The invention belongs to the technical field of electric appliance detection and provides a household electric appliance fault detection method and device. Timing and power detecting are conducted on preselected household electric appliances and faulted household electric appliances according to a function execution sequence so that a standard database and a fault database can be obtained; then, binary parameters in the standard database are compared with binary parameters in the fault database according to the function execution sequence, corresponding power anomaly maintenance prompts or time anomaly prompts are sent out when it is determined that the binary parameters in the fault database are abnormal, and corresponding parameter redundancy prompts are sent out when the total number of the parameters in the standard database is unequal to that of the parameters in the fault database. Thus, accurate fault maintenance prompts can be provided for maintainers, and maintainers are helped to quickly and accurately judge faults and take specific maintenance measures. Besides, no parameter needs to be preset during fault detection, so that universality of fault detection of various household electric appliances is enhanced.
Description
technical field [0001] The invention belongs to the technical field of electric appliance detection, and in particular relates to a method and device for detecting a fault of a household electric appliance. Background technique [0002] At present, home appliance testing instruments are gradually developing in the direction of intelligence, and the application of various types of home appliance testing instruments has become a new development highlight in the home appliance testing industry. Especially for household appliances with many load components, the corresponding maintenance steps are relatively complicated. In order to solve the problem of long maintenance time due to the large number of components that need to be disassembled during the maintenance process, in the prior art, it is generally through the household appliance testing instrument Detect the real-time load operating power of household appliances at a certain moment, but it is impossible to compare the cur...
