Definitions

  • the invention relates to a method for the dehumidification of air in laundry washers, particularly of the domestic type, to be associated to laundry driers emitting to the exterior the warm and humid air used in the drying process.
  • the present invention attains this object of removing the humidity from the drying air by directing the air through suitable conduit means into a rinsing water recovery receptacle installed in the laundry washer, and condensing the humidity contained in this air by making use of the temperature difference between the drying air and the recovered rinsing water.
  • Fig. 2 illustrates an example of a piping system of a laundry washer provided with a receptacle for the recovery of the washing liquid (or rinsing water): the liquid drained from the bottom of a tub 12 is directed through a conduit 13 and a pump 14 to two separate conduits 15 and 16 controlled by respective shut-off valves 17 and 18.
  • Conduit 15 leads to the exterior and acts as the conventional discharge conduit, while conduit 16 opens into the receptacle 5.
  • the two shut-off valves 17 and 18 are controlled by a conventional program control unit not shown in the figure.
  • pump 14 acts to draw the liquid from tub 12 and to deliver it through conduit 13.
  • shut-off valve 17 is open and valve 18 closed. The liquid is therefore directed from conduit 13 to conduit 15 for discharge to the exterior.
  • valve 17 is closed and valve 18 opened.
  • the liquid is deviated from conduit 13 to conduit 16 to flow into receptacle 5.
  • another conduit 20 is provided to connect the top portion of receptacle 5 to discharge conduit 15, this additional conduit 20 being equipped with a non-return valve 21 to prevent the liquid from flowing back into receptacle 5 during a normal discharge phase.
  • This air conduit 3 directs the humid air into a condenser 4 disposed within receptacle 5 itself mounted in laundry washer 1.
  • the outer wall surfaces of condenser 4 are thus in direct contact with the liquid contained in receptacle 5, and preferably provided with cooling ribs for improving the heat exchange effect.
  • the air leaving condenser 4 is finally discharged to the exterior through a discharge conduit 6 and an outlet port 8.
  • conduit 6 The liquid condensed on the walls of condenser 4 collects at the bottom and exits also through conduit 6, the latter being provided with a downwards directed branch 7 disposed at a level below that of outlet port 8 and opening into a condensate collecting receptacle 9.
  • a pump 10 may be provided for directing the collected water through a conduit 11 into receptacle 5.
  • This transfer of the collected liquid may advantageously be completely automatized by the provision of suitable control circuitry for pump 10 which may operate for instance under the direct control of the program control unit, or autonomously by the automatic detection of the liquid level in receptacle 9.
  • the present invention will be recognized to offer a still further advantage: in view of the fact that the air discharged from a laundry drier of the condensation type is never completely dehumidified, the invention is also usefully applicable to the combination of a laundry washer and a laundry drier of the condensation type.
  • a still further improvement and simplification of the described piping system can be obtained in the following manner: by the creation of a partial vacuum within receptacle 5, the condensate collected in receptacle 9 can be automatically transferred from the latter to the former.
  • a partial vacuum of a desired magnitude can be created in a simple manner by the operation of a pump 22 acting to transfer a determined amount of liquid from receptacle 5 into tub 12 through a connecting pipe 23.
  • a further improvement of the described piping system may be achieved by the provision of another connecting pipe 24 connecting condensate receptacle 9 to a top portion of tub 12 in place of pipe 11 discharging into receptacle 5.
