Since the conventional air conditioner is configured as described above, there is a possibility that rainwater splashes on the electric components when the blower rebounds during operation. In addition, there is a problem that it is difficult to replace the electric parts because the electric parts are fixed to the partition plate when the electric parts are replaced.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has a heat exchanger room and a compressor room which are completely separated to prevent intrusion of rainwater and the like, and have a heat radiation effect of electric appliances. It is an object of the present invention to obtain a ceiling-mounted outdoor unit of an air conditioner, which is a high heat exchange unit and can easily take out an electric product from the outside of the heat exchange unit even when exchanging the electric product.

[0006]

According to the present invention, a ceiling-suspended outdoor unit for an air conditioner includes a unit case which integrally divides a heat exchange room and a compressor room, a heat exchange room and a compressor. A partition plate for partitioning the chamber and having a notch, a relay panel to which electric components are attached and which is detachably housed in a compressor room from a lateral direction; and a relay panel provided in the relay panel, wherein the relay panel is a compressor. When housed in the chamber, the notch of the partition plate protrudes toward the heat exchange chamber side and is closed, and a heat radiating part constituting a part of the partition plate is provided.

[0007]

In the ceiling-suspended outdoor unit of the air conditioner according to the present invention, the heat radiating portion of the relay panel projects and closes the cutout of the partition plate toward the heat exchange chamber, forming a part of the partition plate to prevent intrusion of rainwater and the like. To prevent. In addition, since the heat radiating portion of the relay panel is exposed to the heat exchange chamber, a high heat radiating effect can be obtained. Further, since the relay panel is detachable, it is possible to take out the electric product together with the relay panel.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a ceiling-suspended outdoor unit according to an embodiment of the present invention. In FIG. 1, 18 is an anchor bolt, 19 is a hanging tool, and the outdoor unit 1 is a nut 20.
And fixed to the ceiling. 21 is a unit case, and 34 is a cover which becomes a part of the unit case. FIG. 2 is a view showing the inside of the ceiling-suspended outdoor unit.
Distinguishes the compressor room 3 and the heat exchanger room 2 from each other. The partition plate 4 has a cutout portion 22, and an upper rail 23 is fixed above the cutout portion 22 and a lower rail 24 is fixed below the cutout portion 22 to the partition plate 4. Reference numeral 25 denotes a relay panel formed in an L-shape when viewed from above, and a vertical surface 26 on the heat exchanger chamber 2 side.
A heat radiating plate 28 having a groove 27 (engaging portion) for accommodating the upper rail 23 and the lower rail 24 of the notch 22 of the partition plate 4 is fixed to a. Vertical plane 2 on the compressor room side
Electrical components and components (not shown) that generate much heat are attached to 6b. Also, the other vertical surface 29 of the relay panel 25
An electric component such as the control board 30 is attached to the control panel. still,
Reference numeral 31 denotes a bell mouth, and the radiation fins 32 of the radiation plate 28
A notch 33 is provided so that the relay panel 25 can be passed when the relay panel 25 is put in and out. A heat exchanger 5 and a blower 6 are provided in the heat exchanger room 2, and a compressor (not shown) is provided in the compressor room 3.

Next, the operation will be described. In the above, the upper and lower grooves 27 of the heat sink 28 when the relay panel 25 is housed.
Is stored in the upper rail 23 and the lower rail 24 of the cutout portion 22 of the partition plate 4, and is slid and set, so that the heat radiating plate 28 becomes a part of the partition plate 4, and the compressor room 3 and the heat exchanger room 2 Is configured. As described above, the wind generated by the operation of the blower 6 is always applied to the radiator plate which is a part of the partition plate 28, and is cooled. In addition, at the time of maintenance service and replacement of electrical components, the unit is slid out from the front of the unit by the groove 27 of the heat sink 28 attached to the relay panel 25 and the upper rail 23 and the lower rail 24 of the partition plate 4.

In this embodiment, the relay panel 25 has an L-shape. First, the vertical surfaces 26a and 26b are cooled by the heat radiating plate 28. Therefore, components generating much heat are arranged on the vertical surface 26b. Next, since the cooling is transmitted to the other vertical surface 29 of the L-shape of the relay panel, it is desirable that the vertical surface 29 is also provided with the electrical components and the substrate close to each other. Therefore, it is desirable to use a metallic material having high heat conductivity for the relay panel.

As described above, in the above-described embodiment, the main body is provided with the heat exchanger room for housing the heat exchanger and the blower, and the compressor room for housing the compressor and the electric parts, both of which are partitioned by the partition plate. In the ceiling-suspended outdoor unit of the air conditioner, a rectangular notch cut out from the front to the rear in the partition plate, a pair of upper and lower rails formed on the upper and lower edges of the notch, and a relay, An air conditioner mounted on and fixed to a side surface of the panel and having a plurality of fins having upper and lower sliding front and rear sliding grooves which engage with the upper rail and the lower rail and which can be slidably attached and detached. The ceiling-suspended outdoor unit was explained.

In the above embodiment, the heat radiating plate is notch 2
Although the case in which the groove 27 engages with the second part is described, the engagement part may be provided between the heat radiating part and the electric component. Further, the engaging portion need not be a groove, but may be any as long as it engages so as to cover the cutout portion 22. Also, the upper and lower rails need not be rails and may have other configurations.

Further, in the above embodiment, the notch 22 is cut off at the upper left portion of the notch plate 4 as shown in FIG. 3, but the upper and lower portions are left as shown in FIG. The left portion may be cut off. In the case shown in FIGS. 3 and 4, since maintenance is performed from the left side in the figure, it is preferable to provide a cover on the left side.
