[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.

[0010] In addition, the door lock device according to the present application may also have the following additional technical features:

[0031] A second aspect of the present application provides a cooking appliance, comprising:

[0071] like Figures 1 to 12As 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.

[0072] 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.

[0073] In some embodiments of the present application, Figure 2 、 Figure 3 , and 8 to Figure 12 As shown, the holding member 10 includes a mounting portion 12, a first hook 11 and a second hook 13, wherein the mounting portion 12, the first hook 11 and the second hook 13 are an integrated structure, the first hook 11 and the second hook 13 are arranged in parallel and spaced apart, and the opening directions of the two are arranged facing each other. At the same time, the length of the first hook 11 is larger than that of the second hook 13.

[0074] The mounting portion 12, the first hook 11 and the second hook 13 are of an integrated structure and 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 holding part 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.

[0075] 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 direction of the first opening is opposite to the direction of the second opening.

[0076] 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.

[0077] 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 is first matched with the locking component 20. When the first hook 11 moves a distance relative to the locking component 20, the second hook 13 is matched 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 state of keeping the door body 100 in the opening of the closed cavity 200.

[0078] In some embodiments of the present application, along a first direction, a size of the first hook 11 is greater than a size of the second hook 13 , wherein the first direction is a length direction of the cavity 200 .

[0079] 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 236 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 236, further reducing the failure rate of the door lock device 300.

[0080] 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.

[0081] In some embodiments of the present application, 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 .

[0082] 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 236 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 236, further reducing the failure rate of the door lock device 300.

[0083] 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 direction of the cavity 200.

[0084] In some embodiments of the present application, Figure 2 、 Figure 3 , and 8 to Figure 12As 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.

[0085] 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 with the locking accessory, 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.

[0086] 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.

[0087] 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 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 is locked (i.e. locked) by the first locking mechanism 21. In the process of the first locking mechanism 21 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.

[0088] 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.

[0089] 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.

[0090] When the door lock device 300 of the present application is used in a 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 first 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 is released, and the first locking mechanism 21 engages with the hook to drive the hook to move relative to the bracket 23 until the first hook 11 is locked and engaged with the first locking mechanism 21 and the second hook 13 is engaged 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, achieving the locking and engagement of the first hook 11 with the first locking mechanism 21 and the engagement of the second hook 13 with the second locking mechanism 24. This reduces 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 impact of the door body 100 on the cavity 200, thereby improving the user experience.

[0091] It should be pointed out that if Figure 2 、 Figures 4 to 6 As shown, 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 first socket 235 and a second socket 236 arranged at intervals, the first socket 235 is arranged opposite to the first hook 11, and the second socket 236 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.

[0092] When the holder 10 is locked with the assembly 20 , the first hook 11 is inserted into the bracket 23 from the first insertion hole 235 and locked with the first locking mechanism 21 , and the second hook 13 is inserted into the bracket 23 from the second insertion hole 236 and locked with the second locking mechanism 24 .

[0093] 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.

[0094] In some embodiments of the present application, Figure 2 、 Figure 3 , and 7 to Figure 12 As shown, the first locking mechanism 21 includes a first rotating member 211 , a limiting member 212 and a first elastic member 215 .

[0095] 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.

[0096] A first mounting post 231 is provided on the bracket 23 (e.g., it can be integrally formed with the bracket 23). A first mounting hole 2115 is formed on the first rotating member 211. The first mounting post 231 is inserted into the first mounting hole 2115. A first limiting member is provided at one end of the first mounting post 231 that protrudes from the first mounting hole 2115. The first limiting member axially limits the first rotating member 211 on the first mounting post 231, thereby reducing the possibility of the first rotating member 211 falling off while 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.

[0097] The first rotating member 211 is provided with a first latching groove 2112 . The first latching groove 2112 is provided on the outer peripheral wall of the first rotating member 211 . The first latching groove 2112 is used to cooperate with the first hook 11 .

[0098] 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.

