Description

  The present invention relates to an air blowing device that blows air into a passenger compartment.

  Conventionally, as this type of air blowing device, for example, there is one described in Patent Document 1. The air blowing device described in Patent Document 1 has a meter vent outlet and blows out air from the front of the driver. And the meter vent blower outlet is provided in the position of the meter hood which is not reflected in a windshield.

JP 2005-199764 A

  The air blowing device of Patent Document 1 blows air from the periphery of the meter to the rear of the vehicle, but can blow out the air only under certain conditions in wind speed, wind direction, and temperature. Therefore, depending on the environmental conditions and the passenger's preference, the air blown out from the air blowing device may give the driver unpleasant feeling. In order to remove the unpleasant feeling, the blowing of the air is generally not performed. Methods such as stopping or lowering the blowing air volume were taken.

  For example, the passenger's hand is cold immediately after boarding in winter, and it is required to quickly warm the hand. However, with the air blowing device of Patent Document 1, it is difficult to intensively reach the hand with the air blowing device. Further, if warm air is blown out from the air blowing device of Patent Document 1, a part of the warm air may flow to the driver's hand, but most of the blown warm air is a steering wheel. Because it blows to the center, it is sprayed on the driver's face. As a result, it is assumed that the driver's face is steamed and the eyes are dry, giving the driver discomfort. That is, in the air blowing device of Patent Document 1, there are limited cases where the blowing air from the air blowing device is required from the viewpoint of improving the driver's comfort. As a result of detailed studies by the inventors, the above has been found.

  In view of the above points, the present invention increases the chances of blowing out the wind required from the viewpoint of improving the driver's comfort when blowing air to the driver from the front of the driver. An object of the present invention is to provide an air blowing device that can perform the above-described operation.

In order to achieve the above object, an air blowing device according to the invention described in claim 1 comprises:
An air blowing device that blows air into the passenger compartment,
A portion (762) excluding the meter (761) of the meter panel (76) disposed in front of the vehicle in the driver's seat (74) in the passenger compartment and on the upper side of the meter panel so as to extend in the vehicle width direction (DR3). A blower outlet (121) that opens to blow air from the blower (90) to the rear of the vehicle is formed in a meter peripheral region that is provided and is provided with a meter hood (78) that protrudes rearward of the meter panel. The blowing part (12),
A distribution changing unit (14) that changes a blown air distribution that is a distribution of at least one of a wind speed, a temperature, and a wind direction of the blown air blown out from the blower outlet;

  As described above, the blowout portion is formed with a blowout opening that opens to blow the air from the blower to the rear of the vehicle in the meter peripheral region. The distribution changing unit changes a blown air distribution that is at least one of a wind speed, a temperature, and a wind direction of the blown air blown from the blower outlet. Therefore, compared with the case where the blowing air distribution does not change, it becomes easier to improve the driver's comfort by changing the blowing air distribution. Therefore, when the air blowing device blows air from the front of the driver to the driver, it is possible to increase the chances of blowing the wind required from the viewpoint of improving the driver's comfort to the driver.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. In the following embodiments, the same or equivalent parts are denoted by the same reference numerals in the drawings.

(First embodiment)
The air blowing device 10 of the present embodiment is used as a part of an air outlet and a duct of an air conditioning unit 90 installed in front of a vehicle in a vehicle interior.

  As shown in FIGS. 1 and 2, the air blowing device 10 is provided on the instrument panel 70. Similar to a general vehicle, the instrument panel 70 is disposed in front of the vehicle in the passenger compartment. In addition, a driver's seat 74 on which a driver 72 as one of the passengers sits and a passenger seat on which a passenger 73 who is a passenger different from the driver 72 sits on the instrument panel 70 in the passenger compartment. On the other hand, it is arranged behind the vehicle. The driver's seat 74 is disposed on the right side toward the front of the vehicle, and the passenger seat is disposed on the left side toward the front of the vehicle. In short, the driver seat 74 is arranged on the right side in the vehicle width direction DR3 with respect to the passenger seat.

  In addition, each arrow DR1, DR2, DR3 of FIG. 1 and FIG. 2 shows the direction of the vehicle 88 in which the air blowing apparatus 10 is mounted. That is, the arrow DR1 in FIG. 1 indicates the vehicle longitudinal direction DR1, the arrow DR2 indicates the vehicle vertical direction DR2 (in other words, the vehicle vertical direction DR2), and the arrow DR3 in FIG. 2 indicates the vehicle lateral direction DR3 (in other words, the vehicle width). Direction DR3). These three directions DR1, DR2, and DR3 are directions that intersect each other, and strictly speaking, are directions that are orthogonal to each other.

  As shown in FIGS. 1 and 3, the instrument panel 70 includes a meter panel 76 including a meter 761 such as a speedometer or a tachometer, and a meter hood 78 that covers the upper side of the meter panel 76.

  As shown in FIGS. 3 and 4, the meter panel 76 has a meter peripheral portion 762 that constitutes the periphery of the meter 761 in addition to the two meters 761. The meter panel 76 is arranged so that the two meters 761 and the meter peripheral portion 762 can be seen when the meter panel 76 is viewed from the driver's seat 74 side. 3 and 4 are views in which the meter panel 76 and the meter hood 78 are viewed from the driver 72 in the driving posture, but the steering wheel 80 is omitted in FIG. .

