Description

[Technical Field]

[0001] FIELD OF THE DISCLOSURE The present disclosure relates to insect control systems and air treatment devices. [Background technology]

[0002] It has long been known that insects release various pheromones into the air. The pheromones released by insects affect the behavior of other insects of the same species. In recent years, advances in the analysis of insect olfactory reception have led to the development of technology for detecting insect pheromones by artificially reproducing the insect's olfactory function. The odor sensor described in Patent Document 1 is equipped with a cell chip in which insect olfactory receptor proteins have been reconstructed through genetic engineering. This cell chip detects the pheromones of the target insect. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-27376 Summary of the Invention [Problem to be solved by the invention]

[0004] By placing a sensor that detects gases such as pheromones emitted by insects in a target space, such as the living room or kitchen of a house, it is possible to detect insects present in the target space. However, if the target space has a complex structure or the amount of gas emitted by the insects is small, it may not be possible to detect the insects present in the target space. Furthermore, even if the insects are detected, a person must capture or remove them, which can cause discomfort or fear.

[0027] 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.

[0028] First Embodiment (1) Insect control system The insect control system (100) of the present disclosure is a system for exterminating insects (I) present in a target space (S). The insect control system (100) of the present disclosure can create an environment in the target space (S) with a reduced number of insects (I) 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, "extermination" includes using a repellent effect that insects (I) instinctively dislike, and using an inhibitory effect that inhibits the activity of the insects' (I) olfactory receptors, thereby reducing the sensitivity of their olfactory function.

[0029] As shown in Figure 1, the target space (S) is an indoor space where people stay, such as an office, a bedroom, living room, or kitchen in a house. The target insect species to be exterminated by the insect extermination system (100) include, for example, mosquitoes, moths, flies, cockroaches, spiders, and mites. These target insect species (I) are pests that occur relatively frequently in the target space (S) where people live.

[0030] The insect control system (100) of the first embodiment includes a gas sensor (10), a dissipation unit (21), an air conditioner (30) that is an air treatment device, a control unit (40), and a communication terminal (50).

[0031] The air conditioner (30) adjusts the temperature and humidity of air in a target space (S). The indoor unit (31) of the air conditioner (30) is a wall-mounted type. Specifically, the indoor unit (31) is installed on the upper part of an interior wall of a building.

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

[0033] (1-1) Gas sensor The gas sensor (10) detects gas emitted by an insect (I) of a target insect species. The gas sensor (10) outputs the strength or concentration of the gas emitted by the insect (I) as a detected value. In this embodiment, two gas sensors (10) are provided in the target space (S).

[0034] The first gas sensor (11) is provided in the gas sensor unit (13). The gas sensor unit (13) includes a sensor case (14), the first gas sensor (11), and a first communication unit (15). The sensor case (14) is configured in a hollow box shape. The first gas sensor (11) and the first communication unit (15) are housed in the sensor case (14). The sensor case (14) is configured to be portable. The sensor case (14) corresponds to the casing of the present disclosure. The first gas sensor (11) is placed on, for example, the floor surface of the target space (S). The first communication unit (15) includes a transmitter that transmits a detection value of the first gas sensor (11) to the control unit (40).

[0035] The second gas sensor (12) is housed in the indoor unit (31). The second gas sensor (12) is attached, for example, near the inlet (32a) in the indoor unit (31).

[0036] By disposing a plurality of gas sensors (10) in the target space (S), gas emitted by insects (I) can be reliably detected. However, only one gas sensor (10) may be disposed in the target space (S). Furthermore, the first gas sensor (11) is housed in a portable casing (14). This allows the gas sensor (10) to be disposed in a location in the target space (S) where insects (I) are likely to be found (for example, a dark place such as a corner of the target space (S) or under furniture), thereby enabling more reliable detection of gas emitted by insects (I).

[0037] Here, the gas detected by the gas sensor (10) in this embodiment is a specific gas emitted by the insect (I). Specifically, the gas sensor (10) detects the pheromones of the insect (I). Pheromones are specific gases emitted by the insect (I), and are organic compounds that are produced inside the insect (I) and released outside the body to induce specific behaviors or physiological effects among individuals of the same species. Most pheromones are perceived as olfactory stimuli. Pheromones include alarm pheromones that alert other individuals of the same species to danger, and sex pheromones that attract members of the opposite sex of the same species. The gas detected by the gas sensor (10) may be a specific gas other than a pheromone.

[0038] A known sensor capable of detecting gases emitted by the insects I is used as the gas sensor 10. For example, a wet sensor such as a cell chip generated from pheromone receptor cells of the insect I, or a dry sensor configured by combining multiple electronic sensors may be used as the gas sensor 10.

[0039] (1-2) Dissipation section The diffusing section (21) diffuses the pesticide into the target space (S). The diffusing section (21) constitutes the extermination section (20) that performs an extermination operation capable of exterminating the insects (I). The diffusing section (21) is housed in the indoor unit (31). The diffusing section (21) is disposed, for example, near the air outlet (32b) of the indoor unit (31).

[0040] The diffusing unit (21) of this embodiment is a spray device that emits a liquid pesticide in the form of a mist. The diffusing unit (21) performs a diffusing operation as an extermination operation. The diffusing unit (21) of this 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 tank stores the liquid pesticide. 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 pesticide. One tank or multiple tanks may be provided. The diffusing unit (21) may have multiple tanks that store different types of pesticides.

[0041] 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 pesticide emitted from the emitting section (21) is adjusted. The amount of pesticide emitted may be adjusted by means other than adjusting the opening rate of the flow rate control valve. For example, the amount of pesticide emitted may be adjusted by intermittently operating the air pump.

[0042] The pesticide used in this embodiment is a repellent having a repellent effect that insects (I) instinctively dislike, or an inhibitor having an inhibitory effect that inhibits the activity of the olfactory receptors of insects (I) and reduces the sensitivity of the olfactory function. By using a pesticide having a repellent or inhibitory effect, the impact on human health can be reduced.

[0043] (1-3) 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).

[0044] The air conditioner (30) has an indoor unit (31) installed in the target space (S) and an outdoor unit (not shown) installed outdoors. The indoor unit (31) is connected to the outdoor unit by a refrigerant pipe. 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).

