Description

  The present invention relates to a register used for an air outlet for ventilation or air conditioning in an automobile interior, and more particularly to a register for preventing condensation on an outer surface that is likely to be generated by blowing cold air.

  As an air conditioning register for automobiles, a cluster is attached so as to cover the periphery of the front opening of the retainer that has a ventilation path inside, and the front movable louver and rear movable louver for adjusting the wind direction are moved back and forth in the ventilation path. A register having a configuration arranged in a wide range is widely used (see Patent Document 1 below).

  In this type of register, a rear movable louver is disposed on the upstream side in the air passage of the retainer. After that, the movable louver 33 has a plurality of vertical fins 34 projecting upward and downward as shown in FIG. The provided support shaft is provided by being inserted into the bearing hole of the belt-like bearing plate 32, and each vertical fin 34 can be rotated right or left around the support shaft. The bearing plate 32 that pivotally supports each vertical fin 34 is fitted into the front edge portion of the retainer 30, and the cluster 31 is fitted into the front surface portion of the retainer 30 so as to cover the periphery of the front opening portion of the retainer 30.

  Since the bearing plate 32, the retainer 30, the cluster 31 and the like constituting each part of the register are molded by synthetic resin, there is a variation in dimensions due to an error within the dimensional tolerance of each member. The support shaft is formed of a synthetic resin softer than other members so as to support the support shaft with an appropriate frictional resistance. For this reason, as shown in FIG. 8, gaps S are easily generated between the bearing plate 32 and the retainer 30 of the assembled register and between the bearing plate 32 and the cluster 31.

  The clearance S generated between the bearing plate 32 and the retainer 30 or between the bearing plate 32 and the cluster 31 is a clearance that passes from the ceiling wall of the ventilation passage 35 to the inside of the cluster 31 when viewed from the ventilation passage 35 in the retainer 30. The wind flowing through the path 35 tends to leak out from the gap S to the inside of the cluster 31.

Japanese Patent Laid-Open No. 2004-210111

  In particular, when the rear movable louver 33 or the front movable louver is adjusted so that the vertical fins 34 or the horizontal fins are swung at an angle to stop air blowing, the air pressure in the retainer 30 increases, and the gap S inevitably increases. Air tends to leak upward.

  For this reason, when the air conditioner connected to the register performs a cooling operation, the cooled cold air leaks upward from the gap S and hits the inside of the cluster 31, the inside of the cluster 31 is cooled, and the cluster 31 itself is To be cooled. At this time, when the humidity in the passenger compartment is relatively high, there is a problem that condensation occurs on the upper surface of the cluster 31 and the cluster 31 sweats. Therefore, it has been attempted to attach a heat insulating material such as a non-woven fabric to the inside of the cluster 31 to prevent the cooling of the cluster 31, but the heat insulating material is manufactured by increasing the cost of parts and the number of assembling steps. The cost will increase.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a register that can prevent the occurrence of condensation on the upper surface of the cluster without adding components.

  According to this device, since the cover rib projects from the inner side surface of the cluster so as to cover the joint portion between the front end portion of the retainer and the bearing plate, the front end portion of the retainer and the bearing are provided. Even if a gap occurs in the joint where the plates are joined, and the cooling air in the ventilation path leaks from the gap, the cold air does not directly hit the wall of the cluster by the cover rib, preventing the cluster itself from cooling. It is possible to prevent condensation that tends to occur on the surface of the cluster during the cooling operation of the air conditioner.

According to a second aspect of the present invention, there is provided a register having a duct-like retainer provided with an air passage inside, a cluster attached to cover the front peripheral edge of the retainer and having an air outlet, and an air passage in the retainer.

The joint portion between the bearing plate and the retainer and / or the joint portion between the bearing plate and the inner connection portion of the cluster is formed with a step portion having a step in the thickness direction. To do.

  According to this device, even if a gap occurs at the joint between the bearing plate and the retainer or the joint between the bearing plate and the inner connection portion of the cluster, the gap is formed by a stepped portion having a step in the thickness direction. Therefore, even if the cooling air in the ventilation path leaks from the gap between the steps, the cool air does not directly hit the cluster wall, and the cluster wall is prevented from being cooled. Condensation that tends to occur on the surface can be prevented.

According to a third aspect of the present invention, there is provided a duct-shaped retainer provided with a ventilation path therein, a cluster attached to cover the front peripheral edge of the retainer and having an air outlet, and the inside of the ventilation path of the retainer. In a register having a movable louver arranged in parallel with a plurality of fins,

Cover ribs project from the inner surface of the cluster so as to cover the joint portion and are substantially parallel to the bearing plate.

