Automatic detergent concentration monitoring method and system, storage medium and washing device

Abstract

The invention relates to an automatic detergent concentration monitoring method for a washing device. The method comprises the following steps of performing data acquisition: acquiring a current running program of the washing device; performing condition judgment: judging whether the run program is configured with a detergent concentration acquisition step or not; performing concentration monitoring: if the run program is configured with the detergent concentration acquisition step, executing operation of acquiring the volume V1 of a detergent in a monitored dilution chamber; feeding water to dilute the detergent to obtain a diluent, and obtaining the volume V2 of the diluent; acquiring a TOC value C2 of the diluted detergent in the diluent by a TOC sensor; and obtaining a TOC value C1 of the original detergent before dilution according to C1=C2*V2 / V1 so as to monitor the concentration of the detergent, wherein the concentration of the detergent comprises a TOC value, and the organic carbon mass concentration of the detergent is used for representing the concentration of active matter in the detergent. Through dilution monitoring, the concentration of the detergent is simply and accurately obtained, and a user can select the amount of the added detergent according to the concentration of the detergent. The invention further relates to a corresponding system and the washing device.

Description

technical field [0001] The invention relates to the technical field of detergent concentration monitoring for washing devices, in particular to a detergent concentration automatic monitoring method, system, storage medium and washing device. Background technique [0002] Washing devices, such as washing machines and dishwashers, generally use the weight and number of items to be washed to determine the required amount of detergent, so as to realize the definite dosage of detergent. In the use of most detergents in the market, it is often For example, 15g can be used to wash about 6 pieces of clothing, but the influence of the detergent itself is ignored. The content of active substances in the detergent is often related to its washing and decontamination ability, and the concentration of the detergent, which can also be called the concentration; different washing The decontamination ability of detergent is also different, and the amount of detergent used is also different fo...

Problems solved by technology

On the one hand, if the amount of detergent is too much, it will lead to a lot of residual detergent, the number of rinses will increase, and the water consumption will increase; on the other hand, if the amount of detergent is small, it will lead to problems such as unclean washing, which will affect the user experience

[0003] And the prior art usually adopts turbidity or conductivity to measure the quality of washing water in the washing device, and is rarely used for the concentration measurement of detergent; what turbidity characterizes is the degree to which suspended matter in water hinders light transmission, for water The monitoring effect of insoluble substances is better, but it cannot be monitored for soluble substances, and the concentration cannot be accurately reflected; conductivity is a parameter describing the difficulty of charge flow in substances, and it is characterized by the electrolyzable electrolyte content in washing water or detergent and the degree of difficulty, which characterize the degree of ionization of soluble substances, but the effective active substances in detergents are often surfactants, one end is the ionizable end of the hydrophilic group, and the other end is the non-ionizable end of the lipophilic group, and the conductivity is not accurate. Reflect the concentration; and the prior art part obtains the detergent concentration by directly measuring the detergent, but ignores the impact of the washing water on the detergent in the actual use environment, and the monitored detergent concentration cannot be directly and effectively used in the normal washing environment detergent dosage control
