[0024] An ion air supply device involved in one embodiment of the present disclosure is arranged at the top of the interior of a vehicle, and the ion air supply device includes: an ion generator that generates ions; a blower that blows air containing the ions into the interior of the vehicle; and a control unit. When the temperature in the interior of the vehicle is within a specified range, the control unit controls the blower to blow the air preferentially toward the seat side of the interior of the vehicle, and when the temperature is not within the specified range, the control unit controls the blower to blow the air toward a position closer to the top side than the seat side of the interior of the vehicle.

[0025] Thus, if the indoor temperature is such that the passenger may feel uncomfortable if the air containing ions is blown toward the seat side, the air containing ions can be blown toward the ceiling side, thereby efficiently supplying ions to the vehicle interior while suppressing discomfort for the passenger. Furthermore, if the indoor temperature is such that the passenger will not feel uncomfortable even if the air containing ions is blown toward the seat side, the air containing ions can be blown toward the seat side, thereby efficiently supplying ions to the vehicle interior while suppressing discomfort for the passenger.

[0026] In the ion air blowing device according to one aspect of the present disclosure, the control unit may determine a direction in which the air is blown based on whether or not there are passengers in each seat in the vehicle, and control the air blower to blow the air in the determined direction.

[0027] Thus, the air containing ions can be blown toward the seat side where the passenger is seated, and thus ions can be supplied more efficiently into the interior of the vehicle while suppressing discomfort to the passenger.

[0028] Furthermore, the ion blower according to one embodiment of the present disclosure may be disposed at a position different from the air conditioner of the vehicle.

[0029] This allows air containing ions to be blown even to locations that cannot be reached by air blown from the air conditioner, and thus allows ions to be supplied to the interior of the vehicle more efficiently.

[0030] In addition, in the ion air supply device involved in one embodiment of the present disclosure, when the air conditioner of the vehicle is in the external air introduction mode, the control unit may control the blower not to blow the air, and when the air conditioner of the vehicle is in the internal air circulation mode, the control unit may control the blower to blow the air.

[0031] This prevents the air from being blown when in the external air intake mode, which is more likely to discharge ions to the outside of the vehicle than in the internal air circulation mode. Furthermore, in the internal air circulation mode, which is less likely to discharge ions to the outside of the vehicle than in the external air intake mode, the air containing ions can be blown. This allows for more efficient ion supply to the interior of the vehicle.

[0032] In addition, in the ion air supply device involved in one embodiment of the present disclosure, the control unit may control the blower in such a manner that the volume of the air blown when the air conditioner of the vehicle is in the external air introduction mode is greater than the volume of the air blown when the air conditioner of the vehicle is in the internal air circulation mode.

[0033] Thus, in the external air intake mode, which is more likely to discharge ions to the exterior of the vehicle than in the internal air circulation mode, the air volume can be increased compared to the internal air circulation mode, thereby suppressing a decrease in the indoor ion concentration. Furthermore, in the internal air circulation mode, which is less likely to discharge ions to the exterior of the vehicle than in the external air intake mode, the air volume can be reduced compared to the external air intake mode, thereby suppressing power consumption, etc. Thus, ions can be supplied to the interior of the vehicle more efficiently.

[0034] In the ion air blowing device according to one embodiment of the present disclosure, the control unit may determine the air volume of the blown air based on the air volume of the air conditioner of the vehicle, and control the blower to blow the air at the determined air volume.

[0035] As a result, the air volume of the air containing ions can be increased or decreased based on the air volume of the air conditioner, so that ions can be supplied to the interior of the vehicle more efficiently.

[0036] Furthermore, in the ion blower according to one aspect of the present disclosure, the control unit may set the air conditioner of the vehicle to an outside air introduction mode when the wipers of the vehicle are on.

[0037] This allows the wipers to be turned on when there is a high probability of rain, in which case the outside air intake mode can be selected. This allows moisture outside the vehicle to be easily drawn into the vehicle's interior, creating a humid environment where ions are more easily generated. Consequently, ions can be more efficiently supplied to the vehicle's interior.

[0038] In addition, in the ion air supply device involved in one embodiment of the present disclosure, the control unit may control the air supply fan so that the air volume blown after a prescribed period of time from the start of blowing the air toward the seat side in the room is smaller than the air volume blown before the prescribed period of time from the start of blowing the air toward the seat side in the room when controlling the air supply fan to blow the air preferentially toward the seat side in the room.

[0039] Thus, before the predetermined period has passed, the air volume is increased compared to after the predetermined period has passed, thereby supplying more ions than after the predetermined period has passed. Furthermore, after the predetermined period has passed, the air volume is reduced compared to before the predetermined period has passed, thereby reducing power consumption, etc., compared to before the predetermined period has passed. Thus, ions can be supplied to the interior of the vehicle more efficiently.

[0040] In addition, the ion air supply device involved in one embodiment of the present disclosure may also be provided with a control selection receiving unit, which receives a selection as to whether the control unit controls the air blower in such a manner that the volume of the air blown after the prescribed period is smaller than the volume of the air blown before the prescribed period.

[0041] This allows selection of whether to control the blower so that the air volume blown after the predetermined period is smaller than the air volume blown before the predetermined period, depending on the vehicle state, etc., thereby more efficiently supplying ions to the interior of the vehicle.

