A method for detecting a degree of blockage of an exhaust duct includes detecting the temperature of air in an intake and exhaust system, calculating a rate of change of the detected temperature, and determining a degree of blockage of the exhaust duct based on the detected temperature and the rate of change of the detected temperature.

Clothing dryer and blockage detection method thereof

A clothing dryer and a control method thereof that adjusts a heater capacity based on a humidity change amount (a drying rate) in a second half of a drying period to reduce power consumption without increase of drying time. The clothing dryer includes a drum to receive clothing, first and second hot air heaters, having different capacities, to supply hot air into the drum, a humidity sensor to sense internal humidity of the drum, and a controller to calculate a humidity change amount in the drum, to compare the calculated humidity change amount with a predetermined change amount, and to control only one having the relatively small capacity selected from the first and second hot air heaters to be operated when the humidity change amount is greater than the predetermined change amount.

Clothing dryer and control method thereof

A clothing dryer capable of effectively drying a small amount of substance, and a control method thereof by changing an algorithm of a sensor-dry course, which is configured to control an operation rate, a degree of drying or a temperature of drying, to be adapted to the small load of substance in a case where the substance to be dried has a small load when compared to the entire volume of the clothing dryer, so that the drying efficiency is enhanced regardless of the load of the substance, and a separate option button is provided for a sensor-dry course, so that a small load of substance is dried adaptively to the material characteristic of the substance for a respective dry course, thereby enhancing the drying efficiency.

A dryer and a control method thereof, in which load of an object to be dried is detected using a sensor which has less risk of contamination and an anticipated drying time based on the detected load is accurately determined and displayed. The dryer includes a rotatable drum to accommodate the object, a front support installed at an entrance of the drum to support the drum, a rear support installed at an opposite side of the entrance of the drum to support the drum, an exhaust hole formed in the front support, through which interior air of the drum is discharged, and a humidity sensor installed to the front support at a position adjacent to the exhaust hole, the humidity sensor being located upstream of the exhaust hole in a rotating direction of the drum to detect humidity of the air to be introduced into the exhaust hole.
