Utilizing an interlocking movement and an operation of the switch, a motoris driven under a microcomputer control, and by doing so, the automatic opening and closing movement of a covercan be effected smoothly and stably. Even when a fire occurs at a cooking devicebelow the apparatus, the fire detection meansstops the operation of a circulating fan, and also stops the coverin an open condition, and by doing so, the spreading of the fire can be limited to a minimum, and also an abnormality in the opening and closing of the covercan be indicated at a display portion, and therefore the safety, the durability and the degree of satisfaction of customers can be enhanced.
