Preferably, if the chelating agent is included in the combination scheme of the detergent raw material, the chelating agent is preferentially fed.

[0119] For example: when R0 is 200ppm, if the obtained hardness R >= 200ppm, the chelating agent needs to be added, and the chelating agent accounts for 0.1% of the total amount of the fed raw material.

[0120] In the present embodiment, if the obtained hardness R is greater than or equal to the preset hardness R0, it indicates that the hardness of the washing water is large, at this time, the chelating agent is included in the combination scheme of the detergent raw material, the molecules of the chelating dispersant can be dissociated into H+ in water, become anion with negative charge on the surface and complex with Ca2+, Mg2+, Fe2+ and other metal ions in the solution, form a stable complex, prevent hard water from combining with anionic surfactants and losing effect; otherwise, the chelating agent does not need to be fed, and waste of the chelating agent is avoided.

Among them, the A cavity 1 contains anionic surfactant sodium dodecyl benzene sulfonate, the B cavity 2 contains fatty alcohol polyoxyethylene ether AEO-7, the C cavity 3 contains amphoteric surfactant dodecyl dimethyl amine oxide, the D cavity 4 contains 40% sodium hydroxide lye, the E cavity 5 contains fragrance solution or any product that can leave fragrance, the F cavity 6 contains chelating agent, the G cavity 7 contains white fiber cellulase, the H cavity 8 contains protease, the I cavity 9 contains lipase, the I1 cavity 10 contains mannanase, the I2 cavity 11 contains amylase, and the I3 cavity 12 contains pectinase.

[0124] In this embodiment, when it is judged that the dirt type is a low-level dirt type with low washing difficulty, the total amount of the detergent raw material is first calculated, and the calculation method is: total amount of detergent raw material (g) = 0.2 * (2 * weight of the to-be-washed object (kg) + 7).

[0125] Subsequently, the detergent raw material is dispensed according to the combination scheme shown in the following Table 1:

[0126] Table 1:

[0127] A B C D E Dust 50％ 0 50％ 0 According to user selection Protein 50％ 50％ 0 0 According to user selection Sebum 20％ 70％ 0 10％ According to user selection

[0128] In this embodiment, when it is judged that the dirt type is a low-level dirt type with low washing difficulty, if the dirt degree is greater than or equal to the preset dirt degree Q0, the detergent raw material is dispensed according to the combination scheme shown in the following Table 2:

[0129] Table 2:

[0130]

[0131] Among them, if the user selects to dispense E (fragrance solution), E (fragrance solution) is dispensed when the washing apparatus enters the last rinse or washing, so as to ensure that the fragrance solution fully plays its role.

[0132] In this embodiment, when it is judged that the dirt type is a high-level dirt type with high washing difficulty, the total amount of the detergent raw material is first calculated, and the calculation method is: total amount of detergent raw material (g) = 0.4 * (2 * weight of the to-be-washed object (kg) + 7).

[0133] Subsequently, the detergent raw material is dispensed according to the combination scheme shown in the following Table 3:

[0134] Table 3:

[0135]

[0136]

[0137] In this embodiment, the detergent raw material combination scheme corresponding to the dirt type is selected according to the obtained dirt type, so that the detergent raw material can be used to wash the dirt in a targeted manner, the washing efficiency is improved, and unnecessary waste of detergent raw material components is avoided.

[0138] As an embodiment of the present embodiment, the washing equipment control method comprises:

[0139] The weight of the washing object (clothes) is obtained;

[0140] The total weight of the detergent raw material to be added is calculated;

[0141] The combination scheme of Table 2 is added, and the addition sequence is: the alkali solution 40% sodium hydroxide in the D cavity 4 and the chelating agent in the F cavity 6 are preferentially added, wherein whether the F is added depends on the hardness of the washing water; after the D and F are added for a set time (for example, 1 min), the A, B, C, and D are added according to the combination scheme; after the A, B, C, and D are added for a set time (for example, 1 min), the I, I1, I2, and I3 are added according to the combination scheme.

[0142] In this embodiment, the alkali solution and the chelating agent are added first, which can ensure that the surfactant raw material can immediately take effect and play the maximum role when it is added. The reason for adding the surfactant and then adding the active enzyme is that the surfactant can enhance the permeability of the active enzyme to the clothes after being dispersed in the washing barrel of the washing equipment, and some surfactants have an impact on the enzyme. Adding the surfactant first and then stirring to reduce the local concentration can effectively protect the active enzyme.

[0143] The present application changes the current situation of additive detergents for washing equipment. The addition of detergent raw materials can achieve the effect of 100% concentrated detergent. Different detergent raw materials with different proportions are added for washing different stains. The proportion of the raw materials is dynamically adjusted to improve the washing efficiency. The present application distinguishes the characteristics of various detergent raw materials, so that they can be added in stages during washing, and the detergent raw materials can play the maximum effect in each stage. In addition, the order of adding the detergent raw materials is also optimized according to their own characteristics and user usage habits, and the user experience effect is better.

[0144] The above only describes the preferred embodiments of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above with the preferred embodiments, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above-mentioned technical content without departing from the scope of the technical solution of the present application, and equivalent embodiments with equivalent changes are equivalent.
