[Prior art]
In recent years, energy conservation has become the most important issue for humanity as part of global environmental conservation. For this reason, while airtightness and high thermal insulation of a living space etc. are advanced, the problem of indoor air contamination has been highlighted. On the other hand, as food safety issues increase, such as E. coli O-157, the demand for fresh vegetables and foods has increased, the use of refrigeration and cooling has increased, the need for energy has increased, and Demand for antibacterial and anti-wrinkle is increasing.
Conventionally, in order to keep freshness, shipping containers, storages for commercial vegetables in the market, etc. are usually stored at a temperature lower than the outside air temperature. In general household refrigerators, fresh food is stored in a vegetable room or refrigerated room, and the freshness is maintained at a low temperature in which microorganisms are difficult to propagate.
[0003]
A conventional example of a warehouse refrigerator is disclosed in Japanese Patent Laid-Open No. 57-16768. When storing crops such as vegetables while cooling them in large quantities, not only the temperature is set accurately, but also a structure that cools uniformly using the pressure difference in the warehouse to cool many vegetables evenly is described .
[0004]
On the other hand, in general household refrigerators, fresh products are stored in a vegetable room or a refrigerator room at a low temperature. However, Japanese Patent Application Laid-Open No. 61-228283 is known as a refrigerator technology in which microorganisms and straws are difficult to propagate in order to maintain food safety. ing. This configuration is shown in FIGS. FIG. 15 is a configuration diagram of the refrigerator, 71 is a refrigerator, 72 is a freezing room, 73 is a refrigeration room, 74 is a vegetable storage room, 75 is a cooler that cools the cold air of a fan 76 that circulates cold air in the refrigerator, 77 A specific container 78 for thawing the frozen food provided in the refrigerator is a deodorizing and fouling unit that blows air from the fan and blows it into the specific unit. FIG. 16 is a block diagram of a fender unit, in which 80 is activated carbon formed in a honeycomb shape by a deodorant unit, 81 is an antibacterial extracted from a regular edible plant in a porous material such as a ceramic formed in a porous unit. Impregnated with active phytoncide. 82 is a frame, 83 is a polyethylene sheet curtain provided between the frame and the deodorant unit to maintain the adsorption effect of the deodorant unit.

[0006]
[Problems to be solved by the invention]
Commercial refrigerated warehouses require a large amount of power to refrigerate large spaces, and many household refrigerators consume a large amount of electricity in the home, preventing global warming and carbon dioxide emissions. There is a strong demand for power saving of these devices for reduction. However, since conventional vegetable storage and refrigerators are methods that maintain freshness only by cooling, energy saving other than maintaining temperature by frequent control cannot be realized. Many proposals have been proposed as countermeasures against bad odors, but their effects have not lasted long, and their practical use has been difficult due to their complicated structure and high cost. Furthermore, antibacterial and antifungal effects due to phytoncide have a drawback that the effects do not last long.
In addition, a large space for storing objects is not available, and due to high airtightness and high heat insulation of the living space, it is difficult to suppress the growth of bacteria and microorganisms and the generation of soot by simple ventilation. On the other hand, if air conditioners and air purifiers are installed, there is a problem that power consumption in homes, hospitals, factories, offices, markets, shops, etc. will increase and there will be major problems in preventing global warming and reducing carbon dioxide emissions. .
[0007]
The present invention has been made to solve the above-mentioned problems, and with a simple configuration with low power consumption, a storage for storing fresh food such as a refrigerator and a vegetable storage room, and a book that is prone to generation of straw. It is intended to provide a device that can sterilize and antibacterial the atmosphere in a storage room such as a storage, a basement, and a closet, or store and work while storing, and suppress the generation of wrinkles.
It is also intended to provide a device with very low energy that maintains freshness without cooling. It is also intended to provide a device that is small and can be installed anywhere to sterilize and antibacterial the atmosphere inside the cabinet, and to suppress generation of wrinkles.

DETAILED DESCRIPTION OF THE INVENTION
Embodiment 1 FIG.
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a conceptual diagram of a domestic vegetable storage that is an embodiment of the present invention, and shows a configuration in which vegetables and fresh food are stored for a long time without being cooled. Reference numeral 1 denotes a vegetable storage, 2 a blower with an antibacterial function incorporating a fan 4, 3 a sustained release element carrying an iodine resin, which will be described later, and 5 a food case for vegetables. This storage has no device or equipment configuration for cooling the internal air. The fan 1 is rotated continuously or intermittently, and iodine molecules are released from the sustained release element in response to the wind speed. FIG. 2 is a structural diagram of a blower with an antibacterial function, and a casing 9 is fixed to the wall of the storage 1. Although the fan 4 is driven by the motor 5, the door (not shown) of the storage is closed and the operation is performed at a time interval set by a timer.
