[0003] In view of the above problems, this application provides a door lock device and a cooking appliance that can improve the reliability of the door lock device by preventing foreign objects from entering the door lock device.

[0004] In a first aspect, this application provides a door lock device for locking the door of a cooking appliance to its housing, comprising:

[0005] A locking component for connection with the housing, the locking component having a snap-in end having a first through hole;

[0006] A latching member is used to install on the door body. The latching member includes an installation part and a first latching part. The first latching part is detachably connected to the installation part. The first latching part is a metal part. The first latching part has a first locked state in which it passes through a first through hole from the latching end and latches with a locking component, and a first unlocked state in which it is separated from the locking component and can be moved out of the first through hole.

[0007] Provided that the first holding part has a predetermined strength and rigidity, the first holding part can be made of metal to reduce its volume, thereby reducing the area of ​​the first through hole.

The first connecting end of the second elastic member is rotatably connected to the bracket, and the second connecting end of the second elastic member is rotatably connected to the second movable member. When the second holding part is in the second unlocked state, the elastic force of the second elastic member tends to slow down the second holding part from entering the second slot.

[0019] In some embodiments of this application, the door lock device further includes a second micro switch, which is disposed on the bracket. When the second holding part is in the second locked state, the second moving member triggers the second micro switch.

[0020] In some embodiments of this application, the second holding part is a metal part.

For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0061] According to an embodiment of this application, a door lock device 100 is provided, please refer to... Figures 1-5The door 300 of a cooking appliance is used for locking to the housing 200. The door lock device 100 includes a locking component 20 and a retaining member 10. The locking component 20 is used to connect to the housing 200 and has a snap-in end 2111 with a first through hole 2121. The retaining member 10 is used to install on the door 300 and includes a mounting part 13 and a first retaining part 11. The first retaining part 11 is detachably connected to the mounting part 13 and is made of metal. The first retaining part 11 has a first locked state where it passes through the first through hole 2121 from the snap-in end 2111 and engages with the locking component 20, and a first unlocked state where it is separated from the locking component 20 and can be moved out of the first through hole 2121.

[0062] The door body 300 and the housing 200 can be engaged by a door lock device 100. Specifically, one end of the door body 300 is rotatably connected to the housing 200, and the other end of the door body 300 is locked to the housing 200 by the door lock device 100. Multiple door lock devices 100 can also be provided, and the door body 300 can be detachably locked to the housing 200 by the door lock device 100.

[0063] The material of the first holding part 11 can be, but is not limited to, steel, copper alloy or aluminum alloy.

[0064] The first holding part 11 can have holes that are, but are not limited to, rectangular holes, elliptical holes, or round holes.

[0065] In the cooking appliance 1000, the first retaining part 11 is typically manufactured using injection molding with a plastic component. This method facilitates the molding of the first retaining part 11. However, under the same strength, a metal first retaining part 11 would be smaller, allowing for a smaller area of ​​the first through hole 2121. This reduces the probability of foreign objects entering through the first through hole 2121 and causing the first retaining part 11 to fail to engage, thereby improving the reliability of the door lock device 100. Furthermore, it facilitates the replacement of the first retaining part 11 when it is damaged.

[0066] In some embodiments of this application, please refer to Figure 1 The retaining member 10 also includes a mounting part 13, and the first retaining part 11 is detachably connected to the mounting part 13.

[0067] As an example, the first retaining part 11 can be detachably connected to the mounting part 13 via a screw. Specifically, the first retaining part 11 has a connecting hole, and the mounting part 13 has a threaded hole. The shank of the screw passes through the connecting hole and is threaded into the threaded hole. Alternatively, the threaded hole can be replaced with a smooth hole, in which the shank of the screw passes through both the connecting hole and the smooth hole, and a nut is threaded onto the end of the shank.

[0068] Therefore, on the one hand, it facilitates the installation of the mounting part 13 and the first holding part 11, especially when the mounting part 13 and the first holding part 11 are made of two different materials, which makes installation easier and simplifies the manufacturing difficulty of the holding part 10. When the mounting part 13 and the first holding part 11 are integrally formed, it is necessary to design complex molds and manufacture them by injection molding or cutting, which increases the manufacturing cost and manufacturing difficulty. However, by adopting this separate design structure, the manufacturing difficulty can be simplified and the manufacturing cost can be reduced. At the same time, it is convenient to replace the first holding part 11 after it is damaged.

[0069] In some embodiments of this application, please refer to Figure 2 The first holding part 11 is a plate-shaped structure.

