DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Hereinafter, the embodiments of the present disclosure will be described with reference to the drawings. The present disclosure is not limited to the following embodiments, and can be modified in various ways without departing from the spirit of the present disclosure. The present disclosure includes all combinations of the configurations shown in the following embodiments that can be combined. In particular, the combination of components is not limited to the combinations in each embodiment, and the components described in one embodiment can be applied to another embodiment. The configurations shown in the drawings are examples of the configurations of the present disclosure, and the present disclosure is not limited by the configurations shown in the drawings. In the following description, terms indicating directions (e.g., "upper", "lower", "right", "left", "front", "rear", etc.) are used as appropriate to facilitate understanding, but these are for explanation and do not limit the present disclosure. In each drawing, the same reference numerals are assigned to the same or equivalent parts, and this is common throughout the entire specification. In each drawing, the relative dimensional relationship or shape of each component may differ from the actual one.

[0014] Embodiment 1 Fig. 1 is an external perspective view of a target space S in which a sterilization / virus inactivation apparatus 1 according to embodiment 1 is installed. As shown in Fig. 1, the sterilization / virus inactivation apparatus 1 according to embodiment 1 is used in a target space S such as an office or the like.

[0015] First, the infection route of bacteria or viruses will be described. In the present disclosure, the target of sterilization or inactivation is a microorganism including a pathogenic microorganism, such as a bacteria or a virus. Infection routes include droplet infection, contact infection, and airborne infection. Droplet infection is infection caused by bacteria or viruses contained in "droplets" such as saliva scattered by coughing or sneezing coming into contact with the mucous membrane of the mouth or nose. Contact infection is infection caused by an infected person covering a sneeze or cough with their hand, and then another person 50 touches something around them that has been touched by that hand, and the infection spreads through the mucous membrane of the mouth or nose.

[0016] Airborne infection is infection through microparticles of bacteria or viruses that are smaller than droplets in the air, specifically, microparticles generated by coughing or sneezing, or particles generated by evaporation of droplet water. In other words, airborne infection is infection by bacteria or viruses that are made up of microparticles smaller than droplets. Microparticles of bacteria or viruses that are smaller than droplets include particles that are originally generated as small particles when coughing or sneezing, and particles that are generated by evaporation of water from droplets dispersed in the air.

[0017] In addition, because droplets are heavy, they quickly fall to the floor after coughing or sneezing. In addition, wearing a mask can prevent droplets from scattering. Bacteria or viruses present in the air are easily inactivated due to falling to the floor, adhering to walls, or drying out (Shinohara Naohide, Introduction of research cases related to indoor environments useful for novel coronavirus infection control (First Edition), Indoor Environment Society (2020)).

[0018] On the other hand, it has been confirmed that bacteria or viruses that are attached to indoor fixtures 91 through contact with the person 50 or droplets emitted from the person 50 fall and remain active for at least twice as long as bacteria or viruses present in the air. For these reasons, in order to reduce the risk of infection from bacteria or viruses, it is considered important to have a technology to prevent contact infection, specifically, a technology to disinfect bacteria or inactivate viruses attached to indoor fixtures 91, and these technologies are currently in demand. Fixtures 91 refer to tools and fixtures present in a specified space, and in indoor spaces such as ordinary homes, they refer to tables and counters, and in indoor spaces such as offices, they refer to tools used in daily life that are present in the space, including workbenches, desks, and shelves.

[0019] The sterilization / virus inactivation device 1 is installed at a high position such as the ceiling in a target space S for sterilization of bacteria or inactivation of viruses, and is a device that transports a specific substance for sterilization or inactivation treatment to the target space S. The target space S is a closed space where people 50 enter and exit, such as a space separated by a partition and with a door 90 for entering and exiting the space, such as an office. Fixtures 91 such as work desks or chairs are arranged in the target space S.

[0020] [Structure of sterilization and virus inactivation device] Fig. 2 is a perspective view of the sterilization / virus inactivation apparatus 1 pertaining to embodiment 1. Fig. 3 is a cross-sectional view of the sterilization / virus inactivation apparatus 1 pertaining to embodiment 1. In the following, directions such as up and down are based on the installation posture of the sterilization / virus inactivation apparatus 1 shown in Figs. 2 and 3.

[0021] As shown in Fig. 2 and Fig. 3, the housing 1a of the sterilization / virus inactivation apparatus 1 has a first case 2, a second case 3 detachably attached above the first case 2, and a grill body 4 detachably attached below the first case 2. A base 7 connected to a fixing jig attached to a high place such as a ceiling is attached to the upper end of the housing 1a. The sterilization / virus inactivation apparatus 1 is configured so that commercial power is supplied to the power supply device through the base 7 by connecting the base 7 to the fixing jig. A display unit 36 ​​that displays the operating state of the sterilization / virus inactivation apparatus 1 is attached to the outer wall of the housing 1a, which is the outer wall of the grill body 4 in Fig. 2.

[0022] The sterilization / virus inactivation apparatus 1 further has a presence / absence information input unit 85 communicably connected to the control device 40 in the first case 2. The presence / absence information input unit 85 is disposed separately from the housing 1a.

