Description

Technical Field

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

[0002] In the related art, the pressure cooking appliance generally includes an exhaust structure, which can cooperate with the heating structure to adjust the cooking pressure in the cooking cavity. After heating is completed, the exhaust structure can exhaust air to quickly reduce the pressure in the cooking cavity to achieve rapid opening of the lid.

[0003] For the solution in which the exhaust structure is set away from the center of the cover assembly, since the exhaust structure needs to rotate synchronously with the steel cover, the exhaust structure rotates in an arc relative to the surface cover. In order to prevent the steam discharged from the exhaust structure from entering between the surface cover and the steel cover, the steel cover can be set as a split structure so that the exhaust structure remains stationary. The steel cover specifically includes a cover body that is concentrically arranged with the surface cover and does not rotate, and a locking ring that is rotatable relative to the cover body. The exhaust structure is set at a position close to the edge of the cover body, and the steel cover and the pot body are engaged or unengaged by rotating the locking ring. In this way, the exhaust structure can remain stationary so as to facilitate the setting of a sealing structure around the exhaust structure. However, due to the need to consider issues such as pressure bearing, the split steel cover has a complex structure, high cost, and is not easy to clean. Utility Model Content

[0004] The main purpose of the utility model is to provide a cover assembly and a cooking utensil having the same, so as to solve the problem that the steel cover in the related art has a complex structure and a high cost.

[0005] In order to achieve the above-mentioned purpose, according to one aspect of the utility model, a cover body assembly is provided, including: an upper cover, having a steam port; a steel cover, rotatably arranged below the upper cover and having a cover-closing position and a cover-opening position; an exhaust structure, arranged on the steel cover; a rotating seal, arranged between the upper cover and the steel cover and capable of rotating synchronously with the steel cover, the rotating seal having a first sealing position corresponding to the cover-closing position and a second sealing position corresponding to the cover-opening position, the rotating seal having an exhaust area corresponding to the steam port, the exhaust structure sealingly passing through the rotating seal and being located in the exhaust area, wherein, when the rotating seal is located at the first sealing position and the second sealing position, the top of the rotating seal is sealed with the upper cover to seal the exhaust area.

[0006] By applying the technical solution of the utility model, the cover assembly includes a rotating seal arranged between the upper cover and the steel cover, and the rotating seal can cooperate with the exhaust structure arranged on the steel cover and the upper cover seal, thereby preventing the steam generated during the exhaust process from entering between the upper cover and the steel cover, and the rotating seal can rotate synchronously with the steel cover, so that the exhaust structure can also be set as a rotating structure, that is, the steel cover, the exhaust structure and the rotating seal can rotate synchronously, so that there is no need to set the steel cover as a split structure as generally in the related art, and the steel cover can be directly set as an integrated structure, which simplifies the structure of the steel cover while ensuring the sealing effect between the exhaust structure and the upper cover, and reduces the complexity and cost of the steel cover. Therefore, the technical solution of the present application can effectively solve the problem of complex structure and high cost of the steel cover in the related art.

[0007] Furthermore, the cover assembly further comprises a mounting seat, which is arranged between the upper cover and the steel cover and supported below the rotating seal. The mounting seat is supported below the rotating seal and, together with the upper cover, limits the rotating seal in the up and down directions, so that the rotating seal can only move in the lateral direction to rotate synchronously with the steel cover.

[0008] Furthermore, the upper cover includes a surface cover and a lining cover, the lining cover is arranged between the surface cover and the steel cover, the top of the rotating seal is sealed with the surface cover, and the mounting seat is located between the lining cover and the surface cover and connected to the lining cover and / or the surface cover. This arrangement can make the position of the mounting seat and the upper cover relatively fixed, so that the rotating seal will not change position in the up and down direction with the pressure increase or decrease in the cooking cavity, thereby ensuring the sealing effect between the rotating seal and the upper cover.

[0009] Furthermore, the mounting seat includes a support plate and a connecting arm arranged outside the support plate, and a support protrusion is arranged on the support plate to support the bottom of the rotating seal. The support protrusion is arranged on the support plate, which can reduce the support area between the support plate and the rotating seal, thereby reducing the rotation resistance of the rotating seal, so that the user has a better operating feel when driving the steel cover and the rotating seal to rotate.

[0010] Furthermore, the supporting protrusion includes an elastic convex point, and the elastic convex point applies a resisting force toward the face cover to the rotating seal. The elastic convex point has a certain floating ability in the up and down directions, and the floating ability of the elastic convex point can compensate for the processing and installation errors of the face cover and the rotating seal, thereby ensuring the sealing effect between the rotating seal and the face cover.

[0011] Furthermore, the rotating seal comprises a supporting turntable and a sealing sheet arranged on the supporting turntable, the sealing sheet has a top sealing surface, an annular sealing convex rib is arranged on the upper cover, and the top sealing surface and the annular sealing convex rib are abutted against each other. The arrangement of the annular sealing convex rib can reduce the matching area between the top sealing surface and the upper cover, reduce the rotation resistance, and thus make the user's operation feel better.

