Description

Detailed Description of the Invention "Industrial Application Field" This invention provides a comfortable environment by supplying fragrance to spaces where people are active, such as the interior spaces of buildings and the interior spaces of ships, aircraft, vehicles, etc. The present invention relates to a scent supply device for producing scents.

``Conventional technology'' In recent years, there has been increasing interest in scents as a means of improving the living environment, and indoor air fresheners are being used to mask bad odors such as those caused by cigarettes. The excellent physiological and psychological effects are also being considered.

Traditionally, the physiological and psychological effects of scents on humans have been known empirically as "aromatherapy," and more recently, it has been discovered through research into concomitant negative fluctuations (CNv) in human brain waves. , certain scents have an arousal and sedative effect on humans,
It has been proven that it has bioactive effects. Experiments have also confirmed that supplying scents such as lemon to the conditioned air in conference rooms and key manager rooms can improve the efficiency of meetings and reduce the number of missed batches in key manager rooms.

In this way, there are scents such as lemon that activate the mind and have the effect of awakening (waking up) and activating circulatory function, and lavender that calms the mind and relieves stress. , which has the effect of relieving anxiety and antidepressant, etc., rosemary which has the effect of increasing appetite and relaxing, and phytonchisoto which has the effect of sterilizing bacteria harmful to the human body. Some scents have the effect of restoring health, and it is believed that effectively utilizing the effects of these scents will help improve the living environment.

Incidentally, fragrances are generally liquids, and the scent of such fragrances is usually composed of several to hundreds of types of aroma components, and each aroma component differs in its volatility.

For this reason, fragrances containing each aroma component are naturally vaporized.
In this case, the easily volatile aroma components will evaporate first, making it difficult to generate the desired aroma.
1. The ingredients and composition of the scent that is generated changes over time, resulting in changes in the quality of the scent.

Therefore, recently, the ratio of each aroma component contained in the scent generated by forced vaporization of fragrances is always kept constant, and the scent is mixed with conditioned air and supplied indoors, so that the whole room can be filled. A scent fJIG feeder configured to provide uniform distribution has been devised.

Such a fragrance supply device, as shown in FIG. It is composed of a fragrance storage tank 3, a fragrance supply pump 4, an air supply 1, a supply blower 5, a fragrance vaporization chamber 6, and an invactor 6a.

The fragrance vaporization chamber 6 has two incense 11 supply pipes 7 for supplying the fragrance in the fragrance storage tank 3, an air supply pipe 8 for supplying air, and an air conditioning duct 2. An air conditioning duct connecting pipe 9 is connected to the supply pipe 7 to supply the vaporized fragrance to the air conditioning duct 1-2. , J, and a flow rate adjustment valve lO are provided, and the air supply pipe 8 is provided with an air supply blower 5 and a flow rate adjustment valve 11.

Furthermore, the fragrance supply pump 4, the flow rate adjustment valve 10, the air supply blower 5, and the flow rate adjustment valve 11 are all connected to a control device 12, and this control device controls the fragrance supply pump 4 and the fragrance supply blower. 5 is controlled, and the amount of fragrance supplied to the air conditioning duct 2 is adjusted by controlling the opening degree of the flow rate regulating valve 10.11. In addition, these fragrance supply pump 4, flow rate adjustment valve IO1 air supply blower 5, and flow rate adjustment valve II are as follows:
It can also be operated in conjunction with the air conditioner 1.

Further, in the fragrance vaporization chamber 6, there is provided a mechanism for forcibly vaporizing the fragrance by converting it into a liquid.

As for such a misting mechanism, there is a spray type that uses the principle of an atomizer, or an ultrasonic type that uses ultrasonic waves to create a mist. When supplied to a room from the air conditioning outlet, it is diluted and diffused by the airflow and spread throughout the room. Therefore, at time t at a distance X from the air outlet (
In addition to x and t, the concentration C of the astringent scent is determined by the room temperature Tr and the temperature Ts of the supplied air.

Furi■, the concentration of the scent supplied C8, and a complex function expressed as C, C= f (Tr, Ts, V, Cs, x, t, C)
It is expressed as

Therefore, in order to adjust the scent concentration in the target room, it is considered necessary to know the scent state of the entire room by finding the function r.
Since it is extremely difficult to obtain , instead,
It is considered effective to install a sensor in the target room and approximately determine the scent state of the entire room based on the information from the sensor.

However, in the above-mentioned scent supply devices, the purpose is to uniformly add scent to one or more target spaces, so it is necessary to add scent uniformly to each space or to each area within the same space. There was a problem in that it was not possible to intentionally create a difference in scent concentration.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a scent supply device that can intentionally create a difference in scent concentration for each individual space or for each region within the same space. It is an object.

"Means for Solving the Problems" The scent supply device of the present invention is a scent supply device configured to mix fragrance with conditioned air and supply it to a predetermined space. Consisting of a scent generating unit provided at each outlet that discharges conditioned air to the area, and one or more scent generating control units that individually control the amount of scent generated from these multiple scent generating units. This is what is being done.

