Technical field
The present invention relates to constructure ventilation technical fields, more particularly, to a kind of outlet air of adjustable induction type fresh air system
Device.
Background technology
With scientific and technological progress and economic development, air-conditioning system is usually mounted in present building.But air-conditioning system
Only indoor gas is cooled down or heated up, gas or original gas do not change, simply by air-conditioning
System makes the temperature of room air change to meet the daily life needs of the mankind, to improve comfort level.Over time, room
Interior air inevitably becomes more and more dirty, influences the health of the mankind, just needs to carry out room air at this time
Displacement, outdoor is drained by the air of foul indoor, outdoor ozone is introduced it is indoor, traditionally, above-mentioned ventilation by window,
The devices such as exhaust fan or ventilation fan are realized.
In view of the shortcomings of conventional ventilation device or method, currently, there is a kind of fresh air system, including one-way flow is new
Wind system, bidirectional flow fresh air system and ground supply air system.Wherein one-way flow fresh air system include positive pressure type fresh air system and
Suction type fresh air system.Wherein, the operation principle of positive pressure type fresh air system is about：Using mechanical fan by outdoor fresh sky
Gas is forcibly sent into interior, and with being constantly blown into for fresh air, room pressure gradually increases so that gas is from building
Gap or dedicated gas vent in discharge, to realize displacement to room air.
But in summer, the temperature for the outdoor air that positive pressure type fresh air system is sent is higher than the temperature of room air, room
The humidity of outer air is more than the humidity of room air, and the outdoor air of higher temperature and higher levels of humidity is continuously got in
Apparent discomfort can be brought to the indoor mankind are lived in；When in winter, outdoor air that positive pressure type fresh air system is sent
Temperature be less than the temperature of room air, the humidity of outdoor air is less than the humidity of room air, lower temperature and compared with low humidity
Outdoor air continuously get in can be to living in the indoor mankind and bring apparent discomfort.
Therefore, the structure and composition for how improving positive pressure type fresh air system, to adjust the sky got in from exhaust apparatus
The temperature and humidity of gas, and then it is that the technology of those skilled in the art's urgent need to resolve is asked to weaken or avoid original discomfort
Topic.
Invention content
The purpose of the present invention is to provide a kind of exhaust apparatus of adjustable induction type fresh air system, which can
The structure and composition for improving positive pressure type fresh air system to adjust the temperature of the air got in from exhaust apparatus, and then weakens
Or avoid original discomfort.
In order to solve the above technical problems, technical solution provided by the invention is：
A kind of exhaust apparatus of adjustable induction type fresh air system, includes the internal diameter of fresh wind tube, the first aperture valve, outlet air end

It is commonly installed higher position indoors in view of the exhaust apparatus of positive pressure type fresh air system, such as roof or exterior wall
Top, when the first aperture valve 2 and/or the second aperture valve 4 are adjusted, will also be ascended a height operation using ladder, cumbersome, be
This, in one embodiment of the invention, the first aperture valve 2 is connect with the first adjusting driver plate 8 with reality by the first living hinge 7
The aperture that driver plate 8 adjusts the first aperture valve 2 is now adjusted by rotation first, the level height satisfaction of the first adjusting driver plate 8 works as people
Class station indoors on floor when it is accessible, the place within reach in the mankind is arranged in the first adjusting driver plate 8 so that Ren Leizhan
It indoors can easily, according to oneself requirement to the temperature and humidity of mixed gas, to opening for the first aperture valve 2 on floor
Degree is adjusted.
Further, in one embodiment of the invention, the second aperture valve 4 is adjusted by the second living hinge 9 and second
The connection of section driver plate 10 adjusts the aperture that driver plate 10 adjusts the second aperture valve 4 to realize by rotation second, and second adjusts driver plate 10
Level height meet when mankind station indoors on floor when it is accessible, by second adjust the setting of driver plate 10 mankind's tentacle can
And place so that mankind station indoors can easily, according to oneself wanting to the temperature and humidity of mixed gas on floor
It asks, the aperture of the second aperture valve 4 is adjusted.
Further, the first adjusting driver plate 8 can be connect with the second adjusting driver plate 10 with program control device, with realization to the
One adjusts the remote auto adjusting that driver plate 8 and second adjusts driver plate 10, improves the practicability and convenience of above-mentioned exhaust apparatus.
The maximum feature of exhaust apparatus provided by the invention is adjustable, and air quantity is adjustable and mixed wind is than adjustable.
In order to further increase spouting velocity when outdoor air is got in by outdoor, injection power is improved to generate more
High negative pressure degree, and higher volume of negative pressuren zone, finally to improve the mixing of outdoor air and room air, the one of the present invention
In a embodiment, exhaust apparatus provided by the invention further includes the second conical nozzle 14, the outlet air end of first conical nozzle 3
It is tightly connected with the air intake of second conical nozzle 14 to constitute Laval nozzle structure, according to aerodynamic principle,
Compared with single conical nozzle structure, Laval nozzle structure can significantly increase the spouting velocity of air-flow, reasonable for structure
Laval nozzle structure even the speed for spraying air-flow can be risen to supersonic speed, spouting velocity is bigger, and injection power is bigger,
The reduced pressure of negative pressuren zone is higher, and volume is also bigger, can improve mixability, combined amount of outdoor air and room air etc.
Deng.
