Abstract

The invention discloses refrigerator equipment adopting nitrogen for retaining freshness and outputting oxygen. The refrigerator equipment comprises a refrigerator main body and a case connected withthe refrigerator main body. An ultrathin film, a vacuum pump, a silencer, a fan, an oxygen discharging pipe and a nitrogen discharging pipe are arranged in the case. The ultrathin film is used for introducing air and separating oxygen and nitrogen in the air. An oxygen discharging port, used for discharging oxygen, of the ultrathin film discharges oxygen through an oxygen discharging port of the refrigerator main body via the oxygen discharging pipe. The vacuum pump and the silencer are arranged on the oxygen discharging pipe. A nitrogen discharging port, used for discharging nitrogen, of theultrathin film is connected with a nitrogen discharging port in a refrigerating chamber of the refrigerator main body through the nitrogen discharging pipe, and nitrogen is conveyed to the refrigerating chamber. The fan and a corresponding capillary pipe are arranged on the nitrogen discharging pipe, and nitrogen is conveyed to the refrigerating chamber at certain pressure through the rotating force of the fan. According to the refrigerator equipment, a refrigerator can more effectively restrain stored fruits, vegetables and other food from being oxidized, the freshness retaining time is prolonged, high-concentration oxygen can be generated, and therefore a comfortable indoor living environment is maintained for users.

Description

technical field [0001] The invention relates to the technical field of refrigerator manufacturing, in particular to refrigerator equipment that adopts nitrogen to keep fresh and outputs oxygen. Background technique [0002] In the prior art, the main body of the refrigerator is divided into a freezer compartment and a refrigerator compartment. A circulation fan and an evaporator are respectively installed behind the freezer compartment. Vegetable boxes are installed at the lower end of the freezer compartment. The actual working conditions are as follows: [0003] First, the cold air passing through the heat exchanger is circulated inside the freezing chamber by the circulation fan, and then injected into the cold air circulation channel through the cold air inlet of the freezing chamber located below the freezing chamber. [0004] Then, the cold air passing through the cold air circulation channel moves along the cold air circulation channel at the rear of the refrigerating...
