More specifically, the first sterilization device 51 of the present embodiment is provided on the ceiling 11 of the vehicle 1, for example, as shown in FIG. The installation location of the first sterilizing device 51 is not limited to this, and is provided in the vicinity of the pillar, the air outlet 60 of the car air conditioner 6, or the console box between the driver's seat and the passenger's seat. May be.

The first sterilization device 51 is an example of a spray unit in this embodiment. It should be noted that not the entire first sterilization device 51 but only the air outlet may be used as an example of the spray unit.

The second sterilizing device 52 irradiates the inside of the vehicle interior 20 with ultraviolet rays. Specifically, the ultraviolet rays emitted by the second sterilizing device 52 are UV-C.

FIG. 3 is a diagram showing an example of the appearance of the second sterilizing device 52 according to the first embodiment. The second sterilization device 52 includes a xenon flash lamp 520 and a main body portion 521. The xenon flash lamp 520 emits a flash containing UV-C.

The second sterilization device 52 is an example of the ultraviolet irradiation unit in the present embodiment. It should be noted that the xenon flash lamp 520, the LED, or the ultraviolet lamp portion may be used as an example of the ultraviolet irradiation unit instead of the entire second sterilization device 52.

The second sterilizing device 52 is provided, for example, in the door pocket or the lower part of the seat 4. Further, it is preferable that the second sterilizing device 52 irradiates a place where the passenger's hand easily touches or a place where a virus or a bacterium in the air easily accumulates with ultraviolet rays. A place that is easily touched by the passenger is, for example, a doorknob. Alternatively, a place where viruses or bacteria in the air are likely to accumulate is, for example, a floor.

Further, the light 72 is provided near the window 12 of the vehicle 1 or near the installation location of the second sterilizing device 52. The light 72 may be included in the configuration of the second sterilization device 52. The light 72 emits visible light while the second sterilizer 52 is irradiating with ultraviolet light.

The third sterilizing device 53 is an example of an air purifying device that purifies the air in the vehicle interior 20. FIG. 4 is a diagram showing an example of the appearance of the third sterilizing device 53 according to the first embodiment. As shown in FIG. 4, the third sterilization device 53 includes a main body portion 531 and a connection portion 530. The connection unit 530 is connected to, for example, a secondary battery such as a battery, and supplies electric power to the main body unit 531. Further, the connection unit 530 may also serve as a cable for wired connection with a vehicle control device or the like described later.

Further, FIG. 5 is an example of an exploded view of the third sterilizing device 53 according to the first embodiment. The main body 531 of the third sterilizer 53 includes an intake port 531a, a fan 531b, a filter 531c, an exhaust section 531d, and a belt 531e. The belt 531e is a fixative capable of fixing the third sterilizing device 53 to, for example, the headrest of the seat 4.

In FIG. 5, the fan 531b is not exposed due to the cover covering the fan 531b. The third sterilization device 53 purifies the air sucked from the intake port 531a by the filter 531c and discharges it from the exhaust unit 531d. A xenon flash lamp, LED, or ultraviolet lamp that irradiates the sucked air with UV-C or the like may be provided inside the third sterilizing device 53 such as the filter 531c. Further, the third sterilizer 53 may add charged particles to the air purified by the filter 531c and then discharge the charged particles. The air in the vehicle interior 20 is circulated by the third sterilizing device 53 and is gradually sterilized. The xenon flash lamp, the LED or the ultraviolet lamp, and the charged particle generator that irradiate the filter 531c, UV-C, etc. included in the third sterilizer 53 are examples of the air purifying unit in the present embodiment.

The configuration of the third sterilizer 53 is not limited to this, and any sterilizer that is harmless to the human body and can be used in a manned environment may be used. Further, in the example shown in FIG. 5, the third sterilizing device 53 has a built-in fan 531b, but the configuration may not include the fan 531b.

The vehicle 1 of the present embodiment sterilizes the inside of the vehicle compartment 20 by different sterilization means depending on the presence or absence of a person in the vehicle compartment 20. The length of time required for sterilization differs depending on the sterilization means. In addition, a means capable of sterilizing in a short time may be harmful to the human body, and it may be difficult to use it in a manned environment. On the other hand, a sterilizing means that is harmless to the human body and can be used in a manned environment may take a long time to sterilize.

For example, when hypochlorite water is used as the sterilizing solution, it may be usable in a manned environment if the concentration is sufficiently lower than the environmental standard, but the time required for sterilization becomes longer. Also, regarding the irradiation of ultraviolet rays, it may be possible to use it in a manned environment, such as using a special lamp having an emission spectrum with a limited emission wavelength or installing it in a place where it is not irradiated by people, but the irradiation intensity is high. The weaker it is and the farther it is from the irradiation position, the longer it takes to sterilize.

The first sterilization device 51 and the second sterilization device 52 of the present embodiment are sterilization means premised on use in an unmanned environment. Therefore, when the inside of the vehicle compartment 20 of the vehicle 1 is unmanned and the door of the vehicle 1 is closed, the first sterilizing device 51 and the second sterilizing device 52 operate.

Further, the second sterilizing device 52 further irradiates the ultraviolet rays when measures are taken to prevent the ultraviolet rays irradiated by the second sterilizing device 52 from leaking out of the irradiation range. In the present embodiment, the irradiation range of ultraviolet rays is inside the vehicle interior 20. As described above, the window glass 1200 of the vehicle 1 is an example of the shielding portion, and blocks the ultraviolet rays directed to the outside of the vehicle interior 20. When the window 12 is in the closed state, the ultraviolet rays leaking to the outside of the vehicle are reduced by the window glass 1200. The fact that the inside of the passenger compartment 20 is unmanned and that the window 12 is in a closed state are conditions for the second sterilizing device 52 to irradiate ultraviolet rays.

Further, the third sterilizing device 53 is a sterilizing means that is harmless to the human body and can be used in a manned environment. Therefore, in the present embodiment, when the user performs an operation instructing the start of sterilization, or when a person is absent in the vehicle interior 20, the first sterilization device 51 and the second sterilization device 51 and the second The sterilizing device 52 executes the sterilizing operation, and when a person is present in the vehicle interior 20, the third sterilizing device 53 executes the sterilizing operation.

Further, when the vehicle 1 is provided with a plurality of sterilizing means, the sterilizing operation is performed so that the sterilizing means do not interfere with each other's effects. For example, since the effect of hypochlorite water is reduced by ultraviolet rays, the second sterilizing device 52 does not irradiate the ultraviolet rays during the sterilizing operation of the first sterilizing device 51. In the present embodiment, after the first sterilizing device 51 sprays the sterilizing liquid into the vehicle interior 20, the second sterilizing device 52 irradiates the inside of the vehicle interior 20 with ultraviolet rays.

If there is time for the sterilizing liquid to vaporize before the passenger gets on board, the first sterilizing device 51 sterilizes after the second sterilizing device 52 irradiates the inside of the passenger compartment 20 with ultraviolet rays. The liquid may be sprayed into the vehicle interior 20. The case where the sterilizing liquid has time to vaporize before the passenger gets on the vehicle is, for example, when the user is separated from the vehicle 1 by a specified distance or more at the time when the user starts the sterilization before boarding. Or, when the user starts the sterilization after getting off the vehicle.

Although FIG. 1 shows an example in which the vehicle 1 is equipped with three types of sterilizing devices 5, the vehicle 1 does not have to be equipped with all of them. In the present embodiment, the vehicle 1 is provided with at least the first sterilizing device 51. The vehicle 1 may not be provided with the first sterilizing device 51, but may be provided with a sterilizing device 5 other than the first sterilizing device 51.

Further, the first sterilizing device 51 and the second sterilizing device 52 are operated by the electric power supplied from the secondary battery such as a battery. As a general rule, the first sterilizing device 51 and the second sterilizing device 52 are used when the inside of the vehicle is unmanned. Therefore, when the ignition power supply or the accessory power supply of the vehicle 1 is turned on, the power supply of the first sterilizing device 51 and the second sterilizing device 52 is turned off, and the ignition (IGN) power supply or the accessory (ACC) is turned on. Power is charged from the power source to the battery.

FIG. 6 is a diagram showing an example of circuit connection of the first sterilization device 51 according to the first embodiment. Note that FIG. 6 is omitted except for the configuration related to the power supply.

In the example shown in FIG. 6, the first sterilizing device 51 is connected to the power supply circuit of the audio device 905 mounted on the vehicle 1. In addition to the backup power supply 903b and the accessory power supply 902b, the audio device 905 is connected to the ignition power supply 901b from the ignition terminal of the key switch 906. The audio device 905 is connected to the ignition power supply 901a, the accessory power supply 902a, and the backup power supply 903a via the fuse box 904. Hereinafter, when the ignition power supplies 901a and 901b are not particularly distinguished, they are simply referred to as an ignition power supply 901. Further, when the

accessory power supplies

902a and 902b are not particularly distinguished, they are simply referred to as accessory power supplies 902. Further, when the

backup power supplies

903a and 903b are not particularly distinguished, they are simply referred to as backup power supplies 903.

Further, the constant power supply 907 is, for example, a power supply used for the door lock of the vehicle 1, and the ignition power supply of the vehicle 1 continues to be on even when the ignition power supply is off. The battery 908 supplies power to the constant power source 907 and the backup power source 903. The circuit connected to the battery 908 is provided with a fuse 909 and an alternator 910. It was

Further, the first sterilization device 51 is provided with a first switch (SW) 921, a second switch 922, a third switch 923, and a battery 924 used as a power source for the first sterilization device 51. Be done.

The first switch 921 is also called a charging switch, and is closed when the ignition power supply 901 or the accessory power supply 902 is on. Therefore, when the ignition power supply 901 or the accessory power supply 902 is on, the battery 924 is charged by the power supplied from the ignition power supply 901 or the accessory power supply 902. In the example shown in FIG. 6, the first switch 921 is connected to the ignition power supply 901, but may be connected to the accessory power supply 902.

The second switch 922, also called an unmanned determination switch, is closed when the specified conditions are met, and is open when the specified conditions are not met. When the second switch 922 is closed, power is supplied from the battery 924 to the load 925. The state in which power is being supplied from the battery 924 to the load 925 is said to be a state in which the power supply of the first sterilizing device 51 is on. The battery 924 is an example of a secondary battery that supplies electric power to the first sterilizing device 51 in the present embodiment. The battery 924 may be provided outside the first sterilization device 51.

The load 925 shown in FIG. 6 represents a configuration that consumes electric power contained in the first sterilization device 51, for example, an entire configuration that executes a sterilization operation such as spraying a mist-like sterilization liquid.

In the present embodiment, the sterilization operation is as follows: spraying a mist-like sterilizing liquid by the first sterilizing device 51, irradiating ultraviolet rays by the second sterilizing device 52, and air by the third sterilizing device 53. Represents cleanliness, etc.

The second switch 922 opens and closes under the control of the control unit of the first sterilizing device 51. The details of the control unit of the first sterilization device 51 will be described later.

The specified condition that the second switch 922 is closed in the present embodiment is also a condition that the control unit of the vehicle control device described later determines that the inside of the vehicle 1 is unmanned. The specified conditions are, for example, that the key of the vehicle 1 is in the off state, that is, the engine of the vehicle 1 is in the off state, the door of the vehicle 1 is locked, and the seating sensor 40 does not detect the seating of the occupant. That is. It should be noted that the content of the specified conditions is not limited to the conditions as long as it can be determined whether or not the inside of the vehicle 1 is unmanned. For example, the vehicle 1 may be provided with a motion sensor, an in-vehicle camera, a sound sensor, or the like in place of the seating sensor 40, or in addition to the seating sensor 40, and the detection results of these sensor devices are used as specified conditions. You may add it. Further, the degree of opening / closing of the window glass of each window 12 may be included in the specified conditions.

Further, the second switch 922 is opened after the execution of the sterilization operation of the first sterilization device 51 is completed. More specifically, after the execution of the sterilization operation of the first sterilization device 51 is completed, the completion notification is transmitted from the first sterilization device 51 to the sterilization completion notification device described later, and then the second switch. 922 is in the open state. As a result, the supply of electric power from the battery 924 to the load 925 is cut off.

The third switch 923 is provided between the battery 924 and the minus control line 926, and opens and closes in conjunction with the opening and closing of the door of the vehicle 1. The third switch 923 is closed when the door of the vehicle 1 is closed, and is open when the door of the vehicle 1 is open. When the power of the first sterilizing device 51 is on, the door of the vehicle 1 is locked so as not to be opened. Even if the door of the vehicle 1 is unlocked, when the door of the vehicle 1 is opened, the third switch 923 is opened, so that the power of the first sterilizing device 51 is turned off.

