  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The following embodiment and its modifications include similar components. Therefore, in the following, common reference numerals are given to those similar components, and redundant description is omitted.

  As shown in FIG. 1, the water purification module 1 according to the present embodiment includes a housing 1a. A water purifier 10 capable of removing iron components in the water to be treated such as well water is incorporated in the housing 1a.

  Thus, the apparatus which can perform iron removal can be modularized by incorporating the water purifier 10 in the housing 1a. Therefore, a device capable of removing iron can be installed more easily, and the degree of freedom of installation of a device capable of removing iron can be improved.

  A pipe P0 is connected to the upstream side of the water purifier 10. The pipe P0 is disposed so as to penetrate the side wall of the housing 1a and is exposed to the outside of the housing 1a.

  And the to-be-processed waters, such as well water, can be introduce | transduced in the water purifier 10 by driving the pump 50 installed in the middle or the front-end | tip of piping P0. In addition, it is also possible to incorporate the pump 50 in the water purification module 1.

  On the other hand, a pipe P3 is connected to the downstream side of the water purifier 10. The pipe P3 is also arranged so as to penetrate the side wall of the housing 1a and is exposed to the outside of the housing 1a.

  A faucet 60 is connected to the downstream side of the pipe P3, and the purified water purified by the water purifier 10 passes through the pipe P3 and is discharged from the faucet 60 to the outside. The faucet 60 can also be provided in the housing 1a. That is, the water purification module 1 in which the faucet 60 is installed is also possible.

  The water purifier 10 includes an oxidation unit 20 that is arranged so that tablet-like chlorinated cyanuric acid can come into contact with the water to be treated, a filtration unit 30 that is arranged downstream of the oxidation unit 20, and a downstream side of the filtration unit 30. And an activated carbon unit 40 disposed in the.

  Thus, in this embodiment, the water purifier 10 arrange | positioned in order of the oxidation unit 20, the filtration unit 30, and the activated carbon unit 40 from the upstream is used (refer FIG. 1).

  A pipe P <b> 1 is connected to the downstream side of the oxidation unit 20, and the pipe P <b> 1 is connected to the upstream side of the filtration unit 30. Inside the pipe P1 is a flow path through which primary treated water treated by the oxidation unit 20 flows.

  A pipe P <b> 2 is connected to the downstream side of the filtration unit 30, and the pipe P <b> 2 is connected to the upstream side of the activated carbon unit 40. Inside the pipe P2 is a flow path through which secondary treated water treated by the filtration unit 30 flows.

  The pipe P3 described above is connected to the downstream side of the activated carbon unit 40. Therefore, the inside of the pipe P3 is a flow path through which the tertiary treated water treated by the activated carbon unit 40 flows.

  That is, by using the water purifier 10 of the present embodiment, the water to be treated is treated in stages each time it passes through the oxidation unit 20, the filtration unit 30, and the activated carbon unit 40. And the tertiary treatment water produced | generated by passing the activated carbon unit 40 can be supplied from the tap 60 now as purified water.

  The oxidation unit 20 is designed so that water to be treated comes into contact with chlorinated cyanuric acid solidified in a tablet shape.

By using such an oxidation unit 20, the water to be treated comes into contact with the chlorinated cyanuric acid solidified in a tablet shape, and active chlorine can be released into the water to be treated. Then, ferrous iron dissolved in the water to be treated is oxidized into ferric iron by this active chlorine. Further, ferric iron is converted into an oxidized solid such as ferric hydroxide (Fe (OH ₃ )) by active chlorine. Thus, the oxidation unit 20 enables iron dissolved in the water to be treated to be deposited as ferric hydroxide. Note that the bacteria contained in the water to be treated are also sterilized by active chlorine.

  As chlorinated cyanuric acid, dichloroisocyanuric acid, trichloroisocyanuric acid, or the like can be used.

  Chlorinated isocyanuric acid is a chemically stable solid compound that is easy to handle. When this chlorinated isocyanuric acid is brought into contact with water, the chlorinated isocyanuric acid is hydrolyzed to release active chlorine having a strong oxidizing ability into the water. At this time, since active chlorine released into water from chlorinated isocyanuric acid has excellent stability in water, iron components in water can be oxidized for a longer time.

