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 appliance technology, and more specifically, to a cooking utensil. 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 structure formed by the locking mechanism on the lid and the pot body inside the pot body through the locking teeth on the lid and the locking mechanism on the pot body; the second locking structure is a locking structure formed by the locking mechanism on the lid and the locking mechanism 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 cooking utensil to solve the problem in related technologies where pressing is difficult during the opening process, resulting in the lid not opening smoothly or even being unable to open.

[0008] To achieve the above objectives, this utility model provides a cooking appliance, comprising: a pot body; a lid assembly, which is closably mounted on the pot body, with its rear portion hinged to the pot body and its front portion having a locking mechanism, and the lid assembly having an open state and a closed state; a locking mechanism, movably mounted on the lid assembly and having a locked state for locking the pot body and an unlocked state for unlocking the pot body; a latching mechanism, rotatably mounted on the pot body, having a double-locking state and a unlocked state for engaging with the locking mechanism; and a transmission mechanism, mounted on the lid assembly and located between the latching mechanism and the locking mechanism; when the latching mechanism is in the double-locking state, the latching mechanism engages with the locking mechanism, and the latching mechanism, through the transmission mechanism, keeps the locking mechanism in the locked state; when the transmission mechanism is active, the portion of the latching mechanism connected to the locking mechanism remains relatively stationary, and the latching mechanism continues to rotate and switches to the unlocked state.

[0009] By applying the technical solution of this utility model, the latching mechanism can cooperate with the latching platform and the locking mechanism. The latching mechanism has a double latching state and a double unlocking state, enabling double locking and unlocking between the lid assembly and the pot body. When the latching mechanism is in the double latching state, it latches with the latching platform, and simultaneously, the locking mechanism is in the locked state, doubly locking the lid assembly and the pot body. In this state, the cooking appliance can perform pressure cooking. When the latching mechanism is in the unlocking state, it separates from the latching platform, and simultaneously, the locking mechanism is in the unlocked state, unlocking the lid assembly and the pot body. At this time, the lid assembly switches from the closed state to the open state. In the solution of this utility model, when the latching mechanism drives the transmission mechanism, the part connected to the latching platform can remain relatively stationary, and the latching mechanism continues to rotate, thus switching to the unlocking state. In existing technologies, for solutions where the latching mechanism works in conjunction with both the latching platform and the locking mechanism, the lid assembly moves upward relative to the pot body during the locking mechanism's movement. This makes the unlocking process of the locking mechanism susceptible to interference from other components, resulting in difficult pressing, unsmooth opening, or even complete difficulty in opening the lid. When the latching mechanism drives the transmission mechanism, it remains engaged with the latching platform and thus stationary. At this time, the position of the lid assembly relative to the pot body remains unchanged. In this state, the latching mechanism continues to rotate and switches to the unlocked state. That is, the latching mechanism can release the transmission mechanism simultaneously with or before separating from the latching platform, allowing the locking mechanism to switch from the locked state to the unlocked state. This prevents interference between the locking mechanism's movement and other components within the lid assembly, resulting in smoother movement and improved ease of opening and closing the lid assembly. Therefore, the technical solution of this invention can solve the problem in related technologies where difficult pressing during the lid opening process leads to unsmooth opening or even the inability to open the lid.

[0010] Furthermore, the transmission mechanism includes a rotating component rotatably mounted on the cover assembly and a linkage component disposed between the rotating component and the locking mechanism. When the latching mechanism is in a double-locking state, the latching mechanism abuts against the rotating component and pulls the linkage component to keep the locking mechanism in a locked state. When the latching mechanism is in an unlocked state, the rotating component engages with the stop of the latching platform. This ensures that the rotating component always stops at a preset position, and when the latching mechanism re-engages with the latching platform, the starting position of the rotating component's rotation is the same, and the angle of rotation is consistent each time, thus ensuring that the locking mechanism locks in place every time. This avoids the safety hazard caused by the locking mechanism not locking properly due to changes in the starting position of the rotating component.

[0011] Furthermore, the cover assembly includes a liner, a locking platform is disposed on the liner, and the locking platform includes a horizontal plate and a vertical plate connected to the horizontal plate. A locking mechanism engages with the top surface of the vertical plate. A rotating component is located above the horizontal plate and behind the vertical plate. When the locking mechanism is in the unlocked state, the rotating component engages with the vertical plate as a stop. This structural layout is reasonable, unlikely to cause movement interference, and enables the locking mechanism to engage with the cover assembly.