[0070] As an example, the first through hole 2121 can be a flat hole structure, such as a rectangular hole, an oblong hole, or an elliptical hole.

[0071] Therefore, the area of ​​the first through hole 2121 can be made smaller to reduce the probability of foreign objects entering, thereby improving the reliability of the engagement between the first holding part 11 and the locking component 20.

[0072] In some embodiments of this application, the bracket 21 includes a body portion 211 and a connecting portion 212. The body portion 211 has a snap-in end 2111 with an installation opening. A portion of the connecting portion 212 is located within the installation opening, and the connecting portion 212 is detachably connected to the body portion 211. The connecting portion 212 has a first through hole 2121.

[0073] The connection between the connecting part 212 and the main body part 211 includes, but is not limited to, snap-fit ​​or screw connection.

[0074] As an example, the connecting part 212 is connected to the body part 211 by a snap-fit. The main body of the connecting part 212 is a plate-shaped structure, and a part of the main body is located inside the mounting opening. The main body of the connecting part 212 is provided with a snap-fit, which is located inside the locking component 20 and engages with the body part 211.

[0075] As an example, the first holding part 11 can be a hook-shaped structure or a rod-shaped structure with locking protrusions at both ends.

[0076] Therefore, when the edge of the first through hole 2121 is damaged, the connecting part 212 can be replaced in time to avoid replacing the entire bracket 21. This not only saves material costs but also reduces maintenance time, thereby lowering maintenance costs. Without considering the replacement of the connecting part 212, the connection between the connecting part 212 and the main body 211 can be adhesive bonding or integral molding, etc.

[0077] In some embodiments of this application, please refer to Figures 3A-3DThe locking component 20 includes a bracket 21 and a first locking mechanism 22. The first locking mechanism 22 includes a first movable member 221, which is rotatably connected to the bracket 21. The first movable member 221 has a first slot 2211, and the first holding part 11 has a first locked state and a first unlocked state.

[0078] The first movable member 221 can be rotated with the bracket 21 by a motor drive to change the position of the first slot 2211, thereby achieving engagement or disengagement with the first holding part 11. The first movable member 221 can also be driven by an elastic component to achieve passive engagement with the first holding part 11.

[0079] As an example, the first holding part 11 is a hook structure, which includes a hook head 111 and a hook handle 112. The hook head 111 is connected to the hook handle 112, and the hook head 111 and the hook handle 112 together define an avoidance groove 113. After the first holding part 11 is engaged, part of the hook head 111 is located in the first slot 2211, and part of the first movable part 221 is located in the avoidance groove 113.

[0080] As an example, in order to improve the reliability of the engagement between the first slot 2211 and the first holding part 11, the bracket 21 is provided with a first limiting part 2112 and a second limiting part 2113. The first limiting part 2112 and the second limiting part 2113 are located at different positions on the bracket 21. Before the first holding part 11 engages, the first movable member 221 abuts against the first limiting part 2112. During the engagement process of the first holding part 11, the second limiting part 2113 is used to limit the rotation angle of the first movable member 221.

[0081] Thus, the first latching part 11 and the first latching slot 2211 can be engaged and disengaged, thereby enabling the door lock device 100 to open when the door is opened and lock when the door is closed.

[0082] In some embodiments of this application, please refer to Figures 3A-3D The first locking mechanism 22 also includes a first elastic member 222. The first end 2221 of the first elastic member 222 is rotatably connected to the bracket 21, and the second end 2222 of the first elastic member 222 is rotatably connected to the first movable member 221. When the first holding part 11 is in the first unlocked state, the elastic force of the first elastic member 222 tends to slow down the first holding part 11 from entering the first slot 2211. When the first holding part 11 is in the locked state, the elastic force of the first elastic member 222 tends to prevent the first holding part 11 from separating from the first slot 2211.

[0083] The first elastic element 222 includes, but is not limited to, any one of a torsion spring or an elastic telescopic rod.

[0084] As an example, please refer to Figure 3DThe elastic telescopic rod can be an air spring; the elastic telescopic rod can also include a first rod, a second rod and a first compression spring. The first rod is a hollow rod, a part of the second rod is located in the cavity of the first rod and extends out from one end of the first rod, the other end of the first rod is blocked, and a first compression spring is provided between the other end of the first rod and the second rod.

[0085] For ease of representation, the axis of rotation of the first movable member 221 relative to the bracket 21 is the first axis.

