Description

Technical field

The invention relates to a flat furnishing element, in particular a room divider or a wall covering.

State of the art

Flat furnishing elements of the type mentioned at the outset are widely used, for example, in the design of open-plan offices or larger lounge areas. This improves the feeling of well-being of the people in it through the more pleasant interior design. In particular, if these furnishing elements have a sound absorption area and can thus absorb sound from the environment, these furnishing elements can contribute to improving the well-being of the people by lowering the noise level.

Such furnishing elements thus promote the health of the people in the area and have proven themselves. However, ever higher demands are being made.

Presentation of the invention

It is an object of the present invention to provide a planar furnishing element with a simple construction, which can contribute to improving the well-being and / or health aspects which can be relevant in particular in larger rooms.

This object is achieved according to the invention by the flat furnishing element with the features of claim 1. Accordingly, a flat furnishing element, which is preferably a room divider or a wall covering, is provided with a sound absorption area for absorbing sound (which may be optional - or another functional area) on at least one side of the furnishing element. The furnishing element has an air filter for filtering out particles from the ambient air, an air inlet opening for introducing ambient air and an air outlet opening for discharging filtered air, a suction device, preferably a fan, for sucking ambient air through the air inlet opening to flow through the air filter and an air duct for Lead the ambient air within the furnishing element at least in sections, preferably completely, between the air inlet opening and the air outlet opening. The air filter, the suction device and the air duct can be referred to as a filter unit.

The invention is based on the idea of providing a flat furnishing element in addition to a primary function (sound absorption) with a further function, namely filtering the ambient air. The ambient air is passed through the air duct through the furnishing element, i.e. within the furnishing element, at least in sections and preferably completely. By filtering the ambient air with the help of the furnishing element, an additional health aspect can be taken into account, namely the improvement of the quality of the ambient air. In particular, the health aspect can be improved by air filtering, so that pathogens, for example viruses, can be filtered out of the ambient air and thus the risk of infection and the spread of diseases can be reduced.

One advantage is that in addition to the primary function (sound absorption), the furnishing element can take on the additional function of air filtering and, for example, no separate air filter device has to be provided. This is also advantageous from an optical point of view and / or for reasons of space. The function of air filtering is integrated into the furnishing element. In addition to its primary function (sound absorption), the furnishing element then has an integrated air filter.

In the event that the flat furnishing element has a sound absorption area for absorbing sound, this primary function of the furnishing element is combined with the further function of air filtering. In this case, it may be advantageous that noises caused by the air filtering are also absorbed with the aid of the sound absorption area of the furnishing element. In other words, it is precisely in combination with sound-absorbing properties of the furnishing element that there is the advantage that possible noises caused by the air filtering are absorbed again.

The planar furnishing element can be characterized by its planar extent within a plane.

The furnishing element can be called an acoustic element. The furnishing element is preferably movable, in particular a room divider. The furnishing element can be a partition. The furnishing element can be fixed or mobile. The furnishing element can have a base, in particular if it is designed as a movable furnishing element.

An embodiment of the furnishing element in which the primary functional area is a sound absorption area. It is also conceivable that there is no sound absorption area in the furnishing element according to the invention. Instead, another primary functional area can be provided.

The sound absorption area is set up to absorb sound. In particular, the structure and / or the material of the sound absorption area is designed accordingly. The sound absorption area can be set up in such a way that a sound absorption value α _W of at least 0.5, preferably at least 0.7, more preferably at least 0.8, most preferably at least 0.90 (absorber class A and or B )(according to DIN EN ISO 11654 ) is reached. The planar furnishing element preferably has a planar sound absorption area, so that planar absorption of sound is possible.

The suction device can be a fan. The suction device can also have a first subunit, which essentially serves as an air duct, for example, and a second subunit that is in fluid communication with the first subunit and is arranged outside the sound absorption area and serves to generate the air flow. A radial fan can be used as a fan, for example an EC radial ventilator RadiCal from ebmpapst. An axial fan is also conceivable.

A particulate filter or so-called HEPA (High Efficiency Particulate Air) filter, for example from camfil, can be used as the filter. A filter can consist of several sub-filters; several filters can be provided. The particles can be solid or liquid particles contained in the ambient air. The particles can include Viruses, pollen, bacteria and / or fungi. The filter is particularly designed to filter out particles with a diameter between 0.01 μm to 200 μm.

An opening can have several partial openings, i.e. both the air inlet opening and / or the air outlet opening can have a plurality of partial openings.

Particularly advantageous developments of the invention are specified in the dependent claims.

