Therefore, according to the above-described embodiment, the control unit 13 can be slid by the slide mechanism unit 33, and the first layer 31A can be swung by the hinge unit 35. Further, the stopper portion 34 can prevent the control portion 13 from sliding too much. Therefore, the operator can easily access the second layer 31B by sliding the control unit 13 and then swinging the first layer 31A. Furthermore, the space in the housing | casing part 11 required in order that an operator may perform the maintenance operation | work etc. of the 2nd layer 31B can be reduced. As a result, it is possible to reduce the burden on the operator and to prevent the outdoor unit 10 from becoming large.

Further, since the hinge portion 35 is disposed outside the end portion 41ta outside the guide portion 41, the first layer 31A is shaken outside the rail portion 42 when the control portion 13 is slid to the outermost side. Can be moved. As a result, the first layer 31A can be swung as much as possible at a position outside the housing part 11, so that, for example, the degree of freedom of arrangement of devices around the control chamber 14 can be improved.

Further, when the control unit 13 is slid, even if the guide unit 41 is displaced in the width direction of the rail unit 42, the pressing force from the guide unit 41 can be released along the inclination of the side wall 42b. Therefore, the sliding resistance between the guide part 41 and the side wall 42b can be reduced, and the control part 13 can be smoothly slid with less force.

Furthermore, the guide part 41 includes a leg part 41a extending downward from the control part 13, and a guide main body part 41b extending horizontally from the lower edge of the leg part 41a and accommodated in the rail part 42, thereby providing a guide. It can suppress that the shape of the part 41 becomes complicated.
Moreover, the stopper part 34 regulates the slide of the control part 13 in the position which protruded only L / 2 to L / 3 from the edge 16b of the housing | casing part 11 to the width direction Db of the housing | casing part 11. FIG. Therefore, the space required for the swing of the first layer 31 A can be reduced inside the housing unit 11. As a result, it can suppress that the housing | casing part 11 enlarges.

Furthermore, when there is no need to perform maintenance or the like on the control unit 13, the control unit 13 can be fastened to the housing unit 11 by the fastening unit 51. Therefore, unintentional sliding of the control casing 32 with respect to the casing 11 can be suppressed.

The present invention is not limited to the configuration of the above-described embodiment, and the design can be changed without departing from the gist thereof.
For example, in the above-described embodiment, the case where the slide mechanism unit 33 supports the control housing unit 32 so as to be slidable with respect to the floor surface (base unit 16) of the control chamber 14 has been described. What is necessary is just to be slidable with respect to the housing | casing part 11, and it is not restricted to the case where the control housing | casing part 32 is supported with respect to the base part 16 so that sliding is possible. Further, the slide mechanism 33 is not limited to the guide 41 and the rail 42 illustrated in the above-described embodiment.

In the above-described embodiment, the case where the three fastening portions 51 from the first fastening portion 51A to the third fastening portion 51C are provided has been described. However, the fastening part 51 is not limited to three. The number of the fastening portions 51 may be set as appropriate as long as the sliding of the control housing portion 32 can be regulated with respect to the housing portion 11.

Further, in the above-described embodiment, the case where the first layer 31A is the control layer and the second layer 31B is the inverter layer has been described. However, the present invention is not limited to this configuration.
Moreover, although the case where the control part 13 has from the 1st layer 31A to the 3rd layer 31C was illustrated, the control part 13 should just have the 1st layer 31A and the 2nd layer 31B at least.

Furthermore, the case where the control chamber 14 in the above-described embodiment is disposed in the vicinity of the corner portion of the first side Da1 in the length direction Da of the casing portion 11 has been described. However, the arrangement of the control room 14 is not limited to the arrangement of the above-described embodiment. For example, the machine chamber 15 may be disposed on both sides of the control chamber 14 in the length direction Da of the casing 11.

In the above-described embodiment, the case where the rail portion 42 has the inclined wall has been described. However, the pair of

side walls

42a and 42b of the rail portion 42 may be formed to extend perpendicularly to the bottom wall 42c. .
