Description

[Technical Field]

[0001] The present disclosure relates to space purification technology, and in particular to a space purification device that sprays water containing hypochlorous acid water. [Background technology]

[0002] A spatial sterilization and deodorization device sprays fine water particles of a chemical agent, such as hypochlorous acid water, to sterilize a target area. For example, the liquid atomization chamber of the spatial sterilization and deodorization device releases water droplets from a hypochlorous acid solution stored in a water storage unit. The water droplets are blown by a blower unit through an air duct and released from an outlet into the target area (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] WO 20 / 158850 Summary of the Invention [Problem to be solved by the invention]

[0004] There is a possibility that some of the air containing atomized hypochlorous acid water may leak out of the liquid atomization chamber. Air containing high concentrations of hypochlorous acid may affect surrounding equipment.

[0005] The present disclosure has been made in consideration of these circumstances, and its purpose is to provide a space purification device that can suppress leakage of air containing hypochlorous acid. [Means for solving the problem]

[0006] To solve the above problems, an embodiment of the space purification device of the present disclosure includes a housing forming an outer shell, a partition wall dividing the housing into a first space and a second space and having a ventilation hole, a purification transport fan disposed in the first space and directing air drawn into the first space from outside the housing through the ventilation hole to the second space, and a micronization unit disposed in the second space and communicating with the ventilation hole, micronizing hypochlorous acid water into the air sent through the ventilation hole, and releasing the air containing the micronized hypochlorous acid water outside the housing. The partition wall has a ventilation hole communicating between the first space and the second space.

[0007] Any combination of the above components and conversion of the expressions of the present disclosure into methods, devices, systems, etc. are also valid aspects of the present disclosure. [Effects of the Invention]

[0008] According to the present disclosure, a space purification device that can suppress leakage of air containing hypochlorous acid can be provided. [Brief explanation of the drawings]

[0009] [Figure 1] 1 is a diagram showing the configuration of a space purification system according to an embodiment. [Figure 2] FIG. 2 is a diagram showing the configuration of the space purification device of FIG. DETAILED DESCRIPTION OF THE INVENTION

[0010] Before describing the specific embodiments of the present disclosure, an overview of the embodiments will be provided. This embodiment relates to a space purification system that adjusts humidity and sprays water containing a component that purifies the air (hereinafter referred to as "air purification component") into a room. The space purification system includes a space purification device that adjusts humidity and sprays water containing the air purification component. The air purification component may be, for example, hypochlorous acid, which has sterilizing or deodorizing properties. This sterilizes or deodorizes the room.

[0011] The space purification device includes a micronization unit that micronizes hypochlorous acid water and releases it into the air. As previously mentioned, some of the air containing the micronized hypochlorous acid water may leak from the micronization unit into the housing of the space purification device through drainage holes or the like provided in the micronization unit. The air that leaks into the housing may also leak outside the space purification device through gaps in the housing. For example, if the space purification device is installed in a relatively narrow space such as an attic and air containing hypochlorous acid is blown into the room through a duct, the hypochlorous acid-containing air leaking from the housing may increase the hypochlorous acid concentration in the attic space above the concentration in the room, potentially affecting the equipment installed in the attic. Furthermore, the hypochlorous acid-containing air leaking from the housing may affect the control board of the control unit of the space purification device attached to the housing. For example, these equipment and control units may deteriorate or malfunction.

[0012] Therefore, in this embodiment, the inside of the housing is divided into a first space and a second space by a partition wall, and the air drawn in by the purification transport fan located in the first space is sent to the atomization unit located in the second space and connected to the purification transport fan, and a vent hole connecting the first space and the second space is provided in the partition wall. As a result, negative pressure is generated in the first space due to the operation of the purification transport fan, so that air containing hypochlorous acid water leaking from the atomization unit to the second space is returned to the first space through the vent hole. Therefore, leakage of air containing hypochlorous acid outside the housing can be suppressed.

