Description

Gegenstand der ErfindungSubject of the invention

Die vorliegende Erfindung betrifft einen sanitären Warmwasserboiler, umfassend einen thermisch isolierten, zylindrischen Vorratsbehälter, ausgerüstet mit einer Wasserzuleitung im unteren Bereich und einem Auslassrohr zur Entnahme des Wassers im oberen Bereich des Vorratsbehälters.The present invention relates to a sanitary hot water boiler, comprising a thermally insulated, cylindrical reservoir, equipped with a water supply line in the lower region and an outlet pipe for removing the water in the upper region of the reservoir.

Stand der TechnikState of the art

Sanitäre Warmwasserboiler der oben geschilderten Art sind bekannt. Sie dienen dazu, das warme Wasser bei der Gebrauchstemperatur zu speichern, um einen schwachen Warmwasserverbrauch abzudecken, ohne dass die unmittelbare Inbetriebnahme des Heizkessels notwendig wird, der nur dazu dient, das Wasser bis zur Gebrauchstemperatur wieder aufzuwärmen, oder im Fall eines starken Verbrauchs darüber hinaus das Wasser direkt auf Betriebstemperatur zu erwärmen, wenn der Vorrat im Warmwasserboiler verbraucht ist.Sanitary hot water boiler of the type described above are known. They serve to store the warm water at the service temperature to cover a low consumption of hot water, without requiring the immediate start-up of the boiler, which only serves to reheat the water to the service temperature, or in case of heavy consumption beyond to heat the water directly to operating temperature when the supply in the boiler is used up.

Eine derartige Vorrichtung eines Warmwasserboilers ist beispielsweise in dem Dokument DE 10 2005 024 051 A1 beschrieben, das die unterschiedlichen Kreisläufe des Erwärmens und des Wiederaufwärmens des Wassers sowie die Arten der Entnahme aufzeigt. Aus Platzgründen in der Höhe umfasst die Vorrichtung mehrere parallel oder in Reihe angeordnete Warmwasserboiler.Such a device of a hot water boiler is for example in the document DE 10 2005 024 051 A1 describing the different cycles of heating and reheating the water, as well as the types of extraction. For reasons of space in height, the device comprises a plurality of parallel or in series arranged hot water boiler.

Das allgemeine Problem des Speicherns von Wasser in einem sanitären Warmwasserboiler besteht in der Zufuhr des Wassers, das nach und nach das entnommene Wasser ersetzt und die Schichtenbildung des warmen Wassers im Boiler stört. Denn die Zufuhr des Wassers findet im unteren Bereich statt und durch seine Turbulenzen bewegt sich das Wasser aufgrund der kinetischen Energie nach oben und zerstört die Schichtenbildung.The general problem of storing water in a sanitary hot water boiler is the supply of water, which gradually replaces the extracted water and disturbs the stratification of the warm water in the boiler. Because the supply of water takes place in the lower area and by its turbulence, the water moves upwards due to the kinetic energy and destroys the stratification.

Es ist bekannt, den Strahl des einströmenden Wassers am Einlass des Vorratsbehälters aufzuspalten, um den Strahl abzulenken und ihn seitlich aufzufächern, um diese Turbulenzen zu vermeiden oder zumindest zu vermindern. Eine derartige Vorrichtung ist aus Dokument DE-U1-92 12 049 schon bekannt. Jedoch besitzt das Wasser die Neigung, entlang der Wand des Vorratsbehälters aufzusteigen und eine turbulente Strömung zu erzeugen, die nach wie vor die Schichtenbildung des warmen Wassers stört, selbst wenn diese Störung geringer ist als die eines direkten Strahls.It is known to split the jet of incoming water at the inlet of the reservoir to deflect the jet and laterally fan it out to avoid or at least reduce this turbulence. Such a device is from document DE-U1-92 12 049 already known. However, water tends to rise along the wall of the reservoir and create a turbulent flow that still interferes with stratification of the warm water, even if this disturbance is less than that of a direct jet.

