Description

Technical Field

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

[0002] In the related art, the pressure limiting valve on the pressure cooking appliance is arranged deviating from the center of the cover body assembly, so that more space can be left on the upper surface of the cover body assembly for installing the operation panel, thereby facilitating the user to operate the operation panel.

[0003] Since the pressure limiting valve needs to rotate synchronously with the inner cover, after the pressure limiting valve is arranged deviating from the center of the cover body assembly, the pressure limiting valve will rotate relative to the upper cover. Since steam is discharged at the pressure limiting valve, the discharged steam becomes condensed water after encountering the cover body assembly, and the condensed water easily flows into the space between the upper cover and the inner cover from the gap between the pressure limiting valve installation structure and the upper cover. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a cover body assembly and a cooking appliance having the same, so as to solve the problem that the condensed water in the related art easily flows into the space between the upper cover and the inner cover.

[0005] To achieve the above purpose, according to one aspect of the utility model, a cover body 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 and corresponding to the exhaust port; a sealing turntable arranged between the upper cover and the inner cover and capable of rotating synchronously with the inner cover, the sealing turntable including a sealing piece, the exhaust structure passing through the sealing piece, the sealing piece including a sealing ring body and a concave water collecting part arranged inside the sealing ring body, the sealing ring body being in sealing cooperation with the upper cover, and the concave water collecting part being in sealing cooperation with the exhaust structure.

[0006] Applying the technical solution of the utility model, a sealing turntable is arranged between the inner cover and the upper cover, the sealing turntable can rotate synchronously with the inner cover, the sealing piece of the sealing turntable includes a sealing ring body and a concave water collecting part arranged inside the sealing ring body, wherein, the sealing ring body is in sealing cooperation with the upper cover, and the concave water collecting part is in sealing cooperation with the exhaust structure. The steam discharged through the exhaust structure becomes condensed water after encountering the sealing piece and the upper cover, and the condensed water will be stored in the concave water collecting part. Since the sealing ring body is in sealing cooperation with the upper cover, the steam and the condensed water will not enter the space between the upper cover and the inner cover. Therefore, the technical solution of the present application can effectively solve the problem that the condensed water in the related art easily flows into the space between the upper cover and the inner cover.

[0007] Furthermore, the distance between the upper surface of the sealing ring body and the upper surface of the concave water collecting part is between 2 mm and 10 mm. Such a setting enables the concave water collecting part to have a larger space for storing water.

[0008] Further, the concave water collecting part includes a first concave surface and a second concave surface located in the middle of the first concave surface. The second concave surface is lower than the first concave surface. The inner cover further includes a cold air exhausting structure provided on the cover body. The cover assembly further includes a push rod passing through the first concave surface and correspondingly arranged with the cold air exhausting structure. The push rod is in sealing cooperation with the first concave surface. By providing the push rod, the user can press down the push rod to make the cold air exhausting structure drop to open the cover smoothly. The push rod is arranged on the relatively high first concave surface, so that the condensed water and food residues generated during the cooking process will be stored at the second concave surface first, avoiding the food residues staying at the push rod and being difficult to clean.

[0009] Further, the exhaust structure includes an exhaust pipe passing through the second concave surface and a pressure limiting valve arranged above the exhaust pipe. By arranging the pressure limiting valve above the second concave surface, the pressure limiting valve can be prevented from protruding above the upper cover or the height of the pressure limiting valve protruding above the upper cover can be reduced, thereby making the upper cover more beautiful.

[0010] Further, the concave water collecting part further includes a connecting wall connecting the first concave surface and the second concave surface, and the thickness of the connecting wall is between 0.5 mm and 2 mm; and / or, the thickness of the first concave surface is between 0.5 mm and 2 mm; and / or, the thickness of the second concave surface is between 0.3 mm and 1 mm. Making the wall thickness of the connecting wall between 0.5 mm and 2 mm can prevent the user from taking out the sealing piece during the cleaning process; making the thickness of the first concave surface between 0.5 mm and 2 mm enables the first concave surface to have a certain ability to move up and down to facilitate the user to operate the push rod; making the thickness of the second concave surface between 0.3 mm and 1 mm enables the second concave surface to have a certain ability to move up and down to adapt to the up and down movement of the exhaust structure.

