Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and more specifically, to a cooking appliance. Background Technology

[0002] Currently, during or after cooking, a high-temperature environment is formed inside the cooking cavity of cooking appliances. If the user accidentally touches the door to open the cooking appliance, it can easily cause injury to the user. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] Therefore, the present invention provides a cooking utensil.

[0005] In view of this, the present invention provides a cooking appliance, comprising: a cooking body; a door movably connected to the cooking body to open or close the cooking body; and a door lock assembly including an unlocking part, a first locking part, and a second locking part, wherein the first locking part is disposed on the door, the second locking part is disposed on the cooking body, the unlocking part is movably disposed on the cooking body and corresponding to the second locking part, and the unlocking part is capable of pushing at least a portion of the second locking part to switch between a locked state and an unlocked state; in the locked state, the door and the cooking body are locked; and in the unlocked state, the door is capable of opening the cooking body.

[0006] The cooking appliance provided by this invention includes a cooking body, a door, and a door lock assembly. The door can open or close the cooking body. The door lock assembly includes an unlocking part, a first locking part, and a second locking part. The first locking part is disposed on the door, and the second locking part is disposed on the cooking body. The first and second locking parts have unlocked and locked states. When the first and second locking parts are locked, pulling the door cannot open the cooking body, thus improving the safety performance of the cooking appliance. When the first and second locking parts are unlocked, pulling the door can open the cooking body. The unlocking part is disposed on the cooking body, corresponding to the cooking body, and can move relative to the cooking body. During the movement of the unlocking part relative to the cooking body, it can drive at least a portion of the second locking part to move, allowing the second locking part and the first locking part to switch between unlocked and locked states to unlock or lock the cooking appliance. Furthermore, with the unlocking part on the cooking body, the user can unlock the appliance by first operating the unlocking part on the cooking body and then pulling the door, completing a two-step opening process. This design is simple, low-cost, convenient, quick, and highly reliable.

[0007] The cooking appliance provided by the present invention may also have the following additional technical features:

[0008] In some possible designs, the second locking part includes: a bracket disposed on the cooking body, the bracket having a limiting part; a locking structure movably connected to the limiting part, an unlocking part corresponding to the locking structure, the unlocking part being able to push the locking structure to move so that the locking structure and the limiting part switch between limiting engagement and unlocking; when the limiting engagement is in the case of engagement, the first locking part and the locking structure are in a locked state, and when the limiting is unlocked, the first locking part and the locking structure are in an unlocked state.

[0009] In this design, the second locking part includes a bracket and a locking structure. The bracket is mounted on the cooking body, and the locking structure is movably mounted on the limiting part of the bracket. An unlocking part is correspondingly positioned to the locking structure. The user can move the locking structure by operating the unlocking part, allowing the locking structure to engage or disengage with the limiting part. When the locking structure and the limiting part are engaged, they are locked, and the first locking part and the locking structure are locked, preventing the cooking body from opening by pulling the door. When the locking structure and the limiting part are disengaged, the locking structure can move relative to the limiting part, allowing the first locking part and the locking structure to unlock, and the cooking body can be opened by pulling the door.

[0010] In some possible designs, when the locking structure and the limiting part are released from their limiting positions, the first locking part can drive the locking structure to rotate relative to the limiting part, so as to separate the first locking part from the locking structure or to lock the first locking part with the locking structure.

[0011] In this design, when the locking structure and the limiting part are released, the first locking part drives the locking structure to rotate relative to the limiting part, causing the locking structure to move to a position where it can separate from the first locking part, thereby opening the cooking body; alternatively, the first locking part can also drive the locking structure to rotate relative to the limiting part, causing the locking structure to move back to a state where it can engage with the limiting part, and then the first locking part and the limiting structure lock together after the limiting part and the locking structure are engaged. That is, when the unlocking part pushes the locking structure to move, causing the locking structure to release from the limiting part, the locking structure can rotate relative to the limiting part. At this time, pulling the door causes the first locking part on the door to move with the door, causing the first locking part to drive the locking structure to rotate until the first locking part and the locking structure separate, thereby opening the cooking body; when closing the door, pushing the door towards the cooking body causes the door to move the first locking part closer to the locking structure, and the first locking part pushes the locking structure to move to a position where it can engage with the limiting part, and the first locking part and the locking structure return to the locked state.