Es ist bekannt, Schikanen auf der Innenwand des Vorratsbehälters zu fixieren, um diese Störung zu vermindern. Jedoch sind diese Schikanen, die sicherlich die turbulente Strömung entlang der Wand des Vorratsbehälters vermindern, eine kostspielige Lösung aufgrund des Arbeitsaufwands für die Befestigung der Schikanen auf den Innenwand des Vorratsbehälters durch Schweißen.It is known to fix baffles on the inner wall of the reservoir in order to reduce this disturbance. However, these baffles, which certainly reduce the turbulent flow along the wall of the reservoir, are a costly solution due to the labor required to secure the baffles to the inner wall of the reservoir by welding.

Aufgabe der ErfindungObject of the invention

Die vorliegende Erfindung hat die Aufgabe einen sanitären Warmwasserboiler zu entwickeln, der einen Betrieb ohne Störung der Schichtenbildung des Warmwassers durch die Zufuhr des Wassers am Boden des Vorratsbehälters im Augenblick der Entnahme des Wassers im oberen Bereich oder beim Zirkulieren des Wassers im Behälter aufgrund seines Wiederaufwärmens erlaubt oder diese auf ein Minimum reduziert.The present invention has an object to provide a sanitary hot water boiler, which allows operation without disturbing the stratification of the hot water by the supply of water at the bottom of the reservoir at the moment of removal of the water at the top or when circulating the water in the container due to its reheating or reduced to a minimum.

Die Erfindung bezieht sich auf einen sanitären Warmwasserboiler, der hier nicht bildlich dargestellt ist, mit einer senkrechten Achse und einem üblicherweise kreisförmigen Querschnitt. Dieser thermisch isolierte Vorratsbehälter ist im unteren Bereich mit einem Verteilerbehälter mit einem Wassereinlass und einem Wasserauslass ausgerüstet. Der Wasserauslass ist mit einem Auslassrohr versehen, das beim Verlassen des Verteilerbehälters nach oben bis nahe zur inneren Spitze des zylindrischen Vorratsbehälters führt, um dort das warme Wasser zu entnehmen. Der Vorratsbehälter und das Auslassrohr sind in den Zeichnungen nicht wiedergegeben, es erscheinen lediglich der Verteilerbehälter N und der Hut C, der den Wassereinlass im Verteilerbehälter abdeckt.The invention relates to a sanitary hot water boiler, which is not shown here, with a vertical axis and a usually circular cross-section. This thermally insulated storage tank is equipped at the bottom with a distribution tank with a water inlet and a water outlet. The water outlet is provided with an outlet pipe which, when leaving the distributor tank, leads up to near the inner tip of the cylindrical tank to remove the warm water there. The reservoir and the outlet pipe are not shown in the drawings, there appear only the header tank N and the hat C, which covers the water inlet in the header tank.

Gemäß den Figuren 1 und 2 ist der Verteilerbehälter N ein die Form eines Topfes aufweisendes Gebilde aus einem spritzgegossenen Kunststoff, das ein zylindrisches Gehäuse 100 mit einem im allgemeinen runden, dem Eingang des Vorratsbehälters, der auf dem Flansch 101 angeordnet ist, der das zylindrische Gehäuse 100 im oberen Bereich umrandet, angepassten Abschnitt umfasst.According to the FIGS. 1 and 2 the distribution container N is an injection molded plastic mold having a cylindrical housing 100 with a generally round, inlet of the reservoir disposed on the flange 101 surrounding the cylindrical housing 100 at the top, adapted section includes.