[0099] The first elastic member 215 cooperates with the first rotating member 211 and the bracket 23 respectively. The first elastic member 215 is in an elastic deformation state. The first elastic member 215 in the elastic deformation state has a first rebound force. The first elastic member 215 includes a first inflection point position. On one side of the first inflection point position, the first rebound force drives the first rotating member 211 to have a tendency to rotate in the first direction A. On the other side of the first inflection point position, the first rebound force drives the first rotating member 211 to have a tendency to rotate in the second direction B. The first direction A is opposite to the second direction B.

[0100] Among them, driven by the closing force, the first hook 11 drives the limiting member 212 to release the limit on the first rotating member 211, and drives the first rotating member 211 that has been released from the limit to rotate relative to the bracket 23 after at least overcoming the first rebound force. The first rotating member 211 drives the first elastic member 215 to cross the first inflection point position. When the closing force is released, the first slot 2112 drives the first hook 11 to move relative to the bracket 23, so that the first hook 11 is locked in the first slot 2112, and the second hook 13 is locked with the second locking mechanism 24.

[0101] It should be understood that, in the present application, the first elastic member 215 cooperates with the bracket 23 and the first rotating member 211 respectively, and the first elastic member 215 can rotate relative to the bracket 23 and the first rotating member 211 respectively. When the first rotating member 211 rotates relative to the bracket 23, the first rotating member 211 drives the first elastic member 215 to rotate synchronously, so that the first elastic member 215 accumulates force. When the first elastic member 215 accumulates force to the maximum position, the first rotating member 211 continues to rotate relative to the bracket 23, and the stored force of the first elastic member 215 is gradually released. At this time, the first The maximum force storage position of the elastic member 215 is the first inflection point position of the first elastic member 215. The first rebound force of the first elastic member 215 is the largest at the first inflection point position. When the first elastic member 215 is located on opposite sides of the first inflection point position, when the first rebound force provided by the first elastic member 215 drives the first rotating member 211, the rotation direction of the first rotating member 211 is opposite. For example, on one side of the first inflection point position, the first rebound force drives the first rotating member 211 to rotate clockwise, and on the other side of the first inflection point position, the first rebound force drives the first rotating member 211 to rotate counterclockwise.

[0102] 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 hook 11 abuts against the first rotating member 211 and continues to move relative to the bracket 23. During the movement, it is necessary to overcome the first rebound force (the direction of the driving force provided by the first rebound force to the first rotating member 211 is the same as the moving direction of the first hook 11). When the first hook 11 moves to the extreme position relative to the bracket 23, the first hook 11 is engaged with the first slot 2112, 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.

[0103] 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 2112, so that the first rotating member 211 overcomes the first rebound force of the first elastic member 215 and rotates in the opposite direction (the direction of the driving force provided by the first rebound force to the first rotating member 211 is opposite to the moving direction of the first hook 11). When the first elastic member 215 passes the inflection point, the first rebound force Continue to drive the first rotating member 211 to rotate (the direction of the driving force provided by the first rebound force to the first rotating member 211 is the same as the moving direction of the first hook 11), the first rotating member 211 drives the first hook 11 to move in the direction of separation from the locking component 20 through the first slot 2112. When the first rotating member 211 is reset to the initial state, when the first hook 11 is separated from the first slot 2112 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.

[0104] The first rotating member 211 is limited by the limiting member 212, and the first inflection point position of the first elastic member 215 is used for reversing. When the user closes the door, the first rebound force provided by the first elastic member 215 drives the first hook 11 through the first slot 2112 on the first rotating member 211. Without the user applying any external force, the first rotating member 211 can lock the holding member 10 with the locking component 20 by driving the first hook 11 to move, thereby effectively reducing the driving force when the user closes the door, thereby effectively improving the user experience.

[0105] In some embodiments of the present application, Figure 2 、 Figure 3 , and 8 to Figure 12 As shown, the first elastic member 215 is a first torsion spring, one connecting arm of the first torsion spring is rotatably connected to the bracket 23 and has a first rotation center 201, the other connecting arm of the first torsion spring is rotatably connected to the first rotating member 211 and has a second rotation center 202, the first rotating member 211 has a third rotation center 203, and when the first rotation center 201, the second rotation center 202 and the third rotation center 203 are collinear, the first elastic member 215 is at a first inflection point position.

