Definitions
- the present invention relates to an extractor hood.
- the extractor hoods for example, over a stove, extracted air is loaded with impurities such as water, grease, oil and the like.
- the object of the present invention is therefore to provide an extractor hood in which the deposition of particles on the extractor hood is reduced.
- the invention is based on the finding that this object can be achieved by providing at least one air supply opening on the extractor hood, through which air enters the flow channel and influences the vapor stream in the extractor hood.
- the object is therefore achieved by an extractor hood comprising a fan, at least one filter element, a baffle plate and a housing, which forms at least part of a flow space, which comprises a flow channel with a Randabsaugungs Scheme having at least one inlet opening.
- the extractor hood is characterized in that at least one air supply opening is arranged in the region of at least one deflection point of the flow channel.
- a fume extraction device is referred to, which is used in the home, especially in a kitchen for removing and cleaning cooking fumes, which are also referred to as vapors.
- the extractor hood represents, for example, a ceiling-mounted or a wall-mounted extractor hood.
- the extractor hood has a housing which can also be referred to as a viewing hood. In the bottom of the housing, a suction port is introduced.
- the housing forms at least part of a flow space.
- the fan of the hood which is also referred to as a fan, arranged in the flow space.
- a negative pressure is generated, which serves for the suction of contaminated air, from around and in particular from below the extractor hood.
- Contaminated air also referred to as vapor, may enter the cooker hood via the suction port located in the bottom 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 preferably represents a filter element for filtering out particles, in particular of grease, oil or water particles.
- the filter element preferably represents a planar element whose one surface at least partially serves for the admission of contaminated air into the filter material.
- a filter material according to the invention for example, expanded metal can be used.
- the filter element is received in a frame.
- the frame can additionally serve for fastening 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 cartridge and is also referred to as a grease filter.
- the extractor hood includes a baffle plate.
- the baffle plate is an air-impermeable component, which is preferably a disc or plate.
- the baffle plate is arranged in or below the suction opening of the housing of the extractor hood.
- the baffle plate also serves as a deflecting element, which prevents the uncontrolled and direct, that is to say immediate, influx of the at least one filter element through wafers flowing from below to the extractor hood.
- the baffle plate therefore preferably covers an area which is larger than the area of the filter element or, in the case of several filter elements, the filter elements.
- the baffle plate preferably has a size which is smaller than the size of the suction opening of the housing. Between the bottom of the housing and the edge of the baffle plate thus a gap is formed, which is also referred to as Randabsaugspalt or Randabsaug Symposium.
- the housing forms at least part of a flow space.
- the flow space comprises a flow channel.
- the region of the extractor hood is referred to as a flow channel which lies between the edge suction region and the at least one filter element provided in the housing.
- the flow channel is limited by the housing and the baffle plate.
- the housing limits the flow channel to the sides and upwards and the baffle plate limits the flow channel downwards.
- the housing at least partially forms the flow channel of the flow space of the extractor hood.
- the vapor is directed within the extractor hood and in particular within the housing to the at least one filter element.
- the flow channel comprises an edge suction area.
- the edge evacuation area is defined by the gap between the housing and the baffle plate.
- the Randabsaugungs Scheme web or other connecting means may be provided.
- the entire Randabsaug Scheme forms the inlet opening and thus can enter the inside of the hood over the entire Randabsaug Colour vapor. Since the Randabsaug Scheme forms part of the flow channel, the vapor can thus enter the flow channel.
- the flow channel extends from the inlet opening of the Randabsaugungs Schemees to the at least one filter element.
- At least one deflection point is formed in the flow channel.
- a deflection point a point in the flow channel is referred to, at which the flow direction of the vapor is changed in the flow channel.
- 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.
- Particularly preferred as a deflection point is the point at which occurs due to the geometry of the flow channel, the first change in direction of the Wrasens within the flow channel. Further changes in direction in the flow channel can be done for example by the negative pressure generated by the blower. However, these changes in direction are not caused by the geometry of the flow channel and thus do not constitute a deflection point in the sense of the invention.
- an air supply opening is provided in the region of at least one deflection point.
- the air supply opening is provided on the flow channel in the region which lies at the deflection point or in the flow direction after the deflection point.
