Document Type and Number:
Japanese Patent JP2018151111
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a heating cooker which can reliably connect a housing to the ground even a plug is connected in any direction and can prevent occurrence of an electric shock accident at the time of disconnection and a contact failure of a ground line, and a neutral line detection device.SOLUTION: A heating cooker comprises: a metallic cabinet 2 housing a microwave generating means 12; polarity determination means 23 determining wiring connected to a neutral line N out of a plurality of power supply lines 21-1 and 21-2 from a power supply plug 11 to the microwave generating means 12 and connecting the wiring to the cabinet 2; an abnormal voltage detection circuit 44 detecting a voltage between one power supply lines 29-1 being the wiring and the cabinet 2; and a power supply connection circuit 25 cutting-off supply of an AC input voltage from AC power supply PS to the microwave generating means 12 when the voltage detected by the abnormal voltage detection circuit 44 exceeds a predetermined value.SELECTED DRAWING: Figure 2
