[0046] As shown in Figures 1 to 9 The present application provides a food heater, which comprises a shell 10, a heating cavity 11 and a heat insulation assembly arranged between the heating cavity 11 and the shell 10, the upper end of the heating cavity 11 is arched, the heating cavity 11 comprises left and right oppositely arranged side walls, the heat insulation assembly comprises a heat insulation piece 12 and a support piece 13 arranged between the side wall of the heating cavity 11 and the heat insulation piece 12, the side of the support piece 13 facing the side wall is provided with an arc-shaped fitting part 131, the side of the support piece 13 facing the heat insulation piece 12 is provided with a vertical support part 132, the arc-shaped fitting part 131 is fitted on the arc-shaped area 111 of the upper end of the side wall, and the vertical support part 132 is fitted with the heat insulation piece 12 and supports the heat insulation piece 12, so that the heat insulation piece 12 extends to the upper side of the heating cavity 11 along the length direction of the side wall.

[0047] The food heater of the present application is provided with the support piece 13 between the heating cavity 11 and the heat insulation piece 12 for the special-shaped heating cavity 11, the support piece 13 is provided with the arc-shaped fitting part 131 matched with the side wall of the heating cavity 11 and the vertical support part 132 matched with the heat insulation piece 12, the arc-shaped fitting part 131 is fitted on the arc-shaped area 111 of the upper end of the side wall, and the vertical support part 132 is fitted with the heat insulation piece 12 and supports the heat insulation piece 12, so that the heat insulation piece 12 can be indirectly fitted on the arc-shaped area 111 of the side wall through the support piece 13, and the lower end of the heat insulation piece 12 can be directly fitted on the plane area 112 of the side wall, thereby ensuring the close fitting of the heat insulation piece 12 and the heating cavity 11, and improving the heat insulation effect. The vertical support part 132 also supports the upper end of the heat insulation piece 12, so that the upper end of the heat insulation piece 12 can extend to the upper side of the heating cavity 11, surround the space above the heating cavity 11, and further improve the heat insulation effect.

[0048] As shown in Figure 1As shown, the upper end of the heating cavity 11 is arched, and the lower end is square. The side walls of the left and right sides of the heating cavity 11 each include an arc-shaped area 111 at the upper end and a planar area 112 at the lower end. If the heat insulation member 12 is directly attached to the side wall, a poor attachment condition is likely to occur at the position where the arc-shaped area 111 and the planar area 112 transition, resulting in a decrease in the heat insulation effect. By using the support member 13, the arc-shaped area 111 and the planar area 112 are attached in different ways. The arc-shaped attachment portion 131 is attached to the arc-shaped area 111, and the vertical support portion 132 is attached to the heat insulation member 12. The arc-shaped attachment portion 131 and the vertical support portion 132 are integrally provided. The attachment effect of the heat insulation member 12 and the arc-shaped area 111 is improved by using a similar shape to achieve a closer fit. At the same time, the lower end of the heat insulation member 12 can be directly attached to the planar area 112. In this way, the attachment effect of the heat insulation member 12 and the heating cavity 11 as a whole is ensured, and a poor local attachment condition is prevented, thereby ensuring the heat insulation effect.

[0049] The heat insulation member 12 extends along the circumference of the side wall. Preferably, the heat insulation member 12 is arranged around the heating cavity 11. Alternatively, as shown in FIG. 2, the heat insulation member 12 is arranged in a U-shaped manner around the heating cavity 11. Figure 2 and Figure 3 As shown, the heat insulation member 12 is arranged in a U-shaped manner around the heating cavity 11. Based on the use of the support member 13, the top and side portions of the U-shaped heat insulation member 12 can each have a planar structure, which is simple in structure. The material of the heat insulation member 12 can be aerogel felt, which has a low thermal conductivity and good heat insulation effect.

[0050] The support member 13 of the present application can be made of a flexible or rigid heat insulation material. It can satisfy the requirements of closely attaching the arc-shaped attachment portion 131 to the arc-shaped area 111 at the upper end of the side wall, attaching and supporting the vertical support portion 132 to the heat insulation member 12, and constituting an intermediate heat insulation layer by itself. The support member 13 can further prevent the heat of the heating cavity 11 from being transmitted outward, which is conducive to reducing the temperature of the outer shell 10 and preventing deformation or scalding of the user.

[0051] In the first embodiment, the support member 13 is a flexible member. When in use, the support member 13 is bent to form the arc-shaped attachment portion 131 and the vertical support portion 132.

