By engaging with the protruding piece 8 provided upright on the bottom frame 11, the switchbox main body 61 can be reliably and easily positioned at an appropriate position with respect to the casing 1, so that it can be installed in this positioned state. be.

(Example) The air conditioner shown in FIG.
The inside of a box-shaped casing 1 with
The heat exchange chamber 1a is equipped with a compressor 3.
A front plate (not shown) is installed in front of the machine room 1b, and the heat exchange room 1a is
A suction grill 13 is provided in front of the heat exchanger 2 in the heat exchange chamber 1a, while the heat exchanger 2 in the heat exchange chamber 1a
A fin 4 and a fan motor 5 are disposed at the top of the casing 1, and a blowout passage is defined at the top of the casing 1 via a partition plate 14, and a blowout grill 15 is provided in front of this blowout passage. Suction grill 1
3, the air sucked into the casing 1 is blown out from the suction grille 15.
Further, a switch box 6 for holding switches such as a switch for the compressor 3 and a switch for the fan motor 5 is housed in the machine room 1b.

This switchbox 6 is formed by a switchbox main body 61 with an open front side and a lid body 62 that closes the open front side of the main body 61.
Further, at the upper end of the switch box main body 61,
A mounting piece 61a is provided that projects upward and overlaps the front surface of the partition plate 12.

In the present invention, the switch box 6 of the air conditioner formed as described above is attached to the bottom frame 11, and as shown in FIGS. A rising piece 72 extends upward from one end of the fixing portion 71, and a rising piece 72 extends from the tip of the rising piece 72 to the horizontal body, and extends from the bottom surface 6 of the switch box body 61.
A pedestal 7 consisting of a supporting portion 73 that overlaps with the pedestal 7 is fixed, and a protruding piece 8 that protrudes upward is provided at the tip of the supporting portion 73 of this pedestal 7.
On the bottom surface 61b of the switchbox main body 61,
An engaging portion 6 consisting of a fitting hole that engages with the protruding piece 8
3, and the engaging portion 63 is engaged with the protruding piece 8, so that the switchbox main body 61 is disposed between the partition plate 12 and the bottom frame 11.

In addition, screw holes 74 and 12a are provided on the proximal side of the support portion 73 of the pedestal 7 from the engaging portion 63 and on the front surface of the partition plate 12, and screw holes 74 and 12a are provided in the bottom surface 6.
1b and the mounting piece 61a, each of the screw holes 7
4 and 12a are provided, and the switchbox main body 61 is attached to the casing 1 by tightening the mounting screws 9, 9 which are screwed into the respective screw holes 74, 12a from these insertion holes 61c, 61d. I'm trying to install it.

The lid body 62 also has a locking piece 62a that protrudes from its lower end toward the back side and overlaps the bottom surface 61b.
The locking piece 62a is provided with an engaging portion 64 consisting of a fitting hole that engages with the protruding piece 8 of the pedestal 7, while the upper end of the lid 62 is provided with a front surface of the switchbox main body 61. A mounting portion 62b that overlaps the upper end portion 61e is provided, a screw hole 61f is provided in the front upper end portion 61e, and an insertion hole 62c that matches the screw hole 61f is provided in the mounting portion 62b,
The cover body 62 is attached to the switchbox main body 61 by tightening the attachment screw 10 which is screwed into the screw hole 61f through the insertion hole 62c.

The present invention is constructed as described above. When attaching the switchbox main body 61 to the casing 1, the switchbox main body 61 is first placed in the machine room 1b of the casing 1, and the The switchbox main body 61 can be reliably positioned at an appropriate position in the casing 1 by simply fitting and engaging the joint portion 63 into the protruding piece 8 of the bottom frame 11. Therefore, the switchbox main body 61 can be easily attached to the casing 1 in this positioned state. That is, in the positioned state, the mounting piece 61a of the switchbox main body 61
are superimposed on the front end surface of the partition plate 12, and the screw hole 1 of the partition plate 12 is inserted from the insertion hole 61d of the mounting piece 61a.
Since the mounting screw 9 can be easily inserted into 2a, the switchbox main body 61 can be easily mounted. Further, even when fixing the bottom surface 61b of the switchbox main body 61, the mounting screw 9 can be easily inserted into the screw hole 74 from the insertion hole 61c of the bottom surface 61b with the switchbox main body 61 positioned. It's easy to do.

Further, the lid body 62 is attached to the switch box body 61.
When the lid 62 is attached to the lid 62, the lid 62 can be reliably positioned at an appropriate position by simply fitting and engaging the engaging portion 64 provided at the lower part of the lid 62 into the protruding piece 8. . Therefore, the lid 62 can be attached to the main body 61 in this positioned state. That is, in the positioned state, the mounting portion 62b of the lid body 62 is overlapped with the front upper end portion 61e of the main body 61, and the screw hole 61 of the front upper end portion 61e is inserted from the insertion hole 62c of the mounting portion 62b.
Since the mounting screw 10 can be easily inserted into the hole f, the lid 62 can be easily mounted.

In addition, in the embodiment described above, the bottom frame 11
Although the pedestal 7 is attached to the pedestal 7 and the protruding piece 8 is provided on the pedestal 7, the protruding piece 8 may also be provided directly on the bottom frame 11. In this case, the fourth and fifth
As shown in the figure, it is preferable to provide a substantially U-shaped cut groove in a part of the bottom frame 11 and to form the protruding piece 8 by bending the piece inside the cut groove. By doing so, there is no need to provide a special member for positioning, so the structure can be simplified and costs can be further reduced.

Further, in the above embodiment, the switch box main body 61 and the lid body 62 are provided with an engaging portion 6 consisting of a fitting hole.
3, 64, but these engaging parts 63, 64
may be formed in a concave shape as shown in FIG.

(Effects of the Invention) As described above, in the present invention, the bottom frame 11 of the casing 1 is provided with the protrusion piece 8 that protrudes upward, and the protrusion piece 8 is engaged with the bottom surface of the switchbox main body 61 whose front face is open. Since the switch box main body 61 is disposed between the partition plate 12 and the bottom frame 11 by providing an engaging portion 63 to engage the protruding piece 8, the switch box body 61 is disposed between the partition plate 12 and the bottom frame 11. When attaching the box main body 61 to the casing 1, the switch box main body 61 can be attached to the switch box main body 61 by a very simple operation of simply engaging the engaging portion 63 on the bottom surface of the switch box main body 61 with the protruding piece 8 of the bottom frame 11. It is possible to reliably and easily position it in the proper position. Therefore, it is possible to improve the efficiency of attaching the switchbox main body 61 and to reduce costs.
