Description

The present disclosure relates to registers used for air conditioning of vehicles and the like.

Conventionally, various devices for changing the blowing direction of air by fins have been proposed. For example, in the fluid blowing device of Patent Document 1 below, a plurality of adjusting fins are rotatably provided in a duct portion for blowing air. Then, by rotating a plurality of adjusting fins in the duct portion, the direction of the air blown out from the opening of the duct portion is changed.

In this type of fluid blowing device, when air is blown out from the opening of the duct portion, a lateral vortex is generated around the blown air. This lateral vortex is generated, for example, due to the speed difference between the mainstream air and the surrounding stationary air. The mainstream is diffused by the lateral vortex, or the surrounding air is drawn into the mainstream by the lateral vortex, so that the reach of the mainstream is shortened and the temperature change of the mainstream becomes large. As a result, it becomes difficult to bring air (cold air or hot air) having a desired temperature to a desired position.

Cylindrical subframes are provided at both ends of the adjusting fin of Patent Document 1. The subframe extends in the direction along the plane of the adjusting fin. The sub-frame body takes in a part of the air flowing in the duct portion and blows it out from the opening as a side flow. The sidestream blown out from the subframe disturbs the lateral vortices generated around the mainstream, suppresses the development of the lateral vortices, prolongs the reach of the mainstream, and suppresses the temperature change of the mainstream.

International Publication No. WO 2019/216157 (paragraphs 0037, 0039, FIG. 9)

As described above, it is possible to suppress the lateral vortex by the side flow, but there is a possibility that the desired effect cannot be obtained by simply attaching a member that generates the side flow to the fin. For example, when the fin is rotated to change the blowing direction of air, a part of the air flowing from the upstream hits the upstream end of the fin tilted at a predetermined angle and flows in the direction of peeling from the fin. As a result, air is not sufficiently collected in the member that generates the side flow, the reach of the main stream is shortened, and the temperature of the main stream changes significantly. Therefore, there is room for improvement in the structure of the device using the sidestream.

The present disclosure has been made to solve the above-mentioned problems, and when a sidestream member for flowing a sidestream is provided in the fin, the temperature change of the air is suppressed and the temperature is maintained, and the distance is farther. It provides a register that can blow mainstream air.

The present application includes a retainer having an air passage for blowing air in the air blowing direction, a plurality of movable fins rotatably provided in the air passage of the retainer to change the blowing direction of air blown from the retainer, and the blowing direction. A rectifying member attached to the upstream side of the plurality of movable fins in the above, and at least one of the plurality of movable fins has a secondary flow path through which a part of air flowing through the air passage is passed. It has a side flow member provided and blows out a side flow from the side flow path, and the rectifying member is attached to each of the plurality of movable fins, and a plurality of rectifying fins arranged side by side in one direction and a plurality of rectifying fins. It has a connecting rod for connecting the rectifying fins to each other, and the plurality of the rectifying fins are constant with respect to the air blowing direction by being connected by the connecting rod when the plurality of movable fins rotate. Discloses a register that rectifies the air flowing from the upstream to the surfaces of the plurality of movable fins downstream while maintaining the angle of.

According to the register of the present application, when a sidestream member for flowing a sidestream is provided in the fin, the mainstream air can be blown farther while suppressing the temperature change of the air and maintaining the temperature.

Hereinafter, a drawing of an embodiment in which the register of the present application is arranged in an instrument panel arranged in front of the passenger compartment of an automobile or the like and embodied in a register 10 that blows out conditioned air adjusted by an air conditioner into the passenger compartment. Will be explained with reference to. In the following description, as shown in FIGS. 1 to 3, the downstream side (that is, the passenger compartment side) in the ventilation direction of the register 10 of the present embodiment is set to the front, and the upstream side (that is, the air conditioner) in the ventilation direction. The side) will be described as the rear. Further, in the following description, the vertical direction and the horizontal direction will be defined and described by using the viewpoint of the user facing the register 10 in front of the register 10. Further, FIGS. 1 to 3 show a state in which the operation knob 20 is arranged at the initial position, the downstream fins 15 are aligned in the left-right direction, the upstream fins 17 are aligned in the vertical direction, and the blowing direction of the conditioned air is not changed (hereinafter, , May be called neutral state). More specifically, the neutral state of the downstream fin 15 is a state in which the upstream end and the downstream end of the downstream fin 15 in the conditioned air blowing direction 22 (see FIG. 5) are aligned with the blowing direction 22. Similarly, the neutral state of the upstream fin 17 is a state in which the upstream end and the downstream end of the upstream fin 17 in the conditioned air blowing direction 22 are aligned with the blowing direction 22.

(Structure of register 10)
The register 10 of the present embodiment is a device that blows out air-conditioned air adjusted by the air-conditioning device into the vehicle interior. As shown in FIGS. 1 to 4, the register 10 includes a retainer 11, a bezel 13, a downstream fin 15, a damper plate 16, an upstream fin 17, a rectifying member 19, and the like. The register 10 is formed, for example, by injection molding of a synthetic resin. The retainer 11 has a cylindrical shape extending in the front-rear direction. An air passage 21 (see FIG. 1) is formed inside the retainer 11. A duct (not shown) is connected to the rear end of the retainer 11 via an air passage 21. This duct is connected to an air conditioner (not shown) and blows air conditioning air supplied from the air conditioner to the retainer 11.

