Description

  The present invention includes a housing (retainer) that defines an air inlet and an air outlet, an intake valve (damper) that can adjust the flow direction and amount of air from the air inlet to the air outlet, and an air flow that passes through the air outlet. The present invention relates to an air blowing device including a wind direction adjusting plate (fin) capable of adjusting a flow direction.

  2. Description of the Related Art Conventionally, an air blowing device that supplies air for air conditioning to the interior of an automobile has been proposed. This type of air blowing device is generally provided with a wind direction adjusting plate for adjusting the flow direction and the like of an air flow blown out from the device (hereinafter referred to as “blowing air flow”).

  For example, one of the conventional air blowing devices (hereinafter referred to as “conventional device”) includes a cylindrical casing and a plurality of wind direction adjusting plates provided at an opening end (air outlet) in front of the casing. It is equipped with. Specifically, the conventional apparatus includes a first adjustment plate (lateral fin) that can be rotated around an axis perpendicular to the axis of the housing, and a plurality of wind direction adjustment plates that are perpendicular to the first adjustment plate. A second adjustment plate (vertical fin) that can rotate around the axis is provided. That is, the first adjustment plate and the second adjustment plate are arranged so that their rotational axes are in a vertical positional relationship. As a result of this configuration, the conventional apparatus can change the flow direction of the blown air flow up, down, left and right as the first adjustment plate and the second adjustment plate rotate (for example, see Patent Document 1). reference.).

  An air blowing device having a cylindrical casing as in the conventional apparatus normally takes in air for cooling and heating from an open end (intake port) at the rear of the casing. Therefore, hereinafter, for convenience, such an air blowing device is referred to as a “rear-intake type air blowing device”.

JP 2009-160981 A

  When a rear intake type air blowing device is attached to an automobile or the like, generally, a tubular intake duct is connected to the rear (intake port) of the air blowing device. At this time, from the viewpoint of taking in the required amount of air as efficiently as possible (for example, while minimizing the pressure loss as much as possible), in general, the intake air is arranged so that the axis of the air blowing device coincides with the axis of the intake duct. A duct is connected to the air blowing device. In other words, the back-intake type air blowing device is generally designed on the assumption that the flow direction of the air flow does not change at the connection portion between the intake duct and the air blowing device.

  For this reason, the rear-intake type air blowing device is generally attached to a place (for example, the periphery of an instrument panel of an automobile) where there is room in the rear space to the extent that the above-described intake duct can be installed. On the other hand, if the rear air intake type air blowing device is installed in a place where there is not enough room in the back space (for example, the ceiling and pillar portion of an automobile), the above-described intake duct cannot be installed and the device is efficiently installed. Due to the inability to take in air or the like, the air blowing device may not exhibit the performance as designed. Therefore, the back-intake type air blowing device is generally not suitable for installation in a place where there is not enough room in the back space.

  An object of the present invention is to provide an air blowing device that can be installed without impairing the performance as an air blowing device even in a place where there is not enough room in the back space.

  In order to achieve the above object, an air blowing device of the present invention includes a “housing” that defines an air inlet and an air outlet, and an adjustable flow direction and amount of air from the air inlet to the air outlet. An "intake valve" and a "wind direction adjusting plate" capable of adjusting the flow direction of air passing through the outlet.

Specifically, the housing is
It has a cylindrical shape with one end being an open end and the other end being closed, and opens to the other side so as to face the first intake port and the “first intake port” that opens to one side surface as the intake port It has a “second air inlet” and is configured to have the opening end as the outlet.

Furthermore, the wind direction adjusting plate is
It is provided in the vicinity of the outlet so as to be rotatable around a rotation axis perpendicular to the axis of the housing.

In addition, the intake valve
Including "first valve" and "second valve" which can rotate in conjunction with each other, more specifically,
The first valve has a plate shape covering the first air inlet;
The second valve has a plate shape covering the second air inlet;
The rotation axis of the first valve is perpendicular to both the rotation axis of the wind direction adjusting plate and the axis of the housing, and passes through the end of the first valve on the other end side,
The rotation axis of the second valve is perpendicular to both the rotation axis of the airflow direction adjusting plate and the axis of the housing, and passes through the end of the second valve on the other end side.
It is configured as follows.

