Description

Heißwasserarmatur mit isoliertem Auslauf Hot water tap with insulated spout
Die Erfindung betrifft eine Armatur, insbesondere eine Heißwasserarmatur zum Zapfen von Wasser mit einer Temperatur von über 60° gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a fitting, in particular a hot water fitting for tapping water with a temperature of about 60 ° according to the preamble of patent claim 1.
Neben Mischwasser- und Thermostatarmaturen sind Heißwasserarmaturen bekannt, die insbesondere kleine Mengen von Wasser oder Wasserdampf mit Temperaturen bis zu 110 ° C abgeben. Die letztgenannten kommen vor allem in Küchen zum Einsatz, wo heißes oder kochendes Wasser speziell in kleinen Mengen zum Brühen von Tee, Kaffee, Pochieren oder ähnlichem verwendet wird. Da aufgrund der hohen Temperaturen die Gefahr von Verbrühungen besteht, ist es erforderlich derartige Armaturen mit bestimmten Sicherungseinrichtungen zu versehen.In addition to mixing water and thermostatic valves hot water fittings are known, in particular, deliver small amounts of water or steam at temperatures up to 110 ° C. The latter are mainly used in kitchens, where hot or boiling water is used especially in small quantities for brewing tea, coffee, poaching or the like. Since the risk of scalding due to the high temperatures, it is necessary to provide such fittings with certain security devices.
Da gerade in Küchen der Auslauf oft beim Füllen eines Gefäßes gedreht und somit angefasst wird, besteht gerade beim Zapfen von heißem Wasser die Gefahr, sich beim Berühren des Auslaufs zu verbrennen.Especially in kitchens, the spout is often turned and thus touched when filling a vessel, especially when hot water is being tapped there is a risk of burning when the spout is touched.
Aus der EP 0 792 970 Al ist beispielsweise eine Heißwasserarmatur bekannt, deren Auslauf mit einem wärmeisolierenden Material ausgekleidet ist. Aufgabe der Erfindung ist es, eine Armatur bereitzustellen, bei der auch bei hohen Wassertemperaturen keine Gefahr von Verbrennungen beim Berühren besteht.From EP 0 792 970 A1, for example, a hot water fitting is known, whose outlet is lined with a heat-insulating material. The object of the invention is to provide a fitting in which there is no risk of burns when touching even at high water temperatures.
Diese Aufgabe wird von einer Armatur mit den Merkmalen des Patentanspruchs 1 erfüllt. Vorteilhafte Weiterbildungen sind Gegenstand der Unteransprüche.This object is achieved by a fitting having the features of patent claim 1. Advantageous developments are the subject of the dependent claims.
Mit der Erfindung wird eine Armatur, insbesondere eine Heißwasserarmatur zum Zapfen von Wasser mit einer Temperatur von über 60° C, mit einem um eine vertikale Achse drehbaren Auslauf, der eine eine Wasserführung umgebende Außenhülle umfasst und ein Absperr- und/oder Mischventil aufweist, wobei die Wasserführung mit einer Auslauföffnung des Absperr- und/ oder Mischventils verbunden ist, bei der die Wasserführung im Auslauf mit Abstand zur Außenhülle angeordnet ist, wobei im Zwischenraum zwischen Wasserführung und Außenhülle des Auslaufs eine Isolierschicht aus Luft eingeschlossen ist. Damit ist die Wasserführung von der Außenhülle des Auslaufs thermisch entkoppelt, so dass es keinen Wärmeübergang aufgrund von Wärmeleitung geben kann.With the invention, a fitting, in particular a hot water fitting for tapping water at a temperature of about 60 ° C, with a rotatable about a vertical axis spout, which comprises a surrounding a water guide outer shell and having a shut-off and / or mixing valve, wherein the water guide is connected to an outlet opening of the shut-off and / or mixing valve, wherein the water supply is arranged in the outlet at a distance from the outer shell, wherein in the space between the water guide and outer shell of the outlet an insulating layer of air is included. Thus, the water supply is thermally decoupled from the outer shell of the outlet, so that there can be no heat transfer due to heat conduction.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist die Wasserführung dabei aus einem flexiblen Schlauch vorgesehen. Dies ermöglicht es, den Schlauch flexibel jeder Auslaufform anpassen zu können.According to an advantageous embodiment of the invention, the water supply is provided from a flexible hose. This makes it possible to flexibly adapt the hose to any outlet shape.
