Description

[0001] The present invention relates to an extractor device, in particular a ceiling fan device, comprising at least one housing device with at least one intake opening for sucking in air and / or vapors, and at least one blower device, which is arranged at least partially in the housing device. The blower device comprises at least one first and at least one second air inlet opening for admitting air and / or vapors and at least one rotation axis, wherein the first and second air inlet openings are arranged on two opposite sides of the blower device and are each operatively connected to the intake opening. The present invention also relates to a ceiling fan system and a method for operating a ceiling fan system.

[0002] Extractor hoods, downdraft fans, and / or ceiling fans are often arranged and / or installed in the immediate vicinity of a cooking area, i.e., above, next to, behind, and / or even within a hob, to extract the greasy vapors that rise during cooking, thus preventing soiling of the kitchen units and, generally, the development of unpleasant odors. In extractor hoods and ceiling fans, the greasy vapors and / or air that rises, for example, from a hob or from cookware placed on the hob, are typically sucked upwards by a fan, freed of grease particles, and fed into a recirculation and / or exhaust system.

[0003] It is generally advantageous for such extractor hoods to draw in air and / or fumes as efficiently as possible and / or to be designed and positioned in a way that is largely unobtrusive to the user. It is often advantageous for such extractor hoods to require only a small or even very small installation volume, for example, to be able to be integrated sectionally into a ceiling wall and / or a section of a suspended ceiling space, in particular a suspended one, and / or to provide sufficient space for additional equipment and / or kitchen components. It is also generally advantageous for such extractor hoods to produce only low or even very low noise emissions when in operation, so that such extractor hoods are perceived by the user as being of little or essentially no disturbance.

[0004] Conventional extractor hoods operate largely reliably. However, the disadvantage is that they are often not very user-friendly and / or, due to their spatial design and installation volume, are sometimes difficult to install and / or maintain.

[0005] It is therefore the object of the present invention to provide an extractor hood which can be integrated into a small installation volume, in particular at least partially into a ceiling wall, and / or can be operated in a user-friendly, in particular quiet, manner.

[0006] This object is achieved by an extractor device having the features of claim 1, a ceiling ventilation system having the features of claim 14, and the method for operating a ceiling system having the features of claim 15. Preferred developments of the invention are the subject of the dependent claims. Further advantages and features of the invention will become apparent from the exemplary embodiments.

[0007] The extractor device according to the invention, in particular a ceiling fan device, comprises at least one housing device with at least one intake opening for sucking in air and / or vapors, and at least one fan device, which is arranged at least partially in the housing device. The fan device comprises at least one first and at least one second air inlet opening for admitting air and / or vapors, and at least one rotation axis, wherein the first and second air inlet openings are arranged on two opposite sides of the fan device and are each operatively connected to the intake opening.In this case, sucked-in air and / or sucked-in vapor flows from the intake opening to the first air inlet opening through at least one first flow path and from the intake opening to the second air inlet opening through at least one second flow path, wherein the first and the second flow path are of different lengths.

[0008] The intake opening is suitable and designed for sucking air and / or vapors into the housing device.

[0013] The extractor device preferably comprises at least one filter device, in particular with at least one grease filter element, an odor filter element and / or a moisture absorber element.

[0014] In particular, during operation of the extractor unit, air and / or rising vapors are drawn into the housing through the intake opening to the fan unit and are discharged and / or blown out of the fan unit through the air outlet opening. Preferably, the air and / or rising vapors are at least partially filtered by a filter unit.

[0015] In advantageous further developments, the extractor device, in particular the ceiling fan device, is suitable and designed to be operated in a recirculation mode and / or an exhaust air mode.

The fan device of the ceiling fan device is preferably arranged, at least in sections, above or above the ceiling wall. The extractor extraction device is preferably suitable and designed to be integrated, at least in sections, into a suspended ceiling space.

[0017] The present invention has many advantages. A significant advantage is that the sucked-in air and / or vapor flows from the intake opening to the first air inlet opening through at least one first flow path and from the intake opening to the second air inlet opening through at least one second flow path, wherein the first and second flow paths are of different lengths.

