Description

Technical Field

[0001] The utility model relates to the technical field of small household appliances, and particularly to a cover assembly and a cooking appliance having the same. Background Art

[0002] In the related art, the pressure limiting valve of the pressure cooking appliance is arranged eccentrically from the center of the cover assembly, so as to avoid the center of the top of the cover assembly, so that an area near the user and the middle area of the cover assembly can be used to arrange the operation panel, thus facilitating the use of the user.

[0003] However, since the pressure limiting valve needs to rotate relative to the upper cover together with the inner cover, the steam seat for installing the pressure limiting valve will also rotate relative to the upper cover. In order to ensure the smooth rotation of the inner cover, the steam seat and the pressure limiting valve, there is generally a gap between the steam seat and the upper cover, and water vapor is likely to enter between the upper cover and the inner cover through the gap between the two. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a cover assembly and a cooking appliance having the same, so as to solve the problem that water vapor easily enters between the upper cover and the inner cover due to the eccentric setting of the pressure limiting valve in the related art.

[0005] To achieve the above object, according to one aspect of the utility model, a cover assembly is provided, including: an upper cover having an exhaust port; an inner cover rotatably arranged below the upper cover, the inner cover including a cover body and an exhaust structure arranged on the cover body; a sealing turntable arranged between the upper cover and the inner cover and capable of rotating synchronously with the inner cover, the exhaust structure passing through the sealing turntable, and the sealing turntable being in sealing cooperation with both the upper cover and the exhaust structure; a mounting seat arranged between the upper cover and the inner cover and located below the sealing turntable; and an elastic abutting member arranged between the sealing turntable and the mounting seat and applying an abutting force towards the upper cover to the sealing turntable so as to keep the sealing turntable in a state of sealing cooperation with the upper cover.

[0006] Applying the technical solution of the present utility model, the upper cover and the inner cover form the main part of the cover assembly. The inner cover includes a cover body and an exhaust structure provided on the cover body. The exhaust structure can rotate synchronously with the cover body. The sealing turntable is arranged between the upper cover and the inner cover and can rotate synchronously with the inner cover. The steam discharged through the exhaust structure will directly pass through the exhaust port and be discharged to the outside of the cover assembly or form condensed water at the sealing turntable. Since the sealing turntable is in sealing cooperation with the upper cover and the exhaust structure, it can prevent steam or condensed water from entering between the upper cover and the inner cover at the connection between the sealing turntable and the exhaust structure or at the connection between the sealing turntable and the upper cover. In addition, the cover assembly further includes a mounting seat and an elastic abutting member. The mounting seat is used to mount the sealing turntable. The elastic abutting member is arranged between the sealing turntable and the mounting seat and abuts against the sealing turntable upward, so that the sealing turntable can always abut against the upper cover to maintain the sealing between the two. That is, through the arrangement of the sealing turntable and the elastic abutting member, the exhaust structure can be arranged eccentrically to the cover assembly, and steam and condensed water can be prevented from entering between the upper cover and the inner cover. Therefore, the technical solution of the present application can effectively solve the problem that the pressure limiting valve in the related art is eccentrically arranged, making it easy for water vapor to enter between the upper cover and the inner cover.

[0007] Further, a receiving recess is provided on the mounting seat, and the elastic abutting member is arranged in the receiving recess. Arranging the elastic abutting member on the mounting seat has the advantage of simple structure.

[0008] Further, a sliding groove is provided on the lower surface of the sealing turntable. When the sealing turntable rotates, the sliding groove moves so that the elastic abutting member abuts against different positions of the bottom wall of the sliding groove. The setting of the sliding groove facilitates the positioning between the sealing turntable and the mounting seat during the assembly of the cover assembly; it can also realize the guiding during the rotation of the sealing turntable.

[0009] Further, the inner cover has a closed cover position and an open cover position. The sealing turntable has a closed cover sealing position corresponding to the closed cover position and an open cover sealing position corresponding to the open cover position. The bottom wall of the sliding groove has an intermediate abutting surface and a closed cover abutting surface and an open cover abutting surface arranged at both ends of the intermediate abutting surface. The intermediate abutting surface protrudes upward relative to the closed cover abutting surface and the open cover abutting surface. When the sealing turntable rotates from the open cover sealing position to the closed cover sealing position, the open cover abutting surface, the intermediate abutting surface, and the closed cover abutting surface are sequentially abutted and cooperated with the elastic abutting member. In this way, when the elastic abutting member cooperates with the intermediate abutting surface, the abutting force applied by the elastic abutting member to the sealing turntable is relatively small, so the resistance of the elastic abutting member relative to the upper cover during rotation is small, making the user's operation feel better; when the elastic abutting member cooperates with the open cover abutting surface or the closed cover abutting surface, the abutting force applied by the elastic abutting member to the sealing turntable is relatively large, ensuring the sealing effect between the elastic abutting member and the upper cover.

[0010] Further, the elastic abutting member includes a ejector rod movably disposed in the receiving recess in the up and down direction and an elastic member disposed between the ejector rod and the bottom wall of the receiving recess. The ejector rod can abut against the lower surface of the sealing turntable under the action of the elastic member, pressing the sealing turntable against the lower surface of the upper cover to ensure the sealing effect between the sealing turntable and the upper cover.

