Definitions
- the present invention relates to a method for introducing foam into a shower cubicle, a steam bath or another sanitary facility suitable for this purpose.
- the invention relates in particular to a method according to the preamble of claim 1.
- Other sanitary facilities suitable for this purpose are characterized in that the introduction of foam is permitted due to the materials used. For example, wash basins, basins for foot baths and plunge pools are such suitable sanitary facilities.
- the object of the present invention is to provide such a method.
- the object is achieved according to the invention if the foam is introduced from a foam generator into the shower cubicle, steam bath or other suitable sanitary facility at a temperature of -15°C to 20°C.
- the temperature of the foam is preferably between 0°C and 18°C.
- the temperature is particularly preferably between 5°C and 15°C.
- the foam preferably has the temperature at an outlet of the foam generator.
- the cold foam offers a special experience on the skin of the user of the shower cubicle, steam bath or other suitable sanitary facility. It also enables a particularly pleasant way of cooling down, as the cold foam has a very refreshing effect without cooling the skin too quickly or painfully.
- the inventive method therefore offers, among other things, a special way of cooling down after wellness treatments at elevated temperatures.
- the use of foam also makes the method resource-saving in terms of water usage.
- the foam is introduced into the shower cubicle or steam bath. This allows the foam to be applied to the entire body, which further improves the wellness experience.
- the foam is produced in the foam generator by blowing air into a mixture of liquid water with a temperature of -18°C to 18°C and soap and the foam produced thereby exiting the foam generator through the outlet, whereby the freezing point of the liquid water, if the temperature of the water is to be below 0°C, is reduced accordingly by adding a component that lowers the freezing point.
- Foam production on the basis of cold water has the advantage that the foam temperature is directly in the desired range and no subsequent cooling of the foam has to be carried out before it is introduced into the respective sanitary facility. This makes the method more energy efficient and process steps can be saved. Likewise, cooling of the air is preferably not required.
- the air exits from a bubble plate at the bottom of the foam generator.
- a bubble plate By using a bubble plate, air can be blown into the foam generator in a cost-effective and efficient manner.
- the bubble size and general consistency of the foam can be influenced.
- the air supply takes place via a fan.
- the fan sucks in air from outside the shower cubicle, steam bath or other suitable sanitary facility. This prevents the fan from sucking in moist air, which could possibly damage the fan.
- the liquid water is supplied to the foam generator via an inlet, with the soap either being supplied via an additional soap inlet or being mixed with the liquid water before it enters the foam generator.
- an inlet simplifies the supply of liquid water to the foam generator.
- the inlet is equipped with a control valve so that the supply and the amount supplied can be regulated.
- the supply of liquid water to the foam generator is fed from a cold water reservoir, wherein the cold water reservoir has a
- Cooling that sets the water temperature By using a cold water reservoir, a sufficient amount of liquid water can be kept at the desired temperature.
- the cold water reservoir is designed in such a way that the one-time volume of the cold water reservoir has enough water for enough foam for one application of the process. In this way, foam can be produced at the set temperature without delay.
- the cooling can also be made particularly efficient.
- the cold water reservoir is preferably connected to a cold water connection. In this way, the cold water reservoir can be refilled.
- a surface level of the mixture of liquid water and soap is controlled by a regulated supply of liquid water and soap. This ensures that there is always sufficient liquid water or a mixture of liquid water and soap in the foam generator and that foam can be generated continuously and under suitable conditions.
- control of the surface level can be based on different measuring devices.
- the supply can preferably be controlled via the position of a float.
- Sensors can also be used to determine the surface level. Such sensors can be based on light signals or electrical conductivity changes, among other things.
- the liquid water is supplied to the foam generator from a flow cooler that is connected to a cold water connection. No reservoir is required here, which saves space, among other things.
- the foam generator has a temperature sensor which is arranged in such a way that the temperature sensor is located in the mixture of water and soap. This allows the cooling in the cold water reservoir to be adjusted in order to achieve the desired water temperature in the foam generator as well.
- the freezing point lowering component is advantageously added to the liquid water in front of or in the cold water reservoir if the water temperature in the cold water reservoir is set to below 0°C. The water temperature in front of the cold water reservoir can therefore be above 0°C.
- the freezing point lowering component In order to prevent changes in the state of aggregation of the water in the cold water reservoir, the freezing point lowering component must be present in the cold water reservoir, since the water temperature there is set to below 0°C.
- a disinfectant preferably hydrogen peroxide, and/or a fragrance is added to the water before the foam generator.
- a disinfectant preferably hydrogen peroxide, and/or a fragrance is added to the water before the foam generator.
- hygiene standards can be maintained.
- fragrances By adding fragrances, the wellness experience can be further improved.
- the process can also be personalized by adding different fragrances.
- the disinfectant and/or fragrance is added after the cold water reservoir. This prevents the disinfectant and/or fragrance from settling in the cold water reservoir, which would result in an increased cleaning frequency of the cold water reservoir.
- the present invention also provides a device for introducing foam into a shower cubicle, a steam bath or another sanitary facility suitable for carrying out the inventive method according to claim 4.
- the invention provides a shower cubicle with a device according to the invention. Furthermore, the invention provides a steam bath cubicle with a device according to the invention.
- the device for generating foam preferably for introducing foam into a shower cubicle, a steam bath or another sanitary facility suitable for this purpose, in particular for carrying out the method according to the invention, in particular in one of the previously described embodiments, relates to a foam generator for supplying air into a mixture of water and soap, the device having a cold water supply for providing water at a temperature between -18°C and 20°C and a hot water supply for providing water at a temperature between 30° and 60°C, a control valve which regulates the temperature in the manner of a conventional mixer tap coupling the cold water supply and hot water supply in front of the foam generator.
