[0032] The embodiment of the present application provides an electric rice cooker inner container, as shown in the figure, the electric rice cooker includes a heating disc 300, and the electric rice cooker inner container includes an inner container main body 100 and a first base 200; the first base 200 is connected to the bottom of the inner container main body 100, and a first cavity 210 with a semi-closed structure is arranged in the first base 200, and the heating disc 300 is arranged in the first cavity 210 and connected with the inner container main body 100. Figures 1 to 5

[0033] Specifically, the electric rice cooker inner container includes an inner container main body 100 and a first base 200 arranged at the bottom of the inner container main body 100, the inner container main body 100 is used to carry the heated material, and the inner container main body 100 is used to conduct the heat generated by the heating disc 300 to the heated material; the first base 200 is used to facilitate the user to hold the inner container main body 100 as a tableware bowl, and the first base 200 is also used to place the heating disc 300 to prevent the heat generated at the heating disc 300 from being convected with the air around the heating disc 300, further preventing the heat at the bottom of the inner container main body 100 from being lost too much, thereby improving the heating efficiency of the heating disc 300 to the inner container main body 100, shortening the cooking time, and further improving the convenience of the user eating. It should be noted that the first base 200 is provided with a cavity, and the bottom of the first base 200 is provided with an opening communicating with the cavity, so that the first base 200 has a first cavity 210 with a semi-closed structure.

[0034] ​In actual use, the substance to be heated is placed in the inner container body 100, and then the heating disc 300 is placed in the first chamber 210. When the heating disc 300 is located in the first chamber 210, the heating disc 300 is in contact with the bottom of the inner container body 100 and heats the inner container body 100. During heating, the first chamber 210 arranged inside the first base 200 reduces the convection of air around the heating disc 300 to reduce the loss of heat around the heating disc 300; after cooking is completed, the inner container body 100 is separated from the heating disc 300, and the user can directly use the inner container body 100 as a tableware bowl. The first base 200 facilitates the user to take during dining. The embodiment of the present application provides an inner container of an electric rice cooker, which solves the problem of low convenience of the user in eating by arranging the first base 200 at the bottom of the inner container body 100.

[0035] In specific embodiments, as shown in Figure 1 and Figure 2 , the first base 200 is a flared mouth structure, and the smaller-diameter end of the flared mouth structure is connected to the inner container body 100.

[0036] Specifically, the first base 200 is arranged in a flared mouth structure to facilitate the separation of the heating disc 300 from the first chamber 210 after cooking is completed. As shown in Figure 1 The embodiment of the present application provides an inner container of an electric rice cooker and a heating disc assembly structure, and Figure 2 The embodiment of the present application provides an inner container of an electric rice cooker and a heating disc assembly structure, and

[0037] It should be noted that the flared mouth structure can be provided with a plurality of air holes to ensure the uniformity of the heating of the inner container body 100. In addition, the smaller-diameter end of the flared mouth structure can be connected to the side of the inner container body 100.

[0038] In specific embodiments, as shown in Figure 3 and Figure 4 , the electric rice cooker inner container further comprises a second base 110, and the second base 110 is detachably connected to the inner container body 100. The second base 110 is provided with a second chamber 111 in a semi-enclosed structure, and the second chamber 111 is used to place the inner container body 100.

[0039] Specifically, the second base 110 is used to prevent the inner container body 100 from scalding the user due to excessive temperature, and plays a role of heat insulation. After cooking is completed, the inner container body 100 is placed in the second cavity 111, and the user can directly use the inner container body 100 as a tableware bowl, thereby saving the waiting time of the user for dining and improving the convenience of eating. It should be noted that the height of the second base 110 is less than the height of the inner container body 100, and preferably, the height of the second base 110 and the height of the inner container body 100 satisfy h1:h2 = 1 / (2-4), and preferably h1:h2 = 1 / 3, wherein h1 represents the height of the second base 110, and h2 represents the height of the inner container body 100.

[0040] As shown in Figure 3 The second base 110 of the inner container of the electric rice cooker provided by the embodiment of the present application is shown in the overall structure diagram, and the second cavity 111 is arranged in the second base 110. The shape of the second cavity 111 is matched with the shape of the bottom of the inner container body 100. It should be noted that the second base 110 can also be other structures without affecting the use performance of the second base 110.

[0041] In the specific embodiment, as shown in Figure 4 and Figure 5 The bottom of the second base 110 is provided with an annular groove 112, and the groove 112 is in communication with the second cavity 111.

[0042] Specifically, the annular groove 112 is used to place the first base 200 to improve the fitting degree of the second base 110 and the first base 200, and the annular groove 112 is also used to place the cooling liquid to improve the heat insulation effect of the second base 110, and further improve the convenience of the user for eating. As shown in Figure 4 The assembly structure diagram of the inner container body, the first base and the second base of the inner container of the electric rice cooker provided by the embodiment of the present application is shown in Figure 5 that is Figure 4 As shown in the structure enlarged view at A, the second base 110 is sleeved on the bottom of the inner container body 100, and the first base 200 arranged at the bottom of the inner container body 100 is arranged in the groove 112. The groove 112 is used to place the first base 200 and the cooling liquid.

[0043] In the use process, after cooking is completed, a certain amount of cooling liquid is first injected into the groove 112, and then the inner container body 100 and the first base 200 connected with the inner container body 100 are placed in the second base 110. After the inner container body 100 and the first base 200 are placed stably, the user can directly use the inner container body 100 as a tableware bowl, thereby improving the convenience of the user for dining.

