[0026] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar numbers throughout represent the same or similar elements or elements with the same or similar functions.

[0027] In this utility model, unless otherwise specified or limited, the terms "assemble," "connect," and "connect" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection; direct connection, connection through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0028] The following description of the embodiments of the present invention is provided in conjunction with the accompanying drawings to further describe the specific embodiments of the present invention so that the technical solutions and beneficial effects of the present invention are more clearly understood. The following description of the embodiments with reference to the accompanying drawings is for illustrative purposes only and is intended to explain the present invention, but is not to be construed as limiting the present invention.

[0029] The preferred embodiment provided by the present invention is as follows: Figures 1-8As shown, a cover structure of a cooking utensil includes an upper cover assembly 1, a lower lining plate 2 fixedly connected to the bottom of the upper cover assembly 1, and a pot cover assembly 3 fixedly connected to the bottom of the lower lining plate 2. The lower lining plate 2 is provided with a base 21, side panels 22, and a top plate 23. The side panels 22 are respectively provided vertically at both ends of the base 21. The lower ends of the side panels 22 are fixed to the base 21, and the top plate 23 is provided horizontally at the upper ends of the side panels 22. The base 21, the two side panels 22, and the top plate 23 are connected end to end and enclose a gripping space 25; the user's fingers can pass through the gripping space 25 and grip the lower lining plate 2; the upper cover assembly 1 and the lower lining plate 2 enclose an installation space. The side panel 22, facing away from the gripping space 25, is provided with a horizontally extending elastic mounting portion 221, which is elastically connected to the upper cover assembly 1. Fasteners secure the elastic mounting portion 221 to the upper cover assembly 1. Due to production or assembly errors, the elastic mounting portion 221 can deform after installation, and in severe cases, the base of the elastic mounting portion 221 can suffer irreversible damage. The elastic connection of the elastic mounting portion 221 to the upper cover assembly 1 avoids this problem. The base 21 is provided with a vertical mounting portion 212, which extends vertically toward the pot lid assembly 3. Connectors 24 are provided between the upper portion of the vertical mounting portion 212 and the cantilevered end of the elastic mounting portion 221. Connectors 24 support the elastic mounting portion 221 and enhance the overall structural strength, while preventing deformation of the elastic mounting portion 221 from exceeding a predetermined value under various operating conditions (assembly or demolding during manufacturing). The elastic mounting portion 221, vertical mounting portion 212, and connector 24 are all located within the installation space. When the user holds the cover body, the user's hand will directly contact the upper cover assembly 1 and the lower lining plate 2.

[0030] In an optional embodiment, the connector 24 can be a rod-shaped structure or a plate-shaped structure. The connector 24 can be integrally formed with the elastic mounting portion 221 and the vertical mounting portion 212 to improve the integrity and stability of the structure. Alternatively, the connector 24 can be integrally formed with the elastic mounting portion 221 or the vertical mounting portion 212. In this case, one end of the connector 24 is not fixedly connected to the elastic mounting portion 221 or the vertical mounting portion 212, but abuts against the elastic mounting portion 221 or the vertical mounting portion 212. One end of the connector 24 is free, and the connection between the one end of the connector 24 and the elastic mounting portion 221 or the vertical mounting portion 212 can be considered a hinged connection in structural mechanics. The connector 24 only transfers its axial load to the elastic mounting portion 221 or the vertical mounting portion 212, and does not transfer bending moment. This increases the deformability of the elastic mounting portion 221 while ensuring the connection strength of the overall structure, and also avoids unnecessary deformation.

[0031] In this embodiment, a deformable portion 2212 is provided at the base of the elastic mounting portion 221. The deformable portion 2212 is composed of a groove structure. In an alternative embodiment, the elastic mounting portion 221 may be provided with at least one groove structure. The more groove structures provided, the greater the deformability of the elastic mounting portion 221.

[0032] like Figures 3-4 As shown, the elastic mounting portion 221 is generally fan-shaped, with the base of the elastic mounting portion 221 being arc-shaped. Correspondingly, the shape of the groove structure of the deformable portion 2212 matches the shape of the base of the elastic mounting portion 221. To enhance the strength of the elastic mounting portion 221, the ends of the groove structure of the deformable portion 2212 do not penetrate the upper surface of the elastic mounting portion 221.

[0033] In this embodiment, the upper cover assembly 1 includes an upper cover housing 11 and a lower cover mounting portion 15 extending downwardly from the upper cover housing 11. The upper cover mounting portion 15 is detachably connected to the elastic mounting portion 221. A first mounting hole 151 provided on the upper cover mounting portion 15 is arranged opposite a second mounting hole 2211 on the elastic mounting portion 221. The upper cover assembly 1 and the lower liner 2 are secured together by tightening screws in the first mounting hole 151 and the second mounting hole 2211.

[0034] In an optional embodiment, the upper cover mounting portion 15 and the elastic mounting portion 221 may be respectively installed with a buckle and a slot, so that the upper cover mounting portion 15 and the elastic mounting portion 221 can be quickly assembled and fixed by snap connection.