[0042] Furthermore, the ion blower according to one aspect of the present disclosure may further include a generation selection accepting unit that accepts a selection as to whether or not to cause the ion generator to generate the ions.

[0043] This makes it possible to select whether or not to cause the ion generator to generate ions according to the state of the vehicle, etc., thereby preventing wasteful generation of ions, etc.

[0044] Hereinafter, embodiments will be described in detail with reference to the accompanying drawings.

[0045] In addition, the embodiments described below all represent general or specific examples. The numerical values, shapes, materials, constituent elements, configuration positions of constituent elements, and connection methods, steps, and the order of steps shown in the following embodiments are examples and are not intended to limit the present disclosure. In addition, the constituent elements in the following embodiments that are not recorded in the independent claims are described as arbitrary constituent elements. In addition, each figure is a schematic diagram and may not be strictly illustrated. In addition, in each figure, the same structural components are marked with the same symbols.

[0046] (Implementation Method)

[0047] Figure 1 This is a schematic diagram of a vehicle 1 on which the ion blower 10 according to the embodiment is installed, viewed from above. Figure 2 Observed from the left side Figure 1 Schematic diagram of the interior 2 of the vehicle 1. Figure 3 When viewed from the left side of the vehicle 1 Figure 1 The schematic diagram of the ion air supply device 10 is obtained. Figure 3 In FIG, the top 3 of the interior 2 is shown in cross section. Figure 4 The vehicle 1 is viewed from the bottom side. Figure 1 Schematic diagram of the ion air supply device 10 obtained. Figures 1 to 4 The structure and the like of the ion blowing device 10 will be described.

[0048] like Figure 1 and Figure 2 As shown, the vehicle 1 has seats in a cabin 2. In this embodiment, the vehicle 1 has a driver's seat 4a, a passenger seat 4b, a right rear seat 4c, and a left rear seat 4d as seats.

[0049] The ion blowing device 10 blows air A containing ions (see Figure 3 and Figure 4 ) device. The ion air supply device 10 is arranged on the top 3 of the interior 2. In this embodiment, the ion air supply device 10 is set on the high-position instrument panel, in the front and rear direction of the vehicle 1 ( Figure 1 In the X-axis direction of the same) it is located in front of the driver's seat 4a and the passenger seat 4b ( Figure 1 The position of the vehicle 1 in the left and right directions ( Figure 1 The ion blower 10 can blow air A toward the front seats (driver's seat 4a and passenger seat 4b) (see Figure 2 Arrow A1), or blow air A toward the rear seats (right rear seat 4c and left rear seat 4d) (refer to Figure 2 Arrow A2), or blow air A toward the top 3 side from the seat side (refer to Figure 2 The arrow A3) will be described in detail later.

[0050] like Figure 3 and Figure 4 As shown, the ion blowing device 10 includes an ion generator 11 and a blower 12. The blower 12 includes a motor 13.

[0051] The ion generator 11 generates ions. For example, the ion generator 11 generates ions by applying a high voltage to moisture in the air.

[0052] The blower 12 blows air A containing ions generated by the ion generator 11 into the room 2. The blower 12 can blow air A toward the seat side or toward a position closer to the top 3 than the seat side. Specifically, the blower 12 can blow air A toward the front seat side (driver's seat 4a and passenger seat 4b) (see Figure 2 Arrow A1), or blow air A toward the rear seats (right rear seat 4c and left rear seat 4d) (refer to Figure 2 Arrow A2), or blow air A toward the top 3 side from the seat side (refer to Figure 2 In this embodiment, the blower 12 can move in the vertical direction of the vehicle 1 ( Figure 1 The larger the opening angle B is, the lower side (the Z axis direction) can be opened and closed, and the blowing direction can be changed by opening and closing. Figure 1 The smaller the opening angle B is, the more it can be blown toward the upper side ( Figure 1 By turning off the blower 12, the air A can be prevented from being blown into the room 2.

[0053] The motor 13 opens and closes the air outlet of the blower 12. For example, when the motor 13 rotates to one side, the blower 12 rotates in the direction of opening the air outlet of the blower 12, and when the motor 13 rotates to the other side, the blower 12 rotates in the direction of closing the air outlet of the blower 12.

[0054] Figure 5 It shows Figure 1 10. Figure 5 The functional structure and the like of the ion blowing device 10 will be described.

[0055] like Figure 5 As shown, vehicle 1 further includes a detection unit 5 , an air conditioner 6 , and wipers 7 .

[0056] The detection unit 5 includes a temperature sensor 5a and an interior camera 5b. The temperature sensor 5a is a sensor for detecting the temperature of the interior 2. The temperature of the interior 2 is obtained by the temperature sensor 5a. The interior camera 5b is a camera for detecting whether there are passengers in each seat of the interior 2. The interior camera 5b images the interior 2 to determine whether there are passengers in the driver's seat 4a, the passenger seat 4b, the right rear seat 4c, and the left rear seat 4d. The interior camera 5b obtains the image of the interior 2. In addition, at least one of the temperature sensor 5a and the interior camera 5b may be built into the ion air supply device 10.