[0012] In some possible designs, the limiting part includes a rotating shaft and a limiting block disposed on the side wall of the rotating shaft; the locking structure is provided with a shaft hole and a limiting hole extending radially from the shaft hole, and the rotating shaft is disposed in the shaft hole; when the limiting engagement is performed, the limiting block is disposed in the limiting hole, and the unlocking part can push the locking structure to move along the axial direction of the rotating shaft so that the limiting block is released from the limiting hole; when the limiting engagement is released, the limiting block is separated from the limiting hole, and the first locking part can drive the locking structure to rotate so that the limiting block is misaligned or corresponds to the limiting hole.

[0013] In this design, the limiting part includes a rotating shaft and a limiting block, with the limiting block disposed on the side wall of the rotating shaft. The locking structure has a shaft hole and a limiting hole, with the limiting hole disposed on the side wall of the shaft hole and extending radially along the shaft hole. The rotating shaft is disposed within the shaft hole. The engagement and disengagement of the limiting block and the limiting hole achieve the limiting engagement or disengagement of the locking structure and the limiting part. When the limiting block is located within the limiting hole, the limiting block restricts the circumferential rotation of the locking structure along the rotating shaft, placing the locking structure and the limiting part in a limiting engagement state, thus locking the door to the cooking body. In this state, the unlocking part can drive the locking structure to move, causing the limiting block to separate from the limiting hole, thereby releasing the limiting part from the locking structure. When the limiting part and the locking structure are released, the first locking part can drive the locking structure to rotate, causing the limiting block to misalign or correspond with the limiting hole.

[0014] In some possible designs, the door lock assembly also includes: a reset member, located between the side of the locking structure away from the unlocking part and the bracket; when the limiting hole rotates to the position corresponding to the limiting block, the reset member pushes the locking structure to reset so that the limiting block and the limiting hole are in a limiting engagement.

[0015] In this design, the cooking appliance also includes a reset component, which is located between the side of the locking structure away from the unlocking part and the bracket. The reset component is used to reset the locking structure, thereby allowing the limiting block to engage with the limiting hole.

[0016] In some possible designs, the locking structure is provided with a hook groove. Along the rotation direction of the locking structure, the hook groove includes a first wall and a second wall that are arranged opposite to each other, and the first wall and the second wall surround the groove opening. The first locking part includes a door hook that extends into or out of the hook groove through the groove opening. The door hook can drive the locking structure to rotate through the first wall or the second wall.

[0017] In this design, the locking structure is provided with a hook groove, and the first locking part includes a door hook that can cooperate with the hook groove. The hook groove includes a first wall surface and a second wall surface arranged opposite each other, and a slot formed by the first wall surface and the second wall surface. The door hook extends into the hook groove through the slot to be limited in position with the hook groove, or moves out of the slot to be separated from the hook groove. Specifically, the door hook pushes the locking structure to rotate through the first wall surface or the second wall surface, thereby achieving the limitation or separation of the door hook from the hook groove.

[0018] In some possible designs, the bracket is provided with an opening through which the door hook extends into or moves out of the hook groove; when the limit is released, the door hook can pull the hook groove to make the groove align with the opening.

[0019] In this design, the bracket is provided with an opening, through which the door hook extends into or moves out of the hook groove. When the limiting block and the limiting hole are released, the door hook can drive the locking structure to rotate, so that the groove and the opening correspond, and then the door hook can move out from the groove and the opening, so that the door hook is separated from the second locking part, thereby realizing the opening of the cooking body.

[0020] Correspondingly, when the door is closed, the door hook can also extend into the slot through the opening, thereby driving the locking structure to rotate, so that the locking structure and the limiting part are in a limiting engagement.

[0021] In some possible designs, the door lock assembly also includes a torsion spring, which is connected to the locking structure and bracket, and is in a deformed state in both the locked and unlocked states.

[0022] In this design, the cooking appliance also includes a torsion spring, which is connected to the support and locking structure to ensure stable movement of the locking structure.

[0023] In some possible designs, the unlocking mechanism is located on the side wall of the cooking body.

[0024] In this design, the unlocking mechanism is located on the side wall of the cooking unit for easy user operation.

