Description

SANITÄRANLAGE MIT KOMMUNIKATIONSEINHEITEN UND SENSORARMATUR  SANITARY SYSTEM WITH COMMUNICATION UNITS AND SENSOR ARMATURE
Die Erfindung betrifft eine Sanitäranlage gemäß dem Oberbe- 5 griff des Patentanspruchs 1. The invention relates to a sanitary installation according to the upper handle 5 of the patent claim. 1
Eine Sanitäranlage der eingangs genannten Art ist allgemein bekannt, so dass es insofern keines besonderen druckschriftlichen Nachweises bedarf. Eine solche Anlage besteht aus einer 10 stromversorgten Sensorarmatur zur Durchführung einer Hygienespülung mit einer ersten signalverarbeitenden Kommunikations - einheit und einem elektrisch betätigbaren und ohne Bestromung automatisch schließenden Ventil mit einer zweiten signalverarbeitenden Kommunikationseinheit und einer Stromversorgung, wo- 15 bei die Sensorarmatur und das Ventil fluidisch über eine Wasserleitung und die beiden Kommunikationseinheiten informationell miteinander verbunden ausgebildet sind. A sanitary facility of the type mentioned is well known, so that it requires no special documentary proof insofar. Such a system consists of a power-supplied sensor fitting for carrying out a hygiene flushing with a first signal-processing communication unit and an electrically actuated and automatically closing without energization valve with a second signal-processing communication unit and a power supply, 15 in the sensor armature and the valve fluidly via a water pipe and the two communication units are formed informationally connected to each other.
Unter einer Sensorarmatur ist dabei hier und auch im Folgenden 20 stets eine Wasserarmatur zu verstehen, die ein elektrisch betätigbares Absperrventil aufweist, um den Abfluss von Wasser aus der Wasserleitung über die Armatur zu steuern. Dabei wird das Absperrventil bevorzugt (aber nicht ausschließlich) durch eine Steuerung betätigt, welche die Signale eines (in der 25 Regel optisch arbeitenden) Sensors verarbeitet. Under a sensor fitting is here and in the following 20 always a water valve to understand that has an electrically actuated shut-off valve to control the outflow of water from the water pipe through the valve. In this case, the shut-off valve is preferably (but not exclusively) actuated by a controller, which processes the signals of a (optically operating in the rule 25) sensor.
Die Maßgabe, dass die Sensorarmatur stromversorgt ist, geht dabei hier und im Folgenden davon aus, dass die Sensorarmatur wie üblich mit einer Batterie, einem Akkumulator oder derglei- 30 chen ausgerüstet ist. In Betracht kommt aber auch eine netzgebundene Stromversorgung, wobei diese dann aber unabhängig von der nachfolgend genannten Stromversorgung des Ventils sein muss . The proviso that the sensor armature is supplied with power here and in the following assumes that the sensor armature is equipped, as usual, with a battery, an accumulator or the like. In addition, but also comes a network-based power supply, but this then independent of must be the below-mentioned power supply of the valve.
Unter einem elektrisch betätigbaren Ventil ist dabei hier und auch im Folgenden stets ein solches Ventil zu verstehen, das 5 elektrisch geöffnet bzw. geschlossen wird. Hierzu ist das Ventil mit der oben genannten Stromversorgung versehen, die allerdings unterbrochen wird, wenn zum Beispiel die Hauptsicherung eines Gebäudes, einer Etage oder einer sonstigen Einheit abgeschaltet wird. 10 Under an electrically actuated valve is here and in the following always such a valve to understand that 5 is electrically opened or closed. For this purpose, the valve is provided with the above-mentioned power supply, but this is interrupted when, for example, the main fuse of a building, a floor or other unit is turned off. 10
Unter einer signalverarbeitenden Kommunikationseinheit ist dabei hier und auch im Folgenden stets eine solche aus elektronischen Bauteilen bestehende Einheit zu verstehen, die einerseits Signale verarbeiten andererseits aber auch zum In- 15 formationsaustausch mit anderen Einheiten per Funk oder dergleichen kommunizieren kann. A signal-processing communication unit here and in the following always means such a unit consisting of electronic components which, on the one hand, processes signals, on the other hand, can also communicate with other units by radio or the like for information exchange.
