Definitions

  • filter elements In the case of extractor hood devices that are used to clean polluted air, in particular kitchen fumes and vapors, it is known to use filter elements through which grease and other contaminants are filtered out.
  • the filter elements are therefore also referred to as grease filters.
  • filter cassettes in which a filter material is held in a filter frame are used as filter elements. These filter elements are inserted into the suction opening of the extractor device and, if necessary, attached via pin connections.
  • a handle can be provided on the filter elements in the surface of the filter material, by means of which the pins of the pin connection can be moved.
  • a disadvantage of these embodiments of the filter elements is that the user has to touch the filter element himself in order to remove it from the extractor device for cleaning, for example.
  • a first air filter is installed in the hood of a cooking area, for example.
  • a second filter is also installed in the hood.
  • the second filter includes a frame defining the front face through which incoming air can enter.
  • the outer perimeter of the front is defined by a top wall, a bottom wall and opposing end walls.
  • Two outer suction chambers and a central suction chamber are formed in the frame, which are separated from one another by partition elements which run along the front side.
  • a pair of handles are provided at the forward end of the end walls.
  • the walls of the suction chambers are each formed by an inner grid, an outer grid and filter material arranged in between. In addition, walls that extend between the end walls at the point of contact between two grids are provided.
  • an insert for a downdraft fan which comprises a removable filter element for filtering a flow of cooking vapor and a removable collecting element for receiving liquids, the collecting element has at least one wall which serves as a flow guide surface for deflecting the cooking vapor flow.
  • JP S44 17592 Y1 a filter device is shown which has a frame to which filter elements can be attached.
  • the WO 2014/191225 A2 describes a filter unit comprising a housing.
  • a removable module is placed in the housing.
  • UV lamps are installed in the removable module and handles are provided on the front.
  • the filter elements are arranged on the bottom of the housing separate from the module. The filter elements can only be removed when the module has been removed from the filter unit. In this filter unit, too, it is difficult to remove and clean the filter elements.
  • the US2012 / 204855A1 shows a combination device wherein the extractor device has a handle. This document discloses all the features of the preamble of claim 1.
  • the invention is therefore based on the object of creating a combination device with a filter unit, by means of which on the one hand the air can be cleaned reliably and on the other hand is easy to handle.
  • a structural unit is referred to as a filter unit for an extractor device, which can be inserted on or in a suction opening of the extractor device and by means of which the air can be freed from impurities.
  • the filter unit has at least one filter element.
  • the filter element can have filter material that is held in a filter frame.
  • the filter element consists exclusively of filter material.
  • the filter material can be, for example, expanded metal layers, a fleece, a knitted fabric or a knitted fabric.
  • the filter material can consist of wire.
  • the filter unit according to the invention has a filter holder.
  • the filter holder serves, on the one hand, to hold the filter element or elements on the extractor device and, on the other hand, to hold the filter element or elements on the filter unit when it is removed from the extractor device.
  • the filter holder has a base plate and at least one holding frame.
  • the base plate has at least one handle.
  • the handle can be molded into the base plate and / or comprise a separate handle element which is connected to the base plate.
  • the holding frame represents a receiving frame in which at least one filter element is held.
  • the holding frame surrounds at least part of the edge of the filter element.
  • the support frame is rigidly connected to the base plate. At least part of the holding frame can be designed in one piece with the base plate, for example.
  • the support frame is arranged inclined to the base plate.
  • the holding frame extends upwards or downwards from the base plate and forms an angle of, for example, 90 ° to less than 180 between the side from which the holding frame extends, i.e. the top or bottom of the base plate, and the holding frame °, for example 135 °.
  • a number of advantages can be achieved by arranging the holding frame at an incline in relation to the base plate according to the invention.
  • the handle since the handle is provided on the base plate and this is inclined towards the holding frame, the user can grip the handle without coming into contact with the filter element held in the holding frame.
  • the filter holder has at least two holding frames.
  • This configuration of the filter holder makes it possible to remove several filter elements, which are held in the holding frames, from the extractor device and to insert them into the same. It may be necessary to remove the filter unit from the extractor device for cleaning or maintenance purposes, for example.
  • the filter unit can be removed as a component and cleaned, for example, in a dishwasher.
  • the holding frames are firmly, that is to say rigidly, connected to the base plate, simple introduction of the filter unit into the extractor device can be ensured.
  • the relative position of the filter elements to one another is predetermined by the holding frames in which they are held.
  • the handle is arranged on the side of the base plate which faces away from the direction of extent of the at least one holding frame. This means that the handle is located on the side of the base plate that faces away from the side over which the at least one holding frame extends.
  • the handle is provided on the top of the base plate and the holding frames extend downward from the base plate.
  • the handle Since the handle is turned away from the holding frames, on the one hand, accidental contact with the filter elements when gripping the handle can be prevented.
  • the filter unit can be easily introduced into and removed from an extractor device, for example in a suction opening with an extractor device located below the suction opening.
