Door lock apparatus and cooking appliance

Abstract

The present application specifically relates to a door lock apparatus and a cooking appliance. The door lock apparatus comprises an engagement member and a locking assembly. The engagement member comprises a first hook and a second hook having opposite openings. The locking assembly comprises a bracket, and a first locking mechanism, a second locking mechanism, and a damping mechanism which are separately mounted on the bracket. The first locking mechanism cooperates with the damping mechanism and comprises a first state and a second state. A door closing force drives the first hook to cooperate with the first locking mechanism, so that the first hook at least overcomes resistance of the damping mechanism and moves relative to the bracket, so that the first locking mechanism switches from the first state to the second state. In the second state, the door closing force is released, and the first locking mechanism drives the first hook to move, so that the first hook is locked on the first locking mechanism and the second hook is locked on the second locking mechanism. The door lock apparatus reduces the door closing force applied when a door body is closed, and a damping force of the damping mechanism slows down the speed of door closing, thereby reducing hitting of a cavity by the door body.

Door lock devices and cooking appliances

[0001] Cross-reference to related applications

[0002] This application claims priority and benefit from the following patent applications, the entire contents of which are incorporated herein by reference:

[0003] A Chinese patent application, filed on August 30, 2024, with application number 202411218300.7 and titled "Door Lock Device and Cooking Appliance", was submitted to the China National Intellectual Property Administration. Technical Field

[0004] This application relates to the field of cooking appliance technology, specifically to a door lock device and a cooking appliance. Background Technology

[0005] In related technologies, cooking appliances have a cavity and a door, with the door rotatably mounted on the cavity. The door can open or close the cavity opening under external force and is locked by a door locking device.

[0006] However, a large external force needs to be applied to the door during the closing process, and the door is prone to hitting the cavity during the closing process, which makes a lot of noise and reduces the user experience. Summary of the Invention

[0007] The purpose of this application is to at least solve the problems of reducing external force during door closing and the impact of the door on the cavity. This purpose is achieved through the following technical solution:

[0008] The first aspect of this application discloses a door lock device for a cooking appliance, the cooking appliance including a door body and a cavity having an opening, the door body being pivotally connected to the cavity and used to open or close the opening, the door lock device comprising:

[0009] A retaining element is used to fix the appliance to the door. The retaining element includes a first hook and a second hook that are arranged parallel to each other. The openings of the first hook and the second hook face each other, and the length of the first hook is greater than the length of the second hook.

[0010] A locking assembly includes a bracket, and a first locking mechanism, a second locking mechanism, and a damping mechanism respectively mounted on the bracket. The bracket is used to install on the cavity and is located on one side of the opening. The first locking mechanism cooperates with the damping mechanism and includes a first state and a second state that can be switched between each other. A closing force drives the first hook to cooperate with the first locking mechanism, causing the first hook to move relative to the bracket, so that the first locking mechanism switches from the first state to the second state. In the second state, the closing force is released, and the first locking mechanism drives the first hook to move against the resistance of the damping mechanism, so that the first hook locks with the first locking mechanism and the second hook locks with the second locking mechanism.

[0011] When the door lock device described in this application is used in a cooking appliance, an external force drives the door to close the opening of the cavity. The closing force acts on the door, causing the first hook to engage with the first locking mechanism. When the first locking mechanism switches from the first state to the second state, the closing force can be released. The first locking mechanism engages with the first hook to drive the first hook to move relative to the bracket until the first hook locks with the first locking mechanism and the second hook locks with the second locking mechanism.

[0012] The first locking mechanism is used to drive the first hook to move relative to the bracket, which realizes the locking of the first hook with the first locking mechanism and the cooperation of the second hook with the second locking mechanism. This reduces the closing force applied when the door is closed. At the same time, the damping force generated by the damping mechanism can slow down the closing speed, thereby reducing the impact of the door on the cavity and improving the user experience.

[0013] In addition, the door lock device according to this application may also have the following additional technical features:

[0014] In some embodiments of this application, the first locking mechanism includes:

[0015] A first rotating member is rotatably mounted on the bracket, and the first rotating member includes a first slot;

[0016] A limiting member is rotatably disposed on the bracket, and the limiting member is detachably engaged with the first rotating member to limit the rotation of the first rotating member relative to the bracket.

[0017] The first elastic element cooperates with the bracket and the first rotating element respectively. The first elastic element is set to a stretched state and has a first rebound force. Under the drive of the closing force, the first hook drives the limiting element to release the limiting of the first rotating element. The first rotating element, which is released from the limiting, rotates relative to the bracket under the action of the first rebound force. The first slot drives the first hook to move relative to the bracket. When the door closes the opening, the first hook engages with the first slot, and the second hook engages with the second locking mechanism.

[0018] In some embodiments of this application, the first elastic element is a tension spring, with the first end of the tension spring attached to the bracket and the second end of the tension spring attached to the first rotating element.

[0019] In some embodiments of this application, the tension spring and the first rotating member are disposed on opposite sides of the bracket.

[0020] In some embodiments of this application, the bracket is provided with an arc-shaped hole, the arc-shaped hole extends along the rotation direction of the first rotating member, the first rotating member includes a first protrusion, the first protrusion is slidably inserted through the arc-shaped hole, a part of the body of the first protrusion protrudes out of the arc-shaped hole, and the second end is hung on the body of the first protrusion protruding out of the arc-shaped hole;

[0021] And / or, the bracket is provided with a second protrusion, the second protrusion is disposed on the side of the bracket away from the first rotating member, and the first end is hung on the second protrusion.

[0022] In some embodiments of this application, the first locking mechanism further includes a second elastic element, which cooperates with the limiting element and the bracket respectively. The second elastic element has a second rebound force, which drives the limiting element to have a tendency to limit and cooperate with the first rotating element.

[0023] In some embodiments of this application, the limiting member includes a limiting groove, the first rotating member includes a limiting protrusion, and the second rebound force drives the limiting protrusion to engage in the limiting groove. Under the drive of the closing force, the first hook drives the limiting member to rotate relative to the bracket, so that the limiting protrusion separates from the limiting groove. When the closing force is released, the first rebound force drives the first rotating member to rotate relative to the bracket, and the first groove drives the first hook to move relative to the bracket, so that the first hook engages in the first groove and the second hook engages with the second locking mechanism.