  According to the above configuration, air for air conditioning and the like is taken into the inside of the housing through the “first air inlet” and the “second air inlet” that are opened “to face each other” on the “side surface” of the housing. Then, the air is blown out from the “air outlet” which is the open end of the housing. At this time, the flow direction or the like of the blown air flow is adjusted by an “intake valve” that opens and closes each intake port and a “wind direction adjusting plate” that is provided in the vicinity of the discharge port.

  Specifically, the “first valve” having “a plate shape covering the first intake port” rotates around the rotation axis “passes through the end portion on the other end side”, thereby the first intake port. Is opened and closed. Furthermore, the “flow direction and amount of air from the intake port toward the outlet” is adjusted in accordance with the rotation angle of the first valve. Similarly, the “second valve” “having a plate shape covering the second intake port” rotates around the rotation axis “passes the end on the other end”, thereby opening and closing the second intake port. Is done. Further, the “flow direction and amount of air from the intake port to the outlet” is adjusted in accordance with the rotation angle of the second valve.

  Further, the rotation axis of the wind direction adjusting plate is “perpendicular to the axis of the housing”, and the rotation axis of each intake valve (first valve and second valve) is “the rotation axis of the wind direction adjusting plate and the Since it is “perpendicular to both axes of the housing”, the wind direction adjusting plate and each intake valve (first valve and second valve) are arranged so that their rotational axes are in a vertical positional relationship. Yes.

  Therefore, if the rotation angles of the first valve and the second valve are operated while being “linked to each other”, in addition to the “amount” of the blown air flow, a direction corresponding to the rotation direction of the intake valves (for example, air blowing The “flow direction” of the blown air flow can be adjusted in the left-right direction of the device. Further, by operating the rotation angle of the wind direction adjusting plate, the “flow direction” of the blown air flow can be adjusted in a direction perpendicular to the rotation direction of each intake valve (for example, the vertical direction of the air blowing device). In addition, since the air inlet is present on the “side surface” of the housing, air can be efficiently taken into the housing regardless of the size of the back space of the air blowing device (see, for example, FIG. 1).

  Therefore, the air blowing device of the present invention can be installed without impairing the performance as an air blowing device even in a place where there is no room in the back space, as compared with a back-intake type air blowing device like the conventional device. Is possible.

  The configuration and effects of the air blowing device of the present invention have been described above. Next, several embodiments (embodiments 1 and 2) of the air blowing device of the present invention will be described below.

・ Mode 1
In the air blowing device of the present invention, the first valve and the second valve need only be “rotatable in conjunction with each other” so that the flow direction and amount of the blown air flow can be adjusted. The embodiment is not particularly limited.

For example, the first valve and the second valve are:
“First state” in which both the first air inlet and the second air inlet are closed;
“Second state” in which only the first intake port is opened,
A “third state” in which both the first air inlet and the second air inlet are opened, and
“Fourth state” in which only the second intake port is opened,
In this order, the intake ports can be rotated in conjunction with each other so as to open and close (see, for example, FIGS. 3 to 6).

  According to the above configuration, when the intake valve is in the “first state”, air is not taken into the housing, and the amount of the blown air flow becomes zero.

  Next, when the intake valve is in the “second state”, since the air is taken into the housing through only the first intake port, the flow direction of the blown air flow corresponds to the rotation angle of the first valve. (For example, the blown air flow flows in an oblique direction away from the first air inlet).

  Further, when the intake valve is in the “third state”, air is taken into the housing through both the first intake port and the second intake port, and the air collides inside or outside the housing. -Because of the merge, the flow direction of the blown air flow changes corresponding to the rotation angle of the first valve and the second valve (for example, the blown air flow in the front direction around the axis of the air blowing device) Flows.)

  In addition, when the intake valve is in the “fourth state”, air is taken into the housing through only the second intake port, so that the flow direction of the blown air flow becomes the rotation angle of the second valve. Will change accordingly. Since the second intake port is opened to face the first intake port, the flow direction of the blown air flow in the fourth state is opposite to the flow direction of the blown air flow in the second state (for example, The blown air flow flows in an oblique direction away from the second intake port).

  Therefore, when the intake valve rotates while changing its state in the order of the first state to the fourth state, the flow direction and amount of the blown air flow are, for example, no wind, oblique direction away from the first intake port, It will change regularly in order of the front direction and the diagonal direction which leaves | separates from a 2nd inlet port.

