Embodiment Construction

[0018] The present invention will be further explained below in conjunction with specific embodiments.

[0019] A method for testing the safety performance of a single-tub washing machine proposed by the present invention comprises the following steps:

[0020] S1: Appearance inspection, the user should not be able to touch the exposed live parts in the internal structure of the washing machine, and the user's hands should not be able to touch the internal wiring at the opening of the washing machine;

[0021] S2: Insulation resistance test, connect the plug of the washing machine to the ground of the shaker meter and the two ends of the circuit respectively, and test the insulation resistance of the washing machine. The insulation resistance value of the washing machine in the dry state should not be lower than 2MΩ, and at the same time in the wet state The insulation resistance value of the washing machine should not be lower than 5MΩ, then it is qualified;

[0022] S3: Wit...

Abstract

The invention discloses a method for checking the safety performance of single-container washing machines. The method comprises the following steps: S1, appearance check; S2, test of insulation resistance; S3, voltage withstanding test; S4, grounding performance test; S5, test of leak current; S6, test of actual power; S7, test of breaking performance; S8, heating test of the washing machines; and S9, completion of the whole safety performance check of the washing machines after steps S1-S8 are completed, wherein qualified products are delivered to next procedure, whereas unqualified products are delivered to a repair line. The method for checking the safety performance of single-container washing machines is comprehensive and detailed in check contents, convenient to operate, high in test result accuracy and high in reliability of product judgment result.

Description

technical field [0001] The invention relates to the technical field of washing machine inspection, in particular to a method for inspecting the safety performance of a single-tub washing machine. Background technique [0002] With the rapid development of science and technology, washing machine products have also added intelligent elements. Now the market of household washing machines has gradually shifted from manual operation to intelligent products. When using a fully automatic washing machine, the user only needs to put the clothes and the washing machine into the washing machine, and then adjust the function keys of the washing machine to the corresponding gear. There is no need for real-time monitoring during use, and the operation is more convenient and fast, saving time and effort. Nowadays, the production of washing machines tends to be automated. The production process adopts the form of assembly line to improve the production efficiency of products. However, beca...
