Description
für Elektromotorenfor electric motors
Gegenstand der Erfindung ist 'eine mit Lüftungsöfrhungen versehene Schutzwand gegen Spritzwasser für Elektromotoren, Derartige Schutzwände sind besonders in Nahrangsimttelverarbdtungsbetrieben, z. B. im Fleischereigewerbe, von großer Bedeutung·, da die Arbeitsmaschinen mit ihren elektrischen Antriebsmotoren Mer sehr oft mit Wasser abgewaschen werden müssen. to Zur Verhütung des Eindringens von Wasser hat man bekanntlich bisher die Lüftungsöffh'ungen im Gehäuse von Elektromotoren so gebildet, daß man in den Gehäusewänden muschelförmige, unten offene Ausbuchtungen anbrachte. Hierdurch ist das Eindringen von Spritzwasser zwar erschwert, jedoch besteht hierbei noch immer die Gefahr, daß beim Abspritzen und Abspülen nach oben gerichtete Wasserstrahlen in den Motor eindringen können. Zur Verhütung dieses Übelstandes werden deshalb gemäß der Erfindung je zwei muschelförmige, unten offene Ausbuchtungen spiegelbildlich einander zugeordnet. Hierdurch werden in die Lüftungsöffnung antretende, von unten nach :oben gerichtete Wasserstrahlen aufgefangen und nach unten abgelenkt, ohne 'die gefährdeten Teile im Motorinnem treffen zu können.The subject of the invention is' one with Protective wall provided with ventilation openings against splashing water for electric motors, such Protective walls are particularly useful in food processing plants, z. B. in the butcher industry, of great importance ·, since the working machines with their electrical Drive motors mer have to be washed with water very often. To prevent the ingress of water, it is known that the ventilation openings have hitherto been used formed in the housing of electric motors so that one in the housing walls made shell-shaped bulges open at the bottom. This is the penetration Although complicated by splash water, there is still the risk that Upward jets of water penetrate the engine when hosing down and rinsing can. To prevent this inconvenience, two shell-shaped, open at the bottom are therefore according to the invention Bulges assigned to one another in mirror image. This will get into the ventilation opening incoming, from bottom to: upward directed water jets caught and after distracted below without being able to hit the endangered parts inside the engine.
Eine besonders einfache Herstellung der Ausbuchtungen gemäß der Erfindung ergibt sich dann, wenn man zwei nur auf <einer Seite mit den bekannten muschelförmigen Ausbuchtungen versehene Bleche mit ihren flachen Seiten spiegelbildlich, aneinandersetzt, so· daß sie zusammen die Schutzwand bilden. Auf der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt. Es zeigenA particularly simple production of the bulges according to the invention results when you only have two on one side with the well-known shell-shaped bulges provided sheets with their flat sides mirror-inverted, placed against each other, so that they together form the protective wall. In the drawing, the invention is in an embodiment shown. Show it

In der Wandet sind die bekannten muschelförmigen Ausbuchtungen b angeordnet, die außen von Wandteilen c begrenzt sind und nur einen unten offenen Spalt d aufweisen. Auf der Innenseite sind spiegelbildlich zu diesen Ausbuchtungen gleichartige muschelförmige Ausbuchtungen angeordnet, die von entsprechenden Wandteileniß1 begrenzt sind. Das von außen in die Öffnungend gespritzte Wasser kann daher nicht in gerader Riehtung in das Innere des Motors gelangen bzw. dessen gefährdete Teile treffen, weil es durch die Ausbuchtung e nach unten abgelenkt wird. 'In the wall, the known shell-shaped bulges b are arranged, which are delimited on the outside by wall parts c and have only a gap d open at the bottom. On the inside, like a mirror image of these bulges, shell-shaped bulges that are delimited by corresponding wall parts 1 are arranged. The water sprayed from the outside into the openings d can therefore not get into the interior of the motor in a straight line or hit its endangered parts, because it is deflected downwards by the bulge e. '