[0086] As an example, please refer to Figures 3A-3C The first elastic element 222 can be a torsion spring, so that... Figure 3A With the indicated direction as a reference, the torsion spring is located below the first movable member 221. The bracket 21 is provided with a first connecting hole, and the first movable member 221 is provided with a second connecting hole. One end of the torsion spring is rotatably connected to the first connecting hole, and the other end of the torsion spring is rotatably connected to the second connecting hole. The insertion position of the torsion spring and the second connecting hole is offset from the first axis.

[0087] As an example, please refer to Figure 3E The first elastic element 222 can be a first tension spring. One end of the first tension spring is connected to the bracket 21, and the other end is connected to the first movable element 221. The position where the first tension spring is connected to the bracket 21 is above the first movable element 221 and located behind the first axis along the insertion direction X. The position where the first tension spring is connected to the first movable element 221 is below the first axis. When the first holding part 11 exits from the insertion end 2111, the position where the first tension spring is connected to the first movable element 221 is located behind the first axis along the insertion direction X. When the first holding part 11 is engaged, the position where the first tension spring is connected to the first movable element 221 is located in front of and below the first axis along the insertion direction X. During the engagement process, the first tension spring crosses the first axis so that the torque direction of the first tension spring acting on the first movable element 221 is opposite to that before the first holding part 11 is engaged, so that the engagement of the first holding part 11 can be slowed down during engagement and the engagement state can be maintained after engagement.

[0088] The first elastic element 222 slows down the engagement speed of the first latching part 11. On the one hand, it can buffer the noise of the door 300 impacting the housing 200 when closing, and on the other hand, it can reduce the engagement noise of the first latching part 11. At the same time, it allows the first latching part 11 to switch between the unlocked and locked states by overcoming the elastic force of the first elastic element 222 through external force, which facilitates the opening and closing operations.

[0089] In some embodiments of this application, please refer to Figures 3A-3DThe first end 2221 has a first rotation center between itself and the bracket 21, the second end 2222 has a second rotation center between itself and the first movable member 221, and the first movable member 221 has a third rotation center between itself and the bracket 21. On the first cross section of the first movable member 221, the straight line passing through the third rotation center and the second rotation center is the first straight line Z. When the first holding part 11 switches from the first unlocked state to the first locked state, the trajectory curve of the second rotation center intersects with the first straight line Z. The first cross section is perpendicular to the axis of rotation of the first movable member 221 relative to the bracket 21.

[0090] As an example, please refer to Figure 3D The first elastic element 222 can be a first elastic telescopic rod, one end of which is rotatably connected to the bracket 21, and the other end of which is rotatably connected to the first movable element 221. On the same plane perpendicular to the axis of rotation of the first elastic telescopic rod and the bracket 21, during the engagement process of the first holding part 11, the first movable element 221 is driven by the first holding part 11 and rotates relative to the bracket 21. Simultaneously, the first elastic telescopic rod swings relative to the bracket 21, and the second rotation center intersects the first straight line Z. Before the first holding part 11 engages, the first movable member 221 remains in an unlocked state under the elastic force of the first elastic telescopic rod. When the first holding part 11 moves toward the first slot 2211 and overcomes the elastic force of the first elastic telescopic rod, the first movable member 221 rotates. When the second rotation center moves to the first straight line Z, the elastic force of the first elastic telescopic rod will not cause the first movable member 221 to rotate. As the first holding part 11 further causes the first movable member 221 to rotate, the torque direction of the first elastic telescopic rod acting on the first movable member 221 changes. That is, during the engagement process, the torque direction changes from the counterclockwise direction in the figure to the clockwise direction.

[0091] During the card receiving process of the first card holder 11, with Figures 3A-3C As shown for reference, the first movable member 221 rotates clockwise to engage with the first slot 2211. The first elastic member 222 slows down the speed at which the first holding part 11 engages with the first slot 2211. On the one hand, it can buffer the noise of the door 300 impacting the housing 200 when closing, and on the other hand, it can reduce the engagement noise between the first holding part 11 and the first slot 2211.

[0092] In some embodiments of this application, please refer to Figure 1 The door lock device 100 also includes a first micro switch 28, which is disposed on the bracket 21. When the first holding part 11 is in the first locked state, the first moving part 221 triggers the first micro switch 28.

[0093] As an example, with Figure 1As shown in the reference direction, the first micro switch 28 is located below the first movable member 221.

[0094] The first micro switch 28 can be connected to the bracket 21 by screws, or it can be fixed to the bracket 21 by snap-fit ​​or adhesive.

