Description

The present invention relates to an ion transport device for transporting generated ions.

In recent years, air purifiers that use ions to remove mold and viruses in the air are becoming widespread.

However, since the air purifier is used indoors, in the case of a building having a plurality of rooms, it is necessary to install an air purifier in each room.

Therefore, Patent Document 1 discloses an air supply port structure that purifies the air in each room by using a central ventilation unit that ventilates the entire building.

In general, in the central ventilation unit, the length of the duct is inevitably long in order to ventilate the entire building. Therefore, when ions are generated near the inlet of the duct, ions of sufficient concentration cannot be blown out into the room from the outlet of the duct. Therefore, in the air supply port structure disclosed in Patent Document 1, an ion generator is provided on the outlet side of the duct of the central ventilation unit, that is, near the air supply port in the room, so that ions having a sufficient concentration are blown into the room. ing.

However, although the above-mentioned conventional techniques are effective for structures of a relatively large scale such as buildings, they are not effective for structures such as automobiles that are much smaller than buildings. For example, in order to blow out ions having a sufficient concentration into the space, there arises a problem that it is difficult to secure a space for arranging the ion generator in the vicinity of the discharge port in a small structure such as an automobile. In particular, when ions are blown out from a plurality of discharge ports in the same space, it is necessary to arrange an ion generator in the vicinity of each discharge port, so that it becomes more difficult to secure a space for arranging the ion generator.

The purpose is to provide an unnecessary ion transfer device.

In order to solve the above problems, the ion transport device according to one aspect of the present invention includes a blower, an ion generator, and an air inlet that introduces ions generated in the ion generator together with air blown from the blower. And a plurality of ducts having an air discharge port for discharging the air introduced from the air introduction port, and the sum of the opening areas of the air discharge ports of the plurality of ducts combined is the air of the plurality of ducts. rather smaller than the sum of the opening areas of the combined inlet, among the plurality of ducts, the two ducts are arranged close to the air inlet side of each duct, the ion generating device is installed The ion generator installed on the air inlet side of one of the above two ducts generates positive and negative ions in the duct and is installed on the air inlet side of the other duct. The ion generator is characterized in that negative ions or positive ions are generated in the duct. Further, the ion transport device according to another aspect of the present invention includes a blower, an ion generator, an air introduction port for introducing ions generated in the ion generator together with air blown from the blower, and the air introduction port. The sum of the opening areas of the plurality of ducts including the air outlets for discharging the air introduced from the above and the air outlets of the plurality of ducts is the opening of the air inlets of the plurality of ducts. The ion generator is smaller than the sum of the areas, and is characterized in that positive ions and negative ions are generated, the generated ions of one polarity are conveyed by the duct, and the ions of the other polarity are applied to the duct.

[Embodiment 1]
Hereinafter, embodiments of the present invention will be described in detail.

(Ion transfer device)
FIG. 1 shows a schematic configuration of the ion transfer device 101 according to the present embodiment. As shown in FIG. 1, the ion transfer device 101 includes an ion generation unit 1 and a duct 2.

The ion generation unit 1 includes a blower 3 made of a sirocco fan or the like, and an ion generator 4 arranged adjacent to the blower 3 on the downstream side of the wind flow (hereinafter referred to as the leeward side). Therefore, the ion generation unit 1 is driven by the blower 3 to generate wind, and discharges air containing ions (hereinafter, referred to as air ions) generated by the ion generator 4 arranged on the leeward side.

The duct 2 is made of a resin such as polycarbonate, has one air introduction port 2a and two air discharge ports 2b, and is arranged so that the air introduction port 2a abuts on the leeward side of the ion generation unit 1. As a result, the duct 2 conveys the ions generated in the ion generator 4 of the ion generation unit 1 by the air blown out from the blower 3, and discharges air ions from the two air discharge ports 2b. The number of air introduction ports 2a and air discharge ports 2b in the duct 2 is not limited to this.

The air outlet 2b is formed so as to be smaller than the air inlet 2a. As a result, the transport speed of air ions in the duct 2 can be increased as compared with the case where the air discharge port 2b and the air introduction port 2a are the same or the air discharge port 2b is larger than the air introduction port 2a. In general, the faster the air ion transport speed in the duct 2, the smaller the decrease in the ion concentration of the air ion discharged from the air discharge port 2b of the duct. Therefore, by making the air discharge port 2b of the duct 2 smaller than the air introduction port 2a of the duct 2 as in the above configuration, the air ion transport speed in the duct 2 can be increased. This makes it possible to secure the ion concentration of the air ions blown out from the air discharge port 2b of the duct 2. Here, ion concentration is the number of ions per 1 cm ^3.

The duct 2 exerts the above effect if the air outlet 2b is smaller than the air inlet 2a, but preferably, the size of the air inlet 2a is the maximum, and the duct 2 gradually opens toward the air outlet 2b. It is preferable that the size of the air outlet 2b is reduced to the minimum size. Since the transport speed of air ions in the duct 2 thus formed can be reliably increased, it is possible to sufficiently secure the ion concentration of air ions blown out from the air discharge port 2b of the duct 2.

