Definitions

  • the present invention relates to a closure device for the door of a dishwasher comprising a body, a washing chamber in which there is disposed at least one rotatable drum electrically operated members in particular a heater element and a washing pump, water directing members and a door for closure of the washing chamber.
  • the object of the present invention is that of overcoming the said disadvantages and providing a door closure device for a dishwasher in which the safety switch is mounted on the body of the dishwasher, the opening and closing movements of the dishwasher will be “soft", and in which if the door is opened with the machine in operation there will first be an interruption of the mains electricity supply and then release of the door.
  • a door closure device for a dishwasher comprising a body, a washing chamber in which there is disposed at least one rotatable drum, electrically operated members and particularly a heater element and a washing pump, means for directing the water within the machine and a door for closure of the washing chamber, characterised by the fact that the said device includes mechanical means disposed in part on the door and in part on the body of the dishwasher, and electrical means for enabling and disabling the said electrically operated members and disposed solely on the body of the dishwasher itself.
  • the striker 3 also has a switch support 7, which is also formed with two cylindrical projections 8 and 9. Over the first projection 8 is fitted one end of a biasing spring 10 the other end of which is fitted over a cylindrical projection 11 of the striker support 6 which is positioned in correspondence with the cylindrical projection 8 of the switch support 7. Over the cylindrical projection 9 of the switch support 7 there is fitted a safety switch 12 the electrical terminals of which are connected in series to the mains supply of the machine through its reference hole 13 and which is then fixed to the said switch support 7 by means of a screw 14.
  • the safety switch 12 has a plunger 15 which has a stroke of 1.5 mm between opening and closing its electrical contacts.
  • a fixed handle 20 which has holes both to allow passage of screws for fixing the latch block 18 to the door 19 and to allow passage of a finger member 21 rigidly connected to a movable handle 22 which transmits upward movement exerted by the user on the movable handle 22 to the free end of the striker 3.
  • the movable handle 22 is pivoted to the door 19 in a known way and in such a way that it can turn about its pivot axis 23.
  • the form of the end of the striker 3 and of the latch block 18 in the region of the f in- ger member 21 is such that in the event of knocks against the door 19 such ends touch one another so that the striker 3 contacts against the latch block 18 preventing any damage to the probe member 16 which could become sheared off, since, as already mentioned, having to pass through the hole 17 which for reasons of security must be small, it too is of reduced dimensions.
  • the striker 3 continues to rise and after a stroke of 4 mm.
  • the free end of the striker 3 is located in a region overlying the part of the latch block 18 which supports the probe 16 and from this moment there is no longer any impediment tying the door 19 and the body 1 of the machine together, and the door 19 can open without further obstacle.
  • the part of the latch block 18 which supports the probe 16 touches the lower free end of the striker 3 making it rise above the rest position in such a way that the probe 16 can pass without interfering with the striker 3; at this point the biasing spring 10 (which is preloaded under compression) makes the striker 3 turn to its rest position holding the door 19 closed, whilst the probe 16 compresses the plunger 15 of the safety switch 12 enabling the supply to reach the electrical members of the machine.
  • the said spring 10 must overcome the friction and the closure force of the plunger 15 which is equivalent to about 500 grammes and given that it works in a plane parallel to the closure plane of the door 19 it is sufficient that it can balance a load of about 1 kg. More or less the same load is sufficient for the user to open or close the door 19 and therefore the opening and closure operation of this door 19 will be "very soft".
