It is provided with a hypochlorous acid storage unit for storing the supplied hypochlorous acid aqueous solution and a delivery unit for transporting the hypochlorous acid aqueous solution from the hypochlorous acid storage unit to the hypochlorous acid release unit. The hypochlorous acid release part is composed of a hollow body formed of a material that is more compatible with hypochlorous acid than water, and the hypochlorous acid is contained in the hollow body from the hypochlorous acid storage part via a delivery part. When the aqueous solution is supplied, hypochlorous acid is refined in the process of permeation of hypochlorous acid from the inside of the hollow structure of the hollow body to the outside, and the finely divided hypochlorous acid is put into the air in the air air passage. discharge.

Since the hollow body constituting the hypochlorous acid discharging portion of the space purification device according to the present disclosure is formed of a material having a higher compatibility with hypochlorous acid than water, it is outside the hollow structure of the hollow body. Hypochlorous acid is more likely to penetrate than water. That is, hypochlorous acid is preferentially released from the outer surface of the hypochlorous acid release portion (the surface on the air air passage side) to the air air passage. That is, according to the configuration of the space purification device according to the present disclosure, the air sucked from the suction port comes into contact with hypochlorous acid that preferentially permeates the hypochlorous acid discharge portion provided in the air air passage. By doing so, air containing hypochlorous acid is released from the air outlet to the target space through the air air passage. Therefore, the target space is not excessively humidified, and the relative humidity of the target space is not increased. As a result, the space purification device according to the present disclosure can obtain the sterilization and deodorizing effects of hypochlorous acid according to the purpose while maintaining the comfort of the target space. That is, the space purification device according to the present disclosure can contribute to the purification of the target space while suppressing an increase in the amount of humidification.

Further, the space purification device according to the present disclosure further detects and detects the temperature of the temperature control unit for adjusting the temperature of the hypochlorous acid aqueous solution sent from the hypochlorous acid storage unit and the temperature of the air sucked from the suction port.

It includes a control unit that controls the operation of the adjustment unit. Then, the control unit may determine the operation of the temperature control unit based on each signal output from each of the suction temperature detection unit and the outlet temperature detection unit.

For example, the control unit controls the temperature control unit so as to adjust the temperature of the hypochlorous acid aqueous solution so that the temperature detected by the blowout temperature detection unit and the temperature detected by the suction temperature detection unit are equal to each other. As a result, the space purification device according to the present disclosure reduces the temperature of the air containing hypochlorous acid blown out from the outlet (the temperature decrease that occurs when hypochlorous acid is released into the air flowing in the air passage). Can be prevented. That is, since the space purification device according to the present disclosure can prevent the temperature of the target space from being lowered, it is possible to prevent the user from being uncomfortable due to the room temperature decrease.

Further, the space purification device according to the present disclosure further includes an air passage wall of an air air passage at a position facing the delivery portion, and the hypochlorous acid discharge portion has a folded portion at a portion reaching the air passage wall. ing. Then, the folded-back portion is located on the shelf protruding from the air passage wall in the installed state of the space purification device, and on the shelf, the rotating body arranged inside the folded-back portion and the shock absorber arranged outside are formed. Be retained. Further, the rotating body is configured to be eccentric with respect to the rotation axis of the rotating body, and may rotate in the direction of the flow of the hypochlorous acid aqueous solution flowing in the hypochlorous acid discharging portion.

When the hypochlorous acid release part is made of a material that is more compatible with hypochlorous acid than water, such as silicon resin, it is easily deformed by an external force. In such a case, in the space purification device according to the present disclosure, the rotating body rotates in the direction of the flow of the hypochlorous acid aqueous solution flowing in the hypochlorous acid release part and comes into contact with the hypochlorous acid release part. , The hypochlorous acid release part is deformed and the hypochlorous acid aqueous solution in the hypochlorous acid release part is pushed out. As a result, in the space purification device according to the present disclosure, the passing speed of the hypochlorous acid aqueous solution passing through the hypochlorous acid discharging portion becomes high, so that the hypochlorous acid discharging portion is refined and released into the air. The amount of hypochlorous acid increases. Therefore, the space purification device according to the present disclosure can easily improve the sterilization and deodorizing effects of hypochlorous acid without increasing the concentration of hypochlorous acid in the hypochlorous acid storage portion.

