Definitions

  • the solution according to one or more embodiments of the present invention relates to the field of appliances. More specifically, this solution relates to hinges for appliances.
  • Appliances are routinely used to accomplish a number of household functions; for this purpose, the appliances may be either freestanding or integrated with other pieces of furniture.
  • a decorative front panel - normally with the same appearance of the other pieces of furniture - is mounted on the appliance.
  • the dishwasher With reference in particular to a dishwasher integrated in a kitchen, the dishwasher is called of the built-in type when it has its control panel exposed or of the full-integrated type when it is completely covered by the corresponding decorative front panel; the dishwasher of the full-integrated type is totally indistinguishable from the other pieces of furniture of the kitchen (even if it requires to be opened to access the control panel).
  • the dishwasher has a front load opening, which is closed by a corresponding door.
  • the door is pivoted on top of a base of the dishwasher (by means of a pair of lateral hinges); in this way, the door may rotate (during its opening and closing) around a horizontal rotation axis raised from the floor.
  • the decorative front panel has the same length as the door (with the base of the dishwasher that is covered by a baseboard, or plinth, of the kitchen); in other countries, instead, the decorative front panel is longer than the door (so as to project below it).
  • the lower end of the decorative front panel may interfere with the baseboard when the door is completely open (depending on a height of its pivoting area). This problem is generally addressed by providing a clearing in the baseboard under the decorative front panel.
  • some known dishwashers are provided with a recess in their base for receiving the projecting portion of the decorative front panel.
  • this recess involves a remarkable waste of room in the dishwasher; moreover, it requires the manufacturing of different versions of the same dishwasher (according to the lengths of the decorative front panels to be mounted).
  • EP-A-1529482 describes a dishwasher with a spring mounted on the door for pushing the decorative front panel downwards.
  • the decorative front panel reaches the base of the dishwasher, so as to be pushed upwards in opposition to the spring; vice-versa, when the door is closed the spring returns the decorative front panel to its rest position.
  • this structure only allows the use of decorative front panels that are slightly longer than the door.
  • the articulated lever mechanism includes an arcuate tie-rod that is coupled with a hinge of the door (formed by a bracket integral with a body of the dishwasher, and a rotating sector integral with the door) - more specifically, with the tie-rod that pivots around the rotating sector.
  • a rod and an arm are then hinged to a free end of the tie-rod.
  • the other end of the rod is hinged to the body, whereas the other end of the arm is hinged to the decorative front panel. Therefore, the opening of the door rotates the tie-rod; the tie-rod then rotates the arm, which in turn rotates the rod until it abuts against the decorative front panel, thereby moving the decorative front panel upwards.
  • a drawback of the structure described in EP-A-1894509 is that it requires the addition of a specific articulated lever mechanism to the dishwasher.
  • This articulated lever mechanism is quite cumbersome and it protrudes below the hinges of the dishwasher; therefore, as above this requires the manufacturing of different versions of the same dishwasher (with or without the articulated lever mechanism according to the lengths of the decorative front panels to be mounted).
  • the sliding of the decorative front panel may be not immediate when the door is opened (since the articulated lever mechanism may have a certain dead time required by the rod to abut against the decorative front panel); therefore, the decorative front panel has to be maintained in any case raised from the floor to allow the initial opening of the door before the decorative front panel raises.
  • an arcuate tie-rod is hinged to the rotating sector of the hinge (integral with the door).
  • the telescopic mechanism includes an L-shaped arm that is hinged at its corner to the bracket integral with the body of the dishwasher.
  • a short side of the L-shaped arm is hinged to a free end of the tie-rod; a long end of the L-shaped arm instead consists of a telescopic rod, which is hinged to the decorative front panel. Therefore, the opening of the door rotates the tie-rod; the tie-rod then rotates the L-shaped arm, which in turn moves the decorative front panel upwards (while the length of the telescopic rod adapts accordingly).
  • EP-A-1875850 substantially suffers the same drawbacks pointed out above. Particularly, it requires the addition of a specific telescopic mechanism to the dishwasher; moreover, this telescopic mechanism is quite cumbersome and it protrudes below the hinges of the dishwasher (thereby requiring the manufacturing of different versions of the same dishwasher with or without the telescopic mechanism).
  • a solution according to one or more embodiments of the present invention is based on the idea of implementing the sliding of the decorative front panel within the hinges.
  • a first aspect of a solution according to the invention provides a hinge for use in a domestic appliance (for example, in a full-integrated dishwasher) to rotationally connect a door of the appliance to a body of the appliance;
  • a decorative front panel can be mounted in front of the door, and arranged slidably in an essentially orthogonal direction relative to a rotation axis of the door with respect to the body (for example, this sliding direction extends within a plane being orthogonal to the rotation axis of the door and including it, or the sliding direction extends within a plane that is essentially parallel to a plane being orthogonal to the rotation axis of the door and including it;
  • the rotation axis of the door either may have a fixed position with respect to the body throughout the rotation of the door, such as coincident with a fulcrum of the hinge when it is of the single fulcrum type, or it may move on a curved line during the rotation of the door, such as when the hinge is of the double fulcrum
  • the hinge includes a support bracket for connection to the body, and a rotating bracket for connection to the door; the rotating bracket is rotationally connected to the support bracket.
