Abstract

The electric instantaneous heater (1) has a box-shaped housing with a cold-water inlet (2), a control arrangement (3), a heating section (5) and a hot-water outlet (7). Cold-water inlet (2) and hot-water outlet (7) are connected movably to the heating section (5) via flexible, preferably electrically insulating lines (4, 6). In the case of a fixed position of the heating section, inlet and outlet can therefore be adapted positionally to a predetermined water-connection pattern, if appropriate even crossed over. The hood of the housing can therefore be arranged in any arrangement in relation to the hot-water tapping point in order to satisfy aesthetic and ergonomic requirements. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Anordnung und ein Verfahren zur Montage eines elektrischen Durchlauferhitzers, der ein im wesentlichen kastenförmiges Gehäuse mit wenigstens einem randnah an einer Frontplatte angebrachten Bedienknopf und eine mit einem Kaltwasser-Einlauf und einem Warmwasser-Auslauf verbundene Heizstrecke aufweist. Ein derartiger Durchlauferhitzer ist aus dem Dokument DE-A- 3 816 817 bekannt.The invention relates to an arrangement and a Method of assembling an electric instantaneous water heater, which is a substantially box-shaped housing with at least a control button attached to the edge of a front panel and one with a cold water inlet and one Has hot water outlet connected heating section. Such a water heater is known from document DE-A-3 816 817.

Herkömmliche aus der Praxis bekannten Durchlauferhitzer haben entweder auf der Unterseite oder auf der Rückseite lagefest installierte Ein- und Ausläufe. Das Installationsmuster am Durchlauferhitzer entspricht dem Wandanschlußmuster der Warm- und Kaltwasseranschlüsse. Konventionell liegt der Warmwasseranschluß rechts und der Kaltwasseranschluß in vorgegebenem Abstand vom Warmwasseranschluß links. Durchlauferhitzer werden üblicherweise möglichst nahe der zugehörigen Zapfstelle(n) an einer Wand montiert. Bei Obertischmontage muß der Bedienknopf für den Benutzer in erreichbarer Höhe liegen. Er ist daher regelmäßig nahe dem unteren Gehäuserand angeordnet, wo er selbst für kleinwüchsige Personen erreichbar ist. Aus optischen oder ästetischen Gründen wird zunehmend die Untertischmontage elektrischer Durchlauferhitzer bevorzugt. Das Anschlußmuster herkömmlicher Durchlauferhitzer gestattet jedoch in der Regel nur eine "aufrechte" Positionierung des Durchlauferhitzers, wobei sich der Bedienknopf am unteren Geräterand befindet. Dies hat den Nachteil, daß sich der Benutzer bei Betätigung des Bedienknopfes entweder tief unter das Waschbecken bücken oder sogar knien muß, um den Bedienknopf zu erreichen. Auch Quermontagen sind mit herkömmlichen Geräten und Montageanordnungen allenfalls unter Zwischenschaltung von Adaptern möglich, die das Bauvolumen vergrößern.Conventional instantaneous water heaters known from practice have either on the bottom or on the back fixed installed inlets and outlets. The installation pattern on the instantaneous water heater corresponds to the wall connection pattern the hot and cold water connections. Conventional the hot water connection is on the right and the cold water connection at a specified distance from the hot water connection Left. Instantaneous water heaters are usually as close as possible the associated tap (s) mounted on a wall. At The control button must be accessible to the user in the upper table Height. It is therefore regularly close to the lower one Housing edge arranged where it even for small stature People can be reached. From optical or aesthetic Under-desk mounting is becoming increasingly electrical Instantaneous water heater preferred. The connection pattern more conventional However, instantaneous water heaters are usually only permitted an "upright" positioning of the water heater, whereby the control button is at the bottom of the device. This has the disadvantage that the user when operating of the control button either bend deep under the sink or even kneel to reach the control button. Also Cross mounting is with conventional equipment and mounting arrangements at most with the interposition of adapters possible, which increase the construction volume.

Der Erfindung liegt daher die Aufgabe zugrunde, die Montagemöglichkeiten des Durchlauferhitzers zu erweitern, um gleichermaßen optische bzw. ästhetische wie auch ergonomische Bedürfnisse zu befriedigen.The invention is therefore based on the task, the mounting options of the instantaneous water heater to expand equally optical, aesthetic and ergonomic Satisfy needs.