[0023] The first case 2 has a cylindrical tubular portion 21 and an annular upper surface portion 23 that covers the upper end opening of the tubular portion 21. A plurality of air intake ports 23a that draw in air from the outside are formed in the upper surface portion 23 at intervals in the circumferential direction. A filter (not shown) is detachably provided on the inner surface side of the air intake port 23a. A tubular air passage forming member 27 that communicates with the air intake port 23a is fixed in the first case 2, and the inside of the air passage forming member 27 forms the ventilation path 24. The upstream side of the ventilation path 24 communicates with the air intake port 23a. The downstream side of the ventilation path 24 is located in the grill body 4, and the air flow that flows out from the outlet of the ventilation path 24 flows into the grill body 4 and is blown out to the outside. The external shape of the housing 1a is not limited to the above shape, and the external shape is arbitrary, such as the tubular portion 21 of the first case 2 being configured as a tube with a rectangular cross section.

[0024] A connector 25 for connecting the first case 2 to the second case 3 is provided on an upper surface 23 of the first case 2. The connector 25 constitutes a part of the first case 2. The first case 2 is detachably attached to the second case 3 by a hook portion 25a provided on the connector 25 being locked with a locking portion 26 provided on the lower end portion of the second case 3.

[0025] The grill body 4 is disposed so as to cover the outlet opening of the ventilation passage 24 of the first case 2, and is located on the central axis of the ventilation passage 24. The grill body 4 is supported by the inner wall of the first case 2. The grill body 4 has a plurality of linear fins 6 on its lower part.

[0026] Inside the housing 1a, a substance generating section 32, a transporting section 33, a trajectory detecting section 31, a substance measuring section 34, and a main board 35 are arranged.

[0027] Each component part of the sterilization / virus inactivation device 1 will be described below.

[0028] [Presence information input section 85] The presence / absence information input unit 85 is a part that transmits information regarding the presence or absence of the person 50 in the target space S, that is, information regarding presence or absence, to the sterilization / virus inactivation apparatus 1. The information regarding the presence or absence of the person 50 is the time when the person 50 is absent in the target space S, and is the time when the person 50 is scheduled to be absent. The information regarding the presence or absence of the person 50 may include presence information regarding the presence of the person 50 in the target space S, and absence information regarding the absence of the person 50 in the target space S.

[0029] The presence / absence information input unit 85 is configured with, for example, a timer controller board. An absence time, which is a time when the person 50 is scheduled to be absent from the target space S, is input to the presence / absence information input unit 85. The time when the person 50 entered the target space S, or the entry time, which is the scheduled time of entry, may be input to the presence / absence information input unit 85. Furthermore, the presence / absence information input unit 85 may be inputted with a time when the person 50 left the target space S, or the exit time, which is the scheduled time of exit. Furthermore, the presence / absence information input unit 85 may be inputted with an entry time and a stay time.

[0030] The presence / absence information input unit 85 can communicate with the control device 40. Information on the presence or absence of the person 50 inputted by the presence / absence information input unit 85 is transmitted to the control device 40 and acquired by the presence / absence information acquisition unit 84 of the control device 40. Wireless communication such as wireless LAN, Bluetooth (registered trademark), or ZigBee (registered trademark) is used for communication between the presence / absence information input unit 85 and the control device 40. The presence / absence information input unit 85 may be in the shape of a remote control that can be carried around in the target space S, or may be mounted in the target space S. Furthermore, the presence / absence information input unit 85 may be equipped in the sterilization / virus inactivation device 1. Details of the configurations and operations of the presence / absence information input unit 85 and the presence / absence information acquisition unit 84 will be described again below.

[0031] [Material Generation Section 32] The substance generating unit 32 generates a specific substance, such as ions, ozone gas, chlorine dioxide, or hypochlorous acid water, that can sterilize or inactivate microorganisms, including pathogenic microorganisms, carried by the person 50. The substance generating unit 32 is attached to the inner wall of the air passage forming member 27. The substance generating unit 32 includes, for example, a discharge mechanism that generates ions. The discharge mechanism is disposed so as to face the air passage 24 in the first case 2. The discharge mechanism has a unitized configuration in which a discharge unit and an electrode cover that covers the discharge unit are disposed in the case. Furthermore, the discharge mechanism incorporates a control circuit board equipped with a high-voltage generating circuit and the like. The control circuit board is provided with a connector that supplies power from the outside.

[0032] The discharge unit has a discharge electrode and a ground electrode. The discharge electrode is composed of a wire electrode, and the installation electrode is composed of a plate electrode. The discharge unit has a configuration in which a plurality of wire electrodes and a plurality of plate electrodes are arranged alternately. A high voltage is supplied to the discharge unit from a high voltage generating circuit. The high voltage generating circuit has a power receiving unit that receives power from a commercial power source, and converts the power received by the power receiving unit through a connector and an electric wire into a high voltage and supplies it to the discharge unit. The discharge unit applies the high voltage supplied from the high voltage generating circuit between the discharge electrode and the ground electrode to cause a discharge and generate ions in the air. Here, the discharge unit is described as having a discharge electrode composed of a wire electrode and an installation electrode composed of a plate electrode, but this is merely an example, and both the discharge electrode and the ground electrode may be formed of any of a wire electrode, a needle electrode, a plate electrode, and a brush electrode.

[0033] [Transportation Department 33] The transport section 33 generates an air flow. The transport section 33 includes a blower 37 that generates the air flow. The transport section 33 may include a drive device 39 that drives the first case 2.

