Title: Heating and cooking device
Inventor: MATSUSHIMA KAZUFUMI
IPC: F24C7/02
Filed: 1990-02-26
Abstract: PURPOSE:To prevent a user from setting a cooking completion time to a shorter time than that required for a cooking operation by a method wherein the time required for cooking an inputted volume of food from a present time is displayed as an adjustment completion time at a display part. CONSTITUTION:As an amount of food to be cooked is inputted by a user through an amount inputting means 9, a control means 11 preliminarily sets a time when a time required for a cooking of food of the amount elapses from a present time as a cooking completion time and then a cooking completion time is displayed on a display part 5. Accordingly, the user can know the cooking completion time through this display. When the cooking completion time desired at the beginning is near to the present time, a starting operation is carried out as it is. Then, the cooking is completed as the preliminary set time. If the desired cooking completion time is advanced ahead the preliminary set time, the reservation time setting means 8 is operated and the preliminary set cooking completion time is varied. After this operation, if the starting operation is carried out, the cooking is completed at the newly set cooking completion time.
