[0033] Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the drawings. In addition, in the embodiments described below, the same reference numerals are given to elements that are shared with each other, and repeated descriptions of the shared elements are sometimes omitted.

[0034] The following embodiments are merely one of various embodiments of the present disclosure. As long as the embodiments can achieve the object of the present disclosure, various changes can be made according to the design and the like. In addition, multiple embodiments (including modified examples) can also be appropriately combined to be implemented.

[0035] The diagrams described in the present disclosure are schematic diagrams, and the ratios of the sizes and thicknesses of the respective components in each diagram do not necessarily reflect the actual size ratios.

[0036] (Embodiment 1)

[0037] (1) Outline

[0038] First, with reference to Figures 1 to 3 the outline of the air conditioning system 2 according to Embodiment 1 will be described. Figure 1 It is a schematic diagram of a vehicle 1 including the air conditioning system 2 according to Embodiment 1. Figure 2 It is a schematic diagram showing the instrument panel 12 of the vehicle 1 in Embodiment 1. Figure 3 It is a schematic diagram showing the structure of the air conditioning system 2 according to Embodiment 1.

[0039] As Figure 1 and Figure 2As shown, the air conditioning system 2 is used for a vehicle 1 such as a car driven by a person. The air conditioning system 2 is provided in the equipment room 15 of the vehicle 1 and is used for operating a cooling device that conveys cold air into the passenger compartment 10 of the vehicle 1, operating a heating device that conveys warm air into the passenger compartment 10, and so on. The "vehicle" referred to in the present disclosure includes cars, large vehicles such as trucks or buses, trams, electric vehicles, construction machinery, and the like.

[0040] As Figure 3 shown, the air conditioning system 2 includes a blower 4, an evaporator 5, a housing 20, and a functional substance generating device 3.

[0041] The blower 4 generates a flow of air toward the inside of the passenger compartment 10 (refer to Figure 1 ).

[0042] The evaporator 5 is disposed in the middle of the air flow path and is used for heat exchange with the air passing through the evaporator 5. More specifically, heat exchange occurs between the air introduced into the air conditioning system 2 by the blower 4 and the evaporator. For example, in the case of the cooling device, the air introduced into the air conditioning system 2 is cooled during the heat exchange when passing through the evaporator and becomes cold air and is discharged outside the air conditioning system.

[0043] The housing 20 houses the blower 4 and the evaporator 5.

[0044] The functional substance generating device 3 generates a functional substance. The "functional substance" referred to in the present disclosure includes charged microparticle water, free radicals, air ions, and the like. In addition to having effects such as sterilization, deodorization, moisture retention, freshness preservation (i.e., maintaining freshness), or inactivation of viruses, the functional substance also has useful effects in various scenarios. In the following description, "sterilization" is taken as the representative effect of the functional substance. The functional substance generating device 3 of Embodiment 1 generates nanosized charged microparticle water containing free radicals. However, the functional substance generating device 3 may also be an ion generating device or an ozone generating device. In addition, the functional substance generating device 3 may also be a device capable of generating multiple functional substances among charged microparticle water, ions (such as negative ions), and ozone. In addition, the charged microparticle water may also be a liquid other than water.

[0045] The functional substance generating device 3 is disposed at a position upstream of the evaporator 5 in a first direction that is the flow direction of the air toward the inside of the passenger compartment 10.

[0046] The "first direction" referred to in the present disclosure is the flow direction of the air from the internal gas inlet 24 or the external gas inlet 25 described later toward the blower 4 and from the blower 4 toward the inside of the passenger compartment 10. In the first direction, the blower 4 is located upstream of the evaporator 5.

[0047] In addition, "the functional substance generating device 3 is disposed at a position upstream of the evaporator 5" means a case where the functional substance generating device 3 itself is disposed at a position upstream of the evaporator 5 in the air flow direction, and a case where the functional substance generated by the functional substance generating device 3 merges at a position upstream of the evaporator 5 in the air flow direction. In Figure 3 In the example of

[0048] When the blower 4 operates, the functional substance generated by the functional substance generating device 3 moves toward the evaporator 5 along with the air flow (i.e., together with the air flow), and then passes through the evaporator 5.

[0049] In the air conditioning system 2 according to Embodiment 1, since the functional substance moves toward the evaporator 5 and then passes through the evaporator 5 when the blower 4 operates, it is easy to expose the evaporator 5 to the functional substance. For example, even if the evaporator 5 is a large evaporator, since the functional substance passes through the evaporator 5, the entire surface of the evaporator 5 can be exposed to the functional substance. As described above, in the air conditioning system 2 according to Embodiment 1, the sterilization of the evaporator 5 can be performed better.

[0050] In addition, in the air conditioning system 2 according to Embodiment 1, the sterilization of the evaporator 5 can be performed when the blower 4 operates, that is, when the air conditioning system 2 performs cooling equipment operation or heating equipment operation.

[0051] In addition, when the functional substance generated by the functional substance generating device 3 is nano-sized charged fine particle water, the functional substance is more likely to pass through the evaporator 5 than when the functional substance is an ion. That is, when the functional substance is nano-sized charged fine particle water, there is an advantage that the sterilization of the evaporator 5 can be performed better, and furthermore, the functional substance can easily reach the inside of the passenger compartment 10.

[0052] (2) Details

[0053] Hereinafter, with reference to Figures 1 to 3 the detailed structure of the vehicle 1 including the air conditioning system 2 according to Embodiment 1 will be described.

[0056] The foot space 14 is the space in front of the driver's seat and the front passenger seat and below the instrument panel 12. The foot space 14 is the space where the feet of the user sitting in the driver's seat or the front passenger seat are located.

[0057] The equipment room 15 is partitioned from the passenger compartment 10 by the instrument panel 12 or the like.

Similarly, in Figure 3 it, one of the plurality of foot air outlets 23, i.e., the foot air outlet, is illustrated.

[0061] In addition, the air conditioning system 2 includes a functional substance pipeline D0, a housing side pipeline D1, a plurality of passenger compartment side pipelines D2, a plurality of air pipelines D3, an internal gas side pipeline D7, and an external gas side pipeline D8. In the first embodiment, three passenger compartment side pipelines D2 are provided, and in the first embodiment, three air pipelines D3 are provided.

[0062] In addition, the air conditioning system 2 includes a housing side valve 26, a plurality of compartment side valves 27, a plurality of air duct valves 28, an inlet valve 291, and a heater valve 295. In Embodiment 1, three compartment side valves 27 are provided, and in Embodiment 1, three air duct valves 28 are provided. In the following description, each compartment side valve among the plurality of compartment side valves 27 may be simply referred to as "compartment side valve 27", and each air duct valve among the plurality of air duct valves 28 may be simply referred to as "air duct valve 28". The housing side valve 26, the compartment side valve 27, the air duct valve 28, the inlet valve 291, and the heater valve 295 are controlled by the control unit 8.

[0063] The housing 20 of the present disclosure is the part surrounded by the double-dashed line in Figure 3 , Figures 8 to 13 and Figures 17 to 19 . Regarding Figures 8 to 13 and Figures 17 to 19 , they will be described in detail later. The housing 20 houses a blower 4, an evaporator 5, a heater 6, and a filter 7. In addition, a plurality of air duct valves 28, an inlet valve 291, and a heater valve 295 are provided in the housing 20.

[0064] The housing 20 has a confluence port 201. The confluence port 201 is formed at a position upstream of the evaporator 5 and downstream of the blower 4 in the first direction. The confluence port 201 is connected to the housing side duct D1. That is, the housing 20 is connected to the functional substance generating device 3 via the housing side duct D1 and the functional substance duct D0. When the functional substance generating device 3 operates and the housing side valve 26 is opened, the functional substance generated by the functional substance generating device 3 converges inside the housing 20 between the blower 4 and the evaporator 5. That is, the functional substance generated by the functional substance generating device 3 converges at a position downstream of the blower 4 and upstream of the evaporator 5 in the first direction.

