DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the illustrated embodiments. FIG. 1 is a perspective view showing an example of a closing valve mounting structure in an outdoor unit of the present invention. This outdoor unit has the same configuration as that described in FIG. 4 except that the accumulator fixing plate 3 is used instead of the side plate 30 (see FIG. 4) as a supporting member for the mounting plate, and the same members are the same. Numbered. The compressor 27 has two accumulators 28 and 29, and the lower end 29 a of the accumulator 29 is fixed to the bottom plate 1 of the chamber 24 via the fixing base 2. The accumulator 29 is hidden by the side plate 30 in FIG. The accumulator fixing plate 3 has an L shape and is arranged in the chamber 24, and the base end 3a is an end fitting 4 of the heat exchanger 26.
The inner surface of the bent portion 3b is fixed to the outer circumference of the upper portion 29b of the accumulator 29.

Moreover, in this state, since the side plate 30 as in the conventional example of FIG. 4 is not provided, the operation of the refrigerant pipe, the visual inspection for hitting the pipe and the gas leak inspection thereafter are not restricted in the direction, and the operation portion 32a is provided. Since there is no hindrance to the opening and closing of the downward closing valves 32 and 33 by a spanner or the like, the workability of assembling the outdoor unit is improved.

Further, the tip 3c of the accumulator fixing plate 3
Since the spacer 5 is interposed between the mounting plate 31 and the end 31a of the mounting plate 31, the vibration transmitted from the compressor 27 to the mounting plate 31 via the accumulator 29 and the accumulator fixing plate 3 is mitigated, and the vibration of the closing valve The operation parts 32a and 33a are not loosened and the refrigerant pipe is not damaged.

FIG. 3 shows the appearance of the outdoor unit,
This outdoor unit has a devised structure for mounting the top plate 12 of the case 21 so that the electric component box 11 inside can be taken out from the front when other same outdoor units are arranged vertically and horizontally.
That is, the top plate 12 is fixed to the case 21 at four positions shown in the figure due to the relationship of the intake passage of the fan 25, and three of them are fixed by the screws 13a, 13b, 13c,
A bolt 15 having a head larger than its width is passed through an elongated hole 14 on the side of the top plate and screwed into the case. The rear screw 13c is loosely stopped so that the front edge of the top plate 12 can be opened. The electrical component box 11 is taken out from the outdoor unit as follows. That is, the two screws 1 on the front edge of the top plate 12
3a and 13b are removed, and the front edge is lifted and opened about 20 mm as shown by the chain double-dashed line in FIG. 3 (B). At this time, since there is a gap of about 20 mm between the outdoor units that are vertically and horizontally connected, there is no hindrance to the opening operation. As the top plate 12 is opened, the bolt 15 reaches the lower end of the elongated hole 14. Then, the electrical component box 11 is taken out from the opened gap.

In the above embodiment, the accumulator fixing plate 3
Since the spacer 5 is interposed between the mounting plate 31 and the mounting plate 31,
There is an advantage that the vibration transmitted from the compressor 27 to the mounting plate 31 is mitigated, and the operation parts 32a and 33a of the closing valve are not loosened by the vibration and the refrigerant pipe is not damaged. In addition, since the top plate 12 of the outdoor unit is devised in its mounting structure, there is an advantage that the internal electrical component box can be taken out from the front surface of the case 21 as it is even in a vertically and horizontally connected installation.