[0106] Specifically, the first torsion spring is connected to the bracket 23 and the first rotating member 211 respectively. The first torsion spring and the bracket 23 are rotatably connected, and the first torsion spring and the first rotating member 211 are rotatably connected. When the first rotating member 211 rotates relative to the bracket 23, the first rotating member 211 drives the first torsion spring to twist and store force. When the first torsion spring is at the first inflection point, the stored force of the first torsion spring reaches the maximum. When the first rotating member 211 continues to rotate, the first torsion spring releases the stored force, that is, the first torsion spring reverses the driving force of the first rotating member 211 at the first inflection point.

[0107] The first elastic member 215 is configured as a first torsion 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 and thus reducing the failure rate of the door lock device 300 .

[0108] In addition, the first torsion spring has a simple structure and is easy to install, which can shorten the assembly time and effectively improve the assembly efficiency.

[0109] In addition, the first torsion spring has a wide range of materials, which can effectively reduce the cost of manufacturing and maintenance and replacement.

[0110] It should be pointed out that a first hanging hole 233 is provided in the bracket 23, and a first hanging structure is provided on the first rotating member 211, wherein the first hanging structure can also be a hanging hole structure, and one connecting arm of the first torsion spring is hung in the first hanging hole 233 and can rotate relative to the first hanging hole 233, and the other connecting arm of the first torsion spring is hung in the first hanging structure and can rotate relative to the first hanging structure.

[0111] In some embodiments of the present application, Figure 2 、 Figure 3 , and 8 to Figure 12 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.

[0112] 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 in 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 first rotating member 211 and continues to move relative to the bracket 23. During the movement, it is necessary to overcome the first rebound force (the direction of the driving force provided by the first rebound force to the first rotating member 211 is the same as that of the first hook 1 1) and damping force, when the first elastic member 215 passes the first inflection point position, the closing force is released, and the first rebound force provided by the first elastic member 215 drives the first rotating member 211 (the direction of the driving force provided by the first rebound force to the first rotating member 211 is the same as the moving direction of the first hook 11), so that the first rotating member 211 continues to rotate relative to the bracket 23. During the rotation of the first rotating member 211, the first slot 2112 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 stuck in the first slot 2112, 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.

[0113] 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 2112, so that the first rotating member 211 overcomes the first rebound force of the first elastic member 215 and rotates in the opposite direction (the direction of the driving force provided by the first rebound force to the first rotating member 211 is opposite to the moving direction of the first hook 11). When the first elastic member 215 passes the inflection point position, the first rebound force continues to drive the first rotating member 211 to rotate (the first rebound force The direction of the driving force provided by a rebound force to the first rotating member 211 is the same as the moving direction of the first hook 11), and the first rotating member 211 drives the first hook 11 to move in the direction of separation from the locking component 20 through the first slot 2112. When the first rotating member 211 is reset to the initial state, when the first hook 11 is separated from the first slot 2112 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 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.

[0114] 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.

[0115] 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.

[0116] In some embodiments of the present application, Figure 2 、 Figure 3 , and 8 to Figure 12 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 2113 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 2113 is locked in the limiting groove 2121. Through the cooperation between the limiting protrusion 2113 and the limiting groove 2121, the first rotating member 211 is limited.

[0117] 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 in the direction closer 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 first rotating member 211 and continues to move relative to the bracket 23. During the movement, it is necessary to overcome the first rebound force (the direction of the driving force provided by the first rebound force to the first rotating member 211 is opposite to the moving direction of the first hook 11) When the first hook 11 moves to the extreme position relative to the bracket 23, the first hook 11 is engaged with the first slot 2112, and at the same time, the second hook 13 is locked and cooperated with the second locking mechanism 24, so that the door body 100 remains in the state of closing the opening of the cavity 200.

