Definitions

  • the present invention concerns a device for cooling and condensing the steam formed in the washing vessel of a dishwashing machine.
  • the device includes:
  • a device of this kind is known, for example, from EP-A-486 828 which describes how the steam-laden air is passed over the surface of the cold water at the bottom of the aforesaid chamber in order to dehumidify it.
  • the object of the present invention is to provide a condensation device of the type described at the start of this description, having an effective steam collection.
  • the steam-laden air is forced to pass between two cold surfaces, constituted respectively by the surface of the water in the cavity of a plate and the base wall of the plate above it.
  • the heat exchange is therefore increased to give greater cooling of the air, which causes a more complete condensation of the steam.
  • a dishwashing machine includes ( Figure 1) a washing vessel 10 and a device for cooling and condensing the steam formed therein during operation.
  • a duct 12 connects the vessel to an inlet aperture 14 of a chamber 16 which forms part of the condensation device and will be described in detail below.
  • a plurality of plates 24 arranged substantially horizontally on top of each other is located in the chamber 16 ( Figure 2).
  • Each plate 24 comprises a base part 26 and a side wall 28 to define a cavity 30 housing a plurality of dividing barriers 32 ( Figure 3) which extend substantially transversely with respect to the base wall 26 to subdivide the cavity 30 into a plurality of sub-cavities 33 containing cold water.
  • a narrow space 36 is defined between the base wall 26 of each plate 24 and the upper edge 34 of the side wall 28 of the plate 24 immediately below it.
  • the presence of the barriers 32 avoids the disadvantages that can arise, if the dishwashing machine is not standing on a perfectly flat surface, caused by the uncontrolled pouring of water from the plates 24 and/or the spaces 36 becoming blocked.
  • a first channel 38 within the chamber 16 extends substantially vertically to channel the steam-laden air coming from the aperture 14 into the spaces 36 which extend substantially transversely with respect to the first channel 38, and a second, substantially vertical channel 40 leads from the chamber 16 to the outlet aperture 22.
  • a labyrinthine pathway formed from a plurality of superimposed and offset ribs 41 is interposed between each space 36 and the second channel 40. All of the ribs 41 and, in particular, the bottom rib, are located higher than the upper edge 34 of the side wall 28 at the region where the first channel 38 passes into the associated space 36.
  • the chamber 16 also has, at its top, an aperture 42 for supplying cold water and, at the bottom, a further aperture 44 for the discharge of excess water.
  • the device described above operates as follows.
  • the fan 20 is activated to blow the steam-laden air from the vessel 10 and cause it to flow into the chamber 16 via the duct 12.
  • the air flows along the first channel 38 from which it becomes distributed in the various spaces 36 located substantially transversely with respect to the channel 38.
  • the air cools and the steam condenses.
  • the height of the spaces 36 is preferably less than the height of the side walls 28.
  • the dehumidified air is then channelled into the second channel 40 and output from the chamber 16 via the aperture 22, from which it is returned to the vessel 10 via the second duct 18 in which the fan 20 is located.
  • the pathway through the labyrinths formed by the ribs 41 avoids the water in the cavity 30 of the plates 24 mechanically dragging the air. Such drag is further prevented by the positioning of the ribs 41 of each labyrinth - and, in particular, by the lowermost one - higher than the edge 34 of the side wall 28, in correspondence with the region in which the air laden with moisture enters the associated space 36.
  • the fan can be located either upstream or downstream of the chamber, and the dehumidified air leaving this latter can be discharged directly into the external environment, or can be returned into the washing vessel.
