Definitions

  • a water fitting is described here which is particularly suitable for use in kitchens. Recently, the hygienic requirements for water fittings have continued to increase. At the same time, there is a need to be able to provide the user/user with several jet types, so that the user has different ways of providing water (for example, different jet hardnesses) at his disposal.
  • a water faucet for example, a hard jet with a high impulse of the exiting water can be used to clean dishes, while another (more gentle) jet can be used to clean vegetables or carry out similar tasks.
  • a shower head for a kitchen water faucet having an outlet for water, which is formed by a plurality of outlet openings, the outlet openings branching off from a ring-shaped channel, with at least one rotating element being arranged in the ring-shaped channel in such a way that it runs along the ring-shaped channel circulates when water emerges from the outlet, with the rotation element briefly covering each individual outlet opening when circulating in the annular channel, so that an inflow of water to the respective outlet opening is interrupted, so that a pulsation of water emerging from the outlet openings of the outlet is caused.
  • At least one deflection surface is arranged on the at least one rotation element, which causes water in the annular channel to be deflected in a circumferential direction along the annular channel in order to generate an impulse which causes a rotational movement of the at least one rotation element in the annular channel supported
  • a pulsating shower jet can be generated by the shower head described.
  • a pulsating shower jet may have considerable improvement potential compared to non-pulsating shower jets with regard to the cleaning effect that can be achieved with it. This is due to the fact that the pulse of the water emerging from the shower head changes regularly due to the pulsation. In this way, it is often possible to achieve improved detachment of contaminants with the help of the water.
  • the pulsation of the exiting water is achieved in that the first rotating element in the ring-shaped channel regularly and repeatedly closes the individual outlet openings of the outlet.
  • the proportion of water emerging from the respective outlet opening of the outlet is briefly interrupted. So a pulsation with simple mechanical means is achieved. In particular, no active activation and deactivation of individual outlet openings is required in order to cause or generate a pulsating jet.
  • the annular channel encircles an outlet end of the shower head 360°.
  • the rotating element can perform a complete orbital movement indefinitely in the annular channel. For this reason, once the production element is accelerated to a desired speed, very little momentum is required to keep the rotary element moving in the annular channel.
  • the outlet openings of the outlet are preferably arranged in a uniformly distributed manner along the annular channel. There are preferably between 10 and 100 outlet openings along the annular channel (for example between 15 and 35 outlet openings in a particularly preferred embodiment, for example exactly 20 outlet openings). The exact number of outlet openings is not important for the functioning of the shower head described here.
  • outlet openings are always open or out of a fixed number of outlet openings (e.g. 20 outlet openings, for a maximum of three at least two outlet openings are always closed.
  • the total amount of water emerging from the shower jet is therefore continuous. This has many Advantages because it avoids, for example, pressure fluctuations within the shower head and in a water supply supplying the shower head.
  • An annular channel in the shower head is preferably formed by a web insert which forms the web (annular channel) as a half-shell.
  • An outlet cap which forms the other half-shell of the track (the ring-shaped channel), is preferably placed on this track insert.
  • the outlet cap is preferably removable.
  • At least one deflection is implemented at an inlet for water in the annular channel, which causes water in the annular channel to be deflected in a circumferential direction along the annular channel in order to generate an impulse which causes a rotational movement of the at least supports a rotating element in the annular channel.
  • the inlet is preferably an inlet opening at which water provided with the shower head enters the annular channel before it then exits again at the outlet openings of the outlet from the annular channel with the spray pattern.
  • a deflection of water when entering the annular channel at the inlet means in particular that the water does not enter the annular channel in a perpendicular direction (perpendicular here in particular to a plane formed or defined by the annular channel).
  • the water particularly preferably enters the ring-shaped channel in such a way that a direction of the entering water has at least one component along a circumferential direction of the ring-shaped channel. This can be achieved, for example, by means of inclined occasions, the direction of which has a component in the direction of the circumferential direction.
  • the at least one rotation element is a sphere.
  • a sphere as a rotating element has many advantages, because a sphere cannot stick as easily in the ring-shaped channel as a more complex component. In addition, with a sphere, manufacturing tolerances must be observed particularly well.
  • the at least one rotating element is a carriage element that is adapted to the curvature of the annular channel.
  • a carriage element as a mutation element has the advantage that it has a particularly precise guidance in the ring-shaped channel. Due to the shape of the carriage element, the cross section of the ring-shaped channel is preferably completely filled over a certain angular segment of the ring-shaped channel. A complete closure of outlet openings of the outlet can thus be achieved.
  • the at least one rotating element is a ring element which is arranged rotatably in the ring-shaped channel.
  • a rotating element designed as a ring element has particular advantages because a particularly high level of control of the movement of the rotating element is possible.
