HEAT EXCHANGE VENTILATOR

PROBLEM TO BE SOLVED: To provide a heat exchange ventilator capable of facilitating removal work of a filter from a filter unit.SOLUTION: A heat exchange ventilator of this invention includes a casing formed in a box shape having an exhaust air passage and an air supply passage formed in an inside thereof, a heat exchange element exchanging heat between an exhaust air flow flowing through the exhaust air passage and an air supply flow flowing through the air supply flow passage, and a filter holding frame 16 disposed on an inflow side of the air supply flow or the exhaust air flow to the heat exchange element so as to hold a first filter 12a and a second filter 12b. The filter holding frame 16 has a first frame member 16a and a second frame member 16b connected by a hinge structure and storing the first filter 12a therebetween, and on the frame member disposed on an outflow side of the air supply flow or the exhaust air flow of the first frame member 16a and the second frame member 16b, guide ribs 101a and 101b for holding the second filter 12b from a side surface are vertically provided on an opposite side across the first filter 12a with respect to the frame member. 【課題】フィルタユニットからのフィルタの取り外し作業の容易化を図ることのできる熱交換換気装置を得ること。【解決手段】本発明は、排気風路と給気風路とが内部に形成された箱体形状のケーシングと、排気風路を流れる排気流と給気風路を流れる給気流との間で熱交換させる熱交換素子と、熱交換素子への給気流または排気流の流入側に設けられて、第１のフィルタ１２ａと第２のフィルタ１２ｂを保持可能とされたフィルタ保持枠１６と、を備え、フィルタ保持枠１６は、ヒンジ構造で連結されて互いの間に第１のフィルタ１２ａを収容する第１枠部材１６ａと第２枠部材１６ｂとを有し、第１枠部材１６ａおよび第２枠部材１６ｂのうち、給気流または排気流の流出側に設けられる枠部材には、その枠部材に対して第１のフィルタ１２ａを挟んだ反対側に、第２のフィルタ１２ｂを側面から保持するガイドリブ１０１ａ，１０１ｂが立設される。【選択図】図１８
