Description

Die Erfindung betrifft eine Vorrichtung umfassend eine Vorrichtung zur Steuerung mindestens eines Funktionsteils einer Bade- oder Whirlpoolwanne.The invention relates to a device comprising a device for controlling at least one functional part of a bath or spa tub.

Badewannen sind in vielfältigen Ausführungen erhältlich. Herkömmliche Badewannen weisen eine verschließbare Ablauföffnung im Wannenboden und eine Überlauföffnung im oberen Bereich der Wannenwandung auf. Das Befüllen von Badewannen erfolgt üblicherweise mittels einer neben der Badewanne angeordneten Wannenzulaufarmatur, wobei die Zulaufmündung auch in die Wannenwandung integriert, insbesondere an der Überlauföffnung angeordnet sein kann. Die Temperatur des Badewassers wird mittels der Wannenzulaufarmatur eingestellt, wobei der Benutzer üblicherweise eine Hand in das Badewasser hält, um zu fühlen, ob die Wassertemperatur für ihn angenehm ist. Wenn die Badewassertemperatur unangenehm kalt oder unangenehm heiß ist, wird warmes oder kaltes Wasser zugegeben, wobei jedoch häufig mehr Wasser als eigentlich erforderlich verbraucht wird. Mitunter wird sogar ein Teil des frisch eingefüllten Badewassers über den Wannenablauf oder -überlauf abgelassen, um für die Einstellung einer angenehmen Badewassertemperatur warmes oder kaltes Wasser in die Badewanne einfüllen zu können. Eine wassersparende und komfortablere Temperatureinstellung ermöglichen Wannenzulaufarmaturen, die ein Thermostat-Mischventil aufweisen. Jedoch kommt es auch bei der Verwendung von Thermostat-Mischventilen häufig zu einem unerwünschten Wassermehrverbrauch, beispielsweise dann, wenn eine so ausgestattete Badewanne von Personen mit unterschiedlichen Temperaturvorlieben genutzt wird und von einem der Nutzer zu spät erkannt wird, dass das Thermostat-Mischventil auf eine andere als die individuell gewünschte Wassertemperatur eingestellt ist.Bathtubs are available in a variety of designs. Conventional baths have a closable drain opening in the tub bottom and an overflow opening in the upper region of the tub wall. The filling of bathtubs is usually carried out by means of a bath inlet valve arranged next to the bath, wherein the inlet opening can also be integrated into the tub wall, in particular can be arranged at the overflow opening. The temperature of the bath water is adjusted by means of the bath inlet fitting, whereby the user usually holds a hand in the bath water in order to feel whether the water temperature is comfortable for him. If the bathing water temperature is uncomfortably cold or unpleasantly hot, hot or cold water is added, but often more water is consumed than is actually required. Sometimes even a part of the freshly filled bathing water is drained through the tub drain or overflow to be able to fill in the bathtub for setting a pleasant bath water temperature warm or cold water. A water-saving and more comfortable temperature setting allow pan inlet fittings, which have a thermostatic mixing valve. However, it also comes with the use of thermostatic mixing valves often to an undesirable additional water consumption, for example, when a so-equipped bathtub is used by people with different temperature preferences and is recognized by one of the users too late that the thermostatic mixing valve is set to a different than the individually desired water temperature.

Bekannte Whirlpoolwannen (Hydromassagewannen) sind mit einem Bediengerät zur getrennten oder gemeinsamen Ansteuerung mehrerer Hydrodüsen bzw. Pumpen sowie gegebenenfalls zur Einstellung der Wassertemperatur ausgestattet. Werden solche Whirlpoolwannen von Personen mit unterschiedlichen Massage- und/oder Wassertemperaturvorlieben genutzt, kommt es ebenfalls oft zu einem unnötigen Energieverbrauch, wenn von einer der Personen zu spät erkannt wird, dass die zuletzt eingestellte Pumpen- oder Heizleistung nicht der individuell gewünschten Wasserstrahlströmung bzw. Wassertemperatur entspricht.Known whirlpool baths (hydromassage tubs) are equipped with a control unit for the separate or joint control of several hydro nozzles or pumps and optionally for adjusting the water temperature. If such whirlpool baths are used by persons with different massage and / or water temperature preferences, it also often leads to unnecessary energy consumption, if one of the persons realized too late that the last set pump or heating power not individually desired water jet flow or water temperature equivalent.

