Description

A kind of return air inlet for air-conditioner air cleaning unit

Technical field

The utility model relates to field of air purification device, especially return air inlet for air-conditioner air cleaning unit.

Background technique

Room air pollution is serious in recent years, and especially new house space is small, art work and new furniture pollutant burst size Greatly, general that room air pollution is solved by draft type.And single layer strainer mesh is straight in existing conditioner cover board Diameter reaches 1-2mm, only coarse filtration function, and cover board single-layer filter is usually plastic cement material, and the air passed through with return air inlet rubs Wipe easy to produce static electricity, adhering dust easily adsorbs dust, breeds bacterium.

Thus, how to provide it is a kind of be not only able to achieve air-conditioning return air function, but also be able to achieve except formaldehyde, deodorization, anti-pollution function, And be not easy to adsorb dust, the air cleaning unit for breeding bacterium becomes industry technical problem urgently to be resolved.

Utility model content

The applicant is directed to above-mentioned existing issue, has carried out Improvement, provides and be not only able to achieve air-conditioning return air function, but also energy It realizes the function of removing formaldehyde, deodorization, anti-pollution, and is not easy to adsorb dust, breed the return air inlet for air-conditioner air cleaning unit of bacterium.

Technical solution used by the utility model is as follows：

A kind of return air inlet for air-conditioner air cleaning unit, including framework and the strainer being placed in inside the framework, at least There are two the strainer, the strainer is equipped with the coat of photochemical catalyst, is equipped with light source between the strainer.Coat is by receiving The photochemical catalysts such as rice titanium dioxide spray to be formed.

In above scheme, including three strainers, the strainer include the first strainer of blinds in the neighbouring framework, And the second strainer and third strainer are arranged successively after first strainer, the light source is located at second strainer and institute It states between third strainer.

In above scheme, first strainer is metal mesh, and second strainer is corrugated filter net, the third strainer For activated charcoal strainer.Organ filter paper (corrugated filter net) can be used in second strainer.In above scheme, first strainer and institute Stating third strainer is honeycomb strainer.First strainer is effectively prevented from the windage passed through with return air inlet for metal mesh and is also easy to produce Electrostatic, coat have antistatic, and super hydrophilic function is easy to clean.

In above scheme, the strainer is fixed on the frame by fixed structure.Fixed structure can be magic tape, card The modes such as button, but not limited to this.

In above scheme, the light source is ultraviolet radiator.Pass through the second strainer (corrugated filter net) and third strainer (activity Charcoal filter screen) ultraviolet radiator irradiation built in centre, can filter tiny particles content and be catalyzed, interior volatility of degrade it is organic Object, disinfection and sterilization reduce air pollutants and injure to human health.

In above scheme, coat is coated on the substrate surface of strainer.First strainer can be contacted outer by the blinds of frame The light source in portion, the second strainer (corrugated filter net) and third strainer (activated charcoal strainer) pass through ultraviolet radiator between Irradiation, for coat under the action of the ultraviolet light of light source, exciting light catalyst decomposes various organic matters and bacterium, virus While can also be carried out disinfection by the irradiation of interior UV lamp sterilization.

Ultraviolet radiator can be connect with air-conditioning switch power supply, can produce purification air while opening air-conditioning, disinfection is killed The effect of bacterium, it is simple and convenient.Air-conditioning draught fan usually need to be only opened, does not implement air conditioner refrigerating or heating mode even, it can also Air purification is played, the function of general air purifier can be replaced.I.e. air-conditioning takes any operating mode, and sky can be achieved Gas purification, disinfection and sterilization effect.

In above scheme, activated charcoal strainer can be used aluminum honeycomb, plastic honeycomb, paper honeycomb frame of through-hole structure etc. and be Carrier.Active carbon can be particulate filler in carrier honeycomb gap, be also possible to powdered, be attached to entire poly- ammonia In ester foam screen frame.Alveolate activated carbon strainer carries attached cocoanut active charcoal and is made, and phosphorus content has and lives 50% or more The property efficient absorption property of charcoal, in adsorbable removal volatile organic compounds formaldehyde, toluene, hydrogen sulfide, chlorobenzene and air Pollutant.Activated carbon surface is coated with photochemical catalyst, decomposes containing toluene, dimethylbenzene, benzene etc. by ultraviolet light irradiation is adsorbable The organic gas such as benzene class, phenols, esters, alcohols, aldehydes and foul gas.Compared with conventional carbon filter screen, have more excellent Good aerodynamics performance, bulk density is small, and large specific surface area, adsorption efficiency are high, and air resistance coefficient is small.Low energy consumption, certain wind It measures lower deodorization, eliminate the unusual smell, environment purification has good clean-up effect.

The beneficial effects of the utility model are as follows：

1. the utility model is equipped with built-in ultraviolet radiator, it is coated with photochemical catalyst on three layers of strainer, by internal purple The irradiation of outside line lamp can also excite photochemical catalyst, can generate ultra-oxygen anion free radical (O2), association negative oxygen ion, not only It can also fresh air with disinfection and sterilization；Various organic matters and bacterium, virus can also be catalytically decomposed simultaneously；While opening air-conditioning It can produce the effect of purification air, disinfection and sterilization, it is simple and convenient.

2. the return air velar plate of the utility model compared with prior art, first strainer of the utility model is metal material, It is not likely to produce electrostatic, and coat has the function of antistatic, super hydrophilic, it is easy to clean.

3. the strainer purification efficiency coated with photochemical catalyst of the utility model will not failure, ultraviolet radiator energy consumption is small, effect Fruit is effective for a long time.Alveolate activated carbon strainer absorption property is high, the organic matter of absorption and bacterium etc. can be killed by photochemical catalyst, It decomposes.After having used the utility model, the alternative air purifier of air-conditioning, to realize multi-purpose machine.

4. the utility model low voltage and low power ultraviolet radiator limits irradiation area, not will lead to air conditioning units aging.

5. effectively reducing dust after the utility model filters dust by the present apparatus and entering air-conditioning internal machine heat exchanger, extend Machine service life.