The bezel 13 is a member arranged on the front surface of the retainer 11. The bezel 13 is formed with an air outlet 31 long in the left-right direction, and is attached to a downstream opening 23 (see FIG. 4) which is an opening on the front side (downstream side) of the retainer 11. The bezel 13 is a frame-like member in which an air outlet 31 having a size matching the downstream opening 23 is formed and covers the peripheral edge of the downstream opening 23 from the front surface. The retainer 11 has a cylindrical shape that communicates with the air outlet 31 of the bezel 13, and blows conditioned air in the air blowing direction 22 (FIG. 5) that is in the direction toward the air outlet 31. In the following description, the terms "upstream side" and "downstream side" of the ventilation direction 22 may be used. The air passage 21 (retainer 11) has a substantially rectangular shape in which the cross section cut in a plane orthogonal to the air direction 22 is long in the left-right direction. Further, the bezel 13 is fixed to the retainer 11 by engaging the hole of the attached portion 32 with the protrusion of the mounting portion 24 of the retainer 11. The air outlet 31 blows out the conditioned air that is regulated by the air conditioner and flows through the air passage 21 toward the outside of the register 10 (user side such as an occupant). In the following description, the main flow of conditioned air that passes through the air passage 21 and is blown out from the air outlet 31 may be referred to as the main flow. Further, among the conditioned air flowing through the air passage 21, the conditioned air blown out from the side flow member 73 (see FIG. 1), which will be described later, may be referred to as a side flow. This sidestream disturbs the lateral vortices generated around the mainstream, suppresses the development of the lateral vortices, prolongs the reach of the mainstream, and suppresses the temperature change of the mainstream.

(Structure of downstream fin 15)
The downstream fin 15 is arranged inside the downstream opening 23 (the connecting portion between the bezel 13 and the retainer 11) of the retainer 11. The register 10 includes a plurality of (three in this embodiment) downstream fins 15. The three downstream fins 15 are arranged side by side in the vertical direction. The three downstream fins 15 have substantially the same structure except for the attachment structure of the operation knob 20 described later.

The downstream fin 15 has a predetermined width in the front-rear direction, is thin in the vertical direction, and has a long plate shape in the left-right direction. As shown in FIG. 6, fin shafts 41 are provided on the side surfaces of the downstream fins 15 in the left-right direction. The fin shaft 41 is provided at the front end of the downstream fin 15. Further, the retainer 11 has a pair of side walls 44 facing each other in the left-right direction. The pair of fin shafts 41 of the downstream fins 15 are rotatably held by bearing members 43 attached to each of the pair of side walls 44 facing each other in the left-right direction. As a result, each of the plurality of downstream fins 15 holds the fin shaft 41 by the retainer 11 and the bearing member 43, and is rotatable in the vertical direction with respect to the retainer 11. In addition, in FIG. 6, in order to make the drawing easy to understand, some members (damper plate 16, upstream fin 17, rectifying member 19, etc.) are shown not in cross section but in end face. In addition, some members such as the arm 63 are transparently illustrated.

A connecting shaft 45 is formed on the right end surface of the downstream fin 15. Of the three downstream fins 15, the connecting shaft 45 of any downstream fin 15 is connected to the connecting shaft 45 of the other downstream fins 15 by the connecting member 47, and the rotating force is transmitted by the connecting member 47. As a result, the plurality of downstream fins 15 rotate in the vertical direction in conjunction with each other, and change the blowing direction of the conditioned air blown out from the air outlet 31 in the vertical direction. A regulation shaft 49 is formed on the right end surface of the central downstream fin 15 in the vertical direction. The downstream fin 15 is restricted in the vertical rotation range to a certain range by inserting the regulation shaft 49 into the bearing member 43. The configuration of the downstream fin 15 described above is an example. For example, the downstream fin 15 does not have to include the regulation shaft 49.

An operation knob 20 is attached to the central downstream fin 15 in the vertical direction. The operation knob 20 is attached to the downstream fin 15 with the downstream fin 15 inserted, and is slidably attached in the left-right direction. The operation knob 20 is restricted in the sliding range in the left-right direction within a certain range by the regulation groove 15A (see FIG. 6) formed in the downstream fin 15. This slide range is the swing width of the upstream fin 17, which will be described later, in the left-right direction.

(Structure of damper plate 16)
As shown in FIGS. 3 and 5, a damper plate 16 is provided on the rear side (upstream side) of the upstream fin 17 and in the air passage 21 of the retainer 11. The damper plate 16 has a long plate shape in the left-right direction, and is held rotatably in the up-down direction by the retainer 11. The damper plate 16 is connected to the operation dial 18 provided on the bezel 13, and rotates in the vertical direction in accordance with the rotation of the operation dial 18. The damper plate 16 rotates to open and close the air passage 21, adjust the amount of conditioned air blown from the air outlet 31, and switch between supplying and stopping the supply of conditioned air.

(Structure of upstream fin 17 and rectifying member 19)
Next, the detailed configuration of the upstream fin 17 will be described. As shown in FIGS. 4 to 7, in the air passage 21 of the retainer 11, the upstream fin 17 is arranged on the upstream side of the downstream fin 15. The upstream fin 17 of the present embodiment has one first movable fin 51 and six second movable fins 53. The first and second movable fins 51 and 53 are arranged side by side with a predetermined interval provided along the left-right direction. The first movable fin 51 is arranged at the center in the left-right direction. The six second movable fins 53 are arranged three on the right side and three on the left side of the central first movable fin 51. In the following description, first, the first movable fin 51 will be described, and then the second movable fin 53 will be described. Further, when the first and second movable fins 51 and 53 are collectively referred to, they may be simply described as "movable fins".

As shown in FIGS. 5 and 7, the first movable fin 51 has a first main body portion 55 and a pair of first fin shafts 57. The first main body portion 55 has a predetermined thickness in the left-right direction, and has a substantially plate shape long in the vertical direction and the front-rear direction. A through hole 59 penetrating in the left-right direction is formed in the first main body portion 55. The through hole 59 has, for example, a shape in which a rectangle is extended in the vertical direction and one side on the rear side is projected to the rear side. In the first main body portion 55, a link shaft 61 is formed at the front end of the portion where the through hole 59 is formed. The link shaft 61 has a long cylindrical shape in the vertical direction. The operation knob 20 is provided with a pair of arms 63 (see FIG. 6) connected to the link shaft 61 of the first movable fin 51. The pair of arms 63 are bifurcated from the rear end of the operation knob 20 to the rear. The pair of arms 63 sandwich the link shaft 61 from both sides in the left-right direction, and connect the downstream fin 15 in the center in the vertical direction and the first movable fin 51 in the center in the left-right direction. As a result, the sliding movement of the operation knob 20 in the left-right direction is transmitted to the first movable fin 51. The first movable fin 51 suppresses interference with the arm 63 by inserting the arm 63 into the through hole 59 in the sliding movement of the operation knob 20. Stoppers 65 for restricting the movement of the arm 63 in the vertical direction are provided at both ends of the link shaft 61 in the vertical direction.