  Therefore, the air blowing device of this aspect can regularly adjust the flow direction and amount of the blown air flow, and can improve the ease of use of the air blowing device.

  Note that “closing” the first air intake port or the second air intake port can be paraphrased as prohibiting air from passing through the first air intake port or the second air intake port. Furthermore, “opening” the first intake port or the second intake port may be rephrased as permitting air to pass through the first intake port or the second intake port.

・ Aspect 2
In the air blowing device of the present invention, if the positional relationship between the first valve and the second valve is determined in consideration of the shape of the housing, the amount and directionality of the blown air flow required for the air blowing device, etc. Good, not particularly limited.

For example, the first valve and the second valve are:
The air outlet side end of the first valve and the air outlet side end of the second valve may be configured to rotate in conjunction with each other so as not to contact each other.

  According to the above configuration, even when the first valve and the second valve rotate simultaneously (for example, when the intake valve is in the third state), the rotation of one intake valve is the other intake valve. Does not interfere with the rotation. Therefore, compared to the case where the first valve and the second valve are in contact, the flow direction of the blown air flow can be adjusted in a wider range, and the directivity of the blown air flow can be further improved.

  Hereinafter, an embodiment of an air blowing device of the present invention will be described with reference to the drawings.

<Outline of device>
FIG. 1 shows a schematic configuration of an air blowing device 10 (hereinafter referred to as “implementing device 10”) according to an example of an embodiment of the present invention. Specifically, the execution device 10 has a hollow columnar shape (tubular shape) through which an air flow can pass, and FIG. 1 is implemented by a plane parallel to the axis AX of the execution device 10. The schematic sectional drawing of the implementation apparatus 10 at the time of cut | disconnecting the apparatus 10 to the left-right direction (from the right direction R mentioned later to the left direction L) is represented.

  Hereinafter, for convenience, the direction toward the front and rear of the execution device 10 along the axis AX is also referred to as “front direction F” and “back direction B”, and the direction toward the left and right of the execution device 10 perpendicular to the front direction F is “left”. Also referred to as “direction L” and “right direction R”. The front, back, left, and right directions are the front, back, left, and right directions when the implementation device 10 is viewed from the vehicle operator when the implementation device 10 is installed in a vehicle interior or the like. Is defined on the basis of

  As shown in FIG. 1, the implementation apparatus 10 includes a housing (retainer) 21, a single wind direction adjusting plate (fin) 31, and a plurality of intake valves (dampers) 41 and 42. Hereinafter, the structure of these members will be described in more detail.

・ Case (Retainer)
The retainer 21 has a cylindrical shape (specifically, a substantially square cylindrical shape) in which an end portion in the front direction F is an open end and an end portion in the back direction B is closed. Furthermore, the retainer 21 has openings on the side surface in the right direction R and the side surface in the left direction L that allow the inside and the outside of the retainer 21 to communicate with each other. With these shapes, the retainer 21 has a first intake port 22 that opens to the side surface in the right direction R, a second intake port 23 that opens to the side surface in the left direction L, and an air outlet 24 that opens to the end in the front direction F. And an air flow path from the intake ports 22 and 23 to the outlet 24 is defined. In other words, the air taken into the retainer 21 from at least one of the first air inlet 22 and the second air inlet 23 by the retainer 21 passes through the air flow path and is then blown out from the air outlet 24. (See the arrow in the figure.) The end portion of the retainer 21 in the back direction B is closed by the back wall 25.

  The first intake port 22 and the second intake port 23 are arranged so as to face each other (that is, on the side surfaces 22 and 23 facing each other). Therefore, as shown in FIG. 1, when air is taken in from both the first air inlet 22 and the second air inlet 23, the air flow that passes through the first air inlet 22 and the air flow that passes through the second air inlet 23. And collide with each other inside or outside the retainer 21 to form a blown air flow (details will be described later). In addition, when air is taken in from only one of the first intake port 22 and the second intake port 23, the air flow collision and merging described above naturally do not occur.

  The first intake port 22 has a substantially rectangular shape (see, for example, FIG. 2). Further, the second air inlet 23 has a substantially rectangular shape that is the same as the shape of the first air inlet 22.

