Description

Technical Field

[0001] This utility model relates to the field of small household appliance technology, and more specifically, to a cooking utensil. Background Technology

[0002] The cooking utensil includes a pot body and a lid. The pot body has a welt, and the lid has a mechanism that engages with the welt. A handle is located on the top surface of the lid; holding the handle drives the lid to rotate relative to the pot body, allowing the lid to engage or disengage with the pot body.

[0003] The cooking appliances in the related technology also include a locking structure provided on the pot body. The locking structure has a locking position that locks the lid to the pot body and an unlocking position that allows the lid to be separated from the pot body.

[0004] When a user opens the lid, they must first hold the handle on the lid to rotate it relative to the pot, and then operate the locking mechanism on the pot to switch it to the unlocked position. This requires the user to adjust the operating position and move back and forth between the pot and the lid when opening the lid, making the operation rather complicated. Utility Model Content

[0005] The main purpose of this utility model is to provide a cooking appliance that solves the problem in related technologies where users need to operate back and forth between the pot body and the lid when opening the lid, which is a complicated operation.

[0006] To achieve the above objectives, this utility model provides a cooking utensil, comprising: a pot body, a lid, a rotating component, a second locking mechanism, an operating component, a lower transmission component, and an upper transmission component. The pot body is provided with a toothed edge. The lid is placed on the pot body and includes a lid body and a first locking mechanism disposed below the lid body. The first locking mechanism is rotatably disposed relative to the lid body and has a first unlocking position separating from the toothed edge and a first locking position engaging with the toothed edge. The rotating component is rotatably disposed on the lid body. The second locking mechanism is movably disposed on the pot body and has a second locking position locking the lid on the pot body and a second unlocking position unlocking the lid so that it can be opened from the pot body. The operating component is movably disposed on the pot body and can rotate and move. The lower transmission component is movably disposed on the pot body along the left-right direction. The upper transmission component is movably disposed on the lid body along the left-right direction. The operating component drives the rotating component to rotate through the transmission cooperation between the lower and upper transmission components. When the second locking mechanism is in the second locked position, the rotation of the operating member drives the lower transmission member to move, which in turn drives the rotating member to rotate via the upper transmission member, causing the rotating member to switch the first locking mechanism between the first unlocked position and the first locked position. When the first locking mechanism is in the first unlocked position, the movement of the operating member drives the second locking mechanism to switch the second locking mechanism from the second locked position to the second unlocked position.

[0007] By applying the technical solution of this utility model, the first locking mechanism of the lid can engage with the pot teeth of the pot body to be in the first locked position, and the second locking mechanism can move to lock the lid onto the pot body to be in the second locked position, thus enabling a tighter connection between the pot body and the lid. When the user needs to open the lid, the user can rotate the operating component to drive the rotating component to rotate through the lower and upper transmission components, so that the first locking mechanism switches from the first locked position to the first unlocked position. The user drives the operating component to move, so that the second locking mechanism switches to the second unlocked position, allowing the lid to be opened from the pot body. In this way, when the user opens the lid, the first locking mechanism can switch to the first unlocked position and the second locking mechanism can switch to the second unlocked position simply by rotating and moving the operating component. This allows the user to open the lid simply by operating the operating component, without the need to adjust the operating position, reducing the steps required to operate back and forth between the pot body and the lid when opening the lid, making the operation convenient for the user. Therefore, the technical solution of this application effectively solves the problem in related technologies where users need to operate back and forth between the pot body and the lid when opening the lid, which is a relatively complex operation. Furthermore, the cover is opened by rotating and moving the operating component. One operating component can achieve two movements: switching the first locking mechanism and switching the second locking mechanism, which improves the ease of opening the cover.

[0008] Furthermore, the cooking appliance also includes a gear transmission structure mounted on the pot body. The operating component engages with the lower transmission component via the gear transmission structure to drive the lower transmission component to move. The gear transmission structure is simple and compact in structure, and the transmission is reliable.

[0009] Furthermore, the gear transmission structure includes a first gear and a rack that meshes with the first gear. One of the first gear and the rack is disposed on the operating member, and the other of the first gear and the rack is disposed on the lower transmission member. This converts the rotational motion of the operating member into linear motion, so that the operating member can drive the lower transmission member to move via the gear transmission structure. Alternatively, the gear transmission structure includes a second gear and a third gear that meshes with the second gear. One of the second gear and the third gear is disposed on the operating member, and the other of the second gear and the third gear is disposed on the lower transmission member. This transmits the rotation of the operating member to the lower transmission member, so that the lower transmission member can be driven to move by the gear transmission structure.

