Description

[0001] This application claims priority to the invention patent application filed on December 29, 2023, with application number 202311873884.7, entitled "Cooking Utensils". Technical Field

[0002] This utility model relates to the field of small household appliances, and more specifically, to a fastening component and a cooking utensil having the same. Background Technology

[0003] In related technologies, cooking appliances include a pot body and a lid. To ensure the lid can be stably attached to the pot body, a double locking structure is provided between the lid and the pot body. The first locking structure is a locking mechanism formed by the locking teeth on the lid and the pot body inside the pot body through the lid teeth and pot teeth; the second locking structure is a locking mechanism formed by the locking plate on the lid and the hook on the pot body.

[0004] The first locking mechanism requires rotating the handle on the lid to unlock, while the second locking mechanism requires pressing a button on the pot body. Therefore, when a user needs to open the lid, they must first rotate the handle and then press the button to unlock, which is rather complicated and results in a poor user experience.

[0005] In related technologies, Chinese utility model patent application number 202221673921.0 provides a cooking appliance that solves the problem of complicated operation when opening the lid. This patent includes a lid-opening button, a drive lever, a transmission lever, a transmission plate, and a clamping structure. By pressing the lid-opening button, the button applies force to the drive lever, causing the hook of the drive lever to separate from the lid's locking mechanism. The hook of the drive lever no longer restricts the transmission lever, allowing the transmission rod to move forward. The clamping structure then switches to the unlocked state, achieving dual unlocking with just the press of the lid-opening button, simplifying the user's operation.

[0006] However, in actual use, the above-mentioned patented solution may have problems such as difficulty in opening the lid due to the need for force during the opening process, or even the inability to open the lid at all. Utility Model Content

[0007] The main purpose of this utility model is to provide a fastening component and a cooking appliance having the same, so as to solve the problem in the related art that the lid is difficult to open due to the difficulty of pressing during the opening process, or even cannot be opened at all.

[0008] To achieve the above objectives, according to one aspect of the present invention, a fastening assembly is provided, comprising: a first hook, rotatably disposed and having an independent rotation state and a linked rotation state, the first hook including a first hook body; a second hook, rotatably disposed and adjacent to the first hook, the second hook including a second hook body; and a linkage structure disposed between the first hook body and the second hook body, wherein, when the first hook is in the independent rotation state, the second hook is stationary, and the first hook rotates relative to the second hook; when the first hook is in the linked rotation state, the first hook drives the second hook to rotate together through the linkage structure.

[0009] By applying the technical solution of this utility model, the fastening component is set on the pot body and cooperates with the locking platform of the lid assembly and the rotating part of the transmission mechanism to achieve double locking and unlocking between the pot body and the lid assembly. Specifically, when the first hook and the second hook are stationary, the second hook is engaged with the locking platform, and the first hook abuts against the rotating part and pulls the linkage to keep the locking mechanism in the locked state. At this time, the lid assembly and the pot body are double locked, and the cooking appliance can perform pressure cooking in this state. During the process from double locking to unlocking, the first hook drives the rotating part to rotate, or the rotating part drives the first hook to rotate. At this time, the second hook remains engaged with the locking platform, and the first hook continues to rotate, thereby driving the second hook to move together through the linkage structure, and the fastening component switches to the unlocked state. When the fastening component is in the unlocked state, the second hook separates from the locking platform, the locking mechanism is in the unlocked state, and the lid assembly and the pot body are unlocked. At this time, the lid assembly will switch from the closed state to the open state. In existing technologies, for solutions where the fastening assembly, locking platform, and locking mechanism work together, the lid assembly moves upwards during the locking mechanism's movement. This makes the locking mechanism susceptible to interference from other structures during unlocking, resulting in laborious operation and difficulty in opening the lid. In the process from double locking to unlocking, when the first hook drives the rotating component to rotate, or the rotating component drives the first hook to rotate, the second hook remains engaged with the locking platform. At this time, the position of the lid assembly relative to the pot body remains unchanged. The rotation of the rotating component switches the locking mechanism from the locked state to the unlocked state. This prevents interference between the locking mechanism and other structures within the lid assembly during movement, improving smoothness and making the lid assembly open and close more smoothly. Therefore, the technical solution of this invention solves the problems of laborious lid opening and difficulty in opening the lid in related technologies. By setting a linkage structure between the first and second hooks, the first hook drives the second hook to rotate together through the linkage structure, thereby achieving the state switching of the fastening assembly.

