Description

Die Erfindung bezieht sich auf ein Dichtprofil eines mit Schaum ausgespritzten Gehäuses, wobei zu dämmende Gegenstände zum Teil im Gehäuse platziert sind und der Raum zwischen dem Gehäuse und dem zu dämmende Gegenstand mit einem Schaum ausgespritzt ist.The invention relates to a sealing profile of a sprayed with foam housing, with objects to be insulated are placed in part in the housing and the space between the housing and the object to be insulated is sprayed with a foam.

Zu dämmende Gegenstände werden zum Teil in Gehäuse platziert und anschließend der Raum zwischen dem Gehäuse und dem zu dämmenden Gegenstand mit einem Schaum ausgespritzt. Hierbei ist darauf zu achten, dass kein Schaum zwischen den Fugen der Gehäuseteile austritt.Objects to be insulated are partly placed in the housing and then the space between the housing and the object to be insulated is sprayed with a foam. It is important to ensure that no foam escapes between the joints of the housing parts.

Bei ausgeschäumten Gehäusen gemäß dem Stand der Technik werden daher entweder die Fugen mittels Klebestreifen abgedichtet oder eine Folie zwischen das Gehäuse und den Schaum platziert. Die erstgenannte Lösung hat den Nachteil, dass sie zeitaufwendig und somit teuer ist. Die zweite Lösung hat den Nachteil, dass bei Falten in der Folie Hohlräume entstehen und auch keine stabilisierende Wirkung durch den Schaum entsteht, da die Folie lediglich an dem Gehäuse anliegt, nicht jedoch mit der Wand verklebt.In the case of foam-filled housings according to the prior art, therefore, either the joints are sealed by means of adhesive strips or a film is placed between the housing and the foam. The former solution has the disadvantage that it is time consuming and thus expensive. The second solution has the disadvantage that when folded in the film voids and no stabilizing effect caused by the foam, since the film is applied only to the housing, but not glued to the wall.

Aus der EP 797 055 A1 ist ein Wasserheizer mit einem ausgeschäumten Gehäuse bekannt. Deckel und Zylinder sind mittels Umbördelungen miteinander verbunden. Diese Art der Verbindung dichtet zwar den Übergang gegen Schaumaustritt ab, doch kann die Blechverformung erst bei der Montage des Wasserheizers erfolgen.From the EP 797 055 A1 is a water heater with a foam-filled housing known. Lid and cylinder are connected by means of beadings. Although this type of connection seals the transition against foam leakage, but the sheet deformation can be done only during installation of the water heater.

Ziel der Erfindung ist es, die Nachteile des Standes der Technik zu vermeiden und ein gedämmtes Gehäuse zu schaffen, welches mit einfachem Arbeitsaufwand mit Schaum gefüllt werden kann, bei dem kein Schaum durch Fugen austritt und das zugleich einen steifen Aufbau besitzt.The aim of the invention is to avoid the disadvantages of the prior art and to provide an insulated housing, which can be filled with a simple workload with foam in which no foam leaks through joints and at the same time has a rigid structure.

Erfindungsgemäß wird dies durch ein Dichtprofil für Gehäuse gemäß dem unabhängigen Anspruch 1 dadurch erreicht, dass Gehäuseteile mit Hintergreifungen verbunden werden und anschließend das Gehäuse mit Schaum ausgespritzt wird. Die Hintergreifungen sind als Teilbereiche mit elastisch ineinander greifenden Federn ausgestaltet, wobei die Federn über mindestens einer gemeinsamen ersten Stützfläche sowie jeweils einer dieser Stützfläche gegenüberliegenden Abwinklung verfügen. Die beiden Abwinklungen verlaufen, zumindest sofern sie nicht im Eingriff sind, nicht parallel und berühren einander im Eingriff unter Spannung. Die Hintergreifungen verhindern ein Austreten des Schaums durch die Fugen. Da der Schaum mit den Gehäuseteilen beim Aushärten verklebt, wird das Gehäuse auf diese Art zusätzlich versteift. Durch die Spannung besteht zwischen den Gehäuseteilen eine feste Verbindung. Es ergibt sich der Vorteil, dass die Teilbereiche über eine besonders verschiebsichere Fixierung verfügen.This is achieved by a sealing profile for housing according to the independent claim 1, characterized in that housing parts are connected with Hintergreifungen and then the housing is sprayed with foam. The Hintergreifungen are designed as partial areas with elastically interlocking springs, wherein the springs have at least one common first support surface and each one of these support surface opposite angling. The two bends, at least if they are not in engagement, are not parallel and engage each other under tension. The rear grips prevent leakage of the foam through the joints. Since the foam adheres to the housing parts during curing, the housing is additionally stiffened in this way. The voltage between the housing parts a firm connection. This results in the advantage that the subregions have a particularly non-displaceable fixation.

