Definitions

the invention relates to a blower, in particular for hair dryers, with a cup-shaped housing cap arranged on the blower housing and engaging over the suction opening and having slits formed in the cap base for the passage of the suction air, in which slits extend radially in the middle section on concentric circular lines and in the edge region.
this object has been achieved in that a large number on an annular surface of the edge region of the housing cap bottom Housing cap center inclined slots are arranged, which are individually in connection with extending in the housing cap peripheral surface axial slots and that the inclination of the slots is directed against the direction of rotation of the fan blade.
the slits are inclined such that the extensions of the central axes thereof extend at a distance from the center of the housing cap.
the slits create a hole pattern for the suction side of the blower with a large passage of air, which leads to a noticeable increase in air performance while maintaining the speed, or requires a reduced speed while maintaining the air performance, which means that the blower is characterized by low noise.
the central axes of the slots form a straight line. But there is also the possibility that the central axes of the slots form arc lines. The curvature of the arc lines can be chosen arbitrarily.
the slits are formed inclined to the left or right in a top view of the cap base and the inclination of the slits is directed against the direction of rotation of the fan blade.
1 denotes a blower for hair drying, the housing 2 of which accommodates an electric motor, a blower wheel and an electric heating register (not shown) in a manner known per se.
the electric motor and the heating register can be applied to a power source in a further known manner by means of switching elements.
3 with a handle is designated, which is hinged to the housing 2.
the blower air can be fed to the blower via a blower housing cap 4 with air passage openings 5 and exits freely through an exhaust air opening in the blower housing 2.
air passage openings 5 4 ⁇ ring-section-shaped slots and in the edge region of the same slots 6 are provided on concentric circular lines of the blower cap base.
the slots 6 are inclined with respect to the center of the housing cap, ie the central axes of the slots 6 form an acute angle ⁇ with radial lines 7.
the inclination of the slits 6 is directed against the direction of rotation of the fan blade.
the slots 6 continue in the housing cap circumferential surface in axial slots 8. It has been found that the inclined slits 6 or slits 6 in connection with the axial slits 8 make a substantial increase in the air output possible at the same speed of the fan blade. It corresponds to the essence of the invention that the slots 6 have either straight central axes (FIG. 2) or, as shown in FIGS. 3 and 4, curved lines to the central axis. The inclination of the slits 6 can run to the left or right. The direction of rotation of the fan blade is opposite to achieve the best air performance.