Unter der oben genannten Hygienespülung ist dabei ferner eine Maßnahme zu verstehen, bei der in vordefinierten Abständen die 20 Sensorarmatur automatisch geöffnet wird, um eine Stagnation des in der Wasserleitung befindlichen Wassers und damit zum Beispiel eine unerwünschte Keimbildung auszuschließen (gemäß der aktuellen Fassung der Trinkwasserverordnung) . Praktisch bedeutet dies, dass die Sensorarmatur, von der natürlich auch 25 mehrere vorhanden sein können, mit der signalverarbeitenden Kommunikationseinheit versehen ist, die zum Beispiel alle 72 Stunden die Sensorarmatur öffnet, um eine bestimmte Menge an Wasser abfließen zu lassen. Under the above-mentioned hygiene flush is also a measure to understand in which the sensor armature is automatically opened at predefined intervals to exclude a stagnation of the water in the water pipe and thus, for example, an undesirable nucleation (according to the current version of the Drinking Water Ordinance) , In practical terms, this means that the sensor fitting, of which several can of course also be present, is provided with the signal-processing communication unit which, for example, opens the sensor fitting every 72 hours in order to allow a certain amount of water to drain off.

Der Erfindung liegt die Aufgabe zugrunde, eine Sanitäranlage der eingangs genannten Art zu verbessern. Insbesondere soll eine Sanitäranlage - und dies gilt sowohl für Bestandsanlagen als auch für Neuanlagen - geschaffen werden, die auch dann funktioniert, wenn die Stromversorgung des Ventils unterbrochen ist. The invention has for its object to improve a sanitary system of the type mentioned. In particular, should Sanitation - and this applies to both existing and new installations - created, which also works when the power supply to the valve is interrupted.

Diese Aufgabe ist mit einer Sanitäranlage der eingangs genannten Art durch die im Kennzeichen des Patentanspruchs 1 aufgeführten Merkmale gelöst. This object is achieved with a sanitary system of the type mentioned by the features listed in the characterizing part of patent claim 1.
Nach der Erfindung ist also vorgesehen, dass zur Gewährleis- 10 tung einer Hygienespülung bei abgeschalteter Stromversorgung die Wasserleitung mit einem mit der ersten Kommunikationseinheit verbundenen Drucksensor und das Ventil mit einer Zusatzstromversorgung versehen ist. According to the invention, it is thus provided that in order to ensure a hygiene flushing when the power supply is switched off, the water line is provided with a pressure sensor connected to the first communication unit and the valve with an additional power supply.

Mit anderen, verfahrensmäßigen Worten ausgedrückt, zeichnet sich die erfindungsgemäße Sanitäranlage somit insbesondere dadurch aus, dass mit Hilfe des zur Messung des Leitungswasserdrucks ausgebildeten Drucksensors ein auf ein Öffnen der Sensorarmatur zurückgehender Druckabfall ermittelt und bei abge- 20 schalteter Stromversorgung des Ventils bei Vorliegen eines solchen Druckabfalls mit Hilfe der Zusatzstromversorgung das Ventil geöffnet wird. In other words, in terms of procedural words, the sanitary system according to the invention is thus characterized in particular by determining a pressure drop due to opening of the sensor fitting with the aid of the pressure sensor designed to measure the tap water pressure and with a switched off power supply of the valve in the presence of such a pressure drop with the help of the auxiliary power supply, the valve is opened.
Wie weiter unten noch genauer erläutert wird, kann der Druck- 25 sensor dabei unmittelbar mit der ersten Kommunikationseinheit oder auch mittelbar über eine eigene, dritte Kommunikations- einheit mit der ersten Kommunikationseinheit verbunden sein. Entscheidend ist, dass die an der Sensorarmatur und am Drucksensor vorliegenden Informationen ausgewertet werden und aus 30 dieser Basis über das Öffnungen und Schließen des Ventils entschieden werden kann. Andere vorteilhafte Weiterbildungen der erfindungsgemäßen Sanitäranlage ergeben sich aus den abhängigen Patentansprüchen. As will be explained in more detail below, the pressure sensor can be connected directly to the first communication unit or also indirectly via its own third communication unit to the first communication unit. The decisive factor is that the information present at the sensor fitting and at the pressure sensor is evaluated and it is possible to decide on the opening and closing of the valve. Other advantageous developments of the sanitary installation according to the invention will become apparent from the dependent claims.
