Description
Technical field
The present invention relates to a kind of hand shower with gondola water faucet.
Background technology
This gondola water faucet is used for producing dissimilar water jet.Can be selected by shower head capable rotating head user, whether water jet such as should be fierce or soft or whether should adjust pulse massage jet.
DE 10 2,007 002 894 B3 discloses a kind of such gondola water faucet, wherein, from the outward flange of gondola water faucet, radial water input unit is set, its advantage is, frame mode flat especially can be realized, because moisture is joined without the need to being undertaken by nozzle above chamber in multiple layer stacked up and down again.On the contrary, water directly flows to each subregion from excircle.
But show, ingoing stream radial under the pressure condition that family expenses water supply network is common can cause flow velocity in water inlet region too high.Therefore each nozzle member near water inlet plays Venturi nozzle effect, that is from environment, sucks air there, instead of discharges water.
If use pressure reducer in water-supply-pipe, although this effect can be weakened, the hydraulic pressure in other region away from water inlet of these subregions also may be made may to be not enough to supply high flow to nozzle member or be not enough to whole area forms unified jet graphics.

At this, the sidewall of flow channel has multiple narrow port or reduces on its height, makes to form gap over there over there and/or towards lid towards bottom.
When hose element or rigid pipe element are used as flow channel, overfall is made up of the breach in hose surface or pipe surface.
Be called as the port of overfall or the gap on so-called flood-level rim has large flow resistance due to their opening sections little compared with flow channel cross section, significantly reduce thus and cross the flow velocity that they enter into the water of adjacent chamber.
Preferred flow passage constructs as follows, and namely on the cover element of gondola water faucet or on the base plate of the gondola water faucet base member of gondola water faucet, integrally formed two parallel partitions, as flow channel wall, and arrange the recess of lower height at the top edge of partition.When loading onto now and weld, weld especially by supersonic welding or Laser Welding another parts matched of upper gondola water faucet, the region of the projection of partition is connected with the medial surface of lid or bottom, and do not connect at recess place, thus can water outlet at this.Therefore the manufacture of port is very simple.
Port can also be processed from outside by laser etc. the partition wall of flow channel afterwards.
Owing to there is Pressure Drop and therefore flow velocity also reduces between water inlet and the end of subregion, so recess in other words breach can have along additional flow channel the cross section increased gradually, thus the local volume flow making local enter the water in real chamber from flow channel becomes large and along whole arc flow channel sets up roughly the same pressure.
Flow channel medially can be positioned at function division chamber interior in other words, and for this reason, flow channel is separated by two flow channel wall.Also one can be utilized existing gondola water faucet itself to be divided into multiple partition wall with the chamber of corresponding difference in functionality subregion, and only also comprise an additional flow channel wall, this flow channel wall is now provided with overfall or flood-level rim.

