Description

  The present invention relates to a register for adjusting air blowing used in an air conditioner such as an automobile, and more particularly to a register in which an air blowing outlet is elongated and thin and has a non-rectangular shape such as a substantially elliptical shape.

  As a register for adjusting air blowing used for air outlets for air conditioning of automobiles, etc., a front movable louver and a rear movable louver are arranged in a bezel or a retainer that forms a ventilation path, arranged in a crosswise direction, and the bezel A resistor that adjusts the air blowing direction up, down, left and right by changing the angle of each fin of the front movable louver and rear movable louver when air is blown out from the air outlet provided in the vehicle is generally used in air conditioners of automobiles, etc. ing.

  In such a register, mainly because of the design and design demand, the air blower outlet is formed in a thin and thin shape, and a register having a small number of front fins of about 1 to 3 inside the air blower outlet is an automobile. (See, for example, Patent Document 1).

JP 2002-103954 A

  In addition, as a thin register of this type, from the overall design of the instrument panel to which the register is mounted, only one front fin can be rotated as a front movable louver in the approximate center of the elongated air outlet. A register having a non-rectangular shape such as an ellipse has been developed.

  However, when the front shape of the air outlet is formed in an irregular shape such as an ellipse different from the rectangle, the air fin is simply arranged at the center along the longitudinal direction of the ellipse of the air outlet. Since the width dimension of the blower outlet in the short direction is different along the longitudinal direction, it is difficult to ensure good wind directivity when the front fin is shaken, and it is difficult to blow in a desired direction.

  For this reason, it has been studied to improve the directivity by arranging the auxiliary fin on the side of the front fin and rotating the front fin and the auxiliary fin in the air blowing direction, but the shape of the air outlet is non-rectangular. Because of the substantially elliptical shape, it is difficult to efficiently guide the wind in the rotation direction (swing direction) of the front fin with one flat auxiliary fin, and there is a problem that the directivity of the wind is poor.

  The present invention solves the above-mentioned problems, and is a thin register in which the front shape of the air outlet is a non-rectangular shape, and a register capable of improving the directivity of wind when the front fin is shaken. The purpose is to provide.

An edge of the air outlet is formed in a curve, and a plurality of auxiliary fins are adjacent to at least one side of the front fin and are substantially parallel to the tangential direction of the curve and hidden inside the side edge of the air outlet The support fins of the auxiliary fins are supported inclined with respect to the support shafts of the front fins, and the link fins rotate the front fins so that the auxiliary fins rotate in synchronization with the front fins. The auxiliary fins are connected to each other.

  According to the register of the present invention, even if the front shape of the air outlet is a deformed shape such as an ellipse and one front fin is arranged in the central longitudinal direction, A plurality of auxiliary fins are arranged adjacent to the front fin and hidden inside in parallel to the tangential direction of the curve of the edge, and each auxiliary fin has an axis whose axis is inclined with respect to the support axis of the front fin. Since each auxiliary fin is supported and linked to the front fin by each link bar so that each auxiliary fin rotates in synchronization with the front fin, when the front movable louver is shaken, along the curved edge of the front fin and the air outlet The plurality of auxiliary fins rotate in the same direction together with the front fin, and thereby, even if the air outlet is non-rectangular and irregular, the directivity of the wind during blowing can be improved. In addition, since the auxiliary fin is hidden behind the edge of the air outlet, it is possible to ensure good design of the register.

  Here, in the register, the front shape of the air outlet is formed in a vertically long elliptical shape that is long in the vertical direction and short in the horizontal direction, and one side portion of the front shape protrudes to the downstream side and the other side portion is The front shape of the air outlet may be inclined so as to recede to the upstream side, and the front fin of the front movable louver may be arranged in a substantially central longitudinal direction of the air outlet.

  Further, in the register, an auxiliary passage is formed as a concave portion for the auxiliary fin in a side portion in the ventilation path, and the plurality of auxiliary fins can be accommodated in the auxiliary passage. Further, the auxiliary passage may be arranged on a side portion of the ventilation path inside the edge portion on the protruding side of the air outlet, and the plurality of auxiliary fins may be pivotally supported on the wall portion of the auxiliary passage. .

  According to this, when the front of the air outlet is inclined in the short side direction (left and right lateral direction), when the front movable louver is swung to the rearward side in the lateral direction of the air outlet, the projection of the air outlet Since the airflow that flows outside the ventilation from the side smoothly passes through the auxiliary passage of the ventilation passage and is guided well by the auxiliary fins in the swing direction of the front movable louver, it is possible to improve the directivity of the wind during blowing .

