefore, by using the restoring force caught by the second torsion spring 342, it is possible to return to the initial position, that is, the position before the door 50 is inserted. At this time, the latch 51 of the door 50 engaged with the second hook 345 is pushed outward as the rotation cam 340 rotates in the direction of the shaft 330, Openness can be achieved.

4 shows a state in which the door 50 is opened and a force applied to the button portion is released.

That is, when the pulling force of the cable 200 is removed through the button unit 100, the cable lever 310 is moved downward by the restoring force of the first torsion spring 311 of the cable lever 310 And the cable 200 is displaced downward again.

Accordingly, the locking slider 320 is also moved downward, and the shaft 330 is also rotated downward to fix the position of the rotation cam 340.

Here, in the present embodiment, the cam body 343 has a fan shape, and the position of the cam body 343 is changed as it returns to the initial position.

2, when the door 50 is closed, the cam body 343 rotates in the direction of the insertion port 610 so that one side of the cam body 343 is fixed by the end of the shaft 330 . However, as the rotation cam 340 returns to the initial position due to the interlocking motion of the switch unit 300, the cam body 343 also rotates in the direction of the shaft 330. Therefore, even if the shaft 330 rotates downward, it can not return to the horizontal state as shown in FIG. 2, but can be caught on the upper side of the cam body 343.

In this case, it is preferable that the shaft 330 is formed so as to be able to fix the rotational position of the rotation cam 340 even when the shaft 330 is seated on the upper side of the cam body 343.

In this embodiment, one end of the shaft 330 is connected to a first elastic member 331 fixed to the inner wall of the case 600, and one end connected to the first elastic member 331 is rotated .

In this case, one end of the shaft 330 is fixed to the first elastic member 331, and a predetermined position of the shaft 330 is inserted into the one hole of the locking slider 320 to fix the position.

Accordingly, the shaft 330 is installed to abut one side of the cam body 343 without holding the elasticity in the vertical direction in a state where the door 50 is closed, so that the position of the rotation cam 340 can be fixed (See Fig. 2)

In contrast, after the door 50 is opened, the shaft 330 is seated on the rotation cam 340, so that the first elastic member 331 is maintained in an upwardly bent state (see FIG. 4). In this case, a restoring force is applied to return the first elastic member 331 to a circular shape. The shaft 330 presses the upper side of the rotation cam 340 downward, .

In other words, the shaft 330 according to the present embodiment may fix the position of the rotation cam 340 while supporting one side of the rotation cam 340 in the horizontal direction according to the rotation position of the rotation cam 340 , The position of the rotation cam 340 may be fixed while the upper side of the rotation cam 340 is pressed.

In this embodiment, since the shaft 330 is fixed by the first elastic member 331, even if the door 50 is closed, the door 50 can be opened There are advantages.

More specifically, the shaft 330 fixes the position of the rotation cam 340 on which the door 50 is engaged. When the door is pressed outward, the rotation cam 340 rotates in the direction of the shaft 330 . At this time, when the shaft 330 is rotatably installed by a fixing member such as a hinge, the rotation cam 340 can not rotate before the fixing member is broken.

When the shaft 330 is connected to the first elastic member 331 as in the present embodiment, the rotation cam 340 can be restrained from the shaft 330 using the deformation of the first elastic member 331, . That is, the shaft 330 can rotate in a horizontal direction at a predetermined interval around a portion connected to the locking slider 320. When the force pressing the door 50 from the inside of the door 50 is equal to or larger than a predetermined size The door 50 can be opened while the restraining state of the rotation cam 340 is released.

Therefore, in this embodiment, when the child is trapped inside the clothes processing apparatus due to carelessness of the user, the child can press the door 50 by the magnetic force to open the door 50, so that the first elastic member 331 The modulus of elasticity can be controlled. That is, the present embodiment provides a door switch assembly 10 of a garment processing apparatus that performs a child protection function.

The door switch assembly 10 according to the present invention may further include a locking part 400 for restricting the mechanical interlocking of the switch part 300 to maintain the locked state of the door 50 have.

As described above, the door switch assembly 10 of the clothes processing apparatus according to the present invention can open the door 50 while mechanically interlocking with the user using a force for pressing the button unit 100 installed outside .

However, in the case where the door 50 of the clothes processing apparatus is dependent on only the mechanical configuration as described above, there is a concern that the door 50 may be opened even when the clothes processing apparatus is driven.

In order to overcome this, the present embodiment may further include a lock portion 400 for selectively limiting the mechanical interlocking of the switch portion 300. Also, the lock unit 400 may be configured to be selectively operated only when the clothes processing apparatus is driven, when the clothes processing apparatus is driven.