[0057] The air conditioner 6 has both heating and cooling functions. It can switch between an outside air intake mode and an internal air circulation mode. The outside air intake mode introduces air from outside the vehicle 1, i.e., outside air, into the interior 2. The internal air circulation mode, unlike the outside air intake mode, makes it less likely that outside air will be introduced into the interior 2, and instead circulates the air within the interior 2, i.e., the interior air. The air outlet of the air conditioner 6 is located on the dashboard and / or roof 3 of the vehicle 1, for example.

[0058] The wiper 7 wipes off rainwater or the like adhering to the front window (windshield) or rear window of the vehicle 1 .

[0059] The ion air supply device 10 is arranged at a different position from the air conditioner 6. That is, the position of the air outlet of the air blower 12, etc. is different from the position of the air outlet of the air conditioner 6, etc. The ion air supply device 10 does not have a heating function or a cooling function. The ion air supply device 10 also includes a generation selection button 14, a control selection button 15, and an ECU 16. The air blower 12 includes a right fan 12a and a left fan 12b. The right fan 12a blows air A toward a position on the right side of the center of the room 2 in the left-right direction of the vehicle 1. The left fan 12b blows air A toward a position on the left side of the center of the room 2 in the left-right direction of the vehicle 1.

[0060] The generation selection button 14 is an example of a generation selection receiving unit that receives a selection regarding whether or not to cause the ion generator 11 to generate ions. By pressing the generation selection button 14, the passenger can select whether or not to cause the ion generator 11 to generate ions. For example, if the generation selection button 14 is pressed while the ion generator 11 is selected to generate ions, the ion generator 11 is switched to a state where it is not generated. Alternatively, if the generation selection button 14 is pressed while the ion generator 11 is selected not to generate ions, the ion generator 11 is switched to a state where it is generated. If the ion generator 11 is selected to generate ions, the ion generator 11 generates ions. On the other hand, if the ion generator 11 is not selected to generate ions, the ion generator 11 does not generate ions.

[0061] The control selection button 15 is an example of a control selection accepting unit that accepts a selection of whether to have the ECU 16 control the blower 12 so that the volume of air A blown toward the seat side of the interior 2 after a predetermined period has elapsed since the start of blowing air A toward the seat side of the interior 2 is smaller than the volume of air A blown toward the seat side of the interior 2 before the predetermined period has elapsed. By pressing the control selection button 15, a passenger can select whether to have the ECU 16 control the blower 12 in this manner. For example, if the control selection button 15 is pressed while the control selection button 15 is pressed, the control is switched to a non-control state. Alternatively, if the control selection button 15 is pressed while the control selection button 15 is pressed while the control selection button 15 is pressed, the control is switched to a non-control state. If the control selection is pressed while the control selection button 15 is pressed, the control is switched to a non-control state. If the control selection is pressed while the control selection button 15 is pressed, the control is switched to a non-control state. If the control selection is pressed while the control selection button 15 is pressed, the control is switched to a non-control state. On the other hand, when a selection is made not to perform control in this manner, the ECU 16 controls the blower 12 in such a manner that the volume of air A blown after a prescribed period has passed since the air A was started to be blown toward the seat side of the room 2 is not smaller than the volume of air A blown before a prescribed period has passed since the air A was started to be blown toward the seat side of the room 2.

[0062] The ECU 16 is an example of a control unit that controls the blower 12. When the temperature of the room 2 is within a specified range, the ECU 16 controls the blower 12 to preferentially blow air A toward the seat side of the room 2. That is, when the temperature of the room 2 is within the specified range, the blower 12 preferentially blows air A toward the seat side of the room 2. In this embodiment, blowing toward the seat side includes blowing toward the front seat side (at least one of the driver's seat 4a and the passenger seat 4b) and blowing toward the rear seat side (at least one of the right rear seat 4c and the left rear seat 4d). Furthermore, preferentially blowing toward the seat side includes not only always blowing toward the seat side but also simultaneously blowing toward the seat side and blowing toward a position closer to the top 3 than the seat side, with blowing toward the seat side lasting longer than toward the top 3. Specifically, prioritizing blowing toward the seat side includes repeatedly alternating between blowing toward the seat side for a certain period and blowing toward the top 3 side of the seat side for a shorter period. Blowing toward the top 3 side of the seat side refers to blowing toward the side closer to the top 3 than toward the seat side. In the present embodiment, blowing toward the top 3 side of the seat side refers to blowing toward the top 3 side (above) of the rear seats (right rear seat 4c and left rear seat 4d). For example, the predetermined range is a normal temperature range, such as a temperature range where the occupant is less likely to feel uncomfortable if the blown air A hits them (for example, 20°C to 30°C). This predetermined range can be preset by the occupant or the like, or it can be stored in advance by the ECU 16.

[0063] When controlling the blower 12 to preferentially blow air A toward the seat, the ECU 16 controls the blower 12 so that the volume of air A blown after a predetermined period has elapsed since the start of blowing air A toward the seat is smaller than the volume of air A blown before the predetermined period has elapsed. Specifically, the blower 12 reduces the volume of air A blown after the predetermined period has elapsed since the start of blowing air A toward the seat, so that the volume of air A blown is smaller than the volume before the predetermined period has elapsed since the start of blowing air A toward the seat. For example, the predetermined period may be set in advance by a passenger or the like.