  The meter hood 78 is provided to extend in the vehicle width direction DR3 above the meter panel 76, that is, above the meter panel 76. The meter hood 78 projects rearward from the meter panel 76 as shown in FIGS. 1 and 3. Since the meter hood 78 protrudes toward the rear of the vehicle, the meter hood 78 has a hood rear end 781 positioned most rearward of the meter hood 78. The meter hood 78 has a hood lower surface 782, and the hood lower surface 782 extends obliquely downward from the hood rear end 781 toward the front of the vehicle. The hood lower surface 782 may be a smooth curved surface or may have a step.

  As shown in FIG. 1, the meter panel 76 and the meter hood 78 are disposed in the vehicle interior in front of the driver seat 74, in other words, in front of the vehicle with respect to the driver seat 74. A steering column 82 protrudes from the lower part of the instrument panel 70 relative to the meter panel 76 toward the driver's seat 74, and a steering wheel 80 is provided at the tip of the steering column 82.

  The steering wheel 80 is disposed between the meter panel 76 and the driver seat 74 in the vehicle longitudinal direction DR1. That is, the steering wheel 80 is disposed in front of the driver seat 74 at a position closer to the driver seat 74 than the meter panel 76 and the meter hood 78.

  Similar to a general vehicle steering wheel, the steering wheel 80 has a ring shape formed around the central axis of the steering column 82 that faces obliquely upward toward the rear of the vehicle. In this embodiment, the center position of the driver's seat 74, the center position of the meter panel 76, and the center position of the meter hood 78 coincide with the center position CLs (see FIG. 4) of the steering wheel 80 in the vehicle width direction DR3. ing.

  As shown in FIG. 1, the air blowing device 10 is a device that blows air blown from the air conditioning unit 90 into the vehicle interior. In other words, the air conditioning unit 90 functions as a blower that sends air to the air blowing device 10.

  The air conditioning unit 90 is a well-known device that is arranged in the instrument panel 70 and blows out the conditioned air whose temperature is adjusted toward the vehicle interior. For example, the air conditioning unit 90 is the same as the indoor air conditioning unit disclosed in Japanese Patent Application Laid-Open No. 2013-082398.

  As shown in FIG. 5, the air blowing device 10 includes a blowing unit 12 that blows out the blown air from the air conditioning unit 90, a distribution changing device 14, and a duct unit 18.

  The outlet 12 is provided integrally with the meter hood 78. The blowout portion 12 is formed with an air outlet 121 that is opened so as to blow out the air blown from the air conditioning unit 90 to the rear of the vehicle. Specifically, the air outlet 121 opens at the hood lower surface 782 of the meter hood 78. And the blower outlet 121 is formed in the vehicle rear with respect to the upper end of the transparent meter window 84 arrange | positioned at the vehicle rear of the meter panel 76. FIG.

  More specifically, the air outlet 121 opens toward the rear of the vehicle, and blows air from the air conditioning unit 90 in the opening direction. That is, the blower outlet 121 blows out at least a part of the blown air from the air conditioning unit 90 to the rear of the vehicle through the inside of the steering wheel 80 as indicated by an arrow FL1. The arrow FL1 represents the main flow of the air blown from the blower outlet 121 (that is, the blown air from the blower outlet 121).

  In the present embodiment, since the state of the air blown from the outlet 121 changes according to the operation of the distribution changing device 14 as described later, most of the air blown from the outlet 121 depends on the operation of the distribution changing device 14. May not pass through the inside of the steering wheel 80.

  The meter window 84 described above is, for example, a transparent acrylic plate, and is a so-called non-reflective plate that suppresses reflection to the driver 72 (see FIG. 1). Further, the meter window 84 is warped such that the lower end of the meter window 84 is located at the rear of the vehicle. Due to the downward warping of the meter window 84, the mountability of the blowing portion 12 is improved.

  Specifically, as shown in FIGS. 1 and 3, the air outlet 121 opens toward the rear of the vehicle at the hood lower surface 782. Further, the air outlet 121 is formed symmetrically in the vehicle width direction DR3 with reference to the center position CLs of the steering wheel 80. For example, the air outlet 121 is opened so as to be thin in the vehicle vertical direction DR2 and to expand in the vehicle width direction DR3. Thereby, the blowing part 12 can blow toward the driver | operator 72 the airflow symmetrical to the vehicle width direction DR3 centering on the center position CLs of the steering wheel 80. FIG.

  Further, as shown in FIG. 5, a blowing air passage 123 is formed in the blowing portion 12. The outlet air passage 123 extends from the outlet 121 to the front of the vehicle. In other words, the outlet air passage 123 extends from the outlet 121 to the upstream side of the air flow. Then, the blown air from the air conditioning unit 90 flows into the blown air passage 123, and the blown air passage 123 flows the blown air into the blowout port 121.

  That is, the blowout part 12 has a blower outlet peripheral part 122 that forms the peripheral edge of the blower outlet 121, and a passage inner wall surface 124 that surrounds the blown air passage 123. The inner wall surface 124 of the passage extends from the outlet peripheral edge 122 to the front of the vehicle.

  Further, the passage inner wall surface 124 is inclined so that the front side of the passage inner wall surface 124 in the vehicle longitudinal direction DR1 is lowered with respect to the rear side. Specifically, the passage inner wall surface 124 is formed such that an upper portion 124a of the passage inner wall surface 124 extends obliquely downward from the upper portion 122a of the outlet peripheral portion 122 toward the front of the vehicle. .

