Description

Technical Field

[0001] This utility model relates to a cooking utensil. Background Technology

[0002] Traditional cooking appliances, such as rice cookers and pressure cookers, typically have a pot lid locking mechanism and a shell lid locking mechanism to ensure a stable lock during use. These mechanisms often require separate operation via two different control components. For example, one button or knob controls the locking and unlocking of the pot lid, while another controls the locking and unlocking of the shell lid. Users must operate two different control components to lock and unlock both the pot lid and the shell lid, increasing the complexity and tediousness of the operation.

[0003] Therefore, there is a need to provide a cooking appliance that can at least partially solve the above problems. Utility Model Content

[0004] The utility model description section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This utility model description section is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0005] To at least partially solve the above problems, this utility model provides a cooking utensil, comprising:

[0006] A pot body, the pot body comprising a shell and a pot interior located within the shell;

[0007] A lid, which is foldably disposed on the pot body;

[0008] A drive element is movably disposed on the cover body. The drive element is used to receive an external force applied by the user and is movable in the vertical direction between an actuated position and a resting position under the action of the external force.

[0009] The first locking member is movably disposed on the cover and has a first locking position that defines the relative position of the inner pot and the cover and a first unlocking position that unlocks the inner pot.

[0010] A transmission component is connected to the drive component and the first locking component. The transmission component converts the driving force of the drive component in the vertical direction into a pushing force applied to the first locking component in the first transverse direction, which is approximately perpendicular to the axial direction of the inner pot.

[0011] The second locking member is movably disposed on the cover and has a second locking position for locking the housing and a second unlocking position for unlocking the housing; the second locking position and the second unlocking position are arranged along a second transverse direction, the second transverse direction is approximately perpendicular to the axial direction of the pot liner, and the second transverse direction is approximately parallel to the first transverse direction;

[0012] The cooking appliance is configured such that, when the lid is closed over the pot body, and the driving member is moved to the actuated position by the external force, the driving member moves the first locking member from the first locked position to the first unlocked position, and moves the second locking member from the second locked position to the second unlocked position.

[0013] According to the cooking appliance of this utility model, the user only needs to operate one drive component to simultaneously or according to preset logic control the first locking component and the second locking component. Compared with the solution that requires operating two different control components to control two locking components separately, the operation process is greatly simplified and the number of operation steps is reduced. The first locking component is connected to the drive component through a transmission component to realize the transmission of force and the conversion of direction. The drive component drives the transmission component to move along the first transverse direction and the second locking component along the second transverse direction through vertical force, resulting in a compact structure, optimized spatial layout, and efficient transmission. At the same time, the vertical force makes it easier for the user to apply force and operate. Since the movement directions of the first locking component and the second locking component are roughly parallel, the layout of the entire locking system on the lid is easier to optimize, reducing interference between parts and thus making the structure more compact.

[0014] Optionally, the cooking appliance is configured such that, with the lid covering the pot body, the drive member is in the resting position, the first locking member is in the first locked position, and the second locking member is in the second locked position. According to this solution, in the initial closed state, the first and second locking members of the cooking appliance are in the locked positions, ensuring safety and sealing.

[0015] Optionally, the first locking member includes: a guide member connected to the transmission member and movable along a first lateral direction to transmit the driving force; a drive frame driven to the guide member and moving along a third lateral direction in response to the driving force of the guide member along the first lateral direction, the first lateral direction being substantially perpendicular to the third lateral direction; and a fastening member connected to the drive frame, the fastening member being movable between a first locked position and a first unlocked position as the drive frame moves, the fastening member in the first locked position being closer to the center of the pot than the fastening member in the first unlocked position. According to this solution, the first locking member achieves radial movement of the fastening member through multi-stage transmission to lock or unlock the pot.

[0016] Optionally, the two drive frames are spaced apart along a third lateral direction, and the plurality of fastening members are divided into two groups, each group being connected to a corresponding drive frame. Each drive frame is movable along the third lateral direction to move the group of fastening members it is connected to. According to this solution, the two groups of drive frames drive multiple fastening members to move synchronously, ensuring a uniform distribution of locking force and improving operational stability and efficiency.

[0017] Optionally, the two drive frames are respectively connected to the guide member;

[0018] When operated, the drive component moves the guide component along the first lateral direction, thereby driving the two drive frames to move simultaneously or in a preset order along the third lateral direction in opposite directions. According to this solution, the movement of the guide component drives the two drive frames to move in opposite directions, realizing the opening and closing of the fastening components.

[0019] Optionally, the transmission component is configured as a rocker arm rotatable relative to the cover about a pivot axis. The rocker arm has a first end and a second end along its length. The first end is slidably connected to the driving component via a first transmission hole, and the second end is slidably connected to the guide component via a second transmission hole. The first transmission hole is configured as a long slot or a long hole; and / or, the second transmission hole is configured as a long slot or a long hole. According to this solution, the rocker arm converts the vertical motion of the driving component into the lateral motion of the guide component.

[0020] Optionally, the second transmission hole includes a sliding portion, a first engaging portion, and a second engaging portion that are connected to each other. The first engaging portion is closer to the rotating shaft than the second engaging portion. The first engaging portion is located on the side of the sliding portion away from the pot body, and the second engaging portion is located on the side of the sliding portion closer to the pot body.

[0021] When the guide is engaged with the first engagement portion, the first locking member is located in the first locking position;

[0022] When the guide member engages with the second engaging portion, the first locking member is located in the first unlocked position. According to this solution, the special structure of the second transmission hole enables the first locking member to be temporarily locked in two positions.

[0023] Optionally, a first elastic element is provided between the two drive frames. This first elastic element applies a force to the drive frames, causing them to move closer together along the third lateral direction. According to this design, the first elastic element provides a resilient force for the drive frames to reset, ensuring the locking element returns to its stable position.

[0024] Optionally, the drive frame is provided with a first guide structure extending along the first lateral direction, the first lateral direction being perpendicular to the vertical direction, and the first lateral direction being approximately perpendicular to the third lateral direction; the cover is provided with a second guide structure inclined relative to both the first lateral direction and the third lateral direction; at least a portion of the first locking member is connected to the first guide structure and the second guide structure, and is movable relative to the cover along the first guide structure and the second guide structure, wherein the first guide structure and the second guide structure are constructed as elongated slots or elongated holes. According to this solution, the movement path and speed of the first locking member are precisely controlled by the first guide structure and the second guide structure, thereby improving the accuracy and stability of locking.

[0025] Optionally, the driving member is provided with a third inclined surface for contacting the second locking member. The third inclined surface is inclined relative to both the second lateral direction and the vertical direction. During the movement of the driving member from the resting position to the actuated position, the third inclined surface guides the second locking member to move towards the second unlocked position. Alternatively, the second locking member is provided with a fourth inclined surface for contacting the driving member. The fourth inclined surface is inclined relative to both the second lateral direction and the vertical direction. During the movement of the driving member from the resting position to the actuated position, the fourth inclined surface guides the second locking member to move towards the second unlocked position. According to this solution, the inclined surface structure converts the vertical movement of the driving member into the lateral movement of the second locking member to achieve unlocking.

[0026] Optionally, the housing is provided with a first inclined surface for contacting the second locking member. The first inclined surface is inclined relative to both the second lateral direction and the vertical direction. During the closing of the cover, the first inclined surface guides the second locking member to move toward the second unlocking position. Alternatively, the second locking member is provided with a second inclined surface for contacting the housing. The second inclined surface is inclined relative to both the second lateral direction and the vertical direction. During the closing of the cover, the second inclined surface guides the second locking member to move toward the second unlocking position. According to this solution, the inclined surface structure guides the movement of the second locking member when the cover is closed to achieve automatic engagement.

[0027] Optionally, the cover body is further provided with a second elastic element, which is used to apply a force to the second locking member to move toward the second locked position. According to this solution, the second elastic element ensures that the second locking member has a stable locking tendency.

