Definitions

  • the present invention relates to washers/dryers, and in particular to a condensing unit for drying the laundry at the end of the washing cycle.
  • a fan During the drying phase a fan generates an air stream in the circuit and a resistor heats the air circulating in said circuit.
  • an electrovalve is opened to admit condensing water into a condensing duct, where the condensing water is kept in suspension by the suction generated by the fan.
  • the vapour sucked in from the tank encounters the suspended water and partially condensates toward the drain pump through a suitable drain pipe. Therefore, the fan receives partially cooled and dried air that is heated again by the resistor and returned to the tank.
  • the object of the present invention is to provide a condensing unit which overcomes said drawbacks. This object is achieved by means of a condensing unit that realizes a counter-current heat exchanger with a flat and elongated cross-section. Other advantageous features of the present condensing unit are disclosed in the dependent claims.
  • this condensing unit greatly increases the thermal exchange surface for the moist air coming from the tank, so as to improve the condensing effectiveness. This results in a decrease of the drying time, with a subsequently lower power consumption.
  • Another significant advantage of this arrangement comes from its structural compactness that allows to realize a unit shaped so as to exploit areas of the machine that would otherwise be unused, thus reducing the overall size of the machine.
  • a washer/dryer includes a tank T, closed by a door P, that houses a rotating drum D containing the laundry L to be dried.
  • the drying circuit conventionally includes a fan F and a resistor R to heat the air prior to returning it to tank T through a suitable duct H.
  • the novel aspect of the present invention consists of the condensing unit C, that includes a condensing duct made up of an air channel A and a water channel W divided by a thermal exchange surface E. More specifically, the stream of moist air, coming from tank T under the action of fan F, flows in a direction opposite to the stream of condensing water, introduced at the top of channel W through an electrovalve (not shown), and the separation of the two streams is performed by means of the dividing wall E that acts as a heat exchanger where moisture condensates.
  • the moisture condensated on wall E flows downward by gravity along channel A and is discharged by the drain pump (not shown), together with the condensing water coming from channel W.
  • the front view of fig.3 shows a condensing duct that is horseshoe-shaped so that it can be arranged in the rear portion of the machine around the mechanism that rotates drum D, typically a pulley driven by a motor through a belt, or directly a motor.
