发明名称 Blower
摘要 A blower has a blower tube and a fan unit that conveys an air flow through the blower tube. The fan unit has a fan having a fan axis. The fan conveys the air flow in the direction of the fan axis. The air flow exits the blower tube in an outflow direction at a tube aperture. The handle has on its lower side a grasping point, which in the operating position of the blower, lies on a vertical axis through the blower's center of gravity. The tube aperture has a center axis that is oriented in the outflow direction. So that the forces received by the user at the handle during operation can be made smaller, it is provided for the spacing from the center axis of the tube aperture to the grasping point to be smaller than the spacing from the fan axis to the grasping point.

主权项 1. A blower comprising: a blower tube; a fan unit configured to convey an air flow through said blower tube during operation of the blower; said fan unit including a fan defining a fan axis; said fan being configured to convey said air flow in the direction of said fan axis; said blower tube having a blower tube aperture through which the air flow flows out of said blower tube in a tube outflow direction; a handle having a lower side facing said fan and a grasping point arranged on said lower side; the blower having an operating position and a center of gravity; said grasping point being disposed on a vertical axis through said center of gravity when the blower is in said operating position; said blower tube aperture defining a center axis oriented in said tube outflow direction; said center axis and said grasping point conjointly defining a spacing (a) between each other; said fan axis and said grasping point conjointly defining a spacing (b) between each other; and, said spacing (a) being smaller than said spacing (b).
