Description

  The present invention relates to an air outlet adjustment register used for an air outlet of an air conditioner such as an automobile, and more particularly to a register having an elongated air outlet that is long in the longitudinal direction and short in the lateral direction.

  As a register for air blowing adjustment used for air outlets for air conditioning of automobiles, etc., a laterally movable louver and a longitudinally movable louver are arranged in front and rear in a bezel or retainer that forms a ventilation path, and provided on the bezel A resistor that adjusts the air blowing direction by changing the angle of each fin of the laterally movable louver and the longitudinally movable louver when air is blown from the air outlet is generally used in air conditioning of automobiles.

  As this type of register, a register having an elongated air outlet that is long in the longitudinal direction and short in the lateral direction, and provided with a few movable fins on the inside of the air outlet is mainly designed and It may be produced from design demand. Such a register is known, for example, from Patent Document 1 below.

JP 2002-103954 A JP 2009-160981 A

  Since the register having the elongated air outlet has an elongated shape that is long in the longitudinal direction and short in the lateral direction, the number of movable fins that are long in the longitudinal direction is inevitably about 1 to 3. Since the number of the air blower outlets is reduced and the short direction of the air outlet is narrowed, and the front movable fin is disposed at the narrowed air outlet, the pressure loss due to the front movable fin during blowing is likely to increase.

  Further, in such a register having a long and narrow air outlet in the longitudinal direction, when the number of fins along the longitudinal direction is as small as, for example, about one or two, the direction of the fin is changed to the short side of the air outlet. Even if the direction is changed up and down or left and right along the direction, it is difficult to sufficiently change the direction of the wind in that direction, and the directivity of the wind tends to deteriorate.

  Therefore, according to Patent Document 2, the present applicant arranges one front movable fin on the inner side of the air outlet in a register provided with an elongated air outlet that is long in the longitudinal direction and short in the lateral direction. We have proposed a register designed to reduce the pressure loss during blowing and to improve the directivity of the wind.

  However, in this register, one front movable fin is arranged along the longitudinal direction inside the air outlet, and the front movable fin is rotated around a support shaft parallel to the longitudinal direction, Since the wind direction is adjusted, there is a limit to reducing the pressure loss during blowing and improving the directivity of the wind with this front movable fin, and further improvement has been desired.

  The present invention has been made in view of the above points, and has a slender air outlet having a good design, improves directivity when adjusting the wind direction, and can reduce pressure loss during blowing. The purpose is to provide.

  In order to achieve the above object, the register of the present invention has a case-like register body in which a ventilation path connected to a ventilation duct through an air inlet is provided, and a longitudinal direction is provided at a front portion of the register body. A pair of film-like flexible membrane members that are parallel to the longitudinal direction of the register body and bendable in a register provided with a long and short air outlet in the short direction. An outlet and the air inlet are connected to each other, and a flexible ventilation path is formed inside the pair of flexible membrane members so as to be able to bend. A wind direction adjusting mechanism for deflecting the flexible air passage in the short direction of the air outlet, curving the flexible ventilation path in the short direction, and changing the direction of the wind blown from the air outlet to the short direction; The flexible air passage is curved by the wind direction adjusting mechanism, and the air outlet And wherein changing the blowing direction of wind blown et.

  According to the register of the present invention, the pair of flexible membrane members are bent by the wind direction adjusting mechanism, the flexible ventilation path is bent, and the blowing direction of the wind is changed to the short direction of the air outlet. The air blowing direction in the short direction of the air outlet can be changed smoothly, and there are no movable fins that tend to cause pressure loss inside the air passage or the air air outlet, so that the pressure loss during air blowing can be greatly reduced. .

  Further, since there are no movable fins in the air outlet, the air outlet can be designed to be elongated and simple, and the design of the register front surface can be improved. Furthermore, since the flexible ventilation path by a pair of flexible membrane members can be smoothly curved in the short direction and the blowing direction of the wind can be changed, there is little separation of the blowing air flow, and the blowing direction with a sufficient air volume The air can be blown while smoothly changing.