[0013] The examples described below each illustrate a preferred specific example of the present disclosure. Therefore, the numerical values, shapes, materials, components, component placement and connection configurations, steps (processes), and step order shown in the following examples are merely examples and are not intended to limit the present disclosure. Therefore, among the components in the following examples, components that are not described in the independent claims that represent the highest concept of the present disclosure are described as optional components. Furthermore, in each drawing, substantially identical components are designated by the same reference numerals, and redundant descriptions are omitted or simplified.

[0014] FIG. 1 shows the configuration of a space purification system 100 according to an embodiment. The space purification system 100 is a device that, when circulating air in an indoor space 62 (also referred to as "room"), adds atomized water and an air purification component to air (RA: Return Air) from the indoor space 62. The space purification system 100 sterilizes and deodorizes the indoor space 62 by supplying air (SA: Supply Air) that has circulated inside the system to the indoor space 62. Here, hypochlorous acid is used as the air purification component, and the water containing the air purification component is hypochlorous acid water.

[0015] 1, the space purification system 100 includes a space purification device 10, an operating device 70, a duct 64a, a duct 64c, a low-reactivity duct 67a, and a low-reactivity duct 67c. As an example, the space purification device 10 is installed in the ceiling of an indoor space 62. In this embodiment, the low-reactivity duct 67a and the low-reactivity duct 67c are collectively referred to as a duct 67.

[0016] Fig. 2 shows the configuration of the space purification device 10 of Fig. 1. As shown in Fig. 2, the space purification device 10 includes a housing 1, a purification air duct 5, a HEPA (High Efficiency Particulate Air) filter 11, a purification transport fan 12, a micronization unit 14, a partition wall 16, a hypochlorous acid water generation unit 19, and a control unit 41.

[0017] 2, the housing 1 forms the outer shell of the space purification device 10. The housing 1 has an air inlet 2a, an air inlet 2c, an air outlet 3a, and an air outlet 3c. In this embodiment, the air inlet 2a and the air inlet 2c are collectively referred to as an air inlet 2, and the air outlet 3a and the air outlet 3c are collectively referred to as an air outlet 3.

[0018] 2, the air inlet 2a and the air inlet 2c are arranged on one side surface of the housing 1. The air outlet 3a and the air outlet 3c are arranged on the other side surface of the housing 1 (the side surface opposite to the one side surface of the housing 1).

[0019] The air inlets 2a and 2c are intakes that respectively take in air 8a and air 8c outside the housing 1 obtained from the indoor space 62 into the space purification device 10. The air 8a and air 8c obtained from the indoor space 62 can also be called non-temperature-controlled air of the indoor space 62 that has not been temperature-controlled, or temperature-controlled air that has been temperature-controlled by an air conditioner or the like separately installed in the indoor space 62.

[0020] 1, air inlet 2a is connected to an indoor air inlet 65a provided on the ceiling or the like of indoor space 62 via duct 64a. Air inlet 2c is connected to an indoor air inlet 65c provided on the ceiling or the like of indoor space 62 via duct 64c. This allows air inlet 2a to draw air 8a from indoor space 62 into the space purification device 10 through indoor air inlet 65a. Air inlet 2c can draw air 8c from indoor space 62 into the space purification device 10 through indoor air inlet 65c.

[0021] Indoor air inlet 65c does not have to be provided. In this case, one end of duct 64a may be connected to indoor air inlet 65a, and the other end of duct 64a may be branched and connected to air inlet 2a and air inlet 2c.

[0022] The air outlet 3a is an outlet that discharges air 9a (SA) that has circulated inside the space purification device 10 into the indoor space 62. The air 9a contains atomized hypochlorous acid water. The air outlet 3c is an outlet that discharges air 9c (SA) that has circulated inside the space purification device 10 into the indoor space 62. The air 9c also contains atomized hypochlorous acid water.

[0023] 1, the air outlet 3a is in communication with an indoor air outlet 68a provided on the ceiling or the like of the indoor space 62 via a low-reactivity duct 67a. The air outlet 3c is in communication with an indoor air outlet 68c provided on the ceiling or the like of the indoor space 62 via a low-reactivity duct 67c. This allows the air outlet 3a to blow out air 9a that has circulated through the space purification device 10 from the indoor air outlet 68a toward the indoor space 62. The air outlet 3c is in communication with an indoor air outlet 68c toward the indoor space 62 via the indoor air outlet 68c.