  Further, in the register, as the plurality of auxiliary fins, the first auxiliary fin and the second auxiliary fin are arranged along the longitudinal direction of the air outlet on the inner side of the protruding side of the air outlet. It can be constituted as follows. Further, the first auxiliary passage and the second auxiliary passage are formed in the side portion of the air passage along the longitudinal direction of the air outlet and substantially parallel to the tangential direction of the edge of the air outlet, The first auxiliary fin may be pivotally supported on the first auxiliary passage and the second auxiliary fin may be pivotally supported on the second auxiliary passage. According to this, the air flow flowing outside the air blow from the projecting side of the air outlet smoothly passes through the first auxiliary passage and the second auxiliary passage of the ventilation passage, and the first movable fin and the second auxiliary fin move the front movable louver. Therefore, the directivity of wind at the time of blowing can be further improved.

  Further, in the register, a rear movable louver can be rotatably arranged on the upstream side of the front movable louver by arranging a plurality of rear fins in a direction orthogonal to the front fin.

  According to the register of the present invention, the directivity of wind when the front fin is shaken can be greatly improved even if the front shape of the air outlet is a non-rectangular and thin profile.

  As a result, the airflow flowing from the ventilation path 5 to the air outlet 15 is bent to the left side facing the front fin 7 as shown in FIG. 7, and in particular, the right side of the air outlet 15 has a protruding shape, and the right side ventilation Although the path is longer, the air flow flowing on the right side of the ventilation path 5 is well guided to the left side facing the front fin 7 by the first auxiliary fin 8 and the second auxiliary fin 9, and on the left side facing the front fin 7. It is blown toward. As described above, this register is used so that the front shape of the air outlet 15 is inclined to the left and mainly blows air toward the left occupant. The first auxiliary fins 8 and the second auxiliary fins 9 positioned on the front side can favorably blow air toward the left side facing the front fins 7, that is, toward the occupant.

  Further, in this state, as shown in FIG. 3, when the operation knob 6 is slid upward or downward, the rear fins 14 of the rear movable louver 4 are moved upward or downward via the rack portion 6a and the gear portion 6b. Can be turned to the side, and the blowing direction can be changed to the upper side or the lower side.

  Thus, even if the front shape of the air outlet 15 is an odd shape such as an ellipse and the front fin 7 is arranged in the central longitudinal direction, the edge of the air outlet 15 is provided. The first auxiliary fin 8 and the second auxiliary fin 9 are arranged adjacent to and inward of the front fin 7 substantially in parallel with the tangential direction of the curve, and the first auxiliary fin 8 and the second auxiliary fin 9 are Each link bar is supported so that the support shafts 8a and 9a are supported by tilting with respect to the support shaft 7a of the front fin 7 and the first auxiliary fin 8 and the second auxiliary fin 9 are rotated in synchronization with the front fin 7. Since the front movable louver 3 is swung because it is connected to the front fin 7 by 18, 19, the first auxiliary fin 8 and the second auxiliary fin 9 along the curved edges of the front fin 7 and the air outlet 15 are moved forward. Rotate in the same direction with the fins 7, so that non-rectangular and irregularly shaped sky Even outlet, it is possible to improve the directivity of the air during blowing. Moreover, since the 1st auxiliary | assistant fin 8 and the 2nd auxiliary | assistant fin 9 are hidden behind the edge part of the air blower outlet 15, the favorable design property of a register | resistor can be ensured.

  In addition, since the air outlet 15 of the said register | resistor becomes substantially elliptical shape, the two auxiliary fins, the 1st auxiliary fin 8 and the 2nd auxiliary fin 9, were arrange | positioned along the same vertical direction as the front fin 7. FIG. However, depending on the irregular shape other than the ellipse of the air outlet, three or more auxiliary fins can be provided. Further, the plurality of auxiliary fins can be disposed on the opposite side to the above-described embodiment, that is, on the left side in the air outlet.

  In the above embodiment, the first auxiliary fin 8 and the second auxiliary fin 9 are arranged on the right side of the front fin 7 toward the front of the register, that is, on the side protruding the front of the air outlet 15. Auxiliary fins can also be arranged on the left side of the front of the air outlet 15 on the retracted side.

  Further, the front shape of the air outlet 15 of the register of the above embodiment is such that the right side protrudes downstream and the left side recedes upstream, but on the contrary, the air outlet The front left side portion may be protruded downstream and the front right side portion may be retracted upstream, or the front shape of the air outlet may be a non-inclined vertical surface. Moreover, although the shape of the air outlet 15 is a vertically long substantially elliptical shape, it can be a horizontally long substantially elliptical shape or an irregular shape other than an elliptical shape.
