Definitions

  • the present invention relates to a domestic washer-drier machine which provides for washing and drying the laundry.
  • Domestic washer-drier machines are known to comprise a support and housing structure, a washing tank being housed therein, which is provided with a front opening that can be closed by means of a porthole door that is hinged in front of the housing.
  • a basket is pivotally housed about a horizontal or inclined axis, for the laundry to be accommodated therein to be washed and/or dried.
  • the basket also defines a front opening that is located such as to match the opening of the washing tank, in order to load/unload the laundry.
  • the washing tank is suitable to contain the washing liquid during the laundry washing steps and to be a portion of the drying circuit during the laundry drying step.
  • a washing water delivery system that can be connected to the water supply is provided in order to load the tank with mains water and detergent substances and aids.
  • a drain duct is provided with a discharge pump being associated therewith, which provides for the removal of the washing liquid from the tank and controls, together with the supply electrovalves, the level of liquid within the tank.
  • a recirculation duct complete with recirculation pump may be provided having a first intake end connected to the tank bottom to be capable of taking the washing liquid to be recirculated and a second re-feed end of the liquid to the laundry basket which is arranged proximate to the upper portion of the basket.
  • An electric resistance being arranged within the tank in the gap between the tank wall and laundry basket is provided to heat the washing liquid contained in the tank.
  • the drying circuit of prior art washer-drier machines typically comprises an intake unit, a heat exchanger and a heating unit with electric resistances communicating with each other by means of a drying duct.
  • the air flow generated by the intake unit is heated by the electric resistances and blown to the basket, where it causes the water contained within the tissues to evaporate as it passes through the wet laundry.
  • the heat exchanger which is generally a container separate from the washing tank and provided with a spray nozzle, the wet air is cooled by a jet of cold water. Due to this cooling, the vapour condensates and is collected and discharged together with the cooling water. The dehumidified air is then sucked again by the intake unit and recirculated.
  • the cooling water is usually supplied to the heat exchanger by means of a cooling duct with a dedicated electrovalve which controls the loading of the mains water to the heat exchanger (condenser).
  • Prior art drying devices while being satisfactory under many aspects, however, have a high consumption of electric power and cooling water during the drying step.
  • Zeolites are minerals with a regular crystalline and microporous structure comprising a high amount of micro-cavities with a very high total surface and a huge void volume within the crystals. Due to said configuration, zeolites are suitable to contain a considerable moisture amount by means of adsorption of water molecules on the wide surfaces of the microporous structure thereof. By subsequently heating the zeolite mineral, the water molecules are desorbed and released in the form of water vapour.
  • the object of the present invention is to provide a washer-drier machine, having such characteristics as to increase the drying power while reducing the energy and water consumption during the drying step.
  • the washer-drier machine comprises a washing tank suitable to contain the washing liquid, a basket suitable to accommodate the laundry and rotatably supported within the washing tank, a drying circuit with a intake unit, a heat exchanger and a hearing unit communicating with each other by means of a drying circuit, and configured to convey a drying air flow through the basket, wherein the drying circuit further comprises an absorption device having:
  • the washer-drier machine comprises a recirculation duct and a recirculation pump associated therewith, which is suitable to take washing liquid from the tank bottom and re-feed the same in the basket, wherein this recirculation duct is arranged in a heat exchange relationship with the zeolite cartridge of the absorption device and wherein the washer-drier machine is configured such that, during a washing step, the heated and recirculated washing liquid heats the zeolite cartridge so that the latter releases the previously absorbed moisture.
  • the thermal energy of the washing liquid is used to "regenerate" the zeolite cartridge, thus preparing the latter for absorbing moisture during a subsequent drying step.

  • Fig. 2 is an enlarged view of a detail of the washer-drier machine section from Fig. 1 ;
  • Fig. 3 is an enlarged sectional view of a detail of the washer-drier machine according to an embodiment

  • the washing tank 3 is suitable to contain the washing liquid during the laundry washing steps, and to be a portion of the drying circuit during the laundry drying step.
  • a drain duct 14 is provided with a discharge pump 15 being associated therewith, which provides for the removal of the washing liquid from the tank 3 and controls, together with the supply electrovalves 6, the level of liquid within the tank 3.
  • a coiled electric resistance 11 is provided, which is arranged within the tank 3, particularly on the bottom 13 of the latter, in the gap between the tank wall 3 and the laundry basket 5.
  • the washer-drier machine 1 further comprises a closed-loop drying circuit with a suction unit, for example an fan impeller 17 driven by an electric motor 18, a heat exchanger 10 as well as a heating unit with electric resistance 21, which communicate with each other by means of a drying duct 16.
  • a suction unit for example an fan impeller 17 driven by an electric motor 18, a heat exchanger 10 as well as a heating unit with electric resistance 21, which communicate with each other by means of a drying duct 16.
  • the air flow 22 generated by the suction unit 17, 18 is heated by the electric resistance 21 and blown to the basket 5, where it causes the water contained within the tissues to evaporate as it passes through the wet laundry.
  • the heat exchanger 10 is arranged downstream of the laundry basket 5 (with reference to the direction of the drying air flow 22) and cools the wet air flowing from the basket 5.
  • vapour condensates and is collected and discharged, for example together with a cooling water volume.
  • the dehumidified air is then sucked back by the suction unit 17, 18 and recirculated.
  • the drying circuit further comprises an absorption device 23 suitable to absorb moisture from the drying air 22.

  • the absorption device 23 further comprises heating means 27 arranged in a heat exchange relationship with the zeolite cartridge 26 and suitable to cause moisture to be released from the zeolite cartridge 26 (thermal "regeneration" of the zeolite mineral).
  • the washer-drier machine 1 is thus configured such that, during a drying program, the drying air 22 is conveyed both through the heat exchanger 10 for a dehumidification by means of condensation and through the absorption device 23 for moisture absorption through the zeolite cartridge 26.

Accordingly, any particular reference to the "zeolite" material can be automatically intended as referred to one or more equivalent absorbing and thermally regenerable materials.
  • a first aspect of the invention therefore, provides a washer-drier machine having the characteristics described above and being configured such that the drying air flow is dehumidified by means of two separate dehumidifiers (heat exchanger 10 and absorption device 23) which are the one based on the principle of cooling condensation and the other on the principle of water vapour adsorption.
