[Detailed description of the invention]

[0001]

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 liquid perfume transport tube having one end inserted into the perfume container and the other end connected to an intermediate container, A minute flow pump interposed in the conveying tube, a means for feeding air into the intermediate container, a scented air passage leading from the intermediate container to the scented atmosphere, and a scented air passage. A scent generator comprising an interposed valve means.

[0008]

The micro flow pump pumps the liquid perfume in the perfume container as it is (without diluting with a solvent, etc.) to the intermediate container at the end of the tube in a very small amount (about 0.01 to 120 ml / Hr). The intermediate container is a closed container that is shielded from the surrounding atmosphere. The liquid fragrance introduced little by little into the intermediate container evaporates due to a partial pressure difference, and the container is filled with highly concentrated scented air. By sending air separately to the intermediate container,
The scented air is conveyed to the scented atmosphere via the scented air supply path.

As described above, since the liquid fragrance is continuously vaporized little by little in the intermediate container, and is mixed with the carrier air and released into the atmosphere to be aroma, the fragrance is directly converted from the liquid fragrance into the atmosphere. The diffusion into the atmosphere is performed more favorably and the concentration becomes uniform, as compared with the case of releasing.
The operation of the valve installed in the scented air supply passage makes it easy to control the start and stop of scented air, and also controls the concentration of scented air by controlling the amount of carrier air supplied as a carrier. Can be. Therefore, it is easy to control the fragrance concentration in the atmosphere.

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,
Air is sent to the intermediate container 4, the fragrance transport tube 5 having one end connected to the fragrance container 3 and the other end connected to the intermediate container 4, the minute flow pump 6 interposed in the fragrance transport tube 5, and the intermediate container 4. The scented air supply passage 8 communicates with the scented atmosphere in the duct 1 from the intermediate container 4, and a valve 9 interposed in the scented air supply passage 8.

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 entry pipe 10 with a check valve penetrate the lid of the container 3 in an airtight manner. ing. The air entry tube 10 is provided to alleviate the pressure reduction in the container due to the extraction of the liquid fragrance. An open / close valve 11 is attached to the tube 5.

The minute flow pump 6 is attached to the tube 5 near the intermediate container 4 in the illustrated example, and the pump 6 functions as a check valve while the pump is stopped.
This micro flow pump 6 is a device available on the market.
In the illustrated example, a roller pump is used in which the liquid in the tube is unidirectionally pushed by a roller that rotates unidirectionally while sandwiching the flexible tube from the outside. 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 small flow pump 6 available in the market,
In addition to roller pumps, there are also those called tube pumps and diaphragm pumps. In any case, it is preferable that this pump can control the flow rate in the range of 0.01 to 120 ml / Hr.

The intermediate container 4 is a closed container that is shielded from the surrounding atmosphere. An end of a tube 5 is inserted into the container 4, and a small amount of liquid fragrance is introduced into the container from this end by driving a pump 6. Is done.

On the other hand, the intermediate container 4 is connected to an air supply pipe 7 having a discharge port 12 opened in the container and a scented air supply path 8 having an exhaust port 13 opened in the container. In the illustrated example, the air supply pipe 7, the scented air supply path 8, and the tube 5 penetrate through the lid of the intermediate container 4 and are hermetically mounted.

The air supply pipe 7 is connected to an air supply device 14, and compressed air is discharged from the discharge port 12 into the container 4 by the operation of the air supply device 14. A high-performance filter 15 and a medium-performance filter 16 are interposed in the air supply pipe 7, and purified compressed air is introduced into the container 4 through these filters. A valve 17 is attached to the air supply pipe 7, and the amount of air supply is controlled by operating the valve 17.

The scented air supply passage 8 is for sending the fragrance vaporized in the intermediate container 4 to a required scented atmosphere (in the illustrated example, in the air in the duct 1). This scented air supply passage 8
Is provided with a valve 9, and the opening and closing device of the valve 9 starts and stops the scented air.

Reference numeral 18 denotes a control panel, which is operated by an operation command from the control panel 18 to open and close the valve 11 of the tube 5, start and stop the minute flow rate pump 6, start and stop the pump 14 in the air supply path, and operate the valve.
