The combined type ventilation fan

Technical field

The utility model relates to a kind of device for exhausting oily smoke, especially a kind of combined type ventilation fan with ventilation, air purification processing capacity.

Background technique

Range hood has become the main selection of newly purchasing dwelling house family at present, but because the ventilation efficiency of range hood is relatively low, can not get rid of the oil smoke that gathers fully during use, using effect is not very good, uses so present most of family is still basically based on ventilation fan and two kinds of product assortments of range hood.The ventilation fan product of market sale is because structural limitations cleans very difficulty after greasy dirt adheres to; Also occurred some special-purpose smoke pumping ventilation fans on the market, but their cleaning and use operation are still inconvenient, do not tackle the problem at its root.

Summary of the invention

In order to overcome the deficiency that existing smoke pumping ventilation fan cleaned and used inconvenient operation, the utility model provides a kind of novel combined type ventilation fan with ventilation, air purification processing capacity, this combined type ventilation fan can not only high efficiencyly be finished ventilation and fume exhausting function, and be convenient to clean cleaning, use easy to operate.

The technological scheme that its technical problem that solves the utility model adopts is, design a kind of combined type ventilation fan, which comprises at least ventilation fan body, motor, fan blade, ON-OFF control circuit, it is characterized in that: filter screen 14 is arranged on the panel of ventilation fan body, and filter screen 14 aperture maximum diagonal length are chosen in 3-6mm.

Be connected with air duct 5 between the front cover 15 of described ventilation fan body and the bonnet 7, air duct 5 cavitys have tapering, and air duct 5 apertures that are connected with front cover 15 are greater than air duct 5 apertures that are connected with bonnet 7.

Be socketed with rainproof fan housing 16 outside the housing 6 of described ventilation fan body.

The front cover 15 of described ventilation fan body links to each other with housing 6, and the fan blade 3 that motor 1 and motor shaft end connect is fixed on the housing 6 by electric machine support 13, and fan blade fixed cover 2 is connected fan blade 3 front ends, and oil box 10 is fixed on ventilation fan body front cover 15 bottoms; On front cover 15 front-end faces, be connected with filter screen 14; The front cover 15 central circular cavity peripheries convex edge that extended back is connected with bonnet 7 on housing 6 ear end faces, and the center circle periphery of bonnet 7 is extended with the card rib forward, is connected with air duct 5 between the card rib of the convex edge of front cover 15 and bonnet 7; On front cover 15 ear end faces and housing 6, be socketed with rainproof fan housing 16.

Described rainproof fan housing 16 is cavity structures, its front port is that square and ear end face shape same size body front cover 15 match to merge and be fixed together, the rainproof fan housing 16 ear end face first halves are the arc covers with the body integrative-structure, are that ventilated port and air port are downward below the Lower Half substantially horizontal.

Described filter screen 14 is wire nettings.

Described filter screen 14 mesh are squares, are positive prismatic and distribute, and the cornerwise length of filter screen is chosen in 4-5mm.

Working principle of the present utility model is: after connecting electrical convertors and generators 1 and fan blade 3 work, hot gas and oil smoke that domestic furnace or kitchen range produce can be drawn in the cavity of air draft mechanism, and discharge by bonnet and rainproof fan housing 7 fast, oil smoke wherein is through the filtration first of filter screen 14, the gathering of conical air duct 5, the tobacco tar that produces flows in the oil box 10 smoothly, thereby finishes the function of ventilation and air purification processing.

Characteristics of the present utility model are: the standard on standard piece such as boundary dimension of the present utility model, motor, fan blade and the market and measure-alike, different is that this device has adopted filter screen at the front-end face of ventilation fan body, filter screen 14 apertures are 3mm, its characteristics are to assemble tobacco tar, the greasy dirt of considerable part is attached on the filtering net surface, make it to flow into smoothly in the oil box, be convenient to cleaning, play the tobacco tar effect of filtering; Filter screen need not clean, and filter screen adopts metallic material, and it is promptly reusable that the oil smoke that adheres to allows it fully burn on fire; Also played anti-mosquitos and flies in addition, the effect of filtration fraction dust.Be connected with air duct 5 between the front cover 15 of ventilation fan body and the bonnet 7, air duct 5 cavitys have tapering, and air duct 5 apertures that are connected with front cover 15 are 28cm, and air duct 5 apertures that are connected with bonnet 7 are 25cm, make behind the air duct lowly before high, the oil smoke in the air duct flows in the oil box of ventilation fan front end along tapering.Rainproof fan housing is the arc fan housing, and Open Side Down, and oil smoke flows out along the arc fan housing; It can produce stronger blast, makes farther that vitiated air blows, also can natural ventilation under the situation of not starting shooting.The utility model has the smoke pumping complex function of efficiently taking a breath easily because air draft mechanism adopts the blade type large aperture, compares single ventilation fan or single smoke pumping has good cost performance, and power is little, exhaust air rate is big, practical, easy to use.
