Technical Field

The present invention relates to a vehicle and a vehicle interior cleaning device.

Background

Japanese patent application laid-open No. 2002-225540 (patent document 1) discloses a vehicle air conditioner including an inside air introduction mode and an outside air introduction mode, and describes a configuration in which the inside air introduction mode is interrupted and the outside air introduction mode is switched when an abnormality signal of the device is received during a cooling operation.

Disclosure of Invention

In the case of air conditioning by introducing indoor air as in patent document 1, the air in the vehicle interior is sucked by operating the blower.

However, the dust in the vehicle interior cannot be sufficiently removed by the output of the blower operated for introducing the interior air. On the other hand, when the output of the blower is increased, there is a possibility that the output may affect the occupant in the vehicle interior.

The present disclosure takes the above facts into consideration, and aims to obtain a vehicle and an interior cleaning device that remove dust in a vehicle interior without affecting occupants.

Means for solving the problems

The vehicle of the first aspect has: a communicating portion for communicating the interior of the vehicle with the exterior of the vehicle; a discharge device that is operated to discharge at least one of dust and liquid in the vehicle interior to the outside of the vehicle interior through the communication portion; and a control unit that operates the discharge device to discharge the dust in the vehicle interior to the outside of the vehicle interior when it is determined that there is no passenger in the vehicle interior.

In the vehicle according to the first aspect, the discharge device is operated, and at least one of dust and liquid in the vehicle interior is discharged to the outside of the vehicle interior through the communication portion that communicates the vehicle interior with the outside of the vehicle interior. Thus, the dust in the vehicle interior can be effectively removed only by operating the discharge device.

Further, the control unit operates the exhaust device when it is determined that there is no occupant in the vehicle interior. Thus, for example, even when the air in the vehicle interior is strongly sucked by the operation of the exhaust device, the occupant is not given an unpleasant feeling. The "communicating portion" referred to herein is not limited to a vent hole or the like formed in a vehicle interior, and is a concept that widely includes openable and closable portions such as a window and a sunroof of a vehicle.

A vehicle according to a second aspect is the vehicle according to the first aspect, wherein the exhaust device includes an air conditioner that takes in air inside or outside the vehicle interior and blows air into the vehicle interior.

In the vehicle according to the second aspect, the air conditioner can discharge dust in the vehicle interior to the outside of the vehicle interior.

A vehicle according to a third aspect is the vehicle according to the second aspect, wherein the control unit discharges dust in the vehicle interior to the outside of the vehicle interior with a force stronger than that during operation of the air conditioner.

In the vehicle according to the third aspect, the force at the time of discharge and the force at the time of discharge of dust in the case where the air conditioner is operated at the time of temperature adjustment in the vehicle interior are changed. This makes it possible to reliably discharge dust to the outside of the vehicle compartment when discharging dust.

In the vehicle according to the fourth aspect, in accordance with any one of the first to third aspects, the control unit may vibrate a vibration member provided in a seat during or before operation of the ejector.

In the vehicle according to the fourth aspect, the dust attached to the seat can be shaken off by vibrating the vibrating member during or before the operation of the ejector. This makes it possible to discharge the dust adhering to the seat to the outside of the vehicle compartment.

A fifth aspect of the vehicle according to any one of the first to fourth aspects, wherein the control unit includes a receiving unit that receives a signal from outside the vehicle, and the control unit operates the discharge device when the receiving unit receives a signal for cleaning from outside the vehicle.

In the vehicle according to the fifth aspect, the exhaust device operates when a signal to perform cleaning is received from outside the vehicle compartment. This makes it possible to clean the vehicle interior from outside the vehicle in a state where no occupant is present in the vehicle interior.

In the vehicle according to the sixth aspect, the control unit forcibly stops the discharge device when the control unit receives a signal for releasing the door lock or when the door is opened.

In the vehicle according to the sixth aspect, the control unit forcibly stops the discharge device when the door is opened. This makes it possible to reliably stop the discharge device before the user gets on the vehicle.

A seventh aspect of the vehicle is the vehicle according to any one of the first to sixth aspects, further comprising at least one of a sterilization device for sterilizing the vehicle interior and an insect-killing device for killing insects in the vehicle interior.

In the vehicle according to the seventh aspect, the environment in the vehicle interior can be favorably maintained by at least one of the sterilization device and the insect-killing device.

