[0049] Now, exemplary embodiments according to the present utility model will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in a variety of different forms and should not be interpreted as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present utility model thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art.
[0050] The utility model provides a cooking utensil, which comprises a pot body and a cover body. The pot body has a cylindrical pot inner container. The pot inner container is fixedly arranged at the pot inner container, or can be freely put into or taken out of the pot inner container, so as to facilitate the cleaning of the pot inner container. The pot inner container is usually made of metal material and has a circular opening on the upper surface, which is used to hold materials to be heated, such as rice, soup, etc. The pot body includes a heating device for heating the pot inner container, so as to heat the pot inner container.
[0051] It can be understood that the cooking utensil according to the present invention can be an electric rice cooker, an electric pressure cooker or other cooking utensil, and the cooking utensil can have various functions such as cooking porridge in addition to the function of cooking rice.
[0052] The cover has a shape that is substantially the same as that of the pot body. The cover can be opened and closed on the pot body. Specifically, the cover is pivotally connected to the pot body via a pivot shaft and can freely pivot between a closed position and an open position relative to the pot body around a pivot axis where the pivot shaft is located, so as to facilitate closing and opening the pot body. When the cover is closed on the pot body, it covers the inner pot and forms a cooking space between the inner pot and the inner pot. The cover is usually also provided with a pot mouth sealing ring, which can be made of, for example, a rubber material, and is arranged between the cover and the inner pot to seal the cooking space when the cover is in the closed state.
[0053] It should be noted that the directional terms used herein to describe the various components and parts of the pot body, such as "up", "down", "above", "below", "upward", "downward", "upward", "downward", etc., are relative to the pot body in a horizontal and upright state. If there is no other limitation, the directional terms "inward", "outward", "inwardly", "outwardly", "inside", "outside", etc., in which "inside" refers to the direction close to the center of the pot body, and "outside" refers to the direction away from the center of the pot body.
[0054] like Figure 1 As shown, the inner pot includes an inner pot body 100 and a heat conducting member 200. The inner pot includes a bottom wall and a side wall. The bottom wall, the side wall and the cover body enclose a cooking space, and the upper part of the cooking space is open. The side wall has a depth direction extending from one side of the bottom wall to the open side of the cooking space, and a circumferential direction extending along the circumference of the bottom wall. Figure 2As shown, the outer wall surface of the side wall of the pot body 100 is provided with a recessed portion 110 that is recessed toward the inside of the pot body 100, and the recessed portion 110 extends continuously along the circumference of the pot body 100 or is arranged at intervals in the circumference. The heat conduction member 200 is provided in the recessed portion 110. The heat conduction member 200 has a closed cavity, and the cavity contains a heat-conducting medium. In the utility model, by providing the recessed portion 110 on the outer wall surface of the pot body 100 and arranging the heat conduction member 200 therein, the contact area between the heat conduction member 200 and the pot body 100 can be increased, thereby improving the heat conduction efficiency, and at the same time, strengthening the overall structural strength between the heat conduction member and the pot body. The heat conduction member 200 is provided outside the pot body 100 to avoid possible leakage and other phenomena that may cause contamination to food. The recessed portion 110 extends along the circumference of the pot body 100, so that the heat conducting member 200 can be more evenly distributed on the surface of the pot. When in use, the heat heated by the inner pot can be quickly conducted to the side of the inner pot through the heat conducting medium, so that the inner pot is heated evenly, thereby achieving even heating of the food. This solution does not require additional heating sources, so the production cost is reduced. In the utility model, the pot body 100 and the heat conducting member 200 can be produced separately.
[0055] In some embodiments of the utility model, the height of the recessed portion 110 accounts for 10 to 80% of the total height of the pot body 100. Exemplarily, the recessed portion 110 is arranged in the middle position of the pot body 100 along its height direction DH. The recessed portion 110 is arranged in the middle position of the pot body 100, that is, the heat conduction member 200 is arranged in the middle position of the pot body 100, which improves the heat transfer efficiency of the side wall of the pot body 100 along the height direction DH, and can make the heat more evenly distributed in the height direction DH of the entire pot, so as to achieve uniform heating of the food and avoid the situation where the local temperature is too high or too low. Exemplarily, the recessed portion 110 is constructed as a circular ring structure.
[0056] In some embodiments of the present invention, the recessed portion 110 is at least one of a circular structure, a spiral structure, and a multi-layer structure with upper and lower intervals. In the present invention, the circular structure means that the recessed portion 110 extends circumferentially around the outer wall of the pot body 100 in a continuous ring shape. The spiral structure means that the recessed portion 110 extends spirally along the height direction around the outer wall of the pot body 100. The multi-layer structure with upper and lower intervals means that the recessed portion 110 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 of the pot body 100.
[0057] like Figure 1As shown, in some embodiments of the present invention, the height difference between the outer surface of the heat-conducting member 200 and the outer surface of the pot body 100 is less than or equal to 2 mm. Exemplarily, the connection between the heat-conducting member 200 and the pot body 100 is flush. The overall appearance of the pot body 100 is made neater and more uniform, and the connection between the heat-conducting member 200 and the pot body 100 is a relatively flat surface, thereby improving the aesthetics of the product. Exemplarily, along the radial direction of the pot body 100, the thickness of the edge of the heat-conducting member 200 is consistent with the depth of the recessed portion 110. When the heat-conducting member 200 is installed in the recessed portion 110, the edge of the heat-conducting member 200 and the pot body 100 can be better integrated, which can make the pot look more refined and upscale.
