Description

The present invention relates to space purification technology, and in particular to a space purification device that sprays water containing hypochlorous acid water.

The space purification device sprays fine water particles such as a medicinal agent, for example, hypochlorous acid water, to sterilize or deodorize a target area. For example, the liquid atomization chamber of the space purification device releases water droplets from the hypochlorous acid solution stored in the water storage section. The water droplets are blown through an air duct by the ventilation section and released from the outlet into the target area (see, for example, Patent Document 1).

WO 20/158850

However, in conventional space purification devices, when the amount of humidification required in the living space (humidification demand) is low (for example, during the mid-season and summer months in Japan), the amount of purification component (hypochlorous acid) released into the living space is small, making it difficult for the purification component to be released into the indoor space. In other words, with conventional space purification devices, if hypochlorous acid is supplied to the space based only on the amount of humidification, there is an issue in that it is not easy to increase the amount of purification component released into the indoor space (into the air) when the amount of humidification demand is low.

Therefore, the present invention aims to solve the above-mentioned conventional problems and provide a technology that makes it easier to adjust the amount of hypochlorous acid released into the air throughout the year.

In order to solve the above problems, the space purification device according to the present invention includes a micronization unit that adds hypochlorous acid to the air introduced from the living space by pumping the stored hypochlorous acid water and centrifugal crushing, and a control unit that controls the rotation operation during centrifugal crushing in the micronization unit. The control unit has a first control mode in which the rotation speed of the micronization unit is controlled based on the humidification demand amount for the living space and air containing hypochlorous acid is discharged into the living space , and a second control mode in which the rotation speed of the micronization unit is controlled based on the hypochlorous acid demand amount for the living space and air containing hypochlorous acid is discharged into the living space, and is characterized in that the first control mode is executed when the operation mode information transmitted from the air conditioner that adjusts the temperature of the air introduced from the living space to the micronization unit indicates heating operation, and the second control mode is executed when the operation mode information indicates cooling operation.

The present invention provides a technology that makes it easier to adjust the amount of hypochlorous acid released into the air throughout the year.

FIG. 1 is a schematic diagram of connections of an air conditioning system equipped with a space purification system in conjunction with a space purification device according to a first embodiment of the present invention. FIG. 2 is a schematic diagram showing the configuration of the spatial purification device. FIG. 3 is a control block diagram of the space purification device. FIG. 4 is a flow chart showing the processing operation in the control unit of the space purification device.

The spatial purification device according to the present invention includes a micronization unit that adds hypochlorous acid to air introduced from a living space by pumping stored hypochlorous acid water and centrifugal crushing, and a control unit that controls the rotation operation during centrifugal crushing in the micronization unit. The control unit has a first control mode that controls the rotation speed of the micronization unit based on the humidification demand for the living space, and a second control mode that controls the rotation speed of the micronization unit based on the hypochlorous acid demand for the living space, and executes the first control mode when operation mode information transmitted from an air conditioner that adjusts the temperature of air introduced from the living space to the micronization unit indicates heating operation, and executes the second control mode when the operation mode information indicates cooling operation.

According to this configuration, the first control mode is executed when the air conditioner is in heating operation, that is, when the relative humidity of the living space is low and the amount of humidification can be increased (e.g., winter in Japan), while the second control mode is executed when the air conditioner is in cooling operation, that is, when the humidification demand for the living space is low (e.g., summer in Japan). As a result, in winter in Japan, the finer unit executes a rotation operation based on the humidification demand, so that the amount of hypochlorous acid released into the living space can be easily adjusted according to the humidification demand. On the other hand, in summer in Japan, the finer unit executes a rotation operation based on the hypochlorous acid demand, so that the amount of hypochlorous acid released into the living space can be easily adjusted regardless of the humidification demand. In other words, in the space purification device, the first control mode and the second control mode are combined to execute the humidification purification operation, making it easier to adjust the amount of hypochlorous acid released into the air throughout the year.

In addition, in the spatial purification device according to the present invention, the control unit may execute the second control mode when the operation mode information of the air conditioner indicates heating operation and the temperature difference between the set temperature of the living space and the outside air temperature outside the living space is equal to or lower than the reference temperature. In this way, in a situation where the heating operation of the air conditioner is substantially stopped, the micronization unit executes a rotation operation based on the hypochlorous acid demand amount, so that the amount of hypochlorous acid released into the living space can be adjusted without creating a situation where it is difficult to release a predetermined amount of hypochlorous acid into the living space.

In addition, in the spatial purification device according to the present invention, the control unit may execute the second control mode when the operation mode information indicates that the air conditioning device is stopped. In this way, the micronization unit executes a rotation operation based on the hypochlorous acid demand during periods when air conditioning of the living space is not required (for example, intermediate periods that are the transitional period between summer and winter in Japan), so that the amount of hypochlorous acid released into the living space can be adjusted without creating a situation in which it is difficult to release a predetermined amount of hypochlorous acid into the living space.

In addition, in the spatial purification device according to the present invention, the control unit may switch to rotation operation in the first control mode if the humidity in the living space becomes equal to or higher than the reference humidity while rotation operation in the second control mode is being performed. This makes it possible to adjust the amount of humidification associated with the release of hypochlorous acid into the living space so that the living space is not over-humidified.

The following describes an embodiment of the present invention with reference to the drawings. Note that the following embodiment is an example of the present invention and does not limit the technical scope of the present invention.

(Embodiment 1)
First, an air conditioning system 20 including a space purification system 18 linked to a space purification device 40 according to the first embodiment of the present invention will be described with reference to Fig. 1. Fig. 1 is a schematic connection diagram of an air conditioning system 20 including a space purification system 18 linked to a space purification device 40 according to the first embodiment of the present invention.

As shown in FIG. 1, the air conditioning system 20 is configured with a heat exchange fan 4, multiple room dampers 5 (room dampers 5a, 5b, 5c, 5d), multiple circulation ports 6 (circulation ports 6a, 6b, 6c, 6d), multiple room exhaust ports 7 (room exhaust ports 7a, 7b, 7c, 7d), multiple room intake ports 8 (room intake ports 8a, 8b, 8c, 8d), an outdoor temperature sensor 16, a space purification system 18, an operation panel 50 (corresponding to an air conditioning controller), and a control unit 60 (see FIG. 3). The space purification system 18 is also configured with multiple transport fans 3 (transport fans 3a, 3b), an indoor temperature and humidity sensor 12, an air conditioning device (air conditioner) 13, an intake temperature and humidity sensor 14, a dust collection filter 17, and a space purification device 40.

