Description

[0001] Related Applications

[0002] This invention claims the priority of invention patent application filed on December 29, 2023, with application number 202311873884.7 and invention name “Cooking Utensils”, and all the contents thereof are incorporated by reference into this application. Technical Field

[0003] The present invention relates to the field of small household appliances, and in particular to a cooking utensil. Background Art

[0004] In the related art, the cooking utensil includes a pot body and a cover body. In order to ensure that the cover body can be stably connected to the pot body, a double locking structure is provided between the cover body and the pot body. The first locking structure is a locking structure formed by the locking cover on the cover body and the pot body in the pot body through the cover teeth and the pot teeth; the second locking structure is a locking structure formed by the clamping platform on the cover body and the buckle on the pot body.

[0005] The first locking structure needs to be unlocked by rotating the handle on the cover, and the second locking structure needs to be unlocked by pressing a button on the pot body. Therefore, when the user needs to open the cover, he needs to rotate the handle first and then press the button to unlock, which is complicated and makes the user experience poor.

[0006] In the related art, the Chinese utility model patent with application number 202221673921.0 provides a cooking utensil that can solve the problem of complicated operation when the user opens the lid. In the above patent, a lid opening button, a driving lever, a transmission lever, a transmission plate and a caliper structure are provided. By pressing the lid opening button, the lid opening button applies force to the driving lever, the hook of the driving lever is separated from the card platform of the cover body, and the hook of the driving lever no longer limits the transmission lever, so that the transmission rod moves forward, and the caliper structure switches to the unlocked state, realizing double unlocking by pressing the lid opening button, which simplifies the user's operation.

[0007] However, in actual use, the solution of the above patent may cause the lid to be opened unsmoothly or even unable to be opened due to the difficulty in pressing during the opening process. Summary of the invention

[0008] The main purpose of the present invention is to provide a cooking utensil to solve the problem in the related art that the lid is opened unsmoothly or even cannot be opened due to the difficulty in pressing during the lid opening process.

[0009] To achieve the above object, the present invention provides a cooking appliance, comprising: a pot body; a lid assembly which is disposed on the pot body in an openable and closable manner, the rear part of the lid assembly is hinged to the pot body, a clamping table portion is arranged at the front part of the lid assembly, and the lid assembly has an open state and a lid-closed state; a locking mechanism which is movably arranged on the lid assembly and has a locking state for locking the pot body and an unlocking state for unlocking the pot body; a snap mechanism which is rotatably arranged on the pot body, and the snap mechanism has a double clamping state for cooperating with the clamping table portion and an unlocking state; a transmission mechanism which includes a rotating member rotatably arranged on the lid assembly and a linkage member arranged between the rotating member and the locking mechanism, and the snap mechanism can drive the rotating member to rotate; when the snap mechanism is in the double clamping state, the snap mechanism is clamped with the clamping table portion, the snap mechanism abuts against the rotating member and pulls the linkage member to keep the locking mechanism in the locking state, when the snap mechanism drives the rotating member to rotate, the portion of the snap mechanism connected to the clamping table portion can remain relatively stationary, and the snap mechanism continues to rotate and then switches to the unlocking state.

[0010] Applying the technical solution of the present invention, the snap mechanism can cooperate with the clamping table portion and the locking mechanism. The snap mechanism has a double clamping state and an unlocking state, and can realize double locking and unlocking between the lid assembly and the pot body. When the snap mechanism has the double clamping state, the snap mechanism is clamped with the clamping table portion. At the same time, the locking mechanism is in the locking state, and the lid assembly and the pot body are double-locked. In this state, the cooking appliance can perform pressure cooking. When the snap mechanism is in the unlocking state, the snap mechanism is separated from the clamping table portion. At the same time, the locking mechanism is in the unlocking state, and the lid assembly and the pot body are unlocked. At this time, the lid assembly will switch from the lid-closed state to the open state. In the solution of the present invention, when the snap mechanism drives the rotating member to rotate, the portion of the snap mechanism connected to the clamping table portion can remain relatively stationary, and the snap mechanism continues to rotate and then switches to the unlocking state. In the prior art, for the solution in which the snap mechanism cooperates with the clamping table portion and the locking mechanism at the same time, during the movement of the locking mechanism, the lid assembly will move upward relative to the pot body, which makes the unlocking process of the locking mechanism vulnerable to interference from other components, resulting in laborious pressing, unsmooth opening of the lid or even difficulty. When the snap mechanism drives the rotating member to rotate, the snap mechanism remains clamped with the clamping table portion and thus remains stationary. At this time, the position of the lid assembly relative to the pot body remains unchanged. In this state, the snap mechanism continues to rotate and then switches to the unlocking state, that is, the snap mechanism can release the rotating member while or before separating from the clamping table portion, so that the locking mechanism switches from the locking state to the unlocking state. In this way, the movement of the locking mechanism will not interfere with other components in the lid assembly, and the movement is smoother, thereby improving the smoothness of opening or closing the lid assembly. Therefore, the technical solution of the present invention can solve the problems in the related art that the lid opening process is laborious, resulting in unsmooth lid opening or even inability to open the lid.

[0011] Furthermore, the cooking appliance further comprises an unlocking operation part, which is movably arranged on the pot body and is driven and matched with the buckle mechanism. When the cover assembly needs to be opened, the user presses the unlocking operation part, and the unlocking operation part can drive the buckle mechanism to switch from the double-engaged state to the unlocked state.

[0012] Furthermore, the cooking appliance further comprises an unlocking operation part, which is movably arranged on the cover assembly, and the unlocking operation part cooperates with the rotating member. When the cover assembly needs to be opened, the user presses the unlocking operation part, and the unlocking operation part can drive the rotating member to rotate, thereby driving the buckle mechanism to switch from the double-engaged state to the unlocked state.