[0010] Furthermore, the first hook also includes a first rotating plate, with the first hook body disposed at the end of the first rotating plate. The second hook also includes a second rotating plate, with the second hook body disposed at the end of the second rotating plate. A clearance space exists between the first hook body and the second hook body, so that when the first hook rotates relative to the second hook, the second hook body avoids the first hook body. This structure enables independent rotation of the first hook relative to the second hook, as well as synchronous movement between the two. It is simple in structure, easy to implement, and its motion is easily controlled.

[0011] Furthermore, the linkage structure includes a first abutting surface on the first hook body and a second abutting surface on the second hook body. When the first hook is in the linkage rotation state, the first abutting surface abuts against the second abutting surface, so that the first hook drives the second hook to rotate together. The above structure is simple and the movement process is easy to control.

[0012] Furthermore, when the first and second abutting surfaces are in contact and the second hook is stationary, the first abutting surface is a first vertical surface, and the second abutting surface is a second vertical surface. This structure allows the first hook to rotate while the second hook rotates, with the two hooks contacting each other through vertical surfaces, thus improving the controllability of the movement stroke and enhancing movement stability.

[0013] Furthermore, the first abutting surface is located on the inner wall of the first hook body. The above structure is simple and easy to implement.

[0014] Furthermore, the second hook body includes a snap-fit ​​hook body and a stop hook body disposed on at least one side of the snap-fit ​​hook body, the snap-fit ​​hook body protruding from the stop hook body, and the second stop surface disposed on the stop hook body. The above structure is easy to manufacture and has a good fit.

[0015] Furthermore, when the first hook is in the linked rotation state, the lowest point of the first hook body is higher than or level with the lowest point of the second hook body. The above structure can ensure that during the process of switching the pot body and lid body assembly from the unlocked state to the double-locked state, both the first hook body and the second hook body can be engaged with the locking platform and locked into place.

[0016] Furthermore, the first rotating plate includes a plate body and flanges disposed on both sides of the plate body. A first rotating connecting portion is provided on the flange, and an accommodating space is formed between the plate body and the flanges. The second rotating plate is located within the accommodating space, and a second rotating connecting portion is provided on the second rotating plate. A first notch corresponding to the second rotating connecting portion is also provided on the flange. This structure allows the second hook to be housed inside the first hook, thus making the overall structure of the fastening assembly more compact.

[0017] Furthermore, the first hook is positioned above the second hook, and a second notch is provided on the first hook, with the end of the second hook located within the second notch. This second notch allows the first hook to avoid the second hook when the first hook is rotating independently, preventing the first hook from prematurely rotating the second hook. The second notch also allows for a smaller size of the first hook, resulting in a more compact structure for the fastening assembly.

[0018] According to another aspect of the present invention, a cooking appliance is provided, comprising: a pot body; a lid assembly, which is closably disposed on the pot body, the rear part of the lid assembly being hinged to the pot body, and the front part of the lid assembly having a locking platform, the lid assembly having an open state and a closed state; a locking mechanism, which is movably disposed on the lid assembly and has a locked state for locking the pot body and an unlocked state for unlocking the pot body; a fastening assembly, which is rotatably disposed on the pot body, and the fastening assembly is the fastening assembly described above; and a transmission mechanism, comprising a rotating member rotatably disposed on the lid assembly and a linkage member disposed between the rotating member and the locking mechanism; wherein, when the first hook and the second hook of the fastening assembly are stationary, the second hook is engaged with the locking platform, the first hook abuts against the rotating member and pulls the linkage member to keep the locking mechanism in the locked state, when the first hook and the rotating member rotate, the second hook remains engaged with the locking platform, and the fastening assembly continues to rotate and switches to the unlocked state.

[0019] By applying the technical solution of this utility model, since the fastening component can solve the problems of laborious opening operation and unsmooth opening in related technologies, cooking utensils including the fastening component can also solve the above problems.

Therefore, other examples of exemplary embodiments may have different values. 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.

[0066] The technical solution of this application can solve the above problems. The solution of this application will now be described in detail with reference to the accompanying drawings.

