Appliance remote touch-control panel with sound system
First Claim
1. A touch control apparatus for a domestic appliance comprising, an elongated box-shaped casing having a rectangular opening in one side wall, a composite touch responsive control panel assembly closing said wall opening, the user'"'"'s side of said panel assembly presenting a continuous uninterrupted surface formed by a flexible sheet of impervious plastic material having deflectable areas, said user'"'"'s side having a plurality of appliance control flexible pads delineated thereon at said deflectable areas with each pad including indicia defining an appliance function, electrically conducting means on said panel assembly in the form of a plurality of single fixed contacts, each of said fixed contacts arranged to interconnect with a movable contact member secured on the inner face of each said flexible pad at a deflectable area providing a series of flexible pad switches, a musical tone generator circuit including a speaker positioned in said casing, each said flexible pad switch being responsive to a preselected deflecting force to the flexible pad to selectively establish an electrical path for the flow of current between different portions of said circuit, and each said flexible pad switch being operative when closed to select a predetermined resistive value in said tone generator circuit causing an electrical pulse to generate a frequency for driving said speaker producing a predetermined audible tone, whereby a distinguishable audible musical tone is obtained for each flexible pad switch to assure the user of the actuation of the preselected appliance function.

Abstract
A remote touch-pad control panel for a domestic appliance coordinated with a sound system for selecting domestic appliance functions whereby a different sound is audible for each function pad touched by the operator. The touch control panel has an imporforate flexible plastic skin coextensive therewith having indicia pads with the skin superimposed on a rigid outer insulating sheet having a plurality of spaced apart apertures arranged in a preselected pattern therein. The flexible skin pads have contacts on their inner surface paired with fixed contacts on an inner rigid sheet spaced by an intermediate frame from the outer sheet whereby a deflecting touch control force through the flexible plastic skin pad establishes electrical connection between the paired contacts to operate the appliance function selected and energize the sound associated therewith.
