Description

Indoor air cleaner

Affiliated technical field

The utility model relates to air cleaning unit, particularly a kind of indoor air cleaner.

Background technology

In the prior art, the indoor air purification product mainly contains two classes:

One class is the fiber filter technology: promptly use highdensity fleece to add a typhoon machine and carry out mechanical filter.This mode can be filtered sucked particulate bigger in the room air, flue gas.Because it is too little that the aperture of filter screen can not be accomplished, influences wind speed, flow and resistance, so the just filtering fully of the sucked particulate of small particle diameter and microorganisms such as bacterium, virus.On the contrary, gather floating dust and microorganism on the filter screen on the contrary easily, make it to become the hotbed that grows propagate microorganisms, easily produce secondary pollution, the resistance of air-flow strengthens, and gas pollutant then more can not filtering, and the use cost height.

Two classes are electro static filtering technology: promptly by electrion, with air ionization, make dusty gas pass through electric field, make pellet and flue gas force charged and condense upon on the laying dust plate.This mode is filtered has clean-up effect preferably to solid pollutant, and effects such as sterilization, poison are also arranged simultaneously, but because the electric field discharge constantly produces ozone, makes that ozone concentration constantly raises in the indoor air.Though ozone has the function of killing bacterium, poison, the ozone that concentration is high has very big harm to the people, and the Electrostatic Absorption technology is also inoperative to the purification of gas pollutant and peculiar smell simultaneously.

Said two products is commonly used for interior circularly purifying, when work, only (sinuous flow) in the effective circulated air around the clarifier played partial action, catharsis is little, and stuffy again ventilation, therefore, indoor because of human body respiration, smoking, cook, oxygen that the generation of finishing pollution, ozone etc. constantly consumes and poisonous, harmful waste gas of generation can not get replenishing and discharging, this is the deficiency of prior art just.

Summary of the invention

In order to solve the shortcoming that existing air purifier exists, the utility model provides the ventilation of a kind of energy, the indoor air cleaner that clean-up effect is good.

Above-mentioned task realizes by this way: this indoor air cleaner by blast pipe, prefiltering net, casing, electrostatic precipitator, carbon fiber adsorption and catalytic combustion net, anion generator form with air exhauster, blast pipe is connected with the air inlet of casing, prefiltering net is placed in the blast pipe, begin to set gradually electrostatic precipitator, NACF net and air exhauster from air inlet in casing, anion generator is placed in the inboard of casing exhaust outlet.

The technical solution of the utility model can also be done following further improvement:

In order to make the utility model both be applicable to the air cleaning of outdoor air intake, again applicable to the circularly purifying of room air, be provided with a threeway at the front end of blast pipe, two other connector of this threeway is connected with indoor blast pipe with outdoor blast pipe respectively.Logical valve in be provided with the distribution valve of a control room external air inlet pipe or indoor blast pipe air intake.This distribution valve can be manual can also being driven by small machine.

For ease of cleaning and change prefiltering net, it is to be provided with upper and lower guide groove at the blast pipe place that prefiltering net adopts the plug-in type concrete structure, and prefiltering net is placed in the framework, and this framework cooperates with the guide groove of blast pipe, be placed in the blast pipe, whole prefiltering net can slide along guide groove.

The utility model is to use like this: when needs replenish outdoor fresh air, blast pipe is communicated with or with blast pipe in the distribution valve close chamber of threeway, the blower fan that starts this clarifier then just can with outdoor.At this moment, outdoor fresh air is after particle that prefiltering net suspends in outside air and showy foreign material are isolated, allow cleaner air enter in the clarifier, pass through again after electrostatic precipitator and the further dust cleaning and sterilizing of carbon fiber adsorption and catalytic combustion net, sterilization and the absorption, air is basically by cleaning, evenly discharge cleanliness factor and the freshness that negative aeroion improves air through anion generator at last, make the air in the suction chamber be the cleaning ozone, stop effectively in the inlet chamber of outside contamination source, be good air ambient of indoor creation.Because new wind is in continuous input, increased air pressure for indoor environment space, make indoor air form windstream, windstream is towards the direction motion that air port or slit are arranged, under such state, by the pollutants that numerous pollution sources discharged such as human body respiration, smoking, finishing pollution can constantly discharge be outdoor by new wind, the pollutant levels in indoor environment space will keep minimum level forever like this.

If when meeting dust and sand weather and maybe need use air-conditioning, can allow clarifier be adjusted to interior recurrent state the distribution valve close chamber external air inlet pipe of threeway, can guarantee the purification of room air like this, cold, heating installation energy is scattered and disappeared.

In sum, the utility model is the interior airborne gas pollutant of decontamination chamber and VOC, peculiar smell and sterilizing timely and effectively, and the oxygen content that can make the room ventilation ventilation, replenish room air, therefore adopt the utility model can control indoor air quality and reach optimum state, this is that prior art is beyond one's reach.In addition, assembly of the present utility model have also that energy consumption is little, noise is low, the assembly mounting or dismounting with change very convenient and can supply the shared advantage of multi-chamber of family.