Next, the flow of the sterilization process executed by the in-vehicle sterilization system S1 configured as described above will be described.

FIG. 11 is a flowchart showing an example of the flow of the sterilization process according to the first embodiment. In FIG. 11, an example of sterilizing the inside of the passenger compartment 20 of the vehicle 1 after the passenger gets off the vehicle 1 will be described.

First, the control unit 100 of the vehicle control device 10 determines whether or not a signal instructing the start of sterilization has been received from the portable device 8 via the first communication unit 110 (S101). This process is executed, for example, by the passenger presence / absence determination unit 101.

If the signal instructing the start of sterilization has not been received from the portable device 8 (S101 "No"), the process of S101 is repeated.

Further, when a signal instructing the start of sterilization is received from the portable device 8 (S101 “Yes”), the passenger presence / absence determination unit 101 of the control unit 100 of the vehicle control device 10 is in the passenger compartment 20 of the vehicle 1. It is determined whether or not there is a person in (S102).

When the passenger presence / absence determination unit 101 determines that there is no person in the vehicle interior 20 (S102 “No”), the operation control unit 103 of the control unit 100 of the vehicle control device 10 is the first sterilization device 51. Turn on the power (S103).

In this case, the first sterilizing device 51 sprays the sterilizing liquid. Further, in this case, the light 71 irradiates the sprayed sterilizing liquid with light. One sterilization operation of the first sterilization device 51 is defined by, for example, the length of time or the amount of the sterilization liquid to be sprayed. The first sterilization device 51 continues to operate while the power is on until the sterilization operation for one time is completed (S104 "No").

Then, the first sterilization device 51 transmits a signal indicating the completion of sterilization to the sterilization completion notification device 50 when a specified length of time has elapsed or a specified amount of sterilization solution is sprayed. .. When the sterilization operation is completed (S104 "Yes"), the power supply of the first sterilization device 51 is turned off (S105). In this case, the light 71 ends the irradiation.

The device status determination unit 104 of the control unit 100 of the vehicle control device 10 receives a notification of the completion of sterilization by the first sterilization device 51 from the sterilization completion notification device 50. In this case, the device state determination unit 104 sends information indicating the completion of sterilization by the first sterilization device 51 to the window open / closed state determination unit 102.

Then, the control unit 100 of the vehicle control device 10 determines whether or not the ultraviolet leakage countermeasure of the vehicle 1 is effective (S106). Specifically, in the present embodiment, the window open / closed state determination unit 102 determines whether or not the window 12 of the vehicle 1 is in the closed state. When the window open / closed state determination unit 102 determines that the window 12 of the vehicle 1 is in the closed state, that is, when it is determined that the ultraviolet leakage countermeasure of the vehicle 1 is effective (S106 “Yes”), the operation command unit 103 Turns on the power of the second sterilizing device 52 (S107). In this case, the light 72 is turned on.

The second sterilization device 52 continues to operate while the power is on until the sterilization operation for one time is completed (S108 "No"). One sterilization operation of the second sterilization device 52 is defined by, for example, the length of the ultraviolet irradiation time.

Then, the second sterilization device 52 transmits a signal indicating the completion of sterilization to the sterilization completion notification device 50 when the specified length of time has elapsed. When the sterilization operation is completed (S108 “Yes”), the power supply of the second sterilization device 52 is turned off (S109). In this case, the light 72 ends lighting.

The device state determination unit 104 of the control unit 100 of the vehicle control device 10 receives a notification of the completion of sterilization by the second sterilization device 52 from the sterilization completion notification device 50. In this case, the device state determination unit 104 determines that the sterilization is completed (S110). In this case, returning to the process of S101, the control unit 100 of the vehicle control device 10 waits for the acceptance of the instruction to start the next sterilization.

Further, when the window open / closed state determination unit 102 determines that the window 12 of the vehicle 1 is in the open state, that is, when it is determined that the ultraviolet leakage countermeasure of the vehicle 1 is not effective (S106 “No”), the operation command The unit 103 does not turn on the power of the second sterilizing device 52, and proceeds to the process of S110. In this case, the irradiation of ultraviolet rays by the second sterilizing device 52 is not executed.

Further, when the passenger presence / absence determination unit 101 determines that a person exists in the passenger compartment 20 (S102 “Yes”), the operation command unit 103 turns on the power of the third sterilization device 53 (S111). ).

The third sterilization device 53 continues to operate while the power is on until the sterilization operation for one time is completed (S112 "No"). One sterilization operation of the third sterilization device 53 is defined by, for example, the length of operating time.

Then, the third sterilization device 53 transmits a signal indicating the completion of sterilization to the sterilization completion notification device 50 when the specified length of time has elapsed. When the sterilization operation is completed (S112 “Yes”), the power of the third sterilization device 53 is turned off (S113).

The device state determination unit 104 of the control unit 100 of the vehicle control device 10 receives a notification of the completion of sterilization by the second sterilization device 52 from the sterilization completion notification device 50. Also in this case, the device state determination unit 104 determines that the sterilization is completed (S110). Then, returning to the process of S101, the control unit 100 of the vehicle control device 10 waits for the acceptance of the instruction to start the next sterilization.

Since the third sterilizing device 53 can be used in a manned state, it may be always in operation while the vehicle 1 is in operation.

Further, when the vehicle 1 does not have the third sterilization device 53, if the passenger presence / absence determination unit 101 determines that there is a person in the vehicle compartment 20 in the process of S102, the sterilization of S101 is performed without sterilization. Return to processing. If the vehicle 1 does not have the second sterilization device 52, the process returns to the process of S101 when the sterilization by the first sterilization device 51 is completed.

Further, after the sterilization operation by the first sterilization device 51, the control unit 100 of the vehicle control device 10 opens the window 12 or controls the car air conditioner 6 to introduce air outside the vehicle to promote ventilation. May be executed. For example, the control unit 100 of the vehicle control device 10 controls the opening and closing of the window 12 by transmitting a control signal to the mechanism for controlling the opening and closing of the window glass 1200 via CAN or other lines. When the control unit 100 opens the window 12 for the purpose of ventilation, the window glass 1200 may be partially moved to the extent that a gap is formed in the window 12 instead of the fully open state.

As described above, according to the vehicle 1 of the present embodiment, the vehicle interior is provided with the first sterilizing device 51 provided outside the air outlet of the car air conditioner 6 and spraying the sterilizing liquid into the vehicle interior 20.

Further, the vehicle 1 of the present embodiment is further provided with a second sterilization device 52 that irradiates the inside of the vehicle interior 20 with ultraviolet rays, so that the effect of sterilization can be further enhanced.

Further, the vehicle 1 of the present embodiment is further provided with a third sterilizing device 53 that purifies the air in the vehicle interior 20, so that the vehicle interior 20 is not limited to an unmanned environment but is a manned environment. However, since sterilization can be performed, the effect of sterilization can be further enhanced.

Further, the vehicle 1 of the present embodiment sterilizes the inside of the vehicle compartment 20 by different sterilization means depending on the presence or absence of a person in the vehicle compartment 20. Therefore, according to the vehicle 1 of the present embodiment, the sterilizing means that can be used in the manned environment and the sterilizing means that cannot be used in the manned environment can be appropriately used depending on the presence or absence of passengers.

For example, the vehicle 1 of the present embodiment receives an operation instructing the start of sterilization by the user, and when a person is absent in the vehicle interior 20, the first sterilization device 51 is used. The sterilizing liquid is sprayed into the vehicle compartment 20, and when a person is present in the vehicle compartment 20, the third sterilizing device 53 purifies the air in the vehicle compartment 20. With such a function, according to the vehicle 1 of the present embodiment, when the user performs an operation instructing the start of sterilization, it is automatically appropriate without visually confirming the presence or absence of a person in the vehicle 1. Can be sterilized.

Further, in the vehicle 1 of the present embodiment, after the first sterilizing device 51 sprays the sterilizing liquid into the vehicle interior 20, the second sterilizing device 52 irradiates the inside of the vehicle interior 20 with ultraviolet rays. According to the vehicle 1 of the present embodiment, by not spraying the sterilizing liquid and irradiating with ultraviolet rays at the same time, for example, when hypochlorite water is used as the sterilizing liquid, the sterilization by the sterilizing liquid is completed. Avoid reducing the effectiveness of the disinfectant solution by UV light before. In addition, by spraying the disinfectant solution first, the time from the spraying of the disinfectant solution to the next boarding of the vehicle 1 is secured for a long time, and the sprayed disinfectant solution is boarded. It can be easily vaporized by the time a person gets on board.

Further, the vehicle 1 of the present embodiment includes a window glass 1200 that blocks ultraviolet rays toward the outside of the vehicle interior 20, and when the window glass 1200 blocks ultraviolet rays toward the outside of the vehicle interior 20, a second sterilizing device is provided. 52 irradiates the inside of the vehicle interior 20 with ultraviolet rays. Therefore, according to the vehicle 1 of the present embodiment, it is possible to reduce the leakage of ultraviolet rays beyond the range of the irradiation target, such as when the window 12 is open.

Further, the vehicle 1 of the present embodiment includes a battery 924 that supplies electric power to the first sterilizing device 51. The battery 924 charges the power supplied from the accessory power supply 902 or the ignition power supply 901 when the accessory power supply 902 or the ignition power supply 901 is in the on state. Therefore, according to the vehicle 1 of the present embodiment, when the vehicle 1 is in a manned environment such as while traveling, the electric power for the first sterilizing device 51 and the second sterilizing device 52 that are not used is charged. Can be done.

In this case, for example, an ultraviolet shielding plate is provided so as to partition between the driver's seat 4a and the rear seat 4b. When the ultraviolet shielding plate can be taken in and out, and when the ultraviolet shielding plate is in a position where the ultraviolet rays from the second sterilizing device 52 can be shielded, the ultraviolet shielding plate is provided in the vehicle 1 as in the modified example 6. By pressing the switch, the control unit 100 can determine that the measures against ultraviolet leakage of the vehicle 1 are effective. Further, when the ultraviolet shielding plate is transparent, the ultraviolet shielding plate may be always provided so as to partition between the driver's seat 4a and the rear seat 4b.

In this modification, the second sterilizing device 52 is provided on the rear seat 4b side. The second sterilization device 52 of this modification irradiates ultraviolet rays even when the driver is in the driver's seat 4a when the driver's seat 4a is protected from the ultraviolet rays by the ultraviolet shielding plate.

In other words, the irradiation range of ultraviolet rays by the second sterilizing device 52 of this modification does not include the driver's seat 4a in the vehicle interior 20. Further, regardless of the presence or absence of a driver in the passenger compartment 20, when a passenger other than the driver is absent in the passenger compartment 20, the second sterilizing device 52 sterilizes the inside of the passenger compartment 20. The passenger of vehicle 1 is an example of a passenger other than the driver.

FIG. 18 is a flowchart showing an example of the flow of the sterilization process according to the modified example 7 of the first embodiment. In FIG. 18, when the vehicle 1 is a taxi, the sterilization process started immediately after the passenger gets off the vehicle 1 will be described.

First, the control unit 100 of the vehicle control device 10 acquires the determination result of the seating sensor 40b of the rear seat 4b, and acquires the information regarding the opening / closing and locking of the door of the rear seat of the vehicle 1 from CAN or the like. Then, the control unit 100 determines whether or not the passenger gets off from the rear seat and the door of the rear seat of the vehicle 1 is opened / closed and locked (S201). These processes may be executed, for example, by the passenger presence / absence determination unit 101 of the control unit 100.

When it is determined that the passenger is not getting off or the door of the rear seat of the vehicle 1 is not opened / closed and locked (S201 "No"), the control unit 100 repeats the process of S201 and waits.

Then, when the control unit 100 determines that the passenger has disembarked and the door of the rear seat of the vehicle 1 has been opened / closed and locked (S201 "Yes"), whether or not the ultraviolet leakage countermeasure of the vehicle 1 is effective. (S202). In this modification, the control unit 100 determines whether or not the ultraviolet shielding plate is in a predetermined position where the ultraviolet rays from the second sterilizing device 52 can be shielded. For example, the window open / closed state determination unit 102 of the control unit 100 may execute the process.

