In the process of closing the door, the first lock hook can touch the driving lever, and drive the driving lever to move after a certain stroke, and the balance between the driving assembly and the driving lever is broken, the driving assembly drives the driving lever to move, and the driving lever hooks the first lock hook, thereby driving the door body to move and close the door. In the process of opening the door, the door body drives the first lock hook to move, and the first lock hook drives the driving lever to move. Under normal circumstances, after the door body is fully opened, the driving lever can be offset against the bracket, so that the force of the driving lever is balanced, and the driving assembly will not drive the driving lever to move, so that when the door is closed again, the driving assembly can drive the door body to move through the driving lever.

[0008] The cooking utensil also includes a first limit member, a guide member and a first reset member, which are arranged on the bracket, the first limit member is rotatable relative to the bracket, the guide member is movable relative to the bracket, the first limit member is connected to the guide member, and the first limit member is also connected to the first reset member.

[0010] During the process of closing the door, the first lock hook first touches the guide member, the guide member moves, and drives the first limit member to rotate, so that the first limit member and the driving lever are separated, and then the first lock hook touches the driving lever. After the driving lever moves a certain distance, the driving assembly drives the driving lever to move, the driving lever drives the first lock hook to move, and the first lock hook drives the door body to move, thereby achieving door closing.

[0011] During the door opening process, the door body drives the first lock hook to move, and the first lock hook drives the driving lever to move, and during the movement of the first lock hook, the guide member is always against the first lock hook. After the door body is fully opened, the guide member and the first limit member are subjected to the force of the first reset member, resulting in a stroke, so that the first limit member and the driving lever are against each other, and the first limit member and the driving lever are against each other, thereby reducing the possibility of the driving lever rebounding, thereby ensuring the reliability of closing the door of the cooking appliance again.

Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0083] Refer to the following Figures 1 to 32 The cooking device 100 provided according to some embodiments of the present invention is described.

[0084] like Figure 1 As shown, according to some embodiments of the present invention, the present invention provides a cooking appliance 100, including: a main body 110 and a door body 120, the main body 110 and the door body 120 are hinged, and thus the door body 120 can be opened and closed.

[0085] A lock hook assembly 130 is arranged on the door body 120, and the lock hook assembly 130 includes a first lock hook 132. A bracket 140 is arranged on the main body 110. The cooking appliance 100 also includes a driving assembly 170, a driving lever 160, a first limit member 180, a guide member 190 and a first reset member 200 arranged on the bracket 140. The driving lever 160 is rotatably arranged on the bracket 140. The driving assembly 170 is arranged on the bracket 140 and is connected to the driving lever 160. The driving assembly 170 can drive the driving lever 160 to rotate. The first reset member 200 is connected to the bracket 140, and the first reset member 200 is also connected to the first limit member 180. The guide member 190 is movable relative to the bracket 140 and abuts against the first limit member 180.

[0086] like Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, when the door body 120 is opened, the first reset member 200 supports the first limit member 180, the first limit member 180 supports the guide member 190, the first limit member 180 and the driving lever 160 are offset against each other to limit the rebound of the driving lever 160, so that the driving lever 160 is in a state of force balance.

[0087] When the door body 120 is closed, the first lock hook 132 extends in, the first lock hook 132 squeezes the guide member 190, the guide member 190 squeezes the first limit member 180, the first limit member 180 rotates and separates from the driving lever 160, and the first reset member 200 is deformed.

[0088] In the process of closing the door, the first lock hook 132 may first touch the guide member 190, so that the first stopper 180 and the driving lever 160 are separated, and then the first lock hook 132 touches the driving lever 160, and the driving assembly 170 drives the driving lever 160 to move, and the driving lever 160 hooks the first lock hook 132, thereby driving the door body 120 to move, and the door is closed. In the process of opening the door, the door body 120 drives the first lock hook 132 to move, and the first lock hook 132 drives the driving lever 160 to move. Under normal circumstances, after the door body 120 is fully opened, the driving lever 160 can be against the bracket 140, the guide member 190 and the first lock hook 132 are separated, and the guide member 190 and the first stopper 180 are reset under the action of the first reset member 200, so that the first stopper 180 and the driving lever 160 are against each other.