  Here, the pair of flexible membrane members are supported so that both end portions on the upstream side are slidable in the ventilation direction in the register body, and the blowing direction is changed by curving the flexible membrane members. At this time, it is preferable that both end portions of the flexible membrane member are slid from the upstream side to the downstream side.

  A support plate is attached to each downstream end of the pair of flexible membrane members along the longitudinal direction of the air outlet, and both downstream ends of the pair of support plates are downstream. The shaft is rotatably supported by a support shaft parallel to the longitudinal direction, a connecting shaft is provided at a position deviated from the supporting shaft, and the pair of flexible membranes are swung by swinging the connecting shaft. The member can be bent and the flexible ventilation path can be bent.

  Alternatively, a long support rod is attached to each downstream end of the pair of flexible membrane members along the longitudinal direction of the air outlet, and both side ends of the support rod are rotated. It is possible to support the pair of support rods, and the pair of support rods can be rotated in the same direction to bend the flexible ventilation path.

  Further, the wind direction adjusting mechanism pivotally supports the rotating member on both sides of the register body, and links the displacement position of the rotating member to the displaced connecting shaft of the support plate. By rotating the pivoting member to swing the displaced connecting shaft of the support plate, the pair of support plates are rotated about the support shaft, and the flexible ventilation path Can be configured to bend.

  Here, a swinging link is connected to the connecting shafts on both sides of the pair of support plates, and the connecting shaft provided at the center of the swinging link is engaged with a long hole provided by being displaced from the rotating member. Thus, the rotating member can be configured to be linked to the connecting shaft of the support plate.

  According to the register of the present invention, it is possible to provide an elongated air outlet having a good design on the front surface, improve the directivity when adjusting the wind direction, and reduce the pressure loss during blowing.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1 to FIG. 7, this register has a case-shaped register body 1 and is provided with a flexible ventilation path 2 inside. An outlet 4 is provided. As shown in FIG. 1, the air outlet 4 at the front of the register is formed in a flat and elongated slit shape, and is a horizontally long rectangle that is long in the longitudinal direction (horizontal direction in the horizontal direction) and short in the lateral direction (vertical direction). . Here, the L direction shown in FIG. 1 is the longitudinal direction, and the S direction is the short direction.

  The case-shaped register body 1 is configured so that an upper body 1a that forms an upper outer shell and a lower body 1b that forms a lower outer shell are aligned on a horizontal plane to form a ventilation path inside.

Yes. Further, a cover-like rear main body 1c is attached to the rear portion of the register main body 1 so as to communicate with the inside thereof, and an air inlet 3 is formed on the back side of the rear main body 1c. The air inlet 3 is connected to a ventilation duct (not shown) for blowing.

  As shown in FIG. 6, a pair of film-like flexible membrane members 21 and 22 are formed between the air outlet 4 and the air inlet 3 so as to be able to bend up and down along the horizontal longitudinal direction in the register main body 1. Are arranged so as to connect. The flexible membrane members 21 and 22 are made of a flexible synthetic resin film (synthetic resin sheet) having a thickness of about 0.1 to 0.2 mm, for example. The flexible membrane members 21 and 22 are elastically deformed from a plate shape to a curved shape when subjected to a load in the bending direction, and have shape retaining properties for retaining those shapes. When the support plates 25 and 26 attached to the downstream end portions of the flexible membrane members 21 and 22 are subjected to a bending load when they rotate, the flexible membrane members 21 and 22 are elastically deformed into a curved shape. When the bending load disappears, it returns to a flat shape.

  The pair of film-like flexible membrane members 21 and 22 are formed in a rectangular shape, and support plates 25 and 26 are fixed to the downstream ends thereof as shown in FIGS. Further, slide members 23 and 24 are fixed to the upstream end portions of the flexible membrane members 21 and 22. The support plates 25 and 26 and the slide members 23 and 24 are formed to have substantially the same width as the flexible membrane members 21 and 22, and support shafts 25 a and 26 a protrude on both sides of the downstream end portion of the support plates 25 and 26. Connection shafts 25b and 26b are provided on both sides of the upstream end portions of the support plates 25 and 26, respectively.

