  According to 1st invention, while introducing the air ventilated from the ventilation source from the one side in the cylinder length direction of the said air blowing part via the 1st duct with respect to the inside of a cylindrical air blowing part, It introduces from the other side (opposite side) in the cylinder length direction of the air blowing part via the second duct, and the air volume control means controls the air flow rate from both sides in the cylinder length direction with respect to the inside of the air blowing part. Since it is controlled individually, it is possible to adjust the direction of the wind blown to the outside from the air outlet while colliding at the internal location corresponding to the air outlet in the air outlet in the cylinder length direction of the air outlet. it can. Therefore, it is possible to realize a blower capable of adjusting the wind direction with a simple structure without having a fin for controlling the wind direction at the air outlet.

  Further, according to the first invention, the air blowing portion and the air passage portion for passing air to one side in the cylinder length direction of the air blowing portion are arranged in parallel, and both are integrally provided to constitute the blowing unit. Since it did in this way, the rigidity of these air blowing parts and an air passage part can be improved compared with the case where an air blowing part and an air passage part are each provided separately. Accordingly, the wall thickness of the blowing unit, that is, the thickness of the peripheral wall of the air blowing portion and the air passage portion can be formed relatively thin while ensuring a desired rigidity in the air blowing portion and the air passage portion. Thus, the weight of the blower can be reduced.

Since the airflow and the airflow flowing to the air outlet along the inner peripheral surface of the air outlet portion around the other side in the circumferential direction of the air outlet portion are separated, by rotating the movable partition plate, The direction of the blowing air can be changed in a direction orthogonal to the cylinder length direction of the air blowing portion.

  That is, the two air currents separated by the movable partition plate flow in the opposite directions to the air outlet along the inner peripheral surface of the air outlet, and merge while colliding at the air outlet and the vicinity thereof. Is blown out from the blowing section. The longer the distance of the portion of the inner peripheral surface of the air blowing portion along the air flow from the movable partition plate to the air outlet, the higher the directivity when blowing out from the air outlet, and The space through which the air flows increases and the air volume increases accordingly. From this, by moving the partition position of the movable partition plate by the rotation operation means, the balance of the blowing strength by these two air currents is changed, and the direction of the wind blown from the blowout port is changed to the tube length direction of the air blowing portion. It can be changed in the orthogonal direction. Therefore, it is possible to specifically realize a simple air blower according to the fourth invention.

  According to the sixth invention, after the air introduced into the air blowing part is introduced into the inside from both open ends of the inner cylinder rotatably accommodated in the air blowing part, the air is introduced into the peripheral wall of the inner cylinder. A tube of the air blowing portion is configured to be blown out from the blowing port of the air blowing portion through a certain internal blowing port, and to form a projecting port portion protruding outward from the housing portion that houses the inner cylindrical body in the air blowing portion. Since the pair of opposing walls facing each other in the direction perpendicular to the length direction is configured to extend from the housing portion side toward the air outlets between the projecting ends of these opposing walls, the inner cylinder body The direction of the wind blown out from the blowout port can be changed in a direction orthogonal to the cylinder length direction of the air blowout portion.

  That is, the direction of the inner blowout port of the inner cylinder inside the air blowing section is such that the inner cylinder body is rotated by the rotation operation means, and the front state is directed straight to the blowout port of the air blowing section. It is possible to switch between a first inclined state inclined toward one opposing wall side in the projecting opening portion rather than a state and a second inclined state inclined toward the other opposing wall side in the protruding opening portion rather than the front state. When the inner cylinder is in the front state, the air blown out from the internal blow-out port is blown out straight in the front direction of the blow-out port through the blow-out port of the air blowing unit. Further, when the inner cylinder is in the first inclined state and when it is in the second inclined state, the air blown out from the internal blow-out ports is blown from the air blowing portions along the inner surfaces of different opposing walls. It is guided to the outlet and blows out from the outlet in the direction intersecting with each other. From this, the direction of the wind blown from the outlet of the air outlet through the inner outlet is changed in a direction orthogonal to the cylinder length direction of the air outlet by changing the direction of the inner outlet of the inner cylinder by the rotation operation means. Can be changed. Therefore, it is possible to specifically realize a simple air blower according to the fourth invention.

  The wind direction adjusting mechanism 57 supports a rotating shaft 59 inserted through the inner center of the accommodating portion 23 in the air blowing portion 19, a movable bearing member 61 that supports the left end portion of the rotating shaft 59, and a right end portion of the rotating shaft 59. A fixed plate member 63, a movable partition plate 65 rotatably supported on the rotary shaft 59 between a portion of the fixed plate member 63 that supports the rotary shaft 59 and the movable bearing member 61, and the movable partition plate 65 Rotation operation means 91 for operating the rotation operation. Among these, the rotation shaft 59, the movable bearing member 61, and the movable partition plate 65 are provided inside the air blowing portion 19 and correspond to the blowout port 17, and the direction of the wind blown out from the blowout port 17 in the vertical direction. A wind direction control member 58 to be changed is configured.

