Abstract

An outlet device (1) for ventilation of a vehicle interior has a housing (H) with an outer air guide surface (10a), and inner guide surface (30a), a guiding device (G), and an airflow adjustment member (63). The inner and outer air guide surfaces form an outlet flow channel (22) which extends between an air inlet orifice (11) and an air outlet orifice (12). The outlet flow channel (22) includes a first circumferential section (23a) and a second circumferential section (23b). An inlet air flow which passes the air inlet orifice (11) produces a first air flow component flowing therethrough and the second circumferential section (23b) produces a second air flow component flowing therethrough. The directions of the first and second circumferential sections meet each other in an intersecting point (P) which lies outside the housing (H). The airflow adjustment member allows changes to the ratio of the volumetric flows of the intersecting first and second air flow components.

First claim

The invention claimed is:

1. Outlet device for ventilation of a vehicle interior by generating an outlet flow, the outlet device comprising a housing with:
an outer air guide surface which extends between an air inlet orifice and an air outlet orifice lying contrary to the air inlet orifice with respect to a housing axis of the housing, wherein the outer air guide surface extends continuously around the housing axis,
an inner air guide surface which extends continuously around the housing axis and is spaced away from and faces toward the outer air guide surface, wherein the inner air guide surface and the outer air guide surface form an outlet flow channel, wherein an end section of the outlet flow channel which forms the air outlet orifice comprises at least a first circumferential section and a second circumferential section which are disposed with regard to the housing axis in a circumferential distance to each other, wherein imaginary extensions of the first circumferential section and the second circumferential section from and outward of the air outlet orifice meet each other in an intersection point which lies outside the housing at the side of the air outlet orifice, so that, caused by an inlet air flow which passes the air inlet orifice, a first air flow component flowing through the first circumferential section and a second air flow component flowing through the second circumferential section deflect each other after exiting the housing,
an airflow adjustment member which has a cross-sectional diameter perpendicular to the housing axis at a position along the housing axis which is smaller than a cross-sectional diameter of the outlet flow channel at the same position along the housing axis, and which is movable in a direction across the housing axis for obstructing an air flow in one of the first or second circumferential section and for changing the ratio of the volumetric flows of the first and second air flow component and thereby the direction of the outlet flow, and
a guiding device for guiding the airflow adjustment member in a direction across the housing axis.

2. Outlet device according to claim 1 , wherein the airflow adjustment member is disposed within the inner air guide surface in a neutral position of the airflow adjustment member when viewed across the housing axis.

3. Outlet device according to claim 1 , wherein the airflow adjustment member is disposed at the end of the inner air guide surface which faces the air inlet orifice.

4. Outlet device according to claim 1 , wherein the first circumferential section and the second circumferential section are lying diametrically opposite to each other.

5. Outlet device according to claim 1 , wherein the outlet device comprises a further guiding device which provides translational movement of the airflow adjustment member which is directed along the housing axis.

6. Outlet device according to claim 1 , wherein the airflow adjustment member is coupled to a motor which is configured to move the adjustment member.

7. Outlet device according to claim 1 , wherein the outlet device comprises an actuation rod which is fixed to the airflow adjustment member and which can be manually moved for obstructing an air flow in the outlet flow channel.

8. Outlet device according to claim 1 , wherein the outlet device comprises an inner body which is located in the housing and fixed thereto, the inner body comprising a first end facing the air inlet orifice, a second end being oriented contrary to the first end, wherein the inner body comprises the inner air guide surface which faces the outer air guide surface to form the outlet flow channel.

9. Outlet device according to claim 8 , wherein the outlet device comprises a second guiding device for guiding the airflow adjustment member in a direction along the housing axis, which outlet device comprises:
a through-hole which extends along the housing axis through the inner body,
a sleeve device which extends through the through-hole and which comprises a passageway extending through the sleeve device,
an actuation rod being moveably disposed within the passageway and guided therein, the actuation rod comprising a first rod end and a second rod end which is disposed contrary to the first rod end,
wherein the airflow adjustment member is fixed at the second rod end,
wherein the actuation rod extends through the passageway and is moveable in a direction of the housing axis between a first rod position and a second rod position,
wherein the adjustment member in the first rod position circumferentially contacts the outer air guide surface in a closing position and thereby closes the outlet flow channel and wherein the adjustment member in the second rod position opens the channel in an opening position,
wherein the first guiding device couples and guides the sleeve device at the housing across the direction of the housing axis of the housing when the airflow adjustment member is in the opening position.

10. Outlet device according to claim 1 , further comprising:
an inner body located in and fixed to the housing, wherein the inner body comprises the inner air guide surface that faces the outer air guide surface to form the outlet flow channel;
an actuation rod having one end fixed to the airflow adjustment member and a handling device formed at another end of the actuation rod,
wherein the guiding device guides the actuation rod, and thereby the airflow adjustment member, in said direction across the housing axis relative to the inner body.
