It is comprised so that the outside air discharge fan drive circuit part 280 and the inside air discharge fan drive circuit part 290 may be connected.

In addition, a first communication port 250 is connected to the bidirectional input / output terminal of the sub-central processing unit 210, and power supplied from the outside is supplied to the first motor driving circuit unit 220 via the power supply unit 260. At the same time, the power of the power supply unit 260 is rectified and charged to the charging unit 270, and the power of the charging unit 270 is applied to the first communication port 250.

Meanwhile, the first communication port 250 of the control circuit unit 200 is configured to be connected to the second communication port 350, which is a bidirectional input / output port of the main central processing unit 310 of the room control circuit unit 300.

The room control circuit 300 is installed on the wall of the room can be directly manipulated by the user or remotely controlled by the remote control transmission circuit 400, the CO ₂ detection sensor in the input port of the main central processing unit 310 ( 320 is connected, and the LCD drive circuit 330 is connected to the output port of the main central processing unit 310.

Operation of the ventilation unit for controlling the supply and discharge amount having such a configuration is first turned on the power switch (not shown), the power is applied to the power supply unit 260 of the control circuit unit 200 and is charged through the charging unit 270 at the same time. .

In this state, the indoor state is detected through the C0 ₂ sensor 320 connected to the room control circuit unit 300, and the detected value is applied to the main central control unit 310, and the main central control unit 310 is These values are compared with the data codes (setting values) stored in the memory to output the corresponding output signals through the second communication port 350, which is output to the first communication port 250 of the control circuit unit 200. Via the sub central processing unit 210 is applied.

As it is discharged to the indoor and outdoor, it is possible to provide a comfortable indoor space by the ventilation is smooth.

When the air temperature discharged into the room during the winter is too low, if only the bypass damper 172 is opened while the discharge damper 150 is closed, the foreign matter that has passed through the filter 111 which is in contact with the heat exchange member 110 is released. As the air to be removed is discharged to the room through the bypass port 170 and the total heat exchange member 110 without being discharged to the outside, it is possible to reduce the heat loss.

During this process, the user presses a specific key of the remote control transmitter circuit 400, that is, the remote controller, and at the same time, a data code corresponding to the key is modulated to a carrier frequency through a modulator and transmitted as an infrared signal through an IR-LED driving circuit. While the infrared signal is received from the remote control receiving circuit unit 340 installed in the room control circuit unit 300, a signal corresponding to the data code corresponding to the received value is transmitted to the sub center of the control circuit unit 200 through the second communication port 350.

When the open damper 170 is opened at 60 °, 75 °, and 90 °, the opening amount of the bypass damper 170 may be operated at 0 °, 60 °, 30 °, 25 °, and 0 °.

In addition, the servo motor is used as a way to easily adjust the opening amount of the discharge damper 150, the inlet damper 160 and the bypass damper 170, but not shown installed on the circuit board other than the servo motor It is to be operated by using a separate limit switch, which may be done by the above-described remote control transmission circuit.

In other words, as shown in FIG. 5, the first and second motors of the discharge damper and the inlet damper formed in the air outlet and the external air inlet of the present invention are wirelessly controlled by the above-described remote control transmitter and room control circuit. In more detail, the first and second motors are substantially formed as actuators.

As shown in FIG. 6, the drive motor is for DC 12V and has a simple shape of low noise and high output by using a reduction gear using a worm gear, and is connected to the blade by a coupling between the drive motor and the damper shaft to provide power. It serves to convey.

At this time, the power unit is converted to AC 12V to DC 12V to enable the arbitrary adjustment of the angle by the smooth control remote control, the control unit is controlled by the operation of the room control circuit unit various angles (0, 30, 45, 60, 75, 90 °) blade is formed to allow adjustment. This advances the role of adjusting the angle by the conventional manual method, which leads to more smooth and various exhaust efficiency.

In addition, as shown in Figures 7 to 8, the present invention functions to turn off (close) the discharge damper and the inlet damper (due to fire and other emergencies) during a power failure by using a charging electronic circuit. It serves to act as a fire damper.

On the other hand, the limit switch is located on the back of the PCB, and each switch maintains 90 ° (the angle between the damper closing and the full opening) and serves to cut off the power by the operation of the arm connected to the coupling.

At this time, the coupling connects the drive motor shaft and the damper shaft so that the rotational force of the drive motor is transmitted to the blade to maintain the open and closed state of the discharge damper or inlet damper, which is the arm connected to the body of the coupling limit switch To activate the function.

In addition, the manual angle control device is a device for manually adjusting the arbitrary angle using the charging electronic circuit and the product for moving the existing limit switch (adjust the arbitrary angle by using a control device that can move the limit switch Compared to the hassle of using a manual adjustment device to adjust the angle, the electronic parts (volume) can be used to easily adjust the angle.

That is, it can be adjusted using a screwdriver or a simple tool, and can be easily adjusted by hand by adjusting the length of the arm.

On the other hand, the body corresponding to the main body of the discharge damper and the inlet damper uses a cold rolled steel sheet and is finished with powder coating.

At this time, the blade uses a galvanized steel sheet bonded with a silicon gasket for airtightness, and can be completely closed by the silicon gasket, thereby preventing outside air and rainwater inflow and blocking noise to provide a more comfortable living environment.

The shaft uses a round bar and is coupled to the blade by bolts and is connected to the drive motor by the coupling to transfer the power of the drive motor to the blade to maintain the closed and open state.
