Description

The present invention relates to an air conditioner that performs air conditioning near an occupant seated in a seat in the passenger compartment of a vehicle such as an automobile.

In a vehicle such as an automobile, an air conditioner for the passenger compartment is used to heat or cool the passenger compartment in which an occupant including a driver rides.
Further, in an automobile exposed to direct sunlight, in order to heat or cool the interior of the vehicle, it is common to use an air conditioner in the vehicle interior, which has higher performance than the space.
As a result, it is necessary to use a large amount of electric power to operate the compressor of the vehicle interior air conditioner.
This has a direct effect on fuel efficiency in automobiles that use electricity as power. (Patent Documents 1 and 2)

JP-A-57-205212 Japanese Unexamined Patent Publication No. 58-022709

However, even if such a high-performance vehicle interior air conditioner is used, the outlet of the air-conditioned air to the vehicle interior is limited to the back side or the upper part of the dashboard. In Patent Documents 1 and 2, only the outlet of the vehicle interior air conditioner is added on the upper side of the steering column.
For this reason, it is difficult to cool the occupant, for example, the thigh, which is seated on the seat, by directly applying the air flow blown from the passenger compartment air conditioner.
In particular, in the case of the rear seat, it is common that the outlet is provided only at a low position such as the outlet on the floor surface provided under the front seat or the outlet on the rear surface of the center console. It is harder to cool than the front seat. Unless the temperature of the passenger compartment becomes an appropriate temperature as a whole, it may not be possible to appropriately cool the occupant seated on the seat, for example, the thigh.

Moreover, since the passenger compartment air conditioner controls the temperature of the passenger compartment space to be an appropriate temperature as a whole, it is suitable even if the air conditioning is advanced around the occupant seated on the seat. There may be places where it is difficult to control the temperature.
For example, it is difficult to control the temperature around the thigh that comes into contact with the seat surface.
Further, in the rear seat, it is difficult to make the temperature around the seated occupant uniform to a suitable temperature as a whole.

As described above, in the vehicle, it is required to equalize the temperature around the occupant seated on the seat to improve the comfort of the occupant.

The vehicle air-conditioning device according to the present invention is provided around a seat on which an occupant in the passenger compartment of the vehicle sits, and the openings at both ends are located in the passenger compartment and air inside the passageway. The forced air blower has a forced air blower, and the forced air blower repeatedly changes the flow direction of air in the communication passage during continuous operation.

Preferably, the forced blower device repeatedly reverses the flow direction of air in the communication passage during continuous operation.

It is preferable that the communication passage is provided along the vertical direction in the vehicle interior, and one of the openings is provided so as to be displaced higher than the other opening.

Preferably, one of the openings is provided near the floor surface in the vehicle interior, and the other opening is provided at least at a position higher than the seat surface of the seat.

Preferably, the aisle is provided so that the opening on the upper side faces the seat on the rear side in the seat on the front side among the plurality of seats arranged in the front and rear in the vehicle interior.

Preferably, the aisle is provided on the dashboard in the passenger compartment so that the upper opening faces the seat in the front row in the passenger compartment.

Preferably, when the heating of the passenger compartment is started, the forced blower measures the time or amount of air sucked from the lower opening to be discharged from the upper opening from the upper opening. It is preferable to make the inhaled air larger than the time or amount to be discharged from the lower opening, and to reduce the difference in time or amount between the two when the heating in the vehicle interior is advanced.

Preferably, the forced air blower sets the time or amount of air sucked in from the upper opening to be discharged from the lower opening when the cooling of the passenger compartment is started. It is preferable to make the air sucked in from the air larger than the time or amount to be discharged from the opening on the upper side, and to reduce the difference in time or amount between the two when the cooling in the passenger compartment is advanced.

Preferably, it is preferable to have a partition member for partitioning the passenger compartment up and down on the upper side of the opening on the upper side.

