Electric power conservation film heater

Purpose and idea. A normal electrical cooker has a maximum power of about 6 kW, being a large fraction of the energy consumption in a traditional household. In Denmark the energy used for cooking annually is 1.3 TWh. Of this about 70% (0.92 TWh) is used by the hot plates and 30% (0.38 TWh) is used by the ovens. The purpose of the project is to make hot plates and ovens with alternative heating elements based on thin film technology. Thin films used for high power heaters is a new concept. With the heater being in very close contact with the hot plate and sides of the oven, the appliances can be made more energy efficient, and energy savings of 10-20% should be possible. A main point of the idea is to make the shape of the hot plate conform to the shape of the pot/pan being heated, by making a matrix-heater, composed of many small heaters, where the connections are made with thick film technology. Results of the project will be used in new Electrolux cookers, and will be published at international conference and/or international appliance journals
