BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handle in an outdoor unit of an air conditioner and a method for attaching the handle.

0002

BACKGROUND OF THE INVENTION In recent years, outdoor units for air conditioners have been increasingly sought after to be quieter, smaller and lighter, and more emphasis has been placed on ease of construction, installation, and serviceability. To help with this, a handle is provided on the cabinet of the product itself, making it easy to move and transport. A conventional air conditioner of this type is disclosed in Japanese Patent Application Laid-Open No. 3-31627.

An example of the above-mentioned conventional air conditioner handle and its attachment method will be described below with reference to the drawings.

FIG. 5 is a sectional view of an outdoor unit of a conventional air conditioner, and FIG. 6 is a perspective view of a handle of a conventional air conditioner.
FIG. 7 is a front view and a side view of a locking piece used for attaching a handle of a conventional air conditioner, and FIG. 8 is a sectional view showing a state in which the handle of a conventional air conditioner is attached.

In FIG. 5, 1 is a compressor, 2 is a heat exchanger, 3 is a refrigerant pipe that connects the compressor 1 and the heat exchanger 2 to form a refrigerant system, 4 is an electrical component, and 5 is an electrical box. be. 6 is a bottom plate on which the components of the compressor 1, heat exchanger 2, refrigerant piping 3, electrical equipment 4, and electrical equipment box 5 are placed. 7 is a front plate, 8 is a rear plate, and 9 is a top plate. 10 is a handle inserted into a square hole drilled in the front plate 7 and rear plate 8; 11 is a handle 10;
This is a locking piece that fits into a through hole provided at the bottom of the.

In FIG. 6, 10a and 10b are handles 10.
10c is a through hole provided in the lower part, which is a stepped hole having a small diameter part and a large diameter part.

In FIG. 7, 11a is the head of the locking piece 11, and 11b is the shaft of the locking piece 11. The shaft portion has overhanging portions 11c on both sides, and the dimension d1 of the shaft portion 11 that is affected by the overhanging portion 11c, the dimension d2 of the shaft portion 11 that is not affected by the overhanging portion 11c, and the through hole 10 of the handle 10.
The relationship between c and the diameter of the small diameter portion is d2<diameter of the small diameter portion of the through hole 10c<d1.

A method for attaching the handle 10 and locking piece 11 to an air conditioner will be described below.

The claw portion 10a formed on the upper side of the handle 10 is brought into contact with the upper side of the square hole drilled in the front plate 7 and the rear plate 8, and is inserted into the product at an angle of about 45° using this point as a fulcrum. The claw portion 10 formed on the lower side of the handle 10 after rotational insertion
Push b into the square hole and insert it. Next, the locking piece 11 is inserted into the stepped through hole 10c provided at the bottom of the handle. The head portion 11a of the locking piece fits into the large diameter portion of the stepped through hole 10c, so that it cannot be easily removed.

0010

However, the above structure has the drawback that force is concentrated on the shaft portion 11b of the locking piece 11, causing it to break, and the handle 10 to easily come off. Also, in this case, there is a concern that people may push their hands into the product through the square hole and touch electrical components or high-pressure piping, causing accidents such as electric shock or burns.
The use of such a safety device also has the disadvantage of resulting in an increase in parts costs and man-hours.

In view of the above-mentioned problems, the present invention provides an inexpensive and reliable handle for an air conditioner and a method for attaching the same.

0012

[Means for Solving the Problems] In order to solve the above problems, the present invention provides a method for slidingly inserting a handle having two flanges on the outer edges of the opening into the opening recesses of the front and rear plates, and then inserting the handle into the opening recess of the front and rear plates. It fixes it.

[0013]

[Function] According to the present invention, sufficient engagement of the handle in the square holes of the front and rear plates is ensured, so that the effect of preventing the handle from coming off is great and the handle can be attached reliably. Furthermore, it is possible to reduce the cost of parts and the number of man-hours.

[0014]

Embodiments Examples of the present invention will be described below with reference to FIGS. 1, 2, 3, and 4. Components having the same configuration as the conventional ones are given the same reference numerals, and detailed explanation thereof will be omitted. Figure 1
1 is a sectional view of an outdoor unit of an air conditioner according to an embodiment of the present invention.

In FIG. 1, 12 indicates a front plate 7 and a rear plate 8.
The handle is inserted into the handle. FIG. 2 is a perspective view of the handle 12.
12a is a front flange formed on the handle 12, 12b is a rear flange, and the front flange 12a and the rear flange 12b are provided with a gap 12c at a constant interval over the front circumference.

FIG. 3 is an exploded perspective view showing a method of attaching the handle 12. Reference numerals 7d and 8d are open recesses provided in the front plate 7 and rear plate 8, respectively, and are inserted into the gap 12c of the handle 12. 13 is a side plate.

FIG. 4 is a sectional view showing the state in which the handle 12 is inserted. The overlapping dimensions e1 and e2 of the front flange 12a and the rear flange 12b are set large.

A method of attaching the handle 12 constructed as described above will be explained below. First, there is a gap 12c of the handle 12 in the opening recesses 7d and 8d provided in the front plate 7 and rear plate 8.
Insert and slide. Next, attach the side plate 13, and
Fix 2.

As described above, according to this embodiment, even if the handle 12 is inserted once and is attempted to be removed, the front flange 12a
, Since the engagement margin of the rear flange 12b is large, the handle 12 can be inserted and inserted securely without coming off. In addition, it is possible to reduce costs because parts costs and man-hours can be reduced.

[0020]

As described above, in the present invention, after a handle having two flanges on the outer edge of the opening is slid into the opening recess of the front and rear plates, the handle is fixed by the side plate.
Sufficient allowance for the handle to fit into the square holes of the front and rear plates is ensured, which greatly prevents the handle from coming off, ensuring secure attachment of the handle, and eliminating concerns about accidents such as electric shock and burns. Furthermore, since the locking piece can also be eliminated, parts costs and man-hours can be reduced, leading to cost reductions.
