Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cooking electric appliances, and in particular to a door locking device and a cooking electric appliance. BACKGROUND

[0002] In the related art, a cooking electric appliance has a cavity and a door body, the door body is rotatably 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 electric appliance during operation, for example, to prevent the cooking electric appliance from starting to work when the door body has not been completely closed, a catch is generally arranged on the door body, and the catch is movably connected to the door body by a spring. A door locking mechanism is arranged on the cavity of the cooking electric appliance, and the door locking 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.

[0003] 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.

[0048] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For the purpose of simplification, the elements of the particular examples of the present application are described. Of course, they are merely examples and are not intended to limit the present application. The elements of the present application can be repeated with reference numerals and / or reference letters in different examples for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or arrangements discussed. In addition, the present application provides various specific examples of processes and materials, but those of ordinary skill in the art can realize the application of other processes and / or the use of other materials.

[0049] Referring to Figure 1 and Figure 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, the door body 220 is installed at the opening of the cavity 210, and 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 through a hinge. The door lock device 100 connects the cavity 210 and the door body 220, and is used to realize the opening and closing of the door body 220 relative to the cavity 210.

[0050] Referring to Figures 3-6 In some embodiments, the door lock device 100 includes a bracket 10, a clamping piece 20, a rotating piece 30, and a locking assembly 40. The bracket 10 is used to be installed on the cavity 210, the clamping piece 20 is used to be fixed on the door body 220, the door body 220 is rotationally connected with the cavity 210, the rotating piece 30 is installed on the bracket 10 and can rotate relative to the bracket 10, the rotating piece 30 is used to rotate between a first position and a second position, the rotating piece 30 can be clamped with the clamping piece 20 to drive the door body 220 to close during the process that the clamping piece 20 pushes the rotating piece 30 to rotate from the first position to the second position, and the locking assembly 40 is installed on the bracket 10. The locking assembly 40 is used to lock or unlock the rotating piece 30 when the rotating piece 30 is in the second position. When the rotating piece 30 is locked, the rotating piece 30 remains fixed relative to the bracket 10, and when the rotating piece 30 is unlocked, the rotating piece 30 can rotate relative to the bracket 10.

[0051] Therefore, 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] Please refer to Figures 4-7In some embodiments, the locking assembly 40 comprises a locking member 41 and a driving member 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 member 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.

[0059] In this way, the driving member 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, thereby 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 member 42 cooperate to make it easy to realize the function of the locking assembly 40 locking the rotating member 30.

[0060] In addition, the locking member 41 is rotatably arranged on the bracket 10, so that the driving member 42 can be arranged on one side of the locking member 41 in the circumferential direction. The driving member 42 can be flexibly arranged on the bracket 10 to make full use of the space of the bracket 10, thereby making the structure of the door lock device 100 more compact.

[0061] Specifically, please refer to Figure 6 and Figure 7 For example, the locking member 41 can be provided with a rotating hole 411, and the bracket 10 can be provided with a rotating shaft 11. The locking member 41 can be sleeved on the rotating shaft 11 through the rotating 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, thereby locking the rotating member 30.

[0062] 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, and the rotating member 30 can move relative to the bracket 10, thereby unlocking the rotating member 30.

[0063] The driving member 42 can include, but is not limited to, an electromagnetic component, a pneumatic component, an electro-deformation component, an elastic component, etc. The driving member 42 can be installed on the bracket 10 by means of screws or other fasteners.

[0064] In the embodiments of the present application, the unlocked position of the locking member 41 is, for example, the position shown in Figure 8 , and the locked position of the locking member 41 is, for example, the position shown in Figure 9 .

[0065] Please refer to Figures 7-9In some embodiments, the locking member 41 can rotate from the locked position to the unlocked position under the action of gravity when the driving member 42 ceases to drive 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. Thus, even if the cooking appliance 200 is powered off, the door body 220 can still be opened, and the convenience of using the cooking appliance 200 is improved.

[0066] Referring to Figures 5-7 In some embodiments, the driving member 42 and the rotating member 30 are arranged on opposite sides of the support 10, 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 structure compactness of the door lock device 100 is improved, and the door lock device 100 is more miniaturized.

[0067] Referring to Figures 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 locks the rotating member 30 when the abutting portion 413 abuts against the rotating member 30. The driving member 42 drives the locking member 41 to rotate through the pushing portion 414.

[0068] 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. The rotating portion 412 can be sleeved on the adapter shaft 11 of the support 10, so that the locking member 41 rotates relative to the support 10 through the rotating portion 412.

