here as a result of the advantageous separation or division of the liquid from the drying air a virtually closed liquid circuit is generated such that no retroactive replenishment or if appropriate only very infrequent replenishment of the liquid in the primary circuit 1 is necessary this improves the operation and reduces the outlay for maintenance and servicing during operation furthermore a regeneration or concentration of the hygroscopic liquid after the absorption of water from the moist drying air is advantageous a heater 7 or a heating element heating bar 16 is preferably provided the heating bar 16 is arranged in the reservoir 17 of the structural unit 5 in this way the thinned liquid 4 can be regenerated or concentrated again for later subsequent drying it is basically possible in a household appliance according to the preamble of claim 1 for the inlet water to be used for cooling the hygroscopic liquid 4 and or the reservoir 17 in general a fluid distributing unit a so called diverter may be provided for the distribution of service water for at least two or preferably three outlets or exits said fluid distributing unit having a directing element or switch which rotates about an axis of rotation for example as per document de 10 2004 040 423 here in the washing sump circuit of the machine the third outlet may be used for energy management the two other outlets have hitherto preferably been used for the two spray arms and the third outlet may inter alia supply water or washing liquid to a consumer and or to a latent heat accumulator or heat exchanger or the like or incorporate these into an advantageous energy management system entrances 18 and or exits 19 of.