[0011] Further, the sealing turntable further includes a supporting turntable supported below the sealing piece and a pressing plate arranged above the sealing piece. The sealing piece further includes a connecting edge arranged outside the sealing ring body, and the connecting edge is clamped between the pressing plate and the supporting turntable. By supporting the sealing piece through the supporting turntable, it is convenient to install the sealing turntable. Fixing the sealing piece on the supporting turntable through the pressing plate has the advantages of simple structure and reliable connection.

[0012] Further, the sealing turntable further includes a supporting turntable supported below the sealing piece. The push rod passes through the supporting turntable, and the supporting turntable is provided with an avoidance part corresponding to the push rod to enable the push rod and the first concave surface to move down. The avoidance part can avoid the downward movement of the first concave surface to facilitate the user to operate the push rod.

[0013] Further, the sealing turntable further includes a supporting turntable, which includes a supporting ring plate, a sunken supporting plate arranged inside the supporting ring plate, and an annular supporting rib arranged on the supporting ring plate. The supporting ring plate is supported below the first concave surface, the sunken supporting plate is supported below the second concave surface, and the annular supporting rib is located below the sealing ring body. By arranging the sunken supporting plate and the annular supporting rib on the supporting ring plate, the supporting turntable also forms a three-level height structure adapted to the sealing piece, ensuring the supporting effect on the sealing piece, and at the same time being able to position the sealing ring body, thereby ensuring the sealing effect between the sealing turntable and the upper cover.

[0014] Further, the upper cover includes a face cover and a sealing rib arranged below the face cover. The sealing rib is in abutting cooperation with the sealing ring body. There is a deformation interval between the lower surface of the sealing ring body and the upper surface of the annular supporting rib, and the deformation interval is between 0.5 mm and 2.5 mm; and / or, the thickness of the sealing ring body is between 1.5 mm and 3.5 mm. Such an arrangement enables the sealing ring body to have a certain deformation ability and sufficient structural strength, can compensate for the processing and assembly errors of the sealing rib and the sealing turntable, and enables the sealing ring body to always be in abutting cooperation with the sealing rib, ensuring the sealing effect.

[0015] Further, the cover assembly further includes a mounting seat connected below the upper cover. The sealing turntable is clamped between the mounting seat and the upper cover and can move relative to the mounting seat and the upper cover; and / or, the inner cover has a closed cover position and an open cover position. When the inner cover is in the closed cover position, the sealing turntable is in the first position. When the inner cover is in the open cover position, the sealing turntable is in the second position. When the sealing turntable is in the first position and the second position, the sealing ring body is in sealing cooperation with the upper cover. The mounting seat and the upper cover together limit the sealing turntable in the up and down directions, so that the sealing turntable can only move in the transverse direction to rotate synchronously with the inner cover, ensuring the reliability of the sealing. When the sealing turntable is in the first position and the second position, the sealing ring body is in sealing cooperation with the upper cover, which can prevent condensed water from flowing between the upper cover and the inner cover during the cooking process and when the user flips and opens the cover.

[0016] According to another aspect of the present invention, there is provided a cooking appliance, including a cover assembly, wherein the cover assembly is the above-mentioned cover assembly. The above-mentioned cover assembly can effectively solve the problem that condensed water in the related art easily flows into the space between the upper cover and the inner cover, and the cooking appliance having the above-mentioned cover assembly also has the above-mentioned advantages.

[0036] Such as Figures 1 to 4 And Figure 7As shown in the figure, the present application provides a cover assembly. Embodiments of the cover assembly of the present application include: an upper cover 10, an inner cover 20, and a sealing turntable 30. Among them, the upper cover 10 has an exhaust port 11; the inner cover 20 is rotatably arranged below the upper cover 10. The inner cover 20 includes a cover body 21 and an exhaust structure 22 arranged on the cover body 21 and corresponding to the exhaust port 11; 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 sealing turntable 30 includes a sealing piece 31. The exhaust structure 22 passes through the sealing piece 31. The sealing piece 31 includes a sealing ring body 311 and a concave water collecting part 312 arranged on the inner side of the sealing ring body 311. The sealing ring body 311 is in sealing cooperation with the upper cover 10, and the concave water collecting part 312 is in sealing cooperation with the exhaust structure 22.