[0025] In some possible designs, the cooking body includes: a shell, the shell including a cooking cavity, and a second locking part disposed on the outer side wall of the shell; and an outer cover disposed on the outer side wall of the shell, with an unlocking part disposed on the outer cover.

[0026] In this design, the cooking body includes a shell and an outer cover. The shell includes a cooking cavity, and a door is used to open or close the cooking cavity. The outer cover is located on the outer wall of the shell, a second locking part is located on the outer wall of the shell, and an unlocking part is located on the outer cover and is correspondingly arranged with the second locking part. Thus, by operating the unlocking part, the second locking part can be unlocked from the first locking part.

[0027] In some possible designs, the outer cover is provided with mounting holes, which correspond to the second locking part; the unlocking part includes a button and a button slot, with the button slot located inside the mounting hole and the button slidingly located in the button slot.

[0028] In this design, the unlocking part includes a button and a button slot. The outer cover is provided with a mounting hole, the button slot is disposed in the mounting hole, and the button is disposed in the button slot. The button can slide relative to the button slot, thereby driving the second locking part.

[0044] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0045] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0046] The following reference Figures 1 to 11 A cooking appliance is described according to some embodiments of the present invention.

[0047] like Figure 1 and Figure 2 As shown, according to one embodiment of the present invention, the present invention provides a cooking appliance, including: a cooking body 1, a door 2, and a door lock assembly 3.

[0048] Specifically, the door 2 is movably connected to the cooking body 1 to open or close the cooking body 1; the door lock assembly 3 includes an unlocking part 30, a first locking part 31, and a second locking part 32. The first locking part 31 is disposed on the door 2, the second locking part 32 is disposed on the cooking body 1, the unlocking part 30 is movably disposed on the cooking body 1 and is disposed corresponding to the second locking part 32, and the unlocking part 30 can push at least a portion of the movement of the second locking part 32 to switch the second locking part 32 and the first locking part 31 between a locked state and an unlocked state; in the locked state, the door 2 and the cooking body 1 are locked; in the unlocked state, the door 2 can open the cooking body 1.

[0049] The cooking appliance provided by this invention includes a cooking body 1, a door 2, and a door lock assembly 3. The door 2 can open or close the cooking body 1. The door lock assembly 3 includes an unlocking part 30, a first locking part 31, and a second locking part 32. The first locking part 31 is disposed on the door 2, and the second locking part 32 is disposed on the cooking body 1. The first locking part 31 and the second locking part 32 have an unlocked state and a locked state. When the first locking part 31 and the second locking part 32 are in the locked state, pulling the door 2 cannot open the cooking body 1, thereby improving the safety performance of the cooking appliance. When the first locking part 31 and the second locking part 32 are in the unlocked state, pulling the door 2 can open the cooking body 1. The unlocking part 30 is disposed on the cooking body 1, corresponding to the cooking body 1 and movable relative to the cooking body 1. During the movement of the unlocking part 30 relative to the cooking body 1, it drives at least a portion of the movement of the second locking part 32, allowing the second locking part 32 and the first locking part 31 to switch between unlocked and locked states, thereby unlocking or locking the cooking appliance. Furthermore, with the unlocking part 30 on the cooking body 1, the user can unlock the appliance by first operating the unlocking part 30 on the cooking body 1 and then pulling the door 2, completing a two-step opening process. This design is simple, low-cost, convenient, quick, and highly reliable.

[0050] It is understandable that the cooking body 1 is provided with a cooking cavity 102, and the door 2 is used to close the cooking cavity 102 so as to realize the cooking of the ingredients in the cooking cavity 102.

[0051] In practical applications, the unlocking part 30 is located on the side of the cooking body 1. A handle is provided on the door 2. Furthermore, when the first locking part 31 and the second locking part 32 are unlocked, the door 2 rotates downwards to open the cooking body 1; that is, the cooking appliance is a pull-down door type. Of course, the cooking appliance can also be a side-opening door type.

