Description

  The present invention relates to an air blowing member.

  In vehicles such as automobiles, an instrument panel is installed in the front part of the passenger compartment.

  The instrument panel is provided with an air blowing member for blowing air for air conditioning toward the vehicle interior.

  In such an air blowing member, a plurality of fins are installed so as to be able to tilt in an aligned state with respect to the inside of the air outlet provided at the tip of the cylindrical body through which air for air conditioning passes. (For example, refer to Patent Document 1).

JP 2008-87514 A

  However, the air blowing member described in Patent Document 1 has the following problems.

  That is, in the vicinity of the air outlet in the cylindrical body, a tilting space is provided that allows tilting of the end fin located at the end in the alignment direction among the plurality of fins.

  And if air for air conditioning enters into this tilting space and it comes out straight to the outlet, the wind direction adjustment function by the end fins will not work, so the air for air conditioning will be straight in the tilting space It is necessary to provide a structure that does not pass through.

  In view of this, an intrusion restricting portion for restricting the air for air conditioning from entering the tilting space is provided for the inlet portion or the end fin of the tilting space.

  However, since the intrusion restricting portion needs to not prevent the end fins from being tilted, the air-conditioning unit from the clearance (tilt clearance) secured for tilting the end fins, no matter how complex the structure is. It was difficult to avoid the entry of air.

  When air for air conditioning enters into the tilting space from the tilting clearance provided in the intrusion restricting section, the air for air conditioning stays in the tilting space, or vortex in the tilting space due to the retained air. For example, air resistance for air conditioning around the end fins increases.

  Accordingly, the main object of the present invention is to solve the above-described problems.

In order to solve the above problems, the present invention provides:
Inside the tip of the cylindrical body that passes air for air conditioning, a plurality of tiltable fins are installed in an aligned state,
In the air blowing member provided in the cylindrical body, a tilting space that allows tilting of the end fin located at the end in the alignment direction among the plurality of fins is provided.
A guide surface is provided in the tilting space to guide air for air conditioning that has entered the tilting space to the outside of the tilting space.

  According to the present invention, with the above configuration, the air for air conditioning that has entered the tilting space can be smoothly guided toward the outside of the tilting space.

It is the longitudinal cross-sectional view which looked at the air blowing member concerning Example 1 from the side. It is the elements on larger scale of FIG. It is a longitudinal cross-sectional view which shows the state which turned the fin upward in FIG. It is a longitudinal cross-sectional view which shows the state which turned the fin downward in FIG. It is the longitudinal cross-sectional view which looked at the air blowing member concerning Example 2 from the side. It is the longitudinal cross-sectional view which looked at the case where the guide surface is not provided in the space for tilting, seeing the air blowing member from the side. In FIG. 5, it is a longitudinal cross-sectional view which shows the case where an end fin is made into the bending shape.

Hereinafter, the present embodiment will be described in detail with reference to the drawings.
1 to 6 are for explaining this embodiment.

  <Configuration> The configuration of this embodiment will be described below.

  In vehicles such as automobiles, an instrument panel is installed in the front part of the passenger compartment.

  The instrument panel is provided with an air blowing member for blowing air for air conditioning toward the vehicle interior.

As shown in FIG. 1, the air blowing member 1 is installed in an aligned state with a plurality of tiltable fins 4 with respect to the inside of the distal end portion of a cylindrical body 3 through which air 2 for air conditioning is passed. It is assumed that
Then, a tilting space 6 capable of allowing tilting of the end fin 5 located at the end in the alignment direction among the plurality of fins 4 is provided in the cylindrical body 3.

  Here, the cylindrical body 3 is, for example, a rectangular cylinder. And the front-end | tip part of the cylindrical body 3 is also made into the square-shaped opening. A finisher 9 having a blower outlet 8 that is slightly smaller than the distal end portion is attached to the distal end portion of the cylindrical body 3 via a short rectangular tubular guide member 7. Note that the guide member 7 may be configured integrally with the cylindrical body 3.