Das zylindrische Gehäuse bildet mit seinem Boden eine Vorkammer für den Wassereintritt in den Vorratsbehälter. Der Boden wird durch die Wand 111 der Wassereinlassleitung 110 und die Wand 121 des Wasserauslassleitung 120 gebildet. Die beiden Wände 111, 121 sind über ein den Boden komplettierendes Flächenelement 102 miteinander verbunden. Die beiden Leitungen 110, 120 besitzen vorzugsweise parallele Achsen und sind senkrecht zur vertikalen ZZ-Achse des Verteilerbehälters angeordnet. Die Leitungen sind an den beiden Enden offen und derart mit Anschlussvorrichtungen versehen, dass sich verschiedene Möglichkeiten der Verzeigung mit den übrigen Bereichen der Vorrichtung zur sanitären Aufbereitung von Warmwasser eröffnen.The cylindrical housing forms with its bottom an antechamber for the entry of water into the reservoir. The bottom is formed by the wall 111 of the water inlet duct 110 and the wall 121 of the water outlet duct 120. The two walls 111, 121 are connected to one another via a surface element 102 which completes the floor. The two lines 110, 120 preferably have parallel axes and are arranged perpendicular to the vertical ZZ-axis of the header tank. The lines are open at the two ends and provided with connection devices that open up various ways of Verstelleigung with the other areas of the device for sanitary treatment of hot water.

Ein Auslassstutzen 140 ist seitlich versetzt in dem Hohlraum angeordnet und ist wechselseitig mit der Wand des Gehäuses 100 und mit dem Bereich 121 der Entnahmeleitung 120 verbunden, den er überlappt und mit dem er in Wirkverbindung steht.An outlet port 140 is laterally offset within the cavity and is mutually connected to the wall of the housing 100 and to the portion 121 of the extraction conduit 120 which it overlaps and engages.

Der Verteilerbehälter N weist gleichermaßen einen zylindrischen Wassereinlassstutzen 130 mit einer ovalen Abschnitt auf; dieser zentrale Stutzen 130 ist auf der ZZ-Achse des Verteilerbehälters N angeordnet und trifft seitlich auf die Wassereinlassleitung 110. Diese zur Wasserauslassleitung 120 parallele Wassereinlassleitung 110 bildet gleichermaßen einen Bereich des Bodens des Hohlraums des Verteilerbehälters. Auf ihr ist der zentrale Wassereinlassstutzen 110 aufgesetzt mit sie in Wirkverbindung steht.The header tank N also has a cylindrical water inlet port 130 with an oval section; this central port 130 is located on the ZZ-axis of the header tank N and impinges laterally on the water inlet duct 110. This water inlet duct 110 parallel to the water outlet duct 120 likewise forms a portion of the bottom of the cavity of the header tank. On her the central water inlet port 110 is placed with it in operative connection.

Im Bereich seiner oberen Kante weist der zentrale Stutzen 130, der den Hut aufnimmt, der in den Figuren 1 und 2 nicht gezeigt wird, auf den beiden Seiten zwei Widerlager 131 zum Einclipsen auf.In the area of its upper edge, the central socket 130, which receives the hat, in the FIGS. 1 and 2 not shown, on the two sides of two abutment 131 for clipping on.

Übereinkommensgemäß soll die Richtung der beiden Wasserleitungen des Verteilerbehälters die Längsrichtung sein und die Richtung senkrecht dazu soll die Querrichtung sein.According to the agreement, the direction of the two water pipes of the distribution tank should be the longitudinal direction and the direction perpendicular to it should be the transverse direction.

Der Rand des Flansches 101, der das zylindrische Gehäuse 100 des Verteilerbehälters umrandet, ist mit einer bestimmten Anzahl an Schraubenschächten 150 versehen, d.h. mit zylindrischen Einheiten, die in der Struktur des Verteilerbehälters integriert sind und es ermöglichen, den untersten Rand des anderweitig abgestützten Vorratsbehälters, der seitlich übergreifend über die Schraubenschächte hinausragt, auf dem Flansch 101 des Verteilerbehälters mit Schrauben zu befestigen.The edge of the flange 101 surrounding the cylindrical housing 100 of the header tank is provided with a certain number of screw shafts 150, i. with cylindrical units which are integrated in the structure of the distribution container and make it possible to fasten the lowermost edge of the otherwise supported reservoir, which laterally projects beyond the screw shafts, onto the flange 101 of the distributor container with screws.