[0012] Furthermore, a notch is provided in the middle of the vertical plate to allow for the rotation of the component. When the rotation is engaged with the stop of the mounting plate, the rotation is positioned within the notch. This makes the cooking utensil structure more compact.

[0013] Furthermore, the countertop also includes an inclined plate positioned between the horizontal and vertical plates. This inclined plate effectively avoids other moving parts, making the overall structure of the cooking appliance more compact.

[0014] Furthermore, the width L of the top surface of the vertical plate is greater than or equal to 1 mm and less than or equal to 5 mm. The above structure can ensure stable engagement between the locking mechanism and the vertical plate, and can also avoid interference between the locking mechanism and the vertical plate during movement.

[0015] Furthermore, the latching mechanism includes a first latch and a second latch, both of which are rotatably mounted on the pot body. When the latching mechanism is in a double-locking state, the second latch is engaged with the latching platform, and the first latch abuts against the rotating component and pulls the linkage to keep the locking mechanism in a locked state. When the latching mechanism is in an unlocked state, the second latch disengages from the latching platform, the first latch releases the rotating component, and the locking mechanism remains in an unlocked state. This structure better enables the first latch to drive the rotating component to rotate while the second latch remains relatively stationary with respect to the latching platform, allowing the first latch to continue rotating and then switch to the unlocked state.

[0016] Furthermore, the latching mechanism also has a separate latching state. When the latching mechanism is in the separate latching state, the second latch engages with the latching platform, the first latch releases the rotating component, and the locking mechanism switches from the locked state to the unlocked state and remains in the unlocked state. This structure better enables the second latch to remain relatively stationary when it drives the rotating component to rotate, while the first latch continues to rotate and then switches to the unlatched state. This structure facilitates smoother opening and closing of the cover assembly.

[0017] Furthermore, the cover assembly includes a liner and a metal fixing plate disposed below the liner. The locking mechanism includes a mounting plate and a clamp disposed on the mounting plate. The mounting plate is movably disposed on the metal fixing plate, and the metal fixing plate is buoyantly mounted below the liner via a connector. The aforementioned metal fixing plate has good strength and can effectively ensure the movement trajectory of the locking mechanism.

[0018] Furthermore, the pot body includes an inner pot with a flanged rim. The linkage includes a sliding plate with a groove. The locking mechanism includes a mounting plate and a clamp mounted on the mounting plate. The clamp can lock or unlock the flanged rim. The sliding plate moves in a direction perpendicular to the mounting plate. A limiting post is provided on the mounting plate, passing through the groove. This structure ensures effective locking of the mechanism and improves safety during use. Attached Figure Description

[0056] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use.

[0057] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale.

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.

[0059] In Chinese utility model patent application number 202221673921.0, a latch (a drive lever with a hook in this patent) is provided. This structure, in order to allow the same latch to engage with both the caliper structure and the locking platform, simultaneously unlocks the caliper and separates the latch from the platform, or simultaneously locks the caliper and engages the latch with the platform. Therefore, the latch needs to be engaged deeply. In actual use, when the lid assembly switches from an open to a closed state, the latch engagement point changes each time, making it impossible to guarantee a proper engagement. When the lid assembly needs to be opened, the latch rotates, causing the caliper to unlock. During this process, the lid assembly is moved upwards by its rear torsion spring, which may cause the caliper to come into contact with the inner pot, creating friction and potentially preventing the caliper from disengaging. Even if the caliper unlocks successfully, the upward movement of the lid assembly increases the gap between it and the pot body, increasing the friction between the latch and the platform, making it difficult to open the lid.

[0060] 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.

[0061] like Figure 1 As shown, the cooking appliance in this embodiment includes: a pot body 10, a lid assembly 20, a locking mechanism 30, a buckle mechanism 40, and a transmission mechanism 50.

[0062] 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.

[0063] 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.

[0064] The latching mechanism 40 is rotatably mounted on the pot body 10. The latching mechanism 40 has a double latching state and a release state that cooperate with the latching platform 21a.