  In this case, the fins 4 are for adjusting the wind direction in the vertical direction, and are installed in a horizontal state (horizontal fins). The plurality of fins 4 have at least the end fins 5 and the intermediate fins 11 described above. These fins 4 are installed at a position on the front side (guide member 7) of the air outlet 8 in a state of being aligned in the vertical direction. Support shafts 12 extending in the left-right direction are provided at both ends of each fin 4. The support shaft 12 is supported by the left and right side surfaces of the guide member 7. The plurality of fins 4 are tilted in the vertical direction in conjunction with the link member.

  More specifically, inclined surfaces 13 and 14 are provided on the inner side of the guide member 7 at least on the upper side and the lower side so as to restrict the air 2 for air conditioning toward the air outlet 8. Among these, the upper inclined surface 13 has a downward slope toward the upper edge of the air outlet 8. Further, the lower inclined surface 14 has an upward slope toward the lower edge of the air outlet 8. And the above-mentioned fin 4 (intermediate fin 11 and end fin 5) is provided in the range of the blower outlet 8 substantially.

  The tiltable end fin 5 is provided at a position in the vicinity of the upper end portion of the lower inclined surface 14 (or downstream in the blowing direction of the air 2 for air conditioning). Note that a similar tiltable end fin 5 can also be provided at a position near the lower end of the upper inclined surface 13.

  In this case, the tilting space 6 is a retreat space provided on the lower side of the end fin 5 in order to tilt the end fin 5 upward, and is provided by denting a portion near the upper end of the lower inclined surface 14. It has been.

  In addition, as shown in FIG. 1, the air 2 for air conditioning is blown off horizontally by orienting the end fins 5 horizontally. Further, as shown in FIG. 2, the air 2 for air conditioning is blown upward by turning the end fins 5 upward. Then, as shown in FIG. 3, the air 2 for air conditioning is blown downward by turning the end fins 5 downward. Since a gap (tilting gap) is ensured between the end fin 5 and the tilting space 6 by design, the tilting space 6 always has air conditioning air 2 in any case. Will enter.

  Further, on the back side of the fin 4, a vertical fin 16 for adjusting the wind direction in the left-right direction is provided (vertical fin). A plurality of the fins 16 are installed in a state of being aligned in the left-right direction. At both end portions (upper and lower end portions) of the fin 16, support shafts 17 extending in the vertical direction are provided. The support shaft 17 is supported on the upper and lower surfaces of the cylindrical body 3. The plurality of fins 16 are tilted in the left-right direction in conjunction with the link member. These fins 16 are operated by operating levers 18 that are slidably attached to the fins 4 (intermediate fins 11).

  The air blowing member 1 described above can also be used after being rotated 90 degrees vertically and horizontally. In this case, the vertical and horizontal directions may be replaced.

  In contrast to the basic configuration as described above, this embodiment has the following configuration.

  (1) A guide surface 21 is provided in the tilting space 6 to guide the air-conditioning air 2 a that has entered the tilting space 6 to the outside of the tilting space 6.

  Here, the outside of the tilting space 6 is the inside of the guide member 7 or the inside of the air outlet 8. The guide surface 21 can guide the air 2 for air conditioning toward the inside of the air outlet 8 regardless of the direction of the end fins 5 and without being interrupted on the way.

  In this case, a slight gap 25 is formed between the tip of the end fin 5 and the lower edge of the blower outlet 8 of the finisher 9. The guide surface 21 guides the air-conditioning air 2 a that has entered the tilting space 6 toward the gap 25. The air 2a for air conditioning is guided through the gap 25 so as to escape from the air outlet 8 substantially upward in the figure. In this way, the air conditioning air 2a guided into the air gap 2 from the gap 25 substantially upwards in the figure, thereby entering the tilting space 6 by the air conditioning air 2 passing through the central portion of the air outlet 8. It can be expected that negative air 2a is sucked.

  (2) As shown in FIG. 2, the guide surface 21 is configured such that the end fin 5 is tilted to the maximum extent toward the inside of the tilting space 6, and the end fin 5 is tilted toward the tilting space 6. It has an inclined surface parallel to the surface 5a.