- the user of the shower cubicle, steam bath or other sanitary facility suitable for this purpose can adjust the foam temperature according to his needs.
- control valve can also regulate the temperature of the mixture of water and soap in the foam generator in such a way that only water from either the cold water reservoir or the hot water reservoir is added and the temperature is adjusted by the mixture in the foam generator.
- the foam generator has a temperature sensor which is arranged such that the temperature sensor is located within the mixture of water and soap.
- the temperature sensor can be used to adjust the control valve in order to achieve the desired exact temperature of the water in the foam generator.
- the foam generator also preferably has a surface level measuring device for the mixture of water and soap in the foam generator. Using this measuring device, the surface level of the mixture can be adjusted via the control valve.
- a control of the control valve is set such that measurement data from the temperature sensor and the surface level measuring device are used to adjust the temperature of the mixture in the foam generator.
- control valve has, in addition to the connection for the cold water supply and hot water supply, a connection for adding soap.
- the addition to the control valve ensures that there is no soap in the cold water supply or hot water supply that could settle there when this water supply is not being used.
- the foam generator has a drain with a control that allows the foam generator to be quickly emptied and then filled with a mixture of water and soap at a different temperature.
- the desired foam temperature of the user of the device can thus be reached more quickly.
- the drain is connected to a mixed water reservoir, wherein the mixed water reservoir is connected to the control valve in such a way that the mixture of water and soap from the mixed water reservoir can be fed back to the foam generator.
- the mixed water reservoir also has a temperature sensor and a surface level measuring device. The control of the control valve can thus feed the mixture in the mixed water reservoir to the foam generator in order to adjust the temperature of the mixture in the foam generator.
- the mixed water reservoir can have a heater and/or a cooler for adjusting the temperature of the mixture in the mixed water reservoir.
- the device has a second cold water reservoir with a second cooling system.
- the second cold water reservoir and its cooling system are set in such a way that water is kept at a temperature above 0°C, whereby the cold water reservoir then keeps water at a temperature below 0°C.
- the device becomes more energy efficient because only a smaller proportion of the water needs to be kept for special applications with a temperature range below 0°C.
- Figure 1 shows a schematic representation of a first embodiment of a device according to the invention for carrying out the method according to the invention with a cold water connection 2.
- Figure 1 shows a foam generator 3 in which foam 1 is produced for introduction into a shower cubicle, a steam bath or another suitable sanitary facility.
- the foam 1 in the foam generator 3 is produced by blowing air from a bubble plate 4 into a mixture 5 of water and soap.
- the foam 1 produced in this way exits the foam generator 3 through an outlet 6 into the shower cubicle, the steam bath or the other suitable sanitary facility.
- the air supply to the bubble plate 4 is via a fan 7.
- the air supply to the fan 7 is outside the shower cubicle, the steam bath or the other suitable sanitary facility. This means that no moist air gets into the fan 7, which could potentially damage it.
- the foam 1 which is introduced into the shower cubicle, the steam bath or the other sanitary facility suitable for this purpose has a temperature of -5 °C to 20 °C.
- the mixture 5 of water and soap must be in the same temperature range or, if necessary, slightly below this temperature range.
- the foam generator 3 In order to supply the foam generator 3 with the mixture 5, the foam generator 3 has an inlet 8.
- the inlet 8 is connected to a cold water reservoir 9 which is fed from a cold water connection 2.
- the cold water reservoir 9 has a cooling system which brings the water from the cold water connection 2 to the desired or required temperature.
- a freezing point lowering component 10 can be added to the water from the cold water connection 2 before the cold water reservoir 9. If foam temperatures below 0 °C are not to be achieved, there is no need to add a freezing point lowering component 10.
- soap 11 is mixed into the cooled water to produce the mixture 5 for foam generation in the foam generator 3. This requires precise dosing, since the foam properties depend on the ratio between cooled water and soap 11.
- Disinfectant 12 and/or fragrance 13 can also be added between the cold water reservoir 9 and the inlet 8 to the foam generator 3.
- additives other than the freezing point lowering component 10
- the surface level 14 of the mixture 5 of water and soap is measured by means of a measuring device 15 in order to regulate the surface level 14 via this measurement by controlling the inflow of the mixture 5 of water and soap via the inlet 8.
- the foam generator 3 also has a temperature sensor 17, which is located in the mixture 5 of water and soap.
- the temperature sensor 17 can be used to measure the temperature of the mixture 5 in the foam generator 3. This measurement is used to adjust the cooling of the cold water reservoir 9 in order to be able to set the desired foam temperature even more precisely.
- the foam generator 3 also has an outlet 16 with which the foam generator 3 can be emptied. This can be done to clean the foam generator 3 or when the user stops using the device of the first embodiment.
- Figure 2 shows a schematic representation of a device according to a second embodiment for carrying out the method according to the invention with a cold water connection 2 and a hot water connection 18.
- the device shown can introduce foam 1 into a shower cubicle, a steam bath or another suitable sanitary facility in a significantly larger temperature range.
- the device is nevertheless able to carry out the method according to the invention for introducing foam 1 between -15 °C and 20 °C.
