Definitions

  • the invention relates to a structural unit as part of a shower device according to the preamble of claim 1 and a shower device according to the preamble of claim 15.
  • a shower head is known from the prior art, for example from FM Mattsson Mora Group AB, Sweden, which is sold under the name "Mora Tronic Compact", with cold and warm water being mixed directly in this shower head.
  • the shower head itself is also equipped with an integrated valve for adjusting the volume flow.
  • the object of the invention is to propose a structural unit which is as compact as possible as a component of a shower device and which enables improved comfort and improved performance.
  • the structural unit according to the invention serves as part of a shower device. Depending on the design variant, it can be partially embedded in a wall so that it is aligned flush with the wall surface, or it can be placed on a wall.
  • the unit includes the water outlet, for example in the form of a shower head.
  • the water outlet can accordingly emit one or more water jets with which people / users can wash themselves.
  • the water outlet is usually fixed or variable at a sufficient height above the floor or a shower tray, so that the water exiting the water outlet can completely wet a person of normal size when showering.
  • the water outlet can optionally, depending on the variant, be designed to be adjustable so that different exit options for the water jets (rain shower, many or a few, fine or thick jets, etc.) can be set.
  • a mixing and control device is provided with which not only the volume flow, but also the water temperature can be adjusted.
  • the mixing and control device accordingly comprises a first and a second feed line for supplying the warm or cold water and for mixing the warm and cold water.
  • the actual mixing process of the water quantities at different temperatures takes place in the so-called mixing chamber.
  • the mixing chamber can be designed, for example, in such a way that a flow arises in it, which ensures that the warm and cold water supplied can mix as homogeneously as possible.
  • a flow element in the mixing chamber can also be used for this purpose be arranged, which ensures good mixing and, for example, generates a partly turbulent flow to improve the shower mixture.
  • the mixing chamber is fluidly connected to the water outlet so that the water outlet can be fed with temperature-controlled mixed water.
  • the structural unit according to the invention is initially characterized in particular by a particular compactness, since the mixing and control device and the water outlet are completely integrated in a first structural section.
  • the mixing chamber and water outlet are therefore arranged very close to one another so that short distances can be used for the waterway.
  • better performance can be achieved with the structural unit according to the invention because, among other things, the temperature adapts more quickly to the new mixture, because the distance or the volume between the mixing chamber and the water outlet can be significantly shorter according to the invention.
  • the mixing and control device can, for example, be covered from the outside by a housing or a housing section or housed therein, while only the water outlet then lies outside the housing.
  • the first construction section can, however, be a compact section in a specific area or at a specific height of the shower device.
  • the structural unit according to the invention is characterized in that not only two valve devices, namely a first valve device for controlling the flow from the first feed line and a second valve device for Control of the flow from the second feed line are provided, both of which open into the mixing chamber, but also in that both valve devices are each equipped with an actuator for opening and closing the respective valve device.
  • the actuators each include a separate electric motor, for example.
  • the actuators are designed in such a way that they can be activated by a control or monitoring unit.
  • the control or monitoring unit can be operated or controlled by an operating device (such as a rotary knob, a button, a lever or the like) and / or regulate the temperature or the volume flow (flow meter) by a sensor (temperature sensor).
  • the water temperature and, if necessary, the volume flow can also be influenced by any computer using an app and / or a facility management system (eg predetermined, individual temperature settings).
  • the volume flow and the water temperature can then be set via an operating device.
  • the control unit does not have to be integrated into the first construction phase. It is sufficient to connect the actuators to the operating device via an electrical control line or, if necessary, also wirelessly.
  • Such a compact arrangement is also characterized by a special hygiene, because after the water flow has been switched off, only a small amount of water, if at all, remains between the mixing chamber and the water outlet, thus minimizing the risk of contamination and bacteria formation.
  • both cold and hot water supply lines each have their own control valve in the form of the valve device, not only the volume flow, but also the temperature of the water can be set during operation by the user who is showering.
