Definitions
- the present invention relates to a sanitary fitting, comprising a cold water line, a hot water line, a mixing element, a mixed water line and a display.
- the invention also relates to a method for operating a sanitary fitting.
- sanitary fittings are known in which the temperature of the mixed water in the mixed water line is determined by a temperature sensor and the mixed water temperature is signaled to the consumer by means of a suitable display.
- a temperature sensor determines the temperature of the mixed water in the mixed water line.
- the mixed water temperature is signaled to the consumer by means of a suitable display.
- Such a direct determination of the mixed water temperature for setting the display is associated with the considerable disadvantage that only the current mixed water temperature is displayed, which can be subject to significant fluctuations.
- the water in the hot water pipe cools down when the sanitary fitting is closed, it drops to room temperature, so that when the hot water pipe is opened, a temperature is initially displayed that can suddenly increase, so that there is a risk of a user being scalded.
- DE 10 2012 100 097 B4 propose detecting the angle of rotation of an actuating element of a mixing element and using the angle of rotation to display a temperature that is likely to occur in the mixed water line.
- such an arrangement presupposes that the sensor is calibrated to the actuating element.
- the object of the present invention is therefore to eliminate the disadvantages described with reference to the prior art and in particular to specify a sanitary fitting with which a user can be prevented from being scalded in an alternative and simple, in particular energy-saving manner.
- the sanitary fitting includes a cold water line, which can preferably be connected to a cold water line of a building with a cold water connection.
- the sanitary fitting also includes a hot water line, which preferably has a hot water connection to the hot water house line of a building or, for example, to the hot water outlet of an instantaneous water heater.
- the cold water line and the hot water line lead to a mixing element.
- a mixed water line is connected to the mixing element, which leads in particular to a mixed water outlet of the sanitary fitting.
- the mixing element has in particular an adjusting element that can be adjusted manually or by a controller, with which the cold water volume flow flowing from the cold water line into the mixed water line and the hot water volume flow flowing from the hot water line into the mixed water line can be adjusted. Accordingly, the temperature of the mixed water can be set via the mixing element.
- the mixing element can be designed, for example, as a single-lever mixer or as a classic two-handle fitting.
- the sanitary fitting also preferably comprises a fitting body in which the cold water line, the hot water line, the mixing element and the mixed water line are arranged or at least attached.
- the sanitary fitting also includes a display.
- the display can be a digital display that displays numerical values.
- the display can also have a number of fields, with fewer fields being activated to display a supposedly lower mixed water temperature and more fields being activated to display a supposedly higher mixed water temperature.
- the display is integrated into the body of the fitting, so that the display can be perceived by a user.
- the display can, for example, be on a top side of the sanitary fitting be arranged.
- the display illuminates a surface or an area, so that the display can be perceived over the illuminated area.
- the display has at least one light source for emitting light with different colors, the color of the light being variable.
- the display can have at least one first light source for emitting light with a first emission color and at least one second light source for emitting light with a second emission color, the at least one first light source and the at least one second light source being arranged in relation to one another such that the light emitted by the light sources is mixed in such a way that a user only perceives the mixed light and thus the color of the mixed light produced by the light mixing.
- the light sources are embodied in particular as LEDs which are arranged in the immediate vicinity of one another and the light emitted from them is mixed into light which can be perceived by a user.
- the sanitary fitting has a first sensor for determining a cold water volume flow in the cold water line, which is also referred to as a cold water volume flow sensor.
- the sanitary fitting has a second sensor for determining a hot water volume flow in the hot water line, which is also referred to as a hot water volume flow sensor.
- volume flow rate sensors are designed and arranged in such a way that the volume flow rate in the corresponding water pipe can be inferred from a signal (e.g. a voltage) emitted by the volume flow rate sensor, particularly if parameters (such as diameter) of the water pipe are known.
- the output signal of such volume flow sensors therefore depends on the volume flow flowing through the associated water pipe.
- the volume flow in the water pipe is not only indirectly inferred by other parameters (such as the orientation of an actuating element of a mixing element).
- the display is changed as a function of the cold water volume flow and the hot water volume flow.
