Radiation cooker is a device that cooks food by using radiant heat generated by heating the heating element. Ceramic glass is covered on the upper surface so that the flame is not exposed to the outside. In recent years, the use is gradually increasing, and active research on it is in progress.

One example is a radiating cooker that uses a heating coil as a heating element and generates heat by heating the heating coil. Such a radiating cooker has been developed in the past and is mainly installed and used in a condominium or a business.

However, the radiating cooker using the heating coil as described above had a number of advantages, but it was not easy to install or use in a general household due to the poor economic efficiency due to the large amount of electricity consumed for heating the heating coil.

Recently, a lot of research has been conducted by developers in this field to develop a gas radiation cooker that uses a relatively inexpensive gas instead of electricity to heat a heating element. By adjusting the amount of fuel gas to control the radiation intensity of the heating element, the radiation area of the heating element is always fixed, there was a problem in terms of radiation efficiency.

The object of the present invention devised in view of the above problems is to provide a radiation intensity control apparatus for a radiation burner for a gas radiation cooker which is adapted to increase the radiation efficiency by controlling the radiation area of a heating element when the radiation intensity is controlled.
