Abstract

PURPOSE:To prevent the reduction of an air flow quantity from a outlet port by arranging a fin rotating shaft so that the rotating axis thereof has an inclination angle which is smaller than that of a outlet port with respect to the direction rectangularly intersecting with an air delivery. CONSTITUTION:When the operating portion 163 of an operating lever 160 is caused to slide up and down with respect to the air delivery from an air conditioner via a supply duct 101 and an opening and closing door 14 is rotated, it is possible to adjust the discharge quantity of air from a outlet port 11. Further, when an adjusting lever 170 is moved vertically and horizontally, horizontal fins 21 are rotated vertically and vertical fins 22 are rotated horizontally, the discharge direction (d) of an air from a outlet port 11 can be adjusted vertically and horizontally. A rotation axis (e) formed by being tied to a fin rotating shaft 23 of the horizontal fins 21 is directed more upward than the inclination direction of the outlet port 11, and the discharge direction (d) from the outlet port 11. Therefore, when the discharge direction (d) from the outlet port 11 is in the peripheral side of a delivery direction (f), the interval between the horizontal fins is not changed from the conventional one. When the discharge direction (d) is directed downward at the time of space heating and the like, the interval between horizontal fins 21 becomes wide, and it is possible to obtain a sufficient discharge quantity.

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) An example of a conventional air conditioner outlet structure is shown in FIG. 7.

This conventional structure is used for automobile instrument panel 01
It was set up in the following, 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 orthogonal air blowing direction ob that is orthogonal to an air blowing direction Oa.

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

The fins 03 are each rotatably provided by a fin rotation shaft 04 and are connected to each other by a connecting member 05 so as to be interlocked.

The fin rotation axes 04 were arranged so that the rotation axis Od connecting the fin rotation axes O4 was substantially parallel to the direction of inclination of the air outlet 02.

(Problem to be solved by the invention) By the way, it is rumored that some insulators, lumens, and panels are tilted significantly with respect to the perpendicular direction of air blowing for design reasons (see Figure 7 and actual illustrations). Showa 55-103433
(See Figure 7 of the publication).

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 air outlet, for example, as shown by the arrow OC in FIG. When the fins are oriented in the direction opposite to the opening direction Of, the inclination angle of the fins with respect to the rotation axis (α in Figure 7) becomes smaller, so the gap between the fins becomes narrower and the amount of air blown is reduced. It was something that would become.

By the way, even when the number of fins is reduced and the fin inclination (11 degrees α) in Fig. 7 is reduced, there is still sufficient spacing fji.
However, if the number of fins is insufficient, the direction of the air outlet cannot be adjusted sufficiently, and the back of the air outlet becomes visible, which is not desirable.

(Means for Solving the Problems) The present invention has been made for the purpose of solving the above-mentioned problems, and to achieve this purpose, the present invention has the following features:
SkyrJ! An air outlet for blowing out the air from the J machine is opened at an angle with respect to a direction perpendicular to the air blowing direction, and a fin for adjusting the air blowing direction is provided at the air outlet in the direction of inclination of the air outlet. The fins are arranged in rows, and each of the fins is provided to be rotatable by a fin rotation shaft, and connected to be rotatable in conjunction with a connecting member, and the fin rotation shaft is
In an air conditioner outlet structure in which a rotational axis connecting fin rotational axes is arranged in a substantially straight line, the rotational axis has a tilt angle smaller than the inclination angle of the outlet with respect to a direction perpendicular to the air blowing direction. The fin rotation shaft is arranged at the top.

(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 (nearly perpendicular) and the distance between the fins is widened.

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

Incidentally, in explaining the embodiment, a case where the present invention is used in an automobile air conditioner will be taken as an example.

First, a first embodiment shown in FIGS. 1 to 5 will be described.

The outlet structure of the air conditioner according to the first embodiment of the present invention has an outlet frame 10 and a grille 20 as its main components, as shown in FIG.

The grille 20 adjusts the blowing direction of the adjusted air blown from the air conditioner (not shown) through the blower duct 101, and as shown in FIG. The air outlet frame 10 is provided on the outlet frame 10 a little further back, and includes horizontal fins 21 arranged in rows in the vertical direction and vertical fins 22 arranged in rows in the left-right direction.

The horizontal fin 21 adjusts the air blowing direction d from the air outlet 11 in the vertical direction, and as shown in FIG. are arranged along the slope of

Further, as shown in FIGS. 1 and 2, this horizontal fin 21 has both left and right ends connected to fin rotation shafts 23 and 23, respectively.
A rotation shaft that is provided to be rotatable in the vertical direction, and whose left and right ends are connected to the fin rotation shaft 23!
Two connecting members 24 and 24 arranged in parallel to 1e are connected so as to rotate in conjunction with each other.

In addition, the fin rotation shaft 23, as shown in FIG.
The rotation axis e is arranged such that the angle of inclination of the air outlet 11 is smaller than the angle of inclination of the air outlet 11 with respect to the direction g orthogonal to the air blowing direction.

Note that the air blowing orthogonal direction g refers to a direction orthogonal to the air blowing direction f in the outlet frame 10.

