[0004] In the related art, a cooking appliance has a cavity and a door body, the door body is rotationally installed on the cavity. The door body can be opened or closed under the action of an external force. In order to improve the safety of the cooking appliance during operation, for example, to prevent the cooking appliance from starting to work when the door body has not been completely closed, a catch is generally provided on the door body, and the catch is movably connected to the door body by a spring. The cavity of the cooking appliance is provided with a door lock mechanism, the door lock mechanism has a bracket, the bracket forms an inclined clamping portion, and the catch cooperates with the clamping portion to ensure that the door body can be completely closed to the cavity.

[0005] During the closing process of the door body, the catch overcomes the pulling force of the spring and the friction force between the catch and the clamping portion, and climbs from the low slope section of the clamping portion to the high slope section. After the catch passes over the high slope section of the clamping portion, under the action of the restoring force of the spring, the catch hooks the high slope section and is clamped with the clamping portion, so that the door body is locked with the cavity. However, in actual operation, at the moment when the catch passes over the high slope section of the clamping portion, the friction force between the catch and the clamping portion, and the resistance of the spring to the catch disappear. At this time, due to the inertia of the user's operation, the user continues to apply a pushing force to the door body, or the door body continues to move due to inertia, so that the door body collides with the cavity and causes a large noise.

[0065] Referring to FIGS. 1 and 2, the present application discloses a cooking appliance 200, which includes but is not limited to a microwave oven, a steam oven, an electric oven, etc. The cooking appliance 200 includes a cavity 210, a door body 220, and a door lock device 100. The cavity 210 is formed with an opening, and the door body 220 is installed at the opening of the cavity 210. The door body 220 is rotationally connected with the cavity 210 to open or close the opening of the cavity 210. For example, the door body 220 can be rotationally connected with the cavity 210 by a hinge. The door lock device 100 is connected between the cavity 210 and the door body 220 to realize the opening and closing of the door body 220 relative to the cavity 210.

[0066] Referring to FIGS. 3-6, in some embodiments, the door lock device 100 includes a bracket 10, a clamping member 20, a rotating member 30, and a locking assembly 40. The bracket 10 is configured to be installed on the cavity 210. The clamping member 20 is configured to be fixed on the door body 220. The door body 220 is rotationally connected with the cavity 210. The rotating member 30 is installed on the bracket 10 and is capable of rotating relative to the bracket 10. The rotating member 30 is configured to rotate between a first position and a second position. During the process that the clamping member 20 pushes the rotating member 30 to rotate from the first position to the second position, the rotating member 30 is capable of being clamped with the clamping member 20 to drive the door body 220 to close. The locking assembly 40 is installed on the bracket 10. The locking assembly 40 is configured to lock or unlock the rotating member 30 when the rotating member 30 is in the second position. When the rotating member 30 is locked, the rotating member 30 is fixed relative to the bracket 10. When the rotating member 30 is unlocked, the rotating member 30 is capable of rotating relative to the bracket 10.

[0067] In this way, the rotating piece 30 can be clamped with the clamping piece 20 to drive the door body 220 to close, so that the process of closing the door body 220 does not need to be manually continuously applied with a pushing force, so that the process of closing the door body 220 is controllable, and noise generated is small. When the rotating piece 30 is in the second position, the rotating piece 30 is clamped with the clamping piece 20, the locking assembly 40 locks the rotating piece 30, and the rotating piece 30 is fixed relative to the support 10, that is, the rotating piece 30 cannot rotate relative to the support 10, so that the door body 220 is difficult to rotate relative to the cavity 210 through the clamping piece 20, and the difficulty of opening the door body 220 when closing the door body 220 is increased, so that the door lock device 100 can realize a child lock function.

[0068] That is, the support 10 of the door lock device 100 in the embodiment of the application cancels the clamping part fixedly arranged on the support relative to the related art solution, and the clamping piece 20 needs to overcome smaller resistance in the process of closing the door body 220, so that the user does not need to apply a large pushing force when closing the door, and does not need to continuously apply the pushing force, so that the collision force between the door body 220 and the cavity 210 is lighter, and noise generated is smaller.

[0069] Specifically, the support 10 is a carrier of the locking assembly 40 and other parts, and the support 10 can be installed on the cavity 210 through screws and other fasteners. In order to meet the installation position, structure and other requirements of different parts, the support 10 is generally designed to be irregular.

[0070] The clamping piece 20 can be installed on the door body 220 through welding, threaded connection, clamping and the like, so that the clamping piece 20 is fixed with the door body 220.

[0071] It should be noted that the rotating piece 30 is clamped or unclamped with the clamping piece 20 in the process of opening and closing the door body 220, so that the rotating piece 30 rotates relative to the support 10 with the opening and closing of the door body 220, or in other words, after the rotating piece 30 is limited to rotate, the door body 220 cannot be opened or closed.

[0072] Therefore, after the rotating piece 30 is clamped with the clamping piece 20, the locking assembly 40 is used to limit the rotating piece 30 to rotate relative to the support 10, so that the door body 220 cannot be opened, thereby increasing the complexity of opening the door body 220 and improving the safety of using the cooking appliance 200.

[0073] In the embodiment of the application, the opening of the cavity 210 refers to the area around the cavity 210, and the opening of the cavity 210 is used to put food into or take food out of the cavity 210.

[0074] Referring to FIGS. 4-7, in some embodiments, the locking assembly 40 includes a locking member 41 and a driving component 42. The locking member 41 is rotatably arranged on the bracket 10 and is movable between a locked position and an unlocked position. When the locking member 41 is in the locked position, the locking member 41 locks the rotating member 30. When the locking member 41 is in the unlocked position, the locking member 41 unlocks the rotating member 30. The driving component 42 is arranged on the bracket 10 and is configured to drive the locking member 41 to rotate from the unlocked position to the locked position.

[0075] In this way, the driving component 42 drives the locking member 41 to rotate from the unlocked position to the locked position, so that the locking member 41 locks the rotating member 30 in the locked position, making it difficult for the rotating member 30 to rotate relative to the bracket 10, and thus making it difficult for the door body 220 to open, and keeping the door body 220 in the closed state. The locking member 41 and the driving component 42 cooperate to make it easy to realize the function of the locking assembly 40 to lock the rotating member 30.

[0076] In addition, the locking member 41 is rotatably arranged on the bracket 10, so that the driving component 42 can be arranged on one side of the locking member 41 in the circumferential direction. The driving component 42 can be flexibly arranged on the bracket 10 to make full use of the space of the bracket 10, so that the structure of the door lock device 100 is more compact.

[0077] Specifically, referring to FIGS. 6 and 7, for example, the locking member 41 can be provided with an adapter hole 411, and the bracket 10 can be provided with an adapter shaft 11. The locking member 41 can be sleeved on the adapter shaft 11 through the adapter hole 411, so as to be rotatably connected with the bracket 10. When the locking member 41 is in the locked position, the locking member 41 is at least partially located in the movement space of the rotating member 30, and the locking member 41 stops the rotating member 30, so as to lock the rotating member 30.

