BEST MODE FOR CARRYING OUT THE INVENTION

[0016] Hereinafter, actual forms of the present invention will be described with reference to the accompanying drawings. Figure 1 shows the present invention. 2 is a plan view of a chemical transpiration apparatus according to an embodiment of the present invention, and FIG. 2 is a side view partially showing the AA cross section of FIG.

As shown in FIGS. 1 and 2, the chemical evaporation apparatus 1 includes an apparatus main body 2 composed of a base body 10 and a cover portion 20, and a carrier 4 that is detachably accommodated inside the apparatus main body 2. And a light source 6 disposed inside the apparatus main body 2.

The base 10 is formed in a container shape from a light reflective material, and the upper opening is covered with a lid member 11. The light reflective material is not particularly limited as long as it is a material having visible light reflectivity. For example, a white pigment or a dye is dispersed in various resins such as an acrylic resin, a polyethylene resin, and a polycarbonate resin. And metal materials such as stainless steel and aluminum.

[0019] The lid member 11 can be formed of a resin having excellent heat resistance and electrical insulation, and includes a storage portion 12 that can store the carrier 4 by being partially recessed. A metal bottomed cylindrical heat transfer body 13 is fitted to the outer peripheral surface of the housing part 12, and the bottom surface of the bottom part of the heat transfer body 13 has a planar shape made of an electric heater such as a PTC heater. The heating element 14 is installed in close contact.

[0020] In addition, the base 10 has a discharge port 10a formed at the bottom, and the light source 6 is disposed so as to emit a drowsiness light downward through the discharge port 10a. Awakening light refers to light that causes a sleep-inducing action, and is light that has lower illuminance than light intended for normal illumination. Specific illuminance of the sleeping light will be described later.

In the present embodiment, a green light emitting diode is used as the light source 6 that emits the sleeping light, but other lighting devices such as a fluorescent lamp, a neon tube, and an incandescent bulb may be used.

[0022] A power plug 16 and a switch 17 are provided on the side surface of the base 10, and the heating element 14 and the light source 6 can be energized via the power plug 16. In the present embodiment, the operation of the switch 17 allows the power S configured to energize the heating element 14 and the light source 6 in a body, and the energization of the heating element 14 and the light source 6 can be performed individually. You may comprise as follows.

[0023] The cover portion 20 is made of a light-transmitting material, is disposed so as to cover the entire base 10, and the power plug 16 and the switch 17 protrude through the openings 20a and 20b, respectively. light The transmissive material is not particularly limited as long as it is a material having at least visible light translucency so that the sleeping light can be visually recognized outside. For example, acrylic, polycarbonate, polypropylene, polyvinyl chloride vinyl, etc. Examples of such a light transmissive resin, ceramics, glass, and the like, and a light semi-transmissive material such as a resin in which an appropriate amount of a pigment or a dye is dispersed in these resins, or polished glass are also included.

[0024] Positioning of the base body 10 with respect to the cover part 20 is performed by fitting the power plug 16 into the opening 20a. In this state, there is a gap between the base body 10 and the cover part 20 over the whole. It is formed. The cover part 20 includes a cap 21 that detachably covers the upper part of the base body 10, and the carrier 4 can be accommodated in the accommodating part 12 with the cap 21 removed. A transpiration port 22 for evaporating the medicine of the carrier 4 to the outside is formed immediately above the accommodating portion 12 in the cap 21. A plurality of vent holes 23 are formed on the side surface of the cover part 20, and outside air is introduced between the base body 10 and the cover part 20 as the medicine evaporates from the evaporating hole 22.

[0025] The carrier 4 is a rod-like member made of felt, pulp, or the like, and is accommodated in the accommodating portion 12 so that the tip portion protrudes slightly. The carrier 4 can be impregnated with various liquid chemicals such as insecticides, bactericides, fragrances, deodorants and the like containing additives as appropriate. Use a product impregnated with a chemical containing at least the resulting fragrance component. As such a fragrance component, woody fragrances such as “sandalwood” and “pine” are particularly suitable.

[0026] In addition to felt and pulp, the material of the carrier 4 is cotton, rayon, acetate, synthetic resin (polyethylene, polypropylene, polyethylene + polypropylene mixture, polyethylene terephthalate, melamine, etc.), non-woven fabric, asbestos, inorganic molding, etc. In particular, a felt core, an unglazed core, a pulp core, a synthetic resin core, or an inorganic molded core is preferred. In addition, the shape of the carrier 4 is not limited to the rod-like shape as in the present embodiment, and may be various shapes such as a flat plate shape and a ring shape.