  Since trichloroisocyanuric acid has a sustained release property than dichloroisocyanuric acid, it can be gradually dissolved over a longer period. Therefore, it is desirable to use trichloroisocyanuric acid from the viewpoint of dissolution rate.

  However, it is not necessary to use only trichloroisocyanuric acid as the chlorinated cyanuric acid. That is, dichloroisocyanuric acid can be used as chlorinated cyanuric acid, or both dichloroisocyanuric acid and trichloroisocyanuric acid can be used. Moreover, it is also possible to use components other than dichloroisocyanuric acid and trichloroisocyanuric acid alone. Furthermore, it is also possible to appropriately select several components from several types of chlorinated cyanuric acids including dichloroisocyanuric acid and trichloroisocyanuric acid and use a tablet in which these components are mixed.

  The tablet-like chlorinated cyanuric acid can be obtained, for example, by using a mold (not shown), filling the mold with powder of the components described above, and pressurizing.

  As such an oxidation unit 20, it is possible to use a chemical | medical agent supply apparatus as shown, for example in FIGS.

  Next, the chemical supply apparatus as the oxidation unit 20 will be described.

  The chemical supply apparatus includes a casing 21 having an inlet 21a through which water to be treated can flow and an outlet 21b through which treated water (primary treated water) can flow out.

  A rotating shaft 22 is provided in the housing portion 21. A medicine holding part 23 is provided in the housing part 21 so as to be able to rotate around the rotation shaft 22.

  The casing portion 21 includes a cylindrical portion 21e provided with an inlet 21a and an outlet 21b at both ends, and a cylindrical portion 21f provided in an arc shape at the center of the cylindrical portion 21e. And the substantially cylindrical space 21c is formed in the center part of the housing | casing part 21, The chemical | medical agent holding | maintenance part 23 is rotatably accommodated in this space 21c.

  The medicine holding part 23 is a substantially cylindrical case, and contains and holds the medicine 24 inside. And at least one part of the chemical | medical agent holding | maintenance part 23 is formed in mesh shape. In the present embodiment, almost the entire surface of the peripheral surface portion 23c and the side surface portion 23d of the medicine holding portion 23 is formed in a mesh shape.

  And the rotating shaft 22 is provided in the center part of the both-sides surface part 23e of the chemical | medical agent holding | maintenance part 23, respectively. The rotating shaft 22 may be provided integrally with the drug holding unit 23 or may be provided separately from the drug holding unit 23.

  Then, the rotation shaft 22 provided in the medicine holding portion 23 is rotatably supported by the bearing 21d provided in the housing portion 21 so that the medicine holding portion 23 can rotate around the rotation shaft 22. It will be provided in the part 21.

  At this time, the chemical | medical agent holding | maintenance part 23 is provided in the housing | casing part 21 so that the lower part can contact the to-be-processed water which flows in from the inflow port 21a. That is, the medicine holding part 23 is arranged in the housing 21 so that the lower part of the medicine holding part 23 is located in the cylindrical part 21e.

  In the present embodiment, the medicine holding part 23 includes a lid part 23a and a medicine containing case 23b, and the medicine 24 can be accommodated in the medicine holding part 23 by removing the lid part 23a. .

  Furthermore, a plurality of partition parts 23e are provided in the medicine storage case 23b, and a plurality of medicine storage parts 23f are defined by the plurality of partition parts 23e. And each medicine container 23f is filled with a tablet-like medicine (chlorinated cyanuric acid hardened in a tablet shape) 24.

  In the present embodiment, the four medicine storage parts 23f are partitioned by the four partition parts 23e, and the four partition parts 23e are also formed in a mesh shape. The number of partition parts 23e is not limited to this. However, when the medicine holding part 23 is rotated once, the partition part 23e flows into the housing part 21 in any state. It is preferably configured to contact water.

  With such a configuration, in the state where the medicine 24 is not accommodated in the medicine holding section 23, the water to be treated that has flowed in from the inflow port 21 a does not receive much resistance due to the medicine holding section 23, and the It can flow downstream. That is, even if the water to be treated is caused to flow into the housing part 21 in a state where the medicine 24 is not stored in the medicine holding part 23, the medicine holding part 23 does not rotate.