[0078] Similarly, when the locking member 41 unlocks the rotating member 30, the locking member 41 is located outside the rotating space of the rotating member 30 or avoids the rotation of the first limiting member 30. The locking member 41 does not limit the movement of the rotating member 30, so that the rotating member 30 can move relative to the bracket 10, thereby unlocking the rotating member 30.

[0079] The driving component 42 includes, but is not limited to, an electromagnetic component, a pneumatic component, an electro-deformation component, an elastic component, and the like. The driving component 42 can be installed on the bracket 10 by means of a fastener such as a screw.

[0080] In the embodiments of the present application, the unlocked position of the locking member 41 is, for example, the position shown in FIG. 8, and the locked position of the locking member 41 is, for example, the position shown in FIG. 9.

[0081] Please refer to FIGS. 7-9, in some embodiments, the locking member 41 can rotate from the locked position to the unlocked position under the action of gravity in the case that the driving member 42 eliminates the driving action on the locking member 41. In other words, the locking member 41 can unlock the rotating member 30 under the action of gravity, so that the rotating member 30 can rotate relative to the support 10, and the door body 220 can be opened. In this way, the cooking appliance 200 can be opened even in the case of power failure, and the convenience of using the cooking appliance 200 is improved.

[0082] Please refer to FIGS. 5-7, in some embodiments, the driving member 42 and the rotating member 30 are respectively arranged on the two sides of the support 10 opposite to each other, and the locking member 41 is arranged through the support 10. In this way, the installation positions of the driving member 42 and the rotating member 30 can make full use of the space of the support 10, the compactness of the door lock device 100 is improved, and the door lock device 100 is more miniaturized.

[0083] Please refer to FIGS. 7-9, in some embodiments, the locking member 41 comprises a rotating portion 412, an abutting portion 413 and a pushing portion 414. The rotating portion 412 is rotatably arranged on the support 10, the abutting portion 413 and the pushing portion 414 are arranged along the circumference of the rotating portion 412, the support 10 is provided with a guide hole 14 for avoiding the movement of the abutting portion 413, the abutting portion 413 is arranged through the guide hole 14, the abutting portion 413 can lock the rotating member 30 when the abutting portion 413 abuts against the rotating member 30, and the driving member 42 drives the locking member 41 to rotate through the pushing portion 414.

[0084] In this way, the rotating portion 412, the abutting portion 413 and the pushing portion 414 cooperate with each other, so that the locking member 41 can lock or unlock the rotating member 30. Specifically, the rotating portion 412 can be similar to a cylinder, and the rotating portion 412 can be sleeved on the adapter shaft 11 of the support 10, so that the locking member 41 can rotate relative to the support 10 through the rotating portion 412.

[0085] The abutting portion 413 comprises a columnar structure, and the abutting portion 413 can be used to abut against the rotating member 30 to lock the rotating member 30. The pushing portion 414 can be irregularly shaped, and the pushing portion 414 can form a torque on the locking member 41 under the action of the driving member 42, so that the locking member 41 can rotate.

[0086] In addition, the pushing portion 414 can rotate the locking member 41 under the action of gravity, so that the locking member 41 can rotate from the locked position to the unlocked position under the action of gravity in the case that the driving member 42 eliminates the driving action on the locking member 41.

[0087] In order to make the structure of the locking member 41 more stable and easy to manufacture, the locking member 41 can be an integral structure, for example, the locking member 41 can be a plastic member formed by an injection molding process.

[0088] It can be understood that, as the locking member 41 rotates relative to the bracket 10, the movement track of the abutting portion 413 of the locking member 41 is in the shape of an arc, and in order to avoid the abutting portion 413, the guide hole 14 of the bracket 10 is also in the shape of an arc, so that the bracket 10 does not interfere with the movement of the abutting portion 413.

[0089] It should be noted that the abutting portion 413 abuts against the rotating member 30, which means that the abutting portion 413 contacts the rotating member 30, for example, the abutting portion 413 is located in the internal space of the rotating member 30 and contacts the rotating member 30, or means that there is a small gap between the abutting portion 413 and the rotating member 30, which is sufficient to limit the door body 220 from being pulled open after the rotating member 30 rotates by a small angle.

[0090] Please refer to FIGS. 8-10, in some embodiments, the rotating member 30 includes a rotating portion 34, a connecting portion 35, and a blocking rib 36, the rotating portion 34 is rotationally connected with the bracket 10, the connecting portion 35 is connected with the rotating portion 34, and the blocking rib 36 is connected with the edge of the rotating portion 34, the blocking rib 36 and the connecting portion 35 jointly form a movable space 37, and the blocking rib 36 is provided with a gap 361 communicating with the movable space 37;

[0091] In the case that the rotating member 30 is in the second position, the abutting portion 413 extends into the movable space 37, and the abutting portion 413 abuts against the blocking rib 36 in the case that the locking member 41 is in the locked position;

[0092] The abutting portion 413 is on the movement track of the gap 361 in the case that the locking member 41 is in the unlocked position, and the gap 361 passes through the abutting portion 413 in the process that the rotating member 30 rotates from the second position to the first position.

[0093] In this way, the abutting portion 413 and the blocking rib 36 cooperate with each other to lock the rotating member 30, and in addition, the abutting portion 413 and the gap 361 cooperate to unlock the rotating member 30.

[0094] Specifically, the rotating portion 34 can be in the shape of a cylinder and is installed on the bracket 10, the connecting portion 35 is in the shape of a sector, and the connecting portion 35 is formed with a clamping groove 33, in the process that the door body 220 is closed, the clamping member 20 can be clamped into the clamping groove 33, and after the door body 220 is closed, the clamping member 20 remains clamped in the clamping groove 33.

[0095] The blocking rib 36 is in the shape of a strip and extends along the edge of the connecting portion 35, and the gap 361 is a hollow part of the blocking rib 36, and in the process that the rotating member 30 rotates, the gap 361 can pass through the abutting portion 413, so that the abutting portion 413 is located in the movable space 37 of the rotating member 30 or outside the movable space 37.

[0096] Please refer to FIG. 8 and FIG. 9, in some embodiments, the driving component 42 comprises an electromagnetic component 421 and a push rod 422, the push rod 422 is arranged in the electromagnetic component 421, and the electromagnetic component 421 is used to drive the push rod 422 to move, so that the push rod 422 abuts against and drives the locking piece 41 to rotate from the unlocking position to the locking position.

[0097] In this way, the driving component 42 drives the push rod 422 to move by electromagnetic mode, so that the rotation of the locking piece 41 is controlled more easily. For example, when the electromagnetic component 421 is powered, the push rod 422 can move towards the locking piece 41, so as to push the locking piece 41 to rotate.

