Description

[0001] Cooking utensils

[0002] Technical Field

[0003] This application relates to the field of small household appliance technology, and more specifically, to a cooking appliance.

[0004] Background Technology

[0005] In related technologies, an electric pressure cooker includes a pot body and a lid mounted on the pot body. During the cooking process, the lid needs to be stably connected to the pot body to ensure user safety and the stable pressure and temperature required for cooking.

[0006] In the aforementioned electric pressure cooker, a locking mechanism is installed between the pot body and the lid. The locking mechanism is a locking mechanism formed between the lid's locking cap, locking ring, or clamp and the pot body's insulation cover, inner pot, or load-bearing ring through the lid teeth and pot teeth.

[0007] In related technologies, a handle is installed on the lid to lock and unlock the locking mechanism, while an opening button controls the hook mechanism. This means that the user must operate the handle before pressing the opening button, making operation inconvenient.

[0008] For ease of operation, an electrically driven component, such as a motor, is used to lock and unlock the locking mechanism. An open-lid button is also provided to control the hook mechanism. This open-lid button only controls the hook mechanism and has a relatively simple function. When opening the lid is required, the motor first unlocks the locking mechanism, and then the user operates the open-lid button to control the hook mechanism to finally open the lid.

[0009] During the above operation, the user needs to wait for the motor-controlled locking mechanism to unlock before operating the hook mechanism, which makes the operation inconvenient.

[0010] Summary of the Invention

[0011] The main purpose of this application is to provide a cooking appliance that solves the problem of inconvenience for users in opening the lid in related technologies.

[0012] To achieve the above objectives, this application provides a cooking appliance, comprising: a pot body; a lid body, closably mounted on the pot body; a locking mechanism, movably mounted on the lid body, having a locked state that engages with the pot body and an unlocked state that engages with the pot body; a lid opening and closing mechanism, mounted on the lid body, including a transmission mechanism and an electric telescopic component, the electric telescopic component drivingly engaging with the transmission mechanism, the electric telescopic component driving the locking mechanism to switch from an unlocked state to a locked state via the transmission mechanism; and an operating component, movably mounted on the pot body and drivingly engaging with the transmission mechanism, the operating component driving the locking mechanism to switch from a locked state to an unlocked state via the transmission mechanism, and the operating component driving the lid body to open. Applying the technical solution of this application, the pot body and lid body have locking mechanisms, which are used to lock the locking mechanism to the pot body. In this embodiment, when the lid is closed, the electric telescopic component drives the locking mechanism to switch from an unlocked state to a locked state via a transmission mechanism. The electric telescopic component, in conjunction with the transmission mechanism, locks the locking mechanism to the pot body. When the lid is opened, the operating component, when triggered, drives the locking mechanism to switch from a locked state to an unlocked state via the transmission mechanism, completing the unlocking operation. Simultaneously, the operating component drives the lid to open. Therefore, in this application, the lid-closing operation can be performed electrically, simplifying the user's operation. The lid-opening operation can be achieved by the user operating the operating component, unlocking the locking mechanism from the pot body and opening the lid with a single operation. This effectively improves the convenience of the user's lid-opening operation. The technical solution of this embodiment effectively solves the problem of inconvenient lid-opening operation in related technologies.

[0013] Furthermore, the lid opening and closing mechanism also includes a position holding structure disposed between the top of the pot body and the bottom of the lid body. The operating component can cooperate with the position holding structure to engage the lid body onto the pot body or to detach the lid body from the pot body. When the position holding structure detaches the lid body from the pot body, the operating component can drive the transmission mechanism through the position holding structure, causing the transmission mechanism to switch the locking mechanism from a locked state to an unlocked state. The position holding structure allows the operating component to not only unlock the locking mechanism but also drive the lid body to open, making it easy for users to open the lid simply by operating the operating component, simplifying the operation steps and achieving one-button lid opening, which is very convenient.

[0014] Furthermore, the position-holding structure includes a locking platform and a movable hook. The locking platform is located on one of the pot body and the lid body, and the movable hook is movably located on the other of the lid body and the pot body. The movable hook has a locking position that engages with the locking platform and a releasing position that disengages from the locking platform. The operating component is driven by the movable hook, and the movable hook is driven by a transmission mechanism. The locking and disengaging design of the locking platform and the movable hook facilitates locking the lid body onto the pot body or opening it from the pot body. Moreover, the driving engagement of the operating component with the movable hook allows the user to manually unlock the locking mechanism and manually release the movable hook, simplifying the lid-opening operation.

[0015] Furthermore, the transmission mechanism includes a swinging component, which is oscillatingly mounted on the cover body and linked with the locking mechanism to allow the locking mechanism to move in either a first or second direction. The movable hook and the electrically operated telescopic component are both driven by the swinging component, wherein the second direction of movement is opposite to the first direction. The linkage between the swinging component and the locking mechanism, driven by the electrically operated telescopic component and the movable hook, enables the locking mechanism to move between the first and second directions. This design allows for easy switching of the locking mechanism's state through a simple swinging motion, improving operational convenience.

[0016] Furthermore, the swing member is provided with a hinge portion that engages with the cover body. The first end of the swing member is driven to engage with the locking mechanism. The contact position between the electric telescopic member and the swing member is located between the hinge portion and the first end of the swing member. The electric telescopic member and the movable hook are located on the same side of the swing member, with the hinge portion located in the middle of the swing member. The contact position between the movable hook and the swing member is located between the hinge portion and the second end of the swing member. The electric telescopic member is positioned between the hinge portion and the engagement position of the swing member and the locking mechanism. This allows the thrust of the electric telescopic member to be set relatively small, thereby reducing its cost. Moreover, the above structure facilitates the arrangement of the electric telescopic member and the movable hook on the cover body, enabling more rational use of space.

[0017] Furthermore, the transmission mechanism also includes a transmission slider, which is movably mounted on the cover body and works in conjunction with the locking mechanism to allow the locking mechanism to move in either a first or second direction. The movable hook and the electric telescopic component are both driven by the transmission slider, wherein the second direction of movement is opposite to the first direction. Driving the locking mechanism by controlling the movement of the transmission slider offers advantages such as simple structure and ease of control.

[0018] Furthermore, the transmission mechanism includes a swinging component and a transmission slider. The swinging component is swingably mounted on the cover body and engages with the locking mechanism to allow the locking mechanism to move in either a first or second direction. The transmission slider is movably mounted on the cover body and engages with the swinging component. The movable hook and the electric telescopic component both engage with the transmission slider. The engagement between the transmission slider and the swinging component ensures smooth transmission of the drive; that is, whether the electric telescopic component or the movable hook drives the transmission slider, the transmission slider always maintains a driving engagement with the swinging component to drive the locking mechanism to switch positions.

[0019] Furthermore, the transmission mechanism also includes a rack portion mounted on the transmission slider and a gear portion mounted on the oscillating member, with the rack portion and gear portion meshing with each other. Through the meshing between the gear portion and the rack portion, the movement of the transmission slider can be converted into the oscillation of the oscillating member, which has the advantages of simple structure and reliable transmission.

[0020] Furthermore, the opening and closing mechanism also includes a pushing component, which is slidably mounted on the cover body. When the movable hook moves, it pushes against the transmission mechanism. The aforementioned pushing component reduces the size of the movable hook, making it easier to transmit the movement stroke of the movable hook to the transmission mechanism.

[0021] Furthermore, the pot body is equipped with pot teeth that can lock and engage with the locking mechanism. When the position holding structure fastens the lid body onto the pot body, the locking mechanism is in the locked state, and the pot body is not pressed down, a gap is formed between the locking mechanism and the pot teeth. This gap ensures smooth engagement and replacement of the locking mechanism with the pot teeth during operation, preventing jamming and providing a better user experience.

[0022] Furthermore, the electric telescopic component is installed on the lid body along the front-back or left-right direction of the pot body. This arrangement of the electric telescopic component allows for flexible use of the space on the lid body, facilitating installation. Furthermore, the cooking appliance also includes an exhaust valve and an exhaust rod installed on the lid body. The exhaust valve has a blocking state and an exhaust state. The exhaust rod moves synchronously with the electric telescopic component and engages with the transmission mechanism. The exhaust rod pushes the transmission mechanism to switch the locking mechanism from an unlocked state to a locked state, and the exhaust rod drives the exhaust valve from a blocking state to an exhaust state. When the locking mechanism is in the locked state, the transmission mechanism remains stationary. When the electric telescopic component pushes the exhaust rod, the exhaust rod drives the exhaust valve from a blocking state to an exhaust state. The design of the exhaust valve and exhaust linkage not only ensures the locking and unlocking operation of the locking mechanism, but also synchronously controls the exhaust of the exhaust valve. This allows for a quick and safe reduction of the pressure inside the cooking appliance after cooking, further simplifying the opening operation and enhancing the safety and ease of operation of the equipment.

[0023] Furthermore, the cooking appliance also includes an inner pot lid located below the main body of the lid. The inner pot lid has a movable stop valve, and the main body of the lid has a stop hole corresponding to the stop valve. The cooking appliance also includes a stop slide plate on the main body of the lid, which engages with the stop valve. A transmission mechanism is linked to the stop slide plate. Through the stop valve engagement of the stop slide plate and the linkage between the transmission mechanism and the stop slide plate, the safety of the cooking appliance during high-pressure cooking is ensured. It also ensures that the locking mechanism can be easily unlocked and closed when needed, allowing for one-button opening, which is very convenient.

[0079] Detailed Implementation

[0080] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0081] In this application, the cooking appliance includes: a pot body 10, a lid body 20, a locking mechanism 30, a lid opening and closing mechanism 40, and an operating component 50. o The lid body 20 is closably mounted on the pot body 10. A locking mechanism 30 is movably mounted on the lid body 20, having a locked state (locked engagement with the pot body 10) and an unlocked state (unlocked engagement with the pot body 10). An opening / closing mechanism 40 is mounted on the lid body 20, including a transmission mechanism and an electric telescopic member 42. The electric telescopic member 42 is driven by the transmission mechanism and can drive the locking mechanism 30 from the unlocked state to the locked state via the transmission mechanism. An operating member 50 is movably mounted on the pot body 10 and driven by the transmission mechanism. The operating member 50 can drive the locking mechanism 30 from the locked state to the unlocked state via the transmission mechanism, and can also drive the lid body 20 to open.

[0082] Applying the technical solution of this application, the pot body and the lid body have locking mechanisms, which are used to lock the locking mechanism between the pot body and the lid body. In this embodiment, when the lid is closed, the electric telescopic component 42 can drive the locking mechanism 30 from the unlocked state to the locked state through the transmission mechanism. The electric telescopic component 42 and the transmission mechanism cooperate to achieve the locking between the locking mechanism 30 and the pot body 10. When the lid is opened, the operating component 50 is triggered and drives the locking mechanism 30 from the locked state to the unlocked state through the transmission mechanism, completing the unlocking operation. At the same time, the operating component 50 can drive the lid body 20 to open. Therefore, in this embodiment, the lid closing operation can be performed electrically, which simplifies the user's operation steps. The lid opening operation can be achieved by the user operating the operating component 50. With one operation, the lock between the locking mechanism 30 and the pot body 10 can be unlocked and the lid body 20 can be opened. This effectively improves the convenience of the user's lid opening operation, realizing one-button or one-step lid opening, which is very convenient. In this way, even in the event of a power outage, movement of the pot body, or unplugging the power supply, the lid can still be opened with a single operation of the operating component 50. The technical solution of this application effectively solves the problem in related technologies where the lid cannot be opened in the event of a power outage. Furthermore, neither the pot body 10 nor the lid body 20 of this application requires a handle structure for easy opening, resulting in a smoother outer surface for both the pot body 10 and the lid body 20, facilitating processing and reducing costs.

