  • the blade head Ea can be cleaned effectively and quickly.
  • the cleaning bowl 5 is made of rubber having small elastic modulus and supported in suspension, vibration and sound are reduced even if the blades of the blade head Ea are driven because vibration of the blade head Ea is hardly transmitted to outer shells and the like of the cleaning device 1.
  • the base board 12 receives a lower surface of the cleaning bowl 5 through the heater unit H, and it is accordingly possible to prevent excessive deformation of the cleaning bowl 5.
  • the cleaning liquid in the cleaning bowl 5 goes over the overflow dam 54 and then enters the overflow part 53 to return into the container 7 through the outlet 57 and the connecting pipe 127.
  • the connecting pipe 127 is located just above the filter 89 disposed in the space 7a in the container 7. Therefore, the cleaning liquid with body hair or the like enters the space 7c in a bottom part of the container 7 while flowing through the space 7a along with part of the cleaning liquid without passing through the filter 89.
  • the cleaning liquid without body hair or the like by passing through the filter 89 and the outlets 84 flows to a side of the recess 88 in the space 7b via the inclined plane 86.

  • retention occurs at many places in ribs 85 that are shaped like a grid and disposed on the lower surface of the bottom plate 80 of the filter frame 8. Accordingly, body hair and the like included in the cleaning liquid are deposited and accumulated in the space 7c.
  • the cleaning liquid passing through the space 7c flows through a side of the front part of the container 7 and above the bottom plate 80 of the filter frame 8 to reach the recess 88 facing the opening of the pump P on a side of the back part of the container 7.

  • the space 7c may have a capacity for securing accumulation amount of body hair corresponding to about 10s cleaning operations. If taking the container 7 out from the cleaning device 1 and detaching the filter frame 8 therefrom, a user can wash away the accumulated body hair, and then store new cleaning liquid therein to recover initial cleaning capability.
  • the flange 72 is provided at the upper edge of the container 7 and formed to protrude sideways. It is accordingly possible to smoothly discharge the cleaning liquid (and body hair and the like) with a side of the opening of the container 7 down in order to discard the cleaning liquid in the container 7.
  • the flange 72 is provided for securing hardness for water stop, but the flange 72 is unnecessary in a case where the hardness can be secured by a thickness of a side wall of the container 7.
  • the cleaning liquid in the cleaning part 52 of the cleaning bowl 5 is returned into the container 7 by natural drop from the inlet and outlet port 56 via the connecting pipe 126 and the pump P (a space between the impeller 123 and the pump cover 124).
  • the impeller 123 is soaked in the cleaning liquid in the container 7 and body hair and the like are hardly included in the cleaning liquid in the cleaning part 52 after the cleaning is finished. Therefore, clogging hardly occurs even if the cleaning liquid passes through the pump P. Even if the outlet 57 in the overflow part 53 is clogged during cleaning operation, the cleaning liquid can be prevented from overflowing from the cleaning bowl 5 because another outlet 58 is provided.
  • the motor fan F and a heater of the heater unit H are energized and then the blade head Ea is dried.
