DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of an air conditioner-mounted air cleaner according to the present invention will be described with reference to the accompanying drawings.
[0019]
FIG. 1 is a cross-sectional view showing an air purifier mounting structure according to the present embodiment. The structure for detachably attaching the dust collecting unit 7 to the fixed frame 5 is different from the conventional air purifier shown in FIGS. The same reference numerals are assigned and detailed description thereof is omitted.
[0020]
In FIG. 1, the mounting frame 5 on the indoor unit side is provided with a similar mounting portion 20 except for the locking portion 22 shown in FIG. The mounting portion 20 is formed integrally with the fixed frame 5 so as to form a cross section in which the rib 43, the rib 44, and the rib 45 are continuously closed inside the outer rib 42. Among these, the rib 43 and the rib 44 form the guide groove 24. Plate-shaped portions 32 formed on both side surfaces of the main body case 14 of the dust collecting unit 7 are inserted into the guide grooves 24. A cylindrical guide portion 32 a having a diameter substantially equal to the width of the guide groove 24 is formed at one end of the plate-like portion 32. A locking boss 46 having a claw 47 is formed on the side surface of the main body case 14 of the dust collection unit 7.
[0021]
Next, the latching part 48 which the latching boss | hub 46 of such a dust collection unit 7 latches is demonstrated.
[0022]
The locking portion 48 is composed of the rib 45 described above and an elastic portion 49 provided on the fixed frame 5 so as to be spaced from the rib 45 by a distance that is somewhat smaller than the width of the locking boss 46. . A claw 50 that engages with the claw 47 of the locking boss 46 is formed on the rib 45 as a hook portion. In this embodiment, the elastic portion 49 is formed of an elastic piece integrally formed with the fixed frame 5, and this elastic piece is opposed to the rib 45 so as to be bent from the fixed frame 5 with a loose curvature for easy attachment / detachment. Standing up to. A stopper portion 52 integral with the fixed frame 5 is provided below the elastic portion 49. When the elastic portion 49 is bent, the tip portion of the stopper portion 52 comes into contact with the tip portion, so that it is not further elastically deformed and can be prevented from being damaged. As shown in FIG. 1, the gap A between the distal end of the elastic portion 49 and the distal end of the stopper portion 52 is considerably smaller than the interval B between the locking bosses 46. It is not inserted into the gap between the elastic part 49 and the stopper part 52.
[0023]
When the dust collecting unit 7 is attached to the fixed frame 5, the claws 47 and 50 engage with each other, and the elastic portion 49 bends to press the locking boss 46 toward the rib 45 with its elastic force. It is held so that the engaged state is not released. Here, in FIG. 1, the dust collection unit 7 is shown in a posture when the indoor unit is installed. In this installation posture, the rib 45 of the locking portion 48 is on the upper side, and the elastic portion 49 is on the lower side. Accordingly, the weight of the dust collecting unit is applied to the elastic portion 49 and does not act on the rib 45 of the locking portion.
[0024]
On the other hand, in the product shipping and distribution process, the indoor unit is packed and stored or transported. In that case, the posture of the dust collecting unit 7 is exactly opposite to that of the above-described installation, and the direction of gravity is the direction indicated by the arrow. Accordingly, the weight of the dust collection unit 7 is applied to the highly rigid rib 45 and does not act on the elastic portion 49. For this reason, it is possible to prevent deformation of the elastic portion 49 that is easily deformed. Moreover, since the rib 45 and the elastic part 49 are hooked by the claws 47 and 50, they will not come off even if they are subjected to vibration during transportation.
[0025]
【The invention's effect】
As apparent from the above description, according to the present invention, it is possible to prevent deformation of the locking portion that fixes the dust collection unit to the fixed frame, and to firmly attach the dust collection unit.