  • the invention also differs greatly from conventional shower devices from the prior art, since although a mixture of warm and cold water is generally provided in the shower head or in the area of a water outlet, a temperature setting that can be changed during operation and is therefore comfortable is possible with conventional shower heads not possible from the prior art. Rather, a fixed pre-setting on the valves on the hot or cold water inlet has previously had to be made using an adjusting screw. During operation, such a conventional shower head or the housing surrounding it would have to be opened, which is no longer necessary according to the invention.
  • the operating device is able to jointly set temperature and volume flow via its own control unit. So if the temperature is to be changed with a constant volume flow, one of the valve devices must be opened more in order to adapt the temperature accordingly, while the other valve device is closed more tightly in order to maintain the volume flow.
  • the distance over which the mixing chamber is connected to the water outlet in a fluid-conducting manner is at most 150 mm. Smaller distances of at most 120 mm or even at most 100 mm are even more preferred.
  • the volume that is present as a fluid-conducting connection between the mixing chamber and the water outlet can be at most as large as the volume of the mixing chamber.
  • the first construction phase can have a small volume, such as less than 1-2 liters.
  • the distances to essential components of the first construction phase can be kept very short. Accordingly, the compactness, which is immediately recognizable from the outside, is once again underlined.
  • the operating device is integrated in a second construction section that is different from the first construction section or with the first Construction stage does not overlap.
  • This option proves to be particularly advantageous when the actual shower head is to be made as small and compact as possible and, moreover, is to be attached at a greater height at the same time. In such an embodiment it is not a hand shower because the user can hold the hand shower himself by a handle while he is showering. Instead, in such a permanently installed shower, the water jets come from a certain height, which is usually selected so that the water jets can completely hit the majority of people from above.
  • the mixing chamber were arranged directly on the operating device and mechanically coupled to it, a relatively large water path and consequently a relatively large volume would be found between the mixing chamber and the water outlet.
  • This fact is structurally due to the fact that the operating unit must be easily accessible for the user, while the actual water outlet must be installed at such a height that people are generally to be hit by the water jets from above / on the head. The water outlet must therefore be installed at an appropriate height.
  • the advantage is particularly used that the mixing chamber is arranged in a first structural section that differs from that of the operating device.
  • connection from the operating device to the mixing and control device is made via an electrical line or, if necessary, also wirelessly, ie distances of typically 1 m to 1.50 m, possibly even more, can in principle can be bridged without difficulty.
  • a cable between the operating device and the first construction section requires very little installation space. This applies in particular in the event that a wireless connection is provided.
  • the operating device can thus be mechanically decoupled from the mixing and control device or from the actuators so that the operating device does not, for example, directly mechanically operate the valve device by exerting a force on the valve tappet via an axis, for example. It is precisely through this measure that it is possible to bridge such a distance between the operating device and the actual mixing and control device without further ado.
  • This advantage can basically also be used with a hand shower, in which the actual shower head is held in the hand, while the volume and temperature setting can be adjusted on a fitting on the wall and is carried out in a mixing chamber in the wall.
  • only little installation space, if at all, advantageously has to be made available on the route between the operating device and the water outlet.
  • a structural unit according to the invention is characterized in that it can also be retrofitted particularly well in existing shower systems without having to create additional space.
  • the water outlet can be level with the mixing chamber be arranged so that a compact construction section is created.
  • the two valve devices can also be arranged at the level of the mixing chamber or the water outlet.
  • the water outlet can usually be made small and compact and sit directly on the wall or on the housing so that it is not arranged spaced apart from the wall by a further pipe section; as a result, the volume in which water can remain when it is switched off is rather small.
  • the close proximity of the mixing and control device or the two valve devices to the water outlet makes it possible for the volume on the path of the water between the mixing chamber and the water outlet to be as small as possible.
  • the conduction path of the water in the first construction section can form a flow path which has at least three flow path sections, of which the first flow path section runs through one of the valve devices, a second leads through the mixing chamber and a third leads from the mixing chamber in the direction of the water outlet , wherein the first, the second and the third directly adjoin one another and wherein the first and the third flow path section each run essentially completely perpendicular to the second flow section.
