を概略つかむことができる。However, in the above-mentioned conventional high-frequency heating device, the temperature display is analog.
Since it was displayed with a temperature range, it was only possible to capture the temperature as an ambiguous concept. On the other hand, cooking has become more diverse and cooking is being done in various households, and there is an increasing demand for more clear temperature. Therefore, digital display may be considered, but various problems described below occur in digital display. That is, when there is only one kind of object to be heated, the temperature change of the object to be heated can be roughly grasped by selectively and continuously digitally displaying the temperature of a representative portion of the object to be heated.

題が生ずる。However, in the case of simultaneously heating a plurality of objects having different heat capacities and / or initial temperatures, for example, a high-frequency heating device has been proposed which can simultaneously heat frozen foods and normal temperature foods and bring them to the ready-to-eat temperature. It became so. In this high-frequency heating device, when heating frozen foods and room-temperature foods, both foods are placed on a placing table, and the placing table is rotated to uniformly irradiate both foods with high frequency, and the temperature is low. When the food, in this case, the frozen food comes near the power supply port having a high high frequency intensity, the rotation is stopped and the frozen food is heated in combination with the centralized heating which intensively heats the frozen food at a high high frequency. At this time, the infrared sensor has a viewing angle near the power supply port, detects the temperature of the food, and displays the temperature on the display unit. In this case, since the mounting table is rotated during the uniform heating, the frozen food and the room temperature food alternately enter the viewing angle of the infrared sensor. Therefore, the display temperature of the heated object on the temperature display may rise,
There is a problem in that the user feels distrustful by falling down.

問題が生じる。When the uniform heating and the concentrated heating are repeated, the food temperature entering the viewing angle of the infrared sensor is different when the heating is switched, so that the display temperature changes greatly. Therefore, there is a problem that the user feels uneasy.

なっても、その温度がそのまま長時間表示されるので使
用者に不安感を与えてしまうという問題があった。Further, when the temperature measurement by the infrared sensor is displayed by focusing on either frozen food or normal temperature food, for example, when focusing on normal temperature food, the normal temperature food is generally eaten earlier than the frozen food. To reach. However, since the frozen food has not risen in temperature yet, heating is continued. Then, even if the normal temperature food reaches the temperature around the time of eating, the temperature is displayed for a long time as it is, and there is a problem that the user feels uneasy.

Therefore, the macro temperature change until the finish of heating is detected, and a consistent and practical temperature that can grasp the progress of cooking at that time is displayed on the temperature display as the current temperature at that time. I did it.
Therefore, the current temperature is a continuous temperature and tends to gradually increase as long as the heating state continues.

Then, the "warm up" key 6 is selected (S101). Next, the detection temperature of 70 ° C. is set with the “heating temperature” key 6 (S
102). Next, when the "Start" key 6 is pressed, it is determined that the heating start operation has been performed, and the process proceeds to the next step. However, if it is determined that the heating start operation has not been performed, the process returns to S101 (S10).
3). If the temperature detected by the infrared sensor 15 in S104 has reached the detection temperature of 70 ° C., it is determined that the temperature has been detected, the heating means 8 is turned off via the control means 17 (S105), and the rotating mechanism 12 is operated. Also turn off (S10

In FIG. 9, it is determined which part of the mounting table 11 the object to be heated 2 exists. As a method for determining the object to be heated 2, the temperature increase value of the temperature data of the second rotation at the same position as the position at which the four temperature data are detected by the infrared sensor 15 of the first rotation of the rotation mechanism 12 is 5 ° C. or more. For example, it is determined whether the object to be heated 2 exists and whether the object to be heated 2 is at the center or at the end of the mounting table 11. If the temperature rise value is less than 5 ° C., the position is judged to be the temperature data of the mounting table 11, and it is judged that there is no object 2 to be heated.

It goes without saying that it is sufficient to flexibly deal with the judgment of how many rotations the first rotation is to be compared, such as the first rotation, and what degree of temperature rise value the temperature should be.
