Description

A cooking utensil Technical Field

[0001] This utility model belongs to the field of kitchen appliance technology, specifically relating to a cooking utensil. Background Technology

[0002] Most common clay pot cooking appliances use a heating plate for heating. The appliance includes a heat-insulating cover inside the pot body, with the heating plate located inside the cover. The heat-insulating cover forms a cavity for the inner pot. It is usually made of metal to concentrate heat within the cavity, preventing excessive heat loss and improving heat utilization and heating efficiency. The inner pot is placed on the heating plate, allowing heat transfer between them and providing upward support.

[0003] The heating plate typically has a protruding fixing post at its bottom, which securely connects it to the bottom wall of the insulation cover. When the inner liner presses down on the heating plate under gravity, the force is transmitted through the fixing post to the connection point between the insulation cover and the fixing post. Especially during transportation, when the inner liner is placed inside the cavity enclosed by the insulation cover, bumps or shaking can cause the inner liner to impact the heating plate. This impact force is also transmitted through the fixing post to the connection point between the insulation cover and the fixing post, and the surrounding area is prone to stress concentration, leading to deformation or damage. Once this area of ​​the insulation cover deforms, the position of the heating plate will change (e.g., the heating plate will move downwards or tilt), affecting the stability of the heating plate in supporting the inner liner. Simultaneously, it reduces the adhesion between the heating plate surface and the inner liner, impacting the heating effect. Summary of the Invention

[0004] This utility model provides a cooking appliance to solve the problem that stress concentration easily occurs at the connection between the heating plate and the heat preservation cover, causing deformation of the heat preservation cover and affecting the structural stability of the heat preservation cover and the positional stability of the heating plate.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A cooking appliance includes a pot body and an inner pot. The pot body includes an outer cover and a heat-insulating cover placed inside the outer cover. A heating plate is disposed inside the heat-insulating cover. The inner pot is placed on the heating plate. A fixing post protrudes from the bottom of the heating plate. The fixing post is fixedly connected to the bottom wall of the heat-insulating cover. A support member is also disposed between the outer cover and the bottom wall of the heat-insulating cover. The support member abuts against the bottom wall of the heat-insulating cover. The support member and the fixing post are arranged vertically and vertically respectively.

[0007] In this invention, the heating plate is fixedly connected to the bottom wall of the insulation cover via a fixing post. Meanwhile, there are gaps between other areas of the heating plate and the bottom wall of the insulation cover. Therefore, when the heating plate is subjected to downward pressure from the inner liner, the force is transmitted to the insulation cover through the fixing post. Thus, the stress concentration point on the bottom wall of the insulation cover is located at its connection point with the fixing post. Furthermore, a support member is provided between the outer cover and the bottom wall of the insulation cover. This support member is vertically aligned with the fixing post and abuts against the bottom wall of the insulation cover, providing upward support at the connection point. The supporting force and the force transmitted from the fixing post to the insulation cover are collinear and opposite. This improves the structural strength of a local area of ​​the insulation cover (the area connected to the fixing post) and also offsets some of the downward pressure on that area, making it less prone to deformation or damage, thereby increasing the structural strength of the insulation cover. It also ensures the positional stability of the heating plate, preventing it from shifting or tilting, thus ensuring a good fit with the inner liner and guaranteeing effective heating.

[0008] The projection of the fixed column toward the bottom wall of the insulation cover forms the connection area, and at least a portion of the support abuts against the connection area.

[0009] In this solution, the fixed column contacts the insulation cover, and the area covered by the fixed column constitutes the connection area. The downward pressure of the heating plate is transmitted to the connection area, and at least part of the support abuts against the connection area, which can correspondingly offset the force of the fixed column on the connection area and reduce the risk of deformation of the connection area.

[0010] The support member includes a support portion having a first support area and a second support area, the first support area abutting against the connecting area, and the second support area abutting against the outer periphery of the connecting area.

[0011] In this design, the first support area of ​​the support unit abuts against the connecting area, and the second support area abuts against the area on the outer periphery of the connecting area. Therefore, the support unit can not only support the connecting area, but also support the area around the connecting area, thereby enabling the support unit to support a larger area. This not only effectively avoids deformation of the connecting area, but also prevents deformation of the area outside the connecting area, thus improving the overall strength of the bottom wall of the insulation cover.