Gemäß den Merkmalen des Anspruchs 2 kann die innere Feder leicht in die äußere Feder eingeführt werden.According to the features of claim 2, the inner spring can be easily inserted into the outer spring.

Durch die Merkmale des Anspruchs 3 wird ein besonders vorteilhafter Einsatz eines erfindungsgemäßen Dichtprofils beschrieben.Due to the features of claim 3, a particularly advantageous use of a sealing profile according to the invention is described.

Die Erfindung wird nun anhand der Zeichnungen näher erläutert. Dabei zeigt

  • Fig. 1 ein Gehäuse ohne Darstellung der erfindungsgemäßen Dichtprofile und ohne Schaum als Explosionszeichnung,
  • Fig. 2 das selbe Gehäuse geschlossen mit Schaum sowie
  • Fig. 3 ein Dichtprofil sowie
  • Fig. 4 bis 5 Details von Varianten eines erfindungsgemäßen Dichtprofils.
The invention will now be explained in more detail with reference to the drawings. It shows
  • Fig. 1 a housing without representation of the sealing profiles according to the invention and without foam as exploded view,
  • Fig. 2 the same housing closed with foam as well
  • Fig. 3 a sealing profile as well
  • 4 to 5 Details of variants of a sealing profile according to the invention.

Fig. 1 zeigt einen Warmwasserspeicher 5 in einem Gehäuse 4, das über mindestens zwei Gehäuseteile 1, 2 verfügt. Während in Fig. 1 das Gehäuse 4 offen und ohne Schaum ist, ist in Fig. 2 das selbe Gehäuse 4 geschlossen mit Schaum 3 zu sehen. Zwischen dem Warmwasserspeicher 5 und den Gehäuseteilen 1, 2 befindet sich ein wärmedämmender Schaum 3, welcher zusätzlich zur wärmedämmenden Funktion auch dem Gehäuse 4 und den darin befindlichen Teilen Stabilität gibt. Fig. 1 shows a hot water tank 5 in a housing 4, which has at least two housing parts 1, 2. While in Fig. 1 the housing 4 is open and without foam is in Fig. 2 to see the same housing 4 closed with foam 3. Between the hot water tank 5 and the housing parts 1, 2 is a heat-insulating foam 3, which in addition to the heat-insulating function and the housing 4 and the parts therein is stability.

Erfindungsgemäß greifen die beiden Gehäuseteile 1, 2 entsprechend der Figuren Fig. 4 bis Fig. 5 in Teilbereichen 11, 21 hintergreifend ineinander ein. Die beiden Gehäuseteile 1, 2 werden derart zusammengefügt, dass die Lücke zwischen dem Gehäuseteil 1 von dem Gehäuseteil 2 geschlossen wird.According to the invention, the two housing parts 1, 2 engage according to the figures Fig. 4 to Fig. 5 in sub-areas 11, 21 engaging behind each other. The two housing parts 1, 2 are joined together such that the gap between the housing part 1 is closed by the housing part 2.

