WASHING AND DRYING MACHINE

PROBLEM TO BE SOLVED: To provide a washing and drying machine which eliminates unevenness in a sterilization and deodorization effect and which performs efficiently.SOLUTION: A washing and drying machine includes: a heat pump unit 12 for generating drying air supplied to a drum 2; a circulation blower path 11 for connecting an outer tub 3 and the heat pump unit 12 and circulating the drying air; a blower fan 9 for blowing air in the circulation blower path 11; ozone generation means 13 for supplying ozone in the circulation blower path 11; mist generation means 14 for supplying particulate water in the circulation blower path 11; and control means for controlling a series of steps sequentially. The control means, in a sterilization and deodorization step, timely drives the blower fan 9, the ozone generation means 13 and the mist generation means 14, and discharges the ozone and the particulate water with respect to clothes and the like in the drum 2. Thereby, as ozone can be made to act with respect to various germs and organic matter adhering to the clothes, small articles and the like, in an environment where the humidity in the drum 2 is increased, sterilization and deodorization action can be performed efficiently and surely. 【課題】除菌・消臭効果のムラを無くし、効率良く行なう洗濯乾燥機を提供すること。【解決手段】ドラム２内に供給する乾燥用空気を生成するヒートポンプユニット１２と、外槽３とヒートポンプユニット１２を連結して乾燥用空気を循環させる循環送風経路１１と、循環送風経路１１内に送風する送風ファン９と、循環送風経路１１内にオゾンを供給するオゾン発生手段１３と、循環送風経路１１内に微粒子水を供給するミスト発生手段１４と、一連の工程を逐次制御する制御手段とを備え、制御手段は、除菌・消臭工程において、送風ファン９、オゾン発生手段１３、およびミスト発生手段１４を適時に駆動させて、ドラム２内の衣類等に対してオゾンと微粒子水を放出する構成とすることにより、ドラム２内の湿度を上昇させた環境で、衣類、小物などに付着した雑菌、有機物に対してオゾンを作用させることができるので、除菌・消臭作用を効率よく確実に行うことができる。【選択図】図１