[0010] Furthermore, the gear transmission structure includes a first gear and a rack that meshes with the first gear. One of the first gear and the rack is fixedly mounted on the operating member, and the other is fixedly mounted on the lower transmission member. The operating member can drive the second locking mechanism through the first gear and the rack. This converts the rotational motion of the operating member into linear motion, allowing the operating member to drive the lower transmission member to move via the gear transmission structure. It also makes the rotation of the first gear and the movement of the lower transmission member more stable and reliable.

[0011] Furthermore, the operating element is movably mounted on the pot body along the front-to-back direction. The cooking appliance also includes an elastic element disposed between the pot body and the operating element. The elastic element applies a restoring force to the operating element, wherein the restoring force points from the rear of the pot body to the front of the pot body. The elastic element facilitates the reset of the operating element, enabling the operating element to hold the second locking mechanism in the second locked position or the second unlocked position when not subjected to force applied by the user.

[0012] Furthermore, the lower transmission component includes a lower transmission body and a lower coupling portion disposed on the lower transmission body. The lower transmission body is in transmission engagement with the operating component. The upper transmission component includes an upper transmission body and an upper coupling portion disposed on the upper transmission body. The upper transmission body is drivenly connected to the rotating component, and the lower coupling portion is in transmission engagement with the upper coupling portion. In this way, when the operating component rotates, it can drive the lower transmission body and the lower coupling portion to move. The lower coupling portion drives the upper coupling portion on the upper transmission body to move, so that the upper transmission body can drive the rotating component to rotate, which facilitates the switching of the first locking mechanism between the first unlocked position and the first locked position.

[0013] Furthermore, one of the lower coupling part and the upper coupling part is a coupling groove, and the other of the lower coupling part and the upper coupling part is a coupling block inserted into the coupling groove. The arrangement of the coupling groove and the coupling block is simple and the transmission is reliable.

[0014] Furthermore, the lower transmission component includes a first transmission section that engages with the operating component and a second transmission section that engages with the upper transmission component. A support boss is provided on the pot body to support the second transmission section. The support boss supports the second transmission section, making its movement smoother and more reliable. The lower transmission component also includes a connecting section between the first and second transmission sections, and the support boss has a clearance hole to avoid the connecting section. The connecting section makes the connection between the first and second transmission sections more reliable.

[0015] Furthermore, the upper transmission component includes a first guide portion, a third transmission section disposed on the first guide portion, and a drive section disposed on the first guide portion. The cover body has a second guide portion that guides and cooperates with the first guide portion. The third transmission section is in transmission cooperation with the lower transmission component, and the drive section is drivenly connected to the rotating component. This allows the upper transmission component to move along the guiding directions of the first and second guide portions on the cover body, making the movement of the upper transmission component smoother and more reliable.

[0016] Furthermore, a fixed post is provided on the cover body, and a rotating component is rotatably mounted on the fixed post. An arc-shaped hole is also provided on the cover body. The first end of the rotating component has a drive elongated hole corresponding to the arc-shaped hole, and the second end of the rotating component has a driven elongated hole that engages with the upper transmission component. A drive post is provided on the first locking mechanism, passing through the arc-shaped hole and the drive elongated hole. The upper transmission component drives the rotating component to rotate through the driven elongated hole, causing the drive elongated hole to drive the drive post to rotate, thereby switching the first locking mechanism between a first unlocked position and a first locked position. And / or, the first locking mechanism includes a lock cover and a cover tooth provided on the bottom of the lock cover, the cover tooth being able to separate from or engage with the pot tooth. This allows the rotating component to rotate around the axis of the fixed post, making the rotation of the rotating component more stable. The upper transmission component extends into the driven elongated hole, causing the rotating component to rotate on the fixed post, causing the drive elongated hole to move and drive the drive post on the first locking mechanism passing through the drive elongated hole to rotate, thereby switching the first locking mechanism between a first unlocked position and a first locked position.

