Description

Indoor air exhaust device of vehicle using air conditioner blower

The present invention relates to an indoor air exhaust device of a vehicle using an air conditioner blower, and in particular, a first damper for opening and closing between an evaporator and a blower fan is installed in the air conditioner blower unit, and the indoor air through the blower fan is formed on the cowl top panel. The present invention relates to an indoor air discharge device for a vehicle using an air conditioner blower provided with a second damper for controlling discharge to an outlet.

In general, the air conditioner of the vehicle performs a function to cool the air in the vehicle while circulating the indoor air. For this purpose, a heat exchanger such as an evaporator and a blower unit are used. However, if the air in the car is contaminated with cigarettes or dust, it is inconvenient to use it because the windows and the like must be discharged to discharge it indoors, and heat loss is also enormous when using air conditioners.

An object of the present invention is to enable the discharge of dirty air in a room forcibly outside the vehicle even when using an air conditioner.

To this end, the present invention uses a conventional air conditioner evaporator and a blower unit, adds a configuration for discharging indoor air to the outside, and utilizes an air conditioner blower unit to provide air in the vehicle without having to install additional expensive equipment. Discharge to the outside.

That is, the present invention provides a blower unit interlocking with an air conditioner operating damper, a first damper installed between an evaporator and a blower fan, a second damper for guiding indoor air through the blower unit to the outlet of the cowl top panel, and a second damper. It consists of a duct that blocks the engine room and the air through the damper to the outlet.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

Figure 1 is a schematic perspective view showing an installation state of the present invention, Figure 2 is an enlarged cross-sectional view of the main part of the present invention, the air conditioner outlet 5 of the blower unit 3 corresponding to the opening and closing damper 4 is installed, cowl top The outlet 31 and the blower unit 3 formed in the panel 32 are connected to each other by the duct 34, and the blower unit 3 and the duct 34 are opened and closed by the second damper. Of course, the duct 34 is isolated from the engine room 35. The second damper 20 is driven by the second actuator 23. 36 is a dashboard in the vehicle body.

FIG. 3 is a cross-sectional view taken along line AA of FIG. 2, wherein a first damper 10 driven by an actuator 11 is installed between the evaporator 1 and the blower unit 3, and a blower fan of the blower unit 3 is provided. Between the 2) and the duct 34, a second damper 20 driven by the actuator 23 is provided. Of course, the control panel panel 37 installed on the dashboard is required to set the button 38 for selecting the discharge of air. In addition, the button 38 should be wired so as to apply a power source for driving the actuators 11 and 23.

4 is an enlarged view showing an example of the second damper 20 of the present invention, the second damper 20 is an endless roll film 22 supported by a pair of rod 21 and the rod 21 The actuator 23 to rotate and the ventilation hole 24 is formed in the film 22 at regular intervals to perform a function of conducting or blocking air.

When the present invention constructed as described above is described, normally, the second damper 20 shown in FIG. 2 is closed, and the damper 4 is driven in a dotted line, and the evaporator 1 and the blower unit 3 are communicated with each other. 5) Through the circulation of the cool air to the room. In this state, when the indoor air is contaminated or there is a lot of dust, when the output button 38 shown in FIG. 3 is pressed, the second damper 20 opens and the air in the room through the blower fan 2 exits through the duct 34. 31 is discharged as an arrow. In this case, the second damper 20 has a rectangular vent hole 24 in the roll film 22 as shown in FIGS. 4 and 5, and when the vent hole 24 is located at the center between the rods 21 as shown in FIG. 5A. To communicate with each other to release air. However, when the vent hole 24 is placed in the rod 21 as shown in FIG. 5B, the vent hole is blocked by the roll film 22, thereby controlling the discharge of air.

As described above, the present invention adds two separate dampers around the existing blower unit and forms an outlet in the cowl top panel to open the damper and discharge the indoor dirty air through the blower fan. Therefore, the polluted air in the room is easily discharged, and the existing blower unit is utilized, so the cost of installing the configuration is low.
