Abstract

PURPOSE: To perform a high temperature operation and the clogging detection of an air filter by measuring a load current operated by the upper limit value of a control operation, arithmetically processing whether or not it is within a filter clogging allowable load current range in a central control circuit and performing reporting in the case of being below a set load current. CONSTITUTION: An electric type heating element H1 is used at the time of a weak operation and detects the clogging of the air filter. That is, the wind amount/electric characteristics of a ceramic heating element are utilized and the clogging of the air filter is detected. The electric type heating element H2 raises an air temperature inside a drier drum and dries clothes or the like. The electric type heating element H3 gets closer to the upper limit value of a maximum current control operation allowed to a drier as much as possible and performs a high temperature operation. A current detector CT measures the entire current of a load and the current of the electric type heating element H1 for filter clogging detection and a CT signal conversion circuit 5 transmits the signals of the CT to the central control circuit 2. The difference current of the entire current and the current flowing to the heating element H2 is detected, and a state amount for the maximum current operation control and air filter clogging reporting is detected.
