Beschreibung description

Die Erfindung bezieht sich auf einen elektrisch beheizten Durchlauferhitzer. The invention relates to an electrically heated instantaneous water heater.

Solche Geräte sind bekannt. Es sind auch schon Anzeigevorrichtungen an solchen Geräten bekanntgeworden, aus denen man die Soil-Wert-Ein-stellung für die gewünschte Warmwasser-Auslauftemperatur ersehen kann. Such devices are known. Display devices on devices of this type have already become known, from which the soil value setting for the desired hot water outlet temperature can be seen.

Nimmt ein Verbraucher einen solchen elektrisch beheizten Durchlauferhitzer in Betrieb, so befindet sich zunächst einmal in dem Rohrstrang zwischen Durchlauferhitzer und Zapfventil eine Kaltwassersäule. Diese Kaltwassersäule wird aus dem Zapfventil herausgelassen und verursacht Wasserkosten, ohne dass der Benutzer hierfür ein Äquivalent erhält, da er ja warmes Wasser wünscht. Weiterhin vergeht eine gewisse Zeit, bis der elektrische Durchlauferhitzer anspringt und bis seine Heizwendel oder sonstigen Heizkörper das durchmessende Wasser erwärmen. Auch hieraus resultiert zusätzlich zum eben genannten Wasserverbrauch ein weiterer Wasserverbrauch, für den der Benutzer kein Äquivalent erhält. Aus beiden genannten Zapfwasserverbräuchen ergibt sich ein Kostensaldo, da der Zapfwasserpreis von den Wasserversorgungsunternehmen tarifmässig festgelegt ist. Hinzu kommt zu dieser Kostenbelastung aber noch eine Abwasserkostenbelastung, da ja das nicht gewünschte kalte Zapfwasser über den Abwasserkanal fortgeleitet wird. If a consumer puts such an electrically heated instantaneous water heater into operation, there is firstly a cold water column in the tubing between the instantaneous water heater and the nozzle. This column of cold water is let out of the nozzle and causes water costs without the user being given an equivalent because he wants warm water. Furthermore, a certain amount of time passes before the instantaneous water heater starts up and until its heating coil or other heating element heats up the water. In addition to the water consumption just mentioned, this also results in a further water consumption for which the user receives no equivalent. A cost balance results from both of the above-mentioned tap water consumption, since the tap water price is set by the water supply companies according to the tariff. In addition to this cost burden, there is also a waste water cost burden, since the unwanted cold tap water is passed on via the sewer.

Aus der Fig. 1 ist ersichtlich, dass sich bei den einzelnen Zapfvorgängen, wie Händewaschen, Spülen, Duschen und Wannefüllen, eine Gesamtkostenbelastung ergibt, die vom eigentlichen Stromverbrauch und vom Wasserverbrauch bestimmt wird. Es zeigt sich aber, dass die heutigen tariflichen Belastungen des Wasserverbrauchs fast eine Grössenordnung erreichen, die dem Stromverbrauch entspricht. It can be seen from FIG. 1 that the individual dispensing processes, such as washing hands, rinsing, showering and filling the bathtub, result in a total cost burden which is determined by the actual power consumption and water consumption. It turns out, however, that today's tariff burdens on water consumption almost reach an order of magnitude that corresponds to electricity consumption.

Demgemäss muss es Ziel von Benutzern von Durchlauferhitzern und allgemein gesprochen, Warmwassererzeugern sein, den unnützen Wasserverbrauch bis zur Erzielung von warmem Wasser so gering wie möglich zu halten. Accordingly, it must be the aim of users of instantaneous water heaters and, generally speaking, hot water generators, to keep the useless water consumption as low as possible until hot water is obtained.

Demgemäss ist es Aufgabe der vorliegenden Erfindung, dafür zu sorgen, dass der Verbraucher dies erreichen kann. Accordingly, it is an object of the present invention to ensure that the consumer can achieve this.

Die Erfindung besteht in den Merkmalen des Patentanspruchs 1. The invention consists in the features of patent claim 1.

Durch diese Ausgestaltung ist es möglich, dass der Verbraucher jederzeit kontrollieren kann, wieviel ihn ein Zapfvorgang kostet, und dass er gehalten ist, den Zapfvorgang sobald als möglich abzubrechen, wenn er sein Ziel erreicht hat. With this configuration, it is possible for the consumer to be able to check at any time how much a dispensing operation will cost him, and for the consumer to stop the dispensing operation as soon as possible when he has reached his destination.