The eighth aspect of the vehicle is the seventh aspect of the vehicle, wherein the sterilizing device includes a germicidal lamp that irradiates a germicidal line into the vehicle interior by lighting.

In the vehicle according to the eighth aspect, the surfaces of the seats, the interior materials, and the like in the vehicle interior can be sterilized by lighting the germicidal lamp.

The vehicle interior cleaning device according to the ninth aspect is configured to be attachable from outside the vehicle to a communication portion that is provided in the vehicle and communicates the vehicle interior with the outside of the vehicle interior, and to discharge at least one of dust and liquid in the vehicle interior to the outside of the vehicle interior through the communication portion in a state where no occupant is present in the vehicle interior.

In the vehicle interior cleaning device according to the ninth aspect, at least one of dust and liquid in the vehicle interior is discharged to the outside of the vehicle interior through the communication portion. In this case, since the vehicle interior cleaning device is attached to the communication portion from the outside of the vehicle, it is not necessary to provide the vehicle with the cleaning device. Further, since at least one of dust and liquid is discharged to the outside of the vehicle compartment without an occupant, the occupant is not given an unpleasant feeling.

Effects of the invention

As described above, according to the vehicle and the vehicle interior cleaning device of the present invention, dust in the vehicle interior can be removed without affecting the occupant.

Detailed Description

< first embodiment >

A vehicle 10 according to a first embodiment will be described with reference to the drawings. The dimensional ratios in the drawings are exaggerated for convenience of description, and may be different from actual dimensional ratios.

As shown in fig. 1, a vehicle 10 of the present embodiment includes an interior cleaning unit 12. The vehicle interior cleaning unit 12 includes 4 fans, i.e., a first fan 14, a second fan 16, a third fan 18, and a fourth fan 20, as discharge devices, and a front seat vibrator 32 and a rear seat vibrator 34 as vibration members.

In the following description, the 4 blowers, i.e., the first blower 14, the second blower 16, the third blower 18, and the fourth blower 20, will be collectively referred to as "blowers" for short, without being distinguished from each other. Each blower is configured to operate by receiving electric power supply, and is electrically connected to an ECU (Electronic Control Unit) 38 as a Control Unit disposed in the front portion of the vehicle.

The first blower 14 is disposed inside an instrument panel 22 provided at the front part of the vehicle interior. Further, a first vent hole 22A as a communicating portion is formed in the instrument panel 22, and the vehicle interior and the vehicle exterior communicate with each other through the first vent hole 22A. And, the first blower 14 faces the first communication hole 22A. Therefore, when the first blower 14 is operated and the rotary blades of the first blower 14 are rotated in one direction, the air in the vehicle interior is discharged to the outside of the vehicle interior through the first ventilation hole 22A. In other words, air on the front side in the vehicle interior is drawn by the first blower 14.

The first blower 14 of the present embodiment is configured such that the rotary blades are rotatable in the opposite direction to one direction. The rotary blades of the first blower 14 rotate in the opposite direction, and air can be sent into the vehicle interior. Here, an air conditioner, not shown, is provided inside the instrument panel 22, and is configured to take in air inside or outside the vehicle interior and adjust the temperature of the air, and to blow air into the vehicle interior.

Second blower 16, third blower 18, and fourth blower 20 are disposed between floor panel 24 and under cover 26, and second blower 16 is located on the vehicle front side of front seat 28 in a plan view. In addition, second ventilation hole 24A, third ventilation hole 24B, and fourth ventilation hole 24C are formed as communication portions in floor panel 24, and second blower 16 faces second ventilation hole 24A formed in the front end portion of floor panel 24. Therefore, when the second blower 16 is operated and the rotary blades of the second blower 16 are rotated in one direction, the air in the vehicle interior is discharged to the outside of the vehicle interior through the second ventilation hole 24A. In other words, air on the front side in the vehicle interior is drawn by the second blower 16.

Third blower 18 is located between front seat 28 and rear seat 30 in a plan view, and faces third ventilation hole 24B formed in the vehicle longitudinal direction center portion of floor panel 24. Therefore, when the third blower 18 is operated and the rotary blades of the third blower 18 rotate in one direction, the air in the vehicle interior is discharged to the outside of the vehicle interior through the third ventilation hole 24B. In other words, air in the central portion in the front-rear direction of the vehicle interior is sucked by the third blower 18.

