Air conditioner system for automobiles
First Claim
1. An air conditioner system for a vehicle including a passenger compartment having a front-seat part and a rear-seat part, said air conditioner system comprising;
- (a) a front-seat air qonditioner unit including a main duct opening at one end thereof to the front-seat part, and means disposed in said main duct for adjusting the amount of heat exchange;
(b) a rear-seat blower unit including a duct opening at one end thereof to the rear-seat part, and an air mix chamber defined in said duct remotely from said one end thereof;
(c) at least two connecting passages connecting said air mix chamber with said main ducts at portions thereof located, respectively, upstream and downstream of said heat exchange amount adjusting means;
(d) at least one air mix door disposed upstream of said air mix chamber and movable for adjusting the proportion of air introduced into said air mix chamber through said connecting passages; and
(e) an electric control unit operatively connected with said air mix door for controlling the position of the latter, said electric control unit including(1) temperature setting means for presetting the temperature of air to be blown into the rear-seat part,(2) a sensor for detecting the temperature of air passing through said duct,(3) computing means for computing a control signal on the basis of the difference between the preset temperature and the detected temperature and(4) an actuator operatively connected to said air mix door and responsive to said control signal to actuate said air mix door.

Abstract
An air conditioner system for a vehicle includes a rear-seat blower unit and a rear-seat blower unit which are connected only by at least two connecting passages. Thus the air conditioner system is simple in structure and hence easy to construct. Further, any existing front-seat air conditioner unit can be used without reconstruction. The temperature of the blown-off air is automatically adjusted in accordance with the difference between the temperature preset by the temperature setting means and the temperature detected by the rear-seat mode sensor so that the temperature in the rear-seat part of the passenger compartment can be controlled at passenger'"'"'s desire, independently of the temperature of the front-seat part.
