Abstract

The heating device has an insert (10) by means of which water flowing in through an inlet opening (6) is calmed before it proceeds downwards to an electric heater (3). The heated water once again reaches the upper part of the interior (1e) of the heating device, and passes along a separating wall (1c) to the outlet (7) which is also located in the upper region. Through this arrangement it is ensured that even with a low constructional height and compact design, evenly heated water is available for as long as possible, and this water can be fed via a hose pipe to the nozzle arm of a bidet. <IMAGE>

Description

Die Erfindung betrifft eine Heizeinrichtung nach dem Oberbegriff des unabhängigen Patentanspruchs 1.The invention relates to a heating device according to the preamble of independent claim 1.

Allgemein bekannt sind Heizeinrichtungen, auch Heisswasserspeicher oder Boiler genannt, bei denen durch ein Zulaufrohr unten in einen Innenkessel kaltes Wasser eintritt und durch Verdrängung das heisse Wasser durch einen am oberen Ende des Innenkessels angebrachten Auslauf zum Abfluss gebracht wird. Weiter ist durch die CH-A 597 447 eine Heizeinrichtung bekannt geworden, die einen Beheizungsraum, in dem das Zuströmende Kaltwasser in der Art einer Tauchsiederheizung erwärmt wird und einen nachgeschalteten Vorratsraum aufweist, in dem das erwärmte Duschwasser für den Gebrauch bereit gehalten wird. Durch diese Unterteilung des Innenraumes der Heizeinrichtung soll eine gleichmässige Wassertemperatur im Vorratsraum sichergestellt werden. Der Vorratsraum und der Beheizungsraum werden durch ein liegendes Rohrstück unterteilt, das eine Gegenstromführung des Wassers erlaubt. Entsprechend sind der Auslass des Wassers aus dem Vorratsraum und der Einlass des kalten Wassers auf der gleichen Seite des Rohrstücks angebracht. Diese Heizeinrichtung besitzt eine zylindrische Aussenform und eignet sich daher für den Einbau in ein entsprechendes rohrförmiges Installationselement, in dem auch die weiteren Vorrichtungen für die Unterdusche untergebracht sind und das im hohlen Ansatz des Klosettsitzes montiert wird. Hingegen besteht bei dieser Heizeinrichtung die Schwierigkeit, dass durch den oben erwähnten Aufbau die äussere Formgebung weitgehend festgelegt ist. Klosettsitze mit einer solchen Heizeinrichtung besitzen entsprechend einen vergleichsweise hohen Ansatz, der heutigen Einrichtungen in ästhetischer Hinsicht vielfach nicht gerecht wird. Wünschbar wäre insbesondere ein Klosettsitz mit einer grösseren und flacheren Oberseite und einem entsprechend niedrigeren Ansatz.Heating devices, also known as hot water storage tanks or boilers, are well known, in which cold water enters through an inlet pipe at the bottom of an inner boiler and the hot water is displaced through a spout attached to the upper end of the inner boiler. Furthermore, CH-A 597 447 has disclosed a heating device which has a heating room in which the inflowing cold water is heated in the manner of a immersion heater and a downstream storage room in which the heated shower water is kept ready for use. This subdivision of the interior of the heating device an even water temperature in the storage room should be ensured. The storage room and the heating room are divided by a horizontal pipe section that allows the water to flow counter-current. Accordingly, the outlet of the water from the storage room and the inlet of the cold water are located on the same side of the pipe section. This heating device has a cylindrical outer shape and is therefore suitable for installation in a corresponding tubular installation element, in which the further devices for the shower are housed and which is mounted in the hollow attachment of the toilet seat. On the other hand, there is the difficulty with this heating device that the external shape is largely determined by the above-mentioned structure. Toilet seats with such a heating device accordingly have a comparatively high approach, which often does not do justice to today's facilities in terms of aesthetics. In particular, a toilet seat with a larger and flatter top side and a correspondingly lower attachment would be desirable.

Der Erfindung liegt die Aufgabe zugrunde, eine Heizeinrichtung zu schaffen, die im Hinblick auf die äussere Formgebung weniger Einschränkungen bedingt, und die dennoch für eine Unterdusche eines Wasserklosetts geeignet ist. Die Aufgabe wird durch die Erfindung gemäss Anspruch 1 gelöst.The object of the invention is to create a heating device which has fewer restrictions with regard to the external shape and which is nevertheless suitable for a shower in a water closet. The object is achieved by the invention according to claim 1.

