Description

Technical Field

[0001] The technical field of cooking utensils, in particular, relates to a sealing ring, a detachable cover assembly, a cover body and a cooking utensil. Background Art

[0002] Cooking utensils often use a cover assembly to prevent food in the cooking container from coming into direct contact with the plastic cover. This assembly typically consists of a metal cover, a sealing ring, and a plastic bracket. The sealing ring fills the gap between the metal cover and the cooking container, while the plastic bracket secures the sealing ring to the metal cover.

[0003] Current sealing rings have problems such as strong odor, easy to harbor dirt and grime, yellowing after long-term use, large area and unsightly appearance, resulting in a poor user experience.

[0004] Therefore, a sealing ring, a detachable cover assembly, a cover body and a cooking utensil are needed to at least partially solve the above problems. Utility Model Content

[0005] The Summary of the Utility Model introduces a series of simplified concepts that will be further described in the Detailed Description of the Utility Model. The Summary of the Utility Model of the Utility Model does not intend to limit the key features and essential technical features of the claimed technical solution, nor does it intend to determine the scope of protection of the claimed technical solution.

[0006] To at least partially address the above-mentioned problems, the present invention provides, in a first aspect, a sealing ring for sealing between a lid of a cooking utensil and a cooking container. The sealing ring has a central axis. In a cross section of the sealing ring passing through the central axis, the sealing ring has an overall cross-section approximately in the shape of a capital letter G with a vertically downwardly extending portion. The sealing ring comprises:

[0007] a rounded portion, the rounded portion including a portion that is curved and approximately shaped like a capital letter C, and a rounded portion groove formed inside the C-shaped portion;

[0008] The vertical downwardly extending portion forms a sealing portion, and a lower end portion of the sealing portion is used to contact a radially outwardly extending edge of the opening of the cooking container.

[0009] According to the present invention, the sealing ring, in a cross-section taken through its central axis, has an overall cross-section approximately resembling the shape of a capital letter G with a vertically downwardly extending portion. Therefore, the ring can be attached to the lid body via its curved portion, which resembles the shape of a capital letter C, or the curled portion, simplifying installation. Furthermore, the sealing portion extending downward from the curled portion contacts the radially outwardly extending edge of the cooking container, ensuring a good seal between the lid and the cooking container when the lid is closed. This design also minimizes leakage from the sealing ring, making it less likely to harbor dirt and grime. Furthermore, the ring maintains a good sealing function and a pleasant visual appearance even after extended use. Furthermore, odors caused by aging of the sealing ring material are significantly reduced.

[0010] Optionally, the curled portion further includes:

[0011] an active portion connected to the lower tail section of the C-shape; and

[0012] an interference portion connected to the C-shaped upper head section, wherein the action portion and the interference portion overlap with each other in a horizontal projection direction;

[0013] The interference portion is arranged closer to the opening of the groove of the rolled portion than the action portion, so that the extension path of the rolled portion in the circumferential direction constitutes a non-closed curve larger than a circle.

[0014] According to the sealing ring of the present invention, the rolled portion can be used to be installed in the rolled cavity at the edge of the cover body, wherein the interference portion is arranged at the opening of the rolled portion groove closer to the action portion, that is, when the sealing ring is installed, the interference portion is located on the side of the action portion closer to the opening of the rolled cavity, so as to hinder the action portion from moving out of the rolled cavity, thereby increasing the resistance of the rolled portion to escape from the rolled cavity, making the installation of the sealing ring more secure.

[0015] Optionally, a circumferential angle of the C-shaped portion is greater than or equal to 180 degrees.

[0016] According to the sealing ring of the present invention, the C-shaped portion has a larger range in the circumferential direction, so that the action portion and the interference portion can be connected at positions with a larger distance in the circumferential direction, thereby better realizing the obstruction effect of the interference portion on the action portion.

[0017] Optionally, in the assembled state, the rolled portion is accommodated in a rolled cavity with an opening of the cover body, and inverted teeth are provided on the outside of the rolled portion, and the inverted teeth are used to increase the resistance of the rolled portion when it moves toward the opening of the rolled cavity.

[0018] According to the sealing ring of the utility model, the inverted teeth make the sealing ring less likely to fall off.

