DETAILED DESCRIPTION OF THE INVENTION

[0010] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings. Note that the embodiments shown in the accompanying drawings are merely examples of the present invention, and the present invention is not limited to these embodiments.

[0011] <Example> The embodiment will be described with reference to the drawings.

[0012] Referring to Figure 1, the air conditioning blowout device 10 is used as a blowout device for a vehicle air conditioner. The air conditioning blowout device 10 is provided, for example, in the front part of the vehicle compartment, and blows air toward the occupants.

[0013] 2 and 3, air conditioning blower device 10 includes housing 20 into which air is blown, fin body 30 provided inside housing 20, first fin mechanism 40 that displaces fin body 30 along the air blowing direction, second fin mechanism 50 that displaces fin body 30 in the up-and-down direction, and air blow guide mechanism 60 that is provided displaceable toward fin body 30 and that guides the direction of the air to be blown out.

[0014] The housing 20 has an inlet 21 through which blown air is introduced, an outlet 22 that faces the interior of the vehicle and blows air toward the vehicle interior, a narrow section 23 formed between the inlet 21 and the outlet 22 and having an area smaller than that of the outlet 22, guide slit sections 24, 25 which are slit-like holes opened in the side surface and guide the second fin mechanism 50, and a movable wall storage section 26 that bulges out in the vertical direction so as to be able to accommodate part of the air blow guide mechanism 60.

[0015] Refer to Fig. 1. Air outlet 22 has a substantially rectangular shape. Hereinafter, a direction parallel to long side 22a of air outlet 22 (the vehicle width direction in this embodiment) will be referred to as a first direction, and a direction parallel to short side 22b, which is a side shorter than long side 22a (the up-down direction in this embodiment), will be referred to as a second direction.

[0016] In the case of the air conditioning blowout device 10 in which the blowout port 22 is long in the vertical direction, the first direction is the vertical direction, and the second direction is the vehicle width direction (and / or the front-rear direction).

[0017] The fin body 30 is provided across the first direction. The portion of the fin body 30 facing the second fin mechanism 50 is formed into a concave shape and serves as a connected portion 31 that is connected to the second fin mechanism 50. When the fin body 30 is in the normal mode, the fin body 30 is connected to the second fin mechanism 50. Note that the connected portion 31 may protrude in a convex shape toward the second fin mechanism 50.

[0018] Referring to Figure 3, in normal mode, the fin body 30 is located between the narrow section 23 and the air outlet 22 and at approximately the center of the air outlet 22 with respect to the second direction. The fin body 30 has a shape in which a substantially fan-shaped cross section extends in the first direction. The fin body 30 has a fin body pin section 32 which is a pin formed at the upstream end and is connected to the first fin mechanism 40, tapered sections 33, 33 which extend so as to widen downstream from the fin body pin section 32, and a fin body arc surface section 34 which is formed in an arc shape so as to connect the downstream ends of these tapered sections 33, 33.

[0019] 1. The first fin mechanism 40 includes, for example, a first motor 41 which is a stepping motor that operates when energized, a 1-1 gear 42 which is a gear that rotates when the first motor 41 operates, a first shaft member 43 which is a shaft that passes through the 1-1 gear 42 and is rotatably supported by the housing 20, a 1-2 gear 44 which is a gear fixed to each end of the first shaft member 43 and rotates when the 1-1 gear 42 rotates, and a 1-3 gear 45 which is a gear that meshes with the 1-2 gear 44.

[0020] Referring to Figure 4, the first fin mechanism 40 further includes a rack portion 46 that meshes with the 1-3 gear 45 to convert rotational motion into linear motion, and a first link member 47 that serves as a link connecting the rack portion 46 to the fin body 30.

[0021] The gear provided on the first motor 41 is referred to as a first drive gear 41a for transmitting the driving force of the first motor 41.

[0022] The first motor 41 may be a motor other than a stepping motor.

[0023] When the first motor 41 is activated based on information from the temperature sensor or the operation of the occupant, the 1-1 gear 42, the first shaft member 43, the 1-2 gear 44, and the 1-3 gear 45 rotate. This causes the rack portion 46 to displace along the airflow direction, and the fin body 30 is displaced along the airflow direction via the first link member 47.

[0024] Referring to Fig. 2, the second fin mechanism 50 includes, for example, a second motor 51 which is a stepping motor that operates when energized, a 2-1 gear 52 which is a gear that rotates when the second motor 51 operates, a second shaft member 53 which is a shaft that passes through the 2-1 gear 52 and is rotatably supported by the housing 20, sector gears 54 which are fixed to both ends of the second shaft member 53 and which rotate when the 2-1 gear 52 rotates, and a 2-3 gear 55 which is a gear that meshes with the sector gear 54.

