Hereinafter, the operation of the ventilation device configured as described above will be described with reference to FIGS. 6 to 12.

 Figure 10 is a state diagram showing the air flow path when the ventilator employing a preferred embodiment of the present invention when operating in the ventilation mode, Figure 11 is an air flow path when the ventilator employing a preferred embodiment of the present invention is operated in a clean mode Figure 12 is a state diagram, Figure 12 is a state diagram showing the air flow path when the ventilator employing a preferred embodiment of the present invention operating in the ventilation, clean mode.

First, referring to FIG. 10, when the air flow path of the ventilation device is operated in the ventilation mode, the indoor air guide damper 542 shields the first hole 512, and the outside air guide damper 544 includes a third air flow path. In the state in which the hole 532 is opened, power is applied to the air supply motor 220 and the exhaust motor 320 to generate rotational power.

In this case, the air supply fan 240 and the exhaust fan 340 generate air flow, so that indoor air and outside air flow into the ventilation device.

Referring to the arrow of Figure 10, the suction air is generated in the indoor suction port 132, the indoor air is introduced, the suction force is generated by the suction force transmitted from the exhaust fan 340 to the outdoor suction port 124.

In addition, the indoor air introduced through the indoor suction port 132 is discharged downward through the air supply assembly 200 and then passes through the communication hole 152.

At this time, since the first hole 512 is shielded by the indoor air guide damper 542 and the second hole 522 is opened, the indoor air exiting the communication hole 152 is guided to the outside and discharged. .

At the same time, the outside air introduced into the ventilation device through the outdoor suction port 124 is guided along the outside air guide plate 530 and moved to the left side, and the first hole 512 is moved by the indoor air guide damper 542. Since it is shielded, it moves upward and passes through the filter 420 (see FIG. 6 for a link and gear state).

Air filtered while passing through the filter 420 is sucked into the exhaust assembly 300, and then the flow direction is guided upward by the exhaust housing 360 to the indoor space through the indoor outlet 134. Discharged.

Therefore, the muddy indoor air is discharged to the outside through the above process, and the fresh air is supplied to the room in a purified state to perform the ventilation mode.

Next, referring to FIG. 11, when the ventilator is operated in the clean mode, the air flow path is examined. The indoor air guide damper 542 opens the first hole 512 by shielding the second hole 522. The air guide damper 544 is shielded from the third hole 532. (See FIG. 7 for a link and a gear state.)

In this state, when the air supply motor 220 and the exhaust motor 320 operate to generate rotational power, the air supply fan 240 inhales indoor air by transferring suction power to the indoor suction port 132. Discharged downward through the housing 260.

The air discharged from the air supply housing 260 passes through the communication hole 152 and then moves to the filter 420 through the first hole 512.

The indoor air moved to the filter 420 is purged by removing foreign substances while passing through the filter 420, and then quickly moves in the direction in which the exhaust assembly 300 is located by the suction force generated by the exhaust assembly 300. Will flow.

Thereafter, the clean indoor air passing through the exhaust assembly 300 is supplied to the room through the indoor discharge port 134.

Therefore, by repeating the above process, the muddy indoor air is purified by the filter 420 and supplied to the indoor space, thereby changing the indoor air to a clean state.

Hereinafter, referring to FIG. 12, an air flow path when the ventilation device is operated in a ventilation / clean mode will be described.

First, when the damper assembly 500 is operated in the ventilation / clean mode, both the first hole 512, the second hole 522, and the third hole 532 are opened. 8)

That is, the damper motor 550 generates a rotational power in the indoor air guide damper 542 and the air guide damper 544 as shown in FIG. 11 to the indoor air guide damper 542 and the outside air guide damper 544. When the rotational power is provided, the indoor air guide damper 542 and the outdoor air guide damper 544 rotate in a direction close to each other to open the second hole 522 and the third hole 532.

