Description

[Detailed explanation of the invention] A. Purpose of the invention (industrial application field) The invention is an air outlet for axle air conditioning. Specifically, the present invention relates to an air outlet with improved operability, durability, and performance by improving the material and structure of the inner case.

(Prior Art) Conventionally, a technique for fitting a male spherical grille to a female spherical grille attachment part in an air outlet for axle air conditioning was disclosed in Japanese Utility Model Publication No. 1798/1983.
Further, a technique for fitting a spherical outlet body into a spherical concave surface of a housing is known from Japanese Utility Model Application Publication No. 57-197314.

(Problem to be solved by the invention) Among the conventional techniques described above, the former involves attaching a seal ring to the male spherical surface of the grill mounting portion, fitting the male spherical surface of the grill into this, and sealing the gap between the mounting portion and the grill. Since it provides a sealing effect and an effect on the sliding movement of the grille, the seal ring retains its original shape and elasticity when new, and allows air direction changes and adjustments made by moving the grille to be performed reliably with appropriate resistance. After adjusting, stabilize the grill in the stopped position,
It will not be caused to move accidentally due to vehicle vibrations, etc. However, as the seal ring gets old, it collapses and loses its elasticity, causing the grill to move too lightly, making it even more difficult to adjust the orientation.Not only does it take time to adjust, but it also takes time and effort to finally set the orientation properly. Even though
If the axle vibrates, the direction changes, which causes the hassle of having to readjust it each time.Furthermore, a crushed seal ring can cause air leakage due to poor sealing, resulting in air loss and harsh noise. Furthermore, if the grille is tilted within the nozzle, increasing the angle of inclination will cause part b of the rear wall of the grille a to protrude into the nozzle c, as shown in Figure 4 of the drawings of this application. Since the opening area of c is reduced and a blind spot is created in the air blowing, not only is the amount of air blown out reduced, but there is also the problem that almost no air comes to the blind spot side, causing uneven air blowing that concentrates on the opposite side. be.

In addition, in the latter case, the outlet bodies are only fitted into the housing so that they are mutually formed into spherical surfaces, and there is no description of providing a sealing means between them, but if there is no sealing means, Since it is not possible to measure the sealing effect between the outlet body and the housing and the improvement in the sliding of the grille, it is currently recognized by those skilled in the art that a seal ring is used as a common means, and that there is no specific description. It was determined that the seal ring had the same problem as described above.
Also, since this outlet body is tilted within the housing, if the tilt angle is increased, the
As shown in the figure, a part e of the outlet main body d is hidden by the housing f, reducing the area of the opening and creating a blind spot in the air flow. This has the problem that the air stops flowing and the air blows unevenly, concentrating on the opposite side.

The present invention was made to solve the above-mentioned conventional problems.The spherical part of the soft inner case is inserted into the spherical seat of the outer case, and the hard pipe is press-fitted into the inner case. A new configuration that applies appropriate contact pressure to the seat allows you to easily and quickly set the desired blowing direction, without causing changes due to vehicle vibration, with a perfect sealing effect, and even when the blowing direction changes. It is an object of the present invention to provide an air outlet for vehicle air conditioning that has a constant air flow rate and does not cause uneven air flow regardless of the air flow.

B. Structure of the invention (means for solving the problem) The means of the invention for achieving the above-mentioned purpose is that a spherical part that fits the spherical seat is externally provided on a hard outer case in which a spherical seat is installed. A soft inner case is inserted, and a hard pipe is press-fitted into it to apply appropriate contact pressure between the spherical part and the spherical seat. Furthermore, an operating knob is attached to the front side of the inner case, and a bellows is attached to the rear side. The air outlet for air conditioning of a vehicle has a connecting part having a connecting part connected to the connecting part and a blowing pipe connected to the connecting part.