[0069] 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. 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.

[0070] 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 when the driving member 42 ceases to drive the locking member 41.

[0071] 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.

[0072] It can be understood that, since 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 an arc shape, in order to avoid the abutting portion 413, the guide hole 14 of the bracket 10 is also in an arc shape, so that the bracket 10 does not interfere with the movement of the abutting portion 413.

[0073] It should be noted that the abutting portion 413 abuts against the rotating member 30, which can mean 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 can mean 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.

[0074] Please refer to Figures 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 rotatably connected with the bracket 10, the connecting portion 35 is connected with the rotating portion 34, the blocking rib 36 is connected with the edge of the rotating portion 34, the blocking rib 36 and the connecting portion 35 enclose an activity space 37, and the blocking rib 36 is provided with a gap 361 communicating with the activity space 37;

[0075] When the rotating member 30 is in the second position, the abutting portion 413 extends into the activity space 37, and the abutting portion 413 abuts against the blocking rib 36 when the locking member 41 is in the locked position;

[0076] The abutting portion 413 is on the movement track of the gap 361 when the locking member 41 is in the unlocked position, and the gap 361 passes through the abutting portion 413 during the rotation of the rotating member 30 from the second position to the first position.

[0077] In this way, the abutting portion 413 and the blocking rib 36 cooperate to lock the rotating member 30, and the abutting portion 413 and the gap 361 cooperate to unlock the rotating member 30.

[0078] Specifically, the rotating portion 34 can be in a cylindrical shape and is installed on the bracket 10, the connecting portion 35 is in a fan-like structure, the connecting portion 35 is formed with a clamping groove 33, during the closing of the door body 220, 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.

[0079] The blocking rib 36 is in a strip shape and extends along the edge of the connecting portion 35, and the gap 361 is a vacant part on the blocking rib 36, which can pass the abutting portion 413 during the rotation of the rotating member 30, so that the abutting portion 413 is located in the activity space 37 of the rotating member 30 or outside the activity space 37.

[0080] Please refer to Figure 8 and Figure 9 In some embodiments, the driving component 42 comprises an electromagnetic portion 421 and a push rod 422, the push rod 422 is arranged in the electromagnetic portion 421, and 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.

[0081] In this way, the driving component 42 drives the push rod 422 to move by electromagnetic mode, so that the rotation of the locking member 41 is more easily controlled. For example, when 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.

[0082] Specifically, the push rod 422 can be made of a magnetic material, that is, the push rod 422 is a magnetic member. The magnetic member includes a material containing iron and other elements. The magnetic member can be a permanent magnet or a non-permanent magnet. After the electromagnetic portion 421 is powered, the electromagnetic portion 421 generates a magnetic force, so that the electromagnetic portion 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 abutting portion 414 during the movement, thereby making the locking member 41 rotate.

[0083] Please refer to Figure 3 , Figure 5 and Figure 7 In some embodiments, the door lock device 100 further comprises a damping member 110, the damping member 110 comprises a first buffering portion 111 and a second buffering portion 112 rotationally connected with the first buffering portion 111, the first buffering portion 111 is installed on the support 10, and the second buffering portion 112 at least partially extends into the rotating member 30. During the rotation of the rotating member 30, the first buffering portion 111 rotates relative to the second buffering portion 112, so as to slow down the rotation speed of the rotating member 30 through the damping between the first buffering portion 111 and the second buffering portion 112, thereby slowing down the closing speed of the door body 220.

[0084] The first buffering portion 111 and the second buffering portion 112 of the damping member 110 are two mutually rotating parts. A viscous liquid can be arranged in the first buffering portion 111 and / or the second buffering portion 112, which can provide resistance, so that the first buffering portion 111 and the second buffering portion 112 have damping during mutual rotation.

[0085] The first buffer part 111 can be fixed on the support 10 by interference fit, threaded connection, clamping connection, etc., and the second buffer part 112 can also be installed in the rotating part 30 by interference fit, threaded connection, clamping connection, etc.

[0086] The second buffer part 112 can be entirely inserted into the rotating part 30 or partially inserted into the rotating part 30.

[0087] In some embodiments, the damping part 110 can be a one-way damper, which can slow down the closing speed of the door body 220 during the closing process of the door body 220, and does not provide damping and does not hinder the opening of the door body 220 during the opening process of the door body 220, so as to reduce the collision between the door body 220 and the cavity 210 and reduce noise when the door body 220 is closed; the damping part 110 does not slow down the opening speed of the door body 220 when the door body 220 is opened, which is more labor-saving and improves user experience.

