  Next, details of the door opening fixing structure for fixing the CL / AP switching door 30 and the suction / diffusion switching door 31 to the AP opening position will be described with reference to FIGS. 3 and 4. FIG. 3 is an explanatory diagram showing an outline of the door opening fixing structure, and shows an appearance of the case 11 as viewed from the front. FIG. 4 is a plan view showing a configuration of a lock member 60 (corresponding to the common fixing member of the present invention) used for fixing the opening of the CL / AP switching door 30 and the suction / diffusion switching door 31.

  The CL / AP switching door 30 and the suction / diffusion switching door 31 are assembled so that one end of the rotating shafts 30a and 31a in the axial direction is exposed to the outside of the case 11, and D-shaped at the ends. D-shaped portions 30b and 31b (corresponding to the engaged portion of the present invention) which are convex portions having a cross section (corresponding to the predetermined shape of the present invention) are provided.

  FIG. 3 shows the state of the D-shaped portions 30b and 31b viewed from the outside of the case 11 when the CL / AP switching door 30 and the suction / diffusion switching door 31 are at the AP opening position. In the present embodiment, the CL / AP switching door 30 and the suction / diffusion switching door 31 are fixed at this opening position.

  The lock member 60 is a common fixing member that fixes the opening degree of the CL / AP switching door 30 and the suction / diffusion switching door 31, and as shown in FIG. 4, the CL / AP switching door 30 and the suction / diffusion switching door 31. The D-shaped portions 30b and 31b are respectively provided with engaging portions 61 and 62, and further, a rigid connecting portion 63 for connecting the engaging portions 61 and 62 is provided.

  The engaging portions 61 and 62 of the lock member 60 are formed with D-shaped recesses, so that when the CL / AP switching door 30 and the suction / diffusion switching door 31 are in the AP opening position, they are engaged. The parts 61 and 62 can be engaged with the D-shaped parts 30b and 31b. Further, latching claws 64, 65 are provided at the central part of the D-shaped linear portion edge of the engaging parts 61, 62, and the engaging parts 61, 62 and the D-shaped part are formed by the latching claws 64, 65. The engaged state with 30b, 31b is maintained.

  When the CL / AP switching door 30 and the suction / diffusion switching door 31 are in the AP opening position, the engaging portions 61 and 62 of the lock member 60 are aligned on the D-shaped portions 30b and 31b from the outside of the case 11. When pressed against each other, the engaging portions 61 and 62 and the D-shaped portion 30b31b are engaged, and the engaging portions 61 and 62 cannot rotate the rotating shaft portions 30a and 31a. 31b and the lock member 60 is fixed to the outside of the case 11 so that the D-shaped portions 30b and 31b are connected by the connecting portion 63.

  Thus, the rigidity between the engaging portions 61 and 62 of the lock member 60 engaged with the D-shaped portions 30b and 31b of the CL / AP switching door 30 and the suction / diffusion switching door 31 at the AP opening position is rigid. The two D-shaped portions 30b and 31b function as a counterpart fixing portion (fixing portion similar to that formed in the case 11 in the conventional structure) via the lock member 60. Thus, both the CL / AP switching door 30 and the suction / diffusion switching door 31 are fixed at the AP opening position.

  In the present embodiment, the lock member 60 is made of resin, and is manufactured by pouring a resin material into a molding die. Further, the distance between the centers of the engaging portions 61 and 62 of the lock member 60 is about 69.3 mm in the present embodiment.

  Next, the operation of the air cleaning device (control by the control device 40) will be described. When the switch of the air purifier is turned on by an occupant on the operation panel 45 provided in the passenger compartment, the blower 21 is activated and the passenger compartment air is sucked from the inlet 15.

  At this time, the rotation speed of the blower 21 (blower voltage applied to the blower motor) is controlled based on a detection signal from the smoke sensor 23. Specifically, when the value detected by the smoke sensor 23 is large, the rotational speed is controlled to be high.

  The vehicle interior air sucked from the suction port 15 flows through the U-shaped channel 56 and is cleaned by the dust filter 20. The purified air passes through the ventilation path partitioned by the CL / AP switching door 30 and the suction / diffusion switching door 31 and is blown out from the outlet 16 into the vehicle interior.

  However, when the intake mode of the air conditioner on the vehicle front side is the inside air circulation mode, that is, when the outside air inlet of the front air conditioning unit 70 is closed and the inside air inlet is opened, the pressure inside the vehicle compartment is high. In order to prevent this, the trunk exhaust door 32 is opened as shown by the dotted line in FIG.

  As described above, in the present embodiment, the engaging portions 61 and 62 that engage with the D-shaped portions 30b and 31b of the CL / AP switching door 30 and the suction / diffusion switching door 31 at the AP opening position are provided. By using the locking member 60 having a configuration in which the engaging portions 61 and 62 are connected by the rigid connecting portion 63 as a common fixing member, the D-shaped portions 30b and 31b of the two doors 30 and 31 are the locking members. The opening positions can be fixed to each other via 60, and there is no need to form a fixing portion such as a boss on the case 11 side as in the conventional door opening fixing structure. For this reason, when introducing the door opening fixing structure, it is not necessary to remodel the molding die of the case 11.

  In addition, since the two doors 30 and 31 are fixed by one locking member 60, the number of parts can be reduced as compared with the conventional door opening fixing structure in which individual locking members are provided for each door. It is also possible to improve workability (assembly performance) when the doors 30 and 31 are fixed using the lock member 60.

  Conventionally, the doors 30 and 31 are provided with D-shaped portions 30b and 31b similar to those of the present embodiment at the axial ends exposed to the outside of the case 11 of the rotary shaft portions 30a and 31a. Therefore, as in the present embodiment, these D-shaped portions 30b and 31b are engaged portions so that they engage with the D-shaped portions 30b and 31b using the conventional configuration. The opening degree of the doors 30 and 31 can be fixed only by newly configuring the lock member 60 including the portions 61 and 62.

  Further, by configuring the lock member 60 with resin, details such as the engaging portions 61 and 62 and the locking claws 64 and 65 can be accurately configured in accordance with the shapes of the D-shaped portions 30b and 31b.