[0019] Optionally, in a cross section of the sealing ring passing through the central axis, a corner is formed on the outer side of the rounded portion.

[0020] According to the sealing ring of the utility model, when installing the sealing ring, the sealing ring is inserted into the rolled cavity starting from the corner of the rolled portion, so that the sealing ring is easy to install.

[0021] Optionally, in a cross section of the sealing ring passing through the central axis, an outer surface of at least one side of the corner portion includes a straight line.

[0022] According to the sealing ring of the present invention, the outer surface of at least one side of the corner portion outside the rounded portion includes a straight line, so that the rounded portion has little resistance when being installed into the rounded cavity and is easy to install.

[0023] Optionally, in a cross section of the sealing ring passing through the central axis, outer surfaces on both sides of the corner portion include straight lines.

[0024] According to the sealing ring of the present invention, the outer surfaces on both sides of the corners outside the rolled portion include straight lines, so that the rolled portion has little resistance when being installed into the rolled cavity and is easy to install.

[0025] Optionally, the upper end portion of the sealing portion is connected to the end of the lower tail section of the C-shape, and the interference portion is connected to the end of the upper head section of the C-shape.

[0026] Optionally, the end of the upper head section of the C shape extends beyond a preset straight line, wherein the preset straight line is a straight line passing through the end of the lower tail section of the C shape and the connection part of the sealing part and parallel to the central axis of the sealing ring.

[0027] According to the sealing ring of the present invention, the rolled portion can be used to be installed in the rolled cavity at the edge of the cover body, and the end of the C-shaped upper head section extends beyond the first end connected to the sealing portion, so that the interference portion can be arranged at the opening of the rolled portion groove closer to the action portion than the action portion, which can block the action portion from moving out of the rolled cavity and increase the resistance of the rolled portion to escape from the rolled cavity.

[0028] Optionally, along the extending direction of the C-shape, a distance between the acting portion and the sealing portion is smaller than a distance between the acting portion and the interference portion.

[0029] According to the sealing ring of the present invention, along the extension direction of the rolled portion, the action portion is relatively close to the sealing portion, and the interference portion is connected to the action portion at a position at a farther distance, that is, close to the opposite sides of the rolled portion. Therefore, when the action portion is about to move out of the cavity, the force of the interference portion on the action portion is directed toward the groove of the rolled portion.

[0030] Optionally, one end of the C-shape is connected to the outer side of the upper end of the sealing portion, and a portion of the C-shape is lower than the upper surface of the sealing portion. This design allows the rolled portion to be installed more securely.

[0035] According to the removable cover assembly of the present invention, the rolled portion of the sealing ring is located within the rolled cavity, while the interference portion is positioned closer to the opening of the rolled cavity than the active portion. This prevents the active portion from moving out of the rolled cavity, thereby increasing resistance to the rolled portion escaping the cavity and ensuring a more secure installation of the sealing ring. Furthermore, this design allows only the sealing portion of the sealing ring to leak outward, resulting in a simple and aesthetically pleasing design. Dirt and dirt are less likely to accumulate between the sealing ring and the cover plate, allowing the sealing ring to maintain its effective sealing function and visual appeal even after extended use. Odors caused by aging of the sealing ring material are also significantly reduced.

[0036] Optionally, in a cross-section of the cover plate, the rolled cavity is in the shape of an arc curved about a curling axis, and an opening of the rolled cavity is formed between a terminal edge of the arc and the central portion. The cover plate has a simple design and is easy to manufacture, and allows for easy and secure installation of the sealing ring within the rolled cavity.

[0037] Optionally, the arc has a lowest position, and the end edge of the arc is higher than the lowest position of the arc.

[0038] According to the detachable cover assembly of the present invention, the lowest position of the rolled cavity formed by the edge portion is lower than the position of the opening, and the portion extending upward from the lowest position blocks the rolled portion from moving toward the opening, so that the sealing ring is firmly installed.

[0039] Optionally, a central angle corresponding to a circumferential distance between the end edge of the arc and the lowest position of the arc is less than or equal to 50°.

[0040] Further optionally, a central angle corresponding to a circumferential distance between the end edge of the arc and the lowest position of the arc is greater than or equal to 30° and less than or equal to 40°.