  • the first, second and third flow path sections together preferably form a U-shaped conduit path. This enables the arrangement of the two valve devices together with the mixing chamber and the possibly remaining path to the water outlet to be designed in a highly compressed manner and in one compact design is made possible within the first construction phase.
  • the components can be arranged in such a way that a functional unit that is as space-saving as possible is created.
  • the first flow path sections of the first or second valve device can each be arranged parallel or skewed to one another or the first flow path section of the first or second valve device can each be aligned parallel or skewed to the third flow path section.
  • a skewed arrangement provides greater flexibility in the positioning of the valve devices within the first construction section, in particular in the part of the first construction section which is contained in a housing, e.g. in the wall.
  • both valve devices can be arranged at the level of the mixing chamber in order to ensure a particularly compact structural unit.
  • the line path described can also branch off by 90 ° within the respective valve devices. Because of their length, the valve devices can be oriented horizontally, for example.
  • the feed lines can then open vertically into the valve devices to save space.
  • the valve devices can then turn perpendicular to the main flow direction in the Open into the mixing chamber.
  • a fourth flow path section can also adjoin the third and optionally run essentially perpendicular to the third flow path section.
  • a temperature sensor can be provided in or after the mixing chamber in order to check whether the amount of water flowing out of the water outlet has a predetermined temperature.
  • the temperature sensor can be connected to the operating device, with which the water temperature is also set, so that the target temperature of the water can be compared directly with the temperature measured by the sensor.
  • a control device for activating or regulating the valve devices can generally be arranged in the operating device, in the area of the sensor, etc.
  • first and second valve devices can each have a proportional valve. This basically makes the setting easier.
  • Embodiments of the proposed structural unit can be used, in particular flush, in a wall as a shower element or placed or mounted on the wall as a shower panel.
  • such embodiments of the invention are distinguished by the fact that a design with a small depth is possible due to the compactness, so that little space is required.
  • the compactness also advantageously enables it to be used as a hand shower element.
  • FIG 1 shows the first construction phase I of a structural unit 1 according to the invention as part of a shower device.
  • the first construction phase I itself can in principle also form its own structural unit.
  • This construction section I comprises a water outlet 2 in the form of a shower head, which is connected to a mixing and control unit MC by a housing 3 or a housing cover 3.
  • the mixing and control unit MC as in Figure 1 shown, but is located behind the cover of the housing 3.
  • the water outlet 2 (and possibly the housing 3) is actually visible. Point at the water outlet 2 the nozzles 4 downwards, so that the water is dispensed through the water outlet 2 for showering downwards towards the user.
  • Figure 1 to see a mixing chamber 5, which has a cylindrical shape.
  • a temperature sensor 7 is arranged within this fluid-conducting connection 6.
  • Figure 2 shows a section which runs through the mixing chamber 5 and the first and second valve devices 8, 9.
  • the first valve device 8 regulates the inflow of warm water
  • the second valve device 9 regulates the inflow of cold water.
  • Both valve devices 8, 9 are directly connected to the mixing chamber 5.
  • the mixing chamber itself 5 can in turn be provided with a flow element in its interior, so that the inflowing cold and warm water is mixed more effectively.
  • the mixing chamber 5 opens into the connection 6, which finally leads to the water outlet 2.
  • the sectional drawings in Figure 2 show the first construction phase 1 in a front view, so that the water outlet is in Figure 2 located in front of the drawing plane.
  • the temperature sensor 7, which determines the temperature of the mixed water formed in the mixing chamber 5, is in turn arranged in the fluid-conducting connection 6.
  • the path of the hot water H and des is also shown cold water C, which finally open into the mixing chamber 5 via the valve devices 8, 9 in order to form the mixed water of a predetermined temperature there.
  • the valve devices 8, 9 each have a valve seat 10, 11 and a matching tappet 12, 13, which seals against the respective valve seats 10, 11 in the closed state.
  • the plungers 12, 13 are moved along the longitudinal direction of the valves 8, 9, with the help of electric motors 14, 15.
