Description

  The present invention relates to a vehicle interior air conditioning method and an air conditioner that can comfortably air-condition (heat) a rear seat side in a vehicle interior of a vehicle.

  For heating the passenger compartment, some warm air is blown out from the face outlet or differential outlet provided on the instrument panel. To ensure a sense of heating. For this reason, heating of the upper body and knees depends on temperature mixing by natural convection due to the buoyancy of hot air, but temperature mixing by natural convection is difficult to control, and heating of the upper body and knees is insufficient. It was apt. In particular, in a wide vehicle type such as a minivan, the tendency is remarkable on the rear seat side. Further, if the amount of hot air blown from the face outlet or the differential outlet is simply increased, the hot air tends to stay upward due to buoyancy, and problems such as hot flashes will occur.

  In Patent Document 1, as an air conditioning system suitable for air conditioning of a one-box car or the like, a front air conditioner unit provided with a louver that guides the blowing air from the instrument panel outlet and the blowing air from the ceiling outlet is guided forward. There is disclosed an air conditioning system that is provided with a rear air conditioner unit that is provided with a louver so as to collide with the air blown from both air outlets so that the air blow does not directly hit the passenger. Japanese Patent Application Laid-Open No. H10-228561 discloses an arrangement in which a vertical louver and a left and right louver are provided at the air outlet, and the deflection angle is controlled so that the temperature in the vicinity of the occupant's head and the leg becomes a predetermined temperature difference. Has been. Further, Patent Document 3 discloses a device in which a front air direction adjusting plate and a rear air direction adjusting plate are provided at the air outlet, and the air flow is directed to a desired portion in a point manner.

Japanese Patent No. 3575119 JP 2000-247139 A JP 2009-23530 A

  As described above, it is possible to blow warm air directly to the feet by passing a duct under the floor, but it is difficult to blow warm air directly to the upper body or knee. Therefore, the upper body and knees need to be heated by the mixed diffusion of warm air, but the mixed diffusion of warm air by natural convection is difficult to control the airflow, so the influence of buoyancy is relatively small. Mixed diffusion of warm air by forced convection is desirable. However, as disclosed in Patent Document 1, even if another air conditioner unit is provided on the rear side and hot air is blown out from the ceiling outlet and forced convection is performed, only the head and face of the upper body are heated, resulting in discomfort A comfortable feeling of heating cannot be obtained.

  In addition, if the flow rate is high enough to make a draft feel with warm air, people will feel uncomfortable, so either suppress the flow rate of the warm air around the human body or prevent the warm air from directly hitting the passenger. There is a need. Patent Documents 2 and 3 disclose that the upper and lower louvers and the left and right louvers are provided at the front and rear of the air outlet to control the blowout air in various ways, but the temperatures blown from the face air outlet and the differential air outlet are disclosed. It does not attempt to promote the mixing and diffusion of warm air by directing the wind to the passengers without passing directly to the passenger.

  The present invention has been made in view of such circumstances, and distributes the warm air blown from the air outlets provided on both sides of the instrument panel throughout the vehicle interior without directly hitting the passenger. Another object of the present invention is to provide a vehicle interior air conditioning method and apparatus that can promote the diffusion mixing and improve the feeling of heating.

In order to solve the above-described problems, the vehicle interior air conditioning method and apparatus of the present invention employ the following means.

A louver that can be fixed in a direction that collides with the pillar is provided, and the warm air blown from the outlet through the louver is caused to collide with the center pillar to flow toward the center in the width direction of the vehicle interior. After turning around, the warm air is merged near the center in the width direction of the passenger compartment through the back of the front seat, then flows backward through the center of the width direction of the rear seat, and the hot air collides with the rear window to the left and right. The warm air that has flowed sideways along the rear window is flowed from the rear to the front side along the rear side window, so that the warm air is directly applied to the passenger. Characterized by heating the entire passenger compartment without.

  According to the present invention, the position of the louver provided at the air outlet is fixed in the direction in which the blown warm air collides with the center pillar, the warm air is blown out along the side window, and the warm air is blown off to the center pillar. To the center of the vehicle interior in the width direction, and the warm air is merged near the center of the vehicle interior through the rear of the front seat and then rearward through the center of the rear seat in the width direction. The warm air is made to collide with the rear wind and split to the left and right, and the warm air that flows laterally along the rear wind is passed from the rear to the front side along the rear side window, thereby directly It can be distributed throughout the vehicle interior without being exposed to the air, and can be heated by promoting the mixing and diffusion of hot air by forced convection. Therefore, it is possible to improve the feeling of heating by increasing the temperature of the entire passenger compartment while suppressing the draft feeling due to warm air.