[0065] The transmission mechanism 50 is disposed on the cover assembly 20 and located between the latching mechanism 40 and the locking mechanism 30. Specifically, when the cover assembly 20 is in the closed state, the latching mechanism 40 switches from a double-locking state to a unlocking state when subjected to force; when the cover assembly 20 switches from the open state to the closed state, the cover assembly 20 drives the latching mechanism 40 to switch from the unlocking state to the double-locking state.

[0066] When the latching mechanism 40 is in a double latching state, the latching mechanism 40 latches with the latching platform 21a. The latching mechanism 40 keeps the locking mechanism 30 in a locked state through the transmission mechanism 50. When the latching mechanism 40 is in an unlocked state, the latching mechanism 40 separates from the latching platform 21a. The latching mechanism 40 releases the transmission mechanism 50 and the locking mechanism 30 remains in an unlocked state. When the latching mechanism 40 drives the transmission mechanism 50 to move, the part of the latching mechanism 40 connected to the latching platform 21a can remain relatively stationary. The latching mechanism 40 continues to rotate and then switches to the unlocked state.

[0067] Applying the technical solution of this embodiment, the latching mechanism 40 can cooperate with the latching platform 21a and the locking mechanism 30. The latching mechanism 40 has a dual latching state and a dual unlocking state, enabling dual locking and unlocking between the cover assembly 20 and the pot body 10. When the latching mechanism 40 has a dual latching state, as shown... Figures 2a-2d As shown, the latching mechanism 40 engages with the latching section 21a, and simultaneously, the locking mechanism 30 is in a locked state, resulting in a double lock between the lid assembly 20 and the pot body 10. In this state, the cooking appliance can perform pressure cooking. When the latching mechanism 40 is in the unlocked state... Figures 4a-4dAs shown, the latching mechanism 40 separates from the latching platform 21a, while the locking mechanism 30 is in the unlocked state, unlocking the lid assembly 20 and the pot body 10. At this time, the lid assembly 20 switches from the closed state to the open state. In this embodiment, when the latching mechanism 40 drives the transmission mechanism 50, the part connected to the latching mechanism 40 and the latching platform 21a can remain relatively stationary. The latching mechanism 40 continues to rotate and then switches to the unlocked state. In the prior art, for schemes where the latching mechanism cooperates with both the latching platform and the locking mechanism, during the movement of the locking mechanism, the lid assembly moves upward relative to the pot body. This makes the unlocking process of the locking mechanism susceptible to interference from other components, resulting in difficult pressing, unsmooth opening of the lid, or even difficulty. When the latching mechanism 40 drives the transmission mechanism 50, the latching mechanism 40 remains engaged with the latching platform 21a and thus remains stationary. At this time, the position of the lid assembly 20 relative to the pot body 10 remains unchanged. In this state, the latching mechanism 40 continues to rotate and switches to the unlocked state. That is, the latching mechanism 40 can release the transmission mechanism 50 simultaneously with or before separating from the latching platform 21a, causing the locking mechanism 30 to switch from the locked state to the unlocked state. In this way, the movement of the locking mechanism 30 will not interfere with other components within the lid assembly 20, resulting in smoother movement and improved ease of opening and closing of the lid assembly 20. Therefore, the technical solution of this embodiment can solve the problem in related technologies where pressing during the opening process is difficult, leading to unsmooth opening or even inability to open the lid.

[0068] like Figure 4d As shown, the transmission mechanism 50 includes a rotating member 51 rotatably mounted on the cover assembly 20 and a linkage member 52 disposed between the rotating member 51 and the locking mechanism 30. When the latching mechanism 40 is in a double-locking state, the latching mechanism 40 abuts against the rotating member 51 and pulls the linkage member 52 to keep the locking mechanism 30 in a locked state; when the latching mechanism 40 is in an unlocked state, the rotating member 51 engages with the stop portion 21a. The aforementioned rotating member is also called a swing rod.

[0069] In this embodiment, when the latching mechanism 40 is in the unlocked state, the rotating member 51 engages with the stop portion 21a, ensuring that the rotating member 51 always stops at a preset position. Therefore, when the latching mechanism 40 re-engages with the stop portion 21a, the starting position of the rotating member 51's rotation is the same, and the angle of rotation is consistent each time, ensuring that the locking mechanism always locks in place. This avoids the safety hazard caused by the locking mechanism failing to lock properly due to changes in the starting position of the rotating member 51.