- the device of the second embodiment has, as in Figure 1
- the device of the first embodiment shown has a foam generator 3 in which air can be blown into a mixture 5 of water and soap via a bubble plate 4 in order to generate foam 1 which is introduced into the shower cubicle, steam bath or other suitable sanitary facility via an outlet 6 from the foam generator 3. So that the foam temperature can lie within a larger temperature range, the device of the second embodiment has, in addition to the cold water reservoir 9 with the associated cold water connection 2 and the options for adding a freezing point lowering component 10, disinfectant 12 and/or fragrance 13, a hot water reservoir 19 which is fed from a hot water connection 18.
- the water from the cold water reservoir 9 and the hot water reservoir 19 can be mixed with a control valve 20 in front of the inlet 8 in the foam generator 3 so that the water temperature in the foam generator 3 can lie within a larger temperature range.
- the hot water reservoir 19 can have a heater to adjust the temperature in the hot water reservoir.
- the soap 11 is added directly to the control valve 20. This means that soap only needs to be added at one point, even if only water from the cold water reservoir 9 or the hot water reservoir 19 is used.
- a disinfectant 12 and/or a fragrance 13 can also be added to the water from the hot water reservoir 19 between the hot water reservoir and the control valve 20.
- the soap 11, the disinfectant 12 and the fragrance can also be added after the mixer tap 20 and before the inlet 8 in embodiments not shown.
- the foam generator 3 of the device has the same control of the surface level 14 of the mixture 5 as in Figure 1 shown device.
- the foam generator 3 of the device according to the second embodiment has a temperature sensor 17 which is located in the mixture 5.
- the control valve 20 is adjusted via the temperature sensor 17 in order to be able to adjust the foam temperature better.
- the cooling in the cold water reservoir 9 or the heating in the hot water reservoir 19 can also be adjusted via the temperature sensor 17.
- the control valve 20 can also have a control that combines measurements of the surface level and the temperature in the foam generator 3. In this way, when the foam temperature changes, the current temperature and the current volume in the foam generator 3 can be determined in order to introduce the appropriate amount of the mixture of water and soap at the required temperature in order to obtain the desired temperature at the preferred surface level.
- the device of the second embodiment also has an outlet 16, which in this embodiment is also used to discharge the mixture 5 of water and soap from the soap generator 3 when foam 1 is to be produced at a significantly different temperature. This allows the switching speed between introducing foam 1 at the upper end of the temperature range to introducing foam 1 at the lower end of the temperature range and vice versa to be implemented quickly and without long waiting times.
- the control of the outlet 16 is also linked to the control of the control valve 20.
- Figure 3 shows a schematic representation of a device according to a third embodiment for carrying out the method according to the invention with a cold water connection 2 and a hot water connection 18 and a mixed water reservoir 21.
- the device shown can introduce foam 1 in a temperature range corresponding to the temperature range of the second embodiment into a shower cubicle, a steam bath or another sanitary facility suitable for this purpose.
- the device is also able to carry out the method according to the invention for introducing foam 1 between -15 °C and 20 °C.
- the device shown has the same components as the second embodiment, wherein the device additionally has a mixed water reservoir 21 which is connected via a Outlet valve 22 is connected to the outlet 16 of the foam generator 3.
- the mixed water reservoir 21 is also connected to the control valve 20.
- the mixture 5 can be fed in whole or in part via the outlet 16 and the outlet valve 22 into the mixed water reservoir 21 and from there again via the control valve 20 into the foam generator 3. This allows the mixture 5 to be reused in the foam generator 3 and the process becomes more resource-efficient. If, for example, the user of the device wants foam at a different temperature, the mixture 5 can be fed in whole or in part into the mixed water reservoir 21 at the previous temperature and the control valve 20 supplies water from the corresponding cold water reservoir 9, hot water reservoir 19 and mixed water reservoir 21 in such a way that the desired foam temperature is set.
- the mixed water reservoir 21 also has a temperature sensor and a surface level measuring unit so that the control of the control valve 20 in interaction with the drain valve 22 reaches the desired foam temperature as quickly as possible by changing the temperature of the mixture 5 in the foam generator 3.

Das erfinderische Verfahren bietet damit unteranderem eine besondere Möglichkeit der Abkühlung nach Wellnessanwendungen mit erhöhter Temperatur. Durch die Verwendung von Schaum ist das Verfahren außerdem in Bezug auf die Wasserverwendung ressourcenschonend.The cold foam offers a special experience on the skin of the user of the shower cubicle, steam bath or other suitable sanitary facility. It also enables a particularly pleasant way of cooling down, as the cold foam has a very refreshing effect without cooling the skin too quickly or painfully. The inventive method therefore offers, among other things, a special way of cooling down after wellness treatments at elevated temperatures. The use of foam also makes the method resource-saving in terms of water usage.
Vorzugsweise wird der Schaum in die Duschkabine oder das Dampfbad eingeleitet. Dies ermöglicht eine Applikation des Schaums auf dem ganzen Körper, was das Wellnesserlebnis zusätzlich verbessert.Preferably, the foam is introduced into the shower cubicle or steam bath. This allows the foam to be applied to the entire body, which further improves the wellness experience.
