[0002] In the related art, a microwave oven usually only has a slow closing function and does not have a child lock. It is easy for children to open the microwave oven door and accidentally touch the heated food or beverage and get scalded. Content of the Utility Model

[0003] The utility model aims to at least solve or improve the technical problem that a microwave oven with a slow closing function in the prior art does not have a child lock.

[0004] For this reason, some embodiments of the utility model propose a cooking appliance.

[0005] In view of this, according to some embodiments of the utility model, the utility model proposes a cooking appliance, including: a main body; a door body hinged to the main body; a first locking hook movably arranged on the door body; a second locking hook arranged on the door body; a reset member arranged on the door body and connected to the first locking hook; a fixing frame arranged on the main body; a slow closing door structure arranged on the fixing frame, and the slow closing door structure is used to cooperate with the second locking hook; a locking piece arranged on the fixing frame, the locking piece includes a guiding surface, and the locking piece is used to cooperate with the first locking hook, and the guiding surface is used to guide the first locking hook during the closing process of the cooking appliance; wherein, when the main body and the door body are in a closed state and the first locking hook is in a first position, the locking piece and the first locking hook are in a locking cooperation, when the main body and the door body are in a closed state and the first locking hook is in a second position, the locking piece and the first locking hook are in an unlocking cooperation, and the reset member is used to move the first locking hook to the first position; the opening direction of the door body is a first direction, the direction from the first position to the second position is a second direction, and the first direction and the second direction are different.

[0006] The cooking appliance proposed by the utility model includes a main body and a door body, and the main body and the door body are hinged so that the main body and the door body can be opened and closed. Specifically, there are a closed state and an open state between the main body and the door body.

[0007] The cooking appliance further includes a first locking hook, a second locking hook and a reset member. The first locking hook, the second locking hook and the reset member are arranged on the door body, the reset member is connected to the first locking hook, and the first locking hook is movably arranged on the door body. The cooking appliance further includes a locking piece arranged on the main body, and the locking piece has a guiding surface. Further, during the closing process of the door body and the main body, the first locking hook will contact the guiding surface, and under the action of the guiding surface, the first locking hook will move. Thus, after the head of the first locking hook crosses the locking piece, locking is achieved. At this time, the locking piece blocks and locks the first locking hook to achieve the child lock function.

[0008] Specifically, when the main body and the door body are in the closed state and the first locking hook is in the first position, the locking piece and the first locking hook are in a locked engagement. When the main body and the door body are in the closed state and the first locking hook is in the second position, the locking piece and the first locking hook are in an unlocking engagement. The reset member is used to move the first locking hook to the first position. The opening direction of the door body is the first direction, and the direction from the first position to the second position is the second direction. The first direction and the second direction are different, so as to realize the child lock function by using different opening directions. Herein, the second position and the first position are relative to the door body.

[0009] The cooking appliance further includes a fixing bracket and a slow-closing door structure. The fixing bracket is arranged on the main body, and the slow-closing door structure is arranged on the fixing bracket. The second locking hook can realize the slow-closing function of the door through the slow-closing door structure.

[0010] Specifically, when closing the door body, the second locking hook contacts the slow-closing door structure, and the slow-closing door structure drives the second locking hook, the door body and the first locking hook to close the door slowly. After that, the guiding surface of the first locking hook and the locking piece come into contact. The guiding surface provides guidance for the first locking hook, so that the first locking piece moves from the second position to the first position. After the head of the first locking hook passes over the locking piece, the reset member drives the first locking hook to move to the first position, so that the first locking hook and the locking piece are in a locked engagement, and the slow-closing door structure makes the door body and the main body complete the closing, so that the main body and the door body are in the closed state.

[0011] When opening the door body, first move the first locking hook to make the first locking hook move from the first position to the second position, so that the first locking hook and the locking piece are in an unlocking engagement. Then pull the door body in the second direction to make the second locking hook disengage from the slow-closing door structure. During this process, the first locking hook can pass over the locking piece to realize the open state of the door body and the main body.

[0012] As above, the cooking appliance provided by the present utility model realizes the child lock function through the first locking hook and the slow-closing function through the second locking hook, thereby improving the safety of the cooking appliance.

[0013] In addition, according to the cooking appliance in the above technical solution provided by the present utility model, the following additional technical features may also be included:

[0014] In some embodiments, optionally, the guiding surface is a curved surface. When the main body and the door body are in the closed state, the guiding surface protrudes towards the door body.

[0015] In this embodiment, the guiding surface is a curved surface, and when the main body and the door body are in the closed state, the guiding surface protrudes towards the door body, thereby improving the guiding effect of the guiding surface on the first locking hook, and reducing the possibility of the first locking buckle being stuck with the guiding surface, making the movement of the first locking hook smoother.

[0016] In some embodiments, optionally, the slow-closing door structure includes: a driving lever rotatably disposed on a fixed bracket, the driving lever including a second hook for cooperating with a second locking hook; a driving assembly disposed on the fixed bracket and connected to the driving lever; wherein, when the driving lever is in a balanced state, the second hook and the second locking hook are in an unlocking fit, and when the second locking hook drives the driving lever out of the balanced state, the driving assembly drives the driving lever to rotate and makes the second hook and the second locking hook in a locked state.

