Abstract
The invention relates to the technical field of refrigeration, in particular to a household refrigerator. An intelligent alive-keeping household refrigerator with an aerator comprises a controller, an oxygen concentration sensor, a dissolved oxygen concentration sensor, an air supply device, a heat exchanger and a reversing valve, wherein the controller detects the numerical value of the dissolved oxygen concentration sensor; and when needed, inner circulating aeration or outer circulating aeration is carried out, the fluctuation of the concentration of dissolved oxygen in water is kept in a preset interval, and the alive-keeping time of an aquatic product is prolonged. Inner circulating aeration is carried out in a manner that air sucked into an alive-keeping chamber by the air supply device forms air bubbles in water and increases the concentration of dissolved oxygen in water. As the inner space of the alive-keeping chamber is limited, through inner circulating aeration, the concentration of oxygen in the air still decreases, but the concentration of carbon dioxide increases. Outer circulating aeration is carried out in a manner that an air change device of the alive-keeping chamber, additionally arranged, introduces external fresh air into the alive-keeping chamber, changes heat at the same time and forms air bubbles in water, thereby increasing the quantity of dissolved oxygen in water and the oxygen content in the air in the alive-keeping chamber.