At this time, the indoor air guide damper 542 and the outdoor air guide damper 544 are rotated only by a predetermined angle as shown in FIG. 12 to maintain the stopped state. The holes 532 are all kept open.

Then, when the exhaust fan 340 and the air supply fan 240 force the air flow by the rotational power generated by the air supply motor 220 and the exhaust motor 320, indoor air is introduced through the indoor suction port 132. Outdoor air is introduced into the outdoor suction port 124.

In addition, the indoor air introduced into the indoor suction port 132 exits the barrier 150 through the communication hole 152, and is then divided by the indoor air circulation guide plate 510.

That is, the air moving in the lower left direction based on the indoor air circulation guide plate 510 is discharged to the outside through the second hole 522 and the outdoor discharge port 122, and the indoor air circulation guide plate 510 The air moving downward from the top is guided to the right along the inclined surface of the indoor air circulation guide plate 510 to pass through the first hole 512.

On the other hand, the outside air introduced through the outdoor suction port 124 passes through the outside air guide plate 530 through the third hole 532 and at the same time merges with the indoor air passing through the first hole 512. And moves to the filter 420.

The indoor air and the outdoor air moved to the filter 420 are purified and then forced upward by the exhaust assembly 300 and then supplied to the indoor space through the indoor outlet 134.

Therefore, some of the muddy indoor air is discharged to the outside through the above process, the rest is purified and supplied to the indoor space, and at the same time fresh air is supplied to the indoor space after the foreign matter is removed by the filter 420 to ventilate Clean mode is performed.

When the temperature difference between the indoor and the outdoor air is large during the above-described ventilation mode and the ventilation / cleaning mode, the heat exchange efficiency is lowered by operating the heater 126 to heat the outside air introduced through the outdoor suction port 124. You can stop it.

In more detail, when the heater is operated indoors in the winter season and the indoor air is warmer than the outdoors, when the outdoor air is supplied to the indoor space without the heater 126 operated, the warmed air may be cold, so as to prevent the above. It is apparent that the heater 126 may be operated.

Hereinafter, a process for cleaning the filter will be described with reference to FIGS. 9 and 13.

Figure 13 is a partial longitudinal cross-sectional view showing a state that the filter service panel is opened in the case of the ventilation apparatus according to the present invention.

First, in order to separate the filter 420 from the inside of the ventilator, the coupling member F is picked up by hand and then rotated to release the fastening force from the nut 147.

At this time, the filter service panel 148 is rotatable in a counterclockwise direction with respect to the bent portion 143 'and falls due to the interference between the bent portion 143' and the drop preventing portion 149 as shown in FIG. Will not be.

In this state, when the separation prevention mechanism 426 is rotated to cancel the interference with the filter 420, the filter 420 is slid out of the filter bracket 440 to be withdrawn.

When the filter 420 is withdrawn from the ventilator, the filter may be washed or replaced with a new filter 420. The process of coupling the filter service panel 148 to the heater service panel 146 may be performed in the reverse order of the above-described separation process. Therefore, it will be omitted.

The scope of the present invention is not limited to the above-exemplified embodiments, and many other modifications based on the present invention will be possible to those skilled in the art within the above technical scope.

For example, in the embodiment of the present invention, the drop prevention portion is formed at the end of the filter service panel so as to be rotatable with respect to the fan motor service panel. However, if necessary, the filter service panel and the fan motor service panel are connected by hinges or hinges. Of course, it can be configured to be rotatable as well as to prevent the fall (of course see Figure 14 and Figure 15).

According to the ventilation device as described above, there is provided a plurality of service panels that can be selectively removed when the service of the filter or control box provided in the case is required.

Therefore, by selectively separating the service panel corresponding to the parts to be repaired can be opened inside the ventilator has the advantage that the serviceability is improved.

In addition, the service panel is configured not to fall from the case when opening the service panel.

Therefore, it is preferable because the risk of safety accidents is significantly lowered.