[0083] In this application, the lid opening and closing mechanism 40 also includes a position holding structure disposed between the top of the pot body 10 and the bottom of the lid body 20. The operating member 50 can cooperate with the position holding structure to engage or disengage the lid body 20 from the pot body. When the position holding structure disengages the lid body 20 from the pot body, the operating member 50 can drive the transmission mechanism through the position holding structure, thereby causing the transmission mechanism to switch the locking mechanism 30 from the locked state to the unlocked state. The position holding structure allows the operating member 50 to not only unlock the locking mechanism 30 but also drive the lid body 20 to open, making it easy for users to open the lid simply by operating the operating member 50, simplifying the operation steps and achieving one-button opening, which is very convenient.

[0084] In this application, the position holding structure includes a locking platform 11 and a movable hook 43. In one embodiment, the locking platform 11 is disposed on the pot body 10, and the movable hook 43 is movably disposed on the pot body 10. The movable hook 43 has a snap-fit ​​position that engages with the locking platform 11 and a release position that disengages from the locking platform 11. The operating member 50 drives the movable hook 43, and the movable hook 43 drives the transmission mechanism. The snap-fit ​​or release design of the locking platform 11 and the movable hook 43 facilitates the locking of the lid body 20 onto the pot body 10 or its opening from the pot body 10. Furthermore, the driving engagement of the operating member 50 with the movable hook 43 allows the user to manually unlock the locking mechanism 30 and manually release the movable hook 43, simplifying the lid opening operation.

[0085] In another embodiment, the latching part 11 is disposed on the cover body 20, and the movable latch 43 is movably disposed on the cover body 20.

[0086] In this application, the transmission mechanism includes a swing member 41, which is swingably mounted on the cover body 20 and linked with the locking mechanism 30 to allow the locking mechanism 30 to move in a first or second direction. The movable hook 43 and the electric telescopic member 42 are both driven by the swing member 41, wherein the second direction of movement is opposite to the first direction. The linkage between the swing member 41 and the locking mechanism 30, driven by the electric telescopic member 42 and the movable hook 43, allows the locking mechanism 30 to move between the first and second directions. This design achieves state switching of the locking mechanism 30 through a simple swinging motion, improving operational convenience.

[0087] In this application, the swing member 41 is provided with a hinge portion 411 that engages with the cover body 20. The first end of the swing member 41 is driven to engage with the locking mechanism 30. The contact position between the electric telescopic member 42 and the swing member 41 is located between the hinge portion 411 and the first end of the swing member 41. The electric telescopic member 42 and the movable hook 43 are located on the same side of the swing member 41. The hinge portion 411 is located in the middle of the swing member 41, and the contact position between the movable hook 43 and the swing member 41 is located between the hinge portion 411 and the second end of the swing member 41. The electric telescopic member 42 is located between the hinge portion 411 and the engagement position of the swing member 41 and the locking mechanism 30. This allows the thrust of the electric telescopic member 42 to be set relatively small, thereby reducing the cost of the electric telescopic member 42. Furthermore, the above structure also facilitates the arrangement of the electric telescopic component 42 and the movable hook 43 on the cover body 20, enabling more rational use of space.

[0088] In this application, the transmission mechanism further includes a transmission slider 46, which is movably mounted on the cover body 20 and engages with the locking mechanism 30 to allow the locking mechanism 30 to move in either a first or second direction. The movable hook 43 and the electric telescopic member 42 are both driven by the transmission slider 46, wherein the second direction of movement is opposite to the first direction. Driving the locking mechanism 30 by controlling the movement of the transmission slider 46 offers advantages such as simple structure and ease of control. Furthermore, the engagement of the transmission slider 46 with the electric telescopic member 42 and the movable hook 43 allows for the disconnection of the driving force; that is, after the electric telescopic member 42 retracts its drive, it will not pull the transmission slider 46 back; similarly, after the movable hook 43 resets its drive, it will not pull the transmission slider 46 back.

[0089] In this application, the transmission mechanism includes a swing member 41 and a transmission slider 46. The swing member 41 is swingably mounted on the cover body 20 and is linked with the locking mechanism 30 to allow the locking mechanism 30 to move in a first or second direction. The transmission slider 46 is movably mounted on the cover body 20 and is driven by the swing member 41. The movable hook 43 and the electric telescopic member 42 are both driven by the transmission slider 46. The cooperation between the transmission slider 46 and the swing member 41 ensures smooth transmission of the drive. That is, whether the electric telescopic member 42 drives the transmission slider 46 or the movable hook 43 drives the transmission slider 46, the transmission slider 46 can always maintain a driving cooperation with the swing member 41 to drive the locking mechanism 30 to switch positions.

[0090] In this application, the transmission mechanism further includes a rack portion 461 disposed on the transmission slider 46 and a gear portion 413 disposed on the swing member 41, wherein the rack portion 461 and the gear portion 413 mesh with each other. Through the meshing between the gear portion 413 and the rack portion 461, the movement of the transmission slider 46 can be converted into the swing of the swing member 41, which has the advantages of simple structure and reliable transmission.

[0091] In this application, the opening and closing mechanism 40 also includes a pusher 47, which is slidably disposed on the cover body 20. When the movable hook 43 is in motion, it can push the transmission mechanism through the pusher 47. The aforementioned pusher 47 reduces the size of the movable hook 43, making it easier to transmit the travel of the movable hook 43 to the transmission mechanism.

[0092] In this application, the pot body is provided with pot teeth that can lock and engage with the locking mechanism 30. When the position holding structure fastens the lid body 20 onto the pot body, the locking mechanism 30 is in a locked state, and the pot body 10 is in an unpressurized state, a gap is formed between the locking mechanism 30 and the pot teeth. This gap allows the locking mechanism 30 to smoothly engage and disengage with the pot teeth during operation, preventing jamming and improving the user's tactile experience. It should be noted that the aforementioned "unpressurized state" refers to the check valve 71 being in the lowered position and the check slide 22 not being opened.

[0093] In this application, the electric telescopic component 42 is disposed on the lid body 20 along the front-back direction or the left-right direction of the pot body 10. The above-mentioned arrangement of the electric telescopic component 42 can flexibly utilize the space on the lid body and facilitates installation.

[0094] In this application, the cooking appliance also includes an exhaust valve 25 and an exhaust rod 60 disposed on the lid body 20. The exhaust valve 25 has a blocking state and an exhaust state. The exhaust rod 60 moves synchronously with the electric telescopic member 42 and cooperates with the transmission mechanism to push and push. The exhaust rod 60 pushes the transmission mechanism to move, so that the locking mechanism 30 switches from the unlocked state to the locked state, and the exhaust rod 60 drives the exhaust valve 25 to switch from the blocking state to the exhaust state. When the locking mechanism 30 is in the locked state, the transmission mechanism remains stationary. When the electric telescopic member 42 pushes the exhaust rod 60, the exhaust rod 60 drives the exhaust valve 25 to switch from the blocking state to the exhaust state. The design of the exhaust valve 25 and the exhaust linkage 60 not only ensures the locking and unlocking operation of the locking mechanism 30, but also synchronously controls the exhaust of the exhaust valve 25. This allows for a quick and safe reduction of the pressure inside the cooking appliance after cooking, further simplifying the opening operation and enhancing the safety and ease of operation of the equipment.

[0095] In this application, the cooking appliance also includes an inner pot lid 70 disposed below the lid body 20. The inner pot lid 70 is provided with a movable stop valve 71. The lid body 20 is provided with a stop hole corresponding to the stop valve 71. The cooking appliance also includes a stop slide plate 22 disposed on the lid body 20. The stop slide plate 22 engages with the stop valve 71, and the transmission mechanism is linked to the stop slide plate 22. Through the stop engagement of the stop slide plate 22 and the stop valve 71, and the linkage between the transmission mechanism and the stop slide plate 22, the safety of the cooking appliance during high-pressure cooking is ensured. It also ensures that the locking mechanism 30 can be easily unlocked via the operating component 50 when needed, achieving one-button opening, which is very convenient.

[0096] The cooking appliance in this application is a pressure cooker, but it can also be a rice cooker, slow cooker, stir-fry machine, food processor, or other appliances with other functions.

[0097] In this application, the cooking appliance is described in detail in the following four embodiments:

[0098] Example 1 of the cooking utensil is shown in Figures 1 to 13, as detailed below:

[0099] Example 1 of the cooking appliance includes: a pot body 10, a lid body 20, a locking mechanism 30, a lid opening and closing mechanism 40, and an operating component 50. The pot body 10 is provided with a latching part 11; the lid body 20 is closably disposed on the pot body 10; the locking mechanism 30 is movably disposed on the lid body 20, and the locking mechanism 30 has a locked state that locks into the pot body 10 and an unlocked state that unlocks into the pot body 10; the opening and closing lid mechanism 40 is disposed on the lid body 20, and the opening and closing lid mechanism 40 includes a transmission mechanism, an electric telescopic member 42, and a movable hook 43. The movable hook 43 is movably disposed on the lid body 20 and has a snap-fit ​​position that engages with the latching part 11 and a release position that disengages from the latching part 11. Both the electric telescopic member 42 and the movable hook 43 are driven by the transmission mechanism. The electric telescopic member 42 can drive the locking mechanism 30 to switch from the unlocked state to the locked state through the transmission mechanism. When the movable hook 43 switches from the snap-fit ​​position to the release position, the movable hook 43... The transmission mechanism drives the locking mechanism 30 to switch from the locked state to the unlocked state; the operating element 50 is movably set on the lid body 20 or the pot body 10 and drives the movable hook 43 to cooperate. When the operating element 50 is triggered, the operating element 50 drives the movable hook 43 to switch from the latching position to the unlocking position.

[0100] According to the technical solution of Embodiment 1, the cooking appliance includes a pot body 10 and a lid body 20. The pot body 10 is provided with a fastening platform 11, and the lid body 20 is movably provided with a movable hook 43. The movable hook 43 can switch between a locking position that engages with the fastening platform 11 and a unlocking position that disengages from the fastening platform 11, thereby realizing the engagement or disengagement between the lid body 20 and the pot body 10. The lid body 20 is also provided with a locking mechanism 30, which can switch between a locked state that engages with the pot body 10 and an unlocked state that disengages from the pot body 10, thereby realizing the engagement or disengagement between the lid body 20 and the pot body 10. When the lid is closed, the movable hook 43 and the locking platform 11 automatically engage. Then, the electric telescopic component 42 drives the locking mechanism 30 from the unlocked state to the locked state via a transmission mechanism, thus achieving a double lock between the lid body 20 and the pot body 10. When the lid is opened, the user can operate the operating component 50 to drive the movable hook 43 from the engaged position to the disengaged position. During this process, the movable hook 43 also drives the locking mechanism 30 from the locked position to the unlocked position via a transmission mechanism, thus achieving a double unlock between the lid body 20 and the pot body 10. In the above process, when closing the lid, the locking mechanism 30 is locked primarily by electric drive through the electric telescopic component 42, simplifying the user's operation; when opening the lid, the movable hook 43 and the locking mechanism 30 are unlocked simply by manually driving the operating component 50. The user only needs to perform one operation, which has the advantage of simple operation. In the event of a power outage during cooking, the user can open the lid using the operating component 50 to prevent food from spoiling inside the cooking cavity. Therefore, the technical solution of Embodiment 1 effectively solves the problem of difficulty in opening cooking appliances during power outages in related technologies.

