Cooking utensils

[0001] This application claims priority to Chinese patent application filed on December 12, 2024, with application number "2024230776612" and entitled "Microwave Oven", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of cooking utensil technology, and more specifically, to a cooking utensil. Background Technology

[0003] Currently, the traditional opening methods for cooking appliances in related technologies include mechanical button type, mechanical button sliding door type, and mechanical sliding door type. However, this traditional opening structure requires manual operation, has a low degree of automation, and poor linkage and reliability with the operation of household appliances.

[0004] Therefore, how to design a cooking appliance that can improve the level of automation has become an urgent problem to be solved.

[0005] Application content

[0006] This application aims to at least address the problem of low automation levels in cooking appliances.

[0007] Therefore, this application provides a cooking utensil.

[0008] In view of the above, this application proposes a cooking appliance, comprising: a housing having a receiving cavity; a door disposed on one side of the housing and movably connected to the housing for opening or closing the receiving cavity; a locking member disposed on the door or the housing, the locking member being capable of locking or unlocking the door and the housing, wherein when the door and the housing are locked, the door closes the receiving cavity, and when the door and the housing are unlocked, the door opens the receiving cavity; an electric drive mechanism connected to the housing, the electric drive mechanism being capable of driving the locking member to move, thereby unlocking the door and the housing; and an electronic control assembly disposed in the housing, the electronic control assembly including a circuit board and a door switch, the door switch being electrically connected to the circuit board, and the electric drive mechanism being electrically connected to the circuit board, wherein when the door switch is turned on, the circuit board controls the electric drive mechanism to drive the locking member to move, thereby unlocking the door and the housing to open the receiving cavity.

[0009] The cooking appliance provided in this application includes a housing, a door, a locking element, an electric drive mechanism, and an electronic control assembly. The locking element is located on the housing or door and is used to lock the door to the housing, closing the receiving cavity, or to unlock the door to the housing, opening the receiving cavity. The electric drive mechanism is located on the housing and can push the locking element to move, unlocking the door from the housing. The electronic control assembly includes a door switch. When the door switch is activated, the circuit board receives an opening signal and controls the electric drive mechanism to operate. The electric drive mechanism drives the locking element to move, unlocking the door from the housing and opening the receiving cavity, thus achieving an automatic door opening function, improving the automation level of opening the cooking appliance door, and making it easier for the user to open the door.

[0010] In some embodiments, the cooking appliance may optionally include: a cooking section disposed in the housing and electrically connected to a circuit board, the cooking section being used to heat food within the receiving cavity; and an interlocking assembly including an interlocking switch disposed in the housing and opposite to the electric drive mechanism and / or locking member; wherein, during the process of the electric drive mechanism driving the locking member to move, the electric drive mechanism and / or locking member can be linked to the interlocking switch to turn on or off, thereby de-energizing the cooking section and the electric drive mechanism.

[0011] In this embodiment, the cooking appliance also includes a cooking section and an interlock switch. The cooking section is used to cook the food inside the cavity. The interlock switch is arranged opposite to the electric drive mechanism and / or locking element so that when the electric drive mechanism drives the locking element to unlock, the movement of the electric drive mechanism and / or locking element causes the interlock switch to be linked. That is, when the electric drive mechanism drives the locking element to move, the interlock switch is braked or released, thereby de-energizing the electric drive mechanism and cooking section corresponding to the interlock switch, improving the safety performance when the door is open, and reliably preventing microwave leakage during microwave cooking.

[0012] In some embodiments, the interlocking switch may optionally include: a first micro switch disposed in the housing, which disconnects when the door is opened to de-energize the electric drive mechanism; and a second micro switch disposed in the housing, which disconnects when the door is opened to de-energize the cooking section.

[0013] In this embodiment, the interlocking switch includes a first micro switch and a second micro switch. When the door is opened to receive the cavity, the first micro switch is disconnected, causing the electric drive mechanism to lose power and preventing the electric drive mechanism from continuously operating and causing unnecessary power consumption when the door is open. The second micro switch is located in the housing. During the process of the door opening to receive the cavity, the action of the electric drive mechanism or the locking member causes the second micro switch to disconnect, thereby causing the cooking unit to lose power and preventing the cooking unit from operating when the door is open, which could cause burns to the user or microwave leakage.

[0014] In some embodiments, the interlocking switch may optionally include: a third micro switch, disposed in the housing, which disconnects when the door is opened to provide feedback on the opening status of the door to the circuit board; and a fourth micro switch, disposed in the housing between the cooking unit and the power supply, which disconnects when the door is opened to disconnect the cooking unit from the power supply.

[0015] In this embodiment, the micro switch further includes a third micro switch and a fourth micro switch. When the electric drive mechanism drives the locking member to move, causing the door to open the receiving cavity, the third micro switch is disconnected to feed back the information that the door is open to the circuit board, thereby achieving power failure protection and preventing the cooking unit or other electrical components from operating during the door opening process. Similarly, when the electric drive mechanism drives the locking member to move, causing the door to open the receiving cavity, the fourth micro switch is disconnected, breaking the circuit between the cooking unit and the power supply, improving the safety performance in the open state, and further ensuring the reliability of the cooking unit's disconnection in the event of the second micro switch failure.