Diese verschiedenen Elemente, wie z.B. die sanitären Einlass- und Auslassleitungen 110, 120, die umgebende Wand 100, der Flansch 101 und die Schraubenschächte 150 sind durch querliegende Flächenelemente 160 und dazwischenliegend angeordnete Flächenelemente 161, 162 in Form eines die Anordnung versteifenden Fachwerks miteinander verbunden und erlauben als Ganzes die Formgebung durch Spritzgießen in einer relativ einfachen Form. Die Anzahl der Schraubenschächte sowie das Netz der Flächenelemente und Rippen gewährleisten langfristig die Steifigkeit und die Ebenheit der Oberfläche der Abdichtung zwischen dem Verteilerbehälter und dem Vorratsbehälter.These various elements, such as e.g. the sanitary inlet and outlet conduits 110, 120, the surrounding wall 100, the flange 101 and the screw shafts 150 are interconnected by transverse panels 160 and intermediate panels 161, 162 in the form of a truss stiffening structure and permit molding as a whole Injection molding in a relatively simple form. The number of screw shafts and the network of surface elements and ribs long-term ensure the rigidity and the flatness of the surface of the seal between the header tank and the reservoir.

Die querliegenden Flächenelemente 160, die die Leitungen 110, 120 einfassen, verbinden paarweise die Schraubenschächte 150. Diese doppelt und auseinanderliegend ausgeführten querliegenden Flächenelemente 160 reichen bis unter den Flansch 101. Die dazwischen liegend angeordneten Flächenelemente 161, 162 bilden eine Struktur eines die Anordnung in Querrichtung versteifenden Fachwerks. Zuletzt erstreckt sich ein in Längsrichtung angeordnetes Flächenelement 163 entlang der Längssymmetrieebene des Verteilerbehälters, ohne dabei jedoch in das Innere des die Vorkammer bildenden Hohlraums vorzudringen (Figur 2).The transverse panels 160, which enclose the conduits 110, 120, couple the screw wells 150 in pairs. These double and spaced transverse panels 160 extend below the flange 101. The intermediate panels 161, 162 form a transverse structure stiffening framework. Finally, a longitudinally disposed surface element 163 extends along the longitudinal plane of symmetry of the distribution container, without, however, penetrating into the interior of the cavity forming the prechamber ( FIG. 2 ).

Der Querschnitt in Figur 3A zeigt die beiden Leitungen 110, 120 und ihre Stutzen 130, 140 sowie die umgebende Wand 100 mit dem Flansch 101, der zwei Schraubenschächte 150 umfasst, die jeweils mit einem querliegenden Doppelflächenelement 160 miteinander verbunden sind. Dieser Schnitt zeigt die Öffnung 132 an der Schnittstelle zwischen der Wassereinlassleitung 110 und dem Wassereinlassstutzen 130 sowie die Schnittstelle durch das Stück 133 zwischen den beiden Stutzen 130 und 140.The cross section in FIG. 3A shows the two lines 110, 120 and their sockets 130, 140 and the surrounding wall 100 with the flange 101, which comprises two screw shafts 150, which are each connected to a transverse double surface element 160 with each other. This section shows the opening 132 at the interface between the water inlet ducts 110 and the water inlet port 130 and the interface through the piece 133 between the two ports 130 and 140th

