Definitions

  • the invention relates to a shower head for a sink mixer or the like, which is suitable for connection to a low-pressure store (open hot water tank), with a water inlet, a central jet outlet, in particular a centrally arranged outlet, and a shower outlet with a large number, in particular, concentrically surrounding the normal jet outlet small shower holes and a diverter valve, the diverter valve connecting the normal spray outlet with the water inlet in a normal position and separating the shower outlet from the water inlet and connecting the shower outlet with the water inlet in a shower position and separating the normal jet outlet from the water inlet.
  • a low-pressure store open hot water tank
  • the known shower head from which the invention is based (IDEAL STANDARD brochure "CERAMIX COMBI" W 538 2 S) is intended and suitable in particular for a sink mixer, but a corresponding design of a shower head can also be used on other batteries, in particular mixer taps Find. It is essential for such a shower head that it allows operation in two types of spray, namely on the one hand with a normal spray and on the other hand with a spray spray.
  • the normal jet emerges at a normal jet outlet through a conventional turbulator or the like.
  • the shower jet on the other hand, exits through a large number of small shower holes in a shower spout. In most cases, shower holes in the shower spout are arranged concentrically around the normal jet outlet.
  • a bypass line which is effective in the shower position is provided between the water inlet and the normal jet outlet in the diverter valve and that the flow resistance of the bypass line is greater than the flow resistance of the shower outlet when not added shower holes, but the maximum dynamic pressure occurring upstream of the bypass line when shower holes are added is less than the burst pressure of an associated low-pressure accumulator. It goes without saying that such a shower head is fully suitable for connection to a low-pressure accumulator due to the design according to the invention, but it can also be used with differently connected sink batteries or the like.
  • a first part of the invention lies in the knowledge that the bursting of a low-pressure accumulator when switching over to a shower head of the type in question can occur when the shower holes in the shower spout are completely or largely clogged by dirt or limescale deposits.
  • the bypass line When switching from the normal position to the shower position in the case of clogged shower holes, the bypass line fluidically takes over the function of the shower outlet largely or entirely, even if, due to the higher flow resistance, at a higher pressure level than with non-clogged shower holes.
  • the flow resistance of the bypass line is dimensioned in such a way that a pressure shock which becomes dangerous for the low-pressure accumulator cannot occur.
  • the shower head 1 shown in FIGS. 1 and 2 is intended and suitable for a sink mixer 2, which can be a mixer tap, in particular a single-lever mixer tap, as shown, but which can also be a pure cold water or a pure hot water battery. Such a shower head can also be used for other fittings, in particular other mixer taps.
  • the shower head 1 which can be seen in FIG. 1 has a handle 3 on which this shower head 1 can be handled.
  • the handle 3 is followed by a hose, which cannot be seen here, which runs into the interior of the sink mixer 2, so that the shower head 1 can be handled relatively freely.
  • the shower head 1 according to the invention is intended and suitable for a sink mixer 2 or the like, which is intended to be particularly suitable for connection to a low-pressure accumulator (open hot water accumulator).
  • a low-pressure accumulator open hot water accumulator
  • a shower head 1 according to the invention can also be used in conjunction with other water supply systems.
  • the shower head initially has a water inlet 4 which receives water from a hose or other connection (not shown) via an inlet line 5 in the handle 3.
  • the water inlet 4 opens into a receiving chamber 6 in the shower head 1, which is followed by a normal jet outlet 7 arranged approximately in the center of the shower head 1.
  • This normal jet outlet 7 is followed by a usual turbulator 8.
  • the normal jet outlet 7 concentrically surrounds a shower outlet 9 with a large number of small shower holes 10, which can also be seen in FIG. 1. 1 makes it clear that this shower head 1 can be switched over from operation with normal jet 11 to operation with shower jet 12.
  • a changeover valve 13 is used for this changeover, which can again be clearly seen in FIG. 2.
  • the changeover valve 13 In a normal position of the normal jet outlet 7, the changeover valve 13 connects to the water inlet 4 and separates the shower outlet 9 from the water inlet 4. This position is also shown in FIG. 2. In a shower position, however, the changeover valve 13 connects the shower spout 9 to the water inlet 4 and separates the normal jet outlet 7.
  • a pushbutton 14 designed as a moisture-proof seal on the top of the shower head 1 is used to actuate the change-over valve 13 and, against the spring force of a spring element 15, is able to lower a valve body 16 in the axial direction when one presses this pushbutton 14.
  • the valve body 16 is in the exemplary embodiment shown in FIG. 2, ie in the normal position, in sealing contact with an upper valve seat 17, so that there is a direct connection between the receiving chamber 6 and the normal jet outlet 7. If you press the push button 14, the valve body 16 is opposed the effect of the spring element 15 pressed down, thereby lifted from the valve seat 17 and brought sealingly to the valve seat 18.
  • the valve body 16 is seated annularly on a piston rod 19, which can be axially displaced by the push button 14.
  • this is only one possible exemplary embodiment for such a changeover valve 13.
  • the changeover valve 13 is in the shower position, in which the receiving chamber 6 is connected directly to a shower chamber 20, which in turn is connected to the shower spout 9.
  • bypass line 21 is integrated in detail in the changeover valve 13.
  • the bypass line 21 can be arranged to a certain extent parallel to the changeover valve 13.
  • the bypass line 21 is arranged in the valve body 16 of the changeover valve 13. This is shown in dashed lines here.
  • This integrated design has the advantage that one the construction of the known shower head 1 as such can be left completely unchanged and only has to replace the valve body 16 in order to arrive at the shower head 1 according to the invention.
  • the valve body 16 of the shower head 1 according to the invention in the exemplary embodiment shown here is, in a manner known per se, a seat valve body which can be displaced in the axial direction.
  • the bypass line 21 is designed as a central, axial channel in the valve body 16.
  • the design here is such that the valve body 16 is arranged on a piston rod 19 having the central axial channel and the piston rod 19 is open at the end at the end facing the normal spray outlet 7 and on the side facing the shower outlet 9 a side inlet opening 22 for has the channel forming the bypass line 21 or part of the bypass line.
  • the teaching of the invention includes the measure to design the flow resistance of the bypass line 21 so that the maximum dynamic pressure occurring upstream of the bypass line 21 is less than the burst pressure of an associated low-pressure accumulator.
  • a matching to different burst pressures is achieved in a particularly simple manner in that an insert which limits the effective flow resistance is interchangeably inserted in the bypass line.
  • bypass line 21 is always open, so that the aforementioned slight leakage current can occur.
  • a more complicated measure which, however, certainly precludes this leakage current when shower holes 10 are not clogged, is to arrange a pressure-dependent opening valve in the bypass line 21. This is not shown here.
