Definitions

  • the invention relates to a lint filter device for an air flow in a tumble dryer with an endless circulating element, which is arranged circumferentially around at least two deflecting elements and is positioned so that it is crossed by the air flow, wherein the circulating element has an upper edge and a lower edge. Furthermore, the invention also relates to a method for cleaning such a lint filter device.
  • Dryers which have lint filter devices are known in many ways. However, the cleaning of this lint filter device is usually very expensive and yet inadequate.
  • German Offenlegungsschrift DE 40 23 129 A1 discloses an electric tumble dryer which has a coarse sieve body arranged there in the region of a feed opening and a finely sieve body arranged downstream of the coarse sieve body.
  • the coarse sieve body must be pulled out to remove the lint adhering to the fine sieve body.
  • a scraper which is arranged on the Grobsieb stresses strikes the Feinsieb stresses, whereby the adhering thereto lint be removed. Cleaning or removal of lint can be achieved only by removing the coarse sieve body.
  • a tumble dryer with a lint filter known.
  • the lint filter is arranged as a fixed immovable element in an air flow of the clothes dryer.
  • a scraper is provided which has a toothed drive rod on its side facing away from the exhaust duct.
  • Engaging with the toothing of the drive rod is a drive pinion which is rotatable by a gear drive in rotation when a fixedly connected to the loading door gear segment is moved when opening the loading door.
  • the scraper moves over the surface of the lint filter facing the exhaust air and strips lint from it.
  • the cleaning takes place here by an automatic actuation of the Scraper when opening the loading door of the tumble dryer. Again, the removal of the lint from the fixed lint filter can be performed only very inadequate.
  • EP 1 050 619 B1 discloses an automatically to be cleaned lint filter device for household laundry driers.
  • the lint filter device comprises an endlessly circulating around two deflection elements circulating element, which is arranged in an air flow.
  • the circulating element is moved in the direction of rotation and passed a fixed scraper. If the cleaning process of the air flow facing the front portion of the circulating element is completed, the rotational movement of the deflecting elements is reversed, so that the front region of the circulating element (the air flow-facing region of the circulating element) returns to its original position.
  • the cleaning process can only be carried out very inadequately and moreover also only with great difficulty.
  • the circulation element is positioned so that it is crossed by the air flow.
  • the circulation element has an upper and a lower edge.
  • first engaging elements are arranged at least on one of the two edges, which are in mechanical operative connection with at least one second engagement element when opening a loading door of the dryer or are mechanically coupled with this, by the further opening process the feed door, the circulating element automatically in a direction of rotation and at least on a device for removing lint from the circulating element is passable.

This can ensure that when moving the circulation element, the entire height between the upper and the lower edge of the circulation element is detected by the device for removing lint and the lint can be reliably removed in the entire area.
  • the device for removing fluff is movable counter to the direction of rotation of the circulating element that can be effected during the opening process of the loading door.
  • the device for removing lint is preferably coupled with the second engagement element during the opening process of the loading door such that the movement of the device for removing the lint is automatically effected by the opening operation of the loading door.
  • the device for removing fluff after a cleaning operation of the circulating element via a cleaning device for cleaning the device for removing lint is movable.
  • the device for removing lint can thus be provided clean ready for each subsequent cleaning operation of the circulation element, whereby the cleaning process of the circulation element is positively influenced.
