Abstract: Retractable cord assembly has a power cord for supplying power to an electrical appliance and a plug top with electrical pins connected to one end of the cord for connection with a wall outlet. The power cord is coiled on a spring-loaded spool within the plug top and is extendable from the plug top. The spring-loaded spool provides a retracting force to retract the power cord back within the plug top.

Abstract: A domestic appliance has a heated heat transfer member located in or on its housing and a temperature sensor for measuring the operating temperature of the transfer member. User inputs are provided for selecting an optimized temperature setting for the transfer member. A temperature controller controls the operating temperature of the heat transfer member in response to signals from the temperature sensor to maintain it at or near the selected temperature setting. The power cord of the appliance has a plug top with electrical pins for connection with a wall outlet. The power cord is coiled on a spring-loaded spool within the plug top and is extendable from the plug top. The spring-loaded spool provides a retracting force to retract the power cord back within the plug top.