[0067] like Figures 13 to 16 As shown, the fastening assembly of this embodiment includes a first hook 41, a second hook 42, and a linkage structure. The first hook 41 is rotatably disposed and has an independent rotation state and a linked rotation state. The first hook 41 includes a first hook body 412. The second hook 42 is rotatably disposed adjacent to the first hook 41 and includes a second hook body 422. The linkage structure is disposed between the first hook body 412 and the second hook body 422. When the first hook 41 is in the independent rotation state, the second hook 42 is stationary, and the first hook 41 rotates relative to the second hook 42. When the first hook 41 is in the linked rotation state, the first hook 41 drives the second hook 42 to rotate together through the linkage structure.

[0068] Applying the technical solution of this embodiment, the fastening component is disposed on the pot body 10 and cooperates with the locking platform 21a of the lid assembly 20 and the rotating member 51 of the transmission mechanism 50, thereby achieving double locking and unlocking between the pot body 10 and the lid assembly 20. Specifically, when the first hook 41 and the second hook 42 are stationary, the second hook 42 is engaged with the locking platform 21a, and the first hook 41 abuts against the rotating member 51 and pulls the linkage member 52 to keep the locking mechanism 30 in the locked state. At this time, the lid assembly 20 and the pot body 10 are double locked, and the cooking appliance can perform pressure cooking in this state. During the process from double locking to unlocking, the first hook 41 drives the rotating member 51 to rotate, or the rotating member 51 drives the first hook 41 to rotate. At this time, the second hook 42 remains engaged with the locking platform 21a. Afterward, the first hook 41 continues to rotate, and then the first hook 41 drives the second hook 42 to move together through the linkage structure, thereby switching the fastening component 40 to the unlocked state. When the fastening assembly 40 is in the unlocked state, the second hook 42 separates from the locking platform 21a, the locking mechanism 30 is in the unlocked state, and the lid assembly 20 and the pot body 10 are unlocked. At this time, the lid assembly 20 will switch from the closed state to the open state. In the prior art, for the scheme in which the fastening assembly, the locking platform, and the locking mechanism work together simultaneously, the lid assembly will move upward during the movement of the locking mechanism. This makes the locking mechanism susceptible to interference from other structures during the unlocking process, resulting in difficult operation and unsmooth opening of the lid. During the process from double locking to unlocking, when the first hook 41 drives the rotating member 51 to rotate or the rotating member 51 drives the first hook 41 to rotate, the second hook 42 remains engaged with the locking platform 21a. At this time, the position of the lid assembly 20 relative to the pot body 10 remains unchanged. The rotating member 51 continues to rotate, causing the locking mechanism 30 to switch from the locked state to the unlocked state. In this way, the locking mechanism 30 will not interfere with other structures inside the lid assembly 20 during movement, improving the smoothness of movement, and thus making the lid assembly 20 open or close more smoothly. Therefore, the technical solution of this embodiment can solve the problems of laborious opening operation and unsmooth opening in related technologies. By setting a linkage structure between the first hook body and the second hook body, the first hook 41 drives the second hook 42 to rotate together through the linkage structure, so as to realize the state switching of the fastening component.

[0069] In this embodiment, as Figures 13 to 16As shown, the first hook 41 further includes a first rotating plate 411, and a first hook body 412 is disposed at the end of the first rotating plate 411. The second hook 42 further includes a second rotating plate 421, and a second hook body 422 is disposed at the end of the second rotating plate 421. A clearance space 46 exists between the first hook body 412 and the second hook body 422, so that when the first hook 41 rotates relative to the second hook 42, the second hook body 422 avoids the first hook body 412. This structure enables the independent rotation of the first hook 41 relative to the second hook 42, as well as synchronous movement between the two. The structure is simple, easy to implement, and the motion state is easy to control. Because of the clearance space 46, the second hook 42 can remain stationary, while the first hook 41 can rotate independently relative to the second hook 42. The first hook 41 is... Figure 2d The state is rotated to Figure 3d The state.

[0070] In this embodiment, the first rotating plate 411 and the second rotating plate 421 are stacked, with the second rotating plate 421 located on one side of the first rotating plate 411 in the thickness direction. When the first hook body 412 of the first hook 41 rotates to engage with the second hook body 422 of the second hook 42, the first hook body 412 drives the second hook body 422 to rotate outward together (towards a direction away from the longitudinal axis of the cooking utensil). The first hook 41 and the second hook 42 are... Figure 3d The state is rotated to Figure 4d The state.

