Abstract
Disclosed is a wide-angle air-supply fan, each single vane of a fan wheel of the fan comprises two or three portions of an axial-flow fan blade portion (1), a radial-flow fan blade portion (3) and an oblique-flow fan blade portion (2) ( a transition portion from the axial-flow fan blade to the radial-flow fan blade), or the fan wheel includes two or three blades of the axial-flow flan blade, the radial-flow fan blade and the oblique-flow fan blade. The utility model can enlarge the air-supply angle of the fan without adding auxiliary mechanisms to obtain stable blowing flow in the air-supply range, and further, if the utility model is used as a ventilator, ventilating effect can be optimized well.
Description
Affiliated technical field
The utility model relates to a kind of fan, especially the stable wide-angle Air Blast fan of air quantity.
Background technique
At present, general family expenses fan all is an axial fan.In order to enlarge the ventilation effect in wind direction or certain space of homogenizing, increase oscillating mechanism or increase the rotation guide disc to fan usually.So not only increased the cost and the rate of fault of fan, and air quantity is very unstable, dynamic in its blowing range.
Summary of the invention
The utility model provides a kind of fan, and this fan enlarges wind direction by changing the fan blade shape under the prerequisite that does not increase subsidiary body.
The technological scheme that the utility model adopted is: electric fan is made (radially) sickleshaped, made to comprise axial flow flabellum part, runoff flabellum part and oblique flow flabellum part (transition portion from the axial flow flabellum to the runoff flabellum) three parts or two-part wherein on the single flabellum; Or its impeller is provided with axial flow flabellum, runoff flabellum and three kinds of flabellums of oblique flow flabellum or two kinds of flabellums wherein.
The beneficial effects of the utility model are: enlarge the wind direction of fan under the prerequisite that does not increase subsidiary body, reduced the cost and the rate of fault of fan simultaneously; And air quantity is stable in its blowing range, if ventilation fan can be optimized ventilation effect well.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the radial view of an embodiment's of the utility model impeller.
Fig. 2 is the plan view of Fig. 1.
(1) is the axial flow flabellum part of flabellum among the figure, and (3) are the runoff flabellum parts of flabellum among the figure, and (2) are the oblique flow flabellum parts of flabellum among the figure.
The air-supply wind direction of arrow in order to illustrate that wide-angle of the present utility model is blown among Fig. 1.
Fig. 3 is the 3-D view of the impeller of present embodiment.
Embodiment
As shown in Figure 1 and Figure 2, existing axial flow flabellum part (1) has runoff flabellum part (3) and oblique flow flabellum part (2) again on the single flabellum on this impeller of present embodiment.At present do not adopt this impeller just can implement the utility model with the fan or the ventilation fan of oscillating mechanism or rotation guide disc.When fan work, the axial flow flabellum of four flabellums on impeller part (1) is air-supply axially; The runoff flabellum part (3) of four flabellums on the impeller is radially blown; The oblique flow flabellum of four flabellums on impeller part (2) is to from axially to the radially tilted direction of transition air-supply gradually.
Claims (1)
1. a wide-angle Air Blast fan utilizes the flabellum air-supply on the rotation impeller, it is characterized in that: axial flow flabellum part, runoff flabellum part and oblique flow flabellum part three parts or two-part are wherein arranged on its single flabellum; Or axial flow flabellum, runoff flabellum and three kinds of flabellums of oblique flow flabellum or two kinds of flabellums are wherein arranged on its impeller.
