Definitions

  • the present invention refers to a combined automatic machine adapted to wash and/or dry clothes.
  • Such combined machines which are generally known under the term of washer-driers in the art, are largely known to mainly comprise a tub adapted to contain, usually inside a rotating drum, clothes that can be washed, rinsed, spin-extracted and/or dried thanks to the provision of appropriate water-carrying circuits, as well as a drying circuit by means of which heated air that becomes progressively laden with the moisture subtracted from the clothes contained in the tub is caused to circulate through or in correspondence of condenser means for the condensation of said moisture.
  • the above cited water-carrying circuits comprise a dispenser of washing and/or rinsing products, which may for instance be in the form of a pull-out drawer, or the like, and is arranged so as to be able to be supplied from one or more nozzles with water adapted to flush off said washing and/or rinsing products and convey them into the tub through a siphon arrangement.
  • a dispenser of washing and/or rinsing products which may for instance be in the form of a pull-out drawer, or the like, and is arranged so as to be able to be supplied from one or more nozzles with water adapted to flush off said washing and/or rinsing products and convey them into the tub through a siphon arrangement.
  • Residual water collects on the bottom of said siphon so as to cut off the communication existing between the tub and said washing product container, thereby preventing, for instance during the clothes drying phase, the moisture-laden hot air that is present in the tub from leaking into the outside ambient through the same product container.
  • Such an undesired occurrence of the siphon emptying out may for instance be brought about by water losses caused by the oscillations of the machine during a spin-extraction phase of the clothes washing cycle and/or by the evaporation of the residual water contained in the siphon owing to the heating which the same water is exposed to during certain operation phases of the machine, in particular during the clothes drying process.
  • a combined clothes washing and drying machine mainly comprises a washing tub 10, within which there is rotatably mounted a drum 11 that is adapted to hold the clothes to be washed and dried.
  • the machine further comprises a container or dispenser 12 provided with compartments for holding and dispensing the washing and rinsing products and aids, which are capable of being selectively supplied with the water flowing in from the mains 13 via electromagnetic valves 14, 15.
  • the water from the mains then flows from the dispenser 12 into the tub 10 via a pipe 16 in which there is included a siphon-shaped portion 17.
  • This siphon-shaped portion 17 collects residual water so as to normally form a hydraulic stoppage which prevents the moisture-laden air that is present in the tub 10, in particular during the clothes washing and drying phases of the operating cycle, from leaking into the outside ambient through the pipe 16 and the dispenser 12.
  • the machine is provided with a condenser 18 which is connected to the tub 10 within a circuit that also comprises air circulating means 19 and air heating means 20.
  • the moisture-laden hot air is taken from the interior of the tub 10 and is cooled down in the condenser 18 by means of cold water flowing in from the water supply mains 13.
  • the cold water used to condense the moisture subtracted from the clothes is delivered to the condenser 18 via an additional water-carrying circuit 21 which reaches the condenser 18 by starting from the lint filter 22 included in the water discharge circuit of the machine, which comprises also a drain pump 25.
  • the condensation circuit 21 there is included a circulating pump 23.
  • the water needed to condensation purposes is taken from the water supply mains 13 by actuating the electromagnetic valves 14 and/or 15 in a pulsating, i.e. recurrent manner, so as to be able to let into the tub 10, via the conduit 16 and the siphon 17, a minimum amount of water which is then recirculated from the tub to the condenser and vice-versa.
  • this valve is actually replaced by an electromagnetic valve 15 which is intended to perform a plurality of functions, that is to first of all let the washing and/or rinsing water into the tub and, then, to supply the cooling water to the condenser for moisture condensation purposes and, by the way, to automatically provide that amount of water which is needed to perform as a "stopper" in the siphon 17, as this has already been described above.
  • the drain pump 25 turns out to be far less stressed, owing to the fact that condensate water is discharged periodically and not continuously.
  • Such an elimination of the electromagnetic valve to supply water to the condenser, and the replacement of such a valve with a recirculation pump, enables the likelihood of occurrence of failures or breakdowns to be reduced, since an electromagnetic valve is a by far more delicate component part than a small-capacity pump.
  • the condenser is effectively protected against lint being capable of settling down in the condenser itself, thereby doing away with a major cause of condenser malfunction.
  • the recycling circuit 30 includes a recycling pump 31 and, preferably, part of the filter situated in the lower portion of the machine, under the tub, and it reaches up to the upper portion of the tub. It should be noticed that the remaining reference numerals in Figure 4 are the same as those used in Figure 3 to indicate those component parts that are present also in the machine illustrated in said Figure 3.
  • the pump 23 for the recirculation of the condenser cooling and condensate water and the pump 31 for the recirculation of the washing/rinsing water are mounted in a mutually aligned arrangement on a same conduit 32 extending from the filter 22; in particular, said recirculation pump 31 is provided on a conduit 32A that comes from said condensate and cooling water pump 23.