  According to this device, in addition to the joint portion between the bearing plate and the retainer and / or the joint portion between the bearing plate and the inner connection portion of the cluster being formed with a step portion having a step in the thickness direction, the bearing plate Since the cover ribs project from the inner surface of the cluster substantially parallel to the bearing plate so as to cover the joint between the retainer and the retainer and / or the joint between the bearing plate and the inner connection portion of the cluster, the front end of the retainer Even if cooling air in the ventilation path leaks out from the gap, the cold air is clustered by the step portion and the cover rib. Therefore, the cluster wall portion is prevented from being cooled, and condensation that tends to occur on the cluster surface during the cooling operation of the air conditioner can be prevented.

  According to a fourth aspect of the present invention, in the register of the first or third aspect, a holding portion is provided at a front end portion of the retainer, and the cover rib is fitted and held inside the holding portion. And

  According to this device, the tip of the cover rib can be stably held with the cluster attached to the front portion of the retainer.

  According to the register of the present invention, it is possible to easily prevent the occurrence of condensation on the upper surface of the cluster without adding another part, such as attaching a heat insulating material to the inner surface of the cluster.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a first embodiment of a register mounted on an instrument panel of a vehicle, FIG. 2 is a sectional view taken along II-II of the register, and FIG. 3 is the vicinity of the upper portion of the vertical fin 4a of the register. FIG. Before and after use in this specification, the front side of the register, that is, the right side of FIG. 2, is the front, the rear side of the register, that is, the left side of FIG. 2, is the rear, and the downstream side is the front part in the ventilation path 2a. The side is the rear.

  This register includes a retainer 2 formed in a duct shape with a square cross section and a cluster 1 fitted so as to cover the front peripheral edge of the retainer 2, and the lower portion of the retainer 2 protrudes to the front. The upper part of the retainer 2 is formed in an oblique shape, and a ventilation path 2 a is formed in the retainer 2. An air outlet 1a and a knob opening 1b for a damper knob are provided on the front surface of the cluster 1 attached to the front portion of the retainer 2 at an angle.

  A front movable louver 3 is disposed at the front end of the retainer 2, and a rear movable louver 4 is disposed behind (in the rear of) the front movable louver 3, that is, upstream in the ventilation path 2 a of the retainer 2. The front movable louver 3 has a plurality of horizontal fins 3a arranged at regular intervals, and each horizontal fin 3a is held at the front portion of the retainer 2 so as to rotate about a support shaft 3b projecting on both sides. Yes. Although not shown, a crank is provided on one support shaft 3b of each horizontal fin 3a, and one link bar is connected to the tip of the crank of each horizontal fin 3a. It is structured to change its direction up and down in synchronization.

  The rear movable louver 4 is configured by vertically arranging a plurality of vertical fins 4a at regular intervals. Each vertical fin 4a has a support shaft 4b protruding at the top, a support shaft 4d protruding below the vertical fin 4a, and the rear movable louver 4 has the upper and lower support shafts 4b and 4d as axes. It is rotatably held in 2a. As shown in FIG. 3, the support shaft 4 b above the vertical fin 4 a is inserted into a shaft hole provided in the bearing plate 6 and supported.

  The bearing plate 6 is fitted between the front end portion of the retainer 2 and the inner connection portion 1c of the cluster 1 so as to be coupled. The bearing plate 6 is formed into a plate shape with a relatively soft synthetic resin, and shaft holes are provided at regular intervals. The shafts 4b of the vertical fins 4a have an appropriate frictional resistance in the shaft holes. The support shaft 4b of each vertical fin 4a is rotatably supported by the bearing plate 6.

  Further, as shown in FIG. 3, the bearing plate 6 is formed with a step portion 13 having a step in the thickness direction at a portion connected to the front end portion of the retainer 2. Further, a step 12 is provided at the front end of the retainer 2, and the step 13 on the rear side (back side) of the bearing plate 6 is fitted and assembled with the step 12 at the front end of the retainer 2.

  Further, above the bearing plate 6, a plate-like cover rib 11 includes stepped portions 12 and 13 of the retainer 2 and the bearing plate 6, and at least the entire bearing plate from the top to the joint portion of the bearing plate 6 and the retainer 2. It protrudes from the inner side of the cluster 1 so as to be covered, substantially parallel to the bearing plate 6.

