Definitions

  • the invention relates to a shower head with a housing and a jet exit surface from the housing.
  • the beam exit surface has a multiplicity of exit openings.
  • Such showers have long been known in a variety of forms and in themselves have numerous functional options.
  • the invention has for its object to provide an initially mentioned shower with functional options which are not yet known in the prior art and in particular enable advantageous use.
  • the shower contains a housing which is closed off to the user side by a spray disc.
  • This jet disc contains a large number of jet outlet openings, which can be specially designed by certain arrangements.
  • the shower contains a flat, large housing.
  • the ventilation device can, for example, be designed in such a way that it introduces the air through the jet outlet disk into the housing, for example directly in the middle in the preferably plane jet disk.
  • the shower according to the invention can contain a jet-forming means for forming several individual water jets already within the housing. The individual water jets are not only formed when you leave the shower head. In this way it is possible to carry out certain processes with the water jets within the housing.
  • the aeration device can be designed such that it aerates the water in front of the jet-forming agent.
  • the jet-forming agent then serves to form individual aerated jets from a aerated jet, which are then distributed within the shower housing, for example over an area which has a large diameter compared to the water inlet, for example a diameter in the range of 10 to 20 times larger ,
  • the jet-forming means and / or the ventilation device is designed such that the individual jets already formed are ventilated jointly and / or separately. This makes it possible not to have to consider the later aeration when forming the water jets.
  • the shower head can have guide means in order to guide the aerated water jets to the jet outlet openings of the entire jet disk, preferably uniformly, but also non-uniformly as desired.
  • the guide means can be arranged at a wide variety of locations in the shower, for example in the distribution chamber which is formed directly behind the spray disc.
  • the guide means can also be arranged where the jets formed are aerated or where the aerated jets are formed.
  • the guide means and / or the ventilation device can be designed such that they produce a swirling of the aerated jets.
  • This is successfully installed, among other things, is suitable for increasing the duration of the rays within the shower housing, in order in this way to achieve longer and / or more intensive contact with the devices present in the shower housing.
  • the ventilation device can be designed in such a way that it generates an air flow that strikes the water flow perpendicularly, wherein, as already mentioned, it can strike individual water jets that have already been formed.
  • each air jet is assigned to a water jet that it encounters.
  • a complete or only partial separation of air flows and water flows can be carried out in the housing. This makes it possible to aerate the individual water jets to different degrees or even at different locations.
  • the jet-forming means can have, for example, a perforated disk which is arranged transversely to the water flow. A water jet is then generated through each hole. As already mentioned, these water jets can either be completely separated or only partially separated, so that different individual flow threads are formed within a common water volume.
  • the ventilation device can have a central sleeve or hub, through the interior of which the air reaches the interior of the housing from the outside.
  • the hub can, for example, have a smooth end face, which forms a flat annular space with a corresponding counter surface, through which the air flow is directed onto the water.
  • this front end has radial air ducts, for example grooves, which lead to a separation of the air flow.
  • the end of the radial air ducts is aligned with the openings of the perforated disk.
  • the alignment may be such that the center line of the grooves is aimed at the center of the openings.
  • there is a tangential alignment so that the center line of the grooves runs eccentrically to tangentially to the openings of the perforated disk.
  • the air ducts can run exactly radially or slightly obliquely.
  • the hub at the inner end of which the air flows essentially radially in a plane to the longitudinal axis, can also contain guides for the ventilated jets on its outer lateral surface, which lies in a cylindrical surface. These guides can be the grooves that are aligned with the holes in the perforated disc are. These guides are used to allow the aerated jets to separate during their further travel within the shower housing, i.e. to delay or hinder their reunification.
  • the grooves can run primarily in the axial direction, but they can also run slightly obliquely, for example in the manner of a steep thread.
  • a deflection can take place by means of a corresponding conical design of the outside of the hub. This deflection can also take place gradually, for example in that the outside of the hub merges into a radial plane in a curved shape. This curved shape or the gradual transition or the deflection can also take place regardless of the presence of axial water channels.
  • the deflecting means can also have individual channels which can then run in a straight line, linearly, obliquely or curvedly.
  • Guide means which can be aligned with the direction of the deflecting means, can be arranged inside the housing of the shower, ie behind the jet disc. This is to achieve a good distribution of the aerated water jets over the entire surface of the jet disc.
  • the guide means can be present, for example, on the back of the housing or also on an insert in the housing.
  • a shower head can be in addition to a housing and a jet outlet surface with outlet openings and a subdivision have a changeover device in at least two areas.
  • the water supply can be changed between a first area and a second area.
  • water is provided in the shower, which ensures the water supply to the shower.
  • An air supply device is provided for aeration of the water jets emerging from the shower. The water supply is aerated by means of the air supply device, namely between the water inlet and the jet outlet surface. The air supply device can be activated and deactivated, so it can be switched over.
  • the changeover device and the air supply device are coupled to one another such that when the changeover device is actuated, the air supply is switched from activated to deactivated or from deactivated to activated.
  • the air supply device changes its activation state when switching from the first to the second area.
