Disclosure of Invention
Technical problem to be solved by the invention
In the air blowing device of patent document 1, the air blown out from the outlet port toward the rear of the vehicle tends to flow along the upper surface of the instrument panel due to the coanda effect. Therefore, even if the cold air is blown out from the outlet port in a state where the upper surface of the instrument panel is heated by the irradiation of sunlight, the cold air is heated by the instrument panel. This causes a problem that the temperature of the wind reaching the passengers is increased, and the comfort of the passengers receiving the wind is lowered.
The present invention has been made in view of the above problems, and an object thereof is to provide an air blowing device capable of suppressing heating of air blown out from an outlet port, and improving comfort of passengers receiving the air.
Means for solving the technical problem
An air blowing device according to an aspect of the present invention includes: an air outlet opening in an upper surface of an instrument panel of a vehicle; a baffle portion that can open and close the outlet and can guide the wind blown out from the outlet to the rear of the vehicle in a state where the outlet is opened; and a protruding portion that protrudes from the upper surface at least in a state where the air is blown out from the outlet at a rear end portion of the outlet located on a rear side of the vehicle, and an end portion of the baffle portion located on the rear side of the vehicle is located above the protruding portion at least in a state where the outlet is maximally opened.
In this configuration, the wind blown out from the outlet port and flowing toward the rear of the vehicle through the baffle portion is positioned at a position separated from the upper surface of the instrument panel by an amount corresponding to the projection height of the projection portion projecting from the upper surface of the instrument panel. Therefore, the wind directed rearward of the vehicle can be suppressed from flowing down the upper surface of the instrument panel. Namely, the occurrence of the coanda effect can be suppressed. This can suppress the cold air blown out from the outlet from being heated by the instrument panel, and can suppress the temperature of the air reaching the occupants of the vehicle to be low. Therefore, the comfort of the passenger receiving the wind can be improved.
In addition, the air outlet can be closed by the baffle portion, that is, the air outlet can be shielded by the baffle portion, in a state where air is not blown out from the air outlet. This improves the design of the upper surface of the instrument panel.
In the air blowout device described above, the protruding portion may be mounted so as to be rotatable with respect to the rear end portion of the outlet port between a 1 st position at which the protruding portion protrudes from the upper surface and a 2 nd position at which the protruding portion does not protrude from the upper surface and covers the outlet port.
In this configuration, the protruding portion is disposed at the 2 nd position in a state where air is not blown out from the outlet port, and thus the protruding portion can be prevented from protruding from the upper surface of the instrument panel. This can further improve the design of the upper surface of the instrument panel.
On the other hand, in a state where air is blown out from the outlet port, by disposing the protruding portion at the 1 st position, it is possible to suppress the wind flowing toward the rear of the vehicle as described above from running down the upper surface of the instrument panel.
In the air blowing device, the flap portion may be attached to be rotatable with respect to the outlet port about a rotation shaft extending in a width direction of the vehicle, and the rotation shaft may be located at a middle portion in a longitudinal direction of the flap portion extending in a radial direction of the rotation shaft.
In this configuration, the length of the baffle portion from the rotation shaft to the end of the baffle portion can be shortened as compared with a case where the rotation shaft is located at one end in the longitudinal direction of the baffle portion, and therefore, the rigidity of the baffle portion can be ensured. This can suppress, for example, the baffle portion from being deflected by the wind blown out from the outlet port, and thus can suppress the wind guided by the baffle portion from deviating in direction.
In the air blowing device, the plurality of baffle portions may be arranged in a front-rear direction of the vehicle.
In this configuration, the plurality of baffle portions can be operated independently of each other, and the wind blown out from the outlet port can be directed in various directions. For example, a part of the wind blown out from the outlet port can be guided to the rear of the vehicle by a part of the baffle portions, and the wind blown out from the outlet port can be guided to the windshield of the vehicle by the remaining baffle portions. That is, the function of blowing wind to the passenger and the function of the defroster (defrosting device) can be simultaneously exhibited.
Effects of the invention
According to the air blowing device of the present invention, since the air blown out from the outlet port can be suppressed from being heated, the comfort of the passenger receiving the air can be improved.

Detailed Description
[ embodiment 1 ]
Hereinafter, embodiment 1 of the present invention will be described with reference to fig. 1 to 3.
As shown in fig. 1, the air blowing device 1 according to the present embodiment is a device that blows air into a cabin 101 of a vehicle 100, and is provided in an instrument panel 102 of the vehicle 100. The instrument panel 102 is provided at a front end portion of a vehicle compartment 101 in the front-rear direction of the vehicle 100, that is, on the front side of a front seat 103 (driver's seat, passenger's seat). In vehicle 100 of the present embodiment, windshield 104 extends upward from the front end of instrument panel 102. A part of the windshield 104 is positioned above the instrument panel 102 with a gap therebetween.
