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 in particular, has an elongated air outlet that is long in a longitudinal direction and short in a short direction, and is long inside an air outlet. The present invention relates to a resistor provided with a small number of fins along a direction.

  As a register for this type of air blowing adjustment, in a bezel or retainer that forms a ventilation path, a laterally movable louver and a longitudinally movable louver are arranged back and forth, and when blowing air from an air outlet provided in the bezel, A register that adjusts the air blowing direction by changing the angle of each fin of the laterally movable louver and the vertically movable louver 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

  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. The number of fins is small compared to the fins of the front movable louver of a normal register.

  However, in a register having a long and thin air outlet in the longitudinal direction of the fin, when the number of fins along the longitudinal direction is a small number, for example, about 1, 2, the direction of the fin is changed to the short direction of the air outlet. However, it is difficult to change the direction of the wind sufficiently in that direction, and the directivity of the wind is poor.

  That is, in a register provided with an elongated air outlet 33 that is long in the longitudinal direction and short in the lateral direction, as shown in FIG. 9, the number of fins 31 of the front movable louver 30 is a small number of about 1 to 3. The air flow is narrowed in the vertical direction of FIG. 9 in the short ventilation path 32 in the short direction, and is further restricted by the air resistance by the fins 31.

  For this reason, when passing through the ventilation path 32, the air flow having a certain level of blowing pressure is throttled in the short direction, and is accelerated and blown out in the linear direction. For this reason, even if a small number of fins 31 such as one or two sheets are changed upward or downward, as shown in FIG. The bend is strong and easily affected. For this reason, the wind is difficult to bend in the direction in which the fins 31 face, and when the direction of the fins 31 of the front movable louver 30 is changed, there is a problem that the directivity of the wind tends to deteriorate.

  The present invention has been made in view of the above points, and when the direction of fins is changed in a register having a long and narrow air outlet and a small number of fins provided along the longitudinal direction inside the air outlet. An object is to provide a register capable of improving the directivity of wind.

To achieve the above object, the register of the present invention, comprises an air outlet of the elongate a short horizontal long in the lateral direction in the longitudinal direction, the inside of the air outlet, before along the longitudinal movable louver There is provided, on the upstream side of the front movable louver, the movable louver after journaled a plurality of longitudinal fins rotatably are disposed register, only one lateral fin in the front movable louver, The rotating shafts at both ends are supported by bearings on both side walls in the air outlet, and can be rotated toward the longitudinal direction of the air outlet . The lateral fin is slidably fitted toward the longitudinal direction, and is provided so as to engage with the longitudinal fin of the rear movable louver by sliding to rotate the longitudinal fin to the left and right. , the upper inner surface and lower inner surface along the longitudinal direction of the air outlet, an upstream side and a downstream side Chevron ridges having an inclined surface is formed along the longitudinal direction of the lateral fins, the inclined surface of the upstream side of the 該山 shaped ridges which characterized by being formed toward the lateral fins.

Here, the chevron convex Article, it is preferably formed continuously with the same cross section in the longitudinal direction of the air outlet.

In addition, the inclined surface on the downstream side of the chevron ridge can be formed by a front inclined surface that is open so as to spread forward.

The configuration registers, also horizontal fin before the movable louver be only one, the air flow through the air passage, when blown out from the air outlet, an upper inner surface and lower inner surface of the air outlet flows along the inclined surface of the upstream side of the chevron convex provided to face the bent front near the center of the horizontal fin of the movable louvers. Thereby, the air flow blown out from the air outlet is bent in the direction of the horizontal fin so that most of the air flow flows along the surface of the horizontal fin of the front movable louver, and only one horizontal fin is blown into the air outlet. Even in the case of the register provided on the inner side, the directivity of the wind when the direction of the horizontal fin is changed can be effectively improved.

Further, the angled ridges are continuously formed with the same cross section in the longitudinal direction of the air outlet, and further, the front inclined surface is opened so that the downstream side surface of the angled ridges spreads forward. If it is formed, the directivity of the wind when the direction of the fins of the front movable louver is changed can be further improved.

