Leakage detecting device for electrical appliance

摘要

A leakage detecting device for electrical appliance is provided with electrodes (17) for detecting a state in which an electrical appliance such as a hair dryer is submerged in water. When the electrodes (17) are in a short-circuited state, relay means (3) is driven to open a contact (7). As a result, supply of the power supply voltage from a commercial power source (1) to the loads such as a motor (15), a heater (16) and the like is stopped so that an accident due to leakage can be prevented in such cases as a case in which the electrical appliance has been dropped into the water.
