When the frost layer on the surface of the first evaporator 30 is completely melted, the high-temperature gaseous refrigerant flows through the heat-conducting member 70 between the first evaporator 30 and the second evaporator 40, and the frost layer on the surface of the heat-conducting member 70 is also melted. Meanwhile, the heat conduction member 70 transfers heat to the second evaporator 40, and the surface of the second evaporator 40 is heated to start defrosting.