[0018] This reduces air turbulence at the intake opening in particular or even essentially eliminates it completely, so that air and / or vapors can be sucked into the housing device particularly effectively and / or quietly.

[0019] Furthermore, this enables a particularly low installation height for the extractor unit, allowing the extractor unit to be integrated into a small or even very small installation volume, particularly with a small vertical dimension. For example, the extractor unit according to the invention can be integrated, at least in sections, into a ceiling wall and / or into a suspended ceiling space above a ceiling wall, particularly a suspended one.

[0020] This also allows the fan device to include a rotating element with a large or even very large diameter, particularly parallel to the intake opening. This makes the fan device of the extractor unit particularly powerful and preferably enables efficient air intake while simultaneously producing low or even very low noise emissions during operation of the extractor unit.

[0021] As a result, the extractor hood according to the invention is particularly user-friendly and / or can be arranged, particularly flexibly, in a small installation space such as a suspended ceiling space.

[0022] Preferably, the intake opening is arranged substantially perpendicular to the rotational axis, so that the drawn-in air flows through the intake opening substantially parallel to the rotational axis. This reduces, in particular, air turbulence at the intake opening or even substantially eliminates it entirely, so that air and / or vapors can be drawn into the housing device particularly effectively and / or quietly.

[0023] Preferably, the axis of rotation is aligned perpendicular to at least the first and / or the second air inlet opening.

[0024] Particularly preferably, the intake opening is arranged substantially parallel to the first and / or second air inlet opening, so that the intake air flows through the intake opening substantially perpendicular to the first and / or second air inlet opening. This enables, in particular, a low installation height for an extractor fan designed as a ceiling fan.

[0025] In expedient further developments, the axis of rotation is aligned perpendicular to at least the first and / or the second air inlet openings.

[0026] Preferably, the intake opening is arranged substantially parallel to the first and / or the second air inlet openings, so that in particular the intake air flows substantially parallel to the axis of rotation through the intake opening.

[0037] Preferably, a ratio of a lateral dimension of the intake opening and a lateral dimension of the blower device, in particular along a (common) direction, is substantially equal to 1, preferably greater than 7 / 6 and / or 7 / 5, preferably greater than 7 / 4 and / or 7 / 3, in particular greater than 7 / 2 or even greater. Depending on the task and design, the ratio of a lateral dimension of the intake opening and a lateral dimension of the blower device can also be less than 1 and / or at least one lateral dimension of the intake opening can be smaller than at least one lateral dimension of the blower device.

[0038] In expedient developments, the fan device comprises at least one rotating element that rotates at least temporarily around the rotation axis, wherein the rotating element has a diameter of more than 146 mm and less than 180 mm, in particular 160 mm.

This allows the extractor device to be connected to a connecting line particularly reliably and easily in order to discharge air and / or vapors particularly reliably.

[0047] In this case, a connecting line is provided in particular by at least one pipe section and / or connecting pipe.

[0048] Preferably, the air outlet opening is suitable and designed to be connected to at least one connecting line with a diameter of substantially 150 mm.

[0055] In the method according to the invention for operating a ceiling fan system, as described above, air and / or vapors are sucked in substantially upwards through the intake opening into the housing device to the first and second air inlet openings of the blower device, so that the sucked-in air and / or vapors flow from the intake opening to the first air inlet openings through at least one first flow path which is shorter than a second flow path of the sucked-in air and / or vapors from the intake opening to the second air inlet opening.

[0056] Preferably, the first flow path may also be longer than the second flow path.

[0057] The method according to the invention also has the previously described advantages of an extractor device according to the invention and a ceiling fan system according to the invention.

[0058] Further advantages and features of the present invention will become apparent from the embodiments which are explained below with reference to the accompanying figures.

