VEHICLE HVAC SYSTEM
An HVAC system for a vehicle is disclosed. The HVAC system may comprise an HVAC module configured to selectively direct conditioned air through an HVAC outlet; and an HVAC air distribution system including a duct operatively engaging the HVAC outlet to receive air flow therefrom, a top outlet configured to be positioned above an instrument panel, a heater outlet configured to be located below the instrument panel, and a diverter located in the duct and configured to selectively direct the air flow from the HVAC outlet through the duct to the top outlet and the heater outlet.
1 . An HVAC system for a vehicle comprising:
an HVAC module configured to selectively direct conditioned air through an HVAC outlet; and
an HVAC air distribution system including a duct operatively engaging the HVAC outlet to receive air flow therefrom, a top outlet configured to be positioned above an instrument panel, a heater outlet configured to be located below the instrument panel, and a diverter located in the duct and configured to selectively direct the air flow from the HVAC outlet through the duct to the top outlet and the heater outlet.
2 . The HVAC system of claim 1 wherein the duct includes a rotating duct portion mounted below the top outlet and configured to allow for rotation of the top outlet about a vertical axis.
3 . The HVAC system of claim 1 wherein the duct includes a swivel duct portion configured to allow for rotation of the top outlet about a horizontal axis.
4 . The HVAC system of claim 1 including a flexible duct connecting the HVAC outlet to an inlet to the duct, wherein the duct and the inlet to the duct are configured to move with the top outlet, and wherein the top outlet is movable into and out of the instrument panel such that movement of the top outlet out of the instrument panel will move the inlet relative to the diverter to cause the air flow to be directed through the top outlet and movement of the top outlet into the instrument panel will move the inlet relative to the diverter to cause the air flow to be directed through the heater outlet.
5 . The HVAC system of claim 1 including an air flow duct connecting the HVAC outlet to an inlet to the duct, and wherein the diverter includes a movable diverter member located adjacent to the inlet and a hand movable member configured to move the movable diverter member between a first position directing the air flow from the inlet to the top outlet and a second position directing the air flow from the inlet to the heater outlet.
6 . The HVAC system of claim 5 wherein the hand movable member includes a diverter rod connecting the movable diverter to a diverter handle via a cam, whereby movement of the diverter handle will cause the movable diverter to move relative to the inlet.
7 . The HVAC system of claim 1 including a flexible duct connecting to the HVAC outlet, and wherein the diverter includes a slide diverter slidable up and down on the duct and having an inlet engaging the flexible duct, and a diversion plate extending horizontally across the duct adjacent to the inlet such that sliding of the slide diverter upwards on the duct will direct the air flow above the diversion plate toward the top outlet and sliding of the slide diverter downwards on the duct will direct the air flow below the diversion plate toward the heater outlet.
8 . The HVAC system of claim 1 wherein the diverter includes a diverter rod supported by and movable with the top outlet, a top outlet valve configured to allow the air flow into the top outlet when the top outlet is raised to an extended position, and a flow opening in the diverter rod that is configured to permit the air flow to the heater outlet when the top outlet is lowered to a retracted position.
9 . The HVAC system of claim 8 wherein the HVAC air distribution system includes an extendable duct extending upward from the duct, with the top outlet mounted on and supported by the extendable duct.
10 . The HVAC system of claim 1 wherein the HVAC module includes a second HVAC outlet and the HVAC air distribution system includes a second duct operatively engaging the second HVAC outlet to receive the air flow therefrom, a second top outlet configured to be positioned above the instrument panel, a second heater outlet configured to be located below the instrument panel, a second diverter located in the second duct and configured to selectively direct the air flow from the second HVAC outlet through the second duct to the second top outlet and the second heater outlet.
11 . The HVAC system of claim 10 wherein the duct includes a rotating duct portion mounted below the top outlet and configured to allow for rotation of the top outlet about a vertical axis and the second duct includes a second rotating duct portion mounted below the second top outlet and configured to allow for rotation of the second top outlet about a second vertical axis.
12 . The HVAC system of claim 11 wherein the rotation duct portion and the second rotation duct portion are configured to allow the top outlet and the second top outlet, respectively, to face and direct the air flow onto a windshield.
13 . The HVAC system of claim 12 wherein the duct includes a swivel duct portion configured to allow for rotation of the top outlet about a horizontal axis and the second duct includes a second swivel duct portion configured to allow for rotation of the second top outlet about a second horizontal axis.
14 . The HVAC system of claim 11 wherein the duct includes a swivel duct portion configured to allow for rotation of the top outlet about a horizontal axis and the second duct includes a second swivel duct portion configured to allow for rotation of the second top outlet about a second horizontal axis.
15 . The HVAC system of claim 10 wherein the duct includes a swivel duct portion configured to allow for rotation of the top outlet about a horizontal axis and the second duct includes a second swivel duct portion configured to allow for rotation of the second top outlet about a second horizontal axis.
