Problems solved by technology

In addition, it is necessary to increase the size of the decompression device and increase the compressive strength of the frame constituting the decompression storage room, resulting in a reduction in food storage space and an increase in cost.
[0005] In addition, since the difference between the internal pressure of the storage container and the external pressure of the storage container is large when the decompression is released, there is a problem that the aluminum packaging of the sweets peels off, etc., resulting in the so-called so-called food that is limited in the decompression storage room.

Abstract

The invention provides a refrigerator, which can inhibit the nutrition components in the foodstuff contained in a pressure-reduction storage chamber from being oxidated and deteriorated in a long term. the refrigerator (1) comprises the pressure-reduction storage chamber (24) arranged in the refrigerator and having an internal pressure reduced to be lower than the atmospheric pressure, a deoxidizer (81) is arranged in the pressure-reduction storage chamber (24), the deoxidizer (81) is an antioxidant containing inorganic components and organic components, which is disposed in an antioxidant box (80), the antioxidant box (80) can prevent the air guided under the atmospheric pressure, the air guided under the condition that the antioxidant box (80) at lower pressure than the atmospheric pressure is more than the air guided under the condition that the antioxidant box (80) at the atmospheric pressure, to reduce the oxygen in the pressure-reduction storage chamber (24).

Description

technical field [0001] The present invention relates to a refrigerator using an oxidation suppressing case for suppressing oxidative deterioration of nutritional components contained in a storage room of the refrigerator. Background technique [0002] As a conventional refrigerator, there is a refrigerator described in Japanese Patent No. 4015687 (Patent Document 1). This refrigerator is provided with a decompression storage chamber which is airtight when food is stored, and is formed at a low pressure of 0.7 atmospheres. In this way, by reducing the pressure of the decompression storage chamber to 0.7 atmospheric pressure, the oxygen concentration in the decompression storage chamber can be reduced. Thereby, the nutrient component in the food accommodated in the decompression storage chamber is suppressed from combining with the oxygen in the air, and the oxidative deterioration of the nutrient component is prevented. [0003] [Patent Document 1] Japanese Patent No. 40156...
