Description

  The present invention relates to an air guide structure for a passenger car, and more specifically, temperature-controlled air blown from a first air outlet provided on an upper surface of an instrument panel toward a front portion of a roof portion in a passenger compartment, and the instrument The present invention relates to an air guide structure for a passenger car in which temperature-controlled air blown from a second air outlet provided on the upper surface of the panel toward a front window is guided toward a rear space or a rear window of the passenger compartment.

  In passenger cars equipped with three rows of seats, such as 1-box type minivans and wagons, consisting of front row, middle row, and rear row, the cabin space of the passenger compartment is considerably larger than that of sedan type passenger cars and small vehicles, Accordingly, it is necessary to stably and efficiently air-condition the entire passenger compartment. Therefore, in the minivan type passenger car, an air conditioner unit that is mounted inside the instrument panel and air-conditions the front space of the passenger compartment (mainly the installation portion of the front row seat), and the rear space (mainly the passenger compartment) It is equipped with another air conditioning unit that air-conditions the middle row seat and the rear row seat). On the other hand, in the wagon type passenger car, since the passenger compartment has a smaller interior space than the minivan type, one air conditioner unit mounted inside the instrument panel is used for both the front space and the rear space of the passenger compartment. Air conditioning is to be performed.

  For example, FIG. 10 is an explanatory view schematically illustrating the passenger compartment in the wagon type passenger car described above, and FIG. 11 is a schematic perspective view of an instrument panel indicated by reference numeral 10 in FIG. The instrument panel 10 is installed on the front side of the passenger compartment with the air conditioner unit AC stored therein, and has a plurality (four in the figure) of front air outlets 12 opened on the front side thereof, and an upper front side (front row seat). And a defrost air outlet 16 that is elongated in the width direction on the upper rear side (front window FW side). Among these, the front air outlet 12 is used for blowing out the temperature-controlled air for air conditioning the front space 22 in the passenger compartment 20, and directly blows the temperature-controlled air toward the front space 22. It is like that. Further, the rear air outlet 14 is used for blowing out the temperature-controlled air for air conditioning the rear space 24 in the passenger compartment 20, and by blowing out the temperature-controlled air toward the upper part of the front space 22, The temperature-controlled air is moved rearward along the inner side of the interior roof panel 29 disposed in the roof portion 26 so as to arrive at the rear space 24. Further, the defrost air outlet 16 is used for blowing out temperature-controlled air for defrosting the front window FW located in front of the passenger compartment 20, and the temperature is adjusted toward the front window FW. The air is blown out directly.

The so-called “air conditioning mode” in which the temperature-controlled air is blown out from the front air outlet 12 and / or the rear air outlet 14, the so-called “air-conditioning mode” in which the temperature-controlled air is blown out from the defrost air outlet 16. The “defrost mode” and various blowout modes for blowing the temperature-controlled air from an air blowout port (not shown) are switch operations in the air conditioning operation panel 18 disposed on the front surface of the instrument panel 10 illustrated in FIG. Is selected and set. The air guide structure related to air conditioning in the passenger compartment described above is disclosed in, for example, Patent Document 1.
JP 09-30241 A

  By the way, in the conventional air guide structure for the passenger compartment illustrated in FIG. 10, when the air conditioning mode for air conditioning of the rear space 24 is set, the rear air outlet 14 is located above the front space 22, that is, the roof portion 26. In many cases, the temperature-controlled air blown toward the front edge side of the front side of the rear side of the rear space 24 is gradually reduced and diffused while moving to the rear side along the interior roof panel 29 and does not surely reach the rear space 24. There is a problem that it is difficult to effectively and efficiently air-condition the space 24. In addition, when the driver and / or passenger seated in the front row seat are tall, the temperature-controlled air blown out from the rear air outlet 14 may be blown directly onto the head or face. Inconvenience that may cause discomfort may occur.

