ABSTRACT:
A clothes washing machine is specially adapted to protect pocket-portable electronic devices from damage. A basket is aligned with an opening for receiving clothes to be washed. A door covers the opening during washing of clothes. An electromagnetic loop is positioned at the periphery of the opening so that all clothing loaded into the clothes washing machine passes through the electromagnetic loop. The electromagnetic loop is also positioned so that no permanent ferrous structures of the clothes washing machine are located between the electromagnetic loop and the opening. A detector circuit is coupled to the electromagnetic loop for generating an electronic detection signal in response to a predetermined change in an electromagnetic characteristic sensed across the electromagnetic loop corresponding to a pocket-portable electronic device being present at the opening. A washing machine controller coupled to the detector circuit responds to the detection signal to generate an alarm and to inhibit a washing cycle (e.g., introduction of water into the basket) until a user provides a manual override signal to the washing machine controller.
