DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner, and more particularly to an air conditioner having a blowout frame.

[0002]

2. Description of the Related Art Generally, as shown in FIG. 3, an air conditioner 1 is provided with an air inlet 2 and an air outlet 3 as shown in FIG. 3, and the air outlet 3 has a wind direction. A change device 4 is provided. The wind direction changing device 4 changes a blowing direction by manually or automatically turning a blade.

[0003] The blades of the wind direction changing device 4 have vertical blades (vertical louvers) 5 for guiding air in the horizontal direction (longitudinal direction of the outlet 3) and air in the vertical direction (short direction of the outlet 3). A horizontal blade (horizontal louver) 6 for guiding is provided. FIG. 3 shows two horizontal blades 6 as an example.

[0004] By combining these vertical blades 5 and horizontal blades 6, it is possible to blow air in various blowing directions, such as a diagonally lower right direction and a diagonally upper right direction.

FIG. 4 is a sectional view of the conventional air conditioner 1 shown in FIG.
FIG. 3 is a cross-sectional view taken along line A, showing an air outlet passage 3, a reinforcing frame 10 of a grill 7, and a frame (outer case) 8
2 shows a fitting portion of FIG. A plurality of horizontal blades 6 are rotatably attached to the reinforcing frame 10 via shafts 11, respectively.

FIG. 5 is an enlarged view of a portion where the peripheral frame 13 of the reinforcing frame 10 is attached.

The peripheral frame 13 of the reinforcing frame 10 is fitted in the fitting hole 12 of the bottom plate 9. That is, the peripheral frame 13 is engaged with the edge 14 of the outer case defining the fitting hole 12 and the edge 15 of the front panel. The peripheral frame 13 has a front panel 16 on the downstream side of the air outlet and an outer case 17 on the upstream side of the air outlet, and reinforcing ribs 18 are provided only on the front panel 16 among them. The reinforcement frame 10 is reinforced only by the ribs 18 of the front panel 16. In the hole 19 of the base 13,
The vertical blade 5 is fitted and fixed.

[0008]

By the way, in such a fitting structure of the peripheral frame 13 of the reinforcing frame 10, as shown in FIG. 5, the reinforcing frame 10 of the air outlet 3 and the grill 7 or the outlet Actually, in the fitting portions X and Y between the frame 3 and the frame 8, some play is provided in anticipation of an error in the production of the mold of each part.
It is preferable that the fitting parts of the reinforcing frame 10 and the frame 8 look linear.

However, in the conventional case, since the outer case 17 has no ribs, the outer case 17 is easily deformed, and in the fitting portion Y, the mismatch between the reinforcing frame 10 of the outlet 3 and the frame 8 is likely to occur (play is generated). Problem).

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has a simple structure, and a reinforcing frame of an air outlet and an outer case are linearly set without mismatching of fitting. The purpose is to provide an air conditioner that can be shown clearly.

[0011]

Means for Solving the Problems] Therefore, the present invention includes a outer case, to constitute a machine body having an outlet passage of a front panel attached to the exterior case, between the outer case and the front panel, the I will define the bottom of the outlet passage
So as to partition the surrounding frame and the blow-out passage.
A blowing frame having a reinforcing frame attached to the surrounding frame
In the attached air conditioner, the upstream side of the surrounding frame
When the first convex portion engaging with the outer case is provided separately,
A second portion that engages with the front panel at a downstream portion of the peripheral frame.
2 is provided, and the reinforcing frame is provided at an upstream portion of the reinforcing frame.
A first rib thicker than the thickness of
A second rib thicker than the thickness of the reinforcing frame,
A second fitting formed between the outer case and the first convex portion;
A mating portion sandwiched between ends of the first rib, and
A first fitting portion formed between the panel and the second convex portion
Is sandwiched between the ends of the second rib .

[0012]

In the above construction, ribs are provided not only on the downstream side of the air outlet of the reinforcing frame but also on the upstream side of the air outlet of the reinforcing frame, so that the reinforcing frame can be securely attached to the frame. it can.

[0013]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, a case 4 of the air conditioner 33 is shown.
Within 0, the heat exchanger 35, the blower 37, the air purifier 39
It has. Further, an air inlet 31 is formed in front of and obliquely above the case 40 of the air conditioner 33, and an air outlet passage 43 is formed diagonally below the front.

The bottom plate 5 of the frame 48 is
9 and the drain pan 97 define an outlet passage 99 for guiding the air after heat exchange. The air blowing passage 99 is provided with a wind direction changing device 44. The wind direction changing device 44 changes a blowing direction by rotating a blade.

The blades of the wind direction changing device 44 are provided with vertical blades (vertical louvers) 45 for guiding air in the horizontal direction (longitudinal direction of the outlet passage 43) and air in the vertical direction (transverse direction of the outlet passage 43). A horizontal blade (horizontal louver) 46 for guiding is provided, and by combining the vertical blade 45 and the horizontal blade 46, it is possible to blow air in various blowing directions such as a diagonally lower right direction and a diagonally upper right direction. I can do it.

In the fitting portion of the air blowing passage 43, the blowing frame 47, and the frame 48, the reinforcing frame 50
A plurality of horizontal blades 46 are mounted so as to be rotatable about a shaft 51 in the direction of arrow T.

FIG. 2 is an enlarged view of a portion where the peripheral frame 53 of the reinforcing frame 50 is attached.

In FIG. 2, an outer case 75 and a front panel