  As shown in FIG. 5, the duct portion 18 is provided on the air flow upstream side of the blowing portion 12 and is connected to the blowing portion 12. And the duct part 18 flows the blowing air from the air conditioning unit 90 to the blowing part 12. FIG. That is, a duct passage 181 that is an air passage through which air blown from the air conditioning unit 90 flows is formed inside the duct portion 18.

  And the duct channel | path 181 is provided in the air flow upstream rather than the blowing air channel | path 123 of the blowing part 12. FIG. As a result, the blown air from the air conditioning unit 90 flows into the duct passage 181 as indicated by the arrow FLin, and the duct portion 18 causes the blown air that has flowed into the duct passage 181 to flow to the blowing air passage 123.

  The duct portion 18 is disposed so as to flow air from the bottom to the top, and is provided in front of the vehicle with respect to the meter panel 76. In other words, the duct portion 18 is provided so as to overlap the meter panel 76 in front of the vehicle.

  The distribution changing device 14 of the air blowing device 10 functions as a distribution changing unit that changes the distribution of the state of the blowing air blown from the blower outlet 121. In the present embodiment, the distribution of the state of the blown air is, for example, the distribution of the wind speed and direction of the blown air, and thus the distribution changing device 14 may be called a distributed wind direction adjusting device.

  As shown in FIGS. 5 and 6, the distribution changing device 14 includes a right door 15 as a first rotating door and a left door 16 as a second rotating door. Since both of these two rotating doors 15 and 16 are provided in the blowout air passage 123, they are located on the upstream side of the air flow with respect to the blowout port 121, that is, in front of the vehicle.

  The distribution changing device 14 is operated by electrical control of an electronic control device (not shown). For example, the two turning doors 15 and 16 of the distribution changing device 14 are connected to an electric actuator, and the respective turning doors 15 and 16 are turned by electrical control.

  The right door 15 is arranged on the right side which is one side with respect to the left door 16 in the vehicle width direction DR3. The right door 15 has a right door center shaft 151 extending substantially in the vehicle vertical direction DR2 and a flat right door plate portion 152 connected to the right door center shaft 151.

  The right door plate portion 152 is formed so as to extend from the right door central shaft 151 to one side in the radial direction of the right door central shaft 151. Then, the right door plate portion 152 rotates integrally with the right door center shaft 151. In short, the right door 15 rotates around the center axis CL1 of the right door center axis 151, that is, around the right door axis CL1.

  The left door 16 is the same as the right door 15 described above. That is, the left door 16 has a left door center shaft 161 corresponding to the right door center shaft 151 and a left door plate portion 162 corresponding to the right door plate portion 152. The left door 16 rotates about the center axis CL2 of the left door center axis 161, that is, around the left door axis CL2.

  With such a configuration, the distribution changing device 14 turns the opening area (in other words, the open area) of the blowout air passage 123 corresponding to the opening area of the blowout outlet 121 to rotate the right door 15 and the left door 16 respectively. Increase or decrease depending on the position. Then, the distribution changing device 14 adjusts the distribution of the wind speed and direction of the blown air described above according to the respective rotational positions of the right door 15 and the left door 16.

  Moreover, as shown in FIGS. 6-8, the two door center shafts 151 and 161 of the distribution change apparatus 14 are arrange | positioned along with the mutual space | interval in the vehicle width direction DR3 within the blowing air path 123. As shown in FIG. Therefore, the blown air passage 123 is divided by the two door central shafts 151 and 161, and includes a plurality of divided passages 123a, 123b, and 123c arranged side by side in the vehicle width direction DR3.

  The plurality of division passages 123a, 123b, and 123c are three division passages 123a, 123b, and 123c, which are a central division passage 123a, one side division passage 123b, and the other side division passage 123c. And the air which each passed through the three division | segmentation channel | paths 123a, 123b, 123c blows off from the blower outlet 121. FIG. The three divided passages 123a, 123b, and 123c are formed so as to be symmetrical in the vehicle width direction DR3 as a whole.

  6 to 8, the blown air blown out through the central divided passage 123a is represented by arrows FL1a, FL1b, and FL1c. The blown air blown out through the one-side divided passage 123b is represented by arrows FL2a, FL2b, and FL2c. The blown air blown out through the other side divided passage 123c is represented by arrows FL3a, FL3b, FL3c. Moreover, each arrow FL1a-FL3c represents the air flow with a larger air volume as the arrow is thicker. Moreover, since the two turning doors 15 and 16 of the distribution changing device 14 turn in conjunction with each other so as to be symmetrically arranged in the vehicle width direction DR3, the arrows FL1a to FL3c in FIGS. As shown, the air blown from the air outlet 121 has a symmetrical air flow in the vehicle width direction DR3.

  In the vehicle width direction DR3, the right door central shaft 151 is disposed between the one side divided passage 123b and the central divided passage 123a, and the left door central shaft 161 is disposed between the other side divided passage 123c and the central divided passage 123a. Is arranged.

