Abstract
Description
Die vorliegende Erfindung betrifft ein Trinkwasserfilter, insbesondere rückspülbares und/oder ausspülbares Trinkwasserfilter und/oder Trinkwasserfilterkombination, mit einem Filtereinsatz, der einen ersten Stützkörper und eine Filterkörper umfasst, wobei der Stützkörper ein rohrförmiger Hohlkörper ist, der wenigstens eine Wand hat, die ein Vielzahl von Durchgangslöchern aufweist, und wobei der Filterkörper außenseitig auf oder an dem ersten Stützkörper angebracht ist.The present invention relates to a drinking water filter, in particular backwashable and / or flushable drinking water filter and / or drinking water filter combination, comprising a filter insert comprising a first support body and a filter body, wherein the support body is a tubular hollow body having at least one wall having a plurality of Having through holes, and wherein the filter body is mounted on the outside or on the first support body.
Aus den Dokumenten
Der den ersten Stützkörper bildende rohrförmiger Hohlkörper, kann auf verschiedene Art und Weise ausgebildet sein. Es kann sich dabei zum Beispiel um ein Kunststoffspritzgussteil handeln, dass ggf. mit Fasern verstärkt ist. Ebenso kann es sich um ein Edelstahlblech handeln, welches gebogen und durch Stanzen mit den Durchgangslöchern versehen ist. Außerdem ist es möglich, dass der erste Stützkörper koaxial und mit Abstand zueinander angeordnete Ringe aufweist, die an Stangen befestigt sind, die parallel zur Mittelachse der Ringe mit den Innenseiten der Ringe verbunden sind.The tubular body forming the first support body may be formed in various ways. This may be, for example, a plastic injection-molded part that is possibly reinforced with fibers. Likewise, it may be a stainless steel sheet, which is bent and provided by punching with the through holes. In addition, it is possible for the first support body to have coaxial and spaced-apart rings fixed to rods which are connected to the inner sides of the rings parallel to the central axis of the rings.
Die Durchgangslöcher des ersten Stützkörpers sind von dem Filterkörper abgedeckt. Dabei kann es sich um ein Vlies, Gewebe, Gewirk, Gestrick oder ähnliches Handeln. Der Filterkörper kann aus jedem zur Filterung von Trinkwasser geeignetem Material bestehen. Der Filterköper ist in der Regel an dem ersten Stützköper fixiert. Die Filtereinsätze werden im Normalbetrieb von außen nach innen durchströmt.The through holes of the first support body are covered by the filter body. It can be a fleece, fabric, knitted fabric or similar action. The filter body can consist of any material suitable for filtering drinking water. The filter body is usually fixed to the first support body. The filter cartridges are flowed through in normal operation from outside to inside.
Filtereinsätze von Trinkwasserfiltern müssen eine Prüfung nach
Bei der Gestaltung der ersten Stützkörper wurde in Vergangenheit immer wieder versucht, den Materialeinsatz für den Stützköper zu minimieren, die Durchströmbarkeit des ersten Stützkörpers zu maximieren und den ersten Stützköper und die Verbindung des Filterkörpers und des ersten Stützkörpers möglichst belastbar zu gestalten. Diese zum Teil widersprechenden Anforderungen in dem erste Stützköper zu realisieren ist schwierig.In the design of the first support body has been tried again and again in the past to minimize the use of material for the support body, to maximize the Durchströmbarkeit the first support body and to make the first support body and the connection of the filter body and the first support body as strong as possible. To realize these partly contradictory requirements in the first supporting body is difficult.
Der Erfindung lag daher die Aufgabe zu Grunde, ein Trinkwasserfilter der eingangs genannten Art so zu verbessern, dass der Filtereinsatz einerseits möglichst einfach gestaltet ist und andererseits möglichst haltbar und normgerecht gestaltet ist.The invention was therefore based on the object to improve a drinking water filter of the type mentioned so that the filter element on the one hand is designed as simple as possible and on the other hand designed as durable and standard.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass das Trinkwasserfilter einen zweiten Stützkörper aufweist, der innerhalb des ersten Stützkörpers angeordnet ist und innenseitig an dem ersten Stützkörper anliegt oder zumindest im Betrieb des Trinkwasserfilters anliegt.This object is achieved in that the drinking water filter has a second support body which is disposed within the first support body and on the inside bears against the first support body or at least rests during operation of the drinking water filter.
Dadurch dass ein zweiter Stützkörper vorgesehen ist, ist es möglich einen einfach herstellbaren Filterseinsatz zu schaffen, der den geschilderten Anforderungen entspricht. Die Gestaltung der beiden Stützkörper kann auf unterschiedliche Anforderungen ausgerichtet sein.By providing a second support body, it is possible to provide a filter insert which is easy to produce and which corresponds to the described requirements. The design of the two support body can be aligned to different requirements.
So kann man bei der Gestaltung des ersten Stützkörpers zum Beispiel den Blick darauf richten, dass dieser möglichst gut durchströmbar ist und den Filterkörper in Position hält. Bei der Gestaltung des zweiten Stützkörpers kann man dagegen den Blick auf die Druckfestigkeit des Filtereinsatzes richten.For example, in the design of the first support body, one can direct the view that it can be flowed through as well as possible and keeps the filter body in position. In the design of the second support body, however, one can direct the view of the compressive strength of the filter cartridge.
Durch die Verteilung der Funktionen auf den ersten und den zweiten Stützköper, kann für jeden Stützkörper ein geeignetes Material verwendet werden, dass sich vom Material des anderen Stützkörpers unterscheiden kann.Due to the distribution of the functions on the first and the second support body, a suitable material can be used for each support body, which may differ from the material of the other support body.
Der zweite Stützkörper kann ein Wendel sein. Dieser Wendel kann an der Innenseite des ersten Stützkörpers anliegen und die von außen nach innen wirkenden Kräfte aufnehmen.The second support body may be a helix. This coil can rest on the inside of the first support body and absorb the forces acting from outside to inside.
Vorteilhaft kann der zweite Stützkörper eine Schraubenfeder sein. Schraubenfedern, auch solche aus Edelstahl können in großer Stückrahl zu günstigen Preisen hergestellt werden. Zum Teil handelt es sich um genormte Serienprodukte, die von verschiedenen Herstellern auf dem Markt angeboten werden und deshalb kostengünstig bezogen werden können. Schraubenfedern sind daher besonders als zweite Stützkörper geeignet, wobei es bei diesen Federn beim Einsatz im Trinkwasserfilter nicht auf die Federeigenschaften in einer Axialrichtung der Feder ankommt.Advantageously, the second support body may be a helical spring. Coil springs, even those made of stainless steel can be produced in large pieces at reasonable prices. Some of them are standardized series products that are offered by various manufacturers on the market and can therefore be obtained inexpensively. Coil springs are therefore particularly suitable as a second support body, wherein it does not depend on the spring properties in an axial direction of the spring in these springs when used in the drinking water filter.
Der zweite Stützkörper kann aus Edelstahl und/oder Kunststoff bestehen.The second support body may be made of stainless steel and / or plastic.
Der zweite Stützkörper kann im ersten Stützkörper integriert sein und die Stützkörper können ein Teil bilden. Die den zweiten Stützkörper bildende Feder kann mit Kunststoff des ersten Stützkörpers umspritzt sein.The second support body may be integrated in the first support body and the support body may form a part. The second support body forming spring may be encapsulated with plastic of the first support body.
