support portions

9 and 9 provided on the

side walls

8 and 8 of the retainer 2. Thereby, the damper plate 3 is supported so that rotation with respect to the retainer 2 is possible.

As described above, one surface (upper surface in FIGS. 2 and 3) of the damper plate 3 is an air intake member for taking in the air circulating through the ventilation duct D arranged in the roof portion R into the vehicle compartment. Two air guide plates are formed. Among these, the first air guide plate 23 is disposed on the upstream side along the circulation direction Z of the air flowing through the ventilation duct D, and the second air guide plate 24 is disposed on the downstream side along the circulation direction Z. Yes. Accordingly, the first air guide plate 23 and the second air guide plate 24 are formed in this order from the upstream side along the circulation direction Z of the air flowing through the ventilation duct D.

The first air guide plate 23 and the second air guide plate 24 are both formed in a curved shape facing the air circulation direction Z, and the height of the first air guide plate 23 is the second air. It is formed lower than the height of the guide plate 24.

It is taken into the first ventilation opening 6 of the retainer 2. At this time, since the height of the first air guide plate 23 is lower than the height of the second air guide plate 24, a part of the air flowing through the ventilation duct D is blocked by the first air guide plate 23. It is taken into the first ventilation opening 6 of the retainer 2. The air in the ventilation duct D flowing outside the first air guide plate 23 is directed to the second air guide plate 24 without being blocked by the first air guide plate 23, and is formed higher than the first air guide plate 23. The second air guide plate 24 is taken into the first ventilation opening 6 of the retainer 2 based on the curved shape of the second air guide plate 24.
As described above, the air flowing along the circulation direction Z in the ventilation duct D uses the difference in height between the first air guide plate 23 and the second air guide plate 24 in two stages to form the first ventilation opening 6 of the retainer 2. As a result, the air flow rate taken into the retainer 2 from the ventilation duct D can be made uniform over the entire length of the first ventilation opening 6.

As shown in FIG. 2, the outer grill 4 is formed in a rectangular shape larger than the retainer 2 so as to constitute the outer cover of the air blowing device 1, and a pair of

flat plate portions

25, 25 and both ends of each flat plate portion 25. The first connecting portion 26 and the second connecting portion 27 that connect the two are integrally formed. In the outer grill 4, corresponding to the first ventilation opening 6 of the retainer 2, a second ventilation opening 28 defined by the

flat plate portions

25, 25, the first connection portion 26, and the second connection portion 27 is formed. ing.
The outer grill 4 is attached to the retainer 2 on the side opposite to the damper plate 3 by so-called claw fitting. Claw fitting means that an elastic claw is formed on one member and a claw fitting portion is formed on the other member, and the elastic claw and the claw fitting portion are elastically connected to each other. It is a method of attachment. Such claw fitting is well known, and its description is omitted here.

In the outer grill 4, fitting holes 30 are provided in the inner side walls 29 of the first connecting portion 26 and the second connecting portion 27 (only the inner side wall of the first connecting portion 26 is shown) that connect the

flat plate portions

25, 25. 30 is formed. In each fitting hole 30, fitting pins 34, 34 of the surface grill 5 described later are fitted, whereby the outer grill 4 and the surface grill 5 are fixed to each other.
On the surface side of the first connecting portion 26, a knob mounting hole 31 that houses the circular portion 18 of the dial knob 16 and exposes the front surface of the circular portion 18 to the outside is provided. The knob mounting hole 31 has

regulation walls

31A and 31A (only one is shown in FIGS. 1, 2, 6, 7, 9, and 10), and the dial knob 16 has a knob mounting. In the hole 31, movement in the left-right direction in each drawing is restricted by each restriction wall 31A.

As shown in FIGS. 2 and 4, the surface grill 5 has a rectangular surface plate 32, and side walls 33 and 33 (see FIG. 4) extending from both side ends of the surface plate 32 include The fitting pins 34, 34 are formed to protrude outward. As described above, the fitting pins 34 and 34 are fitted into the fitting holes 30 and 30 formed in the

inner side walls

29 and 29 of the outer guru 4, whereby the outer grill 4 and the surface grill 5 are mutually connected. It is fixed to.

As shown in FIG. 4, a plurality of air rectifying rib plates 35 are erected on both sides of the rear surface of the front plate 32 in the front grill 5. The outer end face of each air rectifying rib plate 35 is in contact with the surface of each

flat plate portion

25, 25 of the outer grill 4, and the back surface of each front plate 32 and each flat plate portion corresponding to the height of each air rectifying rib plate 35. A gap is formed between 25 and 25.

