Description

The present invention relates to a filter device for an extractor hood and an extractor hood.

In extractor hoods, it is known to use filter elements through which impurities in the air, in particular fat, can be separated from fumes and vapors and the air can thus be cleaned. The filter elements must be freed at regular intervals from the deposited impurities. For this purpose it is necessary to remove the filter elements from the extractor hood. Nowadays filter elements are therefore designed so that they have, for example, retractable pins on an edge of the filter element, which can be retracted by means of a handle. Fixed tabs are generally provided on the opposite edge. After retracting the retractable pins, the filter element can in this case be pivoted downwards from the suction opening of the extractor hood. Then the filter elements must be solved by levering the tabs out of the openings in which they are held by the hood. In order to prevent the filter element from falling down, a safety device must be provided in this type of filter attachment. Such a filter element with safety device is for example in the DE 101 62 921 A1 described.

A disadvantage of this type of filter attachment lies in the complex removal process that must be performed in such a filter element.

The object of the present invention is therefore to provide a solution that allows easy removal of the filter element.

According to a first aspect, this object is therefore achieved by a filter device for an extractor hood, wherein the filter device comprises at least one filter element and at least one pivoting device for the pivotable mounting of the filter element to the extractor hood. The filter device is characterized in that the at least one filter element is fastened rigidly to at least one of the pivoting devices via a releasable attachment.

For the purposes of the present invention, a filter device is referred to as a filter device which comprises a filter element and a fastening mechanism for fastening the filter element to the extractor hood. The filter device according to the invention can be used in various types of cooker hoods. According to a preferred embodiment, however, the filter device is used in a flat-screen hood. As attachment of the filter element to the hood of the state of the filter element is referred to, in which the filter element is no longer detached from the hood without the action of the user of the hood. In addition, as will be described in more detail later, a holding device may be provided on the filter device, via which the filter element is held in the operating position in which it covers the air intake opening of the extractor hood. In general, the filter element is in the operating position in a horizontal orientation.

According to the invention, the filter device comprises at least one filter element and at least one pivoting device. As a pivoting device in this case a fastening mechanism is referred to, via which the filter element relative to the hood can be brought into different positions and over which the filter element is attached to the hood. The pivoting device is designed so that the filter element can be attached to the hood above it, that is to say can be held in a position in which the filter element does not detach from the extractor hood without the action of the user of the extractor hood. In addition, the movement of the filter element is guided from a removal position to an operating position and vice versa by the pivoting device. The pivoting device serves for pivotally supporting the filter element or elements on the extractor hood.

According to the invention, more than one filter element can be provided in the filter device. In this case, a pivoting device is preferably associated with each filter element. This means that preferably a filter element is attached to a pivoting device. However, it is also in the context of the invention two or to attach more filter elements to a pivot device or to attach a filter element to two or more pivot devices.

For the sake of clarity, the invention will be described below essentially with reference to a filter device having a filter element and a pivoting device. However, the statements apply as far as applicable in accordance with filter devices with multiple filter elements and / or swivel devices.

The filter device according to the invention is characterized in that the at least one filter element is fastened rigidly to the pivoting device via a releasable attachment. As a releasable attachment in this case an attachment is referred to, which can be solved without the use of tools. As a rigid attachment of the filter element to the pivoting device, a fastening is designated, in which the relative position of the filter element relative to the pivoting device can be changed only in one direction of the surface of the filter element. A pivoting of the filter element with respect to the pivoting movement is prevented by the rigid connection, however.

By the pivoting device is provided separately from the filter element in the filter device according to the invention, the filter element does not form part of the pivotable mounting, as is the case in the prior art. For this reason, the attachment and detachment of the filter element to or from the extractor hood are simplified. In particular, a levering of the filter element is not required and the removal or release of a securing device, which is required in the prior art, can be omitted. In particular, in the structure according to the invention, a securing device can be provided in or on the pivoting device or can be formed by it and can thus remain on the extractor hood when the filter element is removed. In addition, by the attachment of the filter element to the pivoting device is rigid, the pivoting device can be actuated via the filter element and unwanted movement of the filter element relative to the pivoting device is not to be feared. According to a preferred embodiment, the releasable attachment between the filter element and the pivoting device is a latching connection. The latching connection can also be referred to as a snap connection. The releasable attachment may be indirect or immediate. By a locking connection is selected for fastening, on the one hand a simple fastening and releasing the filter element can be realized on the pivoting device. On the other hand, the user receives a haptic feedback on the attachment and release of the filter element at a locking connection. Finally, a locking connection can be realized by easy to produce means, whereby the structure of the filter device is simplified.

