To provide a washing and drying machine capable of suppressing an AC power source current when a compressor is operated in a state where pressure inside the compressor is high, i.e., a state where the temperature of a coolant in the compressor is high.

The control part 121 of the washing and drying machine at least partially includes a period when a first motor 101 and a second motor 111 are simultaneously driven in a dehydrating process when the machine performs an operation including the dehydrating process and a drying process. The machine includes: a temperature detecting part 122 for detecting coolant temperature in the compressor 37. The control part 121 determines the upper limit value of the number of rotation in the second motor 111 in the dehydrating process according to the coolant temperature detected by the temperature detecting part 122.
