Description
Technical field
The present invention relates to ventilation unit field, air purification field, more particularly to a kind of forms ventilation valve and fresh air system
System, the forms ventilation valve is provided with solar cell, and can realize automatic shutter.
Background technology
With the development of society, requirement of the people to quality of life improves constantly.Wherein, air quality is that people are closed very much
One of an important factor for cutting.However, the air quality of living environment is mainly threatened by three aspects at present：
First, with the continuous propulsion of industrialization and urbanization, haze weather gradually increases, under causing air quality serious
Drop, the especially increase of PM2.5 solid contents, these solid particles cause respiratory disease, disease of cardiovascular system,
The inflammation such as the diseases such as hematological system, reproductive system, sphagitis pulmonary emphysema, asthma, rhinitis, bronchitis；
Secondth, various house fitting-ups can also distribute substantial amounts of volatile organic matter, such as formaldehyde, and these pollutants may draw
Play allergic dermatitis, color spot, even necrosis, bronchial astehma etc.；
3rd, (as lacked room with good ventilation) in enclosed environment, the expiration of people can cause the carbon dioxide in air
Content increases over time and constantly, thus stimulates the respiratory center of people, causes to be short of breath, and flue gas soakage increases
Add, or even the symptoms such as headache, unconsciousness can be caused.
In order to improve above-mentioned three aspects air quality problems, the air quality of people's living environment is improved, it is more next in recent years
More families starts to install VMC.VMC general principle passes through efficient filter from outdoor suction air
(HEPA) filtering, interior will be discharged in the air totally cleaned.Other side by second-rate air from room simultaneously
Discharge.
Therefore, there is VMC following both sides to act on：
Firstth, the solid particle in air is reduced；
Secondth, the carbon dioxide in air is reduced.
It is pointed out that according to the general principle of VMC, it is necessary to which the opposite side in room installs air bleeding valve, general
Second-rate air discharge is outdoor.In order to reduce the destruction to room, ventilation valve is mostly installed on forms, referred to as forms
Ventilation valve.Existing logical forms air-valve has many forms, but be usually present two it is obvious the shortcomings that：
Firstth, automatic shutter is unable to, thus causes VMC outdoor air usually occur when small air quantity is run and pours in down a chimney
To interior, and then room air is caused to be contaminated；
Secondth, the discharge directions of gas outlet are horizontal direction, thus in the case of rainy weather, rainwater entrance usually occur
Interior, and then indoor object may be caused moist.
Based on above-mentioned two shortcoming, need to be proposed a kind of new forms ventilation valve, it is above-mentioned of the prior art to solve
Problem.
The content of the invention
The technical problem to be solved in the present invention is, one kind installation is simple and can realize controllable opening and closing and without additional power supply
The forms ventilation valve of power supply.
Solve above-mentioned technical problem, the invention provides a kind of forms ventilation valve, including：It is located at the room of window both sides respectively
Internal and outdoor, the chamber interior is indoor gas is collected to the outdoor, and the outdoor is to by collection
Gas discharges, and a ventilation unit, in addition to a drive division is provided between the chamber interior and the outdoor, to drive
The ventilation unit is voluntarily opened and closed.By installing forms ventilation valve in forms, due to being provided with drive division on forms ventilation valve, lead to
The portion of overdriving can realize the controlled opening and closing of ventilation valve, at the same with existing VMC slitless connection, opening and closing signal thereon
Controlled in wireless is passed through by the main frame of VMC.Forms ventilation valve can realize controllable opening and closing, avoid ventilation valve without using
When dirty wind, cold wind pours in down a chimney.
Further, the drive division is the Driven by Solar Energy for being installed on the outdoor, the power supply required for drive division
There is provided by solar cell, without providing extra power supply, installation is relatively simple.
Further, the outdoor is fixed on window by snap fastener and the chamber interior, without to existing
Window carries out larger improvement, in order to realize that air is discharged to outdoor from interior, it is only necessary to sets a certain size in window-glass in advance
Rectangle air channel.
Further, the outdoor discharges gas by exhaust passage vertically downward, can reduce vertically downward
Influence of the outer gas stream to exhaust., will not because the discharge directions of its gas outlet are vertical direction, therefore in the case of rainy weather
Cause indoor object moist.
Further, the ventilation unit also includes：To adjust the gear gas portion of ventilation angle, ventilation is realized by keeping off gas portion
The opening and closing in road.
Further, the gear gas portion can be adjusted opening/closing in 0-90 ° of angle, that is, meet vertical closing and horizontal opening
State so that air output is adjustable.
Further, the chamber interior includes：Indoor inlet channel, indoor air inlet grid plate,
The indoor air inlet grid plate is installed on the air inlet opening position of the indoor inlet channel.Indoor inlet channel is main
Play a part of guiding air-flow, the throughput of indoor air inlet grid plate control air inlet.
Further, the outdoor includes：Outdoor discharge screen, outdoor discharge passage, solar cell paster,
The outdoor discharge screen is installed at the air outlet position of the outdoor discharge passage,
The solar cell paster is laid according to the outer shape of the outdoor discharge passage.
The solar cell paster is due in the environment in outdoor, so can convert solar energy into electrical energy daytime,
The normal operation of drive division is provided, and can be by unnecessary power storage in energy-storage battery chip.
Further, the drive division includes：Stepper motor and rotation gear gas blade,
For the stepper motor to drive the rotation gear gas blade to rotate, the rotation gear gas blade passes through biography thereon
Moving gear realizes rotation,
The rotation gear gas blade is fixed on the rotating vane mounting hole of the outdoor by rotating vane installation axle.
Present invention also offers a kind of VMC, including described forms ventilation valve, the VMC is passing through
Forms ventilation valve described in controlled in wireless is opened and closed.The main frame of VMC can realize Remote control.
Beneficial effects of the present invention：
1) the forms ventilation valve in the present invention, drive division are driven through and installed between the chamber interior and the outdoor
There is a ventilation unit ventilation unit to be voluntarily opened and closed.So that forms ventilation valve can realize controllable opening and closing, ventilation valve is avoided not
The situation that dirty wind, cold wind during use pour in down a chimney occurs, simultaneously because drive division is solar charging/discharging, without providing volume
Outer power supply.
2) the forms ventilation valve installation in the present invention is relatively simple, passes through snap fastener and the room by the outdoor
Inside is fixed on window, without carrying out larger improvement to existing window, in order to realize that air is discharged to outdoor from interior, is only needed
Shift to an earlier date and a certain size rectangle air channel is set in window-glass.
3) outdoor of the forms ventilation valve in the present invention, because the discharge directions of its gas outlet are vertical direction, therefore
In the case of rainy weather, indoor object will not be caused moist.
4) the forms ventilation valve in the present invention can be directly used in VMC, be realized by the main frame of VMC long-range
Remote control, it is easy to operate.Meanwhile thus long-range opening and closing operations effectively prevent VMC and usually go out when small air quantity is run
Existing outdoor air pours in down a chimney to interior, and then the situation for causing room air to be contaminated.
