[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a scent generation device for adding a scent to air-conditioned air or indoor air by leaking and vaporizing liquid fragrances in minute amounts.

[0002]

[Prior Art]

 Recently, scent air conditioning, which gives scents to air-conditioned spaces, has attracted attention, and various fragrances and scent applying means have been proposed. Of these, the method of spraying the fragrance using a spray nozzle is the most representative of the scent imparting means. In this case, in order to control the perfume concentration to be 1 ppm or less in the room air, which is said to have an appropriate perfume concentration, the perfume is diluted with pure water or a solvent such as alcohol and then sprayed.

[0003]

[Problems to be solved by the device]

 In the method of spraying the fragrance into the air, since the minimum amount that can be sprayed is limited, the liquid fragrance is diluted with a solvent as described above and sprayed. Alcohols, which are the most typical solvents, are dangerous. There is a problem with.

In order to avoid this, it is often diluted with pure water, but since the evaporation rate of water is slow, the problem of dripping occurs due to insufficient evaporation, and water spraying has a latent heat load. It is accompanied by the problem of increased temperature and changes in humidity.

Although many of the fragrances are oil-based, oil-based fragrances are difficult to mix with water, so they are mixed with a surfactant. However, the surfactants blow out into the living room. It's not very pleasant.

The present invention is intended to solve the above-mentioned problems in imparting a scent to an air-conditioned space.

[0007]

[Means for Solving the Problems]

 According to the present invention, a perfume container containing a liquid perfume, a perfume transport tube having one end inserted into the perfume container and the other end connected to the perfume leaking part, and the perfume transport tube provided with the perfume transport tube. Provided is a fragrance generating device comprising the minute variable flow pump described above and a heat supply means for applying heat to the fragrance leaking portion.

[0008]

[Action]

 The micro variable flow pump conveys the liquid perfume in the perfume container as it is (without diluting it with a solvent etc.) to the perfume leaking part at the end of the tube in very small amounts (0.01 to 120 ml / Hr). As a result, liquid perfume oozes out from the perfume leaking portion little by little. The liquid perfume that has exuded to the perfume leaking part is heated by the heat supply means to accelerate the volatilization of the perfume. As a result, a high concentration of scented air is obtained, and this scented air diffuses into the surrounding air and imparts a scent to the conditioned air.

【Example】

 FIG. 1 shows an embodiment of the device of the present invention, and shows an example in which the scent generation device of the present invention is connected to duct 1 that conveys conditioned air indoors. In this example, the fragrance generating device of the present invention is a fragrance container 3 containing a liquid fragrance 2, and one end 4 is inserted into the fragrance container 3 and the other end 5 is connected to the fragrance leaking part 6 to convey the fragrance. It is composed of a tube 7, a minute variable flow rate pump 8 interposed in the flavor conveying tube 7, and a means for supplying heat to the flavor leaking portion 6.

The perfume container 3 is a bottle for hermetically containing the liquid perfume 2, and a tube 7 for drawing out the liquid perfume and an air inlet pipe 10 with a check valve are hermetically penetrated through the lid of the container 3. ing. The air entry pipe 10 is for alleviating the pressure reduction in the container due to the liquid perfume pumping out. An open / close valve 11 is attached to the tube 7.

The minute variable flow rate pump 8 is attached to the tube 7 near the fragrance leaking portion 6 in the illustrated example, and the pump 8 serves as a check valve while the pump is stopped. This micro variable flow pump 8 is a device available on the market. In the example shown in the figure, the liquid in the tube is unidirectionally pushed out by a roller that rotates in one direction while sandwiching the flexible tube from the outside. I am using a roller pump. The roller is rotated by a motor, but the amount of extruded liquid can be finely adjusted by adjusting the rotation speed of the roller. In addition, in addition to the roller pump, the micro variable flow rate pump 8 available on the market is also called a tube pump or a diaphragm pump.

A liquid filter cassette 12 is replaceably attached to the tube 7. In the illustrated example, the micro variable flow pump 8 is provided in the tube 7 at the suction side position. A check valve 14 is attached to the tube 7 near the fragrance leaking portion 6.

A perfume leaking part 6 is attached to a discharge side tube end 5 of the micro variable flow pump 8. The perfume leaking part 6 attached to the inside of the duct 1 is made of a block of porous material in the example of FIG. 1, and the tube end 5 is connected to this block. For this reason, the liquid that leaks from the tube end 5 in small amounts leaches into the block and is impregnated, so that the surface of the block is moistened.

Further, this porous block is configured to generate heat when energized. That is, the porous block itself is made of a material having a high electric resistance, and when the electrode 9 is attached to the material, the block itself generates heat when energized. A controlled amount of electric current is applied to the electrode 9 by the controller 13.

In the apparatus of FIG. 1 configured in this way, when the opening / closing valve 11 is opened to operate the minute variable flow rate pump 8 and the perfume leakage section 6 is energized by the controller 13, the perfume leakage section 6 leaks little by little. The perfume liquid is heated by the Joule heat generated by energization to promote vaporization, and this perfume air diffuses into the air flow in the duct. Therefore, the conditioned air flowing in the duct is appropriately diffused and perfused and introduced into the air-conditioned space. When the perfume is stopped, the minute variable flow pump 8 stops energizing the perfume leaking part 6, but the check valve 14 prevents the perfume staying in the tube 7 from flowing out to the perfume leaking part 6.

FIG. 2 shows that a minute variable flow pump 8 is attached to a tube 7 close to the scent leaking part 6, and when this pump 8 is at rest, it acts as a check valve, and at the same time, the scent leaks. The device of the present invention is shown in which a block 61 made of a porous material is used for the portion 6 and heat is applied to the fragrance leakage portion 6 by blowing hot air. In FIG. 2, the members with the same reference numerals as in FIG. 1 are the same as those described in FIG.

Indicates. In other words, a small amount of liquid perfume controlled from the tube end 5 by the minute variable flow pump 8 is dropped onto the tray 63, and the liquid perfume is vaporized by hot air at a speed almost equal to or higher than the dropping amount. Is.

FIG. 6 shows a scent generating device of the present invention having the same configuration as the device of FIG. 5, except that a heater 17 is used instead of the hot air blowing nozzle. The heater 17 is arranged in the duct upstream of the tray 63 (upstream of the air flow flowing in the duct 1). As a result, the air heated by the heater 17 is conveyed by the air flow in the duct so as to pass through the portion of the saucer 63, and in the process of passing through it, heats the liquid perfume and at the same time provides an opportunity for contact with new air. give. A controller 18 controls the amount of electricity supplied to the heater 17 and the start / stop of the heater 17.

FIG. 7 shows a device of the present invention in which heat is supplied by using a planar heating element that generates heat when energized. There is known a sheet heating element in which a resistor is placed in a resin sheet and the entire surface of the sheet is heated by energizing this resistor. In this study, this sheet heating element 20 is used. The saucer 65 is laid under the saucer 65, and the controller 21 is used to heat the planar heating element 20 to heat the saucer 65. A small amount of liquid fragrance is dripped from the tube end 5 into the saucer 65, as in the case of the embodiments shown in FIGS. 5 and 6, and the fragrance vaporized by this heating diffuses into the air flow in the duct and is harmonized. Adds a scent to the air.
