Structural unit, in particular heating pump, comprising a heatable tube section for a water-conducting domestic appliance, and water-conducting domestic appliance comprising such a structural unit

Abstract

The invention relates to a structural unit (14), in particular a heating pump for a water-conducting domestic appliance (1), in particular a domestic dishwasher, having a heatable tube section (15) through which a liquid can flow during operation and in which one or more mechanical structures (19; 20) are arranged that produce locally different flow speeds of the liquid. The exterior (24) of the tube section (18) is paired with at least two temperature measuring devices (22; 23). A first temperature measuring device (22) is arranged radially outside of a region with a lower flow speed or worseinflow, and a second temperature measuring device (23) is arranged radially outside of a region with a higher flow speed or better inflow.

Description

technical field [0001] The invention relates to a structural unit or a heating device, in particular a heat pump, for a water-conducting household appliance (1), in particular a domestic dishwasher or washing machine, according to claim 1 or 2, with a pipe section, the pipe section It can be passed through and heated by liquid during operation. Background technique [0002] In water-conducting domestic appliances, in particular such liquid heating devices of dishwashers or washing machines, it is problematic to operate with calcium-rich water without taking appropriate measures to soften the water. On the other hand, overdosing of chemicals that reduce water hardness should be avoided as much as possible. [0003] Through incorrect hardness adjustment, using too little cleaning agent, incorrectly using cleaning tablets without softener, using biological cleaning agents, running without salt, not replenishing salt, not recognizing salt amount, regeneration valve hanging or m...
