Embodiment Construction

[0026] figure 1 is a highly schematic illustration of a dishwasher with a washing compartment 1 in which food-contaminated items (not shown) to be cleaned can be arranged in cutlery baskets 3 , 5 . In the shown washing compartment 1 , two, in particular rotatably mounted, spray arms 7 , 9 arranged on different spray surfaces are exemplarily provided as spray devices, the items to be cleaned Washing fluid can be sprayed by means of the spraying device. A pump sump 11 is arranged below the bottom of the washing compartment, the pump sump 11 having an associated circulation pump 13 fluidly connected to the spray arms 7 , 9 via fluid lines 14 , 15 , 16 . The pump sump 11 is also connected via a connecting branch to a fresh water line 17 connected to the water supply system and a drain line 18 in which a drain pump 19 is arranged to drain dirty washing fluid Pump out from wash compartment 1.

Abstract

The appliance i.e. dishwasher has a hydraulic circuit including a water diverter (21) in which rinsing liquid is circulated. A UV radiation element (23) is arranged such that UV irradiation of the rinsing liquid takes place within the water diverter, where the UV irradiation element and the water diverter form a common component mountable into the household appliance. The water diverter includes an adjustable switching element (22) operated to control partial flow of the rinsing liquid.

Description

technical field [0001] The invention relates to a water-operated domestic appliance, in particular a dishwasher, as described in the preamble of claim 1 , and to a water-operated domestic appliance according to claim 12 A water dispenser, and a fluid pump as claimed in claim 13. Background technique [0002] It is known that when a fluid is sterilized by means of UV irradiation, no additional substances are introduced into the fluid, as would be the case with chemical methods such as chlorine or ozone treatment. In the purification of drinking water, in the food or beverage industry or in the sanitation of swimming pools, such UV radiation disinfection is thus realized in different embodiment variants. [0003] For example, WO 2007 / 021137 A1 discloses a dishwasher in which washing fluid is circulated in a hydraulic circuit and sterilized by means of UV irradiation elements. In this solution, the illuminating element is fixed to the inner wall of the washing compartment. A...
