ABSTRACT:
A discharge nozzle has directional blades which can be swivelled about a swivel axis running parallel to the discharge-side front edge of a housing. The blades are swivelled by means of a coupling part, providing the directional blades with a common orientation. Diffused air flow through the discharge nozzle is selectively provided by diffusing insert blade segments which are insertable between the directional blades. The diffusing blades are part of a rigid diffusing grid, which is at least partially insertable from the back side of the directional blades between these blades and which is guided in a sliding manner in the nozzle housing by means of a rotary control button having a spiral guideway.