A pair of first fin shafts 57 are provided at both ends of the first main body portion 55 in the vertical direction. Bearing members 67 are attached to the pair of side walls 66 facing each other in the vertical direction of the retainer 11. Each of the pair of first fin shafts 57 is rotatably held by each of the bearing members 67. As a result, the first movable fin 51 is rotatably held by the retainer 11 via the bearing member 67, and is rotatable with the vertical direction as the axial direction. Each of the pair of bearing members 67 is formed with a recess 67A (see FIG. 4) for accommodating the stopper 65.

Further, a connecting plate 55A having a narrowed width in the vertical direction is formed at the rear end portion of the first main body portion 55 of the first movable fin 51. First connecting shafts 55B are formed at both ends of the connecting plate 55A in the vertical direction and at the rear ends. The first connecting shaft 55B is connected to a rectifying fin 81 of a rectifying member 19 described later.

Next, six second movable fins 53 will be described. The six second movable fins 53 of the present embodiment have the same configuration. The three second movable fins 53 on the left side and the three second movable fins 53 on the right side have a symmetrical structure. In the following description, the second movable fin 53 on the left side will be mainly described, and the description of the second movable fin 53 on the right side will be omitted as appropriate. Further, the description of the same contents as those of the first movable fin 51 described above will be omitted as appropriate.

As shown in FIGS. 7 to 15, the second movable fin 53 has a second main body portion 69 and a pair of second fin shafts 71. The second main body portion 69 has a predetermined thickness in the left-right direction, and has a substantially plate shape long in the vertical direction and the front-rear direction. A pair of second fin shafts 71 are provided at both ends of the second main body portion 69 in the vertical direction. Each of the pair of second fin shafts 71 is rotatably held by a pair of bearing members 67 provided on the retainer 11. As a result, the plurality of second movable fins 53 can rotate with the vertical direction as the axial direction. The upstream fin 17 rotates in the air passage 21 of the retainer 11 by holding the first fin shaft 57 of the first movable fin 51 and the second fin shaft 71 of the second movable fin 53 by a pair of bearing members 67. Then, the blowing direction of the conditioned air blown from the retainer 11 is changed to the left-right direction. The first movable fin 51 and the second movable fin 53 are arranged in a neutral state with the planes of the first main body portion 55 and the second main body portion 69 facing each other in the left-right direction and parallel to each other.

Further, a connecting plate 69A having a narrowed width in the vertical direction is formed at the rear end portion of the second main body portion 69 of the second movable fin 53. Second connecting shafts 69B are formed at both ends of the connecting plate 69A in the vertical direction and at the rear ends. The pair of second connecting shafts 69B are connected to the rectifying fins 81 of the rectifying member 19 described later.

Further, a pair of sidestream members 73 are formed in the second main body portion 69. The pair of sidestream members 73 are integrally formed with the second main body portion 69. The pair of sidestream members 73 are formed on one of the two surfaces of the second main body portion 69 facing each other in the left-right direction. The pair of sidestream members 73 are provided on the inner surface of the second main body portion 69 in the left-right direction, that is, the surface on the central first movable fin 51 side. More specifically, of the six first movable fins 51, three second movable fins 53 arranged on the left side with respect to the first movable fin 51 are paired on the right side surface 69C of the second main body portion 69. A sidestream member 73 is provided. Further, the three second movable fins 53 arranged on the right side with respect to the first movable fin 51 are provided with a side flow member 73 on the left side surface 69D of the second main body portion 69. Further, the pair of sidestream members 73 are provided at both ends of the second main body portion 69 in the vertical direction, that is, in the axial direction of the second movable fin 53.

Further, as shown in FIGS. 9 to 15, in the case of the second movable fin 53 on the left side, the side flow member 73 protrudes in the direction orthogonal to the right side surface 69C of the second main body portion 69 (in this case, the right direction). After that, it is formed on the end side of the second movable fin 53 and is curved outward with a predetermined curvature in the axial direction (in this case, the vertical direction) of the rotation axis of the second movable fin 53. For example, the upper sidestream member 73 protrudes to the right from the right side surface 69C and is curved upward. The sidestream member 73 is formed up to the same height as the upper end of the second main body 69 excluding the second fin shaft 71 in the axial direction (vertical direction in the embodiment) of the second movable fin 53. As shown in FIG. 16, at the position of the second fin shaft 71, the position of the upper end of the upper sidestream member 73 is a position slightly lower than the bearing member 67. In other words, the sidestream member 73 extends to a position where it forms a slight gap with the bearing member 67.

Further, as shown in FIG. 1, each of the pair of sidestream members 73 provided in one second movable fin 53 is a downstream fin in the axial direction (vertical direction in this embodiment) of the second movable fin 53. It is provided at a position where 15 is sandwiched between both sides in the vertical direction. In other words, each of the pair of sidestream members 73 is provided at a position deviated from the downstream fin 15 in the axial direction. As a result, it is possible to avoid a collision between the side flow blown out from the side flow member 73 and the downstream fins 15 and prevent the side flow from being disturbed by the downstream fins 15, and the side flow can be prevented while maintaining the shape of the vertical vortex. Can be blown out. Although the downstream fin 15 in the neutral state is shown in FIG. 1, the downstream fin 15 of the present embodiment is a straight line extending from the sidestream member 73 to the downstream side along the blowing direction 22 when swung in the vertical direction. It has a swing width that does not come into contact with. The downstream fin 15 and the sidestream member 73 may be at the same position in the axial direction. Further, when the downstream fin 15 is swung in the vertical direction, the downstream fin 15 is held by the retainer 11 with a swing width that is swung from the sidestream member 73 to a position where it overlaps with a straight line extending downstream along the blowing direction 22. You may.

