体７が密接して設けられている。Conventional technology Traditionally, vegetable containers were installed in refrigerators to prevent deterioration of freshness in the open air environment (particularly shrinkage due to dryness and high-temperature damage) and preserve vegetables for as long as possible. It is common practice to accommodate the This conventional example will be explained below with reference to FIG. Reference numeral 1 denotes a refrigerator body, which is divided by a partition wall 2 into a freezer compartment 3 at the top and a refrigerator compartment 4 at the bottom. 6 is a door provided opposite to the refrigerator compartment 4. Further, 6 is a vegetable container provided at the bottom of the refrigerator compartment 4. A glass lid 7 around which a rubber gasket is disposed is provided in close contact with the upper opening surface of the vegetable container 6.

量を超えては貯蔵出来ないという問題点も有していた。Problems to be Solved by the Invention However, in the above-mentioned configuration, since the structure is mostly closed, the water vapor evaporating from the vegetables 8 is absorbed into the inner surface of the vegetable container 6 and the glass lid 7. Dew condensed and adhered to the inner surface. This is because the outer surfaces of the vegetable container 6 and the lid 7 are cooled by the cold air convecting inside the refrigerator compartment 4, and -
However, the temperature inside the vegetable container 6 is high due to the respiratory heat of the vegetables 8.
This is because a temperature difference occurs between the inside and outside of the surfaces of the vegetable container 6 and the lid 7. Water droplets adhering to the inner surfaces of the vegetable container 6 and the lid 7 fall by natural fall or due to vibrations when the vegetable container 6 is attached and removed, and are deposited on the surface of the stored vegetables 8 and the bottom of the vegetable container 6. There was a problem that the vegetables 8 would be damaged due to accumulation, and in severe cases, it would lead to rotting, so in reality, the period that the vegetables 8 could be stored in a fresh state was not that long.
Apart from this, the vegetable container 6 is fixed at a predetermined position in the refrigerator compartment 4 together with its lid 7, and is generally used exclusively for vegetables. There is also the problem that even if one wants to store a large amount of vegetables, it is not possible to store more than the capacity of the provided vegetable container 6.