  Furthermore, in the vehicle interior air conditioning method according to the present invention, when the louver is movably adjusted in the vehicle interior air conditioning method, the louver controls the warm air via a louver position control means provided at the air outlet.

Therefore, when the louver at the air outlet is moved to distribute the hot air throughout the vehicle compartment including the rear seat side, the hot air is blown in the direction in which the louver collides with the center pillar via the louver position control means. By fixing at the position to be taken out, it is possible to blow out the warm air in a direction in which the hot air reliably collides with the center pillar. Therefore, anyone can make the warm air collide with the center pillar by a simple operation of the louver, distribute the warm air throughout the vehicle interior in the above flow pattern, promote the mixing and diffusion, and obtain a comfortable heating feeling. it can.

  The vehicle interior air conditioning method of the present invention is the vehicle interior air conditioning method described above, wherein the louver is automatically moved via an air conditioning controller by manual operation of an operation button or the like or detection of a set outside air temperature, and the louver The hot air can be fixed at a position where it blows out in the direction of collision with the center pillar.

  According to the present invention, the louver is automatically moved via the air conditioning controller by manual operation of the operation means or the detection of the set outside air temperature, and blows out the louver in a direction in which the warm air collides with the center pillar. Since the position can be fixed, the louver can be moved through the air conditioning controller by manual operation of the operation button or the detection of the outside air temperature, and the louver is automatically warmed in the direction of colliding with the center pillar. It can be fixed at a position where the wind is blown out. Therefore, the movement and fixing of the louver to the position where the hot air is blown in the direction of colliding with the center pillar can be automated, and the mixing and diffusion of hot air by forced convection can be promoted by improving operability and operation accuracy. A more comfortable heating feeling can be obtained in the entire vehicle interior.

  Furthermore, in the vehicle interior air conditioner according to the present invention, a louver capable of adjusting the direction of air-conditioning air is installed at a side face air outlet, a side differential air outlet, or a dedicated air outlet provided on both sides of the instrument panel. In the vehicle interior air conditioner, the louver position control means capable of fixing the conditioned air to a position where the conditioned air is blown out in a direction of colliding with the center pillar protruding toward the vehicle interior side. It is provided.

  According to the present invention, in the air conditioner in which the louver capable of adjusting the blowing direction of the conditioned air is installed at the side face air outlet, the side differential air outlet, or the dedicated air outlet provided on both sides of the instrument panel. The louver is provided with louver position control means capable of fixing the conditioned air at a position where the conditioned air is blown out in the direction of colliding with the center pillar protruding toward the vehicle interior side. When conditioned air (warm air) is circulated throughout the vehicle interior including the rear seat side by moving the louver, the louver blows out the warm air toward the center pillar through the louver position control means. The hot air from the air outlet can be blown out in the direction of colliding with the center pillar along the side window. The air flow is turned to the center in the width direction of the passenger compartment, and the warm air passes through the back of the front seat and merges in the vicinity of the center of the width of the vehicle, and then flows backward through the center of the rear seat in the width direction. The hot air is collided with the rear window and diverted to the left and right, and the hot air that flows laterally along the rear window flows from the rear to the front side along the rear side window, thereby directly It can be circulated throughout the entire interior of the vehicle without being exposed to, and can be heated by promoting mixed diffusion by forced convection. Therefore, it is possible to increase the temperature of the entire vehicle interior and improve the feeling of heating while suppressing the draft feeling due to warm air.

  Furthermore, in the vehicle interior air conditioner according to the present invention, in the vehicle interior air conditioner, the louver position control means is provided at the air outlet and faces the direction of colliding with the center pillar when moving the louver. It is characterized in that any one of a protrusion, a stopper, a mark, and the like that can fix the louver at a position where the conditioned air is blown out is provided.

  According to the present invention, the louver position control means is provided at the air outlet, and when the louver is moved, the protrusion, stopper or mark that can fix the louver to the position where the conditioned air is blown out in the direction of colliding with the center pillar. Therefore, when moving the louver so that the direction of the air-conditioned air blows against the center pillar, it is necessary to move the louver to a position where it touches the protrusion or stopper or a position where the mark matches. In particular, the blowing direction of the conditioned air (warm air) by the louver can be set to the direction of colliding with the center pillar. Therefore, anyone can make the warm air collide with the center pillar by a simple operation of the louver, distribute the warm air throughout the vehicle interior in the above flow pattern, promote the mixing and diffusion, and obtain a comfortable heating feeling. it can.

