Abstract

PURPOSE:To facilitate mounting positioning of an electric part containing box by a method wherein the right and left edge flaps of the electric part containing box is securely engaged with a trapezoidal part mounted on the bottom plate part of a body casing. CONSTITUTION:Right and left edge flaps 1a and 1b mounted on the bottom opening edge parts of an electric part containing box 1 are engaged with a pair of cut rise rails 14 on both sides formed at a trapezoidal part 6a of the bottom plate part of a body casing 6. By inserting the electric part containing box 1 along the cut rise rails 14, a front edge flap 1f is brought into contact with the front wall of the trapezoidal part 6a to position a whole. With this state, by fastening a screw 13 against a screw hole 15 formed in the front wall of a trapezoidal part 6a of a body casing 6 through the front edge flap 1f, the electric part containing box 1 is secured in this position. In removal of the electric part containing box, the screw 13 may be unscrewed by reversing the aboves.

In the case of the invention as claimed in claim 1, a trapezoidal portion that protrudes inward is formed in the bottom plate portion of the main body casing, and the left and right edges 7 lamps and the front lamps are provided on the top wall of this trapezoidal portion at the opening edge of the electrical component storage box. An electrical parts storage box having edge flaps is provided, and the left and right edge flaps are engaged and fixed, and the front edge flap is prevented from collapsing against the front wall of the trapezoidal part.

In addition, in the case of the invention of claim 2, there is provided an outdoor unit in which a substantially rectangular parallelepiped-shaped electrical component is installed in a blower chamber, and the electrical component is placed at opposite corners of the substantially rectangular parallelepiped so as to follow the flow of wind in the air passage. The 9 electrical components are arranged linearly, the ridges are rounded, and the 9 electrical components are covered by an electrical component storage box with an open bottom.

[Effect]

In the case of the invention of claim 1, the left and right edge flaps of the electrical component storage box are engaged and fixed to the trapezoidal portion provided on the bottom plate of the main body casing, thereby positioning the electrical component storage box. The electronics storage box is secured in position by a leading edge flap that is screwed in abutment to the front wall of the unit.

In addition, in the case of the invention of claim 2, the electrical components are arranged linearly with opposing corners of a substantially rectangular parallelepiped so as to follow the flow of the wind,
By making the ridgeline round and covering the electrical components with an open bottom electrical component storage box, the air flow is smooth and turbulent, and the noise is also quiet.
