Description

  The present invention relates to an air cleaning apparatus that reduces a microorganism such as bacteria in the air that has been distributed by applying a magnetic field to the air that circulates in an air path or suppresses reproduction.

  Conventionally, as this type of air cleaning device, for example, the one described in Patent Document 1 (Japanese Patent Application Laid-Open No. 2001-201169) is known.

As shown in FIG. 15, this conventional air cleaning device Da is constituted by a four-way ceiling-suspended air conditioner. A suction port 1 for sucking indoor air is formed in the center of the bottom surface of the air cleaning device Da. The suction port 1 is provided with a filter 2 made of a magnetic material. Further, the air cleaning device Da is provided with a blower port 3 for blowing the sucked air into the room. The blower opening 3 is provided with a blower flap 4 made of a magnetic material.
Inside the air cleaning device Da, an air passage 5 is formed from the suction port 1 to the blower port 3, and a blower fan 6 and an indoor heat exchange unit 7 are provided in the middle of the air passage 5. The blower fan 6 is made of a magnetic material. A drain pan 8 that receives condensed water generated from the indoor heat exchange unit 7 is provided on the bottom surface of the indoor heat exchange unit 7. The drain pan 8 has a surface made of a magnetic material and an interior made of foamed urethane or the like.

  When the air cleaning device Da is operated, an air flow is formed by the blower fan 6, and indoor air is sucked from the suction port 1 and dust is removed by the filter 2, and then passes through the air passage 5 to exchange indoor heat. It cools by the part 7, and is discharged from the ventilation port 3, the flow direction of air being controlled by the ventilation flap 4. FIG. At this time, a magnetic field from members (filter 2, blower fan 6, surface of drain pan 8 and blow flap 4) formed of a magnetic material is applied to the air sucked into the air cleaning device Da, so that bacteria in the air, etc. The microorganisms are reduced or the propagation is suppressed, and the air is purified.

JP 2001-201169 A

By the way, in such a conventional air purifying device Da, the members (filter 2, blower fan 6, surface of the drain pan 8 and blower flap 4) formed of a magnetic material are dedicated members, so they are already installed. A heat exchange device such as an air conditioner cannot be installed unless the whole or parts are replaced, and there is a problem that the installation cost becomes high. In addition, when the filter is clogged, the filter is replaced. In this case, since the filter is formed of a magnetic material, the manufacturing cost is likely to be higher than that of a filter formed of an existing non-magnetic material. There was a problem.
In addition, since the member formed of a magnetic material has a complicated shape, there is a problem in that it is difficult to increase the strength of the magnetic field and the efficiency of the air cleaning process is deteriorated.

  The present invention has been made in view of the above problems, and can be easily installed in an existing apparatus to reduce the installation cost, simplify the structure, reduce the manufacturing cost, and reduce the magnetic field applied to the air. It is an object of the present invention to provide an air cleaning device capable of increasing the strength and improving the air cleaning efficiency.

  In order to achieve such an object, an air cleaning device of the present invention is provided in an air path surrounded by a cylindrical body through which air flows, and applies a magnetic field to the flowing air. A core composed of a plurality of magnetic bodies provided radially from the center side toward the outer periphery is provided, and the core is formed so as to be fitted to the cylindrical body.

When assembling the core of the air cleaning device, a plurality of magnetic bodies are prepared, for example, the magnetic bodies are directly joined and provided radially.
In this case, since the core has a simple structure in which magnetic bodies are provided in a radial shape, the core can be manufactured more easily than before, the manufacturing cost can be reduced, and the shape of the magnetic body should be simple. Since the number can be easily changed, the strength of the magnetic field formed by the magnetic material can be easily increased.

Moreover, when providing a core in an air path, first, a part of cylindrical bodies, such as a duct, is open | released, and a core is fitted inside a cylindrical body. Then, the opened part of the cylindrical body is returned to the original position.
At this time, since the core only needs to be fitted inside the cylindrical body, it can be easily provided on a cylindrical body such as an existing heat exchanger or a duct of an air conditioning system. Can be made extremely cheap.

