(54) Washer-dryer apparatus


(57) A washer-dryer apparatus is offered in which the evaporation rate is high from the beginning of the pre-heat drying cycle and the spin-drying rate remain high and hence the pre-heat drying rate is high. That is, in a washer-dryer apparatus which performs the pre-heat drying cycle and normal drying cycle, feed water control means is provided for controlling the water supply to a water-cooled heat exchanger, by which the water supply is started, for example, a certain elapsed time after the start of the pre-heat drying cycle to keep the evaporation rate and the spin-drying rate high, providing increased pre-heat drying rate.