Der Vollständigkeit halber wird noch auf das Dokument EP 2 700 5 756 AI hingewiesen, aus dem ebenfalls eine Sanitäranlage bekannt ist, bei der aber das elektrisch betätigbare Ventil bei Stromabschaltung nicht automatisch schließt, was den Nachteil mit sich bringt, dass die zur Sensorarmatur führende Leitung immer unter Wasserdruck steht, d.h. bei einem Bruch dieser 10 Wasserleitung ist mit hoher Wahrscheinlichkeit mit einem Wasserschaden zu rechnen. For the sake of completeness, reference is still made to the document EP 2 700 5 756 AI, from which also a sanitary system is known, but in which the electrically actuated valve does not automatically close at power off, which has the disadvantage that the leading to the sensor armature line always under water pressure, ie a break of this 10 water pipe is likely to cause water damage.
Ferner wird noch auf die Lösung gemäß dem nachveröffentlichten Dokument DE 10 2015 121 547 AI hingewiesen, bei der aber ins- 15 besondere der im Patentanspruch 1 genannte Drucksensor fehlt. Furthermore, attention is drawn to the solution according to the subsequently published document DE 10 2015 121 547 A1, but in particular the pressure sensor mentioned in patent claim 1 is missing.
Außerdem wird der Vollständigkeit halber auf das im Paral- lelanmeldeverfahren ermittelte, weiter abliegende Dokumente FR 2 835 033 AI hingewiesen. 20 In addition, for the sake of completeness, reference is made to the more extensive documents FR 2 835 033 AI, which have been found in the parallel application procedure. 20
Die erfindungsgemäße Sanitäranlage einschließlich ihrer vorteilhaften Weiterbildungen gemäß der abhängigen Patentansprüche wird nachfolgend anhand der zeichnerischen Darstellung zweier Ausführungsbeispiele näher erläutert. 25 The sanitary system according to the invention, including its advantageous developments according to the dependent claims will be explained in more detail with reference to the drawing representation of two embodiments. 25
Es zeigt schematisch It shows schematically
Figur 1 die erfindungsgemäße Sanitäranlage mit einem direkt Figure 1, the sanitary system according to the invention with a direct
mit der ersten Kommunikationseinheit verbundenen 30 Drucksensor; und Figur 2 ein zweites Ausführungsbeispiel, bei dem der Drucksensor eine eigene Kommunikationseinheit aufweist. 30 pressure sensor connected to the first communication unit; and 2 shows a second embodiment in which the pressure sensor has its own communication unit.
Die in den Figuren 1 und 2 dargestellte Sanitäranlage besteht in bekannter Weise aus einer stromversorgten Sensorarmatur 1 5 zur Durchführung einer Hygienespülung mit einer ersten signalverarbeitenden Kommunikationseinheit 1.1, die wahlweise von der Stromversorgung der Sensorarmatur 1 mit Strom versorgt wird oder sogar eine eigene Stromversorgung (wie zum Beispiel eine Batterie oder einen Akkumulator) aufweist, und einem 10 elektrisch betätigbaren und ohne Bestromung automatisch schließenden Ventil 2 mit einer zweiten signalverarbeitenden Kommunikationseinheit 2.1 und einer Stromversorgung 2.2, wobei die Sensorarmatur 1 und das Ventil 2 über eine Wasserleitung 3 fluidisch und die beiden Kommunikationseinheiten 1.1, 2.1 in- 15 formationeil miteinander verbunden ausgebildet sind. The sanitary installation shown in Figures 1 and 2 consists in a known manner from a powered sensor fitting 1 5 for carrying out a hygiene flush with a first signal processing communication unit 1.1, which is optionally powered by the power supply of the sensor fitting 1 with electricity or even its own power supply (such as Example, a battery or an accumulator), and a 10 electrically actuated and without energization automatically closing valve 2 with a second signal processing communication unit 2.1 and a power supply 2.2, wherein the sensor fitting 1 and the valve 2 via a water pipe 3 fluidly and the two communication units 1.1 2.1 2.1 are formed connected together.
