Description

Technical Field

[0001] The utility model relates to the technical field of cooking utensils, in particular to 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 complex installation, easy to harbor dirt and grime, yellowing and strong odor after long-term use, large area and unsightly appearance, resulting in poor user experience.

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

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 solve the above problems, the first aspect of the present invention provides a detachable cover assembly for detachably mounting on a liner cover of a cover of a cooking utensil, the detachable cover assembly comprising:

[0007] a cover plate having a center and a central axis passing through the center, wherein in a cross section passing through the central axis, an edge portion of the cover plate forms a curling cavity having a curling cavity opening; and

[0008] A sealing ring connected to the cover plate and used for sealing between the cover of the cooking utensil and the cooking container, the sealing ring comprising:

[0009] an accommodated portion, the accommodated portion being located in the curled cavity; and

[0010] A sealing portion, the sealing portion is located outside the rolled cavity and connected to the accommodated portion, and the two form a connecting portion of the sealing ring;

[0011] The connecting portion passes through the opening of the rolled cavity and forms a snap fit there; the sealing portion has a lower end portion that protrudes from the lowest point of the lower surface of the cover plate by a distance a1, and 0<a1≤3mm.

[0012] According to the removable lid assembly of the present invention, the housing of the sealing ring is located within the rolled cavity, allowing the sealing ring to be mounted to the cover plate. The sealing portion is located outside the rolled cavity, providing a seal between the lid body and the cooking container. The connecting portion passes through the opening of the rolled cavity and forms a snap fit there, making the installation of the sealing ring more secure. The connecting portion snaps into the opening of the rolled cavity, further preventing steam, dirt, and the like from entering the rolled cavity. Furthermore, this design of the removable lid assembly facilitates the installation of the sealing ring, making it less likely to fall off. It also minimizes the leakage area of the sealing ring, resulting in a simple and aesthetically pleasing design that is less likely to harbor dirt and grime, significantly improving the problem of the sealing ring turning yellow and developing a strong odor over time.

[0101] The present application provides a detachable cover assembly, a cover body and a cooking utensil.

[0102] Now, exemplary embodiments according to the present invention will be described in more detail with reference to the accompanying drawings.

[0103] like Figure 1 and Figure 2 As 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 generally in the shape of a rectangular parallelepiped with rounded corners and has a cylindrical cooking container storage portion. A cooking container 91 can be freely placed in or removed from the cooking container storage portion, making it easy to clean the cooking container 91. The top of the cooking container 91 has a circular opening for placing ingredients 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 generally in the shape of a rectangular parallelepiped with rounded corners and substantially 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.

[0104] 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.

[0105] 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.

[0106] like Figures 3 to 6 As shown, the cover plate 31 is formed with a curling cavity 34 at the edge for installing the sealing ring 50, and the curling cavity 34 has a curling cavity opening 36. The cover plate 31 has a center and a central axis L2 passing through the center (as shown in FIG. Figure 3 (As shown). The sealing ring 50 has a central axis, and when assembled with the cover plate 31, the central axis of the sealing ring 50 coincides with the central axis L2 of the cover plate 31. The sealing ring 50 is connected to the cover plate 31, and its lower end 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 flared edge 92, to seal between the lid 10 and the cooking container 91. The width of the radially flared edge 92 is, for example, 5-25 mm, for example, 10 mm.

[0107] 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 .

[0108] like Figures 4 to 7 As shown, the sealing ring 50 includes a sealing portion 52 and an accommodated portion 56. The accommodated portion 56 enters the rolled cavity 34 through the rolled cavity opening 36. The sealing portion 52 is located outside the rolled cavity 34 and is connected to the accommodated portion 56, forming a connecting portion 57 of the sealing ring 50 therebetween. The connecting portion 57 passes through the rolled cavity opening 36 and forms a snap fit there, that is, the connecting portion 57 blocks the rolled cavity opening 36, thereby preventing steam, dirt, etc. from entering the rolled cavity 34. The upper end 52A of the sealing portion 52 is connected to the active portion 55 through the connecting portion 57. The sealing portion 52 has a lower end 52B that protrudes from the lowest point of the lower surface of the cover plate 31 by a distance a1, and 0<a1≤3mm. The lower end 52B is used to contact the radially outward edge 92 at the opening of the cooking container 91. Therefore, only the sealing portion 52 of the sealing ring 50 is exposed, which is simple and beautiful, not easy to harbor dirt and grime, greatly improving the problem of the sealing ring turning yellow and having a strong odor after long-term use, and is easy to install.