[0024] In some embodiments of this application, the damping mechanism includes a damping element mounted on the bracket. The damping element includes a movable end, which is pulsatorically connected to the first rotating member. When switching from the first state to the second state, the damping element is fixed relative to the bracket and provides damping force to the first locking mechanism to limit the closing speed of the door. When switching from the second state to the first state, the damping element moves relative to the bracket and releases the damping force on the first locking mechanism.

[0025] In some embodiments of this application, the damping mechanism further includes a transmission component, which is tractively connected to the first rotating component and the movable end, respectively.

[0026] In some embodiments of this application, the first transmission member includes continuous teeth arranged along the rotation direction of the first rotating member. The transmission member is movably arranged on the bracket and is a rack. The rack meshes with the continuous teeth and is connected to the movable end. The movement direction of the damping member is consistent with the movement direction of the rack.

[0027] In some embodiments of this application, the bracket is provided with a mounting groove, the damping element is a damper, the damper is disposed in the mounting groove, the damper includes a cylinder and a damping rod that are movably connected, the movable end is the free end of the damping rod, when switching from the first state to the second state, the side wall of the mounting groove away from the movable end abuts against the cylinder and provides damping force to the first locking mechanism to limit the closing speed of the door, when switching from the second state to the first state, the rack drives the cylinder to move relative to the mounting groove through the movable end and releases the damping force on the first locking mechanism.

[0028] In some embodiments of this application, the first locking mechanism further includes a first detection element, which is installed on the bracket. When the door is closed and the opening is closed, the first hook engages with the first slot, the second hook locks with the second locking mechanism, and the first rotating member triggers the first detection element.

[0029] In some embodiments of this application, the second locking mechanism includes a second rotating member rotatably mounted on the bracket. The second rotating member includes a second slot, and when the door is closed, the second hook engages with the second slot.

[0030] In some embodiments of this application, the second locking mechanism further includes a third elastic element, which cooperates with the bracket and the second rotating member respectively. The third elastic element has a third rebound force. When the second hook is not engaged in the second slot, the third rebound force drives the second rotating member to rotate in a first direction. When the second hook is engaged in the second slot, the third rebound force drives the second rotating member to rotate in a second direction. The first direction is opposite to the second direction.

[0031] In some embodiments of this application, the volume of the first hook is larger than the volume of the second hook.

[0032] A second aspect of this application provides a cooking appliance, said cooking appliance comprising:

[0033] A cavity, the cavity including an opening;

[0034] A door body, which is pivotally connected to the cavity and is used to open or close the opening;

[0035] According to the door lock device described above, the latching member of the door lock device is installed on the door body, and the bracket of the locking assembly of the door lock device is installed in the cavity and located on one side of the opening.

[0036] According to the cooking appliance of this application, an external force drives the door to close the opening of the cavity. The closing force acts on the door, causing the first hook to engage with the first locking mechanism. When the first locking mechanism switches from the first state to the second state, the closing force can be released. The first locking mechanism engages with the first hook to drive the first hook to move relative to the bracket until the first hook engages with the first locking mechanism and the second hook engages with the second locking mechanism.

[0037] The first locking mechanism is used to drive the first hook to move relative to the bracket, which realizes the locking of the first hook with the first locking mechanism and the cooperation of the second hook with the second locking mechanism. This reduces the closing force applied when the door is closed. At the same time, the damping force generated by the damping mechanism can slow down the closing speed, thereby reducing the impact of the door on the cavity and improving the user experience.

[0054] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0055] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also mean including the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0056] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0057] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations.

[0058] As shown in Figures 1 to 14, according to an embodiment of this application, a door lock device 300 for a cooking appliance 1000 is proposed. The cooking appliance 1000 includes a cavity 200 and a door 100. The cavity 200 has an opening, through which the cooking cavity inside the cavity 200 is connected to the outside. The door 100 is connected to the cavity 200 and is pivotable relative to the cavity 200. The pivoting of the door 100 relative to the cavity 200 performs the operation of opening or closing the opening of the cavity 200.

[0059] In this application, the door lock device 300 includes a locking assembly 20 and a retaining member 10. The retaining member 10 is fixedly mounted on the door body 100, and the locking assembly 20 is fixedly mounted on the cavity 200. The door body 100 drives the retaining member 10 to move synchronously. When the door body 100 closes the opening of the cavity 200, the retaining member 10 is locked to the door lock device 300. When the door body 100 opens the opening of the cavity 200, the retaining member 10 is released from the door lock device 300.

[0060] In some embodiments of this application, as shown in Figures 2 to 4 and Figures 9 to 14, the retaining member 10 includes a first hook 11 and a second hook 13, wherein the first hook 11 and the second hook 13 are arranged in parallel at intervals and their opening directions are facing each other.

[0061] In some embodiments of this application, the volume of the first hook 11 is larger than the volume of the second hook 13.

[0062] For example, the length of the first hook 11 is greater than the length of the second hook 13.

[0063] It should be understood that the first hook 11 includes a first hook portion with a first opening, and the second hook 13 includes a second hook portion with a second opening. The fact that the openings of the first hook 11 and the second hook 13 are arranged facing each other means that the first opening and the second opening are oriented opposite to each other.

[0064] In addition, in this application, when the retaining member 10 cooperates with the locking assembly 20, the retaining member 10 has a moving direction. In the moving direction of the retaining member 10, the size of the first hook 11 is the length of the first hook 11, and the size of the second hook 13 is the length of the second hook 13.

[0065] Furthermore, when the retaining member 10 is locked to the locking assembly 20, since the length of the first hook 11 is greater than the length of the second hook 13, the first hook 11 engages with the locking assembly 20 first. After the first hook 11 moves a certain distance relative to the locking assembly 20, the second hook 13 engages with the locking assembly 20, and finally the first hook 11 and the second hook 13 are locked to the locking assembly 20 respectively, thereby keeping the door 100 in the open state of the closed cavity 200.

[0066] For example, along the first direction, the size of the first hook 11 is larger than the size of the second hook 13, wherein the first direction is the length direction of the cavity 200.