Darüber hinaus ist aus der US 6, 770, 043 B1 ein hydrotherapeutisches System für eine Badwanne oder Whirlpoolanordnung bekannt, das aus einer Sitzvorrichtung mit einer daran installierten Düsenanordnung besteht, die sich in einem mit Wasser gefüllten Whirlpool befindet. Die Düsenanordnung ist über eine Computersteuerung vom Benutzer regelbar. Die Computersteuerung weist unter anderem einen Speicher auf, in dem Programmabläufe gespeichert und vom Benutzer abgerufen werden können. Die Auswahl des Programms geschieht über ein Eingabegerät, wobei sich der Benutzer zuvor mittels Fingerabdruck oder Stimmerkennung autorisiert. Des Weiteren kann sich der Benutzer während des Programmablaufs von einem Monitorsystem unterhalten lassen oder an einem Personalcomputer arbeiten.In addition, from the US Pat. No. 6,770,043 B1 a hydrotherapeutic system for a bath tub or whirlpool assembly is known, which consists of a seat device with a nozzle assembly installed thereon, which is located in a water-filled hot tub. The nozzle arrangement can be controlled by the user via a computer control. Among other things, the computer control has a memory in which program sequences can be stored and retrieved by the user. The selection of the program is done via an input device, whereby the user previously authorized by means of fingerprint or voice recognition. Furthermore, during program execution, the user may be entertained by a monitor system or work on a personal computer.

In der DE 201 04 810 U1 ist ein Erkennungssystem zur Aktivierung von Geräten und Vorrichtungen in Badezimmern durch biometrische Identifikationsdaten (z. B. Fingerabdrücke) offenbart. Die Nutzung der Steuervorrichtung und damit die Verwendung von Betätigungsprogrammen sind dabei nur dann möglich, wenn das System den autorisierten Benutzer erkannt hat. Nach der erfolgreichen Autorisierung kann der Benutzer über eine Tastatur die gewünschten Programmeinstellungen vornehmen, die ihm dann auf einem Bildschirm angezeigt werden. Dadurch, dass das System auch eine elektronische Datenbank umfasst, können auch automatisch gespeicherte Programmabläufe gestartet werden, die vom Benutzer bevorzugt werden.In the DE 201 04 810 U1 For example, there is disclosed a detection system for activating bathroom appliances and devices through biometric identification data (eg, fingerprints). The use of the control device and thus the use of actuation programs are only possible if the system has recognized the authorized user. After successful authorization, the user can use a keyboard to make the desired program settings, which are then displayed on a screen. Because the system also includes an electronic database, automatically stored program sequences which are preferred by the user can also be started.

In die Ablaufgarnitur 16 ist zwischen dem zur Heizeinrichtung 18 abzweigenden Rohrstutzen 16.3 und der als Geruchverschluss dienenden Umlenkung 16.1 eine Klappe oder Kugel eingesetzt, die Teil eines Zweiwege-Verschlusses ist. Der Zweiwege-Verschluss und das Ablaufventil sind mit einem elektrischen Stellantrieb 17 gekoppelt, der über die Steuereinheit 5 angesteuert wird.In the pop-up 16 is used between the branch pipe 16.3 branching off to the heater 18 and the deflector serving as odor trap 16.1, a flap or ball, which is part of a two-way closure. The two-way closure and the drain valve are coupled to an electric actuator 17, which is controlled via the control unit 5.

