Description

Die Erfindung betrifft einen Spülkasten für eine Toilette, insbesondere einen heizbaren Spülkasten für eine intelligente Toilette.The invention relates to a cistern for a toilet, in particular a heatable cistern for an intelligent toilet.

Eine moderne intelligente Toilette verfügt über vielfältige Funktionen. Sie ist üblicherweise mit einer Funktion zur Reinigung eines menschlichen Körpers ausgestattet. Um den Komfort einer intelligenten Toilette zu verbessern, wird eine Erwärmungsfunktion in einen an die intelligente Toilette angepassten Spülkasten integriert, so dass der Spülkasten warmes Wasser für eine intelligente Reinigungsanordnung zur Verfügung stellen kann.A modern intelligent toilet has a wide range of functions. It is usually provided with a function for cleaning a human body. In order to improve the comfort of an intelligent toilet, a heating function is integrated into a cistern adapted to the intelligent toilet, so that the cistern can provide warm water for an intelligent cleaning arrangement.

In dem europäischen Bereich muss wegen des strengen Schutzes des trinkbaren Wassers ein hygienisches Gerät mit einer Einrichtung versehen sein, die das Leitungswasser vor einer durch Rückfluss bedingten Verschmutzung schützt und den EN1717 Standard erfüllt. Deswegen muss im europäischen Bereich in dem Spülkasten einer intelligenten Toilette eine Einrichtung zur Verhinderung des Rückflusses angeordnet sein, welche üblicherweise mit einem Luftspalt funktioniert, d. h. das Leitungswasser wird zunächst in einen offenen Freiraum geleitet und steht dann über eine Pumpe als Spülwasser der intelligenten Toilette zur Verfügung. Um den inneren Platz der intelligenten Toilette zu sparen, wird dabei häufig in dem Spülkasten ein Heizungsrohr angeordnet, welches in Erfüllung des EN1717 Standards für das für die Reinigung benötigte warme Wasser sorgt. Allerdings ist bei einer solchen Einrichtung zur Verhinderung des Rückflusses die Temperatur des abgeführten Wassers sehr instabil, insbesondere während der Wasserzuführung, bei der das kalte Wasser in einer großen Menge beigemischt wird. Dies führt zu einer schnell schwankenden Temperatur des abgeführten Wassers und beeinträchtigt den Komfort bei der Benutzung.In the European area, because of the strict protection of potable water, a hygienic device must be equipped with a device that protects the tap water from pollution caused by backflow and meets the EN1717 standard. Therefore, in the European area, a device for preventing the backflow must be arranged in the cistern of an intelligent toilet, which usually works with an air gap, ie Tap water is first led into an open space and is then available as flushing water for the intelligent toilet via a pump. In order to save the inner space of the intelligent toilet, a heating pipe is often arranged in the cistern, which, in compliance with the EN1717 standard, provides the warm water required for cleaning. However, in such a device for preventing the reflux, the temperature of the discharged water is very unstable, especially during the water supply in which the cold water is mixed in a large amount. This leads to a rapidly fluctuating temperature of the discharged water and impairs the comfort during use.

Die Erfindung stellt einen heizbaren Spülkasten für eine intelligente Toilette bereit, der den Rückfluss des Wassers in die Wasserzuführung wirksam verhindert. Erfindungsgemäß ist die technische Lösung wie folgt:
Ein heizbarer Spülkasten für eine intelligente Toilette umfasst einen Körper, an dem ein Wassereinlass und ein Wasserauslass vorgesehen sind, und eine Heizung, wobei in dem Körper eine Trennwand angeordnet ist, die den Innenraum des Körpers in eine obere Wasserkammer und eine untere Wasserkammer unterteilt, wobei die obere Wasserkammer und die untere Wasserkammer miteinander verbunden sind, wobei die Heizung in der unteren Wasserkammer angeordnet ist, wobei sich der Wassereinlass in einem oberen Teil des Körpers befindet und mit der oberen Wasserkammer verbunden ist, und wobei sich der Wasserauslass in der unteren Wasserkammer befindet und mit der unteren Wasserkammer verbunden ist. In der oberen Wasserkammer ist eine Überströmöffnung vorgesehen, deren Höhe niedriger als die Höhe des Wassereinlasses ist.The invention provides a heatable cistern for an intelligent toilet which effectively prevents the water from flowing back into the water supply. According to the invention, the technical solution is as follows:
A heatable cistern for a smart toilet comprises a body on which a water inlet and a water outlet are provided, and a heater, wherein a partition is arranged in the body, which divides the inner space of the body into an upper water chamber and a lower water chamber the upper water chamber and the lower water chamber are connected to each other, the heater is arranged in the lower water chamber, the water inlet is located in an upper part of the body and connected to the upper water chamber, and the water outlet is located in the lower water chamber and connected to the lower water chamber. An overflow opening is provided in the upper water chamber, the height of which is lower than the height of the water inlet.