  Therefore, the one-side divided passage 123b is arranged on the right side that is one side in the vehicle width direction DR3 with respect to the central divided passage 123a as one divided passage. With this arrangement, for example, the blown air blown through the one-side divided passage 123b as shown by the arrow FL2b in FIG. 7 is compared with the blown air blown through the central divided passage 123a as shown by the arrow FL1b. The air is blown out toward one side (that is, the right side) of the direction DR3. In other words, the blown air blown out through the one-side divided passage 123b is blown out toward the one side in the vehicle width direction DR3 with respect to the center position CLs of the steering wheel 80.

  Further, the other-side divided passage 123c is disposed on the left side that is the other side in the vehicle width direction DR3 with respect to the central divided passage 123a. With this arrangement, for example, the blown air blown through the other side divided passage 123c as shown by the arrow FL3b in FIG. 7 is compared with the blown air blown through the central divided passage 123a as shown by the arrow FL1b. It blows off toward the other side (namely, left side) of the direction DR3. In other words, the blown air blown out through the other-side divided passage 123c is blown out toward the other side in the vehicle width direction DR3 with respect to the center position CLs of the steering wheel 80.

  The distribution changing device 14 opens and closes the divided passages 123a, 123b, and 123c of the blown air passage 123 thus divided. Specifically, the distribution changing device 14 is switched to each of the first state DP1 shown in FIG. 6, the second state DP2 shown in FIG. 8, and the third state DP3 shown in FIG. Each of the pivot doors 15 and 16 can be continuously pivoted between a first position that is a pivot position in the first state DP1 and a second position that is a pivot position in the second state DP2. It is like that.

  Specifically, in the first state DP1 of the distribution changing device 14, as shown in FIG. 6, the central divided passage 123a is fully opened by the right door 15 and the left door 16. On the other hand, the one-side divided passage 123 b is fully closed by the right door 15, and the other-side divided passage 123 c is fully closed by the left door 16. As a result, the air blown from the air conditioning unit 90 is slightly blown into the vehicle compartment through the one side divided passage 123b and the other side divided passage 123c, but most of the blown air passes through the central divided passage 123a. And blown out into the passenger compartment.

  The fully open state of the passage is a state in which the opening degree of the passage is maximized in the change range of the opening degree. The fully closed state of the passage is a state in which the opening degree of the passage is minimized within the change range of the opening degree. The minimum opening of the passage may be 0% (that is, complete blockage), but the minimum opening is larger than 0% in each of the divided passages 123a, 123b, and 123c of the present embodiment. Even in the fully closed state, the passage slightly allows the passage of air.

  Further, in the second state DP2 of the distribution changing device 14, as shown in FIG. 8, the central dividing passage 123a is fully closed by the right door 15 and the left door 16. On the other hand, the one side divided passage 123 b is fully opened by the right door 15, and the other side divided passage 123 c is fully opened by the left door 16. As a result, the air blown from the air conditioning unit 90 is slightly blown into the passenger compartment through the central divided passage 123a, but most of the blown air passes through the one side divided passage 123b and the other side divided passage 123c. It is blown out into the passenger compartment.

  Further, the third state DP3 of the distribution changing device 14 is an intermediate operating state between the first state DP1 and the second state DP2, as shown in FIG. That is, in the third state DP3 of the distribution changing device 14, each of the pivot doors 15 and 16 is positioned at a third position that is an intermediate pivot position between the first position and the second position.

  Specifically, in the third state DP3 of the distribution changing device 14, all the divided passages 123a, 123b, 123c are fully opened by the right door 15 and the left door 16. Thereby, the blown air from the air conditioning unit 90 is blown out from the entire outlet 121 without being restricted by the right door 15 or the left door 16.

  Thus, the distribution changing device 14 includes the wind speed distribution of the air blown from the outlet 121 by switching the distribution changing device 14 to any one of the first, second, and third states DP1, DP2, and DP3. Change the air distribution. Since the plurality of divided passages 123a, 123b, 123c are arranged in the vehicle width direction DR3, the blown air distribution is a distribution that extends in the vehicle width direction DR3.

  More specifically, the wind speed distribution of the air blown from the air outlet 121 changes as the plurality of divided passages 123a, 123b, and 123c are opened and closed by the rotary doors 15 and 16, respectively. That is, the distribution changing device 14 changes the air velocity distribution of the blown air by changing the blockage range closed by the rotary doors 15 and 16 in the blown air passage 123 with the rotation of the rotary doors 15 and 16. Let

  For example, in the first state DP1 of the distribution changing device 14, as shown in FIG. 6, the blockage range of the blowing air passage 123 is not in the central division passage 123a, but is unevenly distributed in the one side division passage 123b and the other side division passage 123c. . In this case, the wind speed of the air flowing out from the central divided passage 123a is significantly higher than the wind speed of each air flowing out from the one side divided passage 123b and the other side divided passage 123c. In the first state DP1 of the distribution changing device 14, the wind speed of the air flowing out from the central divided passage 123a is higher than when the distribution changing device 14 is in the third state DP3.

  On the contrary, in the second state DP2 of the distribution changing device 14, as shown in FIG. 8, the blockage range of the blowout air passage 123 is not in the one-side divided passage 123b and the other-side divided passage 123c, but is unevenly distributed in the central divided passage 123a. To do. In this case, the wind speed of each of the air flowing out from the one-side divided passage 123b and the other-side divided passage 123c is significantly higher than the wind speed of the air flowing out from the central divided passage 123a. Then, in the second state DP2 of the distribution changing device 14, the wind speed of each air flowing out from the one side divided passage 123b and the other side divided passage 123c is compared with that in the case where the distribution changing device 14 is in the third state DP3. And get higher.