In the present invention, a continuous passage is provided around a seat on which an occupant in the passenger compartment of the vehicle is seated, and the openings at both ends of the continuous passage are located in the passenger compartment. Then, the forced air blower that allows air to flow inside the communication passage repeatedly changes the flow direction of the air in the communication passage during continuous operation. For example, the flow direction is repeatedly reversed.
Therefore, an air flow whose flow direction changes repeatedly is supplied at a location around the sheet to which the air flow from the communication passage is supplied. Thereby, the temperature around the seat to which the air flow from the communication passage is supplied can be appropriately adjusted. Crew comfort can be improved.
On the other hand, when an air flow in a constant direction is always supplied, a constant air flow continues to be generated at the portion corresponding to the opening, so that the air flow may be excessively heated or cooled over time. In this case, the airflow can improve the initial comfort, but in the long run local heating or cooling will occur and the comfort of the occupant will be impaired.
Further, since both ends of the continuous passage are located in the vehicle interior, only the air in the vehicle interior is circulated. Therefore, the temperature around the occupant seated on the seat can be leveled or made uniform to a suitable temperature without impairing the air conditioning function of the entire vehicle interior by the vehicle interior air conditioner.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[First Embodiment]
FIG. 1 is a schematic explanatory view of an automobile 1 according to the first embodiment of the present invention.

The vehicle body of the automobile 1 of FIG. 1 has a passenger compartment 2 on which an occupant rides, and front chambers 3 and rear chambers 4 arranged in front of and behind the passenger compartment 2. In the passenger compartment 2, seats 5 on which the occupants are seated are provided in two rows in the front and rear. Further, a dashboard 6 is provided in front of the front right seat 5.

FIG. 2 is an explanatory diagram of a main part configuration of the vehicle interior air conditioner 10 of FIG.

The vehicle interior air conditioner 10 of FIG. 2 includes a temperature sensor 11, a solar radiation sensor 12, a humidity sensor 13, an vehicle interior air conditioning control unit 14, a blower fan 15, a compressor 16, an evaporator 17, a heater 18, and an air conditioning duct 19.
The temperature sensor 11 detects the temperature of the vehicle interior 2.
The solar radiation sensor 12 detects the amount of solar radiation emitted to the vehicle interior 2 through the window glass.
The humidity sensor 13 detects the temperature of the vehicle interior 2.
The compressor 16 is connected to an evaporator 17 and a capacitor (not shown), and a refrigerant is circulated between them.
The blower fan 15, the evaporator 17, and the heater 18 are arranged in the air conditioning duct 19 leading to the vehicle interior 2. For example, the air conditioning duct 19 takes in air from outside the vehicle interior 2 and exhausts air into the vehicle from the air outlet 20 at the upper part of the dashboard 6 and the air outlet 20 at the lower side of the dashboard 6 as shown in FIG.
The blower fan 15 creates an air flow in the air conditioning duct 19.
The evaporator 17 is cooled by the refrigerant and cools the air passing through the air conditioning duct 19.
The heater 18 heats the air passing through the air conditioning duct 19.
A temperature sensor 11, an illuminance sensor 12, a humidity sensor 13, a blower fan 15, a compressor 16, and a heater 18 are connected to the vehicle interior air conditioning control unit 14.
The vehicle interior air conditioning control unit 14 controls the operations of the blower fan 15, the compressor 16, and the heater 18 according to the relationship between the values detected by the temperature sensor 11, the solar radiation sensor 12, and the humidity sensor 13 and the control target value.
As a result, the vehicle interior air conditioner 10 can blow out the heated or cooled air flow from the outlet 20 of the air conditioning duct 19 to the vehicle interior 2. Then, for example, the overall temperature of the vehicle interior 2 is controlled so that the detected temperature of the vehicle interior 2 becomes the target temperature.

By the way, by providing such a vehicle interior air conditioner 10, the temperature of the vehicle interior 2 can be appropriately adjusted.
In particular, in an automobile 1 exposed to direct sunlight, in order to heat or cool the passenger compartment 2, it is common that a passenger compartment air conditioner 10 having higher performance than the space is used.
As a result, it is necessary to use a large amount of electric power or the like to operate the compressor 16 or the like of the vehicle interior air conditioner 10. This directly affects the fuel efficiency performance of, for example, the automobile 1 that uses electricity as power.
However, even if such a high-performance vehicle interior air conditioner 10 is used, the outlet 20 for the air-conditioned air to the vehicle interior 2 is limited to the back side or the upper part of the dashboard 6.
Therefore, it is difficult to cool the occupant, for example, the thigh, which is seated on the seat 5, by directly applying the air flow blown from the vehicle interior air conditioner 10.
Unless the temperature of the passenger compartment 2 becomes an appropriate temperature as a whole, it may not be possible to adequately cool, for example, the thighs of an occupant seated on the seat 5.
In particular, in the rear seat 5, only the outlet 20 at a low position such as the outlet 20 on the floor surface provided under the seat 5 on the front side and the outlet 20 on the rear surface of the center console 7 is provided. Is common, and it is harder to cool than the front seat 5.

