Problems solved by technology

[0003] Since the types of stains on the clothes that need to be washed are different each time, choosing the same washing method for different types of stains will easily cause lightly soiled clothes to be over-washed, and the clothes will suffer from excessive wear and tear, and cause water, electricity, and washing. The waste of detergent; and the dirty clothes will cause the washing to be unclean, which also leads to the low level of intelligence of the washing machine, and it cannot be truly fully automatic.

Embodiment Construction

[0019] The computer board of the washing machine pre-sets the corresponding relationship of the spectral band ranges corresponding to various stains: U1, U2, U3, U4, U5, and the above bands include all the band ranges of the near-infrared spectrum. The U1 band is 780-1000nm grease as the main stain component, the U2 band is 1000-1400nm perspiration as the main stain component, U3 is 1400-1800nm ​​food as the main stain component, U4 is 1800-2200nm blood stains as the main stain component, U5 other and mixed stains at 2200-2526nm.

[0020] According to attached figure 1 , the method of identifying the type of clothing stains is:

[0021] 1) Put the laundry into the inner drum, start the washing machine, the motor drives the inner drum to rotate, and the near-infrared spectrum sensor scans the clothes at the same time;

[0022] 2) The near-infrared spectrum sensor scans the clothes to obtain the corresponding band U0, which is transmitted to the computer board, and the obtaine...

Abstract

The invention relates to a control method of a washing machine and particularly a method for identifying stain types of clothes and choosing corresponding washing control methods. The method specifically comprises the steps of weighing a washing machine system, scanning the clothes by using a near infrared spectral sensor, obtaining a spectral value U0, comparing the U0 with a preset wave band, and choosing a corresponding washing method according to a comparison result. According to the technical scheme, the dirtiness degree of the clothes to be washed is detected automatically, based on the weight of the clothes, parameters such as the washing dose, the washing time and the washing intensity are chosen and added automatically through a computer board, the washing efficiency and the intelligent level of the washing machine are improved.

Description

technical field [0001] The invention relates to a control method of a washing machine, specifically, selecting a corresponding laundry control method after identifying the type of stains on 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] Since the types of stains on the clothes that need to be washed are different each time, choosing the same washing method for different types of stains will easily cause lightly soiled clothes to be over-washed, and the clothes will suffer from excessive wear and tear, and cause water, electricity, and washing. The waste of detergent; and the dirty clothes will cause the was...
