Description
Technical field
The present invention relates to a kind of filter for installation that is used for Wo 2008055837.
Background technology
At Wo 2008055837 middle filtrator device especially for from the smog that sucks by Wo 2008055837, isolating dirt, fat particles particularly.What usually use on the kitchen range top is that some and horizontal line tilt to extend, particularly conical grease filter device, and wherein steaming on the kitchen range face or the steam that boils consist predominantly of thin liquid and the grease non-resin shape, for example vegetable oil.The grease of separating from smog in these devices, perhaps collected liquid is discharged downwards by the support of adhesion, and is collected into there in the collection container.For example a kind of like this filter for installation has been described at DE 197 53687 A1 and DE 10 2,005 019 831 A1.
The shortcoming of this filter for installation is that the gradient of filtering surface is too little, and like this, the grease that is separated can not flow in the grease collection container reliably, and can drip on the kitchen range top.
Summary of the invention
Therefore task of the present invention provides a kind of filter for installation, use a kind of like this filter for installation can be reliably with the dirt of in filter material, separating, the dirt of fluid particularly, import in the collection container as oil, fat and water, and allow filter for installation to have little structure height in addition.
The present invention is to be foundation with this understanding, promptly except one first filtering surface that tilts another suction area is set also, contaminated air can be incorporated in this filter by this suction area.
This task is to finish by the filter for installation that is used for Wo 2008055837 according to the present invention, it has one first filter cell and one and is arranged on collection container below first filter element, wherein, the filtering surface of first filter element is a body that vertically extends, the lower limb of first filter element is a discharging area, and described filtering surface is one first suction area.This filter for installation is characterised in that this filter for installation has one second suction area, and the discharging area in first district is between first and second suction areas.
Situation about gradient, direction and relative position all relates to the installment state of filter for installation in Wo 2008055837.
Body is called the body that vertically extends, and its face is so directed, and promptly its direction has one greater than zero vertical component.Such zone of filter element is referred to as discharging area, and promptly the dirt that is held in filtering material by this zone, particularly fluid dirt can leave filter material targetedly as oil, fat and water.Particularly the such zone with filter element is referred to as discharging area, i.e. filter element and discharger acting in conjunction in this zone.Discharger for example can be a guide groove or a thin plate.In any case but discharger can not be designed for the air that filtration is made dirty, not filtering material especially, as metal lath.Acting in conjunction between filter element and the discharger can be that filter element places or leans against on the discharger.Instead this acting in conjunction can be positioned at above the discharger by discharge area, and those dirts that are generally fluid can drip in the discharger by this measure.Particularly preferably the discharging area of filter element is the edge of filtering surface.This edge forms the minimum position of filter element when installment state.
Collection container is so be arranged on first filter element following, and promptly foul can directly arrive the collection container from filtering surface, particularly splashes in this collection container.Collection container is as discharger in this case.An independent discharger instead can be set.Can arrive in the collection container by this device foul.
Filtering surface can be made of metal lath, hole graticule mesh, fleece or other filtering materials.
The filtering surface of first filter element is one first suction area.Such zone of filter for installation is referred to as suction area, promptly air can be sucked by a fan that in Wo 2008055837, is provided with by this zone, and this air enters into filter for installation from the outside, and preferably is directed to by a filter there.The meaning from the outside is meant these air that arrive suction area filter element of guiding process filter for installation before in this respect.Thisly also be referred to as smog below by dirty air usually.
Filter for installation has one second suction area according to the present invention, and the discharging area in first district is between first and second suction areas.Because the discharging area of first filter element is arranged between first and second suction areas, so can guarantee on the one hand and will discharge that the dirt that perhaps drips can be discharged from from first filter element.Therefore needn't worry that foul penetrates in the filter element that preferably is provided with in the zone of second suction area.In addition, be divided into the geometric parameter that one first suction area and one second suction area can be selected single suction area according to external circumstances by suction zone with filter for installation.This point is impossible in only having traditional filter for installation of a suction area, because be that the size of suction area is by the decision of desirable suction power and desirable cleaning effect at least.
Because discharging area is arranged between the suction area, so just can guarantee to discharge reliably dirt, this may be not all right in having only a big filter for installation with the setting of discharging area suction area.
