どの不具合がなく、加熱室内温度を迅速に設定値Ｔｃに
至らせることができる。In particular, we have addressed the fact that the overshoot of the temperature in the heating room varies depending on the weight of the food, as shown in Figure 5.
The predetermined value Torr is changed according to the weight of the food, so the pressing amount against overshoot is accurate, meaning there is no problem such as excessive pressing amount or insufficient pressing amount, and the temperature in the heating room can be maintained. The set value Tc can be quickly reached.
したがって、良好な出来具合の調理が可能である。Therefore, it is possible to cook food with good quality.