[0034] (Blower 37) The blower 37 includes a blower fan and a fan motor for driving the fan. The fan is disposed on the outlet side of the ventilation passage 24 and is supported by the inner wall of the first case 2 so as to be located on the central axis of the ventilation passage 24. An axial-flow propeller fan is used for the fan in order to generate a large volume of airflow. An AC capacitor motor is used for the fan motor. When the fan is driven in the blower 37, the air around the first case 2 is sucked into the first case 2 in the radial direction from the intake port 23a and flows into the inlet of the ventilation passage 24. The air flow that flows into the inlet of the ventilation passage 24 changes direction from a radial flow to an axial flow. Then, the air that flows in the axial direction through the ventilation passage 24 is blown out of the housing 1a from the outlet of the ventilation passage 24.

[0035] The blower 37 is disposed downstream of the substance generating unit 32 in the ventilation passage 24. As a result, the specific substance generated in the substance generating unit 32 is mixed with the air in the fan of the blower 37, and the air is blown out of the housing 1a with the ion concentration in the air being homogenized.

[0036] (Driver 39) The driving device 39 drives the first case 2 to change the orientation of the grill 4a, thereby controlling the direction of the airflow blown out from the grill 4a. When the driving device 39 drives the first case 2, the bellows-shaped second case 3 is deformed, changing the airflow direction. The driving device 39 is equipped with a motor (not shown) that can drive two orthogonal axes. The motor is a general servo motor or a stepping motor. These motors control the angle of the shaft supporting the first case 2, and can stop the shaft supporting the first case 2 at a specific position.

[0037] [Materials Measurement Division 34] The substance measuring section 34 includes an ion sensor that measures discharge products in the air. The ion sensor is disposed downstream of the substance generating section 32 in the air flow direction in the ventilation passage 24. A coaxial double cylinder type sensor that measures positive ions or negative ions in the air is used as the ion sensor. This allows the ion sensor to simultaneously measure positive ions and negative ions, and to measure a concentration of 100,000 to 3,000,000 (ions / cm). 3 ) with high accuracy. The measurement results of the substance measuring unit 34 are output to the control device 40. When the specific substance generated in the substance generating unit 32 is ozone, the substance measuring unit 34 is configured with an ozone gas sensor that measures ozone in the air.

[0038] FIG. 4 is a graph showing the relationship between ion concentration and sterilization / inactivation effect. In FIG. 4, the horizontal axis represents ion concentration (ions / cm 3 ) and the vertical axis shows the survival rate of microorganisms (-). 3 ) or more, the sterilization and inactivation effects appear, and as the ion concentration becomes higher, the sterilization and inactivation effects improve further. For this reason, the substance generating unit 32 is 3 ) or more ions are generated.

[0039] [Display section 36] The display unit 36 ​​is attached to the outer wall surface of the grill body 4 as an electronic component for transmitting information. The display unit 36 ​​is composed of light-emitting diodes (LEDs) that notify various types of information. The display unit 36 ​​indicates the operating state of the sterilization / virus inactivation device 1 by the lighting state of the light-emitting diodes. The display unit 36 ​​can change the lighting state by appropriately combining the light-emitting color of the light-emitting diodes and the lighting format, such as blinking or lighting. The display unit 36 ​​can indicate that the sterilization / virus inactivation process is in progress or notify of an abnormality by changing the lighting state of the light-emitting diodes.

[0040] [Main board 35] A control device 40 (see FIG. 5) that controls the entire sterilization / virus inactivation device 1, a power supply device that supplies power to each component, and the like are mounted on the main board 35. The main board 35 is fixed to the side wall of the air-path forming member 27 of the first case 2. The control device 40 is composed of a microprocessor unit and the like, and includes a CPU, RAM, ROM, and the like, and a control program and the like are stored in the ROM.

[0041] The control device 40 calculates the processing conditions in the processing condition calculation unit 86 based on the information on the presence or absence of the person 50 inputted in the presence or absence information input unit 85. The control device 40 controls the substance generation unit 32 and the transport unit 33 by the processing execution unit 88 based on the processing conditions calculated in the processing condition calculation unit 86. The control device 40 can also control the display unit 36 ​​based on the measurement result of the substance measurement unit 34. Specifically, when the control device 40 detects that the specific substance is equal to or lower than a preset concentration based on the measurement result of the substance measurement unit 34, it stops the operation of the substance measurement unit 34 and lights up the display unit 36. When an abnormality occurs in the substance measurement unit 34, the control device 40 controls the display unit 36 ​​to be in a lit state indicating the abnormality of the substance measurement unit 34. This allows the sterilization / virus inactivation device 1 to notify the occurrence of an abnormality.

[0042] Fig. 5 is a functional block diagram of the sterilization / virus inactivation apparatus 1 according to embodiment 1. As shown in Fig. 5, the control device 40 has a presence / absence information acquisition unit 84, a processing condition calculation unit 86, a processing execution unit 88, a substance generation unit 32, a transport unit 33, and a display unit 36 ​​electrically connected thereto by lead wires. The control device 40 also has a function of performing wireless communication via wireless LAN, Bluetooth (registered trademark), ZigBee (registered trademark), or the like, and performs wireless communication with a presence / absence information input unit 85.

