Description

Technisches Gebiettechnical field

Die vorliegende Erfindung betrifft eine Wasser zirkulierende Versorgungsvorrichtung, insbesondere eine Versorgungsvorrichtung, die zur Demonstration der Funktion einer intelligenten Toilette zirkulierendes Wasser bereitstellt.The present invention relates to a water circulating supply device, more particularly to a supply device that provides circulating water for demonstrating the function of an intelligent toilet.

Stand der TechnikState of the art

Wenn intelligente Toiletten, wie sie zum Beispiel aus der CN 106 677 304 A bekannt sind, auf Messen, in Ausstellungsräumen, Einkaufszentren, Regalen usw. vorgeführt werden, ist es nicht einfach, sie an eine Wasserleitung anzuschließen, und noch schwieriger, sie mit dem Abflussrohr zu verbinden. Daher ist es nicht möglich, die Funktionen einer intelligenten Toilette zu demonstrieren. Es gibt damit keinerlei Möglichkeit, die Wasseraustrittswirkungen bei der femininen und hinteren Reinigung, der Selbstreinigung und dergleichen der intelligenten Toilette zu demonstrieren. Dies führt dazu, dass die Verbraucher die Funktionen der intelligenten Toilette bezüglich der Wasseraustrittswirkung nicht immer genau einschätzen können. Um dieses Problem zu lösen, greifen die Anbieter derzeit auf Videos zurück, um den Verbrauchern die Funktionsweise der intelligenten Toilette zu zeigen. Hierzu zeichnen sie die Prüfung des Wasseraustritts der intelligenten Toilette im Werkslabor auf und demonstrieren ihn dann den Verbrauchern über den Bildschirm, auf dem das Video abgespielt wird. Die Funktionsweise der intelligenten Toilette, die durch diese Art der Videovorführung gezeigt wird, findet jedoch nicht direkt vor den Augen des Verbrauchers statt, und es ist schwer zu sagen, ob sie echt oder manipuliert ist. Die Verbraucher sind teilweise noch nicht in der Lage, ein Verständnis für die Funktionen der intelligenten Toilette zu bekommen.If intelligent toilets, such as those from the CN 106 677 304 A are known to be demonstrated at fairs, showrooms, shopping malls, shelves, etc., it is not easy to connect them to a water pipe and even more difficult to connect them to the drain pipe. Therefore it is not possible to demonstrate the functions of a smart toilet. Thus, there is no way to demonstrate the water leakage effects in the feminine and rear cleaning, self-cleaning and the like of the intelligent toilet. This As a result, consumers cannot always accurately assess the functions of the intelligent toilet in terms of the water leakage effect. Currently, to solve this problem, vendors resort to videos to show consumers how the smart toilet works. To do this, they record the water leakage test of the smart toilet in the factory laboratory and then demonstrate it to consumers through the screen playing the video. However, the workings of the smart toilet shown through this type of video demonstration do not take place directly in front of the consumer's eyes and it is difficult to tell whether they are real or fake. Some consumers are not yet able to understand the functions of the intelligent toilet.

Aus der CN 107 802 125 A ist eine Wasser zirkulierende Versorgungseinrichtung zur Demonstration von Küchen- und Badprodukten, beispielsweise Armaturen, bekannt. Die Versorgungsvorrichtung weist einen Wasserbehälter mit Wasser auf, das mittels einer Pumpe dem Küchen- oder Badprodukt zugeleitet wird. Für die Demonstration der Funktion einer intelligenten Toilette ist die bekannte Versorgungseinrichtung nicht geeignet.From the CN 107 802 125 A discloses a water circulating supply for demonstrating kitchen and bath products such as faucets. The supply device has a water tank with water that is supplied to the kitchen or bath product by means of a pump. The well-known supply device is not suitable for demonstrating the function of an intelligent toilet.

