The present invention relates to a cooking appliance including: a cooking chamber surrounded by a cooking chamber wall and a door; a heating means disposed in the cooking chamber for emitting heat; a combustion pipe, which is a pipe formed so as to be hollow in order to surround the heating means, and which is heated by the heating means so that radiation heat therefrom is provided to the central part of the cooking chamber; a combustion space, which is a space formed between the heating means and the combustion pipe, and in which a contaminant is thermally decomposed by heat from the heating means; a blowing fan which takes air into the cooking chamber and moves a part or the entire mass of the air that has been taken in through a connection pipe to the combustion space; the connection pipe which connects the combustion pipe with the blowing fan so that the communication of the air is possible; and an outlet through which the gases that contain water vapors in the combustion space are discharged out of the cooking appliance. According to the cooking appliance of the present invention, the heating means heats the combustion space so as to thermally decompose contaminants. Further, the radiation heat is provided to the cooking chamber through the combustion pipe so that food is heated with high energy efficiency. |
