Specifically, the duct groove 21 has an intake opening 211 and a return opening 212, the intake opening 211 being for intake of cold air, and the return opening 212 being for discharge of cold air. Both the intake vent 211 and the return vent 212 are formed at the side of the heat-insulating plate 2. In order to improve the sealing performance of the heat insulation assembly 10, the heat insulation assembly 10 further comprises a heat insulation plate 4, the heat insulation plate 4 is arranged between the heat insulation plate 2 and the cooling plate 3 and located on the side face of the cover plate 1, wherein the heat insulation plate 4 can seal other gaps between the heat insulation plate 2 and the cooling plate 3 except for the air inlet 211 and the air return opening 212, cold air in the air duct groove 21 can not leak into the ice temperature drawer from other gaps between the heat insulation plate 2 and the cooling plate 3, and further the heat insulation plate 4, the heat insulation plate 2 and the cooling plate 3 are arranged in a surrounding mode to form a sealing space, so that the sealing performance of the heat insulation assembly 10 is further improved, and the refrigerating effect of the heat insulation assembly 10 is further improved.
