Detecting method for cloth quality and quantity of fuzzily controlled industrial washing machine

Abstract

The main principle of detecting the cloth quality and quantity is that the CPU first obtains and stored the initial water level H1, the water level H2 before the washing drum rotates and the water level H3 after the washing drum rotates, and calculates the water level differences S1=H2-H1 and S2=H3-H1; the CPU then obtains the pulse numbers M1 and M2 related to the inertial rotating numbers of the washing drum before and after water discharging; and the cloth quality and quantity is finally deduced based on the relationship between the cloth quality and quantity and the above said parameters.The said method has the advantages of accurate detection, high fuzzy control precision and high working efficiency of the washing machine.

Description

technical field [0001] The invention relates to an industrial washing machine using fuzzy control technology for washing control, in particular to a detection method for the two parameters of cloth quality and cloth quantity in the washing machine. Background technique [0002] Fuzzy control technology has been successfully applied in the household washing machine industry. Its main working principle is: through several sensors to separately detect and infer the fabric properties of the laundry to be washed—that is, the quality of the cloth, the weight of the laundry—that is, the amount of cloth , and the degree of dirt and nature of the laundry, etc., after the central processing unit obtains the above information, according to the data function relationship related to the above information stored in the fuzzy rule base, and through fuzzy reasoning and calculation , so that the washing machine adopts the best program - such as suitable main washing time, suitable water cons...

Problems solved by technology

[0008] But in fact, cloth impedance and water level difference are mutually influenced, and are related to cloth quality and cloth quantity, so the detection of cloth quality and cloth quantity will also affect each other. This parameter is not very accurate, which will directly affect the working precision and efficiency of fuzzy control washing machines; The sum of the weight of the components is much greater than the load——the weight of the laundry, so that the cloth impedance produced by different weights of dry-loaded cloth is relatively small, so the above-mentioned detection method used in the household washing machine cannot be directly applied to the industrial washing machine middle
