As a result, the DEF air outlet 2 is closed and the front FOOT air outlet 3 and the rear FOOT air outlet 4 are opened as in the above-described auto control.
[0052]
Further, the first FACE door body 52 of the first FACE opening / closing door is stopped at a predetermined stop position (position in FIG. 7) further rotationally displaced in the left rotation direction in FIG. 5 by the automatic control described above. At this time, the seal packings 53 and 54 attached to the first FACE door body 52 come into contact with the rib portions 34 and 35 in a state where the seal packings 53 and 54 are greatly bent as compared with the time of the automatic control described above, so that the center FACE ventilation path 25 The closed (seal) state is maintained and the center FACE outlet 5 is closed.
[0053]
Further, like the first FACE door body 52, the second FACE door body 62 of the second FACE opening / closing door has a predetermined stop position (position in FIG. 8) further rotationally displaced in the left rotation direction in FIG. ). At this time, the seal packings 63 and 64 attached to the second FACE door main body 62 come into contact with the rib portions 36 and 37, thereby closing (sealing) the side FACE ventilation path 26 and closing the side FACE outlet 6. (Two-stage seal state).
[0054]
Therefore, the warm air heated by the heater core 15 according to the opening degree of the air mix doors 16 and 17 flows only into the FOOT ventilation path 22, so that the front FOOT blowout port 3 and the rear FOOT blowout port 4 Comfortable heating is achieved by mainly blowing hot air intensively toward the feet.
[0055]
Even if the outlet mode is switched to the F / D mode or the DEF mode by the manual control of the vehicle occupant, the center FACE ventilation path 25 and the side FACE ventilation path 26 are used in the same manner as the FOOT mode by the manual control. Wind leakage may be prevented.
[0056]
