Description

Specification

Animal and plant breeding facilities and methods, animal and plant bred thereby, and activated gas generators

Technical field

The present invention relates to an animal and plant breeding facility, an animal and plant bred using the same, an activated gas generating device, a method of producing an animal and plant, and an animal and plant bred by the method.

Background art

[0002] Animal and plant breeding facilities are used in various fields. Specifically, in the case of animals, there are places such as a zoo, an insect garden, a botanical garden, a poultry farm, a pig farm, a cowshed, a milking farm, a ranch, an aquarium, a pet shop, and a farm. The facilities used in these places are formed by surrounding the four sides with metal structures made of rods, meshes, or plates, and animals are kept in their internal space (breeding room). Things. In the case of plants, places such as farms and mushroom farms are mentioned, and the facilities used in these places are greenhouses using fats such as vinyl alcohol.

[0003] What is important in a breeding facility for these various animals and plants is hygiene management.

Sanitary management in animal and plant breeding facilities requires consideration of the following three major points.

[0004] The first viewpoint is that it is necessary to consider the effect on animals and plants.

Inadequate hygiene controls can lead to flora and fauna becoming infected with viruses and vehicle bacteria, airborne bacteria, and allergen components that float in the room. For example, when considering a breeding facility in a poultry farm or a pig farm, if chickens and pigs in the breeding room are infected with a virus and die all at once, the cost damage will be enormous. In addition, infected animals must take appropriate measures, for example, by incinerating all chickens and pigs in their poultry farms and pig farms, resulting in a large cost loss. In addition, even when raising rare flora and fauna of special varieties in animal and animal breeding facilities at zoos, aquariums, botanical gardens, etc., if there are rare species of flora and fauna, they will be suspended in the space. Depending on the ingredients In some cases, it may not be possible to take appropriate measures for symptomatic treatment of infection.

[0005] The second viewpoint is that it is necessary to consider the effects on humans involved in animal and plant breeding facilities. If the hygiene management in the animal and plant breeding facilities is not sufficient, humans engaged in the breeding of animals and plants in the facility or who are observing the animals and plants in the animal and plant breeding facilities for ornamental use However, there is a possibility that it will be infected with viruses, fungi, and bacteria that float in the facility space, and allergen components. In addition, there is also a problem that human beings may feel extremely uncomfortable due to body odor from animals and plants and odor such as feces. Furthermore, the air in the internal space where the animals and plants are present leaks to the external space, and it is avoided because it drifts as odor.

[0006] The third viewpoint is that it is necessary to consider the effect on the local environment where the breeding facilities are installed. When air in the internal space of animal and plant breeding facilities is released into the external space, odors that local people find unpleasant may be released. In addition, viruses and plant-borne viruses, viable bacteria, airborne bacteria, and allergen components may be released to the local environment where breeding facilities are installed. Insufficient hygiene control in animal and plant breeding facilities may affect unrelated environments around the facilities.

[0007] As described above, it can be seen that hygiene management is extremely important in animal and plant breeding facilities! Of course, hygiene measures have been adequately taken in these animal and plant breeding facilities, but they are still not perfect, and cases of infection from diseases caused by animal and plant transmission have been reported. You.

[0008] Therefore, in order to solve the above-mentioned three problems, the following measures are currently taken as measures to be taken in the hygiene of animal and plant breeding facilities.

[0009] (A) A method of performing a cleaning treatment in a breeding facility

It is a method of frequently cleaning wastes such as animal and plant excrement and manure existing in the internal space of the facility, or frequently cleaning equipment in the facility.

[0010] (B) How to frequently replace equipment in the breeding facility

For example, frequent changes in feed and drinking water given to animals and plants in the facility. [0011] (c) A method for improving the hygiene of the animals and plants in the breeding facility

For example, a method of removing dirt attached to the skin, feathers, and scales of animals and plants by washing the body surfaces of the animals and plants existing in the internal space of the production facility.

[0012] (D) A method for purifying air in a breeding facility

For example, by circulating the air inside the facility using a filter that uses activated carbon and the like used in known air purifiers, activated carbon can be used to remove viruses, power bacteria, floating bacteria, allergen components, and odor components. This is a method of adsorbing and trying to remove.

[0013] However, the above-mentioned sanitary measures (A) to (D) do not suppress the increase of viruses and viable bacteria / suspension bacteria that increase with time. Increased The meaning was strong! In addition, with regard to odors generated by animals and plants, it was only a matter of removing those floating in the production and breeding space in order, which was a passive method. Therefore, even if these methods are performed once, the virus, bacillus, floating bacteria, allergen components and odor increase immediately, and the same work is routinely performed after a certain period of time. Had to be repeated. Such routine repetitive tasks require a great deal of labor and lead to an increase in the cost of animal breeding and production.

[0014] Of course, as a method of suppressing an increase in cost, it is conceivable to perform automation using dedicated equipment or devices according to the various methods (A) to (D) described above. However, considering the reliability of the equipment itself and sudden accidents, etc., it may be difficult to achieve full automation using a machine, and at the same time, regular management (maintenance) by humans is required. In addition, during regular maintenance, the person in charge of the work may be affected by virus, bacillus, airborne bacteria, or allergen components.

[0015] Further, in the conventional breeding facilities having passive sanitation facilities as described above, the air in the facilities is kept in a clean state by the technology using a filter, and the filter Replacement and cleaning are required.

[0016] Therefore, if a gas containing some effective components (activated gas) is released to the breeding facility, which is not a passive method by using a filter or washing, a proactive method is proposed. Has been. The term “activated gas” used herein is characterized in that a gas containing ozone or ion is used as an effective component of the gas. The following shows a conventional example.

[0017] (1) When the activating gas contains ozone (when ozone has the greatest effect)

For example, in Patent Document 1 (Japanese Patent Application Laid-Open No. Hei 10-113097) and Patent Document 2 (Japanese Patent Application Laid-Open No. Hei 10-113096), as an insect breeding apparatus and an insect breeding method, an intake section, an exhaust section, Alternatively, a method is disclosed in which an ozone generator and a sterilizer are provided in the apparatus. The inventions described in these patent documents are characterized in that the breeding apparatus is not contaminated with a virus by using this method.

Ozone has long been known to have a sterilizing effect and a 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 Application Laid-Open No. 9-243102) describes an invention of a ceiling-embedded air conditioner. Patent Document 3 describes that odor in indoor air is removed and decomposed by the strong and oxidizing power of ozone.

However, when a gas containing ozone is used as the activation gas, it is necessary to consider the harmfulness of ozone itself. In other words, a very small amount of ozone is effective for disinfection and inactivation of viruses, mold fungi, airborne bacteria, and allergen components, and for deodorization of odor components. Become. If the ozone concentration is high, irritation to the respiratory system, eyes, mucous membranes, etc., may have a large adverse effect on the human body. The allowable value of ozone concentration varies depending on the laws and regulations of each country.For example, in Japan, the value of photochemical dioxin (a general term for ozone and other substances containing oxidizing substances as main components) is one hour as an environmental standard for air pollution. It is specified as 0.06ppm or less. Therefore, when a gas containing ozone is used as the activation gas, it is necessary to appropriately manage the ozone concentration. At the same time, ozone has a peculiar pungent odor, and has the disadvantage of being unpleasant.

[0020] (2) When the activation gas contains ions (when the ions have the greatest effect)

In recent years, methods of using ions to inactivate viruses, bacteria, floating bacteria and allergen components in a space, or to deodorize odor components have been attracting great attention in recent years. Using ions in the air, the method of purifying is also conventionally described below. There was such a report. Hereinafter, the effect of ions in the air on animals and plants will be described.

[0021] (a) Developmental effects on animals (mammals)

(a-1) Effects on various animals

According to Non-Patent Document 1 (Edited by Tomio Ryuko and Hisao Sasaki, supervised by the Japan Society for Environmental Health and Science, "Encyclopedia of Air Minus Ion", 2002, published by Human and History Company), published in 1960 by Tchijevsky "Air

Ionization, Its Role in the National Economy, states that air ions significantly increase physical activity, reproductive function, appetite, and body weight in knees, egrets, mice, and sheep. is there. Tchijevsky reported that in pigs, negative ion treatment significantly improved the recovery from disease (bronchitis and toxemia of pregnancy). In addition, it is reported that wool that obtained the wedge strength of oss treated with negative ions was longer, stronger and thinner than those without negative ions. In addition, Tchijevsky reported that when female cows were reared in negative air ions for 47 days, there was a significant increase in milk production, protein and fat content in milk, and body weight (average body weight was 1 cow). Per kg), and sexual activity (reproductive function) and blood catalase levels were also significantly increased by negative ions.