Die Schnittdarstellung in Längsrichtung des Verteilerbehälters gemäß Figur 3B hebt die axiale Position gemäß der ZZ-Achse des Abschnitts des Stutzens 130 zur Aufnahme des Hutes hervor mit den beiden Widerlagern 131 sowie den Wänden 121 der Leitung 120 und dem flachen Bereich 102 des Bodens des Hohlraums, der darüber hinaus durch die umgebende Wand 100 eingefasst ist. Im Bereich des Schnittes trifft die umlaufende Wand 100 mit dem mittleren längsgerichteten Flächenelement 163 und dem Flansch 101 zusammen.The sectional view in the longitudinal direction of the distributor tank according to FIG. 3B highlights the axial position along the ZZ axis of the portion of the neck receiving sleeve 130 with the two abutments 131 and the walls 121 of the conduit 120 and the flat portion 102 of the bottom of the cavity, which is further bordered by the surrounding wall 100 is. In the region of the section, the circumferential wall 100 coincides with the central longitudinal surface element 163 and the flange 101.

Der getrennt von dem Verteilerbehälter über Spritzgießen gefertigte Hut C zum Abdecken des Wassereinlassstutzens 130 wird in einer isometrischen Ansicht in den Figuren 4 und 5 und in einer Darstellung des Schnitts durch die beiden senkrecht zueinander stehenden vertikalen Ebenen in den Figuren 6 und 7 gezeigt.The separately made of the header tank via injection molding C to cover the water inlet nozzle 130 is in an isometric view in the FIGS. 4 and 5 and in a representation of the section through the two mutually perpendicular vertical planes in the FIGS. 6 and 7 shown.

Der Hut C setzt sich zusammen aus einem durchbrochenen Formkörper 200, der dazu bestimmt ist, den Wassereinlassstutzen 130 und die Öffnung 132 an der Verbindungsstelle zwischen Stutzen 130 und Wassereinlassleitung 110 abzudecken und zu überlappen, um den von der Seite her ankommenden Strahl abzulenken, ihn gegen die Achse ZZ des Verteilerbehälters neu zu bestimmen und ihn schließlich gleichmäßig entlang der Seiten in Richtung der umgebenden Wand 100 aufzufächern, bevor das Wasser langsam in den Vorratsbehälter aufsteigt.The hat C is composed of a perforated molding 200 intended to cover and overlap the water inlet port 130 and the opening 132 at the joint between the nozzle 130 and the water inlet pipe 110 to deflect the beam arriving from the side towards it to redetermine the axis ZZ of the header tank and finally fan it evenly along the sides toward the surrounding wall 100 before the water slowly rises into the hopper.

Der unterbrochene Formkörper 200 des Hutes besitzt einen horizontalen Abschnitt in ovaler Form, korrespondierend mit der äußeren Kontur des Wassereinlassstutzens 130. Diese Form ist symmetrisch bezogen auf die quer verlaufende mittlere Ebene und bezogen auf die in Längsrichtung verlaufenden Ebene des Verteilerbehälters. Der Formkörper 200 weist auf einer Seite eine Führungsfläche 210 mit Übergangsdreiecken 220 auf, um den Abstand zwischen dem Wassereinlassstutzen 130 und der Wassereinlassleitung 110 zu überbrücken (die Achse des Stutzens 130The interrupted molded body 200 of the hat has a horizontal portion in an oval shape corresponding to the outer contour of the water inlet stub 130. This shape is symmetrical with respect to the transverse central plane and with respect to the longitudinal plane of the header tank. The molded body 200 has on one side a guide surface 210 with transition triangles 220 to bridge the distance between the water inlet nozzle 130 and the water inlet conduit 110 (the axis of the nozzle 130

und die Achse der Leitung 110 stehen senkrecht zueinander, wobei die eine vertikal und die andere horizontal angeordnet ist) .and the axis of the conduit 110 are perpendicular to each other, one being vertical and the other being horizontally arranged).

