Description
Gerät mit Metallgehäuse und Elektromotor. Die Gehäuse von elektrischen Geräten mit Elektromotor, zum Beispiel von Staub saugern, bestehen in der Regel aus Metall, vorzugsweise Leichtmetall. Damit sie beim Gebrauch den nötigen Schutz gegen Verlet zungen durch den elektrischen Strom bieten, müssen sie in irgendeiner Weise gegenKörper- schluss isoliert sein. Bislang wurden die Mo toren meist in der Weise in dem Gehäuse be festigt, dass sie seitlich und am Boden des Gehäuses mit Schrauben gehalten wurden, ohne vom Gehäuse elektrisch isoliert zu sein.
Gegenstand der Erfindung ist ein Gerät mit Metallgehäuse und Elektromotor, das da durch gekennzeichnet ist, dass der Motor von einer Tragvorrichtung aus elektrischem Iso lierstoff, zweckmässigerweise aus einer Trag platte, getragen wird, die ihrerseits mit dem Gehäuse fest verbunden ist. Vorzugsweise kann man zum Beispiel beim zylindrischen Gehäuse eine kreisförmige Isolierstoffplatte in den untern Rand des Metallzylinders ein- rollen oder einwalzen, derart, dass der Rand der Platte in das Gehäuse eingebettet ist.
Der Elektromotor kann nunmehr frei in das Gehäuse hineingestellt und von aussen her mit Schrauben an der Bodenplatte aus Isolier stoff befestigt werden.
In der Zeichnung ist ein Ausführungsbei spiel des Erfindungsgegenstandes dargestellt, und zwar ist hier als Beispiel ein Staub sauger mit zylindrischem Gehäuse gewählt.
a zeigt das Gehäuse aus Aluminium oder dergleichen im Längsschnitt. b ist die Boden platte aus Isolierstoff, die hier in einen Falz c eingesetzt und in diesen durch den äussern vorspringenden Rand d eingerollt und da durch gehalten ist. Die Platte hat in derMitte eine Öffnung zum Durchtritt der Motorwelle bezw. des anzuschliessenden Lagerteils, wäh rend zur Befestigung des Motors an der Platte mittels der Schrauben e entsprechende Löcher vorgesehen sind.
Der Motor steht auf diese Weise frei auf der Bodenplatte und ist somit gegenüber dem Metallgehäuse vollstän dig elektrisch isoliert.
Device with metal housing and electric motor. The housings of electrical devices with an electric motor, for example vacuum cleaners, are usually made of metal, preferably light metal. To ensure that they offer the necessary protection against injury from electrical currents during use, they must be insulated in some way against body contact. So far, the motors were usually fastened in the housing in such a way that they were held with screws on the sides and on the bottom of the housing without being electrically isolated from the housing.
The invention relates to a device with metal housing and electric motor, which is characterized in that the motor is carried by a support device made of electrical Iso lierstoff, expediently from a support plate, which in turn is firmly connected to the housing. In the case of a cylindrical housing, for example, a circular insulating material plate can preferably be rolled or rolled into the lower edge of the metal cylinder in such a way that the edge of the plate is embedded in the housing.
The electric motor can now be freely placed in the housing and fastened from the outside with screws to the base plate made of insulating material.
In the drawing, a Ausführungsbei is shown game of the subject invention, namely a vacuum cleaner with a cylindrical housing is chosen as an example.
a shows the housing made of aluminum or the like in a longitudinal section. b is the bottom plate made of insulating material, which is used here in a fold c and rolled into this by the outer protruding edge d and held there by. The plate has an opening in the middle for the motor shaft to pass through. of the bearing part to be connected, while corresponding holes are provided for fastening the motor to the plate by means of the screws e.
In this way, the motor stands freely on the base plate and is therefore fully electrically isolated from the metal housing.