The air inlet opening can be at least partially surrounded by the sound absorption area or can be arranged on the same side of the furnishing element as the sound absorption area. As an alternative or in addition, the suction device, the air filter and / or the air duct can lie at least in sections within the sound absorption area. This enables a particularly good integration of air filtering with sound absorption. In particular, a desired area can then not only be sound-absorbing and thus sound-reduced, but also the air present in this area is cleaned. This makes it possible to simultaneously improve the impairments that can affect a person in this area.

The air filter is preferably a surface filter and is preferably arranged on the surface of the furnishing element and / or in the air inlet opening. In a preferred embodiment, the air filter can be arranged essentially flush with the sound absorption area. In other words, the air filter can be provided directly at the air inlet opening, so that the air is filtered immediately upon entry into the furnishing element. This has the advantage, for example, that unpurified ambient air is only present outside the furnishing element, but not inside.

The size or area of the air inlet opening and / or the air filter, when it is inserted in the air inlet opening, can be at least one tenth of the area of the sound absorption area, preferably at least one fifth of the area of the sound absorption area. The reference to the area of the extension of the furnishing element in the plane is also conceivable, so that the surface of the air inlet opening and / or the air filter is at least one tenth of the surface of the furnishing element, preferably at least one fifth of the surface of the furnishing element.

The area of the air inlet opening and / or the air filter can preferably be at least 0.2 m ² , more preferably at least 0.6 m ² , more preferably on both sides.

Such a size ratio can contribute to a sufficient amount of ambient air being filtered and, in particular, can enable sufficient noise reduction with at the same time sufficient air filtering per furnishing element.

In a preferred embodiment, the furnishing element has a decorative layer, which is preferably located substantially above or in front of the sound absorption area. This decorative layer or another decorative layer is preferably also arranged above the air inlet opening and / or the air filter or the filter unit. The decorative layer allows a pleasing appearance of the furnishing element to be achieved, so that not only can the well-being be improved by sound absorption and air filtering, but also the aesthetic feeling can be improved can be. The decorative layer can not only be located in the sound absorption area, but also above the filter unit, in particular also above the air inlet opening. This improves the overall optical picture and helps to inconspicuously integrate the filter function into the furnishing element.

The air inlet opening or the air filter do not have to be completely exposed, but can be at least partially covered by the decorative layer. The decorative layer can also have a function that goes beyond the aesthetic aspect and in particular can also contribute to sound absorption. The decorative layer does not have to be continuous, but can consist of several parts or can be designed differently.

The air outlet opening is preferably arranged outside the sound absorption area or facing away from the sound absorption area. It is further preferred that the air outlet opening faces away from the air inlet opening and / or is arranged at a distance from the air inlet opening. It can thereby be achieved that the air is discharged through the air outlet opening at a point on which the furnishing element is not intended to act predominantly. For example, the dedicated surrounding area can be improved for a person who is in the vicinity of the sound absorption area, where the air inlet opening is also arranged, so that this person benefits from the sound absorption and the removal of contaminated ambient air. The cleaned air does not have to be output immediately again in this dedicated surrounding area, since this could manifest itself, for example, as an undesirable draft of air for the person in this area. It is preferred that the air outlet opening and the air inlet opening are located at different locations on the furnishing element.

The air outlet opening can define the air outlet from the furnishing element, but does not necessarily imply the return to the environment directly at the air outlet. In particular, it is conceivable that an air path, for example a pipe, is connected to the air outlet opening, which guides the ambient air away from the furnishing element before the air is released to the environment at another location.

The air duct is preferably widened, at least in sections, towards the air outlet opening, preferably funnel-shaped or conical; the volume defined by the air duct can increase in the flow direction, the volume of the air duct at the air outlet opening preferably being at least 1.2 times, more preferably at least 1.5 times, the volume of the air duct at the suction device . Due to the increase in the volume of the air duct to the air outlet opening, the outlet speed of the air at the air outlet opening decreases. This can reduce air noise.

Alternatively or additionally, the air outlet opening can have at least an area of 0.05 mm ² , preferably at least 0.1 mm2, and / or at least 1/4, preferably at least 1/3, of the external dimension of the furnishing element in the plane of its extent (height or width ).