[0118] 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 2112, so that the first rotating member 211 overcomes the first rebound force of the first elastic member 215 and rotates in the opposite direction (the direction of the driving force provided by the first rebound force to the first rotating member 211 is opposite to the moving direction of the first hook 11). When the first elastic member 215 passes the inflection point position, the first rebound force continues to drive the first rotating member 211 to rotate (the first rebound force The direction of the driving force provided by the first rotating member 211 is the same as the moving direction of the first hook 11), and the first rotating member 211 drives the first hook 11 to move in the direction of separation from the locking component 20 through the first slot 2112. When the first rotating member 211 is reset to the initial state, when the first hook 11 is separated from the first slot 2112 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 in the direction close to the first rotating member 211, so that the limiting protrusion 2113 is again locked in the limiting slot 2121 to limit the first rotating member 211, thereby realizing the door opening operation.

[0119] The limiting structure formed by the limiting groove 2121 and the limiting protrusion 2113 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 2113 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.

[0120] It should be pointed out that the limiting protrusion 2113 is integrally formed on the first rotating member 211 and is arranged adjacent to the first clamping groove 2112. In the present application, the limiting protrusion 2113 is a structure formed by the side wall protruding from the side of the first clamping groove 2112 away from the clamping member 10.

[0121] In some embodiments of the present application, Figure 3 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.

[0122] 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.

[0123] 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.

[0124] In some embodiments of the present application, Figure 3 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.

[0125] 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 .

[0126] It should be noted that the transmission member 222 can be a connecting rod mechanism or a gear mechanism, etc.

[0127] In some embodiments of the present application, Figure 3 and Figure 7 As shown, the transmission member 222 is a rack, and continuous teeth 2111 are provided on the outer peripheral side of the transmission member 222. The continuous teeth 2111 are arranged along the rotation direction of the first rotating member 211 and mesh 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.

[0128] Specifically, continuous teeth 2111 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 2111 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.

[0129] 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.

[0130] In some embodiments of the present application, a mounting slot is provided on the bracket 23, and a damping member 221 is disposed within the mounting slot. 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.

[0131] In this application, if Figure 3 As shown, the locking assembly 20 also includes a cover plate 25, which cooperates with the bracket to close the notch of the installation slot, 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.

[0132] 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 2111 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 side wall of the mounting groove facing away from the movable end abuts against the cylinder body 2211 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 through the movable end and releases the damping force on the first locking mechanism 21.

[0133] 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.

[0134] In some embodiments of the present application, Figure 2 、 Figure 3 , and 8 to Figure 12 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 2112, the second hook 13 is locked with the second locking mechanism 24, and the first rotating member 211 triggers the first detection member 214.

[0135] Specifically, a first working surface 2114 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 2112. The first working surface 2114 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 2114 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.

[0136] By providing the first detection member 214 , the door closing state can be effectively detected, thereby improving the control accuracy.

[0137] It should be noted that the first detecting member 214 may be a contact switch or a position sensor, etc.

[0138] In some embodiments of the present application, Figure 2 、 Figure 3 、 Figure 6 , and 8 to Figure 12 As shown, the second locking mechanism 24 includes a second rotating member 241 rotatably arranged on the bracket 23, and a second slot 2413 is provided on the second rotating member 241. When the door body 100 is closed, the second hook 13 is engaged with the second slot 2413 of the second rotating member 241.

[0139] 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, and the first hook 11 abuts against the limiting protrusion 2113. The first elastic member 215 The first rebound force provided 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 2112 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 2112, and the second hook 13 is stuck in the second slot 2413, so that the door body 100 remains in the state of closing the opening of the cavity 200.

[0140] 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 2413, and the first hook 11 drives the first slot 2112, 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 2112 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 2113 is again locked in the limit slot 2121 to limit the first rotating member 211, thereby realizing the door opening operation.

[0141] 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 .

[0142] It should be pointed out that if Figure 6 As shown, a protrusion 2414 is provided on the second rotating member 241. When the second hook 13 and the second rotating member 241 are driven, the second hook 13 abuts against the protrusion 2414, thereby driving the second rotating member 241 to rotate relative to the bracket 23.

