Description

TECHNICAL FIELD [0001] The present invention relates to an air conditioning system for an automobile,

The present invention relates to an air conditioner for a vehicle, and more particularly, to an air conditioner for an automobile, and more particularly to an air conditioner for a vehicle, which is configured to enable or disable the automatic control functions as needed, To a vehicle air conditioner.

BACKGROUND OF THE INVENTION [0002] Recent automotive air conditioners have various "automatic control functions" for maintaining the temperature of a vehicle interior in an optimum state and improving user's convenience.

As an example, there are a self-diagnosis function, an internal / external automatic switching function, a blower reference rotation speed automatic adjustment function, a defogging function, a setting value initialization function, It has automatic control function for indoor and outdoor according to CO ₂ concentration.

The self-diagnosis function determines whether various units of the air conditioner, for example, various actuators and sensors, are malfunctioning, and then displays the determined result on the display unit of the controller. Accordingly, the user is informed of the failure of the air conditioner.

The automatic internal / external switching function is a function to automatically switch the outside air and the outside air introduced into the car according to the state of the outside air and the inside air, so that the optimum air can be introduced into the inside of the car.

For example, when the air in the vehicle interior is contaminated, fresh air from the outside is introduced by switching from the inside air mode to the outside air mode. Conversely, when the outside air is contaminated, the outside air mode is switched from the outside air mode to the outside air mode to block the introduction of outside air. Further, when the temperature of the outside air is too low or high, the outdoor mode is switched from the outdoor mode to the indoor mode to shut off the introduction of outside air at a high or low temperature. Therefore, the air in the car is always maintained in a comfortable state.

The blower reference rotation speed automatic adjustment function controls the reference rotation speed of the blower by controlling the reference rotation speed of the blower with the FAST so as to increase the basic blowing intensity of the air discharged into the vehicle interior, Controls the reference rotation speed to about SOFT so as to lower the basic air blowing intensity of the air discharged into the vehicle interior.

When the fogging occurs in the window glass of the car interior, the defogging function is switched to the "defogging mode", and the air discharge direction is controlled to the window glass side and the air conditioner is turned on. Allows to remove the fogging of the window glass by blowing. Therefore, it helps the driver to drive safely.

The setting value initialization function initializes all the setting values of the air conditioner so that all the control functions of the air conditioner can be restored to the initial setting values. Therefore, it is useful for restoring operating error or setting value of the air conditioner. This improves the convenience of the user.

The indoor / outdoor setting temperature unit (° C / ° F) change function allows the temperature and the set temperature unit of the inside and outside of the vehicle displayed on the display unit to be changed to either Celsius (° C) or Fahrenheit (° F).

The automatic control of the inside and outside according to the CO ₂ concentration in the car enables automatic control of the inside and outside air according to the CO ₂ concentration in the car interior. As a result, the sleeping operation of the driver is prevented, and the interior of the vehicle is always kept comfortable.

However, such a conventional air conditioner has a disadvantage in that the automatic control functions are automatically controlled irrespective of the will of the user, so that they are operated in spite of the fact that the user does not want to. The disadvantage is that the user feels a lot of discomfort It is true.

For example, even if the user forcibly adjusts the ventilation mode due to the user's dislike of inflow of outside air, the defogging function or the internal / external automatic switching function automatically operates when the window glass is fogged or the air in the interior of the vehicle is detected as contaminated And automatically switches to the outside air mode. Therefore, even though the user selects bet, the outside air is introduced into the passenger compartment. As a result, the user feels a lot of uncomfortable feeling.

On the other hand, in consideration of this, there are installed devices for "activating and deactivating" automatic control functions.

This apparatus is configured such that when the specific buttons of the controller are operated in combination, the corresponding automatic control function is activated or deactivated. Therefore, the user can disable the automatic control function that he does not want.

However, such a conventional activating and deactivating device has a disadvantage in that it is constituted by different button combinations for each automatic control function. When the automatic control functions are "activated or deactivated" due to such a disadvantage, There is a problem that the buttons must be operated.

And because of these problems, most users are reluctant to use them. Moreover, since the automatic control function requires one to memorize the combination of "active and inactive" buttons, it is in a great difficult situation.

SUMMARY OF THE INVENTION The present invention has been made to overcome the above-mentioned problems, and an object of the present invention is to provide a vehicle air conditioner capable of activating or deactivating an automatic control function as needed.
