Definitions

  • the invention relates to a shower head according to the preamble of claim 1.
  • Such a shower head is in the DE 31 07 806 C2 described.
  • the valve elements which are associated with the passages of the perforated plate, in the pressure-free state of the shower head, the shape of cones whose tips are squeezed wide. So you have each a pinch valve, which is not biased by an external squeeze but by elastic self-bias in the closed state.
  • the individual valve elements open to substantially cylindrical pieces of tubing.
  • valve elements no longer reliably close after prolonged use, so that there is a dripping of water from the shower head after switching off the water supply.
  • a shower head according to the preamble of claim 1 is to be further developed such that a secure closing of the individual valve elements after completion of the pressurization of the shower head is obtained.
  • the individual valve elements are formed by membrane sections, which each have a curved shape. These curved membrane sections each have at least one cut. The cut edges are in pressure-free shower head firmly and close to each other. However, the cut is opened by deformation of the curved membrane portion when the interior of the shower head is pressurized.
  • valve elements build short in the axial direction. So you do not need to get over the perforated plate. Since the valve elements are relatively deformed geometrically relatively strong in the opening and closing movement, in particular, the edges of the sections of the curved diaphragm sections are moved away from each other with great force when the shower head is pressurized, and return to the closed position with great force when the pressurization of the shower head is completed, deposits that could form in the region of the valve elements, reliably dropped, without the need for an additional applied by the user mechanical force would be necessary.
  • valve elements provided in the shower head according to the invention can also be produced inexpensively.
  • a membrane with the arched membrane sections can be easily produced with a two-part mold, which has only a few draft angles and is completely or largely free of undercuts. It is thus also possible to produce the membrane by deep-drawing or blow-molding from a corresponding starting mat or starting film and is not dependent on a spraying process.
  • the cuts in the arched membrane sections can be created by a simple cutting tool.
  • the development of the invention according to claim 3 is in view of a good mechanical stability of the curved membrane sections at the beginning of pressure increase advantage.
  • the sections of the individual arched membrane elements are thus only then opened suddenly when the pressure inside the shower head has reached such a value that even the curved membrane section can no longer withstand it.
  • the effect just described is particularly pronounced when providing the concave side of the curved membrane portion at the front of the shower head, so that the convex side of the curved membrane portion facing the inside of the shower head.
  • valve elements in the axial direction of the passage openings of the perforated plate are movable.
  • This outward movement of the domed membrane sections having the cuts can be done under relatively little force since bellows cuts or rolling diaphragm sections provide little resistance to axial movement.
  • the opening of the valve elements takes place in a position in which they are adjacent to the front side of the perforated plate or in which they already protrude beyond the front of the perforated plate. In this way it is prevented that accumulated by the valve element deposits accumulate inside the perforated plate.
  • the development of the invention according to claim 7 is in view of the use of Balgabitesen of advantage, which have no extremely small radii of curvature and need not be extremely thin. This is in terms of the life of the Balgabitese and thus the membrane element of advantage.
  • An elastomeric material as indicated in claim 8, is suitable for the realization of membrane elements with curved membrane sections, which are provided with control cuts, particularly proven.
  • FIG. 1 designates a shower head as a whole, which has a cup-shaped housing part 12 which is closed by a perforated plate 14.
  • a membrane element 16 is clamped between the housing part 12 and the perforated plate 14. This is provided with a plurality of valve elements 18, which are indicated in the sectional view of the shower head gestrichtelt only by their common front boundary line.
  • the housing part 12 has an inlet opening 20 which is connected to a feed channel of a handle not shown in detail the shower head communicates.
  • the latter is z. B. via a flexible hose with a building fixed connection in connection, which is acted upon by a mixing valve with warm water.
  • valve elements 18 Details of the valve elements 18 will now be explained with reference to the detail enlargement of FIG.
  • the passage 24 is substantially cylindrical, its interior facing the 22 facing edge is rounded.
  • the membrane element 16 has a membrane section extending into the interior of the passage 24, which has an axially short frusto-conical peripheral wall 26 and a dome-shaped bottom wall 28.
  • the bottom wall 28 has with its convex side to the interior 22, with its concave side to the outside of the perforated plate 14th
  • bottom wall 28 In the bottom wall 28 four cuts 30 are provided, which are equally distributed in the circumferential direction and extend from the axis of the bottom wall 28 to the edge thereof.
  • the bottom wall 28 is thus divided into four sectors of 90 ° each.
  • the water in the interior space 22 seeks to move the sectors of the bottom wall 28 in the axial outward direction. This initially does not succeed geometrie employment. As the pressure in the interior space 22 has risen sharply, however, the supporting force of the dome-shaped bottom wall 28 is exceeded and its four sectors are abruptly moved axially outwardly under flexing. Now, the valve element 18 is opened and through the passage 24, water is discharged.
  • the membrane element 16 may have a thickness of 0.7 to 1.5 mm and be made of an elastomeric material having a Shore hardness of 70 to 90.
  • the elastomeric material may be rubber or synthetic rubber.
  • valve elements 18 are arranged completely behind the front side of the perforated plate 14.
  • the shower head 10 according to FIG. 2 operates on the same basic principle as that shown in FIG. Components that fulfill the same function are again provided with the same reference numerals, although in detail have different geometry. Hereinafter, only the differences of the shower head according to Figure 2 to those of Figure 1 need to be explained.
  • the bottom wall 28 is supported by a peripheral wall 26, which is slightly curved outwards (barrel-like) is formed. It is thereby achieved that the peripheral wall 26 is centered in the passage 24, but nevertheless frictional forces between the outer surface of the peripheral wall 26 and the inner surface of the passage 24 remain small, since there is no extensive areal contact.
  • the peripheral wall 26 is formed at its upper end to a rolling diaphragm or bellows portion 32 of the membrane element 16.
  • the bellows portion 32 is received in an enlarged counterbore 34 of the passage 24 recording. It is integrally formed on the membrane element 16 at its upper end.
  • the same materials can be used as have been mentioned above with reference to the exemplary embodiment according to FIG. Also you will get the wall thickness and geometry of the bottom wall 28 similar.
  • the material thickness can be chosen slightly lower in order to ensure a slight rolling of the bellows.
  • the wall thickness should not be too low there, so that the peripheral wall 26 is retracted together with the bottom wall 28 again under elastic prestress when the pressurization of the interior 20 is terminated.
