[0083] like Figure 1-Figure 2 As shown, the cooking device is provided with a side heating device 410 on the outer peripheral side of the inner pot 10 , and a bottom heating device 420 is provided below the inner pot 10 .

[0084] Optionally, the side heating device 410 is an IH coil or an electric heating coil. The side heating device 410 cooperates with the heat conducting member 200 so that the side wall of the pot body 100 is heated evenly. The bottom heating device 420 is an IH coil or an electric heating coil. The bottom heating device 420 cooperates with the heat conducting member 200 so that the side wall of the pot body 100 has high heat transfer efficiency.

[0085] The following description will be made by taking the side heating device 410 as an IH coil and the bottom heating device 420 as an IH coil as an example.

[0086] like Figure 3 As shown, the inner pot 10 includes an inner pot body 100 , a heat conducting member 200 and a connecting member 300 .

[0087] like Figure 4 As shown, the pot body 100 has a bottom wall 120 and a side wall 110 surrounding the periphery of the bottom wall 120. The bottom wall 120 and the side wall 110 together form a rotating body structure. The bottom wall 120 of the pot body 100 is constructed as a curved surface close to a sphere to facilitate the flow of food in the pot body 100, thereby achieving a better cooking effect.

[0088] Optionally, the outer layer of the pot body 100 is provided with a heating layer. The heating layer has a magnetic conductive material. The magnetic conductive material generates electromagnetic induction with the IH coil and generates heat. Optionally, the magnetic conductive material is a high-efficiency magnetic conductive material or a melt-sprayed magnetic conductive material.

[0089] In some embodiments of the present invention, at least part of the outer wall of the bottom of the pot body 100 is made of a magnetic conductive material to form a fourth heating layer 150. Optionally, the molding material of the outer wall of the pot body 100 includes a magnetic conductive material, that is, the magnetic conductive material is directly used as the outer wall material, which can simplify the molding process of the pot.

[0090] In some embodiments of the utility model, a fourth heating layer 150 containing a magnetic conductive material is provided at the bottom of the pot body 100. Optionally, the magnetic conductive material can be formed on the outer wall of the pot body 100 by processes such as spraying, coating, and plating to form the fourth heating layer 150. Optionally, the magnetic conductive material can be made into a thin sheet or strip-shaped fourth heating layer 150, which is fixed to the outer wall of the pot body 100 by an adhesive or an embedded structure. The fourth heating layer 150 can be flexibly designed and manufactured according to actual needs, so that the pot can adapt to different electromagnetic heating devices and usage environments.

[0091] The fourth heating layer 150 in the above embodiment can generate heat at the bottom of the pot to transfer the heat to the entire pot. Optionally, the bottom heating device 420 is correspondingly arranged at the bottom of the pot body 100. Since the heat is conducted upward from the bottom, the speed of heating food is faster, which can quickly improve the cooking efficiency.

[0092] In some embodiments of the utility model, at least part of the outer wall of the side of the pot body 100 is made of a magnetic conductive material to form a third heating layer 130. Optionally, the molding material of the outer wall of the pot body 100 includes a magnetic conductive material, that is, the magnetic conductive material is directly used as the outer wall material, which can simplify the molding process of the pot. In this embodiment, the third heating layer 130 can generate heat on the side of the pot to transfer heat to the entire pot.

[0093] In some embodiments of the utility model, a third heating layer 130 containing a magnetic conductive material is disposed outside the side wall 110 of the pot body 100. Optionally, the magnetic conductive material can be formed on the outer wall of the pot body 100 by processes such as spraying, coating, and plating to form the third heating layer 130. Optionally, the magnetic conductive material can be made into a thin sheet or strip-shaped third heating layer 130, which is fixed to the outer wall of the pot body 100 by an adhesive or an embedded structure. The third heating layer 130 can be flexibly designed and manufactured according to actual needs, so that the pot can adapt to different electromagnetic heating devices and usage environments.

[0094] The third heating layer 130 in the above embodiment can generate heat at the side of the inner pot to transfer the heat to the entire inner pot. Optionally, the side heating device 410 is correspondingly arranged at the side of the inner pot body 100. Since the heat is conducted inward and downward from the side, the speed of heating food is faster, which can quickly improve the cooking efficiency.

