最近,美国林沙大学的一批研究人员成功地制成了一种微波干衣机。据称,其原理与微波炉相似,干衣速度快,是传统式电热干衣机的两倍多。传统式电热干衣机的干衣过程分为三个阶段:首先,电力发热,将干衣简内的空气温度提高;然后,热空气使衣服内的水分蒸发;最后再把水蒸气排除。如果使用微波干衣机,则空气加热阶段可省去,微波直接把衣服内的水分加热蒸发,不仅加快了干衣速度,而 Recently, a group of researchers at Linsa University in the United States successfully manufactured a microwave dryer. It is said that the principle is similar to that of a microwave oven, and the drying speed is faster than twice that of a conventional electric dryer. The drying process of a conventional electric dryer is divided into three stages: First, the electric heating generates heat, which increases the temperature of the air in the drying clothes. Then, the hot air evaporates the moisture in the clothes. Finally, the water vapor is eliminated. If a microwave dryer is used, the air heating stage can be omitted. The microwave directly heats and evaporates the moisture in the clothes, not only speeding up the drying speed, but also
