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 filter.
- 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.

- the fluff can be removed from the drying circuit, while eliminating the auxiliary pump that is only dedicated to cleaning the heat exchanger filter.
- the electric power consumption for operating the auxiliary pump is also eliminated.
- the fluff-rinse duct 27 is connected to the drying circuit in an upper end portion 32 of the heat exchanger 19, 20 or downstream of the heat exchanger 19, 20 (with reference to the direction of the drying air flow 22) and the primary ducts 19 of the heat exchanger 19, 20 are oriented or inclined such that the fluff-rinse flow 28 passes through these primary ducts 19 countercurrently to the drying air flow 22.
- 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.
- the heat exchanger 19, 20 is arranged between a rear wall 31 of the washing tank 3 and a rear wall of the housing 2.
- a suction opening 30 formed within the lower part of the rear wall 31 of the washing tank 3 connects the interior of the tank 3 to the lower end of the heat exchanger 19, 20, and particularly to the primary ducts 19.
- These primary ducts 19 extend from the bottom up to the upper end portion 32 of the heat exchanger 19, 20, which portion is in flow communication with the suction unit 17, 18 being arranged above the washing tank 3.
- the fluff-rinse flow 28 fed by the spray nozzle 29 in the upper end portion 32 of the heat exchanger 19, 20 passes through the primary ducts 19 from the top down against the direction of the drying air flow 22.
- the fluff-rinse flow 28 cleans the primary ducts 19 and carries the fluff, through the suction opening 30 to the tank bottom 13, from which they are drained together with the fluff-rinse water and condensate.
- the drying circuit is not provided with fluff filters.
- a fluff filter can be arranged upstream of the heat exchanger 19 (with reference to the drying air flow 22) such that the fluff-rinse flow also cleans the filter.

- a further aspect of the present invention relates to conveying the drying flow 22 and cooling flow 26 by means of the respective suction units 17, 18 and 23, 24.
- the suction units for the drying flow and cooling flow can be operated and controlled in an independent manner such as to allow carrying out an independent variation in the flow rate of the individual flows.
- This independent variation in the flow rates of the drying flow 22 and cooling flow 26 is controlled by the same control unit 34 of the washer-drier machine 1 that drives the drying programs and adapts the flow rate of the drying flow 22 to the residual humidity of the laundry and the flow rate of the cooling flow 26 to the ambient temperature.
- the humidity of the laundry can be directly or indirectly detected, and indicatively by measuring the laundry electrical conductivity or by measuring the temperature of the drying flow 22 upstream and downstream of the basket 5 or estimated based on the temperature progress as a function of the time elapsed from the beginning of the drying cycle.
- control unit 34 is configured such as to control and adjust the flow rate of the drying flow 22 and/or the supply of the heating unit 21 as a function of the environment temperature, such as to adapt the drying flow 22 to the heat absorption capacity of the environment in which the washer-drier machine 1 is operating.
- both electric motors 18, 24 are varying speed motors.
- the opening 25 for sucking ambient air is formed in the rear wall 35 of the housing 2 at about the upper end portion 32 of the heat exchanger 19, 20.

- the diagonal tube 41 is inclined relative to the direction of the primary ducts 19 such that the cooling flow 26 blows the surfaces and/or ducts 20 of the heat exchanger 19, 20 in an inclined direction and countercurrently relative to the partial drying flows 22 in the primary ducts 19. This configuration has proved to be particularly effective to the purpose of the air-to-air heat exchange.
- the drying circuit including the first suction unit 17, 18, the heating means 21 and the air-to-air heat exchanger 19, 20 and the cooling circuit, including the second suction unit 23, 24 and excluding the suction opening 25, are all connected to the tank-ballast unit such as to move together with the latter.
- the only flexible connection is that between the suction opening 25 and second suction unit 23, 24.
- the two electrovalves 6, 7 are placed in parallel and supplied by means of an inlet duct 36 in common.
- Each electrovalve 6, 7 has its own outlet duct 37, 38 connected to the detergent tray 12.
- the electrovalves 6, 7 can be controlled independently of each other in order to be capable of selectively opening and closing said outlet ducts 37, 38.
- the detergent tray 12 preferably comprises three compartments, i.e.:
- the outlet ducts 37, 38 of the electrovalve unit 6, 7 are configured and oriented such as to define an intersection point of the flows delivered from the first 37 and second 38 outlet ducts.
- first electrovalve 6 opened and second electrovalve 7 opened three separate flows can be delivered, i.e. a first individual flow in the direction of the first outlet duct 37, a second individual flow in the direction of the second outlet duct 38 and a third crossed flow (with both electrovalves 6, 7 opened) in a resulting direction of the two individual flows in the intersection point.
- two compartments of the detergent tray 12 and the fluff-rinse duct 27 can be supplied in a controlled and independent manner.
- a third compartment of the detergent tray 12, preferably the additive compartment 10 is supplied simultaneously with the fluff-rinse duct 27 for cleaning the heat exchanger 19, 20.
- the flow through the third compartment, e.g. ADD 10 may be branched off from the fluff-rinse flow 28 or vice versa o the third compartment is arranged in series upstream the fluff-rinsing duct 27.
- the common inlet duct 36 has reducing or inlet passing means 39 defining a flow rate max value in this inlet duct 36, e.g. 16 L/min and each of the electrovalves 6, 7 or respective outlet ducts 37, 38 comprises reducing means or outlet passing means 40 defining a max flow rate value in each of these outlet ducts 37, 38 of about half the max inlet flow rate, for example 8 L/min. Consequently, the electrovalves 6, 7 can individually deliver half the max inlet flow rate (for example, 8 L/min) or simultaneously (with both electrovalves 6, 7 opened) a total flow rate equal to the value of the inlet max flow rate (for example, 16 L/min).
- the flow rate of the crossed flow results to be higher than, and more precisely twice the flow rate of the individual flow of each outlet duct 37, 38 with an individual electrovalve opened.
- electrovalve unit which has an inlet flow rate about of 16 L/min and that delivers:
- the common inlet duct 36 has inlet passing means 39A defining the max flow rate value in this inlet duct 36, e.g. 8 litres per minute and each of the electrovalves 6, 7 or respective outlet ducts 37, 38 comprises outlet passing means 40 defining the max flow rate value in each of these outlet ducts 37, 38 approximatively equal to the max inlet flow rate, for example 8 litres per minute.
- the electrovalves 6, 7 can individually deliver the max inlet flow rate (for example 8 litres per minute with an individual electrovalve opened) or simultaneously (with both electrovalves 6, 7 opened) a total flow rate equal to the value of the max inlet flow rate (for example 8 litres per minute).
- each outlet duct would deliver a flow of about half (e.g. 4 litres per minute) the max inlet flow rate (e.g. 8 litres per minute).
- the f low rate of the crossed f low results about equal to the flow rate of the individual flow of each outlet duct 37, 38 with an individual electrovalve opened. This would allow using the same electrovalve units as already used in the washing machines without drying function.
- control unit is configured such as to allow selecting a drying program having three steps (an early heating step, a subsequent operating temperature and a subsequent final cool down step), wherein:
