Abstract: A laundry drying machine includes: a cabinet, a drum rotatably disposed in the cabinet and configured to accommodate a target object, 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, and an exhaust duct configured to discharge air inside the drum. The electric field generator includes: (i) an anode electrode spaced apart from the drum, fixed to the cabinet, and configured to apply the electric field to the target object, (ii) a power supply unit configured to supply the power to the anode electrode, and (iii) a matcher configured to match a source impedance of the power and an impedance of a load side. The drum is configured to, based on a reflectivity of the electric field exceeding a predetermined ratio, reduce a rotation speed.

Abstract: A laundry drying machine includes: a cabinet, a drum disposed inside the cabinet and configured to accommodate a target object, a driving unit configured to rotate the drum, and an electric field generator spaced apart from the drum and configured to generate an electric field inside the drum. The drum includes: a drum body having a cylindrical shape and accommodating the target object, a ground electrode that is in contact with an outer circumferential surface of the drum body, and a support roller that is in contact with the outer circumferential surface and that is configured to, based on the drum body rotating, support the drum body in a direction of the ground electrode, and a shortest distance between a central axis of the support roller and the ground electrode is less than a sum of a diameter of the drum body and a radius of the support roller.

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.
