Wireless electric iron

PURPOSE: A wireless electric iron including a wireless laundry support board is provided to enable a wireless laundry support board capable of transmitting power to evenly transmit power to a large area. CONSTITUTION: An electric iron comprises a wireless power transmission unit and a wireless electric iron unit. An electric iron receiver is put on a charging plate composed of the multiple coils of the wireless power transmission unit. When the electric iron approaches a first side coil from the wireless power transmission unit, power is supplied to the electric iron and MICOM revives by delivering power from a first side to a second side. The wireless power transmission unit senses that current flows to the electric iron in a current sensing unit. When a pulse signal is generated and charged in the electric iron, a pulse signal is applied in the second side, and the second side voltage waves. The voltage change of the second side pulse signal of the electric iron is induced to the first side, and a first side voltage waves according to the pulse signal in a fixed voltage range. A data receiver in the wireless power transmission unit receives data transmitted from a portable device, and MICOM of the wireless power transmission unit processes the received data.