It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0042] To achieve the above objectives, this utility model provides a cooking utensil, comprising: a pot body, a lid, a rotating component 30, a second locking mechanism 40, an operating component 51, a lower transmission component 60, and an upper transmission component 70. The pot body is provided with a toothed part 951. The lid is placed on the pot body and includes a lid body 21 and a first locking mechanism 22 disposed below the lid body 21. The first locking mechanism 22 is rotatably disposed relative to the lid body 21 and has a first unlocking position separate from the toothed part 951 and a first locking position engaged with the toothed part 951. The rotating component 30 is rotatably disposed on the lid body 21. The second locking mechanism 40 is movably disposed on the pot body and has a second locking position locking the lid to the pot body and a second unlocking position unlocking the lid so that it can be opened from the pot body. The operating component 51 is movably disposed on the pot body and can rotate and move. The lower transmission component 60 is movably disposed on the pot body along the left-right direction. The upper transmission member 70 is movably mounted on the lid body 21 along the left-right direction of the pot body. The operating member 51 drives the rotating member 30 to rotate via a transmission engagement between the lower transmission member 60 and the upper transmission member 70. When the second locking mechanism 40 is in the second locked position, the rotation of the operating member 51 causes the lower transmission member 60 to move, which in turn drives the rotating member 30 to rotate via the upper transmission member 70, causing the rotating member 30 to switch the first locking mechanism 22 between the first unlocked position and the first locked position. When the first locking mechanism 22 is in the first unlocked position, the movement of the operating member 51 drives the second locking mechanism 40, causing the second locking mechanism 40 to switch from the second locked position to the second unlocked position.

[0043] like Figures 1 to 10As shown, applying the technical solution of this embodiment, the first locking mechanism 22 of the lid can engage with the pot teeth 951 of the pot body to be in the first locked position, and the second locking mechanism 40 can move to lock the lid onto the pot body and be in the second locked position, thus enabling a tighter connection between the pot body and the lid. When the user needs to open the lid, the user can rotate the operating member 51 to drive the rotating member 30 to rotate through the lower transmission member 60 and the upper transmission member 70, so that the first locking mechanism 22 switches from the first locked position to the first unlocked position. The user drives the operating member 51 to move, so that the second locking mechanism 40 switches to the second unlocked position, allowing the lid to be opened from the pot body. In this way, when the user opens the lid, the first locking mechanism 22 can be switched to the first unlocked position and the second locking mechanism 40 can be switched to the second unlocked position simply by rotating and moving the operating member 51. Thus, the user can open the lid simply by operating the operating member 51, without adjusting the operating position, reducing the steps required to operate back and forth between the pot body and the lid when opening the lid, making the operation convenient for the user. Therefore, the technical solution of this embodiment effectively solves the problem in related technologies that users need to operate back and forth between the pot body and the lid when opening the lid, which is a relatively complicated operation.

[0044] Furthermore, by applying the technical solution of this embodiment, the handle is avoided on the top surface of the lid, increasing the usable area of ​​the top surface of the lid. This facilitates the placement of the light panel and interactive interface on the top surface of the lid, enhances the area of ​​the interactive interface between the cooking appliance and the user, and improves the user's ease of operation and product experience.

[0045] In this embodiment, the cover is opened by rotating and moving the driving member 51. A single member 51 can perform two movements: switching the first locking mechanism 22 and switching the second locking mechanism 40. This improves the ease of opening the cover and enhances the user experience. The structure is simple and stable, with low production costs.

[0046] In this embodiment, when the second locking mechanism 40 is in the second locking position, the second locking mechanism 40 locks the lid onto the pot body in the vertical direction. At this time, the first locking mechanism 22 can rotate relative to the lid body 21.

[0047] like Figures 1 to 10 As shown, the cooking appliance also includes a gear transmission structure 80 mounted on the pot body. The operating member 51 engages with the lower transmission member 60 via the gear transmission structure 80 to drive the lower transmission member 60 to move. The gear transmission structure 80 has a simple and compact structure and reliable transmission. This configuration allows the operating member 51 to drive the lower transmission member 60 to move more stably and reliably via the gear transmission structure 80.

[0048] like Figures 8 to 10As shown, the gear transmission structure 80 includes a first gear 81 and a rack 82 that meshes with the first gear 81. Through the meshing of the first gear 81 and the rack 82, the rotational motion of the operating member 51 can be converted into linear motion, so that the operating member 51 can drive the lower transmission member 60 to move via the gear transmission structure 80. The first gear 81 is mounted on the operating member 51, and the rack 82 is mounted on the lower transmission member 60. This makes the gear transmission structure 80 more compact and easier to manufacture.

