PURPOSE:To rise temperature in a heating chamber and permit to utilize a fanmotor of small size and light weight by a method wherein heating devices are provided near the bottom surface and the upper surface of the heating chamber while a hot-air circulating fan is provided in a sub heating chamber neighboring the heating chamber. CONSTITUTION:The heater 4a for heating grill and oven is provided near the upper surface of the heating chamber 2 and the heater 4c exclusive for heating the oven is provided near the bottom surface of the heating chamber 2. The sub heating chamber 6, accommodating the fan 7 for circulating the hot air in the heating chamber 2, is provided neighboring to the rear wall 9 of the heating chamber while a motor 8 for driving the rotation of the fan 7 is mounted at the outside of the sub heating chamber 6. When the fan 7 is rotated, the hot air in the heating chamber 2 is circulated through suction opening 10 and discharging opening 11 for circulating hot air, which are provided on the rear wall 9. According to this method, the heating chamber is heated directly by the heaters, therefore, the heat loss of the cooker may be reduced. |
