Embodiment Construction
[0037] A household appliance drop test system and its control method according to the present invention, such as figure 1 , figure 2 shown.
[0038] Firstly, the main power supply is used to supply power to the entire test system. The working voltage of different functional units is different, so the voltage of the main power supply is lowered to the working voltage suitable for each functional unit through the step-down unit before supplying power. Then the user inputs test parameters to the system through the control panel unit, such as setting the rising time to 2 seconds, the falling time to 2 seconds, the falling time to 1 second, and the number of tests to 1000. The processor unit receives the test parameters input by the control panel unit and serves as the execution standard for controlling the entire test system. Then fasten the falling object on the traction pan, the falling object can be the tested falling electrical appliance, or it can be a load. The processor...

The invention discloses a household electrical appliance drop test system. The system comprises a main power supply, a voltage reduction unit, a control panel unit, a processor unit, a time unit, a driving mechanism, a traction drop apparatus, a positioning detection unit and a switch signal generation unit. When the processor unit determines that a test is not completed, enabling signals are cyclically emitted to the driving mechanism until test frequency is reached. The work principle is that soft traction driving is employed, the influence of traction driving is eliminated when a traction disc sags, and test errors caused by mechanical resistance of the driving mechanism are reduced. At the same time, the time unit calculates the frequency and interval time in the whole test cycling process, such that it is ensured that stay time after an impact can reach a national test standard, and there are fewer errors. When over hundred or even one thousand and ten thousand tests are carried out, manual mechanical repetition is completely unnecessary. Therefore, the labor cost is greatly reduced, the test precision is improved, and a test result completely accords with requirements of a national standard and an international standard.
Description
technical field [0001] The invention relates to a household appliance testing system, in particular to a system for household appliance drop testing. [0002] The present invention also relates to a control method for a household appliance test system, in particular to a control method for a household appliance drop test system. Background technique [0003] Home appliances must pass the national safety standard or international safety standard test before they get the quality certification. Different home appliances have different test requirements, for example: the standard requirement for electric irons "drop the electric iron from a height of 40 mm on a rigid supporting steel plate with a thickness of at least 15 mm and a mass of at least 15 kg, and the test rate shall not exceed The frequency of 20 times is carried out 1000 times. When conducting the test, the electric iron should be kept on the steel plate for about 15% of the test time." The standard requirements of ...