[0049] In other embodiments, the gear transmission structure 80 includes a first gear 81 and a rack 82 that meshes with the first gear 81. The rack 82 is disposed on the operating member 51, and the first gear 81 is disposed on the lower transmission member 60.

[0050] In other embodiments, the gear transmission structure 80 includes a second gear and a third gear that meshes with the second gear. One of the second and third gears is disposed on the operating member 51, and the other is disposed on the lower transmission member 60. Through the meshing of the second and third gears, the rotation of the operating member 51 can be transmitted to the lower transmission member 60, so that the lower transmission member 60 can be moved by the gear transmission structure 80. One end of the lower transmission member 60 is connected to the third gear, and the connection point between the lower transmission member 60 and the third gear has a predetermined distance from the rotation center of the third gear.

[0051] like Figures 5 to 8 As shown, the gear transmission structure 80 includes a first gear 81 and a rack 82 that meshes with the first gear 81. Through the meshing of the first gear 81 and the rack 82, the rotational motion of the operating member 51 can be converted into linear motion, so that the operating member 51 can drive the lower transmission member 60 to move via the gear transmission structure 80. The first gear 81 is fixedly mounted on the operating member 51 to ensure that the rotation of the operating member 51 can more stably and reliably drive the first gear 81 to rotate. The rack 82 is fixedly mounted on the lower transmission member 60 to ensure that the movement of the rack 82 can more stably and reliably drive the lower transmission member 60 to move. The operating member 51 can drive the second locking mechanism 40 via the first gear 81 and the rack 82, making the driving of the second locking mechanism 40 by the operating member 51 simpler and faster.

[0052] In this embodiment, the operating member 51 is disposed on the outside of the pot body, and the first gear 81 is fixedly disposed on the operating member 51 and located on the inside of the pot body. In this way, the first gear 81 can restrict the movement of the operating member 51 to the outside of the pot body, so that the setting of the operating member 51 on the pot body is more reliable, reducing the possibility of the operating member 51 falling off the pot body, reducing the use of fasteners, and facilitating installation.

[0053] In other embodiments, the gear transmission structure 80 includes a first gear 81 and a rack 82 that meshes with the first gear 81. The rack 82 is fixedly mounted on the operating member 51, and the first gear 81 is fixedly mounted on the lower transmission member 60. The operating member 51 can drive the second locking mechanism 40 via the first gear 81 or the rack 82.

[0054] like Figures 4 to 9 As shown, the operating element 51 is movably disposed on the pot body along the front-to-back direction to facilitate pressing operation of the operating element 51 by the user. The cooking appliance also includes an elastic element 52 disposed between the pot body and the operating element 51, which applies a restoring force to the operating element 51. The restoring force points from the rear of the pot body to the front of the pot body. The elastic element 52 facilitates the restoring of the operating element 51, allowing the operating element 51 to hold the second locking mechanism 40 in the second locked position or the second unlocked position when not subjected to force applied by the user.

[0055] It should be noted that the left-right direction of the pot refers to the direction from left to right when the cooking utensil is placed facing the user. The left side of the pot is on the user's left, and the right side is on the user's right. The front-back direction of the pot refers to the direction from front to back when the cooking utensil is placed facing the user. The side of the pot facing the user is the front, and the side away from the user is the back.

[0056] In this embodiment, when the operating member 51 is not subjected to force applied by the user, the second locking mechanism 40 remains in the second locked position. When the user presses the operating member 51 to move it and compress the elastic member 52, the second locking mechanism 40 switches from the second locked position to the second unlocked position. The elastic member 52 is a spring.

[0057] In this embodiment, a fixed base 53 is provided on the pot body, and the operating member 51 is movably and rotatably disposed within the fixed base 53. Both the operating member 51 and the elastic member 52 are disposed on the outer side of the fixed base 53. The elastic member 52 is disposed between the fixed base 53 and the operating member 51. A first gear 81 is disposed on the inner side of the fixed base 53 and is fixedly connected to the operating member 51. When the user presses the operating member 51, it can drive the first gear 81 to move inward together, thereby driving the second locking mechanism 40 to switch to the second unlocked position, so that the lid can be separated from the pot body. The operating member 51 is a knob.

