Die Erfindung wird an einem Teilschnitt durch die mit einem Rohrheizkörper zu einer Einheit kombinierten Umwälzpumpe näher erläutert.The invention is based on a partial section with a tubular heater a unit combined circulation pump explained in more detail.
Von dem Ablaufschacht 10 des Spülbehälters ist in der Zeichnung nur ein Teilbereich gezeigt, in dem eine Umwälzpumpe für das Spülwasser eingebaut ist. Die Umwälzpumpe saugt das Spülwasser aus einem tieferliegenden, nicht mehr dargestellten Sumpf des Ablaufschachtes 10 an.Only a portion of the drain shaft 10 of the washing container is shown in the drawing, in which a circulation pump for the washing water is installed. The circulating pump draws in the flushing water from a lower sump of the downcomer 10 , which is no longer shown.
In den Ablaufschacht 10 ist ein Rotorgehäuse-Topf 11 eingeformt, der zum Spülbehälter hin, d. h. nach oben, offen ist und im Bodenbereich eine Aufnahme 12 für ein Lager einer Lagerwelle 22 eines Rotors 20 eines Elektromotors bildet. Auf diesen Rotorgehäuse-Topf 11 ist ein mit einer elektronischen Steuerung versehener Stator 21 eines elektronisch kommutierbaren Synchronmotors auf geschoben und unverdrehbar darauf gehalten. Dies kann durch Anbringung ent sprechender Führungs- und Halteelemente erreicht werden. A rotor housing pot 11 is formed in the drain shaft 10 , which is open towards the rinsing container, ie upwards, and forms a receptacle 12 for a bearing of a bearing shaft 22 of a rotor 20 of an electric motor in the bottom region. A stator 21 of an electronically commutatable synchronous motor, which is provided with an electronic control, is pushed onto this rotor housing pot 11 and held thereon in a non-rotatable manner. This can be achieved by attaching appropriate guide and holding elements.
Die Lagerwelle 22, die gleichzeitig Antriebswelle des Elektromotors ist und den Rotor 20 trägt, kann dem Spülbehälter zugekehrt in einem weiteren Lager 23 drehbar gelagert sein. Dieses weitere Lager 23 ist in einem Lagerschild 24 gehalten, der in einem erweiterten Lagerabschnitt 13 des Ablaufschachtes 10 gehalten ist. Die Lagerwelle 22 trägt anschließend an das weitere Lager 23 ein Pumpenlaufrad 27, das von einem Rohrheizkörper 28 umgeben ist, der das Pumpengehäuse des Pumpenaggregates bildet. Der Rohrheizkörper 28 kann ein Stahlrohrabschnitt sein, auf dem ein Heizstab aufgewickelt ist. Er kann auch eine in Quarz eingebettete Heizspirale 29 aufweisen, die zwischen zwei Rohr abschnitten gehalten ist. Dieser Rohrheizkörper 28 hat am unteren Ende isolierte Anschlußstutzen 29a, die in dem Ablaufschacht 10 isoliert gehalten und auf die Unterseite desselben geführt sind, wo sie mit einem Element 30 gehalten und als Stromanschlüsse 29b zugänglich sind. Um den Rohrheizkörper 28 ist ein Feinfilter 25 angebracht, mit dem feine Schmutzteile zurückgehalten werden. Dieses Feinfilter 25 kann im unteren Bereich mit steuerbaren Einlaßöffnungen 26 versehen sein, wenn dies für ausreichende Versorgung der Sprüharme mit Spülwasser erforderlich ist. Dieses Feinfilter 25 kann mit dem Lagerschild 24 einstückig ausgebildet sein und in einem weiteren Lagerabschnitt 14, der sich wie der Lagerabschnitt 13 am oberen Ende des Rotorgehäuse-Topfes 11 anschließt, zusätzlich gehalten sein.The bearing shaft 22 , which is at the same time the drive shaft of the electric motor and carries the rotor 20 , can be rotatably mounted in a further bearing 23 facing the washing container. This further bearing 23 is held in a bearing plate 24 which is held in an expanded bearing section 13 of the downcomer 10 . The bearing shaft 22 then carries to the further bearing 23 a pump impeller 27 which is surrounded by a tubular heating element 28 which forms the pump housing of the pump unit. The tubular heating element 28 can be a steel tube section on which a heating rod is wound. It can also have a heating coil 29 embedded in quartz, which is held between two pipe sections. This tubular heater 28 has at the lower end insulated connecting pieces 29 a, which are kept insulated in the downcomer 10 and guided to the underside of the same, where they are held with an element 30 and are accessible as power connections 29 b. A fine filter 25 is attached to the tubular heating element 28 , with which fine dirt particles are retained. This fine filter 25 can be provided in the lower area with controllable inlet openings 26 if this is necessary for sufficient supply of the spray arms with rinsing water. This fine filter 25 can be formed in one piece with the end shield 24 and can additionally be held in a further bearing section 14 which, like the bearing section 13, adjoins the upper end of the rotor housing pot 11 .
