  However, in the conventional air conditioner, for example, the hand that is close to the air outlet and the face that is far away have different effects on the thermal sensation of the occupant with the same conditioned air. There was a problem that it was difficult to make the face and hands comfortable at the same time, as the cold on the face was insufficient and the hands were too cold when matched to the facial sensation.

  Accordingly, an object of the present invention is to provide a vehicle air conditioner capable of blowing air blown from an air outlet toward a plurality of locations of an occupant in an optimal state.

In order to achieve this object, the present invention provides an air outlet opening in a vehicle interior, and right and left air in the vehicle width direction that is provided in the air outlet and is blown into the vehicle interior from the air outlet.

It is characterized by that.

  According to this invention, the air blown from the air outlet can be blown in an optimum state toward a plurality of locations of the occupant.

  For example, by changing the amount of wind blown to the passenger side of the passenger, particularly the driver holding the steering wheel, and the amount of wind blown to the passenger's face side at the same outlet, the distance from the outlet can be reduced. It is possible to make the occupant's hand and face comfortable at the same time by weakening the blowout to the near hand side and strengthening the blowout to the face far away from the blowout opening.

  Further, an IR sensor (occupant temperature) such as an IR camera for detecting the body temperature of the driver's seat occupant 6a, which is a test body, as shown in FIGS. Detection means) 28 is provided. The IR sensor 28 measures a heat conversion film that converts infrared rays incident from a temperature object to be heated into heat, a detection element that converts heat converted by the heat conversion film into electric power, and a temperature in the sensor.

At this time, as shown in Table 1 below, the air volume ratio of the blowing air applied to the face 6aF and the hand 6aH is as follows.

となる。

It becomes.

In addition, detection signals from the sensors Sh and Sv are input to the microcomputer 30. Further, the microcomputer 30 controls the driving of the fin drive motors 21 and 22. The microcomputer 30 is connected to an ignition switch Sw1 of the vehicle 1 and an air conditioning power switch Sw2 of the air conditioner main body AC.
[Action]
Next, the control of the vehicle air conditioner by the microcomputer 30 will be described based on the flowchart of FIG.

  First, the operation knob 23 is operated so that the direction of the vertical deflection louver 18 is substantially horizontal. On the other hand, the operation knob 23 is operated to turn the lateral deflection louver 17 toward the driver's seat occupant 6a. In this state, the wind (air) blown out from the air outlet 16a into the passenger compartment 3 is blown toward the hand 6aH and the face 6aF of the driver's seat occupant 6a while diffusing.

  When the power source of the vehicle 1 (ignition switch Sw1 or air conditioning power switch Sw2 of the air conditioner) shown in FIG. 1 is turned on, first, in step S1, timers, counters, and flags used for subsequent processing are initialized. The initialization process is executed, and the process proceeds to step S2.

  On the other hand, when the power is turned on, the IR sensor (IR camera) 28 operates, and the upper body of the driver's seat occupant 6a, the handle H, and the like are imaged by the IR sensor (IR camera) 28. An image (thermal image) captured (acquired) by the IR sensor (IR camera) 28 is output as an image signal (detection signal), and this image signal is input to the microcomputer 30. In the state where the air conditioning power switch Sw2 is ON, the air conditioned by the air conditioner main body AC is supplied to the duct 24. Then, the air supplied to the duct 24 is blown out from the air outlet 16 a of the center air blowing device 15 toward the inside of the passenger compartment 3. Wind (air) blown out from the air outlet 16a into the passenger compartment 3 is blown toward the hand 6aH and face 6aF of the driver's seat occupant 6a.

  Next, in step S2, the microcomputer 30 detects the position and temperature of the face 6aF and hand 6aH of the driver's seat occupant 6a from the image signal (detection signal) input from the IR sensor (IR camera) 28, and the process proceeds to step S3. Transition.

  In this example, the case where the face 6aF and the hand 6aH of the driver's seat occupant 6a are processed by one IR sensor 28 installed as shown in FIGS. 1 and 3 as shown by the broken line 29 in FIG. State. Note that any method may be used for detecting the face 6aF and the hand 6aH of the driver's seat occupant 6a, who is the driver's seat occupant, and a temperature range of 30 ° C to 35 ° C close to the surface temperature of the human body is extracted as a region, and then the pattern is extracted. The face and hand may be specified by matching, and the average temperature of each region may be the detection temperature, and the center of gravity of each region may be the detection position.