[0035] In this embodiment, the edge of the upper cover shell 11 extends toward the lower lining plate 2 to form a first extension portion 12, a second extension portion 13, and a third extension portion 14; the first extension portion 12, the second extension portion 13, and the third extension portion 14 are respectively abutted against the top plate 23, the side plate 22, and the base 21 in turn. The first extension portion 12, the second extension portion 13, and the third extension portion 14 are generally long strip-shaped plate-like structures. After assembly, the first extension portion 12, the second extension portion 13, and the third extension portion 14 are all embedded in the lower lining plate 2. The lower lining plate 2 has a positioning and limiting effect on the upper cover shell 11. During the installation process, under the action of the positioning structure of the lower lining plate 2, the upper cover shell 11 can be quickly installed on the lower lining plate 2; and under the action of the limiting structure, the lower lining plate 2 can limit the lateral and longitudinal displacement of the upper cover shell 11, thereby improving the stability of the overall structure.

[0036] In this embodiment, the top plate 23 is provided with a first matching portion 231 matching the first extension portion 12; the side plate 22 is provided with a second matching portion 222 matching the second extension portion 13; the base 21 is provided with a third matching portion 213 matching the third extension portion 14. 。The first mating portion 231 can be a groove structure, a step structure, or a sidewall structure protruding from the edge of the top plate 23 toward the upper cover shell 11. Since the lower liner 2 is a generally elongated strip, the first mating portion 231 is located on both sides of the top plate 23 in the longitudinal direction. The first mating portion 231 can limit the lateral displacement of the upper cover shell 11, improving the stability of the overall structure. The first extension 12 is coupled to the first mating portion 231, and the first mating portion 231 also has a mounting and positioning function for the upper cover shell 11 during assembly. The second mating portion 222 can be a groove structure, a step structure, or a sidewall structure protruding from the edge of the side plate 22 toward the upper cover shell 11. Since the lower liner 2 is a generally elongated strip in height, the second mating portion 222 is located on both sides of the side plate 22 in the longitudinal direction. The second mating portion 222 can limit the lateral displacement of the upper cover shell 11, improving the stability of the overall structure. The second extension 13 is coupled to the second mating portion 222, and the second mating portion 222 also has a mounting and positioning function for the upper cover shell 11 during assembly. The third matching portion 213 can be a groove structure, a step structure or a side wall structure protruding from the edge of the base 21 toward the upper cover shell 11; since the lower lining plate 2 is roughly a long strip structure in the length direction, the third matching portion 213 is arranged at both ends of the base 21 of the lower lining plate 2, and the third matching portion 213 can limit the longitudinal displacement of the upper cover shell 11 and improve the stability of the overall structure; at the same time, the third extension portion 14 is coupled to the third matching portion 213, and the third matching portion 213 also has the function of installing and positioning the upper cover shell 11 during assembly.

[0037] In an optional embodiment, the first matching portion 231 is a groove structure, and the first extension portion 12 can be embedded in the groove structure. The groove structure can limit and position the first extension portion 12 through the groove walls on both sides of the groove structure itself.

[0038] In an optional embodiment, the second mating portion 222 is a step structure extending from the interior of the lower lining plate 2 and sinking toward the holding space 25; the second extension portion 13 abuts against the step structure, and the upper cover shell 11 is limited and positioned by abutment. At the same time, since the step structure is formed by sinking, the edge of the side panel 22 is protruding relative to the step structure, and the protrusion of the edge of the side panel 22 can also have a lateral limiting effect on the second extension portion 13.

[0039] In optional embodiments, the third matching part 213 is a side wall structure protruding upward from the edge of the base 21 toward the direction of the housing 11. It can be considered that the third matching part 213 is a plate-shaped side wall structure extending from the edge of the base 21 upward toward the direction of the housing 11, that is, the third matching part 213 can be used as a surface housing of the lower lining plate 2. The third extending part 14 abuts against the inner side wall of the third matching part 213, and the third matching part 213 limits the longitudinal displacement of the third extending part 14. In the present embodiment, the plane of the base 21 is in a runway shape, and the arc-shaped structures at both ends of the base 21 can simultaneously limit the lateral and longitudinal displacement of the third extending part 14.

[0040] In some optional embodiments, a boss is arranged between two adjacent third matching parts 213 on the same side, and the boss is arranged at the top of the vertical mounting part 212 and connected with the connecting piece 24. On the one hand, it is used to improve the connection strength between the vertical mounting part 212 and the connecting piece 24 and improve the stability. On the other hand, it is used to improve the connection strength between the vertical mounting part 212 and the base 21, so as to avoid damage to the connection between the vertical mounting part 212 and the base 21 under the condition of overload external force. A notch is arranged between two adjacent third extending parts 14 on the same side. The notch is matched with the boss.