In Fig. 3 ist ein nicht beanspruchtes Dichtprofil zu sehen. Das Gehäuseteil 1 verfügt über eine Sicke 7 kurz vor einer Abschlußkante 9. Das Gehäuseteil 2 verfügt ebenfalls über eine Sicke 7 kurz vor einer Abschlußumkantung 8. Die beiden Gehäuseteile 1, 2 sind derart zusammengefügt, dass die Abschlußkante 9 des Gehäuseteils 1 linienförmig an die Sicke 7 des Gehäuseteils 2 anstößt. Gleichzeitig hintergreift die Abschlußumkantung 8 des Gehäuseteils 2 linienförmig in die Sicke 7 des Gehäuseteils 1. Nieten 6 halten die Gehäuseteile 1, 2 zusammen. Die Abschlußumkantung 8 und die Abschlußkante 9 verformen sich dabei elastisch und sorgen für eine Druckspannung im Berührungsbereich.In Fig. 3 is an unclaimed sealing profile to see. The housing part 1 has a bead 7 just before a final edge 9. The housing part 2 also has a bead 7 just before a Abschlußumkantung 8. The two housing parts 1, 2 are joined together so that the terminal edge 9 of the housing part 1 linearly to the bead 7 of the housing part 2 abuts. At the same time, the end edge 8 of the housing part 2 engages linearly into the bead 7 of the housing part 1. Rivets 6 hold the housing parts 1, 2 together. The Abschlußumkantung 8 and the end edge 9 deform elastically and provide a compressive stress in the contact area.

Innerhalb des Gehäuses 4 befindet sich Dämmschaum 3. Durch die Linienberührung zwischen den beiden Gehäuseteilen 1, 2 kann kein Schaum 3 in die Umgebung entweichen. Minimale Mengen Schaum 3, welche beim Schäumen an der Abschlußkante 9 vorbeistreichen könnten, werden zwischen den Teilbereiche 11, 12 abgefangen und können nicht über die Abschlußumkantung 8 nach außen gelangen.Within the housing 4 is insulating foam 3. Due to the line contact between the two housing parts 1, 2 no foam 3 can escape into the environment. Minimal amounts of foam 3, which could pass by at the end edge 9 during foaming, are trapped between the subregions 11, 12 and can not escape via the end edge 8.

Fig. 4 zeigt ein Dichtprofil, das ohne gesonderte Verbindungsmittel auskommt. Die Gehäuseteile 1, 2 sind derart aufeinander abgestimmt, dass sie elastisch federnd ineinander eingreifen. Die beiden Teilbereiche 11, 21 sind als Federn ausgestaltet, die über zueinander senkrechte Stützflächen 10, 12, an denen die Gehäuseteile 1, 2 aneinander anliegen, verfügen. Zusätzlich verfügt das Gehäuseteil 1 über eine Abwinklung 13 sowie das Gehäuseteil 2 über eine Abwinklung 14. Die Abwinklung 14 greift in die Abwinklung 13 ein, wobei der Winkel zwischen der Stützfläche 12 und der Abwinklung 14 kleiner ist als der Winkel zwischen der Stützfläche 12 und der Abwinklung 13. Hierdurch entsteht Formschluß durch die Stützflächen 10 und 12 sowie die Linienberührung zwischen den Abwinklungen 13 und 14. Durch die elastische Verformung der Gehäuseteile 1, 2 entsteht ferner Kraftschluss. Durch den Form- und Kraftschluss kann kein Schaum 3 aus dem Inneren des Gehäuses 4 nach außen gelangen. Für die Montage wird auf der einen Seite die Abwinkelung 14 des Gehäuseteils 2 (winkelig zur Darstellung in Fig. 3) in die Abwinkelung 13 des Gehäusteils 1 eingeführt und anschließend durch Drehen in die Position gemäß Figur 3 gebracht. Auf der anderen Seite erleichert eine Einrasthilfe 15 die elastische Verformung des Gehäuseteils 1, damit das Gehäuseteil 2 eingeführt werden kann. Fig. 4 shows a sealing profile, which manages without separate connection means. The housing parts 1, 2 are matched to one another such that they engage elastically resiliently in one another. The two subregions 11, 21 are configured as springs, which have mutually perpendicular support surfaces 10, 12, on which the housing parts 1, 2 abut each other. In addition, the housing part 1 has an angled portion 13 and the housing part 2 via a bend 14. The bend 14 engages the bend 13, wherein the angle between the support surface 12 and the bend 14 is smaller than the angle between the support surface 12 and the Angling 13. This results in positive engagement by the support surfaces 10 and 12 and the line contact between the bends 13 and 14. The elastic deformation of the housing parts 1, 2 also creates adhesion. Due to the positive and frictional connection no foam 3 can pass from the interior of the housing 4 to the outside. For mounting on one side, the bend 14 of the housing part 2 (at an angle to the representation in Fig. 3 ) introduced into the bend 13 of the housing part 1 and then by turning in the position according to FIG. 3 brought. On the other hand, a snap-in aid 15 facilitates the elastic deformation of the housing part 1, so that the housing part 2 can be inserted.