  On the other hand, in most passenger cars including the wagon type illustrated in FIG. 10, heat generated when the rear window RW located behind the passenger compartment 20 is de-fogged by energizing the hot wire heater disposed in the rear window RW. It was common to use. However, the heat wire heater consumes a large amount of power, and in some cases forgets to turn off the switch and may be left in an energized state, which causes a problem of increasing the load on the battery. That is, in the prior art, there is no technical idea that the rear window RW located behind the passenger compartment 20 is also defrosted by using the temperature-controlled air provided for the defrosting of the front window FW. When the defrost mode is set at 18, the temperature-controlled air blown out from the defrost air outlet 16 toward the front window FW is convected as it is above the front space 22 after being defrosted by the front window FW. It was like that.

  Therefore, in the present invention, an air guide duct is provided in the roof portion of the passenger compartment so that the temperature-controlled air blown from the air outlet provided in the instrument panel is guided to the rear space or rear window side of the passenger compartment. It is an object of the present invention to provide an air guide structure for a passenger car that is configured to effectively and efficiently air-condition the entire passenger compartment and / or to efficiently remove fogging of the rear window.

  The air guide structure according to the present embodiment includes temperature-controlled air blown from the rear air outlet 14 provided on the upper surface of the instrument panel 10 toward the front portion of the roof portion 26 in the passenger compartment 20, and the instrument panel. The temperature-controlled air blown from the defrost air outlet 16 provided on the upper surface of the vehicle 10 toward the front window FW is selectively directed toward the rear space 24 of the passenger compartment 20 or the rear window RW located behind the passenger compartment 20. It is designed to guide you. For example, as will be described later, temperature-controlled air for air conditioning of the rear space 24 blown out from the rear air outlet 14 is actively guided to the rear space 24 of the passenger compartment 20 and used for air conditioning of the rear space 24. It is possible to positively guide the temperature-controlled air for removing the fog of the front window FW blown out from the defrost air outlet 16 to the rear window RW and use it for fogging the rear window RW. Specifically, the air guide duct 30 disposed on the roof portion 26 so as to extend in the front-rear direction, the air blower 40 disposed at a required position of the air guide duct 30, and the air guide duct. The shutter device 50 is basically composed of 30 required positions.

  The air guide duct 30 is disposed on the roof portion 26 so as to extend in the front-rear direction thereof, and has an air suction port 32 that opens on the upper edge side (front edge side of the roof portion 26) of the front window FW. The first air delivery port 34 opened above the rear space 24 and the second air delivery port 36 opened on the upper edge side of the rear window RW. The air guide duct 30 is made of a synthetic resin material such as polyethylene (PE), polypropylene (PP) or urethane, and is assembled from the passenger compartment side with respect to the exterior roof panel 28 which is a vehicle body component and the exterior roof panel 28. It is formed in a thin and flat shape that is disposed using a roof space 27 defined between the interior roof panel 29 and the interior roof panel 29, and the interior height of the passenger compartment 20 is considered not to decrease. . In this embodiment, as illustrated in FIG. 6, a total of two air guide ducts 30, 30 are arranged in parallel on both sides of the roof portion 26 in the vehicle width direction. It does not interfere with the installation or the opening of the sunroof.

  As illustrated in FIG. 6, the air suction port 32 in each of the air guide ducts 30 is formed in a widened shape on the front end side of the opening, and the upper edge side of the front window FW (the front edge side of the roof portion 26). ) And the air suction ports 32 and 32 of both air guide ducts 30 cover substantially the entire upper edge of the front window FW. Accordingly, the temperature-controlled air that has been blown from the rear air outlet 14 and diffused to the front edge of the roof portion 26, or is blown from the defrost air outlet 16 and diffused to the upper edge of the front window FW. The incoming conditioned air can be efficiently taken in from a wide range of areas. Each air suction port 32 is fitted with a bezel 60 attached from the outside of the interior roof panel 29 (FIG. 2).

