[0024] The technical solution of the present utility model will be further described below with reference to embodiments and the accompanying drawings.

[0025] Example 1 Refer to Figures 1 to 8 , the present utility model discloses a door lock structure, comprising a first locking member, a second locking member and a driving assembly 4, wherein the first locking member is clamped with the second locking member, and the driving assembly 4 is connected with the second locking member. In use, the driving assembly 4 drives the second locking member to move away from the first locking member, so that the second locking member is separated from the first locking member.

[0026] Specifically, one end of the first locking member is provided with a first locking portion 1, which is clamped with the second locking member.

[0027] An end of the second locking member away from the driving assembly 4 is provided with a second locking portion 2, and the other end is connected to the driving assembly 4, so that the driving assembly 4 can drive the second locking portion 2 to rotate and connect with the first locking portion 1. In addition, an elastic member 3 is further provided on the second locking member, and the elastic member 3 is elastically connected to the bottom of the second locking portion 2, which can push the second locking portion 2 to rotate in a first direction in use.

[0028] The driving assembly 4 comprises a motor 41, a linking member 42 and a guide arm 43. A rotating shaft is provided on the outer surface of the motor 41, and the rotating shaft penetrates through the middle part of the linking member 42, so that the motor 41 can drive the linking member 42 to rotate in a second direction through the rotating shaft. A linking portion 421 is provided on the linking member 42, and the guide arm 43 comprises a first end 431 and a second end 432 connected to each other. When the linking member 42 rotates, the linking portion 421 drives the first end 431 to connect with or separate from the linking member 42, and the second end 432 is connected with the second locking portion 2, so that the linking portion 421 can drive the second locking portion 2 to rotate in the second direction, and finally make it move away from the first locking member, and drive the door body 7 to open.

[0029] It should be noted that in this embodiment, based on the perspective of Figure 1 , the first direction is a counterclockwise direction and the second direction is a clockwise direction.

[0030] It should also be noted that the door lock structure of the present application is suitable for structures with openable and closable door panels such as cooking devices, and can be used to connect and lock the door body 7 and a cooking body 8.

[0031] Based on the above structure, when assembling the door lock structure, first install the end of the first locking member away from the first locking part 1 onto the door body 7, and then install the second locking member and the drive assembly 4 inside the cooking unit 8. In this way, as the second locking part 2 rotates, the first locking part 1 will move away from or closer to the second locking part 2, thereby unlocking or locking the door body 7. Therefore, the drive assembly 4 can control the unlocking or locking of the door body 7 by driving the second locking member away from or closer to the first locking member. The assembly process is as follows: first, install the motor 41 inside the cooking unit 8, install the linkage 42 on its surface at the pivot, connect the second end 432 of the guide arm 43 and the second locking part 2, then install both inside the cooking unit 8, and connect the first end 431 of the guide arm 43 to the linkage 42. Finally, align the first locking part 1 with the second locking part 2 and push the door body 7, thereby installing and locking the door body 7 onto the cooking unit 8. The assembly process is brief.

[0032] When using the door lock structure, to unlock the door, the motor 41 is started, causing the shaft to rotate and drive the linkage 42 connected to it to rotate in the second direction. After the linkage 42 rotates in the second direction, the linkage part 421 on it can press against the first end 431 of the guide arm 43. After the first end 431 of the guide arm 43 is pressed by the linkage part 421, it rotates in the second direction. The second locking part 2 connected to the second end 432 of the guide arm 43 also rotates in the second direction. In this way, the second locking part 2 of the second locking member will separate from the first locking part 1 of the first locking member, thereby unlocking the door 7.

[0033] At the same time, as the second locking part 2 rotates in the second direction, the elastic element 3 is compressed by the second locking element. After the door 7 is unlocked, the elastic element 3 rebounds and pushes the second locking part 2 back to its original position in the first direction. The aforementioned linkage 42 can continue to rotate in the second direction under the action of the motor 41, so that the linkage part 421 of the linkage 42 disengages from the first end 431 of the guide arm 43. The linkage part 421 also disengages from the first end 431 and rotates back to its original position, preparing for the next unlocking.

