Description

Die Erfindung bezieht sich auf einen Elektro-Durchlauferhitzer.The invention relates to an electric instantaneous water heater.

Elektrodurchlauferhitzer verfügen über ein Gehäuse, in dem sich zumindest der Heizblock sowie die Regelung oder Steuerung befindet. Der Elektrodurchlauferhitzer ist mit einem Kaltwasserzulauf, einer Warmwasserleitung und einem Stromanschluss verbunden. Zwar sind in der Regel Elektrodurchlauferhitzer relativ kompakt, doch können sie aufgrund der vorgegebenen Bauform an manchen Stellen nicht montiert werden. Das Gehäuse ist jedoch notwendig, damit kein Spritzwasser zu einem Kurzschluss oder einer sonstigen Gefährdung von Nutzern führen kann.Electric water heaters have a housing in which at least the heating block and the control or regulation is located. The electric instantaneous water heater is connected to a cold water inlet, a hot water pipe and a power connection. Although usually electric water heaters are relatively compact, but they can not be mounted due to the given design in some places. The housing is necessary, however, so that no splash water can lead to a short circuit or other endangering of users.

Aus EP 309710 A1 ist ein Elektrodurchlauferhitzer bekannt, in welchem der Heizblock sowie der starr verbundene Zu- und Ablauf von einem flexiblen Schlauch umgeben sind, wodurch seine Kontur starr vorliegt und nicht weiter verändert werden kann.Out EP 309710 A1 an electric instantaneous water heater is known in which the heating block and the rigidly connected inlet and outlet are surrounded by a flexible hose, whereby its contour is rigid and can not be further changed.

Der Erfindung liegt die Aufgabe zugrunde, einen Elektrodurchlauferhitzer derart zu gestalten, dass er flexibel montierbar ist.The invention has for its object to make an electric water heater so that it can be flexibly mounted.

Dies wird gemäß den Merkmalen des unabhängigen Anspruchs 1 dadurch gelöst, dass der Elektrodurchlauferhitzer nicht in einem starren Gehäuse montiert ist, sondern die wasserführenden Bauteile über flexible Leitungen verbunden und in einem wasserdichten, flexiblen Schlauch angeordnet sind. Hierdurch ist es möglich, dass der Durchlauferhitzer bedarfsgerecht an unterschiedlichen Montageräumen montiert werden kann. Hierdurch können die Komponenten auch in verwinkelten und kleinen Hohlräumen, zum Beispiel unter der Duschwanne, in Zwischendecken und anderen verwinkelten Bauräumen, installiert werden. Durch die flexible Anordnung können die Bauteile platzsparend in vielfältiger Form verlegt werden. Durch diese Erfindung wird ein Durchlauferhitzer flexibel in seinen Abmaßen.This is achieved according to the features of independent claim 1, characterized in that the electric water heater is not mounted in a rigid housing, but the water-bearing components are connected via flexible lines and arranged in a waterproof, flexible hose. This makes it possible that the water heater can be mounted as needed to different mounting spaces. As a result, the components can also be installed in winding and small cavities, for example under the shower tray, in false ceilings and other winding installation spaces. Due to the flexible arrangement, the components can be installed to save space in a variety of forms. By this invention, a water heater is flexible in its dimensions.

Vorteilhafte Ausgestaltungen der Erfindung ergeben sich durch die Merkmale der abhängigen Ansprüche.Advantageous embodiments of the invention will become apparent from the features of the dependent claims.

So ist es vorteilhaft, wenn zu den wasserführenden Bauteilen in dem wasserdichten, flexiblen Schlauch auch eine Vorrichtung zur Detektierung von Wasserfluss, zum Beispiel ein Wasserschalter, Differenzdruckschalter und / oder Flügelrad gehört.So it is advantageous if the water-bearing components in the waterproof, flexible hose also includes a device for detecting water flow, for example a water switch, differential pressure switch and / or impeller.

