Description
Technical field
The present invention relates to a kind of fan assembly.
Background technique
The Chinese patent application that on May 6th, 2009, publication number was CN 101424278A (application number: 200810177843.3) disclose a kind of no blade fan that is used to produce air stream, this kind fan comprises: nozzle and the member that is used to produce by the high pressure draught of described nozzle, its nozzle has inner passage and the relief opening that is used to receive from the air-flow of pedestal, it is injected that air communication is crossed described relief opening, nozzle extends orthogonally basically about axis and limits opening, described relief opening is provided with around the nozzle wall of described opening, and described fan air outside is aspirated by the air-flow that sprays from described relief opening by described opening.When this kind fan was worked near objects such as walls, described fan air outside can not effectively enter described opening to be aspirated from the air-flow that relief opening sprayed, and its air output significantly reduces, and its use is very restricted.
Summary of the invention
The present invention aims to provide a kind of new fan assembly to overcome above-mentioned defective of the prior art.The objective of the invention is to provide a kind of no flabellum fan assembly that can use near objects such as walls; Another purpose of the present invention provides a kind of no flabellum fan assembly of compact structure.
In order to achieve the above object, the technical solution used in the present invention is: the no flabellum fan assembly that is used to produce air stream, described fan assembly comprises nozzle and the member that is used to produce by the high pressure draught of described nozzle, it is characterized in that, described nozzle comprises container and is arranged on the relief opening on the outer wall around the described container, described high pressure draught is injected by described relief opening, described fan assembly air outside is aspirated by the air-flow that described relief opening sprayed, and described member has at least part to be arranged in described container.
Described high pressure draught is meant that air pressure is higher than the air-flow of described fan assembly ambient air pressure.
In order to make described fan assembly compactness, described member major part is arranged in described container, and preferably, described member all is arranged in described container.
Described member comprises motor and by described motor-driven impeller; Described motor can be an inner rotor motor, also can be external rotor electric machine; Described motor can be an AC induction motor, and dc brushless motor can also be other motor.
Described container can adopt multiple shape, can be roughly cylindrically, can partly be cylindrical also, can also other shape; Described container can be about described axis symmetry.
The Way out of described relief opening and the angle between the axis are usually between 0 degree is spent to 30, preferably between 0 degree is spent to 20.
In order to improve air output, can be provided with at least one opening at the middle part of described container, and on around the inwall of described opening, also be provided with relief opening.
Described relief opening can adopt multiple shape, can be general toroidal, can be circular, also can be part circular, can also be other shape.
Described nozzle can also comprise the fluid director that is positioned at described relief opening outlet the place ahead, the frictional loss that this helps improving the suction effect of air-flow and reduces air-flow.Described nozzle can be communicated with the described member that is positioned at another place by pipeline, preferably use flexible pipe to be communicated with, so that the high pressure draught that described member produced can send described nozzle to by described pipeline easily, for example described member is in outdoor, described nozzle is positioned at indoor, can use flexible pipe that described member is communicated with described nozzle easily.
In order to reduce the noise of described fan assembly, can on the wall of described internal tank, quieter material be set, also can the sound insulation chamber be set at the intake grill place of described container.
Attractive in appearance or expand its use in order to improve it, can decoration or daily apparatus be set in described container the place ahead central region, as draw, animal toy, mirror etc.
The present invention has following good effect:
Because the relief opening of apparatus of the present invention is set on the outer wall all around of described container, be surprised to find, the air-flow that relief opening sprayed around its container on the outer wall has the ability of significant suction surrounding atmosphere, than being that the ability that relief opening aspirated on the inwall is eager to excel on the cavity wall that is arranged at a toroidal container inside in the prior art; In addition, no matter apparatus of the present invention can both effectively aspirate described fan assembly air outside whether near objects such as walls, have expanded using scope greatly; Also have, because described member is set in the described container, the structure of its whole device is very compact, and the loss noise low and that cause of its high pressure draught transmission is also low, and has effect attractive in appearance.