[0041] According to the detachable cover assembly of the present invention, the size of the portion extending upward from the lowest position and the size of the opening left are appropriate, so that the curled portion of the sealing ring is not likely to fall off from the curled cavity.

[0042] Optionally, the edge of the central portion has an annular first area, the first area is configured to extend upward, the curled cavity portion is bent downward and then inward relative to the first area, and there is a gap between the end edge of the curled cavity portion and the first area, and the first area constitutes a part of the cavity wall of the curled cavity.

[0043] According to the detachable cover assembly of the present invention, the first area is constructed to extend upward and constitute a part of the wall of the rolled cavity, which can increase the contact area between the wall of the rolled cavity and the sealing ring, has a better anti-falling effect, and the processing difficulty of the rolled cavity is low; the first area is constructed to extend upward, and the height of the rolled cavity relative to the cover body can be adjusted upward, and the lowest position of the rolled cavity will not protrude too much downward from the cover body.

[0044] Optionally, the edge portion further includes a second area, the second area is located between the rolled cavity portion and the first area, and the second area is configured to extend along a plane.

[0045] According to the detachable cover assembly of the present invention, the second area is connected between the rolled cavity and the first area, so that the distance between the end edge and the central portion of the rolled cavity is appropriate, that is, the opening size is appropriate.

[0046] A third aspect of the present invention provides a cover, comprising:

[0047] Liner cover, and

[0048] A detachable cover assembly according to any one of the second aspects, wherein the cover plate is detachably connected to the liner cover, and the outer peripheral side of the rolled cavity portion of the cover plate is used to be connected to the liner cover.

[0049] The lid of this invention features a removable cover plate and lining. Furthermore, the sealing ring is securely mounted, minimizing leakage. The interior of the lid is simple and aesthetically pleasing, and it resists harboring dirt and grime. Even after extended use, the sealing ring maintains its excellent sealing function and visual appeal. Odors caused by aging sealing ring material are also significantly reduced.

[0102] The present application provides a sealing ring, a detachable cover assembly, a cover body and a cooking utensil.

[0103] Now, exemplary embodiments according to the present invention will be described in more detail with reference to the accompanying drawings.

[0104] like Figure 1 and Figure 2As shown, the cooking utensil 100 according to a specific embodiment of the present application mainly includes a lid 10 and a pot body 90. The pot body 90 is basically in the shape of a rounded rectangular parallelepiped and has a cylindrical cooking container storage portion. The cooking container 91 can be freely placed in or removed from the cooking container storage portion to facilitate cleaning of the cooking container 91. The top of the cooking container 91 has a circular opening for placing materials to be heated, such as rice, soup, etc., into the cooking container 91. The opening of the cooking container 91 is provided with a radially outwardly curved edge 92. The lid 10 is basically in the shape of a rounded rectangular parallelepiped and basically corresponds to the shape of the pot body 90. The lid 10 is pivotally connected to the pot body 90 in an openable and closable manner to cover the pot body 90. When the lid 10 is closed on the pot body 90, a cooking space is formed between the lid 10 and the cooking container 91.

[0105] The lid body 10 includes a lining cover 11 and a detachable cover assembly 30, which is detachably connected to the lining cover 11. One side of the lining cover 11 along the length direction is a connecting end that is pivotally connected to the pot body 90, and the other side is a pivot end for opening and closing the lid.

[0106] like Figure 2 and Figure 3 As shown, the detachable cover assembly 30 includes a cover plate 31 and a sealing ring 50. The sealing ring 50 is mounted on the cover plate 31 for sealing between the cover body 10 and the cooking container 91.

[0107] like Figures 3 to 5 As shown, the cover plate 31 is formed with a rolled cavity 34 at its edge for mounting the sealing ring 50. The cover plate 31 includes a central portion 32 and an edge portion 33. The edge portion 33 is connected to the central portion 32 at its periphery. The edge portion 33 is provided with a rolled cavity portion 33A with an opening. The rolled cavity portion 33A constitutes at least a portion of the cavity wall of the rolled cavity 34. The outer periphery of the rolled cavity portion 33A is used to connect to the liner cover 11.