Weiterhin ist, wenn auch nicht extra dargestellt, in an sich bekannter Weise zur Stromversorgung der Sensorarmatur 1 ein vorzugsweise aufladbarer elektrischer Energiespeicher (insbe- 20 sondere Akkumulator) vorgesehen, d.h. die Sensorarmatur 1 erhält die für ihre Funktion erforderliche Energie aus diesem Energiespeicher. Eine elektrische Verbindung mit der Stromversorgung des Gebäudes ist in der Regel wegen des damit verbundenen großen Aufwandes nicht vorgesehen bzw. nicht vorhanden. 25 Furthermore, although not shown separately, a preferably rechargeable electrical energy store (in particular rechargeable battery) is provided in a manner known per se for supplying power to the sensor fitting 1, i. the sensor fitting 1 receives the energy required for its function from this energy store. An electrical connection to the power supply of the building is usually not provided or not available because of the associated great expense. 25
Noch etwas genauer betrachtet, ist die Sensorarmatur 1 in ebenfalls bekannter Weise mit einem mit der Wasserleitung 3 wirkverbundenen Absperrventil 1.2 versehen, wobei dieses über eine entsprechende Lichtschranke oder dergleichen elektrisch betätigbar ausgebildet ist und die Energie aus dem genannten Energiespeicher verwendet wird, um es im Bedarfsfall, also zum Beispiel, wenn sich ein Benutzer die Hände waschen möchte, zu betätigen . Considered in more detail, the sensor fitting 1 is also provided in a known manner with a valve connected to the water pipe 3 shut-off valve 1.2, which is electrically actuated via a corresponding light barrier or the like and the energy is used from said energy storage to it in case of need , so to For example, when a user wants to wash their hands, press.
Wesentlich für die erfindungsgemäße Sanitäranlage ist nun, und dies gilt für alle beliebigen Ausführungsformen, dass zur 5 Gewährleistung einer Hygienespülung bei abgeschalteter Stromversorgung 2.2 die Wasserleitung 3 mit einem mit der ersten Kommunikationseinheit 1.1 verbundenen Drucksensor 4 und das Ventil 2 mit einer Zusatzstromversorgung 2.3 versehen ist. It is essential for the sanitary installation according to the invention, and this applies to all embodiments, that the water pipe 3 is provided with a pressure sensor 4 connected to the first communication unit 1.1 and the valve 2 is provided with an additional power supply 2.3 for ensuring a hygiene flush with the power supply 2.2 disconnected.
10 10
Die genannte Zusatzstromversorgung 2.3 ist dabei besonders bevorzugt wahlweise als elektrischer Energiespeicher (einfach als Batterie) und/oder bei bei eingeschalteter Stromversorgung 2.2 von dieser (wieder-) aufladbar (also als Akkumulator) ausgebildet. 15 Said additional power supply 2.3 is particularly preferably either as an electrical energy storage (simply as a battery) and / or when the power supply 2.2 of this (re) rechargeable (ie as an accumulator) is formed. 15
Bezüglich der Positionierung des Drucksensors 4 ist bevorzugt vorgesehen, dass dieser näher an der Sensorarmatur 1 als am Ventil 2 angeordnet ist. Noch etwas genauer betrachtet, aber nicht extra dargestellt, ist besonders bevorzugt vorgesehen, 20 dass die Sensorarmatur 1 oberhalb eines Waschbeckens und der Drucksensor 4 unterhalb dieses Waschbeckens an der Wasserleitung 3 angeordnet ist. Alternativ kann schließlich auch vorgesehen sein, dass der Drucksensor 4 in der Sensorarmatur 1 angeordnet ist. 25 With regard to the positioning of the pressure sensor 4, it is preferably provided that it is arranged closer to the sensor fitting 1 than to the valve 2. Considered in more detail, but not shown separately, is particularly preferably provided 20 that the sensor fitting 1 above a wash basin and the pressure sensor 4 is disposed below the wash basin to the water pipe 3. Alternatively, it can finally also be provided that the pressure sensor 4 is arranged in the sensor fitting 1. 25
Wie in den Figuren 1 und 2 dargestellt, ist ferner bevorzugt vorgesehen, dass die erste signalverarbeitende Kommunikations - einheit 1.1 und die zweite signalverarbeitende Kommunikations- einheit 2.1 drahtlos miteinander kommunizierend ausgebildet 30 sind. Bei der Lösung gemäß Figur 1 ist dabei der Drucksensor 4, wie ersichtlich, direkt (zum Beispiel über ein Kabel) mit der ersten Kommunikationseinheit 1.1 verbunden. Bei der Lösung gemäß Figur 2 weist der Drucksensor 4 eine dritte, mit der ersten informationell verbundene, signalverarbeitende Kommunikations- 5 einheit 4.1 auf, wobei weiterhin besonderes bevorzugt vorgesehen ist, dass (auch) die dritte signalverarbeitende Kommunikationseinheit 4.1 drahtlos kommunizierend ausgebildet ist. As shown in FIGS. 1 and 2, it is further preferably provided that the first signal-processing communication unit 1.1 and the second signal-processing communication unit 2.1 are configured to communicate with each other wirelessly. In the solution according to FIG. 1, the pressure sensor 4, as can be seen, is connected directly (for example via a cable) to the first communication unit 1.1. In the solution according to Figure 2, the pressure sensor 4, a third, with the first informationally connected, signal processing communication unit 5 4.1, wherein further particularly preferred is provided that (also) the third signal processing communication unit 4.1 is formed wirelessly communicating.