[0028] Optionally, the housing includes a first locking portion, and the second locking member further includes a second locking portion.

According to this solution, it is ensured that the driving member can effectively drive the second locking member to fully unlock.

[0032] Optionally, the second locking member further includes an additional position located between the second locked position and the second unlocked position; when the external force applied to the drive member is removed, the second locking member is located in the additional position, and at least a portion of the drive member is located in the actuated position. According to this solution, after the cooking appliance is unlocked, the drive member and the second locking member are held in a temporarily stable state and will not immediately relock, making it convenient for the user to open the lid.

[0033] Optionally, the driving member includes a third locking portion, and the second locking member includes a fourth locking portion; when the second locking member is in the additional position and the driving member is in the actuated position, the third locking portion engages with the fourth locking portion. According to this solution, the engagement of the third locking portion and the fourth locking portion achieves mutual locking between the driving member and the second locking member in the additional position after the cover is opened, thus maintaining the unlocked state.

[0034] Optionally, the second lateral direction is a bidirectional direction, the direction from the second locked position to the second unlocked position in the second lateral direction is the fourth direction, and the direction from the second unlocked position to the second locked position in the second lateral direction is the fifth direction; the third locking part is disposed on the side of the driving member facing the fourth direction. According to this solution, by limiting the setting direction of the third locking part, it is ensured that it correctly engages with the fourth locking part.

[0035] Optionally, the third locking part is constructed as a slot, and the third locking part is used to accommodate the fourth locking part; or, the fourth locking part is constructed as a slot, and the fourth locking part is used to accommodate the third locking part.

[0083] Reference Figures 1-20 This application provides a cooking appliance. The cooking appliance according to this application can be a rice cooker, electric pressure cooker or other cooking appliance with electromagnetic heating function, and in addition to the function of cooking rice, the cooking appliance can also have various functions such as cooking porridge.

[0084] The cooking appliance of this utility model includes a lid 200 and a pot body 100. The pot body 100 is used for cooking food, and the lid 200 is used to cover the pot body 100. When the lid 200 covers the pot body 100, a cooking space is formed between the lid 200 and the pot body 100.

[0085] The pot body 100 is typically a rounded cuboid shape and has a cylindrical inner pot storage section. The pot body 100 includes an inner pot 110, which can be freely placed into or removed from the inner pot storage section for easy cleaning. The inner pot 110 is typically made of metal and is used to hold materials to be heated, such as rice or soup. The inner pot 110 has a radial direction and an axial direction. The radial direction is the direction of the circle about the geometric center of the inner pot 110. The axial direction is the direction passing through the geometric center of the inner pot 110 and parallel to the height direction of the inner pot 110. Here, the geometric center of the inner pot 110, in the example where the cross-sectional shape of the inner pot 110 is circular, is the exact center or center of the circle of the inner pot 110.

[0086] The pot body 100 also includes a middle plate 130 and a shell 120. The middle plate 130 is disposed at the top of the pot body 100, and the shell 120 is disposed at the side and bottom of the pot body 100. The middle plate 130 is fixedly installed to the shell 120. Optionally, when the lid 200 is closed on the pot body 100, the lid 200 and the inner pot 110 are sealed together. Through the sealed connection between the lid 200 and the inner pot 110, the cooking appliance can adapt to pressure cooking.

[0087] The lid 200 has a shape substantially corresponding to the pot body 100. The lid 200 is closable on the pot body 100; specifically, it is pivotally connected to the pot body 100 via a pivot axis 140 and can freely pivot about the pivot axis 140 between a closed position and an open position relative to the pot body 100, facilitating the closing and opening of the pot body 100. Optionally, a fourth elastic element 150 for assisting in opening the lid is provided between the lid 200 and the pot body 100. In some embodiments, the fourth elastic element 150 is constructed as a torsion spring, with its two arms connected to the lid 200 and the pot body 100, respectively. Optionally, the torsion spring is sleeved onto the pivot axis 140.

[0088] When the lid 200 is closed over the pot body 100, the lid 200 and the inner pot 110 are sealed together to accommodate pressure cooking. The lid 200 includes a top cover 210, a liner 220, and a removable cover 230. The top cover 210 is located on the outermost side of the lid 200, forming the outer shell of the lid 200. The liner 220 is located below the top cover 210 and is connected to the top cover 210. For example, the liner 220 can be connected to the top cover 210 by fasteners or clips, and the top cover 210 and the liner 220 constitute the upper cover assembly. The upper cover assembly is mainly used to centrally mount various functional components of the lid 200 that sense and control the working status of the cooking appliance, such as sensors. The removable cover 230 is located on the innermost side of the lid 200 and is located below the liner 220. The removable cover 230 is detachably connected to the liner 220, for example, by mounting it to the liner 220 via a removable cover 230 mounting bracket, for easy cleaning and replacement. The removable cover 230 is oriented toward the cooking space, that is, when the cover 200 is in the closed position, the removable cover 230 is located directly above the cooking space.

[0089] It should be noted that the directional terms used in this article to describe the various parts and components of the cooking appliance, such as "up and down," "left and right," and "front and back," are relative to the cooking appliance when it is placed horizontally and upright with the lid 200 closed to the pot body 100. When the cooking appliance is placed on a surface, the direction facing the surface is downward, and the direction away from the surface is upward. Understandably, when the lid 200 is open, the approximate front-back direction of the lid 200 is the up and down direction, the approximate up and down direction is the back-forward direction, and the approximate left-right direction is the left and right direction. Unless otherwise specified, the up and down, front-back, and left and right directions are generally defined from the user's perspective when facing the pot body 100 upright. The side closer to the user is the front, and the side farther from the user is the back. When the user is facing the pot body 100, the user's left side corresponds to the left side of the pot body 100, and the user's right side corresponds to the right side of the pot body 100. In addition, unless otherwise specified, the "inner" in directional terms such as "inward", "outward", "towards", "inner side", "outer side", etc., refers to the center of the pot body 100, and the "outer" refers to the center of the pot body 100.

[0090] In the description of this application, it should be understood that the terms "upper", "lower", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship when the product is in normal use (i.e., when the lid is closed). They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0091] In this design, when the cooking appliance is in operation, especially during high-pressure cooking, the high-temperature and high-pressure environment inside the pot body 100 will exert a thrust on the lid 200. The removable lid 230 is located directly above the inner pot 110, and the removable lid 230 will withstand a huge upward thrust from inside the cooking space.

[0092] To ensure the sealing of the cooking appliance during operation, a first locking member 400 is provided. The first locking member 400 is used to lock or unlock the lid 200 and the inner pot 110. The first locking member 400 is movably disposed on the lid 200 and has a first locking position defining the relative position of the inner pot 110 and the lid 200, and a first unlocking position unlocking the inner pot 110. Optionally, the first locking position and the first unlocking position are arranged along a first lateral direction D1 of the cooking appliance (such as the front-to-back direction of the cooking appliance). In the first locking position, the first locking member 400 applies or transmits a locking force to the inner pot 110, thereby locking the inner pot 110 to maintain the seal between the inner pot 110 and the lid 200; in the first unlocking position, the first locking member 400 releases the locking force, and the seal between the inner pot 110 and the lid 200 is released. Optionally, when the first locking member 400 is in the first locked position, at least a portion of the removable cover 230 (e.g., the edge of the removable cover 230) and at least a portion of the inner pot 110 (e.g., the edge of the inner pot 110) are fixed by the first locking member 400.

