Description

  The present invention relates to a vehicle air conditioner, and more particularly to a vehicle air conditioner that adjusts the flow of conditioned air to reduce the difference in temperature between the window side and the center side of a vehicle, such as near a window where heat release or heat inflow increases. .

  The following systems are known as conventional vehicle air conditioning systems. FIG. 9A shows the flow of conditioned air in the vent blowing mode during cooling. An upper suction port 104 is provided so as to sandwich the headrest 103 of the driver's seat 101 of the vehicle 100, and the upper suction port 104 sucks conditioned air blown from an upper air outlet 105 in front of the vehicle. With this system, an air-conditioning wind that passes around the upper body of the driver 106 sitting on the driver's seat 101 is formed.

  On the other hand, FIG. 9B shows the flow of conditioned air in the foot blowing mode during heating. A lower suction port 107 is provided below the driver's seat 101 of the vehicle 100, and the lower suction port 107 sucks in air-conditioned air blown from a foot outlet 108 in front of the vehicle.

  As shown in FIGS. 9A and 9B, in the conventional vehicle air conditioning system, air-conditioning air that passes around the upper half of the driver 106 is formed during cooling, and air conditioning that passes around the lower half of the driver during heating. Wind is formed. In either mode, the conditioned air blown from the front of the driver's seat 101 is sucked from the upper suction port 104 or the lower suction port 107. Therefore, when cooling or warming the entire body of the driver 106, such as during cooling in summer or heating in the winter, for example, air conditioning that wraps from the thigh to the trunk or neck of the driver 106 It is difficult to generate wind.

  In particular, it is difficult to flow conditioned air around the neck, shoulders, and upper arms around the driver's 106 located near the window of the vehicle 100, and the driver 106 uses air conditioned air in a region where the temperature difference in the passenger compartment is severe. There is a problem that it is difficult to cool or warm.

  Specifically, in winter, the vehicle interior is usually heated and traveled. However, the heat in the vehicle interior is easily released outside the vehicle compartment through the window, and the center side of the vehicle 100 is warm. Becomes cold and a temperature difference occurs in the passenger compartment. In particular, when the vehicle 100 is traveling, heat in the vehicle interior is easily released outside the vehicle through the window due to the flow of air generated around the vehicle 100. As a result, the vicinity of the neck, shoulder and upper arm of the driver 106 located near the window is in a state of being easily cold.

  On the other hand, in the summer, the vehicle interior is usually cooled, but heat outside the vehicle interior easily flows into the vehicle interior through the window, the center side of the vehicle interior is cooled, but the vehicle 100 is hot near the window. As a result, a temperature difference occurs in the passenger compartment. In particular, near the window of the vehicle 100, direct sunlight may enter, and the neck, shoulder, and upper arm area of the driver 106 located near the window are likely to get hot.

  In other words, at the window of the vehicle 100, heat release from the passenger compartment and heat inflow from the outside of the passenger compartment are likely to occur, and measures for cooling and warming around the neck, shoulders, and upper arms of the driver 106 located near the window are required. ing. Note that there is a problem similar to the above for an occupant seated near a window such as a passenger seat (not shown) or a rear seat, and there is a need for a solution to the problem.

  In addition, as shown in FIG. 10, as a countermeasure against the window of the vehicle 121, a heat insulating member 123 can be installed outside the side glass 122 of the vehicle 121. However, when a film or the like is bonded as the heat insulating member 123 to the side glass 122 of the driver's seat or the passenger seat, the material used is also limited due to the problem of the visible light transmittance of the safety standard regarding the automobile window glass. In addition, since the film and the like are prepared, extra costs such as material costs and work costs are generated, and thus there is a problem that the measures are not very effective with respect to the above-described measures against cold and warm.

