Abstract

The utility model relates to an air filtering ventilator capable of filtering and purifying outdoor air and then sending the air indoors, which is matched with the existing double-layer hollow glass window with better noise reduction performance to form a solution to overcome the puzzle that the urban traffic, the architecture and the environmental noise interferes to living rooms. Valid noise reduction is completed by closing the door and the window. To solve the problem of non-circulation of indoor air, the air filtering ventilator filters and purifies the outdoor air and then sends the air indoors to complete indoor air exchange. Because air input is adjustable, the ventilator is also suitable for air exchange in air-conditioning rooms or rooms requiring clean air. The ventilator forms a cylindrical shape, and an outer shell is made of PVC plastics which have the advantages of rainproof, sunproof and aging resistant performance. The ventilator is installed on the outdoor wall, and the switch is controlled indoors. The working condition is that because the draught fan composed of the electric machine and fan blades rotates rapidly, outdoor air flows through a rough filtration screen to filter off larger suspended matters in air including mosquitoes and flies. Formed airflow goes through the air filtering core to filter off the dust and enters the room from an air outlet through a connected corrugated pipe and a wall plastic pipe to make the people have no troubles of noises, mosquitoes and dust when breathing the fresh and cleaning air.

Description

The air filtration ventilation blower

Technical field: the utility model relates to civilian room ventilation ventilation blower fan field.Be primarily aimed at the room for after reducing the environmental noise harassing and wrecking and closing the doors and windows, solve the indoor air-changing problem and ventilation blower new varieties designing.Its function is undisturbedly fresh after filtering to indoor conveying, dustless, cleaning, and the adjustable outdoor air of air inflow.

Background technology: at present, urban traffic noise and environmental noise are puzzlement citizen study, especially one of night's rest big public hazards, noise-reduction method is that the double layer glass window is installed preferably at present, under the situation that door and window is closed, can reduce noise effectively to indoor interference.But this has also blocked the convection current and the circulation of room air and outdoor air, and the time one is long, and room air is inevitable dirty.Noise reduction and indoor air-changing can not be satisfactory to both parties.Existing ventilation fan on the market, the overwhelming majority are to adopt pump drainage to outdoor mode, since its installation site, the body noise, airflow direction, causes such as air channel inconvenience cleaning, its attribute has determined and can not play a role under this specific situation.

Summary of the invention: the use that matches with the double layer glass window of the utility model air filtration ventilation blower, form a total solution of falling end noise jamming and indoor air-changing.Effectively noise reduction is finished by closing the doors and windows, and the room air that causes does not circulate, and is sent into after with the outdoor air filtration, purification indoorly by the air filtration ventilation blower, finishes indoor air-changing.The technical scheme that its technical problem that solves the utility model adopts is: for make noise reduction with the ventilation both take into account, ventilation blower is made as outdoor installation, (avoiding the body noise) airflow direction from outdoor to indoor force feed.Finish by the blower fan that motor and fan blade are formed.The ventilation blower air inlet is settled the stainless steel sift screen cloth, and airborne big suspension is fallen in coarse filtration, comprises mosquitos and flies.Settle air filtering core in the air channel, filter out most dusts in the air, air is purified, and play and reduce blower fan and the effect of outdoor noise in the inlet chamber of air channel.Utilize the siphonage of air-out air-flow, a tubulose air filtering element (cartridge) is set, room air is play a part to refilter indoor air outlet tube mouth STH.Establish the circuit for reversing switch in the blower fan circuit, it is reverse to be convenient to air-flow, automated cleaning air filtering element (cartridge) and coarse filtration screen cloth, if speed-regulating switch is to adapt to the needs of indoor different situations, owing to be outdoor installation, shell adopts the PVC plastics with rainproof, and is sun-proof, anti-aging, concrete installation site should be left outside window, the right side, downside, the place that indoor staff can reach is so that cleaning or replacing air filtering core.The beneficial effects of the utility model are:

1. the noise reduction of closing the doors and windows, during ventilation blower work, room atmosphere is pressed and is higher than outdoorly, and oxygen content increases in the air, and dust reduces, and dust can't be beneficial to health in slit inlet chambers such as door and window.

2. stop in the outdoor mosquitos and flies inlet chamber, because the effect of empty filter core has reduced house dust greatly.

3. because indoor air outlet siphon refilters the setting of device, room air can be refiltered.Select for use corresponding catalyst to place the air outlet box, can also remove foreign flavor indoors, make with fresh air.(as air freshener, perfume, etc.)

4. because intake is adjustable, can be used as air-conditioned room and continue air interchanger.

5. close the doors and windows away from noise, dust, mosquitos and flies puzzlement, the quiet sleep of having a breath of fresh air are beneficial to health.