Ausführungsbeispiel der Erfindungembodiment of the invention

Wie in Fig. 1 bis 7 dargestellt, wird eine Wasser zirkulierende Versorgungsvorrichtung zur Demonstration der Funktion einer intelligenten Toilette gezeigt, mittels der das Wasser aus einem WC-Becken A der intelligenten Toilette gepumpt und anschließend über einen in einem WC-Sitz B der intelligenten Toilette angeordneten Wasserweg zum Waschen des menschlichen Körpers zurück in das WC-Becken A der intelligenten Toilette gespritzt werden kann. Alternativ fließt das aus dem WC-Becken A der intelligenten Toilette gepumpte Wasser direkt zurück in das WC-Becken A der intelligenten Toilette, wodurch ein Zirkulieren bzw. Wiederverwenden von Wasser erreicht wird. Der im WC-Sitz B der intelligenten Toilette angeordnete Wasserweg zum Waschen des menschlichen Körpers ist der jeweilige Wasserauslasskanal der Reinigungseinrichtung im WC-Sitz der intelligenten Toilette. Er kann, abhängig vom Aufbau der Reinigungseinrichtung im WC-Sitz der intelligenten Toilette, der Wasserweg für die feminine und hintere Reinigung oder auch der Selbstreinigungswasserweg der Reinigungseinrichtung sein. Die erfindungsgemäße Vorrichtung versorgt nur die Reinigungseinrichtung des WC-Sitzes der intelligenten Toilette mit Wasser.As in Figures 1 to 7 1, a water circulating supply device for demonstrating the function of a smart toilet is shown, by means of which the water is pumped from a toilet bowl A of the smart toilet and then through a water path arranged in a toilet seat B of the smart toilet for washing the human body can be squirted back into the toilet bowl A of the smart toilet. Alternatively, the water pumped from the smart toilet bowl A directly flows back into the smart toilet bowl A, thereby achieving water circulation. The water path for washing the human body arranged in the toilet seat B of the smart toilet is each water outlet channel of the cleaning device in the toilet seat of the smart toilet. Depending on the structure of the cleaning device in the toilet seat of the intelligent toilet, it can be the water path for feminine and rear cleaning or the self-cleaning water path of the cleaning device. The device according to the invention only supplies the cleaning device of the toilet seat of the intelligent toilet with water.

Die Wasser zirkulierende Versorgungsvorrichtung zur Demonstration der Funktion der intelligenten Toilette umfasst ein Gehäuse 10 und eine Dichtungsmanschette 20, wobei auf einer Rückseite des Gehäuses 10 ein WC-Beckenanschluss 12 zum Aufstecken auf eine Abflussrohrmündung A01 des WC-Beckens A der intelligenten Toilette vorgesehen ist, und wobei die Dichtungsmanschette 20 am Rand des WC-Beckenanschlusses 12 zum Abdichten der Abflussrohrmündung A01 des WC-Beckens angeordnet ist. Das Gehäuse 10 kann also direkt auf die Abflussrohrmündung A01 des WC-Beckens aufgesetzt werden, wobei die Dichtungsmanschette 20 für eine Dichtverbindung sorgt.The water circulating supply device for demonstrating the function of the intelligent toilet comprises a housing 10 and a sealing collar 20, with a toilet bowl connection 12 for plugging onto a drain pipe mouth A01 of the toilet bowl A of the intelligent toilet being provided on a rear side of the housing 10, and wherein the sealing collar 20 is arranged on the edge of the toilet bowl connection 12 for sealing the drain pipe mouth A01 of the toilet bowl. The housing 10 can therefore directly on the Drain pipe mouth A01 of the toilet bowl are placed, the sealing sleeve 20 ensures a sealed connection.

Am Gehäuse 10 sind ein Wasserzuleitungsanschluss 14 und ein Rückflussanschluss 16 angeordnet, die beide mit dem WC-Beckenanschluss kommunizieren. Ferner umfasst die erfindungsgemäße Vorrichtung eine Wasserpumpe 30 und ein Einwegventil 40, wobei ein Wassereinlass der Wasserpumpe 30 an den Wasserzuleitungsanschluss 14 (direkt oder über eine Wasserleitung) angeschlossen ist, so dass die Wasserpumpe 30 über den Wasserzuleitungsanschluss 14 das Wasser aus dem WC-Becken A pumpen kann. Ein Wasserauslass der Wasserpumpe 30 teilt sich in zwei Wasserwege auf, wobei der erste Wasserweg zum Anschließen an den im WC-Sitz B der intelligenten Toilette angeordneten Wasserweg zum Waschen des menschlichen Körpers verwendet wird und der Wasserzufuhr zu der Reinigungseinrichtung des WC-Sitzes der intelligenten Toilette dient sowie ferner es der Reinigungseinrichtung ermöglicht, die entsprechende Spülung durchzuführen. Der zweite Wasserweg ist über das Einwegventil 40 an den Rückflussanschluss 16 angeschlossen, wobei sich das Einwegventil 40 normalerweise im geschlossenen Zustand befindet. Folglich wird das von der Wasserpumpe 30 abgepumpte Wasser über den Rückflussanschluss 16 wieder in das WC-Becken A zurückgeleitet, wenn die Reinigungseinrichtung des WC-Sitzes der intelligenten Toilette nicht betrieben wird.A water supply connection 14 and a return flow connection 16 are arranged on the housing 10, both of which communicate with the toilet bowl connection. Furthermore, the device according to the invention comprises a water pump 30 and a one-way valve 40, with a water inlet of the water pump 30 being connected to the water supply connection 14 (directly or via a water line), so that the water pump 30, via the water supply connection 14, draws the water from the toilet bowl A can pump. A water outlet of the water pump 30 is divided into two water paths, the first water path used for connecting to the water path arranged in the toilet seat B of the intelligent toilet for washing the human body and the water supply to the cleaning device of the toilet seat of the intelligent toilet serves and also allows the cleaning device to carry out the appropriate flushing. The second water path is connected to the return port 16 via the one-way valve 40, which one-way valve 40 is normally in the closed state. Consequently, the water pumped out by the water pump 30 is returned to the toilet bowl A via the return port 16 when the toilet seat cleaner of the intelligent toilet is not operated.

