Abstract

The invention relates to a simple hollow space, in particular a channel, a cellar or a living room, aerating device (10) comprising several paddles (12) which are fixed to a hub (14) and surrounded by a fan housing (16) provided with input and output (17, 18) sides and a motor (20) which is mounted on the axis of rotation (15) of the hub (14) for driving the hub (14) and the paddles (12). According to said invention, a cover arrangement (30; 40) can be positioned on the output side (17) in such a way that a part thereof is covered, wherein said cover arrangement (30; 40) is provided with at least one opening (34-36; 44, 45) for connecting to a respective discharge hose (37-39; 47, 48).

Claims

1. A device for venting a cavity, in particular a cellar or a dwelling-room, comprising:

fan blades which are fixed to a hub and surrounded by a fan housing provided with a suction side having a suction opening and a blowing side;

a motor located in the region of the axis of rotation of the hub for driving the hub and the fan blades; and

,

a suction side cover arrangement comprising at least two cover plates formed as truncated wedge-shaped ring segments having a space between adjacent cover plates, the cover plates having a suction hose connectable via an associated opening, wherein the motor is arranged in a casing defining an inner boundary of the ring segments, and

wherein the motor is capable of being cooled by air drawn through the spaces between the cover plates.

2. A device according to claim 1, wherein the cover arrangement covers 20 to 80% of the surface on the suction side.

3. A device according to claim 1, wherein the cover arrangement is affixed to the fan housing with a snap closure.

4. A device according to claim 1, wherein the cover arrangement is hinged to the fan housing.

5. A device according to claim 1, wherein each suction hose is affixed to the cover arrangement with a snap closure.

6. A device according to claim 1, wherein the cover plates are affixed in a same pitch angle distance from each other.

7. A device according to claim 1, wherein the cover arrangement comprises two cover plates laterally affixed horizontally opposed to each other.

8. A device according to claim 1, wherein the cover arrangement comprises three cover plates, one cover plate affixed at a bottom portion on the suction side and the two other cover plates laterally affixed horizontally opposed to each other.

9. A device according to claim 1, wherein the fan blades in the fan housing are formed as an axial-flow fan.