[0059] The figures show: Figure 1 shows a purely schematic representation of an embodiment of an extractor extraction device according to the invention in a sectional side view; Figure 2 shows a purely schematic representation of an embodiment of a ceiling fan system according to the invention with an extractor extraction device according to the invention in a sectional side view; Figure 3 shows a purely schematic representation of a further embodiment of a ceiling fan system according to the invention with an extractor extraction device according to the invention in a sectional side view; and Figure 4 shows a purely schematic representation of a further embodiment of a ceiling fan system according to the invention with an extractor extraction device according to the invention in a view from above.

[0060] In Figure 1 An embodiment of an extractor hood device 1 according to the invention is shown purely schematically in a sectional view from the side.

[0061] The extractor device 1 is designed here as a ceiling fan device 100 and is shown purely schematically in an operating position 12, ie, here in a usual and / or practical installation and / or operating situation.

[0062] In the exemplary embodiment shown here, the extractor device 1 comprises a control device 21, a housing device 2 with an intake opening 3 for sucking in air and / or vapors and a fan device 4 arranged in sections in the housing device 2.

[0063] In the exemplary embodiment illustrated here, the intake opening 3 is oriented substantially horizontally and arranged in a lower section 13 of the housing device 2. Depending on the task and design, the intake opening 3 can also be oriented and / or arranged differently in an operating position 12. For example, the intake opening can also be oriented substantially vertically or obliquely and / or arranged in an upper or lateral section of the housing device 2.

[0064] The blower device 4 is arranged essentially directly above the intake opening 3 in the housing device 2 and is provided by a dual-flow radial fan. Thus, the blower device 4 has a first and a second air inlet opening 5, 6 for admitting air and / or vapors into the blower device, which are arranged on two superior sides 8, 9 of the blower device 4 and are each operatively connected to the intake opening 3. The opposite sides 8, 9 of the blower device 4 are aligned essentially parallel to one another, so that the air inlet openings 5, 6 are arranged essentially parallel to one another. Depending on the task and design, the two sides 8, 9 can also be aligned at an angle or not parallel to one another, at least in sections.

[0065] The first air inlet opening 5 is arranged here on a side 9 of the fan device 4, which here faces the intake opening 3. The second air inlet opening 6 is arranged here on a side 8 of the fan device 4, which here faces away from the intake opening 3. Thus, sucked-in air and / or sucked-in vapors flow from the intake opening 3 to the first air inlet opening 5 through a first flow path 10, which is shorter here than a second flow path 11 of the sucked-in air and / or sucked-in vapors from the intake opening 3 to the second air inlet opening 6. Depending on the task and design, it is also possible for the second flow path 11 to be shorter than the first flow path 10. As a result, the extractor extraction device according to the invention, shown here purely schematically, enables particularly user-friendly, in particular quiet operation and / or can be designed to be particularly space-saving.

[0066] In the exemplary embodiment shown here, the air inlet openings 5, 6 are arranged parallel to the suction opening 3, so that in an operating state of the extractor device 1, air and / or vapors are sucked in through the suction opening 3 essentially perpendicular to the first and / or second air inlet opening 5, 6.

[0067] Furthermore, the blower device 4 comprises a rotation axis 7 and a rotation element 16, which rotates around the rotation axis 7 in an operating state of the extractor device.

[0068] The rotation axis 7 is arranged essentially perpendicular to the intake opening 3, so that, in an operating state of the extractor device 1, air and / or vapors are drawn in through the intake opening 3 essentially parallel to the rotation axis. The rotation element 16 has a diameter 17 of essentially 160 mm. Depending on the task and design, the rotation element 16 can also have a larger or smaller diameter 17.

[0069] In the exemplary embodiment shown here, the fan device 4 has a lateral dimension 15, which is smaller than a lateral dimension 14 of the intake opening. In the exemplary embodiment shown here, the fan device 4 is also arranged with its shortest extension along the height 19 of the housing device 2. Thus, the fan device 4 has a dimension along the height 18 in the range of 15 cm to 20 cm. This allows a dimension along the height 19 of the extractor device 1 to be particularly small. Thus, the extractor device 1 has a dimension along the height 19 of essentially 20 cm.