When the control unit 100 determines that the ultraviolet shielding plate is in the specified position, that is, when it is determined that the ultraviolet leakage countermeasure of the vehicle 1 is effective (S202 “Yes”), the operation command unit 103 of the control unit 100 Turns on the power of the second sterilizing device 52 (S203). In this case, the second sterilizing device 52 irradiates ultraviolet rays to sterilize the rear seat 4b.

Further, when the control unit 100 determines that the ultraviolet leakage countermeasure of the vehicle 1 is not effective (S202 “No”), the process returns to the process of S201. In this case, the irradiation of ultraviolet rays by the second sterilizing device 52 is not executed.

Then, until the door of the rear seat of the vehicle 1 is opened or unlocked (S204 “No”), the second sterilizing device 52 continues to irradiate ultraviolet rays while it is in the ON state.

Then, when the door of the rear seat of the vehicle 1 is opened or unlocked (S204 “Yes”), the control unit 100 switches the power supply circuit of the second sterilizing device 52 to the door. By interlocking with each other, the power of the second sterilizing device 52 is turned off, and the irradiation of ultraviolet rays is completed (S205). When the door of the rear seat of the vehicle 1 is opened, for example, the next passenger may be on board. When the door is opened or unlocked, the irradiation of ultraviolet rays is stopped to prevent the passengers from being exposed to ultraviolet rays.

Here, the process returns to S201 and waits for the timing of starting sterilization after the passengers get off again.

Note that the control unit 100 may determine the open / closed state of the rear seat door based on the information regarding the opening / closing of the rear seat door of the vehicle 1 and the presence / absence of locking from CAN or the like. In this case, when the door of the rear seat of the vehicle 1 is opened or unlocked, the control unit 100 sends a control signal to the second sterilizing device 52 via the second communication unit 120. It may be transmitted and the second sterilizing device 52 may be turned off.

As described above, in this modification, the irradiation range of ultraviolet rays by the second sterilizing device 52 mounted on the vehicle 1 does not include the driver's seat 4a in the vehicle interior 20, and the second sterilizing device 52 is the vehicle. Regardless of the presence or absence of a driver in the room 20, when a passenger other than the driver is absent in the car room 20, the inside of the car room 20 is sterilized. Therefore, according to this modification, when the vehicle 1 is a taxi or the like, the sterilization of the rear seats can be promptly started immediately after the passenger gets off the vehicle while the driver is on the vehicle.

The vehicle 1 may be provided with a plurality of second sterilizing devices 52. In this case, the vehicle 1 may be provided with a second sterilizing device 52 that irradiates the rear seat 4b side with ultraviolet rays and a second sterilizing device 52 that irradiates the driver's seat 4a side with ultraviolet rays. The driver's seat 4a side may be subjected to the same sterilization treatment as in the first embodiment described above.

(Variation Example 8 of the First Embodiment)
Further, when the vehicle 1 is a freight vehicle such as a truck or a trailer equipped with a container, the sterilization device 5 may be provided in the container. For example, as in the second sterilizing device 52c of the modified example 5 described with reference to FIG. 17, a sterilizing device 5 that irradiates ultraviolet rays downward may be provided on the ceiling of the container.

When the second sterilizing device 52c is provided in the container, the second sterilizing device 52c irradiates ultraviolet rays when the inside of the container is unmanned and the door of the container is locked in the closed state. By doing so, the inside of the container is sterilized. The second sterilizing device 52c may be constantly irradiated with ultraviolet rays while the container door is closed and locked, or may be stopped after being irradiated with ultraviolet rays for a predetermined time.

FIG. 19 is a flowchart showing an example of the flow of the sterilization process according to the modified example 8 of the first embodiment.

First, the control unit 100 of the vehicle control device 10 determines whether or not the door of the container is in the closed state and the lock of the door is in the locked state (S301).

In this flowchart, the process is defined on the premise that the door of the container will not be locked when the inside of the container is manned, but the information acquired separately from the sensor or camera in the container. The control unit 100 may determine whether or not the inside of the container is unmanned based on the above.

The control unit 100 repeats the process of S301 and waits until the door of the container is closed and the lock of the door is locked (S301 “No”).

When the control unit 100 determines that the door of the container is closed and the lock of the door is locked (S301 “Yes”), the operation command unit 103 of the control unit 100 is the second sterilizing device 52c. Turn on the power (S302). In this case, the second sterilizing device 52c irradiates ultraviolet rays to sterilize the inside of the container.

The second sterilizer 52c continues to irradiate ultraviolet rays while the container door is open or the door lock is unlocked (S303 “No”).

Then, when the door of the container is opened or the lock of the door is unlocked (S303 “Yes”), the power of the second sterilizing device 52 is turned off, and the irradiation of ultraviolet rays is completed (the irradiation of ultraviolet rays is completed). S304). Here, the process of S301 is returned, and then when the condition of S301 is satisfied, the process of this flowchart is executed again.

As described above, in this modification, the second sterilizing device 52c mounted on the vehicle 1 can automatically start sterilizing the inside of the container immediately after closing the door of the container.

Although only the sterilization inside the container has been described in this modification, the driver's seat 4a of the truck provided with the container may be sterilized in the same manner as in the first embodiment described above.

The functions described as the functions of the control unit 100 of the vehicle control device 10 in the above-mentioned first embodiment and modification are the first sterilization device 51, the second sterilization device 52, or the third sterilization device. It may be a function of the

control units

Further, the sterilization device 54 may be provided for each sheet row.

FIG. 26 is a diagram showing an example of the installation positions of the

sterilizing devices

54e and 54f for each sheet row according to the second embodiment. In the example shown in FIG. 26, two

sterilizing devices

54e and 54f are installed in the vehicle 1. The sterilizer 54e corresponds to the front row including the driver's seat 4a and the passenger seat 4c. Further, the sterilizing device 54f corresponds to the rear row including the

rear seats

4b and 4d. In FIG. 26, since the seat rows are two rows, a front row and a back row, two

sterilizing devices

54e and 54f are installed. However, when the vehicle 1 has three or more rows of seats, the number of seat rows According to this, three or more sterilizing devices 54 are installed. When

such sterilizing devices

54e and 54f are distinguished from the sterilizing devices 54 of other installation forms, they are referred to as "sterilizing devices for each sheet row".

FIG. 27 is a diagram showing an example of the

sterilizing devices

54e and 54f for each sheet row according to the second embodiment viewed from the side. In the example shown in FIG. 27, the sterilizing device 54e corresponding to the front row is installed on the ceiling 11 of the vehicle 1. Further, the sterilizing device 54f corresponding to the rear row is attached to the headrests of the driver's seat 4a and the passenger's seat 4c in the front row. The sterilizing device 54f corresponding to the back row may also be installed on the ceiling 11.

In addition, by combining the sterilizing devices 54a to 54d for each seat and the

sterilizing devices

54e and 54f for each seat row, individual sterilizing devices 54 are installed for some of the seats 4, and the other seats 4 A sterilizer 54 may be installed for each seat row.

Next, the configuration of the sterilization device 54 will be described. FIG. 28 is a diagram showing an example of the internal configuration of the sterilizing device 54 for each seat according to the second embodiment. Although only one sterilizing device 54 is shown in FIG. 28, it is assumed that the sterilizing devices 54a to 54d for each of a plurality of seats have the same configuration.

The sterilization device 54 for each seat includes a control unit 540, a first charged particle generator 541a, a second charged particle generator 541b, a motor 549a, a fan 549b, and a carbon dioxide (CO ₂ ) concentration sensor. It includes 544, a camera 545, a speaker 546, and a microphone 547. Further, the sterilization device 54 is provided with an intake port 548, a first air blow outlet 543a, a second air blow outlet 543b, a first discharge port 542a, and a second discharge port 542b. ..

The control unit 540 includes, for example, a processor such as a CPU, a ROM, and a storage medium such as a flash memory. The control unit 540 controls the operation of each configuration included in the sterilization device 54. For example, the processor executes various programs stored in the ROM to execute a process for controlling the operation of each configuration included in the sterilizer 54.

Further, the control unit 540 includes a communication unit that can communicate with each other with the sterilizing device 54 for each seat. Further, the communication unit can communicate with the car air conditioner 6, the vehicle control device 10, and the like. The communication unit performs wireless communication based on a standard such as Bluetooth (registered trademark), for example. The communication unit may be capable of wired communication, or may be able to connect to CAN-BUS and acquire various information of the vehicle 1. The communication unit may be provided outside the control unit 540. Controlling the car air conditioner 6 or the window 12 by the control unit 540 means that the car air conditioner 6 or the window 12 is externally controlled.

Further, the first charged particle generator 541a generates charged particles for beauty. The second charged particle generator 541b generates charged particles for sterilization. The first charged particle generator 541a for generating charged particles for beauty may be provided as a separate device outside the sterilization device 54. When the first charged particle generator 541a and the second charged particle generator 541b are not particularly distinguished, it is simply referred to as a charged particle generator 541.

Charged particles generated by the first charged particle generator 541a are discharged from the first discharge port 542a. Further, the charged particles generated by the second charged particle generator 541b are discharged from the second discharge port 542b. When the first discharge port 542a and the second discharge port 542b are not particularly distinguished, it is simply referred to as a discharge port 542. In the present embodiment, the discharge port 542 includes a charged particle generator 541 and a discharge port 542 as a “discharge unit”. The discharge port 542 may be used alone as an example of the discharge unit. Further, the entire sterilizing device 54 may be used as an example of the discharging unit.

The motor 549a generates an air flow by driving the fan 549b. Further, the sterilizing device 54 takes in the air in the vehicle interior 20 from the intake port 548. The sterilizer 54 discharges the taken-in air from the first air blow outlet 543a and the second air blow outlet 543b by the fan 549b. The fan 549b is an example of an airflow generator. The airflow generator may be a blower type fan or an axial flow type fan.

The first air blow outlet 543a and the second air blow outlet 543b blow air blow into the passenger compartment 20.

When the first air blow outlet 543a and the second air blow outlet 543b are not particularly distinguished, it is simply referred to as an air blow outlet 543. The air blow outlet 543 is an example of the outlet portion. The air blow outlet 543, the motor 549a, and the fan 549b may be collectively referred to as a blowout portion, or the entire sterilizing device 54 may be used as an example of the blowout portion.

The first air blow outlet 543a is provided in the vicinity of the first outlet 542a. Further, the second air blow outlet 543b is provided in the vicinity of the second discharge port 542b. The first discharge port 542a opens in a direction parallel to the direction of the airflow exiting from the first air blow outlet 543a. The second discharge port 542b opens in a direction parallel to the direction of the airflow exiting from the second air blow outlet 543b. Therefore, the sterilizing device 54 can blow out charged particles in the blowing direction of the air blow.

The first air blow outlet 543a and the second air blow outlet 543b are open toward the target seat 4 of the sterilizer 54. In the example shown in FIG. 28, since the target seat 4 is located below the sterilizing device 54 for each seat, the first air blow outlet 543a and the second air blow outlet 543b are opened downward. Therefore, the discharge port 542 and the air blow outlet 543 blow down the charged particles and the air blow from above the occupant A seated in the seat 4 of the vehicle 1. A configuration in which the discharge port 542 is provided inside the air blow outlet 543 may be adopted.

The microphone 547 collects the sound in the passenger compartment 20. For example, the microphone 547 detects sneezing, coughing, or utterance of Passenger A from the collected sounds. The microphone 547 identifies the location of the sneezing, coughing, or uttering passenger A by identifying the sound source of the collected sneezing, coughing, or utterance. It is not necessary to detect all utterances, and it may be detected when the volume of the voice of the conversation is equal to or higher than the threshold value.

The camera 545 captures the passenger A in the passenger compartment 20. The camera 545 of the present embodiment shall capture a moving image. In the seat-specific sterilization device 54, the camera 545 captures the passenger A seated in the target seat 4 of the seat-specific sterilization device 54. A camera that captures a plurality of passengers A may be provided outside the sterilization device 54 for each seat. The camera 545 detects sneezing, coughing, or utterance of passenger A from the captured image by image processing. The camera 545 transmits the detection result to the control unit 540.

Further, the microphone 547, the camera 545, or the control unit 540 not only locates the passenger A who sneezes, coughs, or speaks, but also estimates the emission direction of the aerosol released by the sneeze, cough, or utterance. You may.