Fourth blower 20 is located on the vehicle rear side of rear seat 30 in plan view, and faces fourth through-air hole 24C formed in the vehicle front-rear direction center portion of floor panel 24. Therefore, when the fourth blower 20 is operated and the rotary blades of the fourth blower 20 rotate in one direction, the air in the vehicle interior is discharged to the outside of the vehicle interior through the fourth ventilation hole 24C. In other words, air on the rear side in the vehicle interior is drawn by the fourth blower 20.

As described above, the air discharged to the outside of the vehicle compartment by first blower 14, second blower 16, third blower 18, and fourth blower 20 flows to the vehicle rear side in the space between floor panel 24 and under cover 26 and is discharged to the outside from the rear of vehicle 10.

In the present embodiment, second blower 16, third blower 18, and fourth blower 20 are disposed in the space between floor panel 24 and bottom cover 26, but the present invention is not limited thereto. For example, second blower 16, third blower 18, and fourth blower 20 may be mounted on the lower surface of floor 24 at a location where bottom cover 26 is not present. In this case, the air in the vehicle interior is directly discharged to the outside of the vehicle 10 by the second blower 16, the third blower 18, and the fourth blower 20.

In the present embodiment, the second ventilation hole 24A, the third ventilation hole 24B, and the fourth ventilation hole 24C may be configured to be closable by a cover or the like, not shown. In this case, the second vent hole 24A, the third vent hole 24B, and the fourth vent hole 24C may be opened only when air in the vehicle interior is discharged.

A front seat vibrator 32 is mounted inside the seat back 28A of the front seat 28. The front seat vibrator 32 is configured to vibrate by operation to vibrate the entire seat back 28A, and is configured to massage an occupant seated in the front seat 28. Further, the front seat vibrating member 32 is configured to vibrate away dust adhering to the seat back 28A in a state where no occupant is seated on the front seat 28.

On the other hand, a rear seat vibrator 34 is mounted inside the seat back 30A of the rear seat 30. The rear seat vibrator 34 is configured to vibrate by the operation to vibrate the entire seat back 30A, and is configured to massage the occupant seated in the rear seat 30. Further, the rear seat vibrating member 34 is configured to vibrate the dust attached to the seat back 30A in a state where no occupant is seated on the rear seat 30. Front seat vibrator 32 and rear seat vibrator 34 are electrically connected to ECU38, and are operated by signals from ECU 38.

Here, an indoor camera 36 is disposed at the front end of a ceiling portion in the vehicle interior. The indoor camera 36 is directed toward the vehicle rear side and the vehicle lower side, and the entire vehicle interior can be imaged by the indoor camera 36.

(hardware configuration of vehicle 10)

Fig. 2 is a block diagram showing the hardware configuration of the vehicle 10. As shown in fig. 2, the vehicle 10 includes a CPU (Central Processing Unit) 40, a ROM (Read Only Memory) 42, a RAM (Random Access Memory) 44, a storage device 46, a communication interface 48, and an input/output interface 50. The respective components are connected to each other via a bus 51 so as to be able to communicate with each other.

The CPU40 is a central processing unit that executes various programs to control the respective units. That is, the CPU40 reads out a program from the ROM42 or the storage device 46, and executes the program with the RAM44 as a work area. The CPU40 performs control of the above-described configurations and various arithmetic processes in accordance with programs recorded in the ROM42 or the storage device 46.

The ROM42 stores various programs and various data. The RAM44 temporarily stores programs and data as a work area. The storage device 46 is constituted by an HDD (Hard Disk Drive) or an SSD (Solid State Drive), and stores various programs including an operating system and various data. In the present embodiment, a vehicle interior cleaning program or the like for cleaning the vehicle interior is stored in the ROM42 or the storage device 46.

The communication interface 48 is an interface for the vehicle 10 to communicate with an external device, and for example, standards such as ethernet (registered trademark), FDDI, and Wi-Fi (registered trademark) are used.

The input/output interface 50 is connected to the indoor camera 36, the first blower 14, the second blower 16, the third blower 18, the fourth blower 20, the front seat vibrating member 32, and the rear seat vibrating member 34. The indoor camera 36 is configured to capture an image of the inside of the vehicle upon receiving a signal from the vehicle 10, and in the present embodiment, the image of the inside of the vehicle is captured while the power of the vehicle 10 is turned on, for example.

