## Abstract

An electric equipment assembly has a frame with various electric components attached to the frame. The electric components include a control circuit board mounted with operating control elements and an inverter control element. Preferably the electric equipment assembly is disposed in outdoor units of an air conditioner. Each outdoor unit includes a structure in which the inside of a casing has a generally rectangular parallelepiped box shape divided into a fan chamber and a machine chamber by a partition plate extending vertically. The frame is provided such that a substrate surface of the control circuit board is positioned along a partition plate and is also inclined to a front side of the unit casing, with the frame provided in a unit casing so that an increase in airflow resistance in a fan chamber is prevented and the on-site workability is ensured at the same time.

## Claims

### Claim 1

An electric equipment assembly sized and configured to be disposed in a machine chamber of an outdoor unit of an air conditioner having a structure in which an inside of a casing having a generally rectangular parallelepiped box shape is divided into a fan chamber and the machine chamber by a partition plate extending vertically, the electric equipment assembly comprising:
a frame; and
a plurality of electric components attached to the frame, the electric components including a control circuit board with operating control elements and an inverter control element,
the frame being disposed such that a substrate surface of the control circuit board is positioned along the partition plate and is also inclined relative to a front side of the casing when the frame is disposed in the machine chamber of in the casing.

### Claim 2 (depends on 1)

The electric equipment assembly according to claim 1, wherein
the frame has a generally rectangular shape as viewed along a plan view of the casing when the frame is disposed in the machine chamber of the casing, and
a corner of the frame on a partition plate side is in contact with the partition plate so as to be positioned along a bent surface of the partition plate when the frame is disposed in the machine chamber of the casing.

### Claim 3 (depends on 1)

The electric equipment assembly according to claim 1, wherein
the operating control elements include a frequently accessed control element disposed closer to the front side of the casing when the frame is disposed in the machine chamber of the casing.

### Claim 4 (depends on 3)

The electric equipment assembly according to claim 3, wherein
the frame is inclined relative to the front side of the casing when the frame is disposed in the machine chamber of the casing such that an entirety of the frequently accessed control element is visible without being hidden by a lateral side of the casing even when the frame is viewed in a direction perpendicular to the substrate surface when the frame is disposed in the machine chamber of the casing.

### Claim 5 (depends on 3)

The electric equipment assembly according to claim 3, wherein
the frame includes a substrate attachment plate disposed along the partition plate and a substrate protection plate configured to cover the substrate attachment plate from a side opposite the partition plate when the frame is disposed in the machine chamber of the casing, and
the substrate protection plate has an auxiliary circuit board attached to an outer surface thereof, the auxiliary circuit board being different from the control circuit board and mounted with the frequently accessed control element.

### Claim 6

An outdoor unit of an air conditioner comprising:
a casing having a generally rectangular parallelepiped box shape;
a partition plate extending vertically so as to divide an inside of the casing into a fan chamber and a machine chamber; and
an electric equipment assembly, disposed in the machine chamber of the casing, the electric equipment assembly including
a frame, and
a plurality of electric components attached to the frame, the electric components including a control circuit board with operating control elements and an inverter control element,
the frame being disposed such that a substrate surface of the control circuit board is positioned along the partition plate and is also inclined relative to a front side of the casing.

### Claim 7 (depends on 6)
