Valve, for installation and maintenance process in adjust each air outlet air quantity, need to adjust air quantity relative difficulty in use, in this regard,
Also scheme discloses autocontrol valve, but the final experience effect of the valve use process is bad.
Utility model content
The purpose of this utility model is to provide a kind of air outlet air volume adjustable central air-conditioning, can adjust outlet air one's intention as revealed in what one says
Amount, and outlet air is uniform after adjusting.
Technical solution used by air outlet air volume adjustable central air-conditioning disclosed by the utility model is：A kind of air outlet
Air volume adjustable central air-conditioning is opened on the ventilation duct including unit, ventilation duct and the plenum chamber for connecting unit and ventilation duct
Equipped with multiple air outlets, multiple volume adjusting apparatus corresponding with air outlet are equipped in the ventilation duct, by air-flow direction,
The volume adjusting apparatus is set to corresponding air outlet upstream, and the volume adjusting apparatus includes first gear and first gear
Multiple second gears of engagement and the motor of driving first gear rotation, multiple second gears are set around first gear
It sets, each second gear army is respectively connected with flat blade, and multiple blades are radially arranged along ventilation duct.
Preferably, the blade is fan-shaped, including small head end and stub end, and the small head end is fixed on the second tooth
Wheel.
Preferably, the blade quantity is at least 5.
Preferably, air diffuser is set at the air outlet.
Preferably, the first gear and second gear are intermeshing bevel gear.
Preferably, the first gear is turbine, and the second gear is the worm screw being meshed with first gear.
The beneficial effect of air outlet air volume adjustable central air-conditioning disclosed by the utility model is：Unit generates low temperature or height
Warm air, low temperature or high temperature air enter ventilation duct through plenum chamber, and flow out eventually by air outlet, and in the process, air quantity is adjusted
Motor driven first gear turns an angle in device, and multiple second gears and corresponding blade is driven to turn an angle,
After flat blade rotation, the gap width between blade and blade changes, and then the air for changing ventilation duct effectively flows
Logical area, realizes the adjusting of the air quantity of air outlet, simultaneously as air passes through from the gap between multiple blades, makes to have leisure
Gas distribution is relatively uniform, improves comfort.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model air outlet air volume adjustable central air-conditioning；
Fig. 2 is the structural schematic diagram of the utility model volume adjusting apparatus.
Specific embodiment
The utility model is further elaborated and is illustrated with Figure of description combined with specific embodiments below：Please refer to figure
1, a kind of air outlet air volume adjustable central air-conditioning, including unit 10, ventilation duct 20 and connection unit 10 and ventilation duct 20
Plenum chamber 30, for unit 10 for heating or cooling air, the air after heating or refrigeration enters plenum chamber 30, the plenum chamber
30 for steady air flow and reduction airstream vibration, while increasing static pressure, and air enters ventilation duct 20 later, opens up on ventilation duct 20
There are multiple air outlets 50, air is finally flowed out from air outlet 50.
Multiple volume adjusting apparatus 40 corresponding with air outlet 50, the volume adjusting apparatus are equipped in the ventilation duct 20
40 are fixed on 20 inner wall of ventilation duct by tripod, by air-flow direction, the volume adjusting apparatus 40 be set to it is corresponding go out
50 upstream of air port, the volume adjusting apparatus 40 include first gear 41, engaged with first gear 1 multiple second gears 42,
The motor 43 that the blade and driving first gear 41 for being fixed on second gear 42 rotate.
Multiple second gears 42 are arranged around first gear 41,41 axis of first gear and 20 center of ventilation duct
Axis is overlapped, i.e., the described first gear 41 is fixed on 20 center of ventilation duct, and each second gear 42 passes through connecting rod 45
It is connected with flat blade 44, for multiple blades 44 along the radial arrangement of ventilation duct 20, the present embodiment, the blade 44 is fan
Shape is gradually tapered up from one end towards the other end, forms a corresponding small head end and stub end, and the blade 44 is equipped at least 5
Piece, and the gap width between multiple blades is equal.
In the present embodiment, the first gear 41 and second gear 42 are intermeshing bevel gear, and the two is in 90 degree of cloth
It sets, so that the second gear 42 is perpendicular to 20 central axis of ventilation duct.In other embodiments, the first gear 41 is whirlpool
Wheel, the wheel of the second tooth 42 are the worm screw being meshed with first gear 41, and above two scheme can be achieved to rotate blade 44
The change of angle.
Air diffuser 60 is set at the air outlet 50, the air diffuser 60 further disperses air, so that air distribution is equal
It is even.
In work, unit 10 generates low temperature or high temperature air, low temperature or high temperature air are sent into after 30 pressure stabilizing of plenum chamber and are led to
Air hose 20, and flowed out eventually by air outlet 50, in the process, the rotation of motor driven first gear 41 one in volume adjusting apparatus 40
Determine angle, multiple second gears 42 and corresponding blade 44 is driven to turn an angle, after flat blade 44 rotates, blade
Gap width between 44 and blade 44 changes, and then changes the air valid circulation area of ventilation duct 20, realizes outlet air
The adjusting of the air quantity of mouth 50, simultaneously as air passes through from the gap between multiple blades 44, so that air distribution is relatively equal
It is even, improve comfort level.
Finally it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than to this reality
With the limitation of novel protected range, although being explained in detail referring to preferred embodiment to the utility model, this field it is general
