摘要 |
The fan wheel (1) of the vacuum cleaner has on the underside (2) a peripheral collar (3) whose diameter is slightly less than that of the fan wheel vanes (5). Said collar enters into a depression (6) on the bottom (7) of the fan housing. A type of labyrinth seal is thus formed together with a wall (8) ahead of the depression (6) so that the underside of the fan wheel, the bearing (17) and the motor shaft (16) are protected from dirt, fibres and the like. <IMAGE> |