- the function can be a quotient between the cold water volume flow and the hot water volume flow or a difference between the cold water volume flow and the hot water volume flow. If the quotient that can be determined by the cold water volume flow sensor and the hot water volume flow sensor or the difference that can be determined changes, the display also changes.
- the display shows a visualization that represents the expected temperature of the mixed water based on the volume flows, and is therefore independent of the current absolute temperature of the mixed water.
- the mixing element of such a sanitary fitting is set in such a way that only hot water flows when the sanitary fitting is opened, a visualization representing a high mixed water temperature is immediately displayed, even if the water exiting the mixed water line initially has a very low temperature (roughly room temperature). having.
- Such a sanitary fitting is particularly useful in heavily frequented sanitary rooms, since users are not familiar with the characteristic temperature curves of such sanitary fittings that are unknown to them.
- one is based on the volume flows of the hot and cold water Display is also particularly useful if the mixing element is not set directly manually by the user (as in the case of a single-lever mixer or a two-handle mixer), but by an electronic control.
- the color of the light emitted by the at least one light source of the display and perceived by the user changes as a function of the cold water volume flow and the hot water volume flow. For example, with a change in the ratio of the volume flows, which corresponds to an assumed increase in temperature, the color of the light can be changed to reddish, while with a change in the ratio of the volume flows, which corresponds to an assumed decrease in temperature, the color of the perceptible light is changed to bluish.
- the cold water volume flow sensor is directly connected to the at least one first light source, for example a blue light-emitting LED, while the hot water volume flow sensor is directly connected to the at least one second light source, for example a red light-emitting LED .
- the volume flow sensors generate a signal that is proportional to the volume flow in the corresponding water pipe.
- the respective volume flow sensor can output a higher voltage as the volume flow increases.
- the at least one first light source and the at least one second light source are preferably designed so that with the Volume flow sensors provided voltages as input voltages, the light intensity emitted by the light sources increases.
- the volume flow sensors can thus be connected directly to the light sources, which keeps the circuitry effort very low.
- the sanitary fitting has a controller and in particular a controller for setting the display, the controller being connected to the cold water volume flow sensor and the hot water volume flow sensor and to the display.
- the controller is connected to the at least one light source of the display.
- Such a controller can also be connected to a drive for an actuating element of the mixing element.
- the cold water volume flow sensor and the hot water volume flow sensor are each arranged as a turbine in the cold water line and the hot water line, for example, so that the voltage generated by the turbine can be applied directly to a light source.
- Such turbines can also serve as a power source for the display and/or a controller, so that no separate power source is required.
- the sanitary fitting shown comprises a cold water line 1 in which a cold water flow rate sensor 6 is arranged, and a hot water line 2 in which a hot water flow rate sensor 7 is arranged.
- the cold water line 1 and the hot water line 2 lead to a mixing element 3 designed, for example, as a single-lever mixing cartridge, to which a mixed water line 4 leading to a mixed water outlet is connected.
- the mixing element 3 With the mixing element 3, the ratio of hot water and cold water in the mixed water line and thus the temperature of the mixed water can be adjusted.
- the sanitary fitting also includes a display 5 with a first light source 5.1 and a second light source 5.2.
- the display 5 is connected to the cold water volume flow sensor 6 and the hot water volume flow sensor 7 .
- the first light source 5.1 is, for example, an LED that emits blue light
- the second light source 5.2 is, for example, an LED that emits red light.
- the display 5 is set up in such a way that the color of the light emitted by the display 5 is changed as a function of the ratio of cold water volume flow and hot water volume flow determined by the volume flow sensors 6 and 7 . For example, if only cold water flows, blue light is emitted. On the other hand, when only hot water flows, light of red color is emitted. In this way, an assumed temperature of the mixed water is displayed, so that the display 5 is not subject to any fluctuations in the temperature of the hot or cold water.

Aufgabe der vorliegenden Erfindung ist es daher, die mit Bezug zum Stand der Technik beschriebenen Nachteile zu beseitigen und insbesondere eine Sanitärarmatur anzugeben, mit der auf alternative und einfache, insbesondere energiesparende Weise verhindert werden kann, dass sich ein Benutzer verbrüht.The object of the present invention is therefore to eliminate the disadvantages described with reference to the prior art and in particular to specify a sanitary fitting with which a user can be prevented from being scalded in an alternative and simple, in particular energy-saving manner.