[0065] In addition, the housing 20 is connected to the defrost air outlet 21, the face air outlet 22, and the foot air outlet 23 via a plurality of air ducts D3. In addition, the housing 20 is connected to the internal gas inlet 24 via the internal gas side duct D7 and is connected to the external gas inlet 25 via the external gas side duct D8.

[0066] The inlet valve 291 is a valve that can block (i.e., close) one of the internal gas side duct D7 connected to the internal gas inlet 24 and the external gas side duct D8 connected to the external gas inlet 25.

[0067] A plurality of air duct valves 28 can independently block the air duct D3 connected to the defrost air outlet 21, the air duct D3 connected to the face air outlet 22, and the air duct D3 connected to the foot air outlet 23, respectively. That is to say, the air duct valve 28 is a valve that opens and closes the flow path of the air duct D3.

[0068] As Figure 1 and Figure 2 shown, the defrost air outlet 21 is opened in such a way that the air or functional substance leading to the inside of the vehicle compartment 10 faces the front windshield 11 or the periphery of the front windshield 11.

[0069] As Figure 1 and Figure 2 shown, the face air outlet 22 is opened in such a way that the air or functional substance leading to the inside of the vehicle compartment 10 faces the upper body of the user sitting in the driver's seat or the co-driver's seat.

[0070] As Figure 1 shown, the foot air outlet 23 is opened in such a way that the air or functional substance leading to the inside of the vehicle compartment 10 faces the feet of the user sitting in the driver's seat or the co-driver's seat.

[0071] Figure 3 The internal gas inlet 24 and the external gas inlet 25 shown are inlets for introducing air into the housing 20. The internal gas inlet 24 is, for example, arranged to open towards the inside of the vehicle compartment 10. That is to say, the internal gas inlet 24 is an inlet for introducing air from the inside of the vehicle compartment 10 into the housing 20. In addition, the external gas inlet 25 is, for example, arranged to open towards the outside of the vehicle. That is to say, the external gas inlet 25 is an inlet for introducing air from outside the vehicle into the housing 20.

[0072] The functional substance pipeline D0 is a pipeline through which the functional substance generated by the functional substance generating device 3 passes. The functional substance generating device 3 is arranged at one end of the functional substance pipeline D0. In addition, the other end of the functional substance pipeline D0 is connected to the housing side pipeline D1 and the vehicle compartment side pipeline D2.

[0073] The housing side pipeline D1 is a pipeline through which the functional substance generated by the functional substance generating device 3 passes. One end of the housing side pipeline D1 is connected to the functional substance pipeline D0. In addition, the other end of the housing side pipeline D1 is connected to the confluence port 201 of the housing 20. That is to say, the housing side pipeline D1 is a pipeline connecting the functional substance generating device 3 and the housing 20.

[0074] The carriage-side pipe D2 is a pipe through which the functional substance generated by the functional substance generating device 3 passes. One end of the carriage-side pipe D2 is connected to the functional substance pipe D0. In addition, the other end of the carriage-side pipe D2 is connected to the air pipe D3. That is to say, the carriage-side pipe D2 is a pipe connecting the functional substance generating device 3 and the air pipe D3.

[0075] The air pipe D3 is arranged at a position downstream of the evaporator 5 in the first direction. The air pipe D3 is a pipe through which the air flow generated by the blower 4 or the functional substance generated by the functional substance generating device 3 passes. One end of the air pipe D3 is connected to the housing 20. In addition, the other end of the air pipe D3 is connected to any one of the defrost air outlet 21, the face air outlet 22, and the foot air outlet 23. That is to say, the air pipe D3 is a pipe connecting the interior of the carriage 10 and the housing 20. In addition, the air pipe D3 is connected to the other end of the carriage-side pipe D2 between one end and the other end of the air pipe D3.

[0076] One end of the internal gas-side pipe D7 is connected to the housing 20. In addition, the other end of the internal gas-side pipe D7 is connected to the internal gas inlet 24. That is to say, the internal gas-side pipe D7 is a pipe connecting the housing 20 and the internal gas inlet 24.

[0077] One end of the external gas-side pipe D8 is connected to the housing 20. In addition, the other end of the external gas-side pipe D8 is connected to the external gas inlet 25. That is to say, the external gas-side pipe D8 is a pipe connecting the housing 20 and the external gas inlet 25.

[0078] The housing-side valve 26 is provided at one end of the housing-side pipe D1. The housing-side valve 26 is a valve capable of blocking (i.e., closing) the housing-side pipe D1. That is to say, the housing-side valve 26 is a valve that opens and closes the flow path of the housing-side pipe D1.

[0079] The carriage-side valve 27 is provided at one end of the carriage-side pipe D2. The carriage-side valve 27 is a valve capable of blocking (i.e., closing) the carriage-side pipe D2. That is to say, the carriage-side valve 27 is a valve that opens and closes the flow path of the carriage-side pipe D2.

[0080] The blower 4 generates the flow of air. The blower 4 has a motor and operates by rotating through the shaft of the motor. The blower 4 operates based on the control of the control unit 8.

[0081] The blower 4 of Embodiment 1 is configured to be able to generate a flow of air in a first direction and a flow of air in a second direction, which is a direction opposite to the first direction. The "second direction" as referred to in the present disclosure is the flow direction of air from the vehicle compartment 10 side toward the blower 4 and from the blower 4 toward the internal gas inlet 24 or the external gas inlet 25. In the first direction, the blower 4 is located upstream of the evaporator 5. In the second direction, the blower 4 is located upstream of the filter 7, and the heater 6 is located upstream of the evaporator 5.

[0082] In addition, the blower 4 of Embodiment 1 can change the wind pressure and the air volume of the air output by the blower 4. For example, the blower 4 is configured to be able to output air at a first wind pressure or a second wind pressure. The second wind pressure is a wind pressure higher than the first wind pressure. In addition, the first wind pressure and the second wind pressure do not need to be fixed wind pressures, as long as they are within a specified range of wind pressures. Further, for example, the blower 4 is configured to be able to output air at a first air volume or a second air volume. The second air volume is an air volume larger than the first air volume. In addition, the first air volume and the second air volume do not need to be fixed air volumes, as long as they are within a specified range of air volumes. In the following description, only the case where the blower 4 changes the wind pressure is illustrated, but the blower 4 may change the air volume instead of or in addition to changing the wind pressure. For example, the case where the blower 4 outputs air at the first wind pressure may be the case where the blower 4 outputs air at the first air volume. Further, the case where the blower 4 outputs air at the second wind pressure may be the case where the blower 4 outputs air at the second air volume.

[0083] As Figure 3 shown, the evaporator 5 is disposed in the middle of the flow of air generated by the blower 4 (i.e., the flow of air flowing inside the flow path). More specifically, the evaporator 5 is disposed at a position downstream of the blower 4 in the first direction. The evaporator 5 has a heat exchange portion that is a gap through which the air flowing in the housing 20 passes. At the position where the evaporator 5 is disposed, the outer edge of the evaporator 5 (more specifically, the cross-sectional area of the evaporator 5) substantially coincides with and contacts the inner edge of the housing 20 (more specifically, the cross-sectional area of the housing 20).

[0084] The evaporator 5 of Embodiment 1 is connected from the engine room 16 (refer to Figure 1 ) to the equipment room 15 (refer to Figure 1) is connected to the refrigerant circulation flow path. In addition, the refrigerant circulation flow path is also connected to a compressor, a condenser, a receiver, and an expansion valve. When power is transmitted from the engine to the compressor, the compressor circulates the refrigerant within the circulation flow path. The refrigerant circulating within the circulation path vaporizes in the evaporator 5. When the refrigerant vaporizes, that is, when the evaporator 5 operates, the refrigerant takes heat as the heat of vaporization from the air passing through the gap (more specifically, the heat exchange section) of the evaporator 5, thereby cooling the air. The evaporator 5 is controlled by the control unit 8.