Further, as shown in FIGS. 9 to 15, the cross section of the sidestream member 73 cut in a plane parallel to the vertical direction and the horizontal direction has a substantially arc shape of 1/4. The sidestream member 73 forms a groove along the front-rear direction with the right side surface 69C of the second main body portion 69. This groove has a shape in which a portion surrounded by the right side surface 69C and the side flow member 73 is cut out only on the outside in the axial direction of the second movable fin 53, and forms a side flow path 75. The downstream opening 73A, which is an opening on the downstream side of the sidestream member 73, is provided at a position flush with the front end of the second main body portion 69 of the second movable fin 53. More specifically, the downstream opening 73A is provided at the same position as the front end of the second main body portion 69 in the blowing direction 22 and at a position shifted in the left-right direction.

Further, the upstream opening 73B, which is an opening on the upstream side of the sidestream member 73, is provided at the position of the second fin shaft 71 of the second movable fin 53. More specifically, the upstream opening 73B is provided at the same position as the second fin shaft 71 in the blowing direction 22 and at a position deviated in the left-right direction. The second main body portion 69 has a tapered shape in which the width in the left-right direction is narrowed toward the front. Therefore, the sub-flow path 75 has a shape in which the flow path is slightly widened toward the front.

As shown in FIG. 7, the sub-flow path 75 allows a part of the conditioned air flowing through the retainer 11 to the air passage 21 to flow, and blows out from the air outlet 31 as a side flow 79. The side flow 79 flows, for example, as a vertical vortex that rotates about a direction along the side flow path 75. On the other hand, the lateral vortex generated around the main stream blown out from the air outlet 31 rotates about a direction orthogonal to the direction along the blowing direction 22 and the sub-flow path 75. Therefore, the side stream 79 blown out from the side flow path 75 disturbs the lateral vortex generated around the main stream and suppresses the development of the lateral vortex, thereby prolonging the reach of the main stream and causing the main stream to reach the main stream. It is possible to suppress temperature changes.

The shape of the second movable fin 53 of the present embodiment shown in FIGS. 9 to 15 is an example. For example, as shown in the sidestream member 101 of FIG. 17, the sidestream member may have a tubular shape. The sidestream member 101 is formed, for example, in the shape of a semicircular cylinder long in the blowing direction 22. The groove-shaped side flow member 73 shown in FIGS. 9 to 15 described above has a side flow 79 when the conditioned air is flowed into the side flow path 75, as compared with the tubular side flow member such as the side flow member 101. Pressure loss can be reduced. On the other hand, by forming the secondary flow path 75 into a tubular shape as in the side flow member 101 shown in FIG. 17, the conditioned air taken in from the upstream opening 73B (see FIG. 12) is blown forward as a side flow 79 without leaking. be able to. Further, the sidestream member 101 is not limited to a semicircular tubular shape, but may be a circular, elliptical, or polygonal (square, rectangular, or the like) tubular shape. Further, as shown by the side flow member 102 in FIG. 17, the side flow member may be bent inward in the axial direction. Further, as shown in FIG. 17, the two sidestream members 101 and 102 included in the one second movable fin 53 may have different shapes from each other. Further, one second movable fin 53 may be provided with only one sidestream member, or may be provided with three or more sidestream members. Further, one second movable fin 53 may include a plurality of types of sidestream members 73 having different shapes and lengths.

Further, as shown by the side flow member 103 in FIG. 18, the side flow member may be provided with an expansion portion 103A that expands the side flow path 75 at the upstream end portion in the ventilation direction 22. The expansion portion 103A has a shape in which the inner wall of the side flow member 103 is inclined outward from the downstream side to the upstream side to increase the flow path (inner diameter of the side flow member 103) of the side flow path 75. By expanding the sub-channel 75 (upstream opening 73B), more conditioned air can be taken into the sub-channel 75.

Further, the shape of the expansion portion 103A is not limited to the shape in which the inclined surface is formed on the inner wall as shown in FIG. For example, as shown in FIG. 19, the upstream end of the sidestream member 103 may be bent to the right side (direction away from the second main body portion 69) and further extended to the downstream side to form the expansion portion 103A. As a result, the upstream opening 73B can be further widened, and more conditioned air can be taken into the subchannel 75.

Further, as shown by the expansion portion 103A of FIG. 20, the expansion portion 103A may be formed by bending the upstream end of the sidestream member 103 to the right rear while bending the upstream end. In this case, the inner wall can be curved to form a smooth auxiliary flow path 75. Compared with the bent shape as shown in FIG. 19, the size of the vortex generated by the conditioned air flowing in from the upstream opening 73B and the decrease in the flow velocity due to the collision with the inner wall can be suppressed. That is, the conditioned air can flow into the sub-flow path 75 more smoothly.

Further, as shown in FIG. 20, the sidestream member 103 may have a length equal to or longer than that of the second movable fin 53 in the blowing direction 22. The sidestream member 103 shown in FIG. 20 is formed, for example, from the upstream end to the downstream end of the second movable fin 53 in the blowing direction 22. Further, the position of the downstream opening 73A of the sidestream member 73 may be a position on the upstream side of the downstream end of the second movable fin 53. Therefore, the shape, length, number, etc. of the sidestream members of the present disclosure can be changed as appropriate.

Next, the configuration of the rectifying member 19 will be described. As shown in FIGS. 5, 7, and 8, the rectifying member 19 is attached to the upstream side of the upstream fin 17 in the blowing direction 22. As shown in FIGS. 21 to 25, the rectifying member 19 has a plurality of rectifying fins 81 and a connecting rod 83. Each of the plurality of rectifying fins 81 is attached to each of the first movable fin 51 and the plurality of second movable fins 53, and is arranged side by side in the left-right direction.

The plurality of rectifying fins 81 have the same shape, and seven are provided corresponding to each of the first movable fin 51 and the six second movable fins 53. The rectifying fin 81 has a main body portion 85, an insertion portion 87, and a notch portion 89. The main body 85 has a predetermined thickness in the left-right direction, and has a substantially rectangular shape that is long in the up-down direction when viewed from one of the left-right directions. The main body 85 has a shape in which the width in the vertical direction is gradually shortened from the upstream side to the downstream side (see FIG. 24).

