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 water connection passing into the handle on the one hand and into the housing on the other hand and a base plate made of plastic, in which water jet nozzles are formed.
  • shower heads are used in the sanitary area both for the shower and bathtub, but also for other purposes. They are also known, for example, in a correspondingly tailored form for the water basin in the kitchen area.
  • the shower head of shower facilities tends to clog, particularly in areas where the lime content in the water is high. Lime accumulates in the area of the water jet nozzles and there in the outlet area, which can usually only be removed mechanically, because the precipitated lime becomes so hard that it no longer escapes due to the water that later emerges again with the appropriate flow rate and pressure is washed away with.
  • the base part consists of a plastic composite material, the water jet nozzles being molded onto a plastic carrier plate (DE OS 43 08 599.7).
  • DE OS 40 39 337.2 describes a self-cleaning shower head in which an elastic jet former is assigned to the base part made of elastic material in order to achieve an elastic deformation on the jet former when pressurized with pressurized water.
  • the invention is therefore based on the object of providing an easy-to-clean shower head which has an optimized radiation pattern.
  • the base plate has several rows of water jet nozzles, the outlet opening of which has a bulge in the water outlet direction.
  • the base plate made of plastic therefore has corresponding bulges in the area of the water outlet openings, where the lime can accumulate. Due to the existing conditions, it can be easily wiped off these areas where it attaches without affecting the effect of the water jet nozzle. Even if there is no longer appropriate cleaning, the jet pattern of the water jet nozzles is retained because the deposit takes place in a part where it can no longer directly influence the jet.
  • a particularly useful design provides that the bulge of the outlet openings is elliptical, so that there is an attachment area for the fixing inclined lime material shows that the different distance to the edge of the outlet openings is different, which in turn makes cleaning much easier. It is known that a "weak point" layer of deposits can be detached more easily than a coating with uniform deposits.
  • the effect of the bulge is particularly favorable if the bulges are elliptical in plan view and hemispherical in section. It is not necessary to actually form a hemisphere, but a portion of it is sufficient, only that appropriately rounded shapes are produced which facilitate easy cleaning.
  • the base plate is designed as an annular disc and is mounted on the one hand in the edge of the housing and on the other hand in the middle part.
  • Such an annular disc can be the one that occurs Absorb forces much better than a continuous base plate, whereby the rays emanating from the ring plate ensure that the body parts are evenly acted upon and are generally perceived as pleasant.
  • This washer is mounted on the one hand in the edge of the housing and on the other hand in the middle part, i.e.
  • the base plate has a groove on the edge side, in an O-ring sealing against the housing edge or the middle part is mounted.
  • the two O-rings are arranged so that they ensure the necessary tightness and on the other hand ensure that the annular base plate is securely mounted.
  • the hole pattern of the base plate is characterized in that the water outlet nozzles on the base plate or annular disc are offset in two rows from one another on jets passing through the center of the circle of the base plate. Due to the slight offset of the individual water outlet nozzles or their bulging, the individual bulges are acted upon one after the other during wiping, so that the cleaning effect is thus improved.
  • this results in a very useful hole pattern with a supplementary illustration also interpreting the arrangement in such a way that the water outlet nozzles are arranged in groups of four in an arc running from the inner edge to the outer edge.
  • the water outlet nozzles have different outlet angles depending on the distance from the edge of the housing, the basic flow direction or jet direction being predetermined, of course, and being approximately perpendicular to the central axis of the shower head.
  • a further optimization of the cleaning possibility is provided by a design according to which the base plate or annular disc is formed with the central part to form an outwardly curved spherical surface, which means that the individual outlet openings of the water jet nozzles lie in different planes and are therefore less expensive to clean and for give others an optimized hole pattern or radiation pattern.
  • the uniform water jets act due to the exit angle and the exit plane so that the effect described is maintained even after a long period of inactivity.
  • the base plate or the ring disk consists of a plastic with a Shore hardness of around 90, preferably TPE.
