Abstract

A showcase for storing and/or displaying objects which require a protective gas atmosphere, the base and the cover construction of the showcase more or less surrounding the showcase interior which is sealed in an airtight manner as far as possible relative to the exterior air, having a compressor (2) by which the air (1) present outwith the showcase interior (7) is suctioned in and compressed. Subsequently a protective gas is produced from the compressed air by a gas producer (3) and is supplied to the showcase interior (7), the gas producer (3) being able to be accommodated within or outwith the showcase. In this way, provision of a supply container for the protective gas is avoided.

Description

Vitrine zur Aufbewahrung und/oder Zurschaustellung von Gegenständen Showcase for the storage and / or display of objects
Die Erfindung betrifft eine Vitrine zur Aufbewahrung und/oder Zurschaustellung von Gegenständen, deren Boden und deren Deckelkonstruktion den Vitrineninnenraum mehr oder weniger umschließen, welcher gegenüber der Außenluft so weit wie möglich luftdicht abgeschlossen ist.The invention relates to a display case for storing and / or displaying objects, the bottom and the lid construction of which more or less enclose the display case interior, which is sealed airtight as far as possible from the outside air.
Ein derartige Vitrine ist bereits bekannt. So wird in der ÖE-PS 39 05 212 C2 eine Vitrine zur Aufbewahrung und/oder Zurschaustellung von Gegenständen beschrieben, bei welcher zum Schutz der Ausstellungsgegenstände die umgebende Luft im Innenraum der Vitrine nicht nur staubfrei sondern auch noch im Rahmen einer gewünschten Luftfeuchtigkeit gehalten wird. Außer der Staubfreiheit, der Luftfeuchtigkeit, usw. kann nun auch der Fall eintreten, daß neben den genannten Anforderungen bestimmte Gegenstände im Innenraum der Vitrine eine neutrale Umgebung benötigen. Deshalb ist es auch, möglich, den Innenraum mit einem neutralen Gas zu füllen, wenn dies der Schutz der ausgestellten Gegenstände es erfordert. In diesem Zusammenhang ist es bereits bekannt, hierzu ein Gas zu verwenden, das in einem Vorratsbehälter bereitgehalten wird.Such a display case is already known. For example, the ÖE-PS 39 05 212 C2 describes a showcase for the storage and / or display of objects, in which the surrounding air in the interior of the showcase is not only dust-free but also kept within the desired humidity to protect the exhibits. In addition to the absence of dust, the humidity, etc., the case may now arise that, in addition to the requirements mentioned, certain objects in the interior of the display case require a neutral environment. Therefore it is also possible to fill the interior with a neutral gas if the protection of the exhibited objects requires it. In this connection, it is already known to use a gas for this purpose, which is kept ready in a storage container.
Ein derartiger Vorratsbehälter hat den Nachteil, daß dieser' ständig auf seinen Füllstand überwacht werden muß. Die Aufgabe der Erfindung besteht nun darin, eine Vitrine anzugeben, deren Innenraum ein Gas enthält, wobei sichergestellt ist, daß eine besondere Überwachung des Gasvorrats vermieden wird.Such a storage container has the disadvantage that it ' must be constantly monitored for its fill level. The object of the invention is to provide a display case, the interior of which contains a gas, ensuring that special monitoring of the gas supply is avoided.
Diese Aufgabe wird dadurch gelöst, daß ein Kompressor vorgesehen ist, durch welchen die außerhalb des Vitrineninnenraums vorhandene Luft angesaugt und verdichtet wird und daß aus der verdichteten Luft durch einen Gaserzeuger ein Schutzgas erzeugt wird, welches dem Vitrineninnenraum zugeführt wird, wobei der Gaserzeuger innerhalb oder außerhalb der Vitrine untergebracht ist.This object is achieved in that a compressor is provided, through which the air present outside the interior of the showcase is sucked in and compressed, and that a protective gas is generated from the compressed air by a gas generator, which gas is supplied to the interior of the showcase, the gas generator being inside or outside the showcase is housed.
Durch die Erzeugung des Schutzgases vor Ort kann auf einen Vorratsbehälter für das Schutzgas verzichtet werden. Je nach Ausführung kann nun der Kompressor und der Gaserzeuger einen Bestandteil der Vitrine darstellen, es ist jedoch auch möglich,, außerhalb der Vitrine einen Kompressor und einen Gaserzeuger- entweder für eine Vitrine oder auch für jeweils mehrere Vitrinen vorzusehen.By generating the shielding gas on site, a reservoir for the shielding gas can be dispensed with. Depending on the version, the compressor and the gas generator can now be part of the display case, but it is also possible to provide a compressor and a gas generator outside the display case - either for one display case or for several display cases.
