Definitions

  • the present invention relates to a domestic washer-drier machine which provides for washing and drying the laundry.
  • 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 housed rotatably about an 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.
  • This washing water delivery system comprises a plurality of electrovalves suitable to selectively adjust the supply to a plurality of flow paths extending downstream of these electrovalves through respective compartments of a detergent tray to the washing tank.
  • 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.
  • 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 a suction 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 suction 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 humid air is cooled by a cold water flow. 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 suction unit and ricirculated.
  • This known solution entails, besides high electric power consumption, a non negligible water consumption, in the order of 40 - 50 L per drying cycle.
  • Washer-drier machines are further known, which carry out only the function of drying the laundry.
  • these washer-drier machines cool the heat exchanger by means of a second cooling air flow from the environment, the so-called air-to-air heat exchange.
  • the fluff is automatically captured by the cooling water and eliminated through the drain duct.
  • filters are provided to be arranged in the drying circuit downstream of the laundry basket and upstream of the heat exchanger. These filters are usually accessible through the loading door to allow cleaning and replacing the same, when required.
  • a filter in a washer-drier machine having circuits and washing liquid levels that are configured such as to meet the washing requirements requires a reduction in the filter bulk, which filter has to be placed in a dry area that can be easily reached by the user for cleaning and replacement purposes. This entails an increase in the flow resistance with a consequent increase in the power required to achieve a predetermined drying air flow rate.
  • EP 0 816 549 A1 has suggested a washing machine with an air-to-air heat exchanger and a large-sized self-cleaning fluff trap.
  • an auxiliary duct branches off from the drain duct of the washing tank and a suitable auxiliary pump conveys a part of the washing or rinse liquid drained from the tank, through this auxiliary duct and a suitable sprinkler nozzle to the filter in order to perform cleaning.
  • this solution entails high manufacturing costs, as well as the provision of a drying program which provides for a dedicated driving operation of the auxiliary pump.
  • the general object of the present invention is thus to provide a washer-drier machine that is provided with an air-to-air heat exchanger, having such characteristics as to overcome at least some of the drawbacks found when the air-to-air condensation technology is transferred from the drying machine to the washer-drier machine.
  • a further object of the present invention is to reduce the hydraulic components of the washer-drier machine and the electric power consumption to eliminate the fluff within the drying circuit.
  • the washer-drier machine for washing and drying the laundry comprises:
  • the auxiliary pump is eliminated, and the network pressure is used in order to remove the fluff from the drying circuit, the electric power consumption to operate the auxiliary pump are also eliminated.
  • FIG. 1 is a side sectional view of a washer-drier machine according to an embodiment of the invention

  • Fig. 3 is a further partially sectional side view on a different sectional plane from that in Fig. 1 .
  • FIG. 4 is a partially sectional top view of the washer-drier machine in Fig. 1 ;
  • FIG. 5 schematically illustrates a detergent tray with the respective washing flow paths and with the electrovalve unit of a washer-drier machine associated therewith according to a further embodiment of the invention
  • FIG. 6 schematically illustrates a detergent tray with the respective washing flow paths and with the electrovalve unit of a washer-drier machine associated therewith according to a further embodiment of the invention

  • a basket 5 is rotatably housed about a horizontal or inclined axis, for the laundry to be accommodated therein to be washed and/or dried.
  • the basket 5 also defines a front opening that is located such as to match the opening of the washing tank 3, in order to be capable of carrying out the loading/unloading of the laundry.
  • 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 washing water delivery system that can be connected to the water supply is provided in order to load the tank 3 with mains water and detergent substances and aids.
  • This washing water delivery system comprises a plurality of washing flow paths extending from, for example, first 6 and second 7 supply electrovalves, through corresponding compartments 8, 9, 10 of a detergent tray 12, to the washing tank 3.
  • the washing flows along the washing flow paths can be selectively adjusted by means of the first and/or second electrovalves 6, 7.
  • a drain duct 14 is provided with a discharge pump 15 being associated thereto, which provides for the removal of the washing liquid from the tank 3 and controls, together with the supply electrovalves 6, 7 the level of liquid within the tank 3.

  • the first suction unit 17, 18 is arranged upstream and preferably above the connection of the fluff-rinse duct 27 such that the fluff-rinse flow 28 only involves the heat exchanger 19, 20 and not the fan impeller 17.
  • means are provided to deliver the fluff-rinse flow 28, such as a spray nozzle 29 configured to deliver the fluff-rinse liquid on all the primary ducts 19 of the heat exchanger 19, 20, and possibly, to increase the pressure therein.
