Cooking apparatus such as fryer or the like for frying food

A cooking apparatus for frying food having an oil tank filled therein with cooking oil to be maintained in a heated condition by a heating means, the cooking apparatus comprising:

• a housing having said oil tank disposed therein;
• detection means for detecting an amount of vapor, including a first peak and a second peak amount of vapor, rising from the food after the food has been placed into the heated cooking oil, said detection means having a vapor detecting element mounted on said housing and located above the surface of said cooking oil to be directly exposed to the vapor rising from the food;
• first means in said housing coupled to said detection means for determining whether or not said detected amount of vapor has reached the second peak thereof after having reached the first peak thereof, and for generating a decision signal if the second peak has been reached after the first peak;
• and
• second means in said housing coupled to said first means for determining if said detected amount of vapor has reached a predetermined amount of vapor after having received said decision signal, and for determining frying completion of the food if the predetermined amount has been reached.

A cooking apparatus for frying food having an oil tank filled therein with cooking oil to be maintained in a heated condition by a heating means, the food being frying materials of which an interior portion needs not to be heated, the cooking apparatus comprising:

• a housing having said oil tank disposed therein;
• detection means for detecting an amount of vapor rising from the food after the food has been placed into the heated cooking oil said detection means having a vapor detecting element mounted on said housing and located above the surface of said cooking oil to be directly exposed to the vapor rising from the food;
• and
• determining means in said housing coupled to said detection means for determining whether or not said detected amount of vapor has reached a peak thereof, and for determining frying completion of the frying materials of which the interior portion needs not to be heated, when said peak has been reached.

A cooking apparatus for frying food having an oil tank filled therein with cooking oil to be maintained in a heated condition by a heating means, the cooking apparatus comprising:

• a housing having said oil tank disposed therein;
• detection means for detecting an amount of vapor rising from the food after the food has been placed into the heated cooking oil, said detection means having a vapor detecting element mounted on said housing and located above the surface of said cooking oil to be directly exposed to the vapor rising from the food;
• first means in said housing for generating a reference signal indicative of a predetermined amount of vapor, and
• second means in said housing coupled to said detection means and said first means for generating an output signal in comparison of said detected amount of vapor with said reference signal.
