Description

Technical Field

[0001] The present invention relates to the field of small household appliances, and in particular, to a fastening assembly and a cooking appliance having the same. Background Art

[0002] In the related art, a cooking appliance includes a pot body and an upper cover disposed on the pot body. When the cooking appliance works, considering the safety of the user, the upper cover needs to be stably connected to the pot body. To ensure the connection stability of the upper cover, two sets of locking mechanisms are provided between the pot body and the upper cover. Among them, the first set of locking mechanisms is the locking formed between the lid lock of the upper cover and the heat preservation cover or the inner pot in the pot body through the engagement between the cover teeth and the pot teeth; the second set of locking mechanisms is the locking formed by the engagement between the clamping table on the upper cover and the hook on the pot body.

[0003] The first set of locking mechanisms needs to be unlocked by rotating the handle on the upper cover, and the second set of locking mechanisms needs to be unlocked by pressing the button on the cooker body. Therefore, when the user needs to open the lid, the user needs to first rotate the handle and then press the button to unlock, and the operation is relatively complicated, resulting in a poor user experience.

[0004] The Chinese utility model patent with the publication number of CN217696117U discloses a cooking appliance, which can solve the problem of relatively complicated operation when the user opens the lid. However, the solution of the above patent has the problems of laborious lid opening operation and unsmooth lid opening. Summary of the Invention

[0005] The main object of the present invention is to provide a fastening assembly and a cooking appliance having the same, so as to solve the problems of laborious lid opening operation and unsmooth lid opening in the related art.

[0006] To achieve the above object, according to one aspect of the present invention, there is provided a fastening assembly, including: a first hook, rotatably disposed, and having a single rotation state and a linkage rotation state; a second hook, rotatably disposed, and adjacent to the first hook, wherein when the first hook is in the single rotation state, the second hook is stationary, and the first hook rotates relative to the second hook; when the first hook is in the linkage rotation state, the first hook drives the second hook to rotate together.

[0007] Applying the technical solution of the present invention, the fastening assembly is arranged on the pot body and cooperates with the clamping table portion of the lid assembly and the rotating member of the transmission mechanism, so as to realize double locking and unlocking between the pot body and the lid assembly. Specifically, when the first hook and the second hook are stationary, the second hook is clamped with the clamping table portion, and the first hook abuts against the rotating member and pulls the linkage member to keep the locking mechanism in the locked state. At this time, the lid assembly and the pot body are double-locked, and in this state, the cooking appliance can perform pressure cooking. During the process from double locking to unlocking, the rotating member is driven to rotate by the first hook, or the first hook is driven to rotate by the rotating member. At this time, the second hook remains clamped with the clamping table portion, and the first hook continues to rotate and then switches to the unclamping state. When the fastening assembly is in the unclamping state, the second hook is separated from the clamping table portion, the locking mechanism is in the unlocked state, and the lid assembly and the pot body are unlocked. At this time, the lid assembly will switch from the closed state to the open state. In the prior art, for the solution in which the fastening assembly 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, which makes the locking mechanism prone to interference from other structures during the unlocking process, resulting in laborious operation and unsmooth opening of the lid. During the process from double locking to unlocking, when the first hook drives the rotating member to rotate or the rotating member drives the first hook to rotate, the second hook remains clamped with the clamping table portion. At this time, the position of the lid assembly relative to the pot body remains unchanged, and the rotation of the rotating member causes the locking mechanism to switch from the locked state to the unlocked state. In this way, the locking mechanism will not interfere with other structures in the lid assembly during movement, improving the smoothness of movement, and further making the opening and closing of the lid assembly smoother. Therefore, the technical solution of the present invention can solve the problems of laborious opening operation and unsmooth opening in the related art.

[0008] Further, the first hook includes a first rotating plate and a first hook body provided at the end of the first rotating plate, the second hook includes a second rotating plate and a second hook body provided at the end of the second rotating plate, and there is an avoidance space between the first hook body and the second hook body, so that when the first hook is in a single rotation state, the second hook body avoids the first hook body. The above structure can realize the single rotation of the first hook relative to the second hook and the synchronous movement between the two, with a simple structure, easy to implement, and the movement state is easy to control.

[0009] Further, a first abutting surface is provided on the first hook body, and a second abutting surface is provided on the second hook body. Among them, when the first hook is in the linkage rotation state, the first abutting surface abuts against the second abutting surface to drive the second hook to rotate together with the first hook. The above structure is simple and the movement process is easy to control.

