The another kind of technological scheme that the utility model adopts is: be used to produce the on-bladed fan of air stream, it comprises: pedestal is provided with the member that is used to produce high pressure draught in described pedestal; Outlet frame with closed circuit, described outlet frame is installed on the described pedestal, described outlet frame comprises inner passage and the relief opening that is used to receive from the high pressure draught of described pedestal, high pressure draught is injected by described relief opening, the closed circuit of described outlet frame limits opening, the air-flow suction that described fan assembly air outside is sprayed from described relief opening by described opening; It is characterized in that described outlet frame has a plurality of closed circuits, a plurality of closed circuits of described outlet frame limit a plurality of openings, and each opening has similar shapes.
The number of the closed circuit that described outlet frame adopts is many more, provides large-area speed uniform airflow easily more.Consider the production technology problem, the number of its closed circuit is usually between 2 to 30, be its accordingly by the number of the opening that a plurality of closed circuit limited of described outlet frame usually between 2 to 30, the number of preferred opening is between 2 to 10.
It may be noted that especially, because it is the structure of a plurality of openings that described outlet frame adopts a plurality of closed circuits, aspirated effectively by the air-flow that sprays from described relief opening by described opening in order to make described fan assembly air outside, on one section public loop between two adjacent openings, need to be provided with two row's relief openings, several rows of gas port wherein is near one of them opening, and wherein another arranged close another opening wherein of relief opening.
Help strengthening air outside and pass through described opening by the air-flow pumping function that sprays from described relief opening, described outlet frame comprises the coanda surface that is provided with near described relief opening.
About the shape of described opening, can be circular, oval, round rectangle, also can be the part annular, can also be other shape.
Described relief opening can be the hole shape relief opening, also can be slot-shaped relief opening, can also be the relief opening of other shape, preferably the continuous basically slot-shaped relief opening that is provided with along the loop wall of described outlet frame.
About term " high pressure draught " be meant that air pressure is higher than the air-flow of fan around atmospheric pressure.
About term " on-bladed " is to be used for describing that air-flow discharges forward from the fan assembly or ejection and do not need to use impeller assembly.By this definition, vaneless fan assembly can be counted as has output face or the launch site that does not have the blade or the wing, and air-flow is along roughly therefrom discharging or launch towards user's direction.
The on-bladed fan can provide main air to originate by multiple source apparatus or generating means and produce high pressure draught, for example pump, generator, motor or comprise engine rotor and other fluid delivery systems of rotating equipment such as impeller blade.The air quantity that produces by motor makes passes inner passage arrival outlet frame the environment of air draught from room or fan assembly outside, sprays from relief opening then.Therefore, do not lie in the required parts of fan secondary function such as extending to power source and component about the illustrative purposes of term " on-bladed ", such as motor.The example of fan secondary function comprises the swing of illumination, adjusting and fan.
The described member that is used to produce high pressure draught can comprise also can comprise dc brushless motor and mixed flow impeller by motor-driven impeller.
The utlity model has following good effect:
Because the outlet frame of the utility model device adopts a plurality of closed circuits to be the structure of a plurality of openings and all to be provided with relief opening on the loop wall of each opening, significantly improved on the whole the fan assembly air outside by opening by the ability that air-flow aspirated of spraying from relief opening, make fan assembly that large-area speed uniform airflow can be provided, make the user can experience comfortable nice and cool effect on a large scale; In addition, because each opening has similar shapes, be easy to make up and obtain attractive in appearance, the welcome fan assembly of different shape.
