Description

  The present invention relates to an animal and plant breeding facility, an animal and plant bred using the plant, an activated gas generator, a method for producing an animal and plant, and an animal and plant bred by the method.

  Animal and plant breeding facilities are used in various fields. Specifically, in the case of animals, there are zoos, insect houses, botanical gardens, poultry farms, pig farms, cowsheds, milking farms, ranches, aquariums, pet shops, farms and the like. The facilities used in these places are formed by surrounding the four sides with a metal structure consisting of rods, meshes, or plates, and keep animals in their internal space (bred room). is there.

  In the case of plants, examples include farms, mushroom farms, and the like, and examples of facilities used in these places include greenhouses using resins such as plastic houses.

  What is important in these animal and plant breeding facilities is hygiene management. The hygiene management needs to be considered from three main points of view. This is shown below.

  (1) The first viewpoint needs to consider the influence on animals and plants themselves. If hygiene management is inadequate, animals and plants may be infected with viruses, molds, airborne bacteria, and allergen components that float in the space inside the breeding room. For example, when considering breeding facilities in poultry farms and pig farms, if chickens and pigs in the breeding room are all infected with a virus or the like and die, the cost damage will be enormous. Moreover, the infected animal loses its significance as an economic animal, and for example, it is necessary to incinerate all the chickens and pigs in the chicken farm or pig farm, resulting in a large cost loss. In addition, in animal and plant breeding facilities for viewing at zoos, aquariums, botanical gardens, etc., if rare animals and plants of special varieties are bred, they are infected by viruses, molds, airborne fungi, and allergen components that float in the space. There are cases where there is no symptomatic treatment in case of failure and proper treatment cannot be performed.

  (2) The second viewpoint needs to consider the impact on human beings involved in animal and plant breeding facilities. Viruses, mold fungi, airborne fungi, and allergen components floating in the facility space are human beings who are engaged in the operation of raising flora and fauna in the facility, or who are watching the flora and fauna in the breeding facility for viewing animals and plants There is a possibility of being infected. In addition, there is a problem that humans are extremely uncomfortable due to body odors from animals and plants and stool odors. It is also possible that the air in the interior space where animals and plants exist leaks into the exterior space and drifts as odor.

  (3) The third viewpoint needs to consider the impact on the local environment where the breeding facility is installed. When air in the internal space of animal and plant breeding facilities is released to the external space, odors that people in the area may feel uncomfortable may be released. In addition, viruses, molds, airborne bacteria, and allergen components may be released due to animals and plants. May affect unrelated environment around the facility.

  As described above, as described in (1) to (3), it is understood that hygiene management is extremely important in animal and plant breeding facilities. Of course, in these animal and plant rearing facilities, hygiene measures have been sufficiently taken, but it is still not complete, and cases of infection due to infection from animals and plants have been reported. .

  Therefore, in order to solve the above problems (1) to (3), as measures currently taken in terms of hygiene of animal and plant breeding facilities, there are the following methods.

  (A) A method of cleaning the inside of the breeding facility can be mentioned. Frequently cleans filth such as animal and plant manure in the interior space of the facility. Or the method of washing the equipment in a facility frequently is mentioned.

  (B) A method of frequently exchanging the equipment in the breeding facility can be mentioned. For example, there is a method of frequently exchanging feed and drinking water given to animals and plants in the facility.

  (C) A method of improving the sanitary condition of animals and plants in the breeding facility can be considered. For example, it is a method of removing dirt adhering to the skin, feathers and scales of animals and plants by washing the body surfaces of the animals and plants present in the internal space of the production / breeding facility.

  (D) A method of purifying the air in the breeding facility can be considered. For example, by circulating the air in the facility using a filter using activated carbon, etc. used in known air purifiers, the activated carbon adsorbs viruses, molds, airborne bacteria, allergen components, and odor components. And try to remove it.

  These methods are used to manage the hygiene of breeding facilities. However, these hygiene measures described in (a) to (d) are all rather than suppressing the increase of viruses, molds and airborne bacteria that increase with time. There was a strong meaning of removing increased viruses, molds, airborne bacteria, and allergen components. In addition, the odor generated by animals and plants is simply a matter of removing the drifting in the production / breeding space in order, which can be said to be a passive method. Therefore, even if these methods are implemented once, the virus, mold fungus, airborne bacteria, allergen components and odor increase immediately, so if a certain period of time passes, the same work must be repeated routinely. There was a problem of not becoming. Such routinely repetitive operations require a great deal of labor and lead to an increase in costs for animal breeding and production.

  Of course, as a method for suppressing an increase in cost, various methods (A) to (D) described above may be automated by using dedicated equipment and devices. However, taking into account the reliability of the equipment itself, sudden accidents, etc., it may be difficult to fully automate by the machine, and it is also necessary to periodically perform maintenance (maintenance) by humans. At that time, there is a possibility that the person in charge of the work may be affected by infection with viruses, molds, airborne bacteria, and allergen components.

  Furthermore, in a conventional breeding facility having passive sanitary facilities as described above, a clean state is maintained by a technique that uses a filter to clean the air. However, this method requires periodic replacement and cleaning of the filter.

  Therefore, as a method for solving these problems, a method of releasing a gas (an activated gas) containing any effective component is used instead of using a passive filter or a cleaning method as in the past. Yes. This is a method of obtaining an effect by releasing a gas containing an active ingredient into a production / breeding facility. The activated gas described here is characterized by using ozone or an ion-containing gas as a gas component. A conventional example will be described below.

(1) When the activation gas contains ozone (when ozone has the most effect)
For example, in Patent Document 1 (Japanese Patent Laid-Open No. 10-113097) and Patent Document 2 (Japanese Patent Laid-Open No. 10-113096), as an insect breeding device and an insect breeding method, A method of providing an ozone generator and a sterilizer in the apparatus is disclosed. By using this method, the breeding device is not contaminated with viruses.

  Ozone has long been known to have a bactericidal and deodorizing effect. As a method for generating ozone, a method using a discharge phenomenon, a method using ultraviolet irradiation, and the like are known. For example, Patent Document 3 (Japanese Patent Laid-Open No. 9-243102) describes an invention of a ceiling-embedded air conditioner. According to this document, it is described that odors in indoor air are removed and decomposed by the strong oxidizing power of ozone.

  However, when a gas containing ozone is used as the activation gas, the harmfulness of ozone itself must be taken into consideration. In other words, ozone is effective in sterilizing / inactivating viruses, molds, airborne bacteria, and allergen components, and deodorizing odor components if ozone is very small. Become. When the ozone concentration is high, irritation to the respiratory system, eyes, mucous membranes, etc. is great, which may adversely affect the human body. The allowable ozone concentration varies depending on the laws and regulations of each country. For example, in Japan, the value of photochemical dioxin (generic name for ozone and other oxidizing substances) is 0 per hour as an environmental standard for air pollution. .06 ppm or less. Appropriate management of ozone concentration is required. In addition, ozone has a peculiar pungent odor and feels uncomfortable.

(2) When the activation gas contains ions (when ions have the most effect)
In recent years, methods of using ions to inactivate viruses, mold bacteria, airborne bacteria, and allergen components in the space, or deodorizing odor components are attracting considerable attention in recent years. Conventionally, there have been reports as follows regarding a method of purification using ions in the air. The following describes the effects of ions in the air on animals and plants.

(A) Growth action on animals (mammals) (A-1) Non-patent document 1 (Tchijevsky's “Air ionization in the national economy” (1960)) reported that pigs, rabbits, and mice were affected by air ions. He expressed his view that it significantly increases physical activity such as sheep, reproductive function, appetite, and weight. In the case of pigs, it is stated that treatment with negative ions significantly accelerated recovery from the disease (bronchitis and pregnancy toxemia). It has also been reported that wool obtained from male sheep treated with negative ions was longer, stronger and thinner than when not treated with negative ions. In addition, when female cows were bred in negative air ions for 47 days, there was a marked increase in milk production, protein and fat content in milk, and body weight (average body weight increased by 20 kg per head) It is reported that sexual activity (reproductive function) and blood catalase levels were also significantly increased by negative ions.