  In step S3, the microcomputer 30 performs a branching process according to the presence or absence of the driver's seat occupant 6a based on the output result of step S2. That is, when the face area of the driver's seat occupant 6a is detected by the IR sensor 28 in step S2, it is determined that the driver's seat occupant 6a is present, and the process proceeds to the next step S4, where there is no driver's seat occupant 6a. To step S14.

  Next, in step S4, if the air conditioning power switch Sw2 of the air conditioner main body AC is turned on, the microcomputer 30 determines the position of the lateral wind direction deflecting fin 17a (turning fin) of the lateral deflecting louver 17 (the tilt position in the vehicle width direction, That is, branch processing based on the direction of the driver's seat occupant 6a) is performed. That is, if the air conditioning power switch Sw2 of the air conditioner main body AC is ON and the blowing direction is directly facing the driver's seat occupant 6a, the process proceeds to the next step S5, and if not, the process proceeds to step S14. Transition. The direction of the horizontal wind direction deflection fin 17a is determined based on a position detection signal from the sensor Sh.

  In step S5, the microcomputer 30 performs a branching process based on the position of the hand 6aH of the driver's seat occupant 6a detected in step S2. That is, if the position of the hand 6aH of the driver's seat occupant 6a is near the handle H, the process proceeds to the next step S6, and if the position of the hand 6aH of the driver's seat occupant 6a is not near the handle H, the process proceeds to step S14.

  Next, in step S6, the microcomputer 30 detects the temperature of the handle H and proceeds to step S7. That is, the microcomputer 30 defines the region (position) of the handle H in the IR sensor image based on the mounting position of the IR sensor 28 to the vehicle, and detects, for example, the average temperature of the region as the temperature of the handle H, step S7. Migrate to

  In step S7, the microcomputer 30 calculates the temperature difference ΔF_H between the face 6aF of the driver occupant 6a and the hand 6aH by subtracting the temperature of the hand 6aH of the driver occupant 6a from the face 6aF of the driver occupant 6a. Transition.

  Next, in step S8, the microcomputer 30 performs a branch process based on ΔF_H calculated in step S7.

  That is, when the temperature difference ΔF_H between the face 6aF of the driver's seat occupant 6a and the hand 6aH is larger than a predetermined value TH_H (for example, 5 ° C.), that is, the temperature of the face 6aF of the driver's seat occupant 6a If the temperature of the hand 6aH is considerably higher than the temperature of the hand 6aH, the process proceeds to the next step S9. To do.

  In step S9, the microcomputer 30 performs a branching process based on the temperature of the handle H detected in step S6. That is, the microcomputer 30 proceeds to step S12 if the temperature of the handle H is lower than a predetermined value TH_STR (for example, 35 ° C.), and proceeds to step S13 if the temperature of the handle H is equal to or higher than the predetermined value TH_STR.

  When the temperature difference ΔF_H between the temperature of the handle H and the hand 6aH is large, the temperature of the hand 6aH is affected by the temperature of the handle H. In order to avoid this, when the difference between the temperature of the handle H and the temperature of the hand 6aH is large, the air volume in the handle direction (that is, the air volume in the direction of the hand 6aH) is increased so that the temperature of the handle H becomes a predetermined value or less. Good.

  Therefore, in step S10, the microcomputer 30 performs a branch process based on ΔF_H calculated in step S7 as in step S8. That is, since ΔF_H is equal to or less than the predetermined value TH_H in step S8, the microcomputer 30 compares it with the predetermined value TH_L in step S10. When the temperature difference ΔF_H between the face 6aF of the driver seat occupant 6a and the hand 6aH is larger than a predetermined value TH_L (for example, 2 ° C.), that is, the temperature of the face 6aF of the driver seat occupant 6a is the temperature of the hand 6aH of the driver seat occupant 6a. If the temperature difference ΔF_H between the face 6aF of the driver's seat occupant 6a and the hand 6aH is equal to or smaller than a predetermined value TH_L (for example, 2 ° C.), the process proceeds to step S14.

