Definitions

  • the present invention relates to an electric household appliance door opening device.
  • the present invention relates to a refrigerator door opening device, to which the following description refers purely by way of example.
  • a refrigerator normally comprises a refrigeration compartment defined by a main body, and by a door hinged to the main body and having an annular seal which rests against a metal edge of the main body.
  • the seal houses magnet portions which adhere to the metal edge of the main body to lock the door in the closed position.
  • refrigerator doors are fitted with opening devices.
  • One such device is described in Patent US 2,659,115, and comprises a handle hinged to the refrigerator door; and a pusher, which is movable with respect to the refrigerator door, is hinged to the handle, and rests against the edge of the main body to detach the door from the edge.
  • the handle and pusher form a lever mechanism by which to detach the door with very little effort.
  • the above patent in fact, describes a basic principle, variations of which have been applied in various types of refrigerator door opening devices.
  • an opening device for opening a door of an electric household appliance, wherein the electric household appliance comprises a main body and a door hinged to said main body; the opening device being supported by said door, and comprising a handle hinged about a first axis, and a pusher connected to said handle and for detaching the door from said main body; the opening device being characterized by comprising emitting means for emitting a signal; emission of said signal being determined by operation of said opening device.
  • Number 1 in Figure 1 indicates as a whole a refrigerator comprising a main body 2; a door 3 hinged to main body 2; and an opening device 4 for opening door 3.
  • Main body 2 defines an inner cavity with door 3, and comprises a metal edge 5 ( Figures 2 and 3) along which door 3 rests in the closed position ( Figure 2).
  • Door 3 supports device 4, and is hinged to main body 2 about an axis (not shown) parallel to a direction D1 and located on the opposite side to device 4.
  • door 3 comprises an outer face 6; and an inner face 7, along which extends an annular seal G cooperating with edge 5.
  • Seal G contains magnets M which generate a force of attraction between door 3 and edge 5 to keep door 3 in the closed position.
  • Device 4 comprises a shell-shaped supporting frame 8 located partly between faces 6 and 7 of door 3; a handle 9 extending in front of outer face 6; a pusher 10 projecting from inner face 7 towards edge 5; and a transmission mechanism 11 between handle 9 and pusher 10.
  • Frame 8 comprises a channel 12, through which pusher 10 extends; comprises an arm 13 projecting from face 6 and supporting handle 9 about a horizontal axis 14; and supports transmission mechanism 11 and pusher 10.
  • Handle 9 defines a lever comprising an arm 15, which is substantially parallel to face 6, extends vertically beneath axis 14, and defines the grip of handle 9; and an arm 16, which is substantially perpendicular to face 6, is much shorter than arm 15, and has a surface 17 mating with mechanism 11.
  • Pusher 10 extends perpendicularly to face 7, is supported at a first end by transmission mechanism 11 and at a second end by a guide 18 fitted along face 7 of door 3, and comprises a head 19 connected to the second end of pusher 10 and cooperating with guide 18.
  • mechanism 11 comprises a lever 20 defined by an arm 21 perpendicular to face 6, an arm 22 parallel to face 6, and a pin 23 parallel to axis 14 and which connects arms 21 and 22 and defines an axis 24 of rotation of lever 20.
  • Arm 21 has a surface 25 which mates with surface 17 of arm 16 ( Figure 2), and arm 22 is connected to pusher 10 by a pin 26 defining an axis 27 parallel to axis 14.
  • Mechanism 11 also comprises a spring 28 ( Figures 2 and 3); and a member 29 cooperating with pin 26.
  • spring 28 is housed in a seat 30 of arm 22 and in a seat 31 of frame 8 to keep pusher 10 in the rest position shown in Figure 2.
  • member 29 comprises a C-shaped support 32 fixed to frame 8 and having a seat 33 housing a ball 34 retained inside seat 33 by a spring 35.
  • Seat 33 has a hole smaller in diameter than ball 34, so that ball 34 projects partly through seat 33.
  • Pin 26 is located beneath seat 33 and interferes with ball 34 when pusher 10 is moved.
  • pin 26 no longer interferes with ball 34, which is clicked back into seat 33 by spring 35 and emits the acoustic signal.
  • spring 28 restores handle 9, pusher 10, and mechanism 11 to the original position. And, as it moves back, pin 26 again interferes with ball 34 to emit the acoustic signal.
  • the acoustic signal Since the back and forth travel of pusher 10 and pin 26 normally takes place in rapid succession, the acoustic signal has the characteristic click-clack sound typical of a lock.
  • the signal is emitted to indicate operation of opening device 4 and, therefore, that door 3 is open, so that any accidental opening of the door is also indicated.
  • Member 29 is actually a mechanism for emitting an acoustic signal and at the same time resisting operation of handle 9.
  • resistance varies as a function of the movement of handle 9 in much the same way as bolt locking mechanisms.
