There was a problem that the cooking ingredients spilled out during the cooking process without the user noticing what they were doing. Further, since the determination means 9 determines the amount of cooking material inside the pan 1 based on the result of detecting the temperature of the pan 1 by the temperature detection means 8, the outside air temperature of the pan 1 and the temperature detection means 8 and the pan 1 are determined. Occasionally, a misjudgment was made due to the positional relationship with, and the pan 1 was heated more than necessary, and the cooking ingredients were burned more than necessary. In addition, since the pan 1 is constantly heated during the heat retention process regardless of the amount of cooking material in the pan 1, for example, when the amount of cooking material in the pan 1 is large, the heating is insufficient and the amount of cooking material is small. In this case, there was a problem that it was overheated.

Based on the rice cooking process stored in the table, the control means 23 controls the heating control means 13 to start the rice cooking. Next, step
Proceeding to 37, the first judging means 19 judges the amount of cooked rice in the pan 11 based on the output of W-W 1 of the comparing means 18, and determines 38
Proceed to. In step 38, the temperature detecting means 20 detects the temperature of the pot 11 and sends a signal to the second determining means 21 to proceed to step 39. In step 39, the second determination means 21 determines the amount of cooked rice in the pan 11 based on the signal sent in step 38, and the process proceeds to step 40. In step 40, the amount of cooked rice determined by the first determining means 19 in step 37 is compared with the amount of cooked rice determined by the second determining means 21 in step 39. If they do not match, the process proceeds to step 41, and if they match. While proceeding with the cooking process based on the amount of cooked rice, the process proceeds to step 42. If they do not match and the process proceeds to step 41, the amount of cooked rice determined by the first determining means 19 in step 37 and the amount of cooked rice determined by the second determining means 21 in step 39 are compared to obtain the data with the smaller amount. Correction is made, and the process proceeds to step 42 while advancing the cooking process based on the amount of cooked rice. In step 42, the heat retention is started based on the heat retention process stored in the fixed storage means 14. In step 43, the weight detection means 16 detects the weight (W) of the pan 11. Step
In 44, the weight (W 1 ) when there is no cooking material in the pan 11 stored in the storage means 17 and the pan 11 detected by the weight detection means 16
Comparing means 18 and a weight (W) of compared, the process proceeds to step 45 to calculate the W-W 1. In step 45, the heating control means 13 is adjusted on the basis of the result calculated by the comparison means 18 in step 44, and the heating of the heating means 12 to the pan 11 is adjusted.
Return to 43 and repeat this process. In step 33 W-W 1 <
0 or in step 34, W−W 2 > 0. Therefore, when the process proceeds to step 35, the control means 23 controls the heating control means 13 to prohibit energization to the heating means 12 and proceeds to step 46.
In step 46, the buzzer 22a and the LED 22c notify the abnormality.

In comparison, if W−W 2 > 0, it can be detected that more than the maximum cooking material that can be cooked has been put in the pan 11, and it is possible to prevent the occurrence of spillage when starting cooking. Further, the abnormality notification means 22 can notify the user of the abnormality when the pot 11 is not in the correct position or when the pot 11 contains more cooking ingredients than the maximum cooking ingredient that can be cooked. Also, the first
The determination means 19 of the outside temperature of the pan 11 and the temperature detection means 20 and the pan
The amount of cooking material in the pot 11 can be determined without being affected by the positional relationship with the pot 11. Furthermore, the first determination means
Since the amounts determined by 19 and the second determination means 21 are compared and the cooking process is advanced by giving priority to the smaller result, the cooking ingredients can be cooked without burning. In the heat retention process, the first
Since the heating means 12 is controlled on the basis of the result of the determination means 19, the appropriate heat can be maintained regardless of the amount of cooking material.

The comparison means compares the weight (W 2 ) when the maximum cooking material that can be cooked is put in the pan with the weight (W) of the pan detected by the weight detection means, and if W−W 2 > 0 It is possible to detect that more than the maximum cooking ingredients that can be cooked have been put in the pan, and it is possible to prevent the start of cooking and spillage. According to the second aspect of the present invention, when the pan is not in the correct position, or when the pan is filled with more than the maximum cooking material that can be cooked, the abnormality notification means notifies the user of the abnormality. Can inform you. According to the third aspect of the invention, when the determination amounts determined by the first determination means and the second determination means do not match, the one with the smaller determination amount is prioritized and the cooking material is cooked without burning. it can.
さらに第３の発明によれば、保温工程では第１の判定手

を行うことができる。Further, according to the third invention, in the heat retention step, the amount of cooking material is judged by the first judging means, the controlling means controls the heating means based on the result, and the heating means appropriately heats the pot. Therefore, appropriate heat retention can be performed regardless of the amount of cooking material.
