Description

[Technical Field]

[0001] The present disclosure relates to an inhibitor dissipation device, an inhibitor dissipation system, and an inhibitor dissipation method. [Background technology]

[0002] Conventionally, it has been considered to make a target space less inviting for insects by diffusing an inhibitor that inhibits insect activity into the target space.

[0003] In the pest control material disclosed in Patent Document 1, the amount of the room temperature volatile pyrethroid compound held in the carrier is set based on the maximum daily volatilization amount of the pyrethroid compound and the planned usage period. In Patent Document 1, the maximum daily volatilization amount of the pyrethroid compound is set based on the volatilization temperature characteristics of the pyrethroid compound.

[0004] [Patent Document 1] International Publication No. 2017 / 110455 Summary of the Invention [Problem to be solved by the invention]

[0005] In Patent Document 1, the amount of emission changes naturally depending on the temperature. However, in spaces where the environment is prone to change, such as the interior of a house where people live, a method in which the amount of emission changes naturally as in Patent Document 1 may not be able to respond appropriately to changes in insect activity. If the response to insect activity is low, the inhibitory effect will be weak.

[0006] The object of the present disclosure is to increase the inhibitory effect on insect activity by emitting an inhibitor. [Means for solving the problem]

[0007] The first aspect is directed to an inhibitor dispersing device (70). The device includes a dispersing unit (20, 420) that disperses an inhibitor that inhibits the activity of insects (I) into a target space (S), and a control unit (40) that controls the dispersing unit (20, 420), and the control unit (40) controls the dispersing unit (20, 420) to disperse the inhibitor into the target space (S) in an amount based on information indicating the air conditions in the target space (S).

[0008] In the first aspect, the inhibitor can enhance the inhibitory effect on insects (I) that tend to settle in the target space (S). The activity of the insects (I) that tend to settle in the target space (S) varies depending on the air conditions in the target space (S). By controlling the amount of inhibitor emitted depending on the air conditions, the amount of inhibitor emitted can be increased or decreased depending on the activity of the insects (I), thereby enhancing the inhibitory effect.

[0009] In a second aspect, in the first aspect, the information indicating the air condition includes the temperature in the target space (S) or the humidity in the target space (S).

[0010] In the second aspect, the activity of the insects (I) in the target space (S) can be accurately reflected in the amount of inhibitor emitted, and the inhibitory effect of the inhibitor can be increased.

[0011] In a third aspect, in the second aspect, the temperature in the target space (S) or the humidity in the target space (S) is acquired by a sensor mounted on an air conditioning device (30, 430) installed in the target space (S).

[0012] In the third aspect, the air conditions in the target space (S) can be acquired with high accuracy, and the inhibitory effect of the inhibitor on insects (I) that tend to settle in the target space (S) can be increased.

[0013] In a fourth aspect, in the second or third aspect, the control unit (40) changes the amount of emission into the target space (S) based on the information indicating the air conditions, depending on the type of the target insect (I).

[0014] In the fourth embodiment, the amount of the inhibitor released can be increased when the activity of the target species of insects (I) is high, thereby increasing the inhibitory effect of the inhibitor.

[0015] In a fifth aspect, based on the first aspect, the information indicating the air condition includes operation information of an air conditioning indoor unit (31) installed in the target space (S).

[0016] In the fifth aspect, by using the operation information of the air conditioner indoor unit (31), the activity of the insects (I) can be accurately reflected in the amount of the inhibitor to be emitted, thereby improving the inhibitory effect.

[0017] In a sixth aspect, in any one of the first to fifth aspects, the information indicating the air condition includes a history of information indicating the air condition in the target space (S).

[0018] In the sixth aspect, the state of the target space (S) can be comprehensively determined by taking into consideration not only information indicating the current air condition but also information indicating past air conditions, thereby enabling the current state of the insects (I) to be accurately reflected in the amount of inhibitor released, thereby enhancing the inhibitory effect.

[0019] In a seventh aspect, in any one of the first to sixth aspects, the control unit (40) controls the diffusion unit (20, 420) to diffuse the inhibitor into the target space (S) at a diffusion amount that is set based on information indicating the type of the target space (S) in addition to information indicating the air condition in the target space (S).

[0020] In the seventh aspect, the amount of the inhibitor to be released can be finely adjusted depending on the activity of the insects (I) that tend to settle in each type of target space (S), thereby increasing the inhibitory effect of the inhibitor.

[0021] In an eighth aspect, in the seventh aspect, the information indicating the type of the target space (S) is information estimated based on a detection value of a human detection sensor (65).

[0022] In the eighth aspect, the type of the target space (S) can be determined with high accuracy by detecting the presence or absence of a person in the target space (S) using the human detection sensor (65), thereby enhancing the inhibitory effect of the inhibitor.

[0023] A ninth aspect relates to an inhibitor dispersal system. The inhibitor dispersal system (100, 200, 300, 400, 500) includes an acquisition unit (61, 62, 461, 462) that acquires information indicating air conditions in a target space (S), a dispersal unit (20, 420) that disperses an inhibitor that inhibits the activity of insects (I) into the target space (S), and a control unit (40) that controls the dispersal unit (20, 420), where the control unit (40) controls the dispersal unit (20, 420) to disperse the inhibitor into the target space (S) in an amount based on the information indicating the air conditions acquired by the acquisition unit (61, 62, 461, 462).

[0024] A tenth aspect relates to an inhibitor dispersal method, which includes a first step of acquiring information indicating air conditions in a target space (S), a second step of setting an amount of inhibitor to be dispersed into the target space (S) that inhibits the activity of insects (I) based on the information indicating the air conditions acquired in the first step, and a third step of dispersing the inhibitor into the target space (S) at the amount set in the second step using a dispersion device (20, 420) that disperses the inhibitor.

DETAILED DESCRIPTION OF THE INVENTION

[0026] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. Note that the present disclosure is not limited to the embodiments shown below, and various modifications are possible within the scope of the technical concept of the present disclosure. Since the drawings are intended to conceptually explain the present disclosure, dimensions, ratios, or numbers may be exaggerated or simplified as necessary to facilitate understanding.

[0027] First Embodiment (1) Inhibitor release system FIG. 1 schematically illustrates an inhibitor release system (100) according to the first embodiment. The inhibitor release system is a system for releasing an inhibitor into a target space (S) that inhibits the activity of insects (I) present in the target space (S). The inhibitor release system (100) can create an environment in the target space (S) where the number of insects (I) is reduced by driving away insects (I) that have appeared in the target space (S) or by creating an environment in the target space (S) that is difficult for insects (I) to live in. Here, "inhibiting the activity of insects (I)" includes, for example, actions such as reducing the sensitivity of the olfactory or tactile functions of the insects (I) or inhibiting the reproduction of the insects (I).

[0028] As shown in Figure 1, the target space (S) is an indoor space where people stay, such as a bedroom, living room, kitchen, or office in a house. The target insect species inhibited by the inhibitor release system (100) are, for example, cockroaches, mites, etc. These target insect species (I) are pests that occur relatively frequently in the target space (S) where people live.

[0029] The inhibitor dispersal system (100) of the first embodiment includes an indoor unit (31) of an air conditioner (30), an inhibitor dispersal device (70), and a communication terminal (50).