Moreover, since the vehicle interior air conditioner 10 controls the temperature of the space of the vehicle interior 2 so as to be an appropriate temperature as a whole, the air conditioning is advanced around the occupant seated on the seat 5. However, there may be places where it is difficult to control the temperature to a suitable temperature.
For example, it is difficult to control the temperature around the thigh that comes into contact with the seat surface.
Further, in the rear seat 5, it is difficult to make the temperature around the seated occupant uniform to a suitable temperature as a whole.

As described above, in the automobile 1, it is required to make the temperature around the occupant seated on the seat 5 uniform to improve the comfort of the occupant.

FIG. 3 is an explanatory diagram of a main part configuration of the individual air conditioner 30 according to the first embodiment.

The individual air conditioner 30 of FIG. 3 has a communication passage 34 having openings formed at both ends, a forced air blower 35, and a control unit 38. Further, FIG. 3 illustrates the temperature sensor 11, the solar radiation sensor 12, the humidity sensor 13, the vehicle interior air conditioning control unit 14, and the timer 39 of the vehicle interior air conditioning device 10. The individual air conditioner 30 may have its own temperature sensor 11, illuminance sensor 12, and humidity sensor 13.
A center console 7 is shown next to the seat 5 in the front row. An outlet 20 is formed on the rear surface of the center console 7.

The communication passage 34 is provided around the seat 5 on which the occupant in the passenger compartment 2 is seated so that the openings at both ends thereof are located in the passenger compartment 2.
In the present embodiment, the communication passage 34 is provided along the vertical direction on the back surface portion of the front seat 5. As a result, the upper opening 32 is provided at a position higher than the lower opening 33.

The lower opening 33 opens on the lower surface of the seat portion of the front seat 5. As a result, the lower opening 33 opens near the floor surface of the vehicle interior 2.
The upper opening 32 opens to the rear surface of the back portion of the front seat 5. As a result, the upper opening 32 is provided so as to face the rear seat 5 at a position higher than the seating surface of the rear seat 5.
As a result, the communication passage 34 communicates between the lower side of the seat portion of the front seat 5 and the rear side of the back portion of the front seat 5, and the air in the passenger compartment 2 is allowed to flow between them. Become.

The forced air blower 35 is provided in the central portion of the communication passage 34. By rotating, for example, a fan of the forced air blower 35, an air flow is generated inside the communication passage 34. The air in the vehicle is taken into the communication passage 34 from one of the lower opening 33 and the upper opening 32 according to the forward and reverse rotation directions of the fan of the forced blower 35, and is exhausted from the other.

A temperature sensor 11, a solar radiation sensor 12, a humidity sensor 13, a vehicle interior air conditioning control unit 14, a timer 39, and a forced air blower 35 are connected to the control unit 38.
Then, the control unit 38 controls the operation of the forced ventilation device 35 according to the temperature, humidity, amount of solar radiation, operating time, and the operating state of the vehicle interior air conditioner 10.
Specifically, for example, the control unit 38 controls the operation of the forced blower device 35 so as to repeatedly reverse the flow direction of the air in the communication passage 34 during continuous operation.

FIG. 4 is a control flowchart showing an example of reverse operation in the flow direction during heating.
The control unit 38 starts the process of FIG. 4, for example, when the vehicle interior air conditioner 10 starts the heating operation.
The control unit 38 may determine the start of the heating operation based on, for example, the air conditioning state information from the vehicle interior air conditioning control unit 14 (step ST1).
Then, when the control unit 38 determines that the vehicle interior air conditioner 10 has started the heating operation, the control unit 38 causes the forced ventilation device 35 to start the reverse operation in the flow direction (step ST2).
The forced air blower 35 has an upper exhaust operation of discharging the air sucked from the lower opening 33 from the upper opening 32 and a lower exhaust operation of discharging the air sucked from the upper opening 32 from the lower opening 33. And are switched and executed continuously.