[0093] The cooking appliance also includes a second locking member 500. The second locking member 500 is used to lock or unlock the lid 200 and the pot body 100. The second locking member 500 is movably disposed on the lid 200 and has a second locking position for locking the housing 120 and a second unlocking position for unlocking the housing 120. Optionally, the second locking position and the second unlocking position are arranged along a second lateral direction D2 of the cooking appliance (e.g., the front-back direction of the cooking appliance). Optionally, when the second locking member 500 is in the second locking position, at least a portion of the lid 220 and at least a portion of the pot body 100 are secured by the second locking member 500. Optionally, the second locking member 500 is located at the front of the cooking appliance, and the pivot 140 between the lid 200 and the pot body 100 is located at the rear of the cooking appliance. During cooking, the second locking member 500 can reliably lock the lid 200 to ensure the sealing of the cooking appliance. After cooking, the second locking member 500 is unlocked, and the lid 200 can be flipped open backward with the pivot 140 as the fulcrum, ensuring the stability and reliability of opening and closing.

[0094] In this design, the first lateral direction D1 and the second lateral direction D2 are approximately parallel. Approximate parallelism includes, but is not limited to, absolute parallelism. It should be noted that, to accommodate the layout of internal components, avoid motion interference, or optimize mechanics, the mounting positions of the first locking member 400 and the second locking member 500 may be intentionally fine-tuned, resulting in an angular deviation (e.g., -10° to 10°) between the first lateral direction D1 and the second lateral direction D2. As long as its function and effect are not substantially different from a parallel design, it can be encompassed by the term "approximately parallel."

[0095] In this design, because the two locking components move in the same direction, the layout of the entire locking system on the cover 200 is easier to optimize, reducing interference between parts and resulting in a more compact structure. Simultaneously, the unlocking process is likely to be smoother; the user only needs to press the drive component 300 to unlock the inner pot and outer shell according to preset rules, improving operational convenience. The parallel movement direction reduces transmission complexity and improves the durability and reliability of the locking system.

[0096] Meanwhile, both the first lateral direction D1 and the second lateral direction D2 are approximately parallel to the bottom surface of the main body of the lid 200 (i.e., the end face of the removable lid 230 facing the cooking space). Specifically, when the lid 200 is closed onto the pot body 100, and the cooking appliance is in an upright position, the bottom surface of the main body of the lid 200 is approximately parallel to the horizontal plane. That is, both the first locking member 400 and the second locking member 500 can move horizontally, making the movement simple and efficient. This layout also allows the first locking member 400 and the second locking member 500 to occupy a more compact space on the lid 200.

[0097] This solution uses a double locking mechanism, first locking element 400 and second locking element 500, to ensure the sealing of the cooking appliance during operation and meet the safety requirements of the cooking appliance.

[0098] A drive member 300 is movably disposed on the lid 200. The drive member 300 receives external force applied by the user and, under the action of the external force, is movable along the vertical direction D0 between an actuated position and a resting position. When the lid 200 is closed to the pot body 100, the actuated position is below the resting position. The drive member 300 is driveably connected to the first locking member 400 and the second locking member 500. In this design, the drive member 300 directly or indirectly drives the first locking member 400 and the second locking member 500 to move.

[0099] The first lateral direction D1 and the second lateral direction D2 are approximately perpendicular to the vertical direction D0. The driving member 300, the first locking member 400, and the second locking member 500 form a mutually orthogonal motion transmission system. The movement of the driving member 300 along the vertical direction D0 is converted into lateral movement through mechanical structures (such as inclined planes, connecting rods, etc.), which control the two independent locking members respectively.

[0100] When the lid 200 is closed over the pot body 100, and the driving member 300 is moved toward the actuation position by an external force, the driving member 300 will simultaneously produce two actions. On the one hand, it moves the first locking member 400 from the first locked position to the first unlocked position, releasing the lock between the lid 200 and the inner pot 110; on the other hand, it moves the second locking member 500 from the second locked position to the second unlocked position, releasing the lock between the lid 200 and the pot body 100, thus providing conditions for opening the lid 200. The cooking utensil is constructed such that, when the lid 200 is closed over the pot body 100, as the driving member 300 is moved toward the actuation position by an external force, the driving member 300 moves the first locking member 400 from the first locked position to the first unlocked position, and also moves the second locking member 500 from the second locked position to the second unlocked position.

[0101] In this design, the user can apply a vertical force D0 to move the drive unit 300 in the vertical direction D0. This vertical force makes it easier for the user to apply force and operate the device. Simultaneously, the user's hand presses down from above the cover 200, naturally keeping their hand away from the primary direction of steam injection. The cover 200 rotates backward to open. After applying the vertical force D0, the user's hand can immediately stabilize the cover 200, participating in the opening process, and the hand remains within the safe upper area of ​​the cover 200, improving user safety and operating experience.

[0102] To ensure that the lid 200 can be closed smoothly after being opened, the first locking member 400 must be in the first unlocked position when the lid 200 is open to avoid interference between the first locking member 400 and the pot body 100 when closing the lid. In this design, the second locking member 500, in addition to having a second locking position and a second unlocking position, also has an additional position. This additional position is an intermediate state position maintained by the second locking member 500 after the user opens the lid 200 and releases the drive member 300, serving as a "locking point" or "half-end holding position". The additional position is located between the second locking position and the second unlocking position, that is, the second locking position, the additional position, and the second unlocking position are arranged along the second transverse direction D2 (i.e., the front-to-back direction) of the cooking appliance.

[0103] When the user opens the cover 200, the drive member 300 moves to the actuated position by the user's external force, thereby simultaneously unlocking the first locking member 400 and the second locking member 500. When the external force on the drive member 300 is removed, the second locking member 500 is in the additional position. Since the drive member 300 is linked to the second locking member 500 through a mechanical structure (such as an inclined plane or a connecting rod), when the second locking member 500 is stopped in the additional position, it will abut against the drive member 300, preventing it from fully resetting. This keeps at least a portion of the drive member 300 in the actuated position. When the drive member 300 is held in the actuated position, the drive member 300 is linked to the first locking member 400 through a mechanical structure (such as an inclined plane or a connecting rod), so that the first locking member 400 is stably kept in the first unlocked position.

[0104] When the user closes the lid 200, a portion of the structure on the lid 200 contacts the second locking member 500 in the additional position and applies a force to push it back to the second locking position, ultimately releasing the constraint on the drive member 300. The drive member 300, the first locking member 400, and the second locking member 500 can be fully reset. The drive member 300 returns to the resting position, the first locking member 400 locks the lid 200 and the inner pot 110, and the second locking member 500 locks the lid 200 and the pot body 100, preparing for the next high-pressure cooking and unlocking.

[0105] According to this solution, the user only needs to operate one drive unit 300 to simultaneously or according to preset logic control the first locking member 400 and the second locking member 500 to switch between locked and unlocked states. Compared with the traditional design that requires operating two different control components to control two locking components, this greatly simplifies the operation process and reduces the number of operation steps. At the same time, the second locking member 500, located in the additional position, cooperates with the drive unit 300, located in the actuated position, so that it will not immediately relock after the cooking appliance is unlocked.

[0106] The cooking appliance is constructed such that, with the lid 200 covering the pot body 100, the drive component 300 is in a resting position, the first locking component 400 is in a first locked position, and the second locking component 500 is in a second locked position. With the lid 200 open, the drive component 300 is in an actuated position, the first locking component 400 is in a first unlocked position, and the second locking component 500 is in an additional position.

[0107] In this design, when the drive component 300 is in the resting position, it is in its initial, unforced state. At this time, the lid 200 and the pot body 100 of the cooking appliance are locked. The first locking component 400 is in the first locking position, tightly locking the lid 200 and the inner pot 110; the second locking component 500 is in the second locking position, ensuring the overall locking of the lid 200 and the pot body 100. The cooking appliance is in a safe and normal cooking state. In this state, the drive component 300 allows the user to apply external force. By applying a force D0 along the vertical direction to the drive component 300, the user causes the drive component 300 to begin moving towards the actuation position. The user only needs to apply external force to the drive component 300 to trigger the entire unlocking mechanism, preparing to open the lid 200. The drive component 300 achieves mechanical linkage with the first locking component 400 and the second locking component 500 through vertical displacement D0, achieving a compact layout and saving lateral space.

