Description
Technical field
This utility model relates to a kind of gas cleaning plant, in particular for removing the deodorizing sterilizing device of harmful gas composition in the cold compartment of refrigerator.
Background technology
The function of domestic refrigerator cold storing and fresh-keeping food brings great convenience for people's life.But,, leave wherein raw food and cooked food in the microorganism that contains pathogenic bacteria take place to be easy to generate when rotten because the gas in the cold room is hedged off from the outer world; Leave fresh fruit of vegetables product in the cold room in addition in and can discharge ethylene gas when further ripe.The former can pollute other fresh food of infringement, causes disease; The latter's existence then can be quickened the maturation process of fruit and vegetable food, makes freshness date shorten.Therefore, refrigerator consequently can not normally use if cleaning seldom just can produce very niff.
The principle one that the deodorant for refregerator sterilised products of market sale now adopts is to come the absorption harmful gas with active carbon material; The 2nd, use the electronics anionic sterilization, but existing product is and the uncorrelated stand-alone product of refrigerator control circuit, the working mechanism of employing is single, deodorizing sterilizing weak effect, efficient are low.
Summary of the invention
The technical problem that will solve of the present utility model is: the shortcoming at above prior art exists proposes the refrigerator electronic deodorizing sterilizing unit that a kind of deodorizing sterilizing is effective, efficient is high.
In order to solve above technical problem, the efficient refrigerator electronic deodorizing sterilizing unit that the utility model proposes comprises housing and is installed in the intravital active carbon filtration material of shell, its improvements are: also comprise mini fan, uviol lamp and nano photo-catalytic drainage screen, described housing is separated into and is respectively applied for the reative cell, filter chamber and the fan house that are communicated with successively that uviol lamp, active carbon filtration material and mini fan are installed, described reative cell and fan house are shaped on air-vent or grid respectively, and described nano photo-catalytic drainage screen is installed in the air-vent of reative cell or the inner surface of grid.
Be understood that, this utility model can adopt the gas with foreign flavor that contains pathogenic bacteria in the compulsory mode circular treatment cold compartment of refrigerator, its work process is that first being drawn in the reative cell by the nano photo-catalytic drainage screen of undressed gas sterilized, and then pass through the filter chamber, further remove residual pathogenic bacteria and abnormal flavour through filtration, absorption and the catalytic decomposition of active carbon material, after fan house to turn back to refrigerator cold-storage indoor.Obviously, because the processing procedure that this utility model adopts constantly circulation, twice sterilization to combine, so deodorizing sterilizing is effective, efficient is high.
Description of drawings
Below in conjunction with accompanying drawing this utility model is further described.
Fig. 1 is the structural representation of an embodiment of this utility model.
The specific embodiment
As shown in Figure 1, the efficient refrigerator electronic deodorizing sterilizing unit of present embodiment mainly is made up of housing 1, uviol lamp 2, active carbon filtration material 3 and mini fan 4.Housing 4 is divided into reative cell 1-1, the 1-2 of filter chamber and fan house 1-3 three interlayer chambers up and down, be respectively applied for uviol lamp 2, active carbon filtration material 3 and mini fan 4 are installed, the chamber is communicated with successively between above-mentioned three, and the both sides at reative cell 1-1 are shaped on fresh air inlet, and the bottom of fan house 1-3 is shaped on air exhausting grille.
Uviol lamp is installed in the central authorities of reative cell 1-1, is pasted with ultraviolet light reflective film material at the non-air inlet inner surface of reative cell 1-1, pastes the foam metal drainage screen of loaded with nano photocatalyst at reative cell 1-1 air inlet inner surface.Help like this reflexing to the photocatalyst filter net surface, improve the utilization rate of ultraviolet light, prevent that simultaneously reaction chamber wall is subjected to the irradiation under ultraviolet ray generating material aging shining its lip-deep ultraviolet light.Active carbon filtration material 3 is made into the Concha Arcae shape, and by two-layer nonwoven and contain efficient metal activity of such catalysts material with carbon element interlayer and form, its Concha Arcae is placed among the 1-2 of filter chamber in vertical direction; The air inlet of blower fan 4 links to each other with the air outlet of the 1-2 of filter chamber, and treated gas turns back to the cold room of refrigerator again from the air draft barrier of fan house 1-3 bottom.
Present embodiment also is provided with the power supply adaptor 5 of uviol lamp 2 special uses in addition, by it uviol lamp 2 is connected in the circuit of refrigerator, powered to blower fan by the circuit of refrigerator by the control of refrigerator pcb board.
During present embodiment work, under the effect of blower fan, gas in the cold compartment of refrigerator at first enters nanometer photo-catalytic sterilizing deodorization reative cell, this moment, uviol lamp was opened, nano photo-catalytic is activated, and kills the bacterial micro-organism that is included in the gas jointly by ultraviolet light and nano photo-catalytic, and gas with foreign flavor and ripener gas molecule are decomposed in simultaneous oxidation, form harmless gas molecule, as CO
2And H
2O etc.Its microcosmic mechanism of action is: on the irradiation under ultraviolet ray photocatalyst filter net and ultraviolet light reflecting layer of uviol lamp emission, the ultraviolet light that shines surface, ultraviolet light reflecting layer is reflected to the photocatalyst filter net surface again, guarantees that the ultraviolet light that uviol lamp is launched acts on the photocatalyst filter net to greatest extent.The ultraviolet light that shines the photocatalyst filter net surface is fully absorbed by the nano titanium oxide of its load, produces electronics and hole, and airborne oxygen contacts these electronics and hole and then forms hydroxyl radical free radical (OH) and negative oxygen base (O with moisture
2-), hydroxyl radical free radical (OH) and negative oxygen base (O
2-) have very strong oxidisability, harmful substances in air, under these strong oxidizer effects, oxidized soon and decompose as antibacterial, virus and gas with foreign flavor etc.The gas with foreign flavor or the ripener gas molecule that also can residually have small part not have oxidized branch to take off in the gas that handled process photocatalyst reaction chamber, after air-flow enters the filter chamber, residual in this section gas with foreign flavor or ripener gas molecule are very fast by the activated carbon adsorption of Concha Arcae filter, then under the effect of efficient metal catalyst by further oxidation Decomposition, form harmless gas molecule, the clean air that final process was handled is arranged in the cold room that turns back to refrigerator again by the air outlet grate of fan house.
Facts have proved, the efficient refrigerator electronic deodorizing sterilizing unit of present embodiment can be killed the antibacterial in the refrigerator effectively, expeditiously, the gas molecules that accelerate the ripening such as the gas of the abnormal flavour that the decomposition refrigerator contains and ethylene keep clean refrigerator, and strengthen the fresh keeping property of refrigerator.
In addition to the implementation, this utility model can also have other embodiments, and for example, this utility model can be equipped with independently power supply.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of this utility model requirement.