[0016] In some embodiments, optionally, a first micro switch is disposed opposite to an electric drive mechanism, which can trigger the first micro switch; and / or when the door is closed, a second, third, and fourth micro switch are disposed opposite to a locking member, and when the electric drive mechanism drives the locking member to move, the locking member is linked to the second, third, and fourth micro switches.

[0017] In this embodiment, the first micro switch is disposed opposite to the electric drive mechanism. During the process of the electric drive mechanism driving the locking member to unlock, it can release the first micro switch, causing the first micro switch to disconnect, thereby de-energizing the electric drive mechanism and preventing the electric drive mechanism from continuously moving when the door is open. The triggering actions of the second, third, and fourth micro switches are realized through the locking member. Optionally, during the process of the electric drive mechanism driving the locking member to move, the locking member directly or indirectly releases the second, third, and fourth micro switches, causing them to disconnect, thereby realizing door status feedback and de-energizing the cooking unit.

[0018] In some embodiments, optionally, when the door closes the receiving cavity, along the height direction of the cooking appliance, a second micro switch is located at the top of the locking member and is in a conductive state, a third micro switch is located at the bottom of the locking member and is in a conductive state, and a fourth micro switch is located at the bottom of the locking member and is in a conductive state.

[0019] In this embodiment, when the door is closed and the receiving cavity is closed, along the height direction of the cooking appliance, the second micro switch is located at the top of the locking member, the third micro switch is located at the bottom of the locking member, and the fourth micro switch is located at the bottom of the locking member. Thus, when the locking member moves, the second, third, and fourth micro switches can be linked together to achieve the disconnection of the second, third, and fourth micro switches.

[0020] In some embodiments, the interlocking assembly may optionally further include: a first linkage arm rotatably disposed on the housing, wherein when the door is closed and the receiving cavity is closed, one end of the first linkage arm is located at the bottom of the locking member, and the other end of the first linkage arm contacts and activates the second micro switch; when the door is open and the receiving cavity is open, the first linkage arm rotates to release the second micro switch at the other end; and / or a second linkage arm rotatably disposed on the housing, wherein a third micro switch is located at the bottom of the second linkage arm, wherein when the door is closed and the receiving cavity is closed, the locking member presses against the top of the second linkage arm to contact the second linkage arm and activate the third micro switch; when the door is open and the receiving cavity is open, the second linkage arm rotates to release the third micro switch.

[0021] In this embodiment, the interlocking assembly further includes a first linkage arm and a second linkage arm. The locking member drives the second micro switch to operate via the first linkage arm, causing the second micro switch to open or close. The locking member also drives the third micro switch to operate via the second linkage arm, causing the third micro switch to open or close. This allows for more flexible placement of the second and third micro switches, preventing multiple interlocking switches from clustering around the locking member and causing unreliable triggering. Optionally, one end of the first linkage arm is positioned opposite the locking member, and the other end is positioned opposite the second micro switch. The first linkage arm can rotate relative to the housing, so that when the locking member moves, the first linkage arm can rotate, causing the other end of the first linkage arm to move relative to the second micro switch, releasing the second micro switch and thus disconnecting it, thereby cutting off the power to the cooking unit. The third micro switch is located at the bottom of the second linkage arm. When the door closes the receiving cavity, the locking member presses against the top of the second linkage arm so that the second linkage arm contacts the third micro switch, making the third micro switch conduct. Correspondingly, when the door opens the receiving cavity, the locking member leaves the second linkage arm, causing the second linkage arm to rotate, releasing the third micro switch, and thus making the third micro switch disconnect.

[0022] In some embodiments, the locking element optionally includes: a first hook body capable of locking or unlocking with the housing; a second hook body connected to the first hook body, capable of locking or unlocking with the housing, the first hook body and the second hook body being spaced apart along the height direction of the cooking appliance, a driving mechanism for driving the second hook body to move and causing the first hook body to move so that both the first hook body and the second hook body are unlocked from the housing; wherein, when the door is closed to receive the cavity, a fourth micro switch is located at the bottom of the first hook body, a second micro switch is located at the top of the second hook body, and a third micro switch is located at the bottom of the second hook body.

[0023] In this embodiment, the locking element includes a first hook and a second hook, which are connected to each other. When the electric drive mechanism drives the locking element to move, the electric drive mechanism also drives the second hook to move. Consequently, the first and second hooks move simultaneously through their connection, unlocking both the first and second hooks from the housing. Furthermore, the arrangement of the second, third, and fourth microswitches is such that the second microswitch is located at the top of the second hook, the third microswitch at the bottom of the second hook, and the fourth microswitch at the bottom of the first hook. This arrangement makes the second, third, and fourth microswitches more rational, allowing the movement of the first and second hooks to simultaneously trigger the actions of the second, third, and fourth microswitches.

[0024] In some embodiments, the interlocking assembly may optionally include: a bracket connected to the housing, wherein a locking element is capable of locking or unlocking the bracket, wherein a first micro switch, a fourth micro switch and an electric drive mechanism are located on one side of the bracket, and a second micro switch and a third micro switch are located on the other side of the bracket.

