Description

Koln reaches fin ventilation fan
Technical field
The present invention relates to ventilation fan, particularly Koln reaches fin ventilation fan.
Background technique
Ventilation fan is widely used in industry, family and public place, and the exchange mainly through indoor and outdoor air meets difference in functionality room to the requirement such as indoor temperature and humidity, turbidity test.Existing ventilation fan mainly utilizes flabellum to rotate pressure reduction before and after shear flow generation and realizes taking a breath.Although ventilation fan is of a great variety, all have that noise is large, a shortcoming such as air turbulence and non-easy cleaning.When with ventilation fan to indoor air intake, tradition changes fan air intake air turbulence to indoor air disturbance comparatively greatly, easily causes the blowing feeling of indoor occupant, affects the thermal comfort of people; When Wind Volume ventilation, high to the requirement of ventilation ventilating fan, easily produce noise, to people's discomfort simultaneously.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, and provide a kind of Koln to reach fin ventilation fan.It solve existing ventilation fan air intake air turbulence, the problem that noise is large when Wind Volume air inlet.
Technological scheme of the present invention is: Koln reaches fin ventilation fan, comprises cabinet, Koln reaches fin, two pieces of half of shape Koln reach fin, induced draft fan and gauze.
Cabinet comprises blower fan chamber, pressure stabilizing cavity and is used for installing Koln and reaches the framework that fin and half of shape Koln reach fin, cabinet front panel and cabinet rear board are provided with the inlet hole being communicated to blower fan chamber, the guide rail that cabinet front panel is parallel with the inner side end of cabinet rear board being respectively equipped with two, article two, two pieces of sideboards are installed between guide rail, moving stop can open or close inlet hole, gauze is arranged on framework, and is positioned at the back side that Koln reaches fin bar shaped exhaust outlet.
Pressure stabilizing cavity is located at the upper end in blower fan chamber and is communicated with blower fan chamber by ventilated port, and framework is located at the upper end of pressure stabilizing cavity.
Koln reaches fin and comprises V-arrangement bottom, arc top and contiguous block; Arc top and V-arrangement bottom are connected as one by contiguous block, and form the body endoporus that Koln reaches fin; Bar shaped exhaust outlet is provided with between the opening end of V-arrangement bottom and the opening end on arc top; The outer wall of V-arrangement bottom is that Koln reaches curved surface.
It is the half that Koln reaches fin that half of shape Koln reaches fin, and its central plane y reaching fin with Koln forms partly cutting open.
Induced draft fan is arranged on the upper end in blower fan chamber.Koln reaches fin and half of shape Koln and reaches fin and be arranged in framework, and its one end is communicated with pressure stabilizing cavity, and the other end is connected with framework wallboard and passes through framework wallboard to be closed; Two pieces of half of shape Koln reach fin and are connected with the wallboard of framework respectively and form tube cavity, and Koln reaches fin and is located at two pieces of half of shape Koln and reaches between fin.
The further technological scheme of the present invention is: pressure stabilizing cavity is horizontally set on above blower fan chamber, and Koln reaches fin and half of shape Koln and reaches fin and be vertically arranged in framework.
The present invention further technological scheme is: pressure stabilizing cavity is vertically arranged on the wallboard of blower fan chamber top frame, and Koln reaches fin and half of shape Koln and reaches fin and be horizontally set in framework.
Sketch use of the present invention:
The present invention is used for indoor and outdoor air and exchanges, and cabinet embeds in indoor wall, and framework communicates with outdoor.When Koln reaches fin used in air exchange fan in air intake, Koln reaches in the bar shaped exhaust outlet direction faced chamber of fin, and when Koln reaches fin used in air exchange fan in air draft, Koln reaches outside the bar shaped exhaust outlet direction faced chamber of fin.
During work, start induced draft fan, air enters blower fan chamber by the inlet hole on cabinet, then enters pressure stabilizing cavity, makes air-flow mild, then enters Koln and reach in fin body endoporus, blows out from bar shaped exhaust outlet.The wind energy of blowout plays the effect guiding air-flow, and before the air (front) end after framework being opened wide place guides and flows to framework, (afterwards) end opens wide place.
The present invention compared with prior art tool has the following advantages:
1, ventilate efficient, the outer wall that Koln reaches fin is reach curved surface for the Koln of water conservancy diversion, and its wall attachment effect is used general mood stream and significantly improved.This guide face reaching curved surface based on Koln ensure that the steady of air-flow, is conducive to the induction of air-flow, and the ratio of induction total blast volume and import air quantity and induction ratio are up to 15 times.
2, air-flow is soft, bar shaped exhaust outlet compared with circular exhaust outlet, the air-flow of blowout evenly, soft.
3, various informative, the present invention both can be used as new fan, also can be used as ventilating fan; Air intake opening direction is various, indoor or outdoors can be selected as air intake environment according to actual conditions, avoid use contaminated as induced draft, prevent from causing indoor environment or ventilation fan internal contamination, affect IAQ, reduce fan performance and service life; Air outlet tube has level and vertical two kinds of arrangements, and exit flow has horizontal slice and longitudinal layered feature respectively; Length, the quantity and spacing of air outlet tube all can change according to the requirement of air quantity and installation.
4, use safety, have employed induction type air-out, and on-bladed rotates, and avoid the unexpected injury caused because of blade high speed rotating, safety coefficient is high.
5, easy to clean, the present invention has on-bladed and the built-in feature of induced draft fan, and the exposed cabinet body structure at environment is simple, and shape is regular, can exempt from disassembly, cleaning; Induced draft fan is built-in to be avoided due to clean improper, and water is immersed in the situation making it impaired inside motor