(A - 2) According to the report of the effect Mozzherin and its researchers for the pig (1974), 300,000～400,000 pieces in piglets / cm ³ of between one month a light negative ions, twice daily, 1 Irradiation for 30 minutes per cycle increased pig body weight gain by 7-19%, oxygen uptake by 4%, carbon dioxide uptake by 2%, lung ventilation by 16%, breathing depth Reported a 13% increase in protein digestibility, a 8.9% increase in fat digestion, a 8.4% increase in fat digestibility, and a 13% increase in fibrin digestibility.

(I) Growth action on small animals (insects) (I-1) Effect on silkworms According to a joint study by Krueger and Kotaka (1966), polar ions in the air are charged with the polar ions in the air. It has been reported to significantly increase the growth rate and biosynthesis of catalase, peroxidase and cytochrome c oxidase in body fluids. He also reported that the development of the silk layer was significantly increased by promoting the growth of larvae and leading to faster onset of threading.

(B-2) Effect on bees According to Tchijevsky (1960), regarding the application of air ions to the beekeeping industry, it is reported that bee mortality is reduced by an appropriate amount of negative ions, and flying activity is increased. The increase in the flying activity of the bees coincides with the time when the natural ion power is maximized in one day. It has been reported that the flying activity of the bees increases with increasing sunlight dose and air dryness, that is, with increasing basic weather factors that promote ionization of atmospheric air.

(C) Growth effects on plants (c-1) Effects on crops (Reports from Suganuma and Nakayama, Japan)
According to a report by Kakinuma and Nakayama in Japan (1982), when exposed to an electric field of 10 to 20 kV / m, an increase in yield was observed in sweet potatoes and radish.

(U-2) Krueger's report (1959 and 1962)
It was reported that when oat seeds were exposed to 10,000 ions / cm ³ ions, the elongation increased by 60%, the body weight increased by 25-30%, and the components increased in protein, nitrogen content and sugar content. ing. After that, he conducted experiments to see the effects of ions on plants with barley, lettuce, peas, and so on. As a result, it is reported that the growth of barley seedlings is suppressed in an ion-free environment.

(U-3) Report of Yamaguchi and Krueger (1983)
In tomato hydroponics, exposure to negative ions of 6,000 to 20,000 / cm ³ (during seedlings during the day and then only during the day) shortens the period from sowing to harvesting by about 2 weeks. It is reported that the results of ion exposure were good, with the yield per week being 50% in the first 3 weeks and the cumulative yield being 27% in the 6th week. Furthermore, as a whole, it is reported that there is a lot of minerals and the taste is good, suggesting that there is a possibility of practical use.

  Furthermore, Shigemitsu (1999) summarizes the results of Krueger's experiment as follows.

For oats, there is no effect on germination, but the dry weight increased in the ion-treated section, and the growth was large in the negative ion-treated section, and it was reported that the effect of ions was observed as a whole. Barley (larvae) was exposed to positive ions 11,000 / cm ³ and negative ions 9,000 / cm ³ for 15 days to investigate resistance to true brown spot injury, plant height, live weight and dry weight. Then, it was reported that positive ions delayed the onset of disease for 3 days, negative ions had no onset, and a tendency to slightly increase plant height and dry weight was observed.

  As described above, as described in (1) and (2), the method using ions in the air is effective for breeding, producing and managing animals (mammals), insects and plants. It has been reported to affect.

Japanese Patent Laid-Open No. 10-113096 (see paragraphs 0006 to 0008) JP-A-10-113097 (see paragraphs 0006 to 0009) JP-A-9-243102 (see paragraph 0006) “Air ionization in the national economy” by Tchijevsky (1960))

  However, in the above (1) and (2), although the effect of ions in the air on animals and plants is described, specific ion species and the like are not specified. In addition, the reason why these effects appear and the cause investigation are insufficient, and the possibility of low data credibility cannot be denied.

  For example, in the report described in Non-Patent Document 1 of (A-1) above, the definition of air ions is ambiguous and precise measurement is not performed. Furthermore, the air ion concentration is unknown, and the measurement method of ions and the definition of mobility are not clearly specified.

  Also, in the report of Mozzherin et al. In (A-2) above, the principle and reason for why such an effect is obtained is not clearly described, and whether ions actually exert a remarkable action. It is reasonable to think that it is impossible to judge.

  Therefore, a method for clarifying the effect of air ions on animals and plants has not been established so far, and conventional animal and plant breeding facilities leave room for improvement in hygiene management.

  In view of the above problems, the present invention provides an animal and plant breeding facility capable of further improving hygiene management, an animal and plant bred using the same, a method for producing the animal and plant, and an animal and plant bred by the method. It is an object.

  In order to achieve the above object, the present invention is not a passive method as in the prior art, but actively removes / inhibits viruses, molds, planktonic bacteria, allergen components, and odor components that increase every time before growth. It has come to discover that it can be activated. If the growth can be actively suppressed, the breeding feed can be exchanged and the degree of washing of the breeding facility can be lowered, leading to cost reduction, raising breeding efficiency, and improving the safety of humans and animals and plants. That's it.

  That is, the present invention is an animal and plant breeding facility provided with an activated gas generator for releasing activated gas for sterilizing airborne bacteria in the breeding room. The breeding facility is a facility for breeding, producing, and growing animals such as animals and plants. The material constituting the breeding facility is not particularly limited. For example, a metal material, a resin material such as wood, plastic, glass, ceramic, paper material, stone material, cement material, carbon fiber material, or the like is preferably used. Can do. When animals and plants to be bred require a water space such as fish, amphibians and reptiles, it is preferable to have a sealed structure so that water in the breeding room does not leak outside. When animals and plants to be bred can fly in the sky like birds and insects, it is preferable not only to surround the sides but also to provide a roof or the like to block the upper surface.

  The activated gas generator may be provided at any position inside or outside the breeding room as long as the activated gas can be released into the breeding room, or at a position away from the breeding room. In addition, it is desirable to provide an air blowing means so that the activated gas can sufficiently reach the interior space of the breeding room so as to diffuse the air containing the activated gas component into the space. The form of the air blowing means is not particularly defined, but includes, for example, a method of diffusing into the space using blades such as those used in electric fans, or containing the activated gas component by reducing the pressure inside the space. A method of introducing a new gas into the space can be given. The activated gas generator is not limited, but generates activated gas by a discharge method or a light irradiation method.

  Specifically, the activated gas generation device has a plurality of air blowing units including air blowing paths and air blowing means, and the air blowing directions of some of the air blowing units and the air blowing directions of the other air blowing units are opposite to each other. It can be set as this, and it can be set as the aspect which provides an activated gas generation | occurrence | production means in the at least 1 ventilation part among some ventilation parts.

  As a ventilation path, pipes, such as a duct which induces air, are illustrated, and what is necessary is just to arrange one end in the space side where activated gas is discharged, and the other end in the other space side. As the blowing means, a fan is exemplified, and it may be provided in the blowing path. Air can be exchanged between the space on the one end side and the space on the other end side of the duct by such a blowing section including the blowing path and the blowing means.

  In addition, a plurality of air blowing units are provided, and the air blowing directions of some of the air blowing units and the air blowing directions of the other air blowing units are set to be opposite to each other. The reverse direction means the relationship between the direction toward the space where the activated gas is released and the direction toward the other space.

  The blowing direction of some of the blowing units is a direction that flows toward the space where the activated gas is released, and at least one of the blowing units is provided with an activated gas generating means. The activated gas can be diffused into the space by the blowing means. In addition, as long as the ventilation part provided with the activated gas generation | occurrence | production means is connected to the activated gas discharge | release space side, the other end is good also as a form sealed without making it communicate with another space. Moreover, the number will not be specifically limited if the number of ventilation parts is two or more.

  It is preferable that the plurality of air blowing units in which the air blowing directions are set in the reverse direction and the activated gas generating means are configured as a unit. The function of generating the activated gas, blowing the activated gas (diffusion), and replacing the air can be realized only by providing the activated gas generator. Therefore, since it is not necessary to provide a separate air blowing part etc., construction becomes easy.

