The refrigerator door seal is a refrigerator accessory used for realizing sealing between a refrigerator door body and a refrigerator body, and mainly plays roles of sealing and cold leakage prevention. If the door seal is not tight, the refrigerator leaks cold seriously, the temperature of the air in the refrigerator body does not reach the set temperature, and the compressor on the refrigerator runs under high load for a long time; therefore, the energy consumption index of the refrigerator is unqualified, the service life of the compressor is shortened, and the consumption of the refrigerant in the refrigerator is accelerated. In addition, if the refrigerator door seal is not tightly sealed for a long time, the heat and mass exchange between the inside and the outside of the refrigerator is frequent, and the leakage part of the refrigerator door seal can be condensed or even frozen. The airtightness of refrigerator door seals has therefore been of high interest to manufacturers of refrigerators.
In the prior art, the detection of the sealing performance of the refrigerator is usually offline sampling detection, and in one embodiment, the detection is performed by adopting an illumination method; specifically, the refrigerator is randomly drawn on line, then light is placed in the refrigerator, and after a refrigerator door body is closed, the sealing performance of the current refrigerator is judged by manual assistance through light leakage; the detection time of the implementation mode is long, manual visual inspection cannot be realized quantitatively, on-line detection of the refrigerator cannot be realized, and detection data cannot be traced.
In order to solve the problem of manual quantification, another embodiment is, for example, the following Chinese patent application No.: 201810460971.2, application name: in the embodiment, a door seal is installed on a refrigerator door liner, no gap is formed around the refrigerator door liner after the refrigerator door liner is closed, the refrigerator is kept at room temperature for 12 hours and then runs for 2 hours, then the power is cut off, a differential pressure meter flowmeter is calibrated, the connection part of the detection device is coated with soap water to detect the tightness, a pressure regulator is closed, an air compressor is started, the pressure regulator is slowly rotated, the flowmeter is monitored to reach a stable set value, and the pressure meter is started to read after the pressure meter is stabilized by monitoring that no bubble exists at the soap water, so that the refrigerator door seam airtightness is monitored. However, the test method has a complex test process and a long duration time, and cannot meet the field online test; in addition, in the testing process, the capillary tube needs to be inserted into the refrigerator from the drain pipe, the refrigerator is easily scratched in the testing process, indirect loss is caused, and the online testing requirement cannot be met.