The air conditioning system 20 is installed in a general house 1, which is an example of a building. The general house 1 has multiple (four in this embodiment) living rooms 2 (living rooms 2a, 2b, 2c, 2d), as well as at least one air-conditioned room 18a that is independent of the living rooms 2. Here, the general house 1 (house) is a residence provided as a place for residents to live private lives, and the living rooms 2 generally include a living room, dining room, bedroom, private room, and children's room. The living rooms 2 provided by the air conditioning system 20 may also include a toilet, bathroom, washroom, or dressing room.

In living room 2a, a circulation port 6a, a living room exhaust port 7a, a living room air intake port 8a, and an operation panel 50 are installed. In living room 2b, a circulation port 6b, a living room exhaust port 7b, and a living room air intake port 8b are installed. In living room 2c, a circulation port 6c, a living room exhaust port 7c, and a living room air intake port 8c are installed. In living room 2d, a circulation port 6d, a living room exhaust port 7d, and a living room air intake port 8d are installed.

A space purification system 18 is installed in the air-conditioned room 18a. The space purification system 18 is composed of a transport fan 3 (transport fans 3a, 3b), a room damper 5 (room dampers 5a, 5b, 5c, 5d), an indoor temperature and humidity sensor 12, an air conditioner 13, an intake temperature and humidity sensor 14, a space purification device 40, and a dust collection filter 17. More specifically, the space purification system 18 is arranged in the following order from the upstream side of the circulation path of the air flowing through the air-conditioned room 18a: the indoor temperature and humidity sensor 12, the air conditioner 13, the dust collection filter 17, the intake temperature and humidity sensor 14, the space purification device 40, the transport fan 3, and the room damper 5.

The air-conditioned room 18a refers to a space with a certain size where the indoor temperature and humidity sensor 12, air conditioner 13, dust collection filter 17, intake temperature and humidity sensor 14, space purification device 40, and transport fan 3 that make up the space purification system 18 can be placed, and where the air supplied to each room 2 can be controlled, but it is not intended as a living space, and does not essentially refer to a room where residents stay.

Air is introduced from the outside into the air-conditioned room 18a. In the air-conditioned room 18a, air (indoor air) transported from each room 2 through the circulation port 6 is mixed with outside air (outdoor air) taken in by the heat exchange fan 4 and heat exchanged. The air in the air-conditioned room 18a is controlled by the space purification system 18 (air conditioner 13 and space purification device 40) installed in the air-conditioned room 18a to adjust the temperature and to add an air purification component (hypochlorous acid) with humidity adjustment, and air to be transported to each room 2 is generated. The air treated by the space purification system 18 is transported to each room 2 as the supply air flow 10 by the transport fan 3.

Air from each room 2 is transported to the air-conditioned room 18a through the circulation port 6 as shown by the circulation flow 9, and is also heat-exchanged through the heat exchange fan 4 through the room exhaust port 7 as shown by the intake flow 11, before being exhausted outdoors. The air-conditioning system 20 performs ventilation using the first type of ventilation method by exhausting inside air (indoor air) from each room 2 through the heat exchange fan 4 while taking in outside air (outdoor air) indoors. The ventilation air volume of the heat exchange fan 4 can be set in multiple stages, and the ventilation air volume is set to meet the required ventilation volume stipulated by law.

The heat exchange fan 4 is configured with an internal supply fan (not shown) and an exhaust fan (not shown), and by operating each fan, ventilation is performed while exchanging heat between the inside air (indoor air) and the outside air (outdoor air). At this time, the heat exchange fan 4 transports the heat-exchanged outside air to the air-conditioning room 18a (space purification system 18).

The transport fan 3 is provided on the wall (bottom wall) of the air-conditioning room 18a. The air treated by the space purification system 18 is transported by the transport fan 3 through the transport duct from the room air supply port 8 to the room 2. More specifically, the air treated by the space purification system 18 is transported by the transport fan 3a to the rooms 2a and 2b located on the first floor of the general house 1, and by the transport fan 3b to the rooms 2c and 2d located on the second floor of the general house 1. The transport ducts connected to the room air supply port 8 of each room 2 are provided independently.

A portion of the air in each room 2 (rooms 2a to 2d) is transported to the air-conditioned room 18a through the circulation duct by the corresponding circulation port 6 (circulation port 6a to 6d). The circulation ducts connecting the air-conditioned room 18a to each room 2 may be provided independently, but multiple branch ducts that are part of the circulation duct may be merged midway to form a single circulation duct, which is then connected to the air-conditioned room 18a.

When transporting air from the transport fan 3 to each room 2, the room dampers 5 adjust the amount of air sent to each room 2 by adjusting the opening degree of the room dampers 5. More specifically, the room dampers 5a and 5b adjust the amount of air sent to rooms 2a and 2b located on the first floor. The room dampers 5c and 5d adjust the amount of air sent to rooms 2c and 2d located on the second floor.

As described above, each room circulation port 6 (circulation ports 6a to 6d) is an opening for transporting indoor air from each room 2 (rooms 2a to 2d) to the air-conditioned room 18a. Each room circulation port 6 draws in the air from each room 2 as a circulation flow 9.

As described above, each room exhaust vent 7 (room exhaust vents 7a to 7d) is an opening for transporting indoor air from each room 2 (rooms 2a to 2d) to the heat exchange fan 4. Each room exhaust vent 7 draws in air from each room 2 as an intake air flow 11.

As described above, each room air supply port 8 (room air supply ports 8a to 8d) is an opening for transporting air from the air-conditioned room 18a to each room 2 (rooms 2a to 2d). Each room air supply port 8 blows out air from the air-conditioned room 18a as an air supply flow 10.

The indoor temperature and humidity sensor 12 is installed upstream of the space purification system 18, and obtains the temperature and humidity (relative humidity) of the air sucked in from the living room 2 (living rooms 2a to 2d) and flowing into the air-conditioned room 18a (space purification system 18) as the living room temperature and living room humidity, respectively, and transmits these to the control unit 60.

The air conditioning device 13 corresponds to an air conditioner and controls the air conditioning of the space purification system 18. The air conditioning device 13 cools or heats the air in the air conditioning room 18a so that the temperature of the air in the air conditioning room 18a becomes the set temperature (air conditioning room target temperature). Here, the set temperature is set based on the result of calculating the required heat amount from the temperature difference between the target temperature (room target temperature) set by the user and the room temperature detected by the indoor temperature and humidity sensor 12. In this embodiment, the set temperature is set to a temperature at least higher than the target temperature in order to adjust the air temperature in each room 2 to the target temperature more quickly.