[0027] According to the chemical evaporation apparatus 1 having the above-described configuration, the power plug 16 is connected to an outlet installed on the wall surface of a home or office in a state where the carrier 4 is accommodated in the accommodating portion 12 of the apparatus body 2. By inserting, the heating element 14 and the light source 6 can be energized. The heating element 14 heats the carrier 4 via the heat transfer body 13 and the accommodating portion 12. As a result, evaporation of the aroma component impregnated in the support 4 is promoted, and the evaporated aroma component is evaporated to the outside through the evaporation port 22.

[0029] Further, from the light source 6, the sleeping light is emitted between the base 10 and the cover part 20 from the bottom of the base 10 downward. This slumber light passes through the cover part 20 made of a light-transmitting material while being repeatedly reflected on the surface of the base substance 10 made of a light-reflective material in the gap between the base body 10 and the cover part 20, thereby Released from the whole to the outside.

[0030] As described above, the drug transpiration apparatus 1 of the present embodiment can effectively enhance the arousal action by the synergistic effect of the arousal action by the transpiration of the aromatic component and the arousal action by the release of the arousal light. is there.

[0031] According to the results of experiments conducted by the present inventors described later, it has been clarified that a remarkable arousal effect can be obtained by a combination of the arousal light having a specific hue and illuminance and a specific aroma component. That is, the hue of the sleeping light transmitted through the cover part 20 is more preferably a hue number 11 to 13 (green) which is preferably a hue number of 7 to 15 (yellow to dark green) in the PCCS hue ring. On the other hand, if the light intensity of the hypnotic light is too large, it may interfere with the hypnotic effect, while if it is too small, the effect of combining the hypnotic light with fragrance is difficult to obtain. Is more preferred to be 11 to 23 lux. Here, the illuminance of the sleeping light is the position 5 cm away from the position P closest to the light source 6 on the cover 20 surface of the chemical transpiration device 1 when the ambient illumination is 6 lux or less. In illuminance meter (part number "ANA-F9", TOKYO

This is a value measured by PHOTO-ELECTRIC CO.LTD. The illuminance of the sleeping light can be configured to be adjustable by providing a light intensity adjustment means such as a switch that can control the number of light sources 6 to be energized and the amount of power to be applied to the light sources 6. The illuminance can be set to an optimal value according to the illuminance and individual differences.

[0032] By evaporating the woody perfume component under such arousal light having hue and illuminance, a particularly great arousal effect can be achieved. Examples of woody fragrances include sandalwood, cedarwood, pine, guaiatuk, benzoin, abies, lava, cypress, and black moji. Extraction of plant-derived essential oils exemplified in these The exit site is the trunk and root of the tree.

[0033] Such an optimal combination of the type of fragrance and the hue and intensity of the awakening light is not obtained by simply combining those individually optimized. In particular, the light with a hue number of 7 to 15 in the PCCS hue ring corresponds to the color of yellow to dark green and has been conventionally known as an obstacle to falling asleep. The knowledge that a remarkable arousal effect can be obtained by setting it significantly lower than before and combining it with woody fragrances was first obtained by the present inventors conducting experiments with various combinations. It is.

In the present embodiment, the entire cover portion 20 may constitute the light transmission portion only in a part of the force constituting the light transmission portion that emits the sleeping light to the outside. In any case, the light transmitting part may be provided with a scattering part that scatters the sleeping light from the light source 6, so that soft light can be emitted substantially uniformly from the entire scattering part. It becomes possible and can enhance the awakening effect. Here, “scattering” refers to a phenomenon in which awakening light is refracted or reflected at the scattering portion and diffused in various directions. Specific examples of the scattering portion include a configuration including a portion formed of a light translucent material in the light transmission portion, a configuration including an uneven portion provided on one or both of the inner surface side and the outer surface side of the light transmission portion, Examples thereof include a structure containing fine particles dispersed inside a light transmissive resin or glass constituting the light transmissive part, and a structure in which two or more of these are combined may be used. Fine particles include pigments, dyes, and bubbles.

[0035] If the visible light transmittance of the light transmitting part is too high, visible light is hardly reflected inside the apparatus body 2 and is emitted to the outside. On the other hand, if it is too small, the illuminance may decrease, so 40-80% force S is preferable, and 50-70% is more preferable.

