<P>PROBLEM TO BE SOLVED: To provide a cloth drier capable of executing highly precise filter clogging detection even though the input voltage to a heater changes. <P>SOLUTION: The cloth drier has a motor 5 for driving a rotary drum 1, a blowing fan 16 blowing circulation air into a water receiving tank 3, a PTC heater 23 arranged in a circulation blowing path, a filter 19 for recovering lint, an intake air thermistor 60 for detecting the temperature of the circulation air, a current detector 24 for detecting the current of the PTC heater 23, an input voltage detector 28 for detecting input voltage of the same, and a controller 26 and is characterized in that the controller 26 determines clogging of the filter 19 by the respective detected values of the intake air thermistor 60, the current detector 24, and the input voltage detector 28 and the highly precise clogging detection of the filter 19 can be executed even though the input voltage to the PTC heater 23 changes. <P>COPYRIGHT: (C)2011,JPO&INPIT |