In fig. 1 to 3, the front-rear direction of the vehicle 100 is shown in the X-axis direction. The vertical direction of the vehicle 100 is indicated by the Z-axis direction, and the width direction of the vehicle 100 is indicated by the Y-axis direction.
As shown in fig. 1 and 2, the air blowing device 1 includes an outlet 2, a baffle 3, and a protrusion 4.
The outlet 2 opens on an upper surface 102a of an instrument panel 102 of the vehicle 100. The outlet 2 is formed to blow out air output from an air conditioner (not shown) of the vehicle 100 toward the cabin 101 mainly above the instrument panel 102 (in the positive Z-axis direction). An arrow W1 in fig. 1 and 2 shows an example of the direction in which the wind blown out from the outlet 2 travels.
As shown in fig. 2 and 3, the flap 3 is provided to open and close the outlet 2. That is, the flap portion 3 is movably attached to the instrument panel 102 at a closing position P11 at which the outlet 2 is closed and at an opening position P12 at which the outlet 2 is opened. The flap portion 3 can guide the wind blown out from the outlet 2 in a state where the outlet 2 is opened, at least to the rear of the vehicle 100 (the X-axis positive direction).
The baffle portion 3 is formed in a plate shape. The flap 3 is attached to be rotatable with respect to the outlet 2 around a rotation shaft 5 extending in the width direction of the vehicle 100 in a direction orthogonal to the plate thickness direction.
In the present embodiment, the rotary shaft 5 is positioned at the front end 21 of the outlet 2, and the front end 21 of the outlet 2 is positioned on the front side of the vehicle 100. The baffle portion 3 extends only along one side of the rotation shaft 5 in the radial direction of the rotation shaft 5. That is, the rotary shaft 5 is located at one end in the longitudinal direction of the baffle portion 3 extending in the radial direction of the rotary shaft 5. Thus, the other end portion 32 in the longitudinal direction of the flap portion 3 located at a position spaced apart from the rotary shaft 5 in the radial direction of the rotary shaft 5 is located at the rear end portion 22 of the outlet 2 in the state where the flap portion 3 is disposed at the closed position P11, and the rear end portion 22 of the outlet 2 is located on the rear side of the vehicle 100. In the present embodiment, the other end portion 32 of the flap portion 3 is in contact with the tip end of the projection portion 4 described later in a state where the flap portion 3 is disposed at the closed position P11.
When the shutter portion 3 is moved from the closed position P11 to the open position P12, the shutter portion 3 may be rotated (rotated counterclockwise in fig. 2 and 3) so that the other end portion 32 of the shutter portion 3 is positioned above the projection portion 4 described later.
In the air blowing device 1 of the present embodiment, the direction of the air blown out from the outlet 2 guided by the flap portion 3 changes according to the rotation angle θ of the flap portion 3 with reference to the closed position P11. For example, as shown in fig. 2, when the rotation angle of the flap portion 3 is small, the wind blown out from the outlet 2 can be guided to the rear of the vehicle 100 through the flap portion 3 and reach the passenger 110 (particularly the face) of the vehicle 100 as shown by an arrow W1 in fig. 1 and 2. For example, as shown in fig. 3, when the rotation angle of the baffle portion 3 is large, the wind blown out from the outlet 2 can be guided upward by the baffle portion 3 and reach the windshield 104 (see fig. 1) as shown by an arrow W2. That is, the air blowing device 1 of the present embodiment has a function of blowing wind to the face of the passenger 110 and a function of a defroster (defroster) as the windshield 104.
For example, as shown in fig. 2, the shutter portion 3 is operated by an actuator 35 and a control portion 36. The actuator 35 is provided on the rotary shaft 5, for example, and rotationally drives the baffle portion 3. The controller 36 controls the operation of the actuator 35 so that the shutter portion 3 is disposed at a predetermined position. Further, the baffle portion 3 may be moved manually, for example.
As shown in fig. 2 and 3, the protruding portion 4 protrudes from the upper surface 102a of the instrument panel 102 at the rear end portion 22 of the outlet 2. The protruding portion 4 is formed so as to generate a step difference between the upper surface 102a of the instrument panel 102 and a region on the rear side (X-axis positive direction side) of the vehicle 100 with respect to the outlet port 2.
