[First Embodiment]
FIG. 1 is an explanatory view schematically showing the structure of an automobile 1 to which an air conditioner 2 according to a first embodiment of the present invention is applied.

The automobile 1 is a kind of vehicle. An occupant room in which an occupant gets in is formed in the front-rear center of the vehicle body of the automobile 1. A front chamber for arranging a fuel engine or the like is formed in the front portion of the vehicle body. A rear chamber that can be used as a cargo compartment or the like is formed in the rear portion of the vehicle body.
The passenger compartment includes a substantially square floor panel 11, a pair of A pillars 12 erected at the front corner of the floor panel 11, a pair of B pillars 13 erected at the center in the front-rear direction of the floor panel 11, and the floor panel 11. It has a pair of C pillars 14 erected on the rear corner. The upper end of the A pillar 12 and the upper end of the C pillar 14 are connected by a roof rail 15. The upper end of the B pillar 13 is joined to the center of the roof rail 15 in the front-rear direction. A substantially rectangular roof panel 16 is joined between the pair of left and right roof rails 15.
A toe board 17 is disposed between the front edge of the floor panel 11 and the lower portions of the pair of A pillars 12, and a dashboard 18 is disposed above the toe board 17. A windshield 19 is fitted so as to be surrounded by the dashboard 18, the upper portions of the pair of A pillars 12, and the front edge of the roof panel 16. A rear glass 20 is fitted between the upper portions of the pair of C pillars 14.
Between the A pillar 12 and the B pillar 13 arranged in the front-rear direction, a front door (not shown) that is rotatably supported by the A pillar 12 is disposed. A rear door (not shown) that is rotatably supported by the B pillar 13 is disposed between the B pillar 13 and the C pillar 14. A pair of side sills 21 are joined to both edges in the left-right width direction of the floor panel 11.
Thus, the passenger compartment of the automobile 1 is a substantially cubic box-shaped space.
A center tunnel 22 extending in the front-rear direction so as to protrude into the passenger compartment is formed at the center in the left-right width direction of the floor panel 11. Below the center tunnel 22, for example, a drive shaft (not shown) for transmitting the driving force of the fuel engine to the rear wheels is arranged.
A driver seat 23 on which a driver sits and a navigation seat 24 on which a navigator sits are attached to the front portion of the floor panel 11 side by side in the left-right width direction as front seats. The driver seat 23 has a seat portion 41 and a back portion 42. The navigation sheet 24 includes a seat portion 41 and a back portion 42. The center tunnel 22 is located between the seat 41 of the driver seat 23 and the seat 41 of the navigation seat 24. On the center tunnel 22, a shift lever 25, a side brake lever (not shown), a console box 26 as an interior member, and the like are attached.
In front of the driver seat 23 and the navigation seat 24, the dashboard 18 extending in the left-right width direction is located. A steering wheel 27 is provided in front of the driver seat 23 so as to protrude rearward from the dashboard 18.
A bench seat 28 on which a plurality of passengers can sit is attached as a rear seat to the rear portion of the floor panel 11. The bench seat 28 has a seat portion 41 and a back portion 42. The bench seat 28 has a lateral width equivalent to that of the floor panel 11. Up to three passengers can normally sit on the bench seat 28.

By the way, in the conventional vehicle 1, it is common to use a fuel engine as a power source of the vehicle 1. However, due to restrictions on carbon dioxide emissions, the automobile 1 in recent years may adopt a hybrid drive system that uses both a fuel engine and an electric motor. Moreover, only an electric motor may be employed as a power source.
Since the automobile 1 using an electric motor does not have a fuel engine as a heat source and a power source or does not always operate, it is mounted on the automobile 1 to generate cool air or warm air used for air conditioning of the passenger compartment. The power of the battery that is being used will be used. In this case, since the electric power of the battery mounted on the automobile 1 is consumed for air conditioning, it is necessary to shorten the travelable distance or to suppress the travel performance such as the speed.
Thus, in the air conditioner 2 of the automobile 1, it is required in the future to improve energy consumption by the air conditioner 2. In particular, the occupant tends to feel cold on the toes of the lower limbs in winter.

  Therefore, in the present embodiment, a personal air conditioner 2 that performs air conditioning for each passenger, for example, is proposed instead of air-conditioning the entire passenger compartment of the automobile 1. By using such an air conditioner 2, for example, it is possible to reduce the necessity of heating or cooling the entire passenger compartment of the automobile 1. Moreover, since the burden can be reduced even when it uses together with the air conditioner which air-conditions the whole passenger compartment, it can anticipate reducing the energy consumption of the air conditioner 2 in the motor vehicle 1 as a result.

