For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] The following is for reference. Figures 1-9 This invention describes an interlocking assembly for a door lock switch according to an embodiment of the present invention.

[0039] Reference Figure 1 , Figure 2 and Figure 3 It should be noted that the door lock switch 1000 includes an interlocking assembly 100 and a door hook 200. The door hook 200 is movable relative to the interlocking assembly 100. One of the interlocking assembly 100 and the door hook 200 is used to be installed on the housing 300 of the cooking appliance 2000, and the other of the interlocking assembly 100 and the door hook 200 is used to be installed on the door 400 of the cooking appliance 2000. The interlocking assembly 100 can lock the door hook 200 to restrict the movement of the door 400, and the interlocking assembly 100 can also unlock the door hook 200, so that the door 400 can move relative to the housing 300.

[0040] The interlocking assembly of the door lock switch according to an embodiment of the present utility model includes: a drive assembly 1 and a rotating locking member 2. The drive assembly 1 includes a rotatable output member, and the rotating locking member 2 is connected to the output member. The drive assembly 1 operates to drive the rotating locking member 2 to rotate through the output member. The rotating locking member 2 rotates to switch between the locked state of locking the door hook 200 and the unlocked state of unlocking the door hook 200.

[0041] In this embodiment of the invention, the interlocking component 100 can drive the rotating locking member 2 from the locked state to the unlocked state via the driving component 1, thereby achieving automatic unlocking of the door hook 200. In some application scenarios, the interlocking component 100 is installed in the housing 300 of the cooking device 2000, which has a cooking space with a placement opening. The door hook 200 is installed in the door 400 of the cooking device 2000 and can move together with the door 400. When the cooking device 2000 is cooking food, the door 400 closes the placement opening, and the rotating locking member 2 of the interlocking component 100 is locked to restrict the movement of the door hook 200, so that the door 400 can stably close the placement opening. After the cooking device 2000 finishes cooking, the rotating locking part 2 can be driven to rotate by the drive component 1 of the interlocking component 100. Under the drive of the drive component 1, the rotating locking part 2 rotates to the unlocked state, so that the door 400 can automatically move to open the placement opening under the action of elasticity, gravity or other forces, realizing the automatic opening of the cooking device 2000 without the need for the user to open the door manually, avoiding the risk of the user being burned.

[0042] According to the interlocking component of the door lock switch in this embodiment of the present invention, the drive component 1 can drive the rotating locking member 2 to rotate from the locked state to the unlocked state, thereby realizing the automatic unlocking of the door hook 200; the cooking device 2000 equipped with the door lock switch 1000 in this embodiment of the present invention can realize automatic door opening, avoiding the risk of users being scalded.

[0043] In some embodiments, the drive assembly 1 includes a motor, which includes a stator, a rotor, and a motor shaft 11. The rotor is rotatable relative to the stator and cooperates with the motor shaft 11 to drive the motor shaft 11 to rotate. The motor shaft 11 is formed as an output component.

[0044] The driving component in this embodiment is a motor, which can directly drive the rotation locking component 2 to rotate through the motor shaft 11. The driving component has a simple structure, is easy to assemble, and helps to improve the production efficiency of the interlocking components.

[0045] When the drive assembly 1 is not powered, if the motor shaft 11 is driven to rotate by an external force, the internal structure of the drive assembly 1 will cause the motor shaft 11 to experience torsional resistance. In this embodiment, the interlocking assembly 100 can also provide a buffering effect for the closing of the door 400 through this torsional resistance. In some application scenarios, when a user needs to close the door, they push the door 400 to the closed position. During this process, the door hook 200 moves along with the door 400. When the door hook 200 contacts the rotating locking member 2, it pushes the rotating locking member 2 towards the locked state. Because the rotating locking member 2 is connected to the motor shaft 11, the rotating locking member 2 experiences torsional resistance when rotating, thereby reducing the rotation speed of the rotating locking member 2, which in turn reduces the closing speed of the door 400, preventing the door 400 from colliding with the door and reducing noise during closing.

[0046] It should be noted that the torsional resistance experienced by the motor shaft 11 when the drive assembly 1 is not powered may include: electromagnetic resistance between the stator and the rotor, and mechanical frictional resistance when the motor shaft rotates. This application does not limit this.