In the present embodiment, the protruding portion 4 protrudes in a direction (positive Z-axis direction) orthogonal to the upper surface 102a of the instrument panel 102. Also, the protruding portion 4 is formed integrally with the instrument panel 102. The protruding portion 4 may be formed separately from the instrument panel 102 and fixed to the instrument panel 102.
The end portion of the flap portion 3 located on the rear side of the vehicle 100, that is, the other end portion 32 of the flap portion 3, may be located above the protruding portion 4 in a state where at least the outlet 2 is maximally opened. In the present embodiment, in a state where the flap portion 3 is disposed at the closed position P11, the other end portion 32 of the flap portion 3 is placed on the tip end of the protruding portion 4. Therefore, the other end portion 32 of the shutter 3 is simply spaced apart from the front end of the projection 4, and the other end portion 32 of the shutter is located above the projection 4.
In the air blowing device 1 of the present embodiment configured as described above, by disposing the flap 3 at the open position P12 illustrated in fig. 2, the wind blown out from the outlet 2 can be guided rearward of the vehicle 100 through the flap 3. Here, the wind flowing toward the rear of vehicle 100 through baffle portion 3 is located at a position separated from upper surface 102a of instrument panel 102 by an amount corresponding to the projection height of projection portion 4 projecting from upper surface 102a of instrument panel 102. Therefore, the wind flowing toward the rear of vehicle 100 can be suppressed from running down upper surface 102a of instrument panel 102. Namely, the occurrence of the coanda effect can be suppressed. The protruding height of the protruding portion 4 may be set to a level that can suppress wind flowing toward the rear of the vehicle 100 from running along the upper surface 102a of the instrument panel 102.
This can suppress the cool air blown out from the outlet 2 from being heated by the instrument panel 102, and can suppress the temperature of the air reaching the passenger 110 of the vehicle 100 from being low. Therefore, the comfort of the passenger 110 receiving the wind can be improved.
In the air blowing device 1 of the present embodiment, the outlet 2 can be closed by the baffle portion 3 in a state where air is not blown out from the outlet 2, that is, the outlet 2 can be blocked by the baffle portion 3. This can improve the design of the upper surface 102a of the instrument panel 102.
In the air blowing device 1 of the present embodiment, the wind blown out from the outlet 2 can be directed toward the windshield 104 of the vehicle 100, depending on the position of the baffle portion 3. That is, the air blowing device 1 of the present embodiment not only has a function of blowing wind to passengers, but also can function as a defroster (defrosting device).
In embodiment 1, for example, as shown in fig. 4, the other end portion 32 of the flap portion 3 may enter the inside of the outlet 2 in a state where the flap portion 3 is disposed at the closed position P11, instead of being placed at the tip end of the protruding portion 4. In this case, the flap portion 3 can be disposed so that the flap portion 3 is parallel to the upper surface 102a of the instrument panel 102 in a state where the flap portion 3 is disposed at the closed position P11. This can further improve the design of the upper surface 102a of the instrument panel 102.
In embodiment 1, for example, as shown in fig. 5, the protruding portion 4 may protrude toward the front of the vehicle 100 (in the X-axis negative direction) as it goes upward from the upper surface 102a (in the Z-axis positive direction) of the instrument panel 102. That is, the protruding portion 4 may be inclined with respect to the vertical direction.
(embodiment 2)
Next, embodiment 2 of the present invention will be described with reference to fig. 6. In embodiment 2, the same components as those in embodiment 1 are denoted by the same reference numerals and the like, and descriptions thereof are omitted.
As shown in fig. 6, the air blowing device 1C of the present embodiment includes the outlet 2, the flap portion 3, and the protruding portion 4C, as in embodiment 1.
The flap 3 of the present embodiment is attached to be rotatable between a closed position P11 and an open position P12 with respect to the outlet 2 around the rotation shaft 5 located at the distal end portion 21 of the outlet 2, as in embodiment 1. However, in the present embodiment, the flap portion 3 disposed at the closing position P11 covers a part of the outlet 2. Specifically, the flap portion 3 disposed at the closing position P11 covers the portion of the outlet 2 on the distal end portion 21 side.
The protruding portion 4C of the present embodiment is attached to the rear end portion 22 of the outlet 2 so as to be rotatable between the 1 st position P21 and the 2 nd position P22.
The 1 st position P21 of the projection 4C is a position at which the projection 4C projects upward (in the Z-axis positive direction) from the upper surface 102a of the instrument panel 102. The protruding portion 4C may be disposed at the 1 st position P21 in a state of being blown out from the outlet 2. As illustrated in fig. 6, the protrusion 4C disposed at the 1 st position P21 may extend so as to be orthogonal to the upper surface 102a of the instrument panel 102, and may extend so as to be inclined with respect to the upper surface 102a, for example.
