Description

Technical Field

[0001] The utility model relates to the technical field of small household appliances, and in particular to a cooking utensil. Background Art

[0002] In the related art, pressure cooking appliances generally have cover teeth on the lid assembly and pot teeth on the pot assembly. During the cooking process, the cover teeth and the pot teeth are aligned to meet the pressure requirements during pressure cooking.

[0003] To ensure smooth opening and closing of the lid assembly, the cover teeth must be offset from the pot teeth to prevent interference between the two teeth, which could prevent the lid assembly from being pressed down or lifted smoothly. Therefore, the cover teeth must be able to switch between a position aligned with the pot teeth and a position offset from them. To achieve this, an operating element is typically provided on the lid assembly, which the user can manipulate to move the cover teeth.

[0004] However, the above-mentioned operating member will occupy a certain space above the cover assembly, which makes the space above the cover assembly available for arranging the operating panel smaller. The control panel can only be set on the pot body assembly or a smaller control panel can be set on the cover assembly. Both of these settings are inconvenient for users. Utility Model Content

[0005] The main purpose of the present invention is to provide a cooking appliance to solve the problem in the related art that the setting mode of the control panel affects the user experience.

[0006] In order to achieve the above-mentioned objectives, the present invention provides a cooking utensil, comprising: a pot body assembly, including a shell and a pot body arranged in the shell; an operating assembly, arranged on the shell and exposed outwardly from the shell; a lower rotating coupling, arranged on the shell, the operating assembly drivingly cooperates with the lower rotating coupling and can drive the lower rotating coupling to rotate; a cover body assembly, which can be opened and closed and is arranged above the pot body assembly, the cover body assembly includes a mounting cover and a first locking member arranged on the mounting cover, the first locking member is provided with cover teeth, and the first locking member has a locked position and an unlocked position; an upper rotating coupling, which is arranged on the cover body assembly and coupled with the lower rotating coupling to rotate synchronously with the lower rotating coupling, and the upper rotating coupling can drive the first locking member to switch between the locked position and the unlocked position.

[0007] Using the technical solution of the present invention, an operating assembly is positioned on the pot body assembly, and a lower rotating coupling and an upper rotating coupling are disposed between the operating assembly and the first locking member of the lid assembly. When opening or closing the lid, the user operates the operating assembly located on the pot body assembly. The driving force from the operating assembly is transmitted to the first locking member via the lower rotating coupling and the upper rotating coupling, thereby driving the first locking member to switch between a locked position and an unlocked position. This arrangement allows the operating assembly for user operation to be positioned on the pot body assembly, freeing up the space above the lid assembly. This allows for a larger control panel to be positioned on the lid assembly, resulting in a larger control panel interface. The user no longer needs to reach to the side of the pot body assembly to operate the control panel, making it more convenient for the user. Therefore, the technical solution of the present application effectively addresses the problem in the related art where the control panel configuration affects the user experience.

[0008] Furthermore, the pot body assembly is provided with a second locking member, which includes a locking hook and has a locked position and an unlocked position. The operating assembly can drive the second locking member to switch from the locked position to the unlocked position. The operating assembly can drive both the first locking member to switch positions and the second locking member to switch positions, achieving functional integration, a simple structure, and user-friendly operation.

[0009] Furthermore, the operating assembly includes an operating member and a transmission member, wherein the operating member is exposed outwardly from the housing, and includes an operating portion and a transmission portion. The transmission member includes a transmission mating portion capable of mating with the transmission portion, and the transmission mating portion and the transmission portion have a first mating state and a second mating state. In the first mating state, the operating member drives the lower rotating coupling member to rotate via the transmission member. In the second mating state, the operating member and the transmission member are disengaged from the driving mating state and can drive the second locking member to switch from a fastened position to a released position. The provision of two mating states between the transmission portion and the transmission mating portion allows a user to sequentially drive the first locking member and the second locking member when operating the operating member. Based on the use of the same structure to drive the first and second locking members to switch positions, the sequential order of the operations of the first and second locking members is further ensured.

[0010] Furthermore, the operating portion includes an operating knob, the transmission portion includes a transmission rod offset from the axis of the operating knob and extending inward, and the transmission mating portion includes a vertically extending transmission slot having a linkage section and an escape section. In a first mating state, the transmission rod is disposed within the linkage section and abuts against the side wall of the linkage section to drive the transmission member to move. In a second mating state, the transmission rod is disposed within the escape section and separated from the side wall of the escape section. The above arrangement enables the user to perform a single operation to achieve step-by-step control of the first locking member and the second locking member, thereby facilitating user use. The mating of the transmission rod and the transmission slot has the advantage of a simple structure.

[0011] Furthermore, the transmission member is located between the second locking member and the operating knob. A transmission slot extends through the transmission member in the inward-outward direction of the housing. The second locking member has a concave relief surface corresponding to the linkage section and a matching inclined surface corresponding to the matching section. The matching inclined surface extends toward the outside of the housing, away from the concave relief surface. The transmission slot is a through-slot structure. The second locking member, transmission member, and operating knob are arranged side by side, allowing the transmission rod to pass through the transmission member to drive the second locking member. This, in turn, makes the internal structure of the pot body assembly compact while enabling the driving operations of the first and second locking members to be performed step by step.

[0012] Furthermore, the housing is provided with a mounting opening, and the pot body assembly further includes a mounting seat provided at the mounting opening, the mounting seat being provided with an arcuate guide groove, and the transmission rod is provided within the arcuate guide groove. The transmission rod is provided within the arcuate guide groove, and the arcuate guide groove can guide the transmission rod and limit the extreme position.

[0013] Furthermore, the lower rotating coupler has a rotation range of between 240° and 360°; and / or the lower rotating coupler and the upper rotating coupler have a unique mating state. During the lid closing process, by properly setting the posture of the lower rotating coupler, when the lid assembly is pressed down, the upper rotating coupler can only engage with the lower rotating coupler when it rotates to a specific angle. At this point, the pot teeth and the lid teeth are properly misaligned, ensuring that the lid assembly can be smoothly pressed down.