[0047] In other embodiments, the drive assembly includes an electric drive element and a transmission assembly. The transmission assembly includes an input element connected to the electric drive element and an output element connected to the rotation lock element 2. The electric drive element is a device that converts electrical energy into mechanical energy, and the transmission assembly is used to transmit the power output by the electric drive element to the rotation lock element through the output element, thereby driving the rotation lock element to rotate.

[0048] For example, the electric drive component can be a motor adapted to drive the input component to rotate, and the transmission component can be a linkage assembly or a gear assembly; the electric drive component can also be an electric actuator adapted to drive the input component to move in a straight line, and the transmission component can be a crank-slider assembly; the electric drive component can also be other devices, and the transmission component can also be other transmission mechanisms, as long as the output component can rotate, and this application does not impose any limitations on this.

[0049] Reference Figure 2 , Figure 3 and Figure 4 In some embodiments, the door hook 200 is provided with a hanging hole 210, and the rotating locking member 2 is provided with a locking hook 21. In the locked state, the locking hook 21 is engaged with the hanging hole 210, and in the unlocked state, the locking hook 21 is disengaged from the hanging hole 210.

[0050] When the door 400 moves toward the direction of closing the placement opening, the door hook 200 moves toward the direction of approaching the interlocking assembly 100. When the door 400 completely closes the placement opening, the rotating locking member 2 rotates to the locked state. The locking hook 21 of the rotating locking member 2 is inserted into the hanging hole 210 of the door hook 200 and is engaged with the door hook 200, which restricts the movement of the door hook 200, that is, restricts the movement of the door 400, so that the door 400 can stably close the placement opening.

[0051] When the door needs to be opened, the drive assembly 1 can drive the rotating locking member 2 to rotate to the unlocked state. The lock hook 21 disengages from the hanging hole 210, releasing the restriction on the door hook 200. The door 400 can then automatically move to open and accommodate the opening under the action of elasticity, gravity, or other forces. Besides unlocking via the drive assembly 1, the user can also pull the door 400, which pulls the door hook 200. The door hook 200 applies a force to the lock hook 21, causing the rotating locking member 2 to overcome the internal resistance of the drive assembly 1 and rotate towards the unlocked state. The lock hook 21 disengages from the hanging hole 210, thereby opening the door 400.

[0052] In this embodiment of the utility model, the method of locking the door hook 200 by rotating the locking member 2 is simple. It can not only drive the rotating locking member 2 to rotate to the unlocked state by the driving component 1, but also does not affect the user's manual opening of the door.

[0053] In some specific embodiments, the rotating locking member 2 further includes a baffle 22, and the door hook 200 is adapted to push the rotating locking member 2 from the unlocked state to the locked state through the baffle 22.

[0054] When the door 400 moves toward the direction of closing the placement opening, the door hook 200 moves toward the direction of approaching the interlocking assembly 100. After the door hook 200 contacts the baffle 22, the door hook 200 continues to move toward the direction of closing the placement opening along with the door 400. The door hook 200 pushes the baffle 22 to make the rotating locking member 2 rotate to the locked state, so that the locking hook 21 of the rotating locking member 2 is inserted into the hanging hole 210 of the door hook 200 and hooked together with the door hook 200.

[0055] When the drive assembly 1 drives the rotating locking member 2 to rotate toward the unlocked state, the lock hook 21 gradually disengages from the hanging hole 210, and at the same time the baffle 22 pushes the door hook 200 away from the interlock assembly 100, so that the door body 400 moves toward the open placement opening, which is conducive to realizing the automatic opening of the cooking equipment 2000.

[0056] Through the above technical solution, the closing of the door 400 and the locking of the door hook 200 by the interlocking component 100 are synchronized. When the door 400 is completely closed and the placement opening is closed, the interlocking component 100 has already locked the door hook 200, ensuring the reliability of the door 400 in closing the placement opening. It can also be realized that when the interlocking component 100 unlocks the door hook 200, rotating the locking member 2 pushes the door hook 200 to move through the baffle 22, thereby realizing the automatic opening of the door 400.