[0010] Further, the first abutting surface is a first inclined surface, and the second abutting surface is a second inclined surface. The above structure makes the contact area between the first hook and the second hook larger when the first hook drives the second hook to rotate together, improving the movement stability.

[0011] Further, when the first hook is in a linkage rotation state, the lowest point of the first hook body is higher than or flush with the lowest point of the second hook body. The above structure can ensure that during the process of the pot body and the lid assembly switching from the unlocked state to the double-locked state, both the first hook body and the second hook body can be engaged with the clamping table portion and the engagement is in place.

[0012] Further, the first hook body has a first protruding dimension L1 protruding from the first rotating plate, and the second hook body 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 hook relative to the second hook, and further ensure the locking stability of the locking mechanism driven by the first hook.

[0013] Further, the end of the first hook body is a rounded corner structure. The rounded corner structure is provided to facilitate the control of the mating position between the first hook 41 and the clamping table portion.

[0014] Further, the first hook has a first rotation axis, and the second hook has a second rotation axis. Among them, the first rotation axis and the second rotation axis are arranged collinearly, or the first rotation axis and the second rotation axis are in the same vertical plane and are not collinear. The above setting facilitates assembly, or facilitates the first hook to drive the second hook to rotate when in the linkage rotation state, and the movement trajectories of both are easy to control.

[0015] Further, the first rotating plate includes a plate body and flanges provided on both sides of the plate body. The first shaft portion is provided on the flange, the second rotating plate is located in the accommodation space formed by the plate body and the flange and is provided with a second shaft portion, and a first avoidance notch corresponding to the second shaft portion is further provided on the flange. The above structure enables the second hook to be received inside the first hook, making the overall structure of the fastening assembly more compact.

[0016] Further, a first reset member connection portion is provided on the first rotating plate, and a second reset member connection portion is provided on the second rotating plate. The above structure facilitates the connection of the reset member.

[0017] Further, a first reset member positioning portion is further provided on the first rotating plate, and a second reset member positioning portion 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.

[0018] Further, the first rotating plate has a first limiting surface below the first hook body, and the second rotating plate has a second limiting surface below the second hook body. The first limiting surface and the second limiting surface are flush. The first limiting surface and the second limiting surface can respectively limit the positions of the first hook and the second hook, so that both are engaged with the fastening plane in place.

[0019] Further, a second avoidance notch penetrating in the up-down direction is provided in the middle of the end of the second hook body. The second avoidance notch is used to avoid the rotating member, making the overall structure more compact.

[0020] According to another aspect of the present invention, a cooking appliance is provided, including: 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 part is provided at the front part of the lid assembly, and the lid assembly has an open state and a closed state; a locking mechanism which is movably disposed on the lid assembly and has a locking state for locking the pot body and an unlocking state for unlocking the pot body; a buckling assembly which is rotatably disposed on the pot body, and the buckling assembly is the above-mentioned buckling assembly; a transmission mechanism including a rotating member rotatably disposed on the lid assembly and a linkage member disposed between the rotating member and the locking mechanism; wherein, when the first hook and the second hook of the buckling assembly are stationary, the second hook is clamped with the clamping table part, the first hook abuts against the rotating member and pulls the linkage member to keep the locking mechanism in the locking state, when the first hook drives the rotating member to rotate, the second hook keeps being clamped with the clamping table part, and the buckling assembly continues to rotate and then switches to an unclamping state.

[0021] By applying the technical solution of the present invention, since the buckling assembly can solve the problems of laborious opening operation and unsmooth opening in the related art, the cooking appliance including the buckling assembly can also solve the above problems.

[0022] Further, the cooking appliance further includes an unlocking operation part which is movably disposed on the pot body, and the unlocking operation part is in driving cooperation with the buckling assembly, or the unlocking operation part is in driving cooperation with the rotating member through a pushing structure. When it is necessary to open the lid assembly, when the user presses the unlocking operation part, the unlocking operation part can drive the buckling assembly or drive the rotating member through the pushing structure to rotate, so that the buckling assembly is switched from the double-clamping state to the unclamping state.

[0023] Further, the cooking appliance further includes an unlocking operation part which is movably disposed on the lid assembly, and the unlocking operation part is in driving cooperation with the rotating member. When it is necessary to open the lid assembly, when the user presses the unlocking operation part, the unlocking operation part can drive the rotating member to rotate, so that the buckling assembly is switched from the double-clamping state to the unclamping state.