[0013] Furthermore, the buckle mechanism includes a first buckle and a second buckle, and the first buckle and the second buckle are both rotatably arranged on the pot body, wherein when the buckle mechanism is in a double-clamping state, the second buckle is clamped with the clamping platform, the first buckle abuts against the rotating member and pulls the linkage member to keep the locking mechanism in a locked state, and when the buckle mechanism is in an unlocked state, the second buckle is separated from the clamping platform, the first buckle releases the rotating member and the locking mechanism remains in an unlocked state. The above structure can better realize that when the first buckle drives the rotating member to rotate, the second buckle connected to the clamping platform can remain relatively still, and the first buckle continues to rotate and then switches to the unlocked state.

[0014] Furthermore, the first buckle includes a first rotating plate and a first hook body arranged at the end of the first rotating plate, and the second buckle includes a second rotating plate and a second hook body arranged at the end of the second rotating plate, and there is an escape space between the first hook body and the second hook body, so that when the first buckle rotates relative to the second buckle, the second hook body escapes the first hook body. The above structure can realize the independent rotation of the first buckle relative to the second buckle and the synchronous movement between the two, and the structure is simple, easy to realize, and the movement state is easy to control.

[0015] Furthermore, the first hook has a first protruding dimension L1 protruding from the first rotating plate, and the second hook has a second protruding dimension L2 protruding from the second rotating plate, wherein the first protruding dimension L1 and the second protruding dimension L2 satisfy L1≥1.5L2. The above structure can ensure the rotation amount of the first buckle relative to the second buckle, thereby ensuring the locking stability of the locking mechanism driven by the first buckle.

[0016] Furthermore, the cooking utensil further comprises a first resetting member arranged between the pot body and the first buckle and a second resetting member arranged between the pot body and the second buckle. The first resetting member can keep the first buckle in a vertical state, and the second resetting member can keep the second buckle in a vertical state.

[0017] Further, the cooking pot body includes an inner pot which has a flanged rim. The linkage member includes a sliding plate on which a sliding groove is provided. The locking mechanism includes a mounting plate and a caliper provided on the mounting plate. The caliper can lock or unlock the flanged rim. The moving direction of the sliding plate is perpendicular to the moving direction of the mounting plate. A limiting post penetrating through the sliding groove is provided on the mounting plate. The included angle α between the sliding groove and the moving direction of the mounting plate is greater than or equal to 25° and less than 45°. The above structure makes the structure of the cooking appliance more compact.

[0018] Further, an extension groove communicating with the sliding groove is also provided on the sliding plate. The extension groove is provided at one end of the sliding groove away from the rotating member, and the extending direction of the extension groove is parallel to the moving direction of the sliding plate. The above structure enables a certain relative movement to exist between the sliding plate and the limiting post after the locking mechanism is locked in place, thereby avoiding mutual collision between the locking mechanism and the flanged rim.

[0019] Further, the buckle mechanism also has a single clamping state. When the buckle mechanism is in the single clamping state, the buckle mechanism is clamped with the clamping table portion, the buckle mechanism releases the rotating member and the locking mechanism switches from the locked state to the unlocked state and remains in the unlocked state. The above structure facilitates improving the smoothness of opening or closing of the cover assembly.

[0020] Further, when the buckle mechanism is in the unclamped state, there is a first distance between the caliper and the flanged rim. When the buckle mechanism is in the single clamping state, there is a second distance between the caliper and the flanged rim, and the second distance is less than the first distance. The above structure ensures that there is always a distance between the caliper and the flanged rim before the buckle mechanism is clamped with the clamping table portion, avoiding interference between the caliper and the flanged rim caused by the upward movement of the cover assembly relative to the cooking pot body and resulting in the inability to close the cover.

[0021] Further, a surrounding plate surrounding the outer periphery of the sliding groove is also provided on the sliding plate. A friction-reducing member that can rotate is provided on the limiting post. The friction-reducing member is located inside the surrounding plate and cooperates with the inner wall of the surrounding plate. The above structure can reduce the friction of the limiting post moving in the sliding groove.

[0022] Further, the friction-reducing member is a ball bearing. The above structure is simple and has a low cost.

[0023] Further, the locking mechanism has a floating position and a descending position. When the locking mechanism is in the floating position and the descending position, the friction-reducing member cooperates with the surrounding plate. In this way, regardless of whether there is an upward pressure in the inner pot, the locking mechanism being in the floating position or the descending position can ensure reducing the friction during the sliding process of the limiting post.

[0024] Further, a receiving groove is provided at the top end of the rotating member, and a linkage shaft is provided at the front end of the linkage member. The linkage shaft is located inside the receiving groove, and the buckle mechanism drives the lower end of the rotating member. The above structure is easy to process, and the cooperation between the rotating member and the linkage member is smoother when the rotating member pulls the linkage member.

[0025] Furthermore, the cover assembly includes a lining cover and a metal fixing plate disposed below the lining cover. The locking mechanism includes a mounting plate and a caliper disposed on the mounting plate. The mounting plate is movably disposed on the metal fixing plate. The metal fixing plate is floatingly mounted below the lining cover through a connecting member. A positioning structure is provided between the middle of the metal fixing plate and the middle of the lining cover. The above positioning structure enables positioning between the middle of the metal fixing plate and the middle of the lining cover, avoiding displacement of the metal fixing plate caused by deformation around the lining cover.

[0026] Furthermore, the positioning structure includes a positioning hole and a positioning post disposed in the positioning hole. One of the positioning hole and the positioning post is disposed on the lining cover, and the other is disposed on the metal fixing plate. Among them, the positioning post is located at the center of the lining cover or the center of the metal fixing plate. The positioning post and the positioning hole are in anti-rotation fit, or the positioning post deviates from the center of the lining cover or the center of the metal fixing plate. The above structure is simple and easy to implement.

[0027] Furthermore, the cover assembly includes a lining cover. A first hook is provided on the sliding plate, a second hook is provided on the lining cover, and the transmission mechanism further includes a third reset member installed between the first hook and the second hook. The above structure facilitates the assembly of the third reset member.

[0028] Furthermore, the cover assembly includes a lining cover and an inner cover disposed below the lining cover. A stop lever that can float up and down is provided on the inner cover, and a limit hole that cooperates with the stop lever is provided on the linkage member. The above structure is simplified and cost is saved.