[0108] It should be noted that “up” and “down” in the present application refer to the directions corresponding to the state in which the cooking utensil 100 is placed normally and the lid 10 is covered on the pot body 90 .

[0109] like Figures 3 to 5As shown, the sealing ring 50 has a central axis L2. In a cross-section of the sealing ring 50 through its central axis L2, the overall cross-section of the sealing ring 50 resembles a capital letter G with a vertically extending downward portion. The lower end of the sealing ring 50 (i.e., the lower end of the vertically extending downward portion) protrudes downwardly from the lowest point of the lower surface of the cover plate 31. When the lid 10 covers the pot body 90, the lower end of the sealing ring 50 contacts the opening of the cooking container 91, for example, the upper surface of the radially extending rim 92, to seal between the lid 10 and the cooking container 91. The width of the radially extending rim 92 is, for example, 5 mm to 25 mm, for example, 10 mm.

[0110] The sealing ring 50 includes a rolled portion 51 and a sealing portion 52. Specifically, in a cross section of the sealing ring 50 through its central axis L2, the rolled portion 51 includes a portion that is curved and close to the shape of a capital letter C, and a rolled portion groove 51C is formed on the inner side of the C-shaped portion. The opening (notch) 51F of the rolled portion groove 51C is closer to the opening of the rolled cavity 34 than the groove bottom 51G of the rolled portion groove 51C. The vertically downward extension forms the sealing portion 52, the upper end portion 52A of the sealing portion 52 is connected to the rolled portion 51, and the lower end portion 52B of the sealing portion 52 is used to contact the radially outward edge 92 at the opening of the cooking container 91. The rolled portion 51 is accommodated in the rolled cavity 34 to mount the sealing ring 50 to the cover plate 31. The sealing portion 52 extends from the connection with the rolled portion 51 to the outside of the rolled cavity 34. In this way, the sealing ring can be easily installed, has a small leakage area, and is not easy to hide dirt and grime, thereby further improving the problem that the sealing ring turns yellow after long-term use, affecting the appearance and having a strong odor.

[0111] The curling portion 51 further includes an action portion 55 and an interference portion 56. The interference portion 56 is connected to the upper head section 51E of the C shape, and the action portion 55 is connected to the lower tail section 51D of the C shape. The action portion 55 and the interference portion 56 overlap with each other in the horizontal projection direction, as shown in FIG. Figure 4 In the figure, a is the horizontal projection of the interference portion 56, and b is the horizontal projection of the action portion 55, and a and b at least partially overlap. Moreover, the interference portion 56 is arranged closer to the opening of the rolling portion groove 51C than the action portion 55. Thus, the extension path of the rolling portion 51 in the circumferential direction constitutes a non-closed curve that is larger than one circle. In other words, the upper end portion 52A of the sealing portion 52, the action portion 55, and the interference portion 56 are sequentially connected to the rolling portion 51 along the extension direction of the rolling portion 51, and the action portion 55 and the interference portion 56 protrude toward the interior of the rolling portion groove 51C. The interference portion 56 is located on the side of the action portion 55 facing the opening 51F of the rolling portion groove 51C and blocks at least a portion of the action portion 55. In other words, the interference portion 56 is closer to the opening of the rolling cavity 34 than the action portion 55, and the interference portion 56 extends between the action portion 55 and the opening of the rolling cavity 34.

[0112] When the sealing portion 52 is subjected to an external force, causing the curled portion 51 to escape from the curled cavity 34, because the sealing ring 50 is soft and elastic (a non-rigid component), the curled portion 51 is sequentially subjected to force along its curved direction, starting from the connection point with the sealing portion 52, and thus moves toward the opening of the curled cavity 34. When the action portion 55 moves, the interference portion 56 has not yet moved, and thus can block the action portion 55 at a position near the opening of the curled cavity 34, hindering its movement toward the opening of the curled cavity 34. Therefore, the provision of the action portion 55 and the interference portion 56 can increase the resistance of the curled portion 51 to escape from the curled cavity 34, making the installation of the sealing ring 50 more secure.

