Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to the structure of an outlet for blowing air from an air conditioner.

(Prior art) For example, the outlet structure of a conventional air conditioner is as follows.
There is something like the one shown in Figure 7.

This conventional structure was provided in an instrument panel 01 of an automobile, and had the configuration described below.

An air outlet 02 that blows air from an air conditioner (not shown) to an instrument panel 01 is opened at an angle with respect to an air blowing direction 0b that is orthogonal to an air blowing direction 0a.

Fins 03 for adjusting the air blowing direction 0c are arranged in a row along the inclination of the air outlet 02.

The fins 03 each have a fin rotation axis 04
The connection member 0 is rotatably provided by the
5, they are interlockably connected.

The fin rotation shafts 04 were arranged so that a rotation axis 0d connecting the fin rotation shafts 04 was substantially parallel to the direction of inclination of the air outlet 02.

(Problem to be solved by the invention) By the way, inside the instrument panel,
For design reasons, there are some that have a large inclination with respect to the perpendicular direction of the air blowing (Fig. 7 and
(See Figure 7 of Publication No. 103433).

When such an instrument panel is provided with the conventional structure as described above, the following problems have occurred.

Normally, the air blown from the outlet on the instrument panel is often designed to hit the upper body of the occupant, but in particular, when heating, etc., it is desirable to direct the air from the air conditioner to the lower body and abdomen rather than the face. At this time, rotate the fins downward to change the direction of the air from the outlet, for example, as shown by the arrow 0c in FIG. When the fins are oriented in the direction opposite to the opening direction 0f), the inclination angle of the fins with respect to the rotation axis (α in Fig. 7) becomes smaller, so the gap between the fins becomes narrower and the amount of air blown out is reduced. It was something I got used to.

By the way, if you reduce the number of fins so that sufficient spacing can be obtained even when the inclination angle α of the fins in Figure 7 is reduced, the number of fins will be insufficient and the blowing direction will not be adjusted properly. However, there were problems in that the back of the air outlet could be seen, which was undesirable.

(Means for Solving the Problems) The present invention was made for the purpose of solving the above-mentioned problems, and in order to achieve this purpose, the present invention provides a blower that blows air from an air conditioner. The outlet is opened obliquely with respect to the orthogonal direction of the air blowing, which is orthogonal to the air blowing direction, and fins for adjusting the blowing direction of the air are arranged in a row in the inclination direction of the air outlet, and the fins are arranged to Each of the fins is rotatably provided by a fin rotating shaft, and is connected to be rotatably linked by a connecting member, and the fin rotating shaft is
In an air conditioner outlet structure in which a rotational axis connecting the fin rotational axes is arranged in a substantially straight line, the rotational axis has an inclination angle smaller than the inclination angle of the outlet with respect to a direction perpendicular to the air blowing direction. , the means in which the fin rotation shaft is arranged.

(Function) Therefore, in the air outlet structure of the air conditioner of the present invention, by using the above-mentioned means, when the fin is rotated in the direction opposite to the opening direction with respect to the air blowing direction, Compared to a structure in which the rotational axis is parallel to the direction of inclination of the air outlet, the inclination angle of the fins to the rotational axis is large (almost perpendicular) and the distance between the fins is wide.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

The lower end portions are connected to each other by a connecting member 26 so that they can rotate in conjunction with each other.

Note that the horizontal rotation of the vertical fins 22 is caused by the second rotation.
As shown in the figure, the air outlet 10 is regulated by stoppers 13, 13 that are formed protrudingly from the inner surfaces of both left and right sides of the air outlet 10, respectively.

Further, the air outlet frame 10 includes a blower duct 10.
An opening/closing door 14 is provided on the first side.

This opening/closing door 14 adjusts the amount of air blown from the air outlet 11, and as shown in FIGS. It is supported by the outlet frame 10 so as to be rotatable in the vertical direction, and is formed so that the air passage within the outlet frame 10 can be opened and closed.

As shown in FIGS. 2 and 3, the link pin 15 is formed integrally with a link member 140, and is connected to an operating lever 160 by a connecting pin 150 via the link member 140.

