Japanese Utility Model Publication No. 4-52607

  However, in the grill device disclosed in Patent Document 1, in addition to having two sub-channels in addition to the main channel, a damper provided for each sub-channel separately from the mechanism for adjusting the air volume, and opening and closing these dampers Since a dial mechanism is required, the number of parts is large and the structure is complicated. In addition, the grill device of Patent Document 1 still has a plurality of horizontal fins that are visible from the outside, and has a simple structure with excellent design that does not have fins for controlling the wind direction at the air outlet. The air blower has not been realized.

  The present invention has been made in view of such points, and an object of the present invention is to control the wind direction with a simple structure without having a fin for controlling the wind direction at the air outlet. An object of the present invention is to provide an air blower capable of performing the above-mentioned.

  In order to achieve the above object, according to the present invention, a partition plate for radially partitioning the inside of the blowout cylinder having a blowout port is provided, and the partition plate is supported by a rotating shaft that is inserted through the inner center of the blowout cylinder. The direction of the wind blown out from the blowout port can be adjusted by rotating around the rotation axis.

  Specifically, the present invention is directed to an air blower capable of adjusting the direction of the wind blown from the air outlet, and takes the following solution.

  In other words, the first invention is formed in a cylindrical shape having at least one end opened, and has a blowout outlet in the peripheral wall portion for blowing the introduced air introduced into the inside from the open end, and at least the blowout opening on the inner peripheral surface. A blowout cylinder whose back side portion corresponding to the outer circumference is formed in a circumferential shape, and a blowout cylinder that is supported by a rotating shaft that is inserted through the inner center of the blowout cylinder at a position corresponding to the blowout opening in the blowout cylinder. A movable partition plate that is radially partitioned from the rotational axis to the circumferential inner circumferential surface of the blowout cylinder, and that is rotatable in a direction along the circumferential inner circumferential surface about the rotational axis; Is provided.

  In addition, "the inside of the blowing cylinder is radially partitioned from the rotation axis to the circumferential inner circumferential surface of the blowing cylinder" means that the inner circumferential surface of the blowing cylinder of the movable partition plate Meaning including not only the case where the outer end located on the side is in contact with the inner peripheral surface but also the case where the tip of the movable partition plate is slightly separated from the inner peripheral surface of the blowing cylinder and is close to the inner peripheral surface It is.

  Further, according to a first aspect of the present invention, there is provided a duct that is connected to an open end of the blowout cylinder, introduces air into the blowout cylinder from the open end, a blow source that blows air into the duct, and a movable partition plate. Rotation operation means for operating the rotation operation. In the first invention, the direction of the wind blown from the outlet is changed by rotating the movable partition plate by the rotation operation means and changing the partition position inside the blowout cylinder by the movable partition plate. It is characterized by changing in a direction orthogonal to the length direction.

  According to a second invention, in the blower device of the first invention, both ends of the blowout cylinder are opened, and the duct is connected to one open end of the blowout cylinder, and the other of the blowout cylinder The second duct is connected to the open end. Furthermore, 2nd invention is equipped with the air volume control means which controls separately the ventilation volume sent in the inside of a blowing cylinder from a 1st duct, and the ventilation volume sent into the inside of a blowing cylinder from a 2nd duct. . And the 2nd invention changes the direction of the wind which blows off from a blower outlet by changing the blast volume with respect to the inside of the blowing cylinder from at least one duct among the 1st duct and the 2nd duct by an air volume control means. It is characterized by changing in the direction of the length of the cylinder of the body.

  According to a third aspect of the present invention, in the blower of the first or second aspect, a fixed partition plate extending from the rotation shaft side toward the blowout port is provided between the rotation shaft and the blowout port. And 3rd invention is the straight line which connects the both ends edge of the direction orthogonal to the cylinder length direction of the blowing cylinder in a blower outlet, The front-end | tip which faces a blower outlet among both the edge of these blower outlets, and a fixed partition plate, The straight line connecting the two draws an equilateral triangle when viewed from the cylinder length direction of the blowing cylinder.