[0045] As shown in Fig. 1, the indoor unit (31) includes a housing (32), an indoor heat exchanger (33), an indoor fan (34), and a flap (35). In Fig. 1, the indoor unit (31) is shown in cross section to explain the general configuration of the indoor unit (31).

[0046] The housing (32) is formed in the shape of a horizontally elongated hollow box. The housing (32) has a substantially rectangular cross section. An inlet (32a) is formed in each of the front and top surfaces of the housing (32). An outlet (32b) is formed in the front lower portion of the housing (32). In this embodiment, the second gas sensor (12) is disposed near the inlet (32a) formed in the top portion of the housing (32).

[0047] The indoor heat exchanger (33) is housed in the housing (32). The indoor heat exchanger (33) functions as a condenser (in heating operation) or an evaporator (in cooling operation) in the refrigerant circuit.

[0048] The indoor fan (34) corresponds to the airflow generating unit of the present disclosure. The indoor fan (34) is housed in the housing (32). The indoor fan (34) is a cross-flow fan. The indoor fan (34) transports air in the target space (S) to the detection area of ​​the gas sensor (10). 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). Here, the detection area of ​​the gas sensor (10) refers to the range in which the gas sensor (10) can detect gas emitted by the insect (I). The detection area of ​​the gas sensor (10) is the space surrounding the gas sensor (10).

[0049] When the indoor fan (34) is operated, 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). By forming a flow circulating through the target space (S) in this way, gas emitted by insects (I) is carried along this air flow. This ensures that the gas is transported to the detection area of ​​the gas sensor (10) regardless of the location of the gas.

[0050] The indoor fan (34) diffuses the air mixed with the pesticide released from the diffusing section (21) into the target space (S). The pesticide is mixed in a mist form with the airflow generated by the indoor fan (34), and this airflow circulates through the target space (S), thereby distributing the pesticide throughout the entire target space (S).

[0051] 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 delivered toward, for example, the floor, wall, or ceiling surface facing the target space (S), or toward specific furniture.

[0052] (1-4) Control unit The control unit (40) shown in Fig. 2 controls the diffusor (21), the indoor fan (34), and the flap (35). The control unit (40) includes a microcomputer mounted on a control board and a memory device (specifically, a semiconductor memory) that stores software for operating the microcomputer. The control unit (40) may also function as a control device for the air conditioner (30) or a control device for the communication terminal (50).

[0053] The control unit (40) adjusts the amount of pesticide diffused from the diffuser (21) based on the detection value of the gas sensor (10). In this embodiment, the control unit (40) adjusts the amount of pesticide diffused by controlling the flow rate regulating valve of the diffuser (21) based on the detection value of the gas sensor (10).

[0054] The control unit (40) has a second communication unit (41) and a determination unit (42) as functional units. The second communication unit (41) is connected to the gas sensor unit (13) and the communication terminal (50) via a wired or wireless communication line. The second communication unit (41) is connected to other devices by wireless communication via, for example, a wireless router. The second communication unit (41) includes a receiving unit that receives the detection values ​​transmitted from the gas sensors (10). The second communication unit (41) includes a transmitting unit that transmits information about insects to the communication terminal (50).

[0055] The determination unit (42) determines the level of insect abundance in the target space (S) from the detection values ​​of the gas sensors (10) received by the second communication unit (41). The level of insect abundance is determined, for example, on a five-level scale. In detail, for example, level 0 indicates no insects, level 1 indicates a few insects, level 2 indicates a moderate number of insects, level 3 indicates a large number of insects, and level 4 indicates a very large number of insects. When the detection value of the gas sensor (10) is 0 (zero), the determination unit (42) determines the level as 0. The larger the detection value of the gas sensor (10), the higher the determination level.

[0056] (1-5) Communication terminal The communication terminal (50) is a terminal operated by a person. In this embodiment, the communication terminal (50) is a smartphone. 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 third communication unit (53) as functional units.

[0057] The operation unit 51 of this embodiment is configured as a touch panel of the communication terminal 50. A person can use the operation unit 51 to operate application software stored in the communication terminal 50, thereby activating or deactivating the insect control system 100 and displaying information about insects on the notification unit 52.

[0058] The notification unit (52) notifies information about insects present in the target space (S). In this embodiment, the notification unit (52) is configured as a liquid crystal panel of the communication terminal (50). The information about insects displayed on the notification unit (52) includes the presence or absence of insects (I) in the target space (S), the level of insect abundance in the target space (S), and the likelihood of insect infestation in the target space (S). The notification unit (52) may display the detection of an insect (I) when the gas sensor (10) detects gas emitted by the insect (I), or may display information about the insect when the operation unit (51) sends a command to the control unit (40) to display information about the insects. In this way, providing people with information about the insects (I) present in the target space (S) can give them a sense of security.

[0059] The third communication unit (53) includes a transmitting unit that transmits commands input through the operation unit (51) to the control unit (40). The third communication unit (53) includes a receiving unit that receives information about insects transmitted from the control unit (40).

[0060] (2) Operation of the insect control system The following describes the operation of the insect extermination system 100. The operation of the insect extermination system 100 includes an extermination operation mode.

[0061] In the extermination operation mode, when the insect extermination 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 operation of the insect extermination system (100) stops.

[0062] After turning on the indoor fan (34), as shown in FIG. 3 , the control unit (40) determines in step ST1 whether or not insects (I) are present in the target space (S). Specifically, the detection values ​​of the first gas sensor (11) and the second gas sensor (12) are transmitted to the control unit (40). The determination unit (42) of the control unit (40) determines the level of insect infestation in the target space (S), for example, based on the sum of the transmitted detection values ​​of the first gas sensor (11) and the second gas sensor (12). When the first gas sensor (11) or the second gas sensor (12) detects gas emitted by insects (I), the determination unit (42) determines that the level is 1 or higher. When the determination unit (42) determines that level is 1 or higher, it is determined that insects (I) are present in the target space (S), and step ST2 is executed (YES in step ST1).

[0063] In step ST2, the control unit (40) causes the diffusing unit (21) to start the diffusing operation. Specifically, the control unit (40) controls the diffusing unit (21) to diffuse the pesticide into the target space (S) in an amount corresponding to the level determined by the determination unit (42).

