Patent ID: 8307839

Claim:
A cleaning appliance for cleaning washware, the cleaning appliance being designed to subject the washware to the action of at least one cleaning fluid in at least one operating mode, the cleaning appliance comprising: at least one cleaning chamber; a suction-removal apparatus for removing damp air from the at least one cleaning chamber by suction; at least one heat recovery device, the heat recovery device configured to draw heat from the damp air by a first cooling fluid; and a cooling-fluid line connected to the at least one cleaning chamber having at least one cooling path and at least one heat accumulator path branching off from said at least one cooling path, said at least one heat accumulator path including at least one latent heat accumulator; wherein the first cooling fluid flows to the cleaning chamber and/or into a fluid tank via the cooling path in said at least one operating state after said cooling fluid has flowed through the heat recovery device, wherein the first cooling fluid circulates through the cooling fluid line to the latent heat accumulator via the heat accumulator path in at least one standby mode, wherein the latent heat accumulator is a multi-stage latent heat accumulator with at least two transition temperatures, wherein the latent heat accumulator has at least one transition temperature in the range between 30° C. and 90° C., and wherein the heat recovery device has at least one thermoelectric heat pump and/or at least one thermomechanical heat pump, wherein the cooling fluid line has a first section, the first section branching at a first point of intersection into a second section, the second section forking at a second point of intersection into a third section and a fourth section, and wherein the latent heat accumulator is located in the fourth section of the cooling fluid line, the fourth section being parallel to the third section of the cooling fluid line, the third section being part of the cooling path.
