Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outdoor unit for an air conditioner having a structure for mounting a closing valve of a refrigerant system.

[0002]

2. Description of the Related Art In a structure for mounting a refrigerant closing valve in an outdoor unit of an air conditioner, it is necessary to sufficiently support the torque applied when opening and closing the valve. Therefore, the mounting plate of the closing valve is attached to a side plate of an outdoor unit case. I was trying to fix it. However, this structure has a drawback that workability such as inspection during piping and opening / closing of a valve is deteriorated by the side plate.

Therefore, as a conventional example devised to solve such a drawback, for example, a mounting structure described in Japanese Utility Model Laid-Open No. 4-95229 can be cited. An outdoor unit of an air conditioner having this mounting structure is, as shown in FIG.
The bottom plate 1 of the chamber 10 is divided into the chamber 10 and the compressor 6 and the fixed base 2 in the chamber 10 which is partitioned by the partition plate 4 in the case 9.
The accumulator 5 having a fixed lower end is housed therein, and the other chamber 11 houses a heat exchanger 26 and a fan (not shown). The base end 34a of the L-shaped accumulator fixing plate 34 including the accumulator mounting plate 31, the first assembly plate 32, and the second assembly plate 33 is the heat exchanger 2 described above.
The accumulator mounting plate 31 is fixed to the end 27 of the accumulator 6 and is fixed to the outer circumference of the accumulator 5. Further, the tip 3 of the accumulator fixing plate 34
Mounting plate 35 for connecting 4b and the side edge 4a of the partition plate 4
The closing valves 21 and 22 are mounted on the mounting plate 35. In the figure, 25 is another accumulator, and 30 is a side plate of the case.

With the above-described shut-off valve mounting structure,
The torque applied to the operating portions 23 and 24 of the closing valves 21 and 22 when the valves are opened and closed is determined by the mounting plate 35 and the accumulator fixing plate 3.
4, it is supported by the partition plate 4, the heat exchanger 26, and the bottom plate 1 via the fixed base 2. Moreover, in this state, case 9
Since it is not necessary to attach the side plate 30 of the above, the workability such as assembly is improved.

Further, the tip 3 of the accumulator fixing plate 34
The vibration transmitted from the compressor 6 to the mounting plate 35 via the accumulator 5 is alleviated by providing a vibration-proof rubber (not shown) between the 4b and the end portion 35a of the mounting plate 35. This avoids loosening 23 and 24 and damaging the piping.

[0006]

However, in the above-mentioned conventional example, the mounting structure of the closing valve is the fixed base 2, the mounting plate 35,
And an accumulator fixing plate 34, and the accumulator fixing plate 34 further includes a first assembly plate 32 and a second assembling plate.
Since the assembly plate 33 and the accumulator mounting plate 31 are used, there is a drawback that the number of parts is large and the assembly is complicated.

Further, since the place where the vibration proof rubber is provided is a place where torque is applied when the valve is opened and closed, there is a trade-off between securing strength for supporting the torque and the vibration proof effect, and it is difficult to achieve both of them. There was also.

The present invention has been made to solve the drawbacks of the above-mentioned conventional example, and the first object thereof is the advantage of the prior art that workability is good while reliably supporting the torque when the valve is opened and closed. It is an object of the present invention to provide an outdoor unit for an air conditioner having a closing valve mounting structure that can reduce the number of parts compared with the conventional one without losing the above. A second object of the present invention is to provide an outdoor unit for an air conditioner having a closing valve mounting structure that is excellent in vibration isolation while reliably supporting torque.

[0009]

Therefore, in the outdoor unit for an air conditioner according to a first aspect of the present invention, the air having the compressor 6 and the accumulator 5 housed in the one chamber 10 which is provided by partitioning the inside of the case 9 with the partition plate 4 is provided. In the outdoor unit of the harmony machine, the one room 10
Fixed base 2 interposed between the bottom plate 1 and the lower end of the accumulator 5 and fixing the accumulator 5 to the bottom plate 1, and the side edge 4 a of the fixed base 2 and the partition plate 4.

It is characterized in that it comprises a mounting plate 3 for connecting the side edges 4a of the above, and the respective closing valves 21, 22 are mounted on this mounting plate 3.

Further, the outdoor unit of the air conditioner according to claim 3 is
A vibration isolating member 8 is interposed between the fixed base 2 and the lower end of the accumulator 5.

[0012]

In the outdoor unit for an air conditioner according to claim 1, the side edge 4a of the partition plate 4 and the fixing base 2 for fixing the accumulator 5 to the bottom plate 1 are connected by the connecting member 12, and the connecting member 12 is also connected. The closing valves 21 and 22 of the refrigerant system are attached to the. Therefore, while maintaining the good workability of the prior art, the torque at the time of opening / closing the valve can be reliably supported by the partition plate 4, the fixing base 2 and the bottom plate 1, and the mounting structure is the same as the connecting member 12 described above. Since the fixed base 2 is used, the number of parts can be reduced as compared with the conventional case.

Further, in the outdoor unit of the air conditioner according to claim 2,
The connecting member 12 includes a stay 7 having one end 7a fixed to the fixed base 2, and a mounting plate 3 connecting the other end 7b of the stay 7 and the side edge 4a of the partition plate 4. There is. Therefore, while maintaining the advantages of the prior art, the number of parts of the mounting structure is reduced as compared with the conventional one, and each member,
