Third Embodiment In the scent preparation device of the second embodiment, the comfort / control device 30 of FIG. 2 sets the compounding ratio for the user to supply the individual aroma undiluted solution H which is the basis of the scent beforehand. The scent that is arbitrarily designated and mixed in the designated mixing ratio can be released to the living space 1. However, with such a scent preparation device, it is possible to produce only a scent having a composition ratio preset by the user,
Alternatively, although it is possible to prepare a scent having only a composition ratio in accordance with a program created by a user, it is not possible to automatically generate a scent that is surprising. In view of this, the third embodiment provides a scent adjusting device capable of automatically generating a scent rich in surprise. First, the principle of scent preparation will be described with reference to FIG.

FIG. 6 is a diagram showing the principle of scent preparation in the scent preparation device of the third embodiment. In this figure, a scent adjusting unit 13A, which is an output device provided on the left side of the living space 1, corresponds to the scent adjusting device of FIG.
A scent sensor 70 as an input device is provided on the right side of the. The scent sensor 70 and the scent adjusting unit 13A are connected by the feedback path 33. In the case of automatically preparing a scent, a fragrance stock solution prepared by dissolving a plurality of fragrances in a solvent is prepared in advance.
By operating the supply device of each aroma stock solution H in the inside, controlling the initial supply amount of each aroma stock solution H, mixing those aroma stock solutions H,
The scent mixture in the living space 1 is prepared by outputting the mixture of scents by the means for releasing the scent into the living space 1. The scent mixture in the living space 1 uses the scent sensor 70 which is an input device,
The type, concentration, etc., which is the information of the scent in the living space 1, is detected. Information such as the type and concentration of the scent detected by the scent sensor 70 is fed back to the scent preparation unit 13A, which is a scent output device, and is used as an input for the next output. By repeating such an operation at regular intervals, the composition and concentration of the scent in the living space 1 can be automatically adjusted.

As described above, the method of repeating one's own output as one's own input is well known as a model of time change of prosperity and decline of living things in the living world. In this model, when the birth rate is 0 <X <1, the birth rate of the next generation is expressed by the following equation (1). _{X n + 1 = CX n (} 1-X n) ··· (1) where, C is a predetermined constant, X _n is the generation of fertility,
X _{n + 1} is the birth rate of the next generation. It is known that the formula (1) is well applied to species such as insects in which larvae become adults at the same time in one year.
(1), after assignment of one initial value, X _{n + 1} is reduced when X _n is too large, with the automatic adjustment function of X _{n + 1} when the X _n too small increases There is. Then, after inputting the initial value and the constant, the result cannot be predicted, and the result cannot be known unless the calculation is performed. Furthermore, the results will also differ greatly depending on how the significant figures in the calculation are taken. In this way, what follows a deterministic formula and whose behavior in the future cannot be predicted is known as chaos.

In this embodiment, the principle of time change of prosperity and decline of living things in the living world is applied to automatically adjust the scent of space. The olfactory sensation becomes paralyzed when the same odor continues, so by changing the scent concentration, type, composition, etc. by the above-mentioned automatic adjustment, olfactory numbness can be eliminated and a comfortable stimulus can be given. . FIG. 7 is a functional block diagram of a scent preparation device showing a third embodiment of the present invention constructed using the principle of FIG. This scent adjusting device operates in the same manner as in FIG.

An alcoholic solution of seeds is stored. Fragrance sensor 70
Uses, for example, the one having the same principle as the one in which the lipid bilayer film is provided on the crystal oscillator described in Document 3 above. This sensor detects fragrance molecules adsorbed on the lipid bilayer to cause a weight change, and detects this slight change as a change in frequency. The lipid of the lipid bilayer membrane used here is the synthetic lipid dioleoyl phosphate (DOPH) described in the above-mentioned reference 4 in which the phosphatidylcholine and phosphatidylethanolamine are mixed at 20% and DOPH. Only 3 types are used. Three types of scent sensors using these three types of lipids are prepared, and a scent sensor 70 having a plurality of sensors is provided in the living space 1 or the like.

Next, the operation of the scent adjusting device shown in FIG. 7 will be described. First, when the scent preparation unit 13A operates under the control of the scent preparation control unit 31, the three kinds of fragrance stock solutions H stored in the three stock solution tanks 41a to 41c in FIG. The liquid feed pumps 42a to 42c feed the pipe 44 to the pipe 44 in a preset amount, and the liquid is discharged from the discharge nozzle 45 to the aroma liquid concentrate absorber 50. The three kinds of the undiluted fragrance liquids H are absorbed and mixed in the undiluted fragrance liquid absorber 50. These aroma concentrate mixtures
It is volatilized and diffused forcibly by the blower 60 of FIG. 3, and is discharged from the chamber 46 to the living space 1.

