Description

The invention relates to a ventilation device for a motor vehicle with at least one air outlet, in which at least one pivotable air guide element is arranged. Furthermore, an adjusting wheel is provided, which is provided for adjusting an air flow flowing through the air outlet, wherein the setting wheel is illuminated.

Ventilation devices and methods of the type mentioned are known in the art. For driving in darkness, it is necessary to illuminate controls of a motor vehicle to make them discoverable for a driver and a passenger. In motor vehicles lighting systems for ventilation devices are therefore implemented in many variants. In this case, air nozzles are illuminated via a light source within the housing, ie behind air-conducting elements. This requires a lot of effort to integrate the lighting, especially in moving parts. In particular, rotatably mounted air guide elements are regularly not illuminated.

From the DE 20 2013 105 590 U1 an illuminable air guide element for an air vent is known, wherein the air vent has a housing, an air outlet opening and a connection to an air supply shaft and the air guide element is pivotably mounted in the housing via at least one bearing journal, wherein the air guide element comprises a first light guide consisting of transilluminable plastic, a bearing in the housing of the Luftausströmers pivotally mounted bearing pin, wherein in the housing on the bearing pin a light source for introducing light into the first light guide is arranged and the first light guide extends at least over a longitudinal region of the air guide, wherein light introduced via the light source can be output via a light exit surface of a parallel to a front, the air outlet opening facing the longitudinal edge of the air guide element extending first light exit portion and the first light guide to d he the light exit surface of the first light exit portion opposite side has a surface structure which causes a reflection of the introduced light and is designed so that is introduced via the light source in the first light guide light introduced substantially uniformly over the light exit surface of the first light exit portion, wherein the surface structure extends at least over a region of the light exit surface of the first light exit section.

The object of the invention is to develop ventilation devices of the type mentioned in that a simpler and better lighting of the ventilation device is possible.

The object is achieved by a ventilation device according to claim 1 and by a method for illuminating a ventilation device according to the independent claim 9. Further embodiments of ventilation device and method are the subject of the dependent claims.

An inventive ventilation device for a motor vehicle has at least one air outlet, in which at least one pivotable air guide element is arranged. The pivotable air guide element is rotatably mounted on at least one side at a bearing point. The spoiler element can be mounted at more than one point. The spoiler directs air from an air inlet, which may be coupled to, for example, a central air supply, to an air outlet.

Furthermore, an adjusting wheel is provided, which is provided for adjusting an air flow flowing through the air outlet. With the help of the adjusting wheel can thus affect the amount of air and / or flow direction of the ventilation device leaving the air flow.

The wheel is illuminated. The lighting is used to facilitate locating the wheel when driving in the dark. Furthermore, the adjustment of the setting wheel in darkness can be detected.

According to the invention, it is provided that a lighting element is provided for illuminating the setting wheel, the air guiding element having a light-conducting region, the light-conducting region optically coupling to the setting wheel such that light is guided by the setting wheel into the light-guiding region, so that the air guiding element is illuminated. The photoconductive region can be translucent.

In this way, in addition to the setting wheel and the air guide can be illuminated, whereby the adjustment of the air guide element can be checked simultaneously with the setting of the setting wheel. This allows a better visibility of the corresponding setting of the ventilation device and thus to adjust this easier while driving on the needs of the driver.

A first further embodiment of the ventilation device provides that the luminous element is arranged in the setting wheel. This makes it possible to achieve a simple illumination of the setting wheel.

Alternatively, it may be provided that the luminous element is arranged on a housing of the ventilation device and optically couples the setting wheel to the luminous element. This allows the luminous element to be arranged in a stationary manner relative to the motor vehicle, which simplifies the energy supply of the luminous element. The optical coupling of the light element to the setting wheel illumination of the setting wheel is made possible.

Another aspect of the ventilation device according to the invention provides that the coupling point is arranged on the air guide element in the bearing point. The bearing point is spatially stationary relative to the ventilation device, so that by the arrangement of the coupling point at the bearing point a coupling of light in each relative position is possible. Alternatively, the coupling may be arranged on a rotation axis of the air guide element.

A further aspect of the ventilation device according to the invention provides that the air guide element has at least one lamella, wherein the lamella has a light-conducting region, which optically couples to the light-conducting region of the air guide element. Thus, a lighting de lamella can be achieved by the photoconductive area, so that the position of the lamella is recognizable.

Another aspect of the present ventilation device according to the invention provides that the air guide element and / or the lamella have a non-light-conducting region, wherein the light-conducting region and the non-light-conducting region are formed in several pieces and / or produced in multi-component injection molding. In this way, the formal shape of the air guide element and / or lamella can be decoupled from the embodiment. A more targeted design of the illuminated areas can thus be achieved.