Gemäß einer bevorzugten Ausgestaltung der erfindungsgemäßen Vorrichtung steht die elektronische Steuereinheit 5 außerdem mit einer Dosiereinrichtung oder Pumpe (nicht gezeigt) für eine Zugabe von Schaumbadmitteln und/oder Duftstoffen in die Wanne 2 in Wirkverbindung. Die hierzu verwendete Dosiereinrichtung ist gegebenenfalls mit einem elektronischen Absperrventil oder elektronischen Rohrunterbrecher versehen, um eine Rückflusssicherheit zu gewährleisten.According to a preferred embodiment of the device according to the invention, the electronic control unit 5 is also in operative connection with a metering device or pump (not shown) for adding foam bathing agents and / or fragrances into the tub 2. The metering device used for this purpose is optionally with an electronic shut-off valve or electronic pipe breaker provided to ensure a backflow safety.

An der Steuereinheit 5 sind ferner ein Temperatursensor 21 zur Messung der Badewassertemperatur sowie mindestens ein Wasserstandssensor 22 angeschlossen. Der Temperatursensor 21 ist vorzugsweise in der Ablaufgarnitur 16 nahe dem Ablaufventil angeordnet.At the control unit 5, a temperature sensor 21 for measuring the bath water temperature and at least one water level sensor 22 are also connected.

Füllventil 9, Ablaufventil, Stellantrieb 17, Heizeinrichtung 18 und Pumpe 19) der Wanne sowie die Sensoren (Temperatursensor 21, Wasserstandssensor 22) sind über Steuerleitungen bzw. Signalleitungen 6, 23-27 an der Steuereinheit 5 angeschlossen. Alternativ und vorzugsweise können das Eingabegerät 1.1, 1.2, die Funktionsteile 9, 12, 17, 18, 19 und die Sensoren 21, 22 aber auch - wie in der Zeichnung durch Antennensymbole skizziert - drahtlos mittels Funkanbindung an der Steuereinheit 5 angeschlossen sein.The trough 2 associated input device 1.1, 1.2, the functional parts (such as filling valve 9, drain valve, actuator 17, heater 18 and pump 19) of the tub and the sensors (temperature sensor 21, water level sensor 22) via control lines or signal lines 6, 23rd -27 connected to the control unit 5. Alternatively and preferably, the input device 1.1, 1.2, the functional parts 9, 12, 17, 18, 19 and the sensors 21, 22 but also - as sketched in the drawing by antenna symbols - be wirelessly connected by radio connection to the control unit 5.

An der elektronischen Steuereinheit 5 ist zudem eine Schnittstelle 28 für den Anschluss der erfindungsgemäßen Vorrichtung an ein Datenbussystem vorgesehen. Die Schnittstelle 28 ermöglicht die Integration der erfindungsgemäßen Vorrichtung in eine Gebäudesystemtechnik und damit eine Fernbedienung der Vorrichtung von beliebigen Orten in dem betreffenden Gebäude. Über das Datenbussystem können auch weitere Funktionen wie etwa die Raumtemperatur im Badezimmer eingestellt werden.In addition, an interface 28 for connecting the device according to the invention to a data bus system is provided on the electronic control unit 5. The interface 28 allows the integration of the device according to the invention in a building system technology and thus a remote control of the device from any location in the building in question. The data bus system can also be used to set other functions, such as the room temperature in the bathroom.

Ein Benutzer kann somit mittels des Eingabegerätes 1.1, 1.2 im Badezimmer als Standort der Wanne 2 oder von außerhalb des Badezimmers mittels eines am Datenbussystem angeschlossenen Bedien- und Anzeigegerätes Funktions- und/oder Programmwerte eingeben, die eingegebenen Werte benutzerbezogen speichern und die Funktionen der Wanne 2 und/oder Badeprogramme, insbesondere Sparprogramme aktivieren. So kann er beispielsweise die Badewassermenge, die Wassertemperatur, eine anfängliche Wassertemperatur, eine zu einem späteren Zeitpunkt gewünschte Wassertemperatur, die Raumtemperatur im Badezimmer, die Zudosierung von Schaumbadmitteln oder Duftstoffen relativ zur Wassermenge (Füllmenge), das Einleiten von Luft in das Badewasser, die Aktivierung bestimmter Hydromassagedüsen- oder -pumpen, die Badedauer, den Zeitpunkt und die Dauer einer Hydromassage einstellen und aktivieren.A user can thus enter function and / or program values by means of the input device 1.1, 1.2 in the bathroom as the location of the tub 2 or from outside the bathroom by means of an operating and display device connected to the data bus system, store the values entered user-specifically and the functions of the tub 2 and / or bathing programs, in particular activate savings programs. For example, he may specify the amount of bath water, the water temperature, an initial water temperature, a later desired water temperature, the room temperature in the bathroom, the addition of foam bath or fragrance relative to the amount of water (fill), the introduction of air into the bath water, activation certain hydromassage jets or pumps to set and activate the bath duration, the time and duration of a hydromassage.

