Description
Die vorliegende Erfindung bezieht sich auf einen Raumtemperaturregler für Gebäudeheizund Gebäudekühlsysteme, insbesondere für Flächenheiz- und Flächenkühlsysteme, vorzugsweise für Fußbodenheizungssysteme.The present invention relates to a room temperature controller for building heating and cooling systems, in particular for surface heating and surface cooling systems, preferably for underfloor heating systems.
Derartige Raumtemperaturregler sind im Stand der Technik durch offenkundige Vorbenutzung bekannt. Ausführungsformen derartiger Raumtemperaturregler sind aus einem Gehäuse, dessen Rückseite an einer Wand des Raums anliegend mit dieser verbunden ist, und einer in das Gehäuse aufgenommene Platine, die die elektronischen Komponenten des Raumreglers beinhaltet, aufgebaut. Zur Einstellung des Raumtemperatursollwerts und der Betriebsart des betreffenden Flächenheiz- und/oder Flächenkühlsystems können sich Druckknöpfe oder eine drehbare Einstellungsvorrichtung am Gehäuse befinden. In bekannten Raumreglern kann die dem Raum zugewandte Gehäusewand transparent oder transluzent ausgebildet sein. Die transparente oder transluzente Gehäusewand wird von einer Matrix von Einzellichtquellen auf der Platine von der Rückseite her derart bestrahlt, dass sich aus dem gesamten, von den Einzellichtquellen abgegebenen Licht für den Benutzer relevante Informationen ergeben, beispielsweise zur aktuellen Raumtemperatur, zum eingestellten Raumtemperatursollwert oder zur Betriebsart des betreffenden Flächenheiz- und/oder Flächenkühlsystems. Die bestrahlten Flächen der transparenten oder transluzenten Gehäusewand fungieren dadurch als Anzeigefläche des Raumreglers. Zur Bündelung des von den Einzellichtquellen jeweils abgestrahlten Lichts zur Gehäuseoberfläche hin befinden sich über den Einzellichtquellen kreisrunde Verjüngungen. Die Stromversorgung für derartige Raumtemperaturregler kann einerseits extern über aus der Wand herausgeführte und im Gehäuse des Raumtemperaturreglers klemmend oder durch Verschraubung fixierte Kabel oder anderseits intern durch eine Batterie oder einen Akku erfolgen. Als Einzellichtquellen werden dabei insbesondere LEDs (Light Emitting Diodes, lichemittierende Dioden) eingesetzt.Such room temperature controllers are known in the prior art through obvious prior use. Embodiments of such room temperature controllers are made up of a housing, the back of which is connected to a wall of the room, and a circuit board which is accommodated in the housing and contains the electronic components of the room controller. To adjust the room temperature setpoint and the operating mode of the relevant surface heating and/or surface cooling system, there can be push buttons or a rotatable adjustment device on the housing. In known room controllers, the housing wall facing the room can be transparent or translucent. The transparent or translucent housing wall is irradiated from the back by a matrix of individual light sources on the circuit board in such a way that the entire light emitted by the individual light sources provides relevant information for the user, for example about the current room temperature, the set room temperature setpoint or the operating mode of the relevant surface heating and/or surface cooling system. The irradiated surfaces of the transparent or translucent housing wall thus function as the display area of the room controller. In order to concentrate the light emitted by the individual light sources towards the surface of the housing, there are circular tapers above the individual light sources. The power supply for such room temperature controllers can be provided externally via cables led out of the wall and clamped or screwed into the housing of the room temperature controller, or internally via a battery or accumulator. LEDs (light emitting diodes) are used in particular as individual light sources.
