Description

Die Erfindung betrifft ein sanitäres Mischventil mit einem metallischen, gegossenen Ventilgehäuse, das eine Kaltwasser-Einlaßbohrung, eine Warmwasser-Einlaßbohrung und eine Mischwasser-Auslaßöffnung aufweist und in dem von der Kaltwasser-Einlaßöffnung ein Kaltwasserweg ausgeht, der an einer Vereinigungsstelle von Kalt- und Warmwasser mit einem Warmwasserweg zusammengeführt ist, der von der Warmwasser-Einlaßbohrung ausgeht.The invention relates to a sanitary mixing valve a metallic, cast valve body, the one Cold water inlet hole, a hot water inlet hole and has a mixed water outlet opening and in the a cold water path starts from the cold water inlet opening, who at a union of cold and Hot water is merged with a hot water path, starting from the hot water inlet hole.

Derartige sanitäre Mischventile sind in großer Vielzahl bekannt. So befinden sich beispielsweise Thermostatventile auf dem Markt, bei welchen sich die Vereinigungsstelle von Warm- und Kaltwasser innerhalb eines Thermostatgliedes befindet, das in das Ventilgehäuse eingesetzt bzw. eingeschraubt ist. Die wasserführenden Räume innerhalb des Ventilgehäuses werden im wesentlichen durch gegossene, metallische innere und äußere Wände des Ventilgehäuses begrenzt. Sofern nun, wie dies insbesondere bei Thermostatventilen häufig ist, der Warmwasserweg innerhalb des Ventilgehäuses eine erhebliche Länge besitzt, bevor die Vereinigung mit dem Kaltwasser erfolgt, kann dies dazu führen, daß sich das Ventilgehäuse in einem derartigen Ausmaße an seiner Außenfläche erwärmt, daß es zu Verbrennungen des Benutzers oder zumindest zu Schreckreaktionen kommt.Such sanitary mixing valves are available in large numbers known. For example, there are thermostatic valves on the market where the association is located of hot and cold water within a thermostat element located in the valve body or screwed in. The water-bearing spaces inside of the valve body are essentially by cast, metallic inner and outer walls of the valve body limited. If so, as is the case with Thermostatic valves are common to the hot water path inside of the valve housing has a considerable length before the combination with the cold water takes place, this can cause the valve housing in such Dimensions on its outer surface warmed that it could cause burns of the user or at least to startle reactions is coming.

Aufgabe der vorliegenden Erfindung ist es, ein sanitäres Mischventil der eingangs genannten Art derart auszugestalten, daß eine unzulässig hohe Erwärmung des Ventilgehäuses nicht mehr auftritt.The object of the present invention is a sanitary To design the mixing valve of the type mentioned at the outset, that an impermissibly high heating of the valve housing no longer occurs.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Warmwasserweg zumindest auf dem überwiegenden Teil seiner Längserstreckung einen von Mischwasser durchströmten Raum durchsetzt.This object is achieved in that the warm water path at least for the most part its longitudinal extent one with mixed water flowing through it Space interspersed.

Bei der vorliegenden Erfindung liegt zwischen dem Warmwasserweg und der Außenwand des Ventilgehäuses selbst ein von Mischwasser durchströmter Raum, der den Warmwasserweg isoliert und so eine Überhitzung des Ventilgehäuses vermeidet. Es werden also nicht mehr sämtliche Wasserwege durch an das Gehäuse angeformte äußere Gußwände begrenzt. Auf diese Weise sind Verbrennungen oder Schreckreaktionen des Benutzers des sanitären Mischventiles nicht mehr zu erwarten.In the present invention lies between the hot water path and the outer wall of the valve housing itself a room through which mixed water flows, which is the hot water path isolated and so overheating of the valve housing avoids. So there are no longer all waterways limited by molded outer walls on the housing. In this way there are burns or startling reactions of the user of the sanitary mixing valve no longer expect.

Eine vorteilhafte Ausführungsform der Erfindung zeichnet sich dadurch aus, daß der Warmwasserweg innerhalb des Ventilgehäuses zumindest überwiegend von einem Rohr oder Schlauch aus schlecht wärmeleitendem Material gebildet ist. Dieses läßt aufgrund seiner schlechten Wärmeleitfähigkeit eine Abgabe von Wärme aus dem Warmwasser an das umgebende Mischwasser und von dort an das Ventilgehäuse nur begrenzt zu. Die kurzen Wegstrecken, auf welchen das Warmwasser, z.B. im Bereich der Warmwasser-Einlaßöffnung, noch durch das Material des Ventilgehäuses selbst strömt, reichen zu einer unzulässig hohen Erwärmung des Ventilgehäuses nicht mehr aus.An advantageous embodiment of the invention is characterized is characterized in that the hot water path within the Valve housing at least predominantly from a pipe or Hose made of poorly heat-conducting material is. This leaves due to its poor thermal conductivity a transfer of heat from the hot water to the surrounding mixed water and from there to the valve housing only limited to. The short distances on which that Hot water, e.g. in the area of the hot water inlet opening, still flows through the material of the valve housing itself, suffice for an inadmissibly high heating of the valve housing no longer out.