The outer end of each air rectifying rib plate 35 extends to both side edges 36, 36 of the surface plate 32. In FIG. 4, the angle θ formed by the longitudinal extension line of the air rectifying rib plate 35A formed at the leftmost position and the longitudinal extension line of the air rectifying rib plate 35B formed at the rightmost position is 90 degrees. The above is designed (105 degrees in the example shown in FIG. 4).
The reason why the angle θ is designed to be 90 degrees or more is as follows. That is, the seat in the vehicle compartment is provided so as to be movable in the front-rear direction, but the position of the head of the occupant H when the occupant H sits with the seat seat moved to the foremost position and the seat seat most Considering the position of the head of the occupant H when the occupant H sits after moving to the rear position, the occupant H sits on the seat seat at the most forward position and sits at the seat seat at the most rear position. In any case, the angle θ is preferably set to 90 degrees or more in order to perform appropriate indirect ventilation to the occupant H.

By using the surface grill 5 having the surface plate 32 configured as described above, the air taken in from the ventilation duct D through the first ventilation opening 6 of the retainer 2 and the second ventilation opening 28 of the outer grill 4. Can be blown out from both sides of the air blowing device 1 in a wide range of 90 degrees or more by the air guiding action of each air rectifying rib plate 35.

Then, operation | movement of the air blowing apparatus 1 comprised as mentioned above is demonstrated. First, a state where air is not taken in from the ventilation duct D and indirect ventilation is not performed will be described with reference to FIGS.
In a state where indirect ventilation is not performed, the dial knob 16 is not operated, and the operation protrusion 20 of the dial knob 16 is positioned at the lower end in the knob mounting hole 31 as shown in FIG. When the dial knob 16 is not operated, the operating shaft 22 of the damper plate 3 is in a position in contact with one end (the lower end in FIG. 6) in the long hole 21 of the operating portion 19. In this state, as shown in FIGS. 6 and 7, the damper plate 3 closes the first ventilation opening 6 of the retainer 2. Therefore, the air circulating through the ventilation duct D is not taken into the air blowing device 1.

Subsequently, the case of taking in air from the ventilation duct D and performing indirect ventilation will be described with reference to FIGS. When air is taken in from the ventilation duct D and indirect ventilation is performed, the operation protrusion 20 of the dial knob 16 is rotated upward in FIG. Based on the turning operation of the dial knob 16, the actuating portion 19 is turned counterclockwise from the state of FIG. 6, and the actuating shaft 22 is caused by a cam guiding action by the long hole 21 accompanying the turning of the actuating portion 19. As shown in FIG. 9, the long hole 21 is moved to a position where it abuts against the other end (left end in FIG. 9). As the operating shaft 22 moves, the damper plate 3 gradually moves away from the first ventilation opening 6, and when the operating shaft 22 contacts the other end of the long hole 21, the first ventilation opening 6 is completely removed. Opened.

A state in which the first ventilation opening 6 of the retainer 2 is opened is shown in FIGS. In the state where the first ventilation opening 6 is opened, the first air guide plate 23 of the damper plate 3 is located on the upstream side in the circulation direction Z of the air circulating in the ventilation duct D, and the second air guide plate 24. Is located downstream in the air circulation direction Z.
In such a state, the air flowing along the circulation direction Z in the ventilation duct D uses the difference in height between the first air guide plate 23 and the second air guide plate 24 in two stages, and the first ventilation opening 6 of the retainer 2. As a result, the air flow rate taken into the retainer 2 from the communication duct D can be made uniform over the entire length of the first ventilation opening 6.

As described above, the air taken into the first ventilation opening 6 of the retainer 2 through the first air guide plate 23 and the second air guide plate 24 of the damper plate 3 further flows into the second ventilation opening of the outer grill 4. It is guided from 28 toward the back surface of the surface plate 32 of the surface grill 5. The air thus guided is the longitudinal extension line of the air rectifying rib plate 35A formed at the leftmost position among the air rectifying rib plates 35 and the longitudinal direction of the air rectifying rib plate 35B formed at the rightmost position. Based on the fact that the angle θ formed by the direction extension line is set to 90 degrees or more, the air guide action of each air rectifying rib plate 35 is widely blown from both sides of the air blowing device 1 in a range of 90 degrees or more. It becomes.

