[Problems to be Solved by the Invention] However, the conventional temperature setting in the vegetable compartment is an intermediate setting between the proper storage temperatures for all the vegetables and fruits, and although it can be applied to all vegetables and fruits, optimum storage conditions are required. It is hard to say that In other words, the temperature is too high for leafy vegetables and the like that are to be preserved at low temperatures near the freezing point, and conversely the temperature is lower for those that are prone to low temperature damage. In order to preserve higher quality, it is necessary to set detailed conditions suitable for each vegetable and fruit.

In view of the above problems, the present invention provides a refrigerator that freshly preserves each vegetable and fruit for a longer period of time by making the preservation temperature and humidity in the vegetable container closer to appropriate conditions.

[0012]

A refrigerator according to the present invention for solving the above-mentioned problems divides a vegetable container of the refrigerator into two compartments, an upper compartment is 0 to 2 ° C and a lower compartment is 6 to 7 ° C. The internal temperature is set so that the upper compartment can move backward.

The partition wall between the upper compartment and the lower compartment is made of a substance having a humidity control function.

Further, at the rear of the lower compartment, a temperature of 10
A section set to -12 ° C is provided.

[0015]

The present invention divides the inside of a vegetable container according to temperature so that those suitable for low-temperature preservation are particularly suitable for low temperature storage, and those that are prone to low temperature damage are relatively high temperature storage compartments (hereinafter Stored in "medium temperature compartment")
It becomes possible to make detailed correspondences such as preservation, depending on the type and characteristics of vegetables and fruits, and as a result, it becomes possible to preserve higher quality.

Further, by forming the partition wall between the two compartments with a substance having a humidity adjusting function, it is possible to prevent excessive humidity and insufficient humidity in both compartments.

Furthermore, by using the exhaust heat of the compressor, by providing a compartment with a higher temperature in the rear part of the above-mentioned middle-temperature compartment, it is particularly difficult to control the temperature of vegetables and fruits that are prone to low temperature disorders and other vegetables. -It becomes possible to store tropical fruits such as bananas and pineapples that were difficult to store together with fruits.