A convex surface 85A is formed at the upstream end of the main body 85 along the vertical direction. The convex surface 85A is formed by a curved surface protruding rearward with a predetermined curvature. As a result, by applying the conditioned air flowing from the upstream to the convex surface 85A of the curved surface, it is possible to suppress a decrease in the flow velocity and the generation of a vortex. Further, a concave surface 85B along the vertical direction is formed at the front end (downstream end) of the main body portion 85. The concave surface 85B is formed by a curved surface that is recessed rearward with a predetermined curvature.

As shown in FIG. 26, the thickness of the second main body portion 69 of the second movable fin 53 is the thickest at the position of the second fin shaft 71 in the blowing direction 22. The thickness of the second main body portion 69 becomes slightly thinner from the position of the second fin shaft 71 toward the front side or the rear side. The front end and the rear end of the second main body portion 69 are formed by a curved surface protruding outward in the ventilation direction 22. The concave surface 85B of the main body 85 of the rectifying fin 81 is recessed rearward in accordance with the protruding shape of the rear end of the second main body 69.

Further, as shown in FIGS. 21 to 25, the insertion portion 87 is formed at the upper end portion of the front end (concave surface 85B) of the main body portion 85. The insertion portion 87 has a cylindrical shape having a predetermined thickness in the vertical direction, and a through hole 87A penetrating in the vertical direction is formed. The first connecting shaft 55B (see FIG. 7) on the upper side of the first movable fin 51 or the second connecting shaft 69B on the upper side of the second movable fin 53 is inserted into the through hole 87A of each rectifying fin 81 (FIG. 7). 7). Each rectifying fin 81 is rotatably held by the first connecting shaft 55B and the second connecting shaft 69B by inserting the inserting portion 87 of the inserting portion 87 into the first connecting shaft 55B or the second connecting shaft 69B. ..

Further, the cutout portion 89 has a shape in which a front portion is cut out from a cylindrical plate having a predetermined thickness in the vertical direction. The cylindrical portion of the notch portion 89 is formed, for example, with the same diameter as the insertion portion 87 (see FIG. 25). The cutout portion 89 has a front portion cut out in a fan shape. The notch 89 of each rectifying fin 81 is fitted from behind with respect to the first connecting shaft 55B on the lower side of the first movable fin 51 or the second connecting shaft 69B on the lower side of the second movable fin 53. .. Each rectifying fin 81 is rotatably held by the first connecting shaft 55B or the second connecting shaft 69B by fitting the notch 89 into the first connecting shaft 55B or the second connecting shaft 69B.

Two connecting rods 83 are provided between two adjacent rectifying fins 81. A pair of connecting rods 83 provided between two adjacent rectifying fins 81 are provided at positions separated in the vertical direction to connect the two rectifying fins 81 to each other. Each connecting rod 83 has a predetermined width in the front-rear direction and is formed in a plate shape extending in the left-right direction. The plurality of rectifying fins 81 are connected to each other by a connecting rod 83. Each of the pair of connecting rods 83 is formed to have the same length in the left-right direction.

Further, the plurality of rectifying fins 81 are arranged so as to be spaced apart from each other (the length of the connecting rod 83) in the left-right direction. In the neutral state shown in FIG. 6, the plurality of rectifying fins 81 are arranged at the same intervals as the first and second movable fins 51 and 53 in the left-right direction. The arbitrary rectifying fin 81 and the movable fin connected to the rectifying fin 81 are arranged along the blowing direction 22. Therefore, the substantially plate-shaped rectifying fin 81 and the movable fin are arranged in a straight line.

The first and second movable fins 51 and 53 rotate about a rotation axis along the vertical direction as described above. The front end portions of the plurality of rectifying fins 81 are connected to the rear end portions of the first and second movable fins 51 and 53, respectively. As shown in FIG. 27, the rectifying member 19 is in the left-right direction and the front-rear direction according to the positions of the first connecting shaft 55B of the first movable fin 51 and the second connecting shaft 69B (see FIG. 7) of the second movable fin 53. Move to. Since the plurality of rectifying fins 81 of the rectifying member 19 are connected to each other by the connecting rod 83, they move in accordance with the direction of the upstream fin 17 while maintaining the state of being along the plane in the blowing direction 22. That is, the plurality of rectifying fins 81 maintain a neutral state (see FIG. 6) along the blowing direction 22 on both planes in the left-right direction even when the movable fins are swung in the left-right direction. In other words, the rectifying member 19 moves in the left-right direction and the front-rear direction while maintaining the direction with respect to the blowing direction 22 in the neutral state by connecting the plurality of rectifying fins 81 with the plurality of connecting rods 83.

The plurality of rectifying fins 81 rectify the air flowing from the upstream to the surfaces of the first and second movable fins 51 and 53 downstream while maintaining a constant angle with respect to the blowing direction 22. As shown by the arrows in FIG. 26, since the plurality of rectifying fins 81 have the convex surface 85A on the upstream side formed by a curved surface, the conditioned air coming from the upstream can flow along the convex surface 85A. The conditioned air rectified downstream by the rectifying fins 81 is separated from the surface (right side 69C and left side 69D) of the second movable fin 53 that is aligned with the rectifying fins 81 and the rectifying fins 81. The flow is suppressed (in the direction). The conditioned air flows along the right side surface 69C and the left side surface 69D of the second main body portion 69, and flows into the side flow member 73. As a result, the conditioned air can be stably supplied into the sub-flow path 75, and the effect of the side flow 79 (see FIG. 7) such as suppression of the lateral vortex by the vertical vortex can be further enhanced.