Therefore, according to the present embodiment, it is possible to provide the door switch assembly 10 in which the mechanical control and the electric control are combined, and the durability is improved. At the same time, As shown in Fig.

In addition, in the case of a power failure, since the power is not supplied to the lock portion 400, the locked state is automatically released, so that the door portion 50 can be opened by pressing the button portion 100. Therefore, it is possible to prevent the garment from being left inside the clothes processing apparatus for a long period of time due to a failure or the like.

Meanwhile, the locking part 400 of the present embodiment may include a locking pin 410 that blocks the moving path of the locking slider 320 when power is applied.

The locking pin 410 may be installed inside the locking part 400 so that the locking pin 410 may be raised to the outside of the locking part 400 when the power is applied to block the path of the locking slider 320.

As shown in FIGS. 2 to 4, the locking slider 320 may include a locking portion 321 bent in a predetermined shape at a portion adjacent to the locking portion 400. The locking pin 410 may be installed on the inner side of the locking part 400 at a position corresponding to the locking part 321 of the locking slider 320.

In this case, when power is applied to the lock part 400 and the locking pin 410 rises, the path through which the locking slider 320 can move upwardly is restricted, thereby limiting the interlocking of the switch part 300 You can do it.

That is, even if the user pushes the button unit 100 during the operation, the locking slider 320 is restricted from being moved by the locking pin 410, so that the door 50 may not be opened.

FIG. 5 is a cross-sectional view showing the inside of the lock portion according to the present embodiment. Hereinafter, the configuration of the lock portion will be described in detail with reference to FIG.

The locking part 400 is provided with a locking pin 410 which is installed inside and can be raised and lowered by electrical control. Here, the locking pin 410 passes through a hole (not shown) formed in a front case (not shown) of the locking part 400 when power is applied thereto to limit a moving path of the locking slider 320 . When the power source is not applied or the door 50 is required to be opened according to the driving state, the locking slider 320 can be interlocked with the locking slider 320 while descending inside the locking part 400.

At this time, the locking part 400 may further include a position adjusting device for controlling the upward and downward movement of the locking pin 410. Here, the position adjusting device may include a bimetal or a solenoid to control the position of the locking pin 410 by electrical control.

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

Accordingly, as shown in FIG. 5, the lifter 420 is connected to the terminal 421, which is installed adjacent to the locking pin 410 and is powered. Therefore, when the power is applied, the lifter 420 can be lifted upward while the temperature of the lifter 420 is increased, and when the power is not supplied, have. Therefore, the locking pin 410 can be raised and lowered in response to the lifting and returning of the lifter 420.

However, when the lifter 420 is powered on due to the nature of the bimetal, the temperature is gradually reduced when it is no longer supplied, so that it takes a certain time for the raised locking pin to return to its original shape. Therefore, the door 50 can not be opened for a predetermined time after the driving is completed.

Therefore, in the present embodiment, it is possible to separately provide a structure for immediately lowering the locking pin 410 by a signal transmitted from the main control unit.

A solenoid 423 may be provided at one side of the locking pin 410 to selectively receive a signal from the main control unit of the clothes processing apparatus. When the conductor 424 rises, the upper cam 425 is rotated at a predetermined interval by the interlocking structure. In addition, when the conductor 424 is moved upward, . At this time, the cam 425 has teeth (not shown) that are inclined downward in the rotational direction. When the cam 425 rotates, one projecting portion of the locking pin 410 is lowered while being caught by the teeth.

Therefore, in the case of the above configuration, the locked state can be immediately released by the signal of the main control unit without waiting for the time when the temperature of the lifter 420 falls.

On the other hand, the clothes processing apparatus may cause the door 50 to open abnormally due to an external impact or the like. As described above, when the door 50 is opened abnormally, it is preferable to stop driving the clothes processing apparatus.

Accordingly, the present invention may further include an opening / closing detector 500 for detecting opening / closing of the door 50. When the opening / closing detector 500 senses that the door 50 is opened abnormally, the main controller preferably controls the operation of the clothes processing apparatus to be forcibly terminated.

In this embodiment, as shown in FIGS. 2 to 4, the opening / closing sensing unit 500 may be provided to expose one end of the insertion opening 610.

Specifically, one end of the opening / closing sensor 500 may be connected to the second elastic member 510, which is exposed to the insertion port 610 and the other end is fixed to the inside of the case 600.

When the door 50 is not inserted, one end of the opening / closing detector 500 is exposed toward the insertion port 610, and the door 50 is closed so that the latch 51 is inserted into the insertion port 610 The door 51 is pressed by the latch 51 to slide in a direction perpendicular to the direction in which the door 50 is inserted, that is, toward the inside of the case 600.