  The rotating shaft 59 has a small diameter portion 59a that constitutes both ends, and a large diameter portion 59b that constitutes a portion between the small diameter portions 59a. The left small diameter portion 59 a of the rotating shaft 59 is a portion supported by the movable bearing member 61, and the right small diameter portion 59 a is a portion supported by the fixed plate member 63. The large-diameter portion 59b of the rotating shaft 59 is formed to be slightly larger in diameter than the small-diameter portion 59a and has an end face that faces each small-diameter portion 59a.

  The movable bearing member 61 has a cylindrical holding portion 67 into which the left small diameter portion 59a of the rotating shaft 59 is inserted and fixed, and a circle arranged with the outer peripheral surface in contact with the inner peripheral surface of the air blowing portion 19. An annular outer ring portion 69, and a plurality of (four in the example shown in FIG. 3) connecting portions 71 that connect the holding portion 67 and the outer ring portion 69, and the holding portion 67, the outer ring portion 69, and the connecting portion. 71 is integrally formed to form a wheel-like shape as a whole.

  Each connecting portion 71 is formed in a thin small plate shape extending straight from the holding portion 67 in the radial direction of the outer ring portion 69. The plurality of connecting portions 71 are arranged so as to extend in four directions from the holding portion 67 in the up, down, left, and right directions, for example, at intervals. The movable bearing member 61 can send conditioned air to the inner center side of the air blowing portion 19 through the adjacent connecting portions 71 in this way. A gear portion 72 having gear teeth is provided on the outer peripheral surface of the outer ring portion 69 of the movable bearing member 61 over the entire circumference.

  The movable partition plate 65 is formed in a substantially rectangular strip shape extending along the large-diameter portion 59b of the rotation shaft 59, and at a position corresponding to the outlet 17 in the air outlet 19, the air outlet 19 The interior is partitioned in a radial direction from the rotary shaft 59 to the inner peripheral surface 23 a of the air blowing portion 19. The outer end of the movable partition plate 65 located on the inner peripheral surface 23 a side of the air blowing portion 19 is in contact with the inner peripheral surface 23 a of the air blowing portion 19 or slightly from the inner peripheral surface 23 a of the air blowing portion 19. It is spaced apart and close to the inner peripheral surface 23a.

  The movable partition plate 65 is formed integrally with the rotary shaft 59, and in a direction in which the outer end runs along the inner peripheral surface 23a of the air blowing portion 19 around the rotary shaft 59 as the rotary shaft 59 rotates. It is possible to rotate, and it is possible to move the partition position inside the air blowing part 19 by rotating together with the rotating shaft 59. Thereby, the air blower 5 can change the direction of the wind which blows off from the blower outlet 17 in an up-down direction.

  That is, the conditioned air introduced into the air blowing portion 19 through at least one of the rear duct 15B and the front duct 15F is moved along the inner peripheral surface of the air blowing portion 19 by the movable partition plate 65. Thus, it is separated into a lower airflow flowing clockwise as viewed from the right side of the air blowing portion 19 and an upper airflow flowing counterclockwise. The lower airflow passes through a portion from the lower side to the rear side of the inner peripheral surface of the air blowing portion 19 and flows to the blowout port 17 obliquely upward along the inner surface 33a of the lower inclined wall 33. On the other hand, the upward airflow passes through a portion from the upper side to the rear side of the inner peripheral surface of the air blowing portion 19 and flows to the outlet 17 obliquely downward along the inner surface 31a of the upper inclined wall 31. These two air currents merge while colliding at and near the air outlet 17, and the merged air is blown out from the air outlet 17.

  The two airflows separated by the movable partition plate 65 are blown out from the blowout port 17 as the distance of the portion along the inner peripheral surface of the air blowing portion 19 along the airflow from the movable partition plate 65 to the blowout port 17 is longer. In addition to the increased directivity, the space in which the airflow flows increases, and the air volume increases accordingly. From this, by moving the partition position of the movable partition plate 65 by the rotation operation means 91, the balance of the blowing strength by these two airflows can be changed, and the direction of the wind blown from the outlet 17 can be changed in the vertical direction. it can.

  The rotation operation means 91 is installed at the left end portion of the air blowing portion 19 on the upper side of the blowing unit 11, and is a driven gear that meshes with the gear portion 72 of the movable bearing member 61 through a hole 60 formed in the peripheral wall of the air blowing portion 19. 95 and a motor 93 provided with a drive gear 93a meshing with the driven gear 95 on the output shaft. The motor 93 is a motor that can switch the rotation direction between forward rotation and reverse rotation. The movable partition plate 65 drives the motor 93 so that the rotational power of the drive gear 93a is transmitted to the movable bearing member 61 through the driven gear 95 and further to the rotary shaft 59, so that the rotary shaft 59 also returns. Rotate. The rotation operation means 91 executes driving of the motor 93 and switching of the rotation direction based on an input signal for setting a wind direction from a wind direction input means such as an occupant operation panel provided on the instrument panel P or a dial. The rotating operation of the movable partition plate 65 is operated.

  The fixed plate member 63 includes a pair of blocking plates 73 and 75 that face each other in the left-right direction, and a fixed partition plate 77 provided between the pair of blocking plates 73 and 75. A hemispherical bearing projection piece 79 is provided at the front end of the right closing plate 75 so as to protrude forward in a side view. This bearing protrusion 79 has an insertion hole 80 through which the small diameter portion 59a on the right side of the rotating shaft 59 is inserted.

