전기 레인지
摘要：
본발명은유도가열방식의전기레인지에관한것이다. 본발명은코일, 상기코일과중첩되도록상기코일하측에배치되는금속판및 상기코일과상기금속판사이에배치되며, 상기코일에서형성되는자기장의적어도일부를차폐시키도록이루어지는자기장차폐시트를포함하고, 상기자기장차폐시트는, B, C, N, Si, P, Co, Cu, Zr, Nb 및 Ta 중적어도하나와 Fe로구성된합금을구비하고, 상기합금의적어도일부는결정화된상태인것을특징으로하는전기레인지를제공한다. 본발명에따른자기장차폐시트는종래차폐제보다높은포화자속밀도를가지기때문에, 상기자기장차폐시트를이용하면, 종래전기레인지보다높은출력을낼 수있는전기레인지를구현할수 있게된다.
摘要（英）：

The present invention relates to an electric range with an induction heating method. The electric range comprises: a coil; a metal plate arranged in the bottom of the coil to be overlapped with the coil; and a magnetic field shielding sheet arranged between the coil and the metal plate, and formed to shield at least a part of a magnetic field formed in the coil. The magnetic field shielding sheet has an alloy composed of Fe and at least one among B, C, N, Si, P, Co, Cu, Zr, Nb, and Ta, wherein at least a part of the alloy is crystallized. According to the present invention, since the magnetic field shielding sheet has higher saturation magnetic flux density than that of the existing shielding agent, the electric range of the present invention can realize higher output than that of the existing electric range by using the magnetic field shielding sheet.