[0067] By adjusting the dimensions of the first hook 11 and the second hook 13 in the first direction, the volume of the second hook 13 can be reduced while effectively closing the door 100. This reduces the size of the second insertion hole 234 on the bracket through which the second hook 13 passes, preventing foreign objects from entering the locking assembly through the second insertion hole 234 and further reducing the failure rate of the door lock device 300.

[0068] It should be understood that, in this application, when the user faces the cooking appliance 1000 in its placed state, the direction in which the left and right sides of the cooking appliance 1000 are arranged is the length direction of the cooking appliance 1000, which is the length direction of the cavity 200.

[0069] For example, along the second direction, the size of the first hook 11 is larger than the size of the second hook 13, wherein the second direction is the height direction of the cavity 200.

[0070] By adjusting the dimensions of the first hook 11 and the second hook 13 in the first direction, the volume of the second hook 13 can be reduced while effectively closing the door 100. This reduces the size of the second insertion hole 234 on the bracket through which the second hook 13 passes, preventing foreign objects from entering the locking assembly through the second insertion hole 234 and further reducing the failure rate of the door lock device 300.

[0071] It should be understood that, in this application, when the user faces the cooking appliance 1000 in its placed state, the direction in which the top and bottom of the cooking appliance 1000 are arranged is the height direction of the cooking appliance 1000, which is the height direction of the cavity 200.

[0072] In some embodiments of this application, as shown in Figures 2 to 4 and Figures 7 to 14, the locking assembly 20 includes a bracket 23, a first locking mechanism 21, a second locking mechanism 24, and a damping mechanism 22. The first locking mechanism 21, the second locking mechanism 24, and the damping mechanism 22 are respectively mounted on the bracket 23. The bracket 23 is connected and fixed to the cavity 200 of the cooking appliance 1000. The damping mechanism 22 is connected to the first locking mechanism 21 in a transmission manner. The first locking mechanism 21 is disposed opposite to the first hook 11, and the second locking mechanism 24 is disposed opposite to the second hook 13.

[0073] The first locking mechanism 21 includes a first state and a second state, which can be switched between each other. During the locking process of the retaining member 10 and the lock attachment, the first hook 11 cooperates with the first locking mechanism 21, so that the first locking mechanism 21 switches from the first state to the second state, and the first hook 11 locks with the first locking mechanism 21 in the second state.

[0074] When the door lock device 300 is used with the cooking appliance 1000, the user applies a closing force to the door 100 while closing the opening of the cavity 200. Under the action of the closing force, the door 100 rotates relative to the cavity 200. The latch 10 moves towards the cavity 200 as the door 100 rotates. The first latch 11 first engages with the first locking mechanism 21. Driven by the closing force, the latch moves relative to the bracket 23 and drives the first locking mechanism 21. Driven by the first latch 11, the first locking mechanism 21 switches from a first state to a second state. In the second state, the damping mechanism 22 applies a damping force to the first locking mechanism 21. The damping force acts on the first latch 11 through the first locking mechanism 21. The direction of the damping force is opposite to the direction of movement of the first latch 11 relative to the bracket 23. Under the action of the damping force, the movement speed of the first latch 11 relative to the bracket 23 is reduced, thereby reducing the possibility of the door 100 colliding with the cavity 200.

[0075] When the first locking mechanism 21 switches from the first state to the second state, the user releases the closing force. The first locking mechanism 21 cooperates with the first hook 11 and provides driving force to the first hook 11. Under the drive of this driving force, the first locking mechanism 21 drives the first hook 11 to continue moving relative to the bracket 23 until the first hook 11 is locked in place with the first locking mechanism 21 (i.e., locked). During the process of the first locking mechanism driving the first hook 11 to move relative to the bracket 23, the second hook 13 cooperates with the second locking mechanism 24. When the first hook 11 is locked with the first locking mechanism 21, the second hook 13 is also locked with the second locking mechanism 24.

[0076] When the door 100 is closed and the cavity 200 is closed, if the user needs to open the door 100, by applying an opening force to the door 100 (in the opposite direction to the closing force), the first locking mechanism 21 and the first hook 11 are disengaged, the first locking mechanism 21 switches from the second state to the first state, and the second locking mechanism 24 and the second hook 13 are disengaged, thereby realizing the door opening operation.

[0077] It should be understood that locking the first hook 11 with the first locking mechanism 21 means that the first hook 11 and the first locking mechanism 21 are engaged in place, and the first locking mechanism 21 locks the first hook 11 to restrict the position of the first hook 11, that is, the first hook 11 is in a locked state; similarly, locking the second hook 13 with the second locking mechanism 24 means that the second hook 13 and the second locking mechanism 24 are engaged in place, and the second locking mechanism 24 locks the second hook 13 to restrict the position of the second hook 13, that is, the second hook 13 is in a locked state.

[0078] When the door lock device 300 of this application is used in the cooking appliance 1000, an external force drives the door body 100 to close the opening of the cavity 200. The closing force acts on the door body 100, causing the first hook 11 to engage with the first locking mechanism 21. When the first locking mechanism 21 switches from the first state to the second state, the closing force can be released. The first locking mechanism 21 engages with the first hook 11 to drive the first hook 11 to move relative to the bracket 23 until the first hook 11 engages with the first locking mechanism 21 and the second hook 13 engages with the second locking mechanism 24. The first locking mechanism 21 is used to drive the first hook 11 to move relative to the bracket 23, which realizes the locking of the first hook 11 with the first locking mechanism 21 and the cooperation of the second hook 13 with the second locking mechanism 24. This reduces the closing force applied when the door 100 is closed. At the same time, the damping force generated by the damping mechanism 22 can slow down the closing speed, thereby reducing the impact of the door 100 on the cavity 200, and thus improving the user experience.

[0079] It should be noted that in this application, the bracket 23 has a snap-in end, which is disposed facing the card holder 10. The first locking mechanism 21, the second locking mechanism 24 and the damping mechanism 22 are respectively disposed on the bracket 23. The snap-in end includes a second insertion hole 233 and a second insertion hole 234 disposed at intervals. The second insertion hole 233 is disposed opposite to the first hook 11 and the second insertion hole 234 is disposed opposite to the second hook 13. The first locking mechanism 21 is disposed on the side of the snap-in end away from the card holder 10 and the second locking mechanism 24 is disposed on the side of the snap-in end away from the card holder 10.