[0043] [Presence / absence information input section 85 and presence / absence information acquisition section 84] The sterilization / virus inactivation apparatus 1 communicates wirelessly with the presence / absence information input unit 85, and acquires data on the presence / absence of person 50 in the presence / absence information acquisition unit 84. Specific examples of information input to the presence / absence information input unit 85 include the reservation and usage status of a conference room, whether the lights are on or off, or the locking status of door 90.

[0044] The information entered into the presence / absence information input unit 85 can be obtained by linking with the presence management that is manually entered. In the presence management, a list of presence / absence is created and the presence / absence of each user in the target space, i.e., the room, is entered. By linking with the presence management, it is possible to perform individual management for each room. It is also easy to deal with spaces that are created temporarily.

[0045] The information input to the presence / absence information input unit 85 can also be obtained by linking with a reservation system that reserves spaces such as offices. The reservation system is, for example, a system for reserving rooms or seats via an app or the like, and the items input include, for example, date, time period, whether or not the reservation is repeated, the number of users, and the purpose of use. When linking with a reservation system, the processing conditions and processing time may be output and displayed on a schedule. This notifies the user that processing is in progress, ensuring safety, and allows the user to predict the completion time, making it easier to make plans.

[0046] The information input to the presence / absence information input unit 85 can also be obtained by linking with a building management system for an office or the like. The building management system is, for example, a system that monitors and controls various facilities such as power, air conditioning, lighting, disaster prevention, and crime prevention in a building such as an office. The input information includes image information from a surveillance camera or a 360° camera, or information on the entry and exit of a person 50 from an entry and exit management system. The image information can be used to check the presence or absence of a person 50 in the target space S. Furthermore, the entry and exit information can be used when checking the presence or absence of a person 50 in the target space S and when performing processing after closing.

[0047] The information input to the presence / absence information input unit 85 can also be input based on information acquired by an infrared sensor. The infrared sensor has a transmitting unit that transmits infrared rays and a receiving unit that receives infrared rays, and is installed, for example, at a door 90 provided in the target space S. When the person 50 does not pass between the transmitting unit and the receiving unit, the amount of infrared rays received by the receiving unit does not change and is approximately constant, but when the person 50 passes, the amount of infrared rays received decreases. When the amount of infrared rays received by the receiving unit falls below a specified value, the movement of the person 50 is detected. A method of detecting the entry and exit of the person 50 using an infrared sensor is simpler and can be configured at a lower cost as a device configuration than a method of detecting entry and exit using image data.

[0048] The presence / absence information acquisition unit 84 determines the absence time of the person 50 based on the data regarding the presence / absence of the person 50 inputted to the presence / absence information input unit 85. The information on the absence time of the person 50 determined by the presence / absence information acquisition unit 84 is notified to the processing condition calculation unit 86.

[0049] The absence time of the person 50 is the time from when all the people 50 have left the target space S until the next person 50 enters. The absence time is determined, for example, based on the usage time input to the presence / absence information input unit 85. The absence time may be determined by patterning the absence times previously determined by the presence / absence information acquisition unit 84 and based on the information on the patterned absence times.

[0050] The presence / absence information acquisition unit 84 determines information regarding absence time depending on the type of information input by the presence / absence information input unit 85 and acquired by the presence / absence information acquisition unit 84. That is, when the information input by and acquired from the presence / absence information input unit 85 is information regarding the reservation of a conference room, the presence / absence information acquisition unit 84 determines the absence time from the reservation time. When the information input by and acquired from the presence / absence information input unit 85 is information regarding the usage status of the conference room, the presence / absence information acquisition unit 84 determines presence or absence from the reservation status.

[0051] Furthermore, when the information input and acquired from the presence / absence information input unit 85 is information regarding the turning on and off of the lighting devices in the target space S, the presence / absence information acquisition unit 84 determines the presence or absence of the person 50 in the target space S from the turning on and off information. The presence / absence information acquisition unit 84 can also be configured to estimate the absence time of the person 50 in the target space S from the turning on and off pattern based on the information regarding the turning on and off of the lighting devices in the target space S input and acquired from the presence / absence information input unit 85.

[0052] In addition, when the information acquired from the presence / absence information input unit 85 is the locking status of the door 90, the presence / absence information acquisition unit 84 can estimate the time from the opening / closing action at the time of entry to the opening / closing action at the time of exit.

[0053] [Processing condition calculation unit 86] The processing condition calculation unit 86 calculates absence processing conditions based on the absence time determined by the presence / absence information acquisition unit 84. The processing condition calculation unit 86 also calculates presence processing conditions based on the presence information determined by the presence / absence information acquisition unit 84. The sterilization / virus inactivation device 1 generates a specific substance in the target space S when there is no person 50 in the target space S, and the absence of people 50 in the target space S is a prerequisite for the sterilization / virus inactivation processing.

[0054] The sterilization and virus inactivation treatment includes a treatment using ozone and a treatment using negative ions. In the treatment using ozone, when the ozone concentration is increased, the sterilization power, that is, the treatment strength, is improved, and the effect of the treatment is also improved, while the influence on the members or substances present in the target space S is also increased. In the treatment using negative ions, the treatment strength is not as high as that of the ozone treatment, but the influence on the members present in the target space S is reduced. The treatment conditions include the treatment method, including whether the treatment is ozone treatment or negative ion treatment and the ozone concentration, and the treatment time, which is the time during which the ozone treatment and the negative ion treatment are performed. Therefore, the treatment condition calculation unit 86 selects treatment conditions that can be completed within the absence time based on the absence time of the person 50, that is, the time when the absence of the person 50 is scheduled.

