Then, when the turbo fan 26 is rotationally driven, indoor air is sucked from the suction port 16 and is sent to the heat exchanger 38. After heat exchange with the heat exchanger 38, the air-conditioned air is blown out. It is designed to be blown into the room R from 18. A refrigerant pipe 34 is connected to the heat exchanger 38, and the refrigerant is supplied from an outdoor unit (not shown) through the refrigerant pipe 34. 4 bolts 4 from the building 40
2 is set vertically downward, and these bolts 42 are connected to a hanging metal fitting 44 fixed to the main body casing 22.

As shown in FIGS. 2 and 3, the air conditioner 1
In the suction port 16 of the makeup panel 14 of 0, the electrostatic precipitator 20
Is provided. The electrostatic precipitator 20 has a case 50, and the case 50 has a main body 50b and a lid 50a that can be opened and closed in the R direction. As shown in FIG. 8, the main body 50b is openably and closably coupled to the panel frame of the decorative panel 14 near the suction port 16 by using a hinge 66. The lid 50a is openably and closably coupled by a hinge 66 as shown in FIG. 7 corresponding to the suction port 16 of the air conditioner 10. As shown in FIG. 4, the electrostatic precipitator 20 is formed by accommodating a filter element 62 having a charging property in a case 50, and the electrostatic precipitator 20 has a fine dust 100.
When particles enter, the dust is collected by the chargeability of the filter element 62.

According to this embodiment, since the filter has a very coarse mesh, even if the electrostatic precipitator 20 is present in the suction port 16, it has almost no effect on the amount of air passing through the suction port 16. Never give.

As shown in FIG. 5, a power box 121 is provided at the end of the electrostatic precipitator 20, and a limit switch 120 is provided in the power box 121.
According to this, as shown in FIG. 5, when the suction grill 52 is opened to clean the filter element 62 or the inside of the air conditioner 10 is maintained, the limit switch 120 is turned off, so that the power supply to the electrostatic precipitator 20 is applied. Can be reliably turned off.