[0101] It should be noted that the aforementioned "automatic engagement of the movable hook 43 and the latching platform 11" is achieved through the mating inclined surface between them and the first reset member 45. The first reset member 45 applies a reset force to the movable hook 43 so that it remains in the engaged position when no external force is applied. During the user's downward pressure on the cover body 20, the movable hook 43 overcomes the force of the first reset member 45 under the action of the mating inclined surface and switches from the engaged position to the unengaged position. After the hook portion 432 of the movable hook 43 passes the latching platform 11, the movable hook 43 returns to the engaged position under the action of the first reset member 45.

[0102] As shown in Figures 1 to 5, the electric telescopic component 42 is a solenoid valve. When the valve stem of the solenoid valve extends, it pushes against the transmission mechanism. The solenoid valve includes a valve body and a lever. When the solenoid valve is turned on, the valve stem extends to push against the transmission mechanism. After the valve stem completes the pushing action, it retracts, so that the valve stem will not obstruct the movement of the transmission mechanism during subsequent manual opening of the cover.

[0103] As shown in Figures 1 to 5, the transmission mechanism includes a transmission slider 46 movably mounted on the cover body 20. The electric telescopic member 42 can push the transmission slider 46 to move along a first direction, and the movable hook 43 can push the transmission slider 46 to move along a second direction opposite to the first direction. Driving the locking mechanism 30 by controlling the movement of the transmission slider 46 along either the first or second direction offers advantages such as simple structure and ease of control. Furthermore, the interaction between the transmission slider 46, the electric telescopic member 42, and the movable hook 43 allows for the disconnection of the driving force. That is, after the electric telescopic member 42 completes its drive to retract the transmission slider 46, it will not pull the transmission slider 46 back; similarly, after the movable hook 43 completes its drive to reset the transmission slider 46, it will not pull the transmission slider 46 back. Specifically, as shown in Figures 2 and 4, in Embodiment 1, the first direction refers to forward movement, and the second direction refers to backward movement. In this context, "front" and "back" refer to the side closer to the user and the side farther away from the user during the user's use, respectively.

[0104] As shown in Figures 1 to 5, the transmission mechanism also includes a swinging member 41 disposed between the transmission slider 46 and the locking mechanism 30. When the transmission slider 46 moves along the first direction, it can drive the swinging member 41 to swing along the third direction, thereby driving the locking mechanism 30 to switch from the unlocked state to the locked state. When the transmission slider 46 moves along the second direction, it can drive the swinging member 41 to swing along the fourth direction opposite to the third direction, thereby driving the locking mechanism 30 to switch from the locked state to the unlocked state. The cooperation between the transmission slider 46 and the swinging member 41 can ensure the smooth transmission of the drive. That is, whether the electric telescopic member 42 drives the transmission slider 46 or the movable hook 43 drives the transmission slider 46, the transmission slider 46 can always maintain a driving cooperation with the swinging member 41 to drive the locking mechanism 30 to switch positions.

[0105] It should be noted that the "third direction" mentioned above refers to the counterclockwise direction in Figures 2 to 5, and the "fourth direction" mentioned above refers to the clockwise direction in Figures 2 to 5.

[0106] Specifically, as shown in Figure 1, the locking mechanism 30 is a locking ring structure located below the lid body 20. The locking ring structure is provided with locking teeth to engage with the pot teeth on the pot body 10. Of course, in the embodiment not shown in the figure, the locking mechanism can also be a clamp structure.

[0107] As shown in Figure 1, the main body 10 of the pot includes an outer shell 14, a middle plate 13 disposed above the outer shell 14, and a base 15 disposed below the outer shell 14. The inner pot 12 is disposed inside the shell structure formed by the middle plate 13, the outer shell 14, and the base 15. The inner pot 12 is provided with pot teeth. When the locking mechanism 30 is in the locked state, the locking teeth on the locking ring structure are aligned with the pot teeth and located below the pot teeth. When the locking mechanism 30 is in the unlocked state, the pot teeth on the locking ring structure are misaligned with the pot teeth, allowing the lid body 20 to move upward relative to the main body 10 of the pot.

[0108] As shown in Figures 3, 5, and 8, the first end of the swing member 41 is provided with a linkage groove 414, and the locking mechanism 30 is provided with a linkage post 31, which passes through the linkage groove 414. The linkage groove 414 is a long groove structure. When the swing member 41 swings, the linkage post 31 and the linkage groove 414 cooperate to drive the linkage post 31 to swing in an arc, thereby causing the electric locking mechanism 30 to rotate and switch between the locked and unlocked states. The above-mentioned linkage structure has the advantages of simple structure and reliable transmission.

[0109] As shown in Figures 3, 5, 7, and 8, the second end of the swing member 41 is provided with a gear part 413, and the transmission slider 46 is provided with a rack part 461 that meshes with the gear part 413. At the center of the gear part 413, a hinge part 411 is provided that engages with the cover body 20. Through the meshing between the gear part 413 and the rack part 461, the movement of the transmission slider 46 can be converted into the swing of the swing member 41, which has the advantages of simple structure and reliable transmission. Specifically, as shown in Figures 1 and 13, the hinge part 411 is a hinge hole, and a connecting post 16 is provided on the cover body 20. The connecting post 16 passes through the hinge part 411, allowing the swing member 41 to swing around the connecting post 16 to drive the locking mechanism 30 to switch states.

[0110] As shown in Figures 1, 3, 5, and 7, the transmission slider 46 serves as the transmission frame, and the electric telescopic component 42 is disposed within the transmission frame. The electric telescopic component 42 can push against the rear surface of the front frame wall of the transmission frame, and the movable hook 43 is disposed on the front side of the transmission frame and can push against the front surface of the front frame wall of the transmission frame. The transmission slider 46 serves as the transmission frame, and the electric telescopic component 42 is disposed within the transmission frame. This design ensures that the transmission slider 46 has sufficient length to achieve a sufficient mating dimension with the swing component 41, while reducing the space occupied by the lid body 20. The dimension of the transmission frame along the front-rear direction of the cooking appliance is larger than the dimension of the electric telescopic component 42 along the front-rear direction of the cooking appliance, allowing the transmission frame to move relative to the electric telescopic component 42 in the front-rear direction.

[0111] As shown in Figures 1, 3, and 7, the electric telescopic component 42 is installed at the mounting portion 17 on the cover body 20. Multiple elastic locking arms are provided at the mounting portion 17, and the electric telescopic component 42 is fixed to the cover body 20 via these elastic locking arms. The transmission frame is sleeved around the outer periphery of the multiple elastic locking arms and guides and engages with the outer surface of the elastic locking arms.

[0112] As shown in Figures 1 and 7, the cooking appliance also includes an inner pot lid 70 located below the lid body 20. A floating stop valve 71 is mounted on the inner pot lid 70. The lid body 20 has a stop valve hole through which the stop valve 71 passes. The cooking appliance also includes a stop valve slide plate 22 mounted on the lid body 20 and moving synchronously with the transmission slider 46. When the stop valve 71 floats upward, it engages with the stop valve slide plate 22. When pressure is applied to the cooking cavity, the stop valve 71 floats upward under the pressure, and at this time, the stop valve 71 engages with the stop valve slide plate 22, thus restricting the movement of the stop valve slide plate 22 and consequently restricting the movement of the transmission slider 46 that moves synchronously with the stop valve slide plate 22. This prevents the user from opening the lid, ensuring safety.

[0113] As shown in Figures 1 and 7, when the check valve 71 floats upward, it is located behind the check slide plate 22 and engages with it to restrict the rearward movement of the check slide plate 22 and the transmission slider 46. The check slide plate 22 has a mating post, and the side of the transmission slider 46 has a second connecting groove 462. The mating post passes through the second connecting groove 462, allowing the check slide plate 22 and the transmission slider 46 to move synchronously.

[0114] As shown in Figures 1 to 5 and Figure 9, the movable hook 43 includes a body portion 431 movably disposed on the cover body 20 and a hook portion 432 disposed at one end of the body portion 431 and extending downward out of the cover body 20. The hook portion 432 can engage with the fastening platform portion 11. The movable hook 43 is movably disposed on the cover body 20 via the body portion 431, and has the advantages of simple structure and reliable movement.

[0115] As shown in Figures 1 and 13, the lid body 20 is provided with a clearance opening 24 for the hook portion 432 to extend downwards, allowing the hook portion 432 to extend out of the lid body 20 to engage with the latching platform portion 11 provided on the pot body 10. As shown in Figures 1, 6, and 10, the lid opening and closing mechanism also includes a locking seat 44 provided on the lid body 20. The locking seat 44 and the body portion 431 are nested together to guide the movement of the body portion 431. The first reset member 45 is a spring structure provided between the locking seat 44 and the hook portion 432. The first reset member 45 applies a forward force to the hook portion 432 to keep the hook portion 432 in a hooked engagement state with the latching platform portion 11.

[0116] In Embodiment 1, the locking seat 44 is also a movable component. The locking seat 44 is provided with a first hook portion, and the inner pot lid 70 is provided with a second hook portion that engages with the hook of the first hook portion, allowing the inner pot lid 70 to be detachably installed below the lid body 20. The first reset component 45 applies a rearward force to the locking seat 44, keeping it in the position where the first hook portion and the second hook portion are engaged, ensuring the secure fixation of the inner pot lid 70. When the inner pot lid 70 needs to be removed, the user pushes the locking seat 44 forward through the portion of the locking seat 44 extending downwards from the lid body 20, causing the first hook portion to separate from the second hook portion. At this point, the user can remove the inner pot lid 70.

[0117] The locking seat 44 and the movable hook 43 serve to guide each other: when the inner pot lid 70 is to be removed, the movable hook 43 remains stationary under the action of the first reset member 45, and the movable hook 43 guides the movement of the locking seat 44; when the lid is to be opened, the locking seat 44 remains stationary under the action of the first reset member 45, and the locking seat 44 guides the movement of the movable hook 43.

[0118] To ensure the smooth and stable movement of the locking seat 44 and the movable hook 43, a guiding structure (e.g., guide post, guide plate, etc.) can be provided on the lid body 20. An upper limit can also be provided for the locking seat 44 and the movable hook 43 to prevent the locking seat 44 from moving upwards due to an upward force when it is engaged with the inner pot lid 70, and to prevent the movable hook 43 from moving upwards due to an upward force when it is engaged with the latching platform 11.

[0119] As shown in Figures 1, 2 and 4, the cooking utensil also includes a cover 23 that covers the lid body 20, and the cover can shield the various components installed on the lid body 20.

[0120] As shown in Figures 1 and 6, the operating element 50 is movably mounted on the cooker body 10. The cooking appliance also includes a lever 80 disposed between the operating element 50 and the movable hook 43. When the operating element 50 is triggered, it drives the lever 80 to swing, thereby causing the movable hook 43 to switch from a engaged position to an unengaged position. The lever 80 can transmit driving force, so that the driving force applied by the user to the operating element 50 can be transmitted to the movable hook 43 on the cooker body 20.

[0121] Specifically, as shown in Figures 1 and 6, the operating element 50 is an operating button. An opening 141 is provided on the outer casing 14, and the operating button is mounted on the outer casing 14 via an operating element mounting base 51 located at the opening 141. A third reset element 52 is provided between the operating button and the operating element mounting base 51. The third reset element 52 applies a forward reset force to the operating button, so that the operating button can reset after the user's pressing force on the operating button disappears, facilitating the user's next pressing operation. Specifically, the third reset element 52 is a spring structure. As shown in Figures 1, 6, and 11, the lever element 80 includes a pivot part 81 and a driving part 82. The lever element 80 is swayably connected to the pot body 10 via the pivot part 81, and the driving part 82 is driven to engage with the movable hook 43. The lever element 80 is swayably connected to the pot body 10 via the pivot part, which has the advantages of simple structure and reliable movement.

