Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 is a perspective view of a heat exchange unit 1 of the present invention through which the exterior panel 2 is seen, and FIG. 2 is an exploded perspective view of the heat exchange unit 1. The heat exchange unit 1 of the embodiment is an outdoor unit of a separation type air conditioner, and a rotary type compressor 4 as a refrigerating device, a condenser 6, a fan 7 for condenser, a receiver 8 and the like are provided on a bottom plate 3. Attached, bottom plate 3
A rear panel 9 is provided upright on the rear edge of the rear edge. The exterior panel 2 has a substantially inverted L-shaped cross section having a front surface and a top surface,
It is fixed to the front edge of the bottom plate 3 and the rear panel 9 to cover the refrigeration equipment. The left side of the heat exchange unit 1 is closed by a side panel 11, and an outlet grill 12 is attached to the front surface of the exterior panel 2. Further, a mounting plate 13 is erected on the right side of the bottom plate 3, and the valves 14 are vertically mounted on the mounting plate 13.

The right side of the heat exchange unit 1 is closed by an upper panel 16 as a first panel and a lower panel 17 as a second panel. The lower panel 17 is located below the upper panel 16 and is fixed to the exterior panel 2 and the back panel 9. Inverted U on the bottom of the lower panel 17
A V-shaped cutout portion 18 is formed, and the valves 14 and 14 are exposed to the outside from the cutout portion 18. Further, a projecting piece 19 is attached to the upper edge of the lower panel 17, and extends obliquely upward to the outside of the heat exchange unit 1. The protruding piece 19 has a mounting hole 2 which serves as a guide for electric wiring described later.
1 is drilled in three places.

The upper panel 16 is located above the lower panel 17, and is similarly fixed to the exterior panel 2 and the rear panel 9. Further, the upper panel 16 can be removed even when the lower panel 17 is attached. This upper panel 16
A cover part 22 is formed in the lower part of the cover part 22. The cover part 22 bulges outside the heat exchange unit 1 so as to cover the protruding piece 19 of the lower panel 17 from above. The upper and lower panels 16 and 17 form one side wall of the heat exchange unit 1.

A terminal plate 23 as a fixture is provided in the heat exchange unit 1 corresponding to the inside of the upper panel 16. As shown in FIGS. 3 and 4, a plurality of electrical components 24 to 34 (these are collectively referred to as 35) are collectively attached to the attachment surface 23A of the terminal plate 23, and the terminal plate 23 is also attached. A pressure switch 36, which is also an electrical component, is attached to the lower edge. Reference numeral 37 is a top cover of the terminal board 23. Of the electric components 35, 24 is the compressor 4
Is a magnet switch, 25 is a fuse, 28 is a connection terminal for electric wiring to be described later, 29 is an operation switch, and 30 is a reverse-phase alarm lamp. As shown in FIGS. 1 and 2, the terminal plate 23 is built in the heat exchange unit 1 so as to correspond to the inside of the upper panel 16, and the mounting surface 23A faces the upper panel 16 side of the exterior panel 2. Front and back panels 9
It is fixed across. As a result, the electrical component 35 and the pressure switch 36 are arranged inside the heat exchange unit 1 so as to face the inside of the upper panel 16. Further, in this state, in the diagonally lower vicinity of the terminal board 23,
The protruding piece 19 of the lower panel 17 is located.

Next, as shown in FIG. 2, the electric wiring 39 drawn into the heat exchange unit 1 has a conduit 41 on the outer circumference.
The conduit 41 is covered with a fitting 4
2 is provided, and a screw portion 43 is formed on the tip side of the fixture 42.

The heat exchange unit 1 having the above structure is
It is shipped with the upper and lower panels 16 and 17 attached. At this time, the heat exchanging unit 1 can be carried by holding the protruding piece 19 of the lower panel 17 with a hand. Then, when the electric wiring 39 is drawn in and connected to the connection terminal 28 of the terminal board 23, only the upper panel 16 is removed and the upper half of the side wall of the heat exchange unit 1 is opened. After that, the fitting 42 of the conduit 41 is inserted into the fitting hole 21 of the protruding piece 19 of the lower panel 17 from below, and a nut (not shown) is screwed to fix the fitting 42 to the protruding piece 19. In this state, the electric wiring 39 is located in the vicinity of the connection terminal 28 of the terminal board 23. Therefore, by inserting a hand or a tool through the opening above the lower panel 17, the electric wiring 39 is extremely easily connected to the connection terminal 28. be able to. After that, the upper panel 16 is attached again to cover the electric wiring 39 and the terminal board 23.

The operation switch 2 of the electric component 35 is also provided.
9 is operated, the reverse-phase alarm lamp 30 is confirmed, the fuse 25 is replaced, or the pressure switch 36 is adjusted. Similarly, only the upper panel 16 is removed to remove the heat exchange unit 1. Open the upper half of the side wall. In this state, the mounting surface 23A of the terminal plate 23 can be seen from the front through the opening as shown in FIG. That is, since the electrical component 35 attached to the terminal plate 23 appears toward the opening above the lower panel 17 only by removing the upper panel 16, the electrical component 35 is inserted by inserting a hand or a tool through the opening. It is possible to easily perform the operation, confirmation, setting, replacement, etc. After that, the upper panel 16 is attached again to cover the electric wiring 39 and the terminal board 23.

In particular, since the electric wiring 39 is drawn from the lower panel 17 and does not interfere with the upper panel 16 at all, when operating the electrical components 35 of the terminal board 23 as described above, There is no need to remove the electrical wiring 39,
The operation and confirmation can be performed smoothly.

In the embodiment, the terminal plate 23 as a fixing tool
Although it is configured by a plate-shaped one, the invention is not limited to this and may be configured by a box-shaped electrical equipment box. Further, in the embodiment, the side wall of the heat exchange unit 1 is separated into the upper and lower panels 16 and 17, but they may be separated in the left and right directions. Furthermore, although the present invention is applied to the outdoor unit of the separation type air conditioner in the embodiments, the present invention is not limited to this, and the present invention is also effective to the outdoor unit of a prefabricated refrigerator, for example.

[0016]

As described in detail above, according to the present invention, since the side wall of the heat exchange unit is composed of the first and second panels, the work can be performed by removing only the upper panel when connecting the electric wiring. A large opening is provided for easy connection work. Also, if the first panel is removed, electrical components will appear in the direction of the opening, and at that time there is no need to remove electrical wiring, etc.
The operation and setting or maintenance work of the electrical components can be carried out extremely smoothly and easily.