[0064] When the temperature of the room 2 is outside the specified range, the ECU 16 controls the blower 12 to blow air A toward a position closer to the ceiling 3 than the seat side of the room 2. That is, when the temperature of the room 2 is outside the specified range, the blower 12 blows air A toward a position closer to the ceiling 3 than the seat side of the room 2. In the present embodiment, when the temperature of the room 2 is outside the specified range, the ECU 16 controls the blower 12 to blow air A toward a position closer to the ceiling 3 than the rear seat side (the right rear seat 4 c and the left rear seat 4 d).

[0065] The ECU 16 determines the direction of air A based on whether or not each seat in the interior 2 is occupied, and controls the blower 12 to blow air A in the determined direction. The ECU 16 determines whether or not each seat is occupied based on images captured by the interior camera 5b. For example, the ECU 16 controls the blower 12 to blow air A toward the seat where the passenger is seated. For example, if a passenger is seated in the front seat (at least one of the driver's seat 4a and the passenger seat 4b) or the rear seat (at least one of the right rear seat 4c and the left rear seat 4d), the ECU 16 controls the blower 12 to alternately blow air toward the front seat and toward the rear seat.

[0066] For example, when blowing toward the driver's seat 4a or the right rear seat 4c, the ECU 16 controls the blower 12 so that the right fan 12a blows the air A. Furthermore, when blowing toward the passenger seat 4b or the left rear seat 4d, the ECU 16 controls the blower 12 so that the left fan 12b blows the air A.

[0067] When the air conditioner 6 is in the outside air introduction mode, the ECU 16 controls the blower 12 not to blow air A. When the air conditioner 6 is in the inside air circulation mode, the ECU 16 controls the blower 12 to blow air A. In other words, when the air conditioner 6 is in the outside air introduction mode, the air A is not blown into the room 2. When the air conditioner 6 is in the inside air circulation mode, the air A is blown into the room 2.

[0068] Furthermore, instead of controlling the blower 12 in this manner, the ECU 16 may control the blower 12 so that the volume of the air A blown when the air conditioner 6 is in the outside air intake mode is larger than the volume of the air A blown when the air conditioner 6 is in the inside air circulation mode. In other words, when the air conditioner 6 is in the outside air intake mode, the volume of the air A blown by the blower 12 may be increased compared to when the air conditioner 6 is in the inside air circulation mode.

[0069] When the air conditioner 6 is in the outside air introduction mode, whether or not the blower 12 blows the air A may be selectable by a passenger or the like, or may be set to only one of the two.

[0070] The ECU 16 determines the volume of the blown air A based on the air volume of the air conditioner 6 and controls the blower 12 to blow the determined volume of air A. For example, the ECU 16 controls the blower 12 so that the volume of the blown air A increases as the air volume of the air conditioner 6 increases.

[0071] When the wiper 7 is in the on state, the ECU 16 sets the air conditioner 6 to the outside air introduction mode.

[0072] Figure 6 It shows Figure 1 Flowchart of an example of the operation of the ion blower 10 controlling the blower 12 . Figure 7 It shows Figure 6 See the subsequent flowchart. Figure 6 and Figure 7 An example of the operation of the ion blower 10 controlling the blower 12 will be described.

[0073] Here, the following case is described: when the air conditioner 6 is in the outside air introduction mode, the ECU 16 controls the blower 12 to not blow air A, and when the air conditioner 6 is in the internal air circulation mode, the ECU 16 controls the blower 12 to blow air A. Furthermore, the following case is described: the generation selection button 14 is used to select the ion generator 11 to generate ions, and the control selection button 15 is used to select the ECU 16 to control the blower 12 so that the volume of air A blown toward the seat side of the room 2 after a predetermined period of time has passed since the start of blowing air A toward the seat side of the room 2 is smaller than the volume of air A blown toward the seat side of the room 2 before the predetermined period of time has passed since the start of blowing air A toward the seat side of the room 2.

[0074] like Figure 6 As shown, the ECU 16 determines whether the air conditioner 6 is on (step S1). For example, the ECU 16 determines that the air conditioner 6 is on when the switch of the air conditioner 6 is on, and determines that the air conditioner 6 is not on when the switch of the air conditioner 6 is off.

[0075] If the air conditioner 6 is on ("Yes" in step S1), the ECU 16 determines whether the air conditioner 6 is in the outside air intake mode (step S2). For example, the ECU 16 determines whether the air conditioner 6 is in the outside air intake mode based on a switch for switching between the outside air intake mode and the internal air circulation mode. If the air conditioner 6 is not in the outside air intake mode, it is in the internal air circulation mode.

[0076] When the air conditioner 6 is in the outside air introduction mode (YES in step S2 ), the ECU 16 turns off the ion generator 11 (step S3 ). If the ion generator 11 is already off, the ECU 16 maintains the off state.

[0077] If the air conditioner 6 is not on ("No" in step S1), the ECU 16 turns on the ion generator 11 (step S4). If the air conditioner 6 is not in the outside air intake mode ("No" in step S2), the ECU 16 turns on the ion generator 11 (step S4). Furthermore, if the ion generator 11 is already on, the ECU 16 maintains the on state.

