Are locked at the upper and lower ends without coming off the outdoor unit 1. By fastening the screw 36 to the overlapping hole 35b and the screw hole 18 from above, the spray mounting member 13 can be easily fixed to the outdoor unit 1. Further, at this time, since all the work of attaching the spray attachment member 13 to the outdoor unit 1 can be performed from above, the gap between the side surface of the outdoor unit 1 on which the water sprinkler 10 is attached and an obstacle such as the wall 2 is provided. Even if it is small, even if the worker does not enter the gap side as in the prior art, the installation work can be easily performed by looking into the gap-free side without any obstacle.

Next, the other end of the water pipe 11a is connected to the solenoid valve 24 of the control unit main body 11 by screwing or the like, and the cover 2 is
0 is attached to the base 14 with the screw 20a.
0 is completed. In addition, in this Embodiment 1, before fixing the spray mounting member 13 to the outdoor unit 1,
Sprinkler spray 12 was attached to spray mounting member 13,
If there is an obstacle such as the wall 2, the work becomes slightly difficult, but it may be attached later.

Next, the driving operation will be described with reference to the flowchart of FIG. First, when the air conditioner is operated, the outdoor unit 1 is operated, power is supplied to the water sprinkler 10, and the operation is started in step 100. Next, in step 101, it is checked whether the solenoid valve 24 works reliably, and whether the test run switch 28, which is a switch for checking whether the water spray 12 is clogged, or the like, has been pressed. If it has been pressed, at step 102, the solenoid valve 2
4 is opened and closed to repeat watering for 10 seconds and watering stop for 10 seconds three times. At step 103, the information on the press of the test run switch 28 is cleared and the process returns to step 101. If the test run switch 28 has not been pressed in step 101, the process proceeds to step 104, and it is determined whether the cleaning switch 29 of the cleaning means, which is a switch for cleaning the heat exchanger 3, has been pressed. If the washing switch 29 is pressed, watering is started in step 105, and in step 106, it is detected whether the washing switch 29 is pressed again within 10 minutes after the watering is started, and if it is pressed again, Step 1
At 08, watering is stopped.

If the washing switch 29 has not been pressed again in step 106, it is determined in step 107 whether or not the watering time has elapsed 10 minutes. After watering has been performed for 10 minutes, the process proceeds to step 108 and stops watering. That is, as long as the cleaning switch 29 is not pressed again for 10 minutes, continuous watering for cleaning is performed.
Next, in step 109, the information on the pressed cleaning switch 29 is cleared, and the process returns to step 101. Step 104
If the cleaning switch 29 is not pressed in step 1,
Proceeding to 10, the operation mode of the setting switch 27 is determined, and if the operation mode is set to the overload mode, step 111 is executed.
It is determined whether the outside air temperature detected by the temperature sensor 44 is 40 ° C. or higher at which overload is detected. If the temperature is 40 ° C. or higher, the process proceeds to step 113 for watering, and if lower than 40 ° C., the process returns to step 101. .

If the energy saving mode has been set in step 110, the process proceeds to step 112, where the outside air temperature is set to 32 ° C.
If it is above, step 1 for watering for energy saving
If the temperature is lower than 32 ° C., there is no problem. If it is determined in steps 111 and 112 that the outside air temperature is equal to or higher than the set temperature and that watering is necessary, it is determined in step 113 whether five minutes have elapsed since the last watering. Return to 101. This is because the heat exchange efficiency of the heat exchanger 3 is better and the water is cut off when the next watering is performed after the previous watering has evaporated to some extent. If the outside air temperature is high, watering is performed every five minutes. If five minutes have elapsed since the last watering in step 113, the process proceeds to step 114, and the setting of the watering time of the setting switch 27 is determined. If the watering time is set to 30 seconds, the solenoid valve 24 is opened for 30 seconds in
Water is sprayed for second and the process returns to step 101.

In step 114, the setting switch 27
If the watering time is set to 15 seconds, the electromagnetic valve 24 is opened for 15 seconds in step 116 to spray water for 15 seconds, and the process returns to step 101 to continue the operation. It should be noted that the watering durations of 30 seconds and 15 seconds in steps 115 and 116 are used for adjusting the amount of water discharge due to the difference in the water pressure conditions and for watering the outdoor unit 1 of a type having a different size of the heat exchanger 3. It is used when setting the watering amount of the water properly.

In the first embodiment, since the washing means for continuously sprinkling water for 10 minutes for washing is provided, the sprinkled water can be used for cleaning the heat exchanger 3, and the heat exchange performance can be conveniently improved. Contribute to energy saving. In the first embodiment, the watering time for cleaning is set to 10 minutes. However, the watering time is not limited to 10 minutes, and the cleaning switch 29 is frequently turned on for a time longer than the normal watering time of 30 seconds or 15 seconds. Do not press
A similar effect can be obtained even if watering is continued for a time generally available for cleaning, for example, about 3 to 20 minutes. Further, as in the first embodiment, when the washing switch 29 is pressed again during washing watering, the watering is stopped and the operation is returned to the normal operation, so that the watering can be stopped as soon as the washing is over, and No water is wasted when the cleaning switch 29 is pressed.

Embodiment 2 Next, a second embodiment will be described. 15 to 20 show a second embodiment. FIG. 15 is a perspective view of a mounting angle of the second embodiment, FIG. 16 is a front view of a main part of a portion K in FIG. 15, and FIG. -M line sectional view, FIG. 18 is a perspective view equivalent to FIG. 1 with the spray attachment member attached, and FIG. 19 corresponds to FIG. 18 with the spray attachment member attached to an outdoor unit taller than FIG. FIG. 20 is a perspective view of a main part of the mounting angle of FIG. 19 corresponding to FIG.

In the above-described embodiment, the vertical angles 37 and 38 are freely movable up and down, and the vertical angles 37 and 38 are not separated as long as the vertical angles 37 and 38 are not deviated vertically. However, only the vertical angles 37 and 38 are attached. If the screw 42 is tightened, it may be fixed, and it is necessary to support by hand or the like so that the upper and lower angles 37, 38 do not separate until the screw 42 is tightened.
The same effect is obtained in that the length of the mounting angle 30 can be adjusted. In this embodiment, the upper angle 37 is provided with a plurality of fixing holes 40 and the lower angle 38 is provided with the fixing screw holes 39. However, in this case, the upper angle 37 and the lower angle 38 are also included. For fixing at an arbitrary overlapping position, a fixing screw hole 39 or a fixing hole 40 for passing a screw 42 fastened corresponding to the fixing screw hole 39 is provided in one of the upper angle 37 and the lower angle 38, On the other side, a plurality of fixing holes 40 corresponding to the fixing screw holes 39 or a plurality of fixing screw holes 39 corresponding to the fixing holes 40 are provided, and a plurality of fixing holes 40 provided on the other side of the upper angle 37 and the lower angle 38 are provided.
