Abstract:
1. A vehicular air conditioner comprising: a cooling unit for cooling air and supplying the cooled air; a heating unit for heating air and supplying the heated air; an air mixing door for mixing the cooled air and the heated air with each other at a given mixing ratio in a mixer; a plurality of outlet ports for discharging mixed air produced by said air mixing door through a discharge outlet door selectively into respective predetermined regions in a vehicle; a cooled air passage for leading said cooled air from said cooling unit to said mixer; a heated air passage for leading heated air, which is produced by heating the cooled air from said cooling unit with said heating unit, to said mixer; seal members mounted respectively on surfaces, which face said cooled air passage and said heated air passage, respectively, of said air mixing door, which is disposed between said cooled air passage and said heated air passage, said seal members being configured to close said cooled air passage and said heated air passage to block fluid communication therebetween when said air mixing door is opened and closed; a guide structure disposed on the surface, which faces said mixer, of said air mixing door, for mixing said cooled air and said heated air, said guide structure having a first wall for changing the direction of flow of said cooled air supplied from said cooled air passage and a second wall for changing the direction of flow of said heated air supplied from said heated air passage; and a pair of flow guide walls for changing the direction of flow of the cooled air, the pair of flow guide walls being disposed between said first and second walls and projecting from the surface, which faces said mixer, of said air mixing door by a distance which is smaller than the height of said first and second walls and smaller than the thickness of said seal member disposed on the surface, which faces said mixer, of said air mixing door, wherein said guide structure includes a third wall interconnecting said first wall and said second wall, and each of said pair of guide walls is provided at each longitudinal end of said air mixing door and connected to said third wall.