[0011] Further, the lower end of the ejector rod has a first clamping member and a second clamping member disposed at intervals, and a first clamping groove and a second clamping groove are provided on the side wall of the receiving recess. The first clamping member is movably clamped in the first clamping groove in the up and down direction, and the second clamping member is movably clamped in the second clamping groove in the up and down direction. The setting of the above structure ensures the stability of the movement of the ejector rod and can limit the ejector rod from disengaging from the receiving recess upward.

[0012] Further, the first clamping member includes a clamping arm and a clamping block provided at the lower end of the clamping arm; and / or, a guiding inclined surface is provided on the side wall of the receiving recess, and the guiding inclined surface is located above the first clamping groove and extends toward the inside of the receiving recess in the up-down direction. The clamping arm is elastic, and the above setting facilitates the operation of installing the ejector rod into the receiving recess and has the advantages of simple structure; the setting of the guiding inclined surface makes the opening of the receiving recess larger, facilitating the alignment operation of the ejector rod and the receiving recess; and the guiding inclined surface above the first clamping groove can guide and position the first clamping member, enabling the first clamping member to smoothly move into the first clamping groove.

[0013] Further, a guiding post is provided on the bottom wall of the receiving recess, and the elastic member is sleeved on the guiding post; and / or, the top of the ejector rod has an arc-shaped abutting surface. The guiding post can position the elastic member and at the same time ensure the direction of the force exerted by the elastic member on the ejector rod; the setting of the arc-shaped abutting surface can reduce the friction between the ejector rod and the sealing turntable, making the rotation of the sealing turntable smoother.

[0014] Further, the sealing turntable has a plurality of sliding grooves, and the cover assembly includes a plurality of elastic abutting members corresponding to the plurality of sliding grooves one by one. By providing a plurality of sliding grooves and a plurality of elastic abutting members, the stability of the support for the sealing turntable can be ensured.

[0015] Further, the sealing turntable includes a support turntable and a sealing sheet disposed above the support turntable. A sealing convex ring is provided on the sealing sheet, and a sealing convex rib is provided on the lower surface of the upper cover. The sealing convex rib abuts against the sealing convex ring. The sealing sheet is hermetically fitted with the upper cover through the sealing convex ring, so that a concave water collecting portion can be formed in the middle of the sealing sheet to collect condensate and food residues and other dirt generated during the cooking process; the setting of the sealing convex rib can reduce the friction between the sealing convex ring and the upper cover when the sealing turntable rotates, ensure the user's operation feel, and at the same time reduce the wear of the sealing convex ring.

[0016] According to another aspect of the present utility model, a cooking appliance is provided, including a lid assembly, wherein the lid assembly is the above-mentioned lid assembly. The above-mentioned lid assembly can effectively solve the problem that in the related art, the pressure limiting valve is eccentrically arranged, making it easy for water vapor to enter between the upper lid and the inner lid. The cooking appliance with the above-mentioned lid assembly also has the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The present application provides a cover body assembly, Figures 1 to 16 The structural schematic diagram of the first embodiment of the cover body assembly according to the present application is shown.

[0045] As Figure 1 、 Figure 5 and Figure 7 In this embodiment, the cover assembly includes an upper cover 10, an inner cover 20, a sealing turntable 30, a mounting seat 40, and an elastic abutting member 50. Among them, the upper cover 10 has an exhaust port 101; the inner cover 20 is rotatably arranged below the upper cover 10, and the inner cover 20 includes a cover body 21 and an exhaust structure 22 arranged on the cover body 21; the sealing turntable 30 is arranged between the upper cover 10 and the inner cover 20 and can rotate synchronously with the inner cover 20, the exhaust structure 22 passes through the sealing turntable 30, and the sealing turntable 30 is in sealing cooperation with both the upper cover 10 and the exhaust structure 22; the mounting seat 40 is arranged between the upper cover 10 and the inner cover 20 and is located below the sealing turntable 30; the elastic abutting member 50 is arranged between the sealing turntable 30 and the mounting seat 40 and applies an abutting force towards the upper cover 10 to the sealing turntable 30 so that the sealing turntable 30 maintains a state of sealing cooperation with the upper cover 10.

[0046] Applying the technical solution of this embodiment, the upper cover 10 and the inner cover 20 form the main part of the cover assembly. The inner cover 20 includes a cover body 21 and an exhaust structure 22 arranged on the cover body 21. The exhaust structure 22 can rotate synchronously with the cover body 21. The sealing turntable 30 is arranged between the upper cover 10 and the inner cover 20 and can rotate synchronously with the inner cover 20. The steam discharged through the exhaust structure 22 will directly be discharged to the outside of the cover assembly through the exhaust port 101 or form condensed water at the sealing turntable 30. Since the sealing turntable 30 is in sealing cooperation with the upper cover 10 and the exhaust structure 22, it can prevent steam or condensed water from entering between the upper cover 10 and the inner cover 20 from the connection between the sealing turntable 30 and the exhaust structure 22 or from the connection between the sealing turntable 30 and the upper cover 10. In addition, the cover assembly further includes a mounting seat 40 and an elastic abutting member 50. The mounting seat 40 is used to mount the sealing turntable 30. The elastic abutting member 50 is arranged between the sealing turntable 30 and the mounting seat 40 and abuts the sealing turntable 30 upwards, so that the sealing turntable 30 can always be in abutting cooperation with the upper cover 10 to maintain the sealing between the two. That is, through the arrangement of the sealing turntable 30 and the elastic abutting member 50, the exhaust structure 22 can be arranged offset from the center of the cover assembly, and it can prevent steam and condensed water from entering between the upper cover 10 and the inner cover 20. Therefore, the technical solution of this embodiment can effectively solve the problem in the related art that the pressure limiting valve is eccentrically arranged, making it easy for water vapor to enter between the upper cover and the inner cover.

