Abstract
A device for degerminating water passing through a sanitary appliance includes a housing through which water can flow, a water outlet and a UV lamp located therein that radiates water flowing through the housing and a filtering device provided in the housing in order to destroy the micro-organisms in the water and/or the filtering device. The energy supply circuit of the UV-lamp is controlled by an electronic control unit , which also controls a valve driver circuit for a magnetic valve located in a fresh water feed pipe. The electronic control unit activates the energy supply circuit when it receives a signal for switching on the UV-lamp. The valve driver circuit is activated after a time delay, ensuring that when the magnetic valve opens letting water flow through the housing to the outlet of the appliance, the UV-lamp has reached its full radiation capacity.
