To obtain prescribed washing performance and drying performance by smoothly starting a drum in a short time so as to suppress the over shoot of drum revolution to be low so as to prevent wash from being stuck to the inner wall of the drum with respect to a washing and drying machine for washing, rinsing, dehydrating, and drying wash within the drum freely rotatably arranged with a nearly horizontally provided rotary shaft as a center.

The drum housing wash and rotatable with a nearly horizontally provided rotary shaft as a center is included in an outer tank, elastically supported in a washing machine main body and driven by a first motors 13. The revolution of the drum or the first motor 13 is detected by a revolution detecting means 28 and the output of the means 28 is inputted to a continuing time control means to control the continuing time of a power semiconductor module 19 to control the revolution of the drum or the first motor 13. The continuing time control means detect the nearly half revolution of the drum at the time of starting the drum and switches from a first revolution controlling method to a second revolution controlling method.
