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 comprise: a substantially parallelepiped-shaped outer boxlike casing able to rest on the floor; a substantially cylindrical revolving drum able to house the laundry to be dried, and in turn which is housed in axially rotating manner inside the casing to rotate about its horizontally-oriented longitudinal axis, directly facing a laundry loading/unloading opening formed on the front wall of the casing; a 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 revolving drum; and an electric motor assembly which rotates the revolving drum about its longitudinal axis inside the casing.
  • Home laundry dryers of the above kind are also provided with an open-circuit (or a closed-circuit), hot-air generator which is structured to circulate inside the revolving drum a stream of hot air having a low moisture content, and which flows through the revolving drum and over the laundry inside the drum to rapidly dry the laundry; and with an electronic central control unit which controls both the motor assembly and the hot-air generator to perform one of the user-selectable drying cycles stored in the same central control unit.

  • an electronic central control unit which controls both the motor assembly and the hot-air generator to perform one of the user-selectable drying cycles stored in the same central control unit.
  • the hot-air generator is usually a closed-circuit, heat-pump type, hot-air generator that comprises: an air recirculating conduit presenting its two ends connected to the revolving drum, on opposite sides of the latter; an electrically-operated centrifugal fan located along the air recirculating conduit to produce, inside the latter, an airflow which flows through the revolving drum; and finally a heat-pump assembly provided with two heat exchangers located one after the other, along the air recirculating conduit.
  • EP-2034084 discloses a heat-pump type, rotary-drum home laundry dryer of the aforementioned kind.