[0057] In some embodiments, the interlocking assembly 100 further includes a fixed bracket 3 and an elastic element 4, the elastic element 4 being connected to the fixed bracket 3 and the rotary locking element 2 respectively. The elastic element 4 has a first state and a second state. In the first state, the force applied by the elastic element 4 to the rotary locking element 2 causes the rotary locking element 2 to tend to rotate toward the locked state. In the second state, the force applied by the elastic element 4 to the rotary locking element 2 causes the rotary locking element 2 to tend to rotate toward the unlocked state.

[0058] When the rotating locking member 2 rotates from the unlocked state to the locked state, the rotating locking member 2 drives the elastic member 4 to switch from the second state to the first state. That is to say, after the rotating locking member 2 rotates from the unlocked state to the locked state by a certain angle, the elastic member 4 switches to the first state, and the elastic member 4 in the first state can assist the rotating locking member 2 to rotate towards the locked state.

[0059] During the closing process of the door 400, the door hook 200 pushes the rotating locking member 2 from the unlocked state to the locked state. At this time, the torsional resistance of the motor shaft 11 buffers the closing speed of the door 400, preventing the door 400 from colliding with the housing 300. After the rotating locking member 2 rotates from the unlocked state to the locked state by a certain angle, the elastic member 4 switches to the first state. The elastic member 4 in the first state can assist the rotating locking member 2 to continue rotating towards the locked state. The force applied by the elastic member 4 in the first state to the rotating locking member 2 ensures that the rotating locking member 2 can overcome the torsional resistance of the motor shaft 11, so that the door 400 can move stably in the direction of closing the placement opening until the placement opening is completely closed. In other words, through the cooperation of the motor and the elastic member 4, a buffered closing can be achieved, with small fluctuations in the closing thrust and smooth closing.

[0060] Furthermore, when the door 400 is fully closed and the opening is placed, the elastic element 4 in the first state exerts a force on the rotating locking element 2, which allows the locking hook 21 to tighten the door hook 200, reducing the gap between the door 400 and the cabinet 300, reducing the possibility of gas or microwave leakage between the door 400 and the cabinet 300, and improving the safety of using the cooking equipment 2000.

[0061] When the rotating locking member 2 rotates from the locked state to the unlocked state, it drives the elastic member 4 to switch from the first state to the second state. That is, after the rotating locking member 2 rotates from the locked state to the unlocked state by a certain angle, the elastic member 4 switches to the second state. The elastic member 4 in the second state can assist the rotating locking member 2 in rotating towards the unlocked state, which can increase the speed at which the baffle 22 pushes the door hook 200, and help to increase the speed at which the door 400 opens to place the opening.

[0062] In some embodiments, the fixed bracket 3 is provided with a first mounting part 31, the rotating locking member 2 is provided with a second mounting part 23, and the elastic member 4 is constructed as a torsion spring, with both ends of the torsion spring inserted into the first mounting part 31 and the second mounting part 23 respectively.

[0063] When the rotating locking member 2 rotates, it will drive the second mounting part 23 to rotate, thereby changing the direction of the force applied by the torsion spring to the rotating locking member 2, so that the elastic member 4 can switch between the first state and the second state.

[0064] In this embodiment of the utility model, the elastic element 4 has a simple structure, is easy to install, and reduces the cost of the interlocking assembly 100.

[0065] In some embodiments, the drive assembly 1 is disposed on the fixed bracket 3, and the rotation locking member 2 is located between the fixed bracket 3 and the drive assembly 1.

[0066] In this embodiment of the invention, the drive assembly 1 is mounted on the fixed bracket 3, which helps to improve the stability of the drive assembly 1. Furthermore, the rotating locking member 2 is located between the fixed bracket 3 and the drive assembly 1, and the fixed bracket 3 and the drive assembly 1 can shield the rotating locking member 2, reducing the possibility of external objects affecting the rotation of the rotating locking member 2, and improving the reliability of the interlocking assembly in locking and unlocking the door hook 200.

[0067] In some embodiments, the fixed bracket 3 is provided with a support portion 32 extending toward the drive assembly 1, and the drive assembly 1 is fixed to the support portion 32. A movable space for the rotation locking member 2 is formed between the fixed bracket 3, the support portion 32, and the drive assembly 1.

