  • Patent number: 11926955
    Abstract: A laundry dryer performs a method for drying laundry with steam or hot air and notifying a user of water shortage. The laundry dryer includes a cabinet, a drum, a steam unit, a storage tank, a supply pump, and a steam controller. The steam controller operates the steam unit upon receiving a steam supply command to supply steam to the drum. When a water level of water stored in at least one of the steam unit or the storage tank is equal to or less than a predetermined water level, the steam controller provides a water shortage notification message for user recognition. The laundry dryer provides the water shortage notification message when a minimum amount of residual water is stored in the storage tank. The number of times to refill the storage tank can be minimized, resulting in an increase in user convenience.
