Problems solved by technology

[0005] 1. The function of the water supply system is single, and most of them can only meet one indicator. For example, they can only provide constant pressure water supply, but cannot guarantee the constant temperature function; those that can provide constant temperature water supply, but cannot guarantee the constant pressure function, so the final test data cannot be guaranteed. accuracy;
[0006] 2. The water supply system does not have the function of adding standards, and the test water needs to be manually configured. There are many manual interventions, which is not conducive to the scientific evaluation of the water purifier;
[0007] 3. The degree of automation in the water supply system is not high, there is a lack of corresponding protection measures, and the safety and reliability of the system are poor

Abstract

The invention discloses an automatic water supply system for testing water purifiers, which mainly includes a pure water source, a steam generator, a liquid storage tank, a refrigeration unit, a water supply tank and a water supply pipeline; the pure water source is connected through a solenoid valve and a flow meter to the water supply tank; the steam generator is connected to the liquid storage tank and the water supply tank through a solenoid valve; the liquid storage tank is connected to the water supply tank through a liquid distribution pump, a solenoid valve, and a flow meter; one side of the water supply tank is connected to the water supply tank through a solenoid valve A refrigeration unit is connected; the water outlet at the bottom of the water supply tank is connected to the water supply pipeline through a water supply pump, a pressure sensor and a temperature sensor in sequence. The invention has the characteristics of regular flushing, steam disinfection, automatic liquid dispensing and closed-loop control, and is suitable for various test items of water purifiers, which can effectively ensure the scientificity of test data, reduce the test cost of water purifiers, and improve the detection of testing personnel efficiency.

Description

technical field [0001] The invention relates to the field of household appliance detection, in particular to an automatic water supply system used for water purifier testing. Background technique [0002] With the development of society, a large amount of organic matter and heavy metals enter the water source through different ways, and the drinking water source has been seriously polluted. In recent years, people's living standards have gradually improved, and their health awareness has also been continuously improved and strengthened. The problem of drinking water has received more and more attention. In order to ensure healthy drinking water, many families choose to install water purifiers. [0003] At present, the testing methods of water purifier products are mainly based on NSF42, NSF53, QB / T 4143, QB / T 4144, GB / T30306, GB / T30307, ​​GB 34914 and other standards. Various tests such as efficiency, A+ certification and removal rate are in urgent need of a water supply s...
