Refrigerator with wet air layer heat insulation construction

The utility model relates to a refrigerator with wet air layer heat insulation construction which belongs to the technical field of the refrigeration and energy saving to solve the technical problem of the refrigerator which is composed of thermal insulating materials filled between an outer wall and an inner wall. When the thermal insulating material maintains dry, a thermal insulation layer is provided with favorable heat-insulating property. The utility model is characterized in that the wall of the refrigerator is provided with an air gap layer, the aluminium foil, and a water storage tank. When the inner wall reaches the saturated humidity, both sides of the air gap layer exist the temperature difference, so the relative humidity of the position approaching the outer wall becomes more and more low. If the thermal insulation layer has the remaining moisture, the moisture diffuses to the inner wall by the vapor permeability, and then coagulates into water or separates out frost to ensure the drying of the thermal insulating material. The utility model is suitable for various refrigerators.