Further, the space purification device according to the present disclosure is further provided in the hypochlorous acid storage unit, detects the hydrogen ion concentration index of the hypochlorous acid aqueous solution, and signals the hydrogen ion concentration index of the detected hypochlorous acid aqueous solution. By adding a hydrogen ion concentration index adjuster to the hypochlorous acid aqueous solution, which is provided in the concentration detection unit and the hypochlorous acid storage unit, the hydrogen ion concentration index of the hypochlorous acid aqueous solution can be obtained. It is provided with a concentration adjusting unit for adjusting. Then, the control unit may control the operation of adding the hydrogen ion concentration index adjusting agent to the hypochlorous acid aqueous solution by the concentration adjusting unit based on the signal regarding the hydrogen ion concentration index from the concentration detecting unit.

Thereby, the space purification device according to the present disclosure can change the abundance ratio of free hypochlorous acid in the hypochlorous acid aqueous solution in the hypochlorous acid storage unit. Therefore, the space purification device according to the present disclosure can change the miniaturization rate of hypochlorous acid that permeates the hollow body constituting the hypochlorous acid release part, and hypochlorous acid from the hypochlorous acid release part. It becomes possible to control the amount of chloric acid released. For example, when a hydrogen ion concentration index adjuster is added so as to decrease the hydrogen ion concentration index in the hypochlorous acid aqueous solution, the hypochlorous acid in the hypochlorous acid aqueous solution can be increased. For this reason, the rate of miniaturization of hypochlorous acid that permeates the hollow body increases, so that the space purification device according to the present disclosure can increase the amount of hypochlorous acid released from the hypochlorous acid release portion. it can.

Hereinafter, the space purification device according to the embodiment of the present disclosure will be described with reference to the drawings.

(Embodiment 1)
First, the space purification device 1 according to the first embodiment of the present disclosure will be described with reference to FIGS. 1 and 2. FIG. 1 is a schematic view of the space purification device 1 according to the first embodiment of the present disclosure. FIG. 2 is a schematic view of the hypochlorous acid release unit 6 constituting the space purification device 1.

The space purification device 1 is a device that contains hypochlorous acid in the air 4a taken in from the target space and releases it in order to sterilize and deodorize the target space. In the following, as shown in FIG. 1, the vertical direction in the state where the space purification device 1 is installed (corresponding to the installation state according to the present disclosure) may be described as the vertical direction. Further, as shown in FIG. 1, the upper surface in the state where the space purification device 1 is installed may be described as the top surface, and the lower surface may be described as the bottom surface. The same applies to the space purification device according to the other embodiment.

Specifically, as shown in FIG. 1, the space purification device 1 includes a suction port 2, an air outlet 3, an air air passage 4, a blower unit 5, a hypochlorous acid release unit 6, and a hypochlorous acid. A chloric acid storage unit 7, a delivery unit 8, and a housing 9 are provided.

The space purification device 1 is composed of an outer frame of the device by a housing 9 having a suction port 2 which is an opening for sucking air 4a from the target space and an outlet 3 for blowing out the air 4a sucked from the suction port 2 on the upper surface. Will be done.

Inside the housing 9, there are an air air passage 4 that communicates between the suction port 2 and the air outlet 3, and a blower portion 5 that creates a flow that sends out the air 4a sucked from the suction port 2 from the air outlet 3. A hypochlorous acid release unit 6, a hypochlorous acid storage unit 7, and a delivery unit 8 are provided. That is, the space purification device 1 sends out the air air passage 4 formed between the suction port 2 and the air outlet 3 and the air 4a sucked from the suction port 2 to the air outlet 3 via the air air passage 4. It is provided with a blower unit 5.

The hypochlorous acid release unit 6 releases gaseous hypochlorous acid to the air 4a flowing in the air air passage 4. That is, the space purification device 1 is provided in the air air passage 4, and includes a hypochlorous acid discharge unit 6 that releases hypochlorous acid into the air air passage 4. Details of the hypochlorous acid release unit 6 will be described later.

