  • a sensor 14 for flow measurement In the supply air duct 2 is located in this embodiment behind the heater 4, a sensor 14 for flow measurement. With this, the evaluation of a total volume flow V of the process air is determined by an evaluation unit 13 and a comparison of this with a limiting volume flow V lim . Assuming that, in the event of contamination of the heat exchanger 5, the volume flow of the process air drops, the cleaning process is triggered by the evaluation unit 13 if the total volume flow V falls below the limit volume flow V lim . It should be noted that the placement of the sensor 14 designed as a volumetric flow sensor 14 in the process air circuit is largely uncritical. However, the positioning behind the heater 4 is preferred because there the process air flow is largely free of lint and the like possibly debilitating loads and thus long-term reliable measurement can be expected.
  • a sensor 14 placed at the designated point for temperature measurement is also considered.
  • the evaluation unit 13 determines a temperature gradient ⁇ T of the process air and compares it with a limit temperature gradient ⁇ T lim . Assuming that in case of contamination of the heat exchanger 5 with decreasing volume flow of the process air whose temperature rises behind the heater 4, the cleaning operation is triggered by the evaluation unit 13 when the temperature gradient .DELTA.T exceeds the limit temperature gradient .DELTA.T lim .
  • a counter 11 for the number of drying processes carried out, a clock 12 and a correspondingly programmed evaluation unit 13 are additionally present as a means for determining a cleaning requirement of the air-to-air heat exchanger 5. These are either part of the control device 10 of the condensation dryer 1 or assigned to it.
  • the cleaning requirement is determined by the control device 10 and the evaluation unit 13 at the in Fig. 1 a cleaning process triggered, in which the air-air heat exchanger 5 by means of a in a reservoir 19 existing rinsing liquid 29 is cleaned.
  • the rinsing liquid 29 in this case comprises condensate, which has previously accumulated in the air-to-air heat exchanger 5 and was pumped from a condensate tray 17 by means of a pump 28 via a condensate channel 18 into the reservoir 19.
  • the lower container opening 21 is opened and the rinsing liquid 29 is passed through the cleaning line 20 into the air-air heat exchanger 5.
  • the flushing liquid 29 is collected in the condensate pan 17 and pumped back into the flushing vessel 19. This cycle can be repeated if necessary.
  • the drum 3 is in the in Fig. 1 shown embodiment at the rear bottom by means of a pivot bearing and front mounted by means of a bearing plate 16, the drum 3 rests with a brim on a sliding strip 8 on the bearing plate 7 and is held at the front end.
  • the control of the dryer via a control device 10, which can be controlled by the user via an operating unit 9.
  • the fan 6 and the drum 3 are driven by the motor 30.
  • FIG. 2 shows a vertical section through a dryer, which is designed as a circulating air dryer. In this embodiment, therefore, a Zu povertyzugang and an exhaust duct are missing.
  • a cooling air duct 32 In the cooling air duct 32 is a cooling fan 27, which cooling air from a cooling air inlet 26 through the air-air Heat exchanger 5 passes through to the cooling air outlet 31.
  • the fan 6, the cooling fan 27 and the drum 3 are driven by the same motor 30, with the fan 6 and the cooling fan 27 on opposite sides of the motor 30.
  • the cleaning device of the two in the FIGS. 1 and 2 shown dryer is in FIG. 3 outlined.
  • the heat exchanger 5 falls from the flowing process air liquid condensate and drips into the condensate pan 17. From there it promotes the pump 28 through the condensate channel 18 to the washing tank 19, which are also removed after completion of a drying process for the purpose of disposing of the condensate from the dryer can.
  • An emergency overflow 36 makes it possible for excess condensate to reach the condensate tray 17 when the washing container 19 is completely filled.
  • a connection 33 together with a two-way valve 34 a lack of rinsing liquid may possibly be supplied from a water supply 35, not shown here.
  • a level switch 37 the necessary filling of the washing container 19 can be ensured.
  • the solenoid valve 38 is opened abruptly at the rinse tank 19, and rinsing liquid flows through the cleaning line 20 and the adjoining distributor 39 via the heat exchanger 5, so that it is cleaned of adhering lint and other dirt.
  • the rinsing liquid then passes into the condensate tray 17 and can be returned from there through the condensate channel 18 to the rinsing container 19 again, if appropriate with appropriate filtering for the purpose of separating out entrained lint, etc.
  • the heat exchanger 5 is not to be regarded simply as an air-to-air heat exchanger 5, but as a representative of a heat exchanger 5, which is part of a heat pump, in particular a heat sink of this heat pump.
  • a heat exchanger 5 which is part of a heat pump, in particular a heat sink of this heat pump.
  • the present new teaching offers a possibility for the realization of a particularly user-friendly and functionally reliable dryer.
