Description

  • The present invention relates to a laundry treatment appliance, such as a laundry washing and/or drying machine, having a front door comprising a handle assembly whereby the durability of the door handle assembly is improved and its installation is simplified.
  • It is well-known that laundry treatment appliances such as 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. To this end, 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 locking mechanism typically functions in the manner that a handle associated with a handle lever is rotatable to drive a hook lever, the latter being actuatable to lock or unlock the front door. When the door is closed, the hook settles into a locking slot of a locking arm while a safety latch provides an interengaged connection with the hook to ensure fixedly closing of the door.
  • The above-described mechanical design allows a given user to reach for a handle cover to unlock the front door of the laundry treatment machine by way of retracting the handle lever relative to the handle cover. It is to be noted that the mechanical structure outlined above can be designed by various connection elements, which may substantially affect production efficiency of the laundry treatment machine as a large number of individual elements can be necessary for the operation of the locking mechanism.
  • Therefore, a more efficient manner of providing operational functionality with a simplified mechanical structure is desirable so as to decrease manufacturing costs through reduction of involved components and accordingly man-hours. In addition, due to the shape and design of the door of the laundry treatment device, only a narrow space is available for the placement of the components for the attachment of the handle assembly. Therefore, it is advantageous to use specially designed attachment components to fit in the available space. In this way, the handle attachment components are easily hidden beneath the handle of the front door and also do not cause irritation to the user's hand by forming a rough surface on the back of the handle.
  • The present invention proposes a laundry treatment machine with an alternative simplified mechanical arrangement to obtain a front door handle assembly in a laundry treatment machine.
  • Among others, a prior art publication in the technical field of the invention may be referred to as WO2013189859 , which discloses a door assembly for a laundry treatment appliance that comprises a first and a second component attachable to each other by at least one snap-fit connector. The first component is on the drum facing surface of the front door, and the second component is on the forwards facing surface around the drum opening. The snap fit connector comprises at least one first engaging element, for example a hook, and at least one corresponding second engaging element, for example a ledge. The at least one first and second engaging elements are distributed along the surface of the first and second components respectively. When the user closes the front door of the laundry appliance, the first engaging elements and the corresponding second engaging elements are mated and therefore the front door is locked. Document WO 2016/119833 A1 discloses another handle assembly for a laundry treatment appliance.
  • Further, Document WO 2017/020959 A1 is relevant for Article 54(3) EPC and discloses a laundry treatment appliance comprising a rotary drum in which laundry is placeable and a front door allowing access into the rotary drum for loading or unloading laundry through an access opening and having a handle assembly operateable to lock or unlock said front door, the handle assembly comprises a handle body, a handle edge piece and a handle inner piece, the handle edge piece comprises a central edge tab and at least one peripheral edge tab and the handle body comprises corresponding central edge slot and at least one peripheral edge slot such that the handle edge piece is attachable to the handle body by insertion of the central edge tab and of at least one peripheral edge tab into corresponding central edge slot and at least one peripheral edge slot, the handle body comprises at least one inner hook and said handle inner piece comprises corresponding at least one inner slot such that the handle inner piece is attachable to the handle body by insertion of said at least one inner hook into corresponding at least one inner slot, the handle inner piece comprises flexible inner tab whereby the inner hook is kept in the inner slot by the flexible inner tab.
  • The present invention, on the other hand, addresses the situation where the structure of a handle assembly for a front door of a laundry treatment appliance such as a laundry washing and/or drying machine is simplified to provide durability and ease of installation.
  • To this end, the present invention provides an effective system in which the handle assembly is assembled by attachment of a handle body with a handle edge piece and handle inner piece via tabs and corresponding slots.
  • The present invention provides a front door for a laundry treatment appliance comprising a handle assembly as provided by the characterizing features defined in Claim 1.
  • Primary object of the present invention is to provide a front door comprising a handle assembly for a laundry treatment appliance such as a laundry washing and/or drying machine whereby the durability of the door handle assembly is improved and its installation is simplified.
  • The present invention proposes a laundry treatment appliance with front door handle assembly having a handle body, handle edge piece and handle inner piece. Flexible inner tabs of the handle inner piece keep inner hooks of the handle body in inner slots of the handle inner piece. Flexible peripheral edge tabs of the handle body keep peripheral edge hooks of the handle edge piece in peripheral edge slots of the handle body.
