The eliminator 25 made of the filter material is arranged, and the water supplied by the water supply pipe 26 is sprayed from the heat exchanger side to the eliminator 25 by the spray nozzle 27.

The fine water droplets sprayed from the spray nozzle 27 are eliminators.
It reaches 25, and while flowing down, it vaporizes on the surface and mixes into the air flow to humidify the air.

Excess water that has not evaporated on the surface of the eliminator flows down as it is, drops from the lower end of the eliminator into the drain pan 28, and is discharged from the drain pipe 29 to the outside of the air conditioner.

In addition, by closing the valve 30 provided in the middle of the water supply pipe,
It is also possible to stop humidifying the air and continue the operation of the air conditioner.

The conventional air conditioner with a humidifier is as described above, and tap water is usually used for the humidifier for an air conditioner, but the tap water contains trace amounts of impurities such as silica and calcium. Since these impurities adhere to the eliminator and remain, if the air blower is operated during drying of the eliminator, the impurities deposited on the surface of the eliminator will scatter and be discharged from the air conditioner while being mixed in the air flow, so-called white. The phenomenon that the powder flies occurs.

[Object of the Invention] The present invention can provide a humidifying device for an air conditioner and an air conditioner with a humidifying device, in which the impurities in the tap water deposited are not discharged to the outside of the air conditioner. I chose

Also, when operating the humidifier, the blower of the humidifier is set to operate after a certain period of time has elapsed since the solenoid valve of the water supply pipe was opened, so the humidification element must be sufficiently operated before the blower for humidification operates. Get wet.

When the humidifying element is wet, the impurities deposited on the element are dissolved, and the impurities do not scatter even if the blower operates.

[Embodiment of the Invention] Next, an embodiment of the invention will be described in detail with reference to FIGS. 1 to 5.

Reference numeral 1 is a humidifying device main body according to the present invention, and a humidifying blower 4 is provided at, for example, the air outlet 3 of a casing 5 having an air inlet 2 and an air outlet 3.

And, for example, tap water for humidification can be supplied to the inside of the humidifier 1 by a water supply pipe 7 provided with an electromagnetic valve 6 in the middle thereof, and the water supply pipe 7 is ventilated above the inside of the humidifier 1, for example. A water supply pipe upper part 7a extending laterally is formed so as to be orthogonal to the path, and its terminal end is a closed end.

From this water supply pipe upper portion 7a, a large number of water supply branch pipes 9 having a large number of water discharge holes 8 in the periphery are provided horizontally, for example, on the air outlet 2 side. For example, a cloth-like material such as a nonwoven fabric having excellent water resistance is used. The humidifying element 10 formed in the above is wound around the circumferential surface of each water supply branch pipe 9 so that the peripheral surface of the water supply branch pipe 9 is a humidifying element.
It's wrapped in 10.

The humidifying element 10 which encloses the water supply branch pipe 9 has both inner side surfaces stuck to each other and hangs down vertically in a plate shape, and the bottom side 10c is slanted so that the side side 10a is longer than the side side 10b, for example. It has been cut into.

A drain pan 12 to which a drain pipe 11 is connected is provided below the humidifying element 10.

The control circuit of the humidifying device is, for example, as shown in FIG. 5, and is connected so that, for example, when the starting switch S of the humidifying device is closed, the electromagnetic relay MC and the timed relay TR are energized.

Further, the a-contact r of the electromagnetic relay serving as the opening / closing switch of the solenoid valve 6 is closed at the same time as the energization of the electromagnetic relay MC, and the time-relay TR closes the a-contact t of the time-relay after a certain time has passed after the energization. If the contact a of the timed relay TR is closed, the motor B of the humidifying blower 4 is closed.
Are connected to operate.

Reference numeral 13 is an air conditioner with a humidifying device according to the present invention,
For example, a humidifier 15a and a cooler 15b are attached to the downstream of the air inlet 14 with a support 16a, an air conditioner main blower 18 is provided at the air outlet 17, and the cooler 15b and the air conditioner main are provided. The humidifying device 1 is placed at a suitable position in the space between the blower 18 and the support 16
It is installed in the main body of the air conditioner 13 with a humidifier at b.

In the humidifying device and the air conditioner with a humidifying device according to the present invention configured as described above, when performing the air conditioning operation without operating the humidifying device 1, the heater 15a enters through the inflow port 14
The air that has undergone heat exchange with the cooler 15b or the cooler 15b is discharged from the main air blower 18 for the air conditioner through the air passage A directly leading to the main air blower 18 for the air conditioner.

Next, when the start switch S of the humidifying device is closed, the contact a of the electromagnetic relay MC is closed and the electromagnetic valve 6 is opened, tap water is supplied from the water supply pipe 7 into the humidifying device 1, and the water passes through the water supply branch pipe 9. The humidifying element 10 is heated by the hot water leaking from the water discharge hole 8.
To wet.

In addition, the time relay in which the contact a is closed after the elapse of a certain time required for the humidifying element 10 to be sufficiently moistened.
The TR starts counting at the same time as closing the start-up switch S of the humidifying device, and after the elapse of the predetermined time, closes the a contact t to operate the motor B of the humidifying blower 4.

After the operation of the humidifier blower 4, the air flow is divided into both the ventilation passages A and B, and the air flow passing through the ventilation passage B is mixed with the water vaporized on the surface of the humidification element 10 while passing through the humidification device 1. As a result, moist air is discharged from the humidifying device, and the air that has passed through the ventilation passage A is mixed to form an appropriate humid air.

Excess water that did not evaporate during flowing down the humidifying element 10 flows to the lower part of the humidifying element, and concentrates down to the bottom of the bottom 10c of the humidifying element that is cut diagonally and drops into the drain pan 12, It is discharged from the drainage pipe 11 to the outside.

[Effect] Since the humidifying device for an air conditioner and the air conditioner with a humidifying device according to the present invention are installed in the air conditioner by housing the humidifying device in a casing having an inflow port and an outflow port, the humidifier is installed in the air conditioner. An air passage leading directly to the outlet and an air passage passing through the heat exchanger and passing through the humidifying device to reach the outlet can be provided.

As a result, the air flow when the humidifier does not operate will be discharged to the outside of the air conditioner through the former ventilation passage, and the impurities in the tap water deposited on the surface of the humidification element will not mix with the air flow. Therefore, the air mixed with white powder is not discharged.

Also, when operating the humidifier, first of all, moisten the humidifying element with water supply for a required time by a timer, dissolve impurities in the tap water deposited on the element surface into tap water again, and then operate the blower. Therefore, impurities are not scattered even if the element is not cleaned, and white powder is not discharged at this time.

Note that the output of the main blower for the air conditioner is particularly large, and the inlet and outlet of the humidifier are larger than the ventilation passage of the air conditioner, so even when the humidifier is stopped. If the airflow flows into the humidifier, if the humidifier is installed at an angle so that the ventilation passage in the humidifier is not parallel to the ventilation passage of the air conditioner, the air will flow into the humidifier. It is possible to prevent
