Outdoor unit of air conditioner

Abstract

The invention provides an outdoor unit of an air conditioner with high reliability, which can quickly discharge the drained water outside the outdoor unit without accumulating around the heat exchanger, and can prevent the drained water from freezing and causing the heat exchanger to deform. The bottom plate (5) constituting the bottom of the frame body (1) has: a bottom plate portion (5a); a flange (10) formed by turning upwards from the periphery of the bottom plate portion; a drainage hole (7) formed through the bottom plate portion, The drainage hole drains the water in the frame to the outside of the frame; the multiple mounting platforms (9, 13, 15) provided on the bottom plate protrude toward the inside of the frame at a predetermined distance from the flange, The lower end of the heat exchanger (3) is supported by its top surface (9a, 13a, 15a); and the drain groove (8) is connected to the mounting table and formed by a downward slope toward the drain hole. The bottom plate portion between the mounting table and the flange is composed of an inclined portion (11) inclined in the longitudinal direction of the flange and facing the drainage groove.

Description

technical field [0001] The present invention relates to an outdoor unit of an air conditioner, and more particularly to a drainage structure for discharging water. Background technique [0002] The outdoor unit of the air conditioner is formed of a substantially rectangular parallelepiped housing, and a compressor, an outdoor heat exchanger (hereinafter referred to as a heat exchanger), a blower, and the like are provided inside the housing. A partition wall is formed between the portion where the compressor is installed and the portion where the heat exchanger and the blower are installed. The heat exchanger is arranged in a substantially L-shape along the side surfaces of the housing. In addition, a drain hole penetrating through the base plate is formed on the base plate constituting the bottom of the housing, and water accumulated inside the housing is discharged to the outside through the drain hole. Therefore, the drainage hole is arranged at the lowest position of t...

AI Technical Summary

Problems solved by technology

It also causes the problem that the large amount of water remains on the bottom plate of the outdoor unit and freezes without being discharged outside the outdoor unit.

If the ice formed as described above gradually grows around the heat exchanger or the blower, it will hinder the rotation of the blower, or the heat transfer tube of the heat exchanger will be deformed due to pressure from the surroundings due to the ice.