[0030] The air conditioner (30) adjusts the temperature and humidity of air in the target space (S). The indoor unit (31) is a wall-mounted type. Specifically, the indoor unit (31) is installed on the upper part of an interior wall of a building.

[0031] The inhibitor dissipation device (70) has a dissipation section (20) and a control section (40).

[0032] The communication terminal (50) is a device capable of communicating with the air conditioner (30). The communication terminal (50) includes a remote controller for the air conditioner (30), a smartphone, a tablet terminal, a mobile phone, and the like.

[0033] (1-1) Air conditioner The air conditioner (30) performs cooling operation, heating operation, and dehumidifying operation. In cooling operation, the air conditioner (30) cools the air in the target space (S). In heating operation, the air conditioner (30) heats the air in the target space (S). In dehumidifying operation, the air conditioner (30) reduces the humidity of the air in the target space (S).

[0034] The air conditioner (30) has an indoor unit (31) installed in the target space (S) and an outdoor unit (36) installed outdoors. The indoor unit (31) is connected to the outdoor unit (36) by a refrigerant pipe (37). The air conditioner (30) has a temperature control function. Specifically, the air conditioner (30) cools or heats indoor air using a refrigerant that operates in a refrigeration cycle. This adjusts the temperature of the air in the target space (S). In addition to the temperature control function, the air conditioner (30) has a humidity control function. Specifically, the air conditioner (30) reduces the humidity of the indoor air using a refrigerant that operates in a refrigeration cycle. This adjusts the humidity of the air in the target space (S).

[0035] As shown in Fig. 1, the indoor unit (31) includes an indoor casing (32), an indoor heat exchanger (33), an indoor fan (34), a flap (35), an indoor temperature sensor (61), and an indoor humidity sensor (62). In Fig. 1, the indoor unit (31) is shown in cross section to explain the general configuration of the indoor unit (31).

[0036] The indoor casing (32) is formed in the shape of a horizontally elongated hollow box. The indoor casing (32) has a substantially rectangular cross section. An inlet (32a) is formed in each of the front and top surfaces of the indoor casing (32). An outlet (32b) is formed in the front lower portion of the indoor casing (32).

[0037] The indoor heat exchanger (33) is housed in the indoor casing (32). The indoor heat exchanger (33) functions as a condenser (in heating operation) or an evaporator (in cooling operation) in the refrigerant circuit.

[0038] The indoor fan (34) corresponds to the airflow generating unit of the present disclosure. The indoor fan (34) is housed in the indoor casing (32). The indoor fan (34) is a cross-flow fan. The indoor fan (34) generates an airflow in the target space (S). The indoor fan (34) generates a flow that circulates air throughout the target space (S).

[0039] When the indoor fan (34) is operated, the air blown out from the air outlet (32b) of the indoor unit (31) flows along the floor, wall, and ceiling surfaces facing the target space (S) in that order, and then returns to the air inlet (32a).

[0040] The indoor fan (34) diffuses the air mixed with the inhibitor released from the diffusing section (20) into the target space (S). The inhibitor is mixed in mist form with the airflow generated by the indoor fan (34), and this airflow circulates through the target space (S), thereby distributing the inhibitor throughout the target space (S).

[0041] The flap (35) corresponds to the airflow direction adjusting unit of the present disclosure. The flap (35) is provided at the air outlet (32b) of the indoor unit (31). The flap (35) extends substantially horizontally along the air outlet (32b). The flap (35) is driven to rotate by a motor (not shown). The flap (35) changes the direction of the airflow generated by the indoor fan (34). By changing the position of the flap (35), the air is transported toward, for example, the floor, wall, or ceiling surface facing the target space (S), or specific furniture.

[0042] The indoor temperature sensor (61) detects the temperature in the target space (S). The indoor temperature sensor (61) may detect the temperature in the target space (S) from the temperature of the air taken into the indoor casing (32), or may detect the temperature outside the target space (S) by infrared rays.

[0043] The indoor humidity sensor (62) detects the relative humidity in the target space (S). The indoor humidity sensor (62) detects the humidity in the target space (S) from the relative humidity of the air taken into the indoor casing (32).

[0044] The outdoor unit (36) is installed outside the target space (S). The outdoor unit (36) includes an outdoor casing (36a) and outdoor elements housed in the outdoor casing (36a). The outdoor elements include a compressor, an outdoor heat exchanger, an expansion valve, a four-way selector valve, and an outdoor fan.

[0045] (1-2) Dissipation section The diffusing section (20) diffuses the inhibitor into the target space (S). The diffusing section (20) is housed in the indoor unit (31). The diffusing section (20) is attached to an inner wall of an indoor casing (32) of the indoor unit (31). The diffusing section (20) is disposed, for example, near an air outlet (32b) of the indoor unit (31).

[0046] The diffusion unit (20) of the first embodiment is a spray device that emits a liquid inhibitor in the form of a mist. The diffusion unit (20) of the first embodiment has a spray nozzle, a tank, an air pump, and a flow rate control valve. The tank is connected to the spray nozzle. The liquid inhibitor is stored in the tank. The tank is a cartridge type that can be attached to and detached from the spray nozzle. This allows for easy replacement and replenishment of the inhibitor. One tank or multiple tanks may be provided. The diffusion unit (20) may have multiple tanks that store different types of inhibitors. The inhibitor is not particularly limited, but is, for example, a phenol-based agent.

[0047] The air pump supplies the sucked air to the spray nozzle. A flow rate control valve is provided between the tank and the spray nozzle. The flow rate control valve is configured so that its opening can be changed. By changing the opening rate of the flow rate control valve, the amount of inhibitor released from the release section (20) can be adjusted. The amount of inhibitor released may be adjusted by means other than adjusting the opening rate of the flow rate control valve. For example, the amount of inhibitor released may be adjusted by intermittently operating the air pump.

[0048] The inhibitor used in the present embodiment 1 is an inhibitor that reduces the sensitivity of the olfactory and tactile functions of the insect (I) and inhibits the reproduction of the insect (I). By using an inhibitor that has an inhibitory effect on the insect (I), the impact on human health can be reduced.

[0049] (1-3) Control unit The control unit (40) shown in FIG. 2 controls the diffusing unit (20), the indoor fan (34), and the flap (35). The control unit (40) includes a processor such as a central processing unit (CPU) and a micro processing unit (MPU), an electric circuit, and an electronic circuit. The control unit (40) includes a memory device (specifically, a semiconductor memory) that stores software for operating the processor, etc. In the first embodiment, the control unit (40) also functions as a control device for the air conditioner (30). The control unit (40) may also function as a control device for the communication terminal (50).

[0050] The control unit (40) controls the diffusing unit (20) so that the inhibitor is diffused into the target space (S) at a diffusion amount set based on the air conditions of the target space (S). The control unit (40) adjusts the amount of the inhibitor diffused by controlling a flow rate control valve of the diffusing unit (20).

[0051] The control unit (40) has a first communication unit (41), a determination unit (42), and a storage unit (43) as functional units. The first communication unit (41) is connected to the communication terminal (50), the indoor temperature sensor (61), and the indoor humidity sensor (62) via a wired or wireless communication line. The first communication unit (41) is connected to other devices by wireless communication via, for example, a wireless router. The first communication unit (41) includes a receiving unit that receives detection values ​​transmitted from the indoor temperature sensor (61) and the indoor humidity sensor (62). The first communication unit (41) includes a transmitting unit that transmits information about the insect (I) to the communication terminal (50).

