Embodiment approach 1

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

[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 controller (102) detects the oxygen concentration sensor (101), the dissolved...

Embodiment approach 2

[0024] Embodiment 2: Install a ventilating device in an ordinary cold storage room for experimental testing. Such as image 3As shown in the schematic diagram of the structure of the oxygen increasing device installed in the ordinary cold room, the valve (300), the oxygen concentration sensor (301), the controller (302), the reversing valve (303), the air supply device (304), the elastic positioning device (305 ), valve (306), breather (307), sliding door (308), fixed door (309), pipe (310), pipe (311), pipe (312), exhaust gas (313), air intake pipe (314), aquatic products (315), sewage collection tank (316), sewage separation plate (317), hollow porous deflector (318), dissolved oxygen concentration sensor (319), temperature sensor (320). The controller (302) detects the value of the dissolved oxygen concentration sensor (319), and judges whether to ventilate and increase oxygen according to the stored dissolved oxygen concentration required for the variety to keep alive. Wh...

Abstract

The invention relates to the technical field of refrigeration, in particular to a household refrigerator. An intelligent keep-alive household refrigerator with an oxygen increasing device includes a controller, an oxygen concentration sensor, a dissolved oxygen concentration sensor, an air supply device, a heat exchanger, and a reversing valve. The controller detects the value of the dissolved oxygen concentration sensor, and performs Oxygenation in internal circulation or external circulation keeps the concentration of dissolved oxygen in the water fluctuating within a set interval and prolongs the preservation time of aquatic products. The internal circulation oxygen enhancement is that the air supply device sucks the air in the living room, forms bubbles in the water, and increases the dissolved oxygen concentration in the water. The indoor space of the keep alive is limited, and the oxygen concentration in the air decreases and the carbon dioxide concentration increases after the internal circulation increases oxygen. The external circulation oxygen enhancement is to increase the ventilation device of the preservation room, exchange the fresh air outside the preservation room, and exchange heat at the same time, forming bubbles in the water, thereby increasing the dissolved oxygen in the water and the oxygen content in the air in the preservation room.

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...
