  Thus, in the air blowing device for vehicle interiors of this type, if the amount of rotation in the parallel state of all the wind direction adjusting plates is appropriately adjusted, the axis (cylinder) of the air guiding path can be opened with the air blowing opening opened. The angle of inclination of each wind direction adjusting plate with respect to the body axis can be adjusted, and the blowing direction (wind direction) of the air flow (wind) blown from the air outlet is adjusted by each wind direction adjusting plate In this case, however, between the leading edge of the wind direction adjusting plate located on one side and the inner peripheral surface of the cylinder, and between the rear end edge of the wind direction adjusting plate located on the other side and the inner peripheral surface of the cylinder A gap is formed in each of the two, and an air flow is blown out from these gaps.

  From the first gap formed between the leading edge of the wind direction adjusting plate located on one side and the inner peripheral surface of the cylinder, the air travels straight across the air flow directed at the surface of the wind direction adjusting plate. As a result, the direction of the air flow by the wind direction adjusting plate is greatly disturbed. Further, air that travels straight from the second gap formed between the rear edge of the wind direction adjusting plate located on the other side and the inner peripheral surface of the cylindrical body without being affected by the inclination angle of the wind direction adjusting plate. A flow blows out and disturbs the directivity direction of the air flow by the wind direction adjusting plate.

  One of the inventors of the present invention pays attention to the fact that the air flow blown out straight from the first gap greatly disturbs the finger direction of the air flow whose wind direction is adjusted by each wind direction adjusting plate, Although the present inventors have already proposed means for coping with such a problem, the present inventors have also proposed a blown air flow directed by each wind direction adjusting plate for the air flow blown in the straight traveling direction from the second gap. It has been learned that it has a great influence on the direction of direction. Accordingly, an object of the present invention is to suppress the influence on the directing direction of the air flow whose wind direction is adjusted, which is caused by the blown air flow blown out from the second gap.

  The present invention relates to a vehicle interior air blowing device. A vehicle interior air blowing device to which the present invention is applied includes a cylindrical tube forming an air guiding path, and an air outlet on the tip side of the tube that is rotatably supported inside the tube. A plurality of wind direction adjusting plates that open and close and a connecting member that connects the wind direction adjusting plates to each other and rotates the wind direction adjusting plates in conjunction with each other, and the wind direction adjusting plates are connected to the axis of the cylinder. On the other hand, by adjusting the rotation between a range of a parallel state that is substantially parallel to each other and a series state that is substantially orthogonal to each other, the blowing direction of the air flow that is blown out by opening the air outlet of the cylindrical body A vehicle interior air blowing device that exhibits a wind distribution function that adjusts the air flow and a wind blocking function that closes the air outlet of the cylindrical body and blocks air flow.

  Therefore, the air blowing device for a vehicle interior according to the present invention is a vehicle air blowing device of the above-described type, and the cylinder body adjusts each wind direction so as to open the air blowing port in a closed state. When the plate is rotated, the air flow guide plate is provided with a rear end edge facing a gap formed so as to be gradually separated from the inner peripheral surface of the cylindrical body, and the air flow guide plate opens the air outlet. It functions to induce an air flow on the surface side of the wind direction adjusting plate.

  In the vehicle interior air blowing device according to the present invention, the air flow guide plate has an arcuate shape that curves along the inner peripheral surface of the cylindrical body, and bends and extends toward the surface side of the wind direction adjusting plate. It can be configured.

  In the air blowing device for a vehicle interior according to the present invention, if the amount of rotation of all the wind direction adjusting plates in the parallel state is appropriately adjusted, each wind direction adjusting plate with respect to the axis of the air guide path can be opened with the air blowing port opened. Can be adjusted, and the blowing direction (wind direction) of the air flow blown out from the air blowing port can be adjusted by each wind direction adjusting plate. In this case, also in the air blowing device for vehicle interior according to the present invention, as described above, the rear end edge and the tube of the wind direction adjusting plate located on the other side are the same as the conventional air blowing device for vehicle interior of this type. A gap is formed between the inner wall surfaces of the body, and an air flow is blown out from the gap.

  However, the air blowing device for vehicle interior according to the present invention includes an air flow guide plate facing the gap on the inner peripheral surface side of the cylindrical body forming the air guide path. The air flow guide plate is located opposite to the rear end portion of the wind direction adjusting plate located on the other side, and the air flow blown from the gap formed when the air outlet is opened Functions to guide to the surface side of the plate. For this reason, the air flow guide plate regulates the directivity of the air flow that blows out through the gap in the straight direction, and guides the air flow to the surface side of the wind direction adjusting plate. As a result, the air flow is directed and blown in a direction along the inclination angle of the air direction adjusting plate.

