Abstract
A home laundry dryer in which both the fresh air entering a laundry drum and the air exhausted from the drum pass through a thermal recovery unit in the dryer. The unit has a high temperature passage through which the exhaust air flows and a low temperature passage through which the entering air flows. Heat from the exhausted air is transferred by means of heat pipes from the high temperature passage to the entering air in the low temperature passage. This heat transfer lowers the energy required to raise the entering air to a selected drying temperature. The dryer, including the thermal recovery unit, fits in a housing of substantially standard size for home dryers.