[0017] In this embodiment, the slow-closing door structure includes a driving lever and a driving assembly. The driving lever includes a second hook that can cooperate with a second locking hook. The driving lever is rotatably disposed on a fixed bracket, and the driving assembly is also disposed on the fixed bracket. The driving assembly can drive the driving lever to rotate. Specifically, when the driving assembly is in a balanced state, the driving assembly cannot drive the driving lever to move. During the process of closing the door, the second locking hook drives the driving lever to move, causing the driving lever to deviate from the balanced state. As a result, after the driving lever deviates from the balanced state, the driving assembly drives the driving lever to move, and the second hook can hook the second locking hook, thereby enabling the driving lever to drive the second locking hook to move and realizing the automatic slow closing of the door body.

[0018] This structure triggers the closing operation of the slow-closing door structure through the second locking hook on the door body, improving the reliability of closing the cooking appliance door.

[0019] In some embodiments, optionally, the slow-closing door structure further includes: a damper disposed on the fixed bracket and connected to the driving lever.

[0020] In this embodiment, the slow-closing door structure further includes a damper disposed on the fixed bracket, and the damper is connected to the driving lever, thereby reducing the speed at which the driving lever drives the second locking hook to move and enhancing the effect of slow closing the door.

One end of the first elastic member is connected to the fixing bracket, and the other end is connected to the first position of the driving lever. One end of the second elastic member is connected to the fixing bracket, and the other end is connected to the second position of the driving lever. Thus, the first elastic member and the second elastic member apply forces in different directions. When the driving lever is in the balanced position, the driving lever itself is in force balance. Among them, the driving lever can abut against the fixing bracket to achieve the balanced state. When the second locking hook causes the driving lever to deviate from the balanced state, at this time, the first elastic member and the second elastic member drive the driving lever to rotate, so that the driving lever drives the second locking hook to move, achieving the effect of slow closing of the door.

[0025] Moreover, the structures of the first elastic member and the second elastic member are simple, and the driving effect is reliable.

[0026] In some embodiments, optionally, it further includes: a microwave generating circuit, which includes a microwave generator and a first switch; a power supply circuit, electrically connected to the microwave generating circuit, and the power supply circuit is used to supply power to the microwave generating circuit, and the power supply circuit includes a second switch; a short-circuiting circuit, connected to the microwave generating circuit, and the short-circuiting circuit is used to short-circuit the microwave generator, and the short-circuiting circuit includes a third switch; wherein, when the main body and the door body are in the closed state, the first switch is in the conducting state, the second switch is in the conducting state, and the third switch is in the open state; when the main body and the door body are in the open state, the first switch is in the open state, the second switch is in the conducting state, and the third switch is in the conducting state.

[0027] In this embodiment, the cooking appliance further includes a microwave generating circuit, a power supply circuit, and a short-circuiting circuit. The microwave generating circuit, the power supply circuit, and the short-circuiting circuit are all arranged in the main body. The power supply circuit is used to supply power to the microwave generating circuit. The microwave generating circuit includes a microwave generator, and the microwave generator is used to generate microwaves to achieve heating of items.

[0032] In some embodiments, optionally, further included is a rotating lever rotatably disposed on the fixing bracket. When the main body and the door body are in a closed state, the second locking hook triggers the first switch through the rotating lever.

[0033] In this embodiment, the cooking appliance further includes a rotating lever rotatably disposed on the fixing bracket. When the main body and the door body are in a closed state, the second locking hook triggers the first switch through the rotating lever. That is, the first switch is triggered through the rotating lever, increasing the insurance of the first switch triggering and reducing the possibility of other tools being inserted into the fixing bracket to trigger the first switch, further enhancing the safety of the cooking appliance.

[0034] In some embodiments, optionally, the fixing bracket includes: a plate body, on which the slow-closing door structure is disposed; an end cap disposed on the plate body, and the third switch is disposed on a side of the end cap away from the plate body.

[0035] In this embodiment, the fixing bracket includes a plate body and an end cap.

Detailed implementation manners

[0059] In order to be able to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0060] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present utility model is not limited by the specific embodiments disclosed below.

[0061] The following refers to Figures 1 to 19 to describe the cooking appliance 100 provided according to some embodiments of the present utility model.

[0062] As Figure 1 and Figure 2 shown, according to some embodiments of the present utility model, the present utility model provides a cooking appliance 100. The cooking appliance 100 includes a main body 110 and a door body 120. The main body 110 and the door body 120 are hinged. The main body 110 has a cooking cavity. The main body 110 and the door body 120 have a closed state and an open state. When the main body 110 and the door body 120 are in the closed state, the door body 120 closes the cooking cavity. When the main body 110 and the door body 120 are in the open state, the cooking cavity is open.

[0063] The cooking appliance 100 further includes a first locking hook 130, a second locking hook 140, and a reset member 150. The first locking hook 130, the second locking hook 140, and the reset member 150 are all disposed on the door body 120. The first locking hook 130 is movable relative to the door body 120. The second locking hook 140 is fixed to the door body 120. The reset member 150 is connected to the first locking hook 130. When there is no external force acting on the first locking hook 130, the reset member 150 positions the first locking hook 130 at the first position 242. When the first locking hook 130 is at the first position 242 and the main body 110 and the door body 120 are in the closed state, the locking piece 190 and the first locking hook 130 are in a locking engagement, and at this time, the door body 120 cannot be opened.

