Abstract

PURPOSE:To obtain random air blasting approximate to a natural and by installing a power driving wind direction adjusting blade body continuous rocking mechanism additionally in at least one supply opening of both driver's seat outside and cab central part side supply openings, rocking it at a different period, and installing a manual longitudinal direction regulating mechanism in the remaining supply opening as well. CONSTITUTION:Each continuous longitudinal rocking mechanism consisting of an adjusting blade by power driving is additionally installed in a supply opening L4 at the outside of a driver's seat side and a left supply opening L2 in the vicinity of a cab central part, and the rocking period is varied separately at L4 and L2. For example, it is set 10 seconds at the L4 but 9 seconds at the L2 differently. Then, each longitudinal rocking mechanism by hand is additionally installed in respective supply openings L1 and L3. With this constitution, each air blasting out of both supply openings is joined together at the driver's seat owing to a difference in the blowoff period between these supply openings L4 and L2, and there is produced some random variation in a blasting quantity, and thereby such air blasting as approximating to a natural wind is secured so that amenity is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a control device for an air conditioner outlet of an automobile, and more particularly to a control system when automatic swing louvers are provided at a plurality of air conditioner outlets.

(Prior Art) Generally, the air conditioning outlet of an automobile is as shown in Fig. 1.
One Ll and L4 are provided at both left and right ends in the width direction of the passenger compartment, and two L2 and L3 are provided near the center of the passenger compartment. The structure is such that the direction of the wind directed toward the occupant can be arbitrarily adjusted by the supported wind direction adjustment blades.

In recent years, in these air conditioning outlets L1 to L4, vanes for adjusting the left-right direction of the air are continuously oscillated by a drive source at both ends Ll and 4 in the width direction of the vehicle interior or at the outlets L2 and L3 near the center of the vehicle interior. It is proposed to provide automatic swing louvers.

(Problems to be Solved by the Invention) However, although it is preferable that the air blowing by the air conditioner be carried out with a random cycle as close to natural wind as possible, this cannot be achieved simply by automatically changing the direction of the wind. However, it is almost difficult to blow a random flow of air close to natural wind from the air conditioner outlet.

Therefore, an object of the present invention is to skillfully utilize two types of self-oscillating air blowing to realize random air blowing close to natural wind to the occupants.

(Means for Solving the Problem) The present invention provides that when the air blown by automatic movement is observed from the passenger position, the amount of air blown increases and decreases with a certain period, so if the air blown from two directions is combined by changing the period, It was created by focusing on the ability to change the amount of wind vectors at random intervals, and is provided at both left and right ends in the width direction of the vehicle interior and near the center of the vehicle interior, and is pivotably supported to at least swing left and right. In an air conditioning outlet that is equipped with an adjustment blade and is configured to be adjustable so that ventilation is directed toward the occupants, power is applied to at least the outlet on the outside of the driver's seat side and at least one of the outlets near the center of the single room. A continuous left-right swing mechanism of the blade body for adjusting the wind direction by power source drive is attached, and the swing mechanism enables the above-mentioned blade body to be driven at different rocking cycles, while a manual left-right direction adjustment mechanism is provided for the remaining air outlets. This invention relates to a control device for an air conditioning outlet of an automobile.

In the present invention, a continuous left-right swing mechanism is attached to the air conditioning outlet on the outside of the driver's seat side and one near the center of the vehicle compartment, and the remaining outlets are provided with a manual left-right adjustment mechanism. However, it is also possible to attach a manual swinging mechanism and a continuous left-right swinging mechanism to all the air outlets, and to selectively set continuous swinging positions so that desired random air blowing can be performed.

In addition, the rocking period of the continuous rocking mechanism can be controlled by using the rocking angle and/or ° rocking speed as an adjustment factor, but since it is necessary to adjust two types of rocking periods, each continuous rocking mechanism is preferably driven by an independent drive source, preferably an electric motor.

The phase difference between the two types of rocking periods can be adjusted based on the randomness of the combined air blowing.

(Function) According to the present invention, as shown in FIG. 5, two types of air blowing with different oscillation periods join together in an intersecting manner, and as a result, random air blowing becomes possible, and air blowing close to natural air can be used in artificial air conditioning. It becomes possible.

Hereinafter, the present invention will be explained in detail based on a specific example I shown in the accompanying drawings.

(Example) Figures 1 to 3 are schematic front views of Dasonyu panels of an automobile showing aspects of the air blowing style of the air conditioning outlet equipped with the control device according to the present invention, one panel at each end of the left and right sides in the width direction of the vehicle interior. Air outlets Ll and L4 and two Suita outlets L2 and L3 are arranged near the center of the vehicle interior. A continuous left-right swing mechanism for the wind direction adjustment blade body driven by a power source is attached, and the swing period is set to L4.
is set to 10 seconds, while adjusting L2 to 9 seconds, the air outlet Ll on the outside of the passenger seat and the right air outlet L3 near the center of the passenger compartment
It is equipped with a manual left and right swing mechanism.

