DETAILED DESCRIPTION

[0022] The specific implementation of a refrigerator with a deodorizing device provided by the present invention will be further described with reference to the accompanying drawings and embodiments.

[0023] like Figure 1 As shown, a refrigerator with a deodorizing device includes a refrigerator body, and the refrigerator body is provided with a refrigerating chamber 1, a micro-freezing chamber 2 and a freezing chamber 3 from top to bottom; wherein, the inner cavity of the refrigerating chamber 1 is provided with two side-by-side storage drawers 11; and a deodorizing device 4 is provided between the two storage drawers 11.

[0024] like Figure 2 As shown, the deodorizing device 4 includes a box body and a box cover 41 located on the top of the box body, and a sealing ring is also provided between the box body and the box cover 41. A water replenishment port 411 is provided on the box cover 41 to facilitate the replenishment of NaCl reaction liquid for the deodorizing device 4. A breathable membrane 42 is provided on the side wall of the box body close to the door of the cold storage chamber 1. It is worth noting that the breathable membrane is also called a microporous membrane, which is made of polymer materials (polymer powders such as high-density polyethylene, polypropylene, polytetrafluoroethylene, etc.) and has the effect of being only air-permeable but not water-permeable. A fixed groove is provided at the bottom of the inner cavity of the box body, and at least two groups of reaction components 43 are provided in the fixed groove. Preferably, the box body volume of the deodorizing device is 3L-20L; the diameter of the fixed groove is 200-400mm.

[0025] like Figure 3 As shown, the reaction assembly 43 includes an upper cover film 431 at the top and a bottom cover film 432 at the bottom. Preferably, the diameters of the upper cover film 431 and the bottom cover film 432 are both 150-330 mm. A plurality of reaction chambers 433 are vertically arranged between the upper cover film 431 and the bottom cover film 432. The diameter of the reaction chamber 433 is 1 mm-5 mm and the height is 8 mm-50 mm. Preferably, the reaction chamber 433 adopts a hollow cylindrical structure, and a reaction core is placed in the inner cavity of the reaction chamber 433. The shape of the reaction assembly can be diverse and is not limited to the one in the present invention. It can also be a hedgehog shape or other shapes, which is not a further limitation of the present invention.

[0026] Preferably, a slot is provided at the bottom of the reaction chamber 433 , and the reaction core is fixed in the inner cavity of the reaction chamber 433 through the slot.

[0027] Also preferably, a plurality of through holes are evenly distributed on the surfaces of the plurality of reaction chambers 433 , and the aperture of the through holes is 0.5-2 mm.

[0028] Further preferably, the box body of the deodorizing device is filled with a NaCl electrolyte solution with a concentration of 2%-10%. When in use, it is only necessary to regularly replenish the NaCl solution through the water replenishment port 411 or replace the consumed reaction core.

[0029] More preferably, the reaction core comprises a positive electrode material and a negative electrode material; common materials may be, but are not limited to, one of aluminum alloy, brass alloy, aluminum-zinc alloy, iron alloy, aluminum-nickel alloy, aluminum graphite or iron graphite;

[0030] Preferably, the metal activity is ranked as follows: (the most active one is used as the negative electrode, and the less active one is used as the positive electrode)

[0031] Mg (magnesium) > Al (aluminum) > Zn (zinc) > Fe (iron) > Sn (tin) > Pb (lead) > Cu (copper) > Ni (nickel)

[0032] The positive electrode material can be any one of magnesium, aluminum, zinc, iron, tin, lead, copper, nickel, inert materials and air; and the negative electrode material needs to be one that is more active than the positive electrode material, thereby forming a primary battery.

[0033] Example 1:

[0034] The reaction core is made of aluminum-nickel alloy, in which aluminum is the negative electrode and nickel is the positive electrode; the electrolyte is NaCl solution;

[0035] Aluminum loses electrons and undergoes oxidation reaction to generate aluminum ions, while the oxygen on the positive electrode gains electrons and reacts with water to generate hydroxide ions. This process can be represented by the following electrode reaction formula:

[0036] Oxidation reaction occurs at the negative electrode: 4Al-12e - =4Al 3+ , in this reaction, the aluminum atom loses 12 electrons and is oxidized into aluminum ions;

[0037] Reduction reaction occurs at the positive electrode: 3O2+6H2O+12e - =12OH - In this reaction, the oxygen molecule gains 12 electrons and reacts with water to form 12 hydroxide ions.

[0038] Example 2:

[0039] The reaction core is made of iron alloy, in which iron is the negative electrode and carbon is the positive electrode; the electrolyte is NaCl solution;

[0040] Oxidation reaction occurs at the negative electrode: Fe-2e-=Fe 2+ , in this reaction, the iron atom loses 2 electrons and is oxidized into iron ions;

[0041] A reduction reaction occurs at the positive electrode: O2+2H2O+4e-=4OH-. In this reaction, the oxygen molecule obtains 4 electrons and reacts with water to generate 4 hydroxide ions.

[0042] At present, most of the odors in refrigerators are organic substances, including alcohols, aldehydes, ketones, lipids, etc. The utility model provides an odor removal device and a reaction component. Through the redox reaction of the reaction core in the NaCl solution, the hydroxide ions generated will react with the odor molecules generated in each room through the circulating cold air in the air duct, thereby removing the odor in the refrigerator. The utility model has a simple structure, convenient operation, stable performance, can continuously remove odors for a long time, and can also be recycled, energy-saving and environmentally friendly. Compared with traditional odor removal equipment, it effectively extends the service life of the equipment and improves the user experience.