[0022]
FIG. 3 is an enlarged view of a fiber having an antibacterial treatment on the surface in a part of the structure of the sustained release element. 10 is an iodine-based resin having a solid particle shape. Next, FIG. 4 is a structural diagram of the sustained release element 3, and 11 is a nonwoven fabric fixed by a plastic element frame 15. A thin film of binder material in which a vinyl acetate emulsion adhesive is sprayed in advance is formed on the surface of a nonwoven fabric 11 having a thickness of 5 mm, which is a porous substrate, and solid particles 1 mm in the form of granular iodine resin are formed through this thin film of binder material. Although it is desirable that the diameter is about 100 microns or more, the surface of the nonwoven fabric, which is a porous substrate, is evenly coated. The porous base material may be a combination of non-woven fabric, foamed urethane foam, fiber yarn, etc., and an aerosol or an aqueous emulsion type adhesive is used as the binder material.
[0023]
The iodine antibacterial material studied in the present invention is a salt of a triiodide ion of an anion exchange resin having a quaternary ammonium ion as a functional group. This is produced through the process of exchanging chloride ions and triiodide ions of anion exchange resin in the form of chloride by contacting and impregnating iodine with the anion exchange resin under special conditions. In the case of a pellet that is chemically bonded to a quaternary ammonium group that is a functional group and is supported by a crosslinked structure of the resin, commercially available iodine ions are hardly released. This iodine-based antibacterial material is a resin having nitrogen positive ions, and triiodide ions are ion-bonded to these positive ions, so that iodine is not easily separated.
[0024]
However, this iodine-based antibacterial material resin hardly releases at a diameter of 5 mm or more, but the particles become small, and when the surface area ratio exceeds a certain volume, it gradually releases from this surface. . As the diameter of the granule decreases, the ratio of the surface area to the volume increases remarkably, and the release amount increases and the life becomes too short. Iodine is stabilized as iodide ion in the resin, but the condition for releasing the active iodine molecule from the resin by the polyvalent iodide ion becomes heavier as the valence increases, so in the case of pentavalent or heptavalent, a large pellet However, it will be released gradually. In addition, this sustained release amount increases as the amount of air flowing through the iodine antibacterial material, that is, the wind speed applied to the surface increases. The resin that forms the particles may be a resin that allows iodine molecules to pass therethrough. For example, a vinyl acetate resin may be used.
[0025]
However the anywhere difficult to use can not be installed structure to prevent the flow of air in a large pellet large as hydride ion valence. Further, since there is a problem that it is sustainedly released quickly and is not practical for the life of replacement, the present invention employs trivalent iodide ions with a low sustained release and uses small particles so that it can be easily released with a large surface area compared to the volume. The body was fixed to the base material with a binder. As a result, it can be arranged in various forms in the ventilation area, and a large amount of airflow can be received by a short distance of the whole, or a small amount of airflow can be received by a long distribution, and the structure and arrangement according to the application is possible. . Moreover, it can be released gradually with the airflow of the fan considering the life.
[0026]
Next, the operation that characterizes the present invention will be described. The vegetable storage 1 shown in FIG. 1 has an antibacterial function blower 2 integrally provided with a sustained release element 3 in which an iodine resin having an antibacterial action or an antifungal action is fixed to a porous base material with a binder of about 5 mm in thickness. It is provided. In this way, using a sustained-release element carrying a functional material that gradually releases iodine on a porous substrate, and blowing air to this element, the iodine molecules released from the resin are diffused throughout the vegetable storage by the circulating air flow. Supplied to keep the interior clean by preventing the growth of microorganisms floating in the air. As a result, the freshness of the vegetables can be maintained for a long period of time by suppressing corrosion or the like without lowering the temperature, and it is possible to suppress bad odors from fresh products due to the propagation of microorganisms. In addition, it is possible to sterilize bacteria attached to fresh food.
[0027]
In general, the chemical reaction power of iodine is considerably weaker than that of chlorine, but the bactericidal power is strong and has an effective and immediate bactericidal action against bacteria, viruses, molds and the like. Iodized antibacterial resins have been used for water purification, such as used in drinking water purifiers.