Der Benutzer kann insbesondere ein seinen Vorlieben entsprechendes Badeprogramm erstellen und das Programm im Eingabegerät 1.1, 1.2 oder in der Steuereinheit 5 speichern. Die Aktivierung des Programms erfolgt vorzugsweise über die bereits erwähnte Einrichtung zur Personenerkennung oder Erfassung einer Benutzerkennung. Die gespeicherten Badeparameter werden dann automatisch eingestellt, so dass der Benutzer keine weitere Einstellung vornehmen muss.In particular, the user can create a bathing program that corresponds to his preferences and save the program in the input device 1.1, 1.2 or in the control unit 5. The activation of the program preferably takes place via the already mentioned device for recognizing persons or detecting a user identifier. The stored bath parameters are then automatically set so that the user does not have to make any further adjustments.

Mittels des elektronischen Mischventils 9 wird die gewünschte Temperatur des frisch zufließenden Wassers automatisch eingestellt. Die abgegebene Wassermenge wird dabei mittels der Durchflussmengenmesseinrichtung 12 erfasst. Gleichzeitig wird mittels eines Temperatursensors 21 die Temperatur des abgegebenen Wassers als Ist-Wert erfasst und von der elektronischen Steuereinheit 5 mit der vorgegebenen Wassertemperatur als Soll-Wert verglichen. Weicht der gemessene Ist-Wert um einen vorgebbaren Betrag vom Soll-Wert ab, so wird das elektronische Mischventil 9 entsprechend angesteuert, so dass entweder mehr warmes Wasser oder mehr kaltes Wasser zugemischt und somit der Ist-Wert dem Soll-Wert angeglichen wird.By means of the electronic mixing valve 9, the desired temperature of the freshly flowing water is automatically adjusted. The amount of water delivered is detected by means of the flow rate measuring device 12. At the same time by means of a temperature sensor 21 detects the temperature of the discharged water as the actual value and compared by the electronic control unit 5 with the predetermined water temperature as a target value. If the measured actual value deviates from the nominal value by a predeterminable amount, then the electronic mixing valve 9 is activated accordingly, so that either more warm water or more cold water is admixed and thus the actual value is adjusted to the desired value.

