Description

A kind of new blower fan

Technical field

The utility model belongs to ventilation equipment, is specifically related to a kind of new blower fan.

Background technology

In recent years, the room air pollution problem more and more causes people's attention, and the data at Chinese interior decoration association environment measuring center shows, China is annual to cause dead 11.1 ten thousand people that reach because of room air pollution.The modern city people worked and lives in the room about 18~20 hours of every day, the area that family and office decorate is big, furniture is put intensive relatively, various work life article are many, thereby pollution sources are many and complicated, problem is that this point is often not known, common people even to think indoor be to clean clean place most.Indoor air pollution is to cause one of major reason of various cancers, particularly lung cancer.

Family room's internal contamination mainly comes from the following aspects:

1. from the radioactive radon gas of radioactive element decay generation in the building materials, problem is more outstanding when especially making finishing material with stone material.

2. the formaldehyde of ornamental glued board and paint for decoration face volatilization and contain the phenyl ring organic matter, its unwanted volatile disengages and will last for several years even the longer time.

3. the people breathes the carbon dioxide of generation and the gas of human body volatilization, and smoking also is one of pollution sources in addition.

4. the pernicious gas that produces of food spoilage.

Solving the indoor pollution best bet is exactly ventilation, dilution and emission." heating and ventilation and air conditioning design specification " GB50019-2003 has clearly regulation to the central air-conditioning fresh air supply amount of various public places.For example: office, meeting room are 50m 2/ h, guest room 60~100m 2/ h.The office and the family room of considerable part are not all installed central air-conditioning and central VMC at present, and indoor and outdoor is ventilated and mainly circulated naturally by the door window air.But live in the city particularly the people of business district often be unwilling to open a window because outdoor dust, noise are big, indoor-outdoor air can not circulate naturally, enriching pollutants causes damage to human body.

The most frequently used forced ventilation method is that ventilating fan is installed in perforate on door and window or indoor wall now, use ventilating fan can discharge indoor contaminated air, but the air that the while external complement is come in also can be from door, dust is brought in the window slit into, because the perforate of ventilating fan installation site is bigger, generally there is not soundproof measures yet, in the easy inlet chamber of outdoor noise, the low frequency noise that adds ventilating fan itself all can be given the indoor noise pollution that causes, thereby the method all is reluctant to adopt by most of office and family, existing new wind devices is big, how need and lay airduct at indoor installation wind cabinet, takies stud, cost an arm and a leg, promote the use of and be restricted.

Summary of the invention

The purpose of this utility model is at above-mentioned situation, provides a kind of simple in structure, cheap, easy to install, allows the user solve the new blower fan of the ventilative problem of room ventilation under the situation of door window not.

Realize that the technical scheme that above-mentioned purpose adopts is: new blower fan mainly by casing, blower fan, filter screen and airduct, form, casing has air inlet and air outlet, has one in air inlet and the air outlet at least for can outer air duct or the interface in hole, blower fan is contained in the casing, air channel in the casing is provided with filter screen, and casing is provided with the installation hanger.

The further technical scheme of the utility model is: described filter screen can fixedly install, and also can movablely be provided with.Filter screen employing activity is provided with, and mounting groove can be set on casing, and filter screen is placed in the mounting groove, and mounting groove can adopt vertical setting as required, also can horizontally set, and the inserted mode of filter screen also is divided into plug-in type or side direction plug-in type up and down.The benefit of movable filter screen is to be convenient to clean and change.The material of filter screen can adopt textile cloth, composite or ventilative paper to make.The installation site of filter screen in casing both can be positioned at the front of blower fan, also can be in the back of blower fan.

The another kind of technical scheme of the utility model is: the ripple airduct is housed on air inlet or the air outlet.After this machine is equipped with airduct, can outdoor or indoor air be introduced by airduct, its installation site is more flexible, and convenient for cleaning, maintenance is particularly suitable for outdoor installation.

Another technical scheme of the utility model is: described casing front portion is provided with rain cover, is used for body and is installed in and prevents rainwater when outdoor.

Another technical scheme of the utility model is: on the air channel of this machine negative oxygen ion generator is set, be used for the purification of air and increase negative oxygen ion concentration, negative oxygen ion generator can be arranged on the front end on the air channel of this machine, also can be arranged on terminal or middle on the air channel.

Installation of the present utility model and use: the user can select this machine is installed in outdoor or indoor according to different situations, just can realize to indoor air-supply as long as adjust traffic direction.On the wall or the hole of opening a suitable airduct on the window, connect blower fan and indoor (outward) during installation with pipeline.

Main feature of the present utility model is to adopt unit to utilize on the building smaller aperture due to carry out room ventilation, make outdoor air through filter screen by blower fan work, send into indoor behind the elimination dust, make indoor formation malleation, room air can be discharged by the exhaust outlet of door, window slit and kitchen, toilet, can also prevent that outdoor dust from entering from the door and window slit in the circulation of air under realizing not the door window situation.Because be that unit can utilize smaller aperture due ventilation on the building, and available airduct junction chamber interior (outward) and blower fan, avoid in the outdoor noise inlet chamber.It is relatively simple for structure, and is cheap, and easily installation and maintenance, and less demanding to building when installing can only need be made a call to an aperture and be got final product in any position, be specially adapted to high-rise building resident family.This machine greatly reduces operating noise owing to can use low noise blower fan and blower fan to be installed in the casing, and main frame is installed in when outdoor especially true.This machine is installed the larger area filter screen, makes the flow velocity of air on the unit are filter screen be controlled at 5~10% of air port flow velocity, can use fine and close filter screen, makes airfiltering quality guaranteed.

Further specify the technical solution of the utility model below in conjunction with accompanying drawing.
