Definitions

  • the present invention relates to an extractor device with at least one filter element.
  • a fume extraction device which comprises a blower which is at least partially surrounded by a housing and in which at least one filter element forms at least part of at least one blower blade of the blower.
  • this document describes an axial machine, which can also be referred to as an axial fan, with air-permeable blades.
  • the filter element can comprise both fat filter and odor filter material, for example the fat filter can be mixed with an odor filter material, in particular activated carbon, wetted or otherwise connected.
  • an odor filter element and a grease filter element can be provided in the extractor device.
  • a disadvantage of the known extractor device is that the filter rate on the odor filter element and the fat filter element are different.
  • the flow that flows through the filter element is also referred to as the secondary flow or filter volume flow.
  • the main flow generated by the blower is referred to as the delivery volume flow.
  • the ratio of filter volume flows to the delivery volume flow is referred to as the filter rate.
  • an extractor device which has a housing and a rotor arranged in the housing with at least one rotor blade, which is formed at least in regions by a filter element, the rotor blade comprises at least one fat filter element and at least one odor filter element which are adjacent to one another in the axial direction of the rotor blade, characterized in that the fat filter element is adjacent to the leading edge of the blade and the odor filter element is adjacent to the trailing edge of the rotor blade and the length of the fat filter element is greater than the length of the odor filter element.
  • an extractor device is a device by means of which at least some of the contaminants can be removed from vapors and vapors. Vapors and vapors are also referred to below as polluted air. Liquid and particulate impurities and odorous substances are particularly preferably removed from the vapors and vapors by means of the extractor device according to the invention.
  • the extractor device is understood to mean the entire device by means of which the impurities are removed.
  • the extractor device can be installed in an extractor hood or be configured as an extractor hood.
  • the extractor hood device has at least one housing and a rotor arranged in the housing.
  • the housing and the rotor are also referred to as blowers.
  • the fan particularly preferably represents an axial fan.
  • the housing is an at least partially closed container for influencing the flow in the extractor device.
  • the housing preferably has a cylindrical shape and is open at the top and bottom.
  • the top is also referred to as the clean air side and the bottom as the inflow side.
  • the air to be cleaned is moved by the fan in a direction parallel to the axis of the rotor, which is also referred to as the rotor hub.
  • the housing preferably extends parallel to the rotor hub in a rotationally symmetrical manner around the latter. On the one hand, this prevents the radial escape of air from the fan and, on the other hand, the air is reliably guided in the housing.
  • directional indications relate to an extractor hood device and its components in the assembled state in which one side, in particular the underside of the extractor hood device, faces a cooktop located under the extractor hood device.
  • the rotor comprises at least one rotor blade.
  • the at least one rotor blade is preferably attached to a rotor hub and extends radially outward from the rotor hub.
  • a plurality of rotor blades are preferably provided on the rotor hub. The details of the rotor blades are described below using a rotor blade.
  • the plurality of rotor blades preferably have the same structure.
  • the at least one rotor blade is formed at least in regions by a filter element.
  • the filter elements can be fastened in brackets or on connecting elements. Alternatively, the filter elements can preferably be held in one or more frames.
  • the extractor device is characterized in that the rotor blade comprises at least one grease filter element and at least one odor filter element which are adjacent to one another in the axial direction of the rotor blade.
  • a grease filter element is a filter element that is designed to filter out liquid contaminants, such as grease and other liquids, from the contaminated air.
  • the grease filter element has a certain blockage, via which the air is deflected several times.
  • the heavy particles, in particular fat particles hit the filter material and are separated there.
  • the grease filter element can consist, for example, of one or more expanded metal filters. However, other fat filter elements that function according to the principle of inertia can also be used.
  • the odor filter element preferably consists of a material on which odor substances can separate or on which these can be bound.
  • the odor filter element preferably has activated carbon as the filter material. The vapor must strike the surface of the filter material, in particular the activated carbon, or flow along it. Depending on the structural design, the tightness or the grain size of the activated carbon, the characteristic of the pressure loss in the air flowing through the odor filter element is different.
  • the pressure losses at the grease filter element and the odor filter element are different at the same inflow velocities.
  • the pressure loss at the odor filter element is generally higher than at the fat filter element, the difference increasing with increasing flow velocity. Due to the different pressure losses of the filter media of the Fat filter element and the odor filter element result in different sized secondary flows through the rotor blades with the same filter division, that is, with the same size of the filter area of the different filter elements. This is reflected in different filter rates.
  • the pressure applied to the rotor blade or blades can be higher, in particular in the outflow region of the housing. Since the fat filter element and the odor filter element are adjacent to one another in the axial direction according to the invention, the geometry of the housing can be set such that a higher pressure is applied to the rotor blade in the area in which the odor filter is located.
  • the axially offset arrangement of the odor filter element and the fat filter element enables the filter rate on the individual filter elements to be set in a targeted manner.