[0055] For example, if the presence / absence information acquisition unit 84 acquires information regarding reservations for a conference room, such as a first reservation from 10:30 to 11:30 and a second reservation from 13:00 to 15:00, there will be a two-hour absence between the first and second reservations. In this case, the information on the processing time, which is the time that can be spent on processing, is less than two hours based on the absence time, so the processing condition calculation unit 86 selects absence processing conditions that can be completed in less than two hours.

[0056] [Processing execution unit 88] The processing execution unit 88 controls the operation of the substance generating unit 32, the transport unit 33, and the display unit 36 ​​based on the absent processing conditions selected by the processing condition calculation unit 86. Specifically, when the absent processing conditions are selected, the processing execution unit 88 instructs the substance generating unit 32 to generate a specific substance. Also, when the absent processing conditions are selected, the processing execution unit 88 instructs the transport unit 33 to drive the blower device 37. Also, when the absent processing conditions are selected, the processing execution unit 88 instructs the display unit 36 ​​to display that processing is in progress. Note that, when the present processing conditions are selected by the processing condition calculation unit 86, the processing execution unit 88 performs control to suppress the execution of the sterilization / virus inactivation processing. Specifically, when the present processing conditions are selected, control is performed so as not to generate a specific substance.

[0057] Fig. 6 is a table showing the absent processing conditions of the sterilization / virus inactivation apparatus 1 according to embodiment 1. As shown in Fig. 6, the processing condition calculation unit 86 selects the absent processing conditions from processing A, processing B, and processing C. The absent processing conditions are selected taking into consideration the absent time of person 50 as well as the required processing strength and the effect on components.

[0058] Treatment A is an ultra-fast treatment, and is a treatment condition selected when treatment is required in a relatively short time or when high sterilization power is required. Treatment A is an ozone treatment, and since it has an effect on the members present in the target space S, people 50 cannot enter or exit during treatment. In treatment A, specifically, ozone treatment with an ozone concentration of 0.5 ppm is performed for 3 minutes, and then ozone removal is performed for 12 minutes to remove ozone from the target space S. The treatment time by treatment A is 15 minutes in total. For ozone removal, for example, an activated carbon adsorption decomposition method in which ozone is adsorbed on activated carbon, a contact decomposition method in which ozone is contacted with silica or alumina, or a wet method in which ozone is dissolved in water can be adopted. In the wet method, an alkaline cleaning method using a high-concentration alkaline aqueous solution allows rapid ozone decomposition.

[0059] Process B is a normal process, and is a process condition selected when it is not known when the person 50 will enter, when there is a relatively long time before the next person 50 enters, or when there is a high possibility that the person 50 will enter and it is necessary to immediately interrupt the process. Process B is a process using negative ions, and has almost no effect on the members present in the target space S, and the person 50 can enter and exit during the process. In process B, specifically, negative ion processing with an ozone concentration of 0.05 ppm or less is performed for one hour, and it is not necessary to provide a time period for removing ozone. Therefore, the process time for process B is one hour in total, and the process is stopped when the person 50 enters the room.

[0060] Treatment C is a high-speed treatment, and the treatment conditions are medium in terms of the impact on the components present in the target space S and the time required for treatment. Specifically, treatment C is performed for 25 minutes with an ozone concentration of 0.1 ppm or less and negative ions, and is stopped 5 minutes before the entry of person 50. Therefore, the total treatment time for treatment C is 30 minutes.

[0061] For example, as in the above example, if a first reservation is made from 10:30 to 11:30 and a second reservation is made from 13:00 to 15:00, the processing time is less than two hours and any of conditions A to C can be selected. In this case, the processing condition can be selected taking into consideration the required processing intensity and the possibility of person 50 entering the room, etc.

[0062] For example, 12:00 between the first and second reservations is generally lunchtime, and it is considered that no person 50 will enter or leave. In this case, by selecting process A, the process can be completed before the afternoon reservation by ultra-high speed processing, and the process can be reliably completed even if person 50 enters the room early.

[0063] Also, for example, since the first and second reservations were both made during the day, it is conceivable that person 50 may suddenly enter the room even if no reservation has been made. In this case, by selecting process B, the process is immediately interrupted even if person 50 enters the room, and the room can be made available for entry.

[0064] Also, for example, it is conceivable that both the first and second reservations are internal meetings, and it would be easy to publicize that the target space S is undergoing processing. In this case, by selecting processing C, it is possible to achieve a state in which the processing intensity is relatively high and entry is possible in a relatively short time after processing stops.

[0065] In this way, by selecting absence processing conditions, it is possible to limit inconvenience to the user while still obtaining the benefits of the processing.

