  The vehicle air conditioner 10 according to the first embodiment of the present invention is basically configured as described above. Next, the air blower 14 and the actuator 22 are assembled to the air conditioning case 12. explain.

  First, as shown in FIG. 2, the blower 14 is gripped so as to be straight with respect to the mounting hole 36 of the blower mounting portion 34 in the air conditioning case 12, and the fan 40 is moved from the opening on the first divided case 26 side. Insert it. Then, the blower 14 is fixed to the blower mounting portion 34 in a state where the motor 42 of the blower 14 protrudes toward the space 44 (arrow A1 direction).

  Next, the holder 24 assembled in advance of the actuator 22 is brought into contact with the side wall of the first divided case 26 and fixed through a plurality of bolts 60, whereby the vehicle air conditioner as shown in FIG. 1A. The actuator 22 is assembled so as to overlap with the motor 42 of the blower 14 through the space 44 when viewed from the width direction 10.

  Next, the operation of the vehicle air conditioner 10 in which the blower 14 and the actuator 22 are assembled to the air conditioning case 12 as described above will be described.

  First, on the basis of a control signal from a controller (not shown), the fan 42 is rotated by driving the motor 42 of the blower 14 and the occupant operates an operation switch disposed in the passenger compartment. Then, a control signal is output from the controller to the actuator 22, and the first switching damper 48 or the via the actuator link (not shown), the intermediate links 58a and 58b, and the damper links 64a and 64b under the driving action of the actuator 22.

The temperature is adjusted to a desired temperature, and the air is blown into the vehicle compartment through the vent vent port 30 and the defroster vent port 32 that are opened.

  As described above, in the first embodiment, the actuator 22 for driving the damper mechanism 20 in the vehicle air conditioner 10 is viewed from the width direction of the vehicle air conditioner 10 (evaporator 16), and the air conditioning case. 12, the installation area of the side wall of the air-conditioning case 12 provided with the actuator according to the prior art is reduced by being arranged so as to overlap with the axis on the motor 42 side (arrow A1 direction) of the blower 14. Can do. As a result, the vehicle air conditioner 10 can be further reduced in size by effectively utilizing the dead space existing on the rear end side (arrow A1 direction) of the motor 42 on the axis of the blower 14 in the air conditioning case 12. Can do.

  Further, when the actuator 22 is arranged, it is not limited to the position of the motor 42 in the blower 14 and can be arranged at an optimal place considering only the balance with the positions of the first and second switching dampers 48 and 52. The degree of design freedom can be increased.

  Furthermore, the actuator 22 is disposed in the holder 24 so as to overlap with the shaft center 42a of the motor 42 in the blower 14, and the space overlapping with the motor 42 is secured sufficiently large, thereby further effectively utilizing the space. Can do.

  Furthermore, by separating the air conditioning case 12 and the holder 24 from each other, the actuator 22 is arranged on the rear end side (arrow A1 direction) of the motor 42 with a simple configuration without complicating the shape of the air conditioning case 12. Can be suitably arranged.

  Furthermore, at least a part of the actuator 22 overlaps with a region S between the first and second virtual lines L1 and L2 extending from the widthwise end of the evaporator 16 housed in the air conditioning case 12.

  Furthermore, the intermediate links 58a and 58b for driving the first and second switching dampers 48 and 52 are rotatably supported with respect to the holder 24, so that it has conventionally been necessary to support the intermediate links. Since the installation area on the side wall of the air conditioning case 12 can be reduced, the space required for the installation of the intermediate links 58a and 58b can be effectively utilized, and accordingly, the vehicle air conditioner can be downsized. it can.

  Furthermore, after assembling the actuator 22 to the holder 24 in advance, the holder 24 is assembled to the side wall of the air-conditioning case 12, so that it is unnecessary to install the actuator 22 between the holder 24 and the motor 42 of the blower 14. It is not necessary to secure a space, and the actuator 22 can be disposed closer to the motor 42, so that the space on the rear end side (in the direction of the arrow A1) of the motor 42 can be used more effectively. it can.

  Further, the present invention is not limited to the case where the actuator 22 is provided on the surface 24a opposite to the first divided case 26 side with respect to the holder 24. For example, the actuator 22 of the vehicle air conditioner 70 shown in FIGS. 3A and 3B is used. Thus, the actuator 22 may be provided on the surface 24b of the holder 72 on the first split case 26 side (arrow A2 direction). In this case, the rotating shaft 62 of the actuator 22 protrudes through a hole (not shown) to a surface 24a which is the opposite side (arrow A1 direction) to the first split case 26 side.

  Thus, in the holder 72 facing the space 44 of the first divided case 26, the actuator 22 is provided in the region S on the blower 14 side (in the direction of arrow A2), thereby comparing with the vehicle air conditioner 10 described above. Further, the space portion 44 can be effectively used, and the shape of the holder 72 can be simplified.

The opening end 84 is fixed to the side surface of the blower mounting portion 34, and is spaced apart from the opening end 84 by a predetermined distance. The actuator 22 may be attached to the planar attachment portion 86.

  Further, like the holder 92 in the vehicle air conditioner 90 shown in FIG. 4B, the outer edge portion 94 is fixed to the side wall of the first divided case 26, and the storage portion 96 that is recessed in a U-shaped cross section at the substantially central portion. Alternatively, the actuator 22 may be provided therein.

  With such a configuration, the holders 82 and 92 can be arranged in the region S, and even when the actuator 22 is provided on the surface opposite to the motor 42 (in the direction of the arrow A1), It is possible to arrange them in an overlapping manner. As a result, the actuator 22 can be attached and detached while the holders 82 and 92 are attached to the air conditioning case 12, and the assembling property and the maintenance property can be improved.

  Furthermore, since the holders 82 and 92 themselves overlap with the region S, the actuator 22 can be reliably overlapped with the region S even if the actuator 22 is fixed to the surface opposite to the motor 42.

  Furthermore, a two-layered holder 102 may be employed as in the vehicle air conditioner 100 shown in FIGS. 5A and 5B. The holder 102 includes a planar base portion 104 that abuts against the side wall of the first divided case 26, and a mounting portion 106 that is provided in parallel with the base portion 104 at a predetermined interval. The portion 104 and the mounting portion 106 are fixed to the first divided case 26 via a plurality of leg portions 108 provided at corners.

It is done. When the actuator 22 is provided on the mounting portion 106, as shown in FIG. 5A, the actuator 22 is provided on the surface opposite to the surface facing the base portion 104, while the actuator 22 is provided on the base portion 104. The first split case 26 side (in the direction of arrow A2), which is the opposite side of the surface facing the mounting portion 106, is provided.

  With such a configuration, the link mechanism such as the intermediate links 58a and 58b can be protected between the attachment portion 106 and the base portion 104, and the intermediate links 58a and 58b and the like can be protected from the attachment portion 106. By supporting each of the base portion 104 so as to be freely rotatable, it is possible to perform a more stable rotation operation.

  The vehicle air conditioners 10, 70, 80, 90, and 100 described above are vehicle air conditioners that have a defroster air vent 32 and are used for the front seat of a vehicle, but have the defroster air vent 32. You may make it apply said structure to the vehicle air conditioner used for the back seats of the vehicle which is not.

  Furthermore, the actuator 22 described above is used for driving the first and second switching dampers 48 and 52 for mode switching for switching the air blowing mode, but is not particularly limited thereto. It may be an actuator used for switching between inside and outside air to switch between inside air and outside air, or may be an actuator for driving an air mix damper for mixing cold air and hot air.