[0012] The bottom wall of the heat insulation cover is provided with an upward protrusion. The protrusion forms a mating boss on the side facing the heating plate and a mating groove on the side away from the heating plate. The fixing column is fixed to the mating boss and the support member abuts in the mating groove.

[0013] In this design, the bottom of the insulation cover is partially raised, and it is fixedly connected to the fixing column via a mating boss. The raised portion is bent and raised relative to the bottom of the insulation cover, which improves the strength of the bottom wall of the insulation cover. At the same time, the mating boss brings its mounting surface closer to the fixing column, making it easier to fix and connect with the fixing column. In addition, the mating groove on the lower side of the raised portion not only positions the support component, making it more accurately abut against the connection area, but also limits the support component. The groove wall can confine the support component inside the groove, allowing the support component to stably abut against the top wall of the groove.

[0014] The bottom wall of the heat preservation cover has a fixing hole. The cooking appliance also includes a connector. The connector passes through the fixing hole and is fastened to the fixing post. The support has a support part with a support rib around the outer periphery of the connector so that the support rib forms a cavity for accommodating the connector.

[0015] In this design, the connection between the fixing column and the insulation cover is achieved using screws and other connectors, ensuring strong connection stability. Furthermore, the pre-tightening force of the connectors enhances the structural strength of the connection between the insulation cover and the fixing column, allowing it to withstand greater downward pressure without damage. The supporting ribs surrounding the connectors not only create a cavity that accommodates at least a portion of the connector, preventing interference between the support and the connector, but also provide uniform support to the outer periphery of the connector, preventing localized sagging of the insulation cover and thus avoiding tilting of the heating plate.

[0016] The width of the support gradually decreases from top to bottom, while the thickness of the support ribs gradually increases from top to bottom.

[0017] In this design, the support structure experiences stress at the top and transmits it downwards. The support structure's width gradually decreases from top to bottom, which enhances its structural strength, enabling it to withstand greater downward pressure without damage. Furthermore, the thickness of the support ribs gradually increases downwards, further increasing the structural strength of the support structure, resulting in greater strength towards the bottom.

[0018] The outer cover includes a base located below the insulation cover and a surrounding wall around the outer perimeter of the insulation cover. The base is provided with a mounting groove, and the support is located in the mounting groove.

[0019] In this design, the mounting groove serves to position the support components, reducing assembly difficulty and improving their positional accuracy. Furthermore, when the support component is subjected to downward pressure from the insulation cover, the groove wall provides lateral restraint, ensuring the support component remains vertically aligned with the fixed column and preventing lateral displacement under stress.

[0020] The support includes a support portion and a mounting portion located below the support portion. The width of the support portion is greater than the width of the mounting portion to form a stepped surface between the support portion and the mounting portion. The mounting portion is located in a mounting groove, and the stepped surface abuts against the top of the groove wall of the mounting groove.

[0021] In this design, the mounting part is inserted into the mounting groove, so that the top of the mounting groove abuts against the stepped surface between the support part and the mounting part, which facilitates the installation of the support. When the support is subjected to force, the force is transmitted to the groove wall of the mounting groove through the stepped surface, and the force is distributed to the base through the groove wall of the mounting groove.

[0022] The base is provided with upward-extending mating ribs, which form an installation groove.

[0023] In this design, the mounting groove is formed by the upward-protruding ribs of the base. This brings the mounting groove closer to the insulation cover, effectively shortening the length of the support component and improving its structural strength, preventing breakage under stress due to its large length. Furthermore, the ribs allow the mounting groove to be formed on both flat and uneven surfaces of the base while maintaining a level opening, thus increasing the flexibility of its placement.

[0024] The side wall of the heat insulation cover is provided with an inwardly contracting section and a vertical section located below the inwardly contracting section. The horizontal projection of the inwardly contracting section is located on the heating plate.