[0088] Referring to Figure 7 and Figure 10 In some embodiments, the rotating part 30 is provided with a mounting hole 31, one end of the second buffer part 112 is inserted into the mounting hole 31, and the second buffer part 112 cooperates with the hole wall of the mounting hole 31 to apply a buffer force to the rotating part 30. In this way, the mounting hole 31 can make the rotating part 30 and the second buffer part 112 have at least partially overlapping space, so that the second buffer part 112 cooperates with the rotating part 30 more compactly.

[0089] Specifically, the mounting hole 31 can be a non-circular hole, so that after the one end of the second buffer part 112 is inserted into the mounting hole 31, the second buffer part 112 does not rotate relative to the rotating part 30 along the circumference of the mounting hole 31, so that the second buffer part 112 moves synchronously with the rotating part 30.

[0090] Of course, the mounting hole 31 can also be a circular hole, at this time, the one end of the second buffer part 112 can be interference fit with the mounting hole 31, or limited from rotating relative to the mounting hole 31 by connecting keys, etc.

[0091] Referring to Figure 5 , Figure 7 and Figure 10 In some embodiments, the rotating part 30 is used to rotate between a first position and a second position, and the rotating part 30 drives the door body 220 to close by the clamping part 20 during the rotation from the first position to the second position.

[0092] The hole wall of the mounting hole 31 is formed with a stop portion 32, and when the rotating member 30 is in the first position, one end of the second buffer portion 112 is spaced apart from the stop portion 32, and after the rotating member 30 is rotated by a preset angle from the first position to the second position, one end of the first buffer portion 111 is matched with the stop portion 32, so that the damping member 110 slows down the rotating speed of the rotating member 30.

[0093] 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 can rotate relative to the first rotating member 30, at this time, the damping member 110 has no damping effect on the first rotating member 30, and after the rotating member 30 is rotated by a preset angle from the first position to the second position, one end of the second buffer portion 112 is in contact with the stop portion 32, so that the rotating member 30 and the second buffer portion 112 can be synchronously rotated relative to the support 10, at this time, the damping member 110 has a damping effect on the rotating member 30, which slows down the rotating speed of the rotating member 30, and further slows down the closing speed of the door body 220.

[0094] 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, and 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 are synchronously rotated.

[0095] In some embodiments, the above-mentioned preset angle can be 5-10°, for example, the preset angle can be 5°, 8°, 10°, etc., that is to say, after the rotating member 30 is rotated by a 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.

[0096] Please refer to Figure 7 In some embodiments, the support 10 is provided with a mounting hole 13, and the first buffer portion 111 is at least partially arranged in the mounting 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.

[0097] Please refer to Figure 3 , Figure 5 and Figure 7 In some embodiments, the door lock device 100 comprises a first elastic member 50, the first elastic member 50 is connected to the support 10 and the rotating member 30, and the first elastic member 50 can apply an elastic force to the rotating member 30 when the rotating member 30 is matched with the clamping member 20, so that the rotating member 30 is rotated to drive the door body 220 to close through the clamping member 20.

[0098] In this way, the first elastic member 50 can enable the door body 220 to be automatically closed 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 30 is controllable, so that the collision between the door body 220 and the cavity 210 during 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 by pushing, pulling or other medium.

[0099] Please refer to Figure 3 、 Figure 5 and Figure 7 In some embodiments, the first elastic member 50 includes a torsion spring 51, a first end 511 of the torsion spring 51 is connected to the support 10, and a second end 512 of the torsion spring 51 is connected to the rotating member 30.

[0100] 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.

[0101] 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, and the first side and the second side are located on opposite sides of the line 101.

[0102] In this way, the torsion spring 51 stores energy during the opening process of the door body 220, and keeps the rotating member 30 in a tendency of rotating in a first direction after the door body 220 is opened, so as to keep the rotating member 30 in the first position. The torsion spring 51 can release the stored energy and make the rotating member 30 rotate in a second direction during the closing process of the door body 220, so as to drive the door body 220 to be closed by the clamping member 20, and the first direction is opposite to the second direction. The first direction is a direction from the second position to the first position.

[0103] The rotating member 30 is driven to rotate by the torsion spring 51, so that the structure of the first elastic member 50 is simple and easy to implement, and the cost of the torsion spring 51 is relatively low, which can reduce the cost of the first elastic member 50.