  In this state, air is circulated inside the cylindrical body. At this time, the air passing through the core passes between the radially provided magnetic bodies and is exposed to a magnetic field formed by these magnetic bodies. For this reason, microorganisms such as bacteria contained in the air are in a state where a magnetic field is applied, the magnetic field affects the microorganisms, and the microorganisms can be killed to some extent or breeding is suppressed. At this time, if the magnetic field strength of the core is increased, the effect of the magnetic field can be exerted on microorganisms more greatly, the proportion of microorganisms killed can be improved, and the efficiency of air cleaning treatment is improved. Can be made.

Thereafter, the air to which the magnetic field is applied is sent into the room, for example. In the room, the air that has passed through the core and has been cleaned is gradually increasing, and the number of microorganisms in the room air is decreasing. Therefore, the indoor air can be kept clean.
Even if air flows through the cylindrical body, there is a certain amount of space between the magnetic bodies of the core and clogging is difficult, so that there is almost no need for replacement, and maintenance is facilitated.

Further, if necessary, a central member is provided on the core, the magnetic body is constituted by a rectangular plate-shaped permanent magnet having magnetic poles on both sides in the circumferential direction, and each magnetic body is erected outside the central member. is doing.
In this case, since there is a central member, the assembly can be easily performed as compared with the case where the magnetic bodies are directly joined to each other.
In this case, the magnetic body has magnetic poles on both sides in the circumferential direction, so that a magnetic field can be reliably formed in the path through which air passes, and the magnetic field applied to air can be strengthened accordingly.
In this case, since it is a permanent magnet, a magnetic field can be permanently formed, so that maintenance can be facilitated.

Furthermore, if necessary, the magnetic bodies are provided so that the magnetic poles of adjacent magnetic bodies are different from each other.
At this time, since the side surfaces of the adjacent magnetic bodies have different magnetic poles, the direction of the magnetic field between the magnetic bodies is a direction that attracts the magnetic bodies, and the magnetic field is orthogonal to the direction of the air passing between the magnetic bodies. Can be given in the direction of Therefore, since a magnetic field can be efficiently applied to the air, it is possible to easily influence the influence of the magnetic field on microorganisms contained in the air, and the air cleaning treatment efficiency can be improved.

If necessary, the central member is formed of a tubular body, and another magnetic body is disposed in the tubular body.
At this time, if the size of the permanent magnet is increased, the unit price per permanent magnet is significantly increased. However, since the tubular body is provided and the magnetic body is erected outside the permanent magnet, the size of the permanent magnet is increased. In this respect, the size of each permanent magnet can be reduced, and the unit price of the permanent magnet can be reduced accordingly, and the manufacturing cost of the entire air cleaning device can be reduced. .

In this case, since the central member is formed of a tubular body, air can be passed through the tubular body, air flow rate can be ensured, and air can easily pass through, improving the efficiency of air cleaning treatment. Can be made.
In addition, since another magnetic body is provided inside the tube, a magnetic field can be applied to the air passing through the tube.

Next, the core is preliminarily fitted to a connecting cylinder that constitutes the air path and has connecting portions at both ends.
When attaching this air purifying device, for example, the connecting portion of the connecting cylinder can be connected to the duct, and the installation can be facilitated, and the installation cost can be reduced.

The surface magnetic flux density B of the magnetic material is desirably 50 mT (millitesla) ≦ B ≦ 1500 mT (millitesla).
In this case, it becomes easy to affect the microorganisms contained in the air flowing through the cylindrical body, and the microorganisms in the air can be easily reduced.

  According to the air cleaning device of the present invention, the air purification apparatus includes a core composed of a plurality of magnetic bodies provided radially from the center side of the air path toward the outer periphery, and the core is formed so as to be fitted to the cylindrical body. It can be easily provided on an existing cylindrical body, and the installation cost can be reduced. In addition, the core has a simple structure and can increase the magnetic field strength. When the magnetic field strength is increased, the core can be affected more effectively, and the air cleaning efficiency can be improved. Furthermore, since there is a certain amount of space between the magnetic bodies of the core and clogging is difficult, there is almost no need for replacement, and maintenance is facilitated.