[0098] Specifically, the push rod 422 can be made of a magnetic material, that is, the push rod 422 is a magnetic piece. The magnetic piece comprises a material containing iron and other elements. The magnetic piece can be a permanent magnet or a non-permanent magnet. After the electromagnetic component 421 is powered, the electromagnetic component 421 generates a magnetic force, so that the electromagnetic component 421 and the push rod 422 are attracted or repelled, thereby making the push rod 422 move. The push rod 422 abuts against and pushes the pushing part 414 during the movement, so that the locking piece 41 rotates.

[0099] Please refer to FIG. 3, FIG. 5 and FIG. 7, in some embodiments, the door lock device 100 further comprises a damping piece 110, the damping piece 110 comprises a first buffering part 111 and a second buffering part 112 rotationally connected with the first buffering part 111, the first buffering part 111 is installed on the support 10, and the second buffering part 112 at least partially extends into the rotating piece 30. During the rotation of the rotating piece 30, the first buffering part 111 rotates relative to the second buffering part 112, so as to slow down the rotation speed of the rotating piece 30 through the damping between the first buffering part 111 and the second buffering part 112, thereby slowing down the closing speed of the door body 220.

[0100] The first buffering part 111 and the second buffering part 112 of the damping piece 110 are two mutually rotating parts. The first buffering part 111 and / or the second buffering part 112 can be provided with viscous liquid, which can provide resistance, so that the first buffering part 111 and the second buffering part 112 have damping during mutual rotation.

[0101] The first buffering part 111 can be fixed on the support 10 in a manner of interference fit, threaded connection, clamping connection, etc., and the second buffering part 112 can also be installed in the rotating piece 30 in a manner of interference fit, threaded connection, clamping connection, etc. The second buffering part 112 can entirely extend into the rotating piece 30, or can partially extend into the rotating piece 30.

[0102] In some embodiments, the damping member 110 can be a one-way damper, which can slow down the closing speed of the door body 220 when the door body 220 is closing, and does not provide damping when the door body 220 is opening, so as not to hinder the opening of the door body 220, thereby reducing the collision between the door body 220 and the cavity 210 when the door body 220 is closing, and reducing noise; when the door body 220 is opening, the damping member 110 does not slow down the opening speed of the door body 220, which is more labor-saving and improves user experience.

[0103] Referring to FIGS. 7 and 10, in some embodiments, the rotating member 30 is provided with a mounting hole 31, one end of the second buffer portion 112 is inserted into the mounting hole 31, and the second buffer portion 112 cooperates with the hole wall of the mounting hole 31 to apply a buffer force to the rotating member 30. In this way, the mounting hole 31 can make the rotating member 30 and the second buffer portion 112 have at least partially overlapping space, so that the second buffer portion 112 cooperates with the rotating member 30 more compactly.

[0104] Specifically, the mounting hole 31 can be a non-circular hole, so that after the one end of the second buffer portion 112 is inserted into the mounting hole 31, the second buffer portion 112 does not rotate relative to the rotating member 30 along the circumference of the mounting hole 31, so that the second buffer portion 112 moves synchronously with the rotating member 30.

[0105] Of course, the mounting hole 31 can also be a circular hole, at this time, the one end of the second buffer portion 112 can be interference fit with the mounting hole 31, or limited from rotating relative to the mounting hole 31 by a connecting key or the like.

[0106] Referring to FIGS. 5, 7 and 10, in some embodiments, the rotating member 30 is used to rotate between a first position and a second position, and the rotating member 30 is driven by the clamping member 20 to close the door body 220 during the rotation of the rotating member 30 from the first position to the second position;

[0107] The hole wall of the mounting hole 31 is formed with a stop portion 32, and when the rotating member 30 is located at the first position, the one end of the second buffer portion 112 is spaced apart from the stop portion 32, and after the rotating member 30 rotates by a predetermined angle from the first position to the second position, the one end of the first buffer portion 111 cooperates with the stop portion 32, so as to slow down the rotating speed of the rotating member 30.

[0108] That is to say, in the initial stage of the closing process of the door body 220, one end of the second buffer portion 112 is spaced apart from the stop portion 32, and the first buffer portion 111 and the first rotating member 30 can relatively rotate. At this time, the damping member 110 does not have a damping effect on the first rotating member 30. After the rotating member 30 rotates by a preset angle from the first position to the second position, one end of the second buffer portion 112 abuts against the stop portion 32, so that the rotating member 30 and the second buffer portion 112 can synchronously rotate relative to the support 10. At this time, the damping member 110 has a damping effect on the rotating member 30, so as to slow down the rotating speed of the rotating member 30, and further slow down the closing speed of the door body 220.

[0109] Specifically, the stop portion 32 is, for example, a protrusion protruding from the hole wall of the mounting hole 31 to the center of the mounting hole 31. The side surface of the protrusion can abut against one end of the first buffer portion 111, so that the rotating member 30 and the second buffer portion 112 synchronously rotate.

[0110] In some embodiments, the preset angle can be 5-10°, for example, the preset angle can be 5°, 8°, 10°, and the like. That is to say, after the rotating member 30 rotates by the preset angle from the first position to the second position, the damping member 110 starts to have a damping effect on the rotating member 30.

[0111] Referring to FIG. 7, in some embodiments, the support 10 is provided with an assembly hole 13, and the first buffer portion 111 is at least partially arranged in the assembly hole 13. In this way, the first buffer portion 111 is easy to be mounted on the support 10, and the structure between the damping member 110 and the support 10 can be more compact.

[0112] Referring to FIG. 3, FIG. 5 and FIG. 7, in some embodiments, the door lock device 100 comprises a first elastic member 50, the first elastic member 50 is connected between the support 10 and the rotating member 30, and the first elastic member 50 can apply an elastic force to the rotating member 30 to make the rotating member 30 rotate when the rotating member 30 cooperates with the clamping member 20, so as to drive the door body 220 to close through the clamping member 20.

[0113] In this way, the first elastic member 50 can make the door body 220 automatically close when the rotating member 30 cooperates with the clamping member 20, and the closing process of the door body 220 is relatively labor-saving, thereby improving the user experience. In addition, the elastic force applied by the first elastic member 50 to the rotating member is controllable, so that the collision between the door body 220 and the cavity 210 in the closing process is relatively light, and the noise generated is relatively small. For example, the first elastic member 50 can drive the rotating member 30 to rotate through pushing, pulling or other medium.

[0114] Referring to FIGS. 3, 5 and 7, in some embodiments, the first elastic member 50 includes a torsion spring 51, a first end 511 of the torsion spring 51 being connected to the bracket 10, and a second end 512 of the torsion spring 51 being connected to the rotating member 30.

[0115] When the second end 512 of the torsion spring 51 is located on a first side of a line 101 connecting the rotating center of the rotating member 30 and the first end 511 of the torsion spring 51, the torsion spring 51 applies a pushing force to the rotating member 30 in a direction of the first side.