[0143] In addition, the protrusion 2414 is integrally formed on the second rotating member 241 and is arranged adjacent to the second clamping groove 2413. In the present application, the protrusion 2414 is a structure formed by protruding from the side wall of the second clamping groove 2413 away from the clamping member 10.

[0144] In addition, a second mounting post 232 is provided on the bracket 23 (for example, it can be integrally formed with the bracket 23), and a limiting protrusion 2321 is provided on the outer circumference of the second mounting post 232. The limiting protrusion 2321 is provided near the end of the second mounting post 232 away from the bracket 23. A second mounting hole 2411 is opened on the second rotating member 241, and an avoidance structure 2412 is provided on the hole wall of the second mounting hole 2411. When the second rotating member 241 is installed, the second mounting hole 2411 and the second mounting post 232 are aligned. The second mounting post 232 is inserted into the second mounting hole 2411. After the second mounting post 232 is installed, the limiting protrusion 2321 protrudes relative to the second rotating member 241. By rotating the second rotating member 241, the limiting protrusion 2321 and the avoiding structure 2412 are staggered. The limiting protrusion 2321 and the second rotating member 241 are axially limited, thereby achieving a rotatable connection between the second rotating member 241 and the bracket 23. This simple structure can effectively reduce manufacturing costs, facilitate assembly, and effectively improve assembly efficiency.

[0145] The second rotating member 241 is provided with a second latching groove 2413 . The second latching groove 2413 is provided on the outer peripheral wall of the first rotating member 211 . The second latching groove 2413 is used to cooperate with the second hook 13 .

[0146] In some embodiments of the present application, Figure 2 、 Figure 3 , and 8 to Figure 12 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 2413 , and the second rotating member 241 triggers the second detecting member 243 .

[0147] Specifically, a second working surface 2416 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 engaging groove 2413. The second working surface 2416 rotates to the position of the second detecting member 243, triggering the second detecting member 243. The second detecting 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 2416 from the second detecting member 243, and releasing the triggering of the second detecting member 243. At this point, the cooking appliance 1000 does not receive the signal and therefore determines that the door 1000 is open.

[0148] By providing the second detecting member 243 , the door closing state can be effectively detected, thereby improving the control accuracy.

[0149] It should be noted that the second detecting member 243 may be a contact switch or a position sensor, etc.

[0150] In some embodiments of the present application, Figure 2 、 Figure 3 , and 8 to Figure 12 As shown, the second locking mechanism 24 also includes a third elastic member 242, which cooperates with the bracket 23 and the second rotating member 241 respectively. The third elastic member 242 includes a second inflection point position and has a third rebound force. On one side of the second inflection point position, the third rebound force drives the first rotating member to have a tendency to rotate in the second direction B, and on the other side of the second inflection point position, the third rebound force drives the second rotating member to have a tendency to rotate in the first direction A. After the first elastic member 215 passes the first inflection point position, the second hook 13 cooperates with the second rotating member 241 and drives the second rotating member 241 to rotate relative to the bracket 23 after at least overcoming the third rebound force. The second rotating member 241 drives the third elastic member 242 to pass the second inflection point position so that the second hook 13 is engaged in the second slot 2413.

[0151] Among them, under the driving force of closing the door, the first hook 11 drives the limiting member 212 to release the limit on the first rotating member 211, and drives the first rotating member 211 that has been released from the limit to rotate relative to the bracket 23 after at least overcoming the first rebound force. The first rotating member 211 drives the first elastic member 215 to cross the first inflection point position. When the closing force is released, the first slot 2112 drives the first hook 11 to move relative to the bracket 23, so that the first hook 11 is locked in the first slot 2112. At the same time, the second hook 13 The second rotating member 241 is driven to rotate relative to the bracket 23. During the rotation of the second rotating member 241 relative to the bracket 23, the third elastic member 242 is driven to accumulate force. When the third elastic member 242 passes the second inflection point, the third elastic member 242 drives the second hook 13 through the second slot 2413 so that the second hook 13 continues to move relative to the bracket 23 until the second hook 13 is engaged in the second slot 2413, thereby realizing the locking of the holding member 10 and the locking component 20.

