Description

Technical Field

[0001] The utility model relates to the technical field of cooking utensils, in particular to an inner pot and a cooking utensil. Background Art

[0002] At present, some cooking utensils have inner pots that are equipped with heat transfer liquid heat conduction rings or superconducting rings on the outside to speed up heat transfer and increase the speed of heat transfer from the bottom of the pot to the pot wall. However, due to the need for a certain space for the heat transfer liquid flow path and the need for heat transfer area, it is difficult to avoid the heat conduction ring or superconducting ring having surface textures. The presence of such textures causes the outer surface of the inner pot to have significant separations and poor coordination. In addition, the presence of such textures makes it difficult to perform surface treatment procedures on the inner pot as a whole. The inner pot body and the heat conduction ring need to be treated separately before assembly, which is costly.

[0048] Now, exemplary embodiments according to the present invention will be described in more detail with reference to the accompanying drawings.

[0049] The present application provides a cooking utensil, which comprises a cover and a pot body. The cover has a shape substantially corresponding to the pot body. The cover can be arranged on the pot body in an openable and closable manner. The cover can be pivotally connected to the pot body through a pivot shaft, for example, 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 of the pot body.

[0050] The pot body includes an inner pot 100 and has a cylindrical inner pot storage portion. The inner pot 100 can be freely placed in or taken out of the inner pot storage portion to facilitate cleaning of the inner pot 100. The inner pot 100 is usually made of a metal material and has a circular opening on the upper surface for holding materials to be heated, such as rice, soup, etc.

[0051] The pot body includes a heating device for heating the inner pot 100, so as to heat the inner pot 100. The heating device is arranged below the inner pot 100. The heating device can be a device such as a coil disk.

[0052] When the cover is closed on the pot body, it covers the inner pot 100 and forms a cooking space between the cover and the inner pot 100. The cover is usually provided with a pot mouth sealing ring, which can be made of, for example, rubber material, and is arranged between the cover and the inner pot 100 to seal the cooking space when the cover is in the closed state.

[0053] It can be understood that the cooking utensil according to the present application 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.

[0054] It should be noted that the directional terms used herein to describe the various components, parts, etc. of the cooking appliance, such as "up", "down", "above", "below", "upward", "downward", "upward", "downward", etc., are relative to the cooking appliance in a horizontal and upright state. If there is no other qualification, the directional terms "inward", "outward", "inwardly", "outwardly", "inside", "outside", etc., in which "inside" refers to the direction close to the center of the cooking appliance, and "outside" refers to the direction away from the center of the cooking appliance.

[0055] Among them, the inner pot 100 of the present application refers to Figures 1 to 6 The inner pot 100 includes a pot body 104 and a heat-conducting ring 110 / 210. A groove 103 is provided on the periphery of the pot body 104. The heat-conducting ring 110 is provided in the groove 103. The heat-conducting ring 110 / 210 has a ring body 111, and a liquid channel 112 is provided in the ring body 111. The liquid channel 112 is filled with heat-conducting liquid, and the liquid channel 112 forms a concave-convex pattern 113 on at least one surface of the ring body 111. The outer surface of the heat-conducting ring 110 / 210 is configured as a smooth surface. The heat-conducting liquid can be a liquid with high heat-conducting efficiency such as a superconducting liquid.

[0056] According to the inner pot of the utility model, the overall coordination of the outer surface of the inner pot is improved, and the user experience is improved; and the overall setting of the outer surface allows the heat-conducting ring to be subjected to surface treatment processes such as anti-oxidation treatment together with the pot body, which significantly reduces the cost compared to the pot body and the heat-conducting ring being treated separately and then assembled.

[0057] Specifically, refer to Figure 1 and Figure 2 The pot body 104 includes a pot bottom 101 and a pot wall 102, wherein the pot wall 102 is connected to the upper side of the pot bottom 101, and the groove 103 is located in the pot wall 102. The pot bottom 101 is used for heating, for example, the pot bottom 101 can be directly heated by the above-mentioned heating device. As an optional embodiment, the distance between the bottom end of the groove 103 and the pot bottom 101 is less than 60 mm.