Further, the control unit 38 continuously switches to the forced blower device 35 so that the time of the upper exhaust operation is longer than the time of the lower exhaust operation immediately after the vehicle interior air conditioner 10 starts the heating operation. It is executed (step ST3).
As a result, in the forced air-conditioning device 35, a part of the heated and air-conditioned air blown out from the lower air outlet 20 of the front seat 5 by the passenger compartment air-conditioning device 10 is seated on the rear seat 5 of the occupant's knees. , Thighs, can be sprayed preferentially in front of the upper body.
Moreover, since the time of the upper exhaust operation is longer than the time of the lower exhaust operation, the air blown out by the upper exhaust operation can remain around the occupant's knees, thighs, and upper body, and stays around these. It will be easier.
In addition, instead of making a time difference between the upper exhaust operation and the lower exhaust operation, a difference in the amount of air blown may be made.

In this way, the vehicle interior air conditioner 10 continues to heat the vehicle interior 2 while the forced air blower 35 continuously switches between the upper exhaust operation and the lower exhaust operation.
Then, when the heating of the vehicle interior 2 approaches, for example, the target temperature and becomes stable, the vehicle interior air conditioner 10 weakens the air conditioning. For example, reduce the amount of air blown out.
When the control unit 38 detects that the heating of the vehicle interior 2 has progressed based on, for example, the weakening of the air conditioning (step ST4), the control unit 38 determines the time of the upper exhaust operation and the time of the lower exhaust operation by the forced air blower 35. The switching operation of the forced air blower 35 is changed so as to be aligned (step ST5).
The control unit 38 may determine that the heating of the vehicle interior 2 has progressed, for example, based on the air conditioning state information from the vehicle interior air conditioning control unit 14. Further, the control unit 38 may independently determine that the heating of the vehicle interior 2 has progressed based on, for example, the detected temperature of the temperature sensor 11.
This allows air to be forcibly circulated between the air around the knees and thighs of the occupant seated on the rear seat 5 and the air around the toes of the occupant under the seat 5.
As a result, the perimeter of the occupant's lower limbs can be generally uniformed to the desired comfortable heating temperature. It becomes difficult to be partially warmed.

FIG. 5 is a control flowchart showing an example of reverse operation in the flow direction during cooling.
The control unit 38 starts the process of FIG. 4, for example, when the vehicle interior air conditioner 10 starts the cooling operation.
The control unit 38 may determine the start of the cooling operation based on, for example, the air conditioning state information from the vehicle interior air conditioning control unit 14 (step ST11).
Then, when the control unit 38 determines that the vehicle interior air conditioner 10 has started the cooling operation, the control unit 38 causes the forced air blower 35 to start the reverse operation in the flow direction (step ST12).
The forced air blower 35 has an upper exhaust operation of discharging the air sucked from the lower opening 33 from the upper opening 32 and a lower exhaust operation of discharging the air sucked from the upper opening 32 from the lower opening 33. And are switched and executed continuously.

Further, the control unit 38 continuously switches the forced air blower 35 to the forced air blower 35 so that the time of the lower exhaust operation is longer than the time of the upper exhaust operation immediately after the vehicle interior air conditioner 10 starts the cooling operation. It is executed (step ST13).
As a result, in the forced air-conditioning device 35, a part of the air-conditioned air blown out from the air outlet 20 at a high position such as the upper part of the dashboard 6 by the passenger compartment air-conditioning device 10 is seated on the rear seat 5. It can be sprayed preferentially to the feet of the air conditioner.
Moreover, since the time of the lower exhaust operation is longer than the time of the upper exhaust operation, the air blown out by the lower exhaust operation can remain around the feet of the occupant and easily stays around them.
In addition, instead of making a time difference between the upper exhaust operation and the lower exhaust operation, a difference in the amount of air blown may be made.