[0052] It should be noted that the unlocking part 30 can push the second locking part 32 to move as a whole, so that the second locking part 32 and the first locking part 31 are in an unlocked state, thereby unlocking the door 2 and the cooking body 1, and pulling the door 2 can open the cooking body 1; the unlocking part 30 can also drive a part of the second locking part 32 to move, so that a part of the second locking part 32 moves relative to the first locking part 31, and the second locking part 32 and the first locking part 31 are in an unlocked state, thereby unlocking the door 2 and the cooking body 1, and pulling the door 2 can open the cooking body 1.

[0053] like Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, according to an embodiment of the present invention, the second locking part 32 further includes: a support 320 disposed on the cooking body 1, the support 320 having a limiting part 321; a locking structure 324 movably connected to the limiting part 321; an unlocking part 30 corresponding to the locking structure 324; the unlocking part 30 being able to push the locking structure 324 to move so that the locking structure 324 and the limiting part 321 switch between limiting engagement and unlocking; in the case of limiting engagement, the first locking part 31 and the locking structure 324 are in a locked state; in the case of unlocking, the first locking part 31 and the locking structure 324 are in an unlocked state.

[0054] In this embodiment, the second locking part 32 includes a bracket 320 and a locking structure 324. The bracket 320 is disposed on the cooking body 1, and the locking structure 324 is movably disposed on the limiting part 321 of the bracket 320. The unlocking part 30 is correspondingly disposed with the locking structure 324. Thus, the user can move the locking structure 324 by operating the unlocking part 30, so that the locking structure 324 and the limiting part 321 are either locked or unlocked. When the locking structure 324 and the limiting part 321 are locked, the locking structure 324 and the limiting part 321 are locked, and the first locking part 31 and the locking structure 324 are locked, so pulling the door 2 cannot open the cooking body 1. When the locking structure 324 and the limiting part 321 are unlocked, the locking structure 324 can move relative to the limiting part 321, so that the first locking part 31 and the locking structure 324 can be unlocked, and pulling the door 2 can open the cooking body 1.

[0055] It is understood that the locking structure 324 and the limiting part 321 have a limiting engagement connection state and a unlocked engagement state, and the locking structure 324 of the first locking part 31 and the second locking part 32 have a locked state and an unlocked state. Further, the engagement state between the first locking part 31 and the locking structure 324 is determined by the engagement state between the locking structure 324 and the limiting part 321. Specifically, when the locking structure 324 and the limiting part 321 are in a limiting engagement state, the locking structure 324 and the first locking part 31 are in a locked state, meaning the locking structure 324 cannot move relative to the limiting part 321 to unlock the first locking part 31 and the locking structure 324. When the limiting engagement between the locking structure 324 and the limiting part 321 is unlocked, the locking structure 324 and the first locking part 31 are in an unlocked state, meaning the locking structure 324 can move relative to the limiting part 321 to unlock the first locking part 31 and the locking structure 324.

[0056] In specific applications, the unlocking between the first locking part 31 and the locking structure 324 can be achieved by the unlocking part 30 pushing the locking structure 324 to move, thereby releasing the locking structure 324 from the limiting part 321, and simultaneously unlocking the locking structure 324 directly from the first locking part 31. That is, it is not necessary for the first locking part 31 or other structures to further drive the locking structure 324 to move. In other words, the unlocking part 30 directly pushes the locking structure 324 to the position where it is unlocked from the first locking part 31, thereby unlocking the first locking part 31 directly from the locking structure 324. Alternatively, after the unlocking part 30 pushes the locking structure 324 to move, thereby releasing the locking structure 324 from the limiting part 321, the first locking part 31 drives the locking structure 324 to move relative to the limiting part 321, thereby unlocking the first locking part 31 from the locking structure 324.

[0057] In practical applications, the bracket 320 is fixed to the cooking body 1.

[0058] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, according to an embodiment of the present invention, when the locking structure 324 and the limiting part 321 are released from their limiting positions, the first locking part 31 can drive the locking structure 324 to rotate relative to the limiting part 321, so as to separate the first locking part 31 from the locking structure 324 or to lock the first locking part 31 with the locking structure 324.