  On the other hand, in the state where the medicine 24 is accommodated in the medicine holding part 23, the water to be treated that has flowed from the inflow port 21 a is subjected to resistance by the medicine 24. That is, when the water to be treated is caused to flow into the housing portion 21 while the medicine 24 is accommodated in the medicine holding portion 23, the medicine holding portion 23 is rotated by the water flow. At this time, if the amount of the medicine 24 accommodated in the medicine holding part 23 is reduced, the resistance by the medicine 24 is reduced and the number of rotations of the medicine holding part 23 is reduced.

  Thus, in this embodiment, the chemical | medical agent holding | maintenance part 23 is comprised so that the to-be-processed water which flowed in from the inflow port 21a may rotate around the rotating shaft 22 when the chemical | medical agent 24 contacts. Furthermore, the medicine holding unit 23 is configured such that the number of rotations changes according to the amount of the medicine 24 present. Specifically, since the resistance is large when the amount of the drug 24 is large, the drug holding unit 23 rotates a lot. When the amount of the drug 24 is small, the resistance is decreased and the rotation number of the drug holding unit 23 is decreased. Designed to be. For this reason, when the amount of the medicine 24 decreases, the number of rotations of the medicine holding unit 23 decreases.

  Furthermore, in this embodiment, the rotation detection part 25 which detects whether the chemical | medical agent holding | maintenance part 23 is rotating, and the presentation part 26 which presents the detection result of a rotation detection part are provided.

  In the present embodiment, a pair of electrodes 25 a and 25 b are used as the rotation detection unit 25. Specifically, an electrode 25a is provided on the end face of the rotating shaft 22, and an electrode 25b is provided on the bearing 21d so as to face the electrode 25a. Thus, when the medicine holding part 23 rotates, the electrode 25a and the electrode 25b rotate relatively to generate an induced current.

  Then, the induced current is transmitted as output data to the presentation unit 26 by the wires H connected to the pair of electrodes 25a and 25b, respectively, and the medicine holding unit 23 is rotated by the presentation unit 26. It can be confirmed whether or not.

  In addition, as a method for detecting whether or not the medicine holding unit 23 is rotating, a method of directly incorporating a camera for monitoring an image of the medicine 24, a method of monitoring the remaining amount using light such as an LED, etc. There is no particular problem even if any method is used. However, since the method of providing the electrodes 25a and 25b on the rotating shaft 22 and the bearing 21d is a simple method, it is more preferable to detect by such a method.

  In addition, the presentation unit 26 is a part that receives a signal from the rotation detection unit 25 and notifies the user, and as a presentation method, not only the above method but also a light notification method or a sound notification method may be used. it can.

  It is also possible to form the housing part with a transparent case so that the rotation of the medicine holding part 23 can be detected visually. In this case, the transparent housing unit serves as the rotation detection unit and the presentation unit.

  It is also possible to use a medicine supply device (oxidation unit 20A) as shown in FIG. The configuration illustrated in FIG. 5 is substantially the same as the configuration illustrated in FIG. 2, and is mainly different in that a drug detection unit 27 that detects a drug component is disposed downstream of the drug holding unit 23. It is what. With this configuration, the amount and concentration of the drug component contained in the water that has passed through the drug holding unit 23 can be detected by the drug detection unit 27, and the remaining amount of the drug 24 held in the drug holding unit 23. Can be grasped more reliably. Moreover, since the chemical | medical agent detection part 27 is arrange | positioned without providing a branch part in the flow path of the downstream of the chemical | medical agent holding part 23, it can also suppress that the structure of an apparatus becomes complicated. .

  The filtration unit 30 removes ferric hydroxide from the primary treated water in which iron dissolved in the treated water by the oxidation unit 20 is precipitated as ferric hydroxide.

  As means for filtering, methods such as sand filtration and membrane filtration can be selected as appropriate.

  When filtering by sand filtration, it is preferable to use a filter medium 30a composed of silicon oxide and aluminum oxide. If it carries out like this, it will become possible not only to remove the ferric hydroxide precipitated as a solid, but also to adsorb and remove the iron component that cannot be completely oxidized and is dissolved in the primary treated water. As such a filter medium 30a, 0.35 mm, 0.5 mm, or the like of filter sand manufactured by Tokemi Co., Ltd. can be used.

