[0002] In the related art, a cooking appliance comprises a cavity and a door, wherein the door is rotatably mounted on the cavity, and the door can open or close the opening of the cavity under the action of an external force and be locked by a door locking device.

[0003] However, during the process of closing the door, a large external force needs to be applied to the door. At the same time, the door is prone to hit the cavity and make a large noise during the closing process, thereby reducing the user experience. Utility Model Content

[0004] The purpose of this application is to at least solve the problem of how to reduce the external force when closing the door and the problem of the door body hitting the cavity. This purpose is achieved through the following technical solutions:

[0005] A first aspect of the present application provides a door lock device for a cooking appliance, wherein the cooking appliance comprises a door body and a cavity having an opening, wherein the door body is pivotally connected to the cavity and is used to open or close the opening, and the door lock device comprises:

[0007] The locking assembly includes a bracket, and a first locking mechanism, a second locking mechanism and a damping mechanism respectively installed on the bracket, the bracket is used to be installed in 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 to each other, the closing force drives the first hook to cooperate with the first locking mechanism, so that the first hook moves relative to the bracket to switch the first locking mechanism 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 overcome the resistance of the damping mechanism and move, so that the first hook is locked with the first locking mechanism and the second hook is locked with the second locking mechanism.

[0008] When the door lock device described in the present application is used for a cooking appliance, an external force drives the door body to close the opening of the cavity. The door closing force acts on the door body, causing the first hook to cooperate with the first locking mechanism first. When the first locking mechanism switches from the first state to the second state, the door closing force can be released, and the first locking mechanism cooperates with the first hook to drive the first hook to move relative to the bracket until the first hook is locked with the first locking mechanism and the second hook is locked with the second locking mechanism.

[0009] The first locking mechanism is used to drive the first hook to move relative to the bracket, so that the first hook is locked with the first locking mechanism and the second hook cooperates with the second locking mechanism, reducing 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 situation where the door hits the cavity, thereby improving the user experience.

[0021] In some embodiments of the present application, the damping mechanism includes a damping member, which is installed on the bracket. The damping member includes a movable end, which is transmission-connected to the first rotating member.

Thus, the example term "below" can encompass both above and below orientations.

[0069] like Figures 1 to 14 As shown, according to an embodiment of the present application, a door lock device 300 for a cooking appliance 1000 is proposed, wherein the cooking appliance 1000 includes a cavity 200 and a door body 100, the cavity 200 has an opening, and the cooking cavity in the cavity 200 is connected to the outside world through the opening, the door body 100 is connected to the cavity 200 and can pivot relative to the cavity 200, and the door body 100 pivots relative to the cavity 200 to perform the operation of opening or closing the opening of the cavity 200.

[0070] In the present application, the door lock device 300 includes a locking assembly 20 and a retaining member 10, wherein the retaining member 10 is mounted and fixed on the door body 100, and the locking assembly 20 is mounted and fixed 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 and the door lock device 300 are locked. When the door body 100 opens the opening of the cavity 200, the retaining member 10 and the door lock device 300 are unlocked.

[0071] In some embodiments of the present application, Figures 2 to 4 ,as well as Figures 9 to 14As shown, the clamping 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 and spaced apart.

[0072] In some embodiments of the present application, the volume of the first hook 11 is greater than the volume of the second hook 13 .

[0073] It should be understood that the first hook 11 includes a first hook portion having a first opening, and the second hook 13 includes a second hook portion having a second opening. The openings of the first hook 11 and the second hook 13 are arranged in opposite directions, meaning that the first opening and the second opening are opposite, opposite, or aligned.

[0074] In addition, in the present application, when the holder 10 cooperates with the locking assembly 20, the holder 10 has a moving direction. In the moving direction of the holder 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.

[0075] In addition, when the holding member 10 is locked with the locking component 20, since the length of the first hook 11 is greater than the length of the second hook 13, the first hook 11 first cooperates with the locking component 20. When the first hook 11 moves a distance relative to the locking component 20, the second hook 13 cooperates with the locking component 20 again, and finally the first hook 11 and the second hook 13 are respectively locked with the locking component 20, thereby achieving the door body 100 remaining in the state of closing the opening of the cavity 200.

[0076] For another example, along a first direction, the size of the first hook 11 is greater than the size of the second hook 13 , wherein the first direction is the length direction of the cavity 200 .

[0077] By setting 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 body 100, and the size of the second socket 234 on the bracket for the second hook 13 to pass through can be reduced, so that foreign objects cannot enter the interior of the locking component through the second socket 234, further reducing the failure rate of the door lock device 300.