[0108] When the driving member 300 moves to the actuated position under the action of an external force, the external force acting on the driving member 300 is removed, at which point the second locking member 500 remains in the additional position. This engagement ensures that the cooking appliance will not immediately relock after unlocking. Specifically, when the driving member 300 is in the actuated position, its position is related to the state of the second locking member 500 in the additional position, forming a temporary stable state. After the driving member 300 reaches the actuated position, it interacts with the second locking member 500 through its mechanical structure, preventing the second locking member 500 from immediately returning to the second locked position, thus maintaining the unlocked state. At the same time, the driving member 300 interacts with the first locking member 400 through its mechanical structure, preventing the first locking member 400 from immediately returning to the first locked position, thus maintaining the unlocked state.

[0109]

First locking component 400

[0110] The following is in conjunction with the appendix Figure 1 To be continued Figure 6 Appendix Figure 8 To be continued Figure 10 Appendix Figure 12 To be continued Figure 18 The structure of the first locking member 400 according to an embodiment of the present invention will be described in detail.

[0111] The first locking member 400 includes a fastening member 420. The fastening member 420 has an engaging position corresponding to a first locking position and a disengaging position corresponding to a first unlocking position. Optionally, the fastening member 420 has a clamping space. The fastening member 420 engages with the edge of the inner pot 110 through the clamping space, thereby tightly connecting the lid 200 and the inner pot 110. (Refer to...) Figure 12 and Figure 13When the first locking member 400 is in the first locked position, the fastening member 420 is in the fastening position, and the edge of the inner pot 110 is engaged within the clamping space of the fastening member 420. The fastening member 420 can form a stable locking state with the inner pot 110, and the fastening member 420 prevents the lid 200 from being opened. (Refer to...) Figures 5 to 6 When the first locking member 400 is in the first unlocked position, the fastening member 420 is in the separated position. The clamping space of the fastening member 420 is offset from the inner pot 110 in the vertical direction D0. At this time, there is no effective locking connection between the fastening member 420 and the inner pot 110. The fastening member 420 allows the cover 200 to be opened and the cover 200 can move freely relative to the inner pot 110.

[0112] Optionally, the fastening element 420 in the engaged position is closer to the center of the inner pot 110 than the fastening element 420 in the disengaged position. The fastening element 420 moves radially along the inner pot 110 to achieve engagement and disengagement with the edge of the inner pot 110. As mentioned above, the inner pot 110 is usually circular or nearly circular. Optionally, the fastening element 420 moves radially along the inner pot 110, which can better adapt to the circular contour of the inner pot 110. During the movement, it can more evenly contact and act with the edge of the inner pot 110, thereby effectively applying sufficient clamping force from the side to ensure the locking effect between the inner pot 110 and the lid 200, and to ensure the sealing effect of the cooking space to adapt to the high-pressure cooking environment.

[0113] Optionally, the cooking appliance includes multiple fastening elements 420. When the lid 200 is closed, the multiple fastening elements 420 are spaced apart circumferentially along the inner pot 110. The circumferentially spaced fastening elements 420 can evenly apply locking force to the edge of the inner pot 110. Optionally, the multiple fastening elements 420 are evenly distributed circumferentially along the lid 200. In this solution, the fastening elements 420 can be set with a reasonable number and angle to maximize the use of the space at the edge of the lid 200, so that the fastening elements 420 can meet functional requirements without appearing crowded, ensuring that both the lid 200 and the inner pot 110 are subjected to uniform pressure and support when the lid is closed, thereby improving stability. Optionally, the number of fastening elements 420 can be, but is not limited to, 4, 6, or 8.

[0114] To ensure simultaneous operation of the fastening elements 420, the first locking element 400 also includes a drive frame 410. Each fastening element 420 is connected to the drive frame 410. The fastening elements 420 are divided into two groups. The two groups of fastening elements 420 are spaced apart and paired along the third transverse direction D3. Correspondingly, the drive frame 410 includes a first drive frame and a second drive frame spaced apart along the third transverse direction D3. When the first locking element 400 moves from the first locked position to the first unlocked position, the first drive frame and the second drive frame move in opposite directions along the third transverse direction D3, thereby opening relative to each other. The two groups of fastening elements 420 are respectively connected to the first drive frame and the second drive frame. By providing two drive frames 410, it is possible to ensure that a uniform and balanced force is applied to both sides of the cover 200 during movement, avoiding problems such as deformation of the cover 200 or unstable locking / unlocking due to uneven force. Optionally, the third transverse direction D3 is approximately perpendicular to the first transverse direction D1. "Approximately vertical" includes, but is not limited to, absolute 90-degree verticality. Its main purpose is to emphasize that the third lateral direction D3 and the first lateral direction D1 are significantly different and intersecting. The design function in this scheme is based on this intersecting relationship. It should be noted that, in order to accommodate the layout of internal components, avoid motion interference, or perform mechanical optimization, the line connecting the first and second drive frames (in the D3 direction) may be intentionally set to an angle (e.g., 80° or 100°) with the first lateral direction D1, even if it is not 90 degrees. As long as its working principle and effect are substantially the same as the vertical design (i.e., the direction of the driving force of the drive component on the first locking component intersects with the movement direction of the drive frame), it can be encompassed by "approximately vertical."

[0115] Optionally, the main body of the drive frame 410 extends along the first transverse direction D1, and the moving direction of the drive frame 410 is set approximately perpendicular to the extending direction of its main body to achieve efficient force transmission, making the action of the fastening member 420 stable, while optimizing the spatial layout. The fastening members 420 in the same group are spaced apart along the first transverse direction D1. Optionally, the third transverse direction D3 is approximately parallel to the bottom surface of the main body of the cover 200. That is, both the drive frame 410 and the fastening member 420 can move in the horizontal direction, making the action simple and efficient. This layout also allows the space occupied by the fastening member 420 and the drive frame 410 on the cover 200 in the first locking member 400 to be more compact. The drive frame 410 converts the horizontal driving force into the radial movement of the fastening member, so that the clamping action of the fastening member 420 is directly aligned with the edge of the pot liner 110.

[0116] The following is in conjunction with the appendix Figures 8 to 10 , Figures 12 to 15 The connection structure between the drive frame 410 and the fastening member 420 according to an embodiment of the present invention will be described in detail.

[0117] The drive frame 410 is provided with a first guide structure 411, and the fastener 420 is connected to the first guide structure 411. Optionally, refer to Figure 8 , Figure 9 and Figure 11 The cover 200 is provided with a second guide structure 201, and the fastening member 420 is movably connected to the second guide structure 201. The fastening member 420 is movable along the first guide structure 411 and the second guide structure 201. When the drive frame 410 moves (e.g., operated by the drive member 300), the drive frame 410 drives the fastening member 420 to move via the first guide structure 411, causing the fastening member 420 to move along the second guide structure 201, thereby moving the fastening member 420 between an engaged position and a disengaged position.

[0118] The precise control of the moving path and speed of the fastening member 420 is achieved through the cooperation of the first guide structure 411 and the second guide structure 201. Optionally, the extension direction of the second guide structure 201 is the same as the moving direction of the fastening member 420, that is, the fastening member 420 moves along the path defined by the second guide structure 201. For example, if the second guide structure 201 is a straight elongated hole, the fastening member 420 will move in a straight line; if it is an arc-shaped hole, the fastening member 420 will swing in an arc. Optionally, the first guide structure 411 and the second guide structure 201 are constructed as elongated slots or elongated holes. The first guide structure 411 extends along the first transverse direction D1. Optionally, the second guide structure 201 is inclined relative to both the first transverse direction D1 and the third transverse direction D3. Optionally, the extension direction of the second guide structure 201 intersects the central axis of the inner pot 110 (e.g., the radial direction of the inner pot 110). The fastening element 420 can move along the radial direction of the inner pot 110. When fastening the element 420, it can be evenly stressed, which enhances the stability of the lid 200 and the pot body 100.