  The retainer 2 is formed in a substantially square duct shape, and an air passage 21 is formed therein. Bearing portions that pivotally support the vertical fins of the rear movable louver 4 are formed at predetermined intervals on the upper and lower walls of the front edge portion of the retainer 2. A bezel 1 in which a substantially rectangular air outlet 10 is formed in the front is fitted to the front portion of the retainer 2 in a state where the air outlet 10 is aligned with the opening of the air passage 21.

  The front movable louver 3 includes one horizontal fin 13 and an operation knob 5 that is slidably fitted on the horizontal fin 13. As shown in FIG. 6, the horizontal fins 13 are provided with pivot shafts 14 at both ends. As shown in FIG. 6, the pivot shafts 14 on both sides of the horizontal fins 13 are inserted into the bearings on both side walls of the bezel 1 and can rotate. Supported by As described above, the operation knob 5 is externally fitted to the horizontal fin 13 so as to be slidable left and right, and a rack-like tooth portion 6 is provided laterally at the rear portion of the operation knob 5. This tooth portion 6 meshes with a sector gear 7 of a vertical fin 15 to be described later, and changes the direction of the vertical fin 15 to the left and right.

  The rear movable louver 4 is configured by vertically arranging a plurality of vertical fins 15 in the retainer 2 and arranging them side by side at regular intervals. As shown in FIG. 5, the rotation shafts 16 project from the upper and lower portions of the vertical fins 15, and the rotation shafts 16 rotate around the bearing portions provided on the upper wall and the lower wall in the retainer 2. It is movably fitted. Further, as shown in FIG. 3, link members 17 are connected to the rotation shafts 16 at the top of each vertical fin 15, and these link members 17 are connected to each other by link bars 18. This link mechanism is disposed in the upper part of the retainer 2 and functions to change the directions of the vertical fins 15 of the rear movable louver 4 all at once.

  Further, as shown in FIGS. 2 and 6, the sector gear 7 is fitted to one vertical fin 15 on the right side of the rear movable louver 4 so as to protrude forward. The sector gear 7 is disposed in mesh with the teeth 6 on the rear portion of the operation knob 5 mounted on the horizontal fin 13 positioned in front of the sector gear 7. To the left and right.

  A damper plate 8 is pivotally supported behind the rear movable louver 4 in the ventilation path 21 of the retainer 2 via pivot shafts provided at both ends, and the ventilation path 21 is moved by the rotation of the damper plate 8. It has a structure that opens and closes. A link member (not shown) is pivotally attached to the left rotation shaft 8a of the damper plate 8, a long hole is formed in the link member, and a later-described pin on the damper knob 9 side is fitted into the long hole.

  As shown in FIGS. 1 and 6, the damper knob 9 is pivotally supported at the left end portion of the front portion of the bezel 1 or the retainer so as to be rotatable. The damper knob 9 has a fan-shaped knob body, and is provided with a shaft portion 9a at its axial center. The shaft portion 9a is pivotally supported by the left end of the bezel 1 or the front portion of the retainer. Further, a link portion (not shown) is integrally formed at the end of the knob main body of the damper knob 9, and a pin protrudes from the tip of the link portion, and the pin is a link member on the rotating shaft 8 a side of the damper plate 8. Engage with the slot. Thus, when the damper knob 9 is turned up or down, the damper plate 8 is turned around the turning shaft 8a to open and close the ventilation path 21.

  The register having the above-described configuration is attached to an instrument panel or a dashboard in an automobile so that the end of the retainer 2 is connected to a ventilation duct (not shown). Air sent from the ventilation duct is blown out from the ventilation path 21 in the retainer 2 through the air outlet 10.

  When the horizontal fins 13 of the front movable louver 3 and the vertical fins 15 of the rear movable louver 4 are parallel to the ventilation direction of the ventilation path 21 as shown in FIG. 5A, the air flow is straight in the ventilation path 21. To pass through between the vertical fins 15 and the horizontal fins 13 and blown forward from the air outlet 10. At this time, the air flow is blown down slightly from above and below by the mountain-shaped ridges 11 and 12 projecting from the upper and lower portions inside the air outlet 10. Therefore, the pressure loss is not so much, and the air can be blown well toward the front.

