Abstract: A metallic supplementary pot having superior heat conductivity is newly provided which is attached in the conventional nonmetallic specialized pot which is placed on a turn table mechanism of the microwave oven. When bread is made in the microwave oven, the supplementary pot containing material is attached in the specialized pot before cooking, and the specialized pot is attached to the drive shaft of the turn table mechanism in the oven cavity. Since the tip of the drive shaft is fit into the supplementary pot in this case, a vane member is attached to the drive shaft in the supplementary pot. When cooking is started, the vane member is turned with the rotation of the drive shaft and the material is kneaded into dough. Thereafter, the dough is heated uniformly and in a short time in the supplementary pot, and bread is completed.

Abstract: A cooking appliance in which food stored in a heating chamber is cooked by heating includes a detecting sensor for detecting completion of food to be cooked, a food weight measuring device for measuring weight of food to be cooked stored in the heating chamber, a detector for detecting a variation of the output of the detecting sensor, a comparison circuit for comparing the output of the detector with the output of the food weight measuring sensor, and a controller for controlling the heating operation depending upon on the output of the comparison circuit.