When passenger A sneezes, coughs, or speaks, the aerosol is released from the mouth of passenger A. As the released aerosol spreads in the passenger compartment 20, another passenger A may inhale the aerosol. If the aerosol contains a virus or a bacterium, it is desirable to reduce the retention of the aerosol in the air and reduce the inhalation of the aerosol by the passenger A from the viewpoint of infection control.

Therefore, when the sneezing, coughing, or utterance of the passenger A is detected, the control unit 540 of the sterilizing device 54 controls the second charged particle generator 541b and the motor 549a to release the charged particles. , And increase the air volume of the air blow. As a result, the aerosol floating in the air can be dropped below the face of the passenger A, and the sterilization by the charged particles can be performed quickly. The seat-specific sterilization device 54 executes the process when sneezing, coughing, or utterance of the passenger A seated in the target seat 4 of the sterilization device 54 is detected.

Further, when the sneezing, coughing, or utterance of the passenger A is detected, the control unit 540 of the sterilization device 54 transmits a signal to the car air conditioner 6 and introduces the outside air into the vehicle interior 20 by the car air conditioner 6. Is also good. The outside air introduced by the car air conditioner 6 generally flows from the front to the rear in the vehicle interior 20 and is discharged to the outside of the vehicle through a drafter (ventilation port). The drafter is generally provided behind the vehicle 1. Further, the control unit 540 of the sterilization device 54 may open the window 12 via the vehicle control device 10 to promote ventilation.

As for the order of each operation, for example, the control unit 540 of the sterilizing device 54 drops the aerosol below the face of the passenger A by an air blow from above the passenger A, and then opens the window 12 or the car. The outside air may be introduced by the air conditioner 6.

Generally, in a quiet environment, the airflow in a vehicle room 20 or the like is mainly formed by the influence of airflow by air conditioning, heat rising flow due to physiological heat generation around the human body, and discharge airflow due to coughing or breathing. In particular, around the human body, the influence of the heat rising flow due to physiological fever and the discharge air flow due to coughing or respiration becomes remarkable. The aerosol discharged by the cough of the passenger A is diffused by the cough airflow immediately after being discharged, and is diffused by the airflow in the passenger compartment 20 after the influence of the cough airflow disappears. A large velocity gradient is generated from the center to the periphery of the cough airflow, and a vortex is formed around the cough airflow, causing a phenomenon in which the surrounding air is involved. In addition, even in a quiet environment, the cough airflow attenuates at an extremely high speed, and at the latest, it disappears about 2 seconds after coughing.

Based on such characteristics of the aerosol, the control unit 540 of the sterilization device 54 of the present embodiment reduces the diffusion of the aerosol by stopping the car air conditioner 6 after detecting a cough or the like, and the passenger A is upward. The cough airflow is kept away from the mouth of passenger A by the air blow from the air blow, and the bacteria are eradicated by the charged particles contained in the air blow. Further, by dropping the aerosol with an air blow, it is possible to reduce the aerosol from getting on the updraft in the vehicle interior 20. Further, the control unit 540 of the sterilization device 54 increases the amount of charged particles generated after the sneezing, coughing, or utterance of the passenger A is detected as compared with that before the detection. The period for increasing the amount of charged particles generated may be, for example, about 2 seconds, but is not limited to this. Further, the period of ventilation by introducing air outside the vehicle is, for example, about 3 minutes, but the period is not limited to this.

Further, the control unit 540 may change the amount of opening the window 12 depending on the vehicle speed of the vehicle 1, the weather, or the like. The weather is, for example, the presence or absence of rainfall and the amount of rainfall in the case of rainfall. The control unit 540 may determine the presence / absence of rainfall and the amount of rainfall in the case of rainfall based on the presence / absence of the operation of the wiper of the vehicle 1 and the speed of the operation of the wiper. For example, when it is raining more than the threshold value, the control unit 540 may only introduce the outside air by the car air conditioner 6 without opening the window 12. Further, the control unit 540 of the sterilization device 54 may control the car air conditioner 6 to increase the amount of air blown toward the feet of the passenger A, which is the airflow flowing toward the drafter.

The microphone 547 and the camera 545 are examples of the detection unit in the present embodiment. The microphone 547 may transmit the collected sound to the control unit 540, and the control unit 540 may detect the sneezing, coughing, or utterance of the passenger A from the sound. Further, the camera 545 may transmit the captured image to the control unit 540, and the control unit 540 may detect the sneezing, coughing, or utterance of the passenger A from the image. In this case, the control unit 540 functions as an example of the detection unit.

Further, in the present embodiment, the detection unit includes the microphone 547 or the camera 545, but other sensors may be included in the detection unit. For example, the carbon dioxide concentration sensor 544 may also be an example of the detection unit. For example, the carbon dioxide concentration sensor 544 detects the presence or absence of sneezing, coughing, or speaking of passenger A and the position of passenger A who has sneezing, coughing, or speaking based on the measured carbon dioxide concentration. Is also good. Further, the control unit 540 may detect these based on the measurement result of the carbon dioxide concentration sensor 544. It was

Further, the sterilization device 54 may be provided with only one of the microphone 547 and the camera 545. For example, if the aerosol emission source and emission direction can be specified only by the microphone 547, the camera 545 may be omitted. Further, the sterilizing device 54 may detect the sneezing, coughing, or utterance of the passenger A by another method.

Further, the carbon dioxide concentration sensor 544 measures the carbon dioxide concentration in the air in the passenger compartment 20. The carbon dioxide concentration sensor 544 sends the measurement result to the control unit 540.

When it is determined that the concentration of carbon dioxide in the passenger compartment 20 is not below a predetermined threshold value or the specified time has not elapsed since the start of ventilation (S410 “No”), the control unit 540 repeats the process of S410. ..

Further, when it is determined that the concentration of carbon dioxide in the vehicle interior 20 is equal to or less than a predetermined threshold value and a predetermined time has elapsed from the start of ventilation (S410 “Yes”), the control unit 540 generates charged particles. The operation of increasing the amount and the air volume of the air blow is terminated. Further, the control unit 540 ends the opening of the window 12 and the introduction of the outside air (S411). Then, it returns to S401 and waits until it detects sneezing, coughing, and conversation at a volume higher than the threshold value again.

Further, when the concentration of the exhaust gas of the outside air or other harmful substances is higher than the standard, or when the car air conditioner 6 cannot be externally controlled (S407 “No”), the control unit 540 partially opens the window 12 (S). S412). In this case, instead of all the windows 12, for example, the windows 12c near the driver's seat 4a and the rear seat 4d located diagonally to the driver's seat 4a may be opened. Further, the window 12 in the vicinity of the seat 4 in which the passenger A, which is the source of the aerosol, is seated, and the window 12 in the vicinity of the other seats 4 located on the diagonal line of the seat may be opened. .. Further, in this case, the degree of opening of the window 12 may be less than 1/5. The control unit 540 may change the amount of opening the window 12 depending on the speed of the vehicle 1, the amount of rainfall, or the like.

Further, the operation unit 551a can accept an operation by the user to specify a sterilization guarantee level indicating the strength of sterilization at the sterilization target location. The eradication guarantee level indicates the degree of virus survival rate at the eradication target site. For example, the higher the sterilization guarantee level, the lower the percentage of viruses that survive after sterilization by heating. The sterilization guarantee level may be expressed by a numerical value such as a percentage, or may be expressed in a high / medium / low stage.

Further, the operation unit 551a may accept the user's selection of whether or not to prioritize the reduction of power consumption. For example, in general, the higher the temperature, the shorter the time required for sterilization and the lower the power consumption of the heater. However, if the sterilization time is shortened, viruses or bacteria of a type that requires a long heating time for sterilization are excluded from the sterilization target. In the present embodiment, the user can select whether to prioritize energy saving or a wide range of viruses or bacteria to be sterilized. When the sterilization device 55 operates using a secondary battery such as a battery as a power source, whether or not energy saving is prioritized may be determined by the control unit 551c according to the remaining charge of the battery.

temperature measuring units

552a and 552b are provided on the sterilization target location. It is desirable that a plurality of

temperature measuring units

552a and 552b are installed in the cover 550a at a position far from the heat source on the sterilization target portion. As shown in FIG. 35, in the case of the steering wheel disinfection device 55, for example, two

temperature measuring units

552a and 552b are installed on the rim 132. The number and installation location of the

temperature measuring units

552a and 552b are not limited to this. Hereinafter, when the

temperature measuring units

552a and 552b are not distinguished, they are simply referred to as the temperature measuring unit 552.

FIG. 36 is a diagram showing another example of the appearance of the sterilizing device 55 according to the third embodiment. The sterilization device 55 shown in FIG. 36 is for sterilizing the dashboard 14 of the vehicle 1.

The CPU 551c is connected to the operation unit 551a and the display unit 551b by a HUB or the like so as to be able to communicate with each other. Further, the CPU 551c acquires temperature setting information and season information from a storage device such as a ROM or a flash memory. The CPU 551c may acquire temperature setting information and season information from an external device such as the vehicle control device 10 by wireless communication based on a standard such as Bluetooth (registered trademark). The temperature setting information is information regarding the setting of the heating temperature and the heating time of the heater 555 according to the type of the target virus or bacterium. Further, the season information is information regarding the setting of the heating temperature and the heating time of the heater 555 for each season. Details of temperature setting information and season information will be described later.

Further, the CPU 551c acquires the boarding time of the passenger A of the vehicle 1 based on the information acquired from the vehicle control device 10 or the CAN-BUS or the like. As an example of the usage scene of the sterilization device 55 of the present embodiment, it may be used for sterilization after the end of boarding and before the next boarding. In such a case, the CPU 551c obtains the length of time from the unlocking of the vehicle 1 at the time of the immediately preceding boarding to the turning off of the engine from the vehicle control device 10 or the CAN-BUS, and the length of the time is obtained. It may be determined that the length of the boarding time is long. Further, the length of the boarding time may be the length of time from unlocking the door lock to locking the vehicle 1. In addition, the boarding time may be recorded by the application of the user's smartphone. In this case, the sterilization device 55 may acquire a record of the user's smartphone ride time by communication using Bluetooth (registered trademark) or the like. Alternatively, the CPU 551c may acquire a numerical value indicating the length of the boarding time input by the user to the operation unit 551a at the start of sterilization.

Note that the CPU 551c may adopt a configuration in which the temperature measurement result is acquired from the thermocouple 552.

The CPU 551c controls the temperature controller 553 based on the temperature setting information, the season information, the sterilization target location input to the operation unit 551a by the user, the sterilization guarantee level, and the information on whether to prioritize energy saving. ..

The temperature regulator 553 controls the heater 555 by transmitting a control command value to the SSR 556 based on the temperature measurement result acquired from the thermocouple 552 under the control of the CPU 551c. Further, the control method by the temperature controller 553 is, for example, PID (Proportional-Integral-Differential) control or the like.

The heater 555 is a heat source of the sterilizer 55, and converts the electric power supplied from the power supply 558 via the SSR 556 into heat. The heater 555 is an example of a heating unit. The heater 555 is provided in the cover 550a.

The heater 555 is heated at a different temperature depending on the location to be sterilized under the control of the CPU 551c and the temperature controller 553. For example, when the sterilization target location is specified by the user, the heater 555 heats at a different temperature depending on the designated sterilization target location. Further, when the sterilization guarantee level is specified by the user, the heater 555 heats at a different heating time and temperature according to the designated sterilization guarantee level. Further, the heater 555 may be heated at different heating times and temperatures depending on the length of the boarding time in which the passenger was on the vehicle 1. In addition, the heater 555 heats at different heating times and temperatures depending on the type of virus or bacterium to be removed. Details of the method for determining the heating time and temperature will be described later.

Further, the heater 555 heats at different heating times and temperatures depending on whether energy saving is prioritized or not. For example, if the user inputs whether or not to prioritize energy saving, the heater 555 heats at different heating times and temperatures depending on the user's operation. When it is determined whether or not to give priority to energy saving according to the remaining charge of the battery, the heater 555 heats at a different heating time and temperature according to the remaining charge.

The power supply 558 supplies electric power to the sterilizing device 55. The power supply 558 may be, for example, the ignition power supply of the vehicle 1 or the accessory power supply. It is assumed that the sterilizer 55 can be connected to the ignition power supply or the accessory power supply of the vehicle 1 via the terminal. Alternatively, the power source 558 may be an external power source of the vehicle 1, a portable battery, or the like.

Timer 557 measures the heating time. For example, the timer 557 may be able to control the SSR 556 to stop the heating of the heater 555 when a specified time has passed. Further, the timer 557 may send the measurement result to the CPU 551c.

