[0008] (Knowledge and other information that formed the basis of this disclosure) At the time the inventors conceived of this disclosure, there was a technology in which an outdoor unit consisted of a housing and a partition plate that divided the housing into a heat exchange chamber and a machine room, and the housing had an exterior panel. However, the inventors discovered that with the conventional technology, as the size of the outdoor unit increased, the weight of the exterior panel attached to the housing increased, making it difficult to perform internal maintenance by removing the exterior panel. To solve this problem, they came to form the subject of this disclosure. Therefore, this disclosure provides an outdoor unit that allows for easy internal maintenance.

[0009] Hereinafter, embodiments will be described in detail with reference to the drawings. However, detailed descriptions may be omitted more than necessary. For example, detailed descriptions of well-known matters or redundant descriptions of substantially the same configurations may be omitted. Note that the attached drawings and the following description are provided for those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0010] In the description, the descriptions of directions such as front, back, left, right, up, and down are the same as the directions of front, back, left, right, up, and down when the outdoor unit in FIG. 1 is viewed from the front, unless otherwise specified. Also, in each figure, UP indicates the upward direction of the outdoor unit, FR indicates the forward direction, and R indicates the right direction.

Furthermore, the partition plate 25 and the third front panel 13 are fixed together by fastening members passing through the fastening holes 13b2 of the third right end folding portion 13B and the fastening holes 25b2 of the partition plate flange portion 25B.

[0056] The left end of the second front panel 12 is positioned to overlap with the fourth right end folding portion 14B of the fourth front panel 14 when viewed from the front. The front claw 12c1 of the second front panel 12 passes through the fitting hole 14c of the fourth right end folding portion 14B and engages with the fitting hole 25b1 of the partition plate flange portion 25B of the partition plate 25. This fixes the partition plate 25, the fourth front panel 14, and the second front panel 12 in place. The lateral claws 12c2 of the second front panel 12 are fixed by fitting into the fitting holes 17c of the second rear panel 17.

[0057] Figure 11 is a cross-sectional view showing the fixing structure of the second front panel 12 and the first front panel 11. The first front panel 11 is positioned so as to overlap, in a front view, the second upper folded portion 12A of the second front panel 12 and the third right folded portion 13B of the third front panel 13. The front claw 11c1 at the left end of the first front panel 11 passes through the fitting hole 13c of the third right end folding portion 13B and engages with the fitting hole 25b1 of the partition plate flange portion 25B of the partition plate 25. This fixes the partition plate 25, the third front panel 13, and the first front panel 11 in place. The lateral claws 11c2 of the first front panel 11 are fixed by fitting into the fitting holes 16c of the first rear panel 16. Furthermore, the first front panel 11 and the second front panel 12 are fixed together by passing a fastening member through the fastening hole 11b2 at the lower end of the first front panel 11 and the fastening hole 17b1 at the upper rear folded portion 17A.

[0058] Figure 12 is a cross-sectional view showing the fixing structure of the top plate 20 and the first upper folded portion 11A. The top plate 20 is positioned to cover the first upper folded portion 11A, the third upper folded portion 13A, the first rear upper folded portion 16A, and the outdoor heat exchanger 31. The folded portion 20b of the top plate 20 is positioned to be on the outside of the housing 5, relative to the first upper folded portion 11A, the third upper folded portion 13A, the first rear upper folded portion 16A, and the outdoor heat exchanger 31. The top plate 20 is fixed by fastening members passing through the fastening holes 20b1 in the folded portion 20b and the fastening holes in the first upper folded portion 11A, the third upper folded portion 13A, and the first rear upper folded portion 16A, which are located at positions corresponding to each of the folded portions 20b.

[0059] [1-2. Effects, etc.] In this embodiment, first, the fourth front panel 14 is placed on the housing 5, and the third front panel 13 is placed on top of the fourth upper end folding portion 14A of the fourth front panel 14 such that the third front panel 13 is on the outside. Next, the second front panel 12 is placed on top of the fourth right end folding portion 14B such that the second front panel 12 is on the outside. Next, the first front panel 11 is placed on top of the third right end folding portion 13B and the second upper end folding portion 12A such that the first front panel 11 is on the outside. Finally, the top panel 20 is placed so that the folded portion 20b of the top panel 20 is on the outside of the first upper end folding portion 11A, the third upper end folding portion 13A, and the first rear upper end folding portion 16A.

[0060] Therefore, unlike conventional technology, there is no need to remove heavy, large exterior panels. By removing the front panels sequentially starting from the first front panel, the front panels can be separated and removed, making maintenance easier.

[0061] Furthermore, by arranging the electrical equipment 41 according to the frequency of maintenance, maintenance can be performed without removing all the exterior panels.