[0095] The inner layer of the pot body 100 is provided with a heat-conducting layer 140. The heat-conducting layer 140 has high heat conduction efficiency and heating uniformity, so that the temperature control of the pot during the cooking process is more accurate. Optionally, the heat-conducting layer 140 is made of aluminum material. Aluminum material has excellent thermal conductivity and a high thermal conductivity coefficient, and can quickly transfer the heat generated by the external heating device to the inside of the pot body 100. This allows the pot to heat up quickly and improve cooking efficiency. In addition, the high heat resistance and corrosion resistance of aluminum material can protect the inner wall of the pot from damage by high temperature and the acidity and alkalinity of food, extend the service life, and reduce the frequency of replacement and maintenance.

[0096] In some embodiments of the present invention, at least part of the inner wall of the pot body 100 is made of aluminum to form the heat conductive layer 140. Optionally, the inner wall of the pot body 100 is made of aluminum, that is, the aluminum material is directly used as the inner wall material, which can simplify the pot molding process.

[0097] In other embodiments of the utility model, a heat-conducting layer 140 including an aluminum material is provided in the pot body 100. Optionally, the aluminum material can be formed on the inner wall of the pot body 100 by a coating, plating or other process to form the heat-conducting layer 140. Optionally, the aluminum material can be made into a thin sheet or a strip-shaped heat-conducting layer 140, which is fixed to the inner wall of the pot body 100 by an adhesive or an embedded structure. The heat-conducting layer 140 can be flexibly designed and manufactured according to actual needs, so that the pot can adapt to different usage environments.

[0098] The side wall 110 of the pot body 100 can be constructed as a columnar straight wall structure, or a curved surface close to a sphere. As can be seen from the above, when the heating device is correspondingly arranged at the bottom of the pot body 100, the heating effect on the side wall 110 is limited. The distance between the side wall 110 and the heating source is far, and the heat needs to be transferred to the side wall 110 through the bottom material. The path is long and the heat transfer efficiency is reduced.

[0099] In the present application, a heat conducting member 200 is provided to improve the heat transfer efficiency of the side wall 110. The heat conducting member 200 is configured as a strip structure, and the heat conducting member 200 extends along the circumference of the pot body 100.

[0100] like Figure 4As shown, the outer wall surface of the pot body 100 is provided with a recessed portion 111 recessed toward the inside of the pot body 100. Optionally, the heat conducting member 200 is mounted to the recessed portion 111. The recessed portions 111 extend continuously along the circumference of the pot body 100 or are arranged at intervals in the circumference.

[0101] Optionally, the recessed portion 111 is at least one of a circular structure, a spiral structure, and a multi-layer structure with upper and lower intervals. In the present utility model, the circular structure means that the recessed portion 111 extends circumferentially around the outer wall of the pot body 100 in a continuous ring shape. The spiral structure means that the recessed portion 111 extends spirally along the height direction DH around the outer wall of the pot body 100. The multi-layer structure with upper and lower intervals means that the recessed portion 111 is a circular structure or a spiral structure, wherein the circular structure or the spiral structure is arranged at intervals of several times along the height direction DH of the pot body 100.

[0102] like Figure 4 As shown, the distance d1 from the wall surface of the recessed portion 111 to the outer wall surface of the pot body 100 is greater than or equal to 0.3 mm, so as to better accommodate the heat conducting member 200 .

[0103] like Figure 2 As shown, the wall thickness d2 of the concave portion 111 is greater than or equal to 0.5 mm. While increasing the contact area between the heat conducting member 200 and the pot body 100 , the strength of the pot body 100 at the concave portion 111 is ensured.

[0104] In the present invention, the heat conducting member 200 is disposed in the recessed portion 111. The heat conducting member 200 is made of a material having a higher thermal conductivity than that of the pot body 100. That is, the heat conducting member 200 is disposed on the side wall 110 of the pot body 100. When the pot body 100 is heated through the bottom, the heat conducting member 200 can quickly conduct the heat of the heat source in the height direction DH, reducing heat loss and making the temperature of each part of the inner pot quickly uniform. This reduces cooking time and allows food to be heated evenly.

