  • the laundry in the tumble dryer is first completely dried. Then, in an additional step, water is sprayed from a nozzle onto the dry laundry. For this, e.g. By means of a pump, spray water is removed from the condensation container of the tumble dryer in order to avoid having to use additional water.
  • spray water is removed from the condensation container of the tumble dryer in order to avoid having to use additional water.
  • the sprayed water can not or hardly evaporate due to the relatively low temperature of the laundry, this is more a moistening of the laundry by spraying than by vapor deposition.
  • a washing machine known which can produce water vapor.
  • water is passed into a steam device inside the housing of the washing machine.
  • the steam device is a plate which can be heated by induction from a surrounding coil. The water evaporates on the plate and is then treated as water vapor via a nozzle in the interior of the Laundry drum initiated.

  • the non-contact heating unit is an induction heating unit.
  • This may comprise a coil or a plurality of coils, which may be supplied with a high-frequency alternating current or may cause inductive heating by means of a primary magnetic field in the radially outer layer of the material of the laundry drum.
  • the laundry drum is for this purpose preferably formed from a ferromagnetic material or has at least partially on a ferromagnetic material.
  • the heating effect on ferromagnetic materials in the vicinity of the induction heating unit can be limited, so that unwanted effects on other elements within the tumble dryer can be avoided.
  • the contactless heating unit and the liquid dispensing unit are arranged offset to one another in the circumferential direction of the laundry drum.
  • the laundry drum can first be heated by the heating unit before the liquid is dispensed onto the laundry drum.
  • the liquid dispensing unit is preferably arranged downstream of the heating unit in the direction of rotation of the laundry drum.
  • the contactless heating unit may e.g. be placed in the top of one of the corners of the housing of the clothes dryer, where usually next to the cylindrical laundry drum is sufficient space for an additional non-contact heating unit. Furthermore, a sufficient distance to the low-lying region of the laundry drum can be taken in this way, so that the laundry, which can preferably accumulate down in the laundry drum, can be protected by the contactless heating unit before heating the laundry drum.

  • a temperature detection of the laundry drum can take place in order, for example, to only to dispense liquid onto the laundry drum when and / or as long as the laundry drum is at a temperature of e.g. at least about 90 ° C, which can lead to an effective evaporation of the liquid.
  • the required detection of the temperature of the laundry drum can be done via a temperature sensor.
  • the temperature sensor is preferably to be arranged at a location above the laundry drum or in the upper region of the space of the laundry drum, so that the temperature detection of the laundry drum can be made there, where usually no laundry is applied to the inside of the laundry drum, as this could falsify the measurement result.
  • the contactless heating unit is usually arranged in this area of the tumble dryer, so that the laundry can not be overheated and damaged by the contactless heating unit if the laundry drum comes to a standstill during operation of the contactless heating unit at least for a short time. It can also be achieved hereby that the temperature sensor can detect the temperature of the laundry drum as directly as possible when this region of the laundry drum has passed the contactless heating unit and thus has its maximum temperature of the current revolution of the laundry drum.
  • the temperature sensor is arranged fixed radially outside the laundry drum. This can simplify the electrical supply of the temperature sensor and signal transmission away from the temperature sensor and make safer. This can also be cheaper than a temperature sensor that would move with the laundry drum. Furthermore, a relative to the rotating laundry drum fixedly arranged temperature sensor can detect him passing rotating laundry drum over its entire circumference.
  • the clothes dryer further includes a humidity sensor configured and arranged to detect moisture within the laundry drum. In this way, this measurand can also be detected, e.g. to control or regulate the use of evaporation at all or the amount of steam generated depending on the humidity within the laundry drum.
  • the humidity sensor is disposed radially outwardly of the laundry drum. This can simplify the electrical supply of the moisture sensor and the signal transmission away from the moisture sensor and make it safer. This can also be cheaper than a moisture sensor that would move with the laundry drum.
  • the temperature of the laundry drum is detected and the delivery of the liquid to the laundry drum is not started until a predetermined temperature of the laundry drum is reached.
  • This temperature may e.g. at about 90 ° C, since from this temperature effective and rapid evaporation of the liquid can be achieved.
  • the delivery of liquid to the laundry drum takes place only when the fastest possible and complete evaporation of the liquid due to the sufficient heating of the laundry drum can also be ensured. This can also ensure that the laundry is not moistened by non-evaporated liquid.
