PURPOSE:To sublimate or vaporize efficiently the dew which the air of an ordinary temperature forms on the inner wall surface of a high-humidity chamber by a construction wherein a humidity conditioning plate is provided in the part in the rear of the high-humidity chamber which faces an outlet of cold air coming from a cooler, and wherein the terminal of a cold air passage for making the cold air flow onto the surface of the humidity conditioning plate is made to be in proximity to a cold air return passage of a refrigerating chamber. CONSTITUTION:Cold air cooling down a refrigerating chamber 3 and a vegetable chamber 4 is sucked into a cold air return port 19 and returned to a cooler 9. Then, the air cooled down by the cooler 9 is forced to circulate through a cold air passage 20 formed between a cover 15 and the upper side of a frame 17. A square hole of an inner box 11 provided at the terminal part of the cooling passage 20 is provided at a position being opposite to the cold air return port 19 and the cold air flowing through the cold air passage 20 is returned through it smoothly to the cooler 9. Accordingly, moisture condensed on the surface of a humidity conditioning plate 18 is vaporized or sublimated by this cold air in a large quantity. The humidity in a high- humidity chamber is kept at 70% or above anytime, of course, and the quantity of the moisture condensed on the surface of the humidity conditioning plate 18 is that of overflow. |
