  • Patent number: 6007242
    Abstract: A cooking device includes an infrared ray sensor disposed to sense infrared radiation from food obliquely from the above. Infrared ray sensor includes a printed circuit board, a light receiving portion, a photointerrupter, and a chopper. The chopper includes a horizontal vane portion and a vertical vane portion. The chopper is disposed between the light receiving portion of infrared ray sensor and food such that the vertical vane portion passes between the light emitting device and light receiving device of photointerrupter and that horizontal vane portion passes between the light receiving portion of infrared ray sensor and food when chopper rotates. Thus, an improved microwave oven having a reduced occupied area which can be manufactured less costly can be provided.
