Abstract: The invention relates to an impeller receptacle, in particular for an impeller of a fan, comprising at least one rotationally symmetrical body. The rotationally symmetrical body has a first end face, a second end face and a lateral face, wherein at least one radial bore extends radially from the lateral face into the rotationally symmetrical body and an assembly recess extends from the first end face into the radial bore. A detent ball having a ball diameter and a spring are arranged in the at least one radial bore, wherein the detent ball can be pressed radially outwards by means of the spring. The radial bore has at least one first, inner radial bore diameter and a second, outer radial bore diameter, the second, outer radial bore diameter being smaller than the ball diameter.

Abstract: A device for extracting vapors comprising an intake housing and a blower, wherein the intake housing comprises an air inlet means, wherein the air inlet means has an upper wall and a lower wall which form an interior space with an inlet opening, wherein at least the upper wall has a corrugated shape on an inner side with at least two upwardly curved surface sections, wherein at least in the region of the upwardly curved surface sections the interior space has widenings.

Abstract: The invention relates to an extractor device comprising a centrifugal blower (16) as an extraction fan (6), with an upwards suction opening (14) facing the hob (8), around which an annular space (20) is formed. The first air-guiding channel (10) flows into the suction opening (14) of the centrifugal blower (16). The annular space (20) comprises a side wall (22) by means of which the discharge air flow leaving the centrifugal blower (16) is deflected. A collecting vessel (24) is embodied in a second plane below the centrifugal blower (16), for collecting particles bounding off the side wall (22), and the discharge air flow flows out of the annular space (2) in a second air-guiding channel (28) out of the extraction fan (6).

Abstract: The invention relates to an air extraction device (2) comprising an intake opening (4), a downstream air duct for an air flow (L), said air duct extending in a first section through a rotatingly driven fan wheel (6) radially outward and extending in a second section downstream of the outlet openings (5) of the fan wheel (6) such that the air flow (L) is deviated in an approximately axial direction to the fan wheel (6), and runs into an exhaust opening (8). The second section has a lateral wall (10) that is arranged opposite to the outlet openings (5) of the fan wheel (6) at a distance thereto. The aim of the invention is to improve the capacity of the air extraction device. For this purpose, the second section comprises a through-flow compartment (12) arranged in the plane of rotation of the fan wheel (6) which compartment is arranged downstream of the outlet openings (5) of the fan wheel (6), which is radially limited by the lateral wall (10) and in which no air guideways are arranged.

Abstract: The present invention relates to a fume extraction hood (2) having an exhaust opening (4) for leading away exhaust air (A) and an inlet opening (6) for feeding inlet air (Z), disposed adjacent to the exhaust opening (4). In order to achieve an inlet air guide, by means of which cooking vapors can be effectively captured and fed to the exhaust opening, the invention proposes that the inlet opening (6) is disposed and implemented so that the inlet air flow (8) flowing out of the inlet opening (6) in a direction oriented opposite to the flow direction of an exhaust gas flow (10) flowing into the exhaust opening (4), and the exhaust air flow (10) is deflected sideways via an extraction path (F).

Abstract: An exhaust hood having a first fan wheel sucking in and transporting away room air. A second fan wheel sucks in external air and is arranged axially displaced relative to the first fan wheel. Guide vanes are arranged externally about the first and second fan wheels. The guide vanes are embodied as a cavity and form venting passages. A first air flow exiting from the first fan wheel and a second air flow exiting from the second fan wheel are guided past each other, separate from each other, through the guide vanes and are directionally deflected by the guide vanes. Walls of the guide vanes form a surface for heat exchange between the first and second air flows.

Abstract: A device for removing suspended particles from an airflow has an intake opening, an air conveying the duct, and a fan. The air conveying duct deflects the airflow with regard to its flow direction at least sectionally. In order to filter the suspended particles almost completely from the air, the airflow is guided in the air conveying duct by positive guiding elements along a general conveying direction such that the airflow is subjected to at least a twofold sequentially arranged curve-shaped deflection in different directions. The height of at least one positive guiding element projecting into the air conveying duct is smaller than the free height of the flow cross-section of the air conveying duct in the area of the positive guiding element.