(functional structure of vehicle 10)

The vehicle 10 uses the hardware resources described above to implement various functions. The functional configuration realized by the vehicle 10 will be described with reference to fig. 3.

As shown in fig. 3, the vehicle 10 includes an inside air circulation unit 52, an occupant presence determining unit 54, a seat vibrating unit 56, a dust discharging unit 58, and a forcible stopping unit 60 as functional configurations. The functional configurations are realized by the CPU40 reading out and executing a program stored in the ROM42 or the storage device 46.

The inside air circulating portion 52 circulates air in the vehicle interior. Specifically, the inside air circulation unit 52 causes air in the vehicle interior to be introduced into the air conditioning apparatus, not shown, by operating at least 1 of the first blower 14, the second blower 16, the third blower 18, and the fourth blower 20. Then, the air whose temperature has been adjusted by the air conditioner is again sent into the vehicle interior, thereby circulating the air in the vehicle interior.

The occupant presence/absence determination unit 54 detects the presence/absence of an occupant in the vehicle interior. Specifically, the occupant presence determination unit 54 analyzes based on the image captured by the indoor camera 36, and determines that an occupant is present in the vehicle interior when the occupant is detected. The occupant presence determination unit 54 analyzes the image captured by the indoor camera 36, and determines that an occupant is not present in the vehicle interior when the occupant is not detected.

The seat vibrating portion 56 vibrates the front seat 28 and the rear seat 30. Specifically, the front seat vibrating member 32 of the front seat 28 and the rear seat vibrating member 34 of the rear seat 30 are vibrated when the first blower 14, the second blower 16, the third blower 18, and the fourth blower 20 are operated or before the respective blowers are operated by the function of the dust discharging unit 58 described later. By vibrating front seat vibrator 32 and rear seat vibrator 34 in this way, front seat 28 and rear seat 30 are vibrated. In the present embodiment, a mode is provided in which the occupants seated in the front seat 28 and the rear seat 30 are massaged, respectively, and the seat vibrating portion 56 vibrates the front seat vibrator 32 and the rear seat vibrator 34 with a larger output than in the massage mode.

The dust discharge unit 58 operates the first, second, third, and fourth blowers 14, 16, 18, and 20 to suck air in the vehicle interior and discharge dust in the vehicle interior to the outside of the vehicle interior. At this time, the outputs when the first blower 14, the second blower 16, the third blower 18, and the fourth blower 20 are operated are set to be larger than the outputs when the blowers are operated by the internal air circulation unit 52. That is, the dust in the vehicle interior is discharged to the outside of the vehicle interior by sucking the air in the vehicle interior with a force stronger than that in the case where each blower is operated by the inside air circulating portion 52. In other words, the internal air circulation portion 52 operates each blower with an output smaller than an output operated by the dust discharge portion 58. The dust discharge unit 58 operates each blower when the occupant presence determination unit 54 determines that there is no occupant in the vehicle interior.

The forcible stop unit 60 forcibly stops each blower operated by the dust discharge unit 58 when a signal for releasing the door lock of the vehicle 10 is received or when the door is opened. Specifically, when first blower 14, second blower 16, third blower 18, and fourth blower 20 are operating due to the function of dust ejector 58 in a state where no occupant is present in the vehicle interior, each blower is forcibly stopped when a signal for releasing the door lock is received from the outside of vehicle 10. That is, even in a state in which dust is being discharged, the supply of electric power to each blower is stopped.

(action)

Next, the operation of the present embodiment will be described.

(an example of cleaning treatment in a vehicle interior)

Fig. 4 is a flowchart illustrating an example of the flow of the vehicle interior cleaning process of the vehicle 10. The vehicle interior cleaning process is executed by the CPU40 reading the vehicle interior cleaning program from the ROM42 or the storage device 46, and expanding and executing the vehicle interior cleaning program into the RAM 44. The vehicle interior cleaning process is periodically performed at predetermined intervals.

As shown in fig. 4, the CPU40 determines in step S102 whether the cleaning mode is on. For example, an unillustrated operation panel provided on the instrument panel 22 is provided with a button for switching the cleaning mode on and off, and the cleaning mode is switched by the occupant operating the button.

