On the lower surface of the diffusing cloth portion 24, the upper ends of a plurality of strip-shaped vaporizing cloth portions 25, 25, ... Are closely contacted from below in the vertical direction, and the lower end portions of the vaporizing cloth portions 25 in the drawing are stored in a water tank. A plurality of slits 22 a on the lower surface of 22 hang vertically downward in a watertight manner.

Below each of the water storage tanks 22, a tray 26 having a shape of a bottomed rectangular tube is arranged substantially parallel to each other, and each vaporizing cloth portion 2 is placed in the tray 26.
5, the water drops drip from the vaporizing cloth portions 26 are stored and stored, and the vaporizing cloth portions 2 are stored in the stored water d.
5 is soaked at the lower end that it is sucked up by the capillary phenomenon to the upper part of each vaporized cloth portion 25 to be constantly moistened.

A drain pipe 28 provided with a drain valve 27 composed of an electromagnetic valve is connected to one end of the tray 26 so that the stored water d in the tray 26 is discharged to the outside or the drain pan 5 shown in FIG. 4 or the like. There is.

The drain valve 27 is connected to a controller 29 composed of a microcomputer or the like, so that the controller 29 constantly immerses the lower ends of the vaporizing cloth portions 25 in the water d stored in the tray 26 to keep them wet. In addition, the opening / closing of the drain valve 27 is controlled so that the water level of the stored water d is always maintained at a predetermined water level.

Further, the lower end portion of each vaporizing cloth portion 25 is provided with a tray 26.
If soaked in the stored water d for a long time, the concentration of impurities in the stored water d increases and clogging occurs in the vaporizing cloth portion 25. In order to prevent this, almost all the stored water d in the tray 26 is to be prevented. It is designed to drain appropriately.

FIG. 2 is a flow chart of a processing program of the controller 29, and P1 to P10 in the figure show respective steps of the flow chart.

The controller 29 first confirms at P1 that the operation mode of the air conditioner is the heating operation, then initializes at P2, and then at P3, feeds the water supply pipe to the water tank 22 of the vaporization humidifier 21. Water supply starts from 23.

At P4, it is judged whether or not the water level in the tray 26 has reached a predetermined water level. If NO, the process returns to P3 again and YE
If S, proceed to P5 and stop water supply.

Thereafter, at P6, it is judged whether or not the lower end of the vaporizing cloth portion 25 is immersed in the water d stored in the tray 26, and Y
In the case of ES, keep the water supply stopped, and in the case of NO, P7
Then, the number n of the NO is counted.

In P8, it is judged whether or not the number of times n has reached a predetermined number, and in the case of NO, the process returns to P3 again to start water supply,
The water level of the stored water d in the tray 26 is maintained at a predetermined water level.

If YES in P8, the drain valve 27 is fully opened in P9 to drain the water stored in the tray 26, and the water supply pipe 2
Water is supplied from 3 to wash each vaporized cloth portion 25, the water after the washing is drained, the drainage is stopped at P10, the process returns to P2 again, and so on.

Next, the operation of this embodiment will be described.

When the water is supplied from the water supply pipe 23 into the water tank 22, the water is supplied to the plurality of small holes 25, 2 of the water supply pipe 23.

Further, this water supply soaks into the upper ends of a plurality of vaporizing cloth portions 25 and flows downward, and a part thereof, for example, 7% is vaporized and humidified in the air, and the rest, for example, about 93%. Is dripped into the saucer 26 and water is stored therein.

When the water level of the tray 26 reaches a predetermined level, the controller 29 stops the water supply.

However, the lower end of each vaporizing cloth portion 25 is the receiving tray 2
Since the water is dipped in the stored water d of 6, the stored water level d is sucked upward by the capillary phenomenon and wets and vaporizes each vaporizing cloth portion 25, so that the humidification can be performed even when the water supply is stopped.

However, by repeating this, the impurity concentration of the stored water d in the tray 26 becomes high and clogging occurs, so the controller 29 appropriately opens the drain valve 27 fully and the tray 2 is opened.
After draining almost all of the stored water d of 6, the water supply pipe 23
Water is restarted, and cleaning water is flown down through the vaporizing cloth portions 25 to prevent clogging, the water after cleaning is drained, and this is repeated thereafter.

Therefore, according to the present embodiment, since the lower end of each vaporizing cloth portion 25 is constantly dipped in the water d in the tray 26 to be wetted, it can be humidified even when the water supply is stopped. Therefore, it is possible to save the water supply and reduce the operating cost.

FIG. 3 shows another embodiment of the present invention,
This is configured so that the pan 26 can be rotated around the shaft 30. By rotating the pan 26 around the shaft 30, the stored water d in the pan 26 is drained to, for example, the drain pan 5 shown in FIG. It was done.