[0029] Furthermore, a position detection member is provided on the linkage member; or a position detection member is provided on the buckle mechanism. The above structure is for subsequent control of the cooking program.

[0030] Furthermore, the cover assembly includes a lining cover. A clamping table portion is provided on the lining cover. The clamping table portion includes a horizontal plate and a vertical plate connected to the horizontal plate. The buckle mechanism is in clamping fit with the top surface of the vertical plate. The rotating member is located above the horizontal plate and behind the vertical plate. A first notch for avoiding the rotating member is provided in the middle of the top surface of the vertical plate. The above makes the structure of the cooking appliance more compact.

[0075] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way limits the present invention and its application or use. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0076] It should be noted that the terms used here are only for describing the specific implementation manners and are not intended to limit the exemplary implementation manners according to the present application. As used here, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or their combinations.

[0077] Unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that for the convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the said technologies, methods, and devices should be regarded as part of the specification. In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar reference numerals and letters denote similar items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0078] In the Chinese utility model patent with the application number 202221673921.0, a buckle (the driving lever with a hook body in this patent) is provided. In order to make the same buckle cooperate with both the caliper structure and the clamping table, the above-mentioned buckle will simultaneously unlock the caliper and separate the buckle from the clamping table, or simultaneously lock the caliper and engage the buckle with the clamping table. Therefore, it is necessary for the above-mentioned buckle to be buckled deeper. In actual use, when the cover body assembly is switched from the open state to the closed state, the buckling point of the buckle will change each time, and it cannot be ensured that the buckling is in place. When the cover body assembly needs to be opened, during the process of the buckle rotating to unlock the caliper, the upper cover assembly will be driven by the torsion spring at its rear to move upward, which may cause the caliper to contact the inner pot and generate friction, resulting in the problem that the caliper cannot be released. Even if the caliper is successfully unlocked, when the upper cover assembly moves upward, the gap between it and the pot body will become larger, increasing the friction between the buckle and the clamping table and making it difficult to open the cover.

[0079] The technical solution of the present application can solve the above problems. Next, the solution of the present application will be introduced in detail with reference to the drawings.

[0080] As Figure 1 shown, the cooking appliance of Embodiment 1 includes: a pot body 10, a cover body assembly 20, a locking mechanism 30, a buckle mechanism 40, and a transmission mechanism 50.

[0081] The cover body assembly 20 is disposed on the pot body 10 in an openable and closable manner. The rear part of the cover body assembly 20 is hingedly connected to the pot body 10. A clamping table portion 21a is provided at the front part of the cover body assembly 20. The cover body assembly 20 has an open state and a closed state.

[0082] The locking mechanism 30 is movably disposed on the cover body assembly 20 and has a locking state for locking the pot body 10 and an unlocking state for unlocking the pot body 10.

[0083] The buckle mechanism 40 is rotatably arranged on the cooking pot body 10, and the buckle mechanism 40 has a double-latching state and an unlocking state that cooperate with the latching table portion 21a.

[0084] The transmission mechanism 50 includes a rotating member 51 (also known as a swing rod) rotatably arranged on the cover body assembly 20 and a linkage member 52 arranged between the rotating member 51 and the locking mechanism 30. The buckle mechanism 40 can drive the rotating member 51 to rotate.

[0085] Among them, when the cover body assembly 20 is in the closed state, when the buckle mechanism 40 is stressed, the buckle mechanism 40 switches from the double-latching state to the unlocking state; when the cover body assembly 20 switches from the open state to the closed state, the cover body assembly 20 drives the buckle mechanism 40 to switch from the unlocking state to the double-latching state;

[0086] When the buckle mechanism 40 is in the double-latching state, the buckle mechanism 40 is latched with the latching table portion 21a. The buckle mechanism 40 abuts against the rotating member 51 and pulls the linkage member 52 to keep the locking mechanism 30 in the locked state. When the buckle mechanism 40 is in the unlocking state, the buckle mechanism 40 is separated from the latching table portion 21a. The buckle mechanism 40 releases the rotating member 51 and the locking mechanism 30 remains in the unlocked state. When the buckle mechanism 40 drives the rotating member 51 to rotate, the part of the buckle mechanism 40 connected to the latching table portion 21a can remain relatively stationary, and the buckle mechanism 40 continues to rotate and then switches to the unlocking state.

[0087] Applying the technical solution of this embodiment, the buckle mechanism 40 can cooperate with the latching table portion 21a and the locking mechanism 30. The buckle mechanism 40 has a double-latching state and an unlocking state, and can realize double locking and unlocking between the cover body assembly 20 and the cooking pot body 10. When the buckle mechanism 40 has a double-latching state (as Figures 2a - 2d shown), the buckle mechanism 40 is latched with the latching table portion 21a. At the same time, the locking mechanism 30 is in the locked state, and the cover body assembly 20 and the cooking pot body 10 are double-locked. In this state, the cooking appliance can perform pressure cooking. When the buckle mechanism 40 is in the unlocking state (as Figures 4a - 4dAs shown in the figure, the buckle mechanism 40 is separated from the card platform portion 21a, and at the same time, the locking mechanism 30 is in the unlocked state, and the cover assembly 20 and the pot body 10 are unlocked. At this time, the cover assembly 20 will switch from the closed state to the open state. In the scheme of this embodiment, when the buckle mechanism 40 drives the rotating member 51 to rotate, the part of the buckle mechanism 40 connected to the card platform portion 21a can remain relatively still, and the buckle mechanism 40 continues to rotate and then switches to the unlocked state. In the prior art, for the scheme in which the buckle mechanism cooperates with the card platform portion and the locking mechanism at the same time, during the movement of the locking mechanism, the cover assembly will move upward relative to the pot body, which makes the unlocking process of the locking mechanism susceptible to interference from other components, resulting in laborious pressing, and unsmooth or even difficult opening of the cover. When the buckle mechanism 40 drives the rotating member 51 to rotate, the buckle mechanism 40 remains engaged with the card platform portion 21a and remains stationary. At this time, the position of the cover assembly 20 relative to the pot body 10 remains unchanged. In this state, the buckle mechanism 40 continues to rotate and switches to the unlocked state, that is, the buckle mechanism 40 can release the rotating member 51 at the same time or before separating from the card platform portion 21a so that the locking mechanism 30 switches from the locked state to the unlocked state. In this way, the movement of the locking mechanism 30 will not interfere with other components in the cover assembly 20, and the movement is smoother, thereby improving the smoothness of opening or closing the cover assembly 20. Therefore, the technical solution of this embodiment can solve the problem in the related art that the pressure during the opening of the cover is laborious, resulting in the unsmooth opening of the cover, or even the inability to open the cover.

