Abstract: An electric equipment assembly is sized and configured to be disposed in a machine chamber of an outdoor unit. Reduction in size of the electric equipment assembly is achieved and simultaneously visibility and serviceability of a highly frequently accessed element are ensured, while employing a structure in which a control circuit board is covered by a protection cover. The electric equipment assembly includes a frame having a substrate attachment plate to which a control circuit board mounted with various electric components is attached and a substrate protection plate which covers the control circuit board. The outer surface of the substrate protection plate has a first auxiliary attachment portion formed thereon, to which a first auxiliary circuit board different from the control circuit board and mounted with a highly frequently accessed control element is attached.

Abstract: An electrical equipment assembly includes a control board and a frame. The control board is disposed lengthwise inside a casing, and various types of electrical parts are mounted on the control board. The frame is a member that holds the control board. Slits that drain water that is present between the frame and the control board are formed in a lower portion of the frame. Water guide paths that guide the water to the slits are formed in a surface of the frame that faces a board surface of the control board.

Abstract: In a plate shaped shut-off valve support member configured to support a shut-off valve to which a refrigerant pipe on an indoor unit side is connected, and configured to be extended across a first fixing portion and a second fixing portion of an outdoor unit, the operability of a service port of the shut-off valve is ensured and the strength of the shut-off valve support member is improved. A shut-off valve support member (30) comprises an attachment portion (35), an interference prevention portion (36), and a stepped portion (37). A shut-off valve (61, 62) is attached to the attachment portion (35) with a service port (61a, 62a) of the shut-off valve (61, 62) protruding in a direction perpendicular to a longitudinal direction of the shut-off valve support member.

Abstract: An outdoor unit of an air conditioner which is partitioned into a fan chamber disposed with a fan and a machine chamber other than the fan chamber and in which a heat-emitting part is disposed includes a casing and a impermeable plate. The casing is disposed inside the fan chamber, is disposed with openings, and houses inside the heat-emitting part. The impermeable plate employs a structure where the impermeable plate is disposed in the casing between a position where the openings are disposed and a position where the heat-emitting part is housed, and through which it is more difficult for water to pass than air. Thus, the outdoor unit of the air conditioner is configured to improve the effect of cooling a heat-emitting part while preventing water from coming into contact with the heat-emitting part.