[0025] In this embodiment, the interlocking assembly also includes a bracket connected to the housing, and the locking element locks to the housing via the bracket. The first, second, third, and fourth microswitches are all mounted on the bracket, allowing the interlocking switches and bracket to form an assembly. When assembling the cooking appliance, the interlocking switches and bracket can be assembled first, and then installed on the housing, simplifying the assembly process and reducing assembly difficulty. For example, the first and fourth microswitches and the electric drive mechanism are located on one side of the bracket, while the second and third microswitches are located on the other side. This separate arrangement of the first, second, third, and fourth microswitches on both sides of the bracket fully utilizes the space on both sides and avoids the situation where the first, second, third, and fourth microswitches are piled up on one side of the bracket, resulting in insufficient movement space.

[0026] In some embodiments, the electric drive mechanism may optionally include: a drive motor mounted on a bracket; and a rotating part rotatably connected to the bracket. The drive motor is connected to the rotating part and is used to drive the rotating part to rotate, thereby pushing the locking member to move and triggering a first micro switch.

[0027] In this embodiment, the drive mechanism includes a drive motor and a rotating part. The drive motor is connected to the bracket, and the rotating part is rotatably connected to the bracket. When the door switch is on, the circuit board controls the drive motor to be powered on, so that the drive motor drives the rotating part to rotate, and then the rotating part drives the locking member to move, thereby unlocking the door and the box. At the same time, the rotating part can also directly trigger the first micro switch, so that the first micro switch is disconnected, and then the drive motor is powered off after opening the door.

[0028] In some embodiments, the rotating part may optionally include a cam structure.

[0029] In this embodiment, the rotating part includes a cam structure, which, when rotating, lifts the locking element by means of the cam structure, thereby unlocking the door from the box.

[0030] In some embodiments, the cam structure may optionally include: a wheel body rotatably connected to a bracket; and a plurality of convex arms spaced apart circumferentially along the wheel body, wherein at least one convex arm is used to push the locking member to move so as to unlock the locking member from the housing, and at least one convex arm is used to trigger a first micro switch.

[0031] In this embodiment, the cam structure includes a wheel and a convex arm. The wheel is rotatably mounted on the cabinet, and the convex arm is positioned around the wheel. When the wheel rotates, it drives the convex arm to rotate, which in turn drives the locking mechanism to move, unlocking the door and opening it. This effectively avoids the jamming or strenuous operation that can occur with traditional door opening methods, greatly improving the smoothness of the user experience. Simultaneously, the rotation of the convex arm actuates or releases a first microswitch. That is, the actuation and release of the convex arm and the first microswitch are linked, establishing a tight mechanical and electrical linkage mechanism. When the convex arm moves to a specific position, it can precisely control the state change of the first microswitch, thereby coordinating the start and stop of the drive motor. This ensures that the drive motor operates or stops at the appropriate time, achieving both automated and effective control of the door opening process and ensuring the synchronization and coordination between mechanical actions and electrical control of the entire system. This prevents malfunctions or safety hazards caused by improper coordination between the two, further enhancing the overall stability and safety of the microwave oven.

[0032] In some embodiments, optionally, a locking member is disposed on the door body and slidably connected to the door body. When the door switch is on, an electric drive mechanism drives the locking member to slide above the cooking appliance to unlock the door body from the cabinet; and / or the door switch includes a touch button or a mechanical button.

[0033] In this embodiment, the locking element is slidably connected to the door. When the door switch is on, the electric drive mechanism pushes the locking element upward, causing it to slide relative to the door. This separates the locking element from the locking structure on the cabinet, thus unlocking the door and opening the receiving cavity. The sliding connection method for moving the locking element is simple and requires less space, reducing the overall size of the cooking appliance. For example, the door switch may include a touch button to transmit an opening signal when the user touches it, or it may include a mechanical button to transmit an opening signal when the user presses or rotates the door switch.

[0034] In some embodiments, the cooking unit may optionally include at least one of a microwave generator, a heating element, and a hot air assembly.

[0035] In this embodiment, the cooking unit includes at least one of a microwave generator, a heating element, and a hot air assembly. When the cooking unit includes a microwave generator, microwave cooking can be achieved. When the cooking unit includes a heating element, a baking function can be achieved. When the cooking unit includes a hot air assembly, an air frying function can be achieved.

[0036] Alternatively, cooking appliances include microwave ovens, ovens, air fryers, microwave air fryers, etc.

[0037] In some embodiments, the housing may optionally include a front panel with a cooking opening communicating with a receiving cavity, an electronic control assembly located on the front panel, and an interlocking assembly connected to the front panel.

[0038] In this embodiment, both the electronic control component and the interlocking component are located on the front panel of the enclosure, making them close to the door for easy driving and control of the door.

[0039] In some embodiments, the cooking appliance may optionally include a baking tray, detachably disposed within the housing, for holding ingredients to be cooked.

[0040] In this embodiment, a removable baking tray can also be provided inside the cavity, so that the food can be placed on the baking tray for cooking.

[0041] Additional aspects and advantages of this application will become apparent in the following description or may be learned by practice of this application. Attached Figure Description

[0054] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0055] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0056] The cooking appliances proposed according to some embodiments of this application are described below with reference to Figures 1 to 10.