  The present invention has been made in view of the above circumstances, and the suction port of the vehicle air conditioner is disposed on the window side of the vehicle, and by flowing most of the conditioned air blown from the blowout port to the window side, The present invention relates to a vehicle air conditioner that reduces a temperature difference between a window side and a center side of a vehicle.

  Hereinafter, a vehicle air conditioner according to an embodiment of the present invention will be described in detail with reference to the drawings. In the description of the embodiment, the same reference numerals are used for the same members in principle, and repeated descriptions are omitted.

  FIG. 1 is a schematic side view for explaining a vehicle 1 in which a vehicle air conditioner 3 according to this embodiment is provided. FIG. 2 is a schematic configuration diagram for explaining the vehicle air conditioner 3 according to the present embodiment.

  As shown in FIG. 1, an air conditioning unit 7 of a vehicle air conditioner 3 is disposed in the back of the dashboard 2 of the vehicle 1. Air-conditioned air cooled or heated in the air-conditioning unit 7 is blown out into the passenger compartment through the air outlets 6R and 6L provided in the passenger seat 5. A pair of the air outlets 6R and 6L are arranged on the inner side and the outer side of the seat cushion 5A in the vehicle width direction. The vehicle air conditioner 3 is disposed, for example, on the passenger seat 5 and is used as a seat air conditioner. In addition, it replaces with the air-conditioning unit 7, and while using the existing HVAC (heating ventilation air conditioner), you may form a circulation air path by extending the duct connected to the said HVAC to the passenger seat 5. FIG.

  Although details will be described later, a suction port 24 (see FIG. 3B) is arranged on the upper end surface of the seat back 5B of the passenger seat 5 and closer to the window side of the vehicle 1 than the headrest 5C. The conditioned air blown from the air outlets 6R and 6L travels upward of the vehicle 1 along the thigh of the occupant P, and is then sucked from the air inlet 24. Then, the conditioned air sucked from the suction port 24 returns to the air conditioning unit 7 through the suction duct 8 disposed in the seat back 5B. On the other hand, the temperature of the returned conditioned air is adjusted in the air conditioning unit 7 or is blown out again from the outlets 6R and 6L through the air duct 9 while maintaining the temperature state.

  That is, most of the conditioned air blown out from the air outlets 6R and 6L is immediately sucked from the air inlet 24, so that the conditioned air in the passenger compartment circulates and the load on the vehicle air conditioner 3 is reduced. Energy saving operation is realized.

  In the following description, the case where the vehicle air conditioner 3 is disposed on the passenger seat 5 will be described. However, the present invention is not limited to this case. It may be arranged on a sheet.

  As shown in FIG. 2, the vehicle air conditioner 3 mainly includes air outlets 6R and 6L, a suction duct 8, a blower duct 9, a suction port 24, an air conditioning unit 7, a control unit 11, and a solar radiation sensor. 16, various sensors such as a room temperature sensor 17 and an outside air temperature sensor 18, and an operation switch 19. The air conditioning unit 7 includes a chamber 4, an intake duct 12, a blower 13, an evaporator 14, and a heat core 15.

  The control unit 11 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like, and is an electronic control unit that executes various calculations for vehicle air conditioning control ( ECU). And the control part 11 performs various calculations etc. based on the information detected from various sensors, such as the solar radiation sensor 16, the room temperature sensor 17, and the external temperature sensor 18, for example, and the present conditions, such as the room temperature condition in a vehicle interior, are shown now. It discriminate | determines and adjusts the blowing amount, the wind direction, etc. of the air-conditioning wind from each blower outlet 6R, 6L.

  The chamber 4 is disposed, for example, in the back of the dashboard 2 (see FIG. 1) of the vehicle 1, and a blower 13 and an intake duct 12 are disposed on the upstream side of the chamber 4. The intake duct 12 branches into an outside air intake duct 12A that takes in outside air and an inside air intake duct 12B that takes in inside air. Then, the outside air intake duct 12 </ b> A and the inside air intake duct 12 </ b> B are switched by the switching damper 20, and the air taken into the chamber 4 is selected. For example, when the blower 13 and the switching damper 20 are controlled by the control unit 11 and the blower 13 is driven by motor driving and the switching damper 20 closes the outside air intake duct 12A by motor driving, the inside air intake duct 12B is connected to the vehicle interior. The conditioned air is taken in.