The hypochlorous acid storage unit 7 is composed of a container having a predetermined capacity, and stores a hypochlorous acid aqueous solution to be supplied to the hypochlorous acid release unit 6. The hypochlorous acid storage unit 7 and the hypochlorous acid release unit 6 are connected by a pipe 10 penetrating the side wall of the hypochlorous acid storage unit 7.

The delivery unit 8 is a pressure pump that applies pressure to the hypochlorous acid release unit 6 to send out the hypochlorous acid aqueous solution stored in the hypochlorous acid storage unit 7. That is, the space purification device 1 includes a delivery unit 8 for transporting an aqueous hypochlorous acid solution from the hypochlorous acid storage unit 7 to the hypochlorous acid release unit 6.

That is, in the space purification device 1, the air 4a in the target space is sucked from the suction port 2 by the operation of the blower unit 5, and the sucked air 4a circulates in the air air passage 4 and becomes the hypochlorous acid release unit 6. After contacting, it is configured to be blown out from the air outlet 3 into the target space.

Next, the hypochlorous acid release unit 6 will be described in detail.

The hypochlorous acid release unit 6 is composed of a hollow body, and when an aqueous hypochlorous acid solution is supplied from the hypochlorous acid storage unit 7 to the hollow body via the delivery unit 8, the hypochlorous acid aqueous solution is supplied from the hollow structure of the hollow body. Hypochlorous acid penetrates to the outside. The hypochlorous acid release unit 6 refines the hypochlorous acid in the process of permeation of the hypochlorous acid, and releases the finely divided hypochlorous acid into the air in the air passage 4.

Specifically, as shown in FIG. 2, the hypochlorous acid release unit 6 is composed of a hollow body having a pipe-shaped flow path. The hypochlorous acid release section 6 is a surface substantially orthogonal to the flow of the air 4a at a position where the air 4a faces from the suction port 2 to the hypochlorous acid release section 6 (hereinafter, also referred to as a “plane blocking the air air passage 4”). It is laid in a meandering manner on the top. That is, the hypochlorous acid discharge unit 6 is provided as a whole substantially perpendicular to the air air passage 4. In addition, since it will be described in detail in another embodiment, it is not particularly illustrated here, but from the air passage wall of the air air passage 4 facing the delivery unit 8 toward the hypochlorous acid storage unit 7 side. A part of the hypochlorous acid release unit 6 is placed on the protruding shelf (see, for example, FIG. 4A). As a result, the hypochlorous acid release portion 6 is provided substantially perpendicular to the air air passage 4 as a whole. Then, in the hypochlorous acid release unit 6, the hypochlorous acid aqueous solution from the hypochlorous acid storage unit 7 supplied via the delivery unit 8 flows through the inside of the hollow body.

More specifically, the hypochlorous acid release unit 6 has its starting end connected to a delivery unit 8 communicating with a pipe 10 located on the lower side of the hypochlorous acid storage unit 7 and blocks the air air passage 4. It is laid in a meandering manner on the surface. Then, the hypochlorous acid release unit 6 extends upward from one surface toward a surface blocking another air air passage 4 on the upstream side of the air air passage 4, and blocks the other air air passage 4. The surface is also meandered and laid. The end of the hypochlorous acid release unit 6 is connected to a pipe 10 located on the upper side of the hypochlorous acid storage unit 7, and the hypochlorous acid aqueous solution that has circulated inside the hollow body is hypochlorous acid. It is returned to the storage unit 7. That is, the hypochlorous acid release unit 6 circulates the hypochlorous acid aqueous solution of the hypochlorous acid storage unit 7. By returning the hypochlorous acid aqueous solution drawn from the lower side of the hypochlorous acid storage portion 7 to the upper side, even if the amount of the hypochlorous acid aqueous solution in the hypochlorous acid storage portion 7 is reduced, it will be relatively long. It can be circulated and used.

