Priority is claimed on Japanese Patent Application No. 2013-019603, the entire disclosure of which is hereby incorporated herein in

[Technical Field]

The present invention relates to refrigerator equipment technology, and more particularly to a refrigerator.

 【Background technique】

Currently, the refrigerator compartment of a refrigerator is usually provided with a shelf that divides the refrigerator compartment into a plurality of storage compartments for placing articles.

In the prior art, air is circulated between the storage chambers, so that the food placed in each storage chamber is prone to odor, and in the case of frequent opening and closing, the temperature in the refrigerating chamber is obvious. Rising, frequent temperature changes will shorten the shelf life of food, and even cause food to deteriorate. At the same time, due to the increase in temperature, the power consumption of the refrigerator will increase.

 [Summary of the Invention]

The invention provides a refrigerator to improve storage quality of articles and reduce power consumption.