[0080] When the retaining member 10 engages with the locking assembly 20, the first hook 11 is inserted into the bracket 23 through the second insertion hole 233 and locked with the first locking mechanism 21, and the second hook 13 is inserted into the bracket 23 through the second insertion hole 234 and locked with the second locking mechanism 24.

[0081] The bracket 23 is an integral structure. This integral structure bracket 23 can be manufactured by stamping, die casting, injection molding or casting, which reduces the number of processing steps and improves processing efficiency. At the same time, the integral structure bracket 23 has high structural strength and can provide a stable bearing platform for the first locking mechanism 21, the second locking mechanism 24 and the damping mechanism 22, so that the first locking mechanism 21, the second locking mechanism 24 and the damping mechanism 22 can give full play to their performance, thereby reducing the failure rate of the door lock device 300.

[0082] In addition, the retaining member 10 also includes a mounting part 12, and a first hook 11 and a second hook 13 are respectively disposed on the mounting part 12. The first hook 11 and the mounting part 12 can be an integral structure or a separate structure, and the second hook 13 and the mounting part 12 can be an integral structure or a separate structure.

[0083] When the mounting part 12, the first hook 11, and the second hook 13 are separate structures, the first hook 11 can be fixed to the mounting part 12 by bonding, welding, snapping, or fastening. Similarly, the second hook 13 can also be fixed to the mounting part 12 by bonding, welding, snapping, or fastening. The mounting part 12, the first hook 11, and the second hook 13 are separate structures, and the materials of the three parts can be completely the same, partially the same, or completely different. For example, the mounting part 12 can be made of plastic, the first hook 11 of metal, and the second hook 13 of metal. The first hook 11 and the second hook 13, being metal parts, are fixed to the mounting part 12 by fasteners such as screws.

[0084] When the mounting part 12, the first hook 11, and the second hook 13 are integrated structures, they can be manufactured by stamping, die casting, injection molding, or casting, which reduces the number of processing steps and improves processing efficiency. At the same time, the integrated structure of the holding part 10 has high structural strength, which reduces the problem of breakage or deformation of the first hook 11 or the second hook 13 during use, thereby reducing the failure rate of the door lock device 300.

[0085] In some embodiments of this application, as shown in Figures 2 to 4 and Figures 9 to 14, the first locking mechanism 21 includes a first rotating member 211, a limiting member 212, and a first elastic member 215.

[0086] Specifically, the first rotating member 211 is mounted on the bracket 23 and is capable of rotating relative to the bracket 23. When the retaining member 10 cooperates with the locking assembly 20, the retaining member 10 has a moving direction relative to the bracket 23, and the rotation axis of the first rotating member 211 is perpendicular to the moving direction.

[0087] A first mounting post 236 (e.g., integrally formed with the bracket 23) is provided on the bracket 23, and a first mounting hole 2116 is provided on the first rotating member 211. The first mounting post 236 is inserted into the first mounting hole 2116, and a first limiting member is provided at the end of the first mounting post 236 protruding from the first mounting hole 2116, thereby realizing the rotatable connection between the first rotating member 211 and the bracket 23. This structure is simple, can effectively reduce manufacturing costs, and is easy to assemble, which can effectively improve assembly efficiency.

[0088] A first slot 2113 is provided on the first rotating member 211, and a first holding device is provided on the outer peripheral wall of the first rotating member 211. The first slot 2113 is used to cooperate with the first hook 11.

[0089] The limiting member 212 is installed on the bracket 23 and can rotate relative to the bracket 23. When the clamping member 10 is separated from the locking assembly 20, the limiting member 212 and the first rotating member 211 are limited to each other (the cooperation between the first rotating member 211 and the limiting member can be separated). Under the action of the limiting member 212, the first rotating member 211 cannot rotate relative to the bracket 23.

[0090] The first elastic element 215 cooperates with the first rotating element 211 and the bracket 23 respectively. The first elastic element 215 is in a stretched state. The first elastic element 215 in the stretched state has a first rebound force. The first rebound force causes the first rotating element 211 to have a rotation tendency. Driven by the first rebound force, the first locking mechanism 21 has a tendency to switch from the first state to the second state.

[0091] When the door lock device 300 is used with the cooking appliance 1000, during the process of closing the opening of the cavity 200, the user applies a closing force to the door 100. Under the action of the closing force, the door 100 rotates relative to the cavity 200. The retaining member 10 moves towards the cavity 200 as the door 100 rotates. The first hook 11 first engages with the limiting member 212. During the movement of the first hook 11 relative to the bracket 23, it applies an external force to the limiting member 212, causing the limiting member 212 to move away from the first rotating member 211, so that the limiting member 212 releases its restriction on the first rotating member 211. The first rebound force provided by the elastic component 215 drives the first rotating component 211, causing the first rotating component 211 to rotate relative to the bracket 23. During the rotation of the first rotating component 211, the first slot 2113 engages with the first hook 11 and drives the hook to continue moving relative to the bracket 23 (overcoming the damping force provided by the damping mechanism 22 during the movement). When the first hook 11 moves to the limit position relative to the bracket 23, the first hook 11 engages with the first slot 2113, and at the same time, the second hook 13 engages with the second locking mechanism 24, thereby keeping the door 100 in the open state of the closed cavity 200.

[0092] When the door 100 is closed and the cavity 200 is closed, if the user needs to open the door 100, by applying an opening force to the door 100 (in the opposite direction to the closing force), the second hook 13 unlocks the second locking mechanism 24, and the first hook 11 drives the first slot 2113, causing the first rotating member 211 to rotate in the opposite direction against the first rebound force of the first elastic member 215. When the first rotating member 211 returns to its initial state, when the first hook 11 separates from the first slot 2113 and avoids the position of the limiting member 212, the limiting member 212 cooperates with the first rotating member 211 again to limit the first rotating member 211, thereby realizing the door opening operation.

[0093] By using the limiting member 212 to limit the first rotating member 211, the first rotating member 211 tends to switch to the second state. When the user closes the door, only a small force is needed to drive the limiting member 212 to release the limitation on the first rotating member 211. After the limitation is released, the first rotating member 211 can drive the first hook 11. Without any external force applied by the user, the first rotating member 211 can lock the holding member 10 and the locking assembly 20 by driving the first hook 11 to move. This can effectively reduce the closing force when the user closes the door, thus effectively improving the user experience.