[0024] Note that the air outlet 3a and the air outlet 3c are not distinguished from each other, and for example, the air outlet 3c may not be provided. In this case, one end of the low-reactivity duct 67a may be connected to the air outlet 3a, and the other end of the low-reactivity duct 67a may be branched and connected to the indoor air outlet 68a and the indoor air outlet 68c.

[0025] The low-reactivity duct 67a and the low-reactivity duct 67c are both ducts connected downstream of the purification air duct 5, and have inner walls made of a low-reactivity material that is poorly reactive with hypochlorous acid water. The low-reactivity material is, for example, a polyolefin-based material. The polyolefin-based material includes, for example, at least one of polyethylene and polypropylene.

[0026] As shown in FIG. 2, the cleaning airflow duct 5 is provided in the housing 1, and connects the intake 2 (the intake 2a and the intake 2c) with the outlet 3 (the outlet 3a and the outlet 3c).

[0027] The purification air duct 5 is an air duct through which both air 8a and air 8c flow. The purification air duct 5 can also be said to be an air duct through which a mixture of air 8a and air 8c flows. The purification air duct 5 is provided with a HEPA filter 11, a hypochlorous acid water generator 19, a purification conveying fan 12, and a micronization unit 14, in this order from upstream to downstream. Regarding the micronization unit 14, the purification air duct 5 passes through the space within the micronization unit 14. Upstream of the purification conveying fan 12, the hypochlorous acid water generator 19 is disposed adjacent to an intake port (not shown) of the purification conveying fan 12. Downstream of the purification conveying fan 12, the micronization unit 14 is disposed adjacent to an exhaust port (not shown) of the purification conveying fan 12.

[0028] The partition wall 16 is, for example, a plate-shaped member, and divides the inside of the housing 1 into a first space 17 and a second space 18. The first space 17 is an area where the HEPA filter 11, the purification transport fan 12, and the hypochlorous acid water generator 19 are arranged. The second space 18 is an area where the atomization unit 14 is arranged. The first space 17 corresponds to the portion of the purification air duct 5 that is upstream of the partition wall 16.

[0029] The partition wall 16 has a ventilation hole 16a and a ventilation hole 16b. The ventilation hole 16a connects the exhaust port (not shown) of the purification transport fan 12 with the intake port (not shown) of the atomization unit 14. The ventilation hole 16b connects the first space 17 with the second space 18. The opening area of ​​the ventilation hole 16b is smaller than the opening area of ​​the ventilation hole 16a. The opening area of ​​the ventilation hole 16b is larger than the opening area of ​​the gap (not shown) in the housing 1.

[0030] The HEPA filter 11 is an air filter that removes dirt, dust, etc. from the air that flows into the space purification device 10 and outputs purified air. The HEPA filter 11 is disposed adjacent to the intake ports 2a and 2c.

[0031] The purifying conveying fan 12 is a device for transporting air that has passed through the HEPA filter 11 along the purifying air duct 5 to the atomization unit 14. The purifying conveying fan 12 generates an air flow in the purifying air duct 5. The purifying conveying fan 12 draws air into the first space 17 through the suction port 2, and then blows the air into the duct 67 via the ventilation port 16a, the atomization unit 14, and the outlet 3. More specifically, the purifying conveying fan 12 is configured as a double-suction centrifugal fan. A known configuration can be adopted for the centrifugal fan. The purifying conveying fan 12 draws air through suction ports (not shown) provided on the left and right sides of the atomization unit 14, and transports the air to the atomization unit 14 through an outlet (not shown). A hypochlorous acid water generator 19 is disposed upstream of the suction port (not shown) provided on the left side of the purifying conveying fan 12.

[0032] In the purification transport fan 12, the air volume, that is, the rotation speed, is controlled in accordance with an output signal from the control unit 41. When the purification transport fan 12 is operated, air is sent to the micronization unit .

[0033] The hypochlorous acid water generator 19 is disposed upstream of the purification conveying fan 12 in the purification air duct 5. The hypochlorous acid water generator 19 includes an electrolytic cell 20, a brine tank 23, and a brine conveying pump 24. The hypochlorous acid water generator 19 dilutes brine (aqueous sodium chloride solution) stored in the brine tank 23 to a predetermined concentration in the electrolytic cell 20 and performs electrolysis to generate hypochlorous acid water of a predetermined concentration.

