Description

  The present invention relates to a register used for an air outlet of an air conditioner such as an automobile interior, and more particularly, to a register that prevents a malfunction caused by dew condensation caused by blowing of cold air.

  As air conditioning registers for automobiles, a laterally movable louver and longitudinally movable louver for adjusting the wind direction, etc., or a barrel unit having a laterally movable louver are arranged in the ventilation path in the bezel and retainer, and air is blown upstream thereof. 2. Description of the Related Art Conventionally, a register having a structure in which a damper plate for stopping or adjusting an air volume is provided so as to be openable and closable has been widely used.

  In the following Patent Document 1, the present applicant proposes a register that has a vertically long retainer and is arranged to be able to rotate a barrel unit having a movable louver at the upper opening of the retainer and blows air obliquely upward. is doing.

  By the way, to the register at the time of cooling, cold air cooled through the evaporator is blown and passes through the retainer, but when the cold air is blown, the retainer is cooled or air leakage from the connecting portion of the retainer. Condensation may occur on the outer wall surface of the retainer. At this time, when the retainer of the register has a vertically long and inclined structure, the condensed water tends to flow downward on the inclined wall surface of the retainer.

  For this reason, when an electrical component is located below the retainer, there is a possibility that water droplets condensed on the outer wall surface of the retainer may come into contact with the electrical component. In such a case, a failure due to an insulation failure of the electrical component occurs. Therefore, when such a case is expected, a water absorbing sheet such as a foamed urethane resin sheet is attached to the outer wall surface of the retainer, and when water droplets due to condensation occur on the outer wall surface of the retainer, it absorbs the water droplets. We do not let it flow downward.

JP 2003-341355 A

  However, when such a water-absorbing sheet is attached to the outer wall surface of the retainer, water droplets condensed on the outer wall surface of the retainer during cooling are absorbed by the water-absorbing sheet and can prevent adverse effects on the electrical components below. Since parts such as a urethane foam resin sheet are required and an operation of attaching a water absorbing sheet is also required, there is a problem that the manufacturing cost of the register increases.

  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 adverse effects on electrical components due to condensation without increasing the number of components and without increasing manufacturing costs. To do.

  In the register of claim 1 of the present invention, a bezel having an outlet is attached to a downstream end portion of a retainer having an air passage formed therein, and a movable louver or barrel unit for adjusting the air direction is provided in the retainer. A lower extending portion is provided at a lower portion of the bezel so as to cover a lower side of the retainer, and an electrical component is attached to the lower extending portion at the lower portion of the bezel. Water drop ribs project from the inner surface of the extension portion between the retainer and the water drop ribs to guide and cause water drops condensed on the outer wall surface of the retainer to flow away from the electrical components. It was formed as follows.

  According to this device, when cold air flows in the ventilation passage of the register and the retainer is cooled to cause dew condensation on the outer wall surface, the dew condensation becomes water droplets and drops on the lower extension portion of the bezel. However, since the water drop ribs are provided in the lower extension of the bezel, the water drops are guided to flow away from the electrical parts by the water drop ribs, and there is no adverse effect on the electrical parts due to condensation. Is prevented. Therefore, the work of attaching the water absorbing sheet and the water absorbing sheet is not required, and the number of parts and the number of attaching steps can be reduced, and the manufacturing cost of the register can be reduced.

  Here, the water droplet rib can be formed in a substantially chevron shape in which the central portion is high and both side portions are lower than the central portion. Moreover, the rib for water drops can be formed in a substantially inclined shape with one end raised and the other end lowered.

  According to this device, it is possible to prevent an adverse effect due to condensation with a simple structure in which a substantially mountain-shaped or substantially inclined-shaped water drop rib is provided in the lower extension portion of the bezel. Is unnecessary, and the number of parts and the number of pasting steps can be reduced to reduce the manufacturing cost of the register.

  According to the register of the present invention, it is not necessary to attach the water absorbing sheet and the water absorbing sheet, and the number of parts and the number of attaching steps can be reduced, thereby reducing the manufacturing cost of the register.

It is a front view of a register showing one embodiment of the present invention. It is II-II sectional drawing of FIG. FIG. 3 is a sectional view taken along line III-III in FIG. 1. It is a rear view of the register.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a front view of an air-conditioning register 1 mounted in the vicinity of a rear seat of the passenger compartment.

