Description
Technical field
The utility model relates to a kind of compound ventilation air-changing device, is applicable to that specifically confined space can realize continuing the ventilation fan of ventilation.
Background technique
People are for the comfortable air conditioner of having invented, and the birth defect of air conditioner is must be in its high workload usefulness of airtight indoor competence exertion, just because of this birth defect, cause indoor air but in time to be replaced and be subjected to severe contamination because of long-time use, pollution sources have flue gas, second-hand-cigarette, bacterium, virus, carbon dioxide (human body exhalation), nitride (dye for fabrics disengages), aldehyde and compound harmful matters such as (paint disengage) thereof, are having a strong impact on the health the people of indoor activities, work, rest, sleep.Under existing conditions, drain the vitiated air method has four kinds: the first, open door and window, and allow indoor air circulate, drive vitiated air away, make indoor air pure and fresh, but reduce the effect of air conditioner widely; The second, discharge fan is installed, vitiated air is drained, but, still fail to reach the purpose of anticipation, moreover the ventilating fan that turns round in confined chamber is because the effect of back pressure makes a noise in blade place turbulization owing to lack replenishing of fresh air; The 3rd, intermittently interactive ventilation fan is installed, when reversing, blade sends into fresh air, mix with vitiated air, behind the certain hour, blade just changes, and discharges mixing air, so moves in circles; The 4th, two ventilating fans are installed, one inwardly air-supply, and another outside exhaust makes indoor air form circulation, constantly replaces, and keeps indoor air fresh.Based on the using effect that guarantees air conditioner in the space, method one can not adopt because of the effectiveness of having offset air conditioner, and method two, three effects are not obvious, and the method having ideals, morality, culture, and discipline is than obvious effects, but uses equipment many, and cost height, power consumption are big.
Summary of the invention
The purpose of this utility model is to overcome the above deficiency of prior art, and provide a kind of and can realize two-way row's ventilation, and ventilation fan simple and reasonable, easy to use, that cost is low, power consumption is few.
Provide a kind of health environment-friendly ventilation fan according to above-mentioned purpose, comprise face shield, back top box, bellows, impeller, motor, impeller is installed in the rotating shaft of motor, and described impeller is provided with coaxial inside and outside two groups of flabellums, interior flabellum is positioned at the center of impeller, and outer flabellum then is positioned at the circumference outer of impeller; Also has the isolation ring flat-plate on the impeller, this isolation ring flat-plate is divided into separate interior wind chamber and exogenous wind chamber with the bellows inner chamber, interior flabellum is positioned at the wind chamber, and outer flabellum is positioned at the exogenous wind chamber, and the bellows surface then is provided with and is used to be communicated with exogenous wind chamber and the intake opening of the exterior space and the exhaust vent that is used to be communicated with the exogenous wind chamber and the interior space.
Be provided with isolating cylinder in the top box of described back, this isolating cylinder is divided into separate air intake passage and ventilation channel with the bonnet box cavity; Air intake passage is communicated with the exogenous wind chamber by intake opening, and ventilation channel is communicated with interior wind chamber through interior flabellum; Support of motor is installed on the isolating cylinder.
The structural type of described inside and outside two groups of flabellums can make up as required, is the axial flow flabellum as interior flabellum, and outer flabellum is centrifugal flabellum; Also can be that interior flabellum is centrifugal flabellum, outer flabellum be the axial flow flabellum; Can also be that inside and outside flabellum is the axial flow flabellum or is centrifugal flabellum.
As further improvement, in exogenous wind chamber or the air intake passage electro-heat equipment can be set, can adopt PCT heater element, electric heating wire or other heater elements that is fit to here; In addition negative ion generating device can also be set, to satisfy more multi-layered inferior demand.
Because a duplexing impeller with coaxial two group disjunctor flabellums is installed on a motor, has the isolation ring flat-plate that the bellows inner chamber is divided into separate interior wind chamber and exogenous wind chamber on this impeller, have in the back top box bonnet box cavity is divided into the separate air intake passage and the isolating cylinder of ventilation channel, so just in a ventilation fan, form two air-flow paths of isolating mutually.Thereby can realize finishing simultaneously the function that inhales fresh air and discharge vitiated air.Compared with prior art, its beneficial effect is:
1) indoor vitiated air is continuously replaced from the outdoor fresh air of sending into, even make the air in the confined space still continue to keep fresh, with the cleaning of people that offers in indoor activities, work, rest, sleep, wholesome air ambient.
2) under the present case, finish said process, must dispose two ventilating fans, finish toward in for one and send, finish toward effluxing, so expended more electric energy for one---two motor electricity consumptions, consumed more material---more plastics, more steel, more copper cash, and ventilation fan of the present utility model is unit work, and power consumption, feed consumption are all than saving.