Next, the operation of the embodiment will be explained.

With respect to the air blown from the air conditioner through the air duct 101, the amount of air blown from the air outlet 11 is adjusted by sliding the operating part 163 of the operating lever 160 up and down and rotating the opening/closing door 14. be able to.

In addition, by moving the adjustment lever 170 up and down and left and right, and rotating the horizontal fin 21 in the up and down direction and the vertical fin 22 in the left and right directions, the air blowing direction d from the air outlet 11 can be adjusted in the up, down, left and right directions. can be adjusted to

By the way, in the air outlet structure of the first embodiment, the first
As shown by the imaginary line in the figure, when the horizontal fin 21 is directed downward [when it is rotated in the direction opposite to the opening direction (upward side) with respect to the air blowing direction f (downward direction)] , the spacing between the horizontal fins 21 is naturally smaller than the maximum spacing (the spacing when the horizontal fins are perpendicular to the rotation axis e), but
The interval t ₁ at this time is, as shown in Fig. 5, relative to the blowing direction f in a conventional structure in which the rotation axis e is parallel to the inclination direction a of the air outlet 11 (right side in Fig. 5). This is wider than the interval t ₂ when facing downward at the same angle.

This is due to the reasons described below.

As shown in FIG. 5, the interval t between the horizontal fins 21
is expressed as t=t ₀ ·sinθ.

(t ₀ = distance of the rotation axis, θ = angle of inclination of the horizontal fin 21 with respect to the rotation axis e) Therefore, when comparing the conventional structure and the structure of the embodiment (see FIG. 5), it is found that the horizontal fin 21 is moved downward. In this case, the value of sin θ becomes larger in the embodiment structure due to the smaller inclination angle of the rotation axis e, and the distance t between the horizontal fins 21 becomes larger.

Therefore, in the air conditioner outlet structure of the embodiment, the rotating axis e formed by connecting the fin rotating shafts 23 of the horizontal fins 21 is directed upward than the inclination direction of the outlet 11. , when the air blowing direction d from the air outlet 11 is around the air blowing direction f, which is a frequently used range, the interval between the horizontal fins 21 remains the same as before, but when the air blowing direction d is directed downward during heating, etc., the horizontal fins 21 21 is wider than before, and a sufficient amount of air can be blown out.

Next, a second embodiment shown in FIG. 6 will be described.

In describing the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals in the drawings, and the explanation thereof will be omitted. Furthermore, descriptions of the same functions will be omitted.

In this embodiment, the horizontal fins 200 are arranged parallel to the fin rotation axis 210, and the rotation axis e2 is formed to pass over the center of the short side of the horizontal fin.

Therefore, the conventional horizontal fin 200 can be used as is.

Although the embodiments of the present invention have been described above in detail with reference to the drawings, the specific configuration is not limited to these embodiments, and the present invention may be modified without departing from the gist of the present invention. included.

For example, in the embodiment, the air outlet is provided in an upwardly inclined part of the instrument panel, but it may be provided in a part other than the instrument panel and in a part inclined in other directions such as below or left and right. Then,
The fins are not limited to horizontal fins provided in the horizontal direction.

Further, in the embodiment, in addition to the horizontal fins arranged in the direction of inclination of the air outlet, vertical fins arranged perpendicularly to the horizontal fins are also provided, but the vertical fins may not be provided.

In addition, the air outlet is not an air outlet frame, for example,
The fins may be provided on other members such as an instrument panel, and the fins may also be supported by such other members.

(Effects of the Invention) As explained above, in the air conditioner outlet structure of the present invention, when the fin is rotated in the direction opposite to the opening direction with respect to the air blowing direction, the axis of rotation is Compared to a structure that is parallel to the direction of inclination of the air outlet, the operating angle (inclination) of the fins relative to the rotation axis is large (almost perpendicular) and the distance between the fins becomes wider. The effect is that the reduction in the amount of air from the air outlet can be prevented without reducing the number of fins.

Furthermore, since the arrangement of the fin rotation shafts is simply moved, the structure is simple and advantageous in terms of manufacturing and economy.