[0024] Further, the cooking appliance further includes a first resetting member disposed between the pot body and the first hook and a second resetting member disposed between the pot body and the second hook.

[0066] 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 of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present invention.

[0067] It should be noted that the terms used herein are only for describing specific implementation manners and are not intended to limit the exemplary embodiments according to the present application. As used herein, 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 "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0068] 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 sake of 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 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: like reference numerals and letters denote like 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.

[0069] Such as Figures 1 to 8As shown in the figure, the fastening component of this embodiment includes: a first hook 41 and a second hook 42. Among them, the first hook 41 is rotatably arranged and has a single rotation state and a linkage rotation state. The second hook 42 is rotatably arranged and adjacent to the first hook 41. When the first hook 41 is in the single rotation state, the second hook 42 is stationary and the first hook 41 rotates relative to the second hook 42. When the first hook 41 is in the linkage rotation state, the first hook 41 drives the second hook 42 to rotate together.

[0070] Applying the technical solution of this embodiment, the fastening component is arranged on the pot body 10 and cooperates with the clamping table portion 21a of the cover body assembly 20 and the rotating member 51 of the transmission mechanism 50, so as to realize double locking and unlocking between the pot body 10 and the cover body assembly 20. Specifically, when the first hook 41 and the second hook 42 are stationary, the second hook 42 is clamped with the clamping table portion 21a, and the first hook 41 abuts against the rotating member 51 and pulls the linkage member 52 to keep the locking mechanism 30 in the locked state. At this time, the cover body assembly 20 and the pot body 10 are double locked, and in this state, the cooking appliance can perform pressure cooking. During the process from double locking to unlocking, the rotating member 51 is driven to rotate by the first hook 41, or the first hook 41 is driven to rotate by the rotating member 51. At this time, the second hook 42 remains clamped with the clamping table portion 21a. After that, the first hook 41 continues to rotate and then switches to the unclamping state. When the fastening component 40 is in the unclamping state, the second hook 42 is separated from the clamping table portion 21a, the locking mechanism 30 is in the unlocked state, and the cover body assembly 20 and the pot body 10 are unlocked. At this time, the cover body assembly 20 will switch from the closed state to the open state. In the prior art, for the solution where the fastening component cooperates with the clamping table portion and the locking mechanism at the same time, during the movement of the locking mechanism, the cover body assembly will move upward, which makes the locking mechanism prone to interference from other structures during the unlocking process, resulting in laborious operation and unsmooth opening of the cover. During the process from double locking to unlocking, when the first hook 41 drives the rotating member 51 to rotate or the rotating member 51 drives the first hook 41 to rotate, the second hook 42 remains clamped with the clamping table portion 21a. At this time, the position of the cover body assembly 20 relative to the pot body 10 remains unchanged. The rotating member 51 continues to rotate to make the locking mechanism 30 switch from the locked state to the unlocked state. In this way, the locking mechanism 30 will not interfere with other structures in the cover body assembly 20 during movement, improving the smoothness of movement, and further making the opening or closing of the cover body assembly 20 smoother. Therefore, the technical solution of this embodiment can solve the problems of laborious opening operation and unsmooth opening in the related art.

[0071] In this embodiment, the second hook 42 is arranged near the first hook 41, and the second hook 42 is closer to the longitudinal axis of the pot body than the first hook 41. Of course, in an embodiment not shown in the figure, the first hook 41 and the second hook 42 can be arranged side by side.

[0072] As shown in Figure 2 and Figure 3 In this embodiment, the first hook 41 includes a first rotating plate 411 and a first hook body 412 disposed at the end of the first rotating plate 411. The second hook 42 includes a second rotating plate 421 and a second hook body 422 disposed at the end of the second rotating plate 421. There is an avoidance space 46 between the first hook body 412 and the second hook body 422, so that when the first hook 41 is in a separate rotating state, the second hook body 422 avoids the first hook body 412. The above structure can realize the separate rotation of the first hook 41 relative to the second hook 42 and the synchronous movement between the two. The structure is simple and easy to implement, and the movement state is easy to control. Due to the setting of the avoidance space 46, the second hook 42 can be stationary, and the first hook 41 can rotate separately relative to the second hook 42. The first hook 41 rotates from Figure 10d the state of Figure 11d to the state of

[0073] In this embodiment, the first rotating plate 411 and the second rotating plate 421 are stacked, and the second rotating plate 421 is on one side in the thickness direction of the first rotating plate 411. When the first hook body 412 of the first hook 41 rotates to fit with the second hook body 422 of the second hook 42, the first hook body 412 drives the second hook body 422 to rotate outward together (toward the direction away from the longitudinal axis of the cooking appliance). The first hook 41 and the second hook 42 rotate from Figure 11d the state of Figure 12d to the state of

[0074] 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 hook 41 is in a linked rotation state, the first abutting surface 414 abuts against the second abutting surface 424, so that the first hook 41 drives the second hook 42 to rotate together. The above structure is simple and the movement process is easy to control.

