Food material fresh-keeping cabinet capable of improving indoor environment

Abstract

The invention discloses a food material fresh-keeping cabinet capable of improving indoor environment. The fresh-keeping cabinet comprises a fresh-keeping cabinet body and a case, wherein a hollow fiber membrane, a compressor, a capillary pipe, a dehumidification silencer, a suction filter, an air suction pipe, an oxygen exhaust pipe and a nitrogen exhaust pipe are arranged in the case; the hollowfiber membrane is used for separating oxygen and nitrogen from introduced air; a nitrogen exhaust port, used for exhausting nitrogen, of the hollow fiber membrane is connected with a nitrogen exhaustopening in a fresh-keeping chamber of the fresh-keeping cabinet body through the nitrogen exhaust pipe, and the nitrogen is conveyed to the fresh-keeping chamber; the capillary pipe is arranged on the nitrogen exhaust pipe; the capillary pipe injects high-concentration nitrogen discharged from the hollow fiber membrane into the fresh-keeping cabinet body at a certain pressure; the hollow fiber membrane is connected with the air suction pipe and sucks air through the air suction pipe; and the suction filter, dehumidification silencer and compressor are sequentially installed on the air suctionpipe from outside to inside. By applying the fresh-keeping cabinet, oxidation of food can be more effectively inhibited, and high-concentration oxygen can be generated, so that the comfortable indoorliving environment of a user is kept.

Description

Technical field [0001] The invention relates to the technical field of manufacturing fresh-keeping cabinets, in particular to improving indoor environment and fresh-keeping cabinets for food materials. Background technique [0002] In the prior art, the food preservation cabinet is usually equipped with a circulation fan and an evaporator at the back of the preservation room, and the performance of the food is realized by reducing the temperature. The actual working conditions are as follows: [0003] First, the cold air passing through the heat exchanger relies on the circulation fan to circulate the inside of the fresh-keeping compartment, and then is injected into the cold-air circulation channel through the cold air inlet located in the fresh-keeping compartment. [0004] Then, the cold air passing through the cold air circulation channel moves along the cold air circulation channel located behind the fresh-keeping compartment, and then circulates to the evaporator through the co...
