A device for water purifier testing

Abstract

The invention disclose a device for water purifier testing. The device comprises a water source and several parallel testing units. Each testing unit comprises a water purifier to be tested, a purified water storage tank, a waste water storage tank, a pure water barrel, a waste water barrel, four solenoid valves and two liquid level sensors. The water source is connected to a water inlet of the water purifier. A water purifying water outlet of the water purifier, which is located at one side, is connected to the water inlet of the purified water storage tank, and the waste water outlet which is located on the other side is connected to the water inlet of the waste water storage tank. The water outlet of the purified water storage tank is connected to the water inlet of the pure water barrel through a first solenoid valve, and the water outlet of the pure water barrel is connected to a drainage pipeline through a second solenoid valve. The water outlet of the waste water storage tank isconnected to the water inlet of the waste water barrel through a third solenoid valve, and the water outlet of the waste water barrel is connected to the drainage pipeline through a fourth solenoid valve. The two liquid level sensors are arranged on one side of tops of the pure water barrel and the waste water barrel. The device is suitable for purified water flow, total purified water amount andrecovery rate (purified water production rate) testing of the water purifier, a test result is reliable, and accuracy and reliability are high.

Description

technical field [0001] The invention relates to the field of household appliance testing, in particular to a device for testing water purifiers. 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] The test method of water purifier performance is mainly based on QB / T 4143, QB / T 4144, GB / T30307, ​​GB / T35937, GB34914 and other standards. These standards have requirements for the water purification flow and total water purification volume of the water purifier. , Some standards also have requirements ...

AI Technical Summary

Problems solved by technology

The above method has the disadvantages of low degree of automation and many artificial interference factors

In addition, during the test of the water purifier, once the purified water flow rate does not reach the nominal value, the test needs to be stopped. Since the manual test cannot always control the information, there will be a shortcoming of lagging behind when problems occur.