Nur der Vollständigkeit halber, weil an sich selbstverständ- 10 lieh, wird noch darauf hingewiesen, dass die Kommunikations - einheiten 1.1, 2.1, 4.1 (sofern vorhanden) aus Hard- und Software bestehend ausgebildet sind. For the sake of completeness, because it is self-evident, it should be pointed out that the communication units 1.1, 2.1, 4.1 (if present) are made up of hardware and software.
Die erfindungsgemäße Sanitäranlage funktioniert wie folgt: 15 The sanitary installation according to the invention functions as follows: 15
Ausgangspunkt der nachfolgenden Erläuterung ist zum Beispiel der Donnerstagabend vor Ostern, an dem in einer Zahnarztpraxis typischer Weise der Hauptstromschalter ausgeschaltet wird, um die sensiblen Praxisgeräte vor einem Stromschlag oder derglei- 20 chen während der Feiertage zu schützen. Diese Stromabschaltung hat dabei zur Folge, dass auch das als Hauptventil der Praxis ausgebildete Ventil 2 nicht mehr mit Strom versorgt wird, mithin also automatisch schließt, was auch gewünscht ist, da man zusätzlich die Praxis während der Feiertage gerne vor unge- 25 wolltem Wassereinbruch schützen möchte. The starting point for the following explanation is, for example, the Thursday evening before Easter, at which the main power switch is typically switched off in a dental practice in order to protect the sensitive practice devices from electric shock or the like during the holidays. This power cutoff has the consequence that also designed as the main valve of practice valve 2 is no longer supplied with power, thus therefore automatically closes, which is also desirable because you also practice during the holidays like to protect against unwanted flooding would like to.
Ist aber das Ventil 2 geschlossen, würde ein typischer Weise nach 72 Stunden seit ihrer letzten Benutzung von der Sensorarmatur 1 initiierter Versuch einer Hygienespülung ins Leere 30 laufen, da der Sensorarmatur 1 kein Wasser zur Verfügung steht . Dank des erfindungsgemäßen Drucksensors 4 ist es nunmehr aber möglich, trotzdem eine Hygienespülung durchführen zu lassen, und zwar, weil - verfahrensmäßig ausgedrückt - vorgesehen ist, dass mit Hilfe des Drucksensors 4 ein auf ein Öffnen der Sen- 5 sorarmatur 1 zurückgehender Druckabfall ermittelt und bei abgeschalteter Stromversorgung des Ventils 2 bei Vorliegen eines solchen Druckabfalls mit Hilfe der Zusatzstromversorgung 2.3 das Ventil 2 - trotz abgeschaltetem Hauptstromschalter - geöffnet wird. Hierbei ist natürlich vorgesehen, dass auch die 10 zweite Kommunikationseinheit 2.1 wahlweise mit der Zusatzstromversorgung 2.3 verbunden ist oder sogar eine eigene (nicht extra dargestellte) Stromversorgung aufweist. However, if the valve 2 is closed, a test of a hygiene flush initiated by the sensor fitting 1 would typically run out of space 30 after 72 hours since its last use, since no water is available to the sensor fitting 1. Thanks to the pressure sensor 4 according to the invention, it is now possible, however, to have a hygiene flush carried out, specifically because, as expressed in terms of the method, a pressure drop originating from an opening of the sensor 5 is determined with the aid of the pressure sensor 4 and at disconnected power supply of the valve 2 in the presence of such a pressure drop by means of the auxiliary power supply 2.3, the valve 2 - despite the main power switch is switched off - is opened. It is of course provided that the second communication unit 2.1 is also optionally connected to the additional power supply 2.3 or even has its own (not shown separately) power supply.
