Abstract
The utility model relates to a fan whose air source is externally arranged, which comprises fan leaves of a fan, a fan protecting cover and a fan supporting stand. The utility model is characterized in that one end of a wind pipe is connected with an outer blowing machine, and a pipe orifice on the other end is aslant inserted in the protecting cover from the outer of the fan, and directly faces to the windward side of the fan leaves of the fan. The fan whose air source is externally arranged makes people enjoy comfortable cool air through leading in fresh air from external world to be an air source of the fan by the blowing machine and pushing the fan leaves of the fan to rotate and dispel wind.
Description
Technical field
The utility model belongs to wind regime external fan art.
Background technique
Traditional electric fan all is directly to drive the flabellum rotation by motor, because flabellum itself has several angle, when flabellum rotated, the air of flabellum back was sent through the place ahead that the flabellum that rotates flows to flabellum, formed wind and lowered the temperature to people.The deficiency of this electric fan is that the air that forms wind can only flow in indoor circulation, can not make full use of the quality that outdoor fresh air improves indoor air.Though and outdoor fresh air can be blown into indoor with blower, but conventional blower air outlet tube mouth does not generally have other facilities to stop, air-out is concentrated, wind can not loose, cause people to feel can't stand in air outlet tube mouth the place ahead, and, do not have the effect of cooling not at the imperceptible wind of the people in air outlet tube mouth dead ahead.
Summary of the invention
The technical problems to be solved in the utility model provide a kind of can be from the wind regime external fan of outdoor introducing fresh air for improving IAQ.
The utility model solves the problems of the technologies described above with following technological scheme: an end of airduct is connected with outdoor blower, and the mouth of pipe of the other end oblique cutting outside fan is gone into the windward side of directly facing electric fan in the safety cover.
Wind regime external fan of the present utility model, by blower from outdoor introducing fresh air as the wind regime of fan and promote the flabellum rotation of fan, the wind that looses, make people enjoy comfortable cool breeze.
Description of drawings
Fig. 1 is the structural representation of the utility model wind regime external fan.
Embodiment
Wind regime external fan of the present utility model, blower 5 is installed in outdoor, and fan is installed in indoor, has airduct 7 to connect between fan and the blower; The end that airduct is connected with blower has adpting flange 4, and the mouth of pipe 6 oblique cutting outside fan of the other end is gone into the windward side of directly facing electric fan 2 in the fan safety cover 1.The break-make of valve 3 with control wind is installed on airduct.
When needing the fan blowing, start blower earlier, outdoor fresh air promptly can directly blow on the windward side of fans by airduct after opening valve from the mouth of pipe, fan rotates because of the windward side is subjected to wind-force, broken up back lee face by the air of airduct by fans and blow out, become the soft wind that makes us feeling comfortably cool from fan.
Claims (1)
1. a wind regime external fan has electric fan, fan guard and blower tray, and an end that it is characterized in that airduct is connected with outdoor blower, and the mouth of pipe of the other end oblique cutting outside fan is gone in the safety cover directly the windward side in the face of electric fan.
