Description

Description: TECHNICAL FIELD The present invention relates to a control device for an air conditioning outlet of an automobile, and more particularly to a control system when an automatic swing louver is provided at a plurality of air conditioning outlets.

(Prior Art) Generally, as shown in FIG.
One L1 and L4 are provided at the left and right ends in the vehicle interior width direction, and two L2 and L3 are provided near the center of the vehicle interior. With the supported wind direction adjusting vane, the direction of the air that is ventilated toward the occupant can be adjusted arbitrarily.

In recent years, at the air conditioning outlets L1 to L4, both ends L1 and 4 in the vehicle compartment width direction or the outlets L2 and L3 near the vehicle compartment are made to continuously swing by a drive source to adjust the left and right wind directions. It has been proposed to provide an automatic swing louver.

(Problems to be Solved by the Invention) However, although it is preferable that the air blowing is performed with a random cycle as close as possible to the natural wind, it is not possible to realize it simply by automatically swinging the wind direction. On the other hand, it is almost difficult to blow a random wind flow close to natural wind from the air conditioning outlet.

Therefore, it is an object of the present invention to skillfully utilize two types of automatic swing air blowing to realize random air blowing close to natural wind to an occupant.

(Means for Solving the Problem) According to the present invention, when the blast by the automatic swing is observed from the occupant position, the blast volume increases and decreases with a constant cycle. Therefore, if the blasts from two directions are merged by changing the cycle, It was made paying attention to the fact that the vector quantity of the wind can be changed at random intervals.The wind direction is provided at both left and right ends in the width direction of the passenger compartment and near the center of the passenger compartment, and is pivotally supported so that it can swing at least left and right. An air conditioning outlet that has adjustable blades and is configured to be adjusted so as to ventilate air toward the occupant. In the air outlets on the outside of the driver's seat and at least one of the outlets near the center of the vehicle A continuous right and left swing mechanism driven by a power source is attached to the adjusting blade body, and each swing mechanism can drive at least a pair of adjacent blades of the outlets at different swing cycles. The control unit of the air conditioner air outlet.

In the present invention, if a continuous left and right swing mechanism is attached to one of the air outlets on the outside of the driver's seat on the driver's seat side and one near the center of the vehicle compartment, and a manual left and right adjusting mechanism is attached to the remaining air outlets. Alternatively, a manual swinging mechanism and a continuous left-right swinging mechanism may be attached to all of the outlets to selectively set the continuous swinging position so that desired random air blowing can be performed.

Further, the rocking cycle of the continuous rocking mechanism can be controlled by using the rocking angle and / or the rocking speed as an adjustment factor, but since it is necessary to adjust two kinds of rocking cycles, each continuous rocking mechanism is It may be driven by an independent drive source, preferably an electric motor.

The phase difference between the two types of oscillating periods can be adjusted based on the random degree of combined blast.

(Operation) According to the present invention, as shown in FIG. 5, two kinds of blasts having different swing periods merge so as to intersect with each other. As a result, random blasting is possible, and the blasting mode changes momentarily. Therefore, it is possible to blow air close to natural wind in artificial air conditioning.

Hereinafter, the present invention will be described in detail based on specific examples shown in the accompanying drawings.

(Embodiment) FIGS. 1 to 3 are schematic front views of a dash panel of an automobile showing an aspect of a ventilation mode of an air-conditioning outlet provided with a control device according to the present invention, one at each of left and right ends in a vehicle width direction. The outlets L1 and L4 and the two outlets L2 and L3 are arranged near the center of the passenger compartment. In FIG. 1, the outlet L4 on the driver side outer side and the left outlet L2 near the center of the passenger compartment. A continuous left and right swing mechanism for the wind direction adjusting vanes driven by a power source is attached to the and, and the swing cycle is set to 10 seconds for L4, while L2 is adjusted to 9 seconds, while the outlet L1 outside the passenger seat is set. A manual left and right swing mechanism is attached to the right side outlet L3 near the center of the passenger compartment.

In this way, when a constant amount of air is blown while swinging the continuous left-right swing mechanism of the outlet L2 in the above-described cycle, the amount of air blown from the outlet L2 is observed from the driver side as shown in FIG. It changes as shown in the upper row. On the other hand, when a constant amount of air is blown while swinging the continuous left-right swing mechanism of the outlet L4 in the above-described cycle, the amount of air blown from the outlet L4 is 5th if observed from the driver side.
It changes as shown in the middle part of the figure.

