The door latch 73 may be in contact with the upper end of the latch opening 20', thereby interfering with its upward movement. The door latch 73 may be in contact with the lower end of the latch opening 20', thereby interfering with its downward movement.

An elastic member 78 may be coupled to a portion of the door latch 73 accommodated in the door 20. The elastic member 78 may be disposed on the inside of the door 20. Since the elastic member 78 is coupled to the door latch 73 and the door 20 located below the door latch 73, it can provide the door latch 73 with an elastic force that directs the door latch 73 downward. You can.

Door latch 73 can move beyond latch guide 76 when door 20 is in the closed position. More specifically, the contact surface 73'' formed on the hook portion 73n of the door latch 73 is located rearward beyond the end of the latch guide 76 when the door 20 is in the closed position. You can.

Since the door latch 73 receives an elastic force pointing downward, when the door 20 is in the closed position, the lower end of the hook portion 73n may be located lower than the end of the latch guide 76.

When the door 20 is moved from the closed position to the open position, the contact surface 73'' of the hook portion 73n moves forward and may contact the end of the latch guide 76.

The contact surface 73'' of the hook portion 73n may be disposed at a predetermined angle with the support portion 73m. The support portion 73m may extend toward the rear of the door 20. Accordingly, the contact surface 73'' may be disposed at a predetermined angle with the angle facing the rear of the door 20.

The predetermined angle may not be vertical. The predetermined angle may be an angle that prevents the latch guide 76 from restricting the movement of the hook portion 73n when the contact surface 73'' of the hook portion 73n moves forward.

The lower end of the hook portion 73n is moved higher than the end of the latch guide 76, the door 20 is opened, and the door latch 73 can be moved forward. Thereafter, the lower end of the hook portion 73n comes into contact with the latch guide 76, so that the door latch 73 can be moved. This is because the door latch 73 receives elastic force from the bottom.

The door latch 73 may be moved to the outside of the body through the hook opening 75 and/or the insertion opening 17. Thereby, the door 20 can be moved to the open position.

The latch may include an elastic member 78 connecting the latch body 72 and the door 20 between the latch body 72 and the door 20 to elastically bias the key door 71 downward. there is. Due to this, the lower end of the door latch 73 cannot move beyond the latch guide 76.

The door latch 73, which moves forward by the transmission member 61, can be moved upward by the opening and closing device 60. When the door latch 73 moves beyond the end of the latch guide 76, the door latch 73 can move forward along the latch guide 76.

In this case, the elastic member 78 moves the door latch 73 downward, so the door latch 73 can move downward along the latch guide 76.

The latch guide 76 may be formed to protrude from the insertion opening 17 toward the inside of the main body.

The door latch 73 can move along the latch guide 76. The door latch 73 can move while contacting the latch guide 76.

The door latch 73 may include a support portion 73m that protrudes from the door 20 toward the rear of the door 20 .

The door latch 73 may include a hook portion 73n that is bent at the support portion 73m to form a hook shape. The hook portion 73n may extend from the support portion 73m and extend upward or downward. However, for convenience of explanation, it is assumed that the hook extends downward.

The hook may include a contact surface 73'' facing the rear of the door 20.

When door 20 is in the closed position, door latch 73 may contact latch guide 76. More specifically, the door latch 73 may contact the end of the latch guide 76. When the door 20 is in the closed position, the end of the latch guide 76 may contact the support portion 73m of the door latch 73. The end of the latch guide 76 may simultaneously contact the support portion 73m and the hook portion 73n of the door latch 73.

The cooking appliance may include an elastic member 78 that elastically presses the door latch 73. The elastic member 78 can press the door latch 73 downward. However, the fact that the elastic member 78 presses the door latch 73 downward is only set according to the bending direction of the hook portion 73n of the door latch 73 and the inclination direction of the latch guide 76, and the hook If the bending direction of the portion 73n and the inclination direction of the latch guide 76 are different, the direction in which the elastic member 78 presses the door latch 73 may change correspondingly.

The cooking appliance 1 may include a latch that interacts with the opening and closing of the door 20 . More specifically, the latch can lock or unlock the opening of the door 20. Here, locking the opening of the door 20 not only means preventing the door 20 from moving, but also means preventing the door 20 from moving without applying force and preventing disturbances not included by the user. This includes the meaning of making it difficult for the door 20 to be opened.