The dust collection filter 17 is a dust collection filter that captures particles suspended in the air introduced into the air-conditioned room 18a. The dust collection filter 17 captures particles contained in the air transported into the air-conditioned room 18a through the circulation port 6, thereby making the air supplied to the room by the transport fan 3 clean air. Here, the dust collection filter 17 is installed so as to block the air flow path in the area between the air conditioning device 13 and the space purification device 40.

The space purification device 40 is located downstream of the air conditioner 13 (and dust collection filter 17) in the air-conditioning room 18a, and when the humidity of the air in each room 2 (room humidity) is lower than the target humidity (room target humidity) set by the user, it humidifies the air in the air-conditioning room 18a so that the humidity becomes the target humidity. In addition, when humidifying, the space purification device 40 adds hypochlorous acid as an air purification component to the circulating air. Note that the humidity handled here is indicated as a relative humidity, but it may be handled as an absolute humidity by a predetermined conversion process. In this case, it is preferable to handle the entire handling in the air-conditioning system 20, including the humidity in the room 2, as an absolute humidity. Details of the space purification device 40 will be described later.

The intake temperature and humidity sensor 14 is a sensor that acquires the temperature and humidity (relative humidity) of the air whose temperature has been adjusted by the air conditioning device 13 in the space purification system 18 and transmits them to the control unit 60. More specifically, the intake temperature and humidity sensor 14 is installed downstream of the dust collection filter 17 in the space purification system 18, acquires the temperature and humidity of the air sucked into the space purification device 40, and transmits them to the control unit 60.

The outdoor temperature sensor 16 is installed in a location where it can detect the temperature of the outside air of the general house 1 (for example, the outside air inlet of the heat exchange fan 4, the outdoor unit of the air conditioner 13, the exterior wall of the general house 1, etc.), acquires the outside air temperature, and transmits it to the control unit 60.

The operation panel 50 is a terminal for inputting user input information (e.g., air volume, target temperature, target humidity, whether or not hypochlorous acid is added, the target supply level of hypochlorous acid, the heat exchange level of the heat exchange fan 4, etc.) related to the air conditioning system 20 (space purification system 18), and is connected to the control unit 60 wirelessly or via a wired connection so as to be able to communicate with the control unit 60. The target supply level of hypochlorous acid corresponds to the "hypochlorous acid demand" in the claims.

The control unit 60 is a controller that controls the entire air conditioning system 20. The control unit 60 is connected to each of the heat exchange fan 4, the transport fan 3, the room damper 5, the indoor temperature and humidity sensor 12, the air conditioning device 13, the intake temperature and humidity sensor 14, the outdoor temperature sensor 16, the space purification device 40, and the operation panel 50 so as to be able to communicate with them via wireless communication.

The control unit 60 also controls the air conditioner 13, the space purification device 40, the air volume of the transport fan 3, and the opening degree of the room damper 5 according to the temperature and humidity (room temperature and room humidity of room 2) acquired by the indoor temperature and humidity sensor 12, the set temperature and humidity (room set temperature and room set humidity) set in room 2, the temperature and humidity of the air in the air-conditioned room 18a acquired by the intake temperature and humidity sensor 14 (temperature and humidity of the air sucked into the space purification device 40), and the temperature acquired by the outdoor temperature sensor 16 (outdoor air temperature of the general house 1). The air volume of the transport fan 3 may be controlled individually for each fan.

As a result, the air conditioned by the space purification system 18 is transported to each room 2 at the air volume set in each transport fan 3 and each room damper 5. Therefore, the room temperature and room humidity of each room 2 are controlled to be the room target temperature and room target humidity. In addition, the supply amount of hypochlorous acid to each room 2 is controlled to be the target supply amount level.

Next, the configuration of the space purification device 40 will be outlined with reference to FIG. 2. FIG. 2 is a schematic diagram showing the configuration of the space purification device 40. Note that in FIG. 2, the configuration of the space purification device 40 is shown in functional blocks, but in reality, the space purification device 40 is housed in a single housing, and piping and the like are connected to the housing.

The space purification device 40 is located downstream of the air conditioner 13 in the air-conditioned room 18a, and is a device that humidifies the air in the air-conditioned room 18a by centrifugal water crushing while adding hypochlorous acid as an air purification component.

Specifically, the space purification device 40 is configured to include a micronization section 41, a hypochlorous acid water generation section 30, a hypochlorous acid water supply section 38, and a water supply section 48. The micronization section 41 is also configured to include a mixing tank 42, a centrifugal crushing unit 43, a water level sensor 44, and a purification air duct 49.

The micronization unit 41 is a unit for humidifying the air flowing through the purification air duct 49. When humidifying, the micronization unit 41 causes the flowing air to contain hypochlorous acid as an air purification component together with the micronized water. The micronization unit 41 can also be called a liquid micronization chamber or an air purification unit. More specifically, the micronization unit 41 micronizes the mixed water stored in the mixing tank 42 (hypochlorous acid water diluted by mixing hypochlorous acid water from the hypochlorous acid water generation unit 30 and water from the water supply unit 48) by centrifugal crushing, and causes the air flowing through the purification air duct 49 to contain the micronized water.

The mixing tank 42 is a tank that stores hypochlorous acid water in the micronization section 41, and can also be called a water storage section. In the mixing tank 42, hypochlorous acid water of a predetermined concentration supplied from the hypochlorous acid water supply section 38 described later and water supplied from the water supply section 48 described later are mixed in the tank, and mixed water consisting of diluted hypochlorous acid water is stored. In addition, although not specifically shown, a drain outlet is provided at the bottom of the mixing tank 42 for discharging the stored mixed water.

The centrifugal crushing unit 43 uses a humidification motor (not shown) to rotate the lift pipe 43a, sucking up the mixed water (hypochlorous acid water) stored in the mixing tank 42 with centrifugal force, scattering, colliding, and crushing it in the surroundings (centrifugal direction), and incorporating hypochlorous acid together with moisture into the air passing through the purification air duct 49.

The centrifugal crushing unit 43 changes the rotation speed of the humidification motor in response to an output signal from the control unit 60 to adjust the humidification capacity (amount of humidification). More specifically, the control unit 60 controls the rotation speed of the humidification motor and adjusts the amount of humidification based on the user's temperature and humidity settings and the target supply level setting of hypochlorous acid inputted through the operation panel 50, the temperature and humidity measurement values of the suction port of the space purification device 40 by the suction temperature and humidity sensor 14, and the temperature measurement value obtained by the outdoor temperature sensor 16. The amount of humidification can also be said to be the amount of hypochlorous acid added to the air flowing through the purification air duct 49.

