Definitions

  • the present invention relates to a filter system, in particular for an extractor hood device, according to the type defined in more detail in the preamble of claim 1.
  • DE 39 29 440 C2 discloses a device designed as a module for preparing and consuming warm dishes with a table top, a heating surface arranged thereon and an extractor device.
  • the extractor device is arranged as a hood with shelves and communication devices spaced above the table surface. Furthermore, the extractor device is designed with cleanable filters, which are made of stainless steel, so that they can be cleaned in a simple manner.
  • a filter cassette for extractor hood devices in which a grease filter made of non-metallic material is arranged in the vapor flow path between two metal grease filters which are arranged at a distance from one another and which form the top sides of the filter cassette.
  • the metal grease filters are made of expanded metal and each of the two deck sides has at least one layer of expanded metal.
  • this filter cassette for extractor hood devices known from the prior art has the disadvantage that the grease filter has dimensions of very large filter areas such that it can no longer be positioned and washed in conventional dishwashers.
  • Extractor hood devices or flat screen hoods with a housing and an associated filter system are known from practice, the filter system of which is arranged in a suction area and has at least two filter devices arranged next to one another, which are detachably connected to the housing. Because of their split design, these filter devices also have dimensions, even with larger filter areas, which allow regeneration in conventional dishwashers.
  • extractor devices have the disadvantage that the suction surface of the extractor device facing the suction area has a fluidically unfavorable surface with dead spaces in the joint area of the filter devices due to the filter devices arranged next to one another, which undesirably leads to a deterioration in the filter performance of the extractor device.
  • the present invention is therefore based on the object of providing a filter system whose filter devices can be regenerated or washed in conventional dishwashing devices and which is designed with a suction-side surface which does not impair the filter performance.
  • the filter system according to the invention is preferably designed on its suction side with a holding device for holding the filter devices which extends over the suction surface of the filter system and through which the suction air to be filtered can flow and which has an at least approximately aerodynamically optimized surface on the suction side.
  • the configuration of the filter system according to the invention advantageously offers the possibility of executing the filter system even with larger filter areas with two or more individual filter devices, which can be regenerated or washed in each case in conventional dishwashers. Due to the holding device upstream of the filter devices in the flow direction of the intake air to be filtered, dead spaces which exist in the joint area between the individual filter devices are covered by the suction device-side surface of the holding device, which is essentially optimized in terms of flow technology, thereby improving the filter device.
  • the holding device is on its suction side with a Plate executed, which has several through openings.
  • a plate with through openings is on the one hand easy to manufacture and on the other hand has a smooth surface which is neither designed with dead spaces nor with other aerodynamically unfavorable contours.
  • the holding device comprises a frame which at least partially surrounds the plate and is detachably connected to a housing, preferably a housing of an extractor device or a housing of an auxiliary unit assigned to the extractor device.
  • the filter system thus represents an easy-to-use module, which can be removed from the housing as a modular component in one operation for cleaning the filter system or also for maintenance work on an intake device.
  • the plate can be detachably connected to the frame, which advantageously simplifies cleaning of the filter system, since portions of the plate and the frame in the region of joints between the frame and the plate, which are difficult in the assembled state of the plate in the frame are accessible, can be cleaned in a simple manner in the disassembled state of the holding device.
  • the holding device can be designed with at least one handle device for inserting the holding device into the housing or for removing the holding device from the housing.
  • the handling of the filter system during assembly or disassembly can be further simplified if the handle device is designed with at least one spring-loaded engagement element which can be countersunk in the frame for disassembling the holding device. It is thereby advantageously achieved that the filter system is a module with a small number of components and can be installed in the housing of the extractor device or can be removed from it without additional tools.
  • the filter devices are designed with a filter element and a frame part, the filter elements preferably being made of expanded metal.
  • the filter devices are each designed with at least one handle module for mounting the filter devices in the holding device or for removing the filter devices from the holding device, the assembly or disassembly of the filter system itself is advantageously simplified, with the handle modules of the filter modules being shown in a further advantageous embodiment
  • Filter devices can be implemented with at least one spring-loaded handle element, which can be sunk in the frame parts of the filter devices in order to remove the filter devices.
  • a form fit is formed between the filter devices and the holding device in some areas, which automatically detaches the filter devices from the holding device, especially when removing the filter system from the housing. This advantageously reduces the risk of injury to an operator while handling the filter system in a simple manner.
  • the holding device can have a central web between the two filter devices, as a result of which the stability of the filter system is increased in a simple manner, which has a particularly advantageous effect in the case of extractor hood devices designed as flat screen hoods with a pull-out screen.

  • the filter system 1 is shown in FIG. 1 in a schematic three-dimensional bottom view, in which a holding device 2 is shown with a plate 3 with a plurality of through openings 4 and a frame 5 surrounding the plate 3.
  • the holding device 2 is designed in such a way that the plate 3 on the side of the filter system 1 facing the suction area of the extractor device extends over the entire suction surface of the extractor device and, due to the through openings 4, can be traversed with suction air to be filtered or cooking fumes sucked in.
  • the through openings 4 are designed in terms of flow technology in their inflow regions for sucked-in air in such a way that a flow of the sucked-in air can be conducted through the plate 3 without turbulence and with only a slight flow resistance.