[0058] In other embodiments, the operating element 51 is a knob, with its central shaft passing through the central hole of the first gear 81, and the central shaft of the knob and the central hole of the first gear 81 having a clearance fit. When the central shaft of the knob rotates, it can drive the first gear 81 to rotate together through the central hole. The central shaft of the knob passes through the central hole and can move relative to the central hole. The rear end of the central shaft passes through the central hole and pushes against the lower end of the second locking mechanism 40, so that the second locking mechanism 40 can swing, allowing the second locking mechanism 40 to switch between a second locked position and a second unlocked position.

[0059] like Figures 4 to 9 As shown, the lower transmission member 60 includes a lower transmission body and a lower coupling portion disposed on the lower transmission body. The lower transmission body is in transmission engagement with the operating member 51. The upper transmission member 70 includes an upper transmission body and an upper coupling portion disposed on the upper transmission body. The upper transmission body is drivenly connected to the rotating member 30, and the lower coupling portion is in transmission engagement with the upper coupling portion. Thus, when the operating member 51 rotates, it can drive the lower transmission body and the lower coupling portion to move, and the lower coupling portion drives the upper coupling portion on the upper transmission body to move, so that the upper transmission body can drive the rotating member 30 to rotate, which facilitates the switching of the first locking mechanism 22 between the first unlocked position and the first locked position. The arrangement of the lower coupling portion and the upper coupling portion facilitates the synchronous movement of the upper transmission member 70 and the lower transmission member 60.

[0060] like Figures 1 to 8 As shown, the lower coupling part is a coupling groove 61, and the upper coupling part is a coupling block 71 inserted into the coupling groove 61. The coupling groove 61 and the coupling block 71 have a simple structure and reliable transmission. This makes the synchronous movement of the upper transmission component 70 and the lower transmission component 60 more stable and reliable.

[0061] In this embodiment, the coupling groove 61 is a recessed groove provided on the top surface of the lower transmission body. When the cover is placed on the pot body, the coupling block 71 can be inserted into the coupling groove 61.

[0062] In other embodiments, the upper coupling part is a coupling groove 61, and the lower coupling part is a coupling block 71 inserted into the coupling groove 61.

[0063] like Figures 4 to 9As shown, the lower transmission member 60 includes a first transmission section 62 that engages with the operating member 51 and a second transmission section 63 that engages with the upper transmission member 70. A support boss 11 is provided on the pot body to support the second transmission section 63. The support boss 11 supports the second transmission section 63, making its movement smoother and more reliable, and allowing it to be more stably and reliably mounted on the pot body. The lower transmission member 60 also includes a connecting section 64 connecting the first transmission section 62 and the second transmission section 63. The support boss 11 has a clearance hole 12 to avoid the connecting section 64. The connecting section 64 makes the connection between the first transmission section 62 and the second transmission section 63 more reliable. The clearance hole 12 avoids the connecting section 64, facilitating the movement of the lower transmission member 60. The first transmission section 62, the second transmission section 63, and the connecting section 64 facilitate the installation of the lower transmission member 60 on the pot body.

[0064] In this embodiment, the support boss 11 is located below the second transmission section 63, and the support boss 11 can restrict the downward movement of the second transmission section 63. The support boss 11 is located above the first transmission section 62, and the support boss 11 can restrict the upward movement of the first transmission section 62.

[0065] In this embodiment, the pot body includes an outer pot and an inner pot 96 disposed inside the outer pot. The outer pot includes a shell 91 and a middle plate 92 disposed on the top of the shell 91. The first transmission segment 62 is located below the middle plate 92. A connecting seat 65 is provided on the first transmission segment 62, and a connecting segment 64 is inserted into the connecting seat 65 and fixedly connected by screws, pins, or fasteners to fix the first transmission segment 62 and the second transmission segment 63. The connecting seat 65 is disposed on the top surface of the first transmission segment 62, and the rack 82 is disposed on the bottom surface of the first transmission segment 62. A guide hole 621 is provided on the first transmission segment 62, and a guide post 921 that guides and engages with the guide hole 621 is provided on the middle plate 92 to allow the first transmission segment 62 to move along the extension direction of the guide hole 621.

