Abstract
A household appliance device includes an integer number N of row switching elements at a row position i, wherein i is an integer number 1≤i≤N, an integer number M of column switching elements at a column position j, wherein j is an integer number 1≤j≤M, a heating matrix including at least N×M heating matrix elements having positions (i,j), with N+M>2, wherein a heating matrix element at the position (i,j) includes at least one inductor at the position (i,j) and is connected to both the i-th row switching element and the j-th column switching element. At least one switching diode connects at least one of the row switching elements or at least one of the column switching elements to at least one reference potential.