FIG. 2 is an explanatory diagram of the configuration of the air conditioner 2 according to the first embodiment of the present invention.
The air conditioner 2 includes an inner duct 51, an inner fan 52, an outer duct 54, an outer fan 55, a front duct 57, a front fan 58, a temperature control unit 61, and a control unit 71.

  The temperature control unit 61 may be, for example, a unit box 62 in which a heater 63, a Peltier element 64, and a temperature sensor 65 are arranged. The heater 63 heats the air in the unit box 62 using the power of the battery mounted on the automobile 1. The Peltier element 64 cools the air in the unit box 62 using the power of the battery mounted on the automobile 1. In addition to this, for example, the temperature control unit 61 may be connected to a duct of an air conditioner that air-conditions the entire passenger compartment, and may receive supply of heated or cooled air from the entire air conditioner. Further, a heating medium such as cooling water for the fuel engine or a refrigerant may be supplied. The temperature sensor 65 detects the temperature of air in the unit box 62.

  The inner duct 51 has an inner vent 53 at one end, and the other end is connected to the unit box 62 of the temperature control unit 61. The inner vent 53 may be provided with a wind direction adjusting mechanism such as a louver. An inner fan 52 for sucking or blowing air at a low speed may be provided in a duct inside the inner vent 53.

  The outer duct 54 has an outer vent 56 at one end and is connected to the unit box 62 of the temperature control unit 61 at the other end. The outer vent 56 may be provided with a wind direction adjusting mechanism such as a louver. An outer fan 55 for blowing or blowing air at a low speed may be provided in a duct inside the outer vent 56.

  The front duct 57 has a front intake port 59 at one end, and the other end is connected to the unit box 62 of the temperature control unit 61. The front intake port 59 may be provided with a wind direction adjusting mechanism such as a louver. A front fan 58 for sucking air at a low speed may be provided in a duct inside the front intake port 59.

  The control unit 71 controls the operation of the air conditioner 2. The control unit 71 may be a microcomputer, for example. The control unit 71 may be integrated with another control unit 71 provided in the automobile 1 and one microcomputer. An example of such a microcomputer is an ECU. For example, a heater 63, a Peltier element 64, a temperature sensor 65, an inner fan 52, an outer fan 55, and a front fan 58 are connected to the control unit 71.

Such an air conditioner 2 is provided for each occupant seated on the seat, for example. Here, it is installed with respect to the navigation sheet 24.
Specifically, the inner vent 53 is provided on the side surface on the navigation sheet 24 side of the console box 26 disposed inside the seat portion 41 of the navigation sheet 24. The inner vent 53 is provided at a height position spaced above the seat surface of the seat 41 of the navigation sheet 24.
The outer vent 56 is provided at a height position spaced above the seating surface of the seat 41 on the outer side of the seat 41 of the navigation sheet 24.
The front intake port 59 is formed in a toe board provided under the front foot of the navigation seat 24. The front intake port 59 is provided at a position lower than the seat surface of the navigation seat 24.
The temperature adjustment unit 61 is provided in the console box 26. Therefore, the inner duct 51 is also provided in the console box 26. The outer duct 54 projects from the console box 26 and extends to the outside of the seat 41 of the navigation sheet 24 through the lower side of the seat 41 of the navigation seat 24. Further, the front duct 57 projects from the console box 26 and extends forward along the center tunnel 22 until reaching the front side of the toe board, for example.

Next, the operation of the air conditioner 2 will be described.
FIG. 3 is an explanatory diagram showing the air flow around the occupant by the air conditioner 2 of FIG.

The control unit 71 of the air conditioner 2 acquires, for example, the temperature detected by the temperature sensor 65, and controls the operation and stop of the heater 63 and the Peltier element 64 so as to obtain a desired temperature. The control target temperature may be any temperature that increases the sensible temperature of the occupant. When heating is required in winter, for example, the temperature may be about 20 degrees.
Further, the control unit 71 starts the air conditioning control by operating the inner fan 52, the outer fan 55, and the front fan 58 based on a user operation. At this time, the control unit 71 rotates the inner fan 52, the outer fan 55, and the front fan 58 at a low speed. For example, the air flow by the inner fan 52 or the outer fan 55 is rotated at a low speed so as to be 0.01 m / sec or more and 6 m / sec or less. Thus, by setting the flow velocity to 6 m / sec or less, the decrease in the temperature of the sensation due to the air flow can be reduced to about 1 degree or less. The front fan 58 may have a speed corresponding to the sum of the flow speed of the inner fan 52 and the flow speed of the outer fan 55. Accordingly, a weak air flow from the inner fan 52 toward the front fan 58 and a weak air flow from the outer fan 55 toward the front fan 58 can be generated. Preferably, the air flow of the inner fan 52 and the outer fan 55 may be further reduced so that the air flow by the front fan 58 is 0.01 m / second or more and 6 m / second or less. Further, the flow rate of the inner fan 52 and the flow rate of the inner fan 52 are preferably basically the same, but may be different.
Thereby, the temperature-controlled air flow is blown out from the inner vent 53 and the outer vent 56. The blown air flow falls on the seat 41 and merges on the seat surface. The air flow that falls on the seating surface and merges stays on the seating surface.

