Problems solved by technology

In addition, when water enters between the control substrate and the frame, the water may accumulate between the control substrate and the frame (especially the lower part of the frame) due to surface tension, which may cause a pattern caused by water contacting the control substrate. Control board short circuit and other bad conditions
In this regard, there is also a technique to prevent water from entering between the control board and the frame by providing a seal or the like on the mounting portion between the radiator and the frame, but in this case, the cost of the seal and the installation time of the seal are increased , can also cause water ingress due to misalignment of the seal

Abstract

An electrical equipment assembly placed in a casing of an outdoor unit, in which a failure such as a short circuit in a control board caused by the water in contact with a pattern on the board is less likely to occur even if water enters between the control board and a frame. The electrical equipment assembly (7) has the control board (91) and the frame (71). The control board (91) is vertically placed in the casing (2) and has various electrical components mounted on it. The frame (71) is the member for holding the control board (91). In the lower part of the frame (71) are formed slits (75a-75c) for discharging water between the frame and the control board (91), and a water leading path for leading water to the slits (75a-75c) is formed in the surface opposite a board surface of the control board (91).

Description

technical field [0001] The present invention relates to an electrical installation assembly and an outdoor unit of an air conditioner with the assembly, in particular to an electrical installation assembly arranged in the casing of the outdoor unit and an outdoor unit of the air conditioner with the assembly. Background technique [0002] Conventionally, there is an outdoor unit of an air conditioner in which the interior of a substantially rectangular parallelepiped box-shaped casing is divided into a blower chamber and a machine chamber by a partition plate extending in a vertical direction. An outdoor heat exchanger and an outdoor fan are mainly arranged in the blower room. In the mechanical room, there are mainly compressors, refrigerant circuit components including valves and refrigerant piping, and electrical components. Among such electrical component assemblies, there is an assembly including a longitudinally arranged control substrate and a frame holding the contro...