Further, the hypochlorous acid release unit 6 (hollow body constituting the hypochlorous acid release unit 6) is formed of a material having higher compatibility with hypochlorous acid than water. Here, compatibility refers to the similarity of molecular structures. The hypochlorous acid release unit 6 is formed of a material such as silicon resin, which is more compatible with hypochlorous acid than water molecules. Therefore, hypochlorous acid is more easily permeated from the inside to the outside of the hollow structure of the hollow body constituting the hypochlorous acid release portion 6 than water. That is, hypochlorous acid is preferentially released from the outer surface of the hypochlorous acid discharging portion 6 (the surface on the air air passage 4 side) to the air air passage 4.

The amount of hypochlorous acid released to the outer surface of the hypochlorous acid release unit 6 (the surface on the air air passage 4 side) can be adjusted by the following measures.

(A) Change the thickness of the film of the hollow body of the hypochlorous acid release part 6.

(B) Change the shape of the hypochlorous acid release unit 6 exposed to the air passage 4. For example, the diameter of the hollow body of the hypochlorous acid discharging portion 6 may be increased, or a hollow body structure having a rectangular parallelepiped cross section may be used.

(C) Change the material (compatibility) of the hypochlorous acid release unit 6. That is, the amount of hypochlorous acid released can be increased by using a material that is more compatible with hypochlorous acid, or the amount of hypochlorous acid released can be increased by using a material that is less compatible with hypochlorous acid. The amount may be reduced.

With the above configuration, in the space purification device 1, when the delivery unit 8 is operated, the hypochlorous acid aqueous solution stored in the hypochlorous acid storage unit 7 is sent to the inside of the hypochlorous acid discharge unit 6. The hypochlorous acid aqueous solution sent into the hypochlorous acid release unit 6 permeates the wall surface of the hypochlorous acid release unit 6 (hollow body constituting the hypochlorous acid release unit 6) and penetrates the outer surface (air). After penetrating into the air passage 4 side), it is discharged into the air air passage 4. As a result, when the air 4a sucked from the suction port 2 comes into contact with or passes through the hypochlorous acid discharging portion 6, the hypochlorous acid is taken into the air 4a, and the air 4a containing the hypochlorous acid is blown out. It will be blown out from 3 to the target space.

At this time, since the hypochlorous acid release unit 6 is formed of a material that is more compatible with hypochlorous acid than water molecules, that is, has higher compatibility with hypochlorous acid than water, hypochlorous acid. Hypochlorous acid preferentially permeates the outer surface of the release unit 6 and is released.

That is, in the space purification device 1, gaseous hypochlorous acid is released from the hypochlorous acid discharge unit 6, but humidification is not performed, so that the air 4a sucked from the suction port 2 is not humidified. Air 4a containing hypochlorous acid can be blown out from the outlet 3.

Further, the space purification device 1 according to the present embodiment has a configuration in which the hypochlorous acid release unit 6 is provided perpendicular to the air air passage 4 (see FIG. 2), but the hypochlorous acid release unit 6 is provided with air air. It may be provided parallel to the road 4 or at a predetermined angle. As a result, the area in which the hypochlorous acid discharge portion 6 and the air 4a are in vertical contact with each other is reduced, so that it is possible to prevent an increase in the pressure loss in the air air passage 4. In addition, the degree of freedom in designing the hypochlorous acid release unit 6 is improved.

Further, in order to finely adjust the amount of hypochlorous acid released according to the usage status of the space purification device 1, the space purification device 1 may be modified as follows. That is, the relationship between the pressure in the hypochlorous acid release section 6 and the release amount is obtained in advance. The space purification device according to this deformation includes a detection unit (not shown) for detecting the pressure in the hypochlorous acid release unit 6 and a control unit 11 (for example, FIG. 3) for varying the output of the delivery unit 8. The output of the sending unit 8 may be controlled by the control unit 11. That is, the control unit 11 of the space purification device related to this deformation applies a pressure corresponding to the desired amount of hypochlorous acid released to the hypochlorous acid aqueous solution stored in the hypochlorous acid storage unit 7 to hypochlorous acid. The delivery unit 8 may be controlled so as to deliver to the chlorite release unit 6.