[0064] In step ST3, if a predetermined time has elapsed, the control unit (40) executes step ST4. In step ST4, the control unit (40) determines whether the number of insects in the target space (S) has decreased. Specifically, for example, the determination unit (42) of the control unit (40) determines the level of insect abundance based on the sum of the detection values ​​of the first gas sensor (11) and the second gas sensor (12). If the determined level has decreased, it is determined that the number of insects (I) in the target space (S) has decreased. If the number of insects in the target space (S) has decreased, step ST5 is executed (YES in step ST4).

[0065] In step ST5, the control unit (40) reduces the amount of pesticide to be diffused. Specifically, the control unit (40) reduces the opening of the flow rate control valve of the diffusion unit (21) and then causes the diffusion unit (21) to perform the diffusion operation.

[0066] In step ST6, the control unit (40) determines whether or not there are no insects in the target space (S). Specifically, the control unit (40) determines whether or not the detection values ​​of the first gas sensor (11) and the second gas sensor (12) have both become 0 (zero). If it is determined that there are no insects in the target space (S) (YES in step ST6), the control unit (40) stops the emitting operation of the emitting unit (21) in step ST7.

[0067] If the number of insects in the target space (S) has not decreased in step ST4, the control unit (40) executes step ST8 (NO in step ST4).

[0068] In step ST8, the control unit (40) determines whether the number of insects in the target space (S) has increased. Specifically, for example, the determination unit (42) of the control unit (40) determines the level of insect infestation based on the sum of the detection values ​​of the first gas sensor (11) and the second gas sensor (12). If the determined level has increased, it is determined that the number of insects (I) in the target space (S) has increased. If the number of insects in the target space (S) has increased, step ST is executed (YES in step ST8).

[0069] In step ST9, the control unit (40) increases the amount of pesticide to be diffused. Specifically, the control unit (40) increases the opening of the flow rate adjustment valve of the diffusion unit (21) and then causes the diffusion unit (21) to perform the diffusion operation.

[0070] If the number of insects in the target space (S) has not increased in step ST8, the control unit (40) executes step ST10 (NO in step ST8). In step ST10, the control unit (40) maintains the amount of pesticide emitted from the emitting unit (21) without changing it.

[0071] In this manner, in the extermination operation mode, the control unit (40) adjusts the amount of pesticide emitted from the emitting unit (21) based on the detection value of the gas sensor (10). As a result, when the detection value of the gas sensor (10) is small, the amount of pesticide emitted can be reduced, thereby preventing excessive consumption of the pesticide. When the detection value of the gas sensor (10) is large, a necessary and sufficient amount of pesticide for exterminating many insects can be emitted. As a result, an appropriate amount of pesticide can be emitted into the target space (S).

[0072] (3) Features of the First Embodiment (3-1) The insect extermination system (100) of this embodiment includes a gas sensor (10) that detects gas emitted by insects (I) of a target insect species, an airflow generating unit (34) that transports air in the target space (S) to the detection area of ​​the gas sensor (10), an extermination unit (20) that performs an extermination operation capable of exterminating the insects (I) or other insects (I) of the target insect species present in the target space (S), and a control unit (40) that controls the extermination unit (20) based on the detection value of the gas sensor (10).

[0073] Because the airflow generating unit (34) transports air in the target space (S) to the detection area of ​​the gas sensor (10), if an insect (I) of a target insect species is present in the target space (S), the gas emitted by the insect (I) can be reliably transported to the detection area of ​​the gas sensor (10) regardless of the structure of the target space (S), even if the target space (S) has a complex layout or a large area. This improves the detection accuracy of insects present in the target space (S). The control unit (40) controls the extermination unit (20) based on the detection value of the gas sensor (10) with improved detection accuracy, thereby reliably exterminating gas-emitting insects (I) present in the target space (S) or insects of the same species as the insects (I). This reduces the number of insects in the target space (S).

[0074] (3-2) The extermination unit (20) includes a diffusing unit (21) that diffuses into the target space (S) a pesticide that has an insect-killing effect. The control unit (40) adjusts the amount of pesticide diffused from the diffusing unit (21) based on the detection value of the gas sensor (10). Therefore, for example, when the detection value of the gas sensor (10) is small, the amount of pesticide diffused can be reduced. When the detection value of the gas sensor (10) is large, a necessary and sufficient amount of pesticide can be diffused to exterminate insects in the target space (S). This allows an appropriate amount of pesticide to be diffused into the target space (S).

[0075] (3-3) The insect extermination system (100) includes a notification unit (52) that notifies information about insects present in the target space (S) based on the detection value of the gas sensor (10). This allows information about insects present in the target space (S) to be provided to people, thereby providing a sense of security to people.

[0076] (3-4) The first gas sensor (11) is housed in a portable casing (14). This allows the casing (14) to be placed in a location in the target space (S) where insects (I) are likely to be found, thereby more reliably detecting gas emitted by the insects (I) present in the target space (S). This allows the gas sensor (10) housed in the casing (14) to perform its function more effectively in the target space (S).

[0077] (4) Modification of the first embodiment The above embodiment may be modified as follows: In the following description, differences from the above embodiment will be mainly explained.

[0078] (4-1) Modification 1: Control based on human detection sensors As shown in Fig. 4, the insect control system (100) may include a human detection sensor (61). The human detection sensor (61) detects the presence of a human in the target space (S). The human detection sensor (61) may detect the number of people or the number of people. The human detection sensor (61) is attached, for example, near the air outlet (32b) of the indoor unit (31).

[0079] The control unit (40) adjusts the amount of pesticide to be diffused from the diffuser (21) based on the detection value of the human detection sensor (61). Specifically, in this modification, in the extermination operation mode of the insect extermination system (100), the control unit (40) performs first control, second control, or third control. The first to third controls will be described below.

[0080] (4-1-A) First Control In the first control, steps ST1, ST4, ST6, and ST8 are different from the operation of the insect control system (100) of the first embodiment.

[0081] Specifically, in step ST1 of the first control, the control unit (40) determines whether or not a condition for starting the dispersal operation is met. The condition for starting the dispersal operation in the first control is that insects (I) are present in the target space (S) and that a person is present in the target space (S). The determination of whether or not insects (I) are present in the target space (S) is made in the same manner as in the first embodiment. The determination of whether or not a person is present in the target space (S) is made by the control unit (40) from the detection value of the person detection sensor (61).

