Problems solved by technology

[0003] Some washing machine users use inappropriate washing procedures because they do not pay much attention to the composition of the fabrics to be washed or do not have much concept of them, or the method of intelligently distinguishing the clothing category of the washing machine in the prior art is relatively rough and not accurate enough to correspond to Automatically selects an inappropriate washing program, which may result in fabric damage or less than ideal washing results

Embodiment Construction

[0014] Such as figure 1 As shown, after the washing program of the washing machine is started, the pressure value sampling process that has been executed throughout the program operation is executed, and then enters the execution of the segmented water intake process, and then performs the analysis of the static pressure value sampled when the washing tub stops rotating during the segmented water intake process Process the itinerary, and then execute the load weight and load type to determine the itinerary based on the analysis and processing results. After completing the judgment of load weight and load type, set washing parameters according to the judgment results, such as water temperature, drum speed and rhythm, washing time, rinsing time and rinsing water intake, and dehydration speed and dehydration time. Then, the program performs the cleaning process according to this, rinsing and drying several times until the washing program ends.

Abstract

A control method of a washing machine comprises the following steps: selecting and starting a washing procedure, executing a pressure value sampling stroke continuously executed at the beginning and the end of the program running, executing a step-feeding stroke, quantitatively flooding v L water in a washing barrel first and then rotating the washing barrel for T1 minutes during the step-feeding, or simultaneously rotating the washing barrel for T1 minutes during the process of quantitatively flooding water in the washing barrel, then stopping rotating the washing barrel for T2 minutes, then repeating the steps above for N times, later executing a static pressure value analysis and process stroke, wherein the static pressure value is sampled when the washing barrel stops rotating during the step-feeding stroke, executing a load weight and load type judging stroke according to the analysis and process result, setting washing parameter according to the load type and weight by the procedure, and finishing the washing procedure.

Description

【Technical field】 [0001] The invention relates to a control method of a washing machine, in particular to a method for automatically judging the load type and load weight of the washing machine. 【Background technique】 [0002] Most clothing is made of cotton, wool or man-made fibers, or a blend of the two. When washing clothes with a washing machine, due to the wear resistance and high temperature resistance of cotton materials, the strongest washing rhythm and relatively high washing temperature can be used for washing pure cotton fabrics to obtain the best stain removal effect; Temperature and washing intensity are more sensitive, and it is easy to change color and deformation, so we will choose a weaker rhythm and lower temperature when washing. Relatively speaking, the heat resistance and wear resistance of fabrics with blended components are between cotton and chemical fibers. When washing, you can choose a medium-intensity washing rhythm and a moderate temperature to ...
