BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 to 3, the same members as those in FIGS. 4 to 6 are denoted by the same reference numerals.

In FIG. 1, reference numeral 20 denotes an opening provided in a side wall facing the air passage of the air conditioner main body 1, and this opening 20 is normally closed by screwing a blind plate 21. ing. To attach the unit-type evaporative humidifier 22 to the air conditioner main body 1, remove the blind plate 21 from the air-conditioner main body 1, and connect the unit-type evaporative humidifier 22 to the inside of the air conditioner main body 1 through the opening 20. It is performed by arranging it at a position facing the air passage.

Unit type evaporative humidifier 22 of an air conditioner
As shown in FIG. 2, the evaporative humidifier drain plate 23 and the fixing plate 24 are integrally connected to each other to form the evaporative humidifier drain plate 23.
The vaporizing humidifier 25 is arranged inside the, and the control part box 26 of the vaporizing humidifier, the electromagnetic valve 27 for water supply, and the pressure reducing valve 28 are fixed on the surface of the fixing plate 24 opposite to the surface of the drain plate 23 of the vaporizing humidifier. It is constituted by doing. Vaporizing humidifier drain plate 2
3 is fixed to the side wall so as to cover the opening 20 of the side wall facing the air passage of the air conditioner body 1. The vaporizing humidifier 25 and the water supply pipe connection port 29 of the unit type vaporizing humidifier 22 are connected to a water supply solenoid valve 27.
And a water supply tube 30 via a pressure reducing valve 28, but in some cases, the members may be directly connected to each other. The connection between the evaporative humidifier 25 and the water supply pipe connection port 29 is made at the manufacturing stage, and as a whole, the unit-type evaporative humidifier 22 is formed. Therefore, when installing the unit-type evaporative humidifier 22 to the air conditioner main body 1, on-site water supply piping work is only connection work to the water supply pipe connection port 29.

On the other hand, the evaporative humidifier drain plate 23 is provided with an internal drain port 31 and an external drain port 32. The internal drain port 31 extends downward from the lower surface of the drain plate 23 and is disposed so as to open right above the drain plate 9 of the heat exchanger 7 disposed inside the air conditioner main body 1. The external drain port 32 extends laterally from the side surface of the drain plate 23 and extends outside the fixed plate 24 through a hole (not shown) provided in the fixed plate 24. Therefore, the internal drain port 31 provided in the evaporative humidifier drain plate 23 is used to transfer the drain water collected in the evaporative humidifier drain plate 23 to the drain plate 9 of the heat exchanger 7 unless closed by a closing member (not shown). Send in. A drain pipe (not shown) is connected to the external drain port 32. In order to incorporate the unit-type evaporative humidifier 22 into the air conditioner main body 1, first, the unit type evaporative humidifier 22 is provided in the opening 20 on the side wall of the air conditioner main body 1. The unit-type evaporative humidifier 22 is removed, and the unit-type evaporative humidifier 22 is inserted into a predetermined position inside the air-conditioner main body 1 through an opening 20 provided in a side wall of the air-conditioner main body 1. 22 is fixed by ordinary fixing means, and the fixing plate 24 is fixed to the side wall so as to cover the opening 20 of the side wall facing the air passage of the air conditioner main body 1. When the drain water of the vaporizer humidifier 25 provided in the unit-type vaporizer humidifier 22 is shared with the drain water of the air conditioner, the internal drain port 31 provided in the vaporizer humidifier drain plate 23 is connected to the air conditioner. The external drain port 32 provided in the evaporative humidifier drain plate 23 is closed by a closing tool (not shown). When drainage of the evaporative humidifier 25 provided in the unit type evaporative humidifier 22 is performed separately from drainage of the air conditioner, a drain pipe (not shown) is connected to the external drain port 32, and the external drain is connected. The opening 32 is opened, and the internal drain opening 31 is closed by a closing tool (not shown).

[0016]

As described above, according to the present invention, the evaporative humidifier drain plate and the fixing plate are integrally connected, and the evaporative humidifier is disposed inside the evaporative humidifier drain plate and fixed. By attaching the control part box of the vaporizing humidifier and the solenoid valve for water supply to the plate, the work of mounting to the air conditioner is simplified.

Further, since the control components are concentrated on one surface of the fixing plate, maintenance work of the control components is simplified.

In addition, the provision of an internal drain port extending downward from the lower surface and an external drain port extending through the fixing plate from the side surface of the evaporative humidifier drain plate allows drain piping to be selected. Responsiveness increases.
