Definitions

  • the present invention relates to an extractor hood.
  • the air extracted from extractor hoods for example above a cooking stove, is loaded with impurities such as water, fat, oil and the like.
  • Extractor hoods are known in which the air to be cleaned is sucked into the extractor hood via an edge gap.
  • An extractor device with edge suction is, for example, in EP 2 772 695 A1 described.
  • JP 2005 214584A describes an extractor hood in which a fan is arranged above a housing. Air is sucked into the housing via the blower. In addition, an auxiliary fan is provided adjacent to the fan through which air is discharged across the housing in the form of an air curtain.
  • JP2005098618A discloses an extractor hood in which, in addition to the extractor hood fan, an additional fan is arranged at the front edge of the extractor hood, via which an air curtain is output in the horizontal direction.
  • EP1757870A2 discloses a fume hood with a nozzle assembly at the front edge of the hood. Air is discharged onto a curved surface via the nozzles to discharge air downwards and backwards.
  • an extractor hood which has a first and a second housing.
  • a hood is accommodated in the first housing.
  • an insertion opening is provided, into which a cover part is inserted.
  • Inlet areas are formed in the cover part.
  • Air is conducted via the hood to an intake opening, behind which a fan is arranged.
  • the range hood has an exhaust opening for discharging a laminar flow of air along the inner wall surface offset upwards from the inlet area.
  • the blow-out opening is formed by a distance between the inner wall and a wall area of the housing, which extends upwards from the insertion opening.
  • the blow-off opening is connected to the exhaust air duct provided on a second housing via air supply ducts.
  • a disadvantage of this extractor hood is that it has a complex structure.
  • the WO 2015/166947 A discloses the features of the preamble of claim 1.
  • the object of the present invention is therefore to provide an extractor hood in which, with a simple structure, the deposition of particles on the extractor hood is reduced.
  • top and bottom or top and bottom relate to an extractor hood with a flow channel arranged horizontally in the extractor hood and parts thereof.
  • an extractor hood is preferably referred to as an extractor hood which can be used in the household, in particular in a kitchen, for removal and cleaning of cooking fumes, also known as vapors.
  • the extractor hood represents, for example, a ceiling-mounted or a wall-mounted extractor hood.
  • the extractor hood has a housing that can also be referred to as a viewing hood. There is a suction opening in the underside of the housing.
  • the housing forms at least part of a flow chamber.
  • the fan of the extractor hood which is also referred to as a fan, is preferably arranged in the flow space.
  • a negative pressure is generated by the blower, which is used to suck in contaminated air from around and in particular from below the extractor hood.
  • the polluted air also known as fumes, can enter the extractor hood through the suction opening located on the underside of the housing.
  • the extractor hood has at least one filter element on which the contaminated air can be cleaned.
  • the at least one filter element is preferably a filter element for filtering out particles, in particular fat, oil or water particles.
  • the filter element is preferably a flat element, one surface of which is used at least partially for the intake of contaminated air into the filter material. According to the invention, for example, expanded metal can be used as the filter material.
  • the filter element is preferably accommodated in a frame.
  • the frame can also be used to attach the filter element in the extractor hood.
  • the at least one filter element is preferably detachably arranged in the extractor hood and in particular in the housing.
  • the filter element is preferably a filter cassette and is also referred to as a grease filter.
  • the extractor hood includes a baffle plate.
  • the baffle plate represents an airtight component, which is preferably a disc or plate.
  • the baffle plate is arranged in or below the intake opening of the hood housing.
  • the baffle plate also serves as a deflection element, which prevents the uncontrolled and direct, ie immediate, flow of vapors flowing from below to the extractor hood onto the at least one filter element.
  • the baffle plate therefore preferably covers an area that is larger than the area of the filter element or, in the case of a plurality of filter elements, the filter elements.
  • the baffle plate preferably has a size that is smaller than the size of the suction opening of the housing. A gap is thus formed between the underside of the housing and the edge of the baffle plate, which is also referred to as the edge suction gap or edge suction area.
  • the housing forms at least part of a flow space.
  • the flow space includes a flow channel.
  • the area of the extractor hood is referred to as a flow channel that lies between the edge suction area and the at least one filter element provided in the housing.
  • the flow channel is particularly preferably delimited by the housing and the baffle plate.
  • the housing delimits the flow channel to the sides and to the top, and the baffle plate delimits the flow channel to the bottom. The housing thus at least partially forms the flow channel of the flow space of the extractor hood.
  • the vapor is directed to the at least one filter element within the extractor hood and in particular within the housing.
  • the flow channel includes an edge suction area.
  • the edge extraction area is defined by the gap between the housing and the baffle plate.
  • a web or other connecting means can be provided in the edge extraction area.
  • the part of the edge suction area that is permeable to air, that is, in which there are no webs, for example, is referred to as the entry opening of the edge suction area.
