Abstract: The present invention relates to a blower dryer appliance typically used for drying and styling hair. When electrically activated, these appliances virtually always route electrical power to the fan or blower motor prior to or simultaneously with the heating element(s). Semiconducting switching devices used for regulating, controlling and/or switching electrical power generate waste heat that must be dissipated. Typically, heat is conducted and/or channeled away from the semiconducting switching device through a heat sink which is thermodynamic-mechanically coupled to the device. The greater the coverage area of the heat sink, the more waste heat can be dissipated depending on the ability of the heat sink to make contact with cooler, ambient air. This adds costs to the dryer/blower for engineering the heat sink, cost of the sink itself, and necessary design changes in the dryer/blower for accommodating the sink.

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.