  In other words, according to the air blowing device for vehicle interior according to the present invention, there is no formation of an air flow that goes straight through the gap, and the entire air flow that is blown out from between the respective wind direction adjusting plates of the air outlet is The wind is blown substantially evenly in the direction directed by the wind direction adjusting plate without being affected by the straight air flow. In the vehicle interior air blowing device according to the present invention, the air flow guide plate is bent in the shape of an arc that curves along the inner peripheral surface of the cylindrical body, and is bent toward the surface side of the wind direction adjusting plate. By making it the structure extended, the above-mentioned effect can be exhibited more notably.

  The present invention relates to a vehicle interior air blowing device that is installed on an instrument panel or the like in a vehicle compartment and functions as a center register, a side register, a lower register, a side defroster, or the like. 1 to 6 show a register which is an embodiment of an air blowing device for a passenger compartment according to the present invention. 1 is a side view of the register, FIG. 2 is a front view of the register when the air outlet is fully closed, FIG. 3 is a rear view of the register, and FIG. 4 is a state where the air outlet of the register is fully closed.

  The register 10 includes a case 11 that is a cylindrical tube, a first fin 12 and a second fin 13 that are main wind direction adjusting plates, a connecting rod 14 that connects the fins 12 and 13 to each other, and a secondary wind direction. A third fin 15 serving as an adjustment plate is provided, and a cylindrical retainer 16 that receives the fitted case 11 and an annular cover 17 that is fitted to the tip of the case 11 are provided.

  The case 11 forms a cylindrical air guide path AR, and is mainly composed of a cylindrical case main body 11a having a predetermined length, and an opening on the front end side constitutes an air outlet, and on the rear end side. The opening constitutes an air inlet. The opening on the rear end side of the case body 11a is formed with an arc-shaped rod-shaped support arm 11b extending from the edge of the case body 11a. In other words, the center part of the support arm 11b in the length direction, in other words, the case body A portion on the central axis of 11a is formed in the support portion 11c. The support portion 11c includes a fitting hole that opens rearward.

  The first fin 12 has a substantially elliptical outer peripheral shape and has a flat plate shape. The first fin 12 has a substantially elliptical flat plate-like fin main body 12a and is protruded above the central portion on the back side of the fin main body 12a. A connecting arm 12b and a pair of left and right support arms 12c projecting from left and right tip portions on the long diameter side of the outer peripheral edge of the fin body 12a are provided. Also. Similar to the first fin 12, the second fin 13 has a substantially elliptical outer shape and a stepped flat plate shape. The substantially fin-shaped stepped fin main body 13 a and a fin main body are provided. 13a is provided with a connecting arm 13b projecting above the central portion on the back side of the rear side 13a and a pair of left and right support arms 13c projecting at the left and right tip portions on the long diameter side of the outer peripheral edge of the fin body 13a. . An upper surface portion of the fin body 13a of the second fin 13 in the figure is formed in a recess 13a1 that is recessed on the back side. The recess 13a1 is formed in a shape in which the back surface of the lower side portion of the fin body 12a of the first fin 12 is fitted and overlapped.

  In the first fin 12 and the second fin 13, the support shafts provided on the left and right support arms 12 c and 13 c are rotatably fitted in the support holes provided on the inner peripheral surface of the case 11, thereby enabling the case 11. It is arrange | positioned so that rotation is possible. Further, the first fin 12 and the second fin 13 are configured to rotate in conjunction with each other by connecting the connecting arms 12 b and 13 b with the connecting rod 14. As shown in FIG. 4, the first fin 12 and the second fin 13 supported in this way can be partially fitted and superposed on the lower side and the upper side in the drawing.

  The third fin 15 is an auxiliary wind direction adjusting plate for the first fin 12 and the second fin 13, and like these fins 12, 13, the outer peripheral shape is substantially elliptical and has a flat plate shape. Fixing arms 15b and 15c are provided on the surface side of the elliptical and flat fin body 15a at the left and right ends thereof so as to protrude perpendicularly to the surface. Each of the fixing arms 15 b and 15 c is fixed to the second fin 13 by fixing the tip thereof to the inner surface of the left and right outward flange portions of the second fin 13. The third fin 15 is disposed in the case 11 integrally with the second fin 13 while being fixed to the second fin 13. In this fixed state of the third fin 15, as shown in FIGS. 4 and 6, the third fin 15 is located in a parallel state with a predetermined distance from the back surface of the second fin 13, and is the same as the second fin 13. The second fin 13 is integrally rotated by the same amount around the rotation center A2. The rotation center of the first fin 12 is the rotation center A1.

