Thermal efficiency plate used in cooking range and cooking range with thermal efficiency plate

The utility model discloses a thermal efficiency plate used in a cooking range. The thermal efficiency plate is used for absorbing heat energy and reflecting the energy to the bottom of a container when a combustion engine heats the container during operation, the container is heated by virtue of an auxiliary combustion engine, and an air hole through which hot flow generated by the combustion engine passes is formed in the thermal efficiency plate. The hot flow generated by the combustion engine can return to the air hole along the thermal efficiency plate while ascending to the bottom wall of the container. The cooking range comprising the thermal efficiency plate comprises the combustion engine, the container and a bearing piece, wherein the bearing piece comprises a heating opening; the container is tightly pressed against the bearing piece; the thermal efficiency plate is erected between the container and the bearing piece; a flue in which the thermal efficiency plate is placed is formed in the bearing piece; and a smoke outlet leading to the outside of the bearing piece is formed in the bottom wall of the flue. In the heating process, high-temperature gas generated by the combustion engine ascends and returns when meeting the bottom wall of the container, the high-temperature gas flows along with the thermal efficiency plate, the process of returning the high-temperature gas is added, and the heat energy heating efficiency is improved.
