Abstract

An air conditioning display system for a vehicle comprising a vehicle'"'"'s air conditioner proper including a plurality of air intake ducts, a plurality of air discharge ducts, a plurality of dampers, and a fan unit, an air conditioner actuator actuating the dampers and the fan unit thereby introducing and discharging air into and out of the air conditioner proper, and a display device including a display panel carrying the picture of the vehicle body portions including the front seat, front glass and bonnet for displaying the flowing patterns of air into and out of the air conditioner proper under control of a control section. Lamps emitting light of, for example, red color and blue color are disposed behind the display panel and are selectively energized so that the occupant can readily visually confirm the flow of warm air or cold air from the duct outlets and also the flowing directions of air.

Claims

1. An air conditioning display system for a vehicle comprising a vehicle'"'"'s air conditioner proper including at least a plurality of air intake ducts, a plurality of air discharge ducts, a plurality of dampers disposed in said ducts for closing and opening said ducts, and a fan unit, air conditioner actuating means for actuating at least said dampers and said fan unit in said air conditioner proper thereby introducing and discharging air into and out of said air conditioner proper, and a display device mounted in said vehicle and including a display panel carrying the picture of the vehicle body portions including at least the front seat and its neighborhood for displaying on said display panel the flowing patterns of air out of said air conditioner proper at said vehicle body portions, said flowing patterns of discharged air being displayed on said display panel with strip-like display patterns extending substantially in the flowing directions of the air and having no arrowhead, wherein each of said strip-like display patterns for displaying the flowing patterns of air out of said air conditioner proper has a width increased gradually in the direction of air flow.

2. An air conditioning display system as claimed in claim 1, wherein said air conditioner actuating means includes lever means movable for selectively closing and opening said dampers in said air conditioner proper and a cam formed on said lever means, and said display device includes a plurality of microswitches provided in said air conditioner actuating means to be selectively turned on and off by being engaged by said cam, said microswitches being connected with said lamps for selectively energizing and deenergizing said lamps.

3. An air conditioning display system as claimed in claim 1, wherein said air conditioner actuating means includes lever means movable for selectively closing and opening said dampers in said air conditioner proper, and said display device includes a sealed slide switch consisting of a first electrode connected with a power source, and a plurality of second electrodes connected with said plurality of lamps, said first electrode coming into contact with said one or more second electrodes in response to manipulation of said lever means.
