Abstract

The invention relates to a preservation refrigerator and a matched oxygen concentration regulating device. The light oxygen reduction preservation refrigerator comprises a refrigerating chamber, an extraction port and an air injection port, the extraction port and the air injection port are communicated with the oxygen concentration regulating device by a corresponding extraction pipeline and an air injection pipeline, a main body of the device is an oxygen concentration regulator with the light response mode, the extraction pipeline is communicated with an air inlet of the oxygen concentration regulator, the air injection pipeline is communicated with an air outlet of the oxygen concentration regulator, electromagnetic valves are both connected on the extraction and the air injection pipelines in series, an air pump is connected on the pipeline of the extraction pipeline or the air injection pipeline within the electromagnetic valve in series, the oxygen concentration regulator, the electromagnetic valves and the air pump are connected with a control circuit. The mode utilizes the characteristics of oxygen absorption and oxygen release of the light response material under the radiation of the ultraviolet with the different wavelengths, the control is convenient, the regulation of the oxygen concentration and the oxygen reduction preservation refrigerator can be further realized by being matched with a simple control element.

Description

technical field [0001] The invention relates to fresh-keeping technology in the field of refrigeration technology, in particular to a fresh-keeping refrigerator, and also relates to a supporting oxygen concentration adjusting device. Background technique [0002] There are five factors causing food deterioration: 1 microbial action; 2 enzyme action; 3 oxidation; 4 respiration; 5 mechanical damage. Generally speaking, the lowering of temperature can delay and weaken their effects, but it cannot completely inhibit their effects, so the quality of refrigerated and frozen foods will always decline. In order to achieve the purpose of refrigerator food preservation, refrigerator preservation technology must be studied from four aspects: temperature treatment, microbial treatment, humidity treatment and gas adjustment. [0003] The oxygen content in ordinary air is nearly 21%, which is high, which is not conducive to food preservation. Oxygen is closely related to the oxidation a...
