By disassembling or removing one of the fixing members, the entire electronic control device can be seen, and the electronic control unit can be exposed from the main body and the electronic control device cannot be pulled out. Service of the electronic control device can be performed, and maintenance can be facilitated.

[0007]

According to the first aspect of the present invention, a connecting wire connecting terminal and an electronic control device for controlling operation are attached to respective fixed members, and these fixed members are disassembled and united. This is a ceiling-mounted air conditioner in which a box-shaped electrical component is formed, and the electrical component is attached to the main body via one fixing member.

[0008] According to this configuration, by disassembling and removing the other fixing member that is not attached to the main body, the entire electronic control device can be seen as being attached to the main body,
A service can be provided to the electronic control device, and maintenance can be facilitated.

According to a second aspect of the present invention, in the configuration according to the first aspect, the fixing member to which the electronic control device is attached is a box-shaped power supply box having a lower surface and a surface adjacent to the lower surface opened. And a fixing member to which the connection wire connection terminal is attached is a power supply cover that covers an open portion of the power supply box and is detachable from the power supply box.

According to this structure, the entire electronic control device can be seen by disassembling and removing the power supply cover also serving as the connection wire connection terminal from the power supply box.

An embodiment of the present invention will be described below with reference to the drawings. (Embodiment 1) FIG. 1 is a cross-sectional side view of a short side of an air conditioner, and FIG. 2 is an exploded perspective view of an electrical unit.

1 and 2, below an air conditioner 2 embedded in a ceiling 1, a decorative panel 3 exposed on the surface of the ceiling 1 is fixed. The decorative panel 3 is provided with an inlet 4 and an outlet 5. An underframe (main body) 6 constituting the upper exterior of the air conditioner 2 has an opening positioned below. The cross flow fan 7 that performs the blowing action is disposed opposite to the outlet 5 side, and the heat exchanger 8 that performs heat exchange with room air is disposed opposite to the intake port 4 side. Further, a water receiving tray 9 for receiving drain water discharged from the heat exchanger 8 constitutes a lower exterior. An electrical unit 10 for operating the air conditioner 2 is disposed on the suction port 4 side.

The power supply box 11 which constitutes the electric component unit 10 has a box shape, and has a lower surface and a surface adjacent thereto, that is, two surfaces open. An electronic control board (electronic control device) 12 for controlling operation is inserted into the power supply box 11 from below. The inserted electronic control board 12
The front surface of the power supply box 11 is directed toward the open side of the power supply box 11, and is held by a claw body 13 provided on the power supply box 11 side. A substantially L-shaped power supply cover (fixing member) 14 is attached so as to cover the open portion 11A of the power supply box 11.
On a vertical surface of the power supply cover 14, a connection wire connection terminal 15 for receiving a power supply for operation or the like is provided with a connection port 1 thereof.
5A is attached downward with screws 16 or the like.

According to this embodiment, the power supply cover 14 is disassembled and removed from the power supply box 11, and the opening 11A of the power supply box 11 is opened, so that the electronic control board 12 is attached to the power supply box 11. The entire surface of the electronic control board 12 can be viewed from the suction port 4 while the user is standing. That is, the electronic control board 12 can be easily checked only by removing the power supply cover 14.

[0015]

As is apparent from the above configuration, claim 1
According to the invention described in (1), a connection wire connection terminal and an electronic control device for controlling operation are attached to respective fixing members, and these fixing members are disassembled and combined to form a box-shaped electric component. The part is attached to the main body via one of the fixing members. According to this configuration, by disassembling and removing one of the fixing members, the entire electronic control unit is viewed with the electronic control device attached to the main body. (Check), the service of the electronic control unit can be easily performed, and the maintenance can be easily performed.

According to a second aspect of the present invention, the electronic control unit is mounted on a power supply box mounted on the main body side, and the connection wire connection terminal is mounted on a power supply cover detachable from the power supply box. By disassembling and removing the power supply cover from the power supply box, the entire electronic control unit can be seen, and the power supply cover serves not only as a fixing member but also as a connection wire connection terminal. Can be.