[0037] Applying the technical solution of this embodiment, a sealing turntable 30 is arranged between the inner cover 20 and the upper cover 10. The sealing turntable 30 can rotate synchronously with the inner cover 20. The sealing piece 31 of the sealing turntable 30 includes a sealing ring body 311 and a concave water collecting part 312 arranged on the inner side of the sealing ring body 311. Among them, the sealing ring body 311 is in sealing cooperation with the upper cover 10, and the concave water collecting part 312 is in sealing cooperation with the exhaust structure 22. The steam discharged through the exhaust structure 22 turns into condensed water after encountering the sealing piece 31 and the upper cover 10. The condensed water will be stored in the concave water collecting part 312. Since the sealing ring body 311 is in sealing cooperation with the upper cover 10, the steam and the condensed water will not enter the space between the upper cover 10 and the inner cover 20. Therefore, the technical solution of this embodiment can effectively solve the problem that the condensed water in the related art easily flows into the space between the upper cover and the inner cover.

[0038] In addition, the setting of the concave water collecting part 312 makes it difficult for the condensed water and dirt such as food residues to remain on the upper surface of the sealing ring body 311, thereby avoiding the influence of the condensed water and dirt such as food residues on the rotation of the sealing turntable 30 and the sealing effect.

[0039] Specifically, in this embodiment, the inner cover 20 has a closed position and an open position. When the inner cover 20 is in the closed position, the sealing turntable 30 is in the first position. When the inner cover 20 is in the open position, the sealing turntable 30 is in the second position. When the sealing turntable 30 is in the first position and the second position, the sealing ring body 311 is in sealing cooperation with the upper cover 10. Among them, when the inner cover 20 is in the closed position and cooking is carried out, a large amount of steam will be generated. At this time, the sealing ring body 311 is in sealing cooperation with the upper cover 10, which can prevent steam and condensed water from entering between the upper cover 10 and the inner cover 20. When the inner cover 20 is in the open position, the user can flip the cover assembly to open the cover. At this time, the sealing ring body 311 is in sealing cooperation with the upper cover 10, which can prevent the condensed water remaining in the lower concave water collecting part 312 from flowing into between the upper cover 10 and the inner cover 20 after cooking. As for the process of the sealing turntable 30 switching between the first position and the second position, the sealing ring body 311 can be in sealing cooperation with the upper cover 10 to further ensure the sealing effect. Of course, the sealing ring body 311 can also not be in sealing cooperation with the upper cover 10, which can make the rotation of the sealing turntable 30 smoother.

[0040] In this embodiment, the distance between the upper surface of the sealing ring body 311 and the upper surface of the lower concave water collecting part 312 is between 2 mm and 10 mm. Such a setting makes the lower concave water collecting part 312 have a relatively large space for storing water. Preferably, the distance between the upper surface of the sealing ring body 311 and the upper surface of the lower concave water collecting part 312 can be 2 mm, 4 mm, 6 mm, 8 mm or 10 mm.

[0041] As Figure 3 、 Figure 4 、 Figure 6 and Figure 7 shown, the lower concave water collecting part 312 includes a first lower concave surface 3121 and a second lower concave surface 3122 located in the middle of the first lower concave surface 3121. The second lower concave surface 3122 is lower than the first lower concave surface 3121. The inner cover 20 further includes an exhaust cold air structure 23 provided on the cover body 21. The cover assembly further includes a push rod 40 passing through the first lower concave surface 3121 and corresponding to the exhaust cold air structure 23. The push rod 40 is in sealing cooperation with the first lower concave surface 3121. The exhaust cold air structure 23 can play a role in exhausting the cold air inside the cooking cavity before pressing and floating up to limit the opening of the cover when pressing. However, after cooking is completed and the pressure inside the cooking cavity drops, the exhaust cold air structure 23 is likely to remain in the floating position, making the cover assembly unable to be opened. By providing the push rod 40, the user can press down the push rod 40 to make the exhaust cold air structure 23 fall to open the cover smoothly. By setting the push rod 40 on the relatively high first lower concave surface 3121, the condensed water and food residues generated during cooking will be stored at the second lower concave surface 3122 first, avoiding food residues remaining at the push rod 40 and being difficult to clean.

