Vacuum / Blower Device |
| 摘要 |
A vacuum/blower device is provided with a drive motor and a fan operatively connected to the drive motor and driven by the drive motor. A switching device is provided that switches the vacuum/blower device from a vacuum operation to a blower operation and from the blower operation to the vacuum operation. A suction pipe with an intake opening is provided, wherein, in the vacuum operation of the vacuum/blower device, a suction air flow is sucked in from the intake opening toward the fan in a first flow direction. The switching device switches a rotational direction of the fan, wherein the fan in the blower operation conveys a blower air flow through the suction pipe in a second flow direction that is oriented from the fan toward the intake opening. |
