Abstract: The present invention relates to a laundry handling apparatus and a control method therefor. The laundry handling apparatus of the present invention comprises: a cabinet; a tub in which washing water is accommodated; an electric heater for raising the temperature of the washing water of the tub; and an air pump for supplying air under the water surface of the electric heater so as to raise the level of the washing water with which the electric heater comes into contact. Therefore, when the heated washing water is supplied into the tub, the level of the washing water rises so as to prevent the electric heater from being exposed to the water surface, thereby preventing the damage of the electric heater. In addition, since the water level rises by the air, the amount of the washing water used can be reduced.
