Abstract
A turbo fan comprises a fan shell and an axial-flow fan which is fixedly arranged inside the fan shell. The fan shell comprises a front wind deflector and a back wind deflector, the axial-flow fan comprises a motor and fan blades, the front wind deflector corresponds to an air outlet end of the fan blades, and the back wind deflector corresponds to an air inlet end of the fan blades. The turbo fan is characterized in that the front wind deflector is composed of at least a plurality of arc-shaped guide blade plates in a circular array, wherein the arc-shaped guide blade plates comprise at least one arc-shaped surface, an angle exists between the arc-shaped surface and a central shaft of the fan blades, and track of axial-flow wind which a blade wheel blows passes through the arc-shaped surface and carries out a radical motion.
Description
Technical field
The utility model relates to a kind of electric equipment, is meant a kind of vortex flow fan especially.
Background technique
Electric fan is called for short electric fan, is a kind of motoring flabellum rotation that utilizes, and reaches the household electric appliance that make air quicken circulation, is mainly used in cooling and heatstroke-eliminating and ventilating air.Be widely used in family, office, shop, hospital and hotels and other places.
At present; The electric fan kind of selling on the market is a lot, comprises table fan, pedestal fan, but the wind that existing electric fan blows out all is to be parallel to the blower fan axial flow to move; The distance of air-supply is short; And can only blow toward single direction at one time, can only be the ambient air local flow, surrounding atmosphere is circulated on a large scale.
The model utility content
The utility model technical problem underlying to be solved is: traditional electric fan air supply direction is single, can only make the air local flow of air-out direction, to promoting surrounding atmosphere circuit poor effect.
The technological scheme that the utility model adopts is: a kind of vortex flow fan; It comprises casing and is fixedly installed on the axial fan in the casing; Said casing comprises former dome, back air guide sleeve; Said axial fan comprises motor and flabellum, and said former dome correspondence is at the air outlet of said flabellum, and said back air guide sleeve correspondence is at the air intake of said flabellum; It is characterized in that: said former dome is formed by the guide vane annular array of several arcs at least; Wherein, said guide vane comprises the arc shaped surface that has angle between the central shaft of at least one and said flabellum, and the track of the axial flow wind that said impeller is discharged is also producing radial motion through said arc shaped surface.
Be preferable over: said motor is fixedly installed on the air guide sleeve of said back, offers intake opening on the cover of said back air guide sleeve, offers on the side ring surface of said air guide sleeve to add the high wind hole.
Be preferable over: said motor is a direct current generator.
The beneficial effect that the utility model produced is: the axial flow wind through the former dome that adopts turbine-like is discharged axial fan is seen off with the form of eddy current; Utilize the centrifugal force of eddy current to influence air-flow on every side greatly; And then when changing wind direction, impel the wider circulation of ambient air, thereby improve people's quality of life.

Fig. 2 is the partial exploded view of the utility model.
Fig. 3 is the back air guide sleeve schematic representation of the utility model.
Embodiment
Like Fig. 1, shown in 2; A kind of vortex flow fan; It comprises casing 10 and is fixedly installed on the axial fan 20 in the casing 10, and said casing 10 comprises former dome 11, back air guide sleeve 12, and said axial fan 20 comprises motor 21 and flabellum 22; Said former dome 11 correspondences are at the air outlet of said flabellum 22; Said back air guide sleeve 12 correspondences are at the air intake of said flabellum 22, and it is characterized in that: said former dome 11 is formed by guide vane 111 annular arrays of several arcs at least, wherein; Said guide vane 111 comprises the arc shaped surface that has angle between the central shaft of at least one and said flabellum 22, and the track of the axial flow wind that said impeller 22 is discharged is also producing radial motion through said arc shaped surface.
The utility model in the specific implementation, said guide vane 111 arrays of some arcs constitute a turbine, axial flow wind radial deflection under the guiding of said turbine that said flabellum 22 is discharged produces vortex motion then.
Like Fig. 1, shown in 3, said motor 21 is fixedly installed on the air guide sleeve 21 of said back, offers intake opening 121 on the cover of said back air guide sleeve 12, offers on the side ring surface of said air guide sleeve 12 to add high wind hole 122, increases air output by the said high wind hole 122 that adds.
Said motor 21 adopts direct current generators, the noise in the time of can reducing said blower fan 20 runnings, but and power saving.
Claims (3)
1. vortex flow fan; It comprises casing and is fixedly installed on the axial fan in the casing, and said casing comprises former dome, back air guide sleeve, and said axial fan comprises motor and flabellum; Said former dome correspondence is at the air outlet of said flabellum; Said back air guide sleeve correspondence is at the air intake of said flabellum, and it is characterized in that: said former dome is formed by the guide vane annular array of several arcs at least, wherein; Said guide vane comprises the arc shaped surface that has angle between the central shaft of at least one and said flabellum, and the track of the axial flow wind that said impeller is discharged is also producing radial motion through said arc shaped surface.
2. a kind of vortex flow fan as claimed in claim 1 is characterized in that: said motor is fixedly installed on the air guide sleeve of said back, offers intake opening on the cover of said back air guide sleeve, offers on the side ring surface of said air guide sleeve to add the high wind hole.