[0034] During the above process, the power of the motor 41 is transmitted to the second locking part 2 through the linkage 42 and the guide arm 43. The power transmission process is short and direct, thereby reducing power loss and ensuring high stability of power transmission and structural operation.

[0035] When locking is required, push the door 7. The first locking part 1 and the second locking part 2 abut and slide. The second locking part 2 is pressed in the second direction by the first locking part 1, which causes the elastic element 3 to be compressed. After the first locking part 1 and the second locking part 2 are engaged, the elastic element 3 will rebound and push the second locking part 2 in the first direction to strengthen its engagement effect with the first locking part 1. The steps are simple.

[0036] Compared to existing technologies, the door lock structure of cooking appliances is typically a gear and linkage structure, with multiple linkages interconnected and multiple gears meshing. One end of the guide rod is connected to one of the gears, and the other end is connected to one of the linkages. The last linkage is connected to the door body 7. A motor 41 drives multiple gears to rotate, which in turn drives the guide rod, thereby driving multiple linkages to move sequentially and pushing the door body 7 outward to unlock. However, this structure requires power to be transmitted between multiple parts, resulting in a lengthy power transmission process, increased power loss, and weak structural stability.

[0037] Therefore, in this embodiment, only a motor 41, a linkage 42, a guide arm 43, and a second locking element are used to control the unlocking of the door lock. The power transmission process is simply: motor 41 and linkage 42, linkage 42 and guide arm 43, and guide arm 43 and second locking element. The power transmission process is short and the power loss is small, so the power transmission and structural stability are strong.

[0038] Furthermore, the first locking part 1 is provided with a first locking hook 11, and the second locking part 2 is provided with a corresponding second locking hook 21.

[0039] It should be noted that the first locking hook 11 and the second locking hook 21 can also be configured as a first magnetic strip and a second magnetic strip, which are connected by magnetism. When the second end 432 of the guide arm 43 drives the second locking part 2 to rotate in the second direction, the second magnetic strip is continuously subjected to force until the pushing force is greater than the magnetic force, at which point the second magnetic strip moves away from the first magnetic strip, thus unlocking. The specific structural configuration of the first locking hook 11 and the second locking hook 21 can be selected according to actual needs.

[0040] Specifically, the first locking hook 11 has a locking protrusion 111 at one end near the second locking hook 21, and the second locking hook 21 has a locking groove 211 at one end near the first locking hook 11. The locking protrusion 111 engages with the locking groove 211.

[0041] More specifically, the locking groove 211 is provided with a first abutting surface 1111 and a first limiting surface 1112, and correspondingly, the locking protrusion 111 is provided with a second abutting surface 2111 and a second limiting surface 2112.

[0042] When in use, when unlocking is required, motor 41 drives guide arm 43, guide arm 43 drives second locking part 2 to rotate in the second direction, second locking part 2 drives second locking hook 21 to rotate, locking groove 211 rotates accordingly, so that locking groove 211 moves away from locking protrusion 111. At the same time, elastic member 3 is compressed by second locking hook 21, and first abutting surface 1111 separates from second abutting surface 2111, first limiting surface 1112 separates from second limiting surface 2112, so that second locking part 2 separates from first locking part 1, realizing unlocking of door 7. The power transmission process is short, power loss is reduced, and structural stability is strong.

[0043] When locking is required, the first locking part 1 is pushed by the door body 7 towards the second locking part 2. The first locking part 1 drives the first locking hook 11 to move. The first locking hook 11 abuts and slides with the second locking hook 21, so that the second locking hook 21 is pressed down. The elastic member 3 is compressed accordingly. The locking protrusion 111 is driven by the first locking hook 11 towards the locking groove 211. After the locking protrusion 111 and the locking groove 211 are engaged, the elastic member 3 rebounds and pushes the locking groove 211 along the first direction to strengthen its engagement effect with the locking protrusion 111. At this time, the first abutting surface 1111 abuts with the second abutting surface 2111, and the first limiting surface 1112 abuts with the second limiting surface 2112. The door body 7 is locked and easy to operate.

