Description

  The present invention relates to a vehicle air-conditioning system capable of performing zone air-conditioning (personal air-conditioning) in which a part of a vehicle interior, for example, an occupant is used as an air-conditioning region.

  Conventionally, as a vehicle air-conditioning system, a system that performs zone air-conditioning that air-conditions only the occupant's surroundings rather than the entire vehicle interior has been proposed.

  As a first conventional example of such an air conditioning system for vehicles, there is one disclosed in Patent Document 1. As shown in FIG. 10, the vehicle air conditioning system 100 includes seat air conditioning auxiliary units 101 and 102 provided in a vehicle seat 110. The vehicle seat 110 includes a seat cushion 111 and a seat back 112. The seat cushion 111 includes a rigid panel member 111a, an elastic seat pad 111b supported by the panel member 111a, and a skin member 111c that covers the surface of the seat pad 111b. Similarly, the seat back 112 includes a panel member 112a having rigidity, a seat pad 112b having elasticity and supported by the panel member 112a, and a skin member 112c covering the surface of the seat pad 112b.

  One seat air conditioning auxiliary unit 101 is provided in the seat cushion 111, and the other seat air conditioning auxiliary unit 102 is provided in the seat back 112. Each of the seat air-conditioning auxiliary units 101 and 102 includes a plurality of fine holes (not shown) that penetrate the skin members 111c and 112c, two air holes 104 that penetrate the seat pads 111b and 112b, and seat pads 111b and 112b. A duct 105 provided on the back side and communicating between the two air blowing holes 104, a blower 106 provided in the duct 105, and a direction switching means 107 for switching the air blowing direction of the air flowing through the air blowing holes 104 are provided.

  According to the first conventional example, air conditioning air is supplied into the vehicle from an air conditioner (not shown) arranged in the instrument panel, and the air conditioning air is supplied to the vehicle seat 110 by the seat air conditioning auxiliary units 101 and 102. The temperature of the vehicle seat 110 is adjusted by sucking into the interior of the vehicle, or after the conditioned air is discharged from the interior of the vehicle seat 110 and sent to the upper portion of the vehicle seat 110, the conditioned air is returned to the air conditioner. As a result, a comfortable air environment can be formed around the occupant seated on the vehicle seat 110, and therefore, zone air conditioning can be performed with the occupant area of the driver's seat or passenger seat as the air conditioning region.

  As a second conventional example, there is one disclosed in Patent Document 2. As shown in FIG. 11, the vehicle air-conditioning system 120 includes a seat air-conditioning auxiliary unit 121 provided below the seat 130 of the driver seat or the passenger seat. The seat air-conditioning auxiliary unit 121 includes a suction port (not shown) that sucks air, a blower 122 that sucks air from the suction port, an evaporator 123 that cools air, a heater core 124 that heats air, and a blower outlet 125. Have The air outlet 125 opens on the upper surface of the seat air conditioning auxiliary unit 121.

  In this second conventional example, since the conditioned air 126 is blown out from the air outlet 125 toward the upper side of the seat 130, a comfortable air environment can be formed around the occupant seated on the seat 130, and the driver's seat or the passenger seat Zone air-conditioning can be performed in which the area around the passenger is air-conditioned.

  However, in the vehicle air conditioning system 100 according to the first conventional example, zone air conditioning is performed using the area around the driver or passenger seat as the air conditioning area. Therefore, there is a problem that a comfortable zone air-conditioning cannot be formed around the driver seat or the passenger seat. Since air flows from other areas into the zone air-conditioning area around the driver's seat or passenger's seat, the air-conditioning load cannot be reduced and energy saving cannot be achieved.

  In the vehicle air conditioning system 120 of the second conventional example, it is necessary to arrange the evaporator 123 and the heater core 124 dedicated to zone air conditioning, so that there is a problem that the system becomes complicated and expensive. Further, as in the first conventional example, air flows into the zone air-conditioning area around the driver's seat or passenger's seat from other areas, so the air-conditioning load cannot be reduced and energy saving cannot be achieved.