[0119] When the driving component 300 is subjected to external force, it can be directly driven or the force can be transmitted to the driving frame 410 relative to the cover 200 through the transmission structure, and then transmitted to the fastening component 420 through the transmission connection of the first guide structure 411 and the second guide structure 201, thereby driving the fastening component 420 to move between the fastening position and the disengaging position.

[0120] When the first locking member 400 moves from the first locked position to the first unlocked position, the first drive frame and the second drive frame open in a direction away from each other along the third lateral direction D3. Optionally, a first elastic member 413 is provided between the first drive frame and the second drive frame. The first elastic member 413 is used to apply a force to the drive frame 410 to bring the two drive frames 410 closer to each other along the third lateral direction D3. Optionally, the first elastic member 413 is a spring to ensure that the drive frame 410 can be stably and reliably automatically reset. The first elastic member 413 connects between the first drive frame and the second drive frame, which can balance the force on both during the movement. During unlocking and reset, it provides an appropriate restoring force. In addition, connecting the first elastic member 413 between the first drive frame and the second drive frame makes full use of the internal space of the cooking appliance, making the overall structure of the cooking appliance more compact. Optionally, multiple first elastic members 413 are provided to make the movement of the drive frame 410, i.e., the entire transmission structure, smoother and more stable.

[0121] To ensure the drive frame 410 can move stably along a preset trajectory, the drive frame 410 is provided with a third guide structure 412. The drive frame 410 is connected to the cover 200 through the third guide structure 412. Optionally, the third guide structure 412 is configured as a guide hole or a guide groove. The cover 200 is provided with a connector 240. The connector 240 extends into the third guide structure 412 of the drive frame 410, forming a movable connection with the third guide structure 412. For example, when the connector 240 is a pin, the pin passes through the third guide structure 412, allowing the drive frame 410 to perform specific movements along or around the pin. The drive frame 410 moves along the path defined by the third guide structure 412, thereby accurately converting the power of the drive member 300 into the movement required by the fastening member 420, thereby driving the fastening member 420 to move between the fastening position and the disengagement position.

[0122] In this design, the first guide structure 411 and the third guide structure 412 are not arranged in parallel, thereby ensuring effective linkage between the drive frame 410 and the fastener 420. Optionally, the extension trajectories or extension directions of the first guide structure 411 and the third guide structure 412 may intersect or be out of plane.

[0123] [Transmission mechanism of drive component 300 driving first locking component 400]

[0124] As mentioned above, two drive frames 410 are provided to achieve synchronous driving of the two sets of fastening parts 420. To drive the two drive frames 410 to operate synchronously, the first locking part is also provided with a guide 430, and the cover 200 is also provided with a transmission part 600. The transmission part 600 is connected to the drive part 300, and the guide 430 is connected to both the transmission part 600 and the drive frame 410. The force exerted by the drive part 300 is transmitted to the drive frame 410 via the transmission part 600 and the guide 430.

[0125] The transmission component 600 converts the driving force of the drive component 300 along the vertical direction D0 into a pushing force applied to the guide component 430 along the first transverse direction D1. Two drive frames 410 are connected to the same guide component 430. Optionally, the drive frame 410 is connected to a fifth guide structure 431 (described in detail below) on the guide component 430. When the guide component 430 moves along the first transverse direction D1, the fifth guide structure 431 drives the two drive frames 410 to move simultaneously or in a preset sequence along the third transverse direction D3 in opposite directions.

[0126] Optionally, the transmission member 600 is constructed as a rocker arm 600. The rocker arm 600 is rotatably connected to the cover 200 about a pivot 630. The axis of the pivot 630 is substantially parallel to the main surface of the cover 200. The rocker arm 600 includes a first end 610 (i.e., the first end of the transmission member 600) and a second end 620 (i.e., the second end of the transmission member 600) opposite in length direction of the rocker arm 600. The first end 610 of the rocker arm is connected to and acts on the drive member 300. The connection between the first end 610 of the rocker arm and the drive member 300 includes, but is not limited to, a hinged connection and a sliding connection (e.g., a pin connection or a connecting rod connection). The second end 620 of the rocker arm is connected to and acts on the guide member 430. The connection between the second end 620 of the rocker arm and the guide member 430 includes, but is not limited to, a hinged connection and a sliding connection (e.g., a pin connection or a connecting rod connection).

[0127] According to this solution, when the user operates the drive unit 300, the drive unit 300 will generate an initial movement. Since the first end 610 of the swing arm is connected to the drive unit 300, this initial movement will directly act on the first end 610 of the swing arm, causing the swing arm 600 to begin rotating relative to the cover 200 around the pivot 630. As the swing arm 600 rotates, the second end 620 of the swing arm will move along a specific arc trajectory. Because the second end 620 of the swing arm is connected to the guide member 430, the movement of the second end 620 of the swing arm will drive the guide member 430 to perform a corresponding movement. After the guide member 430 moves along the first lateral direction D1 under the drive of the swing rod 600, it will cooperate with the two drive frames 410 through the fifth guide structure 431 set thereon, so that the two drive frames 410 move in opposite directions. The drive frame 410 cooperates with the fastening member 420 through the first guide structure 411 set thereon, and transmits power to the fastening member 420, so that the fastening member 420 moves between the fastening position and the disengaging position, thereby realizing the locking and unlocking between the cover 200 and the pot 110.

[0128] Optionally, the rocker arm 600 is provided with a first transmission hole 611, which is located at the first end 610 of the rocker arm. The first transmission hole 611 is constructed as an elongated slot or an elongated hole. Optionally, the driving member 300 is provided with a sliding structure, such as a sliding rod or a sliding block, adapted to the shape of the first transmission hole 611, for sliding connection with the rocker arm 600. Further optionally, the driving member 300 is slidably connected to the first transmission hole 611 via a connecting member, such as a pin. In this solution, the extension trajectory or direction of the first transmission hole 611 intersects with or is not parallel to the movement trajectory of the driving member 300, thereby ensuring smooth transmission between the rocker arm 600 and the driving member 300.

[0129] The rocker arm 600 is provided with a second transmission hole 621, which is located at the second end 620 of the rocker arm. The second transmission hole 621 is constructed as an elongated slot or an elongated hole. Optionally, the guide member 430 is provided with a sliding structure, such as a sliding rod or a sliding block, adapted to the shape of the second transmission hole 621, for sliding connection with the rocker arm 600. Alternatively, the guide member 430 is slidably connected to the second transmission hole 621 via a connecting member, such as a pin. In this design, the extension trajectory or direction of the second transmission hole 621 intersects with or is not parallel to the movement trajectory of the guide member 430, thereby ensuring smooth transmission between the rocker arm 600 and the guide member 430.

[0130] The shapes and dimensions of the first transmission hole 611 and the second transmission hole 621 are precisely designed to transmit the driving force of the drive member 300 and precisely guide the movement trajectory of the guide member 430. When the drive member 300 is operated by an external force, the rocker arm 600 moves in a specific direction through the first transmission hole 611, and similarly, the guide member 430 moves in a predetermined direction through the second transmission hole 621. Optionally, the extension trajectories or extension directions of the first transmission hole 611 and the second transmission hole 621 intersect or are not parallel. That is, the first transmission hole 611 and the second transmission hole 621 are not parallel, thereby ensuring the effective linkage of the drive member 300, the rocker arm 600, and the guide member 430.