Das Fertigungsverfahren sieht vor, dass vorwiegend Schäume auf Basis einer Polyol-Mischung (Hartschaumsystem) verwendet werden. Die Gehäuseteile 1, 2 werden zusammengesetzt, so dass sie über dichte Fugen (wie oben beschrieben) verfügen. Mit sehr kurzen sogenannten Schußzeiten (ca. 2-3sec.) wird das Schaumgemisch in die Form (Raum zwischen Gehäuse 4 und Warmwasserspeicher 5) durch Spritzen aus einer Düse eingebracht: Das Gemisch fängt sofort nach Verlassen der Düse an zu treiben bis der Raum völlig ausgefüllt ist. Hierbei wird das Gehäuse drucksicher in der Schaumform gehalten, so dass auch bei entstehenden Überdrücken die gewollten Mehrmengen an Hartschaumgemisch sicher verbracht werden können. Durch die Menge und den Druck läßt sich die Dichte des Schaums beeinflussen.The production process envisages that primarily foams based on a polyol mixture (hard foam system) are used. The housing parts 1, 2 are assembled so that they have tight joints (as described above). With very short so-called shot times (about 2-3 sec.), The foam mixture in the mold (space between the housing 4 and hot water tank 5) by spraying from a nozzle introduced: The mixture begins immediately after leaving the nozzle to drive until the room is completely filled. In this case, the housing is held pressure-proof in the foam mold, so that even with resulting overpressures the desired excess amounts of hard foam mixture can be safely spent. The amount and the pressure can influence the density of the foam.

Bis das Schaumgemisch in der Reaktionsheftigkeit abnimmt und auszuhärten beginnt, vergeht etwa eine halbe Stunde.It takes about half an hour for the foam mixture to decrease in the reaction strength and harden.

Man unterscheidet zwischen offenzelligem und geschlossenzelligem Schaum. Die Zellstruktur des offenzelliger Schaum bricht nach dem Aushärten partiell auf und entläßt das Treibgas. Hier dringt anstelle des Treibgases die Umgebungsatmosphäre in die Zelle. Offenzelliger Schaum ist besonders geeignet bezüglich Recycling, weist eine geringe Dichte auf, hat jedoch keine hohe Stabilität, so dass offenzelliger Schaum nur bedingt als tragendes Material eingesetzt werden kann.One distinguishes between open-cell and closed-cell foam. The cell structure of the open-cell foam breaks after curing partially and releases the propellant gas. Here, instead of the propellant gas, the ambient atmosphere penetrates into the cell. Open-celled foam is particularly suitable for recycling, has a low density, but has no high stability, so that open-cell foam can be used only partially as a supporting material.

Der gesamte Schäumprozeß muss - um reproduzierbar gesteuert werden zu können - in allen Parametern (Zeiten, Verarbeitungstemperatur, etc.) überwacht werden und ist gegenüber Abweichungen sehr sensibel. Die Prozeßführung sollte demzufolge weitestgehend automatisiert ablaufen, da bei Abweichungen das gesamte eingeschäumte Produkt Ausschuß wird und der eingeschäumte Gegenstand erst nach manuellem "Schälen" wieder der Produktion zugeführt werden kann.The entire foaming process must - in order to be able to be controlled reproducibly - be monitored in all parameters (times, processing temperature, etc.) and is very sensitive to deviations. The process control should therefore be largely automated, since in case of deviations, the entire foamed product is rejected and the foamed object can be returned to production only after manual "peeling".
