Description

  The present invention relates to an air outlet device disposed on a ceiling of a passenger compartment in order to send wind to occupants seated in a row in a vehicle left-right direction at a rear seat.

Patent document 1 is disclosing the air blower outlet apparatus arrange | positioned in the vehicle left-right direction both ends of a vehicle interior ceiling in order to send a wind to the passenger | crew of a rear seat (rear seat).

By the way, the air outlet apparatus disposed on the ceiling of the passenger compartment to send wind to the passengers in the rear seat has the following needs.
(A) It is desirable that wind at a predetermined speed (for example, 2 m / s to 4 m / s) can be directly applied to the occupant. The reason is that it becomes difficult for the occupant to obtain the comfort of being hit by the wind, whether the wind speed is too fast or too slow.
(B) It is desirable that wind can be directly applied to the throat of the passenger. The reason is that when the wind can only be applied to the area above the throat of the occupant, the wind hits the face (eyes) and head, and the occupant feels annoyed. This is because if the wind can only be applied to the clothes, it will be difficult for the occupant to obtain comfort due to the wind hitting the clothes.

However, the apparatus disclosed in Patent Document 1 has the following problems.
(A) Since the device is provided at the left and right end portions of the passenger compartment ceiling, wind at a predetermined speed (for example, 2 m / s to 4 m / s) is directly applied from the device to the right and left passengers of the rear seat. However, even if the direction of the wind blown from the device is directed toward the left and right center occupants of the rear seat, the distance from the device will be far, so the wind at a predetermined speed will be applied to the right and left center occupants of the rear seat. Difficult to hit directly.
It is also possible to increase the speed of the wind blown from the device (by changing it) so that the wind at a predetermined speed can be directly applied to the left and right passengers in the rear seat. However, it takes time and effort to change the wind speed.
(B) Since there is no description regarding the arrangement position of the apparatus with respect to the occupant, there is a possibility that the wind from the apparatus cannot be directly applied to the occupant's throat depending on the arrangement position of the apparatus.

JP 2010-89717 A

An object of the present invention is to directly apply wind at a predetermined speed not only to the left and right occupant throats but also to the left and right center occupant throats without changing the speed of the air blown from the device. An object of the present invention is to provide an air outlet device.

The present invention for achieving the above object is as follows.
(1) An air outlet device disposed on a ceiling of a passenger compartment to send wind to occupants seated in a row in the left-right direction of the vehicle at a rear seat,

A vehicle is located in front of the vehicle from a position where it does not directly hit the throat of A, and the vehicle is positioned behind the vehicle from a position where the wind at a predetermined speed cannot be directly applied to the throat of the vehicle occupant A because the distance from the throat of the vehicle occupant A is increased. And (b) the front of the vehicle from a position in front of the occupant B on the left side of the rear seat, where the wind from the device is blocked by the occupant B's face and head and does not directly hit the throat of the occupant B. A range B1 which is located behind the vehicle from a position where the wind at the predetermined speed cannot be applied directly to the throat of the occupant B because the distance from the throat of the occupant B increases; and (c) the rear Front of vehicle from occupant C in the left and right center of the seat Yes, the predetermined speed is obtained when the distance from the throat of the occupant C becomes farther forward than the position where the wind from the device is blocked by the occupant C's face and head and does not directly hit the throat of the occupant C. The air outlet device is arranged in a range where all of the range C1 that is behind the vehicle from the position where the wind cannot be directly applied to the throat of the occupant C overlap.
(2) having an actuator and a fin for adjusting the wind direction;
The air outlet device according to (1), wherein the direction of the fin can be changed by the driving force of the actuator.

  According to the air outlet device of (1) above, since the device is arranged in a range where all of the ranges A1, B1, and C1 in a state where the speed of the wind blown out from the device is constant, the device is separated from the device. It is possible to apply wind at a predetermined speed to the throat of each of the passengers A, B, and C in the rear seat by simply changing the direction of the wind blown from the device without changing the speed of the blown wind. it can.

According to the air outlet device of (1) above, the following effects can be further obtained.
Since the devices are arranged in a range where all of the ranges A1, B1, and C1 overlap, the devices can be arranged in one place on the ceiling of the passenger compartment. Therefore, it is not necessary to provide a plurality of ducts for guiding the wind to the apparatus or to provide a branching portion in the duct. Therefore, it is advantageous in terms of cost as compared with the case where a plurality of ducts are provided or a branching portion is provided in the ducts.
In addition, since the devices can be collectively arranged at one place on the ceiling of the passenger compartment, only one device can be provided. In this case, the number of parts can be reduced compared to the case where a plurality of devices are provided, which is advantageous in terms of cost.