[0025] In this design, an inward-curving section is incorporated at the bottom of the sidewall of the insulation cover, which enhances the strength of the bottom of the sidewall and reduces the likelihood of deformation. The vertical section increases the height of the insulation cover, allowing the heating plate to be positioned lower. Simultaneously, the inner pot, placed on the heating plate, is also positioned lower, reducing the overall height of the cooking appliance. This allows more of the inner pot to be accommodated within the insulation cover, improving heat retention. Attached Figure Description

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0044] As shown in Figures 1, 3, and 4, a cooking appliance includes a pot body 1 and an inner pot 3. The pot body 1 includes an outer cover 11 and a heat preservation cover 12 placed inside the outer cover 11. A heating plate 2 is provided inside the heat preservation cover 12. The inner pot 3 is placed on the heating plate 2. A fixing post 21 is protruding from the bottom of the heating plate 2. The fixing post 21 is fixedly connected to the bottom wall of the heat preservation cover 12. A support member 4 is also provided between the bottom wall of the outer cover 11 and the bottom wall of the heat preservation cover 12. The support member 4 abuts against the bottom wall of the heat preservation cover 12. The support member 4 and the fixing post 21 are arranged vertically and vertically respectively.

[0045] It should be noted that in this utility model, the support member 4 and the fixing column 21 are vertically aligned. As long as the projection of the fixing column 21 toward the bottom wall of the heat insulation cover 12 is at least partially overlapping with the projection of the support member 4 toward the bottom wall of the heat insulation cover 12, the support member 4 and the fixing column 21 do not need to be completely coaxial.

[0046] Preferably, the heat insulation cover 12 is made of metal, and the support member 4 is made of high temperature resistant material or heat insulation material, so as to reduce the heat transfer from the heat insulation cover 12 to the outer cover 11 through the support member 4 and prevent the outer cover 11 from deforming at high temperature.

[0047] Preferably, as shown in Figure 3, the inner liner 3 has a flange at its rim, wherein there is a vertical gap between the flange and the rim of the heat insulation cover 12, so that the inner liner 3 is completely placed on the heating plate 2 and supported by the heating plate 2.

[0048] In this invention, the heating plate 2 is fixedly connected to the bottom wall of the heat insulation cover 12 via the fixing column 21. At the same time, there is a gap between other areas of the heating plate 2 and the bottom wall of the heat insulation cover 12. Therefore, when the heating plate 2 is subjected to the downward pressure of the inner liner 3, it will transmit the force to the heat insulation cover 12 through the fixing column 21. Thus, the force concentration point of the bottom wall of the heat insulation cover 12 is located at the connection position with the fixing column 21. Meanwhile, in this invention, a support member 4 is also provided between the bottom wall of the outer cover 11 and the heat insulation cover 12. The support member 4 is arranged vertically and vertically corresponding to the fixing column 21 and abuts against the bottom wall of the heat insulation cover 12, thereby providing upward support for the connection position between the heat insulation cover 12 and the fixing column 21. The supporting force and the force transmitted from the fixing column 21 to the heat insulation cover 12 are collinear and opposite. On the one hand, this can improve the structural strength of a local area of ​​the heat insulation cover 12 (the area 123 connected to the fixing column 21), and on the other hand, it can offset part of the downward pressure on this area, making it more difficult for this area to deform or be damaged, thereby improving the structural strength of the heat insulation cover 12. At the same time, it also ensures the positional stability of the heating plate 2, making it less likely to move or tilt, thereby ensuring a good fit with the inner liner 3 and ensuring the heating effect.

[0049] Preferably, as shown in Figure 5, the bottom of the heating plate 2 is provided with multiple fixing posts 21 to form multiple fixation points with the bottom wall of the heat insulation cover 12, and the support member 4 is provided in a one-to-one correspondence with the fixing posts 21.

[0050] As a preferred embodiment of the present invention, as shown in Figures 2 and 4, the projection of the fixed column 21 toward the bottom wall of the heat insulation cover 12 forms a connecting area 123, and at least a portion of the support member 4 abuts against the connecting area 123.

[0051] The fixing column 21 contacts the heat insulation cover 12, and the area covered by the fixing column 21 constitutes the connection area 123. The downward pressure of the heating plate 2 is transmitted to the connection area 123. At least part of the support member 4 abuts against the connection area 123, which can correspondingly offset the force of the fixing column 21 on the connection area 123 and reduce the risk of deformation of the connection area 123.

