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 various functional components installed on the lid to control the appliance's operation. These include locking mechanisms to ensure the lid stays securely closed during use, and pressure relief devices to control the connection between the cooking space and the outside environment. Locking mechanisms usually consist of pawls and connecting rods, using a relatively long transmission chain to achieve locking and releasing actions, requiring high stability in the movement trajectory. Pressure relief devices are generally independently installed. The internal structure of the lid is complex, making assembly and maintenance difficult.

[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] The electromagnet assembly is installed onto the cover.

[0009] A driving component is movably disposed on the cover in the vertical direction;

[0010] A first locking member is installed to the cover. The first locking member includes a guide member and a fastening member that are connected by transmission. The guide member is slidably connected to the electromagnet assembly. The guide member can move relative to the electromagnet assembly in a first lateral direction under the force of the driving member, so that the fastening member can move between a fastening position that defines the relative position of the inner pot and the cover and a separation position that unlocks the inner pot.

[0011] According to the cooking appliance of this utility model, the sliding connection between the guide member and the electromagnet assembly provides stable guidance for the movement of the first locking member. By utilizing the electromagnet assembly as both the guide and support structure for the guide member in the first locking member, the internal space of the lid is significantly saved, achieving a compact structure. Simultaneously, when the driving member applies a vertical force, a specific mechanical transmission structure converts the force into a lateral movement force for the guide member, fully utilizing the internal space of the lid and making the overall structure of the cooking appliance even more compact.

[0012] Optionally, the electromagnet assembly includes a magnetic field generating device, which is fixedly connected to the cover; the guide member has a guide groove, which is slidably fitted onto the magnetic field generating device. According to this solution, the guide member can slide smoothly along the magnetic field generating device due to the guide groove.

[0013] Optionally, the length of the guide groove along the first transverse direction is M1, and the length of the portion of the electromagnet assembly that is slidably connected to the guide groove along the first transverse direction is M2, wherein M2:M1 = 0.6:1 to 0.8:1. According to this solution, the guide component has sufficient sliding stroke, and at any sliding position, it maintains a sufficiently large contact and mating area, effectively preventing jamming, shaking, or tilting during movement, thus improving the smoothness and reliability of the movement.

[0014] Optionally, the cooking appliance further includes a transmission component connected to the drive component and the guide component, used to convert the pushing force applied by the drive component into a driving force of the guide component along the first lateral direction; the first locking component includes: a drive frame connected to the guide component, and moving along a third lateral direction in response to the driving force of the guide component along the first lateral direction, the first lateral direction being substantially perpendicular to the third lateral direction; a fastening component connected to the drive frame, the fastening component being movable with the movement of the drive frame; wherein the fastening component located at the fastening position is closer to the center of the inner pot than the fastening component located at the disengagement position. According to this solution, the vertical force of the drive component is efficiently converted into the lateral movement of the drive frame, thereby driving the fastening component to move radially along the inner pot, achieving fastening and disengagement with the edge of the inner pot, resulting in a stable lock.

[0015] Optionally, the cover further includes: a mounting plate with a groove, the drive frame being slidably connected to the groove; and a base with an opening, the magnetic field generating device being located within the opening, the through direction of the opening being perpendicular to the first transverse direction, and the mounting plate being detachably installed to the opening. According to this solution, the installation of the magnetic field generating device and the first locking component is integrated into a single module, simplifying the assembly process and optimizing the internal structural layout of the cover.

[0016] Optionally, the slide groove is located on the upper surface of the mounting plate. According to this solution, the mounting plate separates the drive frame and the guide component, saving space while avoiding interference between them.

[0017] Optionally, the two drive frames are spaced apart along the third lateral direction, and the plurality of fastening members are divided into two groups, each group connected to a corresponding drive frame. Each drive frame is movable along the third lateral direction to move its connected group of fastening members. The two drive frames are connected to the guide member; when the drive member is operated, it causes the guide member to move 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, by synchronously driving the two drive frames to move in opposite directions through a guide member, synchronous driving of the two groups of fastening members is achieved, resulting in coordinated and consistent actions.

