Description

[Detailed Description of the Invention] This invention relates to an outdoor unit for an air conditioner that facilitates compressor replacement service and makes the product more compact.

Conventionally, as an outdoor unit of an air conditioner installed in this type of compressor, the one shown in FIG. 1 is known. In this FIG. 1, 1 is a compressor. The compressor 1 is surrounded by a compressor soundproof box 2.

Further, 3 is a condenser, an electrical component box 4 is screwed to the condenser 3, and a top blower device 6 is disposed inside the condenser 3. Further, a stop valve 5 is provided near the compressor 1.

The compressor 1, compressor soundproof box 2, condenser 3, and stop valve 5 are mounted on a base plate 7.

In such a conventional outdoor unit of an air conditioner, the electrical component box 4 is fixed to the side plate of the condenser 3 or the base plate 7 with screws, and the stop valve 5 is installed horizontally on the base plate 7. Therefore, it is necessary to remove the compressor soundproof box 2 during the replacement service of the compressor 1, which requires space inside the unit to place the electrical component box 4 and the stop valve 5, which increases the width of the unit. There were some drawbacks.

Furthermore, since the stop valve 5 is attached to the base plate 7, the position of the stop valve 5 is low, resulting in disadvantages such as poor workability.

This invention was made in order to eliminate the above-mentioned drawbacks of the conventional method, and the removable electrical box also serves as a part of the compressor soundproof box, and the stop valve 5 is arranged vertically in the compressor soundproof box. To provide an outdoor unit for an air conditioner that facilitates compressor replacement service, is compact, and has good piping workability by being attached to the unit.

Hereinafter, embodiments of the outdoor unit of the air conditioner of this invention will be described based on the drawings. FIG. 2 is a cross-sectional view showing the configuration of one embodiment.
The figure is a partial sectional view. In both FIGS. 2 and 3, the same parts as in FIG. 1 will be described with the same reference numerals.

The compressor 1 is attached to the front side where a service panel (not shown) for facilitating replacement service of the compressor 1 on the base plate 7 is provided, and is surrounded by a compressor soundproof box 2. This compressor soundproof box 2 has a shape in which a portion of a side surface 2a and a front surface 2b are each opened. Reference numeral 4 designates an electrical equipment box with a front opening 4a, which is provided with a bent portion 4d formed by bending the side surface 4c outward from the front opening edge 4b, and also includes a part of the side surface 2a of the compressor soundproof box 2 and the front surface. Electrical component box 4 in each opening of 2b
The side surface 4c and the bent portion 4d of the compressor soundproof box 2 are made to coincide with each other, and the compressor soundproof box 2 is removably attached to the compressor soundproof box 2 by means of attachment means such as screws. Reference numeral 5 denotes a stopper valve, which is disposed vertically below the electrical component box 4.

A condenser 3 having a substantially U-shaped cross section is attached to the base plate 7 along its periphery, and an upper blower device 6 is disposed above the central portion.

According to the embodiment of this invention configured as described above, the electrical component box 4, which was conventionally mounted on the side plate or base plate 7 of the condenser 3, is replaced with the side surface 4c of the electrical component box 4 and the bent Since the section 4d is also used as a part of the compressor soundproof box 2, and the electrical component box 4 is removably attached to the compressor soundproof box 2, the electrical components can be removed during compressor replacement service. When the box 4 is removed from the compressor soundproof box 2, the opening of the compressor soundproof box 2 can be made wider, so the replacement service for the compressor 1 can be performed without removing the compressor soundproof box 2 from the baseplate 7. Replacement work can be easily performed with the unit still attached.

Furthermore, since the stop valves 5, which were conventionally installed horizontally on the base plate 7, are installed vertically below the electrical component box 4 in the compressor soundproof box 2, the stop valves 5 can be positioned higher, improving work efficiency. At the same time, this improvement is expected, and together with the effect of the above-mentioned method of mounting the electrical component box 4, it is no longer necessary to install the stop valve 5 and the electrical component box 4 on the base plate 7 as in the conventional example shown in FIG. It is possible to create a compact product without creating wasted space within the unit.

As described above, according to the outdoor unit of the air conditioner of this invention, the side surface and the bent portion of the electrical component box are aligned with the openings on the side surface and the front surface of the compressor soundproof box, respectively. In addition to removably attaching the sound box so that it also serves as a part of the sound box, the stopper valves are arranged vertically below the electrical box, so the compressor can be protected even when the electrical box is removed. The opening of the sound box is large, which makes compressor replacement service extremely easy, and the overall structure has the advantage of being compact and improving the efficiency of piping work. In addition, the sides and bent parts of the electrical box are installed so that they match the openings on the sides and front of the compressor soundproof box, so the noise from the compressor does not escape to the outside. When the service panel is set, the soundproofing member becomes double layered, which has the effect of improving the noise prevention function.
