Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a ventilation grill for an automobile air conditioner, and in particular to one that can effectively change the direction of airflow from side to side.

[Conventional technology]

Conventionally, when it is desired to change the direction of airflow in a ventilation grill for an automobile air conditioner, it is common to change the direction of the louver.

[Problem that the invention attempts to solve]

However, in conventional ventilation grilles, the louvers that control the wind direction are arranged almost on the same plane as the panel surface of the dash board, and as a result, it is extremely difficult to control the wind direction so that it is horizontal. Adjustment can be made to some extent by greatly changing the angle of the louver, but the area of the air blowing portion becomes smaller, the air volume decreases, and the air conditioning effect is halved.

[Means for solving problems]

The present invention has been made in consideration of the above-mentioned conventional problems, and includes a housing with an expanded outlet at the front, and a fitting section located around the inlet at the rear of the housing. The pull-out grill is provided with a pull-out grill that can be freely pulled out, and a louver that is disposed at the outlet of the housing and has an opening through which the pull-out grill can be inserted, and the pull-out grill has a communication hole that communicates with the inlet. a shutter portion that surrounds the hole and closes a flow path from the inlet to the louver when the louver is pulled out, and a control piece that laterally restricts the direction of the air that has passed through the communication hole and is exposed in front of the louver when the louver is pulled out. The present invention provides a ventilation grill for an automobile air conditioner consisting of the following, and solves the conventional problems.

[Effect]

In the present invention, the pull-out grill can be pulled out when necessary to adjust the wind direction laterally without reducing the air volume.

〔Example〕

The present invention will now be described in detail with reference to illustrative embodiments.

The figure shows a cross-sectional view of a ventilation grille 2 installed on a panel surface 1 of a vehicle. The ventilation grill 2 has an air inlet 2b on the rear side and an air outlet 2c that expands forward on the front side, and further has a guide member 2d formed near the inlet 2b, so that the external shape is improved. A substantially funnel-shaped housing 2a, a louver 3 disposed at the outlet 2c of the housing 2a, one end of which is slidably fitted into the guide member 2d, and the other end of which is an opening located at the center of the louver 3. It consists of a pull-out grille 4 that extends up to 3a.

The pull-out grille 4 has at one end a communication hole 4a (see FIG. 2) that communicates with the inflow port 2b and is surrounded by the shutter portion 4c in the central longitudinal direction, and has a communication hole 4a (see FIG. 2) surrounded by the shutter portion 4c at the other end. The structure includes a control piece 4b that laterally controls the air flow. And guide member 2
A fitting part 5 formed between d and the housing 2a
As described above, the shutter part 4c of the pull-out grille 4 is slidably inserted and integrated, and the air passing through the inlet 2b is guided to the louver 3 side by the control piece 4b. There is. Further, when the pull-out grille 4 is pulled out, the shutter portion 4c is connected to the inlet port 2b.
The control piece 4b is designed to close the air flow path from the louver 3 to the louver 3, and to expose the control piece 4b to the front side of the louver 3.

Therefore, when the pull-out grille 4 is inserted into the fitting part 5 as shown in FIG. 1, the air flowing through the communication hole 4a is directed toward the louver 3 by the control piece 4b. Instead, it is discharged from the outlet 2c. In this case, the wind direction is in the direction of the arrow, but by changing the direction of the louvers 3, it can be made slightly horizontal. Then, as shown in FIG. 2, when the pull-out grille 4 is pulled out to expose the control piece 4b, the air is blocked by the shutter portion 4c and does not flow to the louver 3 side. It will be discharged laterally at 4b. That is, the wind direction can be controlled laterally using the pull-out grille 4 as a guide.

In general, when the air from an air conditioner is applied directly to the human body, the effect can be doubled, and this effect is particularly noticeable when the temperature inside the car is high. According to this invented device, the direction of the wind can be changed significantly and the desired effect can be obtained.

[Effect of idea]

As explained above, the device according to this invention has a pull-out grill in the center of the louver that can control the wind direction laterally, and this pull-out grill can be stored freely, so the amount of air can be reduced. It is possible to control the wind direction horizontally without any problems, and the air conditioning effect can be doubled.

Also, by storing it when it is not needed, you can set the wind direction to the normal direction, which has the effect of allowing you to freely select it depending on the situation.