[0041] It should be noted that the forms of the first matching part 231, the second matching part 222, and the third matching part 213 are various, and the main purpose is to achieve the limiting and positioning effect of the upper housing 11. Other forms of the first matching part 231, the second matching part 222, and the third matching part 213 can refer to the structures shown in the optional embodiments. The skilled in the art can freely combine within a limited range, which belongs to the protection scope of the present patent.

[0042] In the present embodiment, the edge of the base 21 extends downward to form a surrounding structure 211, and the surrounding structure 211 abuts against the pot cover assembly 3. The shape of the lower surface of the surrounding structure 211 is adapted to the contour of the upper surface of the pot cover assembly 3. The edge of the lower surface of the base 21 extends downward to form the surrounding structure 211 toward the direction of the pot cover assembly 3, so as to reduce the contact area between the base 21 and the pot cover assembly 3, and to tightly fit the upper surface of the pot cover assembly 3 within the limited deformation of the material of the base 21, thereby avoiding the production error caused by the production process to form a large gap between the base 21 and the pot cover assembly 3 after contacting each other, which affects the use or the user's visual perception.

[0043] In the embodiment, the lid assembly 3 is composed of two components, including a cover plate 31 and a side wall 32 fixed around the cover plate 31; the cover plate 31 and the side wall 32 define the upper cooking space of the cooking appliance. The cover plate 31 is provided with a fixed mounting hole 311, and one end of the vertical mounting portion 212 is embedded in or penetrates through the fixed mounting hole 311. The third mounting hole 2121 of the vertical mounting portion 212 is arranged opposite to the fixed mounting hole 311 of the cover plate 31; the vertical mounting portion 212 can be arranged on one side of the fixed mounting hole 311 or in the mounting hole; the position of the vertical mounting portion 212 relative to the fixed mounting hole 311 depends on the type of fastener used; when the fastener is relatively long and the diameter of one end is larger than the diameter of the fixed mounting hole 311, the vertical mounting portion 212 can be arranged on the side of the fixed mounting hole 311 close to the base 21 or in the mounting hole; when the fastener is relatively short and the diameter of one end is larger than the diameter of the fixed mounting hole 311, the vertical mounting portion 212 can be arranged through the fixed mounting hole 311, and the end of the vertical mounting portion 212 can be flush with or slightly protrude from the surface of the cover plate 31. The cover plate 31 and the side wall 32 can be made of the same material. In some embodiments, the cover plate 31 can be made of a transparent material such as glass.

[0044] In the embodiment, one end of the side wall 32 is close to the cover plate 31 and is provided with a stepped structure, and the cover plate 31 is arranged on the stepped structure; the side wall 32 is made of a metal material and can be formed by die casting or stamping. The stepped structure can better enable the cover plate 31 to be mounted on the side wall 32, and then the side wall 32 and the cover plate 31 are fixed together by adhesive or other fasteners.

[0045] In some optional embodiments, the stepped structure of the side wall 32 can be formed by multiple bending to form a bent structure (not shown in the drawings), and the cover plate 31 is embedded in the bent structure; by using the plasticity of the material of the side wall 32, after the cover plate 31 is placed in the bent structure, the bent structure is pressed by a tool or equipment to completely wrap the cover plate 31. The other end of the side wall 32 is provided with a curled edge structure 322; the main purpose is to form the curled edge structure 322 by stamping to increase the thickness and smoothness of the edge of the side wall 32, thereby avoiding that when the thickness of the plate material of the side wall 32 is relatively low, the user is easily scratched by the edge of the plate material during use.

[0046] Preferably, the curled edge structure 322 of the side wall 32 is curled towards the direction away from the cooking space; the purpose of this arrangement is that during cooking, the water vapor or oil fume formed in the cooking space liquefies on the cover plate 31 and the side wall 32 and flows down through the side wall 32, and the water vapor and oil fume can directly flow into the pot, rather than being accumulated on the curled edge structure 322 which is not easy to clean.

[0047] In this embodiment, the angle α between the line connecting the centroid of the cover plate 31 and the edge of the cover plate 31 and the horizontal line is greater than 16°, so as to prevent the condensed and liquefied water vapor or oil smoke from gathering on the cover plate 31 and dripping into the cooking space. The projection of the shape of the cover plate 31 is close to a rounded rectangle. The angle α is an experimental value obtained through multiple quantitative control experiments. When the angle α is greater than 16°, the number of water droplets dripping from the cover plate 31 begins to turn around. When the angle α is greater than or equal to 20°, there are basically no water droplets that can drip from the cover plate 31. The water droplets on the cover plate 31 basically flow through the lower surface of the cover plate 31 to the edge of the cover plate 31, and then flow through the surface of the side panel 32 to the outside world or the cooking space. In the description of the specification, reference to the terms "one embodiment," "preferably," "example," "specific example," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. The schematic expressions of the above terms in this specification do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any appropriate manner in any one or more embodiments or examples.

[0048] Through the description of the above structure and principle, technical personnel in the relevant technical field should understand that the present invention is not limited to the above specific implementation methods, and improvements and substitutions based on the present invention using the well-known technology in the field all fall within the scope of protection of the present invention and should be defined by the claims.