[0094] It is required that the first elastic element 215 is in a stretched state, wherein the first elastic element 215 includes, but is not limited to, elastic ropes and tension springs.

[0095] In some embodiments of this application, as shown in Figures 3 and 4, the first elastic member 215 is configured as a tension spring, which includes a first end and a second end arranged opposite to each other. The first end of the tension spring is engaged with the bracket 23 in a hanging manner, and the second end of the tension spring is engaged with the first rotating member 211 in a hanging manner.

[0096] The first elastic element 215 is set as a tension spring, which can provide a continuous and stable first rebound force to the first rotating element 211, reducing the plastic deformation caused by long-term use, thereby reducing the failure rate of the door lock device 300.

[0097] In addition, the tension spring has a simple structure and is easy to install, which can shorten the assembly time and effectively improve the assembly efficiency.

[0098] In addition, the wide availability of tension spring materials can effectively reduce manufacturing, repair, and replacement costs.

[0099] It should be noted that a first hanging hole or a first protrusion can be provided on the bracket 23, and the first end of the tension spring can be mounted and cooperated with the first hanging hole or the first protrusion. A second hanging hole or a second protrusion can be provided on the first rotating member 211, and the second end of the tension spring can be mounted and cooperated with the second hanging hole or the second protrusion.

[0100] In addition, the tension spring and the first rotating member 211 can be set on the same side of the bracket 23 or on opposite sides.

[0101] In some embodiments of this application, as shown in Figures 3 and 4, the first rotating member 211 and the tension spring are disposed on opposite sides of the bracket 23. By disposing the first rotating member 211 and the tension spring on opposite sides of the bracket 23, interference between the first rotating member 211 and the tension spring can be reduced, thereby reducing the failure rate of the door lock device 300.

[0102] In some embodiments of this application, as shown in Figures 3 to 8, 10, 12 and 14, the first rotating member 211 is mounted on the bracket 23 and can rotate relative to the bracket 23. The bracket 23 has an arc-shaped hole 232 extending along the rotation direction of the first rotating member 211. The first rotating member 211 includes a first protrusion 2111 passing through the arc-shaped hole 232. A portion of the body of the first protrusion 2111 protrudes from the side of the arc-shaped hole 232 away from the first rotating member 211. The first protrusion 2111 can slide relative to the arc-shaped hole 232. One end of the first elastic member 215, which is a tension spring, is engaged with the protruding portion of the first protrusion 2111 relative to the arc-shaped hole 232.

[0103] It should be understood that the axis of the first protruding post 2111 is parallel to and spaced apart from the axis of rotation of the first rotating member 211.

[0104] When the first rotating member 211 rotates relative to the bracket 23, the first protrusion 2111 slides relative to the arc-shaped hole 232. By setting the arc-shaped hole 232 and inserting the first protrusion 2111 through the arc-shaped hole 232, the rotation stroke of the first rotating member 211 is limited by the cooperation between the arc-shaped hole 232 and the first protrusion 2111, thereby improving the control accuracy.

[0105] In addition, by utilizing the cooperation between the arc-shaped hole 232 and the first protrusion 2111, the rotation direction of the first rotating member 211 is guided, thereby improving the rotation accuracy of the first rotating member 211.

[0106] It should be noted that the arc-shaped hole 232 can be integrally formed with the bracket 23, or it can be formed by using a tool on the bracket 23.

[0107] In addition, the first protrusion 2111 can be integrally formed with the first rotating part 211, or it can be fixed to the first rotating part 211 by means of bonding, welding, snap-fitting or fastener connection.

[0108] In some embodiments of this application, as shown in Figures 3 to 8, 10, 12 and 14, a second protrusion 231 is provided on the side of the bracket 23 away from the first rotating member 211, and the first end of the first elastic member 215 of the tension spring is engaged with the second protrusion 231 by means of hanging.

[0109] Specifically, the first end of the second elastic element 213 is mounted on the second protrusion 231, which improves the ease of assembly, shortens the assembly time, and thus improves the efficiency of production and processing.

[0110] In some embodiments of this application, as shown in Figures 2, 4, 9, 11 and 13, the first locking mechanism 21 further includes a second elastic member 213. The second elastic member 213 cooperates with the bracket 23 and the limiting member 212 respectively, so that the second elastic member 213 has a second rebound force. Driven by the second rebound force, the limiting member 212 has a tendency to move in the direction of the first rotating member 211 and cooperate with the limiting member 212.

[0111] When the door lock device 300 is used with the cooking appliance 1000, during the process of closing the opening of the cavity 200, the user applies a closing force to the door 100. Under the action of the closing force, the door 100 rotates relative to the cavity 200. The retaining member 10 moves towards the cavity 200 as the door 100 rotates. The first hook 11 first engages with the limiting member 212. During the movement of the first hook 11 relative to the bracket 23, it applies an external force to the limiting member 212, causing the limiting member 212 to overcome the second rebound force of the second elastic member 213 and move away from the first rotating member 211, thereby releasing the restriction on the first rotating member 211. The first elastic force provided by the first elastic element 215 drives the first rotating element 211 to rotate relative to the bracket 23. During the rotation of the first rotating element 211, the first slot 2113 cooperates with the first hook 11 and drives the hook to continue to move relative to the bracket 23 (overcoming the damping force provided by the damping mechanism 22 during the movement). When the first hook 11 moves to the limit position relative to the bracket 23, the first hook 11 is engaged in the first slot 2113, and at the same time the second hook 13 is locked with the second locking mechanism 24, so that the door 100 is kept in the open state of the closed cavity 200.

[0112] When the door 100 is closed and the cavity 200 is closed, if the user needs to open the door 100, by applying an opening force (opposite to the closing force) to the door 100, the second hook 13 unlocks the second locking mechanism 24, and the first hook 11 drives the first slot 2113, causing the first rotating member 211 to rotate in the opposite direction against the first elastic member 215. When the first rotating member 211 returns to its initial state, when the first hook 11 separates from the first slot 2113 and avoids the position of the limiting member 212, the second elastic member 213 drives the limiting member 212 to move closer to the first rotating member 211 and cooperate with the first rotating member 211 again to limit the first rotating member 211, thereby realizing the door opening operation.

