Abstract
The utility model relates to an energy-saving scavenger fan used for improving indoor air environment. The utility model is characterized in that the utility model also comprises a blowing fan and an air box which is composed of an upper and a lower cover plates, a middle baffle plate and two sets of spiral double air channels except an exhaust fan. The air box is divided into an inner air zone and an outer air zone by the middle baffle plate. A set of double-air channel is arranged in the two air zones respectively, and the double-air channels arranged in the inner and the outer air zones are communicated mutually in a spiral center. The exhaust fan and the blowing fan are respectively arranged on the air outlet and the air inlet of the double-air channel positioned in the outer air zone. The utility model not only can achieve the purpose of exchanging air in rooms, but also can prolong the life time of air conditioners and save energy.
Description
The utility model relates to ventilation installation, belongs to a kind of in order to improve the discharge fan of indoor air environment.
Existing in order to improve the discharge fan of room air, consist predominantly of the fan blade and the motor that are fixedly mounted in the housing in its structure.The driven by motor blade rotates and exhausting.Along with improving constantly of people's living standard, people more and more are particular about the comfortable of living environment, so it is also more and more that other of domestic air conditioner be installed.The room of device must keep semi-closed state owing to install an air-conditioner, so it is generally all quite muddy that its room air of room of air-conditioner is housed, oxygen lacks, and is unhealthful.For improving room air, can only the window ventilation or adorn a simple exhaust fan and solve of somebody family.These two kinds of methods all will influence room temperature, and discharge fan can only exhaust, and outdoor fresh air can't replenish by it, also simple exhaust certainly will make the air-conditioner overtime again, both shortened the life-span of air-conditioner, waste energy again.
The purpose of this utility model is for a kind of energy-conservation ventilation fan that can change indoor-outdoor air is provided, and makes can replace from the heat (cold) of the muddy air of indoor discharge and send into the indoor fresh air, to reduce the loss of energy.
The utility model of realizing above-mentioned purpose also includes a blowing fan and has two air intakes and two air outlets, middlely separate and make the bellows in formation ectonexine wind district with a dividing plate except that including an exhaust fan; Inside and outside floor wind district respectively has an air intake and air outlet, and exhaust fan and blowing fan are separately positioned on air intake and the air outlet with one deck wind district; Place side by side mutually to be nested with and form the two air channels of spaced-apart spirality thin-walled thereby respectively be provided with one group in the ectonexine wind district of the utility model in bellows, and inside and outside two groups of two air channels interconnect at the spirality center.The utility model of structure like this, the fixed edge that the central dividing plate of mat bellows stretches out in bellows shell is fixed in wall hole or the window frame, and it is outdoor that the crosswind case that fan is housed is exposed to, and the opposite side bellows are positioned at indoor.
The utility model has the advantages that, because the utility model includes an exhaust fan and a blowing fan, so, one side is from indoor exhaust wind during use, simultaneously to the indoor fresh air of sending into, and the muddy air of discharging carries out convection current with the fresh air of sending in helical pair of air channel, the air of two kinds of different temperatures is by thin-walled generation interchange of heat in the convection process.Therefore, the utility model can be replaced room air on the one hand effectively, makes the fresh air in the inlet chamber have the temperature close with indoor environment on the other hand.Like this, both improved room air, and can prolong the application life of air-conditioner again and save the energy.
Embodiment of the present utility model is described specifically the utility model below in conjunction with embodiment as shown in drawings.
Description of drawings:
Fig. 1 is a forward generalized section of the present utility model;
Fig. 2 is a cross sectional representation of the present utility model.
Please consult Fig. 1, Fig. 2 simultaneously.See that by figure present embodiment has an exhaust fan 1, a blowing fan 8 and bellows that are made of the two air channels 14,15 of upper and lower cover plate 3,11, central dividing plate 4 and spirality.Central dividing plate 4 is divided into inside and outside two wind districts to bellows, and the zone between central dividing plate 4 and the upper cover plate 3 is the exogenous wind district, and the zone between the lower cover 11 is the Nei Feng district; The two air channels of spirality have upper and lower two groups, and exhaust blower 1 is equipped with at air intake 2 places that are positioned at the two air channels 14,15 of spirality in exogenous wind district, and ventilator 8 is equipped with at air outlet 7 places; The air intake 13 and the air outlet 9 that are positioned at the two air channels of spirality in Nei Feng district communicate with the room is indoor; The two air channels of upper and lower two groups of spiralitys interconnect by the through hole on the central dividing plate 4 in the spiral center.
When this present embodiment ventilation fan was installed, outside the room, the Nei Feng district was towards within doors the exogenous wind district that blower fan is housed, thus give in this ventilation fan, the flow direction of air draft is: after starting exhaust blower 1, exhaust blower is to indoor air draught, indoor muddy air A
