Description

Ventilation device for generating uniform fluid flows and a drive unit for such a device

Technical area

The invention relates to a device for generating fluid flows, in particular ventilation devices for generating air currents, and drive devices for generating superimposed rotational movements of active elements, in particular for such devices for generating fluid flows.

State of the art

Today's table, floor and ceiling fans are mostly constructed as axial fans, wherein the axis of rotation of the axial impeller runs parallel or axially to the air flow. The air is moved by the axial impeller. Axial fans have comparatively small dimensions with relatively high, promoted air flow. Fans usually have no housing for compression (pressure ratio between intake and discharge side> 1). Thus, such caseless turbomachines are actually propeller machines.

Fans for the living and working area generally have certain disadvantages. In general, propeller fans usually produce too much directed airflow. The relevant measure of the fan's strength is primarily the volume of air that can be transported per unit of time. As a rule, much more air is circulated than needed; unnecessarily high energy costs are incurred.

The fast air flow inflates the user directly, which is often perceived as unpleasant, especially in the facial area. Since a lot of dust and germs are spun around in the room due to the large air flow, health problems can arise. Because the prime mover rotates at high speed and the air is chopped up by the propellers, noise is generated and annoying, which is disturbing, especially at night and in quiet places.

Fans usually have a grid on, as protection against injury from the rapidly rotating rotor blades. However, they are dangerous for young children, for example, because the grids are not tight enough. Attempts have been made to develop alternative ventilation devices. For example, DE 2005050055 shows a device in which a fan is pivoted linearly. An asymmetrical and flexible design of the fan creates an airflow in a certain direction. To change the direction, the whole device has to be turned.

US 201 0/0226751 A1 shows a ventilation device in the form of a standing fan, in which air is sucked through openings in the support column and pumped into an annular nozzle, where it emerges in the form of an annular primary air flow. The air stream carries more air with it, it creates a directed airflow. Such a device has no accessible, fast moving parts and is therefore less dangerous. However, there are problems with the noise generated by the high-speed fan for the promotion of the primary air flow on the one hand and on the other hand, due to discharge noise at the nozzle. The airflow is also strong because the system stops working at lower flow rates.

Object of the invention

The object of the invention is to provide a device for generating fluid flows, in particular a ventilation device which does not have the above-mentioned and other disadvantages of the prior art.

In particular, such a ventilation device should have low energy consumption and be as quiet as possible.

Another object of the invention is to provide a ventilation device which does not require fast moving parts and does not present a risk of injury.

It is also an object of the invention to provide advantageous drive devices for generating superimposed rotational movements of active elements. In particular, such a drive device should be suitable for driving a ventilation device according to the invention.

Such a drive device should allow a compact design. It should cause minimal noise emissions and low energy consumption. Such a drive device should be inexpensive and easy to produce, and consist of as few components.

Advantageously, the device is a change in the transmission ratio, respectively. allow flexible control of the two rotational movements during operation.

These and other objects are achieved by a ventilation device according to the invention and a drive device according to the invention according to the independent claims. Further advantageous embodiments are given in the dependent claims.

Presentation of the invention

The present invention is a device that produces a gentle, directional and adjustable flow in a fluid, particularly air. Such an inventive device can be used wherever there is a need for a gentle, directed and adjustable air flow. As an air flow machine, the device is particularly suitable for use in residential, working and public areas for the purpose of direct cooling of one or more people by means of air flow or generally to promote air circulation in a room.

In a ventilation device according to the invention, a directed air flow is achieved by superimposed movements of one or more paddles and an associated rotary plate. testifies. The rotary plate rotates about its own vertical axis, which in turn is orthogonal to the generated flow axis. The offset to the rotary plate vertical axis and arranged at a certain angle to paddle rotate per revolution of the rotary plate half a turn about its own vertical axis, but in the opposite direction to the rotary plate rotation. This superimposed movement causes a certain mass of air to be picked up and accelerated over the paddle surface and discharged in the direction orthogonal to the paddle surface in the direction of rotation.

An apparatus according to the invention for producing a directed fluid flow, in particular a directed air flow, by moving an active element with an active surface in a fluid, comprises a support structure; a rotation structure rotatably mounted with respect to the support structure about a first rotation axis; and at least one on the rotation structure about a second axis of rotation rotatably mounted active element having an active surface. The at least one active element is operatively connected to the rotary structure and the support structure in such a way that upon rotation of the rotary structure with respect to the support structure about the first axis of rotation at a first rotational frequency, the at least one active element rotates at a second rotational speed with respect to the rotational structure the second axis of rotation rotates. The ratio between the first and second rotational frequency is greater than 1. Preferably, the ratio is> 1 .5, and more preferably> 1 .7.

The ratio between the first and second rotational frequency is advantageously less than 3, preferably

<2.5, and more preferably <2.25.

More preferably, the ratio between the first and second rotational frequency is between 1 .9 and 2.1, and particularly preferably at 2, which corresponds to a constant effective direction. A ratio not equal to 2 again has the advantage that the effective direction is not constant.

In this embodiment, the rotary structure and the support structure are operatively connected such that upon rotation of the rotary structure about the first axis in a certain angular position, the active surface of the paddle is arranged radially relative to the rotary structure, so that the active surface moves frontally in the air. In this position, the active element has the maximum effect, since its active surface moves perpendicular to the air. The normal of the active surface of the active element in the said position defines the entire effective direction of the device. The respective angular position can be defined by the fact that in this position the normal of the active surface is parallel to the tangent of a circle which is described by you moving the intersection of the second axis of rotation with a normal plane to the first axis of rotation.

In an angular position shifted by 1 80 °, the active surface of the paddle is arranged tangentially to the rotary structure, so that the effective surface i essentially offers no air resistance.

Preferably, the active elements are configured as substantially flat paddles.

Such a device can be implemented in various embodiments and equipped with different on - Stellmöglichkeiten for the user. The device works with low energy effort and with minimal noise. The wind flow is generated by a special arrangement and movement of a paddle device with one or more paddles. The generation of the movement of the device and the paddle can be done with different transmission variants.

The device preferably rotates slower than conventional fans, which ensures application safety, especially for children. Certain embodiments can be automatically blocked or turned off when external force is applied to the paddles.

