Disclosed are an induction heating device and a vessel sensing method of the induction heating device. The induction heating device determines whether a vessel is present in a heating region corresponding to a working coil using two sensing methods. In more detail, the induction heating device determines whether a vessel is present in the heating region by sequentially performing first vessel sensing based on a resonance current value of the working coil and second vessel sensing based on a sensing value obtained by a vessel sensor. It is possible to precisely sense a vessel by applying the two sensing methods as described above.

Induction heating device and vessel-sensing method of the induction heating device

An induction heating device capable of preventing a fuse breaking phenomenon that occurs when a user preheats an empty vessel by determining whether or not a load is present in the vessel, and a method for controlling an induction heating device. In order to prevent a rapid rise in temperature of a vessel occurring in process during which a user preheats an empty vessel using an induction heating device and a fuse breaking phenomenon resulting therefrom, a controller of the induction heating device may determine whether or not a vessel placed on a working coil is an empty vessel in a vessel heating process, that is, whether or not a load is present in the vessel.

Induction heating device and method for controlling induction heating device

A network system is provided. The network system includes: at least one component selected from an energy receiving unit receiving energy and an energy management unit managing the energy receiving unit. The energy receiving unit or the energy management unit receives energy rate related information; an energy usage amount or a usage rate of when the component is controlled on the basis of at least the energy rate related information is less than that of when the component is controlled without the basis of at least energy rate related information; if the energy rate related information is high cost information, a function of one component constituting the energy receiving unit is limited; and an operating time or an output of the energy receiving unit is adjusted in correspondence to the limited function of one component.

Network system

A mobile terminal is disclosed. The mobile terminal can transmit/receive information or a signal to/from a cooking apparatus, improve user convenience, remotely monitor a state of the cooking apparatus, and receive a control command with respect to the cooking apparatus.
