DESC:TECHNICAL FIELD
[001] The embodiments herein generally relate to air outlet arrangement for HVAC (heating, ventilation and air conditioning) systems in vehicles and more particularly, to a modular air vent and duct mechanism for a HVAC (heating, ventilation and air conditioning) system in a vehicle, and a method for adjusting the position of air vent (air outlet) for directing the air in at least one of a plurality of predefined directions in an occupant compartment (passenger compartment) of a vehicle.
BACKGROUND
[002] Generally, heating, ventilation and air conditioning system (hereinafter called as HVAC system) in a vehicle is used to clean, cool, heat, regulate, ventilate and dehumidify the air entering a cabin of the vehicle thereby enhancing the comfort level of occupants in the vehicle. Typically, HVAC systems comprise an air conditioner unit for cooling/conditioning the air entering the cabin of the vehicle and a cabin heater for warming the air entering the cabin. In conventional vehicles, air vents are provided to a dashboard (instrumental panel) at fixed location and is operated by the occupants to receive the air towards corresponding occupant or to the desired location of the occupant by changing the angle and position of flaps provided on air vents. The air ducts are connected between the air vents and an air blower or corresponding components of the HVAC system to enable passage for air to/from the cabin. Usually the passenger and the driver tend to adjust two or three air vents to receive the air (hot/cool air) that is discharged towards them. The air vents should be located towards the respective occupant seating location or to the desired location of the occupant, for better discharging of air. However, packaging and arranging the air vents to corresponding occupant seating location or the desired location of the corresponding occupants is complex and is one of the challenges posed to the original equipment manufacturers (OEM).Most air vent arrangement in conventional vehicles are not matching rightly for one’s seating position and the height requirement. Further, the air from the air vents is not properly directed towards occupants like children or the occupants located to the rear portion of the vehicle. Furthermore, the arrangement of air vents in aforementioned vehicles requires higher capacity air conditioner thereby increasing an overall weight of the vehicle due to provision of higher number of air vents.
[003] Therefore, there exists a need for a modular air vent and duct mechanism for a HVAC system of a vehicle, and a method for adjusting the position of air vent (air outlet) for directing the air in at least one of a plurality of predefined directions in an occupant compartment (passenger compartment) of a vehicle, which obviates the aforementioned drawbacks.
OBJECTS
[004] The principal object of an embodiment of this invention is to provide a modular air vent and duct mechanism for a HVAC (heating, ventilation and air conditioning) system of a vehicle, which efficiently directs the air in a plurality of predefined directions in an occupant compartment (passenger compartment) without having multiple air vent arrangement.
[005] Another object of an embodiment of this invention is to provide a method for adjusting the position of air vent (air outlet) for directing the air in at least one of a plurality of predefined directions in an occupant compartment (passenger compartment) of a vehicle.
[006] Another object of an embodiment of this invention is to provide a modular air vent and duct mechanism for a HVAC (heating, ventilation and air conditioning) system of a vehicle, which eliminates the multiple air vent arrangement, and enables usage of reduced capacity air conditioner unit which in turn reduces costs, and reduces an overall weight of the vehicle.

moving at least one of a at least one air dispensing element 106, and a at least one connector 104 along at least one of a first predefined direction and a second predefined direction enables a second duct 102S to slide over corresponding portion of a first duct 102F along at least one of the first predefined direction and the second predefined direction respectively thereby moving said second duct 102S of at least one telescopic duct arrangement 102 between at least one of a plurality of first predefined positions and at least one of a plurality of second predefined positions respectively thereby facilitating movement of said air dispensing element 106 to corresponding at least one of a plurality of predefined positions, where the second predefined direction is opposite to the first predefined direction; and
adjusting said movable and adjustable air dispensing element 106 to at least one of a plurality of predefined angular positions for directing air from said air outlet 106A of said air dispensing element 106 towards corresponding at least one of a plurality of predefined directions in an occupant compartment of the vehicle.
19. The method 20 as claimed in claim 18, wherein said first duct 102F and said second duct 102S of said telescopic duct arrangement 102 is an inner duct and an outer duct respectively.
20. The method 20 as claimed in claim 18, wherein said first duct 102F and said second duct 102S of said telescopic duct arrangement 102 is an outer duct and an inner duct respectively.