[0105] like Figures 5 to 8 As shown, the heat conducting member 200 is constructed as a strip-shaped sheet. The two ends of the heat conducting member 200 are butted together to form a ring structure. The heat conducting member 200 has two surfaces arranged opposite to each other, wherein the first surface has a high flatness and can provide a good contact area; the second surface is provided with a protrusion 210. When the heat conducting member 200 is spliced ​​into a ring shape, the first surface is arranged toward the pot body 100, that is, the first surface of the heat conducting member 200 is in contact with the bottom surface of the recessed portion 111, thereby increasing the contact area between the heat conducting member 200 and the pot body 100 and improving the heat conduction efficiency. At the same time, the stability and tightness of the entire structure are increased, thereby avoiding looseness or instability during use.

[0106] The heat conducting member 200 has a closed cavity 201, and a heat conducting medium is contained in the cavity 201. The heat conducting medium can be a liquid or a gas, and has good heat conducting properties. Optionally, the heat conducting medium is a superconducting liquid.

[0107] The cavity 201 of the heat conducting member 200 extends in a vein-like manner. The vein-like cavity 201 design can increase the contact area between the heat conducting medium and the heat conducting member 200, thereby improving the heat conduction efficiency and allowing the heat to be transferred to the surface of the food more quickly. Through the extension of the vein-like cavity 201, the heat conducting medium can be evenly distributed throughout the cavity 201, thereby achieving uniform heating of the food. In this embodiment, the cavity 201 of the heat conducting member 200 extends along the length direction and the width direction of the heat conducting member 200.

[0108] Optionally, the cavity 201 is formed in the protrusion 210. The contact area between the heat transfer medium and the heat transfer member 200 is increased. Optionally, the protrusion 210 can be set to a corresponding pattern texture, and the shape of the protrusion 210 is not particularly limited. For example, the protrusion 210 can be a regular annular structure with a flat surface, or a grid shape connected to each other, or a honeycomb shape connected to each other.

[0109] Optionally, the heat conducting member 200 is provided with a nozzle 202. The nozzle 202 is used for inflating and filling the heat conducting member 200 with liquid.

[0110] The heat transfer efficiency of the side wall 110 can be improved by disposing the heat conduction member 200. As can be seen from the above, the side wall 110 of the pot body 100 can be constructed as a curved surface close to a sphere. The heat conduction member 200 is far away from the heating source, and the heat transfer efficiency is reduced.

[0111] Optionally, the heat conducting member 200 has a magnetic conductive material. The magnetic conductive material generates electromagnetic induction with the side heating device 410 and generates heat. Optionally, the magnetic conductive material is a high-efficiency magnetic conductive material or a melt-sprayed magnetic conductive material. By providing the magnetic conductive material on the heat conducting member 200 and cooperating with the side heating device 410, the heating source directly heats the heat conducting member 200. The heat conducting member 200 can directly transfer heat to the side wall 110 of the pot body 100, solving the problem that the heat conducting member 200 is far away from the heating source.

[0112] In some embodiments of the present invention, Figures 5 to 8 As shown, at least part of the outer wall (i.e., the second surface) of the heat conducting member 200 is made of a magnetic conductive material to form a first heating layer 220. Optionally, the molding material of the outer wall of the heat conducting member 200 includes a magnetic conductive material, that is, the magnetic conductive material is directly used as the outer wall material, which can simplify the structural design of the pot and reduce the dependence on an additional magnetic conductive layer or coating.

[0113] In some embodiments of the present invention, Figures 5 to 8 As shown, a first heating layer 220 containing a magnetic conductive material is disposed outside the heat conducting member 200. Optionally, the magnetic conductive material may be formed on the outer wall of the heat conducting member 200 by processes such as spraying, coating, and plating to form the first heating layer 220. Optionally, the magnetic conductive material may be made into a thin sheet or strip-shaped first heating layer 220, which is fixed to the second surface of the heat conducting member 200 by an adhesive or an embedded structure. The first heating layer 220 can be flexibly designed and manufactured according to actual needs, so that the pot can adapt to different electromagnetic heating devices and usage environments. As can be seen from the foregoing, a raised portion 210 is formed on the second surface of the heat conducting member 200. As shown in FIG. Figures 7 and 8 As shown, the first heating layer 220 is disposed outside the heat conducting member 200 and can directly cover the raised portion 210 , making the pot core 10 look more beautiful.

