Abstract

The utility model belongs to the technical field of air filtration, in particular relates to an protective filtering cover of an air inlet opening of an all-fresh-air air conditioner, which solves the problems of the prior project air conditioning that the replacement of the beginning efficiency filter and middle efficiency filter is frequent and a great amount of materials are wasted, and the operational cost of the air conditioning is increased. The utility model comprises a cover body fixed with the air inlet opening, a rain curtain attached on a framework is arranged at the most external end of the air inlet opening of the cover body, a moth proof mesh and a dust proof cloth attached on the framework are respectively arranged in sequence from an air inlet end to an air outlet end inside the cover body at intervals, one side of the framework is respectively hinged on the inner wall of the cover body, the circumference of the dust proof cloth is fixed on a metal mesh through tape supported adhesive, and the metal mesh is fixed with the framework. The utility model can efficiently reduce the entering of foreign objects such as dust, moth, etc., the beginning efficiency filter and middle efficiency filter inside the air conditioning casing are protected, the replacing frequency is decreased, the operating cost of the air conditioning is reduced, the indoor air quality can be effectively ensured for a long term, and the assembly, the disassembly, the cleaning, or the replacement is convenient. The utility model can be reutilized repeatedly, the cost is low, and the market prospect is good.

Description

Whole fresh wind air-condition air inlet protection filter mantle

Technical field

The utility model relates to the air filtration technical field, is specially a kind of whole fresh wind air-condition air inlet protection filter mantle.

Background technology

At present, the place of IAQ being had relatively high expectations at Animal Lab. etc. mostly is equipped with the engineering air-conditioning, at the beginning of the pressure fan of engineering air-conditioning is fixed with, in, high efficiency particulate air filter, to collect dust, reach the effect of air cleaning, after air-conditioning unit operation a period of time, be air quality and the ventilation volume after the assurance filtration, usually at the beginning of needing to change, medium effeciency filter, or even high efficiency particulate air filter, but in the existing air-conditioning unit at the beginning of, in, high efficiency particulate air filter all is installed in the unit usually, is a machine made device, wherein roughing efficiency air filter can be changed, unpick and wash, but operate more loaded down with trivial details, and in, high efficiency particulate air filter can't clean, and can only change, this has just wasted great amount of manpower and material, causes the operation of air conditioner cost to improve greatly.Especially in the north, dust storm is big, and clogging often appears in first, medium effeciency filter, particularly purifies the zone at brand-new wind, and replacing first, medium effeciency filter is frequent especially, and the expense of Chan Shenging is also expensive unusually therefrom.With a resh air requirement is 10000M ³The air conditioner batch total calculate, be used to every year change just, the cost of medium effeciency filter just surpassed more than 100,000 yuan, if change untimelyly, then can directly damage high efficiency particulate air filter, even cause indoor air not up to standard, thereby result in greater loss.

Summary of the invention

The utility model is changed frequent for first, the medium effeciency filter that solve existing engineering air-conditioning and has been wasted lot of materials, causes problems such as operation of air conditioner cost raising, and a kind of whole fresh wind air-condition air inlet protection filter mantle is provided.

The utility model is to adopt following technical scheme to realize: whole fresh wind air-condition air inlet protection filter mantle, comprise and the fixing cover body of air inlet, the outermost end of cover body air inlet is provided with the curtain of rain that is attached on the framework, by air intake to outlet air end compartment of terrain successively fly net, the dustcloth that is attached to respectively on the framework is set in the cover body.The curtain of rain described in the utility model can prevent that rainwater from flowing into, and fly net is used to prevent that winged insect etc. from entering, but the dustcloth blocks dust, and ecto-entad forms the three-layer protection net.During use; only need the outlet air end of cover body is connected with engineering air-conditioning air inlet; be equivalent to filter device at the beginning of air-conditioning air inlet place has installed additional; can effectively reduce entering of foreign material such as dust, winged insect, protect first, medium effeciency filter in the Air conditioner box, reduce it and change number of times; reduce the operating cost of air-conditioning; and the utility model is convenient to dismounting, cleaning, replacing, can repeated multiple times use, and cost is very low.

For the ease of changing or clean the curtain of rain, fly net and dustcloth, described framework one side is articulated in the cover body inwall respectively, make framework freely to open, be convenient to dismounting simultaneously, spacing distance between each framework can be opened and be independent of each other with adjacent frame and be as the criterion, the articulated manner of described framework and cover body inwall can adopt various ways, and such as hinge-type, rotary shaft, this is that those of ordinary skill in the art is easy to realize.

Because the dustcloth material is softer, the airflow of avoiding producing when air intake damages it, is fixed on the wire netting by adhesive tape around the described dustcloth, and wire netting can play the effect of supporting dustcloth, wire netting and frame fixation, described dustcloth is to be made by nonwoven.

Described fly net is to be made by one deck gauze at least, and the gauze number of plies is many more, and vermins-proof effect is good more, but may influence intake, so in actual use, can determine the quantity of gauze according to demand.

Compared with prior art; the utility model adopts the protection filter mantle of establishing the curtain of rain, fly net and dustcloth in engineering air-conditioning air inlet place installs additional; can effectively reduce entering of foreign material such as dust, winged insect; first, medium effeciency filter in the Air conditioner box have been protected; reduce it and change number of times; reduce the operating cost of air-conditioning; simultaneously can guarantee indoor air quality long-term effectively; and the utility model is convenient to dismounting, cleaning, replacing; can repeated multiple times use; cost is lower, has good market prospects.