Another further aspect of the ventilation device provides that the lighting element and the setting wheel interact in such a way that the position of the setting wheel influences the emitted brightness. In this way, an optical feedback on the setting of the ventilation device on the brightness can be done, for example, in a weak ventilation setting on a relatively dark lighting. A high maximum airflow can then be represented by a high brightness. By comparing different, mounted in the vehicle interior corresponding ventilation devices, a driver can thus quickly recognize which ventilation device is set as and possibly modify their setting.

The ventilation device may in particular be a roller nozzle. Conventional roller nozzles are difficult to illuminate, the illumination according to the invention therefore brings particular advantages in roller nozzles.

A first independent subject of the present invention relates to a method for illuminating a ventilation device of a motor vehicle, which has at least one air outlet, in which at least one pivotable air guide element is arranged, which is rotatably mounted on at least one side at a bearing point, wherein the ventilation device further comprises a thumbwheel has, which is provided for adjusting an air outlet flowing through the air stream.

In the context of the method, it is provided that light is coupled into the setting wheel by means of a luminous element, the air guiding element having a light-conducting and a non-light-conducting region, light being coupled into the light-conducting region of the air guiding element by the setting wheel. By this coupling of light into the air guide element by means of the adjusting wheel, the air guide element can be illuminated, so that the setting of the air guide element is visible in the dark.

The ventilation device is in particular a ventilation device according to the previously described aspect of the invention.

A first further aspect of the method according to the invention provides that the lighting element and setting wheel interact in such a way that a position of the setting wheel influences the indicated brightness.

The invention will be explained with reference to an embodiment. The single figure shows schematically a frontal view of a roller nozzle 2 ,

The roller nozzle 2 has a housing 4 on, which is intended for installation in a motor vehicle. In the case 4 is an air guide 6 installed. The air guiding element directs air from an air intake, which is arranged on a rear side and is not shown, to an air outlet 8th , The air inlet may be connected to a central air supply of the motor vehicle.

The air guide 6 is rotatably mounted along a rotation axis Y, so that the air outlet 8th opposite the housing 4 can be pivoted. For storage of the air guide element 6 are storage points 10 . 12 intended. The air guide 6 also has adjustable slats 14 on, with the help of which the air flow can be passed. The position of the slats 14 as well as the position of air guide 6 can be reached by means of a handle 16 to adjust. The handle 16 can be placed up and down as well as to the right and to the left.

To regulate the strength of the air flow of the roller nozzle 2 is a wheel 18 intended. The thumbwheel 18 can be adjusted by turning from a maximum position to a closed position, whereby the flow connection between the air inlet and the air outlet is cut off.

In the wheel 18 is a lighting element 20 (dashed) provided. The thumbwheel 18 has photoconductive indices 22 on, by means of the luminous element 20 be illuminated. light element 20 and thumbwheel 18 are coupled so that the adjustment of the setting wheel 18 changed the brightness of the illuminated indices. This can be done either via a change in the brightness of the luminous element or by the coupling between the luminous element 20 and thumbwheel 18 respectively.

The thumbwheel 18 has at its one cylindrical end face a Lichtauskoppelstelle 24 on, which is arranged on the rotation axis Y. The air guide 6 has one to the decoupling point 24 adjacent coupling site 26 on, so light from the wheel 18 in the air guide 6 can be coupled. The light can be transmitted via light-guiding areas 28 in the air guide 6 be distributed.

The air guide 6 is produced by two-component injection molding. One component in two-component injection molding is the photoconductive component, another component is not photoconductive. In this way can be in the air guide 6 Form light guides to bring the light to desired locations and non-light-transmitting areas 30 to determine.

Alternatively or additionally, the air guide 6 be formed in several pieces, with individual pieces are completely light-conducting, completely opaque or in the two-component injection molding partially light-conducting, partly opaque. So it is possible to light to the handle 16 to guide, so the handle 16 a photoconductive area 28 having. This facilitates the findability of the handle 16 ,

The light element 20 can in a variant in the wheel 18 be integrated. In another variant, the lighting element 20 in the case 4 be integrated, with the thumbwheel 18 then having a Ankoppelbereich to light from the light emitting element 20 in the wheel 18 couple.

The roller nozzle shown in the single figure 2 is shown as a single nozzle, but it can also be designed as a multi-nozzle, as it is arranged for example in the middle of a vehicle interior to illuminate the driver and front passenger.
