Description

Die Erfindung betrifft ein Kühlgerät, insbesondere einen Mehrtemperaturen-Kühl­schrank, mit - in einem wärmeisolierten Gehäuse durch Zwischenböden und/oder Zwi­schenwände thermisch voneinander getrennten, vorzugsweise separat verschließbaren Fächern unterschiedlicher Betriebstemperatur, deren Temperaturniveau durch über in den Wänden angeordnete, mit thermostatgesteuerten Regelorganen, wie Reglerklap­pen oder dgl. versehene Luftkanäle umgewälzte Kaltluft aufrecht erhalten wird, die über im Gehäuse verdeckt angeordnete Wärmetauscher eines Kälteaggregates erzeugt wird.The invention relates to a cooling device, in particular a multi-temperature refrigerator, with compartments of different operating temperatures which are thermally separated from one another in a heat-insulated housing by intermediate shelves and / or intermediate walls and whose temperature level is provided by thermostatically controlled control elements, such as control flaps, arranged in the walls or the like. Provided air channels circulated cold air is maintained, which is generated via heat exchangers arranged in the housing of a refrigeration unit.

Bei bekannten Kühlgeräten der genannten Art ist es üblich, die thermostatisch ge­steuerten Reglerklappen zur Regelung der in den verschiedenen Fächern herrschenden unterschiedlichen Betriebstemperatur versenkt in die in den Wänden, Böden oder Decken des wärmeisolierten Gehäuses verlaufende Luftkanäle einzubauen. Hierzu ist es jedoch erforderlich, die Reglerklappen räumlich weit voneinander entfernt einzeln zu montieren. Dies ist insbesondere bei Geräten mit großem Rauminhalt der Fall. Sofern es sich hierbei um elektromotorisch angetriebene Reglerklappen handelt, müs­sen die zur Stromversorgung notwendigen Leitungen über weite Strecken im Gehäuse verlegt werden. Insbesondere bei Mehrtemperaturen-Kühlschränken mit einer Vielzahl von Fächern unterschiedlicher Temperatur ist hierzu ein großer Montageaufwand er­forderlich, zumal es üblich ist, die Reglerklappen ebenso wie die elektrischen Lei­tungen unauffällig und verdeckt im hinteren Bereich des Gehäuses im Gerät anzu­ordnen.In known cooling devices of the type mentioned, it is customary to install the thermostatically controlled control flaps for regulating the different operating temperatures prevailing in the various compartments in the air ducts running in the walls, floors or ceilings of the heat-insulated housing. To do this, however, it is necessary to individually mount the control flaps far apart from each other. This is particularly the case for devices with a large volume. If this is an electromotive-driven regulator flap, the cables required for power supply must be in the housing over long distances be relocated. In particular in the case of multi-temperature refrigerators with a large number of compartments of different temperatures, this requires a large amount of assembly work, especially since it is customary to arrange the control flaps as well as the electrical lines inconspicuously and concealed in the rear area of the housing in the device.

Bei einer derart auseinandergezogenen Anordnung der Reglerklappen im hinteren Be­reich des Gehäuses ist es auch shwierig, diese und deren Antrieb im Bedarfsfalle zu warten, einzuregeln oder deren Funktion zu überprüfen. Schließlich ist es bei der üblichen Einzelanordnung der Reglerklappen erforderlich, an entsprechenden Stellen in den Luftkanälen besondere Räume vorzusehen, in denen die Reglerklappen mit ih­rem Antrieb montiert werden können Hierdurch wird die Kanalführung im Gehäuse des Gerätes sehr kompliziert.With such an extended arrangement of the regulator flaps in the rear area of the housing, it is also difficult to maintain, regulate, or check their function, if necessary, and their drive. Finally, in the usual individual arrangement of the control flaps, it is necessary to provide special spaces at corresponding points in the air ducts, in which the control flaps can be mounted with their drive.

Der Erfindung liegt die Aufgabe zugrunde, den Aufbau der eingangs näher bezeichne­ten Kühlgeräte durch einfache Maßnahmen zu verbessern und insbesondere die mit dem Einbau der Reglerklappen und deren Antrieb im Zusammenhang stehenden Pro­bleme günstig zu lösen.The invention has for its object to improve the structure of the cooling devices specified in the introduction by simple measures and in particular to solve the problems associated with the installation of the control flaps and their drive cheap.

