Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a handle used when moving an air conditioner.

Conventional technology Conventionally, this type of handle structure was developed, for example, in 1983-
As shown in No. 81751, it had a structure as shown in Figure 7.

That is, the mounting structure is such that a handle 102 molded from synthetic resin or the like is fitted into a handle hole 101a provided in the outer box 101. Note that the handle hole 101a is designed to fit the handle 102 smoothly.
It is larger than the outer circumference of No. 2.

Next, other conventional techniques will be explained.

As shown in FIG. 8, a handle 202 molded from synthetic resin or the like is fitted into a handle hole 201a provided in an outer box 201, and the mounting structure is such that the outer box 201 is sandwiched between a rib 202a and a handle collar 202b. There is. Note that the handle hole 201a is larger than the outer circumference of the handle 202 so that the handle 202 can be smoothly fitted into the handle hole 201a.

Problems to be solved by the invention However, in the structure shown in Fig. 7, the handle 10
2 into the handle hole 101a, the handle hole 10
Since the outer circumference of 1a is larger than the handle 102, there is a gap, and when the air conditioner is operated, the handle 102 may come off due to vibration, or resonance noise may be generated between the handle 102 and the outer box 101. .

Although the above problem can be solved by eliminating the gap between the handle hole 101a and the handle hole 102, it is actually difficult to process. In particular, handles molded from synthetic resin,
Warpage occurs inward during molding, making it impossible to eliminate gaps.

Furthermore, the structure shown in FIG. 8 is provided with a rib 202a to prevent the handle 202 from detaching or from resonant noise generated between the handle 202 and the outer box 201. However, when the outer box 201 is made of sheet metal, the plate thickness _t1 often varies depending on the thickness of the paint film, etc., so the rib 202a and handle collar 20
When the gap t ₂ between the handles 2b and 2b becomes t ₁ <t ₂ , the handle 202 rattles and a resonance sound is generated.

Also, when t ₁ > t ₂ , the handle 202 becomes the handle hole 201.
I can't get into it. The problem was that they could sometimes leave the group.

Therefore, in view of the above problems, this invention prevents the vibration generated when the air conditioner is operated from being transmitted to the outer box and the resonance sound generated between the outer box and the handle, and at the same time prevents the handle from detaching from the outer box. It is something to do.

Means for Solving the Problems The technical means of the present invention for solving the above problems is to integrally mold a flexible flange on the outer periphery of the handle collar so as to come into contact with the outside of the outer box.

Effect The effect of this technical means is as follows.
In other words, by sandwiching the outer box between the ribs provided above and below the handle and the flexible flange integrally formed on the outer periphery of the handle collar, the flange section exerts a spring effect to prevent wobbling between the outer case and the handle. It is intended to prevent

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1, 2, 3, 4, 5, and 6.

1 has a handle hole 1a in the outer box 1 of the outdoor unit. 2 is a handle molded from synthetic resin or the like, and is provided with a concave portion 2a. A handle collar 2b is provided on the outer periphery of the open end of the aperture recess 2a so as to be in contact with the outer surface of the outer box 1. An upper rib 2c1 and a lower rib 2c2 are provided on the upper surface side 2a1 and lower surface side 2a2 of the aperture recess 2a so as to sandwich the handle collar 2b and the outer box 1, respectively. Further, a flexible flange 2d is provided on the outer periphery of the handle collar 2b so as to be in contact with the outside of the outer box 1, and the flange 2d is shaped so that the tip thereof is narrow and faces outward. t ₁₁ is the thickness of the outer box 1, and t ₁₂ is the gap between the handle collar 2b, the upper rib 2c1, and the lower rib 2c2.

3 is the outdoor unit main body.

In the above configuration, by sandwiching the outer box 1 between the upper rib 2c1 and the lower rib 2c2 of the handle 2 and the flange 2d, the tip of the flange 2d is brought into close contact with the outer box 1 all around.

As described above, by providing the upper rib 2c1 and the lower rib 2c2 of the handle 2 and the flange 2d, the flexible flange 2d is interposed between the outer box 1 and the handle 2, so resonance noise is not generated, and the plate thickness t ₁₁
Even if variations occur such as small or large _t12 and the height of the flange 2d, the only difference will be whether the degree of adhesion is stronger or weaker, and there will be no resonance between the outer box 1 and the handle 2. No sound is generated. In addition, since the handle 2 is in close contact with the outer periphery of the outer box 1, there are no gaps and the appearance is not spoiled, and rainwater etc. do not enter the interior of the outdoor unit main body.

Effects of the invention As described above, the present invention prevents resonance noise from occurring between the outer box and the handle by providing an upper rib and a lower rib at the upper and lower parts of the outer periphery of the concave part of the handle, respectively. will no longer be separated from the outer box. Furthermore, even if the thickness of the outer case varies, resonance noise will not be generated, and since the handle and the outer case are in close contact, the structure is drip-proof. Therefore, it has various advantages such as no problem even if the handle is placed in a place such as electrical equipment that requires drip-proofing.
