Embodiment 1

[0063] The present invention proposes a gas concentration regulatory scheme to achieve linkage control of the gasometric membrane and the oxygenated apparatus (nitrogen oxygen separation film assembly) according to the carbon dioxide concentration in the drawer, thereby ensuring that the carbon dioxide concentration in the drawer is in a relatively suitable range. To reach the inhibitory fruit and vegetables aerobic breathing, avoid damage caused by the oxygen-free breathing of fruits and vegetables, avoiding the purpose of condensation. The structure of the preservation refrigerator according to the present invention will be described below.

[0064] Compared to conventional air-conditioning film preservation drawers, the present invention is provided with an aerosoning apparatus (nitrogen oxygen separation membrane assembly) in the structure of a fresh-keeping refrigerator, and an air conditioning film is provided, so that oxygen in the air can pass through The air conditioner e...

Embodiment 2

[0083] Based on the preservation refrigerator described in the above embodiment, the present embodiment provides a gas concentration regulator of the refrigerator. Figure 4 It is a flow chart of a gas concentration regulatory method according to an embodiment of the present invention, such as Figure 4 As shown, the method includes the following steps:

[0084] Step S401, in the drawer closing, monitor the carbon dioxide concentration in the drawer;

[0085] Step S402, according to the interval in which the carbon dioxide concentration is located, the corresponding adjustment strategy is performed to adjust the gear position of the vacuum pump in the vacuum pump in the nitrogen oxygen separation membrane module and the gear film in the gas mask module; wherein the vacuum pump and the air conditioner The initial gear is an intermediate gear. Different gears of the vacuum pump correspond to different gas flow, and different gear positions of the gasometric membrane correspond to diff...

Embodiment 3

[0111] The technical solutions of the present invention will be described in detail below by specific embodiments and drawings. Figure 5 It is a detailed flow chart of the gas concentration regulation method of the refrigerator according to the embodiment of the present invention, such as Figure 5 As shown, the process includes the following steps:

[0112] Step S501, the user opens the gas transfer function based on the requirements.

[0113] Step S502, whether the drawer is integrated;

[0114] Step S503, if the drawer is not hit, the user is prompted to close the drawer.

[0115] In step S504, if the drawer is tight, the vacuum pump is turned to the L2 file, and the air conditioner is opened to the S2 gear.

[0116] In this embodiment, the vacuum pump is provided with two gears according to the flow, respectively, respectively, respectively, and the flow rate L1 2 , S2 = 450cm 2 , S3 = 650cm 2 .

[0117] Step S505, identify the inner carbon dioxide concentration C by carbon diox...

Abstract

The invention discloses a gas concentration regulation and control method of a refrigerator and the fresh-keeping refrigerator. The method comprises the steps of when a drawer is in a closed state, monitoring the concentration of carbon dioxide in the drawer; and according to the interval where the concentration of the carbon dioxide is located, executing a corresponding adjustment strategy so that the gear of a vacuum pump in a nitrogen-oxygen separation membrane assembly and the gear of a controlled atmosphere membrane in an adjustable controlled atmosphere membrane assembly are adjusted, wherein the initial gear of the vacuum pump and the initial gear of the controlled atmosphere membrane are both middle gears. According to the gas concentration regulation and control method of the refrigerator and the fresh-keeping refrigerator, linkage control over the controlled atmosphere membrane and the nitrogen-oxygen separation membrane assembly can be achieved according to the concentration of the carbon dioxide in the drawer, and whether the rotating speed of the vacuum pump and the effective use area of the controlled atmosphere membrane need to be adjusted or not can be judged according to the concentration of the carbon dioxide in the drawer; it is ensured that the concentration of the carbon dioxide in the drawer is proper while the concentration of oxygen in the drawer is reduced; and aerobic respiration of fruits and vegetables can be effectively inhibited, and damage caused by anaerobic respiration of the fruits and vegetables is avoided.

Description

Technical field [0001] The present invention relates to the technical field of refrigerator, in particular, to a gas concentration regulation method of a refrigerator and a preservation refrigerator. Background technique [0002] With the continuous improvement of living standards, the improvement in the diet structure, people's newness of fruits and vegetables are getting higher and higher, but not only require fruits and vegetables to remain fresh, but also require the nutrients of fruits and vegetables to maximize Reserved. [0003] At present, the air-conditioning technology is generally capable of meeting people's needs, which is mainly divided into active airline and passive angle. Among them, the active air conditioning is usually adjusted by adjusting the oxygen and carbon dioxide concentration in the fruit and vegetable drawer to increase the carbon dioxide concentration by reducing the oxygen concentration in the storage environment, thereby inhibiting the effect of fru...
