The valve member is movable between a closed position in which it rests on the valve seat, and an open position in which it is lifted from the valve seat, wherein in the open position, a first, diffused air flow between the main body and the valve member can flow out of the opening ,

STATE OF THE ART

From the FR 29 12 960 A1 a ventilation device is known in which a base body having an opening and a valve having a valve seat along the circumference of the opening and a valve member which is convertible between a closed position and an open position, are provided.

The venting device disclosed therein is suitable for allowing diffuse aeration to escape through a gap between the valve seat and the valve member in the open position when the valve member is lifted from the valve seat. Alternatively, when the valve member rests on the valve seat, flow through one portion of the valve member is possible to access a different space area with respect to the venting device.

When in the FR 29 12 960 A1 Ventilation device disclosed it is possible to switch between two different air streams, with a first air flow diffused and a second air flow is directed.

However, the ventilation device described in this document is not suitable for discharging both a diffused and a directed air flow and therefore has drawbacks with respect to its adaptability to the individual needs of a vehicle occupant.

PRESENTATION OF THE INVENTION

The object of the present invention is to provide a ventilation device of the above technical field, which has a particularly good adaptability to the individual needs of a vehicle occupant. The task is more general in the FR 29 12 960 A1 described construction to the effect that the producible by the ventilation device air flow can be controlled flexibly in a structurally simple manner. In particular, the object is to provide a ventilation device that can output both a first, diffused air flow and a second, directed air flow.

The object of the invention is achieved by the subject matter of claim 1.

According to the invention, a ventilation device for a vehicle is provided which comprises a main body with an opening and a first valve with a valve seat along the circumference of the opening and a valve member. The valve member is movable between a closed position in which it rests on the valve seat, and an open position in which it is lifted from the valve seat, wherein in the open position, a first, diffused air flow between the main body and the valve member can flow out of the opening , The ventilation device further comprises a discharge nozzle, which is designed to generate a second, directed air flow out of the ventilation device, wherein the discharge nozzle is mounted on the valve member. The ventilation device is characterized in that the exhaust nozzle is mounted on the valve member such that the generation of the second, directed air flow is independent of the generation of the first, diffused air flow controllable.

By means of the ventilation device according to the invention, individual needs of a vehicle occupant and / or driver of a vehicle can be fulfilled to a greater extent than was hitherto possible. In particular, it is now possible to produce both a diffused aeration and a directed airflow through a single aeration device. In this way, a draft-free ventilation of the vehicle interior through the diffuse air flow and independently, in particular simultaneously, a directed air flow can be provided, which is perceived by a vehicle occupant particularly intense. Due to the ventilation device according to the invention no additional space in the vehicle is required by the integral design and opens up new design options.

The exhaust nozzle according to the invention is rotatably mounted in the valve member as a ball joint and preferably substantially spherical. The feature according to which the exhaust nozzle is substantially spherical, means that its outer contour is to have the shape of a ball or a partial sphere in the majority. The exhaust nozzle in this case has openings for the inflow and outflow of an air flow, but has substantially spherical shape with respect to its outer contour.

In this way, the exhaust nozzle can be particularly well aligned in the valve member, so that the second, directed air flow is largely adjustable in its orientation. The orientation of the second, directed air flow is independent of the position of the valve member or the design of the diffused air flow.

According to the invention, in the aeration device described above, the discharge nozzle can be rotated by a defined angle in such a way that the second, directed air flow can be shut off by rotation of the discharge nozzle by preferably at least this angle. This is an elegant and efficient way to control the second, directed air flow, which can be so far completely independent of the first, diffused air flow aligned and unlocked or unlocked.

Preferably, the exhaust nozzle is designed as a second valve. This means that the discharge nozzle preferably acts like a valve, that is, it can release or interrupt the air flow. This allows the directional airflow to be switched on and off independently of the diffused airflow, depending on the wishes of the vehicle occupant.

In a preferred embodiment, the exhaust nozzle comprises a hollow cylinder, which is designed in particular integrally with the exhaust nozzle. The hollow cylinder inside the exhaust nozzle provides for efficient and accurate alignment of airflow through the exhaust nozzle and thus allows the directional airflow to be particularly well adjusted for its alignment precision.

In a preferred embodiment, the discharge nozzle is rotatable by an angle, starting from the integrated hollow cylinder, of about ± 90 ° such that the shell or side surface of the essentially spherical discharge nozzle, which is not perforated by the formation of the hollow cylinder, rests against the surface and thus the Air duct of the exhaust nozzle is completely prevented. Furthermore, a latching mechanism is provided for this purpose, which indicates the latching of the exhaust nozzle in the closed position in a haptic or acoustic manner and ensures against over-rotation of the spherical joint.

In a further preferred embodiment, the first valve is continuously adjustable between the closed position and the open position, so that the flow of the first air stream is infinitely adjustable. A mere switching between an open and closed position only allows the connection or disconnection of a diffuse air flow. On the other hand, according to the preferred embodiment, a possibility is provided for continuously controlling the intensity of the air flow, that is to say its flow, and thus adjusting the ventilation intensity through the diffuse air flow.

Advantageously, the ventilation device further comprises a supply line for supplying an air flow for outflow from the ventilation device, wherein the supply line and / or the first valve has an air guide element in order to direct the first, diffuse air flow into a preferably turbulent spiral flow.