[0057] As shown in Figures 1, 2, 3, 5, 7, and 9, according to one embodiment of this application, a cooking appliance is provided, comprising: a housing 1 having a receiving cavity 10; a door 2 disposed on one side of the housing 1 and movably connected to the housing 1 for opening or closing the receiving cavity 10; and a locking member 3 disposed on the door 2 or the housing 1, the locking member 3 being capable of locking or unlocking the door 2 to the housing 1. When the door 2 is locked to the housing 1, the door 2 closes the receiving cavity 10; when the door 2 is unlocked to the housing 1, the door 2 opens or closes the receiving cavity 10. 2. Open the receiving cavity 10; Electric drive mechanism 4, connected to the housing 1, can drive the locking member 3 to move so that the door 2 is unlocked from the housing 1; Electric control component 5, located in the housing 1, includes a circuit board 50 and a door switch 51, the door switch 51 is electrically connected to the circuit board 50, and the electric drive mechanism 4 is electrically connected to the circuit board 50. When the door switch 51 is turned on, the circuit board 50 controls the electric drive mechanism 4 to drive the locking member 3 to move so that the door 2 is unlocked from the housing 1, thereby opening the receiving cavity 10.

[0058] The cooking appliance provided in this application includes a housing 1, a door 2, a locking element 3, an electric drive mechanism 4, and an electronic control assembly 5. The locking element 3 is located on either the housing 1 or the door 2, used to lock the door 2 to the housing 1, thereby closing the receiving cavity 10, or to unlock the door 2 from the housing 1, thereby opening the receiving cavity 10. The electric drive mechanism 4 is located on the housing 1 and can push the locking element 3 to move, thereby unlocking the door 2 from the housing 1. The electronic control assembly 5 includes a door switch 51. When the door switch 51 is turned on, the circuit board 50 receives an opening signal and controls the electric drive mechanism 4 to operate. The electric drive mechanism 4 drives the locking element 3 to move, thereby unlocking the door 2 from the housing 1 and opening the receiving cavity 10, thus realizing an automatic door opening function, improving the automation level of opening the cooking appliance door, and making it easier for the user to open the door.

[0059] Optionally, the door switch 51 being turned on includes the door switch 51 being pressed, or the door switch 51 being turned on via a wireless transmission function, for example, the cooking appliance receiving an operation command from the user to the door switch 51, causing the door switch 51 to be turned on.

[0060] For example, the locking element 3 is disposed on the door body 2 and can be connected to the box body 1 so that the door body 2 is locked to the box body 1, or the locking element 3 is disposed on the box body 1 and can be connected to the door body 2 so that the door body 2 is locked to the box body 1.

[0061] As shown in Figures 1, 5, 6, and 9, in some embodiments, the cooking appliance may optionally include: a cooking section 6, disposed in the housing 1 and electrically connected to the circuit board 50, the cooking section 6 being used to heat the food in the receiving cavity 10; and an interlocking assembly 7, the interlocking assembly 7 including an interlocking switch 70, the interlocking switch 70 being disposed in the housing 1 and opposite to the electric drive mechanism 4 and / or the locking member 3; wherein, during the process of the electric drive mechanism 4 driving the locking member 3 to move, the electric drive mechanism 4 and / or the locking member 3 can be linked to the interlocking switch 70, so that the interlocking switch 70 is turned on or off, and the cooking section 6 and the electric drive mechanism 4 are de-energized.

[0062] In this embodiment, the cooking appliance also includes a cooking section 6 and an interlock switch 70. The cooking section 6 is used to cook the food inside the cavity 10. The interlock switch 70 is disposed opposite to the electric drive mechanism 4 and / or the locking member 3. When the electric drive mechanism 4 drives the locking member 3 to unlock, the movement of the electric drive mechanism 4 and / or the locking member 3 causes the interlock switch 70 to be linked. That is, when the electric drive mechanism 4 drives the locking member 3 to move, the interlock switch 70 is braked or released, thereby de-energizing the electric drive mechanism 4 and the cooking section 6 corresponding to the interlock switch 70, improving the safety performance of the door 2 in the open state, and reliably preventing microwave leakage during microwave cooking.

[0063] It is understandable that during the process of the electric drive mechanism 4 driving the locking member 3 to move, the electric drive mechanism 4 and / or the locking member 3 can be linked to the interlock switch 70. That is, the electric drive mechanism 4 and / or the locking member 3 can directly or indirectly drive the interlock switch 70 to move, so that the interlock switch 70 is released or braked together. No additional drive structure is needed to realize the movement of the interlock switch 70, thereby reducing the use of parts and improving the space of the accommodating cavity 10, thereby increasing the cooking capacity of the food.

[0064] As shown in Figures 1, 2 and 3, in some embodiments, the interlocking switch 70 may optionally include: a first micro switch 702, disposed in the housing 1, which disconnects when the door 2 opens the receiving cavity 10 to de-energize the electric drive mechanism 4; and a second micro switch 704, disposed in the housing 1, which disconnects when the door 2 opens the receiving cavity 10 to de-energize the cooking section 6.