[0058] Exemplarily, the bottom end of the groove 103 is located at the connection between the pot bottom 101 and the pot wall 102, so that the heat conductive ring 110 is connected to the pot bottom 101, preferably directly connected. In this way, the heat conductive ring 110 / 210 can quickly conduct heat upward from the pot bottom 101. The connection point can refer to the arc transition surface between the pot wall of the flat bottom pot and the flat pot bottom, and can also refer to the R angle transition between the pot wall of the round bottom pot and the arc pot bottom.

[0059] The ring body 111 is arranged around the pot body 104 and connected end to end through the interface 114 to form a ring. For example, during manufacturing, the ring body 111 is originally configured as a long strip, and its two ends are configured as interface parts 114. After being arranged around the outer periphery of the groove 103, the two interface parts 114 are connected to form a continuous ring.

[0060] As an optional embodiment, the heat-conducting ring 110 / 210 has a certain thickness, which protrudes from the outer surface of the pot body 104, so that the heat-conducting ring 110 and the pot body 104 form a step-type structure. Preferably, the step structure is constructed as a rounded structure. In other words, the R angle transition between the heat-conducting ring 110 / 210 and the pot body 104 further forms a smooth integral outer surface. As another implementation form, the heat-conducting ring 110 is flush with the outer surface of the pot body 104 or transitions smoothly, so that the pot body 104 and the heat-conducting ring 110 are easier to be seen as a whole, thereby improving the visual effect. In addition, the overall smooth surface is also conducive to taking the inner pot from the pot body without bumping due to the presence of steps.

[0061] like Figure 2 As shown, the depth D1 of the groove 103 is greater than or equal to 0.3 mm, and the thickness D2 of the pot body 104 at the groove 103 is greater than or equal to 0.5 mm. Thus, sufficient installation space for the heat-conducting ring 110 is provided while maintaining sufficient strength of the pot wall.

[0062] Continue to refer Figure 1As an implementation form, the heat-conducting ring 110 / 210 further includes a fixing plate 115, which is arranged on the outside of the ring body 111 and located at the interface portion 114. The fixing plate 115 can be fixedly connected to the pot body 104, or to the ring body 111, or to both the pot body 104 and the ring body 111. The fixing plate 115 can be arranged by welding, bonding, etc. Figure 1 In the illustrated embodiment, the fixing sheet 115 is fixed to the pot body 104 and / or the ring body 111 by a connecting member 117 such as a screw. Thus, the fixing sheet 115 not only strengthens the assembly firmness between the heat-conducting ring 110 / 210 and the pot body 104, but also shields the interface 114, further improving the coordination of the outer surface of the inner pot 100.

[0063] As an optional implementation, refer to Figure 3 and Figure 4 , the liquid channel 112 of the heat-conducting ring 110 forms a concavo-convex pattern 113 on the inner surface of the ring body 111, and the outer surface of the heat-conducting ring 110 is configured as a smooth surface. That is, the concavo-convex pattern 113 is formed on only one side of the ring body 111, and the concavo-convex pattern 113 is arranged inwardly around the groove 103 during assembly. According to the above scheme, the concavo-convex pattern 113 is hidden inside, and the outer surface of the inner pot 100 with good integrity can be obtained in a relatively low-cost manner. Preferably, in this embodiment, a protective layer is attached to the outer side of the pot body 104 and the heat-conducting ring 110. Thereby, the integrity and coordination of the inner pot 100 are further improved. Exemplarily, the protective layer can be a polytetrafluoroethylene layer.

[0064] As another embodiment, refer to Figure 5 and Figure 6 , the liquid channel 112 of the heat-conducting ring 210 forms a concave-convex pattern 113 on the outer surface of the ring body 111. In addition, a shielding layer 216 is provided on the outer surface of the ring body 111, and the outer surface of the shielding layer 216 is configured as a smooth surface, thereby shielding the pattern on the outer surface of the ring body 111 so that the outer surface of the heat-conducting ring 110 forms a smooth surface. In this arrangement, the inner surface of the ring body 111 is smooth, in close contact with the pot body 104, and has a good heat transfer effect.

[0065] Alternatively, the inner and outer surfaces of the ring body 111 may be formed with concave-convex patterns 113, and a shielding layer 216 may be provided on the outer surface of the ring body 111. Such a configuration may, for example, provide a larger thermal fluid capacity and improve the heat transfer effect.

[0066] The shielding layer 216 is a heat conductive material shielding layer 216 to enhance heat transfer. For example, the shielding layer 216 may be an aluminum layer.