  Furthermore, it is preferable to provide a control unit that increases or decreases the amount of air blown by each of the air blowing units of a part of the air blowing units and another air blowing unit that reverses the air blowing direction based on a sensor or an instruction. In the case where a plurality of air blowing units are provided integrally, a single control unit can be linked with the air blowing means of each air blowing unit. It is possible to easily realize a configuration in which the air in the breeding room is not leaked while the sterilization performance is changed in accordance with the change in increase or decrease in the air flow rate.

  For example, by adopting the following configuration, effective sterilization can be achieved at low cost. The configuration includes a sensor that directly or indirectly detects the state of occurrence of viruses, molds, airborne bacteria, allergen components, etc., or the state of animals, and each air blower is controlled by the control unit according to a signal from the sensor. The amount of air blown by the air blowing means is increased or decreased.

  Sensors that detect the occurrence of viruses, fungi, planktonic bacteria, allergen components, etc., or animal conditions are not limited as long as these conditions can be detected directly or indirectly. In addition, a temperature sensor, a humidity sensor, an object sensor, and a biological sensor can be exemplified as those that can be detected indirectly, and they can be provided alone or in combination. These sensors are only required to be disposed at positions where the respective objects can be detected, and may be provided at a location away from the activated gas generator. The state of occurrence of viruses, molds, planktonic bacteria, allergen components, etc. means the degree of activation of viruses, molds, planktonic bacteria, allergen components, etc., or the amount of viruses, molds, planktonic bacteria, allergen components, etc. It is.

  The activated gas release space, such as the virus being activated by these sensors, the concentration of the virus is high, the resistance of the animal in the activated gas release space is reduced, etc. When it is detected that the influence of a virus or the like on the animal present in the state is high, the control unit increases the air flow rate of the air blowing means of the air blowing unit that blows air to the space where the activated gas is released, and In addition, when it is detected that the influence of a virus or the like on the animal is low, control is performed so as to reduce the air flow rate.

  Specifically, an example in which a temperature sensor is used will be described. The activated gas generator is provided with a temperature sensor for detecting the air temperature, and the air blower of the air blower blows air to the space where the activated gas is released by the control unit according to the fluctuation of the air temperature by a signal from the temperature sensor. Increase or decrease the air flow rate.

  As this setting condition, there is an aspect based on the temperature at which the growth of viruses, molds, airborne bacteria, allergen components and the like becomes active, that is, the optimum temperature. When the temperature detected by the temperature sensor is within the optimum temperature range, increase the air flow rate of the air blowing means of the air blowing unit that blows air to the space where the activated gas is released, and before the activated gas reacts and disappears A large amount is sent to the target space. When the air temperature is outside the optimum temperature range, the air flow rate is set to be lowered. The optimum temperature varies depending on the type of microorganism, and can be changed depending on the object to be removed.

  Here, a typical optimum temperature is exemplified. When microorganisms are classified according to the optimum temperature for their growth, they are roughly divided into thermophilic bacteria, mesophilic bacteria and thermophilic bacteria, and the optimum temperatures are 20 degrees or less for thermophilic bacteria, 25 to 40 degrees for mesophilic bacteria, and thermophilic bacteria. It is 45 degrees or more. In addition, since there are many mesophilic bacteria in nature, it is preferable to use the optimal temperature (25-40 degree | times). Moreover, most optimum temperature of mold | fungi which generate | occur | produce in a house or a building is generally 5-35 degree | times.

  Further, as another setting condition different from the mode based on the optimum temperature, there is a mode based on the temperature that causes a decrease in the physical strength of the animal. In the case of human beings, it is said that the optimum temperature at which a person can spend comfortably is 18 to 26 degrees, and it is generally considered that when the temperature is 30 degrees or more or 10 degrees or less, the physical strength is reduced. When physical strength is reduced, it becomes easy to get illness such as influenza, so the temperature is below a certain temperature (for example, 10 degrees or less for humans) or above a certain temperature (for example, 30 degrees or more for humans) In order to improve the sterilization performance, as the mode of increasing the amount of air blown by the air blowing means of the air blowing unit that blows air to the space where the activated gas is released, and blowing a lot of activated air containing the activated gas in the target breeding space Also good. If the temperature is outside the above range, the air flow is reduced. In addition, since the temperature which causes a physical strength fall of an animal changes with the kind of animal and the health state of the animal, it can be changed suitably.

  It should be noted that the amount of air flow in the case of “increasing the air flow rate of the air blowing means” can be sent in a large amount to the activated gas discharge space before the activated gas reacts and disappears. This is the amount of air that can be sterilized to such an extent that viruses and the like do not affect animals and the like present in the space. In addition, the amount of air flow in the case of “decreasing the air amount of the air blowing means” means that the amount of air is less than that in the case of “increasing the air amount of the air blowing means”. This is the amount of air that can be sterilized to such an extent that viruses in the gas release space do not affect animals or the like present in the space.

  In addition to the temperature sensor, a humidity sensor and an object sensor are also considered as sensors that indirectly detect the occurrence of bacteria. When a humidity sensor is used, there is an aspect based on the humidity at which the growth of viruses, molds, airborne bacteria, allergen components, etc. becomes active, that is, the optimum humidity. When the humidity detected by the humidity sensor is within the range of the optimum humidity, before the activated gas reacts and disappears, the blowing amount of the blowing unit that blows air to the space where the activated gas is released is increased. A large amount is sent to the target space. In addition, when the humidity is outside the optimum humidity range, the air flow rate is set to be reduced. The optimum humidity varies depending on the type of microorganism, and can be changed depending on what is to be removed.

  Here, typical optimum humidity is exemplified. In the case of viruses, it is generally 50% or less, in the case of fungi, it is generally 50% or more, and in the case of bacteria, it is generally 50% or more.

  The object sensor can discriminate the azimuth, number, size, surface shape, etc. of the object. When living organisms are present in the activated gas discharge space, viruses and the like are likely to be generated. Therefore, when the amount of air blown by the blowing unit for blowing air to the space where the activated gas is released is increased, and there are no living organisms It is sufficient to reduce the air flow rate.

  Moreover, a biological sensor is illustrated as a sensor which detects the generation | occurrence | production state of a microbe directly. Examples of biological sensors include enzyme sensors and microbial sensors. A biological sensor is a sensor that detects the presence or absence of a specific substance and its concentration using microorganisms or the like. When the concentration of virus or the like is greater than or equal to a value that greatly affects animals in the activated gas discharge space, the amount of air blown by the blower that blows air into the space where the activated gas is released is increased. If the density of the gas etc. is lower than that, the air flow rate may be reduced.

  With the configuration as described above, in an environment in which a floating virus or the like is activated, an environment in which the concentration of the virus or the like is high, or an environment in which the resistance of an animal is reduced, the air flow rate is increased to increase the concentration of the activated gas. By filling the target space, it is possible to improve the sterilization performance and reduce the adverse effects on the growth of animals and plants due to the growth of the bacteria. In cases other than the above-described environment, that is, in other words, energy saving can be realized by reducing the amount of blown air.

  In addition, it is possible to simultaneously increase (or decrease) the amount of air blown by the blower of the blower that blows air into the space where the activated gas is released and the blower of the blower that blows air to the other space in the opposite direction. For example, the amount of air blown into the space from which the activated gas is released is almost the same as the amount of air blown into the other spaces, so the air in the space from which the activated gas is efficiently released Can be replaced, which is preferable.

  In the above configuration, the air flow rate of each air blowing unit is increased or decreased by the sensor signal, but a timer, a strength of the air flow rate of each air blowing unit, a switch that can input ON / OFF, etc. are input to the control unit. The input means may be interlocked. As an example of a timer, if a user's desired time is input, only the air blowing means that exhausts the activated gas discharge target space where animals and plants are present is differential during that time. There is one that operates both the air blowing means that performs the operation and the air blowing means that sends air to the target space. According to this configuration, when cleaning the breeding room, if the user inputs, for example, 30 minutes, only the air blowing means that exhausts the activation gas discharge target space while the user cleans the breeding room. Can differentially discharge malodors, chemical odors, etc. generated by cleaning. And after that, it is possible to operate both the blower fan for exhausting air and the blower fan for sending air to the target space to introduce the activated gas into the target space and exhaust the exhaust gas.

