Abstract
The utility model relates to a bidirectional scavenger fan which is especially suitable for the ventilation and air exchange of relatively closed space. The utility model is mainly composed of an impeller with an inner ring structure and an outer ring structure, an inner and an outer wind channels which are isolated from each other and a preheating component. The inner ring and the outer ring of the impeller are connected into a whole by a flange-shaped circular ring. Indoor air is discharged out of a room via the inner wind channel under the function of the axial flow type blade of the inner ring of the blade wheel. Outdoor air is delivered into the room via the outer wind channel under the function of the centrifugal blade of the outer ring of the impeller. The air exchanging process of the simultaneous proceeding of air exhaust and air suction is accomplished. The wind outlet of the outer wind channel is provided with a PTC preheating component used for heating outdoor air, and the outdoor air is delivered into the room after the temperature of the outdoor air is improved.
Description
The utility model relates to a kind of ventilation fan, is applicable to the ventilation of multiple environment, is specially adapted to the ventilation in relative closure space.
Existing ventilation fan is divided into unidirectional and two-way two kinds.Dual direction ventilating fan wherein is to realize air-breathing respectively and two processes of exhaust by changing the motor sense of rotation, and can't realize the gas exchange process that air-breathing and exhaust is carried out simultaneously.So in the space of a relative closure, for example computer room, test treasured, meeting room, singing-hall wait the place just to need two ventilation fans to work simultaneously, discharge indoor vitiated air for one, another sucks outdoor fresh air, to reach satisfied ventilation effect.Not only increased cost of equipment but do like this, and brought many inconvenience to installation.
The purpose of this utility model is will provide a kind of can finish air-breathing simultaneously and bidirectional ventilated ventilation fans two processes of exhaust.It is only needed when just can discharge vitiated air from the space of sealing, to suck fresh air from the external world, to reach the purpose of bidirectional balanced ventilation along a direction rotation by the impeller of a special construction of a motoring.Indoor heat loss when preventing that winter from taking a breath, the utility model also is provided with the pre-warmware of outdoor air.
Characteristics of the present utility model are: ring and outer shroud two-part in impeller is divided into, and interior ring is made up of some axial--flow bladings, and outer shroud is made up of some centrifugal blades.The axial--flow blading of interior ring and the centrifugal blade of outer shroud connect in aggregates by a flange-like annulus.Corresponding with the inner and outer rings of impeller is inside and outside air channel.Indoor air is arranged to outdoor by interior air channel under the effect of axial--flow blading; Outdoor air is sent into indoor by outer air channel under the effect of centrifugal blade.Inside and outside air channel is separated by minute air duct and split-wind plate, so that two strands of air-flows do not disturb mutually.Exhaust outlet place in air channel is provided with the pre-warmware of PTC outside, with the heating chamber outer air, make its improve send into again after temperature indoor.
The utility model compared with prior art has following advantage:
1, can when discharging indoor air, suck outdoor fresh air, the scavenging efficiency height.In enclosed environment, use and to replace two existing ventilation fans.
2, when using summer, but forced air flow, the effect that reaches radiating and cooling, goes tide to dehumidify.When using in the winter time,, has the effect that reduces indoor heat loss by pre-warmware preheating cool air.
3, compact structure, simple installation
Now in conjunction with the accompanying drawings the utility model is further described;
Ring (5) in impeller in the accompanying drawing (6) is made up of several axial--flow bladings is formed outer shroud (3) by several centrifugal blades.The interior ring of impeller and outer shroud connect in aggregates by flange-like annulus (4).Impeller is driven by the motor (13) that is fixed on the support (16).With the interior ring of impeller and outer shroud corresponding in air channel (15) and outer air channel (10) by a minute air duct (9) and split-wind plate (12) separation.Air-flow in the interior air channel (17) is discharged outdoor through blinds (14) vertically; Air-flow in the outer air channel (18) moves along spiral-expanding shape wind path wall (8) after 90 ° of turnovers, and locates at exhaust outlet (2), sends into indoor after the pre-warmware of PTC (1) heating.Air sucking mouth on the face shield (7) is the bar shaped aperture plate.The section configuration of shell (11) is a rectangle.
Description of drawings is as follows:
Accompanying drawing 1 is a side cutaway view of the present utility model, and accompanying drawing 2 is the left view of accompanying drawing 1.
Claims (1)
1, a kind of dual direction ventilating fan is applicable to the ventilation of multiple environment, is specially adapted to the ventilation in relative closure space, it is characterized in that:
Ring (5) in impeller (6) is made up of several axial--flow bladings is formed outer shroud (3) by several centrifugal blades, and it is in aggregates that interior ring (5) and outer shroud (3) are connected by flange-like annulus (4), and by motor (13) driving of being fixed on the support (16);
Divide air duct (9) and split-wind plate (12) that air delivery passage is divided into interior air channel (15) and outer air channel (10), divide air duct (9) to match with the flange-like annulus (4) of impeller (6), the interior ring (5) of impeller (6) is linked with interior air channel (15), and outer shroud (3) links with outer air channel (10);
Outer air channel (10) is centrifugal direction through 90 ° of turnovers by axial transitions, and constitutes the air channel profile by spiral-expanding shape wind path wall (8), and the exhaust outlet (2) of outer air channel (10) is located at the ventilation fan bottom;
The exhaust outlet (2) of air channel (10) is located outside, and the pre-warmware of PTC (1) is set;
Air sucking mouth on the face shield (7) is the bar shaped aperture plate.