  Therefore, the assembly in which the first fin 12, the second fin 13, and the third fin 15 are assembled in the case 11 functions as a register. In the present embodiment, the assembly is referred to as an inner register 10a. The inner register 10a is fitted into the cylindrical body 16a of the retainer 16 and assembled and received in the retainer 16. The inner body 10a has an annular shape on the outer peripheral edge of the opening on the front end side of the case body 11a. A cover 17 is fitted. The cover 17 forms an opening on the front end side of the case body 11a at the air outlet. Accordingly, the register 10 includes an inner register 10a and a retainer 16 that is fitted and received with the inner register 10a. The retainer 16 is integrated with the case 11 constituting the inner register 10a to form an air guide path AR.

  The retainer 16 is mainly composed of a cylindrical retainer main body 16a, and the opening on the front end side is fully open, so that the case 11 can be fitted into the inner hole. Further, the opening on the rear end side of the retainer body 16a is covered with a honeycomb-like mesh body 16b, and a support portion 16c is formed at the center of the mesh body 16b. The support portion 16c includes a protruding portion that protrudes toward the distal end side. When the case 11 is fitted to the retainer main body 16a, the support portion 16c is fitted into a fitting hole of the support portion 11c included in the case 11 so that the case 11 has a circumference. It is supported to rotate in the direction. The retainer main body 16a includes an annular step portion (not shown) at an intermediate portion in the longitudinal direction inside the inner hole. The step portion is formed in a concavo-convex shape in which the entire circumference of the front side end surface is continuous. When the case 11 is fitted in the inner hole of the retainer main body 16a, the end surface of the stepped portion elastically receives each leg portion of a spring (not shown) assembled to the rear end surface of the case main body 11a. The case 11 is allowed to rotate intermittently in the circumferential direction. In other words, the inner register 10a rotates intermittently in the retainer 16 in the circumferential direction.

  In the inner register 10 a constituting the register 10, a guide plate 18 facing the surface side of the rear end portion of the first fin 12 is provided on the arrangement side of the first fin 12 at the rear end portion of the case 11. Yes. The guide plate 18 corresponds to the air guide plate in the present invention, and is formed integrally with the case 11. The guide plate 18 extends from the rear end of the case 11 to an arcuate plate main body 18a extending rearward along the inner peripheral surface of the retainer main body 16a of the retainer 16, and bent forward from the rear end of the plate main body 18a. The guide plate portion 18b is composed of a guide plate portion 18b. The guide plate portion 18b has substantially the same tilt angle as the tilt angle of the first fin 12 when both the fins 12 and 13 are rotated to the half-open state. Is formed. In other words, the guide plate portion 18b is positioned opposite to the rear end portion of the first fin 12 on the inner peripheral surface side of the case 11 and the retainer 16 that form the air guide path AR. It faces a gap (second gap B2 described later) formed between the rear end edge and the inner peripheral surface of the case 11 and / or the retainer 16.

  In the register 10, by adjusting the amount of rotation of the fins 12 and 13, the air outlet on the front end side of the case body 11 a of the case 11 is shielded in the same manner as a conventional register of this type. A shut-off function (see FIGS. 2 and 4) for shutting off the air flow from the air outlet, and an arrangement for opening the air air outlet and directing the air flow from the air outlet in a desired direction. A wind function (refer FIG. 5 and FIG. 6) can be exhibited.

  In the register 10, the air outlet is shielded by the fins 12 and 13 as shown in FIGS. 2 and 4, and the fins 12 and 13 are interlocked as shown in FIGS. 5 and 6. And then released by rotating. The figure shows a state in which the air outlet is substantially half-opened, and the inclination of the fin bodies 12a, 13a of the fins 12, 13 is approximately 45 degrees with respect to the longitudinal axis L of the air guiding path AR. It is inclined at an angle. When the air outlet of the register 10 is opened in such a state, an air flow is blown out along the inclination of the fin bodies 12a and 13a of the fins 12 and 13, and the air flow has a desired inclination. Wind direction of direction. In the register 10, the fin bodies 12 a and 13 a of the fins 12 and 13 can be rotated up to an angle parallel to the axis L, and in this state, the air outlets are fully opened. . When the air outlet of the register 10 is opened in such a fully open state, an air flow is blown out along the fin bodies 12a and 13a of the fins 12 and 13, and the air flow is desired to travel substantially straight. Wind direction.

  In the register 10, the inner register 10 a is fitted in the inner hole of the retainer 16 and assembled, and when the inner register 10 a is fitted to the retainer 16, the inner register 10 a is circumferential. It is set as the structure received so that it can rotate intermittently. For this reason, the inner register 10a is appropriately intermittently rotated in the circumferential direction in the retainer 16 to adjust the position thereof, whereby the wind direction of the airflow blown from the air outlet of the inner register 10a is changed upward and downward. Direction, right direction, left direction, etc. can be selectively adjusted in all directions.

