Description

Technical Field

[0001] This invention relates to the field of cooking utensil technology, and more specifically, to a lid assembly and a cooking utensil having the same. Background Technology

[0002] Currently, electric pressure cookers have an exhaust channel on their lids for venting. The exhaust channel contains an exhaust assembly, which typically includes a drive component, a connecting rod, and a reset component. One of the drive component and the reset component drives the connecting rod to open the exhaust channel, while the other drives the connecting rod to close the exhaust channel, thus enabling the electric pressure cooker lid to vent.

[0003] In existing technology, during the venting process of an electric pressure cooker, some soup or other solids may splash out and land on the components around the venting assembly. Over time, this can lead to mold growth, necessitating regular cleaning of the components around the venting assembly. However, the presence of the venting assembly hinders users from cleaning these components. Therefore, when cleaning the components around the venting assembly, users often need to remove the elastic element within the venting assembly. After cleaning and reinstalling the reset element, users cannot determine if the elastic element is properly installed. They can only determine its proper installation by observing the venting effect or hearing unusual noises during venting, causing inconvenience. Furthermore, an improperly installed venting assembly can affect the venting process. Summary of the Invention

[0004] The present invention provides a cover assembly and a cooking appliance having the same, to solve the problem in the prior art that it is impossible to determine whether the reset component is installed in place.

[0005] According to one aspect of the present invention, a cover assembly is provided, the cover assembly comprising: a cover having an exhaust channel having an air inlet and a first air outlet communicating with the outside; a connecting rod movably disposed on the cover having a sealing position for sealing the first air outlet and an opening position for opening the first air outlet; and an alignment assembly comprising: an alignment member detachably mounted on the cover; a movable member slidably mounted on the alignment member; and an elastic member connected between the alignment member and the movable member; wherein, when the alignment member is assembled on the cover, the movable member is at least partially located between the elastic member and the connecting rod, such that the elastic member can push the connecting rod to move via the movable member.

[0006] By applying the technical solution of this invention, the alignment component and the movable component are detachably installed on the cover, and the elastic component is placed between the alignment component and the movable component. In this way, the alignment component, the elastic component, and the movable component can be disassembled as a whole. When the alignment component is installed in place, the movable component is at least partially located between the elastic component and the connecting rod. This ensures that the elastic component drives the connecting rod to move through the movable component, so that when the alignment component is installed in place, the elastic component can also be installed in place. This facilitates the user's disassembly and assembly of the alignment component, the movable component, and the elastic component, enabling rapid and accurate installation of product components, improving installation efficiency, and ensuring that the elastic component can be used normally after installation.

[0007] Furthermore, during the assembly of the alignment component onto the cover, the movable component drives the connecting rod to move via the first drive structure, ensuring that the central axis of the connecting rod is parallel to the central axis of the first air outlet. Thus, when the alignment component is in place, the connecting rod is also aligned with the first outlet, facilitating subsequent switching between the sealed and open positions and improving the accuracy of the drive.

[0008] Furthermore, a first drive structure is disposed on the movable component. The first drive structure includes: a first guide surface having a first side and a second side disposed opposite to each other in a vertical direction, the first guide surface gradually approaching the exhaust channel from the first side to the second side; and / or, a second guide surface extending circumferentially along the alignment component, the second guide surface having a first end and a second end disposed opposite to each other in an extending direction, the second guide surface gradually approaching the exhaust channel from the first end to the second end; wherein, when the first drive structure includes a first guide surface and a second guide surface, the first guide surface and the second guide surface are distributed in a vertical direction, and the first guide surface is located below the second guide surface. In this way, the connecting rod moves to the sealing position through the first drive structure, realizing automatic alignment of the connecting rod and the movable component, avoiding assembly errors caused by the inability to observe whether the connecting rod and the movable component are properly assembled, improving the assembly efficiency of the connecting rod and the movable component, and simultaneously improving the assembly accuracy of the alignment component.

[0009] Furthermore, the alignment component can rotate circumferentially relative to the exhaust channel, and there is a snap-fit ​​structure between the alignment component and the cover, which is used to fix the alignment component. Compared with fasteners and other connection structures, the snap-fit ​​structure is simple and can realize quick assembly and disassembly of the alignment component and the cover.

