Description

  The present invention relates to a highly airtight box, for example, a waste container such as garbage or a diaper, a toilet and a toilet tank, a container with a highly airtight refrigeration / refrigeration device and a vehicle with a refrigeration / refrigeration device, a refrigerator, an indoor / inside vehicle The present invention relates to an apparatus that is mounted on an air conditioner or the like for the purpose of regular sterilization and deodorization.

  With the aging society, demand for diapers and other filth containers is increasing in proportion to the population requiring care, but because it emits a foul odor each time it opens, there is a burden and discomfort on the caregiver and the surroundings. It is unsanitary. Each household also has a garbage storage box, but every time it is opened, it emits a foul odor due to the growth of various bacteria, which places a heavy burden on housewives and is unsanitary. In addition, overseas / domestic refrigeration and refrigerated goods are mainly transported by transport containers and trucks, and there are many containers and trucks with air conditioners. Odor is a problem. Furthermore, refrigerators, indoors, and vehicle air conditioners also suffer from odors due to stored materials and usage conditions.

  Here, a bactericidal deodorant has been proposed as a solution to the above problem. However, when used in a trash bin or a garbage storage box, the present situation is that a bad odor is emitted when the container is opened. In addition, when used in an air conditioner (for example, spraying and circulation sterilization methods), there are problems such as an unpleasant odor or mold odor that cannot be cleaned even if the inside of the air conditioner is cleaned, and odors moving to the next cargo. . Furthermore, as another solution, a method has been proposed in which air is sucked from a space to be sterilized and deodorized, and contaminants are adsorbed or removed by a filter. However, maintenance such as replacement of the filter is indispensable due to long-term use, and satisfactory performance may not be obtained because the performance of the filter is not sufficient.

  By the way, in recent years, air cleaners and air conditioners that generate negative ions and ozone are widely used for indoor air cleaning and refreshing. Many techniques have been proposed for deodorizing the target space using a negative ion / ozone generator that simultaneously generates negative ions and ozone having a deodorizing effect.

  First, the negative ion / ozone generator according to Patent Document 1 is an apparatus that is assumed to be attached to the ceiling of a room, and is characterized in that the positive electrode is disposed below the negative electrode. According to this, a downward airflow containing negative ions and ozone can be generated without using a fan or a motor.

  Next, the negative ion / ozone generator according to Patent Document 2 includes a negative electrode having a needle-like tip and a cylindrical ground electrode arranged concentrically in parallel to the negative electrode, and the negative electrode and the ground electrode are relatively disposed. The negative electrode or ozone is generated by adjusting the distance between the tip of the negative electrode and the end face of the ground electrode by applying a high voltage to the negative electrode.

  Next, the negative ion / ozone generator according to Patent Document 3 is a device that generates ozone and negative ions by applying a DC high voltage between the needle electrode and the ground electrode to cause corona discharge at the tip of the needle electrode. is there.

Next, the negative ion / ozone generator according to Patent Document 4 has a positive electrode made of a metal plate provided with one or a plurality of holes having a raised portion around the periphery, and the tip of the negative electrode is the positive electrode. It is located in the vicinity of the hole. With this configuration, a sufficient air flow is generated by the discharge, so that the generated negative ions and ozone can be diffused without using a separate fan such as a fan or a motor.

  Thus, as shown in Patent Documents 1 to 4, there are many negative ion / ozone generators that simultaneously generate negative ions and ozone. By the way, in the negative ion / ozone generator according to Patent Documents 1 to 4, in order to send the generated negative ions and the air containing ozone to the space to be treated, the generator is placed on the ceiling so that its own weight (ozone is less than air). A method is adopted in which the material is naturally dropped (for example, Patent Document 1), blown by a fan or the like (Patent Document 3 or the like), or a wind generated when negative ions are generated (Patent Document 4). . However, when air containing negative ions and ozone is sent to the target space by such a method, there is a problem that the generated ions adhere to the surroundings or stay in the apparatus and do not diffuse efficiently into the target space. .