  Furthermore, if the filtration unit 30 contains 10% or more of the filter medium 30a containing 5% by weight or more of iron, the adsorption filtration ability and the physical filtration ability can be further improved. As such a filter medium 30a, Ferrolite MC2, Ferrolite MC3, Toyolex F2, etc. made by Tochemi Co., Ltd. can be used. In addition, about the magnitude | size of the filter medium 30a, it is suitable to set it as 1 mm or less from a viewpoint of filtration capability.

  Moreover, it is also possible to remove an iron component by membrane filtration, and as such a filtration membrane, a microfilter, an ultrafilter, an RO filter, or the like can be appropriately selected. For example, as a micro filter, U-Tech (registered trademark) MF AM series model A-TWP or model AMSP manufactured by Asahi Kasei Fibers Corporation can be used. Sand filtration and membrane filtration may be used in combination.

  The activated carbon unit 40 performs adsorption filtration so that chlorinated cyanuric acid components such as free chlorine do not flow downstream. This activated carbon is not particularly defined, and white birch (registered trademark) C, granular white birch WH2c manufactured by Nippon Enviro Chemicals Co., Ltd. can be used.

  Note that the activated carbon unit 40 has an adsorption capacity that can adsorb all of the chlorinated cyanuric acid components that are generated when all of the drug 24 stored in the drug holding unit 23 is dissolved as much as possible. It is preferable to configure. By so doing, it is possible to more reliably prevent the chlorinated cyanuric acid component from flowing out downstream.

  Moreover, if the replenishment time of the chemical | medical agent 24 and the replacement | exchange time of the filtration unit 30 or the activated carbon unit 40 are substantially corresponded, the maintenance management of the water purification module 1 or the water purification apparatus 10 will become easy.

  Next, operations of the water purification module 1 and the water purification apparatus 10 having such a configuration will be described.

  First, by operating the pump 50, well water as water to be treated is introduced into the oxidation unit 20 from the inlet 21a through the pipe P0.

  And the to-be-processed water which flowed in from the inflow port 21a contacts the chemical | medical agent (tablet formed with the chlorinated cyanuric acid component) 24 accommodated in the chemical | medical agent holding | maintenance part 23. FIG.

  Thus, by bringing the chemical 24 into contact with the water to be treated, active chlorine is released into the water to be treated. Then, ferrous iron dissolved in the water to be treated is oxidized into ferric iron by this active chlorine. Furthermore, ferric iron is converted into oxidized solids such as ferric hydroxide by active chlorine.

  At this time, since the resistance of the chemical 24 acts on the water to be treated that has flowed from the inlet 21 a, the chemical holding portion 23 that is rotatably provided in the housing portion 21 rotates around the rotation shaft 22. This rotation can be grasped by the rotation detection unit 25 and the presentation unit 26.

  That is, when the water to be treated flows into the oxidation unit 20 from the inlet 21a, the chemical holding unit 23 rotates around the rotation shaft 22 while the water to be treated is in contact with the chemical. Therefore, the contact opportunity with the to-be-processed water of each tablet accommodated in the chemical | medical agent holding | maintenance part 23 can be made more equal. Accordingly, it is possible to prevent the dissolution of the medicine 24 accommodated in the medicine holding part 23 from being partially biased.

  The water that has passed through the medicine holding part 23 becomes primary treated water containing precipitated ferric hydroxide, and this primary treated water is introduced into the filtration unit 30 through the pipe P1.

  And the ferric hydroxide precipitated when the primary treated water introduced into the filtration unit 30 passes through the filter medium 30a is filtered. As a result, secondary treated water from which many iron components have been removed is generated. At this time, if the filter medium 30 capable of adsorbing and removing the iron component dissolved in the water is used, the iron component dissolved in the primary treated water can also be adsorbed and removed, so that more iron component is removed. The secondary treated water can be generated. In addition, when the primary treated water passes through the filter medium 30a, solid impurities and the like contained in the primary treated water are also removed.

  Then, the secondary treated water is introduced into the activated carbon unit 40 through the pipe P2.

  When the secondary treated water is introduced into the activated carbon unit 40, the chlorinated cyanuric acid component contained in the secondary treated water is adsorbed and filtered by the activated carbon provided in the activated carbon unit 40. Thus, tertiary treated water from which the chlorinated cyanuric acid component has been removed is generated. Note that when the secondary treated water passes through the activated carbon, other components dissolved in the secondary treated water are also adsorbed and filtered by the activated carbon.

