A household appliance has a working chamber and at least one latent heat store having a respective storage medium. The storage medium is thermally coupled via a respective associated heat exchanger to a working medium circulating through the working chamber. The working medium moves from the working chamber to a heat sink, from the heat sink to the heat exchanger, from the heat exchanger to a heat source, and from the heat source back to the working chamber. The storage medium forms a substance mixture together with a respective carrier fluid. The substance mixture can be conducted in a respective closed circuit through the associated heat exchanger for an exchange of heat with the working medium, and the substance mixture circulates between the associated heat exchanger and at least one reservoir in the respective closed circuit. The reservoir can be refilled layer-by-layer with the substance mixture conducted through the respective associated heat exchanger.

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.

In a method for operating an adsorption dryer, a process air flow, generated by at least one blower, is routed at least at times through an adsorption apparatus and over a textile goods in care during a textile care process in a 'dry' operating mode to thereby charge a reversibly dehydratable adsorbent of the adsorption apparatus with moisture. A charge state of the adsorbent with water is detected and is displayed at least after the end of the 'drying' textile care process. The absorbent is desorbed at least in part during a subsequent, selected and started textile care process in a &#x201c;refresh&#x201d; operating mode, and the desorbed moisture is routed as a moist process air flow into a receptacle for refreshing textile goods which are stored or hung in a stationary manner.