[0022] (a— 2) Effects on pigs

According to Non-Patent Document 1, Mozzherin and co-workers report (1974) that piglets receive 300,000 to 400,000 light anions of Zcm ³ twice daily for 1 month, 1 Irradiation for 30 minutes per dose increased pig's daily weight gain by 7-19%, increased oxygen uptake by 4%, carbon dioxide exhalation by 2%, lung ventilation by 16%, and breathing depth. , A protein digestibility of 8.9%, a fat digestibility of 8.4%, and a fibrin digestibility of 13%.

(B) Growth effect on small animals (insects)

(b-1) Effects on silkworms

According to a joint study by Krueger and Kotaka (1966), the above-mentioned non-patent document 1 shows that the growth rate of silkworm larvae and catalase in bodily fluids are caused by charged polar ions in the air. And peroxidase and cytochrome C acidulase are reported to significantly increase the biosynthesis. In addition, it was reported in Non-Patent Document 1 that it was reported that the above-mentioned ions of the polarity promoted the growth of larvae and caused the onset of spinning earlier, thereby significantly increasing the development of the silk layer. I have.

[0024] (b—2) Effect on bees

According to Tchijevsky (1960), the above-mentioned non-patent document 1 reported that with regard to the application of air ions to the beekeeping industry, an appropriate amount of negative ions reduced bee mortality and increased flight activity. Have been. Tchijevsky reports that during the day, the time during which the flight activity of the bees rises coincides with the time when the natural ion force is at its maximum. In addition, they report that flying activity of bees increases with increasing sunshine dose and air dryness, a basic meteorological factor that promotes atmospheric air ionization.

(C) Developmental effect on plants

(c 1) Impact on crops

In Non-Patent Document 1 described above by Suganuma and Nakayama in Japan (1982), it was described that when exposed to an electric field of 10 to 20 kVZm, the yield was increased in sweet potato and radish.

(C 2) Report by Krueger (1959 and 1962)

The Non-Patent Document 1, was exposed seeds Krueger force Enbata to 10, 000 pieces / cm ³ ions, elongation 60%, fresh weight increased 25-30 percent, component also proteins, nitrogen content And that there was an increase in sugar content. After that, an experiment was conducted to see the effects of ions on plants using barley, lettuce, and endo ゥ. As a result, it was reported that the growth of V and even barley seedlings was suppressed in the absence of ions and in the environment. .

(C3) Report by Yamaguchi and Krueger (1983)

The Non-Patent Document 1, in a nutrient fluid cultivation of Yamaguchi and Krueger force tomatoes, 6, 000-20, when exposed to negative ions 000 / cm ³ (day during the seedlings, then during the day only) Seeding power The time to harvest was shortened by about 2 weeks, and the weekly yield was 50% in the first three weeks, and the cumulative yield was about 27% in the sixth week. Reported. In addition, overall, it is reported that the mineral content is high and the taste is good Has been reported, indicating that there is sufficient potential for practical use.

[0028] Further, Non-Patent Document 1 describes that the results of Krueger's experiment are summarized by Shigemitsu (1999) as follows. For oats, ion exposure had no effect on germination, but dry matter increased in the ion-treated group, and in the negative-ion treated group, the growth was large and the effect of ions was observed as a whole. In addition, barley (radicles) was exposed to 11 000 positive ions / cm ³ and 9,000 negative ions / cm ³ for 15 days for resistance to true brown spot injury and plant height, live weight, and dry weight. Investigations reported that positive ions delayed the onset of disease for 3 days, negative ions did not cause disease, and a slight increase in plant height and dry weight was observed.

[0029] As described above, it has been reported that the method using ions in the air has an effective effect on the breeding, production and management of animals (mammals), insects and plants.

BEST MODE FOR CARRYING OUT THE INVENTION

[0054] The present invention is an animal and plant breeding facility equipped with an activated gas generating device that releases an activated gas into a breeding room that can remove airborne bacteria in the air. Here, the breeding facility is a facility that breeds, produces, and breeds organisms such as animals and plants. Materials for the breeding facility are not particularly limited, and for example, metal materials, wood, plastics such as plastics, glass, ceramics, paper materials, stone materials, cement materials, carbon fiber materials, and the like are preferably used. be able to. When the animals and plants to be bred require a water space such as fish, amphibians and reptiles, it is preferable to adopt a hermetic structure so that water in the breeding room does not leak out. When the animals and plants to be bred can fly in the sky like birds and insects, it is preferable to provide a roof or the like that not only surrounds the sides but block the upper surface.

[0055] The activated gas generating apparatus used in the animal and plant breeding facility of the present invention 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. It may be provided at a position away from the room. Further, it is desirable to provide a blowing means to allow the activated gas to be sufficiently distributed to the inside space of the breeding room, and to diffuse the air containing the activated gas component into the space. ,. Although the form of the blowing means is not particularly limited, for example, a method of diffusing into the space by using a blade used in a fan, or reducing the pressure in the space to contain the activated gas component A new method is to introduce a new gas into the space. Activated gas generation The device is preferably, but not limited to, a device that generates an activation gas by a discharge method or a light irradiation method.

Specifically, the activated gas generating device of the present invention has a plurality of air blowing sections each including an air blowing path and an air blowing unit, and the air blowing directions of some of the air blowing sections and the air blowing directions of the other air blowing sections. However, it is possible to adopt a mode in which the directions are set to be opposite to each other, and at least one of the partial blowing units is provided with the activated gas generating means.

[0057] Examples of the blowing path include a duct such as a duct for guiding air, and one end may be arranged on the space side from which the activation gas is released, and the other end may be arranged on the other space side. An example of the blowing means is a fan, which may be provided in the blowing path. With such a blowing path and a blowing unit that is a blowing means, air can be exchanged between the space at one end of the duct and the space at the other end.

[0058] Further, a plurality of blowers are provided, and a force is preferably set such that the blow direction of some of the blowers and the blow direction of the other blowers are opposite to each other. Here, in the blowing section, the blowing direction of a part of the blowing section is directed to the space intended to discharge the activated gas (the activated gas discharging space), and the blowing direction of the other blowing sections is changed to the corresponding direction. It is provided so as to be away from the space.

[0059] According to the activated gas generator of the preferred embodiment of the present invention, the blowing direction of some of the blowing units is set to the direction of flowing toward the space intended to release the activated gas, and some of the blowing directions are Since at least one of the air blowing units is provided with the activated gas generating means, the air blowing means can diffuse the activated gas into the space. In addition, as long as one end of the blowing unit provided with the activation gas generating means is communicated with the activation gas discharge space, the other end may be closed without communicating with the other space. In addition, the number is not particularly limited as long as the number of blowers is two or more.

[0060] In the activated gas generating apparatus of the present invention, it is preferable that the plurality of air blowing sections in which the air blowing directions are set to be opposite to each other and the active air generating means are unit-shaped. Thus, the functions of generating the activation gas, blowing (diffusing) the activation gas, and exchanging air can be realized only by providing the activation gas generator. Therefore, there is no need to provide a separate blower or the like, which facilitates construction. [0061] Further, the activated gas generating apparatus of the present invention can measure the amount of air blown by each of the air blowing means of a part of the air blowing part and the other air blowing part that reverses the air blowing direction, by using an output signal from a sensor or It is preferable to have a control unit to increase or decrease based on the instruction input. In the case where a plurality of blowers are integrally provided, a single control unit can be linked with the blower of each blower. By having the control unit, it is possible to easily realize a configuration that does not leak the air in the breeding room while changing the sterilization performance in accordance with the change in the increase and decrease of the blowing amount.

[0062] Further, the activated gas generating apparatus of the present invention uses the output signal of the sensor force for directly or indirectly detecting the generation state of a virus, a bacterium, a floating bacterium, an allergen component, or the like, or the state of an animal. It is preferable that the control unit increases or decreases the amount of air blown by the air blowing means of each air blowing unit. With such a configuration, it is possible to effectively remove bacteria at low cost.