[0068] In this embodiment of the present invention, the fixed bracket 3 is provided with a support portion 32 extending toward the drive component 1, which improves the convenience of connecting the drive component 1 and the fixed bracket 3 and is conducive to improving the assembly efficiency of the interlocking component 100.

[0069] In some embodiments, the fixed bracket 3 is provided with a first mating hole 33, and the rotating locking member 2 is provided with a mating post 24. The mating post 24 is rotatably disposed in the first mating hole 33 so that the rotating locking member 2 is rotatably connected to the fixed bracket 3. A second mating hole 25 is provided on the side of the rotating locking member 2 away from the mating post 24, and the motor shaft 11 is inserted into the second mating hole 25 to drive the rotating locking member 2 to rotate. In this embodiment of the present invention, the connection method of the fixed bracket 3, the rotating locking member 2 and the drive assembly 1 is simple and easy to assemble.

[0070] Reference Figure 4 and Figure 7 In some embodiments, the fixing bracket 3 further includes a front end plate 34, which is adapted to be fixed to the housing 300 of the cooking equipment 2000. The front end plate 34 is provided with a clearance hole 341, and in the locked state, the locking hook 21 and the baffle 22 are positioned opposite to the clearance hole 341. The front end of the door hook 200 can pass through the clearance hole 341 and push the baffle 22 to cause the rotating locking member 2 to rotate toward the locked state.

[0071] In this embodiment of the utility model, the installation method of the fixed bracket 3 is simple and facilitates the installation of the interlocking assembly 100.

[0072] In some embodiments, a micro switch is also provided on the fixed bracket 3, and a trigger is provided on the rotating locking member 2. When the rotating locking member 2 switches between the locked state and the unlocked state, the trigger cooperates with the micro switch to switch between opening and closing the micro switch.

[0073] The micro switch can be connected to other components of the cooking equipment 2000, so that the opening and closing state of the door 400 of the cooking equipment 2000 can control the working state of other components of the cooking equipment 2000, which is beneficial to improving the intelligence and safety of the cooking equipment 2000.

[0074] In some specific embodiments, there may be two, three, or other numbers of microswitches, and this invention does not limit this number.

[0075] In some specific embodiments, the micro switch can be detachably mounted on the fixed bracket 3 by means of snap-fit, screw-fit, or plug-in connection to facilitate the maintenance of the micro switch.

[0076] In some embodiments, the rotating locking member 2 is provided with a plurality of reinforcing ribs 26. By providing a plurality of reinforcing ribs 26, the strength of the rotating locking member 2 is effectively improved, which is beneficial to extending the service life of the interlocking assembly 100.

[0077] The door lock switch 1000 according to an embodiment of the present utility model includes: a door hook 200 and the interlocking component 100 in the above technical solution.

[0078] According to the door lock switch 1000 of this utility model embodiment, the interlocking component 100 can drive the rotating locking member 2 to rotate from the locked state to the unlocked state through the driving component 1, so as to realize the automatic unlocking of the door hook 200; the cooking device 2000 equipped with the door lock switch 1000 of this utility model embodiment can realize automatic door opening, avoiding the risk of users being burned; and this utility model embodiment can also use the torsional resistance encountered when the motor shaft 11 rotates to buffer the closing speed of the door body 400, avoid the door body 400 from hitting the door body 400, and reduce the noise when closing the door.

[0079] The cooking device 2000 according to an embodiment of the present invention includes: a door lock switch 1000, a housing 300, a cooking component, and a door 400 as described above. The housing 300 has a cooking space and a placement opening communicating with the cooking space. The door 400 is movably disposed in the housing 300 for closing and opening the placement opening. An interlocking component 100 of the door lock switch is disposed in the housing 300, and a door hook 200 of the door lock switch is disposed in the door 400. When the door 400 closes the placement opening, the interlocking component 100 locks the door hook 200.

[0080] It should be noted that the cooking component can be a microwave generator, heating element, steam generator, or other components that can be used to cook food, and this utility model does not limit this.