Gemäß dem erfindungsgemäßen Verfahren wird der Schaum in dem Schaumgenerator hergestellt, indem Luft in ein Gemisch aus flüssigem Wasser mit einer Temperatur von -18°C bis 18°C und Seife eingeblasen wird und der dadurch erzeugte Schaum durch den Austritt aus dem Schaumgenerator austritt, wobei der Gefrierpunkt des flüssigen Wassers, wenn die Temperatur des Wassers unter 0°C liegen soll, durch Beimischen einer gefrierpunktsenkenden Komponente entsprechend gesenkt wird. Die Schaumerzeugung auf der Basis von kaltem Wasser hat den Vorteil, dass die Schaumtemperatur direkt im gewünschten Bereich liegt und keine nachträgliche Kühlung des Schaums vor der Einleitung in die jeweilige Sanitäreinrichtung vorgenommen werden muss. Das Verfahren wird dadurch energieeffizienter und Verfahrensschritte können dadurch eingespart werden. Ebenfalls bedarf es vorzugsweise keiner Kühlung der Luft. So ergibt sich meistens eine Differenz der Schaumtemperatur am Austritt des Schaumgenerators zu der Wassertemperatur im Schaumgenerator von 1°C bis 5°C. Vorzugsweise wird keine gefrierpunktsenkende Komponente beigemischt, wenn ausschließlich Schaum bei Schaumtemperaturen über 0°C eingeleitet wird.According to the method according to the invention, the foam is produced in the foam generator by blowing air into a mixture of liquid water with a temperature of -18°C to 18°C and soap and the foam produced thereby exiting the foam generator through the outlet, whereby the freezing point of the liquid water, if the temperature of the water is to be below 0°C, is reduced accordingly by adding a component that lowers the freezing point. Foam production on the basis of cold water has the advantage that the foam temperature is directly in the desired range and no subsequent cooling of the foam has to be carried out before it is introduced into the respective sanitary facility. This makes the method more energy efficient and process steps can be saved. Likewise, cooling of the air is preferably not required. This usually results in a difference of 1°C to 5°C between the foam temperature at the outlet of the foam generator and the water temperature in the foam generator. Preferably, no component that lowers the freezing point is added if only foam is introduced at foam temperatures above 0°C.
Gemäß dem erfindungsgemäßen Verfahren tritt die Luft aus einer Sprudelplatte am Boden des Schaumgenerators aus. Durch die Verwendung einer Sprudelplatte kann auf kostengünstige und effiziente Weise Luft in den Schaumgenerator eingeblasen werden. Durch eine geeignete Auswahl bezüglich der Lochgröße, Lochgeometrie und Anordnung der Löcher kann die Blasengröße und generelle Konsistenz des Schaums beeinflusst werden. Vorzugsweise erfolgt die Luftzufuhr über einen Ventilator. Weiter vorzugsweise saugt der Ventilator Luft von außerhalb der Duschkabine, des Dampfbads oder der anderen hierzu geeigneten Sanitäreinrichtung an. Damit wir verhindert, dass der Ventilator feuchte Luft ansaugt, was den Ventilator gegebenenfalls beschädigen könnte. Gemäß dem erfindungsgemäßen Verfahren wird dem Schaumgenerator das flüssige Wasser über einen Einlass zugeführt, wobei die Seife entweder über einen zusätzlichen Seifeneinlass zugeführt wird oder dem flüssigen Wasser vor dem Eintritt in den Schaumgenerator beigemischt wird. Ein solcher Einlass vereinfacht die Versorgung des Schaumgenerators mit flüssigem Wasser. Vorzugsweise ist der Einlass mit einem Regelventil bestückt, sodass die Zufuhr und die zugeführte Menge geregelt werden können.According to the method according to the invention, the air exits from a bubble plate at the bottom of the foam generator. By using a bubble plate, air can be blown into the foam generator in a cost-effective and efficient manner. By making a suitable selection regarding the hole size, hole geometry and arrangement of the holes, the bubble size and general consistency of the foam can be influenced. Preferably, the air supply takes place via a fan. Furthermore, preferably, the fan sucks in air from outside the shower cubicle, steam bath or other suitable sanitary facility. This prevents the fan from sucking in moist air, which could possibly damage the fan. According to the method according to the invention, the liquid water is supplied to the foam generator via an inlet, with the soap either being supplied via an additional soap inlet or being mixed with the liquid water before it enters the foam generator. Such an inlet simplifies the supply of liquid water to the foam generator. Preferably, the inlet is equipped with a control valve so that the supply and the amount supplied can be regulated.
Gemäß dem erfindungsgemäßen Verfahren wird die Zufuhr des flüssigen Wassers in den Schaumgenerator aus einem Kaltwasserreservoir gespeist, wobei das Kaltwasserreservoir eineAccording to the method according to the invention, the supply of liquid water to the foam generator is fed from a cold water reservoir, wherein the cold water reservoir has a
Kühlung aufweist, die die Wassertemperatur einstellt. Durch die Verwendung eines Kaltwasserreservoirs kann eine ausreichende Menge flüssigen Wassers bei der gewünschten Temperatur vorgehalten werden. Vorzugsweise ist das Kaltwasserwasserreservoir derart ausgelegt, dass das einmalige Volumen des Kaltwasserreservoirs Wasser für ausreichend Schaum für eine Anwendung des Verfahrens aufweist. So kann ohne Verzögerung Schaum bei der eingestellten Temperatur erzeugt werden. Durch eine geeignete Dimensionierung des Kaltwasserreservoirs kann außerdem die Kühlung besonders effizient gestaltet werden. Weiter vorzugsweise ist das Kaltwasserreservoir an einen Kaltwasseranschluss angeschlossen. So kann das Kaltwasserreservoir nachgefüllt werden.Cooling that sets the water temperature. By using a cold water reservoir, a sufficient amount of liquid water can be kept at the desired temperature. Preferably, the cold water reservoir is designed in such a way that the one-time volume of the cold water reservoir has enough water for enough foam for one application of the process. In this way, foam can be produced at the set temperature without delay. By appropriately dimensioning the cold water reservoir, the cooling can also be made particularly efficient. Furthermore, the cold water reservoir is preferably connected to a cold water connection. In this way, the cold water reservoir can be refilled.