Further, as shown in FIG. 28, the rectifying fin 81 maintains the direction with respect to the blowing direction 22 even when the second movable fin 53 is swung in the left-right direction. As shown in FIG. 29, for example, in a configuration without a rectifying member 19 (rectifying fin 81), when the second movable fin 53 is swung to the left, the second movable fin 53 is predetermined with respect to the blowing direction 22. Since it is tilted at an angle, the conditioned air coming from the upstream flows in the direction of peeling from the downstream side (right side surface 69C) of the second movable fin 53. The flow velocity may decrease, vortices 95 may be generated due to peeling, and wind noise may increase. On the other hand, as shown in FIG. 28, in the register 10 of the present embodiment, the orientation of the rectifying fin 81 is maintained even when the second movable fin 53 is shaken, and the second movable fin of the conditioned air is maintained by the rectifying fin 81. The peeling from 53 can be suppressed. The conditioned air flowing from the upstream flows along the convex surface 85A, and is rectified so as to flow along the right side surface 69C and the left side surface 69D of the second main body portion 69. Therefore, the effect of the side flow 79 can be further enhanced even when the second movable fin 53 is swung in the left-right direction.

Further, in the upstream fin 17, the first and second movable fins 51 and 53 are connected to each other by a rectifying member 19. Therefore, when any of the first and second movable fins 51 and 53 rotates, the rotating force is transmitted to the other movable fins by the rectifying member 19. Therefore, the first and second movable fins 51 and 53 rotate in the left-right direction in conjunction with each other around the rotation axis along the vertical direction. When the operation knob 20 is slid and moved in the left-right direction, the first movable fin 51 at the center rotates in the left-right direction in accordance with the movement of the operation knob 20. The plurality of second movable fins 53 rotate in the left-right direction in conjunction with the first movable fins 51. Thereby, by operating the operation knob 20, the blowing direction of the conditioned air blown from the retainer 11 can be changed to the left-right direction.

Further, as shown in FIGS. 5 and 8, bearing members 67 are attached to a pair of side walls 66 facing each other in the vertical direction of the retainer 11 of the present embodiment. The pair of bearing members 67 are formed in a thin plate shape and form a part of the air passage 21. The pair of bearing members 67 are inclined in the vertical direction toward each other from the upstream side to the downstream side. The flow path width 91 of the air passage 21 in the vertical direction gradually becomes shorter from the upstream to the downstream at the position where the pair of bearing members 67 are attached. That is, the flow path of the air passage 21 is narrowed. As a result, it is possible to generate a contraction in the flow of the conditioned air (squeeze the flow) and increase the flow velocity of the conditioned air. Further, in the conditioned air flowing between the pair of bearing members 67, the velocity difference between the velocity on the center side of the air passage 21 and the velocity on the bearing member 67 (side wall 66) side can be reduced.

Further, the rectifying fin 81 of the present embodiment is arranged at a position sandwiched between a pair of bearing members 67 in the vertical direction and at a position on the downstream side of a portion where the flow path width 91 is narrowed by the pair of bearing members 67. There is. In other words, the rectifying fins 81 are arranged at positions where the flow velocity is increased by the pair of bearing members 67. As a result, the conditioned air having a higher flow velocity can be rectified by the rectifying fins 81 and guided into the sidestream member 73 of the second movable fins 53. The effect of the side flow 79 such as suppression of the horizontal vortex by the vertical vortex can be further enhanced.

Further, as shown in FIG. 1, each of the pair of sidestream members 73 provided in one second movable fin 53 is positioned at different positions of the pair of connecting rods 83 in the axial direction of the second movable fin 53. It is provided in. Each of the pair of sidestream members 73 is arranged outside each of the pair of connecting rods 83 in the axial direction. As a result, the flow of the wind flowing into the sidestream member 73 can be suppressed from being disturbed by the connecting rod 83 on the upstream side, and the sidestream 79 can be blown out while maintaining the shape of the vertical vortex.

The configuration of the upstream fin 17 and the rectifying member 19 of the present embodiment described above is an example. For example, the number of rectifying fins 81 may be larger than the number of the first movable fins 51 and the second movable fins 53, or at least better. That is, it is not necessary to provide the rectifying fins 81 corresponding to all the first and second movable fins 51 and 53. Further, one connecting rod 83 may be provided between the two rectifying fins 81, or three or more connecting rods 83 may be provided. Further, the connecting rod 83 may connect the rectifying fins 81 having one or more rectifying fins 81 sandwiched between them instead of the adjacent rectifying fins 81. Further, the connecting rod 83 may have a cylindrical shape, for example, instead of a plate shape.

Next, the measurement result when the conditioned air is blown out by the register 10 of the present embodiment will be described. FIG. 30 graphically shows the relationship between the ultimate temperature T and the directivity angle θ. The vertical axis of the graph of FIG. 30 indicates the ultimate temperature T (° C.). In the measurement, for example, the temperature of the cold air blown out from the register 10 and the temperature of the room in which the register 10 was arranged were kept constant. The measurement position P1 is set to a position at a constant distance L from the register 10. The reached temperature T is a value obtained by measuring the temperature of the conditioned air (cold air) that has reached the measurement position P1.

The horizontal axis of the graph indicates the directivity angle θ (degrees). The directivity angle θ is, for example, the angle of the conditioned air actually blown out from the register 10. For example, when the neutral state is set to “0 degree” and the upstream fin 17 is swung to the left by a predetermined angle, the directivity angle θ deviates from the angle of the upstream fin 17 (hereinafter referred to as a set angle). In the measurement, the set angles of the downstream fins 15 were adjusted so that the same directivity angle θ was obtained, and the graphs GR1 to GR4 (each configuration) were measured. In the measurement, for example, the upstream fin 17 was swung to the left and the set angle was changed to the left (the left directivity angle was changed). For example, the directivity angle θ was set to 0 degree, 10 degree, 16 degree, and 23 degree as the left directivity angle, and the measurement was performed. As shown on the right side of the graph, the measurement position P1 is located at a position separated by a certain distance L along the directivity angle θ from the center position P2 in the left-right direction of the register 10 in accordance with the change of the directivity angle θ. be.

First, the graph GR1 is a case where the measurement is performed in a configuration that does not include all the mechanisms of contraction, sideflow, and rectification. Specifically, the configuration of the register 10 in which the graph GR1 is measured is such that the pair of bearing members 67 in the above embodiment is not inclined and the flow path of the air passage 21 is not narrowed down, and all the second movable fins 53 are configured. The configuration is such that the sidestream member 73 is not provided and the rectifying member 19 is not provided. That is, it is a configuration that does not obtain all the effects of contraction, sideflow, and rectification. As shown in the graph GR1, in the configuration without anything, the ultimate temperature T rises at 23 degrees (= directivity angle θ) after falling once when the upstream fin 17 is swung to the left to increase the directivity angle θ. doing.