  In the chamber 4, an evaporator 14 as a cooler unit and a heater core 15 as a heater unit are disposed from the upstream side. The evaporator 14 is arranged with respect to almost the entire cross section of the chamber 4, and the heat core 15 is arranged with respect to the cross section of about the upper half of the chamber 4. An air path adjustment damper 21 is disposed between the evaporator 14 and the heat core 15, and the air volume passing through the heat core 15 is adjusted by the air path adjustment damper 21. For example, the air path adjusting damper 21 is controlled by the control unit 11, and the air path adjusting damper 21 blocks the upper side of the chamber 4 by driving the motor, and the amount of air passing through the heat core 15 is reduced, so that the air path adjusting damper 21 blows out into the vehicle interior. The temperature of the conditioned air is lowered.

  A blower duct 9 is connected to the downstream side of the chamber 4, and the blower duct 9 branches into a right blower duct 9R and a left blower duct 9L in the seat cushion 5A (see FIG. 1). , 6L are provided. An air volume adjusting damper 22 is disposed at a branching location of the air duct 9, and the air volume adjusting damper 22 adjusts the flow area of the air duct 9, and the air volume of the conditioned air blown from the outlets 6R and 6L is adjusted. Yes. For example, the air volume adjusting damper 22 is controlled by the control unit 11, and when the right air duct 9R side on the air outlet 6R side is largely blocked by driving the motor, the air volume of the conditioned air blown from the air outlet 6L increases. .

  Although details will be described later, the air volume adjusting damper 22 is not necessarily limited to the case where it is disposed in the air duct 9, and, for example, a shutter or a louver for adjusting the air volume is disposed at the air outlets 6R and 6L. In this case, the air volume adjustment damper 22 may not be provided. Further, the air volume may be adjusted by combining the air volume adjusting damper 22 and the shutter or louver.

  The suction duct 8 is disposed in the seat back 5B (see FIG. 1), and a suction port 24 is provided at the tip thereof. And since the inlet 24 is arrange | positioned only on the outer side of the vehicle 1 with respect to the upper end part of the seat back 5B, most of the raised conditioned air flows toward the outer side of the vehicle 1.

  Various sensors such as a solar radiation sensor 16, a room temperature sensor 17, and an outside air temperature sensor 18 are disposed in the vehicle 1, and the sensors 16, 17, and 18 are connected to the control unit 11. The solar radiation sensor 16 is a sensor that detects the amount of solar radiation from the sun, the room temperature sensor 17 is a sensor that detects the air temperature inside the vehicle interior, and the outside air temperature sensor 18 is a sensor that detects the air temperature outside the vehicle interior. The control unit 11 performs various calculations based on information detected from the sensors 16, 17, 18, etc., and controls, for example, a motor that drives the switching damper 20, the air path adjustment damper 21, and the air volume adjustment damper 22. Adjust the temperature and air volume of the conditioned air.

  The operation switch 19 includes a push button, a rotation button, a touch panel, and the like, and is disposed on, for example, an instrument panel. The occupant P (see FIG. 1) can adjust the air conditioning mode, the air conditioning temperature, the wind direction, the air volume, and the like by operating the operation switch 19. And the operation switch 19 is connected to the control part 11, and according to operation of the operation switch 19 by the passenger | crew P, the control part 11 performs various control, the air-conditioning wind blown off from the temperature of an air-conditioning wind, and the blower outlets 6R and 6L The air volume etc. are adjusted.