[0075] In other embodiments not shown in the figure, the first hook body can drive the second hook body to move in other ways, such as setting a linkage part between the two, such as a pull rod, a pull rope or an elastic member. At this time, the first hook can also drive the second hook to rotate together.

[0076] As shown in Figure 7 and Figure 8 the first abutting surface 414 is a first inclined surface, and the second abutting surface 424 is a second inclined surface. The above structure makes the contact area between the first hook 41 and the second hook 42 larger when they rotate together, improving the movement stability.

[0077] As shown in Figure 7 andFigure 8 As shown, when the first hook 41 is in the linkage rotation state, 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 lid 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. This can avoid the situation where interference occurs during the reset process and the engagement cannot be achieved.

[0078] Of course, as a feasible implementation manner, when the first hook is in the linkage rotation state, the lowest point of the first hook body can also be higher than the lowest point of the second hook body. This can also achieve the in-place engagement of the first hook body and the second hook body during the reset process.

[0079] As Figure 6 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 hook 41 relative to the second hook 42, and further ensure the locking stability of the locking mechanism 30 driven by the first hook 41. Preferably, L1 = 1.5L2, or L1 = 2L, or L1 = 2.5L2.

[0080] As Figure 4 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 cooperation position of the first hook 41 and the clamping table portion 21a. At the same time, when the first hook 41 is in the single rotation state, it is not easy to interfere with other structures.

[0081] The first hook 41 has a first rotation axis, and the second hook 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 hook 41 to drive the second hook 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.

[0082] In an implementation manner not shown in the figure, for the convenience of assembly, the first rotation axis and the second rotation axis are collinearly arranged.

[0083] As Figure 2As shown in the figure, 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 within 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 hook 42 to be received inside the first hook 41, making the overall structure of the fastening assembly more compact. The above-mentioned first shaft portion 4113 and second shaft portion 4213 can be pin shafts or shaft holes. An avoidance portion 43 is provided on the plate body 4111.

[0084] As Figure 2 and Figure 3 shown in the figure, 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. The first reset member connection portion 4115 includes two connection shafts extending outward in opposite directions, and the second reset member connection portion 4215 includes two connection shafts extending inward in opposite directions.

[0085] As Figure 2 and Figure 3 shown in the figure, 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.

[0086] As Figure 14 and Figure 15 shown in the figure, 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 horizontal plate 211 and a vertical plate 212 connected to the horizontal plate 211. The fastening assembly 40 is clamped and matched with the top surface of the vertical plate 212. The rotating member 51 is located above the horizontal 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.

[0087] As Figure 9As shown, the cover assembly 20 includes a lining cover 21 and a metal fixing plate 22 disposed below the lining cover 21. The locking mechanism 30 includes a mounting plate 31 and a caliper 32 disposed at the bottom of the mounting plate 31. The mounting plate 31 is movably disposed on the metal fixing plate 22. The metal fixing plate 22 is floatingly mounted below the lining cover 21 through a connecting member. A positioning structure is provided between the middle of the metal fixing plate 22 and the middle of the lining cover 21. The cover assembly 20 includes a lining cover 21 and an inner cover 23 disposed below the lining cover 21. An anti-opening rod that can float up and down is provided on the inner cover 23. A limiting hole that cooperates with the anti-opening rod is provided on the linkage member 52.

[0088] As Figure 9 , Figure 10b , Figure 11b and Figure 12b shown, the cooking 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 disposed 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 that penetrates through the sliding groove 521 is provided on the mounting plate 31. The included angle 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°.

[0089] As Figure 3 shown, a second avoiding notch 4221 that penetrates in the up and down direction is provided in the middle of the end of the second hook body 422. The second avoiding notch 4221 is also used to avoid the rotating member 51, making the overall structure more compact.

