Abstract

The present invention provides a refrigerator which realizes increase of food storing space and cost reduction, and can prevent oxidation deterioration of nutrition components in the food stored in a decompression storing chamber. The refrigerator is provided with an anti-oxidation component release box (80) with antioxidant at the inner part at the storing chamber formed in the refrigerator. Theanti-oxidation component release box (80) is configured to the inner part of the decompression storing chamber (24) which is closed and depressurized to a pressure state lower than the atmosphere in food storing. The antioxidant which releases the anti-oxidation component for a large amount in the pressure state lower than the atmosphere state is used.

Description

technical field [0001] The invention relates to a refrigerator. Background technique [0002] As such a conventional refrigerator, there is a refrigerator described in JP 2007-64620 A (Patent Document 1). In this refrigerator, an anti-oxidation release unit is disposed in a storage room opened to a space for circulating cold air in the refrigerator. The anti-oxidation unit is equipped with an antioxidant volatilized under atmospheric pressure, and the anti-oxidation component of the antioxidant is released into the refrigerator. The storage room, covering the food such as vegetables in the storage room, can prevent the nutrients in the food from combining with the oxygen in the air from being oxidized and decomposed and reduced. [0003] In addition, as another conventional refrigerator, there is a refrigerator described in Patent No. 4015687 (Patent Document 2). This refrigerator has a low-pressure chamber sealed at a low pressure of 0.7 atmospheres when food is stored. ...
