Since the amount of moisture that can be condensed by the condensing unit 2 per unit time (hereinafter, referred to as a maximum condensing amount) is limited, when the humidity of the gas exhausted from the drum 4 of the washing machine is too high, the moisture that exceeds the maximum condensing amount of the condensing unit 2 without being condensed is re-introduced into the drum 4 through the drying duct 11. Therefore, the first preset humidity may be set according to the maximum condensing amount of the condensing device 2, and the first preset humidity may be configured to: when the humidity of the gas introduced into the condensing flow passage 21 exceeds a first preset humidity, it represents that the amount of moisture introduced into the condensing flow passage 21 per unit time exceeds the maximum condensing amount. Accordingly, the exhaust valve 31 may be configured such that when the humidity sensor detects that the humidity in the condensation flow passage 21 exceeds the first preset humidity, the exhaust valve 31 opens the exhaust port 22 to enable the condensation flow passage 21 to communicate with the outside through the exhaust port 22, thereby exhausting a portion of the moisture in the condensation flow passage 21 out of the drying system, and when the humidity sensor detects that the humidity in the condensation flow passage 21 is lower than the first preset humidity, the exhaust valve 31 closes the exhaust port 22 to cut off the communication of the condensation flow passage 21 with the outside, at this time, since the amount of the moisture entering the condensation flow passage 21 per unit time does not exceed the maximum condensation amount, the moisture in the condensation flow passage 21 can be changed into condensed water to be exhausted without exhausting the moisture through the exhaust port 22.
