DOMESTIC DISHWASHER HAVING A SORPTION DRYING SYSTEM AND ASSOCIATED METHOD FOR CARRYING OUT AN ENERGY-SAVING DISHWASHING PROGRAM

The invention relates to a domestic dishwasher (GS) having a sorption drying system (SY) which comprises: a circulating air channel (UK); a sorption container (SOB) which is fluidically inserted into the circulating air channel (UK) and has a fixed bed (FS) of a grainy or granular sorption material (SM) which can be reversibly dehydrated; an air conveyor unit (LF) which is fluidically inserted into the circulating air channel (UK); and a desorption heating device (HV) for regenerating the sorption material. A control logic (LO) changes the conveyor volume flow (FV) of the dishwasher interior air (PL') which is conveyed by the air conveyor unit (LF) and heated by means of the desorption heating device (HV), and therefore the regeneration temperature (TR) produced in the sorption material (SM) over the through-flow stretch (HS) of the fixed bed (FS) as a specific function of each predetermined regeneration duration (RD, KRD) of the regeneration phase (RG, KRG) of each dishwashing program (GP, EP). In addition to or independently of this, the control logic (LO) specifically sets the conveyor volume flow (FV) of the air conveyor unit (LF) for the regeneration phase (KRG) of at least one energy-saving dishwashing program (EP) in such a way that the sorption material (SM) is brought only to a regeneration temperature (TR) at which an increased minimum residual moisture content (GW) of water of between 5% and 15%, in particular between 10% and 15%, based on the total dry mass of the sorption material (SM), remains in said sorption material.