[0088] In the solution of this embodiment, the buckle mechanism 40 also has a single buckle state (such as Figures 3a - 3d As shown), when the buckle mechanism 40 is in a single-clamping state, the buckle mechanism 40 is clamped with the clamping platform portion 21a, the buckle 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.

[0089] When the snap mechanism 40 is in a single snap-in state, the snap mechanism 40 is snap-in with the snap-in portion 21a. At the same time, the locking mechanism 30 is in an unlocked state, and the cover assembly 20 and the pot body 10 are individually locked. This state is a transitional state, and the cover assembly 20 is in this state for a very short time. This state facilitates improving the smoothness of opening or closing the cover assembly 20.

[0090] It should be noted that in other embodiments, there may be no separate latching state. When the second latch is stationary, the locking mechanism may not be completely unlocked when the first latch moves. When the first latch is in a linked rotation state, the first latch continues to drive the second latch to move. At the same time or before the second latch is separated from the card platform, the locking mechanism continues to complete the remaining unlocking stroke.

[0091] like Figure 1As shown, the cooking appliance of the first embodiment further includes an unlocking operation part 60. The unlocking operation part 60 is movably arranged on the pot body 10, and the unlocking operation part 60 is in driving cooperation with the buckle mechanism 40. When the cover assembly 20 needs to be opened, when the user presses the unlocking operation part 60, the unlocking operation part 60 can drive the buckle mechanism 40 to switch from the double-locking state to the single-locking state and then to the unlocking state. In the above process, first, the locking mechanism 30 is unlocked, and then the buckle mechanism 40 is separated from the clamping table part 21a, and finally the cover assembly 20 is opened. Preferably, the unlocking operation part 60 is an opening cover button and is arranged on the pot body 10 through a fixing ring 61. The unlocking operation part 60 pushes against the bottom end of the buckle mechanism 40.

[0092] In the first embodiment, as Figure 1 and Figures 14 - 16 shown, the buckle mechanism 40 includes a first buckle 41 and a second buckle 42. The first buckle 41 and the second buckle 42 are both rotatably arranged on the pot body 10. Among them, when the buckle mechanism 40 is in the double-locking state, the second buckle 42 is clamped with the clamping table part 21a, and the first buckle 41 abuts against the rotating part 51 and pulls the linkage part 52 to keep the locking mechanism 30 in the locking state. When the buckle mechanism 40 is in the single-locking state, the second buckle 42 is clamped with the clamping table part 21a, the first buckle 41 releases the rotating part 51, and the locking mechanism 30 switches from the locking state to the unlocking state and remains in the unlocking state. When the buckle mechanism 40 is in the unlocking state, the second buckle 42 is separated from the clamping table part 21a, the first buckle 41 releases the rotating part 51, and the locking mechanism 30 remains in the unlocking state. The above first buckle 41 cooperates with the rotating part 51 and the linkage part 52 to control the locking and unlocking of the locking mechanism 30, and the second buckle 42 cooperates with the clamping table part 21a to be clamped with or separated from the clamping table part 21a. Moreover, the movement of the locking mechanism 30 is carried out when the second buckle 42 is clamped with the clamping table part 21a. In this way, during the movement of the locking mechanism 30, the cover assembly 20 will not move upward relative to the pot body 10, so that the locking and unlocking processes of the locking mechanism 30 will not be interfered by other components. During the opening process, after the movement of the locking mechanism 30 ends, the first buckle 41 will drive the second buckle 42 to rotate, so that the second buckle 42 is separated from the clamping table part 21a. During the closing process, after the second buckle 42 is clamped with the clamping table part 21a in place, the first buckle 41 will rotate and cooperate with the rotating part 51 and the linkage part 52 to drive the locking mechanism 30 to move to achieve locking.

[0093] The buckle mechanism includes: a first buckle 41 and a second buckle 42. The first buckle 41 is rotatably arranged and has a single rotation state and a linkage rotation state. The second buckle 42 is rotatably arranged and adjacent to the first buckle 41. When the first buckle 41 is in the single rotation state, the second buckle 42 is stationary. The first buckle 41 rotates relative to the second buckle 42. When the first buckle 41 is in the linkage rotation state, the first buckle 41 drives the second buckle 42 to rotate together.

[0094] like Figure 24 As shown, the buckle mechanism may only include a single buckle 47. In this solution, the portion where the single buckle 47 is buckled with the clamping platform 21a is provided with a roller 471, and the axis of the roller 471 extends in the horizontal direction. The roller 471 is in contact with the clamping platform 21a to reduce friction, and at the same time, a gentle convex arc surface is provided on the upper surface of the clamping platform 21a, and the cross-sectional shape of the arc surface is the same as the motion trajectory of the central axis of the roller 471 when the single buckle 47 rotates. In this way, the movement resistance of the single buckle 47 can be reduced and the cover body can be kept stable and not moved up.

[0095] like Figures 14 - 16 As shown, the first buckle 41 includes a first rotating plate 411 and a first hook body 412 arranged at the end of the first rotating plate 411, and the second buckle 42 includes a second rotating plate 421 and a second hook body 422 arranged at the end of the second rotating plate 421. The first rotating plate 411 and the second rotating plate 421 are arranged in a stacked manner, and there is an escape space 46 between the first hook body 412 and the second hook body 422, so that when the first buckle 41 rotates relative to the second buckle 42, the second hook body 422 avoids the first hook body 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. Since the escape space 46 is provided, the second buckle 42 can be stationary, and the first buckle 41 can rotate independently relative to the second buckle 42. The first buckle 41 is Figure 2d The status changes to Figure 3d When the first hook 412 of the first buckle 41 rotates to fit 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 status changes to Figure 4d status.