The device according to the invention is scalable and can be designed in different sizes, which makes the realization of e.g. as a miniature, table, floor, wall and ceiling fan allows. The device can be positioned lying, standing or hanging while the direction of action remains the same.

In an advantageous embodiment of a device according to the invention, the second direction of rotation is equal to the first direction of rotation. This is related to an external observer. In the reference system of the rotation structure, however, the at least one active element would rotate in an opposite direction. While the first view is important for understanding the relationship between time-dependent direction of action and frequency ratio, the second view is relevant to understanding the transmission of rotational motion between pivot structure and active elements.

In another advantageous embodiment of a device according to the invention, the first axis of rotation of the rotary structure and the second axis of rotation of the active elements are parallel.

In another embodiment, the angle between the first axis of rotation of the rotary structure and the second axis of rotation of the active elements is less than 90 °, preferably less than 45 °, more preferably less than 30 °.

The angle between the paddle axis and the rotation axis of the rotary plate can be configured in the off state, for example by brackets with different angles on the rotary plate. The bracket angle can also be changed during operation with an additional drive machine or a mechanical gear and a set screw.

The flow rate of the airflow may be in stages or stepless within certain limits

Off state can be configured and / or adjusted in operation by increasing the speed of the rotary plate drive. The characteristic of the flow can be configured in the off-state, by replacing the paddles, which can have different shapes and sizes (and thus attack surface) or material properties (elastic, rigid). A more constant air flow or a higher flow rate at the same speed can be achieved by increasing the number of paddles. This also has an aesthetic effect.

The effective direction, ie the direction of the generated air flow, can be changed automatically during operation in the horizontal, and for example in a certain cadence over the full 360 ° order rotate the vertical axis of the rotary plate. The device thus generates in such a rotation mode, a directed air flow whose direction of action rotates once in a certain time by 360 °. The speed of this rotation and the direction of rotation can be configured in the off state, or set during operation, or provided in a fixed configuration. For example, the gear ratio can be chosen not equal to 2: 1, or it can be provided an additional drive. A change of the flow direction by 1 80 ° can also be done by reversing the direction of rotation of the rotary structure and the active elements. At a ratio not equal to 2: 1, the direction of rotation of the effective direction is thereby reversed.

Also possible is a pivoting of the generated flow direction in a certain angular range. The device covers in such an oscillation mode a wider range of angles, as known from conventional fans whose rotor is also often pivotable. In contrast to these conventional devices, however, it is not necessary to pivot the entire device, but only the alignment of the active elements.

If a time-dependent change of the flow direction over a ratio not equal to 2: 1 is to be obtained, then the change in the flow direction results from the following relationship: The first rotational frequency of the rotary structure is f _{1 f} and the second rotational frequency of the active element is f ₂ , with a Ratio R = f-, / f ₂ . This results in the rotation angle β of the rotary structure and the angle of rotation of the active element α, the ratio R = ß / α. In this case, the angle β, α = 0 ° is a rotation angle at which the active element is in the position with maximum active power at which the normal of the active surface as described above defines the effective direction.

If R is not equal to 2, with R = 2 + d, then there is a change in the effective direction by an angle δ. If, for β = 0 °, the active element is perpendicular to the direction of action, and if β 'is the angle of rotation for which an active element is perpendicular to the new direction of action, with β' + δ = 360 °, β '= α must apply for this rotation angle '+ 1 80 °. At the same time, we always have ß '= R * a. As a result, after deformation δ = -180 ° * ([R-2] / [R-1]), or δ = 1 80 ° * (- d / [1 + d]). For small d «1 this then yields δ 1 80 ° * (-d).

In order to reach the angular position β ', the rotation structure = (β' / 360 °) * (1 / f-,). The angular frequency of the effective direction is thus 360 ° * f _w = | δ | / = | δ / [(1-δ / 360 °)] | * f-,. The frequency of the change of direction of effect is thus f _w = f _n * | δ / (360 ° -δ) |, or for small d 1: f _w f-, * (| ö / 360 ° |) = (| d / 2 |) * f ₁ .

If, for example, R = 1.99 (or R = 2.01), and thus d = -0.01 (or d = 0.01), and the rotation structure rotates at a frequency of ^ = 20 rpm, then δ = 1 80 ° * (0.01 / 1 .01) = 1 .8 ° (or - 1 .8 °). The effective direction rotates at the frequency f _w 0.005 * 20 rpm = 0.1 rpm. Every 1 0 minutes, the effective direction rotates once around the first axis of rotation. With R = 1 .9 or 2.1 already results f _w 0.05 * 20 U / min = 1 U / min. This means that every minute the direction of action turns 360 °. If R is even R = 1 .8 (or R = 2.2), then f _w = 2.2 rpm or 1 .8 rpm.

In order for an effective air flow to occur, it is necessary that active surfaces act several times with a certain direction of action, so that a corresponding movement in the fluid can result. Accordingly, the ratio of the two rotation frequencies should be. R = f -, / f ₂ do not deviate too much from 2. The more active elements a device has, the greater the number of active surfaces that act per revolution of the turntable in the effective direction, and the stronger the resulting air flow. The same applies to larger effective areas. Accordingly, in such a case, the deviation of the ratio of 2 can be chosen larger, and yet an air flow can be generated. In the above example of a device according to the invention with an active element and with f-, = 20 U / min acts approximately every 3 seconds, an active element in the direction of action and pushes air in front of him. The "effective frequency" is thus 1/3 Hz. In a device with two active elements this happens every 1 .5 s, and with three active elements every second (active frequency 1 Hz), etc.

The rotational frequency of the effective direction should advantageously be at least eight times smaller than the rotational frequency of the rotary structure, so that a directional air flow according to the invention can arise, A = f w / f 1 1/8. This corresponds back to a rotation angle δ 360 ° A / (A + 1) = 40 °, or -δ 360 ° A / (A-1) = 51 °. This again corresponds to a deviation -d 0.28 or d 0.22. R should be within the range of approximately 1.72 to approximately 2.22.

In the vertical (with the device upright), the wind direction can be configured over a certain off-state angle and / or adjusted in operation, e.g. with an electric drive, this can be stored, for example, the complete device except the bottom plate on a rotatable horizontal axis.

