Bei der nachfolgenden Beschreibung zweier bevorzugter Ausführungsformen der vorliegenden Erfindung bezeichnen gleiche Bezugszeichen gleiche oder vergleichbare Komponenten.In the following description of two preferred embodiments of the present invention, like reference characters designate like or similar components.
Die in der vorstehenden Beschreibung, den Ansprüchen und den Zeichnungen offenbarten Merkmale können sowohl einzeln als auch in beliebiger Kombination für die Verwirklichung der Erfindung in ihren verschiedenen Ausgestaltungen von Bedeutung sein.The features disclosed in the foregoing description, the claims and the drawings may be of importance both individually and in any combination for the realization of the invention in its various forms.

Darüber hinaus umfasst der elektrische Wassererwärmer 100 zum Erhitzen von kaltem Wasser eine erste elektrische Heizrohrbaugruppe 40. Diese umfasst wiederum einen fest mit dem Innenbehälter 10 verbundenen Einbaukanal 41 und ein im Einbaukanal 41 aufgenommenes, erstes elektrisches Heizrohr 42 d.h. Heizmodul. Der Einbaukanal 41, welcher im Wesentlichen rohrförmig ausgebildet ist und aus dem gleichen Werkstoff wie der Innenbehälter 10 bestehen kann, ist an einem Ende offen und am anderen, gegenüberliegenden Ende geschlossen. Zudem befindet sich die gesamte Erstreckung des Einbaukanals 41 innerhalb des Innenbehälters 10 und sein offenes Ende ist durch Verschweißen an einer Querseite des Innenbehälters 10 befestigt, wodurch das erste elektrische Heizrohr 42 auf einfache Weise hineingeführt werden kann. Im ersten elektrischen Heizrohr 42 ist ein Widerstandsdraht mit hoher Impedanz (nicht dargestellt) angebracht, der über Leitungen (nicht bezeichnet) an eine 220V- oder 110V-Wechselstromversorgung anschließbar ist, um elektrische Energie in Wärme umzuwandeln. Das erste elektrische Heizrohr 42 kann durch Presspassung im Einbaukanal 41 befestigt sein. In der vorliegenden Ausführungsform kann der Einbaukanal als eine einteilige Erweiterung der Oberfläche des Innenbehälters angesehen werden, die das erste elektrische Heizrohr vom Wasser im Innenbehälter trennt. Andererseits kann das erste elektrische Heizrohr durch den Einbaukanal über dessen Wärmeleitung das Wasser im Innenbehälter erwärmen. Durch diese Trennung kann das elektrische Heizrohr vor Wassererosion geschützt werden. Bei Beschädigung des elektrischen Heizrohrs muss dieses zur Auswechselung und Reparatur nur herausgezogen werden, ohne den Innenbehälter entleeren zu müssen. Dadurch, dass der Einbaukanal einteilig mit dem Innenbehälter verschweißt ist, lassen sich gegenüber herkömmlichen lösbaren Verbindungen wie beispielsweise Flansch- oder Schraubverbindung eventuelle Leckagen und Energieverluste an den Verbindungsstellen zuverlässig vermeiden.In addition, the

Aus der Beschreibung der zweiten und dritten Ausführungsform wird ersichtlich, dass die Kombination von bisher bekannten, mittels Flansch- oder Schraubverbindungen angebrachten elektrischen Heizrohrbaugruppen mit der ersten elektrischen Heizrohrbaugruppe der vorliegenden Erfindung eine Erwärmung unterschiedlicher Wasserschichten ermöglicht, ohne dabei eine umfassende Änderung an bestehenden elektrischen Wassererwärmern vornehmen zu müssen. Zusätzlich hierzu wird der Wassererwärmer vorteilhafterweise durch die Wasser isolierende Ausgestaltung der ersten elektrischen Heizrohrbaugruppe vor Wassererosion geschützt. Alternativ können die elektrischen Heizrohrbaugruppen, welche gemeinsam für eine gleichzeitige Erwärmung von verschiedenen Wasserschichten sorgen, selbstverständlich identisch mit der ersten elektrischen Heizrohrbaugruppe aufgebaut sein, d.h. sie sind alle Wasser isolierend ausgebildet. Herstellerseitig kann dann bei verschiedenen, sich durch den Heizmodus voneinander unterscheidenen Wassererwärmertypen ein jeweils gleich aufgebauter Innenbehälter eingesetzt werden. So können z.B. innerhalb des Innenbehälters vertikal drei Einbaukanäle angebracht werden. Für einfache Wassererwärmertypen muss dann lediglich in einen der Einbaukanäle ein elektrisches Heizrohr eingesteckt werden und die übrigen Kanäle bleiben frei. Für Wassererwärmertypen mittlerer Klasse können zwei der Einbaukanäle und für