DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for controlling the direction of a flow of air blown out of a blower of an air conditioner of a motor vehicle.
The present invention relates to an automatic wind direction changing device for an air conditioner of an automobile, and a method of automatically changing the wind direction of an air conditioner of an automobile, which automatically changes up, down, left and right.

[0002]

2. Description of the Related Art Conventionally, as a device for automatically changing a wind direction of an air conditioner of a car, a high-grade high-grade car or the like is provided with a wind direction changing blade and a motor installed at an outlet of the air conditioner. There is already known a system in which the wind direction changing blades are automatically actuated to the left or right by operating a switch or the like to operate them. ing.

[0003]

The system described in the prior art, however, is not equipped with some low-grade vehicles with little additional functions, and
If you change the wind direction of the air conditioner when you ride in a car without the system and cool it, for example, in a hot summer, you can manually change the air direction of the air conditioner by moving the vane. Become.

When it is desired to adjust the body temperature by the degree of contact with the wind, if it is felt hot, it is comfortable if the wind of the air conditioner is directly applied to the body. However, if the user continued to hit the wind as it was, the body temperature could drop rapidly and the physical condition might be impaired.

For this reason, the wind direction is changed. At this time, the wind direction changing blades are moved by hand. If it is felt hot, the air of the air conditioner is blown to the body, and when the body temperature starts to decrease, the air direction of the air conditioner is changed again. It is troublesome and very inconvenient to repeat these operations frequently, and the comfort during riding is not very good. Also, during operation, the air conditioner's wind direction changing blades are noticed,
There were various problems in terms of safety.

The present invention has been made in view of these problems, and an object of the present invention is to provide an apparatus and a method for making it possible to drive comfortably even in a low-lade automobile.

Next, a fifth embodiment of the present invention will be described with reference to FIG. In the automatic wind direction changing device for a car air conditioner of this embodiment, the wind direction change bodies 2 and 2a
The base 1 and the fixed body 4 are the same as the automatic wind direction changing device for the air conditioner of the automobile described in the first embodiment, but the motor 2
Reference numeral 3 denotes an electric motor instead of a windmill as in the first embodiment. The motor 23 is fixed by a fixing portion 1e of the base 1, and the electric wire 8 is connected to the motor 23.

Next, a description will be given of a method of using the automatic wind direction changing device for a vehicle air conditioner of the fifth embodiment. First, the mounting method and the mounting position are the same as those of the automatic wind direction changing device for a vehicle air conditioner of the first embodiment. When this is used, the above-mentioned electric wire 8 is wired so as to be directly or indirectly connected to the battery of the automobile. Then, the prime mover 23 rotates, and the transmission device 5e, The wind direction change bodies 2 and 2a connected by 5f rotate. At that time, when the air conditioner is operated, the direction of the wind blown out from the outlet is changed by the wind direction change body as in the first embodiment. Will continue.

Further, if a plug having a shape to be inserted into the socket of the cigarette lighter is connected to the end of the electric wire 8, the plug can be easily connected to the battery simply by inserting the plug into the socket. I can do it.

Also in the transmission device, the same effects as those of the above embodiments can be obtained by incorporating a member such as a flexible shaft in addition to a gear or a belt for the purpose of transmission. Further, the motor is linked to the wind direction changing body by a transmission device so as to be interlockable, but if the transmission device is configured to be capable of disconnecting the interlocking state at an arbitrary position, the wind direction change can be stopped, which is the present invention. This is effective when it is not desired to change the wind direction even when the automatic wind direction changing device for a vehicle air conditioner is mounted in front of the wind outlet of the vehicle air conditioner. Also, gears and pulleys are used in the transmission from the prime mover to the wind direction changing body, but if the rotation ratio during transmission is converted in several stages, the speed of the wind direction changes in several stages. Can be adjusted. Further, when a motor is used as the prime mover, if the rotation speed of the motor is adjusted, the speed at which the wind direction changes can be adjusted. Further, the base is hollow, but may be frame. The automatic wind direction changing device for a vehicle air conditioner and the method for automatically changing the wind direction of a vehicle air conditioner are not limited to the above embodiments, and the shape and material of each member, The mounting position and the mounting direction of can be changed as appropriate.