  FIG. 3A is a perspective view for explaining the passenger seat 5 in which the vehicle air conditioner 3 of the present embodiment is disposed, and FIG. 3B is a diagram of the vehicle air conditioner 3 of the present embodiment. It is a top view for demonstrating the passenger seat 5 arrange | positioned.

  As shown in FIG. 3A, the passenger seat 5 includes a seat cushion 5A on which an occupant P (see FIG. 1) is seated, and a seat back 5B that extends upward from the rear of the seat cushion 5A and supports the back surface of the occupant P. The headrest 5C is disposed at the upper end of the seat back 5B.

  A pair of air outlets 6R and 6L are arranged on the upper surface side of the seat cushion 5A. The alternate long and short dash line indicates the center line 23 in the vehicle width direction of the passenger seat 5, but the pair of outlets 6 </ b> R and 6 </ b> L are disposed symmetrically in the vehicle width direction with respect to the center line 23 of the passenger seat 5. In addition, although the blower outlets 6R and 6L are formed as the opening part extended in the front-back direction of the vehicle 1, it is not limited to this shape. For example, a plurality of circular air outlets 6R and 6L smaller than the opening may be arranged in a line at regular intervals in the front-rear direction of the vehicle 1, and the entire upper surface of the seat cushion 5A is smaller than the opening. A plurality of circular outlets 6R and 6L may be arranged.

  The air duct 9 is disposed in the seat cushion 5A, and the conditioned air cooled or heated by the air conditioning unit 7 (see FIG. 2) is blown out from the air outlets 6R and 6L through the air duct 9 into the vehicle interior. The air outlets 6R and 6L are, for example, in the vicinity of the end portion on the upper surface side of the seat cushion 5A, and are disposed on a surface inclined toward the center line 23 side. Then, the conditioned air is blown out from the air outlets 6R and 6L upward of the vehicle 1 so as to wrap the lower body of the passenger P along the thigh of the passenger P.

  As shown in FIG. 3B, the height at which the suction port 24 is arranged is determined based on the body shape of the passenger P sitting on the passenger seat 5. As the body shape of the occupant P when determining the height, standardized body models AM50, AM95, etc. are appropriately adopted as a reference.

  Specifically, the pair of suction ports 24 is the upper end surface of the seat back 5B, and is disposed outside the vehicle 1 with respect to the headrest 5C. The suction port 24 is formed as an opening extending in the vehicle width direction of the vehicle 1. In the present embodiment, the suction port 24 is disposed on one side in the vehicle width direction of the vehicle 1 with respect to the upper end surface of the seat back 5B and the like, with respect to the center line 23 of the passenger seat 5. And the suction inlet 24 should just be arrange | positioned with respect to the said centerline 23, and the case where multiple are arrange | positioned at one side may be sufficient.

  Although the details will be described later, the suction port 24 is the upper end surface of the seat back 5B and is disposed on the side near the window, so that most of the conditioned air blown out from the air outlets 6R and 6L is left of the upper body of the occupant P. Flowing into. And the shoulder part and its vicinity by the window of the passenger | crew P can be cooled more actively in summer, and the shoulder part and its vicinity by the window of the passenger | crew P can be warmed more actively in winter.

  The height of the shoulder portion of the occupant P is the height from the base of the arm, that is, from the vicinity of the armpit that is the lower part of the connecting portion between the trunk and the arm, to the vicinity of the base of the neck. This corresponds to the height from the vicinity of the scapula to the vicinity of the base of the neck.

  First, a first example of the flow of conditioned air blown from the vehicle air conditioner 3 of the present embodiment will be described with reference to FIGS. 4 and 5. FIG. 4A is a front view for explaining the flow of the conditioned air blown from the vehicle air conditioner 3 of the present embodiment, and FIG. 4B is the suction of the vehicle air conditioner 3 of the present embodiment. FIG. 6 is a top view illustrating a mouth 24. FIG. 4C shows a cross-sectional view of the suction port shown in FIG. FIG. 5A is a top view illustrating the suction port 24 of the vehicle air conditioner 3 according to the present embodiment, and FIG. 5B illustrates the suction port 24 of the vehicle air conditioner 3 according to the present embodiment. FIG.