On the other hand, the 2 nd position P22 of the protruding portion 4C is a position where the protruding portion 4C does not protrude from the upper surface 102a of the instrument panel 102 and covers the outlet 2. The protruding portion 4C may be arranged at the 2 nd position P22 in a state where air is not blown out from the outlet 2. The protruding portion 4C disposed at the 2 nd position P22 covers a portion of the outlet 2 not covered by the aforementioned baffle portion 3.
The protruding portion 4C of the present embodiment is attached to be rotatable with respect to the outlet 2 around a rotation axis 7C extending in the width direction (Y-axis direction) of the vehicle 100 in the rear end portion 22 of the outlet 2.
According to the air blowing device 1C of embodiment 2, the same effects as those of embodiment 1 are exhibited. That is, by disposing the protruding portion 4C at the 1 st position P21 in the state where air is blown out from the outlet 2, the wind flowing toward the rear of the vehicle 100 can be suppressed from running along the upper surface 102a of the instrument panel 102.
Further, according to the air blowing device 1C of embodiment 2, in a state where air is not blown out from the outlet 2, the protruding portion 4C is disposed at the 2 nd position P22, whereby the protruding portion 4C can be prevented from protruding from the upper surface 102a of the instrument panel 102. This can further improve the design of the upper surface 102a of the instrument panel 102.
[ embodiment 3 ]
Next, embodiment 3 of the present invention will be described with reference to fig. 7. In embodiment 3, the same components as those in embodiment 1 are denoted by the same reference numerals and the like, and descriptions thereof are omitted.
As shown in fig. 7, the air blowing device 1D of the present embodiment includes the outlet 2, the baffle 3D, and the protruding portion 4, as in embodiment 1.
The flap 3D of the present embodiment is attached to be rotatable between a closed position P11 and an open position P12 with respect to the outlet 2 around a rotation shaft 5D extending in the width direction (Y-axis direction) of the vehicle 100, as in embodiment 1. However, in the present embodiment, the rotary shaft 5D is located at the middle portion of the outlet 2 in the front-rear direction (X-axis direction) of the vehicle 100. The baffle portion 3D extends in the radial direction of the rotation shaft 5D to both sides of the rotation shaft 5D. That is, the rotation shaft 5D is located at a middle portion in the longitudinal direction of the flapper section 3D extending in the radial direction of the rotation shaft 5D.
In a state where the flap portion 3D is disposed at the closing position P11, one end portion 31D of the flap portion 3D in the radial direction of the rotation shaft 5D is positioned at the front end portion 21 of the outlet 2, and the other end portion 32D of the flap portion 3D is positioned at the rear end portion 22 of the outlet 2. As illustrated in fig. 7, the other end portion 32D of the flap portion 3D disposed at the closing position P11 may enter the inside of the outlet 2 without being placed on the tip of the protruding portion 4, or may be placed on the tip of the protruding portion 4, for example. On the other hand, in a state where the flap portion 3D is disposed at the open position P12, one end portion 31D of the flap portion 3D is positioned below the outlet 2 (Z-axis negative direction), and the other end portion 32D of the flap portion 3D is positioned above the outlet 2 or the protruding portion 4 (Z-axis positive direction).
In the air blowing device 1D of the present embodiment, as in embodiment 1, the direction of the air blown out from the outlet 2 guided by the flap portion 3D changes according to the rotation angle of the flap portion 3D with reference to the closed position P11. That is, as illustrated in fig. 7, when the rotation angle of the flap portion 3D is small, the wind blown out from the outlet 2 can be guided to the rear of the vehicle 100 through the flap portion 3D and can reach the passenger 110 (see fig. 1) of the vehicle 100. On the other hand, when the rotation angle of the flap portion 3D is large, the wind blown out from the outlet 2 can be guided upward by the flap portion 3D and can reach the windshield 104 (see fig. 1). That is, the air blowing device 1D of the embodiment has a function of blowing wind to the face of the passenger 110 and a function of a defroster (defroster) as the windshield 104, as in embodiment 1.
According to the air blowing device 1D of embodiment 3, the same effects as those of embodiment 1 are exhibited.
Further, according to the air blowing device 1D of embodiment 3, the rotation shaft 5D is positioned at the middle portion in the longitudinal direction of the baffle portion 3D. Therefore, as compared with the case where the rotation shaft 5D is located at one end portion in the longitudinal direction of the baffle portion 3D as in embodiment 1, the length of the baffle portion 3D from the rotation shaft 5D to the end portions (one end portion 31D, the other end portion 32D) of the baffle portion 3D can be shortened, and therefore the rigidity of the baffle portion 3D can be ensured. This can suppress, for example, the baffle portion 3D from being deflected by the wind blown out from the outlet 2, and thus can suppress the deviation of the direction of the wind guided by the baffle portion 3D.
