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.
  • the 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 humid air is cooled by a cold water flow. Due to this cooling action, 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).
  • EP 1698722 A1 discloses for instance a washing machine requiring a first water supply valve and an additional three-way water sypply valve and a controller which must handle four distinct valve ON-OFF situations.
  • the object of the present invention is thus to provide a washer-drier machine having such characteristics as to reduce the number of hydraulic components and to simplify the structure thereof.
  • the washer-drier machine comprises:
  • FIG. 1 is a side sectional view of a washer-drier machine according to an embodiment of the invention
  • FIG. 2 is a front sectional view of the washer-drier machine in Fig. 1 ;
  • Fig. 3 , 4 , 5 are top schematic views illustrating the mains water supply system to the tank and heat exchanger according to several embodiments of the invention.
  • 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 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 electrovalve 6, 7.
  • 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 16 is provided, which is arranged within the tank 3, particularly on the bottom of the latter, in the gap between the tank wall 3 and the laundry basket 5.
  • the washer-drier machine 1 further comprises a drying circuit with a suction unit, for example a fan impeller 17 driven by an electric motor 18, a heat exchanger, for example a condensation chamber 19 with a spray nozzle 20 suitable to spray or atomize cooling water within the condensation chamber 19, as well as an electric-resistance heating unit 21 which communicate with each other by means of a drying duct 16.
  • a suction unit for example a fan impeller 17 driven by an electric motor 18, a heat exchanger, for example a condensation chamber 19 with a spray nozzle 20 suitable to spray or atomize cooling water within the condensation chamber 19, as well as an electric-resistance heating unit 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 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 19, 20 is arranged downstream of the laundry basket 5 (with reference to the direction of the drying air flow) and cools the wet air blowing from the basket 5, for example by means of the atomized cold water, either dripped or sprayed.
  • vapour condensates and is collected and discharged together with the cooling water.
  • the de-humidified air is then sucked again by the suction unit 17, 18 and ricirculated.
  • the heat exchanger 19, 20 is supplied with cooling water 22 by means of a cooling duct 23, which branches off from one of the washing flow paths, such that the heat exchanger 19, 20 can be selectively supplied by means of the first 6 and second 7 electrovalves (in some instances together with the washing flow path from which the cooling duct 23 branches off).
  • the electrovalve only dedicated to the heat exchanger can be eliminated and the electrovalve control can be simplified.
  • Fig. 3 shows an embodiment of the invention in which the detergent tray 12 comprises two compartments, i.e.:
  • a first base duct 24 extends from the first electrovalve 6 to a intersection point 26, preferably aligned with a central partition wall between the LAV 9 and ADD 10 compartments of the detergent tray 12 and a second base duct 25 extends from the second electrovalve 7 to the same intersection point 26.
  • the outlet ends and openings of the first base duct 24 and second base duct 25 in the intersection point 26 are oriented such that:
  • the first base duct 24 and second base duct 25 supply a crossed mains water flow through the compartment ADD 10 in the washing tank 3.
  • This embodiment is a simplification of the water supply and condensation circuit layout and provides for example that the pre-washing detergent is directly loaded within the tank.
  • the water is loaded to the tank to determine the lye level for the pre-washing cycle, while carrying out a cleaning operation of the heat exchanger.
  • the heat exchanger 19, 20 can be thus selectively supplied with mains water by the first electrovalve 6 being opened and the second electrovalve 7 being simultaneously closed.
  • a residual amount of water is conveyed through the ADD compartment 10 of the tray 12 to the washing tank from which it can be drained, for example, together with the condensed water flowing from the condensation chamber 19.
  • the flow rate ratios of the cooling duct 23 to the washing flow path through the ADD compartment 10 can be set by suitably selecting the respective flow resistances within these ducts.
  • Fig. 4 illustrates a further embodiment of the invention, wherein the detergent tray 12 comprises three compartments, i.e.:
  • a first base duct 24 extends from the first electrovalve 6 to a intersection point 26 at the middle LAV compartment 9 of the detergent tray 12 and a second base duct 25 extends from the second electrovalve 7 to the same intersection point 26.
  • the cooling duct 23 is hydraulically connected and substantially axially aligned with the first base duct 24. Furthermore, the cooling duct at least partially extends above the ADD compartment 10 and an opening 28 is formed on the bottom of the cooling duct 23 through which a portion of the cooling flow is supplied to the ADD compartment 10 and from the latter to the washing tank 3.
  • the outlet ends and openings of the first base duct 24 and second base duct 25 in the intersection point are oriented such that:
  • the first base duct 24 supplies a mains water flow only to the cooling duct 23 from which a flow portion is sent to the ADD compartment 10 of the detergent tray 12 and from the latter to the washing tank 3;
  • the first base duct 24 and second base duct 25 supply a crossed mains water flow in a resulting central direction substantially only through the compartment LAV 9 to the washing tank 3.
  • the present invention ( Fig. 4 ) advantageously allows maintaining a three-compartment detergent tray without increasing the number of electrovalves.
  • the pre-washing water and detergent are loaded to the tank in order to determine the level of lye for the pre-washing cycle.
  • an intermediate compensation tray 34 is arranged between the opening 28 of the duct 23 and the ADD compartment 10.