  Thereby, the joint part of the bearing plate 6 and the retainer 2 and the upper part of the joint part of the bearing plate 6 and the cluster 1 are covered with the cover rib 11. Therefore, due to dimensional variation (error within dimensional tolerance) during manufacture of the bearing plate 6, the retainer 2, or the cluster 1, or the like, between the front end portion of the retainer 2 and the bearing plate 6, or the inner connection portion 1c of the cluster 1. Even if a gap S is formed between the bearing plate 6 and the bearing plate 6 as shown in FIG. 3, the gap S is covered from above by the cover rib 11. That is, the gap S generated on the outer upper surface at the joined portion of the retainer 2 and the bearing plate 6 is covered with the cover rib 11 from above.

  Moreover, since the gap S is formed by being bent along the stepped portions 12 and 13 as shown in FIG. 3, the cold air in the ventilation path 2 a leaks from the gap S to the upper and outer sides of the retainer 2 during cooling. However, the leakage amount and the leakage flow rate are minimized, and the cool air is caused to flow backward in the protruding direction of the cover rib 11 so that the cool air does not directly contact the inner surface of the cluster 1.

  On the other hand, as shown in FIG. 2, the lower support shaft 4 d of each vertical fin 4 a of the rear movable louver 4 rotates between the support plate 2 b attached to the front lower portion of the retainer 2 and the front end portion of the retainer 2. Supported as possible. A crank 4e is formed on the support shaft 4d below each vertical fin 4a, and one link bar 4f is connected to the tip of each crank 4e. All the vertical fins 4a can be synchronously changed in direction from side to side. It has a structure. Further, when the gear portion 4c is provided at the front portion of the vertical fin 4a located at the substantially central portion and meshes with the gear portion 5a provided at the rear portion of the slide knob 5, the slide knob 5 is slid in the left-right direction. The vertical fins 4a of the rear movable louver 4 are adjusted to the left and right via the gear portions 5a and 4c.

  The slide knob 5 is slidably fitted on the lateral fin 3a at the substantially center of the front movable louver 3 so as to protrude forward. This slide knob 5 adjusts the direction of each horizontal fin 3a of the front movable louver 3 up or down by its up and down rotation operation. The gear portion 5a of the slide knob 5 and the gear portion 4c of the vertical fin 4a, which are meshed at this time, are slid at their meshing positions and allow the slide knob 5 to rotate in the vertical direction.

  A damper plate 8 of a damper mechanism is disposed in the upstream side (rear part) of the ventilation path 2a in the retainer 2 so as to be capable of rotating operation in order to stop air blowing or adjust the air volume. As shown in FIG. 2, the damper plate 8 is formed in a plate shape, and a soft edge portion 8a such as a sponge sheet is attached to the edge portion thereof, and when closed, the soft edge portion 8a is passed through the inner peripheral surface of the air passage 2a. It is made to contact and the sealing property is made favorable. A damper shaft portion (not shown) protrudes from one side portion of the damper plate 8, and the damper shaft portion is fitted into a shaft support hole provided in the side wall of the retainer 2.

  As shown in FIG. 1, the other end portion of the damper plate 8 is fitted with a tip end portion of a damper support shaft 9 inserted from the outside into the insertion hole of the retainer 2. 9 and the damper shaft portion are rotatably supported. A fitting portion is provided at the tip of the damper support shaft 9, and the fitting portion of the damper support shaft 9 is fitted and fixed to the left side edge portion of the damper plate 8.

  As shown in FIG. 1, a damper lever portion 9a is provided at an outer end portion of the damper support shaft 9 in a direction perpendicular to the shaft, and a guide groove 9b is formed in the damper lever portion 9a along the longitudinal direction. A pin 7c of the knob lever portion 7a is fitted into the guide groove 9b, and the rotational operation force of the damper knob 7 is transmitted to the damper lever portion 9a. Therefore, when the damper knob 7 is rotated upward or downward, the knob lever 7a is rotated downward or upward due to the rotation of the knob body, whereby the damper support shaft 9 is rotated via the damper lever 9a. Then, the damper plate 8 rotates counterclockwise or clockwise in FIG. 2, and the ventilation path 2a is opened or closed.

  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). The air sent from the ventilation duct is blown out from the ventilation path 2a in the retainer 2 through the air outlet 1a.

  When adjusting the air blowing direction up or down, as shown in FIG. 2, when the slide knob 5 is operated up or down, the horizontal fins 3a of the front movable louver 3 rotate, and the direction changes up and down. The air blowing direction is adjusted up and down.

