Description

[0001] The present invention relates to an air outlet, particularly for a vehicle ventilation system. Furthermore, the invention relates to a ventilation system with such an air outlet and a corresponding air outlet system.

[0002] Vehicle ventilation systems generally use air outlets or air discharge nozzles that allow for precise control of the outgoing air jet. These air outlets serve to supply fresh air, in particular, to the vehicle interior.

[0003] The airflow enters the air duct (defined by the housing wall of the air outlet) through an inlet opening at the air intake area of ​​the air outlet, passes through this duct, and finally exits through an outlet opening at the air outlet area into the interior of a vehicle (e.g., a car or truck). The airflow generally follows a main flow direction, which can run at least substantially parallel to a longitudinal axis of the air outlet housing.

[0004] In known air outlets, the airflow is deflected from the main flow direction by one or more air guide elements, such as pivotable air guide vanes or fixed air guide elements. In addition to the air guide elements, the housing of the air outlet, which defines the air duct, can also serve to deflect the air from the main flow direction.

[0005] In particular, the area of ​​an air vent visible from the vehicle's interior, especially the air outlet of the housing, is increasingly used to attract consumer attention and enhance the overall appearance of the vehicle. The interior design of a vehicle is becoming an increasingly important differentiating factor, intended to create a style and ambiance that reflects the buyer's preferences.

[0006] Therefore, in this context there is also a need for air vents that blend harmoniously into the design theme of the vehicle interior.

[0007] A particular desire within the professional community is to specify, in the simplest possible way, an air outlet that – viewed from inside the vehicle – reflects the appearance of an aircraft jet nozzle, whereby the airflow-regulating and / or airflow-deflectoring elements used to adjust the main direction of the airflow emitted by the air outlet and / or to adjust the amount of airflow emitted by the air outlet per unit of time are as invisible as possible.

[0008] In particular, the air outlet should be designed in such a way that, when the required directability of the airflow is required, only the lowest possible pressure loss occurs.

[0009] Furthermore, there is a need to create, in particular, such an air outlet so that a particularly advantageous adjustability of the air outlet can be realized in a particularly advantageous way.

[0010] This problem is solved in particular by the subject matter of independent claim 1, wherein advantageous further developments of the air outlet according to the invention are specified in the dependent claims.

[0011] Accordingly, the present invention relates in particular to an air outlet for a vehicle, wherein the air outlet comprises the following: • a housing with an air inlet area and an air outlet area; • a flow body arranged at least partially or partially and preferably completely within the housing and around which an airflow passing through the housing can flow, and which is stationary relative to the housing; and • an air guide element arrangement with at least one air guide element, wherein the air guide element arrangement is pivotably mounted relative to the housing and relative to the flow body between a neutral position and at least one deflected position about at least one axis of rotation.

[0012] According to the invention, it is particularly provided that the air guide element arrangement is arranged upstream of the flow body, at least in its neutral position - viewed in a main flow direction of the airflow through the housing - in particular such that the air guide element arrangement is not visually visible in a top view of the air outlet area of ​​the housing of the air outlet.

[0013] According to implementations of the air outlet according to the invention, the air guide element arrangement comprises a plurality of air guide elements that run at least substantially parallel to one another, and in particular are fixedly arranged relative to one another. When the air guide element arrangement is adjusted, these elements pivot together about one of the at least one axes of rotation as a common axis of rotation. The air guide elements of the air guide element arrangement particularly form a lamellar structure. For example, the air guide element arrangement is designed as an integrally formed or rigidly assembled component with several lamellae, which is pivotably mounted in the housing. Preferably, the air guide element arrangement, viewed in cross-section along the flow direction, has two outer lamellae and at least one inner lamella, which is arranged between the outer lamellae, e.g.two inner lamellae, so that there are a total of four lamellae, or three inner lamellae, so that there are a total of five lamellae.

[0014] In this context, it is advantageous that, at least in the neutral position of the air guide element arrangement, an air channel is formed between two adjacent air guide elements of the particularly lamellar structure, through which a part of the airflow flowing through the housing flows.