[0064] The first locking hook 130 can be moved to the second position 244 by an external force. When the first locking hook 130 is at the second position 244 and the main body 110 and the door body 120 are in the closed state, the locking piece 190 and the first locking hook 130 are in an unlocking engagement, and at this time, the door body 120 can be opened.

[0065] Moreover, during the closing process of the door body 120, the first locking hook 130 contacts the guiding surface 192 of the locking piece 190, and under the guidance of the guiding surface 192, the first locking hook 130 gradually moves to the second position 244, thus passing over the locking piece 190. After the door body 120 is completely closed, the unlocking engagement between the locking piece 190 and the first locking hook 130 is achieved.

[0066] As Figure 3 、 Figure 4 、 Figure 5 、 Figure 12 、 Figure 14 and Figure 16 shown, the opening direction of the door body 120 is the first direction ba. As Figure 12 、 Figure 13 、 Figure 14 、 Figure 16 shown, the direction from the first position 242 to the second position 244 is the second direction dc. The first direction ba and the second direction dc are different. Specifically, the first direction ba and the second direction dc can be perpendicular to each other.

[0067] The cooking appliance 100 provided by the present utility model includes a main body 110 and a door body 120. The main body 110 and the door body 120 are hinged so that the main body 110 and the door body 120 can be opened and closed. Specifically, there are a closed state and an open state between the main body 110 and the door body 120.

[0068] The cooking appliance 100 further includes a first locking hook 130, a second locking hook 140, and a reset member 150. The first locking hook 130, the second locking hook 140, and the reset member 150 are provided on the door body 120. The reset member 150 is connected to the first locking hook 130. The first locking hook 130 is movably provided on the door body 120. The cooking appliance 100 further includes a locking piece 190. The locking piece 190 is provided on the main body 110. And the locking piece 190 has a guiding surface 192. Further, during the closing process of the door body 120 and the main body 110, the first locking hook 130 will contact the guiding surface 192. And under the action of the guiding surface 192, the first locking hook 130 will move. Thus, after the head of the first locking hook 130 crosses over the locking piece 190, locking is achieved. At this time, the locking piece 190 blocks and locks the first locking hook 130, realizing the child lock function.

[0069] Specifically, when the main body 110 and the door body 120 are in the closed state and the first locking hook 130 is in the first position 242, the locking piece 190 and the first locking hook 130 are in locking cooperation. When the main body 110 and the door body 120 are in the closed state and the first locking hook 130 is in the second position 244, the locking piece 190 and the first locking hook 130 are in unlocking cooperation. The reset member 150 is used to move the first locking hook 130 to the first position 242. The opening direction of the door body 120 is the first direction. The direction from the first position 242 to the second position 244 is the second direction. The first direction and the second direction are different. Thus, the child lock function is realized by the different opening directions. Wherein, the second position 244 and the first position 242 are relative to the door body 120. As Figure 9 、 Figure 13 and Figure 14 shown, at position f, the locking piece 190 abuts against the first locking hook 130, and at position g, the first locking hook 130 triggers the second switch 212.

[0070] The cooking appliance 100 further includes a fixing bracket 160 and a slow-closing door structure 170. The fixing bracket 160 is provided on the main body 110. The slow-closing door structure 170 is provided on the fixing bracket 160. The second locking hook 140 can realize the slow-closing door function through the slow-closing door structure 170.

[0071] Specifically, when closing the door body 120, the second locking hook 140 contacts the slow-closing door structure 170. The slow-closing door structure 170 drives the second locking hook 140, the door body 120, and the first locking hook 130 to slowly close the door. After that, the guiding surface 192 of the first locking hook 130 and the locking piece 190 come into contact. The guiding surface 192 provides guidance for the first locking hook 130, causing the first locking piece 190 to move from the second position 244 to the first position 242. After the head of the first locking hook 130 passes over the locking piece 190, the reset member 150 drives the first locking hook 130 to move to the first position 242, so that the first locking hook 130 and the locking piece 190 are in a locked cooperation. The slow-closing door structure 170 closes the door body 120 and the main body 110, making the main body 110 and the door body 120 in a closed state.

[0072] When opening the door body 120, first move the first locking hook 130 to make the first locking hook 130 move from the first position 242 to the second position 244, so that the first locking hook 130 and the locking piece 190 are in an unlocking cooperation. Then, pull the door body 120 in the second direction, causing the second locking hook 140 to disengage from the slow-closing door structure 170. During this process, the first locking hook 130 can pass over the locking piece 190, realizing the open state of the door body 120 and the main body 110.

[0073] As described above, the cooking appliance 100 provided by the present utility model realizes the child lock function through the first locking hook 130 and the slow-closing door function through the second locking hook 140, thereby improving the safety of the cooking appliance 100.

[0074] The cooking appliance 100 can adopt a side-opening mode. When the door body 120 is closed and the angle between the door body 120 and the main body 110 is within a range less than or equal to about 15 degrees, under the action of a relatively small door-pushing force, the door body 120 can automatically bring the second locking hook 140 into the slow-closing door structure, forming an effect of automatically absorbing and closing the door at a small angle. Among them, the door-pushing force can be less than or equal to 4N.

[0075] The cooking appliance 100 includes a second locking hook 140 fixed on the door body 120 and a first locking hook 130 that can slide up and down. A fixing bracket 160, a locking piece 190, and a slow-closing door structure are provided on the main body 110 and on the fixing bracket 160.