As described in detail above, in the air blowing device 1 according to the present embodiment, the air circulating through the ventilation duct D through the first air guide plate 23 and the second air guide plate 24 at the open position of the damper plate 3 is provided. The air is taken into the first ventilation opening 6 of the retainer 2 and further taken into the second ventilation opening 28 of the outer grill 4. Thus, the air taken into the second ventilation opening 28 of the outer grill 4 from the first ventilation opening 6 of the retainer 2 is formed between the surface plate 32 of the surface grill 5 and the

flat plate portions

25, 25 of the outer grill 4. The air rectifying rib plate 35 is blown out of the air blowing device 1 by the air guiding action.
At this time, each air rectifying rib plate 35 formed on the back surface of the surface plate 32 of the surface grill 5 forms a gap between the back surface of the surface plate 32 and the

flat plate portions

25, 25 of the outer grill 4. The air taken in through the first ventilation opening 6 and the second ventilation opening 28 flows from both sides of the air blowing device 1 along the inner wall surface of the interior material N constituting the roof portion R in the vehicle compartment, and in the direction of the arrow X and the window portion W. Since it has an air guiding action that blows in the direction of the arrow Y along the, it is possible to take in the air circulating through the ventilation duct D and blow out the air indirectly from both sides of the air blowing device 1 without performing a special operation. Become.

In addition, a plurality of air rectifying rib plates 35 are erected on both sides of the back surface of the front surface plate 32, and in each air rectifying rib plate 35, the longest extension line of the air rectifying rib plate 35A formed at the leftmost position is the most. Based on the fact that the angle θ formed by the longitudinal extension line of the air rectifying rib plate 35B formed at the right end position is set to 90 degrees or more, the first ventilation opening 6 of the retainer 2 and the second ventilation of the outer grill 4 The air taken in from the ventilation duct D through the opening 28 can be blown out from both sides of the air blowing device 1 in a wide range of 90 degrees or more by the air guiding action of each air rectifying rib plate 35.

Further, the air flowing through the ventilation duct D is first taken into the first ventilation opening 6 of the retainer 2 by changing the air flow direction based on the curved shape of the first air guide plate 23, and at this time, the first air guide Since the height of the plate 23 is set lower than the height of the second air guide plate 24, a part of the air flowing through the ventilation duct D is blocked by the first air guide plate 23 and the first ventilation opening of the retainer 2. 6 is taken in. The air in the ventilation duct D that flows outside the first air guide plate 23 is directed to the second air guide plate 24 without being blocked by the first air guide plate 23, and is formed higher than the first air guide plate 23. The second air guide plate 24 is taken into the first ventilation opening 6 of the retainer 2 based on the curved shape of the second air guide plate 24.
As described above, the air flowing through the ventilation duct D is taken into the first ventilation opening 6 of the retainer 2 in two stages using the height difference between the first air guide plate 23 and the second air guide plate 24. As a result, the air flow rate taken into the retainer 2 from the ventilation duct D can be made uniform over the entire length of the first ventilation opening 6.

Note that the present invention is not limited to the above-described embodiment, and various improvements and modifications can be made without departing from the scope of the present invention.
For example, in the air blowing device 1 according to the embodiment, the air rectifying rib plate 35 is fixedly formed on the back surface of the surface plate 32 of the surface grill 5, but the air rectifying rib plate 35 changes the air blowing direction. A variable configuration that can be freely changed may be used.
The first air guide plate 23 and the second air guide plate 24 are provided on the damper plate 3, but these guide plates may be formed inside the retainer 2. Further, the damper plate 3 is provided with two air guide plates, a first air guide plate 23 and a second air guide plate 24, and is configured to take in air from the ventilation duct D in two stages. The number of guide plates is not limited to two, and two or more air guide plates may be provided to take in air from the ventilation duct D in multiple stages.
Furthermore, although the air blowing apparatus 1 is arrange | positioned at the roof side part RS, it is not restricted to this, For example, even if arrange | positioned at the side wall part etc. in the vehicle interior in large vehicles, such as a one box car, Good.
Further, in the present embodiment, the range of air blown from both sides of the air blowing device 1 is set to a range of 90 degrees or more, but is not limited to this, and both sides of the air blowing device at an arbitrary angle. It is also possible to blow out air from.