[0114] Optionally, the side heating device 410 is located on the side of the pot, and the side heating device 410 is arranged opposite to the first heating layer 220. Heat is directly conducted from the side wall 110 to the pot through the heat conduction member 200, heating food faster and improving cooking efficiency quickly.

[0115] In some embodiments of the utility model, the heat conducting member 200 is welded to the pot body 100. The welding connection can form a solid connection between the heat conducting member 200 and the pot body 100, improve the durability and stability of the product, and avoid loosening or falling off during use. At the same time, the welding connection can make the product appearance more neat and beautiful, without redundant connecting parts or screws, etc., making the pot 10 look more refined and high-end. Specifically, along the height direction DH of the pot 10, the upper side and the lower side of the heat conducting member 200 are respectively welded to the inner wall surface of the recessed portion 111.

[0116] The heat conducting member 200 has a first connecting portion 211 and a second connecting portion 212 that are oppositely disposed.

[0117] In some embodiments of the present invention, the heat conducting member 200 is provided as one. The first connection portion 211 and the second connection portion 212 of the heat conducting member 200 are connected or spaced apart. The two ends of the heat conducting member 200 are opposite to each other, and in the orthographic projection along the height direction DH, the heat conducting member 200 is a circular structure as a whole, so as to be accommodated in the recessed portion 111 provided along the circumference of the pot body 100.

[0118] In other embodiments of the present invention, a plurality of heat-conducting members 200 are provided. The first connection portion 211 of one heat-conducting member 200 is connected to or spaced from the second connection portion 212 of another heat-conducting member 200. The ends of the plurality of heat-conducting members 200 are opposite to each other, and in the orthographic projection along the height direction DH, the heat-conducting members 200 are in a circular structure as a whole, so as to be accommodated in the recessed portion 111 provided along the circumference of the pot body 100.

[0119] In the present invention, the first connection portion 211 and the second connection portion 212 can be connected or spaced apart. Regardless of the form, the docking of the first connection portion 211 and the second connection portion 212 is not affected.

[0120] In some embodiments of the utility model, when the first connection part 211 is connected to the second connection part 212, the connection form is not particularly limited, for example, it can be a lap connection or a snap connection. Exemplarily, the shapes of the first connection part 211 and the second connection part 212 are complementary. For example, the first connection part 211 is provided with a protruding part, and the second connection part 212 is provided with a recessed part, and the protruding part of the first connection part 211 is connected to the recessed part of the second connection part 212. The complementary shapes can ensure a tighter connection between the first connection part 211 and the second connection part 212, thereby increasing the stability of the connection and reducing the risk of loosening or falling off. Exemplarily, the thickness of the first connection part 211 and the second connection part 212 overlapped is consistent with the thickness of the heat conduction member 200. The consistent thickness can simplify the manufacturing process and assembly process, improve production efficiency, reduce processing problems caused by thickness differences, and also help to improve the stability between the first connection part 211 and the second connection part 212, thereby increasing the strength and durability of the overall structure, and at the same time can improve the overall texture and aesthetics of the product appearance.

[0121] On the basis of the above embodiment, the first connection part 211 is connected to the second connection part 212 by welding. The welding connection can form a solid connection between the first connection part 211 and the second connection part 212, improve the durability and stability of the product, and avoid loosening or falling off during use. At the same time, the welding connection can make the product appearance more neat and beautiful, without redundant connection parts or screws, etc., making the pot 10 look more refined and high-end.

[0127] The connecting member 300 covers the edge of the first connecting portion 211 close to the second connecting portion 212, and the connecting member 300 covers the edge of the second connecting portion 212 close to the first connecting portion 211. The connecting member 300 improves the aesthetics and recognition of the pot body 100. In addition, the heat conducting member 200 will expand to different degrees when heated. By covering the first connecting portion 211 and the second connecting portion 212 with the connecting member 300, the firmness of the connection of the heat conducting member 200 is increased, ensuring that the connection will not loosen when heated and expanded.
