The big items of washing machine include sheets, bedspreads, blankets and other big items. But before cleaning, you need to look at the signs on the clothes. For sheets, bedspreads and other large items, it is difficult to wash them directly in the washing machine, and the washing time is long. The best way is to soak for 20 minutes first, which will make the washing effect better and shorten the washing time.

Washing machine is a kind of cleaning appliance that uses electrical energy to generate mechanical action to wash clothes. According to its rated washing capacity, it can be divided into two categories: household use and collective use. China stipulates that the washing capacity below 6 kg belongs to domestic washing machines: domestic washing machines are mainly composed of box, washing and dewatering barrels (some are separated), transmission and control systems, and some are equipped with heating devices. Washing machines generally use water as the main cleaning liquid, which is different from using special cleaning liquid and dry cleaning which is usually handled by special personnel.

Mechanical force, washing liquid and water are three elements in the washing process of washing machine. The mechanical force generated by the moving parts of the washing machine and the action of washing liquid separate dirt from clothing fibers. Heating the washing liquid can enhance the decontamination effect. Different fabrics have different suitable liquid temperatures, and the main indicators reflecting the washing performance of washing machines (that is, the ability to wash clothes) are washing rate (or washing ratio) and fabric wear rate.
