| Zusammenfassung: | The invention provides a welding missing and welding blocking detection device and method for a refrigerator. The welding missing and welding blocking detection device comprises an air source interface; a first detection pipeline; a second detection pipeline; an airflow switching valve group; the measuring assembly is arranged on the first detection pipeline and the second detection pipeline so as to obtain the gas flow and the gas pressure of the first gas outlet end of the first detection pipeline and the gas flow and the gas pressure of the second gas outlet end of the second detection pipeline; and the processor is used for determining whether the target pipe section of the refrigerating loop has the welding missing and blocking conditions or not according to the flow difference value of the detection gas between the first gas outlet end of the first detection pipeline and the second gas outlet end of the second detection pipeline and/or the gas pressure value of the first detection pipeline or the second |