The water level sensor 44 detects the water level of the mixed water stored in the mixing tank 42 and outputs the result to the control unit 60. More specifically, the water level sensor 44 has a water level sensor 44a that detects the water level of the mixed water stored in the mixing tank 42 when it is full, and a water level sensor 44b that detects the water level of the mixed water when it is reduced by a specified amount from the full water state.

The specified amount is set to the amount of hypochlorous acid water that can be produced in one electrolysis in the electrolytic cell 33 of the hypochlorous acid water generator 30.

The purification air duct 49 is an air duct for imparting hypochlorous acid as well as moisture to the air passing through the micronization section 41. An air intake and an air outlet (not shown) for the air passing through the purification air duct 49 are provided on the wall or ceiling of the micronization section 41. The purification air duct 49 is connected to the inside of the air-conditioning room 18a.

The micronization section 41 is composed of the above-mentioned components. In the micronization section 41, air that has passed through the dust collection filter 17 from the air conditioning room 18a is sucked into the inside, and hypochlorous acid is added to it along with moisture by the rotational action of the centrifugal crushing unit 43, and the air is blown back into the air conditioning room 18a.

Next, we will explain the hypochlorous acid water generator 30.

The hypochlorous acid water generator 30 is configured with a salt water tank 31, a salt water transport pump 32, an electrolytic cell 33, an electrode 34, and an electrolytic cell supply valve 35.

The saltwater tank 31 stores saltwater (aqueous sodium chloride solution) and supplies saltwater to the electrolytic cell 33 via the saltwater transport pump 32 in response to an output signal from the control unit 60. The electrolytic cell 33 stores the saltwater to be electrolyzed, which is supplied from the saltwater tank 31. In response to an output signal from the control unit 60, tap water is supplied to the electrolytic cell 33 from a water supply pipe 47 (described later) via an electrolytic cell supply valve 35, and the supplied tap water and saltwater are mixed to store saltwater of a predetermined concentration. The electrode 34 is disposed in the electrolytic cell 33 and electrolyzes the saltwater by passing electricity in response to an output signal from the control unit 60, producing hypochlorous acid water of a predetermined concentration.

In other words, the hypochlorous acid water generator 30 generates hypochlorous acid water by electrolyzing salt water as an electrolyte between a pair of electrodes constituting the electrodes 34 in the electrolytic cell 33. A general device is used for the hypochlorous acid water generator 30, so a detailed description will be omitted. Here, the electrolyte is an electrolyte capable of generating hypochlorous acid water, and is not particularly limited as long as it contains even a small amount of chloride ions. For example, an aqueous solution in which sodium chloride, calcium chloride, magnesium chloride, or the like is dissolved as a solute can be used. Hydrochloric acid can also be used. In this embodiment, an aqueous chloride solution (salt water) in which sodium chloride is added to water is used as the electrolyte.

Next, we will explain the hypochlorous acid water supply unit 38.

The hypochlorous acid water supply unit 38 supplies hypochlorous acid water from the electrolytic cell 33 of the hypochlorous acid water generation unit 30 to the mixing cell 42 of the micronization unit 41 in response to an output signal from the control unit 60. Specifically, the hypochlorous acid water supply unit 38 is configured to have a hypochlorous acid water transport pump 36 and a water supply pipe 37. The hypochlorous acid water transport pump 36 sends out hypochlorous acid water stored in the electrolytic cell 33 to the water supply pipe 37 in response to an output signal from the control unit 60. The water supply pipe 37 is connected between the hypochlorous acid water transport pump 36 and the mixing cell 42, and sends hypochlorous acid water from the electrolytic cell 33 toward the mixing cell 42.

Here, in the hypochlorous acid water supply unit 38, in order to ensure the concentration of hypochlorous acid water generated and stored in the hypochlorous acid water generation unit 30 (electrolytic cell 33), when supplying hypochlorous acid water from the electrolytic cell 33 to the mixing cell 42, the entire amount of hypochlorous acid water generated in the electrolytic cell 33 is supplied. Therefore, after the hypochlorous acid water is supplied, the electrolytic cell 33 is empty, and hypochlorous acid water will not start to be produced from a state in which hypochlorous acid water remains in the electrolytic cell 33.

Next, we will explain the water supply unit 48.

The water supply unit 48 supplies water (tap water) to the electrolytic cell 33 of the hypochlorous acid water generating unit 30 and to the mixing cell 42 of the micronization unit 41 in response to an output signal from the control unit 60. Specifically, the water supply unit 48 is configured to have an electrolytic cell supply valve 35, a mixing cell supply valve 45, and a water supply pipe 47. The electrolytic cell supply valve 35 controls whether or not water supplied from the water supply pipe 47 outside the hypochlorous acid water generating unit 30 through the strainer 46 is allowed to flow to the electrolytic cell 33 in response to an output signal from the control unit 60. The mixing cell supply valve 45 controls whether or not water supplied from the water supply pipe 47 outside the micronization unit 41 through the strainer 46 is allowed to flow to the mixing cell 42 in response to an output signal from the control unit 60. The water supply pipe 47 is connected to the electrolytic cell 33 via the electrolytic cell supply valve 35 and also to the mixing cell 42 via the mixing cell supply valve 45, and supplies water to the electrolytic cell 33 or the mixing cell 42.

The spatial purification device 40 may also be provided with a drain pan (not shown). The drain pan is disposed in the entire area below the micronization unit 41, the hypochlorous acid water generation unit 30, the hypochlorous acid water supply unit 38, and the water supply unit 48, and is a member that receives the water or hypochlorous acid water that falls from these. In this case, in addition to the drain pan, it is preferable to provide a drainage pump that drains the water or hypochlorous acid water in the drain pan into a drain drain when the water level in the drain pan reaches a predetermined value.

The space purification device 40 is composed of the above-mentioned components. In the space purification device 40, the water supplied from the water supply unit 48 and the hypochlorous acid water supplied from the hypochlorous acid water generation unit 30 are mixed. The mixed water of hypochlorous acid water and water mixed in this way can also be called hypochlorous acid water. The space purification device 40 sprays finely divided mixed water (hypochlorous acid water) by centrifugal crushing the mixed water stored in the mixing tank 42. The sprayed mixed water (hypochlorous acid water) is released into the air-conditioned room 18a with the liquid components evaporated.

