Description

[Detailed Description of the Invention] This invention relates to an air conditioner, and more particularly to an air conditioner equipped with an electrical component storage box (hereinafter referred to as an electrical component) that can cool electrical components.

In recent years, air conditioners have become smaller and their components have been arranged in a three-dimensional manner, rather than in a two-dimensional arrangement as in the past.

The electrical box that stores electrical components is no exception, and is often placed in the space above the compressor.

In such a case, the temperature of the air around the compressor rises as the compressor becomes hot, which reaches the area around the electrical box due to convection and stagnates there, causing the temperature of the electrical parts to rise and causing damage to the electrical parts. There is a risk of damage.

This invention is intended to eliminate the above-mentioned drawbacks, and will be described below based on one embodiment. FIG. 1 is a perspective view showing the structure of an air conditioner, with the cabinet removed.

FIG. 2 is a perspective view showing the internal structure of the electrical box, with the main body of the electrical box and the cover separated.

FIG. 3 is a cross-sectional view taken along the Z-Z line in FIG. 1 with the electrical box main body and the cover set.

In FIGS. 1, 2, and 3, 1 is a compressor, 2 is an electrical box body placed above the compressor, and 3 is a cover.
An electrical component box is formed by covering the upper part of the electrical component box main body 2 with a cover 3, and electrical components 4 are housed inside.

5 is a condenser, and 6 is a blower.

Air sucked in from around the condenser 5 passes through the condenser 5 and is blown out forward by the blower 6.

Reference numeral 7 denotes a cabinet of an air conditioner, and an inlet 8 for sucking air is provided on the top surface and the upper side of the cabinet.

The electrical component box main body 2 is hollowed out from a base 9, front and rear side walls 10.11, and a rib 12 projecting upward from the base 9, and the side and top surfaces without the side walls 10.11 are open.

Rib 12 is formed to connect side walls 10 and 11, and its height is smaller than the height of side walls 10.11.

The cover 3 is separated from the top surface 13 and side wall 14, and has an abbreviated font.

An opening 15 is provided in the side wall 14, and the upper end of the opening 15 is located at a lower position than the upper end of the rib 12 when combined with the electrical component box main body 2.

The opening 15 also serves as an air passage 16 for air sucked into the blower 6.
facing.

Next, the operation will be described. When the air conditioner is operated, the compressor 1 is operated and the blower 6 is rotated to suck air from around the condenser 5.

The air around the compressor 1 is warmed by the rise in the temperature of the compressor 1 and reaches the upper electrical component box body 2 by convection.

At this time, the air in the air passage 16 is sucked by the blower 6, and since the right side of the electrical box main body 2 is open, the air is sucked into the electrical box as shown by the arrow, and the rib 12 and cover 3 The air passes through the gap 17 formed by the top surface 13, passes through the gap 18 formed by the side wall 14 of the cover through the rib 12, and is guided to the air passage 16 through the opening 15.

Therefore, the air heated by the compressor 1 does not stagnate around the electrical component box, and the temperature of the electrical component 4 does not rise, so there is no risk of damage to the electrical component 4.

Further, since the upper end of the opening 15 is located at a lower position than the rib 12, even if rainwater enters from the suction port 8 of the cabinet 7, it will not splash on the electrical components 4, and there is no risk of insulation failure.

As described above, the air conditioner of this invention utilizes the suction force generated by forced air blowing to the condenser to blow air inside the electrical box through the gap formed between the ribs of the electrical box and the cover. Since the structure is configured so that air flows to the condenser side, the electrical component box is sufficiently cooled, and the electrical components can be placed above the compressor, making it possible to downsize the air conditioner. It has an extremely large effect.

In the above embodiment, the rib protrudes from the base of the electrical box main body, but the same effect can be obtained by providing a left side wall on the electrical box main body and making the height of this side wall lower than the other side walls. .

[Brief explanation of the drawing]

Fig. 1 is a perspective view of an air conditioner incorporating an electrical box of this invention with the cabinet removed, Fig. 2 is an exploded perspective view of the electrical box of this invention, and Fig. 3 is an exploded perspective view of the electrical box of this invention. FIG. 2 is a sectional view taken along line 2 in FIG. 1, showing a state in which the electrical component box body and the cover are set. In the figure, 1 is a compressor, 2 is an electrical box main body, 3 is a cover, 4 is an electrical component, 9 is a base, 10.11 is a side wall, 12 is a rib, and 15 is an opening.