FIG. 38 is a diagram showing an example of the relationship between the temperature rise of the heater 555 and the time according to the third embodiment. For example, as shown in FIG. 38, the temperature controller 553 has a specified heating temperature after the elapse of a temperature rise time from when the power of the heater 555 is turned on until the temperature of the sterilization target portion reaches the specified heating temperature. When the specified heating time has elapsed, the power of the heater 555 is turned off. The method for controlling the heater 555 is not limited to this.

The sterilization target portion of the sterilization device 55 according to the present embodiment is not limited to the above-mentioned steering wheel 13 and dashboard 14.

FIGS. 39 and 40 are diagrams showing an example of a sterilization target portion of the sterilization device 55 according to the third embodiment. As shown in FIGS. 39 and 49, the sterilization device 55 may be installed at the sterilization target locations Z1 to Z28 in the vehicle compartment 20 of the vehicle 1, respectively. Hereinafter, when each sterilization target location Z1 to Z28 is not distinguished, it is simply referred to as a sterilization target location Z.

Further, depending on the sterilization target portion Z, the shape of the cover 550a includes a cover type that wraps the sterilization target portion Z and a sheet type that hangs on the sterilization target portion Z.

For example, steering wheel 13, shift knob, winker lever, parking brake, accelerator pedal, brake pedal, wiper lever, seat belt metal fittings, and seat, such as Z1, Z7, Z9, Z19-Z21, Z25, and Z27. As for the belt joint, a cover type is suitable as in the steering wheel disinfection device 55 shown in FIG. 34.

Further, for example, like the sterilization target locations Z2-Z6, Z8, Z10-Z18, Z22-Z24, Z26, Z28, the dashboard 14, the back of the front seat 4, the air outlet of the car air conditioner 6, the inner door trim, and the handrail. , Floor, seat surface of seat 4, various switches, center clusters, seat adjustment switch, inner door handle, and window 12, as in the dashboard disinfection device 55 shown in FIG. 35, seats. The mold is suitable.

By sterilizing the air outlet of the car air conditioner 6, it is possible to reduce the amount of adhered droplets drying out and diffusing into the vehicle interior 20. Further, the inner door trim includes a window switch in which the user operates the opening and closing of the window 12. If the seat surface of the seat 4 is antibacterial processed, it may be excluded from the sterilization target portion Z. The center cluster is the range excluding the display part of the car navigation system.

There is a possibility that the virus is attached to the sterilization target portion Z in the passenger compartment 20 due to the touch of the passenger A's hand or the residual droplets emitted from the passenger A's mouth. In particular, steering wheel 13, shift knob, turn signal lever, parking brake, accelerator pedal, brake pedal, dashboard 14, rear of front seat 4, air outlet of car air conditioner 6, inner door trim, handrail, floor, seat surface of seat 4, various types. Switches and center clusters are particularly prone to virus attachment.

As for the window 12, if the passenger A includes an infant, there is a high possibility that the virus will adhere to the passenger A's hand. Further, the sterilizing device 55 for sterilizing the window 12 may adopt a transparent film heater that can be attached to the window glass 1200.

Generally, the heat-resistant temperature of the resin used for the interior of the passenger compartment 20 is about 100 ° C., so the heater 555 sterilizes at a temperature lower than the heat-resistant temperature. Further, the portion having a low heat resistant temperature in the vehicle interior 20 is excluded from the sterilization target of the sterilization device 55 of the present embodiment. For example, displays and combination meters may be excluded from heating because they generally have a low heat resistant temperature. The sterilization target portion Z is not limited to the examples shown in FIGS. 39 and 40.

Further, the heating method may be different depending on the sterilization target portion Z. For example, the metal portion may be heated by direct contact with the heater 555 using heat conduction.

Next, the heating temperature and heating time of the sterilization target portion Z by the sterilization device 55 will be described.

FIG. 41 is a graph showing an example of the relationship between the general treatment time for sterilization and the number of surviving cells of the microorganism to be sterilized. The solid line shown in FIG. 41 is an example of a survival curve expected from an empirical rule, and the dotted line is an example of a survival curve obtained from an actually measured value. As shown in FIG. 41, when a certain microbial cell is heated at a constant temperature (° C.), a linear relationship is generally known between the common logarithm of the number of surviving bacteria of the microbial cell and the treatment time. Therefore, the number of surviving cells decreases with the passage of treatment time.

Further, the D value (decimal reduction time) shown in FIG. 41 is an index showing the resistance of microorganisms. More specifically, the D value is the time required to reduce the number of bacteria at a certain time by one tenth in the linear portion of the graph showing the common logarithm of the number of surviving bacteria of the microbial cell.

Therefore, the reciprocal of the slope of the straight line in the graph is equal to the D value. Therefore, when the D value at a certain temperature is known in advance, the survival rate after t minutes can be expressed by Eq. (1).

N / No in equation (1) indicates the survival rate of microorganisms after t minutes. N indicates the initial number of bacteria. Further, No indicates the number of bacteria at time t.

FIG. 42 is a table showing an example of the heating time for each sterilization guarantee level according to the third embodiment. In the example shown in FIG. 42, the heating time required to reduce the viable cell count is reduced from the initial viable cell count to 1/10, 1/100, and 1/1000000. It is expressed for each of the three levels. In general, advanced sterilization called sterility assurance level (SAL) has a survival probability of 1/1000000.

Also, the time required for sterilization varies depending on the absolute amount of virus or bacteria at the sterilization target site.

FIG. 43 is a table showing an example of the heating time required for each initial viable cell count according to the third embodiment. More specifically, FIG. 43 shows the time required to reduce the initial viable cell count to the specified viable cell count when the initial viable cell count is 100,000, 1 million, or 100 million per 100 g of the object, respectively. Is shown. The specified viable cell count is not limited to, for example, the viable cell count is 1 or less per 100 g of the object.

As shown in FIG. 43, the larger the initial viable cell count, the longer the time required to reduce the viable cell count to the specified viable cell count.

In addition, the survival rate of microorganisms changes depending on the heating temperature at the time of sterilization. A curve obtained by plotting the logarithmic value of the D value with respect to a certain temperature T (° C.) is called a TDT curve (Thermal temperature curve), and FIGS. 44 and 45 are graphs showing an example of the TDT curve. As shown in FIGS. 44 and 45, the TDT curve is generally recognized to be linear. The amount of temperature change at which a certain D value becomes 1/10 or 10 times is called a Z value (° C.).

In other words, the D value is the time to reduce the viable cell count to 1/10 at a certain heating temperature, that is, the heating time required for sterilization. The D value is expressed, for example, in minutes (min) of the heating time. In other words, the Z value is the temperature required to reduce the heating time D value to 1/10.

The relationship between the D value and the Z value can be expressed as in Eq. (2). That is, if the Z value and the D value Dr at the temperature Tr are obtained for a certain microorganism, the D value at a certain temperature T is obtained by using the equation (2).

The Z value is constant for each bacterial species, for example, Z = 5 to 8 ° C for general bacteria and Z = 7 to 11 ° C for heat-resistant spore-forming bacteria. Next, the time and temperature required for eradication of the new coronavirus (Covid-19) and the pathogenic Escherichia coli (O-157), which are considered to be sterilized in the passenger compartment 20, will be described.

FIG. 46 is a graph showing an example of the heating temperature and time required for sterilization of Covid-19 according to the third embodiment. Regarding Covid-19, it is known that 99% of the virus can be removed in 15 minutes when the temperature inside the vehicle is raised to 56 ° C. Since the z value is unknown, the calculation result using the equation (2) for each hypothetical Z value is graphed as shown in FIG. 46. Further, in FIG. 46, the condition is that the sterilization rate is 99%, that is, the survival rate of microorganisms = (1/10) ^ 2. In this case, in Cvid-19, D ₅₆ = 7.5 min.

Further, FIG. 47 is a graph showing an example of the heating temperature and time required for sterilization of O-157 according to the third embodiment. FIG. 47 is a graph of the calculation result using the equation (2), as in FIG. 46. Further, when the sterilization rate is 99%, that is, the survival rate of microorganisms = (1/10) ^ 2, in O-157, D ₅₅ = 27.47 min.

As shown in FIGS. 46 and 47, when Tr-T <0, the larger the Z value, the shorter the time for bacteria to die when the heating temperature is raised by 1 degree. On the other hand, the smaller the Z value, the shorter the time for bacteria to die when the heating temperature is raised by 1 degree. That is, the larger the Z value, the lower the thermal sensitivity, and the smaller the Z value, the higher the thermal sensitivity. Further, since Z = 5 to 8 ° C. for general bacteria and Z = 7 to 11 ° C. for heat-resistant spore-forming bacteria, Z = 12 is a strict condition, that is, a condition having a high sterilizing effect.

Further, since the sterilization device 55 of the present embodiment is premised on being used in the vehicle interior 20, a virus or bacterium that requires overheating of the interior resin in the vehicle compartment 20 at a heat resistant temperature or higher for sterilization is required. Is excluded.

FIG. 48 is a table showing an example of the heating temperature, D value, and Z value required for sterilization of general non-heat-resistant microorganisms. As shown in FIG. 48, most of the non-thermostable microorganisms can be sterilized by heating at less than 100 ° C. Further, for example, a virus having an envelope, such as Covid-19, is included in non-heat-resistant microorganisms because the envelope is destroyed and inactivated by heating at a predetermined temperature for a predetermined time or longer.

On the other hand, FIG. 49 is a table showing an example of the heating temperature, D value, and Z value required for sterilization of general heat-resistant microorganisms. For example, in order to sterilize a bacterium classified as a spore-forming bacterium, heating at 100 ° C. or higher is required. Such heat-resistant microorganisms are excluded from the sterilization target of the sterilization device 55 of the present embodiment.

FIG. 50 is a graph showing an example of the heating temperature and time required for eradication of Clostridium botulinum type A, calculated by the same method as in FIGS. 46 and 47. More specifically, FIG. 50 shows an example of D ₁₀₄ = 17.6 min. As shown in the table of FIG. 49 and “N” shown in FIG. 50, eradication of Clostridium botulinum type A requires overheating at 104 ° C. for 17.6 minutes. Further, when the heating temperature is less than 100 ° C., it takes a long time of 100 minutes or more to sterilize Clostridium botulinum type A.

In the sterilizing device 55 of the present embodiment, microorganisms having Tr-T> 0 and Tr exceeding the resin heat resistant temperature in the passenger compartment 20 are not targeted for sterilization. As shown in FIG. Even if Tr-T> 0, it is possible to calculate the numerical values of the heating temperature and the heating time, but this is because the heating time increases. In addition, in calculation, even if the numerical values of the heating temperature and the heating time can be calculated, the microorganisms that cannot be killed or inactivated may not meet the temperature at which the target microorganisms are actually killed or inactivated. This is because it may remain after heating.

Further, as described above, the heating temperature and heating time required for sterilization also differ depending on the initial viable cell count, that is, the amount of virus or bacterium present before the start of sterilization. In the case of vehicle 1, for example, as the boarding time of passenger A becomes longer, the number of viable bacteria in the passenger compartment 20 may increase. The tables shown in FIGS. 51 and 52 show suitable combinations of heating temperature and heating time when sterilizing Covid-19 and O-157.

FIG. 51 is a table showing an example of the heating time for each of the initial viable cell count, heating temperature, survival rate, and residual rate of Covid-19 according to the third embodiment. Since it is difficult to measure the actual initial viable cell count of the vehicle 1 each time the sterilization treatment is performed, in FIG. 51, the initial viable cell count of Covid-19 is estimated according to the length of the boarding time. In the example shown in FIG. 51, it is estimated that the longer the boarding time, the higher the initial viable cell count.

Further, as shown in FIG. 51, the heating time varies depending on the heating temperature and the residual rate (survival rate) of the target virus or bacterium. The upper limit of the heating temperature and the time may be set according to the heat-resistant temperature of the sterilization target portion. The heat resistant temperature of the sterilization target portion may be input by the user from the operation unit 551a. It may be stored in a ROM or the like. In addition, the residual rate (survival rate) of the target virus or bacterium is determined according to the sterilization guarantee level input by the user.

Further, as described above, it is known that for Covid-19, 99% of the virus can be removed in 15 minutes when the temperature inside the vehicle is raised to 56 ° C. Therefore, when the sterilization target is Covid-19, the sterilization device 55 heats the sterilization target portion at a temperature of at least 56 ° C. or higher. In the example shown in FIG. 51, an example of heating at 65 ° C. or 75 ° C. is shown.