Bei der Anordnung der eingangs genannten Art wird diese Aufgabe erfindungsgemäß dadurch gelöst,

  • daß in den Wasserweg einerseits zwischen Kaltwasser-Einlauf und Heizstrecke und andererseits zwischen Heizstrecke und Warmwasser-Auslauf eine flexible Leitung eingebunden ist;
  • daß Kaltwasser-Einlauf und Warmwasser-Auslauf lageveränderlich an ein außen vorgegebenes Wasseranschlußmuster anschließbar sind, wobei das Bewegungsspiel zwischen der lagefesten Heizstrecke und Einlauf und Auslauf bei deren Verbindung mit dem Wasseranschlußmuster durch die flexiblen Leitungen zur Verfügung gestellt wird; und
  • daß Kaltwasser-Einlauf und Warmwasser-Auslauf so gelegt und mit den Kaltwasser- und Warmwasser-Anschlüssen des Wasseranschlußmusters verbunden sind, daß der Bedienknopf auf einem der Warmwasser-Zapfstelle möglichst angepaßten Niveau liegt und daher ergonomisch betätigbar ist.
  • In the arrangement of the type mentioned in the introduction, this object is achieved according to the invention in that
  • that a flexible line is integrated into the water path on the one hand between the cold water inlet and the heating section and on the other hand between the heating section and the hot water outlet;
  • that cold water inlet and hot water outlet can be connected to an externally specified water connection pattern, the play of movement between the fixed heating section and inlet and outlet being provided by the flexible lines when they are connected to the water connection pattern; and
  • that cold water inlet and hot water outlet are placed and connected to the cold water and hot water connections of the water connection pattern that the control button is on a level adapted to the hot water tap and is therefore ergonomically operable.
  • Verfahrensmäßig wird diese Aufgabe erfindungsgemäß dadurch gelöst, daß je eine flexible Leitung zwischen Kaltwasser-Einlauf und Heizstrecke sowie zwischen Heizstrecke und Warmwasser-Auslauf in den Wasserweg eingebunden wird, daß das Gehäuse des Durchlauferhitzers sodann in eine geeignete Lage zum Wasseranschlußmuster gebracht und Warmwasser-Auslauf und Kaltwasser-Einlauf mit den zugehörigen Wasserwasser- und Kaltwasser-Anschlüssen des Wasseranschlußmusters verbunden, wenn nötig, gekreuzt werden, wobei das Bewegungsspiel der flexiblen Leitungen zum Ausgleich von Lagedifferenzen ausgenutzt wird. Die Verwendung von Kunststoffschläuchen im Anschluß an eine Heizstrecke eines Durchlauferhitzers ist aus der DE 36 09 213 A1 bekannt. Allerdings sollen die Schläuche dabei lediglich Wasserwiderstandskanäle bilden. Eine etwaige Flexibilität der Schläuche wird nicht angesprochen. Vor allen Dingen findet sich kein Hinweis dahingehend, mit Hilfe der Schläuche die Montagemöglichkeiten des Durchlauferhitzers zu erweitern.In terms of method, this object is achieved according to the invention solved that a flexible pipe between the cold water inlet and heating section and between heating section and Hot water spout is integrated into the waterway that the housing of the instantaneous water heater then into a suitable one Position brought to the water connection pattern and hot water outlet and cold water inlet with the associated water water and cold water connections of the water connection pattern connected, if necessary, crossed, the movement play the flexible cables to compensate for differences in position is exploited. The use of plastic hoses following a heating section of a water heater is known from DE 36 09 213 A1. However, should the hoses only form water resistance channels. Any flexibility of the hoses is not addressed. Above all, there is no indication that with the help of the hoses the mounting options of the Extend water heater.

    Letzeres hingegen wird mit der Erfindung erreicht. Aufgrund der Beweglichkeit von Kaltwasser-Einlauf und Warmwasser-Auslauf gegenüber der gerätefesten Heizstrecke werden besondere Montageplatten oder Adapter zum Kreuzen oder zur Lageänderung der Rohranschlüsse überflüssig. Die Lage des Durchlauferhitzergehäuses und damit des Bedienknopfs wird dadurch unabhängig von dem jeweils vorgegebenen Wandanschlußmuster. Der elektrische Durchlauferhitzer kann vom Installateur an derjenigen Stelle und in derjenigen Anschlußposition angebracht werden, die der Kunde aus optischen, ästhetischen und/oder ergonomischen Gründen wünscht.The latter, however, is achieved with the invention. Because of the flexibility of the cold water inlet and hot water outlet compared to the fixed heating section special mounting plates or adapters for crossing or There is no need to change the position of the pipe connections. The location of the Instantaneous water heater housing and thus the control button thereby independent of the given wall connection pattern. The electric instantaneous water heater can be used by the installer at that point and in that connection position be attached, which the customer from optical, aesthetic and / or ergonomic reasons.

