Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an internal structure of an outdoor unit of an air conditioner, and more particularly, to a mounting structure of an electrical box disposed in the outdoor unit.

[0002]

2. Description of the Related Art The internal structure of an outdoor unit of a conventional air conditioner will be described below with reference to FIGS.

FIG. 5 shows a conventional structure for fixing an electrical box. In FIG. 5, a heat exchanger 2 is disposed on a bottom plate 3, a propeller fan 4 is disposed opposite the heat exchanger 2, and a motor of the propeller fan 4 is attached to a mounting angle 6 erected on the bottom plate 3. Fixed. The outdoor unit is provided with a compressor (not shown) for pumping the refrigerant to the heat exchanger 2.

Further, the electrical component box 1 is fixed to a tube sheet 2 ′ at the end of the heat exchanger 2 with screws 5.

FIG. 6 shows a fixing structure of another electrical component box. In FIG. 6, the electrical component box 1 is locked to the heat exchanger 2 by a locking member 10 formed on a side surface of the electrical component box 1 instead of the screw. Further, the locking member 1
0 is provided with a buffer member 7.

As shown in FIGS. 7 and 8, the top plate 8 is mounted on the side plate 11, and the locking member 10 holds down the heat exchanger 2 by the top plate 8 via the buffer member 7.
Thus, the electrical box 1 is fixed in the outdoor unit.

[0007]

In the conventional fixing structure as described above, in order to fix the electrical box 1, an operation of screwing and an operation of attaching a cushioning member are required. There was a need for a reduction in work processes.

An object of the present invention is to solve the above-mentioned problems of the prior art, and to provide an inexpensive electrical box fixing device capable of reducing the number of assembly steps.

[0009]

In order to achieve the above object, an air conditioner according to the present invention has a heat exchanger disposed on a bottom plate and a heat exchanger provided on the bottom plate. In an outdoor unit of an air conditioner provided with an electrical component box to be locked and a top plate that covers the heat exchanger and the electrical component box, a locking member that locks the electrical component box on the upper part of the heat exchanger; An elastic member is formed integrally with the electrical box and presses the electrical box against the heat exchanger in contact with the top plate.

According to a second aspect of the present invention, the elastic member is
The locking member is provided on a surface facing the top plate. According to a third aspect of the present invention, the locking member is formed from sheet metal, and the elastic member is formed by cutting and raising the locking member. Claim 4
In the described invention, the locking member is formed of resin, and the elastic member is formed integrally with the locking member.

[0011]

1 to 4 show an embodiment of an outdoor unit of an air conditioner according to the present invention. In addition,
The same parts as those in the conventional example are denoted by the same reference numerals.

In FIG. 1, a heat exchanger 2, a propeller fan 4 and the like are disposed on a bottom plate 3, and an electrical component box 1 is disposed above the propeller fan 4. In addition, a compressor (not shown) is provided in the outdoor unit to pump the refrigerant to the heat exchanger 2. The electrical component box 1 is locked on the upper part of the heat exchanger 2 by a locking member 10, and an electrical component board (not shown) is provided in the electrical component box 1. Further, the electrical component box 1 is formed by bending a sheet metal or integrally molding with a resin.

The locking member 10 has an inverted L-shape when viewed from the side, and is formed integrally with the electrical box 1. When the locking member 10 is a sheet metal, the claw 9 (elastic member) is formed by cutting and raising the upper surface of the locking member 10 so as to protrude toward the top plate 8. Alternatively, when the locking member 10 is made of resin, the claw 9 (elastic member) is integrally formed so that the upper surface of the locking member 10 protrudes toward the top plate 8.

FIGS. 2 and 3 show a locking member 10 having claws 9.
FIG. 4 is an enlarged view of a main part in a state where a top plate 8 is attached to the fin. Figure 2
As shown in FIG. 3, the electrical component box 1 is locked on the heat exchanger 2 by the locking member 10, and the top plate 8 is disposed above the electrical component box 1. The claw 9 is located between the heat exchanger 2 and the top plate 8, and is fixed on the side plate 11.
The electrical box 1 is fixed in the indoor unit by abutting the inner surface and pressing the electrical box 1 against the heat exchanger 2.

The protruding length of the claw 9 in the direction of the top plate 8 is slightly larger than the gap A formed between the top plate 8 and the locking member 10, that is, (A + α) as shown in FIG. When the top plate 8 is attached, the electrical component box 1 is necessarily pressed against the heat exchanger 2 with an appropriate pressing force.

[0016]

As described above, according to the first aspect of the present invention, the locking member for locking the electrical box on the upper part of the heat exchanger, the locking member formed integrally with the electrical box and abutting on the top plate. Since the electric box is provided with an elastic member for pressing the heat exchanger against the heat exchanger, it is not necessary to use a separate component such as a screw or an additional component (buffer member), thereby reducing the manufacturing cost. Further, it is possible to prevent the rotation of the compressor from being transmitted to the electrical box and generating abnormal noise such as chattering noise.

According to the second aspect, since the elastic member is provided on the surface of the locking member facing the top plate, the force applied to the elastic member is transmitted to the heat exchanger via the locking member. Therefore, unnecessary pressing force is not applied to the electrical box.

According to the third aspect, the locking member is formed from sheet metal, and the elastic member is formed by cutting and raising the locking member. Therefore, the cut and raised state can be easily changed,
The elastic force of the elastic member can be easily adjusted.

According to the fourth aspect, the locking member is formed of resin and the elastic member is formed integrally with the locking member. Therefore, unlike the case where a sheet metal is formed, the time required for cutting the locking member is reduced. The elastic member can be formed simultaneously with the formation of the locking member.