[0042] As Figures 1 to 4As shown, the exhaust structure 22 includes an exhaust pipe 221 passing through the second concave surface 3122 and a pressure limiting valve 222 disposed above the exhaust pipe 221. By arranging the pressure limiting valve 222 above the second concave surface 3122, the pressure limiting valve 222 can be prevented from protruding from the upper cover 10 or the height of the pressure limiting valve 222 protruding from the upper cover 10 can be reduced, thereby making the upper cover 10 more aesthetically pleasing.

[0043] As Figure 3 and Figure 7 shown, the concave water collecting part 312 further includes a connecting wall 3123 connecting the first concave surface 3121 and the second concave surface 3122, and the thickness of the connecting wall 3123 is between 0.5 mm and 2 mm. After cooking is completed, the user can remove the pressure limiting valve 222 to clean the condensed water and food residues inside the concave water collecting part 312. Making the wall thickness of the connecting wall 3123 between 0.5 mm and 2 mm can prevent the user from taking out the sealing piece 31 during the cleaning process. Preferably, the thickness of the connecting wall 3123 can be 0.5 mm, 1 mm, 1.5 mm or 2 mm.

[0044] As Figure 3 and Figure 7 shown, the thickness of the first concave surface 3121 is between 0.5 mm and 2 mm; the thickness of the second concave surface 3122 is between 0.3 mm and 1 mm. When using the push rod 40 to push the cold air exhausting structure 23, the push rod 40 needs to move downward. Making the thickness of the first concave surface 3121 between 0.5 mm and 2 mm enables the first concave surface 3121 to have a certain ability to move up and down, facilitating the user to operate the push rod 40. Since the inner cover 20 will float up after being pressed and fall down after the pressure is reduced, the exhaust structure 22 will also move up and down. Making the thickness of the second concave surface 3122 between 0.3 mm and 1 mm enables the second concave surface 3122 to have a certain ability to move up and down to adapt to the up and down movement of the exhaust structure 22, without requiring the entire sealing turntable 30 to move up and down, making the structure simple and ensuring the sealing effect between the sealing turntable 30 and the upper cover 10. Preferably, the thickness of the first concave surface 3121 can be 0.5 mm, 1 mm, 1.5 mm or 2 mm, and the thickness of the second concave surface 3122 can be 0.3 mm, 0.5 mm, 0.8 mm or 1 mm.

[0045] As Figure 1 and Figure 5As shown in the figure, the upper cover 10 includes a face cover 12 and a lining cover 14 disposed below the face cover 12. An installation opening 121 corresponding to the sealing turntable 30 is provided on the face cover 12. A detachable cover 15 is provided at the installation opening 121. The exhaust port 11 is provided on the cover 15. After cooking is completed, the user can remove the cover 15 to clean the condensed water and food residues in the sealing turntable 30, or can operate the push rod 40 through the installation opening 121 to make the cold air exhaust structure 23 that has not successfully fallen down. An avoidance opening 141 capable of avoiding the sealing turntable 30 and the exhaust structure 22 is provided on the lining cover 14 to prevent interference with the rotation of the sealing turntable 30 and the exhaust structure 22.

[0046] Specifically, in this embodiment, when the cover body 21 rotates, it drives the exhaust structure 22 to rotate, and the exhaust structure 22 drives the sealing turntable 30 to rotate, thereby realizing the synchronous rotation of the sealing turntable 30 and the inner cover 20.

[0047] Specifically, in this embodiment, the rotating structure (i.e., the sealing turntable 30) is arranged inside the cover assembly, so that the cover 15 remains stationary relative to the face cover 12 and does not rotate together with the inner cover 20, making the appearance of the cover assembly relatively complete and improving the user experience.

[0048] As Figure 3 、 Figure 4 and Figures 6 to 8 shown, the sealing turntable 30 further includes a support turntable 32 supported below the sealing sheet 31 and a pressing plate 33 disposed above the sealing sheet 31. The sealing sheet 31 further includes a connecting edge 313 disposed outside the sealing ring body 311. The connecting edge 313 is clamped between the pressing plate 33 and the support turntable 32. Since the sealing sheet 31 is a flexible structure (for example: can be made of materials such as silica gel or rubber), by supporting the sealing sheet 31 with the support turntable 32, it is convenient to install the sealing turntable 30. Fixing the sealing sheet 31 on the support turntable 32 through the pressing plate 33 has the advantages of simple structure and reliable connection.

