Specifically, in the cooking apparatus, the door 100 and the control panel box 300 are both fixed to the outside of the cabinet 200, the cabinet 200 has a cavity 400 inside corresponding to the door 100, and the door 100 is rotatably connected with the cabinet 200 to open or close the cavity 400. Taking a microwave oven as an example, when the door body 100 is in a closed state, the cavity 400 is closed, and the microwave oven can perform microwave heating on food placed in the cavity 400.

In the present utility model, the switch bracket 2 may be provided on the outer side wall of the chamber 400 inside the case 200, for example; the rotating plate 32 is rotatably connected to the control panel box 300, and is at a static position on the rotating path in a normal state (i.e. the door opening button 31 does not receive an external force). When the door body 100 is closed, the door hook 1 is clamped on the switch bracket 2, and the switch bracket 2 can limit the door hook 1 to move outwards, meanwhile, the telescopic rod 41 correspondingly stretches out, and at least part of the telescopic rod 41 enters the rotating path of the rotating plate 32 so as to be used for blocking the rotating plate 32 to rotate upwards when a child touches the door opening button 31.

Taking a microwave oven as an example, through the door lock structure of the present utility model, the first: when a user opens the microwave oven, the electromagnetic switch 4 needs to be controlled first to enable the telescopic rod 41 to leave the rotating path of the rotating plate 32, then the door opening key 31 is pressed to enable the rotating plate 32 to rotate upwards to push the door hook 1, the door hook 1 moves upwards and is separated from the limitation of the switch bracket 2 when being pushed, and then the clamping state can be released, namely, the user can open the door body 100 after two steps of different simple and convenient operations, thereby effectively preventing children from opening the door by mistake. Second, electromagnetic switch 4 sets up on switch bracket 2, but not set up between rotating plate 32 and the button 31 that opens the door, and then electromagnetic switch 4 can not block the button 31 that opens the door, and the button 31 that opens the door can contact with each position of rotating plate 32, and the button 31 that opens the door of multiple different structures, different positions all can use on this lock structure, can satisfy the design demand of the multiple different outward appearances of button 31 that opens the door, and the commonality is stronger. Thirdly, only the structure of the switch bracket 2 needs to be changed, the electromagnetic switch 4 can be assembled on a common key-type microwave oven, the common microwave oven is changed into a microwave oven with two-step door opening, the universality is strong, parts needing to be changed are fewer, and the mold opening cost of the parts is saved.

Preferably, the switch bracket 2 is disposed adjacent to the door opening assembly 3, and a hanging plate 21 in a clamping fit with the door hook 1 is disposed on the switch bracket 2, and the hanging plate 21 can be used for limiting the outward movement of the door hook 1.

Specifically, the switch bracket 2 may be disposed on the outer side wall of the cavity 400 and adjacent to the control panel box 300, for example, in the interior of the box 200, so that the interaction structure between the door opening button 31, the rotating plate 32, the door hook 1, the hanging plate 21 and the telescopic rod 41 is more compact, that is, the door lock structure of the present utility model is more compact, which is beneficial to improving the operation reliability of the door lock structure itself and optimizing and improving the internal space layout of the box 200 of the cooking apparatus. When the door body 100 is in the closed state, the door hook 1 will be tightly clamped on the hanging plate 21 until the door hook 1 is pressed upwards from the rotating plate 32, and the door hook 1 will not be separated from the limitation of the hanging plate 21 and move outwards to open the door body 100. Corresponding to the rest position, at the unlocking moment, the rotating plate 32 is in the unlocking position on the rotating path, and then when the external force action at the door opening key 31 disappears, the rotating plate 32 automatically returns to the rest position in a normal state along the rotating path.

Preferably, the rotating plate 32 is pivotally connected to the back of the control panel box 300, and a push rod 311 is disposed on the back of the door opening button 31, and the push rod 311 can be used to pass through the control panel box 300 and contact with the rotating plate 32 to push the rotating plate 32 to rotate upwards.

Specifically, for the door body 100, it has three states of to be unlocked, in unlocking, and unlocked, and for both the states to be unlocked and unlocked, the rotating plate 32 can be simply regarded as a static position in a normal state. When the front side of the door opening button 31 is pressed by the user, the push rod 311 will push the rotating plate 32 to rotate upwards, and at this time, according to the telescopic state of the telescopic rod 41, the door body 100 can correspond to three results of successful unlocking (predetermined unlocking procedure), failed unlocking (false child touch), and no need of unlocking again (unlocked).

