## Abstract

An air conditioner for a vehicle, including: an air conditioning case including a rear console vent through which introduced air is discharged toward a rear console, a defrost vent through which air is discharged toward a front window, a face vent through which air is discharged in a direction of a front passenger, and a foot vent through which air is discharged in a foot direction of front and rear seats; a door unit including a defrost door, a face door, and a foot door that are rotatably disposed in the air conditioning case and adjust a degree of openness of each of the defrost vent, the face vent, and the foot vent; and a door driving unit that individually drives and controls the defrost door, the face door, and the foot door and establishes an air conditioning mode.

## Claims

### Claim 1

An air conditioner for a vehicle, comprising:
an air conditioning case comprising a rear console vent through which introduced air is discharged toward a rear console, a defrost vent through which air is discharged toward a front window, a face vent through which air is discharged in a direction of a front passenger, and a foot vent through which air is discharged in a foot direction of front and rear seats;
a door unit comprising a defrost door, a face door, and a foot door that are rotatably disposed in the air conditioning case and adjust a degree of openness of each of the defrost vent, the face vent, and the foot vent; and
a door driving unit that individually drives and controls the defrost door, the face door, and the foot door and establishes an air conditioning mode,
wherein an inlet of a rear console duct that interacts with the rear console vent is opened in normal times in each air conditioning mode so that air is able to be always discharged.

### Claim 2 (depends on 1)

The air conditioner for the vehicle of claim 1, wherein the inlet of the rear console duct is placed between a face duct inlet that interacts with the face vent and a foot duct inlet that interacts with the foot vent.

### Claim 3 (depends on 1)

The air conditioner for the vehicle of claim 1, further comprising a controller that controls the door driving unit to close all of the defrost door, the face door, and the foot door so that a rear console dedicated mode in which air is discharged only toward the rear console vent, is able to be established.

### Claim 4 (depends on 1)

The air conditioner for the vehicle of claim 1, wherein the air conditioning case further comprises a guide member that guides air to the rear console vent.

### Claim 5 (depends on 4)

The air conditioner for the vehicle of claim 4, wherein the guide member is disposed between the rear console duct inlet that interacts with the rear console vent and the face duct inlet that interacts with the face vent, and
the face door is configured in such a way that, when the face door makes a turning movement, a turning end of the face door selectively contacts the guide member.

### Claim 6 (depends on 5)

The air conditioner for the vehicle of claim 5, wherein the guide member comprises a contact protrusion that protrudes from the guide member and is provided at one side contacting the face door so as to maintain an airtight state with the face door and to restrict the turning movement of the face door.

### Claim 7 (depends on 5)

The air conditioner for the vehicle of claim 5, wherein the air conditioning case further comprises a guide protrusion that is provided at the rear console duct inlet facing the guide member and guides air to the rear console vent.
