  • the control system no longer adopts a mechanical temperature controller, but only one first temperature sensor 5 is mounted on one far-infrared heater 1 for detecting and controlling temperature.
  • 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.

  • a temperature sensor is further arranged in the clothes-drying drum; the temperature sensor is configured to detect the temperature in the clothes-drying drum and prevent clothes from being damaged due to excessively high temperature in the clothes-drying drum, which requires the whole machine to be equipped with a high-power fan, so as to make the temperature in the drum as even as possible, so that security problems may occur when an air speed is slightly lower, or an air duct is slightly blocked.
  • 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. However, for the clothes to be dried, if the clothes are made of chemical fibers, wools and other fabrics with high temperature requirements, the requirements for the temperature in the clothes-drying drum are also relatively high.

  • the number of the second temperature sensors 7 is at least one; when the number of the second temperature sensors 7 is plural, after all the second temperature sensors 7 transmit the detected temperatures in the clothes-drying drum to the controller 2 ; the controller 2 averages all the received temperatures in the clothes-drying drum, and then compares an average value with the preset upper limit temperature Tmax 2 and the preset lower limit temperature Tmin 2 .
  • a fan 8 is arranged at an air inlet of the clothes dryer; power of the fan 8 is 10-20 W; the fan 8 is connected with the controller 2 ; and the controller 2 controls rotation of the fan 8 . Since the control system avoids dependence on air speed, the use of the high-power fan is avoided, and only one smaller fan is required for auxiliary dehumidification; and therefore, noise of such clothes dryer is low.