  According to the first aspect of the invention, the introduced air introduced from the duct into the blowout cylinder is a movable partition plate provided in the blowout cylinder, and is one-way in the direction along the inner peripheral surface of the blowout cylinder. Separated into an airflow flowing to the outlet along the inner peripheral surface of the cylindrical body and an airflow flowing to the outlet along the inner peripheral surface of the cylindrical body around the other in the direction along the inner peripheral surface of the outlet cylindrical body Is done. These two airflows flow in the opposite directions along the inner peripheral surface of the blowout cylinder to the blowout port, merge while colliding at and near the blowout port, and the combined introduced air blows out from the blowout port to the outside. Is done. The two air currents separated by the movable partition plate are larger when the distance of the portion along the inner peripheral surface of the blowout cylinder along which the air stream travels from the movable partition plate to the blowout port is longer when the airflow blows out from the airflow blowout port. In addition to the increased directivity, the space in which the airflow flows increases, and the airflow by the airflow increases accordingly. From this, by changing the partitioning position of the movable partition plate by the rotation operation means, the balance of the blowing intensity by these two airflows changes, and the direction of the wind blown from the blowout port is orthogonal to the tube length direction of the blowout cylinder It can be changed according to the direction. Therefore, it is possible to control the wind direction with a simple structure without having a fin for controlling the wind direction at the air outlet. As a result, it is possible to realize a simple air blower with an appearance of only the opening at the air outlet, and to improve the design of the air blower and thus a structure incorporating the air blower.

  According to the second invention, the introduced air introduced into the inside of the blowing cylinder from the first duct and the second duct is directed to the outlet side from both open ends of the blowing cylinder, and corresponds to the outlet. They merge while colliding with each other and are blown out from the outlet. Therefore, the direction of the wind blown from the outlet is changed in the cylinder length direction of the blowout cylinder by changing the flow rate of air to the inside of the blowout cylinder from at least one of the first duct and the second duct by the air volume control means. But it can be changed and the direction of the wind can be controlled in multiple directions.

  According to the third aspect of the present invention, the interior of the blowout cylinder is between the rotating shaft and the blowout port, that is, in front of the blowout port, while the space through which the two air streams separated by the movable partition plate flow is partitioned by the fixed partition plate. Since this fixed partition plate is too long and does not interfere with the wind blown out from the blowout port and causing a decrease in the blown amount, it prevents the occurrence of turbulent flow in front of the blowout port inside the blowout cylinder. It is possible to achieve both the securing of the amount of air blown from the air outlet.

FIG. 4 is a longitudinal sectional view of the cylindrical blowing structure 13 corresponding to the line IV-IV in FIG. The cylindrical blowing structure 13 is installed at a position above a glove box (not shown) on the front side of the passenger seat in a state where the cylinder length direction is in a posture parallel to the vehicle width direction.

  As shown in FIGS. 2 to 4, the tubular blowing structure 13 includes a blowing cylinder 21 having a blowing outlet 25 that blows conditioned air to the outside (vehicle interior), and a blowing outlet 25 of the blowing cylinder 21. And a wind direction adjusting mechanism 23 that adjusts the direction of the blowing wind, and the wind direction adjusting mechanism 23 is housed inside the blowing cylinder 21. The blowout cylinder 21 is a resin molded product, and is molded by blow molding or injection molding.

  The blow-out cylinder 21 is formed in a cylindrical shape whose both ends are open, and has a circumferential inner peripheral surface 22 throughout. As shown in FIG. 3, among the blowout cylinders 21, a left duct 17L is fitted into and connected to the left open end, and a right duct 17R is connected to the right open end. It is inserted into the body 21 and connected. The left duct 17L and the right duct 17R are adapted to introduce conditioned air into the blowout cylinder 21 from the open ends connected to each other. Moreover, the blower outlet 25 extended in the cylinder length direction at the center part in the cylinder length direction of the vehicle rear side among the surrounding wall parts of the blowing cylinder 21 is formed in the rectangular shape by the front view.

  This blower outlet 25 penetrates the peripheral wall part of the blowing cylinder 21, and is an opening through which the conditioned air introduced into the cylinder 21 from the left duct 17L and the right duct 17R through the open end of the blow cylinder 21 is blown out. It is. Further, in the peripheral part of one open end (the right open end in the example shown in FIG. 2) of the blowing cylinder 21, the upper part and the front part extend in a concave shape in the left-right direction, and the inside of the blowing cylinder 21 and Positioning grooves 27 opened to the right are formed at intervals of about 90 degrees.