[0012] Furthermore, the annular sealing rib includes a first annular retaining rib and a second annular retaining rib. When the rotating seal is located at the first sealing position, the first annular retaining rib abuts against the top sealing surface, and when the rotating seal is located at the second sealing position, the second annular retaining rib abuts against the top sealing surface. By providing the first annular retaining rib and the second annular retaining rib, the sealing effect between the rotating seal and the upper cover can be ensured in the first sealing position and the second sealing position.

[0013] Furthermore, the sealing sheet includes a sealing convex ring, a top sealing surface is formed on the sealing convex ring, and the sealing convex ring is spaced apart from the supporting rotating disk. The sealing convex ring is spaced apart from the supporting rotating disk, so that the sealing convex ring has a certain ability to deform downward, and can compensate for the processing and installation errors of the upper cover and the rotating seal, thereby ensuring the sealing effect between the rotating seal and the upper cover.

[0014] Furthermore, the sealing sheet also includes a support rib disposed below the sealing convex ring and abutting against the supporting rotating disk. The support rib can position the sealing convex ring in the transverse direction so that the support rib remains in a position abutting against the annular sealing rib.

[0015] Furthermore, a supporting convex rib is provided on the supporting turntable, and the supporting convex rib extends below the sealing convex ring, wherein the thickness of the sealing convex ring is between 1.5 mm and 3.5 mm; and / or the distance between the lower surface of the sealing convex ring and the upper surface of the supporting rib is between 0.5 mm and 2.5 mm. The above arrangement can take into account the deformation ability and structural strength of the sealing convex ring, so that the sealing convex ring can always be sealed with the annular sealing convex rib.

[0016] Furthermore, the sealing sheet has a water collecting recess located inside the sealing convex ring, and the exhaust structure is arranged in the water collecting recess. The water collecting recess is arranged concave relative to the top sealing surface, so that condensed water and food residues generated during cooking will be collected in the water collecting recess.

[0017] Further, the thickness of the bottom wall of the water collecting recess is between 0.3mm and 1mm; and / or, the thickness of the side wall of the water collecting recess is between 0.5mm and 2mm; and / or, the side wall of the water collecting recess protrudes downward from the bottom wall of the water collecting recess, and a mounting recess is provided on the supporting turntable, and the lower end of the side wall of the water collecting recess extends into the mounting recess. The thickness of the bottom wall of the water collecting recess is within the above range, so that the bottom wall of the water collecting recess has a large deformation capacity to adapt to the up and down floating of the exhaust structure. The thickness of the side wall of the water collecting recess is within the above range and the lower end of the side wall of the water collecting recess extends into the mounting recess, which can prevent the user from taking the water collecting recess out when cleaning.

[0018] Furthermore, the rotary seal comprises a supporting rotary disc, an annular pressure plate and a sealing sheet, wherein the supporting rotary disc is supported below the sealing sheet, and the sealing sheet is sandwiched between the annular pressure plate and the supporting rotary disc. The sealing sheet is clamped by the supporting rotary disc and the annular pressure plate to achieve positioning and fixing of the sealing sheet, so that the overall structure of the rotary seal is stable, and the installation and positioning of the rotary seal is convenient.

[0019] Furthermore, the rotary seal also includes a positioning column arranged between the supporting rotary disk, the annular pressure plate and the sealing sheet; and / or the rotary seal also includes a fastener penetrating the supporting rotary disk, the sealing sheet and the annular pressure plate. Before the rotary seal is fixed, the positioning column can be used to first realize the positioning of the supporting rotary disk, the annular pressure plate and the sealing sheet to simplify the subsequent fixing operation.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0056] The present application provides a cover assembly, Figures 1 to 16 A structural schematic diagram of a first embodiment of a cover assembly according to the utility model is shown. The first embodiment of the cover assembly of the present application is described below in conjunction with the accompanying drawings.

[0057] like Figures 1 to 5 As shown, the first embodiment of the cover assembly includes: an upper cover 10, a steel cover 20, an exhaust structure 30 and a rotating seal 40. The upper cover 10 has a steam port 101; the steel cover 20 is rotatably arranged below the upper cover 10 and has a cover-closing position and a cover-opening position; the exhaust structure 30 is arranged on the steel cover 20; the rotating seal 40 is arranged between the upper cover 10 and the steel cover 20 and can rotate synchronously with the steel cover 20, the rotating seal 40 has a first sealing position corresponding to the cover-closing position and a second sealing position corresponding to the cover-opening position, the rotating seal 40 has an exhaust area 401 corresponding to the steam port 101, the exhaust structure 30 is sealingly penetrated through the rotating seal 40 and is located in the exhaust area 401, wherein, when the rotating seal 40 is located at the first sealing position and the second sealing position, the top of the rotating seal 40 is sealed with the upper cover 10 to seal the exhaust area 401.

