Definitions

  • the present invention relates to a condensation device, particularly for washing-drying machines.
  • Laundry washing-drying machines with closed-cycle air circulation are washing machines provided with an air circulation device which starts to operate at the end of the washing cycle and of spin-drying and dries the laundry completely.
  • a device wherein the air enters the tank in which the laundry is heated by a radiating element, removes the moisture, passes through the holes of the drum along the discharge ducts, and rises to the fan which pushes the air back into the tank.
  • the air is pushed by a fan into a resistor, where it is heated and fed into the tank which contains the wet laundry.
  • the air becomes moist, is recovered, recycled and, by passing in a condenser which is kept moist and cold by a water jet, releases the moisture.
  • the essential component of these systems is the condenser, in which the air, in contact with the cold water, releases the moisture.
  • Said condenser is normally constituted by a substantially vertical duct, in which the stream of warm and moist air, arriving from below, is struck by a film of water, arriving from above, which causes its cooling and the consequent condensation of the moisture.
  • the water furthermore captures and removes the laundry lint, which is suspended in the drying air and is subsequently disposed together with the waste water.
  • the condensation water jet furthermore washes the walls of the duct which, during operation, tend to become covered with lint.
  • the aim of the present invention is to provide a condenser which can significantly improve heat exchange with respect to known condensers.
  • an object of the invention is to provide a condenser which combines with the preceding characteristic that of further reducing water consumption.
  • Another object of the invention is to provide a condenser wherein the duct can be cleaned easily.
  • a condensation device particularly for washing-drying machines comprising a condensation duct which has a first end and a second end which are connected to a washing and drying tank, which contains the laundry to be dried; a cooling water jet arranged between said ends and directed toward said first end, warm and moist air arriving from said tank being fed into said first end of said duct and escaping from said second end, said jet and said first end defining a condensation section in said duct, characterized in that said condensation section comprises a plurality of mesh members which are arranged substantially transversely inside said duct.
  • a washing-drying machine substantially comprises a tank 2, driven by a motor 3, and an air circulation system, constituted by an aspirator 4 and by a duct 5 which has a first end 6 and a second end 7 which are both connected to the tank 2.
  • the duct 5 comprises: a delivery section 8, comprised between the aspirator 4 and the second end 7 and provided with a heating element 9, and a condensation section 10 comprised between the first end 6 and a nozzle 11 arranged ahead of the aspirator 4.
  • the condensation section 10 is preferably substantially vertical, as more clearly illustrated in Figure 2, and comprises a plurality of mesh members 12, preferably arranged transversely in the duct and in a cascade arrangement, so that the water, arriving from above, forms a succession of films on the various mesh members.
  • Fig. 5 illustrates in detail a mesh member 12 which is constituted by an actual mesh or grid
  • fig. 6 is a view of an element 13 somewhat shaped like a louvered shutter, i.e. constituted by a series of parallel blades.
  • the operation of the device is as follows.
  • the aspirator 4 draws warm and humid air, arriving from the tank 2 which contains the laundry to be dried, through the first end 6 of the duct 5.
  • the nozzle 11 simultaneously generates a small jet of water 13 which turns into a series of waterfalls 14 on the mesh members 12. This causes the forming of films of water on the mesh members 12 which are traversed by the warm and humid air arriving from the tank. This succession of water films facilitates heat exchange and the trapping of the lint present in the air.
  • the permeability of the mesh members causes the continuous separation of the fluff from said elements, which thus remain always clean, optionally with the aid of a device similar to the one described in the above mentioned Italian patent No. 1217490, and European patent application No. 8910333.4.
  • the invention achieves the intended aim and objects by providing a device which can ensure the total cleaning of the condensation duct and at the same time an efficient heat exchange.
  • the device according to the invention has such an efficiency in air-water exchange that the water consumptions can be reduced to one third of normal ones.
  • Another advantage of the invention consists of the absence of maintenance of the mesh members which, since they are self-cleaning due to the fact that the lint is eliminated with the waste water, do not need to be cleaned periodically as occurs in conventional filters.