Zweckmäßigerweise besteht das Rohr bzw. der Schlauch aus Kunststoff.The pipe or the hose expediently exists made of plastic.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnung näher erläutert; die einzige Figur zeigt den Axialschnitt durch ein Thermostatventilgehäuse.An embodiment of the invention is as follows explained in more detail with reference to the drawing; the only figure shows the axial section through a thermostatic valve housing.

Das in der Zeichnung dargestellte Thermostatventilgehäuse 1 ist ein im wesentlichen zylindrisches Messinggußteil, welches eine Einlaßbohrung 2 für Kaltwasser und eine Einlaßbohrung 3 für Warmwasser aufweist. Die Einlaßbohrungen 2, 3 sind im Betrieb des Thermostatventils mit den entsprechenden Hausleitungen verbunden.The thermostatic valve housing shown in the drawing 1 is an essentially cylindrical cast brass part, which has an inlet bore 2 for cold water and a Has inlet bore 3 for hot water. The inlet holes 2, 3 are in operation with the thermostatic valve connected to the corresponding house management.

Die Kaltwasser-Einlaßbohrung 2 steht mit einem ringförmigen Kaltwasser-Verteilraum 4 in Verbindung, der seinerseits wieder mit einer gestuften, sich zur rechten Stirnseite des Thermostatventilgehäuses 1 öffnenden Aufnahmebohrung 5 für das Thermostat-Regelglied kommuniziert.The cold water inlet bore 2 is ring-shaped Cold water distribution room 4 in connection, which in turn again with a stepped, to the right End of the thermostatic valve housing 1 opening Receiving hole 5 for the thermostat control element communicates.

Die Warmwasser-Einlaßbohrung 3 steht mit einem Rohr 6 aus schlecht wärmeleitendem Material, beispielsweise Kunststoff, in Verbindung, dessen in der Zeichnung linkes Ende in eine Bohrung 8 einer Gehäusewandung 9 eingeschoben ist. Das Rohr 6 ist gegen die Bohrung 8 der Gehäusewandung 9 durch einen O-Ring 10 abgedichtet. In entsprechender Weise ist das in der Zeichnung rechte Ende des Rohres 6 in eine Bohrung 11 einer Gehäusewandung 12 eingeschoben und gegen diese durch einen O-Ring 13 abgedichtet.The hot water inlet bore 3 is with a tube 6 made of poorly heat-conducting material, for example Plastic, in connection, whose left in the drawing End inserted into a bore 8 of a housing wall 9 is. The tube 6 is against the bore 8 of the housing wall 9 sealed by an O-ring 10. In corresponding Way is the right end of the drawing Tube 6 into a bore 11 of a housing wall 12 inserted and sealed against this by an O-ring 13.

Die Bohrung 11 in der Gehäusewandung 12 steht mit einem ringförmigen Wasserverteilraum 14 für Warmwasser in Verbindung, der in axialem Abstand zum Kaltwasserverteilraum 4 ebenfalls mit der Aufnahmebohrung 5 für das Thermostatglied kommuniziert. Das aus Übersichtlichkeitsgründen in der Zeichnung nicht dargestellte Thermostatglied ist so ausgebildet, daß es nach dem Einschrauben in die Aufnahmebohrung 5 das Kaltwasser aus dem Kaltwasser-Verteilraum 4 sowie das Warmwasser aus dem Warmwasser-Verteilraum 14 getrennt aufnehmen und, entsprechend einer an einem Handgriff vorwählbaren Solltemperatur, in axialer Richtung, in der Zeichnung nach links, abgeben kann. Der Aufbau derartiger Thermostatglieder ist an und für sich bekannt; auf eine Beschreibung kann daher hier verzichtet werden.The bore 11 in the housing wall 12 is with a annular water distribution space 14 for hot water in Connection that is at an axial distance from the cold water distribution room 4 also with the mounting hole 5 for the thermostat element communicates. For reasons of clarity Thermostat element not shown in the drawing is designed so that after screwing in the receiving hole 5 the cold water from the cold water distribution room 4 and the hot water from the hot water distribution room 14 record separately and, accordingly a target temperature that can be preselected on a handle, Deliver in the axial direction, to the left in the drawing can. The construction of such thermostatic elements is on and known for itself; can therefore on a description to be dispensed with here.

