Description

Water quality detection pipeline, system, intelligent water purifier and intelligent household appliance

Technical Field

The embodiment of the utility model provides a relate to water quality testing technical field, especially relate to a water quality testing pipeline, system, intelligent water purifier and intelligent household electrical appliances.

Background

Along with the improvement of living standard of people, people pay more and more attention to self health problem, and in daily life, water is the most indispensable material of people, but along with the environmental degradation, drinking water quality also can not satisfy people's pursuit to health more and more. In China, raw water leaving a tap water plant meets the standard of a new national standard, but the water is a unique medium and is particularly easy to breed harmful substances such as bacteria, so that the bacteria in the water body need to be inhibited and killed in the process of conveying the tap water pipe network. Water plants typically add chlorine-containing disinfectants, such as chlorine gas, sodium hypochlorite, or other solid chlorine disinfectants, during the purification of the source water. The hypochlorous acid with strong oxidizing property formed in water can effectively kill bacteria and other pollutants, and prevent end resident users from getting ill due to bacteria exceeding standards, such as diarrhea and belly pulling caused by bacteria exceeding standards. However, the hypochlorous acid disinfectant cannot be excessive. Research shows that excessive residual chlorine in water after chlorine is used for sterilizing drinking water can cause high incidence of cancers such as esophagus cancer, stomach cancer, rectal cancer, bladder cancer, prostate cancer and the like. There is some evidence that the development of childhood leukemia may be a great concern with the long-term consumption of high chlorine drinking water. Also, there are diseases that are very sensitive to chlorine. If residual chlorine cannot be removed, after coffee, tea or soup drunk by people every day is boiled and drunk, the amount of carcinogens is increased by 3-4 times. Therefore, it is desirable that the tap water be filtered by a water purifier and then drunk. The water purifier can not only filter residual chlorine remained in tap water, but also filter mineral substances dissolved in water, wherein heavy metals with great toxicity to human bodies exist, and organic pollutants in water can also be filtered.

The following takes a water purifier as an example to illustrate the technical problems of the existing water-using household appliances for water quality health. At present, water purifiers on the market are generally subjected to layer-by-layer filtration and sterilization treatment, so that people can directly drink tap water. The filter element is the core component of water purifier, generally includes multistage filter core, and the first grade is PP melts and spouts the filter element (polypropylene superfine fiber hot melt entangles and makes), removes large granule such as silt, iron rust. The second stage adopts a granular activated carbon filter element to remove peculiar smell and residual chlorine. The third stage adopts an RO reverse osmosis filter element, the filtering precision can reach one ten thousandth micrometer (0.0001 mu m), and antibiotics, organic matters, heavy metals, water scale, bacteria, viruses and the like can be removed by water through the tiny filtering holes of the filter element. The fourth grade active carbon granules further improve the taste.

The water purification effect of water purifier relies on the filter core performance to guarantee, along with the increase of filter core live time, the purifying effect of filter core constantly descends and damages the inefficacy even, leads to a water quality of water variation, and the pure water quality of water that the water purifier produced this moment is no longer pure, and the consumer can't know, for example: pH 6.5-8.5, Oxidation Reduction Potential (ORP) value is an important comprehensive indicator that less than 300mV is needed to be more beneficial for health, conductivity or Total Dissolved Solids (TDS) value indicates when RO filtration module is to be replaced, residual chlorine value indicates when activated carbon module is to be replaced and whether disinfectant residue is out of specification. The filter element replacement of the existing water purifier is basically a filter element replacement period method suggested according to installation time or total purified water quantity. The two methods have great defects, the service life difference of the filter element is great under the environment with different raw water quality, the method for replacing the filter element can not accurately reflect the actual service life condition of the filter element, huge waste of replacing the filter element in advance can be generated in the early replacement, and the water quality of the water produced by the RO water purifier can be influenced if the filter element is not replaced in time. Residual chlorine molecules, oxidation-reduction potential and ion conductivity in the water filtered by the water purifier are high or the total amount of soluble solids is within a preset threshold value, so that the water purifier meets the standard of direct drinking. The existing water purifier has the technical problem that after the existing water purifier is used for a period of time, the purification effect of a filter element is continuously reduced, even the filter element is damaged and loses efficacy, and the quality of outlet water is poor. The traditional water purifier is lack of a technology for detecting the water quality index on line, so that a user cannot accurately know that a filter needs to be replaced and the effect of the filter is unknown. When the activated carbon filter is overdue and is not replaced immediately, organic matters and residual chlorine in tap water can not be effectively removed, so that the drinking water health problem is caused. Meanwhile, residual chlorine can damage a subsequent RO reverse osmosis membrane, so that the service life of the reverse osmosis membrane of the water purifier is greatly shortened. When the reverse osmosis membrane is damaged and not replaced immediately, the Total Dissolved Solids (TDS) in the water rises, so that harmful metal ions, such as heavy metals like lead, cannot be removed, and health may be seriously harmed.

Consumer upgrading is pushing home appliances to be intelligently transformed, wherein online detection of water quality is always a difficult problem. Latest intelligent water purifier has gradually integrated TDS electrode and has monitored reverse osmosis membrane's operating condition, can report to the police immediately after reverse osmosis membrane became invalid, reminds the user to change. There are also individual high-end machines that use semiconductor spectrometers to monitor total organic content (TOD) so that the operating conditions of the activated carbon filter can be monitored, and failure alarms can be issued and users can be alerted to replacement. However, the spectrum module is expensive, cannot monitor the content of residual chlorine in water, and is limited to be applied to household appliances. Although professional industries such as environmental monitoring and the like have residual chlorine, pH and ORP electrodes with high accuracy, the electrodes are huge in size and expensive due to the adoption of the traditional electrode structure and materials. For example, the mainstream chlorine residue electrode in the market is a probe with a diameter of 2 cm and a length of more than 10 cm, the price is up to thousands of yuan, and the electrode cannot be applied to a water purifier and other household appliances using tap water. At present, no water purifier can monitor the residual chlorine content in water in real time in the market. Due to various limitations of technology, price and the like, at present, no household appliance can simultaneously monitor multiple indexes such as residual chlorine, ORP, TDS and the like.

Therefore, there is a need for a water quality detection pipeline, a water quality detection system, an intelligent water purifier and an intelligent household appliance, which can detect the quality of purified drinking water.
