Samsung patents dryer system that recycles heat and moisture
Samsung describes a clothes dryer that uses a desiccant bed to absorb moisture from the air while it dries your clothes. The system then recycles that heat back into the incoming air to improve efficiency.
In the filing’s own words
A dryer includes an exhaust air chamber, an intake air chamber, and a heater configured to heat supply air expelled from a supply air port and expel the heated supply air. The dryer also includes a drum configured to receive the heated supply air expelled from the heater and expel the heated supply air as return air. The dryer further includes a desiccant bed configured to adsorb moisture from the return air and release heat into the return air during a constant rate period of a drying process of the dryer and release adsorbed moisture into the return air during a falling rate period of the drying process of the dryer. The exhaust air chamber is configured to receive the return air from a return air port, transfer heat from the return air into the intake air chamber, and expel the return air from an exhaust port.
What exactly they claim (claim 1)
1. A dryer comprising: an exhaust air chamber; an intake air chamber configured to receive supply air from an intake port, transfer heat from the exhaust air chamber into the supply air, and expel the supply air from a supply air port; a heater configured to heat the supply air expelled from the supply air port and expel the heated supply air; a drum configured to receive the heated supply air expelled from the heater and expel the heated supply air as return air; and a desiccant bed configured to adsorb moisture from the return air and release heat into the return air during a constant rate period of a drying process of the dryer and release adsorbed moisture into the return air during a falling rate period of the drying process of the dryer; wherein the exhaust air chamber is configured to receive the return air from a return air port, transfer heat from the return air into the intake air chamber, and expel the return air from an exhaust port.