Der Temperatursensor 21 ist vorzugsweise am Bodenablauf bzw. Bodeneinlauf der Wanne 2 in der Ablaufgarnitur 16 angeordnet. Bei Erreichen der eingestellten Wassertemperatur wird der Wannenablauf automatisch geschlossen, indem die elektronische Steuereinheit 5 den das Ablaufventil betätigenden Stellantrieb 17 ansteuert. Es liegt allerdings auch im Rahmen der Erfindung, dass die elektronische Steuereinheit 5 den Bodenablauf bereits vor Beginn der Wasserzufuhr für das jeweilige Bad schließt, um den Wasserverbrauch zu minimieren. Da das in der Warmwasserleitung befindliche Wasser Wärmeenergie verliert, gelangt beim Öffnen des Füllventils (Mischventils) 9 üblicherweise zunächst relativ kühles Wasser aus der Warmwasserleitung 10 in die Wanne, bevor wärmeres Wasser aus dem Warmwasserkessel der Heizungsanlage des Gebäudes nachströmt. Diesbezüglich sieht eine Ausgestaltung der Erfindung vor, dass die elektronische Steuereinheit 5 das Mischverhältnis von Warmwasser und Kaltwasser nach Ablauf einer vorgegebenen oder vorgebbaren Zeit - nachdem sie das Mischventil 9 geöffnet hat - in Abhängigkeit der mittels des Temperatursensors 21 erfassten Badewassertemperatur regelt. Hierdurch können anfängliche Regelungsschwankungen bei der Einstellung der gewünschten Wassertemperatur vermieden werden. Bei der Befüllung der Wanne 2 über einen kombinierten Bodenein- und -ablauf ist die erfindungsgemäße Vorrichtung mit einem elektronischen Absperrventil oder elektronischen Rohrunterbrecher versehen. Hierdurch ist eine Rückflusssicherheit gewährleistet.The temperature sensor 21 is preferably arranged on the floor drain or bottom inlet of the tub 2 in the drain fitting 16. Upon reaching the set water temperature of the tub drain is automatically closed by the electronic control unit 5 controls the drain valve actuating actuator 17. However, it is also within the scope of the invention that the electronic control unit 5 closes the floor drain even before the start of the water supply for each bath to minimize water consumption. Since the water in the hot water line loses heat energy, when opening the filling valve (mixing valve) 9 usually comes first relatively cool water from the hot water pipe 10 into the tub before warmer water flows from the hot water boiler of the heating system of the building. In this regard, an embodiment of the invention provides that the electronic control unit 5, the mixing ratio of hot water and cold water after a predetermined or predeterminable time - after it has opened the mixing valve 9 - depending on the detected by means of the temperature sensor 21 bath water temperature regulates. This allows initial control variations in setting the desired water temperature be avoided. When filling the tub 2 via a combined floor inlet and outlet, the device according to the invention is provided with an electronic shut-off valve or electronic pipe interrupter. As a result, a return flow is guaranteed.

Wenn die Wanne 2 befüllt ist, wird mit dem Temperatursensor 21 kontinuierlich oder diskontinuierlich die Temperatur des Badewassers erfasst. Unterschreitet die Temperatur des Badewassers den vorgegebenen oder vom Benutzer gewählten Wert, so schaltet die elektronische Steuereinheit 5 die Heizeinrichtung 18 und die zugeordnete Pumpe 19 ein, um das Badewasser nachzuheizen. Erreicht das über die Pumpe 19 im Kreislauf geförderte Badewasser wieder einen bestimmten Temperaturwert, so schaltet die Steuereinheit 5 die Heizeinrichtung 18 und die Pumpe 19 wieder ab. Auf diese Weise lässt sich die Badewassertemperatur im wesentlichen Konstant halten.When the tub 2 is filled, the temperature of the bath water is continuously or discontinuously detected by the temperature sensor 21. If the temperature of the bath water falls below the predetermined or user-selected value, the electronic control unit 5 switches on the heating device 18 and the associated pump 19 in order to reheat the bathing water. If the bathwater pumped in circulation via the pump 19 again reaches a certain temperature value, the control unit 5 switches off the heating device 18 and the pump 19 again. In this way, the bath water temperature can be kept substantially constant.

Die erfindungsgemäße Vorrichtung bietet ferner einen elektronischen Überlaufschutz sowie eine elektronische Füllstandsregelung. Hierzu weist sie mindestens einen Füllstandssensor 22 auf, der über eine Signalleitung 23 oder vorzugsweise durch Funkanbindung drahtlos an der Steuereinheit 5 angeschlossen ist. Der Füllstandssensor 22 ist vorzugsweise als batterie- oder solarzellenbetriebener Zweistufensensor ausgebildet. Bei Überschreiten einer bestimmten maximalen Füllhöhe sendet der Füllstandssensor 22 ein entsprechendes Signal an die Steuereinheit 5, die dann durch Ansteuerung des elektrischen Stellantriebes 17 das Ablaufventil der Wanne 2 automatisch öffnet. Ebenso wird der Ablauf der Wanne 2 automatisch geöffnet, wenn die Füllhöhe der Wanne auf Grund der Benutzung einer Handbrause über eine bestimmte maximale Füllhöhe steigt. Bei Unterschreiten einer bestimmten Füllhöhe, wird das Ablaufventil automatisch geschlossen, sofern die über das Eingabegerät 1.1, 1.2 eingegebene Badedauer noch nicht abgelaufen ist.The device according to the invention also provides an electronic overflow protection and an electronic level control. For this purpose, it has at least one fill level sensor 22 which is wirelessly connected to the control unit 5 via a signal line 23 or preferably by radio connection. The level sensor 22 is preferably designed as a battery or solar cell operated two-stage sensor. When a certain maximum fill level is exceeded, the fill level sensor 22 sends a corresponding signal to the control unit 5, which then automatically opens the drain valve of the trough 2 by actuating the electric actuator 17. Likewise, the flow of the tub 2 is automatically opened when the Due to the use of a hand shower, the filling height of the tub rises above a certain maximum filling level. When falling below a certain level, the drain valve is automatically closed, provided that the input via the input device 1.1, 1.2 bath duration has not yet expired.