[0078] It should be understood that in the present application, when the user faces the cooking appliance 1000 in a placed state, the direction of the left and right sides of the cooking appliance 1000 is the length direction of the cooking appliance 1000, that is, the length direction of the cavity 200.

[0079] For another example, along the second direction, the size of the first hook 11 is greater than the size of the second hook 13 , wherein the second direction is the height direction of the cavity 200 .

[0080] By setting 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 body 100, and the size of the second socket 234 on the bracket for the second hook 13 to pass through can be reduced, so that foreign objects cannot enter the interior of the locking component through the second socket 234, further reducing the failure rate of the door lock device 300.

[0081] It should be understood that, in the present application, when the user faces the cooking appliance 1000 in a 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, that is, the height of the cavity 200.

[0082] In some embodiments of the present application, Figures 2 to 4 ,as well as Figures 7 to 14 As shown, 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 installed 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 transmission-connected to the first locking mechanism 21. The first locking mechanism 21 is arranged opposite to the first hook 11, and the second locking mechanism 24 is arranged opposite to the second hook 13.

[0083] The first locking mechanism 21 includes a first state and a second state, and the first state and the second state are switchable between each other. When the clamping member 10 is locked to the locking member, the first hook 11 cooperates with the first locking mechanism 21, causing the first locking mechanism 21 to switch from the first state to the second state, and the first hook 11 and the first locking mechanism 21 are locked in the second state.

[0084] When the door lock device 300 is used in the cooking appliance 1000, when the user is closing the opening of the cavity 200, the user applies a closing force to the door body 100. Under the action of the closing force, the door body 100 rotates relative to the cavity 200, and the holding member 10 moves toward the cavity 200 as the door body 100 rotates. The first hook 11 first cooperates with the first locking mechanism 21. Driven by the closing force, the hook moves relative to the bracket 23 and drives the first locking mechanism 21. Driven by the first hook 11, the first locking mechanism 21 switches from the first state to the second state. In the second state, the damping mechanism 22 provides a damping force to the first locking mechanism 21. The damping force acts on the first hook 11 through the first locking mechanism 21. The direction of the damping force is opposite to the movement direction of the first hook 11 relative to the bracket 23. Under the action of the damping force, the movement speed of the first hook 11 relative to the bracket 23 is reduced, thereby reducing the collision between the door body 100 and the cavity 200.

[0085] When the first locking mechanism 21 switches from the first state to the second state, the user releases the door closing force, and the first locking mechanism 21 cooperates with the first hook 11 and provides a driving force for the first hook 11. Driven by the driving force, the first locking mechanism 21 drives the first hook 11 to continue to move relative to the bracket 23 until the first hook 11 and the first locking mechanism 21 are locked in place (i.e., locked). In 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.

[0086] When the door body 100 closes the opening of the cavity 200, when the user needs to open the door body 100, by applying a door-opening force (opposite to the direction of the door-closing force) to the door body 100, the first locking mechanism 21 and the first hook 11 are unlocked, 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 unlocked, thereby realizing the door opening operation.

[0087] It should be understood that the locking of the first hook 11 and 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 limit the position of the first hook 11, that is, the first hook 11 is in a locked state; similarly, the locking of the second hook 13 and 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 limit the position of the second hook 13, that is, the second hook 13 is in a locked state.

[0088] When the door lock device 300 of the present 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 door closing force acts on the door body 100, so that the first hook 11 first cooperates with the first locking mechanism 21. When the first locking mechanism 21 switches from the first state to the second state, the door closing force can be released, and the first locking mechanism 21 cooperates with the first hook 11 to drive the first hook 11 to move relative to the bracket 23 until the first hook 11 is locked with the first locking mechanism 21 and the second hook 13 cooperates 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, so that the first hook 11 is locked with the first locking mechanism 21 and the second hook 13 cooperates with the second locking mechanism 24, reducing the closing force applied when the door body 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 situation where the door body 100 hits the cavity 200, thereby improving the user experience.

[0089] It should be pointed out that in the present application, the bracket 23 has a snap-in end, which is arranged facing the holder 10, and the first locking mechanism 21, the second locking mechanism 24 and the damping mechanism 22 are respectively arranged on the bracket 23, and the snap-in end includes a second socket 233 and a second socket 234 arranged at intervals. The second socket 233 is arranged opposite to the first hook 11, and the second socket 234 is arranged opposite to the second hook 13. The first locking mechanism 21 is correspondingly arranged on the side of the snap-in end away from the holder 10, and the second locking mechanism 24 is correspondingly arranged on the side of the snap-in end away from the holder 10.

[0090] When the holder 10 is engaged with the locking assembly 20 , the first hook 11 is inserted into the bracket 23 from the second insertion hole 233 and locked with the first locking mechanism 21 , and the second hook 13 is inserted into the bracket 23 from the second insertion hole 234 and locked with the second locking mechanism 24 .

