Description

Die Erfindung betrifft eine Raumheizung mit einem Ofen und einem Kanalsystem, wobei der Ofen über das Kanalsystem mit Hohlkammerziegeln an den Wänden eines Gebäudes verbunden ist.
Die aus antiken griechischen und römischen Bauten bekannten Hypokausten bildeten ursprünglich eine Bodenheizung, bei der die Rauchgase einer Feuerstelle als Wärmeträger verwendet wurden. Hierbei handelte es sich somit nicht um eine Warmluftheizung, weil in den Räumen keine warme Luft zirkulierte, sondern die Abgase der Feuerstelle als Strahlungswärme für den Fußboden und die Wände genutzt wurden.
Aus DD 62 423 A5 ist eine Einrichtung zur bedarfsweisen Erwärmung oder Kühlung von Räumen bekannt. Bei dieser ist der Ofen als Warmluftofen ausgebildet, von dem ein einheitlicher Umluftkanal die einzelnen, als Wandelemente ausgebildeten Radiatoren mit Warmluft versorgt. Da die Radiatoren in den Räumen des Gebäudes keine Rücklaufleitung haben, muss zur Vermeidung eines Wärmestaus in den Radiatoren die Wärmezufuhr durch Absperrschieber reguliert werden.
In DE 802 017 B ist eine Heiz- und Kühleinrichtung für ein- oder mehrstöckige Gebäude beschrieben und dargestellt, die in einer Heizkammer einen Ofen hat und von der über Boden-, Decken- und Wandkanäle, die ineinander übergehen, die heiße Luft in einem offenen System zu einem Kamin nach außen abströmt. Damit ist auch hier kein geschlossenes Kreislaufsystem vorhanden.
Aus US 5 553 604 A ist eine Raumheizung bekannt, bei der an einen Grundofen ein Warmluftkreislauf mit einer Zugsteineinheit angeschlossen ist, deren Kanäle den Warmluftstrom bremsende Rippen haben, die eine rasche Abkühlung bewirken.The invention relates to a space heater with an oven and a duct system, wherein the oven is connected via the channel system with hollow bricks on the walls of a building.
The hypocausts, which are known from ancient Greek and Roman buildings, originally formed a floor heating system using the flue gases of a fireplace as a heat transfer medium. This was therefore not a warm air heating, because in the rooms no warm air circulated, but the exhaust gases of the fireplace were used as radiant heat for the floor and the walls.
Out DD 62 423 A5 is a device for demand heating or cooling of rooms known. In this, the oven is designed as a hot air oven, of which a single air circulation channel supplies the individual, designed as wall elements radiators with hot air. Since the radiators in the rooms of the building have no return line, to prevent heat build-up in the radiators, the heat must be regulated by gate valves.
In DE 802 017 B a heating and cooling device for one- or multi-storey buildings is described and shown, which has a furnace in a heating chamber and from the over floor, ceiling and wall channels, which merge into each other, the hot air in an open system to a fireplace flows outside. There is no closed loop system here.
Out US 5 553 604 A is a space heating is known in which a basic furnace, a hot air circuit is connected to a mortar unit whose channels have the hot air flow braking ribs, which cause a rapid cooling.

