Description
- The present disclosure relates to an outdoor unit for an air-conditioning apparatus, in which the outdoor unit includes a machine-chamber front panel forming a part of an outer box.
- There is conventionally an outdoor unit for an air-conditioning apparatus, in which the outdoor unit includes a machine-chamber front panel forming a part of an outer box (for example, see Patent Literature 1). The machine-chamber front panel disclosed in
Patent Literature 1 is designed to be removable from the outer box in consideration of serviceability. However, when screw hole positions of the machine-chamber front panel are aligned with each other to screw the machine-chamber front panel to a top panel, the machine-chamber front panel is displaced downward by its own weight. This makes it difficult to align the screw hole positions with each other. Thus,Patent Literature 1 has a structure in consideration of workability, in which the top panel and the machine-chamber front panel are both provided with a temporary fixing portion at which the top panel and the machine-chamber front panel can be temporarily fixed to align their screw hole positions with each other. - Patent Literature 1: Japanese Unexamined Patent Application Publication No. 2012-220127

In the mounted state of the machine-chamber front panel 31 to thetop panel 20, the protrudingportion 40 a and the recessedportion 40 c of the machine-chamber front panel 31 are positioned inside the front surface of thetop panel 20. That is, in the mounted state of the machine-chamber front panel 31 to thetop panel 20, the temporary fixing portion can hardly be seen from outside. This can minimize the unattractive design of theoutdoor unit 100 and can also maintain workability. - In the conventional structure, an insertion portion is formed as a temporary fixing portion at an upper portion of a machine-chamber front panel. When this insertion portion is inserted inside the top panel, the insertion portion is pressed by a groove-shaped portion formed on the top panel and thus becomes deflected toward the back side, so that a reactive force against the pressing force brings the insertion portion into close contact with the inner side of the top panel to be temporarily fixed to the top panel. However, in this conventional structure, even when the machine-chamber front panel is mounted to the top panel, the insertion portion of the machine-chamber front panel is still deflected. The deflection caused by mounting the machine-chamber front panel to the top panel deforms a part of the insertion portion of the machine-chamber front panel. This leads to a problem that it is difficult to align the screw hole positions of the machine-chamber front panel and the top panel with each other, and this makes it difficult to screw the machine-chamber front panel to the top panel.
- In the present embodiment, the
insertion portion 40 is provided with the protrudingportion 40 a, the front-panel screw hole 40 b, and the recessedportion 40 c of the machine-chamber front panel 31, and thisinsertion portion 40 is positioned on the inner side of theouter box 1 relative to the other portion of the front surface of the machine-chamber front panel 31. The protrudingportion 40 a of the machine-chamber front panel 31 is engaged with the curledportion 20 a of thetop panel 20, and the curledportion 20 a of thetop panel 20 is accommodated in the recessedportion 40 c of the machine-chamber front panel 31, so that the machine-chamber front panel 31 is temporarily fixed to thetop panel 20. - As described above, when the machine-
chamber front panel 31 is temporarily fixed to thetop panel 20, the curledportion 20 a of thetop panel 20 is accommodated in the recessedportion 40 c. With this structure, at the time of the temporary fixing, a stress only acts on the protrudingportion 40 a. Thus, the machine-chamber front panel 31 and thetop panel 20 can be screwed to each other in a state where such an external force as to deflect and deform the machine-chamber front panel 31 is hardly applied. That is, the machine-chamber front panel 31 and thetop panel 20 can be screwed to each other without deforming the machine-chamber front panel 31. Consequently, this can prevent a case where it is difficult to align the position of the top-panel screw hole 20 b with the position of the front-panel screw hole 40 b, and deformation of the machine-chamber front panel 31 makes it difficult to screw the machine-chamber front panel 31 to thetop panel 20. - In the
outdoor unit 100 for an air-conditioning apparatus according to the present embodiment, the distance on thetop panel 20 between the top-panel screw hole 20 b and the curledportion 20 a is approximately equal to the distance on the machine-chamber front panel 31 between the front-panel screw hole 40 b and the recessedportion 40 c. It is thus easy to align the position of the top-panel screw hole 20 b with the position of the front-panel screw hole 40 b in the up-and-down direction, so that the machine-chamber front panel 31 and thetop panel 20 can be easily screwed to each other. - The outdoor unit 100 for an air-conditioning apparatus according to the present embodiment includes the outer box 1 having the machine chamber 10B formed therein to place the compressor 2 in the machine chamber 10B, wherein the outer box 1 includes the machine-chamber front panel 31 placed on the front side of the machine chamber 10B and removable from the outer box 1, and the top panel 20 to cover the top surface, and on the front surface of the top panel 20, the top-panel screw hole 20 b into which the screw 7 is inserted, and the curled portion 20 a having a shape curled toward the inner side at the lower end of the top panel 20 are provided, and on the front surface of the machine-chamber front panel 31, at the upper portion thereof, the insertion portion 40 is formed and recessed toward the back side, the insertion portion 40 is provided with the front-panel screw hole 40 b into which the screw 7 is inserted, and the protruding portion 40 a with a shape projecting toward the front side, and when the insertion portion 40 is inserted inside the front surface of the top panel 20, and the position of the top-panel screw hole 20 b is aligned with the position of the front-panel screw hole 40 b, the protruding portion 40 a is engaged with the curled portion 20 a.
- In the
outdoor unit 100 for an air-conditioning apparatus according to the present embodiment, when theinsertion portion 40 is inserted inside the front surface of thetop panel 20, and the position of the top-panel screw hole 20 b is aligned with the position of the front-panel screw hole 40 b, the protrudingportion 40 a is engaged with the curledportion 20 a, so that the machine-chamber front panel 31 can be temporarily fixed to thetop panel 20. The curledportion 20 a has a shape curled toward the inner side of thetop panel 20, and the protrudingportion 40 a is positioned inside the front surface of thetop panel 20. Thus, the curledportion 20 a and the protrudingportion 40 a can hardly be seen from outside. With this structure, theoutdoor unit 100 for an air-conditioning apparatus, in which theoutdoor unit 100 includes the machine-chamber front panel 31 removable from theouter box 1, can minimize the unattractive design and can also maintain workability. - In the
outdoor unit 100 for an air-conditioning apparatus according to the present embodiment, theinsertion portion 40 is provided with the recessedportion 40 c with a shape recessed toward the back side, the recessedportion 40 c is provided below the protrudingportion 40 a, and when theinsertion portion 40 is inserted inside the front surface of thetop panel 20, and the position of the top-panel screw hole 20 b is aligned with the position of the front-panel screw hole 40 b, the curledportion 20 a is accommodated in the recessedportion 40 c. - In the
outdoor unit 100 for an air-conditioning apparatus according to the present embodiment, when the machine-chamber front panel 31 is temporarily fixed to thetop panel 20, the curledportion 20 a of thetop panel 20 is accommodated in the recessedportion 40 c. With this structure, at the time of the temporary fixing, a stress only acts on the protrudingportion 40 a. Thus, the machine-chamber front panel 31 and thetop panel 20 can be screwed to each other in a state where such an external force as to deflect and deform the machine-chamber front panel 31 is not applied. That is, the machine-chamber front panel 31 and thetop panel 20 can be screwed to each other without deforming the machine-chamber front panel 31. Consequently, this can prevent a case where it is difficult to align the position of the top-panel screw hole 20 b with the position of the front-panel screw hole 40 b, and deformation of the machine-chamber front panel 31 makes it difficult to screw the machine-chamber front panel 31 to thetop panel 20. - 1