Be arranged in the zone of second suction area according to one second filter element of a preferred form of implementation.The zone that is provided with filter element of suction area can be close to the porch setting that smog enters into filter for installation according to the present invention.Also can be with filter element with respect to inlet hole, the inside inside that is set to filter for installation of inlet hole just wrongly.By filter element is arranged in the zone of second suction area, and when selecting greatlyyer, the area of inlet hole can prevent also that dirty air or smog from penetrating in the Wo 2008055837.
Though mainly relate to one second or inner filtration parts below, also can be provided with a plurality of second or the inner filtration parts according to the present invention.
Particularly in such form of implementation, promptly one second filter element is arranged in the zone of second suction area therein, can increase the size of whole filtering surface, and perhaps the size of a regulation can preferably be divided into first and second filter elements.Particularly the form owing to first filter element makes these schemes significant.Because this filter element is vertically to extend, so at the filtering surface of traditional filter for installation, and therefore the size of suction area is only by enlarging the height of filter element, enlarge width or diameter, perhaps finish by enlarging at the upside of filter element and the stand out between the downside or diameter difference.Usually filter is arranged on the downside of a Wo 2008055837 on a kitchen range top or the operating desk.The smog that will occur on the kitchen range top or operating desk reliably for the fan that uses Wo 2008055837 sucks, and must make between Wo 2008055837 and the kitchen range to keep small distance.Therefore the height possibility that increases filter element in order to increase filtering surface is limited.Width or diameter also can only enlarge in the scope by the width dimensions that Wo 2008055837 provided in a filter element, and strengthen filtering surface and be arranged on the kitchen range top below the Wo 2008055837 or alignment that workbench needs.The stand out or the diameter that can only change conditionally in the filter element is poor at last.The diameter of filter element on upside and the downside or the difference between the width too conference cause the gradient of filtering surface or gradient little.This little gradient can cause the undesirable thin fluid dirt of people, drips on the kitchen range top as oil, water and fat.
Use the present invention can so select the shape and size of the filtering surface of first filter element, promptly this filtering surface has the favourable height and the gradient, particularly has the little height and the big gradient.Although the described parameter of filter for installation is unfavorable to efficient and reliability usually, owing to be provided with the desirable efficient that second suction area with filter element also can get filter device and Wo 2008055837 in addition.
Preferably second filter element is according to the inside that is positioned to the projection of horizontal plane by the zone that discharging area limited of first filter element.
Horizontal plane or horizontal line in the mounted Wo 2008055837 of regulation according to the present invention can be regarded as horizontal plane.Horizontal plane is normally perpendicular to the wall of installing on the Wo 2008055837.It is parallel with lid to be installed in the Wo 2008055837 upper horizontal plane that covers at one.Because first filter element is vertically to extend, so this filtering surface with respect to the horizontal plane tilts.The meaning that tilts according to regulation of the present invention is to have one greater than zero angle with horizontal plane.Angle between the outside of horizontal plane and filtering surface is greater than 0 °.Preferably in the outside of horizontal plane and filtering surface folded low-angle greater than 45 °, particularly preferably greater than 60 °.Particularly preferably first filter element is a body that shrinks downwards, and like this, the minimum angles between the outside of horizontal plane and filtering surface is preferably less than 90 °.
Can guarantee that by second filter element being arranged in the zone that is limited by discharging area first and second filter elements are not overlapping at vertical direction, perhaps be not stacked.A kind of so overlapping meeting causes dirt to drop onto on first filter element from second filter element, and this can damage the inlet capacity and the carrying capacity of first filter element.
Second filter element preferably vertically is arranged in the vertical zone that top edge and lower limb limited by first filter element at least in part.Second filter element can be accommodated in first filter element thus.Preferably second filter element fully is accommodated in first filter element, in other words, is surrounded by this filter element.Structure height by this design filter for installation is only determined by first filter element and collection container.
