DE10361275A1 - Influx nozzle e.g. for swimming pools, has hollow ball body made from two parts and are rotatable relative to each other around axis of rotation with each part having outlet for water jet - Google Patents

Abstract

In an inlet nozzle according to the invention, in particular for swimming pools, a hollow ball body (1) is provided, which consists of at least two parts (2, 3) which are rotatable relative to each other about a rotation axis (D), wherein each part (2, 3) at least one outlet opening (6, 7) for a water jet (Fig. 1).

Description

The The invention relates to an inlet nozzle, which especially for the use in swimming pools is provided.

In swimming pools is it desirable at least two jets of water enter in different directions allow. As a result, for example, the lower water layer be fed with a jet of water within a swimming pool, thereby the soil deposited dirt on a floor drain box supply. On the other hand, the other water jet can be aligned that he a near-surface water flow generates so floating dirt particles in the direction of the skimmer to wash.

It is known to use for this task, two separate inlet nozzles, as taken for example from the DE 85 26 472.3 U1 are known.

adversely Here is that for each inlet a own pelvic wall passage must be provided whereby the necessary material and assembly costs are relatively high is. It is also disadvantageous that through the piping to the two pelvic wall ducts a not inconsiderable flow loss arises.

Of the Invention is therefore based on the object, an inlet nozzle in particular for a swimming pool to create the generation of at least two water jets allows.

These The object is achieved by the recited in claim 1 inlet nozzle.

Thereby, that the An inlet nozzle according to the invention Hollow spherical body comprises which consists of at least two parts, the parts being relative to each other about a rotation axis are rotatable, and each part at least an outlet opening comprises can the hollow ball body supplied water by rotating the parts to each other in different Directions are given. The direction of the single jet of water depends on the position of the respective outlet opening.

constructive it is preferred if the inlet nozzle comprises an insert on which the hollow ball body supported.

at a particularly preferred embodiment the inlet nozzle according to the invention is the Hollow spherical body in the middle, d. H. in the equatorial plane in two halves divided in two. Assign each of the halves, like particularly preferably, an outlet opening, then the inlet nozzle for generating two water jets suitable, whose directions by twisting the two halves around the perpendicular to the equatorial plane extending axis of rotation can be adjusted.

Especially preferred is a constructive variant of the inlet nozzle according to the invention, in which each of the halves of the hollow ball body having a recess with the corresponding recess the other half forms an inlet.

The Recess is preferably opposite to the respective outlet opening Side of a half of the hollow ball body provided such that the recess up over the equatorial plane extends. This embodiment allows a maximum pivoting range the two halves of the hollow ball body relative to each other, without thereby the generated by the inlet nozzle according to the invention Flow resistance essential elevated.

Around to avoid that along the parting planes of the parts of the hollow ball body supplied water uncontrolled can emerge, the parts of the hollow ball body preferably engage via tongue and groove joints each other. By this measure at the same time the axis of rotation to the two parts relative to each other can be twisted, set and allows a rotation of adjacent parts to each other, without it additional measures requirement.

at a particularly preferred embodiment the inlet nozzle according to the invention is the Hollow spherical body as a whole pivotally mounted in the insert. This measure can also the axis about which the parts of the hollow ball body rotatable relative to each other are pivoted, thereby adapting the directions of the emerging from the inlet nozzle Water jets not limited by a fixed axis of rotation are.

In the drawing is an embodiment of illustrated inlet nozzle according to the invention. It demonstrate:

1 - schematically and in part - the embodiment in cross section (section I - I in 2 );

2 the section II - II in 1 such as

3a) to f) several adjustment possibilities of the embodiment of the inlet nozzle according to the invention in a view from the front (view A in 1 ).

The in the drawing as a whole with 100 designated inlet nozzle comprises a hollow ball body 1 passing through an equatorial plane E in two halves 2 and 3 shared. The two halves 2 . 3 grip via groove / spring arrangements 4 . 5 in such a way that they are pivotable about a perpendicular to the equatorial plane axis of rotation D relative to each other. The groove / spring arrangements 4 . 5 are in this case designed such that the angle of rotation α, by which each of the halves of the in the 1 such as 3b and 3e shown center position can be pivoted in both directions, 30 ° is (see 3a . 3c . 3d . 3f ).

Every half 2 . 3 of the hollow ball body 1 has an outlet opening 6 . 7 on. Further, in each of the halves 2 . 3 a semicircular recess 8th . 9 on the outlet 6 . 7 Seen in the direction of flow opposite side of the respective half 2 . 3 of the hollow ball body 1 provided, which together with the other recess an inlet 10 formed. The outlet openings are related to the origin 11 of the inlet 10 each inclined at an angle β of 15 ° relative to the equatorial plane E.

each outlet opening has a diameter of 8mm to meet the KOK guidelines. These Guidelines state that one outlet opening for the reduction of accidents (Children could be in Trap of larger diameter put their fingers in) do not have a larger diameter should. However, it is also possible structurally, the outlet openings if necessary for to provide other purposes with a larger diameter.

The hollow ball body 1 relies so in an only schematically indicated use 12 that it as a whole is freely rotatable, as by the in 2 shown arrows P should be symbolized.