[0131] Optionally, the second transmission hole 621 includes a communicating sliding portion 622, a first engaging portion 623, and a second engaging portion 624. The first engaging portion 623 is at least partially constructed as an annular segment. The second engaging portion 624 is at least partially constructed as an annular segment. The center of the annular segment of the first engaging portion 623 and the center of the annular segment of the second engaging portion 624 are concentric with the rotating shaft 630. The first engaging portion 623 is closer to the rotating shaft 630 than the second engaging portion 624. The first engaging portion 623 is located on the side of the sliding portion 622 away from the pot body 100, and the second engaging portion 624 is located on the side of the sliding portion 622 closer to the pot body 100. When the guide member 430 engages with the first engaging portion 623, the first locking member 400 is in a first locked position; that is, the first engaging portion 623 corresponds to the first locked position of the first locking member 400. When the guide member 430 engages with the second engaging portion 624, the first locking member 400 is in the first unlocked position; that is, the second engaging portion 624 corresponds to the first unlocked position of the first locking member 400. Since the circular segment trajectory is concentric with the rotating shaft 630, it can be ensured that when the guide member 430 moves to the first engaging portion 623 and the second engaging portion 624, it can accurately correspond to the first locking position and the first unlocked position required by the first locking member 400, thereby achieving temporary locking of the first locking member 400 in the first locking position and the first unlocked position.

[0132] According to this solution, in the initial state where the lid 200 is closed to the pot body 100, the first locking member 400 is in the first locked position, and the guide member 430 is engaged with the first engaging portion 623. When the user operates the drive member 300, the drive member 300 will generate a downward movement. Since the rocker arm 600 is connected to the drive member 300, the drive member 300 presses down the first end 610 of the rocker arm, causing the first end 610 of the rocker arm to rotate upward. Since the first engaging portion 623 is located above the sliding portion 622, the guide member 430 slides out from the first engaging portion 623 to the sliding portion 622. As the rocker arm 600 continues to rotate, the guide member 430 moves backward under the guidance of the sliding portion 622 until it slides to the second engaging portion 624. During the movement of the guide member 430, the drive frame 410 moves accordingly, causing the first locking member 400 to move from the first locked position to the first unlocked position. Since the second latching part 624 is located below the sliding part 622, the guide 430 will be temporarily locked after reaching this position, thereby locking the first locking part 400 to the first unlocked position.

[0133] The following is in conjunction with the appendix Figure 1 To be continued Figure 6 Appendix Figure 8 To be continued Figure 10 Appendix Figure 12 To be continued Figure 16 The connection structure between the drive frame 410 and the guide member 430 according to one embodiment of the present invention will be described in detail.

[0134] The guide member 430 is provided with a fifth guide structure 431 that is inclined relative to both the first lateral direction D1 and the third lateral direction D3. The fifth guide structure 431 is constructed as an elongated slot or an elongated hole. At least a portion of the drive frame 410 is connected to the fifth guide structure 431 and is movable relative to the cover 200 along the fifth guide structure 431.

[0135] As described above, the two drive frames 410 are connected to the guide member 430 and can move in opposite directions. The guide member 430 is provided with a fifth guide structure 431 corresponding to the two drive frames 410. The two fifth guide structures 431 are symmetrical about an axis of symmetry extending along the first transverse direction D1 and are equidistantly distributed, so that when the guide member 430 moves along the third transverse direction D3, it synchronously drives the two drive frames 410 to move along the third transverse direction D3.

[0136] In this design, the first lateral direction D1, the third lateral direction D3, and the vertical direction D0 are all perpendicular to each other. According to this design, the vertical pressing of the drive member 300 along the vertical direction D0 is converted into the horizontal translation of the guide member 430 along the first lateral direction D1, then into the lateral movement of the drive frame 410 along the third lateral direction D3, and finally into the radial movement of the fastening member 420 along the inner pot 110. This transforms the user's vertical downward pressure into multi-directional mechanical motion, reducing the multi-directional lateral force required to directly operate the fastening member 420. The user can trigger the complex unlocking process by pressing the drive member 300 with one hand. Simultaneously, the mechanism is arranged within the limited thickness of the cover 200 using the three-dimensional perpendicular relationship, avoiding planar accumulation of transmission components.

[0137]

Second Locking Component 500

[0138] The following is in conjunction with the appendix Figure 1 To be continued Figure 10 Appendix Figure 12 To be continued Figure 15 The structure of the second locking member 500 according to an embodiment of the present invention will be described in detail.

[0139] As described above, the second locking member 500 has a second unlocked position, an actuated position, and a second locked position. The housing 120 includes a first locking portion 101. Optionally, the first locking portion 101 is connected to the middle plate 130.

[0140] The second locking member 500 includes a second locking portion 510. The cover 200 is provided with a slide groove 202, and the second locking member 500 is movably connected to the slide groove 202. As described above, the second locking position, the additional position, and the second unlocking position of the second locking member 500 are arranged along the second transverse direction of the cooking appliance, that is, the second locking member 500 can move along the front-back direction D2. Correspondingly, the slide groove 202 extends along the second transverse direction D2.

[0141] The shape and size of the second locking part 510 are adapted to the first locking part 101 to ensure that it can reliably engage with the first locking part 101 in the locked state.

[0142] The cooking appliance is constructed such that when the second locking member 500 is in the second locked position, the first locking part 101 and the second locking part 510 are engaged; when the second locking member 500 is in the second unlocked position, the first locking part 101 and the second locking part 510 are disengaged. When the first locking part 101 and the second locking part 510 are engaged, they hook together to form a mechanical locking structure, firmly locking the lid 200 onto the pot body 100, making it impossible for the lid 200 to be easily opened.

[0143] In this design, the second locking member 500 further includes a second elastic member 530. The second elastic member 530 applies a force to the second locking member 500 to move towards the second locked position, thereby ensuring that the first locking part 101 and the second locking part 510 can be tightly engaged in the non-operating state. That is, when no other external force is applied or no other structural limitation is present, the second locking member 500, located in the second unlocked position, can move towards the second locked position under the elastic force of the second elastic member 530. Optionally, the second elastic member 530 is connected between the second locking member 500 and the cover 200. Specifically, the second elastic member 530 is connected between the second locking member 500 and the liner 220. More specifically, the second elastic member 530 is located within the slide groove 202. Optionally, the second elastic member 530 includes, but is not limited to, a compression spring and a tension spring to ensure that the second locking member 500 can be stably and reliably automatically reset.

[0144] In some embodiments, when subjected to other external forces or without other structural constraints (e.g., the drive member 300 in the actuated position), the second locking member 500 in the second unlocked position moves toward the second locked position under the elastic force of the second elastic member 530, and is constrained in an additional position by the drive member 300 in the actuated position.

[0145] [Transmission mechanism of drive component 300 driving second locking component 500]

[0146] The following is in conjunction with the appendix Figure 1 To be continued Figure 10 Appendix Figure 12 To be continued Figure 15 The transmission structure of the driving member 300 and the second locking member 500 according to an embodiment of the present invention will be described in detail. At least a portion of the second locking member 500 is located on the moving path of the driving member 300. When the driving member 300 is operated, the driving member 300 can directly actuate the second locking member 500 to disengage the first locking part 101 from the second locking part 510.

[0147] To actuate the second locking member 500, the driving member 300 is optionally provided with a third inclined surface 311. During the pressing process of the driving member 300 under external force, the third inclined surface 311 serves to hold the second locking member 500, allowing the second locking member 500 to move on the third inclined surface 311 to move the second locking portion 510 relative to the first locking portion 101, thereby unlocking. Alternatively, the second locking member 500 is provided with a fourth inclined surface 521. During the pressing process of the driving member 300 under external force, the fourth inclined surface 521 serves to hold the driving member 300, allowing the driving member 300 to move on the fourth inclined surface 521 to move the second locking portion 510 relative to the first locking portion 101, thereby unlocking. The third inclined surface 311 and / or the fourth inclined surface 521 are constructed as inclined surfaces that are inclined relative to both the second transverse direction D2 and the vertical direction D0. That is, during the process of the drive member 300 moving from the resting position to the actuated position, the third inclined surface 311 and / or the fourth inclined surface 521 can guide the second locking member 500 to move toward the second unlocked position.

[0148] Optionally, only one of the third inclined surface 311 and the fourth inclined surface 521 may be provided. Alternatively, the third inclined surface 311 and the fourth inclined surface 521 may be provided correspondingly, that is, the shapes, angles, and positions of the third inclined surface 311 and the fourth inclined surface 521 may correspond. When the driving member 300 is in the resting position and the second locking member 500 is in the second locked position, at least a portion of the fourth inclined surface 521 is located below the third inclined surface 311.