The air duct, preferably towards the air outlet opening and / or between the suction device and the air outlet opening, can be set up, at least in sections, to have a sound-absorbing and / or sound-absorbing (sound-absorbing) effect. This has the advantage that noises caused by the air filtering do not represent any additional noise pollution for the surroundings, since these noises do not leave the furnishing element. In a special embodiment, the air duct can have projections or one or more projections which protrude into the air flow in such a way that the air flow is deflected. The air duct can also be angled in order to effect the desired deflection of the guided air. For example, a meandering course of the air flow is conceivable. Protrusions may protrude from the surface of the air duct from opposite sides, for example.

It is conceivable that the air duct has projections which are set up to divert the air and / or to act as sound absorbers and / or sound absorbers. For example, several horizontal lines of such projections are conceivable, which can be designed as horizontal plates. In the case of a conical air duct to the air outlet opening, the number and / or length of these projections towards the air outlet can increase.

It is preferred that the filter unit or its components air duct, air filter and suction device are structurally separated from the sound absorption area. The filter unit can be viewed as a separate or self-contained unit. The filter unit can be surrounded by a housing. In other words, the air duct, the air filter and the suction device can have a common housing, which is preferably arranged within the device element. This allows a spatial and functional separation between the filter unit and the rest of the furnishing element to be achieved.

The air duct can be made of wood, for example. The air duct can completely or partially enclose the air flow. This can in particular mean that the air duct between the air inlet opening and the air outlet opening does not run through sound-absorbing material.

This helps ensure that the sound absorption is not exposed to any adverse effects that could be caused by the passage of the ambient air. For example, this can prevent particles contained in the air from depositing more strongly on the sound absorption material or the sound absorption structure and possibly impairing the sound absorption properties.

The suction device is preferably arranged at least partially or completely within the device element. This enables a compact implementation of the furnishing element according to the invention. However, it is not excluded that the suction device is located outside the main body of the furnishing element, in particular outside the planar extent of the furnishing element. The suction device may be arranged outside the sound absorption area and may even be arranged outside the main body of the furnishing element and be in fluid communication with the main body of the furnishing element.

When viewed in the direction of flow, the air filter can be arranged before or after the suction device. In other words, the order of the air filter and suction device can be selected.

It is preferred that the direction of flow of the air between the air inlet opening and the air outlet opening lies essentially in the plane spanned by the device element when the device element is used. This has the advantage that the components for air filtering, in particular the air filter and the suction device, can be arranged in one plane. This enables the components of the filter unit to be optimally integrated into the rest of the furnishing element and in particular to “hide” the filter unit in the furnishing element, that is to say an inconspicuous integration, which essentially does not result in any external changes to the furnishing element compared to a furnishing element without a filter unit.

However, it is not excluded that the air inlet opening and the air outlet opening are arranged in such a way that the direction of flow of the air between these two openings is essentially perpendicular to the plane of the furnishing element, that is to say through the element (viewed in depth). This could be achieved in particular with thicker furnishing elements.

An embodiment is also conceivable in which the air inlet opening and the air outlet opening are arranged on different sides of the furnishing element. This has the advantage that the cleaned air can flow out to another side.

The air inlet and air outlet opening can be arranged at the top or bottom or, for example, left and right of the furnishing element.

The air inlet opening and / or the air filter can be arranged in the upper region, in the middle region or in the lower region of the furnishing element.

The furnishing element can have a plurality of air inlet openings and / or a plurality of air filters. In a preferred embodiment, two air inlet openings and preferably also at least two air filters are provided, which are optionally not congruently arranged one above the other and / or are arranged at least in sections or completely offset from one another. This has the advantage that a larger area is available for filtering, i.e. more ambient air can be filtered, while the filter unit is designed to save space. This arrangement therefore enables a compact implementation.

When using the furnishing element, this can mean that the two air inlet openings and the two air filters, which should preferably effect air filtering on different sides of the furnishing element, are arranged laterally offset in the furnishing element.

If the sound absorption area extends at least in sections over the filter unit, the sound absorption properties of the furnishing element can be kept as high as possible unaffected by the additional provision of the filter unit.

In particular, an embodiment is contemplated in which the furnishing element has an air inlet opening on two preferably opposite sides, in which an air filter is also arranged in each case. This enables effective air purification of a larger area of space because the furnishing element can effect air purification on two sides of the furnishing element.

The furnishing element can have at least two air inlet openings, optionally also two air filters, and a common suction device, optionally also a common air duct. These are preferably arranged in a common housing.

The underlying filter unit then also has two opposite sides, the air inlet openings each being aligned on different sides.

This enables a compact design of a filter unit or a furnishing element which can clean two different spatial directions or two areas separated from one another. For example, the number of required furnishing elements can be reduced with a filter unit, since, for example, only every second furnishing element must also have a filter unit according to the invention in addition to the sound-absorbing properties.