[0059] In this embodiment, when the locking structure 324 and the limiting part 321 are released from their limiting positions, the first locking part 31 drives the locking structure 324 to rotate relative to the limiting part 321, so that the locking structure 324 moves to a position where it can be separated from the first locking part 31, thereby opening the cooking body 1; or, the first locking part 31 can also drive the locking structure 324 to rotate relative to the limiting part 321, so that the locking structure 324 moves back to a state where it can be limited and engaged with the limiting part 321, and then the first locking part 31 locks with the limiting structure after the limiting part 321 and the locking structure 324 are limited and engaged. That is, when the unlocking part 30 pushes the locking structure 324 to move, so that the locking structure 324 and the limiting part 321 are released from their limiting positions, the locking structure 324 can rotate relative to the limiting part 321. At this time, when the door body 2 is pulled, the first locking part 31 on the door body 2 moves with the door body 2, so that the first locking part 31 drives the locking structure 324 to rotate until the first locking part 31 and the locking structure 324 are separated, thereby opening the cooking body 1. When closing the door, the door body 2 is pushed towards the cooking body 1, and the door body 2 drives the first locking part 31 to approach the locking structure 324. The first locking part 31 pushes the locking structure 324 to move, so that the locking structure 324 moves to a position where it can be limited and cooperated with the limiting part 321. The first locking part 31 and the locking structure 324 return to the locked state.

[0060] It is understandable that when the limiting part 321 and the locking structure 324 are engaged in a limiting action, the limiting part 321 limits the locking structure 324 in the rotational direction. That is, when the locking structure 324 and the limiting part 321 are locked, the locking structure 324 can only move in the pushing direction of the unlocking part 30 under the push of the unlocking part 30, and cannot rotate along the limiting part 321.

[0061] like Figure 5 and Figure 7 As shown, according to one embodiment of the present invention, the limiting part 321 further includes a rotating shaft 322 and a limiting block 323 disposed on the side wall of the rotating shaft 322; the locking structure 324 is provided with a shaft hole 325 and a limiting hole 326 extending radially from the shaft hole 325, and the rotating shaft 322 is disposed in the shaft hole 325; when the limiting engagement is performed, the limiting block 323 is disposed in the limiting hole 326, and the unlocking part 30 can push the locking structure 324 to move along the axial direction of the rotating shaft 322 so that the limiting block 323 is released from the limiting hole 326; when the limiting engagement is released, the limiting block 323 is separated from the limiting hole 326, and the first locking part 31 can drive the locking structure 324 to rotate so that the limiting block 323 is misaligned or corresponds to the limiting hole 326.

[0062] In this embodiment, the limiting part 321 includes a rotating shaft 322 and a limiting block 323, with the limiting block 323 disposed on the side wall of the rotating shaft 322. The locking structure 324 is provided with a shaft hole 325 and a limiting hole 326, with the limiting hole 326 disposed on the side wall of the shaft hole 325 and extending radially along the shaft hole 325. The rotating shaft 322 is disposed within the shaft hole 325. The engagement and disengagement of the limiting block 323 and the limiting hole 326 realize the limiting engagement or disengagement of the locking structure 324 and the limiting part 321. When the limiting block 323 is located within the limiting hole 326, the limiting block 323 restricts the rotation of the locking structure 324 along the circumferential direction of the rotating shaft 322 through the limiting hole 326, so that the locking structure 324 and the limiting part 321 are in a limiting engagement state, thereby locking the door 2 and the cooking body 1. In this case, the unlocking part 30 can drive the locking structure 324 to move, causing the limiting block 323 to separate from the limiting hole 326, thereby releasing the limiting part 321 and the locking structure 324 from the limiting state. When the limiting part 321 and the locking structure 324 are released from the limiting state, the first locking part 31 can drive the locking structure 324 to rotate, thereby causing the limiting block 323 to be misaligned or aligned with the limiting hole 326.

[0063] Specifically, such as Figure 5 As shown, after the unlocking part 30 is pressed, the limiting part 321 and the locking structure 324 are in the unlocked state. When the limiting part 321 and the locking structure 324 are in the unlocked state, as... Figure 7 As shown, when the user pulls the door 2, the first locking part 31 drives the locking structure 324 to rotate in the first direction until the first locking part 31 separates from the locking structure 324, and the limiting block 323 and the limiting hole 326 are misaligned. The misaligned limiting hole 326 and the limiting block 323 have an axial limiting effect on the locking structure 324, and the locking structure 324 will not move to its original position in the axial direction. Therefore, when the user needs to close the door 2, the first locking part 31 pushes the locking structure 324 to rotate in the second direction, so that the limiting block 323 corresponds to the limiting hole 326, thereby facilitating the re-positioning of the limiting block 323 and the limiting hole 326.

