ドラム式乾燥機及びドラム式洗濯乾燥機
Document Type and Number:
Japanese Patent JP4423323
Kind Code:
B2
Abstract:
The object of the invention is to provide a dryer or a wash dryer for effectively most of motor output in the kinetic energy of warm wind on dryer or a wash dryer during dry running. According to the electric power consumption sum of a heater and the motor, because the commercial power is usually controlled below 15A, if the motor output becomes larger, the electric power consumption if the heater and the output larger part accordingly drops, so that the heat is insufficient. So that more increase to the motor output, the heat during dry running will be more insufficient. Under low pressure, most of motor output is used to wind speed, air volume or the like kinetic energy, thus it can not constitute the heat source for heating the warm wind. In order to make the motor output as the heating source of the warm wind, the invention is characterized in that the impeller of the air blast unitary is in high-speed rotation, the invention improves the pressure of the warm wind to compress, and uses its compression heat during dry running.