The elastic member 78 can connect the door latch 73 and the door 20. One end of the elastic member 78 may be coupled to the door latch 73. The other end provided in a position opposite to one end of the elastic member 78 may be coupled to the door 20. Accordingly, the elastic member 78 can apply elastic force in a compressing direction. Since the door 20 does not substantially move due to the elastic member 78, it can be said that the elastic member 78 moves the door latch 73.

A portion of the door latch 73 may be disposed on the inside of the door 20, and a portion of the door latch 73 may protrude toward the rear of the door 20.

An elastic member 78 may be coupled to a portion of the door latch 73 accommodated in the door 20. The elastic member 78 may be disposed on the inside of the door 20. Since the elastic member 78 is coupled to the door latch 73 and the door 20 located below the door latch 73, it can provide the door latch 73 with an elastic force that directs the door latch 73 downward. You can.

Door latch 73 can move beyond latch guide 76 when door 20 is in the closed position. More specifically, the contact surface 73'' formed on the hook portion 73n of the door latch 73 is located rearward beyond the end of the latch guide 76 when the door 20 is in the closed position. You can.

Since the door latch 73 receives an elastic force pointing downward, when the door 20 is in the closed position, the lower end of the hook portion 73n may be located lower than the end of the latch guide 76.

When the door 20 is moved from the closed position to the open position, the contact surface 73'' of the hook portion 73n moves forward and may contact the end of the latch guide 76.

The contact surface 73'' of the hook portion 73n may be disposed at a predetermined angle with the support portion 73m. The support portion 73m may extend toward the rear of the door 20. Accordingly, the contact surface 73'' may be disposed at a predetermined angle with the angle facing the rear of the door 20.

The predetermined angle may not be vertical. The predetermined angle may be an angle that prevents the latch guide 76 from restricting the movement of the hook portion 73n when the contact surface 73'' of the hook portion 73n moves forward.

Accordingly, when the user manipulates the door handle 900, the door 20 can be moved from the locked state to the unlocked state.

The lower end of the hook portion 73n is moved higher than the end of the latch guide 76, the door 20 is opened, and the door latch 73 can be moved forward. Thereafter, the lower end of the hook portion 73n comes into contact with the latch guide 76, so that the door latch 73 can be moved. This is because the door latch 73 receives elastic force from the bottom.

The latch may include an elastic member 78 connecting the latch body 72 and the door 20 between the latch body 72 and the door 20 to elastically bias the key door 71 downward. there is. Due to this, the lower end of the door latch 73 cannot move beyond the latch guide 76.

FIG. 6 shows the connection relationship of the control unit for controlling the heating source of the cooking appliance 1 shown in FIG. 2 based on information detected by the sensor 76 of the cooking appliance 1 shown in FIGS. 3 to 5. This is a control block diagram shown.

Referring to FIG. 6, control of the control unit by the sensor 76 will be described.

The cooking appliance 1 may include a sensor 77. Sensor 77 may include a first sensor 77a and/or a second sensor 77b. The first sensor 77a may be provided to contact the transmission member 61. The second sensor 77b may be provided to contact the door latch 73. The first sensor 77a may transmit a signal to the control unit 56 to stop the operation of the heating source 51 when the transmission member 61 rotates and is separated from the transmission member 61. there is. As the door latch 73 moves, the second sensor 77b is released from contact with the door latch 73 and, when separated, can transmit a signal to the control unit 56 to stop the operation of the heating source 51. there is. The control unit 56 may be provided to control the high-pressure transformer 53 and/or the high-pressure condenser 54.

That is, the cooking appliance 1 includes a sensor 77 provided to be in contact with the door latch 73, a control unit 56 electrically connected to the sensor 77, and a heating source electrically connected to the control unit 56 ( 51) may be included. When the door latch 73 is spaced apart from the sensor 77 as the opening and closing device 60 is operated, the control unit 56 may control the heating source 51 so that the operation of the heating source 51 is stopped.

When the cooking appliance 1 described above operates, the cooking object accommodated in the cooking chamber 41 is heated. When the cooking object is heated, the air received in the cooking chamber 41 becomes hot. If the door 20 is opened while the air in the cooking chamber 41 is heated, the hot air may be directed toward the user. This may cause injury to the user.

To prevent this, the door 20 can be opened by two operations. More specifically, in order to open the door 20 by several movements, the cooking appliance may include a door lock 100.