[0082] In step ST4 of the first control, the control unit (40) determines whether the number of people in the target space (S) has decreased. Specifically, when the detection value of the human detection sensor (61) decreases, the control unit (40) determines that the number of people in the target space (S) has decreased. When the number of people in the target space (S) has decreased, step ST5 is executed (YES in step ST4).

[0083] In step ST6 of the first control, the control unit (40) determines whether or not a condition for stopping the dispersal operation is met. The condition for stopping the dispersal operation in the first control is that there are no insects (I) in the target space (S) or that there is no person in the target space (S). The determination of whether or not there are no insects (I) in the target space (S) is made in the same manner as in the first embodiment. The determination of whether or not there is no person in the target space (S) is made by the control unit (40) based on whether or not the detection value of the person detection sensor (61) has become 0 (zero).

[0084] In this way, when there are no insects (I) or people in the target space (S), the pesticide is not emitted from the emitting part, so consumption of the pesticide can be reduced.

[0085] In step ST8 of the first control, the control unit (40) determines whether the number of people in the target space (S) has increased. Specifically, when the detection value of the human detection sensor (61) increases, the control unit (40) determines that the number of people in the target space (S) has increased. When the number of people in the target space (S) has increased, step ST9 is executed.

[0086] (4-1-B) Second Control In the second control, steps ST1 and ST6 are different from the operation of the insect control system (100) of the first embodiment.

[0087] In step ST1 of the second control, the control unit (40) determines whether or not the condition for starting the dispersal operation is met. The condition for starting the dispersal operation in the second control is that insects (I) are present in the target space (S) and that no people are present in the target space (S). The determination of whether or not insects (I) are present in the target space (S) is made in the same manner as in the first embodiment. The determination of whether or not no people are present in the target space (S) is made by the control unit (40) based on whether or not the detection value of the human detection sensor (61) has become 0 (zero).

[0088] In step ST6 of the second control, the control unit (40) determines whether or not a condition for stopping the dispersal operation is met. The condition for stopping the dispersal operation in the second control is that there are no insects (I) in the target space (S) or that there is a person in the target space (S). The determination of whether or not there are no insects (I) in the target space (S) is made in the same manner as in the first embodiment. The determination of whether or not there is a person in the target space (S) is made by the control unit (40) based on the detection value of the person detection sensor (61).

[0089] In this way, the pesticide is released from the release unit when there is no one in the target space (S), which prevents insects (I) from settling in the target space (S) while there is no one there. In addition, the pesticide is not released when there is a person in the target space (S), which reduces the impact on human health.

[0090] (4-1-C) Third Control In the third control, step ST2 is different from the operation of the insect control system (100) of the first embodiment.

[0091] In step ST2 of the third control, the control unit (40) causes the emitting unit (21) to start the emitting operation. At this time, the control unit (40) determines whether or not a person is present in the target space (S) based on the detection value of the human detection sensor (61). If it is determined that a person is present, the control unit (40) sets the amount of pesticide to be emitted from the emitting unit (21) to an amount that is, for example, reduced by a predetermined amount from the amount corresponding to the level of insect infestation determined by the determination unit (42). In this way, by reducing the amount of pesticide to be emitted when a person is present in the target space (S), it is possible to reduce the impact on human health.

[0092] (4-2) Modification 2: Control based on ventilation information In the insect control system (100), the control unit (40) may control the diffusing unit (21) based on ventilation information related to the ventilation rate of the target space (S), because the ventilation rate of the target space (S) affects the concentration of the pesticide in the target space (S).

[0093] (4-2-1) 5, the insect control system of this modification includes a first concentration sensor (62) that measures the carbon dioxide concentration in the target space (S) and a human detection sensor (61) that detects the presence of a human in the target space (S). The first concentration sensor (62) and the human detection sensor (61) are attached to, for example, the air conditioner (30).

[0094] The control unit (40) estimates ventilation information based on the detection value of the first concentration sensor (62) and the detection value of the human detection sensor (61), and adjusts the amount of pesticide to be diffused from the diffuser (21) based on the estimated ventilation information. In this modification, in the extermination operation mode of the insect control system (100), the control unit (40) performs the fourth control or the fifth control. The fourth control and the fifth control are performed according to their respective purposes. The fourth control and the fifth control will be described below.

[0095] (4-2-1A) 4th control 6, in the fourth control, the indoor fan (34) is turned on, and then the control unit (40) executes steps ST101 to ST103, similarly to the operation in the first embodiment. Steps ST101 to ST103 in the fourth control are the same as steps ST1 to ST3 in the first embodiment.

[0096] In step ST103, if a predetermined time has elapsed, the control unit (40) executes step ST104. In step ST104, the control unit (40) determines whether or not a person is present in the target space (S). Specifically, the control unit (40) makes this determination based on the detection value of the human detection sensor (61). If it is determined in step ST104 that a person is present, step ST105 is executed (YES in step ST104). If it is determined that no person is present, step ST107 is executed (NO in step ST104).

[0097] In step ST105, the control unit (40) determines whether the carbon dioxide concentration C in the target space (S) is equal to or greater than a reference concentration C1. The carbon dioxide concentration C in the target space (S) is obtained from the first concentration sensor (62). The control unit (40) makes the determination by comparing the detected value of the first concentration sensor (62) with the reference concentration C1. The reference concentration C1 is, for example, 800 ppm.

[0098] In step ST105, if it is determined that the concentration C is equal to or greater than the reference concentration C1, step ST106 is executed (YES in step ST105).If it is determined that the concentration C is less than the reference concentration C1, step ST107 is executed (NO in step ST105).

[0099] Here, if it is determined in step ST105 that the concentration C is equal to or greater than the reference concentration C1, then people are present in the target space (S) and the carbon dioxide concentration is high, so it can be said that the target space (S) is not being ventilated or the ventilation rate is low. On the other hand, if it is determined in step ST105 that the concentration C is less than the reference concentration C1, then people are present in the target space (S) but the carbon dioxide concentration is low, so it can be said that the target space (S) is being ventilated or the ventilation rate is high.