  In addition, when the core is provided with a central member, the magnetic body is formed of a rectangular plate-shaped permanent magnet having magnetic poles on both sides in the circumferential direction, and each magnetic body is erected outside the central member, the central member is Therefore, as compared with the case where the magnetic bodies are directly joined together, the assembly can be easily performed. Further, the magnetic body has magnetic poles on both sides in the circumferential direction, so that a magnetic field can be reliably formed in the path through which air passes, and the magnetic field applied to air can be strengthened accordingly. Furthermore, since it is a permanent magnet, a magnetic field can be formed permanently, so that maintenance can be facilitated.

  Hereinafter, based on an accompanying drawing, an air cleaner concerning an embodiment of the invention is explained in detail.

  As shown in FIGS. 1 to 3, the air cleaning device D1 is provided in an air path 41 surrounded by a tubular body 40 through which air flows and applies a magnetic field to the flowing air.

As shown in FIG. 4, the air cleaning device D <b> 1 is attached to an air conditioning system including a heat exchanger 10.
As shown in FIGS. 5 and 6, the heat exchanger 10 includes a rectangular parallelepiped housing 11, a delivery port 12 for sending air into the room, a suction port 13 for taking in outdoor air outside, and a suction for taking in air in the room. The port 14 includes an exhaust port 15 for exhausting the taken-in air to the outside of the room, and a heat exchange unit (not shown) provided inside the housing 11 and capable of heating or cooling the taken-in air.
The delivery port 12, the suction port 13, the suction port 14, and the exhaust port 15 have the same shape, respectively, and a funnel-shaped body portion 16 whose diameter decreases from the housing 11 side toward the distal end side, and a distal end of the body portion 16. And an insertion portion 17 that can be inserted into the duct.
In FIG. 5 and FIG. 6, 10 a is an operation panel for operating the heat exchanger 10.

As shown in FIG. 4, the air conditioning system using the heat exchanger 10, for example, sends air so that air can be sent from a delivery port 12 to a plurality of rooms R (three in the embodiment). An outlet 12 and an air outlet 18 of each room R are connected via a duct 20. In addition, this air conditioning system is configured such that the suction port 14 and the air suction port 19 of each room R are connected by a duct 21 so that air from a plurality of rooms R can be taken from the suction port 14.
In the embodiment, the cylindrical body 40 is configured by the air outlet 12 of the heat exchanger 10.

  As shown in FIGS. 1 to 3, the air purifier D <b> 1 is a core composed of a plurality (ten in the embodiment) of magnetic bodies 30 provided radially from the center side of the air path 41 toward the outer periphery. C is provided, and the core C is configured to be fitted to the cylindrical body 40.

The magnetic body 30 is composed of a rectangular plate-shaped permanent magnet having magnetic poles on both sides in the circumferential direction. Further, as shown in FIG. 2, each magnetic body 30 is erected by being fixed to the outside of the tubular body 35 as a central member with an adhesive so that the magnetic poles of adjacent magnetic bodies 30 are different from each other. Is provided. Furthermore, each magnetic body 30 is provided in an equiangular relationship, and a surface that does not have a magnetic pole is provided on the outer side on one end side of the tubular body 35.
These magnetic bodies 30 use those whose surface magnetic flux density B is 50 mT (millitesla) ≦ B ≦ 1500 mT (millitesla).

The magnetic body 30 according to the embodiment is constituted by, for example, two rectangular plate-shaped permanent magnets 31 formed in a length of 40 mm, a width of 40 mm, and a thickness of 10 mm and bonded to each other with faces having different magnetic poles facing each other. , 40 mm long, 40 mm wide, and 20 mm thick.
As the permanent magnet 31 of the embodiment, for example, a measured magnetic flux density having a surface magnetic flux density of 148.6 mT (millitesla) on the north pole side and 149.6 mT (millitesla) on the south pole side was used. The surface magnetic flux density B of the magnetic body 30 in which the two permanent magnets 31 were joined was 170.0 mT (millitesla) on the N pole side and 170.0 mT (millitesla) on the S station side.