  Here, the inclined surface to be the guide surface 21 is preferably the bottom of the tilting space 6. Thereby, the guide surface 21 is configured as a part of the tilting space 6.

(3) The said end fin 5 shall have a linear fin shape (straight fin).
Then, the support shaft 12 for tilting the end fin 5 is provided on the front end side of the linear end fin 5.

  Here, the front end side of the end fin 5 is an edge portion on the air outlet 8 side or the vicinity thereof. By providing the support shaft 12 on the front end side of the linear end fin 5, the end fin 5 tilts in a fan shape around the support shaft 12 on the front end side when viewed from the side. . Therefore, the tilting space 6 can be the simplest side-shaped (fan-shaped) space. As described above, when the bottom portion of the tilting space 6 is the guide surface 21, the guide surface 21 is a straight inclined surface that rises forward and corresponds to the radius of the tilting space 6 that is fan-shaped in a side view. It becomes.

  When the end fin 5 is tilted to the maximum extent toward the inside of the tilting space 6, the surface 5 b of the end fin 5 opposite to the tilting space 6 is substantially flush with the tilted surface 14 described above. It is installed to be connected to. Therefore, the guide surface 21 has a minimum size close to a stepped shape in which the downstream side portion of the inclined surface 14 is recessed by substantially the thickness of the end fin 5. The guide surface 21 is substantially parallel to the inclined surface 14.

  (4) As shown in FIG. 1 (FIG. 3), the guide surface 21 may be provided integrally with the finisher 9 attached to the tip of the cylindrical body 3.

  Here, the finisher 9 is attached to the tip of the cylindrical body 3 as a decoration member or the like.

  (5) Or, as shown in FIG. 4, the guide surface 21 may be provided separately from the tubular body 3 and the finisher 9 attached to the tip of the tubular body 3. .

  In this case, the guide surface 21 is provided integrally with the guide member 7.

  (6) Alternatively, the guide surface 21 may be configured by projecting a portion near the tip of the cylindrical body 3 toward the inside of the cylindrical body 3.

  In this case, the guide surface 21 is a protrusion or the like that protrudes integrally with the lower surface of the cylindrical body 3.

  <Operation> The operation of this embodiment will be described below.

  Air-conditioning air 2 generated by the vehicle air-conditioning apparatus is used to adjust the environment of the passenger compartment by being blown out from the air blowing member 1 provided on the instrument panel toward the passenger compartment. In the air blowing member 1, air 2 for air conditioning is blown out from the outlet 8 of the finisher 9 through the inside of the cylindrical body 3 and the inside of the guide member 7 attached to the distal end portion of the cylindrical body 3. The At this time, the fins 4 provided inside the tip of the cylindrical body 3 are tilted up and down to adjust the wind direction in the vertical direction. Further, the fin 16 provided on the back side of the fin 4 is tilted to the left and right by using the operation lever 18 to adjust the wind direction in the left-right direction.

  Here, by providing the inclined surfaces 13 and 14 on the guide member 7 at the tip of the cylindrical body 3 and narrowing the air 2 for air conditioning toward the air outlet 8, the wind speed can be increased. Further, below the air outlet 8, the air-conditioning air 2 is guided to the end fin 5 by the inclined surface 14, so that the wind direction adjusting function by the end fin 5 can be made effective.

  <Effect> According to this embodiment, the following effects can be obtained.

  (Effect 1) The air 2a for air conditioning that has entered the tilting space 6 is guided to the outside of the tilting space 6 (in this case, inside the guide member 7 and the outlet 8). A guide surface 21 was provided. As a result, the air conditioning air 2 a that has entered the tilting space 6 can be smoothly guided toward the inside of the air outlet 8 while being rectified by the guide surface 21.

  Therefore, for example, as shown in FIG. 5 and FIG. 6, the air 2 for air conditioning enters and stays in the tilting space 6 where the air 2 for air conditioning is not supposed to enter. It is possible to prevent the air 2 from generating vortices in the tilting space 6 and to reduce the airflow resistance of the air conditioning air 2 around the end fins 5. 5 and 6 show an example in which the guide surface 21 is not provided in the tilting space 6.