[0052] The determination unit (42) determines the amount of inhibitors radiated into the target space (S) based on the air conditions of the target space (S). In the first embodiment, the determination unit (42) determines the amount of inhibitors radiated into the target space (S) from the detected values ​​of the room temperature sensor (61) and the room humidity sensor (62) received by the first communication unit (41). The processing of the determination unit (42) will be described in detail later.

[0053] The storage unit (43) stores operation information of the air conditioner (30) and determination information of the determination unit (42). The storage unit (43) is formed by the memory device.

[0054] (1-4) Communication terminal The communication terminal (50) is a terminal operated by a person. The communication terminal (50) includes a microcomputer and a memory device. The memory device stores software for operating the microcomputer. The communication terminal (50) has an operation unit (51), a notification unit (52), and a second communication unit (53) as functional units.

[0055] The operation unit (51) of the first embodiment is configured with a touch panel of the communication terminal (50). A person can operate the application software stored in the communication terminal (50) using the operation unit (51) to activate or stop the inhibitor release system (100) and cause the notification unit (52) to display information about insects.

[0056] The notification unit (52) notifies information about insects present in the target space (S). The notification unit (52) of the first embodiment is configured with a liquid crystal panel of the communication terminal (50). The information about insects (I) displayed on the notification unit (52) includes the likelihood of insect (I) occurrence in the target space (S). The information about insects (I) may be displayed when a command to display information about insects (I) is sent from the operation unit (51) to the control unit (40).

[0057] The second communication unit (53) includes a transmitting unit that transmits commands input through the operation unit (51) to the control unit (40). The second communication unit (53) includes a receiving unit that receives information about the insect (I) transmitted from the control unit (40).

[0058] (2) Air conditions In the first embodiment, the air conditions of the target space (S) used for the determination by the determination unit (42) include the temperature (indoor temperature) of the target space (S) and the humidity (indoor humidity) of the target space (S). The air conditions include not only the current air conditions but also past air conditions in the same target space (S), i.e., the history of air conditions. In the first embodiment, the temperature of the target space (S) is a value detected by the indoor temperature sensor (61), and the humidity of the target space (S) is a value detected by the indoor humidity sensor (62). The indoor temperature sensor (61) and the indoor humidity sensor (62) constitute an acquisition unit.

[0059] The determination unit (42) sets a high emission rate when the air conditions in the target space (S) are conducive to the propagation of the target type of insect (I), and sets a low emission rate when the air conditions in the target space (S) are conducive to the propagation of the target type of insect (I). The determination unit (42) sets the emission rate of the inhibitor using an activity flag indicating that the air conditions in the target space (S) are conducive to the propagation of the insects (I). The conditions conducive to the propagation of the insects (I) differ depending on the type of insect (I). The determination unit (42) uses multiple activity flags to accommodate multiple types of insects (I). The determination unit (42) determines whether each activity flag is on or off based on the detected values ​​of the indoor temperature sensor (61) and the indoor humidity sensor (62). Below, a first activity flag, a second activity flag, and a third activity flag will be described as examples of the activity flags used by the determination unit (42).

[0060] (2-1) First active flag The first activation flag is set to on or off based on the values ​​detected by the room temperature sensor 61 and the room humidity sensor 62. The first activation flag is set to on or off at regular intervals, which may be, for example, one hour.

[0061] As shown in FIG. 3, in step ST101, the determination unit (42) determines whether the room temperature (T I ) is the first predetermined temperature (T C The determination unit (42) determines whether the room temperature (T I ) is the first predetermined temperature (T C If the result is YES, that is, if the result is equal to or greater than 1), the process proceeds to step ST102. I ) is the first predetermined temperature (T C If the result is NO, that is, if the temperature is less than the first predetermined temperature (T C 1) is not particularly limited, but is, for example, 23°C.

[0062] In step ST102, the indoor humidity (H I ) is the first predetermined humidity (H CThe determining section (42) determines whether the indoor humidity (H I ) is the first predetermined humidity (H C If the answer is YES, that is, if the answer is YES, the process proceeds to step ST103. I ) is the first predetermined humidity (H C If the result is NO, that is, if the humidity is less than the first predetermined humidity (H C 1) is not particularly limited, but is, for example, 65%.

[0063] In step ST103, the determination unit (42) turns on the first active flag. In step ST104, the determination unit (42) turns off the first active flag. The determination result of the first active flag by the determination unit (42) is stored in the storage unit (43). After steps ST103 and ST104, the process returns.

[0064] It should be noted that it does not matter which of the temperature (step ST101) and the humidity (step ST102) is determined first, or the order may be reversed.

[0065] (2-2) Second active flag and third active flag The second and third activity flags are determined to be on or off based on the values ​​detected by the room temperature sensor (61) and the room humidity sensor (62). The on or off determination of the second and third activity flags is performed at regular intervals. The regular interval is, for example, one hour.

[0066] As shown in FIG. 4, in step ST201, the determination unit (42) determines the room temperature (T I ) is the second predetermined temperature (T C The determination unit (42) determines whether the room temperature (T I ) is the second predetermined temperature (T C If the answer is YES, that is, if the answer is YES, the process proceeds to step ST202. I ) is the second predetermined temperature (T C If the result is NO, that is, if the temperature is less than the second predetermined temperature (T C2) is not particularly limited, but is, for example, 23°C.

[0067] In step ST202, the determination unit (42) determines the indoor humidity (H I ) is the second predetermined humidity (H C The determining section (42) determines whether the indoor humidity (H I ) is the second predetermined humidity (H C If the answer is YES, that is, if the answer is YES, the process proceeds to step ST203. I ) is the second predetermined humidity (H C If the result is NO, that is, if the humidity is less than the second predetermined humidity (H C 2) is not particularly limited, but is, for example, 65%.

[0068] In step ST203, the indoor temperature (T I ) is the third predetermined temperature (T C The determination unit (42) determines whether the room temperature (T I ) is the third predetermined temperature (T C If the result is YES, that is, if the result is equal to or greater than 3), the process proceeds to step ST204. I ) is the third predetermined temperature (T C If the result is NO, that is, if the temperature is less than the third predetermined temperature (T C 3) is the second predetermined temperature (T C There are no particular limitations on the temperature as long as it is higher than 2), and it is, for example, 26°C.

[0069] In step ST204, the determination unit (42) turns on both the second active flag and the third active flag. In step ST205, the determination unit (42) turns on the second active flag and turns off the third active flag. In step ST206, the determination unit (42) turns off both the second active flag and the third active flag. The determination results of the second active flag and the third active flag by the determination unit (42) are stored in the storage unit (43). After steps ST204, ST205, and ST206, the process returns.

[0070] (3) Emission control Next, the operation of the inhibitor release system (100) will be described. The operation of the inhibitor release system (100) includes a release mode. The release mode has a first insect species mode and a second insect species mode. The first insect species mode is a mode that mainly targets cockroaches. The second insect species mode is a mode that mainly targets mites. Whether the release mode is the first insect species mode or the second insect species mode may be selected, for example, by the communication terminal (50), or may be set in advance at the stage of installing the indoor unit (31) in the target space (S).