[0122] As shown in Figures 6 and 14, the middle plate 13 is provided with a clearance hole 131 for the drive part 82 to extend upward, so that the drive part 82 can extend out of the pot body 10 to engage with the movable hook 43. Of course, in an embodiment not shown in the figures, the hook part of the movable hook can also extend into the interior of the pot body through the clearance hole to engage with the drive part.

[0123] As shown in Figures 1, 6, and 11, the pivot 81 is located at the lower end of the lever 80, the drive 82 is located at the upper end of the lever 80, and the operating member 50 engages with the middle of the lever 80. This arrangement positions the lever 80 and the operating member 50 between the swing center of the lever 80 and the engagement position between the lever 80 and the movable hook 43. This amplifies the stroke of the user's action on the operating member 50; that is, a shorter distance driven by the user to move the operating member 50 can cause the movable hook 43 to move a relatively large distance.

[0124] As shown in Figures 1 and 12, the main body 10 of the pot also includes a lever mounting base 83 connected below the middle plate 13. The pivot part 81 is a pivot shaft structure. The lever mounting base 83 is provided with a pivot hole, and the pivot shaft passes through the pivot hole to realize the lever 80 being swayably mounted on the lever mounting base 83. A second reset member 84 is provided between the middle plate 13 and the lever 80. The second reset member 84 applies a forward force to the lever 80 so that the lever 80 remains in a position where it does not drive the movable hook 43 when no external force is applied, thereby ensuring that the movable hook 43 can be smoothly engaged with the latching part 11. The second reset member 84 is a spring structure.

[0125] As shown in Figures 6 and 9, the lower end of the movable hook 43 is provided with a downwardly extending drive engagement edge 435°. Since the lever 80 is a swinging component, the drive unit 82 will generate a downward displacement during the process of driving the movable hook 43 to move. The drive engagement edge 435 extends downward and has a certain vertical dimension. During the process of driving the movable hook 43, the drive unit 82 can always maintain a mating engagement state with the drive engagement edge 435.

[0126] The movement of each component during the opening and closing of the lid is explained below with reference to the accompanying drawings:

[0127] Figures 2 and 3 show schematic diagrams of the structure with the lid body 20 fastened to the pot body 10 and the locking mechanism 30 in the unlocked state. At this time, the movable hook 43 is fastened to the fastening platform 11, and the movable hook 43 and the transmission slider 46 are spaced apart in the front-back direction, and the swing member 41 is located at the extreme position of counterclockwise rotation.

[0128] In order to switch the locking mechanism 30 from the unlocked state to the locked state, the electric telescopic member 42 pushes the transmission slider 46 forward (that is, the lower right in Figure 3). The transmission slider 46 drives the swing member 41 to swing clockwise in Figure 3. When the swing member 41 swings to its limit position, it drives the locking mechanism 30 to switch to the locked state.

[0129] Figures 4 and 5 show schematic diagrams of the structure in which the lid body 20 is fastened to the pot body 10 and the locking mechanism 30 is in a locked state. At this time, the movable hook 43 is fastened to the fastening platform 11, the valve stem of the electric telescopic member 42 and the transmission slider 46 are spaced apart in the front-to-back direction, and the swing member 41 is located at the extreme position of clockwise rotation. To switch the movable hook 43 from the engaged position to the disengaged position and the locking mechanism 30 from the locked state to the unlocked state, the user presses the operating component 50. The operating component 50 pushes the lever component 80, causing the lever component 80 to swing counterclockwise as shown in Figure 6. During the swing, the lever component 80 pushes the movable hook 43 backward (to the left in Figure 6), causing the movable hook 43 to separate from the latching platform 11, thus switching the movable hook 43 to the disengaged position. As the movable hook 43 moves backward, it pushes the transmission slider 46, causing the transmission slider 46 to move backward synchronously (to the upper left in Figure 5). The transmission slider 46 drives the swinging component 41 to swing counterclockwise as shown in Figure 5. When the swinging component 41 swings to its limit position, it drives the locking mechanism 30 to switch to the unlocked position.

[0130] Example 2 of the cooking utensil, as shown in Figures 15 to 27, is as follows:

[0131] Figure 15 shows an exploded structural schematic diagram of an embodiment of the cooking appliance according to this application; Figure 16 shows a partial cross-sectional view of the cooking appliance of Figure 15.

[0132] As shown in Figures 15 to 27, the cooking appliance of Embodiment 2 includes: a pot body 10, a lid body 20, a locking mechanism 30, a lid opening and closing mechanism 40, and an operating component 50. oThe pot body 10 is provided with a latching section 11; the lid body 20 is closably mounted on the pot body 10; the locking mechanism 30 is movably mounted on the lid body 20 and has a locked state for locking the pot body 10 and an unlocked state for unlocking the pot body 10; the opening and closing lid mechanism 40 includes a swing member 41, an electric telescopic member 42, and a movable hook 43. The swing member 41 is swingably mounted on the lid body 20 and is linked with the locking mechanism 30. The electric telescopic member 42 is mounted on the lid body 20 and can drive the swing member 41 to swing in a first direction, so that the swing member 41 drives the locking mechanism 30 to switch from the unlocked state to the locked state. The movable hook 43 is movably mounted on the lid body and has a snap-fit ​​position that cooperates with the latching section 11 and a release position that separates from the latching section 11; the operating member 50 is movably mounted on either the pot body 10 or the lid body 20. When the operating element 50 is triggered, it can drive the movable hook 43 to switch from the latching position to the unlocking position, and the movable hook 43 drives the swinging element 41 to swing in the second direction, so that the swinging element 41 drives the locking mechanism 30 to switch from the locked state to the unlocked state, wherein the first direction and the second direction are opposite.

[0133] Applying the technical solution of Embodiment 2, the pot body 10 and the lid body 20 have two locking mechanisms: the first is the locking between the latching platform 11 and the movable hook 43, and the second is the locking between the locking mechanism 30 and the pot body 10. In this application, the lid opening and closing mechanism 40 includes a swinging member 41, an electric telescopic member 42, and a movable hook 43. The swinging member 41 is swingably disposed on the lid body 20 and is linked with the locking mechanism 30 to drive the locking mechanism 30 to switch between an unlocked state and a locked state. When the lid is closed, the locking mechanism 11 and the movable hook 43 automatically lock together (a first reset member 45 on the lid body 20 applies a reset force to the movable hook 43; during the closing process, the locking mechanism 11 first presses against the movable hook 43, causing the movable hook 43 to retract; after passing the locking mechanism 11, the movable hook 43 resets and engages with the locking mechanism 11). An electric telescopic member 42 is mounted on the lid body 20 and drives the swing member 41 to swing in a first direction, causing the swing member 41 to switch the locking mechanism 30 from the unlocked state to the locked state. The electric telescopic member 42, in conjunction with the swing member 41, enables the locking mechanism 30 to lock with the pot body 10. When the lid is opened, the operating member 50 is triggered, driving the movable hook 43 to switch from the engaged position to the unengaged position, completing the first type of unlocking operation. Simultaneously, the movable hook 43 drives the swinging member 41 to swing in a second direction opposite to the first direction, so that the swinging member 41 drives the locking mechanism 30 to switch from the locked state to the unlocked state, completing the unlocking operation of the second type of lock. Therefore, in the solution of Embodiment 2, the lid closing operation can be performed electrically, which simplifies the user's operation steps. The lid opening operation can be achieved by the user operating the operating member 50, that is, it can be completed manually. In this way, even in the event of a power outage, the lid can still be opened by operating the operating member 50. The technical solution of Embodiment 2 effectively solves the problem in the related art that the lid opening operation cannot be achieved in the event of a power outage.

[0134] In Embodiment 2, the first direction is clockwise and the second direction is counterclockwise. Of course, the first direction can also be counterclockwise and the second direction clockwise.

[0135] As shown in Figures 15 to 27, in Embodiment 2, the electric telescopic component 42 is a solenoid valve, and the valve stem of the solenoid valve engages with the swing component 41. The solenoid valve has a simple structure, good structural stability, and low cost. The solenoid valve includes a valve body and a valve stem. When the solenoid valve is energized, the valve stem extends and retracts intermittently. The extended valve stem pushes the swing component 41 to swing. Of course, the electric telescopic component 42 can also be other structures, such as an electric actuator or a cylinder, as long as it can achieve the function of pushing the swing component 41 to swing. In Embodiment 2, after the valve stem pushes the swing component 41 to swing, it automatically returns to the retracted position (the solenoid valve includes a return spring that drives the valve stem). This structure ensures that when the locking mechanism 30 is in the locked state, there is a gap between the swing component 41 and the valve stem. When the cover is opened, the valve stem will not contact the swinging component 41 when the operating component 50 drives the swinging component 41 to swing. As a result, the required driving force is smaller, which can reduce the operating force of the user and improve the user experience.

[0136] As shown in Figures 15 to 27, the swing member 41 is provided with a hinge portion 411 that engages with the cover body 20. The first end of the swing member 41 is driven to engage with the locking mechanism 30. The contact position between the electric telescopic member 42 and the swing member 41 is located between the hinge portion 411 and the first end of the swing member 41. The electric telescopic member 42 is located between the hinge portion 411 and the engagement position of the swing member 41 and the locking mechanism 30. This allows the thrust of the electric telescopic member 42 to be set relatively small, thereby reducing the cost of the electric telescopic member 42. A connecting post 16 is provided on the cover body 20. The hinge portion 411 is a hinge hole, which is fitted onto the connecting post 16 to achieve the hinge connection between the swing member 41 and the cover body 20. In the second embodiment, the vertical axis of the connecting post 16 is located at the center of the cover body 20.

[0137] As shown in Figures 15 to 27, the locking mechanism 30 includes a locking ring and a cover tooth disposed at the bottom of the locking ring. The pot body 10 includes an inner pot 12, and a pot tooth is provided at the opening of the inner pot 12. When the cover tooth and the pot tooth are aligned, the locking mechanism 30 is in a locked state; when the cover tooth and the pot tooth are misaligned, the locking mechanism 30 is in an unlocked state. The pot body 10 also includes a middle plate 13, an outer shell 14, and a base 15. The mounting plate 11 is disposed on the middle plate 13, and the inner pot 12 is located inside the outer shell 14.

[0138] As shown in Figures 15 to 27, the electric telescopic component 42 and the movable hook 43 are located on the same side of the swing component 41, the connecting part 411 is located in the middle of the swing component 41, and the contact position between the movable hook 43 and the swing component 41 is located between the connecting part 411 and the second end of the swing component 41. This structure facilitates the arrangement of the electric telescopic component 42 and the movable hook 43 on the cover body 20, allowing for more rational use of space. Alternatively, the electric telescopic component 42 and the movable hook 43 can be located on both sides of the swing component 41. In embodiment two, a clearance opening is provided on the cover body 20, and the movable hook 43 extends downwards from the clearance opening. The cover body 20 is also referred to as a liner, and a face cover 23 is also provided above the cover body 20.

[0139] As shown in Figures 15 to 27, the movable hook 43 includes a body part 431 and a hook part 432. The body part 431 is slidably disposed on the lid body 20 along the front-rear direction and cooperates with the swing member 41 in a pushing manner. The above structure is beneficial to improving the movement stability of the movable hook 43. In order to ensure that the movable hook 43 moves according to a preset trajectory, a guide structure can be provided between the lid body 20 and the movable hook 43 to ensure that the movable hook 43 moves according to the preset trajectory. For example, a guide post can be provided on the lid body 20, and a guide groove can be provided on the movable hook 43. The guide post passes through the guide groove to guide the movable hook 43. A locking seat 44 can be provided on the lid body 20. A guide cylinder is provided on the locking seat 44, and the guide post passes through the guide cylinder. The locking seat 44 is movably disposed and can limit the inner pot lid 70. When the inner pot lid 70 needs to be removed for cleaning, simply move the locking seat 44 to unlock the inner pot lid 70.