[0100] In step ST106, the control unit (40) increases the amount of pesticide to be diffused. Specifically, the control unit (40) increases the opening of the flow rate adjustment valve of the diffusion unit (21), and then causes the diffusion unit (21) to perform the diffusion operation.

[0101] In step ST107, the control unit (40) reduces the amount of pesticide to be diffused. Specifically, the control unit (40) reduces the opening of the flow rate adjustment valve of the diffusion unit (21) and then causes the diffusion unit (21) to perform the diffusion operation.

[0102] In this way, the control unit (40) increases the amount of pesticide emitted when the target space (S) is not ventilated or the amount of ventilation is low. On the other hand, the control unit (40) decreases the amount of pesticide emitted when the target space (S) is ventilated or the amount of ventilation is high. When the amount of ventilation is high in the target space (S), the diffused pesticide is released outside, resulting in wasteful consumption of the pesticide. In this modification, the amount of pesticide emitted decreases when the amount of ventilation in the target space (S) is high, thereby preventing wasteful consumption of the pesticide.

[0103] Steps ST108 and ST109 in the fourth control are the same as steps ST6 to ST7 in the first embodiment.

[0104] (4-2-1B) 5th Control The fifth control differs from the fourth control in step ST105. Specifically, in step ST105, the control section (40) determines whether the concentration C of carbon dioxide in the target space (S) is lower than the reference concentration C1.

[0105] In step ST105, if it is determined that the concentration C is smaller than the reference concentration C1, step ST106 is executed (YES in step ST105).If it is determined that the concentration C is equal to or larger than the reference concentration C1, step ST107 is executed (NO in step ST105).

[0106] In this way, the control unit (40) increases the amount of pesticide emitted when the target space (S) is ventilated or the ventilation rate is high. On the other hand, the control unit (40) decreases the amount of pesticide emitted when the target space (S) is not ventilated or the ventilation rate is low. When the ventilation rate is high in the target space (S), the diffused pesticide is released outside. In this modification, the amount of pesticide emitted is increased when the ventilation rate in the target space (S) is high, thereby compensating for the pesticide that would otherwise be released outside and maintaining the concentration of pesticide in the target space (S) at a concentration appropriate for exterminating insects (I).

[0107] (4-2-2) The human detection sensor (61) may detect the number of people or the number of people. The control unit (40) acquires number-of-people information on the number of people present in the target space (S) from the detection value of the human detection sensor (61). Note that the "number-of-people information" here includes information that there are no people in the target space.

[0108] The control unit (40) estimates ventilation information based on the detection value of the first concentration sensor (62) and the information on the number of people present, and adjusts the amount of pesticide to be diffused from the diffusing unit (21) based on the estimated ventilation information.

[0109] For example, when the control unit (40) acquires number of people information indicating that there are many people in the target space (S) even though the detection value of the first concentration sensor (62) is small and the carbon dioxide concentration in the target space (S) is low, it outputs ventilation information indicating that the ventilation rate in the target space (S) is high.

[0110] (4-2-3) Acquisition of ventilation information is not limited to the means using the first concentration sensor 62 and the human detection sensor 61. For example, if the insect control system 100 includes a ventilation device as an air treatment device, ventilation information may be acquired from the ventilation volume of the ventilation device.

[0111] (4-3) Variation 3: Control based on pesticide concentration 7, the insect control system 100 may have a second concentration sensor 63 for measuring the concentration of the pesticide in the target space S. The second concentration sensor 63 is attached to, for example, the gas sensor unit 13.

[0112] The control unit (40) adjusts the amount of pesticide diffused from the diffuser (21) based on the detection value of the second concentration sensor (63). Specifically, the control unit (40) controls the amount of diffused pesticide based on the detection value of the second concentration sensor (63) so that the concentration of the pesticide in the target space (S) is maintained at a set target value. Here, the set target value is a concentration of the pesticide that can exterminate the insects (I) present in the target space (S), and may be set to a different value depending on the detection value of the gas sensor (10).

[0113] Specifically, when the detection value of the second concentration sensor (63) is smaller than the target value, the control unit (40) increases the degree of opening of the flow rate adjustment valve so as to increase the amount of pesticide emitted from the diffusion unit (21). On the other hand, when the detection value of the second concentration sensor (63) is larger than the target value, the control unit (40) decreases the degree of opening of the flow rate adjustment valve so as to decrease the amount of pesticide emitted from the diffusion unit (21).

[0114] In this way, the amount of the pesticide to be released is adjusted in accordance with the value detected by the second concentration sensor (63), so that the concentration of the pesticide in the target space (S) can be maintained at a concentration appropriate for exterminating insects.

[0115] (4-4) Variation 4: Control based on insect species The gas sensor 10 of the insect control system 100 may detect the type of insect. In this case, the control unit 40 obtains information about the type of insect present in the target space S based on the detection value of the gas sensor 10.

[0116] The control unit (40) may change the type of pesticide to be emitted from the emission unit (21) in accordance with the acquired information on the type of insect. This allows an appropriate pesticide to be emitted in accordance with the type of insect (I) that has appeared in the target space (S). As a result, the insects (I) present in the target space (S) can be more reliably exterminated.

[0117] (4-5) Variation 5: Dissipation section The diffusing unit (21) of the insect control system (100) may be an electrostatic spraying device. In an electrostatic spraying device, an electrically charged liquid (repellent) is sprayed from the tip of a spray nozzle. By releasing the electrically charged pesticide into the target space (S), the pesticide easily adheres to the floor, wall, or ceiling surfaces facing the target space (S).

[0118] The dispersing unit 21 of the insect control system 100 may also be an ultrasonic or piezoelectric spray device. In an ultrasonic spray device, the liquid is atomized by vibration energy generated by an ultrasonic vibrator. In a piezoelectric spray device, the liquid is atomized by repeated deformation and restoration of a piezoelectric element. These spray devices allow the dispersing unit 21 to be constructed inexpensively and reduce the noise associated with driving the dispersing unit 21. Additionally, these spray devices allow for stable supply of minute amounts of liquid.

[0119] Second Embodiment The insect extermination system (100) of the second embodiment is the insect extermination system (100) of the first embodiment, except that the extermination unit (20) is changed. Here, the differences between the extermination unit (20) of the second embodiment and the extermination unit (20) of the first embodiment will be described.

