  In particular, the second invention is a human body detection means for transmitting either or both of the first human body detection means and the second human body detection means of the first invention to the heating control means. For example, by using an ultrasonic sensor, the same effect as that of the first invention can be obtained, and the heating control means can perform the determination quickly.

  In the third invention, in particular, whether or not there is a person emitting infrared rays in a predetermined band for either or both of the first human body detecting means and the second human body detecting means of the first invention. By using, for example, a pyroelectric sensor as the human body detecting means for transmitting the heat to the heating control means, the same operational effects as in the first invention can be obtained, and the heating control means can quickly make a determination.

  In particular, the fourth invention is provided with a sensitivity changing means capable of changing the amount of information detected by either or both of the first human body detecting means and the second human body detecting means of the first to third inventions. Thus, even if the amount of information detected by the first human body detecting means using the photo sensor and the second human body detecting means varies depending on the environment where the cooking apparatus is installed, for example, the surrounding color, it can be adjusted. And a stable signal can be obtained.

  The fifth aspect of the invention is particularly the same operation as any of the first to fourth aspects of the invention by making a computer function as all or part of any one of the first to fourth aspects of the invention. An effect is obtained.