[0071] (3-1) First insect mode In the first insect species mode, the determination section (42) of the control section (40) uses the first activity flag to set the amount of inhibitor release.

[0072] In the first insect species mode, the determination unit 42 selects one of "no emission required," "first emission amount," and "second emission amount." "No emission required" means that there is no need to emit the inhibitor, and the emission amount is set to 0. The first emission amount is greater than the second emission amount.

[0073] When the inhibitor diffusion system (100) starts operating, the control unit (40) turns on the indoor fan (34). The indoor fan (34) generates an airflow that circulates air throughout the target space (S). The control unit (40) keeps the indoor fan (34) on until the inhibitor diffusion system (100) stops operating.

[0074] After the indoor fan (34) is turned on, the determination section (42) of the control section (40) checks the history of the first activation flag in step ST301, as shown in Fig. 5. The determination section (42) reads the history of the first activation flag from the storage section (43).

[0075] In the next step ST302, the determination unit (42) determines whether the number of times the first activity flag is turned on during a predetermined period is equal to or greater than a first predetermined ratio. The determination unit (42) makes the determination by comparing the number of times the first activity flag is determined to be on during the predetermined period with the number of times the first activity flag is determined to be on. If the determination result is YES, that is, the number of times the first activity flag is turned on is equal to or greater than the first predetermined ratio, the determination unit (42) proceeds to step ST303. If the determination result is NO, that is, the number of times the first activity flag is turned on is less than the first predetermined ratio, the determination unit (42) proceeds to step ST304. The predetermined period is not particularly limited, but may be, for example, 72 hours. The first predetermined ratio is not particularly limited, but may be, for example, 1 / 3.

[0076] In step ST303, the determination unit (42) determines whether the number of times the first active flag has been turned on during a predetermined period is equal to or greater than a second predetermined rate. If the determination result is YES, that is, the number of times the first active flag has been turned on is equal to or greater than the second predetermined rate, the determination unit (42) proceeds to step ST305. If the determination result is NO, that is, the number of times the first active flag has been turned on is less than the second predetermined rate, the determination unit (42) proceeds to step ST306. The second predetermined rate is not particularly limited as long as it is greater than the first predetermined rate, but is, for example, 2 / 3.

[0077] In step ST304, the determining section 42 determines that release is not necessary, and the control section 40 stops release of the inhibitor from the release section 20.

[0078] In step ST305, the determination unit (42) determines that the amount of emission should be the first amount of emission. The control unit (40) controls the emission unit (20) so that the amount of the inhibitor emitted into the target space (S) becomes the first amount of emission. After step ST305, the process returns.

[0079] In step ST306, the determination unit (42) determines that the amount of emission should be the second amount of emission. The control unit (40) controls the emission unit (20) so that the amount of the inhibitor emitted into the target space (S) becomes the second amount of emission. After step ST306, the process returns.

[0080] (3-2) Second insect species mode Mites, which are the target of the second insect species mode, tend to multiply when the indoor temperature and humidity are high. In the second insect species mode, the determination unit (42) of the control unit (40) uses the second activity flag and the third activity flag to set the amount of inhibitor to be emitted.

[0081] The determination unit (42) selects one of no emission required, the third emission amount, the fourth emission amount, the fifth emission amount, and the sixth emission amount. No emission required is the same as the first insect species mode described above. The third emission amount is the smallest of the third to sixth emission amounts. The sixth emission amount is the largest of the third to sixth emission amounts. The fourth and fifth emission amounts are amounts between the third and sixth emission amounts, with the fifth emission amount being larger than the fourth emission amount.

[0082] When the inhibitor diffusion system (100) starts operating, the control unit (40) turns on the indoor fan (34). The indoor fan (34) generates an airflow that circulates air throughout the target space (S). The control unit (40) keeps the indoor fan (34) on until the inhibitor diffusion system (100) stops operating.

[0083] After the indoor fan (34) is turned on, the determination section (42) of the control section (40) checks the history of the second activation flag in step ST401, as shown in Fig. 6. The determination section (42) reads the history of the second activation flag from the storage section (43).

[0084] In the next step ST402, the determination unit (42) determines whether the number of times the second activity flag is turned on during a predetermined period is equal to or greater than a third predetermined rate. The determination unit (42) makes the determination by comparing the number of times the second activity flag is determined to be on during the predetermined period with the number of times the second activity flag is determined to be on. If the determination result is YES, that is, the number of times the second activity flag is turned on is equal to or greater than the third predetermined rate, the determination unit (42) proceeds to step ST403. If the determination result is NO, that is, the number of times the second activity flag is turned on is less than the third predetermined rate, the determination unit (42) proceeds to step ST407. The predetermined period is not particularly limited, but may be, for example, 72 hours. The third predetermined rate is not particularly limited, but may be, for example, 1 / 10.

[0085] In step ST403, the determination unit 42 determines whether the number of times the second active flag is turned on during a predetermined period is equal to or greater than a fourth predetermined rate. If the result is YES, that is, the number of times the second active flag is turned on is equal to or greater than the fourth predetermined rate, the determination unit 42 proceeds to step ST404. If the result is NO, that is, the number of times the second active flag is turned on is less than the fourth predetermined rate, the determination unit 42 proceeds to step ST408. The fourth predetermined rate is not particularly limited, but may be, for example, 1 / 5.

[0086] In step ST404, the determination unit 42 determines whether the number of times the second active flag is turned on during a predetermined period is equal to or greater than a fifth predetermined rate. If the result is YES, that is, the number of times the second active flag is turned on is equal to or greater than the fifth predetermined rate, the determination unit 42 proceeds to step ST405. If the result is NO, that is, the number of times the second active flag is turned on is less than the fifth predetermined rate, the determination unit 42 proceeds to step ST409. The fifth predetermined rate is not particularly limited, but may be, for example, 1 / 2.

[0087] In step ST405, the determination unit (42) checks the history of the third activation flag and reads out the history of the third activation flag from the storage unit (43).

[0088] In the next step ST406, the determination unit (42) determines whether the number of times the third active flag is turned on during a predetermined period is equal to or greater than a sixth predetermined rate. The determination unit (42) makes this determination by comparing the number of times the third active flag is determined to be on or off during the predetermined period with the number of times the third active flag is determined to be on. If the determination result is YES, that is, the number of times the third active flag is turned on is equal to or greater than the sixth predetermined rate, the determination unit (42) proceeds to step ST411. If the determination result is NO, that is, the number of times the third active flag is turned on is less than the sixth predetermined rate, the determination unit (42) proceeds to step ST410. The sixth predetermined rate is not particularly limited, but may be, for example, 1 / 2.

[0089] In step ST407, the determining section 42 determines that release is not necessary, and the control section 40 stops release of the inhibitor from the release section 20.

[0090] In step ST408, the determination unit (42) determines that the amount of emission should be set to the third amount of emission. The control unit (40) controls the emission unit (20) so that the amount of the inhibitor emitted into the target space (S) becomes the third amount of emission. After step ST408, the process returns.