Therefore, when both the above-mentioned airflows merge at the driver's position, the airflow rate changes randomly as shown in the lower part of FIG. In addition, in response to the change in the air flow, the outlet
One-way air flow from L3 may be appropriately added.

FIG. 2 shows a continuous left and right swing mechanism for the wind direction adjusting vanes driven by the power source, while the outlet L4 on the outside of the driver's seat and the right outlet L3 near the center of the passenger compartment are provided with the remaining outlets L1 and L1.
The case where a manual rocking mechanism is provided on L2 is shown. Further, FIG. 3 shows a continuous left and right swinging mechanism for the wind direction adjusting blade body driven by the power source at the outlet L4 on the outside of the driver's seat and the left and right outlets L2, L3 near the center of the passenger compartment The case where a manual rocking mechanism is provided at the air outlet L1 is shown. In addition, FIG. 4 shows a state in which one central air outlet is provided, and the air outlet on the driver side outer side is shown.
The L4 and the air outlet L5 near the center of the passenger compartment are provided with continuous left and right swing of the wind direction adjusting blade body driven by the power source, while the remaining air outlet L1 is provided with a manual swing mechanism. As the manual rocking mechanism, a conventionally known manual louver without a motor (for example, Japanese Utility Model Laid-Open No. 57-137945) may be adopted. A conventionally known automatic swing louver can be used as the continuous swing mechanism.

In the above embodiment, the continuous rocking mechanism and the manual rocking mechanism are arranged at predetermined positions, but the air conditioning outlets L1 to L4 can be used for both the left and right automatic rocking of the blade body and the manual rocking. A dynamic mechanism may be adopted, and by doing so, the continuous swing positions of the air conditioning outlets L1 to L4 can be arbitrarily set, for example, by selecting a switch, whereby the above-described FIGS. The ventilation mode shown in FIG. 4 can be realized. The mechanism shown in FIG. 6 may be adopted as a mechanism that can select continuous swing and manual swing of this kind. That is, in such a mechanism, the contact plate 51 and the contact 61
Is connected in parallel via lead wires L ₁ and L ₂ to a blade body drive circuit C1 composed of an electric motor M, a power supply S and a first switch SW1 so as to form a second switch SW2, and a manual adjustment circuit C2. Is formed. In the above configuration, when the operation knob 6 is set to the central position and the first switch SW1 is turned on, the rotation by the electric motor M is transmitted to the blade body 2 via the link mechanism, and the blade body 2 is moved to the swing shaft 21. While the center is designed to continuously swing right and left, when the first switch SW1 is turned off, when the blade body 2 reaches the center position, the non-conducting portion 52 of the contact plate 51 makes contact. The adjustment switch SW2 is turned off for the first time when it comes into contact with the child 61, so that the electric swing of the blade body 2 is stopped. Further, when the operation knob 6 is moved leftward or rightward, the contact plate 51 and the contactor 61 contact again,
When the adjustment switch SW2 is turned on, the blade body 2 swings to the left or right, and the contact plate 51 comes to a predetermined position, the adjustment switch SW2 is turned off and the blade body 2 is moved to the left by the movement amount of the operation knob 6. It swings in the direction and stops.

(Effects of the Invention) As is apparent from the above description, according to the present invention, the wind direction adjusting device is provided at both left and right ends in the vehicle width direction and near the vehicle center, and is at least pivotally supported for left and right swing. An air-conditioning air outlet that is equipped with blades and is configured to be ventilated toward the occupant. For the adjustment of each wind direction, the air outlet on the outside of the driver's seat and at least one air outlet near the center of the passenger compartment. A continuous left-right swing mechanism driven by a power source is attached to the blade body so that each swing mechanism can drive at least a pair of adjacent blades of the outlet at different swing cycles to control the air conditioning outlet of the automobile. As a result, when observing the blast by the automatic swing from the occupant position, the blast volume increases and decreases with a constant cycle, and the blasts from two directions merge by changing the cycle, resulting in a change in the wind vector quantity with a random cycle. It Rukoto can, blowing close to the natural wind is possible in the artificial air conditioning.
