Definitions

  • the present invention relates to a device designed to lock a door or drawer in a closed position closing an opening in the casing of an electric household appliance, such as a washing machine, drier, combination washing machine-drier, dishwashing machine, or oven, to which the following description refers purely by way of example.
  • an electric household appliance such as a washing machine, drier, combination washing machine-drier, dishwashing machine, or oven
  • Appliances of the above type also comprise a door locking device designed to lock the door in the closed position closing the opening when the machine is running, or to release the door to allow the user to open it when the machine is in a given rest/off state.
  • the electric actuating device normally comprises a box body fixed to the appliance casing, alongside the opening, and housing the pin; a solenoid, i.e. an electric coil connected to electric control means by a positive temperature coefficient (PTC) protection device; and a sliding rod, which is fitted inside the solenoid, is connected at its free end to the pin by links and/or by gears with motion-transmission cams, and is moved in and out of the solenoid, between a withdrawn position and an extracted position, by the magnetic field generated by the solenoid, to control the movement of the pin.
  • PTC positive temperature coefficient
  • the electric actuating device also comprises a safety device designed to automatically cut off electric power to certain electronic/electric devices, normally the electric motor rotating the laundry drum, when the locking device releases the door.
  • Some safety devices comprise a bimetallic spring; and a positive temperature coefficient (PCT) resistance pad positioned facing the bimetallic spring inside the box body, and which, when traversed by controlled current, lengthens/shortens the bimetallic spring to close or open an electric safety switch series-connected to the electric motor power line.
  • the bimetallic spring is normally designed to cooperate mechanically with the links or gears of the electric actuating device, to prevent the door from opening when the safety switch is closed.
  • a major drawback of door locking devices of the above type is the high electric consumption of the positive temperature coefficient parts, which, despite the reduction in their resistance when heated, still remain powered throughout operation of the appliance, thus resulting in a far from negligible increase in the total electric consumption of the locking device.
  • locking devices of the above type also have the drawback of being fairly slow to release, by depending on the time taken by the safety device PTC pad to cool.
  • EP 1 619 287 discloses an household appliance comprising a door block/release device which is actuated by electrically powered actuator means and comprises an actuation element made of shape memory material inserted within a movable body.
  • the device is capable of passing from the condition of blocking to that of releasing the door both by means of a movement of the actuation element caused by the electrical power supply control of the actuator means and by means of a manual actuation, using the housing body as an element of manual mechanical transmission.
  • the electric power means for powering the resistance wire thereby produce a controlled Joule-effect variation in temperature.
  • Number 1 in Figure 1 indicates as a whole an electric household appliance preferably, though not necessarily, corresponding to a washing machine, which comprises a casing 2; an inner compartment 3 corresponding to a laundry drum mounted inside casing 2 and facing an opening 4 in casing 2; and a door 5 hinged to casing 2 to rotate, about a preferably, though not necessarily, vertical axis, between an open position and a closed position opening and closing opening 4 respectively.
  • inner compartment 3 corresponds to a baking compartment formed in the oven casing
  • the door corresponds to a door hinged to the casing to close the access opening to the baking compartment.
  • Appliance 1 also comprises a locking device 6 for locking door 5 in the closed position closing opening 4, when appliance 1 is in a predetermined operating state, or for releasing door 5 to allow it to move, or be moved, into the open position ( Figure 1 ) when appliance 1 is in a predetermined rest state.
  • locking device 6 comprises a preferably, though not necessarily, parallelepiped-shaped box body 7 having a longitudinal axis A and fixed to casing 2, alongside opening 4; and a latch 8 hinged to a first end 7a of box body 7 to rotate, about an axis of rotation B perpendicular to axis A, between a lock position ( Figure 5 ), in which latch 8 engages a catch 5a, projecting from the end of a catch arm 5b on door 5, to lock door in the closed position; a release position ( Figure 4 ), in which latch 8 is released from catch 5a on door 5, to permit withdrawal of catch 5a from latch 8 and disconnect door 5 from casing 2; and a rest position ( Figure 3 ), in which latch 8 is fully released from catch 5a on the catch arm on door 5.