[0091] In step ST409, the determination unit (42) determines that the amount of emission should be set to the fourth amount of emission. The control unit (40) controls the emission unit (20) so that the amount of the inhibitor emitted into the target space (S) becomes the fourth amount of emission. After step ST409, the process returns.

[0092] In step ST410, the determination unit (42) determines that the emission amount should be the fifth emission amount. The control unit (40) controls the emission unit (20) so that the emission amount of the inhibitor into the target space (S) becomes the fifth emission amount. After step ST410, the process returns.

[0093] In step ST411, the determination unit (42) determines that the amount of emission should be set to the sixth amount of emission. The control unit (40) controls the emission unit (20) so that the amount of the inhibitor emitted into the target space (S) becomes the sixth amount of emission. After step ST411, the process returns.

[0094] (3) Effects of the First Embodiment In the inhibitor release device (70) of the inhibitor release system (100) according to the first embodiment, the control unit (40) controls the release unit (20) to release the inhibitor into the target space (S) at an amount based on information indicating the air conditions of the target space (S). The activity of insects (I) that tend to settle in the target space (S) varies depending on the air conditions of the target space (S). In particular, the reproductive potential of insects (I) is affected by the air conditions of the target space (S). Insects (I) tend to settle in spaces with air conditions that promote their activity. Therefore, by controlling the amount of inhibitor release based on the air conditions of the target space (S), the amount of release can be increased or decreased depending on the activity of the insects (I), thereby enhancing the inhibitory effect.

[0095] In the first embodiment, the information indicating the air conditions includes the temperature and humidity in the target space (S). The temperature and humidity in the target space (S) are likely to affect the activity of the insects (I). Therefore, the activity of the insects (I) in the target space (S) can be accurately reflected in the amount of inhibitor emitted, thereby enhancing the inhibitory effect of the inhibitor.

[0096] In the first embodiment, the indoor temperature and indoor humidity are acquired by sensors (61, 62) mounted on an indoor unit (31) installed in the target space (S). The air conditions in the target space (S) can be acquired with high accuracy, and the inhibitor can enhance the inhibitory effect on insects (I) that tend to settle in the target space (S).

[0097] In the first embodiment, the amount of inhibitor emission is determined taking into account the history of air conditions in the target space (S). This allows the state of the target space (S) to be determined comprehensively. Furthermore, the past state of the insects (I) in the target space (S) can be accurately reflected in the amount of inhibitor emission. For example, if high temperature and high humidity air conditions that induce insect (I) activity have continued for several days, it is highly likely that the insects (I) are now active and facilitating reproduction. By taking into account the history of air conditions, the current state of the insects (I) can be accurately reflected in the amount of inhibitor emission, thereby increasing the inhibitory effect of the inhibitor.

[0098] In the first embodiment, the control unit (40) changes the amount of inhibitor released into the target space (S) based on information indicating air conditions, depending on the type of target insect (I). For example, as illustrated in the cases of cockroaches and mites, the temperature and humidity at which the insect (I) becomes active differ depending on the type of insect (I). In the first embodiment, the activity status of each type of insect (I) can be determined, and the amount of inhibitor released can be increased when the activity of the target type of insect (I) is high. This increases the inhibitory effect of the inhibitor.

[0099] (4) Variations The first embodiment may be modified as follows: In the following explanation, differences from the first embodiment will be mainly explained.

[0100] (4-1) Variation 1: Use information on the type of target space The inhibitor dissipation system (100) according to the first modification further uses information on the type of the target space (S) in addition to the air conditions of the target space (S). The information on the type of the target space (S) may be registered in advance when the dissipation unit (20) is installed, or may be estimated as in the second and third modifications described below.

[0101] In the present first modification, the determination unit (42) determines which mode to select as the dispersal mode based on information on the type of the target space (S). For example, when the target space (S) is a living room, kitchen, office, etc., the determination unit (42) selects the first insect species mode that targets cockroaches. On the other hand, when the target space (S) is a bedroom, the determination unit (42) selects the second insect species mode that targets dust mites.

[0102] When the target space (S) is a living room, kitchen, or office, cockroaches tend to settle in the gaps between furniture and office equipment, so it is preferable to take measures against cockroaches. On the other hand, when the target space (S) is a bedroom, mites tend to breed there, so it is preferable to take measures against mites. By further utilizing information on the type of target space (S) as in this first modification, the amount of inhibitor released can be finely adjusted according to the activity of the insects (I) that tend to settle in each type of target space (S). This increases the inhibitory effect of the inhibitor.

[0103] (4-2) Variation 2: Using driving information In the inhibitor release system (100) according to the second modification, the determination unit (42) uses the operation information of the indoor unit (31) to determine the amount of release of the inhibitor. The operation information of the indoor unit (31) is stored in the memory unit (43) of the control unit (40).

[0104] The determination unit (42) estimates, for example, the type of the target space (S) from the operation information of the air conditioner (30).

[0105] FIG. 7 shows an example of the operation history of the indoor units (31) on a weekday. The first indoor unit, the second indoor unit, and the third indoor unit are independent indoor units (31). The first indoor unit operates in the morning and in the evening to night, and does not operate during the day or late at night. It can be estimated that the space in which the first indoor unit is installed is a space in which people are present mainly in the morning and in the evening to night, and no people are present during the day or late at night. From this, it can be estimated, for example, that the space in which the first indoor unit is installed is a living room or a kitchen. The second indoor unit operates in the evening to early morning, and does not operate during the day to evening. It can be estimated that the space in which the second indoor unit is installed is a space in which people are present mainly during the night, and no people are present during the day to evening. From this, it can be estimated, for example, that the space in which the second indoor unit is installed is a bedroom. The third indoor unit operates in the day to evening, and does not operate during the night to early morning. It can be estimated that the space in which the third indoor unit is installed is a space in which people are present mainly during the day to evening, and no people are present during the night to early morning. From this, it can be inferred that the space in which the third indoor unit is installed is an office, for example.

[0106] The determination unit 42 determines the amount of inhibitor release, further taking into consideration the type of the estimated target space S. The determination unit 42 determines the type of insects I to be inhibited, specifically, the release mode to be adopted, from the type of target space S.

[0107] 8, in step ST501, the determination section (42) of the control section (40) checks the operation history of the indoor unit (31). The determination section (42) reads out the operation history of the indoor unit (31) from the storage section (43).

[0108] In step ST502, the determination unit (42) determines whether the operating time in the evening to night during a predetermined period is equal to or longer than a first predetermined time. If the determination result is YES, that is, the operating time in the evening to night is equal to or longer than the first predetermined time, the determination unit (42) proceeds to step ST503. If the determination result is NO, that is, the operating time in the evening to night is less than the first predetermined time, the determination unit (42) proceeds to step ST505. The first predetermined time is not particularly limited, but is, for example, 12 hours. The evening is, for example, 4:00 PM to 7:00 PM. The night is, for example, 7:00 PM to 11:00 PM.

[0109] In step ST503, the determination unit 42 estimates that the target space (S) is a living room or a kitchen. In the next step ST504, the determination unit 42 sets the release mode to a first insect species mode targeting cockroaches. After step ST504, the process returns.