[0104] Specifically, when the rotating member 30 is kept in the first position, the support 10 provides support for the rotating member 30, thereby limiting the rotating member 30 to continue to rotate in the first direction. For example, when the rotating member 30 is in the first position, the rotating member 30 can abut against the support 10.

[0105] As Figure 11As shown, during the opening of the door 220, the retaining member 20 engages with the rotating member 30, and the retaining member 20 can drive the rotating member 30 to rotate. At this time, the torsion spring 51 stores force. After the door 220 opens and the retaining member 20 disengages from the rotating member 30, the second end 512 of the torsion spring 51 is located on the side of the connecting line 101 closer to the door 220, so that the torsion spring 51 applies a force to the rotating member 30 to rotate in the first direction. This force causes the rotating member 30 to act with the bracket 10 so that the rotating member 30 remains stationary.

[0106] like Figure 12 and Figure 13 As shown, during the closing process of the door 220, the user first pushes the door 220 (or the handle on the door 220). As the user continues to push the door 220, or due to the inertia generated after the user pushes the door 220, the door 220 drives the retaining member 20 to move in the closing direction. The retaining member 20 extends into the bracket 10 and engages with the rotating member 30. As the retaining member 20 moves, it drives the rotating member 30 to rotate. After the rotating member 30 rotates through a predetermined angle in the second direction, the second end 512 of the torsion spring 51 is located on the side of the connecting line 101 away from the door 220. The torsion spring 51 releases its stored force and causes the rotating member 30 to rotate in the second direction, thereby causing the rotating member 30 to pull the retaining member 20 and drive the door 220 to rotate until it is completely closed.

[0107] It can be understood that the first direction of rotation of the rotating component 30 is the direction in which the rotating component 30 rotates during the process of the door 220 switching from the closed state to the open state, for example... Figure 7 The direction shown is counterclockwise. It should be noted that in other embodiments, the first elastic element 50 can be a tension spring, an electromagnetic drive component, or other similar components.

[0108] Please see Figure 7 and Figure 11 In some embodiments, the door lock device 100 further includes a second elastic member 60 disposed on the bracket 10, which applies an elastic force to the rotating member 30 toward the second position when the rotating member 30 is in the first position.

[0109] Thus, the elastic force applied by the second elastic element 60 to the rotating element 30 is opposite in direction to the force or component force applied by the torsion spring 51 to the rotating element 30. During the closing process of the door 220, only a small pushing force needs to be provided to the door 220. With the assistance of the second elastic element 60, the holding element 20 can make it easier for the rotating element 30 to overcome the resistance of the torsion spring 51, thereby making it easier for the door 220 to close and improving the user experience.

[0110] Specifically, the second elastic member 60 includes, but is not limited to, a coil spring, an elastic block, etc., and the shape of the second elastic member 60 is, for example, substantially a circular truncated cone. The second elastic member 60 can be fixed on the support 10 by means of clamping.

[0111] It should be noted that, in the case that the rotating member 30 is in the first position, the force exerted on the rotating member 30 by the first elastic member 50 can be greater than the force exerted on the rotating member 30 by the second elastic member 60, so that the rotating member 30 can be kept in the first position.

[0112] Please refer to Figure 7 and Figure 11 In some embodiments, the clamping member 20 includes a mounting portion 21, a first clamping portion 22 and a second clamping portion 23, the mounting portion 21 is used for being fixed 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 clamping hook 221, the rotating member 30 is formed with a clamping groove 33, and the rotating member 30 can be driven by the first clamping portion 22 to close the door body in the case that the clamping hook 221 and the clamping groove 33 are clamped.

[0113] In this way, the clamping hook 221 of the first clamping portion 22 and the clamping groove 33 are clamped, so that the rotating member 30 avoids being separated from the clamping member 20 during rotation, thereby improving the stability of the rotating member 30 in driving the door body 220 to close by the first clamping portion 22.

[0114] It should be noted that the clamping point of the clamping hook 221 and the clamping groove 33 can change with the rotation of the rotating member 30, and in the process of closing the door body 220, the clamping hook 221 and the clamping groove 33 remain clamped as the clamping point changes; in the process of opening the door body 220, the clamping hook 221 and the clamping groove 33 can be separated as the clamping point changes so that the door body 220 can be completely opened.

[0115] Please refer to Figure 7 and Figure 11 In some embodiments, the door lock device 100 further includes a stop member 70 rotatably arranged on the support 10, and the second clamping portion 23 clamps the stop member 70 in the case that the door body 220 is closed.