[0064] The first direction is opposite to the second direction. Specifically, one of the first and second directions is a clockwise direction around the axis 322, and the other is a counterclockwise direction.

[0065] It is understandable that when the locking structure 324 and the limiting part 321 are in a limiting engagement, the locking structure 324 and the limiting part 321 are in a limiting engagement along the circumferential direction of the rotating shaft 322. However, the locking structure 324 can move along the axial direction of the rotating shaft 322. Specifically, under the drive of the unlocking part 30, the locking structure 324 can move along the axial direction of the rotating shaft 322 so that the limiting block 323 is separated from the limiting hole 326. As a result, the limiting block 323 no longer limits the limiting hole 326, and the locking structure 324 can rotate around the rotating shaft 322, thereby unlocking the locking structure 324 and the first locking part 31.

[0066] like Figure 3 As shown, according to an embodiment of the present invention, the door lock assembly 3 further includes: a reset member 33, disposed between the side of the locking structure 324 away from the unlocking part 30 and the bracket 320; when the limiting hole 326 rotates to the position corresponding to the limiting block 323, the reset member 33 pushes the locking structure 324 to reset, so that the limiting block 323 and the limiting hole 326 are in a limiting engagement.

[0067] In this embodiment, the cooking appliance further includes a reset member 33, which is disposed between the side of the locking structure 324 away from the unlocking part 30 and the bracket 320. The reset member 33 is used to reset the locking structure 324, thereby causing the limiting block 323 to engage with the limiting hole 326.

[0068] Specifically, when it is necessary to unlock the cooking appliance, the unlocking part 30 pushes the locking structure 324 to move axially along the rotating shaft 322. The locking structure 324 presses the reset member 33 in the direction of the reset member 33, causing the reset member 33 to deform and the limiting block 323 to separate from the limiting hole 326. Then, the user pulls the door 2, and the first locking part 31 on the door 2 drives the locking structure 324 to rotate, causing the limiting block 323 to misalign with the limiting hole 326 and the first locking part 31 to separate from the locking structure 324, thereby realizing the opening of the cooking body 1. At this time, because the limiting block 323 and the limiting hole 326 are misaligned, the reset member 33 cannot reset the locking structure 324. When the user closes the door 2, the first locking part 31 on the door 2 pushes the locking structure 324 to rotate, so that the limiting hole 326 corresponds to the limiting block 323. Then the reset part 33 restores its deformation and pushes the locking structure 324 to move towards the unlocking part 30, so that the limiting hole 326 and the limiting block 323 are in a limited engagement, and the first locking part 31 and the second locking part 32 are in a locked state, realizing the self-locking of the cooking appliance.

[0069] In a specific application, the reset element 33 includes a spring.

[0070] like Figure 5As shown, according to one embodiment of the present invention, the locking structure 324 is further provided with a hook groove 327. Along the rotation direction of the locking structure 324, the hook groove 327 includes a first wall surface 3270 and a second wall surface 3272 disposed opposite to each other, the first wall surface 3270 and the second wall surface 3272 surrounding a groove opening 3274; as shown... Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the first locking part 31 includes a door hook 310. The door hook 310 extends into or out of the hook groove 327 through the slot 3274. The door hook 310 can drive the locking structure 324 to rotate through the first wall surface 3270 or the second wall surface 3272.

[0071] In this embodiment, the locking structure 324 is provided with a hook groove 327, and the first locking part 31 includes a door hook 310 that can cooperate with the hook groove 327. The hook groove 327 includes a first wall surface 3270 and a second wall surface 3272 disposed opposite to each other, and a slot 3274 enclosed by the first wall surface 3270 and the second wall surface 3272. The door hook 310 extends into the hook groove 327 through the slot 3274 to limit its position with the hook groove 327, or moves out of the hook groove 327 through the slot 3274 to separate from the hook groove 327. The door hook 310 pushes the locking structure 324 to rotate through the first wall surface 3270 or the second wall surface 3272, thereby achieving the limiting or separation of the door hook 310 from the hook groove 327.

