Description

Technical Field

[0001] This utility model relates to the field of small household appliance technology, specifically to a top cover assembly and a cooking utensil. Background Technology

[0002] With the fast pace of modern life, electric pressure cookers have become widely popular due to their quick and convenient cooking method. Electric pressure cookers work by generating pressure higher than atmospheric pressure inside the pot, raising the boiling point of water, thereby shortening cooking time and locking in the nutrients in food.

[0003] In related technologies, the lid of an electric pressure cooker is equipped with a venting assembly, which includes a venting seat and a sealing element. The venting seat has a vent, and the sealing element can open or close the vent.

[0004] However, the short travel distance of the sealing components in the relevant technologies makes them difficult to clean. Utility Model Content

[0005] This invention provides a top cover assembly and a cooking appliance to solve the problems of short travel distance and inconvenient cleaning of sealing components in related technologies.

[0006] According to one aspect of the present invention, a cover assembly is provided, the cover assembly comprising: a cover body having an exhaust chamber; an exhaust assembly including an exhaust seat, a sealing member, a driving member, and a lever, the exhaust seat and the driving member being respectively connected to the cover body, one end of the exhaust seat extending into the exhaust chamber, the portion of the exhaust seat extending into the exhaust chamber having an exhaust port through it, and the driving member being located outside the exhaust chamber; wherein, the middle part of the lever has a hinge portion hinged to the cover body, the first end of the lever abuts against the sealing member, the second end of the lever abuts against the driving end of the driving member, the sealing member being movably disposed in the exhaust chamber, the driving member driving the sealing member to open or close the exhaust port through the lever, and the distance between the first end of the lever and the hinge portion being greater than the distance between the second end of the lever and the hinge portion.

[0007] The cover assembly, utilizing the technical solution of this utility model, includes a cover body and an exhaust assembly. When exhaust is required, a lever is driven to rotate around the hinge by a driving member. Since the first end of the lever abuts against the sealing member, and the second end of the lever abuts against the driving end of the driving member, the rotation of the lever can drive the sealing member to move, thereby opening the exhaust port. When the exhaust port needs to be closed, the lever is driven to rotate in the opposite direction around the hinge by the driving member. Furthermore, since the distance between the first end of the lever and the hinge is greater than the distance between the second end of the lever and the hinge, the travel of the sealing member can be increased without changing the stroke of the driving member. When the sealing member is in the closed exhaust port state, the length of the sealing member extending out of the exhaust chamber can be increased, facilitating cleaning of the sealing member.

[0008] Furthermore, a protrusion is provided in the middle of the lever, and the hinge is disposed on the protrusion; and / or, the swing axis of the lever extends vertically. By providing a protrusion in the middle of the lever, it is convenient to use the protrusion to provide space for the hinge, so that the lever can swing about the swing axis.

[0009] Furthermore, the hinge portion is a hinge hole provided on the protrusion, and the cover body is provided with a hinge post, which is hingedly connected to the hinge hole. This structure achieves a hinged connection between the lever and the cover body, offering advantages such as simple connection structure and ease of assembly.

[0010] Furthermore, the driving component is an electric actuator, which includes a base and a rod movably mounted on the base. A mounting seat with a mounting groove is provided on the cover body. The base is disposed within the mounting groove, and the rod extends out of the mounting groove. The lever is located on the side of the mounting seat closer to the sealing element. By extending or retracting the rod relative to the base, the lever can be driven to rotate relative to the cover body. The mounting groove of the mounting seat provides assembly space for the base. Because the lever is located on the side of the mounting seat closer to the sealing element, the arrangement of the components is more compact.

[0011] Furthermore, the sealing component includes a connecting rod and a push rod. The connecting rod is movably inserted through the exhaust port, and the push rod is movably inserted through the side wall of the exhaust chamber. One end of the push rod abuts against the connecting rod, and the other end of the push rod abuts against the first end of the lever. When exhaust is required using the exhaust assembly, the lever is driven to rotate around the hinge by a driving component. Since one end of the push rod abuts against the connecting rod, and the other end of the push rod abuts against the first end of the lever, the lever can drive the push rod to move when it rotates. The push rod drives the connecting rod to move, thereby opening the exhaust port using the connecting rod.

