A gas heating cooker to be used as a grill or an oven, wherein the blow-off air current of the blowing apparatus blows along the flames of the lower burner to get the hot current to reach far, so that the heating chamber becomes superwide enough to allow a lot of cooking, with the result that the heating operation may be effected with uniform heat distribution in the full face of the heating chamber, and a superior cooking property from even cooking is provided.

Gas combustion apparatus

A high performance automatic temperature control system enables fries and Japanese tempura to be prepared in optimum condition. The temperature of the outer bottom surface of a container being heated is measured by a temperature sensor a given time later. A temperature rise gradient of the temperature sensor established at a given time in the initial stage of heating is used as a temperature correction value peculiar to the container, while a temperature rise gradient of the temperature sensor established after a certain temperature has been reached is used as a temperature correction value for the amount of food being cooked. The former and latter temperature correction values are converted into preset temperature values and serve as operating temperatures for the temperature sensor. When the temperature sensor reaches the operating temperature, the heating rate is controlled to hold the operating temperature. Thus, the system performs automatic temperature control irrespective of the kind of the material, wall thickness and size of the container, by means of the temperature rise gradients of the temperature sensor so as to ensure that the preset temperature and the temperature of the food are equal.
