Claims (7)

1. Kühlgerät für einen Schaltschrank mit einer Kondensatabführeinheit, der eine Detektoreinrichtung zugeordnet ist, mittels der eine vorbestimmte oder eine vorbestimmbare Füllstandshöhe in einem Kondensatauffang er­ mittelbar ist, wobei die Detektoreinrichtung bei Erreichen der Füllstands­ höhe ein Warnsignal abgibt, dadurch gekennzeichnet, dass die Detektoreinrichtung einen Schwimmerschalter (30) mit einem Schwimmer (30.8) aufweist, der bei Erreichen der Füllstandshöhe einen elektrischen Schaltkreis zur Erzeugung des Warnsignales schließt oder öffnet.1. Cooling device for a control cabinet with a condensate discharge unit, which is assigned a detector device, by means of which a predetermined or a predeterminable fill level in a condensate collector is indirect, the detector device emitting a warning signal when the fill level is reached, characterized in that the detector device detects a Float switch ( 30 ) with a float ( 30.8 ), which closes or opens an electrical circuit for generating the warning signal when the level is reached. 2. Kühlgerät nach Anspruch 1, dadurch gekennzeichnet,
dass die Kondensatabführeinheit einen Kondensatsammler (10) aufweist, an dem eine Ableitung (20) angeschlossen ist, über die das anfallende Kondensat abführbar ist,
dass der Schwimmschalter (30) an die Ableitung (20) ankoppelbar ist, und
dass der Ableitung (20) ein Rückflußverhinderer (27) zugeordnet ist, der ein Abfließen des Kondensats aus der Ableitung (20) in Richtung zum Kondensatsammler (30) verhindert. 2. Cooling device according to claim 1, characterized in
that the condensate discharge unit has a condensate collector ( 10 ), to which a drain ( 20 ) is connected, via which the condensate can be discharged,
that the float switch ( 30 ) can be coupled to the derivative ( 20 ), and
that the discharge line ( 20 ) is assigned a backflow preventer ( 27 ) which prevents the condensate from flowing out of the discharge line ( 20 ) towards the condensate collector ( 30 ). 3. Kühlgerät nach Anspruch 2, dadurch gekennzeichnet, dass der Schwimmer (30.8) in einem Schwimmgehäuse (30.1) verstellbar gehalten ist, dass an das Schwimmergehäuse (30.1) eine Zuführleitung angekoppelt ist, die auch an die Ableitung (20) angeschlossen ist und die eine räum­ liche Verbindung zwischen der Ableitung (20) und dem Schwimmer­ gehäuse (30.1) mit einer Entlüftung (Entlüftungsleitung (30.10) Ent­ lüftungsbohrung (30.15) versehen ist.3. Cooling device according to claim 2, characterized in that the float ( 30.8 ) is held adjustable in a floating housing ( 30.1 ), that a feed line is coupled to the float housing ( 30.1 ), which is also connected to the discharge line ( 20 ) and which A spatial connection between the discharge line ( 20 ) and the float housing ( 30.1 ) is provided with a ventilation (ventilation line ( 30.10 ) ventilation hole ( 30.15 ). 4. Kühlgerät nach Anspruch 2 oder 3, dadurch gekennzeichnet, dass das Schwimmergehäuse (30.1) über die Zuführleitung (30.11) an einen Rohrabschnitt (30.1) angeschlossen ist, dass an den beiden Enden des Rohrabschnittes (30.14) Stutzen (30.12, 30.13.) angekoppelt sind, auf die Schlauchstücke (24, 26) der Ableitung (20) aufschiebbar sind.4. Cooling device according to claim 2 or 3, characterized in that the float housing ( 30.1 ) via the feed line ( 30.11 ) is connected to a pipe section ( 30.1 ), that at both ends of the pipe section ( 30.14 ) connecting piece (30.12, 30.13.) are coupled, on the tube pieces ( 24 , 26 ) of the derivative ( 20 ) can be pushed. 5. Kühlgerät nach einem der Ansprüche 1 bis 4, dadurch gekennzeichnet, dass die Ableitung (20) aus dem Kühlgerätgehäuse (14) herausgeführt an der Aussenseite einer Seitenwand (11) des Schaltschrankes (10) entlang­ geleitet und hier befestigt ist.5. Cooling device according to one of claims 1 to 4, characterized in that the derivative ( 20 ) from the cooling device housing ( 14 ) led out on the outside of a side wall ( 11 ) of the control cabinet ( 10 ) and is attached here. 6. Kühlgerät nach Anspruch 1, dadurch gekennzeichnet, dass der Schwimmerschalter (30) in einem als Kondensat-Auffangwanne ausgebildeten Kondensatsammler (16) angeordnet ist, die mit einem Kon­ densatablauf (17) versehen ist, an den die Ableitung (20) anschliessbar ist.6. A cooling device according to claim 1, characterized in that the float switch ( 30 ) is arranged in a condensate collector ( 16 ) designed as a condensate collecting trough, which is provided with a condensate drain ( 17 ) to which the discharge line ( 20 ) can be connected . 7. Kühlgerät nach Anspruch 5, dadurch gekennzeichnet,
dass der Schwimmerschalter (30) an einer Halterung (30.16) befestigt ist, und
dass die Halterung (30.16) mittels einer Federklammer (34) an einem, die Auffangwanne begrenzenden Steg (14.3), auswechselbar befestigt.7. Cooling device according to claim 5, characterized in
that the float switch ( 30 ) is attached to a bracket ( 30.16 ), and
that the holder ( 30.16 ) is exchangeably attached by means of a spring clip ( 34 ) to a web ( 14.3 ) delimiting the collecting trough.