Im Vergleich mit dem Stand der Technik weist die vorliegende technische Lösung die folgenden Vorteile auf:

  1. 1. Da die Trennwand den Innenraum des Körpers in die obere Wasserkammer und die untere Wasserkammer unterteilt, wird der Druck des aus einer Wasserleitung in die obere Wasserkammer eingeführten Druckwassers entspannt. Das Wasser in der oberen Wasserkammer kann nicht zu der Wasserleitung zurückfließen, auch wenn bei der Wasserleitung eine Leckage auftritt oder ungewollt ein Unterdruck entsteht.
  2. 2. Da die Heizung in der unteren Wasserkammer angeordnet ist, kann die Trennwand den Einfluss des kalten Wassers in der oberen Wasserkammer auf das warme Wasser in der unteren Wasserkammer wirksam verringern, um die Temperatur des Wassers in der unteren Wasserkammer zu stabilisieren und die Stabilität der Temperatur des abgeführten Wassers zu gewährleisten. Aufgrund der Bewegung des warmen Wassers nach oben, kann die Trennwand außerdem die Diffusion des warmen Wassers nach oben wirksam verhindern, so dass das warme Wasser in der unteren Wasserkammer konzentriert ist. Dadurch werden eine höhere Heizungseffizienz sowie ein besserer Effekt der Abführung des warmen Wassers erzielt.
  3. 3. Da die Höhe der Überströmöffnung niedriger als die Höhe des Wassereinlasses ist, stellt die Überströmöffnung sicher, dass das Niveau des Wassers den Wassereinlass nicht überschreitet, was folglich einen Rückfluss verhindert.
In comparison with the state of the art, the present technical solution has the following advantages:
  1. 1. Since the partition divides the inner space of the body into the upper water chamber and the lower water chamber, the pressure of the pressurized water introduced into the upper water chamber from a water pipe is released. The water in the upper water chamber cannot flow back to the water pipe, even if there is a leak in the water pipe or an unintentional negative pressure is created.
  2. 2. Since the heater is arranged in the lower water chamber, the partition wall can effectively reduce the influence of the cold water in the upper water chamber on the warm water in the lower water chamber to stabilize the temperature of the water in the lower water chamber and the stability of the To ensure the temperature of the discharged water. Also, due to the upward movement of the warm water, the partition wall can effectively prevent the warm water from diffusing upward, so that the warm water is concentrated in the lower water chamber. This results in a higher heating efficiency and a better effect of the removal of the warm water.
  3. 3. Since the height of the overflow opening is lower than the height of the water inlet, the overflow opening ensures that the level of the water does not exceed the water inlet, which consequently prevents backflow.