[0096] In this embodiment, the second buckle 42 is disposed near the first buckle 41 , and the second buckle 42 is closer to the longitudinal axis of the pot body 10 than the first buckle 41 .

[0097] In this embodiment, the first rotating plate 411 and the second rotating plate 421 are stacked. When the first hook body 412 of the first buckle 41 rotates to fit with the second hook body 422 of the second buckle 42, the first hook body 412 drives the second hook body 422 to rotate outwards together, and the first buckle 41 and the second buckle 42 change from Figure 3d the state of Figure 4d to the state of

[0098] Specifically, a first abutting surface 414 is provided on the first hook body 412, and a second abutting surface 424 is provided on the second hook body 422. When the first buckle 41 is in the state of linkage rotation, the first abutting surface 414 abuts against the second abutting surface 424, so that the first buckle 41 drives the second buckle 42 to rotate together. The above structure is simple and the movement process is easy to control.

[0099] As shown in Figure 22 and Figure 23 , the first abutting surface 414 is a first inclined surface, and the second abutting surface 424 is a second inclined surface. The above structure enables a relatively large contact area between the first buckle 41 and the second buckle 42 when the first buckle 41 drives the second buckle 42 to rotate together, improving the movement stability.

[0100] As shown in Figure 22 and Figure 23 , when the first buckle 41 is in the state of linkage rotation, the lowest point of the first hook body 412 is flush with the lowest point of the second hook body 422. The above structure can ensure that during the process of the pot body 10 and the cover assembly 20 switching from the unlocked state to the double-locked state, both the first hook body 412 and the second hook body 422 can be engaged with the clamping table portion 21a and the engagement is in place. It can avoid the situation that the two cannot be engaged in place due to interference during the reset process.

[0101] Of course, as a feasible implementation manner, when the first buckle is in the state of linkage rotation, the lowest point of the first hook body can also be higher than the lowest point of the second hook body. In this way, the first hook body and the second hook body can also be engaged in place during the reset process.

[0102] In an embodiment not shown in the figure, the first buckle may not be provided outside the second buckle. The first buckle and the second buckle are arranged side by side, and a linkage portion is provided between them. When the first buckle moves to a predetermined position, it drives the second buckle to move through the linkage portion. The linkage portion can be a structure such as a tension spring.

[0103] As a feasible implementation manner, the first buckle and the second buckle cooperate at the lower end. Specifically, the lower part of the second buckle extends towards the inner pot. When the user presses the unlocking operation part, the unlocking operation part pushes the first buckle to move inwards until the lower part of the unlocking operation part or the first buckle pushes the lower part of the second buckle, so that the first buckle and the second buckle move synchronously. The above manner can also achieve that when the first buckle drives the rotating part to rotate, the connection between the second buckle and the clamping table part can remain relatively stationary, and the first buckle continues to rotate to drive the second buckle to separate from the clamping table part, thereby realizing the unlocking operation.

[0104] As Figures 14 - 16 shown, the first hook body 412 has a first protruding dimension L1 protruding from the first rotating plate 411, and the second hook body 422 has a second protruding dimension L2 protruding from the second rotating plate 421. Among them, the first protruding dimension L1 and the second protruding dimension L2 satisfy L1≥1.5L2. The above structure can ensure the rotation amount of the first buckle 41 relative to the second buckle 42, and further ensure the locking stability of the locking mechanism 30 driven by the first buckle 41. Preferably, L1 = 1.5L2, or L1 = 2L, or L1 = 2.5L2.

[0105] As Figure 20 shown, the end of the first hook body 412 is a rounded corner structure 4121. Setting it as the rounded corner structure 4121 is convenient for controlling the matching position between the first buckle 41 and the clamping table part 21a. At the same time, when the first buckle 41 is in a single rotation state, it is not easy to interfere with other structures.

[0106] The first buckle 41 has a first rotation axis, and the second buckle 42 has a second rotation axis. In this embodiment, the first rotation axis and the second rotation axis are in the same vertical plane and are not collinear. The above setting is convenient for the first buckle 41 to drive the second buckle 42 to rotate in the linkage rotation state, and the movement trajectories of both are easy to control. In this embodiment, the first rotation axis is located below the second rotation axis.

[0107] In an implementation manner not shown in the figure, for the convenience of assembly, the first rotation axis and the second rotation axis are arranged collinearly.

[0108] As Figure 15 , Figure 16 and Figure 21As shown, the first rotating plate 411 includes a plate body 4111 and flanges 4112 provided on both sides of the plate body 4111. A first shaft portion 4113 is provided on the flanges 4112. The second rotating plate 421 is located in the accommodation space formed by the plate body 4111 and the flanges 4112 and is provided with a second shaft portion 4213. A first avoidance notch 4114 corresponding to the second shaft portion 4213 is also provided on the flanges 4112. The above structure enables the second buckle 42 to be received inside the first buckle 41, making the overall structure of the buckling assembly more compact. The above first shaft portion 4113 and second shaft portion 4213 can be pin shafts or shaft holes.

[0109] As Figure 15 , Figure 16 and Figure 21 shown, a first reset member connection portion 4115 is provided on the first rotating plate 411, and a second reset member connection portion 4215 is provided on the second rotating plate 421. The above structure facilitates the connection of the reset member.

[0110] As Figure 15 , Figure 16 and Figure 21 shown, a first reset member positioning portion 4116 is further provided on the first rotating plate, and a second reset member positioning portion 4216 is provided on the second rotating plate. The above structure is used to position the reset member, ensuring the normal operation of the reset member. In this embodiment, the first reset member positioning portion 4116 is a first positioning rib, and the second reset member positioning portion 4216 is a second positioning rib.

[0111] As Figure 16 shown, a second avoidance notch 4221 penetrating in the vertical direction is provided in the middle of the end of the second hook body 422. The second avoidance notch 4221 is also used to avoid the rotating member 51, making the overall structure more compact.