[0052] In one embodiment, the support member 4 is completely abutted against the connection area 123, that is, the projection of the support member 4 toward the bottom wall of the insulation cover 12 is completely covered by the projection of the fixing column 21 toward the bottom wall of the insulation cover 12, so as to improve the support effect of the support member 4 on the connection area 123.

[0053] In another embodiment, as shown in FIG2, the support member 4 includes a support portion 41, the support portion 41 having a first support region 412 and a second support region 413, the first support region 412 abutting against the connecting region 123, and the second support region 413 abutting against the outer periphery of the connecting region 123.

[0054] The first support area 412 of the support part 41 abuts against the connecting area 123, and the second support area 413 abuts against the area on the outer periphery of the connecting area 123. Therefore, the support part 41 can not only support the connecting area 123, but also support the area around the connecting area 123. This allows the support part 41 to support a larger area, effectively preventing deformation of the connecting area 123 and also preventing deformation of the outer area of ​​the connecting area 123, thereby improving the overall strength of the bottom wall of the insulation cover 12.

[0055] Preferably, as shown in Figures 4 and 6, the bottom wall of the heat insulation cover 12 is provided with an upwardly protruding bulge 126. The bulge 126 forms a mating boss 121 on the side facing the heating plate 2 and a mating groove 122 on the side away from the heating plate 2. The fixing post 21 is fixed to the mating boss 121 and the support member 4 abuts against the mating groove 122.

[0056] In this embodiment, the fixing post 21 abuts against the platform of the mating boss 121, so that a part of the platform of the mating boss 121 constitutes the connecting area 123, the top wall of the mating groove 122 is the platform of the mating boss 121, and the support member 4 abuts against the top wall of the mating groove 122.

[0057] The bottom of the insulation cover 12 has a partial bulge, which is fixedly connected to the fixing post 21 via a mating boss 121. The bulge 126 is bent and raised relative to the bottom of the insulation cover 12, increasing the strength of the bottom wall of the insulation cover 12. At the same time, the mating boss 121 brings its mounting surface closer to the fixing post 21, making it easier to fix and connect with the fixing post 21. In addition, the mating groove 122 on the lower side of the bulge 126 not only positions the support member 4, making it more accurately abut against the connection area 123, but also limits the support part 41. The groove wall of the mating groove 122 can confine the support member 4 inside the mating groove 122, so that the support part 41 can stably abut against the top wall of the mating groove 122.

[0058] This utility model does not limit the connection method between the fixing column 21 and the heat preservation cover 12. In a preferred embodiment, as shown in FIG4, the bottom wall of the heat preservation cover 12 is provided with a fixing hole. The cooking appliance also includes a connector 5. The connector 5 passes through the fixing hole and is fastened to the fixing column 21. The support member 4 has a support part 41. The support part 41 has a support rib 411 surrounding the outer periphery of the connector 5, so that the support rib 411 forms a cavity 414 for accommodating the connector 5.

[0059] The connection between the fixing column 21 and the insulation cover 12 is achieved through screws or other connectors 5, ensuring strong connection stability. Furthermore, the pre-tightening force of the connectors 5 enhances the structural strength of the connection between the insulation cover 12 and the fixing column 21, enabling it to withstand greater downward pressure without damage. The supporting ribs 411 surrounding the connectors 5 not only form a cavity 414 that can accommodate at least a portion of the connectors 5, preventing interference between the support ribs 4 and the connectors 5, but also provide uniform support to the outer periphery of the connectors 5, preventing localized sagging of the insulation cover 12 and thus avoiding tilting of the heating plate 2.

[0060] In a preferred embodiment, as shown in FIG4, the width of the support portion 41 gradually decreases from top to bottom, and the thickness of the support rib 411 gradually increases from top to bottom.

[0061] The support portion 41 is subjected to force at the top and transmitted downwards. The support portion 41 has a structure where its width gradually decreases from top to bottom, which increases its structural strength, enabling it to withstand greater downward pressure without damage. Furthermore, the thickness of the support ribs 411 gradually increases downwards, further enhancing the structural strength of the support portion 41, making it stronger towards the bottom.

[0062] Preferably, as shown in Figures 4 and 5, the outer cover 11 includes a base 111 located below the heat insulation cover 12 and a surrounding wall 112 surrounding the outer periphery of the heat insulation cover 12. The base 111 is provided with a mounting groove 114, and the support member 4 is disposed in the mounting groove 114.