  The fixed plate member 63 supports the rotary shaft 59 rotatably by inserting the right small diameter portion 59 a of the rotary shaft 59 into the insertion hole 79. A nylon washer 83 is interposed between the bearing protrusion 79 of the fixed plate member 63 and the end surface of the large-diameter portion 59b of the rotating shaft 59. As a result, the friction between the bearing protrusion 79 and the rotary shaft 59 is reduced, and the rotary shaft 59 is smoothly rotated.

  In addition, attachment protrusions 81 that protrude outward from the fixed plate member 63 are provided at the rear ends of the pair of closing plates 73 and 75, respectively. That is, a mounting protrusion 81 protruding leftward is provided at the rear end of the left closing plate 73, and a mounting protrusion 81 protruding rightward is provided at the rear end of the right closing plate 75. . The fixed plate member 63 fits both the mounting protrusions 81 into the mounting holes 35 provided in the pair of left and right side walls 27 and 29 in the protruding port portion 25 of the air blowing portion 19. It is fixed.

  Each of the blocking plates 73 and 75 has a shape corresponding to the side walls 27 and 29 of the projecting opening 25 in the air blowing portion 19 and projecting toward the rotation shaft 59 on the front side of the side walls 27 and 29. The side end surface of the mouth portion 25 is closed in front of the rotation shaft 59. As a result, the conditioned air introduced from the left and right sides into the air blowing portion 19 does not flow directly into the protruding port portion 25 and is sent to the protruding port portion 25 after passing through the accommodating portion 23. The above-described wind direction control in the vertical direction by the rotating operation of the movable partition plate 65 can be executed accurately and reliably.

  Each of the closing plates 73 and 75 is a front end surface with which the movable partition plate 65 contacts at a predetermined rotation angle, specifically, upper front end surfaces 73a and 75a that are located above the rotation shaft 59 and face obliquely upward. The lower front end surfaces 73b and 75b are positioned below the rotating shaft 59 and face obliquely downward. The rotation range of the movable partition plate 65 is limited to a range between the upper front end surfaces 73a and 75a and the lower front end surfaces 73b and 75b of the closing plates 73 and 75 in front of the closing plates 73 and 75.

  The fixed partition plate 77 is formed in a strip shape extending along the rotation shaft 59 and is disposed in a horizontal posture between the rotation shaft 59 and the outlet 17 in a state of being spaced apart from the rotation shaft 59 with a slight gap. In addition, a space in which two airflows (upper airflow and lower airflow) separated by the movable partition plate 65 described above flow is partitioned on the front side of the rotation shaft 59. Both ends of the fixed partition plate 77 are integrally connected to the corresponding blocking plates 73 and 75. In other words, the pair of closing plates 73 and 75 are connected to each other via the fixed partition plate 77.

  The positional relationship between the front end of the fixed partition plate 77 facing the air outlet 17 and the air outlet 17 is as follows. The distance between both vertical edges of the air outlet 17 (opening width in the vertical direction) a is as shown in FIG. And the distances b and c between the upper and lower edges of the air outlet 17 and the rear end of the fixed partition plate 77 are equal to each other. That is, the straight line connecting the upper and lower end edges of the air outlet 17 and the straight line connecting the upper and lower end edges of the air outlet 17 and the rear end of the fixed partition plate 77 are viewed from the cylinder length direction of the air outlet 19. Draw an equilateral triangle.

  As a result, it is possible to suppress the unstable wind direction control in the vertical direction due to the rotation operation of the movable partition plate 65 described above due to the fixed partition plate 77 being too far from the outlet 17. In addition, the fixed partition plate 77 is too long to reach the air outlet 17 and obstruct the air blown out from the air outlet 17 without causing a reduction in the amount of air flow. Thereby, it is possible to achieve both prevention of turbulent flow in front of the air outlet 17 inside the air outlet 19 and securing of the amount of air blown from the air outlet 17.

  The wind direction control member 58 is installed in the air blowing portion 19 with a laminated ring 85 interposed between the left end face and is attached to the air blowing portion 19 by a fixed plate member 63. The laminated ring 85 has a structure in which a low-friction ring 87 made of nylon and a cushioning buffer ring 89 made of foamed resin are laminated. This laminated ring 85 is provided with the low friction ring 87 in contact with the movable bearing member 61, and buffers the play caused by manufacturing errors in the state where the wind direction control member 58 is accommodated in the air blowing part 19. Absorb with ring 89 to prevent.

  The air volume control unit 13 is connected to each open end of the rear duct 15B and the front duct 15F on the side opposite to the connection side with the blowing unit 11. The air volume control unit 13 includes a damper (not shown) for adjusting the air flow rate to the rear duct 15B and the front duct 15F for each duct 15. And the air volume control part 13 is based on the input signal which sets the wind direction from the said wind direction input means, The ventilation volume with respect to the rear side duct 15B and the front side duct 15F which are ventilated by the blower 7, and with respect to the inside of the air blowing part 19 as a result The air volume from the left side and the air volume from the right side are individually controlled.

