<p>The outlet (1) has an air duct (2) divided into a circular outer channel (2.1) and an inner channel (2.2), where the outer channel surrounds the inner channel and runs parallel to the inner channel. Air guiding elements (3.1, 3.2) are attached to the inner and outer channels and arranged on a common symmetry axis (5). The air guiding elements are axis-symmetrically formed with respect to the symmetry axis and/or their rotation axes (4.1, 4.2), where the rotation axes run transverse to the air duct.</p> |
