Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a register used for indoor air conditioning where design is important, and is used in ships and vehicles, particularly automobiles.

[Conventional technology]

It has been known for a long time to use a register to air-condition the interior of an automobile, and to send airflow for heating, cooling, and ventilation in appropriate directions.The conventional register, as shown in FIG.
Inside, 12 groups of horizontal fins and 13 groups of vertical fins are arranged in a grid pattern, and by vertically moving the horizontal fins, the wind direction can be adjusted vertically, and by rotating the vertical fins horizontally, the wind direction can be adjusted horizontally. There is. The horizontal fins 12 arranged in parallel at regular intervals are configured to rotate in the same manner by a vertical connecting rod 16, and are adjusted by a horizontal fin adjustment dial 14. Further, each of the vertical fins 13 is configured to rotate in the same manner by a horizontal connecting rod 17, and is adjusted by a vertical fin adjustment dial 15.

[Problem that the invention seeks to solve]

For conventional registers with the structure described above,
A vertical and horizontal lattice is formed by the vertical fin group and the horizontal fin group, and holes are formed in the lattice, which spoils the design of the instrument panel when applied to an automobile. Moreover, the vertical width of the air outlet could not be made thin, and dust adhered to each fin, making it difficult to clean. As a result, registers have become a major stumbling block in the design of luxury car interiors.

[Means for solving problems]

The present invention has a form in which air is blown out from horizontally elongated slits, and the register has a thinner vertical width than conventional products, reducing the area occupied by the register in, for example, an automobile instrument panel and expanding the design area of the panel. At the same time, the fins are not exposed, thereby solving the problems of conventional registers.
As shown in FIG. 1 and FIGS. 2A, 2B, and 2C, the internal fins 7 and 7' are concealed by the front ends 2 and 4 of the upper and lower plates 1 and 3, respectively, constituting the register housing, and each front end A downward guide surface and an upward guide surface 2', 4' for guiding airflow are formed on the inner side of the section, and a horizontal partition plate 5 having the same thickness as the slit S is provided near the slit S serving as a register outlet. is fixedly disposed, and a damper 6 is provided at the inner end (rear end) of the plate 5 so as to be rotationally adjustable by manual operation.
Also in the space between the horizontal partition plate 5 and the upper and lower plates, the upper and lower corresponding vertical fins 7, 7' are integrally connected by the vertical connecting rod 9, and the upper and lower pairs of fin groups are arranged at appropriate intervals. All the vertical fins are connected by a horizontal connecting rod 8, and the horizontal connecting rod is moved left and right by manual operation from the outside, thereby making it possible to adjust the rotation of each fin.

[Effect]

By moving the horizontal connecting rod 8 left and right using a conventional operating means, the upper and lower vertical fins 7 and 7' are moved left and right to adjust the direction of the air flow blown out from the space between the upper and lower plates and the horizontal partition plate to the left and right. Now I can do it. Further, by vertically moving the damper 6 around the pin P by conventional manual operation, the blown air flow could be adjusted vertically as shown in FIGS. 3a, b, and c.

When the register is viewed from the outside, that is, when a person inside the car views the register, the upper and lower vertical fins 7, 7' are hidden by the front ends 2, 4 of the upper and lower plates. , as if the front end of the top plate 2
It appeared as if only the horizontal partition plate 5 existed inside the slit space between the front end portion 4 of the lower plate and the front end portion 4 of the lower plate.

[Example] Example 1 As is clear from Fig. 1 and Fig. 2A, an upper plate having a downwardly bent portion 2 at its front end, a lower plate having an upwardly bent portion 4 at its front end, and a lower plate having a downwardly bent portion 4 at its front end. A register housing was formed by attaching and fixing a horizontal partition plate 5 having a substantially spindle-shaped cross section with curved guide surfaces 5' on the upper and lower edges to a side wall (not shown). Incidentally, slopes 2', 4' for guiding air flow are formed inside each bent portion 2, 4 of the upper and lower plates, and each slope 2', 4' and each curved surface 5',
5', and the width of the slit S formed between the upper and lower bent portions 2 and 4 is approximately equal to the vertical thickness of the horizontal partition plate 5. As such, the relationship structure between the upper and lower plates and the horizontal partition plates was determined.

At the rear end of the horizontal partition plate 5, a damper 6, which can be moved up and down by a pin P, is disposed across the left and right sides of the register, and the up and down movement of the damper 6 can be controlled from the outside by manual operation of a lever or dial. It was attached by conventional means (not shown) to achieve this goal.
In the space between the upper surface of the horizontal partition plate 5 and the inner surface of the upper plate, and in the space between the lower surface of the horizontal partition plate 5 and the inner surface of the lower plate, a group of upper vertical fins 7 and a group of lower vertical fins 7' are arranged in parallel at regular intervals, respectively. At the same time, the upper and lower pairs of fins are connected by vertical connecting rods 9 and pivotally supported by the upper and lower plates, and each connecting rod 9 is used as the rotation axis of the fins passing through the horizontal partition plate 5, so that each fin group can be connected to one fin group. The front lower end of the lower fin is connected by a horizontal connecting rod 8 so that it can be rotated by an adjustment tool, and the left and right adjustment movement of the horizontal connecting rod 8 can be achieved from the outside by manual operation of a lever or dial using conventional means. (not shown).