Wenn die Funktion des WC-Sitzes der intelligenten Toilette demonstriert werden soll, wird die Wasserpumpe 30 eingeschaltet, um Wasser zu pumpen. Die Wasserpumpe 30 pumpt das Wasser aus dem WC-Becken A der intelligenten Toilette. Wenn der im WC-Sitz B der intelligenten Toilette angeordnete Wasserweg zum Waschen des menschlichen Körpers geöffnet wird (d.h. die Reinigungseinrichtung aktiviert ist), tritt das Wasser durch den ersten Wasserweg in den im WC-Sitz der intelligenten Toilette angeordneten Wasserweg zum Waschen des menschlichen Körpers ein, da der zweite Wasserweg durch das Einwegventil 40 unterbrochen ist, wodurch eine Reinigung ermöglicht wird. Wenn der im WC-Sitz der intelligenten Toilette angeordnete Wasserweg zum Waschen des menschlichen Körpers geschlossen wird, sind zu diesem Zeitpunkt sowohl der erste als auch der zweite Wasserweg unterbrochen. Deshalb steigt der Wasserdruck in den Wasserwegen weiter an. Schließlich öffnet das Wasser das Einwegventil 40 und fließt durch das Einwegventil 40 und sodann über den Rückflussanschluss 16 zurück in das WC-Becken A der intelligenten Toilette.When the function of the smart toilet seat is to be demonstrated, the water pump 30 is turned on to pump water. The water pump 30 pumps the water from the toilet bowl A of the smart toilet. When the human body washing waterway arranged in the toilet seat B of the intelligent toilet is opened (ie, the cleaning device is activated), the water enters the human body washing waterway arranged in the toilet seat of the intelligent toilet through the first waterway because the second water path is cut off by the one-way valve 40, allowing cleaning. At this time, when the human body washing water path arranged in the toilet seat of the intelligent toilet is closed, both the first and second water paths are cut off. As a result, the water pressure in the waterways continues to rise. Finally, the water opens the one-way valve 40 and flows through the one-way valve 40 and then back into the toilet bowl A of the smart toilet via the return port 16 .

