Abstract

Disclosed therein is an air conditioner for a vehicle. The air conditioner includes console air volume distribution means formed on a mode cam to control the degree of opening of a console door in order to vary distribution of air volume of a console vent by air discharge modes, thereby preventing an excessive discharge of air to a console vent (rear seat) by regulating the console vent to be opened less in a floor mode and a mixing mode, which are air discharge modes of a heating mode, than when the console vent is opened the greatest, preventing displeasure of a passenger who is seating on a rear seat, enhancing heating performance, and preventing the lack of air volume in a front seat.

First claim

What is claimed is:

1 . An air conditioner for a vehicle which includes:
an air-conditioning case which has a defrost vent, a face vent and floor vents to discharge air introduced through an air inflow port; a defrost door, a face door and a floor door which are respectively rotatably mounted through rotary shafts inside the air-conditioning case to adjust the degrees of opening of the each vents; and a mode cam which has at least one slot connected with the rotary shaft of at least one of the doors through connecting means to make the connecting means carry out a cam motion so as to individually adjust the degree of opening of the door connected to the slot while rotating at a predetermined angle according to air discharge modes, wherein the air-conditioning case comprises a console vent for discharging air toward the rear seat of the vehicle and a console door for adjusting the degree of opening of the console vent, and wherein the mode cam comprises console air volume distribution means which varies distribution of air volume of the console vent according to the air discharge modes in order to adjust the degree of opening of the console door.

2 . The air conditioner according to claim 1 , wherein the console air volume distribution means comprises a console slot which is formed on the mode cam and is connected with a rotary shaft of the console door through the auxiliary connecting means to make auxiliary connecting means carry out the cam motion, and
wherein the console slot comprises: a closing slot part for operating the auxiliary connecting means so that the console door closes the console vent; an opening slot part for operating the auxiliary connecting means so that the console door opens the console vent the greatest; and a middle slot part for operating the auxiliary connecting means so that the console door opens the console vent less than when the console vent is opened the greatest.

3 . The air conditioner according to claim 2 , wherein the air discharge modes comprise a face mode, a bi-level mode, a floor mode, a mixing mode and a defrost mode, and
wherein in the face mode and the bi-level mode, the console vent is opened the greatest through the opening slot part of the console slot, wherein in the floor mode and the mixing mode, the console vent is opened less than the greatest opening through the middle slot part of the console slot, and wherein in the defrost mode, the console vent is closed through the closing slot part of the console slot.

4 . The air conditioner according to claim 2 , wherein a plurality of the slots are individually formed at the edge of the mode cam, and
wherein the console slot is formed inward from the plurality of the slots in the mode cam.

5 . The air conditioner according to claim 2 , wherein the auxiliary connecting means comprises:
a console arm which is connected to the rotary shaft ( 161 ) of the console door in the outer surface of the air-conditioning case and has a groove of a predetermined length formed at an end portion thereof; and a console lever which is rotatably connected to the outer surface of the air-conditioning case, whose an end portion extends to one side based on a rotational center and is connected to the groove of the console arm by a pin and whose the other end portion extends to the other side and connected to the console slot of the mode cam by a pin, so that the auxiliary connecting means operates the console door through the console lever and the console arm which carry out the cam motion along the console slot when the mode cam rotates.

6 . The air conditioner according to claim 2 , wherein when the face door opens the face vent the greatest, the console door is connected to a position of the opening slot part of the console slot through the auxiliary connecting means to open the console vent the greatest, and
wherein when the face door closes the face vent, the console door is connected to a position of the rest of the opening slot part of the console slot through the auxiliary connecting means to close the console vent at a predetermined angle from the greatest opening.

7 . The air conditioner according to claim 2 , wherein the air discharge modes comprise a face mode, a bi-level mode, a floor mode, a mixing mode and a defrost mode, and
wherein the console slot is linked with the air discharge modes from the opening slot part to the middle slot part and the closing slot part to operate the console door.

8 . The air conditioner according to claim 7 , wherein the opening slot part, the middle slot part and the closing slot part of the console slot are arranged in such a way that the degree of opening of the console vent is gradually reduced while the air discharge mode is changed from the face mode to the bi-level mode, the floor mode, the mixing mode and the defrost mode.

9 . The air conditioner according to claim 8 , wherein the opening slot part, the middle slot part and the closing slot part of the console slot are formed in the clockwise direction, and are formed in such a way as to have different radiuses from the rotational center of the mode cam.

10 . The air conditioner according to claim 9 , wherein the opening slot part, the middle slot part and the closing slot part are formed in such a way that the radiuses are gradually reduced from the rotational center of the mode cam.

11 . The air conditioner according to claim 1 , wherein the defrost door is independently controlled through separated operating means which is mounted on the outer surface of the air-conditioning case.

12 . The air conditioner according to claim 1 , wherein a floor channel for guiding the air inside the air-conditioning case to the floor vents is formed inside the air-conditioning case, the console vent is partitioned at the rear side of the floor channel, and an inlet of the console vent is formed in a partition wall, which partitions the console vent from the floor channel, and is formed above an inlet of the floor channel.