[0025] 5, the second fin mechanism 50 further includes a fin support portion 56 that meshes with the 2-3 gear 55 and is capable of supporting the fin body 30.

[0026] Hereinafter, the gear provided on the second motor 51 may be referred to as a drive gear 51a for transmitting the driving force of the motor.

[0027] The 2-3 gear 55 has two gears 55b and 55c (see FIG. 1 for 55c) mounted on one gear shaft 55a. The gear shaft 55a passes through the housing 20 and is rotatably mounted. One gear, 55c, is mounted outside the housing 20, and the other gear, 55b, is mounted inside the housing 20.

[0028] Referring to Figure 1, fin support portion 56 has connecting portion 56a that extends in the first direction and is connected to connected portion 31 in the normal mode. Note that if connected portion 31 is formed in a convex shape, connecting portion 56a may be formed in a concave shape so as to surround connected portion 31.

[0029] The fin support portion 56 also has pin-shaped support pins 56b and 56c inserted into the guide slit portions 24 and 25.

[0030] Referring to Fig. 5, the fin support portion 56 has a linear gear portion 56d that meshes with the 2-3 gear 55 and has teeth arranged in a straight line, and an arc gear portion 56e that meshes with the 2-3 gear 55 and has teeth arranged in an arc. The arc gear portions 56e are provided continuously from both ends of the linear gear portion 56d.

[0031] When second motor 51 is activated based on information from the temperature sensor or an operation by the occupant, 2-1 gear 52, sector gear 54, and 2-3 gear 55 rotate. This causes fin support portion 56 to displace in the second direction. When straight gear portion 56d is engaged with 2-3 gear 55, fin support portion 56 is displaced linearly in the second direction. When arc gear portion 56e is engaged with 2-3 gear 55, fin support portion 56 swings in an arc in the second direction, which is also the air blowing direction.

[0032] Referring to Figure 2, the air flow guide mechanism 60 has a second motor 51, a 2-1 gear 52, a second shaft member 53, a 3-2 gear 62 that is a gear fixed to the second shaft member 53, and a 3-3 gear 63 that is a gear that meshes with the 3-2 gear 62.

[0033] Referring to Figure 6, the air blower guide mechanism 60 further includes a 3-4 gear 64 that meshes with the 3-3 gear 63, a sector gear portion 65 that meshes with the 3-4 gear 64, a first guide fin 66 that is connected to the sector gear portion 65 and can swing around the connected portion, a guide link member 67 that is connected to the first guide fin 66, and a second guide fin 68 that is connected to the guide link member 67 and swings in conjunction with the first guide fin 66.

[0034] The second motor 51, the 2-1 gear 52, and the second shaft member 53 share the components of the second fin mechanism 50.

[0035] The 3-2 gear 62, the 3-3 gear 63, and the 3-4 gear 64 can be referred to as driven gears 62 to 64 that are driven by the drive gear 51a. Each of the driven gears 62 to 64 has a portion where no teeth are formed. The area where no teeth are formed of the 3-3 gear 63 is referred to as a first intermittent portion 63a, and the area where no teeth are formed of the 3-4 gear 64 is referred to as a second intermittent portion 64b.

[0036] Referring to Figure 3, the first guide fin 66 has an inner wall portion 66a extending along the tapered portion 33 from the narrow portion 23 to the air outlet 22, and a guide fin end surface portion 66b extending from the tip of the inner wall portion 66a and formed in an arc shape. The shape of the guide fin end surface portion 66b follows the shape of the peripheral portion of the air outlet 22. In the normal mode, the guide fin end surface portion 66b is stored in the movable wall storage portion 26.

[0037] The second guide fin 68 has an inner wall portion 68a extending along the tapered portion 33 from the narrow portion 23 to the air outlet 22, and a guide fin end surface portion 68b extending from the tip of the inner wall portion 68a and formed in an arc shape. The shape of the guide fin end surface portion 68b follows the shape of the peripheral portion of the air outlet 22. In the normal mode, the guide fin end surface portion 68b is stored in the movable wall storage portion 26.

[0038] Hereinafter, the first guide fin 66 and the second guide fin 68 may be collectively referred to as the guide fins 66, 68.