  • Locking device 6 also comprises an actuator 11 housed inside box body 7 and designed to move latch 8 selectively into the lock position, in which latch 8 is locked to catch 5a on door 5; into the release position, in which latch 8 is released from catch 5a to open door 5; or into the rest position, in which catch 5a is fully detached from latch 8.
  • actuator 11 comprises a movable end member or carriage 12, which is mounted to slide on the major inner face of box body 7 along an axis C parallel to axis A, and is connected mechanically to latch 8 so that the axial movement of carriage 12 rotates latch 8 selectively about axis B into the rest position, lock position, or release position.
  • carriage 12 is movable between a first position ( Figure 3 ) at a minimum distance from end 7a to hold latch 8 in the rest position; a second position ( Figure 4 ) at a maximum distance from end 7a to hold latch 8 in the release position; and a third position ( Figure 5 ) at an intermediate distance, between the minimum and maximum distances, from end 7a, to hold latch 8 in the lock position.
  • carriage 12 moves in a reverse direction D into the second position, or in a forward direction E, opposite reverse direction D, into the first position.
  • actuator 11 also comprises elastic thrust means 14 designed to exert a predetermined elastic force on carriage 12 in direction E, so as to elastically oppose the movement of carriage in reverse direction D and push it into the first position.

  • intermediate portion 13c of traction pin 13 is designed to allow latch 8 to move freely with respect to traction pin 13 and rotate between the lock position and rest position when carriage 12 is in the first position, and to hold latch 8 against partition 17 when carriage 12 is in the second position.
  • Front portion 13b of traction pin 13 is designed to engage slot 5c in catch 5a on door 5 when latch 8 is in the lock position, so as to hold the lock surface of latch 8 resting on the lock surface of catch 5a and connect catch 5a to latch 8, and is designed to secure and rotate latch 8 about axis B towards partition 17 when carriage 12 moves in reverse direction D.
  • elastic thrust means 14 comprise a leaf spring, i.e. a U-shaped strap of elastic, electrically conducting material, which has two ends 14a fixed rigidly to respective portions of the lateral walls 7c of box body 7 extending parallel to and on opposite sides of axis A; and a central segment 14b, preferably corresponding to the bend in the spring, fitted firmly to carriage 12 to exert elastic thrust on traction pin 13 in the forward direction E.
  • leaf spring i.e. a U-shaped strap of elastic, electrically conducting material
  • central segment 14b of leaf spring 14 is connected firmly to carriage 12 at rear portion 13a of traction pin 13, so as to keep traction pin 13 substantially aligned with axis C as carriage 12 moves; and the two wings 14c and 14d of spring 14 are designed to remain substantially straight and parallel to axis C when carriage 12 is in the first position, and to flex gradually outwards, in opposite directions F perpendicular to axis A, i.e. towards lateral walls 7c of box body 7, into a fully flexed position ( Figure 6 ) when carriage 12 is moved into the second position, and into a partly flexed position ( Figure 5 ) when carriage 12 is moved into the third position.
  • the end of one of the wings, 14d, of spring 14 is connected to a first electric connector 18a of power means 18 by a strap of electrically conducting material; and central segment 14b of spring 14 is connected electrically to a second electric connector 18b of power means 18 by wire 16, and by an automatic switch 23, which opens automatically when electric current flow along wire 16 exceeds a predetermined maximum threshold, to prevent Joule-effect overheating and damage/failure of wire 16.
