Outdoor unit of air conditioner

An outdoor unit of an air conditioner, comprising an electrical component box comprising:

• a partition plate sectioning the electrical component box from an inner part of the outdoor unit;
• a box base plate comprising a flange bent downward in a periphery thereof and sectioning the electrical component box from the inner part of the outdoor unit;
• a front plate fixed to the flange of the box base plate and sectioning the electrical component box from the inner part of the outdoor unit;
• an L-shaped arm made of an elongated steel plate, having
• an upper flange formed at an upper edge and a lower flange formed at a lower edge under the upper flange, both being bent substantially perpendicularly to a center portion thereof,
• an insertion hole at the lower flange,
• a screw hole above the insertion hole,
• a rounded corner bent from the elongated steel plate as viewed from a top,
• a straight part extending from the rounded corner, and
• an abutment surface at an end of the straight part;
• and
• a support post connecting the straight part of the arm and the flange of the box base plate,
• wherein the front plate covers a front side of the electrical component box and has one end fixed to one end of the partition plate,
• the box base plate is fixed to the partition plate at a bottom part of the partition plate and fixed to the front plate on a side of the box base plate,
• the arm has the abutment surface that abuts at a right angle against a rear surface of the front plate and one end coupled to another end of the partition plate,
• the support post is fixed perpendicularly to the arm and the box base plate and connects the arm and the box base plate in a vertical direction of the outdoor unit,
• the support post comprises a first part, a second part, and a third part,
• the second part and the third part extend perpendicularly from the first part,
• the first part includes a receiving part at an upper part thereof bent toward a back side of the electric component box and supporting the lower flange of the arm at a middle in a longitudinal direction of the arm,
• a lower end of the first part and a lower end of the second part contact with a top surface of the box base plate,
• the third part is fixed to the flange of the box base plate,
• the third part has a screw hole at a bottom end thereof,
• the box base plate has a screw hole on the flange,
• the third part and the flange are fixed with a screw screwed into the screw holes of the third part and the flange,
• an upper end of the third part of the support post includes an insertion piece engaging the insertion hole and having a screw hole, and
• the insertion piece is engaged with the insertion hole and is connected by a screw entering into the screw hole of the L-shaped arm and the screw hole of the insertion piece.