[0012] Furthermore, a first sealing ring is provided on the side wall of the exhaust chamber, and the push rod is movably inserted through the first sealing ring. The gas in the exhaust chamber will not be discharged from the position where the push rod is inserted, that is, the gas in the exhaust chamber will only be discharged through a preset path, which can improve the sealing effect and exhaust effect of the device.

[0013] Furthermore, the portion of the exhaust seat extending into the exhaust chamber is provided with two exhaust ports, and a sealing member passes through the two exhaust ports. The sealing member has two second sealing rings corresponding to the two exhaust ports, which can open or close the corresponding exhaust ports. By providing two exhaust ports, the exhaust speed can be increased. And / or, the exhaust assembly also includes a reset member, which is disposed between the sealing member and the exhaust seat. The reset member can reset the sealing member from the exhaust port open state to the closed state. After the drive member releases the lever, under the reset force of the reset member, the sealing member will reset from the exhaust port open state to the closed state, at which point the sealing member drives the lever to rotate in the opposite direction around the hinge.

[0014] Furthermore, the lid body includes an outer lid and a pressure-bearing lid located below the outer lid. The venting chamber is disposed on the outer lid, the venting seat is connected to the pressure-bearing lid, and the driving component and lever are respectively connected to the outer lid. The pressure-bearing lid can withstand the pressure of the cooking chamber, and the outer lid can shield the pressure-bearing lid and other components, improving the integrity of the upper lid assembly.

[0015] Furthermore, the outer cover includes a steam seat, and an exhaust chamber is disposed within the steam seat, which is connected to the pressure cover. The steam seat facilitates the machining of the exhaust chamber. Since the steam seat is connected to the pressure cover, it rotates together with the pressure cover; that is, the exhaust seat, the sealing component, and the steam seat all rotate together with the pressure cover.

[0016] According to another aspect of this utility model, a cooking appliance is provided, comprising: a pot body; and a lid assembly that is detachably and closably disposed on the pot body, the lid assembly being the aforementioned lid assembly. Therefore, this cooking appliance can also increase the travel distance of the sealing member, and when the sealing member is in the closed vent state, the length of the sealing member extending out of the vent cavity can be increased, facilitating cleaning of the sealing member.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0031] like Figures 1 to 9As shown, this embodiment of the present invention provides a lid assembly, which includes a lid body 10 and an exhaust assembly 20. The lid body 10 has an exhaust chamber 11, and the exhaust assembly 20 includes an exhaust seat 21, a sealing member 22, a driving member 23, and a lever 24. The exhaust seat 21 and the driving member 23 are respectively connected to the lid body 10. One end of the exhaust seat 21 extends into the exhaust chamber 11, and the portion of the exhaust seat 21 extending into the exhaust chamber 11 is provided with an exhaust port 211. The driving member 23 is located outside the exhaust chamber 11. Gas inside the pot of the cooking appliance can be discharged into the exhaust chamber 11 through the exhaust port 211 of the exhaust seat 21. The lever 24 has a hinge portion 241 in the middle that is hinged to the cover body 10. The first end of the lever 24 abuts against the sealing member 22, and the second end of the lever 24 abuts against the driving end of the driving member 23. The sealing member 22 is movably inserted into the exhaust chamber 11. The driving member 23 drives the sealing member 22 to open or close the exhaust port 211 through the lever 24. The distance between the first end of the lever 24 and the hinge portion 241 is greater than the distance between the second end of the lever 24 and the hinge portion 241.

[0032] Using the top cover assembly provided in this embodiment, when venting is required using the venting assembly 20, the driving member 23 drives the lever 24 to rotate around the hinge portion 241. Since the first end of the lever 24 abuts against the sealing member 22 and the second end of the lever 24 abuts against the driving end of the driving member 23, the lever 24 can drive the sealing member 22 to move when rotating, so that the sealing member 22 opens the vent 211. When it is necessary to close the vent 211, the driving member 23 drives the lever 24 to rotate in the opposite direction around the hinge portion 241. Furthermore, since the distance between the first end of the lever 24 and the hinge portion 241 is greater than the distance between the second end of the lever 24 and the hinge portion 241, the travel of the sealing member 22 can be increased without changing the stroke of the driving member 23. When the sealing member 22 is in the state of closing the vent 211, the length of the sealing member 22 extending out of the vent chamber 11 can be increased, making it easier to clean the sealing member 22.