[0036] Although one embodiment of the present invention has been described in detail above, specific aspects of the present invention are not limited to the above-described embodiment. For example, in the present embodiment, the heating element 14 is energized to heat the carrier 4 to promote the evaporation of the drug impregnated in the carrier 4, but the heating element 14 is not provided. In addition, it is acceptable to configure the fragrance component of the drug impregnated in the carrier 4 to spontaneously evaporate. [0037] In the present embodiment, a gap is formed between the base 10 made of a light-reflective material and the cover 20 made of a light-transmitting material, and the user is asleep from the bottom of the base 10 downward. By emitting light, it is configured to promote the release from the entire cover part 20 and to ensure the awakening effect by combining the fragrance and the awakening light, but the light source that emits the awakening light 6 The arrangement of the light source 6 is not necessarily limited to that of the present embodiment. For example, the light source 6 may be arranged so as to emit the sleeping light from the side portion of the base body 10 into the gap between the base body 10 and the cover part 20. Furthermore, the cover portion 20 may be configured not to be provided as it is not necessary.

[0038] In the present embodiment, a single light source 6 is arranged. A plurality of light sources 6 may be arranged. Even in this case, it is possible to make the whole light gently by adopting the configuration including the scattering portion as described above.

Further, as another embodiment of the present invention, a configuration shown in FIG. 3 can be exemplified. In FIG. 3, the same components as those in FIGS. 1 and 2 are denoted by the same reference numerals, and detailed description thereof is omitted.

[0040] The drug transpiration apparatus 100 is configured by accommodating a drug container 40 holding a rod-shaped carrier 4 in an apparatus main body 200 including a main body 201 and a cover 202. In the apparatus main body 200, the main body section 201 is made of a light reflecting material, the cover section 202 is made of a light transmitting material, and the cover section 202 constitutes a light transmitting section of the apparatus main body 200. The drug container 40 can be made of glass, for example, and stores a liquid drug L having an aromatic component therein.

[0041] The main body 201 includes a holding unit 201a that holds the upper portion of the carrier 4 and the drug container 40 at predetermined positions, and further includes a heater 201b and a fan 201c. Further, the force bar portion 202 has a transpiration port 22 formed at a position facing the fan 201c, and is fitted to the main body portion 201. A light source 6 and a projecting piece 202a are provided on the inner surface side of the cover part 202, and the projecting piece 202a is engaged with an engaging part formed on the outer side surface of the side wall of the medicine container 40. The medicine container 40 can be inserted between the main body portion 201 and the cover portion 202 from below, and is detachably supported by engagement with the protruding piece 202a.

[0042] The cover part 202 constituting the light transmission part is shaped so as to bend inward as viewed from the light source 6 side. It is configured so that the sleep light of the light source 6 can be easily emitted from the entire cover portion 202.

A design sheet 50 is attached to the outer surface of the cover portion 202. The design sheet 50 is formed by applying a design or a photograph to a sheet made of a light transmissive material such as a light transmissive resin or glass by means of printing or sticking, and is provided on a side edge. By inserting (not shown) into an insertion slit (not shown) of the cover portion 202, the cover portion 202 is held so as to be tightly attached. The design sheet 50 may be attached to the cover portion 202 in a removable manner or may be integrated.

[0044] The calo heat heater 201b, the fan 201c, and the light source 6 are energized by the operation of the switch 17 by attaching the power plug 16 to the wall outlet.

[0045] According to the drug evaporation apparatus 100 having the above configuration, the carrier 4 is accommodated in the apparatus main body 200 in a state where the drug U is immersed in the drug container 40, and the drug to be evaporated is supplied from the drug container 40. Can be sucked up and refilled. Therefore, it is possible to maintain the awakening effect for a long time by combining the release of the awakening light by the light source 6 and the transpiration of the drug.

[0046] Further, since the design sheet 50 is arranged in the light transmitting portion, a desired design or photograph can be lifted by the wake-up light, and the wake-up action can be promoted from the design effect.

[0047] Further, the transmission part in the chemical evaporation apparatus 100 is formed in a part of the apparatus main body 200, and is formed on the opposite side of the power plug 16 with the light source 15 interposed therebetween. When the is attached to a wall outlet, it is possible to reliably emit a wake-up light to a user in sleep posture.

Example

[0048] Hereinafter, the present invention will be described in more detail based on examples. However, the present invention is not limited to the following examples.

[0049] (Example 1)

In order to investigate the difference in the arousal effect for various combinations of the fragrance type and the color of the arousal light, the following experiment was conducted.

[0050] Seven kinds of invitations based on the hue number in the PCCS hue ring using the chemical evaporation apparatus shown in Figs. 1 and 2 of the present application while the subject is seated in a chair installed in the center of the constant temperature and humidity chamber. The subjects were presented with a combination of drowsiness and six fragrances, and the degree of relaxation after 5 minutes was quantified by the self-report.

[0051] The temperature and humidity chamber was maintained at a temperature of 23.5 to 24.2 ° C, a humidity of 43 to 46%, and an ambient illuminance of 0 to 6 lux. In addition, the illuminance of the awakening light was set to 23 lux at a position 5 cm vertically below the P point force in Fig. 2, and the distance from the drug transpiration device to the subject was set in the range of 0.5 to 1. Om. .