[0149] Optionally, when the lid 200 is closed onto the pot body 100, and the drive member 300 is at rest (i.e., not pressed), the third inclined surface 311 and the fourth inclined surface 521 are either not in contact or in contact. The drive member 300 and the second locking member 500 are relatively independent. At this time, the second locking part 510 can engage with the first locking part 101 to close the lid 200 and the pot body 100. When the user applies external force to the drive member 300 (such as pressing the drive member 300), the drive member 300 begins to move along a predetermined moving path. During the movement of the drive member 300, at least part of the second locking member 500 is located on the moving path of the drive member 300. As the drive member 300 moves, the third inclined surface 311 gradually contacts the fourth inclined surface 521. Because of the angle between the two inclined surfaces, when the drive member 300 continues to move, the third inclined surface 311 will apply a component force perpendicular to the inclined surface 521 to the fourth inclined surface 521. This component force can be decomposed into a driving force that moves the second locking member 500. Under the action of the driving force, the second locking member 500 moves along the slide groove 202, causing the second locking part 510 to move accordingly. When the second locking part 510 moves to the second unlocking position, the second locking part 510 is disengaged from the first locking part 101. At the same time, the drive member 300 transmits the driving force to the first locking member 400, causing the first locking member 400 to move to the first unlocking position. The first locking member 400 is released from its engagement with the inner pot 110, and the lid 200 can be lifted freely upwards.

[0150] Based on the above embodiments, the driving member 300 includes a third locking portion 310, and a third inclined surface 311 is formed on the third locking portion 310. The second locking member 500 includes a fourth locking portion 520, and a fourth inclined surface 521 is formed on the fourth locking portion 520. The third locking portion 310 and the fourth locking portion 520 can engage. That is, the third inclined surface 311 and the fourth inclined surface 521 can guide the third locking portion 310 and the fourth locking portion 520 to engage. During the engagement of the third locking portion 310 and the fourth locking portion 520, the second locking member 500 transmits driving force to the second locking portion 510, causing the second locking portion 510 to disengage from the first locking portion 101. At the same time, since the driving member 300 transmits driving force to the fastening member 420 through the swing rod 600, the guide member 430, and the driving frame 410, the fastening member 420 moves towards the separation position.

[0151] The driving component 300 is in the actuated position, and the second locking component 500 is in the additional position.

[0152] To ensure that the lid 200 can close smoothly after being opened, the first locking member 400 must be in the first unlocked position when the lid 200 is open to avoid interference between the first locking member 400 and the inner pot 110 when the lid is closed. Optionally, one of the third locking part 310 and the fourth locking part 520 is configured as a groove to accommodate the other of the third locking part 310 and the fourth locking part 520. That is, one of the third locking part 310 and the fourth locking part 520 is configured as a concave-convex structure so that the third locking part 310 and the fourth locking part 520 can engage after the driving member 300 moves to the actuated position. The groove structure achieves precise engagement of the third locking part 310 and the fourth locking part 520 through geometric matching characteristics, restricts their relative displacement in space, and ensures a stable locking state. When the driving member 300 is in the actuated position and the second locking member 500 is in the additional position, the slot engages with the third locking part 310 or the fourth locking part 520.

[0153] The cooking appliance is constructed such that when the third locking part 310 and the fourth locking part 520 are engaged, the driving member 300 is in the actuated position, the second locking member 500 is in the additional position, and the first locking member 400 is in the first unlocked position. At this time, the cover 200 can be opened and closed freely.

[0154] As described above, the second locking member 500 is movable along the second lateral direction D2 between the second locked position and the second unlocked position. The second lateral direction D2 is a bidirectional direction; the direction from the second locked position to the second unlocked position is the fourth direction D4 (i.e., rearward direction), and the direction from the second unlocked position to the second locked position is the fifth direction D5 (i.e., forward direction). The third locking part 310 is located on the side of the driving member 300 facing the fourth direction D4, that is, the fourth locking part 520 is located on the side of the third locking part 310 facing the fourth direction D4. During the engagement of the third locking part 310 and the fourth locking part 520, the third locking part 310 pushes the fourth locking part 520 to move towards the fourth direction D4, and when the third locking part 310 and the fourth locking part 520 are fully engaged, the third locking part 310 prevents the fourth locking part 520 from moving towards the fifth direction D5.

[0155] Optionally, the second elastic member 530 can apply an elastic force toward the third locking part 310 (i.e., the fifth direction D5) to the fourth locking part 520, thereby ensuring that the third locking part 310 and the fourth locking part 520 can be tightly engaged in the non-operating state.

[0156] [When the cover 200 is closed, the second locking component 500 automatically engages.]

[0157] As described above, due to the engagement of the third locking part 310 and the fourth locking part 520, the second locking member 500 is in an additional position after the cover 200 is opened. In order to ensure smooth closing of the cover 200 during the closing process, when the second locking member 500 is in the additional position, the first locking part 101 is located on the movement path of the second locking part 510, that is, the first locking part 101 and the second locking part 510 can still engage.

[0158] When the lid 200 is in the state of not covering the pot body 100, at least one of the surface of the first locking part 101 for contacting the second locking part 510 and the surface of the second locking part 510 for contacting the first locking part 101 is constructed as an inclined surface that is inclined relative to both the second lateral direction D2 and the vertical direction.

[0159] The first locking portion 101 has a first inclined surface 102. During the closing process of the cover 200, the first inclined surface 102 abuts against the second locking portion 510. The second locking portion 510 can move on the first inclined surface 102 to drive the second locking member 500 to move relative to the cover 200. Optionally, the second locking portion 510 has a second inclined surface 511. During the closing process of the cover 200, the second inclined surface 511 abuts against the first locking portion 101. The first locking portion 101 can move on the second inclined surface 511 to drive the second locking member 500 to move relative to the cover 200. That is, during the closing process of the cover 200, the first inclined surface 102 and / or the second inclined surface 511 can guide the second locking member 500 to move toward the second unlocked position.

[0160] Optionally, only one of the first inclined surface 102 and the second inclined surface 511 may be provided. Alternatively, the first inclined surface 102 and the second inclined surface 511 may be provided correspondingly, that is, the shape, angle and position of the first inclined surface 102 and the second inclined surface 511 may be provided correspondingly.

[0161] Optionally, the first inclined surface 102 and / or the second inclined surface 511 are constructed as inclined surfaces that are inclined relative to both the second lateral direction D2 and the vertical direction D0. When the cover 200 is closed, the second locking part 510 contacts the inclined surface of the first locking part 101. Since the inclined surface is inclined, the second locking part 510 will apply a component force perpendicular to the inclined surface during movement. According to the principle of force decomposition, this component force can be decomposed into driving forces in the vertical direction D0 and the second lateral direction D2, causing the second locking member 500 to move towards the second unlocked position. As the cover 200 continues to press down, after the second locking part 510 is misaligned with the inclined surface of the first locking part 101, the second locking member 500 moves towards the second locked position due to the elastic force of the second elastic member 530.

[0162] As described above, during the closing process of the cover 200, the second locking part 510 of the second locking member 500 can automatically engage with the first locking part 101 due to the inclined surface. In this solution, the second locking part 510 and the fourth locking part 520 together constitute the second locking member 500, that is, when the second locking part 510 moves, the fourth locking part 520 moves synchronously. Therefore, when the second locking part 510 engages with the first locking part 101, the fourth locking part 520 disengages from the third locking part 310. The interaction force between the third locking part 310 and the fourth locking part 520 fails, and the second locking member 500 moves towards the fifth direction D5 under the elastic force of the second elastic member 530, causing the second locking member 500 to return to the second locked position. The drive frame 410 moves under the elastic force of the first elastic member 413, thereby causing the first locking member 400 to return to the first locked position. Thus, when closing the cover, there is no need to manually operate the drive member 300.