Eine weitere Ausbildung der Erfindung besteht darin, daß das Schutzgas vor ■ einer. Einleitung in den Vitrineninnenraum einer Befeuchtungsvorrichtung zugerunrt w rd, wird Im Vitrineninnenraum zusätzlich zu der Schutzgasatmosphäre ein besonderes Raumklima benötigt, dann kann mit Hilfe der Befeuchtungseinrichtung die Feuchte des Schutzgases eingestellt und/oder reguliert werden.Another embodiment of the invention is that the protective gas before ■ one. Introduction into the showcase interior of a humidifier If a special indoor climate is required in addition to the protective gas atmosphere in the showcase interior, the humidity of the protective gas can then be adjusted and / or regulated with the help of the humidification device.
Dies ist besonders vorteilhaft in Verbindung mit einer Kühlvorrichtung, wobei diese mit der Befeuchtungsvorrichtung zusammen arbeitet.This is particularly advantageous in connection with a cooling device, which works together with the moistening device.
Weitere Vorteile ergeben sich aus den ünteransprüchen.Further advantages result from the subordinate claims.
Die Erfindung wird anhand eines Ausführungsbeispiels näher- erläutert, welches in der Zeichnung dargestellt ist.The invention is explained in more detail using an exemplary embodiment which is shown in the drawing.
Die Zuluft 1 aus der Umgebung der Vitrine wird von einem Kompressor 2 angesaugt und komprimiert, beispielsweise auf einen Wert von 6 bis 8 bar. Diese Luft wird einem Gaserzeuger 3 zugeführt, welcher mit Hilfe einer Anordnung von Membranen Stickstoffgas aus der Luft ausscheidet. Die nicht benötigten Restbestandteile der Luft, die bei dem Vorgang entstehen, werden der Umgebung der Vitrine zugeführt. Ein derartiger Gaserzeuger besteht aus einer Anordnung von Membranen, die in einem geschlossenen Gehäuse untergebracht sind, wobei an dessen Eingang Luft zugeführt und an einem Ausgang Stickstoffgas abgenommen werden kann. Sein Aufbau ist in der EP-OS 0 298 531 AI beschrieben (gas Separation apparatus and also method for Separation gases by means of such apparatus), weshalb auf die Struktur der Menbranen und deren Wirkungsweise im Rahmen dieser Beschreibung nicht weiter eingegangen wird. Der Beschreibung der genannten Druckschrift läßt sich entnehmen, daß die Luft mit einem höheren Druck in das Gehäuse gepreßt werden muß.The supply air 1 from the surroundings of the showcase is drawn in and compressed by a compressor 2, for example to a value of 6 to 8 bar. This air is fed to a gas generator 3, which uses an arrangement of membranes to separate nitrogen gas from the air. The unnecessary residual components of the air, which arise during the process, are fed into the surroundings of the showcase. Such a gas generator consists of an arrangement of membranes which are accommodated in a closed housing, air being supplied at the inlet and nitrogen gas being able to be taken off at the outlet. Its structure is described in EP-OS 0 298 531 AI (gas separation apparatus and also method for separation gases by means of such apparatus), which is why the structure of the membranes and their mode of operation will not be discussed further in this description. The description of the cited document shows that the air must be pressed into the housing at a higher pressure.
Das Stickstoffgas, welches einen hohen Druck aufweist, wird durch ein Druckreduzierventil 4 auf einen Wert vermindert, welcher einem geringen Überdruck gegenüber dem Luftdruck außerhalb der Vitrine entspricht. Das Stickstoffgas, das nur noch eine relative Feuchtigkeit von 0 — 6% aufweist, kann nun in den Innenraum 7 der Vitrine geleitet werden. Durch den geringen Überdruck des Stickstoffgases im Innenraum der Vitrine gegenüber der Außenluft wird sich nun auch nach einem öffnen der Vitrine im Lauf mehrerer Stunden eine reine Stickstoffatmosphäre einstellen, da eine Vitrine der eingangs erwähnten Art nie vollständig gegenüber der Außenluft abgedichtet ist.The nitrogen gas, which has a high pressure, is reduced by a pressure reducing valve 4 to a value which corresponds to a slight excess pressure compared to the air pressure outside the showcase. The nitrogen gas, which only has a relative humidity of 0-6%, can now be passed into the interior 7 of the display case. Due to the slight overpressure of the nitrogen gas in the interior of the showcase compared to the outside air, a pure nitrogen atmosphere will also develop after several hours after opening the showcase, since a showcase of the type mentioned at the outset is never completely sealed against the outside air.