[0063] Sensors for detecting the state of generation of bacteria such as viruses, bacteria, suspension bacteria, and allergen components, or the state of animals are limited as long as they can directly or indirectly detect these states. Not something. For example, a temperature sensor, a humidity sensor, an object sensor that can detect the above state indirectly, and a biological sensor that can directly detect the above state can be exemplified, and they can be provided alone or in combination. These sensors may be provided at a location separated from the activated gas generator as long as they are arranged at positions where the respective objects can be detected. The occurrence state of virus, virulent bacteria, floating bacteria, allergen components, etc. refers to the degree of activity of viruses, virulent bacteria, floating bacteria, allergen components, etc. Refers to the amount of allergen components and the like.

[0064] These sensors indicate that the virus or the like is in an activated state, that the concentration of the virus or the like is high, that the resistance of animals in the activated orifice gas discharge space is reduced, or the like. On the other hand, when it is detected that the virus or the like has a high effect on the animals existing in the active gas flow, the control unit sends the air to the space from which the active gas is released. Control is performed to increase the amount of air blown by the blower. On the other hand, when it is detected that the effect of the virus or the like on the animal is low, the control unit performs control so as to reduce the air flow.

[0065] Specifically, an example in which a temperature sensor is used will be described. A temperature sensor for detecting an air temperature is provided in the activated gas generating apparatus of the present invention, and an output signal from the temperature sensor is used to detect the air temperature. In accordance with the fluctuation, the control unit increases or decreases the amount of air blown by the blowing means of the blowing unit that blows air into the space from which the activated gas is released.

[0066] A preferred embodiment of the set conditions is based on a temperature at which the proliferation of viruses, bacteria, suspension bacteria, allergen components and the like is activated, that is, based on an optimum temperature. In a powerful mode, for example, when the temperature detected by the temperature sensor is within the optimal temperature range, the air blowing amount of the air blowing unit of the air blowing unit that blows air into the space from which the activated gas is released is increased, and A large amount of gas is sent to the target space before it reacts and disappears. If the air temperature is outside the range of the optimum temperature, the air flow is set to be reduced. Since the optimum temperature varies depending on the type of microorganism, it can be changed depending on the object to be removed.

Here, a general optimum temperature will be exemplified. Microorganisms can be broadly classified into psychrophilic, mesophilic, and thermophilic microorganisms according to the optimal temperature for their growth.The optimal temperatures for psychrotrophic bacteria are 20 ° C or less, for mesophilic microorganisms 25 to 40 ° C, and for thermophilic microorganisms. 45 degrees or more. It should be noted that since there are many mesophilic bacteria in nature, it is preferable to use the optimal temperature (25 to 40 degrees). The optimum temperature of most bacteria in houses and buildings is generally 5 to 35 degrees Celsius.

[0068] As another setting condition different from the mode based on the optimum temperature, there is a mode based on a temperature that causes a decrease in the physical strength of an animal. It is said that the optimal temperature for humans to be comfortable is between 18 and 26 degrees Celsius. In general, it is considered that when the temperature is above 30 degrees or below 10 degrees, physical strength is reduced. If the physical strength decreases, it becomes easier to control diseases such as influenza, so the temperature should be within a certain temperature range (for humans, for example, 10 degrees or less) or a certain temperature (for humans, for example, 30 degrees or more). In order to improve the disinfection performance, increase the air volume of the air blower of the air blower that blows air into the space from which the activated gas is released, and remove the activated air containing the activated gas in the target breeding space. It is good also as the form which blows a lot. If the air temperature is out of the above range, the air flow is reduced. The temperature that causes the animal's physical strength to decrease depends on the type of the animal and the health condition of the animal, and can be changed as appropriate.

[0069] In the above "increase the amount of air blown by the air blowing means" t, the amount of air blown in this case is such that a large amount of new active gas is sent to the active gas discharge space before the active gas reacts and disappears. In This is the amount of air that can be disinfected to such an extent that viruses and the like in the activated gas discharge space do not affect animals and the like existing in the space. In addition, the above-mentioned “decrease the amount of air blown by the blowing means” t, and the amount of air blown in this case means that the amount is smaller than that in the case of “increase the amount of air blown by the blower means”. In addition, the amount of air that can be disinfected to such an extent that viruses and the like in the activated gas discharge space do not affect animals and the like existing in the space.

[0070] In addition to the temperature sensor, a humidity sensor or an object sensor can be suitably used in the present invention as a sensor for indirectly detecting the state of bacterial generation. When a humidity sensor is used, there is a mode based on the humidity at which the proliferation of viruses, virulent bacteria, floating bacteria, allergen components and the like becomes active, that is, based on the optimal humidity. If the humidity detected by the humidity sensor is within the range of the optimum humidity, increase the amount of air blown by the blowing means of the blower that blows into the space from which the activated gas is released, and the activated gas reacts and disappears. Before sending to the target space. If the humidity is out of the range of the optimum humidity, the air flow is set to be reduced. Since the optimal humidity varies depending on the type of microorganism, it can be changed depending on the object to be removed.

Here, a typical optimum humidity will be exemplified. In the case of a virus, it is generally 50% or less, in the case of a bacterium, it is generally 50% or more, and in the case of a bacterium, it is generally 50% or more.

[0072] The object sensor can determine the orientation, number, size, surface shape, and the like of the object. If an object sensor detects the presence of living organisms in the active gas discharge space, a virus or the like is likely to be generated. Therefore, the amount of air blown by the air blowing means of the air blower that blows air into the space from which the active gas is released. If there are no living organisms, reduce the air flow.

[0073] Examples of the sensor that directly detects the occurrence state of bacteria are biological sensors. Examples of the type of the biological sensor include an enzyme sensor and a microorganism sensor. Biological sensors are sensors that detect the presence or absence of specific substances and their concentrations using microorganisms and the like. Concentration power of virus etc. detected by the biological sensor If the value is greater than or equal to a value that has a great effect on the animals in the active iris gas release space, a blower that blows air to the space where the active iris gas is released If the concentration of virus etc. is lower than that, If you lower the air volume.

With the above configuration, in an environment where floating viruses and the like are activated, an environment where the concentration of viruses and the like is high, and an environment where the resistance of animals is reduced, the amount of air blown is increased to increase the activity. By filling the target space with a high concentration of dani gas, it is possible to improve the germicidal performance and to reduce the adverse effect on the growth of animals and plants due to the growth of bacteria. Further, in a case other than the above-mentioned environment, energy saving can be realized by reducing the amount of air blow.

[0075] The amount of air blown by the air blowing means of the air blowing unit for blowing air into the space from which the activated gas is released and the air blowing means of the air blowing unit for blowing air to the other space in the opposite direction are simultaneously increased in calorific value ( (Or decrease), the amount of air blown into the space from which the activation gas is released is almost the same as the amount of air blown into the other spaces, so that the activated gas is efficiently discharged. This is preferable because the air in the released space can be replaced.

In the above-described configuration, the air volume of each air blowing unit is increased or decreased by a signal from the sensor. However, a switch capable of inputting a timer, the strength of the air volume of each air blowing unit, ONZOFF thereof, and the like to the control unit. And other input means. In the case of using a timer, if a user inputs a desired time, only the blowing means for exhausting the space where the animals and plants are present is activated during that time, and after that time, There is an example in which both a blowing means for exhausting air and a blowing means for blowing air to a target space are operated. According to this configuration, when cleaning the breeding room, if the user inputs, for example, 30 minutes, the ventilation means that exhausts the space for releasing the activated gas while the user cleans the breeding room. Only the device operates to release the odor and chemical odor generated by cleaning to the outside. Thereafter, both the blower fan for exhausting air and the blower fan for sending air to the target space can be operated to introduce the activated gas into the target space and exhaust the air. is there.

[0077] The activated gas generating apparatus of the present invention can be used for other applications other than those described above, in which the effect can be obtained by using the apparatus in animal and plant breeding facilities. . 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. [0078] As described above, by providing the active dani gas generator and releasing the active dani gas into the breeding room, it is possible to remove the germs and the germs in the indoor space of the breeding room. (Including activation), and prevent the growth of bacteria. Therefore, it is possible to maintain good hygiene conditions in the breeding room and to prevent infection of animals and plants with bacteria and bacteria. In addition, it is possible to prevent humans involved in the breeding facility's breeding operations, people who appreciate flora and fauna, and effects on the environment around the breeding facility. In addition, odor components can be positively decomposed to be decomposed.