The front intake port 59 sucks in air on the front side of the seat portion 41 of the navigation seat 24. Thereby, the air staying on the seating surface moves forward on the seating surface and moves from the seating surface to the front of the seat. It moves toward the front intake port 59.
In this manner, the air conditioner 2 generates weak air flow from both the left and right sides of the seating surface of the seat to generate air staying on the seating surface, and further moves the airflow slowly toward the front of the seating surface. be able to. An air flow that slowly flows from the thigh to the toes along the lower limb of the occupant seated on the seat can be generated, and this air flow can form a temperature-controlled air layer that wraps the entire limb of the occupant .

As described above, in the present embodiment, the inner vent 53 and the outer vent 56 are provided on both sides in the width direction of the sheet, and a weak air flow is ejected from both of the vents. Therefore, the low-speed weak air flow blown out from the inner vent 53 and the low-speed weak air flow blown out from the outer vent 56 are likely to merge on the seat surface and stay on the seat. The air flow is supplied onto the thigh of the occupant seated on the seat and tends to stay on the thigh. Moreover, the air flow is sucked weakly from the front intake port 59 provided on the front side of the seat portion 41 of the seat. Therefore, the air flow staying on the seat moves from the top to the front of the seat portion 41 of the seat.
As a result, the airflow flows along the lower leg of the occupant seated on the seat. It flows from the thigh of the occupant toward the toes. As a result, the lower limbs such as the thigh, knees, shin, ankles, and toes of the occupant can be wrapped in the temperature-controlled air flow, and the temperature of the entire lower limbs can be adjusted evenly and globally. It becomes possible to suppress the cooling of the lower limbs such as the occupant's thigh as a whole.

In addition, since the generated airflow is weak, it is difficult to remove heat from the occupant as in an early airflow. If heat is taken away by the air flow, the temperature of the air flow must be adjusted to compensate for it.
In addition, since the airflow flows from the left and right sides of the seat and then flows forward, the airflow rises along the upper body as if the airflowed from the front side of the occupant toward the occupant, for example. Or never reach the periphery. No discomfort caused by wind blowing on the face.

  In the present embodiment, the inner vent 53 is particularly provided on the side surface of the console box 26 provided on the inner side in the width direction of the seat portion 41 of the seat. Thereby, the inner vent 53 can be easily provided at a height position above the thigh using the height of the console box 26.

  In the present embodiment, a temperature control unit 61 that warms the air is provided in the console box 26. Therefore, the inner duct 51 from the temperature control unit 61 to the inner vent 53 and the outer duct 54 from the temperature control unit 61 to the outer vent 56 become the shortest, and heat loss in these ducts can be minimized. . Further, it is not necessary to provide the temperature adjustment unit 61 exposed around the sheet.

In the present embodiment, the air flow discharged from the inner vent 53 and the outer vent 56 is sucked from the front intake 59 and returned to the temperature control unit 61 through the front duct 57. As a result, the air flow circulates and the amount of heat required to warm the air flow again can be reduced. During the operation period in which the temperature control unit 61 is continuously operated, the total amount of heat required to keep the airflow warm can be significantly reduced.
Thereby, the energy used for air conditioning can be reduced without impairing comfort such as a passenger's sensible temperature.

[Second Embodiment]
The air conditioner 2 according to the second embodiment is different from that of the first embodiment in that the inner vent 53 and the outer vent 56 are arranged in the seat. In the following description, differences from the first embodiment will be mainly described. Moreover, the same code | symbol as 1st Embodiment is used for convenience of explanation.

  FIG. 4 is an explanatory diagram of the configuration of the air conditioner 2 according to the second embodiment of the present invention. The overall air flow around the passenger is substantially the same as in FIG.