  Further, in the third state DP3 of the distribution changing device 14, as shown in FIG. 7, there is no closed range of the blowing air passage 123. In this case, the wind speeds of the air flowing out from the divided passages 123a, 123b, and 123c are approximately the same.

  Thus, changing the wind speed distribution of the blown air means that the wind speed of the blown air in the central portion of the air outlet 121 in the vehicle width direction DR3 and one side and the other of the central portion in the vehicle width direction DR3. The difference with the wind speed of the blown air on the side is changed.

  Here, as shown in FIGS. 6 to 8, the mutual ratio of the respective opening degrees of the plurality of divided passages 123 a, 123 b, 123 c is determined by the distribution changing device 14 in the first, second, and third states DP1, DP2, DP3. It changes depending on which one is. For example, the central opening ratio, which is the ratio of the opening of the central dividing passage 123a to the opening of the one-side and other-side dividing passages 123b, 123c, is compared with the third state DP3 in the first state DP1 of the distribution changing device 14. Is getting bigger. Conversely, the central opening ratio is smaller in the second state DP2 of the distribution changing device 14 than in the third state DP3. That is, it can be said that the distribution changing device 14 changes the blown air distribution in accordance with changing the mutual ratio of the respective opening degrees of the plurality of divided passages 123a, 123b, and 123c.

  In the air blowing device 10 configured as described above, the distribution changing device 14 is switched to the first state DP1 shown in FIG. 6 at the time of cool-down for quickly eliminating the heat, for example. Then, in the air blowing device 10, as shown by arrows FL1a, FL2a, and FL3a in FIG. 6, it is possible to blow out the cold air from the air conditioning unit 90 locally from the face of the driver 72 to the throat with a large air volume. It is.

  Further, at the time of steady operation in which the cooling of the vehicle interior is maintained and maintained, the distribution changing device 14 is switched to, for example, the third state DP3 shown in FIG. Then, in the air blowing device 10, as shown by arrows FL1b, FL2b, and FL3b in FIG. 7, the cold air from the air conditioning unit 90 can be blown out uniformly over the entire width of the air outlet 121 in the vehicle width direction DR3.

  Further, in the winter scene where it is desired to eliminate the cold, the distribution changing device 14 is switched to the second state DP2 shown in FIG. 8, for example. Then, the warm air from the air conditioning unit 90 can be blown out toward the grip portion of the steering wheel 80 as indicated by arrows FL1c, FL2c, and FL3c in FIG. In other words, the warm air from the air conditioning unit 90 can be locally blown out to the driver 72 holding the steering wheel 80.

  Further, since each of the rotating doors 15 and 16 can be continuously rotated, for example, as shown in FIG. 9, the door plate portions 152 and 162 may be positioned so as to be inclined with respect to the vehicle longitudinal direction DR1. By doing in this way, the said blowing air distribution which the distribution change apparatus 14 changes will contain the wind direction distribution of the blowing air which blows off from the blower outlet 121. FIG.

  More specifically, as shown in FIG. 9, one surface 152 a and the other surface 152 b of the right door plate portion 152 of the right door 15 function as a guide surface that guides the air flowing through the blowing air passage 123. At the same time, the one surface 162 a and the other surface 162 b of the left door plate portion 162 of the left door 16 also function as guide surfaces for guiding the air flowing through the blown air passage 123.

  Then, the distribution changing device 14 changes the inclinations θ1 and θ2 of the guide surfaces 152a, 152b, 162a, and 162b with respect to the vehicle width direction DR3 as the rotary doors 15 and 16 rotate, thereby distributing the wind direction of the blown air. To change.

  For example, when the distribution changing device 14 is in the third state DP3 of FIG. 7, the entire blown air is in a wind direction substantially along the vehicle longitudinal direction DR1, as indicated by arrows FL1b, FL2b, FL3b. On the other hand, when the distribution changing device 14 is in the state of FIG. 9, the wind direction in the central portion of the air blown from the air outlet 121 is substantially the wind direction along the vehicle longitudinal direction DR1 as indicated by the arrow FL1d. The wind direction does not change much. However, in the state shown in FIG. 9, the direction along the vehicle front-rear direction DR1 as indicated by the arrow FL2d in a region closer to one side (specifically, the right side) of the vehicle width direction DR3 in the air blown from the outlet 121. More, the wind direction faces one side of the vehicle width direction DR3. Further, in the region of the blown air that is closer to the other side (specifically, the left side) of the vehicle width direction DR3, the other side of the vehicle width direction DR3 is more than the direction along the vehicle front-rear direction DR1, as indicated by the arrow FL3d. The wind is turned.

  In this way, the distribution changing device 14 changes the wind direction distribution in order to change the wind direction of the blown air in the central portion of the outlet 121 in the vehicle width direction DR3 and one side of the central portion in the vehicle width direction DR3. It includes changing the difference between the wind direction of the blown air on the other side. Further, to change the wind direction distribution, the wind direction of the blown air on one side with respect to the central part in the vehicle width direction DR3 in the blower outlet 121 and the blown air on the other side with respect to the central part in the vehicle width direction DR3. It also includes changing the difference from the wind direction.

