DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes an air conditioner main body. The air conditioner main body 1 is hooked on hanging bolts 3 suspended from the ceiling and is installed and fixed on the lower surface of the indoor ceiling plate 5. The air conditioner body 1 has an electrical box 1
1, various devices such as a blower 13, a heat exchanger 15, a refrigerant pipe 29, and the like are stored with almost no gap. The blower 13
As shown in FIG. 2, the motor comprises four blower units 21 to 24, each of which has a rotating shaft 27 driven by one motor 25.
Fixed and arranged.

The heat exchanger 15 is a fin-tube type heat exchanger as shown in FIG. 1, and is installed obliquely in the air conditioner body 1. This heat exchanger 15 has a refrigerant pipe 29
The refrigerant pipe 29 is led out of the air conditioner main body 1 and has a compressor, a pressure reducing device, and a compressor of an outdoor unit (not shown).
Connected to an outdoor heat exchanger and the like.

Below the heat exchanger 15, a drain pan 31 made of styrene foam is installed as shown in FIG.
A sheet metal panel 33 is provided on the lower surface of the drain pan 31. As shown in FIG. 2, a drain pump unit 35 is connected to the drain reservoir 31a of the drain pan 31 via a flexible tube 32. And discharge it out of the air conditioner body 1.

As shown in FIG. 1, a suction grille 37 made of resin is installed below the blower 13 so as to be openable and closable, and an air purification filter 39 is attached to the suction grille 37. When the blower 13 is driven, the suction grill 3
The air in the room is sucked into the air conditioner main body 1 through the filter 7 and the filter 39, and the air is heat-exchanged in the heat exchanger 15 and then blown into the room through the outlet 41. Reference numeral 43 denotes a middle partition plate that partitions substantially the center of the air conditioner main body 1 transversely.

In this embodiment, as shown in FIGS. 3A to 3C, the suction grill 37 is integrally formed of resin. The suction grill 37 has a substantially rectangular shape, and the one end side frame member 36 is provided.
A, the other end side frame member 36B, and a plurality of horizontal rails 38, and a suction opening is provided between the plurality of horizontal rails 38. One end 37A of the suction grill 37 is supported by a sheet metal panel 33 via a hinge 51 (see FIG. 1), and the suction grill 37 has one end 37A as an axis and the other end 37B at the air conditioner body 1.
It is configured to be openable and closable so as to rotate in an arc from.
The other side frame member 36B of the suction grill 37 has a horizontal rail 3
Two flat portions 57 are formed in a direction orthogonal to 8, and a hook portion 100 made of resin is slidably mounted on these flat portions 57, as shown in FIG. 4A. The hook pieces 100 pass through the through holes 55 of the other end side frame member 36B of the suction grill 37, and as shown in FIG.
3 is locked in a hook piece receiving hole 53 formed in the hook piece 3.

FIGS. 5A to 5C show the surface of the hook piece 100.
As shown in D, a protrusion 63 is provided integrally, and a slit 59 extending in the width direction is formed in the protrusion 63. A pair of legs 67 are integrally provided on the back surface of the hook piece 100. Reference numeral 71 denotes a screw hole for passing a screw 75 (see FIG. 4B). Referring to FIG. 4A, hook piece 1
The hook pieces 100 are provided in the hole walls of the through holes 55 through which
The protrusion 65 that engages with the projection 63 is integrally provided. In addition, a groove 69 is provided in the flat portion 57 of the other end side frame member 36B so as to engage with the leg 67 of the hook piece 100.
The groove 69 defines a moving distance of the hook piece 100.

In this type of air conditioner, the suction grill 37 is opened and closed each time the filter 39 is maintained, for example. When the suction grille 37 is closed, as shown in FIG. 4A, the suction grille 37 is turned to a predetermined closing position via the hinge 51, and then hooked in the direction of arrow A at the closing position. The piece 100 is slid. Then, as shown in FIG.
The locking portion 102 of the suction grille 37 is locked in the hook piece receiving hole 53 of the sheet metal panel 33.
Are fixed to a sheet metal panel (air conditioner body 1) 33.

In this embodiment, as shown in FIG.
When the hook piece 100 is slid in the direction of arrow A,
As shown in FIG. 4B, the protrusion 65 contacts the convex portion 63,
The projection 63 is pressed downward. In this case, since the slit 59 extending in the width direction is formed in the convex portion 63,
When the convex portion 63 is pressed downward, the slit 59 contracts, and a repulsive force is generated due to the elastic deformation. As shown in FIG. 4B, when the projection 63 passes through the projection 65, the projection 63 is released from the pressing force by the projection 65, so that a so-called operation click feeling is obtained. In order to provide a click feeling, it is desirable that the slit 59 be formed almost completely in the width direction.

A screw hole 71 is provided substantially at the center of the hook piece 100. When the suction grill 37 is closed, a screw 75 is screwed into the screw hole 71 as shown in FIG. The hook piece 100 is fixed by the screw 75,
The hook piece 100 is not slid by mistake, and safety can be improved.

In this embodiment, the hook portion 100 is integrally provided with the convex portion 63 having the slit 59, while the through-hole 55 of the other end side frame member 36B through which the hook portion 100 penetrates.
Since only the protrusions 65 engageable with the projections 63 are provided integrally with each other, the manufacturing costs of the hook pieces and the suction grille hardly increase. Then, with a simple configuration, a so-called click feeling in operation can be generated.

As described above, the present invention has been described based on one embodiment, but the present invention is not limited to this. For example, the shape of the sliding hook piece is not limited to the above shape, and can be changed without departing from the spirit of the present invention.

[0022]

According to these inventions, while the hook piece is provided with the protrusion having the slit extending in the width direction, the hook piece can be engaged with the through-hole of the other end side frame member through which the hook piece passes. Since only the protrusions are provided, a so-called click feeling in operation can be generated with a simple configuration without substantially increasing the manufacturing costs of the hook pieces and the suction grille.
