[Claims for Utility Model Registration] 1. An electrical appliance that is equipped with a power transistor that operates even when the power switch is turned off, and that is configured to use this power transistor as a heater to prevent condensation. 2 A utility model registration request for a configuration in which a power transistor drives a load circuit whose current consumption changes little depending on the mode, and the collector loss of the power transistor is larger when the power switch is off than when it is on. Electrical appliances described in item 1 of the scope.
