Definitions

  • the present invention relates to a fan for an extractor device and a combination device with at least one extractor device.
  • Combination devices are known in which a hob, for example an electric, induction or gas hob, is combined with an extractor device, which can also be referred to as table ventilation. These combination devices are usually integrated into pieces of furniture, in particular base cabinets in kitchen units. Due to the structural limitations imposed by the furniture, the combination devices must be designed as compact as possible.
  • the blower which can also be referred to as a fan
  • filters in particular grease filters and odor filters, of the extractor device must be integrated in the installation space in the combination device.
  • the grease filters are usually designed as expanded metal filters, through which the grease is filtered out of the air sucked in.
  • the maximum width and depth of the combination device is specified by the standard dimensions of the furniture industry.
  • the available installation space is also limited in terms of height, since storage space, in particular space for drawers, is usually provided underneath the combination device and should be as large as possible, i.e. the combination device should intervene as little as possible in this storage space.
  • the fan of an extractor device in particular an extractor device of a combination device, generally comprises a motor by means of which a fan wheel is driven.
  • the axis of the motor and thus also of the fan wheel is usually vertical when installed.
  • the fan wheel is surrounded by a housing, which is also referred to as the fan housing.
  • the housing preferably has a spiral shape and the housing is therefore also referred to as a spiral housing.
  • the housing serves as an air guide in the fan to an air outlet.
  • the object of the present invention is to create a solution by means of which the available installation space for a fan can be optimally used and in which the extractor device can nevertheless be operated reliably.
  • the object is achieved by a fan for an extractor device comprising a fan wheel, a motor and a housing, the fan wheel having blades on its outer circumference which extend parallel to the axis of the fan wheel, the housing has a spiral shape and at least one air inlet opening is provided on at least one axial side of the housing and an air outlet is provided on the radial circumference of the housing.
  • the blower is characterized in that the housing has a lower height in an area lying radially on the outside of the air inlet opening than at the air inlet opening.
  • the blower can also be referred to as a fan or fan.
  • the fan represents a fan for an extractor device.
  • a device is referred to as an extractor device by means of which contaminated air can be sucked in and cleaned.
  • the fan includes a fan, a motor and a housing. According to the invention, it is also possible for the fan to have several fan wheels and / or several motors. The invention is described below with reference to a fan with a fan wheel and a motor.
  • the fan wheel can also be referred to as an impeller.
  • the fan wheel has blades on its outer circumference, which are also referred to as rotor blades. The blades can extend radially at least partially inwards or outwards from the outer circumference of the fan wheel.
  • the blades are arranged on the fan wheel in such a way that they extend parallel to the axis of the fan wheel.
  • the motor via which the fan wheel is driven is preferably located in the axis of the fan wheel.
  • the axis of the fan wheel therefore usually corresponds to the axis of the motor and is also referred to as such.
  • the blades extend in the direction parallel to this axis.
  • the blades can have a shape that is inclined to the parallel. In this case, the main direction of the blades is understood as the parallel extension.
  • the blades have a curved cross section for their function.
  • the housing has a spiral shape.
  • the outer circumference of the cross section of the housing perpendicular to the axis of the fan wheel corresponds to a logarithmic spiral.
  • At least one air inlet opening is provided in at least one axial side of the housing.
  • Axial sides are the sides that form the top or bottom of the housing in the axial direction of the motor.
  • An air inlet opening is preferably provided in the upper side of the housing.
  • the axis of the motor lies in the air inlet opening, that is to say that the air inlet opening is introduced in the center of the axial side.
  • An air inlet opening is an opening through which air can be sucked into the interior of the housing.
  • the housing has an air outlet which is provided on the radial circumference of the housing.
  • the air outlet is preferably formed by a nozzle which forms the end of the spiral shape.
  • the air outlet can also be referred to as a pressure port.
  • the blower is characterized in that the housing has a lower height in an area offset radially outward from the air inlet opening than at the air inlet opening.
  • Directional information such as above and below, relate, unless otherwise stated, to a fan in the state installed in an extractor device.
  • the dimension in the axial direction is understood as height.
  • the width is the dimension perpendicular to the height.
  • the direction perpendicular to the axis of the motor is called radial.
  • the area of the housing in which it has a lower height is also referred to as a flat area or an area of lower height.
  • the flat area preferably has a constant height.
  • the performance of the fan is determined by the geometry of the housing, in particular by the height, the width and the shape of the development of the spiral shape.
  • the housing has so far been designed according to rules and empirical values that dictate the construction of the housing.
  • the height of the housing and the width, that is to say the diameter, of the housing have an influence on the performance of the fan.
  • the height is determined by the height of the fan wheel, in particular the blades, the protrusion of the housing over the fan wheel upwards, i.e. in the direction of the air inlet opening and the protrusion downwards, i.e. the protrusion of the housing over the fan wheel in the direction in which the motor is introduced into the housing, determined.
  • These dimensions are in Figure 8 shown schematically on the basis of a conventional fan.
  • the height of the fan wheel cannot be reduced because this height is specified.
  • the housing having a lower height in an area radially outside the air inlet opening.
  • a space with a small height can be taken into account.
  • the fan can be installed in an installation space that is, for example, 15 to 30 cm high.