According to the air outlet device of (2) above, since the direction of the fin can be changed by the driving force of the actuator, the direction of the wind blown from the device is automatically cycled by the driving force of the actuator. Can be changed. Therefore, it is not necessary to manually change the wind direction.
Further, since the direction of the wind can be automatically changed periodically, the wind hitting the occupant can be changed to intermittent wind (wind sometimes hit). Therefore, compared with the case where the wind continues to hit the occupant, the wind hitting the occupant can be brought closer to the natural wind, and the occupant can feel comfort.

  Below, the air blower outlet apparatus of the Example of this invention is demonstrated with reference to drawings. In the figure, UP indicates the upper side of the vehicle, and FR indicates the front side of the vehicle.

As shown in FIGS. 1 and 2, an air outlet device (hereinafter also simply referred to as a device) 10 according to an embodiment of the present invention is for a vehicle. The vehicle on which the device 10 is mounted (arranged) may be a two-row seat vehicle, a three-row seat vehicle, or a vehicle having four or more rows of seats. The device 10 is disposed on the passenger compartment ceiling R in order to send wind to the passengers A, B, and C who are seated in a row in the left-right direction of the vehicle on a rear seat (rear seat) 50 for three persons. The rear seats 50 may be in any number of rows as long as they are in the second and subsequent rows.
The device 10 is connected to a duct 40 provided in the vehicle, and blows air (wind) flowing through the duct 40 into the vehicle interior.

  The apparatus 10 is a so-called swing register in which the direction of the fin for adjusting the wind direction can be changed by the driving force of the actuator. Although the structure of the apparatus 10 is not specifically limited, an example of the structure of the apparatus 10 will be described with reference to FIG.

As shown in FIG. 3, the apparatus 10 includes a panel 11 that is fixedly attached to the passenger compartment ceiling R, a housing 12 that is rotatably supported by the panel 11, and an actuator 13 that is attached to the panel 11. And a wind direction adjusting fin 14 attached to the housing 12 and capable of changing the direction by the driving force of the actuator 13.
In the example shown in FIG. 3, two housings 12 are provided on one panel 11, but only one housing 12 may be provided on one panel 11. Three or more may be provided in 11.
Further, the direction of the fin 14 may be changed by rotating the housing 12 with respect to the panel 11 by the driving force of the actuator 13, and the fin 14 is moved with respect to the housing 12 by the driving force of the actuator 13. It may be possible to change it.

Here, the arrangement position (mounting position) of the apparatus 10 will be described.
As shown in FIG. 7, the device 10 is disposed in a range S where all the ranges A1, B1, and C1 overlap in a state where the speed of the wind blown from the device 10 is constant.
The range A1 is in front of the vehicle from the occupant A on the right side of the rear seat 50, and is ahead of the vehicle from the position A2 where the wind from the device 10 is blocked by the occupant A's face and head and does not directly hit the occupant's throat. As the distance from the throat of the occupant A increases, the vehicle is behind the vehicle from the position A3 where the wind at a predetermined speed (for example, 2 to 4 m / s (including both ends), the same applies hereinafter) cannot be applied directly to the throat of the occupant A. This is the range.
Further, the range B1 is in front of the vehicle from the passenger B on the left side of the rear seat 50, and in front of the vehicle from the position B2 where the wind from the device 10 is blocked by the passenger's B face and head and does not directly hit the passenger's throat. This is a range from the position B3 where the wind at a predetermined speed cannot be directly applied to the throat of the occupant B because the distance from the throat of the occupant B increases.
Further, the range C1 is located in front of the vehicle from the occupant C at the left and right center of the rear seat 50, and is located in front of the vehicle from a position C2 where the wind from the device 10 is blocked by the occupant C's face and head and does not directly hit the occupant's throat. In this range, the distance from the occupant C's throat is longer and the vehicle is behind the position C3 where the wind at a predetermined speed cannot be applied directly to the occupant's throat.

The range A1 will be described. In addition, about range B1, C1, since it follows the description of range A1, description is abbreviate | omitted.

(I) The reason why the range A1 is in front of the vehicle from the occupant A is that if the range A1 is behind the vehicle from the occupant A, the wind from the device 10 hits the back of the occupant A, the back, etc. It is because it cannot touch A's throat.

(Ii) The reason why the range A1 is in front of the vehicle from the position A2 where the wind from the device 10 is blocked by the face and head of the occupant A and does not directly hit the throat of the occupant A This is to prevent adverse effects caused by being too close to the occupant A behind the vehicle.

