Abstract

Disclosed is a cleaning device for a washing apparatus arranged in a vehicle, comprising a housing with a chamber which is formed in the housing, is configured to be filled with cleaning fluid and is hydraulically connectable to at least one spray nozzle for the cleaning fluid, and with at least one heatable heating wire protruding at least in sections into the chamber. To obtain high functional reliability even at low temperatures and to permit particularly rapid and reliable deicing, a heat-conducting element is arranged in the chamber to enlarge a heat-transferring convection surface, said heat-conducting element absorbing the heat from the heating wire, and being at least partially, and preferably completely, surrounded by the cleaning fluid.
