Description

Kältegerät mit Siphon im Kondensatablauf  Refrigeration unit with siphon in condensate drain
Die vorliegende Erfindung betrifft ein Kältegerät, insbesondere ein Haushaltskältegerät, mit einem von einer Wärmedämmschicht umgebenen Innenraum, einem den Innenraum kühlenden Verdampfer und einem von dem Verdampfer durch die Wärmedämmschicht ins Freie führenden Kondensatablauf. The present invention relates to a refrigeration appliance, in particular a domestic refrigeration appliance, with an interior space surrounded by a thermal barrier coating, an evaporator cooling the interior space and a condensate outlet leading from the evaporator through the thermal barrier coating into the open air.
Wenn ein solcher Kondensatablauf während des Betriebs des Kältegeräts frei passierbar ist, dann findet über den Kondensatablauf ständig Luftaustausch mit der Umgebung statt, und Wärme und Feuchtigkeit gelangen unerwünschterweise über den Kondensatablauf in den Innenraum. Um dies zu unterbinden, ist zum Beispiel aus DE 10 2008 040 430 A1 bekannt, einen Siphon im Kondensatablauf vorzusehen, der dadurch, dass er jederzeit flüssiges Wasser enthält, Luft nur dann zwischen dem Innenraum und der Umgebung passieren lässt, wenn eine ausreichend große Druckdifferenz zwischen Drinnen und Draußen besteht. If such a condensate drain is freely passable during operation of the refrigerator, then takes place on the condensate drain constantly exchange of air with the environment, and heat and moisture pass undesirably on the condensate drain into the interior. In order to prevent this, it is known, for example, from DE 10 2008 040 430 A1 to provide a siphon in the condensate drain which, by containing liquid water at all times, allows air to pass between the interior and the environment only if there is a sufficiently large pressure difference between inside and outside.
Ein solcher Siphon kann, zumindest bei einem Kältegerät, dessen Innenraum Temperaturen unter 0 Grad Celsius erreicht, nur außerhalb der Wärmedämmschicht angeordnet sein, da ein Gefrieren von in dem Siphon enthaltenen Wasser diesen verstopfen und unbrauchbar machen würde. Den Siphon im Maschinenraum unterzubringen, ist schwierig, da er weder die Kühlung der dort vorhandenen Komponenten blockieren noch sich an diesen soweit erhitzen darf, dass er in kurzer Zeit trockenfällt und die Luftdichtigkeit des Siphons zwischen zwei Abtauzyklen nicht sichergestellt ist. Auch die Anbringung des Siphons an einer Rückwand des Geräts ist problematisch, da dies entweder eine Verkleinerung des dort üblicherweise vorgesehenen Rückwandverdampfers oder eine Vorverlegung der Wärmedämmschicht der Rückwand erfordert und damit einen deutlichen Verlust an nutzbarem Volumen mit sich bringt. Such a siphon, at least in a refrigerator whose interior reaches temperatures below 0 degrees Celsius, be located only outside of the thermal barrier coating, as a freezing of water contained in the siphon would make it clogged and unusable. It is difficult to place the siphon in the machine room, as it can neither block the cooling of the components present there nor heat them to such an extent that it dries in a short time and the airtightness of the siphon between two defrost cycles is not ensured. The attachment of the siphon to a rear wall of the device is problematic because this requires either a reduction of the usually provided there backwall evaporator or a forward installation of the thermal barrier coating of the rear wall and thus brings a significant loss of usable volume with it.
Aufgabe der Erfindung ist, ein Kältegerät anzugeben, das einen einfachen und platzsparenden Einbau eines Siphons im Kondensatablauf ermöglicht. The object of the invention is to provide a refrigeration device that allows a simple and space-saving installation of a siphon in the condensate drain.
