The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict. It will be understood that terms such as "having," "including," and "comprising," as used herein, do not preclude the presence or addition of one or more other elements or groups thereof.
The invention takes a washing machine as an example to introduce a drainage control method of a common washing device, washing water is required to be drained in main washing and rinsing of washing, the common washing water directly enters a sewer after being drained, but if environmental pollution exists, the washing water is required to be filtered and then drained; in addition, the drainage pipeline is easy to remain for drainage, and bacteria are easy to breed when the organic matter content in the washing water is high, and the filtering is also needed; therefore, a part of washing machines are provided with the drainage filter, but the filter is in a normally open use state, but if the drainage quality is qualified, the filter is in an overuse state, which is not beneficial to saving the washing cost; efficient use of the filter is required. In the washing process, in order to strengthen the washing effect, a spraying mechanism is often adopted, and washing water in a washing cylinder is circularly sprayed into the washing cylinder; or the last rinsing water after multiple times of rinsing is collected for the next main washing process, so that the water is saved; if the quality of the washing water of the circulation water is problematic. And the spraying mechanism is easy to block or influence the next main washing effect, so the water is filtered. It should be understood that, in a conventional washing device, the water after washing needs to be filtered and then discharged or recycled due to the problem caused by the water quality.
In one aspect, the present invention provides a drainage control method, as shown in fig. 1, including the steps of: s1, acquiring data, and acquiring a drain TOC value X in front of a drain pipe filter of the washing device; s2, judging the condition, namely judging whether the discharge TOC value X before the drain pipe filter is larger than a TOC requirement threshold Y; s3, executing drainage, and when the drainage TOC value X in front of the drainage pipe filter is larger than the requirement threshold Y, opening the drainage pipe filter, and filtering the drainage of the washing device by the drainage pipe filter and then flowing out of the drainage pipe; the demand threshold Y is the maximum allowable TOC for flow out of the drain. The TOC value represents the total amount of organic carbon in water, and compared with turbidity measurement, the TOC value not only can detect suspended organic carbon, but also can measure dissolved organic carbon in water, and can more comprehensively represent the quality of washing water, so that the accuracy of water quality judgment is ensured, and the judgment of organic matters is more suitable for drainage (circulating water) control, and drainage pollution and bacterial breeding are prevented; the TOC sensor before the filter is used obtains the TOC value, judges whether the TOC value meets the TOC value requirement after flowing out of the drain pipe or not to determine the starting of the filter, so that the filter effectively participates in drainage and filtration, the service life of the filter is prolonged, and the purpose of saving the washing cost is achieved.
Specifically, in the embodiment of externally draining the washing water, for example, after the washing is completed in the main washing process, the washing water needs to be drained, and the drain TOC value X before the drain pipe filter is acquired at the beginning of the drainage stage of the washing; judging whether the TOC value X of the drainage before the filter of the drainage pipe is larger than the drainageRequirement threshold Y1(ii) a When the TOC value X of the drainage before the drainage pipe filter is larger than the drainage requirement threshold Y1When the washing device is used, the drain pipe filter is opened, the drain water of the washing device flows out of the drain pipe after being filtered by the drain pipe filter, and is discharged out of the washing device through the outer discharge pipe; drainage demand threshold Y1The maximum TOC allowed by the washing device is discharged for the drainage, so that the washing drainage is ensured not to influence the environment; if X is less than or equal to Y1This indicates that no filtration is required to meet the TOC value requirements for discharge from the scrubbing unit.
It can be understood that, in order to ensure the completeness of the drainage program and protect the washing device, the TOC value after filtration is not considered after the filter is opened, and is directly discharged; because if the washing device is discharged and the filter is opened, the TOC detection result is still X > Y1If the water is not discharged, the washing water still stays in the washing device, and the washing device and the next washing are affected; the filter plays a certain purification role and protects the discharged water from polluting the external environment to a certain extent; to ensure the accuracy of the detection result, it can be set if X > Y after filtering1Retesting, setting test times, test time limit, and the like, wherein X is more than Y after exceeding the limit1The washing water is forcibly discharged and the user can be prompted in the system display for the forcible discharge of the washing water.