(Embodiment 2)
The space purification device 1a according to the second embodiment of the present disclosure is configured so that the temperature of the hypochlorous acid aqueous solution stored in the hypochlorous acid storage unit 7 can be adjusted so that the temperature of the target space does not decrease. This is different from the space purification device 1 according to the first embodiment. Other than this, the configuration of the space purification device 1a is the same as that of the space purification device 1 according to the first embodiment. Hereinafter, the contents already explained in the first embodiment will be omitted again as appropriate, and the points different from the first embodiment will be mainly described.

The space purification device 1a according to the second embodiment of the present disclosure will be described with reference to FIG. FIG. 3 is a schematic view of the space purification device 1a according to the second embodiment of the present disclosure.

As shown in FIG. 3, in addition to the configuration of the space purification device 1 according to the first embodiment, the space purification device 1a includes a suction temperature detection unit 12, a blowout temperature detection unit 13, a temperature control unit 14, and a control unit. 11 and.

The suction temperature detection unit 12 is installed near the suction port 2 in the air air passage 4 and detects the temperature of the air 4a sucked from the suction port 2. Then, the suction temperature detection unit 12 outputs information (signal) regarding the detected temperature of the air 4a to the control unit 11.

The outlet temperature detection unit 13 is installed in the vicinity of the outlet 3 in the air air passage 4 and detects the temperature of the air 4a blown out from the outlet 3. Then, the blowout temperature detection unit 13 outputs information (signal) regarding the detected temperature of the air 4a to the control unit 11.

The temperature control unit 14 is installed at the bottom of the hypochlorous acid storage unit 7 and regulates the temperature of the hypochlorous acid aqueous solution sent from the hypochlorous acid storage unit 7.

The control unit 11 is installed in the housing 9 and controls the operation of the temperature control unit 14. The control unit 11 is connected to each of the suction temperature detection unit 12, the outlet temperature detection unit 13, and the temperature control unit 14 by wire or wirelessly. The control unit 11 has a computer system having a processor and a memory. Then, when the processor executes the program stored in the memory, the computer system functions as the control unit 11. The program executed by the processor is assumed to be pre-recorded in the memory of the computer system here, but may be recorded in a non-temporary recording medium such as a memory card and provided, or a telecommunications line such as the Internet. May be provided through.

Further, the control unit 11 has a water temperature control unit 15, and determines the operation of the temperature control unit 14 based on each signal output from each of the suction temperature detection unit 12 and the blowout temperature detection unit 13.

The water temperature adjusting unit 15 operates the temperature adjusting unit 14 so that the temperature detected by the suction temperature detecting unit 12 and the temperature detected by the blowing temperature detecting unit 13 are at least equal to each other. That is, the control unit 11 determines the operation of the temperature control unit 14 by the water temperature control unit 15.

In the space purification device 1a, when the operation of the blower unit 5 is started, the air 4a in the room (target space) is sucked from the suction port 2, and the sucked air 4a flows in the air air passage 4 and hypochlorous acid. It comes into contact with the hypochlorous acid that has penetrated the release part 6. At this time, the heat of vaporization is taken from the air 4a due to the volatilization of hypochlorous acid, and the blowing temperature detecting unit 13 may detect a temperature lower than the temperature detected by the suction temperature detecting unit 12.

Therefore, the space purification device 1a determines the operating amount of the temperature control unit 14 from this temperature difference by the water temperature control unit 15, and adjusts the temperature of the hypochlorous acid in the hypochlorous acid storage unit 7. That is, the control unit 11 (water temperature control unit 15) controls the temperature control unit 14 so as to raise the temperature of the hypochlorous acid aqueous solution sent from the hypochlorous acid storage unit 7 so that this temperature difference disappears. ..

The space purification device 1a can make the temperature detected by the outlet temperature detection unit 13 equal to the temperature detected by the suction temperature detection unit 12 by the operation of the temperature control unit 14. That is, the space purification device 1a reduces the temperature of the air 4a containing hypochlorous acid blown out from the outlet 3 (the temperature decrease that occurs when the hypochlorous acid is released into the air 4a flowing in the air air passage 4). Can be prevented. That is, since the space purification device 1a can prevent the temperature of the target space from decreasing, it is possible to prevent the user from being uncomfortable due to the decrease in room temperature.

