ABSTRACT:
A high frequency cooker which detects a sound generated upon boiling of a material to be heated in response to the material being heated and switch as to a cooking mode in response to the detected signal of that sound. The cooker comprises a heating section for heating a material to be heated, a sensor for detecting a sound generated from the material to be heated upon boiling of the material to be heated, and a control section for controlling the heating section in response to the detected sound. The cooker can sense the sound of the material to be heated and can switch automatically from a cooking mode to a warm mode even by only making a single function selection. An optimum cooking state of the food can be maintained, and unnecessary power loss can also be prevented.