[0033] In this embodiment, the swing axis of lever 24 extends vertically. When lever 24 swings about the vertical swing axis, both ends of lever 24 swing horizontally.

[0034] like Figure 1 As shown, the cover body 10 includes an outer cover 15 and a pressure-bearing cover 16 located below the outer cover 15. An exhaust chamber 11 is disposed on the outer cover 15, and an exhaust seat 21 is connected to the pressure-bearing cover 16. A drive member 23 and a lever 24 are respectively connected to the outer cover 15. The pressure-bearing cover 16 can withstand the pressure of the cooking chamber, and the outer cover 15 can shield the pressure-bearing cover 16 and other components, improving the integrity of the upper cover assembly.

[0035] like Figure 1 and Figure 2 As shown, the outer cover 15 includes a steam seat 17, and an exhaust chamber 11 is disposed on the steam seat 17 to facilitate the processing of the exhaust chamber 11. The steam seat 17 is connected to the pressure cover 16, and the steam seat 17 rotates together with the pressure cover 16. That is, the exhaust seat 21, the sealing member 22, and the steam seat 17 all rotate together with the pressure cover 16, while the driving member 23 and the lever 24 remain stationary relative to the pressure cover 16.

[0036] Specifically, the exhaust seat 21 passes through the steam seat 17 and the pressure cover 16, and the exhaust seat 21 presses the steam seat 17 onto the pressure cover 16 to fix the steam seat 17.

[0037] It should be noted that, since the pressure cover 16 is a rotating mechanism, the sealing component 22, which rotates along with the pressure cover 16, will have an alignment issue relative to the driving component 23, which is stationary on the outer cover 15. In other words, it depends on whether the driving component 23 can be aligned with the sealing component 22, for example, whether the axis of the driving component 23 coincides with the axis of the sealing component 22, and whether there is an angle between them. If there is an angle between the axes of motion of the two components, there will be a component force, affecting the smoothness of movement of the moving component (sealing component 22).

[0038] In this embodiment, the influence of this angle can be reduced by using lever 24 for transmission, because the abutting end of lever 24 is oscillating. Specifically, when rotating the pressure cover 16, the sealing member 22 and the driving member 23 may have different angles, and during the process of the abutting end of lever 24 abutting and pushing against the sealing member 22, the pushing force of lever 24 on the sealing member 22 can be kept as consistent as possible with the moving direction of the sealing member 22, ensuring smooth operation.

[0039] Furthermore, since the lever 24 can increase the travel of the sealing member 22, the size of the sealing member 22 can reduce the impact on the volume of the exhaust chamber 11 by increasing the travel, thereby increasing the volume of the exhaust chamber 11 and facilitating manual cleaning of the exhaust chamber 11.

[0040] In summary, by setting lever 24, the driving force of the drive mechanism on the sealing component 22 can be kept as consistent as possible with the moving direction of the sealing component 22, ensuring the smooth operation of the sealing component 22; in addition, lever 24 can also increase the volume of the exhaust chamber 11, which is conducive to manual cleaning of the exhaust chamber 11.

[0041] It should be noted that when it is necessary to close the exhaust port 211, the lever 24 can be driven to rotate in the opposite direction around the hinge 241 by the driving member 23. The rotation of the lever 24 around the hinge 241 in the opposite direction can be achieved in two ways: the first is to directly drive the lever 24 around the hinge 241 in the opposite direction by the driving member 23, and the second is to indirectly drive the lever 24 around the hinge 241 in the opposite direction by the reset member.

[0042] The middle part of lever 24 refers to the part of lever 24 excluding its two ends.

[0043] In this embodiment, the exhaust assembly 20 further includes a reset member 25, which is disposed between the sealing member 22 and the exhaust seat 21. The reset member 25 enables the sealing member 22 to reset from the exhaust state with the exhaust port 211 open to the closed state with the exhaust port 211 closed. After the driving member 23 releases the lever 24, under the action of the reset force of the reset member 25, the sealing member 22 will reset from the exhaust state with the exhaust port 211 open to the closed state with the exhaust port 211 closed. At this time, the sealing member 22 drives the lever 24 to rotate in the opposite direction around the hinge portion 241.