  • This compensation tray 34 can be in flow communication with the washing tank and delivers at least one part of the water to the ADD compartment 10 only when a determined water level has been reached. This allows either including or excluding the ADD compartment 10 from the flow path, according to the duration of the opening time of the first electrovalve 6.
  • the heat exchanger 19, 20 can be selectively supplied with mains water by the first electrovalve 6 being opened and the second electrovalve 7 being simultaneously closed.
  • a residual amount of water is conveyed through the ADD compartment 10 of the tray 12 or, alternatively, through the compensation tray 34, to the washing tank from which it can be drained, for example together with the condensed water flowing from the condensation chamber 19.
  • the flow rate ratio of the cooling duct 23 to the washing flow path through the ADD compartment 10 and/or compensation compartment 34 downstream of the branching-off point can be set by suitably selecting the respective flow resistances within these ducts and paths.
  • Fig. 5 illustrates a further embodiment of the invention, in which the detergent tray 12 comprises three compartments, i.e.:
  • a first base duct 24 extends from the first electrovalve 6 to a intersection point 26 that is arranged substantially aligned with a partition wall 29 separating the middle PRE compartment 8 from the side compartment LAV 9 of the detergent tray 12.
  • a second base duct 25 extends from the second electrovalve 7 to the same intersection point 26.
  • the cooling duct 23 is hydraulically connected to both base ducts 24, 25 and substantially axially aligned with a resulting direction of a crossed water flow of the two base ducts 24, 25.
  • crossed flow is meant the vector addition of the two mains water flows that are simultaneously supplied by the first base duct 24 and second base duct 25 at the intersection point 26.
  • the cooling duct 23 at least partially extends above the ADD compartment 10 and an opening 28 is formed on the bottom of the cooling duct 23 through which a portion of the cooling duct is supplied to the ADD compartment 10 and from the latter to the washing tank 3.
  • the outlet ends and openings of the first base duct 24 and second base duct 25 in the intersection point 26 are oriented such that:
  • the first base duct 24 supplies a mains water flow, preferably through a first intermediate channel 30, only to the PRE compartment 8 and from the latter to the washing tank 3;
  • the second base duct 25 supplies a mains water flow, preferably through a second intermediate channel 31, only to the LAV compartment 9 and from the latter to the washing tank 3;
  • the first base duct 24 and the second base duct 25 supply a crossed mains water flow in a central resulting direction only to the cooling duct 23 from which a flow portion is sent to the ADD compartment 10 of the detergent tray 12 and from the latter to the washing tank 3;
  • the pre-washing water and detergent are loaded to the tank in order to determine the level of lye for the pre-washing cycle.
  • the washing detergent is loaded to the tank to carry out the main washing cycle, and with both electrovalves 6, 7 opened, the additives are loaded to the washing tank, while carrying out a cleaning operation of the heat exchanger.
  • the heat exchanger 19, 20 can be selectively supplied with mains water by the first electrovalve 6 and second electrovalve 7 being simultaneously opened.
  • An amount of residual water is conveyed through the ADD compartment 10 of the tray 12 to the washing tank 3 from which it can be drained, for example, together with the condensed water flowing from the condensation chamber 19.
  • the flow rate ratios of the cooling duct 23 to the washing flow path through the ADD compartment 10 downstream of the branching-off point can be set by suitably selecting the respective flow resistances in these ducts and paths.
  • this flow rate ratio of the cooling duct 23 to the washing flow path through the ADD compartment 10 is selected such that the amount of liquid passing through the ADD compartment ADD 10 is barely enough to convey the additive from the detergent tray 12 to the washing tank 3.
  • the intersection point of the base ducts 24, 25, any intermediate channel, and the compartments of the tray 12 are shaped and positioned such that, with the first and second electrovalves opened, at least one first portion of the resulting crossed flow is supplied to the LAV compartment 9 and to the PRE compartment 8.
  • a small water counter-flow can be provided along one or more walls of the washing tank 3 which is suitable to remove the yarns carried by the drying air flow and deposited onto the walls of the washing tank 3.
  • the condensation unit of the drying circuit comprises, in addition to the spray heat exchanger 19, 20, a further heat exchanger provided by a cold water free surface 32 that is collected and held on the bottom of the washing tray 3.
  • the drying program of the washer-drier machine 1 is configured such as to hold the cold water free surface 32 at a safety distance from the basket and to drain the water on the tank bottom, by means of the discharge pump 15, as a function of the level and temperature of the water 32. Thereby, the heating of the cold water on the bottom of tank 3 as well as the increased level due to the formation of condensate are taken into account.
  • the volume of cold water 32 on the bottom of the washing tank 3 can be loaded by means of one of the washing flow paths through one or more of the compartments of the detergent tray 12. Thereby, and due to the cooling duct 23 branching off from one of the washing flow paths, the spray heat exchanger and the free condensation surface on the bottom of tank 3 can be supplied independently from each other.
  • the washer-drier machine according to the invention has a number of advantages.
  • a double result is obtained of effectively cooling the drying air and eliminating the yarns deposits on the washing tank walls by means of a counter-flow that takes place automatically and simultaneously with the mains water supply to heat exchanger.