Die Aufnahmebohrung 5 für das Thermostatglied führt im Inneren des Thermostatventilgehäuses 1 zu einem Mischwasser-Überführungsraum 15, der von dem oben beschriebenen schlecht wärmeleitenden Rohr 6 durchsetzt wird. An dem der Aufnahmebohrung 5 für das Thermostatglied gegenüberliegenden, in der Zeichnung linken Ende steht der Mischwasser-Überführungsraum 15 mit einer Aufnahmebohrung 16 für ein Mengenregulierventil 17 in Verbindung. Das Mengenregulierventil 17 ist anders als das Thermostatglied in der Zeichnung schematisch dargestellt. Es umfaßt als Steuerelemente für den Wasserstrom koaxiale, zueinander verdrehbare Keramikscheiben, wie dies an und für sich bekannt ist. Die Zulauföffnung des Mengenregulierventiles 17 befindet sich axial mittig an dem dem Mischwasser-Überführraum 15 zugewandten Ende des Aufnahmeraumes 16; die Auslaßöffnung 18 des Mengenregulierventils 17 ist ebenfalls axial gerichtet, jedoch außermittig positioniert. Auf diese Weise kommuniziert die Auslaßöffnung 18 des Mengenregulierventils 17 mit einem Mischwasser-Auslaufraum 19, der von dem Mischwasser-Überführungsraum 15 durch eine Gehäusewand 20 getrennt ist und zu einer Auslauföffnung 21 des Thermostatventilgehäuses 1 führt. Die Auslauföffnung 21 ist dann in an und für sich bekannter Weise mit einer Auslaufarmatur oder einer Brause verbunden.The receiving hole 5 for the thermostat member leads inside the thermostatic valve housing 1 to a mixed water transfer room 15, of that described above bad heat-conducting tube 6 is penetrated. At the opposite of the receiving bore 5 for the thermostatic element, in the left end of the drawing is the Mixed water transfer room 15 with a receiving hole 16 for a flow control valve 17 in connection. The quantity regulating valve 17 is different from the thermostatic element shown schematically in the drawing. It includes coaxial controls for the water flow, ceramic disks rotatable relative to one another, such as this and is known for itself. The inlet opening of the flow control valve 17 is axially centered on the the mixed water transfer space 15 facing the end of Receiving space 16; the outlet opening 18 of the flow control valve 17 is also axially directed, however positioned off-center. Communicates this way the outlet opening 18 of the volume control valve 17 with a mixed water discharge space 19 which is from the mixed water transfer space 15 separated by a housing wall 20 and to an outlet opening 21 of the thermostatic valve housing 1 leads. The outlet opening 21 is then in in a manner known per se with an outlet fitting or a shower connected.

Die Funktionsweise des Thermostatventiles, welches aus dem in Figur 1 gezeigten Thermostatventilgehäuse 1 durch Einschrauben des Thermostatgliedes in die Aufnahmebohrung 5 erhalten wird, ist folgende:The functioning of the thermostatic valve, which consists of through the thermostatic valve housing 1 shown in FIG Screw the thermostat element into the mounting hole 5 is obtained is the following:

Das aus der Hausleitung kommende Kaltwasser wird von der Kaltwasser-Einlaßbohrung 2 in den Kaltwasser-Verteilraum 4 geführt und von dort entsprechend der Stellung des Thermostatregelgliedes dem Warmwasser beigemischt, welches über die Warmwasser-Einlaßbohrung 3, das Rohr 6 und den Warmwasser-Verteilraum 14 zuströmt. Das in axialer Richtung in den Mischwasser-Überführungsraum 15 strömende Mischwasser befindet sich dann idealerweise auf der an dem Handgriff des Thermostatgliedes eingestellten Solltemperatur. Das Mischwasser fließt aus dem Mischwasser-Überführungsraum 15 entsprechend der Stellung der Keramikscheiben innerhalb des Mengenregulierventiles 17 in den Mischwasser-Auslaufraum 19, von dort zur Auslauföffnung 21 und zu dem hieran angeschlossenen Verbraucher.The cold water coming from the house management is from the cold water inlet bore 2 in the cold water distribution room 4 out and from there according to the position the thermostat control element is mixed with the hot water, which via the hot water inlet bore 3, the pipe 6 and the hot water distribution chamber 14 flows. This in axial direction in the mixed water transfer space 15 flowing mixed water is then ideally on the on the handle of the thermostat link set target temperature. The mixed water flows from the mixed water transfer space 15 accordingly the position of the ceramic discs within the flow control valve 17 into the mixed water outlet space 19, from there to the outlet opening 21 and to this connected consumers.

Aufgrund der Tatsache, daß das Warmwasser auf dem größten Teil des Wegs durch das Thermostatventilgehäuse 1 nicht in direkter Berührung mit dessen gut wärmeleitendem Material steht sondern statt dessen durch den Mischwasser-Überführungsraum 15 und das schlecht wärmeleitende Rohr 6 isoliert ist, kann sich das Thermostatventilgehäuse 1 nur verhältnismäßig wenig erwärmen. Die Außenfläche des Thermostatventilgehäuses 1 bleibt daher verhältnismäßig kühl; eine Verbrennungsgefahr bei einer Berührung besteht nicht mehr.Due to the fact that the hot water is at its greatest Part of the way through the thermostatic valve housing 1 not in direct contact with its good thermal conductivity Instead, material stands through the mixed water transfer room 15 and the poorly heat-conducting pipe 6 is insulated, the thermostatic valve housing 1 heat up relatively little. The outer surface of the Thermostat valve housing 1 therefore remains proportionate cool; there is a risk of burns when touched no more.
