Background
Proper washing powder is added to clean clothes to remove dirt of the clothes, and the dirt attached to the clothes is separated by mechanical actions such as water flow, mutual friction and mutual impact between the wall of the washing drum and the washed clothes in the washing machine. After the dirt on the clothes is removed, along with the idea of healthy and green life, the residual problem of the washing powder remained on the clothes is paid more and more attention. The washing powder is remained on the clothes, so that the clothes are damaged, and the skin of a human body is further damaged to a certain extent; residual washing powder is currently considered to be one of the main causes of human allergy.
With the green and low-carbon concepts entering the lives of people, the washing machine industry is confronted with a new technological innovation. Rinsing performance, i.e., the ability of the washing machine to remove laundry powder, is one of the important performance properties of the washing machine. The rinsing effect of the washing machine is determined by detecting the alkalinity of the residual rinsing liquid (the residual liquid from the high-speed dehydrator) of the washed clothes. The alkalinity detection on clothes is troublesome, the alkalinity of residual washing powder in a washing machine is detected by detecting the alkalinity of the residual washing powder in the washing machine after the washing of the washing machine at present, after the same clothes are washed under the same conditions, if the alkalinity is detected to be higher, the rinsing capacity of the washing machine is proved to be poorer, and if the alkalinity is detected to be higher, the rinsing capacity is better. At present, for the alkalinity detection of residual washing powder in the washing machine, a small amount of water is manually injected into the washing machine, and the detection is carried out after the water is collected, so that the operation is troublesome, and the detection of a large batch of washing machines is not facilitated.