[0047] In this embodiment, the elastic abutting member 50 has a certain floating ability in the up and down direction. When there are certain machining or installation errors in the upper cover 10 or the sealing turntable 30 itself, the floating ability of the elastic abutting member 50 can compensate for these errors, thereby ensuring the sealing effect between the sealing turntable 30 and the upper cover 10.

[0048] AsFigure 1 , Figure 5 and Figure 6 As shown in Figure 1 , Figure 5 and Figure 6 , the upper cover 10 includes a face cover 12 and a lining 13. The lining 13 is disposed between the face cover 12 and the cover body 21. The top of the sealing turntable 30 is in sealing cooperation with the face cover 12. The mounting seat 40 is located between the lining 13 and the face cover 12 and is connected to the lining 13 and / or the face cover 12. Connecting the mounting seat 40 to the lining 13 and / or the face cover 12 can relatively fix the position of the mounting seat 40 with respect to the upper cover 10, so that the sealing turntable 30 will not change its position in the vertical direction as the pressure in the cooking cavity increases or decreases, ensuring the sealing effect between the sealing turntable 30 and the upper cover 10.

[0049] It should be noted that the above-mentioned "the mounting seat 40 is connected to the lining 13 and / or the face cover 12" means that the mounting seat 40 and the lining 13 and / or the face cover 12 are integrally formed structures, or the mounting seat 40 is an independently provided structure and is connected to the lining 13 and / or the face cover 12 through a connecting member.

[0050] As Figure 1 and Figure 16 shown, in this embodiment, the cover assembly further includes a cover 14. An installation opening 121 is provided on the face cover 12. The cover 14 is detachably disposed at the installation opening 121 and can block the installation opening 121. The exhaust port 101 is formed on the cover 14 or between the cover 14 and the face cover 12. The cover 14 can block the sealing turntable 30 and the exhaust structure 22, ensuring the aesthetics of the cover assembly. During the exhaust process, part of the steam discharged from the upper end of the exhaust structure 22 condenses on the sealing turntable 30 to form condensed water, and part of the steam is discharged from the exhaust port 101 to the external space.

[0051] In the present application, the rotating structure (i.e., the sealing turntable 30) is disposed between the face cover 12 and the inner cover 20, and a cover 14 is provided above the rotating structure to block it. The cover 14 does not need to rotate synchronously with the inner cover 20 and the sealing turntable 30, so that the appearance above the cover assembly is consistent, improving the user experience.

[0052] Of course, in an embodiment not shown in the figure, the cover can also be not provided and the exhaust port can be directly provided on the face cover.

[0053] As Figure 5 and Figures 7 to 10 shown, a receiving recess 41 is provided on the mounting seat 40. The elastic abutting member 50 is disposed in the receiving recess 41. Disposing the elastic abutting member 50 on the mounting seat 40 has the advantage of simple structure.

[0054] As Figure 7As shown, the mounting base 40 includes a support disk body 43 and a connecting arm 44 disposed outside the support disk body 43. The support disk body 43 includes a bottom plate 431 and a vertical plate 432 disposed outside the bottom plate. An avoidance opening 433 for avoiding the exhaust structure 22 is provided on the bottom plate 431. The accommodation recess 41 is provided on the vertical plate 432, and the connecting arm 44 is connected to the vertical plate 432. In this embodiment, the mounting base 40 is connected to the face cover 12 by screws passing through the connecting arm 44 and the face cover 12. As Figure 5 and Figures 7 to 11 shown, a sliding groove 31 is provided on the lower surface of the sealing turntable 30. When the sealing turntable 30 rotates, the sliding groove 31 moves so that the elastic abutting member 50 abuts against different positions of the bottom wall of the sliding groove 31. By providing the sliding groove 31 matching with the elastic abutting member 50 on the lower surface of the sealing turntable 30, during the assembly of the cover assembly, it is convenient to position between the sealing turntable 30 and the mounting base 40; and it can also realize the guiding during the rotation of the sealing turntable 30.

[0055] As Figure 5 and Figures 7 to 12 shown, the inner cover 20 has a closed cover position and an open cover position. The sealing turntable 30 has a closed cover sealing position corresponding to the closed cover position and an open cover sealing position corresponding to the open cover position. The bottom wall of the sliding groove 31 has an intermediate abutting surface 311 and a closed cover abutting surface 312 and an open cover abutting surface 313 provided at both ends of the intermediate abutting surface 311. The intermediate abutting surface 311 protrudes upward relative to the closed cover abutting surface 312 and the open cover abutting surface 313. When the sealing turntable 30 rotates from the open cover sealing position to the closed cover sealing position, the open cover abutting surface 313, the intermediate abutting surface 311, and the closed cover abutting surface 312 are sequentially abutted and cooperated with the elastic abutting member 50. The open cover abutting surface 313 and the closed cover abutting surface 312 are lower than the intermediate abutting surface 311. Thus, when the elastic abutting member 50 cooperates with the intermediate abutting surface 311 (that is, when the inner cover 20 rotates from the open cover position to the closed cover position or from the closed cover position to the open cover position), the abutting force exerted by the elastic abutting member 50 on the sealing turntable 30 is relatively small. In this way, the resistance when the elastic abutting member 50 rotates relative to the upper cover 10 is small, making the user's operation feel better; when the elastic abutting member 50 cooperates with the open cover abutting surface 313 or the closed cover abutting surface 312 (that is, when the inner cover 20 is in the open cover position or the closed cover position), the abutting force exerted by the elastic abutting member 50 on the sealing turntable 30 is relatively large, ensuring the sealing effect between the elastic abutting member 50 and the upper cover 10.