Bevorzugt besteht der Schlauch aus einem Silikon oder einem anderen synthetischen Polymer, das eine hohe Wärmebeständigkeit aufweist. Weiterhin eignet sich auch Polyterafluoretylen (PTFE oder Teflon) oder ein Thermoplast mit ähnlichen Eigenschaften. Zur Verstärkung der Wasserführung oder des Schlauchs kann zusätzlich eine Ummantelung aus Edelstahl oder Kunststoffgewebe angeordnet werden kann. Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im Folgenden näher beschrieben. Es zeigt in den ZeichnungenPreferably, the tube is made of a silicone or other synthetic polymer which has high heat resistance. Also suitable is polyterfluoroethylene (PTFE or Teflon) or a thermoplastic with similar properties. To reinforce the water supply or the hose can be arranged in addition a sheath made of stainless steel or plastic fabric. An embodiment of the invention is illustrated in the drawing and will be described in more detail below. It shows in the drawings
Figur 1 eine erfindungsgemäße Armatur im Schnitt; Figur2 einen Schnitt durch Figur 1 entlang der Linie 2-2.Figure 1 shows a fitting according to the invention in section; FIG. 2 shows a section through FIG. 1 along the line 2-2.
Figur 1 zeigt einen Schnitt durch eine Armatur zum Zapfen von Heißwasser. An einem Armaturenkörper 4 ist ein Auslauf 6 über einen Einsatz 5 drehbar befestigt. Von einem Heißwasserbereiter oder Boiler (nicht dargestellt) führt eine Wasserzuleitung 1 zu einer Wassereinlassöffnung eines Absperrventils 2. Von der Wasserauslassöffnung des Absperrventils 2 ist wiederum eine Wasserführung 3 in Form eines flexiblen Schlauchs bis zum Strahlbildner 7 am Ende des Auslaufs 6 angeordnet.Figure 1 shows a section through a valve for tapping hot water. On a fitting body 4, an outlet 6 is rotatably mounted via an insert 5. From a hot water heater or boiler (not shown), a water supply line 1 leads to a water inlet opening of a shut-off valve 2. From the water outlet opening of the shut-off valve 2 in turn a water guide 3 in the form of a flexible hose to the jet former 7 at the end of the outlet 6 is arranged.
Figur 2 zeigt im Schnitt durch die Heißwasserarmatur aus Figur 1 einen Griff 9, der zur Betätigung des Absperrventils 2 vorgesehen ist. Die Griffhüllen derartiger Griffe 9 bestehen üblicherweise aus einem Kunststoffmaterial, so dass die Spindel des Absperrventils 2 ausreichend gegenüber dem Benutzer isoliert ist.Figure 2 shows in section through the hot water fitting of Figure 1, a handle 9 which is provided for actuating the shut-off valve 2. The grips of such handles 9 are usually made of a plastic material, so that the spindle of the shut-off valve 2 is sufficiently insulated from the user.
Als Befestigungseinrichtung 8 ist üblicherweise ein Gewindestange oder ähnliches mit zugehöriger Verschraubung vorgesehen, mittels derer die Heißwasserarmatur einer Armaturenbank oder Arbeitsplatte fixiert werden kann.As a fastening device 8 usually a threaded rod or the like is provided with associated screw, by means of which the hot water fitting a tap bank or countertop can be fixed.
Da der Auslauf 6 beim Verschwenken an vielen verschiedenen Stellen ange- fasst werden kann, ist es notwendig, über dessen gesamte Länge für eine ausreichende Wärmeisolierung zu sorgen. Daher ist der flexible Schlauch von der Befestigungssteüε des Auslaufs 6 bis zum Strahlbiidner 7 bzw., dem Wasseraustritt mit Abstand zur Auslaufaußenhülle angeordnet, wodurch dieser von der Wasserführung 3 thermisch entkoppelt ist. Aufgrund der isolierenden Luftschicht zwischen Schlauch und Auslauf 6 kann es nicht zur direkten Wärmeübertragung kommen. BezugszeichenlisteSince the spout 6 can be handled at many different points during pivoting, it is necessary to ensure sufficient thermal insulation over its entire length. Therefore, the flexible hose from the Befestigungssteüε of the outlet 6 to the Strahlbiidner 7 or, the water outlet arranged at a distance from the outlet outer shell, whereby it is thermally decoupled from the water supply 3. Due to the insulating air layer between the hose and outlet 6, it can not come to direct heat transfer. LIST OF REFERENCE NUMBERS