  This activated gas generator can be used for animal and plant breeding facilities, but the effect of this device is not limited to this and can be used for other applications. is there. For example, it can be used in various living spaces such as homes, buildings, and hospitals, and manufacturing spaces such as clean rooms and factories.

  Thus, if an activated gas generator is provided and activated gas is released into the breeding room, floating bacteria and floating bacteria in the indoor space of the breeding room are sterilized (concepts including sterilization and low activation of bacteria) The same shall apply hereinafter) and can prevent bacterial growth. Therefore, the hygienic condition in the breeding room can be maintained well, and infection of animals and plants with bacteria and bacteria can be prevented. In addition, it is possible to prevent infecting humans involved in the breeding operations of the breeding facility and those who appreciate animals and plants, and the influence on the environment around the breeding facility. In addition, the odor component can be actively decomposed.

An activated gas refers to a gas containing reactive particles such as positive ions and / or negative ions, plasma, or radicals. It reacts with microorganisms and dust in the air, and the amount decreases with time. It may be anything that has the characteristics to follow. By using these activation gases, it is possible to positively remove and inactivate viruses, molds, airborne bacteria, allergen components, and odor components. Of these, the case where positive ions and / or negative ions are used as the activation gas is safer and more preferable for the human body. The concentration of the activated gas in the breeding room is preferably at least 150 / cm ³ .

Here, consider ions contained in the activated gas. Ions can be broadly classified into two types: positively charged positive ions and negatively charged negative ions. When the activation gas contains ions, the inclusion component is classified into three conditions: a case where only positive ions are contained, a case where only negative ions are contained, and a case where both positive ions and negative ions are contained. be able to. Any of these conditions may be adopted, but among these three conditions, the effect of inactivating the virus, mold fungus, airborne fungus and allergen component in the space or deodorizing the odor component is the greatest. Is a case containing both positive ions and negative ions, it is preferable to contain both positive ions and negative ions, and further, the concentration of each ion in the breeding room is at least 150 / cm ³ . Is preferred. If each ion concentration is set to 150 cells / cm ³ or more, viruses and the like in the breeding room can be sufficiently inactivated, but if the ion concentration is lower than 150 cells / cm ³ , the breeding room is sufficiently The virus inside cannot be inactivated. In addition, although it is desirable that the ion concentration of the entire breeding room satisfies the above condition, it is possible to obtain a certain effect even when a part of the breeding room does not satisfy the above condition. For example, a certain effect can be expected when the ion concentration condition is satisfied in the vicinity of animals and plants. Desirably, in the case of animals, it is desirable that the vicinity of the mouth and nose for breathing satisfy the ionic condition.

The positive ion is preferably an ion composed of H ⁺ (H ₂ O) _m (m is an arbitrary natural number), and the negative ion is preferably an ion composed of O ₂ ⁻ (H ₂ O) _n (n is an arbitrary natural number). . When these positive ions and negative ions are simultaneously generated in the air, they undergo a chemical reaction to generate hydrogen peroxide H ₂ O ₂ or hydroxy radicals · OH which are active species. These hydrogen oxides H ₂ O ₂ or hydroxy radicals · OH exhibit extremely strong activity, and thereby airborne bacteria, viruses, and allergen components can be effectively removed and inactivated.

  It is preferable to provide a blowing means for forming a flow of air in a certain direction in the breeding room. If a flow of air in a certain direction is formed in the breeding room, the air in the breeding room can be prevented from flowing out of the breeding room. The direction of the air flow is not particularly limited, but it is not a surface that can ventilate outside the breeding room such as a fence, but a flow that faces the outside of the breeding room such as the ground or a wall and cannot be ventilated. preferable.

  In order to prevent the air in the breeding room from flowing out, it is preferable to provide suction means for sucking the air in the breeding room. The activated gas released into the breeding room can be prevented from flowing out to the space outside the breeding room, the floating bacteria in the room can be prevented from flowing out into the environment around the breeding room, and the bacteria in the breeding room can be effectively sterilized. can do.

  Note that it is more preferable to provide both the air blowing means and the suction means. If the air blowing means and the suction means are provided at positions facing each other, an air flow from the air blowing means toward the suction means can be formed in the breeding room, and the air can be discharged to the outside by the suction means.

  Animals and plants bred in an environment where activated gas is released as described above grows in an ideal environment with little influence from viruses, fungi, planktonic fungi, allergen components, and malodorous components. . Therefore, in the case of animals used for viewing at zoos, aquariums, etc., it is possible to obtain the advantage of a long life.

  Further, the present invention is not limited to a large breeding facility, but can be applied to a small breeding facility for carrying animals. In that case, a portable power source such as a battery, a solar cell, or a fuel cell can be used as a power source for the activated gas generator, the blowing unit, and the suction unit.

  The animal and plant breeding method of the present invention is characterized in that an activated gas for sterilizing airborne bacteria is released into the animal and plant breeding room, and the animal and plant are raised in the breeding room. The breeding method is a method for breeding, producing, and growing animals such as animals and plants. In this way, if activated gas is released into the animal and plant breeding room and the animal and plant are reared in the breeding room, floating bacteria and airborne bacteria in the breeding room space can be sterilized, preventing the growth of bacteria. Can do. Therefore, the hygienic condition in the breeding room can be maintained well, and infection of animals and plants with bacteria and bacteria can be prevented. In addition, it is possible to prevent infecting humans involved in the breeding operations of the breeding facility and those who appreciate animals and plants, and the influence on the environment around the breeding facility. In addition, the odor component can be actively decomposed.

  In the above method, it is preferable to use positive ions and / or negative ions or plasma as the activation gas. By using these activation gases, it is possible to positively remove viruses, molds, airborne bacteria, allergen components, and odor components. Among them, in particular, the case where positive ions and / or negative ions are used as the activation gas can be taken as a safer and most preferable method for the human body.

In the above method, positive ions are ions composed of H ⁺ (H ₂ O) _m (m is an arbitrary natural number), and negative ions are O ₂ ⁻ (H ₂ O) _n (n is an arbitrary natural number). Are preferred.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, this invention is not restrict | limited by embodiment shown below.

<First Embodiment>
FIG. 1 is a diagram showing an outline of the breeding facility 1 of the first embodiment, FIG. 2 is a perspective view of an ion generating element 7, and FIG. 3 is a waveform diagram of a voltage applied to the ion generating element 7 of the ion generating device 4. . In this embodiment, the case where it is used in the zoo breeding facility 1 will be described. Moreover, as an active gas containing component, positive ions composed of H ⁺ (H ₂ O) _m (m is an arbitrary natural number) and negative ions composed of O ₂ ⁻ (H ₂ O) _n (n is an arbitrary natural number). However, the present invention is not limited to this, and plasma may be used. Here, the animals and plants are shown as having raised animals 2 such as lions, but are not limited thereto.

  The breeding facility 1 includes a breeding room 3 that forms a space in which animals and plants are accommodated, and an ion generator 4 that releases activated gas into the breeding room 3. The breeding room 3 is surrounded by an iron or wooden fence 5 and is formed with a roof 6 installed for safety and wind and rain protection purposes. The lion 2 lives in the breeding room 3. In addition, the structure of the breeding room 3 is not limited to the said form, It can change according to the kind, characteristic, etc. of animals and plants, such as not forming the roof 6. FIG.

  The ion generating device 4 includes an ion generating element 7 that generates ions and a blowing unit 8 that includes a propeller, and is installed on the roof 6 of the breeding room 3. An opening (not shown) is formed in the roof 6, and an ion generator 4 is provided to face the opening, and ions flow into the breeding room 3 from the opening. Further, the ion generating element 7 is arranged on the rear side of the breeding room 3 with respect to the air blowing means 8, and the air blowing means 8 is set so as to send air to the rearing room 3 side through the ion generating device 4. Therefore, when the ion generator 4 is operated, ions can be diffused into the space in the breeding room 3 by forced air blowing by the air blowing means 8. The ion generator 4 is provided near the center of the roof 6 of the breeding room 3. Therefore, ions generated from the ion generator 4 can be released over the entire breeding room.

