FIELD: electricity. ^ SUBSTANCE: infrared sensor 40 for measuring infrared radiation and light-emitting element 54 are located close to each other under transparent top panel 4a which contains area for heating placed on it article A being heated so that infrared radiation from heated article can be directed to infrared sensor 40. To direct light from light-emitting element to heating area on the top panel 4a there is lightguide section 36a, and light from light-emitting element 54 which has passed via lightguide section 36a is projected to top panel 4a through top hole 36d of lightguide section so that this light is visible inside heating area 35. ^ EFFECT: invention improves possibility to control temperature of heated article depending on infrared sensor readings. ^ 11 cl, 13 dwg |