[0152] It should be understood that, in the present application, the third elastic member 242 cooperates with the bracket 23 and the second rotating member 241 respectively, and the third elastic member 242 can rotate relative to the bracket 23 and the second rotating member 241 respectively. When the second rotating member 241 rotates relative to the bracket 23, the second rotating member 241 drives the third elastic member 242 to rotate synchronously, so that the third elastic member 242 accumulates force. When the third elastic member 242 accumulates force to the maximum position, the second rotating member 241 continues to rotate relative to the bracket 23, and the stored force of the third elastic member 242 is gradually released. At this time, the third The maximum force storage position of the elastic member 242 is the second inflection point position of the third elastic member 242. The third rebound force of the third elastic member 242 is the largest at the second inflection point position. When the third elastic member 242 is located on opposite sides of the second inflection point position, when the third rebound force provided by the third elastic member 242 drives the second rotating member 241, the rotation direction of the second rotating member 241 is opposite. For example, on one side of the second inflection point position, the third rebound force drives the second rotating member 241 to rotate clockwise, and on the other side of the second inflection point position, the third rebound force drives the second rotating member 241 to rotate counterclockwise.

[0153] In some embodiments of the present application, Figure 2 、 Figure 3 , and 8 to Figure 12 As shown, the third elastic member 242 is a second torsion spring, one connecting arm of the second torsion spring is rotatably connected to the bracket 23 and has a fourth rotation center 204, the other connecting arm of the second torsion spring is rotatably connected to the second rotating member 241 and has a fifth rotation center 205, the second rotating member 241 has a sixth rotation center 206, and when the fourth rotation center 204, the fifth rotation center 205 and the sixth rotation center 206 are collinear, the third elastic member 242 is at the second inflection point position.

[0154] Specifically, the second torsion spring is connected to the bracket 23 and the second rotating member 241 respectively. The second torsion spring and the bracket 23 are rotatably connected, and the second torsion spring and the second rotating member 241 are rotatably connected. When the second rotating member 241 rotates relative to the bracket 23, the second rotating member 241 drives the second torsion spring to twist and store force. When the second torsion spring is at the second inflection point, the stored force of the second torsion spring reaches the maximum. When the second rotating member 241 continues to rotate, the second torsion spring releases the stored force, that is, the second torsion spring reverses the driving force of the second rotating member 241 at the second inflection point.

[0155] The third elastic member 242 is configured as a second torsion spring, which can provide a continuous and stable third rebound force for the second rotating member 241 , thereby reducing plastic deformation due to long-term use, thereby reducing the failure rate of the door lock device 300 .

[0156] In addition, the second torsion spring has a simple structure and is easy to install, which can shorten the assembly time and effectively improve the assembly efficiency.

[0157] In addition, the second torsion spring has a wide range of materials, which can effectively reduce the cost of manufacturing and maintenance and replacement.

[0158] It should be pointed out that a second hanging hole 234 is provided in the bracket 23, and a second hanging structure 2415 is provided on the second rotating member 241, wherein the second hanging structure 2415 can also be a hanging hole structure, and one connecting arm of the second torsion spring is hung in the second hanging hole 234 and can rotate relative to the second hanging hole 234, and the other connecting arm of the second torsion spring is hung in the second hanging structure 2415 and can rotate relative to the second hanging structure 2415.

[0159] like Figures 1 to 12 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.

[0160] 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. 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 hook to drive the hook to move relative to the bracket 23 until the first hook 11 is locked and cooperated with the first locking mechanism 21 and the second hook 13 is cooperated with the second locking mechanism 24.

[0161] The first locking mechanism 21 is used to drive the first hook 11 to move relative to the bracket 23, thereby realizing the locking cooperation between the first hook 11 and the first locking mechanism 21 and the cooperation between the second hook 13 and the second locking mechanism 24, thereby 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.

[0162] 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.

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.
