Description

A kind of safe electric fan that can freeze
Technical field
The invention belongs to fan structure design field, be specifically related to a kind of safe electric fan that can freeze.
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 safe electric fan that can freeze that a kind of noise is less and air output is bigger.
The technical scheme realizing the object of the invention is: a kind of can the safe electric fan of refrigeration, including air draught assembly and going out Wind face shield；It is characterized in that: also include cold of multiple electricity；Air outlet face cover is provided with fresh air inlet, air-guiding aisle, air-out slot and installation Portion；Fresh air inlet is arranged on the back side of air outlet face cover, and air-out slot is arranged on the front of air outlet face cover, and installation portion is arranged on outlet air surface Cover center, the back side；Air draught assembly includes housing, arranges induced-draught fan in the housing, setting air channel in the housing；Housing One end is provided with the mesh plate as air inlet of air duct, and the other end of housing is provided with duct outlet；Housing is provided with duct outlet One end be fixed in installation portion, duct outlet connects with air outlet face cover fresh air inlet；Electricity cold be arranged on air channel in and adjoin At mesh plate；The inwall of the housing of air draught assembly is provided with the boss of convex, and boss is provided with centre bore, and this centre bore is away from air draught The aperture of one end of machine is less, and this centre bore is bigger close to the aperture of one end of induced-draught fan；Described induced-draught fan is to have turbine fan The turbofan of leaf, the shape of the periphery wall of the turbine flabellum of turbofan is adaptive with described centre bore；Air-out slot is going out Ring-type outer wind outlet area and interior wind outlet area it is arranged on wind face shield.
The present invention is arranged on the center, the back side of air outlet face cover air draught assembly, due to air outlet face cover and tradition bladeless fan Base compare, diameter wants big several times, so the present invention can select the induced-draught fan that flabellum is bigger, it is not necessary to the highest rotating speed is i.e. Good airflow effects can be realized；Thus there is the advantage that noise is less and air output is bigger.The present invention and tradition bladeless fan Equally, flabellum is built-in, and outside be can't see, and is also air draught at the mesh plate that aperture is the least, air-out from the least air-out slot, The finger of child is inserted not enter, so also having preferable safety.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present invention；
Fig. 2 is a kind of front view of safe electric fan shown in Fig. 1.
Detailed description of the invention
(embodiment 1)
The present embodiment is a kind of safe electric fan, as shown in Fig. 1 and Tu, including air draught assembly 1 and air outlet face cover 2；Outlet air surface It is covered with 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 is narrow Hole is arranged on the front of air outlet face cover；Air draught assembly includes housing 11, arranges induced-draught fan 12 in the housing, setting in the housing Air channel 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； Duct 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 air channel air-out One end of mouth 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.