[0058] In some embodiments of the present invention, the wall thickness of the recessed portion 110 is greater than or equal to 0.3 mm, which increases the contact area between the heat conducting member 200 and the pot body 100 while ensuring the strength of the pot body 100 at the recessed portion 100 .
[0059] 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 connection parts or screws, etc., making the pot look more refined and high-end.
[0060] The specific implementation of the heat conduction element 200 is introduced below.
[0061] In some embodiments of the present invention, the cavity of the heat conducting member 200 extends in a vein-like manner. The vein-like cavity 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 food surface more quickly. Through the vein-like extension of the cavity, the heat conducting medium can be evenly distributed throughout the cavity, thereby achieving uniform heating of the food. In this embodiment, the cavity of the heat conducting member 200 extends along the length direction and the width direction of the heat conducting member 200.
[0062] like Figure 3As shown, in the present invention, the heat conducting member 200 is constructed as a sheet plate. The two ends of the heat conducting member 200 are butt-jointed 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, 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 110, 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. Optionally, the heat conducting member 200 or the protrusion 210 in the heat conducting member 200 can be subjected to anti-rust treatment such as electroplating and painting to extend the service life and enhance the aesthetics.
[0063] In some embodiments of the present invention, the cavity 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.
[0064] For example, the cavity can be formed by the following steps: either end of the heat conducting member 200 is opened, and high pressure gas is blown at the opening to expand the inside of the sheet to form a receiving cavity for containing the heat conducting medium. Once the receiving cavity is formed, the heat conducting medium can be filled into the cavity by an appropriate method. The heat conducting medium can be a liquid or a gas with good heat conducting properties.
[0065] In some embodiments of the utility model, the heat conducting medium is a superconducting liquid, which is injected after a vacuum environment is formed in the cavity. Injection in a vacuum environment can ensure that the superconducting liquid fully fills every corner of the accommodating cavity, ensuring the best filling effect, thereby improving the heat conduction efficiency of the entire system. Without the intervention of air or other gases, thermal resistance can be reduced, allowing the superconducting liquid to transfer heat more effectively. The vacuum environment can prevent the superconducting liquid from reacting with oxygen in the air, thereby avoiding possible oxidation or corrosion problems and extending the service life of the heat conducting member 200.
[0066] In some embodiments of the present invention, the heat conducting member 200 further includes a circumferential portion 220, which is disposed around the outer periphery of the protruding portion 210. As described above, the protruding portion 210 is used to accommodate the heat conducting medium, and the circumferential portion 220 is disposed around the outer periphery of the protruding portion 210, and is used to connect with the groove wall of the recessed portion 110 of the pot body 100. The provision of the circumferential portion 220 can also play a protective role on the protruding portion 210.
[0067] In some embodiments of the utility model, along the thickness direction of the heat conducting member 200, the thickness of the circumferential portion 220 is less than the thickness of the protruding portion 210. The thinner circumferential portion 220 can improve the flexibility and plasticity of the heat conducting member 200. The circumferential portion 220 is flush with the connection between the pot body 100. The overall appearance of the pot body 100 is made neater and more uniform. Exemplarily, along the radial direction of the pot body 100, the thickness of the circumferential portion 220 is consistent with the depth of the recessed portion 110.
[0068] In some embodiments of the utility model, the protrusion 210 is provided with a groove 230, and the groove 230 is recessed inward from the surface of the protrusion 210. The shape of the groove 230 is not particularly limited, for example, it can be one or a combination of a circle, a triangle, a quadrilateral, a rhombus or a hexagon. Grooves 230 of different shapes can give the product more design elements and aesthetics. By setting the groove 230, the bending and compression resistance of the heat conduction member 200 can be improved, thereby improving the mechanical strength. The groove 230 can also disperse stress and help reduce the stress concentration phenomenon generated by the heat conduction member 200 during use.
[0069] In some embodiments of the present invention, the sidewall of the groove 230 gradually expands from the bottom to the opening, thereby further reducing the stress concentration phenomenon and improving the pressure resistance of the heat conduction element 200 .
[0070] In some embodiments of the present invention, the distribution form of the grooves 230 is not particularly limited, for example, multiple grooves 230 may be spaced apart, or multiple grooves 230 may be distributed in a scattered point shape and / or array shape, thereby increasing the bearing capacity of the material, improving the bending and compression resistance, and thus improving the mechanical strength.
[0071] In some embodiments of the present invention, the heat conducting member 200 is provided with a first connecting portion 241 and a second connecting portion 242 at both ends along the length direction, and the first connecting portion 241 and the second connecting portion 242 are butted together to form a ring. By adopting the design of butting both ends to form a ring, the manufacturing process and assembly process can be simplified, and the production efficiency can be improved.
[0072] In some embodiments of the present invention, the connection form between the first connection part 241 and the second connection part 242 is not particularly limited, for example, it can be a lap connection or a snap connection. Exemplarily, the shapes of the first connection part 241 and the second connection part 242 are complementary. For example, the first connection part 241 is provided with a protruding part, and the second connection part 242 is provided with a recessed part, and the protruding part of the first connection part 241 is connected to the recessed part of the second connection part 242. The complementary shapes can ensure a tighter connection between the first connection part 241 and the second connection part 242, thereby increasing the stability of the connection and reducing the risk of loosening or falling off. Exemplarily, the thickness of the first connection part 241 and the second connection part 242 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 241 and the second connection part 242, 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.
[0073] In some embodiments of the utility model, the first connection part 241 is connected to the second connection part 242 by welding. The welding connection can form a solid connection between the first connection part 241 and the second connection part 242, 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 look more refined and high-end.
