In addition, in the time will taking out the vegetables in the vegetable container 30, the light freeze box 31 that will be positioned at vegetable container 30 tops is pushed the depths to.So, the pulley that the pulley 33 that is arranged on light freeze box 31 bottom surfaces just forms from the internal face of vegetable container 30 is deviate from the retainer 34 that strengthens rib 32 and is slided with strengthening rib 32 at pulley, and be positioned and the position of pulley as shown in figure 12, with end, the depths butt that strengthens rib 32.Under this state, upper side tegmentum 36 complete closed of light freeze box 31.
In addition, the lid 36 of light freeze box 31 for closed state or half opening-wide state under with light freeze box 31 when move the depths, as shown in figure 13, guide portion 41 that forms on the light freeze box 31 and guide portion 42 butts that cover formation on 36, so along with light freeze box 31 to the moving of depths, lid 36 moves to the depths along interior case strip bulge 43.
And, in case vegetable container 30 is moved to the depths for vegetable container 30 is positioned in the vegetable compartment 3, vegetable container 30 just moves to the depths under the state that light freeze box 31 stops, pulley 33 at light freeze box 31 is positioned on the position of pulley with the rearward end of the retainer 34 that strengthens rib 32 of vegetable container 30, and light freeze box 31 just is positioned in the vegetable compartment 3 in the lump with vegetable container 30.
Adopt this example, cooling unit 53 also is provided with independently R evaporimeter 26 except F evaporimeter 51, the vegetable compartment 3 that is communicated with it is set below refrigerating chamber 2 simultaneously, and when finishing, continues the R refrigerating mode running of R fan 28 at the appointed time, the frost that is attached on the R evaporimeter 26 is evaporated at short notice, i.e. execution adds wet model, so can improve the cold air humidity that circulation is carried in refrigerating chamber 2 and vegetable compartment 3.Thereby the structure that covers the vegetable container upper side with traditional usefulness poisture-penetrability lid is compared, and can omit the poisture-penetrability lid, reduces the cost of vegetable container 30, has omitted simultaneously the required space of poisture-penetrability lid is set, and can improve the space efficiency of vegetable compartment 3.
