SUMMARY OF THE INVENTION It is an object of the present invention to provide an air conditioner having improved workability in mounting a phase-advancing capacitor for a motor of a blower or a phase-advancing capacitor for a compressor.

[0006]

Means for solving the above-mentioned problems include a refrigeration cycle including a compressor, a condenser, an evaporator and the like, an upper fan case and a lower fan case, which pass through the evaporator. In an air conditioner in which a fan case for guiding air to an air outlet and a motor for driving a blower fan disposed in the fan case are provided in a main body case, a lead capacitor for the motor and a lead for a compressor are provided. A phase capacitor is sandwiched between an upper fan case and a lower fan case. As a result, the phase advance capacitor is disposed in the cold air passage, and the fan case composed of the upper fan case and the lower fan case is assembled, and at the same time, the phase advance capacitor is sandwiched and fixed.

In the above configuration, a pin is projected from an upper surface of a notch formed on a surface of the lower fan case facing the upper fan case, and the phase advance capacitor is temporarily fixed by fitting its mounting hole to the pin. Preferably, the upper surface of the upper fan case is pressed and fixed by an elastic pressing claw formed on the upper fan case. Thus, after the phase advance capacitor is temporarily fixed to the pins of the lower fan case, it is sandwiched and fixed when the fan case is assembled. Also,
Due to the elasticity of the holding claw, a dimensional error between the space formed by the cutout portion and the upper fan case and the mounting portion of the phase advance capacitor is absorbed.

A pin is projected from an upper surface of a notch formed on a surface of the lower fan case facing the upper fan case, and the phase advance capacitor is positioned by fitting its mounting hole to the pin. It is desirable to be pressed and fixed by the upper fan case via the cushion material. Thereby, the dimensional error between the space formed by the cutout portion and the upper fan case and the mounting portion of the capacitor is absorbed by the deformation of the cushion material, and the gap therebetween is also closed.