[0014] Furthermore, the housing includes a middle plate, on which a lower mounting tube is disposed. The lower rotating coupling member includes a first coupling post extending from top to bottom within the lower mounting tube and engaging with a stopper on the upper surface of the lower mounting tube, and a second coupling post extending from bottom to top within the lower mounting tube and engaging with a stopper on the lower surface of the lower mounting tube. By configuring the lower rotating coupling member as a separate first coupling post and a second coupling post, with the first coupling post and the second coupling post respectively engaging with the upper and lower surface stops of the lower mounting tube, the lower rotating coupling member can be prevented from being moved downward or pulled upward by the cover assembly during the process of being pressed down or lifted, thereby ensuring the positional stability of the lower rotating coupling member.

[0015] Furthermore, the second coupling post is provided with a lower driven tooth, and the operating assembly is provided with a lower driving tooth that meshes with the lower driven tooth. Alternatively, the cooking appliance further includes a lower locking member disposed within the housing, which locks the operating assembly when the lid assembly is not positioned on the pot assembly and unlocks the operating assembly when the lid assembly is positioned on the pot assembly. The mutually meshing lower driven tooth and lower driving tooth are provided between the operating assembly and the second coupling post, enabling the operating assembly to drive the lower rotating coupling member to rotate, thereby providing the advantages of a simple structure and reliable transmission. When the lid assembly is opened, the lower locking member locks the operating assembly, maintaining both the operating assembly and the lower rotating coupling member in the state in which the lid assembly and the pot assembly were separated, thereby preventing a user from misoperating the operating assembly and affecting subsequent lid closing and alignment operations.

[0016] Furthermore, the mounting cover is provided with an upper mounting tube, and the upper rotating coupling includes a third coupling post that extends from top to bottom within the upper mounting tube and engages with a stop on the upper surface of the upper mounting tube, and a fourth coupling post that extends from bottom to top within the upper mounting tube and engages with a stop on the lower surface of the upper mounting tube. Providing the upper rotating coupling with separate third and fourth coupling posts, and with the third and fourth coupling posts respectively engaging with the upper and lower stops of the upper mounting tube, prevents the upper rotating coupling from moving upward or downward when the cover assembly is pressed down or lifted, thereby ensuring the positional stability of the upper rotating coupling.

[0017] Furthermore, the first locking member includes a locking cover and a guide rod disposed above the locking cover. The cooking appliance further includes a transmission rocker disposed between the upper rotating coupler and the guide rod. The guide rod passes through the transmission rocker. Rotation of the upper rotating coupler drives the transmission rocker, which in turn drives the guide rod, thereby switching the first locking member between a locked position and an unlocked position. The transmission rocker cooperates with the guide rod on the locking cover to drive the locking cover to rotate for position switching, thereby having the advantage of a simple structure.

[0018] Furthermore, the transmission rocker is provided with a rotation hole, a guide slot, and an upper driven tooth. The upper rotating coupling is provided with an upper driving tooth that meshes with the upper driven tooth. The guide slot is located between the rotation hole and the upper driven tooth. The guide rod is disposed within the guide slot. When the upper rotating coupling rotates, the transmission rocker is driven to swing about the center of the rotation hole. And / or, the cooking appliance further includes an upper locking member disposed within the lid assembly. When the lid assembly is not positioned on the pot assembly, the upper locking member locks the transmission rocker. When the lid assembly is positioned on the pot assembly, the upper locking member unlocks the transmission rocker. The engagement between the upper driven tooth and the upper driving tooth enables the transmission rocker to swing when the upper rotating coupling rotates, thereby providing advantages of a simple structure and reliable transmission. When the lid assembly is opened, the upper locking member locks the transmission rocker, ensuring that the transmission rocker, the upper rotating coupling, and the first locking member remain in the state in which the lid assembly and the pot assembly were separated, thereby preventing a user from accidentally rotating the lid and locking it, thereby affecting subsequent lid closing and alignment operations.

It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0050] like Figures 1 to 4As shown, the present application provides a cooking appliance. An embodiment of the cooking appliance of the present application includes: a pot body assembly 10 , an operating assembly 20 , a lower rotating coupling 30 , a cover assembly 40 and an upper rotating coupling 50 . Among them, the pot body assembly 10 includes a shell 11 and a pot body 12 arranged in the shell 11; the operating assembly 20 is arranged on the shell 11 and exposed to the outside of the shell 11; the lower rotating coupling 30 is arranged on the shell 11, and the operating assembly 20 drives and cooperates with the lower rotating coupling 30 and can drive the lower rotating coupling 30 to rotate; the cover assembly 40 is openably arranged above the pot body assembly 10, and the cover assembly 40 includes a mounting cover 41 and a first locking member 42 arranged on the mounting cover 41, and the first locking member 42 is provided with a cover tooth 421, and the first locking member 42 has a locked position and an unlocked position; the upper rotating coupling 50 is arranged on the cover assembly 40 and coupled with the lower rotating coupling 30 to rotate synchronously with the lower rotating coupling 30, and the upper rotating coupling 50 can drive the first locking member 42 to switch between the locked position and the unlocked position.

[0051] Using the technical solution of this embodiment, the operating assembly 20 is positioned on the pot body assembly 10, and a lower rotating coupling 30 and an upper rotating coupling 50 are disposed between the operating assembly 20 and the first locking member 42 of the lid assembly 40. To open or close the lid, the user operates the operating assembly 20 located on the pot body assembly 10. The driving force from the operating assembly 20 is transmitted to the first locking member 42 via the lower rotating coupling 30 and the upper rotating coupling 50, thereby driving the first locking member 42 to switch between a locked position and an unlocked position. This arrangement allows the operating assembly 20, which is operated by the user, to be positioned on the pot body assembly 10. This frees up the space above the lid assembly 40, allowing for a larger control panel to be positioned on the lid assembly. This results in a larger control panel interface and eliminates the need for the user to reach to the side of the pot body assembly 10 to operate the control panel, facilitating user experience. Therefore, the technical solution of this embodiment effectively addresses the problem in related art where the control panel placement method affects the user experience.

[0052] like Figure 3 As shown, the first locking member 42 is provided with a cover tooth 421, and correspondingly, the pot body 12 on the pot body assembly 10 is provided with a pot tooth 121. When the first locking member 42 is in the locked position, the cover tooth 421 is located below the pot tooth 121 and is arranged opposite to the pot tooth 121; when the first locking member 42 is in the unlocked position, the cover tooth 421 and the pot tooth 121 are offset.

