The insulation layer 34 may be made of insulation cotton, thereby being able to meet the insulation requirements of the cooking chamber 30 inside the second box 3 and reduce the influence of the high temperature of the cooking chamber 30 on the temperature in the first refrigeration chamber 20 and the second refrigeration chamber 40.

[0081] Based on the above technical solution, the embodiment of the utility model has at least the following advantages and positive effects:

[0082] In the household appliance of the embodiment of the utility model, a first box 2 and a second box 3 are arranged in a box body 1, a first refrigeration chamber 20 is formed in the first box 2, and a cooking chamber is formed in the second box 3; at the same time, an evaporation chamber 5 is arranged in the box body 1, and the evaporation chamber 5 can transmit cold air to the cooking chamber 30 through the first air supply duct 51, so as to realize refrigeration in the cooking chamber 30, that is, to realize low-temperature storage of the food in the cooking chamber 30; when the food in the cooking chamber 30 needs to be processed, the cooking chamber 30 is heated by the heater 31, so as to realize high-temperature cooking of the food in the cooking chamber 30. At the same time, the heat dissipation fan 61 and the heat dissipation duct 6 are used to extract and discharge the heat in the cooking chamber 30 through the heat dissipation duct 6 when or after the heater 31 is heated to the outside of the box body 1, so as to effectively prevent the heat from being transferred to the evaporation chamber 5 through the first air supply duct 51, so that the household appliance forms a combination product that can realize low-temperature storage and high-temperature cooking respectively, effectively prevent the reduction of the refrigeration efficiency of the refrigeration system, save space and reduce energy consumption.

[0083] Although the utility model has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the utility model can be implemented in a variety of forms without departing from the spirit or essence of the utility model, it should be understood that the above-mentioned embodiments are not limited to any of the aforementioned details, but should be widely interpreted within the spirit and scope defined by the attached claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the attached claims.