Further, the graph GR2 is a case where the measurement is performed in a configuration provided with a contraction mechanism. Specifically, as in the above embodiment, the pair of bearing members 67 are tilted to generate a contraction, and the side flow member 73 and the rectifying member 19 are not provided. As shown in the graph GR2, in the configuration including only the contraction mechanism, when the directivity angle θ is 0 degrees, the ultimate temperature T is slightly higher than the graph GR1. On the other hand, when the directivity angle θ is increased, the ultimate temperature T is lower than that of the graph GR1. It is considered that this is because the increase in the ultimate temperature T of the cold air could be suppressed by increasing the flow velocity by the action of contraction.

Further, the graph GR3 is a case where the measurement is performed in a configuration provided with a mechanism of contraction and side flow. Specifically, as in the above embodiment, the pair of bearing members 67 are inclined, and the sidestream members 73 are provided on all the second movable fins 53, and the rectifying member 19 is not provided. As shown in the graph GR3, the ultimate temperature T when the directivity angle θ is 0 degrees can be significantly lowered as compared with the graphs GR1 and GR2 by the action of the contraction flow and the side flow. On the other hand, when the directivity angle θ is increased, the ultimate temperature T exceeds the graphs GR1 and GR2 at the time points of 10 degrees and 16 degrees.

Then, the graph GR4 is a case where the measurement is performed by the register 10 of the present embodiment. As shown in the graph GR4, in the register 10 of the present embodiment, the ultimate temperature T when the directivity angle θ is 0 degrees can be further lowered as compared with the graph GR3. When the directivity angle θ of the graph GR4 was 0 degrees, it was confirmed that the ultimate temperature T was about 2 degrees lower than that of the graph GR1 (configuration without anything). Further, in the register 10 (graph GR4) of the present embodiment, even when the directivity angle θ is increased, it is possible to suppress an increase in the ultimate temperature T as compared with other configurations. In other words, the temperature rise of the cold air blown out from the register 10 can be suppressed, and the cold air can be blown farther. In the register 10 of the present embodiment, as shown in FIG. 30, a particularly remarkable improvement effect of air conditioning performance can be obtained in the range of the directivity angle θ from 0 degrees to 16.

Incidentally, in the above embodiment, the second movable fin 53 is an example of a movable fin. The bearing member 67 is an example of a contraction member. The right side surface 69C and the left side surface 69D are examples of surfaces. The second fin shaft 71 is an example of the fin shaft. The downstream opening 73A is an example of an opening.

As described above, according to the above-described embodiment, the following effects are obtained.
(1) The register 10 of the present embodiment is provided rotatably in a retainer 11 having an air passage 21 for blowing conditioned air in the air blowing direction 22 and an air passage 21 of the retainer 11, and blows out conditioned air blown out from the retainer 11. A plurality of second movable fins 53 that change directions and a rectifying member 19 attached to the upstream side of the plurality of second movable fins 53 in the blowing direction 22 are provided. Of the plurality of second movable fins 53, at least one of the second movable fins 53 is provided with a secondary flow path 75 through which a part of the conditioned air flowing through the air passage 21 flows, and a side flow that blows out the side flow from the secondary flow path 75. It has a member 73. The rectifying member 19 has a plurality of rectifying fins 81 attached to each of the plurality of second movable fins 53 and arranged side by side in one direction, and a connecting rod 83 for connecting the plurality of rectifying fins 81 to each other. When the plurality of second movable fins 53 rotate, the plurality of rectifying fins 81 are connected by the connecting rod 83, so that the air conditioning flowed from the upstream while maintaining a constant angle with respect to the blowing direction 22. The air is rectified to the surfaces (right side surface 69C, left side surface 69D) of the plurality of second movable fins 53 downstream.

According to this, the rectifying fin 81 is provided on the upstream side of the second movable fin 53 having the side flow member 73, and the conditioned air flowing from the upstream is rectified to the surface of the second movable fin 53. By rectifying the conditioned air with the rectifying fin 81, it is possible to prevent the conditioned air flowing from the upstream from hitting the upstream end of the second movable fin 53 and flowing in the direction of peeling from the second movable fin 53 (FIG. 28, FIG. FIG. 29). In particular, when the second movable fin 53 is rotated, even if the second movable fin 53 is tilted with respect to the blowing direction 22 by connecting with the connecting rod 83 and maintaining the rectifying fin 81 at a constant angle. The conditioned air flowing from the upstream can flow along the second movable fin 53. As a result, the conditioned air can be stably collected in the sub-flow path 75 of the side flow member 73 provided in the second movable fin 53. As a result, due to the effect of the side flow 79 (see FIG. 7) blown out from the side flow member 73, the mainstream conditioned air can be blown farther while suppressing the temperature change of the mainstream conditioned air and maintaining the temperature. can.

(2) Further, each of the plurality of second movable fins 53 is formed in a plate shape. The sidestream member 73 is provided on each of the plurality of second movable fins 53, and is a surface (right side surface) inside the second movable fins 53 in the direction in which the plurality of second movable fins 53 are arranged (left-right direction in the embodiment). It is provided on 69C or 69D on the left side). According to this, the conditioned air whose flow velocity is increased by reducing the diameter of the flow path by the adjacent second movable fins 53 can be blown out together with the air of the side flow 79. Further, by providing the side flow member 73 inside, when a plurality of second movable fins 53 are rotated, the side flow member 73 provided on the outermost second movable fin 53 and the retainer 11 in the left-right direction Interference with the side wall 44 can be suppressed. The rotation range (swing width) of the second movable fin 53 in the left-right direction can be further increased.

