Definitions

  • the present invention relates to a rotary-drum laundry dryer.
  • the present invention relates to a rotary-drum home laundry dryer to which the following description refers purely by way of example without implying any loss of generality.
  • rotary-drum home laundry dryers currently on the market generally comprise: 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 is housed in axially rotating manner inside the casing in order to rotate about an horizontally-oriented longitudinal reference axis, directly facing a laundry loading/unloading opening formed in the front wall of the casing; a porthole door 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; an open-circuit or 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
  • the rotatable drum furthermore consists in a substantially cylindrical rigid tubular body having open ends, while in a second kind of rotary-drum home laundry dryers said substantially cylindrical rigid tubular body has one end which is closed by a bottom wall rigidly fixed to the tubular body.
  • the rotatable drum extends substantially horizontally inside the boxlike casing, locally aligned to the laundry loading/unloading opening, and is 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 attached to the appliance casing in free revolving manner so as to allow the tubular body to freely rotate about its horizontally-oriented longitudinal reference axis.
  • the front rim of the tubular body surrounds the laundry loading/unloading opening and is coupled in axially rotating manner to the front wall of the boxlike casing; whereas the rear rim of the tubular body abuts against the rear wall of the boxlike casing and is coupled in axially rotating manner directly to said rear wall.
  • the front wall comprises an annular frame and a covering panel; the covering panel belonging to the cabinet of the laundry dryer. In actual use the covering panel covers the annular frame.
  • the stream of hot air produced by the hot-air generator usually enters into the tubular body via an intake air-vent made in the rear wall of the boxlike casing, within the perimeter of the rear rim of the tubular body, flows inside the tubular body for the entire length of the latter, and finally comes out of the tubular body via an escape air-vent usually carried out on the annular frame that delimits the laundry loading/unloading opening on the front wall of the casing.
  • a first circular sealing gasket is generally interposed between the front rim of the tubular body and the front wall of the casing, whereas a second circular sealing gasket is generally interposed between the rear rim of the tubular body and the rear wall of the appliance casing.
  • the first and the second circular sealing gaskets are usually recessed into a circular groove carried out on the front and rear wall of the casing, respectively, and are firmly hold in the groove so as to remain stationary when the rotatable drum rotates about its longitudinal reference axis.
  • the back of the rotatable drum i.e. the rear wall of the boxlike casing or the bottom wall fixed to the tubular body of the drum, may be provided with an anti-entangling nose that protrudes from the rear wall closing the rear end of the drum tubular body, roughly at centre of the rear rim of the tubular body, and extends inside the tubular body locally substantially parallel to the drum longitudinal reference axis.
  • This nose is shaped/dimensioned so to prevent, when the drum rotates, the laundry from entangling and block the hot-air intake vent located on said wall or unbalance the drum rotation.
  • Aim of the present invention is to simplify the structure of the rear wall of the boxlike casing so as to significantly reduce the appliance production costs and simplifying the drying machine assembling process.
  • a rotary-drum laundry dryer comprising a revolving drum structured for housing the laundry to be dried, a hot-air generator structured to supply a stream of hot air through said revolving drum, and a lower supporting base which is structured for resting on the floor and for housing at least part of the hot-air generator.
  • the hot-air generator (6) in turn comprises:
  • the rotary-drum laundry dryer is characterized in that its rear wall comprises a supporting bulkhead made of plastic material; at least a portion of a centrifugal impeller scroll made also of plastic material being carried out in one piece with the supporting bulkhead; and/or at least one supporting boss of a drum supporting roller being also made of plastic material and carried out in one piece with the supporting bulkhead.
  • the rotary-drum laundry dryer is characterized in that its rear wall comprises a supporting bulkhead made of plastic material; at least one supporting boss of a drum supporting roller being also made of plastic material and carried out in one piece with the supporting bulkhead; and at least one supporting boss of a supporting roller being carried out in one piece with a lower supporting basement.

  • the hot-air generator 6 can be a heat-pump which is envisaged for gradually drawing air from the rotatable drum 3; rapidly cooling down the wet air arriving from the rotatable drum 3 so to extract and retain the surplus moisture in the air drawn from the rotatable drum 3; and then rapidly heating the dehumidified air to a predetermined temperature, normally higher than the temperature of the air coming from the rotatable drum 3; and finally feeding the heated, dehumidified air back into the rotatable drum 3, where the air flows over the laundry inside the drum to rapidly dry said laundry.
  • a heat-pump is particularly suitable in carrying out the invention because the dry air which is used for drying the laundry has a quite low temperature and therefore it doesn't damage the plastic components of the casing.
  • the heat-pump assembly (non shown in detail) comprises a first and a second air/refrigerant heat exchangers located inside the air recirculating conduit 21, preferably downstream of the centrifugal fan.
  • the first air/refrigerant heat exchanger traditionally referred to as the "evaporator" of the heat-pump circuit, is located inside the air recirculating conduit 21 preferably downstream of the centrifugal fan, and is structured to remove/absorb heat from the airflow arriving from rotatable drum 3, thus forming the air cooling means of the hot-air generator 6.
  • the second air/refrigerant heat exchanger traditionally referred to as the "condenser" of the heat-pump circuit, is instead located inside the air recirculating conduit 21 downstream of the first air/ refrigerant heat exchanger, and is structured to release heat to the airflow arriving from the first air/refrigerant heat exchanger, thus forming the air heating means of the hot-air generator 6.