Eine mögliche Lösung für diese Aufgabe ist jeweils in Anspruch 1 und Anspruch 9 angegeben. Mögliche weitere Lösungen und vorteilhafte Weiterbildungen sind in den abhängigen Ansprüchen und in der Beschreibung angegeben, wobei einzelne Merkmale aus den abhängigen Ansprüchen und der Beschreibung in technisch sinnvoller Weise miteinander kombinierbar sind. Mit Bezug zu der Sanitärarmatur offenbarte Merkmale lassen sich auf das Verfahren übertragen und umgekehrt.A possible solution to this problem is specified in
Die Sanitärarmatur umfasst eine Kaltwasserleitung, die bevorzugt mit einem Kaltwasseranschluss an eine Kaltwasserhausleitung eines Gebäudes anschließbar ist. Die Sanitärarmatur umfasst zudem eine Heißwasserleitung, die bevorzugt mit einem Heißwasseranschluss an die Heißwasserhausleitung eines Gebäudes oder beispielsweise an den Heißwasserausgang eines Durchlauferhitzers anschließbar ist.The sanitary fitting includes a cold water line, which can preferably be connected to a cold water line of a building with a cold water connection. The sanitary fitting also includes a hot water line, which preferably has a hot water connection to the hot water house line of a building or, for example, to the hot water outlet of an instantaneous water heater.
Die Kaltwasserleitung und die Heißwasserleitung führen zu einem Mischorgan.The cold water line and the hot water line lead to a mixing element.
An das Mischorgan ist eine Mischwasserleitung angeschlossen, die insbesondere zu einem Mischwasserauslass der Sanitärarmatur führt.A mixed water line is connected to the mixing element, which leads in particular to a mixed water outlet of the sanitary fitting.
Das Mischorgan weist insbesondere ein manuell oder durch eine Steuerung einstellbares Stellelement auf, mit welchem der von der Kaltwasserleitung in die Mischwasserleitung fließende Kaltwasservolumenstrom und der von der Heißwasserleitung in die Mischwasserleitung fließende Heißwasservolumenstrom eingestellt werden kann. Dementsprechend kann über das Mischorgan die Temperatur des Mischwassers eingestellt werden. Das Mischorgan kann beispielsweise als Einhebelmischer oder auch als klassische Zweigriffarmatur ausgebildet sein.The mixing element has in particular an adjusting element that can be adjusted manually or by a controller, with which the cold water volume flow flowing from the cold water line into the mixed water line and the hot water volume flow flowing from the hot water line into the mixed water line can be adjusted. Accordingly, the temperature of the mixed water can be set via the mixing element. The mixing element can be designed, for example, as a single-lever mixer or as a classic two-handle fitting.
Die Sanitärarmatur umfasst zudem bevorzugt einen Armaturenkörper, in dem die Kaltwasserleitung, die Heißwasserleitung, das Mischorgan und die Mischwasserleitung angeordnet oder zumindest angebracht sind.The sanitary fitting also preferably comprises a fitting body in which the cold water line, the hot water line, the mixing element and the mixed water line are arranged or at least attached.
Die Sanitärarmatur umfasst zudem eine Anzeige. Die Anzeige kann beispielsweise eine digitale Anzeige sein, die Zahlenwerte anzeigt. Alternativ kann die Anzeige auch mehrere Felder aufweisen, wobei zur Anzeige einer vermeintlich niedrigeren Mischwassertemperatur weniger Felder und zur Anzeige einer vermeintlich höheren Mischwassertemperatur mehr Felder aktiviert werden. Die Anzeige ist insbesondere in den Armaturenkörper integriert, sodass die Anzeige von einem Benutzer wahrnehmbar ist. Die Anzeige kann beispielsweise auf einer Oberseite der Sanitärarmatur angeordnet sein. Es kann aber auch vorgesehen sein, dass die Anzeige eine Fläche oder einen Bereich anstrahlt, sodass über den angestrahlten Bereich die Anzeige wahrnehmbar ist.The sanitary fitting also includes a display. For example, the display can be a digital display that displays numerical values. Alternatively, the display can also have a number of fields, with fewer fields being activated to display a supposedly lower mixed water temperature and more fields being activated to display a supposedly higher mixed water temperature. In particular, the display is integrated into the body of the fitting, so that the display can be perceived by a user. The display can, for example, be on a top side of the sanitary fitting be arranged. However, it can also be provided that the display illuminates a surface or an area, so that the display can be perceived over the illuminated area.
