Abstract: A hair dryer stand for setting an operating blow-dryer on a countertop without burning the countertop or material on the countertop. The hair dryer stand comprises at least one base, at least one side wall having a top and a bottom where the bottom is attached to the base, at least one vent, and an opening wherein the opening profile is defined by the top of the side wall and can receive the intake side of a blow-dryer that is turned on. In use, the blow-dryer is supported in the opening and suspended above the countertop. Air is allowed to flow into the intake side of the blow-dryer, over the heating coils inside blow-dryer and prevents the blow-dryer from overheating. Also, the exhaust side of the blow-dryer is directed upward, away from the countertop so the countertop or material on countertop will not burn.

Abstract: The present invention uses electric current to either chill or warm air ambient air. The Portable Thermoelectric Cooling and Heating Device is composed of an array of thermoelectric units, a driving fan, a cold sink, a hot sink, air baffles and a cooling fan. The thermoelectric units are arranged in contact with the cold sink (cold side) and hot sink (hot side). Applying a current causes a temperature difference to develop between each side. The driving fan creates a pressure gradient is to pull air through the center of the cold sink. The cooling fan pulls air through an arrangement of baffles connected to the hot sink to help dissipate heat. The result is chilled or hot air, depending on the direction of the current. The invention allows for several improvements over current heating and air-conditioning systems: a simplified design without moving parts, elimination of the need for FREON, improved versatility and others.