[0079] The activated gas in the present invention refers to a gas containing reactive particles such as positive ions and Z or negative ions, plasma or radical, and reacts with microorganisms and dust in the air. However, any material may be used as long as it has the characteristic that the amount decreases over time. By using these activated gas, it is possible to positively remove and inactivate viruses, bacteria, floating bacteria, allergen components and odor components. Among them, the use of positive ions and Z or negative ions as the active gas is more safe for the human body and is most preferable. The concentration of the activated gas at the position of the animal or plant in the breeding room is preferably at least 150 / cm ³ .

Here, consider the ions contained in the activated gas. Ions can be broadly classified into two types: positively charged positive ions and negatively charged negative ions. The activation gas is classified into three conditions: when it contains ions, when it contains only positive ions, when it contains only negative ions, and when it contains both positive and negative ions. can do. In the present invention, any of the above conditions may be employed. However, in these three conditions, the virus or the bacteria in the space, the floating bacteria, the allergen component is inactivated, or the odor component is deodorized. Is most effective when both positive and negative ions are contained, so it is preferable to include both positive and negative ions. Is preferably at least 150 / cm ³ . If 150 / cm ³ or more to set the respective ion concentrations, a virus, etc. in the well breeding room A low power 150 / cm ³ Yorimoi on concentrations that can be Fukatsui spoon, sufficiently There is a possibility that viruses and the like in the breeding room cannot be inactivated. In the animal and plant breeding facility of the present invention, the ion concentration in the entire breeding room is reduced. It is desirable to satisfy the above conditions, but it is possible to obtain a certain effect even in a case where a part of the breeding room satisfies the above conditions. For example, a certain effect can be expected when the above ion concentration condition is satisfied in the vicinity where animals and plants are located. Preferably, in the case of animals, it is desirable that the vicinity of the mouth and nose where breathing satisfies the above ion conditions!

[0081] Positive ions include ions that also have H + (H O) (m is an arbitrary natural number) force, and negative ions

Calcium has an extremely strong activity, which makes it possible to effectively remove and inactivate airborne bacterial ゃ virus gerogen components.

[0082] It is preferable that the animal and plant breeding facility of the present invention further includes an air blowing means for forming a flow of air in a certain direction in the breeding room. By further providing a blowing means, if air flows in a certain direction in the breeding room, the air in the breeding room can be prevented from flowing out of the breeding room. Although the direction of the air flow is not particularly limited, it is preferable that the air flow is directed to a surface such as a fence that cannot ventilate the outside of the breeding room such as the ground or a wall, instead of a surface that can ventilate the breeding room. .

[0083] In addition, the animal and plant breeding facility of the present invention preferably further includes suction means for sucking air in the breeding room in order to prevent air in the breeding room from flowing out. By additionally providing a suction means, it is possible to prevent the activated gas released into the breeding room from flowing out into the space outside the breeding room, and prevent the floating bacteria and the like in the room from flowing into the environment around the breeding room. At the same time, bacteria can be effectively removed from the rearing room.

[0084] It is more preferable that the animal and plant breeding facility of the present invention be provided with both the blowing means and the suction means. In this case, if the blowing means and the suction means are provided at opposing positions, an air flow from the blowing means to the suction means can be formed in the rearing room, and the air can be discharged to the outside by the suction means.

[0085] The animals and plants bred in a facility in an environment where the activated gas is released as described above can be treated with little effect from viruses, bacteria, floating bacteria, allergen components and odor components. Growing in an imaginative environment. Therefore, in the case of an animal used for appreciation in a zoo, an aquarium, or the like, an advantage such as a longer life can be obtained. In the case of economic animals for collecting food, eggs and milk at poultry farms, pig farms and ranches, there is also an advantage of improving the safety of such products. The present invention also provides animals and plants bred using the animal and plant breeding facility of the present invention.

[0086] The animal and plant breeding facility of the present invention is not limited to a large breeding facility, but can be applied to a small breeding facility for transporting animals. In this case, a portable power source such as a battery or a solar cell or a fuel cell can be used as a power source of the activation gas generating device, the blowing means and the suction means.

[0087] Further, the animal and plant breeding method of the present invention is characterized in that the animal and plant are bred in a breeding room by releasing an active gas that can eliminate airborne bacteria in the air into the animal and plant breeding room. Is what you do. The breeding method in the present specification refers to a method of breeding, producing, and raising organisms such as animals and plants. In this way, by releasing the activated gas into the animal and plant breeding room and breeding the animal and plant in the breeding room, it is possible to eliminate the suspended bacteria and the suspended bacteria in the breeding room space and prevent the growth of bacteria. be able to. Therefore, it is possible to maintain good hygiene conditions in the breeding room and to prevent infection of animals and plants with bacteria and bacteria. In addition, it is possible to prevent humans involved in the breeding facility's breeding operations, people who appreciate flora and fauna, and effects on the environment around the breeding facility. In addition, odor components can be positively decomposed to be decomposed.

[0088] In the above method, it is preferable to use positive ions and Z or negative ions or plasma as the active gas. By using these activated gasses, it is possible to positively remove viruses, power bacteria, floating bacteria, allergen components and odor components. Among them, the use of positive ions and Z or negative ions as the active gas is safer for the human body and can be taken as the most preferable method.

[0089] In addition, according to the above method, as a positive ion, H + (HO) (m is an arbitrary natural number)

2 m

Preferable ions are ions that also have O (H O) (n is an arbitrary natural number) force.

2 2 η

That's right. [0090] In the above method, the activation gas is not limited to this, but can be generated using a discharge or light irradiation type activation gas generator. .

[0091] In the above method, it is preferable to form a flow of air in a certain direction in the rearing room by using a blowing means. By forming airflow in a certain direction in the rearing room, it is possible to prevent the air in the rearing room from flowing out of the rearing room.

[0092] In the above method, it is preferable to prevent the air in the breeding room from flowing out by using a suction means for sucking the air in the breeding room. This can prevent the activated gas released into the breeding room from flowing into the space outside the breeding room, prevent the floating bacteria and the like in the room from flowing into the environment around the breeding room, and effectively prevent the breeding room from being released. Can be sterilized.

[0093] The animals and plants bred by the above breeding method grow with little influence from viruses, bacteria, suspension bacteria, allergen components and malodorous components. Therefore, in the case of an animal used for appreciation in a zoo, an aquarium, and the like, an advantage such as a longer life can be obtained. In the case of economic animals for collecting food, eggs, and milk at poultry farms, pig farms, and ranches, the benefits of improving the safety of such products can also be obtained. The present invention also provides animals and plants bred using the method for breeding animals and plants of the present invention.

[0094] Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. The present invention is not limited by the embodiments described below.

[0095] <First embodiment>

FIG. 1 is a diagram showing an outline of a breeding facility 1 according to a first embodiment of the present invention, FIG. 2 is a perspective view of an ion generating element 7, and FIG. FIG. 6 is a waveform diagram of a voltage. In the present embodiment, the case where it is used in the breeding facility 1 of the zoo will be described.

A force that is not limited to this may be used. As a flora and fauna, the powers shown here are when the lion 2 is nurtured, but are not limited to this. [0096] The breeding facility 1 of the example shown in Fig. 1 basically includes a breeding room 3 that forms a space for storing animals and plants, and an ion generator 4 that releases activated gas into the breeding room 3. Prepare. The breeding room 3 is surrounded by an iron or wooden fence 5, and a roof 6 is formed above the roof for safety and protection against wind and rain. The lion 2 lives in this breeding room 3. The structure of the breeding room 3 can be changed according to the type and characteristics of animals and plants, such as not forming the roof 6 which is not limited to the above-mentioned form.

In the example shown in FIG. 1, the ion generator 4 is composed of an ion generating element 7 for generating ions and blowing means 8 having 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 through the opening. Further, the ion generating element 7 is disposed closer to the breeding room 3 than the blowing means 8, and the blowing means 8 is set so as to blow air to the breeding room 3 via the ion generator 4. Therefore, when the ion generator 4 is operated, the ions can be diffused into the space in the breeding room 3 by the forced air blowing of the air blowing means 8. The ion generator 4 is provided near the center of the roof 6 of the breeding room 3. Therefore, the ions generated from the ion generator 4 can be released over the entire breeding room.