[0109] The accommodated portion 56 includes an operating portion 55. In a cross-section through the central axis L2, the two ends of the operating portion 55 abut against opposing inner walls of the rolling cavity 34. The operating portion 55 and the sealing portion 52 are located on either side of a connecting portion 57 and are connected by this connecting portion 57. The operating portion 55, connecting portion 57, and sealing portion 52 together roughly form an inclined T-shape. Due to the elasticity of the material of the sealing ring 50, the head of this T-shape abuts against the inner wall of the rolling cavity 34 with a certain external tension. Under the action of the rolling cavity wall, the operating portion 55 is clamped therein, making it difficult to escape.

[0110] The action portion 55 divides the rolling cavity 34 into a first cavity 34A and a second cavity 34B. The first cavity 34A is located on the side of the action portion 55 facing away from the rolling cavity opening 36, and the second cavity 34B is located on the side of the action portion 55 facing the rolling cavity opening 36. At each abutment 39 between the action portion 55 and the inner wall of the rolling cavity 34, the inner wall has a first inner wall 37 extending from the abutment 39 to the rolling cavity opening 36 and a second inner wall 38 extending from the abutment 39 to the other abutment 39. At the abutment 39, the first inner wall 37 extends toward the axis L1 of the rolling cavity opening 36 (as shown in FIG. 2 ). Figure 4 As shown in FIG5 , the first inner wall 37 extends in the direction of the first cavity 34A at the abutment 39 to apply a force to both ends of the action portion 55. Here, the extension direction of the first inner wall 37 at the abutment 39 can be understood as the slope or tangent direction of the first inner wall 37 at the abutment 39. That is, from the position of the abutment 39 close to the roll cavity opening 36, the distance between the opposite inner walls of the roll cavity 34 is smaller than the extension size of the action portion 55. Therefore, when the action portion 55 is pulled out of the cavity through the sealing portion 52, the two ends of the action portion 55 are respectively subjected to the support force from the first inner wall 37 of the roll cavity 34 toward the cavity, thereby making it difficult for the action portion 55 to be pulled out of the roll cavity 34, thereby ensuring that the sealing ring 50 is firmly installed.

[0111] Optionally, the sealing portion 52 is connected to the middle of the action portion 55 through the connecting portion 57 rather than to the end of the action portion 55, so that when the action portion 55 is pulled out of the cavity by the sealing portion 52, both ends are supported by the first inner wall 37, thereby better exerting the resistance effect.

[0112] Optionally, the middle portion of the action portion 55 is bent toward a side away from the sealing portion 52. For example, the action portion 55 is bent in an arc C-shape toward the first cavity 34A, or the action portion 55 is formed with a corner portion protruding toward the first cavity 34A at the middle portion. This makes it difficult for the action portion 55 to deform toward the side of the rolled cavity opening 36, thereby providing greater resistance to the sealing ring 50 from falling off.

[0113] Optionally, the acting portion 55 is substantially perpendicular to the axis L1 of the curling cavity opening 36 , so that the acting portion 55 is not easily pulled out of the curling cavity opening 36 .

[0114] Optionally, the accommodated portion 56 further includes a curled portion 51. The curled portion 51 is accommodated in the curled cavity 34, is connected to the end of the active portion 55, and at least a portion of the curled portion 51 is farther from the curled cavity opening 36 than the active portion 55, that is, the curled portion 51 is accommodated in the first cavity 34A.

[0115] The sealing ring 50 has a radially symmetrical structure, for example, its cross-sectional shape remains unchanged. In a cross-section passing through the central axis L2, the curled portion 51 exhibits a curved shape, such as a C-shaped curve, a U-shaped curve, or a J-shaped curve. Alternatively, in a cross-section passing through the central axis L2, the curled portion 51 is configured to curve about the curling axis L. This provides a large contact area between the sealing ring 50 and the inner wall of the curled cavity 34, and the curled portion 51 fills most of the space within the curled cavity 34, further stabilizing the accommodated portion 56 within the cavity. This prevents the sealing ring 50 from shaking and becoming easily dislodged.

[0116] Preferably, the outer side of the curled portion 51 is provided with an inverted tooth 53, which is used to increase the resistance of the curled portion 51 when it moves toward the curled cavity opening 36, so that the installation of the sealing ring 50 is more secure and not easy to fall off. Figure 5 As shown, the direction from the root of the inverted tooth 53 to the tip of the inverted tooth 53 is a first direction D1, and the direction from the inside of the curling cavity 34 to the outside of the curling cavity 34 along the axis of the opening of the curling 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 curling portion 51 tends to move outward from the curling cavity 34, the inverted teeth 53 can hinder the outward movement of the curling portion 51, preventing the sealing ring 50 from falling out of the curling cavity 34. The inverted teeth 53 can be located at least in the portion of the curling portion 51 where friction with the inner wall of the curling cavity 34 occurs during outward movement.