[0112] As Figure 15 and Figure 16 shown, the first rotating plate 411 has a first limiting surface 413 below the first hook body 412, and the second rotating plate 421 has a second limiting surface 423 below the second hook body 422. The first limiting surface 413 and the second limiting surface 423 are arranged flush. When the first buckle 41 and the second buckle 42 are in a static state, the first limiting surface 413 of the first buckle 41 abuts against the vertical plate 212, and the second limiting surface 423 of the second buckle 42 abuts against the vertical plate 212. The above first limiting surface 413 and second limiting surface 423 can respectively limit the positions of the first buckle 41 and the second buckle 42, enabling both to be firmly clamped to the buckling plane 21b.

[0113] As Figure 1As shown in the figure, the cooking appliance further includes a first reset member 44 disposed between the pot body 10 and the first buckle 41, and a second reset member 45 disposed between the pot body 10 and the second buckle 42. The first reset member 44 can keep the first buckle 41 in a vertical state, and the second reset member 45 can keep the second buckle 42 in a vertical state. When the lid assembly 20 is in the closed state, the first buckle 41 abuts against the rotating member 51 under the elastic force of the first reset member 44, and the second buckle 42 is clamped on the clamping table portion 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 buckle 41 can abut and cooperate with the vertical plate 212 of the clamping table portion 21a or the vertical plate on the pot body 10 below the vertical plate 212, so as to keep the first buckle 41 in a vertical state. Similarly, the second limiting surface 423 of the second buckle 42 can abut and cooperate with the vertical plate 212 of the clamping table portion 21a or the vertical plate on the pot body 10 below the vertical plate 212, so as to keep the second buckle 42 in a vertical state. When the first rotating plate 411 and the second rotating plate 421 are attached, the first limiting surface 413 and the second limiting surface 423 are coplanar.

[0114] As Figure 1 , Figure 9 and Figure 10 shown in the figure, the pot body 10 includes an inner pot 11, the inner pot 11 has a flanged edge 111 at the pot opening, the linkage member 52 includes a sliding plate, a sliding groove 521 is provided on the sliding plate, the locking mechanism 30 includes a mounting plate 31 and a caliper 32 provided at the bottom of the mounting plate 31, the caliper 32 can lock or unlock the flanged edge 111 at the pot opening, the moving direction of the sliding plate is perpendicular to the moving direction of the mounting plate 31, a limiting post 311 is provided on the mounting plate 31 and is inserted into the sliding groove 521, and the included angle α between the sliding 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 along the front-back direction of the lid assembly 20, and the mounting plate 31 moves along the left-right direction of the lid assembly 20. The smaller the included angle α, the smaller the distance the sliding plate moves when the mounting plate 31 moves the same distance. This makes the structure of the cooking appliance more compact. However, when the included angle α is greater than or equal to 25°, the sliding of the limiting post 311 in the sliding groove 521 is relatively smooth. Preferably, the included angle α can be 25°, 30°, 35° or 40°, etc.

[0115] In order to take into account the errors that occur during the processing, so that there can still be a certain relative movement between the sliding plate and the limiting post 311 after the locking mechanism 30 is locked in place. In the first embodiment, as Figure 9 and Figure 10As shown in the figure, an extension groove 522 communicating with the chute 521 is further provided on the sliding plate. The extension groove 522 is provided at one end of the chute 521 away from the rotating member 51, and the extending direction of the extension groove 522 is parallel to the moving direction of the sliding plate. Due to machining errors, after the locking mechanism 30 is locked in place, the sliding plate may not move in place. At this time, if the extension groove 522 is not provided, the sliding plate will continue to pull the limit post 311, resulting in a collision between the locking mechanism 30 and the flanging 111 of the pot mouth, causing damage to the flanging 111 of the pot mouth. For the solution with the extension groove 522 provided, after the locking mechanism 30 is locked in place, there can still be a certain relative movement between the sliding plate and the limit post 311, thus avoiding the collision between the locking mechanism 30 and the flanging 111 of the pot mouth.

[0116] As Figures 3a - 4e shown, when the buckle mechanism 40 is in the unlocked state (as Figures 4a - 4e ), there is a first distance L3 between the caliper 32 and the flanging 111 of the pot mouth (as Figure 4e ), when the buckle mechanism 40 is in the single-latching state (as Figures 3a - 3e ), there is a second distance L4 between the caliper 32 and the flanging 111 of the pot mouth (as Figure 3e ), and the second distance L4 is less than the first distance L3. The above structure ensures that there is always a distance between the caliper 32 and the flanging 111 of the pot mouth before the buckle mechanism 40 is latched with the clamping table portion 21a, avoiding the interference between the caliper 32 and the flanging 111 of the pot mouth caused by the upward movement of the cover assembly 20 relative to the cooker body 10 and resulting in the inability to close the cover.

[0117] As Figure 1 , Figures 9 - 11 shown, a surrounding plate 523 surrounding the outer periphery of the chute 521 is further provided on the sliding plate, and a rotatable friction-reducing member 312 is provided on the limit post 311. The friction-reducing member 312 is located inside the surrounding plate 523 and cooperates with the inner wall of the surrounding plate 523. The above structure can reduce the friction of the limit post 311 moving in the chute 521, and thus make the movement smoother. Preferably, the friction-reducing member 312 is a ball bearing. The above structure is simple and has a low cost.

[0118] In the first embodiment, the locking mechanism 30 has a floating position and a descending position. When the locking mechanism 30 is in the floating position and the descending position, the friction-reducing member 312 cooperates with the surrounding plate 523. In this way, regardless of whether there is upward pressure inside the inner pot 11, when the locking mechanism 30 is in the floating position or the descending position, it can ensure reducing the friction of the limit post 311 during the sliding process.

