Definitions

• the invention relates to a hand shower with a shower head, which has at least one inner chamber with a plurality of nozzle openings in the bottom and which has at least one inlet opening per inner chamber on the outer circumference, which Zulauf ⁇ réelle each by means of a feed element, which is integrated into the hand shower housing, can be flowed ,
• Such shower heads are used to produce different types of water jets. By turning the shower head, the user can choose whether the water jet is e.g. hard or soft or whether a pulsating massage jet should be set.
• the object of the invention is thus to improve a shower head of the type mentioned so that the suction of air due to excessive local flow velocities is avoided and a uniform water outlet is achieved at all similar nozzle elements within a chamber.
• the chamber can be flowed on via an additional flow channel, which has at least one overflow opening and / or an overflow edge, through which overflow or overflow edge of the flow channel is connected to the chamber.
• the flow channel is arranged in at least one inner chamber of the shower head and separated, for example by at least one additional side wall of the chamber. He can also by a inserted into the chamber pipe or Hose element be formed.
• the flow channel preferably extends from the radial water inlet on the cylindrical lateral surface to the rear regions of the annular zone region.
• the side walls of the flow channel narrow openings or are reduced in height so that forms a slot towards the bottom and / or the lid.
• the overflow openings are formed by recesses on the hose or pipe jacket.
• overflow openings or the slots at the so-called overflow edges form a large flow resistance due to their small opening cross-section in relation to the flow channel cross-section, so that the flow velocity of the water which enters into the adjacent chamber above is substantially reduced.
• the flow channel is formed by the fact that either parallel to the cover element or to the bottom plate in the shower head element of the shower head two parallel webs are formed as flow channel walls and that at the upper edge of the webs recesses of low height are provided.
• the associated other part of the shower head is placed and welded, in particular by ultrasonic or laser beam welding, the upstanding areas of the web are connected to the inside of the lid or the floor, while in the recesses no connection takes place, so that here a Was- This is possible.
• the production of the breakthroughs is so very simple.
• the recesses or recesses along the additional flow channel can have an increasingly larger cross section, so that the partial volume flow of the water which flows locally out of the Flow channel over enters the actual chamber, becomes larger and builds up along the entire arcuate flow channel in about the same pressure.
• the flow channel can be placed centrally within a functional zone or a chamber, for which purpose it is separated via two flow channel walls. It is also possible, an already existing partition wall, which divides the shower head into several chambers with correspondingly different functional zones, and only to use an additional flow channel wall, which is then provided with the overflow or the overflow edges.

• Lid 10 and effervescent element 20 are slightly raised in the perspective view of Figure 1, but in the correct position to each other, shown. They are connected by welding together to seal the shower head 30 to the outside, but also to waterproof the partition walls 24, 25 between the individual chambers to connect to the lid 10.

• Each of the chambers 21, 22, 23 has in this embodiment at the bottom surface 33 different nozzle inserts, so that there are different water jets and thus different functional zones.

• the flow channel 27 leading into the central chamber 23 is very narrow and moreover angled several times.
• pressure conditions in the domestic water network pressure and flow rate are precisely suitable to produce relatively hard water jets with the existing in the chamber 23 nozzles.
• the water passes via the flow channel 28 into the central, annular chamber 22, where mini-aerators are provided as nozzles, which each generate a soft jet.
• mini-aerators are provided as nozzles, which each generate a soft jet.
• more water is needed than for the spray pattern generated in the central chamber 23. Accordingly, the taper in the flow channel 28 is less pronounced than in the leading to the central chamber 23 flow channel 27th
• the outer chamber 21 has the largest surface portion of the bottom surface, as the softest rays are to be delivered via the nozzles in this chamber.
• the equipped with nozzles bottom surface begins immediately behind the inlet opening 26.3, where then a very high flow rate is applied, which leads to the previously known shower head to the principle of a Ventu- ri-nozzle in one of the inlet opening 26.3 adjacent area not water is discharged from the nozzles, but ambient air is sucked from the nozzles.

• the flow channel walls 12, 13, a height which is slightly smaller than the clear height in the chamber 21, so that below the overflow edges 12.1 can form a leakage flow which is sufficient to to fill the sub-chambers 21.1, 21.2 with greatly reduced flow velocity.
• slot-shaped overflow openings 16 are introduced into the outer flow channel wall 12. These can be provided in order to be able to specifically effect higher flow rates into the subcompartments 21.1, 21 at certain points.
• the overflow openings 16 can be introduced later into the flow channel walls 12, 13, for example by means of lasers.
• the basic structure is identical to the shower head 30 according to FIG.
• This has the advantage that the flow channel walls can be welded with their further downwardly projecting portions with the ground, which increases the overall stability of the showerhead.