Es ist aus Fig. 1 bis Fig. 6 ersichtlich, dass ein heizbarer Spülkasten für eine intelligente Toilette einen Körper 10 und eine Heizung 20 umfasst. Eine Wasserleitung führt das Wasser in den Körper 10. Die Heizung 20 ist zur Erwärmung des Wassers in dem Körper 10 vorgesehen. Das erwärmte Wasser wird abgeführt, um einer intelligenten Reinigungsanordnung zur Verfügung zu stehen. An dem Körper 10 sind ein Wassereinlass 11 und ein Wasserauslass 12 vorgesehen. In dem Körper 10 ist eine Trennwand 13 angeordnet, die den Innenraum des Körpers in eine obere Wasserkammer 14 und eine untere Wasserkammer 15 unterteilt, wobei die Heizung 20 in der unteren Wasserkammer 15 angeordnet ist. Die obere Wasserkammer 14 und die untere Wasserkammer 15 sind miteinander verbunden. Der Wassereinlass 11 befindet sich in dem oberen Teil des Körpers und ist mit der oberen Wasserkammer 14 verbunden. In der oberen Wasserkammer 14 ist eine Überströmöffnung 16 vorgesehen, wobei die Höhe der Überströmöffnung 16 niedriger ist als die Höhe des Wassereinlasses 11. Der Wasserauslass 12 befindet sich in dem unteren Teil des Körpers und ist mit der unteren Wasserkammer 15 verbunden.It's over FIGS. 1 to 6 It can be seen that a heatable cistern for a smart toilet comprises a body 10 and a heater 20. A water pipe leads the water into the body 10. The heater 20 is provided for heating the water in the body 10. The heated water is drained away to be available for an intelligent cleaning arrangement. A water inlet 11 and a water outlet 12 are provided on the body 10. In the body 10, a partition wall 13 is arranged, which divides the interior of the body into an upper water chamber 14 and a lower water chamber 15, the heater 20 in the lower water chamber 15 is arranged. The upper water chamber 14 and the lower water chamber 15 are connected to each other. The water inlet 11 is located in the upper part of the body and is connected to the upper water chamber 14. An overflow opening 16 is provided in the upper water chamber 14, the height of the overflow opening 16 being lower than the height of the water inlet 11. The water outlet 12 is located in the lower part of the body and is connected to the lower water chamber 15.

Das Wasser aus einer Wasserleitung wird in die obere Wasserkammer 14 eingeführt und dabei entspannt, bevor es von der oberen Wasserkammer 14 in die untere Wasserkammer 15 zur Erwärmung fließt. Dadurch wird im Wasser in dem Körper 10 kein Druck aufgebaut, was einen Rückfluss des Wassers aus dem Spülkasten in die Wasserleitung wirksam verhindert.The water from a water pipe is introduced into the upper water chamber 14 and thereby relaxed before it flows from the upper water chamber 14 into the lower water chamber 15 for heating. As a result, no pressure is built up in the water in the body 10, which effectively prevents the water from flowing back from the cistern into the water pipe.

Zwischen dem Rand der Trennwand 13 und der Innenwand des Körpers 10 ist eine Wasserdurchführung ausgebildet, die die obere Wasserkammer 14 mit der unteren Wasserkammer 15 verbindet, so dass das Wasser in der oberen Wasserkammer in die untere Wasserkammer fließen kann, ohne einen großflächigen Wärmeaustausch zwischen dem warmen Wasser in der unteren Wasserkammer und dem kalten Wasser in der oberen Wasserkammer zu bewirken. Die Wasserdurchführung kann auch direkt in der Trennwand 13 vorgesehen sein.Between the edge of the partition wall 13 and the inner wall of the body 10, a water duct is formed which connects the upper water chamber 14 with the lower water chamber 15 so that the water in the upper water chamber can flow into the lower water chamber without a large-scale heat exchange between the to effect warm water in the lower water chamber and the cold water in the upper water chamber. The water duct can also be provided directly in the partition 13.

Weiterhin ist eine Entgasungsleitung 30 vorgesehen. Das eine Ende der Entgasungsleitung 30 ist in die untere Wasserkammer 15 geführt und befindet sich in einem oberen Teil der unteren Wasserkammer. Das andere Ende erstreckt sich bis aus dem Körper 10 heraus. Dadurch, dass die Entgasungsleitung in der unteren Wasserkammer vorgesehen ist, kann während der Erwärmung des Wassers in der unteren Wasserkammer entstehendes Gas wirksam abgeführt werden. Zusammen mit der Absperrung der Trennwand kann außerdem eine Druckerhöhung im Körper vermieden werden. An der Trennwand 13 ist ein Entgasungsrohr 40 vorgesehen. Das Entgasungsrohr 40 bildet an einem Ende eine Öffnung an der unteren Seite der Trennwand und erstreckt sich nach oben bis aus dem Körper 10 heraus. Der Innenraum des Entgasungsrohrs 40 bildet die Entgasungsleitung 30. Das Entgasungsrohr 40 kann das warme Gas im oberen Teil der unteren Wasserkammer 15 rasch abführen.A degassing line 30 is also provided. One end of the degassing line 30 is led into the lower water chamber 15 and is located in an upper part of the lower water chamber. The other end extends out of the body 10. The fact that the degassing line is provided in the lower water chamber means that gas produced in the lower water chamber can be effectively removed while the water is being heated. Along with the cordoning off of the Partition wall can also prevent an increase in pressure in the body. A degassing pipe 40 is provided on the partition 13. The degassing tube 40 forms an opening at one end on the lower side of the partition wall and extends upwardly out of the body 10. The interior of the degassing pipe 40 forms the degassing line 30. The degassing pipe 40 can quickly discharge the warm gas in the upper part of the lower water chamber 15.

