Description
Technical field
Field of air purification device is the utility model is related to, is handed over more particularly, to the binary channels air with total-heat exchanger
The clarifier of purification is changed, is a kind of Integral air clearing machine specifically.
Background technology
Air quality has been that country or even world's environmental sanitation tissue consider a country, area or city environmental pollution
One of important indicator.With the continuous quickening of process of industrialization, as people in the countryside are constantly to urban migration, premises are promoted
What production was built accelerates, meanwhile, in order to tackle growing traffic pressure, the quantities for urban road construction is also
It is doubled and redoubled, motor vehicle exhaust emission is also increasing；Any of the above factors cause to have a strong impact on to air quality invariably.For
The quality of life of people is improved, air cleaning degree is improved, typically by the way of later purification to living or working
The air in region carries out purified treatment.At present, can generally be summarized as taking a breath for improving the mode of air in buildings quality
Two kinds of processing and purified treatment.So-called ventilation processing is that will have poisonous and hazardous air in building, such as due to fitting up material
Expect formaldehydes toxic and harmful gas of release etc., excluded room air using ventilation fan or ventilating fan, by outdoor air
Suction, air exchange is carried out, reach the purpose of ventilation.The advantages of this processing mode, is that processing cost is very low, deficiency
Be in it is big in noise, its air quality height place one's entire reliance upon outdoor air quality, can not fundamentally solve control matter
Amount problem, it is impossible to realize clean-up effect.So-called purified treatment is to carry out the air of interior by way of physics or chemistry
Effectively purification, the harmful substance in air or gas is got rid of, to realize the purpose of purification of air, this mode purifies effect
Fruit is good, but cost is also higher；But the simple purification dependent on air, its efficiency is very low, especially in larger sky
In, house or office building soon is such as just fitted up, its purification cycle is very long, it is impossible to meet the need such as office in time
Ask.
Prior art 1：Chinese invention patent application, Application No. 201510404798.0, application publication number CN
105371377 A provide air purifier, can also be readily seen that display part even if from the position away from air purifier, and hold
Easily carry out the wet wipe on input unit periphery.The present invention is a kind of air purifier (100), is possessed：The air of importing is entered
The main part (11) that row is purified and discharged；And the front glass panel (16) before the main part (11), on
State air purifier to be characterised by, the above-mentioned front glass panel (16) with touch switch device (28) is operation air
The touch panel of clarifier (100), in above-mentioned front glass panel (16), show the defeated of above-mentioned air purifier (100)
The display part (18) for going out information is formed on the top of the front glass panel (16).
Prior art 2：Chinese invention patent application, Application No. 201610862845.0, application publication number CN
106422553 A disclose a kind of air purifier, including air purifier body, excessively top air admission hole, air filtering aperture, mistake
Plate, air outlet pipe and air exhauster are filtered, top air admission hole is set on air purifier body top plate, and filtering plate is arranged on air
In clarifier body, filter and be provided with air filtering aperture on plate, air outlet pipe is arranged on air purifier body right plate
Bottom, on air exhauster is arranged in air purifier body bottom plate, the bottom of the air purifier body is equipped with wheel.It is above-mentioned
Air purifier sets air exhauster, profit by setting air admission hole at air purifier top plate position on air purifier bottom plate
The air exhauster with bottom plate is influenceed with gravity, accelerates purification of air speed, there is the characteristics of easy to operate, purification air velocity is fast.
The program is similar to be with purified treatment mode affiliated in background technology, treatment effeciency of this processing mode in larger space
Very low, the effect after simply purifying can be better than ventilation processing mode, when in the noxious air environment in high concentration, this
Kind processor is difficult to play actual effect.