[0039] See FIG. 6. When the second motor 51 is activated based on information from the temperature sensor or the driver's operation while all gear teeth are engaged, the 2-1 gear 52, the 3-2 gear 62, the 3-3 gear 63, the 3-4 gear 64, and the sector gear portion 65 rotate. As the sector gear portion 65 rotates, the first guide fin 66 swings around the end of the inner wall portion 66a (the portion where the sector gear portion 65 is attached). The guide link member 67 connected to the end of the first guide fin 66 moves in conjunction with the first guide fin 66, causing the second guide fin 68 to swing. The second guide fin 68 swings around the end of the inner wall portion 68a. The first guide fin 66 and the second guide fin 68 swing while maintaining approximately the same distance.

[0040] When the 3-3 gear 63 rotates, the first intermittent portion 63a is displaced to a position closest to the 3-4 gear 64. At this time, the first intermittent portion 63a is positioned closest to the 3-4 gear 64. As a result, the first intermittent portion 63a and the second intermittent portion 64b face each other. When the first intermittent portion 63a and the second intermittent portion 64b face each other, the driving force of the 3-3 gear 63 is not transmitted to the 3-4 gear 64, and only the 3-3 gear 63 rotates. While the 3-4 gear 64 does not rotate, the sector gear portion 65 to the guide fins 66 and 68 do not displace. When the 3-3 gear 63 continues to rotate and a tooth of the 3-4 gear 64 meshes with a tooth adjacent to the second intermittent portion 64b, the 3-3 gear 63 to the guide fins 66 and 68 are displaced.

[0041] Also see Figure 5. The positions where the intermittent portions 63a, 64b are formed correspond to the positions where the straight gear portion 56d is formed. This makes it possible to prevent the guide fins 66, 68 from operating even while the second motor 51 is operating.

[0042] More specifically, while the 2-3 gear 55 is engaged with the straight gear portion 56d and linearly displacing the fin support portion 56 in the second direction, the guide fins 66, 68 do not operate. While the 2-3 gear 55 is engaged with the arc gear portion 56e and swinging the fin support portion 56, the guide fins 66, 68 operate.

[0043] Next, the operation of the air conditioning blowout device 10 will be described.

[0044] Please refer to Fig. 7A. Fig. 7A shows the air conditioning blower device 10 in normal mode. In normal mode, the fin body 30 is located between the narrow section 23 and the air outlet 22, and approximately in the middle of the flow path with respect to the second direction. In normal mode, the air to be blown is divided into upper and lower parts by the fin body 30, and the air is blown out from the air outlet 22 in the upper and lower directions.

[0045] The two split airflows are blown out from the air outlet 22 upward and downward, i.e., in directions away from each other, but because the air pressure in the central region (downstream of the arc surface 34) sandwiched between the two airflows drops, parts of the two airflows are drawn into the central region and bend toward each other. This causes the air to diffuse and can be blown over a wide area, including the central region.

[0046] Please refer to Figure 7B. Figure 7B shows the air conditioning blower device 10 in the air-blowing stop mode. When switching from the normal mode (see Figure 7A) to the air-blowing stop mode, the first fin mechanism 40 is activated to displace the fin body 30 upstream. When the fin body 30 abuts against the narrow portion 23, the flow path is blocked and air blowing is stopped. In other words, air is no longer blown out from the air outlet 22.

[0047] The fin body 30 can also be used at any position between the positions in FIG. 7A and FIG. 7B (between the most downstream position and the position where it abuts against the narrow portion 23).

[0048] Furthermore, as long as the fin body 30 can stop the airflow by blocking the flow path, the fin body 30 does not have to abut against the narrow portion 23. For example, the fin body 30 may abut against the upstream end of the first guide fin 66 and the upstream end of the second guide fin 68. It is sufficient that the fin body 30 abuts against and blocks the flow path when the fin body 30 is displaced from the normal mode toward the upstream side.

[0049] See Fig. 1. In the air-blowing stop mode, the connected part 31 slides upstream relative to the connecting part 56a. When the air-blowing stop mode is returned to the normal mode, the connected part 31 is connected to the connecting part 56a.

[0050] Please refer to Figure 8A. Figure 8A shows the air conditioning blower device 10 in downward-blowing mode. When switching from normal mode (see Figure 7A) to downward-blowing mode, the second fin mechanism 50 is operated to linearly displace the fin support portion 56 upward. The fin body 30 supported by the fin support portion 56 also displaces linearly upward. In downward-blowing mode, air is blown downward from between the underside of the fin body 30 and the first guide fin 66.

