Definitions

  • the present invention relates to a rotary-drum household laundry dryer to which the following description refers purely by way of example without implying any loss of generality.
  • rotary-drum household laundry dryers currently on the market generally comprises: a substantially parallelepiped-shaped, outer boxlike casing structured for resting on the floor; a substantially cylindrical rotatable drum which is structured for housing the laundry to be dried and which is housed in axially rotating manner inside the casing so to rotate about a substantially horizontally-oriented longitudinal reference axis, directly facing a laundry loading/unloading opening formed in the front wall of the casing; a hinged to the front wall of the casing to rotate to and from a closing position in which the door rests completely against the front wall of the casing to close the laundry loading/unloading opening and airtight seal the rotatable drum; an electrically-powered motor assembly which is housed inside the casing and is structured for driving into rotation the rotatable drum about its longitudinal reference axis; a closed-circuit, hot-air generator which is housed inside the casing and is structured to circulate inside the rotatable drum a stream of hot air which has a very low moisture content
  • the rotatable drum further consists in a substantially cylindrical, rigid tubular body which is generally made of metal material and extends substantially horizontally inside the boxlike casing, locally aligned to the laundry loading/unloading opening.
  • This rigid tubular body may be furthermore structured for resting on a number of idle supporting rollers which are arranged at the two axial ends of the tubular body locally parallel to the drum longitudinal reference axis, and are fixed to the boxlike casing in free revolving manner so as to allow the tubular body to freely rotate about its horizontally-oriented longitudinal reference axis.
  • the circular front rim of the tubular body surrounds the laundry loading/unloading opening and is coupled in substantially airtight and axially rotating manner to the front wall of the boxlike casing; whereas the circular rear rim of the tubular body abuts against the rear wall of the boxlike casing and is coupled in substantially airtight and axially rotating manner directly to said rear wall.
  • the closed-circuit, hot-air generator in turn comprises: an air recirculating conduit which extends on the bottom of the box-like casing and has a first end directly connected to a first air-vent realized in the rear wall of the boxlike casing, within the perimeter of the rear rim of the tubular body, and a second end directly connected to a second air-vent realized on the annular frame that delimits the laundry loading/unloading opening on the front wall of the appliance casing; and an electrically-powered centrifugal fan which is located along the air recirculating conduit and is structured to produce an airflow which flows in closed loop through the air recirculating conduit and the rotatable drum.
  • the stream of hot air produced by the hot-air generator generally enters into the tubular body via the first air-vent realized in the rear wall of the boxlike casing, flows inside the tubular body for the entire length of the latter, and finally comes out of the tubular body via the second air-vent realized on the annular frame that delimits the laundry loading/unloading opening on the front wall of the casing.
  • the closed-circuit hot-air generator further comprises: an air-cooling device which is located along the air recirculating conduit, and is structured to cool the most air arriving from the rotatable drum, so as to cause the condensation of the surplus moisture inside the airflow; an air-heating device which is located along the air recirculating conduit, downstream of the air-cooling device, and which is structured for heating the dehumidified airflow arriving from the air-cooling device and directed back to the rotatable drum, so that the airflow directed back into the rotatable drum is heated to a temperature preferably, through not necessarily, higher than or equal to that of the moist air flowing out of the same rotatable drum.
  • the closed-circuit hot-air generator is finally provided with an air-filtering member which is arranged along the air recirculating conduit, upstream of the air-cooling device, to prevent the fluff and/or lint particles from reaching and clogging up the air-cooling device, the air-heating and the centrifugal fan.
  • the air-filtering member consists in a substantially wedge-shaped filtering cartridge which is fitted in removable manner into an air-filtering cartridge seat realized on the annular frame that delimits the laundry loading/unloading opening on the front wall of the casing so as to cover/close the whole seat.
  • the user is allowed to manually extract the wedge-shaped filtering cartridge from the seat realized on the annular frame that delimits the laundry loading/unloading opening for periodically cleaning.
  • a gasket is positioned between the air filtering cartridge seat and the air filtering cartridge itself.
  • the bag-shaped shell is furthermore divided into two complementary valve-like pieces which are laterally hinged to one another at the bottom of the bag- or pocket-shaped air-filtering rigid shell, so that the rigid shell is openable in a book-like manner; and each valve-like piece is provided with a substantially flat, large permeable-to-air sidewall which is structured to restrain the fluff and/or lint particles within the bag-shaped rigid shell.
  • the wedge-like air-filtering cartridge furthermore comprises two substantially flat, additional permeable-to-air panels, each of which is structured to restrain the fluff and/or lint particles and is hinged to the upper edge of a respective valve-like piece of the bag- or pocket-shaped air-filtering shell, so as to be foldable towards the inside of the bag- or pocket-shaped air-filtering shell for covering the whole permeable-to-air sidewall of the same valve-like piece, thus improving the air-filtering capabilities.
  • such a portion of recirculating drying air bypassing the air-filtering cartridge may pass through those gaps necessarily present between the air-filtering cartridge and the relative seat for allowing the air-filtering cartridge to be easily inserted in/removed from the air-filtering cartridge seat.
  • the fluff and/or lint particles are thus deposited within such gaps, and particularly around the outer surface of the air-filtering cartridge.