  Since the distribution changing device 14 has such a function of changing the wind direction distribution, it is possible to adjust the wind direction according to the preference of the driver 72 by the operation of the distribution changing device 14.

  As described above, according to the present embodiment, the blowout portion 12 is formed with the blowout port 121 that is opened at the hood lower surface 782 so as to blow the blown air from the air conditioning unit 90 to the rear of the vehicle. Further, the distribution changing device 14 changes the blown air distribution, which is a distribution of at least one of the wind speed, temperature, and wind direction of the blown air blown out from the blower outlet 121. In the present embodiment, the blown air distribution includes a wind speed distribution and a wind direction distribution of the blown air.

  Therefore, compared with the case where the blowing air distribution does not change, it becomes easier to improve the driver's comfort by changing the blowing air distribution. Therefore, when the air blowing device 10 blows air from the front of the driver 72 to the driver 72, there is an opportunity to blow the wind required from the viewpoint of improving the comfort of the driver 72 to the driver 72. It is possible to do more.

  That is, since the wind speed distribution and the wind direction distribution of the blown air can be changed by the air blowing device 10, an air flow suitable for the driver 72 can be provided.

  For example, immediately after boarding in summer, the distribution changing device 14 is switched to the first state DP1 in FIG. 6 during the cooling operation of the air conditioning unit 90, and the wind is blown intensively to the face or chest of the driver 72. Thus, the comfort of the driver 72 is improved. After that, if the concentrated wind on the face or chest becomes uncomfortable for the driver 72, or if the driver 72 feels hot, The wind direction of the air blown from the outlet 121 can be changed to the hand of the driver 72. When the wind direction is changed to the hand of the driver 72 as described above, it is possible to prevent the blowing air from being blown almost to the eyes, face, and chest of the driver 72.

  As another situation, the air blowing device 10 can be used even in winter. For example, when riding in winter, it may be difficult for the hand of the driver 72 and the steering wheel 80 to cool and grip firmly. In such a case, the distribution changing device 14 is switched to the second state DP2 in FIG. 8 during the heating operation of the air conditioning unit 90, and the air blowing device 10 moves the air from the outlet 121 toward the hand of the driver 72. It is possible to warm the hand like a spot by blowing out. At this time, since the blown air does not go to the face of the driver 72, it is possible to reduce the dryness of the eyes and the stuffiness of the face, thereby contributing to the improvement of comfort.

  Further, it is possible to change the distribution of the blown air with a single drive mechanism without providing a dedicated outlet for blowing air to the driver's 72 hand and chest, and an on-off valve for opening and closing it. Further, each of the rotating doors 15 and 16 of the distribution changing device 14 has a configuration that can also serve as an airflow guide plate at the time of cool-down when air is blown out toward the center of the driver 72. Therefore, it can be provided at a low cost.

  Further, according to the present embodiment, the blown air distribution changed by the distribution changing device 14 includes the wind speed distribution of the blown air from the blower outlet 121. Accordingly, it is possible to improve the comfort of the driver 72 according to the change in the wind speed distribution.

  Further, according to the present embodiment, the blown air distribution changed by the distribution changing device 14 includes the wind direction distribution of the blown air from the blower outlet 121. Accordingly, it is possible to improve the comfort of the driver 72 according to the change in the wind direction distribution.

  Further, according to the present embodiment, the blown air distribution is a distribution that extends in the vehicle width direction DR3. Therefore, it is easy to apply to the air blowing device 10 having the air outlet 121 formed so as to expand in the vehicle width direction DR3 as in the present embodiment.

  Further, according to the present embodiment, to change the distribution of the blown air, the wind speed of the blown air at the central part in the vehicle width direction DR3 of the blower outlet 121 and the one with respect to the central part in the vehicle width direction DR3. It includes changing the difference between the wind speed of the blown air on the side and the other side. Therefore, the change in the wind speed distribution of the blown air can be a change suitable for improving the comfort of the driver 72.

  Moreover, according to this embodiment, in order to change the said blowing air distribution, the wind direction of the blowing air in the center part in the vehicle width direction DR3 among the blower outlets 121, and one side with respect to the center part in the vehicle width direction DR3 It includes changing the difference between the wind direction of the blown air on the side and the other side. Therefore, the change in the wind direction distribution of the blown air can be made a change suitable for improving the comfort of the driver 72.

  In addition, according to the present embodiment, the distribution changing device 14 has the rotating doors 15 and 16 that are provided in the blowing air passage 123 and rotate. And the distribution change apparatus 14 changes the blockage range blocked | closed by the rotation doors 15 and 16 in the blowing air path 123 with rotation of the rotation doors 15 and 16, thereby changing the wind speed distribution of the blown air. Change. Therefore, it is possible to easily realize a configuration in which the distribution changing device 14 changes the wind speed distribution and the wind direction distribution of the blown air.

  Further, according to the present embodiment, the two rotary doors 15 and 16 each have one surface 152a and 162a and the other surfaces 152b and 162b as guide surfaces for guiding the air flowing through the blown air passage 123, respectively. . And the distribution change apparatus 14 changes the wind direction distribution of blowing air by changing the inclination of the guide surface with respect to vehicle width direction DR3 with rotation of the rotation doors 15 and 16. FIG. Therefore, the wind direction distribution of the blown air can be easily changed by the rotation of the rotation doors 15 and 16.

