Abstract: A warning signal included in a wireless signal received, and the warning signal is displayed in the form of a warning information message. The warning information displaying method includes receiving a wireless signal through one channel among channels including a warning broadcasting channel, changing the current channel to the warning broadcasting channel when the current channel is not the warning broadcasting channel at predetermined intervals, receiving the wireless signal through the warning broadcasting channel, reading warning information corresponding to a warning signal if the wireless signal includes the warning signal, and visibly or audibly outputting the warning information.

Abstract: The present invention discloses a dryer with safety function which can interrupt a drying operation of the dryer in clogging of an exhaust duct. The dry with safety function includes a judgment means for judging clogging of the exhaust duct, and a display means interworking with the judgment means, for displaying the clogging state of the exhaust duct in clogging of the exhaust duct. The user can be rapidly informed of the clogging state of the exhaust duct.

Abstract: A clogging detecting apparatus for a dryer is provided that can check a clogging state of an air passage according to an off time of a drying operation. The clogging detecting apparatus may include a heater for heating the air of the air passage, a temperature control unit for turning on/off a power supply from a power unit to the heater according to a temperature of the air passage or a temperature of the heater, and a judgment unit for judging the clogging state of the air passage according to an on/off time of the temperature control unit. The clogging detecting apparatus may precisely judge the clogging state of the air passage according to a quantity of laundry dried in the dryer regardless of external factors such as a variation of an external common power.

Abstract: The present invention discloses a clogging detecting apparatus for a dryer which can check and display a clogging degree of an air passage. The clogging detecting apparatus for the dryer includes a judgment unit for judging the clogging degree of the air passage, a storing unit for storing the clogging degree of the air passage, and a display unit for displaying the clogging degree to the user. The clogging detecting apparatus for the dryer does not only notify clogging of the air passage but also provides information on the clogging degree, so that the user can precisely check the state of the air passage.
