FLOW APPARATUS

An air-flow apparatus for treating air and drying an object has a housing with an interior space, into which the object to be dried can be introduced via an opening of a partially opened lid of the housing, and with a bottom opposite the lid. A pump is connected on its inlet side to the interior space in such a way that, by means of a pumping action of the pump, a negative pressure is generated in the interior space and an air flow directed from the opening into the interior space is generated for drying the object. A flow arrangement has a controllable overpressure generating device, an inflow pipe and at least one nozzle, the overpressure generating device being connected on its outlet side to the interior space via the inflow pipe and the at least one nozzle and being adapted to form an overpressure in the inflow pipe and to generate a second air flow directed into the interior space via the at least one nozzle for drying the object.