Further features and advantages of the invention will become apparent from the following detailed description.

Detailed description of preferred embodiments

Preferred embodiments of the present invention will hereinafter be described in detail with reference to the accompanying drawings.

The 1a shows a flat furnishing element according to the invention 1 , which is designed as a room divider. The flat furnishing element 1 extends essentially in the plane E which the paper plane in 1a is.

The flat furnishing element 1 has a sound absorption area 2nd on the website 1a that is used to absorb sound from the environment. The furnishing element 1 has an air inlet opening 4th on, can be introduced through the ambient air. This opening 4th can have a recess in the furnishing element 1 represent.

The furnishing element 1 has a decorative layer 8th on that over the sound absorption area 2nd extends. The decorative layer 8th can also continue through the air inlet opening 4th or extend over a further part of the filter unit.

The air inlet opening 4th into which the air filter 3rd is used is at least partially from the sound absorption area 2nd surround. The air inlet opening 4th lies on the same side 1a of the furnishing element 1 like the sound absorption area 2nd . Out 1a it can also be seen that the area of the air inlet opening 4th or the air filter 3rd more than a tenth and more than a fifth of the area of the sound absorption area 2nd is.

The 1b shows in two sectional views that the furnishing element 1 a frame 6 having. The furnishing element points in addition to the frame 6 a sound absorber (not shown), for example a surface structure which is set up to absorb sound, optionally a textile surface or textile layer (not shown) and further optionally the decorative layer 8th that can represent a design surface.

In 1b are not an air filter 3rd and no suction device 5 shown, but the air filter holder 12th to hold the air filter 3rd and the aspirator receptacle 13 to accommodate the suction device 5 . The air outlet 10th is used to discharge filtered air.

As from the 1b is the air filter to be used 3rd to one side, namely the side pointing to the left 1a arranged in the right sectional view, so from this side 1a the air through the air inlet opening 4th can be sucked. The suction effect at the air inlet opening 4th is through the suction device 5 generated that in the recording 13 is arranged. After the already cleaned air through the suction device 5 has flowed through it, this is via the air outlet opening 10th returned to the environment.

One advantage of the arrangement is that the ambient air passes through the filter first 3rd Flows through before it flows through the rest of the filter unit, is that only cleaned or filtered air is guided in the filter unit. This prevents, for example, particles that to be filtered out, precipitate within the filter unit. If a filter 4th inside the furnishing element 1 is arranged, would be upstream to the filter 4th First there is unfiltered air in the filter unit. An advantage for such an embodiment is that the air inlet opening 4th can be made smaller if the air filter 3rd inside the furnishing element 1 is arranged and not in the air inlet opening 4th .

1c shows arrows showing the direction of flow S hint of the air inside the furnishing element. The ambient air is through the air filter 3rd sucked in, located at the air inlet opening 4th is located, and then enters the suction device 5 a, which is for example a fan. The suction device 5 serves to suck in ambient air through the air inlet opening 4th and leads to flow through the air filter 3rd with air. The air exits the fan 5 off again and is then through the air outlet 10th from the furnishing element 1 led out. In this embodiment in 1c is the air filter 3rd in the direction of flow S the air viewed in front of the intake device 5 . The flow direction S the air between the air inlet opening 4th or between the air filter 3rd and the air outlet opening 10th lies essentially within that of the furnishing element 1 spanned level E .

1d shows a sectional view of the filter unit, similar to that shown in 1b is shown on the right. There are bearings in it 7 shown that between the air filter 3rd and the housing 11 , which surrounds the filter unit, and the suction device 5 and the housing 11 are arranged. The bearings 7 are preferably compliant, for example rubber-like parts, by means of which the air filter 3rd and the suction device 5 with the housing 11 are connected. In these sectional views are the air filter 3rd and the suction device 5 (horizontally) arranged one above the other.

Through the housing 11 the filter unit is structurally from the sound absorption area 2nd Cut. In the embodiment shown, the suction device 5 completely within the furnishing element 1 arranged.

The air outlet 10th is how out 1b can be seen outside the sound absorption range 2nd arranged and thus from the sound absorption area 2nd turned away. At the same time is the air outlet opening 10th from the air inlet opening 4th turned away.

In the in the 1 The embodiment shown is an air duct 9 minimally designed and can, for example, between the suction device 5 and the air outlet opening 10th be identified, see 1c . This air duct serves to guide the ambient air within the furnishing element.

