[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for a vehicle air conditioner.

[0002]

2. Description of the Related Art In general, as a control device for an air conditioner for a vehicle, an air outlet such as a foot opening, a vent opening, and a differential opening is selected to blow air to the feet, upper body, or windshield of an occupant. And control the air volume and temperature from the outlet.

[0003] Selection of each outlet, air volume adjustment, temperature adjustment,
The operation is performed by operating each of the air outlet operation unit, the air volume operation unit, and the temperature operation unit, and there is a unit using a dial-type operation unit as the operation unit. There is one shown in Japanese Patent No. 231956.

[0004] Three dial-type operation units are arranged side by side, and each operation unit is respectively connected to a control drive unit. By operating the dial-type operation unit, each air outlet is opened via the control drive unit. Selection and adjustment of air volume, temperature and the like.

[0005]

The air outlet operation unit, the air volume operation unit, and the temperature operation unit, which are dial type operation units, are integrally formed on a control panel rising from the base member, and each control drive unit is integrally formed on the base member. The control device is assembled and unitized.

[0006] For this reason, by assembling the base member to the instrument panel, the assembling is completed at once, and the assembling property is excellent. It is necessary to make a control device for each operation, and because the base member for assembling each operation unit cannot be made unnecessarily large, it is not expected to improve the design flexibility such as being restricted by the arrangement,
At present, modularization of the instrument panel and each control drive unit and operation unit is being promoted, but with the current means using a base member, modularization is not possible in terms of the design flexibility of each operation unit. There were problems such as leprosy.

Accordingly, an object of the present invention is to provide a control device for an air conditioner for a vehicle which solves the above-mentioned problems.

[0008]

In order to achieve the above object, according to the first aspect of the present invention, each control drive unit of the air conditioner is independently provided on the back surface of the instrument panel. On the other hand, a dial-type operation unit for directly operating each of the independent control driving units by rotating them is provided on the front surface of the instrument panel.

Thus, the instrument panel has
Since each control drive unit and dial-type operation unit can be assembled independently of each other, modularization is possible, and the layout area is expanded, and the space between each operation unit and the operation unit can be freely set. Be able to set. As a result, the degree of design freedom for arranging each operation unit is greatly improved.

According to a second aspect of the present invention, each control drive unit is provided with an operating mechanism for converting a rotary motion from a dial-type operation unit into a pulling motion of the control wire, and the control wire is connected to the control drive unit. Fixedly supported.

[0011] By rotating the operating section, the control wire can be easily and easily selected by controlling the pulling of the control wire, for example, the differential port, the foot port, etc., and the control wire can be reliably and stably operated. Operating state is obtained.

According to a third aspect of the present invention, a plurality of control driving units are fixedly set on the back surface of the instrument panel while the control wires are fixedly supported.

This makes it possible to use the same components for the control drive unit and the control wire,
It leads to cost reduction.

Further, the control wires can be stably supported and arranged without being affected by the layout of the control drive unit corresponding to each vehicle type.