The door lock 100 may be configured to interfere with the opening of the door 20 . Alternatively, the door lock 100 may be configured to interfere with or cancel the opening of the door 20.

Hereinafter, the configuration of the door lock 100 will be described.

FIG. 7 is an exploded view showing the door 20 and the control panel 30 of the cooking appliance 1 shown in FIG. 1 spaced apart.

Referring to FIG. 7, the configuration provided on the front side of the cooking appliance 1 will be described.

A locker 200 including a door 20, a front panel 16, a control panel 30, and a door lock 100 may be provided on the front side of the cooking appliance.

The front panel 16 may be placed in front of the cooking appliance 1. The front panel 16 may be provided in front of the external case 11 to form the front exterior of the external case 11. Since the outer case 11 forms the exterior of the main body 10, the front panel 16 can form the front exterior of the main body 10.

The door 20 may be placed in front of the front panel 16. Door 20 may be placed adjacent to the left or right side of front panel 16. This is because the door 20 and the front panel 16 can be pivotably coupled by the hinge 28.

The door 20 may have a substantially rectangular parallelepiped shape. The height of the door 20 may be formed to be substantially the same as the height of the front panel 16. Accordingly, the door 20 can cover at least a portion of the front of the front panel 16.

The side of the door 20 may have a flat surface.

The control panel 30 may be placed in front of the front panel 16. The control panel 30 may be placed adjacent to the door 20. More specifically, the control panel 30 may include a locking surface 36 (FIG. 13) facing the door 20. The locking surface 36 will be described in detail with reference to the related drawings.

The control panel 30 may be placed adjacent to the left or right side of the front panel 16 where the door 20 is placed, but not on the right or left side where the door 20 is not placed. Through this, the control panel 30 can cover the front of the front panel 16 together with the door 20.

The front panel 16 may include a control opening 16' open in the front-to-back direction at a position where the control panel 30 is coupled.

As mentioned earlier, the battlefield room 50 may be provided behind the front panel 16. Electrical equipment placed in the electrical equipment room 50 can be connected to the control panel 30 and receive signals. The control panel 30 may be placed in the front of the electrical equipment room 50 in order to be connected to electrical equipment placed in the electrical equipment room 50 with a shorter conductor.

To this end, the front panel 16 may include an opening through which a conductive wire passes so that it can be connected to the electrical equipment placed in the electrical equipment room 50, corresponding to the position where the control panel 30 is coupled.

Since the galley compartment 41 may be formed inside the inner case 40, the electrical compartment 50 may be provided outside the inner case 40. Since the outer case 11 can form the exterior of the main body 10, the electrical equipment compartment 50 can be placed between the outer case 11 and the inner case 40. Accordingly, the electrical equipment compartment 50 may be created between the side of the inner case 40 and the outer case 11. Accordingly, the control panel 30 can be arranged adjacent to the left or right side of the front panel 16.

The control panel 30 may have a substantially rectangular parallelepiped shape.

As seen above, when the cooking appliance 1 is operated, the cooking object located inside the cooking chamber 41 may be heated. When the cooking object is heated, the air located inside the cooking chamber 41 may be heated together with the cooking object or may be heated by the cooking object. That is, when the cooking appliance 1 operates, the air inside the cooking chamber 41 may be heated. When the air inside the cooking chamber 41 is heated and the door 20 is opened, the heated air may flow toward the user. Users may get burned by heated air.

To prevent this, it may be necessary to open the door 20 by two or more operations.

For this purpose, the cooking appliance 1 may include a door lock 100.

The door lock 100 may be configured to interfere with the movement of the door 20. As a result, the door 20 can move from a closed position that closes the galley 41 to an interference position that is interfered with by the door lock 100.

The interference position may be a position where the door 20 is interfered with by the door lock 100 and may also be a position where the door 20 is open without opening the galley 41 to the front. The interference position may mean a specific position among the positions where the door 20 is opened. However, the interference position may not mean that the door 20 is completely open.

When the door 20 moves to the interference position, heated air inside the cooking chamber 41 may escape to the outside. Instead, since the cooking chamber 41 is not completely open, the user cannot take out the cooking object accommodated in the cooking chamber 41 to the outside.

If the door 20 is in an interference position, by releasing the door lock 100 from interfering with the door 20, the door 20 can be moved to the open position. The open position may mean that the galley 41 is completely open. The open position may mean an open position in which the front of the galley 41 is open.