[0120] As shown in FIG. 8, the insect extermination system (100) of this embodiment has a temperature adjustment unit (22) as the extermination unit (20). The temperature adjustment unit (22) adjusts the temperature of the target space (S). The temperature adjustment unit (22) of this embodiment is configured by the temperature adjustment function of the air conditioner (30). The control unit (40) controls the temperature adjustment unit (22) based on the detection value of the gas sensor (10).

[0121] The operation of the insect control system (100) of this embodiment will be described. In the extermination operation mode of the insect control system (100), as in the first embodiment, when the insect control system (100) starts operation, 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 operation of the insect control system (100) is stopped.

[0122] After turning on the indoor fan (34), the control unit (40) determines whether or not there is an insect (I) in the target space (S) in step ST201, as shown in Fig. 9. The determination in step ST201 is performed in the same manner as in step ST1 in the first embodiment. If it is determined in step ST201 that there is an insect (I) in the target space (S), step ST202 is executed (YES in step ST201).

[0123] In step ST202, the control unit (40) causes the temperature adjustment unit (22) to start a temperature adjustment operation. In the temperature adjustment operation, the control unit (40) controls the temperature adjustment unit (22) so that the target space (S) is at a temperature that is inhospitable to insects (I). Specifically, in the temperature adjustment operation, a cooling operation is performed in which the outdoor heat exchanger of the outdoor unit functions as a radiator and the indoor heat exchanger (33) functions as an evaporator. The cooling operation cools the air passing through the indoor heat exchanger (33). This reduces the temperature of the target space (S) to a target temperature. The temperature of the target space (S) is reduced because insects (I) dislike low-temperature environments.

[0124] The "target temperature" here is a temperature at which insects (I) have difficulty settling, and may vary depending on the type of insects (I) present in the target space (S). Furthermore, the "target temperature" may be set to a temperature that does not impair comfort when people are present in the target space (S).

[0125] In step ST203, if a predetermined time has elapsed, the control unit (40) executes step ST204. In step ST204, the control unit (40) determines whether or not there are no insects in the target space (S). The determination in step ST204 is made in the same manner as in step ST6 of the first embodiment. If it is determined that there are no more insects (I) in the target space (S) (YES in step ST204), the control unit (40) stops the temperature adjustment operation in step ST205.

[0126] In this way, the control unit (40) controls the temperature adjustment unit (22) to lower the temperature of the target space (S), thereby creating an environment that is difficult for insects (I) to live in, and driving away insects (I) present in the target space (S) from the target space (S). As a result, the number of insects (I) present in the target space (S) can be reduced.

[0127] In this embodiment, the insect control system (100) reduces the number of insects (I) present in the target space (S) solely through the temperature adjustment operation of the temperature adjustment unit (22) without using any pesticide, thereby further reducing the impact on human health. Note that in this embodiment, the control unit (40) may change the performance of the temperature adjustment unit (22) based on the detection value of the gas sensor (10).

[0128] Third Embodiment The insect extermination system (100) of the third embodiment is the insect extermination system (100) of the second embodiment, except that the extermination unit (20) is changed. Here, the differences between the extermination unit (20) of the present embodiment and the extermination unit (20) of the second embodiment will be described.

[0129] As shown in FIG. 10, the insect extermination system (100) of this embodiment includes a humidity adjustment unit (23) as the extermination unit (20). The humidity adjustment unit (23) adjusts the humidity of the target space (S). The humidity adjustment unit (23) of this embodiment is configured by the humidity adjustment function of the air conditioner (30). The control unit (40) controls the humidity adjustment unit (23) based on the detection value of the gas sensor (10).

[0130] The following describes the operation of the insect extermination system 100 of this embodiment. The extermination operation mode of the insect extermination system 100 of this embodiment differs from the operation of the second embodiment in step ST202.

[0131] In step ST202, the control unit (40) causes the humidity adjustment unit (23) to start a humidity adjustment operation. In the humidity adjustment operation, the control unit (40) controls the humidity adjustment unit (23) so that the humidity in the target space (S) becomes unsuitable for insects (I). Specifically, in the humidity adjustment operation, a dehumidification operation is performed in which the outdoor heat exchanger of the outdoor unit functions as a radiator and the indoor heat exchanger (33) functions as an evaporator. In the dehumidification operation, the air that has passed through the indoor heat exchanger (33) is cooled to a temperature equal to or lower than the dew point temperature. This causes moisture in the air to condense, and the air is dehumidified. This reduces the humidity in the target space (S). The humidity in the target space (S) is reduced because insects (I) dislike low-humidity environments.

[0132] The "target humidity" here is a humidity at which insects (I) have difficulty settling, and may vary depending on the type of insects (I) present in the target space (S). Also, when there are people in the target space (S), the "target humidity" may be set to a humidity that does not impair comfort.

[0133] In this way, the control unit (40) controls the humidity adjustment unit (23) to reduce the humidity in the target space (S), thereby creating an environment that is inhospitable to insects (I) and driving the insects (I) present in the target space (S) out of the target space (S). As a result, the number of insects (I) present in the target space (S) can be reduced. In this embodiment, the control unit (40) may change the capacity of the humidity adjustment unit (23) based on the detection value of the gas sensor (10).

[0134] Fourth Embodiment The insect extermination system (100) of the fourth embodiment is the insect extermination system (100) of the second embodiment, except that the extermination unit (20) is changed. Here, the differences between the extermination unit (20) of the present embodiment and the extermination unit (20) of the second embodiment will be described.

[0135] As shown in FIG. 11, the insect extermination system (100) of this embodiment includes a sound generating unit (24) as the extermination unit (20). The sound generating unit (24) emits a sound into a target space (S) at a frequency that only insects (I) dislike. The frequency of the sound emitted by the sound generating unit (24) is, for example, 15 kHz to 20 kHz. The sound generating unit (24) is attached to, for example, an air conditioner (30). The control unit (40) controls the sound generating unit (24) based on the detection value of the gas sensor (10).

[0136] The extermination operation mode in the operation of the insect extermination system (100) of this embodiment differs from the operation of the second embodiment in step ST202.

