风扇
摘要：
一种用于形成气流的无叶片风扇组件（100），该风扇组件包括安装在基部（16）承装装置上的喷嘴，该基部承装装置用于形成经过该喷嘴（1）的气流。该喷嘴包括用于接收来自基部（16）的气流的内部通道（10）和嘴部（12），其中气流通过嘴装部（12）被发射。喷嘴（1）绕一轴线延伸，以限定一开口（2），来自风扇组件（100）外部的空气被从所述嘴部（12）发射的气流拽吸通过所述开口。喷嘴（1）包括一表面，在该表面上方所述嘴部（12）被设置以引导气流。该表面包括扩散部分（46）和引导部分（48），该扩散部分呈锥形地远离所述轴线，该引导部分在所述扩散部分（46）下游并与之成角度。
摘要（英）：

A fan assembly 100 comprises a nozzle 1 mounted on a base 16 which houses means for creating an air flow through the nozzle 1. The nozzle 1 comprises an interior passage 10 which receives air flow from the base 16, and a mouth 12 through which the air flow is emitted. The nozzle 1 extends substantially about an axis x-x to define an opening through which air from outside the fan assembly is drawn by the air flow emitted from the mouth 12. The nozzle 1 further comprises a surface over which the mouth 12 is arranged to direct the air flow. The surface comprises a diffuser portion 46 tapering away from the axis x-x, and a guide portion 48 downstream from the diffuser portion 46 and angled thereto. The nozzle 1 may comprise a substantially annular or circular loop. The means to create an air flow may be an impeller 30 driven by a motor 22.
