Cooking device

摘要

A cooking device includes an infrared ray sensor (1) disposed to sense infrared radiation from food obliquely from the above. Infrared ray sensor (1) includes a printed circuit board (36), a light receiving portion (3), a photointerrupter (10), and a chopper (8). The chopper includes a horizontal vane portion (39) and a vertical vane portion (40). The chopper is disposed between the light receiving portion (13) of infrared ray sensor (1) and food (31) such that the vertical vane portion (40) passes between the light emitting device (29) and light receiving device (30) of photointerrupter (10) and that horizontal vane portion (39) passes between the light receiving portion (3) of infrared ray sensor (1) and food (31) when chopper (8) rotates. Thus, an improved microwave oven having a reduced occupied area which can be manufactured less costly can be provided. <IMAGE>