[0071] like Figure 16 and Figure 21 As shown, the linkage structure includes a first abutting surface 414 disposed on the first hook body 412 and a second abutting surface 424 disposed on the second hook body 422. When the first hook 41 is in the linkage rotation state, the first abutting surface 414 abuts against the second abutting surface 424, so that the first hook 41 drives the second hook 42 to rotate together. The above structure is simple and the movement process is easy to control.

[0072] In other embodiments not shown in the figure, the first hook can drive the second hook to move in other ways, such as by setting a linkage between the two, such as a lever, a rope, or an elastic element. In this case, the first hook can also drive the second hook to rotate together.

[0073] like Figure 16 and Figure 21 As shown, when the first abutment surface 414 and the second abutment surface 424 are in contact and the second hook 42 is in a stationary state, the first abutment surface 414 is the first vertical surface and the second abutment surface 424 is the second vertical surface. This structure allows the first hook 41 to rotate together with the second hook 42 through vertical surface contact, improving the controllability of the movement stroke and enhancing movement stability.

[0074] like Figure 16 and Figure 21 As shown, the first abutting surface 414 is disposed on the inner wall of the first hook body 412. The above structure is simple and easy to implement.

[0075] like Figure 16 As shown, the second hook 422 includes a snap-fit ​​hook 4221 and abutting hooks 4222 disposed on both sides of the snap-fit ​​hook 4221. The snap-fit ​​hook 4221 protrudes from the abutting hooks 4222, and a second abutting surface 424 is disposed on the abutting hook 4222. The above structure is easy to process and has a good fit.

[0076] like Figure 20 and Figure 22 As shown, when the first hook 41 is in the linkage rotation state, the lowest point of the first hook 412 is higher than or level with the lowest point of the second hook 422. This structure ensures that during the transition from the unlocked state to the double-locked state between the pot body 10 and the lid assembly 20, both the first hook 412 and the second hook 422 can engage with and be properly engaged with the locking platform 21a. This avoids interference during the reset process, preventing them from engaging properly.

[0077] like Figure 13 and Figure 15 As shown, the first hook 412 is located above the second hook 422. The first hook 412 has a second notch 4121, and the end of the second hook 422 is located within the second notch 4121. The second notch 4121 allows the first hook 412 to avoid the second hook 422 when it is rotating independently, preventing the first hook 412 from prematurely rotating the second hook 422. The second notch 4121 also makes the first hook 412 smaller, resulting in a more compact structure for the fastening assembly.

[0078] In this embodiment, the end of the second hook 422's engaging hook 4221 is located within the second notch 4121, abutting against the inner wall of the first hook 412. Alternatively, as a feasible implementation, the entire end of the second hook could be located within the second notch 4121.

[0079] Of course, as a feasible implementation, when the first hook is in the linked rotation state, the lowest point of the first hook body can also be higher than the lowest point of the second hook body. This can also achieve the locking of the first hook body and the second hook body into place during the reset process.

[0080] The first hook 412 has a first protruding dimension L1 protruding from the first rotating plate 411, and the second hook 422 has a second protruding dimension L2 protruding from the second rotating plate 421, wherein the first protruding dimension L1 and the second protruding dimension L2 satisfy L1 ≥ 1.5L2. This structure ensures the rotation of the first hook 41 relative to the second hook 42, thereby ensuring the locking stability of the locking mechanism 30 driven by the first hook 41. Preferably, L1 = 1.5L2, or L1 = 2L, or L1 = 2.5L2.

[0081] like Figure 15 As shown, the first rotating plate 411 includes a plate body 4111 and flanges 4112 disposed on both sides of the plate body 4111. A first rotating connecting portion 4113 is provided on the flanges 4112. A receiving space is formed between the plate body 4111 and the flanges 4112. The second rotating plate 421 is located within the receiving space. The second rotating plate 421 is provided with a second rotating connecting portion 4213. A first notch 4114 corresponding to the second rotating connecting portion 4213 is also provided on the flanges 4112. This structure allows the second hook 42 to be housed inside the first hook 41, making the overall structure of the fastening assembly more compact. The first rotating connecting portion 4113 and the second rotating connecting portion 4213 can be a pin or a shaft hole. The plate body 4111 is provided with a clearance portion for avoiding other components, such as a pushing component.