[0137] In step ST202 of this embodiment, the control unit 40 controls the sound generation unit 24 to generate a sound of a frequency disliked by the insects I. By generating a sound of a frequency disliked only by the insects I in this manner, the insects I are repelled from the target space S, and the number of insects I is reduced.

[0138] The sound generated here is a sound of a frequency that humans cannot hear. Because the sound generated by the sound generating unit (24) is inaudible to humans, it is possible to repel insects (I) from the target space (S) without causing discomfort to people.

[0139] Other Modifications In each of the above embodiments, the following modified configurations may be adopted.

[0140] (1) Modification 1: Storage Unit 12, the control unit (40) may have a memory unit (43) as a functional unit. The control unit (40) may have the memory unit (43) separate from the control board.

[0141] The memory unit (43) has data including a plurality of types of insects (I) and the direction of airflow (wind direction) corresponding to each insect (I) (see FIG. 13). This data associates target insects with locations where the insects are likely to appear.

[0142] In the insect control system (100) of this modified example, the type of insect (I) to be exterminated may be preset according to the region (destination) where the insect control system (100) is to be installed when the insect control system (100) is shipped, or the type of insect (I) to be exterminated may be preset by an operator when installing the insect control system (100) in the target space (S). In this case, when the gas sensor (10) detects gas emitted by an insect (I), the control unit (40) controls the flap (35) of the indoor unit (31) based on the data stored in the memory unit (43) so that the airflow direction corresponds to the preset type of insect (I). The type of insect (I) is set by operating a dip switch, for example.

[0143] When the gas sensor (10) detects the type of insect present in the target space (S), the control unit (40) may obtain the wind direction corresponding to the type of insect (I) detected based on the data stored in the memory unit (43) during operation of the insect control system (100), and control the flap (35) of the indoor unit (31) to match the obtained wind direction.

[0144] (2) Modification 2: Stirring operation The control unit (40) may perform an agitation operation to agitate the air in the target space (S). The agitation operation corresponds to the first operation of the present disclosure. In the agitation operation, the control unit (40) periodically changes the position of the flap (35) over a short period of time. By agitating the air in the target space (S), gas emitted by the insect (I) that has been locally stagnating can be carried into the air flow circulating through the target space (S). This allows the gas emitted by the insect (I) to be transported to the gas sensor (10), allowing reliable detection of the gas from the insect (I).

[0145] In addition, when the insect control system (100) is equipped with a diffusion unit (21), the control unit (40) can perform a stirring operation to diffuse the pesticide diffused from the diffusion unit (21) throughout the target space (S).

[0146] The control unit (40) may execute the stirring operation at predetermined time intervals (for example, every hour) while the insect control system (100) is in operation.

[0147] As shown in FIG. 14, when the insect control system (100) includes a plurality of temperature sensors (64) for measuring the temperature of the target space (S), and the temperature sensors (64) are disposed at different positions in the target space (S), the control unit (40) may perform an agitation operation when there is a difference between the detected values ​​of the temperature sensors (64). If the detected values ​​of the temperature sensors (64) are different, it is highly likely that layers of air with different temperatures have formed in the target space (S). By performing the agitation operation in such a case, gas emitted by the insects (I) is transported to the gas sensor (10) along with the agitated air. This allows the gas sensor (10) to more reliably detect the gas emitted by the insects.

[0148] (3) Variation 3: Centralized operation The control unit (40) may perform at least one of the following concentrated operations: ceiling-concentrated operation, wall-concentrated operation, floor-concentrated operation, and fixture-concentrated operation. The ceiling-concentrated operation corresponds to the second operation of the present disclosure. The wall-concentrated operation corresponds to the third operation of the present disclosure. The floor-concentrated operation corresponds to the fourth operation of the present disclosure.

[0149] The ceiling-focused operation is an operation in which the flaps (35) direct air toward the ceiling surface facing the target space (S). The wall-focused operation is an operation in which the flaps (35) direct air toward the wall surface facing the target space (S). The floor-focused operation is an operation in which the flaps (35) direct air toward the floor surface facing the target space (S). The furniture-focused operation is an operation in which the flaps (35) direct air toward furniture such as sofas and bedding such as futons.

[0150] The control unit (40) executes any one of the concentrated operations, namely, ceiling concentrated operation, wall concentrated operation, floor concentrated operation, and fixture concentrated operation, so that gas from insects (I) that have appeared on the ceiling, wall, or floor of the target space (S) or around the fixtures can be transported in a concentrated manner to the gas sensor (10), thereby further reducing the number of insects present in the target space (S).

[0151] In addition, when the insect control system (100) is equipped with a diffusion unit (21), the control unit (40) can perform ceiling-focused operation, wall-focused operation, floor-focused operation, or fixture-focused operation, so that the pesticide diffused from the diffusion unit (21) can be diffused intensively in places where insects (I) are particularly likely to appear.

[0152] If the gas sensor (10) can detect the type of insect, the control unit (40) may determine the intensive operation to be performed based on information about the insect obtained from the detection value of the gas sensor (10). In this case, the control unit (40) may perform a combination of multiple intensive operations. This allows for more reliable detection of gas emitted by the insects (I) according to the type of insects (I) present in the target space (S), and for reliable extermination of the insects (I) by efficiently emitting a pesticide to the insects (I).

[0153] The control unit (40) is not limited to determining the concentrated operation to be performed based on the information about insects obtained from the detection value of the gas sensor (10), and may also control the flap (35) to direct air in an appropriate direction for exterminating the insects (I). Specifically, the control unit (40) may control the flap (35) to direct air to the boundary between the ceiling and wall surfaces, the boundary between two wall surfaces, the boundary between a wall surface and a floor surface, etc.

[0154] (4) Variation 4: Preventive Operation Mode The operation of the insect extermination system (100) may include a preventive operation mode in addition to an extermination operation mode. In the preventive operation mode, the control unit (40) performs an extermination operation when there are no insects (I) in the target space (S). Specifically, in the preventive operation mode, when the detection value of the gas sensor (10) is 0 (zero), the control unit (40) determines that there are no insects in the target space (S) and performs an extermination operation. This makes it possible to preventatively create an environment in the target space (S) that makes it difficult for insects (I) to invade, even if there are no insects in the target space (S). The preventive operation mode may be executed periodically at preset times, for example, or may be executed when there are no people in the target space (S).