In the air blowing device 1D according to embodiment 3, for example, a configuration in which the protruding portion 4 is attached to be rotatable with respect to the outlet 2 as in embodiment 2 may be applied.
(embodiment 4)
Next, embodiment 4 of the present invention will be described with reference to fig. 8 to 10. In embodiment 4, the same components as those in embodiments 1 and 3 are denoted by the same reference numerals and the like, and descriptions thereof are omitted.
As shown in fig. 8 and 9, the air blowing devices 1E and 1F of the present embodiment include the outlet 2, the baffle portions 3 and 3D, and the protruding portion 4, as in embodiments 1 and 3. The baffle portions 3 and 3D of the present embodiment have the same functions as those of the first and second embodiments 1 and 3. However, the baffle portions 3 and 3D of the present embodiment are arranged in plural in the front-rear direction of the vehicle 100. The plurality of baffle portions 3 and 3D can operate in synchronization with each other. The plurality of baffle portions 3 and 3D operating in synchronization, for example, means that the plurality of baffle portions 3 and 3D face in the same direction. The plurality of baffle portions 3 and 3D can also operate independently of each other. The number of the baffle portions 3 and 3D is not limited to 2 in the example of the figure, and may be 3 or more, for example.
Each of the baffle portions 3 in the air blowing device 1E illustrated in fig. 8 is provided in the same manner as in embodiment 1. That is, each baffle portion 3 extends only to one side of the rotation shaft 5 in the radial direction of the rotation shaft 5. The end portion (the other end portion 32) of each flap portion 3 located at a position apart from the rotary shaft 5 in the radial direction thereof is located on the rear side of the vehicle 100 (the rear end portion 22 side of the outlet 2) with respect to the rotary shaft 5 in a state where the flap portion 3 is disposed at the closing position P11.
On the other hand, the flap portion 3D in the air blowing device 1F illustrated in fig. 9 and 10 is provided in the same manner as in embodiment 3. That is, each baffle portion 3D extends in the radial direction of the rotation shaft 5D to both sides of the rotation shaft 5D.
The air blowing devices 1E and 1F according to embodiment 4 exhibit the same effects as those of embodiments 1 and 3.
Further, according to the air blowing devices 1E and 1F of embodiment 4, the plurality of baffle portions 3 and 3D may be operated independently of each other, so that the wind blown out from the outlet 2 can be directed in various directions.
For example, in the air blowing device 1E shown in fig. 8, the rotation angle of the flap portion 3 located on the rear end portion 22 side of the outlet 2 is reduced, and the rotation angle of the flap portion 3 located on the front end portion 21 side of the outlet 2 is increased. Thus, a part of the wind blown out from the outlet 2 can be guided to the rear of the vehicle 100 by the partial flap 3, and the wind blown out from the outlet 2 can be guided to the windshield 104 of the vehicle 100 by the remaining flap 3.
In the air blowing device 1F shown in fig. 9 and 10, as shown in fig. 10, the 2 flap portions 3D arranged in the front-rear direction are rotated in opposite directions from the closed position P11 to be disposed at the open position P12. Specifically, the flap portion 3D located on the rear end portion 22 side of the outlet 2 is disposed such that the other end portion 32D is located higher than the protruding portion 4 or the upper surface 102a of the instrument panel 102. The flap portion 3D located on the front end portion 21 side of the outlet 2 is disposed such that one end portion 31D thereof is located higher than the upper surface 102a of the instrument panel 102. Thus, similarly to the case of the air blowing device 1E shown in fig. 8, a part of the wind blown out from the outlet 2 can be guided to the rear of the vehicle 100 by the partial flap 3D, and the wind blown out from the outlet 2 can be guided to the windshield 104 of the vehicle 100 by the remaining flap 3D.
Therefore, the air blowing devices 1E and 1F according to embodiment 4 can simultaneously perform the function of blowing the wind to the passenger 110 and the function of the defroster (defroster).
In the air blowing devices 1E and 1F according to embodiment 4, for example, a configuration may be applied in which the protruding portion 4 is rotatably attached to the outlet 2 as in embodiment 2.
While the embodiments of the present invention have been described above, the configurations and combinations thereof in the embodiments are examples, and additions, omissions, substitutions, and other modifications of the configurations can be made without departing from the spirit of the present invention. The present invention is not limited to the embodiments, but only by the claims.