  As shown in FIG. 4A, an occupant P is seated on the passenger seat 5, and air outlets 6R and 6L of the vehicle air conditioner 3 are provided on the outer side and the inner side in the vehicle width direction of the vehicle 1 of the occupant P. Has been placed. Although details will be described later, the conditioned air blown out from the air outlets 6R and 6L is inclined obliquely upward toward the center of the occupant P by a louver 37 (see FIG. 6C) provided in the air outlets 6R and 6L. Blown out. As indicated by the arrow 26, the conditioned air flows along the thigh so as to wrap the lower body of the occupant P, and merges above the thigh at the center of the occupant P. Thereafter, as indicated by an arrow 27, the merged conditioned air flows upward of the vehicle 1 along the center of the occupant P. At this time, ascending airflow is generated around the occupant P due to heat generated from the occupant P, and the conditioned air blown out along the occupant P easily flows upward of the vehicle 1.

  As shown in FIG. 4B, a suction port 24 is arranged on the upper end surface of the seat back 5B on the outer side of the vehicle 1 than the headrest 5C. A movable shutter 28 is disposed at the suction port 24, and the shutter 28 slides in the vehicle width direction of the vehicle 1. In the shutter 28, for example, a substantially rectangular opening 29 shown by sand hatching is formed. The shutter 28 may be slid manually or may be controlled by the control unit 11 (see FIG. 2) and slid by a motor.

  As illustrated, in the suction port 24, all the openings 29 of the shutter 28 are located in the suction port 24. In this state, the opening area of the suction port 24 is the largest, and the amount of conditioned air sucked from the suction port 24 is maximized.

  Here, the vicinity of the window 32 of the vehicle 1 is in an environment where it is likely to become hot due to inflow of direct sunlight and external heat in the summer, and in the winter, it is likely to become cold due to the release of heat in the vehicle interior. This is a region where the temperature difference from the side tends to increase. Therefore, as shown in FIG. 4A, most of the conditioned air that has joined and risen at the center of the occupant P flows toward the suction port 24 as indicated by an arrow 30. As a result, a large amount of conditioned air is applied to the left shoulder portion of the occupant P near the window 32 of the vehicle 1 and the vicinity thereof, and the left shoulder portion and the periphery of the occupant P are actively heated or cooled. By doing so, the comfort of passenger | crew P is improved.

Further, as shown in FIG. 4 (C), the suction duct 8 below the shutter 28 of the suction port 24 has a
For example, a louver 34 that is rotatable in the front-rear direction of the vehicle 1 is disposed. By tilting the louver 34 toward the front of the vehicle 1, as shown by an arrow 30, the conditioned air rising along the front of the occupant P can be easily sucked from the suction port 24. Then, as indicated by the arrow 30, the conditioned air flows so as to wrap around the occupant P's neck, shoulders, and upper arms, and the comfort of the occupant P is enhanced. The louver 34 may be moved manually or controlled by the control unit 11 (see FIG. 2) and driven by a motor.

  As described above, in the vehicle air conditioner 3, the conditioned air blown from the outlets 6 </ b> R and 6 </ b> L flows so as to wrap the occupant P, and then is sucked from the suction port 24. The conditioned air sucked from the suction port 24 is temperature-adjusted in the air conditioning unit 7 and then blown out from the outlets 6R and 6L again. And when the vehicle air conditioner 3 is arrange | positioned for every sheet | seat of the vehicle 1, it becomes possible to adjust and use the air-conditioning temperature for every sheet | seat. In addition, most of the air-conditioning air whose temperature is adjusted in the air-conditioning unit 7 is circulated, so that the amount of divergence of the air-conditioning air whose temperature is adjusted is reduced, and the air-conditioning air is repeatedly circulated. And energy saving operation of the vehicle 1 is realized.