[0053] like Figure 1 and Figure 2As shown, the pot body assembly 10 is provided with a second locking member 60, which includes a locking hook 61. The second locking member 60 has a locked position and an unlocked position. The operating assembly 20 can drive the second locking member 60 to switch from the locked position to the unlocked position. The second locking member 60 includes a locking hook 61, which can engage with a hook portion 415 fixed to the lid assembly 40. Specifically, when the second locking member 60 is in the locked position, the locking hook 61 and the hook portion 415 are in a hooked state; when the second locking member 60 is in the unlocked position, the locking hook 61 is separated from the hook portion 415. By providing both the first locking member 42 and the second locking member 60, dual locking of the lid assembly 40 and the pot body assembly 10 can be achieved. The operating assembly 20 can drive both the first locking member 42 and the second locking member 60 to switch positions, achieving functional integration, a simple structure, and user-friendly operation.

[0054] like Figure 2 、 Figure 8 and Figure 10 As shown, the operating assembly 20 includes an operating member 21 and a transmission member 22. The operating member 21 is exposed outside the housing 11. The operating member 21 includes an operating portion 211 and a transmission portion 212. The transmission member 22 has a transmission engagement portion 221 that can cooperate with the transmission portion 212. The transmission engagement portion 221 and the transmission portion 212 have a first engagement state and a second engagement state. In the first engagement state, the operating member 21 drives the lower rotating coupling 30 to rotate via the transmission member 22. In the second engagement state, the operating member 21 and the transmission member 22 are disengaged from the driving engagement state and can drive the second locking member 60 from the engaged position to the disengaged position. The two engagement states between the transmission portion 212 and the transmission engagement portion 221 allow the user to sequentially drive the first locking member 42 and the second locking member 60 when operating the operating member 21. Based on the use of the same structure to drive the first locking member 42 and the second locking member 60 to switch positions, the sequence of the operations of the first locking member 42 and the second locking member 60 is further guaranteed.

[0055] It should be noted that in this embodiment, the operating portion 211 extends outward from the housing 11 to facilitate user operation. In an embodiment not shown in the figure, the operating member may not protrude outward from the housing. In this case, an operating recess for the user to insert his hand to operate the operating portion can be provided on the housing.

[0056] Specifically, for the cover assembly 40 that flips open, a torsion spring with a relatively large torsional force is generally provided at the hinge position of the cover assembly 40 and the pot body assembly 10, so that the cover assembly 40 can be stably maintained in the open state. Due to the provision of the above-mentioned torsion spring, when the cover assembly 40 is opened and when the cover assembly 40 is closed, the action sequence of the first locking member 42 and the second locking member 60 is different. When closing the cover, it is necessary to first switch the second locking member 60 to the snapping position to engage with the snap hook portion 415, and then switch the first locking member 42 from the unlocked position to the locked position. The initial locking between the cover assembly 40 and the pot body assembly 10 is achieved through the snapping between the second locking member 60 and the snap hook portion 415, and the torsional force of the torsion spring is overcome, so that when the first locking member 42 switches from the unlocked position to the locked position, the cover teeth 421 are located below the pot teeth 121 and there is a certain distance between the pot teeth 121. The gap between the pot teeth 121 and the cover teeth 421 is avoided, so that friction between the pot teeth 121 and the cover teeth 421 causes greater resistance when the user operates the operating part 211; when opening the cover, it is necessary to first switch the first locking member 42 from the locked position to the unlocked position, and then switch the second locking member 60 from the engaged position to the unfastened position, so as to avoid the situation where the pot teeth 121 and the cover teeth 421 collide under the action of the torsion spring after the engagement of the second locking member 60 and the hook portion 415 is released, and the user operates the operating part 211 and causes greater resistance.

[0057] like Figure 2 、 Figure 8 and Figure 10As shown, the operating portion 211 includes an operating knob 2111, the transmission portion 212 includes a transmission rod 2121 that is offset from the axis of the operating knob 2111 and extends inwardly, and the transmission mating portion 221 includes a vertically extending transmission slot having a linkage section 2211 and an avoidance section 2212. In a first mating state, the transmission rod 2121 is disposed within the linkage section 2211 and abuts against the side wall of the linkage section 2211 to drive the transmission member 22 to move. In a second mating state, the transmission rod 2121 is disposed within the avoidance section 2212 and is separated from the side wall of the avoidance section 2212. The operating portion 211 includes an operating knob 2111, and a user can rotate the operating knob 2111 to switch the positions of the first locking member 42 and the second locking member 60, thereby facilitating user operation. The transmission part 212 includes a transmission rod 2121 that is arranged to deviate from the axis of the operating knob 2111. When the operating knob 2111 is rotated, the transmission rod 2121 makes an arc or circular motion centered on the axis of the operating knob 2111. The transmission rod 2121 is inserted into the transmission long slot. The transmission long slot can avoid the movement of the transmission rod 2121 along the extension direction of the transmission long slot. The movement of the transmission rod 2121 perpendicular to the extension direction of the transmission long slot can drive the transmission member 22 to move. By setting the transmission long slot as a two-section structure, wherein, when the transmission rod 2121 is located in the linkage section 2211, the operating member 21 drives the lower rotating coupling member 30 through the transmission member 22 to drive the first locking member 42 to switch positions; when the transmission rod 2121 is located in the avoidance section 2212, the side wall of the avoidance section 2212 avoids the transmission rod 2121, so that the transmission member 22 and the lower rotating coupling member 30 remain stationary, and the transmission rod 2121 drives the second locking member 60 to switch positions, so that the user can perform one operation (rotating the operating knob 2111) to achieve step-by-step control of the first locking member 42 and the second locking member 60, which is convenient for users to use. The combination of the transmission rod 2121 and the transmission long slot has the advantage of simple structure.

[0058] like Figures 6 to 8 As shown, in this embodiment, the operating portion 211 is a rotating member, and the transmission member 22 is a translating member. In an embodiment not shown in the figure, both the operating portion and the transmission member can be movable members. Specifically, the operating portion is a push button structure, and the user can push the operating portion to move along an "L"-shaped trajectory through the push button. The mating groove on the transmission member is a long groove structure extending in the vertical direction. When the cover needs to be opened, the user first pushes the push button to move along the horizontal section of the "L"-shaped trajectory. At this time, the operating member can drive the transmission member to move synchronously. Then, the user pushes the push button to move along the vertical section of the "L"-shaped trajectory. At this time, the operating member can continue to move and engage with the second locking member, while the transmission member remains stationary.