Advantageously, in an inventive device, the at least one active element on a rotationally fixed or rotationally effective connected to this drive wheel, which is rotationally connected to the support structure. Particularly advantageous in such an embodiment, the drive wheels of the active elements via V-belt and / or idler wheels are rotationally connected to a central wheel, said central wheel relative to the support structure fixed or reversibly lockable. Alternatively, the drive wheels of the active elements are particularly advantageous rotatably connected to a ring gear, said ring gear is fixedly disposed relative to the support structure or reversibly lockable.

In the abovementioned devices according to the invention, the actuation of the active elements is advantageously carried out by a drive motor which rotates the rotary structure relative to the support structure.

The actuation of an active element can be effected by a direct drive motor, which rotates the active element, the drive wheel relative to the rotary structure. A further advantageous embodiment of a device according to the invention has at least one drive unit, wherein the rotary structure and the at least one active element are rotationally connected to a drive unit; and a central gear rotatably connected to the at least one operative element and disposed coaxially with the first axis of rotation, said central gear being rotatable about the first axis of rotation with respect to the support structure and the rotary structure. Particularly advantageously, the central wheel and the rotary structure is driven by a common drive unit, or driven by two different drive units. The central wheel and the rotary structure may have different rotational speeds at the same rotational speed of the drive unit.

Two or more coupling units can be provided, with which the at least one drive unit with the central wheel and the rotary structure are rotationally connectable, wherein the two or more coupling units are alternately activated. In such a variant, two or more coupling units advantageously produce different speed ratios between the central wheel and the rotary structure and / or between the central wheel and the drive unit and / or between the rotary structure and the drive unit. Particularly advantageous two coupling units are provided, between which by switching the direction of rotation of the drive unit can be switched back and forth. Preferably, the coupling units are designed such that the directions of rotation of the central wheel and the rotary structure (5) are independent of the direction of rotation of the drive unit.

Another advantageous variant of a device according to the invention has an auxiliary drive and an addition gearbox with a sun gear, a ring gear and a planet carrier device rotatably arranged between the ring gear and the sun gear. On the Planetenträger- planet gears are rotatably arranged, which connect the ring gear, the Planetenenträger- device and the sun gear rotationally effective. A drive unit, the auxiliary drive and the central gear are each rotationally connected to one of the three units ring gear, planet carrier device and sun gear. Preferably, the drive unit is rotationally connected to the sun gear, the auxiliary drive is rotatably connected to the ring gear, and the central wheel with the planet carrier device.

The rotary structure of a device according to the invention advantageously has at least one active element holder in which the at least one active element can be reversibly fastened.

In a device according to the invention, solar cells can be arranged on the active elements. Such a device according to the invention can be realized with or without accumulators for energy storage. For example, a paddle can supply the energy for self-rotation.

Another device according to the invention is realized with an accumulator (battery) in the paddle. The accumulator can be charged via an interface in the off state or disassembled with a charger or the battery is removable. The drive can be in the paddles or be realized in the housing. There may be communication between the paddles and external devices (eg for remote control or synchronization).

On the active elements light sources can be arranged. The light sources may be LEDs, for example. A lighting effect (eg pattern on the ceiling, casing, hull or lighting of the paddles) can be achieved by arranging the light sources on the housing or the rotating plate. A transparent or translucent paddle can be lit with integrated or external (for example, in the housing via light guide) light sources. A paddle may be used as a lamp when e.g. are arranged on the paddle surface light sources.

Several devices can be coupled to create a new device design. In this case, the devices preferably have a paddle angle of 0 ° (parallel rotating paddles), so that a common flow direction results. In this way, for example, can be generated in a space-saving manner devices with a large flow cross-section, for example, over an entire wall of a room.

The devices according to the invention can be designed for standing, lying or suspended operation. Thus, a device according to the invention can be designed as a desktop device, or be mounted on a wall or on the ceiling.

A device according to the invention can be realized combined with various other output options, for example light, music or fragrance delivery.

The appearance of the device can be changed by interchangeable paddles of various shapes, colors, housings, materials, etc. to personalize the device.

The energy is supplied via the network, via an external solar module or by means of integrated solar cells in the housing, which optionally still provided with a charging and accumulator unit, removable and thus can be recharged to the sun. Also possible is the power supply via a USB interface, or integrated or removable batteries or rechargeable batteries.

The device can be combined with a display for temperature, humidity, Internet News Feed, calendars, birthday calendars or other information.

If several devices are operated simultaneously in a room, the devices can be operated with a single remote control and / or electronically synchronized.

A drive device according to the invention for generating superimposed rotary movements of active elements comprises at least one drive unit, a support structure, a rotation structure rotatably mounted with respect to the support structure about a first rotation axis and rotationally connected to a drive unit; and one or more on the rotation structure about second rotation axes rotatably mounted supports for active elements, which are rotationally connected to a drive unit. A central wheel rotatably connected to the active element holders is arranged coaxially with the first axis of rotation, said central wheel being rotatable with respect to the support structure and the rotary structure about the first axis of rotation. Rotatable means in this sense that the central wheel and the rotary structure are not rotatably connected. However, depending on the configuration of the drive, there may be an indirect, rotationally effective coupling between the central wheel and the rotary structure.

The active element can be, for example, a rod and a paddle of a specific shape and effective area connected thereto for generating a directed air flow. The at least one active element can advantageously be operatively connected to the rotary structure and the support structure in such a way that the active element is in a first defined position during a rotation of the rotary structure about the first axis of rotation in a certain angular position, and in an angular position of the rotary structure rotated by 180 ° the active element to the first defined position, for example, is rotated by 90 ° about the second axis of rotation. The at least one active element to be rotated can therefore be operatively connected, for example, to the rotational structure and the support structure such that once the rotation structure rotates once around the first axis of rotation, the at least one active element rotates in the opposite direction about the second axis of rotation half a time. From the eye of the beholder, when the rotation structure rotates once around the first axis in a clockwise direction, the active element rotates by half a turn, also in the clockwise direction.

The central wheel and the rotary structure can be driven by a common drive unit, or by two different drive units.

The central wheel and the rotary structure may have different rotational speeds at the same rotational speed of the drive unit.

In an advantageous embodiment of a drive device according to the invention, two or more coupling units are provided with which the at least one drive unit can be rotationally connected to the central wheel and the rotary structure, wherein the two or more coupling units can be activated alternately.

