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.