[0059] like Figure 2 、 Figure 4 and Figure 10The transmission member 22 is located between the second locking member 60 and the operating knob 2111. A transmission slot extends through the transmission member 22 in the inward-outward direction of the housing 11. The second locking member 60 has a concave relief surface 62 corresponding to the linkage section 2211 and a matching slope 63 corresponding to the matching section 2212. The matching slope 63 extends toward the outside of the housing 11, away from the concave relief surface 62. The transmission slot is a through-slot structure. The second locking member 60, transmission member 22, and operating knob 2111 are arranged side by side, allowing the transmission rod 2121 to pass through the transmission member 22 to drive the second locking member 60, thereby making the internal structure of the pot body assembly 10 compact. When the second locking member 60 is in the state of being locked, the locking member 211 is unlocked and the locking member 211 is unlocked. The above arrangement enables the driving operation of the first locking member 42 and the driving operation of the second locking member 60 to be performed in steps.

[0060] like Figure 11 As shown, the second locking member 60 is a swinging member and includes a locking hook 61, a relief concave surface 62, a mating bevel 63, and a shaft portion 64. The locking hook 61 is located on the upper side of the shaft portion 64, the relief concave surface 62 and the mating bevel 63 are located on the lower side of the shaft portion 64, and the mating bevel 63 is located below the relief concave surface 62. Two mounting plates 1125 are provided on the middle plate 112 of the housing 11. The two mounting plates 1125 are respectively provided with fixing holes. The ends of the shaft portion 64 are respectively inserted into the two fixing holes, allowing the second locking member 60 to swing around the shaft portion 64. The locking hook 61 can be extended upward through the middle plate 112 and engage with the hook portion 415 fixed to the cover assembly 40.

[0061] Of course, in an embodiment not shown in the figures, the second locking member may also be a translation member.

[0062] In this embodiment, the pot body assembly 10 also includes a third reset member (for example, a spring) arranged between the shell 11 and the second locking member 60. The third reset member applies a force to the second locking member 60 so that the second locking member 60 remains in the engaged position, that is, in the natural state, the second locking member 60 always remains in the engaged position. When the user drives the second locking member 60 through the operating assembly 20, the second locking member 60 will switch from the engaged position to the unlocked position.

[0063] At least one of the second locking member 60 and the hook portion 415 is provided with a guiding inclined surface. In this way, when the cover assembly 40 is pressed downwardly toward the pot body assembly 10, under the action of the guiding inclined surface, the second locking member 60 overcomes the force of the third restoring member and switches from the fastened position to the unfastened position; when the hook portion 415 passes over the locking hook 61 of the second locking member 60, the second locking member 60 switches from the unfastened position to the fastened position under the action of the third restoring member, thereby realizing automatic fastening between the cover assembly 40 and the pot body assembly 10.

[0064] like Figure 1 、 Figure 2 and Figure 8 As shown, the housing 11 is provided with a mounting opening 111. The pot assembly 10 also includes a mounting base 13 disposed at the mounting opening 111. The operating member 21 is disposed through the mounting base 13. The mounting base 13 is provided with an arcuate guide groove 131, and the transmission rod 2121 is disposed within the arcuate guide groove 131. Mounting the operating member 21 to the pot assembly 10 via the mounting base 13 offers the advantage of a simple structure. The transmission rod 2121 is disposed within the arcuate guide groove 131, which provides guidance for the transmission rod 2121 and limits its position.

[0065] like Figures 8 to 11 As shown, the arc-shaped guide groove 131 has a first groove section 1311 corresponding to the linkage section 2211 and a second groove section 1312 corresponding to the avoidance section 2212. The operating assembly 20 also includes a first reset member 24 arranged between the mounting seat 13 and the operating member 21. When the transmission rod 2121 is located in the first groove section 1311, the first reset member 24 is separated from the transmission rod 2121. When the transmission rod 2121 is located in the second groove section 1312, the first reset member 24 applies a reset force to the transmission rod 2121 so that the transmission rod 2121 rotates into the first groove section 1311. When the cover opening operation is completed and the user no longer operates the operating member 21, the transmission rod 2121 located in the second groove section 1312 will move into the first groove section 1311 under the action of the first reset member 24. At this time, the transmission rod 2121 no longer presses against the matching inclined surface 63, and the second locking member 60 is reset to the locking position. When the user closes the cover subsequently, the second locking member 60 can be automatically locked with the hook portion 415 on the cover body assembly 40.

[0066] like Figure 8 and Figure 9 As shown, the first reset member 24 is a torsion spring. The mounting seat 13 is provided with a sinking mounting portion 132 that sinks toward the inner side of the pot body assembly 10. The sinking mounting portion 132 includes a central area 1321 located in the middle of the mounting seat 13 and a reset area 1322 located outside the central area 1321 and connected to the second slot section 1312. The sinking mounting portion 132 has a second side wall 1324 away from the first slot section 1311 and a first side wall 1323 close to the first slot section 1311. The torsion spring includes a torsion spring body 241 and A first torsion arm 242 and a second torsion arm 243 are provided at both ends of the torsion spring body 241. The torsion spring body 241 is located in the central area 1321. When the transmission rod 2121 is located in the first groove section 1311, the first torsion arm 242 is pressed against the first side wall 1323, and the second torsion arm 243 is pressed against the second side wall 1324. When the transmission rod 2121 is located in the second groove section 1312, the second torsion arm 243 is pressed against the second side wall 1324, and the first torsion arm 242 is pressed against the transmission rod 2121. Specifically, when the transmission rod 2121 is located in the first slot section 1311, the first torsion arm 242 and the second torsion arm 243 respectively press against the first side wall 1323 and the second side wall 1324, and the torsion spring does not apply a force to the transmission rod 2121; when the transmission rod 2121 is located in the second slot section 1312, the first torsion arm 242 breaks away from the first side wall 1323 and presses against the transmission rod 2121, and the second torsion arm 243 presses against the second side wall 1324. As the transmission rod 2121 gradually moves away from the first slot section 1311, the first torsion arm 242 is separated from the first side wall 1323 and presses against the transmission rod 2121, and the second torsion arm 243 presses against the second side wall 1324. The transmission rod 2121 drives the first torsion arm 242 to gradually approach the second torsion arm 243, and the restoring force applied by the torsion spring to the transmission rod 2121 becomes increasingly stronger. When the second locking member 60 and the hook portion 415 are disengaged and the user releases the operating knob 2111, the torsion spring applies a restoring force to the transmission rod 2121, causing the transmission rod 2121 to move out of the second slot 1312. At this time, the first torsion arm 242 abuts against the first side wall 1323 and no longer applies a restoring force to the transmission rod 2121. The configuration of the sunken mounting portion 132 provides installation space for the torsion spring. When the transmission rod 2121 moves into the second slot 1312, the first torsion arm 242 applies a restoring force to the transmission rod 2121, allowing it to return to the first slot 1311, thereby preventing the automatic fastening function of the second locking member 60 from being affected.