In a particularly advantageous embodiment of such a drive device according to the invention, the two or more coupling units generate different speed ratios between central wheel and rotary structure and / or between central wheel and drive unit and / or between rotary structure and drive unit.

In another particularly advantageous embodiment of such a drive device according to the invention, two coupling units are provided, between which it is possible to switch back and forth by changing the direction of rotation of the drive unit. Particularly advantageously, the coupling units are configured such that the directions of rotation of the central wheel and the rotary structure are independent of the direction of rotation of the drive unit.

A further advantageous Ausführunsgform such inventive drive device comprises an auxiliary drive and an addition gear with a sun gear, a ring gear, and a rotatably disposed between the ring gear and the sun gear planet carrier device. On the planet carrier device planetary gears are rotatably arranged, which the ring gear, the planetary gear carrier device and the sun gear rotatably connect. A drive unit, the auxiliary drive and the central gear are each rotationally connected to one of the three units ring gear, planet carrier device and sun gear.

In a particularly advantageous variant, the drive unit is rotationally connected to the sun gear, the auxiliary drive to the ring gear, and the central wheel to the planet carrier device.

An inventive drive device, for example, for a turbomachine according to the Swiss patent applications no. 021 38/1 0 and N r. 001 94/1 1 of the Applicant. The generated, superimposed rotational movement of the rotary structure and the paddle-effect elements causes a gentle, directed and adjustable flow in a particular medium, such as air.

If the ratio of the two superimposed rotational movements is set such that once the axis of rotation rotates about the first axis, the axis of the at least one active element rotates halfway in the opposite direction about the second axis, then an air flow is generated which is continuous in one direction flows. If the ratio of the two rotational movements does not correspond to this characteristic, the air flow can be directed in more than one direction.

The fields of application of a device according to the invention for generating overlapping rotational movements are not limited to the generation of air flows. The device can also be used, for example, in water or other media. It is also suitable by reversing the function as an electric current generator in various flow media such as air and water, the kinetic energy of a fluid is captured on the active elements and transmitted via the superimposed rotary motion to a coupled-current generator. Further fields of application are, for example, the mixing of media or the three-dimensional movement of objects.

Embodiment of the invention

The examples given below are given for a better illustration of the present invention, but are not intended to limit the invention to the features disclosed herein.

The superimposed rotational movements of paddle and rotary plate of a device according to the invention is shown schematically in FIG. Shown is a ventilation device according to the invention with only one paddle 61, whose orientation is symbolized by the black arrow. A rotationally mounted rotary plate (not shown) of the device is rotated about a rotation axis 10. On the rotary plate, the paddle is rotatably mounted on a further axis 9, wherein this second axis of rotation does not coincide with the first axis of rotation. A rotational movement of the paddle 61 is coupled to the rotational movement of the rotary plate in a ratio of 2: 1. That is, the paddle 61 makes a complete U mdrehung about its own axis 9, while the rotary plate 5 makes two full revolutions around its own axis 1 0. This is illustrated in eight steps each with a 90 ° turn of the rotary plate.

As a result of the coupled rotation of the rotary plate and paddle, the paddle is aligned parallel to the y axis, α = 0 °, and in the maximum effective power position when the rotational angle β of the axis 9 about the axis 1 0 of the rotary plate is 0 ° (Step 1 and 5), and parallel to the x-axis (a = 90 °) at a rotation angle of β = 1 80 ° (steps 3 and 7). In the intermediate angles, the paddle is tilted accordingly. As a result, the paddle in position 1 and 5 pushes the air to the left in the direction of the x-axis, while in position 3 and 7, the paddle moves to the right, without oppose the air a significant resistance. The result is an effective air flow 1 00, which runs in a certain direction, here in the direction of the x-axis. The direction of the effective air flow 1 00 is given by the direction of action 1 01 of the device, which is defined by the normal of the effective area of the paddle at that angular position at which the active surface moves vertically through the fluid. In this figure, this is the angular position α = 0 °, β = 0 ° A schematic representation of the direction of the resulting air flow 1 00 is shown in Figure 2. For an inventive device with a paddle 61, the position and orientation of the paddle at α = 0 °, 90 °, 1 80 ° and 270 ° and the direction of rotation of the rotary plate 5 and the counter-rotating paddle 61 is shown schematically. The wind direction 100 and its strength is directed and is perpendicular to the surface of the paddle at the rotational position in which the paddle is perpendicular to the direction of movement of the paddle, the effective direction 01, and the paddle moves in each case with full attack surface in the air. In Figure 2, this is the position (I).

By changing the orientation of the paddle with respect to the axis of rotation, the flow direction of the device according to the invention can be changed very easily.

FIG. 3 shows a side view of a possible embodiment of a drive device 66 according to the invention for a ventilation device according to the invention with two active elements in the form of two paddles (not shown), in which the movement of the paddles takes place via a planetary gear. On a supporting structure 1 designed as a base plate, a central axis 1 1 is freely rotatably mounted, which defines the central axis of rotation 1 0. With the central axis 1 1, in turn, a support structure for the paddles in the form of a rotating structure 5 designed as a rotary plate is connected. On opposite sides of the rotary plate fastening devices 7, 7 'for the paddle are rotatably mounted. These paddle holders 7, 7 'can receive and lock the rods 62, 62' of the paddles in a manner secure against rotation, wherein the connection between the paddle holder and the paddle can be proprietary. A drive motor 3 rotates via a drive axle 3a a drive pinion 1 9. With the central axis 1 1 fixedly connected to a drive wheel 6, which reduces the rotation of the drive pinion to the desired speed of the central axis 1 1. Two intermediate wheels 24, 24 'are rotatably mounted on the rotary plate. A central gear 25 is coaxial with the central axis 1 1 and arranged substantially immovable to the base plate 1 and operatively connected to the intermediate wheels. As a result of the rotation of the rotary plate, the fixed central wheel 25 rotates the intermediate wheels 24, 24 ', and thus the gears 8, 8' of the fastening devices 7, 7 'coupled to the intermediate wheels, for the paddles. The result is a rotational movement of the paddle or active elements about the central axis of rotation 1 0, and at the same time an opposite rotational movement about the axes of rotation 9, 9 'of the paddle. The gear ratios of the gears 25, 24, 24 ', 8, 8' are chosen such that a translation of 2: 1 results, so that the paddle during rotation of the rotary plate 5 half a time around its own axis 9, 9 'rotate ,

The bearing active elements thus rotate with the rotary plate 5 in a circle about the axis 1 0. By the gear coupling of the drive wheels 8, 8 'of the active elements on the intermediate wheels 24, 24' with the fixed central wheel 25, the drive wheels 8, 8 'in offset an opposite rotation for rotary plate rotation. If the drive wheels 8, 8 'have twice as many teeth as the central wheel 25, then this results in a transmission ratio of 2: 1, resp. 1: 2, resp. - 1: 2. In the example shown, the axes of rotation 9, 9 'are tilted outwards relative to the central axis of rotation 10. This has no major influence on the effect of the ventilation device according to the invention, since the effective effective area of the active element / paddle in the radial orientation (compare positions 1, 5 in FIG. 1) remains unchanged as long as all axes of rotation intersect.