  As for this register 1, the bezel 3 which has the blower outlet 5 is attached to the downstream end part (upper end part) of the cylindrical retainer 2 which formed the ventilation path 6 inside roughly, and adjusts a wind direction. A barrel unit 10 is arranged in the retainer 2 for the purpose.

  As shown in FIG. 3, the retainer 2 is formed in a duct shape having a substantially square cross section, and the downstream end of the retainer 2 is connected to the outlet frame 4 of the bezel 3, and the upstream end of the retainer 2 ( The lower end portion is connected to a blower duct (not shown) in the vehicle. A damper plate 7 of a damper mechanism for adjusting the blown air flow rate is rotatably supported by a damper shaft 7a in the ventilation path 6 of the retainer 2.

  The damper plate 7 is formed in a plate shape, and a soft edge portion 7b such as a sponge sheet is attached to the edge portion thereof. When the damper plate 7 is closed, the soft edge portion 7b is brought into contact with the inner peripheral surface of the air passage 6 so as to provide a sealing property. Good. As shown in FIG. 1, the damper knob 16 of the damper mechanism is provided at the front center of the register 1, and the rotational operation force of the damper knob 16 is transmitted to the damper shaft 7a of the damper plate 7 via a link member (not shown). The damper plate 7 opens and closes.

  The bezel 3 having the air outlet 5 is configured as a structure including the air outlet frame 4, and the air outlet 5 is formed inside the frame-like air outlet frame 4 in two portions on both sides. A front surface of the bezel 3 forms a design surface of the register 1, and a lower extending portion 3 a is extended at the lower portion of the bezel 3 so that the lower portion extends downward. Further, the downstream end portion of the retainer 2 is connected to the blower outlet frame 4 so that the air blown through the ventilation path 6 of the retainer 2 is blown out from the blower outlets 5 on both sides of the blower outlet frame 4 of the vessel 3. It has become.

  Further, as shown in FIG. 3, the retainer 2 is disposed with its downstream end facing obliquely upward and its upstream end facing obliquely downward, and the lower side surface of the outer peripheral wall 2a of the retainer 2 is obliquely downward The lower extending portion 3a of the bezel 3 is positioned so as to cover the lower surface of the outer peripheral wall 2a. For this reason, when cold air is sent into the retainer 2 and the outer peripheral wall 2a is cooled to cause dew condensation on the outer surface of the outer peripheral wall 2a, water droplets due to dew condensation are formed at the lower extension 3a of the bezel 3 located below the dewdrop. It will be dripped.

  On the other hand, as shown in FIGS. 1 and 3, an electrical component 20 such as a cigarette lighter or a switch is attached to the lower extension 3 a of the bezel 3. For this reason, when dew condensation occurs on the outer peripheral wall 2a of the retainer 2 due to the cold air during cooling and the water droplets drop onto the lower extension portion 3a of the bezel 3, the water drops flow down the lower extension portion 3a to the electrical component 20. May reach adverse effects such as poor insulation of the electrical component 20.

  Therefore, in order to guide the water droplets generated on the outer peripheral wall 2a of the retainer 2 to the position where the electrical component 20 is removed, the water droplet ribs 9 are provided on the lower extending portion 3a of the bezel 3 as shown in FIG. Is protruded from the inner surface of the lower extension 3a, that is, the retainer 2 side. As shown in FIG. 4, the water drop rib 9 is formed in a substantially mountain shape so that the central portion is high and gradually decreases from the central portion to both side end portions, and is located immediately above the electrical component 20. The water droplet is guided to the position where the electrical component 20 is removed.

  On the other hand, as shown in FIGS. 2 and 3, in the upper part of the ventilation path 6 of the retainer 2, the barrel unit 10 is arranged back and forth (up and down) around a barrel shaft 14 projecting horizontally on both sides of the barrel body 11. ) Is pivotally supported in the direction. Inside the barrel main body 11 of the barrel unit 10, a back movable louver 13 is disposed on the upstream side (back part) by pivotally supporting a plurality of movable fins 13 a so as to be pivotable to the left and right. The plurality of movable fins 13a of the rear movable louver 13 are arranged side by side in the vertical direction and at a predetermined interval on the left and right, and turn left and right by a turning shaft 13b protruding from the upper and lower portions. Yes. A link bar 13c is connected to the plurality of movable fins 13a of the inner movable louver 13 so as to rotate in conjunction with each other.