A louver moving mechanism is provided which is movable to a position where the conditioned air is blown out in a collision direction.

  According to the present invention, the louver is moved to a position where the louver blows out the conditioned air toward the direction of colliding with the center pillar through the air conditioning controller by manual operation of the operation button or the like or detection of the set outside air temperature. Since it has a movable mechanism, the louver can be automatically collided with the center pillar by operating the louver movable mechanism via the air conditioning controller by manual operation of the operation buttons or the like or detection of the set outside air temperature. It can be moved and fixed at the position where the conditioned air (warm air) is blown. Therefore, the movement and fixing of the louver to the position where the hot air is blown in the direction of colliding with the center pillar can be automated, and the mixing and diffusion of hot air by forced convection can be promoted by improving operability and operation accuracy. A more comfortable heating feeling can be obtained in the entire vehicle interior.

  Furthermore, the vehicle interior air conditioner according to the present invention is the vehicle interior air conditioner according to any one of the above, wherein the center pillar has a front side surface where the air conditioned air collides with the air conditioned air in the width direction center side of the vehicle interior. It is characterized by being a concave arcuate surface that turns toward the surface.

The conditioned air (warm air) can be smoothly turned toward the center in the width direction of the passenger compartment by the concave arc surface, reducing the turbulence caused by flow separation and others, and suppressing the diffusion of hot air can do. Accordingly, it is possible to improve the reachability of the warm air to the downstream side (rear seat side) and reduce the required air volume. In addition, since the flow of warm air along the side window can be reliably turned to the center side in the width direction of the passenger compartment, the warm air hits the occupant on the rear seat side, particularly near the face. Can be prevented.

  According to the vehicle interior air-conditioning method and apparatus of the present invention, the hot air blown from the air outlets on both sides of the instrument panel collides with the center pillar and is turned toward the center in the width direction of the vehicle interior. Since warm air can be circulated throughout the vehicle interior without directly hitting the passengers, mixing and diffusion by forced convection can be promoted for heating, the temperature of the entire vehicle interior can be increased while suppressing the draft feeling due to hot air. , The feeling of heating can be improved.

As shown in FIG. 1, the vehicle interior 1 of the vehicle has a substantially rectangular planar shape, and is provided with an instrument panel 2 at the front, and a driver's seat (front seat) 3 and an assistant on the rear side. A seat (front seat) 4 is disposed, and left and right rear seats 5 and 6 are disposed on the rear side. The rear seats 5 and 6 may be arranged in two rows in the front and rear in a minivan, a one-box car, or the like.

  In the vehicle air conditioner, an HVAC unit (Heating Ventilation and Air Conditioning Unit) is usually provided in the instrument panel 2, and the temperature-controlled air (cold air or hot air) adjusted in temperature in the HVAC unit is From the center face air outlet and the side face air outlets provided at the center and both sides of the front surface of the instrument panel 2, the air is blown toward the rear of the vehicle interior 1 and is opened on the upper surface of the instrument panel 2. It blows out toward the front window 7 from the differential blower outlet, and is further blown out from the foot blower outlet provided at the lower part of the HVAC unit to the vicinity of the passenger's feet.

  FIG. 3 shows side face air outlets 8 and 9 provided on both sides of the front surface of the instrument panel 2 and side differential air outlets 10 and 11 provided on the upper surface of the instrument panel 2. . Among these air outlets, in particular, a center face air outlet (not shown) and side face air outlets 8 and 9 provided on the front surface of the instrument panel 2, as shown in FIG. A plurality of left and right louvers 12 and upper and lower louvers 13 whose directions are adjusted in the left-right direction and the up-down direction are provided so as to be rotatable every plurality. The left and right louvers 12 and the upper and lower louvers 13 are rotatable via louver position adjusting knobs 14 and 15 provided in the vicinity of the side face outlets 8 and 9.

  Further, in the present embodiment, the left and right louvers 12 and the upper and lower louvers 13 are arranged around the side face outlets 8 and 9, and the temperature-controlled air blown from the side face outlets 8 and 9 is centered along the side window 16. Marks 18A, 18B and 19A, 19B for moving and fixing are provided at positions where they are blown out in the direction of collision with the pillar 17. The marks 18A, 18B and 19A, 19B as the louver position control means are provided in pairs between the louver position adjusting knobs 14 and 15 side and the instrument panel 2 side.