[0018] Optionally, along the third lateral direction, the electromagnet assembly is located between the two drive frames. According to this design, the electromagnet assembly located in the middle will not affect the movement of the drive frames.

[0019] Optionally, the transmission component is configured as a swing arm rotatable relative to the cover about a pivot axis; the swing arm includes a first end and a second end, the first end being connected to the driving component and the second end being connected to the guide component; wherein, when the driving component is operated, the swing arm can rotate relative to the cover about the pivot axis to drive the guide component to move along the first lateral direction. According to this solution, the vertical movement of the driving component is converted into the lateral movement of the guide component through the swing arm, realizing the conversion of the direction of motion and the transmission of force.

[0020] Optionally, the electromagnet assembly includes an electromagnetic drive rod movably connected to the magnetic field generating device along the first lateral direction; a cooking space is formed between the lid and the inner pot, the lid having a connecting hole for connecting the cooking space to the outside, and the electromagnetic drive rod moving along the first lateral direction to open or seal the connecting hole. According to this solution, intelligent, multi-segmented, and precisely programmed control of the connecting hole is achieved, thereby controlling the pressure relief of the cooking space.

[0021] Optionally, the electromagnet assembly further includes a sealing element, which is installed on the cover and located on the movement path of the electromagnetic drive rod, for sealing the connecting hole; wherein the electromagnetic drive rod directly or indirectly pushes the sealing element to open the connecting hole. According to this solution, the connecting hole is opened by the electromagnetic drive rod pushing the sealing element, thus achieving reliable opening of the pressure relief channel.

[0022] Optionally, the sealing component includes: a limiting seat, fixedly disposed on the cover, with the communicating hole located within the orthographic projection area of ​​the limiting seat on the cover, the limiting seat having a clearance hole extending along the first transverse direction; and a sealing ball, movably accommodated within the limiting seat; wherein the electromagnetic drive rod movably passes through the clearance hole to push the sealing ball when the electromagnetic drive rod moves. According to this solution, the cooperation of the sealing ball and the limiting seat achieves reliable sealing and smooth opening of the communicating hole.

[0023] Optionally, the cover body is further provided with a second locking member, which is convexly connected to the driving member. The driving member can drive the second locking member to move along a second lateral direction between a second unlocked position (unlocking the housing) and a second locked position (locking the housing). According to this solution, by simultaneously controlling the first and second locking members through the driving member, dual locking of the cover body and the pot body is achieved, simplifying the operation.

[0024] Optionally, the driving component is movable vertically between an actuated position and a resting position under the action of an external force; the cooking appliance is configured such that, with the lid covering the pot body, the driving component is in the resting position, the first locking component is in the first locked position, and the second locking component is in the second locked position. According to this solution, when the cooking appliance is closed, all components are in their initial locked positions, ensuring cooking safety and sealing.

[0025] Optionally, the second locking member further includes an additional position located between the second unlocked position and the second locked 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.

[0072] Reference Figures 1-18 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] In a sealed environment, the steam generated by heating cannot escape, causing the pressure inside the cooking space 111 to rise, and the boiling point of water to rise accordingly. This high-temperature, high-pressure environment can significantly shorten cooking time and more thoroughly break down food, making it soft and tender, and releasing nutrients more fully. If pressure relief is needed after pressure cooking or during cooking, the lid 200 is provided with a connecting hole 203 to connect the cooking space 111 to the outside, safely releasing the pressure to the target pressure value. Specifically, the connecting hole 203 is located in the removable lid 230, serving as the most direct channel for connecting the pressure inside the cooking space 111 to the outside. The lid 200 is also provided with a sealing element 730. The sealing element 730 can open or close the connecting hole 203. When a sealed pressurization is required, the sealing element 730 closes the connecting hole 203, blocking the channel. When pressure relief is required, the sealing element 730 is removed from the connecting hole 203, opening the channel and allowing steam to escape. To achieve efficient steam discharge, the connecting hole 203 is generally located in the central area of ​​the cover 200.