[0095] Taking a cooking appliance 1000 as an example, such as a common microwave oven, during microwave oven use, when the door is closed, the first latch reaches a locked state. At this time, the first latch precisely triggers the first microswitch 28, thereby generating a door-closing signal. For example, when a user prepares to heat food and closes the microwave oven door, if the first latch is not in the correct locked state, the first microswitch 28 will not be triggered, and the microwave oven will not start. Only when the first latch successfully locks and triggers the first microswitch 28, generating a door-closing signal, will the microwave oven's heating function be activated. This effectively prevents the microwave oven from being started when the door is not properly closed, avoiding potential harm to the human body caused by microwave leakage.

[0096] In some embodiments of this application, please refer to Figures 1-3D The retaining member 10 also includes a second retaining part 12, which is spaced apart from the first retaining part 11 along the first direction Y. The second retaining part 12 is connected to the mounting part 13. The inserting end 2111 is provided with a second through hole 2114, which is spaced apart from the first through hole 2121 along the first direction Y. The locking assembly 20 also includes a second locking mechanism 23, which is spaced apart from the first locking mechanism 22 along the first direction Y. The second locking mechanism 23 includes a second movable member 23. 1. The second movable member 231 is rotatably connected to the bracket 21. The second movable member 231 has a second slot 2311. The second holding part 12 has a second locked state that passes through the second through hole 2114 from the insertion end 2111 and engages with the second slot 2311, and a second unlocked state that separates from the second slot 2311 and can be moved out from the second through hole 2114. The first direction Y is perpendicular to the insertion direction X of the holding member 10. The rotation axis of the second movable member 231 relative to the bracket 21 is perpendicular to the first direction Y.

[0097] Taking the microwave oven as an example of the cooking appliance 1000, when one end of the door 300 is pivotally connected to the housing 200 and the other end of the door 300 is locked by the door lock device 100, the locking direction X is the direction in which the door 300 rotates relative to the housing 200. The first direction Y is perpendicular to the locking direction X of the holding member 10, meaning that the first direction Y is perpendicular to both the normal and tangential directions of the rotation of the door 300 relative to the housing 200.

[0098] The second holding part 12 is connected to the mounting part 13, specifically by means of integral molding, riveting, welding or screw connection.

[0099] The second movable member 231 can be rotated with the bracket 21 by a motor drive to change the position of the second slot 2311, thereby enabling the active engagement and separation of the second slot 2311 and the second holding part 12. Alternatively, the second movable member 231 can be elastically connected to the bracket 21 by the second elastic member 232, and driven by the second holding part 12 to achieve passive engagement and separation of the second slot 2311 and the second holding part 12.

[0100] Taking the microwave oven as an example of the cooking appliance 1000, the setting of the second latching part 12 can increase the number of latching positions between the door 300 and the housing 200, thereby improving the reliability and stability of the door 300 when closing, thus reducing the probability of microwave leakage of the microwave oven when closing the door; at the same time, it reduces the deformation of the door 300 when closing the door, thereby reducing the impact sound of the door 300 against the housing 200 caused by deformation, and improving the user experience.

[0101] In some embodiments of this application, please refer to Figures 3A-3D The second locking mechanism 23 also includes a second elastic member 232. The first connecting end 2321 of the second elastic member 232 is rotatably connected to the bracket 21, and the second connecting end 2322 of the second elastic member 232 is rotatably connected to the second movable member 231. When the second holding part 12 is in the second unlocked state, the elastic force of the second elastic member 232 tends to slow down the second holding part 12 from entering the second slot 2311. When the second holding part 12 is in the locked state, the elastic force of the second elastic member 232 tends to prevent the second holding part 12 from separating from the second slot 2311.

[0102] The second elastic element 232 can be, but is not limited to, any one of a torsion spring or an elastic telescopic rod.

[0103] The second elastic element 232 can be, but is not limited to, any one of a torsion spring or an elastic telescopic rod, and the structure of the elastic telescopic rod can be, but is not limited to, the structures listed above.

[0104] For ease of explanation, please refer to Figure 3E The axis of rotation of the second movable part 231 relative to the bracket 21 is the second axis.

[0105] As an example, the second elastic element 232 can be a second tension spring. One end of the second tension spring is connected to the bracket 21, and the other end is connected to the second movable element 231. The position where the second tension spring is connected to the bracket 21 is above the first movable element 231 and located in front of the second axis along the snap-in direction X. The position where the second tension spring is connected to the second movable element 231 is below the second axis. When the second holding part 12 exits from the snap-in end 2111, the position where the second tension spring is connected to the second movable element 231 is in front of the second axis along the snap-in direction X. When the second holding part 21 is engaged, the position where the second tension spring is connected to the second movable element 231 is located behind and below the second axis along the snap-in direction X. During the engagement process, the second tension spring crosses the second axis so that the torque direction of the second tension spring acting on the second movable element 231 is opposite to that before the second holding part 21 is engaged, so that the engagement of the first holding part 12 can be slowed down during engagement and the engagement state can be maintained after engagement.