While the door 20 releases the interference of the door 20 of the door lock 100 at the position where the door 20 interferes, hot heat from the cooking chamber 41 may be emitted to the outside of the cooking appliance 1. Accordingly, even if the user places the door 20 in the open position after cooking the food, damage caused by hot air in the cooking chamber 41 can be prevented.

At this time, the door lock 100 may be positioned in a first position that interferes with the door 20 so that the door 20 moves between the closed position and the interference position. The door lock 100 can be positioned in a second position where the door 20 can be moved from the interference position to the open position so that the interference with the door lock 100 is released.

More specifically, the interference portion 210 of the locker 200 included in the door lock 100 may be located at the first position and the second position. This will be described in more detail later with reference to the related drawings.

The door lock 100 is coupled to a locker 200 coupled to either the door 20 or the control panel 30 and to one other than either the door 20 or the control panel 30, and mutually It may include an acting guide 300 (FIG. 13).

The locker 200 may be coupled to the door 20 or the control panel 30. The guide 300 that interacts with this may be coupled to the control panel 30 facing the door 20, or may be coupled to the door 20 facing the control panel 30. It is sufficient for the locker 200 and the guide 300 to be arranged so that they can interact with each other, and their coupling positions are not limited to specific positions. Furthermore, if there is a counterpart provided adjacent to the door 20 other than the control panel 30 among the components included in the main body 10, a locker 200 or a guide 300 may be provided thereon.

However, for convenience of explanation, the description below will be made on the basis that the locker 200 is coupled to the door 20, as shown in FIG. 7.

In other words, the cooking appliance 1 is disposed between the door 20 and the control panel 30 and includes a locker 200 coupled to the door 20 in order to open the door 20 through two operations. may include.

The locker 200 may protrude toward the guide 300. The guide 300 may prevent the door 20 from being completely opened due to the locker 200 being caught.

When the locker 200 is manipulated by the user, its shape can change so that the door 20 is completely opened. Through this, the user needs to additionally perform an operation to manipulate the locker 200 in order to completely open the door 20. Accordingly, two or more operations may be required for the user to open the door 20.

The door lock 100 may include a locker 200 coupled to either the main body 10 or the door 20. The guide 300 may be provided on one of the main body 10 or the door 20 rather than the one to which the locker 200 is coupled. For convenience of explanation, this embodiment will be described assuming that the locker 200 is provided in the door 20 and the guide 300 is provided in the main body 10.

At this time, the door 20 may be in an open position. The position where the door 20 is opened may be referred to as the open position. The open position is an interference position in which the opening of the door 20 is interfered with by the locker 200 and the guide 300 and/or an opening in which the door 20 releases the interference of the interference unit 210 and is more open than the interference position. May include location.

The locker 200 may have a first position and a second position according to the user's manipulation. The first position is a position that can interfere with the movement of the door 20. The second position is a position that allows movement of the door 20. The locker 200 can change its shape and have different positions, thereby allowing different interactions with the guide 300. By this, the door 20 may or may not be fully open. This will be described in detail later when the relevant drawings are mentioned.

For reference, the locker 200 may be combined with the door 20. FIG. 7 shows that the locker 200 is located at the center of the side height of the door 20. However, it is not limited to this, and may be located higher than the center of the side height of the door 20, or may be located lower than the center of the side height of the door 20. However, the fact that the locker 200 is located at the center of the side height of the door 20 can provide the user with a sense of aesthetic stability of the door 20. For the user's convenience, the locker 200 may be provided at a location within the user's comfortable reach.

Furthermore, the locker 200 may be coupled to the top or bottom of the door 20. In this case, the guide 300 that interacts with the locker 200 may be located at the top or bottom of the main body 10, arranged to correspond to the locker 200, and configured to interact with the locker 200.

Let’s take a closer look at the locker 200.

FIG. 8 is an enlarged view showing the locker 200 coupled to the door 20 of the cooking appliance 1 shown in FIG. 1.

Referring to FIG. 8 , a locker 200 and a door 20 to which the locker 200 is combined will be described.

That is, the insertion groove 910 and the guide groove 920 can facilitate coupling the locker 200 to the door handle 900.