[0085] As Figure 3 shown, the heater 6 is disposed at a position downstream of the evaporator 5 in the first direction. The heater 6 has a heat exchange section that serves as a gap through which air passes. The heater 6 is configured such that when air flows in the first direction, a part of the air that has passed through the evaporator 5 passes through the heater 6 (more specifically, the heat exchange section of the heater 6). At the position where the heater 6 is disposed, the outer edge of the heater 6 (more specifically, the cross-sectional area of the heater 6) is smaller than the inner edge of the housing 20 (more specifically, the cross-sectional area of the housing 20).

[0086] The heater 6 of Embodiment 1 is connected to a diversion path of the engine coolant from the engine compartment 16 (refer to Figure 1 ) to the equipment compartment 15 (refer to Figure 1 ). The diversion path is configured such that the heater 6 is in parallel with the radiator in the circulation flow path of the engine coolant that circulates between the engine and the radiator. When the hot water valve is opened while the engine coolant circulates in the circulation flow path, the coolant heated by the engine (i.e., hot water) flows into the diversion path, and the heater 6 is heated by the hot water. Air passes through the heat exchange section of the heated heater 6, thereby heating the air. The heater 6 (more specifically, the hot water valve) is controlled by the control unit 8.

[0087] The heater valve 295 is disposed at a position upstream of the heater 6 in the first direction. The opening degree (i.e., the valve opening condition) of the heater valve 295 is controlled according to the control of the control unit 8. The amount of air passing through the heater 6 is adjusted according to the opening degree of the heater valve 295.

[0088] The filter 7 is disposed on the upstream side of the blower 4 in the first direction and on the downstream side of the internal gas inlet 24 and the external gas inlet 25. At the position where the filter 7 is disposed, the outer edge of the filter 7 (more specifically, the cross-sectional area of the filter 7) substantially coincides with and contacts the inner edge of the housing 20 (more specifically, the cross-sectional area of the housing 20). That is, the air flowing into the housing 20 from the internal gas inlet 24 and the external gas inlet 25, or the air flowing from the inside of the housing 20 toward the internal gas inlet 24 and the external gas inlet 25 passes through the filter 7. The filter 7 purifies the air flow by removing dust and dirt contained in the air flow passing through the filter 7.

[0089] The functional material generating device 3 generates a functional material. The functional material generating device 3 of Embodiment 1 includes a cooling unit including a Peltier element, a discharge electrode, an opposing electrode, and a voltage application unit. In the functional material generating device 3, the cooling unit is cooled by energizing the Peltier element, so that the discharge electrode is cooled. When the discharge electrode is cooled, dew condensation occurs in the discharge electrode. When a high voltage is applied between the discharge electrode and the opposing electrode in a state where dew condensation has occurred in the discharge electrode, a Taylor cone is formed in the discharge electrode. Charges are concentrated at the tip of the Taylor cone, increasing the electric field strength at the tip of the Taylor cone. As a result, the Coulomb force generated at the tip of the Taylor cone increases, causing the Taylor cone to grow. When the Taylor cone grows and charges are concentrated at the tip of the Taylor cone, making the charge density high, the dew condensation water at the tip portion of the Taylor cone receives a large amount of energy (more specifically, the repulsive force of the high-density charges), exceeds the surface tension, and repeats splitting / scattering (more specifically, Rayleigh splitting), thereby generating a large amount of nano-sized charged microparticle water. In addition, the functional material generating device 3 has a motor fan for facilitating the discharge of the generated functional material to the outside. The functional material generating device 3 operates based on the control of the control unit 8.

[0090] As Figure 3 shown, the functional material generating device 3 of Embodiment 1 is disposed outside the housing 20. The functional material generated by the functional material generating device 3 is transported into the housing 20 through the functional material pipe D0, the housing side pipe D1, and the confluence port 201. Since the functional material generating device 3 is disposed outside the housing 20, miniaturization of the housing 20 can be achieved. In addition, since the functional material generating device 3 is disposed outside the housing 20, maintenance and repair of the functional material generating device 3 are easy.

[0091] In addition, the functional material generating device 3 of Embodiment 1 is connected to the air duct D3 via the functional material duct D0 and the vehicle compartment side duct D2. That is, the functional material generated by the functional material generating device 3 is transported to at least one of the interior of the vehicle compartment 10 and the interior of the housing 20 through the functional material duct D0, the vehicle compartment side duct D2, and the air duct D3. For example, by controlling the housing side valve 26, the vehicle compartment side valve 27, and the air duct valve 28, the functional material generated by the functional material generating device 3 can be selectively moved.

[0092] The operation unit 9 is provided on the instrument panel 12 (refer to Figure 2 ). The operation unit 9 has, for example, a touch panel display. The operation unit 9 accepts operations performed by the user of the vehicle 1. Based on the user's operation, the operation unit 9 accepts operations such as turning on / off the air conditioning operation performed by the air conditioning system 2, switching between the operation of the cooling device and the operation of the heating device, temperature setting, air volume setting, turning on / off the functional material generating device 3, and selecting the operation mode described later.

[0093] The air conditioning system 2 includes, for example, a microcomputer having a processor and a memory. The computer system functions as the control unit 8 by the processor executing an appropriate program. That is, the control unit 8 is implemented by a computer system having a processor and a memory. The program can be either pre-recorded in the memory or provided through an electrical communication line such as the Internet or in a non-transitory recording medium such as a memory card.

[0094] The control unit 8 performs drive control of the air conditioning system 2. The control unit 8 performs drive control of the air conditioning system 2 based on the detection results of detection devices such as seat sensors, human body sensing sensors, infrared sensors, odor sensors, PM2.5 sensors, ozone sensors, temperature sensors, humidity sensors, speed sensors, acceleration sensors, gyro sensors, CO2 sensors, or cameras, or control signals corresponding to the user's operations on the operation unit 9. For example, the control unit 8 executes multiple operation modes based on the control signals. The multiple operation modes include an exposure mode (more specifically, a normal mode), a drying mode, and a filling mode. That is, the control unit 8 is configured to be able to execute the exposure mode, the drying mode, and the filling mode. In addition, the detection devices can be either components of the air conditioning system 2 or components different from the air conditioning system 2 of the vehicle 1.

[0095] The exposure mode is an operation mode in which the evaporator 5 is exposed to an air flow containing the functional material generated by the functional material generating device 3. When the air conditioning system 2 operates in the exposure mode, the control unit 8 operates the blower 4 so that air is output from the blower 4 at a first air pressure.

[0096] The drying mode is an operation mode for drying the evaporator 5. When the air conditioning system 2 operates in the drying mode, the control unit 8 operates the blower 4 so that air is output from the blower 4 at a second air pressure higher than the first air pressure. When the evaporator 5 operates, dew condensation may sometimes occur in the evaporator 5 due to the temperature difference between the air and the evaporator 5. By drying the evaporator 5 in the drying mode, an environment in which mold is not easily generated and grown can be created.

[0097] In addition, when the air conditioning system 2 operates in the drying mode, the control unit 8 of Embodiment 1 operates the heater 6 and operates the blower 4 to generate a flow of air in a second direction, which is a direction opposite to the first direction. Further, when the blower 4 generates a flow of air in the second direction, it is preferable to open at least one of the plurality of air duct valves 28. By operating the blower 4 to generate a flow of air in the second direction and operating the heater 6 located upstream of the evaporator 5 in the second direction, the evaporator 5 can be exposed to warm air, and the evaporator 5 can be dried well. In addition, the control unit 8 does not need to control the blower 4 in such a way as to generate a flow of air in the second direction.

[0098] The filling mode is an operation mode in which the evaporator 5 is exposed to the functional substance by filling the inside of the housing 20 with the functional substance. When the air conditioning system 2 operates in the filling mode, the control unit 8 operates the functional substance generating device 3, stops the blower 4, opens the housing side valve 26, and closes the air duct valve 28, thereby filling the inside of the housing 20 with the functional substance. By filling the inside of the housing 20 with the functional substance, the entire surface of the evaporator 5 can be exposed to the functional substance. In addition, by filling the inside of the housing 20 with the functional substance, not only the evaporator 5 can be disinfected, but also the inner surface of the housing 20, the blower 4, the filter 7, etc. can be disinfected.