Wird nun im Innenraum 7 der Vitrine zusätzlich ein besonderes Raumklima gewünscht, d.h. zusätzlich eine bestimmte Temperatur und eine vorgegebene t'eucntig eit des Schutzgases gewünscht, dann muß das am Ausgang des Druckreduzierventils 4 austretende Stickstoffgas zunächst einer Befeuchtungsvorrichtung 5 zugeführt werden, durch welche dieses mit Feuchtigkeit entsprechend angereichert wird. Die Befeuchtungsvorrichtung 5 kann beispielsweise derart wirken, daß das Stickstoffgas über eine Wasseroberfläche geleitet wird und auf diese Weise Feuchtigkeit aufnimmt. Durch eine anschließende Kühlung des feuchten Schutzgases mit Hilfe einer Kühlvorrichtung 6 wird dann dessen Feuchtigkeit und Temperatur eingestellt und geregelt, dabei wird die Luftfeuchtigkeit auf einen vorgegebenen Wert gebracht, beispielsweise 35 bis 65%. Da bei der Komprimierung der Kondenswasser enthaltenden Zuluft im Kompressor 2 infolge der Luftfeuchtigkeit Wasser entsteht, kann dieses gesammelt und zur Ergänzung des Wasservorrats der Befeuchtungsvorrichtung 5 vorteilhaft verwendet werden.If a special indoor climate is now also desired in the interior 7 of the showcase, ie in addition a certain temperature and a predetermined one t'eucntig eit of the protective gas, then the nitrogen gas emerging at the outlet of the pressure reducing valve 4 must first be fed to a humidification device 5, through which this is appropriately enriched with moisture. The moistening device 5 can act, for example, in such a way that the nitrogen gas is passed over a water surface and in this way absorbs moisture. Subsequent cooling of the moist protective gas with the aid of a cooling device 6 then sets and regulates its moisture and temperature, the air humidity being brought to a predetermined value, for example 35 to 65%. Since water is produced in the compressor 2 as a result of the air humidity when the supply air containing condensation is compressed, this can be collected and advantageously used to supplement the water supply of the humidification device 5.
Im Innenraum 7 der Vitrine ist ein Temperatursensor 9 und ein Drucksensor 10 angebracht, beide Sensoren sind mit einer elektronischen Steuereinrichtung 8 elektrisch verbunden. Mit Hilfe der Steuereinrichtung 8 wird die Temperatur der Kühlvorrichtung 6 in Abhängigkeit der Meßwerte des Temperatursensors 9 und damit die Temperatur und die Feuchtigkeit des Stickstoffgases im Innenraum der Vitrine 7 auf vorgegebene Werte eingestellt bzw. geregelt. Das Druckreduzierventil 4 kann nun manuell auf einen bestimmten Wert fest eingestellt sein. Es ist jedoch auch denkbar, daß das Druckreduzierventil 4 in Abhängigkeit von den Meßwerten des Drucksensors -10 von der Steuereinrichtung 8 einstellbar ist. Damit kann der Überdruck im Innenraum 7 der Vitrine beispielsweise nach dem Öffnen und Schließen der Vitrine für einen vorgegebenen Zeitraum etwas erhöht werden, um zu erreichen, daß sich der Innenraum 7 der Vitrine schneller wieder mit dem Stickstoffgas füllt, indem die eingedrungene Luft infolge der Undichtigkeiten hinaus gedrängt wird. Die Steuerinrichtung 8 kann in diesem Fall zusätzlich mit einem nicht gezeigten Türschalter oder Gasdichtesensor elektrisch verbunden sein.A temperature sensor 9 and a pressure sensor 10 are mounted in the interior 7 of the display case, both sensors being electrically connected to an electronic control device 8. With the help of the control device 8, the temperature of the cooling device 6 is set or regulated as a function of the measured values of the temperature sensor 9 and thus the temperature and the humidity of the nitrogen gas in the interior of the display case 7 to predetermined values. The pressure reducing valve 4 can now be set manually to a certain value. However, it is also conceivable that the pressure reducing valve 4 can be set by the control device 8 as a function of the measured values of the pressure sensor -10. Thus, the overpressure in the interior 7 of the showcase, for example after opening and closing the showcase, can be increased somewhat for a predetermined period of time in order to ensure that the interior 7 of the showcase fills up again more quickly with the nitrogen gas by the air which has entered as a result of the leaks is pushed out. In this case, the control device 8 can additionally be electrically connected to a door switch or gas density sensor, not shown.
Der Kompressor 2 und der Gaserzeuger 3 können nun in der Vitrine selbst und zwar zweckmäßigerweise in deren Unterteil untergebracht sein. Es ist jedoch auch denkbar, statt dessen die beiden genannten Einrichtungen außerhalb der Vitrine anzuordnen. Weiterhin ist es möglich, einen gemeinsamen Kompressor 2 und Gaserzeuger 3 für jeweils mehrere Vitrinen vorzusehen, wobei dann das erzeugte Stickstoffgas den einzelnen Vitrinen über Schlauchleitungen zugeführt wird. The compressor 2 and the gas generator 3 can now be accommodated in the display case itself, expediently in the lower part thereof. However, it is also conceivable to arrange the two devices mentioned outside the display case instead. Furthermore, it is possible to provide a common compressor 2 and gas generator 3 for each of several showcases, in which case the nitrogen gas generated is fed to the individual showcases via hose lines.
