前記仕切板９の前面に設けられた冷気戻り口である。An example of this technique will be described below with reference to FIGS. Reference numeral 1 denotes a refrigerator body, which is composed of an outer box 2, an inner box 3, and a heat insulating material 4 filled between the two boxes 2, 3. Reference numeral 5 denotes a partition wall which forms a freezer compartment 6 at the upper part and a refrigerator compartment 7 at the lower part. Reference numeral 8 denotes a vegetable room provided at the lower part of the refrigerator compartment, which is separated from the refrigerator compartment 7 by a partition plate 9. Reference numeral 10 denotes a door provided to face the vegetable room 8. Numeral 11 denotes a vegetable container which is detachably held by the door 10 and has an open upper surface. The vegetable container 11 is simultaneously pulled out of the refrigerator by pulling out the door 10 so that vegetables can be taken in and out. Reference numeral 12 denotes a lid disposed in close contact with the upper opening of the vegetable container 11, a resin flat plate 13 having a large number of through holes, and a moisture permeable membrane 14 welded to one surface of the flat plate 13. And a packing 15 made of vinyl chloride or the like disposed around the flat plate 13. Here, the moisture permeable film 14 will be described.
The moisture permeable membrane 14 includes a silicon thin film 16 and a hydrophilic nylon fiber.
The silicon thin film 16 has a thickness of about 10 μ to about
Most consist chain molecular aggregates amorphous at a film thickness of about 50.mu., a collection of these chain molecules completely blocked liquid and has a gas permeability by the intermolecular spacing of 10 to 10 3 Å . In other words, water vapor, air, and carbon dioxide are permeated if there is a concentration difference between the inside and outside of the film. The use of the hydrophilic nylon fibers 17 is for preventing dew condensation. Next, reference numeral 18 denotes a cool air inlet for taking in cool air from the refrigerating room 7, which is formed by a gap between a rear end face of the partition plate 9 and the inner box 3. Reference numeral 19 denotes a cool air convection passage which communicates with the cool air intake 18 and convects the cool air to the outer periphery of the vegetable container 11, and reference numeral 20 communicates with the cool air convection passage 19 and is provided on the front surface of the partition plate 9. It is a cold air return.

が飽和湿度以上の水分は蓋体12の透湿膜14を介して容器
外へ徐々に透湿していく。こうして、野菜容器11内は野
菜の保存に適しているといわれるRH80〜95％の湿度に保
たれ野菜保鮮の所期の目的が達せられる。In such a configuration, the cold air taken in from the refrigerator compartment 7 through the cold air inlet 18 does not directly flow into the vegetable container 11, but indirectly flows through the inside of the vegetable container 11 from the outer periphery when convection through the cool air convection passage 19. After the cooling, the air is returned into the refrigerator compartment 7 through the cool air return port 20. In addition, the water inside the vegetable container 11 becomes highly humid due to the water evaporating from the vegetables stored in the vegetable container 11, but water having a saturation humidity or more gradually permeates out of the container through the moisture permeable membrane 14 of the lid 12. I will do it. In this way, the inside of the vegetable container 11 is kept at a humidity of 80 to 95% RH, which is said to be suitable for storing vegetables, thereby achieving the intended purpose of freshening vegetables.
