Problems solved by technology

However, when stored for a long time, it is considered that the quality deteriorates even in the freezing temperature zone
Thus, for example, if the user forgets to store food such as meat or fish in the storage container for about a week due to various things, the quality will deteriorate and the food will have to be discarded.

Abstract

The invention provides a refrigerator, wherein the oxidative deterioration and the corrosion of the nutrient components of food stored in a depressurized storage chamber for a long time due to microorganisms can be avoided. The refrigerator comprises a cooling unit (180) used for keeping the temperature of a depressurized storage chamber (24) at a preset value; and a control unit (100) used for outputting control signals to the cooling unit (180) so as to set the temperature of the depressurized storage chamber (24) at the preset value.

Description

technical field [0001] The present invention relates to a refrigerator, in particular to a refrigerator provided with a decompression storage room. Background technique [0002] As a conventional refrigerator, there exists a refrigerator shown in Unexamined-Japanese-Patent No. 2011-58670 (patent document 1). The refrigerator controls the food storage container to a low-oxygen state, thereby maintaining the freshness of the food inside the container. [0003] Patent Document 1: Japanese Unexamined Patent Publication No. 2011-58670 [0004] In the refrigerator described in the above-mentioned patent document, the food stored in the storage container can be indirectly cooled in a depressurized state, and thus is effective for preventing oxidative deterioration and drying of the food. However, when stored for a long time, the quality is considered to be deteriorated even in the freezing temperature zone. Therefore, for example, if the user forgets to store food such as meat o...
