Definitions

  • the present invention relates to a control method for controlling a tumble laundry drier for drying wool laundry.
  • Drying woollens poses serious difficulties, on account of the tendency of woollens to felt, thus resulting in irreparable damage. Felting of woollens is caused by overheating the wool, and by the woollens rubbing against the inner surface of the drum or against other woollens.
  • Felting of woollens caused by overheating can be prevented by simply reducing and accurately controlling heating of the woollens during the drying process.
  • Drying woollens in a rack results in uneven drying, in that, at the end of the drying process, the woollens are perfectly dry on the outside, but still relatively damp on the inside. Furthermore, the rack represents an extra cost for the customer, and is also cumbersome and therefore difficult to store when not in use. Finally, using a rack, the relative humidity of the woolens cannot be measured during the drying cycle, to stop the drying cycle when the humidity of the woollens reaches a given value. Consequently, using a rack, the drying cycle must be of constant predetermined duration, regardless of the actual weight and initial humidity of the woollens.
  • EP 1 103 648 discloses a method and an apparatus for drying clothes, in which the temperature of the drying air is pre-set in accordance with the type of clothes to be handled.
  • the rotating speed of the drum is variable within ranges that are pre-set in accordance with the type of clothes being handled in a manner that is proportional to the amount of water that is removed from the clothes, i.e. inversely proportional to the desired drying degree.
  • the rotating speed is higher in the case of woollen clothes so as to causes them to remain pressed, albeit gently, against the skirt of the drum, so that they are no longer tossed about repeatedly as it occurs in traditional machines and the fibres are practically preventing from becoming matted together, i.e. from felting.
  • DE 23 06 111 disclosed a method for drying sensitive types of fabric, in particular wool, in a laundry treatment machine provided with a drum; the drum remains motionless for most of the time during the drying cycle, only being actuated for a brief period at regular intervals at a speed of rotation that only results in acceleration below a value of 1 g.
  • Number 1 in Figure 1 indicates as a whole a laundry drier comprising a casing 2 resting on a floor on a number of feet.
  • Casing 2 supports a revolving laundry drum 3, which defines a drying chamber 4 for the laundry 5 to be dried, rotates about a horizontal rotation axis 6 (in alternative embodiments not shown, rotation axis 6 may be tilted or vertical), and has a front access opening closed by a door 7 hinged to a front wall of casing 2.
  • Drum 3 is rotated by an electric motor 8, and is fed through with a stream of drying air fed into drum 3 by a centrifugal fan 9 and heated by a heating device 10.
  • fan 9 produces a stream of dry air that is fed to heating device 10 and then into drum 3 through a perforated back of the drum. After contacting laundry 5, the dry air flows out of drum 3 to a condenser 11, in which it is cooled to condense the laundry moisture contained in it. For which purpose, condenser 11 is fed through with cooling air drawn in from outside tumble laundry drier 1; and the dry air from condenser 11 is drawn in again by fan 9.
  • condenser 11 is referred to here purely by way of example in connection with one embodiment of the present invention, and may be omitted in the case of an exhaust-type tumble laundry drier 1 (i.e. in which the hot drying air from drum 3 is exhausted directly to the outside).
  • the rotation speed of electric motor 8, which rotates drum 3 about rotation axis 6, is controlled by an electronic control unit 12, which receives the input commands from the user of tumble laundry drier 1. More specifically, electronic control unit 12 performs a wool drying cycle specially designed for felt-free drying wool laundry 5.
  • electronic control unit 12 controls heating device 10 to reduce heating of the drying air and hence the temperature of wool laundry 5 to well below the felting temperature of the wool.
  • drum 3 is rotated at a constant rotation speed n 1 greater than rotation speed n 2 at which centrifugal acceleration of the inner surface of drum 3 equals gravitational acceleration, so wool laundry 5 is pressed by centrifugal force against the inner surface of drum 3, as opposed to dropping inside drum 3.
