[0004] In recent years, the installation of wiper units, airbags, and the like within the cowl has tended to narrow the air passage within the cowl. This has resulted in a relatively high flow rate of outside air within the cowl, making it difficult to effectively separate the liquid contained in the outside air from the air. For this reason, it is desirable for the cowl structure to have a structure that can effectively separate the liquid from the air.

[0005] SUMMARY OF THE INVENTION In consideration of the above, an object of the present invention is to provide a cowl structure for a vehicle that can effectively separate liquid and air. [Means for solving the problem]

DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, a vehicle cowl structure 10 according to this embodiment (hereinafter simply referred to as the cowl structure 10) will be described with reference to the drawings. Note that the arrow UP shown as appropriate in the drawings indicates the upper side of the vehicle (automobile) V to which the cowl structure 10 is applied, the arrow FR indicates the front side of the vehicle, and the arrow RH indicates the right side of the vehicle (one side in the vehicle width direction). In the following description, when the up-down, front-rear, and left-right directions are used, they refer to the up-down direction of the vehicle, the front-rear direction of the vehicle, and the left-right direction of the vehicle unless otherwise specified.

[0010] (Overall structure) As shown in FIG. 1, the cowl structure 10 is provided in front of the lower end (front end) of a windshield glass 40 of the vehicle V, and is disposed below the rear end of a hood 42 of the vehicle V. The cowl structure 10 is formed in a generally cylindrical shape extending in the vehicle width direction as a whole, and the interior of the cowl structure 10 is configured as a cowl duct portion 16 (see FIG. 3). The cowl structure 10 also includes an outside air inlet 14C for introducing outside air into the cowl duct portion 16, and an exhaust port 12H (see FIG. 2) for exhausting the air introduced into the cowl duct portion 16 to the vehicle interior. One end of an air conditioning duct 44 of the vehicle V is connected to the exhaust port 12H, and air exhausted from the exhaust port 12H into the air conditioning duct 44 is supplied into the vehicle interior from an air outlet 44A that forms the other end of the air conditioning duct 44. An air conditioning unit 46 is provided in the middle of the air conditioning duct 44, and when the blower fan 46A of the air conditioning unit 46 is operated, an air flow is generated in the cowl duct portion 16 from the outside air inlet 14C to the exhaust outlet 12H.

[0011] (Regarding cowl structure 10) As shown in FIGS. 1 to 4, the cowl structure 10 includes a cowl main body 12, a cowl top panel 14 serving as a cowl panel, and a gas-liquid separation mechanism 20.

[0012] (Regarding the cowl body 12) The cowl body 12 is made of a metal plate. The cowl body 12 extends in the vehicle width direction, and both longitudinal ends of the cowl body 12 are joined to apron members (not shown) that constitute frame members of the vehicle V. When viewed in the longitudinal direction, the cowl body 12 is formed in a concave shape that is open upward. Specifically, the cowl body 12 is made up of a bottom wall 12A, a front wall 12B that extends upward from the front end of the bottom wall 12A, and a rear wall 12C that extends upward from the rear end of the bottom wall 12A.

[0013] A flange 12D bent forward is formed at the upper end of the front wall 12B of the cowl main body 12. A flange 12E bent diagonally upward and rearward is formed at the upper end of the rear wall 12C of the cowl main body 12, and the flange 12E is disposed below the lower end (front end) of the windshield glass 40. The rear wall 12C of the cowl main body 12 is connected to a dash panel (not shown) that separates the engine compartment from the passenger compartment of the vehicle V. An exhaust port 12H (see FIG. 2) is formed through the rear wall 12C of the cowl main body 12 at the left end, and the exhaust port 12H is formed in a generally rectangular shape with the left-right direction as the longitudinal direction.

