The design effect is enhanced.

また、室内側排気口１４と室内側給気口１５は同一面ではなく、異なる面に設けられることにより、排気流と給気流間のショートサーキットも無くなり効率良く換気できる。   Further, the indoor side exhaust port 14 and the indoor side air supply port 15 are not provided on the same surface but on different surfaces, so that a short circuit between the exhaust air flow and the air supply air flow is eliminated and ventilation can be performed efficiently.

また、前面パネル１６は、本体１３側に設けた仕切板２３および保持リブ２５により保持されることにより、厚みを薄く形成でき前面パネル１６の重量が軽くなり前面パネル１６の着脱時の取扱性が良くなるとともに、前面パネル１６には室内側排気口１４と比較して汚染の度合いの少ない室内側給気口１５のみを設けていることにより、前面パネル１６の汚れも少なく、また、前面がフラット状に形成されていることにより掃除性も良くなることとなる。   Further, the front panel 16 is held by the partition plate 23 and the holding rib 25 provided on the main body 13 side, so that the thickness can be reduced, the weight of the front panel 16 is reduced, and the front panel 16 is easy to handle when being attached or detached. As the front panel 16 is provided with only the indoor air supply port 15 that is less contaminated than the indoor exhaust port 14, the front panel 16 is less contaminated and the front panel is flat. The cleaning property is also improved by being formed in a shape.

また、排気開口１７は、本体１３の側部と前面パネル１６の間に形成されているので、排気開口１７が室内側給気口１５からより離れた位置に構成され、本体１３から吹き出される給気流と本体１３に吸い込まれる排気流がショートサーキットせず、排気開口１７が前面パネル１６によって前方から隠れた状態になるため、排気開口１７が前方からは全く見えないことになる。   Further, since the exhaust opening 17 is formed between the side portion of the main body 13 and the front panel 16, the exhaust opening 17 is formed at a position further away from the indoor air supply port 15 and blows out from the main body 13. Since the supply airflow and the exhaust flow sucked into the main body 13 are not short-circuited and the exhaust opening 17 is hidden from the front by the front panel 16, the exhaust opening 17 cannot be seen at all from the front.