[0099] Alternatively, after a predetermined time has elapsed since the start of the execution of the filling mode, the control unit 8 may open at least one of the plurality of air duct valves 28, control the inlet valve 291 so that air flows toward the outside gas side duct D8, and operate the blower 4 to generate a flow of air in the second direction. By controlling to generate a second direction of air flow opposite to the first direction toward the inside of the compartment 10 and discharging the air to the outside of the vehicle, the functional substance filled in the housing 20 can be discharged to the outside of the vehicle without being discharged into the compartment 10. Especially when the functional substance generating device 3 generates ozone, the ozone filled in the housing 20 can be suppressed from moving into the compartment 10.

[0100] (3) Operation of the air conditioning system

[0101] Next, with reference to Figures 4 to 7To explain the operation of the air conditioning system 2. Figure 4 It is a flowchart showing the operation of the air conditioning system 2 according to Embodiment 1. Figure 5 It is a flowchart showing the operation of the exposure mode of the air conditioning system 2 according to Embodiment 1. Figure 6 It is a flowchart showing the operation of the drying mode of the air conditioning system 2 according to Embodiment 1. Figure 7 It is a flowchart showing the operation of the filling mode of the air conditioning system 2 according to Embodiment 1. In Figure 4 The series of processes shown in the flowchart are processes for sterilizing the evaporator 5, and are processes started, for example, by a user performing a prescribed operation on the operation unit 9.

[0102] First, the control unit 8 executes the exposure mode (S1). Next, the control unit 8 determines whether a control signal is received from the operation unit 9 (S2). Here, the control signal is, for example, a signal sent from the operation unit 9 to the control unit 8 when the operation unit 9 receives a prescribed operation by the user. When the control unit 8 does not receive the control signal (S2: "No"), the control unit 8 repeats the process of step S2 while executing the exposure mode, for example. On the other hand, when the control unit 8 receives the control signal (S2: "Yes"), the control unit 8 executes the drying mode (S3). After executing the drying mode, the control unit 8 executes the filling mode (S4) and ends the process.

[0103] Figure 4 The flowchart shown is merely an example, and the order of processes can be appropriately changed, and processes can be appropriately added or deleted. For example, the control unit 8 may execute only one of the drying mode and the filling mode after executing the exposure mode.

[0104] As described above, the control unit 8 of Embodiment 1 executes at least one of the drying mode and the filling mode after executing the exposure mode. After sterilizing the evaporator 5 in the exposure mode, further drying the evaporator 5 or sterilizing the evaporator 5 can thus perform better sterilization of the evaporator 5. In addition, the control unit 8 may, for example, execute the exposure mode again after executing the filling mode.

[0105] In addition, the control unit 8 of Embodiment 1 sequentially executes the exposure mode, the drying mode, and the filling mode. After sterilizing the evaporator 5 in the exposure mode, drying the evaporator 5 and further sterilizing the evaporator 5 can thus perform better sterilization of the evaporator 5.

[0106] Next, refer to Figure 5Description of the processing in the exposure mode (S1). When executing the exposure mode, the control unit 8 turns on the functional material generating device 3 (S11). That is, when executing the exposure mode, the control unit 8 operates the functional material generating device 3. Next, the control unit 8 controls the blower 4 (S12). More specifically, the control unit 8 controls the blower 4 so that the blower 4 outputs air in the first direction at the first air pressure. Next, the control unit 8 opens the air duct valve 28 (S13).

[0107] Next, the control unit 8 controls the housing side valve 26 and the vehicle compartment side valve 27 (S14) and ends the exposure mode. More specifically, the control unit 8 controls the housing side valve 26 and the vehicle compartment side valve 27 to open the housing side valve 26. Since the housing side valve 26 is in the open state, the functional material generated by the functional material generating device 3 moves into the housing 20. The functional material that has moved into the housing 20 passes through the evaporator 5 together with the air flow in the first direction generated by the blower 4 and moves into the vehicle compartment 10.

[0108] Next, refer to Figure 6 Description of the processing in the drying mode (S3). When executing the drying mode, the control unit 8 controls the blower 4 (S21). More specifically, the control unit 8 controls the blower 4 so that the blower 4 outputs air in the first direction at the second air pressure.

[0109] Next, the control unit 8 controls the housing side valve 26 and the vehicle compartment side valve 27 (S22). More specifically, the control unit 8 controls the housing side valve 26 and the vehicle compartment side valve 27 to close the housing side valve 26 and open the vehicle compartment side valve 27. Since the housing side valve 26 is in the closed state and the vehicle compartment side valve 27 is in the open state, the evaporator 5 can be dried and the functional material generated by the functional material generating device 3 can move into the vehicle compartment 10. In addition, the control unit 8 can also control the housing side valve 26 and the vehicle compartment side valve 27 to open the housing side valve 26 and close the vehicle compartment side valve 27 so that the functional material moves into the housing 20.

[0110] Next, the control unit 8 determines whether a predetermined time (hereinafter referred to as "first predetermined time") has elapsed since the execution of the drying mode (S23). The first predetermined time is appropriately set according to the wind pressure of the air output by the blower 4, the size of the evaporator 5, etc., or the user operation on the operation unit 9. In addition, the control unit 8 may determine whether the detection result of the detection device is a predetermined result, or whether a predetermined operation has been performed on the operation unit 9, instead of determining whether the first predetermined time has elapsed since the execution of the drying mode. When the first predetermined time has not elapsed since the execution of the drying mode (S23: "No"), the control unit 8 repeats the process of step S23. On the other hand, when the first predetermined time has elapsed since the execution of the drying mode (S23: "Yes"), the control unit 8 controls the blower 4 (S24). More specifically, the control unit 8 controls the blower 4 so that the air is output in the second direction. In addition, the wind pressure of the air output by the blower 4 may be either the first wind pressure or the second wind pressure, or a third wind pressure different from the first wind pressure and the second wind pressure.

[0111] Next, the control unit 8 turns on the heater 6 (S25). That is, the control unit 8 operates the heater 6. Then, the control unit 8 controls the housing side valve 26 and the compartment side valve 27 (S26). More specifically, the control unit 8 controls the housing side valve 26 and the compartment side valve 27 to open the housing side valve 26 and close the compartment side valve 27.

[0112] Next, the control unit 8 determines whether a predetermined time (hereinafter referred to as "second predetermined time") has elapsed since the execution of the process of step S26 (S26). The second predetermined time is appropriately set according to the wind pressure of the air output by the blower 4, the size of the evaporator 5, the temperature of the heater 6, etc., or the user operation on the operation unit 9. In addition, the control unit 8 may determine whether the detection result of the detection device is a predetermined result, or whether a predetermined operation has been performed on the operation unit 9, instead of determining whether the second predetermined time has elapsed since the execution of the process of step S26. When the second predetermined time has not elapsed since the execution of the process of step S26 (S26: "No"), the control unit 8 repeats the process of step S26. On the other hand, when the second predetermined time has elapsed since the execution of the process of step S26 (S26: "Yes"), the control unit 8 ends the drying mode.

[0113] Next, the description of the process of the filling mode (S4) will be made with reference to Figure 7 When the control unit 8 executes the filling mode, it turns off the heater 6 (S31), turns off the blower 4 (S32), and closes the air duct valve 28 (S33).

[0114] Next, the control unit 8 controls the housing side valve 26 and the vehicle compartment side valve 27 (S34). More specifically, the control unit 8 controls the housing side valve 26 and the vehicle compartment side valve 27 to open the housing side valve 26 and close the vehicle compartment side valve 27. By disconnecting the blower 4 and controlling each valve by the control unit 8, the functional substance is filled in the housing 20.