[0082] The pot body 10 of the cooking appliance includes a middle plate 12 and a base connected to the middle plate 12, such as Figure 23 and Figure 24 As shown, the fastening assembly 40 is mounted on the middle plate. Specifically, the first rotating connecting part 4113 of the first hook 41 is connected in the first mounting hole 121, and the second rotating connecting part 4213 of the second hook 42 is provided with a pin through the second mounting hole 122 to achieve a rotating connection.

[0083] like Figure 15 and Figure 16 As shown, a first reset member connecting portion 4115 is provided on the first rotating plate 411, and a second reset member connecting portion 4215 is provided on the second rotating plate 421. This structure facilitates the connection of the reset members. The first reset member connecting portion 4115 includes two connecting shafts extending outward in opposite directions, and the second reset member connecting portion 4215 includes two connecting shafts extending inward in opposite directions.

[0084] like Figure 15 and Figure 16As shown, the first rotating plate is further provided with a first reset member positioning part 4116, and the second rotating plate is provided with a second reset member positioning part 4216. The above structure is used to position the reset member, ensuring its normal operation. In this embodiment, the first reset member positioning part 4116 is a first positioning rib, and the second reset member positioning part 4216 is a second positioning rib. Of course, a first positioning groove can also be provided near the first positioning rib, and a second positioning groove can also be provided near the second positioning rib.

[0085] like Figure 15 and Figure 16 As shown, the first rotating plate 411 has a first limiting surface 413 located below the first hook body 412, and the second rotating plate 421 has a second limiting surface 423 located below the second hook body 422. The first limiting surface 413 and the second limiting surface 423 are flush. When the first hook 41 and the second hook 42 are in a stationary state, the first limiting surface 413 of the first hook 41 abuts against the vertical plate 212, and the second limiting surface 423 of the second hook 42 abuts against the vertical plate 212. The aforementioned first limiting surface 413 and the second limiting surface 423 can respectively limit the position of the first hook 41 and the second hook 42, so that both are engaged with the fastening plane 21b.

[0086] like Figure 1 As shown, the cooking appliance also includes a first reset member 44 disposed between the pot body 10 and the first hook 41, and a second reset member 45 disposed between the pot body 10 and the second hook 42. The first reset member 44 enables the first hook 41 to remain in a vertical position, and the second reset member 45 enables the second hook 42 to remain in a vertical position. When the lid assembly 20 is in the closed position, the first hook 41 abuts against the rotating member 51 under the elastic force of the first reset member 44, and the second hook 42 is engaged with the retaining plate 21a under the elastic force of the second reset member 45. Both the first reset member 44 and the second reset member 45 are torsion springs. The first limiting surface 413 of the first hook 41 can abut against the vertical plate 212 of the retaining plate 21a or the vertical plate on the pot body 10 located below the vertical plate 212, thus keeping the first hook 41 in a vertical position. Similarly, the second limiting surface 423 of the second hook 42 can abut against the vertical plate 212 of the mounting plate 21a or the vertical plate on the pot body 10 located below the vertical plate 212, thereby keeping the second hook 42 in a vertical position. When the first rotating plate 411 and the second rotating plate 421 are in contact, the first limiting surface 413 and the second limiting surface 423 are coplanar.

[0087] According to another aspect of the present invention, a cooking utensil is provided, such as Figure 1 As shown, the cooking appliance of Embodiment 1 includes: a pot body 10, a lid assembly 20, a locking mechanism 30, a fastening assembly 40, and a transmission mechanism 50.

[0088] The lid assembly 20 is closably mounted on the pot body 10. The rear part of the lid assembly 20 is hinged to the pot body 10. The front part of the lid assembly 20 is provided with a locking part 21a. The lid assembly 20 has an open state and a closed state.

[0089] The locking mechanism 30 is movably disposed on the lid assembly 20 and has a locked state for locking the pot body 10 and an unlocked state for unlocking the pot body 10.

[0090] The fastening component 40 is rotatably mounted on the pot body 10, and the fastening component is the fastening component described above.

[0091] The transmission mechanism 50 includes a rotating member 51 (also known as a swing rod) rotatably mounted on the cover assembly 20 and a linkage member 52 disposed between the rotating member 51 and the locking mechanism 30. The fastening assembly 40 can drive the rotating member 51 to rotate.