  • the entire edge extraction area to form the entry opening, so that fumes can enter the interior of the extractor hood over the entire edge extraction area. Since the edge suction area forms part of the flow channel, the vapor can thus enter the flow channel.
  • the flow channel preferably extends from the inlet opening of the edge suction area to the at least one filter element.
  • At least one deflection point is formed in the flow channel.
  • a point in the flow channel at which the direction of flow of the vapor in the flow channel is changed is referred to as a deflection point.
  • the deflection point is determined by the geometry of the flow channel itself.
  • the geometry of the flow channel depends on the geometry of the housing in interaction with the baffle plate.
  • these changes in direction are not caused by the geometry of the flow channel and therefore do not represent a deflection point within the meaning of the invention.
  • an air supply opening is provided in the area of at least one deflection point.
  • the air supply opening is particularly preferably provided on the flow channel in the area which is located at the deflection point or downstream of the deflection point in the direction of flow.
  • At the deflection point there can be a corner or a curvature of the housing, which causes the change in direction of the vapor flow.
  • the air supply opening is a recess.
  • the air supply opening is a hole or a slit.
  • the shape of the hole or the slot can be chosen freely.
  • more than one air supply opening can also be provided in the area of the deflection point of the flow channel.
  • the air which enters the flow channel through the air supply opening can be exhaust air or ambient air.
  • the vapor flow is advantageously influenced by the entry of air into the flow channel. Due to the entry of the air in the area of the deflection point of the flow channel, the vapor is deflected more effectively than in the devices that are known in the prior art and is thus guided to the filter element. Furthermore, the air that has entered through the air supply opening captures particles from the vapor passing by and thus also prevents the particles from being deposited in the flow channel and in particular on the housing of the extractor hood. This improves the grease label of the cooker hood overall. Furthermore, the deposit of visible grease in the intake area is avoided, thus increasing customer satisfaction. Another advantage is that the formation of accumulations of fat is avoided in an area from which the fat could drip down through the inlet opening of the extractor hood and onto the cooker.
  • the air supply opening is arranged at a distance from the inlet opening of the edge extraction area. Spaced within the meaning of the present invention means that the air supply opening and the inlet opening are not arranged in the immediate vicinity of one another and therefore have no points of contact.
  • the advantage of this embodiment is that the vapor first enters the flow channel via the inlet opening before it is influenced by the air that enters the flow channel through the air supply opening. In this way, account can be taken of the distance that the vapor, which has passed through the entry opening of the edge suction area, travels to the deflection point in the flow channel. Accordingly, it is ensured that the vapor is only influenced by the air that has entered in the area of the deflection point and not already, for example, when the vapor enters the flow channel.
  • the flow space includes an exhaust air duct.
  • the exhaust duct can be a pipe or duct that is perpendicular or parallel to the flow duct.
  • the area of the extractor hood is referred to as the exhaust air duct, which adjoins the filter element in the direction of flow.
  • the fan of the extractor hood is arranged in the exhaust air duct.
  • the exhaust air duct has an outlet opening through which the exhaust air can be discharged to the outside.
  • the exhaust air can be discharged into the room in which the extractor hood is operated or outside the building in which the extractor hood is operated.
  • the exhaust air duct can be formed at least partially by the housing of the extractor hood.
  • the exhaust air duct can also be formed by a separate component, for example a pipe, which can be covered with a fireplace, for example by a chimney.
  • the air supply opening is a bypass between the exhaust air duct and the flow duct.
  • the bypass fluidically connects the exhaust air duct to the flow duct.
  • part of the exhaust air can be routed from the exhaust air duct into the flow duct via the bypass. Because the bypass the air supply opening forms, the exhaust air is introduced into the flow channel in the area of the deflection point.
  • the bypass can be realized by a separate component, for example a tube.
  • the exhaust air duct is arranged above the flow duct and is adjacent to it.
  • the flow duct and the exhaust air duct particularly preferably run parallel at least in regions and have at least one contact point.
  • at least part of the flow duct lies horizontally and the exhaust air duct lies against the horizontal part of the flow duct.
  • the exhaust air duct therefore runs horizontally and the outlet opening of the extractor hood is preferably provided on the side of the extractor hood.
  • the exhaust air duct and the flow duct are separated from one another by a partition.
  • the intermediate wall is a flat component and is preferably a plate or sheet metal.
  • the intermediate wall can consist of sheet metal material, in particular stainless steel sheet metal.
  • the advantages of the present invention can be used particularly easily.
  • the distance between the exhaust air duct and the flow duct is only given by the intermediate wall.
  • the partition divides the flow space into two areas, namely the exhaust air duct and the flow duct.
  • the intermediate wall forms the top of the flow duct and the bottom of the exhaust air duct.
  • the exhaust duct is at this Embodiment limited upwards by the top of the housing.
