理物の味、形などを劣化させることを防止できる。EFFECTS OF THE INVENTION As described above, according to the present invention, when the temperature of the pot is kept constant, the energization to the lid heating part is maximized when the temperature of the lid is lower than a certain temperature φ 1 , and the energization rate is high when the temperature is high. Because the temperature of the lid can be kept at a certain constant temperature φ 2 by making the value smaller, even if the user opens and closes the lid during heat retention, it becomes difficult for the dew to adhere to the inside of the lid and It is evaporated by the heat of the lid heating part. Furthermore, even if the lid is cooled rapidly to make it easy to get dew, it is heated with full power and does not get dew. As a result, it is possible to prevent dew from falling on the food in the pot and deteriorating the taste, shape, etc. of the food.

手段とを備えた調理器。Claim: What is claimed is: 1. A pot for putting food to be cooked, a bottom heating part for heating the bottom part of the pan, a body heating part for heating the side part of the pan, a lid for closing the pan, and a heating for the lid. A lid heating part, a bottom heating part driving means for energizing the bottom heating part, and a body heating part driving means for energizing the body heating part,
A lid heating unit driving means for energizing the lid heating unit, a pot temperature detecting unit for detecting the temperature of the pot, a lid temperature detecting unit for detecting the temperature of the lid, the lid temperature detecting unit and the pot. By inputting a signal to the temperature detecting means and controlling the bottom heating part driving means and the body heating part driving means so that the temperature of the pot becomes a certain temperature θ 1 in the heat retaining step, the temperature of the lid has a certain temperature. When φ 1 or less, the lid heating unit driving means is controlled so that the lid heating portion is energized to full power, and when the lid temperature is a certain temperature φ 1 or more, the lid heating portion driving means is operated. Control to reduce the energization rate to the lid heating section,
A cooking device comprising: a control unit that controls the temperature of the lid to be a constant temperature φ 2 .