As an example, the space purification device 1a according to the second embodiment is provided with the temperature control unit 14 in the hypochlorous acid storage unit 7, but is a pipe located on the lower side of the hypochlorous acid storage unit 7. It may be provided in the portion 10. That is, the installation location of the temperature control unit 14 is not limited as long as it controls the temperature of the hypochlorous acid aqueous solution sent from the hypochlorous acid storage unit 7.

That is, the hypochlorous acid release unit 6a is an air passage from the hypochlorous acid release unit 6a without increasing the hypochlorous acid concentration in the hypochlorous acid aqueous solution stored in the hypochlorous acid storage unit 7. It differs from the hypochlorous acid release unit 6 in that it is configured to increase the amount of hypochlorous acid released to 4. The other configurations are the same as those of the hypochlorous acid release unit 6 constituting the space purification device 1 according to the first embodiment. Hereinafter, the contents already explained in the first embodiment will be omitted again as appropriate, and the points different from the first embodiment will be mainly described.

The rotating body 22 is configured to be eccentric with respect to the rotating shaft 26 of the rotating body 22, and rotates in the flow direction 25 of the hypochlorous acid aqueous solution flowing in the hypochlorous acid discharging portion 6a.

Specifically, as shown in FIGS. 5A and 5B, the rotating body 22 has a shape having one protruding portion 24 on the outer peripheral portion of the circular flat plate, and is a rotating body having a distorted shape. Here, when the protruding portion 24 is in the position shown in FIG. 5A, for example, it comes into contact with the hypochlorous acid releasing portion 6a, but when it is in the position shown in FIG. 5B, for example, the hypochlorous acid Does not come into contact with the discharge portion 6a. That is, when the rotating body 22 rotates in the rotation direction 29, the protruding portion 24 comes into discontinuous contact with the hypochlorous acid releasing portion 6a, so that vibration can be applied to the hypochlorous acid releasing portion 6a.

Further, as described above, the hypochlorous acid release portion 6a is formed of a material such as silicon resin, which is more compatible with hypochlorous acid than water molecules. Therefore, the hypochlorous acid discharging portion 6a formed of a hollow body having a pipe-shaped flow path is easily deformed by an external force. Therefore, when the rotating body 22 rotates and the protruding portion 24 comes into contact with the hypochlorous acid releasing portion 6a, the hypochlorous acid releasing portion 6a is easily deformed. That is, since the rotation direction 29 of the rotating body 22 is the same as the flow direction 25 of the hypochlorous acid aqueous solution in the hypochlorous acid releasing part 6a, when the rotating body 22 rotates, the hypochlorous acid releasing part 6a Along with the deformation, the hypochlorous acid aqueous solution in the hypochlorous acid release portion 6a is extruded. Therefore, the space purification device according to the third embodiment can increase the flow speed of the hypochlorous acid aqueous solution in the hypochlorous acid release unit 6a.

With the above configuration, in the space purification device according to the third embodiment of the present disclosure, when the rotating body 22 rotates, the hypochlorous acid aqueous solution passing through the hypochlorous acid discharging portion 6a is pushed out in the flow direction 25. The passing speed can be increased. That is, the space purification device according to the third embodiment is miniaturized in the hypochlorous acid release unit 6a, and the amount of hypochlorous acid released into the air 4a flowing through the air air passage 4 can be increased. .. Therefore, the space purification device according to the third embodiment can easily disinfect and deodorize the hypochlorous acid by the hypochlorous acid without increasing the hypochlorous acid concentration in the hypochlorous acid aqueous solution of the hypochlorous acid storage unit 7. Can be improved.

Further, in the space purification device according to the third embodiment, when the rotating body 22 rotates, the hypochlorous acid release unit 6a vibrates. Therefore, in the space purification device according to the third embodiment, hypochlorous acid is more easily permeated into the hollow body constituting the hypochlorous acid release unit 6a, and the hypochlorous acid released from the hollow body into the air 4a. The amount of acid can be further increased.