Im oberen Bereich ist der Hut geprägt durch eine konische Ablenkungsfläche 230, die auf der ZZ-Achse des Verteilerbehälters zentriert ist, wenn der Hut installiert ist. Diese auf ihrer Oberseite durch radiale Rippen 231 verstärkte Ablenkungsfläche 230 ist mit dem Formkörper 200 des Hutes über zwei vertikale Arme 240 verbunden. Der eine der Arme ist auf der Führungsfläche 210 mit einem Achselstück 241 versehen.In the upper area, the hat is defined by a conical deflection surface 230 centered on the ZZ axis of the hopper when the hat is installed. This deflection surface 230 reinforced on its upper side by radial ribs 231 is connected to the shaped body 200 of the hat via two vertical arms 240. One of the arms is provided on the guide surface 210 with a shoulder piece 241.

Seitlich in Bezug auf die mittlere Ebene, d.h. vorne und hinten gemäß der Orientierung in Längsrichtung des Verteilerbehälters, weist der Formkörper 200 zwei Laschen 201 zum Einclipsen auf, die dazu bestimmt sind, mit den Widerlagern 131 zum Einclipsen im Bereich des Vorbaus des Wassereinlassstutzens 130, wie es in Figur 1 offenbart wird, in Wirkverbindung zu treten. Die Laschen 201 sind so mit der Basis 202 des Formkörpers 200 verbunden, dass die Laschen in entgegengesetzter Richtung gegen die Unterseite der Widerlager 131 zum Einclipsen des Wassereinlassstutzens 130 stoßen, wenn die Basis 202 auf den Boden des Verteilerbehälters trifft.Laterally with respect to the middle plane, ie front and rear according to the orientation in the longitudinal direction of the distribution container, the shaped body 200 has two clip-on tabs 201, which are intended to be clipped to the abutment 131 in the region of the front of the water inlet nozzle 130, as it is in FIG. 1 disclosed to be in operative connection. The tabs 201 are connected to the base 202 of the molded body 200 so that the tabs in the opposite direction abut against the underside of the abutments 131 for clipping in the water inlet port 130 when the base 202 hits the bottom of the header tank.

Der untere umlaufende Rand des Formkörpers 200 des Hutes C besitzt die Komplementärform zur Form der Kontur, die durch den flachen Boden 102 des Verteilerbehälters, die Wand 121 der Wassereinlassleitung 120 und die Verbindung 123 zwischen den beiden Stutzen 130, 140 ausgebildet wird, was zusammen mit den seitlichen Bereichen des Formkörpers 200, die mit der äußeren Oberfläche des Einlassstutzens 130 in Berührung kommen, sicherstellt, dass der Hut geschlossen bleibt, womit jegliche Geräuschquelle vermieden wird, um so mehr, da die Form des ovalen Abschnitts des Stutzens 130 und des Formkörpers 200 des Hutes eine Rotationsblockade bilden.The lower peripheral edge of the molded body 200 of the hat C has the complementary shape to the shape of the contour formed by the flat bottom 102 of the header tank, the wall 121 of the water inlet 120 and the connection 123 between the two stubs 130, 140, which together with the lateral regions of the molded body 200 which come into contact with the outer surface of the inlet nozzle 130 ensures that the hat remains closed, thus avoiding any noise source, more so because the shape of the oval portion of the neck 130 and the molding 200 make a rotation blockade of the hat.

Der einmal auf dem Einlassstutzen 130 installierte Hut C spart somit zwei seitliche Fenster 250 oberhalb des Rands 134 (Figur 3A) des Stutzens 130 aus, durch die der zufließende Wasserstrahl, der am Ausgang der Einlassleitung 110 gegen die Achse ZZ des Hutes abgelenkt wird, gleichmäßig durch die Ablenkungsfläche 230 des Hutes vom Außenbereich zurückgehalten wird und sich gegen das zylindrische Gehäuse 100 des Verteilerbehälters richtet.Once installed on the inlet port 130, the hat C thus saves two lateral windows 250 above the edge 134 (FIG. FIG. 3A ) of the nozzle 130, through which the inflowing water jet, deflected at the exit of the inlet duct 110 against the axis ZZ of the hat is uniformly retained by the deflection surface 230 of the hat from the outside and directed against the cylindrical housing 100 of the header tank.