  • TPE thermoplastic polyethylene
  • the invention is characterized in particular by the fact that a shower head is created which can be kept relatively simple in construction, but is nevertheless easy to clean with regard to the limescale deposits.
  • a shower head is created which can be kept relatively simple in construction, but is nevertheless easy to clean with regard to the limescale deposits.
  • it has an optimized hole pattern that not only makes cleaning easier, but at the same time also specifies the formation of a jet to form an advantageously uniform overall jet.
  • the shower head also has a favorable service life and, if necessary, also allows the base plate with the water jet nozzles to be replaced if this should become necessary during the entire operation. However, it is not necessary to replace the entire shower head.
  • a shower head provided for the shower area which can also be used in other areas as well, is provided with the reference number 1 in FIG. 1.
  • This shower head 1 has a disk-shaped housing 2, into which the water connection 3 opens at the top.
  • a bottom plate 4 is clamped, the special features of which will be discussed further below.
  • the base plate 4 is equipped with a large number of water jet nozzles 5, 6, 7, all of which basically have the same shape, although the exit angle depends on the plane in which the outlet opening 10 of the individual water jet nozzles 5, 6, 7 is arranged, can be different.
  • the middle part 8 of the base plate 4 also serves as a holder for the actual base plate 4, which is designed here as an annular disk.
  • This middle part 8 is fixed to the housing 2 by means of the fastening 9, whereby, as already mentioned, the annular base plate 4 is supported at the same time.
  • the individual outlet openings 10 of the water jet nozzles 5, 6, 7 have a bulge 12 in the water outlet direction 11, which is indicated in FIG. 1, but can be seen particularly clearly from FIG. 4.
  • This bulge 12 is hemispherical in order to avoid straight, rugged edges. This makes cleaning limescale deposits much easier.
  • the individual water jet nozzles 5, 6, 7 are each arranged in rows 15 and 16, the details of the hole pattern in FIG. 2 being apparent and also being described in more detail in the context of the explanations for FIG. 2.
  • the base plate 4 is clamped between the housing edge 22 and the central part 8.
  • the bottom plate 4 has a groove 23, 24 of the same design on both edges, an O-ring 25 being mounted in each of these grooves in order to seal this area and to ensure that all the water is only available via the water jet nozzles 5, 6, 7 can leave the area of the shower head.
  • FIGS. 2 and 3 The shape of the individual bulge 12 is illustrated in FIGS. 2 and 3, with FIG. 3 an enlarged representation of a the bulges 12. It can be seen here that the bulge is in the form of an ellipse, the beam 20 passing through the center of the circle 19 intersecting both focal points 17, 18 of this ellipse. As explained in FIG. 3, the outlet opening 10 is displaced in the direction of the focal point 17, so that there is a different distance between the individual bulging areas and the outlet opening 10 or its edge 13.
  • Fig. 2 illustrates that the individual bulges 12 or water jet nozzles 5, 6, 7 are each combined into two rows 27, 28, with the associated two water jet nozzles 5 'and 6' being offset from one another in each of these two rows 27 and 28.
  • Fig. 2 also illustrates that the individual water jet nozzles 5, 6, 7 are combined into groups of four 31, 32 which are evenly distributed on a fleeing sheet 35 pointing from the inner edge 33 to the outer edge 34. This results in the effect already described that none of the water jet nozzles 5 lies exactly on the same jet 20, 20 ', 20' ', but rather in each case offset on its own jet or, moreover, again on the sheet 35 described.
  • the hole pattern of the base plate 4 described provides, on the one hand, an optimized overall jet of the shower head 1 and, on the other hand, a relief when cleaning. This cleaning also complies with the arrangement of the individual bulges 12 - with the narrow side directed towards the cleaning direction - if one assumes that the cleaning cloth or whatever is moved in a circle during cleaning.
  • the special design of the base plate 4 corresponds to FIG. 1 that the base plate 4 in the form of the annular disc and the central part 8 form a spherical surface 30, so that the individual water jet nozzles 5, 6, 7, as shown in FIG. 1, yes illustrates exiting in different levels of the base plate 4.
