Thermoelectric hair dryer

Abstract

The present disclosure concerns a hair dryer apparatus capable of low power consumption which makes use of a thermoelectric cooling and heating module. The hair dryer includes a motor driven fan which forces ambient air across each opposite face of the thermoelectric module simultaneously and at a high velocity. The thermoelectric module behaves as a heat pump by absorbing heat through a first heat sink in contact with one side of the module, pumping the heat through the module with a low voltage DC electric current, and rejecting the heat through a second heat sink in contact with the second side of the module. Additional Joules heat, created by the power input to the module, is also rejected to ambient through the second heat sink. Air passed over the first heat sink can be mixed with the air passed over the second heat sink by a damper at the air discharge, thereby enabling accurate temperature settings without the use of electronic controls.