In addition, if the air purification component hypochlorous acid is not added, depending on the user's settings, the space purification device 40 may operate as a humidifier to increase the humidity in the living room 2 by using only water as the mixed water to be centrifugally crushed in the micronization section 41.

Next, the control unit 60 will be described with reference to FIG. 3. FIG. 3 is a control block diagram of the space purification device 40. The control unit 60 controls the following processing operations of the space purification device 40: an operation related to the electrolysis process in the hypochlorous acid water generation unit 30 (electrolytic cell 33), an operation related to the supply process of hypochlorous acid water to the micronization unit 41 by the hypochlorous acid water supply unit 38 (first supply operation), an operation related to the supply process of water to the micronization unit 41 by the water supply unit 48 (second supply operation), and an operation related to the humidification purification process in the micronization unit 41. The control unit 60 has a computer system having a processor and a memory. The computer system functions as a controller by the processor executing a program stored in the memory. The program executed by the processor is pre-recorded in the memory of the computer system here, but it may be recorded on a non-temporary recording medium such as a memory card and provided, or it may be provided via a telecommunications line such as the Internet.

Specifically, as shown in FIG. 3, the control unit 60 includes an input unit 63, a processing unit 64, an output unit 65, a timing unit 61, and a memory unit 62.

<Operation regarding electrolysis process in hypochlorous acid water generation unit>
The control unit 60 causes the hypochlorous acid water generator 30 (electrolytic bath 33) to execute the following processes as operations related to the electrolysis process.

The control unit 60 receives information (operation stop information) regarding the stop of operation of the hypochlorous acid water supply unit 38 (hypochlorous acid water transport pump 36) and information regarding time (time information) from the timing unit 61 as a trigger for the electrolysis process of the electrolytic cell 33, and outputs these to the processing unit 64.

The processing unit 64 identifies control information based on the operation stop information from the hypochlorous acid water supply unit 38, the time information from the timer unit 61, and the setting information from the memory unit 62, and outputs the control information to the output unit 65. Here, the setting information includes information on the start or end time of hypochlorous acid water generation, information on the supply amount of tap water introduced into the electrolytic cell 33, information on the input amount of salt water in the salt water conveying pump 32, information on the electrolysis conditions (time, current value, voltage, etc.) in the electrode 34, information on the on/off operation of the electrolytic cell supply valve 35 in the water supply unit 48, and information on the on/off operation of the hypochlorous acid water conveying pump 36.

Here, the electrolysis conditions at the electrode 34 can be determined from the amount of tap water in the electrolytic cell 33, the salt water concentration, the electrolysis time, and the degree of deterioration of the electrode 34, and are set by creating an algorithm and stored in the memory unit 62.

Then, the output unit 65 outputs a signal (control signal) to each device (brine transport pump 32, electrode 34, electrolytic cell supply valve 35, hypochlorous acid water transport pump 36) based on the received control information.

In more detail, first, the salt water transfer pump 32 maintains a stopped state based on a signal from the output unit 65, and the hypochlorous acid water transfer pump 36 maintains a stopped state based on a signal from the output unit 65.

Then, the electrolytic cell supply valve 35 is opened based on a signal from the output unit 65. This starts the supply of tap water from the water supply pipe 47 to the electrolytic cell 33. After that, the electrolytic cell supply valve 35 is closed based on a signal from the output unit 65 that has received water level information (full) from the water level sensor 44a. This causes the electrolytic cell 33 to be supplied with tap water at the set supply amount.

Next, the saltwater transport pump 32 starts operating based on a signal from the output unit 65, transports a predetermined amount of saltwater to the electrolytic cell 33, and then stops. This causes the chloride ions in the saltwater to dissolve in the tap water, and the electrolytic cell 33 is in a state where an aqueous solution containing a predetermined amount of chloride ions (aqueous chloride solution) has been produced.

The electrode 34 then starts electrolysis of the chloride aqueous solution based on the signal from the output unit 65, produces hypochlorous acid water according to the set conditions, and stops. The hypochlorous acid water produced by the electrode 34 has, for example, a hypochlorous acid concentration of 100 ppm to 150 ppm (e.g., 120 ppm) and a pH of 7.0 to 8.5 (e.g., 8.0).

In this manner, the control unit 60 executes an electrolysis process in the electrolytic cell 33 of the hypochlorous acid water generator 30, and a predetermined concentration and amount of hypochlorous acid water is generated.

<Operation regarding supplying hypochlorous acid water to the micronization unit>
The control unit 60 executes the following process as an operation (first supply operation) related to the supply process of hypochlorous acid water to the micronization unit 41. In the following, the hypochlorous acid water supplied to the micronization unit 41 by the first supply operation is also referred to as "concentrated hypochlorous acid water."

The control unit 60 outputs a hypochlorous acid water supply request to the hypochlorous acid water generation unit 30 (hypochlorous acid water supply unit 36) based on information regarding the reduction time required for the mixed water to reach a state where a specified amount has been reduced, as a trigger for the supply process of hypochlorous acid water to the micronization unit 41.

Specifically, the processing unit 64 identifies control information based on information about the decrease time and the setting information from the memory unit 62, and outputs the control information to the output unit 65. Here, the setting information includes information about the timing of supplying hypochlorous acid water and information about the on/off operation of the hypochlorous acid water transport pump 36.

Then, the output unit 65 outputs a signal (control signal) to the hypochlorous acid water transport pump 36 of the hypochlorous acid water supply unit 38 based on the received control information.

The hypochlorous acid water conveying pump 36 operates based on a signal from the output unit 65. As a result, the hypochlorous acid water generating unit 30 starts supplying the hypochlorous acid water concentrate from the electrolytic cell 33 to the micronization unit 41 (mixing cell 42). Note that, in order to ensure the concentration of hypochlorous acid water stored in the electrolytic cell 33, when the hypochlorous acid water concentrate is supplied from the hypochlorous acid water generating unit 30 to the mixing cell 42, the entire amount of the hypochlorous acid water concentrate generated in the electrolytic cell 33 is supplied.

Then, the hypochlorous acid water conveying pump 36 stops based on a signal from the output unit 65 that receives information about time (the time required to supply the entire amount) from the timer unit 61. As a result, the hypochlorous acid water supply unit 38 supplies the hypochlorous acid water concentrate from the electrolytic cell 33 to the micronization unit 41 (mixing cell 42) at the set supply amount.

