Patent attributes
A state of the current temperature of cooking oil in comparison with the predetermined temperature is figured out and information regarding completion of the on-going cooking and start of the next cooking is easily provided. A display portion 20 largely displays a detected oil temperature state in comparison with the predetermined temperature. As a result, a user can recognize whether the oil temperature is suitable for cooking, thereby it improves utility. Moreover, the display portion displays the oil temperature state and the difference between the predetermined temperature(340° F.) and the detected temperature at the same time. Accordingly, the remaining time to start the next cooking is easily estimated, thereby it improves utility excellently.