  Therefore, the present invention has been made to solve the above-described problems, and it is possible to simplify the system and reduce the cost, and to perform comfortable zone air-conditioning while saving energy by reducing the air-conditioning load. An object of the present invention is to provide a vehicle air-conditioning system.

  The present invention relates to an air conditioner that converts air sucked into a blower passage by a blower into a desired conditioned air by a heat exchanging unit and blows it into the passenger compartment, a suction port disposed around the seating of an occupant, and one end thereof A duct connected to the suction port; and the other end of the duct is connected, provided between the driver's seat and the passenger seat in the passenger compartment, and provided with an air outlet that blows air-conditioned air upward. Features.

  Preferably, the duct is provided with a blower that sends conditioned air sucked from the suction port to the outlet. It is preferable that the air outlet blows air-conditioned air obliquely upward near the driver's seat. The air outlet is preferably an elongated opening extending along the vehicle front-rear direction of the driver seat. The air outlet is provided on the front side of the vehicle from the back of the driver seat along the front-rear direction of the vehicle, and the air flow resistance of the air outlet gradually increases from the rear side to the front side of the vehicle. It is preferable to become. It is preferable that the air outlet is configured by an opening extending in the front-rear direction of the vehicle, and the width dimension of the opening is gradually narrowed from the rear side to the front side of the vehicle. It is preferable that the air outlet is composed of a plurality of air holes provided along the front-rear direction of the vehicle, and the opening area of the air holes gradually increases from the rear side to the front side of the vehicle. It is preferable that the air outlet includes a net-like body whose density gradually increases from the rear side toward the front side of the vehicle.

  The air outlet is preferably provided in an armrest or a center console. The armrest or the center console is provided with a lid member that can rotate in the width direction of the vehicle, and the lid member rotates between a closed position that covers the air outlet and an open position that opens the air outlet. It is preferable that the lid member guides the conditioned air blown from the outlet at the open position. The armrest or the center console is provided with a lid member that can rotate in the front-rear direction of the vehicle, and the lid member rotates between a closed position that covers the air outlet and an open position that opens the air outlet. It is preferable that the lid member shields a rear portion of the air outlet at the open position so that the conditioned air blown from the air outlet does not flow to the rear side of the vehicle. It is preferable that the armrest or the center console includes a lower air outlet that blows the conditioned air downward.

  According to the present invention, the conditioned air blown into the vehicle compartment from the air conditioner is sucked from the suction port located in the vicinity of the occupant's seating. Thus, the conditioned air is collected and the conditioned air flowing backward from the suction port is suppressed. The conditioned air sucked from the suction port is blown upward from the outlet through the duct to form an air curtain between the driver seat and the passenger seat. Next, the conditioned air is returned to the air conditioner. By such circulation of the conditioned air, a comfortable flow of the conditioned air is formed around the occupant and zone air conditioning is formed.

  In zone air conditioning mode, air conditioning air at the desired temperature is created using the heat exchanger of the air conditioner, so there is no need to install a heat exchanger exclusively for zone air conditioning, which can simplify the system and reduce costs. is there. In addition, the air curtain formed between the driver's seat and the passenger seat prevents air from flowing into the zone air-conditioning area around the passenger from other areas, improving the zone air-conditioning efficiency around the passenger and improving air conditioning. The load is reduced and energy saving can be achieved.

  As described above, it is possible to provide a vehicular air conditioning system that can simplify the system and reduce the cost, and can perform comfortable zone air-conditioning while saving energy by reducing the air-conditioning load.

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

(One embodiment)
1 to 9 show an embodiment of the present invention. 2 and 3, the vehicle 1 has an instrument panel 3 at the foremost portion in the passenger compartment 2. In the passenger compartment 2, a front driver's seat 4A and a front passenger seat 4B and one long rear seat 5 are provided. The driver seat 4A and the passenger seat 4B each have a seat cushion 4a, a seat back 4b, and a headrest 4c. The rear seat 5 includes a seat cushion 5a, a seat back 5b, and two headrests 5c.

