[0004] The inventors of the present application have newly recognized the following: Conventional sterilization devices widely release air containing hypochlorous acid into a space such as a living room, and therefore have sterilization and deodorization effects against bacteria and odors floating in the space, but have limited effectiveness against bacteria and odors attached to specific objects such as small items and fabrics (e.g., stuffed toys, toys, socks, gloves, etc.).

[Figure 2] FIG. 2 is a diagram showing a second state of the space purification device of FIG. [Figure 3] FIG. 3 is a block diagram of the space purification device of FIG. [Figure 4] FIG. 4 is a diagram showing the space purification device of FIG. 1 in a third state. DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. In the embodiments and modified examples, identical or equivalent components and members are designated by the same reference numerals, and redundant explanations will be omitted where appropriate. Furthermore, the dimensions of the members in each drawing are enlarged or reduced as appropriate to facilitate understanding. Furthermore, some members that are not important for explaining the embodiments in each drawing are omitted.

[0011] A space purification device 10 according to an embodiment of the present disclosure will be described with reference to the drawings. FIG. 1 is a diagram schematically illustrating the space purification device 10 in a state where the storage unit 7 is not connected to the air outlet 16. FIG. 2 is a diagram schematically illustrating the space purification device 10 in a state where the storage unit 7 is connected to the air outlet 16. The space purification device 10 is a device that emits air containing hypochlorous acid (hereinafter referred to as "functional air") toward a predetermined space 1. The functional air can have the function of sterilizing the air and reducing at least one of bacteria and viruses, and the function of deodorizing the air and reducing odors. The predetermined space 1 is not limited, but the predetermined space 1 in the example of FIG. 1 is a living room.

[0012] However, when functional air is released into the specified space 1, it has the effect of sterilizing and deodorizing (hereinafter referred to as "purification") bacteria and odorous components floating in the specified space 1, but the purification effect is limited to bacteria and odorous components attached to small items (stuffed toys, toys, socks, gloves, etc.) and fabrics. Therefore, the space purification device 10 is provided with a storage unit 7 for intensively purifying such small items and fabrics (hereinafter referred to as "specific items 78"). In other words, the space purification device 10 can intensively purify the specific items 78 by introducing functional air containing hypochlorous acid into the storage unit 7 that stores the specific items 78.

[0013] The space purification device 10 includes a main body case 12, a blower unit 4, a generator unit 5, a purifier unit 6, a storage unit 7, a determination unit 82, a humidity sensor 92, an odor sensor 93, a display unit 14, an intake side determination unit 84, and a control unit 8.

[0014] The main body case 12 is a box-shaped housing having an intake port 18 that draws in air from the specified space 1 and an exhaust port 16 that blows air into the specified space 1. As an example, the intake port 18 can be provided on the side of the main body case 12. As an example, the exhaust port 16 can be provided on the top surface of the main body case 12. The storage unit 7 can be connected to the exhaust port 16. When the storage unit 7 is connected to the exhaust port 16, the exhaust port 16 can send functional air to the storage space 72.

[0015] The main body case 12 is provided with a blower 4, a generator 5, a purifier 6, a determiner 82, a humidity sensor 92, an odor sensor 93, a display 14, and an intake-side determiner 84.

[0016] The blower 4 can send air drawn in through the intake port 18 to the outlet 16. The blower 4 can increase or decrease the amount of air it blows under the control of the controller 8. There are no limitations on the configuration of the blower 4, but the blower 4 in this example includes a sirocco fan driven by a motor. As an example, the blower 4 is provided downstream of the purifier 6 and upstream of the outlet 16 as an air flow path.

[0017] The generator 5 can generate hypochlorous acid by electrolyzing, for example, saline solution. The generator 5 can increase or decrease the amount of hypochlorous acid generated based on the control of the controller 8. By increasing the current passed through the generator 5, the amount of hypochlorous acid generated can be increased, and by decreasing the current, the amount of hypochlorous acid generated can be decreased.

[0018] The purifying unit 6 can generate functional air by adding hypochlorous acid generated in the generating unit 5 to the air drawn in through the suction port 18. As an example, an aqueous solution of hypochlorous acid is attached to a filter-like fiber structure, and the air drawn in through the suction port 18 is brought into contact with this fiber structure, thereby allowing the air to contain hypochlorous acid.

