METHOD CONTROLLING HEATER OF DRYER HAVING INDRAWN TUBE BUILT IN HEATER

摘要

A heater control method of a drier with a heater embedded suction pipe is provided to efficiently control the heat relative to the discharge temperature at an outlet. A heater control method of a drier with a heater embedded suction pipe is as follows. It classifies temperature control and time control according to a selected drying temperature range. The temperature control operates one heater among a plurality of heaters in order to perform the temperature control. The time control performs the time control about another heater while control operates one heater among a plurality of heaters. The drying temperature range performing the temperature control is consisting of a low temperature dry step(S30) and an extremity low temperature dry step(S20). The low temperature dry step operates the heater where discharge air temperature is 40°C and makes the heater stop at 47°C. The extremity low temperature dry step operates the heater where discharge air temperature is 33°C and makes the heater stop at 40°C.
