For maintenance and inspection of the inside of the air conditioner main body 51, the front panel 52 can be opened upward as shown in FIG.

A mechanism for opening and closing the front panel 52 is shown in FIG. 12 (b). A pair of arms 53a, 53b are provided on the back surface of the front panel 52,
Rotating shafts (pins) 54a and 54b are provided on inner side surfaces of the ends of the arms 53a and 53b, respectively. on the other hand,
The bearing portion 5 having bearing holes 56a and 56b at positions corresponding to the arms 53a and 53b of the air conditioner body 51.
5a and 55b are provided, and arms 53a and 53b are provided.
Of the rotary shafts 54a and 54b of the bearings 56a and 5b, respectively.
It is rotatably inserted in 6b. Therefore, the front panel 52 includes the arms 53a, 53b and the bearing portions 55a, 55.
The air conditioner body 51 is rotatably supported by the air conditioner body 51 via b, and is opened when lifted upward. In addition, the bearing portions 55a, 5 of the arms 53a, 53b

A click claw 58 is also provided on the side surface opposite to the side 3b. When the front panel 52 is opened upward, both click claws 57 and 58 pass each other's click claws 58 and 57 to perform a click operation. By doing so, the front panel 52 can be held in the open state by the engagement.

[0004]

However, in the air conditioner C having the above structure, the arms 53a and 53b are provided.
There is a problem that the rotating shafts 54a, 54b and the like are easily damaged. One of the causes of this is that the rotating shafts 54a of the arms 53a and 53b for attaching and detaching the front panel 52,
54b to the bearing holes 56a and 5 of the bearing portions 55a and 55b.
Arm 53 when inserting into or removing from 6b
Unreasonable bending stress may easily occur in the a, 53b, the rotating shafts 54a, 54b, and the like. That is, when the front panel 52 is attached to the air conditioner main body 51, for example, after holding the front panel 52 and inserting the one rotation shaft 54a into the one bearing hole 56a, the other arm 53b is inserted into the air conditioner main body 51 shown in FIG.
(B) It is necessary to insert the rotary shaft 54b into the other bearing hole 56b while largely bending and expanding in the P direction of (b). Therefore, the arms 53a and 53b and the rotating shaft 54a,
Large bending stress acts on the arm 54a and the arm 53a, 53b.
The rotating shafts 54a and 54b may be damaged, or the arms 53a and 53b and the rotating shafts 54a and 54b may be damaged during use due to residual stress and fatigue even if they are not immediately damaged. In addition, since the arms 53a and 53b have to be widely spread, it is difficult to assemble the front panel 52 and the air conditioner body 51.

Another cause is the front panel 52.
When the is held in the open state, a large stress may occur in the arms 53a and 53b and the rotating shafts 54a and 54b. That is, as shown in FIG.
When holding the open state, click claws 57, 5
8. The clicks 5 of the arms 53a and 53b are engaged with each other.
Since 7 is supported by the click claws 58 of the bearings 55a and 55b, the position of the click claws 57 of the arms 53a and 53b serves as a fulcrum, and the own weight G of the front panel 52 is applied to the base ends of the arms 53a and 53b. , Rotating shaft 54
A large stress F1 is applied to the a and 54b from the bearing portions 55a and 55b. This stress F1 is applied to the arm 53a,
Since the stress is eccentric from the center line of 53b, the arm 53
A moment force is generated in a and 53b, the arms 53a and 53b of the front panel 52 are deformed as shown in FIG. 13, and the front panel 52 is supported in a state where large stress is applied to the rotating shafts 54a and 54b. It will be. While this state continues for a long time or the front panel 52 is repeatedly opened and closed, the arms 53a and 53b and the rotating shaft 54
a, 54b may be damaged, and the arms 53a, 53
There was a problem in the durability of b and the rotating shafts 54a and 54b.
Further, there is a fear that the click claws 57 and 58 are easily disengaged from each other due to the deformation of the arms 53a and 53b.
It is possible to improve the strength by making the arms 53a and 53b strong so as not to be easily deformed, but in that case, the resistance of the click claws 57 and 58 increases and the click operation becomes difficult. There are problems that the operation feeling at the time of opening and closing the panel 52 becomes poor, the click claws 57 and 58 are severely damaged or worn, and it becomes difficult to attach the front panel 52 to the air conditioner body 51.

The present invention has been made in view of the above-mentioned drawbacks of the conventional example, and an object of the present invention is to provide an arm and a shaft supporting portion thereof in an air conditioner in which a front panel is openably and closably held by the arm. It is to provide technology for preventing damage such as.

As shown in, the bush 17 is slid to insert the cylindrical portion 18 into the round hole 21, and the key flange 19 is fitted and fixed in the key recess 20 to restore the arm 7b to the original state. Therefore, when the front panel 2 is attached to the air conditioner main body 1, the amount of bending of the arm 7b can be reduced, and fatigue or damage to the arm 7b and the rotating shaft 8b can be prevented. Further, when removing the front panel 2, the arm 7b can be removed by a procedure opposite to the above procedure without largely bending the arm 7b.

