[Detailed description of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scent generator for adding a scent to conditioned air or indoor air by leaking and vaporizing a small amount of liquid fragrance.

[0002]

2. Description of the Related Art Recently, scent air conditioning for giving a scent to an air-conditioned space has attracted attention, and various fragrances and scent giving means have been proposed. Among these, the method of spraying a fragrance using a spray nozzle is the most typical one in terms of the fragrance imparting means. In this case, the fragrance is generally sprayed after being diluted with a solvent such as pure water or alcohol in order to control the fragrance concentration in the indoor air to 1 ppm or less, which is said to be an appropriate fragrance concentration.

[0003]

In the method of spraying fragrance into the air, there is a limit to the minimum amount that can be sprayed. Therefore, the liquid fragrance is diluted with a solvent or the like as described above and sprayed. Alcohols, which are excellent solvents, have a problem that they are dangerous.

In order to avoid this, the water is often diluted with pure water. However, the evaporation rate of the water is low, so that the water does not evaporate sufficiently and a problem of dripping occurs. There is the problem of increasing or causing humidity changes.

[0005] Furthermore, there are many oil-based flavors, but oil-based flavors are mixed with water because they are hard to mix with water.
Not very pleasant.

[0006] The present invention is intended to solve the above-mentioned problems when adding a scent to an air-conditioned space.

[0007]

According to the present invention, a perfume container containing a liquid perfume, a perfume leakage container having a gas-permeable material layer on an upper surface, one end of the perfume container, and the other end of the perfume container. A perfume transport tube connected to the leakage container, a micro flow pump interposed in the perfume transport tube, a means for feeding air to the perfume leakage container, and a means for exhausting air from the perfume leakage container And a scent generator comprising:

[0008]

The micro flow pump pumps the liquid perfume in the perfume container as it is (without diluting with a solvent, etc.) to the perfume leakage container at the end of the tube in a very small amount (0.01 to 120 ml / Hr). The liquid fragrance, which is gradually discharged into the fragrance leakage container, evaporates in this container, and the fragrance air having a high concentration fills the container, and a part of the fragrance air leaks to the outside through the gas-permeable material layer. When a scent is imparted to the conditioned air, air is sent into the fragrance leakage container by the air sending means. As a result, the scented air in the container is conveyed and discharged to the outside from the gas-permeable material layer while the incoming air becomes a carrier and mixes with the carrier. When the scent application is stopped, the scented air in the fragrance leakage container is forcibly discharged from the system by the exhaust means. The concentration of the scent to be imparted can be controlled by adjusting the amount of air supplied or the amount of exhaust air.

[0009]

FIG. 1 shows an embodiment of the present invention, in which the scent generator of the present invention is connected to a duct 1 for conveying conditioned air into a room. In this embodiment, the scent generator of the present invention comprises a fragrance container 3 containing a liquid fragrance 2,
A fragrance leakage container 4 having a gas permeable material layer on its upper surface, a fragrance transport tube 5 having one end connected to the fragrance leakage container 4 and the other end connected to the fragrance leakage container 4, and a minute flow rate interposed in the fragrance transport tube 5 A pump 6, an air supply system 7 for supplying air to the fragrance leakage container 4, and an exhaust system 8 for evacuating air from the fragrance leakage container 4 are provided.

The fragrance container 3 is a bottle for airtightly storing the liquid fragrance 2, and a tube 5 for extracting the liquid fragrance and an air inlet tube 9 with a check valve are hermetically pierced through the lid of the container 3. ing. The air entry tube 9 is for alleviating the pressure reduction in the container due to the extraction of the liquid fragrance. An on-off valve 10 is attached to the tube 5.

The minute flow pump 6 is attached to the tube 5 near the fragrance leakage container 4 in the illustrated example, and the pump 6 functions as a check valve while the pump is stopped. The micro flow pump 6 is a commercially available device. In the example shown in the figure, a roller that unidirectionally rotates while exposing the flexible tube from outside is used to extrude the liquid in the tube unidirectionally. You are using a pump. The roller is rotated by a motor, but the amount of the extruded liquid can be minutely adjusted by adjusting the rotation speed of the roller. In addition, as such a minute flow rate pump 6 available in the market, there is a so-called tube pump or diaphragm pump in addition to a roller pump. In any case, it is preferable that this pump can control the flow rate in the range of 0.01 to 120 ml / Hr.

A liquid filter cassette 11 is replaceably mounted on the tube 5. In the illustrated example, the minute flow pump 6 is used.
This is interposed in the tube 5 at the suction side position.

The end of the tube 5 near the micro flow pump 6 is connected to the fragrance leakage container 4. In FIG. 1, a minute flow rate pump 6 is installed outside the duct 1, and a fragrance leakage container 4 is installed inside the duct 1.

As shown in FIG. 2, the fragrance leakage container 4 has a gas permeable material layer 13 on its upper surface. In the illustrated example, a gas permeable material layer 13 is attached to the lid of the container 4. As the gas permeable material layer 13, a filter material used for filtering air is used, but a porous ceramic plate, a porous resin, a fiber layer, or the like can also be used. An end of the tube 5 is inserted into the container 4, and a small amount of liquid fragrance is introduced from this end.

On the other hand, the fragrance leakage container 4 is connected to an air supply pipe 7 having an air supply port 14 opened in the container and an exhaust pipe 8 having an intake port 15 opened in the container. The air line 7 is connected to an air supply 16 as seen in FIG. The operation of the air supply device 16 causes the compressed air to be discharged from the air supply port 14 into the container 4. A high-performance filter 17 and a medium-performance filter 18 are interposed in the air supply pipe 7, and purified compressed air is introduced into the container 4 through these filters. The exhaust pipe 8 is connected to an exhaust device 19, and the exhaust gas sucked from inside the container 4 is exhausted from the exhaust port 20 to the outside by driving the exhaust device 19.

In the apparatus of FIG. 1 configured as described above, when the on-off valve 10 is opened and the minute flow rate pump 6 is operated, a small amount of liquid fragrance is introduced into the fragrance leakage container 4 in a liquid state. The liquid fragrance introduced into the container 4 evaporates here due to the partial pressure difference and fills the container 4. The air supply device 16 is operated when the scent imparting operation is performed, and the exhaust device 19 is operated when the operation is stopped. In the scent imparting operation in which the air supply device 16 is operated, the scented air filled in the container 4 is carried out from the gas permeable material layer 13 to the conditioned air as the carrier air, and the scent is imparted to the conditioned air. . By operating the exhaust device 20, the leakage of the scent can be stopped immediately.

In the above embodiment, an example is shown in which the fragrance leakage container 4 is disposed in the duct 1. However, the fragrance leakage container 4 can be disposed in an air conditioner or, in some cases, in an air-conditioned space. .

[0018]

According to the scent generating device of the present invention having the above-described structure, the amount of the liquid fragrance itself can be adjusted to a very small amount by the minute flow rate pump, and the fragrance is not diluted with the solvent or water. It is possible to control an appropriate concentration of the flavor in the air. In addition, the control of incense start / stop and the incense concentration are easy, and handling is also easy. From this, an effective scent air conditioner that can replace the conventional spray method can be realized.