Fragrance here refers to various fragrances that not only smell good and improve your mood, but also have physiological and psychological effects, such as recovering from fatigue, calming the mind, and energizing the body. It also includes aromatic substances that have bactericidal and physiologically active effects, such as phytoncide emitted by plants.

"Function" The number supply device of the present invention includes a scent generating section provided at each outlet for discharging conditioned air to a plurality of spaces or a plurality of regions within the same space, and a scent generating section provided from each of the plurality of scent generating sections. Since it is composed of one or more scent generation control sections that individually control the amount of scent generation, the scent generation section that generates the scent can be changed for each scent generation section.
Thereby, it is possible to intentionally create differences in scent concentration for each individual space or for each area within the same space.

"Example" Hereinafter, the fragrance supply device of the present invention will be described with reference to FIGS. 1 to 5.

As shown in FIG. 1, the scent supply device of this embodiment has a scent generating section 2 at each outlet 40 for conditioned air provided at a plurality of different positions in a room 25 to which scent is to be supplied.
3, and a scent generation control section 4 that individually controls the amount of scent generated by each of these scent generation sections 23.
1 is provided in the lower storage section 42 near the wall of the room 25.

] 2. Each outlet 40 is connected to an air conditioning duct 30 installed in the ceiling of the room 25, and this air conditioning duct 30 is connected to an air conditioner 22 installed in a machine room (not shown) or the like. is connected to. The fragrance generation control unit 4I described in - is connected to the air conditioner 22 main body and sends an operation signal for the air conditioner 22 main body.
or is connected to the air conditioning control device (not shown) of the air conditioner 22 to output the control signal of the air conditioning control device as control information to each scent generating unit 23. It is designed to be taken out as .

Additionally, sensors 26 are installed at various locations such as on the wall 43 and desk 44 of the foot room 25, and the information detected by these sensors 26 is sent to the scent generation control unit 41.
Based on the information, the fragrance generation control unit 41
calculates the amount of scent generated from each scent generating section 23. As each of these sensors 26, a scent sensor that detects the concentration of the scent itself is most suitable, or a temperature sensor may be used instead since the scent moves with the conditioned air and its diffusion state is also a function of temperature. It is possible.

However, in that case, there will be no lighting,
There are heat sources such as A equipment and people, and these heat sources reduce the accuracy of the approximation. Therefore, it is desirable to increase the accuracy by using two types of sensors together, and by increasing the number of sensors. It is desirable to further improve the accuracy. And room 25 where fragrance should be supplied
Since the state of the scent in a room is always changing, in order to accurately know the state of change, change the temperature and scent concentration of the conditioned air supplied to the room 25, and change the conditioned air and A very effective means is to utilize the difference in patterns between the scent generation source (the air conditioner 22 and the scent generation section 23) and the information from the sensor 26 installed in the room 25.

Furthermore, when a fragrance is supplied to the second room 25 in this manner, the smell becomes more perceivable when the humidity of the room 25 becomes high, and depending on the type of fragrance, it may not cause discomfort when the temperature rises. be.

Therefore, when using this scent supply device, humidity sensors are installed in addition to temperature sensors at required locations in the room 25 to which the scent is to be supplied. It is desirable to select the most suitable scent suitable for the temperature and humidity by sensing the temperature and humidity, and to control the supply of that scent at the optimal concentration.

Furthermore, in addition to the above-mentioned temperature sensor and humidity sensor, the room 25 to which fragrance is to be supplied may be provided with sensors that detect airflow, radiant heat, the number of people, their activity status, etc. , the room 25 is detected by each of these sensors.
It is possible to grasp the overall state of the air conditioner and control the amount of scent generation from each scent generation section 23 based on the comprehensive state.

In such a scent supply device, if the distance between each sensor 26 and the scent generation control section 41 is short, it is possible to connect each sensor 26 and the scent generation control section 41 directly; If the sensor 26 and the scent generation control section 4I are separated from each other, if you try to connect each sensor 26 and the scent generation control section 4I directly, you will need to draw a long conductor line that transmits the raw information from each sensor 26. This is undesirable because it causes a decrease in the S/N ratio. Therefore, in such a case, it is desirable to convert the detection signals from each sensor 26 into control signals and then send them to the fragrance generation control section 41 to solve problems such as a decrease in the S/N ratio. And in that case ("
, a signal converter for converting and processing the detection signal of each sensor 26 is built into each sensor 26, and the signal converter and the scent generation control section 4I are directly connected via a digital or analog communication line, or In between, it is necessary to provide a transmitter that converts the control signal into a transmission signal and transmits it, and a receiver that converts the transmission signal into a control signal. In addition,"
- The communication line may be wired or wireless, but specifically wired communication lines include voltage signal lines, non-voltage signal lines, telephone lines, and television lines. In addition to computer lines, internal digital lines, and dedicated digital lines, it is also possible to send signals using the FM method to the power supply line, and wireless communication lines include the FM method, Δ2M method, etc. There are various methods.