Preferably, the rotating plate 32 includes a rotating plate body 321 and a rotating shaft 322, the rotating shaft 322 is rotatably inserted into the back surface of the control panel box 300, one end of the rotating plate body 321 is used for abutting against the push rod 311, and the other end is penetrated along one side of the switch bracket 2, and a first pressing block 323 and a second pressing block 324 are formed.

Specifically, in the normal rest position of the rotating plate 32, whether a certain gap is left between one end of the rotating plate body 321 and the push rod 311 or the rotating plate body is directly abutted against the push rod 311 is not particularly limited in the present utility model; at the other end of the rotating plate body 321, the rotating plate body will rotate through the switch bracket 2, and the rotation angle of the first pressing block 323 and the second pressing block 324 in the switch bracket 2 will also change along with the upward rotation of the rotating plate body 321.

Preferably, the first pressing block 323 is located above the second pressing block 324, and the first pressing block 323 rotates upward with the rotating plate 32 to press the door hook 1 to be separated from the switch bracket 2.

As a preferred embodiment of the present utility model, the door lock structure further includes a micro switch 5 disposed on the switch bracket 2, and the second pressing block 324 is pressed against or separated from the micro switch 5 below the second pressing block, so that the micro switch 5 is used for feeding back the locking state of the door lock structure in real time, wherein the micro switch 5 is further in communication connection with the telescopic rod 41, so as to synchronously trigger the corresponding extension of the telescopic rod 41 when the door body 100 triggers the closed state.

Specifically, the first pressing block 323 may be rotatably disposed below the door hook 1 (hanging plate 21), and the second pressing block 324 may be rotatably disposed above the micro switch 5. When the door body 100 triggers the closed state, the door hook 1 is tightly clamped with the hanging plate 21 and contacts the first pressing block 323 downward, so that the second pressing block 324 contacts the micro switch 5 downward, and then the telescopic rod 41 correspondingly extends out and stops on the upward rotation path of the second pressing block 324. Conversely, when the door body 100 triggers the open state, the second pressing block 324 may be separated from the micro switch 5 upwards to release the contact pressure of the micro switch 5. Thus, the micro switch 5 can be used for feeding back the locking state of the door lock structure in real time.

As a preferred example of the present utility model, the first pressing block 323 and the second pressing block 324 form an angle of 90 degrees therebetween, so that the telescopic rod 41 can easily avoid the first pressing block 323 and stop on the upward rotation path of the second pressing block 324 precisely when correspondingly extending.

Further, the switch bracket 2, the hanging plate 21, the micro switch 5 and the electromagnetic switch 4 arranged on the switch bracket can be surrounded to form a movement space 22, and the door hook 1 can be clamped downwards or separated upwards from the movement space 22; regardless of whether the rotating plate 32 is in the rest position or the unlocking position on the rotating path, the first pressing block 323 and the second pressing block 324 are only rotated in the movement space 22; and the telescopic rod 41 is also extended forward into or backward out of the movement space 22.

Further, the electromagnetic switch 4 is fastened and fixed on the first mounting part of the switch bracket 2 through a fastener 6; of course, the micro-switch 5 may be fastened to the second mounting portion of the switch bracket 2 by a fastener 6. Meanwhile, two door hooks 1 distributed up and down can be arranged on the door body 100, and two micro switches 5 distributed up and down along with the door hooks 1 can be arranged on the single switch bracket 2, but only one electromagnetic switch 4 and one door opening assembly 3 are needed, and the two electromagnetic switches and the door opening assemblies are corresponding to the door hooks 1 distributed below. Of course, even on only a single switch bracket 2, the hanging plate 21 will have two vertically distributed hooks 1.

Preferably, the electromagnetic switch 4 is disposed adjacent to the rotating plate 32, and the telescopic rod 41 is located on the rotating path of the second pressing block 324 in the extended state and is separated from the rotating path of the second pressing block 324 in the retracted state.

Specifically, in a normal door opening procedure, after a user operates, the telescopic rod 41 is retracted, so that the door body 100 is normally opened according to a predetermined procedure; in the false touch procedure of the child side-by-side door button 31, the telescopic rod 41 will interfere with the second pressing block 324 due to the extended state, so that the rotating plate 32 cannot continue to rotate upwards, and the door hook 1 cannot move upwards to a position capable of being separated from the hanging plate 21, that is, the first pressing block 323 cannot press the door hook 1 to be separated from the switch bracket 2; in addition, when the microswitch 5 triggers the locked state of the door lock structure, the telescopic rod 41 in the original retracted state will correspondingly automatically extend and stop on the upward rotation path of the second pressing block 324.