  • the ring element preferably fills the ring-shaped channel by 360° on all sides.
  • a special covering area is preferably provided on the ring element, which is only provided in a specific angular segment of the ring element and which is set up to cover outlet openings of the outlet.
  • the update area or the angle segment covered by the covered area has a size set exactly for the desired pulsation. In this way it can be achieved that exactly the desired number of outlet openings of the outlet is covered.
  • the rotating element designed as a ring element preferably has deflection surfaces that deflect the water flow in the cause annular channel.
  • deflection surfaces are designed on the rotating element, it may no longer be necessary to additionally provide deflections at inlets for water into the annular channel. With such deflection surfaces on the rotary element, even when water flows into the annular channel in the vertical direction, an impulse of the water can be achieved, which supports a revolving movement of the rotary element.
  • the shower head has a further outlet, which is arranged in a central area surrounded by the outlet with the outlet openings and with which a mousseur jet can be provided.
  • a shower head having a switching means with which, optionally, a first water-conducting connection from a water inlet to the outlet with the annular channel and the outlet openings or a second water-conducting connection from the water inlet to the further outlet within the annular channel to provide a mousseur -Beam can be produced.
  • the shower head preferably has a switch with which the switching means can be switched.
  • FIG. 1 shows a shower head 1 as described, which has a water inlet 17 to which, for example, a hose (not shown here) can be connected in order to supply the shower head with water.
  • the water travels along a first water-conducting connection 16 from the water inlet 17 to an outlet 2, at which the water is made available to the user/user in the form of a spray pattern.
  • the outlet 2 is formed by a plurality of outlet channels 3, from which individual jets emerge.
  • the spray pattern provided at the outlet 2 can also be referred to as a "spray jet".
  • the outlet channels 3 of the outlet 2 branch off from an annular channel 4 .
  • the annular channel 4 forms a path in which at least one rotating element 5 can rotate. Means are provided which support a revolving movement of the rotating element 5 in the ring-shaped channel 4 and which have already been described above and which are described in more detail below in connection with the other figures.
  • a further outlet 13 which is arranged in a central region 14 within the annular channel 4 or surrounded by the annular channel 4.
  • This further outlet 13 is supplied with water via a second water-conducting connection 18 from the water inlet 17 to the further outlet 13 .
  • water is provided with a mousseur jet.
  • the shower head 1 preferably has a switching means 15 designed as a valve with which the first water-conducting connection 16 to the outlet 2 or the second water-conducting connection 18 to the further outlet 13 can be opened.
  • the switching means 15 is preferably actuated via a switch 22 .
  • the 2 shows an outlet cap 20 of a shower head 1 described 3 shows a track insert 21 of a shower head 1 described.
  • the outlet cap 20 and the track insert 21 together form the annular channel 4 in which the rotating element 5 (not shown here) can rotate in the circumferential direction 7 .
  • Both the outlet cap 20 and the web insert 21 are also in 1 shown.
  • the actual outlet 2 is formed by the outlet openings 3 in the outlet cap 20 . Also visible is the (here free) central area 14 in which in the shower head 1 according to FIG 1 , then the further outlet 13 for the mousseur jet is arranged. In 3 inlets 8 through which water can enter annular channel 4 can be seen.
  • FIG. 4 a cross-section according to the section AA shown in Fig. 3d through the track insert is shown.
  • An inlet 8 is shown here as an example. It can be seen that the inlet 8 is shifted by a deflection 9 in relation to a vertical direction 24 (normal to the circumferential direction 7). As a result, water is directed into the annular channel 4 in such a way that a flow and an impulse are created there, which drives the rotating body 5 and causes the rotating body 5 to rotate, so that the outlet openings 3 according to FIG 2 are covered for a short time so that a pulsating jet is created.
  • FIG. 5 shows an alternative track use 21 too 4 in a top view.
  • This web insert 21 has inlets 8 with a plurality of deflection surfaces 6 to induce flow in the annular channel 4.
  • FIGS. 6, 7 and 8 show different types of rotating elements 5, which can rotate in the annular channel 4 of the shower head 1.
  • a sphere 10 is shown forming a first type of rotation element 5 .
  • a carriage element 11 is shown, which forms a second type of rotary element 5 and which has a curvature 23 adapted to the shape of the annular channel 4 .
  • a ring element 12 is shown as a rotary element 5 according to a third type.
  • Such a ring element 12 preferably also has a curvature adapted to the ring-shaped channel 4 .
  • the ring element 12 as the rotating element 5 also has a cover area 19 here, which always covers the individual outlet openings 3 for a short time interval when the ring element 12 rotates, so that the supply of water to these outlet openings 3 is interrupted, so that a Outlet 2 provided pulsating jet adjusts.