Die Aufgabe wird gelöst, indem bei einem Kältegerät, insbesondere einem Haushaltskältegerät, mit einem von einer Wärmedämmschicht umgebenen Innenraum, einen den Innenraum kühlenden Verdampfer und einen von dem Verdampfer durch die Wärmedämmschicht ins Freie führenden, einen Siphon aufweisenden Kondensatablauf der Siphon an der Innenseite der Wärmedämmschicht angeordnet und durch eine Abtauheizung beheizbar ist. Im Innenraum ist der Siphon relativ leicht unterzubringen, ohne dass dafür eine Verlagerung der Wärmedämmschicht und damit ein merklicher Verlust an nutzbarem Volumen verbunden ist. Die Gefahr, dass infolge vorzeitigen Verdunstens des Wassers im Siphon der Kondensatablauf luftdurchlässig wird, ist durch die niedrige Temperatur, auf der der Siphon gehalten ist, beseitigt. Indem der Kondensatablauf auf einem kurzen, vorzugsweise geradlinigen Weg durch die Wärmedämmschicht geführt wird, kann auch die Schwächung der Dämmwirkung der Wärmedämmschicht durch den Kondensatablauf auf ein Minimum begrenzt werden. Solange das Wasser im Kondensatablauf gefroren ist, bildet es einen unbeweglichen Verschluss, der auch die Entstehung von Blubbergeräuschen verhindert, die bei einem mit flüssigem Wasser gefüllten Siphon entstehen, wenn beispielsweise warme Luft, die bei einem Öffnen der Tür in den Innenraum des Kältegeräts gelangt ist, sich darin abkühlt und dadurch Umgebungsluft über den Siphon angesaugt wird. The object is achieved by providing in a refrigeration appliance, in particular a household refrigeration appliance, with an interior surrounded by a thermal barrier coating, a vaporizer cooling the interior and leading from the evaporator through the thermal barrier coating into the open, a siphon having condensate drainage of the siphon on the inside of the thermal barrier coating and can be heated by a defrost heater. In the interior of the siphon is relatively easy to accommodate, without causing a shift of the thermal barrier coating and thus a significant loss of usable volume is connected. The risk that due to premature evaporation of the water in the siphon, the condensate drain is permeable to air, is eliminated by the low temperature at which the siphon is held. By the condensate drain is guided on a short, preferably rectilinear path through the thermal barrier coating, the attenuation of the insulating effect of the thermal barrier coating can be limited by the condensate drain to a minimum. As long as the water is frozen in the condensate, it forms a immovable closure, which also prevents the formation of Blubbergeräuschen that arise in a filled with liquid water siphon, for example, warm air that has entered the interior of the refrigerator when opening the door , Cools itself and thereby ambient air is sucked in through the siphon.
Die Abtauheizung des Siphons sollte an eine Abtauheizung für den Verdampfer funktionsmäßig gekoppelt sein, um sicherzustellen, dass der Siphon durchlässig ist oder rechtzeitig durchlässig wird, wenn der Verdampfer abgetaut wird und Kondensat von dort über den Siphon abzuführen ist. The siphon defrost heater should be operatively coupled to a defrost heater for the evaporator to ensure that the siphon is permeable or timely permeable when the evaporator is defrosted and condensate is drained from it via the siphon.
Denkbar ist, Heizungen des Siphons und des Verdampfers zeitversetzt zu betreiben, insbesondere kann die Heizung des Siphons kurz vor Beginn eines Abtauvorgangs in Betrieb genommen werden, um sicherzustellen, dass der Inhalt des Siphons rechtzeitig flüssig und somit der Siphon durchlässig ist, wenn der Fluss von Kondensat vom Verdampfer einsetzt. It is conceivable to operate heaters of the siphon and of the evaporator with a time delay, in particular the heater of the siphon can be put into operation shortly before the beginning of a defrosting operation to ensure that the contents of the siphon are liquid in time and thus the siphon is permeable when the flow of Condensate from the evaporator begins.
Da in der Praxis auch der Verdampfer eine gewisse Betriebszeit seiner Abtauheizung benötigt, bis der Fluss des Kondensats einsetzt, können beide Heizungen auch über einen gleichen Schalter gesteuert und so gleichzeitig betrieben werden; einer bevorzugten Ausgestaltung zufolge kann für den Verdampfer und für den Siphon eine gemeinsame Abtauheizung vorgesehen sein. Wenn der Innenraum in eine Lagerkammer und eine Verdampferkammer unterteilt ist, ist der Siphon vorzugsweise am Boden einer Vertiefung in der Verdampferkammer angeordnet. Since in practice, the evaporator requires a certain operating time of its defrosting until the flow of condensate begins, both heaters can also be controlled by a same switch and operated simultaneously; According to a preferred embodiment, a common defrost heater may be provided for the evaporator and for the siphon. When the interior space is divided into a storage chamber and an evaporation chamber, the siphon is preferably arranged at the bottom of a depression in the evaporation chamber.
