Abstract

Hot water tank with heating which is controlled by the temperature of the stored water by means of a thermostat which is arranged in the central or upper region of the storage space and monitors the temperature of the service water to be drawn, and of a thermostat which is arranged in the bottom region of the storage space and monitors falling below a temperature limit value in this bottom region. The lower thermostat (11) is connected to a timer which only switches on heating of the stored water when heating controlled by the thermostat (10) arranged in the central or upper region of the storage space (3) has not taken effect within a predetermined period of time.

WarmwasserspeicherHot water tank

Die Erfindung betrifft einen Warmwasserspeicher mit einer vor der Temperatur des Speicherwassers mittels eines im mittleren oder oberen Bereich des Speicherraums angeordneten, die Temperatur des zu zapfenden Brauchwassers überwachenden Thermostaten, und eines 1m frodenbereich des Speicherraums angeordneten, die Unterschreitung eines Temperaturgrenzwertes in diesem Bodenbereich überwachenden Thermostaten gesteuerten Beheizung.The invention relates to a hot water storage tank with a heating system controlled by means of a thermostat arranged in the middle or upper area of the storage space, which monitors the temperature of the domestic water to be drawn off, and a thermostat arranged 1 m below the floor of the storage space, which monitors the undershooting of a temperature limit value in this floor area.

Ein solche. Warmwasserspeicher 1st bekanntgeworden aus der DE-OS 3 346 513. Hler findet zur Beheizung des Speichers eine Wärmepumpe Anwendung, und zwischen den beiden Fühlern wird umgeschaltet, um entweder bei geringem Warmwisserbedarf eine kleine Wassermenge hoher Temperatur oder bei großem Wasserbedarf eine gesteigerte Menge erwärmten Wassers bereitstellen zu können.Such a hot water storage tank is known from DE-OS 3 346 513. A heat pump is used to heat the storage tank, and switching is carried out between the two sensors in order to be able to provide either a small amount of water at a high temperature when there is a low demand for hot water or an increased amount of heated water when there is a high demand for water.

Aus der DE-OS 2 923,488«jist"eiiH'jgas6ehe^zter Warmwasserspeicher bekanntgeworden,'dat*'sxfw'oh.l*Brauchwasser speichern kann als auch Wärme an das Umlaufwasser einer Heizungsanlage abgeben kann.From DE-OS 2 923,488 a gas-heated hot water storage tank has become known which can store domestic water and also release heat to the circulating water of a heating system.

Um letzteres zu bewerkstelligen, ist der Motor einer Umwälzpumpe des Heizungssystems von einem Temperaturfühler beaufschlagt, der den Innenraum des Speichers abfiihlt. Daneben ist ein zweiter Temperaturfühler vorhanden, der die Beheizung des Speichers steuert.To achieve the latter, the motor of a circulation pump in the heating system is actuated by a temperature sensor that senses the interior of the storage tank. There is also a second temperature sensor that controls the heating of the storage tank.

Schließlich ist aus der DE-OS 3 310 023 ein direkt beheizter Warmwasserspeicher bekanntgeworden, bei d'ii drei Temperaturfühler vorgesehen sind, die in Verbindung mit einem Feuerungsautomaten die Beheizung des Speichers steuern.Finally, DE-OS 3 310 023 discloses a directly heated hot water storage tank in which three temperature sensors are provided which, in conjunction with an automatic firing system, control the heating of the storage tank.

Es ist Aufgabe der vorliegenden Erfindung,It is the object of the present invention

den Bodenbereich des Heißwasserspeichers, der durch das einströmende Kaltwasser bei Brauchwasserzapfung häufig kühl wird beziehungsweise sich nicht ausreichend erwärmt, von Zeit zu Zeit auf eine höhere Temperatur aufzuheizen, um die Vermehrung der die sogenannte Legionärskrankheit verursachenden Bakterien zu unterbinden. the bottom area of the hot water tank, which often gets cold or does not heat up sufficiently due to the cold water flowing in when domestic water is drawn, should be heated to a higher temperature from time to time in order to prevent the proliferation of the bacteria that cause Legionnaires' disease.