[0063] The mounting groove 114 can position the support member 4 during installation, reducing assembly difficulty and improving the positional accuracy of the support member 4. In addition, when the support member 4 is subjected to downward pressure from the insulation cover 12, the groove wall of the mounting groove 114 can also provide lateral restraint for the support member 4, ensuring that the support member 4 always maintains a vertically corresponding position with the fixed column 21, and preventing the support member 4 from shifting laterally under force.

[0064] It should be noted that this embodiment does not limit the assembly method of the enclosure 112 and the base 111. In one embodiment, the base 111 and the enclosure 112 are integrally formed, so that the outer cover 11 is an integral structure. In another embodiment, the base 111 and the enclosure 112 are separate structures, which are assembled into a complete outer cover 11 through subsequent assembly.

[0065] This embodiment does not limit the fixing method of the support member 4 and the base 111. Preferably, the support member 4 is inserted and fixed into the mounting groove 114. Furthermore, after the two are inserted, there is a gap between the bottom of the support member 4 and the bottom wall of the mounting groove 114. Of course, the support member 4 can also be fixed to the base 111 in other ways, such as screw connection, snap-fit ​​connection, etc., which is not limited here.

[0066] Further, as shown in FIG4, the support member 4 includes a support portion 41 and a mounting portion 42 located below the support portion 41. The width of the support portion 41 is greater than the width of the mounting portion 42, so as to form a stepped surface 43 between the support portion 41 and the mounting portion 42. The mounting portion 42 is located in the mounting groove 114, and the stepped surface 43 abuts against the top of the groove wall of the mounting groove 114.

[0067] The mounting part 42 is inserted into the mounting groove 114, so that the top of the mounting groove 114 abuts against the step surface 43 between the support part 41 and the mounting part 42, which facilitates the installation of the support member 4. When the support member 4 is subjected to force, it is transmitted to the groove wall of the mounting groove 114 through the step surface 43, so that the force is distributed to the base 111 through the groove wall of the mounting groove 114.

[0068] In one embodiment, the bottom wall of the base 111 is partially recessed to form a mounting groove 114. Preferably, as shown in Figures 4 and 5, the base 111 is provided with an upwardly extending mating rib 113, which surrounds the mounting groove 114.

[0069] The mounting groove 114 is formed by the protruding ribs 113 extending upward from the base 111. On the one hand, this brings the mounting groove 114 closer to the insulation cover 12, effectively shortening the length of the support member 4 and improving its structural strength, preventing breakage under stress due to its large length. On the other hand, the mounting groove 114 formed by the ribs 113 can be formed on either the flat surface of the base 111 or on its uneven surface, while maintaining a horizontal groove opening, thus improving the flexibility of its placement.

[0070] Specifically, as shown in Figure 4, the bottom wall of the base 111 has a first platform and a second platform, wherein the first platform is lower than the second platform. Both the first platform and the second platform are provided with mating ribs 113. The upward extension height of each mating rib 113 is different (the extension height of the mating rib 113 on the second platform is smaller, and the extension height of the mating rib 113 on the first platform is larger). However, the tops of each mating rib 113 are flush so that the opening of the mounting groove 114 is horizontal.

[0071] Preferably, as shown in Figures 3 and 6, the side wall of the heat insulation cover 12 is provided with an inwardly contracting portion 124 and a vertical section 125 located below the inwardly contracting portion 124, and the horizontal projection of the inwardly contracting portion 124 is located on the heating plate 2.

[0072] An inwardly recessed portion 124 is provided at the bottom of the side wall of the heat insulation cover 12, which can improve the strength of the bottom of the side wall of the heat insulation cover 12 and reduce the possibility of deformation of the heat insulation cover 12. The vertical section 125 increases the height of the heat insulation cover 12, thereby allowing the heating plate 2 to be positioned lower. At the same time, the inner pot 3 is also positioned lower after being placed on the heating plate 2, thereby reducing the overall height of the cooking appliance and allowing more of the inner pot 3 to be accommodated inside the heat insulation cover 12 in the height direction, thus improving the heat preservation effect.

[0073] For any parts not mentioned in this utility model, existing technologies can be used or referenced.

[0074] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0075] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