[0106] In some embodiments of this application, the first connecting end 2321 has a first rotation center with the bracket 21, the second connecting end 2322 has a second rotation center with the second movable member 231, and the second movable member 231 has a third rotation center with the bracket 21. On the second cross section of the second movable member 231, the straight line passing through the third rotation center and the first rotation center is the second straight line P. When the second holding part 12 switches from the second unlocked state to the second locked state, the trajectory curve of the second rotation center intersects with the second straight line P. The second cross section is perpendicular to the axis of rotation of the second movable member 231 relative to the bracket 21.

[0107] As an example, please refer to Figure 3D The second elastic element 232 is a second elastic telescopic rod. The first connecting end 2321 of the second elastic telescopic rod is rotatably connected to the bracket 21, and the other end of the second elastic telescopic rod is rotatably connected to the second movable element 231. In the second cross-section, during the engagement of the second holding part 12, the second movable element 231 is driven by the second holding part 12 and rotates relative to the bracket 21. At the same time, the second elastic telescopic rod rotates relative to the bracket 21, and the trajectory curve of the second rotation center intersects with the second straight line P. Before the second holding part 12 engages, the second movable element 231 remains in an unlocked state under the elastic force of the second elastic telescopic rod. When the second holding part 12 moves towards the second slot 2311 and overcomes the elastic force of the second elastic telescopic rod, it causes the second movable element 231 to rotate. When the second rotation center moves to the second straight line P, the elastic force of the second elastic telescopic rod will not cause the second movable element 231 to rotate. The direction of the torque acting on the second movable element 231 by the second elastic telescopic rod changes, that is, during the engagement process, the direction of the torque changes from the clockwise direction in the figure to the counterclockwise direction.

[0108] As an example, please refer to Figure 3A The second elastic element 232 is a torsion spring.

[0109] The trajectory curve of the second rotation center is an arc and intersects with the second straight line P. When the second holding part 12 is in the second unlocked state or the second locked state, the second elastic member 232 can provide elastic force in different directions to the second movable member 231. Specifically, when the second holding part 12 is in the second unlocked state and is located outside the second through hole 2114, the elastic force of the second elastic member 232 provides a component force in the opposite direction of the insertion direction X to the second movable member 231, so as to slow down the second holding part 12 entering the second slot 2311. When the second holding part 12 is in the second locked state, the elastic force of the second elastic member 232 provides a component force in the same direction of the insertion direction X to the second movable member 231, so as to prevent the second holding part 12 from separating from the second slot 2311.

[0110] In some embodiments of this application, the second holding part 12 can be a metal part, specifically, but not limited to, steel, copper alloy, or aluminum alloy. The second holding part 12 and the mounting part 13 can be connected by screws. To facilitate the manufacturing of the holding part 10, the second holding part 12 and the mounting part 13 are usually formed into an integral structure by injection molding, that is, the entire holding part 10 is made of plastic for easy injection molding. However, compared with the second holding part 12 being a metal part, the volume of the second holding part 12 is larger under the same strength, and the area of ​​the second through hole 2114 that needs to be made is also larger, making it easier for foreign objects to enter the locking assembly 20 through the second through hole 2114. Therefore, using a metal part for the second holding part 12 can make the area of ​​the second through hole 2114 smaller while meeting the strength requirements, thereby reducing the probability that foreign objects will enter the locking assembly 20 and cause the second holding part 12 and the second slot 2311 to fail to engage, thereby improving the reliability of engagement.

[0111] In some embodiments of this application, please refer to Figure 1 The door lock device 100 also includes a second micro switch 29, which is disposed on the bracket 21. When the second holding part 12 is in the second locked state, the second moving part 231 triggers the second micro switch 29.

[0112] The connection between the second micro switch 29 and the bracket 21 includes, but is not limited to, snap-fit, screw connection, or adhesive connection.

[0113] The second micro switch 29 can provide a door-closing signal for the second latching part 12 to engage with the second latching slot 2311, ensuring that the cooking appliance 1000 performs cooking operations after the door is closed. Taking a microwave oven as an example, this design can prevent the microwave oven from being started when the door is not closed tightly, avoiding potential harm to the human body caused by microwave leakage.

