PROBLEM TO BE SOLVED: To provide a washing and drying machine and a drying machine which can realize circulation drying while avoiding a temperature drop in a water tank or a housing, and prevent inner pressure in the water tank or the housing from being raised when feeding water, to prevent water leakage from a water supply port.SOLUTION: When pressure in the water tank is raised, air is discharged from a pressure reducing hole 69b provided in a connection duct 69 and the pressure in the water tank is reduced, thus preventing a check valve provided in a main water supply pipe connected to the water tank from being closed by the pressure in the water tank during a drying step, for example, to prevent water leakage from the water supply port when feeding water during the drying step. Dry air heated by a heater is supplied inside the water tank and a rotary drum through a blower fan 70 and is circulated in a dry air path and the water tank, thereby realizing efficient drying. |