  When adjusting the air blowing direction to the left and right, when the slide knob 5 is operated to the right or left, the vertical fins 4a of the rear movable louver 4 rotate about the upper and lower support shafts 4b and 4d, and the left and right The direction changes in a predetermined angle range, and the air blowing direction is adjusted to the left and right.

  When the air conditioner performs the cooling operation, the cooled air passes through the ventilation path 2a and is blown from the front air outlet 1a. For example, by operating the slide knob 5 downward, the side of the front movable louver 3 is moved. When the opening ratio of the air outlet 1a decreases, such as when the fins 3a are directed downward, the air pressure of the ventilation path 2a increases.

  In such a case, if a gap S is generated in the joint portion between the bearing plate 6 and the retainer 2 or the joint portion between the bearing plate 6 and the inner connection portion 1c of the cluster 1 due to variations in component dimensions, the gap Cold air leaks from S to the upper side of the retainer 2. However, as shown in FIG. 3, the cover rib 11 extends from the inner surface of the cluster 1 to the joint between the front end of the retainer 2 and the bearing plate 6, that is, the gap S formed on the upper and outer surfaces of the retainer 2, and the cluster 1. Since the inner connecting portion 1c is projected along the wall portion of the retainer 2, that is, substantially parallel to the bearing plate 6 so as to cover the joining portion joined to the bearing plate 6, the cooling air in the ventilation passage 2a is Even if the air leaks from the gap S, the cover rib 11 causes the cool air to flow rearward along the upper outer surface of the retainer 2 and does not directly hit the wall portion of the cluster 1.

  Further, the joint between the front end portion of the retainer 2 and the bearing plate 6 fits the step portion 12 provided at the front end portion of the retainer 2 and the step portion 13 provided at the end portion of the bearing plate 6 as shown in FIG. Therefore, even if the gap S is generated in the bonded portion, the gap is bent in the flow direction. For this reason, even if the cooling air leaks through the gap S, the flow velocity and flow rate are small, and the leaked cold air does not directly hit the wall portion of the cluster 1. Therefore, the cluster 1 itself is not cooled without attaching a heat insulating material or the like to the inner side surface of the cluster 1, and condensation that tends to occur on the cluster surface during the cooling operation of the air conditioner can be prevented.

  FIG. 4 shows an enlarged partial sectional view of the vicinity of the upper portion of the vertical fin 4a in the second embodiment. About the member similar to the said embodiment, the same figure code | symbol is attached | subjected to drawing, and the description is abbreviate | omitted.

  In this example, a bearing plate 16 having a stepped portion 17 having a larger number of steps is attached between the front end portion of the retainer 2 and the inner connecting portion 1c of the cluster 1. As with the bearing plate 6, the bearing plate 16 is formed with a plurality of shaft holes at regular intervals, and the support shafts 4b of the vertical fins 4a are fitted into the shaft holes and supported rotatably.

  As shown in FIG. 4, the bearing plate 16 is provided with a step portion 17 having a plurality of steps in the thickness direction of the plate, and the step portion 17 is provided at the front end portion of the retainer 2. 12 is fitted and assembled. On the other hand, an inclined step portion 18 having an inclined shape is also formed on the front edge portion of the bearing plate 16 on the inner connection portion 1c side of the cluster 1 in the bearing plate 16, and also on the inner connection portion 1c side of the cluster 1 An inclined step portion 19 that can be fitted to the inclined step portion 18 is formed.

  The register of the second embodiment is provided with a stepped portion 17 having a plurality of stepped portions at the joint portion between the bearing plate 16 and the retainer 2 although the cover rib covering the bearing plate and the joint portion is not provided. The inclined step portions 18 and 19 are also fitted and provided at the joint portion between the bearing plate 16 and the cluster 1.

  Therefore, even when a gap S is generated in the joint portion between the front end portion of the retainer 2 and the bearing plate 16 and the joint portion between the bearing plate 16 and the inner connection portion 1 c of the cluster 1, the retainer 2 is generated on the upper and outer surfaces of the retainer 2. The clearance S is a clearance that is bent along the flow direction of the retainer 2. For this reason, even if the cooling air leaks through the gap S to the upper and outer portions of the retainer 2, the flow velocity and flow rate are small, and since the cool air flows backward, The cluster 1 itself is prevented from cooling, and condensation that tends to occur on the cluster surface during the cooling operation of the air conditioner is prevented.