  Each of the air guide ducts 30 is provided with two each of the first air delivery ports 34, and the first air delivery ports 34 established on the upstream side of the ducts are located above the middle row seats, The first air outlet 34 opened on the downstream side is located above the rear row seat. Each of the first air outlets 34 is fitted and fitted with an air outlet 62 having a wind direction adjusting plate 64 from the outside of the interior roof panel 29 as illustrated in FIGS. 3 and 4. The direction of blowing out the temperature-controlled air can be adjusted by the operation of the occupant's fingertips. Each of the air outlets 62 is provided with an opening / closing member 66 that can open and close the corresponding first air outlet 34, and allows the temperature-controlled air to be blown out from the first air outlet 34. It can be blocked. The opening / closing member 66 automatically opens and closes the corresponding first air outlet 34 in accordance with the temperature-controlled air blowing mode selected on the air conditioning operation panel 18. That is, the opening / closing member 66 opens the corresponding first air outlet 34 to allow the temperature-controlled air to be blown out in the temperature-controlled air blowing mode from the rear air outlet 14 (air-conditioning mode of the rear space 24). On the other hand (in the state shown in FIG. 4), in the temperature-controlled air blowing mode (defrost mode) from the defrost air outlet 16, the corresponding first air outlet 34 is closed to regulate the temperature-controlled air blowing. Control is performed as shown in FIG.

  Further, as illustrated in FIG. 6, the second air delivery port 36 is formed in a widened shape at the rear end side of the opening, and is opened horizontally at the upper end side of the rear window RW. The second air outlets 36, 36 cover substantially the entire area of the upper edge of the rear window RW. Therefore, the temperature-controlled air that has moved through each air guide duct 30 can be diffused and blown out to a wide area of the rear window RW. Each second air outlet 36 is fitted with a bezel 68 with fins attached from the outside of the interior roof panel 29.

  The air blower 40 is a fan, a blower or the like, for example, as illustrated in FIGS. 2 and 6, a blower blade body 42 located in the air guide duct 30 and a motor for rotating the blower blade body 42. And the like, and is configured to suck the conditioned air from the air suction port 32 into the duct, and the conditioned air sucked into the duct into the first air delivery port 34 or the second air. This is for positive transfer to the delivery port 36. The drive means 44 is controlled to operate in conjunction with a switch operation on the air conditioning operation panel 18, and is ON-controlled only when, for example, the air conditioning mode or the defrost mode is selected and set by a switch operation, Even if a mode other than this is selected and set, it is set so that ON control is not performed.

  As illustrated in FIGS. 4 and 6, the shutter device 50 includes, in each of the air guide ducts 30, the first air outlet 34 and the second air outlet 36 that are located on the downstream side of the duct. Specifically, it is disposed immediately downstream of the first air outlet 34. The shutter device 50 includes a damper-type shutter plate 52 disposed in the corresponding air guide duct 30 and an operating means 54 such as a motor or an actuator linked to the shutter plate 52. The shutter plate 52 can be displaced to a first position where the inside of the duct between the first air outlet 34 and the second air outlet 36 is not in communication and a second position where it is in communication. That is, when the shutter plate 52 is displaced to the first position, the temperature-controlled air from the rear air outlet 14 and / or the temperature-controlled air from the defrost air outlet 16 arriving at the air suction port 32 is When air is blown from the first air outlet 34 toward the rear space 24 to air-condition the rear space 24 or the shutter plate 52 is displaced to the second position, the air suction port 32 is reached. The conditioned air from the rear air outlet 14 and / or the conditioned air from the defrost air outlet 16 are blown out from the second air outlet 36 toward the rear window RW to defoam the rear window RW. You can do so. However, in this embodiment, in the temperature-controlled air blowing mode from the rear air outlet 14, the shutter plate 52 is displaced to the first position where the air outlets 34 and 36 are not in communication (see FIG. 5 and FIG. 6), in the temperature-controlled air blowing mode from the defrost air outlet 16, the shutter plate 52 is set to be displaced to a second position where the air outlets 34 and 36 are in communication with each other. (FIGS. 7 and 8).