FIG. 2 is a schematic view showing a preferred example of the ion generating element 7. A dielectric 9 is provided on the surface of the ion generating element 7, a dielectric electrode 10 is provided on the back side of the dielectric 9, and an ion generating electrode 11 is provided on the surface of the dielectric 9 so as to face the dielectric electrode 10. Installed. In the example shown in FIG. 2, the shape of the ion generating electrode 11 is a net-like force. The force is not particularly limited, and a known needle shape or the like may be used. Furthermore, in order to generate ions more effectively, the shape of the electrode pattern, the shape of the edge, the material, and the like can be appropriately determined.

In the example of the ion generating element 7 shown in FIG. 2, the ion generating electrode 11 and the dielectric electrode 10 are connected to the high-voltage pulse driving circuit 13 through the lead wire 12. The high-voltage pulse drive circuit 13 is formed inside the ion generating element 7. In the ion generating device 4 having the ion generating element 7 having such a configuration, the ion generating device 4 is driven (that is, the peak value composed of the positive and negative voltages between the ion generating electrode 11 and the dielectric electrode 10 is, for example, 2.7 kV. A certain pulse By applying the voltage, the air sufficiently containing ions is released into the internal space of the breeding room 3 (active ion release space). Air containing sufficient ions contains, for example, both positive ions and negative ions, and when released into the active ion release space, it can eliminate airborne bacteria present in the active ion release space, or there are some! V, can deodorize the odor components and have an effective effect.

[0100] positive ions and respective ion concentrations position away 10cm from the generation point of the negative ions, by the 10, 000 / cm ³ or more, it is possible to obtain a high sterilizing effect. Further, when the I on concentrations of 300, 000 or ZCM ³ or more, no residual rate of airborne fungi in 1 hour after the release of ions can be 10% or less, it is carried out more quickly and efficiently sterilization it can. As an ion concentration measuring device, an air ion counter (Model No. 83-100B) manufactured by Dan Kagaku Co., Ltd. was used. For small ions with a mobility of lcm ² / V'sec or more, the ion generator 4 ion It is detected based on the relationship between the point of occurrence and the distance. This example is described in detail in JP-A-2002-95731.

FIG. 3 is a waveform diagram of a voltage used to drive ion generating element 7 shown in FIG. When discharging discharge gas with a high concentration of positive and negative ions into the space to remove and inactivate mold virus, allergens, and airborne bacteria among the discharge gas, a high-frequency AC pulse voltage as shown in Fig. 3 is generated. It is preferably used. In the example shown in Fig. 3, a pulse voltage on a sine wave that gradually decays is applied for T seconds, and then a pause time of T seconds is applied.

Set and repeat this cycle. The condition of the pulse voltage in the normal mode of the ion generator 4 is that the frequency of the sine wave is 20 kHz and the pulse repetition cycle is 60 Hz. Also, T is 1 ms, T is about 15.7 ms (1000Z60 1),

The 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 generation of ozone.

[0102] This discharge generates positive ions and negative ions from the ion generation electrode 11. H + (HO) (n is an arbitrary natural number) is generated as positive ion, and O (HO) (n

It has been confirmed by precise measurement by mass spectrometry that 2 η 2 2 η is the most stable generation of any natural number). A chemical reaction occurs when these positive and negative ions are generated simultaneously in the air. To produce active species, hydrogen peroxide HO or hydroxy radical OH. these

Removes and inactivates airborne bacteria and viruses and allergen components.

[0103] The activated gas containing the released ions removes viruses, viable bacteria, floating bacteria, allergen components and malodorous components present in the space inside the breeding facility 1. 2 can be prevented from being adversely affected. Here, the adverse effects refer to infections caused by viruses, virulent bacteria, allergen components and airborne bacteria, or the unpleasant smell of lion 2 which makes it unpleasant.

FIG. 1 shows a state in which a human 14 who is visiting the lion 2 (or is breeding the lion 2) exists around the fence 5. In this example, the air passes freely through the fence 5 between the inside of the breeding room 3 and the outside where there is a human 14 who comes to visit and raises. Become. Therefore, in an environment where the breeding room 3 is installed outdoors and the wind is strong, if the activating gas is released into the internal space where the lion 2 is present (when the ion generator 4 is used, Is spread to the outside space where there are humans 14 who are visiting (breeding). As a result, the components of the activated gas reach the person 14 who is visiting (breeding), but the activated gas containing ions has no effect on the human body. Testing laboratories have confirmed that the ions are safe.

[0105] Further, the present embodiment is applicable not only to a large breeding facility but also to a small breeding facility for transporting animals, in which case the power of the ion generator and the blowing means is reduced. As a source, it is appropriate to use a portable power source such as a battery or a solar cell or a fuel cell.

[0106] <Second embodiment>

FIG. 4 is a diagram showing an outline of a breeding facility 21 according to the second embodiment of the present invention. As shown in FIG. 4, in the present embodiment, the active gas discharged into the breeding room 23 does not reach the environment where humans 31 exist around the breeding facility 21. . That is, a flow is created in the air in the breeding room 23 of the breeding facility 21 so that the activated gas component is not scattered outside the breeding room 23, and is released in a certain direction. Figure 4 In the example shown, a plurality of air blowing means (second air blowing means 29) are provided on the roof 26 of the breeding room 23 so that the air flows in a certain direction. Further, a suction means 30 is provided on the floor of the breeding room 23 (the surface facing the second blowing means 29). Other basic configurations are the same as those in the first embodiment.

That is, in the example shown in FIG. 4, a plurality of propellers are provided on the roof 26 separately from the first blowing means 28 (corresponding to the blowing means 8 in the example shown in FIG. 1) of the ion generator 24. A second blowing means 29 provided with a second air blower is provided. An opening (not shown) is formed in the roof 26, and a second air blowing means 29 is provided to face the opening. The second blowing means 29 are provided at the four corners of the roof, and can form an airflow from the roof side to the ground side over almost the entire area of the rearing room 23. It should be noted that the second air blowing means 29 is not limited to the above-mentioned installation positions and installation quantities.

Further, on the ground side (the floor of the breeding room 23), a suction unit 30 having a plurality of propellers is provided at a position facing the second blowing unit 29. When the suction means 30 is installed at a position facing the second air blowing means 29, the air from the second air blowing means 29 flows straight into the suction means 30. The turbulence of the flow may occur, but is not limited to this. The suction means 30 is connected to a duct, and the other end of the suction means is configured to communicate with a space separated from the breeding facility 21 or an air cleaning device or the like.

[0109] The number of the second air blowing means 29 and the number of the suction means 30 may not be plural as long as air can flow in a fixed direction in the internal space of the breeding facility 21. For example, it is also possible to install a second blowing means 29 and one suction means 30 having a size equal to the area of the roof 26. Further, in the present embodiment, the direction of the flow of air from the roof 26 side to the ground side is not particularly limited, and the second air blowing means 29 is provided on the ground side which is not particularly limited. It is also possible to adopt a method in which suction means 30 is provided on the side and air flows from the ground side to the roof 26 side.

[0110] FIG. 4 shows a state in which a human 31 who is visiting (or breeding) a heron bred in the breeding room 3 is present around the fence 25. In the above configuration, when the second air blowing means 29 and the suction means 30 are operated, the second air blowing means 29 causes the roof 26 to be closed. Then, an airflow in a certain direction is formed toward the ground. Therefore, the air in the breeding room 23 leaks out of the breeding room 23 through the fence 25. Further, the air blown by the second blowing means 29 is sucked by the suction means 30 and discharged to the outside through a duct (not shown) connected to the suction means 30. Therefore, compared to the case where only the second blowing means 29 is provided, the air in the breeding room 23 further leaks out around the breeding room 23, so that the activated gas and the floating Bacteria do not leak around the rearing room 23. As described above, according to the second embodiment of the present invention shown in FIG. 4, the activated gas that can only prevent harm to the human 31 due to floating bacteria and the like reaches the environment where the human 31 exists. It can be used more effectively because it is released only into the space where the unraveled animals and plants are located. This is a major difference from the first embodiment.

