Definitions

  • the invention relates to a shower head, in particular for the sanitary area and there for the shower, with a disc-shaped housing, the one hand in the handle and on the other hand, water connection passing into the housing and a base plate with several rows of water outlet openings.
  • Such shower heads are both in the sanitary area for the area of the shower and the bathtub, but also for other purposes. They are known for example in appropriately tailored shape also for the water basin in the kitchen area.
  • the shower head of shower facilities is prone to constipation, especially in areas where the lime content in the water is high. It sits in Lime outlet area, which is usually only mechanical can be removed because the precipitated lime hard so far is that he also later with the appropriate Water flow and pressure escaping no longer is washed away with.
  • the water jet nozzles molded onto a plastic carrier plate are (DE OS 43 08 599.7).
  • the water jet nozzles are part of one on the bottom plate supporting elastic nozzle plate.
  • DE OS 40 39 337.2 describes a self-cleaning shower head in which the an elastic base part made of elastic material Beamformers are assigned to act upon Pressurized water to an elastic deformation on the jet to reach.
  • the invention is therefore based on the object easy to clean, with an optimized spray pattern To create shower head.
  • the Base plate made of a Shore hardness of around 90
  • the water outlet openings bulges each arranged in the water outlet direction has an ellipse in plan view and in section are hemispherical.
  • the plastic one So bottom plate has in the area of the water outlet openings about corresponding bulges, where if the lime can deposit. Because of the existing conditions can he from these areas where he sits, can be easily wiped off without the effect of the water jet nozzle to influence. Even if not for a long time is cleaned accordingly, the jet pattern of the water jet nozzles remains received because the deposit is in one part takes place where they no longer directly influence the beam can.
  • the arching of the outlet openings is elliptical is formed so that there is an attachment area for gives the lime material that tends to stick, which is caused by the different distance to the edge of the outlet openings differently coated with lime, which in turn cleaning is made much easier. It is known that a "weak point" layer of deposits can be removed more easily than even deposits coating. After all, it is not no matter which plastic as material for the base plate it is a possibility.
  • the base plate consists of one Shore hardness of around 90 plastic. At a such plastic material is with sufficient elasticity ensures a sufficient service life and above all that necessary surface ensures the limescale deposits peel off easily and safely, or even wipe it off can.
  • the base plate is designed as an annular disc and on the one hand in the housing edge and on the other hand in the middle part is stored.
  • Such an annular disc can be the one that occurs Absorb forces much better than a continuous one Base plate, the rays emanating from the ring plate an even application to the body parts ensures and is even generally perceived as pleasant.
  • This washer is on the one hand in the housing edge and on the other stored in the middle section, d. H. together with the Middle part can be assembled and disassembled, taking the necessary Tightness is guaranteed if as according to the invention after a further training is provided, the bottom plate has a groove on the edge in which one against the Housing edge or the middle part sealing O-ring stored is. The two O-rings are arranged so that they are for ensure the necessary tightness and on the other hand ensure that the annular base plate is securely mounted becomes.
  • the hole pattern of the base plate is according to the present Invention characterized in that the water outlet nozzles on the base plate through the center of the circle Base plate rays, offset in two rows to each other are trained. Due to the slight offset of the individual water outlet nozzles or their bulging the individual bulges are applied one after the other when wiping, so that the cleaning effect is improved. This also results in a very useful hole pattern, whereby a supplementary illustration also interprets the arrangement that the water outlet nozzles in groups of four in an arc running from the inner edge to the outer edge are arranged.
  • the basic flow direction or jet direction of course is specified and approximately at right angles to the central axis of the shower head runs.
  • a further optimization of the cleaning possibility serves a training, according to which the base plate with the middle part forming an outwardly curved spherical surface is what causes the individual outlet openings of the Water jet nozzles are in different levels and thus are cheaper to clean once and the other one result in an optimized hole pattern or jet pattern.
  • the uniform Water jets act due to the exit angle and the exit level so that even after a long time Service life the effect described is maintained. Furthermore there is of course always the option of adding the washer extreme pollution or even in the event of damage, to be optimal again in this way to get a functional shower.