[0015] For this purpose, it is conceivable that at least one outer air guide element and preferably both opposing outer air guide elements of the particularly lamellar structure and / or a wall section of the housing in the area of ​​the air guide element arrangement are designed in such a way that, particularly in the neutral position of the air guide element arrangement and preferably both in the neutral position and in the at least one deflected position of the air guide element arrangement, no air channel through which air flows is formed between the at least one outer air guide element and the wall section of the housing.

[0016] Advantageously, the wall section of the housing is provided that it is at least partially or partially curved and, in particular, is designed to be complementary to an outer surface of the at least one outer air guide element, wherein the outer surface of the at least one outer air guide element is, in particular, at least partially or partially convexly curved.

[0017] According to implementations of the air outlet according to the invention, it is provided that - at least in a neutral position of the air guide element arrangement - the flow body is surrounded or can be surrounded by air at least on two opposite sides.

[0018] In this context, it is conceivable that, viewed in cross-section along the flow direction, the flow body has an egg-shaped, oval-shaped or teardrop-shaped form.

[0019] Alternatively or additionally, in embodiments of the air outlet according to the invention, it is provided that a wall area of ​​the housing in the area of ​​the flow body runs at least substantially parallel to a surface of the flow body opposite the wall area of ​​the housing, and wherein - at least in the neutral position of the air guide element arrangement - a flow channel with in particular an at least substantially constant effective flow cross-section is formed between the wall area of ​​the housing and the surface of the flow body opposite the wall area of ​​the housing.

[0020] Alternatively or additionally, in embodiments of the air outlet according to the invention, it is provided that in a fully deflected position of the air guide element arrangement, at least one air guide element of the air guide element arrangement blocks at least one area of ​​the flow channel formed between the wall area of ​​the housing and the surface of the flow body opposite the wall area of ​​the housing from air flow.

[0021] According to implementations of the air outlet according to the invention, the air guide element arrangement is gimbal mounted.

[0022] On the other hand, it is conceivable that the air outlet has a control element, which can be operated manually, for manipulating the air guide element arrangement as required, wherein the control element is preferably at least partially or partially incorporated or integrated into the flow body, or wherein the control element is preferably arranged at least partially or partially on the housing of the air outlet.

[0023] In this context, it is advantageous for the control element to be mounted and designed in a cardan-like manner, so that when the control element is actuated, the air guide element arrangement is manipulated in the opposite direction.

[0024] According to implementations of the air outlet according to the invention, the housing has a release edge at the air outlet area of ​​the housing that projects into and, in particular, jumps into a flow channel of the air outlet.

[0025] Alternatively or additionally, the air outlet may have a device designed to eliminate, or at least reduce or weaken, a Coandă effect which occurs particularly when the airflow is deflected from the main flow direction at an area of ​​the inner wall of the housing and / or at a wall area of ​​the at least one air guide element.

[0026] Various solutions are possible for implementing the device to eliminate or reduce / weaken the Coandă effect, and these can be combined in any way.

[0027] According to embodiments of the air outlet according to the invention, the device for eliminating or reducing / weakening the Coandă effect is designed to form, at least partially and / or regionally, a flow separation and / or a separation bubble at least partially and / or regionally on the area of ​​the inner wall of the housing and / or on the wall area of ​​the at least one airflow-regulating and / or airflow-deflectoring element and / or on the wall area guiding the airflow inside and / or outside the housing when the airflow is passed through the outlet, particularly with airflow deflection.

[0028] In other words, the device for eliminating or reducing / attenuating the Coandă effect is specifically designed to deliberately induce boundary layer shedding in the relevant area of ​​the air outlet.

[0029] Boundary layer separation is a fluid-mechanical effect that causes the flow to deviate from the contour of a body or surface. Downstream of the separation point, a turbulent zone forms between the laminar main flow and the body or wall contour; this is sometimes also referred to as dead water or wake.

