They consist of a small electric motor with a propeller (approx. 80), optionally with a temperature sensor, which is screwed onto the refrigerator behind the refrigerator. This allows the air to be ventilated completely from the room behind the vents at the radiators and thus fed into an air duct at the rear of the refrigerator door. · iJ -

The air flow is particularly good - especially when gas is used - due to the direct supply of air through the grilles.

Neither the wooden cladding used for the chimney nor the Actragate or M· is good. In our opinion, the ambient air temperature is also increased significantly due to the exhaust air.

Dl· Lösung gelingt eine« Lüfter «it den la kennseiebnenden Teil de· AaepruOh 1 genannten Merkaalen.The aim of this study is to design a fan of this type that is more effective. The solution is achieved by using the characteristics mentioned in the key part of test 1.

Diese Wirksamkeit let tu erreichen»indem man einen Ventilator In ein·· Oehiuee befestigt»und dl···· am Pahrseug ausen bündig an der oberen oder unteren LUftungsgltterabdeokung anbringt. Zweokmäflgerweise enteprlcht der Austritt de· Lttftergeniu··· dem Durchmesser dee Ventilatorblattes.So wird die gesammte wärme Luft.^ie sich hinter dem Kühlschrank befindet,herausgeeogen und durch den Unterdruckeffekt gleichzeitig kühle frische Luft durch das untere Lüftungsgitter angesogen,dieThis effectiveness can be achieved by attaching a fan to a housing and placing it on the outside of the fan, flush with the upper or lower ventilation grille. Ideally, the outlet of the fan should correspond to the diameter of the fan blade. This way, all the warm air behind the refrigerator is sucked out and, at the same time, cool, fresh air is sucked in through the lower ventilation grille due to the negative pressure effect.

die dann am Auetauscherrohr und. am Brenner ,sowie a» AhjaaVsmin entlang geführt wird. Dies·· LUftergehäuse ist nachträglich und einfach su montieren,und gegebenenfalls auch Tor einer Fahrt leicht abnehmbar.which is then guided along the exchanger pipe and the burner as well as the exhaust manifold. This fan housing can be easily installed later and, if necessary, can also be easily removed during a trip.

Die Neuerung wird anhand eines in den Zeichnungen dargestellten Aueführungsbeispiels näher erläutert.The innovation is explained in more detail using an example shown in the drawings.

Ebenfalls bleibt die wirkung dee Lüfter*The air housing (l) is attached to the upper air grille cover ( 2 ) through which the fan sucks out the warm air, whereby cool air flows through the lower grille (3) to the exchanger (4), burner (4a) and exhaust cabin (b). The motor (6) drives the propeller (7) into the narrower part of the air housing (l) which is adapted to the left screw diameter. The motor itself is attached to a support (β). The opening of the air housing (l) is secured by a cover (9) made of debris to prevent the rotating propeller from falling out. The fan housing (2) is placed on the ventilation grille (2), the ventilation frame, and glued in place. The fan can be switched on either manually or via a temperature sensor (10) or a timer (11), which can be switched on or off by means of the thermostat (1). The electrical cables can be laid either externally (through a door, window or flap) or directly via a plug-in contact which is located in the ventilation grille. The housing itself is made of weatherproof plastic which is painted in such a way that it can be adapted to the shape of the fan. The effect is the same if the fan (l) is placed on the lower grille (3), whereby the air flow is increased. The warm air is pushed through the upper ventilation grille and the warm air is pushed through the upper ventilation grille. The effect of the fan* also remains the same.