  The center pillar 17 is arranged between the front door on the front seats 3 and 4 side and the rear door on the rear seats 5 and 6 and between the roof side rail on the roof panel side and the side sill on the floor panel side. It is a member that is installed in the direction and secures the strength of the body, and is composed of an outer member that is disposed on the outer side in the vehicle width direction and an inner member that is disposed on the inner side. The inner member has a U-shaped cross-sectional shape and is formed into a hollow columnar member by being coupled to the outer member so as to protrude into the vehicle interior 1.

  Further, the marks 18A, 18B and 19A, 19B as the louver position control means are directions in which the warm air blown from the side face outlets 8, 9 collides with the center pillar 17 along the side window 16 as described above. The left and right louvers 12 and the upper and lower louvers 13 or the louver position adjusting knobs 14 and 15 may be replaced with protrusions or stoppers that can be stopped and fixed with a click feeling.

  Further, instead of manually adjusting the left and right louvers 12 and the upper and lower louvers 13 to the above positions, a dedicated operation button is provided on an air conditioning controller (not shown) and the operation button is operated, or the air conditioning controller By detecting the outside air temperature below a certain temperature (for example, 0 ° C. or below) with the outside air temperature sensor provided in the left and right louvers 12, the left and right louvers 12 and the upper and lower louvers 13 are connected via an air conditioning controller and an actuator (not shown) such as a motor. It may be driven directly or via a link mechanism (not shown), and may be moved and stopped at a position where the warm air can be blown in the direction of colliding with the center pillar 17 as described above.

Next, the air-conditioning method in the passenger compartment 1 by the above-described air conditioner will be described.
The temperature control air blowing mode in an air conditioner using a general HVAC unit is a face mode in which temperature control air is blown out from the face air outlet, a foot mode in which air is mainly blown out from the foot air outlet, and a differential mode in which air is blown out from the differential air outlet. The bi-level mode that blows out from both the face outlet and the foot outlet, and the differential / foot mode that mainly blows out from the differential outlet and also from the foot outlet can be set. One of the normal foot mode, the bi-level mode, and the differential foot mode is selected.

  If the outside air temperature is low during heating operation, a sufficient feeling of heating may not be obtained particularly on the rear seats 5 and 6 side. In this case, heating only the upper body and knees tends to be inadequate only by blowing out warm air from the feet. Therefore, the foot mode with blowing from the side face outlet, the differential foot mode, or the bi-level mode with blowing from the differential outlet is selected, and hot air is blown out from the side face outlets 8 and 9 as well. Like that. At this time, the warm air blown from the side face air outlets 8 and 9 collides with the center pillar 17 along the side window 16 through the left and right louvers 12 and the upper and lower louvers 13 provided at the side face air outlets 8 and 9. Rotate to the position where it blows out in the direction.

  The rotating operation of the left and right louvers 12 and the upper and lower louvers 13 to the above-described positions is a method of moving the louver position adjusting knobs 14 and 15 to positions where the marks 18A, 18B and 19A and 19B coincide with each other, the left and right louvers 12 and the upper and lower louvers. 13 or a method in which the louver position adjusting knobs 14 and 15 are moved to a position where a click feeling can be obtained by hitting a protrusion or a stopper, and the outside air temperature sensor detects an outside air temperature below a set temperature by manual operation of an operation button. Thus, a method of automatically moving the left and right louvers 12 and the upper and lower louvers 13 to the above positions via an air conditioning controller and an actuator is used.

  In this way, the warm air blown from the side face outlets 8 and 9 can be blown out in the direction of colliding with the center pillar 17. As shown in FIG. 1, the hot air first collides with the front side surface of the center pillar 17 protruding into the vehicle interior 1, and the flow is turned to the center in the width direction of the vehicle interior 1. This warm air flows through the rear of the front seats 3 and 4 toward the center in the width direction of the vehicle interior 1 and merges in the vicinity of the center in the width direction. The merged warm air flows backward through the center in the width direction of the passenger compartment 1 between the left and right rear seats 5, 6, and is divided into left and right by colliding with the rear window 20. Further, the warm air is caused to flow along the rear window 20 to the side of the vehicle interior 1, and then flows along the rear side window 21 to the front side.

Thereby, the hot air blown out from the side face outlets 8 and 9 along the side window 16 collides with the center pillar 17 to change the flow direction, and the hot air is directly applied to the occupant by the above flow pattern. And can be distributed throughout the vehicle interior 1. As a result, the mixing and diffusion of warm air by forced convection can be promoted to heat the vehicle interior 1.
Therefore, according to the vehicle interior air conditioning method and apparatus according to the present embodiment, it is possible to increase the temperature of the entire vehicle interior 1 and improve the feeling of heating while suppressing the draft feeling due to warm air.