[0111] In the present embodiment, a plurality of second air blowing means 29 and a plurality of suction means 30 are provided to form a constant air flow in the breeding room 23, so that the air in the breeding room 23 is Although the configuration to prevent the air from being released to the outside has been illustrated, the air flow to the side of the breeding room 23 is provided by providing a blowing means that blows air from above to below the entire upper side of the breeding room 23. It is good also as a structure which forms an air curtain which used this. The air curtain blocks the room from the outside and prevents the air inside the breeding room from leaking to the outside.

In the present embodiment, a control unit (not shown) for controlling the air volume of the second air blowing unit 29 and the suction unit 30 can be provided. The control unit is configured to simultaneously or individually increase or decrease the amount of air blown by the second blowing means 29 and the suction means 30 in conjunction with an instruction input from another switch and an output signal of Z or sensor force. Can also be configured. With such a configuration, it is possible to simultaneously or individually increase or decrease the amount of air blown by the second blowing means 29 and the suction means 30, and to adjust the sterilization performance to a desired level. When the air is less likely to leak from the breeding room to the surroundings outside the breeding room, an effect can be obtained.

[0113] In addition to the above configuration, a control unit (not shown) connected to the second blowing unit 29 and the suction unit 30, a temperature sensor (not shown) connected to the control unit, and A switch (not shown) may be provided in the breeding room 23. The control unit includes, for example, a CPU, a ROM, a RAM, and the like. [0114] In such a configuration, when the temperature sensor detects the temperature, the output signal is input to the control unit. If the control unit determines that the detected temperature is within the range of the preset optimum temperature of the virus, bacterium, floating bacteria, allergen component, etc., the second blowing means 29 and The amount of air blown by the suction means 30 is simultaneously increased, and when it is determined that the temperature is outside the optimum temperature range, the amount of air blown by the second air blow means 29 and the suction means 30 is simultaneously reduced. It is to be noted that, when the temperature is within a temperature range at which the animal's immunity is reduced, the air flow rate may be reduced, and when the temperature is outside the range, the air flow rate may be increased!

[0115] Further, in the present invention, in addition to the temperature sensor, a sensor capable of detecting the generation state of bacteria, such as a humidity sensor, an object sensor, or a biological sensor, may be used alone or in combination.

[0116] Further, the switch can input ONZOFF of the second blowing means 29 and the suction means 30, the timer function thereof, the strength of the blowing amount, 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 30 for 30 minutes, and after the lapse of 30 minutes, the suction means 30 and the second And the air blowing means 29 can be operated. In such a configuration, it is not necessary to release the activated gas during cleaning of the breeding room. Therefore, the second blowing means 29 is stopped for a certain period of time (30 minutes) to activate the activated gas. Gas blowing can be stopped. At this time, since the suction means 30 is operating, the air in the room can be discharged to the outside of the room. Then, after the work is completed, both the second blowing means 29 and the suction means 30 are operated to discharge the activation gas and exhaust the room air. Thus, it is possible to effectively remove bacteria and exchange air.

[0117] The present embodiment is not limited to a large breeding facility, but can be applied to a small breeding facility for transporting animals. In this case, an ion generator, a blowing means, and a suction means are used. It is appropriate to use a portable power source such as a battery, a solar cell, or a fuel cell as the power source for the battery.

FIG. 5 is a diagram showing an outline of a breeding facility 41 according to the third embodiment of the present invention. As shown in FIG. 5, this embodiment shows an example of a poultry farm where chickens 42 are bred as an example of animals and plants. In this figure, chicken 42 eats feed without drawing the whole breeding. Only the area that The breeding room 43 of the breeding facility 41 in the present embodiment is separated by a fence 45 so that the chickens 42 enter each bird so that each chicken 42 can eat the feed given to each. A feed bin is provided at the front, and an egg bin 49 for storing eggs laid by chickens 42 is provided. Other basic configurations are the same as in the first embodiment.

[0119] Also in the poultry farm of the present embodiment, the ion generator 44 is provided on the roof 46 of the breeding room 43. When the ion generator 44 is operated (that is, the ion generating element 47 and the blowing means 48 are operated), viruses and viable bacteria, floating bacteria, and allergen components existing in the internal space of the breeding room 43 are removed. The chicken 42 in the breeding room 43 is exposed to the risk of being infected by bacteria, viruses, allergens, etc., because the positive ions and negative ions generated from the ion generator 44 are released to the chickens 42 in the breeding room 43. It can be avoided and is very effective.

[0120] Further, the ions as the activation gas in the present invention are also released not only in the chicken 42 but also in the eggs laid by the chicken 42. Therefore, mold and the like do not adhere to the chicken egg surface, and damage from bacteria, viruses and allergen components can be prevented. Therefore, if the eggs are used as food, the risk of affecting those who eat the eggs is greatly reduced.

FIG. 6 is a diagram showing an outline of a breeding facility according to the fourth embodiment of the present invention. As shown in FIG. 6, this embodiment shows an example of a breeding facility that breeds birds for viewing. The major difference from the first embodiment is that, for example, humans observing (or breeding) the birds 52 that are not limited to the internal space of the breeding room 53 in which the birds 52 are bred as animals. Is that the active gas is also released into the external space where the gas exists. Other basic configurations are the same as those in the first embodiment.

[0122] Specifically, the breeding facility 51 according to the present embodiment includes a breeding room 53 for accommodating the ornamental birds 52 so as not to escape, a structure 60 surrounding the breeding room 53, and a roof 56 of the structure 60. And an ion generator 54 provided in the main unit. The ion generator 54 has an ion generator 57 and a blowing means 58 similar to the ion generating element 7 and the blowing means 8 in the ion generating apparatus 4 of the example shown in FIG. 1, and is formed on the roof 56 of the structure 60. Opening ( (Not shown), and is configured to flow ions into the structure 60 through the opening. The ion generator 54 is provided near the center of the roof 56 of the structure 60. Therefore, the ions generated from the ion generator 54 can be emitted over the entire area of the structure 60.

[0123] The material and form of the structure 60 are not particularly limited, and examples thereof include metal, wood, reinforced concrete, resin, and glass. Since the breeding room 53 is inside the structure 60, the breeding facility 51 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 59 who is visiting (breeding) a bird 52 is present around a breeding room 53 in the structure 60. When the ions are released from the ion generator 54, viruses and viable bacteria ゃ allergen components and floating bacteria in the space within the structure 60 including the breeding room 53 are removed and inactivated, so that the bird for viewing 52 Or, it can prevent humans 59 who are visiting (bringing) to see it.

As described above, according to the present embodiment, the birds for viewing 52 and the ions generated by the ion generator 54 are first intentionally come to visit (the animals are bred). ) It differs from the first embodiment in that it is configured to be able to release to both human 59.

FIG. 7 is a diagram showing an outline of a breeding facility 61 according to the fifth embodiment of the present invention. As shown in FIG. 7, the present embodiment shows an example of a breeding facility 61 for breeding birds for appreciation. FIG. 7 shows a case where aquatic animals 62 such as fish and amphibians are bred as examples of animals. Aquatic animals 62 such as fish and amphibians are present in the aquarium (breeding room 63). In order to breed the aquatic animals 62, the aquarium (breeding room 63) is made up of plate materials 65 rather than fences, and is sealed so that the water inside does not leak. In addition, as long as the aquatic animals do not fly in the air, the roof 66 of the breeding room 63 may or may not be installed. Other basic configurations are the same as those in the first embodiment.

In the present embodiment, as shown in FIG. 7, an ion generating device having an ion generating element 67 and a blowing means 68 similar to the ion generating element 7 and the blowing means 8 of the example shown in FIG. The device 64 is installed on a plate-like fixing jig 69 provided so as to cover a part of the upper surface of the aquarium (breeding room 63). In order to diffuse ions throughout the water tank (breeding room 63), the ion generator 64 is preferably provided near the center of the upper surface of the water tank (breeding room 63). When the ion generator 64 is operated, the ions serving as the activation gas are released to a water-free region (overwater region) A in the water tank (breeding room 63). No ions penetrate into the area B containing water (the underwater area). The ions are distributed throughout the water area A, which is an area in the atmosphere.