[0080] The cover 200 is also equipped with an electromagnet assembly 700, which can control the movement of the sealing member 730, achieving intelligent, multi-segment, and precise control according to program requirements. The electromagnet assembly 700 includes a magnetic field generating device 710 and an electromagnetic drive rod 720. The magnetic field generating device 710 can drive the electromagnetic drive rod 720 to move along the first lateral direction D1. The magnetic field generating device 710 is fixedly connected to the cover 200. The sealing member 730 is located on the movement path of the electromagnetic drive rod 720, and the electromagnetic drive rod 720 directly or indirectly pushes the sealing member 730 to open the communicating hole 203.

[0081] The sealing component includes a limiting seat 731 and a sealing ball 733. The limiting seat 731 is used to accommodate and restrict the range of motion of the sealing ball 733, so that the sealing ball 733 can only roll and move slightly within the design-permitted range. The limiting seat 731 is fixedly disposed on the cover 200, and the connecting hole 203 is located within the orthogonal projection area of ​​the limiting seat 731 on the cover 200. The limiting seat 731 is provided with a clearance hole 732 extending along a first transverse direction. The sealing ball 733 is movably accommodated within the limiting seat 731. The electromagnetic drive rod 720 is movably passed through the clearance hole 732 to push the sealing ball 733 when the electromagnetic drive rod 720 moves.

[0082] The cooking appliance is configured such that: the electromagnetic drive rod 720 is not energized and is in a retracted state, with its front end located outside the clearance hole 732; the sealing ball 733, under its own weight or the slight pressure inside the pot, falls onto the connecting hole 203, sealing it. The control system issues a pressure relief command, and the electromagnetic drive rod 720 moves along the first lateral direction D1, passing through the clearance hole 732. The end of the electromagnetic drive rod 720 directly applies a force along the first lateral direction D1 to the sealing ball 733, opening the connecting hole 203 and releasing high-pressure steam, thus achieving pressure relief. After pressure relief is completed, the electromagnetic drive rod 720 is de-energized and retracts under the action of an internal spring, exiting the clearance hole 732 and disengaging from the sealing ball 733.

[0083] 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.

[0084] 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.

[0085] The first lateral direction D1 is 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. This means the first locking member 400 can move horizontally, with simple and efficient operation. This layout also allows the first locking member 400 to occupy a more compact space on the lid 200.

[0086] 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 between an actuated position and a resting position along the vertical direction D0. 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. The first lateral direction D1 is approximately perpendicular to the vertical direction D0.

[0087] The internal space of the lid is extremely valuable. The electromagnet assembly 700 is typically installed in the center of the lid 200 or near the sealing element 730 to drive the sealing element 730 via the shortest path. The first locking element 400 includes a guide element 430 and a fastening element 420 connected by a drive mechanism. The fastening element 420 is distributed circumferentially around the inner pot, and the guide element 430 is driven by the drive element 300 to move the fastening element 420. Therefore, in this solution, by slidingly connecting the guide element 430 to the electromagnet assembly 700, the electromagnet assembly 700 can simultaneously drive the sealing element 730 and serve as a guide and support structure for the guide element 430 in the first locking element 400. This solution utilizes the space and structural strength of existing components, eliminating the need for a separate complex guide support for the first locking element 400, thus significantly saving internal space in the lid 200 and achieving a compact structure.

[0088] As described above, the electromagnetic drive rod 720 moves along the first lateral direction D1. Optionally, the guide member 430 moves along the first lateral direction D1.

First locking component 400

[0090] The following is in conjunction with the appendix Figure 1 To be continued Figure 4 , Figure 12 and Figure 13 The structure of the first locking member 400 according to an embodiment of the present invention will be described in detail.

