The humidity of the moisturizing portion 211a can be controlled by the portion 211a via the moisture permeable membrane structure 24. In the present embodiment, the moisturizing portion 211a is for storing vegetables such as leafy vegetables having a high water loss rate. The material of the moisture permeable membrane structure 24 is exemplified by regenerated cellulose, but not limited by regenerated cellulose. However, when the moisture content of the hydrating portion 211a is higher than the preset humidity range, It means that the moisture content of the air in the moisturizing portion 211a can be borne by the non-leaf vegetables. At this time, the moisture in the moisturizing portion 211a is absorbed by the regenerated cellulose molecules through the air flow, and is removed to the outside of the moisturizing portion 211a to lower the moisturizing portion 211a. Humidity, on the other hand, if the humidity of the moisturizing portion 211a is lower than the preset humidity range, it means that the moisture content of the air in the moisturizing portion 211a is insufficient for the leafy vegetables to absorb, and the moisturizing property of the regenerated cellulose molecules will hinder the moisturizing portion.

Specifically, the cold air from the refrigerating chamber 111b enters the temperature-controlled moisturizing passage 214a along the air-permeable opening 131 by sedimentation. Since the position of the return air outlet 32 is adjacent to the air-permeable opening 131, the cold air rapidly follows. The temperature-controlled moisturizing passage 214a enters the first cooling passage 214b along the return air outlets 32 to reduce the flow to the door body 12, thereby maintaining the temperature of the vegetable and fruit chamber 111b.

The windshield unit 4 is disposed on the heat shield 133 of the first plate member 13. The windshield unit 4 includes a bottom surface disposed on the bottom surface of the first plate member 13 and adjacent to the second storage box 22. The top edge of the side wall is provided with a rear windshield 41 separating the gap 223 from the temperature control moisturizing passage 214a, and a top edge of the front side wall of the first storage member 22 disposed adjacent to the bottom surface of the first plate member 13 The rear windshield 41 shields the front windshield 42 that is open by the second storage case 22. Here, the top edge of the rear side wall refers to the top edge of the rear side wall portion of the second surrounding wall 222, and likewise, the top edge of the front side wall refers to the second side.

Of course, even if the windshield unit 4 is omitted, the cold air can be moved to the air return port 32, and the humidity and temperature of the vegetable and fruit chamber 111b can be maintained at the same time.

Furthermore, the number of storage boxes that can be accommodated in the vegetable compartment 111b is not limited to the first storage box 21 and the second storage box 22. In another embodiment, the vegetable compartment 111b can also be placed in a volume. a first storage box 21 substantially corresponding to the volume of the vegetable and fruit chamber 111b, that is, a top edge of the first surrounding wall 213 of the first storage box 21 is adjacent to the first plate member 13, and the front and rear side wall portions are adjacent to each other The front windshield 42 and the rear windshield 41 can also guide the cold air to the return air outlet 32 to further achieve the moisturizing effect of the vegetable and fruit setting space 211.