[0115] Next, the control unit 8 determines whether a predetermined time (hereinafter referred to as "third predetermined time") has elapsed since the processing of step S34 was executed (S35). The third predetermined time is appropriately set according to the size of the housing 20 or the like, or the operation of the user on the operation unit 9. In addition, instead of determining whether the third predetermined time has elapsed since the processing of step S34 was executed, the control unit 8 may determine whether the detection result of the detection device is a predetermined result, or whether a predetermined operation has been performed on the operation unit 9. In the case where the third predetermined time has not elapsed since the processing of step S34 was executed (S35: "No"), the control unit 8 repeats the processing of step S35. On the other hand, in the case where the third predetermined time has elapsed since the processing of step S34 was executed (S35: "Yes"), the control unit 8 controls the blower 4 (S36). More specifically, the control unit 8 controls the blower 4 so that air is output in the first direction.

[0116] Next, the control unit 8 determines whether a predetermined time (hereinafter referred to as "fourth predetermined time") has elapsed since the processing of step S36 was executed (S37). The fourth predetermined time is appropriately set according to the air pressure of the air output by the blower 4, the size of the evaporator 5, or the like, or the operation of the user on the operation unit 9. In addition, instead of determining whether the fourth predetermined time has elapsed since the processing of step S36 was executed, the control unit 8 may determine whether the detection result of the detection device is a predetermined result, or whether a predetermined operation has been performed on the operation unit 9. In the case where the fourth predetermined time has not elapsed since the processing of step S36 was executed (S37: "No"), the control unit 8 repeats the processing of step S37. On the other hand, in the case where the fourth predetermined time has elapsed since the processing of step S36 was executed (S37: "Yes"), the control unit 8 controls the blower 4 (S38). More specifically, the control unit 8 controls the blower 4 so that air is output in the second direction.

[0117] Next, the control unit 8 controls the inlet valve 291 (S39) and ends the filling mode. Specifically, the control unit 8 controls the inlet valve 291 so that air flows toward the external gas side pipe D8. By generating the flow of air from the blower 4 toward the external gas inlet 25, the filter 7 can be exposed to the functional substance, thereby sterilizing the filter 7. In addition, in the case where the functional substance is ozone, the ozone can be moved outside the vehicle.

[0118] Figures 5 to 7The flowchart shown is just an example, and the order of processing can be appropriately changed, and processing can also be appropriately added or deleted.

[0119] For example, in the process of step S38 of Figure 7 , the control unit 8 can, in addition to controlling the blower 4, also control to close the housing side valve 26 and open the vehicle compartment side valve 27. That is to say, in the filling mode, the control unit 8 opens the vehicle compartment side valve 27 and operates the blower 4 to generate a flow of air in the second direction, which is the direction opposite to the first direction. By generating a flow of air from the blower 4 toward the external gas inlet 25, it is possible to sterilize the filter 7 while delivering the functional substance into the vehicle compartment 10.

[0120] (4) Variant example

[0121] Hereinafter, variant examples of Embodiment 1 will be listed.

[0122] (4.1) First variant example

[0123] Figure 8 is a schematic diagram showing the structure of the air conditioning system 2 according to the first variant example of Embodiment 1. As Figure 8 shown, the confluence port 201 can also be formed between the blower 4 and the filter 7. In other words, the confluence port 201 can also be formed at a position upstream of the blower 4 in the first direction. The air conditioning system 2 of the first variant example can also expose the evaporator 5 to the functional substance generated by the functional substance generating device 3 in the exposure mode, for example, in the same manner as the air conditioning system 2 of Embodiment 1.

[0124] (4.2) Second variant example

[0125] Figure 9 is a schematic diagram showing the structure of the air conditioning system 2 according to the second variant example of Embodiment 1. As Figure 9 shown, it can also be that the confluence port 201 is formed between the blower 4 and the filter 7, and a confluence port 202 different from the confluence port 201 is formed at a position upstream of the filter 7 in the first direction. One end of the housing side pipe D1 is connected to the functional substance pipe D0, and the other end of the housing side pipe D1 branches into a first housing side pipe D11 and a second housing side pipe D12. The first housing side pipe D11 is connected to the confluence port 201, and the second housing side pipe D12 is connected to the confluence port 202.

[0126] The air conditioning system 2 according to the second modification example can select the moving destination of the functional substance generated by the functional substance generating device 3 from between the blower 4 and the filter 7 and the upstream side of the filter 7 in the first direction. For example, in the filling mode, the control unit 8 turns on the functional substance generating device 3, turns off the blower 4, and controls the housing side valve 26, the vehicle compartment side valve 27, and the valve 296, whereby the filter 7 can be filled with the functional substance between the internal gas inlet 24 and the external gas inlet 25.

[0127] (4.3) Third modification example

[0128] Figure 10 is a schematic diagram showing the structure of the air conditioning system 2 according to the third modification example of Embodiment 1. As Figure 10 shown, a confluence port 201 may be formed between the blower 4 and the evaporator 5, and a confluence port 202 may be formed at a position upstream of the filter 7 in the first direction. The first housing side pipe D11 is connected to the confluence port 201, and the second housing side pipe D12 is connected to the confluence port 202.

[0129] The valve 297 is a valve that can block (i.e., close) one of the first housing side pipe D11 and the second housing side pipe D12.

[0130] The air conditioning system 2 according to the third modification example can select the moving destination of the functional substance generated by the functional substance generating device 3 from between the blower 4 and the evaporator 5 and the upstream side of the filter 7 in the first direction.

[0131] (4.4) Fourth modification example

[0132] Figure 11 is a schematic diagram showing the structure of the air conditioning system 2 according to the fourth modification example of Embodiment 1. As Figure 11 shown, the air conditioning system 2 may further include: a second direction blower 4a that generates a flow of air in a second direction, where the second direction is a direction opposite to the first direction; a filter 7a; and a pipe D9 that connects the filter 7a to the external gas inlet 25. The second direction blower 4a of the fourth modification example generates a flow of air in a direction from the external gas inlet 25 through the pipe D9 toward the filter 7a and from the filter 7a toward the second direction blower 4a. In addition, the blower 4 (i.e., the first direction blower) of the fourth modification example can only generate a flow of air in, for example, the first direction.

[0133] The second-direction blower 4a and the filter 7a are arranged outside the housing 20. The space Sp1 in which the second-direction blower 4a is arranged is connected to the other end of the housing-side duct D1, one end of the duct D4, and one end of the duct D5. In addition, the space Sp1 in which the second-direction blower 4a is arranged is connected to the duct D9 via the filter 7a. However, the second-direction blower 4a and the filter 7a may also be arranged inside the housing 20.

[0134] The confluence port 201 is formed between the blower 4 and the evaporator 5. In addition, the confluence port 202 is formed at a position on the downstream side of the evaporator 5 in the first direction and on the upstream side of the air duct D3.

[0135] One end of the housing-side duct D1 is connected to the functional substance duct D0, and the other end of the housing-side duct D1 is connected to the space Sp1 in which the second-direction blower 4a is arranged. One end of the duct D4 is connected to the space Sp1, and the other end of the duct D4 is connected to the confluence port 202. The confluence port 202 of the fourth modification example is provided at a position upstream of the heater 6 in the second direction. In addition, one end of the duct D5 is connected to the space Sp1, and the other end of the duct D5 is connected to the confluence port 201.

[0136] The valve 261 opens and closes the flow path of the duct D4, and the valve 262 opens and closes the flow path of the duct D5.

[0137] The air-conditioning system 2 of the fourth modification example (more specifically, the control unit 8) performs the following processing in the drying mode instead of Figure 6 Steps S24 to S26.

[0138] The control unit 8 turns off the blower 4, turns on the second-direction blower 4a, opens the valve 261, and closes the valve 262. By operating the second-direction blower 4a, the air flow that sequentially passes through the outside gas inlet 25, the duct D9, the filter 7a, the space Sp1, the duct D4, the heater 6, the evaporator 5, the blower 4, the filter 7, and the inside gas inlet 24 or the outside gas inlet 25 is formed. That is, by operating the second-direction blower 4a, the air flow in the second direction from the compartment 10 side toward the blower 4 and from the blower 4 toward the inside gas inlet 24 or the outside gas inlet 25 is formed. In addition, the control unit 8 turns on the heater 6. In addition, the control unit 8 closes the housing-side valve 26 and opens the compartment-side valve 27. However, the control unit 8 may also open the housing-side valve 26 and close the compartment-side valve 27.