[0091] The first locking member 400 is mounted to the cover 200 and includes a guide member 430 and a fastening member 420 that are connected by a transmission. The guide member 430 is slidably connected to the electromagnet assembly 700 and is movable relative to the electromagnet assembly 700 in a first lateral direction D1 under the force of the drive member 300, so as to drive the fastening member 420 to move between a fastening position that defines the relative position of the inner pot 110 and the cover 200 and a disengaging position that unlocks the inner pot 110.

[0092] As described above, the electromagnet assembly 700 includes a magnetic field generating device 710 and an electromagnetic drive rod 720. The electromagnet assembly 700 makes the movement trajectory of the first locking member 400 more precise and stable.

[0093] In some embodiments, the guide member 430 is directly slidably connected to the electromagnet assembly 700. Specifically, the guide member 430 is formed with a guide groove 433, which is slidably connected to the magnetic field generating device 710.

[0094] In other embodiments, the guide 430 is indirectly slidably connected to the electromagnet assembly 700. The cover 200 includes a base 260 for mounting the electromagnet assembly 700. Optionally, the base 260 is fixedly connected to the cover 200, providing a stable and reliable mounting base for the electromagnet assembly 700. The magnetic field generating device 710 is mounted within the base 260, and the guide 430 is slidably connected to the base 260.

[0095] Optionally, the base 260 includes an opening 261 for mounting the electromagnet assembly, the through direction of which is perpendicular to the first lateral direction D1. The electromagnet assembly 700 is located within the opening 261. The cover 200 also includes a mounting plate 250, which is detachably mounted to the opening 261 to provide a stable mounting environment for the electromagnet assembly 700. Optionally, the mounting plate 250 can further serve as a moving track for the first locking member 400, as described below. This solution integrates the mounting of the electromagnet assembly 700 and the first locking member 400 into a single module, simplifying the assembly process and further optimizing the internal structural layout of the cover 200. Optionally, the opening 261 faces upward, i.e., the mounting plate 250 is mounted above the base 260.

[0096] Optionally, the guide member 430 has a guide groove 433 for sliding connection with the base 260. During assembly, the corresponding portion of the base 260 is located within the guide groove 433, forming a sliding fit. The length of the guide groove 433 along the first transverse direction D1 is M1, and the length of the portion of the base 260 that is slidingly connected to the guide groove 433 (i.e., the portion inserted into the guide groove 433) along the first transverse direction D1 is M2, wherein M2:M1 = 0.6:1 to 0.8:1. Preferably, M2:M1 = 0.7:1.

[0097] Based on this proportional limitation, the guide groove 433 is ensured to have sufficient length, thereby providing the necessary sliding stroke for the guide member 430 and ensuring that the fastening member 420 can move fully between the fastening and disengaging positions. Simultaneously, the length M2 of the sliding portion of the base 260 is sufficiently long (more than half the stroke M1), ensuring that a sufficiently large contact and mating area is maintained between the guide member 430 and the base 260 in any sliding position. This effectively prevents the guide member 430 from jamming, wobbling, or tilting during movement, greatly improving the smoothness and reliability of the first locking member 400's movement and ensuring the precise execution of locking and unlocking actions.

[0098] 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, thus tightly connecting the lid 200 and the inner pot 110. The engaging position of the fastening member 420 corresponds to the first locking position of the first locking member 400, and the disengaged position of the fastening member 420 corresponds to the first unlocking position of the first locking member 400. Specifically, refer to... Figure 12 When 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...) Figure 13 When the first locking member 400 is in the first unlocked position, the fastening member 420 is in the separated position. The fastening member 420 and the inner pot 110 are offset 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.

[0099] 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.

[0100] 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.

[0101] To ensure simultaneous operation of the fastening elements 420, the first locking element 400 further includes a drive frame 410. The drive frame 410 is mounted to the cover 200 and connected to the guide element 430, and moves in a third lateral direction in response to the driving force of the guide element 430 in a first lateral direction. The mounting plate 250 of the cover 200 is provided with a groove 255, and the drive frame 410 is slidably connected to the groove 255. Optionally, the groove 255 is located on the upper end face of the mounting plate 250. This arrangement separates the drive frame 410 and the guide element 430 by the mounting plate 250, saving space and avoiding interference between the drive frame 410 and the guide element 430.

