Definitions

  • the present invention relates to a safety device against water pollution for the drying circuit of a washing and drying machine.
  • a washing and drying machine is well-known to include the two functions of washing and drying of clothes.
  • air-gap generally set at 20 mm or more.
  • the object of the present invention is to accomplish an improved safety device against water pollution that can operate effectively and at low cost on the drying circuit of a washing and drying machine, in particular on the supply of cold water destined for the steam condenser.
  • a safety device for the drying circuit of a washing and drying machine comprising a washing container with a rotating laundry drum and a steam condenser communicating with the inside of said container to receive the steam emanated by the washed laundry contained in the drum and housing a nozzle for spraying cold water for the condensation of the abovementioned steam, characterized in that it comprises a pressure switch connected to the steam condenser and calibrated so as to determine the interruption of the supply of water to the spraying nozzle when a level of water is detected in the container that is higher than a predetermined level but lower than the level of supply of said spraying nozzle.
  • a washing container for a washing and drying machine inside which there is rotatably arranged a rotating laundry drum 2 accessible from the outside through a port 3.
  • the drying part comprises a steam condenser 4 constituted by a wide vertical conduit that communicates at its lower end with the inside of the washing container 1 so as to receive the water vapour released by the washed laundry contained in the drum 2 and receives at a height that is selected in an appropriate manner in relation to the level A of the water in the container 1 a nozzle 5 for spraying cold water destined to cause the condensation of the steam in the condenser 4.
  • a steam condenser 4 constituted by a wide vertical conduit that communicates at its lower end with the inside of the washing container 1 so as to receive the water vapour released by the washed laundry contained in the drum 2 and receives at a height that is selected in an appropriate manner in relation to the level A of the water in the container 1 a nozzle 5 for spraying cold water destined to cause the condensation of the steam in the condenser 4.
  • an aspirator 6 constituted by a fan 7 and by a motor 8, that has the task of aspirating the steam to be condensed from the container 1 and that condensed downstream from the nozzle 5 and to send it through a conveyor 9 to a drying area (not shown), where an electrical resistance dries the condensed steam and correspondingly forms a flow of dry hot air that is lastly returned to the container 1 through a recirculation conduit (also not shown).
  • the latter For the supply of cold water to the spraying nozzle, the latter, through a flexible hose 10, is connected to a cold-water mains supply suitably controlled by a solenoid valve that is separate from that used to load the washing water.
  • the dimensions of the bypass 12 are selected so as to avoid any possible clogging up with lint and such like during the drying operation and to make it easy for water to flow back and forth during the washing cycle.
  • a twin pressure switch for the control of other functions, for example to activate the washing machine's discharge pump also protecting a possible breakdown condition of the loading valve at opening or for controlling the level of water for covering the heating resistance, preventing its dry operation.