[0044] like Figure 8 As shown, a protrusion 242 is provided in the middle of the lever 24, and a hinge portion 241 is provided on the protrusion 242. By providing a protrusion 242 in the middle of the lever 24, it is convenient to use the protrusion 242 to provide space for the hinge portion 241.

[0045] In this embodiment, the hinge portion 241 is a hinge hole 2411 provided on the protrusion 242, and the cover body 10 is provided with a hinge post 12, which is hingedly connected to the hinge hole 2411. The above structure realizes the hinged connection between the lever 24 and the cover body 10, which has the advantages of simple connection structure and easy assembly.

[0046] like Figures 3 to 6 as well as Figure 9 As shown, the driving component 23 is an electric push rod 231. The electric push rod 231 includes a base 2311 and a rod 2312 movably disposed on the base 2311. The cover body 10 is provided with a mounting seat 13. The mounting seat 13 has a mounting groove 131. The base 2311 is disposed in the mounting groove 131. The rod 2312 can extend out of the mounting groove 131. The lever 24 is located on the side of the mounting seat 13 near the sealing component 22.

[0047] By extending or retracting the rod 2312 relative to the seat 2311, the lever 24 can be driven to rotate relative to the cover body 10. The mounting groove 131 of the mounting base 13 provides assembly space for the seat 2311. Because the lever 24 is located on the side of the mounting base 13 closer to the sealing member 22, the arrangement of the components is more compact.

[0048] like Figure 2 As shown, the sealing component 22 includes a connecting rod 221 and a push rod 222. The connecting rod 221 is movably inserted through the exhaust port 211, and the push rod 222 is movably inserted through the side wall of the exhaust chamber 11. One end of the push rod 222 abuts against the connecting rod 221, and the other end of the push rod 222 abuts against the first end of the lever 24.

[0049] When exhaust assembly 20 is needed, the drive member 23 drives lever 24 to rotate around hinge 241. Since one end of push rod 222 abuts against connecting rod 221 and the other end of push rod 222 abuts against the first end of lever 24, lever 24 can drive push rod 222 to move when it rotates. Push rod 222 drives connecting rod 221 to move, thereby opening exhaust port 211 using connecting rod 221.

[0050] like Figure 2 As shown, a first sealing ring 14 is provided on the side wall of the exhaust chamber 11, and the push rod 222 is movably inserted through the first sealing ring 14. The gas in the exhaust chamber 11 will not be discharged from the position through which the push rod 222 is inserted, that is, the gas in the exhaust chamber 11 will only be discharged through a preset path, which can improve the sealing effect and exhaust effect of the device.

[0051] like Figure 2 As shown, the portion of the exhaust seat 21 extending into the exhaust chamber 11 has two exhaust ports 211. A sealing member 22 passes through the two exhaust ports 211, and the sealing member 22 has two second sealing rings 223 respectively corresponding to the two exhaust ports 211. The second sealing rings 223 can open or close the corresponding exhaust ports 211. By providing two exhaust ports 211, the exhaust speed can be increased.

[0052] Furthermore, one of the second sealing rings 223 is located on the outside of the exhaust seat 21, and the other second sealing ring 223 is located on the inside of the exhaust seat 21. When the exhaust port 211 is opened using the sealing member 22, the gas pressure at the two second sealing rings 223 will cancel each other out, which facilitates the movement of the sealing member 22 and allows the exhaust port 211 to open smoothly.

[0053] Another embodiment of this utility model provides a cooking appliance, which includes a pot body and a lid assembly. The lid assembly is detachably mounted on the pot body and is the same as the lid assembly described above. Therefore, this cooking appliance can also increase the travel of the sealing member 22. When the sealing member 22 is in the state of closing the vent 211, the length of the sealing member 22 extending out of the vent 11 can be increased, making it easier to clean the sealing member 22.

[0054] Cooking appliances include, but are not limited to, electric pressure cookers and multi-functional cookers with pressure cooking functions.