[0078] The ECU 16 obtains the temperature of the interior 2 of the vehicle 1 (step S5) and determines whether the temperature of the interior 2 of the vehicle 1 is within a prescribed range (step S6). The ECU 16 obtains the temperature of the interior 2 from the temperature sensor 5a and determines whether the temperature is within a prescribed range.

[0079] If the temperature of the interior 2 of the vehicle 1 is not within the prescribed range ("No" in step S6), the ECU 16 controls the blower 12 to blow the air A toward the roof 3 (step S7). Figure 2 Air A is blown in the direction indicated by arrow A3.

[0080] If the temperature in the interior 2 of the vehicle 1 is within the specified range ("YES" in step S6), the ECU 16 determines whether each seat is occupied (step S8) and determines the direction of the air A based on the occupancy of each seat (step S9). The ECU 16 obtains an image captured by the interior camera 5b and determines the occupancy of each seat based on the image. For example, if a passenger is seated in the driver's seat 4a, the ECU 16 determines to blow air A toward the driver's seat 4a. If a passenger is seated in the passenger seat 4b, the ECU 16 determines to blow air A toward the passenger seat 4b. If a passenger is seated in the right rear seat 4c, the ECU 16 determines to blow air A toward the right rear seat 4c. If a passenger is seated in the left rear seat 4d, the ECU 16 determines to blow air A toward the left rear seat 4d. When no passengers are seated in the seats, the ECU 16 determines to blow air A toward the front seats (driver's seat 4a and passenger seat 4b) and rear seats (right rear seat 4c and left rear seat 4d).

[0081] The ECU 16 controls the blower 12 to blow air A preferentially toward the seat side (step S10). The ECU 16 controls the blower 12 to blow air A in the direction determined in step S9. For example, if only the front seat of the front seat and the rear seat is occupied by a passenger, the ECU 16 determines to blow air toward the front seat side and controls the blower 12 to blow air toward the front seat side. Figure 2 The air A is blown alternately in the direction indicated by the arrow A1 and the direction indicated by the arrow A3. In this case, the ECU 16 controls the blower 12 to give priority to blowing in the direction indicated by the arrow A1 rather than in the direction indicated by the arrow A3. In addition, when only the rear seat of the front seat and the rear seat is occupied by a passenger, the ECU 16 determines to blow toward the rear seat side and controls the blower 12 to blow toward the rear seat side. Figure 2 In this case, the ECU 16 controls the blower 12 to give priority to blowing air in the direction indicated by the arrow A2 rather than the direction indicated by the arrow A3. In addition, when there are passengers sitting in the front seats and the rear seats, the ECU 16 decides to blow air toward the front seat side and the rear seat side, and controls the blower 12 to blow air in the direction indicated by the arrow A2 and the direction indicated by the arrow A3. Figure 2 The air A is blown alternately in the direction indicated by the arrow A1 and the direction indicated by the arrow A2. In this case, the ECU 16 may give priority to blowing in the direction indicated by the arrow A1 or the direction indicated by the arrow A2 over one of them, or may blow in both directions equally (for example, for the same period).

[0082] The ECU 16 obtains the air volume of the air conditioner 6 (step S11), determines the air volume of the blown air A based on the air volume of the air conditioner 6 (step S12), and controls the blower 12 to blow the air A at the determined air volume (step S13). For example, if the air volume of the air conditioner 6 can be switched between five levels, the ECU 16 determines the air volume of the blown air A so that the air volume of the blown air A increases in the higher the air volume level.

[0083] The ECU 16 determines whether the blower 12 is controlled so as to blow the air A preferentially toward the seat side (step S14 ). That is, the ECU 16 determines whether step S10 has been performed.

[0084] When the blower 12 is controlled so as to blow the air A preferentially toward the seat side (YES in step S14 ), the ECU 16 determines whether a predetermined period has elapsed since the start of blowing (step S15 ).

[0085] If the predetermined period has not elapsed since the start of the blowing (NO in step S15 ), the ECU 16 again determines whether the predetermined period has elapsed since the start of the blowing (step S15 ).

[0086] If the predetermined period has elapsed since the start of air blowing ("YES" in step S15), the ECU 16 controls the blower 12 to reduce the volume of the blown air A compared to before the predetermined period elapsed (step S16). For example, if air A was being blown at a certain volume immediately before the predetermined period, the ECU 16 controls the blower 12 to blow air A at a volume smaller than the predetermined volume immediately after the predetermined period. The predetermined period can be set by the occupant, etc., as described above, or it can be pre-set by the ECU 16, for example, as the period during which the air A becomes effective for the occupant upon initial boarding (e.g., 5 minutes).

[0087] For example, the ECU 16 repeatedly performs Figure 6 and Figure 7 The operation shown is as follows. Furthermore, for example, if the ion generator 11 is not selected for ion generation via the generation selection button 14, the ECU 16 does not perform steps S1 to S4, and the ion generator 11 is turned off. Consequently, instead of the ion-containing air A, air without ions is blown into the room 2. Furthermore, if the control selection button 15 is selected to not cause the ECU 16 to control the blower 12 so that the volume of air A blown toward the seat side of the room 2 after a predetermined period has elapsed, is smaller than the volume of air A blown toward the seat side of the room 2 before the predetermined period has elapsed—that is, if the ECU 16 is selected to control the blower 12 so that the volume of air A blown toward the seat side of the room 2 after a predetermined period has elapsed, is not smaller than the volume of air A blown toward the seat side of the room 2 before the predetermined period has elapsed—the ECU 16 does not perform steps S14 to S16.