[0070] In an embodiment not shown in the figure, the transmission mechanism may also exclude rotating components and include only linkage components. In this case, a part of the latching mechanism directly cooperates with the linkage component, so that while the latching mechanism switches states, it directly drives the linkage component to move, thereby driving the locking mechanism to switch between locked and unlocked states.

[0071] like Figure 7 and Figure 8 As shown, the cover assembly 20 includes a liner 21, a locking platform 21a disposed on the liner 21, and the locking platform 21a includes a horizontal plate 211 and a vertical plate 212 connected to the horizontal plate 211. A locking mechanism 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. When the locking mechanism 40 is in the unlocked state, the rotating member 51 engages with the vertical plate 212. The above structural layout is reasonable, unlikely to cause movement interference, and can achieve the locking engagement between the locking mechanism 40 and the cover assembly 20. The top surface of the locking mechanism 40 and the vertical plate 212 is also referred to as the fastening plane 21b.

[0072] like Figure 7 , Figure 8 and Figure 8a As shown, a 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 mounting plate 21a to avoid the rotating member 51 to a certain extent through the notch 2121, ensuring the stroke of the rotating member 51 while reducing the size of the mounting plate 21a. This structure makes the cooking appliance more compact.

[0073] like Figure 8a As shown, the mounting plate 21a also includes an inclined plate 215 disposed between the horizontal plate 211 and the vertical plate 212. The inclined plate 215 effectively avoids other moving parts, such as the latching mechanism 40, and makes the overall structure of the cooking appliance more compact. The inclined plate 215 can be a sloping structure or an arc-shaped structure, as long as it can fulfill the avoidance function.

[0074] like Figure 8a As shown, the width L of the top surface of the vertical plate 212 is greater than or equal to 1 mm and less than or equal to 5 mm. The width L of the top surface of the vertical plate 212 can be 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, or 5 mm. Other values ​​are also possible. This structure ensures stable engagement between the locking mechanism 40 and the vertical plate 212 while preventing interference between the locking mechanism 40 and the vertical plate 212 during movement.

[0075] In this embodiment, as Figure 1 and Figures 14 to 16As shown, the latching mechanism 40 includes a first latch 41 and a second latch 42, both of which are rotatably mounted on the pot body 10. When the latching mechanism 40 is in a double latching state, the second latch 42 latches with the latching platform 21a, and the first latch 41 abuts against the rotating member 51 and pulls the linkage member 52 to keep the locking mechanism 30 in a locked state. When the latching mechanism 40 is in a single latching state, the second latch 42 latches with the latching platform 21a, the first latch 41 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. When the latching mechanism 40 is in a de-latching state, the second latch 42 separates from the latching platform 21a, the first latch 41 releases the rotating member 51, and the locking mechanism 30 remains in the unlocked state. The first latch 41, in conjunction with the rotating member 51 and the linkage member 52, controls the locking and unlocking of the locking mechanism 30. The second latch 42 engages or disengages with the locking platform 21a. The movement of the locking mechanism 30 occurs when the second latch 42 engages with the locking platform 21a. During the movement of the locking mechanism 30, the lid assembly 20 does not move upwards relative to the pot body 10, ensuring that the locking and unlocking processes of the locking mechanism 30 are not interfered with by other components. During the opening process, after the locking mechanism 30 has finished moving, the first latch 41 drives the second latch 42 to rotate, causing the second latch 42 to disengage from the locking platform 21a. During the closing process, after the second latch 42 engages with the locking platform 21a, the first latch 41 rotates, and the rotating member 51 and the linkage member 52 work together to move the locking mechanism 30 to achieve locking.

[0076] The latching mechanism includes a first latch 41 and a second latch 42. The first latch 41 is rotatably disposed and has an independent rotation state and a linked rotation state. The second latch 42 is rotatably disposed and adjacent to the first latch 41. When the first latch 41 is in the independent rotation state, the second latch 42 is stationary and the first latch 41 rotates relative to the second latch 42. When the first latch 41 is in the linked rotation state, the first latch 41 drives the second latch 42 to rotate together.