In some embodiments, such as a mode that washing water circulation spraying is needed, a drainage TOC value X before a drainage pipe filter is acquired at the beginning of a circulation water phase of washing; judging whether the TOC value X of the drainage before the filter of the drainage pipe is larger than the circulating water demand threshold Y2(ii) a When the TOC value X of the drainage before the drainage pipe filter is larger than the circulating water demand threshold Y2When the washing device is used, the drain pipe filter is opened, so that the drain water of the washing device flows out of the drain pipe after being filtered by the drain pipe filter and enters the circulating pipeline for circulating water; threshold value Y for demand of circulating water2The maximum TOC value allowed by the circulating water used by the washing device is ensured to meet the requirement of the circulating water without influencing the spraying quality; if X is less than or equal to Y1This indicates that no filtering is required to meet the TOC value requirement for the cycle.
In some embodiments, for example inAfter the last rinsing is finished, the washing water needs to be collected for the next main washing, after the steps of the embodiment, the filtered drainage water still needs to be judged, otherwise, the filtered drainage water still does not meet the requirements, and the filtered drainage water cannot be used for recycling water; therefore, the TOC value Z of the drain filtered by the drain filter is required to be acquired; judging whether the TOC value Z of the drainage filtration is larger than the threshold value Y of the requirement of the circulating water2(ii) a If the TOC value Z of the drainage filtration is larger than the circulating water demand threshold Y2If the filtered water does not meet the requirement of the circulating water, the drained water flows out of the drain pipe and is drained out of the washing device, and the drained water is not used for circulation; if the TOC value Z of the drainage filtration is less than or equal to the circulating water demand threshold Y2If the drainage quality meets the requirement of the circulating water, the drainage flows out of the drainage pipe and then enters a circulating pipeline for circulating water; thus, the quality of the recycled water is ensured, and the washing effect is improved.
In some embodiments, the recycled water represented above may be: the circulating water in the spraying washing mode is used for supplying the washing water in the washing device in the washing process to the spraying mechanism and then enters the washing device, and the requirement threshold value Y of the circulating water at the moment2The TOC maximum value allowed by spraying is the washing water quality meeting the spraying and washing requirements; or store the washing water for the circulation washing at the end of rinsing, e.g. next main washing, circulation water demand threshold Y2The maximum value of TOC allowed for the circular washing, specifically, the value which can meet the water inlet requirement of the next main washing; of course, other drainage modes are also possible, for example, the drainage is not discharged into a sewer, but is collected for other (flower watering and toilet flushing) domestic water after being discharged, and TOC threshold value judgment can also be adopted; the washing circulation can also be that washing water of washing enters the flocculation container for recycling after treatment, and the TOC threshold value is used for judging whether the washing water can enter the flocculation container.
In some embodiments, for the judgment of the service life of the filter, the TOC value before and after filtering may be adopted to judge whether the filter has a filtering effect, so as to determine whether the filter needs to be replaced or cleaned, specifically, after the drain pipe filter is opened, the drain filtered TOC value Z filtered by the drain pipe filter is obtained; judging whether the TOC value Z of the drainage filtering is more than or equal to the TOC value X of the drainage before the drainage pipe filter; if the TOC value Z of the drainage filter is not less than the TOC value X of the drainage before the drainage pipe filter, the abnormal reminding of the drainage filter is executed, and a user can clean or replace the filter in time according to the reminding, so that the normal use of the filter is ensured, and the waste and the over-limit use of the filter are not caused.
The drainage control method of the present invention is explained with reference to the logic diagrams of fig. 2, 3, 4, and 5.

While embodiments of the invention have been disclosed above, it is not limited to the applications listed in the description and the embodiments, which are fully applicable in all kinds of fields of application of the invention, and further modifications may readily be effected by those skilled in the art, so that the invention is not limited to the specific details without departing from the general concept defined by the claims and the scope of equivalents.
The foregoing description has been directed to specific embodiments of this disclosure. Other embodiments are within the scope of the following claims. In some cases, the actions or steps recited in the claims may be performed in a different order than in the embodiments and still achieve desirable results. In addition, the processes in the figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In some embodiments, multitasking and parallel processing may also be possible or may be advantageous.
In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Hardware Description Language), traffic, pl (core universal Programming Language), HDCal (jhdware Description Language), lang, Lola, HDL, laspam, hardward Description Language (vhr Description Language), vhjhdu (Java Hardware Description Language), and vhigh-Language (Hardware Description Language). It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.
