Definitions

  • the present invention relates to an improved door-looking device.
  • the invention concerns a door locking device for household appliances, such as washing machines and like, particularly studied and realised to make safer starting procedures of said household appliances.
  • known door-locking devices suitable to lock a closed door provided with a suitably shaped hook comprise a frame having an opening, a movable slider, inserted within said frame, provided with a first slot for engaging the door hook when it is inserted within said opening of said frame, and a second slot or groove.
  • Said door-locking device also comprises return means, such as a spring, suitable to keep said slider in a set position, and a locking pawl, that can take an operative position, wherein it is withdrawn from a seat and is engaged with said second slot of said slider, and a rest position, wherein it is withdrawn within said seat.
  • Said locking pawl is controlled by an electro-mechanical device.
  • a door-locking device permitting keeping slider in such a position to prevent closure of the door, or to permit its closure, but so as to permit an easy opening also from inside, and so as to free slider only by activation of a control, only in this case permitting engagement of locking pawl.
  • a door-locking device comprising a frame provided with an opening wherein a hook, associated with a door of a washing machine or of an electric household appliance in general, can introduce and engage with said frame when said door is closed, a locking pawl, that can take a first position, wherein it is withdrawn preventing supply of said household appliance, and a second position, wherein its is extracted, permitting supply of said household appliance; and a moving slider arranged within said frame, said slider having a first slot suitable to interact with said hook, a second slot with which can be engaged said locking pawl in said second position, when said slider is in said locking position, to keep said hook engaged with said frame by said first slot when said door is closed, characterized in that said door-locking device further comprises safety means provided with control means, said safety means being provided with control means, said safety means being suitable to interact with said slider to control its position, so as to maintain said slider in said release position; and free said slider following operation of said control means, thus permitting them passing from said release
  • said slider can comprise a groove and said safety means comprise a safety pin capable of taking a rest position, in which it is disengaged from said groove and a operating position, in which it is engaged with said groove, blocking said slider, said safety pin taking said rest position following the activation of said control means.
  • said safety means can be configured so that when they interact with said slider, when said hook is disengaged from said frame, said slider is arranged in such way that said second slot is not faced to said blocking pawl, maintaining the latter in said first position and preventing said washing machine or electric household appliance in general to start.
  • said control means comprise an actuator electrically connected with and controlled by a control unit suitable to control the movement of said safety pin from said rest position to said operating position, and a push button configured so as to: activating said actuator and driving said safety pin in said rest position, when said push button is kept pushed and/or when it is only pushed; and/or activating said actuator and driving and keeping said safety pin in said rest position, when said push button is pushed according to a logic, controlled by said control unit.
  • Said door-locking device 10 comprises a frame 11 having an opening 12 with which can couple a hook 50 coupled with a door.
  • Said door-locking device 10 comprises a slider 20 and safety means 30, that can keep said slider 20 in a set position when a washing machine or other machine is switched off and the door is open.
  • Said door-locking machine 10 further comprises an electronic control unit 40, to control said safety means 30, and a control push button 34 or any other king of control.
  • Said safety means 30 comprise a safety pin 31, that can take a rest position, wherein it is withdrawn, and an operative position, wherein it is extracted, an actuator 32, electrically connected, controlled by said control unit and suitable to control movement of said safety pin 31 from said rest position to said operative position, and vice versa, and finally a spring 33 for returning said safety pin 31.
  • Said slider 20 has a first slot 21, with which said hook can interact, and a second slot 22, with which a locking pawl 60 can interact, said locking pawl 60 being connected to a micro switch preventing supply of machine when it is withdrawn.
  • Said slider 20 also has a groove 23, with which can engage said safety pin 31 when it is in an operative position.
  • Said first slot 21 of said slider 20 is provided faced on said opening 12 when said slider 20 is in a safety position, i.e. with safety pin 31 engaged with said groove 23.
  • door-locking device 10 Operation of door-locking device 10 occurs as follows, making particular reference both to figure 2 and to figures 3a-3b , showing operation of a known door-locking device, and to figures 4a-4b , showing operation of a door-locking device according to the present invention.
  • safety pin 31 When safety pin 31 is in an operative position, i.e. extracted, it is engaged with said groove 23, locking said slider 20 in such a position preventing to said locking pawl 60 engaging with relevant second slot 22, and to
  • hook 50 enters within opening 12, interacts with slider 20, which is moved by the same hook 50, thus permitting to the locking pawl 60 to engage with the second slot 22 of said slider 20.
  • actuator 32 is activated by control unit 40, withdrawing safety pin 31 in the rest position, releasing slider 20; then, door can be closed, inserting hook 50 within said opening 12.
  • slider 20 interacts with first slot 21, engaging with said frame 11 on the edge of said opening 12.
  • Said second slot 22 is faced to said locking pawl 60 that now, if activated, can interact with the same, locking slider 20, and hook 50, maintaining door closed. Now, even if free, safety pin 31 cannot engage with said groove 23, sliding on lateral surface of said slider 20.
  • locking pawl 60 When washing machine is activated, locking pawl 60, activated by said control unit 40, or by a further control unit, engages with said second slot 22, locking slider 20 so as to maintain door closed.
  • Safety pin 31 can be controlled electronically or mechanically by said push button 34, e.g. by a simple lever.
  • door-locking device 10 can be in three different states:
  • Door-locking device 10 thus permits reducing risk that a child can activate washing machine, enter within the basket and closing and locking the door making it impossible opening the same.
  • Activation can occur keeping pressed said push button, or by a single pulse that, by a suitable electronic circuit, keeps pin 31 disengaged from said groove 23 for a set time period, or by a stepped signal "t" or by any logic controlled by control unit 40 (it could be necessary pressing one or more times push button, or pressing the same for a set time interval, ecc.).