[0058] By applying the technical solution of this embodiment, the cover assembly includes a rotating seal 40 arranged between the upper cover 10 and the steel cover 20. The rotating seal 40 can be sealed with the exhaust structure 30 and the upper cover 10 arranged on the steel cover 20, thereby preventing the steam generated during the exhaust process from entering between the upper cover 10 and the steel cover 20, and the rotating seal 40 can rotate synchronously with the steel cover 20, so that the exhaust structure 30 can also be set as a rotating structure, that is, the steel cover 20, the exhaust structure 30 and the rotating seal 40 can rotate synchronously, so that there is no need to set the steel cover as a split structure as in the related art, and the steel cover 20 can be directly set as an integrated structure, which simplifies the structure of the steel cover 20 while ensuring the sealing effect between the exhaust structure 30 and the upper cover 10, and reduces the complexity and cost of the steel cover 20. Therefore, the technical solution of this embodiment can effectively solve the problem of complex structure and high cost of the steel cover in the related art.

[0059] Specifically, when the steel cover 20 is in the closing position and the rotating seal 40 is in the first sealing position, a large amount of steam will be generated during the cooking process. After the steam contacts the rotating seal 40 and the upper cover, condensed water will be formed. At this time, the rotating seal 40 is sealed with the upper cover 10 to prevent steam and condensed water from entering between the upper cover 10 and the steel cover 20. When the steel cover 20 is in the opening position and the rotating seal 40 is in the second sealing position, the user can flip the cover assembly to open the cover. At this time, the rotating seal 40 is sealed with the upper cover 10 to prevent condensed water accumulated during the cooking process from flowing between the steel cover 20 and the upper cover 10 as the user flips the cover assembly.

[0060] When the rotating seal 40 switches between the first sealing position and the second sealing position, the rotating seal 40 can be sealed with the upper cover 10 to ensure the sealing effect; of course, the rotating seal 40 may not be sealed with the upper cover 10, which can reduce the operating resistance when the user drives the steel cover 20 to rotate, and the hand feel is better.

[0061] It should be noted that the exhaust area 401 refers to the area inside the sealing cooperation position of the rotating seal 40 and the upper cover 10. The above-mentioned "the top of the rotating seal 40 is sealed with the upper cover 10 to seal the exhaust area 401" means that the exhaust area 401 is connected to the outside of the cover body assembly only through the steam port 101, but is not connected to the area between the upper cover 10 and the steel cover 20.

[0062] like Figure 1 , Figure 8 and Fig.12As shown, the cover assembly further includes a mounting seat 50, which is disposed between the upper cover 10 and the steel cover 20 and supported below the rotating seal 40. The mounting seat 50 is supported below the rotating seal 40 and, together with the upper cover 10, limits the rotating seal 40 in the up and down directions, so that the rotating seal 40 can only move in the lateral direction to rotate synchronously with the steel cover 20.

[0063] like Figure 1 and Figure 8 As shown, the upper cover 10 includes a surface cover 11 and a lining cover 12, the lining cover 12 is arranged between the surface cover 11 and the steel cover 20, the top of the rotating seal 40 is sealed with the surface cover 11, and the mounting seat 50 is located between the lining cover 12 and the surface cover 11 and connected to the lining cover 12 and / or the surface cover 11. The mounting seat 50 is connected to the lining cover 12 and / or the surface cover 11, so that the position of the mounting seat 50 and the upper cover 10 can be relatively fixed, and then the rotating seal 40 will not change its position in the up and down direction with the pressure increase or decrease in the cooking cavity, thereby ensuring the sealing effect between the rotating seal 40 and the upper cover 10.

[0064] like Figure 1 As shown, a first avoidance opening 121 for avoiding the exhaust structure 30 is provided on the liner cover 12 .

[0065] It should be noted that the above-mentioned “the mounting seat 50 is connected to the lining cover 12 and / or the surface cover 11” means that the mounting seat 50 and the lining cover 12 and / or the surface cover 11 are an integrally formed structure, or the mounting seat 50 is an independently arranged structure and is connected to the lining cover 12 and / or the surface cover 11 through a connecting member.

[0066] In addition, by applying the technical solution of this embodiment, the exhaust structure 30 and the steam cover 14 can be set away from the center of the cover body assembly. In this way, part of the space above the surface cover 11 close to the user can be left empty for setting structures such as the control panel, without having to set the control panel on the side of the cooking appliance, thereby facilitating user use.

[0067] like Figure 1 and Fig.11 As shown, in the present embodiment, the cover assembly further includes a steam cover 14, and a mounting port 111 is provided on the face cover 11. The steam cover 14 is detachably provided at the mounting port 111 and is capable of covering the mounting port 111. The steam port 101 is formed on the steam cover 14 or between the steam cover 14 and the face cover 11. The steam cover 14 is capable of covering the rotating seal 40 and the exhaust structure 30 to ensure the aesthetics of the cover assembly. During the exhaust process, part of the steam discharged through the upper end of the exhaust structure 30 is condensed in the exhaust area 401 to form condensed water, and part of the steam is discharged from the steam port 101 to the external space.

