The following invention relates to an arrangement for preventing overcooking in a combination of cooking utensils (1A, 101 A) with a lid (1, 101 ) when preparing food. The arrangement comprises an opening mechanism (30, 130), arranged at the lid (1, 101 ), for the regulated manoeuvring of an opening part (3, 106) on the lid (1, 101 ), which opening part cooperates with an opening (4, 102A) in the lid (1, 101 ) when temperatures close to the boiling point are reached in the cooking utensil. The opening mechanism (30, 130) comprises a thermostat (16, 104) with a regulating piston (22, 105) and of the type that has a built-in expanding body acting on the piston (22, 105), the volume of which body is a function of the temperature in the environment of the thermostat. The thermostat is arranged, when temperatures approach the boiling point, to tend to cause the opening mechanism (30, 130) to guide the opening part (3, 106) into an open position in a regulated manner by the regulating piston (22, 105). Furthermore, a spring (14, 113) is comprised that is arranged to tend, working against the thermostat (16, 104), to bias the opening mechanism (30, 130) and the opening part (3, 106) to a closed position at the opening (4, 102A). |