[0051] Also see Figure 6. When switching from normal mode to downward air-blowing mode, the guide fins 66, 68 do not operate even if the second motor 51 operates. When switching from normal mode to downward air-blowing mode, the first intermittent portion 63a and the second intermittent portion 64b are positioned opposite each other, and the driving force of the second motor 51 is not transmitted to the guide fins 66, 68.

[0052] Refer to FIG. 8B. FIG. 8B shows the air conditioning blower device 10 in the first center-blowing mode. When switching from the downward-blowing mode (see FIG. 8A) to the first center-blowing mode, the second fin mechanism 50 and the airflow guide mechanism 60 are activated to swing the fin support member 56 upward. The fin body 30 supported by the fin support member 56 also swings upward. A portion of the fin body 30 and the second guide fin 68 are housed inside the movable wall housing 26. Meanwhile, the inner wall portion 66a of the first guide fin 66 extends to an extension line from the upstream flow path. Air is blown out approximately horizontally from between the lower surface of the fin body 30 and the first guide fin 66. At this time, at least a portion of the guide fin end surface portion 66b is visible to the occupant and covers the area between the downstream end of the inner wall portion 66a of the guide fin 66 and the open end of the air outlet 22.

[0053] Please refer to Figure 9A. Figure 9A shows the air conditioning blower device 10 in upward air-blowing mode. When switching from normal mode (see Figure 7A) to upward air-blowing mode, the second fin mechanism 50 is operated to linearly displace the fin support portion 56 downward. The fin body 30 supported by the fin support portion 56 also displaces linearly downward. In upward air-blowing mode, air is blown upward from between the upper surface of the fin body 30 and the second guide fin 68.

[0054] Also see Figure 6. When switching from normal mode to upward air-blowing mode, the guide fins 66, 68 do not operate even if the second motor 51 operates. When switching from normal mode to upward air-blowing mode, the first intermittent portion 63a and the second intermittent portion 64b are positioned opposite each other, and the driving force of the second motor 51 is not transmitted to the guide fins 66, 68.

[0055] Refer to FIG. 9B. FIG. 9B shows the air conditioning blower device 10 in the second center-blowing mode. When switching from the upward-blowing mode (see FIG. 9A) to the second center-blowing mode, the second fin mechanism 50 and the airflow guide mechanism 60 are activated to swing the fin support member 56 downward. The fin body 30 supported by the fin support member 56 also swings downward. A portion of the fin body 30 and the first guide fin 66 are housed inside the movable wall housing 26. Meanwhile, the inner wall portion 68a of the second guide fin 68 extends to an extension line from the upstream flow path. Air is blown out approximately horizontally from between the upper surface of the fin body 30 and the second guide fin 68. At this time, at least a portion of the guide fin end surface portion 68b is visible to the occupant and covers the area between the downstream end of the inner wall portion 66a of the guide fin 66 and the open end of the air outlet 22.

[0056] The air conditioning blowout device 10 described above will be summarized below.

[0057] Referring to Fig. 3, first, air conditioning blowout device 10 has housing 20 into which air is blown and which has blowout outlet 22 formed at its downstream end with respect to the flow direction of the blown air, and fin body 30 provided so as to be displaceable inside housing 20. Housing 20 has narrow section 23 where the area of ​​the blown air is smaller than the area of ​​blowout outlet 22.

[0058] Also refer to Figure 1. Air outlet 22 has a substantially rectangular shape. If a direction parallel to long side 22a of air outlet 22 is defined as a first direction and a direction parallel to short side 22b, which is a side shorter than long side 22a, is defined as a second direction, fin body 30 is provided across the first direction, is located between air outlet 22 and narrow portion 23 in normal mode, and has tapered portion 33 whose width increases in the second direction from the upstream side to the downstream side.

[0059] 7A and 7B, when the state in which air is stopped from being blown out from air outlet 22 is defined as the air-blowing stopped mode (see FIG. 7B), a change from the normal mode (see FIG. 7A) to the air-blowing stopped mode is made by displacing fin body 30 toward the upstream side and bringing tapered portion 33 into contact with narrow portion 23 to close narrow portion 23.

[0060] When the area of ​​the air outlet 22 is smallest, the flow velocity is high at the air outlet 22, which is closest to the occupant, and the area where the air hits the occupant is also narrow, resulting in a strong wind hitting the occupant. Without narrowing the area of ​​the air outlet 22, a narrow section 23 is formed on the upstream side, and the air is divided into two between the narrow section 23 and the air outlet 22 by the fin body 30 (tapered shape 33). The two divided airflows blow out from the air outlet 22 in directions that move away from each other upward and downward, but because some of the two airflows are drawn into the central region, the wind is diffused and sent over a wide area including the central region. Therefore, the strength of the air hitting the occupant can be made just right, improving comfort.

