Abstract
In an apparatus for distributing air flowing along a first path, the first path splits into second and third paths, so that both the second and third paths diverge from the first path. The second and third paths are at an angle of less than 180° to one another. A first door, is across the second path; and a second door, is across the third path. A common operating device rotates both doors, such that air is able to flow from the first path into the second and third paths, the flow being dependent on the position of rotation of the doors.
Claims17
Apparatus for distributing air in a motor vehicle, the air flowing along a first path, the apparatus comprising:
- (a) walls defining the first path aligned approximately along the longitudinal center line of the motor vehicle, a second path and a third path, the first path bifurcating into the second and third paths, the second and third paths diverging transversely from the first path towards opposite sides of the longitudinal center line of the motor vehicle and having respective portions disposed at an angle of less than 180° to one another;
- (b) a first door, rotatable about an axis disposed across a portion of the second path;
- (c) a second door, rotatable about an axis disposed across a portion of the third path;
- (d) an operating device for rotating the first door and second door, such that air is able to flow from the first path into the second and third paths, the flow being dependent on the positions of rotation of the first and second doors, respectively;
- and
- (e) a heater core disposed in the first path, whereby air in the second and third paths is heatable.
A vehicle air-conditioning system comprising:
- (a) walls defining a first longitudinally extending path aligned approximately along the longitudinal center line of the vehicle, a second path and a third path, the first path bifurcating into the second and third paths, the second and third paths diverging transversely from the first path towards opposite sides of the longitudinal center line of the vehicle and having respective portions disposed at an angle of less than 180° to one another;
- (b) an evaporator disposed in the first path;
- (c) a heater core disposed in the first path downstream of the evaporator;
- (d) a first door, rotatable about an axis disposed across a portion of the second path;
- (e) walls defining a fourth path and a fifth path, wherein the second path bifurcates into the fourth and fifth paths, the fourth path being offset from the first path and aligned substantially parallel to it, wherein air is able to flow from the second path into the fourth and fifth paths and out into the vehicle interior, flow being dependent on the position of rotation of the first door;
- (f) a second door, rotatable about an axis disposed across a portion of the third path;
- (g) walls defining a sixth path and a seventh path, wherein the third path bifurcates into the sixth and seventh paths, the sixth path being offset from the first path and aligned substantially parallel to it, wherein air is able to flow from the third path into the sixth and seventh paths and out into the vehicle interior, flow being dependent on the position of rotation of the second door.
Apparatus for distributing air into a vehicle cabin, the air flowing along a first path, the apparatus comprising:
- (a) means for defining the first path aligned approximately along the longitudinal center line of the vehicle, a second path and a third path, the first path bifurcating into the second and third paths, the second and third paths diverging transversely from the first path towards opposite sides of the longitudinal center line of the motor vehicle and having respective portions disposed at an angle of less than 180° to one another, the second and third paths having exit ends in fluid communication with the vehicle cabin;
- (b) means for selectively permitting air flow from the first path into the second path;
- and
- (c) means for selectively permitting air flow from the first path into the third path.
A method for distributing air from a first path into a vehicle cabin, comprising the steps of:
- (a) aligning the first path approximately along the longitudinal center line of the vehicle
- (b) bifurcating the first path into a second path and a third path, the second path and third path both diverging transversely from the first path towards opposite sides of the longitudinal center line of the vehicle such that the second path and third path are disposed at an angle of less than 180° to one another, the second and third paths having exit ends in fluid communication with the vehicle cabin;
- (c) selectively permitting air flow from the first path into the second path;
- and
- (d) selectively permitting air flow from the first path into the third path.