[0068] In the present application, a rotating structure (i.e., a rotating seal 40) is disposed between the face cover 11 and the steel cover 20, and a steam cover 14 is disposed above the rotating structure to shield it. The steam cover 14 does not need to rotate synchronously with the steel cover 20 and the rotating seal 40, so that the appearance above the cover assembly is consistent, thereby improving the user experience.

[0069] Of course, in an embodiment not shown in the figure, the steam cover may not be provided and the steam port may be directly provided on the surface cover.

[0070] like Fig.12 and Fig.13 As shown, the mounting seat 50 includes a support plate 51 and a connecting arm 52 disposed outside the support plate 51. The support plate 51 is provided with a supporting protrusion 511 that supports the bottom of the rotating seal 40. In this embodiment, the mounting seat 50 is connected to the cover 11 by screws passing through the connecting arm 52 and the cover 11. The supporting protrusion 511 is provided on the support plate 51, which can reduce the supporting area between the support plate 51 and the rotating seal 40, thereby reducing the rotation resistance of the rotating seal 40, so that the user can drive the steel cover 20 and the rotating seal 40 to rotate. The operation feel is better. Fig.12 As shown, a second avoidance opening 53 for avoiding the exhaust structure 30 is provided on the support plate 51 .

[0071] like Fig.12 and Fig.13 As shown, the support protrusion 511 includes an elastic convex point, and the elastic convex point applies a resisting force toward the face cover 11 to the rotating seal 40. The elastic convex point has a certain floating ability in the up and down direction. When the face cover 11 or the rotating seal 40 itself has a certain processing or installation error, the floating ability of the elastic convex point can compensate for these errors, thereby ensuring the sealing effect between the rotating seal 40 and the face cover 11.

[0072] like Fig.12 and Fig.13 As shown, a mounting tube 54 is provided on the support plate 51, and the elastic protrusion includes a push rod 5111 movably arranged in the mounting tube 54 and an elastic member 5112 arranged between the push rod 5111 and the bottom wall of the mounting tube 54, the upper end of the push rod 5111 extends out of the mounting tube and is provided with an arc-shaped push surface, the arc-shaped push surface cooperates with the lower surface of the supporting turntable 41 and pushes upward against the rotating seal 40 to press the rotating seal 40 under the surface cover 11, thereby ensuring the sealing effect between the rotating seal 40 and the surface cover 11.

[0073] Correspondingly, a slide 417 is arranged on the lower surface of the supporting turntable 41, and the bottom wall of the slide 417 has a first mating surface 4171, a second mating surface 4172 and a third mating surface 4173 arranged in sequence, wherein the second mating surface 4172 protrudes upward from the first mating surface 4171 and the third mating surface 4173. During the process of switching the rotating seal 40 from the first sealing position to the second sealing position, the push rod 5111 is sequentially abutted against the first mating surface 4171, the second mating surface 4172 and the third mating surface 4173. This arrangement enables the push rod 5111 to apply a large push force to the rotating seal 40 when the steel cover 20 is in the open cover position and the closed cover position, thereby ensuring the sealing effect between the rotating seal 40 and the upper cover 10; when the steel cover 20 is in a position between the open cover position and the closed cover position, the push rod 5111 applies a small push force to the rotating seal 40, thereby reducing the resistance when the user drives the steel cover 20 and the rotating seal 40 to rotate, thereby improving the smoothness of the user's operation.

[0074] like Figures 4 to 10 as well as Fig.14 As shown, the rotary seal 40 includes a supporting turntable 41 and a sealing sheet 42 disposed on the supporting turntable 41. The sealing sheet 42 has a top sealing surface 402. The upper cover 10 is provided with an annular sealing rib 13. The top sealing surface 402 abuts against the annular sealing rib 13. The sealing sheet 42 itself is a flexible structure, which can maintain a good sealing effect with the annular sealing rib 13 on the upper cover 10. The sealing sheet 42 is supported by the supporting turntable 41, which facilitates the installation of the rotary seal 40. The provision of the annular sealing rib 13 can reduce the matching area between the top sealing surface 402 and the upper cover 10, reduce the rotation resistance, and thus make the user's operation feel better.

[0075] like Fig. 9 and Fig.10 As shown, the annular sealing rib 13 includes a first annular retaining rib 131 and a second annular retaining rib 132. When the rotary seal 40 is located at the first sealing position, the first annular retaining rib 131 abuts against the top sealing surface 402. When the rotary seal 40 is located at the second sealing position, the second annular retaining rib 132 abuts against the top sealing surface 402. By providing the first annular retaining rib 131 and the second annular retaining rib 132, the sealing effect between the rotary seal 40 and the upper cover 10 can be ensured at the first sealing position and the second sealing position.

