Problems solved by technology

[0003] Because the degree of soiling of the clothes that need to be washed is different each time, it will inevitably affect the laundry effect. The clothes that are slightly dirty will be washed excessively, and the clothes will suffer unnecessary wear and tear, and cause waste of water, electricity, and detergent ; and more dirty clothes will cause washing
This also results in the low level of intelligence of the washing machine, which cannot be truly fully automatic.

Embodiment Construction

[0019] The four washing gears of the washing machine are preset: U1, U2, U3, U4, the range of U1 is between 0.15 and 0.25, the range of U2 is between 0.25 and 0.45, the range of U3 is between 0.45 and 0.65, and the range of U4 is between 0.65 and 1.05 between.

[0020] Choose a washing time of 3 minutes or 5 minutes.

[0021] Judgment process such as figure 1 As shown, put the laundry into the inner drum of the washing machine. After the washing machine system is weighed, it is filled with water and pre-washed for 3 minutes. The turbidity degree UA of the washing water is measured by the turbidity sensor;

[0022] Then pre-wash for 5 minutes, and measure the turbidity UB of the washing water through the turbidity sensor;

[0023] Calculate the difference U0=UB-UA.

[0024] Compare the calculation results U0, U0 with the preset gears, and select the corresponding laundry gears.

Abstract

The invention relates to a washing machine control method, which is particularly characterized in that the corresponding clothes washing control method is selected after the smudgy degree of clothes is judged. According to the method, firstly, the turbidity degree of water in the starting time period of the clothes washing is compared, the smudgy degree of clothes to be washed is distinguished, and then, the washing time, the washing intensity, the detergent addition quantity, the rinsing time and the like are regulated according to the smudgy degree of the clothes. The corresponding clothes washing procedure is selected according to the smudgy degree of the clothes, the clothes washing time of cleaner clothes can be reduced, the washing time of dirtier clothes is increased, and the clothes washing efficiency is improved.

Description

technical field [0001] The invention relates to a control method of a washing machine, specifically, selecting a corresponding laundry control method after judging the degree of dirtiness of the clothes. technical background [0002] At present, most fully automatic washing machines manually select a clothing material program on the computer board after adding clothing to the washing bucket when doing laundry. Then, according to the material and weight of the clothes, the computer board presets the washing time, washing intensity, amount of detergent added and rinsing times, etc. for washing action. [0003] Because the degree of soiling of the clothes that need to be washed is different each time, it will inevitably affect the laundry effect. The clothes that are slightly dirty will be washed excessively, and the clothes will suffer unnecessary wear and tear, and cause waste of water, electricity, and detergent ; And more dirty clothes will cause washing not clean. This a...