Bei der erfindungsgemässen Heizeinrichtung wird das mit Netzdruck in das Innere des Gehäuses einströmende Wasser unmittelbar nach dem Einlauf weitgehend beruhigt. Ohne dass eine Unterteilung in einen Beheizungsraum und einen Vorratsraum erforderlich ist, lässt sich auf einem vergleichsweise kurzen Strömungsweg eine gleichmässige Erwärmung des Wassers auf die gewünschte Körpertemperatur erreichen. Im Gegensatz zu den bekannten Heizvorrichtungen sind bei der erfindungsgemässen Einrichtung sowohl der Wassereinlauf als auch der Wasserauslauf im oberen Bereich des Gehäuses angeordnet. Das einströmende kalte Wasser strömt somit im wesentlichen von oben nach unten und das warme Wasser von unten nach oben zum Auslauf. Der Innenraum und entsprechend auch die äussere Form der Heizeinrichtung können weitgehend frei gewählt werden. Insbesondere ist ein tropfenförmiger Querschnitt und eine niedrigere Höhe des Gehäuses der Heizeinrichtung möglich, was im Hinblick auf die Formgebung des Klosettsitzes besonders vorteilhaft ist.In the heating device according to the invention, the water flowing into the interior of the housing with network pressure is largely calmed down immediately after the inlet. Without a subdivision into a heating room and a storage room, uniform heating of the water to the desired body temperature can be achieved in a comparatively short flow path. In contrast to the known heating devices, both the water inlet and the water outlet are arranged in the upper region of the housing in the device according to the invention. The inflowing cold water essentially flows from top to bottom and the warm water from bottom to top to the outlet. The interior and, accordingly, the outer shape of the heating device can largely be chosen freely. In particular, a drop-shaped cross section and a lower height of the housing of the heating device are possible, which is particularly advantageous with regard to the shape of the toilet seat.

Eine besonders wirksame Beruhigung des einströmenden kalten Wassers wird dann erreicht, wenn nach einer Weiterbildung der Erfindung in den Innenraum des Gehäuses ein Einsatz mit einer horizontalen Platte vorgesehen ist, wobei diese sich horizontal erstreckende Platte Löcher für den Durchgang des nach unten strömenden Wassers aufweist. Die Wirkung der Beruhigung wird noch weiter erhöht, wenn diese Platte nach oben gerichtete Vorsprünge besitzt.A particularly effective calming of the inflowing cold water is achieved if, according to a further development of the invention, an insert with a horizontal plate is provided in the interior of the housing, this horizontally extending plate having holes for the passage of the water flowing downwards. The effect of sedation is increased even more when this plate is after has projections directed above.

Nach einer Weiterbildung der Erfindung weist der Einsatz nach oben gerichtete Stege auf, an denen im Abstand zu der Platte eine Trennwand angeordnet ist, welche das einströmende kalte Wasser nach oben gegen das Gehäuse umlenkt. Das kalte Wasser strömt somit unmittelbar nach dem Einlass kurzfristig nach oben und wird durch die Gehäusewandung dann nach unten umgelenkt. Auch diese Massnahme trägt dazu bei, dass das mit hohem Druck und vergleichsweise hoher Geschwindigkeit einströmende Wasser schnell beruhigt wird.According to a development of the invention, the insert has upwardly directed webs, on which a partition is arranged at a distance from the plate, which deflects the inflowing cold water upwards against the housing. The cold water flows upwards for a short time immediately after the inlet and is then deflected downwards through the housing wall. This measure also helps to quickly calm the water flowing in at high pressure and at a comparatively high speed.

Nach einer Weiterbildung der Erfindung ist der Thermostat ein Kapillarrohr-Thermostat und dieser ist über dem Heizstab angeordnet. Versuche haben gezeigt, dass durch diese Anordnung trotz der unkonventionellen Bauweise eine sehr gute Temperaturcharakteristik erreicht wird. Weitere vorteilhafte Merkmale ergeben sich aus den übrigen abhängigen Ansprüchen und der nachfolgenden Beschreibung.According to a development of the invention, the thermostat is a capillary tube thermostat and this is arranged above the heating element. Tests have shown that this arrangement achieves a very good temperature characteristic despite the unconventional design. Further advantageous features result from the remaining dependent claims and the following description.

