As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the summary of invention.

(A)
In the above embodiment, as illustrated in FIG. 4, the example in which the electrical component unit 50 includes the wiring guide member 53 has been described. However, the present invention is not limited to this.

  For example, instead of the wiring guide member 53, as shown in FIGS. 7 and 8, the electrical component unit 50 may include a first surface member 54a and a second surface member 54b. More specifically, it is as follows.

  The first surface member 54 a extends from the end portion on the right side surface of the unit casing 2 in the second plate member 52 to the back surface side.

  The 2nd surface member 54b is extended from the edge part of the back side of the 1st surface member 54a to the support part 23c.

  A first wiring space S1 is formed between the first surface member 54a and the second surface member 54b to store the wire harness 52b extending from the control P plate 52a along the wiring path A.

  Here, in plan view, the second plate-like member 52 and the first surface member 54a are arranged such that an angle β (see FIG. 8) formed by each other is an acute angle. Further, the first surface member 54a and the second surface member 54b are also arranged such that the angle Γ (see FIG. 8) formed by each other is an acute angle.

  Thereby, in the plan view, the wire harness 52b can be pushed into the first wiring space S1 formed in a substantially triangular shape and stored along the wiring path A.

  The first surface member 54a and the second surface member 54b may be formed by press working or the like on the right side surface side of the unit casing 2 in the second plate member 52. Moreover, you may use separately the guide member which has the 1st surface member 54a and the 2nd surface member 54b.

  Also in this case, the same effect as the electrical component unit 50 according to the above embodiment can be obtained.

  Also in this case, the same effect as the electrical component unit 50 according to the above embodiment can be obtained.

  However, in this case, since it becomes difficult to push the wire harness 52b to the back side of the second wiring space S2, the angle α formed between the third surface member 53a and the second plate-like member 52 is the same as in the above embodiment. It is more preferable to join so as to be about 90 °.

(F)
In the embodiment described above, in the electrical component unit 50, the third surface member 53a and the second plate-like member 52 have been described with an example in which they are joined by spot welding. However, the present invention is not limited to this.

  For example, the third surface member 53a and the second plate-like member 52 may be joined by screwing.

  Also in this case, the same effect as the electrical component unit 50 according to the above embodiment can be obtained.

(G)
In the above embodiment, an example in which the electrical component unit 50 is provided in the outdoor unit 1 has been described. However, the present invention is not limited to this.

  For example, the electrical component unit 50 may be provided in an indoor unit of the air conditioner.

  Also in this case, the effect similar to that of the electrical component unit 50 according to the above embodiment can be obtained in the indoor unit of the air conditioner.

(H)
In the above-described embodiment, the example in which the wiring guide member 53 is joined to the second plate-like member 52 by spot welding in the electrical component unit 50 has been described. However, the present invention is not limited to this.

  For example, the second plate-like member 52 and the wiring guide member 53 may be integrally molded and used as one part from the beginning.

  In this case, the trouble of joining the second plate-like member 52 and the wiring guide member 53 by spot welding can be saved.

  However, in this case, since the second plate-like member 52 and the wiring guide member 53 are integrally formed, the manufacturing cost of the electrical component unit 50 may increase. Therefore, in the electrical component unit 50, it is more preferable to join the wiring guide member 53 to the second plate member 52 by spot welding.

(I)
In the above-described embodiment, as illustrated in FIG. 4, in the outdoor unit 1, the electrical component unit 50 has been described with an example being supported by the support portion 23 c provided on the right side surface of the unit casing 2. However, the present invention is not limited to this.

  For example, when the electrical component unit 50 is disposed on the left side of the outdoor unit 1, a support portion may be provided on the left side of the unit casing 2 to support the electrical component unit 50.

  Also in this case, the same effect as the electrical component unit 50 according to the above embodiment can be obtained.

(J)
In the said embodiment, as shown in FIG. 4, in the outdoor unit 1, the electrical component unit 50 demonstrated and demonstrated the example arrange | positioned in the upper part of machine room SP2. However, the present invention is not limited to this.

  For example, the electrical component unit 50 may be disposed in the blower room SP1 in accordance with the layout of the outdoor unit 1. Moreover, you may arrange | position the electrical component unit 50 so that fan room SP1 and machine room SP2 may be straddled.

  Also in this case, the same effect as the electrical component unit 50 according to the above embodiment can be obtained.

  Since the electrical component unit of the present invention has an effect of improving the workability of the assembly work of the outdoor unit, it can be widely applied to the electrical component unit and the outdoor unit of the air conditioner including the electrical unit.
