Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grill device provided at, for example, an air inlet or an air outlet of an air conditioner.

[0002]

2. Description of the Related Art FIG. 5 shows an indoor unit of a conventional air conditioner. This indoor unit is a rear plate body 1
A front panel 2 is attached to the front surface of the case body 3 to form a case body 3. The case body 3 is provided with an air inlet 4 and an air outlet 5.

The front panel 2 is provided with a suction grill 6 corresponding to the air suction port 4. The front panel 2 and the suction grill 6 are integrally formed of a synthetic resin material. Inside the case body 3, there are an indoor heat exchanger 8 and a fan 9
Etc. are incorporated.

In order to improve the image, the suction grill 6 often has a slant grill structure composed of a plurality of slanting horizontal crosspieces 11 as shown in FIGS. 6 (A) and 6 (B). .

Several vertical rails 12 are provided to reinforce the plurality of horizontal rails 11. The vertical rails 12 are arranged behind the horizontal rails 11 in order to make them inconspicuous in appearance. The horizontal rail 11 and the vertical rail 12 are connected by a rib 13.

The molds 15 and 16 used when molding the suction grill 6 are opened and closed in a direction perpendicular to the front surface of the suction grill 6, as shown in FIG. Therefore, the gap G between the front end of each horizontal rail 11 and the rear end of the adjacent horizontal rail 11 needs to be about 1.5 mm or more, and the upper ends of the ribs 13 have a slight downward slope toward the front side. It is formed on a flat end surface 17 having a draft.

[0007]

However, since the above-mentioned gap G is provided, not only the vertical bars 8 can be seen from the front through this gap G, but also the components inside the indoor unit can be seen. Therefore, a neat appearance cannot be obtained, and color matching with built-in parts installed in the indoor unit is required, which adversely affects standardization of parts and cost.

When the suction grill 6 is white, as shown in FIG. 1A, the indoor illumination light obliquely entering from between the horizontal bars 11 is reflected on the flat end surface 17 of the upper end of the rib 13.
The reflected light illuminates the diagonally front side of the horizontal crosspiece 11 immediately above, and projects the illuminating portion 18 visible from the front as shown in FIG. Since the illuminating portion 18 looks like a substantially straight line continuous with the vertical crosspiece 12, there is a drawback that the appearance is impaired.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a rib that hardly reflects indoor illumination light or the like which is obliquely entered from between the horizontal crosspieces, and even if it does not reflect light. Even if the parts that are illuminated as extremely weak light are inconspicuous, the interior cannot be seen through the gaps between the horizontal bars, and the material and color of the grill are not specified, improving aesthetics and standardizing parts and reducing costs. An object is to provide a grill device.

[0010]

In order to satisfy the above object, the present invention provides a plurality of cross rails diagonally arranged on the front surface of the grill portion with a high front end and a low rear end, and on the back surface of the cross rail. In a grill device comprising a reinforcing vertical bar provided and a rib connecting the horizontal bar and the vertical bar, the rib is attached to the rear surface of the horizontal bar at an angle of 90 ° or more with respect to the front surface of the grill portion. The grill device is characterized in that it is formed along with each other and the gap between the front end of each horizontal rail and the rear end of the adjacent horizontal rail is set to zero or lapped.

[0011]

The indoor illumination light or the like that enters obliquely from between the horizontal rails is hardly reflected by the ribs, so that even if there is reflected light, the portion illuminated by this light is inconspicuous.
In addition, the ribs, vertical rails and built-in parts are not visible, giving a neat appearance. The material and color of the grill are not specified, which increases the freedom of design.

[0012]

1 to 4 show one embodiment of the present invention.

FIG. 2 shows an indoor unit 20 of the air conditioner. In this indoor unit 20, a front panel 22 is attached to the front surface of a rear plate body 21 to form a case body 23. The case body 23 is provided with an air suction port 24 and an air outlet port 25. Front panel 2 above
2, a suction grill 26 is provided corresponding to the air suction port 24.

As shown in FIG. 3, the front panel 22 and the suction grille 26 are formed as separate bodies, and are molded with a synthetic resin material. The suction grill 26 includes a peripheral frame 27 and a grill portion 28 which are integrally formed. The corner portion 29 of the peripheral frame 27 has no corners and is rounded.