[0110] On the other hand, in step ST505, it is determined whether or not the daytime operating time during the predetermined period is equal to or longer than a second predetermined time. If the result is YES, that is, the daytime operating time is equal to or longer than the second predetermined time, the determination unit (42) proceeds to step ST506. If the result is NO, that is, that the daytime operating time is shorter than the second predetermined time, the determination unit (42) proceeds to step ST508. The second predetermined time is not particularly limited, but is, for example, 10 hours. Daytime is, for example, from 10:00 to 16:00.

[0111] In step ST506, the determination unit 42 estimates that the target space (S) is an office. In the next step ST507, the determination unit 42 sets the dispersal mode to the first insect species mode targeting cockroaches. After step ST507, the process returns.

[0112] In the next step ST508, the determination unit (42) determines whether or not the late-night operating time during the predetermined period is equal to or longer than a third predetermined time. If the result is YES, that is, the late-night operating time is equal to or longer than the third predetermined time, the determination unit (42) proceeds to step ST509. If the result is NO, that is, the late-night operating time is less than the third predetermined time, the determination unit (42) proceeds to step ST511. The predetermined period is not particularly limited, but is, for example, 72 hours. The third predetermined time is not particularly limited, but is, for example, 10 hours. Late night is, for example, from 11:00 PM to 5:00 AM the next day.

[0113] In step ST509, the determination unit 42 estimates that the target space (S) is a bedroom. In the next step ST510, the determination unit 42 sets the release mode to the second insect species mode targeting mites. After step ST510, the process returns.

[0114] In step ST511, the determination unit (42) determines that the release is not necessary. This is because the space in which the air conditioner (30) is not operating during the daytime to late night hours is presumed to be a space that is not used on a daily basis, and therefore it is determined that the release of the inhibitor is not necessary.

[0115] The operation of the inhibitor diffusion system (100) after the diffusion mode is set is the same as that of the first embodiment, and therefore a detailed description thereof will be omitted.

[0116] As described above, in the present second modification, the control unit (40) controls the radiator (20) in consideration of the operation information of the indoor unit (31) and the information on the type of the target space (S) estimated from the operation information. By using the information on the type of the target space (S), the amount of the inhibitor to be radiated can be finely adjusted according to the activity of the insects (I) that tend to settle in each type of target space (S). This increases the inhibitory effect of the inhibitor.

[0117] In the present modified example 2, the amount of inhibitor released may be adjusted depending on the stop period of the indoor unit (31). For example, if the stop period is longer than a certain period, the amount of inhibitor released when the indoor unit (31) is operated for the first time after the stop period may be set to be larger than that when the stop period is shorter than the certain period.

[0118] (4-3) Variation 3: Use of a human detection sensor In the inhibitor release system (200) according to the third modification, as shown in FIG. 9 , the determination unit (42) uses the detection value of the human detection sensor (65) to determine the amount of release of the inhibitor. The human detection sensor (65) detects people present in the target space (S). The human detection sensor (65) may detect the number of people or the number of people. The human detection sensor (65) is, for example, an infrared sensor. The human detection sensor (65) is attached, for example, near the air outlet (32b) of the indoor unit (31). The detection value of the human detection sensor (65) is input to the control unit (40) and stored in the memory unit (43) of the control unit (40).

[0119] The determination unit (42) estimates, for example, the type of the target space (S) from the detection result of the human detection sensor (65), for example.

[0120] FIG. 10 shows an example of the detection results of the human detection sensor (65) on a weekday. The first sensor, the second sensor, and the third sensor are each independent human detection sensors (65). The values ​​on the vertical axis indicate the number of people simultaneously detected by the human detection sensors (65). The first sensor detected three people in the morning and in the evening to night, and detected no people during the day or late at night. It can be inferred that the space in which the first sensor is placed is a space where many people are present mainly in the morning and in the evening to night, and no people are present during the late night. From this, it can be inferred, for example, that the space in which the first sensor is placed is a living room. The second sensor detected one person during the night to early morning, and no people are present during the day. It can be inferred that the space in which the second sensor is placed is a space where a small number of people are present during the night to early morning, and no people are present during the day. From this, it can be inferred, for example, that the space in which the second sensor is placed is a bedroom. The third sensor detected four or more people during the day to evening, and no people are present during the night to early morning. It can be estimated that the space where the third sensor is placed is a space where many people are present mainly in the daytime and evening, and no one is present at night or early in the morning. From this, it can be estimated that the space where the third sensor is placed is an office, for example. In addition, it can also be estimated that a space where a small number of people are present in the evening or night is a kitchen, for example.

[0121] The determination unit 42 determines the amount of inhibitor release, further taking into consideration the type of the estimated target space S. The determination unit 42 determines the type of insects I to be inhibited, specifically, the release mode to be adopted, from the type of target space S.

[0122] 11, in step ST601, the determination unit (42) of the control unit (40) checks the detection history of the human detection sensor (65). The determination unit (42) reads the detection history of the human detection sensor (65) from the storage unit (43).

[0123] In the next step ST602, the determination unit (42) determines whether the rate at which four or more people are detected during a predetermined period is equal to or greater than a seventh predetermined rate. The determination unit (42) makes this determination, for example, by comparing the total number of people detected with the number of people detected that is four or more. If the determination result is YES, that is, the rate at which four or more people are detected is equal to or greater than the seventh predetermined rate, the determination unit (42) proceeds to step ST603. If the determination result is NO, that is, the rate at which four or more people are detected is less than the seventh predetermined rate, the determination unit (42) proceeds to step ST605. The predetermined period is not particularly limited, but may be, for example, 72 hours. The seventh predetermined rate is not particularly limited, but may be, for example, 1 / 3.

[0124] In step ST603, the determination unit 42 estimates that the target space (S) is an office. In the next step ST604, the determination unit 42 sets the release mode to the first insect species mode targeting cockroaches. After step ST604, the process returns.

[0125] In the next step ST605, the determination unit (42) determines whether the rate at which people are detected in the evening to night during a predetermined period is equal to or greater than an eighth predetermined rate. The determination unit (42) makes this determination, for example, by comparing the total number of people detected with the number of people detected in the evening to night. If the determination result is YES, that is, the rate at which people are detected in the evening to night is equal to or greater than the eighth predetermined rate, the determination unit (42) proceeds to step ST606. If the determination result is NO, that is, the rate at which people are detected in the evening to night is less than the eighth predetermined rate, the determination unit (42) proceeds to step ST608. The eighth predetermined rate is not particularly limited, but may be, for example, 1 / 4.

[0126] In step ST603, the determination unit 42 estimates that the target space (S) is a living room or a kitchen. In the next step ST604, the determination unit 42 sets the release mode to a first insect species mode targeting cockroaches. After step ST604, the process returns.

[0127] On the other hand, in step ST608, it is determined whether the rate at which people were detected late at night during the predetermined period is equal to or greater than a ninth predetermined rate. The determination unit (42) makes this determination, for example, by comparing the total number of people detected with the number of people detected late at night. If the determination result is YES, that is, the rate at which people were detected late at night is equal to or greater than the ninth predetermined rate, the determination unit (42) proceeds to step ST609. If the determination result is NO, that is, the rate at which people were detected late at night is less than the ninth predetermined rate, the determination unit (42) proceeds to step ST611. The ninth predetermined rate is not particularly limited, but may be, for example, 1 / 3.

