Definitions

  • Such a compressed air blowing device is known from DE-OS 36 00 147. In this case, however, it has been found to be disadvantageous that the cold air nozzle can only be operated in a limited temperature range and that it is difficult to adapt to other temperature ranges. Another disadvantage of this known compressed air blowing device is that with larger air throughputs there is considerable noise, which is perceived as annoying when the compressed air blowing device is used.
  • the object of the invention is to improve the compressed air blowing device of the type mentioned in such a way that operation over a larger cold air temperature range with reduced noise development is also possible with larger air throughputs, with ease of use being able to vary the usability.
  • the object is achieved in that the swirl chamber is designed as a flange disc resting on the cold air nozzle with a central opening, on one side of which a pipe socket for holding the flange disc and on the other side an outer circumferential edge web of a central recess is arranged in which are formed tangentially into the recess of the edge web serving as a swirl chamber interior, that the opening of the nozzle body of the cold air nozzle is designed as a diffuser and that the cold air nozzle and the warm air nozzle are detachably connected to a silencer.
  • the effect of the compressed air blowing device can be determined by rotating the hot air nozzle acting as a throttle.
  • the compressed air blowing device acts like a conventional compressed air blowing device. Only when the hot air nozzle is opened does the temperature of the air emerging from the cold air nozzle drop. Once the exact throttle position has been determined, it can be used again and again at constant compressed air pressure. It is possible to achieve a temperature reduction of approx. 45 ° C. and more compared to the temperature of the compressed air, the temperature of the air emerging from the hot air nozzle being increased only slightly.