[0072] In practical applications, when the limiting part 321 and the locking structure 324 are released from their limiting positions, the user pulls the door body 2, and the door hook 310 drives the locking structure 324 to rotate through the first wall surface 3270 of the hook groove 327, so that the door hook 310 can disengage from the groove 3274; when the user closes the door body 2, the door hook 310 drives the locking structure 324 to rotate through the second wall surface 3272 of the hook groove 327, so that the door hook 310 can extend into the hook groove 327 from the groove 3274. When the limiting hole 326 rotates to the position corresponding to the limiting block 323, under the action of the reset member 33, the limiting block 323 and the limiting hole 326 are limited and engaged, and the door hook 310 and the hook groove 327 are locked.

[0073] Furthermore, the length of the second wall 3272 is greater than the length of the first wall 3270.

[0074] like Figure 3 As shown, according to one embodiment of the present invention, the bracket 320 is further provided with an opening 328, and the door hook 310 extends into or moves out of the hook groove 327 through the opening 328; when the limit is released, the door hook 310 can pull the hook groove 327 to move so that the groove 3274 is correspondingly set with the opening 328.

[0075] In this embodiment, the bracket 320 is provided with an opening 328. The door hook 310 extends into or moves out of the hook groove 327 through the opening 328. When the limiting block 323 and the limiting hole 326 are released, the door hook 310 can drive the locking structure 324 to rotate, so that the groove 3274 corresponds to the opening 328. Then, the door hook 310 can move out from the groove 3274 and the opening 328, so that the door hook 310 separates from the second locking part 32, thereby realizing the opening of the cooking body 1.

[0076] Correspondingly, when the door 2 is closed, the door hook 310 can also extend into the slot 3274 through the opening 328, thereby driving the locking structure 324 to rotate, so that the locking structure 324 and the limiting part 321 are in a limiting engagement.

[0077] like Figure 3 As shown, according to one embodiment of the present invention, the door lock assembly 3 further includes a torsion spring 34, which is connected to the locking structure 324 and the bracket 320. In the locked state and the unlocked state, the torsion spring 34 is in a deformed state.

[0078] In this embodiment, the cooking appliance also includes a torsion spring 34, which is connected to the bracket 320 and the locking structure 324 to ensure stable movement of the locking structure 324.

[0079] In a specific application, the torsion spring 34 includes a first connecting post and a second connecting post, as well as a torsion spring portion disposed between the first connecting post and the second connecting post. The first connecting post extends into the locking structure 324 along the axial direction of the rotating shaft 322 and is rotatable relative to the locking structure 324. The second connecting post is inserted into the bracket 320 along the axial direction of the rotating shaft 322 and is rotatable relative to the bracket 320.

[0080] Furthermore, the bracket 320 is also provided with a limiting structure. After the limiting part 321 and the locking structure 324 are released from the limiting position, during the process of the user opening the door 2, the first locking part 31 drives the locking structure 324 to rotate in the first direction. After the locking structure 324 rotates to the position, the locking structure 324 abuts against the limiting structure, and the torsion spring 34 deforms and pushes the locking structure 324 in the direction of the limiting structure (i.e., along the first direction), so that the locking structure 324 stops stably at this position. The torsion spring 34 provides assistance for opening the door 2. During the process of the user closing the door 2, the first locking part 31 drives the locking structure 324 to rotate in the second direction, and the torsion spring 34 also moves accordingly. When the locking structure 324 moves to the position where it is limited and engaged with the limiting part 321, the torsion spring 34 pushes the locking structure 324 in the second direction, so that the locking structure 324 is stably engaged with the first limiting part 321.

[0081] like Figure 1As shown, according to one embodiment of the present invention, the unlocking part 30 is further provided on the side wall of the cooking body 1.

[0082] In this embodiment, the unlocking part 30 is provided on the side wall of the cooking body 1 to facilitate user operation.

[0083] like Figure 3 As shown, according to an embodiment of the present invention, the cooking body 1 further includes: a housing 10, the housing 10 including a cooking cavity 102, and a second locking part 32 disposed on the outer side wall of the housing 10; an outer cover 12 disposed on the outer side wall of the housing 10, and an unlocking part 30 disposed on the outer cover 12.