[0128] When the ion generator 64 is activated, the ions as the activated gas are released to the water area A in the aquarium (breeding room 63), and the virus, the power bacteria, the floating bacteria, the allergen component, and the offensive odor are released. The components are removed 'inactivated and the water area is cleaned.

[0129] Although aquatic animals such as fish and amphibians may appear in the above-water area A for the purpose of breathing or eating food that does not completely exist in the underwater area B. Therefore, in consideration of such a situation, by using the ion generator 64 to release the ions as active gas into the water region A, an effective action can be exerted on aquatic animals such as fish and amphibians. be able to.

FIG. 8 is a diagram schematically showing a preferred example of an ion generator 71 as a sixth embodiment of the present invention. The ion generator 71 shown in FIG. 8 is an ion generator applicable to the breeding facility of the present invention described above. In the present ion generator 71, a blowing section having a blowing path and a blowing means power and an ion generating means are united and attached to an opening provided on a wall surface of the breeding room 72, whereby ions are generated by the ion generating means. The function of releasing the air and blowing the ions into the room by the air blower and exhausting the air inside the breeding room to the outside of the breeding room 72 can be realized by one device. For this reason, construction becomes easy, and low cost dangling can be realized.

[0131] Specifically, as shown in Fig. 8, two ducts 73 and 74, which are ventilation paths, are provided to penetrate the flat mounting plate 75. The mounting plate 75 is fixed with screws or the like so as to cover the opening of the wall of the breeding room 72 so that one surface of the mounting plate 75 is inside the breeding room 72 and the other surface is outside the breeding room 3. As a result, one end of both ducts 73 and 74 is located inside the rearing room 72, The other end is arranged so as to be located outside the breeding room 72, and both ducts 73 and 74 are in a state of communicating with the outside of the breeding room. Fans 76 and 77 are provided in both ducts 73 and 74 as blowing means, respectively, and the directions of the blowing are set to be opposite to each other. That is, one duct 73 is an air intake duct for blowing air outside the breeding room to the nursery room, and the other duct 74 is an exhaust duct for exhausting air inside the breeding room to the outside of the nursery room.

[0132] Further, the air intake duct 73 is provided with an ion generating element 78, which is an ion generating means, closer to the rear of the breeding room than the fan 76, and the breeding room 72 is fed into the breeding room 72 together with the externally introduced air. It is blown.

[0133] The mounting plate 75 is provided with a control unit 79 connected to the fans 76, 77 to control the operations of the fans 76, 77. are doing. The control unit 79 includes a CPU, a ROM, a RAM, and the like. Further, the control unit 79 is connected to the switch 80 and the temperature sensor 81, and has a function of simultaneously or individually increasing or decreasing the amount of air blown by the fans 76 and 77 according to the signal. The temperature sensor is provided in the breeding room 72 and detects the temperature in the breeding room 72. The temperature sensor should be attached to the rear side of the breeding room.

In such a configuration, when the temperature sensor 81 detects a temperature, a detection signal is input to the control unit 79. If the control unit 79 determines that the detected temperature is within the range of the optimum temperature of the virus, bacterium, floating bacteria, allergen component, etc. set in advance, the blowing unit 82 and the suction unit 83, the air blowing amount is increased, and when it is determined that the temperature is out of the optimum temperature range, the air blowing amounts of the air blowing means 82 and the suction means 83 are reduced. In addition, when the immunity of the animal is within the temperature range where the immunity decreases, the amount of air blow may be reduced, and when the temperature is outside the range, the amount of air blow may be increased.

[0135] In the above-described embodiment, a sensor that can detect the occurrence state of bacteria, such as a force sensor exemplified as a temperature sensor, a humidity sensor, an object sensor, or a biological sensor, is used alone or in combination. Is also good.

[0136] The switch 80 can input the ONZOFF of the fans 76 and 77, the timer function thereof, and the strength of the air flow. For example, as a timer function, if the user inputs and sets a desired time (for example, 30 minutes), the control unit 79 operates only the fan 77 on the exhaust duct 74 side for 30 minutes. After the elapse of 30 minutes, the fan 77 and the fan 76 on the intake duct 73 side can be operated. With such a configuration, it is not necessary to release the activated gas during cleaning of the room such as the breeding room. Therefore, the fan 76 on the intake duct 73 side is stopped for a certain time (30 minutes) to activate the air. It is possible to stop the ventilation of the gas. At this time, since the fan 77 on the exhaust duct 74 side is operating, the air in the room can be discharged outside the room. Then, after the work is completed, both fans 76 and 77 can be operated to discharge the activated gas and exhaust the indoor air. In this way, it is possible to effectively remove bacteria and exchange air.

[0137] With such a configuration, in conjunction with the switch 80 and the sensor 81, the release amount of the activated air is changed, and the activated air is discharged into the target space at high speed and in large quantities; Since it is possible to minimize the amount of air leaking from the target space, it is possible to carry out the optimal sterilization suitable for breeding.

[0138] The number of intake ducts 73 and the number of exhaust ducts 74 need not be one, and a plurality of each may be provided. It is desirable that the total airflow of each of the intake duct 73 and the exhaust duct 74 is almost the same, but, for example, the ratio of the intake air to the exhaust air is within a ratio of 1: 2 or 2: 1. In such a case, effects such as virus inactivation can be sufficiently obtained. Further, in FIG. 8, the ducts and fans of the intake duct 73 and the exhaust duct 74 have similar shapes, and may have different shapes if necessary.

Further, although the length of the intake duct 73 or the exhaust duct 74 is short in FIG. 8, it may be extended to an appropriate place. Further, a filter may be provided in the intake duct 73 or the exhaust duct 74 or connected to an air purifier. Since the movement and diffusion of dust and germs can be prevented, the device can be operated more safely. Still further, a structure may be adopted in which heat exchange is provided integrally, has a temperature or humidity control function, and stabilizes the indoor environment. In addition, the intake duct 73 and the exhaust duct 74 are partially combined to ensure the room temperature, etc., which does not need to be completely separate systems, and to secure the concentration of the activated gas. It may be structured.

[0140] In the above embodiment, as in the 1S fourth embodiment in which the ion generator 71 is provided on the wall surface of the breeding room 72, the activated gas is released into the structure surrounding the breeding room. In the case where the ions are emitted, the present ion generator 71 may be provided on the wall surface of the structure, for example.

[0141] Further, the ion generator 71 of the present embodiment can be used in animal and plant breeding facilities to obtain an effect. The effect of the present device is not limited to this. The ion generator 71 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 the present ion generator 71 is attached to the wall 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. Then, the air in the facility space can be exhausted by the exhaust means. When used in such a space, it becomes possible to suppress the diffusion of pathogens, viruses, and other contaminants from the target space to another space at low cost.

[0142] Hereinafter, the present invention will be described in more detail with reference to Experimental Examples, but the present invention is not limited thereto.

A system as shown in FIG. 9 was prepared in order to carry out an experiment on the concentration of an activated gas capable of inactivating viruses. As shown in FIG. 9, in this experimental example, a sealed box 91 of lm ³ was used as an example of the space corresponding to the breeding room, and in this box 91, the ion generating element 93 and the blower having the propeller force were also provided. An ion generator 92 including means 94 is provided, and positive ions and negative ions emitted from the ion generating element 93 are diffused in the box 91. A virus is sprayed on the box 91 by the sprayer 95 to spread the virus in the box 91, and the virus in the space in the box 91 is collected at regular intervals by the collector 96, thereby inactivating the virus. Was confirmed. Note that, similarly to the ion generator 4 in the above-described first embodiment of the present invention, the ion generator 92 applies H + (HO) (m Is an arbitrary natural number) and O-(HO) (n is any

2 m 2 2 n

(Natural number) is designed to emit a strong negative ion.

[0144] Sprayer 95 sprays liquefied feline coronavirus (FIPV: 79-1146 strain) into box 91. Coronavirus is a pathogenic virus known to infect livestock. It is said to cause respiratory illness, hepatitis and enteritis. It is also said to cause upper respiratory inflammation in humans.

[0145] A test was performed to determine TCID (the amount of virus that infects 50% of the cultured cells) by cell culture (cat kidney cell: fcwf4 p86 strain) using the virus solution collected by the collector 96.

50

The infectivity of the virus was examined. The lower the infectivity of the virus, the more inactivated the virus.