Eine Raumheizung mit den Merkmalen des Oberbegriffs des Anspruchs 1 ist in DE 86 00 843 U1 beschrieben und dargestellt. Bei dieser sind an einen Kachelofen Warmluftkanäle angeschlossen, die in einer Wand des Raumes verlegt sind.
CH 677 022 A5 betrifft eine Raumheizung, die aus Hohlelementen zusammengesetzt ist, welche eine Gebäudewand bilden. Die Hohlelemente leiten die Warmluft zunächst vertikal nach oben, wo sie in einen horizontalen Verbindungskanal strömt, aus dem sie vertikal nach unten fällt.
Der Erfindung liegt die Aufgabe zugrunde, eine Raumheizung der eingangs umrissenen Gattung zur Verfügung zu stellen, welche die Möglichkeit bietet, eine Vielzahl von Räumen eines Gebäudes individuell mit Strahlungswärme zu beheizen.
Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, dass das Kanalsystem mehrere, geschlossene und voneinander unabhängige Warmluft-Kreisläufe hat, die an einen Grundofen angeschlossen sind und von denen jeder einen Grundzugkreis bildet, in dem die Warmluft zirkuliert und der zu einer in die Wand eingelassenen Zugsteineinheit führt. Dabei ist vorgesehen, dass jede Zugsteineinheit aus mehreren Hohlkammerziegeln zusammengesetzt und in eine Aussparung der Wand eingelassen ist und zur Bildung einer Heizschlange miteinander verbundene Kanäle hat.
Das System gemäß der Erfindung unterscheidet sich vom Stand der Technik durch den Einsatz eines Grundofens, der als Kachelofen ausgebildet sein kann und von dem jeder Raum mit wenigstens einem eigenen, geschlossenen Warmluft-Kreislauf versorgt wird. Dies lässt eine individuelle Wärmeregulierung zu, beispielsweise mittels einer elektronischen oder mechanischen Steuerung, die für jeden Kreislauf vorgesehen ist. Jede Zugsteineinheit ist aus mehreren, horizontal angeordneten Kanälen zusammengesetzt, die untereinander verbunden sind. In Abhängigkeit von der Zahl der Kanäle ergibt sich hiermit eine vielfach längere Wärmehaltung gegenüber einer herkömmlichen Warmluftheizung.A space heating with the features of the preamble of claim 1 is in DE 86 00 843 U1 described and illustrated. In this tiled stove hot air ducts are connected, which are laid in a wall of the room.
CH 677 022 A5 relates to a space heating, which is composed of hollow elements, which form a building wall. The hollow elements first pass the warm air vertically upwards, where it flows into a horizontal connecting channel, from which it falls vertically downwards.
The invention has for its object to provide a space heater of the type outlined at the outset, which provides the ability to individually heat a variety of rooms of a building with radiant heat.
To achieve this object, the invention provides that the duct system has a plurality of closed and independent hot air circuits, which are connected to a basic furnace and each of which forms a Grundzugkreis in which circulates the hot air and to a recessed in the wall die unit leads. It is provided that each die unit is composed of several hollow bricks and embedded in a recess of the wall and has interconnected channels to form a heating coil.
The system according to the invention differs from the prior art by the use of a base furnace, which can be designed as a tiled stove and from which each room is supplied with at least one separate, closed hot air circuit. This allows individual thermal regulation, for example by means of an electronic or mechanical control provided for each circuit. Each die unit is composed of several horizontally arranged channels which are interconnected. Depending on the number of channels, this results in a much longer heat retention compared to a conventional hot air heating.

Figur 1 zeigt einen Teilschnitt durch ein Gebäude mit einem Kellerraum 10 und einem Raum 12 im darüberliegenden Erdgeschoss, die beide durch eine Decke 14 voneinander getrennt sind. Der Raum 12 im Erdgeschoss hat eine Ziegelwand 16. FIG. 1 shows a partial section through a building with a basement room 10 and a room 12 in the overlying ground floor, both of which are separated by a ceiling 14. The room 12 on the ground floor has a brick wall 16.

Im Kellerraum 10 ist ein Grundofen 18 untergebracht, der als Kachelofen ausgebildet sein kann und beispielhaft in Figur 3 dargestellt ist. Innerhalb der Ummauerung 20 des Grundofens 18 befindet sich in an sich bekannter Weise ein Brennraum 22, der mit Scheiterholz 24, Stückholz oder Pellets als Wärmequelle beschickt wird. Unterhalb des Brennraums 22 befindet sich eine Lufteintrittsöffnung 26, von der ein Grundzug 28 ausgeht, durch den die erwärmte Luft in Pfeilrichtung nach oben strömt und, wie in Figur 1 angedeutet, die Ummantelung 20 durch einen Warmluftzuführkanal 30 verlässt.In the basement room 10, a base oven 18 is housed, which may be formed as a tiled stove and exemplified in FIG. 3 is shown. Within the wall 20 of the base furnace 18 is located in a conventional manner, a combustion chamber 22 which is charged with logs 24, logs or pellets as a heat source. Below the combustion chamber 22 there is an air inlet opening 26, from which a basic draft 28 emanates, through which the heated air flows upwards in the direction of the arrow and, as in FIG FIG. 1 indicated, the casing 20 leaves through a hot air supply duct 30.