[0065] In this embodiment, the interlocking switch 70 includes a first micro switch 702 and a second micro switch 704. When the door 2 opens the receiving cavity 10, the first micro switch 702 is disconnected, causing the electric drive mechanism 4 to be de-energized, preventing the electric drive mechanism 4 from continuously operating and causing ineffective power consumption when the door 2 is open. The second micro switch 704 is located in the housing 1. During the process of the door 2 opening the receiving cavity 10, the action of the electric drive mechanism 4 or the locking member 3 causes the second micro switch 704 to be disconnected, thereby de-energizing the cooking unit 6 and preventing the cooking unit 6 from working when the door 2 is open, which could cause burns to the user or microwave leakage.

[0066] As shown in Figures 1, 3, 5, 6, and 7, in some embodiments, the interlocking switch 70 may optionally include: a third micro switch 706, located in the housing 1, which is disconnected when the door 2 opens the receiving cavity 10 to provide feedback on the opening status of the door 2 to the circuit board 50; and a fourth micro switch 708, located in the housing 1 between the cooking section 6 and the power supply, which is disconnected when the door 2 opens the receiving cavity 10 to disconnect the cooking section 6 from the power supply.

[0067] In this embodiment, the interlocking switch 70 further includes a third micro switch 706 and a fourth micro switch 708. When the electric drive mechanism 4 drives the locking member 3 to move, causing the door 2 to open the receiving cavity 10, the third micro switch 706 is disconnected to feed back the information that the door 2 is open to the circuit board 50, thereby achieving power failure protection and preventing the cooking unit 6 or other electrical components from operating during the opening of the door 2. Similarly, when the electric drive mechanism 4 drives the locking member 3 to move, causing the door 2 to open the receiving cavity 10, the fourth micro switch 708 is disconnected, disconnecting the circuit between the cooking unit 6 and the power supply, improving the safety performance in the open state, and further ensuring the reliability of the disconnection of the cooking unit 6 in the event of failure of the second micro switch 704.

[0068] In some embodiments, optionally, the first micro switch 702 is disposed opposite to the electric drive mechanism 4, and the electric drive mechanism 4 can trigger the first micro switch 702; and / or when the door 2 closes the box 1, the second micro switch 704, the third micro switch 706 and the fourth micro switch 708 are all disposed opposite to the locking member 3, and when the electric drive mechanism 4 drives the locking member 3 to move, the locking member 3 is linked to the second micro switch 704, the third micro switch 706 and the fourth micro switch 708.

[0069] In this embodiment, the first micro switch 702 is disposed opposite to the electric drive mechanism 4. During the process of the electric drive mechanism 4 driving the locking member 3 to unlock, the first micro switch 702 can be released, causing the first micro switch 702 to disconnect, thereby de-energizing the electric drive mechanism 4 and preventing the electric drive mechanism 4 from moving continuously when the door is open. The triggering action of the second micro switch 704, the third micro switch 706, and the fourth micro switch 708 is realized through the locking member 3. Optionally, during the process of the electric drive mechanism 4 driving the locking member 3 to move, the locking member 3 directly or indirectly releases the second micro switch 704, the third micro switch 706, and the fourth micro switch 708, causing the second micro switch 704, the third micro switch 706, and the fourth micro switch 708 to disconnect, realizing the status feedback of the door 2 and the de-energization of the cooking part 6.

[0070] In some embodiments, optionally, when the door 2 closes the receiving cavity 10, along the height direction H of the cooking appliance, the second micro switch 704 is located at the top of the locking member 3 and is in the on state, the third micro switch 706 is located at the bottom of the locking member 3 and is in the on state, and the fourth micro switch 708 is located at the bottom of the locking member 3 and is in the on state.

[0071] In this embodiment, when the door 2 closes the receiving cavity 10, along the height direction H of the cooking appliance, the second micro switch 704 is located at the top of the locking member 3, the third micro switch 706 is located at the bottom of the locking member 3, and the fourth micro switch 708 is located at the bottom of the locking member 3. Thus, when the locking member 3 moves, the second micro switch 704, the third micro switch 706, and the fourth micro switch 708 can be linked together to disconnect the second micro switch 704, the third micro switch 706, and the fourth micro switch 708.

[0072] Optionally, when the locking member 3 moves, it can directly drive the second micro switch 704, the third micro switch 706, and the fourth micro switch 708 to operate, causing the second micro switch 704, the third micro switch 706, and the fourth micro switch 708 to disconnect. Alternatively, it can be driven by other structures to operate the second micro switch 704, the third micro switch 706, and the fourth micro switch 708, causing the second micro switch 704, the third micro switch 706, and the fourth micro switch 708 to disconnect.

[0073] As shown in Figures 1 and 3, in some embodiments, the interlocking assembly 7 may optionally further include: a first linkage arm 72, rotatably disposed on the housing 1, wherein when the door 2 closes the receiving cavity 10, one end of the first linkage arm 72 is located at the bottom of the locking member 3, and the other end of the first linkage arm 72 contacts and activates the second micro switch 704; when the door 2 opens the receiving cavity 10, the first linkage arm 72 rotates to release the second micro switch 704; and / or a second linkage arm 74, rotatably disposed on the housing 1, wherein a third micro switch 706 is located at the bottom of the second linkage arm 74; when the door 2 closes the receiving cavity 10, the locking member 3 presses against the top of the second linkage arm 74 to contact the second linkage arm 74 with the third micro switch 706, and the third micro switch 706 is activated; when the door 2 opens the receiving cavity 10, the second linkage arm 74 rotates to release the third micro switch 706.

