Description

Die Erfindung bezieht sich auf eine Wärmeabgabeeinrichtung nach dem Oberbegriff des Patentanspruchs 1. Derartige Luftspalte zwischen einer Wärmeabgabeeinrichtung und einer Stellwand sieht man vor, um die Erwärmung der Wand durch das Gerät in vorschriftsmäßigen Grenzen zu halten. Ein derartiger Luftspalt soll für eine Durchströmung freigehalten werden.The invention relates to a heat emission device according to the preamble of claim 1. Such air gaps between a heat emission device and a partition are provided in order to keep the heating of the wall by the device within the prescribed limits. Such an air gap should be kept free for a flow.

An Stellwänden hinter Wärmeabgabeeinrichtungen bilden sich oberhalb der Wärmeabgabeeinrichtungen bekanntlich störende unregelmäßige Wandverschmutzungen. Diese werden durch Staubpartikel der Umgebungsluft hervorgerufen, die durch thermischen Auftrieb im Spalt zwischen Stellwand und Wärmeabgabeeinrichtung mitgeführt werden. Die Staubpartikel, die teilweise verschwelt werden, können sich an kälteren Flächen, wie der Stellwand hinter einer Wärmeabgabeeinrichtung, ablagern. Je höher die Strömungsgeschwindigkeit im Spalt, um so ausgeprägter werden die staubfahnenartigen Verschmutzungen an den Wänden.As is known, disturbing irregular wall soiling is formed on partition walls behind heat emission devices. These are caused by dust particles in the ambient air, which are carried by thermal buoyancy in the gap between the partition and the heat emission device. The dust particles, which are partially carbonized, can be deposited on colder surfaces, such as the partition behind a heat emission device. The higher the flow velocity in the gap, the more pronounced the dust plume-like soiling on the walls.

Bei Wärmeabgabeeinrichtungen, bei denen die Stellwand durch Luftströmung in einem Spalt gekühlt werden soll, ist es unzweckmäßig, die Wärmeabgabeeinrichtung bis zur Stellwand völlig abzudecken, da dann nicht mehr sichergestellt wäre, daß die Wand nicht über ein zulässiges Maß aufgeheizt würde.In the case of heat-emitting devices in which the partition wall is to be cooled in a gap by air flow, it is impractical to completely cover the heat-emitting device as far as the partition wall, since it would then no longer be ensured that the wall would not be heated to an admissible extent.

Es ist bereits aus der GB-A-1 029 891 bekannt, über Wärmeabgabeeinrichtungen an der Stellwand eine Luftleiteinrichtung anzubringen, welche die Luft an einem im bestand zu der Stellwand befindlichen Ort aus dem Luftspalt herausleitet. Dabei ist jedoch nachteilig, daß die Luftleiteinrichtung an die Wand montiert werden muß, was häufig insbesondere bei bereits leicht gekrümmten Stellwänden oder für die Anbringung von Halteeinrichtungen nicht geeigneten Stellwänden nicht ohne weiteres möglich ist. Ferner hat diese Luftleiteinrichtung die Gestalt eines Kaminsimses, was für manche Anwendung nicht erwünscht ist.It is already known from GB-A-1 029 891 to attach an air guiding device to the partition by means of heat-emitting devices, which directs the air out of the air gap at a location that is existing to the partition. However, it is disadvantageous that the air guiding device has to be mounted on the wall, which is frequently not readily possible, in particular in the case of partitions which are already slightly curved or partitions which are not suitable for the attachment of holding devices. Furthermore, this air guiding device has the shape of a mantelpiece, which is not desirable for some applications.