[0088] Figure 8 It shows Figure 1 Flowchart of another example of the operation of the ion blower 10 controlling the blower 12 . Figure 9 It shows Figure 8 See the subsequent flowchart. Figure 8 and Figure 9 Another example of the operation of the ion blower 10 controlling the blower 12 will be described.

[0089] Here, the following case is described: ECU 16 controls blower 12 so that the volume of air A blown when air conditioner 6 is in outside air introduction mode is larger than the volume of air A blown when air conditioner 6 is in internal air circulation mode. Furthermore, the following case is described: ion generator 11 is selected to generate ions using generation selection button 14, and ECU 16 is selected to control blower 12 so that the volume of air A blown after a predetermined period of time has elapsed from the start of blowing air A toward the seat side of room 2 is smaller than the volume of air A blown before the predetermined period of time has elapsed from the start of blowing air A toward the seat side of room 2.

[0090] like Figure 8 and Figure 9 As shown, Figure 6 and Figure 7 The main difference in the operation shown is that the ECU 16 does not perform steps S1 to S3, but performs steps S21 to S25 instead of steps S11 to S13. Figure 6 and Figure 7 The following description will focus on the differences in the operations shown.

[0091] After controlling the blower 12 to blow the air A (step S7 or S10 ), the ECU 16 determines whether the air conditioner 6 is in the ON state (step S21 ).

[0092] When the air conditioner 6 is on (YES in step S21 ), the ECU 16 obtains the air volume of the air conditioner 6 (step S22 ), and determines whether the air conditioner 6 is in the outside air introduction mode (step S23 ).

[0093] If the air conditioner 6 is not on ("No" in step S21), the ECU 16 determines the volume of the blown air A so that the volume of the blown air A is smaller than the volume of the blown air A in the outside air intake mode (step S24). Furthermore, if the air conditioner 6 is not in the outside air intake mode ("No" in step S23), the ECU 16 determines the volume of the blown air A so that the volume of the blown air A is smaller than the volume of the blown air A in the outside air intake mode (step S24). In other words, the ECU 16 determines the volume of the blown air A so that the volume of the blown air A when the air conditioner 6 is not on (is off) is smaller than the volume of the blown air A when the air conditioner 6 is in the outside air intake mode. Furthermore, the ECU 16 determines the volume of the blown air A so that the volume of the blown air A when the air conditioner 6 is in the inside air circulation mode is smaller than the volume of the blown air A when the air conditioner 6 is in the outside air intake mode. For example, when the air volume of the air conditioner 6 can be switched among five stages, the ECU 16 determines the air volume of the blown air A so that the air volume of the blown air A decreases in the stages where the air volume decreases.

[0094] If the air conditioner 6 is in the outside air intake mode ("YES" in step S23), the ECU 16 determines the air volume of the blown air A so that the air volume of the blown air A is greater than the air volume of the blown air A in the internal air circulation mode (step S25). In other words, the ECU 16 determines the air volume of the blown air A so that the air volume of the blown air A is greater when the air conditioner 6 is in the outside air intake mode than when the air conditioner 6 is in the internal air circulation mode. For example, if the air volume of the air conditioner 6 can be switched between five levels, the ECU 16 determines the air volume of the blown air A so that the air volume of the blown air A is greater in the higher air volume levels.

[0095] The ECU 16 controls the blower 12 to blow the air A at the determined air volume (step S13 ).

[0096] For example, the ECU 16 repeatedly performs Figure 8 and Figure 9The operation shown is as follows. Furthermore, for example, if the ion generator 11 is not selected to generate ions using the generation selection button 14, the ECU 16 does not proceed to step S4, and the ion generator 11 is turned off. Thus, instead of the ion-containing air A, air containing no ions is blown into the room 2. Furthermore, if the control selection button 15 is selected not to have the ECU 16 control the blower 12 so that the volume of air A blown toward the seat side of the room 2 after a predetermined period has elapsed, is smaller than the volume of air A blown toward the seat side of the room 2 before the predetermined period has elapsed, that is, if the ECU 16 is selected to control the blower 12 so that the volume of air A blown toward the seat side of the room 2 after a predetermined period has elapsed, is not smaller than the volume of air A blown toward the seat side of the room 2 before the predetermined period has elapsed, the ECU 16 does not proceed to steps S14 through S16.

[0097] Figure 10 It shows Figure 1 Flowchart of an example of the operation of the ion air supply device 10 controlling the air conditioner 6. Figure 10 An example of the operation of the ion blower 10 controlling the air conditioner 6 will be described. Figure 10 The illustrated operation is performed when the wiper 7 is in the on state.

[0098] like Figure 10 As shown, the ECU 16 determines whether the air conditioner 6 is in the on state (step S31).

[0099] If the air conditioner 6 is not on (No in step S31 ), the ECU 16 turns on the air conditioner 6 (step S32 ). For example, the ECU 16 turns on the air conditioner 6 by sending a control signal for turning on the air conditioner 6 to the air conditioner 6 .