  Further, according to the present embodiment, the blown air passage 123 includes a plurality of divided passages 123a, 123b, and 123c that are arranged side by side in the vehicle width direction DR3. And the distribution change apparatus 14 changes the said blowing air distribution in connection with changing the mutual ratio of each opening degree of the some division | segmentation channel | path 123a, 123b, 123c. Accordingly, the two rotating doors 15 and 16 of the distribution changing device 14 can be arranged in the blown air passage 123. In short, it is possible to arrange the rotating doors 15 and 16 on the upstream side of the air flow from the air outlet 121 so that the rotating doors 15 and 16 are hardly exposed from the air outlet 121.

  Further, according to the present embodiment, the plurality of divided passages 123a, 123b, 123c are a central divided passage 123a and a one-side divided passage 123b disposed on one side in the vehicle width direction DR3 with respect to the central divided passage 123a. And the other side divided passage 123c arranged on the other side in the vehicle width direction DR3 with respect to the central divided passage 123a. And the blowing air which blows off through the one side division | segmentation channel | path 123b is blown out by the one side of the vehicle width direction DR3 with respect to the blowing air which blows off through the center division | segmentation channel | path 123a. The blown air blown out through the other divided passage 123c is blown out toward the other side in the vehicle width direction DR3 with respect to the blown air blown out through the central divided passage 123a. Therefore, it is possible to blow out the respective blown air blown to different locations in the vehicle compartment in different states.

  Further, according to the present embodiment, the air outlet 121 blows out at least a part of the blown air from the air conditioning unit 90 to the rear of the vehicle through the inside of the steering wheel 80. Therefore, it is possible to apply the air blown from the air outlet 121 to the driver 72.

(Second Embodiment)
Next, a second embodiment will be described. In the present embodiment, differences from the first embodiment will be mainly described. Further, the same or equivalent parts as those of the above-described embodiment will be described by omitting or simplifying them. The same applies to the third and later embodiments described later.

  As shown in FIG. 10, in this embodiment, the distribution changing device 14 has a plurality of heaters 201, 202, 203 instead of the rotating doors 15, 16. In this respect, the present embodiment is different from the first embodiment.

  Specifically, the plurality of heaters 201, 202, 203 of the distribution changing device 14 are arranged in the blown air passage 123. That is, the plurality of heaters 201, 202, and 203 are disposed on the upstream side of the air flow with respect to the air outlet 121, and heat the air blown out from the air outlet 121.

  Further, the blowout portion 12 has a plurality of partition walls 125a and 125b with the vehicle width direction DR3 as the thickness direction. Since the plurality of partition walls 125a and 125b are arranged side by side in the vehicle width direction DR3 in the blown air passage 123, the plurality of blown air passages 123 are arranged in the same manner as in the first embodiment. The divided passages 123a, 123b, and 123c are included.

  Specifically, the one-side partition wall 125a disposed on one side in the vehicle width direction DR3 among the plurality of partition walls 125a and 125b is disposed between the central divided passage 123a and the one-side divided passage 123b. . Moreover, the other side partition wall 125b arrange | positioned among the some partition walls 125a and 125b at the other side of the vehicle width direction DR3 is arrange | positioned between the center division | segmentation channel | path 123a and the other side division | segmentation channel | path 123c. In the present embodiment, since the plurality of partition walls 125a and 125b extend to the air outlet 121, the air outlet 121 is also divided into a plurality (specifically, three).

  The plurality of heaters 201, 202, and 203 are disposed so as to correspond to the plurality of division passages 123a, 123b, and 123c, respectively. Accordingly, the plurality of heaters 201, 202, and 203 are arranged side by side in the vehicle width direction DR3.

  Specifically, the plurality of heaters 201, 202, 203 include a central heater 201, one side heater 202, and the other side heater 203. The central heater 201 heats the air flowing to the central division passage 123a. Moreover, the one side heater 202 is arrange | positioned with respect to the center heater 201 in the one side of the vehicle width direction DR3, and heats the air which flows into the one side divisional passage 123b. The other side heater 203 is disposed on the other side in the vehicle width direction DR3 with respect to the central heater 201, and heats the air flowing to the other side division passage 123c.

  Due to the arrangement of the heaters 201, 202, 203, the plurality of heaters 201, 202, 203 warm the air sent from the air conditioning unit 90 and flow it to the outlet 121. And the distribution change apparatus 14 changes the temperature distribution of the blowing air which blows off from the blower outlet 121 by changing the temperature of several heater 201,202,203, respectively.

  That is, the blown air distribution changed by the distribution changing device 14 in the present embodiment is the temperature distribution of the blown air blown from the blower outlet 121. Therefore, in this embodiment, for example, it is possible to change the temperature arrival of each part according to the preference of the driver 72.

  In the air blowing device 10 configured as described above, for example, at the time of cool-down for quickly eliminating heat, the air-conditioning unit 90 is air-cooled so that air cooled by the air-conditioning unit 90 is blown out with a large air volume. It flows through the blowing air passage 123 toward 121. In this case, the power sources of the plurality of heaters 201, 202, and 203 are all turned off. As a result, the cool air from the air conditioning unit 90 flows as indicated by arrows FL1e, FL2e, and FL3e, and blows out from the face of the driver 72 to the throat with a large air volume from the air outlet 121.