[0044] In addition, a limiting post 212 is provided at the bottom of the second locking hook 21. The limiting post 212 is connected to the elastic element 3, which is specifically a spring. The limiting post 212 is inserted into the space in the middle of the spring to limit the movement trajectory of the elastic element 3 to up and down. This prevents the elastic element 3 from accidentally moving to the left and right during use and becoming disengaged from the second locking hook 21, which would prevent the second locking hook 21 from being pushed in the first direction during use, thus affecting the unlocking and locking effect of the door lock structure.

[0045] Since the linkage 42 is engaged with the first end 431 of the guide arm 43 to connect or move away, when the linkage 42 is driven by the rotating shaft driven by the motor 41, the linkage part 421 on the linkage 42 repeatedly performs two work processes from connecting with the first end 431 to moving away from the first end 431. When connected with the first end 431, it can press the first end 431 to rotate, thereby unlocking.

[0046] In this way, when unlocking is required, motor 41 starts, driving linkage 42 to rotate in the second direction. Linkage part 421 on linkage 42 rotates accordingly. Only when linkage part 421 presses against the first end 431 can it drive guide arm 43 to rotate in the second direction. This causes the second locking part 2 to be moved away from the first locking part 1 by guide arm 43, thus unlocking. During this process, elastic element 3 is compressed. After unlocking, elastic element 3 rebounds, pushing the second locking part 2 to move in the first direction. Guide arm 43 is driven back to its original position, and motor 41 drives linkage 42 to rotate in the second direction, causing linkage part 421 to move away from the first end 431 and return to its original position, preparing for the next unlocking. Therefore, motor 41 and linkage 42 do not need to rotate a full circle to achieve unlocking, resulting in a fast unlocking speed.

[0047] Since the linkage 42 is a cam, the cam can be divided into an arc segment 422 and an inclined segment 423 according to its structural shape. The linkage part 421 is set on the arc segment 422. The outline of the arc segment 422 is an arc shape, and the outline of the inclined segment 423 is two symmetrical inclined surfaces. The size of the inclined segment 423 is smaller than that of the arc segment 422. Therefore, when unlocking is required, the cam rotates. When the inclined section 423 approaches the first end 431, it will avoid the first end 431 and will not connect with it. When the arc section 422 approaches the first end 431, the linkage part 421 on it will press against the first end 431 to make it rotate, thereby unlocking. After unlocking, the elastic element 3 rebounds, and the guide arm 43 is driven to rotate back to its original position along the first direction. The motor 41 drives the linkage part 42 to continue rotating in the second direction, causing the linkage part 421 on the arc section 422 to move away from the first end 431 and rotate back to its original position. Therefore, the motor 41 and the linkage part 42 only need to rotate a small section to achieve quick unlocking without needing to rotate a full circle.

[0048] In this embodiment, unlocking is achieved by the arc segment 422 of the cam pressing against the first end 431. During the pressing action, the arc segment 422 contacts the first end 431 when the arc is tangent to it. As the arc segment 422 rotates, the tangent point changes continuously. Therefore, after the arc segment 422 completes the pressing and unlocking action with the first end 431, it can disengage from the first end 431 in time when it continues to rotate, thus achieving rapid unlocking.

[0049] It should be noted that the linkage 42 can also be an eccentric shaft, whose rotation trajectory is similar to that of a cam. When unlocking is required, the motor 41 drives the eccentric shaft to rotate. When it is connected to the first end 431, it can drive the second end 432 to rotate in the second direction, thereby moving the second locking hook 21 away from the first locking hook 11 and achieving unlocking. The specific structure of the linkage 42 can be selected according to actual needs.

[0050] Furthermore, the door lock structure also includes a micro switch 5, which is electrically connected to the motor 41. A touch panel 22 is provided at the bottom of the second locking part 2, which is used to connect to the micro switch 5.

[0051] When unlocking is required, motor 41 starts, driving the second locking part 2 away from the first locking part 1 to achieve unlocking. At the same time, the touch panel 22 is driven by the second locking part 2 to press the micro switch 5, and the micro switch 5 sends a stop signal to motor 41 to stop it.

