<p>In accordance with one embodiment, energy savings is achieved in a cooktop by reducing the energy supplied to a burner (314) when no cooking vessel is present. A sensor (120) communicates the presence or absence of the cooking vessel to a controller (110). When the cooking vessel is present, the controller (110) signals a valve (130) by means of a digital-to-analog converter (112) to allow energy to flow to burner (314) unrestricted. When the cooking vessel is not present, the controller (110) signals valve (130) to restrict the flow of energy to burner (314).</p> |