Vorteilhafte Ausführungsformen der vorliegenden Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the present invention are the subject of the subclaims.
In einem besonders bevorzugten Verfahren wird ein Oberflächenlevel des Gemischs aus flüssigem Wasser und Seife durch eine geregelte Zufuhr von flüssigem Wasser und Seife kontrolliert. Hiermit kann sichergestellt werden, dass stets ausreichend flüssiges Wasser bzw. Gemisch aus flüssigen Wasser und Seife im Schaumgenerator vorhanden ist und so die Schaumerzeugung stetig und bei geeigneten Bedingungen erfolgen kann. Eine solche Regelung des Oberflächenlevels kann auf unterschiedlichen Messvorrichtungen basieren. Vorzugsweise kann die Zufuhr über die Position eines Schwimmers geregelt werden. Ebenfalls können Sensoren zur Bestimmung des Oberflächenlevels genutzt werden. Derartige Sensoren können unter anderem auf Lichtsignalen oder elektrischen Leitfähigkeitsänderungen basieren.In a particularly preferred method, a surface level of the mixture of liquid water and soap is controlled by a regulated supply of liquid water and soap. This ensures that there is always sufficient liquid water or a mixture of liquid water and soap in the foam generator and that foam can be generated continuously and under suitable conditions. Such control of the surface level can be based on different measuring devices. The supply can preferably be controlled via the position of a float. Sensors can also be used to determine the surface level. Such sensors can be based on light signals or electrical conductivity changes, among other things.
In einer anderen bevorzugten Ausführungsform wird die Zufuhr des flüssigen Wassers in den Schaumgenerator aus einem Durchlaufkühler gespeist, der an einen Kaltwasseranschluss angeschlossen ist. Hierbei wird kein Reservoir benötigt, was unteranderem platzsparend ist.In another preferred embodiment, the liquid water is supplied to the foam generator from a flow cooler that is connected to a cold water connection. No reservoir is required here, which saves space, among other things.
In einer bevorzugten Ausführungsform des Verfahrens weist der Schaumgenerator einen Temperatursensor auf, der derart angeordnet ist, dass der Temperatursensor in dem Gemisch aus Wasser und Seife sitzt. Dadurch kann die Kühlung im Kaltwasserreservoir angepasst werden, um die gewünschte Temperatur des Wassers auch im Schaumgenerator zu erreichen. Vorteilhafter Weise wird dem flüssigen Wasser vor oder im Kaltwasserreservoir die gefrierpunktsenkende Komponente beigemischt, wenn die Wassertemperatur im Kaltwasserreservoir auf unter 0°C eingestellt wird. Die Wassertemperatur vor dem Kaltwasserreservoir kann dementsprechend über 0° C liegen. Um Änderungen des Aggregatzustands des Wassers im Kaltwasserreservoirs zu verhindern, muss die gefrierpunktsenkende Komponente aber im Kaltwasserreservoir vorhanden sein, da dort die Temperatur des Wassers auf unter 0 °C eingestellt wird.In a preferred embodiment of the method, the foam generator has a temperature sensor which is arranged in such a way that the temperature sensor is located in the mixture of water and soap. This allows the cooling in the cold water reservoir to be adjusted in order to achieve the desired water temperature in the foam generator as well. The freezing point lowering component is advantageously added to the liquid water in front of or in the cold water reservoir if the water temperature in the cold water reservoir is set to below 0°C. The water temperature in front of the cold water reservoir can therefore be above 0°C. In order to prevent changes in the state of aggregation of the water in the cold water reservoir, the freezing point lowering component must be present in the cold water reservoir, since the water temperature there is set to below 0°C.
In einer besonders vorteilhaften Ausführungsform des Verfahrens wird dem Wasser vor dem Schaumgenerator ein Desinfektionsmittel, vorzugsweise Wasserstoffperoxid, und/oder ein Duftmittel zugesetzt. Durch die Zugabe eines Desinfektionsmittels können Hygienestandards eingehalten werden. Durch die Zugabe von Duftmitteln kann das Wellnesserlebnis weiter verbessert werden. Indem verschiedene Duftmittel zugesetzt werden können, lässt sich das Verfahren außerdem personalisieren.In a particularly advantageous embodiment of the method, a disinfectant, preferably hydrogen peroxide, and/or a fragrance is added to the water before the foam generator. By adding a disinfectant, hygiene standards can be maintained. By adding fragrances, the wellness experience can be further improved. The process can also be personalized by adding different fragrances.
Vorzugsweise wird das Desinfektionsmittel und/ oder das Duftmittel nach dem Kaltwasserreservoir zugesetzt. Somit kann sich das Desinfektionsmittel und/ oder das Duftmittel nicht im Kaltwasserreservoir absetzen, was eine erhöhte Reinigungsfrequenz des Kaltwasserreservoirs zur Folge hätte.Preferably, the disinfectant and/or fragrance is added after the cold water reservoir. This prevents the disinfectant and/or fragrance from settling in the cold water reservoir, which would result in an increased cleaning frequency of the cold water reservoir.