[0014] (Regarding cowl top panel 14) The cowl top panel 14 is made of a resin material. The cowl top panel 14 is formed in a generally elongated plate shape extending in the vehicle width direction. A flange 14A protruding forward is formed at the front end of the cowl top panel 14. The flange 14A is disposed above a flange 12D of the cowl main body 12 and is fixed to the flange 12D with a fastening member such as a clip. A panel connecting portion 14B (see FIG. 3) is formed at the rear end of the cowl top panel 14. When viewed in the longitudinal direction of the cowl top panel 14, the panel connecting portion 14B is formed in a generally U-shape that opens obliquely upward and rearward. The lower end of the windshield glass 40 is inserted into the panel connecting portion 14B, and the panel connecting portion 14B is fixed to a flange 12E of the cowl main body 12 with a fastening member such as a clip. As a result, the upper opening of the cowl main body 12 is closed by the cowl top panel 14. The interior of the cowl structure 10, which is defined by the cowl main body 12 and the cowl top panel 14, is configured as a cowl duct portion 16.

[0015] A plurality of outside air inlets 14C are formed through the right end of the cowl top panel 14. The outside air inlets 14C are formed as elongated holes with their longitudinal direction extending in the longitudinal direction and are arranged side by side at predetermined intervals in the lateral direction. This allows the inside and outside of the cowl duct portion 16 to communicate with each other through the outside air inlets 14C.

[0016] (Regarding the gas-liquid separation mechanism 20) 2 to 4, gas-liquid separation mechanism 20 is provided at the bottom of cowl duct portion 16, and is disposed between outside air inlet 14C and exhaust port 12H. Specifically, gas-liquid separation mechanism 20 is provided at the bottom of the left part of cowl body 12, and is disposed to the right of exhaust port 12H. When outside air (air) is introduced into cowl duct portion 16, gas-liquid separation mechanism 20 separates the air from liquid such as rainwater contained in the outside air.

[0017] The gas-liquid separation mechanism 20 is mainly constituted by a hollow chamber 22, which is provided in the bottom wall 12A of the cowl body 12 and disposed to the right of the exhaust port 12H. When viewed from the front, the chamber 22 is formed in a generally hollow wedge shape that protrudes diagonally upward to the right from the bottom wall 12A of the cowl body 12. Specifically, the chamber 22 is constituted by including a blocking wall 24 that forms the right wall of the chamber 22 and a partition wall 26 that extends to the left from the upper end of the blocking wall 24, and the blocking wall 24 and the partition wall 26 form the outer contour of the chamber 22.

[0018] The blocking wall 24 extends in the vertical direction and, as viewed from the front, slopes to the right (toward the outside air inlet 14C) as it extends upward. The lower end of the blocking wall 24 is bent to the right and joined to the bottom wall 12A of the cowl main body 12. The upper end of the blocking wall 24 is located in the vertical middle of the cowl duct portion 16 and is located below the cowl top panel 14 at a distance.

[0019] The partition wall 26 extends to the left from the upper end of the blocking wall 24. When viewed from the front, the partition wall 26 slopes smoothly downward in a curve toward the left, and the left end (lower end) of the partition wall 26 is disposed so as to be in contact with and joined to the bottom wall 12A of the cowl main body 12. The chamber 22 is disposed adjacent to and between the front wall 12B and the rear wall 12C of the cowl main body 12 (see FIG. 3). In other words, the chamber 22 is provided across the entire cowl duct portion 16 in the fore-and-aft direction. As a result, the interior of the chamber 22 is partitioned by the blocking wall 24, the partition wall 26, and the bottom wall 12A, front wall 12B, and rear wall 12C of the cowl main body 12, and this partitioned space is configured as a chamber 28.

[0020] Furthermore, because chamber 22 is disposed at the lower part (bottom) of cowl duct portion 16, the space above chamber 22 in cowl duct portion 16 is narrowed by chamber 22. The space above chamber 22 in cowl duct portion 16 is configured as duct narrowed portion 30, and the cross-sectional area of ​​duct narrowed portion 30 is set to be smaller than the cross-sectional area of ​​other parts of cowl duct portion 16 and to increase toward the left. Furthermore, the vertical dimension H1 of blocking wall 24 is set to be larger than the vertical dimension H2 of inlet portion 30A, which is the right end of duct narrowed portion 30 (see FIG. 3).