[0049] As Figure 4 、 Figure 6 and Figure 8 shown, the sealing turntable 30 further includes a support turntable 32 supported below the sealing sheet 31. The push rod 40 passes through the support turntable 32. The support turntable 32 is provided with an avoidance portion 324 corresponding to the push rod 40 to enable the push rod 40 and the first concave surface 3121 to move downward. Specifically, in this embodiment, the avoidance portion 324 is a concave portion, which can avoid the downward movement of the first concave surface 3121. Of course, in an embodiment not shown in the figure, the avoidance portion can also be an avoidance opening structure.

[0050] As Figure 3 、 Figure 4 andFigures 6 to 8 As shown in the figure, the sealing turntable 30 further includes a supporting turntable 32. The supporting turntable 32 includes a supporting ring plate 321, a sunken supporting plate 322 arranged inside the supporting ring plate 321, and an annular supporting rib 323 arranged on the supporting ring plate 321. The supporting ring plate 321 is supported below the first concave surface 3121, the sunken supporting plate 322 is supported below the second concave surface 3122, and the annular supporting rib 323 is located below the sealing ring body 311. In this embodiment, the sealing piece 31 has a three-level height structure. By arranging the sunken supporting plate 322 and the annular supporting rib 323 on the supporting ring plate 321, the supporting turntable 32 also forms a three-level height structure adapted to the sealing piece 31, ensuring the supporting effect on the sealing piece 31, and at the same time being able to position the sealing ring body 311, thereby ensuring the sealing effect with the upper cover 10.

[0051] As Figure 3 and Figure 4 shown in the figure, the upper cover 10 includes a face cover 12 and a sealing rib 13 arranged below the face cover 12. The sealing rib 13 is in abutting cooperation with the sealing ring body 311. There is a deformation interval L1 between the lower surface of the sealing ring body 311 and the upper surface of the annular supporting rib 323, and the deformation interval L1 is between 0.5 mm and 2.5 mm; the thickness T1 of the sealing ring body 311 is between 1.5 mm and 3.5 mm. By arranging the sealing rib 13 cooperating with the sealing ring body 311 below the face cover 12, it has the advantages of simple structure and reliable sealing. The setting of the deformation interval L1 enables the sealing ring body 311 to have a certain ability to deform downward, and can compensate for the processing and assembly errors of the sealing rib 13 and the sealing turntable 30, ensuring the sealing effect. The thickness T1 of the sealing ring body 311 is between 1.5 mm and 3.5 mm, enabling the sealing ring body 311 to have a certain deformation ability and sufficient structural strength, so that the sealing ring body 311 can always be in abutting cooperation with the sealing rib 13, further ensuring the sealing effect; in addition, the thickness of the sealing ring body 311 is relatively thick, having a certain wear allowance, thereby ensuring the service life of the sealing turntable 30. Preferably, the deformation interval L1 can be 0.5 mm, 1 mm, 1.5 mm, 2 mm or 2.5 mm, and the thickness T1 can be 1.5 mm, 2 mm, 2.5 mm, 3 mm or 3.5 mm.

[0052] In order to reduce the rotational friction between the sealing ring body 311 and the sealing rib 13 and reduce the wear of the sealing ring body 311, the upper surface of the sealing ring body 311 can be polished and / or sprayed with oil.

[0053] As Figure 1As shown, the cover assembly further includes a mounting base 50 connected below the upper cover 10. The sealing turntable 30 is clamped between the mounting base 50 and the upper cover 10 and can move relative to the mounting base 50 and the upper cover 10. Specifically, the mounting base 50 supports below the sealing turntable 30 and can, together with the upper cover 10, limit the sealing turntable 30 in the up-and-down direction, so that the sealing turntable 30 can only move in the horizontal direction to rotate synchronously with the inner cover 20, ensuring the reliability of the seal.

[0054] This application also provides a cooking appliance, including a cover assembly, wherein the cover assembly is the above-mentioned cover assembly. The above-mentioned cover assembly can effectively solve the problem that the condensed water in the related art easily flows into the space between the upper cover and the inner cover, and the cooking appliance with the above-mentioned cover assembly also has the above-mentioned advantages.

[0055] 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 soybean milk machine, a cooking machine, a stir-fry machine, an electric slow cooker, a multi-functional pot, etc.

[0056] 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", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the drawings. It 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. Therefore, it cannot be understood as a limitation to 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.