  In the air blower 5 having the above-described configuration, by rotating the movable partition plate 65 by the rotation operation means 91 and moving the partition position inside the air blowing portion 19 by the movable partition plate 65, The direction of the wind blown from the blowout port 17 is controlled by the airflow control unit 13 with the airflow control unit 13 controlling the airflow amount from the rear duct 15B to the blowout unit 11 and the airflow amount from the front duct 15F. Can be changed in the horizontal direction.

  Below, the wind direction control of the air blower 5 which concerns on this embodiment is demonstrated, referring FIG.7 and FIG.8. FIGS. 7A to 7E are longitudinal sectional views of the air blowing portion 19 showing an example of the valuation for controlling the wind direction in the vertical direction in the blower 5. FIGS. 8A to 8E are cross-sectional views of the air blowing unit 19 showing an example of the valuation of the wind direction control in the left-right direction in the blower 5.

  In addition, the arrow shown as a continuous line in these Fig.7 (a)-(e) and Fig.8 (a)-(e) has shown the flow of the conditioned air inside the air blowing part 19. FIG. Moreover, the arrow shown with a dashed-dotted line in FIG. 8 (a), (b) has shown the compressed air which stayed in the inside of the air blowing part 19. FIG. 8A to 8E, only the peripheral wall of the air blowing portion 19 is shown, and other configurations such as the wind direction control member 58 are omitted.

  First, with reference to FIGS. 7A to 7E, an operation for controlling the direction of the wind blown from the blower outlet 17 of the blower 5 in the vertical direction will be described.

  When an input signal for setting the wind direction to the most upward direction is input from the wind direction input means, the blower 5 drives the motor 93 of the rotation operation means 91 as necessary to move the movable partition plate 65 to the closing plate 73, As shown in FIG. 7 (a), the outer end of the movable partition plate 65 is set to be in a state of being directed obliquely rearward on the upper side by rotating to a position where it contacts the upper front end surfaces 73a and 75a of 75.

  In this case, the conditioned air introduced into the air blowing part 19 from at least one of the rear duct 15B and the front duct 15F is caused by the pressure difference between the inside and the outside of the air blowing part 19. The inner surface of the lower inclined wall 33 passes through a portion from the front side to the lower side of the inner peripheral surface 23a of the accommodating portion 23 in a clockwise direction when the air blowing portion 19 is viewed from the right side along the inner peripheral surface 19 It flows to the blower outlet 17 diagonally upward along 33a, and blows off diagonally upward as it is from the blower outlet 17 to the exterior (vehicle interior). In this way, the direction of the wind blown out from the blower outlet 17 is directed most upward.

  In addition, when an input signal for setting the wind direction to the most downward direction is input from the wind direction input unit, the blower 5 drives the motor 93 of the rotation operation unit 91 as necessary so that the movable partition plate 65 is closed. As shown in FIG. 7 (b), the outer end of the movable partition plate 65 is set in a state of facing the lower oblique direction by rotating it to a position where it contacts the lower front end faces 73b, 75b.

  In this case, the conditioned air introduced into the air blowing part 19 from at least one of the rear duct 15B and the front duct 15F is caused by the pressure difference between the inside and the outside of the air blowing part 19. The inner surface 31a of the upper inclined wall 31 passes through a portion from the front side to the upper side of the inner peripheral surface 23a of the housing portion 23 in a counterclockwise direction when the air blowing portion 19 is viewed from the right side along the inner peripheral surface 19 The air then flows obliquely downward to the air outlet 17 and is blown out obliquely downward from the air outlet 17 to the outside. In this way, the direction of the wind blown out from the blower outlet 17 is directed downward most.

  Also, when an input signal for setting the wind direction to the center in the vertical direction is input from the wind direction input unit, the blower 5 drives the motor 93 of the rotation operation unit 91 as necessary to move the movable partition plate 65. Is rotated to a position in a horizontal position in front of the fixed partition plate 77, so that the outer end of the movable partition plate 65 is directed in a direction opposite to the outlet 17 as shown in FIG. To do.

  In this case, the conditioned air introduced into the air blowing part 19 from at least one of the rear duct 15B and the front duct 15F is blown out by the movable partition plate 65 as viewed from the right side of the air blowing part 19. Airflow flowing clockwise along the inner peripheral surface of the portion 19, that is, obliquely upward along the inner surface 33 a of the lower inclined wall 33 via a portion from the front side to the lower side of the inner peripheral surface 23 a of the housing portion 23. Toward the upper side of the inner peripheral surface 23a of the housing portion 23, that is, the lower airflow flowing toward the air flow and the airflow flowing counterclockwise along the inner peripheral surface of the air blowing portion 19 when viewed from the right side of the air blowing portion 19. Is separated into an upward airflow that flows obliquely downward along the inner surface 31a of the upper inclined wall 31.