[0076] Among them, the reset member 150 can be a compression spring.

[0077] The cooking appliance 100 provided by the present utility model realizes a child lock with a simple structure. That is, it takes two steps to open the door body 120, and the structure is simple and reliable. It is easy for adults to open the door, and regardless of whether it is the left hand or the right hand, it is possible to open the door with one hand in two steps, and the door opening process is smooth and unobstructed. Moreover, the modification to the original door body 120 is small and the cost is low. When the cooking appliance 100 is closed, it is possible to close the door slowly, and moreover, the reliability of closing the cooking appliance 100 is improved. There is a gap between the door body 120 and the main body 110. When the cooking appliance 100 is opened, two steps are required, thereby improving the safety of the cooking appliance 100.

[0078] As Figure 7 , Figure 8 , Figure 10 , Figure 12 , Figure 15 and Figure 16 As shown in

[0079] In this embodiment, the guiding surface 192 is a curved surface, and the guiding surface 192 is curved along the direction in which the first locking hook 130 can move. When the main body 110 and the door body 120 are in a closed state, the guiding surface 192 protrudes towards the door body 120.

[0080] Specifically, the central angle of the guiding surface 192 can be from 0 to 180 degrees, and the central angle of the guiding surface 192 can be 90 degrees.

[0081] As Figure 4 , Figure 6 , Figure 8 and Figure 10 As shown in

[0082] Among them, the driving lever 172 can rotate to a balanced state. Specifically, in the balanced state, the driving lever 172 abuts against the fixed bracket 160. The driving assembly 180 provides a force for the driving lever 172 in the direction of abutting against the fixed bracket 160. Due to the limitation of the fixed bracket 160, the driving lever 172 is in a static state. After the second hook 140 drives the driving lever 172 to move in a direction away from the direction where the driving lever 172 abuts against the fixed bracket 160, the balance of the driving lever 172 is destroyed, so that the driving assembly 180 moves the driving lever 172 in a direction away from the direction where the driving lever 172 abuts against the fixed bracket 160. At this time, the second hook 174 on the driving lever 172 hooks the second hook 140, so that the second hook 174 and the second hook 140 are in a locked state, thereby driving the door body 120 to move.

[0083] In this embodiment, the slow-closing door structure 170 includes a driving lever 172 and a driving assembly 180. The driving lever 172 includes a second hook 174. The second hook 174 can cooperate with the second hook 140. The driving lever 172 is rotatably arranged on the fixed bracket 160. The driving assembly 180 is also arranged on the fixed bracket 160. The driving assembly 180 can drive the driving lever 172 to rotate. Specifically, when the driving assembly 180 is in a balanced state, the driving assembly 180 cannot drive the driving lever 172 to move. During the process of closing the door, the second hook 140 drives the driving lever 172 to move, so that the driving lever 172 is out of the balanced state. Therefore, after the driving lever 172 is out of the balanced state, the driving assembly 180 drives the driving lever 172 to move, and the second hook 174 can hook the second hook 140, thereby realizing that the driving lever 172 drives the second hook 140 to move and realizing the automatic slow closing of the door body 120.

[0084] This structure triggers the closing operation of the slow-closing door structure 170 through the second hook 140 on the door body 120, improving the reliability of closing the cooking appliance 100.

[0085] Such as Figure 4 、 Figure 6 、 Figure 8 and Figure 10 As shown, in some embodiments, optionally, the slow-closing door structure 170 further includes a damper 186 arranged on the fixed bracket 160, and the damper 186 is connected to the driving lever 172.

[0086] In this embodiment, the slow-closing door structure 170 further includes a damper 186 arranged on the fixed bracket 160, and the damper 186 is connected to the driving lever 172, thereby reducing the speed of the driving lever 172 driving the second hook 140 to move and improving the effect of slow closing the door.

[0087] Specifically, the driving lever 172 includes a lever body 176, a second hook 174, and a pendulum block 178. The pendulum block 178 is movably arranged on the lever body 176. The second hook 174 is arranged on the main body 110. The damper 186 and the pendulum block 178 are rotatably connected. Among them, the driving lever 172 has a slot, and the pendulum block 178 is arranged in the slot and can swing in the slot, thereby improving the flexibility of the damper 186 and the driving lever 172, enabling the driving lever 172 and the damper 186 to rotate flexibly.

[0088] As Figure 6 , Figure 8 , Figure 10 , Figure 15 and Figure 16 shown, in some embodiments, optionally, the fixing frame 160 includes a movable cavity 162. The damper 186 is rotatably arranged in the movable cavity 162, and the damper 186 and the driving lever 172 are rotatably connected.

[0089] In this embodiment, the fixing frame 160 has a movable cavity 162. The damper 186 is rotatably arranged in the movable cavity 162, and the damper 186 and the driving lever 172 are rotatably connected. Furthermore, the damper 186 can adjust its position and attitude during the rotation of the driving lever 172 to ensure the smooth rotation of the driving lever 172.

[0090] As Figure 5 and Figure 11 shown, in some embodiments, optionally, the driving assembly 180 includes a first elastic member 182 and a second elastic member 184. One end of the first elastic member 182 is connected to the fixing frame 160, and the other end is connected to the first position 242 of the driving lever 172. One end of the second elastic member 184 is connected to the fixing frame 160, and the other end is connected to the second position 244 of the driving lever 172; wherein, the first position 242 and the second position 244 can be located on both sides of the rotation center of the driving lever 172.

