Abstract: A system to transmit and receive wireless power, a terminal device, a management server, and a wireless power transmission apparatus may use non-radial wireless energy transmission technology to generate a resonant frequency in resonators and charge a device. The terminal device may receive the wireless power to perform charging by non-contact energy transmission.

Abstract: A washing machine including a drying apparatus. The washing machine including the drying apparatus quickly dries wet laundry by efficiently condensing and adsorbing vapor from humid air of high temperature flowing from a water tub during a drying-mode operation. The drying apparatus includes a condensing duct and a blower duct respectively mounted on a rear surface and an upper surface of the water tub. The condensing duct has an ultrasonic atomizing unit, a condensing unit and a water adsorption unit therein, while the blower duct has a blower fan and a heater therein. An inner space of the condensing duct is partitioned into a first condensing path, a second condensing path and a third condensing path by a first air guide and a second air guide.