Aus der FR-A-2 037 643 ist eine Wärmeabgabeeinrichtung mit einer Verkleidung bekannt, an welcher ein einstückig angeformter, kaminsimsartiger oberer Querbalken vorgesehen ist, unter welchem die Luft aus dem Luftspalt zu einem von der Stellwand beabstandeten Auslaß strömen kann. Auch hier ergibt sich ein gegebenenfalls nicht erwünschtes simsartiges Erscheinungsbild und es lassen sich für die Produktion nur mit großem Aufwand unterschiedliche Ausführungen herstellen, da der Querbalken mit seiner unteren Luftführungsfläche einstückig an die Verkleidung angeformt ist. Darüberhinaus sind bestehende, Wärmeabgabeeinrichtungen nicht mit einem solchen Luftführungskanal nachrüstbar.From FR-A-2 037 643 a heat emission device with a cladding is known, on which an integrally molded, chimney-like upper crossbeam is provided, under which the air can flow from the air gap to an outlet spaced from the partition. Here, too, there may be an undesired cornice-like appearance and it is only possible to produce different versions for production with great effort, since the crossbar with its lower air guiding surface is integrally formed on the cladding. In addition, existing heat emission devices cannot be retrofitted with such an air duct.

Der Erfindung liegt die Aufgabe zugrunde, eine Wärmeabgabeeinrichtung mit einer Luftleiteinrichtung zu entwickeln, welche die Luft an einem von der Wand beabstandeten Ort aus dem Luftspalt herausleitet, und welche hinter ihrer Rückwand eine intensive Luftströmung ermöglicht und Staubfahnen an den Stellwänden vermeidet.The invention has for its object to develop a heat emission device with an air guide device, which guides the air out of the air gap at a location spaced from the wall, and which allows an intensive air flow behind its rear wall and avoids dust plumes on the partitions.

Die Lösung der geschilderten Aufgabe besteht nach der Erfindung in einer Wärmeabgabeeinrichtung nach Patentanspruch 1. Die Wärmeabgabeeinrichtung weist bei ihrer Oberseite einen Luftführungskanal mit einem Einlaß im Luftspaltbereich an der Rückwand und einem Auslaß beabstandet zur Rückwand auf. Dabei ist der Luftführungskanal durch Formgebung oder Strömungsführungsglieder dafür eingerichtet, eine Strömung aus seinem Auslaß von einer gedachten Ebene in der Rückwand der Wärmeabgabeeinrichtung wegzulenken. Die Luftströmung ist dabei so weit von der Stellwand abzulenken, daß an dieser keine Staubfahnen mehr auftreten.According to the invention, the solution to the stated problem consists in a heat emission device according to claim 1. The heat emission device has at its top an air duct with an inlet in the air gap area on the rear wall and an outlet spaced from the rear wall. The air duct is designed by shaping or flow guide members to direct a flow out of its outlet from an imaginary plane in the rear wall of the heat emission device. The air flow is to be deflected so far from the partition that there are no more dust plumes.

Der Luftführungskanal kann den Gerätedeckel der Wärmeabgabeeinrichtung bilden. Er ist als Aufsatzkörper zum Aufsetzen auf der Oberseite der Wärmeabgabeeinrichtung ausgeführt. Der Luftführungskanal kann auch kürzer als die Oberseite der Wärmeabgabeeinrichtung ausgebildet sein. Der Luftführungskanal ist winkelförmig ausgeführt, wobei ein Winkelarm auf die Spaltbreite und der andere Winkelarm auf die Oberseite der Wärmeabgabeeinrichtung abgestimmt ist. Hierbei kann der Winkelarm, der auf die Oberseite der Wärmeabgabeeinrichtung abgestimmt ist, kürzer als die Oberseite ausgebildet sein.The air duct can form the device cover of the heat emission device. It is designed as an attachment body for attachment to the top of the heat emission device. The air duct can also be made shorter than the top of the heat emission device. The air duct is angular, with one angle arm being matched to the gap width and the other angle arm being matched to the top of the heat emission device. Here, the angle arm, which is matched to the top of the heat emission device, can be made shorter than the top.

Die Erfindung soll nun anhand von in der Zeichnung grob schematisch wiedergegebenen Ausführungsbeispielen näher erläutert werden:

  • In FIG 1 ist eine Wärmeabgabeeinrichtung in der Ausführung als Elektrospeicherheizgerät, vor einer Stellwand aufgestellt, in Seitenansicht veranschaulicht.
  • In FIG 2 ist in der Darstellungsweise nach FIG 1 eine Wärmeabgabeeinrichtung mit dem als Aufsatzkörper ausgeführten Luftführungskanal dargestellt.
  • In FIG 3 ist ein anderes Ausführungsbeispiel der Wärmeabgabeeinrichtung mit einem Luftführungskanal als Aufsatzkörper wiedergegeben.
The invention will now be explained in greater detail on the basis of exemplary embodiments shown roughly schematically in the drawing:
  • In Figure 1, a heat emission device is in the execution as an electric storage heater, set up in front of a partition, illustrated in side view.
  • FIG. 2 shows, in the representation according to FIG. 1, a heat emission device with the air duct designed as an attachment body.
  • FIG. 3 shows another embodiment of the heat emission device with an air duct as an attachment body.