[0091] The bracket 23 is an integrated structure. The integrated bracket 23 can be processed and manufactured by stamping, die-casting, injection molding or pouring, which reduces the processing steps and improves the processing efficiency. At the same time, the integrated 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 fully exert their performance, thereby reducing the failure rate of the door lock device 300.

[0092] In addition, the holding member 10 also includes a mounting portion 12, and the first hook 11 and the second hook 13 are respectively arranged on the mounting portion 12, wherein the first hook 11 and the mounting portion 12 can be an integral structure or a split structure, and the second hook 13 and the mounting portion 12 can be an integral structure or a split structure.

[0093] When the mounting portion 12, the first hook 11, and the second hook 13 are of a split-type structure, the first hook 11 can be fixed to the mounting portion 12 by bonding, welding, clamping, or connecting with fasteners. Similarly, the second hook 13 can also be fixed to the mounting portion 12 by bonding, welding, clamping, or connecting with fasteners. The mounting portion 12, the first hook 11, and the second hook 13 are of a split-type structure, and the materials of the three can be completely the same, partially the same, or completely different. For example, the mounting portion 12 is a plastic part, the first hook 11 is a metal part, and the second hook 13 is also a metal part. The first hook 11 and the second hook 13, which are metal parts, are fixed to the mounting portion 12 by fasteners such as screws.

[0094] When the mounting portion 12, the first hook 11 and the second hook 13 are an integrated structure, they can be processed and manufactured by stamping, die-casting, injection molding or pouring, which reduces the processing steps and improves the processing efficiency. At the same time, the structural strength of the integrated structure of the holder 10 is high, 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.

[0095] In some embodiments of the present application, Figures 2 to 4 ,as well as Figures 9 to 14 As shown, the first locking mechanism 21 includes a first rotating member 211 , a limiting member 212 and a first elastic member 215 .

[0096] Specifically, the first rotating member 211 is mounted on the bracket 23 and can rotate relative to the bracket 23. When the clamping member 10 cooperates with the locking assembly 20, the clamping 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.

[0097] A first mounting post 236 is provided on the bracket 23 (e.g., it can be integrally formed with the bracket 23). A first mounting hole 2116 is formed on the first rotating member 211. The first mounting post 236 is inserted into the first mounting hole 2116. A first stopper is provided at one end of the first mounting post 236 that protrudes from the first mounting hole 2116, thereby achieving a rotatable connection between the first rotating member 211 and the bracket 23. This simple structure can effectively reduce manufacturing costs, facilitate assembly, and effectively improve assembly efficiency.

[0098] The first rotating member 211 is provided with a first latching groove 2113 . The first latching groove 2113 is provided on the outer peripheral wall of the first rotating member 211 . The first latching groove 2113 is used to cooperate with the first hook 11 .

[0099] The limit member 212 is installed on the bracket 23, and the limit member 212 can rotate relative to the bracket 23. When the clamping member 10 is separated from the locking assembly 20, the limit member 212 cooperates with the first rotating member 211 to limit (the cooperation between the first rotating member 211 and the limit can be separated). Under the action of the limit member 212, the first rotating member 211 cannot rotate relative to the bracket 23.

[0100] The first elastic member 215 cooperates with the first rotating member 211 and the bracket 23 respectively. The first elastic member 215 is in a stretched state. The first elastic member 215 in the stretched state has a first rebound force. The first rebound force makes the first rotating member 211 have a tendency to rotate. Driven by the first rebound force, the first locking mechanism 21 has a tendency to switch from the first state to the second state.

[0101] When the door lock device 300 is used for the cooking appliance 1000, the user applies a closing force to the door body 100 during the process of closing the opening of the cavity 200. Under the action of the closing force, the door body 100 rotates relative to the cavity 200, and the holding member 10 moves toward the direction close to the cavity 200 as the door body 100 rotates. The first hook 11 first cooperates with the limiting member 212. During the movement of the first hook 11 relative to the bracket 23, an external force is applied to the limiting member 212, causing the limiting member 212 to move in the direction away from the first rotating member 211, so that the limiting member 212 releases the limit on the first rotating member 211, and the first spring The first rebound force provided by the elastic member 215 drives the first rotating member 211, so that the first rotating member 211 rotates 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). When the first hook 11 moves to the extreme position relative to the bracket 23, the first hook 11 is locked into 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 body 100 remains in a state of closing the opening of the cavity 200.

