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.

Abstract: The present disclosure relates to a circulation pump driving apparatus and a laundry treatment machine. A circulation pump driving apparatus and a laundry treatment machine according to an embodiment of the present disclosure includes an inverter converting a DC voltage from a converter into an alternating current (AC) voltage by a switching operation and outputting the converted AC voltage to a circulation pump motor, and a controller to control the circulation pump motor to operate in at least two modes among a first mode in which a speed of the circulation pump motor is constant, a second mode in which the speed of the circulation pump motor repeatedly rises and falls, and a third mode in which the speed of the circulation pump motor rises at a first rising slope and a second rising slope and then remains constant. Accordingly, it is possible to improve washing power due to circulation pumping during washing.

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: The present disclosure relates to a laundry treatment machine. A laundry treatment machine according to an embodiment of the present disclosure includes: an inverter converting a direct current (DC) voltage from a converter into an alternating current (AC) voltage based on a switching operation and outputting the converted AC voltage to a circulation pump motor; and a controller to control a speed of the circulation pump motor to be increased before a time point at which a speed of a washing tub motor increases. Accordingly, the washing tub motor and the circulation pump motor can be operated in synchronization with each other. As a result, it is possible to improve washing power based on circulation pumping during washing.