According to a preferred form of implementation, second filter element has a discharging area, and the discharging area of this discharging area and first filter element adjoins.At this, such zone of filter element also is called the discharging area of second filter element, and promptly the dirt that is held in filter material by this zone can break away from filter material targetedly.Particularly such zone of filter element is called discharging area, i.e. filter element and discharger acting in conjunction in this zone.Preferably discharging area also is positioned at its lower limb for second filter element.Adjoining of the discharging area of the discharging area of second filter element and first filter element can be represented reclining of these zones, adjacent setting, the perhaps coincidence in these two zones.For example have the coincidence in these zones in such a case, that is, first and second filter elements are one-piece design, and form a common filter unit.Because the discharging area of these two filter elements adjoins each other, so can discharge the dirt that from these two filter elements, comes out by a unique discharger.Simplified the structure of filter for installation by this measure.
According to the present invention, collection container can so be arranged on first filter element below, can prevent to drip on the kitchen range top.The size of collection container makes this collection container block the zone that the discharging area by first filter element limits at least in this case.Do not need independent discharger in this case.But preferably filter for installation comprises the discharger that extends to collection container from the discharging area extension of first filter element.Can reliably the dirt that comes out from first filter element be incorporated into the collection container by an independent discharger is set, and can stop dirt to drop onto to be positioned on the kitchen range top below the filter for installation.There is not the form of implementation of independent discharger to compare the size that yet can reduce collection container in this form of implementation neutralization, particularly its width or diameter.Last this discharger can be additionally as the fixture that collection container is fixed on first filter element.On discharger, fastener can be set, for example screw hole or stop device for this reason.
Collection container preferably has spacing ground to be provided with the discharging area of first filter element.Can between the discharging area of the top edge of amount discharge container and filter element, form a suction area by this spacing.Can enter into the inside of filter for installation by this suction area air, and can be introduced in second filter element that is provided with where necessary.
If a discharger is set on the discharging area of first filter element, then this discharger preferably has at least one inlet hole.Can keep second suction area of filter for installation by described inlet hole, although also can be used for entering of smog because be provided with the gap of discharger between discharging area and collection container.In addition, these inlet holes in the discharger that a basic horizontal is extended can be used for arriving collection container from the dirt that drips second filter element of the inside of first filter element setting.These dirts pass these inlet holes.Yet following way also is fine, and promptly discharger only extends to the top edge of discharger from the discharging area of filter element.These inlet holes are set up in this case, thereby enough materials of discharger also are set between them, so that dirt is directed to collection container from discharging area.
Particularly preferably discharger is designed to the plate of arch.Lean against on the discharging area of first filter element at this plate on the edge, and to the third side of plate to depression.Collection container can be in the minimum zone of center fixation at this plate.Between the fixture of collection container and edge, some inlet holes are set in plate.Brace extends from the edge to minimum zone between these holes.These braces are to be used to keep collection container on the one hand, and are to be used to guide those not arrive the lowermost extent of the dirt course plate of collection container by inlet hole on the other hand.Some drippage holes can be set there.Can arrive collection container by these these dirts of drippage hole.
These inlet holes in discharger preferably large scale design, and cover the major part on the surface of discharger.Can guarantee that by this measure the air that enters second suction area can not be obstructed, and particularly not hinder dirt and enter collection container for the discharger that is designed to plate.
According to a preferred form of implementation, first and second filter elements constitute by the body that dwindles respectively, and second filter element and first filter element are reverse.First filter element is preferably so directed, and promptly this filter element down dwindles, and second filter element up is provided with a side of dwindling.Can utilize best by the second such filter element and to be positioned at the first filter part volume inside.Filtering surface with a kind of like this filter part is compared much bigger with a flat filter.Second filter element can be its contraction one side closed.This side can form by a lid.This lid also is to be made of filtering material.Also can use a kind of air-locked lid, perhaps design a kind of second filter element of uncovered.
First and second filter elements for example can have a kind of truncated cone shape, perhaps have a kind of truncated pyramid shape.
Be designed to single-piece according to form of implementation first filter element and second filter element, that is to say to form an integral body.These two filter elements can be fixed to one another to form a filter unit.Finish on the preferably this discharging area that is fixed on two filter elements.Instead this filter unit also can be made by a kind of unique raw material or semi-finished product, and so forms the unit of an integral body.If this filtering material for example is metal lath or gauze, then these two filter elements can be made by crooked semi-finished product.