Die Wärmeabgabeeinrichtung nach FIG 1 kann als Elektrospeicherheizgerät 1 verstanden werden, das vor einer Stellwand 2 auf einem Gerätefuß 3 aufgestellt ist. Zwischen Elektrospeicherheizgerät 1 und Stellwand 2 ist ein Luftspalt 4 belassen. Die Wärmeabgabeeinrichtung bildet mit ihrer Oberseite 5 einen Luftführungskanal 7 mit einem Einlaß 9 im Luftspaltbereich an der Rückwand 12 und einem Auslaß 10, der beabstandet zur Rückwand ausgebildet ist. Der Luftführungskanal 7 ist im Ausführungsbeispiel nach FIG 1 in den Gerätedeckel 6 integriert.The heat emission device according to FIG. 1 can be understood as an electric storage heater 1, which is placed in front of a partition 2 on a device base 3. An air gap 4 is left between the electric storage heater 1 and the partition 2. The heat emission device forms with its upper side 5 an air duct 7 with an inlet 9 in the air gap area on the rear wall 12 and an outlet 10 which is formed at a distance from the rear wall. The air duct 7 is integrated into the device cover 6 in the exemplary embodiment according to FIG. 1.

Es ist günstig, den Luftführungskanal 7, also die Vorrichtung zum Umlenken der Luft, nicht direkt dicht an die Stellwand anschließen zu lassen, da in der Praxis Stellwände uneben sind. Es ist daher vorteilhaft, zum luftdichten Wandabschluß einen Schaumstoffstreifen 11 zu verwenden. Allgemein eignet sich ein Formstreifen aus elastischem komprimierbarem Material. Der Schaumstoffstreifen 11 kann vorteilhaft an der Rückwand des Luftführungskanals 7 angebracht sein. Er kann selbstklebend bereitgestellt werden und an der Rückseite des Deckels eines Elektrospeicherheizgerätes oder an der Stellwand aufgebracht werden.It is advantageous not to have the air duct 7, that is to say the device for deflecting the air, connected directly to the partition wall, since in practice the partition walls are uneven. It is therefore advantageous to use a foam strip 11 for the airtight closure of the wall. A shaped strip made of elastic, compressible material is generally suitable. The foam strip 11 can advantageously be attached to the rear wall of the air duct 7. It can be provided self-adhesive and applied to the back of the lid of an electric storage heater or to the partition.

Im Ausführungsbeispiel nach FIG 2 ist der Luftführungskanal 7 als Aufsatzkörper zum Aufsetzen auf der Oberseite 5 der Wärmeabgabeeinrichtung ausgeführt. Der Luftführungskanal ist winkelförmig ausgebildet, wobei ein Winkelarm auf die Spaltbreite und der andere Winkelarm auf die Oberseite der Wärmeabgabeeinrichtung abgestimmt ist.In the embodiment shown in FIG 2, the air duct 7 is designed as an attachment body to be placed on the top 5 of the heat emission device. The air duct is angular, with an angle arm on the gap width and the other angle arm is matched to the top of the heat emission device.

Der Winkelarm 8, der auf die Oberseite 5 der Wärmeabgabeeinrichtung abgestimmt ist, kann nach FIG 3 kürzer als die Oberseite 5 der Wärmeabgabeeinrichtung ausgeführt sein.The angle arm 8, which is matched to the top 5 of the heat emission device, can be made shorter than the top 5 of the heat emission device according to FIG. 3.

Der erfindungsgemäße Aufbau der Wärmeabgabeeinrichtung läßt sich auch bei verkleideten Heizkörpern einer Zentralheizung entsprechend vornehmen.The construction of the heat emission device according to the invention can also be carried out correspondingly in the case of covered radiators of a central heating.