The protruding portions 24 constituting the rotating body 22 may be single or plural. Further, the rotating body 22 may be in contact with the hypochlorous acid discharging portion 6a by taking a shape such that a circle is partially raised like an egg shape.

It is different from the space purification device 1a according to the second embodiment. Other than this, the configuration of the space purification device 1b is the same as that of the space purification device 1a according to the second embodiment. Hereinafter, the contents already explained in the second embodiment will be omitted again as appropriate, and the points different from the second embodiment will be mainly described.

The space purification device 1b according to the fourth embodiment of the present disclosure will be described with reference to FIG. FIG. 6 is a schematic view of the space purification device 1b according to the fourth embodiment of the present disclosure.

Generally, hypochlorous acid exists in an equilibrium state between "hypochlorous acid" and "hypochlorite ion" in an aqueous solution of hypochlorous acid. The equilibrium state abundance ratio is determined by the hydrogen ion concentration index (pH) in the hypochlorous acid aqueous solution.

The space purification device 1b changes the hydrogen ion concentration index (pH) of the hypochlorous acid aqueous solution in the hypochlorous acid storage portion 7 to change the abundance ratio of the hypochlorous acid in the hypochlorous acid aqueous solution in the equilibrium state. The amount of hypochlorous acid released from the hypochlorous acid discharging unit 6 is controlled in a short time by changing the above.

Specifically, as shown in FIG. 6, the space purification device 1b includes a concentration detection unit 27 and a concentration adjustment unit 28 in addition to the configuration of the space purification device 1a according to the second embodiment.

The concentration detection unit 27 is installed at the bottom of the hypochlorous acid storage unit 7 and measures and detects the hydrogen ion concentration index of the hypochlorous acid aqueous solution. The concentration detection unit 27 can also be said to be a pH detection unit. Since a known technique may be used for the detection means in the concentration detection unit 27, the description thereof will be omitted. Then, the concentration detection unit 27 outputs information (signal) regarding the detected hydrogen ion concentration index of the hypochlorous acid aqueous solution to the control unit 11. That is, the space purification device 1b is provided in the hypochlorous acid storage unit 7, detects the hydrogen ion concentration index of the hypochlorous acid aqueous solution, and controls the signal regarding the detected hydrogen ion concentration index of the hypochlorous acid aqueous solution. A concentration detection unit 27 that outputs to 11 is provided. The concentration detection unit 27 may be installed in the hypochlorous acid storage unit 7 and does not necessarily have to be at the bottom, but the amount of the hypochlorous acid aqueous solution in the hypochlorous acid storage unit 7 is reduced. It is preferable that it is at the bottom because it can function even if it comes.

The concentration adjusting unit 28 is installed at the bottom of the hypochlorous acid storage unit 7 and adjusts the hydrogen ion concentration index of the hypochlorous acid aqueous solution stored in the hypochlorous acid storage unit 7. The concentration detection unit 27 can also be said to be a pH detection unit. More specifically, the concentration adjusting unit 28 prepares a hydrogen ion concentration index adjusting agent (for example, for example) with respect to the hypochlorous acid aqueous solution stored in the hypochlorous acid storage unit 7 based on the control signal from the control unit 11. Dilute hydrochloric acid, phosphate buffer, sodium hydroxide, sodium hypochlorite) are added. That is, the space purification device 1b is provided in the hypochlorous acid storage unit 7, and adjusts the hydrogen ion concentration index of the hypochlorous acid aqueous solution by adding a hydrogen ion concentration index adjusting agent to the hypochlorous acid aqueous solution. A concentration adjusting unit 28 is provided. The hydrogen ion concentration index adjusting agent is preferably an aqueous solution having a predetermined concentration, but is not limited to a liquid form, and may be a solid form such as a tablet. Further, the hydrogen ion concentration index adjusting agent may be a single type or a mixed state of a plurality of types.

