Definitions

  • the invention relates to a shower head with a water passage openings Bottom part made of an elastic material, the water passage openings emerge from the underside of the shower head and protrude beyond the underside.
  • shower heads can be found in almost every household as part of a shower head and have been for decades known. Problems arise with shower heads, especially with hard ones to very hard tap water, from which limescale accumulates very quickly and massively retire. The limescale clog the water passage openings and significantly impair the function of the shower head.
  • EP - A - 0 443 538 already discloses a shower head of the type described in the introduction known, with molded-on pins are provided through which the Water passage openings are passed through and over the bottom of the Survive shower head.
  • the shower head known from EP-A-0 435 031 is based on a similar principle, at the bottom part with hose-like outlet openings made of a material a material hardness of 20 to 100 Shore are provided. By manual “scratching" Lime deposited in the hose-like outlet openings is to be detached into this become.
  • Both EP - A - 0 443 538 and EP - A - 0 435 031 contain the Water through openings via spigot or hose-like extensions the bottom of the shower head over.
  • the problem with the well-known cones or hose-like extensions is that when manually "rubbing", especially due to the thin walls of the extensions, for kinking, Tearing or complete tearing of the extensions can occur.
  • the possibility of Removal of limescale will be significantly affected.
  • the invention now goes a new way. According to the invention is described in the beginning shower head provided that the bottom part has an approximately annular design Has projection that protrudes over the underside of the shower head, and that the water passage openings are distributed over the length of the projection. With the invention, the possibility of manual “rubbing” is still exploited to remove limescale deposits in the water passage openings. However, in the shower head according to the invention there is at least one Ring segment, but preferably having the shape of a closed ring Head start no longer the risk of damage occurring with the aforementioned Extensions are given. Due to the all-round projection, the water passage openings are so amplified that the risk of damage to the bottom part no longer exists when "scratching". Because the projection is made of the same elastic Material is like the bottom part, the annular projection can be made without further deform by manual "rubbing" elastically, whereby the lime particles in detached from the water passage openings and then fall out of them or flushed out become.
  • a shower head 1 according to the invention is shown in cross-sectional view.
  • the shower head 1 the basic structure of which is known per se, has one Water supply 2 on. Furthermore, the shower head 1 with a water passage openings 3 having bottom part 4 provided.
  • the bottom part 4 consists of elastic Material, preferably with a material hardness of 20 to 120 Shore.
  • the water passage openings 3 emerge from the underside 5 of the shower head 1. Moreover are the water passage openings 3 at least in the right embodiment 1 on the underside 5 of the shower head 1. At the in the 1, left-hand embodiment, in contrast, are the water passage openings 3, if at all, only very slightly over the bottom 5 of the shower head 1 over.
  • the bottom part 4 is held in the shower head 1 and stands with the Water supply 2 in connection.
  • the bottom part 4 has at least one approximately ring-shaped Has projection 6 which protrudes over the underside 5 of the shower head 1, wherein the water passage openings 3 distributed over the length of the projection 6 are arranged.
  • the projection 6 has at least one ring segment, which is extends at least over part of the underside 5 of the shower head 1.
  • the projection 6 preferably has the shape of a closed ring, which is arranged circumferentially on the underside 5 of the shower head 1.
  • the projection 6 have the shape of an open ring can.
  • the water passage openings 3 occur at the highest point of the projection 6, are at least in the circumferential direction of comparatively much elastic Surround the material of the bottom part 4, so that a break or damage the projection 6 when "rubbing" is not to be feared.
  • the shower head 1 In order to ensure a good water distribution of the shower head 1, it offers itself on, the water passage openings 3 evenly over the circumference of the projection 6 to distribute. It has been found that it is sufficient for a good blasting result is when the individual water passage openings 3 by an arc angle are spaced from 6 °. In this way you get 60 water openings 3, wherein the function of the invention ensures that always flows through all 60 water openings 3 after occasional "rubbing" become.
  • the projection 6 is annular trained, but also the bottom part 4. So it is not absolutely necessary that the bottom part 4 over the entire surface of the underside 5 of the shower head 1 extends.
  • the ring-shaped base part 4 makes it possible to perform the actual shower function to move in the area of the outer circumference of the shower head 1, while the central area for possible other functions of the shower head 1 for Available.
  • the base part 4 has a Cross-section approximately U-shaped area 7, to which in the embodiments 1 (right illustration) and FIGS. 2 and 3 of the projection 6 connects. Due to the U-shaped design of the area 7, the bottom part 4 can be formed in provided in a particularly simple manner in a in the housing of the shower head 1 Hold ring channel 8, which will be discussed in more detail below. Moreover can the projection 6 due to the U-shaped region 7 in the shower head 1st press in, which makes it easier to remove limescale. It is understood that the bottom part 4 but can also be designed as an annular disc to which the Projection 6 connects downwards.
  • the bottom part 4 is then in a corresponding manner in the housing in a U-shaped region to hold or clamp the shower head 1. It is important that the projection 6 not only movable back and forth, but also pushed into the shower head 1 is.
  • the water passage openings 3 have a narrowing in the flow direction Section 9 on.
  • This narrowing section 9 acts like a Venturi nozzle, thus leads to the acceleration of the water.
  • the advantage of this narrowing Section 9 is that even with a small amount of water a right powerful water jet can be generated.
  • the narrowing section 9 connects directly to the U-shaped area 7.
  • On the narrowing Section 9 is followed by an outlet section 10. In its end region 11 is the Exit section 10 beveled according to the desired water outlet direction.
  • a comparison of FIGS. 3, 4 and 5 shows that the outlet section 10 in its end region 11 also different with different water passage openings 3 can be trained.
  • a periodically repeating one Jet pattern with water jet directions of the individual water passage openings 3 of 8 °, 5 °, 8 °, 5 °, 8 ° and 2 ° is provided (see FIG. 6).
  • this beam pattern is provided ten times in the projection 6, so that thirty water passage openings 3 with an inclination of 8 ° relative to the Vertical, twenty water passage openings 3 with an inclination of 5 ° and ten water passage openings 3 are provided with an inclination of 2 °.
  • the The embodiment shown in FIG. 3 has an end region 11 Bevel 12 at an angle of 16 ° so that there is a water jet direction of 8 ° results.
  • the bevel 12 has an angle in the end region 11 from 10 ° to a water jet direction of 5 °.
  • the bevel 12 under a Angle of 4 ° inclined from the vertical so that there is a water jet direction of 2 ° results.
  • the narrowing section 9 is at each individual water passage opening 3 equal.
  • the outlet section 10 at the individual water passage openings 3 differently designed, the end region 11 longer or shorter.
  • the water passage openings 3 are designed such that they are independent gives an equal flow rate from the water jet direction. This is because of it realizes that the lower surface of the water passage openings 3 in the region of the outlet according to the desired requirements at a small angle ⁇ is chamfered from 0 to 1 °. This results in the area of the bevel 12 after the end region 11, a protrusion 13 through which the water passage opening 3 narrowed.
  • the Water passage openings 3 at least at their outlet end Have a rectangular shape.
