Definitions

  • a surge device of the type mentioned, which is intended for use in overhead showers, is in DE 26 19 415 C2 described.
  • An attempt is made here to produce a "stable" water curtain by bending the flow path between the inlet into the housing and the outlet slot and by continuously changing the shape of the housing from a circular cross section to a slot-shaped cross section.
  • supporting, flow-conducting ribs are used, which are integrally formed on the inside of the housing.
  • Object of the present invention is to provide a surge device of the type mentioned in such a way that a highly stable water curtain is achieved, which can fall freely over a relatively large distance before it is divided or coincident.
  • the final calming and evening out of the water flow is rather when passing through a type of "weir", which is formed by a wall portion in the interior of the housing, which leaves a passage gap to an adjacent outlet space. About this gap occurs in the outlet space, which contains the actual outlet slot, at all points over the longitudinal extent of water in virtually pressure-free state, which is vortex-free and transported at all points the same volume per unit time.
  • This water can now pass through the outlet slot in the highest uniformity and fall down as a closed, stable curtain.
  • the outlet slot is arcuately curved. In this way, it is possible to produce a very long, water-rich curtain of water in a surge device whose dimensions are not too large.
  • the housing is formed of a lower housing part and a lid connected by a plug connection with the lower housing part.
  • This two-part design of the swelling device facilitates their manufacture and assembly, wherein it does not depend on an absolute tightness between the two housing parts to be joined together. In general, this is sufficient for a labyrinth seal. Possibly. But the two housing parts can also be welded tight after plugging together.
  • the outlet slot on the outside of the housing is surrounded by a rib.
  • Schwall pleaseden of interest here type are indeed within an outer housing, z. B. housed within the viewing housing of the shower or the outlet fitting.
  • the rib surrounding the outlet slot in this case passes through the visual housing of the shower or the outlet fitting, while all other parts of the surge device are hidden by this viewing housing.
  • the the sight housing penetrating rib prevents the water curtain leaving the outlet slot must flow past interfaces that could jeopardize the internal stability of the water curtain.
  • a further improvement of the quality of the water curtain is achieved by that embodiment of the invention in which a distribution space is arranged in the flow path between the vestibule and the storage space, which is connected to the storage space via an opening in an intermediate wall portion, which approximately in the middle of Longitudinal extent of the storage space is located.
  • This configuration ensures that the water distribution within the storage space is at least approximately symmetrical, which also reduces pressure differences within the storage space to a minimum.
  • Figure 1 The illustrated in Figure 1 and generally designated by the reference numeral 1 Schwullinutter is intended for installation in a Kopfschwallbrause. It comprises a housing 2, which is substantially kidney-shaped and is composed of a lower housing part 3 (Figure 3) and a lid ( Figure 2).
  • azimuthal is used for structural components that run substantially parallel to the arcuately curved side walls of the housing 1 and the term “radial” for those structural components that run essentially perpendicular to these azimuthal structural components, although the "azimuthal" building components do not form true circular arcs.
  • the lower housing part 2 has at one end a water inlet 4, which can be connected to a Wasserzuflußrohr, not shown.
  • a water inlet 4 Through the water inlet 4, the inflowing water passes into an antechamber 5, which extends in the azimuthal direction by about 40% of the total extent of the housing lower part 2.
  • a radially extending inner wall portion 6 and an integrally formed on this azimuthal wall portion 7 narrows the vestibule 5 in Figure 3 to the right in a narrower, also azimuthally extending distribution space 8.
  • Approximately in the middle of its longitudinal extension of the azimuthal wall portion 7 has a height reducing rectangular recess 9.
  • Parallel to the azimuthal wall portion 7 extends with a slightly larger "radius” another azimuthal wall portion 10, which starts from the radial wall portion 6 and extends to the right in Figure 3 end wall 11 of the housing base 2. While the wall portions 6 and 7 have a height at which they abut substantially after cultivation of the lid 3 to the inner surface of the lid 3, the height of the azimuthal wall portion 10 is slightly reduced, so that after the attachment of the lid 3 to the lower housing part. 2 between the inner surface of the lid 3 and the top of the azimuthal wall portion 10 remains a uniform gap. Between the wall sections 7 and 10 is an azimuthally extending storage space 12, between the azimuthally extending wall portion 10 and the azimuthally extending boundary wall of the lower housing part 2, which has the larger diameter, an outlet space thirteenth
  • a projecting rib 14 Along the entire upper end face of all boundary walls of the housing base 2 extends a projecting rib 14. At the bottom of the vestibule 5, two hollow cylindrical projections 15 and 16 are formed.
  • the lid 3 of the swelling device 1 shown in Figure 2 has a shape complementary to the housing part 2. On the inside of the lid 3, a parallel to the outer contour extending rib 17 is also formed. The inner surface of the lid 3 also carries two projecting pins 18 and 19th
  • the lid 3 is penetrated by an azimuthally extending, narrow outlet slot 20 in a region which corresponds to the outlet space 13 of the housing lower part 2 in the assembled state.
  • the outlet slot 20 on the outside of the lid 3 is surrounded by a protruding rib 21.
  • the top of the lid 3 carries a plurality of stiffening ribs 22, 23, 24, 25, 26, which are aligned substantially radially.
  • the pins 18 and 19 are introduced on the inside of the lid 3 in the holes of the hollow cylindrical projections 15, 16 of the housing part 2.
  • the rib 14 of the lower housing part 2 surrounds the rib 17 of the lid 3 and thus forms a positive connection and a kind of labyrinth seal, wherein it on a absolute tightness does not matter. Nor is it necessary that it comes between the top of the wall portions 6 and 7 of the housing base 2 and the inner surface of the lid 3 to a complete seal.
  • the finished surge device 1 is introduced into the visual housing, not shown, a surge shower, wherein the rib 21 passes through a corresponding gap of this view housing, while all other housing parts of the surge device 1 are hidden by the viewing housing of the shower.
  • the surge device 1 is arranged so that the outlet slot 20 faces downward.
  • the overhead shower which contains the described surge device 1, it is supplied via the water inlet 4 water, which flows through the antechamber 5 in the distribution chamber 8. From there, the water passes through the recess 9 in the azimuthally extending wall portion 7 in the storage space 12, where it is distributed over the entire azimuthal length.