Bevorzugt ist aber, dass die Anzeige mindestens eine Lichtquelle zur Emission von Licht mit unterschiedlichen Farben aufweist, wobei die Farbe des Lichts veränderbar ist. So kann die Anzeige beispielsweise mindestens eine erste Lichtquelle zur Emission von Licht mit einer ersten Emissionsfarbe und mindestens eine zweite Lichtquelle zur Emission von Licht mit einer zweiten Emissionsfarbe aufweisen, wobei die mindestens eine erste Lichtquelle und die mindestens eine zweite Lichtquelle so zueinander angeordnet sind, dass das von den Lichtquellen emittierte Licht so gemischt wird, dass ein Benutzer nur das gemischte Licht und somit die durch die Lichtmischung entstehende Farbe des gemischten Lichts wahrnimmt. Die Lichtquellen sind insbesondere als LEDs ausgebildet, die in unmittelbarer Nähe zueinander angeordnet sind und deren jeweils emittiertes Licht zu für einen Benutzer wahrnehmbarem Licht gemischt wird.However, it is preferred that the display has at least one light source for emitting light with different colors, the color of the light being variable. For example, the display can have at least one first light source for emitting light with a first emission color and at least one second light source for emitting light with a second emission color, the at least one first light source and the at least one second light source being arranged in relation to one another such that the light emitted by the light sources is mixed in such a way that a user only perceives the mixed light and thus the color of the mixed light produced by the light mixing. The light sources are embodied in particular as LEDs which are arranged in the immediate vicinity of one another and the light emitted from them is mixed into light which can be perceived by a user.
Es wird nun auch vorgeschlagen, dass die Sanitärarmatur einen ersten Sensor zur Bestimmung eines Kaltwasservolumenstroms in der Kaltwasserleitung aufweist, welcher auch als Kaltwasservolumenstromsensor bezeichnet wird.It is now also proposed that the sanitary fitting has a first sensor for determining a cold water volume flow in the cold water line, which is also referred to as a cold water volume flow sensor.
Zudem wird vorgeschlagen, dass die Sanitärarmatur einen zweiten Sensor zur Bestimmung eines Heißwasservolumenstroms in der Heißwasserleitung aufweist, welcher auch als Heißwasservolumenstromsensor bezeichnet wird.In addition, it is proposed that the sanitary fitting has a second sensor for determining a hot water volume flow in the hot water line, which is also referred to as a hot water volume flow sensor.
Solche Volumenstromsensoren sind so ausgebildet und angeordnet, dass von einem von dem Volumenstromsensor ausgegebenen Signal (beispielsweise eine Spannung) auf den Volumenstrom in der entsprechenden Wasserleitung geschlossen werden kann, insbesondere wenn Parameter (wie Durchmesser) der Wasserleitung bekannt sind. Das Ausgangssignal solcher Volumenstromsensoren hängt also von dem durch die zugehörige Wasserleitung fließenden Volumenstrom ab. Es wird somit nicht durch andere Parameter (wie beispielsweise die Ausrichtung eines Stellelements eines Mischorgans) nur indirekt auf den Volumenstrom in der Wasserleitung geschlossen.Such volume flow rate sensors are designed and arranged in such a way that the volume flow rate in the corresponding water pipe can be inferred from a signal (e.g. a voltage) emitted by the volume flow rate sensor, particularly if parameters (such as diameter) of the water pipe are known. The output signal of such volume flow sensors therefore depends on the volume flow flowing through the associated water pipe. Thus, the volume flow in the water pipe is not only indirectly inferred by other parameters (such as the orientation of an actuating element of a mixing element).
