In addition, when the cooking is completed, the gauge is displayed as a blinking signal so that the user can clearly recognize that the cooking is completed. Further, although not shown, a separate alarm means (not shown) The finished dish will be ready to be eaten before eating.

On the other hand, the calculating unit 22 calculates a water reduction amount corresponding to the set humidity value. The calculating unit 22 stores data on the water reduction amount corresponding to the set humidity value, and the user inputs the set humidity value The amount of water reduction is selected and the amount of water reduction is calculated.

The sensing unit 26 is configured to measure the amount of water contained in the water tank 10 and any sensor capable of measuring the amount of water contained in the water tank 10 may be applied.

As the sensing unit 26, one or more of a water level sensor for measuring the water level change of the water contained in the water tank 10, a volumetric sensor for measuring the volume change of water, and a mass sensor for measuring the water mass change can be applied.
