Water system for a vehicle and method for reducing germs in a water system

摘要

A water system for a vehicle is provided. The water system comprises at least one water supply source, at least one water-conducting device, at least one closing valve and at least one germ reduction connection. The germ reduction connection and the water supply source are connected to the water-conducting device. The germ reduction connection is designed to introduce a germ-reducing fluid into the water-conducting device. The closing valve is arranged between the water supply source and the germ reduction connection and is designed to be fully closed thus preventing the ingress of germ-reducing fluid into the water supply source. By means of such a water system it is possible to carry out sterilization or disinfection very easily and quickly without this requiring any major maintenance work.

主权项

1. A water system for a vehicle having a water flow path, comprising:
at least one fuel cell having an outlet; at least one water-conducting device connected to the at least one fuel cell at the outlet; a first closing valve positioned at the outlet of the at least one fuel cell such that the outlet and the first closing valve are between the at least one fuel cell and the at least one water conducting device along the water flow path; a water supply tank coupled to the at least one water-conducting device downstream from the at least one fuel cell; at least one vent valve for venting the at least one water-conducting device during a germ reduction; a second closing valve positioned at the water supply tank between the water supply tank and the at least one water conducting device along the water flow path; and at least one germ reduction connection connected to the water conducting device between the first closing valve and the second closing valve to introduce a germ-reducing fluid into the at least one water-conducting device for germ reduction of the water-conducting device, wherein the first closing valve and second closing valve are fully closeable to prevent any ingress of germ-reducing fluid into the at least one fuel cell and the water supply tank such that only the at least one water conducting device receives the germ-reducing fluid.