[0117] Optionally, a corner 54 is formed on the outside of the curled portion 51 in a cross section passing through the central axis L2. For example, a corner 54 is formed on the outside of the portion of the curled portion 51 away from the curled cavity opening 36. 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 in the curled cavity 34.

[0118] Preferably, in a cross section through the central axis L2, the outer surface of at least one side of the corner portion 54 includes a straight line. Figure 4 and Figure 5 As shown, the outer surface of the upper side of the corner portion 54 includes a straight line. More preferably, as Figure 6 As shown, the outer surfaces of both sides of the corner portion 54 are straight lines. That is, in a cross section through the 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 curling cavity 34, making installation easier.

[0119] like Figures 4 to 6 As shown, the cover plate 31 includes a central portion 32 and an edge portion 33. The edge portion 33 is on the periphery of the central portion 32 and is connected to the central portion 32. The edge portion 33 is provided with a rolled cavity portion 33A with an opening, and the outer peripheral side of the rolled cavity portion 33A is used to connect with the lining cover 11. The rolled cavity portion 33A is bent at least downward and then inward to enclose a rolled cavity 34, that is, the rolled cavity 34 is at least partially surrounded by the rolled cavity portion 33A. Here, "inward" refers to the direction from the edge of the cover plate 31 toward the middle. The downward and inward bending of the rolled cavity portion 33A includes a shape extending downward and inward formed by multiple bending.

[0120] The curled cavity portion 33A can also bend downward, inward, and then upward relative to the central portion 32. That is, the curled cavity portion 33A extends past the lowest point of the curled cavity 34 and then continues to bend upward. This allows a portion of the accommodated portion 56 to be lower than the sealing portion 52, making it difficult for the accommodated portion 56 to escape from the curled cavity 34.

[0121] Optionally, in a cross section passing through the central axis L2, the rolled cavity portion 33A is bent into an arc shape around the curling axis (for example, the curling axis L of the rolled portion 51 in the assembled state), and the rolled cavity opening 36 is formed between the end edge 35 of the arc and the central portion 32. Preferably, in a cross section passing through the central axis L2, the rolled cavity portion 33A is bent downward and then inward into an arc shape. For the arc-shaped rolled cavity portion 33A, the curling axis L passes through the center of the cross section of the rolled cavity portion 33A. Optionally, the rolled cavity portion 33A forms an arc shape with an outer diameter of 3 mm to 15 mm. Preferably, the rolled cavity portion 33A forms 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.

[0122] Furthermore, the arc of the rolled cavity portion 33A has a lowest position 40, the end edge 35 of the arc is higher than the lowest position 40 of the arc, and the central angle θ corresponding to the circumferential distance between the end edge 35 of the arc and the lowest position 40 of the arc (as shown in FIG. Figure 5 The angle of the curved cavity 33A is preferably less than or equal to 50°. Preferably, the central angle θ corresponding to the circumferential distance between the arc's terminal edge 35 and the arc's lowest position 40 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 L (i.e., the lowest position 40), it has a portion that continues to extend upward and inward. Thus, the curling cavity opening 36 is higher than the bottom of the curling cavity 34, and the curling cavity opening 36 is appropriately sized to prevent the accommodated portion 56 from falling out of the curling cavity 34, thereby making the connection between the sealing ring 50 and the cover plate 31 more secure.

[0123] Optionally, the central portion 32 has an annular first region 32A that extends upward. The curled cavity portion 33A curves at least downward and then inward relative to the first region 32A. A gap is defined between the distal edge 35 of the curled cavity portion 33A and the first region 32A. The first region 32A constitutes a portion of the wall of the curled cavity 34. It should be noted that, in a cross section passing through the central axis L2, the upward extension of the first region 32A can be along a straight line or a curved line. For example, in a cross section passing through the central axis L2, the first region 32A and the curled cavity portion 33A are connected and form an arc of the same circle.

[0124] Furthermore, the edge portion 33 includes a second region 33B located between the rolled cavity portion 33A and the first region 32A. The second region 33B is configured to extend along a plane. The combination of the first region 32A and the second region 33B elevates the rolled cavity 34, allowing the rolled cavity opening 36 to face generally downward, thereby further strengthening the connection between the sealing portion 52 and the active portion 55. Furthermore, the combination of the first region 32A and the second region 33B makes the rolled cavity 34 easier to manufacture and allows for flexible adjustment of the size of the rolled cavity opening 36.