[0052] The hypnotic light has hue numbers corresponding to red:! To 3, hue numbers corresponding to orange 4 to 6, hue numbers 7 to 10 corresponding to yellow, hue numbers 11 to 13 corresponding to green, Hue number 14 ~: 15 corresponding to dark green, hue number 16 ~ 19 corresponding to blue, hue number 20 ~ 24 corresponding to purple, a total of 7 types, and fragrance is “Sandalwood” as woody fragrance And “Pine”, “lavender” and “Gerayuum” as herbal flavors, and “Rose” and “Linden” as floral flavors. To identify the hue number of the hypnotic light, paste white paper (Askul Multi-Paper Super Economy (weight: approx. 64g / m ² paper thickness: approx. 90 / m whiteness: approx. 87%)) to point P in Figure 2. From the position opposite to the light source 6 with respect to this white paper, the colors appearing on the white paper were visually evaluated by five panelists.

[0053] The degree of relaxation is rated on a 7-point scale, with 6 points when you are very relaxed, 5 points when you are relaxed, and 4 points when you are relaxed. “3 points” if you couldn't say whether or not, “2 points” if you could n’t relax, “1 points” if you could n’t relax, and “0 points” if you could n’t relax at all. did. The present inventors have confirmed in advance that the degree of relaxation measured in this way has a correlation with the degree of the hypnotic effect.

[0054] Fig. 4 shows the results of this experiment. As is clear from FIG. 4, when the fragrance is a woody fragrance of “Sandalwood” and “Pine”, and the awakening light is yellow light, green light or dark green light (that is, the hue number is 7 to : 15) has a large relaxing effect (sleeping effect) compared to other fragrances and a combination of sedative light, especially a combination of woody fragrance and green light (ie, hue number 11-13) In Fig. 3, a more remarkable lattus effect (sleeping effect) was obtained. From this result, it was found that the same woody fragrances such as Cedarwood, Guaiatucu, Benzoin, Abies, Hiba, Hinoki, Chromoji, etc. However, it is presumed that there is a remarkable hypnotic effect when combined with a hypnotic light having a hue number of 7 to 15:

[Example 2]

In order to investigate how the illuminance of the awakening light has an effect on the arousal effect using the same chemical transpiration apparatus as in Example 1, the combination of the sandalwood fragrance and the aspiration number of 11 to 13 is used. Based on this, the following experiment was conducted.

[0056] The experiment was performed in the bedrooms of five subjects, and the ambient illuminance was 0 to 6 lux. In addition, the distance from the drug evaporating device to the sleeping subject was set in the range of 0.5 to: 1. Om. The illuminance of the hypnotic light is measured at a position 5 cm vertically downward from the point P in Fig. 2. After the subject actually took sleep at different illuminance, the subject was asked to `` OSA sleep for middle-aged and elderly people. Development and Standardization of Survey Form (MA Version) In accordance with Brain and Psychiatric Medicine No. 10 No. 4, 1999, we requested that the “OSA Sleep Survey Form MA Version” be completed immediately after waking up.

[0057] The “OSA Sleep Survey Form MA version” consists of 20 questions, including “Remaining fatigue” and “Concentration”. Each item is selected from four options. From these results, scores can be calculated for each of the five sleep-related factors (wake-up sleepiness, falling asleep and sleep maintenance, dreams, recovery from fatigue, and sleep time). Figure 5 shows the results of calculating the average score of five subjects for each factor for each illuminance.

[0058] In the experiment, the time of meal and bathing is specified, and for food, food containing caffeine such as coffee and tea, food containing catecholamines such as banana and cheese, and food containing alcohol I ordered to refrain. Also, instruct the person not to take a nap or excessive exercise during the day, not to go to bed outside the home, set the bedtime between 22:00 and 00:00, and set the bedtime between 6 and 8 I directed. In this way, the subject's sleepiness did not vary from day to day.

[0059] In FIG. 5, conditions 2 to 6 indicate cases where the illuminance of the sleeping light is 0 lux, 11 norletus, 23 lux, 36 lux, and 45 lux, respectively. Condition 1 is a comparative example for these cases, in which neither the sleeping light nor the fragrance is used. As is clear from Fig. 5, the illuminance of the second factor (sleeping and sleep maintenance), which is highly related to the hypnotic effect, is 11 to 36 lux. A good hypnotic effect is obtained in the range of tuss, especially in the range of 11 to 23 lux. When the illuminance was 11 to 23 lux, the improvement effect was also confirmed for the first factor (wake-up sleepiness) and the fourth factor (fatigue) compared to other illuminance cases.
