Jet former, in particular for a sanitary shower head, comprising a rotor blade that is configured and designed to divide a flow of water into parts and partial flows
A jet former, including an impeller wheel rotatably mounted about an axis of rotation, having a blade arrangement, a control device, and at least one movably mounted nozzle. The control device is arranged and constructed to convert a rotation of the axis of rotation into a movement of the at least one nozzle. At least one blade of the blade arrangement is arranged and formed to divide the water flow directed towards the at least one blade in a direction of flow into at least a first partial flow and a further partial flow, to deviate the first partial flow in a first partial flow direction, and to deviate the other partial flow in a further partial flow direction. The direction of flow, the first partial flow direction and the further partial flow direction in each case differ from each other.
1. A shower head comprising:
a shower head housing; and
a jet former accommodated in the shower head housing,
the jet former comprising:
an impeller wheel rotatably mounted about a shaft that forms an axis of rotation, the impeller wheel having a blade arrangement,
wherein at least one blade of the blade arrangement is arranged and configured to:
divide a water flow directed towards the at least one blade in a direction of flow into at least a first partial flow and a further partial flow;
deviate the first partial flow in a first partial flow direction; and
deviate the further partial flow in a further partial flow direction, wherein the direction of flow, the first partial flow direction, and the further partial flow direction differ from one another,
wherein a front face of the shower head housing, through which the water flow exits the shower head, remains stationary with respect to the impeller wheel, such that the impeller wheel rotates relative to the front face of the shower head housing.
2. The shower head according to claim 1 , wherein the at least one blade comprises:
a blade bottom surface; and
a flow divider,
wherein the flow divider is arranged and formed to divide the water flow directed towards the at least one blade in the direction of flow into the first partial flow and the further partial flow.
3. The shower head according to claim 2 , wherein a cross section of the blade bottom surface in a cross sectional plane through the blade bottom surface in parallel with the axis of rotation is not curved.
4. The shower head according to claim 2 , wherein a cross section of the flow divider, in a cross sectional plane through the flow divider perpendicular with the axis of rotation, is curved.
5. The shower head according to claim 1 , wherein the at least one blade of the blade arrangement is arranged and formed to;
deviate the first partial flow by a first deflection angle in a range of 45 to 180° in the first partial flow direction; or
deviate the further partial flow by a further deflection angle in a range of 45 to 180° in the further partial flow direction; or
both.
6. The shower head according to claim 1 , wherein the housing includes at least one intake nozzle, wherein the at least one intake nozzle is arranged and adapted for the water flow to be directed towards the impeller wheel in the direction of flow.
7. A device comprising the shower head according to claim 1 , wherein the shower head is water-conductively connected to a mixing device to mix water of at least two different temperatures.
8. A shower comprising the shower head according to claim 1 .