[0102] When the door body 100 closes the opening of the cavity 200, when the user needs to open the door body 100, by applying a door-opening force (opposite to the direction of the door-closing force) to the door body 100, the second hook 13 and the second locking mechanism 24 are unlocked, and the first hook 11 drives the first slot 2113, so that the first rotating member 211 overcomes the first rebound force of the first elastic member 215 and rotates in the opposite direction. When the first rotating member 211 is reset to the initial state, when the first hook 11 separates from the first slot 2113 and avoids the position of the limit member 212, the limit member 212 cooperates with the first rotating member 211 again to limit the first rotating member 211, thereby realizing the door opening operation.

[0103] The limiting member 212 is used to limit the first rotating member 211, so that the first rotating member 211 has a tendency to switch to the second state. When closing the door, the user only needs to use a small force to drive the limiting member 212 to release the limit on the first rotating member 211. After the limit is released, the first rotating member 211 can drive the first hook 11. Under the premise that the user does not apply any external force, the first rotating member 211 can lock the holding member 10 and the locking component 20 by driving the first hook 11 to move, thereby effectively reducing the closing force of the user when closing the door, so that the user experience is effectively improved.

[0104] It is necessary to support that the first elastic member 215 is in a stretched state, wherein the first elastic member 215 includes but is not limited to an elastic rope and a tension spring.

[0105] In some embodiments of the present application, Figure 3 and Figure 4 As shown, the first elastic member 215 is configured as a tension spring, which includes a first end and a second end that are oppositely arranged, wherein the first end of the tension spring cooperates with the bracket 23 in a hanging manner, and the second end of the tension spring cooperates with the first rotating member 211 in a hanging manner.

[0106] The first elastic member 215 is configured as a tension spring, which can provide a continuous and stable first rebound force for the first rotating member 211 , thereby reducing plastic deformation due to long-term use, thereby reducing the failure rate of the door lock device 300 .

[0107] 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.

[0108] In addition, the wide range of materials for tension springs can effectively reduce the cost of manufacturing, maintenance and replacement.

[0109] It should be pointed out that a first hanging hole or a first protrusion can be set on the bracket 23, and the first end of the tension spring can be hung and matched with the first hanging hole or the first protrusion. A second hanging hole or a second protrusion can be set on the first rotating part 211, and the second end of the tension spring can be hung and matched with the second hanging hole or the second protrusion.

[0110] In addition, the tension spring and the first rotating member 211 can be arranged on the same side of the bracket 23, or on opposite sides.

[0111] In some embodiments of the present application, Figure 3 and Figure 4 As shown, 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.

[0112] In some embodiments of the present application, Figures 3 to 8 、 Figure 10 、 Figure 12 as well as Figure 14 As shown, the first rotating member 211 is installed on the bracket 23 and can rotate relative to the bracket 23. An arc-shaped hole 232 extending along the rotation direction of the first rotating member 211 is provided on the bracket 23. The first rotating member 211 includes a first boss 2111 passing through the arc-shaped hole 232. Part of the body of the first boss 2111 protrudes and is arranged on the side of the arc-shaped hole 232 away from the first rotating member 211. The first boss 2111 can slide relative to the arc-shaped hole 232. One end of the first elastic member 215 which is a tension spring is hung and cooperated with the part of the first boss 2111 protruding relative to the arc-shaped hole 232.

[0113] It should be understood that the axis of the first protruding column 2111 is parallel to and spaced from the rotation axis of the first rotating member 211 .

[0114] When the first rotating member 211 rotates relative to the bracket 23, the first protrusion 2111 slides relative to the arc-shaped hole 232. The arc-shaped hole 232 is provided, and the first protrusion 2111 is inserted into the arc-shaped hole 232. The arc-shaped hole 232 cooperates with the first protrusion 2111 to limit the rotational travel of the first rotating member 211, thereby improving control accuracy.

[0115] In addition, the arc-shaped hole 232 cooperates with the first protruding column 2111 to guide the rotation direction of the first rotating member 211, thereby improving the rotation accuracy of the first rotating member 211.

[0116] It should be noted that the arc-shaped hole 232 can be integrally formed with the bracket 23 , or can be formed on the bracket 23 using a tool.

[0117] In addition, the first protruding column 2111 can be integrally formed with the first rotating member 211 , or can be fixed to the first rotating member 211 by bonding, welding, clamping, or connecting with fasteners.

[0118] In some embodiments of the present application, Figures 3 to 8 、 Figure 10 、 Figure 12 as well as Figure 14 As shown, 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 , which is a tension spring, is engaged with the second protrusion 231 in a hanging manner.

[0119] Specifically, the first end of the second elastic member 213 is mounted on the second protruding column 231 , thereby improving the convenience of assembly, shortening the assembly time, and further improving the efficiency of production and processing.