  In addition, although the case where the conditioned air sucked from the suction port 24 is sucked from almost the entire outlet 24 has been described, the present invention is not limited to this case. For example, as shown in FIG. 5A, the shutter 28 may be slid leftward in the vehicle width direction, and the left side of the suction port 24 (outside the vehicle 1) may be opened. In this case, the conditioned air flows away from the head of the passenger P toward the window 32 side of the vehicle 1. The conditioned air from the heating in the winter may directly touch the face, which may cause discomfort to the occupant P. The flow of the conditioned air is adjusted by the shutter 28, and the comfort of the occupant P is enhanced. On the other hand, as shown in FIG. 5B, the shutter 28 is slid to the right in the vehicle width direction, and the right side of the suction port 24 (the center side of the vehicle 1) may be opened. In this case, the conditioned air flows toward the head of the passenger P. The conditioned air from the cooling in the summer flows in the vicinity of the head of the occupant P, thereby enhancing the sensation of the occupant.

  In addition, as in the second embodiment described later, the air volume of the conditioned air blown out from the air outlets 6R and 6L may be varied. At this time, by increasing the amount of air blown from the air outlet 6R more than the air outlet 6L, a flow in which the conditioned air flows from the right side to the left side of the occupant P and envelops the entire body of the occupant P is realized. In particular, since the suction opening 24 is disposed only on the left side of the occupant P, it is easy to envelop the entire body of the occupant P by blowing a lot of conditioned air from the outlet 6R toward the upper side of the vehicle 1.

  Moreover, although the suction inlet 24 was the upper end surface of the seat back 5B and demonstrated the case where it arrange | positions on the outer side of the vehicle 1 rather than the headrest 5C, it is not limited to this case. For example, the suction port 24 may be the upper end surface of the seat back 5B and may be disposed closer to the center of the vehicle 1 than the headrest 5C. Usually, when the vehicle 1 is started in the winter, the interior of the vehicle is generally cooled. However, the direct sunlight may enter the window 1 so that it is warmer than the center side of the vehicle 1. In such a case, the body of the occupant P can be quickly warmed by flowing the conditioned air by heating to the center side of the vehicle 1.

  Next, a second example of the flow of conditioned air blown out from the vehicle air conditioner 3 of the present embodiment will be described with reference to FIGS. FIG. 6A is a front view for explaining the flow of the conditioned air blown from the vehicle air conditioner 3 of the present embodiment, and FIG. 6B is the blow of the vehicle air conditioner 3 of the present embodiment. It is a top view explaining exit 6R, 6L. FIG. 6C illustrates a cross-sectional view of the outlet shown in FIG. 6B in the BB line direction. In the description of the second embodiment, the first embodiment described above will be referred to as appropriate.

  As shown in FIG. 6 (A), the passenger seat 5 on which the occupant P is seated is provided with air outlets 6R, 6L on the upper surface of the seat cushion 5A on both sides of the occupant P, and the outer side of the vehicle 1 on the upper end surface of the seat back 5B. The suction port 24 is arranged in the front. The amount of conditioned air blown out from the outlets 6R and 6L can be adjusted, and as shown in the drawing, the outlet 6R can be closed and the conditioned air can be blown out only from the outlet 6L.

  Here, as shown in FIG. 6B, movable shutters 35R and 35L are disposed at the air outlets 6R and 6L, respectively, and the shutters 35R and 35L slide in the front-rear direction of the vehicle 1. Each of the shutters 35R and 35L is formed with a substantially rectangular opening 36L indicated by, for example, sand-like hatching. The shutters 35R and 35L may be manually slid or controlled by the control unit 11 (see FIG. 2) and slid by a motor.