(3) Further, the register 10 includes downstream fins 15 provided on the downstream side of the plurality of second movable fins 53 and rotatably provided in the air passage 21 of the retainer 11. The downstream fin 15 is provided at a position deviated from the downstream opening 73A on the downstream side of the side flow path 75 of the side flow member 73 in the axial direction (vertical direction) of the second fin shaft 71 of the second movable fin 53. According to this, in addition to the second movable fin 53, the downstream fin 15 can change the blowing direction of the conditioned air. Further, the downstream fin 15 is arranged at a position deviated from the downstream opening 73A of the auxiliary flow path 75 in the axial direction of the second movable fin 53. It is possible to prevent the flow of the side flow 79 of the vertical vortex blown out from the downstream opening 73A from hitting the downstream fin 15 and being disturbed. In other words, even when the downstream fins 15 are arranged, the effect of the side stream 79 can be maintained, and the main stream can be blown farther while maintaining the temperature.

(4) Further, the second movable fin 53 has a pair of sidestream members 73. Each of the pair of sidestream members 73 is arranged at a position sandwiching the downstream fin 15 in the axial direction (vertical direction) of the second movable fin 53. According to this, by providing two sidestream members 73 in one second movable fin 53, it is possible to suppress the generation and development of a lateral vortex with the mainstream sandwiched between the two sidestreams 79. Further, by providing the two sidestream members 73 at positions deviated from the downstream fins 15, the lateral vortices can be suppressed more effectively by the two sidestream members 73.

(5) Further, the side flow member 103 may be provided with an expansion portion 103A that expands the sub flow path 75 at the upstream end portion in the ventilation direction 22 (FIGS. 18 to 20). According to this, more air-conditioned air rectified by the rectifying fins 81 and along the second movable fins 53 can be taken into the sub-channel 75 by expanding the sub-channel 75.

(6) Further, the register 10 is arranged inside the retainer 11 and includes a bearing member 67 that narrows the flow path of the air passage 21. The plurality of rectifying fins 81 are arranged inside the air passage 21 whose flow path is narrowed by the bearing member 67 (FIGS. 5 and 8). According to this, while increasing the flow velocity of the conditioned air flowing in the air passage 21 by the bearing member 67, the rectifying air can be rectified by the rectifying fins 81 and the air can be taken into the sub flow path 75. Due to the synergistic effect of the acceleration of the flow velocity by the bearing member 67 and the rectifying action of the rectifying fin 81, the mainstream conditioned air can be blown farther while maintaining the temperature.

(7) Further, the sidestream member 73 is on the vertical end side of the second movable fin 53 after projecting in a direction orthogonal to the plane of the second movable fin 53, and is the second movable fin 53. The two fin shafts 71 are formed to be curved outward with a predetermined curvature in the axial direction, and the auxiliary flow path 75 is formed by a groove notched outside in the axial direction. According to this, by rounding the corners of the side flow member 73 and forming the side flow member 73 into a curved shape, the side flow 79 can be easily rotated in the direction of the vertical vortex (in the circumferential direction of the side flow member 73). .. Further, the pressure loss of the side flow 79 flowing through the side flow path 75 can be reduced. Further, by forming the side flow member 73 into a groove shape, the pressure loss of the side flow 79 flowing through the side flow path 75 can be further reduced. As a result, the effect of suppressing the lateral vortex by the side flow 79 can be further enhanced.

It should be noted that the content of the present application is not limited to the above-described embodiment, and it goes without saying that various improvements and modifications can be made without departing from the gist of the present application.
For example, the air blown out by the register of the present application is not limited to the conditioned air adjusted by the air conditioner, and may be outside air or the like.
Further, the register according to the present application is not limited to the register 10 mounted on the vehicle, and a register used in various air conditioning equipment such as air conditioning of a building can be adopted. That is, the register of the present application can be widely applied not only to automobiles but also to automobiles as long as it changes the direction of the blown air.
In the above embodiment, the six second movable fins 53 all include the sidestream member 73, but the present invention is not limited to this. The number of the second movable fins 53 including the sidestream member 73 may be one, or may be a plurality of second movable fins 53 other than six.

Further, the shape and number of the members included in the register 10 of the above embodiment are examples.
For example, the register 10 may be configured to include only the upstream fins 17 without the downstream fins 15. Further, the second movable fin 53 may be configured to rotate in the vertical direction. That is, the second movable fin 53 may change the blowing direction of the conditioned air in the vertical direction. Further, the register 10 may be configured to include only one downstream fin 15.
Further, the number of fins such as the second movable fin 53 and the rectifying fin 81 may be appropriately changed. For example, the number of rectifying fins 81 is at least better than the number of second movable fins 53.
Further, the sidestream member 73 may be provided outside the second movable fin 53. Further, sidestream members 73 may be provided on both sides of the second movable fin 53 in the left-right direction.
Further, the downstream fin 15 may be arranged at a position on the downstream side of the downstream opening 73A.
Further, the bearing member 67 may have a configuration in which the flow path of the air passage 21 is not narrowed (contracted). Further, only one of the pair of bearing members 67 may be contracted. Further, the bearing members 67 may be provided on both sides in the left-right direction.

Next, the technical idea derived from the contents of the above embodiment will be described.
(Appendix 1)
The sidestream member
The sub-flow path of the flow path shorter than the length of the at least one movable fin in the air blowing direction is provided.
According to this, by making the sub-channel shorter than the length of the movable fin, it is possible to make it easier for the air flowing from the upstream to flow into the sub-channel. The effect of sidestream can be enhanced.

(Appendix 2)

It is provided at the same position as the rotation axis of one movable fin in the blowing direction.
According to this, the sidestream member is the length from the downstream end of the movable fin to the position of the rotating shaft. The length of the side flow member can be reduced to about half that of the movable fin, and air can be easily flowed into the side flow path.

(Appendix 3)
The connecting rod
It is provided at a position deviated from the opening on the upstream side of the side flow member in the side flow path in the axial direction of the rotation axis of the movable fin.
According to this, by shifting the opening on the upstream side of the sub-channel and the position of the connecting rod, it is possible to prevent the flow of air flowing into the sub-channel from being obstructed by the connecting rod. Air can easily flow into the secondary flow path.