[0140] As shown in Figures 15 to 27, the main body 431 has a center line L extending along the sliding direction of the main body 431, which intersects the rotation axis of the swing member 41. The movable hook 43 also includes a pusher 433 disposed on one side of the main body 431, through which the main body 431 engages with the swing member 41. This structure can improve the smoothness of movement while simplifying the structure and avoid jamming between moving parts.

[0141] As shown in Figures 15 to 27, the cooking appliance also includes an exhaust valve 25 and an exhaust rod 60 disposed on the lid body 20. The exhaust valve 25 has a blocking state and an exhaust state. The exhaust rod 60 is disposed between the electric telescopic member 42 and the exhaust valve 25 and moves synchronously with the electric telescopic member 42. When the locking mechanism 30 is in the unlocked state, when the electric telescopic member 42 pushes the exhaust rod 60, the exhaust rod 60 pushes the swing member 41 to swing, so that the swing member 41 drives the locking mechanism 30 to switch from the unlocked state to the locked state, and the exhaust rod 60 drives the exhaust valve 25 to switch from the blocking state to the exhaust state. When the locking mechanism 30 is in the locked state, the swing member 41 remains stationary, and when the electric telescopic member 42 pushes the exhaust rod 60, the exhaust rod 60 drives the exhaust valve 25 to switch from the blocking state to the exhaust state. The aforementioned exhaust linkage 60 allows the electric telescopic component 42 to simultaneously engage the locking mechanism 30 and exhaust the exhaust valve 25, thus simplifying the overall structure and effectively reducing the cost of cooking appliances.

[0142] As shown in Figures 15 to 27, the exhaust linkage 60 includes a main rod 61, a push rod 62 disposed at the first end of the main rod 61, and a linkage head 63 disposed at the second end of the main rod 61. The main rod 61 is located above the swing member 41. The push rod 62 cooperates with the exhaust valve 25, and the linkage head 63 cooperates with the electric telescopic member 42. The distance between the push rod 62 and the linkage head 63 is greater than the width of the swing member 41. Because the distance between the push rod 62 and the linkage head 63 is greater than the width of the swing member 41, when the locking mechanism 30 is in the locked state, the swing member 41 remains stationary, and the exhaust linkage 60 moves toward the exhaust valve 25 to drive the exhaust valve 25 to switch from the blocking state to the exhaust state.

[0143] As shown in Figures 15 to 27, a valve cover 21 is provided on the lid body 20, covering the exhaust valve 25. The valve cover 21 has an exhaust port 211 and a through hole, and a sealing element 26 is provided at the through hole. The sealing element 26 has a mounting recess, and one end of the exhaust rod 60 passes through the mounting recess and cooperates with the exhaust valve 25. The sealing element 26 can apply a restoring force to the exhaust rod 60 toward the electric telescopic member 42. On the one hand, the sealing element 26 ensures the sealing of the valve cover 21, so that the gas in the cooking cavity of the pot body 10 will not be discharged from the through hole to the lid body 20. On the other hand, the sealing element 26 can provide a restoring force to the exhaust rod 60, keeping it in its initial position away from the exhaust valve 25. The sealing element 26 is made of an elastic material, such as rubber or silicone.

[0144] To improve the safety of the cooking appliance, as shown in Figures 15 to 27, in Embodiment 2, the cooking appliance further includes an inner pot lid 70 located below the lid body 20. The inner pot lid 70 is equipped with a movable stop valve 71. The lid body 20 has a stop hole corresponding to the stop valve 71. The cooking appliance also includes a stop slide plate 22 on the lid body 20, which engages with the stop valve 71. A swing member 41 is linked to the stop slide plate 22. The swing member 41 can move the stop slide plate 22, realizing the upward pressure stop function of the cooking appliance. The aforementioned stop valve 71 prevents the lid body 20 from opening when pressed upwards in the cooking cavity, ensuring safety during use.

[0145] As shown in Figures 15 to 27, one of the swing member 41 and the stop-opening slide plate 22 is provided with a linkage post 221, and the other is provided with a first connecting groove 412. The linkage post 221 passes through the first connecting groove 412. The above-mentioned linkage post 221 and first connecting groove 412 have simple structures and are easy to implement.

[0146] In the second embodiment, the operating component 50 is a button structure, the outer shell 14 is provided with an opening 141, the operating component mounting base 51 is provided at the opening 141, and the button structure is provided on the operating component mounting base 51.

[0147] As shown in Figures 15 to 27, the operating component 50 is movably mounted on the pot body 10. The cooking appliance also includes a lever component 80, which includes a pivot part 81 pivotally connected to the pot body 10 and a driving part 82 that drives the movable hook 43. The driving part 82 can drive the movable hook 43 from the engaged position to the disengaged position, and the operating component 50 can drive the lever component 80 to swing. The operating component 50 drives the movement of the movable hook 43 through the lever component 80, making the setting position of the movable hook 43 more flexible and the movement of the movable hook 43 smoother. The cooking appliance also includes a lever mounting seat 83 disposed inside the pot body 10, and the lever component 80 is mounted on the lever mounting seat 83. A second reset component 84 is also disposed between the lever component 80 and the pot body 10.

[0148] As shown in Figures 15 to 27, the operating member 50 is located between the pivot part 81 and the drive part 82. This structure allows the user to push the movable hook 43 with a small pushing force, improving the user experience.

[0149] As shown in Figures 15 to 27, in Embodiment 2, when assembling the movable hook 43 and the locking seat 44, the two are first assembled together, and a first reset component 45 (preferably a reset spring) is placed between them. These three components are then installed together on the cover body 20 and fixed by a fixing post. As shown in Figures 15 to 27, the top of the lever mounting seat 83 is connected to the middle plate 13, and the electric telescopic component 42 is installed in the mounting part 17 on the cover body 20 and fastened by a snap fastener. A linkage hole is provided at the first end of the swing component 41, which connects to the steel column of the locking mechanism 30. A first connecting groove 412 is provided at the second end of the swing component 41, which fits onto the linkage post 221 of the stop-opening slide plate 22. After installation, the electric telescopic component 42 pushes the linkage head 63 forward, which in turn pushes the swing component 41 to rotate the cover tooth to the engaged position. Simultaneously, the swing component 41 moves the stop-opening slide plate 22 forward to unlock the stop-opening valve. After the electric telescopic component 42 completes its operation, it returns to its original position. The exhaust rod 60, under the action of the sealing component 26, also moves backward, resetting and separating from the swing component. The swing component remains in its original position without external force. At this time, the electric telescopic component 42 only moves the exhaust rod 60 backward during startup and returns to its original position together after startup. When the exhaust rod 60 moves backward, the push rod 62 pushes the pressure limiting valve to move and exhaust air; after resetting, the push rod 62 cannot push the pressure limiting valve, thus sealing the pressure limiting valve. In the engaged position, the push top 433 of the movable hook 43 abuts against the side of the swing component. When the operating component (such as the cover opening button) is pressed, the push top 433 pushes the swing component 41 to rotate and drives the locking mechanism 30 to switch states.

[0150] When it is necessary to open the cover, press the operating part 50. The driving part 82 of the lever part 80 pushes the movable hook 43 and disengages it from the fastening surface of the fastening platform part 11. At the same time, during the disengagement process, the movable hook 43 pushes the top 433 against the side of the swing member, causing the swing member 41 to rotate. Simultaneously, the swing member 41 drives the anti-opening slide plate 22 to move together. Then, the swing member 41 drives the locking mechanism 30 to rotate and disengage to the open position, and the cover is opened.

[0151] When the lid is closed, the movable hook 43 engages with the locking surface of the locking platform 11 first, and the locking mechanism 30 does not engage with the locking teeth on the inner pot 12. If cooking is required, simply select the function on the lid, and the electric telescopic component 42 will activate, pushing the exhaust rod 60 to rotate the swing component. This technical solution features a simple structure and manufacturing process, stability and reliability, ease of production, and low cost. It also offers advantages such as easier operation and reduced user error.

[0152] Example 3 of the cooking utensil is shown in Figures 28 to 44, and is detailed below:

[0153] As shown in Figures 28 to 44, the third embodiment of the cooking appliance includes: a pot body 10, a lid body 20, a locking mechanism 30, a lid opening and closing mechanism 40, and an operating component 50. The lid body 20 is closably mounted on the pot body 10, and has a latching portion 11. A locking mechanism 30 is movably mounted on the lid body 20 and has a locked state for locking the pot body 10 and an unlocked state for unlocking the pot body 10. The lid opening and closing mechanism 40 includes a transmission mechanism and a movable hook 43. The transmission mechanism is movably mounted on the lid body 20 and is linked to the locking mechanism 30 to switch the locking mechanism 30 between a locked state and an unlocked state. The transmission mechanism moves in a first direction to switch the locking mechanism 30 from an unlocked state to a locked state. The movable hook 43 is movably mounted on the pot body 10 and has a snap-fit ​​position that engages with the latching portion 11 and a release position that separates from the latching portion 11. An operating member 50 is movably mounted on the pot body 10, and when triggered, it drives the movable hook 43. The latch 43 moves from the latching position to the unlocking position, and the movable hook 43 drives the transmission mechanism to move in the second direction, so that the transmission mechanism drives the locking mechanism 30 to switch from the locked state to the unlocked state, wherein the first direction and the second direction are opposite.

[0154] Applying the technical solution of Embodiment 3, the pot body 10 and the lid body 20 have two locking mechanisms: the first is the locking between the latching part 11 and the movable hook 43, and the second is the locking between the locking mechanism 30 and the pot body 10. In Embodiment 3, the lid opening and closing mechanism 40 includes a transmission mechanism and a movable hook 43. The transmission mechanism is movably mounted on the lid body 20 and linked with the locking mechanism 30 to drive the locking mechanism 30 to switch between an unlocked state and a locked state. When the lid is closed, the latching part 11 and the movable hook 43 can automatically lock together. The transmission mechanism moves in a first direction to drive the locking mechanism to switch from an unlocked state to a locked state. The transmission mechanism can achieve the locking between the locking mechanism 30 and the pot body 10. When the lid is opened, the operating member 50 is triggered, which can drive the movable hook 43 to switch from a latched position to an unlocked position, completing the unlocking operation of the first type of lock. Simultaneously, the movable hook 43 drives the transmission mechanism to move in a second direction opposite to the first direction, causing the transmission mechanism to switch the locking mechanism from the locked state to the unlocked state, completing the second type of locking unlocking operation. Therefore, in the solution of Embodiment 3, the lid opening operation can be achieved by the user operating the operating component 50, and the locking between the clasp and the movable hook, as well as the locking mechanism and the pot body, can be unlocked simultaneously with a single operation. This effectively improves the convenience of the user's lid opening operation. The technical solution of Embodiment 3 effectively solves the problem of inconvenient lid opening operation for users in related technologies.

[0155] As shown in Figures 28 to 44, the opening and closing mechanism 40 also includes an electrically operated telescopic component 42. The electrically operated telescopic component 42 is mounted on the cover body 20 and can drive the transmission mechanism to move in a first direction, causing the transmission mechanism to switch the locking mechanism 30 from an unlocked state to a locked state. The electrically operated telescopic component 42 cooperates with the transmission mechanism in a pushing motion. The inclusion of the electrically operated telescopic component 42 allows the closing operation to be performed electrically, thus simplifying the user's operation.