  • the outer area, in which the height of the housing is lower further components of the fan or another part of a combination device, in particular the hob, can be accommodated with the fan according to the invention without the height of the installation space having to be increased.
  • the height of the housing in the flat area can for example be 1 to 5 cm less than at the air inlet opening.
  • the height of the housing at the air inlet opening can be 10 to 25 cm, for example.
  • the transition from the greatest to the lowest height lies in the radial area in which the blades of the fan wheel are located.
  • the height of the housing decreases over at least part of the radial extent of the blades.
  • the low-height region of the casing begins at the radially outer end of the blades.
  • the area of lower height can extend to the outer radial circumference of the housing.
  • the area of the lower height is therefore radially outside the fan wheel.
  • the required height for the blades of the fan wheel can be provided in the area of the air inlet opening.
  • the height of the blades cannot be changed.
  • the reduction in height is produced by a recess on the top and / or the bottom of the housing.
  • the recess is formed by a shoulder in the wall of the housing, which is the top or bottom.
  • the return extends over the entire scope of the Air inlet opening, which is preferably circular.
  • the recess is preferably rounded at least in the interior of the housing; does not form any sharp edges.
  • the recess can only be provided on the top or the bottom of the housing. Preferably, however, a recess is provided on both the top and the bottom of the housing. The height of the housing is thus decreased from above and below.
  • the recess on the top is preferably larger than the recess on the underside.
  • the air inlet opening is preferably made in the top of the housing.
  • the air inlet opening is usually increasingly sucked by the fan wheel to the bottom of the housing.
  • This creates a dead space in which there is no flow in the area of the fan wheel facing the upper side, that is to say in the upper area of the housing. In this dead space, therefore, no space has to be made available inside the housing outside the fan wheel in order to be able to ensure sufficient suction of air by the fan.
  • the recess i.e. the reduction in height, is chosen to be greater in the upper area of the housing than in the lower area, this does not impair the flow behavior in the housing and can still create additional space for further components around the housing to serve.
  • the recess at the top is greater than the axial distance between the air inlet opening and the axial edge of the blades which faces the air inlet opening. This means that the recess at the top surrounds the upper part of the blades radially.
  • the cross-sectional area formed by the region of lesser height, along a cutting plane in which the axis of the motor lies corresponds to a cross-sectional area which is present with the same maximum height.
  • This cross-sectional area which is located radially outside the fan wheel in the housing, influences the volume flow in the fan and thus also the performance of the fan. The preferred design of this cross-sectional area can ensure that the performance of the fan is not impaired.
  • the cross-sectional area formed by the region of lesser height, along a cutting plane in which the axis of the motor lies is at least the same size as the cross-sectional area that is present with the same maximum height.
  • the cross-sectional area formed by the region of lower height along a cutting plane in which the axis of the motor lies is even larger than the cross-sectional area that would be present in this cutting plane if the greatest height remained the same.
  • the width of the housing is therefore increased.
  • the size of the housing perpendicular to the axial direction is increased.
  • the width is increased compared to a housing which is designed for a performance with a constant maximum height.
  • the installation space in kitchen furniture and combination devices there are also restrictions with regard to the installation space in kitchen furniture and combination devices.
  • the part of the kitchen furniture in which an extractor device or a combination device is installed cannot be used for any other purpose on the sides and this installation space can therefore be optimally used due to the increased width and at the same time the performance of a blower according to the invention with a partially reduced height can be increased.
  • an air guide wall is formed on the air inlet opening which extends radially and axially into the interior of the fan.
  • the air guide wall is preferably curved convexly inward from the air inlet opening.
  • the air guide wall is particularly preferably designed in one piece with the further housing.
  • the air baffle can also be called a pavilion.

  • the axial distance between the inner end of the air guide wall and the air inlet opening is greater than the axial distance between the air inlet opening and the axial edge of the blades facing it.
  • the air guide wall is immersed in the fan wheel, in particular in the blades arranged in a ring on it.
  • the upper area of the housing near the air inlet opening is usually a dead space. The immersion of the air baffle in this area therefore does not hinder the flow. Nevertheless, by dipping the air guide wall, a sufficiently long air guide wall can be used without increasing the height of the housing.
  • the angle section can be 45 °, for example.
  • the spiral course can be determined using the radii of the spiral calculated in this way.
  • the housing is preferably made of plastic.
  • reinforcing struts can be provided on at least one axial side of the housing in the region of the lower height of the fan. This ensures sufficient stability of the housing without it taking up additional installation space.
  • At least one component, in particular an electronic component, of the fan can be arranged in the area of lower height on at least one axial side of the housing.
  • the space requirement is also minimized in this embodiment.
  • other components for example parts of the cooktop, can also be arranged in the area of lower height.
  • the invention relates to a combination device comprising at least one fan according to the invention.
  • the combination device comprises a hob and an extractor device with at least one fan arranged below the hob.
  • One of the at least one air inlet opening faces upwards.
  • a recess is provided in the hob or adjacent to the hob through which air can be drawn in downwards by the fan. Since the air inlet opening is directed upwards, reliable suction of contaminated air from the space above the hob can be guaranteed. Since, according to the invention, the height of the housing of the fan is greater at the air inlet opening, inadvertent entry of water or other liquids into the housing and thus into the fan can be prevented.