[0116] When the second end 512 of the torsion spring 51 is located on a second side of the line 101, the torsion spring 51 applies a pushing force to the rotating member 30 in a direction of the second side, the first side and the second side being located on opposite sides of the line 101.

[0117] In this way, the torsion spring 51 stores energy during the opening of the door body 220, and keeps the rotating member 30 in a tendency of rotating in the first direction after the opening of the door body 220, so as to keep the rotating member 30 in the first position. The torsion spring 51 can release the stored energy and rotate the rotating member 30 in a second direction during the closing of the door body 220, so as to drive the door body 220 to close through the clamping member 20, the first direction being opposite to the second direction, and the first direction being a direction from the second position to the first position.

[0118] The rotating member 30 is driven to rotate by the torsion spring 51, so that the first elastic member 50 has a simple structure and is easy to implement, and the cost of the torsion spring 51 is low, which can reduce the cost of the first elastic member 50.

[0119] Specifically, when the rotating member 30 is kept in the first position, the bracket 10 provides support to the rotating member 30, so as to limit the rotating member 30 from continuously rotating in the first direction. For example, when the rotating member 30 is in the first position, the rotating member 30 can abut against the bracket 10.

[0120] As shown in FIG. 11, during the opening of the door body 220, the clamping member 20 is engaged with the rotating member 30, and the clamping member 20 can drive the rotating member 30 to rotate. At this time, the second end 512 of the torsion spring 51 is located on a side of the line 101 close to the door body 220, so that the torsion spring 51 applies an acting force to the rotating member 30 in the direction of the first direction. The acting force causes the rotating member 30 to act on the bracket 10, so as to keep the rotating member 30 in a static state.

[0121] As shown in FIG. 12 and FIG. 13, during the process of closing the door body 220, first, the door body 220 (or a handle on the door body 220) is pushed by a user, and under the condition that the user continuously pushes the door body 220 or due to inertia generated after the user pushes the door body 220, the door body 220 drives the clamping piece 20 to move in a closing direction, the clamping piece 20 extends into the support 10 and is clamped with the rotating piece 30, and along with the movement of the clamping piece 20, the clamping piece 20 drives the rotating piece 30 to rotate, after the rotating piece 30 rotates through a predetermined angle along the second direction, the second end 512 of the torsion spring 51 is located on a side of the line 101 that faces away from the door body 220, the torsion spring 51 releases the accumulated force and drives the rotating piece 30 to rotate along the second direction, so as to drive the rotating piece 30 to pull the clamping piece 20 and drive the door body 220 to rotate until completely closed.

[0122] It can be understood that the first direction of the rotating piece 30 is the direction in which the rotating piece 30 rotates during the process of switching the door body 220 from the closed state to the open state, for example, the counterclockwise direction shown in FIG. 7. It should be pointed out that in other embodiments, the first elastic member 50 can be a tensile spring, an electromagnetic driving component or the like.

[0123] Please refer to FIG. 7 and FIG. 11, in some embodiments, the door lock device 100 further comprises a second elastic member 60 arranged on the support 10, and under the condition that the rotating piece 30 is in the first position, the second elastic member 60 applies an elastic force to the rotating piece 30 in the direction of rotating to the second position.

[0124] In this way, the elastic force applied by the second elastic member 60 to the rotating piece 30 is opposite to the direction of the force or the component force applied by the torsion spring 51 to the rotating piece 30, and during the process of closing the door body 220, only a small pushing force needs to be provided to the door body 220, and under the boost of the second elastic member 60, the clamping piece 20 can easily overcome the resistance of the torsion spring 51 by driving the rotating piece 30, so that the door body 220 is more easily closed, and the user experience is improved.

[0125] Specifically, the second elastic member 60 includes but is not limited to a coil spring, an elastic block or the like, and the shape of the second elastic member 60 is, for example, a generally frustum shape. The second elastic member 60 can be fixed on the support 10 by means of clamping.

[0126] It should be pointed out that under the condition that the rotating piece 30 is in the first position, the acting force applied by the first elastic member 50 to the rotating piece 30 can be greater than the acting force applied by the second elastic member 60 to the rotating piece 30, so that the rotating piece 30 can be kept in the first position.

[0127] Please refer to FIG. 7 and FIG. 11, in some embodiments, the clamping piece 20 comprises a mounting portion 21, a first clamping portion 22 and a second clamping portion 23, the mounting portion 21 is used for fixing to the door body 220, the first clamping portion 22 and the second clamping portion 23 are both connected with the mounting portion 21 and are arranged at intervals, the first clamping portion 22 is located below the second clamping portion 23, the first clamping portion 22 is formed with a first clamping hook 2211, the rotating piece 30 is formed with a clamping groove 33, the rotating piece 30 can drive the door body to close through the first clamping portion 22 in the case that the first clamping hook 2211 and the clamping groove 33 are clamped.

[0128] In this way, the first clamping hook 2211 of the first clamping portion 22 is clamped with the clamping groove 33, so that the rotating piece 30 avoids disengaging from the clamping piece 20 in the rotating process, thereby improving the stability of the rotating piece 30 driving the door body 220 to close through the first clamping portion 22.

[0129] It should be noted that the clamping point of the first clamping hook 2211 and the clamping groove 33 can change with the rotation of the rotating piece 30, in the process of closing the door body 220, with the change of the clamping point, the first clamping hook 2211 and the clamping groove 33 remain clamped; in the process of opening the door body 220, with the change of the clamping point, the first clamping hook 2211 and the clamping groove 33 can be separated so that the door body 220 can be completely opened.

[0130] Please refer to FIG. 7 and FIG. 11, in some embodiments, the door lock device 100 further comprises a stop piece 70 which is rotatably arranged on the bracket 10, the second clamping portion 23 clamps with the stop piece 70 in the case that the door body 220 is closed.

[0131] In this way, the second clamping portion 23 clamps with the stop piece 70 in the case that the door body 220 is closed, which can improve the stability of the door body 220 closing and reduce the risk of the cooking appliance 200 being abnormally opened in normal working.

[0132] Specifically, as shown in FIG. 7, the stop piece 70 can be provided with a connecting hole 71, the bracket 10 can be provided with a pivot shaft 12, the stop piece 70 can be sleeved on the pivot shaft 12 through the connecting hole 71, so as to be rotatably connected with the bracket 10. The second clamping portion 23 is similar to a sheet, the second clamping portion 23 can be formed with a clamping hole 231, the stop piece 70 can be provided with a clamping block 72, the clamping hole 231 can cooperate with the clamping block 72, so that the second clamping portion 23 clamps with the stop piece 70.

[0133] In the embodiments of the present application, the mounting portion 21, the first clamping portion 22 and the second clamping portion 23 are in one-piece structure, for example, the mounting portion 21, the first clamping portion 22 and the second clamping portion 23 can be formed by die casting or the like. Of course, the mounting portion 21, the first clamping portion 22 and the second clamping portion 23 are in separate structure, and the first clamping portion 22 and the second clamping portion 23 can be fixed on the mounting portion 21 by screws or the like.