FIG. 14 is a perspective view showing the control panel 30 of the cooking appliance 1 shown in FIG. 7 from another angle. FIG. 15 is an enlarged view of the catching groove 310 of the cooking appliance 1 shown in FIG. 14.

With reference to FIGS. 14 and 15 , the guide 300 will be described.

The control panel 30 may be placed adjacent to the door 20. The control panel 30 may have a substantially rectangular parallelepiped shape. The control panel 30 may include a locking surface 35 that faces the door 20 when the door 20 is in the closed position.

The door lock 100 may include a guide 300 disposed on the locking surface 35 of the control panel 30. The guide 300 may contact the locker 200 to limit the opening of the door 20 when the locker 200 is in the first position.

The guide 300 may have a groove shape to accommodate at least a portion of the interference portion 220.

The guide 300 may include a locking groove 310 that is concave toward the inside of the control panel 30.

The catching groove 310 may include a base surface 311 facing the interference portion 210. The base surface 311 may be formed so that a portion protruding toward the base surface 311 of the locker 200 corresponds to a moving path so as not to interfere with the movement of the locker 200. Alternatively, the base surface 311 may retreat to the inside of the control panel 30 so that the interference portion 210 of the locker 200 does not contact the locker 200 to allow movement of the locker 200.

The locking groove 310 may include a locking surface 312 that is bent from the base surface 311 and extends toward the door 20 . The locker 200 may be in contact with the locking surface 312. More specifically, the interference portion 210 of the locker 200 may contact the engaging surface 312.

The engaging surface 312 may include a first engaging surface 312a disposed at the front and a second engaging surface 312b disposed at the rear.

The first locking surface 312a may contact the interference portion 210 of the locker 200 to impede the movement of the door 20 when the door 20 is moved from the closed position to the open position. More specifically, the step portion 212 of the locker 200 may contact the first engaging surface 312a. Since the step portion 212 of the locker 200 may have a shape extending toward the coupling plate 221, the first engaging surface 312a may be formed to be perpendicular to the base surface 311.

The second locking surface 312b may contact the inclined portion 211 of the locker 200 when the door 20 is in the closed position. Since the inclined portion 211 may extend in the front-back direction to be inclined forward, the second locking surface 312b may be formed to be inclined forward. In other words, the base surface 311 and the second engaging surface 312b may be disposed at a predetermined angle.

The catching groove 310 may include a base surface 311 facing the interference portion 210 and/or a catching surface 312 that is bent at the base surface 311 and extends toward the door 20 .

Below, we will look at the process in which opening of the door 20 is interfered with by the door lock 100.

FIG. 16 is a cross-sectional view showing the door 20 and the configuration adjacent to the door 20 of the cooking appliance 1 shown in FIG. 1 cut in cross section.

With reference to FIG. 16, the closed position and interference position of the door 20 will be described.

The door 20 may be located in a closed position where the galley is closed.

When the door 20 is in the closed position, at least a portion of the interference portion 210 of the locker 200 may be received in the catching groove 310. The position of the interference unit 210 at this time may be referred to as the first position. That is, the interference unit 210 may be located at a first position so as to interfere with the opening of the door 20 .

The interference portion 210 may be disposed toward the catching groove 310 through a hole formed on one side of the door 20.

The elastic body 400 may press the pivot portion 220 so that the interference portion 210 receives elastic force from one side of the pivot portion 220 of the locker 200 in a direction toward the control panel 30 .

The door 20 has a limiting part 23 that limits the rotation of the pivot part 220 so that movement in the direction opposite to the second position of the interference part 210 is restricted when the interference part 210 is in the first position. ') may be included.

The door 20 may include a restriction portion 23' to prevent the interference portion 210 from getting closer to the control panel 30 than the first position. When the interference portion 210 is in the first position, the limiting portion 23' may be in contact with the contact portion 223 of the locker 200.

The interference part 210 may not contact the base surface 311 of the catching groove 310 due to the limiting part 23'. Furthermore, movement of the pivot unit 220 may be restricted so that the pivot unit 220 has a fixed position when the interference unit 210 is in the first position. Because of this, when the interference portion 210 is in the first position, the push surfaces 221' and 221' can be stably placed in a position that does not impair the appearance of the door handle 900.

The pivot portion 220 may rotate and move around the rotation shaft 230. The pivot portion 220 may pivot around the rotating shaft 230.