In the present invention, iodine molecules, which are antibacterial active molecules released by use in a storage, move to every corner of the storage without adsorbing to or reacting with dust, and are exchanged with bacteria to disinfect the iodine molecules. To keep the inside clean. By rotating the fan at a low rotational speed so that the flow rate of the gas flowing through the release element becomes a flow rate at which iodine is gradually released, the sustained release amount can be suppressed and the life of the release element can be extended.
In addition, after the door of the storage is opened, the fan is operated, the closed state is detected, and the motor is intermittently rotated to circulate the air, so that the slow release is very small in the absence of wind flow. Therefore, the sustained release life from the particles can be further extended. When the door is opened, the rotation of the fan is stopped so that the germs floating outside are not sucked.
[0028]
FIG. 5 shows the structure of the release element 3 in which a nonwoven fabric is woven on a pleat as in FIG. As a result, the area of the nonwoven fabric is increased as compared with the flat plate as shown in FIG. 4, the wind pressure passing through the nonwoven fabric is reduced, the sustained release amount can be further reduced, and the life can be extended. Of course, this sustained release element may be provided in a lattice shape and in parallel with the wind flow. The blower with antibacterial function shown in FIG. 1 shows a structure in which the blower with an antibacterial function is integrally attached to the wall surface of the storage. But you can. In other words, it is possible to preserve the perishables in the storage for a long time just by placing them in a kitchen cabinet or door cabinet or storage. Further, the vegetable case of FIG. 1 is preferably a net-like shelf where the surface of the food is exposed as much as possible and iodine molecules can contact. As a result, there is no room for germs and pupae to grow on the contact surface with the shelf.
[0029]
As described above, in the present invention, a device for lowering the temperature, for example, a compressor that pressurizes and expands the refrigerant by a compressor and obtains a low temperature, such as a refrigeration cycle used in a refrigerator, and a fan that cools the compressor are provided. There is no need to install a heat exchanger or the like, and there is no need for a structure that keeps the temperature low, and there is no need to use a refrigerant that affects the global environment. In addition, since the control is simple by simply rotating the fan at a low speed, it is possible to significantly reduce energy. As a result, it is possible to store fresh products such as vegetables without rotting them without using a small device for household use, or to keep a large commercial device safe. It also frees you from the hassle of handling fresh food and cooking while worrying about bacteria. It is more effective if the operation is stopped when the door is opened in conjunction with the opening and closing of the door. In the case of a cold car, a device for lowering the temperature is required and the weight of the load to be transported is limited. However, the structure of the present invention does not require such a limitation.
[0030]
FIG. 6 is a characteristic diagram relating to the wind speed dependence of the iodine sustained release amount of the sustained release element. This characteristic diagram shows a structure in which the sustained release element 3 is provided on the suction side of the fan 4 shown in FIG. 2, and the weight of iodine released from the sustained release element having a sustained release surface of 30 centimeter square is the wind speed 0.2-1. The results of measurement in the range of 0.0 m / s are shown. The sustained release amount is small when the wind speed is 0.5 m / s or less, but the sustained release amount increases rapidly when it exceeds 0.5 m / s. That is, when the inside of a narrow warehouse or a fan is operated continuously, an effective wind speed may be given to the sustained release element at 0.5 m / s or less. On the other hand, when operated at a wind speed of 0.8 m / s in a closed room equivalent to 6 tatami mats, the concentration of iodine contained in the indoor air was about 0.05 ppm, and a high fungicidal effect was obtained. When the bread was left in the room at a humidity of 85% or more, it was found that there was no problem even after 2 weeks or more by sustained release with the sustained release element, against the situation where the mold covered the entire surface of the bread in 6 days. That is, even in a wide room, such a wind speed is sufficient, and it can be said that it is important for the life of the sustained release element not to set the wind speed to about 1 m / s or more.
[0031]
Embodiment 2. FIG.
In the first embodiment, a configuration in which the product is stored without lowering the temperature without having a cooling function is shown. However, it can be used in combination with a configuration in which food is cooled with cold air like a refrigerator. FIG. 7 is an explanatory view of the inside of the refrigerator viewed from the door side. 17 is a cold air suction air passage for sucking the air in the refrigerator into a cooling heat exchanger provided on the rear surface of the refrigerator, and 18 is a side example which is an air passage of the side cold air outlet 23 for blowing out the cooled air from the side surface into the refrigerator. The air duct, 19 is a side damper that adjusts the amount of cold air blown out to the side, 21 is a refrigerator body, 24 is a ceiling duct that is the air passage to the ceiling cold air outlet 25, 26 is a refrigerator compartment, and 28 is a cold air passage for the back. . Reference numeral 31 denotes a heat insulating partition wall that partitions the freezer compartment and the refrigerator compartment.