Die vorliegende Erfindung stellt auch eine Vorrichtung zur Einleitung von Schaum in eine Duschkabine, ein Dampfbad oder eine andere hierzu geeignete Sanitäreinrichtung zur Durchführung des erfindungsgemäßen Verfahrens gemäss Anspruch 4.The present invention also provides a device for introducing foam into a shower cubicle, a steam bath or another sanitary facility suitable for carrying out the inventive method according to claim 4.
Daneben stellt die Erfindung eine Duschkabine mit einer erfindungsgemäßen Vorrichtung. Außerdem stellt die Erfindung eine Dampfbadkabine mit einer erfindungsgemäßen Vorrichtung.In addition, the invention provides a shower cubicle with a device according to the invention. Furthermore, the invention provides a steam bath cubicle with a device according to the invention.
Die Vorrichtung zur Erzeugung von Schaum, vorzugsweise zur Einleitung von Schaum in eine Duschkabine, ein Dampfbad oder eine andere hierzu geeignete Sanitäreinrichtung, insbesondere zur Durchführung des erfindungsgemäßen Verfahrens, insbesondere in einer der zuvor beschriebenen Ausführungsformen, betrifft einen Schaumgenerator zur Luftzufuhr in ein Gemisch aus Wasser und Seife, wobei die Vorrichtung eine Kaltwasserzufuhr zur Bereitstellung von Wasser mit einer Temperatur zwischen -18°C und 20°C und eine Warmwasserzufuhr zur Bereitstellung von Wasser mit einer Temperatur zwischen 30° und 60°C aufweist, wobei ein Regelventil, das nach Art einer herkömmlichen Mischbatterie die Temperatur regelt, die Kaltwasserzufuhr und Warmwasserzufuhr vor dem Schaumgenerator koppelt. Mit einer solchen Vorrichtung kann der Nutzers der Duschkabine, des Dampfbads oder der anderen hierzu geeigneten Sanitäreinrichtung die Schaumtemperatur nach seinen Bedürfnissen anpassen. So ist es möglich kalten Schaum, lauwarm Schaum als auch heißen Schaum zuzuführen. Vorzugsweise kann das Regelventil die Temperatur des Gemischs aus Wasser und Seife im Schaumgenerator auch derart regeln, dass jeweils nur Wasser aus entweder dem Kaltwasserreservoir oder dem Warmwasserreservoir zugefügt wird und die Temperatur durch die Mischung im Schaumgenerator eingestellt wird.The device for generating foam, preferably for introducing foam into a shower cubicle, a steam bath or another sanitary facility suitable for this purpose, in particular for carrying out the method according to the invention, in particular in one of the previously described embodiments, relates to a foam generator for supplying air into a mixture of water and soap, the device having a cold water supply for providing water at a temperature between -18°C and 20°C and a hot water supply for providing water at a temperature between 30° and 60°C, a control valve which regulates the temperature in the manner of a conventional mixer tap coupling the cold water supply and hot water supply in front of the foam generator. With such a device, the user of the shower cubicle, steam bath or other sanitary facility suitable for this purpose can adjust the foam temperature according to his needs. It is thus possible to supply cold foam, lukewarm foam and hot foam. Preferably, the control valve can also regulate the temperature of the mixture of water and soap in the foam generator in such a way that only water from either the cold water reservoir or the hot water reservoir is added and the temperature is adjusted by the mixture in the foam generator.
Vorzugsweise weist der Schaumgenerator einen Temperatursensor auf, der derart angeordnet ist, dass sich der Temperatursensor innerhalb des Gemischs aus Wasser und Seife befindet. Mit dem Temperatursensor kann das Regelventil nachgeregelt werden, um die gewünschte exakte Temperatur des Wassers im Schaumgenerator zu erreichen.Preferably, the foam generator has a temperature sensor which is arranged such that the temperature sensor is located within the mixture of water and soap. The temperature sensor can be used to adjust the control valve in order to achieve the desired exact temperature of the water in the foam generator.
Ebenfalls vorzugsweise weist der Schaumgenerator eine Oberflächenlevel-Messvorrichtung für das Gemisch aus Wasser und Seife im Schaumgenerator auf. Über diese Messvorrichtung kann das Oberflächenlevel des Gemischs über das Regelventil eingestellt werden.The foam generator also preferably has a surface level measuring device for the mixture of water and soap in the foam generator. Using this measuring device, the surface level of the mixture can be adjusted via the control valve.
In einer besonders bevorzugten Ausführungsform der Vorrichtung ist eine Regelung des Regelventils derart eingestellt, dass Messdaten des Temperatursensors und der Oberflächenlevel-Messvorrichtung zur Einstellung der Temperatur des Gemischs im Schaumgenerator verwendet werden.In a particularly preferred embodiment of the device, a control of the control valve is set such that measurement data from the temperature sensor and the surface level measuring device are used to adjust the temperature of the mixture in the foam generator.
In einer besonders bevorzugten Ausführungsform der Vorrichtung weist das Regelventil zusätzlich zu dem Anschluss der Kaltwasserzufuhr und Warmwasserzufuhr einen Anschluss zur Beimischung von Seife auf. Durch die Zugabe am Regelventil wird sichergestellt, dass sich keine Seife in der Kaltwasserzufuhr oder Warmwasserzufuhr befindet und sich dort absetzen könnte, wenn diese Wasserzufuhr gerade nicht verwendet wird.In a particularly preferred embodiment of the device, the control valve has, in addition to the connection for the cold water supply and hot water supply, a connection for adding soap. The addition to the control valve ensures that there is no soap in the cold water supply or hot water supply that could settle there when this water supply is not being used.