- a corner or a curvature of the housing may be present, by which the direction change of the Wrasenstroms is effected.
- the air supply opening is a recess in the sense of the present invention.
- the air supply opening is a hole or a slot. The shape of the hole or slot can be chosen freely.
- more than one air supply opening may be provided in the region of the deflection point of the flow channel.
- the air which enters the flow channel through the air supply opening may be exhaust air or ambient air.
- the flow of fumes is advantageously influenced by the entry of air into the flow channel.
- the vapor is deflected more effectively than in the devices which are known in the art, and thus directed to the filter element.
- the air entering through the air supply opening captures particles passing from the vapor and thus also prevents deposition of the particles in the flow channel and in particular on the housing of the extractor hood. This overall improves the fat label of the cooker hood.
- the deposition of visible grease in the intake area is avoided, thus increasing customer satisfaction. It is also advantageous that the formation of Fettan- collections is avoided in an area from which the fat could drip down through the inlet opening of the hood down to the stove.
- the air supply opening is arranged at a distance from the inlet opening of the edge suction area.
- Spaced in the sense of the present invention means that the air supply opening and the inlet opening are not arranged in the immediate vicinity of each other and therefore have no points of contact.
- An advantage of this embodiment is that this causes the vapor to enter the flow channel only via the inlet opening before it is influenced by the air entering the flow channel through the air supply opening.
- the distance that the vapor, which has passed through the inlet opening of the Randabsaugrios, up to the deflection point in the flow channel travels back into account. Accordingly, it is ensured that the vapor is influenced only in the region of the deflection point by the occurred air and not already for example when entering the vapor in the flow channel.
- the exhaust duct may be a pipe or a duct which is perpendicular or parallel to the flow duct.
- the region of the extractor hood is referred to as an exhaust air duct, which adjoins the filter element in the flow direction.
- the blower of the extractor hood is arranged in the exhaust duct.
- the Exhaust duct has an outlet opening through which the exhaust air can be discharged to the outside.
- the exhaust air in the room in which the cooker hood is operated, or outside the building in which the hood is operated are delivered.
- the exhaust duct can be at least partially formed by the housing of the hood.
- the exhaust air duct can also be formed by a separate component, for example a pipe, which can be clad in a forge, for example, by a chimney.
- the air supply opening is a bypass between the exhaust air duct and the flow channel.
- the bypass connects the exhaust air duct fluidly with the flow channel.
- a part of the exhaust air from the exhaust air duct can be passed into the flow channel via the bypass. Since the bypass forms the air supply opening, the exhaust air is introduced in the region of the deflection in the flow channel.
- An advantage of using the exhaust air as supply air, which is introduced to prevent deposits in the flow channel, is that the flow of exhaust air is forced through the blower and this flow can therefore be used in a simple manner for supplying the exhaust air into the flow channel ,
- the bypass can be realized by a separate component, such as a pipe.
- the exhaust air duct is arranged above the flow channel and adjacent thereto.
- the flow channel and the exhaust air channel run parallel at least in some areas and have at least one contact point.
- at least a part of the flow channel lies in the horizontal and the exhaust air duct is located on the horizontal part of the flow channel.
- the exhaust duct in this embodiment therefore extends horizontally and the outlet opening of the extractor hood is preferably provided on the side of the extractor hood.
- the advantage of this embodiment is that in this case a bypass between the exhaust air duct and the flow channel can be produced in a simple manner. By the two channels are adjacent to each other, the distance that must be overcome for the supply of a portion of the exhaust air to the vapor in the flow channel, low.
- the exhaust duct and the flow channel are separated by an intermediate wall.
- the intermediate wall is a planar component and preferably represents a plate or a sheet metal.
- the intermediate wall can, according to the present invention, consist of a sheet metal material, in particular of stainless steel sheet.
- the advantages of the present invention can be used particularly easily.
- the distance between the exhaust air duct and the flow channel is given in this embodiment only by the intermediate wall.
- the intermediate wall separates the flow space into two regions, namely into the exhaust air duct and into the flow duct.
- the intermediate wall forms the top of the flow channel and the bottom of the exhaust duct.
- the exhaust duct is limited in this embodiment up through the top of the housing.