[0089] The cooking device 100 provided by the present invention comprises 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, the door body 120 can be opened and closed.

[0090] The cooking appliance 100 further includes a lock hook assembly 130, a bracket 140, a driving lever 160 and a driving assembly 170. The lock hook assembly 130 is disposed on the door body 120.

The driving assembly 170 and the driving lever 160 are connected, and the driving assembly 170 is used to drive the driving lever 160 to move. In the process of closing the door, the first lock hook 132 can touch the driving lever 160, and drive the driving lever 160 to move a certain stroke. After that, the balance between the driving assembly 170 and the driving lever 160 is broken, and the driving assembly 170 drives the driving lever 160 to move. The driving lever 160 hooks the first lock hook 132, thereby driving the door body 120 to move, and the door is closed. During the door opening process, the door body 120 drives the first lock hook 132 to move, and the first lock hook 132 drives the driving lever 160 to move. Under normal circumstances, after the door body 120 is fully opened, the driving lever 160 can be offset against the bracket 140, so that the force on the driving lever 160 is balanced, and the driving component 170 will not drive the driving lever 160 to move, so that when the door is closed again, the driving component 170 can drive the door body 120 to move through the driving lever 160.

[0091] The cooking utensil 100 further includes a first position-limiting member 180, a guide member 190 and a first resetting member 200.

The hook 164 is used to cooperate with the first locking hook 132, and the support arm 166 is used to cooperate with the first limiting member 180.

[0107] Specifically, in the process of closing the door, the first lock hook 132 first touches the guide member 190, the guide member 190 moves, and drives the first limit member 180 to rotate and separate from the support arm 166, and then the first lock hook 132 touches the hook 164, and after the driving lever 160 moves a certain stroke, the hook 164 hooks the first lock hook 132, the driving assembly 170 drives the driving lever 160 to move, the driving lever 160 drives the first lock hook 132 to move, and the first lock hook 132 drives the door body 120 to move, thereby achieving door closing.

[0108] During the door opening process, the door body 120 drives the first lock hook 132 to move, and the first lock hook 132 drives the driving lever 160 to move. During the movement of the first lock hook 132, the guide member 190 is always against the first lock hook 132.

[0109] The driving lever 160 has a simple structure and high reliability.

[0110] like Fig.29 and Fig.30As shown, in some embodiments, optionally, the first limiting member 180 includes a rotating shaft 182, a cross bar 184, a limiting rod 186 and a pressure rod 188, and the rotating shaft 182 and the bracket 140 are rotatably connected, wherein the rotating shaft 182 can be passed through the mounting hole 144 of the plate body 142, the cross bar 184 is arranged on the rotating shaft 182, the limiting rod 186 is arranged on the cross bar 184 for cooperating with the driving lever 160, the pressure rod 188 is arranged on the cross bar 184, and the guide member 190 and the pressure rod 188 are against each other, wherein the pressure rod 188 is located between the rotating shaft 182 and the limiting rod 186, and the pressure rod 188 and the limiting member are separated.

[0111] In this embodiment, the first limiting member 180 includes a rotating shaft 182, a cross bar 184, a limiting rod 186 and a pressure rod 188, wherein the cross bar 184 is arranged on the rotating shaft 182, the limiting rod 186 and the pressure rod 188 are arranged on the cross bar 184, the pressure rod 188 cooperates with the guide member 190, so that the guide member 190 and the pressure rod 188 are abutted against each other, and then after the guide member 190 moves, the pressure rod 188 moves, so that the cross bar 184 rotates, the limiting rod 186 is used to abut against the first locking hook 132, and the rotating shaft 182 is rotatably arranged on the bracket 140.

