Description

[Detailed description of the invention] [Industrial application field] This invention relates to an outdoor unit of an air conditioner.

[Conventional technology]

FIG. 5 is a partially cutaway front view of the outdoor unit of a conventional air conditioner disclosed in, for example, Japanese Utility Model Application No. 61-74077. In the figure, 1 is an outdoor unit, 2 is a board of this outdoor unit, and 3 is a partition plate for dividing the blower room 4 and the compressor room 5. 6 is a blower placed in the blower room 4, 7 is the compressor room 5
The compressor 16 installed inside the air blower room 4 is an electrical parts box mounted on the board 2 from the partition plate 3, and the back and bottom surfaces of the electrical parts box 16 are open, and the back opening is 17 is fitted into an opening formed in the partition plate 3, and a flange 19 formed at the periphery of the opening 18 is engaged with the inner wall edge of the opening in the partition plate 3 on the side of the compressor chamber 5. The lower end of 16 is fixed to the substrate by tightening a flange 20 provided on the lower edge with screws 21. Further, an exhaust port 23 is formed on the upper wall 22 of the electrical parts box 16, and a duct 24 is attached to the upper part of the electrical parts box so as to cover the upper part of this exhaust port 23. The blower room 4 and the compressor room 5 are communicated through the electrical parts box 16. An electrical component stand 9 is installed on the board 2 located in the electrical component box 16,
A heat-generating electrical component 8 is fixed onto this electrical component stand 9 with a mounting screw 10.

Next, the operation will be explained. When the blower 6 in the blower room 4 of the outdoor unit 1 rotates, the outside air sucked into the compressor room flows from the compressor room 5 to the rear opening 17 of the electrical parts box 16 and to the The air passes through the parts box 16 and further flows into the blower chamber 4 through the exhaust port 23 and the duct 24, thereby cooling the electrical parts 8.

[Problem that the invention attempts to solve]

Conventional outdoor units are constructed as described above, and it is necessary to assemble the electrical parts box before attaching the partition plate, making it difficult to install the partition plate.Also, since the electrical parts box is screwed to the board, screws are required. The tip of the unit protrudes outward from the unit, and there is a risk of getting your fingers caught and getting injured when assembling the outdoor unit or during maintenance and inspection.

This idea was created to solve the problems mentioned above, and it eliminates the need for mounting screws for the electrical component box, eliminating any damage caused by the tips of the screws, and making it easier to install the partition plate. The purpose is to provide an outdoor unit for an air conditioner.

[Means for solving problems]

In the outdoor unit according to this invention, a part of the bell mouth is formed to cover the electrical components provided at the bottom of the partition plate, an electrical component box is integrally provided, and the electrical components are located on the compressor room side. This is what I did.

In another embodiment of the present invention, not only the electric parts at the bottom of the partition plate but also the partition plate above it are eliminated, and the bell mouth is formed by further elongating it.

[Effect]

In the outdoor unit of this invention, the electrical parts box is integrally formed with the bell mouth, so there is no need to provide screws for mounting the electrical parts box on the board, the danger of screw tips can be prevented, and it is easy to assemble the partition plate. Can be done.

[Example of idea]

Hereinafter, embodiments of this invention will be described with reference to the drawings. In FIGS. 1 and 2, 1 is an outdoor unit of an air conditioner, 2 is a board of this outdoor unit 1,
3 is a partition plate that partitions the blower room 4 and the compressor room 5; 6 is the blower installed in the blower room 4; 7 is the compressor installed in the compressor room 5; 8 is the lower part of the partition plate 3. A heat-generating electrical component is located on the electrical component stand 9 installed on the board 2 with a mounting screw 10.
Fixed by 12 is a convex portion formed by extending a part of the bell mouth 11 to cover the electrical components;
13 is a lower rib that separates the convex portion provided on the bell mouth 8 from the blower chamber 4, and 14 is an upper rib that separates the convex portion provided on the bell mouth 8 from the blower chamber 4. 1
5 is an exhaust port provided in the partition plate 3. The operation of the outdoor unit of one embodiment configured as described above will be explained. When the blower 6 in the blower room 4 rotates, the outside air sucked into the compressor room 5 flows through the compressor room 5 and the bell mouth 11 as shown by the arrow in FIG.
Air flows from around the electrical component 8 of the convex portion 12 into the blower chamber 4 through the exhaust port 15 of the partition plate 3, thereby cooling the electrical component 8. In addition, during assembly, the bell mouth 11 is provided with the protrusions 12 and ribs 13 and 14 to cover the electrical components 8, so when the partition plate 3 is installed, the bell mouth 11 is not present and the partition plate 3 can be easily attached to the board. 2, the number of parts can be reduced, there is no need to use screws for fixing the electrical component box at the bottom of the board 2, there is no protruding part at the bottom of the board 2, it is safe, and it is easy to work and can reduce costs. It is.

3 and 4 show other embodiments of this invention. In this embodiment, the convex portion 12 of the bell mouth 11 is
Extend it to the top of the partition plate 3 and attach the ribs 13 and 14.
is provided to partition the compressor room 5 and the blower room 4.

As mentioned above, the convex part 12 rib 1 of the bell mouth 11
3 and 14, the same effect as the embodiment of this invention shown in FIGS. 1 and 2 can be obtained, and furthermore, the shape of the partition plate 3 is simplified, workability is improved, and it is advantageous in terms of cost. become.

[Effect of idea]

As described above, according to this invention, the electrical parts box is integrated into the bell mouth, which improves the ease of assembling the partition plate, and there are no protruding parts such as screws on the bottom of the board, which prevents damage to hands and fingers. This has the effect of enabling safe work, reducing the number of parts, improving work efficiency, and reducing costs.