Die ordnungsgemäße Funktion des Füllstandssensors 22 wird durch die elektronische Steuereinheit 5 überwacht. Erfasst die Steuereinheit 5 eine Fehlfunktion der Füllstandssensorik, so unterbindet sie eine Befüllung der Wanne 2. Eine Ansteuerung des Füllventils 9 unterbleibt dann solange bis die Füllstandssensorik wieder fehlerfrei funktioniert.The proper functioning of the level sensor 22 is monitored by the electronic control unit 5. Detects the control unit 5 a malfunction of the level sensor, so it prevents a filling of the tub 2. A control of the filling valve 9 is then omitted until the level sensor system works correctly again.

Vielmehr sind zahlreiche Varianten möglich. So kann die erfindungsgemäße Vorrichtung beispielsweise auch bei einer Badewanne mit Whirlpooltechnik verwendet werden.The embodiment of the device according to the invention is not limited to the embodiments described above with reference to the drawings. Rather, numerous variants are possible. For example, the device according to the invention can also be used in a bathtub with a whirlpool technology.

Alternativ zu der Wannenzulaufarmatur 14 kann die erfindungsgemäße Vorrichtung auch eine kombinierte Zu- und Ablaufgarnitur aufweisen. In diesem Fall erfolgt die Befüllung der Wanne über einen Bodeneinlauf.As an alternative to the pan inlet fitting 14, the device according to the invention may also have a combined inlet and outlet fitting. In this case, the tank is filled via a bottom drain.

Zusätzlich zu dem im Wannenkörper 2 integrierten Eingabegerät 1.1 bzw. dem externen, fest montierbaren Eingabegerät 1.2 kann die erfindungsgemäße Vorrichtung auch noch über einen optionalen Handsender oder eine entsprechende mobile, kabellose Fernbedienung bedient werden.In addition to the integrated in the bath body 2 input device 1.1 or the external, permanently mountable input device 1.2, the inventive device can also be operated via an optional remote control or a corresponding mobile wireless remote control.

Die vorliegende Erfindung bietet höchsten Komfort, eine hohe Bedienfreundlichkeit bei der Steuerung verschiedener Funktionen einer Bade- oder Whirlpoolwanne sowie eine wirtschaftliche Befüllung hinsichtlich Energieeffizienz und Wassersparaspekten. Die Badewassertemperatur lässt sich mit der erfindungsgemäßen Vorrichtung frei und stufenlos einstellen. Durch das elektronisch gesteuerte Füllventil (Mischventil) 9 der Vorrichtung wird eine präzise Wassermengenabgabe erzielt. Die Erfindung bietet insbesondere beim Befüllen der Wanne 2 einen sicheren Schutz vor einem Überlauf über den Wannenrand. Sie bietet ferner einen Abkühlschutz des Wannenwassers durch geregeltes Nachheizen auf eine vorwählbare Wassertemperatur.The present invention offers the highest level of comfort, a high degree of user-friendliness in the control of various functions of a bath or spa tub as well as economical filling in terms of energy efficiency and water saving aspects.
