Definitions

  • Filter device for an extractor device and extractor device with filter device
  • the present invention relates to a filter device for an extractor device and an extractor device with such a filter device.
  • Cooking processes usually produce steam and vapors.
  • combination devices are known, for example, in which an extractor device is arranged below the hob.
  • As a grease filter filter cassettes can be used in sol chen extractor devices, which consist, for example, of expanded metal layers that are firmly held in a frame.
  • sol chen extractor devices which consist, for example, of expanded metal layers that are firmly held in a frame.
  • the disadvantage of such types of filter is that the fat or other liquids that are deposited on the fat filter can run down the filter and drip off over the frame. In this way, components of the extractor device located below the grease filter are contaminated. Since these components are located below the suction opening of the extractor device inside the extractor device, they are difficult to access for the user.
  • the object of the present invention is therefore to create a filter device for a Dunstab extraction device in which air is sucked down through a suction opening, which on the one hand can ensure a reliable separation of impurities from the sucked in air and on the other hand cleans the Extractor device simplified.
  • the object is achieved by a filter device for an extractor device with a suction opening, through which air is sucked off downwards.
  • the filter device is characterized in that the filter device has a grease filter and a collecting container for collecting liquid with an opening for receiving at least a part of an edge of the grease filter and the width of the interior of the collecting container is greater than the thickness of the grease filter in the area in which this lies in the interior of the collecting container.
  • Directional information refer to the filter device and its components in an installed state, in which the filter device is built into an extractor device, in particular an extractor device of a combination device comprising a hob and extractor device, in which the air is sucked in downwards through a suction opening.
  • the front side is the side facing the user.
  • the back is the side that usually faces a mounting wall.
  • the rear side of the combination device is preferably the side via which purified air is output from the combination device.
  • the dimension in the direction between the front and back of the combination device is called the depth.
  • the horizontal dimension perpendicular to this is referred to as the width.
  • the vertical dimension is called the height.
  • a device As an extractor device, a device is referred to by means of which air, in particular special polluted air, for example in the form of fumes and vapors, can be sucked down from the space above a hob.
  • air in particular special polluted air, for example in the form of fumes and vapors, can be sucked down from the space above a hob.
  • the air is cleaned via the filter device and released from the extractor device as purified air or clean air.
  • the extractor device comprises a fan for this purpose.
  • the grease filter is preferably a flat filter which, for example, can have stretched metal layers or a knitted metal fabric as the filter material.
  • the grease filter can have a frame in which the filter material is firmly held, in particular clamped at the edges.
  • the filter device has a collecting container.
  • a collecting container is understood to be a container that is open to one side that is the top of the collecting container when installed.
  • the container is preferably elongated in shape.
  • the container is used to collect liquids that are deposited on the grease filter, in particular on the filter material, and which run under in or on the grease filter.
  • the opening of the collecting container is used to collect this liquid speed. In addition, the opening is used to accommodate at least part of an edge of the grease filter.
  • the edge of the grease filter protrudes through the opening into the interior of the collecting container.
  • the edge of the grease filter particularly preferably rests on the bottom of the collecting container.
  • the width of the interior of the collecting container is greater than the thickness of the grease filter in the area in which it is located in the interior of the collecting container.
  • the thickness of the grease filter is understood to be its dimension perpendicular to the surface of the grease filter. If the grease filter consists of several filter elements, the thickness of the grease filter is understood to be the sum of the dimensions of the filter elements and any distances between the filter elements.
  • the width of the interior of the collecting container is the dimension of the interior in the direction perpendicular to the longitudinal direction of the collecting container in the horizontal.
  • the edge of the grease filter that is received in the collecting container is preferably the lower edge of the grease filter.
  • the filter material is trapped at the edge.
  • a larger width of the collecting container enables a larger width of the opening of the collecting container. In this way, not only liquid can be collected from the collecting container that exits from the lower edge of the grease filter, but also liquid which drips off at a distance from the lower edge of the grease filter in the case of an inclined grease filter.
  • At least one grease filter is inclined in the filter device.
  • the filter surface of the grease filter can be enlarged at a small height and a targeted drainage of liquids along the grease filter can be ensured in comparison to a horizontally aligned grease filter.
  • the grease filter has a V-shape and the collecting container surrounds the grease filter at the tip of the V-shape.
  • the open side of the V-shape is directed upwards.
  • the grease filter can be made in one piece or in several pieces.
  • a filter element can be bent or folded in such a way that the V-shape is formed. Because the grease filter has a V-shape, the filter area can be maximized at a low height.
  • the angle of attack at which the air sucked in via a suction opening of a Dunstab.vor direction located above the filter device flows towards the grease filter is improved. In particular, a parallel The light flow that would occur with vertically aligned grease filters can be prevented. Because the collecting container is arranged at the top of the V-shape, it can collect liquid from both legs of the grease filter.
  • the grease filter is designed to be foldable. With a one-piece grease filter, this can be achieved through the choice of filter material. Alternatively, for example, in the case of a one-piece filter element, a weakening of the filter material can be introduced at the tip of the V-shape, which allows the filter element to be folded and in particular folded. Since the grease filter can be folded, it can be folded up, for example, for insertion and removal from a suction opening of an extractor device and only opened in the position below the suction opening.
  • the grease filter can also consist of two filter elements.
  • the individual filter elements can be pivotably attached to one another. This attachment can be direct or indirect.
  • the filter elements can be connected to one another via a joint or via the collecting container to which each of the filter elements is pivotably attached.
  • the grease filter therefore consists of at least two filter elements which are pivotably connected to the collecting container.
  • the grease filter is inextricably linked to the collecting container.
  • This embodiment has the advantage that the grease filter can be removed from an extractor device and cleaned together with the collecting container.
  • the grease filter is detachably attached to the collecting container.
  • the fastening is preferably such that it can only be released by a movement that differs from pulling the collecting container and the grease filter apart. Therefore, even with such a fastening, the grease filter with the collecting container can be removed together from an extractor device and, after removal, for example by pivoting the grease filter through a large angle, can be released from the receiving container.
  • the filter device has at least one deflector element which partially covers the opening of the collecting container.
  • An air guide element is referred to as a deflector element.
  • the deflector element is therefore preferably made of an air-impermeable material. Since the deflector element partially covers the opening of the collecting container, a calmed zone can be created below the deflector element in the collecting container. In this zone, liquid that has been separated out in the grease filter is prevented from being carried away by the air flow generated by the fan in the extractor device. In particular, in the lower area of the grease filter, in which a large amount of liquid accumulates, the discharge of this liquid by the air flow of the extractor device can be prevented.
  • At least one deflector element can represent a web which is directed from an upper edge of the collecting container into the opening of the collecting container.
  • the collecting container can represent an open rail and the web can be provided on the free end of at least one of the legs of the rail.
  • This deflector element in the form of a web creates, on the one hand, a calmed zone in the collecting container.
  • such a web and preferably two opposing webs at the opening prevents the liquid collected in the collecting container from being spilled when the filter device is removed from an extractor device.
  • At least one deflector element is offset from the collecting container to the open end of the collecting container and is offset inwardly towards at least one lateral edge of the opening of the collecting container.
  • the deflector Through passages for the grease filter are created between the deflector and the edge of the opening of the collecting container.
  • the calmed area is enlarged and thus the collection of liquids from a larger lower area of the grease filter in the collecting container is ensured.
  • the deflector element is an L-profile and is arranged in such a way that the free ends of the profile face the opening of the collecting container are. This results in a splitting of an air flow flowing in from above at the deflector element.