[0081] When the cooking device 2000 is cooking food, the door 400 closes the placement opening, and the rotation lock 2 of the interlocking assembly 100 is locked to restrict the movement of the door hook 200, allowing the door 400 to stably close the placement opening. After the cooking device 2000 finishes cooking, the rotation lock 2 can be driven to rotate by the drive assembly 1 of the interlocking assembly 100. Under the drive of the drive assembly 1, the rotation lock 2 rotates to the unlocked state, allowing the door 400 to automatically open the placement opening under the action of elasticity, gravity, or other forces. This achieves automatic opening of the cooking device 2000, eliminating the need for manual opening by the user and avoiding the risk of burns.

[0082] According to the cooking device 2000 of this utility model embodiment, the interlocking component 100 can drive the rotating locking member 2 from the locked state to the unlocked state through the driving component 1, so as to realize the automatic unlocking of the door hook 200; the cooking device 2000 can realize automatic door opening, avoiding the risk of user being burned; and this utility model embodiment can also use the torsional resistance encountered when the motor shaft 11 rotates to buffer the closing speed of the door body 400, avoid the door body 400 from hitting the door body 400, and reduce the noise when closing the door.

[0084] In this embodiment of the invention, the door 400 is rotatably connected to the bottom of the housing 300, and the interlocking assembly 100 is disposed at the top of the housing 300. When the door 400 is closed and the opening is placed, the door 400 is parallel to the vertical direction. When it is necessary to open the door, the drive assembly 1 drives the rotating locking member 2 to rotate to the unlocked state. The rotating locking member 2 pushes the door hook 200 to move a certain distance, causing the door 400 to deflect at a certain angle relative to the vertical direction. Under the action of gravity, the door 400 begins to flip downwards, and the speed of the door 400 gradually increases. By setting a buffer assembly between the door 400 and the housing 300, the opening speed of the door 400 can be limited, making the opening speed of the door 400 more gradual, which is beneficial to improving the service life of the cooking equipment 2000. In some specific embodiments, the buffer assembly can be a slow-opening hinge 7, a torsion spring, or other buffer structures; this invention does not limit this.

[0085] In some specific embodiments, the buffer assembly is a slow-opening hinge 7, which includes a body 71 and a hook 72 rotatable relative to the body 71. One of the body 71 and the hook 72 is mounted on the housing 300 and the other is mounted on the door 400.

[0086] When the rotating locking member 2 is rotated to the unlocked state, the door hook 200, pushed by the rotating locking member 2, causes the door body 400 to open by 5 to 10 degrees. The door body 400 begins to flip downward under the action of gravity. When the door body 400 flips to 35 to 55 degrees, the slow-opening hinge 7 begins to buffer the door body 400 to prevent the door body 400 from opening too quickly to the maximum opening angle.

[0087] Reference Figure 5 , Figure 6 and Figure 7 In some embodiments, the cooking device 2000 further includes a first micro switch 5, which is electrically connected to the cooking component to control the operating state of the cooking component. The rotation locking component 2 includes a first trigger 27. When the rotation locking component 2 is in the unlocked state, the first trigger 27 cooperates with the first micro switch 5 to at least de-energize the cooking component.

[0088] In this embodiment of the utility model, the first trigger 27 on the rotating locking member 2 controls the power on and off of the first micro switch 5. When the door 400 is opened, the rotating locking member 2 will inevitably rotate, and the first trigger 27 will rotate with the rotating locking member 2 to cooperate with the first micro switch 5 to de-energize the cooking component.

[0089] The above technical solution ensures that the cooking component is powered off when the door 400 is open, preventing the cooking component from working while the door 400 is open, thus avoiding harm to the user and improving the safety of the cooking equipment 2000.

[0090] In some embodiments, when the rotating locking member 2 is in the locked state, the first trigger member 27 cooperates with the first micro switch 5 to energize the cooking component.

[0091] When the rotating locking member 2 is in the locked state, the rotating locking member 2 locks the door hook 200 and the door body 400 is completely closed to place the opening. At this time, the first trigger member 27 cooperates with the first micro switch 5 to power on the cooking unit. The cooking unit will not affect the user when it is working, and the cooking unit can cook food as soon as it is powered on, ensuring the cooking effect of the cooking equipment 2000.

