The mounting members 4d and 4e are used for the scroll chamber 12
To form a bell mouth-shaped suction port 19 of
The scroll chamber 12 is attached to the spiral portion 41 formed in the half cases 4b and 4c from the center side in the vehicle width direction (see FIGS. 8 and 9) to form the scroll chamber 12 together with the spiral portions 41 of the half cases 4b and 4c. It is a thing. A partition 42 defining the inside / outside air switching box 11 and the air passage P is integrally formed on the mounting members 4d, 4e, but the partition 42 may be provided on the partition member 4a.

The half-split cases 4b and 4c are symmetrically formed with the half-split case 4c on the driver's side and the half-split case 4b on the passenger's side, with the mounting members 4e and 4d attached (FIG. 8, FIG. 9)) and the partition member 4a is sandwiched between them, and they are assembled to each other by fastening means such as a clamp (not shown). The inside / outside air switching box 11, the driver-side scroll chamber 12, the passenger-side scroll chamber 12, and the driver-side air duct The unit case 4 in which P (PL) and the passenger's seat side air duct P (PR) are formed is completed. 8 and 9, reference numeral 43 is a door case holding portion of the inside / outside air switching door device 16, and reference numeral 44
Is an evaporator holding portion, reference numeral 45 is a door case holding portion of the air mix door device 25, reference numeral 46 is a heater core holding portion, and reference numeral 47 is a door case holding portion of the mode switching door device 27.

According to the vehicle air conditioner 1 and the air blower 2 as described above, first of all, the two scroll chambers 12,
In the structure in which the suction ports 19 of 19 are arranged to face each other,
The partition plate 2 is provided between the suction ports 19 and 19 arranged to face each other.
Since there is 1, there is no interference between both centrifugal multi-blade fans 13, 13. That is, as shown in FIG. 12, in a blower device that does not include a partition plate, both centrifugal multi-blade fans 13, 13 may interfere with each other to cause backflow, but according to the blower device 2 of the present embodiment, such a case occurs. Problems due to interference between the centrifugal multi-blade fans 13, 13 do not occur.

Secondly, since the drive motors M, M for the centrifugal multi-blade fans 13, 13 are provided outside the inside / outside air switching box 11, the inside / outside air switching box is provided as in the prior art disclosed in Japanese Patent Laid-Open No. 61-18921. Unlike the case where a fan drive motor is installed in
The internal space of the inside / outside air switching box 11 can be set wide.

Thirdly, by providing the inside / outside air switching box 11 at the center of the vehicle in the vehicle width direction and setting the winding shaft of the scroll chamber along the vehicle width direction, the blower device 2 is placed in the vehicle width direction center line of the vehicle. Since the vehicle air-conditioning system 1 is configured symmetrically with respect to the vehicle, the right-hand steering wheel and the left-hand steering wheel can be shared.
In addition, since the opening area of the inside air intake port 14 of the inside air / outside air switching box 11 is symmetrical with respect to the center line in the vehicle width direction, the inside / outside air switching box 1 as in the conventional vehicle air conditioner 100 shown in FIG.
Unlike the case where 01 is offset from the center of the vehicle in the vehicle width direction, the conditioned air blown from the temperature control device 3 into the vehicle compartment returns to the center of the vehicle width direction as shown in FIG. Therefore, it is possible to provide a suitable vehicle interior space.

Fourthly, the temperature control device 3 is provided with a partition plate 36 for partitioning the air flow path P of the temperature control device 3 into the driver seat side air flow path PL and the passenger seat side air flow path PR, and the air supply device 2 is operated. Since the scroll chamber 12 on the seat side is communicated with the air duct PL on the driver side and the scroll chamber 12 on the passenger side is communicated with the air duct PR on the passenger side, the air volumes of the driver side air duct PL and the passenger side air duct PR are Each can be controlled independently.

Fifth, the integrated unit case 4 of the air blower 2 and the temperature controller 3 is provided with a single plate member 4a and a mounting member 4d for forming bellmouth-shaped suction ports 19, 19.
4E and the pair of half-split cases 4b and 4c are included in the five parts, so that it is possible to provide the vehicle air conditioner 1 with a small number of parts and high assembly efficiency.

In the above embodiment, the gap between the pair of scroll chambers 12, 12 facing each other is shortened to reduce the size in the vehicle width direction, but the opening areas of the inside air intake port 14 and the outside air intake port 15 are widened. For the purpose of taking in, the inside / outside air switching door device 16 is arranged across the scroll chambers 12, 12 so as to cover the pair of scroll chambers 12, 12, which are arranged to face each other. When there is a margin, the inside / outside air switching device 16 may be arranged between the pair of scroll chambers 12 facing each other.

In the above-described embodiment, the inside / outside air switching door device 16 is a slide type, but, for example, as shown in FIG. 11, it is a swinging type that rotates over the inside air intake 51 and the outside air intake 52. It may be the door 53. Further, the air mix door device 25 and the mode switching door device 27 may be swingable.

Further, in the above-described embodiment, an example in which the blower device 2 and the warm air device 3 are configured as an integrated unit is shown, but in the present invention, the blower device 2 and the warm air device 3 are separate units. Alternatively, the inside / outside air switching box 11 may be provided separately.