It is even possible that the rotation axes 9, 9 'are perpendicular to the axis of rotation 1 0 of the rotary plate. However, the efficiency of the device is greatest when all axes of rotation 9, 9 ', 10 are parallel, since in such a case, in the intermediate positions (compare positions 2, 4, 6, 8 in Figure 1) the air flow is perpendicular to the axis 1 0 stands, while at a tilt of the axes of rotation 9, 9 'of this air flow, a vector component is directed upwards and downwards and picks up.

The drive device 66 is advantageously arranged within a cover housing, which, however, is not shown here for the sake of clarity.

Instead of using a planetary gear, a drive device can also be realized with a V-belt, which runs around the fixed central gear and the paddle gear, whereby the intermediate gear can be dispensed with.

In a basic embodiment of the invention, the effective direction of the device, that is to say the direction of the generated air flow, is fixed in relation to the housing. To change the effective direction, the whole device can be turned. However, an adjustment of the direction of action can also be achieved by rotating the central wheel 25 with respect to the support structure. If the central wheel 25 is rotated with respect to the supporting structure 1, this has the same effect as if the whole apparatus were rotated.

The generated wind direction, which results from the effective direction, can be configured by the user in the off state and / or set in operation over 360 °.

In the variant of a ventilation device according to the invention shown in FIG. 3, a housing (not shown) is rotatably supported on the support structure 1. The central wheel 25 is rotatably mounted on the central axis 1 1, but at the same time is coupled to the housing via a connecting element (direction sensor) 21. The housing has such a high static friction against the supporting structure that during normal operation the central wheel is without external action rotationally blocked relative to the support structure and thus locked substantially fixed.

The adjustment of the central wheel can be done by hand. In the illustrated drive device, the rotatably mounted housing is rotated by hand. Thus, the central wheel 25 is rotated by the desired angle. The turntable does not rotate with it, but the active elements. Due to the coupling of the central wheel 25 via the intermediate wheels 24, 24 'with the drive wheels 8, 8' latter are also drehverstellt, according to the adjustment of the central wheel 25. Since the drive wheels 8, 8 'mechanically with the active element holders 7, 7' and these are connected to the paddle rods 62, 62 ', the paddles are thus also rotated accordingly, which is an adjustment of the effective direction equivalent. Subsequently, the central wheel is locked again, and the drive can be put back into operation.

It is also possible to turn the fixed central gear by means of an additional actuator. In this way, the direction of action can also be changed during operation, so that, for example, an automatic pivoting function for the air flow can be realized.

A possible embodiment of a ventilation device 60 according to the invention is shown in FIG. In this device, two paddles 61, 61 'are inserted in corresponding holding devices 7, 7' in the rotary plate 5.

In the illustrated example, further, unused holder devices are present, which allows a symmetrical configuration of the device with optionally between one and four paddles.

In the off state, the device can be configured by the user. For example, paddles can be replaced.

An apparatus according to the invention can be realized in various variants. The devices may be equipped with one or more paddles and the devices may be functionally coupled to new designs or only strung together (ie with or without functional coupling).

For example, FIG. 5 (a) shows a ventilation device according to the invention, in which two paddles 61, 61 'are arranged between two housings 58, 58'. A first paddle 61 (hatched marked) is in the maximum operative position, while a second paddle 61 'is perpendicular to the viewing direction (minimum operative position). Both housings have a rotary plate in which the paddles are rotatably mounted. The drive device is arranged in one or both housings.

Such a construction allows a very space-saving and compact design. For example, very small ventilation devices can be realized, which can be placed in a workplace in confined spaces. Use as a standing fan is also advantageous.

FIG. 5 (b) shows an embodiment of a device according to the invention, in which a rotary plate with two paddles is arranged on each side of a housing 58. Turn the paddles to the left and right.

Similar variants are shown in Figures 5 (c), (d), in which two such devices are arranged linearly stacked. The upper and lower paddles of the device 60 may rotate in the same direction as shown in Fig. 5 (c) or in the opposite direction of rotation but in the same effective direction as in Fig. 5 (d). The two paddle sets can also be operated completely independently of one another, for example with different effective directions or power levels. In FIG. 5 (e), two devices, each with a paddle, are arranged next to one another. Thus, designs with synchronously rotating paddles or a device with multiple effective directions can be realized.

Four further variants 60 of a device according to the invention are shown in FIG. Figure 6 (a) shows an embodiment with light sources 90, 90 '(e.g., LEDs) integrated in the housing 58 or turntable 5 which illuminate the paddles. FIG. 6 (b) shows a paddle 61 made of transparent or translucent material, wherein light sources 90 are integrated in the paddle 61 and fastened to the paddle rod 62. FIG. 6 (c) again shows a paddle 61 in which the light sources 90 are mounted on the surface of the paddle 61. Such a paddle thus also serves as a light source.

In a device according to FIGS. 6 (b) and 6 (c), the light sources 90 receive the electrical energy via the paddle rod 62. This can be designed such that it consists of electrically conductive material and at the same time serves as an electrical connection. The opposite pole may be an inner or outer conductor shielded from the paddle bar material. The feeding takes place from the housing 58 via an electrical contact in the paddle holder 7.

Another possibility for feeding the light sources are integrated solar cells in the paddle, which are optionally equipped with a stabilization circuit, which can also serve as a control or communication interface, and optionally with an accumulator. Another technical solution for the power supply is a removable battery or rechargeable via an electrical connection rechargeable battery. Another technical solution for the power supply is an integrated accumulator, where the whole paddle can be connected to a charging station for charging.