[0139] That is to say, the control unit 8 of the fourth modification example is configured to be able to execute a drying mode. In this drying mode, the heater 6 is operated, the blower 4 is not operated, and the second-direction blower 4a is operated to dry the evaporator 5. According to the control unit 8 of the fourth modification example, even when the blower 4 is not configured to be able to generate a reverse flow of air (i.e., the second direction), the evaporator 5 can be exposed to warm air, so that the evaporator 5 can be dried well.

[0140] In addition, the control unit 8 of the fourth modification example performs the following processing in the filling mode instead of Figure 7 step S38.

[0141] The control unit 8 disconnects the blower 4, turns on the second-direction blower 4a, opens the valve 261, and closes the valve 262, thereby generating a second-direction flow of air. Since a second-direction flow of air is generated, the functional substance filled in the housing 20 can be moved to the outside of the vehicle via the pipe D9 and the external gas inlet 25 and the like.

[0142] In addition, the pipe D9 may be a pipe that connects the internal gas inlet 24 and the space Sp1 via the filter 7a.

[0143] (4.5) Fifth modification example

[0144] Figure 12 It is a schematic diagram showing the structure of the air conditioning system 2 according to the fifth modification example of Embodiment 1. As Figure 12 shown, a confluence port 201 may be formed between the blower 4 and the evaporator 5, and a confluence port 202 may be formed at a position on the downstream side of the evaporator 5 in the first direction and on the upstream side of the air pipe D3. In order to distinguish the confluence port 201 and the confluence port 202 from each other, the confluence port 201 and the confluence port 202 are sometimes referred to as the first confluence port 201 and the second confluence port 202, respectively. The first housing-side pipe D11 is connected to the confluence port 201, and the second housing-side pipe D12 is connected to the confluence port 202. The confluence port 202 is arranged at a position upstream of the heater 6 in the second direction.

[0145] According to the air conditioning system 2 of the fifth modification example, the moving destination of the functional substance generated by the functional substance generating device 3 can be selected from between the blower 4 and the evaporator 5 and the downstream side of the evaporator 5 in the first direction.

[0146] (4.6) Other modification examples

[0147] The control of the functional material generating device 3, the blower 4, the heater 6, and each valve described in Embodiment 1 and the first to fifth modified examples can also be appropriately changed within the scope not departing from the intention of each operation mode. In addition, the control of each valve includes not only the control of fully opening and fully closing but also the control of opening and closing angles of each valve to open a part of the flow path or close a part of the flow path.

[0148] In Embodiment 1, the case where the air conditioning system 2 includes a plurality of vehicle compartment side ducts D2 is illustrated. In Embodiment 1, three vehicle compartment side ducts D2 are provided. However, the air conditioning system 2 may include at least one of the plurality of vehicle compartment side ducts D2, or may not include the vehicle compartment side ducts D2.

[0149] (Embodiment 2)

[0150] Next, the air conditioning system 2 according to Embodiment 2 will be described.

[0151] (1) Structure

[0152] Figure 13 is a schematic diagram showing the structure of the air conditioning system 2 according to Embodiment 2. As Figure 13 shown, in the air conditioning system 2 according to Embodiment 2, the functional material generating device 3 is disposed inside the housing 20. More specifically, the functional material generating device 3 is disposed between the blower 4 and the evaporator 5.

[0153] Since the functional material generating device 3 is disposed inside the housing 20, it is not necessary to move the functional material generated by the functional material generating device 3 from outside the housing 20 to inside the housing 20, and it is possible to suppress the reduction of the functional material during the movement of the functional material. In addition, the functional material generating device 3 is disposed at a position upstream of the evaporator 5 in the first direction. Similar to the air conditioning system 2 of Embodiment 1, in the air conditioning system 2 of Embodiment 2, when the blower 4 operates, the functional material moves toward the evaporator 5 and passes through the evaporator 5, so it is easy to expose the evaporator 5 to the functional material.

[0154] In addition, in the air conditioning system 2 according to Embodiment 2, since the functional material generating device 3 is disposed between the blower 4 and the evaporator 5, compared with the case where the functional material generating device 3 is disposed at a position upstream of the blower 4 in the first direction, for example, it is possible to expose the evaporator 5 to the functional material better. In addition, according to the air conditioning system 2 according to Embodiment 2, it is possible to fill the entire housing 20 with the functional material in the filling mode.

[0155] (2) Operation of the air conditioning system

[0156] Next, with reference to Figure 4 、 Figures 14 to 16To describe the operation of the air conditioning system 2 of Embodiment 2. Figure 14 It is a flowchart showing the operation of the exposure mode of the air conditioning system 2 according to Embodiment 2. Figure 15 It is a flowchart showing the operation of the drying mode of the air conditioning system 2 according to Embodiment 2. Figure 16 It is a flowchart showing the operation of the filling mode of the air conditioning system 2 according to Embodiment 2. The air conditioning system 2 of Embodiment 2, like the air conditioning system 2 of Embodiment 1, starts by, for example, a user performing a specified operation on the operation unit 9. Figure 4 The processing shown.

[0157] First, refer to Figure 14 To describe the processing of the exposure mode (S1). When the air conditioning system 2 (more specifically, the control unit 8) executes the exposure mode, it turns on the functional substance generating device 3 (S41). That is, when the air conditioning system 2 (more specifically, the control unit 8) executes the exposure mode, it operates the functional substance generating device 3. Next, the control unit 8 controls the blower 4 (S42). More specifically, the control unit 8 controls the blower 4 so that the blower 4 outputs air in the first direction at the first air pressure. Next, the control unit 8 opens the air duct valve 28 (S43) and ends the exposure mode.

[0158] Next, refer to Figure 15 To describe the processing of the drying mode (S3). When the control unit 8 executes the drying mode, it controls the blower 4 (S51). More specifically, the control unit 8 controls the blower 4 so that the blower 4 outputs air in the first direction at the second air pressure.

[0159] Next, the control unit 8 determines whether a specified time (hereinafter referred to as "first specified time") has elapsed since the execution of the drying mode (S52). In addition, instead of determining whether the first specified time has elapsed since the execution of the drying mode, the control unit 8 may also determine whether the detection result of the detection device is a specified result, or whether a specified operation has been performed on the operation unit 9. When the first specified time has not elapsed since the execution of the drying mode (S52: "No"), the control unit 8 repeats the processing of step S52. On the other hand, when the first specified time has elapsed since the execution of the drying mode (S52: "Yes"), the control unit 8 controls the blower 4 (S53). More specifically, the control unit 8 controls the blower 4 so that the air is output in the second direction.

[0160] Next, the control unit 8 turns on the heater 6 (S54). That is, the control unit 8 activates the heater 6. Then, the control unit 8 determines whether a predetermined time (hereinafter referred to as "second predetermined time") has elapsed since the processing of step S54 was executed (S55). In addition, instead of determining whether the second predetermined time has elapsed since the processing of step S54 was executed, the control unit 8 may determine whether the detection result of the detection device is a predetermined result, or whether a predetermined operation has been performed on the operation unit 9. In the case where the second predetermined time has not elapsed since the processing of step S54 was executed (S55: "No"), the control unit 8 repeats the processing of step S55. On the other hand, in the case where the second predetermined time has elapsed since the processing of step S54 was executed (S55: "Yes"), the control unit 8 ends the drying mode.

[0161] Next, an explanation of the processing of the filling mode (S4) will be given with reference to Figure 16 When the control unit 8 executes the filling mode, it turns off the heater 6 (S61), turns off the blower 4 (S62), and closes the air duct valve 28 (S63).

