Abstract

The invention relates to a W.C. bowl (1) in which the water supply tube (2) and the discharge tube (3) run from the wall in a direction toward the W.C. bowl (1) in an inclined manner. As a result, a higher seating surface is obtained despite uniform connection heights for the tube lines. An emptying channel (5) is provided to prevent water from remaining in the water supply tube (2). Said emptying channel leads away from the water supply tube (2) and opens into the stench trap (4) at a position which is situated under the water level (6) and which cannot be seen from the exterior.

Description

WC-Schale Toilet bowl
Technisches GebietTechnical field
Die vorliegende Erfindung betrifft eine WC-Schale mit einem Wasserzulaufröhr, einem Auslaufrohr und einem Geruchs- verschluss .The present invention relates to a toilet bowl with a water inlet pipe, an outlet pipe and an odor trap.
Stand der TechnikState of the art
Derartige WC—Schalen finden sich in jedem Haushalt. Ihre Höhe ist so bemessen, dass die WC-Schalen nicht nur von Er- wachsenen, sondern auch von Kindern benutzt werden können.Such toilet bowls can be found in every household. Their height is such that the toilet bowls can be used not only by adults, but also by children.
Ihre Höhe ist somit ein Kompromiss; sie sind für kleine Kinder zu hoch und für Erwachsene zu niedrig.Their height is therefore a compromise; they are too high for small children and too low for adults.
Für ältere Personen kann die zu geringe Höhe beim Hin- setzen, insbesondere aber beim Aufstehen beschwerlich sein. Für ältere Personen wäre es daher zweckmässig, die WC-Schale etwas höher anzuordnen.For older people, the low height when sitting down, but especially when standing up, can be difficult. It would therefore be advisable for older people to arrange the toilet bowl a little higher.
Wegen den in der Montagewand verlegten Zu- und Abfluss- röhren kann man aber eine WC-Schale nicht einfach höher montieren. Man muss bei herkömmlichen WC-Schalen viel mehr die Anschlussrohre verlegen, was mit zusätzlichen Stemmarbeiten verbunden ist. Da WC-Räume zumeist verfliest sind, bedeutet dies, dass nach einem solchen Umbau auch eine Neuverfliesung notwendig ist. Besonders ältere Menschen scheuen einen derartigen Aufwand, so dass sie lieber die etwas zu geringe Sitzhöhe in Kauf nehmen. Abriss der ErfindungHowever, because of the inlet and outlet pipes installed in the mounting wall, you cannot simply mount a toilet bowl higher. With conventional toilet bowls, the connection pipes have to be laid much more, which is associated with additional chiseling work. Since toilet rooms are mostly tiled, this means that after such a conversion, new tiling is also necessary. Older people in particular shy away from such an effort, so they prefer to accept the somewhat low seat height. Outline of the invention
Es ist Aufgabe der vorliegenden Erfindung, eine WC-Schale zu schaffen, die eine höhere Sitzflache aufweist und dennoch an die bestehenden, normgemass verlegten Zu- und Ablaufrohre angeschlossen werden kann, so dass beim Einbau keinerlei Stemmarbeiten notwendig sind.It is an object of the present invention to provide a toilet bowl which has a higher seating area and can nevertheless be connected to the existing inlet and outlet pipes laid according to standards, so that no chiseling work is necessary during installation.
Die erfmdungsgemasse WC-Schale ist dadurch gekennzeich- net, dass das Wasserzulaufröhr ansteigend ist und dass ein Entleerungskanal für das Wasserzulaufröhr vorgesehen ist.The toilet bowl according to the invention is characterized in that the water inlet pipe rises and that an emptying channel is provided for the water inlet pipe.
Auch bei erhöhter Sitzflache soll das Spulwasser knapp unter dem oberen Rand der WC-Schale bis nach vorne fliessen. Damit dies möglich ist, verlauft das Wasserzulaufröhr innerhalb der Schale in Stromungsrichtung ansteigend.Even when the seat is elevated, the rinsing water should flow to the front just below the upper edge of the toilet bowl. To make this possible, the water inlet pipe inside the bowl rises in the direction of flow.