Die Heizeinrichtung weist ein thermisch gut isolierendes Kunststoffgehäuse 1 aus einem Deckel 1a und einen Gehäusekörper 1b auf. Der Deckel 1a besitzt eine an sich bekannte Schmelzsicherung 5 und ist mittels Vibrationsschweissung mit dem Körper 1 allseitig dicht verbunden. In dem Hohlraum 1e des Gehäuses 1 sind ein zu einer ebenen Schleife gebogener Heizstab 3 sowie ein Kapillarrohr-Thermostat 2 eingesetzt, die am Gehäusekörper 1b befestigt sind und die gehäuseaussenseitig in an sich bekannter Weise mit elektrischen Steuer- und Versorgungsleitungen 4 und 12 verbunden sind. Wie insbesondere aus Fig. 2 ersichtlich, ist der Heizstab 3 im unteren Bereich des Hohlraumes 1e angeordnet und befindet sich der Thermostat 2 über diesem Heizstab 3.The heating device has a thermally well-insulating plastic housing 1 made of a cover 1a and a housing body 1b. The cover 1 a has a fuse 5 known per se and is tightly connected to the body 1 on all sides by means of vibration welding. In the cavity 1e of the housing 1, a heating rod 3 bent into a flat loop and a capillary tube thermostat 2 are inserted, which are attached to the housing body 1b and which are connected to the outside of the housing in a manner known per se with electrical control and supply lines 4 and 12. As can be seen in particular from FIG. 2, the heating element 3 is arranged in the lower region of the cavity 1e and the thermostat 2 is located above this heating element 3.

Für die Zuführung des kalten Wassers ist ein Anschluss 13 vorgesehen, der an einem Gehäusekörper 1b angeformten Ueberlaufkanal 8 angeformt ist. Dieser Kanal 8 führt gemäss Fig. 3 nach unten und mit einer Oeffnung 8a nach aussen. Im oberen Teil des Kanals 8 befinden sich ein Rohrunterbrecher 9, der in an sich bekannter Weise durch eine freie Strecke zwischen der Mündung 13a des Anschlussteils 13 und einer Wassereinlauföffnung 6 gebildet wird. Die minimale Länge dieser Strecke ist in der Regel vorgeschrieben. Bei einem Unterdruck in der Kaltwasserleitung wird durch den Rohrunterbrecher verhindert, dass Wasser aus dem Innenraum 1e in das Wasserversorgungsnetz gelangen kann. In einem solchen Fall wird lediglich Luft durch die Oeffnung 8a in das Wasserversorgungsnetz gesaugt. Der Rohrunterbrecher 9 bildet hier ebenfalls eine Ueberlaufsicherung. Durch die Oeffnung 6 und durch den Kanal 8 ist der obere Bereich des Hohlraumes 1e mit der Aussenluft verbunden, so dass sich in diesem Raum 1e kein gefährlicher Ueberdruck aufbauen kann. Bei der erfindungsgemässen Heizeinrichtung sind somit herstellungstechnisch vorteilhaft ein Rohrunterbrecher und eine Ueberlaufsicherung realisiert. Der Verlauf des einströmenden kalten Wassers durch die Oeffnung 6 ist in den Fig. 2 und 5 durch die Pfeile 14a, 14b und 14c angedeutet. Dieser Strömungsverlauf führt mit Hilfe eines Einsatzes 10 zu einer schnellen Beruhigung des einströmenden Wassers. Das die Oeffnung 6 horizontal durchströmende Wasser gelangt in eine im oberen Teil des Raumes 1e angeordnete Vorkammer 10a, in welcher das Wasser in Richtung des Pfeils 14b nach oben sowie seitlich nach links und rechts in Richtung der Pfeile 14b abgelenkt wird. Diese Strömungsrichtung wird wesentlich durch eine Trennwand 10g des Einsatzes 10 sowie durch den Gehäusekörper 1b beeinflusst. Anschliessend strömt das bereits teilweise beruhigte Wasser in Richtung der Pfeile 14c nach unten gegen eine Platte 10d des Einsatzes 10, die eine Mehrzahl von Durchgängen 10e sowie nach oben vorspringende Rippen 10f aufweist. Diese Vorsprünge 10f und Durchgänge 10e beruhigen das Wasser, sodass dieses unterhalb der Platte 10d mit geringer Geschwindigkeit nach unten strömt und durch den Heizkörper 3 erwärmt wird. Das erwärmte Wasser gelangt durch den natürlichen Auftrieb nach oben und etwa in Richtung des Pfeiles 14d (Fig. 2) entlang einer Wand 1c zu einer einer Auslassöffnung 7, von welcher das erwärmte Wasser über eine hier nicht gezeigte Schlauchleitung zu einem Duscharm gelangt. Die Wand 1c ist am Gehäuse 1 angeformt und gewährleistet, dass im Bereich der beiden Oeffnungen 6 und 7 das erwärmte ausströmende Wasser vom einströmenden kalten Wasser getrennt ist.For the supply of the cold water, a connection 13 is provided, which is integrally formed on an overflow channel 8 molded onto a housing body 1b. According to FIG. 3, this channel 8 leads downwards and with an opening 8a to the outside. In the upper part of the channel 8 there are a pipe interrupter 9 which is formed in a manner known per se by a free path between the mouth 13a of the connection part 13 and a water inlet opening 6. The minimum length of this route is usually prescribed. In the event of a negative pressure in the cold water line, the pipe interrupter prevents water from getting into the water supply network from the interior 1e. In such a case, only air is sucked through the opening 8a into the water supply network. The pipe interrupter 9 also forms an overflow protection here. Through the opening 6 and through the channel 8, the upper region of the cavity 1e is connected to the outside air, so that no dangerous excess pressure can build up in this space 1e. In the case of the heating device according to the invention, a pipe interrupter and an overflow protection are thus advantageously produced. The course of the inflowing cold water through the opening 6 is indicated in FIGS. 2 and 5 by the arrows 14a, 14b and 14c. With the help of an insert 10, this flow pattern quickly calms the inflowing water. The water flowing horizontally through the opening 6 arrives into a prechamber 10a arranged in the upper part of the room 1e, in which the water is deflected upwards in the direction of the arrow 14b and laterally to the left and right in the direction of the arrows 14b. This direction of flow is significantly influenced by a partition 10g of the insert 10 and by the housing body 1b. The already partially calmed water then flows downwards in the direction of the arrows 14c against a plate 10d of the insert 10 which has a plurality of passages 10e and ribs 10f projecting upwards. These projections 10f and passages 10e calm the water so that it flows down below the plate 10d at a low speed and is heated by the heating element 3. The heated water passes through the natural buoyancy upwards and approximately in the direction of arrow 14d (FIG. 2) along a wall 1c to an outlet opening 7, from which the heated water reaches a shower arm via a hose line, not shown here. The wall 1c is integrally formed on the housing 1 and ensures that in the region of the two openings 6 and 7 the heated outflowing water is separated from the inflowing cold water.

