The drying device 40 may include a blowing fan 50 that generates airflow circulating in a flow path formed inside the tub 20 and the drying device 40 and a heat pump 60 that removes moisture contained in the air passing through the drum 30 and heats the air to make high-temperature dry air.


The heat pump 60 is configured to remove moisture from the air flowing along the flow path formed inside the drying device 40 and heat the air to make high-temperature dry air. The heat pump 60 may include a compressor 61, a condenser 62, an evaporator 63, and an expansion valve 64. In addition, the heat pump 60 may include a refrigerant pipe 65 that connects the compressor 61, the condenser 62, the evaporator 63, and the expansion valve 64 to circulate the refrigerant.


The heat pump 60 is configured to remove moisture contained in the air and heat the air through heat exchange with the air while the refrigerant circulates through the condenser 62, the expansion valve 64, and the evaporator 63 by the compressor 61.


The evaporator 63 and the condenser 62 may be disposed in the heat exchange duct 43. The evaporator 63 and the condenser 62 are disposed to be spaced apart from each other by a predetermined distance, and the condenser 62 may be disposed downstream of the evaporator 63 in the circulation direction of airflow.


The evaporator 63 is connected to the inflow duct 42 through a filter assembly 70 (71, 72, 73) disposed inside the filter receiving part 45, and may remove moisture by cooling the humid air discharged from the tub 20.


The condenser 62 is connected to the blowing fan 50 and heats the air by emitting heat to the air discharged to the tub 20. Accordingly, the blowing fan 50 may discharge high-temperature dry air to the tub 20.


The compressor 61 may be disposed in the space provided between the discharge duct 44 and the rear cover 12 of the main body 10.


In the washing machine 1 with a drying function according to an embodiment of the disclosure having the above structure, when the blowing fan 50 operates, the air inside the drum 30 forms an airflow, passes through the inflow duct 42, the filter assembly 70, the heat exchange duct 43, and the discharge duct 44, and then again flows into the drum 30.


At this time, the heat pump 60 operates to remove moisture from the air discharged from the drum 30 and increases the temperature of the air. In other words, moisture in the air is removed by the evaporator 63 of the heat pump 60, and the temperature of the air is increased by the condenser 62. The high-temperature dry air is supplied to the drum 30 by the blowing fan 50 to dry the laundry inside the drum 30.

However, the number of holder members 100 is not limited thereto, and the number of holder members 100 may be at least one or more.


Referring to FIG. 4, the housing 41 may include first to fourth side walls 41a, 41b, 41c, and 41d surrounding components disposed inside the housing 41.


The plurality of holder members 100-1, 100-2, and 100-3 may be arranged to be distributed as widely as possible on the drying device 40 in order to stably move the drying device 40.


For example, the first to third holder members 100-1, 100-2, and 100-3 may be disposed on the upper surfaces of the first to third side walls 41a, 41b, and 41c, respectively.


However, the position of the holder member is not limited to this, and the holder member may be disposed in various positions depending on the configuration of the drying device 40. For example, the housing 41 of the drying device 40 may be implemented without the side wall structure. In this case, the first to third holder members 100-1, 100-2, and 100-3 may be formed to protrude from the bottom surface of the housing 41 or from the components disposed inside the drying device 40.


On the other hand, the holder members 100-1, 100-2, and 100-3 may be disposed in the remaining area of the housing 41 excluding the area where the components of the drying device 40 are located.


For example, the holder members 100-1, 100-2, and 100-3 may be disposed in areas other than the area in the housing 41 where the inflow duct 42, the filter receiving part 45, the heat exchange duct 43 where the condenser 62 and the evaporator 63 are accommodated, the discharge duct 44, and the compressor 61 are disposed.


On the other hand, the compressor 61 may be disposed closer to the third side wall 41c than the first side wall 41a, and the second holder member 100-2 may be disposed between the compressor 61 and the discharge duct 44.