Auf der der Führungsoberfläche 210 (Figur 5) gegenüberliegenden Seite weist der Formkörper 200 eine Einbuchtung 260 auf, die es ihm ermöglicht, sich zwischen den Stutzen 140, der das Auslassrohr aufnimmt, und die Oberfläche in Richtung Einlassstutzen 130 zu schieben und das Zwischenstück 133 zu überdecken, das durch die starke Annäherung des beiden Stutzen 130, 140 zustande kommt.On the guide surface 210 (FIG. FIG. 5 ) on the opposite side, the molding 200 has a recess 260, which allows it to slide between the nozzle 140, which receives the outlet pipe, and the surface in the direction of the inlet port 130 and to cover the intermediate piece 133, which by the strong approximation of two sockets 130, 140 is achieved.

Die seitliche Schnittdarstellung des Hutes C gemäß Figur 6 hebt die Form des Grundkörpers hervor mit einem praktisch kreisförmigen zylindrischen Abschnitt, der der ZZ-Achse des Verteilerbehälters folgt, und dem seitlichen Bereich des Formkörpers 200, der durch die gerade abfallende Führungsfläche 210 gebildet wird, sowie den beiden Verbindungsdreiecken 220, die auf irgendeine Weise den Bereich des Stutzens 130 außerhalb seines kreisförmigen Abschnitts abdecken. Diese Figur offenbart gleichermaßen die Einbuchtung 260.The lateral sectional view of the hat C according to FIG. 6 highlights the shape of the main body with a substantially circular cylindrical portion following the ZZ axis of the header tank and the lateral area of the molded body 200 formed by the straight falling guide surface 210 as well as the two connecting triangles 220 in some way cover the area of the nozzle 130 outside of its circular section. This figure likewise discloses the indentation 260.

Der Schnitt der Figur 7 zeigt hauptsächlich die Laschen 201 und die Einbuchtung 260.The cut of the FIG. 7 shows mainly the tabs 201 and the indentation 260.

Die Figuren 8A, 8B zeigen den auf dem Stutzen 130 des Verteilerbehälters N installierten Hut C und insbesondere die Ankopplung des Laschen zum Einclipsen 201 unterhalb der seitlichen Widerlagern 131 des Einlassstutzens 130 und das Auftreffen der Basis 202 auf die Bodenplatte 102 des Verteilerbehälters.The Figures 8A, 8B show the hat C installed on the neck 130 of the header tank N and in particular the coupling of the tabs for clipping 201 below the lateral abutments 131 of the inlet sleeve 130 and the impact of the base 202 on the bottom plate 102 of the header tank.

Die Führungsfläche 210 zeigt deutlich, wie sie die Öffnung 132 abdeckt und das Wasser der ZZ-Achse folgend in Richtung des kreisförmigen zylindrischen Bereichs des Stutzens 130 führt, damit der Strahl so in der Achse der konischen Ablenkungsfläche 230 eintritt.The guide surface 210 clearly shows how it covers the opening 132 and guides the water following the ZZ-axis in the direction of the circular cylindrical portion of the nozzle 130, so that the jet enters in the axis of the conical deflection surface 230.

Die Figur 8B zeigt insbesondere die Position der Fenster 250 für den seitlichen Austritt des durch den Hut C abgelenkten Wassers, d.h. die konische Oberfläche auf der Achse des Verteilerbehälters (und des Vorratsbehälters); die Strömung des Wassers wird gegen die zylindrische seitliche Wand 100 der Vorkammer des Verteilerbehälters dirigiert.The FIG. 8B in particular shows the position of the windows 250 for the lateral exit of the water deflected by the hat C, ie the conical surface on the axis of the distributor tank (and of the storage tank); the flow of water is directed against the cylindrical side wall 100 of the prechamber of the header tank.