[0102] Each fastener 420 is connected to a drive frame 410. The fasteners 420 are divided into two groups. The two groups of fasteners 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 member 400 moves from the first locked position to the first unlocked position, the first and second drive frames move in opposite directions along the third transverse direction D3, thus opening relative to each other. The two groups of fasteners 420 are respectively connected to the first and second drive frames. By setting two drive frames 410, a uniform and balanced force can be 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 perpendicular includes, but is not limited to, an absolute 90-degree perpendicularity; its main purpose is to emphasize that the third transverse direction D3 and the first transverse direction D1 are significantly different and intersecting, and 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, but 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 the direction of movement of the drive frame), it can be covered by "approximately vertical".

[0103] 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.

[0104] To efficiently utilize the space of the cover 200, the electromagnet assembly 700 is positioned between the two drive frames 410 along the third transverse direction D3. When the drive frames 410 move along the third transverse direction, the electromagnet assembly 700 located in the middle will not be affected in its operation.

[0105] The following is in conjunction with the appendix Figure 3 To be continued Figure 4 Appendix Figure 12 To be continued Figure 13 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.

[0106] 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 3 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.

[0107] 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.

[0108] 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.

[0109] 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.

[0110] 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.

[0111] 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.

[0112] [Transmission mechanism of drive component 300 driving first locking component 400]

[0113] As described above, two drive frames 410 are provided to achieve synchronous driving of the two sets of fastening parts 420. The drive frame 410 is connected to the guide member 430, which can drive the two drive frames 410 to move synchronously. The cover 200 is also provided with a transmission member 600. The transmission member 600 is connected to the drive member 300, and the guide member 430 is connected to the transmission member 600 and the drive frame 410. The force of the drive member 300 is transmitted to the drive frame 410 through the transmission member 600 and the guide member 430.

[0114] 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.

[0115] 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).

[0116] 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.

[0117] 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.

[0118] 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.

[0119] 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.

[0120] Reference Figure 16 and Figure 17 The second transmission hole 621 includes a connected sliding portion 622, a first engaging portion 623, and a second engaging portion 624. The first engaging portion 623 is at least partially an annular segment. The second engaging portion 624 is also at least partially an annular segment. The centers of the annular segments of the first engaging portion 623 and 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 locking position; that is, the first engaging portion 623 corresponds to the first locking 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.

[0121] 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.

[0122] The following is in conjunction with the appendix Figure 12 To be continued Figure 13 The connection structure between the drive frame 410 and the guide member 430 according to an embodiment of the present invention will be described in detail.

[0123] 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.

[0124] 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.

[0125] 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.

[0126] In this design, to enhance the locking of the lid 200, the cooking appliance is further provided with 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 the second lateral direction D2 of the cooking appliance (e.g., the front-to-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 liner 220 and at least a portion of the pot body 100 are fixed 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.

[0127] 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."

[0128] The second lateral direction D2 is approximately parallel to the main body of the lid 200. Specifically, when the lid 200 is closed onto the pot body 100, and the cooking appliance is in an upright position, the main body of the lid 200 is approximately parallel to the horizontal plane. This means the second locking member 500 can move horizontally, with simple and efficient operation, resulting in a more compact space occupied by the first locking member 400 and the second locking member 500 on the lid 200.

[0129] In this design, the first lateral direction D1 and the second lateral direction D2 are approximately perpendicular to the vertical direction D0. The driving component 300, the first locking component 400, and the second locking component 500 form a mutually orthogonal motion transmission system. The movement of the driving component 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 components respectively.

[0130] 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.

[0131] 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.

[0132] 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.

