Abstract
The utility model relates to a dual-direction scavenger fan, the working principle of which is that: two ends of a shaft of an electromotor are provided with an axial-flow blade fan respectively. The blade angles of the two blade fans are reverse; when the electromotor is rotating towards a fixed direction, winds from two blade fans at two ends of the shaft of the electromotor are reversely directed, and the two blade fans at two ends of the shaft of the electromotor are also reversely directed. When in installation and use, one blade fan of the utility model of the dual-direction axial-flow scavenger fan expels and disperses dirt hot air above from a room or a vehicle to the air; and the other blade fan inbreathes fresh air outside the room or below the vehicle scatters the fresh air inside the room or the vehicle, thereby forming convective circulation of the air outside and inside the room and the vehicle and ensuring the air to be exchanged thoroughly. The effect of the utility model is better than an air condition and a single direction scavenger fan. The dual-direction scavenger fan has simple structure, convenient installation and use, low energy consumption and wide applicability.
Description
Technical field
The utility model relates to a kind of two-way scavenger fan.
Background technique
At present, for the air in the conditioning chamber or in the compartment, what generally use is air conditioner or ventilating fan.The air conditioner complex structure costs an arm and a leg, and its effect is to regulate indoor air temperature, but indoor air and outdoor air are fully exchanged, and does not reach the effect of inside and outside adjusting; And ventilating fan can only unidirectional air draft, indoor air is discharged into outdoor or opposite, and regulating action is also not obvious, and effect is not good enough.
Summary of the invention
The purpose of this utility model is to provide a kind of indoor and outdoor air that can make fully to exchange, with in the thorough conditioning chamber or a kind of two-way scavenger fan of air in a car compartment quality.
The two-way scavenger fan of setting is made up of the axial--flow blading fan at a motor and motor rotary shaft two ends for this reason, and the exhaust outlet of two axial--flow blading fans is towards on the contrary.The intake grill of diaxon streaming blade fan air intake conduit is also towards on the contrary, and with the exhaust outlet of fan separately towards opposite or vertical.Be provided with isolating plate between the diaxon streaming blade fan.The intake grill of the air intake conduit outside the axial--flow blading fan places outdoor or car can be established filter screen.
The two-way scavenger fan of the utility model, with coaxial mounted two blade fans that angle is opposite of motor drives, the blade fan of a postive direction angle can be discharged the dirty hot air of indoor top, leave to outdoor top: simultaneously another in the other direction the blade fan of angle flow to indoor below again in the air suction chamber with outdoor below.Indoor air and outdoor air convection circulation are fully exchanged, to improve IAQ.This machine compact structure is reasonable, easy to install, and energy consumption is low, applied range.
The utility model is described in further detail below in conjunction with drawings and Examples:
This figure is the structural representation of the two-way scavenger fan of the utility model.
5,7 intake grills among the figure, 9,10 air intake conduits, 2 motor rotary shafts, 3,4 blade fans, 6,8 blade fan exhaust outlets, 12 filter screens, 1 motor, 11 isolating plates.
Embodiment
As shown in the figure: the two-way scavenger fan of the utility model is made up of the axial-- flow blading fan 3,4 at motor 1 and motor rotary shaft 2 two ends.The exhaust outlet 6,8 of diaxon streaming blade fan 3,4 is towards on the contrary, both one in indoor or car, another is outside outdoor or car, the intake grill 5,7 of the air intake conduit 9,10 of diaxon streaming blade fan 3,4 is also towards on the contrary, and with the exhaust outlet 6,8 of fan separately towards vertical, exhaust outlet is in indoor or car, intake grill is outside outdoor or car, exhaust outlet is outside outdoor or car, and its intake grill is in indoor or car.Be provided with isolating plate 11 between the diaxon streaming blade fan 3,4, mix to avoid inside and outside air short circuit.Place on the intake grill 7 of outdoor axial--flow blading fan and can establish filter screen 12, in blocks dust, foreign material inlet chamber.