Die Abtauheizung kann sich über der Vertiefung erstrecken, um diese großflächig, insbesondere durch Strahlung, zu erwärmen. The defrost heater may extend over the recess to heat them over a large area, in particular by radiation.
Die Abtauheizung kann sich zwischen dem Verdampfer und der Vertiefung erstrecken, um gleichzeitig Wärme nach unten an die Vertiefung und nach oben an den Verdampfer abzugeben. The defrost heater may extend between the evaporator and the well to simultaneously deliver heat down to the well and up to the evaporator.
Die Abtauheizung kann insbesondere platten- oder stabförmig sein. The defrost heater may in particular be plate-shaped or rod-shaped.
Damit die Abtauheizung den Siphon in vertretbar kurzer Zeit durch Strahlung auftauen kann, muss ihre Betriebstemperatur deutlich über 0°C liegen; dann kann sie auch den Verdampfer durch Strahlung beheizen. For the defrost heater to thaw the siphon in a reasonably short time by radiation, its operating temperature must be well above 0 ° C; then it can also heat the evaporator by radiation.
Der Boden der Vertiefung sollte zum Siphon abschüssig sein, zum einen um das Kondensat am Siphon zu versammeln, zum anderen, um einen hochgelegenen Teil des Bodens von Wasser bzw. Eis freihalten zu können, so dass dieser bei einem Abtauen Strahlung direkt von der darüber liegenden Abtauheizung aufnehmen und die Strahlungswärme an das Eis im Siphon weiterleiten kann. The bottom of the well should slope down to the siphon, firstly to collect the condensate at the siphon, secondly to keep a high part of the bottom free of water or ice so that it will directly deflect radiation from the overlying defrost Pick up defrost heating and forward the radiant heat to the ice in the siphon.
Um den Wärmeleitvorgang zu effektivieren, kann der Boden der Vertiefung mit einer Infrarot-absorbierenden Oberflächenschicht versehen sein. In order to enhance the heat conduction process, the bottom of the well may be provided with an infrared absorbing surface layer.
Um eine schnelle Übertragung der aufgenommenen Wärme auf das Eis zu gewährleisten, kann ferner der Boden der Vertiefung zumindest teilweise metallisch sein. In order to ensure a rapid transfer of the absorbed heat to the ice, furthermore, the bottom of the recess may be at least partially metallic.
Der Siphon ist zweckmäßigerweise gebildet durch einen über den Boden der Vertiefung aufragenden Stutzen und einen über den Stutzen gestülpten Becher. Eine Unterkante des Bechers sollte maximal 2 mm unter der Oberkante des Stutzens liegen, um die Menge des Wassers, die zum Durchlässigmachen des Siphons aufgetaut werden muss, zu begrenzen. The siphon is expediently formed by a nozzle projecting over the bottom of the depression and a cup which is put over the neck. A bottom edge of the cup should be at most 2 mm below the top of the nozzle to limit the amount of water that must be thawed to make the siphon porous.
Um dieses Auftauen zu beschleunigen, kann ferner eine der Abtauheizung zugewandte Oberfläche des Siphons, insbesondere eine Oberseite des Bechers, mit einer Infrarotabsorbierenden Oberflächenschicht versehen sein. In order to accelerate this thawing, furthermore, a surface of the siphon facing the defrost heater, in particular an upper side of the beaker, can be provided with an infrared-absorbing surface layer.