In this way, the bush 17 is fitted and the rotating shaft 8b
Since the slit-shaped opening 22 is closed by the bush 17 in a state in which the bush 17 is pivotally supported,
0b, the rotary shaft 8b has a slit-shaped opening 22.
The rotating shaft 8b can be reliably supported without falling off. Further, although both end surfaces of the tip end portion 16 of the rotating shaft 8b are notched, the non-notched surface is in sliding contact with the inner surface of the bearing hole 11b of the bush 17, so that the rotating shaft 8b may become unstable. Absent. Further, the front panel 2 thus attached to the air conditioner body 1 is held in the open state by the click claws 9 and 12 when the front panel 2 is opened as in the first embodiment, and the arms 7a,
The front end of 7b is held by the lower surface of the backup unit 14.

In the above embodiment, the tip end portion 16 of the rotary shaft 8b is cut out on both sides to have a substantially oval cross section, but one end of the tip end portion 16 of the rotary shaft 8b is cut out to have a substantially semicircular cross section. The bearing portion 10b may be provided with a slit-shaped opening 22 having an opening width corresponding to that. Alternatively, the rotating shaft 8
You may make it cut out both side surfaces only in the central part of b over the same length as the thickness of the bearing part 10b, and let the slit-shaped opening 22 pass in the central part of the rotating shaft 8b. Alternatively, as shown in FIG. 10, the rotating shaft 8b is formed into a round bar shape having the same thickness over the entire length, and the bearing portion 10b has a diameter larger than that of the rotating shaft 8b and a cylindrical portion 18 of the bush 17.
The slit-shaped opening 22 having an opening width smaller than the outer diameter of the slit 22 may be provided. According to FIG. 10, the shape of the rotating shaft 8b can be simplified, the supporting of the rotating shaft 8b becomes stable, and further, the front panel 2 can be attached without bending the arm 7b.

FIG. 11 is a sectional view and a side view showing an example of the structure without the bush 17. By using the bush 17 as in the embodiment of FIG. 6, the rotation of the rotating shaft 8b can be made smooth and the rotating shaft 8b can be prevented from coming off the slit-shaped opening 22. Can be omitted to simplify the structure and mounting of the front panel 2. In this embodiment, the tip end portion 16 of the rotary shaft 8b is cut out on both sides to make the tip end portion 16 of the rotary shaft 8b substantially oval in cross section. A slit-shaped opening 22 is provided toward the front surface of the portion 10b. The slit-shaped opening 22 has a width substantially equal to the narrow side width of the distal end portion 16 and smaller than the outer diameter of the base end portion 15. Therefore, the distal end portion 16 can be passed through the slit-shaped opening 22 by slightly bending the arm 7b and removing the base end portion 15 of the rotating shaft 8b from the side surface of the bearing portion 10b, and the distal end portion 16 can be passed through the bearing hole 11b. After the delivery, the rotary shaft 8b can be inserted into the bearing hole 11b by inserting the base end portion 15 into the bearing hole 11b. In this case, if the angle of the front panel 2 when the tip portion 16 of the rotating shaft 8b and the slit-shaped opening 22 coincide with each other is set to a position slightly higher than the open holding state, the front panel 2 can be opened and closed. It is possible to prevent the front panel 2 from coming off from the air conditioner body 1.

[0023]

According to the first air conditioner of the present invention, when the front panel is held in the open state, a part of the load generated on the axially supporting portion of the arm due to the weight of the front panel is reduced. Since it can be borne by the support means other than the bearing hole, the load generated on the pivotal support portion of the arm is not entirely applied to the rotary shaft of the arm, and the load applied to the rotary shaft is reduced. Therefore, it is possible to prevent the arm of the front panel from being deformed or being damaged by a large stress being applied to the rotating shaft of the arm, and it is possible to improve the durability of the front panel. Further, the engagement means for holding the front panel in the open state is also unlikely to be disengaged.

Further, according to the second air conditioner of the present invention, when the front panel is attached to or detached from the air conditioner body, the pivot shaft is not greatly bent or the arm is not bent. Since it can be attached to the bearing part and can be removed conversely, large bending stress acts on the arm and the rotating shaft to damage the arm and the rotating shaft, or due to residual stress or fatigue, the arm or the rotating shaft may be damaged during use. It is possible to prevent the rotating shaft from being damaged. Furthermore, the work of attaching and detaching the front panel becomes easy. Further, after the rotating shaft is supported by the bush by the bush, the opening of the bearing is closed by the bush, so there is no risk of the rotating shaft coming off the opening, and the rotating by the bush The shaft can also be supported without rattling.

Further, according to the third air conditioner of the present invention, by aligning the narrow portion of the rotary shaft with the opening of the bearing, the rotary shaft is changed from the opening to the bearing hole. Since it can be put in and taken out, the rotating shaft can be attached to and detached from the bearing hole without significantly bending the arm, and a large bending stress acts on the arm and the rotating shaft to damage the arm or the rotating shaft. It is possible to prevent the arm and the rotating shaft from being damaged during use due to residual stress and fatigue. Furthermore, the work of attaching and detaching the front panel becomes easy. Further, when the rotation shaft is pivotally supported by the bearing portion, the narrow portion is displaced from the bearing hole, so that the narrow portion does not come out of the opening portion of the bearing portion. Further, since the narrow portion of the rotating shaft is displaced from the bearing hole, the portion having the original diameter of the rotating shaft is inserted into the bearing hole, and the rotating shaft also stably supports the bearing. The opening and closing of the front panel is also smooth.