[0052] It can be understood that the flexible support member 13 can be deformed flexibly according to the actual shape of the heating cavity 11 to bend and form the arc-shaped attachment portion 131 that closely fits the arc-shaped area 111 and the vertical support portion 132 that closely fits the heat insulation member 12, thereby improving the attachment effect and enhancing the heat insulation effect. In addition, the flexible support member 13 does not require a specific shape during the processing stage, has low processing difficulty, is easy to manufacture, and has low cost. Furthermore, the flexible support member 13 has a flexible shape when it is shipped as a spare part. Since it is not worried about deformation during transportation, the packaging requirement is low, and the packaging cost can be reduced.

[0053] Preferably, the support 13 can be selected from aerogel felt, which has low thermal conductivity and good heat insulation effect.

[0054] In one embodiment, as shown in Figure 4 and Figure 5 , the bottom end of the vertical support part 132 abuts against the arc-shaped fitting part 131. By making the bottom end of the vertical support part 132 abut against the arc-shaped fitting part 131, the stability of the shape of the support 13 can be reinforced, and the existence of a gap 136 between the vertical support part 132 and the arc-shaped fitting part 131 after bending can be prevented, so that the support 13 is not easily deformed and the fitting effect of the support 13 with the heat insulation part 12 and the heating cavity 11 is affected.

[0055] In a second embodiment, as shown in Figure 6 , the support 13 is a rigid member, and the support 13 comprises a horizontal connecting plate 133 and arc-shaped plates 134 and vertical plates 135 respectively arranged at both ends of the connecting plate 133, the arc-shaped plates 134 form arc-shaped fitting parts 131 on the side away from the connecting plate 133, and the vertical plates 135 form vertical support parts 132 on the side away from the connecting plate 133.

[0056] It can be understood that, by using the rigid support 13 to directly form a specific shape, the fitting effect with the heat insulation part 12 and the heating cavity 11 is met, and in the installation stage, the support 13 can be directly used without bending, so that the installation steps can be simplified and the efficiency can be improved.

In use, the support 13 can be directly used without manual bending, the assembly is more convenient, and the support 13 can be manufactured using a forming mold, so that the product consistency is good.

[0058] In one embodiment, as shown in Figure 6 and Figure 7 , a gap 136 is provided between the bottom end of the arc-shaped plate 134 and the vertical plate 135. By forming the gap 136, an air heat insulation layer is formed between the arc-shaped plate 134 and the vertical plate 135, which is conducive to reducing the heat transfer from the arc-shaped plate 134 to the vertical plate 135 and then to the outside, thereby improving the heat insulation effect; in addition, under the premise of ensuring the supporting effect, the arc-shaped plate 134 does not need to be processed too long, so that the material can be reduced and the cost can be saved.

[0061] As a preferred embodiment, the heat insulation assembly further comprises a front heat insulation layer 20 arranged at the front end of the heat insulation piece 12, and the front heat insulation layer 20 is located above the front side opening of the heating cavity 11.

[0062] As shown in Figure 2 , by arranging the front heat insulation layer 20, the front heat insulation layer 20 and the upper end of the heat insulation piece 12 enclose a heat insulation cavity, the heat insulation effect of the upper end of the heating cavity 11 can be optimized, the path of heat transmission to the top of the outer shell 10 is prolonged, and the top of the outer shell 10 is prevented from being overheated and easily scalding the user. As shown in Figure 5 or Figure 7 , the upper end of the heat insulation piece 12 is higher than the heating cavity 11, so as to facilitate accommodating the support 13, the catalytic module 21 and other structures between the heat insulation piece 12 and the heating cavity 11, the space utilization can be improved under the premise of ensuring the heat insulation effect, the compactness between structures is promoted, and the front heat insulation layer 20 is used for plugging the front end of the heat insulation piece 12, and the heat insulation effect is further ensured.

[0065] The pressing ribs 22 can further ensure that the heat insulation member 12 is tightly attached to the heating cavity 11, and can prevent poor attachment caused by unstable installation of the heat insulation member 12, thereby ensuring the heat insulation effect and providing a guarantee for continuous and stable attachment of the heat insulation member 12 to the heating cavity 11.

[0066] It can be understood that the front heat insulation layer 20, the main heat insulation layer and the rear heat insulation layer can be first bonded and fixed during installation, and then pressed by the shell 10, which provides double protection and improves the stability of the heat insulation assembly.

[0067] Further, as shown in Figure 9 The pressing ribs 22 are provided with a plurality of ribs extending along the length direction of the heating cavity 11, and the inner wall of the shell 10 is further provided with a plurality of reinforcing ribs 23, the reinforcing ribs 23 are staggered with the pressing ribs 22, and the protruding height of the reinforcing ribs 23 is less than that of the pressing ribs 22.