Vorzugsweise umfasst das Einwegventil 40 einen Ventilkörper 42, einen Schließkörper 44 und ein elastisches Element 46, wobei der Ventilkörper 42 über einen Wassereinlasskanal 421, einen Wasserauslasskanal 422 und einen Wasserableitungskanal 423 verfügt. Der Schließkörper 44 und das elastische Element 46 sind in dem Ventilkörper 42 derart angeordnet, dass das elastische Element 46 den Schließkörper 44 vorspannt, um den Wassereinlasskanal 421 zu schließen. Der Wasserableitungskanal 423 und der Wassereinlasskanal 421 kommunizieren miteinander. Der erste Wasserweg verläuft vom Wasserauslass der Wasserpumpe 30 durch den Wassereinlasskanal 421 und den Wasserableitungskanal 423 hindurch und ist mit dem im WC-Sitz B der intelligenten Toilette angeordneten Wasserweg zum Waschen des menschlichen Körpers verbunden. Im geöffneten Zustand des Einwegventils 40 verläuft der zweite Wasserweg vom Wasserauslass der Wasserpumpe 30 durch den Wassereinlasskanal 421 und den Wasserauslasskanal 422 hindurch und ist mit dem Rückflussanschluss 16 verbunden. Es versteht sich, dass der Wasserauslass der Wasserpumpe 30 auch direkt in zwei Stränge geteilt sein kann, von denen der eine an den Wassereinlasskanal 421 und der andere an den Rückflussanschluss 16 angeschlossen ist. Dies bedeutet, dass der Wasserableitungskanal 423 nicht notwendigerweise am Ventilkörper des Einwegventils 40 angeordnet sein muss. Ferner kann das Einwegventil bei der erfindungsgemäßen Vorrichtung auch eine andere Konstruktion aufweisen.The one-way valve 40 preferably comprises a valve body 42 , a closing body 44 and an elastic element 46 , the valve body 42 having a water inlet channel 421 , a water outlet channel 422 and a water drainage channel 423 . The closing body 44 and the elastic member 46 are arranged in the valve body 42 such that the elastic member 46 biases the closing body 44 to close the water inlet passage 421 . The water drainage channel 423 and the water inlet channel 421 communicate with each other. The first water path runs from the water outlet of the water pump 30 through the water inlet passage 421 and the water drainage passage 423 and is connected to the human body washing water path arranged in the toilet seat B of the intelligent toilet. In the open In the state of the one-way valve 40 , the second water path passes from the water outlet of the water pump 30 through the water inlet channel 421 and the water outlet channel 422 and is connected to the return port 16 . It goes without saying that the water outlet of the water pump 30 can also be divided directly into two branches, one of which is connected to the water inlet channel 421 and the other to the return flow connection 16 . This means that the water drainage channel 423 does not necessarily have to be arranged on the valve body of the one-way valve 40 . Furthermore, the one-way valve in the device according to the invention can also have a different construction.

Vorzugsweise umfasst der Ventilkörper 42 ein Bodengehäuse 424 und eine obere Abdeckung 425, die das Bodengehäuse von oben abdeckt, wobei der Wassereinlasskanal 421 am unteren Ende des Bodengehäuses 424 vorgesehen ist, wobei der Wasserableitungskanal 423 seitlich am Bodengehäuse 424 angeordnet ist, wobei der Wasserauslasskanal 422 an der oberen Abdeckung 425 angeordnet ist, wobei der Schließkörper 44 vertikal bewegbar in dem Bodengehäuse 424 angeordnet ist, und wobei das elastische Element 46 zwischen dem Schließkörper 44 und der oberen Abdeckung 425 gespannt ist. Im Normalzustand drückt das elastische Element 46 den Schließkörper 44 nach unten, um den Wassereinlasskanal 421 zu schließen, so dass das Wasser aus dem Wasserableitungskanal 423 herausfließt. Kann das Wasser nicht aus dem Wasserableitungskanal 423 abfließen, steigt der Wasserdruck im Wassereinlasskanal 421 an und drückt den Schließkörper 44 nach oben, so dass das Wasser aus dem Wasserauslasskanal 422 herausfließt.The valve body 42 preferably comprises a bottom housing 424 and a top cover 425, which covers the bottom housing from above, with the water inlet channel 421 being provided at the lower end of the bottom housing 424, with the water drainage channel 423 being arranged on the side of the bottom housing 424, with the water outlet channel 422 on of the top cover 425, with the closure body 44 being vertically movably disposed in the bottom case 424, and with the elastic member 46 stretched between the closure body 44 and the top cover 425. In the normal state, the elastic member 46 pushes down the closing body 44 to close the water inlet channel 421 so that the water flows out from the water drainage channel 423 . If the water cannot drain from the water drainage channel 423 , the water pressure in the water inlet channel 421 increases and pushes the closing body 44 upwards, so that the water flows out from the water outlet channel 422 .

Vorzugsweise ist an dem Bodengehäuse 424 eine mit einem Dichtungsende des Schließkörpers 44 korrespondierende Vertiefung 426 vorgesehen. Wenn das Dichtungsende des Schließkörpers 44 in der Vertiefung 426 sitzt sind der Wassereinlasskanal und das Einwegventil geschlossen. Das Einwegventil wird geöffnet, wenn das Wasser nach oben fließt und den Schließkörper öffnet, so dass sich das Dichtungsende aus der Vertiefung herausbewegt. Bei dem vorliegenden Ausführungsbeispiel ist am Dichtungsende des Schließkörpers 44 ein Dichtring aufgesetzt, der eine bessere Abdichtung gewährleistet.A depression 426 corresponding to a sealing end of the closing body 44 is preferably provided on the bottom housing 424 .
