Definitions

  • a screw hole 28 extending in the rotation axis direction is formed at the end of the support portion 26 of the resin housing 208.
  • a fixing screw 218 can be screwed into the screw hole 28, and the guide blade 205 is fixedly installed on the resin housing 208 by screwing the fixing screw 218.
  • a cylindrical convex portion 17 is provided on the outer periphery of the through hole 16 on the return guide 205b side.
  • the bearing cover 215 is provided with the cooling fins 27 at the position of the opening 34 of the housing 208.
  • the cooling fins 27 are not disposed on the bridge 30 portion of the housing 208.
  • the bridge 30 is provided with a rib 26c instead of the cooling fin 27.
  • the rib 26 c is connected to the bridge 30 and the substantially double cylindrical support portion 26 (26 a, 26 b) of the support portion of the housing 208, and has an effect of increasing the rigidity of the housing 208.
  • the resin material melted by welding does not protrude into the flow path of the centrifugal impeller 203, and the airtightness in the flow path can be reliably obtained. Thereby, the efficiency of the electric blower 200 can be improved reliably.
  • the output of the electric vacuum cleaner can be improved. Further, by improving the efficiency of the electric blower 200, the input of the electric blower 200 can be lowered when the same output is obtained, and the operation time can be extended in the rechargeable cleaner using a battery as a drive source. .