  The support shafts 25a and 26a of the support plates 25 and 26 are rotatably supported on both sides of the register body 1, and the support plates 25 and 26 on both sides are supported by the support shafts 25a and 26a as shown in FIGS. In this structure, the connecting shafts 25b and 26b are swung up and down. As shown in FIG. 7, the support shafts 25 a and 26 a of the support plates 25 and 26 on both sides are supported by the bearing bushes 15 and 16 so as to be rotatable without rattling. As will be described later, swing links 13 and 14 are swingably connected to both sides of the connection shafts 25b and 26b on the upstream side of the support plates 25 and 26, respectively.

  On the other hand, the slide members 23 and 24 fixed to the upstream end portions of the pair of flexible membrane members 21 and 22 are formed in a narrow plate shape as shown in FIG. Two guide shafts 23a and 24a are projected in parallel from both end portions of 23 and 24, respectively. As shown in FIGS. 6 and 7, these guide shafts 23a and 24a are engaged with guide grooves 5 and 5 provided horizontally on the inner walls on both sides of the register body 1 in parallel with the ventilation direction, as shown in FIGS. Thus, when the flexible membrane members 21 and 22 are curved, the guide shafts 23a and 24a are slidably supported on the downstream side so as to allow the bending.

  As shown in FIG. 6, the pair of flexible membrane members 21 and 22 configured as described above are arranged in the horizontal direction in the ventilation path in the register body 1 when the support plates 25 and 26 are in the horizontal state. A flexible ventilation path 2 is formed between the flexible membrane member 21 and the flexible membrane member 22 that can be kept in parallel and can be blown out straight. Then, as shown in FIGS. 8 and 9, the pair of support plates 25 and 26 rotate so as to swing the connecting shafts 25b and 26b up and down around the support shafts 25a and 26a at the downstream end thereof. Then, the pair of flexible membrane members 21 and 22 are similarly curved in a mountain or valley shape, and the flexible ventilation path 2 therebetween is similarly curved.

  The pair of support plates 25 and 26 are pivoted about the support shafts 25a and 26a so as to swing the connecting shafts 25b and 26b up and down, and a pair of flexible membrane members 21 and 22; And in order to curve the flexible ventilation path 2 between them and to change a wind direction into a transversal direction (up-down direction), as shown in FIG. 4, the wind direction adjustment mechanism 10 is provided.

  As described above, the swing links 13 and 14 are swingably connected to the connecting shafts 25b and 26b of the support plates 25 and 26 on both sides thereof. , 14 are pivotally supported on both sides of the register main body 1 so as to swing up and down, and the rotating members 11, 12 are rotated at a predetermined angle by a motor 16 shown in FIG. This structure is rotationally driven within the range.

  As shown in FIG. 7, the rocking links 13 and 14 are provided with connecting shafts 13a and 14a projecting outward at the center. The rotating members 11 and 12 are formed in a plate shape having an extending portion extending to one of the semicircular portions, shaft holes 11c and 12c are formed at the center of the semicircular portion, and projecting from both sides of the register main body 1 The shaft holes 11c and 12c are fitted to the shaft portions 1d and 1d (FIGS. 4 and 7) so as to be pivotally supported.

  The outer peripheral parts of the semicircular parts of the rotating members 11 and 12 on both sides are formed as gear parts 11a and 12a, and the gear parts 11a and 12a mesh with a pinion 17 fixed to the rotating shaft of the motor 16 (FIG. 4). The rotating members 11 and 12 are rotated by the motor 16 within a predetermined angle range. The motor 16 and the pinion 17 are provided on both sides of the register body 1 and rotate the rotating members 11 and 12 on both sides in the same direction by the same angle to adjust the up and down blowing direction of the air blow.