[0056] Preferably, the convex height of the highest point of the intermediate abutting surface 311 relative to the open cover abutting surface 313 and the closed cover abutting surface 312 is greater than or equal to 0.5 mm to reduce the rotational resistance during the process of the inner cover 20 rotating from the open cover position to the closed cover position or from the closed cover position to the open cover position and reduce the friction.

[0057] Specifically, in this embodiment, when the inner lid 20 is in the closed lid position and the cooking appliance is cooking, steam is discharged through the exhaust structure 22, and the elastic abutting member 50 causes the sealing turntable 30 to reliably abut against the lower surface of the upper lid 10, which can prevent steam and the condensed water formed by the steam from entering between the inner lid 20 and the upper lid 10 through the connection between the upper lid 10 and the sealing turntable 30; when the inner lid 20 is in the open lid position, since the user will flip the lid assembly to open the lid, the elastic abutting member 50 causes the sealing turntable 30 to reliably abut against the lower surface of the upper lid 10, which can prevent the condensed water from entering between the inner lid 20 and the upper lid 10 through the connection between the upper lid 10 and the sealing turntable 30 when the user flips the lid assembly; when the inner lid 20 is switched between the open lid position and the closed lid position, the sealing turntable 30 can be in sealing cooperation with the upper lid 10 to ensure the sealing effect, or the sealing turntable 30 can also not be in sealing cooperation with the upper lid 10, which can reduce the operating resistance when the user drives the inner lid 20 to rotate and has a better feel.

[0058] As Figures 7 to 10 shown, the elastic abutting member 50 includes a ejector rod 51 movably arranged in the receiving recess 41 in the up and down direction and an elastic member 52 arranged between the ejector rod 51 and the bottom wall of the receiving recess 41. Among them, the ejector rod 51 can abut against the lower surface of the sealing turntable 30 (specifically, the groove top wall of the chute 31) under the action of the elastic member 52, pressing the sealing turntable 30 against the lower surface of the upper lid 10 to ensure the sealing effect between the sealing turntable 30 and the upper lid 10.

[0059] In the state where the sealing turntable 30 and the mounting seat 40 are not assembled, the ejector rod 51 protrudes upward from the top surface of the receiving recess 41, preferably, the protruding height is greater than or equal to 2 mm.

[0060] As Figure 9 and Figure 10 shown, the lower end of the ejector rod 51 has a first clamping member 53 and a second clamping member 54 arranged at intervals, and a first clamping groove 411 and a second clamping groove 412 are arranged on the side wall of the receiving recess 41. The first clamping member 53 is movably clamped in the first clamping groove 411 in the up and down direction, and the second clamping member 54 is movably clamped in the second clamping groove 412 in the up and down direction. The first clamping groove 411 can guide the first clamping member 53 and prevent the first clamping member 53 from disengaging upward at the same time. The second clamping groove 412 can guide the second clamping member 54 and prevent the second clamping member 54 from disengaging upward at the same time, thereby ensuring the stability of the movement of the ejector rod 51 and being able to limit the ejector rod 51 from disengaging upward from the receiving recess 41.

[0061] As Figure 9As shown, the first card member 53 includes a card arm 531 and a card block 532 provided at the lower end of the card arm 531; similarly, the second card member 54 also includes a card arm and a card block provided at the lower end of the card arm. When installing the ejector rod 51, the card arms of the first card member 53 and the second card member 54 have a certain elasticity and can contract inward, so that the first card member 53 and the second card member 54 can enter the receiving recess 41. When the card block 532 of the first card member 53 moves to the first card slot 411 and the card block of the second card member 54 moves to the second card slot 412, the two card arms expand outward under the action of their own elasticity, so that the two card blocks are respectively engaged with the corresponding card slots. The above setting facilitates the operation of installing the ejector rod 51 into the receiving recess 41 and has the advantage of simple structure.

[0062] As Figure 9 and Figure 10 shown, a guiding inclined surface 413 is provided on the side wall of the receiving recess 41. The guiding inclined surface 413 is located above the first card slot 411 and extends toward the inside of the receiving recess 41 in the up-down direction. Similarly, a guiding inclined surface is also provided above the second card slot 412 corresponding to the receiving recess 41. The setting of the two guiding inclined surfaces makes the opening of the receiving recess 41 larger, which facilitates the alignment operation of the ejector rod 51 and the receiving recess 41. Moreover, the guiding inclined surface 413 above the first card slot 411 can guide and position the first card member 53, so that the first card member 53 can smoothly move to the first card slot 411; the guiding inclined surface above the second card slot 412 can guide and position the second card member 54, so that the second card member 54 can smoothly move to the second card slot 412.