Ist also nach einer letzten Betätigung der Sensorarmatur 1 15 eine gewisse, vorgegebene Zeit (wie oben bereits erwähnt, typischer Weise 72 Stunden) vergangen, so ist vorgesehen, dass die Sensorarmatur 1 geöffnet wird bzw. sich selbsttätig öffnet, wenn ein vom Drucksensor 4 gemessener Druck innerhalb eines vorgegebenen bzw. des oben erwähnten Zeitraums einen er- 20 sten, vorgegebenen Druck nicht unterschreitet. Als Druckwert wird hier typischer Weise derjenige Druck hinterlegt, der in der Wasserleitung bei geöffnetem Ventil 2 (Hauptventil), aber geschlossener Sensorarmatur 1 herrscht, wenn also Wasser an der Sensorarmatur 1 ansteht, aber nicht abfließt. 25 Thus, after a last actuation of the sensor fitting 15, a certain, predetermined time (as already mentioned above, typically 72 hours) has elapsed, it is provided that the sensor fitting 1 is opened or automatically opens when a pressure sensor 4 measures it Pressure within a given or the above-mentioned time period does not fall below a first, predetermined pressure. The pressure value is here typically stored that pressure which prevails in the water pipe with the valve 2 open (main valve), but closed sensor fitting 1, so if water is present at the sensor fitting 1, but does not drain. 25
Im nächsten Schritt, also bei bereits geöffneter Sensorarmatur 1, wird dann das Ventil 2 geöffnet, wenn ein vom Drucksensor 4 gemessener Druck einen zweiten, vorgegebenen Druck unterschreitet, wobei hierbei gilt, dass der erste, vorgegebene 30 Druck größer als der zweite vorgegebene Druck ist, wobei als zweiter Druckwert typischer derjenige Druck hinterlegt wird, der in der Wasserleitung bei geöffneter Sensorarmatur 1 und geöffnetem Ventil 2 herrscht, wenn also vom Hauptventil kommendes Wasser über die Sensorarmatur 1 abfließt. In the next step, that is to say with the sensor fitting 1 already opened, the valve 2 is then opened when a pressure measured by the pressure sensor 4 falls below a second, predetermined pressure, in which case the first predetermined pressure is greater than the second predetermined pressure , wherein as the second pressure value more typically that pressure is stored, which prevails in the water pipe when the sensor fitting 1 is open and the valve 2 is open, that is to say when water coming from the main valve flows out via the sensor fitting 1.
Bei alledem ist ferner bei Vorhandensein des oben bereits er- 5 wähnten Absperrventils 1.2 vorgesehen, dass eine Information über eine Stellung des Absperrventils 1.2 an die erste signalverarbeitende Kommunikationseinheit 1.1 übertragen wird. Moreover, in the presence of the above-mentioned shut-off valve 1.2, it is further provided that information about a position of the shut-off valve 1.2 is transmitted to the first signal-processing communication unit 1.1.
Wurde die Hygienespülung schlussendlich durchgeführt, wird 10 schließlich das Ventil 2 - entsprechend von der Sensorarmatur 1 über die Kommunikationseinheiten 1.1, 2.1 informiert - wieder stromlos geschaltet, sprich geschlossen. Die gesamte Anlage befindet sich dann wieder in dem Zustand, wie sie am Donnerstag vor Ostern zurückgelassen wurde, nur mit dem Unter- 15 schied, dass die regelmäßig durchzuführende Hygienespülung tatsächlich durchgeführt wurde und sich die gesamte Sanitäranlage somit in einem einwandfreien Zustand befindet. Finally, if the hygiene flushing has been carried out, the valve 2 is finally switched off, ie closed, in accordance with the information provided by the sensor fitting 1 via the communication units 1.1, 2.1. The entire system is then back in the same condition as it was left on Thursday before Easter, only with the difference that the regular hygiene flushing was actually carried out and the entire sanitary facility is thus in perfect condition.
