Definitions

  • the present invention relates to a laundry washing and/or drying appliance comprising a front door having an ergonomic front door opening mechanism.
  • the laundry treatment appliances such as for instance washing machines, drying machines and combo washing/drying machines comprise a rotary drum in which cloth items are placeable and accessible via a front door, a water tub in which the rotary drum is rotatable and a motor providing said rotary drum to be driven by means of a pulley mechanism, the latter being disposed outside said tub.
  • laundry treatment appliances have front doors typically allowing access into the rotary drum for loading and unloading the laundry to be processed.
  • a front door opening mechanism typically functions in the manner that a handle associated with a handle lever is rotatable to drive a hook lever, the latter being actuable to lock or unlock the front door.
  • the handle lever and the hook lever therefore cooperate to initiate the proper positioning of the mechanical components such that an engagement end of the hook lever is displaced a certain distance to be released from a locking slot.
  • a problem associated with the above-described mechanical design lies in that while a given user reaches for a handle cover to unlock the front door of the laundry treatment appliance by way of retracting the handle lever relative to the handle cover, he/she may experience that he/she can insert his/her fingers through an opening in between the handle cover and the handle lever. This situation, normally not posing a serious risk of trapping fingers in the mechanism, may be a cause for complaint for some due to the existing opening. Obviously, one can design a larger skirt portion for the handle cover to cover a larger portion of the in-between opening but in this case it will be more difficult to operate the lock mechanism so as to handle the same with an ergonomic use on the part of the users.
  • the present invention therefore proposes an arrangement according to which the opening in between the handle cover and the handle lever is not noticeable to the users.
  • EP0349494 A prior art publication in the technical field of the present invention may be referred to as EP0349494 among others, the document disclosing a door lock for front-loading washing machines, comprising a support body associated with the structure of the machine and a lever articulated to the body and having an end opposite the articulated end which is connected to a flexible operating cable.
  • a slide is articulated to the lever and has a lateral edge surface situated adjacent an aperture in the body, which is provided for the passage of a catch member connected to the door of the machine.
  • the lateral edge surface of the slide also has a cut-out portion for enabling the catch member to be released, and consequently the door to be opened, when the slide slides.
  • the present invention provides an arrangement in relation to laundry treatment appliances having a front door opening mechanism, the mechanism involving a handle cover and a handle lever the dimension of the opening in between which is reduced as defined by the characterizing features in Claim 1.
  • Primary object of the present invention is hence to provide a laundry treatment appliance having an ergonomic front door opening mechanism.
  • the present invention proposes a laundry treatment appliance having a lock mechanism for locking and unlocking the front door thereof.
  • a handle operates a hook lever in mechanical engagement whereby a locking member is rotated.
  • Both said handle and said hook lever have separate axes of rotation in the manner that the amount of rotation of the handle is less than that of the hook lever, meaning that displacement of the handle relative to the fixed handle cover can be limited.
  • the handle transfers rotational movement to the hook lever by a contact surface such that they remain in mechanical contact during locking and unlocking of the front door.
  • This contact surface displaces between two end positions when the lock mechanism is operated and the trajectory of the contact surface forms a plurality of lines. If any of these lines is accepted as the trajectory line, the shortest distance from the axis of rotation of the hook lever to the line is shorter than the shortest distance from the axis of rotation of the handle to the same line.
  • the angle formed between two lines extending from the axis of rotation of the hook lever to the two ends of the line is larger than the angle formed between two lines extending from the handle pivot pin axis to the same two ends of said line.
  • Fig. 1 demonstrates a general perspective view of a laundry treatment appliance with a front door.
  • Fig. 2 demonstrates a general perspective view of a laundry treatment appliance front door.
  • Fig. 3 demonstrates a general perspective view of a laundry treatment appliance front door according to the present invention in an unassembled manner.
  • Fig. 4 demonstrates a general perspective view of a laundry treatment appliance front door according to the present invention
  • Fig. 5 demonstrates a front view of a laundry treatment appliance front door according to the present invention
  • Fig. 6 demonstrates a cross-sectional side view of the lock mechanism along lines B-B as indicated in Fig. 5 according to the present invention.
  • Fig. 7 demonstrates a cross-sectional side view of the lock mechanism in two different positions along lines B-B as indicated in Fig. 5 according to the present invention.
