WASHING AND DRYING MACHINE

To provide a washing and drying machine capable of mixing ozone preferably into the air flowing in a circulation passage, while suppressing generation of rust in a heat exchanger.SOLUTION: A drum type washing and drying machine 1 includes: a first heat exchanger and a second heat exchanger which are arranged in a circulation passage, and each of which has a metal fin; an ozone generator 141 for generating ozone from air; and a storage tube 142 in which one end surface 142a is opened and the other end surface 142b is closed, and in which the ozone generator 141 is stored. The circulation passage includes a cylindrical second duct 114b in which an intake-port 114c where ozone is taken in is provided, further on the downstream than the first heat exchanger and the second heat exchanger. At the storage tube 142, an opening part 145 opening to the outside part is provided. In the storage tube 142, the one end surface 142a is connected to the intake-port 114c in such a manner that an angle R1 of an axis line L2 of the storage tube 142 in the direction in which the air flows in the second duct 114b with respect to an axis line L1 of the second duct 114b becomes an acute angle or a right angle.SELECTED DRAWING: Figure 3 【課題】熱交換器に錆が発生することを抑制しつつ、循環路を流れる空気に良好にオゾンを混合させることが可能な洗濯乾燥機を提供する。【解決手段】ドラム式洗濯乾燥機１は、循環路内に配置された、金属製のフィンを有する第１熱交換器および第２熱交換器と、空気からオゾンを生成するオゾン発生器１４１と、一端面１４２ａが開放されるとともに他端面１４２ｂが閉塞され、オゾン発生器１４１が収容される収容管１４２と、を備える。循環路は、第１熱交換器および第２熱交換器よりも下流に、オゾンが取り込まれる取込口１１４ｃが設けられた筒状の第２ダクト１１４ｂを有する。収容管１４２には、外部に開口する開口部１４５が設けられる。収容管１４２は、第２ダクト１１４ｂの軸線Ｌ１に対する、第２ダクト１１４ｂを空気が流れる方向における収容管１４２の軸線Ｌ２の角度Ｒ１が、鋭角または直角となるように、一端面１４２ａが取込口１１４ｃに接続される。【選択図】図３