  The wind direction adjusting mechanism 23 includes a rotating shaft 31 inserted through the inner center of the blowing cylinder 21, a pair of bearing portions 35 that rotatably supports the rotating shaft 31 on both the left and right sides of the blowing cylinder 21, and the pair The movable partition plate 33 supported by the rotating shaft 31 between the bearing portions 35 and the fixed partition plate 43 disposed behind the rotating shaft 31 (on the outlet 25 side) between the pair of bearing portions 35. ing.

  Each bearing portion 35 includes a cylindrical holding portion 37 through which the rotation shaft 31 is inserted, an annular outer ring portion 38 disposed with its outer peripheral surface in contact with the inner peripheral surface 22 of the blowout cylinder 21, and these A plurality of (four in the example shown in FIG. 2) connecting portions 39 for connecting the holding portion 37 and the outer ring portion 38 are provided, and the holding portion 37, the outer ring portion 38 and the connecting portion 39 are integrally formed as a whole. It is shaped like a wheel.

  Each connecting portion 39 is formed in a thin small plate shape extending straight from the holding portion 37 in the radial direction of the outer ring portion 38. The plurality of connecting portions 39 are arranged so as to extend radially, for example, vertically and horizontally on the holding portion 37 at intervals. The bearing portion 35 can send conditioned air to the inner central side of the blowing cylinder 21 through the connecting portions 39 adjacent to each other in this way.

  In addition, a closing plate 41 that partially closes between the adjacent connecting portions 39 is provided at the rear portion of each bearing portion 35. The closing plate 41 is located on the outer side of the connecting portion 39 located on the rear side, that is, on the left side of the bearing portion 35, on the left side of the connecting portion 39, and on the right side of the connecting portion 35, on the right side of the connecting portion 39. Are integrally formed. As a result, the conditioned air introduced from the duct 17 into the blowout cylinder 21 passes through the bearing portion 35, and then from the rear side portion closed by the closing plate 41, the inner central side of the blowout cylinder 21. However, it flows from the closing plate 41 to the inner central side of the cylindrical body 21 through the rear side (vehicle front side) of the blowing cylindrical body 21.

  The rotating shaft 31 is inserted through the holding portions 37 of the pair of bearing portions 35 and protrudes from the bearing portions 35 to the left and right sides. The left end portion of the rotating shaft 31 protruding leftward from the left bearing portion 35 is secured to the bearing portion 35 by fastening with a speed nut 51. Further, the right end portion of the rotating shaft 31 protruding rightward from the right bearing portion 35 is inserted into the insertion hole 18 formed in the right duct 17R and protrudes outside the right duct 17R.

  The right end portion of the rotating shaft 31 is secured to the right duct 17R by being fastened by a driven gear 53 that constitutes the rotation operation means 14 described later outside the right duct 17R. The outer peripheral surface of the right end portion 31 a of the rotating shaft 31 is knurled. The processed portion 31 a is press-fitted into the bearing hole 54 of the driven gear 53, so that the driven gear 53 is moved to the right end of the rotating shaft 31. It is fixed to the part.

  The movable partition plate 33 is formed in a rectangular strip shape extending along the rotation shaft 31, and the rotation shaft 31 passes through the inside of the blowing cylinder 21 at a position corresponding to the outlet 25 in the blowing cylinder 21. To the inner peripheral surface 22 of the blowing cylinder 21 in the radial direction. The outer end of the movable partition plate 33 located on the inner peripheral surface 22 side of the blowout cylinder 21 is in contact with the inner peripheral surface 22 or is slightly separated from the inner peripheral surface 22 of the blowout cylinder 21. The state is close to the surface 22.

  A pair of attachment pieces 34 for attaching the movable partition plate 33 to the rotating shaft 31 are provided on both the left and right sides of the movable partition plate 33. Each of the attachment pieces 34 has an insertion hole 32 that is inserted into the rotation shaft 31, and is fixed to the rotation shaft 31 by press-fitting the rotation shaft 31 into the insertion hole 32. Thus, the movable partition plate 33 can be rotated in the direction along the inner peripheral surface 22 of the blowing cylinder 21 around the rotation shaft 31 and rotated integrally with the rotation shaft 31 in accordance with the rotation operation of the rotation shaft 31. Thus, it is possible to change the partition position inside the blowing cylinder 21. Thereby, the air blower 7 can change the direction of the wind which blows off from the blower outlet 25 by the up-down direction orthogonal to the cylinder length direction of the blowing cylinder 21.