[0092] When the first hook 41 and the second hook 42 of the fastening assembly 40 are stationary, the second hook 42 is engaged with the locking platform 21a, the first hook 41 abuts against the rotating member 51 and pulls the linkage member 52 to keep the locking mechanism 30 in the locked state. When the first hook 41 and the rotating member 51 rotate, the second hook 42 remains engaged with the locking platform 21a, and the fastening assembly 40 continues to rotate and then switches to the unlocked state.

[0093] Since the fastening assembly can solve the problems of difficult and unsmooth opening of the lid in related technologies, cooking utensils including the fastening assembly can also solve the above problems.

[0094] Applying the technical solution of this embodiment, the fastening component 40 can cooperate with the locking platform 21a and the locking mechanism 30. The fastening component 40 has a dual engaging state and a disengaged state, enabling dual locking and unlocking between the cover component 20 and the pot body 10. When the fastening component 40 has a dual engaging state (e.g.) Figures 2a-2d As shown), the fastening component 40 engages with the locking plate portion 21a, and simultaneously, the locking mechanism 30 is in the locked state, doubly locking the lid assembly 20 and the pot body 10. In this state, the cooking appliance can perform pressure cooking. When the fastening component 40 is in the unlocked state (e.g....), Figures 4a-4d As shown, the fastening component 40 separates from the card plate part 21a, and at the same time, the locking mechanism 30 is in the unlocked state, and the lid component 20 and the pot body 10 are unlocked. At this time, the lid component 20 will switch from the closed state to the open state.

[0095] In this embodiment, the fastening component 40 also has a separate snap-fit ​​state (such as...). Figures 3a-3dAs shown), when the fastening component 40 is in the standby state, the fastening component 40 engages with the latching section 21a, the fastening component 40 releases the rotating member 51, and the locking mechanism 30 switches from the locked state to the unlocked state and remains in the unlocked state.

[0096] like Figure 1 and Figure 5 As shown, the cooking appliance in this embodiment also includes an unlocking operation part 60, which is movably mounted on the pot body 10. The unlocking operation part 60 engages with the fastening component 40. When the lid assembly 20 needs to be opened, the user presses the unlocking operation part 60, which drives the fastening component 40 to switch from a double-locking state to a single-locking state, and then to an unlocked state. In this process, the locking mechanism 30 is unlocked first, and then the fastening component 40 is separated from the locking platform 21a, ultimately opening the lid assembly 20. Preferably, the unlocking operation part 60 is a lid-opening button, mounted on the pot body 10 via a fixing ring 61. The unlocking operation part 60 pushes against the bottom end of the fastening component 40.

[0097] like Figure 1 , Figure 9 and Figure 10 As shown, the pot body 10 includes an inner pot 11 with a flanged rim 111. The linkage 52 includes a sliding plate with a groove 521. The locking mechanism 30 includes a mounting plate 31 and a clamp 32 at the bottom of the mounting plate 31. The clamp 32 can lock or unlock the flanged rim 111. The sliding plate moves in a direction perpendicular to the moving direction of the mounting plate 31. A limiting post 311 is provided on the mounting plate 31 and passes through the groove 521. The angle α between the moving direction of the groove 521 and the moving direction of the mounting plate 31 is greater than or equal to 25° and less than 45°. The sliding plate moves in the front-back direction of the lid assembly 20, and the mounting plate 31 moves in the left-right direction of the lid assembly 20.

[0098] To account for errors that may occur during the manufacturing process, and to ensure that there is still some relative movement between the sliding plate and the limiting post 311 after the locking mechanism 30 is locked in place, in Embodiment 1, as follows: Figure 9 and Figure 10As shown, the slide plate is also provided with an extension groove 522 that communicates with the slide groove 521. The extension groove 522 is located at the end of the slide groove 521 away from the rotating part 51, and the extension direction of the extension groove 522 is parallel to the moving direction of the slide plate. Due to the existence of processing errors, when the locking mechanism 30 is locked in place, the slide plate may not have moved into place. If the extension groove 522 is not provided, the slide plate will continue to pull the limiting post 311, causing the locking mechanism 30 to collide with the pot opening flange 111, resulting in damage to the pot opening flange 111. With the extension groove 522, after the locking mechanism 30 is locked in place, there can still be a certain amount of relative movement between the slide plate and the limiting post 311, thereby avoiding the locking mechanism 30 from colliding with the pot opening flange 111.