[0163] In some embodiments, refer to Figure 2 and Figure 20 The engagement amount L1 between the first locking part 101 and the second locking part 510, and the engagement amount L2 between the third locking part 310 and the fourth locking part 520 are equal, to ensure that when the third locking part 310 and the fourth locking part 520 are engaged, the first locking part 101 is disengaged from the second locking part 510; and to ensure that when the first locking part 101 and the second locking part 510 are engaged, the third locking part 310 and the fourth locking part 520 are disengaged. (Refer to...) Figure 2 The engagement amount L1 between the first locking part 101 and the second locking part 510 refers to the size of the area where the first locking part 101 and the second locking part 510 overlap, contact, and exert a restraining effect when they are engaged. Specifically, it is the length of the projections of the first locking part 101 and the second locking part 510 along the second transverse direction D2 (approximately the front-to-back direction) in the projection along the vertical direction D0 when the lid 200 is closed onto the pot body 100 and the cooking appliance is in an upright position. (Refer to...) Figure 20 The engagement amount L2 of the third locking part 310 and the fourth locking part 520 refers to the size of the area where the third locking part 310 and the fourth locking part 520 overlap, contact each other, and generate a restraining effect when they are engaged. Specifically, it is the length of the projection of the first locking part 101 and the second locking part 510 along the second transverse direction D2 (approximately the vertical direction) of the cover 200 in the projection along the thickness direction of the cover 200 when the cover 200 is open.

[0164] In practical applications, there may be instances where the first locking part 101 fails to engage or disengage with the second locking part 510, the third locking part 310, and the fourth locking part 520. In some embodiments, the driving member 300 also has a fifth inclined surface 301. When the lid 200 is closed onto the pot body 100, and when the cooking appliance is in an upright position, the fifth inclined surface 301 is located above the third locking part 310. The fifth inclined surface 301 is inclined relative to both the vertical direction D0 and the second horizontal direction D2. (Refer to...) Figure 20 The projection of the fifth inclined surface 301 along the thickness direction of the cover 200, along the second transverse direction D2 of the cover 200, is L3. Wherein, L3 > L2.

[0165] Reference Figure 20 By setting the fifth inclined surface 301, the engagement amount L2 of the third locking part 310 and the fourth locking part 520 can be less than the engagement amount L1 of the first locking part 101 and the second locking part 510. That is, L3 > L1 > L2.

[0166] During the downward pressing of the driving member 300, the third locking part 310 and the fourth locking part 520 slide relative to each other via the third inclined surface 311 and the fourth inclined surface 521, causing the second locking part 510 to move towards the second unlocking position. When the third inclined surface 311 and the fourth inclined surface 521 are misaligned, the first locking part 101 and the second locking part 510 remain engaged due to the large engagement amount. After the third inclined surface 311 and the fourth inclined surface 521 are misaligned, the driving member 300 continues to press down, and the fourth inclined surface 521 contacts the fifth inclined surface 301. Guided by the fourth inclined surface 521 and the fifth inclined surface 301, the second locking part 510 continues to move towards the second unlocking position until it reaches the second unlocking position, at which point the first locking part 101 and the second locking part 510 are disengaged. When the external force acting on the drive member 300 is removed, the second locking member 500 moves to an additional position in the fifth direction D5 under the elastic force of the second elastic member 530. At this time, the fourth locking part 520 is located between the fifth inclined surface 301 and the third inclined surface 311 in the vertical direction D0, and the drive member 300 and the second locking member 500 are engaged through the third locking part 310 and the fourth locking part 520.

[0167] Due to the engagement of the third locking part 310 and the fourth locking part 520, the second locking member 500 is in an additional position after the cover 200 is opened. To ensure smooth closing of the cover 200 during the closing process, when the second locking member 500 is in the additional position, the first locking part 101 is located on the movement path of the second locking part 510, that is, the first locking part 101 and the second locking part 510 can still engage. To avoid accidental engagement, the second locking member 500 also includes a slider 103 and a third elastic member 104. The slider 103 is located below the first locking part 101 and is movable in the vertical direction D0. The slider 103 has a first position that contacts the first locking part 101 and a second position that is spaced apart from the first locking part 101. When the slider 103 is in the second position, the first locking part 101 can engage with the second locking part 510. The third elastic element 104 is connected to the slider 103 and applies an elastic force to the slider 103 to move it toward the first position. After the slider 103 moves to the first position, it comes into close contact with the first locking part 101, thereby effectively preventing the second locking part 510 from engaging with the first locking part 101 again during the opening process. Optionally, the third elastic element 104 is a compression spring.

[0168] The slider 103 protrudes from the first locking portion 101 along the fourth direction D4. Optionally, in the projection along the vertical direction D0, the slider 103 is closer to the inner pot 110 than the first locking portion 101. Alternatively, the first locking portion 101 has a notch to expose a portion of the slider 103.

[0169] In this design, at least a portion of the slider 103 is located on the movement path of the second locking member 500. During the opening process, the driving member 300 drives the second locking part 510 to disengage from the first locking part 101, and the slider 103 moves to the first position under the elastic force of the third elastic member 104. At this time, the slider 103 contacts the first locking part 101 to prevent the second locking part 510 from engaging with the first locking part 101. During the closing process, the second locking member 500 moves downward, and the second locking part 510 contacts the protruding slider 103, enabling the slider 103 to move downward to the second position, where the second locking part 510 engages with the first locking part 101. Simultaneously, due to the action of the inclined surface, the second locking member 500 moves along the fourth direction D4, thereby causing the fourth locking part 520 to move to disengage from the third locking part 310, completing the relocking of the lid 200 and the pot body 100.

[0170] During the closing process, guided by the first inclined surface 102 and the second inclined surface 511, the second locking member 500 moves towards the fourth direction D4. Due to the small engagement amount of the third locking part 310 and the fourth locking part 520, the third locking part 310 and the fourth locking part 520 are disengaged first. Guided by the first inclined surface 102 and the second inclined surface 511, the second locking member 500 continues to move towards the fourth direction D4 until the first inclined surface 102 and the second inclined surface 511 are misaligned. The cover 200 continues to press down, and the first locking part 101 engages with the second locking part 510.

[0171] Reference Figure 2 When the first locking part 101 and the second locking part 510 are engaged, the projection along the vertical direction D0, the distance between the front end of the second locking part 510 and the rear end of the slider 103 along the second transverse direction D2 is L4. Where L3 ≥ L4. By limiting this distance, during unlocking, the distance the driving member 300 drives the second locking part 510 to move is greater than the effective distance between the second locking part 510 and the first locking part 101. When the driving member 300 is activated, it ensures that the first locking part 101 and the second locking part 510 are disengaged, and the slider 103 can abut against the first locking part 101 under the elastic force of the third elastic member 104, thereby preventing the second locking part 510 from accidentally engaging with the first locking part 101.

[0172] As described above, the fourth elastic element 150 provides the elastic force to open the lid 200. Optionally, the second locking element 500 is disposed opposite to the fourth elastic element 150. During the opening process, the user operates the drive element 300, the second locking element 500 moves to the second unlocked position, and the first locking element 400 moves to the first unlocked position, thereby releasing the locking state between the lid 200 and the pot body 100. At this time, the elastic potential energy stored in the fourth elastic element 150 begins to be released, pushing the lid 200 to open. The torque assistance of the fourth elastic element 150 makes it easier for the user to open and close the lid.

[0173] Optionally, refer to Figures 1 to 6 The cover 200 also includes a button 800. The button 800 is for user operation, is vertically movable, and is arranged vertically with the drive member 300. The button 800 can actuate the drive member 300, thereby moving the transmission member 600 and the second locking member 500. The drive member 300 and the button 800 interact through contact surfaces. Optionally, when the button 800 moves vertically, its lower end face can contact a corresponding part of the drive member 300, applying a force to the drive member 300 to initiate its operation.