[0067] like Figure 8 and Figure 9 As shown, a stopper 133 is provided at one end of the second side wall 1324 close to the operating knob 2111 , and the stopper 133 can stop and limit the second torsion arm 243 to prevent the second torsion arm 243 from being separated from the mounting seat 13 .

[0068] Specifically, a mounting convex ring is provided in the central area 1321, and the torsion spring body 241 is sleeved on the mounting convex ring. The operating knob 2111 is also provided with a mounting shaft 2112, which is passed through the center hole of the mounting convex ring.

[0069] In this embodiment, the central angle of the arc-shaped guide groove 131 is between 30° and 180°, thereby making the rotation range of the operating knob 2111 between 30° and 180°. In this way, when the user rotates the operating knob 2111, only one rotation is required to meet the rotation requirement, without having to rotate the knob multiple times, which further facilitates the user's use.

[0070] Preferably, the central angle of the arc-shaped guide groove 131 can be 30°, 60°, 90°, 120°, 150°, or 180°. Designers can choose from the above angles as long as it can meet the requirements of driving the first locking member 42 and the second locking member 60 to switch positions and the angle that the user needs to rotate the operating knob 2111 is as small as possible.

[0071] In this embodiment, both the lower rotating coupler 30 and the upper rotating coupler 50 are rotating members, and the rotation range of the lower rotating coupler 30 is between 240° and 360°. This configuration prevents the lower rotating coupler 30 from having more than two mating positions with the upper rotating coupler 50 within the rotation range of the lower rotating coupler 30. This prevents situations where the lower rotating coupler 30 and the upper rotating coupler 50 can mate, but the pot teeth 121 and the cover teeth 421 partially overlap when the cover assembly 40 is pressed downward, affecting further downward pressure on the cover assembly 40. Alternatively, situations where the lower rotating coupler 30 and the upper rotating coupler 50 can mate, but after the user rotates the operating knob 2111 to a set rotation angle, the pot teeth 121 and the cover teeth 421 partially align, resulting in insufficient pressure bearing capacity between the pot teeth 121 and the cover teeth 421. Preferably, the rotation range of the lower rotating coupler 30 can be 240°, 270°, 300°, 330°, or 360°.

[0072] In this embodiment, the lower rotating coupler 30 and the upper rotating coupler 50 have a unique mating state. This "unique mating state" means that when the lower rotating coupler 30 is in a certain position, the upper rotating coupler 50 can only mate with the lower rotating coupler 30 at a specific angle within a 360-degree range. When the upper rotating coupler 50 is rotated to other angles, it cannot mate with the lower rotating coupler 30. In this way, during the process of closing the lid, by reasonably setting the posture of the lower rotating coupling 30, when the cover body assembly 40 is pressed down, the upper rotating coupling 50 can only dock with the lower rotating coupling 30 when it is rotated to a specific angle. At this time, the pot teeth 121 and the cover teeth 421 are just misaligned, ensuring that the cover body assembly 40 can be pressed down smoothly; at the same time, after the user subsequently rotates the operating knob 2111 according to the set operation amount, the lower rotating coupling 30 and the upper rotating coupling 50 can just drive the first locking member 42 to move to the position where the cover teeth 421 are opposite to the pot teeth 121, that is, drive the first locking member 42 to switch from the unlocked position to the locked position.

[0073] like Figure 1 、 Figure 2 、 Figure 4 、 Figure 13 and Figure 15 As shown, a plug-in structure is provided between the lower rotating coupler 30 and the upper rotating coupler 50. The plug-in structure includes a coupling groove 311 for plug-in anti-rotation fit and a coupling protrusion 521. The coupling groove 311 is provided on one of the lower rotating coupler 30 and the upper rotating coupler 50, and the coupling protrusion 521 is provided on the other of the lower rotating coupler 30 and the upper rotating coupler 50. The plug-in anti-rotation fit of the coupling groove 311 and the coupling protrusion 521 achieves docking between the lower rotating coupler 30 and the upper rotating coupler 50 and enables them to rotate synchronously, which has the advantages of simple structure and reliable transmission.

[0074] Specifically, the coupling groove 311 and the coupling protrusion 521 have the same predetermined cross-section, which can be a D-shape, a trapezoid, a T-shape, or a non-equilateral triangle. By setting the predetermined cross-section to the aforementioned shape, the coupling groove 311 and the coupling protrusion 521 can achieve a unique mating state between the lower rotating coupling 30 and the upper rotating coupling 50 when mated.

[0075] like Figure 1 、 Figure 2 、 Figure 5 and Figure 13As shown, the housing 11 includes a middle plate 112, on which a lower mounting tube 1121 is disposed. The lower rotating coupling member 30 includes a first coupling post 31 extending from top to bottom through the lower mounting tube 1121 and engaging with a stopper on the upper surface of the lower mounting tube 1121, and a second coupling post 32 extending from bottom to top through the lower mounting tube 1121 and engaging with a stopper on the lower surface of the lower mounting tube 1121. The lower rotating coupling member 30 is configured as a separate first coupling post 31 and a second coupling post 32, with the first coupling post 31 and the second coupling post 32 respectively engaging with the stoppers on the upper and lower surfaces of the lower mounting tube 1121. This prevents the cover assembly 40 from moving the lower rotating coupling member 30 downward or upward during the process of being pressed down or lifted, thereby ensuring the positional stability of the lower rotating coupling member 30.