[0010] Furthermore, the exhaust channel extends vertically, and the connecting rod passes through the first exhaust port in a direction perpendicular to the exhaust channel. This ensures that the exhaust path formed at the first exhaust port is radial, which is different from the airflow direction within the exhaust channel. This avoids the difficulty in position switching caused by fluid flow affecting the connecting rod if its extension direction is aligned with that of the exhaust channel, thus guaranteeing the efficiency of connecting rod position switching.

[0011] Furthermore, a first seal is provided on the connecting rod, which is used to seal the first vent. The first seal increases the contact area between the connecting rod and the first vent, preventing fluid from escaping from the first vent when the connecting rod is in the sealed position, thus ensuring the sealing effect at the first vent when the connecting rod is in the sealed position.

[0012] Furthermore, a second guide structure is provided between the positioning component and the moving component to guide the movement of the moving component. This ensures the accuracy of the linkage's movement direction, thereby guaranteeing the sealing effect of the seals on the linkage on the air outlet, and also improving the speed at which the linkage switches between different states.

[0013] Furthermore, the second guiding structure includes a guide groove and a guide protrusion. The alignment member has a guide groove that extends along the moving direction of the movable member. The movable member has a guide protrusion that is movably disposed within the guide groove. The guide groove and the guide protrusion cooperate to form the second guiding structure. This design is simple and easy to manufacture. Moreover, the cooperation between the guide groove and the guide protrusion provides a self-locking anti-rotation function, preventing relative swaying between the movable member and the alignment member during movement.

[0014] Furthermore, the second guide structure also includes baffles and a limiting block. Two baffles are provided at one end of the movable member along the moving direction, spaced apart from each other and extending along the moving direction of the movable member. The limiting block is disposed on the aligning member and is located between the two baffles. The limiting block cooperates with the two baffles to restrict the rotation of the movable member relative to the aligning member. This structure, in conjunction with the guide groove and guide protrusion, ensures the stability of the movable member's movement, thereby improving the accuracy of the connecting rod switching between the sealed and open positions.

[0015] Furthermore, the fastening structure includes: a fastening rail, circumferentially disposed on the inner wall of the cover, one end of the fastening rail having a relief groove communicating with the fastening rail; and a protrusion, disposed on the outer wall of the alignment component, the protrusion entering the fastening rail through the relief groove, and the protrusion being movable along the fastening rail. Through the above arrangement, the fastening rail and the protrusion can guide and limit the rotation direction of the alignment component, ensuring that the alignment component can be smoothly assembled with the cover.

[0016] Furthermore, a sealing structure is provided between the outer periphery of the aligning member and the cover body to seal the gap between the aligning member and the cover body. This ensures the airtightness of the inside of the cover body and prevents fluid inside the cover body from leaking into the external components of the cover body and causing damage.

[0017] According to another aspect of the present invention, a cooking appliance is provided, comprising the lid assembly of the aforementioned claim. The lid assembly effectively solves the problem of poor installation accuracy of the alignment components and connecting rods on the lid assembly in the prior art. Automatic alignment of the connecting rods is achieved through a first driving structure, improving assembly efficiency. The cooking appliance having the lid assembly also possesses the aforementioned advantages. Attached Figure Description

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] like Figures 1 to 9As shown, this embodiment of the invention provides a cover assembly, which includes a cover 10, a connecting rod 20, and an alignment component 30. The cover 10 has an exhaust channel 12. The exhaust channel 12 has an air inlet 121 and a first air outlet 122, which are oppositely disposed and communicate with the outside. The connecting rod 20 is movably disposed within the cover 10 and has a sealing position for sealing the first air outlet 122 and an opening position for opening the first air outlet 122. The alignment component 30 is detachably connected to the cover 10 and is located within the cover 10. The alignment component 30 has an installation position and a disassembly position oppositely disposed. The alignment component 30 includes an alignment member 31, a movable member 32, and an elastic member 33. The alignment member 31 is detachably mounted on the cover 10. The movable member 32 is slidably mounted on the alignment member 31; the elastic member 33 is connected between the alignment member 31 and the movable member 32. When the alignment member 31 is assembled on the cover 10, the movable member 32 is at least partially located between the elastic member 33 and the connecting rod 20, so that the elastic member 33 can push the connecting rod 20 to move through the movable member 32.