  Moreover, the tubular body 35 as the central member is constituted by a resin pipe formed with a diameter of 60 mm and a thickness of 10 mm, for example. Another magnetic body 30 is disposed in the tubular body 35 as the central member. The other magnetic body 30 is the same as the magnetic body 30 provided radially, and is provided in the pipe body 35 by joining the end surface of the magnetic pole 30 and the inner wall of the pipe body 35 with an adhesive. Yes. The magnetic body 30 disposed in the tubular body 35 is provided for applying a magnetic field to the air passing through the tubular body 35.

When assembling the core C, which is the air cleaning device D1, for example, eleven magnetic bodies 30 formed by joining two permanent magnets 31 are prepared in advance, and 10 of these are bonded to the pipe body 35 with an adhesive. Adhere to the outside in an equiangular relationship. Then, one magnetic body 30 is inserted into the tube body 35 and the magnetic body 30 is bonded to the inner wall of the tube body 35 with an adhesive.
At this time, since the core C has a simpler structure than the conventional one, the manufacturing cost can be reduced, and since the core structure is simple, the magnetic field strength of the core C can be set high.
At this time, if the magnetic body 30 is made of a single permanent magnet, the size of the magnetic body 30 increases and the magnetic body 30 greatly increases. However, since the magnetic body 30 is formed by joining two permanent magnets 31, the magnetic body 30 is magnetic. Compared to the case where the body 30 is formed of a single permanent magnet, the price per one magnetic body 30 can be kept low, and the manufacturing cost of the entire air cleaning device D1 can be reduced.

Further, at this time, the tubular member 35 as the central member is a non-magnetic material and does not form a magnetic field, and therefore does not affect the magnetic member 30 adhered to the tubular member 35. Therefore, the magnetic member 30 can be easily adhered and easily assembled. Can be performed.
Furthermore, at this time, since the tubular body 35 is provided and the magnetic body 30 is erected on the outside thereof, the size of the permanent magnet 31 can be reduced to some extent. Therefore, the unit price of the permanent magnet 31 can be kept low, and the manufacturing cost of the entire air cleaning device D1 can be reduced.

When the core C as the air cleaning device D1 is provided in the air path 41, first, the duct 20 is removed from the insertion portion 17 of the outlet 12 of the heat exchanger 10, as shown in FIG. Next, in the state where the other end portion of the tube body 35 of the core C is gripped and the axis of the tube body 35 is coaxial with the axis of the insertion portion 17 of the delivery port 12 which is the cylindrical body 40. Is inserted into the insertion portion 17, and the core C is fitted into the insertion portion 17. And the duct 20 is fitted in the insertion part 17, and it returns to an original state.
At this time, since the core C can be installed simply by fitting inside the cylindrical body 40, it can be easily provided in the existing heat exchanger 10, and the installation cost is extremely low compared to the conventional case. be able to.

  In this state, the heat exchanger 10 is operated to take in the inside air in the room R from the suction port 14 through the suction port 19 and the duct 21, and the air is heated or cooled inside the heat exchanger 10. Or it is made to send out from the delivery port 12 in the state as it is. In this case, the air passing through the delivery port 12 is divided into the outside of the tube body 35 and the inside of the tube body 35 at the location where the core C is provided, and then merges and passes through the duct 20 to the room R. It will be sent in.

At this time, the air passing outside the tubular body 35 passes between the magnetic bodies 30 provided radially and is exposed to a magnetic field formed by these magnetic bodies 30. On the other hand, the air passing through the inside of the tubular body 35 is exposed to a magnetic field formed by the magnetic body 30 inside the tubular body 35. For this reason, microorganisms such as bacteria contained in the air are in a state where a magnetic field is applied, the magnetic field affects the microorganisms, and the microorganisms can be killed to some extent or breeding is suppressed.
At this time, the core C has a simple structure and can easily increase the magnetic field strength. When the magnetic field strength is increased, the influence of the magnetic field can be exerted on the microorganism more greatly, and the rate of death of the microorganism can be increased. It is possible to improve the efficiency of the air cleaning process.

