Description
Technical field
The present invention relates to air conditioner end equipment field, especially a kind of rotary pulse is vortexed air supply device.
Background technique
It is that a kind of air is distributed and set for blow and the end-equipment of return air that central air conditioner air inlet, which is in central air conditioner system,
Standby, it is directly related to the distribution of indoor air temperature, humidity etc..
Traditional air port has only served the effect to indoor conveying cooling capacity in air-conditioning system, lacks the effect of class nature wind pulse
Fruit, it is difficult to achieve the effect that natural-wind-imitating.
Summary of the invention
The purpose of the present invention is overcome the deficiencies in the prior art, and provide a kind of rotary pulse vortex air supply device, its energy
Rotary pulse vortex is generated to promote indoor thermal comfort, builds the air-out effect of natural-wind-imitating.
The technical scheme is that rotary pulse be vortexed air supply device, including air funnel, mesh enclosure end cap, central axis and
Impeller;Air funnel is the cylinder of both ends open, and one end is air intake, and the other end is outlet air end;The quantity of mesh enclosure end cap is two
A, two mesh enclosure end caps are separately mounted at the both ends open of air funnel;Central axis is located in air-supply tube inner chamber, both ends difference
It is connected at the center of two mesh enclosure end caps;Impeller includes central tube and annular is evenly distributed with and multi-disc of the solid welding on the drum outer wall of center
Airfoil fan, impeller pass through central tube movable set on center shaft, and are located in air-supply tube inner chamber, and determined in the axial direction
Position.
The further technical solution of the present invention is: one side surface of airfoil fan is outer convex globoidal, another side surface is indent
Cambered surface, airfoil fan front end is towards air funnel air intake, and towards air funnel outlet air end, airfoil fan is thick to the back-end from front end for rear end
Degree gradually reduces, and the outer convex globoidal and inner concave arc surface of airfoil fan are seamlessly transitted in airfoil fan front end by cambered surface, in aerofoil profile
The rear end of blade crosses to form a rib.
Further technical solution is the present invention: the quantity of the airfoil fan of impeller is 4.
The invention has the following advantages over the prior art:
1, when air-flow passes through airfoil fan, pressure difference is formed in outer convex globoidal and inner concave arc surface, and then drive wheel rotation, separately
Outside, due to the wing-shaped structure of airfoil fan, the tail portion that air-flow reaches airfoil fan can generate pulsed eddy, to make flow shedding
A kind of rotary pulse vortex is formed after airfoil fan, is achieved the effect that natural-wind-imitating, is promoted indoor thermal comfort.
2, impeller is the component that can be individually replaced, can be by replacing different airfoil fan size and not in practical application
The impeller of same airfoil fan number to achieve the effect that regulate and control the fluctuating scale and frequency spectrum of rotary pulse vortex, and then meets
To the fluctuating scale of wind and spectrum requirement under varying environment.
Below in conjunction with figure, the invention will be further described with embodiment.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention;
Fig. 2 is explosive view of the invention;
Fig. 3 is the structural schematic diagram of impeller;
Illustrate: the air funnel in Fig. 2 is not shown.
Specific embodiment
Embodiment 1:
As shown in Figure 1-3, rotary pulse is vortexed air supply device, including air funnel 1, mesh enclosure end cap 2, central axis 3 and impeller 4.
Air funnel 1 is the cylinder of both ends open, and one end is air intake, and the other end is outlet air end.
The quantity of mesh enclosure end cap 2 is two, and two mesh enclosure end caps 2 are separately mounted at the both ends open of air funnel 1.
Central axis 3 is located in 1 inner cavity of air funnel, and both ends are connected at the center of two mesh enclosure end caps 2.
Impeller 4 includes central tube 41 and annular is evenly distributed with and multi-disc airfoil fan 42 of the solid welding on 41 outer wall of central tube, the wing
42 1 side surface of type blade is outer convex globoidal, another side surface is inner concave arc surface, and 42 front end of airfoil fan is entered the wind towards air funnel 1
End, rear end is towards 1 outlet air end of air funnel, and airfoil fan 42 is from front end rear end tapered thickness, the evagination of airfoil fan 42
Cambered surface and inner concave arc surface are seamlessly transitted in 42 front end of airfoil fan by cambered surface, cross to form one in the rear end of airfoil fan 42
Rib.Impeller 4 (is equipped with bearing 5, the two is logical on central axis 3 by 41 movable set of central tube between central tube 41 and central axis 3
Cross bearing 5 and realize relative rotation), and be located in 41 inner cavity of air funnel, and positioned in the axial direction.
It is preferred that the quantity of the airfoil fan 42 of impeller 4 is 4.
It is preferred that the outer convex globoidal of the airfoil fan 42 of impeller 4 is opposite with the inner concave arc surface of adjacent aerofoil blade 42, aerofoil profile leaf

It is preferred that the plane projected shape of the airfoil fan 42 of impeller 4 is right-angled trapezium (referring to Fig. 2).
It sketches use of the invention: air funnel 1 being mounted on the air outlet of air outlet device (such as central air-conditioning), outlet air
The air-flow of equipment discharge is entered in 1 inner cavity of air funnel by 1 air intake of air funnel, and is flowed to 1 outlet air end of air funnel.Air-flow is logical
When crossing the airfoil fan 42 of impeller 4, due to the lift effect of airfoil fan 42, pressure is formed in outer convex globoidal and inner concave arc surface
Difference, and then impeller 4 is driven to rotate.In addition, air-flow reaches the tail portion meeting of airfoil fan 42 due to the wing-shaped structure of airfoil fan 42
Generate pulsed eddy.Rotary pulse vortex can be formed under the two collective effect, after flow shedding airfoil fan 42, reached and imitated certainly
The air-out effect of right wind.
