Specifically, 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.
  • However, 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. As a result, if an existing far-infrared heating control mode is used, one relay and one temperature controller need to be configured for each far-infrared heater, and multiple groups of relays and temperature controllers need to be arranged in the entire clothes dryer or washing-drying integrated machine, to result in complicated circuits and waste of cost.

    • DETAILED DESCRIPTION
  • In order to make solved technical problems, adopted technical solutions and achieved technical effects of the present invention clearer, the technical solutions of embodiments of the present invention are further described in detail in combination with the drawings below. Apparently, the described embodiments are merely some embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those skilled in the art without paying creative efforts fall within a protection scope of the present invention, based on embodiments of the present invention.
    • Embodiments of device
  • The far-infrared heater provided by the present application can be applied to a washing-drying integrated machine and can also be applied to a clothes dryer; and the clothes dryer is introduced below as an example. The clothes dryer includes a tank body and a far-infrared clothes-drying control system; the far-infrared clothes-drying control system includes a clothes-drying drum, which is rotatably arranged inside the tank body. Fig. 1 is a schematic structural diagram illustrating the far-infrared clothes-drying control system provided by device embodiments of the present invention. As shown in Fig. 1, the far-infrared clothes-drying control system further includes at least one far-infrared heater 1, a humidity sensor 6 for detecting exhaust humidity of the clothes-drying drum, a relay 3 and a controller 2 having an output end connected with the relay 3; the controller 2 is connected with a power supply 4; all the infrared heaters 1 are connected with the power supply 4 through the relay 3; a first temperature sensor 5 is mounted inside one of the far-infrared heaters 1; the first temperature sensor 5 and the humidity sensor 6 are connected with an input end of the controller 2; and the controller 2 controls on and off of the relay 3 according to a received temperature signal or humidity signal.
  • During operation, the first temperature sensor 5 detects temperature in the far-infrared heaters 1 and transmits the temperature to the controller 2 in the form of signal; meanwhile, the humidity sensor 6 detects humidity of gas discharged from the clothes-drying drum and transmits the humidity to the controller 2 in the form of signal.
  • The controller 2 compares the received temperature in the far-infrared heaters with a preset upper limit temperature Tmax1 and a preset lower limit temperature Tmin1, controls the relay 3 to be turned off when the temperature in the far-infrared heaters is higher than the preset upper limit temperature Tmax1, and controls the relay 3 to be turned on when the temperature in the far-infrared heaters is lower than the preset lower limit temperature Tmin1; and meanwhile, the controller 2 compares the received humidity value with a preset humidity value, and controls the relay 3 to be turned off and terminates a drying process when the humidity value is less than the preset humidity value.
  • Since the far-infrared heater 1 itself has a temperature limiting characteristic (temperatures are different according to different TCM systems, generally 200-400°C) and a high degree of consistency; 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. Specifically, 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.
  • In the present embodiment, the far-infrared heaters 1 can be mounted on the clothes-drying drum or mounted between the clothes-drying drum and the tank body. When the far-infrared heaters 1 are mounted on the clothes-drying drum, mounting holes are arranged in the clothes-drying drum; and the far-infrared heaters 1 are mounted in the mounting holes so as to heat interior of the clothes-drying drum.
  • In the present embodiment, as another preferred solution, when the far-infrared heaters 1 are mounted between the clothes-drying drum and the tank body, at least one group of hole arrays is arranged on the clothes-drying drum; each group of the hole arrays is composed of a plurality of holes; and the far-infrared heaters 1 are arranged outside the hole arrays, and can heat interior of the clothes-drying drum through the hole arrays.
  • Since normal operation temperature of the far-infrared heaters used in the clothes-drying system in the existing art is 600 °C and may reach to 1000 °C under abnormal conditions, control of the temperature is particularly important; besides the above-mentioned temperature detection and protection for the far-infrared heaters, 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.
  • In the control system, 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.
  • Therefore, in the present embodiment, as a preferred solution, at least one second temperature sensor 7 is further arranged on the clothes dryer; the second temperature sensor 7 is connected with the input end of the controller 2, for detecting the temperature in the clothes-drying drum and transmitting the temperature to the controller 2; the controller 2 compares the received temperature in the clothes-drying drum with a preset upper limit temperature Tmax2 and a preset lower limit temperature Tmin2, controls the relay 3 to be turned off when the temperature in the clothes-drying drum is higher than the preset upper limit temperature Tmax2, and controls the relay 3 to be turned on when the temperature inside the clothes-drying drum is lower than the preset lower limit temperature Tmin2.
  • In the present embodiment, as a preferred solution, the second temperature sensor 7 is arranged at an air outlet of the clothes dryer.
  • In the present embodiment, 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 Tmax2 and the preset lower limit temperature Tmin2.
  • In the present embodiment, as a preferred solution, 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.
  • In the present embodiment, since a low-power fan is used in the control system, hot and humid gas may be aggregated toward the air outlet at the top of the clothes dryer; and therefore, as a preferred solution, the humidity sensor 6 is placed at the air outlet of the clothes dryer in order to more accurately measure the humidity.
  • In the present embodiment, as a preferred solution, the controller 2 is made into a PCB integrated circuit board.
