HUMIDIFIER

A humidifier may include a first humidifying water tank in which a first chamber in which water is heated is formed; a second humidifying water tank that is connected to the first humidifying water tank and having a second chamber in which humidified air is generated using water supplied from the first humidifying water tank via a vibrator; a fan that is disposed below the second humidifying water tank and forms an air flow; and a connection pipe that directs water stored in the first humidifying water tank to the second humidifying water tank. An exhaust hole through which humidified air generated in the second chamber is discharged to the outside and an air supply hole through which air blown by the fan is supplied to the second chamber may be formed in the second humidifying water tank. The second humidifying water tank may further include a lower extension wall that is disposed between the exhaust hole and the air supply hole and guides air flowing into the second chamber through the air supply hole to a lower portion of the second chamber.