  • the ring disc has the necessary service life, because the actual area of the TPE plastic Washer and the protruding bulges not by the Cleaning can be damaged.
  • the invention is characterized in particular by that a shower head is created, which is proportional in construction is simple, but still easy in terms of Limescale is to be cleaned. He also has via an optimized hole pattern that is not just cleaning relieved, but at the same time the beam formation too specifies an advantageously uniform overall jet.
  • the shower head has a favorable service life and also enables an exchange of the Bottom plate with water jet nozzles, if this during of the entire operation should become necessary. It is against no need to replace the entire shower head.
  • a shower head intended for the shower area, the but can also be used in other areas can be provided with the reference symbol 1 in FIG. 1.
  • This shower head 1 has a disc-shaped housing 2, in that opens up the water connection 3.
  • a bottom plate 4 clamped on their special features further back is received.
  • the base plate 4 has a large number of water jet nozzles 5, 6, 7, which in principle all the have the same shape, but with the exit angle depending on the level in which the outlet opening 10 of the individual Water jet nozzles 5, 6, 7 is arranged differently can be.
  • the middle part 8 of the base plate 4 serves at the same time as a holder for the actual base plate 4 as here Washer is formed. This middle part 8 is about Attachment 9 fixed to the housing 2, at the same time thus, as already mentioned, the annular base plate 4 is supported becomes.
  • the individual outlet openings 10 of the water jet nozzles 5, 6, 7 have a in the water outlet direction 11 Bulge 12, which is indicated in Fig. 1, but Fig. 4 can be seen particularly clearly.
  • This bulge 12 is hemispherical to avoid straight, rugged edges. This makes cleaning limescale deposits essential facilitated.
  • the individual water jet nozzles 5, 6, 7 are each in Rows 15 and 16 arranged, the details of the Hole pattern Fig. 2 can be taken and in the context of Explanations to Fig. 2 are also described in more detail.
  • the bottom plate 4 is according to FIG. 1 between the edge of the housing 22 and middle part 8 clamped.
  • the bottom plate 4 has both edges via a groove 23 of the same design, 24, an O-ring 25 being mounted in each of these grooves, to seal this area and ensure that the all water only via the water jet nozzles 5, 6, 7 den Can leave the area of the shower head.
  • FIG. 2 and FIG. 3 The shape of the individual bulge 12 is illustrated in FIG. 2 and FIG. 3, wherein FIG. 3 is an enlarged representation of a the bulges 12. This shows that the bulge has the shape of an ellipse, the by the Circular center 19 going beam 20 both focal points 17, 18 intersects this ellipse.
  • the outlet opening 10 is like 3 explains, shifted in the direction of the focal point 17, so that a different distance between the individual bulge areas to the outlet opening 10 or its edge 13 given is.
  • Fig. 2 illustrates that the individual bulges 12th or water jet nozzles 5, 6, 7 each in rows of two 27, 28 are summarized, with each of these rows of two 27th and 28 the associated two water jet nozzles 5 'and 6' are staggered.
  • Fig. 2 also illustrates that the individual water jet nozzles 5, 6, 7 combined into groups of four 31, 32 that are on one from the inner edge 33 to the outer edge 34 pointing, fleeing bow 35 arranged evenly distributed are. This results in the effect already described, that none of the water jet nozzles 5 are exactly on the same Beam 20, 20 ', 20' 'is, but rather offset on its own beam or, and beyond, again on the described sheet 35.
  • the hole pattern of the base plate 4 described provides for an optimized overall jet of the shower head 1 and on the other hand, it makes cleaning easier. This purge the arrangement of the individual bulges also accommodates 12 - with the narrow side facing the cleaning direction - if you assume that cleaning is usually done the cleaning rag or whatever in a circle is moved.
  • the special design of the base plate 4 corresponds 1 that the bottom plate 4 in the form of the annular disc and the middle part 8 form a spherical surface 30, so that the individual water jet nozzles 5, 6, 7, as shown in FIG. 1, yes illustrates in different levels of the base plate 4 emerge.
