In this case, a maintenance notification urging the user to perform filter maintenance is performed (S9). On the other hand, if the drainage time is equal to or longer than the second predetermined time (NO in S8), it is determined that clogging has occurred in the lint filter, and the user is informed of the occurrence of clogging, and an error notification for urging filter maintenance is given.

For example, an alarm sound can be sounded, and an error display can be displayed on the notification unit 104 (in this case, the display unit) to notify the occurrence of filter clogging. Further, similarly to the maintenance notification, an error notification may be transmitted to a smartphone or the like owned by the user. In this case, for example, as shown in FIG. 3B, a message notification indicating that filter clogging has occurred can be performed on the application screen.