[0074] In this embodiment, the interlocking assembly 7 further includes a first linkage arm 72 and a second linkage arm 74. The locking member 3 drives the second micro switch 704 to actuate via the first linkage arm 72, causing the second micro switch 704 to open or close. The locking member 3 also drives the third micro switch 706 to actuate via the second linkage arm 74, causing the third micro switch 706 to open or close. This allows for more flexible placement of the second and third micro switches 704 and avoids the situation where multiple interlocking switches 70 are clustered around the locking member 3, leading to unreliable triggering. Optionally, one end of the first linkage arm 72 is positioned opposite the locking member 3, and the other end is positioned opposite the second micro switch 704. The first linkage arm 72 can rotate relative to the housing 1. When the locking member 3 moves, the first linkage arm 72 can rotate, causing the other end of the first linkage arm 72 to move relative to the second micro switch 704, thereby releasing the second micro switch 704 and disengaging it, thus de-energizing the cooking unit 6. The third micro switch 706 is located at the bottom of the second linkage arm 74. When the door 2 closes the receiving cavity 10, the locking member 3 is pressed against the top of the second linkage arm 74 so that the second linkage arm 74 contacts the third micro switch 706, making the third micro switch 706 conduct. Correspondingly, when the door 2 opens the receiving cavity 10, the locking member 3 leaves the second linkage arm 74, causing the second linkage arm 74 to rotate, releasing the third micro switch 706, and thus making the third micro switch 706 disconnect.

[0075] As shown in Figures 2 and 3, in some embodiments, optionally, the locking element 3 includes: a first hook 30, capable of locking or unlocking with the housing 1; a second hook 32, connected to the first hook 30, capable of locking or unlocking with the housing 1; the first hook 30 and the second hook 32 are spaced apart along the height direction H of the cooking appliance; a driving mechanism is used to drive the second hook 32 to move and drive the first hook 30 to move so that both the first hook 30 and the second hook 32 are unlocked from the housing 1; wherein, when the door 2 closes the receiving cavity 10, the fourth micro switch 708 is located at the bottom of the first hook 30, the second micro switch 704 is located at the top of the second hook 32, and the third micro switch 706 is located at the bottom of the second hook 32.

[0076] In this embodiment, the locking member 3 includes a first hook 30 and a second hook 32, which are connected. When the electric drive mechanism 4 drives the locking member 3 to move, the electric drive mechanism 4 also drives the second hook 32 to move. Consequently, the first hook 30 and the second hook 32 move simultaneously through their connection, unlocking both the first hook 30 and the second hook 32 from the housing 1. Simultaneously, in the arrangement of the second micro switch 704, the third micro switch 706, and the fourth micro switch 708, the second micro switch 704 is located at the top of the second hook 32, the third micro switch 706 is located at the bottom of the second hook 32, and the fourth micro switch 708 is located at the bottom of the first hook 30. This arrangement makes the second micro switch 704, the third micro switch 706, and the fourth micro switch 708 more rational, allowing the movement of the first hook 30 and the second hook 32 to simultaneously coordinate the actions of the second micro switch 704, the third micro switch 706, and the fourth micro switch 708.

[0077] It is understandable that, along the height direction H of the cooking utensil, the first hook 30 is located above the second hook 32, the fourth micro switch 708 is located at the bottom of the first hook 30, the second micro switch 704 is located at the top of the second hook 32, and the third micro switch 706 is located at the bottom of the second hook 32.

[0078] As shown in Figures 1, 2, 3 and 4, in some embodiments, the interlocking assembly 7 may optionally include: a bracket 76 connected to the housing 1, and a locking member 3 capable of locking or unlocking the bracket 76. The first micro switch 702, the fourth micro switch 708 and the electric drive mechanism 4 are located on one side of the bracket 76, and the second micro switch 704 and the third micro switch 706 are located on the other side of the bracket 76.

[0079] In this embodiment, the interlocking assembly 7 further includes a bracket 76, which is connected to the housing 1. The locking member 3 is locked to the housing 1 via the bracket 76. The first micro switch 702, the second micro switch 704, the third micro switch 706, and the fourth micro switch 708 are all mounted on the bracket 76, thus enabling the interlocking switch 70 and the bracket 76 to form an assembly. When assembling the cooking appliance, the interlocking switch 70 and the bracket 76 can be assembled first, and then installed on the housing 1, simplifying the assembly process and reducing assembly difficulty. For example, the first micro switch 702, the fourth micro switch 708 and the electric drive mechanism 4 are located on one side of the bracket 76, and the second micro switch 704 and the third micro switch 706 are located on the other side of the bracket 76. This arrangement of the first micro switch 702, the second micro switch 704, the third micro switch 706 and the fourth micro switch 708 on both sides of the bracket 76 makes full use of the space on both sides of the bracket 76 and avoids the situation where the first micro switch 702, the second micro switch 704, the third micro switch 706 and the fourth micro switch 708 are piled up on one side of the bracket 76, resulting in insufficient movement space.