  • the intermediate wall can be part of the housing or can be introduced into the housing as a separate component.
  • the air supply opening is arranged in the intermediate wall.
  • the air supply opening serves as a bypass between the exhaust air duct and the flow duct.
  • the air supply opening is provided as a recess in the form of a hole or slot in the intermediate wall.
  • the air supply opening is made in the material of the intermediate wall, for example by punching or lasering.
  • the advantage of the arrangement of the air supply opening in the intermediate wall is that a defined connection between the exhaust air duct and the flow duct can thereby be established in a simple manner.
  • the exhaust air in the exhaust air duct can be discharged outwards in the horizontal direction by the fan and the flow of vapor in the flow duct can be directed in the horizontal direction to the filter element.
  • the part of the exhaust air that enters the flow duct via the air supply opening thus preferably enters the flow duct in the vertical direction through the air supply opening.
  • part of the exhaust air can be introduced back into the flow duct in a targeted manner and can thus influence the vapors. Due to the pressure differences between the exhaust air duct and the flow duct, the entry of part of the exhaust air into the flow duct is promoted. This part of the exhaust air, which serves as supply air, generates a flow that can capture particles passing by in the vapor and thus prevent these particles from being deposited on the partition wall or the housing. At least the separation of particles is reduced. This improves the grease label of the extractor hood overall and lengthens the cleaning intervals. Furthermore, fewer particles are separated in the visible range, thus increasing customer satisfaction. Furthermore, the energy efficiency of the extractor hood is increased by using part of the exhaust air.
  • the air supply opening is designed as an air scoop.
  • An air supply opening is referred to as an air scoop, on the inlet side of which an air guiding element is arranged. Air from a flow along the air scoop is guided in a targeted manner to the air supply opening via the air guiding element. Since the air supply opening represents an air scoop, the supply of air to the flow channel in the area of the deflection point is promoted and the accumulation of particles is thus reduced or completely prevented.
  • the air scoop can be provided on an outer wall of the housing and can direct part of the ambient air into the flow channel. According to a preferred embodiment, however, the air scoop is formed between the exhaust air duct and the flow duct and is machined from the material of the intermediate wall.
  • the air scoop is worked out of the material of the partition wall, for example, by cutting, lasering or punching an opening or a slot in the material of the partition wall, which is usually sheet metal, and then the material in the area of the opening or slot is bent upwards.
  • the exhaust air duct is preferably located above the flow duct and in particular above the intermediate wall, the material bent upwards protrudes into the exhaust air duct.
  • the areas of the processed material of the intermediate wall that are bent upwards form projections that can have a tab-like shape. The tab is aligned in such a way that it is directed against the direction of flow of the exhaust air in the exhaust air duct and thus part of the exhaust air is captured by the air scoop and guided into the air supply opening.
  • the advantage of this embodiment is that the air scoop can be manufactured in a simple manner and enables a reliable supply of exhaust air into the flow channel.
  • At least one of the filter elements is accommodated in the intermediate wall between the exhaust air duct and the flow duct.
  • a filter element that is surrounded by the intermediate wall is referred to as being received within the meaning of the present invention.
  • the outer edge of the intermediate wall in perpendicular projection onto the filter element lies outside the edge of the flat filter element, that is, the surface of the filter element is surrounded by the inner edge of the intermediate wall in perpendicular projection.
  • the intermediate wall extends laterally, forwardly and rearwardly beyond the edges of the filter element. The intermediate wall thus forms a flat frame around the flat filter element.
  • the advantage of this embodiment is that a separate filter holder is not required.
  • the filter element below the intermediate wall or on the intermediate wall.
  • the intermediate wall has a passage opening that is covered by the filter element.
  • the air supply opening is arranged at a distance from the at least one filter element.
  • the air supply opening is arranged in an outer wall of the housing.
  • the advantage of this embodiment is that the air supply opening establishes a connection between the area surrounding the extractor hood, ie the room in which the extractor hood is operated, and the flow duct. As a result, ambient air can be sucked in and enter the flow channel through the air supply opening.
  • One advantage of this embodiment is that the routing of the exhaust air duct can be chosen freely, since it does not have to be in contact with the flow duct.
  • the exhaust air duct can extend vertically upwards and be screened by a chimney, for example.
  • the outer wall in which the at least one air supply opening is introduced can be one or more of the side walls of the housing and/or the top of the housing.
  • the air supply opening is arranged in such a way that it extends through the outer wall extends and ends inside the housing in the flow channel.
  • the air supply opening can be aligned horizontally, vertically or at an angle.
  • the flow channel is narrowed at the point of the air supply opening.
  • the advantage of this embodiment is that a negative pressure is set at the point of the air supply opening due to the narrowing of the flow channel. Ambient air or exhaust air is sucked in by this negative pressure and enters the flow channel.