[0128] In step ST609, the determination unit 42 estimates that the target space (S) is a bedroom. In the next step ST610, the determination unit 42 sets the release mode to the second insect species mode targeting mites. After step ST610, the process returns.

[0129] In step ST611, the decision section (42) decides that emission is not necessary.

[0130] The operation of the inhibitor diffusion system (200) after the diffusion mode is set is the same as that of the first embodiment, and therefore a detailed description thereof will be omitted.

[0131] As described above, in the present third modification, the type of the target space (S) is estimated based on the detection value of the human detection sensor (65). By using the information on the type of the target space (S), the amount of the inhibitor to be released can be finely adjusted according to the activity of the insects (I) that tend to settle in each type of target space (S). This increases the inhibitory effect of the inhibitor.

[0132] In the third modification, the amount of emitted inhibitor may be adjusted according to the number of people detected by the human detection sensor 65. For example, the amount of emitted inhibitor may be increased as the number of people detected increases.

[0133] (4-4) Modification 4: Configuration including a server device In the inhibitor release system (300) according to the fourth modification, the control of the release amount is realized by using cloud computing. As shown in FIG. 12 , in the inhibitor release system (300), the determination unit (82) is not provided in the control unit (40) but in the server device (80). The server device (80) includes a third communication unit (81) in addition to the determination unit (82). The server device (80) can communicate with the control unit (40) via a network.

[0134] The control unit (40) transmits the operation information of the air conditioner (30) and the sensor values ​​to the server device (80) via the first communication unit (41). The server device (80) acquires the operation information of the air conditioner (30) and the sensor values ​​via the third communication unit (81). The server device (80) determines the emission mode to be adopted and the amount of inhibitor emission via the determination unit (82). The server device (80) transmits the determination result of the determination unit (82) to the control unit (40) via the third communication unit (81). The control unit (40) controls the emission unit (20) to emit the inhibitor into the target space (S) at an amount based on the determination result.

[0135] In the fourth modification, the determination unit (82) is arranged in the server device (80). Since the degree of freedom in design of the determination unit (82) is increased, the calculation capacity of the determination unit (82) can be increased. Since the determination accuracy of the determination unit (82) is increased, the amount of emitted inhibitor can be finely adjusted. This increases the inhibitory effect of the inhibitor.

[0136] (4-5) Variation 5: Adoption in air purifiers In an inhibitor dissipation system (400) according to the fifth modification, the dissipation section (420) is arranged in an air purifier (430) serving as an air conditioner, as shown in Fig. 13. The air purifier (430) includes, in addition to the dissipation section (420), an indoor temperature sensor (461) that detects the temperature in the target space (S) and an indoor humidity sensor (462) that detects the relative humidity in the target space (S).

[0137] The operation of the inhibitor diffusion system (400) is the same as that of the first embodiment, and therefore a detailed description thereof will be omitted.

[0138] Even if the diffusing section (420) is arranged in the air purifier (430) as in Modification 5, the amount of inhibitor diffusing can be actively controlled based on the air conditions in the target space (S). The air purifier (430) has a higher degree of freedom in installation compared to an indoor unit, and therefore can diffusing inhibitors to various target spaces (S).

[0139] Second Embodiment A second embodiment of the present disclosure will be described in detail with reference to the drawings. In the following description, parts common to the first embodiment will be denoted by the same reference numerals, and detailed description thereof will be omitted.

[0140] (5) Control unit 14, the inhibitor dispersal system (500) according to the second embodiment does not include an indoor temperature sensor (61) or an indoor humidity sensor (62). The determination unit (42) of the control unit (40) determines the amount of inhibitor to be sprayed without using the detected values ​​of the indoor temperature sensor (61) and the indoor humidity sensor (62). Note that the fact that the inhibitor dispersal system (500) does not include the indoor temperature sensor (61) or the indoor humidity sensor (62) does not negate the fact that the indoor unit (31) may have an indoor temperature sensor and an indoor humidity sensor for use in controlling air conditioning.

[0141] (6) Emission control The release modes implemented by the inhibitor release system (500) include a first insect species mode and a second insect species mode, as in the first embodiment described above. The first insect species mode is a mode that mainly targets cockroaches. The second insect species mode is a mode that mainly targets mites. Whether the release mode is the first insect species mode or the second insect species mode may be determined by the determination unit (42) based on the operating information of the indoor unit (31), for example, as described above (see FIG. 8).

[0142] The determination section (42) determines the amount of inhibitor to be sprayed in each of the first insect species mode and the second insect species mode by comprehensively determining the operation information of the indoor unit (31), particularly the operation history.

[0143] (6-1) First insect mode When the inhibitor diffusion system (500) starts operating, the control unit (40) turns on the indoor fan (34). The indoor fan (34) generates an airflow that circulates air throughout the target space (S). The control unit (40) keeps the indoor fan (34) on until the inhibitor diffusion system (100) stops operating.

[0144] After the indoor fan (34) is turned on, the decision section (42) of the control section (40) checks the operation history of the indoor unit (31) in step ST701, as shown in FIG.

[0145] In the next step ST702, the determination unit (42) determines whether or not a cooling operation has been performed during a predetermined period. If the determination result is YES, that is, a cooling operation has been performed during the predetermined period, the determination unit (42) proceeds to step ST703. If the determination result is NO, that is, that a cooling operation has not been performed during the predetermined period, the determination unit (42) proceeds to step ST704. The predetermined period is not particularly limited, but may be, for example, 72 hours. The cooling operation includes a cooling and dehumidifying operation in which a cooling operation and a dehumidifying operation are performed simultaneously.

[0146] In the next step ST703, the determination unit (42) determines the set temperature (T S ) is the fourth predetermined temperature (T C The determination unit (42) determines whether the temperature is equal to or lower than the set temperature (T S ) is the fourth predetermined temperature (T C If the result is YES, that is, if the temperature is equal to or lower than the set temperature (T S ) is the fourth predetermined temperature (T C If the result is NO and the temperature is greater than the fourth predetermined temperature (T C 4) is not particularly limited, but is, for example, 27° C. When the cooling operation is performed multiple times during a predetermined period or when the set temperature is changed during the cooling operation, the determination unit (42) may make a determination based on the average value of the set temperatures.

[0147] In step ST704, the determining section 42 determines that release is not necessary, and the control section 40 stops release of the inhibitor from the release section 20.

[0148] In step ST705, the determination unit (42) determines that the amount of emission should be the first amount of emission. The control unit (40) controls the emission unit (20) so that the amount of the inhibitor emitted into the target space (S) becomes the first amount of emission. After step ST705, the process returns.

[0149] In step ST706, the determination unit (42) determines that the amount of emission should be the second amount of emission. The control unit (40) controls the emission unit (20) so that the amount of the inhibitor emitted into the target space (S) becomes the second amount of emission. After step ST706, the process returns.

[0150] (6-2) Second Insect Mode When the inhibitor diffusion system (100) starts operating, the control unit (40) turns on the indoor fan (34). The indoor fan (34) generates an airflow that circulates air throughout the target space (S). The control unit (40) keeps the indoor fan (34) on until the inhibitor diffusion system (100) stops operating.

