Abstract
Es wird ein Heizgerät vorgeschlagen mit einem Gasbrenner (10), einer Brennkammer (11), einem Wärmeübertrager (14) und einem zum Aufstellungsraum des Heizgerätes hin geschlossenen Luftkasten (20). Der Luftkasten (20) weist mindestens ein Überdruckventil (40) auf, über das ein im Inneren des Luftkastens (20) entstehender Überdruck nach außen ableitbar ist.It becomes a heater proposed with a gas burner (10), a combustion chamber (11), a Heat exchanger (14) and a closed to the installation space of the heater air box (20). The air box (20) has at least one pressure relief valve (40) over which a resulting in the interior of the air box (20) overpressure outward is derivable.
Description
Die Erfindung betrifft ein Heizgerät nach dem Oberbegriff des Anspruchs 1.The The invention relates to a heater according to the preamble of claim 1.
Bei
den sogenannten Außenwandheizgeräten, die

Aufgabe der vorliegenden Erfindung ist es, störende Schwingungen des Luftkastens zu unterbinden.task It is the object of the present invention to eliminate disturbing vibrations of the air box to prevent.
Vorteile der ErfindungAdvantages of invention
Durch das erfindungsgemäße Heizgerät mit den kennzeichnenden Maßnahmen des Anspruchs 1 werden Druckschwankungen durch den Abbau des im Luftkasten entstehenden Überdrucks vermieden. Dadurch kommt es nicht mehr zu einem Pulsieren der Wand des Luftkastens, wodurch die vom Luftkasten ausgehenden Schwingungen und damit die dadurch verursachten störenden Geräusche vermieden werden.By the heater according to the invention with the characterizing measures of claim 1, pressure fluctuations due to the degradation of the Air box resulting overpressure avoided. As a result, there is no longer a pulsation of the wall of the air box, whereby the vibrations emanating from the air box and thus the disturbing noises caused thereby are avoided.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen der Erfindung möglich. Besonders zweckmäßig ist es, das Überdruckventil in der Nähe des Brenners in der Wand des Luftkastens anzuordnen, wobei eine bevorzugte Stelle der Boden des Luftkastens ist. Mittels eines weiteren Ventils, das bei einem Unterdruck im Inneren des Luftkastens Umgebungsluft in den Luftkasten einleitet, kann das Entstehen einer pulsierenden Schwingung besonders wirksam verhindert werden. Zwecks Normeinhaltung ist vorgesehen, dass das Überdruckventil bei einem Innendruck im Luftkasten von ≥ 1 mbar öffnet.By in the subclaims listed activities Advantageous developments of the invention are possible. Especially is appropriate it, the pressure relief valve near to arrange the burner in the wall of the air box, wherein a preferred Place the bottom of the air box is. By means of another valve, at a negative pressure inside the air box ambient air In the air box, the emergence of a pulsating Vibration can be prevented particularly effectively. For the purpose of compliance is provided that the pressure relief valve at an internal pressure in the air box of ≥ 1 mbar opens.