  FIG. 5 shows an enlarged partial sectional view of the vicinity of the upper portion of the vertical fin 4a in the third embodiment. About the member similar to the said embodiment, the same figure code | symbol is attached | subjected to drawing, and the description is abbreviate | omitted.

As with the bearing plate, the bearing plate 25 has a plurality of shaft holes formed at regular intervals, and the support shafts 4b of the vertical fins 4a are fitted into the shaft holes and supported rotatably.

  On the other hand, the cover rib 11 is provided on the inner side surface of the cluster 1 substantially in parallel with the bearing plate 25 so as to cover the bearing plate 25 and the joint portions before and after the bearing plate 25.

  As a result, even if a gap S occurs in the joint portion between the bearing plate 25 and the retainer 2 or the joint portion between the bearing plate 25 and the inner connection portion 1 c of the cluster 1, the cover rib 11 extending from the inner surface of the cluster 1. Covers these gaps S. For this reason, even if the cooling air in the ventilation path 2a leaks out from the gap S, the cold air flows backward along the cover rib 11, and the cold air does not directly hit the inner surface of the cluster 1, and the cluster 1 itself Cooling is prevented, and condensation that tends to occur on the cluster surface during cooling operation of the air conditioner is prevented.

  FIG. 6 shows an enlarged partial sectional view of the vicinity of the upper part of the vertical fin 4a in the fourth embodiment. About the member similar to the said embodiment, the same figure code | symbol is attached | subjected to drawing, and the description is abbreviate | omitted.

  In this example, the bearing plate 26 is fitted between the front end portion of the retainer 2 and the inner connection portion of the cluster 1 so as to be coupled. As with the bearing plate, the bearing plate 26 has a plurality of shaft holes formed at regular intervals, and the support shafts 4b of the vertical fins 4a are fitted into the shaft holes and supported rotatably.

  As in the case of FIG. 3, the bearing plate 26 is formed with a step portion 13 having a step in the thickness direction at a portion connected to the front end portion of the retainer 2. Further, as shown in FIG. 6, a stepped portion 12 is also provided at the front end portion of the retainer 2, and the stepped portion 13 on the rear side (back side) of the bearing plate 6 is fitted with the stepped portion 12 at the front end portion of the retainer 2. And assembled.

And the step portion 15 of the inner connection portion of the cluster 1 is fitted, and the bearing plate 26 is attached between the retainer 2 and the cluster 1. Further, above the bearing plate 26, the plate-like cover rib 11 covers the inside including the retainer 2 and the stepped portions 12 and 13 of the bearing plate 26 from the top so that the inner side of the cluster 1 is substantially parallel to the bearing plate 26. Projected from.

  Also in this register, if a gap S is formed at the joint portion between the bearing plate 26 and the retainer 2 or the joint portion between the bearing plate 26 and the inner connection portion of the cluster 1, the cold air flows from the gap S to the upper side of the retainer 2. Although it leaks out, the bearing plate 6 covers the joint portion where the cover rib 11 from the inner surface of the cluster 1 joins the front end portion of the retainer 2 and the bearing plate 26 and the joint portion where the inner connection portion of the cluster 1 joins the bearing plate 26. Therefore, even if the cooling air in the ventilation passage 2a leaks from the gap, the cold air flows to the rear of the upper and outer portions of the retainer 2 by the cover ribs 11, and the wall portion of the cluster 1 There is no direct hit.

  Further, as shown in FIG. 6, the joint between the front end portion of the retainer 2 and the bearing plate 26 is a fit between the step portion 12 provided at the front end portion of the retainer 2 and the step portion 13 provided at the end portion of the bearing plate 26. Since the joint portion between the bearing plate 26 and the cluster 1 is also joined by fitting the step portion 27 on the bearing plate 26 side and the step portion 15 on the cluster 1 side, a gap S is generated in the joint portion. However, the gap S is bent in the distribution direction.

  For this reason, even if the cooling air leaks through the gap S, the flow velocity or flow rate is small, and the leaked cold air does not directly hit the wall portion of the cluster 1. Therefore, even if a heat insulating material or the like is not attached to the inner side surface of the cluster 1, the cluster 1 itself is not cooled, and condensation that tends to occur on the cluster surface during the cooling operation of the air conditioner can be prevented.

  FIG. 7 shows an enlarged partial sectional view of the vicinity of the upper part of the vertical fin 4a in the fifth embodiment. About the member similar to the said embodiment, the same figure code | symbol is attached | subjected to drawing, and the description is abbreviate | omitted.