[0151] After the indoor fan (34) is turned on, the decision section (42) of the control section (40) checks the operation history of the indoor unit (31) in step ST801, as shown in FIG.

[0152] In the next step ST802, the determination unit (42) determines whether or not a dehumidifying operation has been performed during a predetermined period. If the determination result is YES, that is, that a dehumidifying operation has been performed during the predetermined period, the determination unit (42) proceeds to step ST803. If the determination result is NO, that is, that a dehumidifying operation has not been performed during the predetermined period, the determination unit (42) proceeds to step ST805. The predetermined period is not particularly limited, but may be, for example, 72 hours. The dehumidifying operation includes a cooling and dehumidifying operation in which a cooling operation and a dehumidifying operation are performed simultaneously.

[0153] In the next step ST803, the determination unit (42) determines whether or not a cooling operation has been performed during a predetermined period. If the determination result is YES, that is, a cooling operation has been performed during the predetermined period, the determination unit (42) proceeds to step ST804. If the determination result is NO, that is, that a cooling operation has not been performed during the predetermined period, the determination unit (42) proceeds to step ST807. The cooling operation includes a cooling and dehumidifying operation in which a cooling operation and a dehumidifying operation are performed simultaneously.

[0154] In the next step ST804, the determination unit (42) determines the set temperature (T S ) is the fifth predetermined temperature (T C The determination unit (42) determines whether the temperature is equal to or lower than the set temperature (T S ) is the fifth predetermined temperature (T C If the result is YES, that is, if the temperature is equal to or lower than the set temperature (T S ) is the fifth predetermined temperature (T C If the result is NO and the temperature is greater than the fifth predetermined temperature (T C 5) is not particularly limited, but is, for example, 25° C. When the cooling operation is performed multiple times during a predetermined period or when the set temperature is changed during the cooling operation, the determination unit (42) may make a determination based on the average value of the set temperatures.

[0155] In step ST805, the determination unit (42) determines whether or not a cooling operation has been performed during a predetermined period. If the determination result is YES, that is, the cooling operation has been performed during the predetermined period, the determination unit (42) proceeds to step ST807. If the determination result is NO, that is, the cooling operation has not been performed during the predetermined period, the determination unit (42) proceeds to step ST806. The cooling operation here refers to the case where only a cooling operation has been performed without a dehumidifying operation.

[0156] In step ST806, the determining section 42 determines that release is not necessary, and the control section 40 stops release of the inhibitor from the release section 20.

[0157] In step ST807, the determination unit 42 determines that the amount of emission should be set to the fourth amount of emission. The control unit 40 controls the emission unit 20 so that the amount of the inhibitor emitted into the target space S becomes the fourth amount of emission. After step ST807, the process returns.

[0158] In step ST808, the determination unit (42) determines that the amount of emission should be the fifth amount of emission. The control unit (40) controls the emission unit (20) so that the amount of the inhibitor emitted into the target space (S) becomes the fifth amount of emission. After step ST808, the process returns.

[0159] In step ST809, the determination unit 42 determines that the amount of emission should be set to the sixth amount of emission. The control unit 40 controls the emission unit 20 so that the amount of the inhibitor emitted into the target space S becomes the sixth amount of emission. After step ST809, the process returns.

[0160] (7) Effects of the Second Embodiment The inhibitor release system (500) of the second embodiment controls the amount of inhibitor released into the target space (S), which inhibits the activity of insects (I), based on operation information of the indoor unit (31) in the target space (S). The temperature of the target space (S) can be estimated from the temperature setting of the indoor unit (31). Furthermore, if a dehumidifying operation is being performed, it can be estimated that the indoor humidity is relatively high. Therefore, the operation information of the indoor unit (31) can serve as information indicating the air condition of the target space (S). In particular, by making a comprehensive judgment using the operation history for a predetermined period, the current air condition of the target space (S) can be accurately estimated. The inhibitor release system (500) adjusts the amount of inhibitor released based on the operation information of the indoor unit (31) without using a sensor, and therefore can enhance the inhibitory effect of the inhibitor with a simple configuration.

[0161] Other Embodiments The inhibitor emission system (100, 200, 300, 400, 500) may target insects (I) other than cockroaches and mites. The inhibitor emission system (100, 200, 300, 400, 500) may also target flies, stink bugs, etc. For example, flies tend to breed in spaces with temperatures around 25°C, so the amount of inhibitor emitted is adjusted according to the temperature of the target space (S). Stink bugs prefer warm places, so the amount of inhibitor emitted is adjusted, for example, based on whether heating is used or not.

[0162] The inhibitor dissipation system (100, 200, 300, 400, 500) may treat the space inside the indoor unit (31) and the space inside the air purifier (430) as target spaces (S). The temperature and humidity of the air inside the indoor unit (31) and the temperature and humidity of the air inside the air purifier (430) can be detected using an indoor temperature sensor (61, 461) and an indoor humidity sensor (62, 462). The amount of inhibitor dissipation into the space inside the indoor unit (31) and the space inside the air purifier (430) can be controlled based on these temperatures and humidity.

[0163] The air conditioner may be any device other than the indoor unit (31) and the air purifier (430) as long as it is placed in the target space (S) and contributes to adjusting and controlling the temperature and air quality environment in the target space (S). For example, it may be a circulator or a far-infrared heater with a blowing function.

[0164] The indoor temperature sensor (61, 461) and the indoor humidity sensor (62, 462) do not have to be mounted in the indoor unit (31) and the air purifier (430). For example, the indoor temperature sensor (61, 461) and the indoor humidity sensor (62, 462) may be mounted in a terminal that remotely controls the indoor unit (31) and the air purifier (430). Furthermore, the device in which the dissipation unit (20, 420) is mounted may be different from the device in which the indoor temperature sensor (61, 461) and the indoor humidity sensor (62, 462) are mounted. For example, the dissipation unit (20) may be mounted in the indoor unit (31), and the indoor temperature sensor (461) and the indoor humidity sensor (462) may be mounted in the air purifier (430). In this case, the control unit (40) acquires information on the temperature and humidity of the target space (S) from the indoor temperature sensor (461) and the indoor humidity sensor (462) of the air purifier (430) through communication.

[0165] The amount of inhibitor emitted may be calculated using a formula that uses the temperature and humidity of the target space (S) as variables. Alternatively, the amount of inhibitor emitted may be set using a control map that sets the amount of inhibitor emitted depending on the temperature and humidity of the target space (S).

[0166] The amount of inhibitor to be sprayed may be estimated by a trained model that has been trained using, as training data, the air conditions in the target space (S) and information on the amount of inhibitor emitted corresponding to the air conditions. Furthermore, as in Modifications 2 and 3, the type of target space (S) may be estimated by a trained model that has been trained using, as training data, operation information on the indoor unit (31) or the detection value of the human detection sensor (65) and the type of target space (S). The trained model may be stored in the control unit (40) or, as in Modification 3, in a server device (80).

[0167] When determining the amount of emission from the operation history of the air conditioner (30, 430), the operation time during a predetermined period may be taken into consideration. In this case, both the continuous operation time and the total operation time during the predetermined period may be taken into consideration.

Furthermore, the above embodiments, modifications, and other embodiments may be combined or substituted as appropriate as long as the functionality of the subject matter of the present disclosure is not impaired.
