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 is provided to be connected to the water system.
  • This washing water delivery system comprises a plurality of electrovalves which are 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 with a discharge pump being associated thereto On the bottom of the washing tank there is provided a drain duct with a discharge pump being associated thereto, which provides for the removal of the washing liquid from the tank and controls, together with the supply electrovalves, the liquid level within the tank.
  • an electric resistance is provided, which is arranged within the tank in the gap between the tank wall and the laundry basket.
  • a drying circuit of prior art washer-drier machines typically comprises a suction unit, a heat exchanger and a heating unit with electric resistances intercommunicating by means of a drying circuit.
  • the air flow generated by the suction unit is heated by the electric resistances and sent to the basket, where it flows through the wet laundry thereby causing the water contained in the fabric to evaporate.
  • 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 de-humidified air is then sucked again by the suction unit and ricirculated.
  • 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 in the heat exchanger (condenser).
  • the production cost of the washer-drier machines result to be further increased by the difficulty or impossibility of using the large-scale components that are manufactured for washing machines.
  • the object of the present invention is to provide a washer-drier machine having such characteristics as to overcome at least some of the problems mentioned with reference to the prior art.
  • the washer-drier machine comprises:
  • the lid comprises a system of cavities that are suitable to contain the cooling water, namely a cooling coil that can be supplied with mains water such that the lid forms a condensation wall.
  • the suction duct is formed by the tank wall and by a lid that is manufactured separately and then connected to the tank wall, the same washing tank (with and without lid, respectively) can be used both for manufacturing washing machines and for manufacturing washer-drier machines.
  • the lid with a system of cavities to contain the cooling water, the traditional atmospheric condenser separated from the tank can be eliminated and the overall structure of the washer-drier machine can be simplified.
  • the system of cavities i.e. the lid cooling coil, is arranged in the washing water supply path, preferably in series between the supply electrovalve and a detergent tray and can be supplied by means of the same washing water supply circuit.
  • a washer-drier machine 1 comprises a support and housing structure 2, a washing tank 3 being housed therein, which is provided with a front opening that can be closed by means of a porthole door 4 being hinged in the front of the housing 2.
  • a basket 5 is pivotally 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 load/unload 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 is provided to be connected to the water system.
  • This washing water delivery system comprises a plurality of washing flow paths extending from, for example, two supply electrovalves 6, 7, through corresponding compartments 8, 9, 10 of a detergent tray 12, to the washing tank 3.
  • a drain duct 14 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.
  • 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 as well as a heating unit with electric resistance 21, which communicate with each other by means of a drying circuit 16.
  • a closed-loop drying circuit with a suction unit for example an fan impeller 17 driven by an electric motor 18, a heat exchanger as well as a heating unit with electric resistance 21, which communicate with each other by means of a drying circuit 16.
  • the air flow 22 generated by the suction unit 17, 18 is heated by the electric resistance 21 and sent to the basket 5, where it flows through the wet laundry thereby causing the water contained in the fabric to evaporate.
  • the heat exchanger 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 volume of cooling water.
  • the de-humidified air is then sucked again by the suction unit 17, 18 and ricirculated.
  • the drying circuit 16 comprises a tubular suction duct 26 formed of a wall portion 27 of the washing tank 3 and of a lid 28 that is manufactured separately and then connected to the wall portion 27.
  • the lid 28 comprises a system of cavities that are suitable to contain the cooling water, namely a cooling coil 29 that can be supplied with mains water such that the lid 28 forms a condensation wall.
  • this suction duct 26 extends within the washing tank 3 from a lower area thereof to an opening 30 in the upper area thereof and is defined by a portion of the inner surface of the tank 3 and by the lid 28.
  • the same washing tank 3 can be advantageously used both with washing machines without drying function (without the inner lid 28), and with drier-washer machines (with the inner lid 28). Furthermore, as the lid 28 forms a condensation wall, two condensation surfaces are obtained, i.e. the inner surface 31 and the outer surface 32 of the lid 28, which are both arranged within the washing tank 3 and blown by the drying air 22.
  • the cooling coil 29 can be supplied with mains water and arranged in the washing water supply path, between the supply electrovalve 6, 7 and the washing tank 3, preferably upstream of the detergent tray 12.
  • the cooling coil 29 is supplied by means of the same washing water supply circuit. This allows the elimination of a dedicated supply circuit for supplying the cooling coil 29 as well as a simplification of the control programs driving the supply electrovalves.
  • the lid 28 is made from plastics and the cooling coil 29 is formed by means of blow moulding at or in the lid 28.
  • the lid 28 made of plastics can be used both with a metal washing tank (e.g. stainless steel) and with a washing tank made of plastics by means of moulding.
  • the cooling coil 29 cannot be emptied. By opening the supply valve 6, 7, the water contained within the cooling coil 30 can be only replaced with fresh mains water.
  • the lid 28 is removably connected to the washing tank 3, such as to allow the same to be replaced in the event of damage, for example limestone clogging.
  • the washing tank 3 defines therein and upstream of the suction duct 26 (with reference to the direction of the drying air flow 22) a condensation space 19 that is suitable to contain a volume of cooling water 20 that forms a surface of free water and spaced away from the basket 5 such as to be capable of cooling the drying air flow 22 downstream of the basket 5 and upstream of the suction duct 26 within the washing tank 3.
  • the free water surface is an additional condensation surface to those provided by the lid 28.
  • the condensation space 19 is formed at the tank bottom 13, approximatively below the basket 5.
  • This further condensation surface also does not require any dedicated supply circuit, because the water volume 20 (condensation surface) on the bottom of the washing tank 3 can be easily supplied with the mains water that is loaded by means of the washing water loading circuit.
  • the volume of cooling water 20 on the tank bottom 13 also allows a continuous use of a same water volume until the latter is heated past a threshold temperature allowed for condensation purposes. This results in a considerable saving of cooling water during the drying step.
  • the washer-drier machine 1 comprises a control unit (not shown in the drawings) that is configured such as to cause the discharge pump 15 and supply electrovalves 6, 7 to drain and/or replace the cooling water within the coil 29 of the lid 28 and/or the cooling water volume 20 on the tank bottom as a function of the temperature of the cooling water and/or as a function of the level of the mixture of cooling water 20 and condensate on the tank bottom 13.
  • the control unit interacts with suitable pressure or level sensors 24 that are arranged at the tank bottom 13 and one or more temperature sensors 25 that are arranged in direct or indirect thermal contact with the cooling water within the lid 28 and/or on the tank bottom 13.
  • control unit is configured such as to cause the discharge pump 15 and supply electrovalves 6, 7 to drain and/or replace the cooling water within the coil 29 of the lid 28 and/or the cooling water volume 20 on the tank bottom at predetermined time intervals, such that:
  • control unit is preferably configured such as to allow selecting a drying program, in which, during an early drying step, only the first heat exchanger will be operated, whereas the condensation space 19 on the tank bottom 13 will be not provided with cooling water 20.
  • the washer-drier machine according to the invention has a number of advantages.
  • the suction duct being formed by the wall portion of the washing tank 3, and the lid 28 being manufactured separately and then connected to the wall portion, the same tank structure can be used both for washing machines and washer-drier machines.