[0077] like Figures 14 to 16As shown, the first buckle 41 includes a first rotating plate 411 and a first hook 412 disposed at the end of the first rotating plate 411. The second buckle 42 includes a second rotating plate 421 and a second hook 422 disposed at the end of the second rotating plate 421. The first rotating plate 411 and the second rotating plate 421 are stacked. A clearance space 46 is provided between the first hook 412 and the second hook 422 so that when the first buckle 41 rotates relative to the second buckle 42, the second hook 422 avoids the first hook 412. The above structure can realize the independent rotation of the first buckle 41 relative to the second buckle 42 and the synchronous movement between the two. The structure is simple, easy to implement, and the movement state is easy to control. Due to the clearance space 46, the second buckle 42 can remain stationary, and the first buckle 41 can rotate independently relative to the second buckle 42. The first buckle 41 is formed by... Figure 2d The state is rotated to Figure 3d The state. When the first hook 412 of the first buckle 41 rotates to engage with the second hook 422 of the second buckle 42, the first hook 412 drives the second hook 422 to rotate outward together, and the first buckle 41 and the second buckle 42 are in a state of... Figure 3d The state is rotated to Figure 4d The state.

[0078] In this embodiment, the second latch 42 is located near the first latch 41, and the second latch 42 is closer to the longitudinal axis of the pot body than the first latch 41.

[0079] In this embodiment, the first rotating plate 411 and the second rotating plate 421 are stacked. When the first hook 412 of the first buckle 41 rotates to engage with the second hook 422 of the second buckle 42, the first hook 412 drives the second hook 422 to rotate outward together, and the first buckle 41 and the second buckle 42 are... Figure 3d The state is rotated to Figure 4d The state.

[0080] Specifically, the first hook body 412 is provided with a first abutting surface 414, and the second hook body 422 is provided with a second abutting surface 424. When the first latch 41 is in a linked rotation state, the first abutting surface 414 abuts against the second abutting surface 424, so that the first latch 41 drives the second latch 42 to rotate together. The above structure is simple and the movement process is easy to control.

[0081] like Figure 14 As shown, the first abutment surface 414 is a first inclined surface, and the second abutment surface 424 is a second inclined surface. This structure results in a larger contact area between the first latch 41 and the second latch 42 when they rotate together, thus improving movement stability.

[0082] When the first latch 41 is in the linked rotation state, the lowest point of the first hook 412 is flush 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 the latching platform 21a and be properly engaged. This avoids interference during the reset process, preventing them from engaging properly.

[0083] like Figures 14 to 16 As shown, 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 latch 41 relative to the second latch 42, thereby ensuring the locking stability of the locking mechanism 30 driven by the first latch 41. Preferably, L1 = 1.5L2, or L1 = 2L, or L1 = 2.5L2.

[0084] The end of the first hook 412 has a rounded corner structure. The rounded corner structure facilitates the control of the engagement position between the first buckle 41 and the locking platform 21a. At the same time, when the first buckle 41 is in an independent rotating state, it is less likely to interfere with other structures.

[0085] like Figure 15 and Figure 16 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 shaft portion 4113 is provided on the flange 4112. The second rotating plate 421 is located within the receiving space formed by the plate body 4111 and the flanges 4112 and is provided with a second shaft portion 4213. A first clearance notch 4114 corresponding to the second shaft portion 4213 is also provided on the flange 4112. This structure allows the second buckle 42 to be housed inside the first buckle 41, making the overall structure of the fastening assembly more compact. The first shaft portion 4113 and the second shaft portion 4213 can be either a pin or a shaft hole.

[0086] like Figure 15 As shown, the first rotating plate 411 is provided with a clearance part 43, which can avoid other components.

[0087] like Figure 15 and Figure 16 As shown, a first reset member connecting part 4115 is provided on the first rotating plate 411, and a second reset member connecting part 4215 is provided on the second rotating plate 421. The above structure facilitates the connection of the reset member.

[0088] like Figure 15 and Figure 16As shown, a first reset component positioning part 4116 is also provided on the first rotating plate, and a second reset component positioning part 4216 is provided on the second rotating plate. The above structure is used to position the reset component, ensuring its normal operation. In this embodiment, the first reset component positioning part 4116 is a first positioning rib, and the second reset component positioning part 4216 is a second positioning rib.

[0089] like Figure 16 As shown, a second clearance notch 4221 is provided in the middle of the end of the second hook body 422, extending through in the vertical direction. The second clearance notch 4221 is also used to avoid the rotating part 51, making the overall structure more compact.