Then, the first elastic member 172 and the second elastic member 174 apply forces in different directions respectively. When the door body 120 is opened, the driving lever 160 is in a balanced position. At this time, the driving lever 160 is in a balanced position. The movable lever 160 itself is under balanced force, and is restricted by the first limit member 180 so that the driving lever 160 stays in a balanced position, wherein the driving lever 160 can be offset against the bracket 140 at the balanced position, and the first locking hook 132 causes the driving lever 160 to be out of a balanced state, so that the first limit member 180 is out of the driving lever 160. At this time, the first elastic member 172 and the second elastic member 174 drive the driving lever 160 to rotate, so that the driving lever 160 drives the first locking hook 132 to move, thereby achieving a slow door closing effect.

[0143] One end of the second elastic member 174 abuts against the bracket 140 , and the other end abuts against the second limiting member 210 , thereby providing a restoring force for the second limiting member 210 .

[0144] The second position-limiting member 210 is disposed on the bracket 140 . The inclined surface of the second position-limiting member 210 provides a reverse force to slow down the door body 120 when closing the door, and provides a certain door-opening force when opening the door.

[0145] When closing the door, Fig. 9 , Fig.10 , Fig.11 , Fig.12 , Fig.13 , Fig.14 , Fig.15 , Fig.16 , Fig.19 , Fig. 20 , Fig. 22 , Fig.23 and Fig.24 As shown, when the first locking hook 132 extending from the door 120 of the cooking appliance 100 passes through the hole on the front plate of the main body 110, the main body 110 is locked. Fig.14 As shown, the first locking hook 132 first presses down the guide member 190 to drive the guide member 190 to move downward, and the guide member 190 drives the first limiting member 180 to rotate until the first locking hook 132 completely presses down the guide member 190, at which time the limiting rod 186 of the first limiting member 180 completely releases the driving lever 160.

[0146] Then, the first locking hook 132 touches the surface of the hook 164 of the driving lever 160, breaking the balance of the torque provided by the first elastic member 172 and the second elastic member 174 connected to the driving lever 160. Fig.15 As shown, at this time, the driving lever 160 rotates under the action of the torque provided by the first elastic member 172 and the second elastic member 174, and the driving lever 160 and the first locking hook 132 are engaged with each other, and then the driving lever 160 rotates under the action of the torque provided by the first elastic member 172 and the second elastic member 174, and slowly rotates under the action of the damper 230, as shown in FIG. Fig.17 As shown, the driving lever 160 pulls the first locking hook 132 to move linearly during the rotation process, so that the door body 120 is slowly closed. When the door is fully closed, the first locking hook 132 drives the rotating lever 270 to rotate, as shown in FIG. Fig.18 As shown, when the door is closed, the rotating lever 270 triggers the first switch 244 and the second switch 252. In addition, during the door closing process, when the second lock hook 134 contacts the inclined surface of the second stopper 210, as shown in FIG. Fig. 20 and Fig.21 As shown, since the reaction force on the second limiting member 210 has a horizontal leftward component, it has a certain deceleration effect on the closing of the door.

[0147] When opening the door, the first lock hook 132 pulls the hook 164 of the driving lever 160, causing the driving lever 160 to rotate. When the driving lever 160 is pulled to a specific position, the second lock hook 134 disengages from the driving lever 160, the door body 120 opens, and the driving lever 160 leans against the side of the bracket 140 of the door body 120. At this time, the first limiter 180 rotates in the opposite direction and presses on the driving lever 160 under the action of the torque of the first reset member 200. The limiter rod 186 on the first limiter 180 blocks the driving lever 160 to prevent the driving lever 160 from rotating counterclockwise. The guide member 190 slides upward and returns to the initial position. As described above, the cooking utensil 100 provided by the utility model solves the problem that the driving lever 160 rotates abnormally to the right and cannot close the door normally.

[0148] The cooking device 100 provided by the utility model has a slow door closing effect, can reduce the door closing noise, and solves the problem that the slow door closing structure of the existing cooking device 100 cannot close the door normally due to abnormal operation, thereby improving the reliability of the cooking device 100.

[0149] The cooking appliance 100 may be a microwave oven, an oven, a steamer, or the like.
