DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the above-described conventional configuration, it cannot be said that providing the recess as the finger hooking portion for opening operation is preferable from the viewpoint of design. For that reason, there are some cases where the recess is small and inconspicuous, the opening operation part is difficult to understand, the finger hooking space is small, and the fingers hurt during operation. Also, when the front panel is closed, the claw ribs implanted in the front panel may be broken in some cases, making it impossible to close and fix the front panel.
It was necessary to replace the front panel itself. Further, the structure described later has a problem of increased cost due to an increase in mechanical parts. In view of the above conventional problems, the present invention provides an indoor unit of a separate type air conditioner that is excellent in design aesthetics, has good front panel open / close operability, and is cheaper in cost.

Means for Solving the Problems In order to solve the above-mentioned problems, the indoor unit of the present invention has an upper grill part of the blowing grill, or a lower part of the front panel of the blowing grill so as to cover at least several millimeters at both ends. The finger-hanging operation surface is formed so as to extend substantially in the same shape as the upper edge shape and is used for the opening and rotating operation of the front panel.

Action The action of this means is as follows. According to the present invention, by extending the lower portion of the front panel to the air outlet, the opening and rotating operation of the front panel can be easily and reasonably performed using the relatively large space space called the air outlet.

Installed on. Further, upper and lower blades 6 and left and right blades 8 for changing the wind direction are rotatably provided on the outlet grill 5. Further, a front panel 4 forming a suction port 4a is attached to the front grill 3 so as to be rotatable around an upper shaft hole 4c, and a lower edge 4b of the front panel 4 covers an upper edge 5a of the outlet grill 5. The air outlet 5a extends over the entire length. The substantially key-shaped claw rib 4a on the lower rear surface of the front panel 4 is fitted and fixed in the square hole 3a of the front grill 3 to fix and hold the front panel 4. The opening / closing operation of the front panel 4 at the time of mounting / dismounting for cleaning the filter 10 and the remote control 11 at the time of season on / off is performed by pulling the lower edge 4b of the front panel 4 in the direction of the arrow with the finger rib. 4a is unlocked from the square hole 3a and is rotatable. The lower edge of the front panel, which is the opening rotation operation part, is exposed to the outlet 5a, so to speak, and since it can be operated in a wide space such as the outlet, the flexibility of operation increases, the operation part is easy to understand, and the finger when operating It can eliminate the problem of pain. Since the surface of the front panel 4 is decorated with a hot stamp or the like, the color of the base can be set relatively arbitrarily. By setting the color of the base to be the same as or similar to the color of the air outlet grill 5, the air outlet grill 5 can be formed. The lower edge 4b, which is the base extension portion of the front panel 4, has a structure capable of maintaining an integral view in terms of external design. The third
FIG. 4 and FIG. 4 show another embodiment. Next, referring to FIG. 5, embodiments of the third and fourth aspects of the present invention will be described. Here, the same components as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted. In the figure, the lower edge 4b of the front panel 4 described in FIGS.
Is a resin molded part 12 different from the front panel 4 and is screwed or welded and fixed to form a lower edge. Further, 5b is a cutout portion of the blowout grill 5, and the resin molded component 12 is fitted with a clearance. According to the above, subtle adjustment of the blow-out grill 5 and the resin molded component 12 can be performed as a single item, and adjustment can be performed when the combined screws are tightened. Further, there is an advantage that the opening and rotating operation surface can be made wider depending on the depth setting of the notch. Further, referring to FIG. 6, the fifth aspect of the present invention
The terms are explained. Here, the same components as those in the previous embodiment are designated by the same reference numerals and the description thereof will be omitted. In the figure, 12 is another resin molded part of the front panel 4 of 12 shown in FIG. 5, and 12b is a claw rib in which the claw rib 4a shown in FIG. The resin molded part 13 is fixed to the lower part of the front panel 4 with screws. The claw ribs 4a that were planted in the front panel are eliminated, and the front panel 4 is closed and fixed by the claw ribs 12b that are planted in the resin molded component 12. According to this configuration, by any chance, Even if the claw 12b is broken, the function can be restored by replacing only the resin molded component 12, and it is possible to eliminate the large cost burden of replacing the front panel 4 itself as in the conventional case. Next, referring to FIG. 7, an embodiment of the sixth item of the present invention will be described. Here, the same components as those in the previous embodiment are designated by the same reference numerals and the description thereof will be omitted. In the figure, a ₁ ~
Reference numeral a ₄ is a lateral gap between the adjacent resin-molded component 13 shown in FIG. 6 and the adjacent component forming the lower edge of the front panel 4 described in the previous embodiment. Further, b ₁ and b ₂ are gaps in the lateral direction with the front panel 4 housed in the front grill 3. The relationship between the gaps a _{1 to} a ₂ and the gaps b ₁ and b ₂ is b ₁ ≈b ₂ ≦
The configuration is such that a ₁ ≈ a ₂ ≈ a ₃ ≈ a ₄ . According to this, it is possible to prevent the resin molded component 12 from coming into contact with the adjacent component and the impact damage due to the movement of the clearances b ₁ and b ₂ of the front panel 4 in the case of an unexpected drop.

EFFECTS OF THE INVENTION As is apparent from the above-described embodiments, the present description is based on that the entire length of the upper grill edge of the blowing grill, or the lower portion of the front panel so as to cover at least a few millimeters at both ends, has substantially the same shape as the upper grill edge shape. By forming the extension forming edge surface as the finger hooking operation surface for the opening and rotating operation of the front panel, the operation surface is easy to understand and the problem of finger pain during operation can be eliminated. it can. Also, by making the color of the base of the front panel the same as the color of the outlet grill and similar colors, the outlet grill and the lower extension of the front panel have a structure that can maintain a unified view in terms of appearance and design. Can be supplied. Next, by configuring the lower (extended) edge of the front panel with another resin molded product,
In addition to being able to perform subtle line matching with the blowout grill as a single item, adjustments can also be made when tightening the combined screws, providing a product with a better design. Further, the blowout grill is notched at the entire length of the blowout port or at both ends, and the lower (extended) edge of the front panel or the thickness of another resin molded product can be increased, so that the operation surface is wide and the operation is easier. It will be easier. Further, the claw ribs conventionally planted in the front panel in the other resin molded product, the claw ribs are planted in the other resin molded product, and the front panel is closed and fixed, In the unlikely event that the claw rib breaks, the serviceability is improved because the front panel replacement requires only the replacement of the other resin molded product, which is a small product. In addition, by making the clearance between the lower edge of each front panel and the other adjacent portions thereof larger than the lateral play of the front panel and the front grill, the front panel rattles when dropped,
Since the lower edge of the front panel can avoid a shocking contact with other parts close to the front panel, a more reliable product can be supplied.