  • a double function is provided when the changeover device is actuated. It is therefore also clear here that the direction of actuation could also be the other way round, that is to say a change from one area to the other when the air supply device is activated or deactivated.
  • the first region is a partial region of the beam exit surface, it being possible, for example, to be a central region.
  • the entire jet exit area is provided as the second area.
  • the air supply can be activated when the changeover device is placed on the second area or on the entire steel outlet surface. This has the advantage that the air supply or the ventilation tion of the water jets a voluminous appearing water outlet can be created, which is particularly advantageous in the case of a larger area with the increased number of outlet openings.
  • the changeover device can advantageously be operated by hand. To do this, either a button or slider or the like can be pressed in. An entire and in particular larger housing part can advantageously be moved relative to another housing part or the rest of the housing.
  • the two areas or all areas can be connected to the water inlet for the water supply via a distributor chamber.
  • the distributor chamber can advantageously extend over the surface of all areas or the rear of the beam exit surface. This ensures good water supply for all areas and all jet outlet openings on the jet outlet surface.
  • the changeover device can be designed such that it is arranged and acts in the distribution chamber. When adjusting to the first area, it can limit the distribution chamber to the area corresponding to the first area. When changing to another area or the second area, the boundary of the distributor chamber is adapted to the area of this further area. If the entire jet exit surface is switched over, the boundary of the distributor chamber can be removed so that it extends over the entire jet exit area.
  • the changeover device can have a closure, which can particularly preferably be designed to delimit the distribution chamber.
  • the distribution chamber can easily be limited by the fact that the closure can be placed on the back of the beam exit surface. This system is advantageously sealing.
  • the distribution chamber is particularly advantageously delimited by a wall as a closure. The area within this wall advantageously forms the Part of the distribution chamber that corresponds to the selected area of the jet exit surface.
  • a trained seal can be provided to improve the tightness of the system.
  • a lip seal is suitable for this, for example. It can have an attachment direction to a sealing seat, which runs in the direction of the water pressure in the limited distribution chamber. A water pressure that arises also contributes to the sealing effect.
  • One way of designing a beam exit surface is to choose an elastic material.
  • This is an elastomer, for example, which can be rubber-like.
  • a wall or a closure can be placed on the back of such a jet disc in order to achieve a sealing effect.
  • a previously mentioned seal can advantageously be molded on the back of the jet disc in a protruding form. So you can save a separate seal.
  • a water supply is advantageously carried out centrally in the shower, at least in the area just before the distribution chamber. A distribution as uniform as possible across the beam exit surface is thus possible.
  • a central air supply device to the shower or to the jet outlet surface is also advantageous. Water is advantageously supplied from the rear of the jet outlet surface or the shower.
  • An air supply device can run through a central opening in the jet outlet surface, that is to say from the front into the shower housing.
  • a channel can be provided for the air supply, which can not only run through the jet exit surface, but can even be connected to it or fastened in its area. Furthermore, it is possible to connect the changeover device to the water inlet or to attach it to it. To change and activate the shower head at an embodiment of the invention, the jet exit surface are moved relative to the water inlet. A closer at the water inlet can then close or open the duct for the air supply. At the same time, for example, a wall of the changeover device would limit the distribution chamber.
  • the air supply can run through the front of the shower, namely through the jet outlet surface.
  • the air exits the channel of the air supply with a direction transverse to the water supply or the water inlet.
  • air is sucked in and the water is swirled with the air.
  • the air can be distributed into the water supply.
  • the water supply can have a multiplicity of openings which can be distributed in a ring around a central axis.
  • the openings are advantageously elongated holes, among other things to accelerate the individual water jets.
  • the air from the air supply can come in directly behind the openings, for example due to the aforementioned venturi effect. This ensures that air and water are mixed well.
  • swirling devices in the direction of the water flow behind the location of the air inlet.
  • the mixture of water and entrained air impinges on these swirling devices, which may have the shape of several stages, for example, and is swirled and mixed even more strongly.
  • Swirling devices of this type are advantageously distributed around a central axis of the shower housing or around a channel for the air supply. For example, they can be molded onto the outer sides of the channel walls. This is particularly useful if the channel for the , - -

Furthermore, the tube extension 17 has grooves 19 which run obliquely in the manner of a thread. The projections 22 engage in these grooves. Thus, the casing shell 12 moves relative to the base 13 when rotating, as is clear from the comparison between FIGS. 1 and 2. Instead of such a thread-like design, short grooves and projections could also be used to push and thus move the housing shell 12 relative to the base 13 directly along the central axis for adjustment.

Abstract

Selon un exemple de mode de réalisation, une douche est pourvue d'un corps et d'une surface de sortie de jets. D'une part, la douche, dont la surface de sortie de jets est divisée en zones, comprend un dispositif de réglage permettant de passer d'une alimentation en eau de certaines desdites zones à une alimentation en eau de toutes les zones, la sortie des jets pouvant se faire dans une zone centrale plus petite et dans une zone entourant cette dernière. D'autre part, la douche est pourvue d'un dispositif d'alimentation en air servant à introduire de l'air dans les jets d'eau. Ce dispositif d'alimentation en air est actionné simultanément lors du réglage permettant de sélectionner les différentes zones.