[0052] During the unlocking process described above, the elastic element 3 is compressed. After unlocking, the elastic element 3 rebounds, pushing the second locking part 2 to rotate in the first direction. The touch panel 22 then moves away from the micro switch 5, and the motor 41 starts, causing the linkage 42 to continue rotating in the second direction and return to its original position, preparing for the next rotation unlock. Therefore, the micro switch 5 can control the motor 41 to stop.

[0053] In addition, the door lock structure also includes a mounting base 6, which has a mounting cavity inside, and the first locking element, the second locking element, the drive assembly 4 and the micro switch 5 are all integrated in the mounting cavity.

[0054] This design prevents individual components from shifting due to interference from other components, which could lead to poor locking and unlocking performance. It also enhances structural stability and allows for easy removal of the mounting base 6 when maintenance or replacement is needed.

[0055] Furthermore, a reset plate 61 is provided above the second locking part 2 on the mounting base 6. When the door lock structure needs to be locked, the second locking part 2 is pushed by the first locking part 1 to rotate in the second direction, and the elastic member 3 is also compressed until the first locking hook 11 and the second locking hook 21 are engaged. At this time, the elastic member 3 rebounds and continues to push the second locking part 2 until the second locking part 2 abuts against the reset plate 61. Therefore, the reset plate 61 can prevent the second locking part 2 from rotating excessively in the first direction, so as not to affect the locking effect of the first locking part 1 and the second locking part 2, and enhance the structural stability.

[0056] Example 2 See Figures 1 to 8 This utility model discloses a cooking device, including a cooking body 8, a door 7, and a door lock structure of embodiment 1. The end of the first locking member away from the first locking hook 11 is connected to the door 7. The mounting base 6 is disposed on the cooking body 8. In addition to the door lock structure, there are other movable connecting devices between the door 7 and the cooking body 8 that do not have a locking function. During assembly, the movable connecting devices pre-connect the door 7 and the cooking body 8, and then the structure of the mounting base 6 other than the first locking hook 11 is installed on the cooking body 8. The first locking hook 11 is installed on the door 7, and the first locking hook 11 and the second locking hook 21 are aligned and engaged to lock the door 7 and the cooking body 8. The assembly is convenient.

[0057] When using the door lock structure, to unlock the door, the motor 41 is started, causing the shaft to rotate and drive the linkage 42 connected to it to rotate in the second direction. After the linkage 42 rotates in the second direction, the linkage part 421 on it can press against the first end 431 of the guide arm 43. After the first end 431 of the guide arm 43 is pressed by the linkage part 421, it rotates in the second direction. The second locking part 2 connected to the second end 432 of the guide arm 43 also rotates in the second direction. In this way, the second locking part 2 of the second locking member will separate from the first locking part 1 of the first locking member, thereby unlocking the door 7.

[0058] At the same time, as the second locking part 2 rotates in the second direction, the elastic element 3 is compressed by the second locking element. After the door 7 is unlocked, the elastic element 3 rebounds and pushes the second locking part 2 back to its original position in the first direction. The aforementioned linkage 42 can continue to rotate in the second direction under the action of the motor 41, so that the linkage part 421 of the linkage 42 disengages from the first end 431 of the guide arm 43. The linkage part 421 also disengages from the first end 431 and rotates back to its original position, preparing for the next unlocking.

[0059] When locking is required, push the door 7. The first locking part 1 and the second locking part 2 abut and slide. The second locking part 2 is pressed in the second direction by the first locking part 1, which causes the elastic element 3 to be compressed. After the first locking part 1 and the second locking part 2 are engaged, the elastic element 3 will rebound and push the second locking part 2 in the first direction to strengthen its engagement effect with the first locking part 1. The steps are simple.

[0060] The other aspects of the door lock structure are the same as in Embodiment 1, and will not be repeated here.

[0061] It should be noted that the cooking device in this application can be an oven, microwave oven, or microwave-steam-grill combination appliance, as is available in the prior art. After the door panel is unlocked, it can maintain its connection with the cooking body 8 through the movable connecting device. The door 7 can be opened by rotating or pushing. When locking, simply turning or pushing back will allow the first and second locking parts to accurately engage without the need for re-alignment and re-engaging, making it convenient and quick.

[0062] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
