Embodiment Construction

[0021] FIG. 1 shows a dishwasher in outline block diagram form with a washing chamber 1 in which items to be washed (not shown) can be placed in cutlery baskets 3 , 5 . In the washing chamber 1 , for example, two spray arms 7 , 9 at different spray heights are provided as spray devices by means of which rinse liquid is applied to the items to be washed. A pump body 11 with a circulation pump 13 is arranged at the bottom of the washing chamber, fluidly connected to the spray arms 7,9 by feed lines 14,15. Downstream of the circulation pump 13 is a heating element 12, or continuous flow heater, which may also be designated as a water heater. The pump body 11 is also linked to the clean water feed line 16 connected with the municipal tap water network and the drain line 17 through a coupling head, wherein a drain pump 18 is provided to extract the rinse liquid from the rinse chamber 1 .

[0022] In the upper region of the rinsing chamber 1 there is an outlet 19 which is connected...

Abstract

The invention relates to a rinsing method for a water-bearing domestic appliance, especially for a dishwasher, which especially comprises a drying unit (22) containing a drying agent that can be reversibly dehydrated, rinsing liquid being heated to a first temperature (TR1) in at least one cycle step (R) of a first rinse cycle in a first operating mode (I). The rinsing method comprises the following steps: detection of scale formation in the water-bearing domestic appliance; comparison with a nominal value for scale formation; and carrying out a rinse cycle in a second operating mode (II) while the rinse liquid is heated to a second temperature (TR2) which is higher than the first temperature (TR1), when the nominal value is exceeded.

Description

technical field [0001] The invention relates to a rinsing method for a water-carrying domestic appliance, in particular a dishwasher, according to the preamble of claim 1 . Background technique [0002] A method for rinsing a dishwasher is known from DE 10 2005 004 089 A1, wherein in the rinsing step, in a heating phase, a certain amount of rinsing liquid provided in the washing chamber is heated to the washing temperature. An adsorption column with a reversible dehydration type material is provided as a drying unit, which absorbs a certain amount of moisture in the air to be dried in a drying step, and stores the water. In the subsequent rinse cycle, followed by the regeneration process or desorption in the washing step, the air flow drawn from the washing chamber and passed through the desiccant is heated by means of an air heater. Under the action of hot air flow, a certain amount of moisture stored in the desiccant is released in the form of hot steam and returned to th...
