[0067] Exemplary embodiments according to the present application will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in various different forms, and should not be construed as being limited to only the embodiments set forth herein. It should be understood that the embodiments are provided so that the present application will be thorough and complete, and to fully convey the concept of the exemplary embodiments to those of ordinary skill in the art.

[0068] The present application provides a cooking appliance, which includes a pot body and a cover. The pot body has a cylindrical-shaped inner pot receiving portion. An inner pot is fixedly arranged at the inner pot receiving portion, or can be freely put into or taken out of the inner pot receiving portion, to facilitate cleaning of the inner pot. The inner pot is usually made of a metal material and has a circular opening on the upper surface, for containing materials to be heated, such as rice, soup, etc. The pot body includes a heating device for heating the inner pot, to heat the inner pot.

[0069] It can be understood that the cooking appliance according to the present application can be an electric rice cooker, an electric pressure cooker or other cooking appliances, and the cooking appliance can have various functions in addition to the function of cooking rice, such as cooking porridge, etc.

[0070] The cover body has a shape substantially corresponding to that of the pot body. The cover body is arranged on the pot body in an openable and closable manner, specifically, it is pivotally connected to the pot body through a pivot shaft and can be freely pivoted about a pivot axis defined by the pivot shaft between a closed position and an open position relative to the pot body to facilitate closing and opening of the pot body. When the cover body is closed on the pot body, it covers the inner pot and forms a cooking space between the cover body and the inner pot. The cover body also usually has a pot opening sealing ring made of, for example, rubber material arranged between the cover body and the inner pot for sealing the cooking space when the cover body is in the closed state.

[0071] It should be noted that the directional terms used herein in the description of various components, parts, etc. of the pot body, such as "upper", "lower", "upper side", "lower side", "upward", "downward", "upwardly", "downwardly", etc. are relative to the pot body in a horizontal placement and upright state. If not otherwise specified, "inward" in the directional terms "inward", "outward", "inwardly", "outwardly", "inner side", "outer side", etc. means close to the center of the pot body, and "outward" means away from the center of the pot body.

[0072] As shown in Figures 1 to 5 The inner pot includes an inner pot body 100. In order to make the food material in the inner pot evenly heated, the material of the inner pot body 100 is generally selected from a material with high thermal conductivity, which makes the heat easily and quickly transferred to the external environment, resulting in a decrease in cooking efficiency, an increase in energy consumption, and an impact on the taste and quality of the food.

[0073] In the present solution, the inner pot further includes a heat preservation cover 200. The heat preservation cover 200 is sleeved to the outer wall of the inner pot body 100, and a gap 300 is formed between the heat preservation cover 200 and the inner pot body 100. The gap 300 is filled with an adhesive 310, and the heat preservation cover 200 is attached to the outer wall of the inner pot body 100 through the adhesive 310. Through the arrangement of the adhesive 310, it is ensured that the heat preservation cover 200 is not easy to fall off, and thus the stability and durability of the entire inner pot structure can be improved. Generally, the thermal expansion and contraction coefficient of the inner pot body 100 is greater than that of the heat preservation cover 200, and the inner pot body 100 will expand and become larger after being heated. The cured adhesive 310 has good shrinkage elasticity and can absorb or relieve external stress or deformation within a certain range, so it can buffer or absorb the deformation of the inner pot body 100, and reduce the stress on the connecting part between the inner pot body 100 and the heat preservation cover 200 caused by the deformation of the inner pot body 100. When the inner pot body 100 expands due to the thermal expansion and contraction effect during heating, the adhesive 310 can effectively absorb and disperse the stress generated thereby, preventing it from directly acting on the heat preservation cover 200, thereby avoiding the risk of the heat preservation cover 200 being broken due to excessive stress. When the inner pot body 100 shrinks during cooling, the adhesive 310 can ensure that the heat preservation cover 200 and the inner pot maintain a stable connection state, preventing the heat preservation cover 200 from falling off due to uneven shrinkage.

[0074] In some embodiments of the present application, the inner pot body 100 is made of a magnetic metal material, or the inner pot body 100 is provided with a magnetic metal layer. The inner pot body 100 can be directly heated by electromagnetic heating, and under the action of an electromagnetic field, it can rapidly and uniformly heat up, achieving uniform heating of food materials, thereby improving the cooking effect and food taste.

[0075] Correspondingly, the pot body includes an electromagnetic heating device, such as an electromagnetic coil disc, for heating the inner pot, to heat the inner pot. Optionally, the electromagnetic heating device is located below the inner pot.

[0076] In some embodiments of the present application, the heat preservation cover 200 is made of a ceramic material. The thermal conductivity of ceramic material is low, thereby effectively preventing heat transfer. When the heat preservation cover 200 is made of a ceramic material, heat exchange between the inner pot and the external environment can be significantly reduced, thereby maintaining the stability of the temperature inside the inner pot, achieving heat accumulation and heat preservation, and the heat loss is small. Therefore, the heating time of the cooking appliance will be correspondingly reduced, the overall energy efficiency is improved, the temperature difference in the pot is smaller, thereby improving the cooking efficiency and reducing energy consumption. Ceramic has excellent high-temperature resistance and can maintain its structure and performance stability under high-temperature environment, and will not be affected by high temperature. In the present application, although the heat preservation cover 200 itself does not directly participate in the electromagnetic heating process, it reduces heat loss, so that more energy of electromagnetic heating is used to heat the food materials in the inner pot, thereby improving the overall energy efficiency.

