Cooking devices with a ringing buzzer are known.

[0003]

In the above-mentioned conventional cooking apparatus, the notification buzzer sounds only once when the detected temperature reaches the set temperature after the control of the combustion amount by temperature is started. This is because if the notification buzzer always sounds when the detected temperature reaches the set temperature, for example,
When cooking tempura, etc., when the food to be cooked is put in the cooking container and the temperature of tempura oil drops slightly below the set temperature, the buzzer sounds when the detected temperature returns to the set temperature. This is because it occurs frequently, causes confusion, and makes usability worse. In addition, when tempura oil is added, the cooking is interrupted and the temperature of tempura oil is increased to the set temperature. However, in the above conventional cooking device, even in this case,
Since the buzzer does not sound, it is not possible to determine whether the temperature has returned to the set temperature, and it is not easy to know when to restart cooking. An object of the present invention is to provide a cooking device having an informing means for informing the user when the detected temperature reaches a set temperature for improving the usability.

[0004]

In order to solve the above problems, the present invention provides a heating source for heating a cooking container containing an object to be cooked and a heating source arranged in contact with the cooking container to control the temperature of the cooking container. A temperature sensor for detecting, a temperature setting means for setting the temperature, a combustion controller for controlling the heating power of the heating source so that the detected temperature becomes the set temperature, and a notification when the detected temperature reaches the set temperature In a cooking device having an informing means for performing, after informing by the informing means,
When the temperature difference between the detected temperature and the set temperature becomes equal to or more than a predetermined value, the notification means again gives a notification when the detected temperature reaches the set temperature next time.

[0005]

The combustion controller heats by the heating source so that the temperature detected by the temperature sensor arranged in contact with the cooking container containing the food to be cooked becomes the temperature set by the temperature setting means. Control the force. The notification means gives a notification when the detected temperature reaches the set temperature, and after the notification, when the temperature difference between the detected temperature and the set temperature becomes equal to or more than a predetermined value due to the addition of the food to be cooked, etc. Notification is given again when the detected temperature reaches the set temperature.

[0006]

When the detected temperature reaches the set temperature, a notification is given, and after this notification, a small amount of food to be cooked is added,
When the temperature difference between the detected temperature and the set temperature is less than the predetermined value and is small, the notification is not issued even when the detected temperature reaches the set temperature again, so the notification does not occur frequently and the user is not confused. Further, when the detected temperature reaches the set temperature, a notification is made, and after this notification, a large amount of food to be cooked is added,
If the temperature difference between the detected temperature and the set temperature is equal to or greater than the predetermined value and is large, a notification is made when the detected temperature reaches the set temperature again, so that the time when the detected temperature returns to the set temperature can be grasped, The user can cook with peace of mind and is easy to use.