[0134] Referring to FIGS. 7 and 11, in some embodiments, the door lock device 100 further comprises a third elastic member 80, the third elastic member 80 connecting the stopper 70 and the bracket 10, and the third elastic member 80 being configured to apply a reset elastic force to the stopper 70 when the second clamping portion 23 is separated from the stopper 70.

[0135] In this way, the third elastic member 80 enables the stopper 70 to be reset after rotation, and in addition, the third elastic member 80 applies a pushing force to the door body 220 through the stopper 70, so that the door body 220 can be opened more labor-savingly, improving user experience.

[0136] Specifically, the third elastic member 80 includes but is not limited to torsion springs, tension springs, motor screw components and the like. When the third elastic member 80 is a torsion spring, one end of the torsion spring can be clamped into the bracket 10, and the other end can be clamped into the stopper 70.

[0137] Referring to FIGS. 3, 5 and 7, in some embodiments, the door lock device 100 can further comprise a micro switch 90 arranged on the bracket 10, the micro switch 90 being triggered when the door body 220 is in a closed state.

[0138] Referring again to FIGS. 1-3, in some embodiments, the cooking appliance 200 further comprises a control box 230 and a key 240. The control box 230 is arranged on the door body 220 or the cavity 210 and is electrically connected with the locking assembly 40. The key 240 is arranged on the control box 230. The key 240 can be a touch key or a mechanical key. The key 240 is configured to trigger an instruction, and the control box 230 can control the power-on state of the locking assembly 40 according to the unlocking instruction, so that the locking assembly 40 locks or unlocks the rotating member 30.

[0139] In summary, in one embodiment of the present application, the process of closing the door of the cooking appliance 200 is as follows:

[0140] Please refer to FIG. 7, FIG. 8, FIG. 11-FIG. 14, a pushing force is applied to the door body 220, the door body 220 moves towards the bracket 10, the first clamping part 22 pushes the rotating part 30 to rotate, the second clamping part 23 pushes the stop part 70 to rotate, after the rotating part 30 rotates through a predetermined angle in the second direction, the damping part 110 cooperates with the rotating part 30, the second end 512 of the torsion spring 51 is located on the side of the line 101 away from the door body 220, the torsion spring 51 releases the stored force and drives the rotating part 30 to rotate in the second direction, so that the rotating part 30 pulls the first clamping part 22 to continue to close the door body 220, and the damping part 110 can slow down the closing speed of the door body 220.

[0141] After the door body 220 is closed, the electromagnetic part 421 is powered on, the electromagnetic part 421 generates a magnetic force, so that the electromagnetic part 421 is attracted or repelled with the push rod 422, thereby moving the push rod 422, the push rod 422 can push the locking part 41 to rotate through the pushing part 414 in the moving process, so that the locking part 41 rotates from the unlocking position to the locking position to lock the rotating part 30, reducing the risk of directly opening the door body 220 by pulling, and ensuring the opening safety of the cooking appliance 200.

[0142] It can be understood that the opening process of the cooking appliance 200 is opposite to the closing process, as follows:

[0143] Please refer to FIG. 7, FIG. 8, FIG. 11-FIG. 14, after the cooking appliance 200 is completed, if it is not operated, the electromagnetic part 421 can be powered on for a preset time (for example, 30 minutes), during which the locking part 41 continuously locks the rotating part 30. If the key 240 is pressed, the key 240 sends an instruction to the control box 230, and after the control box 230 receives the unlocking instruction, the electromagnetic part 421 is powered off, at this time the electromagnetic part 421 has no force on the push rod 422. The locking part 41 rotates under the action of gravity and the gravity of the push rod 422 to move from the locking position to the unlocking position, so that the rotating part 30 is unlocked.

[0144] After the rotating part 30 is unlocked, the door body 220 is pulled, the first clamping part 22 drives the rotating part 30 to rotate, the second clamping part 23 drives the stop part 70 to rotate, during which the torsion spring 51 stores energy, after the first clamping part 22 and the rotating part 30 are disengaged, the second clamping part 23 and the stop part 70 are disengaged, the door body 220 is completely opened, the second end 512 of the torsion spring 51 is located on the side of the line 101 close to the door body 220, so that the torsion spring 51 applies a force to the rotating part 30 in the first direction, and the force makes the rotating part 30 remain in the first position.

[0145] The opening door mode of the cooking electric appliance is button type, pull door type or touch type, and the door can be opened without external force or with only a small external force. The overall operation is simple and convenient and only one step is needed, so that children can easily open the door body, and the cooking electric appliance has a safety hazard that children can open the door body by themselves and are scalded by high-temperature objects during use.

[0146] Therefore, as shown in FIGS. 2, 15 and 16, in some embodiments, the door locking device 100 includes a bracket 10, a first clamping part 22, a second clamping part 23, a locking assembly 40 and a rotating part 30. The bracket 10 is used to be installed at the opening of the cavity 210 and is provided with a limiting part 15. The rotating part 30 is arranged on the bracket 10. The first clamping part 22 is used to be fixed to the door body 220 and includes a first clamping hook 221 which can be clamped with the rotating part 30 when the door body 220 is closed. The second clamping part 23 is movably installed on the door body 220 and can move relative to the door body 220 during opening or closing of the door body 220. The second clamping part 23 includes a second clamping hook 232 which is adapted to be clamped with the limiting part 15 when the door body 220 is closed. The locking assembly 40 is installed on the bracket 10 and is used to lock or unlock the second clamping hook 232 when the door body 220 is closed. When the second clamping hook 232 is locked, the second clamping part 23 is fixed relative to the door body 220. When the second clamping hook 232 is unlocked, the second clamping part 23 can move relative to the door body 220.

[0147] Therefore, as shown in FIGS. 2, 15 and 16, in some embodiments, the door locking device 100 includes a bracket 10, a first clamping part 22, a second clamping part 23, a locking assembly 40 and a rotating part 30. The bracket 10 is used to be installed at the opening of the cavity 210 and is provided with a limiting part 15. The rotating part 30 is arranged on the bracket 10. The first clamping part 22 is used to be fixed to the door body 220 and includes a first clamping hook 221 which can be clamped with the rotating part 30 when the door body 220 is closed. The second clamping part 23 is movably installed on the door body 220 and can move relative to the door body 220 during opening or closing of the door body 220. The second clamping part 23 includes a second clamping hook 232 which is adapted to be clamped with the limiting part 15 when the door body 220 is closed. The locking assembly 40 is installed on the bracket 10 and is used to lock or unlock the second clamping hook 232 when the door body 220 is closed. When the second clamping hook 232 is locked, the second clamping part 23 is fixed relative to the door body 220. When the second clamping hook 232 is unlocked, the second clamping part 23 can move relative to the door body 220.