Therefore, in order to solve this problem, Patent Document 5 discloses that a negative ion generator is provided with a heat source so that negative ions and ozone are efficiently diffused into the atmosphere, thereby causing convection by heat to generate indoor and atmospheric air. Means for diffusing into it have been proposed.
JP2007-141837

  However, it is assumed that the negative ion / ozone generators according to Patent Documents 1 to 5 described above are installed inside a room. Therefore, it is not suitable for use in a closed box where there is a lot of garbage and filth. Here are the reasons. The first reason is that the processing air generated from the negative ion / ozone generator is so weak that the processing air does not reach the back of the sealed box, which should be treated. Is mentioned. When there are many garbage and filth as described above, the concentration of the anomalous odor components and the amount of anaerobic bacteria that cause the generation of odorous components are higher in the back where the air permeability is poorer than the upper part that touches the outside air. Therefore, even though it is originally to be processed in the back of the sealed box, the wind speed of the processing air is too low so that the processing air does not reach every corner of the sealed box. If this situation is left unattended, not only bad odor but also flammable gas such as methane gas may be generated in large quantities, which is very dangerous. Next, it is assumed that the negative ion / ozone generators according to Patent Documents 1 to 5 are arranged and used in a room that is a processing target space. Therefore, also when using it for the above-mentioned closed box, the said generator is arrange | positioned and used in the said closed box. However, as described above, when the generating device is placed in a closed box where a lot of garbage and filth are present, sparks from high voltage application circuits and fans existing in the device are present in the methane There is a risk of ignition by flammable gases. This is the second reason why the negative ion / ozone generators according to Patent Documents 1 to 5 are not suitable for the treatment of the sealed space.

By the way, the negative ion / ozone generator according to Patent Document 6 has a configuration that can be solved when the above-described problems of the devices according to Patent Documents 1 to 5 are observed. Specifically, Patent Document 6 discloses an ozone generator, an ozone air pump that sends out generated ozone to the outside, a negative ion generator that uses tourmaline, and a negative ion that sends out the generated negative ions to the outside. Providing a negative ion / ozone generator that can deliver ozone and negative ions by connecting a hose sent from the ozone generator and negative ion generator with a Y-shaped tube Has been. In this way, by sending out processing air containing negative ions and ozone generated using an air pump and introducing the processing air into a sealed box using a hose, the above two problems are Can be resolved.

  However, although this inventor tried the form which separately generate | occur | produces ozone and negative ion of patent document 6, and mixed, it confirmed that a target space cannot be deodorized and disinfected effectively. The reason is estimated as follows. Many offensive odors and chemical substances are positive ions and have a positive charge. Here, the odor is considered to be generated when a part of the odor molecule vibrates, and the odor can be suppressed by suppressing the vibration. Then, the negative ions give electrons to the vibration part of the odorous molecule, so that it becomes electrically neutral and the vibration is settled and deodorized. Therefore, negative ions are effective for deodorization, but negative ions are very unstable, and soon after they are generated, they combine with positive ions present in the system, combine with other substances, and decompose. Or change to other substances. Therefore, in the apparatus of Patent Document 6, it is considered that most negative ions have disappeared. Similarly, with respect to ozone, it is known that the reaction of changing from ozone to oxygen becomes faster as the temperature and pressure rise. Therefore, in the apparatus of Patent Document 6, it is considered that there is a high possibility that much of ozone is decomposed before reaching the target space. Thus, in the apparatus according to Patent Document 6, air having a low content of ozone and negative ions is applied to the target space through the tube. In this case, in addition to the small amounts of ozone and negative ions, which are both active ingredients, ozone, which is one of the active ingredients, has no charge per se. Therefore, in addition to the fact that both active ingredients are small, the frequency of binding with malodorous and chemical components is low, and for electrically neutral ozone molecules, there is no electrical attraction between the charged malodorous components. It is considered that the collision frequency with the malodorous component is further reduced. Therefore, an object of the present invention is to provide means capable of performing deodorization and sterilization in every corner of the space safely and reliably even when applied to a sealed space where a large amount of garbage and filth are present.

  In view of the possibility that most negative ions and ozone disappear before reaching the processing target space, the present inventor (1) arranges ozone and negative ions in a sealed space. (2) a more stable composite by reacting negative ions and ozone at an early stage before the negative ions are combined with other components or ozone is decomposed. (3) Immediately after the negative ions and ozone are combined, the processing air is sent to the processing target space after the negative ions and ozone are combined. It may be possible to efficiently deodorize and sterilize by forming a complex that maintains the effect of this, and approaching the odor component, etc., that is positively charged by electrical attraction. One in which the present invention has been completed.

"Device configuration"
The pressurized sterilization / deodorization apparatus according to the best mode includes an airtight chamber (tank) having an air inlet for introducing air from the outside and an air outlet for discharging air to the outside, A single corona discharge type discharge electrode provided, voltage application control means for controlling high voltage to be applied to the needle electrode, and air is sent to the tank via the air introduction port, and the inside of the tank is maintained in a pressurized state. And an air pump and a tubular member connected to the air discharge port. Here, FIG. 1 is a general view showing an example of a pressure sterilization / deodorization apparatus 1 according to the best mode, and FIG. 2 is an internal structure of the pressure sterilization / deodorization apparatus 1 according to the best mode. FIG. Hereinafter, each element will be described in detail with reference to FIGS. 1 and 2.