[0019] The storage unit 7 has a box shape that surrounds a storage space 72 that is narrower than the specified space 1 and can be removably connected to the air outlet 16. The storage unit 7 in this example has a housing 71, an air outlet connection part 75, and an air inlet connection part 76. The housing 71 is a box-shaped case that surrounds the storage space 72 and has an inlet 73 for introducing the functional air blown out from the air outlet 16 into the storage space 72, an outlet 74 for discharging the functional air introduced into the storage space 72, and an entrance / exit part 77 for putting in and taking out a specific object 78.

[0020] The storage unit 7 can be removably connected to the air outlet 16. That is, the storage unit 7 can be easily connected to and removed from the air outlet 16. The storage unit 7 has a state where it is connected to the air outlet 16 and a state where it is not connected. The air outlet connector 75 is a mechanism for connecting the storage unit 7 to the air outlet 16, and can connect the inlet 73 to the air outlet 16 when connected. The air outlet connector 75 may be configured to directly connect the inlet 73 to the air outlet 16. The air outlet connector 75 in this example connects the inlet 73 to the air outlet 16 via a tubular ventilation member (a hose, a pipe, a duct, etc.).

[0021] The suction port connection part 76 is detachably connected to the suction port 18. That is, the suction port connection part 76 can be easily connected to and detached from the suction port 18. When connected to the suction port 18, the suction port connection part 76 can deliver air discharged from the discharge port 74 of the storage part 7 to the suction port 18. As an example, the suction port connection part 76 is a tubular member having an inlet part 762 and an outlet part 764. The inlet part 762 is connectable to the discharge port 74, and the outlet part 764 is connectable to the suction port 18. The suction port connection part 76 may also be configured to directly connect the discharge port 74 to the suction port 18.

[0022] The humidity sensor 92 can detect the humidity in the specified space 1. The humidity sensor 92 may be provided outside the main body case 12, but in this example the humidity sensor 92 is provided inside the main body case 12 and arranged upstream of the purifier 6 so as to detect the humidity of the air drawn in through the air inlet 18. The humidity sensor 92 provides the detection result to the controller 8 as a humidity detection value H1.

[0023] The odor sensor 93 can detect odors. The odor sensor 93 may be provided outside the main body case 12 so as to detect odors in the specified space 1, but in this example the odor sensor 93 is provided inside the main body case 12 and arranged upstream of the purification unit 6 so as to detect odors in the air sucked in from the suction port 18. The odor sensor 93 provides the detection result to the control unit 8 as an odor detection value S1.

[0024] The display unit 14 can display the humidity in the specified space 1. The display unit 14 can display the humidity and other information based on the control of the control unit 8. The control unit 8 can cause the display unit 14 to display the humidity according to the humidity detection value H1 of the humidity sensor 92. As an example, the display unit 14 is disposed at the upper left on the front of the main body case 12. The display unit 14 can employ a display device based on known principles, such as an LCD or LED. The display on the display unit 14 may be a character display using an LCD or the like, or a level display based on the number and position of lit LEDs.

[0025] The determination unit 82 determines whether the air outlet connector 75 of the storage unit 7 is connected to the air outlet 16 or whether the air outlet connector 75 of the storage unit 7 is not connected to the air outlet 16. The determination unit 82 can employ various determination methods based on known principles, such as a switch determination using a limit switch or other switching device, determination based on the output of a Hall element capable of detecting a magnet and its magnetic flux, or determination based on the state of a switching damper in a bifurcated air passage. In this example, the determination unit 82 includes a magnet (not shown) provided in the air outlet connector 75 and a Hall element (not shown) provided in the air outlet 16, and determines whether the air outlet connector 75 is connected or not based on the level of the magnetic flux of the magnet detected by the Hall element. The determination unit 82 provides the determination result J1 to the control unit 8.

[0026] The suction-side determination unit 84 determines whether the suction port connection unit 76 is connected to the suction port 18 or whether it is not connected to the suction port 18. The suction-side determination unit 84 can employ various determination methods based on known principles, such as switch switching determination, determination using a magnet and a Hall element, or determination based on the state of a switching damper. In this example, the suction-side determination unit 84 includes a magnet (not shown) provided at the outlet 764 of the suction port connection unit 76 and a Hall element (not shown) provided at the suction port 18, and determines whether the state is connected or disconnected based on the level of magnetic flux from the magnet detected by the Hall element. The suction-side determination unit 84 provides the determination result K1 to the control unit 8.

[0027] The functional blocks of the space purification device 10 will be described. Figure 3 is a block diagram of the space purification device 10. Each functional block shown in Figure 3 can be realized in hardware by elements or mechanical devices such as a computer CPU (Central Processing Unit), and in software by a computer program, etc., but here, functional blocks realized by the cooperation of these elements are depicted. Therefore, those skilled in the art who have read this specification will understand that these functional blocks can be realized in various ways by combining hardware and software.