  That is, the introduced air introduced from the duct 17 into the blowout cylinder 21 is when the partition position of the movable partition plate 33 is a predetermined position, for example, the position where the outer end of the partition plate 33 faces the front side. The movable partition plate 33 flows clockwise along the inner peripheral surface 22 of the blowout cylinder 21 as viewed from the right side of the cylindrical body 21, and a portion from the lower side to the rear side of the inner peripheral surface 22 is moved. And the lower airflow flowing obliquely upward to the outlet 25 and the inner peripheral surface 22 of the blowout cylinder 21, flowing counterclockwise as viewed from the right side of the cylindrical body 21, Of these, it is separated into an upward airflow that flows to the outlet 25 obliquely downward through a portion from the upper side to the rear side. These two airflows flow in the opposite directions along the inner peripheral surface 22 of the blowout cylinder 21 to the blowout port 25 and merge while colliding with each other at the blowout port 25 and the vicinity thereof. 25 is blown out. The two air currents separated by the movable partition plate 33 are such that the longer the distance of the portion of the inner peripheral surface 22 of the blowout cylinder 21 along which the air flow is from the movable partition plate 33 to the outlet 25, The directivity at the time of blowing from the outlet 25 is increased, and the space through which the airflow flows is expanded, and the air volume by the airflow is increased accordingly. From this, by changing the partition position of the movable partition plate 33, the balance of the blowing strength by these two airflows changes, and the direction of the wind blown from the blowout port 25 is orthogonal to the tube length direction of the blowout cylinder 21. The direction can be changed in the vertical direction.

  The rotation operation means 14 includes a driven gear 53 fixed to the right end portion of the rotary shaft 31 described above, and a motor 57 in which a drive gear 55 that meshes with the driven gear 53 is provided on the output shaft 58. The motor 57 is a motor that can switch the rotation direction between forward rotation and reverse rotation. The movable partition plate 33 rotates together with the rotating shaft 31 by driving the motor 57 and transmitting the rotational power of the driving gear 55 to the rotating shaft 31 via the driven gear 53. The rotation operation means 14 executes driving of the motor 57 and switching of the rotation direction based on an input signal for setting the wind direction from a wind direction input means such as a panel for occupant operation provided on the instrument panel 1 or a dial. The rotating operation of the movable partition plate 33 is operated.

  The fixed partition plate 43 is formed in a strip shape extending along the rotation shaft 31 and is disposed between the rotation shaft 31 and the outlet 25 in a state of being spaced apart from the rotation shaft 31 with a slight gap. Thus, a space in which two airflows (upper airflow and lower airflow) separated by the movable partition plate 33 flow in front of the air outlet 25 is partitioned. Both ends of the fixed partition plate 43 are integrally connected to a connecting portion 39 located on the rear side of the holding portion 37 in the corresponding bearing portion 35. In other words, the connecting portions 39 located on the rear side of the holding portion 37 in the pair of bearing portions 35 are connected via the fixed partition plate 43. The fixed partition plate 43 extends from the rotary shaft 31 toward the blower outlet 25 until the front end (rear end) facing the blower outlet 25 is aligned with the closing plate 41 in the left-right direction.

  The positional relationship between the front end of the fixed partition plate 43 facing the air outlet 25 and the air outlet 25 is such that the distance between the vertical edges of the air outlet 25 (the opening width in the vertical direction) a and the air outlet 25 The distances b and c between the upper and lower end edges and the rear end of the fixed partition plate 43 are equal. That is, the straight line connecting the upper and lower end edges of the outlet 25 and the straight line connecting the upper and lower end edges of the outlet 25 and the rear end of the fixed partition plate 43 are viewed from the cylinder length direction of the outlet cylinder 21. Draw an equilateral triangle.

  As a result, it is possible to prevent the wind direction control due to the rotation operation of the movable partition plate 33 described above from becoming unstable due to the fixed partition plate 43 being too far from the outlet 25. In addition, the fixed partition plate 43 is too long so that it does not impede the wind blown from the blowout port 25 and blown out from the blowout port 25 to cause a decrease in the blown amount. Thereby, it is possible to achieve both prevention of turbulent flow in front of the air outlet 25 inside the air outlet cylinder 21 and securing of the amount of air blown from the air outlet 25.