As described above, the control unit 60 performs a first supply operation in which the hypochlorous acid water supply unit 38 supplies the hypochlorous acid water concentrate from the hypochlorous acid water generation unit 30 (electrolytic cell 33) to the micronization unit 41.

<Operations related to supplying water to the micronization unit>
The control unit 60 executes the following process as an operation related to the process of supplying water to the microparticulation unit 41 (second supply operation).

The control unit 60 outputs a water supply request to the water supply unit 48 as a trigger for the water supply process to the micronization unit 41 based on information regarding the reduction time required for the mixed water to reach a state where a specified amount of the mixed water has been reduced.

Specifically, the processing unit 64 identifies control information based on information about the decrease time and the setting information from the memory unit 62, and outputs the control information to the output unit 65. Here, the setting information includes information about the timing of water supply and information about the on/off operation of the mixing tank supply valve 45.

Then, the output unit 65 outputs a signal (control signal) to the mixing tank supply valve 45 based on the received control information.

The mixing tank supply valve 45 operates based on a signal from the output unit 65. This causes the water supply unit 48 to start supplying water from the external water supply pipe via the water supply pipe 47 to the micronization unit 41 (mixing tank 42).

Then, the mixing tank supply valve 45 stops based on a signal from the output unit 65 that has received water level information (full water signal) from the water level sensor 44a of the micronization unit 41. This causes the water supply unit 48 to supply water from the water supply pipe 47 to the micronization unit 41 (mixing tank 42) until the set amount of water is reached.

In this manner, the control unit 60 causes the water supply unit 48 to execute a process of supplying water from the water supply pipe 47 to the micronization unit 41 as the second supply operation.

<Operations related to humidification and purification processing in the microfabrication section>
Next, the operation of the control unit 60 regarding the humidification and purification process in the microparticulation unit 41 will be described.

The input unit 63 receives user input information from the operation panel 50, temperature and humidity information (information on temperature and humidity) of the air in the living room 2 from the indoor temperature and humidity sensor 12, temperature and humidity information (information on temperature and relative humidity) of the air in the air-conditioned room 18a from the intake temperature and humidity sensor 14, outside air temperature information (information on temperature) from the outdoor temperature sensor 16, and water level information of the hypochlorous acid water (mixed water) in the mixing tank 42 from the water level sensor 44. The input unit 63 outputs each piece of received information to the processing unit 64.

The timing unit 61 outputs time information regarding the current time to the processing unit 64.

The memory unit 62 stores user input information received by the input unit 63 and information on the rotation speed in the centrifugal crushing unit relative to the temperature and relative humidity of the air flowing into the micronization unit 41 (information on the rotation speed based on the humidification requirement in the first control mode, and information on the rotation speed based on the hypochlorous acid requirement in the second control mode, etc.). The memory unit 62 outputs the various stored information to the processing unit 64 in response to a request from the processing unit 64.

The processing unit 64 receives various information from the input unit 63 (user input information, temperature and humidity information, outside air temperature information, and information on the requested amount of additional air purification components), time information from the timer unit 61, and various information from the memory unit 62 (rotation speed information). The processing unit 64 uses the various received information to identify control information related to the humidification and purification operation in the first control mode or the second control mode.

The first control mode is a mode for controlling the rotation speed of the micronization unit 41, which is determined based on the humidification demand for the living room 2. The first control mode is mainly executed when the relative humidity of the living room 2 is low and the amount of humidification can be increased (e.g., winter in Japan). More specifically, the first control mode is executed when the air conditioning device 13 is in heating operation and the temperature difference between the set temperature of the living room 2 (living room set temperature) and the outside air temperature acquired from the outdoor temperature sensor 16 is greater than the reference temperature. Here, the reference temperature is set to, for example, 6°C. The first control mode is set to a rotation speed in the range of, for example, 600 rpm to 4000 rpm, based on the humidity difference between the target humidity stored in the memory unit 62 and the humidity of the air in the living room 2 from the indoor temperature and humidity sensor 12 (e.g., absolute humidity).

In this embodiment, the micronization unit 41 controls the water stop state and the drain state of the hypochlorous acid water stored in the mixing tank 42 by the rotation of the lift pipe 43a. More specifically, in the micronization unit 41, the lift pipe 43a is arranged at a predetermined position directly above the drain outlet (not shown) of the mixing tank 42. When the humidification purification operation is started and the lift pipe 43a rotates, a vortex (not shown) is generated in the hypochlorous acid water of the mixing tank 42 inside the lift pipe 43a due to the centrifugal force of the rotation. Then, the lift pipe 43a forms a gap (not shown) that communicates between the tip opening of the lift pipe 43a and the drain outlet at the center of the vortex generated by the rotation. As a result, the gap blocks the drain outlet, and the hypochlorous acid water in the mixing tank 42 is prevented from flowing into the drain outlet. That is, in the micronization unit 41, during the humidification purification operation (while the water pumping pipe 43a is rotating), the water is stopped, and the hypochlorous acid water in the mixing tank 42 is prevented from being discharged from the drain. On the other hand, when the rotation of the water pumping pipe 43a is stopped, the vortex and the gap disappear, and the hypochlorous acid water in the mixing tank 42 flows into the drain. That is, in the micronization unit 41, by stopping the humidification purification operation (the rotation of the water pumping pipe 43a), the water is discharged, and the hypochlorous acid water in the mixing tank 42 can be discharged from the drain. For this reason, even if it is determined that humidification purification is not necessary, the rotation speed of the water pumping pipe 43a must be set to a minimum rotation speed (water stop rotation speed) or higher to maintain the water stop state of the micronization unit 41, and the lower limit rotation speed in the first control mode is set to 600 rpm.

The second control mode is a mode for controlling the rotation speed of the micronization unit 41, which is determined based on the amount of hypochlorous acid required for the living room 2. The second control mode is mainly executed during periods when the amount of humidification required for the living room 2 is low (e.g., mid-season and summer in Japan). More specifically, the second control mode is executed when any of the following three conditions (conditions 1 to 3) is satisfied. Here, the amount of hypochlorous acid required is the amount of hypochlorous acid to be supplied to the living room 2, and is set, for example, based on a parameter representing the target supply level of hypochlorous acid input by the user to the operation panel 50 as "high," "standard," or "low." The second control mode is set to a rotation speed in the range of, for example, 600 rpm to 4000 rpm, based on the target supply level of hypochlorous acid stored in the memory unit 62.

Condition 1: The air conditioning unit 13 is not in operation.

Condition 2: The air conditioning unit 13 is in cooling operation.

