Summary: | PROBLEM TO BE SOLVED: To provide an arrangement with outer and inner walls which prevents fluid from passing through and recirculating within a space between the outer and inner walls.SOLUTION: A hand held appliance is disclosed. The appliance comprises an outer wall, an inner wall, a fluid flow path extending within the inner wall from a fluid inlet to a fluid outlet, a fan unit disposed within the inner wall for drawing fluid in through the fluid inlet, and a seal disposed between the outer wall and the inner wall. Fluid in the fluid flow path flows from the fluid inlet to an upstream end of the fan unit, through the fan unit to a downstream end of the fan unit and to the fluid outlet. The seal may be provided at downstream of the fluid inlet. The seal may be provided at downstream of the fan unit. The outer wall may comprise a handle of the appliance. The seal may comprise an O-ring, a lip seal or any overmolded seal.SELECTED DRAWING: Figure 4a
【課題】外側壁及び内側壁を有する構成において、流体が外側壁と内側壁との間の空間を通過してこの空間内で再循環するのを防止すること。【解決手段】手持ち式電気器具が開示され、電気器具は、外側壁と、内側壁と、内側壁内にて流体入口への流体出口に延びる流体流路と、内側壁内に配置され、流体入口を通って流体を引き込むためのファンユニットと、外側壁と内側壁との間に配置されたシールとを備える。流体流路中の流体は、流体入口からファンユニットの上流端、ファンユニットを通って、ファンユニットの下流端、及び流体出口に流れる。シールは、流体入口の下流に設けることができる。シールは、ファンユニットの下流に設けることができる。外側壁は、電気器具のハンドルを備えることができる。シールは、Oリング、リップシール、又は任意のオーバモールドシールを備えることができる。【選択図】図4a |