  By the way, in the register 10, when the fins 12 and 13 are pivoted to open the air outlet, as shown in FIG. 6, the tip edge of the fin body 13 a of the second fin 13 and the case 11. A first gap B1 is formed between the inner peripheral surface, and a second gap B2 is formed between the rear end edge of the fin body 12a of the first fin 12 and the inner peripheral surface of the case 11. . For this reason, when the air outlet is opened, an air flow is also blown out from the gaps B1 and B2. However, the air flow blown out from the gaps B1 and B2 has a function of adjusting the wind direction of the fins 12 and 13. Is not enough. In the conventional register of this type, the air flow blown out from the gaps B1 and B2 is a linear flow parallel to the longitudinal axis L of the air guide path AR. For this reason, the airflow blown out straight from the first gap B1 intersects the airflow whose wind direction is adjusted by the second fin 13 and disturbs the directing direction of the airflow. The air flow blown out straight from the second gap Bb is adjusted in the wind direction by the first fin 12 and flows on one side of the air flow, thereby disturbing the directing direction of the air flow.

  Therefore, in the conventional register of this type, it is required to regulate the blowing of the air flow that blows out straight from the gaps B1 and B2. In the register 10, as a means for restricting the blowing of the air flow blown straight from the first gap B 1, a means for disposing the third fin 15 is adopted, and the straight movement is made straight from the second gap B 2. The means for restricting the blowing of the air flow blown out is taken as the means for disposing the guide plate 18. Therefore, hereinafter, the function of the third fin 15 will be described first, and then the function of the guide plate 18 will be described. The means for disposing the third fin 15 has already been proposed by one of the present inventors, and the means for disposing the guide plate 18 is the most characteristic feature of the register 10. .

  In the register 10, when the first fin 12 and the second fin 13 are rotated so as to open the air outlet, the first fin 12 is rotated around the rotation fulcrum A1 as shown in FIG. And the 2nd fin 13 rotates centering on rotation fulcrum A2 in connection with this. In this case, when the second fin 13 rotates, the front end edge of the fin main body 13a of the second fin 13 is gradually separated from the inner peripheral surface of the case main body 11a of the case 11 in accordance with the amount of rotation. And a gap (first gap B1) is formed between the inner peripheral surfaces of the case body 11a. The gap B1 blows an air flow, but the air flow does not receive a wind direction adjustment function on the back side of the second fin 13 and becomes an air flow that goes straight along the axis L of the air guide path AR. Crossing with the air flow directed by .13 will greatly hinder the flow of the directed air flow in the same direction, causing a problem of significantly changing the adjusted wind direction. The third fin 15 closes the gap B1 as much as possible, and suppresses the generation of an air flow that goes straight from the gap B1 and blows out as much as possible.

  When the first fin 12 and the second fin 13 are in a series state in which the first fin 12 and the second fin 13 are substantially orthogonal to the axis L of the case body 11a and the air outlet of the register 10 is closed, On the back side of the fixed second fin 13, the second fin 13 is positioned in parallel with a predetermined distance. Therefore, when the first fin 12 and the second fin 13 are rotated, the third fin 15 is integrated with the second fin 13 and is parallel to the fin 13 around the rotation center A2 of the second fin 13. Hold and rotate. As a result, the third fin 15 operates so as to largely shield the gap B1 formed by the tip edge of the fin body 13a of the second fin 13, and the shielding state of the gap B1 by the further rotation of the second fin 13 In a state where the second fin 13 is parallel to the axis L, the shielding state of the gap B1 is completely solved. The third fin 13 largely suppresses the blowing of the air flow that travels straight from the gap B1 by such a turning operation.

  On the other hand, in the register 10, when the first fin 12 and the second fin 13 are rotated to open the air outlet, the rear end edge of the fin body 12a of the first fin 12 is as shown in FIG. In accordance with the amount of rotation, the case 11 is gradually separated from the inner peripheral surface of the case main body 11a, and a gap B2 (second gap B2) is formed between the rear edge and the inner peripheral surface of the case main body 11a. The gap B2 blows out an air flow, but the air flow does not receive a wind direction adjusting function on the surface side of the first fin 12, and becomes an air flow that goes straight along the axis L of the air guide path AR. .13 causes a problem that the direction of the air flow directed is greatly disturbed and the adjusted wind direction is significantly changed. The guide plate 18 faces the gap B2, and guides the air flow blown out from the gap B2 to the surface side of the fin body 12a of the first fin 12 as much as possible. In the guide plate 18, the guide plate portion 18b faces the gap B2 while maintaining a predetermined inclination angle, and faces the surface side of the rear end portion of the fin body in the first fin 12. For this reason, the guide plate portion 18b directs the air flow blown out from the gap B2 to the surface side of the fin body 12a in the first fin 12 as much as possible, and greatly suppresses the blowout of the air flow going straight from the gap B2. .