[0030] Boundary layer separation is caused by a counteracting pressure increase. This occurs, for example, when the relevant wall area of ​​the air outlet, where boundary layer separation and thus flow separation is to be induced, has an edge or step projecting into the main flow.

[0031] In order to eliminate, in particular, the Coandă effect during the airflow around the at least one airflow-regulating and / or airflow-deflectoring element that is movable relative to the housing and, in particular, pivotably mounted, it is preferred that the device for eliminating or reducing / weakening the Coandă effect is designed to form a corresponding flow separation and / or a separation bubble only when the air outlet is flowing through with airflow deflection, and in particular with a minimum deflection of the airflow, on the area of ​​the inner wall of the housing and / or on the wall area of ​​the at least one airflow-regulating and / or airflow-deflectoring element and / or on the wall area inside and / or outside the housing that guides the airflow.

[0032] In particular, the device for eliminating or reducing the Coandă effect should be designed to generate a flow separation with a separation bubble downstream of the separation area when air flows through the housing, especially with airflow deflection, in such a way that the flow does not reattach to the area of ​​the inner wall of the housing and / or to the wall area of ​​the at least one airflow-regulating and / or airflow-deflectoring element and / or to the wall area guiding the airflow inside and / or outside the housing downstream of the separation area.

[0033] According to implementations of the air outlet according to the invention, an edge, in particular an edge of an inwardly projecting area, is formed in order to create a flow separation and / or a separation bubble in an area of ​​the inner wall of the housing and / or in a wall area of ​​the at least one airflow-regulating and / or airflow-deflectoring element and / or in an airflow-guiding wall area inside and / or outside the housing, against which the airflow would at least partially or partially adhere without the device for eliminating or reducing / weakening the Coandă effect, and / or which contour the airflow would at least partially or partially follow without the device for eliminating or reducing / weakening the Coandă effect.

[0034] In other words, according to the invention, a boundary layer separation and thus a flow separation is deliberately provoked, as a result of which a turbulent flow region is created downstream of the separation point, so that the airflow cannot follow the contour of the wall region.

[0035] This measure, in a sense, represents an overcoming of a common misconception in the field, as the design and layout of an air outlet typically aims for laminar airflow. However, by selectively inducing boundary layer separation, the Coandă effect can surprisingly be eliminated. Consequently, the deflection range for the airflow is independent of the Coandă effect, and, in particular, optimal airflow deflection with consistent quality is achieved across the entire deflection range.

[0036] According to further developments of the latter embodiment variant, in which the device for eliminating or reducing / weakening the Coandă effect is formed by an edge, in particular by an edge of an inwardly retracting area, it is provided that the edge is formed in an area in which, due to a narrowing of the effective flow cross-section, at least locally an increased flow velocity of the airflow occurs.

[0037] This measure is based on the understanding that in the area where, due to a narrowing of the effective flow cross-section, there is at least a locally increased flow velocity of the airflow, the static pressure has a minimum, which simplifies boundary layer separation.

[0038] Alternatively or in addition to the implementation variant in which the device for eliminating or reducing / weakening the Coandă effect is implemented by an edge, in particular by an edge of an inwardly retracting region, it is conceivable that the device for eliminating or reducing / weakening the Coandă effect is implemented at least partially as an active device for influencing the boundary layer.

[0039] One possibility for such an active device for influencing the boundary layer is to blow air onto the boundary layer at the area of ​​the inner wall of the housing and / or at the wall area of ​​the at least one airflow-regulating and / or airflow-deflectoring element and / or at the wall area inside and / or outside the housing that guides the airflow. In particular, the boundary layer is blown onto at least one surface of the air outlet that bounds the air duct.

[0040] According to implementations of the active device for boundary layer control, it is provided that the active device for boundary layer control has at least one preferably slot-shaped discharge opening, which serves to introduce additional air, particularly as required or continuously, into the airflow flowing past the area of ​​the inner wall of the housing and / or into the airflow flowing past the wall area of ​​the at least one airflow-regulating and / or airflow-deflectoring element and / or into the airflow-carrying wall area inside and / or outside the housing.