[0066] like Figures 4 to 9As shown, the upper transmission member 70 includes a first guide portion 72, a third transmission section 73 disposed on the first guide portion 72, and a drive section 74 disposed on the first guide portion 72. A second guide portion 211 is provided on the cover body 21 to guide and cooperate with the first guide portion 72. This allows the upper transmission member 70 to move along the guiding directions of the first guide portion 72 and the second guide portion 211 on the cover body 21, making the movement of the upper transmission member 70 smoother and more reliable. The third transmission section 73 is driven to cooperate with the lower transmission member 60, and the drive section 74 is driven to connect with the rotating member 30. This allows the lower transmission member 60 to move when it moves, driving the third transmission section 73 of the upper transmission member 70, so that the drive section 74 drives the rotating member 30 to rotate under the guidance of the first guide portion 72 and the second guide portion 211.

[0067] In this embodiment, the second guide portion 211 is a guide groove, and the first guide portion 72 is a guide block movably disposed within the guide groove, with the guide block engaging with the side wall of the guide groove. The drive section 74 is located above the first guide portion 72, and the third transmission section 73 is located below the first guide portion 72.

[0068] like Figures 4 to 9 As shown, a fixed post 212 is provided on the cover body 21, and a rotating member 30 is rotatably mounted on the fixed post 212. An arc-shaped hole 213 is also provided on the cover body 21. A driving elongated hole 31 corresponding to the arc-shaped hole 213 is provided at the first end of the rotating member 30, and a driven elongated hole 32 that drives and cooperates with the upper transmission member 70 is provided at the second end of the rotating member 30. A driving post 223 is provided on the first locking mechanism 22, passing through the arc-shaped hole 213 and the driving elongated hole 31. The upper transmission member 70 drives the rotating member 30 to rotate through the driven elongated hole 32, causing the driving elongated hole 31 to drive the driving post 223 to rotate, thereby switching the first locking mechanism 22 between a first unlocked position and a first locked position. This allows the rotating member 30 to rotate around the axis of the fixed post 212, making the rotation of the rotating member 30 more stable. The upper transmission member 70 extends into the driven elongated hole 32, causing the rotating member 30 to rotate on the fixed post 212. This causes the driving elongated hole 31 to move, driving the driving post 223 of the first locking mechanism 22, which passes through the driving elongated hole 31, to rotate, thereby switching the first locking mechanism 22 between the first unlocked position and the first locked position. The arc-shaped hole 213 allows the driving post 223 of the first locking mechanism 22 to pass through the arc-shaped hole 213 and extend into the driving elongated hole 31, so that the driving elongated hole 31 can drive the driving post 223 to rotate when it moves. The arc-shaped hole 213 can avoid the rotation of the driving post 223. The first locking mechanism 22 includes a lock cover 221 and a cover tooth 222 provided on the bottom of the lock cover 221. The cover tooth 222 can be separated from or engaged with the pot tooth 951. The first locking mechanism 22 has a simple structure and is easy to manufacture. The cover tooth 222 engages tightly with the pot tooth 951.

[0069] In this embodiment, the drive post 223 is disposed on the lock cover 221. The user rotates the operating member 51 to drive the drive post 223 to rotate, thereby causing the lock cover 221 to rotate, so that the cover teeth 222 on the lock cover 221 can rotate to separate from or engage with the pot teeth 951. The user drives the operating member 51 to switch the second locking mechanism 40 from the second locked position to the second unlocked position, so that the cover can be opened.

[0070] In this embodiment, the pot body includes an outer pot and an inner pot 96 disposed within the outer pot. The outer pot includes a shell 91, a middle plate 92 disposed on the top of the shell 91, and a pressure-bearing ring 95 disposed above the middle plate 92. The inner pot 96 is placed within the pressure-bearing ring 95, and pot teeth 951 are disposed on the pressure-bearing ring 95. Alternatively, pot teeth 951 are disposed on either the outer pot or the inner pot 96. The outer pot includes a shell 91 and a heat-insulating cover disposed within the shell 91, and pot teeth 951 are disposed on the heat-insulating cover. The pot body can only be heated when the first locking mechanism 22 is in the first locking position and the second locking mechanism 40 is in the second locking position, so as to increase the pressure within the cooking space inside the pot.

[0071] The pot edge in this application can be the pot rim, a raised edge, or an outward-flared edge.

[0072] In this embodiment, the fixing seat 53 is installed on the outer shell 91, and then the first gear 81 and the elastic element 52 are installed on the fixing seat 53. The outer shell 91 is then installed on the middle plate 92. After the outer shell 91 is installed on the middle plate 92, the first gear 81 is located below the rack 82 and meshes with the rack 82. The second locking mechanism 40 is swayably installed on the middle plate 92. The second locking mechanism 40 is a fastening plate, and rotating shafts are provided on both sides of the fastening plate. The rotating shafts are rotatably mounted on the middle plate 92. A return spring is provided at one end of the fastening plate to keep the fastening plate in the second locked position. The bottom of the cover body is provided with a buckle that engages or disengages with the fastening plate. When the fastening plate engages with the buckle, the second locking mechanism 40 is in the second locked position; when the fastening plate disengages from the buckle, the second locking mechanism 40 is in the second unlocked position.

