| 摘要 |
The invention relates to an air outlet having at least one air outlet opening which is assigned an air chamber continuously supplied with preferably treated supply air, and having a pressure-increasing device which produces in the air chamber preferably pulse-like, in particular periodic air pressure increases such that appropriate quantities of air are ejected in each case as vortices along a vortex path from the air outlet opening. Provision is made for the air chamber (2) to be assigned at least one pressure frequency source (30) for generating air pressure vibrations. <IMAGE> |