[0090] As Figure 1 shown, the first rotating plate 411 has a first limiting surface 413 located below the first hook body 412. The second rotating plate 421 has a second limiting surface 423 located below the second hook body 422. The first limiting surface 413 and the second limiting surface 423 are flush. When the first buckle hook 41 and the second buckle hook 42 are in a static state, the first limiting surface 413 of the first buckle hook 41 abuts against the vertical plate 212, and the second limiting surface 423 of the second buckle hook 42 abuts against the vertical plate 212. The above-mentioned first limiting surface 413 and second limiting surface 423 can respectively limit the positions of the first buckle hook 41 and the second buckle hook 42, so that both are clamped in place with the buckling plane 21b.

[0091] It should be noted that the first limiting surface 413 and the second limiting surface 423 can be flush only when the cover assembly 20 is in the closed state. When the first buckle hook 41 is in the linkage rotation state and when the cover assembly 20 is in the open state, the first limiting surface 413 and the second limiting surface 423 can be non-flush.

[0092] Of course, for the convenience of control, when the cover body assembly 20 is in the closed cover state, the open cover state, and the first hook 41 is in the linkage rotation state, the first limiting surface 413 and the second limiting surface 423 are both flush.

[0093] The present application also provides a cooking appliance, as Figures 9 to 15 shown. Embodiment 1 of the cooking appliance according to the present application includes: a pot body 10, a cover body assembly 20, a locking mechanism 30, a fastening assembly 40, and a transmission mechanism 50. Among them, 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 hinged 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 cover state. 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; the fastening assembly 40 is rotatably disposed on the pot body 10, and the fastening assembly is the above-mentioned fastening assembly. The transmission mechanism 50 includes a rotating member 51 rotatably disposed on the cover body assembly 20 and a linkage member 52 disposed between the rotating member 51 and the locking mechanism 30; wherein, when the first hook 41 and the second hook 42 of the fastening assembly 40 are stationary, the second hook 42 is clamped with the clamping table portion 21a, and the first hook 41 abuts against the rotating member 51 and pulls the linkage member 52 to keep the locking mechanism 30 in the locking state. When the first hook 41 drives the rotating member 51 to rotate or the rotating member 51 drives the first hook 41 to rotate, the second hook 42 remains clamped with the clamping table portion 21a, and the first hook 41 continues to rotate and then switches to the unclamping state.

[0094] Applying the technical solution of the present invention, since the fastening assembly can solve the problems of laborious opening operation and unsmooth opening in the related art, the cooking appliance including the fastening assembly can also solve the above problems.

[0095] In Embodiment 1, the cooking appliance further includes an unlocking operation portion 60. The unlocking operation portion 60 is movably disposed on the pot body 10, and the unlocking operation portion 60 is in driving cooperation with the fastening assembly 40. When it is necessary to open the cover body assembly 20, when the user presses the unlocking operation portion 60, the unlocking operation portion 60 can drive the fastening assembly 40 to switch from the double clamping state to the unclamping state. Preferably, the unlocking operation portion 60 is an opening cover button and is disposed on the pot body 10 through a fixing ring 61. The unlocking operation portion 60 pushes against the bottom end of the fastening assembly 40.

[0096] As Figure 9As shown in the figure, the cooking appliance further includes a first reset member 44 disposed between the pot body 10 and the first hook 41, and a second reset member 45 disposed between the pot body 10 and the second hook 42. The first reset member 44 can keep the first hook 41 in a vertical state, and the second reset member 45 can keep the second hook 42 in a vertical state. When the lid assembly 20 is in the closed state, the first hook 41 abuts against the rotating member 51 under the elastic force of the first reset member 44, and the second hook 42 is clamped on the clamping 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 cooking appliance further includes a third reset member 53 disposed on the lining cover 21, preferably 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.

[0097] The lid closing process and the lid opening process of the cooking appliance in the first embodiment will be described below.

[0098] The lid closing process of the cooking appliance in the first embodiment is as follows:

[0099] The first stage: As Figures 12a to 12e , the inclined surface on the lower surface of the clamping portion 21a causes the first hook 41 to move. When it moves to the set position, the first inclined surface matches the second inclined surface. The lowest point on the first hook 41 ( Figure 4 the position indicated by the rounded corner structure 4121) is at the same height as the engaging surface on the second hook 42. At this time, the first hook 41 drives the second hook 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 (design clearance);

[0100] The second stage: As Figures 11a to 11e , when the lid assembly 20 reaches the set position, the second hook 42 is reset and buckled on the engaging plane 21b of the clamping portion 21a under the action of the second reset member 45, so that the pot body 10 and the lid assembly 20 are buckled together to ensure that the lid assembly will not bounce or shake. At this time, the first hook 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; the width of the engaging plane 21b on the clamping portion 21a is smaller than the width of the engaging plane of the second hook 42, that is, the second protruding dimension L2;

[0101] Furthermore, the first hook 41 is buckled on the engaging plane 21b of the clamping portion 21a. The first hook 41 touches the rotating member 51 and drives the sliding plate to move at the same time, forcing the caliper 32 to move, and the limit post 311 moves to the second position;

[0102] 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 prevent contact between the caliper 32 and the flanging 111 of the pot mouth. The second distance between them is L4, and L4 < L3.