[0080] For example, both the first linkage arm 72 and the second linkage arm 74 are rotatably mounted on the bracket 76.

[0081] As shown in Figures 1 and 8, in some embodiments, optionally, the electric drive mechanism 4 includes: a drive motor 40 mounted on a bracket 76; and a rotating part 42 rotatably connected to the bracket 76. The drive motor 40 is connected to the rotating part 42 and is used to drive the rotating part 42 to rotate, thereby pushing the locking member 3 to move and triggering the first micro switch 702.

[0082] In this embodiment, the drive mechanism includes a drive motor 40 and a rotating part 42. The drive motor 40 is connected to the bracket 76, and the rotating part 42 is rotatably connected to the bracket 76. When the door switch 51 is on, the circuit board 50 controls the drive motor 40 to be energized, so that the drive motor 40 drives the rotating part 42 to rotate, and then the rotating part 42 drives the locking member 3 to move, thereby unlocking the door 2 from the box 1. At the same time, the rotating part 42 can also directly trigger the first micro switch 702, so that the first micro switch 702 is disconnected, and then the drive motor 40 is de-energized after opening the door 2.

[0083] In some embodiments, the rotating part 42 may optionally include a cam structure 420.

[0084] In this embodiment, the rotating part 42 includes a cam structure 420, which, when rotating, lifts the locking member 3 by means of the cam structure 420, thereby unlocking the door 2 from the box 1.

[0085] As shown in Figure 1, in some embodiments, optionally, the cam structure 420 includes: a wheel body 422, rotatably connected to the bracket 76; and a plurality of convex arms 424, spaced apart circumferentially along the wheel body 422, wherein at least one convex arm 424 is used to push the locking member 3 to move so that the locking member 3 is unlocked from the housing 1, and at least one convex arm 424 is used to trigger the first micro switch 702.

[0086] In this embodiment, the cam structure 420 includes a wheel 422 and a convex arm 424. The wheel 422 is rotatably mounted on the housing 1, and the convex arm 424 is disposed around the wheel 422. When the wheel 422 rotates, it drives the convex arm 424 to rotate, which in turn drives the locking member 3 to move, thereby unlocking the door 2 from the housing 1 and opening the door 2. This effectively avoids the jamming or strenuous operation that may occur with traditional door opening methods, greatly improving the smoothness of the user experience. Meanwhile, when the convex arm 424 rotates, it can actuate or release the first micro switch 702. That is, the actuation and release of the convex arm 424 and the first micro switch 702 are linked, forming a tight mechanical and electrical linkage mechanism. When the convex arm 424 moves to a specific position, it can precisely control the state change of the first micro switch 702, thereby coordinating the start and stop of the drive motor 40 and ensuring that the drive motor 40 runs or stops at the appropriate time. This not only achieves effective automated control of the door 2 opening process, but also ensures the synchronization and coordination between the mechanical action and electrical control of the entire system, preventing malfunctions or safety hazards caused by improper coordination between the two, and further enhancing the overall stability and safety of the microwave oven.

[0087] In some embodiments, the number of protruding arms 424 may be multiple, and the multiple protruding arms 424 are arranged at circumferential intervals along the wheel body 422.

[0088] In some embodiments, the number of protruding arms 424 may optionally be four.

[0089] In some embodiments, the number of protruding arms 424 may be five.

[0090] In some embodiments, optionally, the locking member 3 is disposed on the door body 2 and the locking member 3 is slidably connected to the door body 2. When the door switch 51 is turned on, the electric drive mechanism 4 drives the locking member 3 to slide above the cooking appliance so that the door body 2 is unlocked from the cabinet 1; and / or the door switch 51 includes a touch button or a mechanical button.

[0091] In this embodiment, the locking member 3 is slidably connected to the door body 2. When the door switch 51 is on, the electric drive mechanism 4 pushes the locking member 3 upward, causing the locking member 3 to slide relative to the door body 2. This separates the locking member 3 from the locking structure on the housing 1, thus unlocking the door body 2 from the housing 1 and allowing the door body 2 to open the receiving cavity 10. The sliding connection method for moving the locking member 3 is simple and requires less space, which helps reduce the overall volume occupied by the cooking appliance. For example, the door switch 51 includes a touch button, which transmits an opening signal when the user touches the door switch 51; or the door switch 51 includes a mechanical button, which transmits an opening signal when the user presses or rotates the door switch 51.

[0092] In some embodiments, the cooking unit 6 may optionally include at least one of a microwave generator, a heating element, and a hot air assembly. And / or the housing 1 includes a front panel 14, which has a cooking opening 140 communicating with the receiving cavity 10. An electronic control assembly 5 is disposed on the front panel 14, and an interlocking assembly 7 is connected to the front panel 14.

