PROBLEM TO BE SOLVED: To provide a vehicular air conditioning unit that enables easy tuning of a temperature and wind distribution and can comfortably cool the head and warm feet of occupants comfortably.SOLUTION: A vehicular air conditioning unit includes: a cool air flow passage 11; a warm air flow passage 12; a mixing chamber 13 for mixing cool air and warm air; mixing means 30 disposed in the mixing chamber 13; and first and second blowout flow passages 14, 15 disposed downstream of the mixing chamber 13. The cool air flow passage 11 and the mixing chamber 13 are communicated with each other at a cool air opening 111, and the warm air flow passage 12 and the mixing chamber 13 are communicated with each other at a warm air opening 121. The mixing means 30 includes: a movable wall portion 31 for adjusting opening areas of the cool air opening 111 and the warm air opening 121; a warm air guiding flow passage 32 for guiding part of warm air to the first blowout flow passage 14; and a wall portion flow passage 311a formed on the movable wall portion 31 to ventilate a space between the cool air opening 111 and the warm air opening 121. The mixing means can be displaced between a cool air minimizing position and a warm air minimizing position.SELECTED DRAWING: Figure 1 |