Wie sich im Rahmen der vorliegenden Erfindung herausgestellt hat, wird mit solch einem ansteigenden Wasser- zulaufröhr aber keine zufriedenstellende Spulwirkung erzielt. Nach erfolgter Spulung bleibt nämlich Wasser im Wasserzulaufrohr stehen. Bei der nachfolgenden Spulung trifft daher das vom Spulkasten (der beispielsweise m der Wand eingemauert ist) herabstürzende Wasser zunächst auf das im Wasserzu- laufrohr stehende Wasser, so dass seine kinetische Energie weitestgehend vernichtet wird. Aus diesem Grunde ist erfm- dungsgemass ein Entleerungskanal für das Wasserzulaufröhr vorgesehen. Dieser Entleerungskanal geht zweckmassigerweise vom tiefsten Punkt des Wasserzulaufrohres weg und mundet irgendwo an einer tiefer gelegenen Stelle in die WC-Schale. Dieser Entleerungskanal kann einen relativ kleinen Querschnitt aufweisen. Dies ist sogar gunstig, damit nur wenig Wasser wahrend des Spulvorganges durch den Entleerungskanal verlorengeht. Nach dem Spulvorgang ist aber Zeit genug, dass das im Wasserzulaufröhr stehengebliebene Wasser langsam durch den Entleerungskanal in die WC-Schale abfliesst, so dass zu Beginn des nächsten Spülvorganges das Wasserauslaufröhr frei von Restwasser ist.As has been found in the context of the present invention, however, a satisfactory rinsing effect is not achieved with such a rising water inlet pipe. After rinsing, water remains in the water supply pipe. In the subsequent winding, the water falling from the flush box (which is walled in, for example, the wall) first hits the water in the water inlet pipe, so that its kinetic energy is largely destroyed. For this reason, an emptying channel for the water inlet pipe is provided according to the invention. This drainage channel expediently goes away from the lowest point of the water inlet pipe and flows into the toilet bowl somewhere at a lower point. This emptying channel can have a relatively small cross section. This is even favorable so that only a little water is lost through the drainage channel during the winding process. After the rinsing process, however, there is enough time for the water that has remained in the water inlet pipe to slowly pass through the drainage channel flows into the toilet bowl so that at the beginning of the next flushing process the water outlet pipe is free of residual water.
Bei der erfindungsgemässen WC-Schale wird daher trotz gleicher Wandinstallation eine höhere Sitzfläche geschaffen, und die Spülung erfolgt wie bei herkömmlichen WC—Schalen bis zum oberen Rand.In the case of the toilet bowl according to the invention, therefore, despite the same wall installation, a higher seating area is created, and the flushing takes place up to the upper edge as in conventional toilet bowls.
Es ist zweckmässig, wenn der Entleerungskanal an einer von aussen nicht sichtbaren Stelle endet. Durch das langsame, unter Umstände tropfenweise Austreten von Wasser aus dem Entleerungskanal kann es nämlich zu Kalkablagerung oder auch zu Verfärbungen der WC—Schale kommen.It is expedient if the emptying channel ends at a point that is not visible from the outside. The slow, dropwise drop of water from the emptying channel can lead to limescale deposits or discolouration of the toilet bowl.
Ferner ist es günstig, wenn der Entleerungskanal unter dem Wasserspiegel des Geruchsverschlusses endet. Auf diese Weise kann man nicht hören, wie das Wasser durch den Entleerungskanal abfliesst. Anderenfalls ist möglicherweise ein Plätschern oder Tropfen hörbar.It is also advantageous if the emptying channel ends below the water level of the odor trap. In this way you can not hear how the water flows through the drainage channel. Otherwise, a splash or drip may be heard.