    Bei Obertischmontage wird der Bedienknopf möglichst nahe des unteren Randes (wie bei herkömmlichen Heizgeräten) und bei Untertischmontage nahe des oberen Randes (entgegen herkömmlicher Montage) angeordnet. Bei einem häufig vorteilhaften Ausführungsbeispiel ist der Bedienknopf nahe einer Ecke einer viereckigen Frontplatte angeordnet. Diese Ecke wird dann wiederum aus ergonomischen Gründen der Warmwasserzapfstelle benachbart angeordnet.The control button is as close as possible to the top table the lower edge (as with conventional heaters) and when mounted under the table near the top edge (contrary to conventional Assembly) arranged. With a frequently advantageous The embodiment is the control button near a corner a square front panel. This corner will then again for ergonomic reasons the hot water tap arranged adjacent.

    Alternativ oder zusätzlich zu der zuvor beschriebenen Aufgabenlösung sieht die Erfindung vor, daß das kastenförmige Gehäuse aus einem die Heizstrecke tragenden Unterteil und einer den Bedienknopf und die Frontplatte tragenden Haube besteht, die mit dem Unterteil über zwei örtlich getrennte Verbindungsvorrichtungen form- und/oder kraftschlüssig verbindbar ist; daß das Unterteil fest montiert ist; und daß die beiden Verbindungsvorrichtungen sowohl an der Haube, als auch am Unterteil achssymmetrisch derart angeordnet sind, daß die Haube in zwei um 180° um die Achse gedrehten Positionen am Unterteil montierbar ist. Mit dieser alternativen Möglichkeit zum Verschwenken der Haube bei ansonsten stets gleichbleibender Anordnung des Unterteils und der funktionswesentlichen Komponenten des elektrischen Durchlauferhitzers können die Vorteile der Erfindung ohne wesentliche Änderung des Aufbaus des Durchlauferhitzers genutzt werden. Es bedarf nur einer geeigneten Konfiguration und Anordnung der Verbindungselemente, welche die beiden getrennten Verbindungsvorrichtungen einerseits am Unterteil und andererseits an der Haube bilden. Diese müssen so ausgebildet sein, daß sie geeignet ineinander greifen und ihre Verbindungsfunktion unabhängig von der jeweiligen Position der Haube erfüllen.Alternatively or in addition to that previously described The invention provides that the box-shaped solution to the problem Housing made of a lower part supporting the heating section and one carrying the control button and the front panel Hood exists, which with the lower part over two locally separated Connection devices positive and / or non-positive is connectable; that the lower part is fixed; and that the two connecting devices both on the hood, as well as arranged axially symmetrically on the lower part are that the hood is rotated in two by 180 ° around the axis Positions can be mounted on the lower part. With this alternative Possibility of pivoting the hood otherwise always the same arrangement of the lower part and the essential components of the electric instantaneous water heater can take advantage of the invention without essential Change in the design of the instantaneous water heater used will. All that is required is a suitable configuration and arrangement of the connecting elements which separate the two Connecting devices on the one hand on the lower part and on the other hand form on the hood. These must be trained in this way be that they mesh appropriately and their connection function regardless of the position of the Meet hood.

    Unter Verwendung der Merkmale des Patentanspruchs 8 wird auch der Tropfwasserschutz gewährleistet, der bisher nur bei Durchlauferhitzern mit einer einzigen vorgegebenen Relativposition von Haube und Unterteil möglich war.Using the features of claim 8 also the drip water protection, which was previously only guaranteed Instantaneous water heaters with a single predetermined relative position of hood and lower part was possible.

    Vorzugsweise ist ein federbelastetes Rückschlagventil auf der Kaltwasserseite der Heizstrecke derart angeordnet, daß es einen Rückstrom von Wasser in den Kaltwasseranschluß verhindert. Die Federbelastung macht die Funktion des Rückschlagventils unabhängig von der jeweiligen Montagelage des Geräts. Gewichtsbelastete Rückschlagventile, die bei herkömmlichen Elektroheizgeräten in der Regel verwendet werden, sind nur in einer "aufrechten" Position des Heizgeräts funktionsfähig.A spring-loaded check valve is preferably open the cold water side of the heating section arranged such that it prevents a backflow of water into the cold water connection. The spring load makes the check valve function regardless of the respective mounting position of the device. Weighted Check valves used in conventional electric heaters usually used are only in one The heater is in the "upright" position.

