Problems solved by technology

However, a plurality of refrigerating chambers of this fresh-keeping refrigerator are connected to each other, and its air-conditioning system is ventilated through the same air inlet and the same air outlet. The oxygen content in the refrigerator rises, and after the refrigerator door is closed, it is necessary to reduce the oxygen in all the refrigerators, which consumes more energy. In add

Embodiment 1

[0020] Embodiment one: if figure 2 As shown, a fresh-keeping refrigerator 1 of the present invention includes several storage chambers, and each storage chamber has an air inlet and an air outlet respectively, the air outlet is at the upper end of the storage chamber, and the air inlet is at the upper end of the storage chamber. This is because nitrogen is lighter than oxygen. When the fresh-keeping gas that is charged, that is, nitrogen-rich gas enters the storage room through the air inlet, the nitrogen will float upwards, and the air above is continuously pumped away, thereby quickly achieving gas replacement. the goal of. Such as figure 2 Two storage chambers 41 and 42 have been drawn as shown, the storage chamber 41 has an air outlet a1 and an air inlet b1, the storage chamber 42 has an air outlet a2 and an air inlet b2, and the air outlet a1 and a2 are in the storage area. The upper end of the chamber, the air inlets b1, b2 are at the bottom end of the storage chambe...

Embodiment 2

[0028] Embodiment two: because the gas in the storage chamber 41 and 42 contains odor, organic gas and moisture, removing these gases is conducive to the fresh-keeping of food and the purification of the gas in the storage chamber, so on the basis of embodiment one, Such as image 3 As shown, there is an odor and organic gas detachment device 9 connected between the gas distributor 8 and the nitrogen-oxygen separation device 13, and the odor and organic gas outlets e1 and e2 of the gas distributor 8 are connected to the odor and organic gas detachment device 9. The gas inlet, the gas outlet of the odor and organic gas detachment device 9 is connected to the gas inlet k of the nitrogen and oxygen separation device 13 . The gas coming out from the storage chamber 41 or 42 and the gas distributor 8 is sent to the nitrogen and oxygen separation device 13 after passing through the odor and organic gas detachment device 9 to remove the odor, organic gas and moisture. The odor and o...

Abstract

The invention relates to a system control method for a refrigerator, in particular to a method for controlling a gas adjusting system of a fresh-keeping refrigerator. The method comprises the following steps that: when oxygen concentration sensors in storage chambers sense that the oxygen concentration in one or more of the storage chambers is greater than a set value, the oxygen concentration sensors transmit signals to a controller; the controller controls a compression pump to work according to the signals transmitted by the oxygen concentration sensors, and controls a gas distribution device to be communicated to the storage chambers in which fresh-keeping gas is needed to be supplemented; and when the oxygen concentration sensors sense that the oxygen concentration in all the storage chambers is equal to or smaller than the set value, the oxygen concentration sensors transmit signals to the controller, and the controller controls the compression pump to stop working. By the method for controlling the gas adjusting system of the fresh-keeping refrigerator, requirements of different foods with different fresh-keeping gas adjusting parameters can be met, the best fresh-keeping effects on different foods are achieved, each closed storage chamber is independently controlled, and gas in the storage chamber can be independently replaced; and the method has the advantages that the fresh-keeping time is prolonged, fresh-keeping quality is upgraded, energy consumption is reduced, and cross-contamination of the foods is reduced.

Description

technical field [0001] The invention relates to a system control method of a refrigerator, in particular to an air conditioning system control method of a fresh-keeping refrigerator. Background technique [0002] At present, refrigerators (freezers) used in households or shopping malls to keep food fresh mainly use cooling technology to create a low-temperature fresh-keeping environment in the refrigerator or freezer to keep food fresh. Generally speaking, the lower the temperature, the longer the fresh-keeping time. long. But there are many deficiencies in this existing fresh-keeping mode. On the one hand, the longer the fresh-keeping time is, the lower the required temperature will be, thus wasting energy; All kinds of smelly gases and organic gases that come out stay in the fresh-keeping environment for a long time and cannot be replaced, which not only causes cross-contamination of food, but also shortens the fresh-keeping time.