[0099] like Figures 9 to 11 As shown, a rotatable friction-reducing component 312 is provided on the limiting post 311. Figure 12 As shown, the top of the rotating component 51 is provided with a receiving groove 511, and the front end of the linkage component 52 is provided with a linkage shaft 524. The linkage shaft 524 is located inside the receiving groove 511, and the fastening assembly 40 drives the bottom end of the rotating component 51. The above structure is easy to manufacture, and the cooperation between the two is smoother when the rotating component 51 pulls the linkage component 52. The rotating component 51 is provided with a shaft, and the cover 21 is provided with a shaft hole for mounting the shaft.

[0100] like Figure 1 , Figure 11 and Figure 17 As shown, the cover assembly 20 includes a liner 21 and a metal fixing plate 22 disposed below the liner 21. The locking mechanism 30 includes a mounting plate 31 and a clamp 32 disposed at the bottom of the mounting plate 31. The mounting plate 31 is movably disposed on the metal fixing plate 22. The metal fixing plate 22 is buoyantly mounted below the liner 21 via a connector 24. A positioning structure is provided between the middle of the metal fixing plate 22 and the middle of the liner 21. The cover assembly 20 also includes a faceplate 25 disposed above the liner 21.

[0101] like Figure 1 , Figure 11 and Figure 17As shown, the cover assembly 20 also includes an inner cover 23 disposed below the metal fixing plate 22. A temperature sensing element 231 is disposed at the center of the inner cover 23 and is connected to the liner 21. The metal fixing plate 22 is provided with a through hole 221 through which the temperature sensing element 231 passes. The positioning structure includes a positioning hole 214 and a positioning post 222 disposed in the positioning hole 214. The positioning hole 214 is disposed on the liner 21, and the positioning post 222 is disposed on the metal fixing plate 22. In the above structure, the radial movement of the metal fixing plate 22 relative to the liner 21 is restricted by the cooperation of the temperature sensing element 231 and the through hole 221, and the rotation of the metal fixing plate 22 and the liner 21 is prevented by the cooperation of the positioning hole 214 and the positioning post 222.

[0102] like Figure 6 As shown, to facilitate the installation of the third reset member 53, the cover assembly 20 includes a cover 21, a first hook 525 is provided on the slide plate, and a second hook 213 is provided on the cover 21. The transmission mechanism 50 also includes a third reset member 53 installed between the first hook 525 and the second hook 213. The third reset member 53 is a tension spring, which applies an elastic force to the slide plate, causing the slide plate to move backward and the locking mechanism 30 to be in the unlocked state.

[0103] like Figure 7 and Figure 8 As shown, the cover assembly 20 includes a cover 21, a locking platform 21a is disposed on the cover 21, the locking platform 21a includes a horizontal plate 211 and a vertical plate 212 connected to the horizontal plate 211, a fastening assembly 40 engages with the top surface of the vertical plate 212, a rotating member 51 is located above the horizontal plate 211 and behind the vertical plate 212, and a third notch 2121 is provided in the middle of the top surface of the vertical plate 212 to avoid the rotating member 51. This structure allows the locking platform 21a to avoid the rotating member 51 to a certain extent through the third notch 2121, making the cooking utensil structure more compact.

[0104] The following will describe the process of closing and opening the lid of the cooking appliance in Example 1.

[0105] The process of closing the lid of the cooking appliance in Example 1 is as follows:

[0106] Phase 1: As Figures 4a to 4e The inclined surface of the lower surface of the clamping section 21a causes the first hook 41 to move, and at the same time drives the second hook 42 to move. At this time, the clamp 32 is in the fully open state, the limiting post 311 is in the initial position, and the first distance between the clamp 32 and the pot opening flange 111 is L3 (design gap).

[0107] Phase Two: As Figures 3a to 3eWhen the lid assembly 20 reaches the set position, the second hook 42 is reset and latched onto the latching plane 21b of the latching section 21a under the action of the second reset member 45, so that the pot body 10 and the lid assembly 20 are latched together, ensuring that the lid assembly will not pop open or shake. At this time, the first hook 41 does not touch the rotating member 51, the slide plate does not move, the caliper 32 is in the fully open state, and the limit post 311 is in the initial position.

[0108] Furthermore, the first hook 41 is fastened to the fastening plane 21b of the clasp portion 21a. The first hook 41 touches the rotating part 51, which simultaneously drives the slide plate to move, forcing the caliper 32 to move and the limiting post 311 to the second position.