・ Wind direction adjustment plate (fin)
The fin 31 is a plate body having a substantially rectangular shape in plan view, and air (blown airflow) that passes through the outlet 24 according to an angle (rotation angle) when the fin 31 rotates around the rotation shaft 31a. The flow direction can be changed. The fin 31 is provided inside the retainer 21 in the vicinity of the air outlet 24 so as to be rotatable around the rotation shaft 31a. The rotating shaft 31a is perpendicular to the axis AX of the retainer 21 (in this example, perpendicular to the axis AX of the retainer 21 and parallel to the left-right direction of the implementation device 10).

  FIG. 2 is a schematic cross-sectional view of the execution device 10 when the execution device 10 is cut in the vertical direction (from an upward direction U to a downward direction D to be described later) along a plane perpendicular to the axis AX of the execution device 10. Yes. The “upward direction U” and the “downward direction D” are directions that go upward and downward of the execution device 10 along the axis AX. Similarly to the above, when the execution device 10 is mounted in a vehicle interior or the like, It is defined based on the vertical direction when the execution device 10 is viewed from the operator.

  As shown in FIG. 2, the fin 31 can adjust the flow direction of the blown air flow A up and down (UD) by rotating around the rotation shaft 31a.

  In this example, the fin 31 is rotatable in the range from the first position P1 to the second position P2. Furthermore, the inner wall surface 26 in the upward direction U and the inner wall surface 27 in the lower direction D of the retainer 21 parallel to the rotation shaft 31 a of the fin 31 are in the vicinity of the air outlet 24, and the axis AX of the retainer 21 approaches the air outlet 24. Inclined to approach. Specifically, the fin 31 and the inner wall surface 26 are parallel when the fin 31 is in the first position P1, and the fin 31 and the inner wall surface 27 are parallel when the fin 31 is in the second position P2. The inner wall surfaces 26 and 27 are inclined.

・ Intake valve (damper)
As shown in FIG. 1, the damper includes a first valve (first damper) 41 and a second valve (second damper) 42. The first damper 41 is a plate body having a substantially rectangular shape in plan view, and has a plate shape capable of covering the first air inlet 22 (see FIG. 2). The second damper 42 is a plate body having a substantially rectangular shape in plan view, and has a plate shape that can cover the second air inlet 23. The shape of the second damper 42 is the same as the shape of the first damper 41. In FIG. 1, the cross sections of these plates are displayed. The first damper 41 is provided in the retainer 21 in the vicinity of the first air inlet 22 so as to be rotatable around the rotation shaft 41a. Similarly, the second damper 42 is provided inside the retainer 21 in the vicinity of the second air inlet 23 so as to be rotatable around the rotation shaft 42a.

  Specifically, the rotation shaft 41a of the first damper 41 is perpendicular to the rotation shaft 31a of the fin 31 and perpendicular to the axis AX of the retainer 21 (see FIG. 2). That is, the rotation shaft 41 a is parallel to the vertical direction (U · D) of the execution device 10. Further, the rotation shaft 41 a passes through the end of the first damper 41 on the back wall 25 side (back surface direction B). The rotation shaft 41a is provided in the vicinity of the side surface in the right direction R so that the first damper 41 can close the first intake port 22.

  Therefore, the first damper 41 rotates around the end (rotation shaft 41a) on the back wall 25 side and is at a rotation angle that closes the first intake port 22 (the angle α shown in FIG. 1 is zero). The air can be prohibited from passing through the first air inlet 22. Further, the first damper 41 permits air to pass through the first intake port 22 when the rotation angle is such that the first intake port 22 opens (when the angle α is greater than zero). Air can flow from 22 to the blower outlet 24 in a direction corresponding to the rotation angle α.

  Similarly, the rotation shaft 42 a of the second damper 42 is also perpendicular to the rotation shaft 31 a of the fin 31 and perpendicular to the axis AX of the retainer 21. That is, the rotation shaft 42 a is parallel to the vertical direction (U · D) of the execution device 10. Furthermore, the rotation shaft 42a passes through the end of the second damper 42 on the back wall 25 side (back surface direction B). The rotating shaft 42a is provided in the vicinity of the side surface in the left direction L so that the second damper 42 can close the second air inlet 23.

  Therefore, the second damper 42 rotates around the end (rotation shaft 42a) on the back wall 25 side and is at a rotation angle that closes the second air inlet 23 (the angle β in the figure is zero). When there is, it is possible to prohibit the passage of air through the second air inlet 23. Further, the second damper 42 permits air to pass through the second intake port 23 when the rotation angle is such that the second intake port 23 opens (when the angle β in the figure is greater than zero). 2 Air can flow from the air inlet 23 toward the air outlet 24 in the direction corresponding to the rotation angle β.

