Description
Technical field
The present invention relates to fan assembly, relate in particular to a kind of no blade fan assembly.
Background technique
Common fan is a blade type, and blade relies on its lift angle in rotary course, forms wind-force forward.This traditional fan, its air-out is interrupted, wind-force pulsation ground impacts and have discomfort on human body.
People utilized the enlarge-effect on continuous air-out principle and coanda surface afterwards, had produced no blade fan, had solved the problems referred to above.On May 6th, 2009 disclosed " fan ", just belong to no blade fan as Chinese patent literature CN101424279A, this disclosure of the Invention a kind of fan assembly that is used to produce air stream.The vaneless fan assembly that is provided comprises nozzle and the member that is used to produce by the air-flow of nozzle.Nozzle comprises the inner passage, be used to receive from the relief opening of the air-flow of inner passage and the coanda surface of next-door neighbour's relief opening location, and relief opening is arranged to steering flow and is flow through the coanda surface.This fan provides and need not the device that blade fan just can produce air-flow and cooling air flow, promptly produces air-flow with the on-bladed fan.
How to limit between the aforementioned patent document unexposed relief opening apparent surface of fan openly, in fact, if it is unqualified between the relief opening apparent surface, be difficult for forming the relief opening that size is determined in making on the one hand, on the other hand, the wind bundle is irregular, and in the tuyere of circular ring type, the wind bundle that penetrates has spiral effect, and this is to use in the process undesirable.The disclosed fan of Chinese patent literature CN101749289A has solved foregoing problems to a certain extent.The document discloses a kind of fan component that is used to form air-flow, and this fan component comprises that being installed in base portion takes up nozzle on the device, and this base portion takes up device and is used to form air-flow through this nozzle.This nozzle comprises inner passage and the mouth that is used to receive from the air-flow of base portion, and wherein air communication is crossed mouth dress portion and is launched, and this mouth is limited and be used to separate the apparent surface's of nozzle spacing means by the apparent surface of nozzle.Nozzle generally perpendicularly extends to limit an opening around an axis, is dragged from the air-flow of described mouth emission from the fan component air outside and inhales by described opening.Nozzle extends limiting described opening around an axis, and wherein said spacing means comprises a plurality of spacer elements around the angled interval of described axis, preferably around described axis equal angles ground at interval.The spacing means of this record objectively plays the effect of water conservancy diversion, makes the wind bundle be tending towards uniform distribution in tuyere.Yet the flow velocity of the air that flows in the tuyere is not wait, and the flow velocity of the wind bundle of close air inlet end is all greater than the relative the other end.Adopt the spacer element of putting down in writing in the aforementioned patent document around interval, described axis equal angles ground, obviously can not make exhaust port even wind in its (extension) length, can not drive the opening air-out effectively on the one hand, the inhomogeneous of air quantity can the user have discomfort on the other hand.