  Therefore, in the temperature-controlled air blowing mode (air-conditioning mode) from the rear air outlet 14, the movement of the temperature-controlled air toward the second air outlet 36 is restricted by the shutter plate 52, and Since the opening / closing member 66 of the first air delivery port 34 opens the first air delivery port 34, the temperature-controlled air transferred by the blower blade body 42 is transmitted from each first air delivery port 34 to the passenger compartment 20. It controls to blow out to the rear space 24. Further, in the temperature-controlled air blowing mode (defrost mode) from the defrost air outlet 16, the movement of the temperature-controlled air toward the second air outlet 36 is allowed, and the first air Since the opening / closing member 66 of the outlet 34 closes the first air delivery port 34, the temperature-controlled air transferred by the blower blade body 42 is controlled to blow out from the second air delivery port 36 to the rear window RW. Is done.

  Next, the operation of the air guiding structure for the passenger compartment according to the present embodiment configured as described above will be described.

(In air conditioning mode)
When the air conditioning mode of the front space 22 and the rear space 24 in the passenger compartment 20 is selected and set by a switch operation on the air conditioning operation panel 18 installed in the instrument panel 10, the damper inside the unit is appropriately set in the air conditioner unit AC. The posture is changed, and the temperature-controlled air can be blown out from the front air outlet 12 and the rear air outlet 14. On the other hand, in the shutter device 50, the shutter plate 52 is controlled to be displaced to the first position by the operating means 54, and the first air delivery port 34 and the second air delivery port 36 are not in communication with each other. It becomes. In each of the first air outlets 34, the opening / closing member 66 of the air outlet 62 opens the corresponding first air outlet 34, and the temperature-controlled air can be blown out.

  Under this condition, when the operation switch is turned on in the air conditioning operation panel 18, temperature-controlled air is blown out simultaneously from the front air outlet 12 and the rear air outlet 14, and the blower 40 is turned on. Thus, the blower blade body 42 starts to rotate. Thereby, the temperature-controlled air blown out from the front air outlet 12 is directly blown out to the front space 22 of the passenger compartment 20, and the air conditioning of the front space 22 is performed stably and efficiently. It becomes like this. On the other hand, the temperature-controlled air blown upward from the rear air outlet 14 is partly above the front space 22 along the interior roof panel 29 of the roof portion 26 as illustrated in FIGS. Is moved to the rear side and appropriately arrives at the rear space 24. However, most of the temperature-controlled air blown out from the rear air outlet 14 is sucked into the duct from the air suction port 32 of the air guide duct 30 when it reaches the front edge of the roof portion 26, and the air guide duct. The inside 30 is transferred to the first air outlet 34 side (rear side). Thereby, about half of the temperature-controlled air sucked into the air guide duct 30 is blown upward from the first air outlet 34 located above the middle row seat to the rear space 24. Further, the remaining temperature-controlled air is blown out from the first air outlet 34 located above the rear row seats to the upper side of the rear space 24, and the rear space 24 is effectively and efficiently air-conditioned. Will come to be.

(In defrost mode)
On the other hand, when the defrost mode is selected and set by the switch operation on the air conditioning operation panel 18, the damper inside the unit is appropriately displaced in the air conditioner unit AC, and the temperature-controlled air can be blown from the defrost air outlet 16 Set to state. Also, in the shutter device 50, the shutter plate 52 is controlled to be displaced to the second position by the actuating means 54, and the communication between the first air outlet 34 and the second air outlet 36 is established. Become. In each of the first air outlets 34, the opening / closing member 66 of the air outlet 62 closes the corresponding first air outlet 34, and the temperature-controlled air cannot be blown out.