  • the handle can remain largely free of grease, since it is not located in the inflow area of the filter unit.
  • the inflow area which can also be referred to as the vapor area, is rather formed by the holding frames with the filter elements held therein. If several holding frames are provided, each with at least one filter element, then each of the holding frames forms a suction area of the filter unit.
  • the at least two holding frames are particularly preferably inclined in the same direction to the base plate.
  • the holding frames can both be inclined downward from the base plate.
  • the angle enclosed by the two holding frames with the side of the base plate from which the holding frames extend is preferably also the same.
  • both holding frames can be inclined at an angle of, for example, 100 ° to the underside of the base plate and thus protrude laterally beyond the side edges of the base plate on which they are provided.
  • holding frames are provided, these are preferably arranged on opposite edges of the base plate.
  • the holding frame consists of at least two components that are detachably or non-detachably connected to one another.
  • the components are also referred to as frame parts and each have an opening which preferably forms the largest part of the frame part. This allows air to flow through the frame parts. Due to the multi-part construction of the holding frame, one or more filter elements can be introduced between these components, that is to say frame parts, and held between them during the production of the filter unit. This simplifies production.
  • the connection between the frame parts can be achieved, for example, by gluing, welding or locking.
  • a first of the frame parts of the holding frame is designed in one piece with the base plate and a second of the frame parts is connected to the first frame parts.
  • This configuration further simplifies production, since only the filter element or elements and the second frame part have to be aligned during production. Due to the one-piece design of the first frame part with the base plate, the frame part is firmly connected to the base plate. The position of the frame part firmly connected to the base plate, however, is fixed. The filter element or elements can thus be placed on or inserted into the stationary frame part. The second frame part can then be applied to the other side of the filter element and this can then be connected to the first frame part.
  • the frame parts preferably have a fold at their edges, through which the frame parts each form a receiving space.
  • the frame parts preferably have a fold at their edges, through which the frame parts each form a receiving space.
  • the further frame part is designed flat, that is to say consists only of the strip of material that forms the frame.
  • the holding frame consists of two frame parts which are fastened to one another at at least a part of their edges. Because the support frame consists of frame parts, the air permeability of the filter material is only slightly impaired. Since the frame parts are also fastened to one another at their edges, it is not necessary to provide connecting elements in the area of the openings of the frame parts, which could hinder a flow. In addition, by fastening the frame parts to one another, it is possible to hold filter material in the holding frame, which consists of several layers and / or has no dimensional stability. With such filter materials, the edge formed by the connection of the frame parts at their edges can serve as an edge holder for the filter material and hold it reliably.
  • the filter material is here preferably clamped between the material strips of the frame parts that surround the opening.
  • one of the frame parts of the holding frame represents an inner frame and a frame part represents an outer frame.
  • the outer frame or the inner frame can be rigidly connected to the base plate and, in particular, be designed in one piece with it. If the outer frame is rigidly connected to the base plate, the filter element or elements are placed from the inside into the outer frame and then pressed against the outer frame from the inside by applying the inner frame and held between them after the inner frame has been attached to the outer frame. If, on the other hand, the inner frame is rigidly connected to the base plate, then the filter element or elements can be placed in the outer frame from the outside. The outer frame is then attached to the filter elements from the outside and connected to the inner frame.
  • the frame part is referred to here as the outer frame, which, when the filter unit is installed in the extractor device, lies on the inflow side of the filter elements.
  • the outer frame therefore represents the inflow side of the filter unit through which the air to be cleaned enters the filter element or elements.
  • the frame part that rests on the clean air side, i.e. the outflow side of the filter element, is referred to as the inner frame.
  • the inner frame thus represents the outflow or clean air side of the filter unit, through which the cleaned air exits the filter element.
  • the outer frame is preferably rigidly connected to the base plate and is particularly preferably designed in one piece with the base plate. This has the advantage that the number of joints or other connection points on the inflow side of the filter unit is small and thus the accumulation of impurities on the filter holder can be minimized.
  • the inner frame preferably has at least one support strut and the outer frame has at least one holding strut.
  • the support strut and retaining strut can be designed in the same way and are referred to differently only for better understanding.
  • the struts extend through the opening of the respective frame part, that is to say span them the opening. This embodiment improves the hold of the filter element in the holding frame.
  • the filter element consists of filter material.
  • no separate filter frame is provided on the filter element.
  • the filter holder of the filter unit according to the invention since a holding frame can take over the function of the filter frame.
  • the holding frame holds several layers of filter material together or supports and holds a dimensionally unstable filter material, for example a wire mesh or wire mesh, securely between the frame parts.
  • the at least one holding frame is preferably arranged on an edge of the base plate, that is to say extends from the edge of the base plate. It is also within the scope of the invention to provide the holding frames in the surface of the base plate, for example on the underside of the base plate at a distance from the edge of the base plate.
  • the manufacture of such a filter holder is more difficult due to the geometry.