[0114] In some embodiments of this application, please refer to Figures 3A-3C The locking component 20 also includes a third elastic member 24, which is disposed on the bracket 21. When the second holding part 12 is in the unlocked state, the third elastic member 24 abuts against the second moving part 231 and the third elastic member 24 is in the compressed state.

[0115] The third elastic element 24 includes, but is not limited to, one of a compression spring, an elastic rubber element, an elastic telescopic rod, or an elastic polyurethane element. The elastic telescopic rod can be, but is not limited to, the examples mentioned above.

[0116] As an example, during the engagement of the second holding member 10 and the second slot 2311, the second movable member 231 can separate from the third elastic member 24 when it rotates at a certain angle, or it can remain in contact with the third elastic member 24.

[0117] In the second unlocked state, the second movable member 231 remains balanced under the force of the third elastic member 24 and the second elastic member 232. On the one hand, when the second holding part 12 is unlocked, the third elastic member 24 can buffer the impact of the second movable member 231 on the bracket 21 to reduce damage to the bracket 21 and extend the service life of the bracket 21. On the other hand, during the process of the second holding part 12 being inserted into the second slot 2311, the elastic force of the third elastic member 24 can offset part of the elastic force of the second elastic member 232 to reduce the thrust acting on the holding member 10, making it easier to engage.

[0118] In some embodiments of this application, please refer to Figure 2 The locking assembly 20 also includes a damping component 30, which is disposed on the bracket 21. The damping component 30 is used to provide damping force to the second movable member 231 to slow down the speed at which the second holding part 12 engages with the second slot 2311.

[0119] The damping component 30 includes either an elastic telescopic rod or a damper 32.

[0120] The damping component 30 can further slow down the speed at which the second retaining part 12 enters the second slot 2311, so as to reduce the impact sound between the door 300 and the housing 200 when the door 300 of the cooking appliance 1000 is closed. At the same time, after the second retaining part 12 enters the second slot 2311, the sound of the second retaining part 12 engaging with the second slot 2311 can also be reduced.

[0121] In some embodiments of this application, please refer to Figure 2The second movable member 231 has a partially convex arc surface. The axis of rotation of the second movable member 231 relative to the bracket 21 coincides with the axis of the partially outer cylindrical surface. The arc surface is provided with a plurality of meshing teeth 2312 continuously arranged along the circumference of the arc surface. The damping component 30 includes a damper 32 and a rack 31. The rack 31 is slidably connected to the bracket 21 along the first direction Y. The rack 31 meshes with the meshing teeth 2312. Along the straight direction of the rack 31, the rack 31 is configured to be driven to make linear motion relative to the bracket 21. The movable end of the damper 32 abuts against one end of the rack 31 in the length direction.

[0122] As an example, the bracket 21 is provided with a cover plate 27, which is detachably connected to the bracket 21. Specifically, it can be one or both of snap-fit ​​or screw connection, and together with the bracket 21, it defines a guide groove. The length direction of the guide groove can be the same as the first direction Y. The rack 31 and the damper 32 are both disposed in the guide groove, and the damper 32 abuts against the end of the rack 31.

[0123] The damper 32 can be a unidirectional damper 32. In other examples, the damping component 30 can be a flexible telescopic rod, which can be one of the structures listed above.

[0124] As an example, the second slot 2311 can generally be a U-shaped slot.

[0125] During the process of the second retaining part 12 engaging with the second retaining slot 2311, the second retaining part 12 drives the second movable member 231 to rotate relative to the bracket 21. The rotation of the second movable member 231 drives the rack 31 to move along its own linear direction, thereby compressing the damper 32. The damper 32 provides a reverse damping force to slow down the speed at which the second retaining part 12 enters the second retaining slot 2311, thereby reducing the noise generated by the collision between the door 300 and the housing 200 when the door is closed, and also reducing the noise of the retaining member 10 engaging with the locking assembly 20. In other examples, the rack 31 structure can be omitted, one end of the damper 32 abuts against the second movable member 231, and the other end of the damper 32 is hinged to the bracket 21.

[0126] In some embodiments of this application, please refer to Figure 2 , Figures 3A-3C The second movable member 231 includes a rotating hook arm 2313, and the locking assembly 20 also includes a blocking limit member 25. The blocking limit member 25 is located on the side of the second movable member 231 with the second slot 2311. The blocking limit member 25 is movably mounted on the bracket 21. The blocking limit member 25 has a limiting slot 251. When the second holding part 12 is located outside the second through hole 2114, the limiting slot 251 engages with the rotating hook arm 2313 to limit the rotation of the second movable member 231 relative to the bracket 21.

