Here, the entire shape of the shut-off valve mounting member 50 is S-shaped by the connecting portion 53.

(4) Features of the outdoor unit The outdoor unit 2 provided with the closing valve mounting member 50 of the present embodiment has the following features.

<A>
Here, as described above, the closing valve mounting member 50 supports the closing valve 13 and the compressor opposing portion 51 that crosses the front side of the compressor 7 when the casing 40 is viewed from the front. 52, and a connecting portion 53 that connects between the compressor facing portion 51 and the closing valve support portion 52 so that a vertical step is formed between the compressor facing portion 51 and the closing valve support portion 52. Have.

  For this reason, here, the connecting portion 53 crosses the front side of the compressor 7 when performing various operations on the compressor 7 (electrical connection from the front of the compressor 7 to the terminal 71 and piping connection to the discharge nozzle 72). It is possible to arrange the compressor facing portion 51 so as to be in a vertical position that does not interfere with the work. Specifically, when the connection portion 53 is viewed from the front, the compressor facing portion 51 is electrically connected. A step in the vertical direction is formed so as not to overlap the connection terminal 71 and the pipe connection discharge nozzle 72.

  Thereby, here, the compressor 7 and the shut-off valves 13 and 14 are arranged in the casing 40, so that the casing 50 crosses the front of the compressor 7 when viewed from a predetermined direction (here, the front side). In the outdoor unit 2 that is disposed and provided with the closing valve mounting member 50 that supports the closing valves 13 and 14, a working space from the front of the compressor 7 can be secured. That is, when the electrical connection work to the terminal 71 and the pipe connection work to the discharge nozzle 72 are performed, the compressor facing portion 51 that crosses the front side of the compressor 7 is disposed so as to be in a vertical position that does not interfere with the work. be able to.

  At this time, the vertical position of the closing valve support 52 is also set to the same vertical position as that of the compressor facing portion 51, so that the same shape as that of the conventional art without any step (a straight line extending horizontally) can be considered. It is done. However, since it is necessary to change the vertical position of the shut-off valves 13 and 14 in this way, the length and the bent shape of the refrigerant communication tubes 4 and 5 that are drawn into and connected to the casing 40 are different from those of the conventional one. Thus, when the outdoor unit 2 is updated, the refrigerant communication pipes 4 and 5 cannot be used as they are, and the work of adjusting the shape and length of the refrigerant communication pipes 4 and 5 is required. become. On the other hand, here, by adopting the connection part 53 as described above, the vertical position of the closing valve support part 52 and thus the closing valves 13 and 14 can be maintained at the same position as in the prior art. It is possible to prevent such inconvenience.

<B>
Here, as described above, the connecting portion 53 forms a step in the vertical direction that makes the vertical position of the compressor facing portion 51 lower than the vertical position of the closing valve support portion 52.

  For this reason, since the level | step difference which can form a working space in the upper side of the compressor opposing part 51 can be formed here, it can access to the work object part of the compressor 7 from diagonally upward. Thus, workability can be improved.

<C>
Here, as described above, the closing valve mounting member 50 is a member in which three portions (the compressor facing portion 51, the closing valve support portion 52, and the connection portion 53) are integrally formed.

  For this reason, the number of parts required for the support structure of the shut-off valves 13 and 14 can be reduced here, and it is not necessary to attach each part, and when the shut-off valve mounting member 50 is attached to the outdoor unit 2. Workability can be improved.

<D>
Here, as described above, the connecting portion 53 forms a step in the vertical direction that makes the overall shape of the closing valve mounting member 50 an S shape.

  For this reason, here, as shown in FIG. 7, when the shut-off valve mounting member 50 is molded from a plate-shaped material with a mold, the material is wasted as much as possible except for the hatched portions in FIG. Without this, the plurality of closing valve mounting members 50 can be molded.

  Thereby, when manufacturing the closing valve attachment member 50 from a plate-shaped raw material, the development area in a metal mold | die can be made small and it can make it easy to mass-produce.

(5) Modification <A>
In the above embodiment, with respect to the configuration in which the terminal 71 for electrical connection and the discharge nozzle 72 for pipe connection are provided at the top of the compressor 7, the vertical position of the compressor facing portion 51 is set to the closing valve support portion 52. Although the shut-off valve mounting member 50 having the connecting portion 53 that forms a step in the vertical direction that is lower than the vertical position is adopted, the present invention is not limited to this.

  For example, as shown in FIG. 8, also when the discharge nozzle 72 is provided below the top of the compressor 7, the closing valve mounting member 50 similar to the above embodiment, that is, the compressor facing portion 51. A closing valve mounting member 50 having a connecting portion 53 that forms a step in the vertical direction that lowers the vertical direction position of the vertical direction than the vertical position of the closing valve support 52 may be employed. Even in this case, the compressor facing portion 51 can be prevented from overlapping the discharge nozzle 72 for pipe connection when the casing 40 is viewed from the front.

  Further, as shown in FIG. 9, conversely to the above embodiment, a connecting portion 53 that forms a step in the vertical direction that makes the vertical position of the compressor facing portion 51 higher than the vertical position of the closing valve support portion 52. You may employ | adopt the closing valve attachment member 50 which has these. Even in this case, the compressor facing portion 51 can be prevented from overlapping the discharge nozzle 72 for pipe connection when the casing 40 is viewed from the front.

<B>
In the said embodiment, although the example which applied this invention to the outdoor unit 2 of a trunk type structure was demonstrated, it is not limited to this.

  For example, in other types of outdoor units such as an upper blow type structure in which an outdoor fan is disposed on the top surface side of the casing, a compressor and a shut-off valve are disposed in the casing, and the casing is viewed from a predetermined direction.