  FIG. 2 shows a schematic diagram (an example) of the ion generating element 7. A dielectric 9 is provided on the surface of the ion generating element 7, and a dielectric electrode 10 is provided on the back side of the dielectric 9. An ion generating electrode 11 is attached to the surface of the dielectric 9 so as to oppose the dielectric electrode 10. It has been. In FIG. 1 and FIG. 2, the shape of the ion generating electrode 11 is a net shape, but is not particularly limited, and a known needle shape or the like may be used. Furthermore, in order to generate ions more effectively, an electrode pattern shape, an edge shape, a material, and the like can be appropriately determined.

  The ion generating electrode 11 and the dielectric electrode 10 are connected to a high voltage pulse driving circuit 13 through a lead wire 12. The high voltage pulse drive circuit 13 is formed inside the ion generating element 7. In the ion generator 4 having such a configuration, the ion generator 4 is driven (that is, a pulse voltage having a positive / negative voltage peak value of, for example, 2.7 kV is applied between the ion generation electrode 11 and the dielectric electrode 10). ), The air sufficiently contains ions and is released into the space. Air that contains enough ions contains both positive ions and negative ions, and when released into the air, it is effective to sterilize airborne bacteria or deodorize odor components. Can have a significant impact.

A high sterilization effect can be obtained by setting each ion concentration at a position 10 cm away from the generation point of positive ions and negative ions to 10,000 ions / cm ³ or more. In addition, when the ion concentration is 300,000 / cm ³ or more, the residual rate of floating bacteria can be reduced to 10% or less in one hour after the delivery of ions, and sterilization can be performed more rapidly and efficiently. . As an ion concentration measuring apparatus, an air ion counter (model number 83-1001B) manufactured by Dan Kagaku Co., Ltd. is used, and small ions having a mobility of 1 cm ² / V sec or more are measured from the ion generation point of the ion generating apparatus 4. It is detected in relation to the distance. This example is described in detail in Japanese Patent Application Laid-Open No. 2002-95731.

  FIG. 3 is a waveform diagram of voltage used for driving the ion generating element 7 shown in FIG. In order to remove and inactivate mold, viruses, allergens and airborne bacteria among discharge gases, when discharging discharge gas with increased positive and negative ion concentrations into space, a high-frequency AC pulse voltage as shown in FIG. It is preferably used. A pulse voltage on a sine wave that gradually attenuates is applied for T1 seconds, and then a rest time of T2 seconds is set. This cycle is repeated. The conditions of the pulse voltage in the normal normal mode of the ion generator 4 are a sine wave frequency of 20 kHz and a pulse repetition period of 60 Hz. Further, T1 is 1 millisecond, T2 is about 15.7 milliseconds (1000 / 60-1), and the applied peak voltage is +2.7 kV for the positive voltage and −2.7 kV for the negative voltage. By using such a waveform, it is possible to effectively generate only positive and negative ions while suppressing the generation of ozone.

By this discharge, positive ions and negative ions are generated from the ion generating electrode 11. H ⁺ (H ₂ O) _n (n is an arbitrary natural number) is generated as positive ions, and O ₂ ⁻ (H ₂ O) _n (n is an arbitrary natural number) is generated most stably as negative ions. This has been confirmed by precise measurement by mass spectrometry. When these positive ions and negative ions are simultaneously generated in the air, they undergo a chemical reaction to generate hydrogen peroxide H ₂ O ₂ or hydroxy radicals · OH which are active species. These hydrogen oxides H ₂ O ₂ or hydroxy radicals · OH exhibit extremely strong activity, and thereby airborne bacteria, viruses and allergen components can be removed and inactivated.

  The activated gas containing the released ions can remove and inactivate viruses, molds, airborne bacteria, allergen components and malodorous components present in the space inside the breeding facility 1 and prevent adverse effects on the lion 2. Is. An adverse effect is a malodorous component that is infected by viruses, molds, allergen components or airborne bacteria, or that Lion 2 feels uncomfortable.

  FIG. 1 shows a state in which a person 14 who visits the lion 2 (or keeps the lion 2) is present around the fence 5. In this example, air freely passes through the fence 5 between the inside of the breeding room 3 and the outside space where the humans 14 who are visiting (bred) are present. Therefore, in an environment where the breeding room 3 is installed outdoors and the wind is strong, the activated gas released into the internal space where the lion 2 exists (in the case of using the ion generator 4) , Ions) are also diffused to the area where there is a human 14 who is coming (bred). Therefore, although the component of the activated gas reaches the human 14 who is visiting (bred), the activated gas containing ions has no influence on the human body. The safety of ions has been confirmed by testing laboratories.

  Further, the present embodiment is not limited to a large breeding facility, but can also be applied to a small breeding facility for transporting animals. In that case, a battery is used as a power source for the ion generator and the blowing means. Alternatively, it is appropriate to use a portable power source such as a solar cell or a fuel cell.

<Second Embodiment>
FIG. 4 is a diagram showing an overview of the breeding facility 1 of the second embodiment. As shown in FIG. 4, in this embodiment, the activated gas released into the breeding room 3 is prevented from reaching the environment where the humans 14 around the breeding facility 1 exist. That is, a flow is generated in the air in the breeding room 3 of the breeding facility 1 so that the activated gas component is not scattered outside the breeding room 3 and is released in a certain direction. In order to achieve the effect, a plurality of air blowing means 15 are provided so that the air flow is in a certain direction. Further, in order to further enhance the effect, suction means 16 is provided on the surface facing the air blowing means 15. As animals and plants, here, a case where an animal 2 such as a rabbit is bred is shown as an example. Other basic configurations are the same as those in the first embodiment.

  That is, separately from the air blowing means 8 of the ion generator 4, the air blowing means 15 including a plurality of propellers is provided on the roof 6. An opening (not shown) is formed in the roof 6, and air blowing means 15 is provided to face the opening. The air blowing means 15 is provided at the four corners of the roof, and can form an air flow from the roof side to the ground side over almost the entire area in the breeding room 3. In addition, the ventilation means 15 is not limited to said installation position and installation quantity.

  On the ground side, a suction means 16 having a plurality of propellers is provided at a position facing the air blowing means 15. When the suction means 16 is installed at a position facing the air blowing means 15, the air flow from the air blowing means 15 flows straight into the suction means 16, so that the air flow in the breeding room 3 is less likely to be disturbed. Although preferable, it is not limited to this. The suction means 16 is connected to a duct, and the other end of the duct communicates with a space separated from the breeding facility 1 or an air purifier.

  In addition, about the number of the ventilation means 15 and the suction means 16, if the flow of air can be produced in a fixed direction in the internal space of the breeding facility 1, it does not need to be plural. For example, a method of installing one blowing means 15 and suction means 16 having a size equivalent to the area of the roof 6 is also possible. Further, in this embodiment, the direction of air flow is from the roof 6 side to the ground side, but the direction of air flow is not particularly limited, and the air blowing means 15 is provided on the ground side to provide the roof 6 side. Alternatively, the suction means 16 may be provided to form an air flow from the ground side to the roof 6 side.

  FIG. 4 shows a state in which a person 14 who visits (or keeps) the rabbit 2 is present around the fence 5. In the above configuration, when the air blowing means 15 and the suction means 16 are operated, an air flow in a certain direction is formed by the air blowing means 15 from the roof 6 side to the ground side. Therefore, it is difficult for the air in the breeding room 3 to leak out of the breeding room 3 through the fence 5. The air blown by the blowing means 15 is sucked by the suction means 16 and is discharged to the outside through a duct connected to the suction means 16. Therefore, the air in the breeding room 3 is not easily leaked around the breeding room 3, so that the activated gas, floating bacteria, etc. in the breeding room 3 do not leak around the breeding room 3. In this way, not only can it prevent harm to humans 14 due to airborne bacteria and the like, but the activated gas does not reach the environment where humans 14 are present, but is released only into the space where rabbit 2 is present. It can be used more effectively. This is a significant difference from the first embodiment.