In einer weiteren bevorzugten Ausführungsform der Vorrichtung weist der Schaumgenerator einen Abfluss mit einer Steuerung auf, die ein schnelles Entleeren des Schaumgenerators und nachfolgendes Befüllen mit einem Gemisch aus Wasser und Seife bei einer anderen Temperatur ermöglicht. Somit kann die gewünschte Schaumtemperatur des Nutzers der Vorrichtung schneller erreicht werden.In a further preferred embodiment of the device, the foam generator has a drain with a control that allows the foam generator to be quickly emptied and then filled with a mixture of water and soap at a different temperature. The desired foam temperature of the user of the device can thus be reached more quickly.
In einer ebenfalls bevorzugten Ausführungsform der Vorrichtung ist der Abfluss an ein Mischwasserreservoir angeschlossen ist, wobei das Mischwasserreservoir derart an das Regelventil angeschlossen ist, dass das Gemisch aus Wasser und Seife aus dem Mischwasserreservoir dem Schaumgenerator wieder zugeführt werden kann. Dies ermöglicht einen besonders ressourcenschonenden Umgang mit dem Gemisch aus Wasser und Seife, da das Gemisch, welches aufgrund einer gewünschten Temperaturänderung des Schaums aus dem Schaumgenerator abgeführt wird, wiederverwendet werden kann. Vorzugsweise weist das Mischwasserreservoir ebenfalls einen Temperatursensor und eine Oberflächenlevel-Messvorrichtung auf. Damit kann die Regelung des Regelventils das Gemisch im Mischwasserreservoir zur Einstellung der Temperatur des Gemischs im Schaumgenerator dem Schaumgenerator zuführen. Ebenfalls vorzugsweise kann das Mischwasserreservoir eine Heizung und/oder eine Kühlung zur Einstellung der Temperatur des Gemischs im Mischwasserreservoir aufweisen.In a likewise preferred embodiment of the device, the drain is connected to a mixed water reservoir, wherein the mixed water reservoir is connected to the control valve in such a way that the mixture of water and soap from the mixed water reservoir can be fed back to the foam generator. This enables particularly resource-saving handling of the mixture of water and soap, since the mixture which is drained from the foam generator due to a desired temperature change in the foam can be reused. Preferably, the mixed water reservoir also has a temperature sensor and a surface level measuring device. The control of the control valve can thus feed the mixture in the mixed water reservoir to the foam generator in order to adjust the temperature of the mixture in the foam generator. Also preferably, the mixed water reservoir can have a heater and/or a cooler for adjusting the temperature of the mixture in the mixed water reservoir.
In einer weiteren bevorzugten Ausführungsform weist die Vorrichtung ein zweites Kaltwasserreservoir mit einer zweiten Kühlung auf. Vorzugsweise ist das zweite Kaltwasserreservoir und dessen Kühlung derart eingestellt, dass Wasser mit einer Temperatur über 0°C vorgehalten wird, wobei das Kaltwasserreservoir dann Wasser mit einer Temperatur unter 0°C vorhält. Dadurch wird die Vorrichtung energieeffizienter, da nur ein geringerer Anteil des Wassers für spezielle Anwendung mit einem Temperaturbereich unter 0°C vorgehalten werden muss.In a further preferred embodiment, the device has a second cold water reservoir with a second cooling system. Preferably, the second cold water reservoir and its cooling system are set in such a way that water is kept at a temperature above 0°C, whereby the cold water reservoir then keeps water at a temperature below 0°C. As a result, the device becomes more energy efficient because only a smaller proportion of the water needs to be kept for special applications with a temperature range below 0°C.

Für die folgenden Ausführungen gilt, dass gleiche Teile durch gleiche Bezugszeichen bezeichnet werden. Sofern in einer Figur Bezugszeichen enthalten sind, auf die in der zugehörigen Figurenbeschreibung nicht näher eingegangen wird, so wird auf vorangehende oder nachfolgende Figurenbeschreibungen Bezug genommen.In the following explanations, identical parts are designated by identical reference symbols. If a figure contains reference symbols that are not discussed in detail in the associated figure description, reference is made to preceding or subsequent figure descriptions.