Further, the vertical rotation of the horizontal fins 21 is regulated by stopper surfaces 12 and 12 formed at both upper and lower rear ends of the air outlet frame 10, as shown in FIG.

The vertical fins 22 are for adjusting the horizontal direction of the air blowing output direction d of the air outlet 11, and the vertical 2-in 22 is located at a position farther back than the horizontal fins 21, as shown in FIG. 1.2. They are arranged vertically in a row within the air outlet frame 10 of.

Further, as shown in FIGS. 1 and 2, the vertical fins 22 are provided such that their upper and lower ends are rotatable in the horizontal direction by rotation shafts 25 and 25, respectively.

The lower end portions are connected by a connecting member 26 and can be rotated in conjunction with each other.

The left and right rotation of the vertical fins 22 is regulated by stoppers 13 and 13 formed protruding from the left and right inner surfaces of the air outlet 10, respectively, as shown in FIG.

Further, the air outlet frame 10 is provided with an opening/closing door 14 on the side of the air blowing duct 101.

This opening/closing door 14 is for adjusting the amount of air blown from the air outlet 11, and as shown in FIGS. 1 and 2,
It is supported by the air outlet frame 10 so as to be rotatable in the vertical direction by link pins 15 and bins 16 fitted in both left and right ends,
Moreover, the air passage within the air outlet frame 10 is formed to be openable and closable.

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

The operating lever 160 is used to rotate the opening/closing door 14. The operating lever 160 is formed in a substantially dogleg shape, and the center portion is rotated to the left side of the air outlet frame 10. It is rotatably supported by a shaft 161, and its base end is connected to the connecting bin 150 through a slide groove 162 so as to be able to absorb back and forth positional movement, and its distal end is connected to the lever groove 17 of the outlet frame 1°. The operating portion 163 is projected from the inside toward the vehicle interior 103 side.

Further, this operating lever 160 has an arc-shaped rotation groove 164 vertically formed in the center thereof, and a stopper pin 18 fixed to the left side of the air outlet frame 10 is inserted into the rotation groove 164. The stopper pin 18 restricts rotation of the operating lever 160. Note that this rotation restriction position is formed to coincide with the fully closed position of the air passage of the opening/closing door 14.

Reference numeral 170 in the figure is an adjustment lever that serves as a handle for adjusting the inclination angle of both fins 21 and 22, and as shown in FIGS. The vertical fin 22 is inserted so as to be slidable in the direction, and the front end is locked to the vertical fin 22 at the center so as to be rotatable in the vertical direction. , the horizontal fin 21 is rotated vertically by vertical rotation.

Next, the operation of the embodiment will be explained.

For the air blown from the air conditioner via the air duct) 101,
By sliding the operating portion 163 of the operating lever 160 up and down and rotating the opening/closing door 14, the amount of air blown from the air outlet 11 can be adjusted.

In addition, by moving the adjustment lever 170 vertically and horizontally, and rotating the horizontal fins 21 vertically and the vertical fins 22 horizontally, the air blowing direction d from the air outlet 11 can be adjusted in the vertical and horizontal directions. can be adjusted to

By the way, in the air outlet structure of the first embodiment, when the horizontal fins 21 are directed downward as shown by the imaginary line in FIG.
When the horizontal fins 21 are rotated in the opposite direction (downward) from the opening direction (upward) with respect to the air blowing direction f], the interval between the horizontal fins 21 is naturally the maximum interval (the horizontal However, as shown in FIG. The distance t2 is wider than the distance t2 when facing downward at the same angle to the blowing direction f in a parallel structure (right side in FIG. 5).

This is due to the reasons described below.

As shown in FIG. 5, the interval t between the horizontal fins 21 is It is expressed as t=to.5lnO.

(to=rotation - distance between 11, 0=angle of inclination of horizontal fin 21 with respect to 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 rotation axis kQ is formed by connecting the fin rotation axes 23 of the horizontal fins 21.
By adopting a structure in which e is directed upward than the inclination direction of the air outlet 11, the air blowing direction d from the air outlet 11 is different from the conventional one in the vicinity of the air blowing direction 1, which is a frequently used range. Without this, when the blowing direction d is directed downward during heating or the like, the interval between the horizontal fins 21 becomes wider than before, and a sufficient amount of blowing air can be obtained.

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 fin 200 is connected to the fin rotation shaft 210.
In this example, the horizontal fins are arranged parallel to each other, 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 sloping part of the instrument panel, but it may also be provided in a part other than the instrument panel, such as below, in a part slanting in the left and right direction, or in a part other than the instrument panel. However, the present invention is not limited to horizontal fins provided in the horizontal direction.

Further, in the embodiment, in addition to the horizontal fins arranged in the inclination direction of the air outlet, vertical fins arranged in a direction orthogonal to the horizontal fins are also provided, but it is not necessary to provide these vertical fins.

Furthermore, the air outlet may be provided in another member, such as an instrument panel, instead of in the air outlet frame.
Support for the fins may also be provided 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 with respect to the rotation axis is larger (almost perpendicular) and the distance between the fins becomes wider. This provides the effect that reduction in the amount of air from the outlet can be prevented without reducing the number of fins.

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