A diffused air flow is characterized according to this invention in particular by the fact that the flow of the air flow diverges and is particularly turbulent. In contrast, a directed air flow has a substantially laminar and parallel flow. In the diffuse air flow, a draft-free ventilation of the vehicle interior is made possible, whereas the intensity of a directed air flow due to its laminar flow is perceived more intensively by the vehicle occupant.

By the preferred provision of an air guide element in order to direct the first, diffuse air flow into a preferably turbulent spiral flow, the diffuse expression of the first air flow becomes particularly strong and therefore enables a particularly efficient generation of a diffuse air flow.

Preferably, the ventilation device further comprises a second exhaust nozzle for generating a third air flow out of the ventilation device, which is mounted on the first valve and preferably at least partially surrounds the first exhaust nozzle. The third air flow of this preferred embodiment is also advantageously a directed air flow, which, for example, has only one orientation and is not adjustable. In addition, however, it is also possible to carry out the third air flow as an adjustable air flow. According to this preferred embodiment, it becomes possible to meet even more various individual needs of a vehicle occupant by having a particularly wide variety of possible ventilation modes to choose from.

The feature according to which the second outflow nozzle for generating the third airflow preferably at least partially surrounds the first outflow nozzle has, inter alia, the advantage that in this way a particularly simple way of opening or closing the second outflow nozzle results. In this way, for example, a closure device can be provided, which is rotatable about the first discharge nozzle and can be particularly easily fixed to the latter. Besides, the preferred embodiment requires very little space and allows great design freedom.

Advantageously, the first valve and the first exhaust nozzle and preferably the second exhaust nozzle are independently openable and closable. In this way, a particularly large variety of achievable individual wishes of a vehicle occupant can be achieved, which thus can both the diffuse and the directed air flow independently of the other air flow on and off and set.

A preferred embodiment of the ventilation device further comprises a lighting means, which is arranged so that an air flow releasing area of the ventilation device can be illuminated. In this way it is on the one hand possible to achieve particularly appealing lighting effects in a vehicle. On the other hand, it is possible to provide an optical feedback on the status of the valve or the entire ventilation device.

Preferably, the first, diffused airflow with respect to an orientation of the supply line for directing an airflow out of the aeration device flows in an angular range from the aeration device that is between 15 degrees and 75 degrees. Such an angled air flow, which forms a diffuse air flow, leads to a particularly spacious and thus efficient ventilation of a vehicle interior, without conveying the feeling of a draft. In principle, it is possible that the diffused air flow occupies every angle with respect to the orientation of the supply line. However, said preferred angular range leads to a particularly high efficiency of ventilation.

The preferred stepless adjustability of the first valve between the closed position and the open position can be realized for example by a thread. In addition to this preferred realization of the stepless adjustability, a preferably infinitely variable adjustment of the valve can also be carried out by a magnetic mechanism, a slide guide, a pusher or a telescopic movement. It can also be provided by removing a fuse the valve for cleaning purposes, such as the introduction of the component in a bucket or the like to remove from the valve seat. For example, such a lock on the thread could be solved to completely unscrew the valve.

The ventilation device according to the invention can be integrated particularly well in a surface of a vehicle. A surface-integrated design of the ventilation device is particularly preferred because it is visually appealing and safety-friendly.

The ventilation device can preferably be produced by in-mold methods, in particular multi-component methods, wherein a soft component can form a seal for an air flow and a hard component the shaping of the ventilation device.

In a preferred embodiment, a spherical discharge nozzle is mounted on the valve member such that the directed air flow can be closed by rotating the discharge nozzle over a certain angle.

With regard to a possible illumination of the ventilation device, it is preferred that the area of the ventilation device that releases the air flow is illuminated. This can be done in particular from the interior of a supply line, so that the light source is not visible directly, but only by reflection from a vehicle occupant. In this case, it is both possible to illuminate the area of the ventilation device which is designed to generate the diffused air flow and the area which generates the directed air flow. For this purpose, LEDs are preferably used, which can be arranged in particular in the supply line of the ventilation device.

In a particularly preferred embodiment, the exhaust nozzle is made of a translucent or transparent material and optionally provided with a corresponding structural entry, so that the component lights up homogeneously when activated. For this purpose, a round light guide is advantageously provided, into which at least one light source, preferably an LED, DUO LED or RGB coupled in order to set the Ausströmdüse accordingly. The use of a light guide is essentially the homogeneous Lichtein- or light outcoupling of the exhaust nozzle. Furthermore, the use of a substantially circular light guide has the advantage not to be arranged directly in the air mass flow of the hollow cylinder or the base body in a disturbing manner.

Advantageously, a closing device may be provided, which has a plurality of openings, and is rotatably mounted, for example, on the valve member. If, for example, the second outflow nozzle for generating the third airflow is likewise configured by a plurality of openings on the valve member, the third airflow can be controlled particularly well by adjusting the overlap area between the openings of the closing device and the openings of the second outflow nozzle.

By rotating the closure device relative to the valve seat in which the openings of the second discharge nozzle can be provided, this coverage area can be adjusted between the openings of the various elements between the entire area of the openings and a completely suppressed coverage. This principle is basically also applicable to the first exhaust nozzle for generating the second air flow. However, it is particularly preferred in connection with the second exhaust nozzle for generating the third air stream.

Further advantages and features of the invention will become apparent from the following description of the figures and the totality of the claims.