[0077] In some embodiments of the present application, the adhesive 310 is a high-temperature adhesive. The high-temperature adhesive can ensure the firm adhesion between the inner pot body 100 and the heat preservation cover 200, and can maintain sufficient adhesion strength even under high-temperature environment.

[0078] In the present application, the inner pot body 100 is configured as a rotary body structure. Optionally, the inner pot body 100 includes at least one of an arc-shaped portion 110, an inclined wall portion, and a straight wall portion 120.

[0079] Optionally, the arc-shaped portion 110 is gradually widened from bottom to top along the height direction DH of the inner pot. Optionally, the arc-shaped portion 110 can form the bottom and at least part of the sidewall of the inner pot body 100, or the arc-shaped portion 110 can form the bottom of the inner pot body 100, or the arc-shaped portion 110 can form the sidewall of the inner pot body 100. When the arc-shaped portion 110 can form the bottom and at least part of the sidewall of the inner pot body 100, or the arc-shaped portion 110 can form the bottom of the inner pot body 100, the diameter or width of the arc-shaped portion 110 of the inner pot body 100 gradually increases with the increase of the height from the bottom. The arrangement of the arc-shaped portion 110 helps to optimize the uniformity of electromagnetic heating of the inner pot body 100. Optionally, the electromagnetic heating device of the pot body is arranged at the bottom, and the arrangement of the arc-shaped portion 110 can ensure that the heat is gradually dispersed during the upward transmission, reducing the situation that the bottom is overheated and the top is insufficiently heated. When the arc-shaped portion 110 can form the sidewall of the inner pot body 100, the diameter or width of the arc-shaped portion 110 of the inner pot body 100 gradually increases with the increase of the height.

[0080] Optionally, the inclined wall portion is gradually widened from bottom to top along the height direction DH of the inner pot. Optionally, the inclined wall portion can form at least part of the sidewall of the inner pot body 100. Specifically, the sidewall of the inner pot gradually increases in diameter or width with the increase of the height from the bottom.

[0081] Optionally, the straight wall portion 120 is a straight wall extending along the height direction DH of the inner pot. Optionally, the straight wall portion 120 can form at least part of the sidewall of the inner pot body 100, thereby forming a vertical side surface.

[0082] The arrangement of the above-mentioned inner pot body 100 facilitates the installation and disassembly of the heat preservation cover 200 through the gradually widened or vertically extended structure. After being processed into a shape suitable for the inner pot body 100, the heat preservation cover 200 can be directly sleeved on the outer wall of the inner pot body 100, and the heat preservation cover 200 can effectively wrap the inner pot body 100, thereby ensuring good heat preservation effect.

[0083] Referring to Figure 3 In some embodiments of the present application, the heat preservation cover 200 includes a bottom portion 210 and a sidewall portion 220 extending upward from the bottom portion 210.

[0084] Referring to Figure 4 In some embodiments of the present application, the inner pot body 100 includes an arc-shaped portion 110 and a straight wall portion 120 extending upward from the arc-shaped portion 110. The heat preservation cover 200 is arranged in a shape suitable for the inner pot body 100. Specifically, the bottom portion 210 of the heat preservation cover 200 is gradually widened from bottom to top, and the sidewall portion 220 of the heat preservation cover 200 forms a vertical side surface.

[0085] Back to Figure 3As known from the foregoing, the main function of the heat preservation cover 200 is heat accumulation and preservation. A temperature measuring element (such as a temperature sensor) usually needs to directly contact a heat source to be measured so as to accurately obtain temperature information. In the case where the heat preservation cover 200 covers the inner body 100, due to the heat insulation effect of the heat preservation cover 200, the temperature measuring element can not directly and accurately perceive the actual temperature of the inner body 100. The heat preservation cover 200 is provided with an opening 201 at the bottom 210 or the side 220, so that part of the inner body 100 is exposed from the opening 201. Through the provision of the opening 201, the temperature measuring element is allowed to directly contact the inner body 100, so that the temperature can be more accurately measured.

[0086] Optionally, as shown in Figure 3 , the opening 201 is located at the center of the bottom 210. The center of the inner body bottom is the main area of most cooking utensils to be heated. The provision of the opening 201 at this position is conducive to the accuracy of temperature measurement, so as to accurately control the heating process and ensure the cooking quality and taste of food. In addition, the opening 201 also facilitates the positioning of the inner body during installation into the pot body.

[0087] In this scheme, the temperature measuring element is arranged opposite to the opening 201, and the temperature measuring element can extend into the opening 201 to contact the inner body 100.

[0088] Optionally, the diameter of the opening 201 is 2-100mm. If the opening 201 is too large, the heat preservation effect can be reduced, and if the opening 201 is too small, the accurate installation and use of the temperature measuring element can be affected. The provision of the opening 201 with the size balances the heat preservation effect and the convenience of temperature measurement.

[0089] In some embodiments of the present application, as shown in Figure 2 , the thickness of the heat preservation cover 200 is T, wherein 3mm≤T≤9mm. The heat preservation cover 200 with the thickness can control the cost and weight while ensuring the heat preservation effect.