[0100] If the air conditioner 6 is on ("Yes" in step S31), the ECU 16 determines whether the air conditioner 6 is in the outside air introduction mode (step S33). If the air conditioner 6 is on (step S32), the ECU 16 determines whether the air conditioner 6 is in the outside air introduction mode (step S33).

[0101] If the air conditioner 6 is not in the outside air introduction mode ("No" in step S33), the ECU 16 switches the air conditioner 6 to the outside air introduction mode (step S34). For example, the ECU 16 switches the air conditioner 6 to the outside air introduction mode by sending a control signal to the air conditioner 6 for switching to the outside air introduction mode.

[0102] If the air conditioner 6 is in the outside air intake mode ("YES" in step S33), the ECU 16 determines whether the first period has elapsed (step S35). Furthermore, if the air conditioner 6 is switched to the outside air intake mode (step S34), the ECU 16 determines whether the first period has elapsed (step S35). For example, the first period is pre-set by the vehicle occupant or the like.

[0103] When the first period has not elapsed (No in step S35 ), the ECU 16 determines again whether the first period has elapsed (step S35 ).

[0104] If the first period has elapsed ("YES" in step S35), the ECU 16 switches the air conditioner 6 to the internal air circulation mode (step S36). For example, the ECU 16 switches the air conditioner 6 to the internal air circulation mode by sending a control signal to the air conditioner 6 for switching to the internal air circulation mode.

[0105] The ECU 16 determines whether the second period has elapsed (step S37). For example, the second period is set in advance by the passenger, etc. The second period may be longer or shorter than the first period, or may be the same as the first period.

[0106] When the second period has not elapsed (No in step S37 ), the ECU 16 determines again whether the second period has elapsed (step S37 ).

[0107] When the second period has elapsed (YES in step S37 ), the ECU 16 switches the air conditioner 6 to the outside air introduction mode (step S34 ).

[0108] As described above, the ECU 16 periodically switches the air conditioner 6 between the outside air introduction mode and the inside air circulation mode while the wiper 7 is in the on state.

[0109] The ion air supply device 10 involved in this embodiment is arranged at the top 3 of the interior 2 of the vehicle 1, and the ion air supply device includes: an ion generator 11, which generates ions; a blower 12, which blows air A containing ions into the interior 2; and an ECU 16. When the temperature of the interior 2 is within a specified range, the ECU 16 controls the blower 12 to blow the air A preferentially toward the seat side of the interior 2. When the temperature is not within the specified range, the ECU 16 controls the blower 12 to blow the air A toward a position closer to the top 3 side than the seat side of the interior 2.

[0110] Thus, when the temperature of the interior 2 is such that the passenger may feel uncomfortable if the air A containing ions is blown toward the seat side, the air A containing ions can be blown toward the ceiling 3 side, thereby efficiently supplying ions to the interior 2 of the vehicle 1 while suppressing discomfort for the passenger. Furthermore, when the temperature of the interior 2 is such that the passenger would not feel uncomfortable even if the air A containing ions is blown toward the seat side, the air A containing ions can be blown toward the seat side, thereby efficiently supplying ions to the interior 2 of the vehicle 1 while suppressing discomfort for the passenger.

[0111] In the ion blower 10 according to this embodiment, the ECU 16 determines the direction of the blown air A based on whether or not there are passengers in each seat in the interior 2 and controls the blower 12 to blow the air A in the determined direction.

[0112] As a result, the air A containing ions can be blown toward the seat side where the passenger is seated, and thus ions can be supplied more efficiently to the interior 2 of the vehicle 1 while suppressing discomfort to the passenger.

[0113] Furthermore, the ion blower 10 according to the present embodiment is arranged at a position different from the air conditioner 6 of the vehicle 1 .

[0114] This allows the air A containing ions to be blown even to locations that cannot be reached by the air blown from the air conditioner 6 , and thus allows the ions to be supplied to the interior 2 of the vehicle 1 more efficiently.

[0115] In addition, in the ion air supply device 10 involved in this embodiment, when the air conditioner 6 of the vehicle 1 is in the external air introduction mode, the ECU 16 controls the blower 12 not to blow air A, and when the air conditioner 6 of the vehicle 1 is in the internal air circulation mode, the ECU 16 controls the blower 12 to blow air A.

[0116] Thus, in the outside air introduction mode, which is more likely to discharge ions to the outside of the vehicle 1 than in the inside air circulation mode, it is possible to prevent the air A containing ions from being blown. Furthermore, in the inside air circulation mode, which is less likely to discharge ions to the outside of the vehicle 1 than in the outside air introduction mode, it is possible to blow the air A containing ions. Thus, ions can be supplied to the interior 2 of the vehicle 1 more efficiently.

[0117] In addition, in the ion air supply device 10 involved in this embodiment, the ECU 16 controls the blower 12 in such a manner that the air volume of the air A blown when the air conditioner 6 of the vehicle 1 is in the external air introduction mode is greater than the air volume of the air A blown when the air conditioner 6 of the vehicle 1 is in the internal air circulation mode.