  Further, on the outer peripheral surface of the outer ring portion 38 of the one bearing portion 35 (the right-side bearing portion 35 in the example shown in FIG. 2) of the pair of bearing portions 35, the front portion and the upper portion are positioned so as to extend in the lateral direction. The protruding pieces 40 are provided with an interval of about 90 degrees. The wind direction adjusting mechanism 23 slides and inserts these positioning protrusions 40 into the positioning grooves 27 of the blowing cylinder 21 from the right side so that the fixed partition plate 43 has a predetermined posture in which the rear end faces the outlet 25. Is positioned.

  As shown in FIG. 1, the air volume control unit 15 is connected to each open end of the left duct 17L and the right duct 17R on the side opposite to the connection side with the blowing cylinder 21. The air volume control unit 15 includes a damper (not shown) that adjusts the air flow rate to the ducts 17L and 17R for each of the left duct 17L and the right duct 17R. Then, the air volume control unit 15 blows air to the left duct 17L and the right duct 17R blown by the blower 9 based on the input signal for setting the wind direction from the wind direction input means, and thus the blowout cylinder 21 from the left duct 17L. The amount of air blown into the interior of the pipe and the amount of air blown into the blowout cylinder 21 from the right duct 17R are individually controlled.

  In the air blower 7 having the above-described configuration, the movable partition plate 33 is rotated by the rotation operation means 14, and the partition position of the movable partition plate 33 inside the blowout cylinder 21 by the movable partition plate 33 is changed, whereby the air outlet 25. The direction of the wind blown out from the top is changed in the vertical direction, and the air volume control unit 15 changes the air flow rate from the at least one duct 17 out of the left duct 17L and the right duct 17R to the inside of the blow cylinder 21 by The direction of the wind blown from the outlet 25 can be changed in the cylinder length direction of the blowing cylinder 21, that is, in the left-right direction.

  Below, the wind direction control of the air blower 7 is demonstrated, referring FIG.5 and FIG.6. 5A to 5E are longitudinal sectional views of the cylindrical blowing structure 13 corresponding to FIG. 4 showing an example of the valuation for controlling the wind direction in the vertical direction in the blower 7. 6A to 6E are cross-sectional views of the cylindrical blowing structure 13 showing an example of a valuation for controlling the wind direction in the left-right direction in the blower 7.

  In addition, the arrow shown as a continuous line in these Fig.5 (a)-(e) and Fig.6 (a)-(e) has shown the flow of the conditioned air in the inside of the blowing cylinder 21. FIG. Moreover, the arrow shown with a dashed-dotted line in FIG. 6 (a), (b) has shown the compressed air which stayed in the inside of the blowing cylinder 21. FIG. In FIGS. 6A to 6E, only the blowout cylinder 21 is shown, and other configurations such as the movable partition plate 33 and the fixed partition plate 43 are omitted.

  First, an operation for controlling the direction of the wind blown from the blower outlet 25 of the blower 7 in the vertical direction will be described with reference to FIGS.

  When an input signal for setting the wind direction to the most upward direction is input from the wind direction input unit, the blower device 7 rotates the movable partition plate 33 by driving the motor 57 of the rotation operation unit 14 as necessary. As shown in FIG. 5A, the outer end of the movable partition plate 33 is set to a state corresponding to the upper end edge of the air outlet 25.

  In this case, the conditioned air introduced into the blowout cylinder 21 from at least one of the left duct 17L and the right duct 17R is caused by the pressure difference between the inside and the outside of the blowout cylinder 21. The blower cylinder 21 flows clockwise along the inner peripheral surface 22 as viewed from the right side, and passes obliquely upward to the blowout port 25 via a portion from the lower side to the rear side of the inner peripheral surface 22. The air is blown obliquely upward from the air outlet 25 to the outside (vehicle interior). In this way, the direction of the wind blown out from the blower outlet 25 is directed most upward.

  Moreover, when the input signal which sets a wind direction to the most downward direction is input from the wind direction input means, the air blower 7 drives the motor 57 of the rotation operation means 14 and rotates the movable partition plate 33 as necessary. Thus, as shown in FIG. 5B, the outer end of the movable partition plate 33 is set to a state corresponding to the lower end edge of the air outlet 25.

  In this case, the conditioned air introduced into the blowout cylinder 21 from at least one of the left duct 17L and the right duct 17R is caused by the pressure difference between the inside and the outside of the blowout cylinder 21. The blower cylinder 21 flows in a counterclockwise direction when viewed from the right side along the inner peripheral surface 22 of the inner peripheral surface 22, and passes obliquely downward to the outlet 25 through a portion from the upper side to the rear side of the inner peripheral surface 22. The air is blown obliquely downward from the air outlet 25 to the outside. In this way, the direction of the wind blown out from the blower outlet 25 is directed most downward.