  Further, as shown in FIGS. 4 and 7, elongated portions 11b and 12b are provided in the extending portions of the rotating members 11 and 12, and the swing links 13 and 14 are connected to the elongated holes 11b and 12b. The shafts 13a and 14a are engaged. As a result, as shown in FIG. 4, when the motor 16 of the wind direction adjusting mechanism 10 rotates, the rotating members 11 and 12 on both sides similarly rotate upward or downward via the pinion 17. The swing links 13 and 14 having the connecting shafts 13a and 14a engaged with the twelve long holes 11b and 12b similarly swing up or down. As a result, as shown in FIGS. 8 and 9, the pair of support plates 25 and 26 rotate about the downstream support shafts 25a and 26a. At this time, the pair of flexible membrane members 21 and 22 are rotated. Is curved in a mountain or valley shape, and the flexible ventilation path 2 therebetween is curved.

  On the other hand, a rear movable louver 7 having a plurality of vertical fins 7a arranged in parallel is disposed in the rear main body 1c provided at the rear of the register main body 1, and the vertical fins 7a of the rear movable louver 7 are rotated left and right. By doing so, the air flow is adjusted in the left-right direction. Each vertical fin 7a of the rear movable louver 7 is attached to the rear main body 1c with a support shaft 7b projecting from the upper and lower sides thereof, and is attached to the rear main body 1c at a constant interval, as shown in FIG. A single link bar 7d is connected to the connecting shaft 7c provided at the position of displacement below each vertical fin 7a.

  Further, a connecting shaft 8 is connected to a support shaft 7b below one vertical fin 7a, and a gear 8a is attached to the connecting shaft 8, and a pinion 9a of a motor 9 for driving the vertical fin is engaged with the gear 8a. To do. Thereby, by the rotational drive of the motor 9, the vertical fin 7a of the rear movable louver 7 rotates to the left and right about the support shaft 7b, and the blowing direction is changed to the left and right direction.

  In addition, it can replace with the motor 9 which drives the rear movable louver 7, and can provide a manual operation knob and can change the direction of the vertical fin 7a of the rear movable louver 7 by operation of an operation knob. Further, instead of the motor 16 that drives the wind direction adjusting mechanism 10, a manual operation knob may be provided on a part of the front surface of the register body 1. By operating the operation knob, the pair of support plates 25 and 26 are provided. The structure can be configured such that the wind blowing direction is changed up and down by rotating around the support shafts 25a and 26a.

  The register having the above-described configuration is attached to an instrument panel or a dashboard portion in an automobile with the air introduction port 3 connected to a ventilation duct (not shown). The resistor air outlet 4 is exposed on the front of the instrument panel or dashboard, but there are no visually conspicuous movable fins inside the air outlet 4 and the air outlet 4 is designed to be very long and simple. , The design of the front is innovative and excellent.

  As shown in FIG. 6, when the pair of support plates 25 and 26 hold the horizontal state in parallel, the pair of flexible membrane members 21 and 22 are also in the horizontal parallel (flat) state and flexible. The flexible ventilation path 2 between the membrane member 21 and the flexible membrane member 22 is connected straight and horizontally to the air outlet 4, and when air is blown in this state, the air flow is as shown in FIG. From the air inlet 3, the air travels straight through the flexible ventilation path 2 in the register body 1, and the air is blown straight forward from the air outlet 4.

  At this time, the flexible ventilation path 2 is a flat plate-shaped ventilation path that is short in the vertical direction of the upper and lower sides and long in the longitudinal direction of the left and right like the air outlet 4, but there are no movable fins in the ventilation path. It is possible to blow with very little pressure loss.

  On the other hand, when the direction of the wind is changed downward, the motor 16 is driven to rotate the rotating members 11 and 12, and the swing links 13 and 14 are raised as shown in FIG. , 26 is rotated upward. At this time, the pair of flexible membrane members 21 and 22 has their upstream end slide members 23 and 24 slid to the downstream side, and smoothly curves upwardly as shown in FIG. Similarly, the flexible ventilation path 2 between the flexible membrane member 21 and the flexible membrane member 22 is also smoothly curved upward in a mountain shape.