FIG. 6 (d) shows yet another advantageous embodiment in which light from a light source 90 integrated in the housing 58 is transported via optical fibers 91, 91 'to and through the light-conducting paddle rods 93, 93' and in the paddle 61, 61 'is emitted.

The described embodiments in FIG. 6 may include various technical solutions for diminishing, color mixing, turning on / off, or generating color effects or chases.

FIG. 7 shows another advantageous embodiment of a ventilation device according to the invention, in which a direct drive motor 63, 63 'is integrated in the lower end of the paddle rod 62, 62'. The arrangement, function and movement of rotary plate 5, paddle wheels 8, 8 ', intermediate wheels 24, 24' and fixed central wheel 25 are designed analogously to the description of Figure 3. The paddle rod 62, 62 'is non-rotatably connected to the paddle holder 7, 7' and the paddle wheel 8, 8 'and connected directly or via a paddle gear with the rotor of the direct drive motor 63, 63'. The locking part 7a, 7a 'is rotatably connected to the rotary plate 5 and the stator of the direct drive motor 63, 63'. The direct drive motor rotates the paddle about its axis. At the same time, the direct drive motor drives the paddle wheel 8, 8 'directly or via an additional gear via its drive axle. The rotation of the paddle wheel via the coupling with the intermediate gear 24, 24 'and the fixed central wheel 25 to the desired rotational movement of the rotary plate 5 in opposite directions to the rotation of the paddle 61 according to the description of Figure 3.

FIG. 8 shows a still further embodiment of a ventilating device according to the invention, having a fixed internal toothed ring gear 25a connected to the housing (not shown) or the supporting structure, instead of intermediate wheels and a fixed central wheel. The paddle rod 62, 62 'is secured against rotation with the paddle holder 7, 7' and the paddle wheel 8, 8 'and connected directly or via a gear to the rotor of the direct drive motor 63, 63'. The locking part 7a, 7a 'is connected against rotation with the rotary plate 5 and the stator of the direct drive motor. The direct drive motor 63, 63 'drives the paddle wheel 8, 8' via its drive axle directly or via a paddlewheel gear, and simultaneously rotates the paddle about its axis. The rolling of the paddle wheels 8, 8 'on the internally toothed hollow wheel 25 causes the rotation of the rotary plate 5 in the opposite direction of rotation for rotation of the paddle wheels 8, 8'. The toothing of the ring gear 25a in relation to the paddle wheel 8, 8 'and the shape of the toothing are chosen so that a translation of z. B. 2: 1 results so that the paddle 61 during a rotation of the rotating plate 5 rotate twice about its own axis 9, which in turn corresponds to the movement according to the description of a device of Figure 3.

Figure 9 shows a similar embodiment as Figure 8, but with additional gears for individual conversion of the speed of the direct drive motor 63, 63 'on the paddle 8, 8' and on the paddle bar 62, 62 '. The paddle rod 62, 62 'is not directly connected to paddle holder 7, 7' and paddle wheel 8, 8 '. The paddle wheel gear 7b, 7b 'generates the conversion of the rotational speed of the di rect drive motor 63, 63' to the desired speed of the paddle wheel 8, 8 '. The paddle gear 65, 65 'generates the Umsetzung of the speed of the direct drive motor 63, 63' to the desired speed of the paddle. The ratio of the ratios of the two gears should be chosen so that the desired speeds and directions of rotation of the paddle and the rotary plate 5 result. The advantage of this embodiment over an embodiment according to Figure 8 is that an identical toothing for the paddle wheels 8, 8 'and the internally toothed ring gear 25a can be selected. The feeding of the direct drive motor 63, 63 'can take place via a removable battery or via a rechargeable battery via electrical contact. Alternatively or additionally, solar cells integrated in the paddle can convert light into electrical energy and feed the direct drive motor directly, or the generated electrical energy can be temporarily stored in the named accumulator. FIG. 10 (b) shows such an embodiment of a paddle 61, wherein the direct drive 63 is integrated directly into the paddle rod, an electrical circuit 75 for the optimum charging of the accumulators 76, and for driving the direct drive motor and optionally for the internal and external communication is used. FIG. 10 (a) shows how two such paddles 61, 61 'are assembled to form a device according to the invention. Alternatively, the elements can Active element gearbox, additional gearbox, direct drive motor, accumulator and electrical circuit can be arranged either in the paddle holder 7, 7 'or in the paddle rod 62, 62'.

A further embodiment of a device according to the invention is given in the combination of embodiments according to FIG. 10 (b) and FIG. The solar power supply or battery power supply in the pad 5 del is used to replace or supplement the power supply of the drive via an external power source or a built-in battery or accumulator housing. The energy is thereby connected via electrical contacts (eg sliding contacts or ball contacts) on the paddle holder or on the paddle wheel directly to the power supply of the drive motor. Alternatively, the energy can also be stored in an accumulator integrated in the housing.

Various embodiments of drive devices according to the invention are discussed below, which can be used particularly advantageously for ventilation devices according to the invention. However, they can generally be used to generate superposed rotations.

The inventive drive devices have compared to the previously discussed Ani s drive devices with a fixed central and intermediate wheels has the advantage that changing the gear ratio during operation is easier to solve and that the central wheel does not have to be firmly connected to the basic device, which in the technical embodiment of Ventilation device allows more flexibility.

Figure 1 1 shows an advantageous embodiment of an inventive drive device 20 example of a ventilation device with two paddles (active elements) 61, 61 ', in which the transmission of rotational movement from the drive 3 to the active elements separated from the drive of the rotary plate 5, on which the active elements are rotatably mounted.

The drive 3, advantageously an electric motor, is firmly connected to the support structure 1. On the drive axle 3a a double drive pinion 1 5 is attached. The rotary plate drive axle 1 1 is fixed

25 is connected to the rotary plate 5 and is mounted on a bearing 1 2 rotatably mounted in the support structure. 1

The drive 3 drives on its own axis 3a and the double drive pinion 1 5 at. This transmits the torque on the lower row of teeth 1 5a on the mounted on the rotary plate drive shaft 1 1 rotary plate drive wheel 6, so that the rotary plate 5 rotates with the speed resulting from the ratios of the gears 6, 1 5a.