[0028] The control unit 8 will be described with reference to Fig. 3. The control unit 8 includes an input unit 802, a generation control unit 804, an air blowing control unit 806, and a display control unit 808. The input unit 802 acquires the judgment result J1 of the judgment unit 82, the judgment result K1 of the suction side judgment unit 84, the detection result of the humidity sensor 92 (humidity detection value H1), and the detection result of the odor sensor 93 (odor detection value S1). The generation control unit 804 controls the amount of hypochlorous acid generated by the generation unit 5. The air blowing control unit 806 controls the amount of air blown by the air blowing unit 4. The display control unit 808 controls the display on the display unit 14.

[0029] The control unit 8 acquires one or more of the judgment result J1 of the judgment unit 82, the judgment result K1 of the suction-side judgment unit 84, the detection result of the humidity sensor 92 (humidity detection value H1), and the detection result of the odor sensor 93 (odor detection value S1), and can control the operations of the blower unit 4, the generation unit 5, and the display unit 14 according to the acquired results. In other words, the control unit 8 can change the operations of the blower unit 4, the generation unit 5, and the display unit 14 based on the acquired results.

[0030] The space purification mode and spot purification mode will be described with reference to Figures 1 and 2. Figure 1 shows the space purification device 10 in the space purification mode, and Figure 2 shows the space purification device 10 in the spot purification mode. In the space purification mode, the space purification device 10 adds hypochlorous acid to air A1 drawn in through the intake port 18 in the purification unit 6 to generate functional air A2, and then releases this functional air A2 into a specified space 1 to purify the specified space 1. In the spot purification mode, the space purification device 10 sends the functional air A2 to the storage unit 7, where it purifies specific objects 78 stored in the storage unit 7, and then discharges the exhaust air from the exhaust port 74.

[0031] (First operation) A first operation of the space purification device 10 will be described with reference to FIGS. 1 and 2. The first operation enables the space purification mode and the spot purification mode. In the first operation, when the determination unit 82 determines the connected state, the space purification device 10 reduces the airflow rate of the air blower 4 compared to when the determination unit 82 determines the disconnected state. The air blower 4 operates at a first airflow rate in the disconnected state and at a second airflow rate in the connected state. The second airflow rate is smaller than the first airflow rate, and may be, for example, 20% to 80% of the first airflow rate. In this case, it is possible to avoid sending excessive hypochlorous acid to the storage space 72, which is smaller than the predetermined space 1.

[0032] Furthermore, in the first operation example, when the determination unit 82 determines that the space purification device 10 is in the connected state, the generation unit 5 generates a smaller amount of hypochlorous acid than when the determination unit 82 determines that the space purification device 10 is in the disconnected state. The generation unit 5 generates a first amount of hypochlorous acid in the disconnected state, and generates a second amount of hypochlorous acid in the connected state. The second amount of hypochlorous acid is smaller than the first amount of hypochlorous acid, and may be, for example, in the range of 20% to 80% of the first amount of hypochlorous acid. In this case, it is possible to avoid sending excessive hypochlorous acid to the storage space 72, which is smaller than the predetermined space 1.

[0033] (Second action) A second operation of the space purification device 10 will be described with reference to FIGS. 1 and 2. In the second operation, the airflow rate is controlled in space purification mode and not in spot purification mode. In the second operation, if the determination unit 82 determines that the space purification device 10 is in a disconnected state, the airflow rate of the air blower 4 is controlled in accordance with the humidity detection value H1 detected by the humidity sensor 92 that detects the humidity in the specified space 1. However, if the determination unit 82 determines that the space purification device 10 is in a connected state, the airflow rate is not controlled. In this case, fluctuations in the airflow rate to the storage space 72 due to fluctuations in humidity in the specified space 1 can be avoided. As an example, the airflow rate control may be such that the airflow rate of the air blower 4 is increased as the humidity detection value H1 detected by the humidity sensor 92 decreases.

[0034] (Third action) 1 and 2, a third operation of the space purification device 10 will be described. In the third operation, at least one of the airflow rate and the hypochlorous acid production rate is controlled in response to odor in the space purification mode, but no control is performed in response to odor in the spot purification mode. In the third operation, if the determination unit 82 determines that the space purification device 10 is in a disconnected state, the space purification device 10 controls at least one of the airflow rate of the air blower 4 and the hypochlorous acid production rate of the production unit 5 in response to the odor detection value S1 detected by the odor sensor 93. If the determination unit 82 determines that the space purification device 10 is in a connected state, the space purification device 10 does not control the airflow rate and / or the hypochlorous acid production rate in response to the odor detection value S1 detected by the odor sensor 93.