[0113] After the holding member 10 separates from the locking assembly 20, a second elastic member 213 is provided, which realizes the automatic limiting of the first rotating member 211 by the limiting member 212, improving the convenience of the user during use.

[0114] It should be noted that the second elastic element 213 can be a compression spring, an elastic sheet, or an elastic rubber component. In this application, the second elastic element 213 is a compression spring, one end of which is sleeved on the protruding structure of the limiting member 212 (the protruding structure is provided on the side of the limiting member 212 facing the compression spring), and the other end of the compression spring abuts against the bracket 23 or is sleeved on the protruding structure of the bracket 23.

[0115] In some embodiments of this application, as shown in Figures 4, 9, 11, and 13, a limiting groove 2121 is formed on the side of the limiting member 212 facing the first rotating member 211, and a limiting protrusion 2114 is provided on the side of the first rotating member 211 facing the limiting member 212. When the holding member 10 separates from the locking assembly 20, the second elastic force of the second elastic member 213 drives the limiting member 212 to abut against the first rotating member 211, and the limiting protrusion 2114 is engaged in the limiting groove 2121. Through the cooperation between the limiting protrusion 2114 and the limiting groove 2121, the first rotating member 211 is limited.

[0116] When the door lock device 300 is used with the cooking appliance 1000, during the process of closing the opening of the cavity 200, the user applies a closing force to the door 100. Under the action of the closing force, the door 100 rotates relative to the cavity 200. The retaining member 10 moves towards the cavity 200 as the door 100 rotates. The first hook 11 first engages with the limiting member 212. During the movement of the first hook 11 relative to the bracket 23, it applies an external force to the limiting member 212, causing the limiting member 212 to overcome the second rebound force of the second elastic member 213 and move away from the first rotating member 211, thereby releasing the limiting of the first rotating member 211. The first hook 11 abuts against... The first elastic force provided by the first elastic element 215, which rests against the limiting protrusion 2114, drives the first rotating element 211 to rotate relative to the bracket 23. During the rotation, the first slot 2113 engages with the first hook 11 and drives the hook to continue moving relative to the bracket 23 (overcoming the damping force provided by the damping mechanism 22 during the movement). When the first hook 11 moves to the limit position relative to the bracket 23, the first hook 11 engages with the first slot 2113, and at the same time, the second hook 13 engages with the second locking mechanism 24, thereby keeping the door 100 in the open state of the closed cavity 200.

[0117] When the door 100 is closed and the cavity 200 is closed, if the user needs to open the door 100, by applying an opening force (opposite to the closing force) to the door 100, the second hook 13 unlocks the second locking mechanism 24, and the first hook 11 drives the first slot 2113, causing the first rotating member 211 to rotate in the opposite direction against the first elastic member 215. When the first rotating member 211 returns to its initial state, when the first hook 11 separates from the first slot 2113 and avoids the position of the limiting member 212, the second elastic member 213 drives the limiting member 212 to move closer to the first rotating member 211, so that the limiting protrusion 2114 is locked into the limiting groove 2121 again to limit the first rotating member 211, thereby realizing the door opening operation.

[0118] The limiting structure formed by the limiting groove 2121 and the limiting protrusion 2114 is relatively simple in structure and can effectively reduce manufacturing costs. At the same time, the limiting structure formed by the limiting groove 2121 and the limiting protrusion 2114 is a concave-convex limiting structure. This kind of limiting structure has a significant limiting effect and can effectively maintain the position of the first rotating part 211.

[0119] It should be noted that the limiting protrusion 2114 is integrally formed on the first rotating member 211 and is disposed adjacent to the first card slot 2113. In this application, the limiting protrusion 2114 is a structure formed by the side wall of the first card slot 2113 protruding from the side away from the card holder 10.

[0120] In some embodiments of this application, as shown in FIG4, the damping mechanism 22 includes a damping member 221 mounted on a bracket 23. The damping member 221 has a movable end, and a first rotating member 211 is tractively connected to the movable end. When switching from the first state to the second state, the damping member 221 is fixed relative to the bracket 23, and the damping member 221 provides damping force to the first locking mechanism 21 to limit the closing speed of the door 100. When switching from the second state to the first state, the damping member 221 moves relative to the bracket 23 and releases the damping force on the first locking mechanism 21.

[0121] Specifically, the damping element 221 provides damping force to the first locking mechanism 21 during the closing action, thereby reducing the closing speed and reducing the noise generated by the door 100 impacting the cavity 200.

[0122] Meanwhile, during the door opening action, the damping mechanism 22 does not generate components in the first locking mechanism 21, thereby reducing the impact on the door opening operation, reducing the force required for the door opening operation, and thus improving the user experience.

[0123] In some embodiments of this application, as shown in Figures 4 to 6, 9, 11, and 13, the damping mechanism 22 further includes a transmission member 222, which is connected to the movable end and the first rotating member 211 respectively. By providing the transmission member 222 and connecting the movable end of the damping member 221 to the first rotating member 211, the transmission of damping force is achieved. This allows for a more reasonable layout of the damping member 221 and the first rotating member 211, resulting in a compact and small door lock device 300 structure, reducing space occupation.

[0124] It should be understood that, under the premise that the damping element 221 is fixed, the movable end can move relative to the damping element 221, and a damping force will be generated when the movable end moves relative to the damping element 221.

[0125] It should be noted that the transmission component 222 can be a linkage mechanism or a gear mechanism, etc.

[0126] In some embodiments of this application, the transmission member 222 is a rack, and continuous teeth 2112 are provided on the outer periphery of the first transmission member 222. The continuous teeth 2112 are arranged along the rotation direction of the first rotating member 211 and mesh with the rack. The transmission member 222 is mounted on the bracket 23 and can move relative to the bracket 23. The movable end of the damping member 221 is connected to the rack, and the moving direction of the rack is consistent with the moving direction of the damping member 221.

[0127] Specifically, continuous teeth 2112 are formed on the outer periphery of the first rotating member 211, covering part or all of the outer periphery of the first rotating member 211. In this application, the continuous teeth 2112 cover a portion of the outer periphery of the first rotating member 211, thereby forming a sector gear structure in the first rotating member 211 that meshes with a rack. This configuration ensures a stable transmission structure, effectively improving transmission accuracy and thus significantly enhancing control precision.

