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.

Claims

1. An air controlling system of an air conditioner for a vehicle, comprising:

an air-conditioning case that has a face vent, a defrost vent, a foot vent, and a rear console vent for discharging conditioned-air with the temperature controlled to each demand part, and where a first interacting passage allowing the face vent and the rear console vent to interact with each other and a second interacting passage allowing the foot vent and the rear console vent to interact with each other are formed;

a vent door that selectively opens/closes the face vent;

a foot door that selectively opens/closes the foot vent;

a rear console door that controls opening/closing of the rear console vent, as the first interacting passage and the second interacting passage selectively open/close, in response to the operation of the foot door; and

a door switching control unit that controls switching of the doors in accordance with modes and controls the rear console vent to open through the second interacting passage by switching the rear console door such that the first interacting passage closes and the second interacting passage opens, in a foot mode in which the face vent closes and the foot vent opens.

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 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.

4. The air controlling system of claim 1, wherein the rear console door includes a rotary shaft disposed close to 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.

5. The air controlling system of claim 4, 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.

6. The air controlling system of claim 5, 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.

7. The air controlling system of claim 5, wherein when the foot door rotates clockwise such that the foot vent closes in response to the 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.

8. The air controlling system of claim 5, wherein when the foot door rotates counterclockwise or clockwise such that the foot vent partially opens in response to the bilevel mode, the switching door correspondingly operates counterclockwise or clockwise, that is, 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.

9. The air controlling system of claim 2, wherein the rear console door includes a rotary shaft disposed close to 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.

10. The air controlling system of claim 3, wherein the rear console door includes a rotary shaft disposed close to 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.
