Outdoor unit for air-conditioning apparatus

Abstract

An outdoor unit for an air-conditioning apparatus includes an outer box having a machine chamber formed therein in which a compressor is placed. The outer box includes a machine-chamber front panel placed on a front side of the machine chamber and removable from the outer box, and a top panel to cover a top surface. In a front surface of the top panel, a top-panel screw hole into which a screw is inserted, and a curled portion having a shape curled toward an inner side at a lower end of the top panel are provided. On a front surface of the machine-chamber front panel, at an upper portion thereof, an insertion portion is formed and recessed backward. The insertion portion is provided with a front-panel screw hole into which a screw is inserted, and a protruding portion with a shape projecting toward a front side. When the insertion portion is inserted inside a front surface of the top panel, and a position of the top-panel screw hole is aligned with a position of the front-panel screw hole, the protruding portion is engaged with the curled portion.

1 . An outdoor unit for an air-conditioning apparatus, the outdoor unit comprising an outer box having a machine chamber formed therein in which a compressor is placed, wherein
 the outer box includes   a machine-chamber front panel placed on a front side of the machine chamber and removable from the outer box, and   a top panel to cover a top surface,   in a front surface of the top panel, a top-panel screw hole into which a screw is inserted, and a curled portion having a shape curled toward an inner side at a lower end of the top panel are provided,   on a front surface of the machine-chamber front panel, at an upper portion thereof, an insertion portion is formed and recessed backward,   the insertion portion is provided with a front-panel screw hole into which a screw is inserted, and a protruding portion with a shape projecting toward a front side of opening of the top-panel screw hole, and   when the insertion portion is inserted inside a front surface of the top panel, and a position of the top-panel screw hole is aligned with a position of the front-panel screw hole, the protruding portion is engaged with the curled portion.