Preferably, the latching connection is constructed or is implemented by such latching means in which the latching force and release force is in each case in a direction of the surface of the filter element. The latching force in this case refers to the force that must be applied to the filter element in order to connect this with the pivotal connection. The release force refers to the force that must be applied to the filter element to release the filter element from the pivot device. The latching force in this case preferably represents a compressive force, which is directed from the front of the filter element in the surface of the filter element to the rear. The release force represents a tensile force which is directed from the back of the filter element in the surface of the filter element to the front. Since in the filter device according to the invention thus for releasing the filter element from the pivoting device and thus from the hood no leverage must be used, the release of the filter element of the extractor hood is simplified. In addition, however, ensures a secure hold of the filter element on the pivoting device, which counteracts an uncontrolled dropping of the filter element by the preferably provided latching connection. Only by applying a tensile force on the filter element by the user of the extractor hood, the connection between the pivoting device and the filter element is controlled solved.

Direction information, such as front, back, top or bottom, hereinafter, unless otherwise stated with respect to the filter device used in the introduced in the hood and the operating position state. The operating state here is understood to be the state in which the filter element conceals an intake opening of the extractor hood and, in particular, in this Suction port is held. Preferably, the filter element of the filter device is aligned horizontally in the operating state.

According to a preferred embodiment, the pivoting device has at least one profile rail for receiving at least one fastening region of the filter element. As a rail here a rail is called, which represents an open profile. In particular, the rail is open over its length on one side. According to one embodiment, the rail can thus have a U-shaped or open rectangular cross-section. As a fastening region of the filter element of the part is referred to the filter element, via which the attachment to the pivoting device takes place. The attachment portion may be part of the filter element or may be a separate component attached to the filter element. By using a profile rail, a clamping force can be exerted on the fastening area to be accommodated by the rail itself. Additionally or alternatively, the profile rail can also serve for receiving or holding other parts of the pivoting device due to their open shape. The rail can be made of metal or plastic. In these materials, the production of the rail and thus the filter device according to the invention is particularly simple.

According to a preferred embodiment, the attachment region of the filter element lies in the rear region of the filter element. By this embodiment, the filter element can be introduced from the front into the pivoting device and in particular in a profiled rail of the pivoting device and thus attached to it from the front. As a result, the fastening and loosening of the filter element are further simplified.

According to a preferred embodiment, the attachment region comprises at least one fastening element for attachment to the pivoting device. The fastening element is a separate component to the filter element, which is fastened to the filter element. By instead of a part of the filter element, a separate fastener is used, this can be adapted to the shape and operation of the pivoting device in a simple manner, without that structural changes to the filter element itself must be made. In addition, by providing a mounting area as a separate fastener the Width of the mounting area can be set lower than the width of the filter element. As a result, the force which is necessary for fastening the filter element to the pivoting device, further reduced and also facilitates the release of the filter element of the pivoting device.

According to a preferred embodiment, the at least one fastening element is provided on the rear side of the filter element. The one or more fasteners are preferably rigidly connected to the filter element. The fastening elements can be screwed, for example, to the back of the filter element. The arrangement of the fastener on the back of the filter element has a number of advantages. On the one hand, the filter element usually has a filter frame in which the filter material is held. The back of the filter element is also formed by the frame. Thus, a fastener can be deducted, for example screwed on the back of the filter element in a reliable manner. Another advantage of the arrangement of the fastener or fasteners on the back of the filter element is that a force for attaching the filter element applied from the front is in the same plane as the fastener or fasteners. Thus, the attachment is further simplified.

According to a preferred embodiment, at least one, more preferably at least two connecting elements are provided for engagement with the fastening region of the filter element in the pivoting device. The connecting element preferably represents a component which is separate from the profiled rail and is preferably introduced into the profiled rail at least in regions. It is particularly preferred that the connecting element except for a bearing pin optionally provided thereon, completely received in the rail. This has the advantage that after connecting the filter element to the connecting element, the bottom of the filter device can be formed exclusively by the filter element and the underside of the rail and no gap between the rail and the filter element. An advantage of providing one or more fasteners is that the shape of the mounting rail can be simple. Another advantage of using a separate connecting element to the rail is that this is made of a different material than the rail can. For example, the rail represent a metal rail and the connecting elements may be made of plastic. This embodiment has the advantage that the rail has sufficient stability and the connecting elements in a complex form in a simple manner, for example by injection molding, can be produced.

At least one bearing pin is preferably provided on the pivoting device and preferably on the connecting element, via which the pivoting device is connected to the extractor hood and about which the pivoting device is pivotably mounted. By the one or more bearing pins are provided on the pivoting device, which is detachably connected to the filter element, the attachment of the filter device to the extractor hood is thus not on the filter element but on the separate pivoting device. Thus, the present invention differs significantly from the prior art, in which the attachment of the filter element and the pivoting of the filter element via tabs or pins on the filter element itself.