[0093] In this embodiment, the cooking unit 6 includes at least one of a microwave generator, a heating element, and a hot air assembly. When the cooking unit 6 includes a microwave generator, microwave cooking can be achieved; when it includes a heating element, a baking function can be achieved; and when it includes a hot air assembly, an air frying function can be achieved. The electronic control component 5 and the interlocking component 7 are both located on the front panel 14 of the housing 1, placing them close to the door 2 for easy driving and control of the door 2.

[0094] Alternatively, cooking appliances include microwave ovens, ovens, air fryers, microwave air fryers, etc.

[0095] In some embodiments, the cooking appliance may optionally include a baking pan, which is detachably disposed within the housing 1 for holding the food to be cooked.

[0096] In this embodiment, a removable baking tray can also be provided in the receiving cavity 10, so that the food can be held in the baking tray for cooking.

[0097] Optionally, the housing 1 is provided with a raised rib 12, which allows the locking element 3 to engage with the raised rib 12, thereby achieving relative locking between the door 2 and the housing 1. The raised rib 12 not only effectively ensures the stability of the connection, but also has a simple structure and is easy to install.

[0098] Optionally, in some embodiments, the cooking appliance may further include: a plurality of sensors disposed in the housing 1 for detecting the temperature and humidity inside the housing 1.

[0099] In these embodiments, multiple sensors can also be installed inside the enclosure 1 to detect the temperature and humidity inside the enclosure 1. This arrangement, using multiple sensors to detect the temperature and humidity inside the enclosure 1, can effectively improve the cooking effect of the microwave oven during the baking process.

[0100] In some embodiments, the cooking appliance may optionally include an elastic member disposed between the housing 1 and the door 2. When the door switch 51 is turned on, the electric drive mechanism 4 drives the locking member 3 to move, thereby unlocking the door 2 from the housing 1, and the door 2 opens the receiving cavity 10, and the opening angle is further increased under the action of the elastic member.

[0101] In these embodiments, an elastic element can also be provided between the housing 1 and the door 2 to improve the ease of opening the door 2. When the cooking appliance door 2 is closed, the elastic element is compressed or stretched and stores a certain amount of elastic potential energy. Once the locking element 3 releases the door 2, the elastic potential energy stored in the elastic element is released and converted into power to drive the door 2 toward the open position. This allows the door 2 to automatically open to a certain angle.

[0102] Optionally, the electronic control assembly 5 also includes a control panel 52, a display panel 53, and a knob 54. The display panel 53 is located on the control panel 52, and the door switch 51 is located on the control panel 52. The control panel 52 has a control patch 520 and a touch patch 522. The door switch 51 is connected to the touch patch 522 and the control patch 520. The knob 54 is located on the control panel 52 and is connected to the circuit board 50 for controlling the operation of the cooking unit 6, such as adjusting the cooking time, cooking mode, and cooking power. The knob 54 includes a knob cover 540, a knob bracket 542, a knob sleeve 544, and a knob plate 546. The knob cover 540, knob bracket 542, knob sleeve 544, and knob plate 546 are connected by screws.

[0103] According to one embodiment of this application, a cooking appliance is proposed, comprising a control box assembly (e.g., an electronic control assembly 5), a door assembly (e.g., a door body 2), an electric interlock assembly (e.g., an interlock assembly 7), a cavity assembly (e.g., a housing 1), and an electric motor (e.g., an electric drive mechanism 4). When a user sends a signal, the information board (or structural component) of the control box assembly receives the operation signal, and the power board (e.g., a circuit board 50) supplies power to the electric motor. The door assembly includes a door hook (e.g., a locking element 3) that can slide up and down. The electric interlock assembly has a cam structure 420 with multiple convex arms 424. When the cam structure 420 rotates, the convex arms 424 move the locking element 3 upwards, and the rotation of the convex arms 424 contacts the first micro switch 702, controlling the electric motor to disconnect from power. The synchronous interlock lever A (first linkage arm 72) separates from the micro switch B (second micro switch 704), disconnecting the transformer and stopping power supply. When the cam rotates and the cam arm 424 moves the locking member 3 upward, the interlocking lever B (e.g., the second linkage arm 74) moves upward, disengaging the micro switch C (e.g., the third micro switch 706) and transmitting the door opening / closing information. During the process of the cam arm 424 moving the locking member 3 upward, the micro switch D (e.g., the fourth micro switch 708) separates from the locking member 3, disconnecting the main circuit power supply.

[0104] Work process:

[0105] Door opening: Pressing the door switch 51 of the control box assembly sends a signal to the circuit board 50. Upon receiving the signal, the circuit board 50 supplies power to the electric drive mechanism 4. The cam structure 420 on the motor rotates, and the convex arm 424 of the cam structure 420 moves the locking member 3 upward to release the obstruction. The cam release contacts the power-off switch at the motor position, and the synchronous lever A (first rotating arm) disconnects the micro switch B (second micro switch 704), short-circuiting the transformer terminals (ensuring no working output). During the upward movement of the locking member 3, the interlocking lever B (second rotating arm) moves upward, disengaging from the micro switch C (third micro switch 706), transmitting the door opening information to the power board. During the upward movement of the locking member 3 by the cam, the micro switch D (first micro switch 702) separates from the locking member 3, disconnecting the main circuit power supply.