[0119] As Figure 12As shown, a receiving groove 511 is provided at the top of the rotating member 51, a linkage shaft 524 is provided at the front end of the linkage member 52, the linkage shaft 524 is located within the receiving groove 511, and the buckle mechanism 40 drives the bottom end of the rotating member 51. The above structure is easy to machine, and the cooperation between the rotating member 51 and the linkage member 52 is smoother when the rotating member 51 pulls the linkage member 52. A shaft is provided on the rotating member 51, and a shaft hole for installing the shaft is provided on the lining cover 21.

[0120] As Figure 1 , Figure 11 and Figure 17 As shown, the cover assembly 20 includes a lining cover 21 and a metal fixing plate 22 provided below the lining cover 21. The locking mechanism 30 includes a mounting plate 31 and a caliper 32 provided at the bottom of the mounting plate 31. The mounting plate 31 is movably provided on the metal fixing plate 22. The metal fixing plate 22 is floatingly mounted below the lining cover 21 through a connecting member 24, and a positioning structure is provided between the middle of the metal fixing plate 22 and the middle of the lining cover 21.

[0121] The metal fixing plate 22 is floatingly mounted below the lining cover 21 through the connecting member 24, so that there is a gap between the caliper 32 and the flanged edge 111 of the pot mouth in the up and down directions. When the inner pot 11 is in a hot state, there is a large amount of steam in the pot. When closing the lid, the cover assembly 20 will move upward and drive the caliper 32 to move upward. There is a gap between the caliper 32 and the flanged edge 111 of the pot mouth in the up and down directions, thus preventing the caliper 32 from pressing against the inner pot 11 and causing the lid not to close.

[0122] A bracket is provided on the above-mentioned metal fixing plate 22, and the mounting plate 31 is movably provided on the bracket. The above-mentioned lining cover 21 is prone to deformation when heated, and the middle of the lining cover 21 is prone to arching, especially the periphery is prone to warping. The positioning structure enables positioning between the middle of the metal fixing plate 22 and the middle of the lining cover 21, preventing the displacement of the metal fixing plate 22 caused by the deformation of the periphery of the lining cover 21, and thus ensuring that the locking mechanism 30 provided on the metal fixing plate 22 can move along a preset trajectory.

[0123] The lining cover 21 is provided with a connection hole for passing through the connecting member 24, and the connecting member 24 is floatingly mounted on the lining cover 21 through a spring and a gasket. In order to reduce the influence of the deformation of the lining cover 21 on the movement of the mounting plate 31, the gap between the connecting member 24 and the connection hole needs to be greater than 0.1 mm and less than or equal to 2 mm, preferably 0.5 mm.

[0124] A first guiding groove extending along the left and right directions of the lining cover 21 is provided on the bracket of the metal fixing plate 22. A second guiding groove extending along the left and right directions of the lining cover 21 is further provided on the lining cover 21. The limiting post 311 is sequentially passed through the first guiding groove, the second guiding groove and the sliding groove 521 from bottom to top. In the first embodiment, a face cover 25 is further provided above the lining cover 21.

[0125] As Figure 1 , Figure 11 and Figure 17 shown, the cover assembly 20 further includes an inner cover 23 disposed below the metal fixing plate 22. A temperature sensing member 231 is disposed at the center of the inner cover 23. The temperature sensing member 231 is connected to the lining cover 21. A through hole 221 for passing through the temperature sensing member 231 is disposed on the metal fixing plate 22. 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 lining cover 21, and the positioning post 222 is disposed on the metal fixing plate 22. In the above structure, through the cooperation of the temperature sensing member 231 and the through hole 221, the radial movement of the metal fixing plate 22 relative to the lining cover 21 is restricted. Then, through the cooperation of the positioning hole 214 and the positioning post 222, the anti-rotation of the metal fixing plate 22 and the lining cover 21 is achieved.

[0126] Of course, as a feasible implementation manner, the positioning post may not be separately provided, and the temperature sensing member 231 is used to achieve the corresponding function of the positioning post, that is, the positioning function is achieved only through the temperature sensing member 231. When the temperature sensing member 231 is disposed at the center of the inner cover 23, the temperature sensing member 231 and the through hole 221 need to be in anti-rotation cooperation. When the temperature sensing member 231 deviates from the center of the inner cover 23, the temperature sensing member 231 does not need to be in anti-rotation cooperation with the through hole 221.

[0127] As Figure 6 shown, to facilitate the installation of the third reset member 53, the cover assembly 20 includes a lining cover 21. A first hook 525 is disposed on the sliding plate, and a second hook 213 is disposed on the lining cover 21. The transmission mechanism 50 further 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. The third reset member 53 applies an elastic force to the sliding plate, causing the sliding plate to move backward, so that the locking mechanism 30 is in an unlocked state.

[0128] In the first embodiment, to simplify the structure and save costs, the cover assembly 20 includes a lining cover 21 and an inner cover 23 disposed below the lining cover 21. A non-opening rod that can float up and down is disposed on the inner cover 23, and a limiting hole for cooperating with the non-opening rod is disposed on the linkage member 52.

[0129] In the first embodiment, a position detection member (not shown in the figure) is disposed on the linkage member 52, which is used to detect the position of the linkage member 52 and thus detect whether the locking mechanism 30 is in a locked state or an unlocked state, so as to control the cooking program subsequently.

[0130] Alternatively, as a feasible implementation manner, a position detection member (not shown in the figure) is disposed on the buckle mechanism 40, which is used to detect the position of the linkage member 52 and thus detect whether the locking mechanism 30 is in a locked state or an unlocked state, so as to control the cooking program subsequently.

[0131] As Figure 7 and Figure 8 shown, the cover assembly 20 includes a lining cover 21, a clamping table portion 21a is provided on the lining cover 21. The clamping table portion 21a includes a transverse plate 211 and a vertical plate 212 connected to the transverse plate 211. The buckle mechanism 40 is clamped and matched with the top surface of the vertical plate 212. The rotating member 51 is located above the transverse plate 211 and behind the vertical plate 212. A first notch 2121 for avoiding the rotating member 51 is provided in the middle of the top surface of the vertical plate 212. The above structure enables the clamping table portion 21a to avoid the rotating member 51 to a certain extent through the first notch 2121, making the structure of the cooking appliance more compact.