30 Übbe the drive wheel 6 is a double central wheel 1 3, that is freely rotatably mounted on the rotary plate drive axle 1 1. The upper gear 1 5b of the drive pinion 1 5 drives the lower gear 1 3a of the double central wheel 1 3, which in turn via the upper gear 1 3b, the two with the active elements 61, 61 'rotatably connected active element drive wheels 8, 8' drives. The rotatably mounted on the rotary plate 5 active elements 61, 61 ', z. B. paddles (not shown),

35 rotate in accordance with the by the gear ratio of the gears 1 5b, 1 3a, 1 3b, 8, 8 ' predetermined speed around its own axis of rotation 9, 9 '. At the same time they rotate about the central axis of rotation 1 0 due to the rotation of the rotary plate.

In order to generate a superimposed rotary motion with a rotary plate rotation and a simultaneous rotation of the active elements, the ratio of the gears and the number of teeth in the construction must be defined accordingly. The double drive pinion 1 5, the rotary plate drive wheel 6, the double central wheel 1 3 and the drive wheels 8, 8 'of the active elements must be designed so that the drive wheels 8, 8' make in the time, for example, a half turn, in the the turntable drive wheel 6 makes a complete revolution. From the viewer's point of view, this involves two rotations in the same direction of rotation. Considering only the axes of rotation 9, 9 'of the active elements and the axis of rotation 1 0 of the rotary plate, so the drive wheels 8, 8' half turn in the opposite direction to a U m rotation of the rotary plate due to the rotation of the mounted in the rotary plate active elements 5 do.

At a ratio between double central wheel 1 3 and the drive wheels 8, 8 'of, for example, 3: 1, the double central wheel 1 3 during one revolution of the rotary plate 5 make a sixth U mdrehung so that the drive wheels 8, 8' make a half U mdrehung , It follows that the two-fold central wheel 1 3 must rotate for a constant effective direction one-sixth faster than the turntable drive wheel 6. At a ratio between dual central wheel 1 3 and the drive wheels 8, 8 ', for example, 2: 1, the dual central wheel 1 3 for the constant direction of action turn a quarter faster than the Drehplatten- drive wheel. 6

The use of a freely rotatable central wheel allows a more compact design, since, for example, in comparison to Figure 3 is dispensed with additional mounted on the rotary plate intermediate wheels. Figure 1 2 shows a further advantageous embodiment of a drive device according to the invention, with a built-in rotary plate 5 direct drive 2. This direct drive, such as a brushless DC motor rotates the rotary plate 5 by the stator of the motor is firmly connected to the support structure 1, during the Rotor is directly connected to the rotary plate 5. The transmission of the rotary motion from the direct drive 2 on the brackets 7, 7 'for the active elements (not shown) via a fixed gear with a rotatably mounted double-gear ratio 1 8. The driven by the direct drive 2 rotary plate drive wheel 6 drives via a freely rotatably mounted translation gear 1 8 with two sprockets 1 8a, 1 8b an additional central wheel drive wheel 1 7 at. a central wheel axis 4 connected to the central wheel drive wheel 1 7 is freely rotatably mounted in the interior of a hollow axle 1 6, which in turn is fixedly connected to the rotary plate 5 and at the same time is rotatably mounted in the support structure 1. The Zentralrad- axis 4 transmits the rotation on the mounted thereon simple central wheel 1 4, which is arranged on the outer side of the rotary plate 5. This central wheel 1 4 finally moves the drive wheels 8, 8 'of the active elements or their brackets 7, 7'. A variant of a device analogous to Figure 1 2 is shown in Figure 1 3. A brushless DC motor 1 1 0 drives the rotary structure, the coils of the stator of the motor are placed directly on the electronic circuit board 1 1 1, the rotor of the motor consists of a ring magnet and is connected to a motor pinion 1 1 2, that transmits the rotation to an additional ratio gear 1 1 3, which in turn is operatively connected to the double ratio gear 1 8. The result is a 1: 6 or 1: 9 translation of the motor axis on the turntable.

Figure 1 4 shows an embodiment of a drive device according to the invention, in which the transmission ratio can be switched.

The drive (not shown) drives via a drive pinion 1 9 and a reduction gear 20, the rotary plate -Antriebsrad 6 and thus the rotary plate 5, on which active element holders 7, 7 'are rotatably mounted. A central wheel drive gear 1 7 is connected via a rotatably mounted within the Drehplattenantriebsachse shaft 4 with a arranged on the outside of the rotary plate 5 simple central wheel 1 4. The simple central wheel 1 4 moves on the drive wheels 8, 8 ', the active elements.

With the rotary plate drive shaft 1 1, which is fixedly connected to the rotary plate 5, a second rotary plate drive wheel 6 'is still connected so that the rotary plate rotation is also available at the lower part of the housing.

The transmission of the rotation from the second rotary plate drive wheel 6 'to the central wheel drive wheel 1 7 via a double-translation gear 1 8, 1 8'. Two different double-ratio gears 1 8, 1 8 'are arranged on a displaceably arranged switching lever. With the operation of the U mschalt lever 21, either the first 1 8 or the second 1 8 'double-ratio gear with the two gears 6, 1 7 are coupled so that two different ratios between rotary plate drive wheel 6 and simple central 1 4 can be realized.

Figure 1 5 shows a further advantageous variant of an inventive drive device, in which a change of the transmission ratio can be achieved only by changing the direction of rotation of the drive motor 3. A switching unit 22 is rotatably mounted on the shaft 3 a of the drive 3 is arranged. The central gear 22 a of the U mschalteinheit 22 is fixedly connected to the shaft 3 a of the drive 3. Rotates the drive shaft 3a in a clockwise direction, this causes a pivoting of the switching unit 22 also in U clockwise, so that the left gear pair 22b both with the rotary plate drive wheel 6 and with the lower ring gear 1 3a a freely rotatably mounted dual central wheel. 1 3 couples. The result is a specific ratio between the double central wheel 1 3 and the rotary plate drive wheel 6, and the rotary plate 5 and the active with the upper ring gear 1 3b active element drive wheels 8, 8 '

If the drive shaft rotates counterclockwise, this also causes the switching unit 22 to pivot in a counterclockwise direction, so that with the right-hand gear pair 22c with the gear teeth coupled to the 6 and 1 3a, and a certain gear ratio between the dual central wheel 1 3 and the rotary plate drive wheel 6 is made. The interposed in this constellation gear 22d is used to correct the direction of rotation, so that the two-fold central wheel 1 3 and the Drehplatten -Antriebsrad 6 rotate in both directions of rotation of the drive shaft 3a always in the same direction and only the gear ratio changes.