  Further, on the inner side of the barrel main body 11 of the barrel unit 10, a plurality of front fins 12 are juxtaposed (fixed) at right angles to the movable fins 13a, that is, in the horizontal horizontal direction, on the downstream side (front part) of the inner movable louver 13. Is done. Further, an operation knob 15 is slidably mounted in one of the intermediate portions of the front fin 12, and the distal end portion of the operation knob 15 is linked to the movable fin 13 a of the back movable louver 13. As a result, when the control knob 15 is held to slide left and right, the movable fin 13a of the back movable louver 13 rotates to the left and right, and the wind direction can be adjusted to the left and right. Further, when the operation knob 15 is held and slid up and down, the front fin 12 fixed to the barrel main body 11 rotates up and down around the barrel shaft 14 together with the barrel main body 11, and the barrel unit 10 is moved in the vertical direction. By rotating, the wind direction can be adjusted up and down.

  The register having the above-described configuration is mounted in the vicinity of a rear seat in an automobile or the like by connecting the end of the retainer 2 to a ventilation duct (not shown). Air sent from the ventilation duct is blown out from the ventilation path 6 in the retainer 2 through the outlet 5.

  Similarly, the cool air sent through the cooling system is sent from the ventilation duct to the ventilation path 6 in the retainer 2 and blown through the outlet 5. At this time, when the cool air flows through the ventilation path 6 or the retainer 2 is cooled due to wind leakage from the connecting portion of the retainer 2 and condensation occurs on the outer peripheral wall 2a, the condensation is caused by water droplets as shown in FIG. And drops onto the lower extension 3 a of the bezel 3. At this time, the water droplets flow downward through the lower extending portion 3a. However, since the water droplet ribs 9 are provided inside the lower extending portion 3a of the bezel 3, the water droplets are provided by the water droplet ribs 9. It is guided to a position off 20 and flows down.

  For this reason, water droplets do not adhere to the electrical component 20, and adverse effects on the electrical component 20 due to condensation are prevented. Therefore, when the register 1 is manufactured, the work of attaching the water absorbing sheet and the water absorbing sheet to the outer peripheral wall 2a of the retainer 2 becomes unnecessary, and the number of parts and the number of attaching steps can be reduced, and the manufacturing cost of the register can be reduced.

  An outline of the operation of the register 1 will be described. When the air blowing direction is adjusted up or down, the operation knob 15 is operated up or down. At this time, the barrel unit 10 rotates about the barrel shaft 14, the direction thereof changes up and down, and the air blowing direction is adjusted up and down.

  When adjusting the air blowing direction to the left or right, if the operation knob 15 is operated to the right or left, the operation knob 15 slides right or left on the front fin 12, and the movable fin 13a of the back movable louver 13 The left and right pivots 13b pivot about the upper and lower pivot shafts 13b, the left and right orientations change within a predetermined angular range, and the air blowing direction is adjusted to the left or right.

  When the blower is stopped or throttled or the closed ventilation path 6 is opened, the damper knob 16 (FIG. 1) located at the front center of the bezel 3 is pushed with a finger or the like to rotate up or down. At this time, the rotating operation force of the damper knob 16 is transmitted to the damper plate 7 through the link member, and the damper plate 7 rotates about the damper shaft 7a to stop the blowing or open the ventilation path 6 to blow the air. It can be carried out.

  In addition, this invention is not limited to said embodiment, It can implement also in the following aspects.

  In the above embodiment, the barrel unit 10 is arranged in the ventilation path 6 of the retainer 2 and the wind direction is adjusted by the operation of the barrel unit 10, but instead of the barrel unit 10, they are orthogonal to each other. A front movable louver having a plurality of movable fins and a rear movable louver may be arranged in the ventilation path 6 of the retainer 2 so as to adjust the wind direction.

  Moreover, in the said embodiment, although the rib 9 for water drops was formed in the substantially mountain shape which made the center part high and both sides were made lower than the center part, the shape of the rib for water drops made the other end high and made the other end low. It is also possible to configure such that it is formed in a substantially inclined shape and a water droplet dripping from above is guided to a location other than the electrical component.