[0148] Specifically, the bracket 10 is a carrier of the locking assembly 40 and other components, and the bracket 10 can be mounted on the cavity 210 by screws and other fasteners. In order to meet the requirements of the mounting position, structure and the like of different components, the bracket 10 is generally designed to be irregular. The limiting portion 15 of the bracket 10 can be in a sheet-shaped structure, and the limiting portion 15 extends upwardly from one end close to the door body 220 and forms an inclined surface, which can enable the second clamping hook 232 to move up and down along the surface of the limiting portion 15. During the closing process of the door body 220, the second clamping hook 232 moves upwardly along the limiting portion 15, and after the second clamping hook 232 passes the highest point of the limiting portion 15, the second clamping hook 232 falls down and is clamped with the limiting portion 15.

[0149] It should be noted that in the embodiments of the present application, the upward direction is the direction in which the horizontal plane faces upward during normal use of the cooking appliance 200, and the downward direction is the direction in which the horizontal plane faces downward.

[0150] As shown in FIG. 16, the first clamping portion 22 can include a first mounting portion 222 and a first clamping hook 221, and the first clamping hook 221 and the first mounting portion 222 can be in an integrated structure. The first mounting portion 222 can be mounted on the door body 220 by welding, threaded connection, clamping and the like, so that the first clamping portion 22 is fixed with the door body 220. During the closing process of the door body 220, the first clamping hook 221 can move into the bracket 10 and extend into the bracket 10, and during the opening process of the door body 220, the first clamping hook 221 can move out of the bracket 10 and be separated from the bracket 10.

[0151] The second clamping portion 23 can include a second mounting portion 233 and a second clamping hook 232, and the second clamping hook 232 and the second mounting portion 233 can be in an integrated structure. The second mounting portion 233 can be movably mounted on the door body 220 by clamping and the like, so that the second clamping portion 23 can move relative to the door body 220. For example, a sliding groove can be provided on the door body 220 and extend along the height direction of the cooking appliance 200, and the second mounting portion 233 can be provided with a sliding block matched with the sliding groove. When the sliding block moves along the sliding groove, the second clamping portion 23 moves up and down relative to the door body 220.

[0152] It should be noted that the second clamping portion 23 moves relative to the door body 220 with the opening and closing of the door body 220, or in other words, after the movement of the second clamping portion 23 is limited, the door body 220 cannot be opened or closed. Therefore, after the second clamping portion 23 is clamped with the limiting portion 15, the movement of the second clamping portion 23 relative to the door body 220 is limited by the locking assembly 40, so that the door body 220 cannot be opened, thereby increasing the complexity of the opening of the door body 220 and improving the safety of the use of the cooking appliance 200.

[0153] In the embodiments of the present application, the opening of the cavity 210 refers to the area around the cavity 210, and the opening of the cavity 210 is used to put or remove food into or from the cavity 210.

[0154] Please continue to refer to FIGS. 16 and 17. In some embodiments, the locking assembly 40 includes a locking member 41 and a driving component 42. The locking member 41 is rotatably arranged on the bracket 10 and can move between a locked position and an unlocked position. When the locking member 41 is in the locked position, the locking member 41 locks the second hook 232. When the locking member 41 is in the unlocked position, the locking member 41 unlocks the second hook 232. The driving component 42 is arranged on the bracket 10, and the driving component 42 is used to drive the locking member 41 to rotate from the unlocked position to the locked position.

[0155] In this way, the driving component 42 drives the locking member 41 to rotate from the unlocked position to the locked position, so that the locking member 41 locks the second hook 232 in the locked position, making it difficult for the second hook 232 to move relative to the door body 220, making it difficult for the door body 220 to open, and keeping it in a closed state. The locking member 41 and the driving component 42 cooperate to make it easy to achieve the function of the locking assembly 40 locking the second hook 232. In addition, the locking member 41 is rotatably arranged on the bracket 10, so that the driving component 42 can be arranged on one side of the locking member 41 in the rotation direction. The driving component 42 can be flexibly arranged on the bracket 10 to make full use of the space of the bracket 10, so that the structure of the locking device is more compact.

[0156] Specifically, please refer to FIGS. 16 and 17. For example, the locking member 41 can be provided with a pivot hole 411, and the bracket 10 can be provided with a pivot shaft 12. The locking member 41 can be sleeved on the pivot shaft 12 through the pivot hole 411, so as to be rotatably connected with the bracket 10. When the locking member 41 is at least partially located in the movement space of the second hook 232, the locking member 41 stops the second hook 232, thereby locking the second hook 232. Similarly, when the locking member 41 unlocks the second hook 232, the locking member 41 is located outside the rotation space of the second hook 232, and the movement of the second hook 232 is not limited by the locking member 41. The second hook 232 can move relative to the door body 220, thereby unlocking the second hook 232.

[0157] The driving component 42 includes, but is not limited to, an electromagnetic component, a pneumatic component, an electro-deformation component, an elastic component, and the like. The driving component 42 can be installed on the bracket 10 by means of screws or other fasteners.

[0158] In the embodiments of the present application, the unlocked position of the locking member 41 is, for example, the position shown in FIG. 24, and the locked position of the locking member 41 is, for example, the position shown in FIG. 24.

[0159] Please refer to FIG. 15-FIG. 17, in some embodiments, the locking member 41 comprises a rotating portion 412, an abutting portion 413 and a pushing portion 414, the rotating portion 412 is rotatably arranged on the support 10, the abutting portion 413 and the pushing portion 414 are arranged along the circumference of the rotating portion 412, the abutting portion 413 locks the second hook 232 when the abutting portion 413 abuts against the second hook 232, the driving member 42 drives the locking member 41 to rotate through the pushing portion 414.

[0160] In this way, the rotating portion 412, the abutting portion 413 and the pushing portion 414 cooperate with each other, so that the locking member 41 can lock or unlock the second hook 232. Specifically, the rotating portion 412 can be similar to a cylinder, the rotating portion 412 can be sleeved on the pivot shaft 12 of the support 10, so that the locking member 41 rotates relative to the support 10 through the rotating portion 412. The abutting portion 413 is similar to a sheet structure, one end of the abutting portion 413 is connected with the rotating portion 412, and the other end is used for abutting against the second hook 232. The pushing portion 414 can be irregular, the pushing portion 414 forms a torque on the locking member 41 under the action of the driving member 42, so that the locking member 41 can rotate.

[0161] In order to make the structure of the locking member 41 more stable and easy to manufacture, the locking member 41 can be an integral structure, for example, the locking member 41 can be a plastic part formed by an injection molding process.

[0162] It should be pointed out that the abutting of the abutting portion 413 against the second hook 232 can mean that the abutting portion 413 contacts the second hook 232, for example, the abutting portion 413 is located directly above the second hook 232 and contacts the second hook 232, or can mean that there is a small gap between the abutting portion 413 and the second hook 232, which is sufficient to limit the door body 220 from being pulled open after the second hook 232 moves a small displacement.