[0034] The brine tank 23 stores brine (aqueous sodium chloride solution) and supplies the brine to the electrolytic cell 20 via the brine transfer pump 24 in response to an output signal from the control unit 41. The electrolytic cell 20 stores the brine to be electrolyzed, supplied from the brine tank 23. In response to an output signal from the control unit 41, tap water is also supplied to the electrolytic cell 20 from a water pipe external to the space purification device 10 via the connection port 36 and the first solenoid valve 22. The supplied tap water and the brine are mixed, and brine of a predetermined concentration is stored. Electrodes (not shown) arranged in the electrolytic cell 20 electrolyze the brine by passing current in response to the output signal from the control unit 41, producing hypochlorous acid water of a predetermined concentration.

[0035] That is, the electrolytic cell 20 generates hypochlorous acid water by electrolyzing a chloride aqueous solution (e.g., salt water) as an electrolyte between a pair of electrodes. A general device is used for the electrolytic cell 20, and a detailed description thereof will be omitted. The electrolyte is not particularly limited as long as it is capable of generating hypochlorous acid water and contains even a small amount of chloride ions, and examples thereof include aqueous solutions in which sodium chloride, calcium chloride, magnesium chloride, or the like is dissolved as a solute. Hydrochloric acid is also acceptable. In this embodiment, an aqueous chloride solution (salt water) in which sodium chloride is added to water is used as the electrolyte.

[0036] The hypochlorous acid water supply unit 28 supplies hypochlorous acid water from the electrolytic bath 20 to the atomization unit 14 in response to an output signal from the control unit 41. The hypochlorous acid water supply unit 28 has a hypochlorous acid water transfer pump 29 and a hypochlorous acid water supply pipe 30. The hypochlorous acid water transfer pump 29 sends hypochlorous acid water from the electrolytic bath 20 to the hypochlorous acid water supply pipe 30 in response to an output signal from the control unit 41. The hypochlorous acid water supply pipe 30 is connected between the hypochlorous acid water transfer pump 29 and the atomization unit 14 through the vent 16b, and supplies hypochlorous acid water toward the atomization unit 14. Because the hypochlorous acid water supply pipe 30 is arranged through the vent 16b, there is no need to provide a dedicated opening in the partition wall 16 through which the hypochlorous acid water supply pipe 30 passes. This simplifies the configuration of the space purification device 10.

[0037] The water supply unit 32 supplies water to the atomization unit 14 in response to an output signal from the control unit 41. The water supply unit 32 has a second solenoid valve 33 and a water supply pipe 34. In response to an output signal from the control unit 41, the second solenoid valve 33 controls whether water supplied to the connection port 36 from a water pipe outside the space purification device 10 flows into the water supply pipe 34. The water supply pipe 34 is connected between the second solenoid valve 33 and the atomization unit 14, and supplies water toward the atomization unit 14. In the example of FIG. 2, an opening separate from the air vent 16b is provided in the partition wall 16, and the water supply pipe 34 passes through this opening, but the water supply pipe 34 may also pass through the air vent 16b.

[0038] In this way, the hypochlorous acid water and water are mixed in the atomization unit 14. The mixed water of the hypochlorous acid water and water can also be called hypochlorous acid water.

[0039] The atomization unit 14 is a unit for humidifying the air taken into the purification air duct 5, and during humidification, it adds hypochlorous acid as an air purification component along with atomized water to the air. As described above, the atomization unit 14 dilutes the hypochlorous acid water generated by the hypochlorous acid water generation unit 19 with water, atomizes the diluted hypochlorous acid water by centrifugal crushing, and releases it into the air. The atomized hypochlorous acid water is released outside the housing 1 with the liquid component evaporated.

[0040] The micronization section 14 has a centrifugal crushing unit and a mixing tank (not shown). The micronization section 14 has a centrifugal crushing type configuration in which the centrifugal crushing unit is rotated using a humidifying motor (not shown), and the hypochlorous acid water stored in the mixing tank is sucked up by centrifugal force, scattered, collided, and crushed in the surroundings (centrifugal direction), and the passing air is moistened.

