A bathroom management apparatus may include a case having an air suction port formed in an upper portion of a front surface thereof, a first air discharge port formed in a lower portion of the front surface thereof, and a second air discharge port formed in a lower surface thereof. A suction vane opens or closes the air suction port, and first and second discharge vanes opens or closes the first and second air discharge ports, respectively. A duct is provided in the case to connect the air suction port, the first air discharge port and the second air discharge port to one another. A blowing fan is provided in the duct to suck air through the air suction port and blow the air to the first air discharge port and the second air discharge port. A heater heats the air in the duct.

Air blower apparatus

A method of controlling a dryer includes rotating a drum within the dryer in a first direction, detecting at least one of temperature or relative humidity of air discharged from the drum while the drum is rotating in the first direction, and sensing occurrence of entanglement inside the drum by comparing a variation rate of at least one of the detected temperature or the detected relative humidity with a corresponding reference value. The method also includes, based on sensing that the entanglement has occurred, reversing a rotation direction of the drum by rotating the drum in a second direction that is opposite the first direction, and further, based on reversing the rotation direction of the drum upon sensing that the entanglement has occurred, maintaining the second direction of rotation of the drum for a preset time.

Dryer and control method thereof

A clothes treating apparatus that includes a heat pump cycle and a dehumidifying device is provided herein. The clothes treating apparatus may include a case and a drum installed within the case and configured to accommodate an item for drying. A circulation duct may be provided to form an air circulation flow channel that allows air to circulate through the drum. The heat pump cycle may include an evaporator and a condenser disposed to be spaced apart from one another within the circulation duct, the heat pump cycle being configured to absorb heat of air released from the drum through the evaporator and transmit the absorbed heat to air introduced to the drum through the condenser, by using a working fluid that circulates by way of the evaporator and the condenser. Moreover, the dehumidification device may be provided to dehumidify air passing through the evaporator in the circulation duct.