[0127] As an example, the second movable member 231 is also provided with a first guide surface 23112, which is connected to the groove wall of the second slot 2311. During the engagement process of the second holding part 12, the second holding part 12 first abuts against the first guide surface 23112. The second holding part 12 is driven by external force to make the second movable member 231 rotate. At this time, the position of the second slot 2311 relative to the second holding part 12 changes, and slides into the second slot 2311 under the guidance of the first guide surface 23112, and finally moves into the second slot 2311. At the same time, the second elastic member 232 maintains the engagement state under its force.

[0128] As an example, the second slot 2311 has a clearance portion 23111, which allows a portion of the second holding portion 12 to have a certain amount of room to move within the second slot 2311 during the engagement process, thereby reducing the probability of interference during engagement. A portion of the clearance portion 23111 may connect with the aforementioned first guide surface 23112. In other examples, the width of the second slot 2311 is slightly larger than the width of the second holding portion 12 (the dimension of the portion of the second holding portion 12 located within the second slot 2311 after engagement along the engagement direction X), to further reduce the probability of interference during engagement.

[0129] As an example, the second holding part 12 has a hook-shaped structure, including a hook rod 122 and a hook head 121. The hook head 121 is connected to the hook rod 122, which can be welded or integrally formed. A clearance groove 113 is formed between the hook head 121 and the hook rod 122 to accommodate at least a partial rotation of the hook arm 2313 during the locking process. Along the direction from the hook head 121 to the hook rod 122, the cross-sectional area of ​​the hook rod 122 increases progressively, which can improve the strength of the hook rod 122 and reduce stress concentration of the hook rod 122 during the locking process.

[0130] The limiting slot 251 can be, but is not limited to, a U-shaped slot, a trapezoidal slot, or a rectangular slot, etc., and can be designed according to actual needs.

[0131] The blocking and limiting member 25 can be slidably connected to the bracket 21, and the blocking and limiting member 25 can also be rotatably connected to the bracket 21.

[0132] As an example, the blocking and limiting member 25 is slidably connected to the bracket 21 along the first direction Y. Specifically, the bracket 21 is provided with a guide groove extending along the first direction Y, the blocking and limiting member 25 is disposed in the guide groove, and is capable of moving along the first direction Y. A spring or elastic telescopic rod is provided between the guide groove and the blocking and limiting member 25.

[0133] As an example, the end of the bracket 21 receiving the holding member 10 is the snap-in end 2111. The blocking and limiting member 25 is provided with a second guide surface 252 on the side facing the second through hole 2114. Along the direction from the second holding part 12 to the first holding part 11, the size of the second guide surface 252 to the snap-in end 2111 increases in the snap-in direction X. During the snap-in process of the second holding part 12, the blocking and limiting member 25 is driven by the second holding part 12 and can squeeze the second guide surface 252 so that the limiting slot 251 moves away from the rotating hook arm 2313, thereby allowing the limiting slot 251 to separate from the rotating hook arm 2313, thereby releasing the restriction on the rotation of the second movable member 231, and finally realizing the snap-in of the second holding part 12.

[0134] As an example, the blocking and limiting member 25 is provided with a first magnet and a second magnet on the side opposite to the second movable member 231. The first magnet is connected to the blocking and limiting member 25 and can also be part of the blocking and limiting member 25. The second magnet is fixed to the bracket 21 and can also be part of the bracket 21. The first magnet and the second magnet are arranged opposite each other and their magnetic poles face each other. The repulsive force of the first magnet and the second magnet can keep the rotating hook arm 2313 in a locked state with the limiting slot 251.

[0135] By rotating the hook arm 2313 and setting the limit slot 251, the probability of the second moving part 231 being abnormally triggered can be reduced, thereby improving the reliability of the second holding part 12 engaging.

[0136] In some embodiments of this application, please refer to Figures 3A-3C The blocking and limiting member 25 is rotatably connected to the bracket 21. The locking assembly 20 also includes a fourth elastic member 26. The fourth elastic member 26 is located on the side of the blocking and limiting member 25 away from the second movable member 231. The fourth elastic member 26 abuts against the bracket 21 and the blocking and limiting member 25 respectively. When the rotating hook arm 2313 is in the latching state, the elastic force of the fourth elastic member 26 can cause the limiting slot 251 to remain in the latching state with the rotating hook arm 2313.

[0137] The fourth elastic element 26 includes a compression spring, an elastic telescopic rod, or a torsion spring.