[0066] FIG. 7 is a control flowchart of the sterilization / virus inactivation apparatus 1 according to the first embodiment. As shown in FIG. 7, the sterilization / virus inactivation apparatus 1 performs sterilization / virus inactivation processing by the control device 40. When the processing starts, the control device 40 judges in step S01 whether a person 50 is absent from the target space S, and if it judges that the person 50 is present and not absent (NO in step S01), it repeats the processing. In this case, the control device 40 performs control to suppress the execution of the sterilization / virus inactivation processing by the processing execution unit 88 based on the presence processing condition selected by the processing condition calculation unit 86. Therefore, when a specific substance is generated by the substance generation unit 32, the processing execution unit 88 instructs the stop of generation of the specific substance.

[0067] On the other hand, when the control device 40 determines in step S01 that the person 50 is absent from the target space S (YES in step S01), it proceeds to step S02 and acquires processing time information. The processing time information is the time that can be spent on processing. The processing time information is the time calculated based on information regarding the absence time of the person 50 in the target space S acquired by the presence / absence information acquisition unit 84. The processing of step S02 is an example of a presence / absence information acquisition process.

[0068] The control device 40 then proceeds to step S03, where it selects processing conditions. The selection of processing conditions is performed by the processing condition calculation unit 86. In selecting the processing conditions, the processing condition calculation unit 86 first selects one of the processes A to C in light of processing time information based on the absence time acquired by the presence / absence information acquisition unit 84. The process of step S03 is an example of a processing condition calculation step.

[0069] The control device 40 then proceeds to step S04 and step S05, where the specific substance is generated in step S04 and transported in step S05. The generation and transport of the specific substance are controlled by the process execution unit 88. Specifically, the process execution unit 88 instructs the substance generation unit 32 to generate the specific substance and instructs the transport unit 33 to drive the blower 37.

[0070] For example, when process A is selected as the process condition, the process execution unit 88 instructs the substance generation unit 32 to generate ozone as the specific substance, to set the ozone concentration to 0.5 ppm, and to maintain the concentration for 3 minutes. The process execution unit 88 also instructs the transport unit 33 to start driving the blower 37.

[0071] The control device 40 then proceeds to step S06, where it determines whether the process has been completed, and if the process has not been completed, it repeats the process (NO in step S06), and if the process has been completed, it ends the process (YES in step S06). For example, when process A is selected as the process condition, the process execution unit 88 instructs the transport unit 33 to continue driving for 13 minutes after the generation of ozone has ended, and the process ends after the 13 minutes have passed. The processes in steps S04, S05, and S06 are an example of a process execution step.

[0072] The above processes are performed by the control device 40, whereby the sterilization process and virus inactivation process by the sterilization / virus inactivation device 1 is completed.

[0073] When the sterilization process or the virus inactivation process is being performed, the control device 40 instructs the display unit 36 ​​to display that the process is in progress. The display unit 36 ​​may also be configured to display the time remaining until the process is completed. This allows the user to know the time until he or she can enter the target space S.

[0074] <Variation 1> Fig. 8 is a schematic diagram showing a usage form of the sterilization / virus inactivation apparatus 1 according to Modification 1 of Embodiment 1. As shown in Fig. 8, the sterilization / virus inactivation apparatus 1 can be used for sterilization or virus inactivation processing in spaces such as restaurants or classrooms. In this case, for example, by assigning a sterilization / virus inactivation apparatus 1 to each table and arranging them so that airflow is transported toward the space including each table, sterilization and virus inactivation processing can be effectively performed for the target space S.

[0075] According to the sterilization / virus inactivation device 1 of the first embodiment described above, the presence / absence information acquisition unit 84 acquires presence / absence information, and the absence processing conditions are calculated according to the absence time. This allows the sterilization or virus inactivation processing to be completed within the absence time, so that the sterilization or inactivation processing can be performed in an efficient manner that can be completed within the absence time with the person 50 reliably absent. Furthermore, in the first embodiment, ions or ozone are transported by non-directional wind, so that a partitioned space, that is, the inside of a room, can be treated as a whole.

[0076] Furthermore, when the present processing condition is calculated by the processing condition calculation unit 86, the execution of the sterilization or virus inactivation processing is suppressed. Therefore, when the person 50 is present in the target space S, the sterilization or virus inactivation processing using the specific substance is not performed, and it is possible to suppress the influence of the specific substance on the target space in which the person 50 is present.

[0077] In addition, since the absence processing conditions are calculated and selected based on the absence time acquired by the presence / absence information acquisition unit 84, processing that takes into consideration safety and the impact on components within the space can be carried out and completed within the absence time.

[0078] In addition, after obtaining information on the absence of person 50, processing is carried out under selected conditions, and specific substances are generated according to the absence processing conditions based on the presence / absence information, so processing can be carried out while taking into consideration safety and the impact on components.

[0079] Furthermore, the presence / absence information acquisition unit 84 determines the presence / absence based on obtainable information, such as the reservation of the conference room, the usage status of the conference room, the on / off status of the lights in the target space S, or the lock status of the door 90 that opens and closes the target space S. This makes it easy to acquire information and improves the accuracy of the information.

[0080] In addition, when the presence / absence information acquisition unit 84 determines that there is no person 50 in the target space S, the substance generation unit 32 and the transportation unit 33 perform sterilization or virus inactivation processing in the target space S depending on the time of absence, thereby enabling efficient processing.

[0081] Furthermore, in the sterilization / virus inactivation method according to embodiment 1, information regarding presence and absence is acquired in a presence / absence information acquisition step, and absence treatment conditions are calculated in a treatment condition calculation step, and the sterilization treatment or virus inactivation treatment is completed when person 50 is absent. Therefore, sterilization or virus inactivation treatment can be performed efficiently when person 50 is absent.

