Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device and a method for adding moisture and scent to treated air for air conditioning.

[0002]

2. Description of the Related Art Conventionally, in order to add moisture to air treated by an air conditioner, it has been practiced to add moisture to the treated air by using a water spray type humidifier. In addition, recently, a scent is also added to the treated air of an air conditioner. When humidifying or adding a scent in this way, use separate injection nozzles, and by injecting compressed air from the injection nozzles, the water from the water tank is sucked in and sprayed, and at the same time from another injection nozzle. By blowing out compressed air, the scent from the fragrance tank is sucked into the processing air.

[0003]

If a spray nozzle for adding a scent and a spray nozzle for adding a moisture are separately provided as in a conventional air conditioner, spray is performed after spraying the fragrance from the spray nozzle for adding a scent. There was a problem that some of the last fragrance remained in the nozzle, which deteriorated due to contact with air. In addition, although each scent addition nozzle and moisture addition injection nozzle have almost the same mechanism, they are provided separately,
This is not economically desirable because it requires a large space for arranging the device and doubles it. Therefore, an object of the present invention is to make it possible to use a single scent addition injection nozzle and a single moisture addition injection nozzle, and to make the apparatus economical and compact.

[0004]

In order to achieve the above object, the apparatus for adding moisture and scent according to the present invention can spray the moisture and scent with one nozzle. That is, the nozzle body was provided with two suction holes communicating with the compressed air passage, one of the suction holes was communicated with the fragrance tank, and the other was communicated with the water tank. In addition, the method of adding moisture and scent of the present invention is such that, as compressed air is jetted from one jet nozzle, scent and water are separately blown from two suction holes provided in the jet nozzle, and they are atomized. It was made to be able to be mixed in the process air of the air conditioner.

[0005]

With the above-described moisture and scent addition device or addition method, when adding moisture to the conditioned air, the on-off valve of the pipe line that connects the water tank and the suction hole of the nozzle body is opened to release compressed air from the nozzle. If it blows out, the inside of the nozzle becomes a negative pressure, and water can be sucked from the water tank and blown out in a mist form from the nozzle injection port. Similarly, when adding a scent to the conditioned air, if the opening / closing valve on the scent tank side is opened, the nozzle inhales and atomizes the fragrance and mixes it into the conditioned air as in the case of adding moisture. When adding both humidity and scent to the conditioned air, it is sufficient to open both open / close valves and blow out the compressed air from the nozzle. After blowing the fragrance from the nozzle, close the opening / closing valve on the side of the fragrance tank, open the opening / closing valve on the side of the water tank, and spray water from the nozzle to wash away the fragrance remaining in the nozzle. It is possible that the fragrance does not remain in the nozzle and deteriorate.

[0006]

Embodiments of the present invention will be described with reference to FIGS.
A nozzle 1 for blowing moisture and scent into the process air of an air conditioner is connected to a compressed air tank 3 via a pipe line 2 having an opening / closing valve A in the middle. Compressed air is supplied to the air tank 3 by a compressor 4, and a relief valve 5 is provided in the supply line. In the nozzle 1, the compressed air passage 1b communicating with the injection port 1a is communicated with the compressed air tank 3 through the pipe 2 and the compressed air is supplied to the nozzle 1 by opening the opening / closing valve A. ing.

The main body of the nozzle 1 is provided with two suction holes 6a and 6b communicating with the compressed air passage 1b, and one suction hole 6 is provided.
a is communicated with the fragrance tank 7 through a pipeline having an opening / closing valve B on the way. The other suction hole 6b communicates with the water tank 8 via a conduit having an opening / closing valve C on the way. Then, when the air flows through the compressed air passage 1b of the nozzle 1, the inside of the nozzle becomes negative pressure, and the scent or water can be sucked from the two suction holes 6a and 6b, and can be ejected in a mist form from the ejection port 1a. There is.

The moisture and scent addition device shown in FIG. 1 has, for example, three routes from the compressed air tank 3 to the nozzle side, so that it can be adapted to an air conditioner having three routes.
In this way, separate water tanks 8 for the three nozzles 1 are provided.
And the perfume tank 7 are in communication with each other, but the water tank 1
In one case, the three nozzles may be communicated with each other through separate conduits. Even if the water tank is also used for three nozzles, a separate fragrance tank can be connected to each nozzle to add three kinds of fragrance to one air conditioning system.

The method of adding moisture and scent is, for example, using the above-mentioned adding device, and an opening / closing valve B corresponding to the fragrance tank 7 or the water tank 8 communicating with the nozzle at the position to be added,
By opening C and injecting compressed air from the nozzle 1, fragrance or water can be sucked from the two suction holes 6a and 6b of the nozzle to add moisture or fragrance to the conditioned air. Of course, by opening both on-off valves, moisture and scent can be added at the same time. Then, after the addition of the scent is completed, water is sucked and sprayed from the suction hole 6b of the nozzle to wash the fragrance remaining in the nozzle 1 so that the fragrance does not remain and deteriorate. .

[0010]

According to the present invention, one nozzle serves both as a moisture adding device and a scent adding device, and the device can be made compact and economical. Further, the fragrance remaining in the nozzle can be washed by adding moisture to the nozzle, and the problem that the remaining fragrance deteriorates can be eliminated.