When the cleaning mode is set to on, it is determined in step S102 that the cleaning mode is on. On the other hand, when the cleaning mode is set to off, it is determined in step S102 that the cleaning mode is off. The cleaning mode may be switched by an operation method other than a button. For example, the cleaning mode may be displayed on a touch panel type center display, and the cleaning mode may be switched by the occupant touching the center display. In addition, the cleaning mode can be switched by the voice uttered by the occupant.

If the cleaning mode is on in step S102, the CPU40 proceeds to the process of step S104. If the cleaning mode is not on in step S102, that is, if the cleaning mode is off, CPU40 ends the vehicle interior cleaning process without cleaning the vehicle interior.

The CPU40 determines in step S104 whether or not there is no occupant in the vehicle interior. Specifically, the CPU40 determines the presence or absence of an occupant using image data captured by the indoor camera 36 by the function of the occupant presence determining unit 54. When determining that there is no occupant in the vehicle interior, the CPU40 proceeds to the process of step S106. If the CPU40 determines in step S104 that the occupant is present in the vehicle interior, the vehicle interior cleaning process is terminated without cleaning the vehicle interior.

The CPU40 starts cleaning the vehicle interior in step S106. Specifically, the CPU40 operates the first blower 14, the second blower 16, the third blower 18, and the fourth blower 20 by the function of the dust discharge unit 58 to draw air in the vehicle interior. At this time, each blower is operated at an output to such an extent that dust in the vehicle interior can be sucked.

In step S106, the CPU40 causes the front seat vibrator 32 mounted in the seat back 28A of the front seat 28 and the rear seat vibrator 34 mounted in the seat back 30A of the rear seat 30 to vibrate by the function of the seat vibrating portion 56. The timing for vibrating the front seat vibrator 32 and the rear seat vibrator 34 is when each blower is operated or before each blower is operated.

Next, the CPU40 determines in step S108 whether or not a predetermined time has elapsed. The predetermined time is a time sufficient for cleaning the vehicle interior, and the CPU40 starts a timer after the start of cleaning in step S106 to measure the time. When determining that the predetermined time has elapsed, the CPU40 proceeds to the process of step S114.

The CPU40 ends the cleaning in step S114. That is, CPU40 stops first blower 14, second blower 16, third blower 18, and fourth blower 20. Further, the CPU40 stops the front seat vibrator 32 and the rear seat vibrator 34. Then, the CPU40 ends the vehicle interior cleaning process.

On the other hand, when the CPU40 determines in step S108 that the predetermined time has not elapsed, the process proceeds to step S110, and it is determined whether or not the door lock of the vehicle 10 has been released. When receiving a signal for releasing the door lock from the outside of the vehicle, the CPU40 determines that the door lock of the vehicle 10 is released and proceeds to the process of step S112. When the CPU40 determines in step S110 that the door lock has not been released, the process proceeds to step S108, and the CPU repeatedly determines whether or not a predetermined time has elapsed.

The CPU40 forcibly stops the cleaning in step S112. Specifically, CPU40 forces stop unit 60 to function to stop the supply of electric power to first blower 14, second blower 16, third blower 18, and fourth blower 20. Further, the CPU40 stops the supply of electric power to the front seat vibrator 32 and the rear seat vibrator 34. At this time, the rotation of each blower may be locked by a lock mechanism or the like. That is, even when the supply of electric power to each blower is stopped, each blower rotates by inertia, and therefore the rotation can be forcibly locked. Then, the CPU40 ends the vehicle interior cleaning process.

As described above, in the vehicle 10 of the present embodiment, when the occupant presence determining unit 54 determines that there is no occupant in the vehicle interior, each blower is operated to suck air in the vehicle interior and to discharge dust to the outside of the vehicle interior. By thus discharging the dust to the outside of the vehicle interior when it is determined that there is no passenger in the vehicle interior, the dust in the vehicle interior can be discharged to the outside of the vehicle interior without giving an unpleasant feeling to the passenger.

In the present embodiment, since the respective blowers are operated to discharge dust to the outside of the vehicle, blowers used for other applications such as air conditioners can be used, and a dedicated cleaning device is not required. For example, in fig. 1, the first blower 14 can draw and circulate air in the vehicle interior by reducing the output compared to the case of drawing dust. This allows both the introduction of the interior air and the suction of the dust to be performed by 1 blower. That is, dust in the vehicle interior can be removed at low cost.

