  • the control panel assembly (1) comprises a panel body (2) attached to an electronic control card (3) by means of a separator (4) on the inner side of the assembly.
  • the separator (4) mounted directly in front of the electronic control card (3) provides protection to ensure impermeability against liquid passage and associated electronic card damages.
  • the separator (4) is positioned behind the panel body (2) of the control panel assembly (1) while a beam collector (5) with a plurality of light channels (17) is disposed between the panel body (2) and the separator (4).
  • the beam collector (5) is positioned in front of the separator (4) to guide light beams through light channels (17) so that the specific areas on the control panel body (2) are illuminated.
  • the touch buttons (6) when pressed, transfer the applied force to tactile switches (9) of the electronic control card (3), upon which the function chosen by the user is executed.
  • the present invention overcomes the problem of liquid leakage through the intermediate spaces in between and around the touch buttons (6) to the electronic control card (3) by way of placing a separator (4) in front of the card, the separator (4) comprises an improved structural design with button recesses (10) receiving and mechanically communicating with the touch buttons (6) without creating water flowing paths in the direction of the electronic control card (3).
  • the separator (4) is positioned in front of the electronic control card (3) to be functioning as a physical separator, light carrier and liquid leakage barrier preventing liquids reaching to the circuit elements of the electronic control card (3) as will be delineated hereinafter.
  • the separator (4) is made of a non-transparent material, it additionally acts so as to intercept light beams from different parts of the electronic control card (3) and prevent them to be reflected at the inner regions of the control panel assembly (1).
  • the separator (4) when the user presses a button dedicated to execute a specific function of the household appliance, an indication in the form of an illuminated portion appears proximate the pressed button.
  • the light beams are directed from the light source (11) on the electronic control card (3) to the panel body (2) through the beam collector (5) to provide an indicator of the specified function to the user.
  • the beam collector (5) mounted on the separator (4) therefore ensures propagation of the light beams homogenously through lights channels (17) without reflections along other portions of the surface area of the electronic control card (3) until the light beam reaches to the outer wall of panel body (2).
  • connection extensions (8) which are tubular elongated body portions integral with the touch buttons (6), into the button recesses (10) of the separator (4).
  • the connection extensions (8) lean on engagement portions (7) providing the mechanical interaction between the electronic control card (3) and the touch buttons (6) by means of the connection extensions (8), pressing on the engagement portions (7) and the latter in turn applying an operating force to the tactile switches (9). Therefore, the engagement portions (7) of the separator (4) press on the respective tactile switches (9) of the electronic control card (3).
  • the installation of the touch buttons (6) into the separator (4) is ensured by the engagement of the latching members (14) of the touch button (6) with a supporting enclosure (16) of the separator (4) so as to have a mutually interengaged connection.
  • the latching members (14) are positioned within the inner region of the touch buttons (6) to be oppositely extending neighboring the outer surfaces of the supporting enclosure (16), in contact with upper and lower enclosure plates (19) thereof.
  • the mating relationship of the respective parts, i.e. the latching members (14) and the supporting enclosure (16) serve for providing a leakage barrier preventing liquid flow to the electronic control card (3).
  • the upper and lower parts of the supporting enclosure (16) in the form of opposite enclosure plates (19) as seen as arm portions in the cross-section of Fig. 7, slightly moving away from each other starting from the planar body portion of the separator (4) to form a larger outer opening ensures that liquids leaking through the small opening between a given touch button (6) and the panel body (2) portion above the button will be trapped by the upper enclosure plate (19) as seen in Fig. 7, because the latter extending in an inclined manner with respect to the horizontal axis prevents liquid flow in the reverse direction, i.e. in the direction of the outer portion of the touch button (6), which would otherwise allow liquids to reach the region around the connection extension (8) and subsequently the engagement portion (7) and the respective tactile switch (9).
  • each touch button (6) comprises positioning extensions (15) ensuring appropriate positioning relative to a supporting enclosure (16).
  • connection extension (8) positioned centrally within the inner region of the touch button (6) is responsible for imparting a triggering movement to interact with the respective tactile switch (9) of the electronic control card (3).
  • the beam collector (5) is connected to the separator (4) to guide the light from the light source (11) on the electronic control card (3) towards a limited surface area on the wall of the panel body (2), illuminating the buttons being pressed as an indication of the chosen function for the user.
  • the beam collector (5) is mounted on the separator (4) such that the light channels (17) fit into the apertures (18) of the separator (4), extending outwardly towards the panel body (2) and directing the light beam homogenously to the surface area of the front wall of the panel body (2).
  • neighboring light channels (17) are preferably separated from each other by an additional antireflection plate (12) to prevent light leakage. This is advantageous as an additional measure because it might happen that light from the light sources (11) leaks out through a small gap where the light channels (17) enclose the light sources (11).
  • a separator (4) is interposed between the electronic control card (3) and the panel body (2).
  • the separator (4) comprises button recesses (10) receiving the touch buttons (6) and the touch buttons (6) mechanically interacting with the electronic control card (3) by means of tactile switches (9) on the electronic control card (3).
  • the touch button (6) comprises an inner connection extension (8) extending in the direction of an engagement portion (7) that is resiliently connected with the separator (4).
  • connection extension (8) is in the form of an elongate body portion mechanically interacting with the tactile switch (9) by way of the engagement portion (7) resiliently pressing on the tactile switch (9).
  • the touch button (6) comprises flexible arms (13) extending out on upper and lower parts of the touch button (6) and resiliently leaning on the wall of the separator (4).
  • the touch button (6) mechanically communicate with the button recess (10) such that at least two latching members (14) of the touch button (6) interengage with a supporting enclosure (16) of the button recess (10) so as to have a mutually interengaged connection.
  • a beam collector (5) is fitted to the separator (4) between the panel body (2) and the separator (4).
  • the beam collector (5) comprises a plurality of light channels (17) to guide light beams from lights sources (11) on the electronic control card (3).
  • neighboring light channels (17) are separated from each other by an antireflection plate (12) extending out from the separator (4).