[0132] The lid closing process and the lid opening process of the cooking appliance in the first embodiment will be described below.

[0133] The lid closing process of the cooking appliance in the first embodiment is as follows:

[0134] The first stage: As Figures 4a - 4e shown, the inclined surface of the lower surface of the clamping table portion 21a causes the first buckle 41 to move, and at the same time drives the second buckle 42 to move. At this time, the caliper 32 is in a fully open state, the limit post 311 is in the initial position, and the first distance between the caliper 32 and the flanging 111 of the pot mouth is L3 (designed clearance);

[0135] The second stage: As Figures 3a - 3e shown, when the cover assembly 20 reaches the set position, the second buckle 42 is reset under the action of the second reset member 45 and buckles on the buckling plane 21b of the clamping table portion 21a, so that the pot body 10 and the cover assembly 20 are buckled together to ensure that the cover assembly will not bounce or shake. At this time, the first buckle 41 does not touch the rotating member 51, the sliding plate does not move, the caliper 32 is in a fully open state, and the limit post 311 is in the initial position;

[0136] Furthermore, the first buckle 41 buckles on the buckling plane 21b of the clamping table portion 21a, the first buckle 41 touches the rotating member 51, and at the same time drives the sliding plate to move, forcing the caliper 32 to move, and the limit post 311 moves to the second position;

[0137] When the limit post 311 moves from the initial position to the second position, there is still a distance between the caliper 32 and the flanging 111 of the pot mouth to avoid contact between the caliper 32 and the flanging 111 of the pot mouth. The second distance therebetween is L4, and L4 < L3.

[0138] The third stage: As Figures 2a - 2d shown, the first buckle 41 contacts the bottom end of the rotating member 51, drives it to rotate, forces the sliding plate to slide, so that the caliper 32 clamps the flanging 111 of the pot mouth, and the limit post 311 is in the third position; The force F of the first reset member 44 > the force f of the third reset member 53.

[0139] The lid-opening process of the cooking appliance in the first embodiment is as follows:

[0140] The first stage: As Figures 2a - 2d , the limiting post 311 is in the third position, and the caliper 32 is located below the flanging 111 of the pot mouth;

[0141] The second stage: As Figures 3a - 3e , push the unlocking operation part 60, drive the first buckle 41 to move, and at the same time the third reset part 53 pulls the sliding plate to drive the caliper 32 to move. When the limiting post 311 moves to the second position, the second buckle 42 contacts the first buckle 41, and the second buckle 42 is still buckled on the buckling plane 21b. At this time, the caliper 32 is completely disengaged from the flanging 111 of the pot mouth;

[0142] The third stage: As Figures 4a - 4e , the first buckle 41 drives the second buckle 42 to move, so that the second buckle 42 disengages from the buckling plane 21b, and the lid assembly 20 is opened to complete the lid-opening.

[0143] As Figure 18 and Figure 19 shown, the difference between the cooking appliance in the second embodiment and the first embodiment lies only in the driving method for the unlocking operation part to achieve unlocking.

[0144] Specifically, in the second embodiment, the unlocking operation part 60 is movably arranged on the pot body 10, and the unlocking operation part 60 is drivingly cooperated with the rotating part 51 through the top-pushing structure 70. In the second embodiment, the unlocking operation part 60 does not cooperate with the buckle mechanism 40 but cooperates with the rotating part 51. When the lid assembly 20 needs to be opened, when the user presses the unlocking operation part 60, the unlocking operation part 60 can drive the rotating part 51 to rotate, so as to drive the locking mechanism 30 to unlock. At the same time, the rotation of the rotating part 51 can drive the buckle mechanism 40 to switch from the double-locking state to the single-locking state and then to the unlocking state. In the above process, first, the locking mechanism 30 is unlocked, and then the buckle mechanism 40 is separated from the clamping table part 21a, and finally the lid assembly 20 is opened. Preferably, the unlocking operation part 60 is an opening lid button and is arranged on the pot body 10 through the fixing ring 61. The unlocking operation part 60 pushes the bottom end of the top-pushing structure 70.

[0145] The top-pushing structure 70 includes multiple components. In the second embodiment, the top-pushing structure 70 includes a first top-pushing piece 71, a second top-pushing piece 72, and a third top-pushing piece 73. The first top-pushing piece 71 moves horizontally under the push of the unlocking operation part 60. The second top-pushing piece 72 is arranged on the pot body and can move vertically when the first top-pushing piece 71 moves horizontally. The third top-pushing piece 73 is arranged on the lid assembly 20 and can move upward when the second top-pushing piece 72 moves upward. Finally, the upward movement of the third top-pushing piece 73 drives the rotating part 51 to rotate.

[0146] As Figure 12 and Figure 15 shown, the buckle mechanism 40 is provided with a first avoidance portion 43 for avoiding the pushing structure 70, and the rotating member 51 is provided with a pushing inclined surface 512 for cooperating with the pushing structure 70 and a second avoidance portion 513 for avoiding the pushing structure 70. The above structure makes the overall layout of the cooking appliance more reasonable and the structure more compact.

[0147] As Figure 12 and Figure 15 shown, the first avoidance portion 43 is a second notch, the second avoidance portion 513 is a notch provided on the front surface of the rotating member 51, and the bottom of the pushing inclined surface 512 extends into the notch. The above structure is simple and easy to implement. The bottom of the pushing inclined surface 512 extending into the notch can reduce the size of the rotating member 51 while ensuring the matching dimension between the pushing structure 70 and the pushing inclined surface 512. Furthermore, the overall structure of the cooking appliance is made more compact.

[0148] In an embodiment not shown in the figure, the cooking appliance further includes an unlocking operation portion, which is movably provided on the cover assembly and is in driving cooperation with the rotating member. The above structure can also achieve the unlocking and locking of the cover assembly 20, which will not be elaborated here.

[0149] The cooking appliance of the present application is a pressure cooker, and of course it can also be an appliance with other functions such as a rice cooker, an electric slow cooker, a stir-fry machine, a food processor, etc.

[0150] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