[0032]
FIG. 8 is an explanatory view showing a part of the refrigerator in cross section. 27 is a door pocket provided on the door 22 of the refrigerator, 34 is a heat insulating material for maintaining the temperature in the cabinet constituted by the door 22, the refrigerator main body 21 and the partition wall 31, 36 is a shelf on which food is placed, and 35 is from the back side. A blowout port 40 for blowing out cool air is a recess for accommodating the release element 3. FIG. 9 is a conceptual diagram showing a door pocket inside the door, and reference numeral 47 denotes an object to be cooled which is food arranged in the door pocket 27. ,
The refrigerator is provided with a fan for circulating cold air, and air is circulated by the fan. A part of the circulating air can be used to diffuse iodine molecules from the release element into the refrigerator. In general, there are air outlets for blowing out cool air on the ceiling, side and back of the cabinet, and there are air inlets for sucking in cold air on the bottom surface, and these five surfaces have a relatively large air volume.
[0033]
On the other hand, cold air circulates on the remaining door surface, but there is a pocket here, which obstructs the circulation of the cold air, and a cooling object 47 to be cooled is placed in this pocket. A large amount of airflow does not flow behind the door. That is, the flow of cool air is hindered by the store. In this way, the wall behind the pocket and just below the upper pocket as shown in FIG. 7 and FIG. 8 is the place where the wind is most difficult to rotate in the cabinet. Therefore, it is effective for antibacterial and antifungal measures because cold air diffuses and circulates in the cabinet.
[0034]
In other words, a base material fixed with antibacterial resin particles that release iodine is directly attached to the door pocket of the refrigerator or stored in a recess provided in the door inner plate, and iodine is released into the refrigerator by the air flow in the refrigerator. It enhances the sterilization effect in the storage and maintains the freshness of fresh food for a long time. In the case of a refrigerator for home use, the rotation speed of the fan is high to circulate cold air throughout the interior of the refrigerator, but the portion close to the door of the door pocket is the place where the cold air that cools the stored item indirectly circulates, and the release amount is Less. In general, the fan is rotated when the internal temperature rises. In some cases, after defrosting the heat exchanger, there is a case where only the fan is turned to improve the startability, but it is a short time. Also, do not rotate when the refrigerator door is open. As described above, since the extended release life is extended and the closed space is circulated, effective release can be performed without wasting the released iodine molecules. The place where the sustained release element is installed is not limited to the door pocket, but may be any place where the flow velocity of the cold air is low and the wind speed is low. For example, it may be provided near the cooler for cooling the cold air.
[0035]
FIG. 10 shows another example of the structure of the sustained release element. Reference numeral 13 denotes a contact prevention plate. When attached to the door pocket, there is a risk that the antibacterial resin particles fixed on the surface of the base material of the sustained release element may come off or be rubbed by the stored items. On the other hand, the air is circulated, but contact prevention may be performed so that food does not hit it. It is not limited to the one shown in the figure, and the storage side may be closed and the air may be passed between the inner wall of the door.
FIG. 11 shows another structure of the sustained release element, wherein 6 is a slit provided in the upper part and the lower part, and 14 is a closing plate for closing other than the slit of the sustained release element. A base material having antibacterial resin granules fixed on the surface is housed in a box, and thin ventilation slits are provided at the upper and lower ends. With such a configuration, only a very small portion of the circulated cold air passes through the release element regardless of where it is installed in the storage. That is, by selecting the width necessary for the amount of air flowing through the slit, adjustment means for adjusting the flow rate of the gas that is disposed in the vicinity of the release element and flows through the sustained release element is provided. However, in the structure shown in the figure, the closing plate 14 can be removed to replace the sustained release element. Further, when the life of the antibacterial resin particles is lost due to sustained release, the color tone of the surface changes. Thus, the sustained release element can see if it needs to be replaced by looking at this surface. On the other hand, if the sustained release element is completely closed, the surface cannot be inspected. The closing plate of FIG. 11 can be moved up and down by a handle 91 and the internal elements can be checked. The iodine ion exchange resin on the pellet is black. When it is close to powder, it becomes brown, and when iodine is removed, it changes to beige. When the surface is closed, the surface may be covered with a transparent or visible plastic film or sheet that does not allow iodine to pass therethrough. Needless to say, the surface inspection for confirming the life of the sustained-release element is easiest when the sustained-release element is provided on the door.