  The shape of the first damper 41 and the second damper 42 is such that the end of the first damper 41 on the outlet 24 side and the end of the second damper 42 on the outlet 24 side are in contact with each other when the dampers rotate. It is determined not to. Furthermore, the shapes of the first damper 41 and the second damper 42 are determined so that the end portion (end portion in the front direction F) of each damper on the air outlet 24 side does not contact the fin 31.

  As described above, the first damper 41 and the second damper 42 can open and close the first intake port 22 and the second intake port 23, and can adjust the flow direction of the blown air flow A in the left-right direction (LR). Furthermore, the 1st damper 41 and the 2nd damper 42 are connected via the link mechanism (illustration omitted), and can rotate in response to each other. The link mechanism may be appropriately configured so as to realize a rotation state described later, and the number, arrangement, connection method, and the like of the gears and the connecting rods are not particularly limited.

  Note that the rotation angles of the fins 31, the first damper 41, and the second damper 42 are determined by, for example, an operator directly operating each fin via an operation knob (not shown) or an instruction from the operator. In response to this, a motor or the like (not shown) provided on each fin is operated to enable operation.

  The above is the description of the outline of the execution apparatus 10.

<Actual operation>
Hereinafter, the actual operation of the implementation apparatus 10 will be described with reference to FIGS.
The implementation apparatus 10 adjusts the flow direction of the blown air flow by changing the rotation angle of the fins 31 and the rotation angles of the first damper 41 and the second damper 42. 3 to 6 are schematic cross-sectional views of the implementation device 10 when the implementation device 10 is cut in the left-right direction along a plane parallel to the axis AX of the implementation device 10 as in FIG. 1. For convenience, in FIGS. 3 to 6, the rotation angle of the fin 31 is maintained at a predetermined size.

  FIG. 3 shows the state of the blown air flow when the rotation angle α of the first damper 41 is zero and the rotation angle β of the second damper 42 is zero. In this case, the first damper 41 and the second damper 42 are in a state (first state) in which both the first intake port 22 and the second intake port 23 are closed. Therefore, since air does not pass through the first air inlet 22 and the second air inlet 23, air is not blown out from the implementation device 10.

  Next, FIG. 4 illustrates the blown air when the first damper 41 rotates until the rotation angle α reaches a predetermined magnitude larger than zero and the second damper 42 maintains the rotation angle β. Represents the state of flow. In this case, the first damper 41 and the second damper 42 are in a state (second state) in which only the first intake port 22 is opened. Therefore, only the air that has passed through the first air inlet 22 flows in a direction corresponding to the rotation angle α of the first damper 41, and is blown out from the air outlet 24 through the fins 31. Therefore, in this case, the blown air flow A is formed in a direction inclined from the front direction F to the left direction L.

  In the above case, the air that has passed through the first air inlet 22 is blown out from the air outlet 24 after contacting the fins 31 and the inner wall surface of the casing 21, so the inclination angle of the air flow A (angle γ in the figure) ) Does not necessarily coincide with the rotation angle α of the first damper 41. However, the inclination angle γ of the blown air flow A and the rotation angle α of the first damper 41 are generally the same size.

  Next, FIG. 5 shows a predetermined size in which the rotation angle α of the first damper 41 is larger than zero, and a predetermined size in which the rotation angle β of the second damper 42 is larger than zero (in this example, The rotation angle β is the same as the rotation angle α.) Represents a state of the blown air flow when the rotation angle β is rotated. In this case, the first damper 41 and the second damper 42 are in a state (third state) in which both the first intake port 22 and the second intake port 23 are opened. Therefore, the air that has passed through the first intake port 22 flows in a direction corresponding to the rotation angle α of the first damper 41, and the air that has passed through the second intake port 23 has the rotation angle β of the second damper 42. Flow in the corresponding direction. These airs merge after colliding inside or outside the casing 21 in the vicinity of the fins 31 and are blown out from the air outlet 24.

