DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner in which a suction grill is rotatably supported at a suction port of a decorative panel.

[0002]

2. Description of the Related Art This type of air conditioner is disclosed in Japanese Utility Model Publication No. 3-36.
As described in Japanese Patent No. 819, a decorative panel having a suction port and an air outlet is attached to an air conditioner body, and a suction grill is pivotally supported at the suction port of the decorative panel. . In such an air conditioner, the base of the long side of the suction grill is rotatably supported near the corner opposite to the long side, and the suction grill is stopped at the end of the suction port by, for example, a slide. A type hook is provided.

[0003]

In the above-described air conditioner, the suction grill is generally made of synthetic resin.
Alternatively, since the shape is rectangular, there is a drawback that the suction grill between the hooks tends to hang down. In order to solve this drawback, when the slide-type hook is provided in the portion that is likely to hang down, it is necessary to change the shape of the suction grill, and there is a risk that a knob for sliding may protrude from the suction grill. . Also,
Since the sliding hook has a large size to be hooked to the end of the suction port, there is a possibility that the hook may not be provided when the device in the air conditioner main body is arranged close to the suction port. In order to eliminate the drawbacks of these sliding hooks, there is a method in which a hook slightly hooking to the end of the suction port is provided on the back surface of the suction grille. Since the hook is configured so as not to be released by the weight of the suction grille or by a slight pull, there is a possibility that the suction grille may be very difficult to open from the decorative panel when opening the suction grille.

[0004] The present invention provides an air conditioner in which the suction grille can be easily opened.

[0005]

The present invention comprises a decorative panel attached to an air conditioner main body, and a suction grill rotatably provided at a suction port of the decorative panel. Along with providing an overhang at the end of the suction port,
In the air conditioner provided on the back surface of the suction grill with a hook that hooks on the overhang portion and a groove into which the overhang portion fits, the groove includes the groove when the suction grill is opened. A guide surface for guiding the overhang to one side of the hook is formed.

[0006]

In this air conditioner, the guide surface guides the overhanging portion at the end of the decorative panel to the hooking side when the suction grill is opened, so that the hooking piece can easily get over the overhanging portion.

[0007]

An embodiment of the present invention will be described with reference to the drawings.

The decorative panel 3 is composed of a main body 2 and a ceiling plate [not shown].
It is installed so as to be airtight.

The decorative panel 3 has an inlet 4 and an outlet 5 formed therein. The inlet has a suction grill 6 and the outlet has a wind direction changing plate 7. The base side 6a of the suction grille 6 is pivotally supported by the decorative panel 3, and the short side of the tip side 6b of the suction grille 6 is slid in the extending direction of the grill to pull the suction grille 6 to the decorative panel 3. A hanging fixture [not shown] is provided. Therefore, a knob for sliding the fixing tool is exposed outside the suction grill 6.

Reference numeral 8 denotes an air filter mounted downstream of the suction grille 6, 9 and 10 denote cross-flow fans provided in the main body 2, 11 and 12 denote fan motors for driving the fans, and 13 and 14 denote the fans. A heat exchanger 15 arranged in a substantially C-shape therebetween, a drain pan 15 for receiving drain from the heat exchanger, and a drain pump 16 for sucking up the drain in the drain pan and discharging the drain out of the main body 2 is there.

In FIG. 1 to FIG. 4, reference numeral 17 denotes a hook made of synthetic resin attached to the back surface of the suction grille 6, which is located substantially in the middle of the long side of the distal end 6b of the suction grille 6.
It is attached at the position of c.

Reference numeral 18 denotes a hook piece formed on the hook 17.
Overhang 2 formed at end 19 of the inlet of decorative panel 3
It is designed to catch 0. Reference numeral 21 denotes a guide surface formed in a curved shape on the hooking piece 18 on the opposite side to the suction grill 6, and when the suction grill 6 is pushed toward the main body 2, the guide surface 21 is provided.
Presses the overhang portion 20 of the end portion 19 of the decorative panel 3 in the direction in which the overhang portion 20 of the end portion 19 of the suction port expands. Reference numeral 22 denotes a guide surface formed as an inclined surface in the groove 23 of the hook 17 and when the suction grill 6 is opened [the suction grill 6 is
When it is pulled to the front side of the
Is guided to the hooking piece 18 side. Since the suction grille 6 is made of synthetic resin, the middle part of the long side of the suction grille 6 on the tip side is particularly easy to hang down,
A hook 17 is attached to the back surface of the suction grille 6 at the portion where the hanging is easy, and the hanging is prevented. Further, since the decorative panel 3 is also made of a synthetic resin, the overhanging portion 20 of the end 19 is easily curved when the suction grill 6 is opened or mounted.