[0091] Among them, when the driving lever 172 abuts against the fixing frame 160, one of the first elastic member 182 and the second elastic member 184 has a greater elasticity, which can press the driving lever 172 against the fixing frame 160, making the driving lever 172 in a balanced state. After the second locking hook 140 drives the driving lever 172 to move out of the balanced state, the other of the first elastic member 182 and the second elastic member 184 has a greater elasticity, which can make the driving lever 172 rotate in the other direction, and at the same time, the second hook 174 drives the second locking hook 140 to move.

[0092] In this embodiment, the driving assembly 180 includes a first elastic member 182 and a second elastic member 184. One end of the first elastic member 182 is connected to the fixing bracket 160, and the other end is connected to the first position 242 of the driving lever 172. One end of the second elastic member 184 is connected to the fixing bracket 160, and the other end is connected to the second position 244 of the driving lever 172. The first position 242 and the second position 244 are respectively located on both sides of the rotation center of the driving lever 172. Thus, the first elastic member 182 and the second elastic member 184 apply forces in different directions. When the driving lever 172 is in the balanced position, the driving lever 172 itself is in force balance. Among them, the driving lever 172 can abut against the fixing bracket 160 to achieve the balanced state. When the second locking hook 140 causes the driving lever 172 to deviate from the balanced state, at this time, the first elastic member 182 and the second elastic member 184 drive the driving lever 172 to rotate, so that the driving lever 172 drives the second locking hook 140 to move, realizing the effect of slow closing of the door.

[0093] Moreover, the structures of the first elastic member 182 and the second elastic member 184 are simple, and the driving effect is reliable.

[0094] The slow-closing door structure is installed at the lower part of the fixing bracket 160. The slow-closing door structure includes a driving assembly 180, a driving lever 172, and a damper 186. The driving lever 172 is arranged on the front surface of the fixing bracket 160, the driving assembly 180 is arranged on the back surface of the fixing bracket 160, the fixing bracket 160 has a through hole, and the driving assembly 180 and the driving lever 172 are connected through the through hole.

[0095] The driving assembly 180 includes a first elastic member 182 and a second elastic member 184. The first elastic member 182 and the second elastic member 184 provide an inward closing pulling force during the door closing process. The damper 186 plays a role of buffering or soft closing during the door closing process. The driving lever 172 is pulled by the first elastic member 182 and the second elastic member 184, and drives the second locking hook 140 to move towards the direction of the main body 110 during the door closing process.

[0096] The driving lever 172 includes a lever main body 176 and a pendulum block 178. The pendulum block 178 is movably installed on the lever main body 176. The pendulum block 178 is rotatably connected to the damper 186, so that the pendulum block 178 can swing at a small angle, and can drive the damper 186 to rotate along with the driving lever 172. Moreover, since the pendulum block 178 can swing at a certain angle, the damper 186 can appropriately adjust its posture as the driving lever 172 rotates, making the rotation of the driving lever 172 smoother. Before the second locking hook 140 closes the door in place, it can push the rotating lever 230, thereby triggering the first switch 204 and making the first switch 204 in the conducting state.

[0097] Moreover, the drive lever 172 and the damper 186 are disposed on the plate body 164, and the end cap 166 is disposed on the plate body 164 to protect the drive lever 172 and the damper 186 therein, so as to ensure that the drive lever 172 and the damper 186 can move within the internal space of the plate body 164 and the end cap 166, reducing the occurrence of the drive lever 172 and the damper 186 detaching. The first switch 204 is disposed on the side of the end cap 166 facing away from the plate body 164. When the drive lever 172 rotates, the boss of the drive body 110 facing away from the end cap 166 can trigger the third switch 222 or restore the third switch 222 to the closed state.

[0098] A locking piece 190 is disposed on the upper part of the fixing bracket 160. After the first locking hook 130 crosses the guiding surface 192 of the locking piece 190, the second switch 212 can be triggered to make the second switch 212 in the conducting state. When the first locking hook 130 leaves the position hook, the second circuit is in the open state.

[0099] As Figure 19 shown, in some embodiments, optionally, the cooking appliance 100 further includes a microwave generation circuit 200, a power supply circuit 210, and a short - circuiting circuit 220. The microwave generation circuit 200 includes a microwave generator 202 and a first switch 204. The second switch 212 can adjust the on - off of the microwave generation circuit 200. The power supply circuit 210 is electrically connected to the microwave generation circuit 200, and the power supply circuit 210 is used to supply power to the microwave generation circuit 200. The power supply circuit 210 includes the second switch 212, and the second switch 212 can adjust the on - off of the power supply circuit 210. The short - circuiting circuit 220 is connected to the microwave generation circuit 200, and the short - circuiting circuit 220 is used to short - circuit the microwave generator 202. The short - circuiting circuit 220 includes a third switch 222, and the third switch 222 is used to adjust the on - off of the short - circuiting circuit 220. Among them, when the main body 110 and the door body 120 are in the closed state, the first switch 204 is in the conducting state, the second switch 212 is in the conducting state, and the third switch 222 is in the open state; when the main body 110 and the door body 120 are in the open state, the first switch 204 is in the open state, the second switch is in the conducting state, and the third switch 222 is in the conducting state.