In the present embodiment, dust adhering to the front seat 28 and the rear seat 30 can be shaken off by vibrating the front seat vibrating element 32 and the rear seat vibrating element 34 during or before the operation of each blower. This enables dust in the vehicle interior to be effectively removed.

In the present embodiment, each blower is forcibly stopped by the forcible stop unit 60 when the door is opened. This makes it possible to reliably stop the blower in front of the passenger, and to reduce the influence of the dust discharge portion on the passenger.

< second embodiment >

Next, a vehicle 70 according to a second embodiment will be described with reference to fig. 5 to 7. The same components as those of the first embodiment are denoted by the same reference numerals, and description thereof is omitted as appropriate.

As shown in fig. 5, an interior cleaning unit 71 mounted on a vehicle 70 of the present embodiment includes a germicidal lamp 72 as an example of a germicidal device in addition to the interior cleaning unit 12 of the first embodiment. In the present embodiment, as an example, the germicidal lamps 72 are provided at the front and rear of the ceiling portion in the vehicle interior. The germicidal lamp 72 is configured to include a lamp that irradiates light rays (germicidal rays) having a wavelength band of germicidal power, and in the present embodiment, a UV lamp (i.e., an ultraviolet irradiation lamp) is used. Then, the germicidal lamp 72 is turned on to irradiate germicidal lines into the vehicle interior.

(hardware configuration of vehicle 70)

Fig. 6 is a block diagram showing the hardware structure of the vehicle 70. As shown in fig. 6, the vehicle 70 includes a CPU40, a ROM42, a RAM44, a storage device 46, a communication interface 48, and an input/output interface 50. A germicidal lamp 72(UV lamp) is connected to the input/output interface 50 of the present embodiment.

(functional structure of vehicle 70)

As shown in fig. 7, the vehicle 70 includes the inside air circulation unit 52, the occupant presence determining unit 54, the seat vibrating unit 56, the dust discharging unit 58, the radiation unit 74, and the forcible suspension unit 60 as functional configurations. The functional configurations are realized by the CPU40 reading out and executing a program stored in the ROM42 or the storage device 46.

When the occupant presence determining unit 54 determines that there is no occupant in the vehicle interior, the germicidal line irradiating unit 74 irradiates germicidal lines into the vehicle interior by turning on the germicidal lamp 72 in the vehicle interior. Other functional configurations are the same as those of the first embodiment.

(action)

Next, the operation of the present embodiment will be described.

(an example of cleaning treatment in a vehicle interior)

The flow of the vehicle interior cleaning process of the vehicle 70 is the same as the flow chart shown in fig. 4, as in the first embodiment. The vehicle interior cleaning process is executed by the CPU40 reading the vehicle interior cleaning program from the ROM42 or the storage device 46, and expanding and executing the vehicle interior cleaning program into the RAM 44. The vehicle interior cleaning process is periodically performed at predetermined intervals.

Here, in the present embodiment, when the CPU40 starts cleaning in step S106, the respective blowers, the front seat vibrator 32, and the rear seat vibrator 34 are operated by the functions of the dust discharge portion 58 and the seat vibrator 56. In the present embodiment, the sterilizing lamps 72 in the front and rear are turned on by the function of the sterilizing-ray irradiating section 74 to irradiate the inside of the vehicle compartment with the sterilizing rays.

As described above, in the present embodiment, by lighting the germicidal lamp 72, the front seat 28, the rear seat 30, the interior parts, and the like in the vehicle interior can be sterilized, and the environment in the vehicle interior can be maintained more favorably.

< third embodiment >

Next, a vehicle interior cleaning device 80 according to a third embodiment will be described with reference to fig. 8. The same components as those of the first embodiment are denoted by the same reference numerals, and description thereof is omitted as appropriate.

As shown in fig. 8, the vehicle interior cleaning device 80 of the present embodiment is configured to be attachable to a vehicle 82. Specifically, a vent hole 84A as a communicating portion is formed in a center portion in the vehicle front-rear direction in a floor panel 84 of the vehicle 82.