  In the present embodiment, a plurality of blowing means 15 and suction means 16 are provided to form a constant flow of air in the breeding room 3 so that the air in the breeding room 3 is released to the outside. Although it is a prevention, an air curtain using a flow of air may be formed on the side surface of the breeding room 3 by providing a blowing means that blows air from above to the entire circumference of the upper part of the side surface of the breeding room 3. The air curtain blocks the room and the outside, and can prevent indoor air from leaking outside.

  In the present embodiment, a control unit (not shown) for controlling the air blowing amount of the air blowing means 15 and the suction means 16 can be provided. This control unit can be set to increase or decrease the blowing amount of the blowing unit 15 and the suction unit 16 simultaneously or individually in conjunction with an instruction from another switch, a signal from a sensor, or the like. By using the breeding equipment having such a configuration, it becomes possible to increase or decrease the air blowing amount of the air blowing means 15 and the suction means 16 simultaneously or individually, and the sterilization performance can be adjusted to a desired level. In addition, it is possible to obtain an effect that air hardly leaks from the breeding room to the outside of the breeding room.

  For example, in addition to the above configuration, a control unit connected to the blowing unit 15 and the suction unit 18, and a temperature sensor (not shown) and a switch (not shown) connected to the control unit are provided in the breeding room 3. Provide. The control unit includes a CPU, a ROM, a RAM, and the like.

  In such a configuration, when the temperature sensor detects the temperature, the detection signal is input to the control unit. When the control unit determines that the detected temperature is within the optimum temperature range for viruses, molds, airborne bacteria, allergen components, and the like set in advance, the blowing unit 15 and the suction unit 16 When it is determined that the air flow rate is outside the optimum temperature range, the air flow rates of the air blowing means 15 and the suction means 16 are simultaneously reduced. In addition, when it exists in the range of the temperature from which an animal's immunity falls, it may take the form which reduces ventilation volume, and increases outside that range.

  Moreover, in the said Example, although the temperature sensor was illustrated, the sensor which can detect the generation | occurrence | production state of microbes, such as a humidity sensor, an object sensor, or a biological sensor, may be used individually or in combination.

  Further, the switch can input ON / OFF of the air blowing means 15 and the suction means 18, its timer function, the intensity of air flow, and the like. For example, as a timer function, if the user inputs and sets a desired time (for example, 30 minutes), the control unit operates only the suction means 18 for 30 minutes, and after 30 minutes, the suction means 18 and the air blowing means. 15 can be operated. In such a configuration, it is not necessary to release the activated gas while cleaning the breeding room. Therefore, it is possible to stop the blowing of the activated gas by stopping the blowing means 15 for a certain time (30 minutes). it can. At this time, since the suction means 18 is operating, indoor air can be discharged to the outside. And after work is completed, both the ventilation means 15 and the suction means 18 can be operated, and discharge | release of activated gas and exhaust of indoor air can be performed. Thus, sterilization and air exchange can be performed effectively.

  Further, the present embodiment is not limited to a large breeding facility, but can also be applied to a small breeding facility for transporting animals. In that case, as a power source for an ion generator, a blowing unit, and a suction unit It is appropriate to use a portable power source such as a battery, a solar cell, or a fuel cell.

<Third Embodiment>
FIG. 5 is a diagram showing an outline of the breeding facility 1 of the third embodiment. As shown in FIG. 5, in this embodiment, the example of the chicken farm which breeds the chicken 2 is shown. In this figure, only the area where the chicken 2 feeds is drawn without drawing the whole breeding. The breeding room 3 of the breeding facility 1 in the present embodiment is partitioned by a fence 5 so that the chickens 2 enter one bird, and the chickens 2 can eat the feed given to each. A food container is provided, and an egg container 18 is provided for containing eggs laid by the chicken 2. Other basic configurations are the same as those in the first embodiment.

  Also in the chicken farm of this embodiment, the ion generator 4 is installed on the roof 6 of the breeding room 3. When the ion generator 4 is operated (that is, the ion generating element 7 and the air blowing means 8 are operated), viruses, molds, airborne bacteria, and allergen components in the interior of the breeding room 3 can be removed and inactivated, and at the same time Since it is released to the chicken 2 in the room 3, the risk of the chicken 2 in the breeding room 3 being infected by bacteria, viruses, allergen components, etc. can be avoided, which is very effective.

  Further, ions as the activation gas are released not only to the chicken 2 but also to the eggs laid by the chicken 2. Therefore, mold or the like does not adhere to the surface of the egg, and damage caused by bacteria, viruses or allergen components can be prevented. Therefore, when the egg is used as food, the risk of the human 14 eating the egg being affected is greatly reduced.

<Fourth Embodiment>
FIG. 6 is a diagram showing an outline of the breeding facility of the fourth embodiment. As shown in FIG. 6, in this embodiment, an example of a breeding facility for breeding birds for viewing is shown. The major difference from the first embodiment is not only in the breeding room 3 of the animal 2 such as the bird for viewing, but also in the space where the human 14 who is watching (or breeding) the bird 2 exists. The point is that the activated gas is released. Other basic configurations are the same as those in the first embodiment.

  Specifically, the breeding facility 1 in the present embodiment includes a breeding room 3 that accommodates animals 2 such as birds for viewing so as not to escape, a structure 19 that surrounds the breeding room 3, and a roof 6 of the structure 19 And the ion generator 4 provided in the above. The ion generator 4 is provided to face an opening (not shown) formed in the roof 6 of the structure 19, and allows ions to flow into the structure 19 from the opening. The ion generator 4 is provided near the center of the roof 6 of the structure 19. Therefore, ions generated from the ion generator 4 can be discharged over the entire area of the structure 19.

  The material and form of the structure 19 are not particularly limited, and examples thereof include metal, wooden, reinforced concrete, resin, and glass. Since the breeding room 3 is inside the structure 19, the breeding facility 1 of this embodiment is suitable for breeding animals and plants that are sensitive to weather changes such as rain and temperature.

  FIG. 6 shows a state in which a human 14 who comes to see (bred) the bird 2 is present around the breeding room 3 in the structure 19. When ions are released from the ion generator 4, viruses, fungi, allergen components, and floating bacteria in the structure 19 including the inside of the breeding room 3 are removed and inactivated. It is possible to prevent the animal 2 and the human 14 coming to visit (bred) from being infected.

  In the present embodiment, unlike the first embodiment, from the beginning, the ions generated intentionally by the ion generator 4 and the animal 2 such as a bird for viewing and the like have been visited (see FIG. Attempting to irradiate both humans 14).

<Fifth Embodiment>
FIG. 7 is a diagram showing an outline of the breeding facility 1 of the fifth embodiment. As shown in FIG. 7, in the present embodiment, an example of a breeding facility 1 for breeding birds for viewing is shown. As animals and plants, the case where aquatic animals 2 such as fish and amphibians are bred is shown here as an example. Aquatic animals 2 such as fish and amphibians are present in the aquarium (breeding room 3). In order to breed aquatic animals, the aquarium (breeding room 3) is configured with a plate material 5 instead of a fence so that the water inside does not spill and is sealed. Moreover, as long as there is no aquatic animal flying in the air, it does not matter whether the roof 6 of the breeding room 3 is installed. Other basic configurations are the same as those in the first embodiment.

  In this embodiment, as shown in FIG. 7, the ion generator 4 is installed in the plate-shaped fixing jig 20 provided so that a part of upper surface of the water tank (breeding room 3) may be covered. In order to diffuse ions throughout the water tank (breeding room 3), the ion generator 4 is preferably provided near the center on the upper surface of the water tank (breeding room 3). When the ion generator 4 is operated, ions as the activation gas are released into the area A that does not contain water in the water tank (breeding room 3). Ions do not penetrate into the region B containing water. Ions will end up in the atmosphere.

  When the ion generator 4 is activated, ions as an activation gas are released into the water area A in the aquarium (breeding room 3), and viruses, molds, planktonic bacteria, allergen components, and malodorous components are removed or not. Once activated, the water area is cleaned.

  Even aquatic animals such as fish and amphibians are not completely present in the underwater region B, and sometimes face the water region A for the purpose of breathing and eating food. Therefore, in consideration of such a situation, the ion generator 4 is used to release ions as the activation gas into the water region A, thereby exerting an effective action on aquatic animals such as fish and amphibians. Can do.