As described above, if the decrease in the ion concentration of air ions in the duct 2 is small, the ion generation unit 1 (or the ion generation device 4) can be arranged on the air introduction port 2a side of the duct 2. As a result, the ion generator 4 may be arranged at one location on the air introduction port 2a side of the duct 2, so that each exhaust can be performed as in the case where the duct 2 has a plurality of air exhaust ports 2b as in the conventional case. It is not necessary to arrange the ion generators 4 as many as the number of outlets, and the shape of the duct 2 and the degree of freedom in installing the air discharge port 2b can be increased. Therefore, in a limited space, the duct 2 can be freely crawled and the air outlet 2b can be freely arranged.

Therefore, although the size of the duct 2 on the air introduction port 2a side depends on the size on the ion generation unit 1 side, the shape and length of the duct 2 and the size of the air discharge port 2b can be freely set. That is, if the air outlet 2b is smaller than the air inlet 2a, the shape and length of the duct 2 and the size of the air outlet 2b can be freely set, so that the duct 2 can be crawled in a narrow space or complicated. It is possible to crawl between various structures. For example, the duct 2 can take various shapes in addition to a circle, an ellipse, a rectangle, a square, and the like within a range in which the internal shape (opening) is 50 mm or less in diameter. Therefore, it is possible to crawl the duct 2 in various places. An example in which the ion transfer device 101 is applied will be described below.

(Application example of ion transfer device 1: Automobile seat)
(A) and (b) of FIG. 2 show an example in which the ion transfer device 101 having the above configuration is applied to the seats 10 and 20 of an automobile.

In the seat 10 shown in FIG. 2A, the ion generation unit 1 is arranged on the back side of the seat surface, and the duct 2 having the three air discharge ports 2b crawls from the back side of the seat surface to the back side of the seat back. It has a structure. Of the three air outlets 2b, one is arranged so as to exhaust air ions from the side of the seat seat surface, and the other two are arranged so as to exhaust air ions from both side surfaces of the back surface of the seat. ing. Each of the three air discharge ports 2b is formed to be smaller than the air introduction port 2a connected to the ion generation unit 1. Here, the inner diameter of the air discharge port 2b is 9 mm. By setting the inner diameter to 9 mm, the effect of making the air discharge port 2b inconspicuous is obtained. However, the inner diameter of the air discharge port 2b is not limited to this.

In the seat 20 shown in FIG. 2B, as in FIG. 2A, the ion generation unit 1 is arranged on the back side of the seat seat surface, and the duct 2 having four air discharge ports 2b is provided in the seat seat. It has a structure that crawls from the back side of the surface to the back side of the back of the seat. Of the four air outlets 2b, two are arranged so as to exhaust air ions from both sides of the seat surface, and the other two are arranged so as to exhaust air ions from both sides of the back surface of the seat. Has been done. Of the two air outlets 2b arranged on both sides of the back surface of the seat, one discharges air ions toward a person sitting on the seat 20, and one is a seat on the back side of the seat 20 (not shown). ), Air ions are discharged. All of the four air discharge ports 2b are formed smaller than the air introduction ports 2a connected to the ion generation unit 1. Further, the total size (sum of opening areas) of the four air outlets 2b is preferably smaller than that of the air inlet 2a.

FIG. 3 shows an example of a duct 2 having a more complicated shape than the duct 2 shown in FIG. Also in this case, since the air discharge port 2b of the duct 2 is formed smaller than the air introduction port 2a, the decrease in the ion concentration of the air ions discharged from the air discharge port 2b is small. As described above, even if the duct 2 has a complicated shape, if the air discharge port 2b is formed smaller than the air introduction port 2a, the decrease in the ion concentration of the air ions discharged from the air discharge port 2b is small. It is possible to secure a sufficient ion concentration. Therefore, if the air outlet 2b is formed smaller than the air inlet 2a, the duct 2 can be crawled to various places.

(Application example of ion transfer device 2: Dashboard of automobile)
For example, as shown in FIG. 4, it is possible to crawl the duct 2 around the dashboard of the automobile 30. In this case, three air discharge ports 2b of the duct 2 are formed, and each of them is arranged so as to discharge air ions toward the inside of the vehicle. Even in this case, each air discharge port 2b is formed to be smaller than the air introduction port 2a of the duct 2 into which the air ions from the ion generation unit 1 are introduced, so that the air is discharged from the air discharge port 2b. It is possible to reduce the decrease in the ion concentration of air ions and discharge the air ions having a sufficient ion concentration into the interior of the automobile 30.

Therefore, by using the ion transport device of the present embodiment, it is possible to freely crawl the duct 2 in the dashboard of the automobile 30 and install the air discharge port 2b at a desired position.