Diese Aufgabe wird nach der vorliegenden Erfindung dadurch gelöst, daß mehrere Regelorgane für verschiedenen Fächern unterschiedlicher Betriebstemperatur zugeord­nete Kaltlufströme in einem als vormontierte Einheit im Gehäuse einsetzbaren Ver­teiler angeordnet sind, welcher mit Anschlußöffnungen für die verschiedenen Luftka­näle ausgestattet ist.This object is achieved according to the present invention in that several control elements for different compartments of different operating temperature associated cold air flows are arranged in a distributor which can be used as a preassembled unit in the housing and which is equipped with connection openings for the various air ducts.

Aufgrund der erfindungsgemäßen Zusammenfassung mehrerer Reglerklappen und de­ren Antriebe in einem als vormontierte Einheit in das Gehäuse einsetzbaren Vertei­ler gelingt es, die Konstruktion eines derartigen Gerätes besonders übersichtlich zu gestalten und dessen Montage und Wartung sehr zu vereinfachen.Due to the inventive combination of several control flaps and their drives in a distributor that can be inserted into the housing as a preassembled unit, it is possible to make the construction of such a device particularly clear and to simplify its assembly and maintenance.

Bei einem Kühlgerät mit einem von Luftkanälen durchzogenen, den Wärmetauscher und ein Gebläse aufnehmenden Zwischenboden hat sich als besonders günstig erwie­sen, wenn gemäß einer vorteilhaften Weiterbildung des Gegenstandes der Erfindung vorgesehen ist, daß der Verteiler als ein im wesentlichen quaderförmiger Körper ausgebildet ist, welcher im hinteren Bereich unter dem, den Wärmetauscher auf­nehmenden Zwischenboden in der von den Seitenwänden und der Rückwand des Ge­häuses gebildeten Nische eingepaßt und mit Anschlußöffnungen für die dort verlau­fenden Luftkanäle versehen ist.In a cooling device with an intermediate floor through which air channels pass, the heat exchanger and a fan have proven to be particularly advantageous if, according to an advantageous development of the subject matter of the invention, it is provided that the distributor as an essentially cuboid body is formed, which is fitted in the rear area under the intermediate floor receiving the heat exchanger in the niche formed by the side walls and the rear wall of the housing and is provided with connection openings for the air channels running there.

Um zu vermeiden, daß sich bei Stillstand des Gebläses in den unteren Fächern sich erwärmende Luft durch die Kanäle in darüberliegende Fächer tieferer Temperatur aufsteigen kann und dort die Temperatur ansteigen läßt, ist nach einer weiteren vorteilhaften Ausgestaltung des Gegenstandes der Erfindung vorgesehen, daß im Ver­teiler angeordnete Kanäle in Strömungsrichtung hinter den Regelklappen siphon­artig ausgebildet sind.In order to avoid that, when the fan in the lower compartments is at a standstill, warming air can rise through the ducts into overlying compartments of lower temperature and the temperature can rise there, according to a further advantageous embodiment of the object of the invention it is provided that arranged in the distributor Channels in the flow direction behind the control flaps are siphon-like.

Der sich in einem deratigen Siphon bildende Pfropfen spezifisch schwerer Kaltluft verhindert dabei auf einfache Weise, daß in dem Kanal aufsteigende wärmere Luft nach oben in das darüberliegende Fach gelangen kann.The plug of specifically heavy cold air that forms in a siphon of this type prevents in a simple manner that warmer air rising in the channel can reach the compartment above it.

Nach einer zusätzlichen vorteilhaften Weiterbildung des Gegenstandes der Erfindung ist vorgesehen, daß die Kanäle mit in Strömungsrichtung vor den Regelklappen gelegen, taschenförmigen Abscheider für Tauwasser ausgestattet sind.According to an additional advantageous development of the subject matter of the invention, it is provided that the channels are equipped with pocket-shaped separators for condensation water located in front of the control flaps in the direction of flow.