[0092] In some specific embodiments, the first microswitch 5 is configured as a normally open switch. In the locked state, the first trigger 27 abuts against the first microswitch 5 to close the first microswitch 5, thereby energizing the cooking appliance. In the unlocked state, the first trigger 27 moves away from the first microswitch 5 to open the first microswitch 5, thereby de-energizing the cooking appliance. In other embodiments, the first microswitch 5 can also be a normally closed switch. In the locked state, the first trigger 27 moves away from the first microswitch 5 to close the first microswitch 5, thereby energizing the cooking appliance. In the unlocked state, the first trigger 27 abuts against the first microswitch 5 to open the first microswitch 5, thereby de-energizing the cooking appliance.

[0093] In some embodiments, the cooking appliance 2000 further includes a second micro switch 6 for short-circuit protection, and the rotation locking member 2 includes a second trigger member 28 for triggering the second micro switch 6. The opening and closing states of the first micro switch 5 and the second micro switch 6 are opposite. The first micro switch 5 causes the second micro switch 6 to open to break the circuit when the cooking appliance is powered on.

[0094] With the above technical solution, when the door 400 is opened, the first micro switch 5 is opened to de-energize the cooking component. At this time, the second trigger 28 on the rotating locking component 2 cooperates with the second micro switch 6 to close the second micro switch 6 to short-circuit the circuit, forming short-circuit protection. The de-energization of the first micro switch 5 and the short-circuit protection of the second micro switch 6 form a dual protection, further improving the safety of the cooking equipment 2000.

[0095] In some specific embodiments, the second micro switch 6 is a normally closed switch. In the locked state, the second trigger 28 abuts against the second micro switch 6 to open the second micro switch 6, so that the cooking device can be powered on and work normally. In the unlocked state, the second trigger 28 moves away from the second micro switch 6 to close the second micro switch 6, forming a short circuit protection to ensure the safety of the cooking device 2000.

[0096] In other embodiments, the second micro switch 6 can also be a normally open switch. In the locked state, the second trigger 28 moves away from the second micro switch 6 to open the second micro switch 6, so that the cooking device can be powered on and work normally. In the unlocked state, the second trigger 28 abuts against the second micro switch 6 to close the second micro switch 6, forming a short circuit protection to ensure the safety of the cooking device 2000.

[0097] In some embodiments, the first microswitch 5 is configured as a normally open switch. In the locked state, the first trigger 27 abuts against the first microswitch 5 to close the first microswitch 5, thereby energizing the cooking appliance. In the unlocked state, the first trigger 27 moves away from the first microswitch 5 to open the first microswitch 5, thereby de-energizing the cooking appliance. The second microswitch 6 is a normally closed switch. In the locked state, the second trigger 28 abuts against the second microswitch 6 to open the second microswitch 6, allowing the cooking appliance to operate normally. In the unlocked state, the second trigger 28 moves away from the second microswitch 6 to close the second microswitch 6, forming short-circuit protection and ensuring the safety of the cooking device 2000.

[0098] The first micro switch 5 includes a first mating part 51 for cooperating with the first trigger 27, and the second micro switch 6 includes a second mating part 61 for cooperating with the second trigger 28. In the unlocked state, the distance between the second trigger 28 and the second mating part 61 is smaller than the distance between the first trigger 27 and the first mating part 51.

[0099] When the rotating locking member 2 rotates from the unlocked state to the locked state, the second trigger member 28 first stops with the second mating part 61 to open the second micro switch 6, and then the first trigger member 27 stops with the first mating part 51 to close the first micro switch 5, so that the cooking component is powered on.

[0100] When the rotating locking member 2 rotates from the locked state to the unlocked state, the first trigger member 27 first disengages from the first mating part 51 to open the first micro switch 5, thereby de-energizing the cooking component. Then, the second trigger member 28 disengages from the second mating part 61 to close the second micro switch 6, thus forming short-circuit protection.

[0101] Through the above technical solution, when the door 400 is closed and the opening is placed, during the rotation of the locking component toward the locked state, the second micro switch 6 is first opened to release the short circuit protection, and then the first micro switch 5 is closed, so that the cooking component can be powered on and work normally, ensuring the safety of the cooking equipment 2000.
