Heater structure, in particular for examples carried out according to a sandwich structure and examples apparatus comprising such a heater structure

摘要

- household appliances. & br / - the invention relates to a heater structure limited by two rigid elements (2, 3), at least one of which form a heating plate (2), said structure comprising a heating unit including: & br / - at least one resistive element (4) is substantially flat and embedded in a first layer of thermoplastic resin (5), sandwiched between two sheets of an electrical insulator (6a, 6b), said first layer of resin (5) adhering to the sheets of an electrical insulator (6a, 6b) & br / - at least a second layer of thermoplastic resin (7a, 7b) in order to ensure the connection between the heating plate (2) and the heating unit, characterized in that it comprises at least one additional electrical insulating sheet (6c) disposed between the second layer of thermoplastic resin (7a, 7b) and an intermediate layer (7c) of an adhesive material ensuring the connection between one of the sheets of an electrical insulator (6a, 6b) and the sheet of additional electrical insulator (6c). br / - iron.
