BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the structure of an electrical component box for housing a control device for an air conditioner.

[0002]

2. Description of the Related Art FIG. 4 is an overall internal structure diagram for explaining components of an air conditioner of the type according to the present invention shown in, for example, the Mitsubishi Electric Handbook (Package Air Conditioner Edition) 1990 edition. In the figure, 1 is a machine room in which a compressor 2 and the like are installed. Reference numeral 3 denotes an underframe, and a plurality of support columns 4 are fixed to the corners by standing legs. 5 is a utilization side heat exchanger for exchanging heat between air and refrigerant, 6 is an outlet for discharging the heat-exchanged air to the outside, 7a is a blower casing for guiding air to the outlet 6, 7b is a fan, 7c Is a motor for driving the fan, and these casings 7a, fan 7b, motor 7c
The blower unit 7 is configured by. Reference numeral 8 denotes a drain pan for accommodating the drain water condensed and dropped by the use side heat exchanger 5, and is attached so as to be inclined with respect to the horizontal direction. Reference numeral 9 is an electrical component box for housing the control device.

FIG. 5 is a partial internal structural view showing the positional relationship among the compressor 2, the support columns 4, the drain pan 8 and the electrical component box 9. As shown in the figure, the electric component box 9 has a structure in which it is mounted perpendicularly to the column 4 and the mounting surface and the upper surface form a right angle. The electrical component box 9 is fixed to the support column 4 from the machine room 1 side with a screw 10. Further, the control device 11 is fixed in the electric component box 9.

[0004]

Since the conventional air conditioner is configured as described above, it is difficult to work in a low standing posture when the control device 11 in the electrical component box 9 is attached or detached. However, the workability was very poor because of the middle waist posture, and the work time was wasted. In addition, since the angles of the drain pan 8 and the electrical component box 9 with respect to the support column 4 are different, the space between the drain pan 8 and the electrical component box 9 is sacrificed, and there is a problem that a waste space exists.

The present invention has been made to solve the above-mentioned problems, and achieves improvement in workability and serviceability as well as reduction of wasted space, thereby reducing the cost of electricity. The purpose is to provide a product box.

[0006]

The electric component box structure of the air conditioner according to the present invention is such that the mounting angle of the control component of the electrical component box is inclined upward from the horizontal direction by a simple bending of the sheet metal. The top surface of the box is set to the same angle as the drain pan mounting angle.

[0007]

In the electric component box structure of the air conditioner according to the present invention, the control component can be attached and detached obliquely from above by tilting the angle of the control component mounting surface of the electrical component box upward from the horizontal direction. By setting the angle of the upper surface to the same angle as the drain pan mounting angle, the space between the drain pan and the electrical component box can be effectively used.

EXAMPLES Example 1. An embodiment of the present invention will be described below. In the figure,
The same parts as those of the related art are designated by the same reference numerals and the description thereof will be omitted. FIG. 1 is a perspective view of an electric component box 9 of an air conditioner according to the present invention. FIG. 2 is a perspective view showing a state in which the electric component box 9 is fixed to a support. The electric component box 9 is directly fixed to the column 4 fixed to the underframe by a screw 10 from outside the column, that is, from the outside of the apparatus. FIG. 3 is a partial internal structure diagram showing a positional relationship between the compressor 2, the support columns 4, the drain pan 8 and the electrical component box 9. Due to the simple bending of the sheet metal, the mounting angle of the control device 11 in the electric component box 9 is upward from the horizontal direction, and the upper surface of the electric component box 9 is about the same angle as the mounting angle of the drain pan 8. It is attached to the column 4 with the following structure.

Therefore, the control device 11 can be attached to and detached from the electric component box 9 from an obliquely upper position, and the work can be performed in a standing posture from the outside of the air conditioner. Further, the angles of the upper surfaces of the drain pan 8 and the electrical component box 9 are substantially the same, so that the drain pan 8 and the electrical component box 9 can be mounted close to each other.

[0010]

As described above, according to the present invention, the work of attaching / detaching the control device to / from the electrical equipment box is facilitated and the structure is space-saving, so that not only the workability is improved, but also the serviceability and cost are improved. The effect is to obtain a high-quality air conditioner that is also excellent in terms of surface quality.
