Definitions

  • the present invention relates to a tumble dryer with a humidity sensor system.
  • Tumble dryers and other domestic appliances require a humidity sensor in order to obtain information about the actual humidity of the laundry in the drum or of the air exiting the latter. This information is used for controlling the tumble dryer, e.g. for stopping the drying cycle when the detected humidity of the laundry is below a prefixed value.
  • DE 195 21 625 C1 discloses a humidity sensor for a tumble dryer.
  • the humidity sensor includes a pair of contact stripes fastened at a plastic wall of the air channel.
  • One end of the strip has a particular shape and forms a spring engaging a hole obtained in the wall.
  • the costs of these electrodes are high, since elastic as well as conductive metal is required.
  • the thermal deformations of the electrodes due to the high variations of the temperature in the dryer may cause that the elasticity of the spring end is reduced. This results that the fastening of the electrode should be compromised.
  • US 3,593,571 discloses a dryness sensor assembly including a pair of electrodes. The fixation of the electrodes requires clip means. Thus, this dryness sensor assembly is relative expensive and the installation of this dryness sensor assembly is time-consuming.
  • US 4,899,464 discloses a moisture sensor for an automatic tumble dryer. Sensor strips are secured directly to the drum. The fastening of the sensor strips is less effective. The assembly of the sensor strips is quite difficult, since after placing the first end of the sensor strips in a corresponding aperture, the introducing of the second end in the corresponding aperture the sensor strip or at least its second end has to be bent with the risk of damaging it.
  • EP1473402 discloses a sensor assembly for an automatic drying machine with a rotatable drum including one sensing element disposed on a surface of an elongated sensor body exposed to an inside of the drum to make contact with a drum contents.
  • the sensor body is secured to a bulkhead having an air outlet opening and is provided at the air outlet opening for effective engagement with the drum contents.
  • the object of the present invention is achieved by the tumble dryer with the humidity sensor system according to claim 1.
  • the tumble dryer comprises:
  • the support comprises at least two seats or channels for receiving the electrodes; each seat or channel comprises at least one retaining element adapted for retaining a respective electrode into the seat or channel.
  • the at least one retaining element may be obtained in a single piece construction with the respective seat or channel.
  • the at least one retaining element protrudes from the side wall of the respective seat or channel towards the internal of the seat or channel.
  • the electrodes comprise a lateral border and the at least one retaining element is arranged in such a way to extend over the border of the respective electrode when the latter is placed into the respective seat or channel, so as to clamp the border and to fix the electrode into the seat or channel.
  • the electrodes comprise a first appendix or end inserted in or insertable into a first opening obtained in a portion of the respective seat or channel, so that the first appendix or end protrudes externally from the seat or channel.
  • the first appendix or end is connected or connectable to electric connections for connecting the electrode to the detection circuit and/or control unit.
  • a second end of the electrodes is inserted in or insertable into a second opening obtained in the respective seat or channel.
  • the electrodes and the respective channels have an elongated shape.
  • each electrode is moveable within a respective seat or channel about a predetermined length and along the common longitudinal axis of the electrode and seat or channel.
  • the electrode comprises a lateral border comprising at least one cut in order to overcome the at least one retaining element during inserting the electrode into the respective seat or channel.
  • the cut is arranged at the border in such a way that, after inserting the electrode into the respective seat or channel, the at least one retaining element overlaps the border and keeps the electrode within the seat or channel after the electrode has been properly moved internally to the seat or channel.
  • the support is associated to, or associable to, or comprised into a front wall or flange or bulkhead associated to the casing of the tumble drier.
  • the electrode is at least partially disappearing within the channel, wherein said electrode is clampable by the retaining element of the channel and the border of electrode.
  • the electrode advantageously requires no material with special mechanical properties.
  • the electrode is moveable within the channel about a predetermined length and along the common longitudinal axis of the electrode and channel.
  • At least one end of the electrode is inserted in or insertable into an opening in an end portion of the channel.
  • both ends of the electrode may preferably be inserted in or insertable into openings in the both end portions of the channel.
  • At least one end of the electrode is longer than the predetermined length defining the movability of the electrode within the channel along the common longitudinal axis. At first the longer electrode is inserted into the corresponding opening. Then the other electrode is inserted into the opposite opening. At last, the electrode is moved into the direction of said other electrode.
  • the retaining element extends from the longitudinal side wall of the channel inside said seat or channel and perpendicular to the longitudinal axis of the seat or channel.
  • the seat or channel may comprise at least one recess corresponding with the retaining element, so that the border of the electrode is clampable between the retaining element and said recess.
  • the border of the electrode may comprise at least one cut in order to overcome the retaining element during inserting said electrode into the channel. The cut simplifies the inserting of the electrode into the channel.
  • the cut is arranged at the border, so that the retaining element supports the border and keeps the electrode within the seat or channel after the electrode has been moved about the predetermined length and along the common longitudinal axis.
  • This is an efficient latching mechanism.
  • a main part of the electrode is formed as a U-shaped profile section. This contributes to an increased stability and allows that a substantial part of the electrode is exposed to the contact with the laundry loaded into the drum.
  • the invention relates to a tumble dryer comprising:
  • the support is attached or attachable at a seat arranged in an inner side wall or flange or bulkhead comprised or contained in the casing of the tumble drier; at least one hole is advantageously arranged in the inner side wall or flange or bulkhead for conducting electric cables connecting the electrodes to the detection circuit and/or control unit; the support comprises at least one appendix or wing for covering at least partially the hole.

  • the wing is provided to obstruct at least partially a clearance between the hole and the support in order to prevent that moisture enters said clearance. This reduces the risk of damage the electronic components arranged downstream the hole.
  • the wing is formed as a protruding sheet.
  • the seat is complementary to the support, so that the support is form-locking within the inner side wall of an air stream channel.
  • the support may be attached or attachable at a flange enclosing an opening of the tumble dryer.