[0113] Optionally, in the cross section of the sealing ring 50 through the central axis L2, the circumferential angle of the substantially C-shaped portion is greater than or equal to 180 degrees, that is, the circumferential angle of the portion around the curling axis L (such as Figures 4 to 6 (as shown) bends and extends at least half a circle. In this way, the action portion 55 and the interference portion 56 can be connected to substantially opposite sides of the rolled portion 51, for example, the circumferential angle of the rolled portion 51 between the connection positions of the action portion 55 and the interference portion 56 is greater than 180 degrees. As a result, the interference portion 56 can easily extend to the side of the action portion 55 facing the opening 51F of the rolled portion groove 51C, thereby better achieving its obstruction effect on the action portion 55. Furthermore, the rolled portion 51 can occupy most of the space within the rolled cavity 34, making it more securely installed within the rolled cavity 34.

[0114] Along the extension direction of the C-shape of the rolled portion 51, the distance between the action portion 55 and the sealing portion 52 is smaller than the distance between the action portion 55 and the interference portion 56, that is, along the extension direction of the C-shape, the action portion 55 is closer to the sealing portion 52, so that the action portion 55 and the interference portion 56 are connected at approximately opposite positions of the rolled portion 51.

[0115] Optionally, the upper end 52A of the sealing portion 52 is connected to the end of the C-shaped lower tail section 51D, and the interference portion 56 is connected to the end of the C-shaped upper head section 51E. The end of the C-shaped upper head section 51E extends beyond a predetermined straight line L1. For example, the predetermined straight line L1 is a straight line passing through the connection between the end of the C-shaped lower tail section 51D and the sealing portion 52 and parallel to the central axis L2 of the sealing ring 50. In this way, the interference portion 56 can be positioned on the path of the action portion 55 from exiting the cavity, thereby blocking the action portion 55 from moving out of the curling cavity 34 and increasing the resistance to the curling portion 51 from exiting the cavity 34.

[0116] Preferably, if Figure 5As shown, the outer side of the rolled portion 51 is provided with inverted teeth 53. The inverted teeth 53 are used to increase the resistance of the rolled portion 51 when moving toward the opening of the rolled cavity 34, making the sealing ring 50 more securely installed and less likely to fall off. Specifically, the direction from the root of the inverted teeth 53 to the tip of the inverted teeth 53 is a first direction D1, and the direction from the inside of the rolled cavity 34 to the outside of the rolled cavity 34 along the axis of the opening of the rolled cavity 34 is a second direction D2. The angle between the first direction D1 and the second direction D2 is an acute angle. Therefore, when the rolled portion 51 tends to move outward from the rolled cavity 34, the inverted teeth 53 can hinder the outward movement of the rolled portion 51, making it less likely for the sealing ring 50 to fall off from the rolled cavity 34. The inverted teeth 53 can be provided at least in the portion of the rolled portion 51 where friction with the inner wall of the rolled cavity 34 occurs when the rolled portion 51 moves outward.

[0117] Optionally, a corner 54 is formed on the outside of the curled portion 51 in a cross-section of the sealing ring 50 passing through the central axis L2. Corner 54 is formed, for example, on the outside of the groove bottom 51G of the curled portion groove 51C. When installing the sealing ring 50, the curled portion 51 is inserted into the curled cavity 34 starting from the corner 54, making it easier to install the curled portion 51 into the curled cavity 34.

[0118] Preferably, in a cross section of the sealing ring 50 through the central axis L2, the outer surface of at least one side of the corner portion 54 includes a straight line. Figure 5 As shown, the outer surface of the upper side of the corner portion 54 includes a straight line. More preferably, as Figure 4 As shown, the outer surfaces of both sides of the corner portion 54 are straight lines. That is, in a cross section of the sealing ring 50 through its central axis L2, the upper and lower sides of the corner portion 54 are both straight lines. This reduces resistance when the curled portion 51 is inserted into the curled cavity 34, making installation easier.

[0119] Preferably, one end of the C-shape is connected to the outside of the upper end portion 52A of the sealing portion 52, and a portion of the C-shape is lower than the upper surface of the sealing portion 52. That is, a portion of the curled portion 51 is lower than the opening of the curled cavity 34, so that the curled portion 51 is more firmly in the curled cavity 34 and is not easy to fall off.

