High frequency heating apparatus

A high frequency heat-cooking apparatus equipped with an oven hood, comprising:

• a heating chamber for storing thereinto a food product;
• an appliance main body having the heating chamber;
• a magnetron for generating high frequency electromagnetic waves to the heating chamber;
• a cooling fan for cooling the magnetron;
• an operation panel having various sorts of operation switches, which is provided on one side wall of a front surface of the heating chamber;
• a control means for controlling a supply of electric power to the magnetron, which is provided within the operation panel;
• an air intake port for sucking generated gas from another heat-cooking apparatus installed under the appliance main body;
• an air exhaust fan for exhausting the generated gas sucked from the air intake port;
• an air exhaust port through which the generated gas is exhausted;
• and
• a first detecting apparatus and a second detecting apparatus, for detecting the generated gas,
• wherein said air exhaust fan is automatically activated when said first detecting apparatus detects combustion gas generated by said another heat-cooking apparatus, while said control means stops the supply of electric power to the magnetron when said second detecting apparatus detects high-temperature gas.