[0076] like Fig. 9 and Fig.10As shown, the annular sealing rib 13 includes a first rib body 133, a second rib body 134 and a third rib body 135. The first rib body 133 and the second rib body 134 are arranged to form a first annular retaining rib 131. The third rib body 135 is located outside the second rib body 134 and is arranged to form a second annular retaining rib 132 with the first rib body 133. That is, the first annular retaining rib 131 and the second annular retaining rib 132 share the first rib body 133, so that the structure of the annular sealing rib 13 is simple.

[0077] Specifically, the rotating seal 40 rotates from the first sealing position to the second sealing position along the direction from the first rib 133 to the third rib 135 , that is, the third rib 135 is arranged on one side of the rotating direction of the rotating seal 40 .

[0078] Correspondingly, in order to reduce the space occupied by the rotating seal 40 inside the cover body assembly and leave space for setting up other structures, the top sealing surface 402 cooperating with the first rib 133 can be set to be wider, and the top sealing surface 402 cooperating with the second rib 134 and the third rib 135 can be set to be narrower. Specifically, the top sealing surface 402 includes a first sealing area and a second sealing area, the width of the first sealing area is smaller than the width of the second sealing area, the first sealing area is set corresponding to the second rib 134 and the third rib 135, and the second sealing area is set corresponding to the first rib 133.

[0079] Since the top sealing surface 402 abuts against the annular sealing rib 13 , the top sealing surface 402 may be worn. In order to reduce the wear on the top sealing surface 402 , the top sealing surface 402 may be polished and / or oil-sprayed to extend the service life of the rotating seal 40 .

[0080] Specifically, in this embodiment, the first annular retaining rib 131 and the second annular retaining rib 132 are both interference fit with the top sealing surface 402, and the interference is between 0.3 mm and 1 mm. By making the first annular retaining rib 131 and the second annular retaining rib 132 both interference fit with the top sealing surface 402, the sealing effect is ensured. Preferably, the interference between the first annular retaining rib 131 and the top sealing surface 402 can be 0.3 mm, 0.5 mm, 0.8 mm or 1 mm; the interference between the second annular retaining rib 132 and the top sealing surface 402 can be 0.3 mm, 0.5 mm, 0.8 mm or 1 mm.

[0081] like Figures 3 to 7As shown, the sealing sheet 42 includes a sealing convex ring 421, and the top sealing surface 402 is formed on the sealing convex ring 421, and the sealing convex ring 421 is spaced apart from the supporting rotating disk 41. The sealing convex ring 421 is spaced apart from the supporting rotating disk 41, so that the sealing convex ring 421 has a certain ability to deform downward, and can compensate for the processing and installation errors of the upper cover 10 and the rotating seal 40, thereby ensuring the sealing effect between the rotating seal 40 and the upper cover 10.

[0082] Furthermore, in order to ensure the elastic deformation ability and structural strength of the sealing convex ring 421 so that the sealing convex ring 421 can always be sealed with the upper cover 10, a support rib that cooperates with the support turntable 41 can be provided below the sealing convex ring.

[0083] like Figures 3 to 7 As shown, the support turntable 41 is provided with a support rib 411, which extends below the sealing rib 421. The support rib 411 can position the sealing rib 421 in the transverse direction, so that the sealing rib 421 remains in a position to abut against the annular sealing rib 13.

[0084] Specifically, there may be multiple (two or more) supporting ribs 411, and multiple supporting ribs 411 are nested. Since the sealing convex ring 421 has a certain width, the supporting ribs 411 also need to cover a sufficient area to ensure the positioning effect of the sealing convex ring 421. By providing multiple supporting ribs 411, the positioning effect of the sealing convex ring 421 can be ensured, and at the same time, it is also possible to avoid the shrinkage phenomenon caused by the excessive width of a single supporting rib 411 during the processing. Fig.14 As shown, in this embodiment, two supporting ribs 411 are provided, and a multi-connecting rib 414 is provided between the two supporting ribs 411 .

[0085] Among them, Figure 7 As shown, the thickness T1 of the sealing convex ring 421 is between 1.5 mm and 3.5 mm; within this range, the thickness T1 can take into account both the deformation ability and the structural strength of the sealing convex ring 421, so that the sealing convex ring 421 can always be sealed with the annular sealing convex rib 13. In addition, since the sealing convex ring 421 will move relative to the annular sealing convex rib 13, the sealing convex ring 421 will produce a certain degree of wear, and setting the sealing convex ring 421 to be thicker can ensure the service life of the rotating seal 40. Preferably, the thickness T1 of the sealing convex ring 421 can be 1.5 mm, 2 mm, 2.5 mm, 3 mm or 3.5 mm.