Fig. 1 zeigt einen schematischen Querschnitt durch ein NoFrost-Haushaltskältegerät mit einem Korpus 1 und einer Tür 2, die jeweils mit einer Wärmedämmschicht 3 ausgeschäumt sind und einen Innenraum 4 umschließen. Der Innenraum 4 ist durch eine Trennwand 5 unterteilt in eine über die Tür 2 zugängliche Lagerkammer 6 und eine Verdampferkammer 7, die sich in Hochkant-Orientierung zwischen der Trennwand 5 und einer Rückwand 8 des Korpus 1 erstreckt. Die Verdampferkammer 7 ist zu einem großen Teil ausgefüllt von einem Verdampfer 9, typischerweise einem Lamellenverdampfer. Ein Lüfter 10 ist in einer Öffnung der Trennwand 5 angeordnet, um, wenn der Verdampfer 9 in Betrieb ist, Luftzirkulation zwischen der Lagerkammer 6 und der Verdampferkammer 7 anzutreiben. Eine horizontale oder nach vorn leicht abschüssige Wand 1 1 des Korpus 1 trennt die Verdampferkammer 7 von einem Maschinenraum 12, der außerhalb der Wärmedämmschicht 3 liegt und unter anderem einen Verdichter 13 enthält. 1 shows a schematic cross section through a NoFrost domestic refrigeration appliance with a body 1 and a door 2, which are each foamed with a thermal barrier coating 3 and enclose an interior 4. The interior 4 is subdivided by a partition wall 5 into a storage chamber 6 which is accessible via the door 2 and an evaporation chamber 7 which extends in upright orientation between the dividing wall 5 and a rear wall 8 of the body 1. The evaporator chamber 7 is filled to a large extent by an evaporator 9, typically a finned evaporator. A fan 10 is disposed in an opening of the partition wall 5 to drive air circulation between the storage chamber 6 and the evaporator chamber 7 when the evaporator 9 is in operation. A horizontal or forward slightly sloping wall 1 1 of the body 1 separates the evaporator chamber 7 of a machine room 12 which is outside the thermal barrier coating 3 and contains, inter alia, a compressor 13.
Ein aus Kunststoff tiefgezogener Innenbehälter trennt in fachüblicher Weise den Innenraum 4 von der Wärmedämmschicht 3. Am Boden der Verdampferkammer 7 ist in dem Innenbehälter eine Vertiefung 14 geformt, die sich über die gesamte Breite der Verdampferkammer 7 erstreckt. Ein Siphon 15 am tiefsten Punkt der Vertiefung 14 bildet den Ausgangspunkt eines Kondensatablaufs 16, der sich vertikal durch die Wand 1 1 hindurch zu einer vom Verdichter 13 beheizten Verdunstungsschale 17 im Maschinenraum 12 erstreckt. A plastic deep-drawn inner container separates in a conventional manner the interior 4 of the thermal barrier coating 3. At the bottom of the evaporator chamber 7, a recess 14 is formed in the inner container, which extends over the entire width of the evaporator chamber 7. A siphon 15 at the lowest point of the recess 14 forms the starting point of a condensate drain 16, which extends vertically through the wall 1 1 through to a heated evaporator shell 17 in the engine room 12 from the compressor 13.
Fig. 2 zeigt den Siphon 15 und dessen Umgebung in einem vergrößerten Schnitt gemäß einer ersten Ausgestaltung der Erfindung. Der Siphon 15 umfasst einen zylindrischen Stutzen 18, der sich vom Boden der Vertiefung 14 nach oben erstreckt, sowie eine Schale oder einen Becher 19, der kopfüber über das freie Ende des Stutzens 18 gestülpt ist. Um einen Boden 20 des Bechers 19 von der Oberkante 21 des Stutzens 18 beabstandet zu halten, kann die umlaufende Wand 22 des Bechers 19 mit einzelnen Füßchen 23 versehen sein, die sich rings um den Stutzen 18 am Boden der Vertiefung 14, hier in einem den Stutzen 18 umgebenden Graben 24, abstützen. Fig. 2 shows the siphon 15 and its surroundings in an enlarged section according to a first embodiment of the invention. The siphon 15 comprises a cylindrical neck 18, which extends from the bottom of the recess 14 upwards, and a shell or a cup 19, which is inverted over the free end of the nozzle 18. In order to keep a bottom 20 of the cup 19 spaced from the top edge 21 of the nozzle 18, the circumferential wall 22 of the cup 19 may be provided with individual feet 23, which surrounds the nozzle 18 at the bottom of the recess 14, here in a Neck 18 surrounding trench 24, support.