  The tertiary treated water generated in this way is discharged from the tap 60 through the pipe P0.

  Thus, by using the water purification module 1 and the water purification apparatus 10, the iron component dissolved in the water to be treated can be removed. Therefore, it becomes possible to make purified water suitable for using treated water such as well water containing a large amount of iron components as domestic water such as drinking water.

  Moreover, in the water purification module 1 and the water purification apparatus 10, it is comprised so that a user can be notified by the rotation detection part 25 and the presentation part 26 whether the chemical | medical agent holding | maintenance part 23 is rotating. Therefore, when it is understood that the number of rotations of the medicine holding unit 23 has decreased, or when it is understood that the medicine holding unit 23 is not rotating, the medicine 24 can be replenished. .

  Next, the modification of a water purifier is demonstrated.

  As the water purifier, a water purifier 10B as shown in FIG. 6 can be used. And the water purification module 1B can be obtained by incorporating such a water purification apparatus 10B in the housing 1a.

  Similarly to the water purification apparatus 10, the water purification apparatus 10B includes an oxidation unit 20, a filtration unit 30, and an activated carbon unit 40 that are arranged so that tablet-like chlorinated cyanuric acid can come into contact with the water to be treated in order from the upstream side. ing. The oxidation unit 20 may be the oxidation unit 20A.

  A sterilization unit 70 is disposed on the downstream side of the activated carbon unit 40. That is, the sterilization unit 70 is arranged in the middle of the pipe P3 connected to the downstream side of the activated carbon unit 40.

  As described above, the oxidation units 20 and 20A also have a sterilization ability to sterilize bacteria in the water, and the oxidation units 20 and 20A also serve as a sterilization unit, but the water purifier 10B is different from that. The sterilization unit 70 is further provided.

  By setting it as this structure, the microbe in water is sterilized more reliably and it comes to be able to obtain the water more suitable for a drink.

  As the sterilization unit 70, one having an ultraviolet sterilization unit 70a can be used. Moreover, it can also have the ozone sterilization part 70b. In addition, it is also possible to set it as the sterilization unit 70 which used both the sterilization by an ultraviolet-ray and the sterilization by ozone. FIG. 6 schematically shows an ultraviolet sterilization unit 70a or an ozone sterilization unit 70b.

  As an ultraviolet source of the sterilization unit 70 having the ultraviolet sterilization unit 70a, a general light source that emits a 254 nm sterilization line can be used.

  Furthermore, it is possible to use a light source that can emit not only a 254 nm germicidal line but also a 185 nm germicidal line. That is, it is also possible to have the ultraviolet sterilization unit 70a that generates light in the deep ultraviolet wavelength region. By so doing, it is possible to generate hydroxy radicals having a higher sterilizing ability, and thus the sterilizing ability of the sterilizing unit 70 can be further enhanced.

  As such a light source, SGL-400T4U (Z) or SGL-1000T12EHZ manufactured by DN Lighting Co., Ltd. can be used.

  Moreover, when what has the ozone sterilization part 70b is used as the sterilization unit 70, the continuous sterilization effect can be anticipated by the residual effect of ozone. As a device for applying such ozone, an ozone tube TB120 manufactured by Ozone Associa Co., Ltd. can be used. For example, ozone can be imparted to the treated water flowing downstream of the activated carbon unit 40 by inserting this device in the middle of the pipe P3.

  As described above, the water purifier 10 according to the present embodiment is an apparatus capable of removing iron components dissolved in the water to be treated. And this water purifier 10 has the oxidation unit 20 arrange | positioned so that tablet-like chlorinated cyanuric acid can contact with to-be-processed water, the filtration unit 30 arrange | positioned in the downstream of the oxidation unit 20, and the filtration unit 30. Activated carbon unit 40 disposed on the downstream side.

  As described above, by arranging the oxidation unit 20, the filtration unit 30, and the activated carbon unit 40 in this order from the upstream side, first, the iron component dissolved in the water to be treated in the oxidation unit 20 is oxidized and solidified. It can be deposited as a product. Next, the oxidized solid deposited by the filtration unit 30 can be removed. The chlorinated cyanuric acid component can be removed by the activated carbon unit 40.

