Further, a time pulse control circuit 9 necessary for the microcomputer 8 to measure IJ[l ripening time is connected to the terminal of the microcomputer 8, and a display means 4 is also connected thereto. IO is a high frequency generation means.

The ROM section 8C of the microcomputer 8 has a function that counts the time signal taken in through the pulse generation circuit 9 and measures the heating time. It has the function of 1llll. When the cancel button 5 ( ) is pressed, the contents stored in the RAM section 8d are erased, and when the heating start switch 58 is pressed, the heating contents stored in the RAM section 8d are erased. 11 Te 1 High frequency generation means 10
It also has the function of controlling the heating of these Q~) based on the heating time measured separately. Furthermore, the display means 4 displays the progress of the heating contents in progress, for example, the progress of the already set heating time and 11,! Knee... It is a se that has the function of decreasing h+ and displaying it.

Rotary encoder 7 (J mini 1 in 8 (7) 8 1 river, ' is connected to rotary encoder 7a, 7b in Fig. 5.