[0086] like Figure 7As shown, the distance D between the lower surface of the sealing convex ring 421 and the upper surface of the supporting convex rib 411 is between 0.5 mm and 2.5 mm. Within this range, the distance D can take into account both the deformation ability and the structural strength of the sealing convex ring 421, so that the sealing convex ring 421 can always be sealed with the annular sealing convex rib 13. Preferably, the distance D can be 0.5 mm, 1 mm, 1.5 mm, 2 mm or 2.5 mm.

[0087] like Figures 3 to 7 as well as Fig.14 As shown, the sealing sheet 42 has a water collecting recess 423 located inside the sealing convex ring 421, and the exhaust structure 30 is disposed through the water collecting recess 423. The water collecting recess 423 is recessed relative to the top sealing surface 402, so that condensed water and food residues and other dirt generated during cooking will be collected in the water collecting recess 423, preventing condensed water and food residues and other dirt from remaining on the top sealing surface 402 and leaking between the upper cover 10 and the steel cover 20 or affecting the rotation of the rotating seal 40 relative to the annular sealing rib 13.

[0088] Specifically, the sinking depth of the water collecting recess 423 relative to the top sealing surface 402 is greater than or equal to 5 mm, so that the water collecting recess 423 has a sufficiently large water storage space.

[0089] like Figure 1 as well as Figures 3 to 7 As shown, the exhaust structure 30 includes an exhaust pipe 31 penetrating the steel cover 20 and the bottom wall of the water collecting recess 423, and a pressure limiting valve 32 arranged above the exhaust pipe 31, and the pressure limiting valve is located in the water collecting recess 423. When cooking, when the pressure inside the cooking cavity is increased or decreased, the steel cover 20 will float up and down, thereby driving the exhaust structure 30 to float up and down. Since the sealing sheet 42 is a flexible structure, the bottom of the water collecting recess 423 can be deformed to adapt to the up and down floating of the exhaust structure 30, thereby avoiding the rotating seal 40 being set as a structure that can float up and down.

[0090] Specifically, in the present embodiment, the user can drive the steel cover 20 to rotate by operating the operating member. The exhaust pipe 31 is fixedly disposed on the steel cover 20 . When the steel cover 20 rotates, the rotating seal 40 is driven to rotate through the exhaust pipe 31 .

[0091] like Figure 5 as well as Fig.14As shown, the water collecting recess 423 has a first water receiving surface 4231, a second water receiving surface 4232 and a connecting wall 4233, wherein the first water receiving surface 4231 is an annular structure, the second water receiving surface 4232 is arranged in the middle of the annular structure and is lower than the first water receiving surface 4231, and the first water receiving surface 4231 and the second water receiving surface 4232 are connected by the connecting wall 4233. The cover assembly also includes a cold air exhaust structure 61 penetrating the steel cover 20 and a push rod 62 sealingly penetrating the first water receiving surface 4231, and the push rod 62 is located above the cold air exhaust structure 61. Specifically, before the pressure inside the cooking utensil is increased, the cold air in the cooking cavity can be discharged through the cold air exhaust structure 61. When the pressure in the cooking cavity rises to a certain level, the cold air exhaust structure 61 floats up under the pressure in the cooking cavity. After the cooking is finished and the pressure in the cooking cavity drops, the cold air exhaust structure 61 generally falls down under the action of its own gravity. However, in actual use, the cold air exhaust structure 61 is often difficult to fall down, thereby hindering the steel cover 20 from rotating to the cover opening position. A push rod 62 is provided on the first water receiving surface 4231. The user can press the push rod 62 downward so that the push rod 62 presses down the cold air exhaust structure 61 to smoothly open the cover. A avoidance portion 415 is provided on the support turntable 41 at a position corresponding to the push rod 62. The push rod 62 is inserted into the avoidance portion 415. The avoidance portion 415 can be a concave structure or a avoidance opening structure, so that the push rod 62 and the first water receiving surface 4231 connected to the push rod 62 can have a certain downward movement ability.

[0092] A second water receiving surface 4232 is set lower than the first water receiving surface 4231, so that condensed water, food residues and other dirt are first gathered in the space formed by the second water receiving surface 4232 and the connecting wall 4233, avoiding condensed water, food residues and other dirt from remaining above the push rod 62 and affecting the user experience.

[0093] The exhaust pipe 31 of the exhaust structure 30 is penetrated through the second water receiving surface 4232 , and the pressure limiting valve 32 is located above the second water receiving surface 4232 , so that the structure above the exhaust structure 30 can be sunk into the range of the rotating seal 40 as much as possible to avoid protruding upward from the surface cover 11 .

