Definitions

  • the present invention relates to a water-saving device for washing-drying machines.
  • Machines termed washing-drying machines with closed-cycle air circulation which comprise an air circulation device which starts to operate at the end of the washing cycle and after spi -drying, for drying the laundry completely.
  • the air enters the tank, where the laundry is heated by a radiating element, removes the moisture, passes through the holes of the drum along the discharge ducts, and then rises up to the fan, which pushes the air back into the tank.
  • the air by passing through the warm laundry, removes the moisture and, by passing through the discharge duct, makes contact with the cooling water and consequently deposits the moisture. This cycle is repeated for approximately 100-120 minutes until the laundry is perfectly dry.
  • the air is pushed by a fan in contact with a resistor which heats it.
  • the air is then fed into the drum, where, in contact with the wet laundry, it becomes loaded with moisture.
  • This moisture-rich air then passes in a condenser, which is kept humid and cold by a jet of water, and deposits the moisture inside said condenser.
  • the condenser is generally constituted by a substantially vertical duct, wherein the current of warm and moist air coming from the lower end is intercepted by a film of water co ing from the upper end.
  • the film of water cools the warm air causing the condensation of the moisture.
  • the water also captures ' and removes the fluff, which has deposited on the duct walls. This fluff is then disposed of together with the discharge water.
  • the water thus acts as cooling means and as means for washing the condensation ducts in known drying systems.
  • the aim of the present invention is to provide a washing- drying machine which has a considerably lower water consumption than known machines.
  • a water-saving device for washing-drying machines which comprises a condenser element connected t the tank of the machine, aspirator means connected to said condenser so that the moist air which is present in said tank is fed into said condenser and subsequently fed into said tank, characterized in that it comprises a cooling duct arranged adjacent to said condenser element, and ventilation means adapted to generate a flow of air in said cooling duct so as to cool said condenser in order to condense the moisture of said air fed into said condenser.