The exhaust hole 84A is formed through the floor 84 so as to communicate between the inside and the outside of the vehicle. The exhaust hole 84A is configured to be openable and closable by the lid member 86, and fig. 8 shows a state in which the lid member 86 is open and the exhaust hole 84A is open. In the present embodiment, the lid member 86 and the floor 84 are configured to be coplanar with each other in a state where the lid member 86 is closed, for example.

Here, an interior cleaning device 80 is attached to the lower surface of the floor 84 from the outside of the vehicle 82, and the interior cleaning device 80 includes an exhaust portion 88 and a duct portion 90. The exhaust portion 88 is formed in a substantially cylindrical shape, and a vehicle exterior blower 88A is disposed inside the exhaust portion 88. Further, a sealing member, not shown, is provided on the upper surface of the exhaust portion 88, and the gap between the exhaust portion 88 and the floor 84 is sealed by pressing the sealing member against the lower surface of the floor 84.

One end of the duct portion 90 is connected to the lower surface of the exhaust portion 88, and the other end extends from the exhaust portion 88 to the outside of the vehicle. In the present embodiment, the other end side of the tunnel portion 90 extends from the exhaust portion 88 toward the vehicle rear side, and is connected to a not-shown dust collecting portion, for example.

Here, in the present embodiment, first blower 14 is configured to be operated during operation of vehicle exterior blower 88A or before operation of vehicle exterior blower 88A, as an example. Thus, air is blown into the vehicle interior through the first ventilation hole 22A.

(action)

Next, the operation of the present embodiment will be described.

In the vehicle interior cleaning device 80 of the present embodiment, the external air blower 88A is operated in a state where the vehicle interior cleaning device 80 is mounted on the vehicle 82, and dust in the vehicle interior is discharged to the outside of the vehicle interior through the exhaust hole 84A. That is, the dust flows in the passage portion 90 and is conveyed toward the dust collecting portion. Since the vehicle interior cleaning device 80 is mounted from the outside of the vehicle 82 in this manner, it is not necessary to separately provide a cleaning device on the vehicle 82.

In addition, in the present embodiment, since air can be sucked by the outside air blower 88A while air is blown into the vehicle interior from the first air blower 14, an air flow can be generated in the vehicle interior, and dust can be discharged more efficiently.

Although the first to third embodiments have been described above, it is needless to say that the present invention can be implemented in various ways without departing from the scope of the present invention. For example, in the above-described embodiment, the cleaning is performed when there is no occupant in the vehicle interior in a state where the cleaning mode is set to on in advance, but the cleaning is not limited to this, and may be performed by another method.

As an example of a method for cleaning the vehicle interior, a configuration may be adopted in which the user transmits a signal for cleaning from the outside of the vehicle to the vehicle 10. For example, the cleaning in the vehicle interior may be instructed by operating a remote control key carried by a user of the vehicle 10. In this case, a receiving unit that receives a signal from the outside of the vehicle 10 may be provided. Then, the communication interface 48 of the ECU38 receives a signal from the key fob by the function of the receiving unit, and when it is determined that there is no occupant in the vehicle interior by the function of the occupant presence determining unit 54, cleaning is started. That is, each blower is operated by the function of the dust discharge portion 58. Further, the front seat vibrator 32 and the rear seat vibrator 34 may be vibrated by the function of the seat vibrating portion 56. At this time, when the door of the vehicle 10 is not locked, the door may be locked before the cleaning is started.

In the above embodiment, 4 blowers, that is, the first blower 14, the second blower 16, the third blower 18, and the fourth blower 20, are operated to suck air in the vehicle interior, but the number of blowers is not particularly limited. For example, only the first blower 14 may be provided, and only 1 blower may be used to suck the air in the vehicle interior. In addition, the reverse configuration may be provided with 5 or more blowers. Further, the position of each blower is not limited. For example, a blower may be provided on the ceiling portion to draw air toward the vehicle upper side.

In the above embodiment, the first ventilation hole 22A, the second ventilation hole 24A, the third ventilation hole 24B, and the fourth ventilation hole 24C are communication portions, but the present invention is not limited thereto. For example, a window, a sunroof, or the like of the vehicle 10 may be used as the communicating portion. In this case, the dust in the vehicle interior can be discharged by attaching and operating the discharge device from the outside of the vehicle 10 in a state where the window, the sunroof, and the like are opened. Further, the dust in the vehicle interior may be discharged to the outside of the vehicle interior together with the air in the vehicle interior by making the vehicle interior have a positive pressure.