[0094] Specifically, in this embodiment, the shape of the water collecting recess 423 (specifically, the outer contour shape of the first water receiving surface 4231) is adapted to the shape of the mounting opening 111 provided on the face cover 11, and the shape of the annular sealing rib 13 (specifically, the first annular retaining rib 131) is adapted to the shape of the mounting opening 111. When the steel cover 20 is located in the closed position and the rotating seal 40 is located in the first sealing position ( Figure 2The water collecting recess 423 is directly opposite to the installation opening 111, so that the area of ​​the top sealing surface 402 located inside the annular sealing rib 13 is small, thereby preventing condensed water and food residues from remaining on the top sealing surface 402. Figure 3 In the position shown in FIG. 1 , the water collecting recess 423 is offset from the mounting opening 111 , and a portion of the top sealing surface 402 is exposed at the mounting opening 111 .

[0095] like Figure 7 As shown, the thickness T2 of the bottom wall of the water collecting recess 423 (in this embodiment, specifically the thickness of the second water receiving surface 4232) is between 0.3 mm and 1 mm, so that the bottom wall of the water collecting recess 423 has a large deformation capacity to adapt to the up and down floating of the exhaust structure 30. Preferably, the thickness T2 of the bottom wall of the water collecting recess 423 can be 0.3 mm, 0.5 mm, 0.8 mm or 1 mm.

[0096] like Figure 7 As shown, the thickness T3 of the side wall of the water collecting recess 423 (in this embodiment, specifically the thickness of the connecting wall 4233) is between 0.5 mm and 2 mm; a large amount of steam may be generated during cooking, resulting in a large amount of condensed water. The user may clean the condensed water and food residues collected in the water collecting recess 423 by himself, so that the thickness T3 of the side wall of the water collecting recess 423 is within the above range, so that the side wall of the water collecting recess 423 has a certain strength, and the user is prevented from taking the water collecting recess 423 out when cleaning. Preferably, the thickness T3 of the side wall of the water collecting recess 423 may be 0.5 mm, 1 mm, 1.5 mm or 2 mm.

[0097] like Figure 1 and Fig.14 As shown, the rotary seal 40 includes a supporting turntable 41, an annular pressure plate 43 and a sealing sheet 42. The supporting turntable 41 is supported below the sealing sheet 42, and the sealing sheet 42 is sandwiched between the annular pressure plate 43 and the supporting turntable 41. The supporting turntable 41 and the annular pressure plate 43 are hard structures, and the sealing sheet 42 is a flexible structure (specifically, it can be made of a material with elastic deformation ability such as rubber or silicone). The sealing sheet 42 is clamped by the supporting turntable 41 and the annular pressure plate 43 to achieve positioning and fixing of the sealing sheet 42, so that the overall structure of the rotary seal 40 is stable, which is convenient for installation and positioning of the rotary seal 40.

[0098] In this embodiment, the annular pressure plate 43, the sealing sheet 42 and the supporting turntable 41 are arranged in sequence from top to bottom. Of course, in an embodiment not shown in the figure, the annular pressure plate can also be arranged below the supporting turntable. Specifically, a slot structure with an inward opening can be arranged at the lower end of the sealing sheet, so that the outer edge of the supporting turntable is inserted into the slot structure, and the lower wall of the slot structure is pressed onto the supporting turntable by the annular pressure plate arranged below the supporting turntable, so as to fix the sealing sheet.

[0099] like Fig.14 and Fig.15 As shown, the rotating seal 40 also includes a positioning column 44 arranged between the supporting turntable 41, the annular pressure plate 43 and the sealing sheet 42. Before fixing the rotating seal 40, the positioning column 44 can be used to first realize the positioning of the supporting turntable 41, the annular pressure plate 43 and the sealing sheet 42 to simplify the subsequent fixing operation.

[0100] Specifically, Fig.14 and Fig.15 As shown, the sealing sheet 42 also includes a connecting edge 426 arranged on the outer periphery of the sealing convex ring 421, the connecting edge 426 is clamped between the annular pressure plate 43 and the supporting turntable 41, the positioning column 44 is arranged on the lower surface of the annular pressure plate 43, the connecting edge 426 is provided with a first connecting hole 4261, and the supporting turntable 41 is provided with a second connecting hole 416, the positioning column 44 passes through the first connecting hole 4261 and the second connecting hole 416 in sequence to position the supporting turntable 41, the annular pressure plate 43 and the sealing sheet 42.

[0101] like Fig.14 and Fig.15 As shown, the rotary seal 40 further includes a fastener 45 penetrating the support rotary disc 41, the sealing sheet 42 and the annular pressure plate 43. The fastener 45 fixes the support rotary disc 41, the annular pressure plate 43 and the sealing sheet 42 to ensure the stability of the overall structure of the rotary seal 40.

[0102] Figures 17 to 22 A structural schematic diagram of a second embodiment of a cover assembly according to the utility model is shown. The parts of the second embodiment of the cover assembly of the present application that are different from the first embodiment are described below in conjunction with the accompanying drawings, and the same contents in the two embodiments are not repeated here.

