Dryer and method for controlling same

A dryer according to one embodiment comprises: a drum; a heat pump; a user interface; a power supply module for controlling power supply to a drum motor connected to the drum and a compressor motor of the heat pump; a duct that accommodates the evaporator and the condenser of the heat pump, heats the air flowing in from the drum, and discharges the air to the drum; a plurality of temperature sensors for sensing a temperature of each of the heat pump, the power module, and the duct; and a control unit for controlling the user interface to determine a management target factor among a plurality of factors causing incomplete drying based on at least one of output data of the plurality of temperature sensors or opening data of the electronic expansion valve provided in the heat pump, and outputting a notification for the management target factor. 根据一个实施例的烘干机包括：滚筒；热泵；用户接口；电源模块，用于控制对连接到滚筒的滚筒电机和热泵的压缩机电机的供电；管道，容纳热泵的蒸发器和冷凝器，对从滚筒流入的空气进行加热，并将空气排出至滚筒；多个温度传感器，用于感测热泵、电源模块和管道中的每一个的温度；以及控制单元，用于控制用户接口基于多个温度传感器的输出数据或热泵中提供的电子膨胀阀
