An air conditioner for an automobile includes a foot door (11) and a mixing area. The foot door has a partition wall, and is movable at least between an advanced position where the partition wall reaches a state of blocking an air flow from a merging area to the downstream side in an air passage, and a retreated position where the partition wall retreats from the advanced position in the air passage. The mixing area is provided in the air passage while the partition wall is located in the advanced position, and is designed to cause the air flowing from a cold air passage and the air flowing from a hot air passage into the merging area to mix up more by using the partition wall to block the air flowing from the merging area to the downstream side. Thus, the air conditioner is designed to cause the air to flow into the discharge passage systems via the mixing area.

1. An air conditioner for an automobile, the air conditioner comprising: a case having an air passage formed therein, the air passage including a cold air passage having an evaporator, a hot air passage having a heater core, a plurality of discharge passage systems communicating with outlets and including a first discharge passage and a second discharge passage, and a merging area in which the cold air passage and the hot air passage merge, wherein air flows into each of the outlets from the merging area;a door disposed in the merging area and including a partition wall configured to be movable between an advanced position and a retreated position where the partition wall retreats from the advanced position; anda mixing area formed by the partition wall of the door at an area where the cold air passage meets the hot air passage,wherein the outlets include a vent outlet and a foot outlet provided downstream of the merging area,wherein the door partially blocks air flowing from the merging area to the first discharge passage to mix cold air from the cold air passage and hot air from the hot air passage in the mixing area when the door is in the advanced position, and guides air from the mixing area to the first discharge passage along the partition wall through detour passages when the door is in the advanced position, the detour passages being configured to communicate with the vent outlet and the foot outlet,wherein the door closes air flow to the second discharge passage and does not block air flow to the first discharge passage when the door is in the retreated position,wherein the door includes a pair of substantially sector-shaped sidewalls which are parallel with each other and a stem acting as a hinge of the sidewalls, and each of the sector-shaped sidewalls has edges which extend in a radial direction from the stem,wherein the partition wall is connected to outer circumferential edges of the sidewalls,wherein the door is formed as a rotary door that rotates about the stem, and the door is rotatably and pivotally supported by the case,wherein the door is configured such that a distance from the stem to an end portion of the partition wall in a circumferential direction on a rear side of the door is shorter than a distance from the stem to the end portion of the partition wall in the circumferential direction on a front side of the door, the front side of the door being in front of the rear side of the door in an advancement direction of the door,wherein a rotational angle of the door between the advanced position and the retreated position is larger than a central angle between the edges of each of the sector-shaped sidewalls, andwherein the case and the door are configured such that air is blown from both the vent outlet and the foot outlet through the detour passages when blowing the air from both the vent outlet and the foot outlet simultaneously. 2. The air conditioner of claim 1, wherein the outlets further include a defrost outlet. 3. The air conditioner of claim 1, wherein the vent outlet is a center vent outlet, and the outlets further include a defrost outlet and a side vent outlet, wherein the first discharge passage communicates with the center vent outlet and the side vent outlet of the air conditioner, andwherein a center vent door is disposed at the center vent outlet and is adjustable to close the center vent outlet, a defrost door is disposed at the defrost outlet and is adjustable to close the defrost outlet. 4. The air conditioner of claim 3, wherein a first air mixing door is disposed in the cold air passage, wherein a second air mixing door is disposed in the hot air passage, andwherein the first air mixing door and the second air mixing door are adjustable to control a distribution of air between the cold air passage and the hot air passage. 5. The air conditioner of claim 4, further comprising a blower communicated with the case for blowing air through the air passage, wherein the evaporator is disposed downstream of the blower, the heater core is disposed downstream of the evaporator, and the door is disposed downstream of the evaporator and the heater core. 6. The air conditioner of claim 5, wherein the first air mixing door is disposed between the evaporator and the door, and the second air mixing door is disposed between the evaporator and the heater core. 7. The air conditioner of claim 4, wherein the first air mixing door is disposed between the evaporator and the door, and the second air mixing door is disposed between the evaporator and the heater core. 8. The air conditioner of claim 1, wherein the door includes: a seal member provided on an end portion of the door in a circumferential direction on a rear side of the door and a first seal surface which contacts the case in the retreated position; anda seal member provided on the end portion of the door in the circumferential direction on a front side of the door and a second seal surface which contacts the case in the advanced position,wherein the door is configured such that a distance between the first seal surface and the stem is shorter than a distance between the second seal surface and the stem, andwherein a breadth of the first seal surface is shorter than that of the second seal surface. 9. The air conditioner of claim 1, wherein the detour passages include a first detour passage which leads to the vent outlet and which is formed by a clearance between the partition wall and the case when the door is in the advanced position. 10. The air conditioner of claim 1, wherein the case and the door are configured such that air is blown from both the vent outlet and the foot outlet through the detour passages when the door is in the advanced position, and such that air cannot be blown from the foot outlet when the door is in the retreated position.
