BACKGROUND OF THE INVENTION
The present invention relates to a swing register of a vehicle air conditioner, and more particularly to a swing register of a vehicle air conditioner that can display the direction of air blown from the swing register of the air conditioner provided in the vehicle.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, in order to blow warm air or cold air from an air conditioner provided in an automobile into a passenger compartment, a swing register that can continuously change the wind direction using a motor or the like is generally used. Recently, a swing register that automatically controls the wind direction finely according to conditions such as the temperature environment inside and outside the vehicle interior and the degree of direct sunlight has come to be used. The swing register that automatically controls the wind direction has a structure that allows manual operation so that the wind can be directed in an arbitrary direction according to various occupant sensations, similarly to the conventional swing register.
[0003]
The structure for manual operation is roughly divided into a method in which the register blade is directed in a desired direction directly by manual operation or via operation knobs, and a direction of the blade by electric operation by operating a switch by an electric mechanism. There is a way to change. As an operation mechanism by manual operation, there is one shown in FIGS. (A) In the figure, the direction of the vertical blade 2 can be changed by the electric operation knob or the dial type operation knob 1, and (b) in the figure, the direction of the vertical blade 2 is determined by the slide type knob 3 that moves to the left and right. It can be changed. Reference numeral 4 denotes a swing switch for continuously swinging the vertical blade 2.
[0004]
FIGS. 5A and 5B are views showing an internal mechanism of an example of a manual operation mechanism by manual operation. FIG. 5A is a longitudinal sectional view, and FIG. This mechanism converts the rotation of the eccentric pin 6 attached to the output shaft of the geared motor 5 into a reciprocating motion at a constant angle by the link 7, and the reciprocating motion is converted to a gear 8 provided at the end of the link, a clutch 9, The vertical blade 12 is swung by a combination with the gear 11 provided at one end of the dial knob 10. In manual operation, the dial knob 10 can be rotated to an arbitrary position by the clutch 9 regardless of the rotation of the motor. The dial knob 10 and the vertical blade 12 can be rotated together.
[0005]
When the knob 1 shown in FIG. 4A is an electric operation knob, the electric operation knob 1 is interlocked with a switch. In the figure, if the front and right sides are pressed, the vertical blade 2 is rotated rightward by the motor, and if the left side is pressed, the vertical blade 2 is rotated leftward by the motor while being pressed. The blade swing state is released when the electric operation knob 1 is pressed.
[0006]
[Problems to be solved by the invention]
In the conventional swing register described above, the same is true of a general continuous swing register, but in the case of a register that changes the direction of the blade by a switch operation by an electric mechanism, the direction of the blade is now oriented. However, it was difficult for passengers to know how much the direction changed, and there was a problem that operability was poor.
[0007]
In view of the above-described conventional problems, an object of the present invention is to realize a swing register of a vehicle air conditioner in which the wind direction can be recognized at a glance.
[0008]
