detailed description

The present invention will be described in detail below with reference to the drawings and specific embodiments.

It has been found that after the dormant product, the aquatic product maintains its dormant freezing point temperature and provides suitable oxygen, humidity, and timely excretion of excrement, so that the aquatic product can be kept without water for a long time. In addition, different aquatic products require different keep-alive conditions.

Referring to FIG. 1 to FIG. 18, the present invention provides a keep-alive device 100 capable of creating a suitable environment for aquatic products to keep alive in a water-free state, and realizing a long life keeping of the aquatic product in a non-aqueous state. The keep-up device 100 may be used alone or in a refrigerating appliance 200 such as a refrigerator 200 or a freezer, and may be used as a part of the refrigerating appliance 200 for a user. Of course, the keep-alive device 100 in the refrigerating appliance 200 can also be used to store other items when the aquatic product is not required.

The keep-up device 100 includes a keep-up box 10 for keeping alive aquatic products, a temperature control module (not shown) for controlling the temperature inside the keep-alive box 10, and a humidity control module for adjusting the humidity in the keep-alive box 10. 20. An air control module 30 that adjusts the oxygen concentration in the containment tank 10, a drain mechanism 40 that excludes the aquatic product excrement, and a control system. The temperature control module, the wet control module 20, and the air control module 30 are all electrically connected to the control system (not shown) and are uniformly controlled by the control system.

The temperature control module controls the temperature within the containment tank 10 to reach and maintain a freezing point temperature of the aquatic product that needs to be kept alive. The temperature control module includes a refrigeration component that supplies a cooling capacity to the heat retaining box 10, a temperature control system electrically connected to the control system to control an operating state of the refrigeration component, and is electrically connected to the temperature control system. A temperature sensor within the containment tank 10. The refrigeration assembly is cooled by a cold storage package, a semiconductor refrigeration element, an air cooling system, or a direct cooling system. When the temperature sensor detects that the temperature is too high, the refrigeration assembly provides refrigeration to the keep-up tank 10 such that the temperature within the containment tank 10 is reduced to and maintained at a corresponding freezing point temperature of the aquatic product.

Referring to FIG. 1 to FIG. 18 , the air control module 30 includes an oxygen supply port 31 and an exhaust port 33 disposed on the heat retaining box 10 , and is respectively connected to the oxygen supply port 31 and the exhaust port 33 . Oxygen supply system 32 and exhaust system 34. The use of the oxygen supply system 32 in conjunction with the exhaust system 34 enables the gas within the containment tank 10 to maintain a certain oxygen concentration to meet the physiological requirements of the aquatic product. The aquatic product respiration generates carbon dioxide during the keep-alive process. Since the density of the oxygen is less than the density of the carbon dioxide, the oxygen supply port 31 is disposed higher than the exhaust port 33, so that the carbon dioxide component of the discharged gas is more than the oxygen component. Save oxygen and reduce costs.

Further, after the oxygen enters the keep-up box 10, the oxygen supply port 31 gradually diffuses into the keep-alive box 10 until the entire keep-alive box 10 is filled, so the oxygen-transporting port 31 and the The venting opening 33 is spatially diagonally disposed, that is, both are located on substantially diagonal lines of the accommodating space defined by the stagnation tank 10, which can better prevent oxygen from being discharged. In addition, when the refrigeration assembly is cooled by air cooling, in order to prevent oxygen from being discharged from the cold storage with the cold air circulation The outside of the 10 causes a decrease in the oxygen concentration, and an oxygen reverse osmosis membrane that prevents oxygen from being discharged is provided at the return air outlet.

The oxygen supply system 32 includes an oxygen delivery tube 321 connected to the oxygen delivery port 31, a gas source (not shown) connected to the other end of the oxygen delivery tube 321, and is connected between the oxygen delivery tube 321 and the gas source. An oxygen valve (not shown) that controls the amount of oxygen supplied. The exhaust system 34 includes an exhaust pipe 341 connected to the exhaust port 33, and an exhaust pump 342 connected to the exhaust pipe 341; both the oxygen valve and the exhaust pump 342 are controlled by a control system. The gas source is an oxygen cylinder, an oxygen generating device, etc., and the gas supplied by the gas source is pure oxygen, oxygen-rich gas, dry oxygen or humid oxygen.

In order to accurately control the oxygen concentration in the keep-up tank 10, the air control module 30 further includes an oxygen sensor (not shown) provided in the keep-up tank 10, and an oxygen sensor in the keep-up tank 10 (not shown), when it is detected that the oxygen concentration is too low, the oxygen valve is opened, and the oxygen delivery pipe 321 delivers oxygen to the inside of the keep-up tank 10 through the oxygen supply port 31; meanwhile, the exhaust pump 342 is opened to make water The dirty gas such as carbon dioxide discharged from the product is discharged from the inside of the keep-up tank 10, on the one hand, it is easy to update the gas in the keep-up tank 10, and on the other hand, the air pressure in the keep-up tank 10 can be relatively stabilized. Of course, if the air control module 30 does not include an oxygen sensor, time control can be directly added to the control system, and the oxygen delivery pipe 321 can be controlled to deliver oxygen or the exhaust pipe 341 to exhaust the exhaust gas according to the storage time timing, and the object of the present invention can also be achieved.

Referring to FIG. 12 to FIG. 14 , the wet control module 20 includes a water storage box 21 disposed in the heat retaining box 10 , and has a high moisture absorption, volatile and antibacterial function in the water storage box 21 . Block 22; the moisturizing block 22 is partially exposed in the keep-up case 10, so that water adsorbed from the water storage box 21 can be volatilized into the keep-up case 10 to maintain the keep-alive box Humidity within 10. The moisturizing block 22 is synthesized from a highly water-absorptive fiber and an antibacterial material, and is formed into a special structure to allow moisture to rapidly diffuse into the air.

The water absorbing property of the water absorbing fiber is a property of the fiber absorbing liquid phase moisture, and is copolymerized with the hydrophilic monomer to make the fiber forming polymer hydrophilic. It mainly depends on the number and type of hydroxyl groups (-OH), amino groups (–NH2), amide groups (–CONH–), carboxyl groups (–COOH), through which hydrogen bonds are established to associate with water molecules. The water molecules lose their thermal activity and temporarily remain on the fibers. When a hydrophilic group exists in the macromolecular chemical structure of the fiber, they can form a hydrate with the water molecule, and by chemically modifying the cellulose, the strongly hydrophilic carboxyl group is introduced into the large portion of the cellulose. By performing carboxymethylation, a water absorbing fiber having a water absorption ratio of 10 times or more can be obtained, which is 3 times more than a general superabsorbent material;

It also depends on the micropores, gaps and capillary pores between the fibers. The formation of microporous structures can double the specific surface area, rely on van der Waals force to adsorb water molecules through surface effects, and absorb and transfer through capillary effects. Moisture. The surface of the fiber has a groove or a cross-section, which not only increases the surface area, but also increases the moisture absorption on the surface of the fiber, and also increases the moisture retained by the capillary gap between the fibers. Therefore, the water-absorbing rate of the shaped fiber and the surface-concave fiber is higher than that of the same component. A smooth, round-section fiber. In addition to the direct absorption of moisture by the hydrophilic groups in the fibers, the water molecules that have been absorbed, because they are also polar, may interact with other water molecules. In this way, the water molecules that are later absorbed accumulate on the first batch of water molecules, forming a multi-layer molecular sorption, called indirect sorption of water molecules.