  Under this condition, when the operation switch is turned on in the air conditioning operation panel 18, temperature-controlled air is blown out from the defrost air outlet 16, and the blower 40 is turned on to control the blower blade body 42. Starts to rotate. Thereby, the temperature-controlled air blown from the defrost air outlet 16 is blown to the front window FW and rises along the inner surface of the front window FW, as illustrated in FIGS. 7 and 8. In this process, the front window is defrosted. Then, the temperature-controlled air that has arrived at the upper edge of the front window FW is sucked into the duct from the air suction port 32 of the air guide duct 30, and the inside of the air guide duct 30 is on the side of the second air delivery port 36. It is transferred to (rear side). Thereby, all the temperature-controlled air sucked into the air guide duct 30 passes through the first air outlets 34 and is widely blown out from the second air outlet 36 to the upper edge of the rear window RW. Thus, the rear window RW is efficiently defoamed in the process of descending along the inner surface of the rear window RW.

  Thus, according to the air guide structure for the passenger compartment according to the present embodiment, most of the temperature-controlled air blown from the rear air outlet 14 of the instrument panel 10 is provided in the roof portion 26. After being transferred to the rear side of the passenger compartment 20 using the duct 30, the air is blown out to the rear space 24 of the passenger compartment 20 through the first air delivery port 34, and the rear space 24 is effectively and Efficient air conditioning can be achieved. Further, the temperature-controlled air blown from the defrost air outlet 16 of the instrument panel 10 is blown to the front window FW to be used for removing the fog of the front window FW, and then the air disposed on the roof portion 26 is used. After being transferred to the rear side of the passenger compartment 20 by the guide duct 30, it is blown to the rear window RW through the second air outlet 36, and the rear window RW can be efficiently defrosted. That is, the rear window RW is defoamed with temperature-controlled air, which has been conventionally used only for defoaming the front window FW, so a hot wire heater with high power consumption is used for defoaming the rear window RW. It is possible to reduce the load on the battery.

  In the embodiment, the opening / closing member 66 disposed at the first air delivery port 34 is automatically opened and closed according to the temperature-controlled air blowing mode selected and set on the air conditioning operation panel 18. Although the form has been illustrated, the opening / closing member 66 may be a manual opening / closing type by an occupant's fingertip operation.

  Moreover, in the said Example, although the case where the two air guide ducts 30 and 30 were arrange | positioned in parallel and independently on the both right and left sides of the vehicle width direction in the roof part 26 was illustrated, for example, it illustrates in FIG. In addition, a communication duct 70 extending in the vehicle width direction of the roof portion 26 may be provided at a required position of the roof portion 26, and the two air guide ducts 30 may be connected to each other by the communication duct 70. In such a form, it is possible to further open an air outlet 72 in the communication duct 70, and it becomes possible to blow out temperature-controlled air from the substantially central portion of the roof portion 26 toward the rear space 24. Effective and efficient air conditioning of the rear space 24 can be performed.

  In the above-described embodiment, the case where two air guide ducts 30 are provided on both the left and right sides of the roof portion 26 in the vehicle width direction is illustrated, but one is provided on either the left side or the right side of the roof portion 26. An air guide duct 30 may be provided. Furthermore, when there is no influence on the installation of the room lamp or the opening of the sunroof, one air guide duct 30 may be disposed at the left and right center of the roof portion 26 in the vehicle width direction. Further, although not shown, three or more air guide ducts may be disposed on the roof portion 26.

  The air guide structure for a passenger car according to the present invention directs temperature-controlled air blown from the first air outlet provided on the upper surface of the instrument panel toward the front portion of the roof portion in the passenger compartment toward the rear space of the passenger compartment. Air guidance for passenger cars that guides or regulates the temperature-controlled air blown from the second air outlet provided on the upper surface of the instrument panel toward the front window toward the rear window located behind the passenger compartment In particular, it can be suitably used for a passenger car having a large passenger compartment volume such as a minivan type or a wagon type.
