Vehicle having rear air duct and vent assembly and method
A vehicle having a body defining a cabin interior and having a window on a rearward facing surface, an air intake for receiving air from an exterior environment, an air blower for blowing the air in the cabin interior, and an air exhaust vent coupled to the body proximate the rearward facing window. A duct and vent assembly is operatively coupled to the exhaust vent for receiving the blown air and has a nozzle oriented to direct the blown air on the rearward facing window.
1 . A vehicle comprising:
a body defining a cabin interior and having a rear wall and a rear window defining a rearward facing surface;
an air intake for receiving air from an exterior environment;
an air blower for blowing the air in the cabin interior;
an air exhaust vent coupled to the rear wall of the body proximate the rearward facing surface; and
a duct and vent assembly operatively coupled to the exhaust vent for receiving the blown air and having a duct outlet oriented to direct the blown air on the rearward facing surface defined by the rear window.
2 . The vehicle of claim 1 , wherein the duct outlet is configured to direct blown air onto a camera.
3 . The vehicle of claim 1 , wherein the duct outlet is configured to direct blown air onto a rear light.
4 . The vehicle of claim 1 , wherein the duct outlet has a nozzle for directing the air in a desired stream.
5 . The vehicle of claim 1 , wherein the air blower is part of an HVAC system.
6 . The vehicle of claim 1 , wherein the user input comprises a touchscreen.
7 . The vehicle of claim 1 , wherein the rear window is located on an upper portion of a rear wall of the vehicle.
8 . The vehicle of claim 1 , further comprising a user input for selecting a mode of operation for controlling the airflow output by the duct and vent assembly.
9 . The vehicle of claim 8 , wherein the selected mode of operation includes controlling the blower for controlling the airflow output by the duct and vent assembly based on the selected mode of operation, and wherein the selected mode of operation comprises one of a dusty conditions mode that provides airflow for cleaning and a defrost mode that provides airflow and sets a temperature for the airflow directed on the rearward facing surface.
10 . The vehicle of claim 9 , wherein the selected mode of operation further includes an aero mode for enhancing airflow while the vehicle is traveling at higher speeds.
11 . A method of blowing air on a rear window of a vehicle, the method comprising the steps of:
receiving air from an external environment via an air intake;
blowing the received air with an air blower into a cabin interior of the vehicle;
exhausting the blown air through an air exit vent into a duct and vent assembly operatively coupled to a rear wall of the cabin interior of the vehicle; and
directing the blown air from the duct and vent assembly onto the rear window of the vehicle.
12 . The method of claim 11 , wherein the rear window is a rear window of the body defining the cabin interior.
13 . The method of claim 11 , wherein the duct and vent assembly is configured to direct blown air onto a camera.
14 . The method of claim 11 , wherein the duct and vent assembly includes a nozzle for directing the air in a desired stream.
15 . The method of claim 11 , wherein the duct and vent assembly is configured to direct blown air onto a rear light.
16 . The method of claim 11 , wherein the air blower is part of an HVAC system.
17 . The method of claim 11 , wherein the user input comprises a touchscreen.
18 . The method of claim 11 , further comprising the step of:
receiving a user input command to control the airflow, wherein the user input command controls the air blower, wherein the user input command selects a mode of operation for controlling the airflow output by the duct and vent assembly, and wherein the selected mode of operation comprises one of a dusty conditions mode that provides airflow for cleaning and a defrost mode that provides airflow and sets a temperature for the airflow directed on the rearward facing surface.
19 . The method of claim 18 , wherein the selected mode of operation further includes an aero mode for enhancing airflow while the vehicle is traveling at higher speeds.
