Abstract: Based on a certain model of drum washing machine, the basic principle of steam generation is explained, and steam is used as the research object, and then the standard clothes are treated with steam from the experiment. By comparing the degree of changes in the wrinkles and fluff of the clothes before and after the steam treatment, at the same time, the deodorization performance of the steam is evaluated by the degree of reduction of the odor of the clothes before and after the steam treatment, and the sterilization performance of the steam is evaluated by calculating the extinction rate of microorganisms. Studies have found that after steam treatment, clothing has a significant effect on wrinkle removal and bulkiness, with a wrinkle grade difference ≥3.5 and a bulkiness ratio≥0.95. In addition, the steam also shows a very impressive effect in deodorizing and sterilizing clothes, with a sterilization rate of ≥98%, and a deodorizing effect of ≥4.6. The study analyzed the effects of steam in detail and provided an accurate and reasonable basis for steam care of clothing.