[0082] Embodiment 2 FIG. 9 is a perspective view of the sterilization / virus inactivation apparatus 1 according to the second embodiment. FIG. 10 is a cross-sectional view of the sterilization / virus inactivation apparatus 1 according to the second embodiment. FIG. 11 is a side view showing the grill body 4 of the sterilization / virus inactivation apparatus 1 according to the second embodiment. FIG. 12 is a schematic diagram showing a mode of use of the sterilization / virus inactivation apparatus 1 according to the second embodiment. The second embodiment differs from the first embodiment in that the transport section 33 imparts linearity and directionality to the airflow. The following description will focus on configurations and processes in the second embodiment that are different from the first embodiment, and configurations and processes not described in the second embodiment are similar to those in the first embodiment.

[0083] As shown in Figs. 9 to 12, the sterilization / virus inactivation apparatus 1 is configured such that the transport section 33 has a grill 4a provided on the grill body 4 and generates an airflow that is highly linear and directional.

[0084] The grill 4a, which gives straightness and directionality to the airflow, is provided at the lower part of the grill body 4, at the air outlet 5 of the grill body 4. The grill 4a constitutes a part of the transport section 33. The grill 4a has a plurality of spiral fins 6. The grill 4a has a structure in which the inner end 6a of the plurality of fins 6, which is close to the center O of the spiral, protrudes in the airflow direction from the outer end 6b of the fins 6 that is continuous with the air outlet 5. In other words, the inner end 6a of the fins 6 of the grill 4a protrudes in the airflow direction compared to the outer end 6b of the fins 6. The inner end 6a is the inner end side close to the center O of the spiral, and includes the vicinity of the inner end. The outer end 6b is the part on the outer end side that is continuous with the air outlet 5.

[0085] With this configuration, the grill 4a can collect and converge the airflow that flows out from the outlet of the ventilation passage 24 and into the grill body 4, improving the wind speed at the center of the airflow direction. The grill 4a can also extend the reach of the spiral airflow blown out from the air outlet 5. As described above, the grill 4a can impart straightness and directionality to the airflow generated by the air blower 37, enabling effective sterilization and virus inactivation processing.

[0086] The transport unit 33 may be configured such that the first case 2 is driven by a drive device 39 in order to transport the airflow that has been given linearity and directionality. In this case, the second case 3 is configured, for example, of a flexible bellows-like member. The drive device 39 can orient the grill 4a provided in the air outlet 5 in a desired direction, so that the direction of the airflow can be changed, for example, from a vertical downward direction to an oblique direction.

[0087] With the above configuration, the transport section 33 can generate an airflow using the air blower 37 and make the airflow more linear and directional using the grill 4a, thereby effectively carrying out sterilization and virus inactivation treatments. In the second embodiment, ions and ozone are transported using directional wind, so that only a part of a space or a specific part such as a place that a person has come into contact with can be treated.

[0088] The transport unit 33 may be configured to transport the airflow toward the moving trajectory portion P, which is the portion with which the object comes into contact, in cooperation with the trajectory detection unit 31. The moving trajectory portion P is detected, for example, by the trajectory detection unit 31 disposed in the center of the lower end of the grill body 4. The trajectory detection unit 31 detects the moving trajectory of the portion with which the moving object comes into contact, and the moving object to be subjected to trajectory detection may be any moving object, including a living moving object including a person 50, a pet such as a dog or a cat, as well as a moving device such as a mobile vacuum cleaner.

[0089] By the transport unit 33 working in conjunction with the trajectory detection unit 31, the air flow can be transported toward the movement trajectory portion P, which is the part where the object came into contact, thereby enabling effective sterilization and virus inactivation processing.

[0090] <Variation 1> Fig. 13 is a schematic diagram showing a usage form of the sterilization / virus inactivation apparatus 1 according to Modification 1 of Embodiment 2. Fig. 14 is a schematic diagram showing another usage form of the sterilization / virus inactivation apparatus 1 according to Modification 1 of Embodiment 2.

[0091] 13 and 14, the sterilization / virus inactivation apparatus 1 may be configured to be linked to reservation information for each seat 92. Specifically, reservation information for each seat 92 is input to the presence / absence information input unit 85, and after a person 50 uses the seat 92, sterilization / virus inactivation processing is performed on the space in which the used seat 92 is located. In this way, the sterilization / virus inactivation apparatus 1 can also be configured to perform sterilization / virus inactivation processing on a spot basis, and sterilize or inactivate viruses in the space around the seat.

[0092] The form of the reservation information for each seat 92 is not particularly limited, and may be, for example, input from a seat reservation system that reserves the seat 92 via an app or the like. The reservation information for each seat may be, for example, information input by a user in a seat occupancy list according to seat occupancy management.

[0093] Embodiment 3 Fig. 15 is a schematic cross-sectional view of an air conditioner 60 equipped with a sterilization / virus inactivation apparatus 1 according to embodiment 3. Fig. 16 is a bottom view of an air conditioner 60 equipped with a sterilization / virus inactivation apparatus 1 according to embodiment 3. Embodiment 3 relates to an air conditioner 60 equipped with a sterilization / virus inactivation apparatus 1. The following description will focus on configurations and processes in embodiment 3 that differ from embodiments 1 and 2, and configurations and processes not described in embodiment 3 are the same as embodiment 1 or 2.