    Die universelle Einbaumöglichkeit gestattet es, dem Elektroheizgerät eine Gehäuseform ähnlich üblichen Badezimmer-Möbelelementen zu geben und das Gerät als Modul in eine Systemwand zu integrieren. Beispielsweise kann das Heizgerät als Spiegelelement verwendet werden, wenn seine Frontplatte verspiegelt ist.The universal installation option allows the electric heater a housing shape similar to common bathroom furniture elements to give and the device as a module in a system wall to integrate. For example, the heater can be used as Mirror element can be used if its front panel is mirrored is.

    Eine besonders günstige, weil flachbauende Ausführungsform ergibt sich, wenn der elektrische Durchlauferhitzer eine aus rohrförmigen Heizmodulen bestehende Heizstrecke hat. Diese Ausführung ist in der älteren Patentanmeldung P 42 08 675.2 vom 18. März 1992 beschrieben, deren Inhalt in die vorliegende Beschreibung einbezogen wird.A particularly inexpensive, because flat construction embodiment arises when the electric instantaneous water heater turns off has tubular heating modules existing heating section. This execution is in the older patent application P 42 08 675.2 from March 18, 1992, the contents of which are described in the present description is included.

Stromab des Anschlußblocks 2' sind die Steuereinrichtung 3 und verschiedene, bei Durchlauferhitzern übliche Meß- und Steuerelemente angeordnet. In der Steuereinrichtung 3 sind TRIAC's 31 zur separaten Steuerung der Heizleistung der einzelnen Heizmodule 5a, 5b und 5c über deren Heizwendel 50a, 50b und 50 vorgesehen. Die Heizwendel 50a-c bestehen aus blanken Heizwiderstandsdrähten, die einen vorzüglichen Wärmeübergang zu dem zu beheizenden Fluid (Wasser) gewährleisten. Vorgeschrieben sind bestimmte Isolationswiderstände zwischen blanken Heizwendeln und der nächsten metallischen Anschlußstelle im Strömungsweg des Wassers. Dementsprechend lang müssen die Fluidleitungen zwischen den jeweiligen Heizmodulen 5a bzw. 5c und den Anschlüssen auf der Kalt- bzw. Warmwasserseite sein. Diese Fluidleitungswege werden bei dem dargestellten Durchlauferhitzer durch flexible Schläuche 4', 6 aus elektrisch isolierendem Material gebildet. Diese Schläuche lassen sich einerseits einfach mit entsprechenden Anschlußstutzen kuppeln und andererseits einfach und platzsparend verlegen. So können sie beispielsweise in Schleifen hinter der Heizstrecke 5 in einem Geräteunterteil untergebracht sein. Der Schleifendurchmesser wird genügend groß gewählt, damit die Strömungswiderstände begrenzt und damit die Druckverluste in den die Isolationsstrecken bildenden Leitungen gering gehalten werden können.The connection block 2 'is designed as a metal block, in which a manually operated shut-off valve 11, a water filter 12 and a spring-operated check valve 13 are integrated. Downstream of the connection block 2 'are the control device 3 and Various measuring and control elements common to instantaneous water heaters arranged. In the control device 3 there are TRIACs 31 for separate control of the heating output of the individual heating modules 5a, 5b and 5c provided over the heating coil 50a, 50b and 50. The heating coil 50a-c consist of bare heating resistance wires, which an excellent heat transfer to the ensure heating fluid (water). Are prescribed certain insulation resistances between bare heating coils and the next metallic connection point in the flow path of the water. The fluid lines must be correspondingly long between the respective heating modules 5a and 5c and the connections be on the cold or hot water side. These fluid line paths are shown in the instantaneous water heater through flexible hoses 4 ', 6 made of electrically insulating material educated. On the one hand, these hoses are easy to use couple with appropriate connecting pieces and on the other hand easy and space-saving to lay. For example, you can in loops behind the heating section 5 in a lower part of the device be housed. The loop diameter gets big enough chosen so that the flow resistances are limited and thus the Pressure losses in the lines forming the insulation sections can be kept low.