(Application Example 3: Transfer Roller of Copier)
Further, as shown in FIG. 5A, an ion transfer device may be used to remove static electricity from the surface of the transfer roller 41 by blowing air ions onto the transfer roller 41 of the copying machine 40. For example, as shown in FIG. 5B, three ducts 2 may be used to blow air ions onto the surface of the transfer roller 41. Each duct 2 introduces air from the blower 3 from each air introduction port 2a, and is conveyed by the introduced wind by the ion generator 4 arranged in the middle, and from each air discharge port 2b. Air containing ions, that is, air ions are crawled inside the copying machine 40 so as to be blown toward the transfer roller 41. Even in this case, since each air discharge port 2b is formed smaller than the air introduction port 2a, the decrease in the ion concentration of the air ions discharged from the air discharge port 2b is reduced, and a sufficient ion concentration is obtained. Can be blown onto the surface of the transfer roller 41.

As described above, the ion transfer device 101 according to the present embodiment is applied to various places, but can be applied to places other than the above-mentioned automobile seats, automobile dashboards, and copiers. For example, the ion transfer device 101 may be applied to a chair in a restaurant to discharge air ions from the seat surface of the chair. In this case, it is possible to remove the charge on clothes such as the skirt of a person sitting on a chair. In addition, the ion transfer device 101 is built in the seat of the vehicle, and the duct 2 is made to crawl on a complicated path so that air ions are discharged toward people in the vehicle with an air volume or less that does not make them feel uncomfortable. You may. Further, the ion transfer device 101 may be installed near the button of the elevator to discharge air ions toward the person who operates the button. In this case, a person can reduce discomfort in winter by being exposed to air ions before operating the button. Further, by installing the ion transfer device 101 in a printing factory or the like, air ions can be discharged into a narrow space, so that the electrification due to each friction between the members in the narrow space can be removed.

In the ion transfer device 101 according to the present embodiment, the air ions to be transferred are described assuming both positive ions and negative ions, but ions of one polarity may be transferred. However, when transporting ions of one polarity, it is easily affected by the charge inside the duct 2, so it is necessary to devise a method to make it less affected by the charge. That is, it is preferable to have a charge removing mechanism for removing the charge of the duct 2. As described above, by providing the charge removing mechanism for removing the charge of the duct 2, air ions can be conveyed in the duct 2 without being affected by the charge. As a result, the amount of air ions discharged from the air discharge port 2b of the duct 2 can be controlled by the amount of air from the blower 3. An example of the charge removing mechanism will be described in the following embodiments 2 and 3.

[Embodiment 2]
Other embodiments of the present invention will be described below. For convenience of explanation, the members having the same functions as the members described in the above-described embodiment are designated by the same reference numerals, and the description thereof will be omitted.

FIG. 6 is a schematic configuration diagram of the ion transfer device 201 according to the present embodiment. In the ion transfer device 201, as shown in FIG. 6A, two ducts 21 and 21 are arranged adjacent to each other, and the first ion generator 22 that generates negative ions in one duct 21 and the other duct 21 are generated. A second ion generator 23 that generates positive ions and negative ions is installed in the duct 21. Although the blower which is one of the components of the ion transfer device 201 is not shown in FIG. 6A, the structure of the blower is the same sirocco fan as the blower 3 of the first embodiment. The blower is not limited to the sirocco fan, and may be another fan. As shown in FIG. 6B, the first ion generator 22 and the second ion generator 23 are provided in the duct 21 so that the discharge electrode 22a and the electrode 23a project into each duct 21. is set up. As a result, the duct 21 in which the first ion generator 22 is installed carries air containing negative ions (hereinafter, simply referred to as negative ions), and the duct 21 in which the second ion generator 23 is installed carries positive ions. And air containing negative ions (hereinafter referred to as air ions) is carried.

According to the ion transfer device 201, of the two adjacent ducts 21, the second ion generator 23 arranged on the air introduction port 21a side of one of the ducts 21 generates positive ions and negative ions. The first ion generator 22 arranged on the air introduction port 21a side of the other duct 21 generates negative ions. As a result, if the duct 21 in which the first ion generator 22 is installed is first positively charged, the static electricity is eliminated by the generated negative ions, but after that, if the negative ions become excessive, the duct 21 is negatively charged and transported. The concentration of negative ions is reduced. However, of the positive and negative ions of the air ions transported to the duct 21 in which the second ion generator 23 is installed, the positive ions eliminate the static electricity in the duct 21 in which the first ion generator 22 is installed. Therefore, the concentration of negative ions transported to the duct 21 in which the first ion generator 22 is installed does not decrease and is discharged.

Here, the fact that the two ducts 21 are close to each other means that the wall of one duct 21 is in contact with the wall of the other duct 21.

In the above example, the first ion generator 22 generates negative ions, but positive ions may be generated. In this case, contrary to the above, the duct 21 in which the first ion generator 22 is installed is positively charged by positive ions, so that among the positive ions and negative ions generated by the second ion generator 23, negative ions are negatively charged. The static electricity will be removed by the ions.

