Description
Technical field
The present invention relates to ventilation unit, particularly a kind of ceiling type ventilation equipment based on Coanda effect.
Background technology
Indoor ventilator unit is as the visual plant for improving indoor environment, to keeping the good humiture of room air, clear
Cleanliness and suitable speed play an important role, and are one of important factor in order of indoor air quality.Although present market
On indoor ventilator unit species it is various, but is all to be aerated ventilation by the mode of initial velocity jet mostly, can produce not
Comfortable blowing feeling.Especially for the hanging ventilation unit using blade shear flow, the installation of its hanging can take larger
The interior space, the rotation of blade can both influence normal illumination, and there is also certain potential safety hazard；The air-out of formula is sent under its is direct
Mode, easily cause uncomfortable blowing feeling to indoor occupant.
The content of the invention
The purpose of the present invention is overcome the deficiencies in the prior art, and provides a kind of ceiling type ventilation based on Coanda effect
Equipment.It solves uncomfortable blowing feeling, the circulation of indoor air flow inorganization caused by existing ceiling mounting type ventilation equipment work
The problems such as unstable is illuminated with caused by blade rotation.
The technical scheme is that：Ceiling type ventilation equipment based on Coanda effect, including top plate, Coanda are dish-like
Shell, arc flow guide sleeve, air exhauster, contiguous block and the annular mounting frame with filter screen.
The wallboard of the dish-like shell of Coanda is Coanda curved surface, and its small openend inward curl is formed with smooth surface
Annular flow guiding head, sinuous flow noise is produced to avoid air-flow from running into sharp object.
The outer openings of annular flow guide sleeve, an annular diversion trench is formed in the outside of annular flow guide sleeve, its inwall is arc
Shape pod apertures, the inwall of arc guiding hole are provided with the annular boss for being used for installing annular mounting frame, the annular installation with filter screen
Frame is arranged on the annular boss in arc guiding hole by screw.
The dish-like shell of Coanda is connected by a plurality of contiguous blocks with annular flow guide sleeve, during connection, the dish-like shell of Coanda
On annular flow guiding head extend into the annular diversion trench of annular flow guide sleeve, one end of contiguous block on the outside of annular flow guiding head with connecting
Connect, with being connected on the inside of the annular diversion trench small end of annular flow guide sleeve, contiguous block is evenly distributed on annular and led the other end of contiguous block
In chute, the outside of the annular flow guiding head on the dish-like shell of Coanda on the inside of the annular diversion trench small end of annular flow guide sleeve with forming
Round wind outlet.
The dish-like shell of Coanda is arranged on top plate by screw, shape between the inside panel and top plate of the dish-like shell of Coanda
Into air-inlet cavity, space is left between the big end of annular flow guide sleeve and top plate, arc guiding hole and air-inlet cavity on annular flow guide sleeve
Communicate, air exhauster is lifted on top plate and in the arc guiding hole on annular flow guide sleeve.
Further technical scheme is the present invention：Pendent lamp is lifted with annular mounting frame.
Further technical scheme is the present invention：One piece of transparent annular is provided with the wallboard of Coanda disc shaped shell
Plate, annular slab are provided with one piece of annular tabular LED.
The more further again technical scheme of the present invention is：Pendent lamp is lifted with annular mounting frame, in Coanda dish
The wallboard of shell is provided with one piece of bright annular slab, and annular slab is provided with one piece of annular tabular LED.
The present invention has the following advantages that compared with prior art：
1st, air-flow is soft, the sense of organization is good and comfortableness is good.The present invention using the ceiling mounting type ventilation unit for inducing stream,
Room air is pumped into air-inlet cavity by air exhauster from arc guiding hole, and from round wind outlet close to the dish-like outer shell outer wall section of Coanda
Grace flows out up to curved surface, and the air after outflow is driven Interior Space to follow by the water conservancy diversion of the dish-like outer shell outer wall Coanda curved surface of Coanda
Ring, so as to realize indoor a wide range of organized airflow circulating.With rotating the common wind sheared air and go out stream downwards using blade
Fan is compared, and has the blowing feeling of similar natural wind and more preferable air current composition, air-flow is softer than simple flowing out stream of penetrating, and realizes
Indoor a wide range of organized airflow circulating, avoids directly blowing from giving people the uncomfortable blowing feeling brought, is advantageous to construction one
Individual comfortable indoor environment.
2nd, energy consumption is small, noise is low.The present invention is induced using part fresh air, i.e., induces stream using low discharge, and inductivity is high
Up to 10-15 times, this air quantity for passing through air exhauster can be significantly reduced, and the power requirement of air exhauster can also be substantially reduced；By
Induced in round wind outlet and Coanda curved surface, it is possible to achieve produce common powerful fan with the induction air-out of low discharge small-power
Air-out effect, so as to reduce the consumption more than 30% of electric energy；Annular flow guiding head and arc flow guide sleeve with smooth surface can be kept away
Exempt from air-flow to run into sharp object and produce sinuous flow noise.
3rd, illumination and ventilation are taken into account.Illuminator can be installed on ventilation unit provided by the invention, because the present invention adopts
Be no leaf go out stream, avoid conventional fan due to blade rotate caused by illumination it is unstable, realize illumination with divulge information it is complete
U.S. combines, and makes indoor ceiling layout more attractive succinct.
4th, it is safe.Air exhauster is arranged in arc guiding hole, avoids the people because of caused by the high-speed rotation of blade
Body injures.
Below in conjunction with figure, the invention will be further described with embodiment.
