The detachable cover 110 includes a cover plate 111 and a mounting bracket 113, wherein the cover plate 111 is usually made of metal material, and the mounting bracket 113 is usually made of plastic material.
[0060] The mounting bracket 113 is detachably arranged on the inner liner 102, the cover plate 111 is connected to the mounting bracket 113, and there is a gap between the cover plate 111 and the inner liner 102. The heating assembly 130 is arranged in the gap. The sealing device 120 is connected to the inner liner 102 and the detachable cover 110 to seal the gap and form a sealed cavity 115, wherein the cover plate 111 is located in the sealed cavity 115.
[0061] According to the cover 100 of the present application, the gap between the cover plate 111 of the detachable cover 110 and the inner liner 102 is sealed to be isolated from the external atmosphere, so that the heating assembly 130 is less affected by the external environment when working, and the cover plate 111 is less likely to have temperature difference, reducing the possibility of condensate water generation and improving the heat preservation effect on the upper part of the food.
[0062] Specifically, referring to Figure 1 and Figure 2 , the heating assembly 130 includes a heat preservation plate 131 and a heating element 132. The heat preservation plate 131 is connected with the inner liner 102, and the heating element 132 is arranged between the heat preservation plate 131 and the inner liner 102. The heating element 132 can be an infrared emitter, which can be arranged on the back of the heat preservation plate 131.
[0063] As a preferred embodiment, the sealing device 120 is arranged separately from the heating assembly 130. More specifically, the sealing device 120 is arranged separately from the heat preservation plate 131 of the heating assembly 130, so as to separate the sealing device 120 with low thermal conductivity from the heat preservation plate 131, leaving some space to increase the area of the heat preservation plate 131 in contact with air, improve the heat transfer from the heating assembly 120 to the sealed cavity 115, and enable sufficient thermal convection of the heat generated by the heating element 132 in the sealed cavity 115, thereby improving the heat transfer speed between the heating assembly 130 and the cover plate 111 of the detachable cover 110. Moreover, such arrangement can also enclose the heating assembly 130 on the inside, improving the heat preservation effect.
[0064] Referring to Figure 2 , Figure 4 and Figure 5 , the sealing device 120 includes a first sealing portion 121 and a second sealing portion 124. The first sealing portion 121 is connected with the inner liner 102, and the second sealing portion 124 is at least partially located between the cover plate 111 and the mounting groove 114, and is further used to connect with the inner pot 21 of the cooking utensil 10. Thus, the sealing of the gap between the inner liner 102 and the cover plate 111 can be achieved, and the sealing of the inner pot 21 when the cover is closed can also be achieved.
[0065] More specifically, the mounting groove 114 is provided on the mounting frame 113, and the edge of the cover plate 111 has a bending structure 112. The mounting groove 114 is shaped to cooperate with the bending structure 112 of the cover plate 111, so as to achieve stable mounting of the cover plate 111. Correspondingly, the second sealing portion 124 of the sealing device 120 has a bending portion 125 shaped to cooperate with the mounting groove 114 and the bending structure 112, so that the bending portion 125 is connected between the mounting groove 114 and the bending structure 112, thereby forming stable mounting of the sealing device 120. In addition, the second sealing portion 124 further has a pot opening sealing portion 126, which is used to connect with the inner pot 21.
[0066] In this embodiment, the sealing device 120 is continuously arranged around the edge of the cover plate 111 to completely seal the edge of the cover plate 111, further reducing the possibility of regional temperature differences on the cover plate 111. As an example, the first sealing part 121 and the second sealing part 124 are connected and constructed as an integral component, so that the sealing device 120 surrounds the cover plate 111. In this way, a single sealing component is used to seal the gap between the removable cover 110 and the inner liner 102, the gap between the cover plate 111 and the mounting bracket 113, and the gap between the removable cover 110 and the inner pot 21, saving material costs and improving assembly efficiency.
[0067] In this embodiment, the sealing device 120 is actually part of the removable cover 110. By integrating the first sealing part 121 into the original sealing element of the removable cover 110, material costs are saved and no assembly process is added.
[0068] Second Implementation Method
[0069] The second preferred embodiment of this utility model is a variation of the first preferred embodiment. Except for the sealing device 120, the cover 200 of the second preferred embodiment has a structure and / or construction similar to the cover 100 of the first preferred embodiment. Therefore, elements having substantially the same function as those in the first preferred embodiment will be given the same designations herein, and for the sake of brevity, will not be described in detail and / or illustrated further.
[0070] Figure 6 , Figure 7 , Figure 8 and Figure 9 A second embodiment of this application is shown. In this embodiment, the sealing device 220 has a first sealing portion 221 and a second sealing portion 124 similar to those in the first embodiment, except that the first sealing portion 221 and the second sealing portion 124 are constructed as independent components, with the first sealing portion 221 connected between the inner liner 102 and the mounting bracket 113. Therefore, a sealing function for the gap between the removable cover 110 and the inner liner 102 can be added with minimal changes to the structure of the removable cover 110, resulting in low design and production modification costs.
[0071] In one implementation, the first sealing part 221 includes a functional part 222 and a connecting part 223. The inner liner 102 is provided with a fixing structure 203. The functional part 222 is continuously arranged along the circumference of the inner liner 102 and connected between the inner liner 102 and the mounting bracket 113. The connecting part 223 is connected to the fixing structure 203. This structural form can provide a good seal while also having a strong connection capability.
[0072] As an example, the fixing structure 203 may be a slot formed on the liner 102, and the connecting portion 223 of the first sealing portion 121 may be a buckle set on the functional portion 222.
[0073] In this embodiment, it can be understood that the detachable cover 110 structure is inconvenient, and a sealing structure (first sealing part 221) is designed on the inner liner 102, so that the detachable cover 110 can be combined to achieve a sealing effect on the sealing cavity 115.