[0073] The cooking appliance also includes a base 94 and a heating element 93 disposed below a middle plate 92. The base 94 is fixedly disposed below the outer casing 91, and the middle plate 92 is disposed above the outer casing 91, so as to fix the outer casing 91 between the base 94 and the middle plate 92. This allows the mounting bracket 53 on the outer casing 91 to be fixed, and reduces the vertical displacement of the operating member 51 and the first gear 81 on the mounting bracket 53.

[0074] In this embodiment, when the lid and pot body need to be fastened and locked, the clockwise rotation of the operating component 51 drives the first gear 81 to rotate. The first gear 81 meshes with the rack 82 and drives the first transmission section 62 to move to the right. The first transmission section 62 pulls the second transmission section 63 to move to the right as well. The second transmission section 63 drives the upper transmission component 70 to move to the right in sync, thereby driving the rotating component 30 to rotate counterclockwise, which in turn drives the locking cover 221 to rotate clockwise to the first locking position where it engages with the pot teeth 951.

[0075] In this embodiment, when the lid needs to be separated from the pot body, the operating member 51 is rotated counterclockwise, and the second transmission section 63 and the upper transmission member 70 move to the left, rotating the lid teeth 222 on the locking lid 221 counterclockwise to the position where they are separated from the pot teeth 951. At this time, the driving operating member 51 moves inward to switch the second locking mechanism 40 to the second unlocking position. A pivot and a torsion spring are provided between the lid and the pot body to realize the automatic opening of both (i.e., the fastening plate automatically separates from the snap fastener). The lid is pivotally mounted on the pot body and connected to the pot body by the torsion spring.

[0076] In other embodiments, a fixed post 212 is provided on the cover body 21, and a rotating member 30 is rotatably mounted on the fixed post 212. The cover body 21 also has an arc-shaped hole 213. The first end of the rotating member 30 has a driving elongated hole 31 corresponding to the arc-shaped hole 213, and the second end of the rotating member 30 has a driven elongated hole 32 that drives and cooperates with the upper transmission member 70. The first locking mechanism 22 has a driving post 223 passing through the arc-shaped hole 213 and the driving elongated hole 31. The upper transmission member 70 drives the rotating member 30 to rotate through the driven elongated hole 32, so that the driving elongated hole 31 drives the driving post 223 to rotate, thereby switching the first locking mechanism 22 between a first unlocked position and a first locked position. Alternatively, the first locking mechanism 22 includes a lock cover 221 and a cover tooth 222 provided on the bottom of the lock cover 221. The cover tooth 222 can be separated from or engaged with the pot tooth 951.

[0077] In this embodiment, the lower transmission member 60 is movably disposed along the left-right direction of the pot body, and the rotating member 30 can be driven to rotate through the transmission engagement of the lower transmission member 60 and the upper transmission member 70. The lower transmission member 60 has a first transmission position and a second transmission position. When the lower transmission member 60 is in the first transmission position, the transmission engagement of the lower transmission member 60 and the upper transmission member 70 causes the first locking mechanism 22 to be in the first unlocked position via the rotating member 30. When the lower transmission member 60 is in the second transmission position, the transmission engagement of the lower transmission member 60 and the upper transmission member 70 causes the first locking mechanism 22 to be in the first locked position via the rotating member 30.

[0078] The cooking appliance also includes a self-locking member 100 movably mounted vertically on the pot body, having a clearance position for allowing the lower transmission member 60 to move and a self-locking position for locking the lower transmission member 60 in a first transmission position. When the second locking mechanism 40 is in the second locked position, and the lid pushes the self-locking member 100 downward and places it in the clearance position, the lower transmission member 60 switches between the first transmission position and the second transmission position, causing the rotating member 30 to drive the first locking mechanism 22 to switch between the first unlocked position and the first locked position. When the second locking mechanism 40 is in the second unlocked position and the lower transmission member 60 is in the first transmission position, the lid clears the self-locking member, causing the self-locking member to move upward and be in the self-locking position.