[0120] In some embodiments of the present application, Figure 2 、 Figure 4 、 Figure 9 、 Figure 11 as well as Figure 13 As shown, the first locking mechanism 21 also includes a second elastic member 213, which 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.

[0121] When the door lock device 300 is used for the cooking appliance 1000, the user applies a closing force to the door body 100 during the process of closing the opening of the cavity 200. Under the action of the closing force, the door body 100 rotates relative to the cavity 200, and the holding member 10 moves toward the direction close to the cavity 200 as the door body 100 rotates. The first hook 11 first cooperates with the limiting member 212. During the movement of the first hook 11 relative to the bracket 23, an external force is applied to the limiting member 212, so that the limiting member 212 overcomes the second rebound force of the second elastic member 213 and moves in the direction away from the first rotating member 211, so that the limiting member 212 is released. The first elastic member 215 is in the position, and the first rebound force provided by the first elastic member 215 drives the first rotating member 211, so that the first rotating member 211 rotates 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). When the first hook 11 moves to the extreme position relative to the bracket 23, the first hook 11 is locked in the first slot 2113, and the second hook 13 is locked with the second locking mechanism 24, so that the door body 100 remains in the state of closing the opening of the cavity 200.

[0122] When the door body 100 closes the opening of the cavity 200, when the user needs to open the door body 100, by applying a door-opening force (opposite to the direction of the door-closing force) to the door body 100, the second hook 13 and the second locking mechanism 24 are unlocked, and the first hook 11 drives the first slot 2113, so that the first rotating member 211 overcomes the first rebound force of the first elastic member 215 and rotates in the opposite direction. When the first rotating member 211 is reset to the initial state, when the first hook 11 separates from the first slot 2113 and avoids the position of the limit member 212, the second rebound force of the second elastic member 213 drives the limit member 212 to move in the direction close 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.

[0123] When the holding member 10 is separated from the locking assembly 20 , the second elastic member 213 is provided to realize automatic position limiting of the first rotating member 211 by the limiting member 212 , thereby improving the convenience of the user during use.

[0124] It should be noted that the second elastic member 213 can be a compression spring, an elastic sheet, or elastic rubber. In the present application, the second elastic member 213 is a compression spring, one end of which is sleeved on the protrusion of the stopper 212 (the protrusion is provided on the side of the stopper 212 facing the compression spring), and the other end of the compression spring abuts against the bracket 23 or is sleeved on the protrusion of the bracket 23.

[0125] In some embodiments of the present application, Figure 4 、 Figure 9、 Figure 11 as well as Figure 13 As shown, a limiting groove 2121 is defined 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 retaining member 10 is separated from the locking assembly 20, the second rebound force of the second elastic member 213 drives the limiting member 212 into contact with the first rotating member 211, and the limiting protrusion 2114 is locked 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.

[0126] When the door lock device 300 is used for the cooking appliance 1000, the user applies a closing force to the door body 100 during the process of closing the opening of the cavity 200. Under the action of the closing force, the door body 100 rotates relative to the cavity 200, and the holding member 10 moves toward the direction close to the cavity 200 as the door body 100 rotates. The first hook 11 first cooperates with the limiting member 212. During the movement of the first hook 11 relative to the bracket 23, an external force is applied to the limiting member 212, so that the limiting member 212 overcomes the second rebound force of the second elastic member 213 and moves in the direction away from the first rotating member 211, so that the limit on the first rotating member 211 is released. The first hook 11 hits the Leaning on the limiting protrusion 2114, the first rebound force provided by the first elastic member 215 drives the first rotating member 211, so that the first rotating member 211 rotates 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). When the first hook 11 moves to the extreme position relative to the bracket 23, the first hook 11 is locked into 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 body 100 remains in a state of closing the opening of the cavity 200.

[0127] When the door body 100 closes the opening of the cavity 200, when the user needs to open the door body 100, by applying a door opening force (opposite to the direction of the door closing force) to the door body 100, the second hook 13 and the second locking mechanism 24 are unlocked, and the first hook 11 drives the first slot 2113, so that the first rotating member 211 overcomes the first rebound force of the first elastic member 215 and rotates in the opposite direction. When the first rotating member 211 is reset to the initial state, when the first hook 11 separates from the first slot 2113 and avoids the position of the limit member 212, the second rebound force of the second elastic member 213 drives the limit member 212 to move in the direction close to the first rotating member 211, so that the limit protrusion 2114 is again locked in the limit slot 2121 to limit the first rotating member 211, thereby realizing the door opening operation.

[0128] The limiting structure formed by the limiting groove 2121 and the limiting protrusion 2114 is relatively simple in structure and can effectively reduce the manufacturing cost. At the same time, the limiting structure formed by the limiting groove 2121 and the limiting protrusion 2114 is a concave-convex limiting structure. The limiting effect of this limiting structure is obvious and can effectively maintain the position of the first rotating part 211.