  • This embodiment of the flow duct is used particularly advantageously in an extractor hood in which the air supply opening is made in an outer wall of the housing. Since the ambient air does not have a defined direction of flow, the negative pressure generated by the constriction or narrowing can generate an intake flow from the environment and thus ensure the reliable supply of air at the deflection point in the flow channel.
  • FIG 1 an area of an extractor hood according to the invention with a first embodiment of an air supply opening 16 in a flow channel 12 is shown. In the view shown, only the left half of the housing 1 of the extractor hood is shown.

  • an intermediate wall 14 is provided in the housing 1 inside the housing 1 and above the baffle plate 15 .
  • the intermediate wall 14 can be designed as part of the housing 1, ie it can be designed in one piece with the housing 1. However, it is also within the scope of the invention for the intermediate wall 14 to be a separate component which is fastened in the housing 1 .
  • the intermediate wall 14 lies parallel to the baffle plate 15.
  • a filter element 140 is accommodated below the fan 13 in the central area of the intermediate wall 14.

  • the partition 14 separates the exhaust air duct 11 from the flow duct 12.
  • the exhaust air duct 11 extends from the filter element 140 to the outlet opening 17 and the flow duct from the inlet opening 121 of the edge suction area to the filter element 140.
  • the fan 13 is arranged in the exhaust air duct 11 .
  • a negative pressure is generated in the flow channel 12
  • the Suction of contaminated air which is also referred to as fumes W
  • the baffle plate 15 prevents vapors from flowing directly against the filter element 140 in the extractor hood. Rather, the vapor W is conducted along the underside of the baffle plate 15 to the inlet opening 121 of the edge suction area of the flow channel 12 .
  • the vapor W that has entered is guided through the flow channel 12 to a filter element 140, through which it passes and is cleaned.
  • the exhaust air A is discharged to the outside through the outlet opening 17 due to the flow in the horizontal direction set by the blower 13 .
  • the flow channel 12 has a deflection point 120 at which the direction of flow of the vapor W is changed.
  • the deflection point 120 is a region of the flow channel 12 at which, due to the geometry of the flow channel 12 , the vapor W flowing in the flow channel 12 changes direction.
  • the geometry of the flow channel 12 is defined by the interaction of the housing 1 and, in the embodiment shown, the intermediate wall 14 with the baffle plate 15 .
  • an air supply opening 16 in the form of a bypass 160 is arranged at the deflection point 120 of the flow channel 12 .
  • the bypass 160 is designed as a recess in the intermediate wall 14 .
  • the bypass 160 thus establishes a connection between the exhaust air duct 11 and the flow duct 12 .
  • Part of the exhaust air A can enter the flow channel 12 in a targeted manner through this bypass 16 .
  • the flow that is generated by the part of the exhaust air A in the flow channel 12 can capture passing particles in the vapor W and thus prevent or at least reduce particles being deposited on the intermediate wall 14 .
  • figure 2 shows an area of an extractor hood according to the invention with a second embodiment of an air supply opening.
  • the bypass is designed as an air scoop 1600.
  • the air scoop 1600 is machined from the material of the intermediate wall 14 .
  • an opening is cut in the baffle 14 such that a portion of the material in the opening can be bent upwards.

  • FIG 3 an area of an extractor hood according to the invention is shown with a third embodiment of an air supply opening.
  • figure 3 shows the same components as in general figure 1 and therefore will not be explained again.
  • the air supply opening 16 is not arranged in the intermediate wall 14 but in an outer wall of the housing 1 of the extractor hood.
  • ambient air U can enter the flow channel 12 .
  • the flow channel 12 is narrowed at the location of the air supply opening 16 in the view shown.
  • this embodiment represents a passive variant. Due to the narrowing of the flow channel 12 in the embodiment shown, a negative pressure is established, which draws in the ambient air U. As a result, the ambient air U enters the flow channel 12 and can capture particles in the vapor W, as a result of which these are not deposited on the intermediate wall 14 or the housing 1 or are deposited to a lesser extent.
  • figure 4 shows a flow channel 12 of an extractor hood according to the prior art.
  • This representation shows that the flow duct 12 is delimited by a housing 1 and a baffle plate 15 in extractor hoods in the prior art. Furthermore, the figure 4 that the vapor W enters through the inlet opening 121 of the edge suction area of the flow channel 12 . The vapor W is deflected in the flow channel 12, whereby the direction of flow of the vapor W is changed.
  • a deflection of the vapor W by 90° is implemented in the suction gap constructions according to the prior art. Due to the high speed and the deflection of the fumes, particles P are deposited on the extractor hood itself, for example on housing 1. The disadvantage is that this increases the grease label of the extractor hood and shortens the cleaning intervals, and on the other hand that the deposits often are visible to the customer and therefore the hoods also lose their aesthetic appeal.