Hierdurch wird vermieden, daß sich während der Stillstandsphase des Gebläses an den Wänden der Kanäle niederschlagendes Tauwasser bis an die Reglerklappen ge­langt, wo es in der nächsten Kühlphase gefrieren und dadurch die Regelklappen durch vereisen blockieren kann.This prevents condensation from settling on the walls of the ducts during the standstill phase of the blower, reaching the control flaps, where it freezes in the next cooling phase and can thereby block the control flaps due to ice.

Als besonders günstig hat sich eine Konstruktion erwiesen, nach der der Verteiler mit einer Beleuchtungseinrichtung für das ihn aufnehmende Fach ausgestattet ist.A construction has proven to be particularly favorable according to which the distributor is equipped with a lighting device for the compartment receiving it.

Im dargestellten Ausführungsbei­spiel ist das Verteilerstück 30 aus zwei ineinandergeschachtelten und dicht ineinand­ergefügten Formteilen 36 und 37 aus Kunststoff-Hartschaum gebildet, welche zwi­schen sich Hohlräume für Luftkanäle 38 bzw. Kammern 39 zum Einbau des elektro­motorischen Antriebs 32 der Reglerklappen 31 aufnehmen. An seiner Frontseite ist der Verteiler 30 mit einer Kunststoffschale 40 verblendet in dejen zurückgesetzten unteren Bereich Austrittsöffnungen 41 für die hier austretenden Luftkanäle 38 ange­ordnet sind. An der unteren Hinterkante der Kunststoffschale 40 befinden sich fer­ner Augen 42, die zum Befestigen des Verteilers 30 an der Rückwand des Gehäuses 10 und in dem darin angeordneten wannenartigen Formteil 28 mit den Luftkanälen 27 dienen Die im Verteiler 30 in Strömungsrichtung hinter den Reglerklappen 31 der Klappenthermostate gelegenen Luftkanäle 38 sind siphonartig ausgebildet und zu diesem Zweck mit einer Vertiefung 43 versehen, in die jeweils von oben eine Trenn­wand hineinragt. Der Verteiler 30 ist ferner mit einer seitlich in einer Ausnehmung 44 angeordneten Beleuchtungseinrichtung in Form einer mit einer Glühlampe 45 ver­sehenen Lampenfassung für das ihm zugeordnete Fach 16 ausgestattet.The distributor 30 is designed as a substantially cuboid body, which is fitted in the rear area under the intermediate floor 12 receiving the heat exchanger 23 and the fan 24 in the niche formed by the side walls and the rear wall of the housing 10 and with connection openings 33, 34 and 35 is equipped for the corresponding air ducts. In the exemplary embodiment shown, the distributor piece 30 is formed from two nested and tightly interlocked molded parts 36 and 37 made of rigid plastic foam, which accommodate cavities for air channels 38 or chambers 39 for installing the electromotive drive 32 of the controller flaps 31. At its front, the distributor 30 is covered with a plastic shell 40 in the recessed lower region of which there are outlet openings 41 for the air channels 38 emerging here. On the lower rear edge of the plastic shell 40 there are also eyes 42, which are used to fasten the distributor 30 to the rear wall of the housing 10 and serve in the trough-like molded part 28 with the air channels 27 therein. The air channels 38 located in the distributor 30 in the flow direction behind the control flaps 31 of the flap thermostats are siphon-like and are provided with a recess 43 for this purpose, into each of which a partition protrudes from above . The distributor 30 is also equipped with a lighting device arranged laterally in a recess 44 in the form of a lamp socket provided with an incandescent lamp 45 for the compartment 16 assigned to it.

Die elektrischen Zuleitungen für die Energieversorung der elektromotorischen Antrie­be 32 der Klappenthermostaten sind auf der Rückseite des Verteilers 30 versenkt in einem Kanal 46 verlegt, aus dem sie seitlich hinter der Beleuchtungseinrichtung aus­treten. Sie sind mit deren elektrischen Zuleitungen zu einem Kabelstrang 47 zusam­mengefaßt, der mit einem gemeinsamen Stecker 48 versehen ist, dessen nicht darge­stelltes Gegenstück sich in einer Wand des Gehäuses 10 befindet.The electrical supply lines for the energy supply of the electromotive drives 32 of the flap thermostats are sunk on the back of the distributor 30 in a channel 46, from which they emerge laterally behind the lighting device. They are combined with their electrical leads to form a cable harness 47 which is provided with a common plug 48, the counterpart of which is not shown, is located in a wall of the housing 10.