The bearing pins are preferably provided at the longitudinal ends of the pivoting device. Here, the bearing pins may be provided on end sides of a rail. According to a preferred embodiment, however, the bearing pins are provided on connecting elements, which are received in the rail. In this case, two connecting elements are preferably provided, each with a bearing pin. The bearing pins are aligned so that they protrude beyond the longitudinal ends of the rail when introduced into the rail fasteners. This embodiment has the advantage that on the rail itself no end faces must be provided at the longitudinal ends and therefore has a particularly simple structure. In addition, the attachment of the pivoting device to the extractor hood in this embodiment, in which the bearing pins are provided on connecting elements, simplified. In particular, two connecting elements can first be introduced in each case with the bearing pin provided thereon into corresponding opposite openings on the suction opening of the extractor hood. Subsequently, the rail can be applied to the so-held fasteners and lock with them. Alternatively, it is also possible the connecting elements in the rail in one of bring the longitudinal ends spaced position in which the bearing pins are still in the rail, that does not protrude beyond the longitudinal ends. The rail with the connecting elements can then be brought into the suction opening and the connecting elements are displaced in the direction of the longitudinal ends, whereby the bearing pins protrude beyond the longitudinal ends. The so-projecting bearing pins are thereby introduced into the corresponding openings provided on the extractor hood.

The connecting elements are preferably held in the rail at least by clamping force. Alternatively or additionally, locking devices can preferably also be provided on the connecting elements and the profile rail, by means of which latching the connecting element with the profiled rail and thus held in this. The locking devices act in this case, in particular a release force, which is applied to release the filter element of the pivoting device, contrary.

According to one embodiment, insertion bevels are provided on the pivoting device and / or the filter element. The chamfers may facilitate insertion in the horizontal direction or in the vertical direction. On the pivoting device, the insertion bevels can be provided for example on the rail in the form of an inclined insertion plate. The insertion plate is according to one embodiment, an extension of one of the legs, preferably the upper leg of the rail over at least a portion of the length of the rail. Alternatively or additionally, it is possible to provide the insertion bevels, for example, on the one or more connecting elements. On the filter element, the insertion bevels are provided in particular in the attachment area. In this case, the insertion bevels can be provided on the filter element itself or on a fastening element provided thereon. By providing chamfers, the attachment of the filter element to the pivoting device and thus to the extractor hood is further simplified.

According to a further embodiment, the profiled rail has an edge for abutment with the extractor hood, which is provided at a distance from the opening of the profiled rail on the profiled rail. By providing an edge, the pivoting device can be locked in a defined position or a Pivoting beyond a certain angular position to be prevented. By the edge is provided on the rail, this remains even after removal of the filter element to the hood. In addition, a separate release of the filter element from the stop, which serves as a security device, not required. Thus, the release of the filter element is further simplified. The edge is preferably formed by a corner of the profile rail. Particularly preferably, this corner has a flattening, which serves as a contact surface or stop surface for abutment with the extractor hood. Preferably, therefore, the edge is the upper rear corner of a U-shaped rail. As a corner here the transition between the base and the upper leg of the U-shaped rail is called. The distance between the edge and the pivot axis of the pivoting device is greater than the distance of the upper leg of the rail and the pivot axis. Preferably, the edge is provided on the rail over its entire length. This has the advantage that a secure hold of the pivoting device can be ensured in the removal position and also the shape and thus the production of the rail is simplified.

According to a preferred embodiment, at least one retaining element is provided on the filter element. As a holding element in this case an element is referred to, which holds the filter element in an operating position in the suction opening of the hood together with the pivoting device. As a holding element known from the prior art retractable pins with a handle over which the pins can be operated serve. Preferably, however, the retaining element is provided on the upper side of the filter element and constitutes a so-called push-push element. This element interacts with a counterpart that is provided on the extractor hood. By push-push element with counterpart can be solved with a single application of a compressive force from below to a filter element in the operating position of the hold between the holding element and the counterpart. In a renewed force application, however, the holding element engages with the counterpart, that they are connected to each other and the filter element is held in the operating position. The holding element is preferably arranged in the front region of the filter element, that is to say located in the region of the filter element which lies opposite the fastening region of the filter element. According to a further aspect, the object is achieved by an extractor hood having at least one filter device according to the invention. The construction of the extractor hood is not significantly changed due to the simple structure of the filter device. In particular, receiving openings for bearing pins, which may be provided on a filter element in the prior art, serve for fastening the pivoting device to the extractor hood.

According to a preferred embodiment, the extractor hood is a flat-screen hood. Especially with flat-screen hoods, the advantages of the present invention can be used particularly. As Flachschirmhaube here an extractor hood is referred to, which has a relative to the housing of the hood forward displaceable extract element. In the housing of the hood at least one filter element is arranged, which is also referred to as a rear filter element. In the pull-out element, a further filter element may be arranged, which is also referred to as a front filter element. According to the invention, at least one filter device according to the present invention is thus attached to the extractor hood at least on the housing, but preferably on the housing and on the pull-out element.

In particular, the rear filter element of a flat screen hood is difficult to access for the user of the extractor hood in the rule. By the pivoting device according to the invention, however, the filter element can be brought into an inclined position, which is referred to as removal position, in which the filter element is easily accessible from the front for the user. In the removal position, the filter element is pivoted via the pivoting device relative to the housing of the extractor hood or the extension element with the front edge downwards. In this position, the filter element can be held in the filter device according to the invention, for example via an edge on the rail of the pivoting device.