In this way, the vehicle interior air conditioner 10 continues to heat the vehicle interior 2 while the forced air blower 35 continuously switches between the upper exhaust operation and the lower exhaust operation.
Then, when the heating of the vehicle interior 2 approaches, for example, the target temperature and becomes stable, the vehicle interior air conditioner 10 weakens the air conditioning. For example, reduce the amount of air blown out.
When the control unit 38 detects that the cooling of the vehicle interior 2 has progressed based on, for example, the air conditioning being weakened (step ST14), the time of the upper exhaust operation and the time of the lower exhaust operation by the forced blower 35 are set. The switching operation of the forced air blower 35 is changed so as to be aligned (step ST15).
The control unit 38 may determine that the cooling of the vehicle interior 2 has progressed, for example, based on the air conditioning state information from the vehicle interior air conditioning control unit 14. Further, the control unit 38 may independently determine that the cooling of the vehicle interior 2 has progressed based on, for example, the detected temperature of the temperature sensor 11.
As a result, air can be forcibly circulated between the air around the knees and thighs of the occupant seated on the rear seat 5 and the air around the toes of the occupant under the seat 5.
As a result, the perimeter of the occupant's lower limbs can be generally homogenized to the desired comfortable cooling temperature. Partially hard to get cold.

As described above, in the present embodiment, the aisle 34 is provided around the seat 5 on which the occupant in the passenger compartment 2 of the vehicle is seated, and the openings at both ends of the aisle 34 are located in the passenger compartment 2. do. Then, the forced blower device 35 that allows air to flow inside the communication passage 34 keeps repeatedly changing the flow direction of the air in the communication passage 34 during continuous operation. For example, the flow direction is repeatedly reversed.
Therefore, at the location around the sheet 5 to which the air flow from the communication passage 34 is supplied, the air flow whose flow direction keeps changing repeatedly is supplied. As a result, the temperature of the portion around the sheet 5 to which the air flow from the communication passage 34 is supplied can be appropriately adjusted. Crew comfort can be improved.
In particular, by continuously changing the flow velocity and the direction, a strong air flow is unlikely to occur suddenly, and discomfort due to the change in the air flow can be less likely to occur.
On the other hand, when an air flow in a constant direction is always supplied, a constant air flow continues to be generated at the portion corresponding to the opening, so that the air flow may be excessively heated or cooled over time. In this case, the airflow can improve the initial comfort, but in the long run local heating or cooling will occur and the comfort of the occupant will be impaired.
Further, since both ends of the communication passage 34 are located in the passenger compartment 2, only the air in the passenger compartment 2 is circulated. Therefore, the temperature around the occupant seated on the seat 5 can be leveled or made uniform to a suitable temperature without impairing the air-conditioning function of the entire interior of the vehicle interior 2 by the vehicle interior air-conditioning device 10.

In the present embodiment, the communication passage 34 is provided in the vehicle interior 2 along the vertical direction, and one opening is provided so as to be displaced higher than the other opening. The openings at both ends of the communication passage 34, which opens at both ends in the vehicle interior 2, are provided so as to be offset vertically. Therefore, in the air conditioning in the vehicle interior 2 by the vehicle interior air conditioner 10, even if the air conditioning is advanced, a temperature difference tends to remain in the vertical direction of the company due to the uneven arrangement of the outlets 20, but the temperature in the vertical direction is likely to remain. Differences can be suppressed to improve leveling or homogenization.

In the present embodiment, one opening is provided near the floor surface in the passenger compartment 2, and the other opening is provided at a position higher than the upper surfaces of the knees and thighs so as to be at least higher than the seat surface of the seat 5. Be done. Therefore, a part of the air flow blown out from the air outlet 20 near the floor surface of the vehicle interior air conditioner 10 can be supplied from above to the knees and thighs of the occupant seated on the seat surface of the seat 5.
Then, by continuously changing the flow direction of the air in the communication passage 34, the ambient temperature from the thigh to the toes of the occupant seated on the seat surface of the seat 5 can be leveled or made uniform.

In this embodiment, priority can be given to supplying the heated air for heating from the upper opening 32 to the vicinity of the occupant's knees and thighs. Even when the heating in the passenger compartment 2 is not advanced, the temperature around the occupants can be raised at an early stage and in a wide range. Moreover, when the heating in the vehicle interior 2 is advanced, even if the heating by the vehicle interior air conditioner 10 is weakened, it is possible to improve the leveling or equalization of the air temperature around the occupants.

In the present embodiment, the cooled air for cooling blown from the upper part of the passenger compartment 2 into the passenger compartment 2 is supplied from the lower opening 33 to the vicinity of the occupant's toes and shins. Can be prioritized. Even when the air conditioner in the passenger compartment 2 is not cooled, the temperature around the occupant can be lowered at an early stage and in a wide range. Moreover, when the cooling in the vehicle interior 2 is advanced, even if the cooling by the vehicle interior air conditioner 10 is weakened, it is possible to improve the leveling or equalization of the air temperature around the occupants.