[0041] It is particularly preferred that the active device for influencing the boundary layer is designed to introduce additional air into the airflow according to the Venturi principle, especially as required, via the preferably slot-shaped discharge opening.

[0042] Exemplary embodiments of the air outlet according to the invention are described in more detail below with reference to the accompanying drawings.

[0043] They show: Fig. 1. Schematically and in a cross-sectional view, the exemplary embodiment of an air outlet according to the invention in a state in which the air guide element arrangement of the air outlet is in a (fully) deflected position; and Fig. 2. Schematic and in a sectional view, the exemplary embodiment of the air outlet according to Fig. 1, namely in a state in which the air guide element arrangement is in a neutral position.

[0044] An exemplary embodiment of the air outlet 1 according to the invention is described below with reference to the accompanying drawings. In detail, Fig. Figure 2 shows air outlet 1 schematically and in a sectional view, where air outlet 1 is in its neutral position. Fig. In contrast, in position 1 the air outlet 1 is in a position in which the air flowing through the air outlet 1 is deflected upwards in a maximum vertical direction.

[0045] The air outlet 1 has a housing 2 which forms an air channel. Accordingly, the housing 2 of the air outlet 1 has an upstream air inlet area 3 and a downstream air outlet area 4.

[0046] Inside the housing 2 a flow element 5 is arranged, which at least in the neutral position of the air outlet 1 according to Fig. 2 is completely or at least on both sides surrounded by the airflow F flowing through the housing 2. The flow body 5 is fixed in position relative to the housing 2.

[0047] In order to effect an airflow deflection, the air outlet 1 further comprises an air guide element arrangement 6 with several air guide elements 7, 7.1. The air guide element arrangement 6 is positioned relative to the housing 2 and relative to the flow body 5 between a neutral position (cf. Fig. 2) and at least one deflected position (see Fig. 1) mounted so as to pivot about a pivot axis 8.

[0048] The representation in Fig. 2 can be seen in particular that the air guide element arrangement 6 in its neutral position - viewed in a main flow direction of the airflow through the housing 2 - is arranged upstream of the flow body 5, such that in a top view of the air outlet area 4 of the housing 2, the air guide element arrangement 6 is not optically visible.

[0049] The representation in Fig. Figure 1 shows that the air guide element arrangement 6 has several air guide elements 7, 7.1 that run at least substantially parallel to each other and which are pivoted together about the common axis of rotation 8 when the air guide element arrangement 6 is adjusted. The air guide elements 7, 7.1 of the air guide element arrangement 6 form a lamellar structure.

[0050] In the Fig. In the neutral position of the air guide element arrangement 6 shown in Figure 2, an air channel is formed between two adjacent air guide elements 7, 7.1 of the lamellar structure of the air guide element arrangement 6, through which a part of the airflow flowing through the housing 2 of the air outlet 1 flows.

[0051] Also the representation in Fig. It can be seen from Figure 2 that the outer air guide elements 7.1 of the lamellar structure and a corresponding wall section 9 of the housing 2 in the area of ​​the air guide element arrangement 6 are designed in such a way that in the neutral position of the air guide element arrangement 6 no air channel through which air can flow is formed between the outer air guide elements 7.1 and the wall section 9 of the housing 2.

[0052] In the embodiment of the air outlet 1 according to the invention shown schematically in the drawings, this also applies in the deflected position of the air guide element arrangement 6, as shown in the illustration in Fig. 1 can be taken from it.

[0053] For this purpose, it is specifically provided that the wall section 9 of the housing 2 is at least partially or regionally curved and is designed to be complementary to an outer surface of the corresponding outer air guide element 7.1. In particular, the outer surface of the corresponding outer air guide elements 7.1 is designed to be at least partially or regionally convexly curved.

[0054] In the neutral position of the air guide element arrangement 6, the flow body 5 is surrounded or can be surrounded by air on two opposite sides. In the maximally deflected position of the air guide element arrangement 6, however, the flow body 5 is surrounded or can be surrounded by air on only one side.