[0128] It should be noted that a sliding groove is provided on the bracket 23, and the transmission component 222 of the rack is slidably disposed in the sliding groove. The sliding groove is used to accommodate and guide the transmission component 222, thereby improving the directionality of the movement of the transmission component 222 and thus improving the control accuracy.

[0129] In some embodiments of this application, as shown in FIG8, a mounting groove 235 is provided on the bracket 23, and a damping element 221 is disposed within the mounting groove 235. The damping element 221 is configured as a damper, which includes a damping rod 2212 and a cylinder 2211. The damping rod 2212 can extend or retract relative to the cylinder 2211, generating a damping force during the extension or retraction process. The end of the damping rod 2212 facing away from the cylinder 2211 is a movable end and is connected to a geared transmission element 222.

[0130] As shown in Figures 3 and 4, the locking assembly 20 in this application also includes a cover plate 25, which cooperates with the bracket to close the opening of the mounting groove 235, thereby isolating the damping element 221 from the outside world and reducing the possibility of the damping element 221 coming out and the adverse effects of the outside world on the damping element 221.

[0131] When the door is closed (the first locking mechanism 21 switches from the first state to the second state), the first rotating member 211 rotates relative to the bracket 23, and the continuous tooth 2112 drives the rack to move relative to the bracket 23. The rack drives the telescopic rod to retract relative to the cylinder 2211 through the movable end. The cylinder 2211 abuts against the side wall of the mounting groove 235 away from the movable end and provides damping force to the first locking mechanism 21 to limit the closing speed of the door 100. When the door is opened (the first locking mechanism 21 switches from the second state to the first state), the rack drives the cylinder 2211 to move relative to the mounting groove 235 through the movable end and releases the damping force on the first locking mechanism 21.

[0132] By setting the damping element 221, a damping force is achieved during the closing operation to reduce the closing speed and reduce the closing impact noise, and no damping force is achieved during the opening operation to reduce the opening force, thereby improving the user's comfort during use.

[0133] In some embodiments of this application, as shown in Figures 2 to 4 and Figures 9 to 14, the first locking mechanism 21 further includes a first detection element 214 mounted on the bracket 23. When the door 100 is closed, the first hook 11 engages with the first slot 2113, the second hook 13 is locked with the second locking mechanism 24, and the first rotating element 211 triggers the first detection element 214.

[0134] Specifically, a first working surface 2115 is provided on the outer peripheral surface of the first rotating member 211. When the door 100 is closed, the first rotating member 211 rotates relative to the bracket 23, causing the first hook 11 to engage with the first slot 2113. The first working surface 2115 rotates to the position of the first detection member 214 and triggers the first detection member 214. The first detection member 214 sends a detection signal to the cooking appliance 1000. At this time, the cooking appliance 1000 determines that the closing action is completed based on the received signal. When the door is opened, the first rotating member 211 rotates in the opposite direction, the first working surface 2115 separates from the first detection member 214, and the triggering of the first detection member 214 is released. At this time, the cooking appliance 1000 does not receive a signal, thus determining that the door 100 is open.

[0135] By setting the first detection element 214, the closed state can be effectively detected, thereby improving the control accuracy.

[0136] It should be noted that the first detection element 214 can be a contact switch or a position sensor, etc.

[0137] In some embodiments of this application, as shown in Figures 2, 4, 9, 11 and 13, the second locking mechanism 24 includes a second rotating member 241 rotatably disposed on the bracket 23. When the door 100 is closed, the second hook 13 engages with the second slot of the second rotating member 241.

[0138] When the door lock device 300 is used with the cooking appliance 1000, during the process of closing the opening of the cavity 200, the user applies a closing force to the door 100. Under the action of the closing force, the door 100 rotates relative to the cavity 200. The latching member 10 moves towards the cavity 200 as the door 100 rotates. The first latch 11 first engages with the limiting member 212. During the movement of the first latch 11 relative to the bracket 23, it applies an external force to the limiting member 212, causing the limiting member 212 to overcome the second rebound force of the second elastic member 213 and move away from the first rotating member 211, thereby releasing the limiting of the first rotating member 211. The first latch 11 abuts against the limiting protrusion 2114, and the first elastic member 211... The first rebound force provided by 15 drives the first rotating member 211, causing the first rotating member 211 to rotate relative to the bracket 23. During the rotation of the first rotating member 211, the first slot 2113 cooperates with the first hook 11 and drives the hook to continue to move relative to the bracket 23 (overcoming the damping force provided by the damping mechanism 22 during the movement). At this time, the second hook 13 drives the second rotating member 241 to rotate relative to the bracket 23. When the first hook 11 moves to the limit position relative to the bracket 23, the second hook 13 also reaches the limit position. The first hook 11 is engaged in the first slot 2113, and the second hook 13 is engaged in the second slot, thereby keeping the door body 100 in the open state of the closed cavity 200.

[0139] When the door 100 is in the closed state of the cavity 200, and the user needs to open the door 100, by applying an opening force to the door 100 (in the opposite direction to the closing force), the second hook 13 separates from the second slot, and the first hook 11 drives the first slot 2113, causing the first rotating member 211 to rotate in the opposite direction against the first elastic member 215. When the first rotating member 211 returns to its initial state, when the first hook 11 separates from the first slot 2113 and avoids the position of the limiting member 212, the second elastic member 213 drives the limiting member 212 to move closer to the first rotating member 211, so that the limiting protrusion 2114 is once again engaged in the limiting groove 2121 to limit the first rotating member 211, thereby realizing the door opening operation.

[0140] By setting the second rotating member 241, an effective cooperation with the second hook 13 is achieved, thereby improving the locking effect on the door 100.

[0141] It should be noted that a second mounting post 237 (which can be integrally formed with the bracket 23, for example) is provided on the bracket 23, and a second mounting hole is provided on the second rotating member 241. The second mounting post 237 is inserted into the second mounting hole, and a second limiting member is provided at the end of the second mounting post 237 protruding from the second mounting hole, thereby realizing the rotatable connection between the second rotating member 241 and the bracket 23. This structure is simple, can effectively reduce manufacturing costs, and is easy to assemble, thus effectively improving assembly efficiency.

[0142] A second slot is provided on the second rotating member 241, and a second retainer is provided on the outer peripheral wall of the first rotating member 211. The second slot is used to cooperate with the second hook 13.