[0036]
Embodiment 3 FIG.
FIG. 12 shows an example in which the present invention is applied to a refrigerated warehouse for storing vegetables. 41 is a cooler that cools the air blown by the cooling fan 42, 43 is a circulation fan that generates a differential pressure and circulates through the block on which the vegetables 7 placed on the pallet 50 are stacked, and 44 An ice heat storage tank 49, which is a cold heat source for supplying cold heat to the cooler 41 by means of a pipe opening / closing means 45 and a adjusting means 46 for adjusting a heat medium such as a refrigerant, and 49 is a wind guide plate for circulating the cooled air in the storage 48 It is. FIG. 13 shows a structure of a sustained release element that is arranged adjacent to the circulation fan 43 in the vegetable warehouse 48 and releases iodine gradually, and antibacterial resin granules are fixed on the surface of the honeycomb-like cardboard 53. As another example, a blower 58 with an antibacterial function is provided on the floor of the vegetable warehouse 48 in FIG.
[0037]
In FIG. 12, in the storage 48 which is a vegetable warehouse, the cooler 41 and the blower 42 can keep the temperature in the storage at a low temperature suitable for stored items. Moreover, freshness can be maintained through the air cooled uniformly with respect to the whole vegetables piled up by the air blower 43 for circulation. On the other hand, the slow element 3 having an antibacterial resin fixed on its surface releases iodine molecules, and this iodine is diffused through the circulation of air throughout the vegetable warehouse to keep the freshness of the vegetable. Maintaining freshness is vital for business use, whereas for cooling, a heat transfer medium can be supplied by both another heat source (not shown) provided on the heat source machine side and ice heat storage. In any case, that is, even if one of them suddenly stops, the other supplies refrigerant to the cooler so that cold air can be supplied. Further, the sustained release element can be released into the circulated air without reducing the differential pressure due to the honeycomb structure.
[0038]
If the sustained release amount is small or if a backup system is required, a blower 58 with an antibacterial function incorporating a portable type sustained release element may be installed on the floor and operated. Alternatively, only the blower 58 with an antibacterial function may be provided without providing the sustained release element 3. As a result, the cooling fan 42, the circulation fan 43, and the sustained release fan device 58 can be operated independently. It is possible to stop the circulation of the refrigerant from the cooling fan or the cold heat source according to the kind of fresh food to be stored or other stored items, or according to the temperature in the warehouse. As a result, power consumption can be greatly reduced. Further, when working inside the storage room or taking in and out stored goods, the sustained release fan device 58 may be stopped. Iodine is indispensable to the human body, and the amount released is small and there is no problem at all. However, if there is a specific smell and it is unpleasant, only this fan should be stopped.
[0039]
This storage has a fan that circulates gas to the sustained release element that releases iodine, a fan that circulates gas to the storage, and a device that cools the air separately. Use is possible, and energy can be greatly reduced. However, in this storage, iodine ions that are released slowly by operating a fan that circulates gas through the sustained release element that releases iodine slowly and a fan that circulates gas through the storage at least simultaneously for a predetermined time, to every corner of the storage, Alternatively, it is necessary to spread and spread enough to the stored fresh food.
[0040]
In the vegetable refrigerated warehouse of FIG. 12 and the household refrigerator of FIG. 7, an electronic control circuit is provided for driving a compressor, a pump, and the like that circulate the refrigerant. This circuit includes a transformer that produces direct current from an AC commercial power supply, a control power rectifier circuit, a temperature controller in the cabinet, a microcontroller that creates control signals to drive the compressor, switches, transistor inverters, gate amplifiers, fan drive inverters, etc. In these inverters, a circuit is constituted by a MOS FET and a freewheeling diode. Comparing the temperature of the temperature sensor provided in the chamber with the temperature set in the temperature adjustment circuit, if the temperature in the chamber is higher than the setting, the microcontroller issues a command to rotate the compressor frequency higher . If the set temperature is high, stop the compressor. The motor for the fan that circulates the air in the refrigerator is also operated in accordance with a command from the microcontroller almost in synchronization with the operation of the compressor. Similarly, a command for operating the fan motor is issued from the microcontroller in conjunction with the opening and closing of the door. When each fan is provided independently, each fan can be freely operated by setting the operation time of each fan in advance by a timer provided in the microcontroller.