  As shown in FIGS. 2 to 4, the vehicle air conditioning system 10 includes an air conditioner 11 and a seat air conditioning auxiliary unit 30. The air conditioner 11 includes an air conditioning unit 12 provided on the instrument panel 3.

  As shown in FIG. 4, an air passage 13 is formed in the air conditioning unit 12. In the uppermost stream of the air passage 13, an outside air introduction port 14 for introducing outside air, which is air outside the passenger compartment 2, and an inside air introduction port 15 for introducing inside air, which is air inside the passenger compartment, are provided. The outside air introduction port 14 and the inside air introduction port 15 are opened and closed by two intake doors 16a and 16b.

  A blower 17, an evaporator 18, and a heater core 19 are arranged in this order in the air passage 13. The evaporator 18 is a cooling source for blowing air, and the heater core 19 is a heating source for blowing air. A mix door 20 is provided between the evaporator 18 and the heater core 19.

  The blower 17 sucks the inside air and the outside air into the air passage 13 by the rotation of the fan. The evaporator 18 is arrange | positioned so that all the ventilation which passes along the ventilation path 13 may pass, and cools ventilation. The heater core 19 is arrange | positioned in the substantially half area | region of the ventilation path 13, and heats ventilation. The mix door 20 adjusts the ratio of the airflow that flows through the heater core 19 and the airflow that bypasses the heater core 19. Air conditioning air at a desired temperature is produced based on this air volume ratio.

  Downstream of the heater core 19, a defroster outlet 21, vent outlets 22a and 22b, and foot outlets 23a and 23b are provided. The defroster outlet 21 blows out conditioned air toward the windshield. The vent air outlet 22a on the driver's seat 4A side blows air conditioned air toward the upper body of the driver seated on the driver's seat 4A, and the vent air outlet 22b on the passenger seat 4B side seats the air conditioned air on the passenger seat 4B. Blow out toward the upper body of other occupants. The driver air outlet 23a on the driver's seat 4A side blows air conditioned air toward the lower body of the driver seated on the driver's seat 4A, and the foot air outlet 23b on the passenger seat 4B side sits on the passenger seat 4B with air conditioned air. Blows towards the lower body of the occupant. The defroster outlet 21 is opened and closed by a differential door 24. The vent outlets 22a and 22b are opened and closed by a vent door 25. The foot outlets 23a and 23b are opened and closed by a foot door 26.

  The control unit (not shown) controls the air conditioner 11 by a command from an operation panel (not shown). The control unit controls the blowing temperature and the like by a temperature sensor (not shown) of the air conditioner 11 disposed near the instrument panel 3.

  The seat air-conditioning auxiliary unit 30 is formed at a suction port 31 disposed around the driver's seat, a duct 32 having one end connected to the suction port 31, and the other end side of the duct 32. The blower outlet 33 interposed between the passenger seats 4B and the blower 34 that is provided in the middle of the duct 32 and sends the conditioned air sucked from the suction port 31 to the blower outlet 33 are provided.

  A pair of suction ports 31 are provided at the upper position of the seat back 4b of the driver's seat 4A and at the left and right positions with the headrest 4c interposed therebetween. There are a total of two suction ports 31, which are opened immediately after the upper body of the driver. One end of the duct 32 is connected to each suction port 31. Each suction port 31 is configured to be opened and closed by a lid (not shown). Each suction port 31 is opened during zone air conditioning, and closed with a lid (not shown) during overall air conditioning.

  As shown in FIG. 1, the air outlet 33 is provided between the driver's seat 4A and the passenger seat 4B. The air outlet 33 is set so as to blow the conditioned air at an inclination angle a toward the driver seat 4A from the vertical direction V, that is, obliquely upward near the driver seat 4A. The conditioned air blown obliquely upward from the air outlet 33 strikes the ceiling 2a of the passenger compartment 2 and flows to the outside in the width direction of the vehicle 1 along the ceiling 2a. Next, the conditioned air descends along the side part 2 b such as the side window of the passenger compartment 2.

