Description
AT 408 708 BAT 408 708 B
Die Erfindung bezieht sich auf einen Trinkwasserspeicher gemäß dem Oberbegriff des Anspruches 1.The invention relates to a drinking water tank according to the preamble of claim 1.
Emaillierte oder mit einer ähnlichen Beschichtung versehene Trinkwasserspeicher müssen wasserseitig korrosionsgeschützt werden, da die Beschichtung Fehlstellen aufweisen kann, an denen die Behälter zu korrodieren beginnen. Für diesen Schutz sind Anoden vorgesehen, die bei einem Trinkwasserspeicher der eingangs erwähnten Art aus einem inerten Material hergestellt sind und mit einer Spannungsversorgung verbunden sind.Enamelled or similarly coated drinking water storage tanks must be protected against corrosion on the water side, since the coating may have imperfections at which the tanks begin to corrode. For this protection, anodes are provided which are made of an inert material in a drinking water storage tank of the type mentioned at the outset and are connected to a voltage supply.
Bei bekannten derartigen Trinkwasserspeichern sind die Anoden mit einem Netzanschluß bzw. einer Steckdose verbunden. Dabei ergibt sich jedoch der Nachteil, daß ein Stromanschluß an das öffentliche Netz auch bei ansonsten netzunabhängigen direkt beheizten Speichern vorhanden sein muß. Dabei muß sichergestellt sein, daß der Stromanschluß nicht vom Netz getrennt werden kann, sodaß ein entsprechender Schutz gegen Kabelbruch und eine Trennung der Zuleitung vom Netz u.dgl. vorgesehen werden muß, was mit einem erheblichen Aufwand verbunden ist.In known drinking water tanks of this type, the anodes are connected to a mains connection or a socket. However, this has the disadvantage that a power connection to the public network must also be present in the case of directly heated stores which are otherwise independent of the network. It must be ensured that the power connection cannot be disconnected from the network, so that appropriate protection against cable breakage and disconnection of the supply line from the network and the like. must be provided, which is associated with considerable effort.
Aus der JP 92 75 92 A1 ist ein thermionisches Element bekanntgeworden, mit dem Wärmeenergie in Elektroenergie umgewandelt werden kann, wie es zur Anwendung in Boilern zum Ausnutzen von sonst nicht nutzbarer Abhitze verwendet werden kann.From JP 92 75 92 A1 a thermionic element has become known with which thermal energy can be converted into electrical energy, as can be used in boilers for utilizing otherwise useless waste heat.
Ziel der Erfindung ist es, den eingangs geschilderten Nachteil zu vermeiden und einen Trinkwasserspeicher der eingangs erwähnten Art vorzuschlagen, der netzunabhängig betrieben werden kann.The aim of the invention is to avoid the disadvantage described at the outset and to propose a drinking water reservoir of the type mentioned at the outset which can be operated independently of the network.
Erfindungsgemäß wird dies bei einem Trinkwasserspeicher der eingangs erwähnten Art durch die kennzeichnenden Merkmalen des Anspruches 1 erreicht.According to the invention this is achieved in a drinking water storage tank of the type mentioned at the outset by the characterizing features of claim 1.
Durch die vorgeschlagenen Maßnahmen ist es möglich, die Temperaturdifferenz zwischen dem Speicherbehälter und der Umgebung, welche meist ca. 40K beträgt, für die Spannungsversorgung der nicht verzehrenden Anode zu nutzen.The proposed measures make it possible to use the temperature difference between the storage container and the environment, which is usually approximately 40K, for the voltage supply of the non-consuming anode.
Durch die Merkmale des Anspruches 2 ist es möglich, die Spannung des Thermoelements auf ein höheres Niveau zu heben.The features of claim 2 make it possible to raise the voltage of the thermocouple to a higher level.
Dabei ist es vorteilhaft, die Merkmale des Anspruches 3 vorzusehen.It is advantageous to provide the features of claim 3.
Durch diese Maßnahmen ergibt sich der Vorteil, daß praktisch die größte verfügbare Temperaturdifferenz für die Spannungsversorgung genutzt wird.These measures have the advantage that practically the largest available temperature difference is used for the voltage supply.
Die Erfindung wird nun anhand der Zeichnung näher erläutert, die schematisch einen erfindungsgemäßen Trinkwasserspeicher zeigt.The invention will now be explained in more detail with reference to the drawing, which schematically shows a drinking water tank according to the invention.
Dabei weist ein Trinkwasserspeicher 1 einen Speicherbehälter 6 auf, in dessen untersten Bereich eine Brennkammer 7 angeordnet ist, in der sich ein Brenner 8 befindet, der über eine Gasleitung 9 und ein Gasventil 10 mit Gas versorgbar ist. Dabei ist die Brennkammer 7 mit einem Abgasrohr 11 versehen, das sich vertikal durch den Speicher 1 hindurch erstreckt.A drinking water tank 1 has a storage tank 6, in the lowest region of which a combustion chamber 7 is arranged, in which there is a burner 8 which can be supplied with gas via a gas line 9 and a gas valve 10. The combustion chamber 7 is provided with an exhaust pipe 11 which extends vertically through the store 1.
Weiters ist der Speicher 1 mit einem in dessen untersten Bereich mündenden Kaltwasserzulauf 12 und einer aus dem obersten und daher wärmsten Bereich des Speichers 1 wegführenden Brauchwasserleitung 13 versehen.Furthermore, the storage tank 1 is provided with a cold water inlet 12 opening into its lowermost area and a service water pipe 13 leading away from the uppermost and therefore warmest area of the storage tank 1.
An der Außenseite des Speicherbehälters 6 ist an dessen Außenseite ein Thermoelement 5 angeordnet, das sich in gut wärmeleitender Verbindung mit dem Speicherbehälter 6 befindet.On the outside of the storage container 6, a thermocouple 5 is arranged on the outside thereof, which is in a heat-conducting connection with the storage container 6.
Weiters steht das Thermoelement 5 mit der Umgebung oder dem Kaltwasserzulauf 12 in wärmeleitender Verbindung und nützt so den Temperaturunterschied zwischen den beiden Punkten.Furthermore, the thermocouple 5 is in a thermally conductive connection with the surroundings or the cold water inlet 12 and thus uses the temperature difference between the two points.
Die durch das Thermoelement 5 erzeugte elektrische Spannung wird über eine Verbindungsleitung 4 einem Umsetzer 3 zugeführt und auf ein höheres Niveau angehoben und an eine in das Innere des Speicherbehälters 6 hineinragende Anode 2 aus einem inerten Material gelegt, die für den Korrosionsschutz sorgt.The electrical voltage generated by the thermocouple 5 is fed via a connecting line 4 to a converter 3 and raised to a higher level and placed on an anode 2 protruding into the interior of the storage container 6 made of an inert material, which provides corrosion protection.
Durch die an die Anode 2 angelegte Spannung wird der Speicherbehälter 6 gegen Korrosion geschützt.The voltage applied to the anode 2 protects the storage container 6 against corrosion.
Durch das Thermoelement 5 ist es möglich, auf einen Netzanschluß für den Trinkwasserspeicher 1 zu verzichten.The thermocouple 5 makes it possible to dispense with a mains connection for the drinking water tank 1.
Durch einen Akku ist eine Speicherung der vom Thermoelement gelieferten elektrischen Energie möglich. 2The battery can store the electrical energy supplied by the thermocouple. 2
