  • Publication number: 20250146680
    Abstract: An indoor unit of an air conditioner in which filtered air is blown inside a steam generator via a humidification fan, and humidified air inside the steam generator is discharged to the side of a steam guide, where a sufficient flow may be supplied to the inside of the steam generator, such that the steam and the filtered air may be effectively mixed, thereby enabling the generation of humidified air. Since the humidification fan blows intake air into the steam generator so as to enable humidified air to flow, the humidified air may flow up to a discharge port even when an independent flow channel of the steam guide is long.

  • Patent number: 12215890
    Abstract: An indoor unit for an air conditioner in which the water level of a steam generator is linked with the water level of a supply chamber for supplying water to the steam generator, and a supply floater, which is lowered or raised according to the water level of the supply chamber, opens and closes a supply flow channel for supplying water to the supply chamber. The indoor unit for an air conditioner can control the water supply through the level of water stored in the steam generator.

  • Publication number: 20250035327
    Abstract: The present invention relates to a steam generator comprising: a steam housing which forms the exterior and has a space in which water is stored; a steam heater disposed inside the steam housing and generating heat by means of an applied power; a water pipe disposed on one side of the peripheral surface of the steam housing and having a communication hole through which water is introduced from the outside into the steam housing or water inside the steam housing is discharged to the outside; an air inlet part disposed on the upper surface of the steam housing and having an air inlet through which air is introduced into the steam housing; a steam outlet part disposed on the upper surface of the steam housing apart from the air inlet part by a predetermined distance and having a steam outlet through which steam generated inside the steam housing and the air introduced through the air inlet part are discharged to the outside.
