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 and a blowing side, and

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

a cover arrangement positioned on the suction side in such a way that a part of the suction side is covered, wherein the cover arrangement is provided with at least one opening for connecting to a respective suction hose.

2. A device according to claim 1, wherein the cover arrangement covers about 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 the fan housing is formed as a winding drum for the suction hose.

6. A device according to claim 1, wherein each suction hose is affixed to the cover arrangement (30;

40) with a snap closure.

7. A device according to claim 1, wherein the cover arrangement comprises at least two cover parts to each of which a suction hose is connectable via an associated opening.

8. A device according to claim 7, wherein the cover parts can respectively be affixed in a same pitch angle distance from each other.

9. A device according to claim 7, wherein there are provided two cover parts laterally affixed horizontally opposed to each other.

10. A device according to claim 7, wherein there are provided three cover parts, one cover part of which affixed at the bottom and the two other cover parts laterally affixed horizontally opposed to each other.

11. A device according to claim 7, wherein the cover parts are each formed as ring segments, the motor being arranged in a casing which defines the interior limitation of the ring segments.

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