Beispielsweise beschreibt die
Als nachteilig wird an den beschriebenen Raumtemperaturreglern befunden, dass aufgrund der Herstellung der transparenten oder transluzenten Gehäusewand mittels Spritzguss die einzubringenden Verjüngungen dazu führen, dass lediglich ein Abstand zwischen den einzelnen Lichtpunkten von mindestens 2 mm und ein Durchmesser der einzelnen Lichtpunkte von mindestens 1 mm realisiert werden kann. Dies führt zu einer unscharfen Anzeige. Dazu trägt zusätzlich bei, dass das Licht in den Verjüngungen durch das sie umgebende, der transparente oder transluzente Material gestreut wird.The disadvantage of the room temperature controllers described is that due to the production of the transparent or translucent housing wall by injection molding, the tapers to be introduced lead to only a distance between the individual ones Light points of at least 2 mm and a diameter of the individual light points of at least 1 mm can be achieved. This results in a blurry display. This is also helped by the fact that the light in the tapers is scattered by the surrounding transparent or translucent material.
Vor diesem Hintergrund liegt der vorliegenden Erfindung die Aufgabe zugrunde, einen Raumtemperaturregler für Flächenheiz- und/oder Flächenkühlsysteme zur Verfügung zu stellen, der die Nachteile des Stands der Technik überwindet. Insbesondere soll der erfindungsgemäße Raumtemperaturregler über eine schärfere Anzeige verfügen.Against this background, the present invention is based on the object of providing a room temperature controller for surface heating and/or surface cooling systems which overcomes the disadvantages of the prior art. In particular, the room temperature controller according to the invention should have a sharper display.
Diese und andere Aufgaben werden durch einen Raumtemperaturregler mit den Merkmalen des Anspruchs 1 gelöst. Bevorzugte Ausführungsformen des erfindungsgemäßen Raumtemperaturreglers sind in den abhängigen Ansprüchen beschrieben.These and other tasks are solved by a room temperature controller with the features of
Gemäß der vorliegenden Erfindung wurde erkannt, dass der Effekt der Lichtstreuung durch das transparente oder transluzente Material der Gehäusewand dadurch verhindert werden kann, dass das von den Einzellichtquellen emittierte Licht zunächst durch eine Lochmaske geleitet wird, deren Löcher von lichtundurchlässigem Material umgeben sind. Bevorzugt wird dazu eine dünne Maske, bei der es sich insbesondere um ein separates Bauteil handelt, d.h. die Lochmaske ist nicht in das Gehäuse oder die Platine des erfindungsgemäßen Raumtemperaturreglers integriert, direkt auf die Matrix der Einzellichtquellen aufgebracht und fixiert. Die Maske kann mittels Laserschneiden hergestellt werden. Die einzelnen Lichtpunkte sind somit optisch voneinander getrennt werden, weil die Maske das seitliche Streuen des von den Einzellichtquellen emittierte Lichts verhindert. Durch die Maske lässt sich eine Verringerung des Abstands zwischen den einzelnen Lichtpunkten auf bis zu 1,2 mm und des Durchmessers der einzelnen Lichtpunkte auf bis zu 0,5 mm realisieren, woraus eine schärfere Anzeige resultiert.According to the present invention, it was recognized that the effect of light scattering by the transparent or translucent material of the housing wall can be prevented by first guiding the light emitted by the individual light sources through a shadow mask, the holes of which are surrounded by opaque material. For this purpose, a thin mask, which is in particular a separate component, i.e. the shadow mask is not integrated into the housing or the circuit board of the room temperature controller according to the invention, is preferably applied and fixed directly to the matrix of the individual light sources. The mask can be made using laser cutting. The individual light points are thus optically separated from one another because the mask prevents the light emitted from the individual light sources from being scattered laterally. The mask allows the distance between the individual light points to be reduced to up to 1.2 mm and the diameter of the individual light points to up to 0.5 mm, resulting in a sharper display.
