Abstract

The invention relates to a water-operated household appliance, in particular a dishwasher, having a hydraulic circuit in which washing fluid can be circulated by means of a fluid pump (13). According to the invention, at least one UV irradiation element (23) is arranged for UV irradiation of the washing fluid within the fluid pump (13).

Description

technical field [0001] The present invention relates to a domestic appliance, in particular a dishwasher, for running on water as claimed in the preamble of claim 1 , and to a domestic appliance for running on water as claimed in claim 12 . Appliance fluid pump. Background technique [0002] It is known that when sterilizing a fluid by means of UV irradiation, the fluid does not introduce additional substances, as can be the case with chemical methods such as chlorine treatment or ozone treatment. Thus, in the purification of drinking water, the food or beverage industry or the sanitation of swimming pools, this UV irradiation disinfection is achieved in different embodiment variants. [0003] For example, WO 2007 / 021137 A1 discloses a dishwasher, in the hydraulic circuit of which washing fluid is circulated and sterilized by means of UV irradiation elements. In this solution, the illuminating element is fixed to the inner wall of the washing compartment. Alternatively, t...