[0061] Referring to Figure 3, second, in the first air conditioning blowing device 10, inner wall portions 66a, 68a are formed inside the housing 20, extending along the fin body 30 from the narrow portion 23 to the outlet 22. This allows the air to be smoothly guided from the narrow portion 23 to the outlet 22.

[0062] Third, in the first or second air-conditioning blower device 10, the width of the fin body 30 in the second direction is smaller than the width of the short side 22b (see FIG. 1) of the air outlet 22. This makes it possible to ensure a flow path from the narrow portion 23 to the air outlet 22 without narrowing it further.

[0063] Fourth, in any one of the first to third air volume blowing devices 10, the fin body 30 can be displaced upstream along the air blowing direction. The fin body 30 can also be used in any position between the positions shown in Figure 7A and Figure 7B (between the most downstream position and the position where it abuts against the narrow section 23).

[0064] Fifth, in the fourth air volume blowing device 10, the fin body 30 can be displaced upstream and abut against the inner wall of the flow path, thereby blocking the flow path and stopping the airflow. The airflow is controlled by moving upstream of the outlet and parallel to the airflow direction (approximately parallel to the line of sight), so it is possible to switch between the airflow state and the airflow stop state without changing the appearance.

[0065] See Fig. 4. Sixth, in any one of the first to fifth air conditioning blower devices 10, the first fin mechanism 40 has a first motor 41 that generates a rotational driving force when energized, and a rack portion 46 that converts the driving force of the first motor 41 into linear motion. The fin body 30 is connected to the rack portion 46. This allows the fin body 30 to be moved to a more accurate position.

[0066] See Fig. 5. Seventh, the air conditioning blower device 10 is any one of the first to sixth air conditioning blower devices 10, further comprising a second fin mechanism 50 for displacing the fin body 30 in a second direction. By displacing the fin body 30 in the second direction, the direction of air blowing can be adjusted.

[0067] Eighth, in the seventh air conditioning blower device 10, the second fin mechanism 50 has a second motor 51 that generates a driving force in a rotational direction when energized, and a fin support portion 56 that is displaced in the second direction by the driving force of the second motor 51 and can support the fin body 30. This allows the fin body 30 to be moved to a more accurate position.

[0068] Ninth, in the eighth air conditioning blower device 10, the fin support portion 56 has a linear gear portion 56d whose teeth are arranged linearly so as to displace linearly in the second direction, and an arc gear portion 56e whose teeth are arranged in an arc so as to displace in an arc in the second direction, and these linear gear portion 56d and arc gear portion 56e are formed continuously. This allows the fin body 30 to be linearly displaced in the second direction and to rotate. This allows air to be blown in a wider variety of directions.

[0069] See Fig. 6. Tenth, the air conditioning blower device 10 of any of the first to ninth embodiments further includes an air flow guide mechanism 60 that is displaceable toward the fin body 30 and that guides the direction of air blown out from the air outlet 22. The air flow guide mechanism 60 extends along the fin body 30 and has guide fins 66, 68 that are displaceable toward the fin body 30. By displacing the guide fins 66, 68, the air direction around the fin body 30 can be adjusted.

[0070] Eleventh, in the tenth air conditioning blower device 10, the downstream ends of the guide fins 66, 68 (see guide fin end surfaces 66b, 68b) have a shape that follows the peripheral edge of the air outlet 22 of the housing 20. This conceals the interior of the housing 20 in the central airflow mode, improving the appearance. Furthermore, it is possible to prevent dust or other objects from entering the interior of the movable wall storage section 26 and to prevent fingers from getting pinched.

[0071] Twelfthly, in the air conditioning blower device 10 of the tenth or eleventh aspect, the air blow guide mechanism 60 includes a second motor 51 as a drive source, and the guide fins 66, 68 are swung by the drive force of the second motor 51. The positions of the guide fins can be adjusted more precisely.

[0072] Also see Figure 6. Thirteenth, in the air conditioning blower device 10 of any of the tenth to twelfth aspects, the air flow guide mechanism 60 has a second motor 51 as a drive source, a drive gear 51a that rotates when driven by the second motor 51, and driven gears 62 to 64 that can rotate when the drive gear 51a rotates.