Eine elektrische Widerstandsheizung 25 ist an einer der Wärmedämmschicht 3 zugewandten Außenseite des Grabens 24 angebracht und gemeinsam mit einer am Lamellenverdampfer 9 angebrachten Widerstandsheizung 26 betreibbar, um jeweils bei einem Abtauen des Verdampfers 9 rechtzeitig auch das Wasser im Graben 24 aufzutauen, so dass ein freier Abfluss des Tauwassers vom Verdampfer 9 über den Kondensatablauf 16 zur Verdunstungsschale 17 gewährleistet ist. Nach Abschluss des Abtauvorgangs bleibt der Graben 24 bis zur Oberkante 21 des Stutzens 18 mit Wasser gefüllt, so dass, sobald der Verdampfer 9 wieder kühlt, das Wasser im Graben 24 gefriert und den Siphon 15 dicht verschließt. An electrical resistance heater 25 is attached to one of the thermal barrier coating 3 facing outside of the trench 24 and operable together with a mounted on the fin evaporator 9 resistance heater 26 to defrost at a defrosting of the evaporator 9 in time, the water in the trench 24, so that a free drain the condensation water is ensured by the evaporator 9 via the condensate drain 16 to the evaporation tray 17. After completion of the defrosting of the trench 24 remains filled up to the upper edge 21 of the nozzle 18 with water, so that as soon as the evaporator 9 cools again, the water in the trench 24 freezes and closes the siphon 15 tight.
Fig. 3 zeigt einen schematischen Schnitt durch den Siphon 15 gemäß einer bevorzugten zweiten Ausgestaltung der Erfindung. Eine plattenformige Widerstandsheizung 27 ist hier horizontal orientiert über der Vertiefung 14 und unter dem Lamellenverdampfer 9 angeordnet. An ihrer Stelle könnte auch eine stabförmige Heizung vorgesehen und insbesondere geradlinig senkrecht zur Schnittebene orientiert sein oder in einer horizontalen Ebene in Mäandern verlaufen. Eine zweite Heizung könnte wie die Heizung 26 der Fig. 2 unmittelbar am Lamellenverdampfer 9 angeordnet und zusammen mit der Widerstandsheizung 27 betrieben sein, um den Verdampfer 9 zu beheizen, wenn gleichzeitig die Widerstandsheizung 27 das Wasser im Siphon 15 auftaut. Bei der in Fig. 3 gezeigten Ausgestaltung erwärmt von der Widerstandsheizung 27 abgegebene Infrarotstrahlung sowohl den Lamellenverdampfer 9 als auch den Siphon 15. Fig. 3 shows a schematic section through the siphon 15 according to a preferred second embodiment of the invention. A plate-shaped resistance heater 27 is horizontally oriented here above the depression 14 and below the lamella evaporator 9 arranged. In its place could also be provided a rod-shaped heater and in particular be oriented rectilinearly perpendicular to the cutting plane or extend in a horizontal plane in meanders. A second heater could, like the heater 26 of FIG. 2, be disposed directly on the fin evaporator 9 and operated together with the resistance heater 27 to heat the evaporator 9, if at the same time the resistance heater 27 thaws the water in the siphon 15. In the embodiment shown in FIG. 3, infrared radiation emitted by the resistance heater 27 heats both the fin evaporator 9 and the siphon 15.
Von der Heizung 27 nach unten abgegebene Infrarotstrahlung wird einerseits vom Becher 19, andererseits vom Boden der Vertiefung 14 aufgefangen. Der Becher 19 gibt die von ihm aufgefangene Wärme über die in den den Stutzen 18 umgebenden Eiskörper 28 eintauchenden unteren Rand der Wand 22 an den Eiskörper 28 ab. Damit vom Verdampfer 9 her zufließendes Tauwasser ablaufen kann, muss der Eiskörper 28 nicht vollständig aufgetaut sein, es genügt, wenn entlang des Umfangs der Wand 22 an einer Stelle das Eis von außen nach innen durchgehend verflüssigt ist. Je geringer der vertikale Überlapp d zwischen der Wand 22 und dem Stutzen 18 ist, um so kleiner ist die Menge des Eises unmittelbar an der Oberfläche der Wand 22, an die der Becher 19 seine Wärme abgibt und die verflüssigt werden muss, um den Siphon 15 durchlässig zu machen. From the heater 27 downwardly emitted infrared radiation is collected on the one hand by the cup 19, on the other hand from the bottom of the recess 14. The cup 19 discharges the heat collected by it via the lower edge of the wall 22 dipping into the ice body 28 surrounding the socket 18 to the ice body 28. In order for the condensing unit to be able to drain the evaporator 9, the ice body 28 does not have to be completely thawed, it is sufficient if the ice is liquefied continuously from the outside to the inside along the circumference of the wall 22 at one point. The smaller the vertical overlap d between the wall 22 and the stub 18, the smaller the amount of ice immediately adjacent to the surface of the wall 22 to which the cup 19 gives off its heat and which must be liquified to form the siphon 15 to make it permeable.