At this time, since the central member is constituted by the pipe body 35, air can be passed through the pipe body 35, the air flow rate can be secured, and air can easily pass through. Processing efficiency can be improved.
At this time, the magnetic body 30 joins the two permanent magnets 31 to increase the surface magnetic flux density B and forms a stronger magnetic field as compared with the case where the single permanent magnet 31 is used as it is. Therefore, the influence of the magnetic field can be easily exerted on the microorganisms contained in the air, and the air cleaning treatment efficiency can be improved.

  At this time, since the side surfaces of the adjacent magnetic bodies 30 have different magnetic poles on the outside of the tubular body 35, the direction of the magnetic field between the magnetic bodies 30 is the direction in which the magnetic bodies 30 are attracted to each other. The magnetic field can be applied in a direction orthogonal to the direction of the air passing through 30. Therefore, since a magnetic field can be efficiently applied to the air, it is possible to easily influence the influence of the magnetic field on microorganisms contained in the air, and the air cleaning treatment efficiency can be improved.

Next, the air to which this magnetic field is applied is sent into the room. In the room R, the air that has passed through the core C and has been cleaned is gradually increasing, and the number of microorganisms in the room air is decreasing. Therefore, the air in the room R can be kept clean.
Even if the heat exchanger 10 is operated and air flows through the cylindrical body 40, the magnetic bodies 30 of the core C are somewhat wide and hardly clogged. Becomes easier.

FIG. 7 shows an air cleaning device D2 according to another embodiment.
The air cleaning device D2 includes a core C similar to that of the above embodiment. The air cleaning device D2 includes a connection cylinder 37 that forms an air path 41 and has connection portions 38 at both ends. The core C is provided by being fitted in the connection cylinder 37 in advance so that the axis of the tube 35 and the axis of the connection cylinder 37 are coaxial.
The connection cylinder 37 is constituted by a resin pipe having a circular cross section, for example. Moreover, the connection part 38 of the connection cylinder 37 is formed in the diameter smaller than the general part of the connection cylinder 37 so that it can be penetrated in the inside of a cylinder, for example.
For example, as shown in FIG. 4, the air cleaning device D <b> 2 is attached to a duct 20 on the outlet 12 side of the heat exchanger 10.

When attaching the air purifying apparatus D2 of this embodiment, for example, a part of the duct 20 is cut, and the connecting cylinder 37 is connected to this portion.
In this case, since the duct 20 is cut and the connection cylinder 37 is connected to this location, it can be easily attached to an air conditioning system using the existing heat exchanger 10, and the installation cost can be reduced.
When the heat exchanger 10 is operated with the air cleaning device D2 of this embodiment attached, the same actions and effects as in the case of the air cleaning device D1 of the above embodiment are obtained.

The position where the air purifier D2 is attached is provided immediately after the delivery port 12. However, the position is not limited to this, and as shown in FIG. 8, it is provided immediately before the air outlet 18 of each room R. Also good.
In the embodiment, the air cleaning devices D1 and D2 are provided in the delivery port 12 and the duct 20 on the delivery port 12 side. However, the present invention is not limited to this, and the suction port 13, the suction port 14, and the suction port are not limited thereto. It may be provided at any location of the duct 21 connected to the port 13 and the duct 21 connected to the suction port 14 and may be appropriately changed.

[Experimental example]
As an experiment example, when the air purification device D1 is provided at the delivery port 12 of the heat exchanger 10 and when the air purification device D1 is not provided at the delivery port 12 of the heat exchanger 10, the microorganisms can be treated. A comparative experiment was performed.

In this comparative experiment, as shown in FIG. 9, the heat exchanger 10 is installed in a sealed room R (75 m ³ ), and the air in the room R is continuously discharged from the inlet 14 of the heat exchanger 10. The air is sucked out and air is sent out from the delivery port 12. For each elapsed time, the number of general bacteria in the air in the room R (1000 liters) and the number of fungi in the air in the room R (1000 liters) are obtained. Examined.
Further, in this comparative experiment, in order to examine the possibility that general bacteria and fungi were adsorbed to the magnetic body 30 of the air cleaning device D1, the general bacteria per predetermined area (40 cm ² ) attached to the magnetic body 30 were analyzed. The number and the number of fungi per predetermined area (40 cm ² ) attached to the magnetic body 30 of the air cleaning device D1 were also examined.