Es wird nun insbesondere weiter vorgeschlagen, dass die Anzeige als eine Funktion des Kaltwasservolumenstroms und des Heißwasservolumenstroms verändert wird. So kann die Funktion ein Quotient zwischen dem Kaltwasservolumenstrom und dem Heißwasservolumenstrom sein oder eine Differenz zwischen dem Kaltwasservolumenstrom und dem Heißwasservolumenstrom. Wenn sich also der durch den Kaltwasservolumenstromsensor und den Heißwasservolumenstromsensor bestimmbare Quotient beziehungsweise die bestimmbare Differenz ändert, so ändert sich auch die Anzeige.In particular, it is now further proposed that the display is changed as a function of the cold water volume flow and the hot water volume flow. The function can be a quotient between the cold water volume flow and the hot water volume flow or a difference between the cold water volume flow and the hot water volume flow. If the quotient that can be determined by the cold water volume flow sensor and the hot water volume flow sensor or the difference that can be determined changes, the display also changes.
Auf diese Weise zeigt die Anzeige eine Visualisierung an, die aufgrund der Volumenströme die erwartbare Temperatur des Mischwassers repräsentiert, und ist somit unabhängig von der jeweils aktuell vorliegenden absoluten Temperatur des Mischwassers. Wird beispielsweise bei einer solchen Sanitärarmatur das Mischorgan so eingestellt, dass beim Öffnen der Sanitärarmatur ausschließlich Heißwasser fließt, so wird unmittelbar eine eine hohe Mischwassertemperatur repräsentierende Visualisierung angezeigt, auch wenn das aus der Mischwasserleitung austretenden Wasser anfangs noch eine sehr niedrige Temperatur (etwa der Raumtemperatur) aufweist. Eine solche Sanitärarmatur ist insbesondere in hoch frequentierten Sanitärräumen nützlich, da Benutzer mit den charakteristischen Temperaturverläufen solcher ihnen nicht bekannter Sanitärarmaturen nicht vertraut sind. Insbesondere ist eine solche auf den Volumenströmen des Heiß- und Kaltwassers basierende Anzeige auch besonders sinnvoll, wenn das Mischorgan nicht unmittelbar manuell durch den Benutzer (wie im Fall eines Einhebelmischers oder einer Zweigriffarmatur) eingestellt wird, sondern durch eine elektronische Steuerung.In this way, the display shows a visualization that represents the expected temperature of the mixed water based on the volume flows, and is therefore independent of the current absolute temperature of the mixed water. If, for example, the mixing element of such a sanitary fitting is set in such a way that only hot water flows when the sanitary fitting is opened, a visualization representing a high mixed water temperature is immediately displayed, even if the water exiting the mixed water line initially has a very low temperature (roughly room temperature). having. Such a sanitary fitting is particularly useful in heavily frequented sanitary rooms, since users are not familiar with the characteristic temperature curves of such sanitary fittings that are unknown to them. In particular, one is based on the volume flows of the hot and cold water Display is also particularly useful if the mixing element is not set directly manually by the user (as in the case of a single-lever mixer or a two-handle mixer), but by an electronic control.
Bevorzugt ist nun, dass sich als Funktion des Kaltwasservolumenstroms und des Heißwasservolumenstroms die Farbe des von der mindestens einen Lichtquelle der Anzeige emittierten und vom Benutzer wahrgenommenen Lichts ändert. Beispielsweise kann bei einer Änderung des Verhältnisses der Volumenströme, die einer vermeintlichen Temperaturerhöhung entspricht, die Farbe des Lichts ins Rötliche geändert werden, während bei einer Änderung des Verhältnisses der Volumenströme, die einer vermeintlichen Temperaturabsenkung entspricht, die Farbe des wahrnehmbaren Lichts ins Bläuliche geändert wird.It is now preferred that the color of the light emitted by the at least one light source of the display and perceived by the user changes as a function of the cold water volume flow and the hot water volume flow. For example, with a change in the ratio of the volume flows, which corresponds to an assumed increase in temperature, the color of the light can be changed to reddish, while with a change in the ratio of the volume flows, which corresponds to an assumed decrease in temperature, the color of the perceptible light is changed to bluish.