Um einen zügigen Abfluss des Tauwassers zu gewährleisten, ist es dennoch hilfreich, wenn der Eiskörper 28 alsbald vollständig aufgetaut ist. Die zum Siphon 15 hin schräg abschüssigen Wände 29 der Vertiefung 14 und die geringe Höhe des Stutzens 18 gewährleisten, dass am Ende jedes Abtauvorgangs nur ein kleiner Teil der Wände 29 rings um den Stutzen 18 von Wasser bedeckt ist; der überwiegende Teil der Wände 29, der höher als die Oberkante 21 des Stutzens 18 liegt, bleibt daher während des Kühlbetriebs eisfrei und erwärmt sich beim nächsten Abtauvorgang schnell durch die Strahlung der Heizung 27. Um diese Wärme zügig zum Eiskörper 28 hin abzuleiten, können die Wände 29 mit einem dünnen Blech 30 oder einer Metallfolie belegt sein; um die Absorption der Infrarot-Strahlung zu effektivieren, können das Blech 30 und der Becher 19 jeweils noch mit einer Infrarot-absorbierenden Beschichtung 31 versehen sein. Fig. 4 zeigt als dritte Ausgestaltung der Erfindung einen schematischen Schnitt durch einen Siphon 15 und dessen Umgebung in einem Kältegerät mit einer horizontal unter einer Decke 32 des Korpus angeordneten Verdampferkammer 7. Die Heizung 27 erstreckt sich hier unter einer Breitseite des Lamellenverdampfers 9 und kann diesen sowohl durch Strahlung als auch durch unmittelbaren Kontakt beheizen. Zwischen einem vorderen Bereich der Heizung 27 und der die Verdampferkammer 7 von der Lagerkammer 6 trennenden Wand 5 ist eine Infrarot-reflektierende Folie 33 angeordnet, um die Wärmeabgabe an die darunterliegende, die Verdampferkammer 7 von der Lagerkammer 6 trennende Wand 5 zu minimieren. Folie 33 und Wand 5 sind zur Rückwand 8 abschüssig, um vom Verdampfer 9 ablaufendes Tauwasser der Vertiefung 14 zuzuführen, die hier in einem rückwärtigen Teil der Wand 5 angeordnet ist Ein über die Folie 33 hinausragender hinterer Bereich 34 der Heizung 27 gibt Wärmestrahlung nach unten ab, um die Vertiefung 14 und den - hier genauso wie in der Ausgestaltung der Fig. 2 aufgebauten - Siphon 15 zu beheizen. In order to ensure a rapid outflow of condensation water, it is still helpful when the ice body 28 is thawed completely soon. The siphon 15 obliquely sloping walls 29 of the recess 14 and ensure the low height of the nozzle 18 that at the end of each defrosting process, only a small part of the walls 29 is covered around the nozzle 18 of water; the majority of the walls 29, which is higher than the upper edge 21 of the nozzle 18, therefore remains free of ice during the cooling operation and heats up quickly at the next defrosting by the radiation of the heater 27. To dissipate this heat quickly to the ice body 28, the Walls 29 may be covered with a thin sheet 30 or a metal foil; In order to make the absorption of the infrared radiation more effective, the sheet 30 and the cup 19 may each be provided with an infrared absorbing coating 31. Fig. 4 shows a third embodiment of the invention is a schematic section through a siphon 15 and its surroundings in a refrigerator with a horizontally arranged under a ceiling 32 of the body evaporator 7. The heater 27 extends here under a broad side of the finned evaporator 9 and can this both by radiation and by direct contact heat. Between a front portion of the heater 27 and the evaporator chamber 7 from the storage chamber 6 separating wall 5, an infrared-reflective film 33 is arranged to minimize the heat transfer to the underlying, the evaporator chamber 7 of the storage chamber 6 separating wall 5. Foil 33 and wall 5 are sloping to the rear wall 8 to 9 running out of the evaporator condensate water to the recess 14, which is arranged here in a rear part of the wall 5 on the film 33 protruding rear portion 34 of the heater 27 emits heat radiation down in order to heat the depression 14 and the siphon 15 - constructed here in the same way as in the embodiment of FIG. 2.