Since the scent sensor 70 composed of three sensors made of three different lipid membranes is provided in the living space 1, the scent sensor 70 determines the type of scent present in the space. Different adsorption responses with respect to the concentration are obtained, and the responses unique to the three types of sensors are obtained. From the response pattern of the scent sensor 70 including these three types of sensors, the data processing unit 32 measures the concentration and type of scent in the living space 1, and the measurement result is sent to the scent preparation control unit 31 via the feedback path 33. Enter again. In this embodiment, such a process is repeated every 30 minutes. The scent molecules released into the living space 1 become approximately constant in the living space 1 by a stirring fan (not shown) in the living space 1, but natural convection, a temperature difference between the surfaces closing the space,
Due to unsteady causes such as leakage from the space gap and inflow of air, the state locally becomes slightly different with time.
Therefore, the measurement value of the scent sensor 70 is slightly different from the values of the scent type and the concentration specified by the scent preparation control unit 31. As a result, each time the measurement value passes through the feedback path 33, the change in the scent concentration increases or decreases. In this way, the user can automatically control the scent in the living space 1 without determining the type and concentration of the scent. In this embodiment, the scent preparation unit 13

The scent specified and mixed in the specified mixing ratio can be ejected into the living space 1.
However, in this type of scent adjusting device, the scent-generating fragrance liquid absorber 50, which is a base for scent generation, has a fixed structure and absorbs scent, so when changing to a scent with a new composition,
The previous scent remains for a long time, and it is difficult for the user to accurately reproduce the scent that the user wants to control due to the influence of the remaining scent. In order to accurately reproduce the scent that the user wants to control, maintenance such as replacement and cleaning of the fragrance stock solution absorber 50 is required.

Therefore, in the fifth embodiment, the aroma concentrate absorbent body 50 has a replaceable structure so that the newly prepared scent can be quickly and stably mixed with the previously prepared scent into the living space. We have realized what can be supplied and made it easy to maintain the equipment. FIG. 9 is a schematic configuration diagram of a scent preparation device showing a fifth embodiment of the present invention, in which elements common to those in FIG. 3 showing the second embodiment are designated by common reference numerals. There is. In this scent adjusting device, the fixed-type aroma stock solution absorber 50 of FIG.
It is composed of. The aroma undiluted solution absorber 51 is a flexible liquid absorbent such as a filter paper made of paper or a polymer material, and is capable of easily mixing, volatilizing and diffusing the absorbed aroma undiluted solution. That is, the aroma undiluted solution absorber 51 is in the form of a roll in which a long product is rolled, and the control signal of the comfort / control device 30 of FIG. It can be moved automatically or manually according to

In this type of scent adjusting device, the discharge nozzle 4
The undiluted fragrance liquid H released from 5 is absorbed and mixed in the undiluted fragrance liquid absorber 51. The aroma concentrate mixture is forcibly volatilized and diffused by the blower 60, mixed with the air to be sent into the room, and then sent from the chamber 46 to the living space 1 in FIG. When changing the previously set scent to the next scent, the used portion of the fragrance stock solution absorber 51 is wound around the winding roll 53, and the unused scent stock solution absorber 51 is positioned below the discharge nozzle 45. Good.

The fifth embodiment has the following advantages. For example, in the second embodiment, the aroma concentrate 50 is a fixed type, and since the substance to be absorbed is a scent, when changing to a scent of a new composition, the previous scent remains for a long time and remains. There were drawbacks such as being affected by the scent. On the other hand, since the aroma concentrate absorbent body 51 of the present embodiment has a replaceable structure, frequent replacement is unnecessary, the influence of the remaining scent used last time is eliminated, and the scent that the user wants to control is promptly changed. It can be faithfully reproduced. Furthermore, maintenance such as replacement and cleaning of the aroma concentrate absorbent body 51 in order to accurately reproduce the scent that the user wants to control becomes unnecessary.

The present invention is not limited to the above embodiment,
Various modifications are possible. The following are examples of such modifications. (I) In FIG. 1, the individual fragrance stock solutions H in the stock solution tanks 41a to 41d are sent to the pipes 44 by the liquid feed pumps 42a to 42d, individually absorbed by the individual fragrance stock solution absorbers, and volatilized and diffused. After that, they may be mixed.
As a result, substantially the same effect as that of the first embodiment can be obtained. (Ii) In FIG. 1, FIG. 3, FIG. 8, and FIG. 9, the aroma concentrate absorbents 50 and 51 do not have to be the porous material as in the above-mentioned embodiment. For example, even in the case of a plastic film, it is sufficient that the supplied aromatic undiluted solution H can be uniformly evaporated without spilling. Further, without using the liquid feed pumps 42a to 42d, the stock solution tanks 41a to 41d
d is installed at a position higher than the fragrance stock solution absorbers 50, 51, and the electromagnetic valve 43 is used by using the dropping force of the individual fragrance stock solution H.
It is also possible to adjust the supply amount of the individual aroma stock solution H with a to 43d. (Iii) In FIG. 3, the scent sensor 70 is composed of the sensor of the above-mentioned document 1, but detects the weight change of the chemical substance attached to the crystal oscillator described in the above-mentioned documents 2, 3 and the like by the change of the frequency. The scent sensor of the type, the lipid membrane sensor described in the above-mentioned Document 5 or the like may be used. (Iv) In FIG. 7, the scent sensor 70 has a plurality of adsorbing capacities for scented substances in order to detect the scent component and concentration in the space in addition to detecting the scent in the space using a lipid film. Sensors using different membranes may be used. (V) In FIG. 8, the micro electric heater 82c is used as a pressurizing means for increasing the pressure necessary for releasing the aromatic liquid concentrate H. However, as described in Document 6, the pressurization is performed. The means only needs to generate a pressure in the nozzle 82b, and thus other pressure increasing means such as an ultrasonic transducer may be used. (Vi) In FIG. 9, the undiluted scented liquid absorbent body 51 need not be a roll shape but may be a long one, and may be, for example, a folded shape. In addition, if the structure is interchangeable, various shapes can be adopted.
