In this state, if a hand is inserted from the open part of the main body casing X1, the hand can reach the handle portion 4a provided with the communication hole β, and the wiring 6 is connected to the main body from the communication hole β. It can be pulled into the inside of the housing X1. In addition, a terminal plate 8 to which the wiring 6 is to be connected is provided inside the main body casing X1 so as to face the open position when the front panel portion 13 is removed. When the wiring drawn through the communication hole β is connected to the terminal plate 8, the outdoor unit A can be operated. Thereafter, the front panel portion 13 is again attached to the main body casing X1, and the communication hole β in the handle portion 4a is filled with putty or the like.
As described above, according to the present embodiment, the wiring 6 can be drawn into the main body casing X1 through the communication hole β provided in the handle portion 4a. That is, it is possible to form a lead-in port for the wiring 6 in the handle part itself for placing a hand during a transport operation, and the shape of the main body casing X1 is complicated compared to the case where they are provided separately. An increase in the size of the main body casing X1 is prevented. Specifically, the umbrella part 7 for preventing raindrops in the space 7a and the cover 4d (see FIG. 7) of the handle part 4a, which are the conventional example, can be used together, and the number of parts can be reduced. Moreover, since it is not necessary to provide the space 7a again, the appearance can be refreshed. In addition, considering the construction procedure, it is normal to transport the outdoor unit using the handle to install the outdoor unit at a predetermined location, and then perform piping and wiring processing after the installation. Even if the wiring protrudes, the handle is not used after installation, so there is no problem. Further, even when moving or moving the location of the outdoor unit, since the outdoor unit is transported after the normal piping and wiring are removed, the jumped-out wiring does not get in the way.

In the above-described embodiment, the example in which the communication hole β is provided in the handle portion from the beginning is disclosed, but the present invention is not limited to this.

For example, in the handle portion 4c shown in FIG. 9, the periphery of the removal target portion γ that is the target for forming the communication hole β is surrounded by a perforated cut (an example of an intermittent cut). By cutting the periphery of the removal target portion γ with a cutter knife or the like along such a cut, the removal target portion can be easily removed. The communication hole β (see FIG. 7) can be formed.
As the removal target portion, in addition to a portion where intermittent notches are formed around, a portion surrounded by a thin portion, a portion surrounded by a soft member, and the like can be considered. Furthermore, a portion formed thinner than the surrounding, a portion formed of a member softer than the surrounding, and the like are also conceivable. The part to be removed does not have to be removed completely, and a part thereof may be removed as long as the area necessary for the wiring 6 to pass through can be secured.

The handle portion 4a provided with the communication hole β may be provided in any part of the main body housing. However, in order not to impair the aesthetics of the outdoor unit, it is also formed on the outer wall of a normal building as in the embodiment. It is considered desirable to be provided on the exhaust rear surface 3d that is considered to be opposed (the rear surface of the side surface provided with an exhaust port for exhausting outdoor air).
Further, when the wiring installed over the ground is drawn into the inside of the main body casing, the handle portion 4a provided with the communication hole β is not particularly illustrated, but the side surface of the main body casing is not illustrated. It is desirable to provide it in the vicinity of the lower side. As a result, the number of exposed portions of the wiring around the main body casing is reduced, so that the appearance of the outdoor unit is not impaired, and the possibility of disconnection of the wiring can be suppressed.
On the other hand, in the case where the wiring that hangs down along the wall of the building and is led to the outdoor unit is drawn into the main body housing, the handle portion 4a is provided in the vicinity of the upper side of the side surface of the main body housing. It is desirable to keep it.
Moreover, the said handle part is a member independent of the main body housing | casing of an outdoor unit, and the thing which can be removed in the side surface of the said main body housing | casing may be sufficient.