[0129] It should be pointed out that the limiting protrusion 2114 is integrally formed on the first rotating member 211 and is arranged adjacent to the first clamping groove 2113. In the present application, the limiting protrusion 2114 is a structure formed by the side wall protruding from the side of the first clamping groove 2113 away from the clamping member 10.

[0130] In some embodiments of the present application, Figure 4 As shown, the damping mechanism 22 includes a damping member 221 mounted on the bracket 23, the damping member 221 has a movable end, and the first rotating member 211 is transmission-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 a damping force for the first locking mechanism 21 to limit the closing speed of the door body 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.

[0131] Specifically, the damping member 221 provides a damping force to the first locking mechanism 21 during the door closing action, so that the door closing speed is reduced, thereby reducing the noise generated by the door body 100 hitting the cavity 200.

[0132] At the same time, when the door is opened, the damping mechanism 22 does not produce components on the first locking mechanism 21, thereby reducing the impact on the door opening operation, reducing the force required during the door opening operation, and thus improving the user experience.

[0133] In some embodiments of the present application, Figures 4 to 6 、 Figure 9 、 Figure 11 as well as Figure 13 As shown, the damping mechanism 22 further includes a transmission member 222, which is respectively in transmission connection with the movable end and the first rotating member 211. The transmission member 222 is provided, and the movable end of the damping member 221 is transmission-connected to the first rotating member 211 via the transmission member 222, thereby achieving transmission of the damping force, allowing for a reasonable layout of the damping member 221 and the first rotating member 211, thereby making the door lock device 300 compact and compact, and reducing space occupation.

[0134] It should be understood that, under the premise that the damping member 221 is fixed, the movable end can move relative to the damping member 221 , and a damping force will be generated when the movable end moves relative to the damping member 221 .

[0135] It should be noted that the transmission member 222 can be a connecting rod mechanism or a gear mechanism, etc.

[0136] In some embodiments of the present application, the transmission member 222 is a rack, and continuous teeth 2112 are arranged on the outer peripheral side of the first transmission member 222. The continuous teeth 2112 are arranged along the rotation direction of the first rotating member 211 and are engaged with the rack. The transmission member 222 is arranged 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.

[0137] Specifically, continuous teeth 2112 are formed on the outer periphery of the first rotating member 211, partially or entirely covering the outer periphery of the first rotating member 211. In the present application, the continuous teeth 2112 partially cover the outer periphery of the first rotating member 211, thereby forming a sector gear structure on the first rotating member 211 and meshing with the rack. This arrangement stabilizes the transmission structure, effectively improving transmission accuracy and control precision.

[0138] It should be pointed out that a slide groove is provided on the bracket 23, and the transmission member 222 of the rack is set in the slide groove in a sliding manner. The slide groove is used to accommodate and guide the transmission member 222, thereby improving the directionality of the movement of the transmission member 222 and thus improving the control accuracy.

[0139] In some embodiments of the present application, Figure 8 As shown, a mounting groove 235 is provided on the bracket 23, and a damping member 221 is disposed within the mounting groove 235. The damping member 221 is configured as a damper, comprising a damping rod 2212 and a cylinder 2211. The damping rod 2212 can extend or retract relative to the cylinder 2211, and a damping force is generated during the extension or retraction of the damping rod 2212 relative to the cylinder 2211. The end of the damping rod 2212 facing away from the cylinder 2211 is a movable end and is connected to a transmission member 222, which is a rack.

[0140] In this application, if Figure 3 and Figure 4 As shown, the locking assembly 20 also includes a cover plate 25, which cooperates with the bracket to close the slot of the installation slot 235, thereby isolating the damping member 221 from the outside world, reducing the damping member 221 from falling out and the adverse effects of the outside world on the damping member 221.

[0141] 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 teeth 2112 drive the rack to move relative to the bracket 23. The rack drives the telescopic rod to retract relative to the cylinder body 2211 through the movable end. The cylinder body 2211 abuts against the side wall of the mounting groove 235 away from the movable end and provides a damping force for the first locking mechanism 21 to limit the closing speed of the door body 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 body 2211 to move relative to the mounting groove 235 through the movable end and releases the damping force on the first locking mechanism 21.

[0142] By setting the damping member 221, a damping force is provided during the door closing operation to reduce the door closing speed, thereby reducing the door closing impact sound; and there is no damping force when the door is opened, thereby reducing the door opening force and improving the user's comfort during use.

