Abstract

Air controlling system of an air conditioner for a vehicle which controls conditioned-air with the temperature controlled in an air-conditioning case to be supplied to each demand part in a vehicle. The air controlling system of an air conditioner for a vehicle is equipped with a rear console duct and can discharge conditioned-air to not only the front seats, but the rear seats in a vehicle.

First claim

What is claimed is:

1. An air controlling system of an air conditioner for a vehicle interior, the vehicle interior having a plurality of demand parts, comprising:
an air-conditioning case having demand parts including a face vent, a defrost vent, a foot vent, a rear console vent for discharging conditioned air with a temperature controlled to each demand part, a first interacting passage introducing a portion of the conditioned air passing through the face vent into the rear console vent, and a second interacting passage introducing a portion of the conditioned air passing through the foot vent into the rear console vent;
a vent door that opens the face vent and the first interacting passage and makes the air conditioned air flow through the face vent and the first interacting passage and that closes the face vent and the first interacting passage and prevents the conditioned air from flowing into the face vent and the first interacting passage;
a foot door that opens and closes the foot vent;
a rear console door connected to and rotating together with the foot door; and
a door switching control unit that controls switching of the doors in accordance with selected modes, wherein the door switching control unit is configured to control, in response to a foot mode, the rear console door to open the second interacting passage while closing the first interacting passage when the door switching control unit controls the foot door to open the foot vent to make the conditioned air passing through the foot vent flow into the rear console vent through the second interacting passage, thereby improving cooling and heating efficiency by enabling conditioned air to flow through the rear console vent when the air controlling system is in the foot mode in which the face vent is closed which would otherwise also close the rear console vent.

2. The air controlling system of claim 1 , wherein the door switching control unit controls the rear console vent to open through the first interacting passage by switching the rear console door such that the first interacting passage opens and the second interacting passage closes, in a face mode in which the face vent opens and the foot vent closes.

3. The air controlling system of claim 2 , wherein the rear console door includes a rotary shaft disposed at a vicinity of the first interacting passage and the second interacting passage, a switching door disposed rotatably about the center of the rotary shaft and selectively opening/closing the first interacting passage and the second interacting passage, and a connecting rod having one end hinged to the foot door and the other end hinged to the switching door.

4. The air controlling system of claim 1 , wherein the door switching control unit controls the rear console vent to open through the first interacting passage and the second interacting passage by switching the rear console door such that the first interacting passage and the second interacting passage partially open, in a bi-level mode in which the face vent and the foot vent partially open.

5. The air controlling system of claim 4 , wherein the rear console door includes a rotary shaft disposed at a vicinity of the first interacting passage and the second interacting passage, a switching door disposed rotatably about the center of the rotary shaft and selectively opening/closing the first interacting passage and the second interacting passage, and a connecting rod having one end hinged to the foot door and the other end hinged to the switching door.

6. The air controlling system of claim 1 , wherein the rear console door includes a rotary shaft disposed at a vicinity of the first interacting passage and the second interacting passage, a switching door disposed rotatably about the center of the rotary shaft and selectively opening/closing the first interacting passage and the second interacting passage, and a connecting rod having one end hinged to the foot door and the other end hinged to the switching door.

7. The air controlling system of claim 6 , wherein the rotary shaft is disposed at the upper end of the switching door and the ends of the connecting rod are connected to portions lower than the rotational centers of the foot door and the switching door.

8. The air controlling system of claim 7 , wherein when the foot door rotates counterclockwise such that the foot vent opens in response to the foot mode, the switching door with the lower portion pushed by the connecting rod correspondingly operates counterclockwise, so that the first interacting passage closes and the second interacting passage opens.

9. The air controlling system of claim 7 , wherein when the foot door rotates clockwise such that the foot vent closes in response to a face mode, the switching door with the lower portion pulled by the connecting rod correspondingly operates clockwise, so that the first interacting passage opens and the second interacting passage closes.

10. The air controlling system of claim 7 , wherein when the foot door rotates counterclockwise or clockwise such that the foot vent partially opens in response to a bi-level mode, the switching door correspondingly operates in the same direction as the rotational direction of the foot door, while the lower portion is pushed or pulled by the connecting rod, so that the first interacting passage and the second interacting passage partially open.
