Description
Technical field
Patent of the present invention belongs to bladeless fan technical field, be specifically related to a kind of double-inside-impellfan without fan-leaf fan.
Background technology
Bladeless fan is not because impeller exposes, there is safety good, advantage easy to clean, so being looked at by the eyeball of people, but existing bladeless fan is all used an interior impeller to produce wind and is delivered to a closed annular nozzle, it is that wind-force is uneven that [such as number of patent application: fan disclosed in 200810177844.8] interior impeller produces the main disadvantages of the bladeless fan existence that wind delivers to a closed annular nozzle, encloses wind-force near closed annular nozzle one big, and little at closed annular nozzle middle part wind-force；Additionally, the motor of existing bladeless fan is all to enclose following vertical working in annular Guan Bi, and the wind that interior impeller produces upwards blows, and arriving closed annular nozzle needs more than 50 ° to turn, prolonging Coanda surface from the ejection of closed annular nozzle again and need again the turning through more than 120 °, wind-force has and substantially weakens；And if motor can transfer laterally work to, [such as number of patent application 201110256873.5] then from this laterally in wind of impeller blowout need how just to arrive closed annular nozzle through the turning of 90 °, so wind-force has and becomes apparent from weakening, power attenuation is bigger.Necessary innovation.
Summary of the invention
The invention aims to provide a kind of single-motor double load, double air inlet, the double-inside-impellfan fan of Crossed Circle air outlet, motor is uprightly changed into intermediate lateral work in ring below closed circuit nozzle by it, air-flow is without prolonging the turning on more than 120 ° of Coanda surface, directly it is linked with big annular air outlet by top, several ajutage top, annular air mouth little with center air-out simultaneously；Large and small two annular air mouths are associated with again large and small two air-flow attached wall circles, and the direction of air intake, air-out is consistent, thus reduce loss, increase air total flow in circle, it is provided that the wind of the most comfortable multiplication.
Above-mentioned goal of the invention is achieved through the following technical solutions: a kind of double-inside-impellfan fan, it includes blower tray, horizontal motor on blower tray, motor shaft on motor, it is characterized by the rear end of motor shaft equipped with impeller in first, the front end of motor shaft is equipped with impeller in second, in first, impeller periphery is provided with the first cover body, in second, impeller periphery is provided with the second cover body, the first fresh air inlet and more than one ajutage it is shaped with on the first described cover body, the end of ajutage is provided with big annular air outlet, first fresh air inlet, impeller in first, ajutage, big annular air outlet interconnects and forms an air intake, produce wind, air-supply is to the passage of air-out；Being shaped with the second fresh air inlet on second cover body, the second cover front end is shaped with center little annular air mouth, the second fresh air inlet, impeller in second, center little annular air mouth interconnect composition air intake, produce wind, the another passage of air-supply to air-out.
As preferably, described outer big annular air outlet being shaped with the big attached wall circle of air-flow, circle wall is straight forward, guides air-flow enclosing included wall forward；Being provided with air-flow attached wall outlet housing in the little annular air mouth of described center to stretch out, cover wall becomes circular cone arc, guides the air-flow attached wall of thimble placed in the middle forward.
As preferably, its big annular air outlet, the radial spacing of center little annular air mouth select between 5 to 30 millimeters according to corresponding wind speed.
As preferably, the ring heart of described big annular air outlet annular air little with described center mouth two ring overlaps, ring heart position at motor.
As preferably, described air-flow attached wall outlet housing end is provided with air-out void pattern, annular air mouth little with center air-out simultaneously；Being provided with loop isolation stall between the first cover body and the second cover body on motor, motor was both fixed on blower tray by it, front and back's air intake, product wind, two channel separation of air-supply to air-out was opened again.
It is safe, energy-conservation, clean and tidy that patent of the present invention not only has existing bladeless fan, the advantage that noise is low, and two interior impellers of the axle two ends of motor configuration, make motor load more balance and all claim；And it is provided with big annular air outlet, center little annular air mouth, therefore the wind of its blowout is uniform, makes people have a kind of comfort.It addition, the wind direction of big annular air outlet, the blowout of center little annular air mouth is consistent, thus provide the total air flow evenly doubled, because only with a motor, so low cost, wind effect height of output.