The air filter 3rd is a surface filter and is on the surface of the furnishing element 1 arranged. Especially from 1b right side shows that the air inlet opening and the area filter 3rd flush with the sound absorption area 2nd are arranged. In other words, the air filter is standing 3rd preferably not from the sound absorption area 2nd in front.

In the in the 2nd Embodiments shown are two air filters 3rd and 3 ' as well as two air inlet openings 4th and 4 ' in front. Each on one side 1a , 1b there is an air filter and an air inlet opening. The left view in 2a shows the page 1a of the furnishing element 1 with the air filter 3rd and the air inlet opening 4th , and the right side of 2a shows the page 1b of the furnishing element 1 with the air filter 3 ' and the air inlet opening 4 ' . On both sides 1a and 1b is the decorative layer 8th appropriate. The two opposite sides 1a and 1b each extend along the plane E .

The decorative layer 8th extends over the suction device in each case 5 as well as the air duct 9 . In the area of the air filter 3rd the decorative layer is not provided, but can be provided.

2 B shows a sectional view of the in 2a illustrated furnishing element 1 , along a plane E . The furnishing element 1 shows the two air filter receptacles inside 12th and 12 ' on taking the picture 12th to hold the air filter 3rd serves and the recording 12 ' to hold the air filter 3 ' serves.

The 2 B shows just like that 1b a sectional view of the interior of the furnishing element 1 . The two air intake openings 4th and 4 ' are exactly like the two air filter mounts 12th and 12 ' staggered or arranged in time. They are therefore not congruent.

In the in the 2nd The embodiment shown are a common suction device 5 as well as a common air duct 9 intended. That means a single air duct 9 and a single air outlet 10th as well as a single suction device 5 are intended for the joint processing of the ambient air through the two air filters 3rd and 3 ' was sucked in. There is a common housing for these elements 11 provided, in which the components of the filter unit are accommodated. The housing 11 is again within the frame 6 of the furnishing element 1 arranged.

The air duct 9 guides the air from both air inlet openings 4th , 4 ' or both air filters 3rd , 3 ' together and then to the suction device 5 that are in the intake intake 13 is included. The air duct 9 then sits essentially perpendicular to the air outlet opening 10th continued, especially with a constant volume / cross-section. The air duct 9 points at this point, that is between the suction device 5 and the air outlet opening 10th , sound absorbing and / or sound absorbing (sound absorbing) properties. Multiple tabs 9a are provided in the air duct 9 protrude into it and redirect the air inside. Also an angled version of the air duct 9 is alternatively or additionally possible. Of course, this type of airflow can 9 even with only one air filter 4th and an air inlet opening 3rd , for example the embodiment of 1 , be provided.

In the in 3rd The embodiment shown defines the air duct 9 an increasing volume of air; the cross section of the air duct takes 9 conical or funnel-shaped in the direction of flow S to. For example, the air duct (after the suction device 5 ) be designed so that the volume of air through the air duct 9 is defined or recorded, increases to at least 1.2 times, preferably at least 1.5 times, in the air duct. The air duct 10th can at least partially, in particular to the air outlet opening 10th as a funnel or cone (at least two-dimensional, ie viewed in a sectional view). The air duct 10th can be of the width C, which is the width of the air duct after the suction device 5 describes to width B at the air outlet 10th to accept. The ratio B / C can be at least 1.2 or at least 1.5.

The tabs 9a can be provided to redirect the air and / or to act as a silencer and / or silencer (sound absorber). For example, there are several horizontal rows of such protrusions 9a conceivable, which can be designed as horizontal plates. In the case of a conical air duct 9 to the air outlet opening 10th the number and / or length of these projections can be used 9a increase towards the air outlet. In the 3rd three rows of tabs with one, two and three tabs per row are shown.

Based on an external dimension A (Height or width) of the furnishing element 1 in the plane E its proportion can be the proportion of the air outlet opening 10th be between 1/3 and 1/2. That is, the ratio between the width B the air outlet 10th and the outer dimension A is between 1/3 and 1/2.

Of course, this type of airflow can 9 and / or the protrusions 9a even with only one air filter 4th and an air inlet opening 3rd , for example the embodiment of 1 , be provided.

The described embodiments not only absorb sound, but also filter out impurities or particles from the ambient air. This improves the air quality, which promotes the health aspect and also increases the well-being of the people concerned. In particular, this enables pathogens, such as viruses or bacteria, to be filtered out, and can thus contribute to a healthier environment and prevention of the spread of diseases, in particular by droplet infection.