[0050] By applying the technical solution of this invention, the alignment member 31 and the movable member 32 are detachably installed on the cover 10, and the elastic member 33 is disposed between the alignment member 31 and the movable member 32. In this way, the alignment member 31, the elastic member 33 and the movable member 32 can be disassembled as a whole. When the alignment member 31 is installed in place, the movable member 32 is at least partially located between the elastic member 33 and the connecting rod 20. This ensures that the elastic member 33 drives the connecting rod 20 to move through the movable member 32, so that when the alignment member 31 is installed in place, the elastic member 33 can also be installed in place. This makes it convenient for users to disassemble and assemble the alignment member 31, the movable member 32 and the elastic member 33, realize the rapid and accurate installation of product components, improve installation efficiency, and ensure that the elastic member 33 can be used normally after installation.

[0051] Compared to the prior art where the movable part 32 is separately located in the cover 10, the above-described configuration integrates the movable part 32 onto the alignment component 30. This not only facilitates the assembly and disassembly of the movable part 32 but also eliminates the need for additional structures within the cover 10 to fix the movable part 32, reducing the number of components within the cover 10 and facilitating the cleaning of impurities. It also allows for easy adjustment of the alignment component 31's assembly position. The alignment component 31 can cover the connecting rod 20, thereby enhancing the customer experience. The movable part 32 is movably positioned on the side of the alignment component 31 facing the connecting rod 20 and has a first driving structure 321. This configuration ensures the stability of the alignment component 31 after assembly when the first driving structure 321 drives the connecting rod 20 to move. Thus, the alignment component 30 can both cover the connecting rod 20 and drive it to a sealing position, ensuring that the connecting rod 20 can subsequently seal or open the first vent 122, improving the functionality and practicality of the alignment component 30.

[0052] Furthermore, the elastic element 33 can provide the movable element 32 with an elastic force to drive the connecting rod 20 to the sealing position. By providing the driving force to the movable element 32 through the elastic element 33, the connecting rod 20 is switched from the open position to the sealed position. This structure is simple and compact, reducing manufacturing costs, facilitating disassembly and assembly, and not occupying too much space, making the cover lighter. At the same time, the elastic element 33 can also provide a preload force to the movable element 32 to improve the assembly stability of the movable element 32.

[0053] In this application, the specific structure of the elastic element 33 is not limited, as long as it can provide the driving force for the connecting rod 20 to switch from the open position to the sealed position. In this embodiment, the elastic element 33 is a spring. The elastic element 33 can be directly fixed to the alignment member 31, or a stop member can be provided on the alignment member 31, with one end of the elastic element 33 placed on the stop member.

[0054] During the assembly of the alignment component 31 onto the cover 10, the movable component 32 drives the connecting rod 20 to move via the first drive structure 321, so that the central axis of the connecting rod 20 is parallel to the central axis of the first air outlet 122. Thus, when the alignment component 31 is in place, the connecting rod 20 is also aligned with the first air outlet 122, facilitating subsequent switching between the sealed and open positions and improving the accuracy of the drive.

[0055] The cover 10 has a steam chamber 11, which is connected to the exhaust channel 12. The connecting rod 20 and the alignment assembly 30 are located inside the steam chamber 11.

[0056] like Figure 5 and Figure 6As shown, a first drive structure 321 is disposed on the movable member 32. The first drive structure 321 includes a first guide surface 3211 and a second guide surface 3212. The first guide surface 3211 has a first side 32111 and a second side 32112 arranged opposite each other in a vertical direction, and the first guide surface 3211 gradually approaches the exhaust passage 12 from the first side 32111 to the second side 32112. The second guide surface 3212 extends circumferentially along the alignment assembly 30, and has a first end 32121 and a second end 32122 arranged opposite each other in the extending direction, and the second guide surface 3212 gradually approaches the exhaust passage 12 from the first end 32121 to the second end 32122. The first guide surface 3211 and the second guide surface 3212 are distributed in a vertical direction, and the first guide surface 3211 is located below the second guide surface 3212.