In die Ziegelwand 16 ist, wie in Figur 1 weiter angedeutet, eine Aussparung 32 eingearbeitet, die zur Aufnahme einer Zugsteineinheit 34 dient. Eine solche Zugsteineinheit 34 ist im Beispiel der Figur 4 dargestellt und hat hier insgesamt drei horizontal angeordnete Kanäle 36, die miteinander verbunden sind und dadurch eine Heizschlange bilden. Jeder Kanal 36 ist aus mehreren Hohlkammerziegeln 38 zusammengesetzt, die schematisch in Figur 5 zu erkenne sind.In the brick wall 16 is, as in FIG. 1 further indicated, a recess 32 incorporated, which serves to receive a draft block unit 34. Such a punch unit 34 is in the example of FIG. 4 shown here and has a total of three horizontally disposed channels 36 which are interconnected and thereby form a heating coil. Each channel 36 is composed of a plurality of hollow bricks 38, which are schematically shown in FIG FIG. 5 to recognize are.

In der Schnittdarstellung der Figur 1 ist zu erkennen, dass der den Grundofen 16 verlassende Warmluftkanal 30 durch die Decke 14 in die Ziegelwand 16 führt, in der er vertikal zu dem obersten Kanal 36 gelangt. In diesen tritt die warme Luft durch eine Öffnung 40 ein und strömt über den mittleren und den unteren Kanal 36 zu einem Austrittsanschluss 42. Dabei gibt die durchströmende Warmluft ihre Strahlungwärme 44 (vgl. Figur 6) an den Raum 12 ab.In the sectional view of FIG. 1 It can be seen that the hot air duct 30 leaving the basic oven 16 leads through the ceiling 14 into the brick wall 16 in which it passes vertically to the uppermost channel 36. In these, the warm air enters through an opening 40 and flows through the middle and the lower channel 36 to an outlet port 42. Here, the hot air flowing through their radiation heat 44 (see. FIG. 6 ) to the room 12.

Die auf diese Weise abgekühlte Luft gelangt über den Austrittsanschluss 42, wie Figur 1 weiter zeigt, in einen Kanal 46, der in den Zug 28 des Grundofens 18 zurückströmt. Unter dem Brennraum 22 gelangt die zurückgeführte Luft wieder in den Bereich der Lufteintrittsöffnung 26, wodurch der Kreislauf 48 geschlossen ist.The cooled air in this way passes through the outlet port 42, as FIG. 1 Further, in a channel 46, which flows back into the train 28 of the base furnace 18. Under the combustion chamber 22, the returned air passes back into the region of the air inlet opening 26, whereby the circuit 48 is closed.

In Figur 1 ist angedeutet, dass vom Grundzug 28 ein weiterer Kreislauf 48' mit eigenem Warmluftkanal 30' und eigenem Rückströmkanal 46' zu einer zweiten Zugsteineinheit 34' in den Raum 12 des Gebäudes führt. In diesem sind gemäß Beispiel der Figur 2 zur Erwärmung der einzelnen Räume mehrere Zugsteineinheiten 34, 34', 34", ... vorgesehen, die unabhängig voneinander eigene Kreisläufe 48 haben, von denen jeder eine eigene elektronische oder mechanische Steuerung hat, was in Figur 1 durch die beiden Ventile 50 angedeutet ist.In FIG. 1 it is indicated that from the main draw 28 a further circuit 48 'with its own hot air duct 30' and its own return flow channel 46 'leads to a second draft stone unit 34' in the space 12 of the building. In this are according to example of the FIG. 2 for heating the individual rooms several tamping units 34, 34 ', 34 ", ... provided, which independently have their own circuits 48, each of which has its own electronic or mechanical control, which in FIG. 1 is indicated by the two valves 50.

Wie Figur 1 zeigt, hat der Brennraum 22 im oberen Bereich eine Austrittsöffnung 52 für die Rauchgase, die über ein Rohr 54 durch einen nicht weiter gezeigten Kamin nach außen abgeleitet werden.As FIG. 1 shows, the combustion chamber 22 has an outlet opening 52 for the flue gases in the upper region, which are discharged via a pipe 54 through a not further shown fireplace to the outside.