Gemäß dem erfindungsgemäßen Verfahren hat der Schaum 1, der in die Duschkabine, das Dampfbad oder die andere hierzu geeignete Sanitäreinrichtung eingeleitet wird eine Temperatur von -5 °C bis 20 °C. Um diese Schaumtemperaturen zu erreichen, muss das Gemisch 5 aus Wasser und Seife im gleichen Temperaturbereich oder gegebenenfalls leicht unterhalb dieses Temperaturbereichs liegen. Um den Schaumgenerator 3 mit dem Gemisch 5 zu versorgen, weißt der Schaumgenerator 3 einen Einlass 8 auf. Der Einlass 8 ist mit einem Kaltwasserreservoir 9 verbunden, das von einem Kaltwasseranschluss 2 gespeist wird. Um die Temperatur des Gemischs 5 einzustellen, verfügt das Kaltwasserreservoir 9 über eine Kühlung, die das Wasser aus dem Kaltwasseranschluss 2 auf die gewünschte bzw. benötigte Temperatur bringt. Da unter anderem Schaum 1 mit negativen Temperaturen hergestellt werden soll, muss das flüssige Wasser auf Temperaturen unter 0 °C im Kaltwasserreservoir 9 gebracht werden können. Hierfür kann eine gefrierpunktsenkende Komponente 10 dem Wasser aus dem Kaltwasseranschluss 2 vor dem Kaltwasserreservoir 9 beigefügt werden. Falls keine Schaumtemperaturen unter 0 °C erreicht werden sollen, bedarf es keiner Zugabe einer gefrierpunktsenkenden Komponente 10. Ein hierfür benötigter Anschluss an die Verbindung zwischen Kaltwasseranschluss 2 und Kaltwasserreservoir 9 wird ebenfalls nicht benötigt.According to the method according to the invention, the
Zwischen dem Kaltwasserreservoir 9 und dem Einlass 8 zum Schaumgenerator 3 wird Seife 11 dem gekühlten Wasser beigemischt, um das Gemisch 5 zur Schaumerzeugung im Schaumgenerator 3 herzustellen. Dabei bedarf es einer genauen Dosierung, da die Schaumeigenschaften von dem Verhältnis zwischen gekühltem Wasser und Seife 11 abhängen.Between the cold water reservoir 9 and the inlet 8 to the
Ebenfalls zwischen dem Kaltwasserreservoir 9 und dem Einlass 8 zum Schaumgenerator 3 kann außerdem Desinfektionsmittel 12 und/oder Duftmittel 13 zugesetzt werden. Generell ist es von Vorteil, wenn Zusätze, außer der gefrierpunktsenkenden Komponente 10, zwischen dem Kaltwasserreservoir 9 und dem Einlass 8 in den Schaumgenerator 3 zugesetzt werden. So können sich keine Ablagerungen der Zusätze im Kaltwasserreservoir 9 & bilden, was zu einer benötigten erhöhten Reinigungsfrequenz des Kaltwasserreservoirs 9 führen würde.
Um die Schaumproduktion im Schaumgenerator 3 möglichst effizient und stetig zu gestalten, wird das Oberflächenlevel 14 des Gemischs 5 aus Wasser und Seife mittels einer Messvorrichtung 15 gemessen, um über diese Messung das Oberflächenlevel 14 zu regeln, in dem der Zufluss des Gemischs 5 aus Wasser und Seife über den Einlass 8 kontrolliert wird.In order to make the foam production in the
Der Schaumgenerator 3 weist außerdem einen Temperatursensor 17 auf, der sich in dem Gemisch 5 aus Wasser und Seife befindet. Über den Temperatursensor 17 kann die Temperatur des Gemischs 5 im Schaumgenerator 3 gemessen werden. Über diese Messung wird die Kühlung des Kaltwasserreservoirs 9 nachgeregelt, um so die gewünschte Schaumtemperatur noch präziser einstellen zu können.The

Dabei wird die Seife 11 direkt bei dem Regelventil 20 zugegeben. So muss nur an einer Stelle Seife zugegeben werden, selbst wenn ausschließlich Wasser aus dem Kaltwasserreservoir 9 oder dem Warmwasserreservoir 19 verwendet wird. Dem Wasser aus dem Warmwasserreservoir 19 kann ebenfalls ein Desinfektionsmittel 12 und/oder ein Duftmittel 13 zwischen dem Warmwasserreservoir und dem Regelventil 20 zugesetzt werden. Die Seife 11, das Desinfektionsmittel 12 und das Duftmittel können in nicht gezeigten Ausführungsbeispielen auch nach der Mischbatterie 20 und vor dem Einlass 8 zugesetzt werden.The

Auch weist die Vorrichtung des zweiten Ausführungsbeispiels ebenfalls einen Auslass 16 auf, wobei dieser in dieser Ausführungsform auch dafür verwendet wird, das Gemisch 5 aus Wasser und Seife aus dem Seifengenerator 3 zu entlassen, wenn Schaum 1 mit einer deutlich anderen Temperatur erzeugt werden soll. Dadurch kann die Umschaltgeschwindigkeit zwischen einer Einleitung von Schaum 1 am oberen Ende des Temperaturbereichs zu einer Einleitung von Schaum 1 am unteren Ende des Temperaturbereichs und andersherum zügig und ohne lange Wartezeiten realisiert werden. Die Regelung des Auslass 16 ist dabei ebenfalls mit der Regelung des Regelventils 20 verbunden.The device of the second embodiment also has an

Mit der Vorrichtung der dritten Ausführungsform kann dementsprechend das Gemisch 5 ganz oder teilweise über den Auslass 16 und das Auslassventil 22 in das Mischwasserreservoir 21 geführt werden und von dort wieder über das Regelventil 20 in den Schaumgenerator 3 geführt werden. Dadurch kann das Gemisch 5 im Schaumgenerator 3 wiederverwendet werden und das Verfahren wird ressourcenschonender. Wenn der Nutzer der Vorrichtung zum Beispiel Schaum bei einer geänderten Temperatur wünscht, kann das Gemisch 5 bei der davor vorliegenden Temperatur ganz oder teilweise in das Mischwasserreservoir 21 geleitet werden und das Regelventil 20 leitet Wasser aus dem entsprechenden Kaltwasserreservoir 9, Warmwasserreservoir 19 und Mischwasserreservoir 21 derart zu, dass die gewünschte Schaumtemperatur eingestellt wird.With the device of the third embodiment, the
Hierfür weist das Mischwasserreservoir 21 ebenfalls einen Temperatursensor und eine Oberflächenlevel-Messeinheit auf, damit die Regelung des Regelventils 20 im Zusammenspiel mit dem Abflussventil 22 möglichst rasch die gewünschte Schaumtemperatur durch Änderung der Temperatur des Gemischs 5 im Schaumgenerator 3 erreicht.For this purpose, the