[0076] Specifically, if Figure 13 As shown, the first coupling column 31 and the second coupling column 32 are connected in a non-rotatable manner via a non-rotatable plug-in structure.

[0077] like Figure 1 As shown, the housing 11 further includes an outer shell 113 and a bottom shell 114 . The middle plate 112 is disposed above the outer shell 113 , the bottom shell 114 is disposed below the outer shell 113 , and the mounting port 111 is disposed on the outer shell 113 .

[0078] like Figure 10 and Figure 14 As shown, a second guide post 1124 is provided below the middle plate 112, and a guide slot 223 extending in the transverse direction is provided on the transmission member 22. The second guide post 1124 is provided from top to bottom within the guide slot 223 to guide the movement of the transmission member 22. In this embodiment, there are two second guide posts 1124 and two guide slots 223, and the two second guide posts 1124 and the two guide slots 223 are provided in a one-to-one correspondence.

[0079] like Figure 2 、 Figure 10 and Figure 13 As shown, the second coupling post 32 is provided with a lower driven tooth 321, and the operating assembly 20 is provided with a lower driving tooth 23 that meshes with the lower driven tooth 321. The mutually meshing lower driven tooth 321 and lower driving tooth 23 are provided between the operating assembly 20 and the second coupling post 32, enabling the operating assembly 20 to drive the lower rotating coupling member 30 to rotate, thereby having the advantages of simple structure and reliable transmission.

[0080] Specifically, in this embodiment, the lower driving teeth 23 are mounted on the transmission member 22 and are a rack structure, while the lower driven teeth 321 are gear structures. The travel range of the lower driving teeth 23 is less than or equal to the baseline circumference of the lower driven teeth 321. By ensuring that the travel range of the lower driving teeth 23 is less than or equal to the baseline circumference of the lower driven teeth 321, the lower driving teeth 23 can only drive the lower driven teeth 321 through a maximum rotation (i.e., a maximum rotation of 360°) during movement, thereby ensuring that the rotation range of the lower rotary coupling 30 is less than or equal to 360°.

[0081] Specifically, in this embodiment, the moving range of the lower driving tooth 23 (ie, the moving range of the transmission member 22 ) is determined by the radius and the central angle of the arc-shaped guide groove 131 .

[0082] It should be noted that, in this embodiment, the lower driven tooth 321 has a plurality of tooth portions extending along the vertical direction, and the above-mentioned “baseline circumference of the lower driven tooth 321 ” refers to the circumference of the circle where the base lines of the plurality of tooth portions are located.

[0083] like Figure 2 and Figure 12 As shown, the cooking appliance further includes a lower locking member 70 disposed within the housing 11. When the lid assembly 40 is not covered on the pot assembly 10, the lower locking member 70 locks the operating assembly 20. When the lid assembly 40 is covered on the pot assembly 10, the lower locking member 70 unlocks the operating assembly 20. When the lid assembly 40 is opened, the lower locking member 70 can lock the operating assembly 20, so that the operating assembly 20 and the lower rotating coupling 30 remain in the state when the lid assembly 40 is separated from the pot assembly 10, preventing the user from accidentally operating the operating assembly 20 and affecting the subsequent lid closing and alignment operations.

[0084] Specifically, in this embodiment, the lower locking member 70 locks the operating assembly 20 by locking the transmission member 22 .

[0085] like Figure 10 and Figure 12As shown, the lower locking member 70 includes a first trigger protrusion 71, a lock hook 72 and a fourth reset member. The first trigger protrusion 71 extends upward from the shell 11, and the lock hook 72 is located below the first trigger protrusion 71 and can be locked with the transmission member 22. The fourth reset member applies an upward force to the first trigger protrusion 71 and / or the lock hook 72 to keep the lower locking member 70 in the position of locking the transmission member 22. When the cover assembly 40 is not covered on the pot body assembly 10, the lower locking member 70 is moved as a whole to the position of locking the transmission member 22 under the action of the fourth reset member, and the lock hook 72 locks the transmission member 22 to limit the movement of the transmission member 22 in the lateral direction, and the first trigger protrusion 71 extends to a greater height of the shell 11; after the cover assembly 40 is covered on the pot body assembly 10, the cover assembly 40 presses down the first trigger protrusion 71 and overcomes the force of the fourth reset member (at this time, the first trigger protrusion 71 can extend to a smaller height of the shell 11 or not extend from the shell 11), so that the lower locking member 70 is moved downward as a whole to the position of unlocking the transmission member 22, so that the transmission member 22 can move.

[0086] like Figure 12 and Figure 14 As shown, a trigger through-hole 1122 is provided on the middle plate 112 for the first trigger protrusion 71 to pass upward; a first guide column 1123 is also provided below the middle plate 112, and the lower locking member 70 also includes a main body plate, the first trigger protrusion 71 is arranged above the main body plate, and the lock hook 72 is arranged below the main body plate. A guide hole 73 is provided on the main body plate, and the first guide column 1123 extends downward and passes through the guide hole 73 downward. The fourth reset member is a compression spring that is sleeved on the first guide column 1123 and located below the main body plate. The lower locking member 70 also includes a mounting plate connected to the bottom of the middle plate 112 and extending to the bottom of the first guide column 1123. The two ends of the compression spring respectively press against the main body plate and the mounting plate to apply an upward pressing force to the main body plate.

[0087] like Figure 10 and Figure 12 As shown, the lock hook 72 has a lock slot 721 opening upward, and the transmission member 22 is provided with a lock column 222. When the lower locking member 70 is in a position to unlock the transmission member 22, the lock column 222 is located above the lock slot 721. When the lower locking member 70 is in a position to lock the transmission member 22, the lock column 222 is located in the lock slot 721. The lock hook 72 having the lock slot 721 cooperates with the lock column 222 to lock the transmission member 22, thereby achieving the advantages of simple structure and reliable locking.

