Description
Technical field
The utility model relates to a kind of pure and fresh ventilator that is used to improve family's IAQ.
Background technology
Family's air quality and health condition of people are closely related, and the main method of improving IAQ at present is the ventilation of windowing, and this also is the item that doctor and the frequent reminds people of all kinds of medical book are noted.Yet along with the aggravation of environmental pollution, the outdoor air quality particularly the northern China urban air-quality worse and worse, door and window one is opened, air is being mingled with various dust and pernicious gas and is pouring in indoorly together, not needing for a long time, ground and furniture, bed promptly are one deck dusts.Ventilation also can be subjected to the noise harassing and wrecking to influence sleep if window at night.And the house decoration class is generally higher now, so people are often for avoiding the indoor ash door window less of trying one's best that advances, and this will inevitably make IAQ be subjected to very big influence.This problem has been that of generally feeling in present people's daily life does not include little worry.
At present, the product that improves family's IAQ mainly contains two kinds: the one, and air cleaner is installed in indoorly, mainly is made of motor, wind wheel, filter course, will discharge behind the air intake filter, through repeatedly circulating air cleaning.Its shortcoming is that cost is higher, and does not have the indoor-outdoor air exchange, can only play partial action, and the ventilation that can not replace fully windowing also can be subjected to the influence of NF.The 2nd, ventilation fan (generally being that suction is two-way), simple in structure, constitute by motor, wind wheel etc., by the suction and discharge forced ventilation, to improve air quality, its shortcoming is not have filter, and the outdoor air entrained dirt is together in the inlet chamber in the scavenging period, more because noise aspect former thereby can only be installed in toilet and kitchen etc. and locate can not solve air quality and dirt problems fully.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure and indoor pure and fresh ventilator of family that does not have influence of noise.
For achieving the above object, the utility model adopts following technical scheme: the pure and fresh ventilator of a kind of family, comprise blower fan, and described fan outlet is connected with airduct, and the wind tube outlet position is provided with screen pack.
In order to reduce wind resistance, described wind tube outlet place is provided with outlet housing, and described screen pack is inlaid in the outlet housing mouth.
Adopt technical scheme described in the utility model, blower fan is installed on the outdoor wall, and it is indoor that air outlet connects the airduct feeding, and the noise when blower fan is worked like this is to indoor basic not influence, wind tube outlet position installing screen pack, the dust filtering that outdoor air can be carried secretly.The utility model is simple in structure, cost is low, and the wind tube outlet place is provided with outlet housing and is installed in indoorly, and screen pack is inlaid in the outlet housing mouth, and cleaning maintenance is very convenient.
Description of drawings
Accompanying drawing is depicted as the utility model mounting structure schematic diagram.
The specific embodiment
As shown in the figure, the blower fan 7 of the pure and fresh ventilator of this family is fixed on the outside of room wall 4 by installing rack 8, the air outlet of blower fan 7 is connected with airduct 6, be equipped with circular hole 5 on the wall 4, airduct 6 penetrate circular hole 5 and be installed in indoor outlet housing 1 and be connected, outlet housing 1 is fixed on the inboard of room wall 4 by installing rack 3, and inside, air outlet place is embedded with a screen pack 2.The area of screen pack 2 that is positioned at outlet housing 1 air outlet plays the reduction windage much larger than the sectional area of airduct 6, reduces blower fan 7 load effects.
Blower fan 7 of the present utility model is installed in outdoor, and the installation site makes the indoor influence that can not be subjected to blower fan 7 work noises away from the circular hole on the wall 45 simultaneously, helps reducing cost, and is easy for installation.Screen pack 2 is positioned at indoor, can adopt metal, nonwoven, composite to make, and is convenient cleaned and changed.More because designs simplification, help beautifying design, it is indoor attractive in appearance that whole device is not influenced.