[0041] The micronization unit 14 adjusts the humidification capacity (amount of humidification) by changing the rotation speed of the humidification motor in response to an output signal from the control unit 41. The amount of humidification can also be considered as the amount of air purification component added to the air. The control unit 41 controls the rotation speed of the centrifugal crushing unit based on the humidity measurement value detected by a humidity sensor (not shown).

[0042] A portion of the air saturated with hypochlorous acid water in the micronization unit 14 may leak from the micronization unit 14 into the second space 18. At this time, a negative pressure is generated in the first space 17 relative to the outside of the housing 1 and the second space 18 due to the airflow from the purification conveying fan 12. Therefore, the air 50 containing hypochlorous acid water that leaks from the micronization unit 14 into the second space 18 returns to the first space 17 through the vent 16b in the partition wall 16. Because the opening area of ​​the vent 16b is larger than the opening area of ​​the gaps in the housing 1, this also makes it easier for the air 50 leaking into the second space 18 to pass through the vent 16b rather than through the gaps in the housing 1. Air paths 52, 54 for returning from the second space 18 to the first space 17 are illustrated in FIG. 2. Therefore, the air 50 containing hypochlorous acid water that leaks into the second space 18 is less likely to leak out of the housing 1 through gaps in the housing 1. It is also possible to prevent the air 50 containing hypochlorous acid water that has leaked into the second space 18 from leaking to the control unit 41. Note that, since each member in the first space 17 is resistant to hypochlorous acid, there is no problem with the air 50 containing hypochlorous acid water returning to the first space 17 and circulating within the housing 1.

[0043] A first drain pan 44 is provided across the entire bottom surface of the hypochlorous acid water generator 19. The first drain pan 44 can temporarily store water leaking from the hypochlorous acid water generator 19, for example, when an abnormality occurs in the hypochlorous acid water generator 19 and water leakage occurs.

[0044] A second drain pan 46 is provided across the entire bottom surface of the micro-fining unit 14. The second drain pan 46 can temporarily store water leaking from the micro-fining unit 14, for example, when an abnormality occurs in the micro-fining unit 14 and water leakage occurs. The second drain pan 46 can also temporarily store mixed water drained from a drain outlet (not shown) of the micro-fining unit 14.

[0045] A drainage channel 39 that drains water received in the first drain pan 44 to the second drain pan 46 is connected to the first drain pan 44. The drainage channel 39 is arranged through the vent 16b. For example, the drainage channel 39 is inclined from the first drain pan 44 to the second drain pan 46, and water flows from the first drain pan 44 to the second drain pan 46 by utilizing the inclination. A drainage mechanism (not shown), such as a pump, is attached to the second drain pan 46 to drain the water accumulated inside to the outside of the space purification device 10.

[0046] Since the water received in the first drain pan 44 is drained to the second drain pan 46, and the water received in the second drain pan 46 is drained using a drainage mechanism, there is no need to provide a drainage mechanism in the first drain pan 44. Furthermore, since the drainage channel 39 passes through the vent 16b, there is no need to provide a dedicated opening in the partition wall 16 for the drainage channel 39 to pass through. This simplifies the configuration of the space purification device 10.

[0047] As shown in FIG. 1, an operating device 70 is installed on a wall surface of the indoor space 62. The operating device 70 has a user interface that can be operated by a user, and receives settings of a humidity setting value and an operation mode from the user. The operation modes include modes that specify the amount of hypochlorous acid in the air, such as a deodorizing mode, a sterilizing mode, and a normal mode. The operating device 70 includes a temperature and humidity sensor 72, which measures the temperature and humidity of the air in the indoor space 62. Known technology may be used to measure the temperature and humidity with the temperature and humidity sensor 72, and therefore a description thereof will be omitted here.

[0048] The operating device 70 is connected to the control unit 41 by wire or wirelessly, and transmits the humidity setting value, the humidity measurement value, and operation mode information to the control unit 41. This information may be transmitted all together, any two or more pieces of information may be transmitted together, or each piece may be transmitted separately.