[0118] Thus, in the outside air intake mode, which is more likely to discharge ions to the exterior of the vehicle 1 than in the inside air circulation mode, the air volume can be increased compared to the inside air circulation mode, thereby suppressing a decrease in the ion concentration in the interior 2. Furthermore, in the inside air circulation mode, which is less likely to discharge ions to the exterior of the vehicle 1 than in the outside air intake mode, the air volume can be reduced compared to the outside air intake mode, thereby suppressing power consumption, etc. Consequently, ions can be more efficiently supplied to the interior 2 of the vehicle 1.

[0119] In the ion blower 10 according to this embodiment, the ECU 16 determines the volume of the blown air A based on the air volume of the air conditioner 6 of the vehicle 1 and controls the blower 12 to blow the air A at the determined volume.

[0120] Thus, the air volume of the air A containing ions can be increased or decreased based on the air volume of the air conditioner 6 , so that ions can be supplied to the interior 2 of the vehicle 1 more efficiently.

[0121] Furthermore, in the ion blower 10 according to the present embodiment, the ECU 16 sets the air conditioner 6 of the vehicle 1 to the outside air introduction mode when the wipers 7 of the vehicle 1 are in the on state.

[0122] Thus, when wipers 7 are turned on, which is likely due to rain, the outside air intake mode can be set. This facilitates the intake of moisture from outside the vehicle 1 into the interior 2 of the vehicle 1, creating a humid environment in which ions are easily generated. Consequently, ions can be more efficiently supplied to the interior 2 of the vehicle 1.

[0123] In addition, in the ion air supply device 10 involved in this embodiment, when the ECU 16 controls the air blower 12 to blow air A preferentially toward the seat side of the room 2, the air volume of the air A blown after a prescribed period of time from the start of blowing the air A toward the seat side of the room 2 is smaller than the air volume of the air A blown before the prescribed period of time from the start of blowing the air A toward the seat side of the room 2.

[0124] Thus, before the predetermined period has passed, the air volume is increased compared to after the predetermined period has passed, thereby supplying more ions than after the predetermined period has passed. Furthermore, after the predetermined period has passed, the air volume is reduced compared to before the predetermined period has passed, thereby reducing power consumption, etc., compared to before the predetermined period has passed. Consequently, ions can be supplied to the interior 2 of the vehicle 1 more efficiently.

[0125] In addition, the ion air supply device 10 involved in this embodiment has a control selection button 15, which accepts a selection as to whether to allow the ECU 16 to control the air blower 12 in such a manner that the air volume of the air A blown after the specified period is smaller than the air volume of the air A blown before the specified period.

[0126] Thus, it is possible to select whether to control the blower 12 so that the volume of the air A blown after the predetermined period is smaller than the volume of the air A blown before the predetermined period, depending on the state of the vehicle 1, thereby more efficiently supplying ions to the interior 2 of the vehicle 1.

[0127] Furthermore, the ion blowing device 10 according to the present embodiment includes a generation selection button 14 for accepting a selection as to whether or not to cause the ion generator 11 to generate ions.

[0128] This makes it possible to select whether or not to cause the ion generator 11 to generate ions according to the state of the vehicle 1 , etc., and thus to suppress wasteful generation of ions, etc.

[0129] (Other embodiments, etc.)

[0130] The above description is based on the embodiment of one or more embodiments of the ion air supply device, but the present disclosure is not limited to the embodiment. Alternatively, as long as it does not depart from the main purpose of the present disclosure, the various modifications that can be obtained by those skilled in the art to the present embodiment are also included in the scope of the present disclosure.

[0131] In the above-mentioned embodiment, the case where the ECU 16 determines the direction of blowing air A based on whether there are passengers in each seat has been described, but it is not limited to this. The control unit may also determine the direction of blowing air containing ions based on whether there are passengers in each seat. For example, the control unit may control the blower to repeatedly and alternately blow air containing ions toward the front seats (driver's seat and co-pilot seat) and toward the rear seats (right rear seat and left rear seat) when the temperature in the vehicle's interior is within a specified range. In addition, in the case where there are no rear seats but there are a driver's seat and a co-pilot seat, the control unit may control the blower to repeatedly and alternately blow air containing ions toward the seats (driver's seat and co-pilot seat) and toward a position closer to the top side than the seats (driver's seat and co-pilot seat) when the temperature in the vehicle's interior is within a specified range.

[0132] In addition, in the above-mentioned embodiment, the case where the air blower 12 has the right fan 12a and the left fan 12b is described, but it is not limited to this. The air blower may also have one fan instead of multiple fans. In this case, for example, the control unit may also blow the air containing ions toward the front seats (driving seat and co-pilot seat) by blowing the air containing ions between the driving seat and the co-pilot seat. Similarly, the control unit may also blow the air containing ions toward the rear seats (right rear seat and left rear seat) by blowing the air containing ions between the right rear seat and the left rear seat. In addition, the fan can be rotated in the left and right directions, and a mechanism for changing the air supply direction of the fan can also be provided.

[0133] Furthermore, in the above-described embodiment, the ECU 16 determines the volume of the blown air A based on the air volume of the air conditioner 6, but the present invention is not limited to this. The control unit may also determine the volume of the blown air containing ions based on a method other than the air volume of the air conditioner. For example, the control unit may control the blower to blow the ion-containing air at a predetermined fixed volume regardless of the air volume of the air conditioner. Furthermore, for example, the control unit may control the blower so that the volume of the blown air containing ions varies between the seat side and the ceiling side.