As described above, in the ion transport device 201, of the two ducts 21, the second ion generator 23 arranged on the air introduction port 21a side of one of the ducts 21 generates positive ions and negative ions. The first ion generator 22 arranged on the air introduction port 21a side of the other duct 21 generates negative ions or positive ions.

Further, in each of the two ducts 21, the air discharge port 21b may be formed smaller than the air introduction port 21a. In this case, similarly to the duct 2 of the first embodiment, the transport speed of negative ions and air ions in the duct 21 of the present embodiment can be increased. As a result, it is possible to sufficiently secure the ion concentrations of the negative ions and the air ions blown out from the air discharge port 21b of the duct 21.

As described above, if the decrease in the ion concentration in the duct 21 is small, the first ion generator 22 and the second ion generator 23 can be arranged on the air introduction port 21a side of the duct 21. As a result, the first ion generator 22 and the second ion generator 23 need only be arranged at one location on the air introduction port 21a side of the duct 2, so that the shape of the duct 21 and the degree of freedom in installing the air discharge port 21b are flexible. Can be enhanced. Therefore, in a limited space, the duct 21 can be freely crawled and the air discharge port 21b can be freely arranged.

In the second embodiment, the charge is removed by using the two ducts 21 and 21, but in the third embodiment below, an example of removing the charge by one duct will be described.

[Embodiment 3]
Other embodiments of the present invention will be described below. For convenience of explanation, the members having the same functions as the members described in the above-described embodiment are designated by the same reference numerals, and the description thereof will be omitted.

FIG. 7 is a schematic configuration diagram of the ion transfer device 301 according to the present embodiment. The ion transfer device 301 includes an ion generator 24 installed on the air introduction port 2a side of the duct 2, and further includes a charge amount detection circuit 25 for detecting the charge of the duct 2. Although the blower which is one of the components of the ion transfer device 301 is not shown in FIG. 7, the structure of the blower is the same sirocco fan as the blower 3 of the first embodiment. Further, the blower is not limited to the sirocco fan, and may be another fan.

The ion generator 24 includes two electrodes 24a and 24b. The electrode 24a is arranged so as to project into the duct 2 to generate negative ions in the duct 2, and the electrode 24b is arranged so as to be close to the surface of the duct 2 and has positive ions on the surface of the duct 2. Occurs. As a result, even if the inside of the duct 2 is negatively charged, positive ions are generated on the surface of the duct 2, so that the positive ions can remove the charge. Therefore, negative ions are excessively generated in the duct 2, and even if negatively charged, the positive ions generated on the surface of the duct 2 remove the charge. Therefore, the ion concentration of the negative ions transported to the duct 2 Does not decrease and is discharged. The electrode 24b may be provided not only close to the surface of the duct 2 but also to face the outer surface.

Here, in the initial stage of transporting negative ions in the duct 2, if the inside of the duct 2 is positively charged, if positive ions are generated from the electrode 24b of the ion generator 24, the charge is removed by the negative ions. The effect of is diminished. Therefore, in the present embodiment, the above-mentioned charge amount detection circuit 25 is provided, and positive ions are generated from the electrode 24b of the ion generator 24 when necessary.

The charge amount detection circuit 25 is a circuit that detects the charge amount of the duct 2, and the detection result is sent to the ion generator 24. The ion generator 24 adjusts the amount of positive ions generated according to the detection result (charge amount of the duct 2) from the charge amount detection circuit 25. That is, the ion generator 24 generates an amount of positive ions that can remove the charge (negative charge) of the duct 2 according to the charge amount of the duct 2. As a result, it is possible to discharge air having a concentration of negative ions equal to or higher than a desired concentration from the air discharge port 2b of the duct 2.

As described above, when the ion transport device 301 having the above configuration generates negative ions and transports them through the duct 2 (resin), the duct is negatively charged, but the positive ions are directly applied to the duct 2 (resin). Removes the charge. As a result, the charging of the duct 2 is eliminated, and negative ions can be discharged from the outlet.

In addition, although FIG. 7 shows an example of transporting negative ions in duct 2, when positive ions are transported in duct 2, positive ions are generated in the duct 2 and negative ions are generated on the surface of the duct 2. It may be generated. In this case as well, the same effect as in the case of transporting negative ions can be obtained.

In the second and third embodiments, an example in which the charge of the duct 2 (duct 21) is removed by ions of opposite polarity to convey the ions of the desired polarity has been described, but the material of the duct is the same as the desired ions. By using a material that is not easily charged with polarity, ions of a desired polarity may be conveyed.

The relationship between the duct material and the ion concentration will be described below with reference to FIGS. 8 and 9.

FIG. 8 shows a measurement system for measuring the ion concentration in the ion transfer device. FIG. 9 shows measurement results obtained by using the measurement system shown in FIG. 8 and materials for explaining the results.

The ion transfer device 401 used in the measurement system includes a blower 31, a duct 32, and an ion generator 33, as in the first embodiment.

