The invention relates to a water treatment device comprising a metallic sleeve inside which at least one metallic sacrificial anode is disposed, said sacrificial anode being connected to the sleeve in an electrically conducting manner. At least one metallic swirling member which generates eddies within the water flow is arranged upstream of a sacrificial anode in the sleeve, particularly in order to cause the sacrificial anode to be cleaned by means of the turbulent water flow.

The invention claimed is: 1. A water treatment unit comprising: a metallic casing having proximal and distal ends; a metallic reacting anode arranged in the metallic casing and electrically conductively connected to the metallic casing; and a turbulence body arranged within the metallic casing between the proximal end of the metallic casing and the metallic reacting anode, such that in use the turbulence body cleanses the metallic reacting anode by creating turbulent water flow; wherein, the turbulence body is formed by two perforated plates which are arranged perpendicular to a direction of flow at a distance to each other, between which there is at least one perforated plate, and wherein the two perpendicular plates have a cross-section approximately corresponding to an internal cross-section of the metallic casing. 2. The water treatment unit of claim 1 further comprising an insulating element separating the turbulence body from direct electrical contact with the metallic reacting anode. 3. The water treatment unit of claim 1 further comprising a turbulence body arranged within the metallic casing between the distal end of the metallic casing and the metallic reacting anode. 4. The water treatment unit of claim 3 wherein the turbulence body between the proximal end of the metallic casing and the metallic reacting anode is oriented to have a 90 degree axial offset compared to the turbulence body arranged between the distal end of the metallic casing and the metallic reacting anode. 5. The water treatment unit of claim 1 further comprising a spacer between the turbulence body and the metallic reacting anode, which creates an offset between the turbulence body and the metallic reacting anode. 6. The water treatment unit of claim 1 further comprising a securing element that fixes the turbulence body in its position. 7. The water treatment unit of claim 1 wherein the turbulence body has at least one element through which water can flow through channels and/or holes. 8. The water treatment unit of claim 1 wherein the turbulence body comprises two or more perforated plates that are oriented differently to each other. 9. The water treatment unit of claim 8 wherein the perforated plates are attached to each other with a connector. 10. The water treatment unit of claim 1 wherein the turbulence body comprises a perforated plate with holes wound spirally in the direction of intended fluid flow. 11. The water treatment unit of claim 1 wherein the turbulence body comprises a perforated plate, wherein the perforations have various cross-section shapes and various cross-section sizes. 12. The water treatment unit of claim 1 wherein the turbulence body comprises a perforated plate, wherein the perforations have various cross-section shapes. 13. The water treatment unit of claim 1 wherein the turbulence body comprises a perforated plate, wherein the perforations have various cross-section sizes. 14. The water treatment unit of claim 1, wherein the two perpendicular plates are arranged such that the perforations of one plate are offset in relation to the perforations of the other plate in the flow direction. 15. The water treatment unit of claim 1, further comprising a second perforated plate arranged between the two perpendicular plates, wherein the second perforated plate converges to the at least one perforated plate adjacent to a face of one of the two perpendicular plates.