[0057] like Figures 1 to 3 As shown, the cover 10 also includes a steam seat 13, a steam cover 14, and an exhaust seat 50. The steam seat 13 and the steam cover 14 cooperate to form the cover 10. The exhaust seat 50 is vertically mounted on the steam seat 13. The alignment member 31 is located above the exhaust seat 50. The exhaust seat 50 is located on the cover 10. The exhaust seat 50 has an exhaust channel 12. The connecting rod 20 is mounted on the exhaust seat 50. The bottom of the exhaust seat 50 has an air inlet 121, and the top of the exhaust seat 50 has a first air outlet 122.

[0058] When assembling the alignment component 30 and the steam seat 13, the alignment component 30 and the connecting rod 20 need to be properly aligned. Through the above design, one end of the connecting rod 20 first contacts the first side 32111 of the first guide surface 3211. As the alignment component 30 moves downwards towards the steam seat 13, one end of the connecting rod 20 moves through the first guide surface 3211 to the second guide surface 3212. At this point, the alignment component 30 and the steam seat 13 are axially aligned. The second guide surface 3212 moves with the alignment component 30, abutting against one end of the connecting rod 20 and moving relative to it. Then, the second guide surface 3212 drives the alignment component 30 to adjust to the installation position. This achieves automatic alignment of the connecting rod 20 and the alignment component 30, avoiding assembly errors caused by the inability to observe whether the connecting rod 20 and the alignment component 30 are properly aligned, improving the assembly efficiency of the connecting rod 20 and the alignment component 30, and simultaneously improving the assembly accuracy of the alignment component 30. The first guide surface 3211 and the second guide surface 3212 have a transition arc surface so that the connecting rod 20 can smoothly transition from the first guide surface 3211 to the second guide surface 3212.

[0059] In other embodiments of this application, the first drive structure 321 may include only the first guide surface 3211, or the first drive structure 321 may include only the second guide surface 3212.

[0060] like Figure 1 As shown, the alignment component 30 can rotate circumferentially relative to the exhaust channel 12. A fastening structure exists between the alignment component 30 and the cover 10 to secure the alignment component 30. Compared to fasteners and other connection structures, the fastening structure is simple and allows for quick assembly and disassembly of the alignment component 30 and the cover 10. Simultaneously, the fastening structure provides a good locking effect, ensuring the stability of the alignment component 30 and the cover 10 after assembly and reducing the possibility of loosening or displacement during use.

[0061] This application does not limit the specific form of the fastening structure. The fastening structure can be magnetic fastening, elastic fastening, or wedge connection, etc.

[0062] like Figures 1 to 3 As shown, the exhaust channel 12 extends vertically, and the connecting rod 20 is inserted at the first air outlet 122 in the direction perpendicular to the exhaust channel 12. This makes the exhaust path formed at the first air outlet 122 radial, which is different from the airflow direction in the exhaust channel 12. This can avoid the difficulty of position switching caused by the fluid flow if the connecting rod 20 is aligned with the extension direction of the exhaust channel 12, and ensure the position switching efficiency of the connecting rod 20.

[0063] like Figure 2 and Figure 9 As shown, the alignment member 31 has an exhaust port 310 so that fluid flows into the cover 10 from the exhaust channel 12. Specifically, there is no limitation on the number and location of the exhaust ports 310. The exhaust ports 310 can be one or more, and the exhaust ports 310 can be located on the side wall of the alignment member 31 or on the top of the alignment member 31.

[0064] In this design, the specific structure and movement of the movable component 32 are not limited, as long as it can drive the connecting rod 20. The movable component 32 is configured as a ring structure, which is sleeved on the outside of the exhaust seat 50, and the connecting rod 20 is located inside the ring structure. Configuring the movable component 32 as a ring structure simplifies its structure, provides a large contact area with the positioning component 31, and makes its movement more stable relative to the positioning component 31.

[0065] Specifically, a guide rail can be provided on the alignment member 31, and a snap-fit ​​engagement can be provided on the movable member 32. Alternatively, a snap-fit ​​engagement can be provided on the alignment member 31, and a guide rail engagement can be provided on the movable member 32. The movable member 32 can be moved by power provided by a lead screw or a motor.