The blower 31 is made of a white fan or the like, and is installed at a position where air is blown into the air introduction port 32a of the duct 32.

The duct 32 has an air introduction port 32a and an air discharge port 32b. Here, the duct 32 has a substantially square shape with a side of 30 mm and a length hb of 250 mm in a cross section in the lateral direction orthogonal to the longitudinal direction.

The ion generator 33 is installed on the air introduction port 32a side of the duct 32 so as to generate negative ions in the duct 32. As a result, the ions generated in the duct 32 by the ion generator 33 are conveyed toward the air discharge port 32b of the duct 32 by the wind from the blower 31.

At a position facing the air discharge port 32b of the duct 32, an ion concentration measuring machine 34 for measuring the concentration of ions discharged from the air discharge port 32b is installed.

The ion concentration measuring machine 34 is installed so that the measuring surface is located at a position 100 mm from the air discharge port 32b of the duct 32. The number of ions per cm ³ is measured by the ion concentration measuring machine 34.

The results of measuring the ion concentration for each duct material using the measurement system shown in FIG. 8 are shown in FIG. 9A. Here, the model A and the model B are transport devices provided with ion generators having different amounts of spatial ions, that is, different negative ion generation performances. Here, as shown in FIG. 9B, the amount of spatial ions in model A is larger than the amount of spatial ions in model B. That is, the model A has a higher ability to generate negative ions than the model B.

In model A, when the material of the duct 32 is nylon resin or polyca (PC), the ion concentration is higher than that of model B, and when the material of the duct 32 is polystyrene (PS) or vinyl chloride (PVC), the ion concentration is higher than that of model B. It turns out to be low. Here, the ion concentration is a negative ion concentration.

Therefore, as shown in FIG. 9C, it can be seen that nylon resin and polycarbonate are easily positively charged, and polystyrene and vinyl chloride are easily negatively charged.

From this, it can be seen that there is an optimum combination of duct material selection and ion generation amount selection, and it is necessary to confirm with the material to be implemented. That is, various materials can be considered as the material of the duct, but in consideration of the amount of ions generated, as shown in FIG. 9D, it is difficult to be charged, it is easily charged positively, or it is charged negatively. It is preferable to select the material of the duct depending on whether it is easy to use.

In this way, since the duct is made of a material that is charged to the polarity opposite to the polarity of the ions transported to the duct, the ions are transported by the duct without causing a decrease in the amount of ions due to charging. Can be done. That is, ions of one polarity can be conveyed and discharged with almost no decrease in the amount of ions generated by the ion generator.

[Embodiment 4]
Other embodiments of the present invention will be described below.

FIG. 10 is a schematic configuration diagram of the ion transfer device 501 according to the present embodiment. As shown in FIG. 10A, the ion transfer device 501 is provided with two ion generators (first ion generator 52 and second ion generator 53) in one duct 51. As shown in FIG. 10B, the first ion generator 52 and the second ion generator 53 are arranged at positions facing each other via the duct 51, and are used for discharging in the duct 51. The electrodes 52a and 53a are designed to protrude. Although the blower which is one of the components of the ion transfer device 501 is not shown in FIG. 10A, the structure of the blower is the same sirocco fan as the blower 3 of the first embodiment. The blower is not limited to the sirocco fan, and may be another fan.

In the present embodiment, the first ion generator 52 will be described as an ion generator that generates negative ions, and the second ion generator 53 will be described as an ion generator that generates positive ions and negative ions. The first ion generator 52 may be an ion generator that generates positive ions. Further, the second ion generator 53 may be an ion generator that generates negative ions or positive ions, and the first ion generator 52 may be an ion generator that generates positive ions and negative ions. That is, of the above two ion generators (first ion generator 52, second ion generator 53), one (first ion generator 52) generates positive ions or negative ions, and the remaining one. The platform (second ion generator 53) may generate positive ions and negative ions.

As a result, negative ions generated by the first ion generator 52 are introduced into the duct 51, and the duct 51 carries air containing negative ions (hereinafter, simply referred to as negative ions). On the other hand, positive ions and negative ions generated by the second ion generator 53 are introduced into the duct 51, and air containing positive ions and negative ions (hereinafter referred to as air ions) is conveyed by the duct 51.

The ion transfer device 501 first conveys the negative ions generated by the first ion generator 52 together with the air introduced from the air introduction port 51a of the duct 51, and discharges the negative ions to the outside from the air discharge port 51b of the duct 51. Will be done. As a result, the inside of the duct 51 is negatively charged. If the duct 51 is positively charged in the initial stage, the static electricity is eliminated by the negative ions conveyed to the duct 51. Then, when negative ions become excessive in the duct 51, they are negatively charged. Although air passes through the negatively charged duct 51, the movement of positively and negatively charged particles (dust and dust) is restricted. This is because when the inside of the duct 51 is charged, the repulsive force acts on the particles charged with the same polarity as the inside of the duct 51, and the adsorption force acts on the particles charged with a polarity different from the inside of the duct 51. This is because it becomes difficult for the duct 51 to pass through or enter the duct 51.

