Description

Air Conditioning Apparatus for Vehicles

The present invention relates to an air conditioner for an automobile, and more particularly, an air conditioning passage, an air conditioning passage, which is a case for guiding and distributing a fluid flow caused by a plurality of operating members and operating members for cooling and heating in a vehicle interior. The present invention relates to providing a configuration for minimizing the overall size and efficiently performing thermal efficiency and control of fluid flow by improving the configuration of the door plate intermittently controlling the flow of fluid flow.

The air conditioner in a typical automobile is provided with an airflow passage, which is an air-cooled casing which is an injection combination of plastics, which is a component mounted on a chassis of a vehicle to perform cooling and heating of a vehicle interior.

In addition, as an operating member for heating and cooling the flow fluid inside the air-conditioning case as the air flow passage, a motor, a fan, an evaporator, a heater, and a fluid controlled by each operating member are distributed and intermittently controlled. It is comprised by providing the door plate which is a plurality of plate-shaped members normally supported as a member for doing so.

In the above-described conventional configuration, the evaporator in which a tube is disposed between a pair of opposing fluid tanks in a granular fluid flow path is inevitably configured as a substantially flat size to ensure minimum cooling efficiency.

In order to mount such an evaporator in an air conditioning case composed of a plastic injection molded body, a separate evaporator case is formed and inserted into the entire air conditioning case to be assembled and assembled, thereby increasing the number of assembly operations and increasing the overall size.

The above problems are particularly limited in the case of the chassis, which is a mounting space, and in the case of small and light vehicles, which considerably limit the design of the air conditioner. However, when the size of the evaporator is reduced, It is impossible to adopt due to the drastic reduction of efficiency.

In addition, the door plate, which is a plate-like member, is hingedly supported on one side in the air-conditioning case in the past, and is axially supported on each intermittent portion of the air-conditioning case, and then the door plate is driven by a vacuum actuator, a motor, or the like. do.

Accordingly, the space for mounting the vacuum actuator, the space for connecting the vacuum actuator and the door plate, and the space for mounting the vacuum actuator are increased, and the interference between the operating members is increased, which causes failure and noise.

In addition, efforts have been made in the past to drive a plurality of door plates with a minimum driving power and to minimize a mounting space, and this attempt simultaneously drives a plurality of door plates in an air conditioning case as operating members such as one operating actuator. By doing so, the overall structure can be simplified and the cost can be reduced.

As an example of a drive configuration of a door plate that has been conventionally drawn, the door is formed by rotating mechanically as a concave groove in which a driving lever is fixed to an end of a plurality of door plates and a concave groove in which an operation path is accommodated so as to receive pins arranged directly on the driving lever, respectively. There is a drive plate for controlling the drive mode of the plate,

Another aspect is that the drive lever fixed to the hinge shaft end of the plurality of door plates connected by a plurality of segmented link configuration, the interlocking, opening and closing control.

However, all of the above configurations are optimized for driving a plate-shaped door plate, and there is an effect of reducing power and reducing the number of constituent members, but the effect of reducing the size of the entire air conditioning case or lowering the operation noise is insignificant.

In particular, in the case of the door plate, the operation noise is likely to be easily introduced into the room during the connection with the connection portion with the air conditioning case during operation, and has a problem that is not suitable for light compact cars.

In addition, by constructing and mounting a separate evaporator case, there have been economic closures requiring an increase in the number of assembly operations and an unnecessary assembly member.