[0055] In the exemplary embodiment of the air outlet 1 according to the invention shown in the drawings, the flow body has an egg-shaped, oval-shaped or teardrop-shaped cross-section when viewed along the flow direction.

[0056] Furthermore, in the embodiment of the air outlet 1 according to the invention shown in the drawings, a wall region of the housing 2 in the area of ​​the flow body 5 runs at least substantially parallel to a surface of the flow body 5 opposite the wall region of the housing 2. At least in the neutral position of the air guide element arrangement 6, a flow channel with an at least substantially constant effective flow cross-section is formed between the wall region of the housing 2 and the surface of the flow body 5 opposite the wall region of the housing 2.

[0057] For example, in Fig. In the fully deflected position of the air guide element arrangement 5 shown in Figure 1, at least one area of ​​the flow channel formed between the wall area of ​​the housing 2 and the surface of the flow body 5 opposite the wall area of ​​the housing 2 is blocked for airflow by, in particular, the outer air guide element 7.1.

[0058] The air guide element arrangement 6 is in particular gimbal-mounted.

[0059] The drawings further indicate that the air outlet according to the invention has a control element 10, which is particularly operable manually, wherein the control element 10 is at least partially or partially received or integrated into the flow body 5. Alternatively, it is also conceivable that the control element 10 is at least partially or partially arranged on the housing 2 of the air outlet 1.

[0060] The control element 10 is also in particular gimbal-mounted and designed to manipulate the air guide element arrangement 6 in the opposite direction when the control element 10 is actuated.

[0061] It can also be seen from the drawings that the housing 2 of the air outlet 1 has a release edge 11 at the air outlet area 4 which projects into and in particular jumps into a flow channel of the air outlet 1.

[0062] In the air outlet 1 according to the invention, no movements of the airflow-guiding elements, i.e. the air guide arrangement 6 with the air guide elements 7, 7.1, are visible from the vehicle interior.

[0063] Further requirements for low pressure loss with required directability of the air to reach target points are also met with the proposed solution.

[0064] The proposed solution also involves a simple kinematics.

[0065] To achieve air deflection, according to Fig. 1. Upstream of the flow body 5, an air guide element arrangement 6 with lamellar structures is pivoted about at least one axis of rotation 8. This creates at least a partially closed area and at least a partially open area in conjunction with the flow body 5. As a result, the air is directed primarily into the area around the flow body 5 that has been opened by the air guide element arrangement 6. The airflow FF is guided between the housing 2 and the flow body 5 and directed towards the outflow edge / separation edge 11.

[0066] The air deflection preferably occurs through an interaction of the shape of the housing 2, the shape of the flow body 5 and the outflow edge / separation edge 11.

[0067] In the neutral position of the air guide element arrangement 5, the airflow part body or flow body 5 is uniformly surrounded by flow on two opposite sides.

[0068] The result is a neutrally oriented airflow FF ( Fig. 2). Description of kinematics:

[0069] In the proposed concept for the suspension of the air guide element assembly 6, manual operation preferably utilizes a gimbal suspension. This allows the air guide element assembly 6 to pivot about two axes and thus into any desired position around a pivot point.

[0070] Similarly, the control element 10 is preferably suspended.

[0071] By appropriately coupling the control element 10 and the air guide elements 7, 7.1, an opposing movement of the air guide element arrangement 6 and the control element 10 is achieved. If the control element 10 is moved in the direction of the expected airflow, e.g. downwards, the air guide elements 7, 7.1 are moved in an opposing direction such that the air guide elements 7, 7.1 direct the air into the upper area between the airflow subbody or flow body 5 and the housing 2, or at least partially block the lower area.

[0072] The airflow F is directed downwards via the shape of the housing 2), the shape of the airflow subbody or flow body 5 and the design of the outflow edge / separation edge 11.

[0073] This applies analogously in the same way to outflow in a different direction.

[0074] The invention is not limited to the exemplary embodiment of the air outlet according to the invention shown in the drawings, but results from a combination of all the features disclosed herein.