Der Wasserauslass 12 befindet sich auf einer Seite der unteren Wasserkammer 15. Die untere Wasserkammer weist nahe dem Wasserauslass eine Verengung 152 auf, die in Richtung des Wasserauslasses einen sich reduzierenden Durchflussbereich hat. Auf einer Einlassseite der Verengung in der unteren Wasserkammer ist eine Mischungsaussparung 154 vorgesehen. Da nach der Erwärmung durch die Heizung das warme Wasser über dem kalten Wasser steht, wird das Wasser sogar in der unteren Wasserkammer 15 wegen der Temperatur geschichtet. Dadurch bewegt sich das Wasser bei der Abfuhr zunächst in der Mischungsaussparung 154 hin und her, bevor es über die Verengung 152 aus dem Wasserauslass 12 abgeführt wird, um die Temperatur des abgeführten Wassers zu stabilisieren.The water outlet 12 is located on one side of the lower water chamber 15. The lower water chamber has, near the water outlet, a constriction 152 which has a reducing flow area in the direction of the water outlet. A mixing recess 154 is provided on an inlet side of the constriction in the lower water chamber. Since, after being heated by the heater, the warm water stands above the cold water, the water is even stratified in the lower water chamber 15 because of the temperature. As a result, the water initially moves back and forth in the mixing recess 154 during discharge before it is discharged from the water outlet 12 via the constriction 152 in order to stabilize the temperature of the discharged water.

Der Wasserauslass 12 ist nach oben ausgerichtet, und ein Wasserauslassende der Verengung 152 ist derart schräg nach unten angeordnet, dass das Wasserauslassende der Verengung auf eine Füllungsaussparung 156 ausgerichtet ist und sich der Wasserauslass 12 gerade oberhalb der Füllungsaussparung 156 befindet. Die Füllungsaussparung 156 kann das abgeführte Wasser verlangsamen und die Strömung glätten.The water outlet 12 is oriented upward, and a water outlet end of the constriction 152 is disposed obliquely downward such that the water outlet end of the constriction is oriented towards a filling recess 156 and the water outlet 12 is just above the filling recess 156. The fill recess 156 can slow the drained water and smooth the flow.

Die Heizung 20 umfasst ein gewunden ausgebildetes Heizungsrohr, das die Erwärmungsfläche wirksam vergrößert. In der unteren Wasserkammer 15 ist seitlich des Heizungsrohrs eine Barriere 17 vorgesehen. Die Barriere 17 führt die Wasserströmung so, dass sie entlang des Heizungsrohrs fließt und damit die Erwärmungseffizienz erhöht wird.The heater 20 comprises a coiled heating pipe that effectively increases the heating surface. In the lower water chamber 15, a barrier 17 is provided on the side of the heating pipe. The barrier 17 leads the Water flow so that it flows along the heating pipe, thus increasing the heating efficiency.

An Boden der unteren Wasserkammer 15 ist ein Wasserabfluss vorgesehen, in dem eine Wasserabführungsanordnung 50 vorgesehen ist. Die Wasserabführungsanordnung umfasst eine Feder 52, einen Verschlussstopfen 54 und eine Basis 56, wobei die Basis 56 in dem Wasserabfluss montiert ist, wobei an der Basis 56 eine Wasseröffnung vorgesehen ist, und wobei durch die Vorspannung der Feder 52 nach unten der Verschlussstopfen 54 von oben die Wasseröffnung verschließt. Wenn nach Bedarf das Wasser im Körper 10 geleert werden muss, wird einfach der Verschlussstopfen 54 nach oben gedrückt, was eine bequeme Reinigung des Körpers ermöglicht.At the bottom of the lower water chamber 15, a water drain is provided in which a water drainage arrangement 50 is provided. The water drainage arrangement comprises a spring 52, a sealing plug 54 and a base 56, the base 56 being mounted in the water drain, a water opening being provided on the base 56, and the sealing plug 54 being preloaded downwards by the spring 52 from above the water opening closes. When the water in the body 10 has to be emptied as required, the sealing plug 54 is simply pushed upwards, which enables the body to be cleaned easily.