1 6 shows an advantageous embodiment of a drive device according to the invention with two output units 3, 3 'for the individual drive of rotary plate 5 and central wheel 1 3. The embodiment differs from the embodiment according to FIG. 11 in that two drives 3, 3' each with a single drive pinion 1 9, 1 9 'are used. The first drive 3 drives via the single pinion 1 9, the rotary plate drive wheel 6, which is connected via a rotatably mounted in the support structure 1 axis 1 1 with the rotary plate 5. A double central wheel 1 3 is rotatably mounted on the rotary plate drive shaft 1 1. The second drive 3 'drives via the single pinion 1 9', the lower gear 1 3a of the central wheel 1 3, which drives the drive wheels 8, 8 'of the active elements via the upper gear 1 3b. The rotary plate drive wheel 6 and the double central wheel 1 3 can be controlled individually. The adjustment and regulation of the speed ratio of the two gears 8, 8 'and the rotary plate by means of electronics and / or software, for example, based on the position detection of the drives 3, 3' or that of other rotatably mounted elements.

Figure 1 7 shows an embodiment of an inventive device with two direct drive units 2, 2 'for the individual drive of rotary plate 5 and simple central wheel 1 4. In this embodiment, translation gears omitted completely. A first direct drive 2, for example, a brushless DC motor, is disposed between the support structure 1 and the rotation plate 5 so that the stator is connected to the support structure and the rotor is connected to the rotation plate. In a second direct drive 2 ', the stator with the support structure 1 and the rotor via a Zentralradachse 4 with the above the rotary plate 5 arranged simple central wheel 1 4 is connected, which rotates the drive wheels 8, 8' of the active elements. The rotary plate 5 and the simple central wheel 1 4 can be controlled individually with the separate direct drives 2, 2 '. The adjustment and regulation of the speed ratio of rotary plate 5 to simple central wheel 1 4 by means of electronics and / or software and, for example, the position detection of the drives 2, 2 'or other rotating parts.

Figure 1 8 shows an embodiment of a drive device according to the invention, in which the gear ratio can be switched. The drive 3 drives via the drive pinion 1 9 the simple central wheel 1 4, which in turn drives the two active element drive wheels 8, 8 '. The drive 3 simultaneously drives the vertical double-translation gear 26. This is rotationally fixed, but vertically displaceable, arranged on the axis of the drive pinion, and has an upper gear 26a and a lower gear 26b. With the operation of a reversing device (not shown) Either the upper gear 26a or the lower gear 26b of the vertical double-translation gear 26 can be respectively coupled to the upper row of teeth 6a or lower row 6b of the rotary plate drive wheel 6, so that two different ratios between the rotary plate drive wheel 6 and Simple central wheel 1 4 can be realized. Figure 1 9 shows an embodiment of another advantageous inventive drive device, with an addition gear 29 for superposition of an additional rotational movement. The drive 3 drives via its drive axle 3a and a firmly coupled thereto, simple drive pinion 1 9 the simple central wheel 1 4, which in turn drives both active element drive wheels 8, 8 '. The drive 3 also drives via a second addition gear 29, a second, simple drive pinion 1 9 ', which is freely rotatably mounted on the axle 3a. The second simple drive pinion 1 9 'transmits the torque to the rotary plate drive shaft 6 mounted on the rotary plate drive wheel 6 so that the rotary plate 5 rotates with the speed resulting from the gear ratios of the addition mode 29 and the gears 1 9' and 6.

The addition gearbox 29 (see Fig. 1 (b)) is designed so that a sun gear 30 of the addition gear is fixedly connected to the rotating part of the drive 3 and the first simple drive pinion 1 9, which simultaneously the rotational movement of the simple central wheel 1 4 determines, and thus the active element drive wheels 8, 8 '. A planet carrier device (not shown for clarity) is fixedly connected to the rotatably mounted on the drive axle 3a, the second simple drive pinion 1 9 '. On the outside of the addition gear 29, a ring gear 30 is rotatably mounted, which is connected via a belt 28 with an auxiliary drive 27. On the planetary carrier device two planetary gears 32 are arranged, which cooperate with both the sun gear 30 and the ring gear 33. When the ring gear 33 of the addition gear is stationary, the drive 3 rotates via the sun gear 30 and the planet wheels 32, the Planetenträger- device, and via the gear 1 9 ', the rotary plate drive wheel. 6

The gear ratio of central wheel rotation and rotary plate rotation is determined on the one hand on the transmission ratio of sun gear 30, planet gears 33, ring gear 33, second simple drive pinion 1 9 'and Drehplattenantriebsrad 6, and on the other hand on the ratio of the first simple drive pinion 1 9 and the simple Central wheel 1 4 determined. The addition gear 29 and the mentioned ratios can be chosen so that a certain advantageous ratio exists.

With the auxiliary drive 27, the ring gear 33 of the addition gear 29 can be rotated via a belt 28, which slows down or accelerates the rotational speed of the planet gears 32, and thus at a given rotational speed of the sun gear 30 and the rotational speed of the planet carrier device and the rotary plate drive. With the auxiliary drive 27 and the addition gear 29 thus the rotational speed difference between rotary plate rotation and central wheel rotation can be flexibly adjusted during operation. In the embodiments discussed above, the axes of rotation 9, 9 'of the active elements and the axis of rotation 1 0 of the rotary plate were tilted. The axles may in principle have a wide variety of angles (0-180 °) between the axis of rotation 110 of the rotary plate and the axes of rotation 9, 9 'of the active elements 61, 61'. The axis distance can be very small to very large and one or more active elements or active element holders can be provided.

The specific embodiments disclosed are not intended to limit the scope of the present invention. Various modifications and modifications will become apparent to those skilled in the art from the foregoing description and the drawings, in addition to the disclosed examples which are also intended to be within the scope of the claims.