  When adjusting the air blowing direction to the left and right, the operation knob 5 is moved to the left or right for adjustment. When the control knob 5 is held and moved to the left or right, the control knob 5 slides on the horizontal fin 13 and moves in the horizontal direction (left and right horizontal direction). Accordingly, as shown in FIG. 7, the rear tooth portion 6 of the operation knob 5 rotates via the sector gear 7, and the vertical fin 15 of the rear movable louver 4 rotates left and right around the rotation shaft 16 as a fulcrum. . At this time, the turning force is transmitted to the other vertical fins 15 via the link member 17 and the link bar 18, and each vertical fin 15 rotates about its rotation shaft 16 as a fulcrum. The direction in the left-right direction changes with the rotation shaft 16 as an axis, and the air blowing direction is adjusted to the left and right.

  On the other hand, when adjusting the air blowing direction up or down, the operation knob 5 of the front movable louver 3 is turned up or down for adjustment. When the operation knob 5 is held and rotated up or down, as shown in FIG. 5 (b), the horizontal fin 13 on which the operation knob 5 is mounted rotates up and down around the rotation shaft 14, The direction of the horizontal fin 13 in the vertical direction changes about the rotation shaft 14, and the air blowing direction is adjusted up and down.

  At this time, when the operation knob 5 is operated downward, for example, and the horizontal fin 13 of the front movable louver 3 is directed downward (obliquely downward), the airflow flowing through the ventilation path 21 as shown in FIG. In the front part of the ventilation path 21, it flows along the inclined surfaces 11a and 12a on the upstream side of the opposing chevron 11 and 12 on the opposite sides of the inner surface in the vicinity of the air outlet, and is bent toward the lateral fin 13 near the center. . On the other hand, even when the horizontal fins 13 are directed obliquely upward, the airflow flowing through the ventilation path 21 is similar to the above, and the chevron convex on both sides of the front surface of the ventilation path 21 facing the inner side surface in the vicinity of the air outlet. It flows along the inclined surfaces 11a and 12a on the upstream side of the strips 11 and 12, and is bent toward the lateral fins 13 near the center.

  Thereby, most of the air flow blown out from the air outlet 10 flows along the surface of the lateral fin 13 and is bent in the direction of the lateral fin (diagonally downward or obliquely upward). Will be. Further, since the downstream side surfaces of the ridges 11 and 12 are formed by the front inclined surfaces 11b and 12b opened so as to spread forward, the direction of the horizontal fins 13 is downward as shown in FIG. 8, for example. When changed, the wind is guided by the front inclined surface 12b of the mountain-shaped ridge 12, and the wind direction is not disturbed by the edge of the opening, and the air is blown well.

  As described above, even if the register has the elongate air outlet 10 and only one horizontal fin 13 as the front movable louver 3 is provided in the front portion of the air passage 21, the direction of the horizontal fin 13 is changed. The air flow surely changes in the direction toward the horizontal fins 13, and the directivity of the wind when adjusting the horizontal fins 13 can be maintained well. This also makes it possible to put the register into practical use even if it has a long and narrow slit-like air outlet considering design.

  In the above embodiment, only one horizontal fin 13 is provided on the front movable louver 3, but two or three horizontal fins are arranged in parallel in the horizontal direction and along the longitudinal direction of the elongated air outlet. Two to three horizontal fins can be juxtaposed inside the lever.

  In the above, for the register having the horizontally long air outlet 10, the horizontal fin 13 is provided in the front movable louver 3 and the vertical fin 15 is provided in the rear movable louver 4, but these are rotated 90 degrees. In addition to providing a vertically long air outlet, one to three vertical fins may be provided on the front movable louver, and a plurality of horizontal fins may be provided side by side on the rear movable louver. In this case, an angled convex shape is provided on both the left and right sides inside the vertically long air outlet.

  In the above embodiment, the rectangular air outlet 10 is used. However, the air outlet 10 is not necessarily rectangular, and may be an air outlet having an elongated and odd shape such as an ellipse.