The function of the register in this embodiment is shown in Fig. 3a, b,
As shown in Fig. c, if the damper 6 is rotated upward around the pin P using a conventional dial or lever means (not shown) and brought into contact with the inner surface of the upper plate (Fig. a), the air conditioning air The flow is introduced only into the lower flow path _W2 between the horizontal partition plate 5 and the lower plate as indicated by arrow _A1 ,
The air was guided between the slope 4' on the inside of the front end of the lower plate and the lower curved surface 5' at the front end of the horizontal partition plate, forming an air flow A diagonally upward.

If the damper 6 is rotated between the neutral point (horizontal position) and the upper plate contact position (Figure b), the input airflow will be adjusted according to the cross-sectional area ratio between the upper and lower parts of the damper 6.
It is divided into A ₁ and A ₂ , and from the outlet, the flow rate in the lower flow path _W2 from below to diagonally upwards interacts with the flow rate in upper flow path _W1 from above to diagonally downwards to change the direction of the blowout. The applied airflow becomes A′. When the damper 6 is in the neutral position (horizontal position) (Figure c)
, the input airflow is divided equally up and down by the damper (A ₁ ,
A ₂ ) From the outlet, the flow rate from below to diagonally upward and the flow rate from above to diagonally downward were equal, so a horizontal blowout flow A'' was obtained.

In other words, the function of the horizontal blade group (blade group 12 in Fig. 4), which controlled the vertical adjustment of airflow in the conventional device, is that the function of the horizontal blade group (blade group 12 in Fig. 4) is that of each guide slope 2', 4' in front of the upper and lower plates. This can be achieved by using the blade plate 6, and from the front of the register, only the bent front ends 2 and 4 of the upper and lower plates and the front part of the horizontal partition plate 5 in the slit S between them can be seen, resulting in a novel appearance.

The blown air flow was adjusted in the left and right directions by moving the horizontal connecting rod 8 left and right by manually operating a conventional dial or lever, and by rotating the groups of upper and lower vertical blades 7 and 7' in the left and right directions.

Example 2 As shown in Fig. 2B, the horizontal partition plate 5 has a structure in which guide surfaces 5' are formed above and below the front end, and the rear end is provided with an arcuate concave surface R ₁ over the entire thickness, and the damper 6
It is formed into a wedge-shaped cross section that tapers from the base end and has an arcuate convex surface R ₂ that matches the concave surface R ₁ at the rear end of the partition plate, and has a thickness that is approximately the same as the _thickness of the partition plate. It is configured so that the convex surface _R2 is held and rotated.

The other rotating means for the upper and lower vertical fins 7, 7', the rotating means for the damper 6, the register casing, etc. were constructed in the same manner as in Example 1.

In this embodiment, the horizontal partition plate 5 and the damper 6 are in a relationship as if the body and the rear end warhead were separated from each other in the horizontal partition plate of Example 1. In addition to being able to reduce the space in the air flow direction between the damper and the damper by about half compared to that in Example 1, the air flow from the damper to the partition plate could always slide smoothly regardless of the damper's posture. It had the same effect as Example 1.

Example 3 As shown in Fig. 2C, the rear end of the horizontal partition plate 5 is formed into an arcuate convex surface _R3 , and the damper 6 is attached to the convex surface R3.
Curved plate part 60 with a concave surface _R4 matching _R3 on the inner surface
The other rotating means for the upper and lower vertical fins 7, 7', the rotating means for the damper 6, the register casing, etc. had the same structure as in Example 1, with the pin P disposed inside the horizontal partition plate.

In this embodiment, the rearward (windward facing) protrusion of the damper 6 can be made only by the thickness of the curved plate part 60, and the space in the air flow direction where the horizontal partition plate 5 and the damper 6 are connected can be minimized. It had the same effect as Example 1, except that it could be omitted.

〔others〕

When forming passages for fluids such as air, it is common technical knowledge to round corners and remove corners where the flow path is changed to prevent turbulence, vortices, etc., and to ensure smooth flow. , Example 2 (FIG. 2B) shows the application of the conventional means.

The inclination guide angle of each guide surface 2', 4' inside the outlet with respect to the horizontal axis is approximately 40 degrees to 40 degrees as shown in Fig. 2B in the case of an automobile slit register.
50° is suitable. This value is determined by the relationship between the distance from the register's outlet to the human body and the spray adjustment range relative to the human body, and the actual deflection value of the airflow from 70 to
As a result of examining the correlation with the phenomenon, it was found that this decreases to 80%.

Furthermore, as shown in FIGS. 2B and 2C, when the front edges of the upper and lower vertical fins are tilted backward, the vertical fins will no longer be visible even if you look diagonally inside the slit S from outside. Ta.

〔Effect of the invention〕

Since the horizontal fins are eliminated and the vertical fins are hidden by the front ends 2 and 4 of the upper and lower plates, a novel and luxurious register is obtained.

Because the register is thinner in the vertical direction,
The image of an air outlet has disappeared, and it can now be applied to places with limited space without sacrificing the design effect. In addition, when applied to automobiles, the instrument panel surface can be used in a wider range of design applications, increasing the degree of freedom in design.

Eliminating the horizontal fin group reduced the number of parts and streamlined manufacturing and maintenance management.
