Es zeigen: Fig. 1, eine perspektive Ansicht. und Fig. 2, in grösserem Maßstab, einen Schnitt entlang der in Fig. 1 angegebenen Linie 2-2. They show: FIG. 1, a perspective view. and Fig. 2, on a larger scale Scale, a section along the line 2-2 indicated in Fig. 1.

Die dargestellte Kühltruhe weist einen Körper 1 auf, in welchem, wie bereits bekannt, vier Kühlschubladen 2, 3, 4, 5 angeordnet sind. Diese Truhe unterscheidet sich dadurch, dass sie eine Schublade 6 enthält, die in schematischer Weise als auf Kugellagern 7 im Körper 1 der Truhe gelagert dargestellt ist. Die Vorderseite der Schublade 6 ist mit bekannten magnetischen Mitteln ausgestattet, die mit dem Körper 1 eine dichtende Verbindung eingehen, wenn sich die Schublade in ihrer geschlossenen Position befindet, was ebenfalls in der Zeichnung ersichtlich ist. The freezer shown has a body 1 in which, as already known, four cooling drawers 2, 3, 4, 5 are arranged. This chest differs in that it contains a drawer 6, which in schematic Way is shown as being supported on ball bearings 7 in the body 1 of the chest. the The front of the drawer 6 is equipped with known magnetic means, which enter into a sealing connection with the body 1 when the drawer is in its closed position, which can also be seen in the drawing is.

Die Schublade 6 trägt die an ihr montierte Gruppe bestehend aus einem Motor 9 und einem Verdichter 10 mit einem Kondensator 11. Diese Einheit befindet sich im unteren Teil der Schublade. Im oberen Teil derselben befindet sich der mittels Stangen 13 abgestützte Verdampfer 12, wobei diese Stangen 13 starr mit der Schublade 6 verbunden sind. Ferner ist zuoberst in der Schublade 6 eine Motor-Ventilator-Gruppe 14 angeordnet, welche seitliche Oeffnungen 15 aufweist. Eine wärmeisolierende Wand 16, die eine Isolation zwischen dem oberen, den Verdampfer enthaltenden Teil der Schublade und dem unteren Teil derselben bildet, ist am Boden 17 des Körpers 1 befestigt. Diese Wand 16 weist an ihrem vorne, d.h. neben der Vorderfläche 8 der Schublade liegenden Rand eine Ausnehmung 18 auf, durch welche die zum Strömungskreis des flüssigen Kältemittels gehörenden Rohrleitungen hindurchgeführt sind, wobei diese Rohrleitungen den Verdampfer mit dem Kondensator verbinden. Oberhalb des Verdampfers ist ein an den Stangen 13 aufgehängtes Gefäss 20 angeordnet, das zur Aufnahme des Sondenswassers dient. Eine starr mit diesem Gefäss 20 verbundene Abflussleitung 21 durchquert ebenfalls die Ausnehmung 18 und das freie Ende dieser Abflussleitung befindet sich oberhalb eines zweiten Behalters 22, der auf dem Kondensator angeordnet ist. The drawer 6 carries the group mounted on it consisting of one Motor 9 and a compressor 10 with a condenser 11. This unit is located located in the lower part of the Drawer. Located in the upper part of the same the evaporator 12 supported by means of rods 13, these rods 13 being rigid are connected to the drawer 6. Furthermore, at the top of the drawer 6 is a Motor-fan group 14 is arranged, which has lateral openings 15. A heat insulating wall 16, which provides insulation between the top, the evaporator containing part of the drawer and the lower part of the same is at the bottom 17 of the body 1 attached. This wall 16 faces at its front, i.e. next to the front surface 8 of the drawer lying edge has a recess 18 through which the flow circuit pipelines belonging to the liquid refrigerant are passed, wherein these pipes connect the evaporator to the condenser. Above the evaporator is a suspended on the rods 13 vessel 20 is arranged to receive the Probe water is used. A discharge line rigidly connected to this vessel 20 21 also traverses the recess 18 and the free end of this drainage line is located above a second container 22, which is arranged on the condenser is.