In einer Ausführungsform kann hierzu vorgesehen sein, dass der Kaltwasservolumenstromsensor mit der mindestens einen ersten Lichtquelle, beispielsweise einer blaues Licht emittierenden LED, direkt verbunden ist, während der Heißwasservolumenstromsensor direkt mit der mindestens einen zweiten Lichtquelle, beispielsweise einer rotes Licht emittierenden LED, direkt verbunden ist.In one embodiment, it can be provided that the cold water volume flow sensor is directly connected to the at least one first light source, for example a blue light-emitting LED, while the hot water volume flow sensor is directly connected to the at least one second light source, for example a red light-emitting LED .
In diesem Zusammenhang ist insbesondere vorgesehen, dass die Volumenstromsensoren ein zu dem Volumenstrom in der entsprechenden Wasserleitung proportionales Signal erzeugen. So kann beispielsweise der jeweilige Volumenstromsensor mit steigendem Volumenstrom eine höhere Spannung ausgeben.In this context, it is provided in particular that the volume flow sensors generate a signal that is proportional to the volume flow in the corresponding water pipe. For example, the respective volume flow sensor can output a higher voltage as the volume flow increases.
Die mindestens eine erste Lichtquelle und die mindestens eine zweite Lichtquelle sind bevorzugt so ausgebildet, dass mit von den Volumenstromsensoren bereitgestellten Spannungen als Eingangsspannungen die von den Lichtquellen emittierte Lichtintensität steigt. Somit können die Volumenstromsensoren unmittelbar an die Lichtquellen angeschlossen werden, was den schaltungstechnischen Aufwand sehr gering hält.The at least one first light source and the at least one second light source are preferably designed so that with the Volume flow sensors provided voltages as input voltages, the light intensity emitted by the light sources increases. The volume flow sensors can thus be connected directly to the light sources, which keeps the circuitry effort very low.
Es kann aber auch vorgesehen sein, dass die Sanitärarmatur eine Steuerung und insbesondere eine Steuerung zur Einstellung der Anzeige aufweist, wobei die Steuerung mit dem Kaltwasservolumenstromsensor und dem Heißwasservolumenstromsensor sowie mit der Anzeige verbunden ist. Insbesondere ist die Steuerung mit der mindestens einen Lichtquelle der Anzeige verbunden. Eine solche Steuerung kann auch mit einem Antrieb für ein Stellelement des Mischorgans verbunden sein.However, it can also be provided that the sanitary fitting has a controller and in particular a controller for setting the display, the controller being connected to the cold water volume flow sensor and the hot water volume flow sensor and to the display. In particular, the controller is connected to the at least one light source of the display. Such a controller can also be connected to a drive for an actuating element of the mixing element.
Der Kaltwasservolumenstromsensor und der Heißwasservolumenstromsensor sind beispielsweise jeweils als Turbine in der Kaltwasserleitung und der Heißwasserleitung angeordnet, sodass die von der Turbine erzeugte Spannung unmittelbar an einer Lichtquelle angelegt werden kann. Solche Turbinen können auch als Energiequelle der Anzeige und/oder einer Steuerung dienen, so dass keine separate Energiequelle benötigt wird.The cold water volume flow sensor and the hot water volume flow sensor are each arranged as a turbine in the cold water line and the hot water line, for example, so that the voltage generated by the turbine can be applied directly to a light source. Such turbines can also serve as a power source for the display and/or a controller, so that no separate power source is required.
Entsprechend den vorstehenden Ausführungen wird auch ein Verfahren zum Betreiben einer Sanitärarmatur vorgeschlagen, welches zumindest die folgenden Schritte umfasst:

- Bestimmen des Kaltwasservolumenstroms, insbesondere mit dem Kaltwasservolumenstromsensor,

Die Sanitärarmatur umfasst zudem eine Anzeige 5 mit einer ersten Lichtquelle 5.1 und einer zweiten Lichtquelle 5.2. Die Anzeige 5 ist mit dem Kaltwasservolumenstromsensor 6 und dem Heißwasservolumenstromsensor 7 verbunden.The sanitary fitting also includes a