As shown in FIGS. 1 and 4, the grill portion 28 is provided with a plurality of diagonal rails 30 ... Which are arranged diagonally with a high front end and a low rear end, and on the back side of the horizontal rails 30. The vertical rail 31 for reinforcement is formed, and the horizontal rail 30 and the vertical rail 31 are connected by a rib 32.

As shown in FIG. 1, the ribs 32 connecting the horizontal rail 30 and the reinforcing vertical rail 31 in the suction grill 26 have an angle θ of 90 ° or more with respect to the front surface of the grill portion 28 and the horizontal rail 3 is formed.
It is formed along the rear surface 33 of 0, and is formed in a so-called U-shape.

The gap G between the front end of each horizontal rail 30 and the rear end of the adjacent horizontal rail 30 is formed to be zero. Therefore, when the grill portion 28 is viewed from the front as shown in FIG. 4, the front end of the horizontal rail 30 and the rear end of the adjacent horizontal rail 30 coincide with each other, and the gap G cannot be seen.

The suction grille 26 is injection-molded from a thermoplastic resin. At this time, the pair of molds is molded with the horizontal rail 30 being tilted by an angle θ and the horizontal rail 30 being horizontal. do it.

That is, if the molds are formed so as to open and close in the horizontal direction (direction of the horizontal rail 30), the molds can be reliably removed. In this way, the suction grill 26 having the above structure can be easily obtained.

However, in the grill portion 28, the ribs 32 are formed along the rear surface of the cross rail 30 at an angle θ of 90 ° or more with respect to the front surface of the grill portion 28, as shown in FIG. Since the rib 32 is formed in a U shape, the upper end surface 34 of the rib 32 has substantially the same shape as the rear surface 33 of the horizontal rail 30.

Of the indoor illumination light obliquely entering from between the horizontal rails 30, very little light strikes the upper end surface 34 of the rib 32. Even if there is a slight amount of light reflected on the upper end face 34, this is all directed to the rear side because the inclination of the rib 32 is set.

Then, the light reflected again on the rear side is further attenuated, and is not noticeable from the front side. In other words, the light reflected by the ribs 32 does not illuminate the lower surface of the horizontal rail 30, and does not illuminate brightly as a shining portion that can be seen from the front as in the conventional case. Therefore, there is no problem even if the color of the suction grill 26 is white.

Since the gap G between the front end of each horizontal rail 30 and the rear end of the adjacent horizontal rail 30 is set to zero, the grill portion 28 is
When viewed from the front, the gap G is invisible and
The vertical bar 31 is also invisible.

Of course, the parts inside the indoor unit 20 are completely invisible from the cross rails 30 and have a neat appearance by being blocked from the field of view, and the color matching with the built-in parts installed inside the indoor unit 20 is unnecessary. Become.

In the above embodiment, the gap G between the front end of each horizontal rail 30 and the rear end of the adjacent horizontal rail 30 is set to zero, but it is not limited to this, and the front end of the horizontal rail 30 is not limited to this. And the gap between the rear end of the adjacent horizontal rail 30 is zero or more, that is, the horizontal rail 3
The rear end of the adjacent horizontal rail 30 may be made lower than the front end of 0 to be wrapped.

In this way, even when the grill portion 28 is seen from slightly above the front, the vertical gap 3 and the vertical bar 3 are naturally obtained.
1. By blocking the components inside the indoor unit 20 from the field of view, the effects more than those of the above embodiment can be obtained.

[0027]

As described above, according to the present invention, the rib connecting the horizontal rail and the vertical rail is formed along the rear surface of the horizontal rail at an angle of 90 ° or more with respect to the front surface of the grill portion. Since the gap between the front end of each horizontal rail and the rear end of the next horizontal rail is set to zero or wrap, even if the indoor illumination light that enters diagonally between the horizontal rails is reflected by the ribs, this The reflected light is extremely weak, the illuminated part is hardly noticeable, and the gap between the front end of each horizontal rail and the rear end of the next horizontal rail is invisible,
The ribs, the vertical bars, and the built-in components are blocked from the field of view, and the appearance is clean, and the material and color of the grille are not specified, which contributes to standardization of components and cost reduction.