[0079] Thus, when the second locking mechanism 40 is in the second unlocked position, the lid can separate from the pot. When the lid is opened, the lid avoids the self-locking member 100, and the self-locking member 100 switches to the self-locking position, thereby locking the lower transmission member 60 in the first transmission position and keeping the first locking mechanism 22 in the first unlocked position, so as to facilitate the transmission cooperation between the lower transmission member 60 and the upper transmission member 70 when the lid is closed. When the lid is placed on the pot, the second locking mechanism 40 is driven to the second locked position, and the lid drives the self-locking member 100 to switch to the avoidance position, so that the lower transmission member 60 can move and drive the first locking mechanism 22 to switch to the first locked position, so as to facilitate the fastening and locking of the lid and the pot.

[0080] like Figures 1 to 10 As shown, the lower transmission member 60 is provided with a limiting hole 633. The self-locking member 100 includes a pressure-receiving post 101 and a limiting post 102. The pressure-receiving post 101 can engage with the cover, and the limiting post 102 can engage with the limiting hole 633. When the cover is in the second locked position, the cover pushes the pressure-receiving post 101 downward, and the limiting post 102 disengages from the limiting hole 633, so that the self-locking member 100 is in a clearance position. When the first locking mechanism 22 is in the second unlocked position, the cover avoids the pressure-receiving post 101, and the limiting post 102 moves upward to engage with the limiting hole 633, so that the self-locking member 100 is in a self-locking position. The self-locking member 100 has a simple structure and is easy to manufacture. The pressure-receiving post 101 facilitates engagement with the cover's drive, allowing the self-locking member 100 to move vertically. The limiting post 102 is designed to be easily inserted into the limiting hole 633 so that the self-locking member 100 can be limited and engaged with the lower transmission member 60; it also makes it easy for the limiting post 102 to disengage from the limiting hole 633 when the self-locking member 100 moves in the vertical direction, so as to facilitate the movement of the lower transmission member 60.

[0081] The height of the pressure-bearing column 101 is greater than or equal to the height of the limiting hole 633. The height of the limiting column 102 is less than or equal to the height of the limiting hole 633. This facilitates contact between the pressure-bearing column 101 and the lid when the lid is placed on the pot body, allowing the lid to push the pressure-bearing column 101 downwards and easily disengage from the limiting hole 633, thus facilitating the movement of the lower transmission member 60 between the first and second transmission positions. Furthermore, when the lid is opened from the pot body, the limiting column 102 passes through the limiting hole 633 without protruding from it, resulting in a simpler and more compact structure and preventing accidental contact with the limiting column 102.

[0082] The cooking appliance also includes a mounting base 110 and a resilient reset member disposed within the pot body. The mounting base 110 is located below the middle plate 92. A self-locking member 100 passes through the mounting base, and the resilient reset member is disposed between the mounting base 110 and the self-locking member 100. The resilient reset member applies a reset force to the self-locking member 100 to keep it in the self-locked position. The mounting base 110 facilitates the vertically movable installation of the self-locking member 100 on the pot body. The resilient reset member has a simple structure, effectively holding the self-locking member 100 in the self-locked position, and can also be compressed when the lid pushes the pressure column 101 downward to prevent movement of the lower transmission member 60.

[0083] The support boss 11 includes a support plane 111 and a support ramp 112. A self-locking member 100 passes through the support plane 111, and a clearance hole 12 is provided on the support ramp 112. The second transmission section 63 includes a sliding plate 631 that overlaps the support plane 111 and a sliding block 632 that overlaps the support ramp 112. A connecting section 64 is connected to the sliding block 632. This makes the sliding of the sliding plate 631 on the support plane 111 more stable and reliable. Providing the clearance hole 12 on the support ramp 112 can avoid the movement of the connecting section 64, so as to facilitate the transmission cooperation between the second transmission section 63 and the upper transmission member 70. Furthermore, the above arrangement can form a guide rail to guide the second transmission section 63, so that the movement of the second transmission section 63 is more stable.

[0084] The cooking appliance in this embodiment is an electric pressure cooker. Of course, in embodiments not shown in the figures, the pot body can also be a cup or an inner pot. The cooking appliance can also be a rice cooker, a low-pressure rice cooker, a soy milk maker, a food processor, a stir-fry machine, an electric slow cooker, a multi-functional pot, etc.

[0085] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model.