  As shown in FIGS. 2 and 3, conditioned air is fed into the air outlet 33 from the back side of the driver's seat 4 </ b> A (the rear side of the vehicle 1) via the duct 32. The air outlet 33 is an elongated opening extending along the vehicle front-rear direction of the driver's seat 4A. As shown in FIG. 5, the width dimension W of the air outlet 33 gradually decreases from the rear side (right side in FIG. 5) to the front side (left side in FIG. 5). Since the air flow resistance on the front side of the vehicle 1 at the air outlet 33 is larger than the air flow resistance on the rear side, the conditioned air can be evenly blown from the air outlet 33 at each position in the front-rear direction of the vehicle 1.

  In the above configuration, when the air conditioner 11 is driven, air is sucked into the air passage 13 from the outside air inlet 14 and the inside air inlet 15 by the blower 17. The sucked air is converted into conditioned air at a desired temperature by the evaporator 18 and the heater core 19, and the conditioned air is sent from at least one air outlet 21, 22 a, 22 b, 23 a, 23 b, for example, the vent air outlet 22 a, 22 b to the vehicle compartment 2. It is blown out inside.

  During the entire air conditioning, the suction port 31 is closed. The conditioned air blown out from the air conditioner 11 into the passenger compartment 2 flows to almost the entire interior of the passenger compartment 2, and the entire interior of the passenger compartment 2 is air-conditioned.

  During the zone air conditioning, the suction port 31 is opened. The suction port 31 of the driver's seat 4 </ b> A sucks conditioned air with the suction force of the blower 34. The sucked air-conditioning air is blown out obliquely upward near the driver's seat 4A from the air outlet 33 through the duct 32 and air-conditions around the driver. The conditioned air that has undergone air conditioning is returned to the air conditioning unit 12. As a result, the conditioned air is intensively passed around the driver in the front seat and collected from the suction port 31, and the flow to the passenger compartment space behind the suction port 31 is suppressed.

  During the zone air conditioning described above, the air curtain 35 formed between the driver seat 4A and the passenger seat 4B suppresses air from flowing from the region on the passenger seat 4B side to the zone air conditioning region on the driver seat 4A side. For example, the warm air on the passenger seat 4B side is prevented from flowing into the zone air conditioning area on the driver seat 4A side during cooling. Further, since the air curtain 35 surrounds the left and right sides and the upper part of the driver's seat 4A, zone air conditioning around the driver's seat 4A can be performed effectively. For example, when conditioned air flows along the ceiling 2a located at the upper part of the passenger compartment 2, the air staying in the ceiling 2a is excluded and the ceiling 2a is cooled during cooling to suppress the radiant heat from the ceiling 2a. it can. Similarly, when the conditioned air flows along the side part 2b of the passenger compartment 2 during cooling, the side part 2b of the passenger compartment 2 can be cooled to suppress radiant heat from the side part 2b.

  The air outlet 33 extends in the front-rear direction of the vehicle 1 and blows the conditioned air evenly at each position in the front-rear direction of the vehicle 1, so that the air curtain is wide in the front-rear direction of the vehicle 1 and has an equal air volume in the width direction 35 can be formed, and the air curtain 35 can perform zone air conditioning over a wide range in the front-rear direction of the vehicle 1.

  Therefore, in the zone air conditioning mode, the conditioned air blown from the air conditioner 11 to the passenger compartment 2 is collected by the seat air conditioning auxiliary unit 30 and blown out from the outlet 33 to form the air curtain 35, and the zone around the driver seat 4A By reusing the air-conditioning air for the air-conditioning, the zone air-conditioning efficiency around the driver's seat 4A can be improved, the air-conditioning load can be reduced, and the energy can be saved.

  In the zone air conditioning mode, the air conditioning unit 12 uses the evaporator 18 and the heater core 19 to produce conditioned air at a desired temperature. Cost reduction is possible.

