Description
Technical field
The utility model belongs to building member, is specifically related to one and is ensureing, on safe and reliable basis, to possess the energy-saving air door of effect of natural ventilation.
Background technology
In modern construction engineering, in order to be applicable to consumer demand, or the function of building needs itself, increasing large scale door and window appears in these buildings.But these large scale door and windows bring convenience time attractive in appearance, also can bring the problem of certain human settlement's quality! According to statistics, there is time of 80% the people of interior works in indoor, in most cases interior door is all in closed condition, the not good indoor air quality (Indoor Air Quality IAQ) that makes of room ventilation ventilation is inferior, particularly in early summer with early autumn outdoor air nice and cool or indoor sultry, but while being not suitable for opening fan or air-conditioning, the sultry dirt of room air, atmosphere draught-free, has had a strong impact on the quality of people's live and works.
Existing room uses door only in the situation that opening completely, just there is the effect of ventilation, but in office building, staff is in order to ensure the space of a secret, door most of time, all in closed condition, so just can not ensure indoor air quality; In housing construction, most people is stayed out daytime, just go home evening, make the shut-in time of every Tianmen reach more than 10 hour, room is just isolated from the outside like this, indoor air just can not carry out ventilation with ambient atmosphere, causes indoor air quality Quality Down, to people's the healthy adverse influence that causes.
Utility model content
For existing building, the deficiency that door exists is installed, technical problem to be solved in the utility model is just to provide energy-saving air door, and it is by means of natural ventilation, in off position under, can realize ventilation process.
Technical problem to be solved in the utility model is to realize by such technical scheme, and it includes a body, is provided with ventilation opening, bottom is provided with lower ventilation opening, in upper ventilation opening and lower ventilation opening inside casing, filtering screen is installed on door body top.
Due to the effect of hot pressing, outdoor fresh air is in lower ventilation opening flowed into chamber, and indoor foul atmosphere flows out from upper ventilation opening.It is indoor that filtering screen stops that outdoor dirt enters, and has the effect of peep-proof simultaneously.
Owing to having adopted technique scheme, the utlity model has following advantage: in off position, can realize ventilation process, thereby ensure indoor air quality, be conducive to people's physical and mental health.The utility model is not only applicable to house, the many and long-time laboratory stopping of personnel for pyrotoxin, and indoor and outdoor temperature is poor greatly, personnel concentrate, ventilation volume requires high bathroom and the office in inner region or needs the room of all-year-around cooling applicable equally.
Brief description of the drawings
Brief description of the drawings of the present utility model is as follows:
Fig. 1 is the front view of the utility model structure;
Fig. 2 is the axonometric drawing of the utility model structure.
In figure: 1. a body; 2. filtering screen; 3. upper wind door; 4. lower wind door; 5. go up ventilation opening; 6. descend ventilation opening; 7. air door lock; 8. air door spring; 9. the first groove; 10. the second groove
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1, the utility model includes a body 1, is provided with ventilation opening 5, bottom is provided with lower ventilation opening 6, in upper ventilation opening 5 and lower ventilation opening 6 inside casings, filtering screen 2 is installed on door body 1 top.
Filtering screen 2 can be extracted out along horizontal from ventilation opening frame wall, convenient for dismounting and washing.
Operating principle of the present utility model is as follows: suppose that between ventilation opening 5 and ventilation opening 6 central points, difference in height is h, the static pressure of establishing outside ventilation opening 5 and ventilation opening 6 is respectively P
5, P
6, the static pressure in ventilation opening 5 and ventilation opening 6 is respectively P

w, due to t
n> t

According to hydrostatics principle, the inside and outside differential pressure of ventilation opening 5 is

From above formula, at Δ P

5> 0, air will flow out from ventilation opening 5.Along with outwards flowing of room air, indoor static pressure reduces gradually.(P
6＇-P
6) become and be less than zero from equalling zero.At this moment indoor-outdoor air is just flowed into indoorly by ventilation opening 6, until the intake of ventilation opening 6 is while equaling the exhaust air rate of ventilation opening 5, indoor static pressure just keeps stablizing.Due to ventilation opening 6 air intakes, Δ P
6< 0; Ventilation opening 5 air drafts, Δ P
5> 0.
So determine:
ΔP

This shows the depth displacement h of ventilation opening 5 and ventilation opening 6 and the poor (ρ of atmospheric density of indoor and outdoor

n) product can be used as the mobile power of indoor-outdoor air, thereby reach the object of room ventilation ventilation.Because not needing additional electric fixtures, the utility model carries out ventilation, so there is energy-conservation effect.
As shown in Figure 2, in upper ventilation opening 5 and lower ventilation opening 6, with filtering screen 2, upper wind door 3 and the lower wind door 4 that can move up and down are housed abreast, upper wind door, lower wind door are all provided with air door lock 7.Air door lock 7 has anti-theft function.
Air door spring 8 is equipped with in the side upper end of upper wind door 3 and lower wind door 4, offers respectively the first groove 9 and the second groove 10 at the position up and down of ventilation opening side frame wall, and air door spring 8 coordinates with the first groove 9 and the second groove 10, slides spacing to implement air door.
As shown in Figure 2, upper wind door and lower wind door are in opening, and upper wind door 3 moves down, lower wind door 4 moves up, and air door spring 8 separates with the first groove 9, under full-gear, air door spring 8 falls into the second groove 10, thereby keeps upper wind door 3 and lower wind door 4 can not glide.At this moment, the air that outside temperature is lower will be in lower ventilation opening 6 flowed into chamber, the air that interior temperature is higher will be in upper ventilation opening 5 delivery chamber, it is indoor that filtering screen 2 can stop that outdoor dirt enters, so just form convection current indoor, outdoor air will be taken away indoor unnecessary heat and pollutant, thereby builds an indoor environment that comfort level is higher.
While closing air door, air door spring 8 and the first groove 9 coincide, and keep upper wind door 3 and lower wind door 4 can not glide.
