Example Embodiment

[0019] The present invention will be further described below in conjunction with the embodiments shown in the drawings.

[0020] See figure 1 The refrigerator body 1 according to an embodiment of the present invention includes three parts: a refrigerating compartment 2, a freezing compartment, and a temperature changing room. Among them, the refrigerator compartment 2 has a specific preservation system, which is composed of a preservation box 3, an oxygen-enriched membrane 4, a vacuum pump 5, a first air pipe 6, a pressure sensor 7, a control board 8, and a second air pipe 11. The fresh-keeping box 3 is fixed in the freezer compartment of the refrigerator. The fresh-keeping box 3 has an oxygen-enriched film 4 built in. In principle, the oxygen-enriched film is fixed on the inner wall of the fresh-keeping box, except for the door. can. The oxygen-enriched membrane 4 is connected to the suction port of the vacuum pump 4 fixed on the outside of the fresh-keeping box 3 through the f...

Abstract

The invention relates to an ultra-long-term freshness preserving system which can be applied to a refrigerator and installed in a refrigerating chamber of the refrigerator. The system comprises a freshness preserving box, an oxygen enriching membrane, a vacuum pump, a pressure sensor, a control plate and gas delivering pipes, wherein the oxygen enriching membrane is fixed in the freshness preserving box and connected with a gas sucking opening of the vacuum pump by the first gas delivering pipe penetrating through the wall of the freshness preserving box; an exhaust opening of the vacuum pump is led outside a box body for mounting the ultra-long-term freshness preserving system by the second gas delivering pipe; the pressure sensor is fixed to the first gas delivering pipe to sense the pressure in the freshness preserving box, and a signal line is connected with the control plate; and the control plate is connected with and controls the vacuum pump. The invention has ultrastrong freshness preserving function and can effectively improve the storing time of food stored in the refrigerator by being applied to the refrigerator; compared with the refrigeration of a common refrigerator, the invention is expected to be improved by 2-3 times. In addition, the invention can provide high-concentration oxygen for a room, has a plurality of advantages and practical values, and greatly improves the practicability and the healthy performance of the refrigerator.

Description

technical field [0001] The invention belongs to the field of food preservation and relates to a food preservation system. Background technique [0002] Along with the raising of people's living standard, electric refrigerator is very popular. It mainly includes a freezer and a cold room.