[0116] In this way, the second clamping portion 23 clamps the stop member 70 in the case that the door body 220 is closed, which can improve the stability of the door body 220 in closing and reduce the risk of the cooking appliance 200 being abnormally opened during normal operation.

[0117] Specifically, as Figure 7As shown, the stopper 70 can be provided with a connecting hole 71, and the support 10 can be provided with a pivoting shaft 12, the stopper 70 can be sleeved on the pivoting shaft 12 through the connecting hole 71, so as to be pivotally connected with the support 10. The second clamping part 23 is similar to a sheet, and the second clamping part 23 can be formed with a clamping hole 231, and the stopper 70 can be provided with a clamping block 72, the clamping hole 231 can be matched with the clamping block 72, so that the second clamping part 23 is clamped with the stopper 70.

[0118] In the embodiments of the present application, the mounting part 21, the first clamping part 22 and the second clamping part 23 are integrated structures, for example, the mounting part 21, the first clamping part 22 and the second clamping part 23 can be formed by pressure casting or the like. Of course, the mounting part 21, the first clamping part 22 and the second clamping part 23 are separate structures, and the first clamping part 22 and the second clamping part 23 can be fixed on the mounting part 21 by screws or the like.

[0119] Please refer to Figure 7 and Figure 11 In some embodiments, the door lock device 100 further comprises a third elastic member 80, the third elastic member 80 connects the stopper 70 and the support 10, and the third elastic member 80 is used to apply a reset elastic force to the stopper 70 when the second clamping part 23 is separated from the stopper 70.

[0120] In this way, the third elastic member 80 makes the stopper 70 reset after rotation, 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 more labor-saving when opening, and the user experience is improved.

[0121] 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 support 10, and the other end can be clamped into the stopper 70.

[0122] Please refer to Figure 3 , Figure 5 and Figure 7 In some embodiments, the door lock device 100 can further comprise a micro switch 90 provided on the support 10, and when the micro switch 90 is triggered, it can be confirmed that the door body 220 is in a closed state.

[0123] Please refer to Figures 1-3In some embodiments, the cooking appliance 200 further comprises a control box 230 and an on-off 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 on-off key 240 is arranged on the control box 230. The on-off key 240 can be a touch key or a mechanical key. The on-off key 240 is used 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 make the locking assembly 40 lock or unlock the rotating piece 30.

[0124] In summary, in one embodiment of the present application, the door closing process of the cooking appliance 200 is as follows:

[0125] Please refer to Figure 7 , Figure 8 , Figures 11-14 , 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 piece 30 to rotate, the second clamping part 23 pushes the stopper 70 to rotate, after the rotating piece 30 rotates through a predetermined angle in the second direction, the damping part 110 cooperates with the rotating piece 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 piece 30 to rotate in the second direction, so that the rotating piece 30 pulls the first clamping part 22 to drive the door body 220 to continue closing, and the damping part 110 can slow down the closing speed of the door body 220.

[0126] 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, and 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 piece 30, reduces the risk that the door body 220 is directly opened by pulling, and ensures the door opening safety of the cooking appliance 200.

[0127] It can be understood that the door opening process of the cooking appliance 200 is opposite to the door closing process, and is as follows:

[0128] Please refer to Figure 7 , Figures 8-10 , Figures 11-14When the cooking appliance 200 is completed, if the key 240 is not pressed, the electromagnet 421 can keep energized for a preset time (for example, 30 minutes), and in this process, the locking member 41 keeps the rotating member 30 locked. If the key 240 is pressed, the key 240 sends a command to the control box 230, and the control box 230 de-energizes the electromagnet 421 after receiving the unlocking command. At this time, the electromagnet 421 has no force on the push rod 422. The locking member 41 rotates under the action of its own weight and the gravity of the push rod 422 to move from the locked position to the unlocked position, so that the rotating member 30 is unlocked.

[0129] After the rotating member 30 is unlocked, the door body 220 is pulled, the first clamping part 22 drives the rotating member 30 to rotate, and the second clamping part 23 drives the stopper 70 to rotate. In this process, the torsional spring 51 stores energy. After the first clamping part 22 and the rotating member 30 are disengaged, and the second clamping part 23 and the stopper 70 are disengaged, the door body 220 is completely opened, and the second end 512 of the torsional spring 51 is located on the side of the line 101 close to the door body 220, so that the torsional spring 51 applies a force to the rotating member 30 in the first direction. The force makes the rotating member 30 remain in the first position.
