Abstract: A domestic appliance for drying a damp product by means of a process air stream that is conducted in a process air channel. The appliance has a treatment chamber that includes the damp product. A cooling assembly cools and condenses the process air stream after it flows through the treatment chamber. A first heat exchanger supplies heat from the process air stream to a working fluid. A heating assembly heats the process air stream before it flows through the treatment chamber and a second heat exchanger supplies heat from the working fluid to the process air stream. The working fluid is conducted in a heat pump that has at least two mechanically coupled displacement pistons. The heat pump operates according to a regenerative gas cycle process that includes a Vuilleumier gas cycle process.

Abstract: The domestic appliance is designed to dry a humid product by means of a process air stream that can be conducted in a process air channel, said stream flowing through a treatment chamber comprising the product and a cooling assembly for cooling and condensing the process air stream once the latter has passed through the treatment chamber. The cooling assembly has a first heat exchanger, by means of which heal from the process air stream can be supplied to a working fluid, and a heating assembly connected downstream of the cooling assembly for heating the process air stream before the latter flows through the treatment chamber, said beating assembly having a second heat exchanger, by means of which heat from the working fluid can be supplied to the process air stream. The working fluid is conducted in a heat pump, which operates according to a regenerative gas process.