[0156] Preferably, the electric telescopic component 42 is a solenoid valve, and the valve stem of the solenoid valve is engaged with the transmission mechanism. The solenoid valve has a simple structure, good structural stability, and low cost. The solenoid valve includes a valve body and a valve stem. When the solenoid valve is energized, the valve stem extends and retracts intermittently. The extension of the valve stem can drive the transmission mechanism. Of course, the electric telescopic component 42 can also be other structures, such as electric push rods, cylinders, etc., as long as they can realize the function of pushing the transmission mechanism. In embodiment three, after the valve stem pushes the transmission mechanism, it will automatically return to the retracted position. The solenoid valve includes a return spring that drives the valve stem. The above structure ensures that when the locking mechanism 30 is in the locked state, there is a gap between the transmission mechanism and the valve stem. When the cover is opened, when the operating component 50 drives the transmission mechanism, the valve stem will not contact the transmission mechanism, thus requiring less driving force, thereby reducing the user's operating force and improving the user experience. The electric telescopic component 42 is installed in the mounting part 17 on the cover body 20 and is fastened by a buckle.

[0157] As shown in Figures 28 to 44, the opening and closing mechanism 40 also includes a pushing member 47. The pushing member 47 is slidably disposed on the cover body 20 along the front-rear direction. When the movable hook 43 is active, it can push the transmission mechanism through the pushing member 47. The arrangement of the pushing member 47 reduces the size of the movable hook 43, making it easier to transmit the active stroke of the movable hook 43 to the transmission mechanism. A first reset member 45 is disposed between the pushing member 47 and the cover body 20.

[0158] As shown in Figures 28 to 44, the locking mechanism 30 includes a locking ring and a cover tooth disposed at the bottom of the locking ring. The pot body 10 includes an inner pot 12, and a pot tooth is provided at the opening of the inner pot 12. When the cover tooth and the pot tooth are correspondingly arranged, the locking mechanism 30 is in a locked state; when the cover tooth and the pot tooth are misaligned, the locking mechanism 30 is in an unlocked state. The pot body 10 also includes a middle plate 13, an outer shell 14, and a base 15. The fastening platform 11 is disposed on the middle plate 13, and the inner pot 12 is located inside the outer shell 14. As shown in Figures 28 to 44, in Embodiment 3, the lid body 20 is provided with a clearance opening 24. The top of the movable hook 43 extends upward through the clearance opening 24 into the lid body 20, and the pusher 47 is disposed on the rear side of the movable hook 43. The aforementioned clearance opening 24 is used to avoid the movable hook 43 and the pusher 47, and the above structure makes the structural layout of the cooking appliance more reasonable. Accordingly, a clearance hole 131 is provided on the middle plate 13 of the pot body 10. When the top of the movable hook 43 extends upward, it first passes through the clearance hole 131 and then through the clearance opening 24 to enter the lid body 20.

[0159] As shown in Figures 28 to 44, a locking seat 44 can be provided on the lid body 20. A guide cylinder is provided on the locking seat 44, which is used to fit within the fixing post of the lid body 20. The locking seat 44 is movably provided and can limit the inner pot lid 70. When the inner pot lid 70 needs to be removed for cleaning, the inner pot lid 70 can be unlocked by moving the locking seat 44.

[0160] As shown in Figures 28 to 44, the movable hook 43 includes a body portion 431 and a hook portion 432. The body portion 431 is rotatably mounted on the pot body 10, and the hook portion 432 is located at the top of the body portion 431. The movable hook 43 also includes a pivot portion 434 mounted on the body portion 431. This structure facilitates the installation of the movable hook 43 and improves the engagement stability between the movable hook 43 and the mounting plate. The pivot portion 434 is located at the bottom of the body portion 431. This structure allows the user to push the movable hook 43 with a small pushing force, improving the user experience.

[0161] As shown in Figures 28 to 44, the cooking appliance also includes a hook mounting base 85 disposed within the pot body 10, and a movable hook 43 is mounted on the hook mounting base 85. A second resetting member 84 is also disposed between the movable hook 43 and the pot body 10. Alternatively, the main body can be movably disposed on the pot body 10 along the front-rear direction of the cooking appliance.

[0162] In Embodiment 3, as shown in Figures 28 to 44, the transmission mechanism includes a transmission slider 46 and a swing member 41 linked to the transmission slider 46. The electric telescopic member 42 drives the transmission slider 46 to move in a first direction, causing the swing member 41 to swing upwards in a third direction, thus causing the swing member 41 to switch the locking mechanism 30 from an unlocked state to a locked state. The movable hook 43 drives the transmission slider 46 to move in a second direction, causing the swing member 41 to swing in a fourth direction, thus causing the swing member 41 to switch the locking mechanism 30 from a locked state to an unlocked state. The third and fourth directions are opposite. The linkage between the transmission slider 46 and the swing member 41 drives the locking mechanism 30 to switch between the unlocked and locked states. The above structure is simple and easy to implement.

[0163] In Embodiment 3, the first direction is the forward direction, the second direction is the backward direction, the third direction is the clockwise direction, and the fourth direction is the counterclockwise direction.

[0164] As shown in Figures 28 to 44, the transmission mechanism further includes a rack portion 461 disposed on the transmission slider 46 and a gear portion 413 disposed on the swing member 41, the rack portion 461 and the gear portion 413 meshing with each other. The rack portion 461 and the gear portion 413 have simple structures and good transmission stability. The transmission slider 46 is a transmission frame, and the electric telescopic member 42 is located inside the transmission frame. In embodiment three, the first end of the swing member 41 is driven to engage with the locking mechanism 30, and the second end of the swing member 41 is provided with a engagement portion 411 that engages with the cover body 20, and the gear portion 413 is disposed at the engagement portion 411. The above structure is simple and has good transmission effect. As shown in Figures 28 to 44, a connecting post 16 is provided on the cover body 20, and the connecting part 411 is a connecting hole. The connecting hole is sleeved on the connecting post 16 to realize the connecting connection between the swing member 41 and the cover body 20.

[0165] As shown in Figures 28 to 44, the cooking appliance also includes an exhaust valve 25 and an exhaust rod 60 disposed on the lid body 20. The exhaust valve 25 has a blocking state and an exhaust state. The exhaust rod 60 is disposed between the electric telescopic member 42 and the exhaust valve 25 and moves synchronously with the electric telescopic member 42. When the locking mechanism 30 is in the unlocked state, when the electric telescopic member 42 pushes the exhaust rod 60, the exhaust rod 60 pushes the transmission mechanism to move, so that the transmission mechanism drives the locking mechanism 30 to switch from the unlocked state to the locked state, and the exhaust rod 60 drives the exhaust valve 25 to switch from the blocking state to the exhaust state. When the locking mechanism 30 is in the locked state, the transmission mechanism remains stationary, and when the electric telescopic member 42 pushes the exhaust rod 60, the exhaust rod 60 drives the exhaust valve 25 to switch from the blocking state to the exhaust state. The aforementioned exhaust linkage 60 allows the electric telescopic component 42 to simultaneously engage the locking mechanism 30 and exhaust the exhaust valve 25, thus simplifying the overall structure and effectively reducing the cost of cooking appliances.

[0166] As shown in Figures 28 to 44, the exhaust linkage 60 includes a main rod 61, a push rod 62 disposed at the first end of the main rod 61, and a linkage head 63 disposed at the second end of the main rod 61. The main rod 61 avoids the transmission mechanism, the push rod 62 cooperates with the exhaust valve 25, and the linkage head 63 cooperates with the electric telescopic component 42. Because the main rod 61 avoids the transmission mechanism, when the locking mechanism 30 is in the locked state, the transmission mechanism remains stationary, and the exhaust linkage 60 moves toward the exhaust valve 25 to drive the exhaust valve 25 to switch from the blocking state to the exhaust state. The main rod 61 is disposed on the side of the transmission slider 46, so the movement of the main rod 61 will not drive the transmission slider 46 to move.

[0167] As shown in Figures 28 to 44, a valve cover 21 is provided on the lid body 20, covering the exhaust valve 25. The valve cover 21 has an exhaust port 211 and a through hole, and a sealing element 26 is provided at the through hole. The sealing element 26 has a mounting recess, and one end of the exhaust rod 60 passes through the mounting recess and cooperates with the exhaust valve 25. The sealing element 26 can apply a restoring force to the exhaust rod 60 toward the front of the lid body 20. On the one hand, the sealing element 26 ensures the sealing of the valve cover 21, so that the gas in the cooking cavity of the pot body 10 will not be discharged from the through hole to the lid body 20. On the other hand, the sealing element 26 can provide a restoring force to the exhaust rod 60, keeping it in its initial position away from the exhaust valve 25. The sealing element 26 is made of an elastic material, such as rubber or silicone.

[0168] To improve the safety of cooking appliances, as shown in Figures 28 to 44, in Embodiment 3, the cooking appliance further includes an inner pot lid 70 located below the lid body 20. The inner pot lid 70 has a movable stop valve 71. The lid body 20 has a stop hole corresponding to the stop valve 71. The cooking appliance also includes a stop-opening sliding plate 22 on the lid body 20, which engages with the stop valve 71. A transmission mechanism is linked to the stop-opening sliding plate 22. The transmission mechanism can drive the stop-opening sliding plate to move, realizing the upward pressure stop-opening function of the cooking appliance. The transmission slider 46 of the transmission mechanism is linked to the stop-opening sliding plate 22. The transmission slider 46 has a second connecting groove 462, and the stop-opening sliding plate 22 has a linkage post that passes through the second connecting groove 462. The above-mentioned linkage post and connecting groove structure is simple and easy to implement. In embodiment three, the operating element 50 is a button structure. An opening 141 is provided on the outer casing 14, and an operating element mounting base 51 is provided at the opening 141. The button structure is mounted on the operating element mounting base 51. The operating element 50 corresponds to the middle of the movable hook 43.

[0169] In embodiment three, when assembling the pusher 47 and the locking seat 44, they are first assembled together, and a first reset member 45 (preferably a reset spring) is placed between them. These three components are then installed together in the guide portion at the front of the cover body 20 and fixed by a fixing post. The locking seat 44 has a fixing hole, which is connected to the fixing post on the cover body 20 by fasteners. The electric telescopic member 42 is installed in the mounting portion 17 on the cover body 20 and is fastened by a snap-fit. The swing member 41 is installed on the connecting post 16 of the cover body 20. The transmission slider 46 is a drive frame; the rack portion 461 on the left side of the drive frame meshes with the gear portion 413 of the swing member 41, and the second connecting groove 462 on the right side is fitted onto the linkage post of the stop-opening slide plate 22. The linkage head 63 of the exhaust linkage 60 is attached to the inner end face of the front end of the transmission frame and is set in the mounting groove 64 (as shown in Figures 28 to 44, the mounting groove is used to guide the exhaust linkage 60 in the front and rear directions). After installation, the electric telescopic component 42 pushes forward to drive the exhaust linkage 60, the exhaust linkage 60 pushes the transmission frame forward, the transmission frame drives the swing component 41 to rotate, so that the jaws are in the engagement position, and at the same time the right side of the drive frame drives the stop-opening slide plate to move forward to unlock the stop-opening valve and move it upward. After the electric telescopic component 42 finishes its operation, it returns to its original position (returning to its original position means retraction), and the exhaust linkage 60 also returns to its original position, separating from the front end face of the transmission frame. The drive frame does not have external force to keep its position unchanged. At this time, when the exhaust linkage 60 is restarted, it only drives the exhaust linkage 60 to move forward, and after it finishes, it returns to its original position together. When the exhaust linkage 60 moves forward, the exhaust linkage 60 pushes the exhaust valve (also known as the pressure relief valve) to move and exhaust air. When the exhaust linkage 60 cannot be pushed back to the exhaust valve after resetting, the exhaust valve will seal.

