Definitions

  • the present invention refers to a laundry washing and/or drying machine comprising a front loading door, a hinge to pivot said door to the machine cabinet, a door lock/release system and a device for the manual actuation of the lock/release system (see DE-A-2 405 143).
  • a door usually having a circular shape, through which the user can reach inside the machine drum to perform the usual loading and unloading operations of the laundry.
  • a door or porthole is generally hinged to the cabinet by means of a hinge comprising a fixed part fastened to the machine body and a movable part integral with the porthole, the rotation axis of the hinge, and consequently of the door, being vertical.
  • the machines of said type are further provided with a door lock/release system, to keep the door closed during the machine operation and allow its opening for the loading and unloading of the clothes.
  • the door lock/release system is provided with a suitable actuation handle located on the door itself, on the opposite side with respect to the hinge; moreover, said handle with the relevant kinematic motion of the lock/release system and the hinge are always aligned, one on the door right-hand side and the other on the left hand-side, in line with the center-line of the door or of the loading aperture.
  • the door rotary motion has to be performed by the user completely by hand due to the inherent hinge characteristics, unless some complex spring mechanisms are provided that allow a kind of automatic complete opening of the door after it was unlocked by the proper handle.
  • the position of the door opening handle in line with its center-line may at times be difficult to reach, above all in such instances when the user is holding a container full of clothes to be washed.
  • a laundry washing and/or drying machine comprising a front loading door, a hinge to pivot said door to the machine cabinet, a lock/release system of the door and a device for the manual actuation of the lock/release system, characterized in that said hinge is fastened to the cabinet so that the rotation axis of the door is inclined in respect to the vertical axis of the machine, whereby said inclination of the rotation axis of the door is suitable to allow an autonomous opening motion of the door, after that the latter has been released through said manual actuation device.
  • number 1 indicates as a whole the laundry washing and/or drying machine according to the present invention; said machine comprises a steel-sheet cabinet 2, whose upper section houses a control panel 3; the cabinet front side has an opening indicated by number 4 to reach inside the machine drum for the normal laundry loading/unloading operations.
  • Number 5 indicates as a whole the front loading door of the machine 1, which is provided for the closure of said aperture 4, specifically during the machine operation.
  • the machine 1 is provided with a manual lock/release actuation system which comprises a hook 6 on the door 5 and an actuation handle 7, which is suitable either to lock or release said hook; moreover, inside the door 5 some further mechanical means are provided, which are part of the lock/release system, such as for example a spring, not shown in the figures for simplicityis sake.
  • a manual lock/release actuation system which comprises a hook 6 on the door 5 and an actuation handle 7, which is suitable either to lock or release said hook; moreover, inside the door 5 some further mechanical means are provided, which are part of the lock/release system, such as for example a spring, not shown in the figures for simplicityis sake.
  • the door lock/release system also comprises a seat indicated by 8 on the machine cabinet 1 where, during the closure of the door the hook 6 can enter and engage through elastic means; the seat 8 is coupled inside the cabinet 1 with a suitable electric safety device, that locks the hook 6 mechanically during the whole machine operation cycle, so as to prevent an accidental opening of the door 5.
  • FIG 3 the fixed part of a hinge integral with the machine cabinet is indicated with 9, said hinge being the one usually provided to pivot the door 5 to the machine cabinet.
  • the horizontal center-line of the hinge element 9 results in being inclined with respect to the center-line of the aperture 3 or of the door 4.
  • the hinge rotation axis on which the door 5 rotates is inclined in respect to the machine vertical axis (M); just by way of example, in figure 2 the door rotation axis indicated by S has an inclination being delayed to the clockwise motion of 5 degrees with respect to the machine vertical axis, indicated by M.
  • said inclination of the hinge rotation axis S is selected so that, once the door 5 is released by the handle 7 and slightly open, it will then perform a complete opening motion on its own through the combined action of its weight and misalignment against the vertical axis.
  • This arrangement is also particularly advantageous due to the fact that, when the door has reached its opening position, it will tend to keep it or resume it on its own, should the user casually move the door; this is a different situation from the known machines, where often the door can only remain half-open, thus causing a hindrance for the user.
  • the machine 1 has a door opening handle and a related lock/release system whose elements are located in the upper half of teh same door, in an ergonomically comfortable position.
  • the handle 7 may be located at about 40 degrees in respect to the door center-line, whereas the hook 6 and the seat 8 may be about 30 degrees from it; both the handle and the lock/release system may also be located with the same inclination or different inclinations against the ones indicated by way of example.
  • the door opening motion can in fact be obtained completely on its own, without requiring any manual displacement of the door by the user; as a matter of fact, the lock/release systems of the kind already known are usually capable of producing only a certain initial opening thrust when the door is unlocked; this is typically due to the availability of some elastic means opposing the door locking and to the flexible reaction of the bellows-type seal, usually being present in correspondence of the door aperture, to seal the door.
  • the present invention has a specific advantageous application in the case of machines where the door lock/release system is controlled by a push-button on the control board; in this case, in fact, said initial thrust on the door and the inclination of the door rotation axis according to the present invention allow to perform a complete and practically automatic door opening motion.
