PROBLEM TO BE SOLVED: To provide a drum type washing and drying machine which can eliminate that a valve body and a valve holder are fixed during a reserved operation for a long period of time in a state where undiluted solution of a detergent flows out and adheres to contact surfaces of a valve body and a valve holder and water leaks from the front side of the washing and drying machine during supplying water by a reverse flow of water during supplying water.SOLUTION: The drum type washing and drying machine comprises: a detergent case 14 for supplying a detergent; and a connecting tube 19 communicating the inside of an outer tub 3 with the detergent case 14. The connecting tube 19 is provided with a valve body 22 formed with an elastic body and having a structure which opens in a direction from the detergent case 14 to the outer tub 3 and closes in the opposite direction, and is locked on an end surface side in a direction of the outer tub 3 of a substantially cylindrical valve holder 24 one end of which is arranged in a substantially vertical direction. The valve body 22 is configured for always tightly contacting the end surface 25 of the valve holder 24 by an urging force by the elasticity and is provided with a substantially cylindrical receiving part 27 at the center upper part. On the inner surface of the valve holder 24, a lib is formed in a substantially concave cone shape having an inclined side in an inner periphery so that the detergent flows in the receiving part 27. |