[0041]
Embodiment 4 FIG.
FIG. 14 is a structural diagram showing another example of the blower with an antibacterial function of the present invention, in which 59 is a water tank filled with water, 3 is a sustained release in which water is dropped from the water tank 59 while carrying an iodine resin. An element, 64 is a drain pan that collects water that has wetted the sustained release element 3 so that it can be drained to the outside of the machine, 63 is a blower that rotates the fan 4 by a motor and sucks air from the intake port 61 and discharges it to the exhaust port 62, 58 It is an air purifier. The surface of the iodine-based resin 10 of the sustained release element can be removed by removing the inside from the air inlet 61.
[0042]
As shown in FIG. 14, a water tank is provided on the sustained release element 3, and water is supplied from the water tank 59 to the sustained release element so that the sustained release element is wet. Let the wind pass through. In this structure, iodine is less likely to be released from the sustained release element than when the sustained release element is dry, so the air purifier is an air purifier that cleans the air outside the machine. That is, the air in the vegetable storage room or refrigerator, which is a library or storage, is taken into the air purifier by the operation of the blower, and is brought into contact with the wet controlled release element for sterilization. It is not a method of sterilizing and antibacterial storage in the warehouse by releasing iodine molecules mainly in the air and diffusing it in the room or in the warehouse as described so far. It can be used in the base material or in places and times where conditions such as disinfection and antibacterial through water are not desired to be released to the outside using the iodine molecules present in the water. Yes, you can use it as an air purifier anytime, anywhere, without worrying about anything.
[0043]
Since the sustained release element having a functional material that gradually releases iodine supported on a base material is wetted with water and air is circulated to make contact with the sustained release element, a commercially available product is used as the pellet size. It may be used as it is.
As a water supply device that supplies water to the sustained release element, a structure is shown in which a water tank is provided above the release element and water is dripped from a water supply port opened at the bottom of the water tank. But you can. Bacteria and spore spores floating in the air can be sterilized by taking them into water and attracting them to the iodine resin by iodine ions released into the water. By providing a dust removing filter at the air supply port with the structure of the present invention, the water can be kept clean by iodine, so that it is only necessary to circulate the water. However, if a window is provided on the side surface of the casing 9 accommodating the fan of the air cleaner 58 and the sustained release element, the surface of the iodine-based resin can be seen. The window may be covered with an open / close lid or a transparent window material. It may also be used as a lid that can replenish the water evaporation.
[0044]
When antibacterial performance by E. coli was evaluated with an ATP analyzer by immersing a non-woven fabric that had been antibacterial processed into 100 cc water using the remaining hot water of a bath contaminated with microorganisms, The number of bacteria could be reduced. In addition, an extremely high effect is obtained even in the antifungal test using blue mold.
[0045]
The present invention provides an air purifier that carries an antibacterial or antibacterial iodine-based antibacterial material on a base material and releases iodine from the sustained release element into the air or wets it with water for sterilization or fouling. I can. As a result, the freshness of refrigerators and vegetable storage rooms can be kept fresh without lowering the temperature as much as possible, and antibacterial and antifungal measures against food safety due to E. coli O-157, etc. Can be sterilized and protected. Iodine is commercially available as a resin on pellets that are ion-bonded to an anion exchange resin as negative ions of iodine. When iodine is gradually released into the air by vaporization from the vicinity of the surface, iodine resin is produced as a solid. Since it is related to the size of the particles and the wind speed corresponding to this, it is small so that the slow release is performed, and it is set to an appropriate wind speed, but if it is too small, or the wind is too strong, the release amount is not gradually released. Since it becomes too large and the sustained release element must be replaced immediately, it is necessary to select a convenient particle size and wind speed. The dependence of the sustained release amount on the wind speed increases as the wind speed increases rather than linear as shown in FIG.
[0046]
Examples of volatile antibacterial and antifungal active molecules that are harmless to the human body include hinokitiol, wasaolo, naphthalene, bay oil, cinnamon leaf foil, clove bud oil, and origanum oil. Iodine has the most antibacterial and antifungal effects. ing. By releasing such volatile active molecules into the air from the sustained release element, the growth of airborne microorganisms can be prevented, the air pollution caused by microorganisms can be reduced, and malodors can be eliminated. Long-term storage is possible by sterilization and the like, and energy for cooling storages and refrigerators for storage can be greatly reduced.