  Next, in step S11, branch processing is performed based on the result of the handle H detected in step S6 as in step S9. That is, the microcomputer 30 proceeds to step S13 if the temperature of the handle H is lower than a predetermined value TH_STR (for example, 35 ° C.), and proceeds to step S14 if the temperature of the handle H is equal to or higher than the predetermined value TH_STR.

  In step S12, the microcomputer 30 increases the wind WA1 in the outer blowing area Wo that hits the face 6aF of the driver's seat occupant 6a and the wind WA2 in the inner blowing area Wi that hits the hand 6aH of the driver's occupant 6a as shown in FIG. In order to weaken, the opening area of the inflow portion 25a1 of the end passage 25a for the wind WA1 hitting the face 6aF side and the opening area of the inflow portion 25a2 of the end passage 25a for the wind WA2 hitting the hand 6aH side The ratio is set to 3: 1 and the process proceeds to step S15.

  Further, in step S13, the microcomputer 30 causes the face WAa that hits the face 6aF of the driver occupant 6a to be slightly stronger and the wind WA2 that hits the hand 6aH of the driver occupant 6a to be slightly weaker as shown in FIG. 9B. The ratio of the opening area of the inflow portion 25a1 of the end passage 25a for the wind WA1 hitting the side to the opening area of the inflow portion 25a2 of the end passage 25a for the wind WA2 hitting the hand is set to 2: 1. Proceed to step S15.

  Further, in step S14, the microcomputer 30 hits the face side in order to equalize the wind WA1 hitting the face 6aF of the driver seat occupant 6a and the wind WA2 hitting the hand 6aH of the driver seat occupant 6a as shown in FIG. 9C. The ratio of the opening area of the inflow portion 25a1 of the end flow passage 25a for the wind WA1 to the opening area of the inflow portion 25a2 of the end flow passage 25a for the wind WA2 that hits the hand is set to 1: 1. The process proceeds to S15.

 In step S15, the microcomputer 30 outputs the ratio of any opening area set in step S12, step S13, or step S14, and proceeds to the next step 16.

  Next, in step S16, the microcomputer 30 controls the partition plate drive motor 27 in FIG. 5A to perform normal rotation or reverse drive so that the ratio of the opening area based on the output signal in step S15 is reached. The rotation of the shut valve 26 is controlled clockwise or counterclockwise, and the process proceeds to step S17. At this time, the direction of the movable partition plate 26 is detected by the sensor S, and when the ratio of the opening area based on the output signal in step S15 is reached, the drive of the partition plate drive motor 27 is stopped.

  Finally, in step S17, the microcomputer 30 performs a branching process based on whether or not the air conditioning power switch Sw2 of the air conditioner main body AC is turned off. That is, if the air conditioning power switch Sw2 is not turned off, the microcomputer 30 returns to step S2 and loops. If the air conditioning power switch Sw2 is turned off, the microcomputer 30 ends the program.

  As described above, in the present embodiment, the amount of wind WA2 blown to the hand 6aH side of the occupant, particularly the driver seat occupant (driver) 6a holding the handle H, and the wind blown to the face 6aF side of the driver seat occupant 6a. By making the amount of WA1 variable at the same air outlet 16a, the blowout to the hand 6aH side where the distance from the air outlet 16a is near is weak and the distance from the air outlet 16a is far to the face 6aF. Since the balloon can be strengthened, the hand 6aH and the face 6aF of the driver's seat occupant 6a can be made comfortable at the same time.

In the above-described embodiment, the direction (position) of the wind direction deflection fins 17a and 18a can be deflected by the fin drive motors 21 and 22. However, the fin drive motors 21 and 22 are not necessarily required.
(Modification 1)
In the embodiment described above, only the control of the movable partition plate 26 has been described. However, the present invention is not necessarily limited to this control.

  For example, when a switch for face mode, hand mode, face hand mode, etc. is provided and the face hand mode switch is pressed, the fin drive motors 21, 22 are driven and controlled from the air outlet 16a. The direction of the blown wind can be blown most effectively toward the face 6aF and the hand 6aH of the driver's seat occupant 6a.