Therefore, according to the present embodiment, it is possible to detect whether the door 50 is open or closed according to whether the opening / closing detector 500 is slid.

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

One end that is exposed in the direction of the insertion port 610 is slid in a section in contact with the latch 51 so as to be slid inward while being pushed by the latch 51 when the door 50 is inserted More preferably in a direction inclined in the direction of the arrow.

If it is sensed that the door 50 is abnormally opened by the opening / closing detector 500 as in the present embodiment, it is preferable that the garment disposal apparatus control to forcibly stop driving.

Accordingly, the opening / closing detector 500 may be electrically connected to the main control unit and may transmit a driving stop signal directly to the main control unit.

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

As shown in FIGS. 2 to 4, the opening / closing detector 500 may further include an unlocking rib 520 extending in a direction perpendicular to the sliding direction. Here, the lock release rib 520 is slid according to whether the door 50 is opened or closed together with the opening / closing detection unit 500.

At this time, the unlocking rib 520 is positioned apart from a position where the locking pin 410 is raised when the door 50 is closed. When the door 50 is opened, Is slid to a point where it is raised.

6 is a cross-sectional view taken along the line A-A 'in Fig. 2, the lock portion 400 is separated, but FIG. 6 shows a cross-sectional view in which the lock portion 400 is engaged to show a positional relationship with the locking pin 410 .

FIG. 2 shows a state in which the door 50 is closed. When the clothes processing apparatus is driven, the locking pin 410 of the locking part 400 is raised as shown in FIG.

In this case, when the door 50 is closed, the opening / closing sensing unit 500 slides inside the case 600, and the locking release rib 520 is fixed to the locking pin 410 in a spaced- . In addition, the locking slider 320 is restricted from moving in the vertical direction by the locking pin 410.

At this time, when the door 50 is opened abnormally, as the opening / closing sensing unit 500 is slid in the insertion direction, the unlocking rib 520 also slides to press the locking pin 410, The locking pin 410 is lowered to the inside of the locking part 400. [ That is, when the door 50 is opened abnormally and the locking pin 410 is not lowered by the position adjusting device, the lock releasing rib 520 of the opening / 400 can be released from the locked state.

Here, the locking release rib 520 may be formed with an inclined surface in the direction of the locking pin 410 to facilitate lowering the locking pin 410. In this case, since the upper end of the locking pin 410 is gradually pressed, the locking pin 410 can be lowered without causing a latching phenomenon.

When the door 50 is opened abnormally, the opening / closing detection unit 500 may detect that the door 50 is opened by forcibly releasing the locking state by the locking pin 410, (400).

At this time, the lock unit 400 is electrically connected to the main control unit so as to transmit and receive signals. When the lock state is forcibly released, a driving stop signal is transmitted to the main control unit, You can stop it.

Alternatively, the lock unit 400 may include a cut-off unit (not shown) capable of cutting off the power supplied to the driving unit of the clothes processing apparatus. In this case, when the locked state is forcibly released by the opening / closing detector 500, the power supplied to the driving unit may be shut off by using the blocking unit.

The door 50 may be opened / closed abnormally by the opening / closing sensing unit 500. The sensor 50 may include a sensor (not shown) installed adjacent to the door, It is of course possible to transmit the signal to the main control unit directly.

Hereinafter, the operation of the locking part and the open / close detection part according to whether the door is opened or closed will be briefly described.

First, when the door is closed, the opening / closing sensor is slid to the inside of the case.

When operation of the clothes processing apparatus is started, power is applied to the locking unit, and the locking pin rises to limit the movement path of the locking slide. Therefore, during operation of the clothes processing apparatus, the lock pin keeps the locked state in which the switch unit can not be interlocked.

When the operation is completed, the locking pin is lowered again using the configuration of the solenoid of the lock portion. In this case, when the locking pin is lowered, the locking slide can be moved, and the door can be opened by pressing the button. At this time, when the door is opened, the opening / closing sensing part slides in the insertion direction by the returning force of the second elastic member. However, since the locking pin has already been lowered, the locking rib does not press the locking pin.

Meanwhile, when the door is opened abnormally during operation, the locking portion may be configured to prevent the locking pin from being lowered. Therefore, according to the present embodiment, the opening / closing sensing part slides in the insertion direction by abnormal opening of the door, and the locking release lever presses the locking pin down forcefully. When the locking pin is forcibly lowered, the sensing unit may transmit a driving stop signal to the main control unit or shut off power supplied to the driving unit of the clothes processing apparatus by using the blocking unit.