[0063] As Figures 7 to 10 shown, a guiding post 42 is provided on the bottom wall of the receiving recess 41. The elastic member 52 is sleeved on the guiding post 42. Specifically, in this embodiment, the elastic member 52 is a compression spring. The elastic member 52 is sleeved on the guiding post 42, which can position the elastic member 52 and at the same time ensure the direction of the force exerted by the elastic member 52 on the ejector rod 51, ensuring the smooth movement of the ejector rod 51 and the abutting effect on the sealing turntable 30.

[0064] As Figure 9 shown, the top of the ejector rod 51 has an arc-shaped abutting surface 511. Since the sealing turntable 30 will move horizontally relative to the ejector rod 51, setting the arc-shaped abutting surface 511 at the top of the ejector rod 51 can reduce the friction between the ejector rod 51 and the sealing turntable 30, making the rotation of the sealing turntable 30 smoother.

[0065] As Figure 7 and Figure 11As shown, the sealed turntable 30 has a plurality of sliding grooves 31, and the cover assembly includes a plurality of elastic abutting members 50 provided in one-to-one correspondence with the plurality of sliding grooves 31. By providing the plurality of sliding grooves 31 and the plurality of elastic abutting members 50, the stability of the support for the sealed turntable 30 can be ensured.

[0066] Specifically, the above-mentioned "plurality" refers to two or more. In this embodiment, the number of the sliding grooves 31 and the elastic abutting members 50 is three each. As Figure 11 shown, in this embodiment, the centers of the plurality of sliding grooves 31 enclose an annular structure, and this annular structure is not limited to a circle, and can also be an ellipse or other shapes.

[0067] As Figure 5 、 Figure 6 and Figures 13 to 15 shown, the sealed turntable 30 includes a support turntable 32 and a sealing sheet 33 provided above the support turntable 32. A sealing convex ring 331 is provided on the sealing sheet 33, and a sealing convex rib 11 is provided on the lower surface of the upper cover 10. The sealing convex rib 11 abuts and cooperates with the sealing convex ring 331. The sealing sheet 33 is hermetically cooperated with the upper cover 10 through the sealing convex ring 331, so that a concave water collecting part can be formed in the middle of the sealing sheet 33 to collect condensate and food residues and other dirt generated during the cooking process, and prevent the condensate and food residues and other dirt from remaining on the sealing surface (that is, the top surface of the sealing convex ring 331) and affecting the smooth rotation of the sealed turntable 30 and the sealing effect between the sealed turntable 30 and the upper cover 10. By providing the sealing convex rib 11 on the lower surface of the upper cover 10 to cooperate with the sealing convex ring 331, the friction between the sealing convex ring 331 and the upper cover 10 when the sealed turntable 30 rotates can be reduced, the operation feel of the user can be ensured, and at the same time, the wear of the sealing convex ring 331 can be reduced, and the service life of the sealed turntable 30 can be ensured.

[0068] The sealing sheet 33 itself is a flexible structure and can maintain a good sealing effect with the sealing convex rib 11 on the upper cover 10. By supporting the sealing sheet 33 through the support turntable 32, the installation of the sealed turntable 30 is facilitated.

[0069] Specifically, the upward convex height of the sealing convex ring 331 is greater than or equal to 5 mm, so that the concave water collecting part formed in the middle of the sealing sheet 33 has a large enough water storage space.

[0070] As Figures 1 to 3As shown, the exhaust structure 22 includes an exhaust pipe 221 passing through the cover body 21 and the bottom wall of the concave water collecting part, and a pressure limiting valve 222 arranged above the exhaust pipe 221. The pressure limiting valve 222 is located inside the concave water collecting part. During cooking, when the pressure inside the cooking cavity increases or decreases, the cover body 21 will float up and down, and then drive the exhaust structure 22 to float up and down as well. Since the sealing piece 33 is a flexible structure, the bottom wall of the concave water collecting part can be deformed to adapt to the up and down floating of the exhaust structure 22, thus avoiding setting the entire sealing turntable 30 as a structure that can float up and down.

[0071] Specifically, in this embodiment, the user can drive the cover body 21 to rotate by operating the operating member. The exhaust pipe 221 is fixedly arranged on the cover body 21. When the cover body 21 rotates, it drives the sealing turntable 30 to rotate through the exhaust pipe 221.

[0072] As Figure 1 、 Figure 4 and Figure 11 shown, in this embodiment, the exhaust structure 22 is a double exhaust valve structure. One exhaust valve is concentric with the cover body 21, and the other exhaust valve is eccentric with the cover body 21. The avoidance opening 433 on the mounting seat 40 can avoid the exhaust structure 22.

[0073] Two through holes for the two exhaust pipes 221 of the double exhaust valve structure to pass through are arranged on the support turntable 32. One through hole is concentric with the cover body 21, and the other through hole is eccentric with respect to the cover body 21. When the cover body 21 rotates, the through hole concentric with the cover body 21 and the exhaust valve remain in the same position, and the exhaust valve of the through hole eccentric with respect to the cover body 21 moves along an arc-shaped trajectory with the center of the cover body 21 as the center of the arc. Correspondingly, two through holes corresponding to the double exhaust valve structure are also arranged on the sealing piece 33.