Detailed description of the invention
Fig. 1 illustrates gondola water faucet 30, and it mainly comprises gondola water faucet base member 20 and lid 10.In perspective view in figure 1, lid 10 and gondola water faucet base member 20 are separated from each other a little, but position aligns each other.Lid and gondola water faucet base member are connected to each other by welding, thus gondola water faucet 30 is sealed towards the outside, but the partition wall 24,25 between each chamber also can be made to be connected with lid 10 waterproof.
Gondola water faucet base member 20 is divided into multiple chamber 21,22,23 by partition 24,25, and partition 24,25 extends to below lid 10 from the bottom surface 33 being provided with nozzle insert.In this embodiment, each chamber 21,22,23 has different nozzle insert on bottom surface 33, forms different water jets and function divisions different thus thus.
The inflow entrance 26.1,26.2,26.3 of water from the columniform outer peripheral face being positioned at gondola water faucet 30 flows into chamber 21,22,23.Arrange flow channel 27,28 at this, they are each passed through other chamber 21,22 and supply to being positioned at inner chamber 22,23 and attenuating with the form of bottleneck in the present example.
When water flows into the internal chamber 23 of central authorities by inflow entrance 26.1, then flow velocity is directly improved by the tapered portion be formed in the flow channel 27 between partition 24,25 after inflow entrance 26.1.
As shown in Figure 1, the flow channel 27 leading to the chamber 23 of central authorities is very narrow and repeatedly bending.Under the pressure condition that family expenses water supply network is common, pressure and flow velocity are just in time matched to for producing relative fierce water jet by the nozzle be present in chamber 23.
When the interfluent inflow entrance 26.2 of water, then water is arrived in middle annular compartment 22 by flow channel 28, and arrange miniature bubbler there as nozzle, they produce soft jet respectively.For this reason required water is more than the water needed for the jet graphics being used for being formed in the chamber 23 of central authorities.Correspondingly, in flow channel 28 compared with in the flow channel 27 of chamber 23 leading to central authorities, tapered portion is so not remarkable.
Outer chamber 21 occupies the maximum area fraction of bottom surface, because the nozzle of this chamber should discharge jet soft as far as possible.After the bottom surface that nozzle is housed directly starts from inflow entrance 26.3, flow velocity is very high herein, cause according to this flow velocity of Venturi nozzle principle in hitherto known gondola water faucet does not have water to discharge from nozzle in the region closing on inflow entrance 26.3, but surrounding air is sucked by nozzle.
For this purpose, the present invention specifies when causing arranging additional flow channel in problematic chamber in jet graphics because flow velocity is too high at those.

In the length at least partially of flow channel 11, the flow channel wall 12,13 of flow channel is provided with overfall 16 or flood-level rim 12.1, is entered into can making the large big retarding of water be arranged in the other sub-chamber 21.1,21.2 in flow channel 11 side by them.
In the embodiment of the gondola water faucet 30 shown in Fig. 2, the height of flow channel wall 12,13 is slightly less than the free height of chamber 21, thus can form leakage current below flood-level rim 12.1, and its flow velocity be enough to greatly reducing fills sub-chamber 21.1,21.2.
In an illustrated embodiment, in the flow channel wall 12 in outside, several overfall 16 such as stitching shape is also processed.These overfalls can arrange the flow rate for realizing in inflow sub-chamber 21.1,21.2 higher targetedly on location.
Such as can process overfall 16 by laser in flow channel wall 12,13 afterwards.
In the embodiment of the gondola water faucet 30' shown in Fig. 3, basic structure is with according to the gondola water faucet 30 of Fig. 2 always.Difference is only, overfall 16' is with on the lower limb being set in sequence in flow channel wall 12', 13' replaced with the section arriving lower part, produce battlement shape structure thus, its advantage is, each flow channel wall energy, with its regional area stretched out and bottom welding, improves the stability of gondola water faucet downwards thus on the whole.In addition, can locally improve or reduce the flow velocity of the current flowing to sub-chamber 21.1,21.2 targetedly by changing the quantity of " battlement ", length and spacing.
Hand shower 40 complete shown in Fig. 4, hand shower is as known by DE 10 2,007,002 894 B3.
At this, gondola water faucet 20 is rotatably supported in hand shower housing 46.Hand shower housing has the supporting member for receiving gondola water faucet 20 in gondola water faucet region 46, and therefore gondola water faucet can rotate around pivot center 47.In order to this rotation, user catches gondola water faucet 30 on knob 31.
Gondola water faucet region 46 is connected with handle area 45, and by handle area, such as receivability is in the holder for hand shower 40.
Unillustrated pipe is through handle area 45, and this pipe leads on the pipe joint 43 of inflow element 42.The shape in the round and smooth portion of the outer change edge of gondola water faucet 30 copied by overhanging plate 44 and shape guides in locking manner in the portion that exceeds 34 of hook-type.In addition, before each flow export flowed in element 42 directly can be positioned at one of inflow entrance 26.2,26.3 on the outward flange of gondola water faucet 30.Therefore always only that is flowed into by water with the function division that its inflow entrance 26.1,26.2,26.3 is directly opposite with the flow export flowed in element 42.