[0163] Please refer to FIG. 15, FIG. 16 and FIG. 18, in some embodiments, the driving member 42 comprises an electromagnetic portion 421 and a push rod 422, the push rod 422 is arranged in the electromagnetic portion 421, the electromagnetic portion 421 is used to drive the push rod 422 to move, so that the push rod 422 abuts against and drives the locking member 41 to rotate from the unlocking position to the locking position.

[0164] In this way, the driving member 42 drives the push rod 422 to move in an electromagnetic manner, so that the locking member 41 rotates, so that the rotation control of the locking member 41 is more easily realized. For example, in the case that the electromagnetic portion 421 is powered, the push rod 422 can move towards the locking member 41, thereby pushing the locking member 41 to rotate.

[0165] Specifically, the push rod 422 can be made of a magnetic material, or in other words, the push rod 422 is a magnetic member. The magnetic member includes a material containing iron or other elements. The magnetic member can be a permanent magnet or a non-permanent magnet. After the electromagnetic part 421 is powered on, the electromagnetic part 421 generates a magnetic force, so that the electromagnetic part 421 is attracted or repelled to the push rod 422, thereby causing the push rod 422 to move. The push rod 422 abuts against the pushing part 414 during the movement, thereby causing the locking member 41 to rotate.

[0166] Referring to FIGS. 15, 16 and 18, in some embodiments, the driving component 42 further includes a fourth elastic member 423 connected to the electromagnetic part 421 and the push rod 422. The fourth elastic member 423 applies a reset elastic force to the push rod 422 when the locking member 41 is in the locked position. In this way, the fourth elastic member 423 can reset the push rod 422 after the electromagnetic part 421 drives the push rod 422 to move. In addition, the fourth elastic member 423 has a simple structure and low cost, making it easier to implement the function of moving the push rod 422 away from the locking member 41. For example, the fourth elastic member 423 can be a cylindrical coil spring. The fourth elastic member 423 can be sleeved on the push rod 422. The fourth elastic member 423 is in a compressed state when the locking member 41 is in the locked position. At this time, the fourth elastic member 423 can apply a pushing force to the push rod 422, so that the push rod 422 is reset without the electromagnetic part 421 driving the push rod 422. Of course, the fourth elastic member 423 can also be a torsion spring, a rubber elastic member or the like.

[0167] Referring to FIGS. 16 and 19, in some embodiments, the locking assembly 40 further includes a fifth elastic member 43 connected to the bracket 10 and the locking member 41. The fifth elastic member 43 applies a reset elastic force to the locking member 41 when the locking member 41 is in the locked position, so that the locking member 41 rotates from the locked position to the unlocked position.

[0168] In this way, the fifth elastic member 43 has a simple structure and low cost, making it easier to implement the function of returning the locking member 41 to the unlocked position. For example, the fifth elastic member 43 can include but is not limited to a cylindrical coil spring, a torsion spring, a rubber elastic member or the like.

[0169] Specifically, the fifth elastic member 43 can be connected to the pushing part 414 of the locking member 41 and the bracket 10. In one example, referring to FIGS. 16, 17 and 19, when the locking member 41 is in the unlocked position, the electromagnetic part 421 drives the push rod 422 to move after being powered on. The push rod 422 can move towards the locking member 41 and push the locking member 41 to rotate from the unlocked position to the locked position. At this time, the locking member 41 restricts the movement of the second clamping part 23.

[0170] When the electromagnetic part 421 is powered off, the fourth elastic part 423 moves the push rod 422 away from the locking part 41, so that the push rod 422 is separated from the locking part 41, and at the same time, the fifth elastic part 43 returns from the stretched state, thereby driving the locking part 41 to return from the locked position to the unlocked position. Under the cooperation of the electromagnetic part 421, the push rod 422, the fourth elastic part 423 and the fifth elastic part 43, the locking part 41 can reciprocate between the unlocked position and the locked position.

[0171] Referring to FIGS. 15, 16 and 19, in some embodiments, the door locking device 100 comprises a reset elastic part 120 connected to the bracket 10 and the second clamping part 23, and the reset elastic part 120 applies a downward reset force to the second clamping part 23.

[0172] Referring to FIGS. 16, 17 and 19, in some embodiments, the rotating part 30 is rotatably installed on the bracket 10.

[0173] Specifically, the rotating part 30 can comprise a rotating part 34 and a connecting part 35 connected to the rotating part 34, the rotating part 34 can be cylindrical and installed on the bracket 10, and the connecting part 35 is similar to a fan-shaped structure, the connecting part 35 is formed with a clamping groove 33, during the closing of the door body 220, the first clamping hook 221 can be clamped into the clamping groove 33, and after the door body 220 is closed, the first clamping hook 221 remains clamped in the clamping groove 33.

[0174] Referring to FIGS. 15, 16 and 19, in some embodiments, the door locking device 100 further comprises a first elastic part 50 connected to the bracket 10 and the rotating part 30, and the first elastic part 50 can apply an elastic force to the rotating part 30 to make the rotating part 30 rotate to drive the door body 220 to close through the first clamping part 22 when the rotating part 30 is clamped with the first clamping hook 221.

[0175] In this way, the first elastic part 50 can make the door body 220 automatically close when the rotating part 30 is clamped with the first clamping hook 221, and the closing process of the door body 220 is relatively labor-saving, which improves the user experience.

[0176] Referring to FIGS. 19-21, in some embodiments, the first elastic part 50 comprises a torsion spring 51, the first end 711 of the torsion spring 51 is connected to the bracket 10, and the second end 712 of the torsion spring 51 is connected to the rotating part 30, when the second end 712 of the torsion spring 51 is located on the first side of the line connecting the rotating center of the rotating part 30 and the first end 711 of the torsion spring 51, the torsion spring 51 applies a pushing force to the rotating part 30 towards the first side rotation;

[0177] When the second end 712 of the torsion spring 51 is located on the second side of the line 72 connecting the rotation center of the rotating member 30 and the first end 711 of the torsion spring 51, the torsion spring 51 applies a pushing force to the rotating member 30 in the direction of the second side, and the first side and the second side are located on the opposite sides of the line 72, respectively.

[0178] In this way, the torsion spring 51 stores energy during the opening of the door body 220 and keeps the rotating member 30 in the tendency of rotating in the first direction (e.g., the clockwise direction in FIG. 19) after the door body 220 is opened, so that the rotating member 30 abuts against the bracket 10; the torsion spring 51 can release the stored energy and make the rotating member 30 rotate in the second direction (e.g., the counterclockwise direction in FIG. 19) during the closing of the door body 220, so that the door body 220 is closed by the second clamping part 23, and the first direction is opposite to the second direction.

[0179] The rotating member 30 is driven to rotate by the torsion spring 51, so that the first elastic member 50 has a simple structure, is easy to implement, and the cost of the torsion spring 51 is low, so that the cost of the first elastic member 50 can be reduced.