[0074] That is, in this embodiment, the rotation center of the sealing turntable 30 is inside the sealing turntable 30. Of course, in an embodiment not shown in the figure, the rotation center of the sealing turntable can also be outside the sealing turntable.

[0075] As Figures 5 to 7 and Figure 13As shown, the concave water collecting part has a first sinking part 332, a second sinking part 333 and a connecting wall 334. Among them, the first sinking part 332 is an annular structure, the second sinking part 333 is arranged in the middle of the annular structure and is lower than the first sinking part 332, and the first sinking part 332 and the second sinking part 333 are connected by the connecting wall 334. The inner lid 20 further includes a cold air exhausting structure 23 penetrating through the lid body 21, and the sealing turntable 30 further includes a push rod 36 sealingly penetrating through the first sinking part 332, and the push rod 36 is located above the cold air exhausting structure 23. Specifically, before the upper pressure inside the cooking appliance, the cold air in the cooking cavity can be exhausted through the cold air exhausting structure 23. When the pressure in the cooking cavity rises to a certain degree, the cold air exhausting structure 23 floats under the action of the pressure in the cooking cavity. After the pressure in the cooking cavity drops at the end of cooking, the cold air exhausting structure 23 generally falls under the action of its own gravity. However, in actual use, the cold air exhausting structure 23 often has difficulty falling, which affects the rotation of the inner lid 20 to the open lid position. By arranging the push rod 36 on the first sinking part 332, the user can press down the push rod 36 to press down the cold air exhausting structure 23 to open the lid smoothly. An avoidance part 322 is arranged on the support turntable 32 corresponding to the position of the push rod 36, and the push rod 36 penetrates through the avoidance part 322. The avoidance part 322 can be a concave structure or an avoidance opening structure, so that the push rod 36 and the first sinking part 332 connected to the push rod 36 can have a certain downward movement ability.

[0076] A second sinking part 333 lower than the first sinking part 332 is arranged, so that dirt such as condensed water and food residues first accumulates in the space formed by the second sinking part 333 and the connecting wall 334, avoiding dirt such as condensed water and food residues remaining above the push rod 36 and affecting the user experience.

[0077] The exhaust pipe 221 of the exhaust structure 22 penetrates through the second sinking part 333, and the pressure limiting valve 222 is located above the second sinking part 333, so that the upper part of the exhaust structure 22 can sink into the range of the sealing turntable 30 as much as possible, avoiding protruding upward from the face cover 12.

[0078] Specifically, in this embodiment, the shape of the concave water collecting part (specifically, the outer contour shape of the first sinking part 332) is adapted to the shape of the installation opening 121 provided on the face cover 12, and the shape of the sealing rib 11 (specifically, the first ring rib 111) is adapted to the shape of the installation opening 121. When the inner lid 20 is in the closed lid position and the sealing turntable 30 is in the closed lid sealing position ( Figure 2the position shown in), the concave water collecting part is directly opposite to the mounting opening 121. Such a setting makes the top area of the sealing convex ring 331 inside the sealing rib 11 smaller at this time, avoiding dirt such as condensed water and food residues from remaining on the top surface of the sealing convex ring 331. When the inner lid 20 is in the open position and the sealing turntable 30 is in the open lid sealing position ( Figure 3 the position shown in, ) the concave water collecting part is arranged offset from the mounting opening 121, and the top surface of a part of the sealing convex ring 331 is exposed from the mounting opening 121.

[0079] As Figure 6 shown, the thickness of the second sinking part 333 is between 0.3 mm and 1 mm, so that the second sinking part 333 has a large deformation ability to adapt to the up and down floating of the exhaust structure 22. Preferably, the thickness of the second sinking part 333 can be 0.3 mm, 0.5 mm, 0.8 mm or 1 mm.

[0080] As Figure 6 shown, the thickness of the connecting wall 334 is between 0.5 mm and 2 mm; a large amount of steam is generated during the cooking process, and thus the amount of condensed water is also relatively large. The user can clean the dirt such as condensed water and food residues collected in the concave water collecting part by himself. The thickness of the connecting wall 334 is within the above range, so that it has a certain strength to avoid taking out the sealing piece 33 when the user is cleaning. Preferably, the thickness of the connecting wall 334 can be 0.5 mm, 1 mm, 1.5 mm or 2 mm.

[0081] As Figure 13 shown, the sealing turntable 30 includes a supporting turntable 32, an annular pressing plate 34 and a sealing piece 33. The supporting turntable 32 supports below the sealing piece 33, and the sealing piece 33 is clamped between the annular pressing plate 34 and the supporting turntable 32. Among them, the supporting turntable 32 and the annular pressing plate 34 are hard structures, and the sealing piece 33 is a flexible structure. The sealing piece 33 is positioned and fixed by clamping the sealing piece 33 between the supporting turntable 32 and the annular pressing plate 34, so that the overall structure of the sealing turntable 30 is stable, facilitating the installation and positioning of the sealing turntable 30.

[0082] In this embodiment, the annular pressing plate 34, the sealing piece 33 and the supporting turntable 32 are arranged in sequence from top to bottom. Of course, in an embodiment not shown in the figure, the annular pressing plate can also be arranged below the supporting turntable. Specifically, a slot structure with an inward opening can be provided at the lower end of the sealing piece, the outer edge of the supporting turntable is inserted into the slot structure, and the lower wall surface of the slot structure is pressed on the supporting turntable by an annular pressing plate arranged below the supporting turntable to fix the sealing piece.

