Description
Technical field
The present invention relates to ventilation fan, particularly Coanda fin ventilation fan.
Background technology
Ventilation fan is widely used in industry, family and public place, is mainly expired by the exchange of indoor and outdoor air
Sufficient difference in functionality room is to the requirement such as indoor temperature and humidity, cleannes.Existing ventilation fan is mainly rotated using flabellum to shear
Pressure difference is taken a breath to realize before and after air-flow produces.Although ventilation fan species is various, all there is big noise, air turbulence and be not easy clear
The shortcomings of washing.With ventilation fan in the case of indoor air intake, tradition change fan air intake air turbulence room air is disturbed it is larger,
The blowing feeling of indoor occupant is easily caused, influences the thermal comfort of people；In the case that Wind Volume is taken a breath, ventilation ventilating fan is wanted
Ask high, while easily produce noise, give people discomfort.
The content of the invention
The purpose of the present invention is overcome the deficiencies in the prior art, and provides a kind of Coanda fin ventilation fan.It is solved
Existing ventilation fan air intake air turbulence, noise is big in the case of Wind Volume air inlet the problem of.
The technical scheme is that：Coanda fin ventilation fan, including cabinet, Coanda fin, two pieces of half of shape sections
Grace reaches fin, air exhauster and gauze.
Cabinet includes blower fan chamber, pressure stabilizing cavity and for installing the framework of Coanda fin and half of shape Coanda fin, cabinet
It is communicated with body front panel and cabinet rear board to the medial extremity of the air admission hole of blower fan chamber, cabinet front panel and cabinet rear board
Two parallel guide rails are respectively equipped with face, two pieces of movable baffle plates are installed between two guide rails, moving stop can open or
Air admission hole is closed, gauze is arranged on framework, and positioned at the back side of Coanda fin bar shaped air outlet.
Pressure stabilizing cavity is located at the upper end of blower fan chamber and connected by ventilating opening with blower fan chamber, and framework is located at the upper end of pressure stabilizing cavity.
Coanda fin includes V-arrangement bottom, arc top and contiguous block；Arc top is connected with V-arrangement bottom by contiguous block
One is connected in, and forms the body endoporus of Coanda fin；It is provided between the openend of V-arrangement bottom and the openend on arc top
Bar shaped air outlet；The outer wall of V-arrangement bottom is Coanda curved surface.
Half of shape Coanda fin is the half of Coanda fin, and it is with the central plane y of Coanda fin to partly splitting
Form.
Air exhauster is arranged on the upper end of blower fan intracavitary.Coanda fin and half of shape Coanda fin are arranged in framework,
Its one end connects with pressure stabilizing cavity, and the other end is connected with framework wallboard and closed by framework wallboard；Two pieces of half of shape Coanda wings
Piece is connected with the wallboard of framework and forms tube cavity respectively, and Coanda fin is located between two pieces of half of shape Coanda fins.
Further technical scheme is the present invention：Pressure stabilizing cavity is horizontally set on above blower fan chamber, Coanda fin and one side of something
Shape Coanda fin is vertically arranged in framework.
Further technical scheme is the present invention：Pressure stabilizing cavity is vertically arranged on the wallboard of blower fan chamber top frame, section
Grace is horizontally set in framework up to fin and half of shape Coanda fin.
Sketch the use of the present invention：
The present invention is used for indoor and outdoor air and exchanged, and in the indoor wall of cabinet insertion, framework communicates with outdoor.Work as Coanda
Fin used in air exchange fan is when air intake, in the bar shaped air outlet direction faced chamber of Coanda fin, when Coanda fin used in air exchange fan
When air draft, outside the bar shaped air outlet direction faced chamber of Coanda fin.
During work, start air exhauster, air enters blower fan chamber by the air admission hole on cabinet, enters back into pressure stabilizing cavity, make gas
Levelling delays, and enters back into Coanda fin tube body in hole, is blown out from bar shaped air outlet.The wind energy of blowout plays the work of guiding air-flow
With the air guiding that (preceding) end after framework is opened wide to place flows to (rear) end before framework and opened wide and locates.
The present invention has the following advantages that compared with prior art：
1st, ventilation is efficient, and the outer wall of Coanda fin is the Coanda curved surface for water conservancy diversion, and its wall attachment effect uses general mood
Stream is significantly improved.This guide face based on Coanda curved surface ensure that the steady of air-flow, be advantageous to the induction of air-flow,
Induction the ratio between total blast volume and import air quantity are that induction ratio is up to 15 times.
2nd, air-flow is soft, bar shaped air outlet compared with circular air outlet, the air-flow of blowout evenly, it is soft.
3rd, various informative, the present invention both may be used as new fan, it is also possible to make ventilating fan；Air intake opening direction is various, can
Select indoor or outdoors as air intake environment according to actual conditions, avoid using it is contaminated be used as induced draft, prevent from causing
Indoor environment or ventilation fan internal contamination, IAQ is influenceed, reduce fan performance and service life；Discharge pipe has level
With vertical two kinds of arrangements, exit flow respectively have horizontal slice and it is longitudinal layered the characteristics of；Length, the quantity of discharge pipe
It can be changed with spacing according to the requirement of air quantity and installation.
4th, it is safe to use, induction type air-out is employed, on-bladed rotation, avoids the meaning because of caused by blade high-speed rotation
Outer injury, safety coefficient are high.
5th, easy to clean, the present invention has the characteristics of built in on-bladed and air exhauster, and the exposed cabinet body structure in environment is simple,
Shape is regular, free of demolition can clean；It is improper due to cleaning to be avoided built in air exhauster, and water is immersed in inside motor and makes it impaired
Situation.
Below in conjunction with drawings and examples, the invention will be further described.