Ist der wasserdichte, flexible Schlauch zumindest mit dem Kaltwasserzulauf sowie der Warmwasserleitung wasserdicht verbunden, so kann keine Feuchtigkeit zu den umschlossenen Komponenten gelangen.If the watertight, flexible hose is connected in a watertight manner at least to the cold water inlet and the hot water pipe, moisture can not reach the enclosed components.

Optional kann der wasserdichte, flexible Schlauch alle wasserführenden Bauteile wasserdicht umschließen. Ist beispielsweise der wasserdichte, flexible Schlauch ein Schrumpfschlauch, so können die Komponenten in der gewünschten Position montiert werden. Anschließend wird der Schrumpfschlauch erwärmt, wodurch der Schrumpfschlauch sich an die Komponenten in der montierten Position anschmiegt.Optionally, the waterproof, flexible hose can waterproof enclose all water-bearing components. For example, if the waterproof, flexible hose is a shrink tube, the components can be mounted in the desired position. Subsequently, the shrink tube is heated, whereby the shrink tube conforms to the components in the mounted position.

Der wasserdichte, flexible Schlauch kann auch die Elektrik oder Elektronik umschließen. Die elektrische Zuleitung des Heizblocks und / oder der Elektrik oder Elektronik kann parallel mit dem Kaltwasserzulauf oder der Warmwasserleitung aus dem wasserdichten, flexiblen Schlauch geführt werden. Im wasserdichten, flexiblen Schlauch kann ferner ein Empfänger einer Funkfernbedienung untergebracht sein.The waterproof, flexible hose can also enclose the electrical or electronics. The electrical supply of the heating block and / or the electrical system or electronics can be performed in parallel with the cold water inlet or the hot water pipe from the waterproof, flexible hose. In the waterproof, flexible hose can also be housed a receiver of a radio remote control.

Die Erfindung wird nun anhand der Figur detailliert erläutert.The invention will now be explained in detail with reference to FIG.

Die Figur zeigt einen Elektro-Durchlauferhitzer mit einem Kaltwasserzulauf 1, einem Flügelrad 5, einem Stellventil 13, einem Heizblock 2 sowie einer Warmwasserleitung 3 seriell als wasserführende Bauteile, die über flexible Leitungen 11 miteinander verbunden sind. Diese sind in einem wasserdichten, flexiblen Schlauch 4 angeordnet. Der wasserdichte, flexible Schlauch 4 umschließt auch eine Elektronik 6 sowie einen Kondensator 14 zur Vermeidung von Störungen anderer Elektrogeräte und einen Sicherheitsschalter 15. Eine elektrische Zuleitung 7 führt zur Elektronik 6; von dieser führt eine elektrische Leitung 8 zum Heizblock 2. Die elektrische Zuleitung 7 wird parallel mit dem Kaltwasserzulauf 1 aus dem wasserdichten, flexiblen Schlauch 4 geführt. Im wasserdichten, flexiblen Schlauch 4 ist ferner ein Empfänger 12 einer Funkfernbedienung untergebracht. Dieser Empfänger 12 ist mit der Elektronik 6 verbunden. Mit der elektrischen Zuleitung 7 wird eine Verbindung zu einer Bedieneinrichtung 9 aus dem wasserdichten, flexiblen Schlauch 4 geführt. In der Warmwasserleitung 3 ist ein Temperatursensor 10, der mit der Elektronik 6 über Kabel oder Funk verbunden ist, angeordnet.The figure shows an electric water heater with a cold water inlet 1, an impeller 5, a control valve 13, a heating block 2 and a hot water pipe 3 serially as water-bearing components, which are connected to each other via flexible lines 11. These are arranged in a waterproof, flexible hose 4. The waterproof, flexible hose 4 also encloses electronics 6 and a capacitor 14 to prevent interference with other electrical appliances and a safety switch 15. An electrical lead 7 leads to the electronics 6; From this leads an electrical line 8 to the heating block 2. The electrical supply line 7 is performed in parallel with the cold water inlet 1 from the waterproof, flexible hose 4. In the waterproof, flexible hose 4, a receiver 12 of a radio remote control is also housed. This receiver 12 is connected to the electronics 6. With the electrical supply line 7, a connection to an operating device 9 is guided out of the watertight, flexible hose 4. In the hot water pipe 3, a temperature sensor 10, which is connected to the electronics 6 via cable or radio arranged.

