With reference to FIGS. 19 and 20 , the interference position and interference cancellation position of the interferer 250 will be described.

Referring to FIG. 19, the interferer 250 may be at an interference position that may interfere with the opening of the door 200. When the interferer 250 is in the interfered position, the door 100 can move from the closed position to the restricted position. When the interferer 250 is at the interference position, at least a portion of the door interference portion 252 of the interferer 250 may be accommodated in the door guide 104. As at least a portion of the door interference portion 252 is received in the door guide 104, the door 100 may interfere with the door lock 240 when moving from the closed position to the open position. When the door 100 moves from the closed position to the open position, the door guide 104 of the door 100 may interfere with the door interference portion 252 of the door lock 240.

Referring to FIG. 20 , the interferer 250 may be in an interference canceling position that prevents the opening of the door 100 from being interfered with. The user can move the interferer 250 to the interference release position by moving the operation unit 258 of the lever 256.

When the interferer 250 is in the disengaged position, the door 100 can move from the closed position to the open position. When the interferer 250 is in the interference release position, the door interference portion 252 of the interferer 250 may be separated from the door guide 104. When the interferer 250 is in the interference release position, the door interferer 252 of the interferer 250 may move inside the lock body 241. As the door interference portion 252 is separated from the door guide 104, the door 100 may not be interfered with by the door lock 240 when moving from the closed position to the open position.

The door interference portion 252 of the interference elastic body 260 may protrude to the outside of the lock body 241 due to the elastic force of the interference elastic body 260.

According to this configuration, the cooking appliance 1 according to one embodiment operates the opening and closing device 120 by moving the button 110, so that even when the door 100 is unlocked, the door lock 240 Since the opening of the door 100 may be restricted, the safety of use may be improved. The cooking appliance 1 according to one embodiment moves the button 110 to operate the opening and closing device 120, thereby unlocking the door 100 and then using the lever 256 of the door lock 240. By moving the manipulation unit 258 to separate the door interference unit 252 of the interferer 250 from the door guide 104, the door 100 can be opened, thereby improving safety of use. Since the door 100 of the cooking appliance 1 according to one embodiment is double locked by the opening and closing device 120 and the door lock 240, the safety of use can be improved.

When the door 100 moves from the open position to the restricted or closed position while the interferer 250 is in the interference position as the force applied to the operating portion 258 of the lever 256 is removed, the door 100 Can move by pushing the door interference portion 252 of the interference body 250 of the door lock 240. When the door 100 moves from the open position to the limited or closed position while the interferer 250 is in the interference position, the door 100 contacts the door guide surface 252b of the door interference portion 252; You can move. When the door 100 moves from the open position to the restricted or closed position while the interferer 250 is in the interference position, the door interferer 252 is pressed by the door 100 and is pressed by the lock body 241. You can move inside. After the door 100 moves from the open position to the restricted or closed position, the interference body 250 may move to the interference position by the elastic force of the interference elastic body 260.

According to this configuration, the cooking appliance 1 according to one embodiment can prevent the movement of the door 100 from being restricted by the door lock 240 while moving from the open position to the restricted or closed position. .

With reference to FIGS. 21 and 22 , the function release position of the interferer 250 of the door lock 240 will be described. The interferer 250 of the door lock 240 may be moved to a function release position where the door interferer 252 is fixed to the inside of the lock body 141 so that it does not protrude to the outside of the lock body 241 .

Referring to FIG. 21, if the user does not want the door 100 to be double locked by the opening/closing device 120 and the door lock 240, the user sets the door lock 240 to disable the function of the door lock 240. It can be manipulated. The user may press the interferer 250 in a direction toward the inside of the lock body 241 using a tool such as a driver. The interferer 250 may further move from the interference release position in the direction opposite to the interference position. The interferer 250 may move from the interference release position to the function release position. While the interferer 250 moves from the interference release position to the function release position, the release interference portion 255 of the interferer 250 may interfere with the release support portion 246 of the lock body 241. While the interferer 250 moves from the interference release position to the function release position, the first interference surface 255a of the release interference portion 255 may contact the first support surface 246a of the release support portion 246. there is. Since the release support portion 246 is provided to be deformable, the release interference portion 255 can move in the direction in which the interference elastic body 260 is contracted while deforming the release support portion 246.

Referring to FIG. 22, when the release interference unit 255 moves until the first interference surface 255a of the release interference unit 255 is released from contact with the first support surface 246a of the release support unit 246. , the deformed release support 246 can be restored to its original state. As the release support part 246 is restored, the second interference surface 255b of the release interference part 255 may contact the second support surface 246b of the release support part 246. The second interference surface 255b of the release interference part 255 may be supported on the second support surface 246b of the release support part 246. The release support part 246 may support the release interference part 255 in a direction opposite to the direction in which the interferer 250 protrudes out of the lock body 241. As the release support portion 246 supports the release interference portion 255, the interferer 250 can maintain the function release position.

When the user wants to use the released function of the door lock 240 again, the user operates the operation unit 258 of the lever 256 of the door lock 240 to move the interferer 250 from the function release position to the interference release position. It can be moved. The user may apply a force to the operation portion 258 of the lever 256 so that a force greater than the force with which the release support portion 246 supports the release interference portion 155 is applied to the interferer 250 . As the user presses the operation unit 258 of the lever 256, the lever 256 moves inside the lock body 241. As the lever 256 moves into the lock body 241, the pull-out pusher 257a presses the pull-out guide 254. Due to the inclined shape of the extraction guide 254, the interferer 250 can be moved to the interference release position. The interferer 250 can be moved by changing the direction of force according to the movement of the lever 256 due to the inclined shape of the withdrawal guide 254.

While the interferer 250 moves from the function release position to the interference release position, the release support 246 may be deformed by the release interferer 255 . When the release interference portion 255 moves until the second interference surface 255b of the release interference portion 255 is released from contact with the second support surface 246b of the release support portion 246, the deformed release support portion ( 246) can be restored to its original state. The interference body 250 can move to the interference position by the elastic force of the interference elastic body 260.

According to this configuration, the cooking appliance 1 can selectively use the function of the door lock 240, so convenience of use can be improved.
