Description
Elektrisch beheizter Durchlauferhitzer Die Erfindung betrifft einen elektrisch beheizten Durchlauferhitzer mit einem von Hand zu betätigenden Einlaßventil und einem aus isolierendem Werkstoff hergestellten Kanalkörper. Es ist bei solchen Geräten bekannt, den Kanalkörper mit einem Durchlaufkanal und darin gelagerter Heizwendel zu versehen.Electrically heated water heater The invention relates to a electrically heated water heater with a manually operated inlet valve and a channel body made of insulating material. It is with such Devices known, the channel body with a flow channel and heating coil stored therein to provide.
Der Erfindung liegt die Aufgabe zugrunde, die verhältnismäßig langen, als Schutzwiderstand wirkenden Wasserwege in raumsparender Weise anzuordnen und dabei diel elektrische Zuführung zu der im Mittelteil des Durchlaufkanals. liegenden Heizwendel in einfacher und sicherer Weise zu verlegen.The invention is based on the object of the relatively long, to arrange waterways acting as protective resistance in a space-saving manner and thereby the electrical supply to the in the middle part of the flow channel. lying Laying the heating coil in a simple and safe way.
Erfindungsgemäß. wird das dadurch erreicht, daß der Durchlaufkanal aus drei konzentrisch um das Einlaßventil angeordneten kreisbogenförmigen, einander umgreifenden Kanalabschnitten besteht, die durch Querkanäle miteinander verbunden sind, und daß in dem mittleren, verbreiterten Abschnitt die Heizwendel angeordnet ist.According to the invention. this is achieved in that the flow channel of three circular arcs arranged concentrically around the inlet valve, each other encompassing channel sections, which are connected to one another by transverse channels are, and that the heating coil is arranged in the central, widened section is.
Es kann daher ein flacher vorzugsweise scheibenförmiger Kanalkörper verwendet werden, und die elektrischen Zuleitungen. können zwischen den Querkanälen ohne Überbrückung des Durchlaufkanals zur Heizwendel geführt werden.It can therefore be a flat, preferably disk-shaped, channel body are used, and the electrical leads. can between the transverse channels be guided to the heating coil without bridging the flow channel.
Zweckmäßigerweise sind die als Aussparungen des Kanalkörpers gebildeten Kanalabschnitte durch eine aus isolierendem Werkstoff hergestellten Grundplatte abgedeckt.Appropriately, are formed as recesses in the channel body Channel sections through a base plate made of insulating material covered.
Bei einem solchen Aufbau kann der Kanalkörper aus einem mit Aussparungen versehenen; Kunststoffpreßteil bequem und ohne Schwierigkeiten. hergestellt werden.With such a structure, the channel body can consist of one with recesses provided; Plastic molded part conveniently and without difficulty. getting produced.
Ein Ausführungsbeispiel der Erfindung ist in der Abbildung schematisch dargestellt.An embodiment of the invention is shown schematically in the figure shown.
In einem kreisrunden scheibenförmigem Isolierstoffkörper 1 ist zentrisch eine Einlaßöffnung 2 angebracht, die durch ein nicht dargestelltes Einlaßventil beherrscht ist. Im Isolierstoffkörper 1 sind ferner Kanalaussparungen vorgesehen, die als drei konzentrisch um das Einlaßventil angeordnete kreisbogenförmige, einander umgreifende Kanalabschnitte 3, 4, 5 ausgebildet sind. Die Kanalabschnitte 3, 4, 5 sind; durch Querkanäle 6, 7 miteinander verbunden. Im verbreiterten mittleren Teil 4' des mittleren Kanalabschnittes 4 ist eine Heizwendel 8, die unmittelbar im Wasserstrom liegt, angeordnet. Der innere Kanalabschnitt 3 besitzt einen radial verlaufenden Fortsatz 9, der über das Einlaßventil mit der Einlaßöffnung 2 in Verbindung steht. Der äußere Kanalabschnitt 5 ist an eine Auslaßleitung 10 angeschlossen. Die Kanalaussparungen sind durch eine den Kanalkörper 1 völlig abdeckende, nicht dargestellte Grundplatte abgeschlossen, so daß ein nach außen abgedichteter Durchlaufkanal entsteht. Die Wassersäulen des äußeren, 5, und des, inneren: Kanalabschnittes 3 wirken als Schutzwiderstände, damit an die Heizwendel 8 ohne Gefahr eine Spannung angelegt werden kann. Die elektrischen Zuleitungen zur Heizwendel 8 können zwischen den Querkanälen 6, 7 so, verlegt werden, da.ß sie den Durchlaufkanal nicht zu überbrücken brauchen.In a circular, disk-shaped insulating body 1, an inlet opening 2 is mounted centrally, which is dominated by an inlet valve (not shown). In the insulating body 1, channel recesses are also provided, which are designed as three circular arc-shaped channel sections 3, 4, 5 that encompass one another and are arranged concentrically around the inlet valve. The channel sections 3, 4, 5 are; Interconnected by transverse channels 6, 7. In the widened central part 4 'of the central channel section 4, a heating coil 8, which is located directly in the water flow, is arranged. The inner channel section 3 has a radially extending extension 9 which is connected to the inlet opening 2 via the inlet valve. The outer channel section 5 is connected to an outlet line 10. The channel recesses are closed off by a base plate (not shown) which completely covers the channel body 1, so that a flow channel is formed that is sealed off from the outside. The water columns of the outer, 5, and the, inner: channel section 3 act as protective resistors so that a voltage can be applied to the heating coil 8 without danger. The electrical leads to the heating coil 8 can be laid between the transverse channels 6, 7 in such a way that they do not need to bridge the flow channel.