[0090] like Figure 15 and Figure 16 As shown, the first rotating plate 411 has a first limiting surface 413 located below the first hook 412, and the second rotating plate 421 has a second limiting surface 423 located below the second hook 422. The first limiting surface 413 and the second limiting surface 423 are flush. When the first latch 41 and the second latch 42 are in a stationary state, the first limiting surface 413 of the first latch 41 abuts against the vertical plate 212, and the second limiting surface 423 of the second latch 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 latch 41 and the second latch 42, so that both are engaged with the fastening plane 21b.

[0091] In this embodiment, the latching mechanism 40 also has a separate latching state, such as... Figures 3a-3d As shown, when the latching mechanism 40 is in the standby state, the second latch 42 of the latching mechanism 40 latches with the latching platform 21a, the first latch 41 of the latching mechanism 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.

[0092] When the latching mechanism 40 is in the standby state, the latching mechanism 40 is latched with the latching platform 21a. At the same time, the locking mechanism 30 is in the unlocked state, and the cover assembly 20 and the pot body 10 are locked separately. This state is a transitional state, and the cover assembly 20 is in this state for a very short time. This state facilitates the smoothness of opening or closing the cover assembly 20.

[0093] like Figure 1As shown, the cooking appliance also includes a first reset member 44 disposed between the pot body 10 and the first latch 41, and a second reset member 45 disposed between the pot body 10 and the second latch 42. The first reset member 44 enables the first latch 41 to remain in a vertical position, and the second reset member 45 enables the second latch 42 to remain in a vertical position. When the lid assembly 20 is in the closed position, the first latch 41 abuts against the rotating member 51 under the elastic force of the first reset member 44, and the second latch 42 is engaged with the locking platform 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 latch 41 can abut against the vertical plate 212 of the locking platform 21a or the vertical plate on the pot body 10 located below the vertical plate 212, thus keeping the first latch 41 in a vertical position. Similarly, the second limiting surface 423 of the second latch 42 can abut against the vertical plate 212 of the latching section 21a or the vertical plate on the pot body 10 located below the vertical plate 212, thereby keeping the second latch 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.

[0094] 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 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 sliding plate moves along the front-back direction of the cover assembly 20, and the mounting plate 31 moves along the left-right direction of the cover assembly 20. The above structure can ensure the effective locking of the locking mechanism 30 and improve the safety of use.

[0095] 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 this embodiment, such as... 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 movement 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 rim flange 111, resulting in damage to the pot rim flange 111. With the extension groove 522, there is still a certain amount of relative movement between the slide plate and the limiting post 311 after the locking mechanism 30 is locked in place, thereby avoiding the collision between the locking mechanism 30 and the pot rim flange 111. The angle α between the slide groove 521 and the movement direction of the mounting plate 31 is greater than or equal to 25° and less than 45°. The smaller the angle α, the smaller the distance the slide plate moves when the mounting plate 31 moves the same distance. This makes the structure of the cooking appliance more compact.

[0096] like Figures 3a to 4e As shown, when the latching mechanism 40 is in the unlocking state, as Figures 4a to 4e The caliper 32 and the flange 111 of the pot opening have a first distance L3, such as Figure 4e When the latching mechanism 40 is in a standby latching state, Figures 3a to 3e There is a second distance L4 between the caliper 32 and the flange 111 of the pot opening. Figure 3e The second distance L4 is less than the first distance L3. The above structure ensures that there is always a distance between the clamp 32 and the pot opening flange 111 before the latching mechanism 40 engages with the latching platform 21a, so as to avoid the lid assembly 20 moving upward relative to the pot body 10, causing the clamp 32 to interfere with the pot opening flange 111 and thus preventing the lid from closing.

[0097] like 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 latching mechanism 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.

[0098] like Figure 1 , Figure 11 and Figure 17 As shown, the cover assembly 20 includes a cover 21 and a metal fixing plate 22 disposed below the cover 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, and the metal fixing plate 22 is buoyantly mounted below the cover 21 via a connector 24. A positioning structure is provided between the middle of the metal fixing plate 22 and the middle of the cover 21.

[0099] The metal fixing plate 22 is buoyantly mounted below the liner 21 via the connector 24, creating a vertical gap between the clamp 32 and the pot rim flange 111. When the inner pot 11 is hot, there is a large amount of steam inside. When the lid is closed, the lid assembly 20 moves upward, causing the clamp 32 to move upward as well. The vertical gap between the clamp 32 and the pot rim flange 111 prevents the clamp 32 from pressing against the inner pot 11 and preventing the lid from closing.