[0021] A plurality of (five in this embodiment) water inlets 24A (see FIG. 3 ) are formed through the lower end of the blocking wall 24. The plurality of water inlets 24A are formed as elongated holes with the vertical direction as the longitudinal direction and are aligned in the front-to-rear direction. The water inlets 24A thus communicate between the cowl duct 16 (the right space thereof) and the chamber 28, and liquid flowing to the left inside the cowl duct 16 is drawn into the chamber 28 through the water inlets 24A. A plurality of (three in this embodiment) chamber-side drainage ports 32 (see FIGS. 2 and 4 ) are formed through the bottom wall 12A of the cowl body 12 that constitutes the chamber 28, and the plurality of chamber-side drainage ports 32 are aligned in the front-to-rear direction. Liquid that flows into the chamber 28 is drained to the outside of the cowl duct 16 through the chamber-side drainage ports 32. A plurality of communication openings 26A (see FIGS. 2 and 4) (three in this embodiment) are formed through the partition wall 26 and are arranged side by side in the front-to-rear direction, thereby connecting the chamber 28 and the duct throttle section 30 through the communication openings 26A.

[0022] Furthermore, a plurality of (three in this embodiment) body-side drain ports 34 (see FIGS. 2 and 4) are formed through the bottom wall 12A of the cowl body 12 between the chamber 22 and the exhaust port 12H, and the body-side drain ports 34 are arranged in a line in the front-to-rear direction. Liquid that has passed through the duct throttle section 30 is drained from the body-side drain ports 34 to the outside of the cowl duct section 16.

[0023] Furthermore, the gas-liquid separation mechanism 20 has an inclined wall 36. The gas-liquid separation mechanism 20 is disposed to the left of the chamber 22 and the main body-side drain port 34 and to the right of the exhaust port 12H, and is disposed above the bottom wall 12A of the cowl body 12. The inclined wall 36 is inclined upward toward the left when viewed from the front, and is disposed below the exhaust port 12H. In this embodiment, the inclined wall 36 and the chamber 22 are formed integrally, and the main body-side drain port 34 vertically penetrates a portion that connects the front end of the inclined wall 36 and the rear end of the chamber 22.

[0024] (Action and effect) Next, the operation and effects of this embodiment will be described.

[0025] In the cowl structure 10 configured as described above, the outside air inlet 14C is formed at the right end of the cowl top panel 14, and the exhaust outlet 12H is formed at the left end of the cowl main body 12. When the air conditioning device 46 of the vehicle V is turned on, the blower fan 46A of the air conditioning device 46 is activated, and the air in the cowl duct portion 16 is drawn by the blower fan 46A through the exhaust outlet 12H toward the air conditioning duct 44. As a result, outside air (air) is introduced into the cowl duct portion 16 from the outside air inlet 14C, and an airflow is generated in the cowl duct portion 16 that flows from the outside air inlet 14C toward the exhaust outlet 12H.

[0026] Here, water (liquid), such as rainwater, may enter cowl duct 16 through fresh air inlet 14C along with air. At this time, airflow AR1 containing liquid water with relatively large particles flows leftward along bottom wall 12A of cowl body 12 in the lower part of cowl duct 16. As a result, as shown in FIG. 2, airflow AR1 flowing along bottom wall 12A flows into chamber 28 through water intake 24A of blocking wall 24 of chamber 22. The water that has flowed into chamber 28 is then drained to the outside of cowl duct 16 through chamber-side drain outlet 32 ​​(see arrow B in FIG. 2), and the air that has flowed into chamber 28 flows out through communication opening 26A toward duct throttle section 30 (see arrow A in FIG. 2). That is, chamber 22 separates the air from the water, which contains relatively large particles, in airflow AR1, and discharges the separated water from chamber-side drain outlet 32, while allowing the separated air to flow from communication port 26A toward exhaust port 12H. In particular, when a large amount of water flows into cowl duct portion 16, chamber 22 can effectively separate the water from the air.

