Abstract: A humidifier may include a water tank that stores water, a heating device configured to be supplied with water from the water tank and heat the water, a humidifying device that is connected with the heating device and produces humidified air using water supplied from the heating device, a first connection tube that connects the heating device and the humidifying device, a second connection tube that connects the heating device and the humidifying device at a position different from the first connection tube, and a pump disposed at a side of the second connection tube that pumps water stored in the humidifying device to the heating device.

Abstract: A humidifier may include a tank that stores water; a first humidifying water tank that is disposed at a lower side of the water tank and heats water supplied from the water tank using a heater; a second humidifying water tank that is disposed at the lower side of the water tank and generates humidified air using water supplied from the first humidifying water tank via a vibrator; a first connection pipe that connects the first humidifying water tank and the second humidifying water tank; a first valve that opens and closes a flow path connecting the water tank and the first humidifying water tank; a second valve that opens and closes the first connection pipe; and a first temperature sensor that detects a temperature of water inside of the first humidifying water tank. The second valve may open the first connection pipe, when the temperature of water detected by the first temperature sensor is equal to or higher than a first predetermined temperature.

Abstract: A humidifier may include a housing; a water heater tank disposed within the housing, a heater being located at a bottom of the water heater tank; a humidification water tank that is disposed within the housing and connected to the water heater tank to be supplied with water from the water heater tank; a vaporization unit that vaporizes water contained in the humidification water tank; and a drainage pipe that is connected to the water heater tank and drains the water contained in the water heater tank.

Abstract: 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.

Abstract: A blower includes a housing through which air is introduced, a plurality of discharge ports disposed above the housing, each having a discharge port, and facing each other, a blowing space formed to be spaced at least partly between the plurality of discharge departments facing each other and open at least front and rear, a ground disposed on a downstream side of the blowing fan, spaced downward from the plurality of discharge departments, and connected to the housing, and a supporter extending upward from the ground to support the plurality of discharge departments. Accordingly, it is possible to improve blowing performance of the blower by reducing the occurrence of vortex through a pressure buffer zone formed by vertical separation of the ground and the discharge department, and structural stability of the blower can be improved by supporting the discharge department by the supporter and ground disposed inside the housing.

Abstract: A blower includes a lower case provided with an inlet; a first tower that extends upward from the lower case and is formed with a first outlet; a second tower that extends upward from the lower case and is provided with a second outlet; a fan that is rotatably disposed on the lower case; a first air flow converter that is disposed at the first tower; and a second air flow converter that is disposed at the second tower, each of the first air flow converter and the second air flow converter including: a guide board that is disposed inside the first tower or the second tower or protrudes through a first wall or a second wall; an upper gear that rotates in engagement with an upper portion of the guide board; a lower gear that rotates in engagement with a lower portion of the guide board; a shaft that is connected to each of the upper gear and the lower gear to rotate together; and a motor that is connected to one of the upper gear and the lower gear to provide a driving force.