[0100] In this embodiment, the cooking appliance 100 further includes a microwave generation circuit 200, a power supply circuit 210, and a short - circuiting circuit 220. The microwave generation circuit 200, the power supply circuit 210, and the short - circuiting circuit 220 are all disposed in the main body 110. The power supply circuit 210 is used to supply power to the microwave generation circuit 200. The microwave generation circuit 200 includes a microwave generator 202, and the microwave generator 202 is used to generate microwaves to achieve heating of items. Moreover, the short - circuiting circuit 220 is disposed on the microwave generation circuit 200 and is used to short - circuit the microwave generator 202.

[0101] Specifically, the microwave generator 202 further includes a first switch 204, the power supply circuit 210 includes a second switch 212, and the short - circuit circuit 220 includes a third switch 222. When the first switch 204 is in the conducting state, the second switch 212 is in the conducting state, and the third switch 222 is in the open state, the power supply circuit 210 is conducting, the microwave generating circuit 200 is conducting, and the short - circuit circuit 220 is open.

[0102] Among them, when the main body 110 and the door body 120 are in the closed state, the first switch 204 is in the conducting state, the second switch 212 is in the conducting state, and the third switch 222 is in the open state; when the main body 110 and the door body 120 are in the open state, the first switch 204 is in the open state, the second switch is in the conducting state, and the third switch 222 is in the conducting state, thus ensuring that the cooking appliance 100 can be turned on only when the main body 110 and the door body 120 are in the closed state, improving the safety of the cooking appliance 100.

[0103] The cooking appliance 100 heats food by generating microwaves. The cooking appliance 100 includes a main body 110 and a door body 120. The door body 120 can be opened to place or take out food. When the door body 120 is opened, the microwave generator 202 does not work. After the door body 120 is closed, the first locking hook 130 and the second locking hook 140 of the cooking appliance 100 can trigger the third switch 222, the second switch 212, and the first switch 204 in sequence, so that the microwave generator 202 of the cooking appliance 100 is in a working state. Then, the microwave generator 202 can be controlled through the user control panel. When it is necessary to open the oven door to take out food after cooking, due to the movement of the first locking hook 130 and the second locking hook 140, the first switch 204, the second switch 212, and the third switch 222 are restored, ensuring that the microwave generator 202 is in a non - working state.

[0104] As Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 、 Figure 14 、 Figure 15 and Figure 16 As shown in

[0105] In this embodiment, the first switch 204, the second switch 212, and the third switch 222 are all disposed on the fixing bracket 160. The first switch 204 can be triggered by the second locking hook 140, the second switch 212 can be triggered by the first locking hook 130, and the third switch 222 can be triggered by the slow-closing door structure 170. Thus, the first switch 204, the second switch 212, and the third switch 222 are triggered by different structures, enhancing the safety of the cooking appliance 100.

[0106] As Figure 4 、 Figure 6 、 Figure 8 、 Figure 10 、 Figure 12 、 Figure 13 and Figure 14 shown, in some embodiments, optionally, the cooking appliance 100 further includes a rotating lever 230 disposed on the fixing bracket 160. The rotating lever 230 is rotatably disposed on the fixing bracket 160. When the main body 110 and the door body 120 are in a closed state, the second locking hook 140 triggers the first switch 204 through the rotating lever 230.

[0107] In this embodiment, the cooking appliance 100 further includes a rotating lever 230. The rotating lever 230 is rotatably disposed on the fixing bracket 160. When the main body 110 and the door body 120 are in a closed state, the second locking hook 140 triggers the first switch 204 through the rotating lever 230. That is, the first switch 204 is triggered through the rotating lever 230, increasing the insurance of the first switch 204 being triggered and reducing the possibility of other tools being inserted into the fixing bracket 160 to trigger the first switch 204, further enhancing the safety of the cooking appliance 100.

[0108] As Figure 3 shown, in some embodiments, optionally, the fixing bracket 160 includes a plate body 164 and an end cover 166. The slow-closing door structure 170 is disposed on the plate body 164, the end cover 166 is disposed on the plate body 164, and the third switch 222 is disposed on a side of the end cover 166 facing away from the plate body 164.

[0109] In this embodiment, the fixing bracket 160 includes a plate body 164 and an end cover 166. The slow-closing door structure 170 is disposed on the plate body 164, the end cover 166 is disposed on the plate body 164, and moreover, the third switch 222 is disposed on the end cover 166, thereby reducing the space occupied by the third switch 222 on the plate body 164, reducing the volume of the fixing bracket 160, and making the structures of the fixing bracket 160, the slow-closing door structure 170, and the second locking hook 140 simpler and more stable.

[0110] As Figure 3 、 Figure 4 、 Figure 5 、 Figure 6, Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 and Figure 18 As shown, in some embodiments, optionally, one of the first locking hook 130 and the second locking hook 140 is provided with a slideway 142 , and the other is provided with a sliding portion 138 , and the sliding portion 138 and the slideway 142 are slidably matched.

[0111] In this embodiment, one of the first locking hook 130 and the second locking hook 140 is provided with a slideway 142, and the other is provided with a sliding portion 138. The two are slidably matched through the sliding portion 138 and the slideway 142, so that the first locking hook 130 and the second locking hook 140 form a whole, which is convenient for the positioning and installation of the first locking hook 130 and the second locking hook 140, and is beneficial to improving the assembly accuracy.

