METHOD OF CONTROLLING TEMPERATURE OF COLD/WARM FORHEAD MASSAGE DEVICE

摘要

The present invention relates to a method of controlling temperature of a cold/heat forehead massage device. In the temperature control method, a control unit (220) supplies first current to a thermoelectric element (230). The control unit (220) measures time for which the first current is supplied, and determines whether the measured time exceeds first time. If measured time exceeds the first time, the control unit supplies second current to the thermoelectric element. The control unit measures time for which the second current is supplied, and determines whether the measured time exceeds second time. If the measured time exceeds the second time, the control unit supplies third current to the thermoelectric element. The control unit measures time for which the third current is supplied, determines whether the measured time exceeds a third time, and terminates temperature control if the measured time exceeds the third time.