  • rotation of drum 3 is stopped cyclically by zeroing rotation speed n, and drum 3 is re-accelerated back to rotation speed n 1 to rearrange wool laundry 5 inside drum 3.
  • centrifugal acceleration greater than gravitational acceleration i.e.
  • wool laundry 5 is rearranged cyclically inside drum 3 by cyclically stopping drum 3 for about 2 seconds (generally about 1-3 seconds).
  • rotation of drum 3 should be stopped cyclically every 5-15 minutes and, preferably, about every 10 minutes.
  • rotation speed n 1 is about 70 rpm (revolutions per minute) and, more generally, ranges between 65 and 75 rpm, for a drum 3 of 575 mm in diameter.
  • rotation speed n 1 must not be too close to rotation speed n 2 .
  • rotation speed n 1 must not be too far from rotation speed n 2 , to avoid excessive mechanical stress of wool laundry 5 caused by high centrifugal acceleration.
  • rotation speed n of drum 3 is decreased/increased with a deceleration/acceleration of about 20-35 revolutions/second 2 (i.e. drum 3 needs about 2-3 seconds to decelerate/accelerate from 70/0 rpm to 0/70 rpm).
  • drum 3 needs about 2-3 seconds to decelerate/accelerate from 70/0 rpm to 0/70 rpm.
  • electronic control unit 12 determines the position of wool laundry 5 inside drum 3, and stops drum 3 so that, when drum 3 is stopped, wool laundry 5 is at the bottom of drum 3. This prevents wool laundry 5 from dropping inside drum 3 when the drum is stopped, and so further reduces mechanical stress of wool laundry 5. More specifically, drum 3 has three lifters 15, each with a sensor 16 for sensing the presence of wool laundry 5; and electronic control unit 12 determines the lifter/s 15 contacting wool laundry 5, and stops drum 3 so that, when drum 3 is stopped, the lifter/s 15 contacting wool laundry 5 is/are in a low position (for example, by commencing stoppage of drum 3 when the lifter/s 15 contacting wool laundry 5 is/are about 120° upstream from its/their lowest position).
  • Figure 2 shows a graph of rotation speed n of revolving drum 3 during the wool drying cycle. As shown in Figure 2 , during the wool drying cycle, rotation speed n is kept substantially constant at rotation speed n 1 greater than rotation speed n 2 , and drum 3 is stopped cyclically.
  • Electronic control unit 12 is connected to a humidity sensor 13 to measure the relative humidity of wool laundry 5 during the wool drying cycle.
  • Humidity sensor 13 comprises a pair of electrodes 14 contacting wool laundry 5 inside drum 3 to measure the resistance/conductivity of wool laundry 5, and uses the resistance/conductivity of wool laundry 5 to determine the humidity of wool laundry 5.
  • Electronic control unit 12 stops the wool drying cycle when the electric resistance/conductivity between the two electrodes 14 is above/below a resistance/conductivity threshold (i.e. the humidity of wool laundry 5 is below a humidity threshold).
  • the resistance/conductivity measured between the two electrodes 14 immediately after a cyclic stop in rotation of drum 3 is compared with the resistance/conductivity threshold.
  • Wool drying cycle as described above has numerous advantages, by being cheap and easy to implement in a standard tumble drier (no additional components, other than those normally featured in a modern tumble drier are required), and by enabling careful (i.e. felt-free) but nevertheless effective drying of wool laundry. More specifically, determining the end of the drying cycle on the basis of the measured humidity (i.e. electric resistance/conductivity) of the laundry to be dried, the wool drying cycle as described above minimizes mechanical stress of the wool laundry (i.e. eliminates undue mechanical stress caused by a longer than necessary drying cycle), is effective (i.e. at the end of the drying cycle, the wool laundry is as dry as necessary), and is efficient (i.e. the drying cycle wastes no electric energy) regardless of variations in the weight and initial humidity of the wool laundry to be dried.
  • the measured humidity i.e. electric resistance/conductivity