Das den Ablaufschacht 10 überdeckende Sieb 31 weist eine Bohrung 32 auf, in der das Feinfilter 25 zusammen mit dem oberen Ende des Rohrheizkörpers 28 und einem Lagerelement 34 gehalten sind. Das Feinfilter 25 ist bis zum An liegen eines Bundes 33 in die Bohrung 32 des Siebes 31 eingesteckt. Das Lagerelement 34 ist in nicht dargestellter Weise lösbar mit dem Feinfilter 25 und/oder Sieb 31 verbunden und weist dem Rohrheizkörper 28 zugekehrt einen Lageransatz 35 auf, in den das obere Ende des Rohrheizkörpers 28 eingeführt und darin gehalten ist. An diesem Lagerelement 34 sind Abgänge 36 und 37 angeformt. Der Abgang 36 führt zu einem an oder in der Rückwand des Spülbe hälters angebrachten Verbindungskanal zu dem oberen Sprüharm oder zu obe ren Sprühdüsen. Der Abgang 37 ist vertikal gerichtet und dient gleichzeitig als Aufnahme für einen Zuführungskanal 38 zum unteren Sprüharm. Außerdem weist das Lagerelement 34 eine Lagerbuchse 39 auf, in der eine Lagerwelle 40 des unteren Sprüharmes drehbar gelagert ist.The sieve 31 covering the downcomer 10 has a bore 32 in which the fine filter 25 is held together with the upper end of the tubular heating element 28 and a bearing element 34 . The fine filter 25 is inserted into a collar 33 in the bore 32 of the sieve 31 . The bearing element 34 is detachably connected to the fine filter 25 and / or sieve 31 in a manner not shown and has a bearing attachment 35 facing the tubular heating element 28 , into which the upper end of the tubular heating element 28 is inserted and held therein. Outlets 36 and 37 are formed on this bearing element 34 . The outlet 36 leads to a connection channel attached to or in the rear wall of the flushing container to the upper spray arm or to upper spray nozzles. The outlet 37 is directed vertically and at the same time serves as a receptacle for a feed channel 38 to the lower spray arm. In addition, the bearing element 34 has a bearing bush 39 in which a bearing shaft 40 of the lower spray arm is rotatably mounted.
Wie dem Schnitt zu entnehmen ist, strömt das von der Umwälzpumpe ange saugte Spülwasser an der Außen- und Innenseite des Rohrheizkörpers 28 entlang, so daß die Heizwirkung wesentlich verbessert ist. Die Heizleistung des Rohrheizkörpers 28 kann daher auch reduziert werden, was zu einer Kostensen kung im Betrieb ausgenützt werden kann.As can be seen from the section, the flushing water drawn in by the circulating pump flows along the outside and inside of the tubular heating element 28 , so that the heating effect is substantially improved. The heating power of the tubular heater 28 can therefore also be reduced, which can be used to reduce costs in operation.
Das obere Ende des Rohrheizkörpers 28 kann auch wie das Feinfilter 25 zu sammen mit dem Lagerelement 34 in der Bohrung 32 des Siebes 31 gehalten werden.The upper end of the tubular heater 28 can also be held together with the bearing element 34 in the bore 32 of the sieve 31 like the fine filter 25 .
