HIGH FREQUENCY HEATING COOKER

PROBLEM TO BE SOLVED: To prevent insulation deterioration and an electric shock caused by attachment of water from outside to a temperature excessive rise prevention device installed on a side surface of a heating chamber.SOLUTION: A high frequency heating cooker includes: a magnetron 31 (a high frequency generation device) which supplies high frequency to a heating chamber 1; cooling means 32 which cools the magnetron 31; an air intake port 14 which is provided at a side surface of a heating chamber 1 and which guides the air after cooling the magnetron 31 by the cooling means 32 into the heating chamber 1; an exhaust port 12 which is provided on a side surface of the heating chamber 1 facing the air intake port 14 in the heating chamber 1; an exhaust air guide plate 11 arranged outside of the side surface of the heating chamber 1 having the exhaust port 12 at a position facing the exhaust port 12, and whose upper end is fastened to the heating chamber 1; and a temperature switch 13 (a temperature excessive rise prevention device) which is arranged on the exhaust air guide plate 11 and at a position facing the exhaust port 12. The exhaust air guide plate 11 forms a concave shape toward the exhaust port 12 on the portion of the temperature switch 13, and includes an eaves structure above the temperature switch 13.