[0035] In this case, it is possible to avoid fluctuations in the amount of hypochlorous acid sent to the storage space 72 due to odor in the specified space 1. As an example, the air volume control may be a control that increases the air volume of the blower unit 4 as the odor detection value S1 detected by the odor sensor 93 increases, and the hypochlorous acid production amount control may be a control that increases the amount of hypochlorous acid produced by the production unit 5 as the odor detection value S1 detected by the odor sensor 93 increases.

[0036] (Fourth action) 1 and 2, a fourth operation of the space purification device 10 will be described. In the fourth operation, the humidity is displayed in space purification mode, but not in spot purification mode. In the fourth operation, if the determination unit 82 determines that the space purification device 10 is in a disconnected state, the display unit 14, which displays the humidity in the specified space 1, displays the humidity, but if the determination unit 82 determines that the space purification device 10 is in a connected state, the display unit 14 does not display the humidity detection value H1. In this case, in the disconnected state, the humidity in the specified space 1 can be displayed to the user, and in the connected state, the user can be informed that air is not being sent to the specified space 1.

[0037] The circulation purification mode will be described with reference to Figure 4. Figure 4 shows the space purification device 10 in the circulation purification mode. In the circulation purification mode, the space purification device 10 sends functional air A2 to the storage unit 7, purifies the specific objects 78 stored in the storage unit 7, and then discharges the functional air A2 from the exhaust port 74. The exhaust air A3 discharged from the exhaust port 74 is sucked in through the inlet 18 and is again enriched with hypochlorous acid in the purification unit 6 to generate functional air A2. In this way, by circulating the functional air A2 and the exhaust air A3, the specific objects 78 can be efficiently sterilized and deodorized.

[0038] (5th action) A fifth operation of the space purification device 10 will be described with reference to FIG. 4. The fifth operation is an operation for realizing the circulation purification mode. FIG. 4 is a diagram showing the third state of the space purification device 10. The fifth operation is a circulation purification mode in which air from the storage unit 7 is sent to the intake port 18. In the fifth operation, to realize the circulation purification mode, the intake port connector 76 is connected between the exhaust port 74 of the storage unit 7 and the intake port 18. Specifically, as shown in FIG. 4, the inlet portion 762 of the intake port connector 76 is connected to the exhaust port 74 of the storage unit 7, and the outlet portion 764 is connected to the intake port 18.

[0039] It is desirable to be able to sterilize and deodorize specific items 78, such as small items stored in the storage unit 7, to a desired level. Therefore, in the fifth operation, when the suction-side determination unit 84 determines that the space purification device 10 is in a connected state, the space purification device 10 causes the blower unit 4 to blow air until the odor detection value S1 detected by the odor sensor 93 falls below a threshold. In this case, the odor sensor 93 can detect the deodorizing state of the specific items 78, so by setting the threshold below a desired level, the specific items 78 can be deodorized to a desired level. Note that sterilization effect is often thought to be related to deodorization effect, and it can be expected that deodorization to a desired level will also approach the desired level.

[0040] (6th action) A sixth operation of the space purification device 10 will be described with reference to FIG. 4. In the sixth operation, the airflow rate of the blower unit 4 is reduced in the circulation purification mode compared to the non-circulation purification mode. In the sixth operation, when the suction-side determination unit 84 determines the connected state, the space purification device 10 reduces the airflow rate of the blower unit 4 compared to when the suction-side determination unit 84 determines the disconnected state. In this case, circulation of an excessive amount of air can be avoided. Furthermore, circulation of an excessive amount of hypochlorous acid can be avoided. The blower unit 4 operates at a third airflow rate in the disconnected state, and at a fourth airflow rate in the connected state. The fourth airflow rate may be smaller than the third airflow rate, for example, in a range of 20% to 80% of the third airflow rate. Alternatively, the third airflow rate may be the second airflow rate. In this case, the fourth airflow rate may be smaller than the second airflow rate, for example, in a range of 20% to 80% of the second airflow rate.