[0083] As Figure 12 and Figure 13As shown, the sealing turntable 30 further includes positioning posts 341 disposed on the annular pressing plate 34 and passing through the support turntable 32 and the sealing sheet 33. Before fixing the sealing turntable 30, the support turntable 32, the annular pressing plate 34, and the sealing sheet 33 can be positioned first through the positioning posts 341 to simplify the subsequent fixing operation.

[0084] Specifically, as Figure 12 and Figure 13 shown, the sealing sheet 33 further includes a connecting edge disposed on the outer periphery of the sealing convex ring 331. The connecting edge is clamped between the annular pressing plate 34 and the support turntable 32. The positioning posts 341 are disposed on the lower surface of the annular pressing plate 34. A first connecting hole is provided on the connecting edge, and a second connecting hole is provided on the support turntable 32. The positioning posts 341 sequentially pass through the first connecting hole and the second connecting hole to position the support turntable 32, the annular pressing plate 34, and the sealing sheet 33.

[0085] As Figure 11 and Figure 12 shown, the sealing turntable 30 further includes fasteners 35 passing through the support turntable 32, the sealing sheet 33, and the annular pressing plate 34. The support turntable 32, the annular pressing plate 34, and the sealing sheet 33 are fixed by the fasteners 35 to ensure the stability of the overall structure of the sealing turntable 30.

[0086] As Figure 14 and Figure 15 shown, the sealing rib 11 includes a first ring rib 111 and a second ring rib 112. When the sealing turntable 30 is in the closed - cover sealing position, the first ring rib 111 abuts against the sealing convex ring 331. When the sealing turntable 30 is in the open - cover sealing position, the second ring rib 112 abuts against the sealing convex ring 331. By providing the first ring rib 111 and the second ring rib 112, the sealing effect between the sealing turntable 30 and the upper cover 10 can be ensured in both the closed - cover sealing position and the open - cover sealing position.

[0087] As Figure 14 and Figure 15 shown, the sealing rib 11 includes a first rib body 113, a second rib body 114, and a third rib body 115. The first rib body 113 and the second rib body 114 enclose to form the first ring rib 111. The third rib body 115 is located outside the second rib body 114 and encloses with the first rib body 113 to form the second ring rib 112. That is, the first ring rib 111 and the second ring rib 112 share the first rib body 113, making the structure of the sealing rib 11 simple.

[0088] Specifically, the sealing turntable 30 rotates from the closed - cover sealing position to the open - cover sealing position along the direction from the first rib body 113 to the third rib body 115. That is, the third rib body 115 is disposed on one side of the rotation direction of the sealing turntable 30.

[0089] Correspondingly, in order to reduce the space occupied by the sealing turntable 30 inside the cover assembly and leave an outlet space for setting other structures, the top surface of the sealing convex ring 331 that cooperates with the first rib 113 can be set wider, and the top surface of the sealing convex ring 331 that cooperates with the second rib 114 and the third rib 115 can be set narrower. Specifically, the top surface of the sealing convex ring 331 includes a first sealing area and a second sealing area. The width of the first sealing area is smaller than that of the second sealing area. The first sealing area is correspondingly arranged with the second rib 114 and the third rib 115, and the second sealing area is correspondingly arranged with the first rib 113.

[0090] Since the top surface of the sealing convex ring 331 is in abutting cooperation with the sealing convex rib 11, the sealing convex ring 331 will be worn. In order to reduce the wear of the sealing convex ring 331, the top surface of the sealing convex ring 331 can be polished and / or oiled to extend the service life of the sealing turntable 30.

[0091] Specifically, in this embodiment, both the first ring rib 111 and the second ring rib 112 are in interference fit with the sealing convex ring 331, and the interference amount is between 0.3 mm and 1 mm. By making both the first ring rib 111 and the second ring rib 112 in interference fit with the sealing convex ring 331, the sealing effect is ensured. Preferably, the interference amount between the first ring rib 111 and the sealing convex ring 331 can be 0.3 mm, 0.5 mm, 0.8 mm or 1 mm; the interference amount between the second ring rib 112 and the sealing convex ring 331 can be 0.3 mm, 0.5 mm, 0.8 mm or 1 mm.

[0092] As Figure 5 shown, the sealing convex ring 331 and the support turntable 32 are arranged at intervals. The sealing convex ring 331 and the support turntable 32 are arranged at intervals, so that the sealing convex ring 331 has a certain ability to deform downward, which can compensate for the processing and installation errors of the upper cover 10 and the sealing turntable 30 and ensure the sealing effect between the sealing turntable 30 and the upper cover 10.

[0093] Furthermore, in order to ensure the elastic deformation ability and structural strength of the sealing convex ring 331 so that the sealing convex ring 331 can always be in sealing cooperation with the upper cover 10, a support rib that abuts against the support turntable can be arranged below the sealing convex ring.

[0094] As Figure 5 and Figure 13 shown, a support convex rib 321 is arranged on the support turntable 32, and the support convex rib 321 extends below the sealing convex ring 331. The support convex rib 321 can position the sealing convex ring 331 in the lateral direction, so that the sealing convex ring 331 remains in the position of abutting against the sealing convex rib 11.