In the above-described embodiment, the structure for sucking air in the vehicle interior has been described, but the present invention is not limited to this. That is, a discharge device capable of discharging at least one of dust and liquid to the outside of the vehicle compartment may be used. For example, a discharge device such as a suction pump may be used instead of the blower. In this case, by operating the suction pump after the interior of the vehicle is washed with water, the water in the interior of the vehicle can be discharged (drained) to the exterior of the vehicle. Further, a nozzle for spraying water such as a sprinkler may be provided on the ceiling portion in the vehicle interior, and after water is sprayed from the nozzle into the vehicle interior, the suction pump may be operated to discharge the water.

In the first and second embodiments, the dust in the vehicle interior is removed by the blower that operates when the air in the vehicle interior is circulated by the interior air circulating portion 52, but the present invention is not limited to this. For example, the dust in the vehicle interior may be removed by another blower mounted on the vehicle 10. In these cases, as in the above-described embodiment, the blower is operated at a higher output than that in normal use in a state where the occupant is not present in the vehicle interior, thereby removing dust in the vehicle interior.

In the above embodiment, the front seat vibrator 32 is mounted on the seat back 28A of the front seat 28, and the rear seat vibrator 34 is mounted on the seat back 30A of the rear seat 30. For example, a seat cushion and a headrest of the front seat 28 may be provided with a vibration member similar to the front seat vibration member 32.

Further, a cleaning device for cleaning the floor 24 may be provided in addition to the above-described structure. For example, a cleaning device that takes in dust while autonomously traveling on the floor 24 may be provided. In this case, the dust on the floor 24 can be efficiently removed by taking in the dust by the cleaning device after the dust in the vehicle interior is moved downward by operating the first blower 14, the second blower 16, the third blower 18, and the fourth blower 20 by the function of the dust discharge portion 58.

In the above embodiment, the occupant presence determination unit determines the presence of an occupant based on the image captured by the indoor camera 36, but the present invention is not limited to this. For example, a seating sensor may be provided in each seat, and when it is determined that no occupant is seated in all the seats based on signals from the seating sensors, it may be determined that no occupant is present in the vehicle interior. Further, other sensors may be provided in each seat, and the presence or absence of the occupant may be determined by these sensors.

In the third embodiment, the exhaust hole 84A is formed in the floor 84, and the vehicle interior cleaning device 80 is attached to the portion where the exhaust hole 84A is formed. For example, an exhaust hole may be formed in the ceiling portion of vehicle 82, and an interior cleaning device may be attached to the ceiling portion from above vehicle 82. In such a case, an unmanned aerial vehicle such as an unmanned aerial vehicle having an exhaust function may be used.

In the second embodiment, the bactericidal lamp 72 is turned on to sterilize the front seat 28, the rear seat 30, the interior, and the like in the vehicle interior, but the present invention is not limited thereto, and other bactericidal devices may be used. For example, the sterilization device may be configured to include a sterilization spray for spraying a sterilization agent. In addition, the vehicle may be provided with an insect-killing device for killing insects in the vehicle interior in place of or in addition to the sterilization device.

In the above-described embodiment, the in-vehicle cleaning process executed by the CPU40 by reading software (program) may be executed by various processors other than the CPU. Examples of the processor in this case include a dedicated Circuit or the like having a Circuit configuration designed specifically for executing a Specific process, such as a PLD (Programmable Logic Device) or an ASIC (Application Specific Integrated Circuit) whose Circuit configuration can be changed after manufacture, such as an FPGA (Field-Programmable Gate Array). The vehicle interior cleaning process may be executed by 1 of these various processors, or may be executed by a combination of 2 or more processors of the same or different kind (for example, a plurality of FPGAs, a combination of a CPU and an FPGA, or the like). The hardware structure of these various processors is, more specifically, a circuit in which circuit elements such as semiconductor elements are combined.

In the above embodiment, the storage device 46 is a recording unit, but is not limited to this. For example, a recording medium such as a CD (Compact disc), a DVD (Digital Versatile disc), or a USB (Universal Serial Bus) memory may be used as the recording unit. In this case, various programs are stored in these recording media.