After that, the generation of negative ions by the first ion generator 52 is stopped, and the positive ions and negative ions generated by the second ion generator 53 are conveyed together with the air introduced from the air introduction port 51a of the duct 51. It is discharged to the outside from the air discharge port 51b of the duct 51. As a result, static electricity is removed from the negatively charged duct 51 by the positive ions. Then, when the static elimination in the duct 51 is completed, air ions containing positive ions and negative ions are discharged from the air discharge port 51b of the duct 51. At this time, since the duct 51 is statically eliminated, ions can be appropriately conveyed by the duct 51 without causing a decrease in the amount of ions due to charging in the duct 51.

Further, in the duct 51, the air discharge port 51b is formed smaller than the air introduction port 51a as in the duct 21 of the second embodiment. In this case, similarly to the duct 21 of the second embodiment, the transport speed of negative ions and air ions in the duct 51 of the present embodiment can be increased. As a result, it is possible to sufficiently secure the ion concentrations of the negative ions and the air ions blown out from the air discharge port 51b of the duct 51.

As described above, if the decrease in the ion concentration in the duct 51 is small, the first ion generator 52 and the second ion generator 53 can be arranged on the air introduction port 51a side of the duct 51. As a result, the first ion generator 52 and the second ion generator 53 need only be arranged at one location on the air introduction port 51a side of the duct 51, so that the shape of the duct 51 and the degree of freedom in installing the air discharge port 51b are flexible. Can be enhanced. Therefore, in a limited space, the duct 51 can be freely crawled and the air discharge port 51b can be freely arranged. That is, in a limited space (for example, a narrow space), the duct 51 may have various shapes in addition to a circle, an ellipse, a rectangle, a square, etc. within a range of, for example, an internal shape (opening) of 50 mm or less in diameter. Can be taken.

On the other hand, the duct 51 needs to be separable depending on the place where it is installed, the purpose of use, and the like. For example, in the case of a duct for switching air passages in a factory, there is a case of a duct passing between an automobile door and a dashboard.

11A and 11B are diagrams showing a schematic configuration of an ion transfer device 601 provided with a duct that can be separated into two. The ion transfer device 601 basically has the same configuration as the ion transfer device 501 shown in FIG. 10, except that the duct is separably configured.

As shown in FIG. 11A, the ion transfer device 601 has two ion generators (first ion generator 62 and second ion generator 63) installed in the first duct 61. The first ion generator 62 and the second ion generator 63 are arranged at positions facing each other via the duct 61, and are not shown, but are similar to the first ion generator 52 and the second ion generator 53. Each discharge electrode projects into the duct 61. The individual configurations are the same as those of the ion transfer device 501.

The ion transfer device 601 is further provided with a second duct 64 separable on the air discharge port 61b side of the first duct 61. That is, the first duct 61 and the second duct 64 have a separable structure. For example, as shown in FIGS. 12A and 12B, a packing 65 such as urethane foam is provided on the outer peripheral surface of the air discharge port 61b of the first duct 61, and the air introduction port 64a of the second duct 64 is the packing 65. It is conceivable that the second duct 64 is connected to the ion transfer device 601 by partially digging into the air. According to this connection structure, as shown in FIG. 12A, the second duct 64 is placed on the first duct 61 side via the packing 65 from the state where the first duct 61 and the second duct 64 are separated. As shown in FIG. 12 (b), the joint state between the first duct 61 and the second duct 64 can be easily achieved by simply pushing the duct into. Then, the connecting portion between the first duct 61 and the second duct 64 can be sealed by the packing 65. In this way, by adopting the connection structure using the packing 65, the connection / separation between the first duct 61 and the second duct 64 in consideration of the sealing structure of the connection portion is realized by a simple pressing force and pulling force. It becomes possible to do. The connection structure between the first duct 61 and the second duct 64 is merely an example, and is not limited to the above example, and the first duct 61 and the second duct 64 can be connected / separated. It may be a connection structure of.

The air inlet 64a of the second duct 64 is formed to have the same shape and size as the air outlet 61b of the first duct 61, and the air outlet 64b is formed to be smaller than the air inlet 64a. As a result, when the first duct 61 and the second duct 64 are connected, the air discharge port 64b of the ion transport device 601 as a whole is smaller than the air introduction port 61a, so that the first duct 61 and the second duct are smaller. The transport speed of air ions in 64 can be increased.

Generally, in an ion transport device using a separable duct, when the duct is separated, dust or the like invades the duct, and when the duct is reconnected, the dust that has entered the duct is carried by the wind. There is a risk of being discharged from the duct.

In the case of the above-described ion transfer device 601, when the first duct 61 and the second duct 64 are separated, a blower is provided on the first duct 61 side, so that the blower force of the blower is used to inside the first duct 61. Although it is possible to prevent the intrusion of dust and the like, the separated second duct 64 side does not have a function of protecting the intrusion of the dust and the like, so that the dust and the like may invade the inside of the second duct 64.

