Description

Controllers for car air conditioners

The present invention relates to a control device for a vehicle air conditioner, and more particularly, to a control device for a vehicle air conditioner to keep the air in the vehicle clean by discharging the air in the vehicle to the outside.

In general, a vehicle is provided with an air conditioner (hereinafter referred to as an air conditioner), which is a device for increasing comfort and comfort of occupants in a vehicle while driving the vehicle, and promoting safe driving. It aims to give passengers a pleasant feeling by maintaining a moderate and air environment.

The air conditioning system is a heater and air conditioner, which is an air conditioning and heating device for maintaining a proper temperature in a vehicle, a ventilation mode (external mode) for sucking fresh air from the outside of the vehicle and replacing it with air in the vehicle, and an operation of a cooling and heating device. In order to increase the efficiency of the vehicle, there is a betting mode in which the air inside the car is not circulated to the outside, that is, the betting mode in which the air in the car continuously circulates, and the outside mode is the ventilation mode, and the betting mode is the recirculation mode. Also called mode).

And, as shown in Figure 1, briefly described the operation by the air conditioning apparatus as follows.

When the air conditioner is operated, the outside air is sucked by the blower 1 and flows along the duct 2. The air changes through the heater unit 3 or the evaporator unit 4 and is positioned in the vehicle. The ventilator 5 is discharged into the vehicle.

The blower 1 consists of a blower fan 11 and a blower motor 12 which drives the blower fan 11.

The ventilator 5 is installed at the front foot, the rear foot, the center of the crash pad, and at the left and right sides, respectively, and also includes a defroster ventilator for removing frost frozen in the glass.

On the other hand, substances that are harmful to the human body such as dust (referring to solid particles formed by natural operations such as wind or artificial operations such as crushing) are contained in the air discharged into the vehicle by driving the vehicle in an outdoor mode or by operating an air conditioning unit. In particular, when the vehicle is waiting for a signal or the traffic is heavy, when the vehicle is stopped and restarted, a large amount of exhaust gas, dust, etc. emitted from the vehicle in front is introduced.

In this case, the outside air is selected to circulate the outside air. However, the air flow in the outside air mode is circulated by the air being pushed to the outside as the density of the air inside the car increases due to the inflow of outside air, and thus the air polluted in the car more effectively because the air flow is not smooth. Air is vented inside the car by opening the windows so that the car can be discharged.

However, in the conventional vehicle, when the air in the car is kept clean by opening the window and introducing the outside air, there are the following problems.

First, the high noise of the vehicle at the high speed of driving because the dwelling and comfort of the vehicle is reduced.

Secondly, there is a problem in that the air in the car can not be kept clean because the air is not circulated smoothly during the stop.

Third, in rainy weather, rainwater was introduced into the vehicle, causing another problem of contamination of the seat, floor, as well as the clothes of the occupants.

In addition, in the case of installing an air purifier, a dust collector, etc. in the vehicle in addition to the above-described method, there is a problem in that an economic burden of the consumer is generated because of the cost of a separate purchase.

The present invention has been devised to solve the problems described above, so that the polluted air in the car can be discharged without opening the window so that outside noise does not flow into the interior to improve the habitability and comfort of the vehicle. It is an object of the present invention to provide a control device for an automotive air conditioner.

In addition, while the vehicle is stopped, the polluted air in the vehicle is discharged to the outside to maintain the cleanness of the air in the vehicle.

In addition, it is intended to prevent contamination of the vehicle by rainwater so that rainwater does not flow when the air in the vehicle is discharged.

In addition, another object of the present invention is to reduce the cost by eliminating the pollution in the vehicle without a separate device.