[0049] The control unit 41 controls the purification conveying fan 12, the hypochlorous acid water generator 19, and the atomization unit 14. The control unit 41 controls the amount of hypochlorous acid water supplied to the atomization unit 14 and the amount of water supplied to the atomization unit 14, thereby controlling the concentration of hypochlorous acid in the mixed water from the atomization unit 14. More specifically, the control unit 41 controls the concentration of hypochlorous acid in the mixed water based on the required amount of humidification. For example, when a small amount of humidification is required, the control unit 41 increases the concentration of hypochlorous acid in the mixed water. This allows the required amount of hypochlorous acid to be met while maintaining appropriate humidity. On the other hand, when a large amount of humidification is required, if the concentration of hypochlorous acid in the mixed water is high, a large amount of hypochlorous acid will be supplied to the indoor space 62 along with a large amount of moisture, increasing the hypochlorous acid concentration in the indoor space 62. This will result in a strong hypochlorous acid odor in the indoor space 62, which may be unpleasant for users depending on the amount. Therefore, when the required amount of humidification is large, the concentration of hypochlorous acid in the mixed water can be reduced to increase the amount of humidification sent to the indoor space 62 while reducing the amount of hypochlorous acid. Thus, the control unit 41 can simultaneously control the amount of hypochlorous acid released and the humidity.

[0050] The control unit 41 may control the concentration of hypochlorous acid in the mixed water of the micronization unit 14 based on the required amount of hypochlorous acid. For example, when the required amount of humidification is small, the control unit 41 increases the concentration of hypochlorous acid in the mixed water as the required amount of hypochlorous acid increases. On the other hand, when the required amount of humidification is large, the control unit 41 decreases the concentration of hypochlorous acid in the mixed water as the required amount of hypochlorous acid increases.

[0051] The subject of the device, system, or method of the present disclosure includes a computer. The computer executes a program to realize the functions of the subject of the device, system, or method of the present disclosure. The computer includes, as its main hardware component, a processor that operates according to the program. The processor may be of any type, as long as it can realize the functions by executing the program. The processor may be composed of one or more electronic circuits, including a semiconductor integrated circuit (IC) or a large-scale integration (LSI). The electronic circuits may be integrated into a single chip or may be provided on multiple chips. The multiple chips may be integrated into a single device or may be provided on multiple devices. The program is recorded on a non-transitory recording medium, such as a computer-readable read-only memory (ROM), an optical disk, or a hard disk drive. The program may be pre-stored on the recording medium or may be supplied to the recording medium via a wide-area communication network, including the Internet.

[0052] According to this embodiment, the air 50 containing hypochlorous acid water that has leaked from the micronization unit 14 into the second space 18 returns to the first space 17 through the vent 16b of the partition wall 16 due to the negative pressure generated in the first space 17 by the air blown by the purification transport fan 12, so that the air 50 containing hypochlorous acid water that has leaked into the second space 18 is less likely to leak out of the housing 1 through gaps in the housing 1. This makes it possible to prevent the air 50 from affecting other devices and the control unit 41 installed above the ceiling, or causing them to deteriorate or malfunction.

[0053] The present disclosure has been described above based on examples. These examples are merely illustrative, and it will be understood by those skilled in the art that various modifications are possible in the combination of each component or each treatment process, and that such modifications are also within the scope of the present disclosure.

[0054] An outline of one embodiment of the present disclosure is as follows. A space purification device (10) according to one embodiment of the present disclosure includes a housing (1) forming an outer shell, a partition wall (16) that divides the interior of the housing (1) into a first space (17) and a second space (18) and has a ventilation opening (16a), a purification transport fan (12) arranged in the first space (17) that draws air into the first space (17) from outside the housing (1) and directs it through the ventilation opening (16a) to the second space (18), and a micronization unit (14) arranged in the second space (18) that communicates with the ventilation opening (16a) and micronizes hypochlorous acid water into the air sent through the ventilation opening (16a) and releases the micronized hypochlorous acid water-containing air outside the housing (1). The partition wall (16) has a ventilation opening (16b) that connects the first space (17) to the second space (18).
