The cold air in the freezing chamber 12 at low temperature can enter the temperature-changing cavity 112 through the air supply duct formed by the temperature-changing air supply pipe 15 to cool the air in the temperature-changing chamber. Since the temperature of the cold air in the freezing chamber 12 is low, the wide temperature changing function can be easily realized in the temperature changing chamber 112 located locally in the refrigerating chamber 11.

The upper end of the temperature-changing air return pipe 16 is communicated with the temperature-changing cavity 112, and the lower end of the temperature-changing air return pipe 16 can be communicated with the freezing chamber 12, so that a return air duct is formed between the freezing chamber 12 and the temperature-changing cavity 112.