  The magnetic body 30 of the core C of the air cleaning device D1 used in this comparative experiment is a 1850 gauss A-manufactured permanent magnet made of a combination of two 40 x 40 x 5 mm magnets, with a diameter of Ten sets were fixed radially to a cylindrical body 40 made of polyvinyl chloride of 150 mm, and one set was fixed to a pipe body 35 made of polyvinyl chloride in the center. As a result, the maximum width between the magnets was 1800 gauss.

The microbiological test was performed according to a hygiene test method (for example, described in Japanese Pharmacy Society: Sanitary test method / comment, Kanbara Publishing (2000)).
In addition, the microorganism sample was aspirated using a RCS Plus air sampler manufactured by Biotest, at a point 1.5 m high, 3 m away from the outlet 12 of the heat exchanger 10.
For general bacteria, 200 liters of air was sucked and then agar strip TC (manufactured by Biotest Co., Ltd.) was used to measure the bacteria by culturing at 30 ° C. for 2 days.
The growth of the fungus was measured by culturing at 25 ° C. for 5 days with 1000 liters of suction and using Agar Strip YM (Biotest Co., Ltd.).
In this comparative experiment, a heat exchange / ventilation unit VN-350SS2 manufactured by Toshiba Corporation was used as the heat exchanger 10. The air volume from the outlet 12 of the heat exchanger 10 was set to 350 m ³ / h.

(1) Number of general bacteria in air (1000 liters) in the room R at every elapsed time FIG. 10 shows the results. About general bacteria, in order to match the amount of suction with fungi, it was converted to 1000 liters. When air was flowed without providing the air cleaning device D1, the number of bacteria at the start was 2.5 times or more in 3 hours, then turned to decrease, and after 24 hours, it returned to the same number or more at the start. It was. On the other hand, when the air purifier D1 was provided and air was flowed, the number of bacteria at the start was nearly doubled in 1 hour, which was similar to the absence of a magnetic field, but after 3 hours it decreased significantly. The decrease was maintained even after 24 hours. Thus, when air was flowed, the presence of a magnetic field resulted in a decrease in the number of floating general bacteria.

(2) Number of fungi in air (1000 liters) in room R for each elapsed time FIG. 11 shows the results. As for floating fungi, the initial bacterial count itself was not large, but when air was flowed without providing the air cleaning device D1, it nearly doubled in 3 hours and then decreased slightly, but after 24 hours, More than the number of bacteria at the start. On the other hand, when the air purifier D1 was provided and air was allowed to flow, it was halved after 1 hour, and no fungus was detected after 9 hours. Thus, when air was flowed, the presence of a magnetic field resulted in a decrease in the number of floating fungi.

(3) Number of general bacteria per predetermined area (40 cm ² ) attached to the magnetic body 30 for each elapsed time FIG. 12 shows the results. The number of general bacteria adhering to the magnetic body 30 of the air cleaning device D1 was slightly detected at the third hour, but thereafter began to decrease, and was not detected from the ninth hour.
(4) Number of general bacteria per predetermined area (40 cm ² ) attached to the magnetic body 30 for each elapsed time FIG. 13 shows the results. The number of general bacteria adhering to the magnetic body 30 of the air cleaning device D1 was slightly detected after 1 hour, but thereafter began to decrease and was not detected from the 3rd hour.

  FIG. 14 shows the environmental conditions at the time of measurement in the above experiment. The temperature was about 15 ° C. to 25 ° C., and the humidity was 50 to 60%.

  From the above results, it is understood that when air is allowed to pass through the magnetic field formed by the magnetic body 30 of the air cleaning device D1, the floating general microorganisms are greatly reduced compared to those that do not allow the magnetic field to pass, and are extremely effective. It was. In addition, it was also found that microorganisms floating in the air are affected by a magnetic field and their growth is likely to be suppressed rather than being reduced by adhering to the magnet.