Storage Case As shown in FIG. 1, the pressurized sterilization / deodorization apparatus 1 according to the best mode has a storage case 10. Here, the storage case 10 is provided with various switches 10a for operating the device 1 and an opening 10b for pulling out a tubular member 15 to be described later from the inside of the device. Here, the size of the storage case 10 varies depending on the application. For example, when the portable case 10 has a portable size that is easy to carry and does not take up space when installed, the volume is 500, for example. ˜5000 cm ³ . The material and shape are not particularly limited, and for example, plastic or aluminum can be used.

Tank As shown in FIG. 2, the tank 11 is composed of an airtight box fixed in the storage case 10 so as not to come into contact with external air. In this best mode, the tank shape is a box shape, but is not limited to this. For example, it may be a cylindrical shape or a semi-cylindrical shape (tunnel shape). Here, the volume of the tank 11, when the housing case 10 is portable size (500~5000cm ^3), 20~200cm ^3, preferably a 50 to 150 cm ^3. In addition, the material of the wall constituting the tank is preferably an insulating material because a high voltage is applied inside, and a corrosive resistant material because corrosive ozone is generated inside. Preferably it is. As such a material, plastic is suitable. In addition, in this best mode, the tank has exemplified the form in which the airtight box with the eight sides integrated is fixed to the bottom surface of the storage case 10, but the present invention is not limited to this. An airtight space (storage case) may be formed by fixing the opening surface downward to the bottom surface of the storage case 10.

  Here, as shown in FIG. 2, the tank 11 discharges air processed by the air introduction port 11 a for introducing pressurized air from the air pump 14 to be described later and the corona discharge type discharge device 12 to the outside. And an air discharge port 11b. A compressed air discharge pipe 14b connected to the air pump 14 is attached to the air introduction port 11a. Here, the compressed air discharge pipe 14b of the air pump 14 is inserted into the air introduction port 11a so that the internal compressed air does not leak to the outside or the external air does not enter the inside through the mounting portion. A sealing process is performed in which a gap between the outer wall of the compressed air discharge pipe 14b and the inner wall of the air inlet port 11a is filled with an adhesive. On the other hand, a tubular member 15 for sending the processing gas to the target space for deodorization and sterilization is attached to the air outlet 11b. Also here, the tubular member 15 is sealed between the air discharge port 11b so that the internal compressed air does not leak to the outside or the external air does not enter the inside through the mounting portion. ing. Further, although not shown, a covered electric wire from the voltage application control means is also introduced into the inside through a hole provided in the tank 11. And the said covered electric wire is connected with the corona discharge system discharge electrode. Here, the above-described sealing process is also applied to the gap between the outer wall of the covered electric wire and the inner wall of the hole.

  Furthermore, in order to ensure stable performance, as shown in FIG. 2, it is preferable that the tank 11 is provided with a pressure regulating valve 11c and a pressurized outlet valve 11d. By adopting such a configuration, a constant high pressure state is always maintained in the tank 11.

Corona Discharge Electrode As shown in FIG. 2, the corona discharge electrode 12 is installed in a tank 11 that is a sealed space. Here, the corona discharge electrode 12 according to the best mode is composed of an electrode having a pair of a needle electrode 12a and a cylindrical electrode 12b. In FIG. 2, four pairs of electrodes are arranged in the tank 11. And both electrodes are connected to the voltage application control means 13 mentioned later through a covered electric wire, and a high voltage is applied to the needle electrode 12a side. When corona discharge is used in this way, negative ions can be generated in the air, and ozone can be further generated by adjusting the voltage. Although there are many combinations of corona discharge type electrodes as discharge electrodes and induction electrodes, the combination of a needle electrode and a cylindrical electrode is outstanding as the performance of the processing gas discharged under pressure.

Voltage Application Control Means As shown in FIG. 2, the voltage application control means 13 can be the one used in the negative ion generator, for example, a circuit called Cockcroft-Walton circuit as shown in FIG. Generates a pulsed high-voltage DC voltage. In particular, when a positive voltage is applied to the needle electrode (periodic voltage of 0, a positive voltage is applied), the generated process gas shows high performance (for example, peak voltage 12 kV, 3.1 kHz). . Here, adjustment of the generation amount of negative ions and ozone is performed by adjusting the magnitude of the voltage (the generation amount of both increases as the voltage increases) and the distance between the needle electrode and the cylindrical electrode, as is well known. Etc. are possible.