However, in the ion transfer device 601 having the above configuration, negative ions are released by the first ion generator 62 before the first duct 61 and the second duct 64 are separated. As a result, the inside of the first duct 61 and the second duct 64 is negatively charged. If the first duct 61 and the second duct 64 are resin ducts made of polyethylene or the like that are easily negatively charged, the first duct 61 and the second duct 64 are more likely to be negatively charged. As described above, the negatively charged first duct 61 and the second duct 64 have no problem in transporting air, but polar ions and particles (dust, dust, etc.) are restricted in transport due to charging. .. Therefore, when the first duct 61 and the second duct 64 are separated in this state, as shown in FIG. 11B, the air discharge port 61b of the first duct 61 and the air introduction port 64a of the second duct 64 are separated. Since the air discharge port 64b is formed with a filter (gray portion in the figure) charged by several kilovolts, it is possible to prevent the intrusion of dust and the like.

Generally, in order to prevent the intrusion of dust and the like, it is conceivable to use a filter at the separation part of the duct, but in this case, since the filter cannot pass ions, there arises a problem that the ions cannot be properly conveyed. .. Moreover, if a filter is provided separately, it is inevitable that the cost will increase. On the other hand, as described above, if the filter is charged, it is possible to carry air containing ions without carrying dust and the like, so that it is not necessary to separately provide a filter, and a filter is provided. Compared to the case, it is possible to suppress the increase in cost and reliably transport the ions.

As described above, even if the first duct 61 and the second duct 64 are separated, it is possible to prevent the intrusion of dust and the like. Therefore, it is necessary to separate the first duct 61 and the second duct 64 regularly or as needed. If there is, for example, when switching the air passage of the factory, it is possible to prevent dust or the like from entering the separated duct, so that dust or the like is not discharged from the air passage into the factory. In particular, the ion transfer device 601 of the present embodiment is suitable in a factory that manufactures precision equipment and the like that are easily affected by dust and dirt.

As the first duct 61 and the second duct 64, an example of a resin duct made of polyethylene or the like that is easily negatively charged has been described, but a nylon resin duct that is easily positively charged may be used. When a resin duct that is easily negatively charged is used, the first ion generator 62 preferably generates negative ions, and when a resin duct that is easily positively charged is used, the first ion generator 62 is used. Preferably generates positive ions. That is, the polarity of the ions generated from the first ion generator 62 is preferably the same polarity as the polarity in which the duct is easily charged. In this case, the duct can be easily charged with the same polarity as the polarity of the ions generated by the first ion generator 62.

Further, in the ion transfer device 601, an example in which the duct is separated into two, a first duct 61 and a second duct 64, has been described, but the present invention is not limited to this, and the duct may be separated into three or more.

[Summary]
The ion transport device according to the first aspect of the present invention includes a blower 3, an ion generator 4, an air introduction port 2a that introduces ions generated in the ion generator 4 together with air blown from the blower 3, and the air. A duct 2 having an air discharge port 2b for discharging the air introduced from the introduction port 2a is included, and the air discharge port 2b of the duct 2 is smaller than the air introduction port 2a of the duct 2. ..

In general, the faster the ion transport rate in the duct, the smaller the decrease in the concentration of ions discharged from the duct. Therefore, by making the air discharge port of the duct smaller than the air introduction port of the duct as in the above configuration, the transport speed of air (air ions) containing ions in the duct can be increased. This makes it possible to sufficiently secure the ion concentration of the air ions blown out from the air outlet of the duct.

In this way, even if the ion generator is arranged on the air inlet side of the duct, the decrease in the ion concentration in the duct is small. Therefore, it is necessary to provide the ion generator on the air outlet side of the duct as in the conventional case. Is gone. That is, it is possible to realize an ion transport device that blows out air ions having a sufficient ion concentration from an air discharge port that blows ions into the space and does not require an ion generator to be arranged in the vicinity of the air discharge port.

Therefore, since the ion generator is not provided on the air discharge port side of the duct, the air discharge port can be made smaller, and the duct can be crawled to the target space even in a narrow space or a complicated space. It becomes possible to discharge air ions. That is, the degree of freedom in the shape of the duct and the installation of the air outlet can be increased. For example, even when the air outlets of the ducts are arranged at a plurality of places in the automobile, if the ion transport device having the above configuration is used, the ducts can be freely laid in the automobile to obtain the air outlets. It can be installed in a position.

The ion transport device according to the second aspect of the present invention may include a charge removing mechanism (second ion generator 23, ion generator 24) for removing the charge of the duct 2 in the first aspect.