  When the face mode switch is pressed, the fin drive motors 21 and 22 are driven and controlled, and the direction of the wind blown from the air outlet 16a is most effective toward the face 6aF of the driver's seat occupant 6a. At the same time, the air blown from the air outlet 16a can also be blown to the hand 6aH.

  Furthermore, when the hand mode switch is pressed, the fin drive motors 21 and 22 are driven and controlled, and the direction of the wind blown from the air outlet 16a is most effective toward the hand 6aH of the driver's seat occupant 6a. At the same time, the air blown from the air outlet 16a can also be blown to the hand 6aH.

During such driving, the microcomputer 30 detects the direction (position) of the vertical wind direction deflection fin 18a of the vertical deflection louver 18 by the sensor Sv, and when the direction (position) of the vertical wind direction deflection fin 18a reaches a predetermined angle. Then, the drive of the fin drive motor 22 is stopped.
(Modification 2)
Further, in addition to the above-described control, the forward and reverse drive control of the fin drive motor 21 is performed to change the direction of the wind blown from the air outlet 16a in the vehicle width direction, so that the wind hits the driver's seat occupant 6a. The state may be changed.

In addition to this control, the forward and reverse drive control of the fin drive motor 22 is performed to change the direction of the wind blown from the air outlet 16a in the vertical direction so that the wind hits the driver's seat occupant 6a. It may be changed. In this case, since the direction of the wind blown from the air outlet 16a changes in the vehicle width direction and the vertical direction, the wind blown from the air outlet 16a is used as the hand 6aH and the face 6aF of the driver seat occupant 6a and the upper body. Can be sprayed over a wide range in better condition.
(Modification 3)
FIGS. 10A and 10B show a mechanical mechanism that determines the position of the movable partition plate 26 based on the position of the wind direction deflection fins (turning fins) 17a of the lateral deflection louver 17. Reference numeral 17b denotes a link of the lateral deflection louver 17 as described above.

  As shown in FIG. 10A, a gear 26b is fixed to the rotating shaft 26a of the movable partition plate 26, a rack 17d is attached to the front surface of the link 17b in the vehicle front-rear direction, and a rack 17d is installed in the duct 24. The gear 31 is attached so as to be rotatable in the vicinity of the gear 31. The gear 31 is located in the center of the duct 24 in the width direction, and is made to correspond to the gear 26 b in the width direction of the duct 24.

  A rack mounting member 32 oriented in the vehicle front-rear direction is disposed in the duct 24. Guide slits 33 and 33 are formed at both ends of the rack mounting member 32 in the vehicle front-rear direction, and guide pins 34 and 34 fixed to the duct 24 are inserted into the guide slits 33 and 33. The guide pins 34 and 34 are provided so as to be relatively movable in the longitudinal direction of the guide slits 33 and 33 and immovable in the width direction.

  Further, both end portions of the rack mounting member 32 are brought close to the gears 26b and 31, and racks 32a and 32b facing the gears 26b and 31 are attached to both end portions of the rack mounting member 32.

  In addition, as shown in FIG. 10 (a), the rack 17d and the gear 31 do not mesh with each other at the position where the horizontal wind direction deflection fins 17a are parallel to the vehicle longitudinal direction without being inclined (neutral state). It has become. Further, the operation knob (wind direction adjusting lever) 23 is moved to the left in the figure as shown by an arrow 35 from the position outside this position, that is, the position shown in FIG. 10A, and the horizontal wind direction deflecting fin 17a is rotated clockwise. Even if it is rotated in the direction, the rack 17d and the gear 31 are not engaged (neutral state).

  Further, when the occupant moves the operation knob (wind direction adjusting lever) 23 from the position in FIG. 10A to the right side as indicated by the arrow 36, the operation knob 23 moves to the right side as shown in FIG. 10B. At the same time, the lateral wind direction deflection fins 17a are rotated counterclockwise and directed toward the passenger.

  At this time, the rack 17d rotates the gear 31 in the clockwise direction, and the gear 31 moves the rack 32b to the rear of the vehicle. Along with this, the rack mounting member 32 is moved to the rear of the vehicle together with the rack 32b, and the rack 32a of the rack mounting member 32 rotates the gear 26b in the clockwise direction.