[0170] A fixing post is provided on the lower surface of the middle plate 13, which is used to connect the hook mounting base 85. The pivot part 434 of the movable hook 43 is installed in the engagement hole of the hook mounting base 85. The hook part 432 of the movable hook 43 is installed in the clearance hole 131 of the middle plate. A second reset member 84 is installed at the middle position of the movable hook 43. In the free state, the movable hook 43 is located on the front side of the clearance hole 131.

[0171] When it is necessary to open the cover, press the operating component 50. The movable hook 43 moves backward and disengages from the latching surface of the latching platform 11. At the same time, during the disengagement process, the movable hook 43 pushes against the pushing component 47. The pushing component 47 drives the transmission slider 46 to move backward. The transmission slider 46 drives the swing component 41 to rotate. At the same time, the swing component 41 drives the anti-opening slide plate 22 to move back to the open position. Then, the swing component 41 drives the locking mechanism 30 to rotate and disengage to the open position, and the cover is opened.

[0172] When the lid is closed, the movable hook 43 engages with the locking surface of the locking platform 11 first, and the locking mechanism 30 does not engage with the locking teeth on the inner pot 12. If cooking is required, simply select the function on the lid, and the electric telescopic component 42 will activate, pushing the exhaust rod 60 to rotate the swing component. This technical solution features a simple structure and manufacturing process, stability and reliability, ease of production, and low cost. It also offers advantages such as easier operation and reduced user error.

[0173] Example 4 of the cooking utensil is shown in Figures 45 to 60, and is detailed below:

[0174] As shown in Figures 45 to 60, an embodiment of the lid assembly includes: a lid, a swing member 41, a transmission slider 46, and an electric telescopic member 42. The lid is used to open and close on the pot body 10 of the cooking appliance, and the lid includes a lid body 20 and a locking mechanism 30 movably disposed on the lid body 20. o The locking mechanism 30 has a locked state for locking the pot body 10 and an unlocked state for unlocking the pot body 10. A swing member 41 is swingably mounted on the lid body 20, and the swing member 41 is in a transmission engagement with the locking mechanism 30. An operating part 48 is provided on the swing member 41. A transmission slider 46 is movably mounted on the lid body 20 along the lateral direction of the lid body 20, and the transmission slider 46 is in a transmission engagement with the swing member 41. An electric telescopic member 42 is provided on the lid body 20. The electric telescopic member 42 can drive the transmission slider 46 to move and cause the swing member 41 to swing in a first direction, thereby switching the locking mechanism 30 from an unlocked state to a locked state. The operating part 48 can drive the swing member 41 to swing in a second direction, thereby switching the locking mechanism 30 from a locked state to an unlocked state. The first and second directions are opposite.

[0175] Applying the technical solution of this application, the pot body and lid have a locking mechanism, which locks the locking mechanism to the pot body. In this application, when the lid is closed, the electric telescopic member 42 drives the transmission slider 46 to move and causes the swing member 41 to swing in the first direction, so that the locking mechanism 30 switches from the unlocked state to the locked state. The electric telescopic member and the swing member cooperate to achieve the locking between the locking mechanism and the pot body. When the lid is opened, the user can operate the operating part 48, so that the operating part 48 can drive the swing member 41 to swing in the second direction, so that the locking mechanism 30 switches from the locked state to the unlocked state, completing the locking and unlocking operation. The first direction and the second direction are opposite. Therefore, in the solution of this application, the lid closing operation can be performed electrically, which simplifies the user's operation steps. The lid opening operation can be achieved by the user operating the operating part, that is, it can be completed manually, which facilitates one-button or one-step lid opening. In this way, even in the event of a power outage, movement of the cooker body, or unplugging the power supply, the lid can still be opened normally by operating the transmission slider. The technical solution of this application effectively solves the problem in related technologies where the lid cannot be opened in the event of a power outage.

[0176] The first direction mentioned above refers to forward, leftward, or clockwise; the second direction refers to backward, rightward, or counterclockwise. The term "lateral" refers to the left-right direction of the cookware body.

[0177] As shown in Figures 45 to 60, the electric telescopic component 42 is a solenoid valve. The valve stem (i.e., the push rod portion 421 in the following text) of the solenoid valve engages with the transmission slider. The solenoid valve has a simple structure, good structural stability, and low cost. The solenoid valve includes a valve body and a valve stem. When the solenoid valve is energized, the valve stem extends and retracts intermittently. The extension of the valve stem can push the transmission slider to move. Of course, the electric telescopic component 42 can also be other structures, such as an electric push rod, a cylinder, etc., as long as it can realize the function of pushing the transmission slider to move. In the embodiment, after the valve stem pushes the transmission slider to move, it will automatically return to the retracted position. The solenoid valve includes a return spring that drives the valve stem. The above structure ensures that when the locking mechanism 30 is in the locked position, there is a gap between the transmission slider and the valve stem. When the cover is opened, when the operating component 50 drives the transmission slider to move, the valve stem will not contact the transmission slider, thus requiring less driving force, thereby reducing the user's operating force and improving the user experience. The electric telescopic component 42 is installed in the mounting part 17 on the cover body 20 and is fastened by a snap fastener.

[0178] The first end of the swing member 41 is driven and engaged with the locking mechanism 30, and the second end of the swing member 41 is provided with a hinge portion 411 that hinges with the cover body 20. The gear portion 413 is provided at the hinge portion 411. The above structure is simple and has a good transmission effect. The cover body 20 is provided with a connecting post 16, and the hinge portion 411 is a hinge hole. The hinge hole is sleeved on the connecting post 16 to realize the hinge connection between the swing member 41 and the cover body 20.

[0179] As shown in Figures 45 to 60, the operating part 48 is angled to the swing member 41. When the user manually operates the operating part 48, this angled arrangement more effectively transmits force to the swing member 41, causing it to swing in a second direction (opposite to the first direction), thereby unlocking the locking mechanism 30. This design optimizes the operating feel, making the opening operation smoother.

[0180] As shown in Figures 45 to 60, the swing member 41 is provided with a gear part 413, and the transmission slider 46 is provided with a rack part 461 that meshes with the gear part 413. Through the meshing of the gear part 413 and the rack part 461, the linear motion of the electric telescopic member 42 can be converted into the rotational motion of the swing member 41, thereby realizing the locking and unlocking of the locking mechanism 30. The above transmission method not only improves the transmission efficiency but also ensures the stability of the operation.

[0181] As shown in Figures 45 to 60, the transmission slider 46 is a transmission frame 463 movably arranged along the lateral direction of the cover body 20. The electric telescopic component 42 includes a main body 422 arranged along the lateral direction of the cover body 20 and a push rod 421 telescopically arranged on the main body 422. The push rod 421 is located inside the transmission frame 463, and the extension and retraction direction of the push rod 421 is consistent with the lateral direction. The above design ensures that the push rod 421 of the electric telescopic component 42 can accurately push the transmission frame 463, thereby driving the swing component 41 to complete the locking and unlocking actions. At the same time, since the transmission frame 463 moves in the lateral direction, the above structure can more effectively utilize the internal space of the cover body 20, reduce the internal volume occupied by the cover assembly, and make the cover assembly design more compact.

[0182] As shown in Figures 45 to 60, the transmission frame 463 has a first working position close to the main body 422 and a second working position away from the main body 422 when it moves. When the push rod 421 extends, it pushes the transmission slider 46 from the first working position to the second working position. The push rod 421 can retract automatically. When the operating part 48 drives the swing member 41 to swing in the second direction, the swing member 41 drives the transmission frame 463 from the second working position to the first working position. By designing the moving position of the transmission frame 463 as the first and second working positions, the consistency of the locking mechanism 30's actions during locking and unlocking can be ensured. The automatic retraction function of the push rod 421 ensures that the locking mechanism 30 can quickly reset under user operation in the unlocked state without external power, thereby improving the usability and safety of the cooking appliance in the event of a power outage.

[0183] The transmission frame 463 is provided with a clearance notch 464 that allows the rear end of the electric telescopic member 42 to pass through. The transmission slider 46 moves from the first working position to the second working position, and the rear end of the electric telescopic member 42 passes through the clearance notch 464. The design of the clearance notch 464 ensures that the rear end of the electric telescopic member 42 can pass freely when the transmission frame 463 moves. This not only simplifies the structure of the cover assembly, but also ensures that the extension and retraction of the push rod 421 is not obstructed, so that the electric telescopic member 42 can smoothly drive the transmission frame 463 to move and complete the locking or unlocking of the locking mechanism 30.

[0184] As shown in Figures 45 to 60, the cover assembly also includes a pusher movably mounted on the cover body 20. The pusher engages with the operating part 48, causing the operating part 48 to swing the swinging part 41 in a second direction. By adding the pusher, additional torque is provided to the operating part 48, making it easier to drive the swinging part 41 to complete the unlocking action. This design, especially during manual operation, reduces the force required by the user, improving ease of use and user experience. The direction of movement of the pusher is perpendicular to the lateral direction.

[0185] As shown in Figures 45 to 60, a driving ramp 481 is provided on the upper part of the pusher facing the operating part 48. The driving ramp 481 can push and cooperate with the operating part 48. The design of the driving ramp 481 utilizes the principle of ramps, which can convert the linear force applied by the user to the operating part 48 into the rotational force of the pusher, thereby more effectively driving the swinging member 41 to swing. The above design not only simplifies the operation steps, but also improves the response speed of the mechanism.

[0186] The operating part 48 is an extension plate connected to the swing member 41. The extension plate cooperates with the drive inclined surface 481. When the transmission frame 463 is in the second position, the tilt angle of the extension plate relative to the front-rear direction is the same as the tilt angle of the drive inclined surface. The swing difference of the extension plate is greater than 1 and 0.

[0187] As shown in Figures 45 to 60, the cover assembly also includes an exhaust valve 25 and an exhaust rod 60 disposed on the cover body 20. The exhaust valve 25 has a blocking state and an exhaust state. The exhaust rod 60 is movably disposed on the cover body 20 and moves synchronously with the electric telescopic member 42. When the locking mechanism 30 is in the unlocked state, when the electric telescopic member 42 pushes the exhaust rod 60, the exhaust rod 60 pushes the transmission slider 46, causing the transmission slider 46 to drive the swing member 41 to swing in a first direction, so that the swing member 41 drives the locking mechanism 30 to switch from the unlocked state to the locked state. Furthermore, the exhaust rod 60 drives the exhaust valve 25 to switch from the blocking state to the exhaust state. When the locking mechanism 30 is in the locked state, both the transmission slider 46 and the swing member 41 remain stationary. When the electric telescopic member 42 pushes the exhaust rod 60, the exhaust rod 60 drives the exhaust valve 25 to switch from the blocking state to the exhaust state. By combining the switching of the sealing state and the control of the venting state of the vent valve 25 with the locking and unlocking actions of the locking mechanism 30, the function of automatic venting during cooking is achieved without the need for additional control structures such as venting buttons. When the locking mechanism 30 switches to the locked state, the vent valve 25 automatically switches to the sealing state, ensuring pressure stability during cooking; when the locking mechanism 30 switches to the unlocked state, the vent valve 25 automatically switches to the venting state, ensuring rapid and safe pressure release, thereby improving the safety and efficiency of cooking.

[0188] The aforementioned "synchronous movement" refers to the fact that when the exhaust connecting rod 60 is extended by the electric telescopic member 42, it is driven to push the transmission slider 46 from the first working position to the second working position. When the transmission slider 46 is in the second working position, the exhaust connecting rod 60 retracts, and the seal mounted on the valve cover of the exhaust connecting rod 60 rebounds (see below) to ensure that the exhaust connecting rod 60 and the electric telescopic member 42 move synchronously.

