Background technique

At present, washing machines are commonly used in people's daily life. At the same time, water-saving and energy-saving have been deeply rooted in people's minds. Usually people use large-capacity washing machines and small-capacity washing machines. When there are more clothes, large-capacity washing machines are used. Use less small clothes, such as socks, insoles, underwear, and other items, use a small-capacity washing machine; not only saves time, but also saves electricity and water. Avoid washing small pieces of clothing by hand, saving users' time and labor, and improving the intelligence of life.