  That is, by using the water purifier 10 according to the present embodiment, not only the iron component dissolved in the water to be treated is removed, but also a chlorinated cyanuric acid component that is not suitable for use as drinking water is removed. Will be able to. Therefore, the water to be treated in which the iron component is dissolved can be treated to obtain purified water suitable for use as drinking water or domestic water.

  Moreover, simplification and size reduction of the structure of the water purifier 10 can be achieved by setting it as the structure arrange | positioned in order of the oxidation unit 20, the filtration unit 30, and the activated carbon unit 40 from the upstream.

  Further, in the present embodiment, a chlorinated cyanuric acid that is easy to handle is solidified in a tablet shape as the medicine 24, and the iron component is oxidized by bringing the treatment water into contact with the medicine 24. That is, the iron component dissolved in the water to be treated can be deposited as an oxidized solid without injecting a chemical solution. Therefore, it becomes unnecessary to precisely control the injection amount of the chemical solution, and the water purifier 10 can be handled more safely.

  Further, if the filtration unit 30 contains 10% or more of the filter medium 30a containing 5% by weight or more of iron, the adsorption filtration ability and the physical filtration ability can be further improved. Therefore, more iron components dissolved in the water to be treated can be removed, and water more suitable for beverages can be supplied.

  Further, if the sterilization unit 70 is arranged downstream of the activated carbon unit 40 as in the water purifier 10B, since the bacteria in the water are sterilized by the sterilization unit 70, water more suitable for beverages is supplied. Will be able to.

  And if the sterilization unit 70 has the ultraviolet sterilization part 70a which generate | occur | produces the light of a deep ultraviolet wavelength range, since the hydroxyl radical with higher sterilization capability can be generated, the sterilization capability by the sterilization unit 70 is raised further. be able to.

  In addition, if the sterilization unit 70 includes the ozone sterilization unit 70b, sterilization can be continuously performed due to the residual effect of ozone.

  And if the water purification apparatus 10 and the water purification apparatus 10B which were mentioned above are integrated in the housing 1a and modularized, the water purification module 1 and the water purification module 1B which can show the above-mentioned effect can be obtained.

  Thus, by modularizing, it becomes possible to install more easily, and the installation freedom degree of an apparatus can be improved.

  Further, the chemical supply device as the oxidation units 20 and 20A includes a casing 21 having an inlet 21a through which treated water can flow and an outlet 21b through which treated water can flow out.

  The medicine supply device includes a rotation shaft 22 provided in the housing portion 21, a medicine holding portion 23 that is provided so as to be rotatable around the rotation shaft 22 in the housing portion 21, and holds the medicine 24. It has.

  The medicine supply device further includes a rotation detection unit 25 that detects whether or not the medicine holding unit 23 is rotating, and a presentation unit 26 that presents the detection result of the rotation detection unit 25.

  And the chemical | medical agent holding | maintenance part 23 is comprised so that the to-be-processed water which flowed in from the inflow port 21a may contact the chemical | medical agent 24, and it may be rotated around the rotating shaft 22, and it rotates according to the amount of chemical | medical agent 24 existing. The number is configured to change.

  With this configuration, it is possible to supply the medicine 24 and to simplify and downsize the configuration of the medicine supply device that can detect the remaining amount of the medicine 24 to be supplied. .

  Further, at least a part of the medicine holding part 23 is formed in a mesh shape. In this way, in a state where the medicine 24 is not accommodated in the medicine holding section 23, the water to be treated that has flowed in from the inflow port 21 a is placed on the downstream side of the medicine holding section 23 without much resistance from the medicine holding section 23. It will be able to flow. Therefore, when the water to be treated that has flowed in from the inlet 21a comes into contact with the medicine 24, the medicine holding section 23 that rotates around the rotation shaft 22 and changes in the number of rotations according to the amount of the medicine 24 can be obtained more easily. Can do.

  Furthermore, a drug detection unit 27 that detects a drug component may be arranged on the downstream side of the drug holding unit 23. In this way, the amount and concentration of the drug component contained in the water that has passed through the drug holding unit 23 can be detected by the drug detection unit 27, and the remaining amount of the drug 24 held in the drug holding unit 23 can be more reliably determined. To be able to grasp.

  At this time, it is preferable to arrange the medicine detection unit 27 without providing a branch part in the flow path on the downstream side of the medicine holding unit 23. In this way, it is possible to prevent the device configuration from becoming complicated.