In the above embodiment, the flow direction of the air in the communication passage 34 is changed so as to be switched between forward rotation and reverse rotation.
In addition to this, for example, the flow direction of the air in the communication passage 34 may be provided with a period for temporarily stopping the blowing.
Further, instead of reversing the flow direction, switching may be performed between stopping and blowing in one direction.

[Second Embodiment]
Next, a second embodiment of the present invention will be described. In the following description, the differences from the second embodiment will be mainly described.

FIG. 6 is an explanatory diagram of a main part configuration of an individual air conditioner for a vehicle according to a second embodiment.
In FIG. 6, the connecting passage 34 is provided on the dashboard 6 located on the front side of the front seat 5 in the vehicle interior 2.

The communication passage 34 is provided along the vertical direction on the dashboard 6. As a result, the upper opening 32 is provided at a position higher than the lower opening 33.

The lower opening 33 opens to the lower surface of the dashboard 6. As a result, the lower opening 33 opens near the floor surface of the vehicle interior 2. The air outlet 20 of the air conditioning duct 19 is located near the lower opening 33.
The upper opening 32 opens to the rear surface of the dashboard 6. As a result, the upper opening 32 is provided so as to face the front seat 5 at a position higher than the seating surface of the front seat 5. It is provided so as to face the seat 5 in the front row. It is located directly above the knee or thigh of the occupant seated on the seat 5.
As a result, the communication passage 34 communicates between the lower side and the rear side of the dashboard 6, and the air in the vehicle interior 2 flows between them.

Further, in FIG. 6, a partition plate 31 is provided on the upper side of the upper opening 32.
The partition plate 31 extends to the left and right with a width corresponding to, for example, the sheet 5, and extends along the front-rear direction. The partition plate 31 extends rearward from the upper opening 32 and extends above the thighs of the occupant seated in the seat 5.
As a result, the partition plate 31 can partition the vehicle interior 2 up and down.

Then, the control unit 38 controls the operation of the forced ventilation device 35 according to the temperature, humidity, amount of solar radiation, operating time, and the operating state of the vehicle interior air conditioner 10. Then, the operation of the forced blower device 35 is controlled so as to repeatedly reverse the flow direction of the air in the communication passage 34 during the continuous operation.

As described above, in the place around the sheet 5 to which the air flow from the communication passage 34 is supplied in the present embodiment, the air flow whose flow direction keeps changing repeatedly is supplied. As a result, the temperature of the portion around the sheet 5 to which the air flow from the communication passage 34 is supplied can be appropriately adjusted. Crew comfort can be improved.
In particular, by continuously changing the flow velocity and the direction, a strong air flow is unlikely to occur suddenly, and discomfort due to the change in the air flow can be less likely to occur.
On the other hand, when an air flow in a constant direction is always supplied, a constant air flow continues to be generated at the portion corresponding to the opening, so that the air flow may be excessively heated or cooled over time. In this case, the airflow can improve the initial comfort, but in the long run local heating or cooling will occur and the comfort of the occupant will be impaired.
Further, since both ends of the communication passage 34 are located in the passenger compartment 2, only the air in the passenger compartment 2 is circulated. Therefore, the temperature around the occupant seated on the seat 5 can be leveled or made uniform to a suitable temperature without impairing the air-conditioning function of the entire interior of the vehicle interior 2 by the vehicle interior air-conditioning device 10.

In the present embodiment, a partition plate 31 for vertically partitioning the vehicle interior 2 is provided on the upper side of the communication passage 34.
Therefore, the communication passage 34 switches air to flow under the partition plate 31.
Air is suitably circulated on the lower side of the partition plate 31, and the effect of leveling or equalizing the air temperature around the occupant can be enhanced on the lower side of the partition plate 31.

The above embodiments are examples of preferred embodiments of the present invention, but the present invention is not limited thereto, and various modifications or modifications can be made without departing from the gist of the present invention.

For example, in the above embodiment, the individual air conditioner 30 is used together with the vehicle interior air conditioner 10 in order to improve the comfort of the occupant seated on the seat 5.
In addition to this, for example, the individual air conditioner 30 may be used by itself to improve the comfort of the occupant seated on the seat 5.