[0120] like Figure 4 and Figure 5 As shown, the rolled cavity portion 33A can bend at least downward and then inward relative to the central portion 32, thereby enclosing a rolled cavity 34 together with the central portion 32. A gap is provided between the distal edge 35 of the rolled cavity portion 33A and the central portion 32, forming the opening of the rolled cavity 34. Here, "inward" refers to the direction from the edge of the cover plate 31 toward the center. The downward and inward bending of the rolled cavity portion 33A includes a shape formed by multiple bends to form a downward and inward extension.

[0121] Optionally, the curled cavity portion 33A may bend downward, inward, and then upward relative to the central portion 32. That is, the curled cavity portion 33A extends past the lowest position of the curled cavity 34 and then continues to bend upward.

[0122] Optionally, when the sealing ring 50 and the cover plate 31 are assembled, the central axis L2 of the sealing ring 50 is also the central axis of the cover plate 31. In a cross-section of the cover plate 31 passing through its central axis, the curled cavity 33A is in the shape of an arc curved around a curling axis. For example, when the sealing ring 50 and the cover plate 31 are assembled, the curled cavity 33A is in the shape of an arc curved around the curling axis L. A gap exists between the end edge 35 of the arc and the central portion 32. The opening of the curled cavity 34 is formed between the end edge 35 of the arc and the central portion 32. Preferably, in a cross-section of the cover plate 31 passing through its central axis, the curled cavity 33A curves downward and then inward into an arc shape. For the arc-shaped curled cavity 33A, the curling axis passes through the center of the cross-section of the curled cavity 33A. Optionally, the curled cavity 33A is in the shape of an arc with an outer diameter of 3 mm to 15 mm. Preferably, the rolled cavity portion 33A is formed into an arc shape with an outer diameter of 6 mm to 15 mm. However, the rolled cavity portion 33A in the present application is not limited to an arc shape, and may also be a C-shaped curve of other shapes.

[0123] The arc has a lowest position 36, and the end edge 35 of the arc is higher than the lowest position 36 of the arc. Optionally, the central angle θ corresponding to the circumferential distance between the end edge 35 of the arc and the lowest position 36 of the arc is less than or equal to 50°. Preferably, the central angle θ corresponding to the circumferential distance between the end edge 35 of the arc and the lowest position 36 of the arc is greater than or equal to 30° and less than or equal to 40°. That is, after the curling cavity portion 33A bends below the curling axis (i.e., the lowest position 36), it has a portion that continues to extend upward and inward. Therefore, the opening of the curling cavity 34 is higher than the bottom of the curling cavity 34, and the opening size of the curling cavity 34 is appropriate, which can prevent the curling portion 51 from falling off from the curling cavity 34, making the connection between the sealing ring 50 and the cover plate 31 more secure.

[0124] Optionally, the central portion 32 has an annular first region 32A, which is configured to extend upward. The curled cavity portion 33A is curved at least downward and then inward relative to the first region 32A. A gap is provided between the terminal edge 35 of the curled cavity portion 33A and the first region 32A, and the first region 32A constitutes a portion of the cavity wall of the curled cavity 34. It should be noted that, in a cross section of the cover plate 31 passing through its central axis, the upward extension of the first region 32A can be along a straight line or along a curve. For example, in a cross section of the cover plate 31 passing through its central axis, the first region 32A is connected to the curled cavity portion 33A and forms an arc of the same circle.

[0125] Furthermore, if Figure 4 and Figure 5 As shown, the edge portion 33 further includes a second region 33B. The second region 33B is located between the rolled cavity portion 33A and the first region 32A. The second region 33B is configured to extend along a plane.

[0126] According to the removable cover assembly 30 of the present application, the opening of the rolled cavity 34 is appropriately sized, making the sealing ring 50 less likely to fall off, with only the sealing portion 52 leaking outward. This creates a simple, aesthetically pleasing design that is less susceptible to dirt and grime. The interference portion 56 prevents the action portion 55 from moving outward from the rolled cavity 34, further strengthening the secure installation of the sealing ring 50. The large contact area between the wall of the rolled cavity 34 and the sealing ring 50 provides a better anti-falloff effect. Furthermore, the relative height of the rolled cavity 34 and the main body of the cover plate 31 can be adjusted to ensure that the lowest point of the rolled cavity 34 does not protrude excessively from the main body of the cover plate 31.
