Residual detection device for washing machine abstergent and detection method thereof

Abstract

The invention provides a residual detection device for washing machine abstergent and a detection method thereof. A water storage pipe is arranged on the upper end face of a water drainage pipe of an inner bucket of a washing machine, wherein the water storage pipe is communicated with the water drainage pipe. A detection device used for detecting resistance of a water solution of the water storage pipe is arranged inside the water storage pipe. An output end of the detection device is electrically connected with a program controller. A first water inlet pipe provided with a first water inlet valve and a second water inlet pipe provided with a second water inlet valve are arranged above the inner bucket of the washing machine, wherein the second water inlet pipe passes through a washing box, and the first water inlet valve and the second water inlet valve are respectively electronically with the program controller. The residual detection device for the washing machine abstergent is simple in structure and low in cost. The detection result of the detection method of the residual detection device for the washing machine abstergent is high in accuracy, stable in signals and capable of accurately judging concentration of the abstergent and judging whether residual of the abstergent is in clothes or not. Moreover, number of times of rinse can be increased according to actual conditions, so that damages, to the clothes and human bodies, of the abstergent can be reduced and the washing machine is more intelligent and humanized.

Description

Technical field [0001] The invention relates to the technical field of washing machines, and in particular to a detection device and a detection method for detergent residues on washing clothes. Background technique [0002] In the washing of clothes, appropriate surfactants are added as detergents to remove the dirt on the clothes. The clothes are caused by mechanical action such as the mutual friction between the water flow, the wall of the washing drum and the laundry to make the dirt attached to the clothes. 物detached. After the dirt on the clothes is removed, as the concept of healthy and green life has taken root in the hearts of the people, more and more attention has been paid to the problem of detergent residues on the clothes. Because there are detergent residues on the clothes, it not only harms the clothes, but also damages the human skin to a certain extent; the residual detergent is currently considered to be one of the main causes of human allergies.

AI Technical Summary

Problems solved by technology

However, increasing the number of rinsing times of clothes will inevitably waste water resources and electric energy, and increase the cost of use; and the increase of washing times will cause certain damage to the clothes themselves.

If the use of detergent is reduced, the washing effect of the clothes will be affected, and the clothes will not be clean