<Sixth Embodiment>
FIG. 8 is a diagram showing an outline of the sixth embodiment. In the present embodiment, the concentration of the activated gas that can inactivate the virus is tested. As in the first embodiment, the ion concentration is a concentration at a position 10 cm away from the ion generation point, and an air ion counter (model number 83-1001B) manufactured by Dan Kagaku Co., Ltd. is used as the measuring device. Using.

As shown in FIG. 8, this experiment uses a 1 m ³ sealed box as an example of a space corresponding to the breeding room 3, and in the breeding room 3, air blowing means 8 including an ion generating element 7 and a propeller Is provided, and positive ions and negative ions released from the ion generating element 7 are diffused into the breeding room 3. In this breeding room 3, the sprayer 20 sprays the virus and diffuses it in the breeding room 3, and the virus in the space in the breeding room 3 is collected by the collector 21 at regular intervals to inactivate the virus. The effect has been confirmed. As in the first embodiment, the ion generator 4 applies positive and negative voltages to the discharge electrodes, thereby positively forming H ⁺ (H ₂ O) _m (m is an arbitrary natural number). It is designed to emit negative ions composed of ions and O ₂ ^— (H ₂ O) _n (n is an arbitrary natural number).

  The sprayer 20 sprays liquefied feline coronavirus (FIPV: 79-1146 strain) into the breeding room 3. Coronavirus is a pathogenic virus known to infect livestock, and is believed to cause respiratory disease, hepatitis, and enteritis. It is also believed to cause upper respiratory tract inflammation in humans.

  The virus solution collected by the collector 21 is subjected to a test for TCID50 (the amount of virus that infects 50% of the cultured cells) by cell culture (cat kidney cell: fcwf4 p86 strain), and the infectivity of the collected virus is examined. It was. The lower the infectivity of a virus, the more inactivated the virus is.

In this embodiment, when ions are generated (the ion concentration in the breeding room is about 150 ions / cm ^{3 for} positive and negative ions and 7,000 / cm ³ for each), ions are generated as a comparative example. When the test is not performed (the ion concentration in the breeding room is about 50 ions / cm ³ each for positive and negative ions), the test is performed under a total of three conditions, and the effect of the ion action time in the breeding room 3 on the TCID50 of the virus Examined. The positive / negative ion concentration in the space is adjusted by intermittently driving the power source of the ion generator 4.

The experimental results are as follows. FIG. 9 shows the time dependence of TCID 50 when the space average ion concentration is 150 positive / negative ions / cm ³ respectively.

  According to this, it can be seen that the infectivity of the virus solution collected during 10 minutes of ion treatment time of 40 to 50 minutes is reduced by 98.8% compared to the case where the ion generator 4 is not operated. It was found that this ion concentration can sufficiently inactivate the virus. In the figure, “no ions” means that the ion generator 4 is not operated, and “with ions” means that the ion generator 4 is operated.

FIG. 10 shows the time dependency of TCID50 when the spatial average ion concentration of each positive and negative ion is 7,000 / cm ³ .

  According to this, it can be seen that the infectivity of the virus solution collected during 10 minutes of ion treatment time of 30 to 40 minutes is reduced by 99.7% compared to the case where the ion generator 4 is not operated. It was found that this concentration can sufficiently inactivate the virus.

From the above, the air average ion concentration of each positive and negative ion needs to be at least 150 / cm ³ . If it is less than that, the virus cannot be sufficiently inactivated.

As described above, by releasing at least 150 ions / cm ³ or more of positive and negative ions by the ion generator 4, it is possible to greatly reduce the infectivity of viruses floating in the space. In the present embodiment, dedicated devices such as the virus sprayer 20 and the virus collector 21 are used. However, when a virus-infected animal and a non-virus-infected animal are raised in the breeding room 3 at the same time, the virus infection The effect of reducing the probability of virus infection due to virus release from animals to non-virus-infected animals can be exhibited. In that case, by setting the concentration of at least positive ions and negative ions to 150 / cm ³ , the effect of suppressing disease infection inside can be exhibited.

  With regard to the setting conditions of the ion concentration that can be expected to suppress the above-mentioned disease infection, a certain effect can be obtained if it is realized in a part of the animal and plant breeding environment. It is desirable that the ion concentration is realized at a place where animals and plants are arranged. Furthermore, it can be expected that the disease infection is effectively suppressed by satisfying the condition of the ion concentration in the respiratory organ, that is, the position of the mouth or nose of the reared animal.

  In this example, an example using a suspended feline coronavirus was shown. However, the effect of the present invention has been confirmed in an influenza virus, and is not limited to feline coronavirus. The same effect can be exerted against pathogenic substances such as viruses or bacteria.

<Seventh Embodiment>
FIG. 11 is a diagram showing an outline of the breeding facility according to the seventh embodiment. In the present embodiment, rats 2 (10 males and 10 females) as animals and plants are bred in a breeding facility, and the effectiveness of activated gas for rat growth is verified. The breeding facility 1 can of course be used for animal and plant breeding. In particular, it is suitable for an animal breeding facility in which virus infection such as laboratory animals such as rats and mice should be completely eliminated.

  The breeding facility 1 is divided into a box-shaped breeding room 3 in which animals and plants are accommodated, an air introduction duct 22 and an air exhaust duct 23 connected to an opening formed in the breeding room 3, and the breeding room 3. Alternatively, a rearing cage 24 for accommodating a plurality of individuals, a bulky wind tunnel 25 for collecting air from the air introduction duct 22 to animals and plants in the rearing cage 24, and ions provided at the tip of the wind tunnel 25 And generating element 7.

  The breeding room 3 preferably has a sealable structure such as a glass plate in order to completely shut out infection such as viruses. The rearing cage 24 is not particularly limited, but is composed of a net-like metal material or the like.

  An openable / closable opening / closing window 26 is formed on the side of the breeding room 3 so that the breeder can take care of feeding and watering the rat. The open / close window 26 most desirably has a function of blocking the flow of air inside and outside the breeding room 3, but for convenience such as resting, a part of air such as a lattice or a net is used. A portion capable of diffusion may be provided. Even in that case, as will be described later, since a forced air flow from the air introduction duct 22 to the air exhaust duct 23 is formed, the air passes through the inside and outside of the breeding room 3 through the opening / closing window 26. It can be suppressed and infection such as viruses can be reduced.

  The installation locations of the air introduction duct 22 and the air exhaust duct 23 on the side opposite to the side connected to the breeding room 3 introduce air from the outside of the breeding room 3, and supply air to the outside of the breeding room 3, respectively. Although it will not specifically limit if it can exhaust, in order to prevent infection with the virus etc. to the animals and plants 2 in the breeding room 3, it is preferable to connect with the air cleaner which can remove a virus. The air introduction duct 22 and the air exhaust duct 23 need to be provided with air blowing means on either side in order to form an airflow flowing from the air introduction duct 22 side to the air exhaust duct 23 side, preferably both. It is desirable to provide it.

  According to the above configuration, the air outside the breeding room 3 is sucked from the air introduction duct 22 by the blowing means, and the air passes through the wind tunnel 25 and is blown into the breeding cage 24 together with the ions generated by the ion generating element 7. Finally, it is discharged out of the breeding room 3 through the air exhaust duct 23.

  As described above, since the airflow inside the breeding room 3 is provided with the air supply / exhaust equipment so that air is forced to flow from the air introduction duct 22 to the air exhaust duct 23, the breeding room 3 through the opening / closing window 26 is provided. Since the exchange of air between the inside and outside of the mouse is reduced, it is possible to suppress the arrival of viruses and the like between the rat 2 and the human without being inactivated. As a result, mutual infection between the human and the rat is possible. It becomes possible to lower the sex.

  The following experiment was conducted using the breeding facility having the above configuration. In this experiment, clean air corresponding to 15 ventilations per hour is blown into the breeding room 3 from the air introduction duct 22 and discharged from the air exhaust duct 23. Air containing positive and negative ions is supplied from the ion generating element 7, supplied to the living area of the rat 2, and a reduction in the concentration of viruses and the like released from the rat 2 is realized. Due to this effect, when a part of the rat 2 becomes a specific disease and releases a pathogenic virus around it, the new morbidity of the healthy rat 2 is suppressed, and the healthy life of the whole rat 2 is reduced. It can be expected to achieve a long life.

