Abstract

The present invention relates to a ventilation apparatus for automatically ventilating the in-vehicle ventilation of the vehicle according to the pollution degree of the vehicle air, the pollution detector detects the pollution degree of the vehicle air and automatically operates the fan to operate the pollution degree in the vehicle environment In order to judge objectively rather than by intuition, the inside of the car is always comfortable and the safe operation can be performed by excluding the driver's direct operation.

The present invention relates to a ventilator for automatically ventilating the in-vehicle ventilation of the car according to the pollution degree of the in-vehicle air, in particular for the automatic ventilation of the car to enable the ventilation of the air in the car by the sensor without the operation of the driver Relates to a device.

In general, the fan mounted on the car is made by the driver's own operation regardless of the pollution level in the car. When the driver feels frustrated while driving or the air is muddy, the fan is turned on and the fan is turned on. Has been used to exhaust and inhale external air.

Therefore, in the case of a vehicle in which a large number of unspecified passengers, such as buses, are carried by the driver, the comfort of the in-vehicle air is entirely made by the driver, so the driver in front of the vehicle does not recognize the environment in the rear of the vehicle and is driven by polluted air. It was difficult to create a comfortable environment in the car, such as motion sickness, and the driver was operating a ventilator to ventilate the inside of the car, causing a lot of problems in driving safety due to careless driving.

The present invention has been created to solve the above conventional problems,

The pollution detector detects the pollution level of the air inside the vehicle and automatically starts the ventilation fan so that the pollution level of the vehicle environment can be objectively judged by the driver's intuition, so that the inside of the car is always comfortable and safe operation is performed by excluding the driver's direct operation. It is an object of the present invention to provide an automatic ventilator capable of doing so.

Hereinafter, described in detail by the accompanying drawings of the present invention.

The accompanying drawings are circuit diagrams of an automatic ventilation device according to the present invention.

A regulator 2 to which a power source Bat is applied by the selection switch 1; A pollution detector 3 for detecting an air pollution level in the vehicle; A comparator (4) for receiving the signals from the regulator (2) and the pollution detector (3) to compare the pollution degree of the vehicle environment; A chattering prevention and delay circuit (5) in which the comparator (4) controls a malfunction caused by a foreign matter; A display unit 14 which displays when the in-vehicle air is contaminated; When the in-vehicle air is contaminated, a signal is received from the chattering prevention and delay circuit 5 so that the switches 12 and 13 are turned on and off, so that the motors 10 and 11 operate to discharge the in-vehicle air. 8) and a ventilator 6 composed of an inhaler 9 for sucking outside air; It is composed of a circuit breaker (7) for receiving the signal of the chattering prevention and delay circuit (5) to block the external air in accordance with the operation of the fan (6).

Looking at the operation, effects of the present invention configured as described above,

The driver operates the selector switch 1 at the beginning of the operation to select whether to automatically / manually or stop the in-vehicle ventilation, and when the driver operates, the pollution detector 3 and the The operation of the ventilator 6 is stopped, and if the contact point c for manually selecting the selector switch 1, the ejector 8 of the ventilator 6 and the switches 12 and 13 of the inhaler 9 are turned on. The operation of the motors 10 and 11 is made, and the breaker 7 is opened to circulate the outside air and the in-vehicle air, thereby purifying the in-vehicle air until the driver selects the selector switch 1 in a stopped state. will be.

Then, when the driver selects the selection switch 1 as the contact point (a) which automatically selects the power supply to the regulator 2, the comparator 4, the delay circuit 5 and the pollution detector 3, the pollution detector When (3) measures the pollution level of the in-vehicle air and applies it to the comparator (4), the comparator (4) compares the signal of the contamination detector (3) in a constant voltage state by the regulator (2) and the in-vehicle air is contaminated When the signal is input to the fan 6, the pollution detector 3 is prevented from operating when the contamination level of the in-vehicle air is misjudged by the foreign matter. If the malfunction of the pollution degree is not wrong, the power supply is applied to the display unit 14 and the fan 6 so that the display unit 14 displays the pollution of the environment inside the vehicle and the switch 12 of the fan 6 ( 13) will be turned on.

Therefore, the ejector 8 and the inhaler 9 constituting the ventilator 6 are operated in accordance with the driving of the motor 10, 11 and the breaker 7 at this time is opened for smooth ventilation of the in-vehicle air. The internal air is purified to circulate the external air and the internal air is purified to output a signal from the contamination detector 3, so that the switches 12 and 13 of the fan 6 are turned off in the comparator 4 and the breaker ( 7) It closes the purified air from the outside air.

As described above, according to the present invention, even when the driver does not directly operate the fan, the fan can be operated by a pollution detector that detects the pollution level of the air in the car, thereby maintaining a comfortable in-vehicle environment. It is an invention that can be planned.