[0103] The third stage: As Figures 10a to 10d , the first hook 41 contacts the bottom end of the rotating member 51, drives it to rotate, forces the slide 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.

[0104] The lid-opening process of the cooking appliance in the first embodiment is as follows:

[0105] The first stage: As Figures 10a to 10d , the limit post 311 is in the third position, and the caliper 32 is located below the flanging 111 of the pot mouth;

[0106] The second stage: As Figures 11a to 11e , push the unlocking operation part 60, drive the first hook 41 to move. At the same time, the third reset member 53 pulls the slide plate to drive the caliper 32 to move. When the limit post 311 moves to the second position, the second hook 42 contacts the first hook 41, and the second hook 42 is still latched on the latching plane 21b. At this time, the caliper 32 is completely disengaged from the flanging 111 of the pot mouth; during the above process, the second hook 42 does not move, the lining cover 21 does not move either, and the frictional force of the movement of the first hook 41 is small, so the unlocking operation part 60 can be pushed with a very small force;

[0107] The third stage: As Figures 12a to 12e , the first hook 41 drives the second hook 42 to move, so that the second hook 42 disengages from the latching plane 21b, and the lid assembly 20 is opened to complete the lid-opening.

[0108] It should be noted that in other embodiments, when the second hook is stationary, the movement of the first hook can cause the locking mechanism not to be fully unlocked. When the first hook is in the linkage rotation state, the first hook continues to drive the second hook to move. Before or at the same time when the second hook separates from the clamping table, the locking mechanism continues to complete the remaining unlocking stroke.

[0109] As Figure 16 and Figure 17 shown, the difference between the cooking appliance in the second embodiment and the first embodiment lies only in the driving manner of the unlocking operation part to achieve unlocking.

[0110] 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 engaged with the rotating part 51 through the pushing structure 70. In the second embodiment, the unlocking operation part 60 does not cooperate with the fastening component 40 but cooperates with the rotating part 51. When the cover body 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 that the locking mechanism 30 can be unlocked, and at the same time, the rotation of the rotating part 51 can drive the fastening component 40 to switch from the double-locking state to the unlocking state. In the above process, the locking mechanism 30 is unlocked first, and then the fastening component 40 is separated from the clamping table part 21a, and finally the cover body 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 the bottom end of the pushing structure 70.

[0111] The pushing structure 70 includes multiple components. In the second embodiment, the pushing structure 70 includes a first pushing piece 71, a second pushing piece 72, and a third pushing piece 73. The first pushing piece 71 moves horizontally under the push of the unlocking operation part 60, the second pushing piece 72 is arranged on the pot body and can move vertically when the first pushing piece 71 moves horizontally. The third pushing piece 73 is arranged on the cover body assembly 20 and can move upward when the second pushing piece 72 moves upward. Finally, the upward movement of the third pushing piece 73 drives the rotating part 51 to rotate.

[0112] In an embodiment not shown in the figure, the cooking appliance further includes an unlocking operation part, which is movably arranged on the cover body assembly and is drivingly engaged with the rotating part. When the user triggers the unlocking operation part, the unlocking operation part directly drives the rotating part to rotate.

[0113] 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 stew pot, a stir-fry machine, a cooking machine, etc.

[0114] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, so it cannot be understood as a limitation on the protection scope of the present invention; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0115] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper", etc. can be used here to describe the spatial positional relationship of a device or feature shown in the figure with other devices or features. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figure for the device. For example, if the device in the drawing is inverted, a device described as "above" or "over" other devices or structures will then be positioned "below" or "under" the other devices or structures. Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the corresponding explanations for the spatial relative descriptions used here will be made accordingly.

[0116] In addition, it should be noted that the use of terms such as "first", "second", etc. to define components is only for the convenience of differentiating the corresponding components. Without additional statements, the above terms have no special meanings, and thus should not be construed as limiting the protection scope of the present invention.

[0117] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
