Description
Technical field
The invention belongs to fan structure design field, be specifically related to a kind of bladeless fan that can blow a cold wind over.
Background technology
Presently commercially available Safety far without blade profile, including base and the annular air face shield being arranged on base, in base
It is provided with the air draught assembly based on turbine type blower fan;The great advantage of this fan is owing to obviating used by tradition electric fan
Flabellum, from regardless of whether be respectively provided with fabulous safety to adult or child.But this fan there is also following weak point:
In order to avoid huge too fat to move, use the base of small diameter, so limiting the size of turbine type blower fan, enough in order to ensure
Air output, the rotating speed of turbine type blower fan is higher, commonly reaches hundreds of to thousands of turn per second, causes noise very big, and is difficult to eradicate;
Further, since the diameter of turbine type blower fan is the least, although its rotating speed is the highest, but air output still can not be with conventional fan phase
Ratio, airflow effects is the best.
Summary of the invention
It is an object of the invention to provide the bladeless fan that a kind of noise is less, air output is relatively big and can blow a cold wind over.
The technical scheme realizing the object of the invention is: a kind of bladeless fan that can blow a cold wind over, including air draught assembly and air-out
Face shield;It is characterized in that: air outlet face cover is provided with air-out slot;The shape of air-out slot is arc shaped, and air-out slot is at outlet air surface
Ring-type outer wind outlet area and interior wind outlet area it is arranged on cover;Air draught assembly include housing, arrange in the housing there is turbine fan
The turbofan of leaf and setting air channel in the housing;One end of housing is provided with the mesh plate as air inlet of air duct, housing
The other end is provided with duct outlet;Duct outlet connects with air outlet face cover fresh air inlet;It is provided with installation at air outlet face cover fresh air inlet
Portion, housing is provided with one end of duct outlet and is fixed in this installation portion;Housing be provided with the outer wall of one end of duct outlet with
It is provided with sealing ring between the inwall of air outlet face cover installation portion;The inwall of the housing of air draught assembly is provided with the boss of convex, boss
Being provided with centre bore, one end close to turbofan of this centre bore is bellmouth, and this bellmouth is away from one end of turbofan
Aperture less, bigger close to the aperture of one end of turbofan;The shape of the periphery wall of the turbine flabellum of turbofan be with
The circular cone shape that described bellmouth is adaptive;The shell of turbofan is provided with cone on the periphery wall of a side of adjacent turbine flabellum
Shape wall, the external diameter of one end that this tapered wall adjoins turbine flabellum is less, and the external diameter away from one end of turbine flabellum is bigger;Turbine fan
The taper hole that the center of leaf is provided with and this tapered wall is adaptive;Also include cold of multiple electricity, in cold of electricity is arranged on air outlet face cover and
At adjacent duct outlet.
Noise of the present invention is less and air output is bigger;Owing to having cold of electricity, also there is the advantage that can blow a cold wind over.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present invention;
Fig. 2 is a kind of front view of bladeless fan shown in Fig. 1.
Detailed description of the invention
(embodiment 1)
The present embodiment is a kind of bladeless fan, as shown in Fig. 1 and Tu, including air draught assembly 1 and air outlet face cover 2;Air outlet face cover sets
There are fresh air inlet 21, air-guiding aisle 22 and air-out slot 23;Fresh air inlet is arranged on the center, the back side of air outlet face cover, and air-out slot sets
Put the front in air outlet face cover;Air draught assembly includes housing 11, arranges induced-draught fan 12 in the housing, setting wind in the housing
Road 13;One end of housing is provided with the mesh plate 14 as air inlet of air duct, and the other end of housing is provided with duct outlet 15;Air channel
Air outlet connects with air outlet face cover fresh air inlet;Being provided with installation portion 24 at air outlet face cover fresh air inlet, housing is provided with duct outlet
One end is fixed in this installation portion.
Housing is provided with between the outer wall of one end of duct outlet and the inwall of air outlet face cover installation portion and is provided with sealing ring 4.
Described induced-draught fan is turbofan or the fan with flabellum.Used by the present embodiment is to have turbine flabellum 121
Turbofan, but it is also feasible for selecting conventional fan, and can effectively reduce noise.
The present embodiment also includes multiple electricity cold 3;In cold of electricity is arranged on air channel and at adjacent mesh plate;At concrete practice
In, it is possible in being arranged on air outlet face cover by cold for electricity and at adjacent duct outlet.
The basic configuration of air-out slot is arc shaped, leaves spacing between each air-out slot.
Air-out slot is arranged in ring-type outer wind outlet area 25 and interior wind outlet area 26 in air outlet face cover.
Obviously, the above embodiment of the present invention is only for clearly demonstrating example of the present invention, and is not right
The restriction of embodiments of the present invention.For those of ordinary skill in the field, the most also may be used
To make other changes in different forms.Here without also cannot all of embodiment be given exhaustive.And these
Belong to obvious change that the connotation of the present invention extended out or variation still falls within protection scope of the present invention.
