  • far-infrared heaters are arranged on or outside drying drums of the clothes dryers or the washing-drying integrated machines; the far-infrared heaters can emit far-infrared rays; the far-infrared rays have an energy characteristic of being absorbed by water but not absorbed by air; therefore, the far-infrared rays are radiated to interiors of the drying drums, are absorbed by water in heated objects, and are directly converted into a heat energy for converting the water in the heated objects into water vapor to be drained out.
  • the existing clothes dryers or washing-drying integrated machines use the far-infrared heating technology; on and off of a group of far-infrared heaters are usually controlled by a relay arranged on a PCB (Printed Circuit Board); a temperature controller is mounted near each of the far-infrared heaters to prevent that the temperature of the far-infrared heater is too high; and a temperature sensor is arranged in the drying drum to control that the temperature inside the drum is not excessive.

  • the first temperature sensor 5 is mounted inside the far-infrared heater 1; current of the far-infrared heaters 1 has a characteristic of increasing gradually; all the far-infrared heaters 1 are controlled by only one relay 3, rather than respectively controlled by a plurality of relays 3. In this way, the system can control all the far-infrared heaters 1 by using only one first temperature sensor 5 and one relay 3, to simplify circuits and also save cost.
  • the far-infrared heaters 1 can be mounted on the clothes-drying drum or mounted between the clothes-drying drum and the tank body.

  • the far-infrared heaters 1 are configured to heat clothes; the temperature of the far-infrared heaters 1 is locked, e.g., the temperature of a 200 membrane system is not higher than 200°C, and the far-infrared heaters are automatically powered off when the temperature exceeds 200°C; furthermore, the clothes are not heated by an air medium, but water of the clothes is directly heated by emitted far-infrared radiation; these two aspects ensure use security firstly, so the temperature sensor arranged in the clothes-drying drum in a traditional clothes-drying system is no longer so important, and temperature detection accuracy in the clothes-drying drum is no longer dependent on the air speed.