[0143] In some embodiments of the present application, Figures 2 to 4 ,as well as Figures 9 to 14 As shown, the first locking mechanism 21 also includes a first detection member 214 installed on the bracket 23. When the door body 100 is closed, the first hook 11 is inserted into the first slot 2113, the second hook 13 is locked with the second locking mechanism 24, and the first rotating member 211 triggers the first detection member 214.

[0144] Specifically, a first working surface 2115 is provided on the outer circumference 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 the first engaging groove 2113. The first working surface 2115 rotates to the position of the first detecting member 214, triggering the first detecting member 214. The first detecting member 214 then sends a detection signal to the cooking appliance 1000. The cooking appliance 1000 then determines that the door closing operation is complete based on the received signal. When the door is opened, the first rotating member 211 rotates in the opposite direction, separating the first working surface 2115 from the first detecting member 214, and releasing the triggering of the first detecting member 214. At this point, the cooking appliance 1000 does not receive the signal and therefore determines that the door 1000 is open.

[0145] By providing the first detection member 214 , the door closing state can be effectively detected, thereby improving the control accuracy.

[0146] It should be noted that the first detecting member 214 may be a contact switch or a position sensor, etc.

[0147] In some embodiments of the present application, Figure 2 、 Figure 4 、 Figure 9 、 Figure 11as well as Figure 13 As shown, 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 is engaged with the second slot of the second rotating member 241 .

[0148] When the door lock device 300 is used for the cooking appliance 1000, the user applies a closing force to the door body 100 during the process of closing the opening of the cavity 200. Under the action of the closing force, the door body 100 rotates relative to the cavity 200, and the holding member 10 moves toward the direction close to the cavity 200 as the door body 100 rotates. The first hook 11 first cooperates with the limiting member 212. During the movement of the first hook 11 relative to the bracket 23, an external force is applied to the limiting member 212, so that the limiting member 212 overcomes the second rebound force of the second elastic member 213 and moves in the direction away from the first rotating member 211, so as to release the restriction on the first rotating member 211. The first hook 11 abuts against the limiting protrusion 2114, and the first elastic member 2 The first rebound force provided by 15 drives the first rotating member 211, so that the first rotating member 211 rotates 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 extreme position relative to the bracket 23, the second hook 13 also reaches the extreme position. The first hook 11 is stuck in the first slot 2113, and the second hook 13 is stuck in the second slot, so that the door body 100 remains in the state of closing the opening of the cavity 200.

[0149] When the door body 100 closes the opening of the cavity 200, when the user needs to open the door body 100, by applying a door opening force (opposite to the direction of the door closing force) to the door body 100, the second hook 13 separates from the second slot, and the first hook 11 drives the first slot 2113, so that the first rotating member 211 overcomes the first rebound force of the first elastic member 215 and rotates in the opposite direction. When the first rotating member 211 is reset to the initial state, when the first hook 11 separates from the first slot 2113 and avoids the position of the limit member 212, the second rebound force of the second elastic member 213 drives the limit member 212 to move in the direction close to the first rotating member 211, so that the limit protrusion 2114 is again locked in the limit slot 2121 to limit the first rotating member 211, thereby realizing the door opening operation.

[0150] By providing the second rotating member 241 , effective cooperation with the second hook 13 is achieved, thereby improving the locking effect of the door body 100 .

[0151] It should be noted that a second mounting post 237 is provided on the bracket 23 (for example, it can be integrally formed with the bracket 23), 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 that protrudes from the second mounting hole, thereby achieving a rotatable connection between the second rotating member 241 and the bracket 23. This simple structure can effectively reduce manufacturing costs, and at the same time, it is easy to assemble and can effectively improve assembly efficiency.

[0152] The second rotating member 241 is provided with a second latching groove. The second latching groove is provided on the outer peripheral wall of the first rotating member 211 . The second latching groove is used to cooperate with the second hook 13 .

[0153] In some embodiments of the present application, Figure 2 、 Figure 4 、 Figure 9 、 Figure 11 as well as Figure 13 As shown, the second locking mechanism 24 further includes a second detecting member 243 mounted on the bracket 23 . When the door 100 is closed, the second hook 13 is engaged with the second slot, and the second rotating member 241 triggers the second detecting member 243 .

[0154] Specifically, a second working surface is provided on the outer circumference 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 the second slot. The second working surface rotates to the position of the second detection member 243, triggering the second detection member 243. The second detection member 243 then sends a detection signal to the cooking appliance 1000. The cooking appliance 1000 then determines that the door closing operation is complete based on the received signal. When the door is opened, the second rotating member 241 rotates in the opposite direction, separating the second working surface from the second detection member 243 and releasing the triggering of the second detection member 243. At this point, the cooking appliance 1000 does not receive the signal and therefore determines that the door 1000 is open.

[0155] By providing the second detecting member 243 , the door closing state can be effectively detected, thereby improving the control accuracy.