In the air conditioner constructed as described above, the decorative panel 3 is airtightly attached to the ceiling plate or the main body 2 and the decorative panel 3 is at a high position. At the time of maintenance, the user rides on a table or the like and opens the suction grill 6 in an unstable state. At first, the user needs to set the tip side 6 of the suction grill 6.
Slide the fixtures on both short sides of b to release the suction grille 6 from catching on the decorative panel 3.

Then, the user pulls the suction grille 6 toward the front side of the main body 2 by grasping the leading end of the suction grille 6 from which the hook has been removed. When the suction grill 6 is pulled toward the front side of the main body 2, the guide surface 22 is moved to the overhang portion 20 of the end portion 19 of the decorative panel 3.
Of the suction grille 6 and the end 19
Of the hooking piece 17 of the hooking tool 17
Is easy to get over the overhanging portion 20 of the end portion 19 and the hooking piece 18 of the hook 17 is easily detached from the overhanging portion 20 of the end portion 19.

As described above, since the hooking piece 18 of the hooking tool 17 and the overhanging portion 20 of the end portion 19 can easily come off with a small force, the instantaneous balance at which the hooking is released by pulling the suction grill with a strong force. It is possible to prevent the user from overturning or overturning as much as possible, and the maintenance of the air filter 8 and the like can be performed safely and easily.

When the maintenance of the air filter 8 and the like is completed, the user turns the suction grille 6 so that the leading end side is brought into contact with the projecting portion 20 of the decorative panel 3 and slides a hooking tool (not shown). The hook piece of the tool is hooked on the decorative panel 3. Then, when the central portion of the long side of the front end side 6b of the suction grill 6 is pushed toward the main body, the hook pieces 18 of the hook 17
Guide surface 21 pushes the overhanging portion 20 of the end portion 19 of the decorative panel 3 in the direction in which the overhanging portion expands, and the suction grille 6 and the overhanging portion 20 of the end portion 19 are curved. It is easy to get over the overhang portion 20 and easily hook the hook piece 18 of the hook 17 on the overhang portion 20 of the end portion 19.

As described above, since the hooking piece 18 of the hooking tool 17 is easily hooked on the overhanging portion 20 of the end 19, the user is less likely to lose his balance even on a table or the like.

As described above, even when the user is on the table or the like and is in an unstable state, a large force or the like is not required to break the balance when the suction grill is opened or mounted. It is prevented that the user loses his or her balance and falls or is likely to fall on a table or the like. Also, since a large force is not required when opening and mounting the suction grill 6, the opening and mounting of the suction grill 6 can be facilitated.

Further, since the hook 17 is attached to the back surface of the suction grill 6, it is not exposed to the front side, and the hook 17 does not impair the aesthetic appearance. Further, the hooking tool 17 does not process the grill portion of the suction grille 6 and can be hooked by about 1 mm at the end 19 of the decorative panel 3, so that the suction grille 6 can be redesigned. There is no need to remanufacture. For this reason, for example, it is determined that the suction grille does not hang down, and as a countermeasure in a case where a portion where the hooking device 17 and the like are not attached unexpectedly hangs down, it is possible to attach the hooking device 17 to the suction grille.

In this embodiment, the suction grill 6 and the hook 17 are formed separately, and the guide surface 22 is formed as a flat inclined surface.
7 may be formed integrally, or the guide surface 22 may be formed by a curved inclined surface.

Furthermore, in this embodiment, the description has been made of the case where the main body 2 is arranged in the ceiling space. However, the main body 2 is hung from the ceiling plate to the indoor side, hung on the wall, or placed on the floor. It may be something.