  • automatic switch 23 comprises a fixed electric contact 24 connected electrically to second electric connector 18b; and an oscillating arm 25 made of electrically conducting material, and which has a free end fitted with a movable electric contact 26 facing fixed electric contact 24, and an opposite end pivoting inside box body 7 to allow arm 25 to oscillate partly, about an axis G perpendicular to axes A and B, between a closed position ( Figure 3 ) in which movable electric contact 26 rests on fixed electric contact 24, and an open position (not shown) in which movable electric contact 26 is detached from fixed electric contact 24.
  • Automatic switch 23 also comprises an elastic member 27, e.g. a spring, interposed between arm 25 and an inner wall of box body 7 to hold arm 25 in the closed position; and a head 28 designed to connect the second end of wire 16 to arm 25, and which, alongside a variation in the length of wire 16, moves between a first and second position along axis C to swing arm 25 between the closed and open positions.
  • an elastic member 27 e.g. a spring
  • Elastic member 27 is designed so that head 28, activated by wire 16, moves arm 25 into the open position when current flow along wire 16 exceeds the predetermined maximum threshold.
  • first end of wire 16 is connected electrically to central segment 14b of spring 14, and the second end is connected to a preferably, though not necessarily, central portion of arm 25.
  • wire 16 is made of nickel-titanium alloy, and is wound about head 28 and cylindrical portion 12a of carriage 12 to form a coil. More specifically, wire 16 is long enough to wind about carriage 12 and head 28 in a number of turns, which are kept taut between head 28 and carriage 12, and define five wire branches extending between carriage 12 and head 28 and substantially parallel to axis A.
  • wire 16 has a total length, measured between the first and second end at ambient temperature, of roughly 387 mm, is roughly 0.2 mm in diameter, and is designed to vary in crystalline structure, and therefore length, when subjected to a predetermined transformation temperature, e.g. of roughly 100°C.
  • carriage 12 and head 28 may either be connected or comprise two comb members 50, 51 mounted inside box body 7 to slide, parallel to axis C, between the positions described above; elastic thrust means 14 comprise one or more springs 52 interposed between comb members 51 and 52; and wire 16 advantageously comprises a crimped wire inserted inside the gaps between the teeth of comb members 50 and 51, with the crimped ends 53 resting on opposite outer faces of comb members 50 and 51.
  • crimped ends 53 are equally spaced along wire 16, and, when the wire is inserted inside the gaps in comb members 50 and 51, keep comb members 50, 51 parallel to each other and a given distance apart.
  • a crimped wire 16 in comb members 50, 51 of carriage 12 and head 28 has the big advantage of enabling fast, low-cost assembly of the wire to head 28 and carriage 12, and ensuring correct spacing of head 28 and carriage 12 by means of the crimped ends, which act as locators when assembling the device.

As it cools, wire 16 increases in length and, at the same time, elastic thrust means 14 restore carriage 12 to the first position, thus extracting traction pin 13 and allowing the elastic members to restore latch 8 to the rest position ( Figure 3 ).
  • latch 8 In the release position ( Figure 4 ), latch 8 is secured by traction pin 13 to carriage 12, and rests against partition 17 to prevent any further withdrawal of carriage 12 in direction D. Any increase, over and above the predetermined threshold, in current flow through wire 16 therefore produces a further reduction in the length of wire 16, which moves head 28 in direction E, in opposition to the force exerted by elastic member 27 on oscillating arm 25, so oscillating arm 25 rotates into the open position opening automatic switch 23.
  • locking device 6 may also be used to advantage in technical applications other than electric household appliances as described above.
  • it may be used to lock a drawer or door in a closed position closing a compartment formed in furniture, or in vehicles, such as motor vehicles, aircraft, trains, ships, or similar.
  • the locking device described has the advantage of being electrically and mechanically simpler, and therefore faster and cheaper to produce.
  • the safety switch of the locking device is designed to only supply power, e.g. to the electric motor, when the door is fully closed, thus making the appliance safer.
  • the locking device is also efficient in terms of energy saving, by featuring no electronic, positive-temperature-coefficient components.