[0066] The connecting rod 20 is equipped with a first seal 21, which seals the first vent 122. The first seal 21 increases the contact area between the connecting rod 20 and the first vent 122, preventing fluid from escaping from the first vent 122 when the connecting rod 20 is in the sealed position, thus ensuring a proper seal at the first vent 122. The first seal 21 is located outside the exhaust channel 12. The specific structure of the first seal 21 is not limited; it can be a sealing ring, a sealing gasket, or a sealing strip.

[0067] In this design, the exhaust seat 50 also has a second air outlet 123, and the connecting rod 20 is also provided with a second seal 22. The first seal 21 and the second seal 22 are spaced apart on the connecting rod 20, and the second seal 22 is positioned corresponding to the second air outlet 123 to seal the second air outlet 123. The connecting rod 20 passes through the first air outlet 122 and the second air outlet 123. When the connecting rod 20 is in the sealed position, it can simultaneously seal the first air outlet 122 and the second air outlet. Thus, the gas flowing in from the air inlet 121 can be simultaneously discharged from the first air outlet 122 and the second air outlet 123, increasing the number of fluid flow channels, thereby increasing the cross-sectional area of ​​the exhaust channel 12, improving the fluid flow rate, and increasing the single discharge volume of the fluid. The first seal 21 is located inside the exhaust channel 12.

[0068] like Figure 1 and Figure 4 As shown, specifically, the connecting rod 20 is also provided with a first groove 201 and a second groove 202. The first groove 201 is used to fix the first seal 21, and the second groove 202 is used to fix the second seal 22, so as to prevent the first seal 21 and the second seal 22 from loosening during the movement of the connecting rod 20 and to ensure the sealing effect of the seals on the air outlet.

[0069] like Figure 1 As shown, the cover 10 also includes a drive mechanism 15, which is drivenly connected to the movable part 32. The drive mechanism 15 can drive the movable part 32 to move relative to the positioning part 31. In this embodiment, the drive mechanism is a solenoid valve, which can realize the switching of the connecting rod 20 from the sealed position to the open position. The elastic part 33 cooperates with the solenoid valve to realize the switching of the connecting rod 20 between the open position and the sealed position.

[0070] In other embodiments of this application, the drive mechanism 15 can be configured as a telescopic component, such as a hydraulic cylinder, electric cylinder, or lead screw, which can drive the connecting rod 20 to reciprocate, thus eliminating the need for the elastic component 33.

[0071] like Figure 7As shown, a second guide structure 34 is provided between the alignment member 31 and the movable member 32. The second guide structure 34 is used to guide the movement of the movable member 32. With the above arrangement, the movable member 32 can be prevented from shifting relative to the alignment member 31, thereby avoiding interference or influence on the movement of the connecting rod 20. This ensures the accuracy of the movement direction of the connecting rod 20, thus ensuring the sealing effect of the seal on the connecting rod 20 on the air outlet, and also improving the speed at which the connecting rod 20 switches between different states.

[0072] In this solution, the specific form of the second guide structure 34 is not limited. In some embodiments of this application, the second guide structure 34 may include guide posts, guide ribs, etc. In other embodiments of this application, the second guide structure 34 may also be configured as a guide rail cooperating with a protrusion for guidance.

[0073] Specifically, the second guide structure 34 includes a guide groove 341 and a guide protrusion 342. The alignment member 31 has a guide groove 341 that extends along the moving direction of the movable member 32. The movable member 32 has a guide protrusion 342, which is movably disposed within the guide groove 341. The guide groove 341 and the guide protrusion 342 cooperate to form the second guide structure 34. The above design is simple and easy to manufacture. Furthermore, the cooperation between the guide groove 341 and the guide protrusion 342 also has an anti-rotation function, which can prevent relative swaying between the movable member 32 and the alignment member 31 during movement.

[0074] In this embodiment, the guide groove 341 includes a side wall and a bottom wall. The alignment member 31 has two guide grooves 341 arranged opposite to each other. The two guide grooves 341 cooperate with each other to form a mounting cavity. The movable member 32 is movably located in the mounting cavity. The bottom wall of the guide groove 341 can support the movable member 32, and the side wall of the guide groove 341 can limit the movable member 32 to prevent the movable member 32 from deflecting when moving.