Die dargestellte Kühltruhe funktioniert folgendermassen. The freezer shown works as follows.

Wenn, wie in der Zeichnung ersichtlich, die Schublade geschlossen ist und der Motor 9 läuft, dann saugt der durch den Motor angetriebe Ventilator-Propeller 23 frische Luft durch eine im Sockel des Truhenkörpers oberhalb der Schublade 6 vorhandene Oeffnung 24 an. Die derart angesaugte Luft dringt durch eine Oeffnung 25 im Körper 1 in den Innenraum des unteren Teils der Schublade ein, um den Motor und dann den Verdichter und den Kondensator abzukühlen.When, as can be seen in the drawing, the drawer is closed and the motor 9 is running, then the fan propeller driven by the motor sucks 23 fresh air through one in the base of the chest above the drawer 6 existing opening 24. The air sucked in in this way penetrates through an opening 25 in the body 1 in the interior of the lower part of the drawer to the motor and then cool the compressor and condenser.

Anschliessend verlässt die angesaugte Luft die Schublade durch ein an der Vorderseite derselben vorgesehenes Gitter 26. Die in der Fig..2 angegebenen Pfeile zeigen in schematischer Weise den Weg, den die angesaugte Luft ausgehend von der Oeffnung 24 bis zum Ausgang durch das Gitter 26 zurücklegt.Then the sucked in air leaves the drawer through a on the front of the same provided grid 26. The ones indicated in FIG Arrows show in a schematic way the path that the sucked in air starts out from the opening 24 to the exit through the grille 26.

Anderseits saugt der nicht speziell dargestellte Ventilator 14 die sich im unteren Teil der Kühlschubladen 2, 3, 4 und 5 befindliche Luft an und zwingt sie, den Verdampfer zu umströmen und sich dabei abzukühlen. Anschliessend wird die derart abgekühlte Luft in der Richtung des oberen Teils der Schubladen 2, 3, 4 und 5 durch die Oeffnungen 15 befördert. On the other hand, the fan 14, not specifically shown, sucks The air in the lower part of the cooling drawers 2, 3, 4 and 5 is forced them to flow around the evaporator and cool off in the process. Afterward the air thus cooled becomes in the direction of the upper part of the drawers 2, 3, 4 and 5 conveyed through the openings 15.

Die in die Fig. 1 eingezeichneten Pfeile geben in schematiscner Weise den Strömungsweg der Kühlluft innerhalb der Truhe an. Die Pfeile 27 symbolisieren die aus den Löchern 15 austretende Luft. Natürlich weist die Schublade 6 in ihrem oberen Teil neben der Schublade 2 eine Oeffnung auf, derart, dass die in 27 ankommende Luft in diese und die benachbarten Schubladen eindringen kann. The arrows shown in FIG. 1 show in a schematic manner the flow path of the cooling air inside the chest. The arrows 27 symbolize the air emerging from the holes 15. Of course, the drawer has 6 in its upper part next to the drawer 2, such that the arriving in 27 Air can get into this and the neighboring drawers.

Man sieht leicht ein, dass es genügt, die Schublade 6 aus dem Körper der Truhe herauszunehmen und diese sofort durch eine identische Schublade zu ersetzen, wenn die Installation einer Störung unterworfen ist oder eine fehlerhafte Stelle aufweist. Dadurch ist es möglich, den Betrieb der Installation innert kürzester Frist wieder aufzunehmen. Diejenige Schublade, die das oder die fehlerhaften Organe enthält, wird dann zwecks Ueberholung entfernt und gegebenenfalls in einer Werkstatt repariert. It is easy to see that it is sufficient to remove the drawer 6 from the body take it out of the chest and immediately replace it with an identical drawer, if the installation is subject to a malfunction or a faulty point having. This makes it possible to have the installation up and running within a very short time Deadline to resume. The drawer that contains the defective organ or organs contains, is then removed for the purpose of overhaul and, if necessary, in a workshop repaired.