Schliesslich ist es zweckmässig, wenn der Entleerungskanal in Richtung des abfliessenden Wassers in den Geruchs- verschluss mündet. Während des Spülvorganges fliesst bereits Wasser durch den Entleerungskanal ab, weil ja während derFinally, it is expedient if the emptying channel opens into the odor trap in the direction of the draining water. During the rinsing process, water is already flowing out through the drainage channel, because yes during the
Spülung das Wasserzulaufröhr unter Wasser steht. Wenn dieses Wasser in Richtung des abfliessenden Wassers in den Geruchs- verschluss mündet, so gibt es zu Beginn des Spülvorganges dem Wasser im Auslaufröhr einen entsprechenden Impuls. Das Wasser steigt dann weniger hoch an, bevor es durch den Sog im Fallrohr rasch abfliesst. Kurze Beschreibung der ZeichnungRinsing the water supply pipe is under water. If this water flows into the odor trap in the direction of the draining water, the water in the outlet pipe gives a corresponding impulse at the beginning of the rinsing process. The water then rises less before it drains away quickly through the suction in the downpipe. Brief description of the drawing
Anhand der beiliegenden Zeichnung w rd die Erfindung naher erläutert. In dieser zeigtThe invention is explained in more detail with reference to the accompanying drawing. In this shows
die Figur 1 einen Schnitt durch eine erfindungsgemasse WC-Schale mit einem in den Geruchsverschluss mundenden Entleerungskanal und die Figur 2 eine alternative Losung zur Fuhrung des erfmdungsgemassen Entleerungskanals in vergrossertem Massstab.1 shows a section through a toilet bowl according to the invention with an emptying channel emptying into the odor trap; and FIG. 2 shows an alternative solution for guiding the emptying channel according to the invention on an enlarged scale.
Beschreibung eines bevorzugten AusfuhrungsbeispielsDescription of a preferred exemplary embodiment
Die WC-Schale 1 weist - wie ede andere WC-Schale auch - ein Wasserzulaufröhr 2 und ein Auslaufrohr 3 auf. Im Gegensatz zu herkömmlichen WC—Schalen liegen das Wasserzulaufröhr 2 und das Auslaufrohr 3 aber nicht waagrecht, sondern von der Wand m Richtung zur WC-Schale 1 ansteigend. Beim Auslaufrohr 3 ist dies stromungstechnisch gunstig, weil das in Richtung zur Wand abfliessende Wasser auf diese Weise ein Gefalle bekommt. Beim Wasserzulaufröhr 2 muss das Spulwasser, das von der Wand in Richtung zur WC-Schale 1 strömt, eine Steigung überwinden. Dazu ist die Energie ausreichend, sofern das Was- ser nicht zusätzlich gebremst wird. Erfmdungsgemass ist ein Entleerungskanal 5 für das Wasserzulaufröhr 2 vorgesehen. Er beginnt am tiefsten Punkt des Wasserzulaufrohres 2 und leitet alles Wasser, das nach einem Spulvorgang im Wasserzulaufröhr 2 stehenbleibt, ab. Auf diese Weise wird das beim nächsten Spulvorgang vom Spulkasten herabstürzende Wasser nicht durch Restwasser im Wasserzulaufröhr 2 gebremst, so dass es bis knapp unter dem oberen Rand der WC-Schale 1 um die ganze WC- Schale, d.h. zweiseitig bis nach vorne strömen kann. Die Reinigung ist somit bei der erfmdungsgemassen WC-Schale 1 genauso gut wie bei herkömmlichen WC-Schalen, obwohl die Sitzfläche höher ist und das Spülwasser diesen Höhenunterschied überwinden uss.Like any other toilet bowl, the toilet bowl 1 has a water inlet pipe 2 and an outlet pipe 3. In contrast to conventional toilet bowls, however, the water inlet pipe 2 and the outlet pipe 3 are not horizontal, but instead rise from the wall in the direction of the toilet bowl 1. In the case of the outlet pipe 3, this is favorable in terms of flow technology because the water flowing off in the direction of the wall gets a favor in this way. In the water inlet pipe 2, the rinsing water flowing from the wall towards the toilet bowl 1 must overcome an incline. The energy is sufficient for this, unless the water is additionally braked. According to the invention, an emptying channel 5 is provided for the water inlet pipe 2. It begins at the lowest point of the water supply pipe 2 and drains off all water that remains in the water supply pipe 2 after a winding process. In this way, the water falling from the flushing box during the next rinsing process is not slowed down by residual water in the water supply pipe 2, so that it can flow around the entire toilet bowl 1, ie on both sides, to just below the upper edge of the toilet bowl 1. The cleaning of the toilet bowl 1 according to the invention is therefore just as good as that of conventional toilet bowls, although the Seat is higher and the rinse water must overcome this difference in height.