  Further, 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 device 7 drives the motor 57 of the rotation operation unit 14 as necessary to move the movable partition plate 33. Is rotated so that the outer end of the movable partition plate 33 is directed in the opposite direction to the air outlet 25 as shown in FIG.

  In this case, the conditioned air introduced into the blowout cylinder 21 from at least one of the left duct 17L and the right duct 17R is the movable partition plate 33 along the inner peripheral surface 22 of the blowout cylinder 21. A downward airflow that flows clockwise as viewed from the right side of the blowout cylinder 21 and flows obliquely upward to the blowout outlet 25 via a portion from the lower side to the rear side of the inner peripheral surface 22, and the blowout cylinder 21. Flows in the counterclockwise direction when viewed from the right side of the blow-out cylinder 21 along the inner peripheral surface 22 of the inner peripheral surface 22, and flows to the outlet 25 obliquely downward through a portion from the upper side to the rear side of the inner peripheral surface 22. It is separated into the upper airflow.

  These two airflows flow in the opposite directions along the inner peripheral surface of the blowout cylinder 21 to the blowout port 25 and merge while colliding with each other at the blowout port 25 and the vicinity thereof. From outside. At this time, the blowing strength of the conditioned air by the upper airflow and the lower airflow separated by the movable partition plate 33 is such that the partitioning position of the movable partition plate 33 inside the blowout cylinder 21 is half the upper and lower half inside the cylinder 21. Therefore, the conditioned air introduced from the duct 17 into the blowout cylinder 21 is blown out from the blowout outlet 25 toward the center in the vertical direction. In this way, the direction of the wind blown from the blower outlet 25 is directed to the center in the vertical direction.

  Further, when an input signal for setting the wind direction slightly upward is input from the wind direction input unit, the blower device 7 drives the motor 57 of the rotation operation unit 14 to rotate the movable partition plate 33 as necessary. As a result, as shown in FIG. 5D, the outer end of the movable partition plate 33 is set to be in a state of being directed obliquely forward on the upper side.

  In this case, the conditioned air introduced into the blowout cylinder 21 from at least one of the left duct 17L and the right duct 17R is separated into an upper airflow and a lower airflow by the movable partition plate 33, and these two The air currents merge while colliding at and near the air outlet 25, and are blown out from the air outlet 25. At this time, the partition position of the movable partition plate 33 inside the blowout cylinder 21 is such that the space in which the upper airflow flows is relatively narrow and the space in which the lower airflow flows is relatively wide in the cylinder 21. Since the conditioned air blowing strength caused by the lower airflow separated by the movable partition plate 33 is stronger than the conditioned air blowing strength caused by the upper airflow, the air flows from the duct 17 to the inside of the blowout cylinder 21. The introduced conditioned air is pushed by the wind flowing obliquely upward toward the air outlet 25 by the lower airflow, and is blown upward and downward from the air outlet 25. In this way, the direction of the wind blown out from the blower outlet 25 is directed slightly upward.

  Further, when an input signal for setting the wind direction slightly downward is input from the wind direction input unit, the blower device 7 drives the motor 57 of the rotation operation unit 14 to rotate the movable partition plate 33 as necessary. Thus, as shown in FIG. 5 (e), the outer end of the movable partition plate 33 is set to be in a state of being directed obliquely downward on the lower side.

  In this case, the conditioned air introduced into the blowout cylinder 21 from at least one of the left duct 17L and the right duct 17R is separated into an upper airflow and a lower airflow by the movable partition plate 33, and these two The air currents merge while colliding at and near the air outlet 25, and are blown out from the air outlet 25. At this time, the partition position of the movable partition plate 33 inside the blowout cylinder 21 is such that the space in which the upper airflow flows is relatively wide and the space in which the lower airflow flows is relatively narrow in the cylinder 21. Therefore, the conditioned air blowing strength by the upper airflow separated by the movable partition plate 33 is stronger than the conditioned air blowing strength by the lower airflow, so that the duct 17 enters the inside of the blowing cylinder 21. The introduced conditioned air is pushed by the wind that flows obliquely downward toward the air outlet 25 due to the upward air flow, and is blown downward from the air outlet 25 to the outside. In this way, the direction of the wind blown out from the blower outlet 25 is directed slightly downward.