[0075] like Figure 6 and Figure 7As shown, the second guide structure 34 also includes baffles 343 and limiting blocks 344. Two baffles 343 are provided at one end of the movable member 32 along the moving direction, spaced apart from each other. The baffles 343 extend along the moving direction of the movable member 32. The limiting block 344 is disposed on the aligning member 31 and is located between the two baffles 343. The limiting block 344 cooperates with the two baffles 343 to restrict the rotation of the movable member 32 relative to the aligning member 31. This structure can cooperate with the guide groove 341 and the guide protrusion 342 to further prevent the movable member 32 from rotating or swaying relative to the aligning member 31 under external force, ensuring the stability of the movable member 32's movement and thus improving the accuracy of the connecting rod 20 switching between the sealed and open positions. Furthermore, the above structure is simple, easy to manufacture, and does not occupy excessive space.

[0076] In other embodiments of this application, the two retaining ribs 343 may also be located within the limiting block 344.

[0077] like Figure 7 and Figure 8 As shown, the fastening structure includes a fastening rail 41 and a protrusion 42. The fastening rail 41 is circumferentially disposed on the inner wall of the cover 10, and one end of the fastening rail 41 has a relief groove 411 communicating with the fastening rail 41. The protrusion 42 is disposed on the outer wall of the alignment component 30, and the protrusion 42 enters the fastening rail 41 through the relief groove 411, and the protrusion 42 can move along the fastening rail 41. Through the above arrangement, the alignment component 30 can rotate within the cover 10 via the protrusion 42 to adjust the assembly position of the alignment component 30 and the cover 10. The fastening rail 41 and the protrusion 42 can also guide and limit the rotation direction of the alignment component 30, ensuring that the alignment component 30 can be smoothly assembled with the cover 10.

[0078] In this embodiment, the fastening rail 41 is disposed on the steam seat 13. In this application, multiple fastening rails 41 are disposed, and the number is not limited. In this embodiment, three fastening rails 41 are disposed. In other embodiments, two, three, or five fastening rails 41 may also be disposed.

[0079] The aligning member 31 has a sealing structure between its outer periphery and the cover 10. This sealing structure is used to seal the gap between the aligning member 31 and the cover 10. This ensures the airtightness of the cover 10 and prevents fluid inside the cover 10 from leaking into the external components of the cover 10 and causing damage.

[0080] In this design, the form of the sealing structure is not limited. Multiple sealing grooves can be machined circumferentially on the contact surface between the alignment member 31 and the steam seat 13, and sealing rings can be placed in the sealing grooves. Alternatively, multiple sealing grooves can be circumferentially arranged on the contact surface between the steam cover 14 and the alignment member 31, and sealing rings can be placed in the sealing grooves.

[0081] like Figure 1 and Figure 9 As shown, in this embodiment, the alignment member 31 is provided with an upper fixing groove 301 and a lower fixing groove 302 in sequence along the circumferential direction in the axial direction. The upper fixing groove 301 and the lower fixing groove 302 are arranged in a ring around the outer periphery of the alignment member 31. A sealing ring is provided in both the upper fixing groove 301 and the lower fixing groove 302. The upper fixing groove 301 abuts against the steam cover 14, and the lower fixing groove 302 abuts against the steam seat 13.

[0082] Specifically, the assembly process of the alignment component 30 and the cover 10 is as follows: First, the alignment component 31 is placed on the steam seat 13. At this time, the protrusion 42 on the alignment component 30 is inserted into the clearance groove 411 on the steam seat 13. Then, the alignment component 31 is rotated, and the protrusion 42 rotates a certain angle on the fastening rail 41 on the steam seat 13 and then enters its position. At the same time, when the alignment component 30 is placed on the steam seat 13, the connecting rod 20 will contact the first drive structure 321 on the movable component 32. When the alignment component 30 moves axially, the first guide surface 3211 will push the connecting rod 20 to the second guide surface 3212. Subsequently, when the alignment component 30 rotates, the second guide surface 3212 will drive the connecting rod 20 to slide to the sealing position. When the alignment component 30 is rotated into place, the connecting rod 20 is just in the sealing position. When the alignment component 30 needs to be disassembled, the protrusion 42 on the alignment component 30 is screwed into the relief groove 411 on the steam seat 13, and then the alignment component 30 can be removed.
