Embodiment approach 1

[0019] Implementation mode 1: Such as figure 1 As shown in the structural diagram of the preservation room with cold storage device and oxygen increasing device, 100 valve, 101 oxygen concentration sensor, 102 controller, 103 reversing valve, 104 air supply device, 105 elastic positioning device, 106 reversing valve, 107 Ventilation and oxygenation device, 108 sliding door, 109 fixed door, 110 cold storage device, 111 pipeline, 112 pipeline, 113 pipeline, 114 pipeline, 115 electromagnetic flow control valve, 116 dirt collection tank, 117 dirt separation plate, 118 hollow porous diversion board, 119 dissolved oxygen concentration sensor, 120 temperature sensor.

[0020] The internal circulation oxygenation means that the air supply device sucks the air in the preservation room, forms bubbles in the water, and increases the dissolved oxygen concentration in the water; the 102 controller detects the 101 oxygen concentration sensor, the 119 dissolved oxygen concentration sensor...

Embodiment approach 2

[0024] Embodiment 2 : The general cold room is equipped with a ventilation and oxygenation device for experimental testing. Such as image 3 As shown in the structural diagram of the oxygen increasing device installed in the ordinary cold room, 300 valve, 301 oxygen concentration sensor, 302 controller, 303 reversing valve, 304 air supply device, 305 elastic positioning device, 306 valve, 307 ventilation and oxygen increasing device, 308 sliding door, 309 fixed door, 310 pipeline, 311 pipeline, 312 pipeline, 313 exhaust gas, 314 intake pipeline, 315 aquatic product, 316 sewage collection tank, 317 sewage separation plate, 318 hollow porous deflector, 319 dissolved oxygen Concentration sensor, 320 temperature sensor. The 302 controller detects the value of the 319 dissolved oxygen concentration sensor, and judges whether to ventilate and increase oxygen according to the stored dissolved oxygen concentration required for the variety to keep alive. When external circulation ox...

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.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a household refrigerator. Background technique [0002] Aquatic products mainly include fish, shrimp and crab, shellfish, algae, special aquatic products and processed aquatic products. The production methods mainly include fishing and breeding, using ocean and inland waters for production, farmed fish are consumed in fresh form, caught products are consumed in the form of frozen products, and algae are consumed in the form of processed products. Fish are rich in nutrients, poor in skin protection, strong in enzyme activity, and contain a large number of spoilage bacteria on the surface of fish body, gills and digestive system. After the fish body is stiff, it begins to soften gradually and loses its elasticity. This is the result of the self-decomposition of the fish body by various enzymes contained in the fish body. This change is called autolysis. Although the autolyz...