[0027] On the other hand, for example, if water splashes in the cowl duct portion 16, the airflow AR2 containing the splashed water flows to the left near the center of the cowl duct portion 16 and hits the blocking wall 24 of the chamber 22. This slows down the flow velocity of the airflow AR2 that hits the blocking wall 24. Furthermore, the blocking wall 24 is inclined to the right (upstream of the airflow AR2) as it moves upward when viewed from the front. In other words, the inclined wall 36 is inclined to the left (downstream of the airflow AR2) as it moves downward when viewed from the front. Therefore, the airflow AR2 that hits the blocking wall 24 generates a vortex that flows downward along the blocking wall 24 (see the airflow AR2 shown in FIG. 2). As a result, the generated vortex separates the air and water in the airflow AR2.

[0028] The separated water flows downward along blocking wall 24 due to, for example, air flow AR2. As a result, similar to the above, water flows into chamber 28 from water intake port 24A of blocking wall 24, and the water that has flowed into chamber 28 is drained to the outside of cowl duct portion 16 from chamber-side drain outlet 32.

[0029] Furthermore, for example, atomized water having relatively small particles in the separated water is sucked into duct throttle portion 30 by airflow AR3 (see FIG. 2) flowing leftward through duct throttle portion 30 of cowl duct portion 16. The atomized water sucked into duct throttle portion 30 then flows along the bottom surface of duct throttle portion 30 (i.e., the upper surface of partition wall 26) with airflow AR3 flowing leftward. As a result, the water in airflow AR3 adheres to the bottom surface of duct throttle portion 30 (i.e., the upper surface of partition wall 26) and flows along partition wall 26 toward bottom wall 12A of cowl main body 12. The water that has flowed along partition wall 26 is then drained from main body-side drain outlet 34 to the outside of cowl duct portion 16 (see arrow C in FIG. 2).

[0030] As a result, as airflow AR3 passes through duct restriction section 30, the relatively small particles of water separated by blocking wall 24 are guided by partition wall 26 to body-side drain outlet 34 and drained to the outside of cowl duct section 16. Therefore, dry air flows as airflow AR3 from exhaust outlet 12H to air conditioning duct 44 and is supplied to the vehicle interior. Note that if water that flows along partition wall 26 in duct restriction section 30 is not drained through body-side drain outlet 34 but instead passes through body-side drain outlet 34 and flows toward exhaust outlet 12H, inclined wall 36 prevents the water from flowing toward exhaust outlet 12H. In addition, the water flows back along inclined wall 36 toward body-side drain outlet 34 and is drained from body-side drain outlet 34 to the outside of cowl duct section 16.

[0031] As described above, the gas-liquid separation mechanism 20 of the cowl structure 10 has the chamber 22, the interior of which is configured as the chamber 28. The chamber 22 is provided at the bottom of the cowl body 12 and is disposed between the outside air inlet 14C and the exhaust port 12H in the vehicle width direction. The chamber 22 is configured to include the blocking wall 24 that forms the right wall of the chamber 22 and has the water intake port 24A at its lower end, the chamber-side drain port 32, and the communication port 26A, which is disposed on the left side of the blocking wall 24 and connects the chamber 28 to the interior of the cowl body 12. Therefore, as described above, the air flow AR1 containing liquid water with relatively large particles can be caused to flow from the water intake port 24A of the blocking wall 24 into the chamber 28, thereby separating the water and air. The separated air can be returned from chamber 28 to cowl duct 16 through communication port 26A and flow toward exhaust port 12H, and the separated water can be drained to the outside of cowl duct 16 through chamber-side drain port 32. Air flow AR2 containing droplets of scattered water can be caused to collide with blocking wall 24 of chamber 22, separating the air and water from air flow AR2. That is, cowl structure 10 of this embodiment can separate water and air from air flow AR1 containing liquid water with relatively large particles within chamber 28, and can separate water and air from air flow AR2 containing droplets of scattered water by blocking wall 24. As described above, cowl structure 10 of this embodiment can effectively separate liquid from air.

[0032] Furthermore, when viewed from the front, the blocking wall 24 is inclined to the right (toward the outside air inlet 14C) as it moves upward. This allows a downward vortex to be generated when the airflow AR2 collides with the blocking wall 24, as described above. As a result, the generated vortex can effectively separate the air from the droplets of water contained in the airflow AR2.

