Estimating the term…
A housing (1) of an apparatus has a plastics wall portion (2) provided with a plastics panel (4). To make a reliable and visually acceptable connection of the panel (4) to the wall portion (2), the panel is fixed to the wall portion by means of an induction welding process. In this way the connection is resistant to chemical compounds like lotions. Therefore a metal element (8) of electric conducting material having the shape of a closed loop wire is inserted between the wall portion (2) and the panel (4) and subsequently an electromagnetic field is applied in close proximity to the element. Preferably such panel (4) can be used to cover an opening (11) in the wall portion (2) for a display (10) and/or a switch (15) function. To make the housing watertight the element (8) between the panel (4) and the wall portion (2) should surround the opening (3,11).
An apparatus, such as a shaver, a toothbrush, or a kitchen machine, with a housing (1) which is at least partially watertight and which housing has a synthetic resin wall portion (2) on which a synthetic resin panel (4) is fastened, wherein the wall portion (2) has an opening (11) for accommodating a switch (15), the panel (4) is fastened to the wall portion (2) in an RF adhesion process and the panel (2) has an opening which is closed off by a membrane (13), which membrane is provided with an actuator (14) which is present in the opening (11) for the switch (15).
An apparatus, such as a shaver, toothbrush or a kitchen machine, with a housing (1) which is at least partially water tight and which housing has a synthetic resin wall portion (2) on which a synthetic resin panel (4) is fastened, wherein the wall portion (2) has a first opening (3) for accommodating a display and a second opening (11) for accommodating a switch (15), the opening (3) for the display and a second opening (11) for the switch both covered at an inside 95) of the wall portion (2) by said panel (4), said panel (4) being provided with a window (9) of a transparent material situated in front of the opening (3) for the display and with a membrane (13) with an actuator (14) situated in the opening (3) for the switch (15) and an element (8) of an electrically conductive material having the shape of a closed loop is present between the panel (4) and the wall portion (2), by means of which element (8) the panel (4) is fastened to the wall portion (2) in an RF adhesion process.