[0103] Specifically, the structural composition of the rotating seal 40 and the structural details of the mounting seat 50 in this embodiment are different from those in the first embodiment. In the first embodiment, the rotating seal 40 is a three-layer structure; in this embodiment, the rotating seal 40 is a two-layer structure.

[0104] like Fig.17 , Fig.18 , Fig. 20 and Fig.21As shown, the rotary seal 40 includes a support turntable 41 and a sealing sheet 42 disposed on the support turntable 41, the support turntable 41 is provided with a mounting hole 413, a connecting column 424 penetrating the mounting hole 413 is disposed below the sealing sheet 42, and a stopper 425 is disposed at the lower end of the connecting column 424 to cooperate with the lower surface stopper of the support turntable 41. Specifically, by arranging the connecting column 424 and the stopper 425 below the sealing sheet 42 to achieve connection with the support turntable 41, fasteners such as screws can be omitted, and the structure of the rotary seal 40 is simplified.

[0105] like Fig.21 and Fig. 22 As shown, in the direction from top to bottom, the cross-sectional size of the stopper 425 gradually decreases, and the size of the upper end surface of the stopper 425 is larger than the size of the mounting hole 413. When the sealing sheet 42 and the supporting turntable 41 are assembled, the lower end of the stopper 425 is aligned with the mounting hole 413, and the stopper 425 is squeezed and deformed to pass through the mounting hole 413 and then cooperates with the stopper on the lower surface of the supporting turntable 41.

[0106] The setting of the stopper 425 prevents the sealing sheet 42 from being brought out when the user cleans the condensed water and dirt inside the rotating seal 40 .

[0107] like Fig. 20 and Fig.21 As shown, the sealing sheet 42 includes a sealing convex ring 421, a top sealing surface 402 is formed on the sealing convex ring 421, and the sealing convex ring 421 is spaced apart from the supporting rotating disk 41. The sealing sheet 42 also includes a supporting rib 422 disposed below the sealing convex ring 421 and abutting against the supporting rotating disk 41. The sealing convex ring 421 suspended relative to the supporting rotating disk 41 is supported by the supporting rib 422, so that the deformation ability and structural strength of the sealing convex ring 421 can be taken into account.

[0108] like Fig.18 , Fig. 20 and Fig.21 As shown, the sealing sheet 42 has a water collecting recess 423 located inside the sealing convex ring 421, and the exhaust structure 30 is arranged in the water collecting recess 423. The side wall of the water collecting recess 423 protrudes downward from the bottom wall of the water collecting recess 423, and the supporting turntable 41 is provided with a mounting recess 412, and the lower end of the side wall of the water collecting recess 423 extends into the mounting recess 412. A large amount of steam is generated during the cooking process, which leads to a large amount of condensed water. The user can clean the condensed water and food residues collected in the water collecting recess 423 by himself, so that the side wall of the water collecting recess 423 protrudes downward and is inserted into the mounting recess 412 on the supporting turntable 41, which can prevent the water collecting recess 423 from detaching upward from the supporting turntable 41 when the user cleans it, that is, it can prevent the water collecting recess 423 from being taken out when the user cleans it.

[0109] In this embodiment, an annular sealing rib is arranged below the face cover 11, and the annular sealing rib includes a first rib body, a second rib body and a third rib body. The first rib body and the second rib body are arranged to form a first annular retaining rib, and the third rib body is located on the outside of the second rib body and is arranged to form a second annular retaining rib with the first rib body.

[0110] Correspondingly, in order to reduce the space occupied by the rotating seal 40 inside the cover body assembly and leave space for setting up other structures, the top sealing surface 402 that cooperates with the first rib body can be set to be wider, and the top sealing surface 402 that cooperates with the second rib body and the third rib body can be set to be narrower. Specifically, the top sealing surface 402 includes a first sealing area 4021 and a second sealing area 4022. The width of the first sealing area 4021 is smaller than the width of the second sealing area 4022. The first sealing area 4021 is set corresponding to the second rib body and the third rib body, and the second sealing area 4022 is set corresponding to the first rib body.

[0111] like Fig. 22 As shown, in this embodiment, a support protrusion 511 is provided on the support plate 51 of the mounting seat 50. The support protrusion 511 is a support rib structure. The rotating seal 40 is supported by the support rib structure, which can reduce the rotation resistance between the two.

[0112] The present application also provides a cooking utensil, comprising a cover assembly, wherein the cover assembly is the above-mentioned cover assembly, which can effectively solve the problem of complex steel cover structure and high cost in related technologies, and the cooking utensil with the above-mentioned cover assembly also has the above-mentioned advantages.

[0113] Specifically, in the present embodiment, the cooking utensil is a pressure cooking utensil. Of course, in embodiments not shown in the figure, the cooking utensil can also be products such as an electric rice cooker, a low-pressure rice cooker, a soybean milk machine, a food processor, a cooking machine, an electric stew pot, a multi-function pot, etc.

[0114] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

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

[0116] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0117] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