  These two airflows flow in opposite directions to the air outlet 17 along the inner peripheral surface of the air outlet 19 and merge while colliding at the air outlet 17 and the vicinity thereof, and the combined conditioned air is the air outlet 17. From outside. At this time, the blasting strength of the conditioned air by the upper airflow and the lower airflow separated by the movable partition plate 65 is such that the partition position of the movable partition plate 65 in the air blowing portion 19 is half the upper and lower portions inside the air blowing portion 19. Therefore, the conditioned air introduced from the duct 15 into the air blowing portion 19 is blown out from the blowout port 17 toward the center in the vertical direction. In this way, the direction of the wind blown from the blower outlet 17 is directed to the center in the vertical direction.

  In addition, when an input signal for setting the wind direction slightly upward is input from the wind direction input unit, the blower 5 drives the motor 93 of the rotation operation unit 91 as necessary so that the movable partition plate 65 is closed. As shown in FIG. 7 (d), the outer end of the movable partition plate 65 is set to be in a state of being directed obliquely upward on the upper side by rotating to the position just opposite to the lower front end faces 73b, 75b of 73, 75.

  Also in this case, the conditioned air introduced into the air blowing portion 19 from at least one of the rear duct 15B and the front duct 15F is separated into an upper airflow and a lower airflow by the movable partition plate 65, These two air currents merge while colliding at the air outlet 17 and the vicinity thereof, and are blown out from the air outlet 17. At this time, the partition position of the movable partition plate 65 inside the air blowing portion 19 is such that the space where the upper airflow flows is relatively narrow and the space where the lower airflow flows is relatively wide inside the air blowing portion 19. In the partitioning position. From this, since the blast strength of the conditioned air by the lower airflow is stronger than the blast strength of the conditioned air by the upper airflow, the conditioned air introduced from the duct 15 into the air blowing portion 19 is blown out by the lower airflow. It is pushed by the wind flowing obliquely upward toward 17 and is blown out upward and downward from the air outlet 17. Thus, the direction of the wind blown out from the blowout port 17 is directed slightly upward.

  In addition, when an input signal for setting the wind direction slightly downward is input from the wind direction input unit, the blower 5 drives the motor 93 of the rotation operation unit 91 as necessary so that the movable partition plate 65 is closed. As shown in FIG. 7 (e), the outer end of the movable partition plate 65 is directed obliquely forward to the lower side by rotating it to a position just opposite to the upper front end faces 73a, 75a of 73, 75.

  Also in this case, the conditioned air introduced into the air blowing portion 19 from at least one of the rear duct 15B and the front duct 15F is separated into an upper airflow and a lower airflow by the movable partition plate 65, These two air currents merge while colliding at and near the air outlet 17 and are blown out from the air outlet 17. At this time, the partition position of the movable partition plate 65 inside the air blowing portion 19 is such that the space where the upper airflow flows is relatively wide and the space where the lower airflow flows is relatively narrow inside the air blowing portion 19. In the partitioning position. Therefore, the conditioned air blowing strength by the upper airflow is stronger than the conditioned air blowing strength by the lower airflow, so that the conditioned air introduced from the duct 15 into the air blowing portion 19 is blown out by the upper airflow. It is pushed by the wind flowing diagonally downward toward 17 and is blown out from the air outlet 17 downward. Thus, the direction of the wind blown out from the blowout port 17 is slightly directed downward.

  Next, an operation for controlling the direction of the wind blown from the blower outlet 17 of the blower 5 in the left-right direction will be described with reference to FIGS.

  When the input signal for setting the wind direction to the leftmost direction is input from the wind direction input unit, the blower 5 eliminates the amount of air blown to the rear duct 15B by the air volume control unit 13, that is, blows air to the rear duct 15B. In addition, the conditioned air from the air conditioner 3 is blown only to the front duct 15F, with the blast volume for the front duct 15F set as a predetermined blast volume corresponding to the wind intensity level set for the occupant.

  In this case, the conditioned air introduced from the front duct 15F into the air blowing portion 19 flows from the right to the left inside the air blowing portion 19 as shown in FIG. Due to the pressure difference between the inside and the outside of 19, the flow is changed to an oblique left flow directed toward the blowout port 17 toward the blowout port 17, and blown obliquely leftward from the blowout port 17 to the outside. In this way, the direction of the wind blown out from the blower outlet 17 is directed to the left most.

  Further, when an input signal for setting the wind direction to the rightmost direction is input from the wind direction input unit, the blower 5 eliminates the amount of air blown to the front duct 15F by the air volume control unit 13, that is, blows air to the front duct 15F. In addition, the conditioned air from the air conditioner 3 is blown only to the rear duct 15B with the amount of blown air to the rear duct 15B as a predetermined amount of blown air according to the wind intensity level set for the occupant.

  In this case, the conditioned air introduced from the rear duct 15B into the air blowing portion 19 flows from the left to the right inside the air blowing portion 19 as shown in FIG. Due to the pressure difference between the inside and the outside of the part 19, the flow is changed to a flow to the right and directed toward the blowout port 17, and blown rightward and obliquely from the blowout port 17 to the outside. In this way, the direction of the wind blown out from the blower outlet 17 is directed to the rightmost.

  In addition, when an input signal for setting the wind direction to the center in the left-right direction is input from the wind direction input unit, the air blower 5 is controlled by the air volume control unit 13 with respect to the inside of the air blowing unit 19. The amount of air blown to the rear duct 15B and the front duct 15F so that the air blowing strength of the conditioned air introduced from the left side of 19 and the air blowing strength of the conditioned air introduced from the right side of the air blowing portion 19 are at the same level. Set.

