Abstract
Today, drum type washer dryer is widely spread drastically in Japan. The preferred requirements for washer dryer are lower electric consumption, and faster drying. Furthermore, it is very desirable to reduce wrinkles drastically after finished drying. We developed new high-quality-finish technology to smooth wrinkles with new concept of blowing high-speed hot air directly to cloths while drying. To optimize the parameters to get the satisfactory finish, we clarified the relationship experimentally between airflow speed, air quantity, cloths weight, and capacity of drum. To realize the condition above, we developed new high-pressure type fan motor, and applied it to the drum type washer dryer released in October 2007.