  • the hinge further includes a driving mechanism arranged to interact both with the support bracket and the rotating bracket to be operated when the rotating bracket is rotating.
  • the rotating bracket includes an elongated guide structure, which extends essentially orthogonally to the rotation axis of the door.
  • the rotating bracket further includes a sliding block for connection to the decorative front panel, which sliding block is slidably guided along the elongated guide structure.
  • the sliding block cooperates with the driving mechanism to achieve a sliding of the sliding block along the elongated guide structure, and a corresponding sliding of the decorative front panel with respect to the door, during the rotation of the rotating bracket
  • the driving mechanism may be a lever mechanism also used to operate a balancing device of the appliance, which lever mechanism cooperates with the sliding block by means of a crank mechanism, or the driving mechanism may be a dedicated first gear mechanism, which cooperates with the sliding block by means of a second gear mechanism.
  • the present invention has the particular advantage that the mechanism that drives the translation of the decorative front panel with respect to the appliance door is integrated into the hinges of the invention themselves. Thus, there need not be any additional levers that are arranged below the hinge.
  • the invention allows in particular to use decorative front panels that are shorter as compared to the prior art in the sense that they do not need to reach below the appliance door in the closed state thereof in order to cover any visible levers below the hinge and that would disturb the esthetical impression generated by the appliance if visible during the closed state of the door.
  • Such relatively short decorative panels are desirable in arrangements wherein the appliance is integrated into a kitchen furniture, in particular at a height position above a ground row of furniture.
  • a second aspect of a solution according to the invention provides a domestic appliance (for example, a dishwasher of the full-integrated type), which includes a body, a door, and a pair of the hinges of the first aspect of the invention that rotationally connect the door to the body at opposite sides thereof; each hinge has the corresponding support bracket connected to the body and the corresponding rotating bracket connected to the door.
  • the appliance further includes a decorative front panel mounted in front of the door and arranged slidably in an essentially orthogonal direction relative to a rotation axis of the door with respect to the body; in this case, the sliding block of each hinge is connected to the decorative front panel.
  • the mounting of the decorative front panel in front of the door can be particularly easy in that it can involve a first step of fixing to the inner face of the decorative front panel that shall be mounted to the door at least one, preferably a pair of, sliding connectors in an upper end region of the decorative front panel and a pair of fastening brackets in a lower end region of the decorative front panel, a subsequent second step of introducing said at least one sliding connector into at least one, preferably a pair of, corresponding vertically elongated guide slots that are arranged in an upper end region of the door of the appliance and that are adapted for slidably guiding said sliding connector during the sliding of the decorative front panel with respect to the door, a subsequent third step of inserting said pair of fastening brackets into a pair of corresponding vertically elongated through-slots which are formed in a lower end region of the door and respectively at a mating position to the corresponding slide of the rotating bracket of the hinge so that the fastening brackets can be readily aligned with the corresponding slides
  • the opposing side faces of the door of the appliance in their lower end regions can comprise an access trough-hole which allows ready access to the respective slide of the hinge and to the screw.
  • the screws can be reached e.g. by a screw driver or a wrench from the outside of the door in order to easily fix the fastening brackets to the slides of the hinges.
  • the fastening brackets can comprise a trimming slotted hole that extends in parallel to the elongated guide structure of the rotating bracket of the hinge when the decorative front panel that carries the fastening brackets is arranged in front of the door.
  • the decorative front panel can be readily vertically trimmed with respect to the door by an easy manual vertical translation of the decorative front panel and hence of the trimming slotted holes with respect to the slides of the hinge before finally fixing the trimming screws.
  • the dishwasher 100 includes a body 105, which has a base 110 for resting the dishwasher 100 on a support surface (not shown in the figure), such as a floor or a support surface of a suitable niche of a piece of furniture of a kitchen wherein the dishwasher 100 can be installed.
  • a treatment chamber 115 with one or more pullout racks, not visible in the figure, for inserting items to be washed (for example, dishes, cutlery, glasses, pots, pans, and the like).
  • the treatment chamber 115 has a front load opening 120, which is closed by a door that includes a door panel 125 and a control panel 130; the control panel 130 may be mounted on top of the door panel 125, in particular flush therewith, so as to be aligned with a top of the body 105.
  • the door 125,130 is rotationally coupled to the base 110 by means of two lateral hinges (only one visible in the figure), generically denoted with the reference 135 (which will be described in detail in the following according to different embodiments of the invention, wherein they will be differentiated with corresponding references).
  • the door 125,130 can rotate with respect to the body 105, around a horizontal rotation axis (raised from the floor), which in the figure extends perpendicularly to the sheet.
  • the door 125,130 can be opened, preferably with a drop-down movement, so as to access the treatment chamber 115 in order to insert the items to be washed and to remove the items being washed.
  • the door 125,130 can be closed, preferably with a pull-up movement, to enable the operation of the dishwasher.
  • the dishwasher 100 shown in the figure is of the full-integrated type, so as to be totally indistinguishable from other pieces of furniture of the kitchen when it is installed.
  • the door 125,130 is completely covered by a decorative front panel 140 (for example, made of wood) with the same appearance as the other pieces of furniture of the kitchen.
  • the decorative front panel 140 can slide in a direction essentially orthogonal to the rotation axis of the door for avoiding any interference of the decorative front panel 140 with any baseboard (not shown) of the kitchen, when the door 125,130 is opened.