[0044] In the specific embodiment, as shown in Figures 3 to 5As shown, the second base 110 is provided with anti-scalding protrusions 113, which are uniformly or non-uniformly distributed on the inner wall of the second cavity 111.

[0045] Specifically, the anti-scalding protrusions 113 are in contact with the outer wall of the inner container body 100, and the heat insulation performance of the second base 110 can be further improved due to the small contact area. In addition, when the second base 110 is provided with cooling liquid, the outer wall of the inner container body 100 and the inner wall of the second base 110 are easily adsorbed due to vacuum negative pressure or water tension, which makes it difficult for the user to separate the second base 110 from the inner container body 100. The anti-scalding protrusions 113 are used to prevent the outer wall of the inner container body 100 and the inner wall of the second base 110 from being adsorbed, thereby improving the convenience of the user. As shown in the enlarged view of the structure at A, when the bottom of the inner container body 100 and the first base 200 are placed in the second base 110, one side of the anti-scalding protrusion 113 is connected to the inner wall of the second base 110, and the other side of the anti-scalding protrusion 113 is in abutment with the inner container body 100. The anti-scalding protrusions 113 form gaps between the inner container body 100 and the inner wall of the second base 110, thereby improving the anti-scalding performance of the second base 110 and further saving the waiting time of the user during meals. Figure 3 The overall structure diagram of the second base of the inner container of the electric rice cooker provided by the embodiment of the present application, Figure 4 The assembly structure diagram of the inner container body, the first base and the second base of the inner container of the electric rice cooker provided by the embodiment of the present application, and Figure 5 That is Figure 4 As shown in the enlarged view of the structure at A, when the bottom of the inner container body 100 and the first base 200 are placed in the second base 110, one side of the anti-scalding protrusion 113 is connected to the inner wall of the second base 110, and the other side of the anti-scalding protrusion 113 is in abutment with the inner container body 100. The anti-scalding protrusions 113 form gaps between the inner container body 100 and the inner wall of the second base 110, thereby improving the anti-scalding performance of the second base 110 and further saving the waiting time of the user during meals.

[0046] In specific embodiments, the anti-scalding protrusions 113 are in a cylindrical structure, the height of the cylindrical structure is 0.5mm to 1.0mm, and the diameter of the cylindrical structure is 2mm to 5mm.

[0047] Specifically, in actual use, when the height of the anti-scalding protrusions 113 is 0.5mm to 1.0mm, especially 0.5mm, 0.6mm, 0.7mm and 1.0mm, the heat insulation effect is good and the assembly is easy; when the diameter of the cylindrical structure is 3mm, 4mm, 4.5mm and 5mm, the heat insulation performance is good. It should be noted that, without affecting the use performance of the anti-scalding protrusions 113, the anti-scalding protrusions 113 can be other structures. The anti-scalding protrusions 113 can be detachable, or can be integrally formed with the cylindrical second base 110.

[0048] In specific embodiments, as shown in Figure 3 As shown, the side wall of the second base 110 is provided with a cooling channel 114, which is in communication with the groove 112.

[0049] Specifically, as shown in Figure 3The second base of the inner container of the electric rice cooker provided by the embodiment of the present application is shown in the overall structural schematic diagram of the second base. The cooling channel 114 is used for guiding the cooling liquid when the cooling liquid is injected into the second base 110, and the cooling channel 114 guides the cooling liquid into the groove 112. In addition, the cooling channel 114 is also used for being adsorbed between the outer wall of the inner container body 100 and the inner wall of the second base 110, so as to facilitate the user to separate the second base 110 from the inner container body 100, thereby improving the convenience of the user.

[0050] In use, the cooling liquid is injected into the groove 112 through the cooling channel 114, and then the inner container body 100 and the first base 200 are placed in the second base 110. When the first base 200 is placed in the groove 112, the cooling liquid cools the first base 200, and at the same time, the first base 200 discharges part of the cooling liquid from the groove 112 to the second chamber 111, and then cools the side wall of the inner container body 100.

[0051] The cooling channel 114 is arranged along the height direction of the second base 110, and a plurality of cooling channels 114 are arranged along the circumferential direction of the second base 110. In use, a small amount of cooling liquid is first injected into the groove 112 through the cooling channel 114, and then the cooling liquid is injected into the plurality of cooling channels 114 to improve the cooling efficiency and further reduce the waiting time of the user during dining.

[0052] In a specific embodiment, the second base 110 is made of rubber material.

[0053] Specifically, the second base 110 is made of high-temperature-resistant food-grade silicone rubber. The high-temperature-resistant rubber has strong plasticity and is convenient to install. In addition, the second base 110 is used as a dough belt. The food-grade silicone rubber is obtained by polycondensation of silicate inorganic polymer gel material, and the content of silicon dioxide is more than 98%. It is non-toxic and odorless, and has stable chemical properties. The food-grade silicone rubber does not react with any acid, alkali or salt except in the environment of hydrofluoric acid. Because it is a colloidal structure, it has a large number of micropores and a large specific surface area. It should be noted that the second base 110 can also be made of other heat insulation materials, for example, the second base 110 can also be made of wood. The wood-made second base 110 has good heat insulation performance, and a handle can be arranged on the outer side wall of the wood-made second base 110, thereby facilitating the user to use.

[0054] Further, the thickness of the second base 110 is 2mm to 4mm.

[0055] Specifically, in actual use, when the thickness of the second base 110 is 3mm, 3.5mm, 3.8mm and 4mm, the heat insulation performance and plasticity of the second base 110 are relatively good. It should be noted that the second base 110 can also have other thicknesses without affecting the use performance of the second base 110.
