Description

A kind of refrigerator

Technical Field

The utility model relates to a refrigeration plant technical field especially relates to a refrigerator.

Background

The refrigerator is a refrigerating device which keeps constant low temperature, and is also a household appliance which keeps food or other articles in a constant low-temperature cold state. With the improvement of life quality, the requirements of consumers on the preservation of stored foods are higher and higher, and especially the requirements on the color, the taste and the like of the foods are higher and higher.

Research shows that the respiration of animals and plants, the growth and reproduction of oxygen consuming microorganisms, the oxidation and the like are closely related to the oxygen concentration. With the decrease of the oxygen concentration, the respiration and metabolic reactions of the plants are weakened, and even the plants enter a dormant state; the life activities of some pests and microorganisms are inhibited, and the growth and the reproduction are weakened or even stopped; the oxidation is reduced. Thereby effectively reducing the consumption of nutrient substances of fruits and vegetables and delaying the maturity and aging of fruits; the growth and the propagation of pests and microorganisms are reduced, and the occurrence of plant diseases and insect pests and rot is inhibited; the oxidative deterioration of some nutrient components, the oxidative discoloration of fruits and the like are reduced, and the fresh-keeping period of fruits and vegetables is effectively prolonged.

During the period that the fruits and vegetables are placed in the refrigerator for storage after being picked, life activities such as respiration and metabolism are still carried out, the respiration of the fruits and vegetables is inhibited and the metabolism process of the fruits and vegetables is delayed by controlling conditions such as temperature and oxygen concentration in the refrigerator, the freshness and commodity of the fruits and vegetables are better kept, and the storage period and the preservation period of the fruits and vegetables are prolonged. In the existing refrigerator on the market, the gas exchange and oxygen removal are performed in a mode that the gas-regulating membrane assembly is arranged at the top of the gas-regulating fresh-keeping drawer seat, so that the thickness of the drawer seat is thicker, and more mounting space is occupied in the vertical direction. And the air pump is connected with the air delivery pipeline through a long air delivery pipeline, so that the defects of difficult heat dissipation, difficult replacement, resonance with the compressor and the like exist. For example, arranging the suction pump at the top of the refrigerator and the press compartment requires long air transmission pipelines, which reduces the reliability of the system; the problems that the heat is difficult to dissipate at high temperature, the resonance is easy to generate with the press and the like are also faced in the press bin; the arrangement of the foaming layer can affect the heat preservation performance of the refrigerator, the heat dissipation of the air pump is difficult, and the replacement is difficult once the air pump is damaged.