Dementsprechend liegt die vorliegende Erfindung in der Bereitstellung eines Raumtemperaturreglers für Flächenheiz- und/oder Flächenkühlsysteme, der ein Gehäuse mit einer transparenten oder transluzenten Anzeigefläche; und eine in dem Gehäuse aufgenommene Platine, auf der eine Matrix von Einzellichtquellen angeordnet ist, die dazu eingerichtet sind, die Anzeigefläche rückseitig zu bestrahlen, wobei zwischen der Matrix von Einzellichtquellen und der Anzeigefläche eine Lochmaske derart angeordnet ist, dadurch gekennzeichnet dass jede Einzellichtquelle der Matrix mindestens einem Loch der Lochmaske zugeordnet ist, wobei zumindest die Löcher der Lochmaske von einem lichtundurchlässigem Material umgeben sind, wobei der Abstand zwischen zwei Einzellichtquellen der Matrix im Bereich von 1,2 mm bis 1,8 mm liegt und jede Einzellichtquelle einen Durchmesser im Bereich von 0,5 mm bis 0,9 mm aufweist.Accordingly, the present invention lies in the provision of a room temperature controller for surface heating and/or surface cooling systems, which has a housing with a transparent or translucent display surface; and a circuit board accommodated in the housing, on which a matrix of individual light sources is arranged, which are designed to irradiate the display surface from the back, a shadow mask being arranged between the matrix of individual light sources and the display surface in such a way, characterized in that each individual light source of the matrix at least is assigned to a hole in the shadow mask, at least the holes in the shadow mask being surrounded by an opaque material, the distance between two individual light sources of the matrix being in the range of 1.2 mm to 1.8 mm and each individual light source having a diameter in the range of 0 .5 mm to 0.9 mm.
Wie hierin verwendet, bezieht sich der Begriff "lichtundurchlässiges Material" im Zusammenhang mit der vorliegenden Erfindung jeweils auf die von der jeweiligen Einzellichtquelle emittierte Strahlung. Dabei emittieren die Einzellichtquellen bevorzugt Licht im sichtbaren Wellenlängenbereich (etwa 380 - 780 nm). Lichtundurchlässigkeit soll dabei - bezogen auf die jeweilige Wellenlänge - einen Transmissionsgrad von vorzugsweise höchstens etwa 10%, bevorzugt höchstens etwa 5% und besonders bevorzugt höchstens etwa 1% bedeuten.As used herein, the term "light opaque material" in the context of the present invention refers to the radiation emitted by the respective individual light source. The individual light sources preferably emit light in the visible wavelength range (approximately 380 - 780 nm). Opaqueness should mean - based on the respective wavelength - a transmittance of preferably at most about 10%, preferably at most about 5% and particularly preferably at most about 1%.
Dabei kann es von Vorteil sein, wenn die Lochmaske vollständig aus lichtundurchlässigem Material hergestellt ist. Dies trägt zur Schärfe der Anzeige bei. Darüber hinaus ist eine Maske vollständig aus lichtundurchlässigem Material leicht herzustellen.It can be advantageous if the shadow mask is made entirely of opaque material. This contributes to the sharpness of the display. In addition, a mask made entirely of opaque material is easy to make.
Es kann sich auch als günstig erweisen, wenn die Lochmaske derart angeordnet ist, dass jede Einzellichtquelle der Matrix genau einem Loch der Lochmaske zugeordnet ist. Auch das trägt zur Schärfe und zur Helligkeit der Anzeige bei. Besonders bevorzugt ist über jeder Einzellichtquelle der Matrix ein Loch der Lochmaske angeordnet.It can also prove to be advantageous if the shadow mask is arranged in such a way that each individual light source in the matrix is assigned to exactly one hole in the shadow mask. This also contributes to the sharpness and brightness of the display. A hole in the shadow mask is particularly preferably arranged above each individual light source in the matrix.
Ebenso kann es von Nutzen sein, wenn die Lochmaske direkt auf die Matrix aufgebracht, vorzugsweise aufgeklebt ist. Durch direktes Aufbringen der Maske auf die Matrix lassen sich die Schärfe und zur Helligkeit der Anzeige weiter verbessern.It can also be useful if the shadow mask is applied directly to the matrix, preferably glued on. By applying the mask directly to the matrix, the sharpness and brightness of the display can be further improved.