  The inner vent 53 is provided on the inner side in the width direction of the back portion 42 of the seat. The outer vent 56 is provided on the outer side in the width direction of the back portion 42 of the seat. Preferably, the back portion 42 of the seat has a portion projecting forward so as to support the left and right sides of the waist, and the inner vent 53 and the outer vent 56 may be provided in these projecting portions. The inner duct 51 and the outer duct 54 protrude outward from the console box 26 and extend to the back portion 42 of the navigation seat 24.

  In the present embodiment, an inner vent 53 and an outer vent 56 are provided on the inner side in the width direction of the back portion 42 of the seat. Even in this case, by blowing out a weak air flow from both of these vents and sucking in a weak air flow from the front intake port 59, the thigh, knee, shin, ankle, By wrapping the entire lower limb such as the toes with a conditioned air flow, the temperature of the entire lower limb can be adjusted evenly and globally. It becomes possible to suppress the cooling of the lower limbs such as the occupant's thigh as a whole.

  In the present embodiment, the inner vent 53 and the outer vent 56 are arranged on the sheet. In addition to this, for example, one of the inner vent 53 and the outer vent 56 is arranged as shown in FIG. It may be provided next to the sheet. For example, the inner vent 53 may be provided in the console box 26 or the like as in the first embodiment.

[Third Embodiment]
The air conditioner 2 according to the second embodiment differs in the operation of the outer fan 55 compared to that of the first embodiment.

Moreover, the same code | symbol as 1st Embodiment is used for convenience of explanation.

FIG. 5 is an explanatory diagram of the configuration of the air conditioner 2 according to the third embodiment of the present invention.
FIG. 6 is an explanatory diagram showing the air flow around the passenger by the air conditioner 2 of FIG.

  The control unit 71 operates the inner fan 52 at a low speed and blows a weak air flow from the inner vent 53. Further, the control unit 71 operates the outer fan 55 and the front fan 58 at a low speed, and sucks a weak air flow from the outer ventilation port 56 and the front intake port 59. In this case, the inner fan 52 is rotated at a low speed so that the airflow is 0.01 m / second or more and 6 m / second or less. The front fan 58 and the outer fan 55 may have a speed at which the total air flow corresponds to the flow rate of the inner fan 52. Thus, a weak air flow from the inner fan 52 toward the outer fan 55 and a weak air flow from the inner fan 52 toward the outer fan 55 can be generated. In order to enhance the effect of the front intake port 59 that is far away, the flow rate of the front fan 58 may be made higher than the flow rate of the outer fan 55.

  In the present embodiment, a weak air flow is sucked from the outer vent 56. Thereby, a weak air flow from the inner vent 53 toward the outer vent 56 is generated. A weak air flow can be generated that flows along the front of the upper body and along the upper surface of the thigh in front of the occupant seated in the seat. Moreover, the air flow is sucked weakly from the front intake port 59 provided on the front side of the seat portion 41 of the seat. Therefore, the airflow flowing so as to stay on the seat moves from the top of the seat portion 41 to the front. As a result, the lower limbs such as the thigh, knees, shin, ankles, and toes of the occupant can be wrapped in the temperature-controlled air flow, and the temperature of the entire lower limbs can be adjusted evenly and globally. It becomes possible to suppress the cooling of the lower limbs such as the occupant's thigh as a whole.

[Fourth Embodiment]
The air conditioner 2 according to the fourth embodiment is different from that of the first embodiment in that the front intake port 59 is disposed at the lower part of the dashboard 18. In the following description, differences from the first embodiment will be mainly described. Moreover, the same code | symbol as 1st Embodiment is used for convenience of explanation.

  In the present embodiment, the front intake port 59 is provided at the lower part of the dashboard 18 located above the toe board 17. Therefore, as in the case where the front intake port 59 is provided in the toe board 17, it is possible to form an air layer that entirely wraps the lower limbs of the occupant seated on the seat by the air flow. And since it exists in the lower position which is hard to see from a passenger | crew in the position above the toe board 17, it can avoid affecting the design property in a passenger | crew interior. Moreover, the front intake port 59 can be easily formed without affecting the rigidity of the vehicle body and the like because it is provided not on the member constituting the vehicle body such as the toe board 17 but on the interior part such as the dashboard 18.

  In addition to this, the front intake port 59 may be provided in the side sill 21 or the floor panel 11. However, when the front intake port 59 is formed in these members, raindrops, dust, and the like easily enter the front duct 57, so that countermeasures are indispensable. In particular, when these members are formed not at the front end portion but at the center portion or the rear side portion, the front intake port 59 can be easily touched by human eyes. There is a possibility of affecting the design in the passenger compartment.

  The above embodiment is an example of a preferred embodiment of the present invention. The present invention is not limited to this, and various modifications or changes can be made without departing from the scope of the invention.