  • These units from the plunger 10, 11 to the electric motor 14, 15 form the actuators 16, 17 and C lead from below into the two valve devices 8, 9 (cf. Figure 2 ) and bend 90 ° in the area of the tappets 12, 13.
  • the adjoining, second flow path section M leads through the mixing chamber 5 again perpendicular to the outflow direction from the valve devices 8, 9.
  • FIG 3 again another section is perpendicular to that in Figure 2 shown section.
  • the mixing and control device MC is located behind the cover of the housing 3.
  • the first and second valve devices 8, 9 are arranged offset from one another in the lower region.
  • the feed lines H and C for hot and cold water open from below into the two valve devices 8, 9.
  • the fluid-conducting connection N is in Figure 3 perpendicular to the plane of the drawing and still bends once perpendicularly at a 90 ° angle and forms the flow path section O, which leads directly into the water outlet 2.
  • Figure 6 again shows a structural unit 1, 20 in the form of a shower element for installation in a wall, which has a first structural section I in the upper section.
  • the mixing and control device MC is arranged there at the level of the water outlet 2.
  • the height of the housing 3 extends over a much larger area.
  • a second construction section II with an operating device 22 is provided in the lower section.
  • the first construction phase I and the second construction phase II are only housed in the same housing 3 (with the exception of the water outlet 2 or the control button of the operating device 22), while the two construction phases I, II do not overlap.
  • the two construction sections I and II are otherwise separated from one another or only electrically connected to one another via lines. There is no mechanical coupling of the operating device 22 to the actuators 16, 17.
  • the present shower element 20 can be completely embedded in a wall. Like it in Figure 6 As can be seen, the shower element 20 is advantageously characterized in that it is very narrow and also not deep. Furthermore it has the advantage that the water outlet is blocked in the first construction phase I. Basically only electrical lines are located along the entire route between the operating device 22 and the water outlet 2, so that no water remains in these areas in the line pipes and the risk of contamination is reduced.
  • connections for hot and cold water A, C are advantageously even at the top, directly attached to the first construction section I, i.e. short waterways are planned.
  • the operating device 22 can be designed in various ways. One possibility is to provide this as a rotary knob. Another possibility is to design the operating device as a button which, if necessary, also enables further functions such as switching on a light. In any case, both the volume flow and the water temperature can be set simultaneously with a structural unit according to the invention.
  • a button that does not have a stop that is to say is basically designed to be infinitely rotatable, can also be provided as an advantageous operating device.
  • further optical elements can also be provided in that, for example, the temperature is displayed via an optical display.
  • the color selection can also be adjusted. For example, it is conceivable to have a display for the preselected standard temperature to be provided in a special color, while an increase in temperature or excessively hot temperatures are displayed, for example, in red. Accordingly, cold temperatures can be symbolically displayed with a blue color.
  • the temperature sensor 7 can in turn ensure that inadvertent selection of a water temperature that is too high is prevented, so that scalding protection is provided.
  • the temperature sensor can interact directly with the actuators 16, 17 or associated control or monitoring units and, if necessary, reduce or even prevent the flow of hot water.
  • structural unit such as structural unit 20 is placed on the wall. Thanks to its narrow design, this is also made possible without taking up a lot of installation space in the shower.
  • the corresponding operating device 22 can also be controlled in a particularly advantageous manner via a computer, a tablet PC, a smartphone or the like via an app.
  • An implementation in or coupling with a facility management system is also conceivable.
  • Standard temperature selections ie presets of a preferred temperature, can be set in this way.
  • the mixing and control device and / or the operating device also has a memory so that such a selection can be set wirelessly with an app or a facility management system.
  • the mixing and control device and the water outlet are fully integrated in a first construction section, the water outlet being arranged on the first construction section and the mixing and control device further comprising two valve devices for hot and cold water so that the volume flow as a whole, but also the temperature, can be set via both valves, specifically during operation by the user himself.
  • the electronics or a control unit can optionally also be arranged in the operating device.