[0033] Furthermore, the chamber 22 is disposed below and spaced apart from the cowl top panel 14, and a partition wall 26 of the chamber 22 extends to the left from the upper end of the blocking wall 24. Furthermore, the partition wall 26 slopes downward toward the left when viewed from the front, and the lower end of the partition wall 26 is connected to the bottom wall 12A of the cowl main body 12. This allows the duct throttle section 30 to be located above the chamber 22 in the cowl duct section 16. Therefore, the mist-like water with small particles separated by the blocking wall 24 can be drawn into the duct throttle section 30 by the airflow AR3 flowing through the duct throttle section 30. Furthermore, the water drawn into the duct throttle section 30 can be guided along the bottom surface of the duct throttle section 30 (the upper surface of the partition wall 26) to the bottom wall 12A of the cowl main body 12 and discharged from the main body-side drain port 34 of the cowl main body 12.

[0034] Furthermore, the vertical dimension H1 of the blocking wall 24 in the chamber 22 is set to be larger than the vertical dimension H2 of the inlet 30A of the duct throttle section 30. That is, the area of ​​the blocking wall 24 as viewed from the left and right is set to be larger than the area of ​​the inlet 30A of the duct throttle section 30. This makes it possible to increase the flow velocity of the airflow AR3 flowing through the inlet 30A of the duct throttle section 30. Therefore, the atomized water with small particles separated by the blocking wall 24 can be effectively drawn into the duct throttle section 30 by the airflow AR3.

[0035] Furthermore, an inclined wall 36 is provided at the bottom of the cowl body 12 between the main body-side drain outlet 34 and the exhaust outlet 12H. When viewed from the front, the inclined wall 36 is inclined upward toward the exhaust outlet 12H, and is disposed below the exhaust outlet 12H. As a result, even if water contained in the air flow AR3 that has passed through the duct throttle section 30 passes to the left of the main body-side drain outlet 34 without being drained through the main body-side drain outlet 34, the inclined wall 36 allows the passing water to be returned to the main body-side drain outlet 34 side and drained from the main body-side drain outlet 34.

[0036] In this embodiment, the inclination angle of the blocking wall 24 relative to the bottom wall 12A of the cowl main body 12 is not particularly specified, but the inclination angle of the blocking wall 24 can be changed as appropriate, for example, in accordance with the vertical dimensions of the cowl structure 10, etc.

[0037] Furthermore, from the viewpoint of effectively generating a vortex after the air flow AR2 collides with the blocking wall 24 and separating the air and liquid in the air flow AR2, it is desirable to arrange the blocking wall 24 so that it is inclined to the right as it goes upward, but the blocking wall 24 may also be arranged in the up-down direction when viewed from the front. Even in this case, by making the air flow AR2 collide with the blocking wall 24, the air and liquid in the air flow AR2 can be separated.

[0038] In the present embodiment, bottom wall 12A of cowl body 12 may be slightly inclined downward toward the left side when viewed from the front. This allows liquid water flowing along bottom wall 12A to flow smoothly into chamber chamber 28 of chamber 22.

[0039] Furthermore, in the present embodiment, one chamber 22 is applied to the cowl structure 10, but two chambers 22 may be applied to accommodate various vehicles. For example, as shown in Fig. 5, if the outside air inlet 14C is provided at each of both side ends in the vehicle width direction of the cowl top panel 14 and the exhaust outlet 12H is provided in the center of the cowl main body 12 in the vehicle width direction, the chambers 22 may be disposed between the outside air inlet 14C and the exhaust outlet 12H. In this case, the chambers 22 are disposed symmetrically with respect to the center of the cowl structure 10 in the vehicle width direction.

[0040] In addition, although the chamber 22 is disposed on the left side of the cowl body 12 in this embodiment, the position of the chamber 22 can be set arbitrarily. For example, the position of the chamber 22 can be set arbitrarily in accordance with the wiper operation or the airbag device mounted on the cowl body 12.

[0041] Furthermore, in the present embodiment, the chamber 22 and the inclined wall 36 are integrally formed in the gas-liquid separation mechanism 20, but the chamber 22 and the inclined wall 36 may be configured as separate bodies. [Explanation of symbols]