  As illustrated, the opening of the air outlet 6R is completely blocked by the shutter 35R, and the conditioned air is not blown out from the air outlet 6R. On the other hand, in the air outlet 6L, the opening 36L of the shutter 35L is all located in the air outlet 6L. In this state, the opening area of the air outlet 6L is the largest, and the amount of conditioned air blown from the air outlet 6L is maximized.

  Further, as shown in FIG. 6C, for example, a louver 37 that is rotatable in the vehicle width direction of the vehicle 1 is disposed in the air ducts 9R and 9L below the shutters 35R and 35L of the outlets 6R and 6L. ing. By inclining the louver 37 in the vehicle width direction of the vehicle 1, the direction of the conditioned air blown out from the air outlets 6 </ b> R and 6 </ b> L can be adjusted.

  The air outlet 6R is completely closed by the shutter 35R. At the air outlet 6L, the three louvers 37 are directed in the vertical direction of the vehicle 1, so that the conditioned air is blown from the air outlet 6L as indicated by an arrow 38. From above the vehicle 1. On the other hand, the suction port 24 is disposed only on the outer side (left side) of the vehicle 1 at the upper end of the seat back 5B. And as shown in FIG.4 (B), the airflow volume of the air conditioned air suck | inhaled from the suction inlet 24 becomes the maximum.

  As a result, as indicated by an arrow 38, the conditioned air blown upward from the air outlet 6L to the upper side of the vehicle 1 rises on the left side of the occupant P, and most of the conditioned air is a suction port as indicated by an arrow 39. Inhaled from 24. In other words, an air layer formed by conditioned air is formed between the passenger P and the window 32. Even if external heat flows from the window 32 in the summer, the external heat hardly reaches the passenger P. The left shoulder and its surroundings are prevented from becoming too hot. In addition, the conditioned air by cooling flows around the left shoulder portion of the occupant P that is exposed to direct sunlight through the window 32 and the vicinity thereof, thereby cooling the occupant P's body and improving the comfort of the occupant P. . And it becomes easy to eliminate the temperature difference between the window side and the center side in the vehicle.

  Similarly, in winter, the air layer makes it difficult for heat in the passenger compartment to be released from the window 32, and the left shoulder of the passenger P and its surroundings are prevented from becoming too cold. In addition, the conditioned air by heating flows in the left shoulder portion and the vicinity of the occupant P, so that the body of the occupant P is warmed and the comfort of the occupant P is improved. In particular, when the vehicle 1 is traveling, heat in the passenger compartment is easily released to the outside of the vehicle through the window 32 due to the flow of air generated around the vehicle 1. The temperature difference is easily eliminated.

  Also in the second embodiment, the effect of circulating the air-conditioning air blown out from the air outlet 6L through the air inlet 24 and circulating in the vehicle air conditioner 3 is obtained as in the first embodiment described above. Moreover, although the description has been given of the case where the conditioned air is blown out only from the air outlet 6L and the conditioned air is sucked in from the suction port 24, the present invention is not limited to this case. For example, the opening degree of the air outlet 6R may be adjusted by the shutter 28R, and a portion of the conditioned air may be blown out from the air outlet 6R so that the conditioned air flows so as to wrap around the passenger P as in the first embodiment. . Further, as a means for closing the air outlets 6R, 6L, any one of the shutters 33R, 33L, the louver 37, the air volume adjusting damper 22 (see FIG. 2), or a combination thereof may be used.

  Next, a third example of the flow of conditioned air blown out from the vehicle air conditioner 3 of the present embodiment will be described with reference to FIG. FIG. 7 is a front view for explaining the flow of conditioned air blown out from the vehicle air conditioner 3 of the present embodiment.

  As shown in FIG. 7, on the passenger seat 5 on which the occupant P is seated, air outlets 6 </ b> R and 6 </ b> L are arranged on both sides of the occupant P. On the other hand, the suction port 40 is disposed on the roof 41 of the vehicle 1 above the occupant P seated on the passenger seat 5. The suction port 40 is disposed on the side of the window 32 of the vehicle 1 with respect to the center line 23 of the passenger seat 5 and is disposed only on the roof 41 near the roof side rail 42.

