The present application is illustrated by taking the cooking apparatus 200 as a microwave oven. The cooking apparatus 200 includes a case 201 and a door 202, the door 202 is openably and closably provided at the case 201, and further, the case 201 defines a storage space with one end opened, for example: the case 201 defines a storage space with an open front end, in which an object is adapted to be placed for heating, and the door 202 may open or close the open end of the storage space. The present application is illustrated with respect to a cooking apparatus 200 as an example of the placement orientation of fig. 1.

As shown in fig. 1 to 21, a door lock structure 100 according to an embodiment of the present application includes: the operating member 10, the clamping member 20, the rotating member 30 and the limiting assembly 50. The operation element 10 is movably disposed on the door body 202, a portion of the operation element 10 is exposed on the door body 202, that is, the operation element 10 is disposed on the door body 202, and the operation element 10 is movable relative to the door body 202, a portion of the structure of the operation element 10 is exposed on the door body 202, and another portion of the structure of the operation element 10 is disposed in the door body 202. The clamping piece 20 is movably arranged on the door body 202, the clamping piece 20 comprises a door hook 21, the door hook 21 is suitable for being matched with or separated from a limiting part 301 of the box body 201, when the limiting part 301 of the box body 201 of the door hook 21 is matched, the door body 202 closes the open end of the storage space, and when the limiting part 301 of the box body 201 is separated, the door body 202 opens the open end of the storage space, namely, the door body 202 is opened.

The rotating member 30 is rotatably disposed on the door 202 between the locking position and the unlocking position, and it is also understood that the rotating member 30 is rotatably disposed on the door 202, and the rotating member 30 rotates between the locking position and the unlocking position, and the rotating member 30 has opposite first and second ends, and when the rotating member 30 is disposed in the direction of fig. 11, the first end of the rotating member 30 is an upper end of the rotating member 30, and the second end of the rotating member 30 is a lower end of the rotating member 30. When the rotating member 30 is in the locking position, the door hook 21 is matched with the limiting portion 301 of the box 201, the door 202 is closed, and when the rotating member 30 is in the unlocking position, the clamping member 20 is unlocked, and the door hook 21 is suitable for being separated from the limiting portion 301 of the box 201, so that the door 202 is opened.

As shown in fig. 1, 5 and 11, when the door 202 is locked, the limiting assembly 50 is in an avoidance state, the door hook 21 is suitable for being matched with the limiting portion 301 of the box 201, the rotating member 30 is located at the locking position, the lower end of the rotating member 30 is in abutment with the clamping member 20, the rotating member 30 limits the upward movement of the clamping member 20, that is, the clamping member 20 cannot move upward, so that the clamping hook 516 is in clamping fit with the limiting portion 301, the door 202 is locked on the box 201, and the child locking function is realized. When the door 202 needs to be unlocked and opened, as shown in fig. 7 and 9, the operating member 10 is controlled to push the rotating member 30 to rotate from the locking position towards the unlocking position, so that the rotating member 30 rotates to the unlocking position, the rotating member 30 avoids the release of the clamping member 20, a user pulls the door 202, under the cooperation of the first guide inclined plane and the second guide inclined plane, in the opening process of the door 202, the clamping member 20 moves upwards relative to the door 202, and the clamping hook 516 is separated from the limiting part 301 of the box 201, so that the door 202 is opened, the operating member 10 can be released after the door 202 is opened, meanwhile, in the opening process, the clamping member 20 moves towards the limiting assembly 50 to push the limiting assembly 50 to switch from the release state to the limiting state, so that the limiting assembly 50 contacts and limits the rotating member 30, the limiting assembly 50 can limit the rotating member 30 to rotate towards the locking position, the rotating member 30 is kept at the unlocking position, the lock is kept unlocked along with the opening operation, and the unlocking is kept. When the door 202 needs to be closed, the operating member 10 does not need to be controlled again to push the rotating member 30 to rotate toward the unlocking position. In the process of closing the door body 202, after the clamping hook 516 contacts with the limiting part 301, under the action of the limiting part 301, the clamping piece 20 is lifted to move upwards, then the clamping hook 516 and the limiting part 301 are clamped together, meanwhile, in the process of lifting up and moving the clamping piece 20 upwards, the clamping piece 20 pushes the limiting assembly 50 to enable the limiting assembly 50 to be switched from a limiting state to an avoiding state, under the action of the first resetting piece 40, the first resetting piece 40 drives the rotating piece 30 to rotate to a locking position, the lower end of the rotating piece 30 is enabled to be abutted against the clamping piece 20, when the clamping piece 20 moves to a lower limit position, the door body 202 is tightly closed, the door body 202 is automatically locked along with the closing operation, the limiting assembly 50 is located in the avoiding state, and the effect that the door body 202 can be normally closed without controlling the operating piece 10 again after the door body 202 is opened is achieved.

Specifically, as shown in fig. 21, the limiting portion 301 is provided with a receiving space and a blocking piece, and the blocking piece includes a second guiding inclined surface inclined toward the close hook 516. In the process of matching the hook 516 with the limiting part 301, the hook 516 moves towards the accommodating space along the second guiding inclined plane of the baffle plate, and when the hook 516 moves beyond the second guiding inclined plane to approach the end of the accommodating space, the hook 516 falls into the accommodating space, so that the hook 516 hooks on the baffle plate, and the matching of the hook 516 and the limiting part 301 is realized.