[0088] like Figure 1 、 Figure 4 、 Figure 5 and Figure 15As shown, the mounting cover 41 is provided with an upper mounting cylinder 411, and the upper rotating coupling 50 includes a third coupling post 51 that passes through the upper mounting cylinder 411 from top to bottom and engages with a stopper on the upper surface of the upper mounting cylinder 411, and a fourth coupling post 52 that passes through the upper mounting cylinder 411 from bottom to top and engages with a stopper on the lower surface of the upper mounting cylinder 411. The upper rotating coupling 50 is provided as a separate third coupling post 51 and fourth coupling post 52, and the third coupling post 51 and fourth coupling post 52 respectively engage with the upper and lower surface stops of the upper mounting cylinder 411. This can prevent the upper rotating coupling 50 from moving upward or downward when the cover assembly 40 is pressed down or lifted, thereby ensuring the positional stability of the upper rotating coupling 50.

[0089] Specifically, if Figure 15 As shown, the third coupling column 51 and the fourth coupling column 52 are connected in a non-rotatable manner via a non-rotatable plug-in structure.

[0090] like Figure 1 、 Figure 4 、 Figure 6 and Figure 7 As shown, the first locking member 42 includes a locking cover 422 and a guide rod 423 disposed above the locking cover 422. The cooking appliance also includes a transmission rocker 80 disposed between the upper rotating coupler 50 and the guide rod 423. The guide rod 423 penetrates the transmission rocker 80. When the upper rotating coupler 50 rotates, the transmission rocker 80 swings, which in turn swings the guide rod 423, thereby switching the first locking member 42 between the locked and unlocked positions. The cooperation between the transmission rocker 80 and the guide rod 423 on the locking cover 422 drives the locking cover 422 to rotate for position switching, thus having the advantage of a simple structure.

[0091] In an embodiment not shown in the figures, the first locking member may also be a caliper structure.

[0092] like Figure 1 、 Figure 4 、 Figure 6 、 Figure 7 and Figure 16As shown, the transmission rocker 80 is provided with a rotation hole 81, a guide slot 82, and an upper driven tooth 83. The upper rotating coupler 50 is provided with an upper driving tooth 53 that meshes with the upper driven tooth 83. The guide slot 82 is located between the rotation hole 81 and the upper driven tooth 83. The guide rod 423 extends through the guide slot 82. When the upper rotating coupler 50 rotates, the transmission rocker 80 swings about the center of the rotation hole 81. The engagement between the upper driven tooth 83 and the upper driving tooth 53 enables the transmission rocker 80 to swing when the upper rotating coupler 50 rotates. This provides the advantages of a simple structure and reliable transmission. The guide slot 82 is located between the rotation hole 81 and the upper driven tooth 83, meaning that the rotation hole 81 is positioned away from the upper driven tooth 83. This allows the transmission rocker 80 to swing, thereby switching the first locking member 42 between the locked and unlocked positions, by simply rotating the upper rotating coupler 50 by a relatively small angle.

[0093] like Figure 4 As shown, an arcuate groove 412 is provided on the mounting cover 41 , and the guide rod 423 is upwardly passed through the arcuate groove 412 and the guide groove 82 in sequence. The arcuate groove 412 can guide the movement of the guide rod 423 and limit the extreme position.

[0094] like Figure 4 As shown, a support base 413 is provided on the mounting cover 41 , and the rotation hole 81 of the transmission rocker 80 is sleeved on the support base 413 , so that the transmission rocker 80 can swing around the center of the support base 413 .

[0095] In this embodiment, the rotation hole 81 and the upper driven tooth 83 are respectively provided at both ends of the transmission rocker 80. Preferably, the transmission rocker 80 is as long as possible, so that the upper rotary coupling 50 can drive the transmission rocker 80 to swing a small angle to drive the locking cover 422 to rotate a predetermined angle.

[0096] like Figure 1 、 Figure 4 、 Figure 16 and Figure 17 As shown, the cooking appliance further includes an upper locking member 90 disposed within the lid assembly 40. When the lid assembly 40 is not mounted on the pot assembly 10, the upper locking member 90 locks the transmission rocker 80. When the lid assembly 40 is mounted on the pot assembly 10, the upper locking member 90 unlocks the transmission rocker 80. When the lid assembly 40 is opened, the upper locking member 90 locks the transmission rocker 80, so that the transmission rocker 80, the upper rotating coupling member 50, and the first locking member 42 remain in the state in which the lid assembly 40 and the pot assembly 10 are separated, thereby preventing a user from accidentally rotating the locking cover 422 and affecting subsequent lid closing and alignment operations.

[0097] Specifically, if Figure 4 、 Figure 16 and Figure 17As shown, the upper locking member 90 includes a second trigger protrusion 91 extending downward, a mounting tube 92 arranged side by side with the second trigger protrusion 91, a locking block 93 arranged at the upper end of the second trigger protrusion 91 and extending downward through a cantilever structure, and a second reset member 94 arranged in the mounting tube 92. The second reset member 94 is a compression spring, and the two ends of the second reset member 94 respectively press against the lower wall surface of the mounting tube 92 and the surface cover 43; a lock hole 84 is provided on the transmission rocker arm 80, and a perforated structure is provided on the mounting cover 41 for the second trigger protrusion 91 to pass downward. When the cover assembly 40 is not covered on the pot body assembly 10, the upper locking member 90 moves downward as a whole under the action of the second restoring member 94, so that the locking block 93 is inserted into the locking hole 84 of the transmission rocker 80, thereby restricting the transmission rocker 80 from swinging; when the cover assembly 40 is covered on the pot body assembly 10, the pot body assembly 10 will push upward against the second triggering protrusion 91, so that the upper locking member 90 moves upward as a whole and the locking block 93 leaves the locking hole 84. At this time, the transmission rocker 80 can swing.

[0098] like Figure 4 As shown, the mounting cover 41 is further provided with a mounting post 414, which is inserted into a mounting hole in the lower wall of the mounting cylinder 92 to guide the upper locking member 90 in its vertical movement. The second return member 94 is sleeved on the mounting post 414 and is located in the annular space formed by the mounting post 414 and the mounting cylinder 92.