[0189] As shown in Figures 45 to 60, the exhaust linkage 60 includes a main rod body 61, a push rod 62 disposed at the first end of the main rod body 61, and a linkage head 63 disposed at the second end of the main rod body 61. The main rod body 61 is located above the swing member 41. The push rod 62 cooperates with the exhaust valve 25, and the linkage head 63 cooperates with the electric telescopic member 42. The transmission slider 46 is a transmission frame 463. When the transmission frame 463 moves, it has a first working position and a second working position. The linkage head 63 extends into the transmission frame 463, and the electric telescopic member 42 pushes the linkage head 63, so that the linkage head 63 pushes the transmission frame 463 from the first working position to the second working position. The linkage design of the exhaust linkage 60 with the electric telescopic component 42 and the transmission frame 463 ensures that the switching of the exhaust valve 25's blocking state and the automatic control of the exhaust state are synchronized with the locking and unlocking actions of the locking mechanism 30, avoiding safety risks caused by manual operation of the exhaust valve 25 during cooking. At the same time, the cooperation between the linkage head 63 and the transmission frame 463 optimizes the structural layout, reduces action delay, and improves the smoothness and reliability of the overall operation.

[0190] As shown in Figures 45 to 60, a valve cover 21 is provided on the lid body 20, covering the exhaust valve 25. The valve cover 21 has an exhaust port 211 and a through hole, and a sealing element 26 is provided at the through hole. The sealing element 26 has a mounting recess, and one end of the exhaust rod 60 passes through the mounting recess and cooperates with the exhaust valve 25. The sealing element 26 can apply a restoring force to the exhaust rod 60 towards the front of the lid body 20. On the one hand, the sealing element 26 ensures the sealing of the valve cover 21, so that the gas in the cooking cavity of the pot body 10 will not be discharged from the through hole to the lid body 20. On the other hand, the sealing element 26 can provide a restoring force to the exhaust rod 60, keeping it in its initial position away from the exhaust valve 25. The sealing element 26 is made of an elastic material, such as rubber or silicone.

[0191] To improve the safety of the cooking appliance, in this embodiment, the cooking appliance also includes an inner pot lid 70 disposed below the lid body 20. The inner pot lid 70 is provided with a movable stop valve 71. The lid body 20 is provided with a stop hole corresponding to the stop valve 71. The cooking appliance also includes a stop-opening sliding plate 22 disposed on the lid body 20. The stop-opening sliding plate 22 engages with the stop valve 71, and a transmission slider is linked to the stop-opening sliding plate 22. The transmission slider can drive the stop-opening sliding plate to move, realizing the upward pressure stop-opening function of the cooking appliance. The transmission slider 46 is linked to the stop-opening sliding plate 22. The transmission slider 46 is provided with a second connecting groove 462, and the stop-opening sliding plate 22 is provided with a linkage post, which passes through the second connecting groove 462. The above-mentioned linkage post and connecting groove structure is simple and easy to implement. The cooking appliance also includes a top cover 23 disposed above the lid body 20.

[0192] Embodiment four of the cooking appliance includes a pot body 10 and a lid assembly disposed on the pot body 10, the lid assembly being the aforementioned lid assembly. Since the aforementioned lid assembly can solve the problem in the related art that the lid cannot be opened in the event of a power outage, the cooking appliance including this lid assembly can solve the same technical problem.

[0193] Embodiment four of the cooking appliance includes a pot body 10 and a lid assembly covering the pot body 10. The lid assembly is the same as described above, as shown in Figures 45 to 60. The pot body 10 has a retaining plate 11, and the pusher is a movable hook 43. The movable hook 43 has a locking position that engages with the retaining plate 11 and a releasing position that disengages from the retaining plate 11. The cooking appliance also includes an operating member 50 movably disposed on the pot body 10. When the operating member 50 is triggered, it can drive the movable hook 43 to switch from the locking position to the releasing position, and the movable hook 43 drives the swing member 41 to swing in a second direction, so that the swing member 41 drives the locking mechanism 30 to switch from the locked state to the unlocked state. By setting the linkage between the movable hook 43 and the operating member 50, the automatic unlocking function of the double locking mechanism between the lid assembly and the pot body 10 is realized. This design not only improves the efficiency of opening the lid after cooking, but also enhances the connection stability between the lid and the pot body through the engagement and disengagement of the movable hook 43 with the mounting plate 11. This further ensures pressure and temperature control during cooking, thereby improving the safety of the cooking appliance and the stability of the cooking effect. The movable hook 43 includes a body part 431 and a hook part 432. The body part 431 is slidably disposed on the lid body 20 along the front-back direction and engages with the operating member 50. The body part 431 allows the movable hook 43 to slide on the lid body 20, forming a pushing engagement with the operating member 50. The swing member 41 drives the transmission slider 46 to move, realizing the movement of the movable hook 43 during manual operation, which in turn triggers the movement of the transmission slider 46. The hook portion 432, driven by the main body portion 431, engages or disengages with the latch portion 11, thereby ensuring a stable connection and convenient opening and closing between the lid body 20 and the pot body 10. A driving ramp 481 is provided on the main body portion 431. The movable hook 43 also includes a push top 433 provided at one end of the main body portion 431, and the driving ramp 481 is provided on the push top 433.

[0194] It should be noted that the pot body includes an outer pot and an inner pot 12 disposed within the outer pot. The pot teeth are disposed on either the outer pot or the inner pot. The outer pot includes an outer shell 14 and a heat-insulating cover disposed within the outer shell 14, with the pot teeth disposed on the heat-insulating cover. Alternatively, the outer pot includes the outer shell 14, a middle plate 13 disposed on the top of the outer shell 14, and a pressure-bearing ring disposed above the middle plate 13, with the pot teeth disposed on the pressure-bearing ring. In this embodiment, the pot teeth are disposed on the inner pot. The outer pot also includes a base 15, with a retaining plate 11 disposed on the middle plate 13, and the inner pot 12 located inside the outer shell 14.

[0195] It should be noted that the locking mechanism includes a locking ring or locking cover that is rotatably mounted on the lid body. The locking ring or locking cover has cover teeth that engage or disengage with the pot teeth. Alternatively, in other embodiments, the locking mechanism may include a clamp structure that moves radially along the lid body. The clamp structure has cover teeth that engage or disengage with the pot teeth. Or, the locking mechanism may include a flap with cover teeth that is flipped onto the lid body, allowing the cover teeth to engage or disengage with the pot teeth. When the cover teeth are engaged with the pot teeth, the locking mechanism is in a first locked position; when the cover teeth are disengaged from the pot teeth, the locking mechanism is in an unlocked position.

[0196] It should be noted that the left-right direction of the pot body refers to the direction from left to right when the cooking utensils are placed facing the user. The user's left side is the left side of the pot body, and the user's right side is the right side of the pot body. The front-back direction of the pot body refers to the direction from front to back when the cooking utensils are placed facing the user. The side of the pot body facing the user is the front, and the side away from the user is the back.

[0197] The pot teeth in this application can be the pot rim, a raised edge, or an outward-flared edge, and the lid teeth can be the lid rim, a raised edge, or an inward-flared edge.

[0198] In this embodiment, the operating element 50 is a button structure. An opening 141 is provided on the housing 14, and an operating element mounting base 51 is provided at the opening 141. The button structure is mounted on the operating element mounting base 51. The operating element 50 corresponds to the middle of the movable hook 43.

[0199] As shown in Figures 45 to 60, the cooking appliance also includes a lever mounting base 83 disposed within the pot body 10, and a lever 80 is mounted on the lever mounting base 83. A second resetting member 84 is also disposed between the lever 80 and the pot body 10. OAs a feasible approach, the main body is movably mounted on the pot body 10 along the front-to-back direction of the cooking appliance. As shown in Figures 45 to 60, the operating member 50 is located on the side of the lever member 80 away from the interior of the pot body 10, and is situated between the pivot part 81 and the drive part 82. This arrangement ensures that the operating member 50 can effectively drive the lever member 80 to swing during user operation, thereby causing the movable hook 43 to switch from the engaged position to the disengaged position via the drive part 82 of the lever member 80. This results in smooth manual operation and improves operational efficiency and reliability.

[0200] As shown in Figures 45 to 60, the lid body 20 is provided with an abutment 24. The bottom of the movable hook 43 extends downward through the abutment 24 into the pot body 10. The design of the abutment 24 allows the movable hook 43 to smoothly engage with the latching part 11, forming a locking mechanism. This design not only ensures the movement trajectory of the movable hook 43 but also avoids interference between the movable hook 43 and the lid body 20 when opening the lid, ensuring the smooth opening and closing of the lid body 20 and improving the overall performance of the cooking appliance and the user experience.

[0201] In this embodiment, when the movable hook 43 is assembled onto the cover body 20, a first reset member 45 (preferably a reset spring) is provided between them. The movable hook 43 and the first reset member 45 are installed together in the guide portion at the front of the cover body 20 and fixed by a fixing post. The electric telescopic member 42 is installed in the mounting portion 17 on the cover body 20 and is fastened by a snap fastener. The swing member 41 is installed on the connecting post 16 of the cover body 20. The transmission slider 46 is a drive frame. The rack portion 461 on the left side of the drive frame meshes with the gear portion 413 of the swing member 41, and the second connecting groove 462 on the right side is fitted onto the linkage post of the stop slide plate 22. The linkage head 63 of the exhaust connecting rod 60 is attached to the inner end face of the front end of the transmission frame and is provided in the mounting groove 64 (as shown in Figures 45 to 60, the mounting groove is used to guide the exhaust connecting rod 60 in the front and rear directions). After installation, the electric telescopic component 42 pushes forward, driving the exhaust connecting rod 60. The exhaust connecting rod 60 pushes the transmission frame forward, causing the transmission frame to rotate the swing component 41, bringing the jaws to the engaged position. Simultaneously, the right side of the drive frame moves the stop-opening slide forward to unlock the stop-opening valve. After the electric telescopic component 42 completes its operation, it returns to its original position (retraction). The exhaust connecting rod 60 also returns to its original position, separating from the front end face of the transmission frame. Without external force, the drive frame remains in its current position. When the exhaust connecting rod 60 is restarted, it only moves forward, returning to its original position after the operation ends. When the exhaust connecting rod 60 moves forward, it pushes the exhaust valve (also known as the pressure relief valve) to move and release air. When the exhaust connecting rod 60 returns to its original position and cannot push the exhaust valve, the exhaust valve seals.

[0202] As shown in Figures 45 to 60, a fixing post is provided on the lower surface of the middle plate 13. The fixing post is used to connect the lever mounting base 83. O The pivot part 81 of the lever 80 is installed in the engagement hole of the lever mounting base 83. The drive part 82 of the lever 80 is installed in the clearance hole 131 of the middle plate. A second reset part 84 is installed at the middle position of the lever 80. In the free state, the lever 80 is located on the front side of the clearance hole 131.

[0203] When the lid needs to be opened, press the operating element 50. The lever element 80 moves backward, pushing the movable hook 43 backward and disengaging it from the engagement surface of the locking platform 11. Simultaneously, during disengagement, the movable hook 43 pushes against the operating element 50, driving the transmission slider 46 backward from the second working position to the first working position via the swing element 41. The transmission slider 46 drives the swing element 41 to rotate, simultaneously moving the anti-opening slide plate 22 back to the open position. Then, the swing element 41 drives the locking mechanism 30 to rotate and disengage to the open position, opening the lid. When closing the lid, the movable hook 43 engages with the engagement surface of the locking platform 11 first, but the locking mechanism 30 does not engage with the locking teeth on the inner pot 12. For cooking, simply select the function on the lid to activate the electric telescopic element 42, which pushes the exhaust rod 60 to engage the swing element. This technical solution features a simple, stable, and reliable structure and manufacturing process, is easy to produce, and has low cost. It is also more convenient to operate and less prone to user errors.

[0204] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this application.

[0205] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