[0138] As an example, the fourth elastic element 26 is a torsion spring. The fourth elastic element 26 can be set on the rotating shaft that rotatably connects the blocking and limiting member 25 and the bracket 21, or it can be not set on the rotating shaft, but one end of the fourth elastic element 26 abuts against the blocking and limiting member 25 and the other end abuts against the bracket 21, and the fourth elastic element 26 is located on the side of the blocking and limiting member 25 away from the second movable member 231.

[0139] As an example, the fourth elastic element 26 is a second compression spring. The second compression spring is located on the side of the blocking limit member 25 away from the second movable member 231 and is offset from the axis of rotation of the blocking limit member 25 and the bracket 21. One end of the second compression spring abuts against the bracket 21, and the other end abuts against the blocking limit member 25. Under the elastic force of the second compression spring, the blocking limit member 25 tends to rotate toward the second movable member 231 so as to maintain the locking state of the blocking limit member 25.

[0140] The fourth elastic element 26 enables the limiting slot 251 and the rotating hook arm 2313 to remain engaged, thereby reducing the probability of the second movable element 231 being abnormally triggered and further improving the reliability of the engagement between the second holding part 12 and the second slot 2311. Furthermore, by overcoming the elastic force of the fourth elastic element 26, the limiting slot 251 and the rotating hook arm 2313 can be disengaged, facilitating the engagement operation between the second holding part 12 and the second slot 2311. At the same time, during the engagement process, it can also provide damping force to the second holding part 12 to slow down the speed of entering the second slot 2311.

[0141] In some embodiments of this application, the volume of the first holding part 11 is smaller than the volume of the second holding part 12.

[0142] Therefore, the first through hole 2121 can be made smaller than the second through hole 2114 to reduce the entry of foreign objects into the first through hole 2121, thereby improving the reliability of the first holding part 11 engaging.

[0143] In some embodiments of this application, the dimension of the first holding part 11 along the second direction is smaller than the dimension of the second holding part 12 along the second direction, and the second direction is the same as the rotation axis of the second movable member 231 relative to the bracket 21.

[0144] Therefore, the first through hole 2121 can be made into a flat hole to form a narrow slit structure, thereby further reducing the entry of foreign objects into the first through hole 2121 and improving the reliability of the first holding part 11.

[0145] In some embodiments of this application, the size of the first through hole 2121 along the second direction is greater than 0 and less than or equal to 3 mm, and / or the size of the second through hole 2114 along the second direction is greater than or equal to 3 mm and less than or equal to 9 mm.

[0146] Therefore, the first through hole 2121 can form a small hole or narrow slit to further reduce the entry of foreign objects and reduce the impact of foreign objects on the locking process; the second through hole has a size range of 3mm-9mm along the second direction, which can prevent fingers from being inserted into the second through hole 2114. On the one hand, it can prevent fingers from being pinched when closing the door, and on the other hand, it can prevent fingers from accidentally triggering the second moving part 231, thereby improving the reliability of the locking.

[0147] This improves the reliability of the engagement between the first holding part 11 and the second holding part 12.

[0148] According to an embodiment of this application, a cooking appliance 1000 is provided, including a housing 200, a door 300, and a door lock device 100 as described in the above embodiment. The housing 200 has an interior cavity, and a doorway communicating with the cavity is provided at the front end of the housing 200. The door 300 is configured to close to the doorway, and one end of the door 300 is pivotally connected to the housing 200. A retaining member 10 is installed on the door 300, and a first retaining portion 11 extends from the side of the door 300 toward the doorway. A locking assembly 20 is installed inside the housing 200. When the door 300 is closed to the doorway, the first retaining portion 11 is in a first locked state; when the door 300 is open, the first retaining portion 11 is in a first unlocked state.

[0149] Cooking appliances 1000 can include, but are not limited to, microwave ovens or electric ovens.

[0150] A cavity is a space used for cooking food.

[0151] The retaining element 10 can be installed on the door body 300 by means of screws, welding or riveting.

[0152] Taking a microwave oven as an example of a cooking appliance 1000, the first latching part 11 and the second latching part 12 are spaced vertically. During the closing process of the microwave oven, the first latching part 11 and the second latching part 12 are engaged with the locking component 20, which can improve the reliability of closing the door.

[0153] Since the cooking appliance 1000 includes all the technical features of the door lock device 100 described above, and has the same effect as described above, it will not be repeated here.

[0154] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application, and they should all be covered within the scope of the claims and specification of this application. In particular, as long as there is no structural conflict, the various technical features mentioned in the embodiments can be combined in any way. This application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