[0146] In this experimental example, a case that caused the ions as Example (2 conditions ion concentration inside space of the box 91 is positive and negative ions are about 150 ZCM ^3, and the 7,000 ZCM ^3), compared As an example, when no ions are generated (the ion concentration in the internal space of the box 91 is about 50 ions each for positive and negative ions, Zcm ³ ), the test is performed under a total of three conditions, and the effect of ions in the internal space of the box 91 The effect of time on the TCID of the virus was examined. In addition,

50

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 No. 83-1001B) manufactured by Dan Kagaku Co., Ltd. was used as the measuring device. The positive and negative ion concentrations in the space are adjusted by intermittently driving the power supply of the ion generator 92.

[0147] The experimental results are as follows. FIG. 10 is a graph showing the time dependence of TCID at a spatial average ion concentration of 150 Zcm ³ for each positive and negative ion. According to Figure 10

50

It can be seen that the infectivity of the virus solution collected during the ion treatment time of 40 minutes to 50 minutes was reduced by 98.8% compared to the case where the ion generator 92 was not operated. It has been found that this ion concentration can sufficiently inactivate the virus. In the drawing, "no ion" means that the ion generator 92 is not operated, and "ion exists" means that the ion generator 92 is operated.

FIG. 11 is a graph showing the time dependency of TCID when the spatial average ion concentration of each of the positive and negative ions is 7,000 Zcm ³ . According to Figure 11, the ion treatment time is 30-40

50

The infectivity of the virus solution collected in 10 minutes was reduced by 99.7% compared to the case where the ion generator 92 was not operated. It was a component of this concentration that the virus could be sufficiently inactivated.

[0149] From the above, the air average ion concentration of each positive and negative ions at least 150 ZCM ³ exist U, prefer to be there. If the amount is less than that, there is a possibility that the virus cannot be sufficiently inactivated.

As described above, at least 150 positive ions and negative ions of at least 150 Zcm ³ are each released by the ion generator 92, so that the infectivity of viruses floating in the space can be greatly reduced. In this experimental example, a dedicated device called a virus sprayer 95 and a virus collector 96 was used. However, when animals infected with the virus and animals infected with the virus were bred simultaneously in the breeding room, virus It has the effect of reducing the probability of virus infection due to the release of virus from infected animals to non-infected animals. In such a case, by setting the concentration of at least positive ions and negative ions to 150 Zcm ³ , an excellent effect of suppressing disease infection in the breeding room can be exhibited.

[0151] Regarding the setting conditions of the ion concentration that can be expected to suppress the disease infection as described above, a certain effect can be obtained if it is realized in some places in the animal and plant breeding environment. However, it is desirable that the ion concentration is realized at a place where animals and plants are arranged. Furthermore, it can be expected that disease infection can be effectively suppressed by satisfying the ion concentration condition at the position of the respiratory organ (ie, mouth or nose) of the bred animal.

[0152] In the above experimental example, the effect of the present invention showing an example using a suspended cat coronavirus was confirmed to be effective also for influenza virus, and is not limited to feline coronavirus. Similar effects can be exerted on other pathogenic substances or bacteria such as unknown viruses.

[0153] <Experimental example 2>

Rats 102 (10 males and 10 females) were bred in a nursing facility as an animal, and a system shown in Fig. 12 was prepared in order to verify the effectiveness of the activated gas on rat growth. The breeding facility 101 shown in FIG. 12 can of course be used for breeding animals and plants. The breeding facility 101 is particularly suitable for breeding facilities for animals, such as experimental animals such as rats and mice, from which virus infection should be completely eliminated.

[0154] The breeding facility 101 includes a box-shaped breeding room 103 in which animals and plants are housed, an air introduction duct 104 and an air exhaust duct 105 connected to an opening formed in the breeding room 103, and a breeding room 103. A breeding basket 106 for fractionation and accommodation for each individual or a plurality of individuals, a blast from the air introduction duct 104, a bulky wind tunnel 107 for collecting animals and plants in the breeding cage 106, and the wind And an ion generating element 108 provided at the tip of the cavity 107.

[0155] The breeding room 103 preferably has a sealable structure such as a glass plate in order to completely shut out infections such as viruses. The breeding basket 106 is made of, but not limited to, a net-like metal material.

[0156] On the side of the breeding room 103, an openable / closable window 109 is formed so that the breeder 110 can care for rats such as feeding and water supply. It is most preferable that the opening / closing window 109 has a function of blocking the flow of air between the inside and the outside of the breeding room 103.However, in order to facilitate feeding, etc., a part of air such as a grid or a net is not provided. A part that can diffuse may be provided. Even in that case, as will be described later, since a forced air flow is formed from the air introduction duct 104 to the air exhaust duct 105, the air passes through the inside and outside of the breeding room 103 through the opening / closing window 109. It is possible to control and reduce the infection such as virus.

[0157] The installation locations at the ends of the air introduction duct 104 and the air exhaust duct 105 opposite to the side connected to the breeding room 103 are to introduce air from outside the breeding room 103 and to install the air outside the breeding room 103, respectively. It is not particularly limited as long as the air can be exhausted to the outside, but it is preferable to communicate with an air purifier capable of removing viruses in order to prevent infection of animals and plants in the breeding room 103 with viruses and the like. . The air introduction duct 104 and the air exhaust duct 105 need to be provided with a blowing means in order to form an airflow in which the force on the air introduction duct 104 also flows toward the air exhaust duct 105. It is desirable to provide it in

According to the above configuration, the air outside the breeding room 103 is sucked in from the air introduction duct 104 by the blowing means, and the air passes through the wind tunnel 107 and enters the breeding basket 106 together with the ions generated by the ion generating element 108. And finally discharged out of the rearing room 3 through the air exhaust duct 105.

[0159] As described above, since the airflow inside the breeding room 103 is provided with the air supply / exhaust facility so that air flows from the air introduction duct 104 to the air exhaust duct 105, the opening / closing window 10 is provided. 9 reduces the exchange of air between the inside and outside of the breeding room 103, and can prevent viruses and the like from reaching the rat 102 and the human without being inactivated by each other. It is possible to reduce the possibility of mutual disease transmission between rats.

The following experiment was performed using the breeding facility 101 having the above configuration. In this experiment, clean air equivalent to 15 ventilations / hour is blown into the breeding room 103 from the air introduction duct 104 and discharged from the air exhaust duct 105. Air containing positive and negative ions is supplied from the ion generating element 108 and supplied to the living area of the rat 102 to reduce the concentration of viruses and the like released from the rat 102. By this effect, when a part of the rat 102 becomes a specific disease and releases a pathogenic virus to the surroundings, the new disease of the healthy rat 102 is suppressed, and the healthy life of the whole rat 102 is improved, The service life can be expected to be prolonged.

[0161] In this experimental example, ions were released using the same ion generating element 108 as that described in the first embodiment, and the positive and negative ion concentrations in the breeding cage 106 were reduced to 20,000 those with ZCM ³ or 3, 000 pieces / cm ^3, no ion release (positive and negative ion concentration of about 50 ZCM ³⁾ in three conditions, were kept in conditions completely isolated from each other. The conditions other than ion generation are the same, including air blowing. In addition, it was confirmed that the ozone concentration in the breeding room 103 was less than O.Olppm.

In this experimental example, the growth state of rat 102 under the above three conditions was examined using healthy rat 102 (8 weeks old). Figure 13 shows the average change in body weight for males and females under each condition. Fig. 13 shows the results for female and Fig. 14 shows the results for female.

[0163] According to this, the change in body weight of each male and female was strong without any significant difference due to the three ion conditions described above. In general observations (eye condition, urine condition, food consumption), no abnormalities were observed in all males and females in all cases, and as a result, it was confirmed that the rats were kept under good breeding conditions .

[0164] Therefore, since the bred rat 102 was healthy, there was no change that could affect health depending on the presence or absence of ions, confirming that the safe use of ions under these conditions was possible. Was done. In addition, by driving the ion generator of the present invention, when a part of the rat 102 or a caring person becomes ill with an air-borne disease, pathogenic viruses and the like contained in the air around the rat 102 are inactivated. It becomes possible to do a rat 102 or rat It is expected to be effective in suppressing human disease infection and maintaining good health.