- the intermediate wall may be part of the housing or be incorporated as a separate component in the housing.
- the air supply opening is arranged in the intermediate wall.
- the air supply opening serves as a bypass between the exhaust duct and the flow channel.
- 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 introduced, for example, by punching or lasing in the material of the intermediate wall.
- Outgoing air duct are discharged from the fan in a horizontal direction to the outside and the flow of the vapor in the flow channel can be directed in the horizontal direction to the filter element.
- the part of the exhaust air which enters the flow channel via the air supply opening thus preferably enters the flow channel in the vertical direction through the air supply opening. It is also advantageous that a part of the exhaust air can be selectively reintroduced into the flow channel through the connection between the exhaust air duct and flow channel by means of an air supply opening in an intermediate wall and thus can influence the vapor. Due to the pressure differences between the exhaust air duct and the flow channel, the entry of part of the exhaust air into the flow channel is favored. This part of the exhaust air, which serves as supply air, generates a flow, which passes in the Wrasen
- the air supply opening is designed as an air scoop.
- the air scoop is an air supply opening, at the inlet side of which an air guide element is arranged. Air from a flow along the scoop is directed to the air supply opening via the air guiding element.
- the air supply opening is an air scoop, thus the supply of air to the flow channel in the region of the deflection favored and thus reduces the deposition of particles or completely prevented.
- the air scoop may be provided on an outer wall of the housing and may pass a portion of the ambient air into the flow channel.
- the air scoop is formed between the exhaust air duct and the flow channel and is machined out of the material of the intermediate wall.
- the working out of the scoop from the material of the intermediate wall takes place, for example, that in the material of the intermediate wall, which is usually sheet, an opening or a slot is cut, lasered or stamped and then the material in the region of the opening or of the slot is bent upwards. Since the exhaust air duct is preferably above the flow channel and in particular above the intermediate wall, the upwardly bent material protrudes into the exhaust air duct.
- the upwardly bent portions of the machined material of the intermediate wall form protrusions, which may have a tab-like shape.
- the tab is aligned so that it against the flow direction of the exhaust air in the exhaust duct is directed and thus a part of the exhaust air is detected by the scoop and directed into the air supply opening.
- An advantage of this embodiment is that the air scoop can be made in a simple manner and a reliable supply of exhaust air in the flow channel allows light.
- 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 is referred to, which is surrounded by the intermediate wall.
- the outer edge of the intermediate wall is in a perpendicular projection on the filter element 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 a vertical projection.
- the intermediate wall extends laterally beyond the edges of the filter element, forwards and backwards. The intermediate wall thus forms a flat frame around the flat filter element.
- the filter element below the intermediate wall or on the intermediate wall.
- the intermediate wall has a passage opening, which is covered by the filter element.
- the air supply opening is arranged at a distance from the at least one filter element.
- An advantage of this embodiment is that the flow, which is generated by the entry of air through the air supply opening in the flow channel, can influence the vapor before it passes through one of the filter elements and is cleaned. As a result, it can be ensured that during the deflection of the vapor flow in the flow channel, a separation of particles from the intermediate wall or the housing can be reduced or avoided.
- the air supply opening is arranged in an outer wall of the housing. An advantage of this embodiment is that the air supply opening establishes a connection between the environment of the extractor hood, that is the space in which the extractor hood is operated, and the flow channel.
- the exhaust duct may extend vertically upwards and be blinded for example by a chimney.
- the outer wall, in which the at least one air supply opening is introduced may be one or more of the side walls of the housing and / or the top of the housing.
- the air supply opening is arranged so that it extends through the outer wall and ends in the interior of the housing in the flow channel.
- the air supply opening may be oriented horizontally, vertically or inclined.
- the flow channel is narrowed at the location of the air supply opening.
- a negative pressure is set by the narrowing of the flow channel at the location of the air supply opening. This negative pressure draws in ambient air or exhaust air and enters the flow channel.
- This embodiment of the flow channel is particularly advantageously used in an extractor hood, in which the air supply opening is introduced in an outer wall of the housing. Since the ambient air has no defined flow direction, an intake flow from the environment can be generated by the negative pressure generated by the constriction or taper and thus the reliable supply of air at the deflection point in the flow channel can be ensured.