[0180] As shown in FIG. 20, during the opening of the door body 220, the first clamping hook 221 is clamped with the rotating member 30, and the first clamping hook 221 can drive the rotating member 30 to rotate, at this time, the second end 712 of the torsion spring 51 is located on the side of the line 72 close to the door body 220, so that the torsion spring 51 applies a force to the rotating member 30 in the direction of the first direction, and the force makes the rotating member 30 abut against the bracket 10, so that the rotating member 30 is kept in the static state.

[0181] As shown in FIG. 22, during the closing of the door body 220, the first clamping hook 221 extends into the bracket 10 and is clamped with the rotating member 30, and as the first clamping hook 221 moves, the first clamping hook 221 drives the rotating member 30 to rotate, and after the rotating member 30 rotates in the second direction by a predetermined angle, the second end 712 of the torsion spring 51 is located on the side of the line 72 away from the door body 220, the torsion spring 51 releases the stored energy and makes the rotating member 30 rotate in the second direction, so that the rotating member 30 pulls the first clamping hook 221 to drive the door body 220 to rotate until it is completely closed.

[0182] It should be noted that the first direction of the rotating member 30 is the direction in which the rotating member 30 rotates during the process that the door body 220 switches from the closed state to the open state, for example, the counterclockwise direction shown in FIG. 19. It can be understood that in other embodiments, the first elastic member 50 can be a tensile spring, an electromagnetic driving component, or the like.

[0183] Referring to FIG. 15, FIG. 16 and FIG. 19, in some embodiments, the door locking device 100 further comprises a damping member 110 connected between the rotating member 30 and the bracket 10, which is configured to slow down the rotating speed of the rotating member 30 during the closing of the door body 220, so as to slow down the closing speed of the door body 220.

[0184] In this way, the damping member 110 slows down the closing speed of the door body 220, so as to reduce the collision between the door body 220 and the cavity 210 and reduce the noise. The damping member 110 can include, but is not limited to, a coil spring, a damper, etc. It can be understood that the damping member 110 can provide a resistance to the movement of the first hook 221, but the power provided by the first elastic member 50 is greater than the resistance of the damping member 110, so that during the movement of the door body 220 driven by the cooperation between the first hook 221 and the rotating member 30, the movement speed of the door body 220 is only slowed down, but the movement direction of the door body 220 is not changed.

[0185] In some embodiments, the damping member 110 can be a one-way damper, which can include two parts rotating relative to each other, one part of the one-way damper can be connected with the rotating member 30 and the other part can be connected with the bracket 10. During the closing of the door body 220, the one-way damper can slow down the closing speed of the door body 220, while during the opening of the door body 220, the one-way damper does not provide damping and does not hinder the opening of the door body 220, so as to reduce the collision between the door body 220 and the cavity 210 and reduce the noise when the door body 220 is closed; on the contrary, when the door body 220 is opened, the damping member 110 does not slow down the opening speed of the door body 220, which is more labor-saving and improves the user experience.

[0186] Referring again to FIG. 17, in some embodiments, the door locking device 100 can further comprise a micro switch 90 arranged on the bracket 10, which is triggered when the door body 220 is in the closed state.

[0187] Referring again to FIG. 1-FIG. 16, in some embodiments, the cooking appliance 200 further comprises a control box 230 and a key 240. The control box 230 is arranged on the door body 220 or the cavity 210 and is electrically connected with the locking assembly 40. The key 240 is arranged on the control box 230. The key 240 can be a touch key or a mechanical key. The key 240 is configured to trigger an instruction, and the control box 230 can control the power-on state of the locking assembly 40 according to the unlocking instruction, so as to lock or unlock the second hook 232 by the locking assembly 40.

[0188] In summary, in one embodiment of the present application, the closing process of the cooking appliance 200 is as follows:

[0189] Please refer to Figs. 19-24, a pushing force is applied to the door body 220, the door body 220 moves towards the bracket 10, the first clamping hook 221 pushes the rotating piece 30 to rotate, the second clamping hook 232 moves upwards along the limiting part 15, after the rotating piece 30 rotates through a predetermined angle in the second direction, the second end 712 of the torsional spring 51 is located on the side of the line 72 away from the door body 220, the torsional spring 51 releases the stored force and drives the rotating piece 30 to rotate in the second direction, so that the rotating piece 30 pulls the first clamping hook 221 to drive the door body 220 to continue to close, and the damping piece 110 can slow down the closing speed of the door body 220.

[0190] When the second clamping hook 232 moves over the highest end of the limiting part 15, the second clamping hook 232 moves downwards under the action of the reset elastic piece 120 and is clamped with the limiting part 15, at this time, the door body 220 is in a closed state. Further, after the door body 220 is closed, the electromagnetic part 421 is powered on, the electromagnetic part 421 generates a magnetic force, so that the electromagnetic part 421 is attracted or repelled with the push rod 422, so that the push rod 422 moves, the push rod 422 abuts against the pushing part 414 in the moving process, so that the locking piece 41 rotates from the unlocking position to the locking position to lock the second clamping hook 232, reduces the risk of directly opening the door body 220 by pulling, and ensures the opening safety of the cooking appliance 200. During the movement of the push rod 422 and the locking piece 41 driven by the electromagnetic part 421, the fourth elastic piece 423 and the fifth elastic piece 43 store energy.

[0191] It can be understood that the opening process of the cooking appliance 200 is opposite to the closing process, which is as follows:

[0192] Please refer to Figs. 19-24, after the cooking appliance 200 works, if it is not operated, the electromagnetic part 421 can be powered on for a preset time (for example, 30 minutes), during which the locking piece 41 continuously locks the second clamping hook 232. If the key 240 is pressed, the key 240 sends an instruction to the control box 230, and after the control box 230 receives the unlocking instruction, the electromagnetic part 421 is powered off, at this time, the electromagnetic part 421 has no force on the push rod 422. The push rod 422 moves away from the locking piece 41 under the action of the fourth elastic piece 423, in addition, the locking piece 41 moves from the locking position to the unlocking position under the action of the fifth elastic piece 43, so that the second clamping hook 232 is unlocked.

[0193] After the second hook 232 is unlocked, the door body 220 is pulled, the first hook 221 drives the rotating member 30 to rotate, in this process, the torsion spring 51 stores energy, the second hook 232 moves upward and passes the highest end of the limiting part 15, and then is disengaged from the limiting part 15, and moves downward under the action of the reset elastic member 120. After the first hook 221 is disengaged from the rotating member 30, the door body 220 is completely opened, the second end 712 of the torsion spring 51 is located on the side of the line 72 close to the door body 220, so that the torsion spring 51 applies an action force along the first direction to the rotating member 30, and the action force makes the rotating member 30 abut against the support 10, so that the rotating member 30 is kept in the static state.
