Definitions

  • the invention relates to a tumble dryer with a laundry drum, with a fan for conveying process air, with a heater for heating up the process air and optionally with a condenser cooled by a further fan.
  • a dryer of the type mentioned is z. B. become known from DE-PS 29 14 859.
  • This tumble dryer is a condensation tumble dryer, in which the laundry drum with the fan for conveying the process air, with a condenser and with the heater for the process air is in a closed circuit.
  • a further fan for cooling the condenser is provided.
  • Such tumble dryers can either have a single motor for driving the laundry drum and the two fans, or they can each have a motor both for the laundry drum and for the fans.
  • a motor for driving the laundry drum and a motor for driving both fans can be provided.
  • Such tumble dryers are very common in the living area of a household, for. B. in the bathroom, and are used in night mode. The noise generated by the dryer can be very annoying. The fans are particularly responsible for this noise.
  • the invention is therefore based on the object that produced by a tumble dryer of the type mentioned Reduce noise.
  • This object is achieved according to the invention in a tumble dryer of the type mentioned in that the heating power can be reduced compared to its normal value and that the speeds of the circulating air and cooling air blowers can be adjusted to the reduced heating power.
  • This makes it possible to operate the dryer with a reduced heating output if required, which means that the fan speeds can also be reduced because the reduced heating output means that less process air per unit of time is no longer required.
  • the drying time is extended slightly, this is usually insignificant if the dryer is used in particular at night.
  • B. a reduction in heating power and drum and fan speed by 20 to 40%. This means a considerable reduction in the noise generated by the fans, which is particularly advantageous in the case of a dryer operating in a rented apartment during night operation.
  • a further reduction in noise can be achieved in that the speed of the fans can also be set as a function of the load.
  • the heating power and / or the speeds of the fans can preferably be set continuously or in stages. This enables individual adaptation to the respective conditions.
  • the laundry drum can be operated with a separate motor driven and kept constant in their speed, no matter which operating level is set. It would also be possible to operate the motor for the drum at a lower speed in order to further reduce noise.
  • the figure shows a laundry drum 10, which is in a closed circuit with a heater 11 for heating process air, with a fan 12 for conveying the process air and with a condenser 13. With 14 another fan for cooling the condenser 13 is designated.
  • the output of the heater 11 can be reduced, which means that the amount of air conveyed by the fan 12 through the circuit can also be reduced accordingly.
