AI Technical Summary

Technical Problem

Existing detergents and washing methods are not very effective at removing protein stains, especially when hydrogen peroxide concentration is high, which presents transportation limitations and cannot effectively balance the sterilization effect with the hydrogen peroxide concentration.

Method used

This product uses a stain remover with low concentration hydrogen peroxide combined with a unique washing control method. By adding the stain remover containing hydrogen peroxide to the washing program and adjusting the washing water level and temperature, the concentration of hydrogen peroxide is ensured to reach an effective bleaching concentration, thus achieving efficient stain removal.

Benefits of technology

It effectively removes colored and protein stains from clothes within the normal washing time, improving the user experience, avoiding transportation restrictions caused by high hydrogen peroxide concentration, and eliminating the need to extend the washing time.

Abstract

This invention provides a washing method and washing machine with sterilization function. After the first time period Δt1 of the washing program, when using a drum washing machine, a stain remover containing hydrogen peroxide is added, and a washing and sterilization process is executed. When using a top-loading washing machine, some washing water is drained to the minimum water level sufficient for normal washing before adding the stain remover containing hydrogen peroxide, and the washing and sterilization process is executed. The minimum water level is the amount of water that allows the washed clothes to tumble normally. The washing and sterilization process runs for a second time period Δt2. The sum of the first time period Δt1 and the second time period Δt2 is the washing program running time. The concentration of hydrogen peroxide in the stain remover does not exceed 7.8%. By adding low-concentration hydrogen peroxide to the stain remover, the problem of high hydrogen peroxide concentration in the stain remover cannot be transported is avoided. At the same time, combined with a unique washing control method, colored and protein stains on clothes can be efficiently removed within the normal washing time without extending the washing time, thus improving the user experience.
