Description
Technical field
The present invention relates to a kind of apartment building, is a kind of ventilating system particularly.
Background technology
Apartment is a kind of common residential building body, and apartment is built in the business district of prosperity more, limited in order to save
Soil space, traditional apartment are in two-sided building more, i.e. the north and south face of building body is each provided with a face house, the building body of this structure
It is not easy to divulge information, each room only has a direction to offer window, and air can not form convection current；When opening the door, windowing being divulged information, respectively
The smell in individual room is mingled in corridor, or even some smells smoked in room also adulterate in atmosphere, can not effectively arrange
Go out, not only bad for the flowing of air, can also influence the neighbours of surrounding, under the room air quality for causing whole floor
Drop, is adversely affected to the resident to live in it；In addition, when opening the door ventilation, indoor privacy is had a greatly reduced quality again, for one
For a little solitary schoolgirls, security cannot be guaranteed.
The content of the invention
In view of the above-mentioned problems, the present invention provides a kind of apartment bus type ventilating system, the ventilating system can be protected effectively
Room ventilation is demonstrate,proved, and door need not be opened, has both protected individual privacy and can enough to improve room air, while smell can be prevented
Crossfire, ensure air quality, improve smell environment in corridor.
To solve the above problems, the technical solution adopted in the present invention is：This apartment bus type ventilating system includes
Separated time part and bus portion；
Separated time is partially installed in each room of apartment, and separated time part includes ventilator and ventilating duct, in ventilator
Ventilation pore is offered on barrel；The end of registering one's residence of the ventilating duct connects with ventilator, goes out family end and passes room from wall, is going out
Family end taps out unidirectional air inlet pipe and one-way exhaust pipe, unidirectional air inlet pipe and one-way exhaust pipe airtight partition；
Bus portion includes air ducting and air-guiding aisle, and what the air-guiding aisle included laid out in parallel and mutually completely cut off enters
Air channel and exhausting duct, each unit is tightly connected to the air inlet duct, Lou Ti with each unidirectional air inlet pipe of house type in building body
Interior each unit is tightly connected to the exhausting duct with each one-way exhaust pipe of house type；
Air-guiding aisle is vertical to be arranged in unit wall, and the lower end of air-guiding aisle extends to building body bottom, in air-guiding aisle
Lower end is provided with fluid-tight blowoff valve；The upper end of air-guiding aisle extends at the top of building body and is fixedly connected with air ducting, in air intake
The upper end of road and exhausting duct is provided with corresponding unidirectional valve；
The air ducting includes horizontal positioned guide duct, and the front end bore of guide duct is less than rear end bore；Guide duct
Front and back end towards with the direction of window matches in room in corresponding unit；Air-guiding aisle is arranged on the tube wall of guide duct, is being led
Guide vane is provided with airduct.
The beneficial effects of the invention are as follows：This apartment bus type ventilating system can be effectively improved the air in tenements
Quality；When the wind in the external world blows to interior from window, the air-flow synchronization of high-speed motion flows to rear end, wind from the front end of guide duct
Guide vane is blown afloat when power is passed through, guide vane is close to the side wall of guide duct；It can be seen from hydrodynamics, the upper end meeting of air-guiding aisle
Produce low pressure, now the gas in air-guiding aisle by continually from exhausting duct extract out, therefore the air in each room by from
Ventilator suctions out；The air flow from window to ventilator is now formed in room, realizes the ventilation of house interior, even if
Room door is not opened, can also realize the ventilation of interior, and then substantially improves the air quality in room；Each room
Interior gas is discharged from exclusive one-way exhaust pipe, is not in cross pollution or is mixed, and will not pollute the air in corridor, i.e.,
Room someone in part is smoked, also do not interfere with the neighbours of surrounding；
When the wind in the external world is reverse, air-flow blows to front end from the rear end of guide duct, and blows guide vane；The edge card of guide vane exists
The upper end of air-guiding aisle, now air-flow be blocked, the air-flow blown from rear end endlessly pours in from air inlet duct, finally shunts
Into the unidirectional air inlet pipe in each room；Gas flows into room from each ventilating duct and ventilator, then is discharged from window；Entirely
During, extraneous air directly blows into room, and the air intake passage in each room is relatively independent, is not in the crossfire of smell,
Air quality has been effectively ensured, has effectively prevented the poor pollution of air.
Above two wind direction, effective convection current can be completed by closing in the room of door, be not in situation hair of feeling oppressed
It is raw, while the input and output gas in each room is relatively independent, situations such as in the absence of poor pollution, mutual taint of odour, both protect individual
Privacy, it also avoid bothering the neighbours of surrounding；The system is easy for construction, and cost is cheap, more facilitates in apartment body
Middle popularization.
Preferably, the ventilator is arranged on the both sides of a face wall of face window；The structure can effectively reduce room
Interior air flow dead angle, promotion room air is comprehensive, thoroughly flows.
As further preferred, it is provided with the ventilator except mosquito net cylinder, essence is installed in the upper end except mosquito net cylinder
Oil stock box；Air-flow from ventilator be blown into room when, except mosquito net cylinder can effectively prevent the debris of winged insect, dust, catkin from flying into,
Ensure the cleanliness factor in room, while gas flows, the essential oil permeated on except mosquito net cylinder can volatilize with the wind, improve air
Quality, a pure and fresh air environment is provided for client.
Preferably, the junction of guide duct and air-guiding aisle is provided with cutting runner；Wind-force drives cutting runner high
Speed rotates, and by the light weight sundries being mingled with air cutting, separation, and then prevents debris to be stuck in air-guiding aisle or enter unidirectionally to enter
In tracheae.
Preferably, the guide vane is hinged on the top of guide duct internal perisporium, anterior in hinged place sets limited location
Tooth, limiting tooth it is spacing under, the guide vane only can rotate 110 degree forward from the horizontal level at guide duct rear portion；Limiting tooth
Strong support can be provided for guide vane, effectively prevent guide vane to be broken, while can ensure that gas efficiently pours in air intake
Road.
Preferably, the rear end of the guide duct is arranged to bell mouth shape；In order to strengthen air draught effect.