Condition 3: The air conditioning device 13 is in heating operation, and the temperature difference between the set temperature of room 2 (room set temperature) and the outside air temperature obtained from the outdoor temperature sensor 16 is equal to or less than the reference temperature.

The second control mode can also be considered a mode in which, when the humidification demand for the living room 2 is low, the humidification purification operation is performed at a rotation speed of the micronization unit 41 that is determined based on the hypochlorous acid demand, in preference to the rotation speed of the micronization unit 41 that is determined based on the humidification demand.

The processing unit 64 will now be described in detail.

The processing unit 64 determines the humidification demand required for the living room 2 based on the humidity difference between the target humidity stored in the memory unit 62 and the temperature and humidity information of the air in the living room 2 from the indoor temperature and humidity sensor 12 at regular intervals based on the time information from the timer unit 61. The processing unit 64 also determines the hypochlorous acid demand required for the living room 2 based on the target supply level of hypochlorous acid stored in the memory unit 62. The processing unit 64 then determines control information (humidification control information) related to the humidification purification operation operation based on the determined humidification demand and hypochlorous acid demand and the rotation speed information stored in the memory unit 62. The processing unit 64 then outputs a signal related to the determined control information to the output unit 65. The processing unit 64 also determines the operation related to the supply of hypochlorous acid water (first supply operation) and the operation related to the supply of water (second supply operation). The processing unit 64 then outputs a signal related to the determined control information to the output unit 65. The supply control information includes a hypochlorous acid water supply request signal and a water supply request signal.

The output unit 65 then outputs each of the received signals to the micronization unit 41, the hypochlorous acid water supply unit 38, and the water supply unit 48, respectively.

The hypochlorous acid water supply unit 38 receives a signal (a hypochlorous acid water supply request signal included in the supply control information) from the output unit 65, and performs an operation (first supply operation) related to the supply process of hypochlorous acid water to the mixing tank 42 of the micronization unit 41 described above at a predetermined supply timing based on the received signal. The water supply unit 48 also receives a signal (a water supply request signal included in the supply control information) from the output unit 65, and performs an operation (second supply operation) related to the supply process of water to the mixing tank 42 of the micronization unit 41 described above at a predetermined supply timing based on the received signal.

Then, the micronization unit 41 receives a signal from the output unit 65, and controls the rotation operation of the centrifugal crushing unit 43 based on the received signal. More specifically, the micronization unit 41 performs a humidification purification process on the air circulating inside (the purification air duct 49) by a rotation operation set based on the humidification demand amount in the first control mode or a rotation operation set based on the hypochlorous acid demand amount set in the second control mode. Thereafter, when the humidification purification process progresses and the amount of mixed water is reduced by a specified amount from the amount of water in the full water state (when water level information is acquired from the water level sensor 44b), the micronization unit 41 executes a first supply operation or a second supply operation to replenish the reduced specified amount.

Next, the rotation speed control operation of the micronization unit 41 in the control unit 60 of the space purification device 40 will be described with reference to FIG. 4. FIG. 4 is a flow chart showing the processing operation in the control unit 60 of the space purification device 40. Note that, in the following, the description of the water or hypochlorous acid water supply processing operation and the drainage processing operation performed during the humidification purification processing operation will be omitted.

First, when the humidification purification process is started, the control unit 60 acquires information about the operation mode (operation mode information) from the air conditioner 13 (step S01). Based on the acquired operation mode information, the control unit 60 determines whether the air conditioner 13 is stopped (step S02). If the result of the determination is that the air conditioner 13 is stopped (Yes in step S02), the control unit 60 determines that the above-mentioned condition 1 is satisfied and causes the micronization unit 41 to start the humidification purification operation in the second control mode (step S09). Note that in the humidification purification operation in the second control mode, the micronization unit 41 is set to a rotation speed (in the range of 600 rpm to 4000 rpm) specified based on the hypochlorous acid demand.

On the other hand, if the result of the judgment in step S02 is that the air conditioner 13 has not stopped operating, i.e., is in operation (No in step S02), the control unit 60 judges whether the air conditioner 13 is in heating operation or not based on the acquired operation mode information (step S03). Then, if the result of the judgment is that the air conditioner 13 is not in heating operation (No in step S03), the control unit 60 determines that the above-mentioned condition 2 is satisfied, i.e., that the air conditioner 13 is in cooling operation (step S04), and causes the micronization unit 41 to start humidification and purification operation in the second control mode (step S09).

On the other hand, if the result of the determination in step S03 is that the air conditioner 13 is in heating operation (Yes in step S03), the control unit 60 determines that the air conditioner 13 is in heating operation (step S05). Then, the control unit 60 calculates the temperature difference between the set temperature of room 2 (room set temperature) inputted through the operation panel 50 and the outside air temperature detected by the outdoor temperature sensor 16 (step S06). Based on the acquired temperature difference information, the control unit 60 determines whether the temperature difference is greater than the reference temperature (step S07). Then, if the result of the determination is that the temperature difference is not greater than the reference temperature, that is, the temperature difference is equal to or less than the reference temperature (No in step S07), it is determined that the above-mentioned condition 3 is satisfied, and the control unit 60 causes the microfabrication unit 41 to start humidification and purification operation in the second control mode (step S09).

On the other hand, if the result of the determination in step S07 is that the temperature difference is greater than the reference temperature (Yes in step S07), the control unit 60 causes the micronization unit 41 to start a humidification and purification operation in the first control mode (step S08). In the humidification and purification operation in the first control mode, the micronization unit 41 is set to a rotation speed (in the range of 600 rpm to 4000 rpm) that is controlled based on the humidification request amount.

Specifically, in steps S03 to S09, if the air conditioner 13 is in cooling operation, the humidification and purification operation is performed in the second control mode. On the other hand, when the air conditioner 13 is in heating operation and the room set temperature is 22°C and the outdoor temperature is 15°C, the temperature difference is 7°C, which is greater than the reference temperature (6°C), so the humidification and purification operation is performed in the first control mode. In contrast, when the air conditioner 13 is in heating operation and the room set temperature is 22°C and the outdoor temperature is 20°C, the temperature difference is 2°C, which is less than the reference temperature (6°C), so the humidification and purification operation is performed in the second control mode.