Further, in FIG. 51, the initial viable cell count that is assumed to adhere to the sterilization target portion when the boarding time is 10 minutes is set as the minimum value. The value of 10 minutes is not limited.

FIG. 52 is a table showing an example of the heating time for each of the initial viable cell count, heating temperature, survival rate, and residual rate of O-157 according to the third embodiment. Even if the boarding time is the same, the heating temperature and time required for sterilization differ depending on the type of virus or bacterium to be sterilized.

The tables shown in FIGS. 51 and 52 are examples of temperature setting information in this embodiment. In this way, the temperature setting information may be stored in the ROM or the like of the sterilization device 55 for each type of virus or bacterium to be sterilized. As described above, the control unit 551c reads the temperature setting information from a storage device such as a ROM. Alternatively, the control unit 551c may dynamically calculate the temperature setting information during the sterilization process.

The initial viable cell count may differ depending on the location to be sterilized. For example, since the number of adhered bacteria varies depending on the number of finger contacts and the amount of droplets, the heating temperature and the heating temperature and the part where there is little finger contact such as the steering wheel 13 or switches and the part where there is little finger contact such as the inner doorknob The time may be different. For example, when the sterilization target portion is a portion where there is little contact with fingers, the relationship between the length of the boarding time and the initial viable cell count may be weak, so that the control unit 551c does not have to determine the boarding time. In this case, regardless of the boarding time, the heating temperature and time associated with the boarding time of 10 minutes in the temperature setting information may be applied.

Further, as described in FIGS. 51 and 52, the heating temperature and time required for sterilization differ depending on the type of virus or bacterium to be sterilized.

More specifically, the type of virus or bacterium that is prevalent may differ depending on the season. For example, O-157 occurs frequently in August to September. Influenza occurs frequently from early December to early February. In addition, Covid-19 occurs regardless of the season.

Season information is, for example, information in which a date corresponding to a season is associated with a type of virus or bacterium that frequently occurs in the season. The control unit 551c may read the season information from a storage device such as a ROM and select the temperature setting information according to the type of virus or bacterium that is likely to occur in the current season. Further, the control unit 551c may determine the type of virus or bacterium to be removed according to not only the season but also the temperature or humidity. For example, the control unit 551c shall determine the type of virus or bacterium to be removed according to the season, temperature, or humidity.

Next, the flow of the sterilization process executed by the sterilizer 55 of the present embodiment configured as described above will be described.

FIG. 53 is a flowchart showing an example of the flow of the sterilization process according to the third embodiment. First, the operation unit 551a of the sterilization device 55 accepts an operation of designating a sterilization target location by the user (S601). When the sterilization target location is predetermined as in the steering wheel sterilization device 55, it is not necessary to specify the sterilization target location.

Next, the operation unit 551a of the sterilization device 55 accepts the user's designation of the sterilization guarantee level (S602).

Then, the control unit 551c of the sterilization device 55 determines whether or not to determine the boarding time according to the sterilization target location (S603).

For example, when the sterilization target location is a location such as the dashboard 14 where the initial bacterial count changes according to the boarding time, the control unit 551c determines to determine the boarding time (S603 “Yes”). In this case, the heating temperature and the heating time vary depending on the riding time of the vehicle 1.

Then, the control unit 551c determines whether or not to prioritize the reduction of power consumption based on the selection by the user (S604).

When it is selected to prioritize the reduction of power consumption (S604 "Yes"), viruses or bacteria of the type having a heating time longer than the specified length for sterilization are excluded. In this case, the control unit 551c determines that the heating is performed at the first heating temperature for the first heating time based on the temperature setting information (S605).

The heater 555 starts heating under the control of the control unit 551c (S606). Then, the heater 555 ends heating when the time determined by the control unit 551c elapses. In this case, the sterilization treatment is completed (S607). For example, when the control unit 551c determines that the heating is performed at the first heating temperature for the first heating time, the heater 555 heats at the first heating temperature for the first heating time.

Further, when it is selected not to give priority to the reduction of power consumption (S604 "No"), the type of virus or bacterium having a heating time longer than the specified length for sterilization is also subject to sterilization. In this case, the control unit 551c determines that the heating is performed at the second heating temperature for the second heating time based on the temperature setting information (S608).

If the sterilization target location is a location where the initial bacterial count does not change according to the boarding time, the control unit 551c determines that the boarding time is not determined (S603 "No"). In this case, the heating temperature and the heating time do not change depending on the riding time of the vehicle 1.

Then, the control unit 551c determines whether or not to prioritize the reduction of power consumption based on the selection by the user (S609).

When it is selected to prioritize the reduction of power consumption (S609 "Yes"), the control unit 551c determines that the heating is performed at the third heating temperature for the third heating time (S610) based on the temperature setting information.

Further, when it is selected not to give priority to the reduction of power consumption (S609 “No”), the control unit 551c determines that the heating is performed at the fourth heating temperature for the fourth heating time based on the temperature setting information (S609 “No”). S611).

In the present embodiment, the first temperature and the third temperature are both higher than the second temperature and the fourth temperature. Further, the second heating time is assumed to be the longest among the first heating time, the second heating time, the third heating time, and the fourth heating time. Further, the third heating time shall be the shortest among the first heating time, the second heating time, the third heating time, and the fourth heating time.

As a specific example, when the boarding time is 60 minutes, the first temperature is 75 degrees and the first heating time is 2.35 minutes. When the boarding time is 60 minutes, the second temperature is 65 degrees and the second heating time is 96.77 minutes. If the initial viable cell count that is expected to adhere to the sterilized target area is set to the minimum value when the boarding time is 10 minutes, the third temperature is 75 degrees and the third heating time is 0.59 minutes. The fourth temperature is 65 degrees and the fourth heating time is 24.19 minutes.

As described above, the sterilization device 55 of the present embodiment has a cover 550a capable of covering at least a part of the configuration in the vehicle interior 20 and a temperature for measuring the temperature of the sterilization target portion. It is provided with a measuring unit 552, a heater 555 provided on the cover 550a, and a control unit 551c for controlling the heating time and heating temperature by the heater 555. Therefore, according to the sterilization device 55 of the present embodiment, the sterilization target portion in the vehicle can be heated at a temperature and time suitable for sterilization.

For example, when a user changes like a rental car, there is a need to sterilize the inside of the car after the user uses it and before the next user gets on the car. However, since there is a limit to the temperature rise inside the car with a car air conditioner or the like, it may be difficult to keep the inside of the car at a temperature suitable for sterilization for the time required for sterilization. In addition, heating beyond the temperature and time required for sterilization may consume a large amount of energy or damage the interior. On the other hand, according to the sterilization device 55 of the present embodiment, the temperature and the heating time of the sterilization target portion can be controlled, so that wasteful time and energy consumption can be reduced and the sterilization can be performed efficiently. Bacteria can be done.

Further, the sterilization device 55 of the present embodiment can accept an operation of designating a sterilization target location by the user, and heats the sterilization device 55 at a different temperature according to the designated sterilization target location. Therefore, according to the sterilization device 55 of the present embodiment, the temperature and the heating time can be controlled according to the user's desired sterilization target location.

Further, the sterilization apparatus 55 of the present embodiment can accept an operation of designating a sterilization guarantee level indicating the strength of sterilization at the sterilization target location by the user, and differs depending on the designated sterilization guarantee level. Heat at heating time and temperature. Therefore, according to the sterilization apparatus 55 of the present embodiment, the temperature and the heating time can be controlled according to the desired sterilization guarantee level of the user.

Further, the sterilization device 55 of the present embodiment can accept an operation by the user to specify whether to prioritize the reduction of power consumption and the wide range of the type of virus or bacterium to be sterilized. It is heated at different heating times and temperatures depending on whether the reduction in power consumption and the wide range of viruses or types of bacteria to be sterilized are selected. Therefore, according to the sterilization device 55 of the present embodiment, sterilization can be performed with a heating time and temperature according to the needs.

Further, the sterilizing device 55 of the present embodiment heats at different heating times and temperatures according to the length of the boarding time in which the passenger A is on the vehicle 1. Therefore, according to the sterilization device 55 of the present embodiment, sterilization can be efficiently performed at an appropriate heating time and temperature according to the length of the riding time.

Further, the sterilizing device 55 of the present embodiment heats at different heating times and temperatures depending on the type of virus or bacterium to be removed. Therefore, according to the sterilization device 55 of the present embodiment, sterilization can be appropriately performed according to the type of the target virus or bacterium.

Further, the sterilizing device 55 of the present embodiment determines the type of virus or bacterium to be removed according to the season, temperature, or humidity. Therefore, according to the sterilizing device 55 of the present embodiment, the season. It can be sterilized appropriately according to the type of virus or bacterium that is likely to be infected, depending on the temperature, or humidity.

Further, the sterilization device 55 of the present embodiment includes a ROM or a flash memory for storing temperature setting information regarding the setting of the heating temperature and the heating time according to the type of the target virus or bacterium. Therefore, according to the sterilization apparatus 55 of the present embodiment, the heating temperature and the heating time can be quickly determined by referring to the temperature setting information at the start of sterilization.

Further, in the sterilization device 55 of the present embodiment, whether or not the heating temperature and the heating time fluctuate according to the boarding time of the vehicle 1 and the reduction of power consumption are within the range of the type of virus or bacterium to be sterilized. Suitable heating time and heating temperature can be determined depending on whether or not priority is given to the size of the virus.

Further, the control unit 551c of the sterilization device 55 of the present embodiment is provided outside the cover 550a. Therefore, the control unit 551c can be protected from overheating for sterilization.

Further, the cover 550a of the sterilization device 55 of the present embodiment has a shape corresponding to a sterilization target location or a sheet-like shape. Therefore, according to the sterilization device 55 of the present embodiment, it can be easily installed at the user's desired sterilization target location.

(Fourth Embodiment)
In the fourth embodiment, an in-vehicle sterilizing device 5 for spraying a liquid containing a sterilizing component as a mist for sterilizing the vehicle interior 20 and a vehicle 1 provided with the sterilizing device 5 will be described. ..

FIG. 54 is a diagram showing an example of a vehicle 1 provided with the sterilizing device 56 according to the fourth embodiment. Similar to the first embodiment, the vehicle 1 of the present embodiment includes a vehicle body 2 and two pairs of wheels 3 arranged on the vehicle body 2 along a predetermined direction. The two pairs of wheels 3 include a pair of front tires 3f and a pair of rear tires 3r. Further, the vehicle 1 is provided with a window 12 and a plurality of

seats

4a and 4b on which the passenger Aga can be seated, as in the first embodiment.

Further, the sterilization device 56 can be mounted on the vehicle 1 and is an example of the spray unit and the sterilization device for vehicles in the present embodiment. It should be noted that not the entire sterilizing device 56 but only the nozzle that sprays the mist may be used as an example of the spraying unit.

The sterilizing device 56 of the present embodiment sprays a liquid containing a sterilizing component into the vehicle interior 20. The sprayed mist-like disinfectant is called mist.

The liquid containing the sterilizing component is, for example, a substance containing the sterilizing component dissolved in a liquid solvent such as water or alcohol, or alcohol itself. The liquid containing the sterilizing component is, for example, hypochlorite water, but is not limited thereto. In the first embodiment, the liquid containing the sterilizing component does not contain alcohol, but in the present embodiment, the mist vaporizes in the air inside the vehicle interior 20 and does not adhere to the interior. May use alcohol as a liquid containing a sterilizing component. Hereinafter, the liquid containing the sterilizing component is referred to as a sterilizing liquid.

When the space is filled with a substance containing a sterilizing component for sterilization in the passenger compartment 20, the liquid state cannot be circulated by the wind of an air conditioner such as a car air conditioner 6, so the sterilization device 56 is used. It is preferable to spray and vaporize. Further, when the disinfectant device 56 sprays the disinfectant solution and reaches the dashboard or the floor as mist, traces of mist grains remain on the dashboard or the floor material is absorbed and only the floor material is left. It may be sterilized intensively. Therefore, in order to evenly sterilize the inside of the vehicle interior 20, it is desirable that the sprayed mist vaporizes before reaching the resin portion and the floor.

In order to promote the vaporization of mist, the mist is made finer, the mist is blown in a high temperature environment, the distance from the place where the mist is sprayed to the resin part and the floor material is secured, and the mist reaches the resin part and the floor material. It is effective to stir with an air conditioner before doing so.