  • the grease filter element is adjacent to the leading edge of the blade and the odor filter element is adjacent to the trailing edge of the rotor blade.
  • the leading edge of the blade is the axial end of the rotor blade which faces the upstream side of the housing, in particular the underside of the housing, in the assembled state of the extractor device.
  • the trailing edge is the opposite axial end of the rotor blade, which faces the outflow side and in particular the top of the housing in the assembled state of the extractor device.
  • the grease filter element is thus arranged in the lower area of the rotor blade and fumes and vapors are first passed through these grease filter elements. This removes grease and other liquid contaminants from the contaminated air before it reaches the odor filter element. Contamination, in particular clogging of the odor filter element displaced axially upward by grease or other liquid contaminants can thus be prevented.
  • the rotor blade has a hub ratio di / da in the range from 0.4 to 0.6.
  • the total pressure that can be built up depends on the circumferential speed, i.e. the radius and speed. If the hub ratio is too small, i.e. the inner diameter is small, that is The peripheral speed is also very low and not enough pressure is built up.
  • a sufficiently high total pressure can be built up in the turbomachine.
  • the rotor preferably has a ratio of the length of the rotor blade to the outside diameter of the rotor of greater than 1.
  • the length of the rotor blade is understood in particular to mean the length of the center line of the rotor blade in the axial direction, which can also be referred to as a skeleton line. This length can be greater than the height of the rotor blade, that is to say its axial dimension.
  • the at least one rotor blade represents a twisted blade.
  • a twisted blade is understood in particular to be a blade that extends in a spiral around the rotor hub.
  • the contact surface of the blade on the rotor axis therefore represents a spiral shape or part of a spiral.
  • the rotor blade can extend straight from the rotor axis in the radial direction.
  • the twisted shape of the rotor blade can on the one hand cause the incoming air to swirl around the rotor axis.
  • the passage of air through the rotor blade, in particular through the filter elements in the rotor blade is favored in this form of the rotor blade.
  • the rotor blade can thus have an axial curvature. Additionally or alternatively, the rotor blade can also have a radial curvature.
  • a radial curvature here is a curvature of the blade in the radial direction. The flow against the rotor blade can be further supported by an additional radial curvature.
  • the length of the center line of the rotor blade is greater than the axial height of the rotor blade.
  • the length of the rotor blade is large due to the ratio of the length of the rotor blade to the outer diameter of the rotor, which is preferably greater than 1.
  • a large length of the rotor blades increases the surface area of the blades and thus also the surface of the filter elements. This reduces the speed at which the air has to pass through the filter elements.
  • the ratio of the length of the rotor blade to the outer diameter of the rotor is particularly preferably in the range from 1.2 to 1.5.
  • the degree of reaction of the blade expressed by the ratio of the static pressure increase to the total pressure increase in the fan, is greater than 80%.
  • Static pressure is understood here to mean the pressure difference from the suction to the pressure side of the rotor blade and thus across the filter element.
  • the total pressure is the sum of static pressure and dynamic pressure.
  • the length of the fat filter element is greater than the length of the odor filter element.
  • the length of the filter element is understood to mean the dimension of the respective filter element along the skeleton line of the rotor blade. A larger part of the rotor blade is thus formed by the grease filter element.
  • a greater pressure can prevail in the fume extraction device according to the invention by suitable choice of the geometric dimensions and the degree of reaction in the area of the outflow side of the housing, adequate filtering of odorous substances can nevertheless be ensured, although the area covered by the odor filter is smaller than that Area covered by the grease filter element.
  • the dividing line between the fat filter element and the odor filter element is in the range from 55 to 70% of the length of the rotor blade.
  • the fat filter element and the odor filter element are held in a common frame.
  • the frame can surround the filter elements at their edges.
  • support structures for the respective filter elements are provided in the frame.
  • the extractor device 1 comprises a housing 2 and a rotor 40.
  • the housing 2 together with the rotor 40 forms the fan 4.
  • the housing 2 represents a cylindrical housing.
  • the housing 2 is open at the top and bottom thereof. Air flows through the housing 2, which flows into the fume extraction device 1 in a main flow direction S from below.
  • the underside of the housing 2 and thus the extractor hood device 1 is therefore referred to as the inflow side A and the top side as the clean air side R.
  • an anti-tamper grille 21 is provided in the top and bottom of the housing 2.
  • the lateral surface of the housing 2 is formed in the embodiment shown by a housing wall 23, which forms part of the circumference of the housing 2, and a housing frame 20 and doors 22.

  • the rotor blades 41 have no curvature in the radial direction.
  • the fat filter element 30 is arranged in the lower region of the rotor blade 41, that is to say forms the lower part of the rotor blade 41.
  • the odor filter element 31 is arranged in the upper region of the rotor blade 41, that is to say forms the upper part of the rotor blade.