[0099] The following describes the movement and transmission relationship of various components during the opening and closing of the lid in conjunction with the specific structure of the cooking appliance:

[0100] In the open state:

[0101] The second locking member 60 is maintained in the engaged position under the action of the third reset member; the lower locking member 70 is maintained in the position of locking the transmission member 22 under the action of the fourth reset member, and the lock column 222 on the transmission member 22 is located in the lock groove 721 of the lock hook 72, limiting the movement of the transmission member 22 in the lateral direction; the transmission rod 2121 is maintained at the intersection of the first groove section 1311 and the second groove section 1312 under the action of the first torsion arm 242 of the first reset member 24; the upper locking member 90 moves downward under the action of the second reset member 94 and causes the transmission rocker 80 to stay in a position that keeps the first locking member 42 in the position where the cover tooth 421 and the pot tooth 121 are misaligned (that is, the first locking member 42 is maintained in the unlocked position).

[0102] During the lid closing process:

[0103] The user first presses down the cover assembly 40 so that the cover assembly 40 is close to the pot body assembly 10. Since the first locking member 42 is kept in the position where the cover teeth 421 and the pot teeth 121 are misaligned under the action of the upper locking member 90, the cover assembly 40 can be pressed down smoothly. During the process of pressing the cover assembly 40 down, the pot body assembly 10 presses the upper locking member 90 upward, so that the upper locking member 90 switches from the position of locking the transmission rocker 80 to the position of unlocking the transmission rocker 80, and the cover assembly 40 presses the lower locking member 70 downward, so that the lower locking member 70 switches from the position of locking the transmission member 22 to the position of unlocking the transmission member 22, and the second locking member 60 and the hook portion 415 on the cover assembly 40 are automatically fastened under the action of the guide slope and the third reset member. At this time, the transmission rod 2121 of the operating member 21 is located at the intersection of the first groove section 1311 and the second groove section 1312 and at the intersection of the linkage section 2211 and the avoidance section 2212.

[0104] Then the user can use the operating part 21 to drive the cover teeth 421 and the pot teeth 121 to align. Figure 8 The operating knob 2111 is rotated clockwise, and the transmission rod 2121 moves clockwise along the first slot section 1311. At this time, the transmission rod 2121 and the Figure 10 The right side wall of the middle linkage section 2211 cooperates with the driving member 22 to move Figure 10 The lower driving tooth 23 on the transmission member 22 engages with the lower driven tooth 321 on the second coupling column 32, driving the second coupling column 32, the first coupling column 31, the fourth coupling column 52 and the third coupling column 51 to move synchronously along Figure 6 and Figure 7 The third coupling column 51 rotates counterclockwise, and the upper driving tooth 53 of the third coupling column 51 engages with the upper driven tooth 83 on the transmission rocker 80, driving the transmission rocker 80 to swing along the center of the rotating hole 81. Figure 6 and Figure 7 During the swinging process of the transmission rocker arm 80, the first locking member 42 is driven to rotate by the cooperation between the guide rod 423 and the guide groove 82, so that the first locking member 42 is rotated from the position where the cover teeth 421 and the pot teeth 121 are staggered to the position where the cover teeth 421 and the pot teeth 121 are directly opposite (that is, the first locking member 42 is rotated to the locked position) to meet the pressure bearing requirement during the cooking process.

[0105] Through the above steps, when closing the lid, the second locking member 60 and the hook portion 415 are first engaged between the lid assembly 40 and the pot body assembly 10, and then the lid teeth 421 and the pot teeth 121 are aligned.

[0106] In the closed state:

[0107] The second locking member 60 is kept in the buckled position by the action of the third reset member; the lower locking member 70 is kept in the position of unlocking the transmission member 22 due to the downward pressure of the cover assembly 40, and the upper locking member 90 is kept in the position of unlocking the transmission rocker 80 due to the upward pressure of the pot assembly 10; the transmission rod 2121 is located at Figure 8 The rightmost end of the middle arc-shaped guide groove 131 , that is, the operating knob 2111 is located at the right-hand limit position; the cover teeth 421 and the pot teeth 121 are kept in facing positions.

[0108] During the opening process:

[0109] The user first drives the cover teeth 421 and the pot teeth 121 to dislocate by the operating member 21, and then Figure 8 The operating knob 2111 is rotated counterclockwise, and the transmission rod 2121 moves counterclockwise along the first slot section 1311. At this time, the transmission rod 2121 and the Figure 10 The left side wall of the middle linkage section 2211 cooperates with the driving member 22 to move Figure 10 The lower driving tooth 23 on the transmission member 22 engages with the lower driven tooth 321 on the second coupling column 32, driving the second coupling column 32, the first coupling column 31, the fourth coupling column 52 and the third coupling column 51 to move synchronously along Figure 6 and Figure 7 The third coupling column 51 rotates clockwise, and the upper driving tooth 53 of the third coupling column 51 engages with the upper driven tooth 83 on the transmission rocker 80, driving the transmission rocker 80 to swing along the center of the rotating hole 81. Figure 7 During the swinging process of the transmission rocker 80, the first locking member 42 is driven to rotate by the cooperation between the guide rod 423 and the guide groove 82 until the transmission rod 2121 moves to Figure 9 The leftmost end of the first groove section 1311 (i.e., the intersection of the first groove section 1311 and the second groove section 1312) causes the first locking member 42 to rotate from the position where the cover teeth 421 and the pot teeth 121 are opposite to each other to the position where the cover teeth 421 and the pot teeth 121 are staggered.

[0110] The user continues along Figure 8 The operating knob 2111 is rotated counterclockwise, and the transmission rod 2121 enters the second groove section 1312 and the avoidance section 2212. Since the avoidance section 2212 avoids the trajectory of the transmission rod 2121, the transmission rod 2121 no longer drives the transmission member 22 to move during the rotation process. At this time, the lock column 222 on the transmission member 22 just moves to the top of the lock groove 721, and the free end of the transmission rod 2121 hits the matching inclined surface 63, and the transmission rod 2121 continues to move along the Figure 8 The second locking member 60 rotates in the counterclockwise direction and drives the second locking member 60 to swing along the axis 64 as the center. Figure 11Swing clockwise until the transmission rod 2121 moves to Figure 9 The lower end of the second slot section 1312 causes the second locking member 60 to disengage from the hook portion 415 on the cover assembly 40. At this time, the cover assembly 40 is automatically flipped open under the action of the cover opening torsion spring provided between the pot body assembly 10 and the cover assembly 40.

[0111] Through the above steps, when opening the lid, the pot teeth 121 and the cover teeth 421 between the lid assembly 40 and the pot body assembly 10 are first disengaged, and then the second locking member 60 and the hook portion 415 are disengaged.