  And the structure of the suction inlet 40 is the same as that of the suction inlet 24 mentioned above, and it connects to the air-conditioning unit 7 of the vehicle air conditioner 3 via the suction duct (not shown) arrange | positioned in the side wall 33 of the vehicle 1. FIG. Connected. Although not shown, the suction port 40 is provided with a shutter and a louver. In addition, when the suction inlet 40 is arrange | positioned by the pillar (not shown) of the vehicle 1 above the shoulder part of the passenger | crew P who seated on the passenger seat 5, and the shoulder part above, the roof side rail 42, and the headrest 5C. But it ’s okay.

  As described above with reference to FIG. 6B, the opening degree of the air outlets 6R and 6L is adjusted by the shutters 35R and 35L, and the airflow direction of the conditioned air is adjusted by the louver 37. As shown by an arrow 43 in FIG. 7, most of the conditioned air is blown out from the air outlet 6R to the upper side of the vehicle 1, and as shown by an arrow 44, a part of the conditioned air is blown from the air outlet 6L. It is blown out to wrap the thigh. On the other hand, the amount of conditioned air sucked from the suction port 24 is maximized by adjustment by a shutter (not shown).

  Then, the conditioned air rising from the right side of the occupant P passes through the shoulder portion on the left side of the occupant P and the periphery thereof, and is sucked from the suction port 40 as indicated by arrows 45 and 46. As a result, a large amount of conditioned air is blown to the left shoulder portion of the occupant P near the window 32 of the vehicle 1 and the vicinity thereof, and the left shoulder portion and the periphery of the occupant P that is greatly affected by the window are actively warmed, Or the comfort of passenger | crew P is improved by cooling.

  In the third embodiment, the air volume from the air outlets 6R and 6L can be adjusted by circulation of the conditioned air and the shutter or the like, as in the first and second embodiments.

  Next, a fourth example of the flow of the conditioned air blown from the vehicle air conditioner 3 of the present embodiment will be described with reference to FIG. FIG. 8 is a front view for explaining the flow of conditioned air blown out from the vehicle air conditioner 3 of the present embodiment. In the description of the fourth embodiment, the first to third embodiments described above will be referred to as appropriate.

  As shown in FIG. 8, in the passenger seat 5 on which the occupant P is seated, air outlets 6 </ b> R and 6 </ b> L are arranged on both sides of the occupant P. On the other hand, the suction port 40 is disposed on the side of the window 32 of the vehicle 1 with respect to the center line 23 and is disposed only on the roof 41 near the roof side rail 42.

  Similar to the second embodiment described with reference to FIGS. 6A to 6C, the air outlet 6R is completely blocked by the shutter 35R, and at the air outlet 6L, the three louvers 37 are connected to the vehicle 1. As shown by the arrow 47 in FIG. 8, the conditioned air is blown out from the outlet 6 </ b> L above the vehicle 1 and toward the side wall 33 of the vehicle 1. On the other hand, the amount of conditioned air sucked from the suction port 40 is maximized by adjustment by a shutter (not shown).

  As a result, as indicated by arrows 48 and 49, the conditioned air blown obliquely upward of the vehicle 1 from the outlet 6L flows along the side wall 33 and the window 32 of the vehicle 1 to the upper side of the vehicle 1. Most of them are sucked from the suction port 40. That is, an air layer is formed by the conditioned air along the side wall 33 and the window 32 of the vehicle 1. And the effect by forming the said air layer is the same as that of 2nd Example, The description is abbreviate | omitted here.

  In the fourth embodiment as well, as in the first to third embodiments, the air flow from the air outlets 6R and 6L can be adjusted by circulation of the conditioned air and the shutter.
