1. A laundry drying machine comprising:
a cabinet;
a drum that is rotatably disposed in the cabinet and that is configured to accommodate a target object;
an electric field generator that is spaced apart from the drum and that is configured to, based on power being applied to the electric field generator, generate an electric field inside the drum; and
an exhaust duct configured to discharge air inside the drum,
wherein the electric field generator includes:
an anode electrode that is spaced apart from the drum, that is fixed to the cabinet, and that is configured to apply the electric field to the target object accommodated in the drum,
a power supply unit that is configured to supply the power to the anode electrode, and
a matcher that is provided in the cabinet and that is configured to match a source impedance of the power and an impedance of a load side, and

wherein the drum is configured to, based on a reflectivity of the electric field exceeding a predetermined ratio, reduce a rotation speed.