[0133] 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 the lid is closed. In this solution, the second locking member 500 also includes an additional position located between the second locked position and the second unlocked position. Optionally, the additional position is an intermediate state position of the second locking member 500 between the second locked position and the second unlocked position. The additional position constitutes a "locking point" or "half-end holding position" of the second locking member 500. The second locking position, the additional position, and the second unlocked position are arranged along the second lateral direction D2 of the cooking appliance (i.e., the front-to-back direction of the cooking appliance).

[0134] 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 held in the first unlocked position.

[0135] 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.

[0136] 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.

[0137] 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 unlocked position.

[0138] 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.

[0139] 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.

[0140]

Second Locking Component 500

[0141] The following is in conjunction with the appendix Figure 1 To be continued Figure 2 The structure of the second locking member 500 according to an embodiment of the present invention will be described in detail.

[0142] As can be seen from the foregoing, the second locking member 500 has a second unlocking position, an actuating position, and a second locking position.

[0143] The housing 120 includes a first locking portion 101. Optionally, the first locking portion 101 is connected to the middle plate 130. 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.

[0144] 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.

[0145] 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.

[0146] 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.

[0147] 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.

[0148] [Transmission mechanism of drive component 300 driving second locking component 500]

[0149] The following is in conjunction with the appendix Figure 1 To be continued Figure 4 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.

[0150] To actuate the second locking member 500 via the driving member 300: Optionally, the driving member 300 is 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 abut against the second locking member 500. The second locking member 500 can move on the third inclined surface 311 to drive the second locking portion 510 to move relative to the first locking portion 101, thereby achieving unlocking. Optionally, 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 abut against the driving member 300. The driving member 300 can move on the fourth inclined surface 521 to drive the second locking portion 510 to move relative to the first locking portion 101, thereby achieving 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.

[0151] 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. Specifically, 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.

[0152] 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.

[0153] 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 arrangement of 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.

[0154] The driving component 300 is in the actuated position, and the second locking component 500 is in the additional position.

[0155] 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.

[0156] 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.

[0157] 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.

[0158] 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.

[0159] [When the cover 200 is closed, the second locking component 500 automatically engages.]

[0160] 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.

[0161] When the lid 200 is in the state of not covering the pot body 100, at least one of the surfaces of the first locking part 101 for contacting the second locking part 510 and the surfaces 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.

[0162] Optionally, 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, and 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, and 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.

[0163] 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.

[0164] 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.

[0165] 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.

[0166] In some embodiments, refer to Figure 2 , Figure 16 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 16 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.

[0167] 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 16 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.

[0168] Reference Figure 16 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.

[0169] 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.

[0170] 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.

[0171] 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.

[0172] 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.

[0173] 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.

[0174] Optionally, refer to 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.

[0175] 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.

[0176] Optionally, refer to Figure 1 and Figure 2 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.

[0177] Optionally, button 800 is exposed outside cover 200. Actuator 300 is located inside cover 200.

[0178] By separating the button 800 and the drive component 300, the drive component 300 can be freely adjusted in position within the cooking appliance cover 200 according to factors such as internal space layout and transmission requirements, without restricting the installation and movement of the button 800.

[0179] Optionally, refer to Figure 1 and Figure 2 The cover 200 also includes a fifth elastic element 810, which is connected to the button 800 and is used to apply an elastic force to the button 800 to move it toward an initial position. Optionally, the fifth elastic element 810 includes, but is not limited to, a compression spring and a tension spring.

[0180] Optionally, the cover 200 further includes a sixth elastic element 320, which is connected to the drive element 300 and is used to apply an elastic force toward the resting position to the drive element 300. Optionally, the sixth elastic element 320 includes, but is not limited to, a compression spring or a tension spring.

[0181] In this design, the vertical direction D0, the first horizontal direction D1, the second horizontal direction D2, and the third horizontal direction D3 are all bidirectional. With the pot body 100 in a horizontal and upright position, and the lid 200 closed on top of the pot body 100, the vertical direction D0 includes both upward and downward directions; the first horizontal direction D1 includes both forward and backward directions; the second horizontal direction D2 includes both forward and backward directions; and the third horizontal direction D3 includes both left and right directions.
