Definitions

  • This invention is concerned with a push-button device for opening the port-hole shaped door in domestic washing machines.
  • Port-hole door opening devices have already been provided using a push-button located on the machine control panel.
  • This approach is certainly an improvement concerning the aesthetic appearance, but it requires a moving slider adapted to connect the push-button device to the latching members, and this largely complicates the construction of the machine, with associated cost drawbacks, besides having a negative influence on the safety required against accidental openings of the port-hole door.
  • the device according to this invention is characterized by a push-button device, built into the port-hole door latching assembly, and mounted on the front wall of the machine, close to said port-hole, and provided towards the inside with a movable body having a sloping flat surface adapted to engage a corresponding surface of a movable slider which normally retains the port-hole door closing latch, in order to free said latch for opening said port-hole door.
  • push button 1 according to this invention is mounted in a built-in arrangement on the latching assembly of port-hole door 5, as it is shown in Figures 2 and 3, in order to be actuated from outside on the machine front wall 7, in a position close to said port-hole 5.
  • the general arrangement obtained is simple and straightforward, as it is presently required in modern machines, where as far as possible an attempt is made to render as unconspicuous as possible the front panel controls, even reducing the number thereof.
  • port-hole door 5 of a washing machine is kept locked in a closed position, with peripheral rubber ring 9 acting as a seal, through engagement of a latch 4, hinged at one end, onto the metal ring 5a which surrounds port-hole 5. Engagement takes place with a corresponding stop portion in an area 2 of door-latching and -locking, located near port-hole door 5 on the inner side of wall 7.
  • Push button 1 is then located immediately between said latching and locking area 2 and a part 3 including the door-locking electrical components.
  • latch 4 is pushed into engagement with portion 2 by a slider 6 normally kept in a closed position by a pawl (not shown), which is actuated when the machine is switched on.
  • a pawl not shown
  • the components of door lock 3 are supplied with an electrical voltage and one among them, i.e. a thermistor, rapidly reaches its thermal stabilization temperature thereby heating the bi-metallic couple it is lying upon and whose mechanical distortion causes the electrical closure of a microswitch which in turn supplies power to the electro-mechanical components of the machine.
  • slider 6 has been unlocked by the fact that the washing cycle termination safety members end their function, it is just necessary to press push-button device 1 all the way inwards, to its position shown in full lines in Figure 3. It carries on its body a sloping flat surface 11 adapted to react against a corresponding sloping surface 11a on slider 6, in order to move the latter towards the unlocking position of latch 4, which gets free from engagement with stop 2, thereby allowing port-hole door 5 to open completely as started and made easier by the spring recovery of seal ring 9 which had been kept compressed while the machine was closed. Meanwhile, push button 1 goes back to its starting position, shown in broken lines in Figure 3, under the biasing action of a quick-return spring 8 provided between the body and the seat of push button 1.