  As described above, the vehicle air-conditioning system 10 can simplify the configuration and reduce the cost, and can perform comfortable zone air-conditioning while saving energy by reducing the air-conditioning load.

  In the vehicle 1 in which the air conditioner 11 is mounted in advance, the present invention can be applied only by installing the suction port 31, the duct 32, the air outlet 33, and the like of the seat air conditioning auxiliary unit 30. Therefore, the present invention can be easily retrofitted.

  The suction port 31 is provided in the driver's seat 4A. Since the driver's seat 4A is an existing part on which an occupant is seated, the driver's seat 4A is the most suitable part for arranging the suction port 31, and is easy to install.

  The suction port 31 is provided in the upper part of the seat back 4b. The airflow of the air-conditioned air that has been air-conditioned is blown out from the vent outlet 22a to the upper body part of the occupant and around the head. Further, in the case of warm air, the air is blown out from the foot outlet 23a, and air current is generated in the upper part of the passenger compartment. For these reasons, the conditioned air can be efficiently sucked by the suction port 31 provided at the upper part of the seat back 4b.

  At the time of zone air conditioning, air conditioning air is sucked from the air inlet 31 of the driver's seat 4A by the suction force of the blower 34, and air curtain 35 is blown out from the air outlet 33 to form an air curtain 35. The air curtain 35 allows air to flow into the zone air-conditioning area on the driver's seat 4A side from the area on the passenger seat 4B side even when the amount of air-conditioning air blown from the air outlet 22a is small or the ventilation resistance of the duct 32 is large. Can be reliably suppressed, and air can be prevented from staying in the zone air-conditioning region on the driver's seat 4A side.

  The air outlet 33 blows air conditioned air obliquely upward near the driver's seat 4A. Accordingly, the conditioned air hitting the ceiling portion 2a of the passenger compartment 2 flows toward the driver's seat 4A side along the ceiling portion 2a in the width direction of the vehicle 1 and along the side portions 2b of the passenger compartment 2 such as side windows. Therefore, an air curtain that wraps around the driver's seat 4A can be reliably formed.

  The air outlet 33 is an elongated opening extending along the vehicle front-rear direction of the driver seat 4A. Accordingly, the air curtain 35 can be formed in a wide area of the driver, and the comfortable zone air conditioning is improved.

(Modification)
In the above embodiment, the air-conditioning air sucked from the suction port 31 is provided in the seat air-conditioning auxiliary unit 30 to send the conditioned air to the blow-out port 33. However, if necessary, a blower that sucks air into the duct may not be provided. . With such a structure, it is possible to further simplify the system and reduce the cost.

  In the above-described embodiment, the conditioned air is blown out from all the vent outlets 22a and 22b when the vent is blown out. You may comprise so that it can be made to blow out. Thereby, the vent blowing state according to a driver | operator's or other passenger | crew's liking can be selected. When the conditioned air is blown out only from the vent outlet 22a on the driver's seat side in the zone air conditioning mode, more comfortable zone air conditioning can be performed while saving energy by reducing the air conditioning load.

  In the above embodiment, as shown in FIG. 5, the width dimension W of the air outlet 33 is set to gradually increase from the rear side to the front side of the vehicle 1, but as a first modification, FIG. As shown in (b), the air outlet 33A is composed of a plurality of rectangular air outlets 40 provided along the front-rear direction of the vehicle 1, and the opening area of the air outlet 40 is set to the rear side of the vehicle 1 ( It can also be set to gradually decrease from the right side of FIGS. 6A and 6B toward the front side (left side of FIGS. 6A and 6B). Furthermore, as a second modification, as shown in FIG. 6C, the outlet 33B is directed from the rear side of the vehicle 1 (right side of FIG. 6C) to the front side (left side of FIG. 6C). Accordingly, it is possible to provide a net 41 that gradually becomes denser and denser. Also in these modified examples, the air flow resistance on the front side of the vehicle 1 at each of the air outlets 33A and 33B is larger than the air flow resistance on the rear side, so that the air outlets 33A and 33B are equally distributed at each position in the longitudinal direction of the vehicle 1. Air conditioned air can be blown out. Therefore, the air curtain can form an air curtain that is wide in the front-rear direction of the vehicle 1 and has a uniform air volume in the width direction.