[0162] Next, the control unit 8 determines whether a predetermined time (hereinafter referred to as "third predetermined time") has elapsed since the processing of step S63 was executed (S64). In addition, instead of determining whether the third predetermined time has elapsed since the processing of step S63 was executed, the control unit 8 may determine whether the detection result of the detection device is a predetermined result, or whether a predetermined operation has been performed on the operation unit 9. In the case where the third predetermined time has not elapsed since the processing of step S63 was executed (S64: "No"), the control unit 8 repeats the processing of step S64. On the other hand, in the case where the third predetermined time has elapsed since the processing of step S63 was executed (S64: "Yes"), the control unit 8 controls the blower 4 (S65). More specifically, the control unit 8 controls the blower 4 so that air is output in the first direction.

[0163] Next, the control unit 8 determines whether a predetermined time (hereinafter referred to as "fourth predetermined time") has elapsed since the processing of step S65 was executed (S66). In addition, instead of determining whether the fourth predetermined time has elapsed since the processing of step S65 was executed, the control unit 8 may determine whether the detection result of the detection device is a predetermined result, or whether a predetermined operation has been performed on the operation unit 9. In the case where the fourth predetermined time has not elapsed since the processing of step S65 was executed (S66: "No"), the control unit 8 repeats the processing of step S66. On the other hand, in the case where the fourth predetermined time has elapsed since the processing of step S65 was executed (S66: "Yes"), the control unit 8 controls the blower 4 (S67). More specifically, the control unit 8 controls the blower 4 so that air is output in the second direction.

[0164] Next, the control unit 8 controls the inlet valve 291 (S68) and ends the filling mode. Specifically, the control unit 8 controls the inlet valve 291 so that air flows to the external gas side pipe D8.

[0165] Figures 14 to 16 The flowchart shown is merely an example, and the order of processing can be appropriately changed, and processing can be appropriately added or deleted.

[0166] (3) Variation

[0167] Hereinafter, variations of the second embodiment will be listed.

[0168] (3.1) First variation

[0169] Figure 17 is a schematic diagram showing the structure of the air conditioning system 2 according to the first variation of the second embodiment. As Figure 17 shown, the functional substance generating device 3 may also be arranged at a position upstream of the filter 7 in the first direction. Since the functional substance generating device 3 is at a position upstream of the filter 7 in the first direction, the filter 7 can be sterilized when the blower 4 generates a flow of air in the first direction.

[0170] In addition, the air conditioning system 2 of the first variation includes a bypass pipe D6. One end of the bypass pipe D6 is connected to the space between the blower 4 and the evaporator 5 in the housing 20. In addition, the other end of the bypass pipe D6 is connected to the space between the filter 7 and the internal gas inlet 24 and the external gas inlet 25 in the housing 20. A valve 292 is provided on the other end side of the bypass pipe D6 for opening and closing the flow path of the bypass pipe D6.

[0171] For example, in the filling mode, by opening the valve 292, the space between the blower 4 and the evaporator 5 can be filled with the functional substance. That is, according to the air conditioning system 2 of the first variation, it is possible to select a place to be filled with the functional substance in the filling mode from between the blower 4 and the evaporator 5 and the upstream side of the filter 7 in the first direction.

[0172] (3.2) Second variation

[0173] Figure 18 is a schematic diagram showing the structure of the air conditioning system 2 according to the second variation of the second embodiment. As Figure 18 shown, one end of the bypass pipe D6 may also be connected to the space between the blower 4 and the filter 7 in the housing 20.

[0174] For example, in the filling mode, by opening the valve 292, it is possible to fill the space between the blower 4 and the filter 7 with the functional substance. That is to say, according to the air conditioning system 2 of the second modification example, it is possible to select the location where the functional substance is filled in the filling mode from among the space between the blower 4 and the filter 7 and the upstream side of the filter 7 in the first direction.

[0175] (3.3) Third modification example

[0176] Figure 19 It is a schematic diagram showing the structure of the air conditioning system 2 according to the third modification example of Embodiment 2. As Figure 19 shown, the air conditioning system 2 may further include: a second-direction blower 4a that generates a flow of air in a second direction, which is a direction opposite to the first direction; a filter 7a; and a duct D9 that connects the filter 7a to the external gas inlet 25. The second-direction blower 4a of the fourth modification example generates a flow of air in a direction from the external gas inlet 25 through the duct D9 toward the filter 7a and from the filter 7a toward the second-direction blower 4a. In addition, the blower 4 (i.e., the first-direction blower) of the fourth modification example can only generate, for example, a flow of air in the first direction.

[0177] The second-direction blower 4a and the filter 7a are arranged outside the housing 20. The space Sp1 in which the second-direction blower 4a is arranged is connected to one end of the duct D4 and one end of the duct D5. In addition, the space Sp1 in which the second-direction blower 4a is arranged is connected to the duct D9 via the filter 7a. However, the second-direction blower 4a and the filter 7a may also be arranged inside the housing 20.

[0178] The functional substance generating device 3 is arranged between the blower 4 and the evaporator 5.

[0179] One end of the duct D4 is connected to the space Sp1. In addition, the other end of the duct D4 is connected to a space between the evaporator 5 and the air duct D3 inside the housing 20 and upstream of the heater 6 in the second direction. One end of the duct D5 is connected to the space Sp1. In addition, the other end of the duct D5 is connected to a space between the blower 4 and the evaporator 5 inside the housing 20.

[0180] The valve 293 opens and closes the flow path of the duct D4, and the valve 294 opens and closes the flow path of the duct D5.

[0181] The air conditioning system 2 of the third modification example (more specifically, the control unit 8) performs the following processing in the drying mode instead of Figure 15 steps S53 and S54.

[0182] The control unit 8 disconnects the blower 4, connects the second-direction blower 4a, opens the valve 293, and closes the valve 294. The second-direction blower 4a operates, thereby forming a flow of air that sequentially passes through the external gas inlet 25, the duct D9, the filter 7a, the space Sp1, the duct D4, the heater 6, the evaporator 5, the functional substance generation device, the blower 4, the filter 7, and the internal gas inlet 24 or the external gas inlet 25. That is, the second-direction blower 4a operates, thereby forming a second-direction flow of air from the side of the passenger compartment 10 toward the blower 4 and from the blower 4 toward the internal gas inlet 24 or the external gas inlet 25. The control unit 8 connects the heater 6. The control unit 8 closes the housing-side valve 26 and opens the passenger-compartment-side valve 27.

[0183] In addition, instead of Figure 16 step S67 of

[0184] the control unit 8 of the third modification performs the following process in the filling mode.

[0185] The control unit 8 disconnects the blower 4, connects the second-direction blower 4a, opens the valve 293, and closes the valve 294, thereby generating a second-direction flow of air.

[0186] (3.4) Other modifications

[0187] The control of the functional substance generation device 3, the blower 4, the heater 6, and each valve described in the second embodiment and its first to third modifications can also be appropriately changed within the scope not departing from the intention of each operation mode. In addition, the control of each valve includes not only the control of fully opening and fully closing but also the control of opening and closing angles of each valve to open a part of the flow path or close a part of the flow path.

[0188] (Summary)

[0189] As described above, the air-conditioning system (2) according to the first aspect includes a blower (4), an evaporator (5), a housing (20), and a functional substance generation device (3). The blower (4) generates a flow of air toward the inside of the passenger compartment (10). The evaporator (5) is disposed in the middle of the air flow path and is used for heat exchange of the air. The housing (20) houses the blower (4) and the evaporator (5). The functional substance generation device (3) generates a functional substance. The functional substance generation device (3) is disposed at a position upstream of the evaporator (5) in the first direction, which is the flow direction of the air toward the inside of the passenger compartment (10).

[0190] According to this method, when the blower (4) operates, the functional substance faces the evaporator (5) and passes through the evaporator (5), so it is easy for the evaporator (5) to be exposed to the functional substance. For example, even if the evaporator (5) is large, since the functional substance passes through the evaporator (5), the entire surface of the evaporator (5) can be exposed to the functional substance. That is to say, the disinfection of the evaporator (5) can be carried out better. In addition, when the blower (4) operates, that is, when the air-conditioning system (2) performs cooling equipment operation or heating equipment operation, the disinfection of the evaporator (5) can be carried out.