  In this case, the conditioned air introduced from the both sides into the air blowing part 19 via the rear duct 15B and the front duct 15F, respectively, as shown in FIG. 8C, the inside and outside of the air blowing part 19 Are both guided to the outlet 17 side and blown out from the outlet 17 to the outside. In the process, the conditioned air introduced from the left side into the air blowing part 19 through the rear duct 15B and the conditioned air introduced from the right side into the air blowing part 19 through the front duct 15F are: It merges while colliding with the blower outlet 17 and its vicinity. At this time, since the conditioned air introduced from the rear duct 15B and the conditioned air introduced from the front duct 15F have the same level of air blowing, they are directed from the outlet 17 to the outside toward the center in the left-right direction. Blown out. In this way, the direction of the wind blown out from the outlet 17 is directed to the center in the left-right direction.

  In addition, when an input signal for setting the wind direction to be slightly leftward in the left-right direction is input from the wind direction input unit, the air blower 5 is controlled by the air volume control unit 13 with respect to the inside of the air blowing unit 19. The air flow rate for the rear duct 15B and the front duct 15F is set so that the air blowing strength of the conditioned air introduced from the right side of 19 is stronger than the air blowing strength of the conditioned air introduced from the left side of the air blowing portion 19. Set.

  Also in this case, the conditioned air introduced from the both sides into the air blowing part 19 through the rear duct 15B and the front duct 15F, as shown in FIG. And the outside are both guided to the outlet 17 side, merged while colliding at the outlet 17 and the vicinity thereof, and blown out from the outlet 17. At this time, since the blowing strength of the conditioned air introduced into the air blowing portion 19 from the right side is stronger than the blowing strength of the conditioned air introduced from the left side into the air blowing portion 19, the rear duct 15B and the front side The conditioned air introduced from the duct 15F into the air blowing part 19 is pushed by the conditioned air introduced from the right side into the air blowing part 19 and blown out from the blower outlet 17 to the outside in a leftward and rightward manner. In this way, the direction of the wind blown out from the blowout port 17 is directed slightly to the left.

  In addition, when an input signal for setting the wind direction to be slightly rightward in the left-right direction is input from the wind direction input unit, the air blower 5 is controlled by the air volume control unit 13 with respect to the inside of the air blowing unit 19. The amount of air blown to the rear duct 15B and the front duct 15F is set so that the blast strength of conditioned air introduced from the left side of 19 is stronger than the blast strength of conditioned air introduced from the right side of the air blowing portion 19. Set.

  Also in this case, the conditioned air introduced from the both sides into the air blowing part 19 through the rear duct 15B and the front duct 15F, as shown in FIG. And the outside are both guided to the outlet 17 side, merged while colliding at the outlet 17 and the vicinity thereof, and blown out from the outlet 17. At this time, since the blowing strength of conditioned air introduced from the left side into the air blowing portion 19 is stronger than the blowing strength of conditioned air introduced from the right side into the air blowing portion 19, the rear duct 15B and the front side The conditioned air introduced from the duct 15F into the air blowing portion 19 is pushed by the conditioned air introduced from the left side into the air blowing portion 19 and blown rightward from the blowout port 17 to the outside. In this way, the direction of the wind blown from the blowout port 17 is directed slightly to the right.

  As described above, the air blower 5 adjusts the direction of the wind blown from the outlet 17 by operating the rotation operation of the movable partition plate 65 by the rotation operation means 91, and the rear air duct control unit 13 controls the rear duct. By individually controlling the amount of air blown to 15B and the front duct 15F, the direction of the wind blown from the blowout port 17 can be adjusted in the left-right direction. Further, according to the combination of the wind direction control in the up-down direction and the left-right direction, the direction of the wind blown from the blowout port 17 is an intermediate direction between the up-down direction and the left-right direction, that is, upper left direction, upper right direction, lower left direction, and lower right direction. Can also be adjusted.

-Effect of Embodiment 1-
According to the first embodiment, the blowout port 17 that blows out conditioned air does not have the fins for controlling the wind direction, and the direction of the wind blown out from the blowout port 17 can be adjusted vertically and horizontally with a simple structure. Thereby, the air blowing unit 5 and the air-conditioning unit 1 provided with the air blower 17 can be realized, and the design of the instrument panel P incorporating the air-conditioning unit 1 can be improved.

  Further, according to the first embodiment, the air blowing portion 19 and the air passage portion 21 through which air is passed to the right side of the air blowing portion 19 are arranged in parallel, and the air blowing portion 11 having a novel structure in which both are integrally provided is provided. Therefore, the rigidity of the air blowing portion 19 and the air passage portion 21 can be increased as compared with the case where the air blowing portion 19 and the air passage portion 21 are separately provided separately. Thereby, the wall thickness of the blowing unit 11, that is, the thickness of the peripheral wall of the air blowing portion 19 and the air passage portion 21 can be formed relatively thin while ensuring a desired rigidity in the air blowing portion 19 and the air passage portion 21. Further, it is possible to reduce the weight of the blow-out unit 11 and thus to reduce the weight of the blower 5.

