Abstract

The apparatus for the disinfection of aqueous media in a tank wherein the media is exposed to ultraviolet radiation from a tubular watertight UV source, an electronic control unit is attached to the tank for the control of the UV source, the container is provided with a cover that can be tilted open and has a handle and the source is arranged substantially along a middle axis of the apparatus.

Claims

1. Apparatus for the disinfection of aqueous media, in particular for the production of drinking water, comprising a household type container in which an aqueous medium is exposed to ultraviolet radiation, and this radiation is provided by a tubular watertight UV source rigidly mounted to a bottom of said container, said UV source having one of a round or oval cross section and being arranged in said container substantially along an upstanding middle axis of said container (2), an electronic control unit (6) mounted to said container (2) for the control of the UV source (7), said electronic control unit (6) including a connection (10) to a power supply, a circuit closer for the electronic control unit (6) and a timer (16), said electronic control unit (6) being constructed and arranged so that the electronic control unit (6) turns the apparatus (1) off after a certain period of time, said apparatus further including a cover (3) for said container (2) that is constructed and arranged so that said cover can be titled, and said container including a handle (8) which enables said container to be tilted open and said electronic control unit (6) being constructed and arranged so that the electronic control unit (6) turns the apparatus (1) off upon opening of the tiltable cover.

2. Apparatus according to claim 1, characterized in that

said electronic control unit (6) and the UV source (7) are selected for operation with 12 Volt direct current.

3. Apparatus according to claim 1, characterized in that

said electronic control unit (6) is mounted in a housing (5) under said bottom of said container (2).

4. Apparatus according to claim 1, characterized in that

said electronic control unit (6) includes switching circuitry associated with said cover whereby the opening of the container (2) triggers the shutdown of the UV source (7).

5. Apparatus according to claim 2, characterized in that

said apparatus includes a power supply and a solar module (12).

6. Apparatus for the disinfection of aqueous media, in particular for the production of drinking water, comprising a household type container in which an aqueous medium is exposed to ultraviolet radiation, and this radiation is provided by a tubular watertight UV source rigidly mounted to a bottom of said container, said UV source having one of a round or oval cross section and being arranged substantially along an upstanding middle axis of the container (2), an electronic control unit (6) mounted to said container (2) for the control of the UV source (7), said electronic control unit (6) including a connection (10) to a power supply, a circuit closer for the electronic control unit (6) and a timer (16), said electronic control unit (6) being constructed and arranged so that the electronic control unit (6) turns the apparatus (1) off after a certain period of time, said apparatus further including a cover (3) for said container (2), said container including a handle (8) which enables said container to be tilted open and said container (2) being provided with a heating arrangement for heating the aqueous medium.
