Description

[Detailed Description of the Invention] The present invention relates to a mounting structure for vertical blades disposed at an air outlet of an air conditioner.

Conventionally, as shown in FIG. 6, this type of vertical blade 31 has an elastic claw piece 33 formed on its mounting shaft 32, which is forcefully fitted into a round hole 35 formed in a vertical blade mounting surface 34 of an air outlet. ,
It is attached by engagement between the elastic claw piece 33 and the round hole mouth edge 35a.

If such a mounting structure is adopted, if the elastic claw piece 33 is made large, it will be difficult to force fit into the round hole 35, but if the elastic claw piece 33 is made small, it will easily come off due to insufficient engagement with the round hole mouth edge 35a. There is a problem with the installation structure that the vertical blade 3
When rotating 1, there was a risk of it falling off.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, it is an object of the present invention to provide a mounting structure for vertical blades that is easy to assemble and does not easily fall off once assembled.

Hereinafter, a vertical blade mounting structure for an air conditioner according to an embodiment of the present invention will be described with reference to FIGS. 1 to 5.

In FIG. 1, reference numeral 1 denotes the main body of the indoor unit of the separate air conditioner, 2 the casing, 3 the casing top plate, 4 the casing rear plate, 5 the heat exchanger, 6 the cross-flow fan which is the blower, and 7 8 is an air suction port, 9 is a drain pan, 10 is a fan housing, and 11 is a hanging fitting for suspending the main body 1 from a ceiling C or a wall surface.

The air outlet 8 is rotatably provided with horizontal blades 12 for changing the wind direction in the vertical direction and vertical blades 13, 13 for changing the wind direction in the horizontal direction. .

The horizontal blades 12 are pivotally supported by both side walls 14 of the air outlet 8.

The vertical blades 13, 13, .

These vertical blades 13, 13, . . . are made into a set of four and connected by a connecting rod 16, so that the four blades face in the same direction at the same time.

A mounting shaft 17 is integrally protruded from the bottom of the vertical blade 13.

On the outer periphery of the flat end of the mounting shaft 17, l pairs of protrusions 18, 18 are integrally protruded at symmetrical positions in the same direction as the vertical blades 13.

Further, a flange portion 19 is integrally formed on the mounting shaft 17 above the upper surface of the projection 18.18 by the thickness of the outlet bottom surface 15.

The upper surface of the protrusion 18 is formed into an upwardly convex arcuate surface 20 to enable line contact and reduce frictional resistance.
(see figure).

Furthermore, a notched shaft hole 2 of the connecting rod 16 is provided at the rear of the vertical blade 13.
1 is formed with a shaft 22 to be fitted therein.

Protrusions 23, 23 are integrally formed near both sides of the notch 211 of the notched shaft hole 21 to regulate the rotation angle α30 to 40' of the vertical blade 13, as described later.

On the other hand, a protrusion 18 of the mounting shaft 17 is provided on the bottom surface 15 of the outlet.
．． A plurality of elongated holes 24 into which 18 can be inserted are formed laterally.

Thus, the vertical blade 13 is attached as follows.

As shown in FIG. 3, after placing the vertical blade 13 sideways and inserting the protrusions 18, 18 of the mounting shaft 17 into the elongated holes 24 (see opening in FIG. 3), when the vertical blade 13 is rotated 90 degrees, the protrusions 1
8.Longitudinal edge 24 of elongated hole 24 between 18 and flange 19
a, 24a are clamped, thereby fixing the vertical blade 13 (see the opening in Figure 3).

In this way, four vertical blades 13.13...
After fixing ・ to the bottom surface 15 of the outlet, fit the notched shaft hole 21 of the connecting rod 16 into the shaft 22 of each vertical blade 13 (the third
(See illustration).

In this case, after the vertical blade 13 is attached, when the vertical blade 13 is rotated to change the wind direction, when the rotation angle α reaches a predetermined angle (for example, 35°), the side surface of the vertical blade 13 will be rotated against the connecting rod 16. It comes into contact with the protrusion 23, and further rotation is restricted (see Figure 4).

Therefore, the protrusions 18, 18 on the side of the vertical blade 13 and the elongated hole 24 are prevented from coinciding with each other, and the vertical blade 13 will never fall off.

Here, the regulation rotation angle α is not limited to 35° in this embodiment, but is set to an appropriate value within the range where the protrusion 18.18 and the elongated hole 24 do not coincide (i.e., within 90°). It is possible.

Next, the effects of the vertical blade mounting structure of the air conditioner according to the present invention will be listed below.

That is, according to the present invention, (1) a pair of protrusions 18, 18 are integrally formed at symmetrical positions of the mounting shaft 17 of the vertical blade 13, and the mounting shaft 17 is attached to the vertical blade mounting surface 15 of the air outlet 8; It is fitted into the formed elongated hole 24 so that the longitudinal edges 24 a of the elongated hole 24 and the protrusion 18.18 can be engaged with each other in the normal mounting position after the vertical blade 13 is rotated. This makes it possible to simplify the assembly work without increasing the number of parts and assembly man-hours compared to the conventional example, and also to prevent falling off after assembly. Since the projection 23 is provided to restrict the rotation angle α of the blade 13 to a range where the projection 18.18 and the elongated hole 24 do not coincide with each other, the vertical blade 13 can be rotated when changing the wind direction. This also has the practical effect that the vertical blades 13 will never fall off unless the connecting rod 16 is removed.