[0084] In this embodiment, the cooking body 1 includes a housing 10 and an outer cover 12. The housing 10 includes a cooking cavity 102, and a door 2 is used to open or close the cooking cavity 102. The outer cover 12 is disposed on the outer side wall of the housing 10, a second locking part 32 is disposed on the outer side wall of the housing 10, and an unlocking part 30 is disposed on the outer cover 12 and corresponding to the second locking part 32. Thus, by operating the unlocking part 30, the second locking part 32 can be unlocked from the first locking part 31.

[0085] According to one embodiment of the present invention, the outer cover 12 is further provided with a mounting hole 120, which corresponds to the second locking part 32; the unlocking part 30 includes a button 302 and a button groove 304, the button groove 304 is disposed in the mounting hole 120, and the button 302 is slidably disposed in the button groove 304.

[0086] In this embodiment, the unlocking part 30 includes a button 302 and a button groove 304. The outer cover 12 is provided with a mounting hole 120. The button groove 304 is disposed in the mounting hole 120, and the button 302 is disposed in the button groove 304. The button 302 can slide relative to the button groove 304, thereby driving the second locking part 32.

[0087] In a specific application, the unlocking part 30 also includes a reset spring, which is connected to the button 302 and the outer cover 12 to reset the button 302.

[0088] Specifically, cooking appliances include microwave ovens, ovens, steam ovens, or steam ovens.

[0089] In practical applications, for the two-step opening of a pull-down microwave oven, the button 302 on the side of the outer cover 12 is pressed first, and then the door is pulled down to achieve the two-step structure (e.g., Figure 1 (As shown). The door lock assembly 3 consists of a button slot 304, a button 302, a locking structure 324, a torsion spring 34, a bracket 320, a reset element 33 (spring), and a door hook 310 (as shown). Figure 3 As shown), the functions of each part of the door lock assembly 3 are as follows:

[0090] Button slot 304: It is fixed to the outer cover 12 with screws to ensure the stable movement of button 302.

[0091] Button 302: Moves in button slot 304. When the user presses button 302, it will push locking structure 324 to move axially inward along bracket 320.

[0092] Locking structure 324: Installed on bracket 320, it rotates around the pivot 322 on bracket 320 and rotates with door hook 310 when opening and closing the door.

[0093] Torsion spring 34: ensures stable movement of locking structure 324 when opening and closing the door, and also increases the opening force to a certain extent.

[0094] Support 320: Fixed to the outer wall of the cooking cavity 102, supporting the movement of the locking structure 324.

[0095] Spring: Fitted on the pivot 322 of the bracket 320, providing restoring force for the locking structure 324.

[0096] Door hook 310: Fixed to the door body 2, when the door body 2 is closed, the door hook 310 is embedded in the hook groove of the locking structure 324.

[0097] When the door 2 is closed, the door hook 310 is engaged in the groove of the locking structure 324. At this time, because the limiting hole 326 (groove-shaped) in the middle of the locking structure 324 and the limiting block 323 (buckle-shaped) on the rotating shaft 322 are locked, the locking structure 324 cannot rotate, and therefore the door hook 310 cannot move. This state is the locked state (i.e., the child lock state).

[0098] When the user presses the side button 302, the locking structure 324 moves along the rotating shaft 322, thus disengaging the groove of the locking structure 324 from the latch on the rotating shaft 322, allowing the locking structure 324 to rotate (e.g., Figures 4 to 7 As shown), the user can open the door by pulling down the door body 2. At this time, the locking structure 324 is located below the latch on the pivot 322 (as shown). Figure 7 As shown, the door hook 310 can disengage from the hook groove of the locking structure 324 to open the door.

[0099] During the process of the user closing the door 2, the door hook 310 will push the locking structure 324 to rotate. When the locking structure 324 rotates to the state where its groove corresponds to the buckle on the rotating shaft 322, the locking structure 324 will return to the locked state due to the spring below, thus completing the function of automatically locking when closing the door.

[0100] The microwave oven proposed in this application can be locked after the door 2 is closed. To open the door, first press button 302 on the side cover 12, then pull the door down. It features a simple structure, low cost, convenient and quick operation, and high safety and reliability.
