Abstract

A laundry drying machine includes: a cabinet, a drum rotatably disposed in the cabinet and configured to accommodate a target object, and an electric field generator spaced apart from the drum and configured to, based on power being applied to the electric field generator, generate an electric field. The electric field generator includes an anode electrode spaced apart from the drum, fixed to the cabinet, and configured to apply the electric field to the target object, a power supply unit configured to supply the power to the anode electrode, and a matcher configured to match a source impedance of the power and an impedance of a load side. The drum is configured to rotate at an agitating rotation speed in a state in which the power supplied to the anode electrode is stopped, the agitating rotation speed being (i) greater than 0 rpm and (ii) less than 50 rpm.