Then, the control unit 60 judges whether the time measured from the start time of the humidification purification operation by the micronization unit 41 in step S08 or step S09 has elapsed a predetermined time (step S10). If the result of the judgment is that the predetermined time has not elapsed (No in step S10), the control unit 60 continues the humidification purification operation by the micronization unit 41 (return to step S10). On the other hand, if the predetermined time has elapsed (Yes in step S10), the control unit 60 returns to step S01. Here, the predetermined time is an interval time for feedback control of humidification purification, and is set to, for example, 5 minutes.

In this manner, the space purification device 40 performs operations related to the humidification purification process using the micronization unit 41.

Next, we will explain each control (first control mode, second control mode) in the humidification and purification operation of the micronization unit 41.

As described above, the first control mode is executed in a period when the relative humidity in the living room 2 is low and the amount of humidification can be increased (e.g., winter in Japan). In such a period, the micronization unit 41 can release a predetermined amount of space purification component (hypochlorous acid) into the living room 2 in conjunction with the humidification purification operation (humidification operation). In other words, in such a period, when there is a request to release hypochlorous acid into the living room 2, the micronization unit 41 can easily adjust the amount of hypochlorous acid released into the living room 2 according to the requested amount of humidification by performing a rotation operation (humidification purification operation in the first control mode) based on the requested amount of humidification.

However, in the first control mode, the relative humidity of the air in room 2 is high during the intermediate seasons in Japan (e.g., the transition period between summer and winter, which corresponds to spring or autumn in Japan) and during the summer.
The required amount of humidification for the living room 2 may be determined to be low, or it may be determined that humidification is unnecessary for the living room 2. In other words, a situation occurs in which it is difficult to release a predetermined amount of hypochlorous acid into the living room 2.

The second control mode is therefore executed in periods when the humidification demand for the living room 2 is low (e.g., mid-season and summer in Japan), i.e., in situations where it is difficult to release a predetermined amount of hypochlorous acid into the living room 2 in the first control mode. In the second control mode, the rotation operation of the micronization unit 41 is executed at a rotation speed specified based on the hypochlorous acid demand, and hypochlorous acid is released into the living room 2 regardless of the humidification demand, so that the amount of hypochlorous acid released into the living room 2 can be increased compared to the first control mode.

As described above, the spatial purification device 40 performs humidification purification operation by combining the first control mode and the second control mode, which makes it possible to release a predetermined amount of hypochlorous acid into the living room 2 regardless of the season, thereby maintaining the cleanliness of the living room 2 throughout the year.

As described above, the spatial purification device 40 according to the first embodiment can provide the following effects.

(1) The space purification device 40 includes a micronization unit 41 that adds hypochlorous acid to the air introduced from the living room 2 by pumping the stored hypochlorous acid water and centrifugal crushing, and a control unit 60 that controls the rotation operation during centrifugal crushing in the micronization unit 41. The control unit 60 has a first control mode that controls the rotation speed of the micronization unit 41 based on the humidification request amount for the living room 2, and a second control mode that controls the rotation speed of the micronization unit 41 based on the hypochlorous acid request amount for the living room 2, and executes the first control mode when the operation mode information transmitted from the air conditioning device 13 that adjusts the temperature of the air introduced from the living room 2 to the micronization unit 41 indicates heating operation, and executes the second control mode when the operation mode information indicates cooling operation.

According to this configuration, when the air conditioner 13 is in heating operation, that is, when the relative humidity of the living room 2 is low and the amount of humidification can be increased (for example, in the winter in Japan), the first control mode is executed, while when the air conditioner 13 is in cooling operation, that is, when the humidification demand for the living room 2 is low (for example, in the summer in Japan), the second control mode is executed. As a result, in the winter in Japan, the finer unit 41 performs a rotation operation based on the humidification demand, so that the amount of hypochlorous acid released into the living room 2 can be easily adjusted according to the humidification demand. On the other hand, in the summer in Japan, the finer unit 41 performs a rotation operation based on the hypochlorous acid demand, so that the amount of hypochlorous acid released into the living room 2 can be easily adjusted regardless of the humidification demand. In other words, in the space purification device 40, the first control mode and the second control mode are combined to perform the humidification purification operation, making it easier to adjust the amount of hypochlorous acid released into the air throughout the year.

(2) In the space purification device 40, the control unit 60 executes the second control mode when the operation mode information of the air conditioner 13 indicates heating operation and the temperature difference between the set temperature of the room 2 (room set temperature) and the outside air temperature outside the room 2 is equal to or lower than a reference temperature (e.g., 6°C). As a result, in a situation where the heating operation of the air conditioner 13 is substantially stopped, the micronization unit 41 executes a rotation operation based on the hypochlorous acid demand amount, so that the amount of hypochlorous acid released into the room 2 can be adjusted without creating a situation where it is difficult to release a predetermined amount of hypochlorous acid into the room 2.

(3) In the spatial purification device 40, the control unit 60 executes the second control mode when the operation mode information indicates that the air conditioning device 13 is stopped. As a result, during periods when air conditioning of the living room 2 is not required (for example, intermediate periods that are the transitional period between summer and winter in Japan), the micronization unit 41 executes a rotation operation based on the hypochlorous acid demand amount, so that the amount of hypochlorous acid released into the living room 2 can be adjusted without creating a situation in which it is difficult to release a predetermined amount of hypochlorous acid into the living room 2.

The present invention has been described above based on the embodiments, but the present invention is in no way limited to the above embodiments, and it can be easily imagined that various improvements and modifications are possible within the scope of the invention without departing from its spirit.

In the spatial purification device 40 according to this embodiment, the control unit 60 may control the rotation operation to switch to the first control mode if the humidity in the living room 2 becomes equal to or higher than the reference humidity (e.g., relative humidity 80%) while the rotation operation is being performed in the second control mode. This allows the amount of humidification associated with the release of hypochlorous acid into the living room 2 to be adjusted so that the living room 2 is not over-humidified.

In addition, in the spatial purification device 40 according to this embodiment, the micronization unit 41 is configured to control the water stop state and the drain state of the hypochlorous acid water stored in the mixing tank 42 by the rotational operation of the lift pipe 43a, but this is not limited to this. For example, the micronization unit 41 may be configured to control the water stop state and the drain state of the hypochlorous acid water stored in the mixing tank 42 using a general drainage mechanism (e.g., a drainage valve). However, in this case, the lower limit rotation speed in the first control mode must be interpreted as 0 rpm. With such a configuration, the above-mentioned effects can also be enjoyed.

The spatial purification device of the present invention can easily adjust the amount of hypochlorous acid released into the air when micronizing hypochlorous acid water and releasing the hypochlorous acid into the air, and is useful as a device for sterilizing or deodorizing the air in a target space.
