All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

A method for enhancing fuzzy weighing of a pulsator washing machine comprises the following steps:

s1, automatically adjusting the gear of the washing machine to 1 gear, and installing a flowmeter on the washing machine to detect the actual water inflow of the washing machine;

s2, judging whether the actual water inflow in the gear is larger than the set water level value in the gear, and if so, executing a step S3;

s3, increasing the water level step by step in sequence, judging whether the additionally increased flow of the washing machine is larger than the water level value set by each gear step after the gear is increased, if so, continuously increasing the gear, and executing the step S4, otherwise, indicating that the water overflows the clothes, and stopping continuously feeding the water;

s4, judging whether the current gear in the step S3 is equal to the N-2 gear or not, if the current gear is not equal to the N-2 gear, repeatedly executing the step S3 until the current gear is equal to the N-2 gear, and if the current gear is equal to the N-2 gear, executing the step S5;

s5, judging whether the water level of the current gear overflows the clothes, if so, stopping continuously feeding water, and if not, executing a step S6;

s6, shifting from the current gear N-2 to the gear N, wherein the water volume in the gear N is lower than the set full water bucket volume;

and S7, reducing the half-gear water level under the washing gear during rinsing each time.

Supposing that the washing bucket has x cloth, x is 3, the water absorption of each cloth is Qx, the water absorption of different cloths is different, and in the washing and water adding process of the washing machine, when the washing machine is in a first gear, water adding judgment is carried out until water adding judgment of an mth gear is carried out, a preset water level value corresponding to each increased gear is Lm, the actual water inflow of the flowmeter is Sm, and calculation equations under different gears are obtained according to the fact that the mass of water is equal to the volume of the water:

in the 1 st gear, ρ ═ (S1-L1-V) (P1 × Q1+ P2 × Q2+ … + Px × Qx) × K1,

in the 2 nd gear, ρ ═ S (S2-L2-V) ═ K2 (P1 × Q1+ P2 × Q2+ … + Px Qx),

……

in the mth gear position, ρ ═ (Sm-Lm-V) (P1 × Q1+ P2 × Q2+ … + Px × Qx) × Km

Where Px is a ratio of a weight of laundry corresponding to the x-th fabric type to a total weight of laundry, P1+ … + Px is 1, Km is a weight of laundry in which the m-th stage is immersed in water, and ρ is 1kg/L is 1

The water absorption of each cloth is different, and the measured water absorption is recorded in a warehouse, wherein the water absorption of the hemp, the cotton and the polyester fiber is respectively 1.0, 2.0 and 0.5;

in the actually measured equation, only P, Km is data to be measured, x is preset data and is represented as the type of cloth, V is water amount corresponding to 0 gear, the water absorption amount of pure cotton cloth, linen cloth and chemical fiber among various gears is preset, and according to the preset value, the ratio Tm is Km-Km-1/Km-1-Km-2(m is more than or equal to 2) of each increased weight is carried out.

In actual test, if the deviation between the actual Tm value and the preset value is not more than 5%, the difference of cloth in the washing machine can be judged to be small at the moment, clothes in the barrel can be judged directly through Km and a water level gear, namely due to the density problem of cotton, hemp and chemical fiber, after the gear, namely the approximate volume of the clothes, is determined, the water absorption rate of the clothes is judged through measuring the water absorption capacity, and therefore judgment is carried out. If the water absorption is larger than the linen normal value at the water level of 5, comparing the cotton cloth in a database, judging by the cotton cloth, if the water absorption is 1.8, judging that more than 80% of cotton exists in the clothes, if the water absorption is similar to the linen normal value, judging by the linen, and selecting a program according to the judgment;

meanwhile, according to the above determination, a large deviation occurs when the water absorption rate is at the middle value, that is, if it is measured to be 1.5, 30% chemical fiber or 50% hemp and corresponding cotton may occur. A second situation may actually occur: the clothes are not mixed uniformly, and the clothes may be stacked up and down. The difference value of the layering of cotton, chemical fiber and hemp at different water level stages is reversely deduced, namely the maximum value is 0.5/2.0-0.25.

Accordingly, if the deviation of the Tm actual value is more than 25% of the preset value, the maximum difference section and the minimum difference section are compared to judge that the clothes are not mixed uniformly and are likely to be stacked up and down, the clothes percentage of each section is judged by the method and the Km values of the maximum difference section and the minimum difference section, if cotton and linen are on the lower part, soft washing is carried out, and if cotton and linen are on the upper part, soaking washing is carried out;

if the deviation range of the Tm actual value and the preset value is between 5% and 25%, the clothes of all sections are judged, and the programs are selected comprehensively after the clothes between each gear are approximately judged.

And establishing a database through the equation, making databases of cotton/hemp/chemical fibers with different kilogram segments, and comparing the databases during actual use so as to neglect the influence of the distribution of the clothes on a judgment mode and judge the weight and the distribution of the clothes.

The foregoing is merely exemplary and illustrative of the principles of the present invention and various modifications, additions and substitutions of the specific embodiments described herein may be made by those skilled in the art without departing from the principles of the present invention or exceeding the scope of the claims set forth herein.