The control unit 11 controls the operation of the concentration adjusting unit 28 to add the hydrogen ion concentration index adjusting agent to the hypochlorous acid aqueous solution based on the signal from the concentration detecting unit 27 regarding the hydrogen ion concentration index. The control unit 11 is connected to each of the concentration detection unit 27 and the concentration adjustment unit 28 by wire or wirelessly. The control unit 11 adds an amount of the hydrogen ion concentration index adjusting agent that becomes a predetermined set value (target pH value) based on the information (signal) regarding the hydrogen ion concentration index of the hypochlorous acid aqueous solution from the concentration detection unit 27. Is calculated, and the operation of adding the hydrogen ion concentration index adjusting agent by the concentration adjusting unit 28 is determined. More specifically, the control unit 11 controls the concentration adjusting unit 28 so as to add the calculated addition amount of the hydrogen ion concentration index adjusting agent by outputting the control signal to the concentration adjusting unit 28. For example, when the hydrogen ion concentration index adjuster is a liquid, the concentration adjusting unit 28 controls the opening time of the inlet of the hydrogen ion concentration adjusting agent storage unit to adjust the hydrogen ion concentration index to the hypochlorous acid aqueous solution. Add the agent. When the hydrogen ion concentration index adjuster is a powder or a solid substance such as a tablet, the concentration adjusting unit 28 controls to open the inlet of the hydrogen ion concentration adjusting agent storage unit (not shown). A hydrogen ion concentration index regulator is added to the hypochlorous acid aqueous solution.

With the above configuration, the space purification device 1b can change the abundance ratio of free hypochlorous acid in the hypochlorous acid aqueous solution in the hypochlorous acid storage portion 7. Therefore, the space purification device 1b can change the miniaturization rate of hypochlorous acid that permeates the hollow body in the hypochlorous acid release unit 6, and releases hypochlorous acid from the hypochlorous acid release unit 6. It becomes possible to control the amount.

For example, when a hydrogen ion concentration index adjuster (for example, dilute hydrochloric acid or phosphate buffer) is added so as to lower the hydrogen ion concentration index in the hypochlorous acid aqueous solution, hypochlorous acid in the hypochlorous acid aqueous solution is added. Hypochlorous acid can be increased. Therefore, in the space purification device 1b, the rate of miniaturization of hypochlorous acid penetrating the hollow body increases, so that the amount of hypochlorous acid released from the hypochlorous acid release unit 6 can be increased.

On the other hand, when a hydrogen ion concentration index adjuster (for example, sodium hydroxide or sodium hypochlorite) is added so as to increase the hydrogen ion concentration index in the hypochlorous acid aqueous solution, hypochlorous acid is added. Hypochlorous acid in an aqueous acid solution can be reduced. Therefore, in the space purification device 1b, the rate of miniaturization of hypochlorous acid penetrating the hollow body is reduced, so that the amount of hypochlorous acid released from the hypochlorous acid release unit 6 can be reduced.

Therefore, the space purification device 1b controls the amount of hypochlorous acid released into the target space by adjusting the hydrogen ion concentration index in the hypochlorous acid aqueous solution in the hypochlorous acid storage portion 7. Can be done. That is, the space purification device 1b can control the amount of hypochlorous acid released into the target space without producing new hypochlorous acid or diluting the hypochlorous acid concentration by adding water. it can.

In the present embodiment, the concentration adjusting unit 28 is provided at the bottom of the hypochlorous acid storage unit 7 as an example. However, the concentration adjusting unit 28 may be provided on the top surface side of the hypochlorous acid storage unit 7 so that the hydrogen ion concentration index adjusting agent naturally falls due to gravity. Further, the concentration adjusting unit 28 may have an opening on the wall surface of the housing 9 and may have a structure in which a drug (hydrogen ion concentration index adjusting agent) can be added from the outside. Further, the space purification device 1b further includes a stirring unit (for example, a rotor) on the bottom surface of the hypochlorous acid storage unit 7, and a hydrogen ion concentration index adjuster and hypochlorous acid in the hypochlorous acid storage unit 7. It may be configured to mix with an aqueous solution to increase the diffusion rate of the hydrogen ion concentration index adjuster.