When the interference portion 210 is in the first position and the door 20 is opened from the closed position to the interference position, the step portion 212 of the locker 200 may contact the first engaging surface 312a. Drawings related to this are omitted.

The interference portion 210 of the locker 200 contacts the locking groove 310. More specifically, the step portion 212 of the locker 200 contacts the first locking surface 312a of the locking groove 310. Since the step portion 212 of the locker 200 is not located beyond the end of the first engaging surface 312a, the step portion 212 of the locker 200 cannot be moved forward.

When the locker 200 is located at the first position and the interference portion 210 of the locker 200 is in contact with the guide 300, the door 20 can be said to be located at the interference position.

If the door 20 is in an interfering position, the door 20 may be opened without the galley 41 being opened to the front.

When the door 20 is coupled to one side of the front panel 16 by a hinge 28 to enable pivot movement, the door 20 can be viewed as rotating relative to the hinge 28. When the door 20 is said to rotate, the locker 200 coupled to one side of the door 20 can also be seen to rotate. If the locker 200 rotates, a rotation path of the locker 200 formed by the rotation radius and the rotation radius of the locker 200 may be formed. At this time, the catching surface 312 may be located within the rotation radius of the locker 200. Alternatively, the locking surface 312 may be located within the rotation path of the locker 200.

However, when the door 20 is in an interfering position, the operation of the heating source 51 may not be stopped.

FIG. 17 is a cross-sectional view showing the interference portion 210 of the locker 200 of the cooking appliance 1 shown in FIG. 16 in the second position.

You can move. As a result, the interference unit 210 can be moved to the second position. The interference unit 210 may be moved to a second position arranged to cancel the interference with the opening of the door 20 .

That is, the interference unit 210, which is formed integrally with the pivot unit 220, can move according to the movement of the pivot unit 220. Accordingly, the interference of the interference unit 210 with the guide 300 may be canceled.

When the interference portion 210 is located at the second position, the first engaging surface 312a may not be disposed in front of the step portion 212.

However, even when the interference unit 210 is located in the second position, the elastic body 400 may press the pivot unit 220 to move the interference unit 210 to the first position.

FIG. 18 is a cross-sectional view showing the door 20 of the cooking appliance 1 shown in FIG. 17 in the open position.

Referring to FIG. 18, the case where the door 20 is in the open position will be described.

When the interference unit 210 is moved to the second position, the interference with the opening of the door 20 is released, so the door 20 can move forward.

In other words, when the interference unit 210 is in the first position, the door 20 can be moved from a closed position that closes the cooking compartment to an interference position that interferes with the interference unit 210, and the interference unit 210 When in the second position, it is possible to move from the closed position to an open position spaced further than the interference position.

On the other hand, it can be said that the path along which the open position moves is longer than the path along which the interference position moves, based on the closed position.

The open position of the door 20 can be said to be a position where the front of the galley is completely open to the outside. Only when the door 20 is in the open position can cooking objects placed inside the cooking compartment be taken out or accommodated.

As seen above, depending on the movement of the locker 200, the opening of the door 20 may be interfered with. When the door 20 is in the closed position, the operation of moving the locker 200 from the first position to the second position to open the door 20 may be referred to as the first operation.

After the first operation, the operation of holding the door handle 900 and moving the door 20 to move the door 20 from the closed position to the open position may be referred to as the second operation.

In other words, in order to open the door 20, the user must perform the first operation and/or the second operation. As a result, it is possible to prevent a situation where the user is injured because the galley cannot be easily opened.

FIG. 19 is a cross-sectional view showing the door 20 of the cooking appliance 1 shown in FIG. 17 being moved from the open position to the closed position.

Referring to FIG. 19, it will be explained that the door 20 is moved from the open position to the closed position.

The door 20 may be moved from the open position to the closed position in the reverse order of operation from the closed position to the open position. Therefore, the explanation regarding this is understood as the above operation being carried out in reverse order.

However, the interference portion 210 may include an inclined portion 211 that is pressed and movable while the door 20 moves from the open position to the interference position or the closed position.

While the door 20 moves from the open position to the closed position, the inclined portion 211 may come into contact with the control panel 30. Because the locker 200 is rotatable, as the door 20 moves further to the closed position, the door may move as the locker 200 rotates. When the door 20 moves further to the closed position, the locker 200 can rotate while being prevented from interfering with the control panel 30 by the inclined portion 211.