Es kann auch hilfreich sein, wenn der Abstand zwischen zwei Einzellichtquellen der Matrix im Bereich von 1,4 mm bis 1,6 mm liegt, bevorzugt etwa 1,5 mm beträgt. Durch den erfindungsgemäßen Einsatz der Maske lassen sich solche Abstände zwischen zwei Einzellichtquellen der Matrix bei gängigen Herstellungsverfahren der Komponenten erzielen.It can also be helpful if the distance between two individual light sources of the matrix is in the range of 1.4 mm to 1.6 mm, preferably about 1.5 mm. By using the mask according to the invention, such distances between two individual light sources of the matrix can be achieved using common manufacturing processes for the components.
Es kann sich auch als günstig erweisen, wenn jede Einzellichtquelle einen Durchmesser im Bereich von 0,6 mm bis 0,8 mm, bevorzugt etwa 0,7 mm aufweist. Durch den erfindungsgemäßen Einsatz der Maske lassen sich Einzellichtquellen mit derart kleinem Durchmesser bei gängigen Herstellungsverfahren der Komponenten einsetzen.It can also prove to be advantageous if each individual light source has a diameter in the range of 0.6 mm to 0.8 mm, preferably about 0.7 mm. By using the mask according to the invention, individual light sources with such a small diameter can be used in common manufacturing processes for the components.
Darüber hinaus kann es von Nutzen sein, wenn die Einzellichtquellen als einzelne LEDs ausgebildet sind. LEDs stellen kostengünstige, leicht zugängliche Einzellichtquellen mit geringem Energieverbrauch dar.In addition, it can be useful if the individual light sources are designed as individual LEDs. LEDs represent cost-effective, easily accessible individual light sources with low energy consumption.
Ebenso kann es von Vorteil sein, wenn der Raumtemperaturregler weiter mindestens ein Bedienelement umfasst. Ein solches Bedienelement kann zur Einstellung des Raumtemperatursollwerts und der Betriebsart des mit dem erfindungsgemäßen Raumtemperaturregler zu regelnden Flächenheiz- und/oder Flächenkühlsystems eingesetzt werden. Bei den Bedienelement kann es sich beispielsweise um Druckknöpfe und/oder drehbare Einstellungsvorrichtungen handeln, die bevorzugt am Gehäuse, insbesondere in der die Anzeigefläche enthaltende Gehäusewand, angeordnet sind.It can also be advantageous if the room temperature controller also includes at least one control element. Such a control element can be used to set the room temperature setpoint and the operating mode of the surface heating and/or surface cooling system to be controlled with the room temperature controller according to the invention. The operating elements can be, for example, push buttons and/or rotatable adjustment devices, which are preferably arranged on the housing, in particular in the housing wall containing the display area.
Die Dicke der Maske liegt vorzugsweise im Bereich von 0,3 mm bis 0,8 mm, besonders bevorzugt im Bereich von 0,4 mm bis 0,6 mm. Eine Dicke der Maske von etwa 0,5 mm ist erfindungsgemäß besonders vorteilhaft.The thickness of the mask is preferably in the range from 0.3 mm to 0.8 mm, particularly preferably in the range from 0.4 mm to 0.6 mm. A mask thickness of approximately 0.5 mm is particularly advantageous according to the invention.
Der erfindungsgemäße Raumtemperaturregler sowie einzelne Teile davon können beispielsweise zeilenweise oder schichtweise unter Verwendung eines zeilenaufbauenden oder schichtaufbauenden Fertigungsverfahrens (z. B. 3D-Druck) hergestellt werden.The room temperature controller according to the invention and individual parts thereof can be produced, for example, line by line or layer by layer using a line-building or layer-building manufacturing process (e.g. 3D printing).