[0100] A bracket is provided on the aforementioned metal fixing plate 22, and the mounting plate 31 is movably mounted on the bracket. The aforementioned cover 21 is prone to deformation when heated, and the center of the cover 21 is prone to arching, especially the edges are prone to warping. The positioning structure enables the center of the metal fixing plate 22 to be positioned relative to the center of the cover 21, preventing the metal fixing plate 22 from shifting due to deformation of the edges of the cover 21, thereby ensuring that the locking mechanism 30 provided on the metal fixing plate 22 can move according to a preset trajectory.

[0101] The metal fixing plate 22 has a first guide groove extending in the left-right direction of the cover 21 on its support, and the cover 21 also has a second guide groove extending in the left-right direction of the cover 21. The limiting post 311 is sequentially inserted into the first guide groove, the second guide groove and the sliding groove 521 from bottom to top. In this embodiment, a face cover 25 is also provided above the cover 21.

[0102] like Figure 1 , Figure 11 and Figure 17 As 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 has 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 within 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 cooperation between the temperature sensing element 231 and the through hole 221 restricts the radial movement of the metal fixing plate 22 relative to the liner 21. Furthermore, the cooperation between the positioning hole 214 and the positioning post 222 prevents the metal fixing plate 22 from rotating relative to the liner 21.

[0103] Of course, as a feasible implementation, the positioning post can be omitted, and the corresponding function of the positioning post can be achieved using the temperature sensing element 231, that is, the positioning function can be achieved solely through the temperature sensing element 231. When the temperature sensing element 231 is located at the center of the inner cover 23, the temperature sensing element 231 and the through hole 221 need to be in anti-rotation engagement. When the temperature sensing element 231 is off-center from the center of the inner cover 23, the temperature sensing element 231 does not need to be in anti-rotation engagement with the through hole 221.

[0104] 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.

[0105] In this embodiment, to simplify the structure and save costs, the cover assembly 20 includes a liner 21 and an inner cover 23 disposed below the liner 21. The inner cover 23 is provided with a stop rod that can float up and down, and the linkage 52 is provided with a limiting hole that cooperates with the stop rod.

[0106] like Figure 1 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 latching mechanism 40. When the lid assembly 20 needs to be opened, the user presses the unlocking operation part 60, which drives the latching mechanism 40 to switch from a double-locking state to a single-locking state, and then to an unlocking state. In this process, the locking mechanism 30 is unlocked first, and then the latching mechanism 40 is separated from the latching 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 latching mechanism 40.

[0107] The following will describe the process of closing and opening the lid of the cooking appliance in this embodiment.

[0108] The process of closing the lid of the cooking appliance in this embodiment is as follows:

[0109] Phase 1: As Figures 4a to 4e The inclined surface of the lower surface of the clamping section 21a causes the first latch 41 to move, and at the same time drives the second latch 42 to move. At this time, the clamp 32 is in a 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 the L3 design gap.

[0110] Phase Two: As Figures 3a to 3e When the lid assembly 20 reaches the set position, the second latch 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 fastened together, ensuring that the lid assembly will not pop open or shake. At this time, the first latch 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.

[0111] Furthermore, the first buckle 41 is fastened to the fastening plane 21b of the clamping platform 21a. The first buckle 41 triggers the rotating member 51, which in turn drives the slide plate to move, forcing the caliper 32 to move and the limiting post 311 to the second position.

[0112] 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.

[0113] Phase Three: As Figures 2a to 2d The first buckle 41 contacts the bottom end of the rotating part 51, causing it to rotate and forcing the slide plate to slide, so that the clamp 32 clamps 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.

[0114] The process of opening the lid of the cooking appliance in this embodiment is as follows:

[0115] 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;

[0116] Phase Two: As Figures 3a to 3e Push the unlocking operation unit 60 to drive the first buckle 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 buckle 42 contacts the first buckle 41. The second buckle 42 is still fastened on the fastening plane 21b. At this time, the caliper 32 is completely disengaged from the pot opening flange 111.

[0117] Phase Three: As Figures 4a to 4e The first buckle 41 drives the second buckle 42 to move, causing the second buckle 42 to disengage from the fastening plane 21b, and the cover assembly 20 opens, completing the opening of the cover.

[0118] 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.

[0119] 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.

[0120] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0121] 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.

[0122] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
