Definitions
- the invention relates to a shower head with a water passage openings having bottom part made of an elastic material, the water passage openings Exit at the bottom of the shower head and over the bottom survive.
- shower heads can be found in almost every household as part of a shower head known for decades. Problems arise in particular with shower heads with hard to very hard tap water, from which very quickly and massively Eliminate limescale.
- the limescale deposits set the water passage openings and significantly impair the function of the shower head.
- EP-A-0 435 031 The principle known from EP-A-0 435 031 is based on a similar principle Shower head, at the bottom part of which there are hose-like outlet openings Material with a hardness of 20 to 100 shore are provided. By manual “rubbing" on the hose-like outlet openings should be in these deposited lime can be removed.
- the invention now goes a new way.
- shower head provided that the bottom part has an approximately ring-shaped Has projection that protrudes beyond the underside of the shower head and that the water passage openings along the length of the projection are distributed.
- the at least one ring segment but preferably the shape of a projection having a closed ring no longer carries the risk of damage, which is the case with the aforementioned extensions.
- the water passage openings are reinforced in such a way that the risk of damage to the bottom part when "rubbing" is not more exists.
- the annular projection can be easily made deform by manual “rubbing", whereby the lime particles in the Water passage openings detached and then fall out of them or be washed out.
- the bottom part at least one exposed at the bottom of the shower head at least has a water passage opening having a central section, which as Membrane is formed. Due to the elastic properties of the bottom part and the formation of the central section as a membrane, the water passage openings do not necessarily have to protrude over the underside of the shower head, can be a cleaning of the shower head from the lime particles in particular easily achieved by, for example, a finger over the membrane-like exposed, d. H.
- 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 a water supply 2.
- the shower head 1 is included a water passage openings 3 having bottom part 4.
- the Bottom part 4 consists of elastic material, preferably with a material hardness from 20 to 120 shore.
- the water passage openings 3 occur at the Bottom 5 of the shower head 1.
- the water passage openings 3 are, if at all, only very slightly over the bottom 5 of the shower head 1.
- the bottom part 4 itself is held in the shower head 1 and is in with the water supply 2 Connection.
- the bottom part 4 has at least one approximately ring-shaped Has projection 6, which over the bottom 5 of the shower head 1st protrudes, the water passage openings 3 over the length of the projection 6 are distributed.
- the projection 6 itself has at least one ring segment that extends over at least part of the underside 5 of the shower head 1 extends extensively.
- the projection 6 preferably has the shape of a closed ring on the circumference at the bottom 5 of the shower head 1 is arranged. Otherwise, it is also understood that the projection 6 can have the shape of an open ring.
- the ring-shaped projection which consists of solid material and only is penetrated by the water passage openings in some places due to the material properties of the bottom part 4 easily manually be deformed by "rubbing", which also changes the water passage openings 3 change in shape, which means that it is deposited Lime dissolves and is discharged.
- the water passage openings 3 occur in each case at the highest point of the projection 6, are at least in the circumferential direction surrounded by comparatively much elastic material of the bottom part 4, so that a break or damage to the projection when "rubbing" is not to be feared.
- the shower head 1 offers the water passage openings 3 over the circumference of the projection 6 to distribute evenly. It has been found that it is for good The blasting result is sufficient if the individual water passage openings 3 are spaced apart by an arc angle of 6 °. This way you get 60 Water passage openings 3, due to the function of the invention it is ensured that every 60 water openings after occasional "Rubbing" can be flowed through.
- the projection 6 is annular trained, but also the bottom part 4. So it's not necessarily required that the bottom part 4 over the entire surface of the bottom 5 of the shower head 1 extends. Because of the annular bottom part 4, it is possible the actual shower function in the area of the outer circumference of the shower head 1, while the central area for possible others Functions of the shower head 1 is available.
- the bottom part 4 has an area which is approximately U-shaped in cross section 7 on which in the embodiments of FIG. 1 (right representation) and Fig. 2 and 3 of the projection 6 connects.
- the bottom part 4 can be particularly simple Hold in a ring channel 8 provided in the housing of the shower head 1, which will be discussed in more detail below.
