The electromagnetic induction method is a method in which a voltage is induced and an electromagnetic induction phenomenon in which a current flows when a magnetic field is changed around a conductor through which electricity flows.

The magnetic resonance method can transmit power according to a wireless power transfer in which electromagnetic waves travel from a transmitter to a receiver through an electromagnetic field when the transmitter and the receiver resonate at the same frequency. The transmitting coil of the transmitter can have a predetermined resonance frequency, and receives energy from the power source. Electromagnetic waves can be generated and a magnetic field can be formed accordingly. At this time, induced electric power may be generated in the reception coil of the receiver by the magnetic field

Therefore, the cooker can carry out the removable input device, receive feedback in real time, and control it remotely.

On the other hand, when the cooker uses the smart device during the cooking process, there is a problem that the device needs to be checked from time to time to view trivial information such as cooking time.

Also, it is difficult to scroll the smart device screen because the cooker's hand is filled with water or material, and the screen frequently turns off.

However, according to an embodiment of the present invention, the main information is transmitted to the detachable input device and is displayed on the detachable input device so that intuitive confirmation is possible.

In addition, the Always On feature allows the removable input device to be turned on continuously, allowing the user to check the cooking status even when the smart device is turned off.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It should be understood that various modifications may be made by those skilled in the art without departing from the spirit and scope of the present invention.