  And according to this Embodiment 1, the front side duct 15F is connected to the air passage part 21 from the left side with the rear side duct 15B with respect to the blowing unit 11, and the right side is inserted into the air blowing part 19 via this air passage part 21. Therefore, it is not necessary to draw the front duct 15F to the right position of the air blowing portion 19.

<< Embodiment 2 of the Invention >>
The air blower 5 according to the second embodiment is different from the first embodiment in the wind direction control member 58. In addition, in this embodiment, since the structure of the wind direction control member 58 differs from the said Embodiment 1, it is comprised similarly to the said Embodiment 1 about the air blower 5 and the air conditioning unit 1 provided with this, Therefore The wind direction from which a structure differs Only the control member 58 will be described, and the same components will be left to the description of the first embodiment based on FIGS. 1 to 8, and detailed description thereof will be omitted.

  FIG. 9 is an exploded perspective view of the blowing unit 11 constituting the blower 5 according to the second embodiment. FIG. 10 is a view corresponding to FIG. In the first embodiment, the wind direction control member 58 is composed of the rotating shaft 59, the movable bearing member 61, and the movable partition plate 65. However, the wind direction control member 58 of the blower device 5 according to the present embodiment is an air outlet. This is a cylindrical inner cylinder having a double cylinder structure with the portion 19.

  Both ends of the inner cylinder 58 are open, and the conditioned air introduced into the air blowing portion 19 is introduced into the inside as it is from the open end. An inner air outlet 97 for blowing air introduced into the inside from both open ends inside the air blowing portion 19 is provided in a central portion of the peripheral wall of the inner cylinder body 58 in the rear cylinder length direction. The internal air outlet 97 is formed in a flat shape (slit shape) that extends in the cylinder length direction of the inner cylinder 58, that is, in the left-right direction. A gear portion 99 having gear teeth is provided on the outer peripheral surface of the left end portion of the inner cylindrical body 58 over the entire circumference.

  In the inner cylinder 58, as shown in FIG. 5, one end edge (the lower end edge in the illustrated example) of the internal air outlet 97 is positioned on the opening center line of the air outlet 17 of the air outlet 19. On the opening center line of the air outlet 17 of the air outlet 19 among the distance a between the both ends in the vertical direction of the outlet 17 (opening width in the vertical direction) a and both ends of the outlet 17 and the internal outlet 97 The distances b and c between the edge located at the same distance are equal. That is, a straight line connecting both end edges in the vertical direction of the air outlet 17 of the air outlet 19, and both edges of the air outlet 17 and an edge located on the opening center line of the air outlet 17 among the internal air outlets 97. The connecting straight line is a regular triangle as seen from the cylinder length direction of the air blowing part 19. Thereby, it is possible to achieve both prevention of turbulent flow in front of the air outlet 17 inside the air outlet 19 and securing of the amount of air blown from the air outlet 17.

  The gear 99 of the inner cylinder 58 is engaged with the driven gear 95 of the rotation operating means 91, and the motor 93 is driven so that the rotational power of the drive gear 93 a of the motor 93 is transmitted via the driven gear 95. Is transmitted to the inner cylinder 58, and the inner cylinder 58 can be rotated. The rotation operation unit 91 is configured to operate the rotation operation of the inner cylinder 58 by driving the motor 93 and switching the rotation direction based on an input signal for setting the wind direction from the wind direction input unit.

  In the air blower 5 having the above-described configuration, the direction of the wind blown from the air outlet 17 of the air outlet 19 through the internal air outlet 97 by rotating the inner cylinder 58 by the rotation operation means 91 and changing the direction of the internal air outlet 97. Is changed in the vertical direction, and the air volume control unit 13 controls the air volume from the rear duct 15B and the air volume from the front duct 15F with respect to the air outlet unit 11, so that the direction of the wind blown from the air outlet 17 is changed. It can be changed in the horizontal direction.

  Below, the wind direction control of the air blower 5 which concerns on this embodiment is demonstrated, referring FIG. FIGS. 11A to 11E are longitudinal sectional views of the air blowing unit 19 showing an example of the valuation of the vertical wind direction control in the blower 5 according to the present embodiment. Since the wind direction control in the left-right direction is the same as that in the first embodiment, detailed description thereof is omitted.

  When the input signal for setting the wind direction to the most downward direction is input from the wind direction input unit, the blower 5 rotates the inner cylinder 58 by driving the motor 93 of the rotation operation unit 91 as necessary. As shown in FIG. 11 (a), the entire internal air outlet 97 is directed toward the inclined wall 31 on the upper side of the projecting opening 25.

  In this case, the conditioned air introduced into the inner cylinder 58 from at least one of the rear duct 15B and the front duct 15F is caused by a difference in atmospheric pressure between the inside of the inner cylinder 58 and the outside of the air outlet 19. After being blown out from the internal air outlet 97 toward the upper inclined wall 31, it flows obliquely downward along the inner surface 31 a of the upper inclined wall 31 toward the air outlet 17, and blows out obliquely downward from the air outlet 17 to the outside. Is done. In this way, the direction of the wind blown out from the blower outlet 17 is directed downward most.