Die Lösung der Aufgabe erfolgt erfindungsgemäß dadurch, daß der 'jntere Thermostat mit einem Zeitglied gekoppelt ist, das eine Beheizung des Speicherwassers nur dann einschaltet, wenn innerhalb einer vorgegebenen ZeitspanneThe solution to the problem is achieved according to the invention in that the inner thermostat is coupled to a timer that only switches on heating of the storage water if within a predetermined time period

Durch diese Ausgestaltung 1st es möglich, innerhalb wählbarer Zeiträume abzufragen, ob der Speicher nachgeheizt wurde. Ist dies nicht geschehen, so wird über das Zeltglied die Beheizung so freigegeben, daß der gesamte Speicherinhalt auf eine die Abtötung der Bakterien gewährleistende Temperatur aufgeheizt wird.This design makes it possible to check within selectable time periods whether the storage tank has been reheated. If this has not happened, the heating is released via the tent element so that the entire storage tank contents are heated to a temperature that ensures that the bacteria are killed.

Dia einzige Zeichnungsfigur stellt in einem schematischen Vertikalschnitt einen Speicherbehälter 1 mit einem Doppelboden 2 dar. In den Speicherraum 3 dieses Speicherbehälters 1 mündet die Vor 1 aufleitung 4 eines nicht dargestellten brennerbeheizten Wasserheizers, dessen Heißwasser den Speicherraum 3 zum Aufheizen des Speicherw^ssers in einer Wendel 5 durchströmt und sodann in der die Speicherdecke 6 durchsetzenden Rücklaufleitung 7 zum Wasserheizer zurückströmt. Eine Kaitwasser&zgr;ufuhrleitung 8 durchsetzt ebenfalls die Speicherdecke 6 und mündet in den Bodenbereich des Speicherr umes 3. Eine Brauchwasserzäpfleitung 9 geht von der Speicherdecke 6 aus.The only drawing figure shows a storage tank 1 with a double bottom 2 in a schematic vertical section. The supply line 4 of a burner-heated water heater (not shown) opens into the storage space 3 of this storage tank 1, the hot water of which flows through the storage space 3 in a coil 5 to heat the storage water and then flows back to the water heater in the return line 7 which passes through the storage ceiling 6. A cold water supply line 8 also passes through the storage ceiling 6 and opens into the floor area of the storage space 3. A service water tap line 9 starts from the storage ceiling 6.

Zur überwachung dar Temperatur des zu zapfenden Brauchwassers ist - wie üblich - ein Thermostat 10 im mittleren oder oberen Bereich des Speicherraumes 3 angeordnet. Bei Unterschreitung eines Temperaturgrenzwertes schaltet er die Beheizung des Speicherwassers durch das die Wendel 5To monitor the temperature of the domestic water to be drawn, a thermostat 10 is - as usual - arranged in the middle or upper area of the storage room 3. If a temperature limit is undershot, it switches on the heating of the storage water by the coil 5

Der untere zusätzliche Thermostat 11 1m Bodenbereich so^gt hingegen dafür, daß die Wassertemperatur 1n diesem Bodenbereich nicht auf allzulange, eine Entwicklung von Kleinstlebewesen ermöglichende Dauer unterhalb eines die Entwicklung ermöglichenden Grenzwert absinkt. Zu diesem Zweck kann dieser Thermostat 11 mit einem Zeltglied gekoppelt werden, das eine von diesem Thermostaten 11 gesteuerte Beheizung des Speicherwassers nur dann veranlaßt, wenn innerhalb einer vorgegebenen Zeitspanne keine durch den oberen Thermostaten 10 gesteuerte Beheizung eingetreten ist.The lower additional thermostat 11 in the bottom area, on the other hand, ensures that the water temperature in this bottom area does not fall below a limit value that allows the development of microorganisms for too long. For this purpose, this thermostat 11 can be coupled to a tent element that only initiates heating of the storage water controlled by this thermostat 11 if no heating controlled by the upper thermostat 10 has occurred within a predetermined period of time.

Durch dieses Zusammenwirken der beiden Thermostaten 10 und 11 werden demnach für die Entwicklung von Kleinstlebewesen eforderliche Mindestverwei1 zeiten , in denen die Temperatur den für die Keimtötung erforderlichen Mindestwert unterschreitet, zuverlässig vermieden.This interaction of the two thermostats 10 and 11 reliably avoids the minimum dwell times required for the development of microorganisms, during which the temperature falls below the minimum value required for germ killing.