Wassererwärmertypen der Luxusklasse alle drei Einbaukanäle mit elektrischen Heizrohren bestückt werden. Alternativ können aber auch mehr Einbaukanäle vorgesehen sein, oder ein konventionelles, mit Flanschen oder Schraubköpfen befestigtes elektrisches Heizrohr wird mit mehreren, vom Wasser getrennten elektrischen Heizrohren kombiniert. Aufgrund einer solchen durchgängigen Ausgestaltung und damit verbundener modularer Zusammensetzung lassen sich auf einer einzigen Fertigungsanlage verschiedene elektrische Wassererwärmertypen herstellen, was die Herstellungskosten erheblich reduziert.From the description of the second and third embodiments, it will be seen that the combination of previously known flanged or threaded electrical heater tube assemblies with the first electrical heating tube assembly of the present invention enables heating of different water layers without making a major change to existing electric water heaters to have to. In addition to this, the water heater is advantageously provided by the water insulating embodiment of first electric heating tube assembly protected against water erosion. Alternatively, the electrical heating tube assemblies, which together provide for a simultaneous heating of different water layers, of course, be constructed identically with the first electric heating tube assembly, ie they are all water insulating. Manufacturer side can then be used in different, different from each other by the heating mode water heater types each a same constructed inner container. For example, three mounting channels can be installed vertically inside the inner container. For simple types of water heater then only in one of the installation channels an electric heating tube must be inserted and the other channels remain free. For medium-class water heaters, two of the built-in channels and for luxury water heaters all three built-in ducts can be fitted with electric heating pipes. Alternatively, however, more installation channels can be provided, or a conventional, with flanges or screw heads attached electric heating tube is combined with several, separate from the water electric heating pipes. Due to such a continuous configuration and associated modular composition can be produced on a single production plant various types of electric water heaters, which significantly reduces the cost of production.
Bisher wurden Ausführungsformen der vorliegenden Erfindung dargestellt und beschrieben, die jedoch nicht jeweils nur eine separate Ausgestaltung enthalten. Im Rahmen der vorliegenden Erfindung können vielmehr die in den einzelnen Ausführungsformen offenbarten Ausgestaltungen auf geeignete Weise miteinander zu anderen, den Fachleuten auf diesem Gebiet naheliegenden Ausführungsformen kombiniert werden.Hitherto, embodiments of the present invention have been illustrated and described which, however, do not each include a separate embodiment. In the context of the present invention, on the contrary, the embodiments disclosed in the individual embodiments can be suitably combined with one another to form other embodiments which are obvious to the person skilled in the art.
Das oben Beschriebene stellt keine Einschränkung der Erfindung dar, sondern dient lediglich der beispielhaften Darstellung möglicher Ausführungsformen der Erfindung. Trotz der vorangehenden Beschreibung und Erläuterung am Beispiel eines horizontal angebrachten Wassererwärmers liegt es den Fachleuten auf diesem Gebiet nahe, dass die vorliegende Erfindung auch bei vertikal angebrachten Wassererwärmern Verwendung finden kann. Jede gleichwertige Ausführung oder Variation, welche von den Grundideen der Erfindung ausgeht, ist daher vom Schutzumfang der vorliegenden Erfindung umfasst.The above is not a limitation of the invention but is merely illustrative of possible embodiments of the invention. Despite the foregoing description and explanation, using the example of a horizontally mounted water heater, it will be apparent to those skilled in the art that the present invention can be used with vertically mounted water heaters. Any equivalent embodiment or variation, which is based on the basic ideas of the invention, is therefore included within the scope of the present invention.
