Problems solved by technology
However, the test process of this test method is complicated, and the test process lasts for a long time, which cannot meet the on-site online test; in addition, during the test process, the capillary needs to be inserted from the drain pipe into the refrigerator, and the test process is easy to scratch the refrigerator. Cause indirect losses and fail to meet the online test requirements

The invention provides a refrigerator sealing performance detection method and device and a medium, and the method comprises the steps: obtaining the pre-configured parameter information of a refrigerator, wherein the parameter information comprises first duration time T1 and a first vacuum degree P1 corresponding to the first duration time T1; when the refrigerator door body is in a closed state,vacuumizing the refrigerator refrigeration chamber from the outlet of the communicating channel, wherein the communicating channel communicates the refrigerator refrigeration chamber with the exterior of the refrigerator, and the outlet is formed close to the exterior of the refrigerator; when the duration time of the vacuumizing treatment reaches the first duration time T1, monitoring the secondvacuum degree P2 of the refrigerator refrigeration chamber at the outlet of the communicating channel; and if the second vacuum degree P2 is smaller than the first vacuum degree P1, determining thatthe sealing performance of the refrigerator does not reach the standard. The testing process is simple and convenient, the sealing performance of the refrigerator can be detected online in real time,unqualified products are prevented from flowing into the market, and the user experience is improved.
Description
technical field [0001] The invention relates to the technical field of household appliances, in particular to a method, equipment and medium for detecting the sealing performance of a refrigerator. Background technique [0002] The refrigerator door seal is a kind of refrigerator accessory used to realize the seal between the refrigerator door and the box body, and it mainly plays the role of sealing and preventing leakage. If the door seal is not tight, the refrigerator will leak seriously, and the temperature of the air in the refrigerator box will not reach the set temperature, causing the compressor on the refrigerator to run at high load for a long time; this will cause the energy consumption index of the refrigerator If it is unqualified, the service life of the compressor will be shortened, and the consumption of refrigerant in the refrigerator will be accelerated. In addition, if the refrigerator door seal is not tightly sealed for a long time, the heat and mass exc...