[0155] (5) Variation 5: Control based on outdoor environment The control unit (40) may control the extermination unit (20) based on information about the environment of the outdoor space. The environment of the outdoor space affects the likelihood of insect (I) breeding. The information about the environment of the outdoor space here refers to the temperature, humidity, season, etc. of the outdoor space. The information about the environment of the outdoor space may be obtained, for example, from a temperature sensor and a humidity sensor disposed in the outdoor unit, or electronic information such as the current date, temperature, and humidity may be obtained via a communication line.

[0156] The control unit (40) has, as a functional unit, a prediction unit that predicts the likelihood of insect infestation based on information about the outdoor space environment. The prediction unit outputs the likelihood of insect infestation as an insect infestation risk in multiple levels. For example, the prediction unit outputs a high risk in summer, a medium risk in spring or autumn, and a low risk in winter.

[0157] In the extermination operation mode of the insect extermination system (100), the risk level output by the prediction unit is reflected in the extermination operation. Specifically, for example, when the extermination unit (20) is the emitting unit (21), if the output of the prediction unit indicates a high risk, the control unit (40) controls the emitting unit (21) to increase the amount of the exterminating agent to be emitted by a predetermined amount throughout the entire emission operation. On the other hand, if the output of the prediction unit indicates a low risk, the control unit (40) controls the emitting unit (21) to decrease the amount of the exterminating agent to be emitted by a predetermined amount throughout the entire emission operation.

[0158] In this way, the control unit (40) controls the extermination unit (20) based on information about the environment of the outdoor space, and therefore, when the environment of the outdoor space is one in which insects are likely to breed, the control unit (40) can control the extermination unit (20) to exterminate as many insects as possible. This can more reliably reduce the number of insects present in the target space (S). On the other hand, when the environment of the outdoor space is one in which insects are unlikely to breed, the control unit (40) can suppress the operation of the extermination unit (20).

[0159] When the prediction unit outputs a low risk signal, the control unit (40) may reduce the airflow rate of the indoor fan (34). This reduces the energy required to operate the insect control system (100) in an environment where insects (I) are unlikely to be generated, thereby saving energy.

[0160] The control based on the information about the outdoor space environment may be applied to a preventive operation mode. In this case, for example, if the output of the prediction unit indicates a high risk, the preventive operation mode may be executed, and if the output of the prediction unit indicates a low risk, the preventive operation mode may not be executed.

[0161] (6) Modification 6: Operation of the Airflow Generator The indoor fan (34) may be configured to change the speed of the air flowing into the target space (S). Specifically, for example, an intermittent airflow may be generated by periodically alternating low-speed and high-speed airflow over a short period of time. This allows gas emitted by insects that are locally resident in the target space (S) to be diffused throughout the target space (S). The diffused gas joins the flow circulating in the target space (S), thereby more reliably transporting the insect gas to the gas sensor (10).

[0162] (7) Modification 7: Information displayed on the notification unit The notification unit (52) may display the type of insect detected, the presence or absence of insects (I) while no one is present in the target space (S) or the level of insect abundance, a history of information about past insects, etc. Information about insects while no one is present in the target space (S) and information about past insects are stored, for example, in the memory unit (43) of the control unit (40). In this way, providing information about various insects (I) in the target space (S) can give people a sense of security.

[0163] (8) Modification 8: Arrangement of the extermination unit and airflow generation unit Although the insect extermination system (100) in each of the above embodiments includes one extermination unit (20), it may include multiple extermination units (20). When multiple extermination units (20) are included, the extermination units (20) may be housed in a portable casing. Because the extermination units (20) are portable, they can be placed in locations in the target space (S) where insects (I) are likely to be found. This allows for more effective extermination of the insects (I). When the extermination unit (20) is a dispersing unit (21), the portability of the dispersing unit (21) makes it easy to replace the tank that stores the extermination agent.

[0164] While the insect extermination system (100) in each of the above embodiments includes one airflow generating unit (34), it may include multiple airflow generating units (34). The multiple airflow generating units (34) may operate in conjunction with one another. Furthermore, when multiple airflow generating units (34) are included, the airflow generating units (34) may be housed in a portable casing. Because the airflow generating units (34) are portable, they can be placed in locations where air tends to stagnate, for example, to more efficiently circulate air in the target space (S). This allows gas emitted by the insects (I) to be more reliably transported to the gas sensor (10). In addition, the effect of the extermination unit (20) can be applied to the entire target space (S).

[0165] In this way, by making not only the gas sensor (10) but also the extermination unit (20) and the airflow generating unit (34) portable, each function can be more effectively performed. Note that the gas sensor (10), the extermination unit (20), and the airflow generating unit (34) do not necessarily need to be housed in separate casings; for example, the gas sensor (10) and the extermination unit (20) may be housed in a single casing.

[0166] (9) Variation 9: Indoor unit type The indoor unit (31) may be a ceiling-mounted type (a ceiling-embedded type or a ceiling-suspended type) or a floor-standing type. In the case of a ceiling-mounted indoor unit (31), the gas sensor (10) is disposed near an air inlet provided in the center of the indoor unit (31), as shown in Fig. 15. The diffusing part (21) is disposed near an air outlet provided to surround the air inlet.

[0167] (10) Variation 10: Combination of extermination parts The extermination unit (20) of the insect extermination system (100) may combine a dissipation unit (21), a temperature control unit (22), a humidity control unit (23), and a sound generation unit (24). By combining various types of extermination units (20), the insects (I) present in the target space (S) can be more effectively reduced.

[0168] (11) Variation 11: Air Treatment Device The air treatment device (30) may be any device other than an air conditioner (30) that can create a flow of air. The air treatment device (30) may be a humidity control device, a ventilation device, or an air purifier. The humidity control device adjusts the humidity of the air in the target space (S). The ventilation device ventilates the target space (S). The air purifier purifies the air in the target space (S).

[0169] Although the embodiments and modifications have been described above, it will be understood that various modifications in form and details are possible without departing from the spirit and scope of the claims. Furthermore, elements of the above embodiments, modifications, and other embodiments may be combined or substituted as appropriate.