  In the above case, the inclination angle γ of the blown air flow A is determined based on the magnitude relationship between the rotation angle α of the first damper 41 and the rotation angle β of the second damper 42. For example, if the rotation angle α of the first damper 41 and the rotation angle β of the second damper 42 are the same as in this example, the blown air flow A is formed in the front direction F as shown in FIG. Is done. That is, the inclination angle γ is zero. On the other hand, if the rotation angle α of the first damper 41 is larger than the rotation angle β of the second damper 42, the blown air flow A is formed in a direction inclined to the left direction L from the front direction F. . Conversely, if the rotation angle β of the second damper 42 is larger than the rotation angle α of the first damper 41, the blown air flow A is formed in a direction inclined to the right direction R with respect to the front direction F. Become.

  Next, FIG. 6 illustrates the blown air when the first damper 41 rotates until the rotation angle α becomes zero again, and the rotation angle β of the second damper 42 has a predetermined magnitude larger than zero. Represents the state of flow. In this case, the first damper 41 and the second damper 42 are in a state (fourth state) in which only the second air inlet 23 is opened. Therefore, the air that has passed through the second air inlet 23 flows in a direction corresponding to the rotation angle β of the second damper 42, and is blown out from the air outlet 24 through the fins 31. Therefore, in this case, the blown air flow A is formed in a direction inclined from the front direction F to the right direction R.

  Note that, as described above, the inclination angle γ of the blown air flow A does not necessarily coincide with the rotation angle β of the second damper 42, but usually has the same magnitude as the rotation angle β of the second damper 42.

  Thus, when the 1st damper 41 and the 2nd damper 42 change in order of the 1st state, the 2nd state, the 3rd state, and the 4th state, the blowing air flow A is a windless state, left direction L, front direction F And it changes in the order of the right direction R.

  3 to 6 show the state of the blown air flow A when the rotation angle of the fins 31 is maintained at a constant size. However, as understood from the above description of the dampers 23, 24, if the rotation angle of the fin 31 changes, the flow direction of the blown air flow A changes in the vertical direction of the implementation device 10.

  For example, as shown in FIG. 2, when the fin 31 rotates in the upward direction U or the downward direction D, a blown air flow toward the downward direction D or the upward direction U is formed. Specifically, since the inner wall surfaces 26 and 27 of the housing 21 are inclined as described above, the air is guided toward the fin 31 and rectified by the fin 31, and then corresponds to the inclination of the fin 31. (See the arrow in the figure).

  When the fin 31 is in the first position P1, the fin 31 and the inner wall surface 26 are parallel to each other, so that the inner wall surface 26 not only guides air toward the fin 31 but also blows out by the inner wall surface 26 itself. The flow direction of the air flow is adjusted (directed toward the target flow direction). That is, when the fin 31 is in the first position P1, the air flow is rectified by both the fin 31 and the inner wall surface 26. On the other hand, when the fin 31 is in the second position P2, the air flow direction is rectified by both the fin 31 and the inner wall surface 27.

  As described above, the implementation apparatus 10 can adjust the amount and flow direction of the blown air flow A by including the retainer 21, the fins 31, and the dampers 41 and 42 described above. Therefore, even if the implementation apparatus 10 is a case where it installs in the place where back space, such as a ceiling part of a motor vehicle, or a pillar part, does not have allowances, it can fully exhibit the performance as an air blowing apparatus. In other words, the implementation device 10 can be installed without impairing the performance as an air blowing device even in a place where there is no room in the back space.

<Other aspects>
The present invention is not limited to the above embodiment, and various modifications can be employed within the scope of the present invention.

  For example, the housing 21 of the implementation apparatus 10 has a square cylindrical shape. However, the housing | casing 21 does not necessarily need to have a square cylindrical shape, and may have a cylindrical shape and other polygonal cylindrical shapes.

  Further, for example, the housing 21 of the implementation apparatus 10 has one opening on each of the right and left side surfaces (that is, the first intake port 22 and the second intake port 23 are defined). doing). However, the housing 21 may have a plurality of openings on each side surface. Further, the shape of the opening on the side surface in the right direction R and the opening on the side surface in the left direction L may not necessarily be the same, and may differ depending on the position where the implementation apparatus 10 is installed. Good.

  In addition, the implementation apparatus 10 is used by being attached to, for example, a ceiling portion of an automobile. However, the air blowing device of the present invention is not limited to a ceiling portion of an automobile, and can be attached to various members for which air supply or stop is desired (particularly, where there is no room in the back space).