  Therefore, as shown in FIG. 8, the flexible ventilation path 2 connected to the inside of the air outlet 4 is directed obliquely downward from above toward the air outlet 4, and the air blown from the air outlet 4 The direction can be changed diagonally downward. At this time, the flexible ventilation path 2 between the flexible membrane member 21 and the flexible membrane member 22 is smoothly curved in a mountain shape as shown in FIG. Even in the flexible ventilation path 2 where the hand direction (vertical direction) is narrow, the air flows very smoothly, and there is little separation of the blown airflow, so that the air is efficiently blown.

  On the other hand, when the wind direction is changed upward, the motor 16 is driven to rotate the rotating members 11 and 12, and the swing links 13 and 14 are lowered as shown in FIG. , 26 is rotated downward. At this time, the pair of flexible membrane members 21 and 22 has the slide members 23 and 24 at the upstream end thereof slid downstream, and smoothly bends downward in a valley shape as shown in FIG. The flexible ventilation path 2 between the flexible membrane member 21 and the flexible membrane member 22 is similarly smoothly curved downward in a valley shape.

  Therefore, as shown in FIG. 9, the flexible ventilation path 2 connected to the inside of the air outlet 4 is directed obliquely upward from below toward the air outlet 4, and the wind blown from the air outlet 4 The direction is changed diagonally upward. At this time, the flexible ventilation path 2 between the flexible membrane member 21 and the flexible membrane member 22 is smoothly curved in a valley shape as shown in FIG. Even in the flexible ventilation path 2 where the hand direction (vertical direction) is narrow, the air flows very smoothly, and there is little separation of the blown airflow, so that the air is efficiently blown.

  In this manner, the pair of flexible membrane members 21, 22 are bent into a mountain shape or a valley shape by the wind direction adjusting mechanism 10 to curve the flexible ventilation path 2, and the wind blowing direction is set to the air outlet 4. Since it changes to a transversal direction (up-down direction), the ventilation direction of the air blower outlet 4 can be changed smoothly up and down. Moreover, there is no movable fin which is easy to generate pressure loss inside the ventilation path or the air outlet 4, and the pressure loss at the time of ventilation can be reduced significantly.

  Furthermore, since there are no movable fins inside the air outlet 4, the air outlet 4 can be designed to be elongated and simple, and the design of the register front surface can be improved. In addition, since the flexible ventilation path 2 formed by the pair of flexible membrane members 21 and 22 is smoothly curved in the vertical direction to change the blowing direction of the wind, the blowing air current is less separated and the air flow is performed with a sufficient amount of air. It can blow while changing direction smoothly.

  In the above embodiment, the support plates 25 and 26 having a certain width (the width in the ventilation direction) are attached to the downstream end portions of the pair of flexible membrane members 21 and 22. The width may be shortened, and as shown in FIG. 10, a pair of support rods 35 and 36 in the form of rods instead of plates are rotatably disposed inside the air outlet 4 and The downstream end portions of the pair of flexible membrane members 21 and 22 can be fixed to the support rods 35 and 36. When the support plates are the support rods 35 and 36, the rocking links 13 and 14 and the rotating members 11 and 12 of the wind direction adjusting mechanism 10 are not necessary, and instead of the pair of flexible membrane members 21 and 22 Gears are attached to both end portions of the support rods 35 and 36 fixed to the downstream end portions, the gears are engaged with the pinions of the motor, and the pair of support rods 35 and 36 are rotated in the same direction by the motor. Thus, the pair of flexible membrane members 21 and 22 are bent.

  In the above-described embodiment, the register having the air outlet 4 that is long in the horizontal and horizontal direction and short in the vertical and vertical directions and elongated in the horizontal direction has been described. A pair of flexible membrane members may be arranged in the vertical direction in a register body having a long and short air blowout port that is long in the horizontal direction and short in the horizontal direction. In this case, the pair of flexible membrane members bend in the horizontal direction by the rotation of the support plate or the support rod, and change the blowing direction of the air outlet to the left and right.