  Further, when an input signal for setting the wind direction to the most upward direction is input from the wind direction input unit, the blower 5 drives the motor 93 of the rotation operation unit 91 to rotate the inner cylinder 58 as necessary. Thus, as shown in FIG. 11 (b), the entire internal outlet 97 is directed to the inclined wall 33 on the lower side of the projecting opening 25.

  In this case, the conditioned air introduced into the inner cylinder 58 from at least one of the rear duct 15B and the front duct 15F is caused by a difference in atmospheric pressure between the inside of the inner cylinder 58 and the outside of the air outlet 19. After being blown out from the internal air outlet 97 toward the lower inclined wall 33, it flows obliquely upward along the inner surface 33 a of the lower inclined wall 33, toward the air outlet 17, and obliquely upward from the air outlet 17 to the outside. Is blown out. In this way, the direction of the wind blown out from the blower outlet 17 is directed most upward.

  In addition, when an input signal for setting the wind direction to the center in the vertical direction is input from the wind direction input unit, the blower 5 drives the motor 93 of the rotation operation unit 91 as necessary to drive the inner cylinder 58. By rotating the, the internal air outlet 97 is brought into a state of being directed straight to the air outlet 17 of the air outlet 19 as shown in FIG.

  In this case, the conditioned air introduced into the inner cylinder 58 from at least one of the rear duct 15B and the front duct 15F is caused by a difference in atmospheric pressure between the inside of the inner cylinder 58 and the outside of the air outlet 19. The air is blown straight out from the internal air outlet 97 toward the air outlet 17 of the air outlet 19, and is blown out from the air outlet 17 to the outside in the front direction of the air outlet 17. In this way, the direction of the wind blown from the blower outlet 17 is directed to the center in the vertical direction.

  In addition, when an input signal for setting the wind direction slightly downward is input from the wind direction input unit, the blower 5 rotates the inner cylinder 58 by driving the motor 93 of the rotation operation unit 91 as necessary. Thus, as shown in FIG. 11 (d), the state where the internal air outlet 97 is directed over both the upper inclined wall 31 and the air outlet 17 in the projecting opening 25, that is, the upper edge of the air outlet 17. It is in a state where it is directed to the range including.

  In this case, the conditioned air introduced into the inner cylinder 58 from at least one of the rear duct 15B and the front duct 15F is caused by a difference in atmospheric pressure between the inside of the inner cylinder 58 and the outside of the air outlet 19. The air is blown out from the internal air outlet 97 toward both the upper inclined wall 31 and the air outlet 17. The conditioned air blown toward the upper inclined wall 31 flows obliquely downward along the inner surface 31a of the upper inclined wall 31 and heads toward the outlet 17, and the outlet 17 of the air outlet 19 from the internal outlet 97. The air flows into the air while colliding with the conditioned air that goes directly to the air and blows out from the air outlet 17 to the outside. At this time, the conditioned air blown from the air outlet 17 is pushed by the wind flowing obliquely downward along the inner surface 31a of the upper inclined wall 31 and is blown out from the air outlet 17 in a downward direction. Thus, the direction of the wind blown out from the blowout port 17 is slightly directed downward.

  Further, when an input signal for setting the wind direction slightly upward is input from the wind direction input means, the blower 5 drives the motor 93 of the rotation operation means 91 to rotate the inner cylinder 58 as necessary. Thus, as shown in FIG. 11 (e), the state where the internal air outlet 97 is directed over both the lower inclined wall 33 and the air outlet 17 in the air outlet 19, that is, the lower end of the air outlet 17. The state is directed to the range including the edge.

  In this case, the conditioned air introduced into the inner cylinder 58 from at least one of the rear duct 15B and the front duct 15F is caused by a difference in atmospheric pressure between the inside of the inner cylinder 58 and the outside of the air outlet 19. The air is blown out from the internal air outlet 97 toward both the lower inclined wall 33 and the air outlet 17 in the air outlet 19. The conditioned air blown toward the lower inclined wall 33 flows obliquely upward along the inner surface 33a of the lower inclined wall 33 and heads toward the blowout port 17, and the blowout of the air blower 19 from the internal blowout port 97. The air then merges while colliding with the conditioned air directly going to the outlet 17 and is blown out from the outlet 17. At this time, the conditioned air blown from the blower outlet 17 is pushed by the wind flowing obliquely upward along the inner surface 33a of the lower inclined wall 33 and blown upward and downward from the blower outlet 17. Thus, the direction of the wind blown out from the blowout port 17 is directed slightly upward.

  As described above, by operating the rotation operation of the inner cylinder 58 with the rotation operation means 91, the direction of the wind blown from the air outlet 17 of the air outlet 19 can be adjusted in the vertical direction. Also in the present embodiment, by combining the vertical wind direction control with the horizontal wind direction control, the direction of the wind blown from the outlet 17 can be adjusted to an intermediate direction between the vertical direction and the horizontal direction.

-Effect of Embodiment 2-
Also according to the second embodiment, the air blower 5 that can adjust the wind direction in multiple directions with a simple structure without having the fins for controlling the wind direction at the air outlet 17 can be realized. Can be reduced in size and weight and space saving.
