The filter frame 12 is allowed to come in and out of the filter holder mounting holes 2 and 3, which is formed in a substantially square shape similar to the filter 13 mounted in the frame and has a corner on one side of its upper part. A substantially square notch 14 is formed, and slide rails 15 and 16 are provided on the outer peripheral surface of the filter frame 12 that sandwiches the notch 14.

The slide rails 15 and 16 are formed in a substantially T-shaped cross section, and are slidably inserted between the locking claws 11 and 11 of the filter holders 4 and 5.

On the other hand, a rib 18 having a concave groove 17 is provided in the lower portion of the duct 1, and the lower end portion of the filter frame 12 can be inserted into the concave groove 17.

FIG. 5 shows another embodiment of the present invention, in which the same reference numerals are used for the components corresponding to those of the above-mentioned embodiment. In this embodiment, a filter holder 5 is attached to the side wall of the duct 1 facing the above-mentioned side wall, and a filter frame 12 is housed in the duct 1 in the left-right direction opposite to the above, and the filter is attached to the duct 1 as shown in the figure. The feature is that it can be detached from above and to the right.

The air-conditioning filter mounting structure thus configured requires the production of a filter frame 12 having slide rails 15 and 16 on two sides and two filter holders 4 and 5. In addition to the above, the filter holder mounting holes 2 and 3 are provided on the peripheral surface of the duct 1 at predetermined positions according to the specified filter attachment / detachment direction and air conditioner layout specifications. In the embodiment, the filter holder mounting holes 2 and 3 are provided at two locations on the upper peripheral surface and the side surface of the duct 1.

Next, when mounting the filter on the duct 1, for example, the filter holder 5 is inserted into one of the filter holder mounting holes 3 and is fixed to the side surface of the duct 1 via the screw 9. In this way, the locking claws 11, 11 of the filter holder 5 project into the side wall of the duct 1, and a plurality of sets of them are arranged vertically. After that, one slide rail 15 of the filter frame 12 is inserted into the locking claws 11, 11 of the filter holder 4 to hold the filter frame 12 in the locking claws 11, 11.

Then, the filter frame 12 and the filter holder 4 are inserted together into the filter holder mounting hole 2 while maintaining the locked state of the locking claws 11, 11 and the slide rail 15, and at that time, 16 is inserted into the locking claws 11, 11 of the filter holder 5 thus arranged from above.

After the filter holder 4 is housed in the filter holder mounting hole 2 and the slide rail 16 is inserted into all the locking claws 11, 11, the lower end of the filter frame 12 is pushed into the concave groove 17 to support that portion. By the way, the screw 9 is screwed into the screw hole 10 through the screw hole 7, the filter holder 4 is fixed to the upper surface of the duct 1, and the mounting of the filter is completed.

In the filter frame 12 thus mounted, the slide rail 15 engages with the locking claw 11 of the filter holder 4, the slide rail 16 engages with the locking claw 11 of the filter holder 5, and the lower end portion Since the groove is sandwiched by the elasticity of the concave groove 17, play due to the traveling vibration of the vehicle is absorbed, and the generation of abnormal noise is prevented. Further, since the filter holder mounting holes 2 and 3 are closed by the filter holders 4 and 5, air does not leak from the parts during the air conditioning operation.

For example, when the filter is taken out above the duct 1, the screw 9 is removed, the filter holder 4 is held, and this is pulled up. In this way, the filter frame 12 is pulled up together with the filter holder 4, the slide rail 16 thereof is moved along the locking claws 11 of the filter holder 5, and is pulled out from the filter holder mounting hole 2.

After that, if the slide rail 15 is moved along the locking claws 11 and the filter frame 12 is pulled out from the filter holder 4, the filter 13 can be cleaned. When mounting the filter 13 in the duct 1 after cleaning, insert the slide rail 15 into the locking claws 11 and 11 in the same manner as described above, and insert the slide rail 15 into the filter holder mounting hole 2 while maintaining the locked state. When the slide rail 16 is inserted into the locking claws 11 and 11, and the lower end of the filter frame 12 is pushed into the groove 17, the screw 9 is screwed into the screw holes 7 and 10, and the filter holder 4 is inserted. Should be fixed.

On the other hand, when the filter is taken out to the side of the duct 1, the screw 9 is removed, the filter holder 5 is held, and this is pulled to the side of the duct 1. In this way, the filter frame 12 moves together with the filter holder 5, and the slide rail 15 moves along the locking claws 11 of the filter holder 4 and is pulled out from the filter holder mounting hole 3.

After that, the slide rail 16 is moved along the locking claws 11 and the filter frame 12 is pulled out from the filter holder 5, so that the filter 13 can be cleaned. When mounting the filter 13 in the duct 1 after cleaning, insert the slide rail 16 into the locking claws 11 and 11 and insert them into the filter holder mounting hole 3 while maintaining the locked state appropriately. At that time, the slide rail 15 is inserted into the locking claws 11 and 11, the lower end of the filter frame 12 is pushed in from the side of the groove 17, and the screw 9 is screwed into the screw holes 7 and 10, and the filter holder 5 is inserted. Should be fixed.

As described above, according to the present invention, since the filter can be attached / detached from above or to the side of the duct 1, the optimum attachment / detachment direction of the filter can be selected according to the arrangement condition of the air conditioner, which is convenient for the maintenance of the filter. Since the filter can be applied to an air conditioner that is attached or detached from above or from the side, its application range can be expanded.