In this example, the ion generating element 7 equivalent to that shown in the first embodiment is used to release ions, and the positive and negative ion concentrations in the breeding cage 24 are set to 20,000 / cm ^3. Alternatively, the animals were reared under the conditions of 3,000 / cm ³ and no ion release (positive and negative ion concentrations of about 50 / cm ³ ) under completely separated conditions. The conditions other than the generation of ions are the same including the air blowing. Also, it was confirmed that the ozone concentration inside the breeding room 3 was 0.01 ppm or less.

  In this example, the growth state of rat 2 under the above three conditions was examined using healthy rat 2 (8 weeks old). A graph of the change in average body weight of males and females under each condition is shown in FIG. 12 for males and FIG. 13 for females.

  According to this, there was no significant difference in the weight change between males and females due to the above-mentioned ion 3 conditions. In addition, no abnormalities were observed in all the males and females in the general state observation (eye state, urine state, food intake), and as a result, it was confirmed that good breeding conditions of the rats were maintained.

  Therefore, since the reared rat 2 was healthy, no change affecting health was observed due to the presence or absence of ions, and it was confirmed that ions can be safely used under this condition. In addition, when the ion generator 4 is driven, a pathogenic virus or the like contained in the air around the rat 2 is inactivated when a part of the rat 2 or a caring person becomes an airborne disease. Thus, it is possible to expect the effect of suppressing the disease infection of rat 2 or human and maintaining good health.

<Eighth Embodiment>
FIG. 14 shows an ion generator 4 in the eighth embodiment. The present ion generator 4 is an ion generator 4 applicable to the breeding facility of the present invention. The present ion generator 4 has a blower unit including a blower path and a blower unit and an ion generator unit, and is attached to an opening provided on the wall surface of the breeding room 3 to release ions by the ion generator unit. In addition, it is possible to realize the function of exhausting the indoor air from the breeding room 3 to the outside of the breeding room 3 with a single device while the ions are blown into the room by the blower. For this reason, construction becomes easy and cost reduction can be realized.

  Specifically, as shown in FIG. 14, two ducts 27 and 28 that are air blowing paths are provided so as to penetrate through a flat mounting plate 29. The mounting plate 29 is fixed with screws or the like so as to close the opening of the wall surface of the breeding room 3 so that one side of the mounting plate 29 is inside the breeding room 3 and the other side is outside the breeding room 3. Thereby, it arrange | positions so that one end of both the ducts 27 and 28 may be located inside the breeding room 3, and the other end may be located outside the breeding room 3, and both ducts will be in the state which communicates the outside of a breeding room. Also, fans 30 and 31 as air blowing means are provided in the ducts 27 and 28, respectively, and the air blowing directions are set to be opposite to each other. That is, one duct serves as an intake duct 27 that blows air outside the breeding room into the breeding room, and the other duct serves as an exhaust duct 28 that exhausts air inside the breeding room to the outside of the breeding room.

  Further, the intake duct 27 is provided with an ion generating element 7 which is an ion generating means on the inside of the breeding room from the fan 30, and ions are blown into the breeding room 3 together with the air introduced from the outside of the breeding room 3.

  Further, the mounting plate 29 is provided with a control unit 32 that is connected to the fan 30 and the fan 31 and controls the operation thereof, and has a function of operating in conjunction with the air flow rate of the fan 30 and the fan 31. ing. The control unit 32 includes a CPU, a ROM, a RAM, and the like. The control unit 32 is connected to the switch 33 and the temperature sensor 34, and has a function of increasing or decreasing the air flow rate of the fan 30 and the fan 31 simultaneously or individually according to the signal. The temperature sensor is provided in the breeding room 3 and detects the temperature in the breeding room. The temperature sensor may be attached to the surface of the attachment plate on the inside of the breeding room.

  In such a configuration, when the temperature sensor 33 detects the temperature, the detection signal is input to the control unit 32. When the control unit 32 determines that the detected temperature is within a preset optimum temperature range for viruses, molds, airborne bacteria, allergen components, and the like, the blowing unit 15 and the suction unit When the air flow rate of 16 is increased and it is determined that it is outside the optimum temperature range, the air flow rates of the air blowing means 15 and the suction means 16 are reduced. In addition, when it exists in the range of the temperature from which an animal's immunity falls, it may take the form which reduces ventilation volume, and increases outside that range.

  In addition, although the temperature sensor was illustrated in the said Example, you may use the sensor which can detect the generation | occurrence | production state of microbes, such as a humidity sensor, an object sensor, or a biological sensor individually or in combination.

  Further, the switch 34 can input ON / OFF of the fan 30 and the fan 31, its timer function, the intensity of air flow, and the like. For example, as a timer function, if the user inputs and sets a desired time (for example, 30 minutes), the control unit 32 operates only the fan 31 on the exhaust duct 28 side for 30 minutes. 31 and the fan 30 on the intake duct 27 side can be operated. With such a configuration, it is not necessary to release the activated gas while cleaning the room such as the breeding room. Therefore, the fan 30 on the side of the intake duct 27 is stopped for a certain time (30 minutes) and activated. The blowing of gas can be stopped. At this time, since the fan 31 on the exhaust duct 28 side is operating, indoor air can be discharged to the outside. Then, after the work is completed, both the fans 30 and 31 can be operated to release the activated gas and exhaust the indoor air. Thus, sterilization and air exchange can be performed effectively.

  With such a configuration, in conjunction with the switch 34 and the sensor 33, the amount of activated air released is fluctuated, the activated gas is released in a large amount at a high speed and leaks from the target space. Since the amount of air can be suppressed as much as possible, optimal sterilization suitable for breeding can be performed.

  The number of intake ducts 27 and exhaust ducts 28 is not necessarily one, and a plurality of intake ducts 27 and exhaust ducts 28 may be provided. In addition, it is desirable that the total air blowing amount of each of the intake duct 27 and the exhaust duct 28 is substantially the same. For example, when the ratio of the intake air amount and the exhaust air amount is within the ratio of 1: 2 or 2: 1. If it exists, effects, such as virus inactivation, can fully be acquired. In FIG. 14, the ducts and fans of the intake duct 27 and the exhaust duct 28 have similar shapes, but may have different shapes as necessary.

  Furthermore, although the intake duct 27 or the exhaust duct 28 has a short length in FIG. 14, it may be extended to an appropriate place. Further, a filter may be provided in the intake duct 27 or the exhaust duct 28 or connected to an air cleaner. Since movement and diffusion of dust and pathogenic bacteria can be prevented, safer operation of the apparatus can be achieved. Furthermore, it is good also as a structure which provides a temperature or humidity control function, and stabilizes an indoor environment by providing a heat exchanger integrally. Furthermore, the intake duct 27 and the exhaust duct 28 do not have to be completely separate systems, and the intake duct 27 and the exhaust duct 28 are partially coupled to ensure the indoor temperature and the like and the concentration of the activated gas. It is good also as a structure.

  In the above-described embodiment, the ion generator 4 is provided on the wall surface of the breeding room 3. However, as in the fourth embodiment, the activated gas is released into the structure 19 surrounding the breeding room 3. In such a case, it is possible to appropriately deal with such cases as providing the ion generator 4 on the wall surface of the structure 19.

  Moreover, although the ion generator 4 shown in the present embodiment can be used for animal and plant breeding facilities, it is possible to obtain an effect. However, the utility of the present apparatus is not limited to this, and it can be applied to other applications. The ion generator 4 itself has the value of the invention. For example, it can be used in various living spaces such as homes, buildings, and hospitals, and manufacturing spaces such as clean rooms and factories. If this ion generator 4 is attached to the wall surface opening of such a facility, the activated gas can be generated by the activated gas generating means, and the activated gas can be diffused into the facility space by the blowing means. The air in the facility space can be exhausted by the exhaust means. When used in such a space, it is possible to achieve at low cost to suppress the diffusion of pathogenic bacteria, viruses, etc., and various pollutants from the target space to another space.