[0095] Specifically, there can be multiple (two or more) supporting ribs 321, and the multiple supporting ribs 321 are nested and fitted. Since the sealing convex ring 331 has a certain width, the supporting ribs 321 also need to cover a sufficient area to ensure the positioning effect on the sealing convex ring 331. By providing multiple supporting ribs 321, the positioning effect on the sealing convex ring 331 can be ensured, and at the same time, the shrinkage phenomenon caused by the excessive width of a single supporting rib 321 can be avoided. As Figure 13 shown, in this embodiment, two supporting ribs 321 are provided, and a plurality of connecting ribs are provided between the two supporting ribs 321.

[0096] Among them, as Figure 5 shown, the thickness of the top wall of the sealing convex ring 331 is between 1.5 mm and 3.5 mm; the thickness of the top wall of the sealing convex ring 331 within this range can balance the deformation ability and structural strength of the sealing convex ring 331, so that the sealing convex ring 331 can always be in sealing fit with the sealing rib 11. In addition, since the sealing convex ring 331 will move relative to the sealing rib 11, the sealing convex ring 331 will be worn to a certain extent. Setting the sealing convex ring 331 thicker can ensure the service life of the sealing turntable 30. Preferably, the thickness of the top wall of the sealing convex ring 331 can be 1.5 mm, 2 mm, 2.5 mm, 3 mm or 3.5 mm.

[0097] As Figure 5 shown, the distance between the lower surface of the top wall of the sealing convex ring 331 and the upper surface of the supporting rib 321 is between 0.5 mm and 2.5 mm. The distance between the lower surface of the top wall of the sealing convex ring 331 and the upper surface of the supporting rib 321 within this range can balance the deformation ability and structural strength of the sealing convex ring 331, so that the sealing convex ring 331 can always be in sealing fit with the sealing rib 11. Preferably, the distance can be 0.5 mm, 1 mm, 1.5 mm, 2 mm or 2.5 mm.

[0098] Figure 17 FIG. shows a schematic structural diagram of the sealing turntable 30 according to the second embodiment of the cover assembly of the present invention. The following will describe the parts of the second embodiment of the cover assembly of the present application that are different from the first embodiment with reference to the accompanying drawings. The same content in the two embodiments will not be described again.

[0099] Specifically, the structural composition of the sealing turntable 30 in this embodiment is different from that in the first embodiment. In the first embodiment, the sealing turntable 30 is a three-layer structure; in this embodiment, the sealing turntable 30 is a two-layer structure.

[0100] As Figure 17As shown in the figure, the sealing turntable 30 includes a supporting turntable 32 and a sealing piece 33 disposed on the supporting turntable 32. An installation hole is provided on the supporting turntable 32. A connecting column 335 is disposed below the sealing piece 33 and passes through the installation hole. The connecting column 335 includes a column body portion and a stop block provided at the lower end of the column body portion and in stop cooperation with the lower surface of the supporting turntable 32. Specifically, by providing the connecting column 335 below the sealing piece 33 to achieve the connection with the supporting turntable 32, fasteners such as screws can be omitted, simplifying the structure of the sealing turntable 30.

[0101] As Figure 17 shown in the figure, in the up-down direction, the cross-sectional dimension of the stop block gradually decreases, and the dimension of the upper end surface of the stop block is larger than the dimension of the installation hole. When assembling the sealing piece 33 and the supporting turntable 32, align the lower end of the stop block with the installation hole, and the stop block is deformed by extrusion, passes through the installation hole, and then is in stop cooperation with the lower surface of the supporting turntable 32.

[0102] The setting of the stop block prevents the user from taking out the sealing piece 33 when cleaning the condensed water and dirt inside the sealing turntable 30.

[0103] As Figure 17 shown in the figure, the sealing piece 33 has a sealing convex ring 331 and a concave water collecting portion 336 located inside the sealing convex ring 331. The exhaust structure 22 passes through the concave water collecting portion 336.

[0104] The present application also provides a cooking appliance. An embodiment of the cooking appliance of the present application includes a lid assembly, wherein the lid assembly is the above-mentioned lid assembly. The above-mentioned lid assembly can effectively solve the problem in the related art that the pressure limiting valve is eccentrically arranged, making it easy for water vapor to enter between the upper lid and the inner lid. The cooking appliance having the above-mentioned lid assembly also has the above-mentioned advantages.

[0105] Specifically, in this embodiment, the cooking appliance is a pressure cooking appliance. Of course, in an embodiment not shown in the figure, the cooking appliance can also be products such as an electric rice cooker, a low-pressure rice cooker, a soymilk machine, a food processor, a stir-fry machine, an electric slow cooker, a multi-functional pot, etc.

[0106] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the protection scope of the present utility model; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0107] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper", etc. can be used here to describe the spatial positional relationship of a device or feature shown in the figure with other devices or features. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figure for the device. For example, if the device in the figure is inverted, the device described as "above" or "over" other devices or structures will then be positioned "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the corresponding explanations are made for the spatial relative descriptions used here.

[0108] In addition, it should be noted that the use of terms such as "first", "second", etc. to limit components is only for the convenience of differentiating the corresponding components. Without additional statements, the above terms have no special meanings, and thus cannot be construed as limiting the protection scope of the present utility model.

[0109] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