  Further, the air 2 that has entered the tilting space 6 is smoothly guided toward the air outlet 8 by the guide surface 21 so that the air 2 for air conditioning does not enter the tilting space 6. Therefore, it is not necessary to make the intrusion control structure complicated. This intrusion regulation structure is complicated in structure and tends to require high dimensional accuracy. However, the above-described guide surface 21 has a simple structure and does not require particularly high dimensional accuracy, and is structurally advantageous. It is. Therefore, it is possible to simplify the structure around the end fin 5 of the tilting space 6.

  (Operation Effect 2) The guide surface 21 has an inclined surface parallel to the surface 5a on the tilting space 6 side of the end fin 5 when the end fin 5 is tilted to the maximum extent toward the inside of the tilting space 6. It was supposed to be. As a result, the air-conditioning air 2a that has entered the tilting space 6 can be guided toward the air outlet 8 without difficulty. Moreover, the clearance gap between the guide surface 21 and the end fin 5 can be made small. Furthermore, by making the bottom portion of the tilting space 6 the guide surface 21, the tilting space 6 can be minimized so that no useless space is generated in the tilting space 6.

  (Effect 3) The end fins 5 are linear fins. Until now, as an intrusion restricting structure for preventing air-conditioning air 2 from entering the tilting space 6, for example, as shown in FIG. 6, the end fins 5 are bent. (Bent fin 51). However, when the end fins 5 are bent as described above, the end fins 5 are limited in shape, and the design flexibility of the end fins 5 is impaired.

  On the other hand, the end fin 5 is provided by providing the guide surface 21 in the tilting space 6 and actively guiding the air 2 for air conditioning that has entered the tilting space 6 to the outside of the tilting space 6. Can be improved in a linear fin shape. Therefore, the shape limitation of the end fin 5 as in the past can be eliminated, and the degree of freedom in design can be improved.

  Further, the support shaft 12 was set on the tip side of the end fin 5 having a linear fin shape. As a result, the end fin 5 tilts in a fan shape around the support shaft 12 when viewed from the side, so that the tilting space 6 has the simplest side shape (fan shape). Can do. And the guide surface 21 can be provided with respect to the bottom face (the linearly inclined surface corresponding to a fan-shaped radius) of the tilting space 6 which is fan-shaped in a side view. This straight inclined surface becomes the inclined surface of (2) as it is, which is structurally advantageous. The guide surface 21 is optimal for efficiently guiding the air-conditioning air 2 a that has entered the tilting space 6 to the air outlet 8.

  (Operation effect 4) The guide surface 21 is provided integrally with the finisher 9 attached to the tip of the cylindrical body 3. Thereby, the structure of the cylindrical body 3 can be simplified.

  (Operation Effect 5) The guide surface 21 is provided separately from the cylindrical body 3 and the finisher 9 attached to the distal end portion of the cylindrical body 3. Thereby, the member which comprises the guide surface 21 can be reduced in size, and can be made more accurately.

  (Effect 6) The guide surface 21 was made to protrude toward the inside of the cylindrical body 3 at a portion near the tip of the cylindrical body 3. Thereby, since the guide surface 21 is integrally provided on the cylindrical body 3 itself, the number of parts constituting the guide surface 21 can be reduced, and the peripheral structure of the guide surface 21 can be simplified.

  While the embodiments have been described in detail with reference to the drawings, the embodiments are merely illustrative. Therefore, the present invention is not limited only to the embodiments, and it goes without saying that design changes and the like within a range not departing from the gist are included in the present invention. Further, for example, when each embodiment includes a plurality of configurations, it is a matter of course that possible combinations of these configurations are included even if not specifically described. Further, when a plurality of embodiments and modification examples are disclosed, it is needless to say that possible combinations of configurations extending over these are included even if not specifically described. Further, the configuration depicted in the drawings is of course included even if not particularly described. Further, when there is a term of “etc.”, it is used in the sense that the equivalent is included. In addition, when there are terms such as “almost”, “about”, “degree”, etc., they are used in the sense that they include those in the range and accuracy recognized by common sense.