[0112] like Figure 12 , Figure 13 and Figure 14 As shown, the stroke of the first locking hook 130 and the second locking hook 140 is e.

[0113] like Figure 17 and Figure 18 As shown, in some embodiments, optionally, the first locking hook 130 includes: a first main body 132, a slide 142 or a sliding portion 138 is arranged at one end of the first main body 132, and the reset member 150 and the end of the first main body 132 facing away from the second door hook are abutted against each other; a first hook 134 is arranged on the first main body 132, and the first hook 134 is used to cooperate with the limiting member; a wrench 136 is arranged on the first main body 132, and at least a portion of the wrench 136 is exposed to the door body 120.

[0114] In this embodiment, the first locking hook 130 includes a first main body 132, a first hook 134 and a wrench 136. The first hook 134 and the wrench 136 are respectively arranged on both sides of the first main body 132, so that the first hook 134 and the locking plate 190 in the main body 110 cooperate with each other, and the wrench 136 is exposed outside the door body 120 from the other side, so as to facilitate the user to operate the wrench 136.

[0115] Furthermore, the reset member 150 abuts against a side of the first body 132 facing away from the second locking hook 140 , so that the first locking hook 130 can be reset toward the second locking hook 140 .

[0116] like Figure 3 , Figure 4 , Figure 5 , Figure 6, Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 and Figure 18 As shown in Figure 18 , in some embodiments, optionally, the side of the head of the first hook 134 facing the first body 132 is a vertical planar structure.

[0117] As Figure 17 shown, in some embodiments, optionally, the door body 120 includes: a door panel 122; a handle 124 provided on the door panel 122, the wrench 136 protruding from the door panel 122, and the wrench 136 and the handle 124 being opposite to each other.

[0118] In this embodiment, the door body 120 includes a door panel 122 and a handle 124. The handle 124 is provided on the door panel 122, the wrench 136 protrudes from the door panel 122, and the wrench 136 and the handle 124 are opposite to each other. Thus, the user can open the door after moving the wrench 136 with only one hand, and the wrench 136 can also be hidden, reducing the possibility of accidental touch of the wrench 136.

[0119] As Figure 17 shown, the wrench 136 of the first locking hook 130 is only on the upper hook, located outside the door body 120, and the wrench 136 and the handle 124 form a vertically liftable component. Its structure is simple, has little influence on the door body 120, and only a few openings need to be added to the door body 120, facilitating the implementation of the child lock function of two-step door opening.

[0120] As Figure 18 shown, the first locking hook 130 and the second locking hook 140 are in sliding fit. Among them, the second locking hook 140 is fixed on the door body 120, and the first locking hook 130 and the second locking hook 140 are in sliding fit, enabling the first locking hook 130 to slide up and down.

[0121] An installation seat is provided on the first locking hook 130, and the reset member 150 is arranged on the installation seat. Moreover, the reset member 150 can push the first locking hook 130 to move up and down. The reset member 150 is installed between the first locking hook 130 and the fixed block of the door body 120. After installation, the reset member 150 is in a preloaded state, continuously providing a downward thrust to the first locking hook 130, ensuring that the first locking hook 130 can smoothly cross the guiding surface 192 of the locking piece 190 and then can also maintain the pressing on the second switch 212.

[0122] Among them, the stroke of the reset member 150 is 5 mm to 7 mm, which can not only ensure that the first locking hook 130 can smoothly cross the guiding surface 192 of the locking piece 190, but also maintain continuous pressing on the second switch 212 subsequently. At the same time, when performing two-step door opening, lifting the first locking hook 130 only needs to overcome a thrust within 5 N, so that the first locking hook 130 can move vertically upward by 5 mm to 7 mm, higher than the locking piece 190, and then the two-step door opening action can be smoothly completed.

[0123] When the head of the first locking hook 130 is in a state of locking the stroke of the end face of the door body 120 and the locking piece 190 vertically, when directly pulling the door body 120, at least a force of more than 50 N is required to directly open the door body 120, so that children cannot directly open the cooking appliance 100, ensuring the safety of the child lock function.

[0124] In some embodiments, optionally, during the closing process of the microwave oven, when the door body 120 is in a small-angle state, gently pushing the door body 120 with a force within 4 N can start the slow closing process of the door body 120 and reach the final closed state. The process is that the door body 120 drives the first locking hook 130 and the second locking hook 140 to rotate towards the main body 110. As Figure 6 shown, at this time, the second locking hook 140 first touches the driving lever 172. Under the inertial thrust of the door body 120, the balance state in which the first elastic member 182 and the second elastic member 184 keep the driving lever 172 at the entrance of the second locking hook 140 is broken, so that the first elastic member 182 and the second elastic member 184 rotate towards the inside of the main body 110, thereby driving the driving lever 172 to rotate inward, and then the driving lever 172 pulls the second locking hook 140 to move inward.

[0125] As the stroke of the second locking hook 140 moving inward increases, the first locking hook 130 also follows the rotation of the door body 120 towards the main body 110. The first hook 134 of the first locking hook 130 begins to touch the locking piece 190. As Figure 7 and Figure 8 shown, during the closing process, the first locking hook 130 contacts the guiding surface 192 of the locking piece 190.

