As shown in fig. 1, according to an embodiment of the present invention, an insulation assembly 1 is provided for a cooking appliance, the cooking appliance includes a housing 2, the housing 2 includes a first housing wall 21, two sides of the first housing wall 21 are respectively provided with a hot air installation cavity 3 and a cooking cavity 4, the hot air installation cavity 3 is communicated with the cooking cavity 4, and the insulation assembly 1 includes: the heat shield 11 is positioned in the hot air installation cavity 3 and is covered on a part of the first shell wall 21, the heat shield 11 comprises a heat shield cavity 111, one end of the heat shield 11 is open, an avoidance port 112 is arranged at the open end of the heat shield 11, and the avoidance port 112 is positioned on the first side of the heat shield cavity 111 along the first direction and is communicated with the heat shield cavity 111; and the heat insulation cotton 12, wherein one part of the heat insulation cotton 12 is arranged in the heat insulation cavity 111, and the other part extends out of the heat insulation cavity 111 from the avoidance port 112 and covers the other part of the first shell wall 21.

The heat insulation assembly 1 is used for a cooking appliance, the cooking appliance comprises a shell 2, the shell 2 comprises a first shell wall 21, two sides of the first shell wall 21 are respectively provided with a hot air installation cavity 3 and a cooking cavity 4 which are communicated with each other, and further a hot air part 5 in the hot air installation cavity 3 can convey hot air into the cooking cavity 4, so that cooking of food materials in the cooking cavity 4 is realized. The heat insulation assembly 1 comprises a heat insulation cover 11 and heat insulation cotton 12, the heat insulation cover 11 comprises a heat insulation cavity 111, the heat insulation cover 11 is arranged on a part of the first shell wall 21, heat insulation of the first shell wall 21 is achieved, and heat is prevented from being transmitted to an area outside the cooking cavity 4 through the first shell wall 21. Meanwhile, one end of the heat shield 11 is opened, one open end of the heat shield 11 is provided with an avoidance port 112, the avoidance port 112 is located on the first side of the heat shield cavity 111 along the first direction and is communicated with the heat shield cavity 111, one part of the heat shield cotton 12 is arranged in the heat shield cavity 111, the heat shield effect of the heat shield cavity 111 is improved, the other part of the heat shield cotton 12 extends out of the heat shield cavity 111 from the avoidance port 112 and covers the area of the first shell wall 21, which cannot be covered by the heat shield 11, so that the first shell wall 21 is covered by the heat shield structure, heat is prevented from being transferred to the outside of the cooking cavity 4 through the first shell wall 21, and the heat shield effect is improved.

It will be appreciated that the hot air part 5 can be installed in the hot air installation cavity 3, the hot air part 5 is used for carrying hot air to the cooking cavity 4, and the heat of the hot air part 5 can be transferred to the first shell wall 21, so that the heat conduction from the first shell wall 21 to the outside can be avoided by covering another part of the first shell wall 21 with the heat insulation cotton 12.

Optionally, a heat shield 11 is provided outside the hot air section 5.

Alternatively, the first housing wall 21 is a top wall of the housing 2.

It will be appreciated that the projected area of the heat shield 11 is smaller than the projected area of the first housing wall 21, and therefore, the heat shield 11 can only cover a part of the first housing wall 21, so that the heat shield 11 has a relatively poor heat-shielding effect in the area other than the heat shield 11, and heat for cooking the food is easily lost. That is, the present invention can extend the heat insulation cotton 12 out of the heat insulation chamber 111 by providing the escape opening 112, thereby increasing the coverage area of the heat insulation assembly 1.

In the cooking appliance having the inclined side wall, a larger gap is likely to occur between the heat shield 11 and the side wall, and thus, the heat insulating area can be increased and the cooking efficiency can be improved by the heat insulating cotton 12 extending out of the heat insulating chamber 111.

As shown in fig. 1, optionally, heat shield 11 comprises: a top plate 113; a side plate 114, wherein the side plate 114 is arranged around the top plate 113 and surrounds the heat insulation cavity 111 with the top plate 113, and one end of the heat insulation cover 11 opposite to the top plate 113 is opened; the outer edge 115, the outer edge 115 encloses and locates the one end that the curb plate 114 kept away from roof 113, along the first direction, and the outer edge 115 of the first side of thermal-insulated chamber 111 is equipped with first heavy platform 116, and first heavy platform 116 is sunken to roof 113 direction and encloses and closes out and dodges the mouth 112.

In this embodiment, specifically, the heat shield 11 includes a top plate 113, a side plate 114 and an outer edge 115, where the top plate 113 and the side plate 114 can enclose a heat insulation cavity 111, that is, the side opposite to the top plate 113 is in an open structure, a first sinking table 116 is disposed on the outer edge 115 of the first side of the heat insulation cavity 111, that is, the outer edge 115 of the first side is concave toward the top plate 113, and by disposing the first sinking table 116, an avoidance opening 112 is formed, so that the heat insulation cotton 12 can extend out of the heat insulation cavity 111 through the avoidance opening 112, and the heat insulation coverage area is increased.

Optionally, after installation of the insulation assembly 1 is completed, the top plate 113 is positioned over the entire insulation shield 11 and the side plates 114 are bent downwardly to define the insulation cavity 111. The outer edge 115 is disposed around an end of the side plate 114 away from the top plate 113, that is, the downwardly bent side wall is bent in a horizontal direction instead at the end away from the top plate 113, so as to form the outer edge 115.