  • Fig. 8 demonstrates another cross-sectional side view of the lock mechanism in two different positions along lines B-B as indicated in Fig. 5 according to the present invention.
  • the present invention relates to a laundry treatment appliance (1) comprising a water tub, a rotary drum, in which the laundry is to be placed and an electric motor rotating the drum.
  • a front door (3) typically allows access into the drum for loading or unloading laundry through an access opening (2).
  • the front door (3) of the laundry treatment appliance (1) is conventionally openable around a door hinge (5) and a lock mechanism (6) releasably secures an engagement end (13) part to a locking slot.
  • a handle (7) is provided such that rotation thereof around a handle pivot pin (9) drives a hook lever (10), the latter being rotatable around a hook pivot pin (11) and actuable to lock or unlock the front door (3).
  • the handle (7) and the hook lever (10) therefore cooperate to effect locking and unlocking of the front door (3).
  • the present invention provides that the handle pivot pin (9) around which the handle (7) is rotated and the hook pivot pin (11) around which the hook lever (10) is rotated are not coaxial such that the amount of rotation of the handle (7) can be adjusted to be less than that of the hook lever (10), in which case the locking mechanism (6) operates with a shorter displacement of the handle (7) and locking and unlocking is effected during which no in-between opening is generated and accidental trapping of fingers is prevented.
  • the handle (7) maintains a contact surface (12) with the hook lever (10) such that the two parts remain in mechanical engagement with each other during locking and unlocking of the front door (3). Rotational movement imparted to the handle (7) by the user is therefore transferred to the hook lever (10).
  • the shortest distance (L 4 ) from the position of the axis of rotation of the hook lever (10) to a line two ends of which are defined by the trajectory of the contact surface (12) during locking and unlocking of the front door (3) is shorter than the shortest distance (L 3 ) from the position of the axis of rotation of the handle (7) to the same line.
  • the shortest distance from the axis of the hook pivot pin (11) to the line formed between two end positions of the contact surface (12) during locking and unlocking is shorter than the shortest distance from the axis of the handle pivot pin (9) to the same line.
  • the angle c 3 formed between two lines extending from the hook pivot pin (11) axis to the two ends of the line defined by the trajectory of the contact surface (12) is larger than the angle c 4 formed between two lines extending from the handle pivot pin (9) axis to the same two ends of the trajectory line.
  • the angle c 3 is larger than the angle c 4 , the same trajectory line being formed across from the two angles, i.e. c 3 and c 4 .
  • the present invention proposes a laundry treatment appliance (1) comprising a rotary drum in which the laundry is placeable and, an electric motor rotating the rotary drum and a front door (3) allowing access into the rotary drum for loading or unloading laundry through an access opening (2), the front door (3) being openable around a door hinge (5) in the manner that a lock mechanism (6) releasably secures an engagement end (13) such that the front door (3) is lockable and unlockable.
  • a handle (7) is provided to be rotatable around a first axis of rotation in mechanical communication with a hook lever (10) that is drivable by the handle (7), the hook lever (10) being rotatable around a separate second axis of rotation whereby the engagement end (13) is actuable to lock or unlock the front door (3).
  • the handle (7) is rotatable around a handle pivot pin (9) and the hook lever (10) is rotatable around a hook pivot pin (11).
  • the amount of rotation of the handle (7) is configured to be less than that of the hook lever (10).
  • the handle (7) and the hook lever (10) maintain a contact surface (12) with each other such that they remain in mechanical engagement during locking and unlocking of the front door (3).
  • the shortest distance (L 4 ) from the position of the axis of rotation of the hook lever (10) to a line two ends of which are defined by a trajectory of the contact surface (12) during locking and unlocking of the front door (3) is shorter than the shortest distance (L 3 ) from the position of the axis of rotation of the handle (7) to the same line.
  • the shortest distance (L 4 ) from the axis of rotation of the hook pivot pin (11) to a line formed between two end positions of the contact surface (12) during locking and unlocking is shorter than the shortest distance (L 3 ) from the axis of rotation of the handle pivot pin (9) to the same line.
  • the angle c 3 formed between two lines extending from the hook pivot pin’s (11) axis of rotation to the two ends of the line defined by the trajectory of the contact surface (12) is larger than the angle c 4 formed between two lines extending from the handle pivot pin (9) axis to the same two ends of said line.