- the But bottom part 4 can also be designed as an annular disc to which the projection 6 joins downwards. Instead of a side clamp The bottom part 4 is then corresponding over the U-shaped area To hold or clamp in the housing of the shower head 1.
- the projection 6 is not only movable back and forth, but also in the shower head 1 can be pushed in.
- the water passage openings 3 have a narrowing in the flow direction Section 9 on.
- This narrowing section 9 acts in Art a Venturi nozzle, therefore leads to the acceleration of the water.
- the advantage this narrowing section 9 is that even at a low Amount of water a quite powerful water jet can be generated.
- the narrowing section 9 immediately adjoins the U-shaped one Area 7.
- the narrowing section 9 is in turn connected an outlet section 10.
- the outlet section is in its end region 11 10 beveled according to the desired water outlet direction.
- FIGS. 3, 4 and 5 shows that the outlet section 10 in its end region 11 with different water passage openings 3 can also be designed differently.
- this beam pattern is 10 times in Projection 6 provided so that thirty water passage openings 3 with a Inclination of 8 ° with respect to the vertical, twenty water openings with an inclination of 5 ° and ten water passages with an inclination of 2 ° are provided.
- the one in FIG shown end region 11 has a bevel 12 with an angle of 16 °, so that there is a water jet direction of 8 °.
- 4 shows the bevel 12 in the end region 11 at an angle of 10 °, so that there is a Water jet direction of 5 ° results.
- the water passage openings 3 are designed such that there is an equal flow rate regardless of the water jet direction results. This is realized in that the lower surface of the water passage openings 3 the desired requirements in the area of the outlet accordingly beveled at a small angle ⁇ of 0 to 1 ° is. This results in the area of the bevel 12 subsequent to the End region 11 a protrusion 13 through which the water passage opening narrowed.
- the inside and / or on the outside of the projection 6 and / or the base part 4 at least one bulge 14 provided.
- the bulges 14 are not only aesthetic Effect, because they give the impression of "rubbing" when stripping lime, but also serve to move the annular bottom part 4 to avoid within the shower head 1. 8 also shows and 9 that the water passage openings 3 at least on their outlet side End in a rectangular shape.
- FIGS. 10 to 13 are other embodiments of the shower head according to the invention 1 shown.
- the bottom part 4 in a lower support element 15 of the shower head 1 inserted and fixed in it.
- the main thing here is that the bottom part 4 has a central section 16 which is designed as a membrane.
- Water passage openings 3 can be aligned as described above.
- the design as a membrane makes it possible, with a correspondingly slight application of pressure to deform the membrane to the central portion 16, which for Removal of the lime deposited there leads.
- the base part 4 an area 7 of approximately U-shaped cross section.
- the middle section 16 lies between the two side legs of the U-shaped Area 7.
- the bottom part 4 is again designed as a ring, which is what the previously mentioned Has advantages.
- the middle section 16 stands over the bottom 5 of the shower head 1 over.
- the middle section 16 presses This is particularly easy if the middle section 16 and the bottom 5 merge into each other.
- the U-shaped region 7 or the bottom part 4 accidentally damaged.
- the central section of the area is also concave or can just be trained.
- a movement of the midsection can result from this result in water flowing through the shower head and the flow pressure on the inside of the central section acts so that it extends outwards bulges. If the water pressure changes now, this occurs due to the membrane properties a corresponding movement of the middle section, which also leads to limescale removal.
- the additional "scratching" to facilitate at least one knob 17 on the outside of the central section 16 may be provided, which over the underside 5 of the shower head 1 survives.
- FIGS. 14 and 15 While the annular design of the base part 4 from FIGS. 12 and 13 14 and 15, another embodiment is shown, in which basically also the central section 16 as a membrane is trained.
- FIGS. 14 and 15 applies to what has been said above with the exception that the bottom part 4 is not considered Ring is formed, has a plurality of middle sections that approximately are distributed over the entire underside 5 of the shower head.
- a plurality of openings 18 are provided in the corresponding Project U-shaped areas 7. Because of the U-shaped design, they are Areas flat and designed so that a user the middle sections 16th (with convex training).
