PROBLEM TO BE SOLVED: To provide a washing and drying machine including a novel blower fan unit in which noise reduction and improvement in an air blowing amount have been achieved.SOLUTION: A tongue end part 62 of a scroll surface 60 is inclined toward an impeller 52 side, and a gap between the tip of the tongue end part 62 and an outer peripheral surface of the impeller 52 is made to be narrow. Also, a place from the tongue end part 62 to a final end part 61 is divided into two with a predetermined scroll surface change position 64 being a boundary, and an increase ratio of gap length between the scroll surface and the impeller from the tongue end part 62 to the scroll surface change position 64 is defined as a first gap length increase ratio, and an increase ratio of gap length between the scroll surface and the impeller from the scroll surface change position 64 the to the final end part is defined as a second gap length increase ratio, the scroll surface is formed by having the relationship of the first gap length increase ratio>the second gap length increase ratio.SELECTED DRAWING: Figure 5 【課題】騒音の低減及び送風量の向上を図った新規な送風ファンユニットを備えた洗濯乾燥機を提供することにある。【解決手段】スクロール面６０の舌端部６２を羽根車５２側に向けて傾斜させて舌端部６２の先端と羽根車５２外周面の間の隙間を狭くする。また、舌端部６２から最終端部６１までを所定のスクロール面変更位置６４を境にして２分割し、舌端部６２からスクロール面変更位置６４までのスクロール面と羽根車間の隙間長さの増加割合を第１隙間長さ増加割合とし、スクロール面変更位置６）から最終端部までのスクロール面と羽根車の間の隙間長さの増加割合を第２隙間長さ増加割合とした時、第１隙間長さ増加割合＞第２隙間長さ増加割合の関係を有してスクロール面を形成した。【選択図】図５