(Iii) Range A1 is behind the vehicle from position A3 where it becomes impossible to directly apply wind at a predetermined speed (for example, 2 to 4 m / s) to the throat of the occupant A because the distance from the throat of the occupant A increases. The reason for this is to suppress adverse effects caused by the device 10 in front of the vehicle from the occupant A being too far away from the occupant A in front of the vehicle.

“Position A3” varies depending on the distance between the occupant A and the device 10, the amount of air blown out from the device 10 (flow rate), the angle of the fin 14 with respect to the passenger compartment ceiling R surface, and the like. A specific example will be described using.
The distance between the occupant A and the device 10 is 750 mm (condition 1), and the blowout amount (flow rate) from the device 10 is 90 m3 / h with the fin 14 fully open (0 °) (condition 2). The angle of the fin 14 is 70 ° in the direction of the occupant A from the fully open (0 °) to the vehicle rear side (condition 3), as shown in FIG. The air that passed through the extending duct 40 was blown out of the device 10 to examine whether or not wind of a predetermined speed (2 to 4 m / s) could be applied to the occupant A's throat. The reason for the condition (condition 1) that “the distance between the occupant A and the device 10 is 750 mm” is that the occupant A sitting on the rear seat 50 reaches the device 10 by reaching out. If it is a distance that is assumed to be a long distance and is further away, the occupant A seated in the rear seat 50 may reach out and reach the device 10, making it difficult to operate the device 10. Because there is.
As a result, a graph as shown in FIG. 5 was obtained. FIG. 5 is a graph of (wind velocity at the occupant's throat) − (angle from vertically below the air outlet device).
The following can be seen from FIG.
If the angle from the vertically lower side of the apparatus 10 to the rear of the vehicle is 53 ° or less, wind of a predetermined speed can be applied to the throat of the occupant A, but the angle from the lower vertical direction of the apparatus 10 to the rear of the vehicle is 53. If the angle is larger than 0 °, it is impossible to apply wind at a predetermined speed to the throat of the occupant A. That is, as shown in FIG. 6, if the angle from the vertically lower side of the apparatus 10 to the rear of the vehicle is 53 ° or less, the distance from the occupant A's throat to the apparatus 10 is short and the occupant A's throat has a predetermined speed. Although wind can be applied, when the angle from the vertically lower side of the device 10 to the rear of the vehicle is greater than 53 °, the distance from the throat of the occupant A to the device 10 is increased and the throat of the occupant A reaches a predetermined speed. It becomes impossible to hit the wind. Therefore, the position where the angle is greater than 53 ° is “position A3” under the above three conditions.

(Iv) As shown in FIG. 7, the range A1 exists in an arc shape (substantially including an arc shape) centered on the occupant A. In FIG. 7, the range A <b> 2 is not a true arc but a substantially arc having a major axis radius of 400 mm and a minor axis radius of 300 mm. The reason why the device 10 is mounted on the side of the occupant A is that This is because the passenger A may hit the ear of the passenger A and cause the passenger A to feel annoyance.

Next, the operation of the embodiment of the present invention will be described.
In the embodiment of the present invention, the device 10 is arranged in a range S (see FIG. 7) where all of the arc-shaped ranges A1, B1, C1 in a state where the speed of the wind blown out from the device 10 is constant. Therefore, only by changing the direction of the wind blown from the device 10 without changing the speed of the wind blown from the device 10, wind at a predetermined speed is applied to each of the throats of the passengers A, B, and C. You can guess.

Since the device 10 is arranged in the range S where all of A1, B1, and C1 overlap, the device 10 can be arranged in one place on the vehicle interior ceiling R. Therefore, it is not necessary to provide a plurality of ducts for guiding the wind to the apparatus or to provide a branching portion in the duct. Therefore, the material cost can be reduced as compared with the case where a plurality of ducts are provided, a branch portion is provided in the duct, and the like, and the cost can be reduced by simplifying the shape of the duct 40.
Moreover, since the apparatus 10 can be collectively arranged in one place of the vehicle interior ceiling R, it is possible to have only one apparatus 10. In that case, compared with the case where a plurality of apparatuses 10 are provided, the number of parts can be reduced, which is advantageous in terms of cost.

Since the direction of the fin 14 can be changed by the driving force of the actuator 13, the direction of the wind blown from the device 10 can be automatically and periodically changed by the driving force of the actuator 13. Therefore, it is not necessary to manually change the wind direction.
Further, since the direction of the wind can be automatically changed periodically, the wind hitting the occupant can be changed to intermittent wind (wind sometimes hit). Therefore, compared with the case where the wind continues to hit the occupant, the wind hitting the occupant can be brought closer to the natural wind, and the occupant can feel comfort.