Die Merkmale der abhängigen Ansprüche dienen der weiteren Ausgestaltung des Gegenstandes des Patentanspruchs 1. The features of the dependent claims serve to further develop the subject matter of patent claim 1.

Die anliegenden Fig. 2 und 3 zeigen Ausführungsbeispiele der Erfindung in einer schematischen Darstellung. The attached FIGS. 2 and 3 show exemplary embodiments of the invention in a schematic representation.

Die Fig. 2 zeigt ein Gehäuse eines elektrisch beheizten, elektronisch gesteuerten Durchlauferhitzers, der neben anderen Elementen eine Anzeige 2 in Form einer LED-Treppe aufweist. Hierbei sind die einzelnen LED-Elemente in Form einer Leiter übereinander angeordnet, wobei der geringste Wert am unteren Ende 3, der höchste Verbrauchswert dem oberen Ende 4 zugeordnet ist. Je höher demgemäss die Anzeige aktiv ist, um so höher ist der Momentanwert der im Augenblick anfallenden Verbrauchskosten. Die Verbrauchskosten setzen sich aus den momentanen Kosten des Wasser- und Stromverbrauchs zusammen. Der Durchlauferhitzer weist noch vier Einstellelemente 5 bis 8 auf, wobei das Einstellelement 5 einen Soll-Wert-Geber für den Durchsatz oder für die Menge des gewünschten warmen Wassers bedeutet, der Geber 6 - der zusammen mit dem Geber 8 für den Verbraucher nicht sichtbar angeordnet ist - bewirkt eine Einstellung des Geldwertes pro verbrauchter Kilowattstunde, der Geber 8 eine Einstellung des Geldwertes pro verbrauchten m3 oder Liter Wasser und der Geber 7 die gewünschte Temperatur. Es ist eine Steueroder Regeleinrichtung im Gehäuse 1 vorgesehen, die die elektrische Leistung als Funktion der Einlauftemperatur, des Durchsatzes und der gewünschten Zapftemperatur beeinflusst. 2 shows a housing of an electrically heated, electronically controlled instantaneous water heater which, in addition to other elements, has a display 2 in the form of an LED staircase. The individual LED elements are arranged one above the other in the form of a ladder, the lowest value being assigned to the lower end 3 and the highest consumption value to the upper end 4. Accordingly, the higher the display is active, the higher the instantaneous value of the current consumption costs. The consumption costs are made up of the current costs of water and electricity consumption. The instantaneous water heater also has four setting elements 5 to 8, the setting element 5 being a setpoint value transmitter for the throughput or for the amount of the warm water desired, the transmitter 6 - which, together with the transmitter 8, is arranged so that it is invisible to the consumer is - causes a setting of the monetary value per kilowatt hour used, the encoder 8 a setting of the monetary value per m3 or liter of water used and the encoder 7 the desired temperature. A control or regulating device is provided in the housing 1, which influences the electrical power as a function of the inlet temperature, the throughput and the desired tap temperature.

Es leuchtet ein, dass man mit den beiden Justage-gebern 6 und 8 aufgrund des aktuell geltenden Strom- und Wasserpreises die Anzeige 2 justieren kann. Aufgrund der gewünschten Auslauftemperatur, die am Geber 7 vom Verbraucher vorgewählt werden kann, und des gleichfalls am Geber 5 vorgewählten Durchsatzes ergibt sich die momentane Kostenbelastung für den Verbraucher sofort und eindeutig ersichtlich. It makes sense that you can use the two adjustment sensors 6 and 8 to adjust display 2 based on the current electricity and water price. Based on the desired outlet temperature, which can be preselected by the consumer on the transmitter 7, and the throughput also preselected on the transmitter 5, the instantaneous cost burden for the consumer is immediately and clearly evident.

Beim Gerät nach Fig. 3 sind die Dinge etwas abgewandelt: Die Anzeige 2 besteht hier aus einer 7-Segment-Ziffernanzeige 9, die den kumulierten, sich aus Wasser- und Stromkosten zusammensetzenden Verbrauch dem Verbraucher darstellt. Die vier Soll-Wert-Geber sind die gleichen. In the device according to FIG. 3, things are somewhat modified: the display 2 here consists of a 7-segment numerical display 9, which represents the cumulative consumption of water and electricity costs to the consumer. The four setpoint transmitters are the same.

Aufgrund der Erfindung wird bewirkt, dass der Verbraucher sowohl zum Strom- wie auch zum Wassersparen angehalten wird. The effect of the invention is that the consumer is stopped to save both electricity and water.