[0041] (7th action) A seventh operation of the space purifying device 10 will be described with reference to FIG. 4. In the seventh operation, the amount of hypochlorous acid produced in the circulating purification mode is reduced compared to the non-circulating purification mode. In the seventh operation, when the suction-side determination unit 84 determines the connected state, the space purifying device 10 reduces the amount of hypochlorous acid produced by the generator 5 compared to when the suction-side determination unit 84 determines the disconnected state. In this case, excessive hypochlorous acid production can be avoided. The generator 5 produces a third amount of hypochlorous acid in the disconnected state and a fourth amount of hypochlorous acid in the connected state. The fourth amount of hypochlorous acid may be smaller than the third amount of hypochlorous acid, for example, in the range of 20% to 80% of the third amount of hypochlorous acid. Alternatively, the third amount of hypochlorous acid may be the second amount of hypochlorous acid. In this case, the fourth amount of hypochlorous acid produced may be smaller than the second amount of hypochlorous acid, for example, in the range of 20% to 80% of the second amount of hypochlorous acid.

[0042] An overview of one aspect of the present disclosure is as follows. A space purification device (10) of this aspect includes a main body case (12) having an inlet (18) for drawing in air from a predetermined space (1) and an outlet (16) for blowing air into the predetermined space (1), a blower unit (4) for sending the air drawn in through the inlet (18) to the outlet (16), a generator (5) for generating hypochlorous acid, a purifier unit (6) for generating functional air by adding the hypochlorous acid produced by the generator (5) to the air drawn in through the inlet (18), and a storage unit (7) surrounding a storage space (72) narrower than the predetermined space (1) and removably connectable to the outlet (16). The outlet (16) delivers the functional air to the storage space (72) when the storage unit (7) is connected to the outlet (16).

[0043] According to this embodiment, in a connected state in which the storage section 7 is connected to the air outlet 16, the specific objects 78 stored in the storage section 7 can be purified intensively.

[0044] As an example, the space purification device (10) includes a determination unit (82) that determines whether the storage unit (7) is in a connected state connected to the air outlet (16) or in a non-connected state where the storage unit (7) is not connected to the air outlet (16), and a control unit (8) that performs different control depending on the determination result (J1) of the determination unit (82).

[0045] For example, when the determining section (82) determines that the air conditioner is in the connected state, the control section (8) reduces the air volume of the blower section (4) compared to when the determining section (82) determines that the air conditioner is in the unconnected state.

[0046] As an example, when the determination unit (82) determines that the device is in the connected state, the control unit (8) reduces the amount of hypochlorous acid produced by the production unit (5) compared to when the determination unit (82) determines that the device is in the disconnected state.

[0047] As an example, the space purification device (10) includes a humidity sensor (92) that detects the humidity in the specified space (1). When the determination unit (82) determines that the space is disconnected, the control unit (8) controls the air volume of the air blower (4) in accordance with the humidity detection value (H1) detected by the humidity sensor (92). When the determination unit (82) determines that the space purification device (10) is connected, the control unit (8) does not control the air volume.

[0048] As an example, the air volume control is a control in which the air volume of the blower (4) is increased as the humidity detection value (H1) detected by the humidity sensor (92) decreases.

[0049] As an example, the space purification device (10) includes an odor sensor (93) that detects odor, and when the determination unit (82) determines that the device is in a disconnected state, the control unit (8) controls at least one of the air volume of the blower (4) and the hypochlorous acid production amount of the generator (5) in accordance with the odor detection value (S1) detected by the odor sensor (93), and when the determination unit (82) determines that the device is in a connected state, the control unit (8) does not control the air volume and / or the hypochlorous acid production amount in accordance with the odor detection value (S1) detected by the odor sensor (93).

[0050] As an example, the air volume control is a control for increasing the air volume of the blower (4) as the odor detection value (S1) detected by the odor sensor (93) increases, and the hypochlorous acid production amount control is a control for increasing the amount of hypochlorous acid produced by the production unit (5) as the odor detection value (S1) detected by the odor sensor (93) increases.

[0051] As an example, the space purification device (10) includes a display unit (14) that displays the humidity of the specified space (1), and the control unit (8) causes the display unit (14) to display the humidity detection value (H1) when the determination unit (82) determines that the device is in a disconnected state, and does not cause the display unit (14) to display the humidity detection value (H1) when the determination unit (82) determines that the device is in a connected state.

[0052] As an example, the space purification device (10) includes an inlet connection part (76) that can be detachably connected to the inlet (18) and that, when connected to the inlet (18, sends air from the storage part (7) to the inlet (18), and an inlet-side determination part (84) that determines whether the inlet connection part (76) is in a connected state, in which it is connected to the inlet (18), or in a non-connected state, in which the inlet connection part (76) is not connected to the inlet (18). When the inlet-side determination part (84) determines that the state is connected, the control part (8) controls the blower part (4) to blow air until the odor detection value (S1) detected by the odor sensor (93) becomes equal to or less than a threshold value.