[0094] As shown in Figs. 15 and 16, the air conditioner 60 is an indoor unit placed in a space to be air-conditioned, such as an office, and supplies temperature-controlled air to the space to be air-conditioned by utilizing a refrigeration cycle that circulates a refrigerant. The air conditioner 60 performs one or both of heating and cooling operations as normal operations. The air conditioner 60 conditions the space to be air-conditioned, and is equipped with a sterilization / virus inactivation device 1, and sterilizes bacteria or inactivates viruses in the space to be air-conditioned, which is a target space S. The sterilization / virus inactivation device 1 equipped in the air conditioner 60 is, for example, the sterilization / virus inactivation device 1 of embodiment 1 or 2.

[0095] The air conditioner housing 61 constituting the outer shell of the air conditioner 60 includes an air conditioner main body 62 that is embedded in the ceiling and has an opening on the bottom, and a decorative panel 63 that covers the opening of the air conditioner main body 62. The decorative panel 63 has a rectangular intake grill 64 in the center. Four air outlets 65 are formed around the intake grill 64 along the four sides of the intake grill 64. Each air outlet 65 is provided with an air deflector 66 that controls the direction of the airflow from the air outlet 65. The air conditioner 60 includes, as the air deflector 66, an up-down air deflector 66a that controls the wind direction in the up-down direction, and a left-right air deflector 66b that controls the wind direction in the left-right direction. In addition, a motor (not shown) that drives the up-down air deflector 66a and the left-right air deflector 66b is provided inside the air conditioner housing 61.

[0096] In the air conditioner housing 61, a centrifugal blower 67, a motor 68 for driving the centrifugal blower 67, and a heat exchanger 69 for exchanging heat between the refrigerant flowing inside and the air are arranged. The centrifugal blower 67 is arranged in the center of the air conditioner housing 61, and is connected to a shaft extending downward from the motor 68 fixed to the top plate of the air conditioner housing 61. The heat exchanger 69 is arranged around the centrifugal blower 67. In addition, in the air conditioner housing 61, a drain pan 70 for receiving condensation water generated in the heat exchanger 69 is arranged below the heat exchanger 69. Furthermore, an electric equipment box 71 is arranged in the air conditioner housing 61. The electric equipment box 71 houses a control board 71a for controlling the operation of the air conditioner 60. Note that, in FIG. 15, an example in which the air conditioner 60 is a ceiling-suspended indoor unit is shown, but this is not limited thereto, and the air conditioner 60 may be a wall-mounted indoor unit.

[0097] The air conditioner 60 is provided with a sterilization / virus inactivation device 1. Specifically, for example, the substance generating unit 32 constituting the sterilization / virus inactivation device 1 is disposed near the air outlet 65 of the decorative panel 63. The transport unit 33 is configured to include a centrifugal blower 67, an air deflector 66, and a motor (not shown) that drives the air deflector 66. The centrifugal blower 67 is also used as the air blower 37 of the transport unit 33. The air deflector 66 has the function of the grill 4a of the transport unit 33. The display unit 36 ​​is disposed on the outer surface of the decorative panel 63. The function of the control device 40 is mounted on a control board 71a in the electric equipment box 71. The decorative panel 63 is provided with a sensing unit 30 equipped with an infrared sensor. The infrared sensor mounted on the sensing unit 30 can acquire information to be input to the presence / absence information input unit 85.

[0098] Fig. 17 is a schematic diagram illustrating a sterilization / virus inactivation operation by an air conditioner 60 equipped with a sterilization / virus inactivation device 1 according to embodiment 3. As shown in Fig. 17, the air conditioner 60 is installed in a position where it can transport an air flow to the target space S.

[0099] In the air conditioner 60, when the centrifugal blower 67 is rotated by the motor 68, air is sucked into the air conditioner housing 61 through the intake grille 64, passes through the centrifugal blower 67 and the heat exchanger 69, and is blown out from the outlet 65. The airflow blown out from the outlet 65 is an airflow whose temperature has been adjusted by the heat exchanger 69, and contains the specific substance generated in the substance generating section 32. Such an airflow is blown out from the outlet 65 and transported to the target space S. Furthermore, when the blowing direction is controlled by the air deflector 66, the airflow with improved linearity and directionality can be transported in a desired direction of the target space S.

[0100] The air conditioner 60 according to embodiment 3 described above is equipped with the sterilization / virus inactivation apparatus 1 according to embodiment 1 or 2, and acquires information regarding the presence or absence of person 50 by the presence / absence information acquisition unit 84. The sterilization / virus inactivation apparatus 1 then calculates optimal processing conditions by the processing condition calculation unit 86 in accordance with the absence time of person 50, thereby enabling it to complete the sterilization or virus inactivation processing of the target space S to be air-conditioned within the absence time.

[0101] In addition, various embodiments and modifications of the present disclosure are possible without departing from the broad spirit and scope of the present disclosure. In addition, the above-mentioned embodiments are intended to explain the present disclosure and do not limit the scope of the present disclosure. In other words, the scope of the present disclosure is indicated by the claims, not the embodiments.