  Next, an operation for controlling the direction of the wind blown from the blower outlet 25 of the blower 7 in the left-right direction will be described with reference to FIGS.

  When the input signal for setting the wind direction to the leftmost is input from the wind direction input means, the air blower 7 eliminates the air flow to the left duct 17L by the air volume control unit 15, that is, stops the air flow to the left duct 17L. At the same time, the conditioned air from the air conditioner 5 is blown only to the right side duct 17R, with the blast amount for the right side duct 17R being set to a predetermined level according to the wind intensity level set for the occupant.

  In this case, the conditioned air introduced from the right duct 17R into the blowout cylinder 21 flows from the right to the left inside the blowout cylinder 21, as shown in FIG. Due to the pressure difference between the inside and the outside of 21, the flow is changed to an oblique left flow directed toward the air outlet 25 toward the air outlet 25, and blown obliquely leftward from the air outlet 25. In this way, the direction of the wind blown out from the blower outlet 25 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 device 7 eliminates the amount of air blown to the right duct 17R by the air volume control unit 15, that is, blows air to the right duct 17R. In addition, the conditioned air from the air conditioner 5 is blown only to the left duct 17L, with the blast volume for the left duct 17L 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 left duct 17L into the blowing cylinder 21 flows from the left to the right inside the blowing cylinder 21, as shown in FIG. Due to the pressure difference between the inside and the outside of 21, the flow is changed to a diagonally rightward flow toward the blowout port 25 and is blown obliquely rightward from the blowout port 25. In this way, the direction of the wind blown out from the blower outlet 25 is directed most rightward.

  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 blower device 7 is supplied by the air volume control unit 15 to the blowing strength to the left duct 17L and to the right duct 17R. The air flow rate for the left duct 17L and the right duct 17R is set so that the air blowing intensity is the same level.

  In this case, the conditioned air introduced into the inside of the blowing cylinder 21 from the left duct 17L and the right duct 17R, respectively, due to the pressure difference between the inside and outside of the blowing cylinder 21, as shown in FIG. It is guided to the outlet 25 side and blown out from the outlet 25. In the process, the conditioned air introduced from the left duct 17L into the blowout cylinder 21 and the conditioned air introduced from the right duct 17R into the blowout cylinder 21 collide at the outlet 25 and the vicinity thereof. Join together. At this time, the conditioned air introduced from the left duct 17L and the conditioned air introduced from the right duct 17R have the same level of air blowing strength, and thus are blown out from the outlet 25 toward the center in the left-right direction. . In this way, the direction of the wind blown from the blower outlet 25 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 of the blower 7, the air flow control unit 15 determines that the blowing intensity to the right duct 17 </ b> R is applied to the left duct 17 </ b> L. The air volume for the left duct 17L and the right duct 17R is set so as to be stronger than the air intensity.

  In this case, the conditioned air introduced into the inside of the blowing cylinder 21 from the left duct 17L and the right duct 17R, as shown in FIG. 6 (d), due to the pressure difference between the inside of the blowing cylinder 21 and the outside, The air is guided to the air outlet 25 side, merges while colliding with the air outlet 25 and the vicinity thereof, and is blown out from the air outlet 25. At this time, since the blowing strength of the conditioned air introduced from the right duct 17R is stronger than the blowing strength of the conditioned air introduced from the left duct 17L, the left duct 17L and the right duct 17R enter the inside of the blowing cylinder 21. The introduced conditioned air is pushed by the wind flowing obliquely leftward toward the blowout port 25 introduced from the right duct 17R, and is blown out from the blowout port 25 to the outside in a left-and-right direction. In this way, the direction of the wind blown out from the blower outlet 25 is directed slightly to the left.

  Further, 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 of the blower 7, the air flow control unit 15 determines the intensity of the air blow to the left duct 17 </ b> L to the right duct 17 </ b> R. The air volume for the left duct 17L and the right duct 17R is set so as to be stronger than the air intensity.