Der in den Fig. 5 und 6 gezeigte Einsatz 10 ist als separates Stück aus Kunststoff hergestellt und vor dem Aufsetzen des Deckels 1a in den Gehäusekörper 1b eingesetzt, wobei hier Auflagen 1d am Gehäusekörper 1b diesen Einsatz 10 halten. Wie die Fig. 5 zeigt, ist die Trennwand 10g über zwei parallele Stege 10c mit der Platte 10d verbunden. In der Wand 10g kann ein Durchgang 10b angebracht sein, durch den ebenfalls Wasser von der Kammer 10a nach unten zum Heizkörper 3 gelangen kann.The insert 10 shown in FIGS. 5 and 6 is made as a separate piece of plastic and is inserted into the housing body 1b before the cover 1a is placed on it, with supports 1d on the housing body 1b having this insert 10 hold. As shown in FIG. 5, the partition 10g is connected to the plate 10d via two parallel webs 10c. A passage 10b can be provided in the wall 10g, through which water can likewise get down from the chamber 10a to the radiator 3.

Zur Absicherung kann die Heizeinrichtung selbstverständlich auch eine hier nicht gezeigte Temperaturbegrenzung aufweisen.For protection, the heating device can of course also have a temperature limit, not shown here.

Beim erfindungsgemässen Heisswasserspeicher ist im wesentlichen der gesamte Hohlraum 1e zugleich Heizraum und Vorratsraum. Bei kleinen Aussenmassen kann somit eine vergleichsweise grosse Menge an warmem Durschwasser auf Vorrat gehalten werden.In the hot water tank according to the invention, essentially the entire cavity 1e is at the same time the heating room and the storage room. In the case of small external dimensions, a comparatively large amount of warm flow water can be kept in stock.
