Definitions

  • the present invention relates to a fan housing for an extractor device, a fan for an extractor device and an extractor device with such a fan.
  • blowers are used, through which the vapors and vapors are sucked into the extractor device.
  • the blower can also be referred to as a fan.
  • radial fans which can also be referred to as radial fans, are preferably used as fans.
  • Radial blowers/fans with forward-curved blades of the fan wheel are particularly preferred.
  • This type of radial blower/radial fan is particularly preferred because of its good acoustic properties and the very compact design.
  • Centrifugal blowers/fans consist of a spiral housing in which the fan wheel is accommodated.
  • the volute casing has an outlet, on which a flange is usually provided for attachment to a piping downstream of the blower/fan in the direction of flow.
  • the necessary flange takes up space here.
  • the object of the present invention to provide a solution by means of which a blower can be provided flexibly in a fume extraction device while requiring as little installation space as possible.
  • the invention is based on the finding that this object can be achieved in that the housing of the fan is constructed in two parts and one housing part comprises at least part of the outlet of the fan.
  • the invention therefore relates to a fan housing for a vapor extraction device, which has a housing body and an outlet element, the housing body serving to accommodate a fan wheel, the outlet element extending outwards over the outer circumference of the housing body and at the end of the outlet element, which faces away from the housing body, the air outlet opening of the fan housing is provided.
  • the fan housing is characterized in that the fan housing consists of a first housing part and a second housing part, the parting plane between the two housing parts being parallel to a plane in which the central axis of the housing body lies, and the parting plane between the central axis and the air outlet opening of the Blower housing is located and the second housing part forms at least part of the outlet element.
  • the fan can also be referred to as a fan and the centrifugal fan can be referred to as a centrifugal fan.
  • the fan housing can also be referred to as a fan housing. In the following, however, the terms fan, fan housing and centrifugal fan are used.
  • the extractor device in which the fan housing can be used can represent, for example, an extractor hood or a table fan.
  • the fan housing is the housing in which the fan wheel of the fan is accommodated and through which the air sucked in by the fan wheel is guided.
  • the fan is preferably a radial fan and the fan housing is also referred to as a volute housing.
  • the fan housing has a housing body and an outlet member.
  • the housing body can also be referred to as a housing body area or spiral, and the outlet element as an outlet nozzle or outlet nozzle area.
  • the housing body serves to accommodate the fan wheel of the blower. In particular, an accommodating space with a round or spiral cross section is formed in the housing body.
  • the outlet member is a duct member that extends between the case body and the air outlet port of the fan case.
  • the outlet element extends outwards over the outer circumference of the housing body.
  • the outlet element extends beyond the outer circumference in a direction that deviates from the radial direction.
  • the outlet element is preferably inclined to the radial direction of the housing body in such a way that the angle between the radial direction and the extent of the outlet element is greater than zero and less than or equal to 90°.
  • the outlet element preferably extends in the tangential direction of the housing body.
  • the air outlet opening of the fan housing is provided at the end of the outlet element that faces away from the housing body.
  • the air outlet opening is the opening through which air leaves the blower housing. Further piping of the extractor device can be connected to the air outlet opening, via which the air is routed before it leaves the extractor device.
  • the fan housing consists of a first and a second housing part.
  • the two housing parts are separated from each other by a parting line.
  • the dividing line between the two housing parts is parallel to a plane in which the central axis of the housing body lies.
  • the parting line is between the central axis of the housing body and the air outlet opening of the fan housing.
  • the second housing part forms at least part of the outlet element.
  • the first housing part forms at least part of the housing body of the fan housing.
  • the fan housing consists of two housing parts, one of which—the second—forms at least part of the outlet element
  • the fan housing a modular structure.
  • This structure facilitates the integration of the blower into different fume extraction devices.
  • the second housing part which comprises at least part of the outlet connection piece, can have the geometry of the outlet connection piece required for the special vapor extraction device.
  • the cross section of the air outlet opening and/or the alignment of the outlet element can be adapted to the geometry of the extractor hood and the second housing part can be selected accordingly.
  • the transition between the housing body and the outlet element forms a nose at one end in the circumferential direction, and the parting plane between the two housing parts lies between the nose and the air outlet opening.
  • the nose can also be called the tongue.
  • At the transition between the housing body and the outlet element there is an opening through which air can pass from the housing body into the outlet element.
  • a nose is formed at one end of the transition and particularly the circumferential opening due to the orientation of the outlet member.
  • the nose lies at the end of the opening where the angle between the tangent of the circumference of the housing body and the extension of the outlet member is an acute angle.
  • the second housing part comprises only part of the outlet element.
  • the further part of the outlet element is formed on the first housing part.
  • only the area of the outlet element on which the air outlet opening is provided can be specifically selected according to the geometries of the vapor extraction device, while the first housing part can remain unchanged for different vapor extraction devices.
  • the number of different housing parts that have to be provided for different fume extraction devices is therefore small and storage is therefore simplified.
  • the transition between the housing body and the outlet element forms a nose at one end in the circumferential direction and the parting plane lies between the nose and the central axis of the fan housing.
  • the entire outlet element is contained in the second housing part.
  • the outlet element forms the second housing part. In this case, the housing part can be attached to the transition between the housing body and the outlet element.
  • the housing parts are preferably detachably connected to one another.
  • the detachable connection can be formed, for example, by a plug-in connection, snap-in connection or clip connection. The fact that the housing parts can be detached from one another further simplifies flexibility.
  • connection of the housing parts can optionally be designed in such a way that the fan can be suspended from the outlet element.
  • this can be fixed, for example, to the first housing part on the extractor device and the connection between the first and the second housing part only has to absorb the operating loads.
  • the cross section of the air outlet opening can be round or square.
  • the shape of the passage opening, which lies between the first and the second housing part, is independent of the shape of the air outlet opening.
  • a round air outlet opening can be provided on the second housing part and this can thus be adapted to the geometry of the vapor extraction device in which the housing housing is to be used, without making an adapter necessary.
  • the second housing part in which the air outlet opening is provided, consists at least partially of an acoustically damping material.
  • the housing part consists of acoustically damping material, no further noise-damping part is necessary for this purpose and the structure of the fan housing can be further simplified as a result.
  • the second housing part can assume the function of a muffler directly at the source of the noise, namely the fan.
  • the second housing part, in which the air outlet opening is provided consists at least partially of an acoustically permeable material. This embodiment is particularly advantageous when the fan is installed in an environment where a separate acoustic enclosure is provided. This is because the sound emission can be minimized in this case, since the sound is no longer reflected along the walls of the housing part and is thus transported out of the blower via the air outlet opening.
  • the outlet element has a fold.
  • a chamfer is a geometry in which at least one wall of the outlet element extends at least in regions in a direction that is inclined to the longitudinal extension of the outlet element.
  • the fold can create a transition between the geometry of the passage opening and the geometry of the air outlet opening.
  • the fold can also create a difference between the alignment of the passage opening and the alignment of the air outlet opening.
  • the air outlet opening can be offset by 90° relative to the passage opening.
  • an electronics housing which can also be referred to as an electronics box or E-box, is provided on the second housing part on which the air outlet opening is provided.
  • the second housing part, including the electronics housing, can then preferably be used as a supporting unit.
  • fastening means for fastening the fan housing to the fume extraction device are therefore provided on the electronics housing.
  • the invention also relates to a fan that has a fan housing according to the invention.
  • the invention relates to an extractor device which is characterized in that it has at least one fan housing according to the invention.
  • the advantages and features that are described in relation to the fan housing apply--insofar as they are applicable--to the extractor device according to the invention and the fan, and vice versa.
