  • Structure for fitting control knobs and a handle onto a control panel of an oven
    Patent number: 6672867
    Abstract: A structure for fitting a control knob and a handle onto a control panel of an oven of the present invention comprises a control panel, a plurality of positioning sets, at least a control knob and a handle, wherein the positioning sets function to insulate the control knob, the handle and the control panel from heat so that deformation of the control knob, the handle, and the control panel due to long duration heating operation of the oven can be effectively prevented. Thus, the use of heat insulation material for making the control knob and the handle can be effectively avoided, and therefore the manufacturing cost can be effectively reduced.
