DRYER AND A HEATER DRIVING CONTROL METHOD THEREOF FOR VARIOUSLY SETTING DRYING CONDITIONS BY JUDGING A CURRENT STATE OF THE HEATER ACCORDING TO THE HEATER'S PREVIOUS OPERATION

摘要

PURPOSE: A dryer with a heater driving control function is provided to shorten the drying time by judging a heater driving based on the previous operation and to improve drying efficiency by setting various drying patterns according to the previous state of the heater driving. CONSTITUTION: A dryer with a heater(400) and a storage unit(700) comprises a key input unit(100) for inserting a demand order of users; a temperature sensing unit(200) measuring a temperature in an inner tub of the dryer according to driving/stopping the dryer; a microcomputer(300) judging an operation state of the heater by comparing the currently sensed temperature with a sum of the previous temperature value memorized in the storage unit and a predetermined temperature; a load driving unit(600) controlling the heater's driving according to control signals from the microcomputer; and an error display unit(800) showing errors of the heater. The temperature sensing unit measures temperature of the inner tub in real-time when the heater driving stops.