  Further, at the time of steady operation in which the cooling of the passenger compartment is maintained while maintaining the current state, only the driver's 72 hand may be hot due to solar radiation. At that time, the cold air from the air conditioning unit 90 flows through the air outlet passage 123 toward the air outlet 121. At this time, the one side heater 202 and the other side heater 203 are turned off while the central heater 201 is turned on, and the central heater 201 warms the air flowing to the central divided passage 123a. As a result, the air heated to the normal temperature reaches the face of the driver 72 as indicated by an arrow FL1e, and at the same time, the cool air from the air conditioning unit 90 is held and the steering wheel 80 is held as indicated by the arrows FL2e and FL3e. It reaches the driver 72's hand.

  Further, immediately after boarding in winter, the air conditioning unit 90 is operated for heating, but it takes a certain amount of time to blow out warm air. Therefore, the air before being heated by the air conditioning unit 90 (that is, cold air) flows toward the outlet 121 and flows into the outlet air passage 123. At this time, the central heater 201 is turned off, while the one side heater 202 and the other side heater 203 are turned on, the one side heater 202 warms the air flowing to the one side divided passage 123b, and the other side heater 203 is the other side. The air flowing to the side division passage 123c is warmed. As a result, the air from the air conditioning unit 90 reaches the face of the driver 72 as indicated by the arrow FL1e while being cold. At the same time, the air heated by the one-side heater 202 and the other-side heater 203 reaches the hand of the driver 72 holding the steering wheel 80 as indicated by arrows FL2e and FL3e, so that the hand is locally warmed.

  Further, when the vehicle interior itself is warmed by the air conditioning of the air conditioning unit 90 during vehicle operation in winter, the driver 72 may feel sleepy due to the warmth of the vehicle interior. In such a case, by cooperating with the air conditioning unit 90, the air blowing device 10 can blow out cold air to the face of the driver 72 and send warm air to the hand.

  As can be seen from the operation example of the air blowing device 10 as described above, in order to change the blown air distribution in the present embodiment, the temperature of the blown air at the central portion of the blower outlet 121 in the vehicle width direction DR3 In the vehicle width direction DR3, the difference with the temperature of the blown air on one side with respect to the central portion is included. And in order to change the said blowing air distribution, the temperature of the blowing air in the center part in the vehicle width direction DR3 among the blower outlets 121, and the temperature of the blowing air in the other side with respect to the center part in the vehicle width direction DR3, It also includes changing the difference.

  In the present embodiment, the effects produced from the configuration common to the first embodiment described above can be obtained as in the first embodiment.

  Further, according to the present embodiment, the blown air distribution changed by the distribution changing device 14 includes the temperature distribution of the blown air from the blower outlet 121. Therefore, it is possible to improve the comfort of the driver 72 according to the change in the temperature distribution.

  Moreover, according to this embodiment, in order to change the said blowing air distribution, the temperature of the blowing air in the center part in the vehicle width direction DR3 among the blower outlets 121, and one side with respect to the center part in the vehicle width direction DR3 It includes changing the difference between the temperature of the blown air on the side and the other side. Therefore, the change in the temperature distribution of the blown air can be made a change suitable for improving the comfort of the driver 72.

  Further, according to the present embodiment, the distribution changing device 14 has the plurality of heaters 201, 202, 203 arranged on the upstream side of the air flow with respect to the outlet 121, and the plurality of heaters 201, 202, 203 are blown out. Heat the air. Therefore, even in a situation where the air conditioning unit 90 cannot supply warm air, the air blowing device 10 can blow warm air. For example, warm air can be blown out to the driver 72 before the air in the air conditioning unit 90 is warmed to a specified temperature during warm-up in winter.

  Further, according to the present embodiment, the plurality of heaters 201, 202, 203 are arranged side by side in the vehicle width direction DR3. The distribution changing device 14 changes the temperature distribution of the blown air by changing the temperatures of the plurality of heaters 201, 202, and 203, respectively. Therefore, the temperature distribution of the blown air can be easily changed by adjusting the temperatures of the plurality of heaters 201, 202, and 203, respectively.

That is, the left door 23 has a left door rotation shaft 231 corresponding to the right door rotation shaft 221 and a left door plate portion 232 corresponding to the right door plate portion 222. Then, the left door plate portion 232 slides in the vehicle width direction DR3 as indicated by the arrow SL2 in conjunction with the rotation of the left door rotation shaft 231 indicated by the arrow RT2.

  Further, since the two slide doors 22 and 23 of the distribution changing device 14 operate in conjunction with each other so as to be symmetrically arranged in the vehicle width direction DR3, the air blown from the air outlet 121 is the first embodiment. Similarly, the air flow is symmetrical in the vehicle width direction DR3.

  In the present embodiment, as shown in FIG. 14, the distribution changing device 14 has a single heater 204 instead of the three heaters 201, 202, 203 of the fourth embodiment. In this respect, the present embodiment is different from the fourth embodiment.

  Specifically, the heater 204 of the present embodiment is formed so as to expand in the vehicle width direction DR3 within the blown air passage 123. Specifically, the heater 204 is arranged so as to cover the whole of the plurality of divided passages 123a, 123b, 123c in the vehicle width direction DR3. When the heater 204 is energized, the temperature of the heater 204 is increased so as to be uniform in the vehicle width direction DR3, for example.