Die WC-Schale 1 weist einen Geruchsverschluss 4 auf, in den von oben eine Trennwand 8 ragt, und der stets mit Wasser gefüllt ist. Der Entleerungskanal 5 führt durch diese Trennwand 8 bis zu deren untersten Stelle. Der Entleerungskanal 5 mündet daher an einer von aussen nicht sichtbaren Stelle unter dem Wasserspiegel 6 in den Geruchsverschluss 4. Auf diese Weise kann das durch den Entleerungskanal 5 abflies- sende Wasser nicht gehört werden, und es ist der Bereich der Öffnung, an welchem sich unter Umständen Kalkablagerungen oder Verfärbungen bilden könnten von aussen nicht sichtbar.The toilet bowl 1 has an odor trap 4, into which a partition 8 projects from above and which is always filled with water. The emptying channel 5 leads through this partition 8 to its lowest point. The emptying channel 5 therefore opens into the odor trap 4 at a location that is not visible from the outside under the water level 6. In this way, the water flowing out through the emptying channel 5 cannot be heard, and it is the area of the opening at which is located Limescale or discolouration may not be visible from the outside.
Ein besonderer Effekt ergibt sich, wenn die Mündung des Entleerungskanals 5 nicht - wie in der Figur 1 dargestellt - nach unten, sondern zum Auslaufrohr 3 hin gerichtet ist, nämlich so wie das in der Figur 2 gezeichnet ist. In diesem Fall wird dem Wasser im Geruchsverschluss 4 bereits zu Beginn des Spülvorganges ein Impuls in Richtung zum Abflussrohr 3 gegeben. (Bereits zu Beginn des Spülvorganges fliesst nämlich Wasser aus dem Wasserzulaufröhr 2 über den Entleerungskanal 5 in den Geruchsverschluss 4. ) Auf diese Weise beginnt das Wasser früher abzufHessen, so dass es zu Beginn des Spülvorgan- ges weniger hoch in der WC-Schale 1 ansteigt.A special effect results if the mouth of the emptying channel 5 is not directed downward, as shown in FIG. 1, but towards the outlet pipe 3, namely as shown in FIG. In this case, the water in the odor trap 4 is given a pulse in the direction of the drain pipe 3 already at the start of the rinsing process. (This is because water flows from the water supply pipe 2 via the drainage channel 5 into the odor trap 4 already at the beginning of the rinsing process.) In this way, the water begins to measure earlier, so that it rises less high in the toilet bowl 1 at the start of the rinsing process .
Die erfindungsgemässe WC-Schale mit erhöhter Sitzfläche lässt sich also ohne Stemmarbeiten anstelle einer herkömmlichen WC-Schale montieren. Das Wasserzulaufröhr 2 und das Auslaufrohr 3 enden vor der Wand in der üblichen genormtenThe toilet bowl according to the invention with a raised seating area can therefore be installed instead of a conventional toilet bowl without any chiseling work. The water inlet pipe 2 and the outlet pipe 3 end in front of the wall in the usual standardized
Höhe. Auch die Öffnungen 7 für die nicht gezeichneten Steinschrauben befindet sich in der üblichen Höhe, so dass nicht einmal neue Löcher für die Schrauben in die Wand gebohrt werden müssen. Height. The openings 7 for the stone screws, not shown, are at the usual height, so that not even new holes for the screws have to be drilled in the wall.
