PURPOSE:To increase the amount of food capable of being cooked and improve temperature rising performance in a heating chamber by a method wherein only a part of a wall surface, opposing to the opening of the heating chamber and accommodating an oven plate, is worked by drawing. CONSTITUTION:The wall surface 5 of the heating chamber 1, which is opposing to a door body 2, is worked by drawing so as to be inflated by a dimension A and an electric heater 6 is introduced to the outside of the heating chamber from the upper part of the center of the wall surface 5 while the electric heater 6' is attached to the lower part of the center of the same wall 5. Accordingly, the dimension D of the oven plate may be elongated than the dimension C of the depth of the heating chamber by the inflated dimension A, therefore, the area of the oven plate may be enlarged, a plenty of cooking may be effected once while the inner volume of the heating chamber 1 is not increased so much since the part, accommodating the oven plate 9, is inflated, therefore, the temperature rising speed in the heating chamber is increased, the cooking time of food may be shortened and the heat efficiency of the cooker may be improved. |