Zur Montage wird der wasserdichte, flexible Schlauch 4 mit den darin angeordneten Komponenten an gewünschtem Einbauort montiert. Handelt es sich bei dem wasserdichten, flexiblen Schlauch 4 um einen Schrumpfschlauch, so wird der Schlauch erhitzt, so dass er sich an die Komponenten anschmiegt.For mounting the waterproof, flexible hose 4 is mounted with the components arranged therein at the desired installation location. If the waterproof, flexible hose 4 is a shrink hose, the hose is heated so that it conforms to the components.

Beim Betrieb des Durchlauferhitzers fließt Wasser durch den Kaltwasserzulauf 1 ein. Beim Durchströmen des Flügelrades 5 wird ein Signal erzeugt, das an die Elektronik 6 weitergeleitet wird. Die Elektronik 6 steuert daraufhin den Heizblock 2 an. Das Wasser wird in dem Heizblock 2 erwärmt und strömt in die Warmwasserleitung 3. Der Temperatursensor 10 übermittelt die Temperatur des ausfließenden Wassers an die Elektronik 6, welche die Heizleistung des Heizblocks 2 nachregelt, damit die Auslauftemperatur der vorgegebenen Temperatur entspricht. Kann die Solltemperatur nicht erreicht werden, da die zur Verfügung stehende Heizleistung zu gering ist, so wird das Stellventil 13 so weit geschlossen, bis die Solltemperatur erreicht wird. Die Solltemperatur kann an der kabelgebundenen Bedieneinrichtung 9 oder einem dem Empfänger 12 einer Funkfernbedienung zugeordneten Sender eingestellt werden.During operation of the water heater, water flows through the cold water inlet 1. As it flows through the impeller 5, a signal is generated, which is forwarded to the electronics 6. The electronics 6 then controls the heating block 2. The water is heated in the heating block 2 and flows into the hot water pipe 3. The temperature sensor 10 transmits the temperature of the outflowing water to the electronics 6, which adjusts the heating power of the heating block 2, so that the outlet temperature corresponds to the predetermined temperature. If the setpoint temperature can not be reached, since the available heating power is too low, the control valve 13 is closed so far until the setpoint temperature is reached. The setpoint temperature can be set at the wired operating device 9 or a transmitter associated with the receiver 12 of a radio remote control.

Abweichend hiervon kann der Heizblock 2 auch mit einer vorgegebenen, konstanten Heizleistung betrieben werden. Der Heizblock 2 kann einen Blankdraht oder Rohrheizkörper beinhalten.Notwithstanding this, the heating block 2 can also be operated with a predetermined, constant heating power. The heating block 2 may include a bare wire or tubular heater.

Der wasserdichten, flexiblen Schlauch 4 kann optional vom Kaltwasserzulauf 1 bis zum Heizblock 2 sowie vom Heizblock 2 bis zur Warmwasserleitung 3 die wasserführenden Bauteile umschließen, so dass der Heizblock 2 selbst nicht umschlossen ist.The watertight, flexible hose 4 can optionally surround the water-carrying components from the cold water inlet 1 to the heating block 2 and from the heating block 2 to the hot water pipe 3, so that the heating block 2 itself is not enclosed.

Die Wasser- und Elektroleitungen sowie Kontakte können verschraubt, gesteckt und / oder über Bajonetteverbindungen verbunden sein.The water and electrical lines and contacts can be screwed, plugged and / or connected via bayonet connections.