    Die Erfindung nutzt die durch die flexiblen Leitungen 4, 4' und 6 gewonnene Beweglichkeit aber nicht nur zur platzsparenden Verlegung der Isolationsstrecken, sondern auch zur Variation und Anpassung der Anschlußpositionen der Ein- und Auslässe 2 und 7. Die Lage der Anschlußelemente muß in jedem Falle mit derjenigen des wandseitigen Wasseranschlußmusters übereinstimmen, und zwar so, daß der Kaltwasser-Einlauf 2 auch mit dem Kaltwasseranschluß und der Warmwasser-Auslauf auch mit dem Warmwasseranschluß verbunden wird. Die in Figur 1 dargestellte Relativlage muß also je nach Stellung des elektrischen Durchlauferhitzers verändert und ggf. sogar überkreuzt werden. Hierfür geben die als flexible Schläuche ausgebildeten Leitungen 4 und 6 den notwendigen Bewegungsspielraum. Es ist leicht einzusehen, daß es für die Zwecke der Erfindung, d.h. den Ausgleich und die Anpassung der Einlauf- und Auslauf-Anschlußmuster in vielen Fällen ausreicht, wenn nur eine der Leitungen 4 und 6 flexibel ausgebildet ist. Der andere Anschluß (2) kann sogar gerätefest oder nur geringfügig änderbar sein. Die doppelte Beweglichkeit durch flexible Ausführungen beider Leitungen 4 und 6 ist aber bevorzugt und erhöht die Variationsmöglichkeiten.The invention uses the flexible lines 4, 4 ' and 6 gained mobility but not only to save space Laying the insulation sections, but also for variation and adjustment of the connection positions of the inlets and outlets 2 and 7. The location of the connection elements must in any case with match that of the wall-side water connection pattern, in such a way that the cold water inlet 2 also with the Cold water connection and hot water outlet also with the Hot water connection is connected. The one shown in Figure 1 Relative position must therefore depend on the position of the electric instantaneous water heater changed and possibly even crossed. Therefor give the lines designed as flexible hoses 4 and 6 the necessary freedom of movement. It's easy to see that for the purposes of the invention, i.e. the compensation and the adjustment of the inlet and outlet connection patterns in In many cases it is sufficient if only one of the lines 4 and 6 is flexible. The other connection (2) can even be fixed to the device or only slightly changeable. The double agility through flexible designs of both lines 4 and 6 is preferred and increases the possible variations.

    Die Figuren 2 und 4 zeigen einige äußere Ausgestaltungen und Montagemöglichkeiten, wie sie durch die Erfindung geboten werden.Figures 2 and 4 show some external configurations and mounting options, as offered by the invention will.

    Figur 2 zeigt ein Beispiel für eine Untertischmontage des Durchlauferhitzers 1.

Der Unterteil hat einen falzartig gekröpften umlaufenden Rand 23, auf den der Haubenrand passend aufsteckbar ist. In der der Schnittebene gemäß den Fig. 5A und 5B entsprechenden Mittelebene der Haube 22 sind an diametral gegenüberliegenden Stellen Einschnitte 24 ausgebildet. Im zusammengesetzten Zustand von Unterteil 21 und Haube 22 sind die beiden axial Einschnitte 24 mit-zueinander fluchtenden Bohrungen 25 im falzartigen Rand 23 ausgerichtet. In dem in Fig. 5B dargestellten zusammengebauten Zustand sind in die beiden ausgerichteten Öffnungen 24 und 25 (oben und unten) jeweils Schrauben 26 eingesteckt, die in ein mit Innengewinde versehenes Verbindungselement in Form einer Mutter oder eines Gewinderings 27 eingeschraubt sind. Das Verbindungselement 27 ist in dem dargestellten Ausführungsbeispiel mit dem umlaufenden Rand 23 des Unterteils 21 fest, beispielsweise durch Verkleben oder Verschweißen verbunden.The housing 20 consists of a preferably wall-fixed Lower part 21 and an approximately box-shaped hood 22. The lower part has a crimped peripheral edge 23 on which the hood edge can be plugged on. In the cutting plane 5A and 5B corresponding central plane of the Hood 22 are incisions at diametrically opposite locations 24 trained. In the assembled state of the lower part 21 and hood 22 are the two axial incisions 24 with mutually aligned bores 25 in the rabbet-like edge 23 aligned.
