따라서 본 발명에 따른 전열교환기가 환기운전을 수행할 경우에는 제 1 개폐댐퍼(41) 및 제 2 개폐댐퍼(42)에 의해 연통공(13)이 폐쇄되어 있는 상태를 유지하 다가, 필터(30)가 일정 이상 오염되어 필터청소운전을 수행할 경우에는 두 댐퍼 구동모터(41a, 42a)에 전원이 인가되어 도 2에 도시되어 있는 바와 같이 제 1 개폐댐퍼(41) 및 제 2 개폐댐퍼(42)가 회동하여 실내 배기구(11b) 및 실내 흡기구(12a)는 폐쇄하고 흡기유로(11)와 배기유로(12)는 연통공(13)을 통해 서로 연통되도록 하며 그와 동시에 흡기팬(11c) 및 배기팬(12c)이 역방향으로 회전하여 공기가 역방향으로 회전하게 하면, 실외 공기는 실외 배기구(12b)를 통해 배기유로(12)로 유입된 후, 개방되어 있는 연통공(13)을 통해 흡기유로(11)로 전달되고, 계속해서 실외 흡기구(11a)를 통해 배출되면서 실외 흡기구(11a)에 설치되어 있는 필터(30)를 역방향으로 관통하며 필터(30)에 쌓인 먼지가 실외 공간으로 제거하게 된다. Therefore, when the total heat exchanger according to the present invention performs the ventilation operation, the communication hole 13 is kept closed by the first opening / closing damper 41 and the second opening / closing damper 42, and the filter 30 Is contaminated more than a predetermined time and the filter cleaning operation is performed, power is applied to the two damper driving motors 41a and 42a so that the first opening / closing damper 41 and the second opening / closing damper 42 are shown in FIG. 2. And the indoor exhaust port 11b and the indoor intake port 12a are closed so that the intake flow passage 11 and the exhaust flow passage 12 communicate with each other through the communication hole 13, and at the same time, the intake fan 11c and the exhaust fan When 12c rotates in the reverse direction and the air rotates in the reverse direction, outdoor air flows into the exhaust passage 12 through the outdoor exhaust port 12b and then the intake passage 11 through the open communication hole 13. ) And is continuously discharged through the outdoor intake port (11a) while the outdoor intake port (11a) The filter 30 is installed in the reverse direction and the dust accumulated in the filter 30 is removed to the outdoor space.

이상에서 상세히 설명한 바와 같이, 본 발명에 따른 전열교환기는 공기가 역방향으로 흐르며 필터가 설치되어 있는 실외 흡기구를 통해 배출되게 하는 필터청소유닛이 구비되어 있으므로, 필터에 쌓여 있는 이물질이 필터를 역방향으로 관통하여 흐르는 공기에 의해 실외 공간으로 배출되어 제거되므로 필터의 청소가 간단하게 이루어지게 되는 작용효과가 있다.As described in detail above, the electrothermal heat exchanger according to the present invention is provided with a filter cleaning unit which allows air to flow in the reverse direction and is discharged through the outdoor intake port where the filter is installed, so that foreign matters accumulated in the filter penetrate the filter in the reverse direction. It is discharged to the outdoor space by the flowing air to remove the filter has the effect of making it easy to clean the filter.