  In the above embodiment, the air outlet 33 of the seat air conditioning auxiliary unit 30 is provided on the other end side of the duct 32 interposed between the driver's seat 4A and the passenger seat 4B, but FIG. 7 and FIG. ), The air outlet 33 of the seat air conditioning auxiliary unit 30 may be provided in the armrest 50 or the center console interposed between the driver's seat 4A and the passenger seat 4B. The conditioned air sent through the duct 32 is sent to the air outlet 33 through the armrest 50 or the inside of the center console. With such a configuration, the inside of the armrest 50 or the center console can be used as a part of the duct, so there is no need to newly provide a duct between the driver seat 4A and the passenger seat 4B.

  Furthermore, as shown in FIG. 7, the armrest 50 may be provided with a lid member 51 that can rotate in the width direction of the vehicle 1. The lid member 51 rotates between a closed position that covers the air outlet 33 and an open position that opens the air outlet 33. When the seat air-conditioning auxiliary unit 30 is operated, the lid member 51 is rotated to the open position to open the air outlet 33, and is also erected at the side end of the armrest 50 near the passenger seat 4B. As a result, the conditioned air blown from the outlet 33 can be guided by the lid member 51 so as to flow obliquely upward near the driver's seat 4A, and airflow from the area of the passenger seat 4B can be suppressed. On the other hand, when the seat air-conditioning auxiliary unit 30 is stopped, the lid member 51 is rotated to the closed position, and the air outlet 33 is covered with the lid member 51, whereby foreign substances such as dust can be prevented from entering from the air outlet 33.

  As another modified example, as shown in FIG. 8A, a lid member 52 that can rotate in the front-rear direction of the vehicle 1 may be provided on the armrest 50. The lid member 52 rotates between a closed position that covers the air outlet 33 and an open position that opens the air outlet 33. When the seat air-conditioning auxiliary unit 30 is operated, the lid member 52 is rotated to the open position to open the air outlet 33 and to stand at the rear part of the armrest 50. Accordingly, the rear portion of the armrest 50 can be shielded by the lid member 52 so that the conditioned air blown from the air outlet 33 does not diffuse to the rear side of the vehicle 1, and airflow from the rear seat area can be suppressed. . On the other hand, when the seat air-conditioning auxiliary unit 30 is stopped, the lid member 52 is rotated to the closed position and the air outlet 33 is covered with the lid member 52, so that foreign matters such as dust can be prevented from entering from the air outlet 33.

  Further, as shown in FIG. 8B, the armrest 50 is provided with an air outlet 33 at an upper portion of the armrest 50 and a lid member 52 provided so as to be rotatable in the front-rear direction of the vehicle 1 and covering the air outlet 33. A lower outlet 53 can also be provided at the bottom of the. As a result, when the seat air conditioning auxiliary unit 30 is operated, the lid member 52 can be rotated to blow the conditioned air upward from the air outlet 33 and to blow the conditioned air downward from the lower air outlet 53.

  In the said embodiment, although the vent blower outlet 22a of the air conditioning apparatus 11 blows off conditioned wind toward a driver | operator's upper body part, according to the wind speed of an air conditioned wind, it is the up-down direction from the vent blower outlet 22a. The blowing angle can be changed. For example, as shown to Fig.9 (a), when the air-conditioning wind blown out is fast, the blowing angle of the up-down direction from the vent blower outlet 22a is set toward a driver | operator's upper body part. On the other hand, as shown in FIG. 9B, when the conditioned air to be blown out is slow, the conditioned air is considerably lowered in the middle, so that the vertical blowing angle from the vent outlet 22a is set to be relatively large. Thereby, even if the conditioned air blown out from the vent outlet 22a is slow, the amount of conditioned air reaching the upper body of the driver can be increased.
