Definitions

  • the present invention relates to a household appliance which prevents electrostatic charges from attaining the control cards.
  • Household appliances such as dish washers, washing machines, ovens, refrigerators, etc. are equipped with control panels over which are placed the control buttons that enable a user to make various adjustments.
  • Control buttons are connected to the control cards located behind the control panel, and commands are transmitted to these control cards through the medium of buttons.
  • Control panels and control buttons which are in general made of an insulating material such as plastic, are fabricated in some models with a conductive material like metal or painted with a conductive paint to give them a metallic look so as to obtain visual amelioration.
  • buttons are either fabricated with a conductive substance like metal or given a metallic look through coating with a conductive paint, these buttons also become conductive. Electrostatic charges accumulated on a user can thus be transmitted to the control cards once the user touches the buttons. It is observed that control cards deteriorate for this reason.
  • JP2002039537 relates to a control panel placed over a cooking appliance. There is an insulating layer to prevent the transfer of electrostatic charges from the user to the control card when he presses on or around the buttons over the control panel.
  • JP4025101 describes a regulator containing an insulating material in order to prevent the transfer of electrostatic charges between the control panel and the main body.
  • German Patent Application Number DE3204020 and the United States Patent Application Number US6091082 explain similar applications wherein an insulating material is incorporated to prevent the transfer of electrostatic charges between the zone that the user touches and the sensitive zones (such as PCB, control cards, etc.) which may be damaged by electrostatic charges.
  • US 2005/0178167 A discloses a household appliance comprising a panel, a control button being fixed onto the panel and a control card which is situated on the back side of the panel and to which the control button is connected.
  • the object of the present invention is to design a household appliance wherein the transfer of electrostatic charges is prevented between the user and the electronic circuit cards through the medium of buttons that contain conductive materials.
  • the household appliance designed to attain the objective of the present invention is described in the claim attached herewith.
  • the control cards are attached on the panel with dielectric screws.
  • these screws block the transfer of electrostatic charges between the control buttons and the control cards.
  • insulation is secured through the use of dielectric screws, there is no need for any other insulating material between the control buttons and the screws.
  • FIG. 1 - a schematic view of the household appliance
  • Figure 2 - a perspective view of the panel
  • Figure 3 an internal view of the panel
  • the household appliance (1) which constitutes the object of the present invention includes a panel (2), control buttons (3) which are fixed on the panel (2), a control card (5) on the back side of the panel (2) and connected to the control buttons (3), and at least one screw (6) made of dielectric material and which fixes the card (5) to the panel (2).
  • the control card (5) which is on the back side of the panel (2) is fixed onto the panel (2) with screws (6).
  • the control card is equipped with a shaft (4) onto which are fastened the buttons (3); the shaft (4) passes through a hole on the panel (2) and comes out at the front side of the panel (2).
  • the button (3) is attached to the shaft (4) after the control card (5) is fastened to the panel (2). Transmission of commands to the control card (5) is ensured through the medium of this shaft (4).
  • the button (3) When the control card (5) is fixed on the back side of the panel (2), the button (3) is fastened to the shaft (4) emerging from the front surface of the panel (2). Fastened to the panel (2), the button (3) covers the screw (6) heads which are over the panel (2) and comes therefore into contact with the screw (6) heads.
  • the panel (2) is made of an insulating material such as plastic, whereas, due to visual amelioration concerns, the control buttons (3) fabricated with a conductive substance such as metal or given a metallic view through painting with a conductive paint. The transfer of static charges between the control card (5) and the button (3) is become prevented by means of the used dielectric screws (6).
  • the button (3) is fixed and mounted over the shaft (5), leaning upon dielectric screw (6) heads; therefore, although their metal coated surfaces touch the panel (2) and/or the screw (6), which are fabricated with insulating material, the static charge is not transferred to the control card (5).
  • the household appliance (1) which constitutes the object of the present invention, wherein the card (5) is mounted onto the panel with a screw fabricated with an insulating material like plastic, does not necessitate the use of any special attachments to ensure insulation between the buttons (3) and the screw (6). This not only provides cost savings in component parts but also reduces the time necessitated for production and assemblage.