[0070] In the exemplary embodiment shown here, the fan device comprises an air outlet opening 20 for discharging air and / or vapors. The air outlet opening 20 has a substantially circular cross-section and is designed and configured to be connected to a connecting line (not shown in detail here), so that air and / or vapors can be discharged from the fan device 4 into the connecting line.

[0071] In the embodiment shown here, the extractor device 1 is suitable and designed to be operated particularly quietly or with low noise.

[0072] In Figure 2 A ceiling fan system 200 is shown purely schematically in a sectional view from the side.

[0073] In the exemplary embodiment shown here, the ceiling ventilation system 200 comprises a ceiling wall and an extractor device 1 according to the invention with a device frame 201, wherein the extractor device 1 is designed here as a ceiling ventilation device 100. The device frame 201 provides an opening 202.

[0074] As in Figure 1 In the exemplary embodiment shown here, the extractor extraction device 1 comprises a control device 21, a housing device 2 with an intake opening 3 and a fan device 4 with a first and a second air outlet opening 5, 6. In addition, the extractor extraction device 1 comprises a filter device 22, which is assigned to the intake opening 3 here.

[0075] How Figure 1Here, the first and second air outlet openings 5, 6 are arranged on two opposite sides 8, 9 of the blower device 4. The first air inlet opening 5 is arranged here on one side 9 of the blower device 4, which here faces the intake opening 3, and the second air inlet opening 6 is arranged here on one side 8 of the blower device 4, which here faces away from the intake opening 3. Thus, sucked-in air and / or sucked-in vapors flow from the intake opening 3 to the first air inlet opening 5 through a first flow path 10, which is shorter here than a second flow path 11 of the sucked-in air and / or sucked-in vapors from the intake opening 3 to the second air inlet opening 6. Depending on the task and design, it is also possible for the second flow path 11 to be shorter than the first flow path 10.In this case, in addition to the fan unit 4, the device frame 201 is also shown, which can be designed to be particularly flat thanks to the proposed structure. This allows the ceiling fan system, shown here purely schematically, to be integrated at least partially into a small installation space, such as a suspended ceiling space, above a ceiling wall (not shown).

[0076] Thus, the ceiling fan system 200 shown here purely schematically can carry out a method according to the invention for operating a ceiling fan system.

[0077] In Figure 3 is purely schematically the embodiment of the ceiling fan system 200 according to the invention from Figure 2 shown purely schematically in an operating state in a sectional view from the side.

[0078] In the exemplary embodiment shown here, the flow paths of the sucked-in air and / or vapors are indicated purely schematically by arrows. Thus, air and / or vapors are sucked upward through the intake opening 3, with a portion of the sucked-in air and / or vapor flowing via a first flow path 10 from the intake opening 3 to the first air inlet opening 5 into the blower device 4, and another portion of the sucked-in air and / or vapor flowing via a second flow path 11 from the intake opening 3 to the second air inlet opening 6 into the blower device 4. Here, the first flow path 10 is shorter than the second flow path 11. Depending on the task and design, the second flow path 11 can also be shorter than the first flow path 10.

[0079] In Figure 4is a purely schematic further embodiment of ceiling fan systems 200 according to the invention, each with an extractor device 100 according to the invention in different orientations, shown in a view from above.

[0080] As in the Figure 2 and 3 Here, too, each of the extractor units 1, embodied here as a ceiling fan unit 100, comprises a housing unit 2 and a blower unit 4 with a first and a second air inlet opening 5, 6, which are arranged here on two opposite sides 8, 9 of the blower unit 4. Furthermore, each extractor unit 1 shown here comprises an air outlet opening 20 for discharging air and / or vapors from the blower unit 4.

[0081] In each of the Figure 4In the embodiments shown, the blower device 4 is rotated about a rotation axis 7, which is aligned perpendicular to the intake opening 3, so that in each of the Figure 4 illustrated embodiments, the blower device 4 has a different orientation.

[0082] Also, in each of the embodiments shown here, at least one lateral dimension 14, 24 of the intake opening 3 is larger than a lateral dimension 15, 23 of the blower device 4. List of reference symbols
