An air conditioner for a motor vehicle comprising a blower switch for establishing / powering a power supply circuit such that is driven, the apparatus comprising: adding a reverse rotation mode (R) to the blower switch (6); When the blower switch is selected as the reverse rotation mode, the blower motor 5 is reversely driven to blow air to the outside of the vehicle.

Description

Car air conditioner

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner of a motor vehicle, and more particularly, to an air conditioner having ventilation means for discharging air in a cabin, in particular, cigarette smoke in winter, to the outside.

As is well known, since the air inside the cabin is contaminated by the breathing of the occupant, inflow of foreign objects, dust, cigarette smoke, etc., it is necessary to draw fresh air (outside air) outside the cabin and replace it with the air inside the car. .

To this end, a vehicle is usually provided with a ventilator called an air conditioner as a device that allows the apparatus to flow into the room even when the window of the door is closed.

Ventilation devices are divided into natural ventilation and forced ventilation. Natural ventilation refers to a method of drawing outside air into the room by using wind pressure generated by a vehicle driving. The inlet for drawing air is installed at the place where the static pressure is applied, and the outlet for discharging the indoor air is installed at the place generating the negative pressure.

In addition, the forced ventilation method refers to forcibly introducing outside air by using an electric fan, and even in this case, the inlet and the outlet opening the outside air are arranged in the same manner as the natural ventilation method.

However, in the conventional ventilation apparatus, there is only a means for allowing outside air to flow into the cabin, and there is no means for discharging the polluted air inside, especially cigarette smoke harmful to the human body, to the outside.

Therefore, conventionally, by simply opening and closing the window glass of the door, the indoor air is discharged.

However, the opening and closing of the window glass as described above has a problem in that outside air at low temperature flows in winter and hot air flows in summer. In addition, there is a problem that a large amount of dust and foreign matter is introduced with the outside air.

As proposed in order to solve the problems of the prior art, the present invention does not need to open and close the window glass, so that the contaminated air in the room is discharged to the outside conveniently, so that a comfortable indoor environment can be created To provide an air conditioner of a vehicle equipped with a ventilation device.

Explanation of symbols on the main parts of the drawings

4 blower, 5 blower motor, 6 blower switch

As a means for realizing the above object, the present invention allows the blower of the forced circulation air conditioner to be driven in the opposite direction, so that the polluted air in the cabin can be forced to the outside.

That is, a blower forcing the outside air to be supplied to the inside of the vehicle through a heating and cooling device, a plurality of vents installed at arbitrary positions in the vehicle as the passage of the outside air, and a power supply circuit for driving the blower. The air conditioner of an automobile comprising a blower switch, wherein the blower is reverse driven to blow air to the outside of the cabin when the blower switch is selected as the reverse rotation mode.

To realize this, the blower is driven by a forward / reverse motor.

According to this configuration, the blower discharges the contaminated air in the vehicle, in particular, the cigarette smoke, to the outside of the vehicle, thereby realizing a comfortable environment in the room.

EMBODIMENT OF THE INVENTION Hereinafter, preferred embodiment for implementing this invention is demonstrated in detail based on an accompanying drawing.

EXAMPLE

1 is an overall configuration diagram showing an air conditioner of a vehicle according to the present embodiment.

In the drawings, reference numeral 1 denotes a grill installed on the instrument panel of the vehicle body, and 2 denotes a vent that is an inflow passage of outside air.

The vent 2 connected to the front of the vehicle body in the instrument panel is connected to the blower eva unit 3. The blower eva unit 3 is comprised with the air-conditioning apparatus which is not shown in figure, and the blower 4. As shown in FIG.

Here, the motor 5 of the blower 4 is driven by the power of the battery (B ⁺ ), it is made of a structure in which the blower switch 6 is connected between.

Therefore, when the driver artificially operates the blower switch 6 to select the blowing 1, 2, 3, or 4 modes, the blower motor 5 is operated accordingly, and the fresh air from outside is brought into the vehicle interior through the air conditioner. Supplied.

Here, the air conditioner according to the present embodiment is configured to allow the blower to be driven in the opposite direction, so that the polluted air in the cabin can be forced out.

In order to realize this, the blower switch 6 of this embodiment is established by newly establishing the reverse rotation mode R. As shown in FIG. In addition, when the blower switch 6 is selected as the reverse rotation mode (R), in order to receive the power supplied so that the blower 4 is rotated in the opposite direction, the motor 5 of the present embodiment is a forward / reverse rotation motor Is made of.

According to the above-described configuration of the present embodiment, the blower 4 operates the blower switch 6 in the reverse rotation mode when the blower 4 smokes in a state in which the window glass of the door is closed in winter, particularly in winter. As it is selected as R), it is driven back, forcing the polluted air in the cabin to be forced out of the cabin.

Through the embodiments described above, it can be seen that the air conditioner of the vehicle according to the present invention substantially solves the problems of the prior art.

That is, according to the present invention, by forcibly discharging the contaminated air in the vehicle cabin, the effect of realizing a comfortable indoor environment is obtained.

On the other hand, the present invention is not limited to the above-described specific preferred embodiment, and any person having ordinary skill in the art to which the invention belongs without departing from the gist of the invention claimed in the claims, various modifications Would be possible.

Claims (1)