When the air conditioner is driven to vaporize the mist, the charge amount of the battery is consumed. Therefore, when the promotion of vaporization by other means is emphasized, the disinfectant device 56 has a high temperature in the passenger compartment 20, resulting in humidity. It is desirable to install it in a position where the temperature is low. Generally, the temperature in the vehicle interior 20 rises above the windshield and the side window, so that when the mist is sprayed from above the window 12, vaporization can be promoted. Therefore, it is desirable that the sterilizing device 56 sprays mist from a high position in the vehicle interior 20 near the ceiling. In addition, since the spray position is high, the distance until the mist reaches the dashboard or the floor becomes long, so that vaporization can be promoted.

The mist generation method can be either spray-like or ultrasonic atomization, but because it is near the ceiling, the temperature inside the vehicle rises when exposed to sunlight, and vaporization is further promoted.

Therefore, the sterilizing device 56 of the present embodiment is installed at least above the lower side of the window 12 of the vehicle 1. More specifically, the sterilizing device 56 may be installed at a position higher than the midpoint in the vertical direction of the window 12. Further, the vehicle 1 is provided with a humidity sensor 561a and a temperature sensor 561b. In the present embodiment, the humidity sensor 561a and the temperature sensor 561b are included in the sterilizing device 56, but may be configured outside the sterilizing device 56. Hereinafter, in the present embodiment, the humidity sensor 561a and the temperature sensor 561b are collectively referred to as a temperature / humidity sensor 561. The temperature / humidity sensor 561 is an example of the measurement unit of the present embodiment.

FIG. 55 is a diagram showing an example of the installation position of the spray-type sterilizing device 56a according to the fourth embodiment. The sterilization device 56a shown in FIG. 55 includes a fluid nozzle 560a, a light 7a, and a temperature / humidity sensor 561. The other configurations of the sterilizer 56a will be described later with reference to FIG. 57. Although the power supply circuit is not shown in FIG. 55, the sterilization device 56a receives power from, for example, the battery of the vehicle 1.

The outer plate 11a on the upper surface of the vehicle 1 is generally formed of metal. The outer plate 11a is an example of the outer wall of the ceiling. Further, the interior member 11b of the vehicle 1 located below the outer plate 11a on the upper surface of the vehicle 1 is formed of resin or fabric. In some cases, a member for soundproofing or heat shielding is sandwiched between the outer plate 11a and the interior member 11b. The interior member 11b is an example of the inner wall of the ceiling.

In the present embodiment, the outer plate 11a and the interior member 11b are collectively referred to as the ceiling 11. The ceiling 11 is at the highest position in the vehicle body 2, and connects the windshield 121 and the rear glass 122 of the vehicle body 2.

The fluid nozzle 560a is a spray that ejects the disinfectant solution in the form of mist. The fluid nozzle 560a is fixed to the ceiling 11 of the vehicle 1. More specifically, the fluid nozzle 560a is fixed to the outer plate 11a or the interior member 11b. In the example shown in FIG. 55, the fluid nozzle 560a is fixed to the outer plate 11a on the upper surface of the vehicle 1 by the fixing member 151. The fixing member 151 is fixed to the frame of the vehicle body 2, for example. The fluid nozzle 560a is also referred to as a spray nozzle.

Further, the fluid nozzle 560a is provided separately from the air outlet of the car air conditioner 6 which is the air conditioning equipment of the vehicle 1.

In the example shown in FIG. 55, the fluid nozzle 560a is provided between the outer plate 11a and the interior member 11b. An opening is provided at a position corresponding to the fluid nozzle 560a of the interior member 11b, and only the tip of the fluid nozzle 560a is exposed to the outside of the interior member 11b. The mist sprayed from the tip of the fluid nozzle 560a is discharged to the outside of the interior member 11b, that is, into the vehicle interior 20.

The fixing member 151 may support the fluid nozzle 560a so that the angle can be changed. For example, the fluid nozzle 560a may swing in the left-right direction, that is, in the width direction of the vehicle 1. If the opening of the interior member 11b is provided as a long hole in the left-right direction, such a swing function can be supported. Further, the fluid nozzle 560a may be provided on the outside of the interior member 11b.

The fluid nozzle 560a sprays the mist of the disinfectant liquid. The fluid nozzle 560a is provided at an oblique downward angle or a horizontal angle. It is desirable that the fluid nozzle 560a is provided at an angle diagonally downward rather than downward, for example, so that the position where the mist is sprayed is far from the resin portion or the floor.

Generally, a mist-like liquid is heavier than air, so the mist injected from the fluid nozzle 560a gradually falls downward and is agitated with the surrounding air to evaporate. As a result, the sterilizing component is sprayed on the air in the vehicle interior 20. Therefore, it is possible to secure the stirring time with the air when the fluid nozzle 560a is oriented diagonally downward or sideways rather than downward, and even if the air conditioning such as the car air conditioner 6 is not operating, a large amount of the disinfectant liquid is vaporized. be able to. Further, it is preferable that the tip of the fluid nozzle 560a faces the space and a distance can be taken from the seat 4 and the floor.

Further, the light 7a irradiates the mist sprayed from the fluid nozzle 560a with visible light. The light 7a is fixed to the inside of the outer plate 11a by, for example, the fixing member 152. The fixing member 152 is fixed to the frame of the vehicle body 2, for example. An opening is provided at a position corresponding to the tip of the light 7a of the interior member 11b, and the tip of the light 7a is exposed to the outside of the interior member 11b.

Although the mist may be difficult to see, the user can easily grasp that the mist is sprayed from the fluid nozzle 560a by irradiating the light 7a. The light 7a is an example of the irradiation unit in the present embodiment.

The installation position of the fluid nozzle 560a is not limited to the example shown in FIG. 55, and may be provided in the center of the ceiling 11, the pillar, the headrest of the seat 4, or the like. Further, the sterilization device 56 may be provided with a plurality of fluid nozzles 560a.

Further, the temperature / humidity sensor 561 is provided in the vicinity of the fluid nozzle 560a and measures the temperature and humidity in the vicinity of the fluid nozzle 560a. Since evaporation does not proceed in a high humidity environment, spraying is intermittent to prevent the humidity from rising too high, or the sterilization device 56 operates the car air conditioner 6 to circulate the air inside the car and the humidity is high. It is also possible to reduce the uneven distribution of air and spray while heating to reduce the humidity. By using the spray of the sterilizing liquid and the car air conditioner 6 in combination, as a result, it is possible to reduce that the aqueous solution of the sterilizing component does not evaporate and falls and adheres to the inside of the car. The control of the car air conditioner 6 will be described later.

FIG. 56 is a graph showing an example of the relationship between general humidity and dew condensation. As a cause of dew condensation, the amount of water per cubic meter that air can contain is determined by the temperature. When the relative humidity in the passenger compartment 20 is 100%, if the humidity rises due to the spraying of the disinfectant liquid, the mist does not evaporate, which causes the mist to fall as it is. Also, with the same amount of water, the higher the dry-bulb temperature (air temperature), the lower the relative humidity, so the sprayed mist evaporates faster.

For this reason, when the sterilization device 56 and the air-conditioning operation such as the car air conditioner 6 capable of blowing air into the vehicle interior 20 are used in combination, the state where the high humidity portion is unevenly distributed in the vehicle interior 20 due to the mist can be eliminated, or the heating can be used. The relative humidity can be lowered to promote the evaporation of mist. Since operating the car air conditioner 6 consumes a large amount of energy, the disinfectant device 56 of the present embodiment promotes the vaporization of mist by the installation position of the fluid nozzle 560a and the like, and further, the condition that dew condensation is estimated to occur. In conjunction with the air conditioning operation of the car air conditioner 6 and the like.

FIG. 57 is a diagram showing an example of the configuration of the spray-type sterilizing device 56a1 according to the fourth embodiment. More specifically, the sterilizing device 56a1 is an example of the spray-type sterilizing device 56 described with reference to FIG. 55. As shown in FIG. 57, the disinfectant device 56a1 includes a fluid nozzle 560a, a light 7a, a humidity sensor 561a, a temperature sensor 561b, a liquid electromagnetic valve 564a, a liquid tank 563, and a pressurized gas storage unit 5631. , The remaining amount sensor 5632 and the control unit 565 are provided. The air conditioner of the vehicle 1 shown in FIG. 57 is, for example, a car air conditioner 6. Further, the car air conditioner 6 is not included in the sterilizing device 56a1. The liquid tank 563, the pressurized gas storage unit 5631, the remaining amount sensor 5632, and the control unit 565 do not have to be provided on the ceiling 11.

The liquid tank 563 stores the sterilizing liquid. Further, the disinfectant liquid stored in the liquid tank 563 and the pressurized gas stored in the pressurized gas storage unit 5631 reach the liquid solenoid valve 564a through one liquid pipe, and reach the liquid solenoid valve 564a from the fluid nozzle 560a. It is ejected as a mist.

The remaining amount sensor 5632 measures the sterilized liquid in the liquid tank 563, and transmits the sensing result of the remaining amount of liquid, that is, the measured remaining amount of liquid to the control unit 565.

The humidity sensor 561a transmits humidity information related to the measured humidity to the control unit 565. Further, the temperature sensor 561b transmits the temperature information regarding the measured temperature to the control unit 565.

The control unit 565 includes, for example, a processor such as a CPU, a ROM, and a storage medium such as a flash memory. For example, the processor executes various processes stored in the ROM to execute various processes. In the example shown in FIG. 57, the determination unit 5651 of the control unit 565 is a function realized by the processor executing various programs stored in the ROM. The determination unit 5651 determines whether or not spraying is possible, whether or not the light 7a needs to be turned on, or the content of the instruction to the car air conditioner 6 based on the sensing result of the remaining amount of liquid, temperature, humidity, and the like.

The control unit 565 controls the liquid solenoid valve 564a to spray the sterilizing liquid as a mist. Further, the control unit 565 controls and turns on the light 7a when spraying mist.

The control unit 565 controls the car air conditioner 6 which is the air conditioner of the vehicle 1 according to the temperature or humidity. For example, it is assumed that the control unit 565 can communicate with the car air conditioner 6 by wireless communication based on a standard such as Bluetooth (registered trademark).

Further, the control unit 565 receives an input of an operation for starting sterilization by the user from an operation unit (not shown). Further, when the remaining amount of the sterilizing liquid in the liquid tank 563 is less than the amount used for one sterilization, the control unit 565 indicates that there is no remaining amount of the sterilizing liquid in the display unit (not shown). Or display the image. The operation unit and the display unit may be shared with, for example, the touch panel of the car navigation system of the vehicle 1, or the operation unit and the display unit for the sterilization device 56 may be provided. For example, the operation unit may be a switch button or the like.

FIG. 58 is a flowchart showing an example of the flow of the sterilization process by the spray-type sterilization device 56a1 according to the fourth embodiment.

First, the determination unit 5651 of the control unit 565 of the sterilization device 56a1 determines whether or not the input of the operation for starting the sterilization by the user has been accepted (S701). If it is determined that the input of the operation for starting sterilization by the user is not accepted (S701 "No"), the determination unit 5651 repeats the process of S701.

Further, the remaining amount sensor 5632 confirms by measuring the remaining amount of the sterilizing liquid, and transmits the measured remaining amount of the liquid to the control unit 560 (S702). The determination unit 5651 determines whether or not the remaining amount of the sterilizing liquid in the liquid tank 563 is equal to or more than the amount used for one sterilization based on the remaining amount of the sterilizing liquid measured by the remaining amount sensor 5632. Judgment (S703).

When the remaining amount of the sterilizing liquid in the liquid tank 563 is equal to or greater than the amount used for one sterilization (S703 “Yes”), the determination unit 5651 acquires the temperature and humidity measurement results from the temperature / humidity sensor 561. (S704).

The determination unit 5651 determines whether or not the humidity is less than 80% based on the acquired measurement result (S705). 80% is an example of the first threshold value in this embodiment. The value of the first threshold value is not limited to this.

When the humidity is equal to or higher than the first threshold value, the sterilizing device 56a operates the car air conditioner 6 before spraying the sterilizing liquid. Specifically, when the humidity is 80% or more (S705 “No”), the determination unit 5651 then determines whether or not the humidity is less than 95% (S706). 95% is an example of the second threshold in this embodiment. The value of the second threshold value is not limited to this.