Air Pump As shown in FIG. 2, the air pump 14 is not particularly limited as long as pressurized air can be fed into the tank 11. For example, an electromagnetic air pump, a rotary air air pump, a diaphragm vibration air A pump can be mentioned, A commercially available water pump for air tanks and a compressor can be used. Here, the discharge pressure of the air pump is suitably a ^{0.05kg / cm 2 ~7kg / cm 2} , it is more preferably from 0.10~0.20kg / cm ^2. As shown in FIG. 2, the air pump 14 includes an intake port 14 a for taking in air from the outside and a compressed air discharge pipe 14 b for sending air into the tank 11.

Tubular member As shown in FIGS. 1 and 2, the tubular member 15 is connected to the air discharge port 11 b of the tank 11, and is drawn to the outside through the opening 10 b of the storage case 10. Here, the tubular member 15 is comprised from a hose or a pipe. Here, the material of the tubular member 15 is selected according to the use, but since ozone has an oxidative corrosion action, a metallic member that is easily corroded is not suitable. -It is suitable for resin. Specifically, for example, assuming an application to be inserted into a trash can or a waste container, it is preferable to select a flexible material such as a silicon hose or a resin hose, and an application to fix to a container or a refrigerator. When it is assumed, it is preferable to select a high-strength material such as a resin pipe. Here, the diameter and length of the tubular member 15 are preferably 2 to 10 mm (more preferably 3 to 6 mm) and 0.2 to 5 m (more preferably 0.5 to 2.5 m), respectively. In the best mode, the number of tubular members is one. However, the present invention is not limited to this, and a plurality of tubular members may be provided or one may be branched into a plurality.

  Here, in particular, when it is assumed to be used in a place where flammable gas such as methane can be generated, such as being inserted into a trash can or a waste container, flammable gas such as methane enters the tank 11 through the tubular member 15 There is a risk of fire from sparks. Therefore, as shown in FIG. 2, it is preferable to provide the tubular member 15 with a backflow prevention valve 15a. Furthermore, when using it for a fish and fish breeding aquarium, it becomes possible to prevent the reverse flow of water by providing this backflow prevention valve 15a.

  Although not shown in FIG. 2, a corona discharge type discharge electrode may be further provided in the storage case 10 outside the tank 11. In this case, the voltage application control means 12 described above applies a high voltage not only to the corona discharge type electrode 12 in the tank 11 but also to the corona discharge type discharge electrode outside the tank 11. As a result, negative ions and ozone are also generated in the storage case 10 (outside the tank 11). Then, the generated negative ions and ozone are configured to be released to the external space by a discharge port and a fan (not shown) provided in the storage case 10. With this configuration, deodorization and sterilization can be performed at the same time in the space where the storage case 10 is arranged, as well as the processing target space such as a trash can.

<< Application (Usage) >>
The pressure-type sterilization / deodorization apparatus according to the best mode can be applied to various spaces in which generation of odors and bacteria is a problem. For example, highly airtight boxes, such as trash containers such as garbage and diapers, toilets and toilet tanks, highly airtight containers with refrigeration and refrigeration equipment, vehicles with refrigeration and refrigeration equipment, refrigerators, air conditioning indoors and in vehicles A tubular member is inserted directly into a space such as a device. Thus, as a result of the direct introduction of air containing ions and ozone into a highly airtight space, it is freed from the foul odors that rebound when the airtight space is opened. In addition, unlike drugs that decrease in amount over time, active ingredients (air containing ions and ozone) continue to be introduced as long as they continue to operate, regardless of the amount of off-flavor components generated or their duration. It is possible to maintain the deodorizing and sterilizing effect stably. In addition, as a result of introducing an active ingredient (air containing ions and ozone) into the target space through the tubular member, the device main body that may be ignited by using electricity is removed from the target space where there is no risk of ignition. It is also possible to arrange them. Furthermore, as a result of introducing the pressurized air into the target space, it is possible to sterilize and deodorize every corner even in an airtight box containing a lot of dust and the like. In particular, there are more odorous components and bacteria in areas that cannot be reached without pressurized air. In view of this point, it is particularly advantageous to use a configuration in which pressurized air is sent.

  Furthermore, the pressurized sterilization / deodorization apparatus according to the best mode can be used for sterilization / deodorization of seawater and fresh water using an air stone / nano bubble supply source. Thereby, the disinfection and deodorization in a fish breeding aquarium can be performed effectively.