[0109] When the limiting post 311 moves from the initial position to the second position, there is still a distance between the caliper 32 and the pot flange 111 to prevent the caliper 32 from contacting the pot flange 111. The second distance between the two is L4, where L4 < L3.

[0110] Phase Three: As Figures 2a to 2d The first hook 41 contacts the bottom end of the rotating part 51, causing it to rotate and forcing the slide plate to slide, so that the caliper 32 locks the pot opening flange 111 and the limiting post 311 is in the third position; the force F of the first reset part 44 is greater than the force f of the third reset part 53.

[0111] The process of opening the lid of the cooking appliance in Example 1 is as follows:

[0112] Phase 1: As Figures 2a to 2d The limiting post 311 is in the third position, and the caliper 32 is located below the flange 111 of the pot opening;

[0113] Phase Two: As Figures 3a to 3e Push the unlocking operation unit 60 to drive the first hook 41 to move. At the same time, the third reset member 53 pulls the slide plate to drive the caliper 32 to move. When the limit post 311 moves to the second position, the second hook 42 contacts the first hook 41. The second hook 42 is still engaged on the engagement plane 21b. At this time, the caliper 32 is completely disengaged from the pot opening flange 111.

[0114] Phase Three: As Figures 4a to 4e The first hook 41 drives the second hook 42 to move, causing the second hook 42 to disengage from the fastening plane 21b, and the cover assembly 20 opens, completing the opening of the cover.

[0115] like Figure 18 and Figure 19 As shown, the cooking appliance in Embodiment 2 differs from that in Embodiment 1 only in the unlocking operation unit's driving method for unlocking.

[0116] Specifically, in Embodiment 2, the unlocking operation part 60 is movably disposed on the pot body 10, and the unlocking operation part 60 is driven to cooperate with the rotating part 51 through the push structure 70. In Embodiment 2, the unlocking operation part 60 does not cooperate with the fastening component 40 but cooperates with the rotating part 51. When it is necessary to open the lid assembly 20, when the user presses the unlocking operation part 60, the unlocking operation part 60 can drive the rotating part 51 to rotate, which can drive the locking mechanism 30 to unlock. At the same time, the rotation of the rotating part 51 can drive the fastening component 40 to switch from a double-locking state to a single-locking state, and then switch to an unlocking state. In the above process, the locking mechanism 30 is unlocked first, and then the fastening component 40 is separated from the locking platform 21a, finally realizing the opening of the lid assembly 20. Preferably, the unlocking operation part 60 is a lid opening button, which is disposed on the pot body 10 through the fixing ring 61. The unlocking operation part 60 pushes the bottom end of the push structure 70.

[0117] The push-up structure 70 includes multiple components. In Embodiment 2, the push-up structure 70 includes a first push-up member 71, a second push-up member 72, and a third push-up member 73. The first push-up member 71 moves horizontally under the push of the unlocking operation unit 60. The second push-up member 72 is disposed on the pot body and can move vertically when the first push-up member 71 moves horizontally. The third push-up member 73 is disposed on the lid assembly 20 and can move upward when the second push-up member 72 moves upward. Finally, the upward movement of the third push-up member 73 drives the rotating member 51 to rotate.

[0118] like Figure 12 and Figure 15 As shown, the fastening assembly 40 is provided with a first clearance portion to avoid the pushing structure 70, and the rotating component 51 is provided with a pushing inclined surface 512 that cooperates with the pushing structure 70 and a second clearance portion 513 to avoid the pushing structure 70. The above structure makes the overall layout of the cooking appliance more reasonable and the structure more compact.

[0119] like Figure 12 and Figure 15 As shown, the first clearance portion is a fourth notch, and the second clearance portion 513 is a recess provided on the front surface of the rotating member 51, with the bottom of the pushing inclined surface 512 extending into the recess. This structure is simple and easy to implement. Extending the bottom of the pushing inclined surface 512 into the recess reduces the size of the rotating member 51 while ensuring the fit between the pushing structure 70 and the pushing inclined surface 512. This results in a more compact overall structure for the cooking appliance.

[0120] The cooking appliance in this application is a pressure cooker, but it can also be a rice cooker, slow cooker, frying machine, food processor, or other appliances with other functions.

[0121] 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. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0122] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0123] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
