Die Erfindung betrifft einen Warmwasserspeicher mit einem entweder im mittleren oder oberen Bereich des Speicherraums angeordneten, die Temperatur des zu zapfenden Brauchwassers überwachenden Thermostaten, und einen im Bodenbereich des Speicherraums angeordneten, die Unterschreitung eines Temperaturgrenzwertes in diesem Bodenbereich überwachenden Thermostaten, welche die Erwärmung steuern. S Ein solcher Warmwasserspeicher ist bekanntgeworden aus der DE-OS 3 346 513. Hier findet zur Beheizung des Speichers eine Wärmepumpe Anwendung, und zwischen den beiden Fühlern wird umgeschaltet, um entweder bei geringem Warmwasserbedarf eine kleine Wassermenge hoher Temperatur oder bei großem Wasserbedarf eine gesteigerte Menge erwärmten Wassers bereitstellen zu können.The invention relates to a hot water tank with a thermostat arranged either in the middle or upper area of the storage space, which monitors the temperature of the domestic water to be drawn, and a thermostat arranged in the floor area of the storage space, which monitors the temperature in this floor area and which controls the heating. S Such a hot water tank has become known from DE-OS 3 346 513. Here, a heat pump is used to heat the tank, and a switch is made between the two sensors in order to either use a small amount of water at a high temperature when the hot water requirement is low or an increased amount when the water requirement is high to provide heated water.
Aus der DE-OS 2 923 488 ist ein gasbeheizter Warmwasserspeicher bekanntgeworden, der sowohl Brauchwas-10 ser speichern kann als auch Wärme an das Umlaufwasser einer Heizungsanlage abgeben kann.From DE-OS 2 923 488 a gas-heated hot water tank has become known, which can both store hot water and can also give off heat to the circulating water of a heating system.
Um letzteres zu bewerkstelligen, ist der Motor ein«’ Umwälzpumpe des Heizungssystems von einem Temperaturfühler beaufschlagt, der den Innenraum des Speichers abfühlt. Daneben ist ein zweiter Temperaturfühler vorhanden, der die Beheizung des Speichers steuert.To accomplish the latter, the engine is powered 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 dem IS drei Temperaturfühler vorgesehen sind, die in Verbindung mit einem Feuerungsautomaten die Beheizung desFinally, a directly heated hot water tank has become known from DE-OS 3 310 023, in which three temperature sensors are provided which, in conjunction with an automatic burner control, heat the
Speichers steuern.Control memory.
Es ist Aufgabe der vorliegenden Erfindung, von Zeit zu Zeit auf 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 soge-20 nannte Legionärskrankheit verursachenden Bakterien zu unterbinden.It is an object of the present invention to heat from time to time to the floor area of the hot water storage tank, which often becomes cool due to the inflowing cold water when hot water is drawn or does not heat up sufficiently, to a higher temperature in order to increase the so-called To prevent 20 named bacteria causing Legionnaires' disease.
Die Lösung der Aufgabe erfolgt erfmdungsgemäß dadurch, daß der untere Thermostat mit einem Zeitglied gekoppelt ist, das die Erwärmung des Speicherwassers nur dann ermöglicht, wenn innerhalb einer vorgegebenen Zeitspanne keine durch den im mittleren oder oberen Bereich des Speicherraums angeordneten Thermostaten gesteuerte Erwärmung erfolgt ist. 25 Durch diese Ausgestaltung ist es möglich, innerhalb wählbarer Zeiträume abzufragen, ob der Speicher nachge heizt wurde. Ist dies nicht geschehen, so wird üb» das Zeitglied die Beheizung so fieigegeben, daß der gesamte Speicherinhalt auf eine die Abtötung der Bakterien gewährleistende Temperatur aufgeheizt wird.The object is achieved according to the invention in that the lower thermostat is coupled to a timer which only enables the storage water to be heated if, within a predetermined period of time, no heating has been carried out controlled by the thermostats arranged in the middle or upper region of the storage space. 25 With this configuration, it is possible to query within selectable periods whether the storage tank has been reheated. If this has not happened, the heating element is activated in such a way that the entire contents of the memory are heated to a temperature which ensures that the bacteria are killed.
Die einzige Zeichnungsfigur stellt in einem schematischen Vertikalschnitt einen Speicherbehälter (1) mit einem Doppelboden (2) dar. In den Speicherraum (3) dieses Speicherbehälters (1) mündet die Vorlaufleitung 30 (4) eines nicht dargestellten brennerbeheizten Wasserheizers, dessen Heißwasser den Speicherraum (3) zum Auf heizen des Speicherwassers in einer Wendel (5) durchströmt und sodann in der die Speicherdecke (6) durchsetzenden Rücklaufleitung (7) zum Wasserheizer zurückströmt. Eine Kaltwasserzufuhrleitung (8) durchsetzt ebenfalls die Speicherdecke (6) und mündet in den Bodenbereich des Speicherraumes (3). Eine Brauchwasserzapfleitung (9) geht von der Speicherdecke (6) aus. 35 Zur Überwachung der 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 (5) durchströmende Heißwasser ein und bei Erreichen eines oberen Grenzwertes schaltet er die Beheizung ab.The only drawing figure shows a schematic vertical section of a storage tank (1) with a raised floor (2). The supply line 30 (4) of a burner-heated water heater (not shown) opens into the storage room (3) of this storage tank (1), the hot water of which stores the storage room ( 3) flows through to heat the storage water in a spiral (5) and then flows back to the water heater in the return line (7) passing 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 hot water tap (9) starts from the storage ceiling (6). 35 To monitor the temperature of the tap water to be drawn off, a thermostat (10) is - as usual - arranged in the middle or upper area of the storage space (3). If the temperature falls below a temperature limit, he switches on the heating of the storage water by the hot water flowing through the coil (5) and switches off the heating when an upper limit value is reached.
Der untere zusätzliche Thermostat (11) im Bodenbereich sorgt hingegen dafür, daß die Wassertemperatur in 40 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 Zeitglied 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. 45 Durch dieses Zusammenwirken der beiden Thermostaten (10 und 11) werden demnach für die Entwicklung von Kleinstlebewesen erforderliche Mindestverweilzeiten, in denen die Temperatur den für die Keimtötung erforderlichen Mindestwert unterschreitet, zuverlässig vermieden. 50 55 -2- 60The lower additional thermostat (11) in the floor area, on the other hand, ensures that the water temperature in this floor area does not drop too long, permitting the development of microorganisms below a threshold value permitting development. For this purpose, this thermostat (11) can be coupled to a timer which 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. 45 This interaction of the two thermostats (10 and 11) therefore reliably avoids the minimum dwell times required for the development of microorganisms, in which the temperature falls below the minimum value required for germ killing. 50 55 -2- 60