If the material of the duct is resin, it is easy to be charged (whether it is positively charged or negatively charged depends on the material), so when transporting ions of one polarity, the duct should be charged with the same polarity. For example, the ions cannot be sufficiently transported. That is, air ions having a sufficient ion concentration cannot be obtained on the air outlet side of the duct. Therefore, according to the above configuration, by providing the charge removing mechanism for removing the charge of the duct, air ions can be conveyed in the duct without being affected by the charge. Therefore, the amount of air ions discharged from the air outlet of the duct can be controlled by the amount of air from the blower.

The ion transfer device according to the third aspect of the present invention includes at least two ducts 21 and 21 in the first aspect, and the two ducts 21 and 21 of the ducts 21 and 21 are arranged in close proximity to each other. The ion generators (first ion generator 22 and second ion generator 23) are installed on the air introduction port 21a side of the ducts 21 and 21, and one of the two ducts 21 and 21 is installed. The ion generator (second ion generator 23) installed on the air introduction port 21a side of 21 generates positive ions and negative ions in the duct 21, and is installed on the air introduction port 21a side of the other duct 21. The generated ion generator (first ion generator 22) may generate negative ions or positive ions in the duct 21.

According to the above configuration, of the two adjacent ducts, the ion generator installed on the air inlet side of one duct generates positive ions and negative ions, and the air inlet side of the other duct. By generating negative ions or positive ions, the ion generator installed in the above can remove the charge of the other duct by the positive ions and negative ions conveyed to one duct. For example, if negative ions are transported to the other duct, the duct is negatively charged. Therefore, among the ions transported to one duct close to the other duct, positive ions can be used to remove the charge on the other duct. When positive ions are transported to the other duct, the duct is positively charged, so that the negative ions among the ions transported to the other duct can remove the charge of the other duct.

As a result, ions can be conveyed by the duct without causing a decrease in the amount of ions due to charging.

In the ion transfer device according to the fourth aspect of the present invention, in the above aspect 1, the ion generator 24 generates positive ions and negative ions, and the generated ions of one polarity are conveyed by the duct 2 and the other polarity. Ions may be applied to the duct 2.

According to the above configuration, the ion generator can remove the charge of the duct by transporting the generated ions of one polarity through the duct and applying the ions of the other polarity to the duct. For example, if negative ions are conveyed by the duct, the charge on the duct can be removed by applying positive ions to the duct. Further, if the positive ions are conveyed by the duct, the charge on the duct can be removed by applying the negative ions to the duct.

As a result, ions can be conveyed by the duct without causing a decrease in the amount of ions due to charging.

The ion transport device according to the fifth aspect of the present invention includes the charge amount detection circuit 25 for detecting the charge amount of the duct 2 in the fourth aspect, and the ion generator 24 is detected by the charge amount detection circuit 25. The amount of ions generated on the duct 2 may be set according to the amount of charge.

According to the above configuration, the ion generator sets (adjusts) the amount of ions generated on the duct according to the amount of charge detected by the charge amount detection circuit, so that the ion generator is appropriate according to the amount of charge in the duct. Since a large amount of ions for removing charge can be generated, it is possible to suppress the generation of useless ions (ions not used for removing charge).

In the ion transfer device according to the sixth aspect of the present invention, in any one of the above aspects 1 to 5, the duct (2,21,32) is the ion transferred to the duct (2,21,32). It may be made of a material that is charged to the opposite polarity to the polarity.

According to the above configuration, since the duct is made of a material that is charged to the polarity opposite to the polarity of the ions transported to the duct, the ions are transported by the duct without causing a decrease in the amount of ions due to charging. Can be made to.

In the above aspect 1, the ion transfer device according to the seventh aspect of the present invention includes two of the ion generators, and one of the two ion generators is the first ion that generates positive ions or negative ions. It is preferable that the generator (52,62) and the remaining one are second ion generators (53,63) that generate positive ions and negative ions.

According to the above configuration, the first ion generator transports the generated ions of one polarity to the duct, so that the polarity of the conveyed ions can be charged in the duct. Next, by transporting the positive ions and negative ions generated by the second ion generator to the duct, the charge in the duct can be removed by either the positive ions or the negative ions. For example, if the duct is positively charged, the charge can be removed by negative ions, and if the duct is negatively charged, the charge can be removed by positive ions.

As a result, ions can be appropriately transported by the duct without causing a decrease in the amount of ions due to charging in the duct.

In the ion transfer device according to the eighth aspect of the present invention, in the seventh aspect, the polarity of the ions generated from the first ion generator (52, 62) is determined by the ducts (51, first duct 61, second duct 64). It is preferable that the polarity is the same as the polarity that is easily charged.

According to the above configuration, it is possible to easily charge the duct with the same polarity as the polarity of the ions generated by the first ion generator.

The ion transport device according to the ninth aspect of the present invention preferably has a structure in which the ducts (first duct 61 and second duct 64) can be separated into at least two in the above aspect 8.

According to the above configuration, the duct has a structure that can be separated into at least two, so that the ion transfer device can be applied to various spaces. For example, it is preferable that the duct is separable when the duct is laid between complicated structures.