  In this case, the conditioned air introduced into the inside of the blowing cylinder 21 from the left duct 17L and the right duct 17R is caused by the pressure difference between the inside and outside of the blowing cylinder 21, as shown in FIG. The air is guided to the air outlet 25 side, merges while colliding with the air outlet 25 and the vicinity thereof, and is blown out from the air outlet 25. At this time, since the blast strength of the conditioned air introduced from the left duct 17L is stronger than the blast strength of the conditioned air introduced from the right duct 17R, the conditioned air is introduced from the left duct 17L and the right duct 17R into the blowing cylinder. The conditioned air is pushed by the wind flowing obliquely rightward toward the air outlet 25 introduced from the left duct 17L, and is blown out from the air outlet 25 to the outside in a right direction. In this way, the direction of the wind blown out from the blower outlet 25 is directed slightly to the right.

  As described above, the air blower 7 adjusts the direction of the wind blown from the air outlet 25 by operating the rotation operation of the movable partition plate 33 by the rotation operation means 14, and the left air duct 17 </ b> L is adjusted by the air flow control unit 15. And the direction of the wind which blows off from the blower outlet 25 can be adjusted to the left-right direction by controlling individually the ventilation volume with respect to the right side duct 17R. Further, according to the combination of the vertical and horizontal wind direction control, the direction of the wind blown from the outlet 25 is in the middle direction between the vertical direction and the horizontal direction, that is, the upper left direction, the upper right direction, the lower left direction, and the lower right direction. Can also be adjusted.

-Effect of the embodiment-
According to this embodiment, the blower outlet 25 that blows out conditioned air does not have a fan for controlling the wind direction, and the direction of the wind blown out from the blower outlet 25 can be adjusted vertically and horizontally with a simple structure. Thereby, the air blower 7 and the air-conditioning unit 3 provided with the air blower 25 which are simple in appearance can be realized, and the design of the instrument panel 1 incorporating the air-conditioning unit 3 can be improved.

  Moreover, since the cylindrical blowout structure 13 and the air duct 11 constituting the blower device 7 of this embodiment do not require a large installation space in the vehicle front-rear direction, the degree of freedom of the installation location is increased, and it has been difficult to install conventionally. It can also be installed on the back side of the instrument panel 1 in front of the passenger seat.

  In addition, in the said embodiment, although the blowing cylinder 21 was cylindrical and had the circumferential inner peripheral surface 22 over the whole, it is not restricted to this, The blowing cylinder 21 is cylindrical. The inner peripheral surface 22 has a cylindrical shape in which at least the back side portion (the vehicle front side portion) corresponding to the air outlet 25 is formed in a circular shape, and the movable partition plate 33 rotates. May be allowed in a state where the outer end of the partition plate 33 is aligned.

  Moreover, in the said embodiment, although the structure which rotates the movable partition plate 33 using the motive power of the motor 57 was mentioned as an example, it was not restricted to this, and it replaced with the motor 57 for rotating the rotating shaft 31. An operation lever may be provided as the rotation operation means 14, and the movable partition plate 33 may be manually rotated using the operation lever.

  Moreover, in the said embodiment, the both ends of the blowing cylinder 21 are open | released, conditioned air is introduce | transduced into the inside of the cylinder 21 from each duct 17L, 17R connected to both the open ends of the blowing cylinder 21, and at least one side Although the description has been given of the configuration in which the direction of the wind blown from the blower outlet 25 can be changed in the left-right direction by changing the amount of air blown from the duct 17 to the inside of the blowout cylinder 21 by the airflow control unit 15. Instead, the blowout cylinder 21 may have only one end opened and the other end closed, and conditioned air enters the cylinder 21 from the duct 17 connected to one open end of the blowout cylinder 21. The direction of the wind blown out from the blower outlet 25 may be changed only in the vertical direction by rotating the movable partition plate 33.

  Moreover, in the said embodiment, although the air volume control part 15 was provided with the damper which adjusts the ventilation volume with respect to the left duct 17L and the right duct 17R, what can control the ventilation volume with respect to the left duct 17L and the right duct 17R separately. If so, the amount of air blown to the left duct 17L and the right duct 17R may be adjusted by something other than the damper.

  Moreover, in the said embodiment, although the cylindrical blowing structure 13 was installed in the upper position of the glove box in front of a passenger seat, it is not restricted to this, The cylindrical blowing structure 13 which comprises the air blower 7 Since it does not require a large installation space as described above, it can be installed at other locations such as a door trim.

  As described above, the present invention is useful for a blower capable of adjusting the wind direction, and in particular, the air direction is controlled with a simple structure without having a fin for controlling the wind direction at the air outlet. It is suitable for the blower that is required.
