The air is selectively supplied to the defroster opening 90, the vent opening 48, and the heat opening 78 that can blow air to the seat and the intermediate seat.

  On the other hand, as shown in FIGS. 1 and 2, the second blower 22 is connected to the lower portion of the casing 12 at a position on the upstream side of the evaporator 18 and communicates with the first rear passage 114. The first rear passage 114 is separated from the first front passage 32 via the first separation wall 116.

  The second blower 22 includes a second blower fan 118 that takes in air (inside air) in the vehicle interior and supplies the taken air into the casing 12, and the second blower fan 118 is housed in the third blower case 120. Has been. The second blower fan 118 is rotationally controlled by a fan motor (not shown) that is driven under an energization action with respect to a rotational drive source (not shown), as in the first blower fan.

  A second rear passage 122 to which air that has passed through the second cooling portion 36 of the evaporator 18 is supplied is formed on the downstream side of the first rear passage 114. The second rear passage 122 is separated from the second front passage 38 by the second separation wall 124. Is done.

  Here, the second front passage 38 and the second rear passage 122 are separated on the first and second divided case portions 26 and 28 sides around the divided plate 30 provided in the center of the casing 12.

  The vehicle air conditioner 10 according to the embodiment of the present invention is basically configured as described above, and its operation and effects will be described. Here, the operation in the case where the heat differential mode in which air is blown to the vicinity of the passenger's feet and in the vicinity of the front window in the passenger compartment is selected will be described.

  First, when the vehicle air conditioner 10 is started, the first blower fan of the first blower 16 rotates under an energization action with respect to a rotational drive source (not shown), and the air (outside air or inside air) taken in through the duct 110 is connected. At the same time as being supplied to the first front passage 32 of the casing 12 through the duct 14, air (inside air) taken in by the second blower fan 118 of the second blower 22 rotating under an energizing action with respect to a rotation drive source (not shown). Is supplied to the first rear passage 114. Here, the air supplied into the casing 12 by the first blower fan will be described as the first air, and the air supplied into the casing 12 by the second blower fan 118 will be described as the second air.

  The first air and the second air supplied into the casing 12 are cooled by passing through the first and second cooling parts 34 and 36 of the evaporator 18, respectively, and are provided with an air mix damper 44 as cold air. 2 flows to the front passage 38 and the second rear passage 122, respectively.

  The air mix damper 44 and the cool vent damper 46 block the communication between the second front passage 38 and the third front passage 40, and the vent damper 50 rotates to close the vent opening 48. Thus, after the first air of warm air that has passed through the heater core 20 from the second front passage 38 through the fourth front passage 42 is mixed in the third front passage 40, the pair of sixth front inner passages 76, 6 are respectively supplied to the front outer passages 64. The first air is blown from the sixth front inner passage 76 through the heat opening 78 and a heat blower opening (not shown) to the vicinity of the feet of the occupant in the front seat in the vehicle interior. In other words, the sixth front inner passage 76 functions as a heat passage for sending the heated first air to the vicinity of the feet of the occupant.

  On the other hand, the first air supplied to the sixth front outer passage 64 rotates the defroster damper 92 to open the defroster opening 90, thereby opening the front air in the vehicle through a duct (not shown) connected to the defroster opening 90. Supplied near the window. In this case, by rotating the sub defroster dampers 60a and 60b simultaneously, the fifth front passage 56 and the sixth front outer passage 64 are communicated, and the sixth front outer passage 64 is connected via the third front passage 40. In addition to the supplied first air, the first air that has passed through the heater core 20 can be supplied upward through the sixth front outer passage 64 and supplied from the defroster opening 90 into the vehicle interior. . That is, the sixth front outer passage 64 functions as a defroster passage for sending the heated first air to the vicinity of the front window of the vehicle.

  As described above, in the present embodiment, the first and second passages are divided on both sides of the first and second divided case portions 26 and 28 divided by the divided plate 30 with the divided plate 30 in between. By providing the members 62a and 62b, a pair of sixth front outer passages 64 are formed between the divided walls 72a and 72b and the first and second divided case portions 26 and 28, and the divided walls 72a and 72b A pair of sixth front inner passages 76 are formed between the divided plates 30. As a result, since the sixth front outer passage 64 and the sixth front inner passage 76 can be easily and reliably divided inside the casing 12, the first and second passage dividing members 62a and 62b are simply provided. With this structure, the passage through which the air flows can be reliably divided into four inside the casing 12, and the first air can be obtained through the four separated sixth front inner passages 76 and sixth front outer passages 64. It is possible to supply the air blowing port with a desired air blowing amount and air blowing temperature.

  In addition, the productivity can be improved and the manufacturing cost can be reduced as compared with the conventional vehicle air conditioner having a complicatedly divided passage in the casing.

  Furthermore, by providing the first and second passage dividing members 62a and 62b, the sixth front inner passage 76 and the sixth front outer passage 64 can be arranged in the casing 12 so as to be orthogonal to each other. And the 1st and 2nd channel | path division | segmentation member 62a, 62b can be reliably assembled | attached by the simple operation | work of clamping between the division | segmentation plate 30 and the inner wall face of the 1st and 2nd division | segmentation case parts 26 and 28. FIG. it can.

  Furthermore, the first and second passage dividing members 62a and 62b have their blocking walls 74a and 74b guided along the guide walls 88a and 88b toward the dividing plate 30, and the blocking walls 74a and 74b are fitted. The pair of concave portions 82a and 82b are inserted into the holes 84 and engaged with the fitting portions 86a and 86b, respectively, and are assembled to the divided plate 30 in a state of being accurately positioned.

  Furthermore, when the first and second passage dividing members 62a and 62b, the sub defroster dampers 60a and 60b, and the dividing plate 30 are assembled to the casing 12, the rotary shafts 66 of the sub defroster dampers 60a and 60b are previously set in the first. And the second passage dividing members 62a and 62b are inserted into the shaft support grooves 80 and the through holes 70 of the dividing plate 30, so that both end portions of the rotating shaft 66 are divided into the dividing plate 30, the first and first plates. Since it is supported by the two-passage dividing members 62a and 62b, the shaft support groove 80 of the first and second passage-dividing members 62a and 62b and the dividing plate 30 are easily unitized and assembled in the casing 12 in advance. Assembly work can be performed.

  In addition, the vehicle air conditioner according to the present invention is not limited to the above-described embodiment, and it is needless to say that various configurations can be adopted without departing from the gist of the present invention.
