As shown in the figure, the cooking utensil 1 includes a cooking chamber 2 for storing a cooking product, a cooking unit 3 (microwave supplying unit) for cooking the cooking product, and a humidity sensor for detecting the relative humidity of the cooking chamber 2. The humidity detecting means 4 is composed of the above, and the control means 5 for controlling the cooking means 3 based on the information from the humidity detecting means 4. In order to automatically cook with such a structure, it is necessary to know the weight of the food, the initial temperature, and the like. For that purpose, the time T from the time when the power is turned on until the output of the humidity detecting means 4 reaches a certain humidity is measured, the weight of the food is estimated based on this time T, and at this time, a constant k peculiar to each food is obtained. The optimum cooking time was the time multiplied by.

In the microwave oven, as shown in FIG.
As shown in FIG. 5, the cooking utensil 1 includes a cooking chamber 2 in which the position of a cooking dish 16 for accommodating a dish is variable, a shelf 15 for placing the cooking dish, a cooking means 3 for cooking the dish, and a cooking chamber 2 inside. The temperature detecting means 4a is composed of a thermistor or the like for detecting the temperature, and the control means 5 is arranged to control the cooking means 3 based on the information from the temperature detecting means 4a. With such a configuration, automatic cooking was possible. Taking oven cooking as an example, menus include cakes, apple pies,
There were pizza, cookies, butter rolls, cream puffs, gratin, foil grill, hamburger, meat grill, barbecue, fish grill. In other words, it was divided into the above 12 menus on the operation unit of the microwave oven. Moreover, the position where the cooking dish is placed is different in each menu, and the three positions of upper, middle, and lower are determined by the menu. For example, for pizza, the plate position is below,
Cream puff is in the middle. The user first decides a menu, sets a cooking dish on which food is placed at a position corresponding to the menu, and presses the cooking start key to start cooking. After that, the control means 5 was equipped with a control sequence program for controlling the cooking means 3 by an automatic cooking sequence corresponding to the menu. In this automatic cooking sequence, the temperature detecting means 4a heats the time T from the start of cooking until the temperature in the cooking chamber reaches a certain temperature by a constant K corresponding to the selection menu. One of the points of automatic cooking is that the time T changes depending on the weight of the food. Further, the constant K has been determined to be the optimum value for the menu by conducting many cooking experiments.

In such a conventional cooking utensil, the time from the start of cooking until the humidity in the cooking chamber reaches a certain value is measured, and the time is multiplied by a constant K determined for each category. Since the cooking time has been decided as the cooking time, the operation keys are required in the operation unit for the number of categories. There was also a considerable variation in the cooking results. For example, there is no problem if the reheats of "rice" and "miso soup" are divided into different categories, but if they are made into the same category, the result will differ depending on whether the constant K is adjusted to "rice" or "miso soup". "It was too hot, and" miso soup "was lukewarm. In order to solve this, it is sufficient to subdivide the categories, but the number of operation keys is increased by the number of subdivisions, and there is a problem that usability becomes very poor. The same applies to the microwave oven, and since the automatic cooking sequence corresponding to the menu is provided, the automation for the menu has been realized to some extent. However, since there are many menu keys for selecting a menu, there is a problem in that it is very inconvenient in terms of usability.