[0191] The air-conditioning system (2) according to the second method further includes a housing-side pipe (D1) in the first method. The housing-side pipe (D1) connects the housing (20) and the functional substance generating device (3). The housing (20) has a confluence port (201) located at a position upstream of the evaporator (5) in the first direction. The functional substance generating device (3) is arranged outside the housing (20). The functional substance is transported into the housing (20) through the housing-side pipe (D1) and the confluence port (201).

[0192] According to this method, since the functional substance generating device (3) is arranged outside the housing (20), the miniaturization of the housing (20) can be achieved. In addition, since the functional substance generating device (3) is arranged outside the housing (20), the maintenance and repair of the functional substance generating device (3) are easy.

[0193] The air-conditioning system (2) according to the third method further includes an air pipe (D3) and a carriage-side pipe (D2) in the second method. The air pipe (D3) is arranged at a position downstream of the evaporator (5) in the first direction and connects the inside of the carriage (10) and the housing (20). The carriage-side pipe (D2) connects the air pipe (D3) and the functional substance generating device (3). The functional substance is transported to at least one of the inside of the carriage (10) and the inside of the housing (20) through the carriage-side pipe (D2).

[0194] According to this method, the functional substance generated by the functional substance generating device (3) can be selectively moved by controlling, for example, a valve provided in the housing (20) or the pipe.

[0195] In the air-conditioning system (2) according to the fourth method, in the first method, the functional substance generating device (3) is arranged inside the housing (20).

[0196] According to this method, there is no need to move the functional substance generated by the functional substance generating device (3) from outside the housing (20) to inside the housing (20), and the reduction of the functional substance during the movement of the functional substance can be suppressed.

[0197] In the air-conditioning system (2) according to the fifth mode, in the fourth mode, the functional substance generating device (3) is arranged between the blower (4) and the evaporator (5).

[0198] According to this mode, for example, compared with the case where the functional substance generating device (3) is arranged at the upstream side of the blower (4) in the first direction, the evaporator (5) can be more favorably exposed to the functional substance.

[0199] The air-conditioning system (2) according to the sixth mode is such that, in any one of the first mode to the fifth mode, it further includes a control unit (8). The control unit (8) performs drive control of the air-conditioning system (2). The control unit (8) is configured to be able to execute an exposure mode, in which the blower (4) operates so that air is output from the blower (4) at a first air pressure to expose the evaporator (5) to the functional substance. The control unit (8) is configured to be able to execute a drying mode, in which the blower (4) operates so that air is output from the blower (4) at a second air pressure higher than the first air pressure to dry the evaporator (5).

[0200] According to this mode, an environment in which molds are not easily generated and grown can be created.

[0201] The air-conditioning system (2) according to the seventh mode is such that, in any one of the first mode to the sixth mode, it further includes an air duct (D3), an air duct valve (28), and a control unit (8). The air duct (D3) is arranged at a position downstream of the evaporator (5) in the first direction and connects the inside of the passenger compartment (10) to the housing (20). The air duct valve (28) opens and closes the flow path of the air duct (D3). The control unit (8) performs drive control of the air-conditioning system (2). The control unit (8) is configured to be able to execute a filling mode, in which the air duct valve (28) is closed to fill the inside of the housing (20) with the functional substance.

[0202] According to this mode, by filling the inside of the housing (20) with the functional substance, the entire surface of the evaporator (5) can be exposed to the functional substance. In addition, not only can the evaporator (5) be disinfected, but also the inner surface of the housing (20), the blower (4), the filter (7), etc. can be disinfected.

[0203] The air-conditioning system (2) according to the eighth mode is such that, in the seventh mode, after a predetermined time has elapsed since the start of execution of the filling mode, the control unit (8) operates the blower (4) to generate a flow of air in a second direction, where the second direction is opposite to the first direction.

[0204] According to this method, by generating a flow of air in a second direction opposite to the first direction towards the interior of the passenger compartment (10), it is possible to prevent the functional substance filling the interior of the housing (20) from being discharged into the passenger compartment (10) and instead discharge it outside the vehicle, for example. In particular, when the functional substance generating device (3) generates ozone, it is possible to inhibit the ozone filling the interior of the housing (20) from moving into the passenger compartment (10).

[0205] The air conditioning system (2) according to the ninth aspect further includes a heater (6) and a control unit (8) in any one of the first to fifth aspects. The heater (6) is disposed at a position downstream of the evaporator (5) in the first direction. The control unit (8) performs drive control of the air conditioning system (2). The control unit (8) is configured to be able to execute a drying mode, in which the heater (6) is operated and the blower (4) is operated to generate a flow of air in the second direction, which is opposite to the first direction, to dry the evaporator (5).

[0206] According to this method, the evaporator (5) can be exposed to warm air, so that the evaporator (5) can be dried well.

[0207] The air conditioning system (2) according to the tenth aspect further includes a control unit (8), a heater (6), and a second-direction blower (4a) in any one of the first to fifth aspects.

The control unit (8) is configured to be able to execute a drying mode, in which the heater (6) is operated, the blower (4) is not operated, and the second-direction blower (4a) is operated to dry the evaporator (5).

[0208] According to this method, even when the blower (4) is not configured to be able to generate a flow of air in the reverse direction (second direction), the evaporator (5) can be exposed to warm air, so that the evaporator (5) can be dried well.

[0209] The air conditioning system (2) according to the eleventh mode is such that, in the eighth mode, it further includes an air duct (D3), a vehicle compartment side duct (D2), and a vehicle compartment side valve (27). The air duct (D3) is arranged at a position downstream of the evaporator (5) in the first direction and connects the interior of the vehicle compartment (10) to the housing (20). The vehicle compartment side duct (D2) connects the air duct (D3) to the functional substance generating device (3). The vehicle compartment side valve (27) opens and closes the flow path of the vehicle compartment side duct (D2). The control unit (8) opens the vehicle compartment side valve (27) and operates the blower (4) to generate a flow of air in a second direction, which is the direction opposite to the first direction.

[0210] According to this mode, by generating a flow of air in the second direction, it is possible to, for example, sterilize the filter (7) while delivering the functional substance into the vehicle compartment (10).

[0211] The air conditioning system (2) according to the twelfth mode is such that, in any one of the first to fifth modes, it further includes a control unit (8). The control unit (8) performs drive control of the air conditioning system (2). The control unit (8) is configured to be able to execute an exposure mode, in which the blower (4) is operated so that air is output from the blower (4) at a first air pressure to expose the evaporator (5) to the functional substance. After executing the exposure mode, the control unit (8) executes at least one of a drying mode and a filling mode. In the drying mode, the blower (4) is operated so that air is output from the blower (4) at a second air pressure higher than the first air pressure to dry the evaporator (5). In the filling mode, the housing (20) is filled with the functional substance.

[0212] According to this mode, after sterilizing the evaporator (5) in the exposure mode, further drying the evaporator (5) or sterilizing the evaporator (5) can achieve better sterilization of the evaporator (5).

[0213] The air-conditioning system (2) according to the thirteenth mode further includes an air duct (D3), a vehicle-side duct (D2), an air duct valve (28), a vehicle-side valve (27), and a control unit (8) in any one of the first to fifth modes. The air duct (D3) is arranged at a position downstream of the evaporator (5) in the first direction and connects the interior of the vehicle compartment (10) to the housing (20). The vehicle-side duct (D2) connects the air duct (D3) to the functional substance generating device (3). The air duct valve (28) opens and closes the flow path of the air duct (D3). The vehicle-side valve (27) opens and closes the flow path of the vehicle-side duct (D2). The control unit (8) performs drive control of the air-conditioning system (2).

[0214] According to this mode, after disinfecting the evaporator (5) in the exposure mode, the evaporator (5) is dried, and further disinfected, so that the disinfection of the evaporator (5) can be performed better.

[0215] The structures other than the first mode are not essential structures of the air-conditioning system (2) and can be appropriately omitted.