[0143] In some embodiments of this application, as shown in Figures 2, 4, 9, 11 and 13, the second locking mechanism 24 further includes a second detection element 243 mounted on the bracket 23. When the door 100 is closed, the second hook 13 engages with the second slot, and the second rotating element 241 triggers the second detection element 243.

[0144] Specifically, a second working surface is provided on the outer peripheral surface of the second rotating member 241. When the door 100 is closed, the second rotating member 241 rotates relative to the bracket 23, causing the second hook 13 to engage with the second slot. The second working surface rotates to the position of the second detection member 243 and triggers the second detection member 243. The second detection member 243 sends a detection signal to the cooking appliance 1000. At this time, the cooking appliance 1000 determines that the closing action is completed based on the received signal. When the door is opened, the second rotating member 241 rotates in the opposite direction, the second working surface separates from the second detection member 243, and the triggering of the second detection member 243 is released. At this time, the cooking appliance 1000 does not receive a signal, thus determining that the door 100 is open.

[0145] By setting the second detection element 243, the closed state can be effectively detected, thereby improving the control accuracy.

[0146] It should be noted that the second detection element 243 can be a contact switch or a position sensor, etc.

[0147] In some embodiments of this application, as shown in Figures 2, 4, 9, 11, and 13, the second locking mechanism 24 further includes a third elastic element 242. The third elastic element 242 cooperates with the second rotating element 241 and the bracket 23 respectively. The third elastic element 242 has a critical position and a third rebound force. When the second hook 13 is not engaged in the second slot, the third rebound force drives the second rotating element 241 to rotate in a first direction. When the second hook 13 is engaged in the second slot and passes the critical position, the third rebound force drives the second rotating element 241 to rotate in a second direction. The first direction is opposite to the second direction.

[0148] When the door lock device 300 is used with the cooking appliance 1000, during the process of closing the opening of the cavity 200, the user applies a closing force to the door 100. Under the action of the closing force, the door 100 rotates relative to the cavity 200. The latching member 10 moves towards the cavity 200 as the door 100 rotates. The first latch 11 first engages with the limiting member 212. During the movement of the first latch 11 relative to the bracket 23, it applies an external force to the limiting member 212, causing the limiting member 212 to overcome the second rebound force of the second elastic member 213 and move away from the first rotating member 211, thereby releasing the limiting of the first rotating member 211. The first latch 11 abuts against the limiting protrusion 2114, and the first elastic member... The first rebound force provided by 215 drives the first rotating member 211, causing it to rotate relative to the bracket 23. During rotation, the first slot 2113 engages with the first hook 11, driving the hook to continue moving relative to the bracket 23 (overcoming the damping force provided by the damping mechanism 22 during the movement). The second hook 13 drives the second rotating member 241 to overcome the third rebound force of the third elastic member 242 and rotate relative to the bracket 23 in the second direction. When the third elastic member 242 passes the critical position, the third rebound force of the third elastic member 242 drives the second rotating member 241 to rotate relative to the bracket 23 in the second direction, and the second slot drives the second hook 13 to move synchronously. When the first hook 11 moves to the limit position relative to the bracket 23, the second hook 13 also reaches the limit position. The first hook 11 engages with the first slot 2113, and the second hook 13 engages with the second slot, thereby keeping the door 100 in the open state of the closed cavity 200.

[0149] With the door 100 closed and the cavity 200 open, when the user needs to open the door 100, by applying an opening force (opposite to the closing force) to the door 100, the second hook 13 drives the second slot to rotate in the first direction against the third elastic force of the third elastic member 242. When the third elastic member 242 passes the critical position, the third elastic force of the third elastic member 242 drives the second rotating member 241 to rotate in the first direction and reset. The second hook 13 separates from the first hook 11, and the first hook 11 engages with the first slot. Driven by 2113, the first rotating member 211 rotates in the opposite direction against the first elastic force of the first elastic member 215. When the first rotating member 211 returns to its initial state, when the first hook 11 separates from the first slot 2113 and avoids the position of the limiting member 212, the second elastic force of the second elastic member 213 drives the limiting member 212 to move closer to the first rotating member 211, so that the limiting protrusion 2114 is once again inserted into the limiting groove 2121 to limit the first rotating member 211, thereby realizing the door opening operation.

[0150] By setting a third elastic element 242, the second locking and automatic reset of the second hook 13 with the second rotating element 241 are achieved, which improves the convenience of the user.

[0151] It should be noted that in this application, the third elastic element 242 is a torsion spring.

[0152] As shown in Figures 1 to 14, a second aspect of this application provides a cooking appliance 1000, which includes a cavity 200, a door 100, and a door lock device 300 according to the above. The cavity 200 includes an opening, and the door 100 is pivotally connected to the cavity 200 and used to open or close the opening. The latching member 10 of the door lock device 300 is installed on the door 100, and the bracket 23 of the locking assembly 20 of the door lock device 300 is installed on the cavity 200 and located on one side of the opening.

[0153] According to the cooking appliance 1000 of this application, an external force drives the door 100 to close the opening of the cavity 200. The closing force acts on the door 100, causing the first hook 11 to engage with the first locking mechanism 21. When the first locking mechanism 21 switches from the first state to the second state, the closing force can be released. The first locking mechanism 21 engages with the first hook 11 to drive the first hook 11 to move relative to the bracket 23 until the first hook 11 engages with the first locking mechanism 21 and the second hook 13 engages with the second locking mechanism 24.

[0154] The first locking mechanism 21 is used to drive the first hook 11 to move relative to the bracket 23, which realizes the locking of the first hook 11 with the first locking mechanism 21 and the cooperation of the second hook 13 with the second locking mechanism 24. This reduces the closing force applied when the door 100 is closed. At the same time, the damping force generated by the damping mechanism 22 can slow down the closing speed, thereby reducing the impact of the door 100 on the cavity 200, and thus improving the user experience.

[0155] The cooking appliance mentioned above can be an oven or a cooking appliance with microwave cooking function. In this application, the cooking appliance mentioned above is a cooking appliance with microwave cooking function. For the structure of other parts of the cooking appliance with microwave cooking function, please refer to the prior art. It will not be described again in this application.

[0156] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