(Function) The air outlet of the present invention configured as described above has the following features:
A spherical portion 6 of an inner case 5 formed of a soft elastic material is attached to a spherical seat 2 provided inside the outer case 1.
When the spherical part 6 is deformed and housed, it will be elastically restored and fit into the spherical seat 2. Therefore, when the hard pipe 10 is press-fitted into the inner case 5 in this state,
The inner case 5, which is easily deformed because it is a soft elastic body, is held in a prescribed shape by the hard pipe 10, and the spherical portion 6 is pressed against the spherical seat 2, creating an appropriate contact pressure therebetween. Therefore, knob 12
When you move the inner case 5 by holding it and change the direction of air blowing, the inner case 5 moves as desired with an appropriate resistance, ensuring that the blowing direction is adjusted in one go, and the adjustment is easy. After that, in order to prevent the inner case 5 from moving unnecessarily due to the vibration of the vehicle due to the contact pressure between the spherical seat 2 and the ball part 6, the inner case 5 that has been set once is
The direction does not change unless it is changed manually, and furthermore, the inner case 5 is provided with a connecting part 9 having a bellows 7, and a blower pipe 8 is connected to this. When the inner case 5 is tilted, the air pipe 8 follows the tilt, maintaining a constant opening area regardless of the inclination, and there is no blind spot for air, so a constant amount of air is always distributed unevenly from the air outlet. It is something that can be blown out evenly without any problems.

(Example) An example of an air outlet for vehicle air conditioning according to the present invention will be described below based on the drawings.

In Figures 1 and 2 of the drawings, 1 is the outer case,
Made of hard and heat-resistant synthetic resin such as ABS, polypropylene, and polycarbonate, it is opened at the front and back and has a spherical seat 2 at the rear inside.
A rectangular mounting portion 3 as shown in FIG. 2 is provided at the front of the vehicle, and this portion is used to attach the vehicle to the wall surface 4 of the vehicle interior.

5 is an inner case made of a soft and elastic material such as polyethylene or soft polypropylene;
It is formed into a pipe shape as shown in the figure, and a spherical part 6 that fits the spherical seat 2 of the outer case 1 is formed on the outside thereof, and a connecting part 9 having a bellows 7 in the middle is formed on the rear side of this spherical part 6. However, the connecting portion 9 does not necessarily have to be integrally molded, and may be formed separately and connected by a hard pipe, which will be described later.

A hard pipe 10 is made of the same material as the outer case 1 and has a size to be press-fitted into the inner case 5, and the spherical portion 6 of the pipe 10 is deformed into the spherical seat 2 of the outer case 1. The pipe 10 is inserted into the housed case 5 to hold the inner case 5 in a prescribed shape, and presses the spherical portion 6 against the spherical seat 2 to generate an appropriate contact pressure between the two. An operating knob 12 is attached to the front part of the arm 11.

FIG. 3 shows another embodiment, in which outer cases 1, 1 having the same structure as the embodiment described above are arranged side by side for one mounting part 3, and inside these cases 1, 1, The structure accommodates the inner cases 5, 5 respectively, and operates both in the same manner as described above to individually adjust the blowing direction, and if necessary, three or more outer cases 1 may be arranged in parallel. Sometimes.

C. Effect of the invention In the vehicle air conditioning air outlet according to the invention, the inner case maintains its elasticity without collapsing even after long-term use, so the operation of adjusting the direction of air blowing by moving the inner case is always easy. It is possible to perform the operation reliably with appropriate resistance, and to set the air outlet in the desired direction in one go, and once the direction has been adjusted, it will not change due to vibrations of the axle, etc. It is very convenient for adjustment because it is held as it is without any air leakage, and the seal between the inner and outer cases is always perfect and does not leak air, so there is no possibility of air loss or harsh noise. Without,
Furthermore, since the spherical part is fitted into the spherical seat of the outer case, and the connecting part with bellows is connected to the rear part of the spherical part, and the air pipe is connected to this, the air duct will remain intact even if the inner case is tilted significantly relative to the outer case. Since this does not cause a change in the opening area or a blind spot in the air blowing, the air blowing amount is always constant regardless of changes in the blowing direction, and has the unique effect of not causing uneven air blowing.