Then, when the humidity is 95% or more (S706 "No"), the determination unit 5651 controls the car air conditioner 6 to turn on the heating function of the air conditioner (S707). As a result, warm air is blown from the air outlet of the car air conditioner 6, the temperature inside the vehicle interior 20 rises, and the humidity decreases.

When the humidity is less than 95% (S706 “Yes”), the determination unit 5651 controls the car air conditioner 6 to turn on the air conditioning function (S708). As a result, air at room temperature is blown from the air outlet of the car air conditioner 6. Simply blowing air consumes less power than heating.

If the humidity is less than 80% (S705 “Yes”), the determination unit 5651 does not heat or blow air by the car air conditioner 6.

Then, the determination unit 5651 controls the liquid solenoid valve 564a to spray the sterilizing liquid as a mist. Further, the determination unit 5651 controls and turns on the light 7a when spraying mist (S709).

Next, the determination unit 5651 determines whether or not the scheduled spraying time has elapsed from the start of spraying (S710). The scheduled spraying time per sterilization shall be predetermined. The determination unit 5651 repeats the processes of S709 and S710 while it is determined that the scheduled spraying time has not elapsed (S710 “No”).

Then, when the determination unit 5651 determines that the scheduled spraying time has elapsed (S710 “Yes”), the determination unit 5651 controls the liquid solenoid valve 564a to stop the mist spraying. Further, the determination unit 5651 controls the light 7a to turn off the light 7a when the mist spraying is stopped (S711). Then, the determination unit 5651 controls the car air conditioner 6 to turn off the air conditioner (S712). If the car air conditioner 6 is not operated before spraying the mist, the processing of S712 is unnecessary. Then, the process returns to S701 and waits for the start of sterilization.

When the remaining amount of the sterilizing liquid in the liquid tank 563 is less than the amount used for one sterilization (S703 “No”), the determination unit 5651 displays the remaining amount of the sterilizing liquid on the display unit. Display that there is no such thing (S713). Then, the process returns to the process of S701.

In this flowchart, the trigger for starting the sterilization process is an operation by the user, but the trigger is not limited to this. For example, the processing of this flowchart may be started when a certain time has elapsed since the door of the vehicle 1 was locked after the user got off the vehicle. Alternatively, when the user disembarks after performing a sterilization reservation operation from the operation unit, the processing of this flowchart may be started at the reservation time.

FIG. 59 is a diagram showing another example of the configuration of the spray-type sterilizing device 56a according to the fourth embodiment. More specifically, the sterilizing device 56a2 shown in FIG. 59 is another example of the spray-type sterilizing device 56 described with reference to FIG. 55.

Unlike the sterilizing device 56a1 described with reference to FIG. 57, the sterilizing device 56a2 shown in FIG. 59 includes a compressor 566 and a pressure sensor 5661. Further, the sterilization device 56a2 includes a liquid solenoid valve 564a and a compressed air solenoid valve 564b. Further, the sterilization device 56a1 is not provided with the pressurized gas storage unit 5631.

The compressor 566 compresses the air and sends it to the liquid tank 563 and the compressed air solenoid valve 564b. The pressure sensor 5661 measures the pressure generated by the compressor 566 and transmits the measurement result to the control unit 565.

Further, in the configuration, the disinfectant liquid is sent from the liquid solenoid valve 564a, and the compressed air is sent from the compressed air solenoid valve 564b to the fluid nozzle 560a. By using compressed air in this way, the mist particles can be made finer than those of the sterilizing device 56a1 described with reference to FIG. 57. For example, in the configuration of FIG. 59, the mist particles can have a diameter of several microns. Generally, if the size of the mist particles is 10 um or less, it is difficult for water droplets to adhere to the dashboard 14 or the floor.

FIG. 60 is a flowchart showing another example of the flow of the sterilization process by the spray-type sterilization device 56a according to the fourth embodiment.

The process from the process of determining whether or not the input of the start operation of S801 is accepted to the process of turning on the ventilation of the air conditioner of S808 is the same as that of S701 to S708 described with reference to FIG. 58.

Then, in the sterilization device 56a, the control unit 565 activates the compressor 566 (S809).

Next, the determination unit 5651 of the control unit 565 determines whether or not the pressure of the compressor 566 has reached a constant pressure based on the measurement result of the pressure sensor 5661 (S810). The constant pressure is, for example, a predetermined threshold value that serves as a reference for pressure.

If the pressure of the compressor 566 has not reached a certain pressure (S810 "No"), the process of S810 is repeated.

Further, when the pressure of the compressor 566 reaches a constant pressure (S810 “Yes”), the control unit 565 turns on the compressed air solenoid valve 564b and starts discharging the compressed air (S811). Then, the control unit 565 determines whether or not a certain time has elapsed since the compressed air solenoid valve 564b was turned on (S812).

The process of S812 is repeated until a certain time elapses after the compressed air solenoid valve 564b is turned on (S812 “No”).

When a certain period of time has elapsed since the compressed air solenoid valve 564b was turned on (S812 “Yes”), the control unit 565 turns the liquid solenoid valve 564a on, starts discharging mist, and lights. 7a is turned on (S813).

The process from determining the elapse of the scheduled spraying time of S814 to the process of turning off the liquid solenoid valve 564a and the light 7a of S815 is the same as the process from S710 to S711 in FIG.

Then, the control unit 565 turns off the compressed air solenoid valve 564b and stops the discharge of the compressed air (S816). Then, the determination unit 5651 controls the car air conditioner 6 to turn off the air conditioner (S817).

Then, the control unit 565 turns off the compressor 566 and stops the discharge of the compressed air (S818). The processes of S816 to S818 are in no particular order.

Further, the process of indicating that there is no remaining amount of the sterilizing solution in S819 is the same as the process of S713 in FIG.

Next, the ultrasonic atomization type sterilizer 56 will be described with reference to FIGS. 61 to 63. FIG. 61 is a diagram showing an example of the installation position of the ultrasonic atomization type sterilizer 56b according to the fourth embodiment. The sterilizer 56b includes an ultrasonic atomizer 560b, a small blower 562, a light 7b, and a temperature / humidity sensor 561.

The ultrasonic atomizer 560b makes the disinfectant into a mist by the vibration of ultrasonic waves. The ultrasonic atomizer 560b is fixed to the ceiling 11 by the fixing member 151a. Further, the ultrasonic atomizer 560b is supported by the support member 151b. The tank for storing the sterilizing liquid is also located on the support member 151b.

Further, the mist generated from the ultrasonic atomizer 560b is pushed out by the air blown by the small blower 562, and is discharged horizontally along the bottom of the interior member 11b. The light 7b irradiates the mist emitted from between the support member 151b and the interior member 11b with visible light.

In the ultrasonic atomization type sterilizer 56b, the temperature / humidity sensor 561 is installed on the suction side of the small blower 562. As a result, the control unit 565 of the sterilization device 56b can detect the state of the air in front of the mist and adjust the spray amount of the mist. Further, the small blower 562 consumes less power than the car air conditioner 6. Therefore, the sterilizer 56b operates the small blower 562 during the spraying of the mist to reduce the retention of the mist.

FIG. 62 is a diagram showing another example of the configuration of the ultrasonic atomization type sterilizer 56b according to the fourth embodiment. As shown in FIG. 62, a liquid tank 563 for storing the sterilizing liquid is provided below the ultrasonic atomizer 560b. The control unit 565 of the sterilizer 56b controls the ultrasonic atomizer 560b, the small blower 562, the light 7b, and the car air conditioner 6.

FIG. 63 is a flowchart showing an example of the flow of the sterilization process by the ultrasonic atomization type sterilization device 56b according to the fourth embodiment.

The process from the process of determining whether or not the input of the start operation of S901 is accepted to the process of turning on the ventilation of the air conditioner of S908 is the same as that of S701 to S708 described with reference to FIG. 58.

Next, the control unit 565 of the sterilization device 56b turns on the small blower 562 and starts blowing air (S909).

Further, the control unit 565 turns on the ultrasonic atomizer 560b to start the generation of mist, and controls and turns on the light 7b (S910).

Next, the determination unit 5651 determines whether or not the scheduled spraying time has elapsed from the start of spraying (S911). The determination unit 5651 repeats the processes of S910 and S911 while it is determined that the scheduled spraying time has not elapsed (S911 "No").

Then, when the determination unit 5651 determines that the scheduled spraying time has elapsed (S911 “Yes”), the determination unit 5651 controls the ultrasonic atomizer 560b to stop the spraying of the mist and turn off the light 7b (S912). ..

After that, the control unit 565 turns off the small blower 562 and stops blowing (S913). Then, the determination unit 5651 controls the car air conditioner 6 to turn off the air conditioner (S914). If the car air conditioner 6 is not operated before spraying the mist, the processing of S914 is unnecessary. Then, the process returns to S901 and waits for the start of sterilization.

Further, the process of indicating that there is no remaining amount of the sterilizing solution in S915 is the same as the process of S713 in FIG.

As described above, the vehicle 1 of the present embodiment is provided above the lower side of the window 12 of the vehicle 1 and includes a sterilizing device 56 that sprays a liquid containing a sterilizing component into the vehicle interior 20. Therefore, according to the present embodiment, when the inside of the vehicle is sterilized with a liquid containing a sterilizing component, the sterilization can be efficiently performed with energy saving.

As mentioned above, when disinfecting the inside of a vehicle with a mist of disinfectant liquid, it is desirable that the mist particles are vaporized before reaching the dashboard 14 or the floor. In order to promote vaporization, it is effective to reduce the humidity in the air where the mist is ejected. Further, in general, the sterilization is preferably performed in an unmanned state of the vehicle 1, but when the car air conditioner 6 is driven at the time of sterilization, the charge amount of the battery is consumed. Therefore, it is desirable that the operation of the car air conditioner 6 can be reduced.

In the present embodiment, the mist is discharged from a position above the lower side of the window 12 of the vehicle 1 in which the temperature of the air becomes high in the passenger compartment 20, so that the mist particles reach the dashboard 14 or the floor. Easy to vaporize naturally.

Further, the vehicle 1 of the present embodiment includes

lights

7a and 7b that irradiate the mist sprayed from the sterilizing device 56 with visible light. Therefore, according to the vehicle 1 of the present embodiment, the user can easily grasp that the mist is sprayed.

Further, in the vehicle 1 of the present embodiment, the sterilizing device 56 is installed at a position higher than the midpoint in the vertical direction of the window 12. The humidity above the passenger compartment 20 tends to be lower because the temperature rises due to the influence of sunlight and the like. Therefore, the sterilizing device 56 is installed at a position higher than the midpoint in the vertical direction of the window 12, thereby facilitating the vaporization of mist.

Further, in the vehicle 1 of the present embodiment, the sterilization device 56 is installed on the ceiling 11 of the vehicle body 2. Since the ceiling 11 is at the highest position in the passenger compartment 20, it is possible to further facilitate the vaporization of mist particles before they reach the dashboard 14 or the floor.

Further, in the sterilizing device 56 of the vehicle 1 of the present embodiment, either a spray type method in which the sterilizing liquid is ejected in the form of mist or an ultrasonic atomization type method in which the sterilizing liquid is atomized by ultrasonic waves is adopted. You may.

Further, the fluid nozzle 560a of the sterilizing device 56 of the vehicle 1 of the present embodiment faces diagonally downward or horizontally. This allows the mist to be sprayed away from the dashboard 14 or the floor.

Further, the fluid nozzle 560a and the ultrasonic atomizer 560b of the disinfectant device 56 mounted on the vehicle 1 of the present embodiment are provided separately from the air outlet through which the car air conditioner 6 blows air into the vehicle interior 20. The air outlet of the car air conditioner 6 is generally provided in the center of the dashboard 14 or the like, but in the vehicle 1 of the present embodiment, the fluid nozzle 560a of the disinfectant device 56 is separated from the air outlet of the car air conditioner 6. And by providing the ultrasonic atomizer 560b above the window 12, the mist can be effectively vaporized.

Further, in the vehicle 1 of the present embodiment, when the humidity is equal to or higher than the first threshold value, the car air conditioner 6 is operated before the fluid nozzle 560a or the ultrasonic atomizer 560b sprays the disinfectant liquid. , Promotes the vaporization of mist.

Further, the vehicle 1 of the present embodiment can promote the vaporization of mist as needed while reducing the power consumption by properly using the heating and the ventilation of the car air conditioner 6 according to the humidity.