Die Anschlußöffnung 33 bis 34 des Verteilers 30 sind jeweils von Dichtungsrah­men 49 und 50 umgeben, welche aus einem schwammförmigen elastischen Werk­stoff bestehen und ein luftdichtes Anschließen an die ihnen zugeordneten Anschlüsse der Luftkanäle in der Rückwand des Gehäuses 10 und im Zwischenboden 12 gewähr­leisten. Die Dichtungsrahmen erfüllen neben ihrer Dichtfunktion auch die Aufgabe, sich gelegentlich während der Stillstandsphase des Gebläses 24 in den Luftkanälen bildendes Schwitzwasser aufzusaugen und zu binden, damit es nicht an die Regler­klappen 31 gelangen kann. Das sich dort ansammelnde Schwitzwasser wird dann beim nächsten Einschalten des Aggregats durch den entstehenden Luftzug verdunstet, so daß es sich dann am Wärmetauscher 23 niederschlägt. Sollte das Schwitzwasser vor­übergehend gefroren sein, so gelangt es dennoch durch Sublimation an den kalten Wärmetauscher 23. Die die elektromotorischen Antriebe 32 der Klappenthermostate aufnehmenden Kammern 39 im Verteiler 40 sind auf dessen Rückseite mit Folien 51 dicht abgeklebt. Ebenso sind alle außenliegenden Trennfugen der den Verteiler 30 bildenden Kunststoff-Formteile 36 und 37 mit nicht dargestellte Klebebändern ab­gedichtet.The connection openings 33 to 34 of the distributor 30 are each surrounded by sealing frames 49 and 50, which consist of a sponge-like elastic material and ensure an airtight connection to the associated connections of the air channels in the rear wall of the housing 10 and in the intermediate floor 12. In addition to their sealing function, the sealing frames also perform the task of occasionally absorbing and binding condensation water forming in the air channels during the standstill phase of the fan 24, so that it cannot reach the control flaps 31. The condensation water that accumulates there is then evaporated by the resulting draft when the unit is next switched on, so that it is then deposited on the heat exchanger 23. If the condensation water is temporarily frozen, it nevertheless reaches the cold heat exchanger 23 by sublimation. The chambers 39 in the distributor 40, which accommodate the electromotive drives 32 of the flap thermostats, are sealed off with films 51 on the rear side thereof. Likewise, all external parting lines of the plastic molded parts 36 and 37 forming the distributor 30 are sealed with adhesive tapes (not shown).

Das Luftkanäle 27 an der Rückseite des Gehäuses 10 aufnehmende Formteil 28 weist zwei den Reglerklappen 31 zugeordnete Ausgänge 52 bzw. 53 auf, in deren Nähe jeweils eine als Tropfkante dienende Schwelle 54 bzw. 55 angeordnet ist. Mit deren Hilfe wird sich während der Stillstandszeiten des Gebläses 24 an der Wand des Formteils 28 bildendes Tauwasser in taschenförmige Abscheider 56 bzw. 57 ge­leitet und dort gesammelt. An der Unterkante der Ausgänge der Luftkanäle befinden sich jeweils Schürzen 58, welche verhindern, daß dort anfallendes Tauwasser in die Spalte an den Austrittsöffnungen der Luftkanäle in der Rückwand des Gehäuses 10 läuft.The air duct 27 on the back of the housing 10 receiving the molded part 28 has two outputs 52 and 53 assigned to the control flaps 31, in the vicinity of which a threshold 54 and 55 serving as a drip edge is arranged. With their help, condensation water forming on the wall of the molded part 28 is conducted into pocket-shaped separators 56 and 57 during the idle times of the fan 24 and collected there. At the lower edge of the exits of the air ducts there are aprons 58 which prevent condensation water from running into the gaps at the outlet openings of the air ducts in the rear wall of the housing 10.