In this way, when a constant amount of air is blown while the continuous left-right swinging mechanism of the Suita outlet L2 is oscillated at the above-mentioned period, the amount of air blown from the air outlet L2 is as shown in FIG. 5 when observed from the driver's side. Changes as shown in the upper row.

On the other hand, when a constant amount of air is blown while the continuous left-right swing mechanism of the Suita outlet L4 is oscillated at the above-mentioned period, the amount of air blown from the air outlet L4 is as shown in the middle row of FIG. 5 when observed from the driver's side. It's changing.

Therefore, when the above-mentioned two air blowers merge at the driver's position, the air blowing amount changes randomly as shown in the lower part of FIG. 5. In addition, one-way ventilation from the Suita exit L3 may be appropriately added to the above-mentioned ventilation change.

Figure 2 shows that the air outlet L4 on the outer side of the driver's seat side and the right air outlet L3 near the center of the passenger compartment are provided with a continuous left-right swing mechanism for the wind direction adjustment blades driven by a power source, while the remaining air outlets Ll
and a case in which a manual movement mechanism is provided in L2 is shown. Also,
Figure 3 shows that the air outlet L4 on the outside of the driver's seat side and the left and right Suita outlets L2 and L3 near the center of the cabin are provided with a continuous horizontal swing mechanism for the wind direction adjustment blades driven by a power source, while the remaining air outlets are A case is shown in which a manual movement mechanism is provided at the exit Ll. In addition, Fig. 4 shows a state in which there is only one central air outlet, and the Suita outlet L4 on the outside of the driver's seat side and the air outlet L5 near the center of the passenger compartment have continuous left and right blades for adjusting the wind direction driven by a power source. While a swing mechanism is provided, a manual swing mechanism is provided at the remaining Suita exit L1.

As the manual movement mechanism, a conventionally known manual louver without a motor (for example, Japanese Utility Model Application No. 57-137945) may be employed. Moreover, a conventionally known automatic swing louver can be employed as the continuous swing mechanism.

In the above embodiment, the continuous rocking mechanism and the manual rocking mechanism are respectively arranged at predetermined positions, but the air conditioning outlet LL-L4
A rocking mechanism that can be used for both automatic and manual movement of the blade body to the left and right may be adopted for each, and in this way,
The continuous swinging positions of the air conditioning outlets Ll to L4 can be arbitrarily set, for example, by selecting a switch, thereby making it possible to realize the air blowing modes shown in FIGS. 1 to 4. A mechanism shown in FIG. 6 may be employed as a mechanism capable of selecting between this type of continuous rocking motion and manual rocking motion. That is, in such a mechanism, the contact plate 51 and the contactor 61 are connected to the electric motor M, the power source S, and the first switch SW.
A second switch S is connected to the blade drive circuit CI consisting of
They are connected in parallel via lead wires L1 and L2 to form a manual adjustment circuit C2. In the above configuration, the operating knob 6 is set at the center position, and the first
When the switch SWI 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 caused to swing continuously from side to side about the swing axis 21. On the other hand, when the first switch SW■ is turned off, when the blade body 2 reaches the center position, the non-conducting portion 52 of the contact plate 51 comes into contact with the contactor 61, and the adjustment switch SW2 is turned off for the first time. The electric movement of the blade body 2 is stopped. Furthermore, when the operating knob 6 is moved to the left or right, the contact plate 51 and the contactor 61 come into contact again, the adjustment switch SW2 is turned on, and the blade body 2 swings to the left or right.
When the contact plate 51 reaches a predetermined position, the adjustment switch SW2 is turned off, and the blade body 2 swings to the left by the amount of movement of the operating knob 6 and then stops.

(Effects of the Invention) As is clear from the above description, according to the present invention, the wind direction adjusting device is provided at both left and right ends in the width direction of the vehicle interior and near the center of the vehicle interior, and is pivotably supported to be swingable from side to side at least. In an air conditioning outlet that is equipped with a blade body and is configured to be adjustable so that ventilation is directed toward the occupants, at least one outlet on the outside on the driver's seat side and at least one outlet near the center of the passenger compartment are driven by a power source. A continuous left-right swing mechanism is attached to the blade body for adjusting the wind direction, and the swing mechanism enables the above-mentioned blade body to be driven at different swing cycles, while a manual left-right direction adjustment mechanism is attached to the remaining air outlet. Since the air conditioner outlet of the car is controlled by the air conditioner, when the airflow from the automatic movement is observed from the passenger's position, the amount of airflow increases and decreases with a certain period, and as a result of the airflow from two directions merging at different periods, The vector amount of the wind can be changed at random intervals, making it possible to blow air close to natural wind in artificial air conditioning.