[0156] It should be noted that the second detecting member 243 may be a contact switch or a position sensor, etc.

[0157] In some embodiments of the present application, Figure 2 、 Figure 4 、 Figure 9 、 Figure 11 as well as Figure 13As shown, the second locking mechanism 24 also includes a third elastic member 242, which cooperates with the second rotating member 241 and the bracket 23 respectively. The third elastic member 242 has a critical position, and the third elastic member 242 has a third rebound force. When the second hook 13 is not inserted into the second slot, the third rebound force drives the second rotating member 241 to rotate in the first direction. When the second hook 13 is inserted into the second slot and passes the critical position, the third rebound force drives the second rotating member 241 to rotate in the second direction. The first direction is opposite to the second direction.

[0158] When the door lock device 300 is used for the cooking appliance 1000, the user applies a closing force to the door body 100 during the process of closing the opening of the cavity 200. Under the action of the closing force, the door body 100 rotates relative to the cavity 200, and the holding member 10 moves toward the direction close to the cavity 200 as the door body 100 rotates. The first hook 11 first cooperates with the limiting member 212. During the movement of the first hook 11 relative to the bracket 23, an external force is applied to the limiting member 212, so that the limiting member 212 overcomes the second rebound force of the second elastic member 213 and moves in the direction away from the first rotating member 211, so as to release the limit on the first rotating member 211. The first hook 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 the rotation of the first rotating member 211, the first engaging groove 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). 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 exceeds 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 engaging groove drives the second hook 13 to move synchronously. When the first hook 11 moves to the extreme position relative to the bracket 23, the second hook 13 also reaches the extreme position. The first hook 11 engages with the first engaging groove 2113, and the second hook 13 engages with the second engaging groove, thereby maintaining the door body 100 in a state of closing the opening of the cavity 200.

[0159] When the door body 100 closes the opening of the cavity 200, when the user needs to open the door body 100, by applying a door-opening force (opposite to the direction of the door-closing force) to the door body 100, the second hook 13 drives the second slot to overcome the third rebound force of the third elastic member 242 and rotate in the first 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 in the first direction and reset, the second hook 13 separates from the first hook 11, and the first hook 11 is aligned with the first slot 2113 is driven, so that the first rotating member 211 overcomes the first rebound force of the first elastic member 215 and rotates in the opposite direction. When the first rotating member 211 is reset to the initial state, when the first hook 11 is separated from the first slot 2113 and avoids the position of the limiting member 212, the second rebound force of the second elastic member 213 drives the limiting member 212 to move toward the direction close to the first rotating member 211, so that the limiting protrusion 2114 is again stuck in the limiting slot 2121 to limit the first rotating member 211, thereby realizing the door opening operation.

[0160] By providing the third elastic member 242 , the second hook 13 can be automatically locked and reset together with the second rotating member 241 , thereby improving the convenience of the user during use.

[0161] It should be noted that, in the present application, the third elastic member 242 is a torsion spring.

[0162] like Figures 1 to 14 As shown, the second aspect of the present application proposes a cooking appliance 1000, which includes a cavity 200, a door body 100 and a door locking device 300 as described above, wherein the cavity 200 includes an opening, the door body 100 is pivotally connected to the cavity 200 and is used to open or close the opening, the holding member 10 of the door locking device 300 is installed on the door body 100, and the bracket 23 of the locking assembly 20 of the door locking device 300 is installed on the cavity 200 and is located on one side of the opening.

[0163] According to the cooking appliance 1000 of the present application, an external force drives the door body 100 to close the opening of the cavity 200, and the door closing force acts on the door body 100, so that the first hook 11 first cooperates with the first locking mechanism 21. When the first locking mechanism 21 switches from the first state to the second state, the door closing force can be released, and the first locking mechanism 21 cooperates with the first hook 11 to drive the first hook 11 to move relative to the bracket 23 until the first hook 11 is locked with the first locking mechanism 21 and the second hook 13 cooperates with the second locking mechanism 24.

[0164] The first locking mechanism 21 is used to drive the first hook 11 to move relative to the bracket 23, so that the first hook 11 is locked with the first locking mechanism 21 and the second hook 13 cooperates with the second locking mechanism 24, reducing the closing force applied when the door body 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 situation where the door body 100 hits the cavity 200, thereby improving the user experience.

[0165] The above-mentioned cooking appliance can be an oven or a cooking appliance with a microwave cooking function. In the present application, the above-mentioned cooking appliance is a cooking appliance with a microwave cooking function. For the structure of other parts of the cooking appliance with a microwave cooking function, please refer to the prior art and will not be elaborated in this application.

[0166] The above description is merely a preferred embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