  Further, when the left and right louvers 12 and the upper and lower louvers 13 are moved so that the blowing direction of the warm air collides with the center pillar 17, the marks 18A, 18B and 19A, 19B as louver position control means, or protrusions, stoppers, etc. The left and right louvers 12 and the upper and lower louvers 13 are inevitably moved to positions where the marks 18A, 18B and 19A, 19B coincide with each other or to positions where the projections or stoppers collide to obtain a click feeling. Further, the direction in which the conditioned air (warm air) is blown by the upper and lower louvers 13 can be the direction of collision with the center pillar 17.

  For this reason, everyone makes the warm air from the side face outlets 8 and 9 collide with the center pillar 17 only by a simple movable operation of the left and right louvers 12 and the upper and lower louvers 13, and the warm air is collided with the flow pattern described above in the vehicle interior. It can be distributed throughout the entire area. Accordingly, it is possible to promote mixing and diffusion of warm air by forced convection and to obtain a comfortable heating feeling.

  Further, instead of the louver position control means such as the marks 18A, 18B, 19A, 19B, the left and right louvers 12 and the upper and lower louvers 13 are connected to the center pillar 17 via the air conditioning controller by manual operation of operation buttons or the like or detection of the set outside air temperature. By providing a louver movable mechanism such as an actuator or a link mechanism that moves to a position where air conditioned air is blown in the direction of collision with the louver, a louver can be operated via an air conditioning controller by manual operation of an operation button or the like or detection of a set outside air temperature. By operating the movable mechanism, the left and right louvers 12 and the upper and lower louvers 13 can be moved and fixed at positions where air conditioned air (warm air) is blown out in a direction in which the left and right louvers 13 and the upper louver 13 automatically collide with the center pillar 17.

  For this reason, by moving and fixing the left and right louvers 12 and the upper and lower louvers 13 to a position where the hot air is blown in the direction of colliding with the center pillar 17, the operability and operation accuracy of the left and right louvers 12 and the upper and lower louvers 13 are improved. Therefore, a more comfortable feeling of heating can be obtained in the entire vehicle interior 1.

[Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to FIGS.
This embodiment differs from the first embodiment described above in that the collision surface of the conditioned air in the center pillar 17 is an arc surface. Since other points are the same as those in the first embodiment, description thereof will be omitted.
In the present embodiment, the front side surface of the center pillar 17 to which the conditioned air (warm air) blown out from the side face air outlets 8 and 9 collides is shown in FIG. , C, D, as shown in FIGS. 6 (B), (C), (D), a concave arcuate surface 17A that turns the flow of conditioned air toward the center in the width direction in the passenger compartment 1 is formed. Yes.

As described above, the front side surface on which the conditioned air (warm air) of the center pillar 17 collides is the concave arc surface 17A that turns the flow of warm air toward the center in the width direction of the vehicle interior 1. Thus, the conditioned air (warm air) collided with the center pillar 17 can be smoothly turned toward the center in the width direction of the passenger compartment 1 by the concave arcuate surface 17A. And the diffusion of warm air can be suppressed.
Therefore, it is possible to improve the reachability of the warm air to the downstream side (rear seats 5 and 6 side) and reduce the required air volume. Further, since the flow of warm air along the side window 16 can be reliably turned to the center in the width direction of the passenger compartment 1, the warm air is directly applied to the passengers on the rear seats 5 and 6 side, particularly near the face. It is possible to prevent the wind from hitting.

  It should be noted that the front side surface of the center pillar 17 is not a simple concave arcuate surface 17A as shown in FIG. 6, but as shown in FIG. As shown in (B), (C), (D), the slope is gradually changed from the straight surface to the concave arc surface from the lower side to the upper side, and further inclined toward the front end side protruding into the vehicle interior 1. It is good also as the concave circular arc surface 17B which becomes large gradually.

  In this way, the front side surface of the center pillar 17 is a concave circular arc surface 17B whose sectional shape gradually changes in the height direction, thereby changing the warm air flow near the face of the rear seat occupant and near the shoulder / elbow. It becomes possible to make it. As a result, the feeling of heating of the whole body can be improved by flowing a part of the warm air near the shoulder / elbow while preventing the rear seat occupant from burning the face.