[0126] Finally, under the pulling force of the first elastic member 182 and the second elastic member 184, the driving lever 172 rotates, pushing the second locking hook 140 to continue moving inward. At the same time, the second locking hook 140 touches the rotating lever 230. After the rotating lever 230 rotates by a small angle, the rotating lever 230 triggers the first switch 204, so that the short-circuit circuit 220 is in an open state. And at this time, the first locking hook 130 has already crossed the guiding surface 192 of the locking piece 190 under the thrust of the second locking hook 140 and maintains the triggering of the second switch 212 under the pressure of the reset member 150. The state when the door is closed in place is as Figure 9 、Figure 10 and Figure 11 shown.

[0127] Furthermore, during the door closing process, the driving lever 172 is first rotated, and the boss on the driving lever 172 rotates and contacts the third switch 222 installed on the end cover 166. Subsequently, the first lock hook 130 passes over the guide surface 192 of the lock plate 190, and the end surface of the first lock hook 130 facing away from the main body 110 forms a locking fit with the lock plate 190, thereby realizing the child lock. Under the thrust of the reset member 150, the first lock hook 130 keeps contacting the second switch 212, so that the power supply circuit 210 is in a conducting state. Finally, the second lock hook 140 pushes the rotating lever 230 to rotate through a small angle, contacts the first switch 204, so that the microwave generating circuit 200 is in a conducting state. At this point, the main body 110 and the door body 120 are in a closed state, the first lock hook 130 and the second lock hook 140 keep triggering the first switch 204, the second switch 212 and the third switch 222, and the microwave generating circuit 200 is in a controllable state.

[0128] During the door opening process, the first lock hook 130 and the second lock hook 140 are opened in two steps. The first is the process of releasing the child lock function. The user pulls the wrench 136 of the first lock hook 130 on the handle 124 of the door body 120 with one hand, so that the first lock hook 130 can move upward by 4mm to 10mm. After the first lock hook 130 is pulled, the first hook 134 of the first lock hook 130 is higher than the lock plate 190. At the same time, because the first lock hook 130 leaves, the second switch 212 is reset, and the power supply circuit 210 is in an open circuit state. Secondly, in the door opening process, the user pulls the handle 124 of the door body 120 to open the door body 120 outwards. At this time, because the first lock hook 130 is higher than the lock plate 190, it exits the locked state, so that the door body 120 can be opened. At the same time, as the first lock hook 130 is pulled out, the second lock hook 140 is also pulled outward at the same time. It only needs to overcome the horizontal force of the first elastic member 182 and the second elastic member 184 (which can be less than 22N), the second lock hook 140 moves outward, the first switch 204 is reset, the first switch 204 resets the rotating lever 230, and the microwave generating circuit 200 is in an open circuit state. Finally, when the second lock hook 140 is about to exit the main body 110, the driving lever 172 is brought back to the entrance, the forces of the first elastic member 182 and the second elastic member 184 are balanced, so that the driving lever 172 is in a balanced state. At this time, the boss of the driving lever 172 has been separated from the third switch 222, and the short circuit 220 is in a conducting state, preventing the microwave generating circuit 200 from being accidentally turned on. After the first lock hook 130 and the second lock hook 140 are both moved out of the main body 110, the door opening process of the cooking utensil 100 is completed, the microwave generating circuit 200 is disconnected, and is in a protection state of the short circuit 220.

[0129] Specifically,Figure 12 As shown, when closing the door, as the second locking hook 140 is pushed inward by the driving lever 172 and moves inward, at the same time, the first locking hook 130 also keeps moving inward. When the head of the first locking hook 130 contacts the guiding surface 192 of the locking piece 190, the upward reaction force of the guiding surface 192 causes the first locking hook 130 to move upward. And since the first locking hook 130 and the second locking hook 140 are nested with each other, thus, the sliding pair formed by the two makes the first locking hook 130 can only slide up and down on the door body 120, without rotation or front-back offset. As Figure 13 、 Figure 14 and Figure 15 shown, the first locking hook 130 is driven to cross over the locking piece 190, and the thrust of the resetting member 150 enables the first locking hook 130 to continuously keep pressing on the second switch 212. As Figure 16 shown, when opening the door, the first step is that the user's hand pulls up the wrench 136 of the first locking hook 130 on the handle 124, so that the head of the first hook 134 of the first locking hook 130 is higher than the locking piece 190. The second step is that the user pulls the handle 124, so that the door body 120 is opened outward. The first locking hook 130 is pulled out as the door body 120 rotates outward. At this time, the process of unlocking the child lock and opening the door is completed.

[0130] The cooking appliance 100 provided by the present utility model, on the basis of soft closing and gentle closing of the door, newly adds a child lock function with two-step opening actions. It adopts a compression spring, the first locking hook 130 is added with a wrench 136 for pulling up, the first locking hook 130 is vertically guided in the slideway 142 of the fixed second locking hook 140, and the inner end surface of the head of the first locking hook 130 is designed to be vertical, which is convenient for the locking between the locking piece 190 and the first locking hook 130. And it is convenient for the child lock function to be operable with one hand and open the door smoothly in two steps. The structure is simple, safe and reliable, and realizes a reliable and simple child lock function only with a very small increase in cost.

[0131] The cooking appliance 100 can be a microwave oven, an oven or a steam box, etc.
